Things You Wont Learn About Teaching in Grad School

Things You Wont Learn About Teaching in Grad School This could probably fill a book, but we'll start smaller. A traditional description of graduate school for education might go something like this: â?One to two years spent learning pedagogy, talking about behavior scenarios, and reading recent research on what kids today need.⠝ An alternative one might read: â?A nice resume boost and another requirement for the state to put on future educators.⠝ While I am being facetious with the latter description of grad school, I have found that the majority of my most useful teaching lessons came from actually leading a classroom, not being a student in one. Here are the four biggest areas where grad school was not enough preparation. 1. What Curriculum? The first teaching job I got after grad school is the one I still have four years later, but Year One looked different than Year Four. Going into a school with no established math or reading curricula left a lot open to interpretation. In grad school, you spend time learning about the principles behind teaching math and reading, most of which are embedded within various curricula. As a new teacher, I had to figure out what to do when there is no curriculum. The solution? I found that sometimes you can wing it using a combination of resources from other teachers, pieces of vetted curriculum, and your own knowledge. You can also search for free programs online (such as the Engage NY math program). You make it work, but no grad school class can prepare you for a lack of resources! 2. Bodily Issues There are zero things that can prepare you for a child throwing up all over herself, her desk, and the floor 10 minutes into your math lesson the day after a vacation. Similarly, nothing in a book prepares you for when a kid gets a bloody nose so bad he drips all over the rug. Additionally, no one warns you about kids having accidents, or breaking a leg and being unable to get up the stairs in your elevator-less building from 150 years ago. In short: things happen. Sometimes all you can do is laugh (after the vomit has been cleaned up) and know that there will be new challenges tomorrow! 3. Parents The most difficult experiences Iâ?ve had teaching have been with parents. I signed up to be a teacher to work with kids â? not adults â? but with kids come their parents. One of the most valuable lessons I have learned is that it is always, always, always better to communicate via phone or in person rather than email. If you have even the slightest hesitation of how something could be construed, do not put it in an email. If it is a tough conversation you know will elicit emotion, do not put it in an email. Conclusion: voice, tone, body language, and emotion are best conveyed in-person or on the phone. 4. Behavioral Issues Behavior is one of the hardest issues to deal with in the classroom because while you can discuss the subject in theory for hours on end, the reality is often a completely different story. Sometimes, a student will refuse to leave the room for a specialist. Maybe he will rip up his test after completing it because the last question is too hard. Or how about deleting all of his reading and writing folders on his Chromebook so none of the work is recoverable? Often, there are behavior issues among children at unstructured times of the day, such as lunch or recess, where you as the teacher may not be physically present. What Iâ?ve found helpful is to be proactive rather than reactive. Create a strong classroom culture and feelings of trust, respect, and community among your students. Take the time to get to know them as individuals and let them know that you care about them. Talk with them and let them talk to you when they need to. Care and love go a very long way in the classroom. Teaching is the greatest thing I have ever done in my life and not a day goes by that anything truly goes according to plan, but thatâ?s part of what makes it so exhilarating. I have learned more in the four years of teaching than ever before in my life â? about human nature, anxiety, love, and fear â? and wouldnâ?t trade it for anything. Remain patient, calm, and look at issues through multiple perspectives. Know that you arenâ?t in it alone and there is always someone to give you advice when you arenâ?t sure. The final, best piece of advice a coworker ever gave me: fake it til you make it!   What do you wish you had learned in grad school? Share with us on Instagram, Facebook, Twitter, and Pinterest.

