Analysis Christina Aguileras Beautiful Essay - 1367 Words
Artists use music videoââ¬â¢s to visually show the meaning behind of the song and how they want it to be portrayed. Some music videoââ¬â¢s use socio-cultural codes to construct the visual narrative and structure of their work. For example the music video of Christina Aguileraââ¬â¢s song ââ¬ËBeautifulââ¬â¢, ââ¬Ëpacked with a message of holding oneââ¬â¢s self up against criticism from the outside.ââ¬â¢Ã ¹, shows the insecurities people have with what society portrays to be beautiful. Such as showing characters throughout the video struggling with body image, sexual preference and bullying. The characters develop throughout the video, showing that they accept themselves for who they are and understand the meaning of inner beauty. Music videos are created for multipleâ⬠¦show more contentâ⬠¦At the end of the music video it shows the young girl breaking the mirror as she punches it through, as if saying that she doesnââ¬â¢t want to be anorexic anymore. It also shows the young boy looking in his bathroom mirror, showing that his body shape had changed slightly. A smile then came across his face, being happy with what he sees. These sequences show how the characters struggled with their body image and how they saw themselves and what they believe they should look like to fit in with society and their peers, but also how they came to accept themselves for who they are. The video continues to show other sequences of other characters, showing examples of socio-cultural codes such as problems with self-esteem and what society portrays to be beautiful, as well as bullying. The music video shows a young African- American girl ripping out pages of a magazine showing only white models.

Physics Friction Lab Free Essays
Friction Page 1 Lab: Friction William Morris Leo Hayes High School Friction Page 2 Purpose: To investigate the coefficient of friction for a given surface and the effects that factors such as weight, surface area and changes to the surface have on the coefficient of friction. Hypothesis: The smaller the amount of normal force (weight), the less friction created and the least surface area and the greaser the surface the less friction is created. With the increase in normal force corresponding with the increase in friction should balance out ââ¬Å"muâ⬠. We will write a custom essay sample on Physics Friction Lab or any similar topic only for you Order Now Materials: Spring scale, string, 4 textbooks, Pledge Procedure: 1. Using a spring scale and some string we hooked through the pages of the text book to find the weight to find the weight of each text book we used and then recorded it. 2. We pulled the first text book across the table then estimated the amount of force we needed to apply to the scale attached to the text book to move it at a constant speed and then recorded our guess. 3. Using the string and spring scale we pulled the text book across the table at a constant speed keeping the string parallel to the surface of the table and then recorded the data. . From this measured force below, we determined the frictional force that had acted upon the book as we pulled it across the table. 5. Then we pulled the book across the table once more at a different constant speed to ensure accurate friction readings. 6. From the weights of the text book we found earlier we determined the normal force acting on the text book as we pulled it across the table and then recorded it below. 7. We a dded the second text book, (B), to the first one and pulled them across the table again recording their force of friction. 8. We then repeated this procedure twice more adding a text book each time as recorded below. 9. We then pulled text book, A, on its spine across the table at a constant speed recording the force from the scale. 10. We pledged the table and rubbed it thoroughly with a cloth and then repeated only step 3 on this pledged surface and recorded the force required. Friction Page 3 Questions: 1. Compare the books weight with the force required to pull it horizontally at a constant speed. Which one is larger? In all cases the normal force is larger than the force of friction. 2. It always takes more force to start an object than to keep it moving at a constant speed. Why? Friction is caused by tiny scratches in the smoothness of a surface. The rougher a surface is, the rougher it feels. And the rougher a pair of surfaces are, the harder it is for them to slide past each other. The tiny rough edges grab hold of each other and lock the surfaces into place, so that it takes a great deal of force to make them move. Thatââ¬â¢s the static friction youââ¬â¢re trying to overcome. Once you get the surfaces moving the rough edges are already dislodged and as long as you donââ¬â¢t stop, they wonââ¬â¢t have a chance to lock again. Therefore, itââ¬â¢s easier to keep something moving once youââ¬â¢ve started than it would be to stop and start again. 