Potential Career Paths in Animal Science in Western Australia Research Paper

Potential Career Paths in Animal Science in Western Australia - Research Paper Example Christiansen’s Farms enjoys average annual revenue of about $ 155 million (Anonymous). Christensen Farms is composed of individuals who collaboratively work together with the fundamental belief that different ideas and perspectives lead to better decision making. Christensen Farms enjoys being the leading innovator in the industry of pork production while at the same time enjoys new links to food chain in the farm. To ensure high quality products, the farm raises pastured Berkshire pork because it is tender, moist and flavorful pork that anyone can find anywhere. Job Description Located in the Midwest of the United States, Christensen Family Farms has one mission of being the leader in the production of wholesome, safe and high quality pork products to its customers (Anonymous). The organizational structure of the company is grouped into the management and non management levels. The management level includes the executive, who are four in number, and farm managers, who are sev en. The job functions are finance, marketing, sales, operations, and human resources among others. The position of the job in this structure is that of the farm manager in any of their farms. The specific daily tasks that are involved in this position are overseeing the general performance of the entire farm which includes motivation, Planning, organizing, directing, coordination and control of the farm. With the help of department supervisors, the manager also ensures that the employees carry out their tasks perfectly, the pigs are well fed, their houses are clean, the swine are slaughtered at the right time and at the right age, the processing of the products is carried out effectively and smoothly, and that the products are well stored to avoid contamination or spoilage. The manager’s main duty is to ensure that everything goes on smoothly so that the farm can increase its productivity for long-term profitability. Strengths and Weaknesses of the Job The job of a farm manag er has both strengths and weaknesses. Some of the strengths include: you are free to make the farm’s decision, you are the boss at the farm level, and you can enjoy many benefits like good housing, transport, medical, among others. Moreover, this job helps one to gain managerial experience as well as interactions with people from different social status. However, there are weaknesses in this job because the decision that you make must be well analyzed to ensure that the farms meet all its objectives, besides realizing profits. On the other hand, it is very hard to make decisions sometimes yet you may have no one to consult. Furthermore, all employees in the farm are answerable to you, something that makes this job very hard as some employees are very difficult to handle. The manager also has to deal with complex issues like resolving conflicts, firing rebellious employees as well as hiring new employees. All these call for not only academic qualification but good interpersona l skills. Interview Lessons for my Career Path From the interview, I learnt that this job can be a good starting point for my career dream of being a CEO in the future. This is because, it provides the skills and experience required to manage an even bigger farm or a much higher position. My future vision is to serve in a position that will give the opportunity to serve many customers with high quality products that ensure value for their money, as well meeting all the production

Traditional Structured Systems Analysis and Design

Traditional Structured Systems Analysis and Design ABSTRACT: After surveying many articles as well as the current and popular textbooks on Systems Analysis and Design which include but are not limited to those mentioned in the references, tI have observed much discussion on the use of object-oriented analysis and design over the traditional structured systems analysis and design. While the use of OOAD methodology is justified in many cases, in some cases it may be inappropriate and we should consider the use of the traditional structured analysis methodology in the design and development of information systems. This essay attempts to clarify the use of these methodologies, to compare the advantages and disadvantages of each and to make recommendations. 1. INTRODUCTION The existing methodology used primarily in industry today in building computer-based applications is known as structured analysis and design. This methodology came into existence as a result of the structured programming techniques introduced in the 1970s. This structured systems development methodology (SDM) has been fine-tuned and used for many years in the real world. However, during the last several years object-oriented languages have become increasingly more popular and more widely used in industrial organizations as well as university institutions. As this trend continued a methodology was developed to assist the programmer with the development of applications using object-oriented languages. This methodology has become known as object-oriented analysis and design (OOAD).The OOAD strategy approaches the problem from an object perspective as opposed to a functional perspective, which is the primary focus of the traditional structured development methodology. During the last few years the increasing use of OOAD over the traditional structured development methodology has spread significantly. As newer and more sophisticated object-oriented languages are created, there appears to be an even greater need for an object-oriented approach to develop business applications. However, does this need warrant greater use of this new methodology over the traditional one? We will compare the two methodologies and their advantages and disadvantages in order to address this problem. 2. TRADITIONAL SYSTEMS ANALYSIS DESIGN The systems development life cycle (SDLC) or the structured systems analysis design methodology (SSAD) is a framework of activities and tasks that need to be accomplished to develop an information system. This methodology as mentioned previously is called the waterfall model as each major phase of the methodology flows downward into the next phase (Wu and Wu, 1994). Consequently, this methodology is a strategy consisting of various techniques, tools, documentation and tasks that need to be integrated in order to develop the system. The SSAD is based on the concept of functional decomposition where the analyst breaks down the system into the basic processes that make it up and then breaks these down into smaller ones and so on until the analyst understands all the essential components of the system being investigated (Senn, 1989). The basic principles of the SSAD methodology can be summarized as follows: (1)The first principle of SSAD is top down functional decomposition. Here the system is considered in its entirety where the analyst first tries to understand the key features of the system, ignoring the smaller details until later. (2)Next the scope of system is defined where the physical details of the existing system are analyzed. The analyst focuses on two objectives: what the new system should do and how it should do it. (3)This methodology requires that the user be involved from the beginning to the end of project development. The analyst will meet with the user regularly to resolve problems and validate the users needs. This also requires that the analyst possess highly developed communication skills. (4)The two primary concerns in developing an information system are processes and data which are modeled independently with this methodology. The processes are modeled by the data flow diagrams which illustrate the flow of data between processes and data stores and how it is altered as it moves through the system from source to destination. Data models are defined by entity-relationship diagrams (ERDs) which describe the data (entities) and the various associations among them. (5)This principle of independently modeling the data and processes continues throughout the design phase. The schema for the conceptual database model is defined and the database is developed, normalized and populated with data during implementation. At the same time the process model is transformed into modules to be developed, and this phase also includes developing the detailed program logic. From the structure charts and program logic the program modules are then developed. Finally, to validate that the system meets the users requirements, goals and objectives, we subject the system to various levels of testing. 3. OBJECT ORIENTED ANALYSIS DESIGN Object-oriented analysis and design (OOAD) is a software engineering approach that models a system as a group of interacting objects. Each object represents some entity of interest in the system being modeled, and is characterized by its class, its state (data elements), and its behavior. Various models can be created to show the static structure, dynamic behavior, and run-time deployment of these collaborating objects. There are a number of different notations for representing these models, such as the Unified Modeling Language (UML). The object-oriented approach to system development views an information system as a collection of interacting objects that work together to accomplish tasks. Conceptually there are no separate processes or programs; there are no separate data entities or files. The system in operation consists of objects. An object is a thing in the computer system that is capable of responding to messages. Consequently, the OOAD methodology can be broken up into two major areas: (1) Object-oriented analysis. This is concerned with developing an object-oriented model of the problem (application) domain. These identified objects represent entities, and possess relationships and methods that are necessary for the problem to be resolved. Object-oriented analysis (OOA) applies object-modeling techniques to analyze the functional requirements for a system. Object-oriented design (OOD) elaborates the analysis models to produce implementation specifications. OOA focuses on what the system does, OOD on how the system does it. Object-oriented analysis (OOA) looks at the problem domain, with the aim of producing a conceptual model of the information that exists in the area being analyzed. Analysis models do not consider any implementation constraints that might exist, such as concurrency, distribution, persistence, or how the system is to be built. Implementation constraints are dealt during object-oriented design (OOD). Analysis is done before the Design.The sources f or the analysis can be a written requirements statement, a formal vision document, interviews with stakeholders or other interested parties. A system may be divided into multiple domains, representing different business, technological, or other areas of interest, each of which are analyzed separately. The result of object-oriented analysis is a description of what the system is functionally required to do, in the form of a conceptual model. That will typically be presented as a set of use cases, one or more UML class diagrams, and a number of interaction diagrams. It may also include some kind of user interface mock-up. The purpose of object oriented analysis is to develop a model that describes computer software as it works to satisfy a set of customer defined requirements. (2) Object-oriented design. This is concerned with developing an object-oriented model of the system necessary to implement the specified requirements. The analysts and programmers must think in terms of things (objects) rather than processes or functions. Object-oriented design (OOD) transforms the conceptual model produced in object-oriented analysis to take account of the constraints imposed by the chosen architecture and any non-functional technological or environmental constraints, such as transaction throughput, response time, run-time platform, development environment, or programming language. The concepts in the analysis model are mapped onto implementation classes and interfaces. The result is a model of the solution domain, a detailed description of how the system is to be built. Although object-oriented technologies have existed for quite some time, the phrase object-oriented has gained much popularity (along with buzzword status) in recent years. Indeed, the phrase is often bandied about with reckless abandon, which serves to obscure its real meaning. To further confuse matters, it is used to describe everything from development environments to programming languages to databases. So what does the term object-oriented really mean? The term seems to be thrown about indiscriminately; anything from programming languages to drawing tools might be labeled as object-oriented. There are primarily three uses of object-oriented methodology: object-oriented analysis (OOA), which deals with the design requirements and overall architecture of a system; object-oriented design (OOD), which translates a system architecture into programming constructs (such as interfaces, classes, and method descriptions); and object-oriented programming (OOP), which implements these programming constructs. So, object-oriented can be taken to mean the various methodologies, described briefly herein, used to design and implement software. 4. CONCLUSION For a specific application the first task is to decide which methodology is most appropriate for its development. Sometimes we may have to adapt different methodologies. Some guidelines might be that simple tasks may be better achieved by structured programming methods while the use of object-oriented methods might be better suited for higher levels of abstraction. This may also help with module design and problem decomposition. For situations in which the data is more likely to change than its functionality, objects would be more appropriate. In order for companies to transition from the SSAD methodology to the OOAD methodology, they need to understand the substance of the change and the barriers that must be overcome; otherwise moving to this new methodology may end in failure. Consequently, for analysts and programmers to embrace this new methodology, they need to reorient their thinking from the functional perspective to the object perspective. More specifically for analysts and programmers with experience in the traditional methodology, training should be given to emphasize the modeling aspects of the methodology as opposed to learning the syntax and features of an object-oriented language. The transition from SSAD to OOAD can be made easier by supervised training and the use of object-oriented tools. Although the OOAD methodology provides many benefits, it does not resolve all the issues associated with the traditional SSAD methodology. There are still some shortcomings and weaknesses that need to be addressed which include: the amount of training needed, the time necessary to learn the new methodology, and the amount of money to invest in it. According to Glass (Glass, 2002) there is no guarantee that the adoption of a new technology will result in it being used effectively and efficiently. In addition, if the organization completely submerges itself in the new OOAD methodology, there can be costly and destructive results. Consequently, to take advantage of all the positive benefits that the new methodology offers, the organization needs to develop a carefully planned and gradual introduction of the methodology to all the system developers. Before any effort is made to use the OOAD methodology as mentioned previously, it is imperative that the necessary education be provided in order to assure its success. The skills, knowledge and experience of the systems analyst and programmers who are indoctrinated in the traditional SSAD methodology can be enhanced by the new methods. Since changes to the basic structure of the OOAD methodology are stressful to manage, first attempts to use this methodology should be applied only to small scale and non critical applications. This will enable the company to receive immediate feedback and to have time to make any necessary modifications in the application of the OOAD methodology. Consequently, the benefits and advantages gained from using the new OOAD methodology can be much greater and more rewarding for the organization in the long term than using the traditional SSAD methodology.