John Ross And Mill s Utilitarianism And Ross Essay

Introduction: Mill s Utilitarianism and Ross Intuitionalism both use moral intuitions as core components of their moral theories, though their valuation of these intuition in making morally sound decisions differ. I will argue that it is this mis-valuation of moral intuition in Utilitarian tradition that makes the moral theory unstable and prone to criticism. Ross deontological approach to moral intuitions provides a more believable, and morally acceptable account of the role these intuitions play in making ethical decisions. In this paper I will begin with underlying both Ross and Mill s valuation of moral intuitions in the framework of their moral theories, followed by a brief explanation of each philosophers view of â€Å"what makes an act moral†. Having established these I will, with the aid of an anecdote about a child and a sled, describe my difficulties with Mill s utilitarian approach to ethics. Finishing with an assessment of some utilitarian complaints about Ross theory. Ultimately Utilitarianism provides a commendable theory for widely applicable and practical moral action, but it s inability to address conflicts with strong moral intuitions weakens it s argument leading me to favor that of Ross more flexible, yet not relativistic, intuitionalism. i) The Value of Moral Intuitions: Both Ross and Mill recognize the existence of what one might call a â€Å"prima facie† duty ( or virtue), this being an action that is intuitively deemed morally rightShow MoreRelatedJohn Ross And Mill s Utilitarianism And Ross Essay1926 Words   |  8 PagesIntroduction: Mill s Utilitarianism and Ross Intuitionalism both use moral intuitions as core components of their moral theories, but their valuation of these intuitions in making morally sound decisions differ.

Renewable Forms of Energy Wind Energy Essay - 1320 Words

Renewable forms of energy are becoming more and more necessary for a sustainable future. Wind energy is a form of energy that is becoming more and more popular, and it offers a way for people to harness energy from something natural to create electricity. Wind energy in addition to other sustainable forms of creating energy are going to start taking the place of fossil fuels as people realize the true benefits of using them. There are many benefits of using wind energy in comparison to using fossil fuels. The first is that once wind turbines are built, they don’t release greenhouse gasses into the atmosphere. Wind energy also doesn’t pollute the air or water with other pollutants. Of course some greenhouse gasses and other pollutants†¦show more content†¦Coal costs 3.14 cents per kilowatt-hour (Pare); this cost includes the capital cost, operating and maintenance costs, and the price of the coal itself (Pare). Natural gas on the other hand costs 4.95per kilowat t-hour (Pare); this cost includes the capital cost, operating and maintenance costs, and the price of the gas itself (Pare). Wind energy costs 3.14 cents per kilowatt-hour this includes the capital costs and operating costs, but wind itself is free, so there is no cost for the source of energy (Pare). Based on the direct costs, wind energy is the same price as coal and cheaper than the cost of natural gas (Pare). If the indirect costs such as health and climate change are also incorporated into the total cost of the forms of energy, the price of natural gas rises to 8.09 cents per kilowatt-hour and coal rises to 10.29 cents per kilowatt-hour (Pare). The only indirect costs of wind power are that they aren’t exactly visually attractive to many people, and they can kill birds. These indirect costs of wind energy can’t accurately be quantified therefore the total price of wind energy remains at 3.14 cents per kilowatt-hour, making wind energy cheaper than both natural gas and coal when all costs are compared (Pare). Below is a chart representing the cost of these energy sources. One problem with wind energy is its consistency. Wind speeds are constantly changing.