3. Does it take more force to move an object at a higher constant speed than a slower constant speed? In our lab the force seemed to stay the same. This could have something to do with our sources of error. The lab did not reveal this. 4. The force of friction was found in part 3. Would it be more or less if you pulled the text book across: (a) Ice(b) Sand(c) Rough Concrete(d) Waxed Floor How is the force of friction affected by changing the surface from smooth to rough? a) Less friction (b) More friction (c) More friction (d) More friction A rough surface has more grooves to grab than a smooth surface therefore creating more friction. Friction Page 4 5. Does the force of friction depend on the speed of motion? In our lab it was impossible to figure this out due to our sources of error. 6. Write an equation showing the relationship between the force of friction and the normal force. Use this equation to calculate the coefficient of friction for each set of readings. 7. What are the units for ââ¬Å"muâ⬠, the coefficient of friction? There is no unit measurement for the coefficient of friction. 8. Plot a full page graph of the force of friction verse the normal force. See graph on following page for the force of friction verse the normal force. 9. Based on your graph what is the relationship between the coefficient of friction verse the normal force. The relationship between the coefficient of friction verse the normal force is such that the coefficient is the same because the increase in normal force corresponds with the then increase in friction creating the same ââ¬Å"muâ⬠. 10. How do the coefficients of friction compare for each of your five trials in the data table? Is this how they should be? With a smoother surface the friction is lowered therefore lowering ââ¬Å"muâ⬠. This is how it should be. Friction Page 5 Data/Results: Books| Normal Force| Friction| à µ| A| 10. 5 N| 2. 5 N| 0. 24| A + B| 20. 5 N| 5. 0 N| 0. 24| A + B + C| 31. 5 N| 7. 5 N| 0. 24| A + B + C + D| 42. 5 N| 10. 0 N| 0. 24| Book A on spine| 10. 5 N| 2. 0 N| 0. 20| Books A on Pledged Surface| 10. 5 N| 2. 0 N| 0. 20| Books| Normal Force (weight)| A| 10. 5 N| B| 10. 0 N| C| 11. 0 N| D| 11. 0 N| Discussion: There are several sources of error in this lab. One being the scales not being accurate and there is no way to fix this except to purchase new scales each time. Another could be the angle we are pulling the book from. There is no way for us to be exactly sure if this force is exactly parallel with the table. When finding our normal force we do not take into consideration the weight of the string and this cannot be fixed as our scales are not this precise. It is unknown if our hand was completely steady while finding our normal force. This could result in our normal force being inaccurate. There is no way to fix this as we are not robots. The same is true for finding the force of friction as we are not sure we are pulling the book(s) at the same constant speed. Conclusion: After the lab I found my hypothesis to be true in that the smaller the amount of normal force (weight), the less friction created and the least surface area and the greaser the surface the less friction was created. With the increase in normal force corresponding with the increase in friction it balanced out ââ¬Å"muâ⬠. How to cite Physics Friction Lab, Essay examples

Workplace Inequalities free essay sample
Every person has the right to be fairly treated in their daily lives and the workplace is no exception. Discrimination in the workforce has always been a well debated topic. Throughout history many different groups have faced inequalities in the workplace, and over time, with the changes in social views, different measures have been undertaken, by the different levels involved in employment, to eradicate these adversities. Unfortunately inequality during employment is still a major crisis for many people. This essay looks at three different groups facing difficulty in the workplace due too discrimination and the response by government, unions, employers and other groups to these inequalities. Pregnant women in the workforce have always been a delicate topic. With recent legislation changes and advances in ââ¬Ëpregnancy in the workforceââ¬â¢ campaigns, the inequality faced by many women who fall pregnant while under employment has begun to change, however, many lobbyists believe that employers are still not doing enough to protect their employees rights during such a serious time in a womenââ¬â¢s life. We will write a custom essay sample on Workplace Inequalities or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Teenagersââ¬â¢ entering the workforce has also become a serious topic. During such a pivotal time in a young teenagers life, with school and social activities, young people can often face inequalities in their employment and without prior knowledge of the workforce, can often be unknowingly subjected to mistreatment. On the other end of the timeline, aged workers are often subject to unfair treatment and ridicule from their employers and co-workers. In an increasingly aging country, Australia has had to bring age discrimination to the forefront of workplace reform. Although discrimination and inequalities in the workplace are constantly being discouraged and sought out, most people will feel mistreated in the workplace at some point in their working lives. The Australian Government, unions and employers are constantly working towards better equality for employees in the workforce. Many different initiatives have been put in place to stamp out workplace discrimination and these