Macbeth - Macbeth Is A Statement Of Evil :: essays research papers

Discuss "Macbeth is a statement of evil" (L.C Knights) Do you consider this a fair summary of the play? The character Macbeth is portrayed by Shakespeare as the larger view of evil’s operation in the world. Shakespeare accomplishes this by using a powerful and unsuspecting character such as Macbeth. The audience sees how evil, tempts Macbeth. Furthermore the use of messages addressing to or addressed by, how evil Macbeth is. The Evil inside Macbeth is quite evident; for he commits several murders. Finally, there are certain analogies, which suggest that Macbeth is comparable to Satan. Shakespeare intended on using a hero of good deeds such as Macbeth, as his figure. He is seen as a good advocate of Satan’s evil conduct: for an evil person is one you least expect. Macbeth starts off as a humble man and a saviour of his native soil. After returning from a heroic victory, Ross, a noble Thane, describes what a significant officer Macbeth is for his kingdom: "The king hath happily received, Macbeth, The news of thy success; and when he reads Thy personal venture in the rebel’s fight, His wonders and his praises do contend Which should be thine or his. Silenced with that, In viewing o’er the rest o’th’ selfsame day, He finds thee in the stout Norweyan ranks, Nothing afeard of what thyself didst make, Strange images of death. As thick as hail Came post with post, and every one did bear Thy praises in his kingdom’s great defence, And poured then down before him." [I.iii.89-99]. Macbeth, like any other man, had succumbed to some form of temptation. Shakespeare utilizes him as a model, to show how no matter how strong you may be; even the strongest man can be taken in by evil. When Macbeth came across three witches [I.iii], was tempted by evil, then fell for it. His character, being a solid and heroic one, becomes severed off from his men and his creator [God] for the point that he reached out to evil. Macbeth saw how the only way he could become king, was alternatively taking his own path away from that of God [betraying God, who wrote that his destiny was not to become a king], with the help of Satanic or evil forces to accomplish his inner most desire. The audience sees how a devilish Macbeth is automatically broken off the path of God, as the witches discussed his position as the bearer of the throne.

René Descartes Essay

Philosophy begins as an art of wondering. This art of wondering, leads man into asking a number of questions about himself and the world around him. Variations in philosophical thoughts as result questions posed by man, help in modification of philosophy. The purpose of this essay therefore, is to do a comparative analysis of Sophie’s World by Josteen Gaarder with three philosophical texts: George Berkeley’s Treatise on Human Knowledge, John Locke’s Essay on Human Understanding and Rene Descartes’ Passions of the Soul. We shall also show the roles of authors and texts in Philosophy. TREATISE ON HUMAN KNOWLEDGE VERSUS SOPHIE’S WORLD One of the outstanding efforts of Berkeley in this work was to show that the world exists as it does because of the ideas perceived by the mind of God and as such, existence of things depends on their perception through the senses. Likewise in Sophie’s World, Aristotle through his belief showed a similarity with Berkeley’s stance in this text Treatise of Human Understanding. For Aristotle, highest degree of reality is what we perceive with our senses. Berkeley also said that existence is the state of being perceived by a perceiver, but on the contrary, Descartes in Sophie’s World believed that he exists because he thinks. It furthermore means that his existence depends on his ability to think. He used such words like cogito ergo sum (latin) and je pense, donc je suis (French) all meaning `I think therefore I am` to illuminate his thesis on this. Plato while stressing the sovereignty of reason in Sophie’s World said that the reason can only give us the true reality of things and as such contradicted the empiricist approach of Berkeley. ESSAY ON HUMAN UNDERSTANDING VERSUS SOPHIE’S WORLD John Locke illuminated in this work that idea is derived from experience of sensation or reflection, just like it reflected in Sophie’s World in which his fellow empiricists likewise stressed the inevitability of experience as the source of true knowledge. David Hume in particular established that man has two types of perceptions, namely: impressions and ideas. By `impressions` he means the external sensations of reality. By `ideas` he means the recollections of such impressions. Aristotle the trail blazer of empiricism, in alignment with the empiricists believed our reason to be completely empty until we have sensed something. John Locke in this book made an attempt to refute the notion of `innate ideas` by proving that it does not exist, whereas in Sophie’s World, philosopher like Plato believed in an innate idea, an external world of ideas outside of the natural world. Descartes even believed that the idea of God is innate. PASSIONS OF THE SOUL VERSUS SOPHIE’S WORLD Descartes defined passions of the soul as a mental state or thought that arises as a direct result of brain activity and such passions can move us to action. He also suggested that one needs to learn to control one’s passions, for they can move one to perform vicious acts. Benedict Spinosa in Sophie’s World, suggested that we must free ourselves from our feelings and passions only then shall we find happiness. Conversely, also in Sophie’s World, the Epicureans through the teachings of Aristippus believed that the aim of life is to attain the highest possible pleasure or passions and by so doing, they contradict Descartes belief. AN EYE ON THE ROLES OF AUTHORS AND TEXTS IN PHILOSOPHY Authors in philosophy play incredible roles in modification of philosophy through their texts. There various attempts to answer the underlying questions of nature and man have led to the developments of dialectical methods like thesis, antithesis and synthesis used in philosophy today. An eye on the three authors and philosophers: Descartes, Berkeley and Locke whose works where compared with Sophie’s World above showed the vital role they played in philosophy. While Descartes was a rationalist, Berkeley and Locke were empiricists, but through their texts, they contributed in `epistemology` or theory of knowledge. CONCLUSION Having done these comparisons, we can see the successful deduction of similarities and differences between the Sophie’s World and three aforementioned philosophical texts. I attest that Sophie’s World is necessary philosophical paraphernalia needed by a neophyte in Philosophy as seen from its versatility in the course of this comparison done, and also how it covered aspects of history of Philosophy in such a sublime manner.

Poor Lifestyle Essay

In the modern world, the modern urbanites are living in a tense community. Consequently, they might have different kinds of poor lifestyle in their life. According to Woods (2010), poor lifestyles always include smoking, drinking, poor diet and lack of exercise, which perhaps lead to a higher chance of cancer. However, it could be environmental pollution. Health plays an important role in people’s life. Therefore, it is essential to choose the right food or the right healthier way in your life. Moreover, environmental pollution could influence people in their lives as well. This essay will discuss about health issue on quality of life and how environmental pollution affects human’s lives nowadays. On the one hand, the healthy diet is more and more popular in this society. Hamer, Molloy and Stamatakis (2008) claim that there is a connection between the level of physical activity and diet or nutrition that people consume from the different foods. When a person eats immoderately, the calorie would be transformed to fat or cholesterol which is harmful for people’s health. It means that they will become overweight or obese. There are some dangerous factors if they are suffering obesity such as cardiovascular diseases, high blood pressure, body pain, being out of breath, easily tired and disability. Although people also eat a great deal of fruits or some natural food at the same time, it might be produced some harmful effects. For instance, eating too much animal fat is a main cause of sickness or ill health also our bodies need a little but most of us eat too much. Some people know saturated fat. Therefore, it could make the person get a disease and be overweight (BBC n.d.). However, there are numbers of fats in fish, chicken, eggs, turkey, duck, beans, dog, lentils and foods made from these. Unsaturated fat may be better for the people, but eating too much fat of any type can gain their weight. It is better to buy a small amount of lean meat rather than fatty meat or solid fat. The best way is to eat more fish or different kinds of nutritional food and do not forget to get a high iron intake by eating something like liver and bitter foods. Some traditional meal, they use pulses provide good nutrition, to reduce the use of animals fat in the cooking. (Morbidity, Mortality, 1996) On the other hand, environmental pollution could lead to poor lifestyle as well. The pollution could happen in many different sources such as contaminate water, air, and light. At first, the indoor air pollution will make children and teenager getting diseases. Cooking and heating with solid fuels on some open fires or traditional stoves will produce small particles and carbon monoxide, especially for young children and women. According to the Global Health Risks, indoor air pollution leads to 2.7% of world diseases. (WTO n.d.) Furthermore, air pollution also leads to higher temperature and green house effect. Take Chicago as an example. Many residents feel like it is too dangerous because of the high humidity and air pollution. People with pulmonary and respiratory diseases are very sensitive so they should limit their activitiesï ¼Ë†CDT, 2011ï ¼â€°. Secondly, water pollution would threaten tap water quality. According to the EWG, the biggest sources of contaminants are agriculture and industry. The environmental group finds the water that people drink everyday which contains about 260 chemical contaminants altogether. The pollution will be more dangerous to the citizens and pose a great threat on the human beings. (Larry West, n.d) As suggested above, environmental pollution is divided into several aspects, such as air pollution and water pollution, which might contribute to poor lifestyle. Nevertheless, every kind of pollution will damage our lifestyle so people should be aware of the risks. In addition, the government ought to lay down some laws to stop air pollution. This is because it could avoid deterioration of contamination. However, in developing countries , where pollution is strictly regulated, it still has much more things need to do. In conclusion, health and environmental pollution have a huge effect in the life. Air pollution is known to could affect people’s health as well.If a person had good health, they can do anything they want. As a result, people need to be care about their diet and lifestyle. It could save their health and lead the people more happy. Nevertheless, environmental pollution could affect the person. Even though the people are healthy. All show that poor lifestyle is unhealthy in this community. Reference: 1. Hamer M, Molloy GJ, Stamatakis E.