Introduction In the field of management, motivating employees is a very important issue that managers have to consider. Research has shown in many cases that companies with motivated and satisfied employees are more efficient and productive. We will write a custom essay sample on Maslow’s Hierarchy of Needs or any similar topic only for you Order Now Considering the goal of the company, this can lead to higher profits and moreover to a good internal corporate culture. How can managers accomplish this task? Is it effective using Maslow’s theory to motivate employees? This paper will analyze why managers should not follow Maslow’s theory of needs in order to motivate employees. To prove this statement, the expose will focus on the model of Maslow’s hierarchy of needs, after giving a brief description of motivation. In addition the paper will examine how, according to Maslow, managers can satisfy these needs in a company. Furthermore the weaknesses are pointed out, also with the help of research studies. At the end, Alderfer’s ERG Theory is compared to Maslow’s theory , as he reshaped the hierarchy of needs, which will provide a better understanding of Maslow’s theory and especially of the weaknesses. Although Maslow’s theory is often used to illustrate the concept of motivation, it is not a reliable theory when utilizing it in practice. 2. Motivation In the context of Psychology motivation can be described as ‘ processes that account for an individual’s intensity, direction, and persistence of effort toward attaining a goal ‘(Robbins 2007: 186). Many managers who do not see motivation in their employees tend to characterize them as lazy. However motivation is not a personal trait, and therefore can always be taught. This concludes that one should not deal with the question whether someone is motivated, instead one should find out what is causing the motivation or lack of motivation (Robbins 2007: 186) In the 1950’s some of the first need theories that explain how work-related behavior can be driven by satisfying needs, were formulated (Furnham 1992: 128). 3. Maslow’s Hierarchy of Needs The need hierarchy which is also associated with a pyramid , is divided into five levels which represent five basic needs. Maslow assumed that an individual had five needs which are activated in a hierarchical order. It was based on the prepotency of needs, meaning that a need emerged as a motivator as soon as a lower-need was satisfied (Heylighen 1992: 40) 3. 1 Model * Physiological Needs – food, water , air , shelter * Safety Needs – security, stability, protection * Love and Belongingness Needs– relationships, friends, family, socializing * Self-esteem Needs – achievement, reputation, independence, prestige * Self-actualization Needs – becoming everything one is capable of becoming (Maslow 1970 : 39-46) Counter argument: Maslow’s theory claims that all needs are not equal. In general, one might approve this statement as in many cases lower order needs take priority over higher order needs. However, in certain situations e. g escaping danger, hunger might be unimportant (Kalat 2008: 377). Therefore the hierarchical model does not provide an accurate picture of reality and does not consider these exceptions. 3. 2 Application on Management As Maslow claims, that once a need is satisfied, it does not serve as a motivator anymore, managers for example cannot only pay their employees more money, as this need will eventually be satisfied and no longer be a motivator. Instead they have to find other ways to satisfy the different needs (Robbins: 187) In the context of an organization (Sadri 2011 : 45-48) : * Physiological Needs – salaries, wages, bonuses * Safety Needs – health insurances, retirement plans * Love and Belongingness Needs – teamwork, company festivals, clubs * Self-esteem Needs –recognition, praise, competitions, promotions * Self-actualization Needs- tution reimbursement programs Counter argument: Maslow argues that a ‘satisfied need no longer motivates’. (Robbins 2007: 187). However, due to the fact that ‘ motivation is driven by the situation’ (Robbins 2007: 186) , for an employee who has reached self-esteem, job security can become a motivator again, in times of a financial crisis. 3. 3 Weaknesses * Motivation does not change only within an individual due to different situations, but also among all individuals (Robbins 2007: 186). Therefore managers have to know how to motivate each employee in an effective way according to Maslow. This is a big challenge, and unlikely to occur when implementing in reality. Another criticism of the theory itself is the aspect of culture. ‘ In countries like Japan, Greece, and Mexico, where uncertainty avoidance characteristics are strong, security needs would be on top of the need hierarchy’ (Robbins 2007: 212). This shows that the theory can only be applied to the American culture, where self-actualization is the goal of most individuals. * From 1966 to 1973, there have been many studies, whi ch tested Maslow’s theory, however ‘these results were not supportive of Maslow’s need structure (Wahba,Bridwell 1976)’ (Berl, Williamson Powell 1984: 34). 4. ERG Theory Clayton Alderfer, an american psychologist reworked Maslow’s hierarchy of needs and developed a theory called ERG Theory (Robbins 2007: 188) 4. 1 Comparison to Maslow’s Theory In comparison to Maslow, Alderfer distinguishes between three categories (Weihrich 2010: 331). * Existence Needs * Relatedness Needs * Growth Needs Alderfer criticised the hierarchic order, giving two reasons. * Firstly ,through the hierarchic order only one need can be satisfied at a time. Alderfer referred to this point in his theory, and affirmed that ‘ more than one need may be activated at a time’ (Kreitner 2007 : 238). For example, an employee might go to work in order to afford a place to live, but also because he or she is motivated due to the good relationships with coworkers or managers (Weihrich 2010: 331-332). * On top of that Maslow justified his hierarchic order with the belief that ‘people tend to satisfy their needs systematically’ (Cole 2004: 36). However Alderfer argued that a ‘systematic movement up the hierarchy does not seem to be a consistent form of behavior for many people’ (Cole 2004: 36). 5. Conclusion The examination of Maslow’s theory and the comparison to Alderfer’s theory lead to the conclusion that on one side, it is true that individuals have different needs and that they relate to work behavior, but unfortunately the hierarchic structure does not appropriately reflect reality. On top of that, it is impossible for managers to find out what need is dominating each employee, as it can change due to situations. Furthermore ,due to the aspect of culture you cannot place a specific need at the top. As the weaknesses supported by the research, prove that the model does not work out in practice, it can be concluded that it is not advisable for managers to follow Maslow’s hierarchy of needs in order to motivate employees.