groups will continue to work towards better rights for workers. Pregnancy is an incredibly important time for those involved. Women face a vast range of emotional stress when dealing with a pregnancy and many women have to continue working during much of their pregnancy to cope with the coming financial burden of raising a new born child. Around 80% of women in Australia are employed prior to the birth of their first child [1]. With the known risk of emotional stress on womenââ¬â¢s pregnancy, limiting stress in the workplace is serious priority for employers. Unfortunately recent studies into the subject have found that ââ¬Å"pregnancy-related workplace discrimination (in Australia) is disturbingly prevalentâ⬠[2]. A University of Melbourne study into the entitlements of workers during pregnancy and the psychological welfare of pregnant women in the workplace, found that, of the 165 employed pregnant women surveyed; ? Despite current legislation requiring all Australian employees to have access to unpaid maternity leave after 12 months of continuous employment, only 60% had the option. ?Only 46% had access to paid maternity leave, forcing others to rely on sick or annual leave or forego income after childbirth. Almost one in five women claimed pregnancy-related discrimination in the form of negative or offensive comments as well as being excluded from promotion or training by their employer [3]. Many groups are outraged at this unfair treatment for pregnant women during employment. Considering the severity of the occasion, a pregnant womanââ¬â¢s health and wellbeing should be of great concern to an employer. The government has sought to stem this trend of discrimination with current legislat ion protecting pregnant women from unfair treatment in the workforce. EOWA, the Equal Opportunity for Women in the Workplace Agency, is a government agency aimed at achieving equal opportunity for women in the workforce through the administration of the Equal Opportunity for Women in the Workplace Act 1999 [4]. Many lobbyists believe that all women should have access to paid maternity leave should they fall pregnant while under employment. While pregnant women continue to fight for better rights while in the workforce it is hoped that the government and employers will continue to act to stop these inequalities. Seventeen year old Mitchell Bartlett, like many teenagers, is about to start a part time job at Woolworths. Mitchell is unsure about the full extent of his work conditions, he is however, happy with his wage of $15 an hour and that he has paid training. But he said that even if he didnââ¬â¢t like his conditions there was probably not much he could do about it. ââ¬Å"I probably wouldnââ¬â¢t have the confidence to confront my boss,â⬠he said. ââ¬Å"When youââ¬â¢re young youââ¬â¢re at the bottom of the food chain, so youââ¬â¢re much easier to exploit. It often happens. â⬠[5]. This is a common feeling among teens entering the workforce. With no real insight into how employees operate or their rights, teens can be exploited into working more hours, with less pay and no penalty rates. With important school requirements teenagers are often made to work more hours than is recommended for school aged employees. This can have adverse affects on students school work at a very critical time in a teenagerââ¬â¢s education. A survey by the Teachers Union found that students aged fifteen to eighteen are being forced to work more and more hours. The survey, of 300 students, found that 25% of students were on an Australian Workplace Agreement, while another 27% were on some form of employment contract but were unsure of exactly what it was. Although both government and employment groups claim that there are safe guards in place to protect student employees, teachers unions argue that not enough is being done to educate and protect young workers. The Teachers Federation has voted to improve the education of students on workplace information and they believe that the government and employers should follow their lead [6]. Discrimination towards older co-workers has become Australiaââ¬â¢s most critical employment issue in the workplace [7]. Division between co-workers because of age differences has always been a problem with interoffice relations. However in resent years, and with Australiaââ¬â¢s population ageing, discrimination towards senior employees has become more prevalent. The main issue of age discrimination in the workplace is the choice, by employers, to overlook older workers with the same, if not better, skills for younger employees. This inequality, although often not illegal, is an immoral decision to discriminate against older workers because of their age. In 2004, new legislation was introduced to help enforce remedies for age discrimination. The Age Discrimination Act (2004) covers aged workers in all areas of employment, job conditions, training, promotion and dismissal. The other issue of age discrimination is ridicule from fellow co-workers. Although any person can be subject to taunts from co-workers, the recent rise in complaints by age workers at the humiliation they have been subjected to by co-workers due to there age shows the extent that age discrimination has risen to. Fifty-seven year old Gerhardt had recently joined a company when two younger co-workers began harassing him. The two colleagues would place bets on Gerhardtââ¬â¢s age as well as ask each other loudly when they thought he would ââ¬Ëcark itââ¬â¢. 8] This form of bullying is not uncommon in many workplaces and increasingly more aged workers are being subjected to it. The Australian Human Rights Commission is set up to help those who feel discriminated against. The AHRC helps to enforce the legislation protecting senior employees. The unions, however, still believe that one in three unemployed 45 year olds canââ¬â¢t get a job because employers feel they are too old, a nd that 60% of unemployed 55 year olds are apparently considered to old to work [9]. More needs to be done to help out our increasingly ageing populations while in the workforce; this is a prime example of inequality in the workplace and is a critical issue that needs to be addressed by government, unions, employers and workers. The key groups dealing with employment relations are constantly looking for improvement in the area of discrimination in the workplace. The inequalities that many groups and individuals face on a daily basis are appalling. Every person deserves the right to earn a living in a safe and friendly environment. Although the debate as to how much can, and is, being done to stop these inequalities continues, it is certain that every person can help do their part in the workplace. Whether from and employer or fellow co-workers, if a person feels discriminated against in the workforce than that person should have an available means of support and justice. Government groups, such as the Australian Human Rights Movement and the Equal Opportunity for Women in the Workplace Agency, are helping those who have been discriminated against with education and action about employees rights in the workforce. New government legislation, like The Age Discrimination Act (2004), is increasing the lawful enforcement of discrimination against workers and helping to build equality in work environments. Through constant reevaluation and refinement, the government; along with employers and employees; can continue to make a difference in erasing workplace inequality and make employment a better place for everyone.

How to Improve Your English
How to Improve Your English Each learner has different objectivesà and, therefore, different approaches to learning English. But some tips and tools are likely to help most English learners. Lets begin with the three most important rules:à Rule 1: Be PatientLearning English is a Process The most important rule to remember is that learning Englishà is a process. It takes time, and it takes lots of patience! If you are patient, you will improve your English.à Rule 2: Make a Plan The most important thing to do is to create a plan and follow that plan. Start with your English learning goals, and then make a specific plan to succeed. Patience is key to improving your English, so go slowly and focus on your goals. Youll speak English well soon if you keep to the plan. Rule 3: Make Learning English a Habit Its absolutely necessary that learning English becomes a habit. In other words, you should work on your English every day. Its not necessary to study grammar every day. However, you should listen, watch, read or speak English every day - even if its for a short period of time. Its much better to learn 20 minutes a day than to study for two hours twice a week. Tips for Learning and Improving Your English Have patience: Remember that learning a language is a gradual process- it does not happen overnight.Define your learning objectives early: What do you want to learn and why?Make learning a habit:à Try to learn something every day. It is much better to study (or read, or listen to English news, etc.) 10 minutes each day than to study for 2 hours once a week.Choose your materials well:à You will need reading, grammar, writing, speaking and listening materials.Vary your learning routine:à It is best to do different things each day to help keep the various relationships between each area active. In other words, dont just study grammar.Find friends: Finding friends to study and speak with in invaluable and learning English together can be very encouraging.Keep it interesting: Choose listening and reading materials that relate to what you are interested in. Being interested in the subject will make learning more enjoyable - thus more effective.Relate grammar to practical usage: Gramm ar by itself does not help you USE the language. You should practice what you are learning by employing it actively. Use reading to help with other English skills:à Reading can be used to help with vocabulary, grammar, pronunciation and much more.à Flex your mouth muscles: Understanding something doesnt mean the muscles of your mouth can produce the sounds. Practice speaking what you are learning aloud. It may seem strange, but it is very effective. Exercises likeà tongue twisters can help improve your flexibility.Communicate: Grammar exercises are great, but having your friend on the other side of the world understand your email is fantastic!Use the Internet:à The Internet is the most exciting, unlimited English resource that anyone could imagine and it is right at your fingertips.

Pros and Cons of Term Limits for Congress
Pros and Cons of Term Limits for Congress The idea of imposingà term limitsà for Congress, or a mandatory restriction on how long members of the House and Senate can serve in office, has been debated by the public for centuries. There are pros and cons and strong opinions on both sides of the issue, perhaps a surprise, given the electorates less-than-flattering opinion of their representatives in modern history. Here are some questions and answers about term limits and the ongoing debate surrounding the idea, as well as a look at the pros and cons of term limits for Congress. Are There Term Limits for Congress Now? No. Members of the House of Representatives are elected for two years at a time and can serve an unlimited number of terms. Members of the Senate are elected for six years and also can serve an unlimited number of terms. Whats the Longest Anyone Has Served? The longest anyone ever served in the Senate was 51 years, 5 months and 26 days, a record held by the late Robert C. Byrd. The Democrat from West Virginia was in office from Jan. 3, 1959, through June 28, 2010. The longest anyone ever served in the House is 60 years, a record held by U.S. Rep. John Dingell Jr. The Democrat from Michigan was in office from 1955 to 2015. Are There Term Limits for the President? Presidents are restricted to only two four-year terms in the White House under the 22nd Amendment to the Constitution, which reads in part: No person shall be elected to the office of the President more than twice. Some conspiracy theorists claim that President Barack Obama was secretly plotting to repeal the 22nd Amendment and run for a third term in the white house. Have There Been Attempts to Impose Term Limits on Congress? There have been numerous attempts by some lawmakers to pass statutory term limits, but all of those proposals have been unsuccessful. Perhaps the most famous attempt at passing term limits came during the so-called Republican revolutionà when the GOP took control of Congress in the 1994 midterm elections. Term limits were a tenet of the Republican Contract with America. The contract called for a removal of career politicians through a first-ever vote on term limits as part of the Citizen Legislature Act. Term limits never came to fruition. What about the Congressional Reform Act? The Congressional Reform Act does not exist. It is a fiction passed off in email chains as a legitimate piece of legislation that would limit members of Congress to 12 years of service - either two six-year Senate terms or six two-year House terms. What Are the Arguments in Favor of Term Limits? Proponents of term limits argue that restricting the service of lawmakers prevents politicians from amassing too much power in Washington and becoming too alienated from their constituents. The thinking is that many lawmakers view the work as a career and not a temporary assignment, and therefore spend much of their time posturing, raising money for their re-election campaigns and running for office instead of focusing on the important issues of the day. Those who favor term limits say they would remove the intense focus on politics and place it back on policy. What Are the Arguments Against Term Limits? The most common argument against term limits goes something like this: We already have term limits. Theyre called elections. The primary case against term limits is that, indeed, our elected officials in the House and Senate must face their constituents every two years or every six years and get their approval. Imposing term limits, opponents argue, would remove the power from voters in favor of an arbitrary law. For example, a popular lawmaker seen by her constituents as being effective and influential would want to re-elect her to Congress - but could be barred from doing so by a term-limit law.

Action Research Proposal Thesis Example | Topics and Well Written Essays - 4000 words
Action Research Proposal - Thesis Example Content analysis will be used for analysing data that is going to be obtained from the study. There is a lot of information on Instructional Rounds about how to do them, prepare them and the reasoning behind them. However, there is little information that gets directly back to the teacher. It is because of this, I find it necessary to conduct research in order to establish how instructional rounds directly influence instruction in the class room. In this study, I will specifically focus on the teachers since some of them are stuck in their old ways, refusing to try new approaches while others are willing to give a try to anything new. However, most teachers fall between the two categories and this is the reason why this study seeks to investigate the measures that can be taken to implement instructional rounds in order to improve instructional competencies in teaching students from different backgrounds. The study will also investigate how instructional rounds in teaching can enhance the teaching profession in different contexts. The study will mainly focus on Union Groove Middle School which has a current enrolment of 876 with a composition of 416 males and 460 females. The ethnicity composition of the students is as follows: White (325), Pacific Islander (10), Black (224), Asian (45), Indian (6) and Hispanic (200). The number of students with 504 plans stands at 82, and the number of at risk students is 224. The total number of students in special education is 85. The composition of the total population of the students is ideal for conducting a study about the effectiveness since it is comprised of six ethnic groups as mentioned above. Usually, teaching students from diverse ethnic backgrounds can be challenging since these people have different levels of understanding by virtue of their experiences. Elements such as language and cultural differences also contribute to the level of understanding of the students in as far as

How Eukaryote Cells Came into Life Essay Example | Topics and Well Written Essays - 1500 words
How Eukaryote Cells Came into Life - Essay Example Prokaryotes had been first found around 3.5 billion years, which is just a billion years following the formation of the earthââ¬â¢s crust. Till today these life forms remain to be the most profuse ones, and since they have a very varied metabolism as compared to the eukaryotes, we can find a great many kinds of prokaryotic types. Since eukaryotic cells comprise of a huge majority of multi-cellular organisms and other complex cells, their origin has been considered a great highlight in the evolution of life. It is not really possible to determine when exactly these cells came into existence but according to Knoll (2006) it was around 1.6 ââ¬â 2.1 billion years ago that eukaryotic cells took form. Certain acritarchs have been said to have originated 1650 million years ago and Grypania is an alga that was probably discovered to be approximately 2100 million years back. Besides this, it is the opinion of biomarkers that stem eukaryotes had come into being even before this and, as an example, steranes were found to be present in Australian shales almost 2.7 billion years ago. In 1966 the endosymbiosis theory was proposed by Lynn Margulis and he said that the prokaryotic cells and the initial eukaryotic cells lived together. At the beginning there was much hesitation in the acceptance of this theory. Eukaryote cells are more complicated and are set inside membranes while prokaryote cells do not have any membrane bound organelle. Another difference between these two cells is that eukaryotes have a cell nucleus while prokaryotes do not. This nucleus contains the DNA of the cell. Secondly, the size of eukaryotes is bigger as in the width and thus the volume is also more as compared to the prokaryotes. Chromosomes are present in eukaryotes which are actually where the DNA is. The movement of eukaryotes are controlled by motile cilia, also called flagella; and the flagella of eukaryotes are quite simple as compared to those in prokaryotes. Besides this, eukaryotes are like prokaryotes in respect to the plasma membrane and its function, but there is slight difference in the setup. Symbiosis as a mutually beneficial relationship happens when there are two species living together or closely for very long durations. This association is actually known as symbiotic, the word meaning to live together. Now there are different kinds of such a relationship and one is mutualism in which both the species get something out of the relationship. A very common example is that between plants and fungi. MAIN BODY Eukaryotes have been explained through various ways. An attempt has been made to explain the origin of these cells through the endosymbiotic theory as well, which was first proposed in 1905. This theory is basically concerned with the mitochondria, plastids and similar other organelles of the eukaryotes. This theory proposes that there were some specific kinds of organelles which actually came into being as free living bacteria. These were then taken within another cell as endosymbionts. Thus took place the development of cells and proteobacteria resulted in mitochondria while cyanobacteria lead to chloroplasts. In 1966 this theory was again proposed by Lynn Margulis and he said that the prokaryotic cells and the initial eukaryotic cells lived together. At the beginning there was much hesitation in the acceptance of this theory. Eukaryotes have double membranes around them. Within these membrane-bound compartments take place certain metabolic activities. As