The Underground Railroad essays

The Underground Railroad essays No matter what difficulties lay ahead, there was only one goal, to be free. It was the road to freedom; it was a challenge that needed to be completed. The foreshadowed consequences and high risks shed no fear upon the slaves. The journey was going to be difficult. It was down to making the decision of whether to die in the dimness of slavery, or to attempt to become free. Although many chose to give up in the idea of freedom, the slaves who escaped found freedom using the Underground Railroad. The Underground Railroad was an opportunity that was not to be missed. In the time of slavery, it was a secret system known to help the slaves escape the cruel treatment of their owners. The success of the Underground Railroad was centered in Pennsylvania where the involvement of the Quakers made it possible. Without the help of the Quaker people, The Underground Railroad would not have been successful. The early movements to begin the Underground Railroad were secretive and successful. The Underground Railroad was neither a road nor underground; it was any number of houses, caves, hidden rooms, and empty barns, and it was any place a runaway could safely hide (Buckmaster, 42). The first movements of the Underground Railroad began with the involvement of the Quakers. The Quakers formed an important core group along with freed black men and woman, and began an abolition movement. The core group developed an escape network first known as the underground road, and then later it changed to the Underground Railroad. It operated before and during the American Revolution and through the 1800's. The group slowly began to advance, and the slaves became more aware of this group, and successfully kept it subtle. The Underground Railroad metaphorically resembled a voyage, where stops would be made to pick up more people. In the times of slavery, the supporters and conductors would lead the v oyage, and "pick up" more slaves, to reach their destination,...

Free Essays on Effects Of Second Hand Smoke

Anti-smokers have long tried to restrict smoking on the grounds that it was bad for smokers' health. But this sort of paternalism, while it has many merits, is not very effective when it comes to getting laws passed. At least not in this country. In recent years, however, they have made great progress using the theory that smoking is bad for the health of others: that Environmental Tobacco Smoke (ETS) can, in fact, be deadly. The phrase "respiratory illnesses", when used in connection with ETS, is usually found appended to a list of other claims, as in "cancer, heart disease and ..." It seems to round off the list nicely and is purposely left vague. If pressed, anti-smokers will, as if by rote, recite "... such as asthma, colds, influenza and pneumonia". But none of these ailments is caused by smoking, much less by ETS. Pressed further, the antis will backpedal to the claim that ETS "aggravates" these conditions. Since 1979, the number of smokers has declined significantly, from about 33% of adults, or higher, to a proportion varyingly reported as being from 20% to 25%. During the same period, a host of anti-smoking laws have dramatically curtailed smoking in public places. Today, exposure to ETS is not one tenth of what it was in 1979. So where are the mystery deaths caused by "respiratory illnesses" that can be blamed on ETS? There aren't any. The diabolical innuendo of the phrase"... cancer, heart disease and respiratory illnesses" causes many to believe people die this way and to repeat the rumor. But it is akin to saying† nuclear bombs, biological warfare and firecrackers (Tang 613)." With the pending challenge to the EPA's report, that is about to change. For a preview of the truth likely to emerge, we have only to look at a recent Australian court case in which the Australian Department of Occupational Health, Safety and Welfare was pressing a complaint against a casino in an attempt to enforce a no-smoking law.

Free Essays on Effects Of Second Hand Smoke Second-Hand Smoke Effects Issues on smoking have arisen in the media once again, so much so that now the government is debating whether or not this drug should be banned in public places. Exposure to second-hand smoke is the third leading cause of preventable death in the United States only behind alcohol and active smoking. There is a need to aggressively combat this health hazard. The attitudes of smokers who recognize this problem view the problem as a nuisance and continue to put others at risk. With the annoyance of the smell and smoke of cigarettes, it is obvious that advancement in banning smoking in public places must be professed. Everyone doubts that â€Å"firsthand† smoke is deadly to people’s health leading to lung cancer and heart diseases in adults; asthma and bronchitis in children. Now, the tobacco industry is onto the second-hand smoke. Several anti-smoking organizations are trying to turn smoking in public into a private activity that does not have to involve nonsmokers breath ing second-hand smoke. What is even more important is that many of these organizations convinced a lot of smokers to cut back or quit completely. The problem of second-hand smoke is increasing because it is so common in our society. It makes second-hand smoke the third-ranking cause of lung cancer among nonsmokers. Even in the most elegant restaurants non-smokers are bombarded with exposure to second-hand smoke. â€Å"So-called† smoking sections are almost never useful because the smoke always drifts into the non-smoking eating area. Exposure to second-hand smoke causes several negative reactions on the body of all non-smokers regardless their physical well-being. Second-hand smoke is the smoke exhaled from smokers which comes from the burning end of a cigarette, cigar or pipe. This smoke from the burning end of a cigarette, releases several thousand poisonous chemical compounds (Martin 1). Some of the toxic and cancer causing agents found i...

How to Melt Gallium Metal in Your Hand

How to Melt Gallium Metal in Your Hand Gallium is an unusual metal. It does not occur as a pure element in nature, but can be purchased in pure form to be used for some truly amazing science demonstrations. One of the most popular gallium demonstrations is melting gallium in the palm of your hand. Heres how to do the demonstration safely and the explanation for how it works. Melted Gallium Materials pure gallium  plastic gloves (optional) You can buy a chunk of pure gallium for around $20 online. Its safe to use your bare hand for this experiment, but gallium has two properties that may make you wish to wear a pair of disposable gloves. First, gallium metal wets both glass and skin. What this means is the melted metal will leave finely divided gallium particles on your skin, giving it a grayish cast. Its not super-easy to wash off, so you might want to avoid the issue. The other consideration is that gallium attacks other metals. So, if you usually wear a ring, you may want to wear gloves just to make certain no gallium or leftover metal is available to discolor your jewelry. How To Melt Gallium What could be easier? Simply place the piece of gallium in the palm of your hand and let the warmth of your body heat do the work! The melting point of gallium is  29.76 C  (85.57 F), so it will readily melt in your hand or in a very warm room. Expect this to take around 3-5 minutes for a coin-sized piece of metal. When you are done examining the gallium, tilt your hand to allow the metal to flow into a non-metal container. If the container is also warm, the slow cooling will allow you to watch gallium form metal crystals. You can supercool gallium, which is holding it as a liquid above its freezing point. Do this by pouring the liquid gallium into a warm container and keeping it free of vibrations. When you are ready to crystallize the metal, you can jar the container, touch the sample, or seed crystallization by adding a small piece of solid gallium. The metal exhibits an orthorhombic crystal structure. Points To Keep in Mind Gallium may temporarily discolor your skin. This is because it wets skin. Keep in mind this means youll lose a tiny bit of your sample every time you do the demonstration.Some people have reported mild dermatitis (redness, itching, inflammation) from long-term gallium exposure to skin. Basically, this means you should wash your hands after the conclusion of the demonstration.Gallium is not toxic. It is used in pharmaceuticals, so you could probably swallow it and be okay, but its not recommended, plus it would be an expensive snack.Gallium attacks other metals, so do not let it come into contact with jewelry or store it in metal containers.Gallium expands as it cools, so it usually kept in a plastic bag or flexible container rather than glass to avoid any possibility of expansion shattering the container. Also, gallium wets glass, so storing in plastic helps minimize sample loss. Other Elements That Would Melt in Your Hand Gallium is not the only metal that melts into a liquid near room temperature or body temperature. Francium, cesium, and rubidium also would melt in the palm of your hand. However, you seriously dont want to attempt this demonstration with any of them! Francium and cesium are radioactive. Cesium and rubidium react vigorously with water, which basically means they could set your hand on fire. Stick with gallium. Learn More About Gallium If you have gallium to melt in your hand, you may also wish to try the melting spoon trick. In this science magic trick, you either melt a gallium spoon with what appears to be the power of your mind or else you make it seem to disappear in a glass of hot water. Gallium is an interesting metalloid, so you may wish to learn more about the element.