Timeline of Greek and Roman Philosophers

Timeline of Greek and Roman Philosophers What was the first cause of our existence? What is real? What is the purpose of our lives? Questions like these have become the basis of the study known as philosophy. While these questions were addressed in ancient times through religion, the process of logically and methodically thinking through lifes big questions did not begin until about the 7th century BCE. As different groups of philosophers worked together, they developed schools or approaches to philosophy. These schools described the origins and purpose of existence in very different ways. Individual philosophers within each school had their own particular ideas. The Pre-Socratic philosophers are the earliest of the philosophers. Their concern was not so much with the topics of ethics and knowledge that modern people associate with philosophy, but concepts we might associate with physics.  Empedocles and Anaxagoras are counted as Pluralists, who believed there is more than one basic element from which everything is composed. Leucippus and Democritus are Atomists. More or less following the Pre-Socratics came the trio of Socrates-Plato-Aristotle, the schools of the Cynics, Skeptics, Stoics, and Epicureans. The Milesian School: 7th-6th Centuries BCE Miletus was an ancient Greek Ionian city-state on the western coast of Asia Minor in today’s Turkey. The Milesian School consisted of Thales, Anaximander, and Anaximenes (all from Miletus). The three are sometimes described as materialists, because they believed that all things derived from a single material. Thales (636-546 BCE): Thales was certainly a real historical individual, but very little evidence remains of his work or writing. He believed that the first cause of all things was water, and may have written two treatises entitled On the Solstice and On the Equinox, focusing on his astronomical observation. He may also have developed several significant mathematical theorems. It is likely that his work strongly influenced Aristotle and Plato.Anaximander (c.611-c.547 BCE): Unlike Thales, his mentor, Anaximander actually wrote materials can be credited to his name. Like Thales, he believed that just one material was the source of all thingsbut Anaximander called that one thing the boundless or infinite. His ideas may well have strongly influenced Plato.Anaximenes (d. c. 502 BCE): Anaximenes may well have been a student of Anaximander. Like the other two Milesians, Anaximenes believed that a single substance was the source of all things. His choice for that substance was the air. Accor ding to Anaximenes, when the air becomes finer, it becomes fire, when it is condensed, it becomes first wind, then cloud, then water, then earth, then stone. The Eleatic School: 6th and 5th centuries BCE Xenophanes, Parmenides, and Zeno of Elea were members of the Eleatic School (named for its location in Elea, a Greek colony in southern Italy). They rejected the idea of many gods and questioned the idea that there is one reality. Xenophanes of Colophon (c. 570-480 BCE): Xenophanes rejected the anthropomorphic deities and considered there to be one incorporeal god. Xenophanes may have asserted that men may have beliefs, but they dont have certain knowledge.Parmenides of Elea (c. 515-c. 445 BCE): Parmenides believed that nothing comes into being because everything must derive from something that already exists.Zeno of Elea, (c. 490-c. 430 BCE): Zeno of Elea (in southern Italy) was known for his intriguing puzzles and paradoxes. Pre-Socratic and Socratic Philosophers of the 6th and 5th Centuries BCE Anaxagoras of Clazomenae(c. 499-c. 428)Greek philosopherProtagoras(480-411)Greek philosopher SophistSocrates(c. 469-399)Greek philosopherPlato(c. 427-347)Greek philosopherDiogenes of Sinope(412-323)Greek philosopher Philosophers of the 4th Century BCE Aristotle(384-322)Greek philosopherEpicurus(341-271)Greek philosopherEuclid(c. 325-265)Greek mathematicianAristarchos(c. 310-250)Greek astronomer Philosophers of the 3rd Century BCE Chrysippus(c. 280-207)Hellenistic philosopherEratosthenes(276-194)Hellenistic astronomer Philosophers of the 2nd Century BCE Panaetius(c. 185-110)Stoic and Neo-Platonic PhilosopherLucretius(c. 98-55)Roman poet and Epicurean philosopher Philosophers of the 1st Century CE Epictetus(50 - 138)Roman philosopherMarcus Aurelius(121-180)Roman emperor and philosopher Philosophers of the 3rd Century CE Plotinus(c. 204-270)Greco-roman philosopher Philosophers of the 4th Century CE Hypatia of Alexandria(c. 370-415)Alexandrian philosopher Philosophers of the 4th Century CE Boethius(480-525)Philosopher and Christian martyr who was called the last of the Romans.