Innovation Management Essay Example | Topics and Well Written Essays - 3250 words

Innovation Management - Essay Example Not just the adjustment in the earth is making organization receive new patterns, for example, it increases spending to have the capacity to meet the aggressive basic, yet these patterns additionally add to an increment in the instability. From a systemic point of view, the outcomes of these activities can be opened up past desires by the interrelatedness of the components prompting the conclusions that the very results of organizational activities are progressively eccentric. This clear mystery of innovation is normally a common marker of complex systems at work. For this situation, the utilization of innovation to improve the possibilities of survival of the firm, by endeavoring to control its surroundings, winds up compounding advance nature rendering it more turbulent. This expanded vulnerability prompts multilevel flimsiness with direct outcomes: both new dangers and new open doors for organizations. Expanding the turbulence in a situation does not mean actuating a change in all measurements consistently in the meantime. These adjustments in the earth can be seen as instabilities for a few organizations and consequently make dangers. Then again, these progressions can likewise be "arranged" to bring open doors for the organizations that made them. Turbulence might frequently be close to genuine rivalry from organizations in full control of the commercial center. This is what is known as the test of the hypothesis to see how organizations change and change themselves while in the meantime changing and changing their surroundings.

The Separation of the Church and the State In the United States of Research Paper

The Separation of the Church and the State In the United States of America - Research Paper Example However, it could be noticed that the impending procedure of the law and how the church usually meddles with the procedures of the state in implementing the law in several occasions make this particular aim of separating both factors of the society somewhat unreal at several points of consideration (Boston, 2005, 18). This is the primary reason why this particular study is being commenced. The examination of the situation is indeed an important discussion as it directly affects the entire society and how religion and the law could be balanced as they are exercised in society. The issue being discussed in this paper is primarily based on the basic idea of the need of separating the responsibilities as well as the power of church and the state. This is primarily because of the separate aims of both sectors that make them particularly different from each other. Mixing both sectors of social function certainly brings about different conflicts within the systems of both sectors of the soc iety. (Mc Whirter, 1994, 16) The demarcation line between the state and the church begins with the educational amendments of the American practice in assisting the students gain knowledge about the Divinity of Religion towards the political involvement of the church within the different occasions that the government intend to decide on several issues that concern the society (Owen, 2000, 32). Because of the believed guidance that the church receives from the Grand Creator of all Things, some people tend to derive decisions from the church rather than simply relying on the law. (Hamburger, 2002, 47) Certain Protestant clergymen of the United States give much lip service to the principle of the separation of church and state. They loudly denounce any breaching of that wall by others, such as former President Truman's proposal to send an ambassador to the Vatican. But do they respect that wall of separation between church and state when it conflicts with their own interests to do so They do not (Owen, 2000, 43). Th e "Released Time" program by which school children are released from public schools so that they can take religious instructions elsewhere is a case in point. This program breaches the wall of separation in that it uses the state's compulsory school machinery to supply classes for religious organizations (Awake! 1989, 24).     

Good Grocers, Inc Essay Example | Topics and Well Written Essays - 750 words - 1

Good Grocers, Inc - Essay Example This calls for the consideration of a mediator’s assistance. In addition, since ,mediation can be applied at any stage of a conflict, the two parties may consider adopting it. The mediator will support the two parties in exploring ways through which they can resolve their differences. Each of the parties may or may not consider a lawyer’s services when going to the mediation. This will depend on the nature of the problem (LexisNexis, 2013, p.78): the problem seems a bit serous since the customer plans to sue the manager, therefore, both parties may need a lawyer. Both parties must always consult their attorney before finalizing the agreement so that they can be sure that they have made complete informed decisions. This will also enable them determine whether all their rights are protected. In this situation, the mediator will help manage the mediation process and facilitate reconciliation between the two conflicting parties. The mediator will not determine the decision nor enforce an agreement. The two parties will participate directly and will be responsible for devising and enforcing their own agreement or settlement. The mediation can be done at the mediator’s office or an agreed location. When the mediation commences, the mediator will explain the process and the essentials such as rules. Either parties or their respective attorneys will have the chance of explaining their opinions in consideration to the dispute. The mediator will support them in understanding each other’s opinion. In some instance, the mediator may meet each of them separately. This may assist in addressing factual and emotional issues and offer both sides the time to receive legal advice from their attorney (LexisNexis, 2013, p.79). Generally, the agreements may be creative. The two parties may end up reaching a solution that is not present in a court of law. For instance, the manger after an agreement with the customer, may

Price Elasticity of Demand Coursework Example | Topics and Well Written Essays - 1750 words

Price Elasticity of Demand - Coursework Example   For example, if the price of fuel increase by 20%, the reaction would be that the demand for new Vehicles that are fuel inefficient will reduce by 40% and therefore cross elasticity of demand will Be -2 (-) cross elasticity represents two commodities that are complementary, while (+) cross elasticity represent two substitute commodities. In above example, the two commodities, fuel and vehicle are complements to mean that one commodity is used by the other. In such a case, cross elasticity of demand is (-) as evidenced by a reduction in demand for vehicles when fuel price is raised. Everybody needs salt in food and nothing else can substitute salt. Therefore, when the price of salt goes high, then more is spent on it. Also, the same case would be for people who want to build stronger and permanent stone buildings. They must need cement and therefore if the price of cement increases, more will be spent on it rather than thinking of adjusting to another product. Two commodities are substitutes when the cross elasticity of demand is (+) to mean that when the price of one commodity increases, the demands of the other commodities rise. For instance, if the company that makes Rhino matches increase their prices significantly, then the customers are most likely to adjust to other types of matches rather than paying more for the same Rhino match at an increased price. The same would apply if the Sony Company that manufactures electronics increases the prices of their products, customers will opt for similar products manufactured by different companies and which are sold at a fair price. This is because the other companies can produce substitutes that meet the customers’ demands. Elasticity determinants: the availability of substitutes, substitutability, and time has to be put into consideration because even with the increase in prices and the customers turning to substitutes, every business will continue running. Hence, for the commodities with many substitut es, the merchant will have to create special offers from time to time to attract the customers unlike the commodities with inelastic demand. Then some products like salt signify a minute portion of the customer’s financial plan resulting in reduced concentration being given to its price. Also if a commodity is the only option in the market, then its substitutability becomes very minimal. e.g roller skates. If they are the only skating gadgets then the customers will not be very perceptive to its price variations since, after all, they require them for skating.

Change And Change Management At Sony Essay Example | Topics and Well Written Essays - 3000 words

Change And Change Management At Sony - Essay Example Sony, an electronics company as indicated in the case underwent very many changes due to the retrogression in economic strength it was experiencing. Two categories of change occur in the company; people related changes and organization related changes. The first change that occurred at the company was the drop in the value of the company share from a high of $150 to a very low value of $25. The drop in the value of the shares of any company is a clear indication that the real value of the company had gone down. In this case, the drop was a very high of 83%. An urgent action was desperately needed here to rescind the situation given that the drop took just three years. The second change was that one of breaking from the norm (cultural change). In 2005, a non-Japanese took over the leadership of the company. This was a change from the normal norm in which only Japanese top management had been in control. Having been in charge of the American unit, he had the record of integration of al l units and creative coherence for a better progression in the country. This was important in that the record was the change that was required in the country and the world as a whole. More change came in after the executive; Howard Stringer took over the top management of the company (leadership change). With the company facing stiff competition from the other companies in the industry; Samsung and Apple, the first change that inevitably followed was streamlining of the company into five production groups. There was need to specialize in electronics, television, DVD recorders, digital imaging and the portable audio. This was stimulated by the fact that some of the companies competing Sony were moving away from the CRO televisions and adapting flat screen television sets. Apple was embracing the killer iPhone which had so many properties that it was almost full taking over the market. Every change was coming with the resultant consequences which were dubbed change in themselves. Elev en plants were closed and 10,000 employees were laid off. According to Cordrey (2010), such a step is taken to remain with the most effective personnel in operation. When he joined the company, Stringer found out that the decision making process was autonomous across all the units. The autonomy, he found out was creating internal strife and imbalance. This autonomy was inclusive of the key decisions of the company. On this, the change he made was that of centralizing all decision making processes in the company. Over the product lines, the decision was to make it possible for easier decision making processes to take place. His goal was to make SONY products to operate seamlessly with one another in the communication. To save on the cost spend on research and development, the new executive had to eliminate product redundancies which had been adopted by the seamless networking of the company products. The change realized here is in the mode of spending in which there was need to reduc e the expenditure on such unnecessary items like the extended research that was being done (structural change). Sony products had worked miracles over the years and they were still doing fine until the simplicity of the other company products came to the market. This change was brought about as a result of the realization that the customers were not just interested in the complex Sony products but were also interested in the ability to operate the products. The overall outlook of the items at Sony needed to change and this is seen in the simplicity of the Apple products that force the general thought at Sony to change (technological change). The last plan that happened at the company was that leading to the

Descartes and Darwin Essay Example | Topics and Well Written Essays - 1000 words

Descartes and Darwin - Essay Example Secondly, the paper will explore how history and modern science has added more weight to the views of Darwin which suggests that this view may be more ‘correct’ in its nature. The Debate on Human Nature One of the most well-known parts of Descartes’ philosophical views is the concept that to be human is to be composed of two incompatible pieces; the body and the soul. The body is full of the natural processes, whilst the soul contains all the information that we need to be ourselves, including all of our decision-making faculties and our personalities (Descartes, 2006). These two components, perhaps communicating through the pineal gland, are thoroughly different in composition and matter. Descartes would argue that human nature is partially comprised of the soul which cannot be explained by science and therefore there are elements of ourselves that science cannot explain. Descartes did, however, suggest that â€Å"the mind depends so much on temperament and the disposition of one's bodily organs that, if it is possible to find a way to make people generally more wise and more skilful than they have been in the past, I believe that we should look for it in medicine† (Descartes, 2006, p45), meaning that there are some elements of human nature which should look to science for explanation. Charles Darwin had very different ideas. Often known as the father of evolution, Darwin explored a great number of scientific concepts pertaining to human and animal behavior, often finding that these two concepts were linked and very similar. This view can be illustrated from Darwin’s words that â€Å"it has often and confidently been asserted, that man's origin can never be known: but ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science† (Darwin, 1871, p4). This just shows Darwinâ€℠¢s faith in science, and the power of science to explain even the inexplicable. Human nature is no exception from this rule, and as Darwin suggests, â€Å"there is no fundamental difference between man and the higher animals in their mental faculties† (Darwin, 1971, p34). Having studied a number of animal behaviors throughout his career, it is obvious that Darwin had more interaction with different creatures and therefore more information to draw his strong conclusion about human nature from. As the father of evolution, it is obvious that Darwin will favor an evolutionary perspective of human nature, one that suggests that all elements of our behavior and other aspects of being a human can be explained by science. Although there were some gaps in the evidence Darwin provided for this hypothesis, these have been slowly filled since the publication of The Descent of Man and are continually being updated as time goes on. It is perhaps the fact that Darwin’s work fits so n eatly with modern science which makes it the more appealing hypothesis, as explained further below. These views are evidently at odds with each other. Although Descartes does alert the reader to the importance of science and medicine, it is evident from Discourse on the Method that there are some things that Descartes feels are inexplicable. This may seem like a feasible resolution to come to, as human nature and personalities appear to be extremely complicated and different from those of other

Computer sciences and technology Essay Example | Topics and Well Written Essays - 500 words

Computer sciences and technology - Essay Example Today, the internet has become an indispensable tool to every facet of the human civilization; be it political, social, or economical. As clichà © as it sounds, it made the world smaller. By connecting people thousands of leagues apart, it altered the way the world interact and helped the culture of each nation evolve towards a more globally centred one. If one will ask any high school student about the essence of the internet, the answer he will probably get is, â€Å"to be connected to anyone in the world†. With the advent and dominance of social networking sites such as Facebook and twitter, it is not surprising at all to have such a mainstream response. After all, the internet is every bit about connectivity. It is about building bridges from one part of the world to another; about destroying the barriers of each culture in order to let them grow and embrace positive changes. The internet has allowed the social scope of every culture to focus not only on a single-race interaction, but rather to foster a multi-racial relationship. Forty years ago, before the internet was born, social interaction is on a more personal level. People can talk just about anything under the sun – from the things they are interested the most to the not so interesting topics at all – with them conversing face to face. Although interaction through the internet can never be as personal as before, the integration of a multi-cultural perspective makes every topic of conversation as interesting, if not even more. This mixed perspective is the primary factor pushing socialization to greater horizons The internet has played a great role in reshaping the face of Politics, particularly its dynamics. It has completely revolutionized how political campaigns are carried out. It can be a highly effective platform with which political views can be shared to persuade people to vote for a candidate. Social networking sites and blogging are now being tapped as a way to