Capitalization Rules for Names of Historical Periods and Movements

Capitalization Rules for Names of Historical Periods and Movements Capitalization Rules for Names of Historical Periods and Movements Capitalization Rules for Names of Historical Periods and Movements By Mark Nichol When are designations for historically significant phenomena treated with initial capital letters, and when are the names rendered with lowercase letters? Exceptions, as always, are available to confound us, but the rules are fairly straightforward. Names of political and cultural periods or events are often capitalized in their original connotations, but when such nomenclature is used by extension in a generic sense, the designations are (usually) lowercased. For example, one should write, for example, â€Å"The arts and sciences flourished during the Renaissance,† but â€Å"The downtown district is experiencing a renaissance.† (However, to describe someone as well rounded in skills or talents, write â€Å"He’s a Renaissance man† even when he is not a contemporary of Michelangelo.) The same distinction applies for such terms as â€Å"golden age† (â€Å"The Golden Age was the first of Hesiod’s Ages of Man,† but â€Å"Jazz music has experienced several golden ages†) and â€Å"belle à ©poque† (â€Å"The period of peace and optimism in France in the nearly half century before World War I came to be known retrospectively as the Belle Époque,† but â€Å"They look back on that prosperous period as a belle à ©poque†). Similarly, one would write â€Å"China’s infamous Cultural Revolution was a decade-long time of great turmoil,† but â€Å"American society has undergone a cultural revolution of late,† and while references to the mid-twentieth-century tension between Western nations and the Communist Bloc capitalize â€Å"Cold War,† any such conflict without open hostilities is a cold war. The Enlightenment was a specific cultural movement in Europe and Britain’s American colonies during the 1600s and 1700s, or a similar era in any one of several countries. Generic usage is as follows: â€Å"In the Western world, the concept of enlightenment in a religious context acquired a romantic meaning.† However, in specific usage, enlightenment is capitalized: â€Å"The Russian Enlightenment is a period in the eighteenth century in which the government in Russia began to actively encourage the proliferation of arts and sciences.† Adjectives preceding names of political entities are often erroneously capitalized. No civilization has ever gone by the official name of Ancient Greece or Imperial Rome, for example; the first word in such designations is generally a mere descriptor and is therefore lowercased: â€Å"The course is a general overview of the history of ancient Greece†; â€Å"This essay will discuss the economic structure of imperial Rome.† Want to improve your English in five minutes a day?