Emerging Technologies: Business And Society

Emerging Technologies: Business And Society Over the last decade, emerging technologies have no doubt influenced almost every sector of society and business. Whether by their promise of better society and business or by the curse of disquiet etched in their wings; Robotics and Nanotechnology, among a few other emerging technologies, have certainly played a part in shaping todays business and society for tomorrow. The emergence of Nanotechnology and Robotics was, to some extent, instigated and inspired by certain fundamental needs and pursuits of society and business. The business desire for cost-efficiency and societys pursuit of sustainability in the form of better health care, a cleaner environment, security, etc are just a glimpse of what may have triggered the emergence of these among other technologies. However, the technologies success, or lack of it, is to a large extent dependent on, the overall short and long term, how well they respond to the primary needs and pursuits of businesses and society. This report focuses on Nanotechnology and Robotics discussing some of their varied range of practical, theoretical and experimental applications. The report, in essence, draws from the diverse applications of these two technologies, their implications and impacts on businesses and society hitherto and perhaps in the near future. The analysis, also acknowledges and draws from lessons learnt in preceding and contemporary technologies such as genetic engineering and nuclear energy. The analysis shows that the success of the technologies depends on their close evolutionary interaction with their resident businesses and society which are also changing in response albeit at a different pace. Introduction The influence of emerging technologies on almost every sector of business and society cannot be overstated over the last decade. Whether by their promise of better society and business or by the curse of disquiet etched in their wings; Robotics and Nanotechnology, among other emerging technologies in the frontline, have certainly played a part in shaping todays business and society for tomorrow. The emergence of Nanotechnology and Robotics may, to some extent, have been instigated and inspired by certain fundamental needs and pursuits of society and business. The desire for greater efficiency cost or otherwise in business, better health care, a cleaner environment, security and etc for sustainable society are just a glimpse of pursuits that may have triggered the emergence of these two among other technologies. However, just as their preceding or contemporary counterparts such as genetic engineering, their success, or lack of it, is to a large extent dependent on the overall short and long term impact they portend for business and society. Robotics and Nanotechnology are two among the foremost of countless emerging technologies ushered into the new century whose impact on society and business is yet to be fully realised or determined. Determining the impacts of these two is no simple task. The range of applications for these two technologies, whether already practical or still theoretical, is quite enormous and diverse making it even more difficult for one to establish the full extent of their impact. There is however no doubt that these two have had their share of both positive and negative impacts on business and society and will continue to during their evolution. Whatever the impacts, their measure may be drawn from how businesses and society have responded so far. Many studies done on these technologies indicate enormous initial investments by businesses and more recently, measured but nonetheless important investments by society. Nano-scale technology or Nanotechnology has been defined generally as the creation of functional materials, devices, and systems through control of matter on the nanometer (1 to 100+ nm) length scale and the exploitation of novel properties and phenomena developed at that scale. [1] Nanotechnology, just as many other technologies before, has especially pledged enormous benefits for businesses and society. Many studies indicate enormous initial investments by businesses and more recently, measured but nonetheless important investments by society anticipating mostly the benefits it promises. Nonetheless the studies also show that it bears its own brand of curses or threats alike especially for society. Some of the threats may well be known, anticipated and resolved in good time. Others may only be revealed later on in its evolution. Either way, it is imperative that its benefits and identifiable threats be reasonably considered and embedded in their evolution if these two, among others related, are going to succeed. On the other hand, a robot is generally defined as a reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks (Robot Institute of America, 1979)[15]. Robotics is thus concerned mainly with the study, design, building and operation of robot systems for certain specialised tasks [14]. Business and societys desire for greater efficiency cost and better health care, a cleaner environment, security etc respectively also continue to inspire heavy investments in more cost-efficient technologies. Achieving these either by automation, miniaturisation or by the use of better building blocks or materials for technology and products are among the main approaches that converge research and development of Robotics and Nano-scale technology or Nanotechnology among other related technologies. Apart from the brief introduction above, this report is organized into two main sections. The first section covers a brief description on the fundamentals of Nanotechnology. This section is followed by discussions on some of the principle practical, theoretical and experimental applications tracing and focusing on their impact on business and society. The second section deals with robotics and likewise describing the fundamentals of robot systems. This section too is followed by an examination of the major applications of robotics with a focus on their impact on society and business. Nanotechnology As mentioned in the introduction, Nanotechnology generally involves engineering at the nano-scale level (1 to100nm) leveraging novel properties and phenomena of matter at this scale. The concept of engineering at this scale may well be attributed to Feyman (1959) [2]. Modern understanding of Nanotechnology as defined above was built on the initial concept by other eminent scholars like Drexler (1992) [3]. Merkle (1997) [4] also went on to propose additional concepts like building materials by specifically positioning each atom and cost effective mass-assembly of the atoms At the close of the last century in 2000, presented with the anticipated advances and subsequent benefits of Nanotechnology by proponents such as Drexler (1992)[3], Merkle (1997)[4] among others, galvanized leaders in technological research and development, cutting edge innovation and business to converge and discuss extensively the implications of engineering at this scale. At a workshop organized by the United States National Science Foundation (NSF), leading experts gathered and to present their views on Nanotechnology and its implications focusing its potential applications in business and society. A resulting report on the proceedings of the workshop presents rather varied views and perpectives, perhaps due to the diverse applications of the technology or backgrounds of the participants. However, the urgent need for a foundational and comprehensive analysis of the technology and its implications seems to be the leading theme. This was a defining moment in the evolution of Nanote chnology. Below is a summary of nanotechnologys focus and principle applications as reported in the NSF (2001) [5] workshop and are being refined with time as shown in the National Nanotechnology Initiative Strategic Plan (2007) [6]: Industrial Manufacturing Materials and products, Chemical Processing Electronics application in Information Technologies and Communications Medicine and Health applications in Medicine and Pharmaceuticals. Aerospace For aerospace and planetary exploratory applications. Transportation and civil infrastructure Lighter Materials Sustainability in Energy, Water, Agriculture Food, Materials, Clean environment Defence and Security applications. Even though the current and potential applications of nanotechnology reach deeper than revealed by the above summary, there is no doubt that the above applications have impacted both businesses and society over the last decade in one way or another. Some researchers have even suggested at the emergence of Nanotechnology signalling the entry into the Age of Transitions [6] [7] there would be profound waves of change whether in society or business. Impact of Nanotechnology on business Every category of application highlighted above is representative of a range of industries and businesses that have already responded to, or must soon do so, to the diverse and vast influences, potential or practical, wielded by Nanotechnology. Some of these influences are certainly not unique to nanotechnology and may have been wielded by contemporary and preceding technologies. Others, however, such as the rapid parallel advances in research and development hardly witnessed by preceding technologies have compelled many a business in any of the application categories to reconfigure itself and its approach. These cycles of reconfiguration will even be more rapid when Nanotechnology converges with other emerging technologies that portend similar characteristics. Good examples are traffic on the internet; wireless capacity and computing performance which are said to double every 6, 9 and 18 months respectively [7]. Industrial Manufacturing: Nanoscale engineering of materials and products forms the bulk of current and perhaps even future applications of nanotechnology in industrial manufacturing. This has witnessed the introduction of new materials and products and thus new markets for businesses over the last 10 years. The U.S. National Science Foundation (NSF) forecasted the 2010 2015 Nanotechnology market at over 1 trillion US dollars as shown in the chart below. Chart 1: Estimates of the nanotechnology market by 2010-2015 USD trillions: 1.1 Source: National Science Foundation Subsequent research (RNCOS research) [8] has upwardly revised estimates within half the period settling at 1.6 trillion USD by the year 2013. The market estimates probably continue to inspire a steady increase in investment. Cientifica estimated the global government funding stood at a little less than 9.75 billion USD for nanotechnology. The US government alone invested 1.6 billion USD a steady increase from about 500 billion in 2001. [8] Apart from specialized materials such as nano-composite polymers and other nanoscale structured materials and chemicals; the inventory list of consumer products with a nanotech component currently stands at over 800 and will obviously continue to grow [9]. With this kind of diversity in terms of products and an expanding market, businesses, especially those in manufacturing, will do well to quickly adapt continue their success. Electronics: The potential application of nanotechnology in electronics is set to take the miniaturisation of computers to the next level. It is also set to improve the cost-efficiency and performance of electronic products even introducing product variation that have been hitherto unrealistic. [10] Figure 1: Manufacturing cost projection for logic at silicon-area and transistor levels as illustrated by Doering (2000) [5] As shown in Figure 1, the cost of achieving electronic function is on the decline thus inspiring the continued introduction of new electronic products and business and a consequent the market for the products. This will no doubt also augment advances in related areas such as telecommunications further opening up opportunities for business as illustrated in Doerings (2000) [5] projections in Figure 2 below. Figure 2: Illustrates projected growth of electronic market place with decreasing feature sizes and function cost. Doering (2000) [5] Medicine and Health: Nanotechnology has been applied in medicine, healthcare and pharmaceuticals to introduce better drug delivery and diagnosis mechanisms (targeted) [10] [11]. The resulting advances achieved hitherto continue to attract, not just government funding, but private businesses and organizations are also joining the fray investing themselves in nanotech medicine and healthcare. Of course theres the prospect, albeit some of it being still experimental, of resolving age old problems like cancer. Figure 3: An illustration of Nanotech funding Adapted from ETC Nanotech Report (2006) [11] There is also the prospect of making viable, products that have previously not been viable for business. The overall positive impact of nanotechnology on business related to medicine and health care is that it introduces a new range of products subsequently expanding the existing markets or even reconfiguring them all together [5], [10]. Some studies estimated the world markets expansion for these products from 1 billion USD in 2005 to be tenfold at 10billion USD by 2010 [11]. On the flipside, an expanding product base also means the introduction of products that carry along with them originally unintended effects or even products that are downright harmful to the business side of medicine and healthcare [10] [11]. Aerospace: Businesses and organizations in aerospace research and development have also invested themselves quite heavily with the intention of reaping some of the benefits of Nanotech application over the last decade or so. The introduction or potential introduction of lighter, stronger nanostructured materials or building blocks for aerospace equipment can only portend a positive outlook for this business since this ultimately implies an eventual reduction in costs e.g. in fuelling as well as wholesome aerospace projects [10]. Transportation and civil infrastructure: Lighter high-strength materials developed through nanotechnology implies a reduction of costs; whether in fuelling or maintenance in transportation and infrastructural developments. Impact of Nanotechnology on society The almost definitive nature of business, at least in objective makes much simpler the exercise of nanotechnologies impacts on business. This however, is not the case when it comes to determining societal implications and impacts brought about by technologies; nano or otherwise. Many attempted studies at this exercise acknowledge this difficulty [5] [10]. The period of time required for one to actually determine a certain technologys impact on society as well as the often unpredictable nature of society have been cited in the studies among major challenges to the accuracy of determining societal implication of technology; nanotechnology in this case. The impact of nanotechnology and its related advances on society hinges on certain major areas of life that are important to the makeup of that society. Below are some of the major areas cited by some studies like the NSF (2001) [5] report on Societal Implications of Nanoscience and Nanotechnology and the Royal Society Royal Academy of Engineering (2004) [10] report on Nanoscience and nanotechnologies: opportunities and uncertainties: Health care: Among the benefits pledged by nanotechnology, certain applications are meant to improve the quality of health care. Society at an individual level desires health and long life. New products and technologies such as targeted drug delivery mechanisms and diagnostics introduced by nanoscale engineering for health care promise a healthy and quality for individuals and society as a whole. [11] On the flipside, some products developed through nanotechnology also pose a threat to health. Some nanomaterials and particles have presented hazardous characteristics to human health and performance. Analyses and studies on some of the nano products and technologies which present unintended health hazards recommend responsible research and application of nanotechnologies [5]. Sustainability: Society looks for the sustainability of the resources that are its lifeblood. The current application and potential of Nanotechnology focusing on sustainable energy, water supply, agriculture food, materials and clean environment directly impact on the societys quality of life. Energy applications of nanotechnology pursue a parallel advance in achieving sustainable energy building on existing technologies. The threesome approach deals with: efficient energy conversion from primary form using a number of nanotech mechanisms e.g, nano-engineered solar cells, efficient storage energy storage through the use of supercapacitors developed through nanotechnology, and efficient energy saving mechanisms e.g. through the use of better thermoinsulators created using by nanomaterials [12] Sustainable energy is tightly bound with a clean environment. Achieving the former dramatically improves the later. Water supply is also an issue of concern for society where nanotech products and approaches are being used to improve the level of water supply either e.g. using nanotech for desalination. Agriculture and food production are also set to benefit from sustained research and development of nanotech application to agriculture. Defence and Security applications: Defence and security have long inspired the emergence of technologies perhaps because societies have often been reconfigured by conflict. The practical or even just the potential applications of nanotechnology to defence and security either in military weaponry and equipment or in intelligence continue to profoundly affect society. [5] A fundamental concern for society is who controls the resulting advances of nanotechnology thus raising legal and ethical issues. Studies show that society needs to respond at a quicker pace by being involved right from the get-go, putting in place and redefining policy mechanisms, regulation and control of these technologies [10]. Education and Culture: A combination of nanotechnology and other contemporary technologies such as Biotechnology and Information Technology portends a true Age of Transitions for society as has been argued by some experts [7]; a time when social structures and cultures are rapidly reconfigured and reengineered by a rapid technological evolution and eventual revolution. Robotics Robotics is area of emerging technologies that involves the study, design, construction and operation of robot system(s). Slightly variable definitions of a robot to encompass humanlike characteristics describe a broadened modern concept of robotics [13]. The application of Robotics, since the first practical realization of the concept in the early 60s, has increasingly worked its way into many sectors of todays business and society. The primary application of robotics has mostly to do with tasks that are either too dangerous or those that are too repetitive and too precise for humans. In essence, robotics seeks to enhance human performance. The general areas in business and society that continue to benefit from application of robotics in include [14]: Industrial, mainly in manufacturing either in precise or repetitive assembly repair among others so far the most established application of robotics. Healthcare performing complex and precise surgical procedures such as Radiosurgery, Tele-robotic surgery among other medical procedures. Aerospace, Military and security performance of dangerous and precise tasks relating to defence and security example of practical applications include the unmanned aerials and ground vehicles for surveillance, reconnaissance and exploration of hazardous environment. Agriculture Disaster Recovery and Infrastructure again, the use of robotics for the recovery and sometime repair of dangerous environments and difficult to reach areas of infrastructure respectively. Consumer Robotics for day-to-day tasks and service provision the least developed area of robotics but picking up pace. Impact of Robotics on business The robotics principle inspiration of enhancing human performance and the fundamental objectives of increasing productivity and quality in business foreshadow the impact of robotics in business. The application of advancing robotics to various areas of traditional business has and continues to compel change in business design and approach. Business and organizations trading in the primary areas of robotics application have had to reconfigure themselves inspired by this change. In many ways, the impact of robotics on manufacturing business foreshadows the impact of robotics on almost all other areas of industrial robotics application. Manufacturing thus may well be viewed as representative of other areas Infrastructure development, Agriculture and healthcare. Manufacturing: the extensive industrial application of robotics has, to a large extent, improved the efficiency of manufacturing businesses that have properly invested themselves in the potency of robotics. Case studies on some of these businesses show marked improvements in their performance, quality. Chrysler, for example, a leading automobile manufacturer was able to cut cost and improve its flexibility by remodelling its business for the market and by leveraging advanced robotics. Their application of robotics enabled them to cost-efficiently produce a wider range of products [16]. The increasing need for application of robotics in other manufacturing areas like packaging and processing is also opening up new business opportunities for robotics. The trend in manufacturing now is that more and more businesses are inclined to robotics and related automation for their existence. However, although the benefits of applying robotics are worthwhile on the long term for business, the initial investments are, more often than not, prohibitive. This has been the case and will probably continue to hound business into the next generation. Parallel advances in complimentary technologies however likely to mitigate problem. In healthcare, apart from the performance of repetitive tasks, the cutting edge application of robotics is mostly towards the performance of highly complex surgical procedures. However, robotics application here is tightly bound to the human in the sense that robots are not autonomous. Consumer robotics is a fairly new application area that involves a much smaller scale of applications compared to industrial. This might be at the product distribution level like dispensing machines Military and security: investments in robotics for military and security use are leading the advance in robotics as a technology through research and development. Often, the output of these advances translates to new business opportunities when converted or modified for civilian applications. Contemporary technologies such the internet and wireless telecommunication were first military and defence technologies before they became commercialized for business. Aerospace applications: Robotics application in exploratory research and development like aerospace are also contributing to the advancement of robotics and in turn inspiring fresh business area applications such as infrastructure maintenance and transport. Impact of Robotics on society As mentioned above, robotics portends to improve and enhance human performance. To some extent, this does impact society positively. A societys health and safety is improved for instance by the use of robots to perform dangerous and hazardous tasks. However, large scale industrial robotics application may mean job losses especially when robots begin to replace human workers. The implications here are far reaching. Apart from the short term effects of conflict, there is the long term reconfiguration of society to accommodate the changes. In the long term, education and training and other related areas have to be reviewed. There are also broader societal issues such as the need for environment sustainability where robotics portends both positive and negative impacts. The application of robotics in military defence, weaponry and security such as the use unmanned aerial vehicles for surveillance revisits the concern of who controls technologies thus raising legal and ethical issues. Robotics and other complimentary technologies continue to influence social evolution by directly effecting change in education and social culture. In other worlds robotics has contributed to the change in the way we live our lives. There is an increasing societal dependence on technologies even though they dont resolve age old societal challenges such as poverty and justice. Conclusion Emerging of technologies often invite scrutiny in the interest of business and society the ultimate consumers of technology. Nanotechnology and Robotics are no different. This scrutiny, as has been illustrated in this report, often takes the form of assessments on the impacts of these technologies on business and society. Again, as shown, assessing and articulating the impacts of technologies is not a simple exercise especially when they are just emerging. It is often a process informed by diverse and sometimes opposing views from leading experts and representatives from society and business. In the end, the impacts identified, positive or negative, define the viability of an emerging technology. The assessment of Nanotechnology and Robotics in this report, perhaps because of the width and depth of their potential applications, yields an overall positive outlook for business and society and in turn for their success as emerging technologies.

Tool Of The Trade :: essays research papers

Tool of the Trade In any game, the equipment players use determines the way the game unfolds. Try to imagine a soccer game played with an American football! Or try playing tennis with the wooden racquets of thirty years ago. Change the equipment, and you discover a very different game. As part of my look at baseball, I decided to examine the tool of the baseball trade: Bats. Perhaps the most crucial and visible tool in baseball is the bat. A bat is the offensive weapon, the tool with which runs are scored. To understand the history and science of bats, I read a magazine published by Louisville Slugger, in Louisville, Kentucky home of the Hillerich & Bradsby Company, Inc. (also known as H&B), the manufacturers of perhaps America's most famous bat, the Louisville Slugger. Through the reading I learned how the modern bat came to be, and what it might become. In 1884, John Andrew "Bud" Hillerich played hooky from his father's woodworking shop and went to a baseball game. There he watched a star player, Pete "The Old Gladiator" Browning, struggling in a batting slump. After the game, Hillerich invited Browning back to the shop, where they picked out a piece of white ash, and Hillerich began making a bat. They worked late into the night, with Browning giving advice and taking practice swings from time to time. What happened next is legend. The next day, Browning went three-for-three, and soon the new bat was in demand across the league. H&B flourished from there. First called the Falls City Slugger, the new bat was called the Louisville Slugger by 1894. Though Hillerich's father thought bats were an insignificant item, and preferred to continue making more dependable items like bedposts and bowling pins, bats became a rapidly growing part of the family business. Just as it was back then, the classic Louisville Slugger bat used by today's professional players is made from white ash. The wood is specially selected from forests in Pennsylvania and New York. The trees they use must be at least fifty years old before they are harvested. After harvest, the wood is dried for six to eight months to a precise moisture level. The best quality wood is selected for pro bats; the other 90 percent is used for consumer market bats. White ash is used for its combination of hardness, strength, weight, "feel," and durability. In past years, H&B have made some bats out of hickory.

Physics of the Turntable :: physics sound music

Have you ever wondered how a record player works? Probably not. After all, who still listens to records? Surprisingly enough, turntables are making a come back. With the recent surge of interest in hip hop music, popular attention has been turned towards the turntable, used by DJs to provide beats, loops and scratching for virtually all of today's hip hop groups. The inner workings of the turntable may seem complex at first but after reading this paper it should become clear that, like all things, the record player works on basic principals of physics. In fact, the turntable is remarkable in that the basic physical principles behind it are quite simple. Some of these will be explored here. Please enjoy your visit. How a record player works is quite simple. A motor is somehow connected to a solid disc so that the disc is rotated at a constant speed. On top of the rotating disc (platter), The record is placed on top, with a slip mat in between. The slip mat can serve two functions. In the past to hold the record in place so that it would not rotate independently of the platter. Now, however, the slip mat serves a much different function. Instead of holding the record in place, the slip mat is now used to reduce the friction between the spinning platter and the record. This way a DJ can scratch (manually move the record, usually at high speeds) the record while the platter continues to spin underneath. Once the record is rotating, a stylus glides along the grooves and picks up the vibrations, these are then converted into audible sound. There are many different models of turntables still being manufactured. Of those being sold, it is possible to divide them into two separate categories based upon their motor system. Virtually all record players being manufactured today have either belt drive or direct drive motors. For the reasons discussed below, direct drives are accepted as the industry standard for professional DJs and turntabilists. Belt Drive - There are two advantages to the belt drive design. The motor in a belt driven turntable is set away from the platter by means of a continuous belt loop. This minimizes vibration to the platter and thus needle skipping. Also, belt drive models tend to be much cheaper than their direct drive counter parts. These advantages, however, do not balance the many short falls of the belt drive design.