Chlamydia Research Paper Example | Topics and Well Written Essays - 1000 words

Chlamydia - Research Paper Example In addition, it affects both men and women. Additionally, about 30 to 50 percent of the women in the United States have been exposed to the bacterium at one point in their life. Additionally, Chlamydia ascends to the upper genital tract if left untreated in about 40 percent of the cases. As a result, C. trachomatis is known to be one of the major causes of acquired infertility. Generally, due to the high prevalence and adverse complication of untreated infections Chlamydia remains a major public health problem in industrialized countries (Dean, et al., 2009). As aforementioned, Chlamydia is transmitted from one individual to another through oral and sexual contact. Penetrative sexual intercourse is the primary mode of transmission. Chlamydia is transmitted through the vagina, anus, and oral sexual intercourse with an disease-ridden partner (Malhotra, Sood, Mukherjee, Muralidhar, & Bala, 2013). Infected individuals are the reservoirs of the infection. According to Breguet (2006), Mother to Child Transmission (MCT) can occur during vaginal delivery. In addition, conjunctivitis can occur on the occasion that a person touches his or her eyes with infected hands. The infections occur in the urethra, cervix, throat, rectum, eyes, throat, penis, and cervix (Breguet, 2006). According to the CDC (2007), a quarter of the females infected and half of the males do not present with any symptoms. In this regard, it is referred to as the ‘silent’ disease. However, in the population that presents with symptoms, they usually occur within 1 to 3 weeks after infection. Additionally, the symptoms tend to present differently in both men and women. The urethra and the cervix are the major organs affected in women. After an infection, women present with symptoms such as abnormal vaginal discharge and pain when passing urine. An infection of the cervix and fallopian tubes is characterized by symptoms such as pain during copulation, abnormal vaginal bleeding, abdominal pain,

State and Society in 20th Century China Essay Example | Topics and Well Written Essays - 2000 words

State and Society in 20th Century China - Essay Example The consumer-centric trading model has also helped China bring down the increasing currency exchange rates, which had caused great uproars in international financial domains, particularly during the recent economic recessions. It may be noted that the Chinese society espoused consumerism with regard to currency exchange rates, amendments in property ownership acts, and de-institutionalisation of political authority over various prefectures. It is quite logical to state that such a shift in socio-economic spheres has not been an easy ride. The erstwhile communist austerity gave way to broader perspectives in all walks of life in China. Most notably, the emerging middle-class segment of the country has been able to find jobs in private sectors, but at the cost of state-owned jobs. This downsizing in state firms has implicit connection with the drooping economic conditions around the world. Standard societal structures in China have faced major challenges in sustaining the development programs the scope of which has been increasing everyday as the country is attracting more and more foreign direct investments in the economic upfront. Urbanization too has posed problems for the otherwise bureaucratic state mechanism to effectively control massive intra-country migrations (Lieberthal). Under these circumstances, China has been the center of global affairs, for better or worse, in the last few years. This paper is going to d iscuss the difficulties faced by the current Chinese leadership in dealing with issues of national interest. The study will also take into consideration how well the Chinese government is adept at handling such issues. Given the sheer geographical vastness of the land, it is quite apparent that the reformist means undertaken by the Chinese political regime face serious societal and economic challenges. Moreover, there is

Inleiding :: German Essays

Inleiding Door de druk van de publieke opinie gaan bedrijven steeds vaker rekening houden met hun omgeving. Onder deze omgeving verstaan wij niet alleen mensen die in de nabijheid van deze bedrijven wonen, maar ook het personeel en het milieu. De samenleving eist van bedrijven dat ze minder vervuilend worden en vooral ook ‘veiliger’. De overheid vertaalt deze eisen in een kader wetgeving die aangeeft aan welke eisen bedrijven moeten voldoen. De bedrijven die op het moment van het ontstaan van kaderwetgeving nog geen maatregelingen hebben getroffen om te voldoen aan de eisen worden vaak opgezadeld met hoge kosten die doorberekend worden in het product. Vervolgens blijkt echter dat de consument niet bereid is om meer te betalen voor een product. De gevolgen van deze neerwaartse spiraal laten zich raden en hebben ervoor gezorgd dat vooraanstaande strategen zich gebogen hebben over dit probleem. Zij komen over het algemeen tot de conclusie dat bedrijven door een innovatief (milie u) beleid te voeren voordelen kunnen behalen ten op zichtte van de concurrentie. Dit beleid moet een vooruitziende blik hebben in de richting van toekomstige eisen zodat op een vroeg moment maatregelen kunnen worden getroffen. Vaak blijken bedrijven hierdoor effectiever en efficià «nter te gaan werken waardoor de productiekosten vaak zelfs gaan dalen in plaats van stijgen. In jaar drie van de studie bedrijfskunde gaan wij voor het vak operationeel beheer een onderzoek uitvoeren binnen het kader van drie zorgsystemen. Deze zorgsystemen zijn veiligheids-, milieu- en kwaliteitssystemen. Het bewustzijn dat kwaliteitssystemen grote voordelen met zich meebrengen is rond 1980 ontstaan1. Dit bewustzijn heeft zich ontwikkeld tot de huidige vorm van kwaliteitsmanagement. De ervaringen die hiermee zijn opgedaan kunnen gebruikt worden om toe te passen op de milieu- en veiligheidssystemen. Wij gaan proberen deze vertaalslag te maken. Dit onderzoek zal tevens aan de praktijk getoetst worden door DSM in het onderzoek te betrekken. De theoretische leidraad in ons onderzoek komt voor het grootste gedeelte uit het verplichte studiemateriaal benodigd voor het vak operationeel beheer. De basis voor onze probleemstelling en de daaruit afgeleide vraagstelling komt uit het artikel van M.E. Porter en C. van der Linde, Green and Competitive. Hierin wordt gesteld dat bedr ijven die een innovatief milieu beleid hanteren productiever worden en daardoor beter kunnen concurreren. Er wordt in dit artikel gesteld dat bedrijven te weinig kijken naar de voordelen die een innovatief milieubeleid met zich mee brengt en teveel kijken naar de statische kosten.

Physics, Energy

Romar M. Cabinta EXERCISES 15 WORK, ENERGY, AND POWER A. CONCEPTUAL QUESTIONS 1. Is work done when you move a book from the top of the desk to the floor? Why? Yes. It is because the displacement of the book from the top of the desk to the floor and the force that is applied to the book is parallel with one another. 2. State the law of Conservation of Mechanical Energy in two ways? The law of conservation of energy states that energy may neither be created nor destroyed. Therefore the sum of all the energies in the system is a constant. TMEinitial=TMEfinal 3. Explain the basic ideas that govern the design and operation of a roller coaster.A roller coaster is operated and designed through the application of Physics. The law of Conservation of Energy governs the changes in a coaster's speed and height. Simply put, the higher an object is off the ground, the more potential energy it has – that is, potential to gain speed as it falls. As it falls toward the ground, that potential e nergy changes to kinetic energy, or energy of motion. The sum of the two types of energy is constant, but a roller coaster must maintain an adequate balance of potential and kinetic energies to deliver a thrilling ride. . An inefficient machine is said to â€Å"waste energy†. Does this mean that energy is actually lost? Explain. Energy is never lost. An inefficient machine wastes energy by converting it to an unproductive state. A machine, such as a motor car engine has the primary task of converting the energy in the fuel to motion of the car. It is unproductive because a large proportion of the fuel's chemical energy is dissipated in the form of noise, heat, vibration etc. so that only a small proportion is actually used for its prime purpose. 5.Is it possible for a simple machine to multiply both force and speed at the same time? Why? It is impossible for a simple machine to multiply both force and gain speed at the same time. It is because the gain in speed of a machine i s the result of an exertion of a lot more force and therefore do not take place at the same time. One best example is a bicycle crossing a steep hill requires a greater force to be exerted to be able to gain speed. B. PROBLEMS 1. Starting from rest, 5-kg slides 2. 5 m down a rough 30 ° incline.

CONCEPTUAL QUESTIONS 1. Which has greater momentum, a ten wheeler truck at rest or a moving motorcycle? Why? A moving motorcycle has a greater momentum than the truck. A truck at rest has zero momentum because an object has to be moving in order to have a momentum. 2. How does impulse differ from force? Impulse is the product of force and the time interval of the application of force; while force is just a factor that affects an object’s impulse when it is at motion. 3.Why is it incorrect to say that impulse equals momentum? It is not right to say that impulse is equal to momentum because impulse is the measure of the change in momentum and therefore an object with constant and non-changing momentum has zero impulse. 4. What is the function of seatbelts and airbags in automobile? The function of seatbelts and airbags in an automobile is to increase the time of a force to reach its destination, which results to a lesser impact of objects that can collide to a passenger and therefore will have a higher chance for his/her life to be saved. 5. Distinguish between an elastic collision and inelastic collision.In elastic collision, the momentum and the kinetic energy are conserved; and its coefficient of restitution is equal to one. However in inelastic collision, the kinetic energy is not conserved and the coefficient of restitution is zero. B. PROBLEMS 1. A 10,000-kg truck has a speed of 100 km/h? (a) what is its momentum? What speed must a 5,000-kg truck attain in order to have (b) the same momentum?

CONCEPTUAL QUESTIONS 1. What is Hooke’s Law? Hooke's law  of  elasticity  is an approximation that states that the extension of a spring is in direct proportion with the  load  applied to it. Many materials obey this law as long as the load does not exceed the material's  elastic limit. Materials for which Hooke's law is a useful approximation are known as  linear-elastic  or â€Å"Hookean† materials. Hookean materials are a necessarily broad term that may include the work of muscular layers of the heart.Hooke's law in simple terms says that  stress  is  directly proportional  to  strain. Mathematically, Hooke's law states that 2. When is a material said to be elastic? A mate rial is called elastic if the deformation produced in the body is completely recovered after the removal the load. For ideally elastic materials, a single valued (linear) and time independent relation exists between the forces and the deformations. Although it is hard to find an ideally elastic material, i. e. , A Hookean solid, most of the materials can be considered elastic at least for a specific range. 3.Which is more elastic, a rubber band or spiral steel spring? Why? Spiral steel spring is more elastic than rubber band because it has greater elastic limit and ultimate strength than a rubber band because it has greater elastic limit and ultimate strength than a rubber. 4. What is the difference between the elastic limit of a material and its ultimate strength? Why are these concepts of special importance to construction engineers? Elastic limit is the maximum stress that can be applied to a material without being permanently deformed while ultimate strength is the stress requir ed to cause actual fracture to a material.These concepts are important to construction engineers because it gives them the idea of what materials are perfect for the construction and those that are fragile. 5. Which is more compressible, alcohol or water? Why? Alcohol. It is because alcohol has higher compressibility and accepts a greater pressure than on water. B. PROBLEMS 1.

Stem Cell Research - 872 Words

Rendering itself as a basic unit of growth and development, stem cells are essential in early life. They are small, unspecialized cells capable of reproducing and differentiating into different cell types. These cells can turn into a functional cell such as a muscle cell, organ-specific cell, brain cell, or a red blood cell. Despite controversy, stem cell research has given life back to suffering individuals and brought hope to the medical field. Along side many other major advancements of biology in the last century, stem cell research has taken off and found tremendous success just in the last fifteen years. In 1981 embryonic stem cells were first isolated from early mice embryos by American Biologists. By1986, scientist became familiar with mice stem cells and soon reports arose of successful attempts of converting mice fibroblasts into myoblasts by using only a single gene. Proving evidence that it is possible to convert one type of adult cell into another. Finally, by 1998, a re search team from the University of Wisconsin reported the first successful formation of human embryonic stem cells derived from early embryonic cells. This research was the first to demonstrate that it was possible for human stem cells to be manipulated and differentiated. Since the authorization in 2001 by President Bush to grant federal funding for research of stem cell lines, there has been a medical breakthrough in the use of human stem cells.