Ways to Fix Run Ons Fragments

Understanding sentence structure helps in identifying and correcting run-on sentences and sentence fragments. A computer’s spell checker does not typically catch these common mistakes, so do not rely on the spell checker to correct grammar for you. Be sure to carefully proofread all assignments for these issues. This handout defines various sentence structures, presents sample sentences, and provides strategies for correcting run-ons, comma splices, and fragments. Practice activities are included to help build skills in sentence clarity and variety. First, consider the parts of a complete sentence:Complete Sentence (Independent Clause) Table of Contents Part I: Run-ons †¢ Strategies for avoiding run-ons (comma splices and fused sentences) (p. 2-3) †¢ Sample sentences with explanations, practice activities (with answer key) (p. 4-7) Part II: Fragments †¢ Strategies for avoiding sentence fragments (p. 8-11) †¢ Sample sentences with explanations, practice acti vities (with answer key) (p. 12-13) Part I: Run-On Sentences Definition: A run-on sentence either has too many independent clauses or two independent clauses that are not linked correctly.Two types of run-on sentences are fused sentences and comma splices. Strategies for Correcting Fused Sentences: 1. Create a compound sentence. Inserting a coordinating conjunction (for, and, nor, but, or, yet, so) plus a comma correctly links these independent clauses. This sentence structure is called a compound sentence. Correct compound sentence: She writes the music, and he plays the guitar. independent clause + comma + coordinating conjunction + independent clause 2. Separate independent clauses with periods and capitalization, creating simple sentences.Correct sentences: She writes the music. He plays the guitar. 3. Insert a semi-colon. Semi-colons should be used sparingly and to connect independent clauses whose meanings are closely related. Correct sentence: She writes the music for Coldpla y; he plays the guitar for that band. * Note: When more details are added to the above independent clauses, the meanings become much more closely related. Thus, a semi-colon can separate these clauses. 4. Link ideas using a subordinate clause (dependent clause). Correct Sentence: While she writes the music for Coldplay, he plays the guitar for that band. ubordinate clause + comma + independent clause ‘While’ is a subordinating conjunction, which makes ‘while she writes music for Coldplay,’ a dependent clause. That is, the clause depends on the rest of the sentence for the overall meaning to be clear. A dependent clause cannot stand alone. Use a comma to separate a dependent clause that appears before an independent clause. *Note: A sentence constructed of one independent clause and one or more dependent (or subordinate) clauses is called a complex sentence. Strategies for Correcting Comma Splices: . Insert a coordinating conjunction to create a compound sen tence. Correct Sentences: She writes the music for Coldplay, but he plays the guitar for that band. She writes the music for Coldplay, and he plays the guitar for that band. Remember, the coordinating conjunction appears after the comma. *Note: Again, consider meaning before joining sentences. If the sentences are not closely connected, it may be best to keep them separate. Think about these two independent clauses: Today I was late for class. I will have a burrito for dinner tonight.Since these ideas are distinct, keep the sentences separate. 2. Insert a semi-colon. Correct Sentence: She writes the music for Coldplay; he plays the guitar for that band. Again, to join two independent clauses with a semi-colon, be sure that their meanings are closely connected. The Tutoring Center has a separate handout on semi-colon usage. * See pages 4-7 for further explanation of these strategies as well as sample sentences and practice activities. Run-On Sentences: Examples and Explanations Examp les: It was raining Naomi could not find her umbrella. (Fused)It was raining, Naomi could not find her umbrella. (Comma Splice) How to fix these run-ons: Step 1: Identify the independent clauses. It was raining + Naomi could not find her umbrella. subject + verb phrase subject + verb phrase (direct object) Step 2: Use one of the below strategies. 1. Period + Capital Letter (Separate Sentences) It was raining. Naomi could not find her umbrella. S + V. S +V 2. Comma + Coordinating Conjunction (Compound Sentence) It was raining, and Naomi could not find her umbrella. S + V , and S + V . Semi-Colon It was raining; Naomi could not find her umbrella. S + V ; S + V 4. Subordinating Conjunction + Comma (Complex Sentence) Though it was raining, Naomi could not find her umbrella. dependent clause, S + V *Note: Use the Tutoring Center’s Transitions/Grammar Aid Handout to help identify coordinating and subordinating conjunctions. Ask a tutor if you are unclear about the meanings of these conjunctions or in which situations to use them. Practice: Avoiding Run-Ons Correct the following run-on sentences by using the strategies previously discussed. 1.I moved to the United States when I was young it was easy to learn English, my parents were already here, they knew English already. ___________________________________________________________________________________________________________________________________________________________________________ 2. Juan and David recognized each other they had been in the first grade together. ___________________________________________________________________________________________________________________________________________________________________________ 3. Her car would not start she was late for class. ____________________________________________________________________________ ______________________________________________________________________________________________ 4. The parents ate the baby slept in her stroller. ___________________________________________________________________________________________________________________________________________________________________________ 5. Eli wants to quit smoking this habit is too expensive. ___________________________________________________________________________________________________________________________________________________________________________Avoiding Run-Ons: Answer Key and Explanations 1. I moved to the United States when I was young it was easy to learn English, my parents were already here, they knew English. Strategy 1: Period + Capital Letter (Separate Sentences) I moved to the United States when I was young. S + V (prepositional phrase) (dependent clause) It was easy to learn English. S + V (adverb phrase) My parents were already here. They knew English. S + V (adverb phrase). S + V (direct object)Strategy 2: Coordinating Conjunction + Comma (Compound Sentence) I moved to the United States when I was young, and it was e asy to learn English. S + V , and S + V My parents were already here, so they knew English. S + V , so S + V Strategy 3: Semi-Colon I moved to the United States when I was young; it was easy to learn English. S + V ; S + V My parents were already here; they knew English.S + V ; S + V Strategy 4: Subordination (Complex Sentence) Because I moved to the United States when I was young, it was easy to learn English. (dependent clause) + , S + V Because is a subordinating conjunction that makes the first clause dependent on the second clause. Do not use a coordinating conjunction to link a dependent clause and an independent clause; rather, use only a comma. For example: Since my parents were already here, they knew English. Note: This run-on sentence can also be corrected using a combination of the above strategies. I moved to the United States when I was young, so it was easy to learn English. (compound sentence) Because my parents were already here, they knew English. (complex sentenc e) More suggested answers: 2. Juan and David recognized each other; they had been in the first grade together. S + V ; S + V (prepositional phrase) Juan and David recognized each other, for they had been in the first grade together.S + V , for S + V Since they had been in the first grade together, Juan and David recognized each other. Since + dependent clause , S + V Juan and David recognized each other. They had been in the first grade together. S + V. S + V Now it’s starting to make sense: 3. Her car would not start, so she was late for class. Her car would not start, and she was late for class. Her car would not start. She was late for class. Because her car would not start, she was late for class.Her car would not start; she was late for class. (correct, but not the best choice) 4. While the parents ate, the baby slept in her stroller. The parents ate as the baby slept in her stroller. The parents ate. The baby slept in her stroller. The parents ate, and the baby slept in her stroller. The parents ate; the baby slept in her stroller. 5. Eli wants to quit smoking. This habit is too expensive. Eli wants to quit smoking; this habit is too expensive. Eli wants to quit smoking, for this habit is too expensive. Since this habit is too expensive, Eli wants to quit smoking.A more logical, concise construction using subordination would read as follows: Since smoking is too expensive, Eli wants to quit. Part II: Sentence Fragments There are several types of fragments. See pages 9-11 for detailed explanations and techniques for correcting fragments. Pages 12-13 include practice activities and an answer key. Types of Fragments Each example below illustrates a different type of sentence fragment. Any fragment can be corrected by linking the fragment to an independent clause—one which comes before or after it and which makes sense within the paragraph.Examples of Subordinating Conjunctions and Relative Pronouns |after |how |unless |whichever | |although |i f |until |while | |as |in order that/to |what |whether | |as if |once whatever |who | |as soon as |rather than |when |whoever | |as though |since |whenever |whom | |because |so that |where |whomever | |before |than |whereas |whose | |even if |that |wherever |why | |even though |though |which | | Strategies for correcting subordinating conjunction and relative pronoun fragments: 1. Connect the fragment to the sentence that comes before or after it. Correct Sentences: While I was waiting for my car to be repaired, I read a magazine. dependent clause , S + V Notice the use of the comma after the dependent clause (because the dependent clause falls at the beginning of the sentence).I had to ride the bus while I was waiting for my car to be repaired. S + V dependent phrase *Note: When a dependent (subordinate) clause comes after the independent clause, it is usually unnecessary to place a comma after that independent clause. Whether or not a comma is needed depends on the meaning of the sentence. 2. Remove the subordinating conjunction/relative pronoun. Correct sentence: I was waiting for my car to be repaired. S + V Strategies for correcting â€Å"ing† fragments: 1. Connect the fragment to the sentence that comes before or after it. Correct sentences: Her expertise being in chemistry and biology, she was not hired as an English instructor. ependent –ing phrase , S + V She designed the new science exhibit, her expertise being in chemistry and biology. S + V , dependent –ing phrase 2. Correct the verb form. Correct sentences: Her expertise is in chemistry and biology. Her expertise was in chemistry and biology. *Note: Sometimes you will also need to add a subject and correct the verb form. See the next page for an example. . Strategies for correcting missing subject fragments: 1. Connect the fragment to the sentence that comes before or after it. Correct Sentences: Security set off the alarm, evacuated the building, and closed ll the entrances. In the above sentence, it is clear that the subject, the doer of the actions, is security. 2. Add the missing subject. Correct Sentence: Security set off the alarm and evacuated the building. Next, they closed all the entrances. *Note: In this sentence, the pronoun ‘they’ renames the subject, security. Transition Words Indicating a List or Examples |also |especially |except |for instance |including | |in addition |furthermore |for example |such as |next |Strategies for correcting â€Å"extra information† fragments: 1. Connect the fragment to the sentence that comes before or after it. Correct sentence: Many Americans take basic amenities for granted, for example, clean water and electricity. S + V , dependent phrase 2. Add the missing subject and verb. Correct sentence: For example, basic amenities include clean water and electricity. transitional phrase, S + V Practice: Avoiding Fragments Correct these sentences using the strategies previously discussed. 1.

I cannot wait until President’s Day, finally, a day off. S +V, dependent phrase I cannot wait until President’s Day. Finally, we have a day off. S + V. S + V ———————– Avoiding Run-On Sentences, Comma Splices, and Fragments A complete sentence has (minimally) two parts, a subject and a verb. A sentence must also express a complete thought. Such a phrase consisting of a subject and a verb (with complete meaning) is also called an independent clause. Example: He writes music. This sentence has a subject and verb.This sentence also expresses a complete thought, so its meaning is clear. he=subject (S) writes=verb (V) music=direct object (DO) 1. Fused Sentence Definition: A fused sentence consists of two independent clauses, but both the comma and coordinating conjunction are missing . Example of a Fused Sentence: She writes the music he plays the guitar. ‘She writes the music’ and ‘he plays the guitar’ are each independent clauses, containing a subject and a verb and expressing complete thoughts. ‘He plays the guitar’ is an independent clause that can stand alone because it expresses a complete thought and is grammatically correct. he=subject (S)plays=verb (V)guitar=direct object (DO)However, in the above example, the independent clause, ‘She writes the music,’ incorrectly runs into a second independent clause, ‘he plays the guitar. ’ 2. Comma Splice Definition: A comma splice consists of two or more independent clauses that follow one another and are incorrectly linked together only with a comma (or commas). The coordinating conjunction is missing. Example of a Comma Splice: She writes the music, he plays the guitar. In the above sentence, a comma separates the two independent clauses, but a coor dinating conjunction is also necessary. 1. Subordinating Conjunction and Relative Pronoun Fragments Example: While I was waiting for my car to be repaired. How to find this type of fragment:When proofreading a paper, pay attention to subordinating conjunctions and relative pronouns. These words (see box below) turn subjects and verbs into dependent clauses. Identifying proper usage of dependent clauses can help in recognizing fragments. 2. â€Å"-ing† Fragments Example: Her expertise being in chemistry and biology. How to find an â€Å"-ing† fragment: If the only verb in the sentence ends in ‘–ing’ and does not have a helping verb, you have a fragment. While the word ‘being’ is a verb, in the above sentence, it is not properly formed. In the below sentence, notice that the ‘-ing’ verb has a helping verb: I was walking down the street when it started raining. (This sentence is correct. ‘Was’ functions as the hel ping verb. )When added to a verb, ‘-ing’ sometimes makes a verb do the job of a noun: Walking outdoors is my favorite form of exercise. (In this sentence, ‘walking’ is a noun that functions as the subject. ‘Is’ functions as the main verb. ) 3. Missing Subject Fragments Example: Security set off the alarm and evacuated the building. Next, closed all the entrances. How to find this type of fragment: The second phrase above (noted in bold) is a fragment because there is no subject. ‘Entrances’ is a noun, but it is the object of the verb ‘closed. ’ Who or what is closing the entrances is unknown. That is, the subject of the sentence is missing. 4. â€Å"Extra Information† Fragments Example: For instance, clean water and electricity. How to find and fix this type of fragment:
