Community of Cars

In â€Å"Community of Cars† by Ryan Brown, the author uses sarcasm to Inform us that we are a lazy, self-destroying community. He relays every negative thing about our environment and health to our Increased dependence on cars. Brown seems to cry out to the world that we need to change our ways before It's too late. He wants people to be more mindful, and to not Just throw out the environment. Brown begins his argument with a stroll down the authors' childhood.He refers to the numerous afternoons spent strolling with his grandmother to the local grocery store. Many people can refer to this as an emotional appeal. Brown than appeals to our values by saying the â€Å"friendly conversations we used to have when passing an acquaintance while walking have been replaced with honks of a car horn† (Brown 1). He points out that Americans are in a mind state of driving over walking. He also says that if we drove less, our environment, communities, and personal health would all sh ow positive effects. â€Å"That automobiles are environmentally harmful is unarguable† (Brown 1).Brown uses the argument of automobile emissions polluting the air and then resulting in acid rain. He says with the combination of cheap gas prices and high gas mileage cars, there is no wonder the drivers society has continued to thrive. He points out that just because people drive fuel efficient cars, it does not mean there doing anything positive to the community. Because of their fuel efficient vehicles they drive more because it's cheaper. Using a fuel-efficient car to drive miles to the superstore instead of walking to the corner store is not helping.Brown points out the ultimately it is our choice whether our communities are great places to raise our children, or if they are just mere pit stops on the highway. He poses that Americans have disregarded the isolating effect of convenience, and thus we are blindly setting ourselves up to destruction. Such is a consequence that many have not thought of, and Brown makes a convincing appeal. â€Å"New Urbanism and other social reform movements promise to bring back the days of centralized, walk able communities, Incorporating features such as wide sidewalks and narrow streets† (Brown 3).Brown believes that with a better community comes a better strength of life. Brown states that roadways tear up countryside destroy wildlife habitats and routes. Browns Interpretation of the rise In gas prices Is the government telling us to watch our spending. The government has gas prices low enough to keep the consumers happy, but high enough to pay for our environmental struggles. The decline of public health due to lack of exercise Is another argument Brown uses to his advantage.Brown uses an example from Amanda Speak In saying â€Å"Living In the suburbs Is linked to dating more higher-calorie fast food† (Brown 2). Obesity In children has more than doubled In the last three decades. This Is not surprising because 1 of every 3 meals that a child eats is from a fast food restaurant. Brown states that us Americans think Witt our wallets. According to nil, ten only times Americans take a stand on an issue is if it's convenient and affordable. It seems like the cause and effect of everyday life prompted Brown to write this argument. He claims that as our driving rates go up our health goes down.He claims we are lazy and then states almost anything we need on a daily basis we can get through a Drive-Thru window. Now we no longer have to exert ALL the energy it takes to walk across the parking lot and to shop around. You can now do almost every daily chore without leaving the comforts of your front seat. Paul Higgins from University of California believes that walking would no doubt fix two of Earths biggest problems; global warming and obesity. Brown believes that the new tight relationship between a man and his â€Å"Beauty' is a reversible trend.He believes that the return to days gone by is an achievable and desirable goal. All in all, Brown uses a variety of strategies to argue his thesis that too much reliance on automobiles is costing America its health and heritage. The vast amount of consequences of when we drive instead of when we walk has had far- reaching effects that many people may not have considered. Brown assembles a triple threat by appealing to our logic, emotion and values. To Brown, cars are an incredible thing, but not worth losing the environment, our communities, our personal health, and lives.

Overview The work to continually improve Heal th and Safety has grown in stature throughout the Company since the last reporting year.Generally awareness of Health & Safety has been raised further by the Employment of a Productive Health and Safety Advisor working along side the Health and Safety Manager to ensure compliance is met through Auditing, Documentation Evaluation, Investigation works, continual training, safety meetings and various safety bulletins, as well as filtering all Supervisors and Managers (In due course) through either the SSSTS (Site Supervisors Safety Training Scheme) or the SMSTS (Site Managers Safety Training Scheme) which has enhanced the Health and Safety Culture throughout the Company.The Health & Safety Manager and Team has continued the good work within the company to ensure that Site Managers meet their responsibilities, although in some areas this has met with some resistance with some managers still failing to complete weekly document returns. Most Managers have achieved carrying out risk assess ments & reviews on existing risk assessments as well as producing Method Statements which in the past was lacking. 2. Key Achievements 2008/2009 2. 1 Policy Development and ImplementationA key objective of the Health & Safety department for this year was to continue the development and implementation of health and safety policies across the company, integrating as far as possible already established systems to ensure minimal changes to working practices. The following guidance has been ratified and implemented: ? No Lone Working – Continued from Last Report. ? Young Persons Health & Safety Risk Assessment – Continued from Last Report. ? Implementation of the Health and Safety Action Plan – Within the new Health and Safety Manual. Implementation of a Worksafe Policy – Within the new Health and Safety Manual. ?

Health and Safety Annual Report 2008/2009 Report No: 2 J Coffey Construction LtdIt should also be noted that, while important, the measurement of the accident rate is a measure of failures, not successes. However although there has been a slight rise in the reporting of accidents the Accident Incident Rate and the Accident Frequency Rate has decreased over the reporting period in relation to the number of employees to the previous year. The Health and Safety Department agrees to use the new Method Statement Proforma and all introduced check sheets to achieve uniformity throughout the company as a performance measure tool together with the new Health and Safety Table. 4.Raising the Profile of Health and Safety The Health & Safety Manager issues monthly health and safety bulletin sheet from The Worksafe Partnership Ltd and his own, providing news of new policies and other health and safety matters of interest as well as e-mailing information from the HSE Website on relevant subjects. Health & Safety HSE â€Å"Myth of the Month† are c ontinuing to be published on the Health and Safety Notice boards. The Site Managers have, and continue to be active in the way of conducting Toolbox Talks in compliance with current HSE Campaigns and relevant implementations and changes throughout the company.The Health and Safety Manager has introduced a Monthly Health and Safety Table, marking each site on their Health and Safety Performance on a variety of subjects, where the winners each month receive a Plague. The Company has now become a member of ROSPA (The Royal Society of the Prevention of Accidents). 5. Co-operation and Co-ordination Co-operation and co-ordination with other agencies has continued successfully. A good liaison link has been established with the Health & Safety Executive, British Safety Council, IIRSM (International Institute of Risk and Safety Management) and ROSPA. 6.

Dangerous sports Essay

According to personal expediencies many hobbies and interests are come and gone, but always dangerous sports and its news always had a large presence.Formula one and Heli Skiing are two of world famous and very dangerous sports, both sports have the impact and the interest around the world. Formula 1 is originated by Britain over 60 years ago and Britain already won many world titles from this sport therefore people have a high interest in this game even though this sport is very dangerous. Fatal accidences are common in Formula 1 racing, in 2002 world championship grand prix â€Å"Aytona Senna† the world famous Brazilian Formula 1 driver crashed in front of massive crowed during the race and dead on the spot. This accident’s impact in many countries to reconsider about this sport and its standers. Even after this accidence there were much fatal accidence happen in Formula 1 racing but still this sport is very famous among whole world. Heli Skiing is also famous and ver y dangerous sport, according to this sport’s history even very experience skiing players also can get serious damage or even fatal accidences during this sport. Recently world famous Michael Schumacher had ski accident and still fighting for his life and Schumacher knew that this sport is dangers but according to many articles shows that its danger makes Michael Schumacher’s interest to this sport. According to above two sports shows that dangerous sports have a major drawbacks and also in some cases it cost human life’s but my personal view argue that if all the dangerous sports can be done with high standards. For instance Formula 1 not causing much accidence after 2006 as compare to 1960 to 2002. Therefore dangerous sports also shows that with setting safety measures and appropriate high standards even very dangerous sports can be done without causing any incidence. The risks can be lessen and these sports are highly populated by more than a decade therefore cannot agree with the statement. Humans are always like to get high risks and most of high risking sports will get famous within no time therefore rather than discouraging those sports can help to lessen accidence and can increase the level of standards.

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

Neural Networks - Research Paper Example This paper presents an overview of the Artificial Neural Networks (ANNs). This paper will outline the basic idea, some history and uses of ANN. Basically an artificial neural network is a collection of programs of data structures that is almost capable of the process of the human brain. In this scenario, a neural network encompasses a wide variety of processors that work collaboratively, each with its own small sphere of facts and makes use of the data in its local memory. In addition, an ANN can be considered as a computer program or simulation that is built through a wide variety of clear-cut and extremely unified processing components that are capable of managing information by means of their active state reaction to inputs. In fact, artificial neural networks have the capability to solve those problems that are difficult to resolve using traditional processes and techniques, as well as sometime a lot of them have been tackled through neural networks, for instance forecasting gras sland community, analysis of seismic signals or solar radiation, control of chaotic dynamical systems, data and air quality control and categorization of remotely sensed information (Benvenuto & Marani, 2000; Giles, 1998; Laudon & Laudon, 1999). According to (Stergiou & Siganos, 2010), an artificial neural network is a data processing model that is inspired by the method of biological nervous systems information processing. Neural Network is also a renowned and heavily researched area of the AI. Stergiou & Siganos (2010) described that in the neural network field the working of human neuron is copied into the computer based systems. In addition, the neural network is an AI based computer program which imitates the human nervous systems’ working. It is based on neural net which has weights on each node that can be adjusted to make suitable decisions. Such systems are typically seen in automatic driving systems that are under-research and at the early stages of development (Ste rgiou & Siganos, 2010; Laudon & Laudon, 1999). The history of the artificial neural networks can be traced back to the 1940's with the introduction of the first neural network computing model, which was presented by McCulloch and Pitts. In the 1950's, Rosenblatt's work got a considerable attention of researchers. Additionally, this work was further resulted in a two-layer network, the perceptron, which was able to learn various classifications by making changes to connection weights. Without a doubt, the

The Role, Purpose and Value of Design and Technology in the School Essay

The Role, Purpose and Value of Design and Technology in the School Curriculum - Essay Example Education should be made equally accessible to everyone despite of the race, ethnic or social class to which a person belongs; this would not only create a more equitable society but also create a harmony among the people living in the society. One of the fundamental reasons for the striking income disparity between people of the same society in this capitalist world lies in unequal access to education for everyone which eventually puts people belonging to lower income classes at disadvantaged and hence they never get out of their poverty trap (Matheson, 2008). Furthermore, the purpose of education is to make children aware of what they want to do with their lives, what opportunities lay ahead, what are the possible fields they can progress into etc. Above everything else, education helps the individuals to secure their future not only for themselves but for their families as well, as education is positively related to higher incomes. Studies have consistently proven over time that i ndividuals with a higher college or university degree end up earning more as compared to their counterparts with less education (Owen-Jackson, 2007). Moreover, another crucial facet of education is the chance of upward social mobility it provides to individuals who seek higher education. In this fast paced world where competition has become severe and only survival of the fittest is possible, education should not be restricted to bookish and theoretical text only but it must also incorporate informal education and knowledge of skills that would entail an individual to live a better and prosperous life (Posner, 2003). Importance of education has become more pivotal than ever before as the world has transformed into a global village where information technology now plays an unprecedented role in our lives; economies which once used to be agricultural centers have changed to service and manufacturing economies where education and skills are imperative for the survival (Posner, 2003). A part from the monetary and financial gains of education, another purpose central to education is to create a civilized society where everyone is given equal rights and where ethics and morals are given due importance for a higher standard of living so that everyone can live peacefully in a secured environment. Education inculcates an ability to differentiate what is right or wrong in life. It helps individuals to distinguish between the acceptable and unacceptable values. It makes people politically and socially aware of their responsibilities as a citizen of the state. In other words, education can be attributed as a fundamental on which a society with higher economic, political and social growth is formed; as a major role of education is to integrate people in order to keep social setup stable and smooth (Sleeter, 2005). Lastly, in a nut shell education is an investment for lifetime which provides more freedom to live a better life and the benefits of which are not only restricted to individuals but it contributes to the society in which the person resides. It is the role of government to make sure that every individual is getting an equal and an unbiased opportunity to access education in order to form an equitable and just society. Importance of Curriculum with a focus on UK Education System: Education is crucial for the development of a civilized socie

Research Methods - Essay Example The main purpose of these industries is to develop products that could be used in everyday life and produce more and more employment opportunities. The research involves finding potential problems in the present products used and resolving them by upgrading them or using new products. The researchers found the flexibility of a product enables it to be used by more clients. Another important factor probably the most important one is the cost. If the final product is expensive there will be only few takers for it. Therefore research has been done to use cost effective applications. Another important feature developed by the researchers was reverse engineering. In reverse engineering the work is done from final stage to the initial stage. The main purpose of reverse engineering is to extract the code from the final product, working on the final product to the scratch. By using reverse engineering technique one can extract their competitors application and introduce own application in the market accordingly. Qualitative research methods are more often used as it involves observation of data that helps in finding solutions to the problems. Qualitative research has been categorised into three categories named as positivist, interpretive and critical. Positivist research methods

Dell Computer Make to Order (MTO), Make to Stock (MTS) & Assemble to Assignment

Dell Computer Make to Order (MTO), Make to Stock (MTS) & Assemble to Order (ATO) - Assignment Example The researcher states that the Make to Order process maintains quality and the products can be personalized during manufacturing and delivery that creates value for customers. This process has no finished goods inventory. The make to order has a disadvantage since it has intermittent production. Dell Company can benefit from MTO process due to reduced inventory space and can customize their products. From a tax, related standpoint Dell Company may benefit from the process. In terms of customization, Dell Company can customize their products with materials, size, and color.The Company may benefit economically from the process since assembled goods must have more warehouse space. Delaying assembly until a customer makes an order reduces labor cost for the company before payment. However, the company may experience delays since products take longer to produce and deliver. Customers may opt to make orders from other companies that offer quicker deliver products. Assemble to Order is a pr ocess that involves making a part and sub-assembling the products. The process is completed when a customer makes an order. It is a business strategy in production that produces quickly and customized in certain ways. It requires that basic parts are manufactured but not assembled. When an order is placed, the parts are assembled and sent to the recipient. The process has its own advantages in the sense that it has fewer inventories and the service is faster. Its main disadvantage for Dell Company is that it has WIP inventory. This process is appropriate for a computer industry Dell company can benefit from this when large numbers of sub-assemblies are put together. For example, assembling the motherboard, video cards, fans, and battery power are put in one location and the final assembly of the laptop is made easier when an order is made.

Facebook as a gateway to marketing activities - Essay Example Facebook is one of the most renowned social network sites in the internet that tries to connect people around the world. It is one of the leading social network sites that have captured billions of people to get connected through virtual friend request and invitation. This website is known to provide more than just entertainment because it is also used to disseminate information to each of the member of the site. In today’s world’s activities where information can become so confusing at some point or very helpful in a way, people may no longer have the time to determine how they are bombarded with diverse idea everyday. In the case of website Facebook people are constantly moving with the trend without them trying to notice how they are used in it. In this paper, the proponent tries to emphasize a specific issue in which people can hardly notice about its existence. This is in line with the marketing strategy used by marketers by tapping social network sites particularl y Facebook. Facebook as a gateway to marketing activities Facebook members seem to know little about it that when they agree with the terms and conditions of the social network site during registration of their account, technically all information they shared with the site belong to Facebook management. The information they shared become the real property of Facebook management in which the member may actually have no real control over them. This is an advantage at the side of Facebook management because they may have necessary data to be processed into useful information for whatever purpose it may provide for their further benefits. Marketers are always studying their consumers and these include demographics or characteristics of human population including sex, religious background, social orientation, culture, education and many more. All of these information are very important to be learned in every marketing activity because through them a marketer will be able to create strate gic move in order to stimulate needs for their product or service offerings. Fortunately, marketers find their way in social network sites to study human behavior and characteristics of human population. For instance, the existence of News Feed and Mini Feed features at Facebook actually triggered privacy issues and discussion of their future influences (Hoadley et al. 50). Certainly this is just a proof that online social network site is not just built for purely interaction among members, but its design is leading forward to spiraling growth of tremendous possibilities. As one result that can be clearly observed, Facebook has become an easy way for business-oriented individuals to promote their service and product offerings. If this is the thought going on with the mind of these simple and ordinary individuals, then certainly there can be more going on in the minds of marketing professionals. In fact, the on-going trend of marketing activity is reaching to interactivity (Deighton and Kornfeld 4). This is a real case going on at Facebook as a social networking site adhering to create healthy interaction among people in every walk of life around the world. Facebook is built to create profit Facebook as an online social network site is instituted to gain and create profit. In order to reach this corporate goal, the management needs to acquire many members as many as possible. This is the reason why there is always an option for ‘friend request’ so as to substantially increase the number of members. The higher number of members is directly associated with the profit or revenue to be obtained. In 2010, the Wall Street Journal reported $710 million estimated revenue of Facebook but other estimates had been revealed to be around $1 to $1.1 billion. These are just estimates at some level but the main point is that Facebook does not start gaining these ranges of revenue. They had started from a very humble beginning. Everything started to go for Facebook ’s favor when the number of their online members had

Network Security - Essay Example In order to prevent such attacks in the future the following measures should be thoroughly applied. The employs should be enforced with strict regulation when it comes to dealing with spam mail. The employees should be educated on how to avoid suspicious emails (Minimizing the impact of the RSA SecurID breach, 2011). Security monitoring technologies should be used to monitor changes in user privileges and also add manual approvals to critical infrastructure and software (Minimizing the impact of the RSA SecurID breach, 2011). Also the infrastructure hosting critical software should be hardened and they should be monitored closely for remote and physical access. Help desks activities and any other activities that may result in information leakage should also be examined (Minimizing the impact of the RSA SecurID breach, 2011). Since the attack has taken place recently the full damage is too early to be predicted. According to RSA’s FAQ for the customers the threat of direct attack to the customers have been denied since the information stolen is useless, without the information held by individual customers (Inc.). Because of that RSA is confident there no immediate reason to call back any products. The local user should apply them selves with strict rules handling any type of spam mail or downloading attachments from unknown sources. Also they should avoid sharing their important credentials (usernames, passwords) with strangers. Even though the company effort and training to avoid spam based attack has not paid off. It is a good lesson to everyone (Litan, 2011). By utilizing the thousands of computers in DC++ file sharing service network this DoS have been launched against 40 companies over the last three months (Reimer, 2007). If such attack is launched using a single computer the attacker is easy traceable. So overcoming this barrier, using DC++ network’s

Evaluate the application of revenue management practice in the hotel Essay

Evaluate the application of revenue management practice in the hotel industry and discuss its impact on customers in the hotel industry; - Essay Example dification in the general handling of revenue management, inventory allocation, pricing strategy, use of information and channel management as concerns to revenue management tend to redefine the field. Similarly to how detailed past analysis might have a representation of the best pricing practice during the 1990s, apparently, the stock market-impacted algorithms exist in the cutting edge of modern pricing thought. Comparably, the highlighting on occupancy or average day to day rate, which might have dominion over revenue managers’ outlook over two decades ago has led to the dominance of revenue per available room i.e. RevPAR. Instances like this abound hence this article will endeavor to share all of the revenue management expertise with readers, in a series examining the modern revenue management’s best practices (Kimberley, Trevor & Juston 2008, p.12). Pricing tends to a feature of revenue management, which features a number of intriguing, as well as innovative developments recently. Whereas pricing has continues to be a significant driver having an effect on both occupancy, along with RevPAR, in the present environment surrounded by exceptional price transparency, rates have taken an even bigger role. Ascertaining the optimal rate to give to a potential customer tends to be one of the most significant concepts of revenue management. The basic fact that the appropriate rate- one that achieves the balance between replicating enough demand in maximizing occupancy, while at the same time, not deserting money on the table within the form of low down ADR turns out to be the key to a profitable revenue management strategy causing pricing perhaps the most significant concept of revenue management. Then how is a hotel capable of determining what the best rate has to be any time? In the past, this would center on historical analysis, while , at the same time, computed by the application of a discount to a fixed rack rate. In this case, there is no achievement of

Comparing and Contrasting Two Versions of Macbeth Essay Example for Free

Comparing and Contrasting Two Versions of Macbeth Essay The two versions of Macbeth were made in different years. The BBC version was lower budget and set almost as if it is a play being performed on stage. The Polanski version was a big- budget film which is set in real, outdoor locations. However, though each film is very different, they are both adapted from Shakespeares play. Sound is very important in a film; sound consists of three elements, these being dialogue, music and effects. In the BBC version of Macbeth, dialogue is the most important of these sound elements; this is because the BBC version is very closely related to Shakespeares play. In the BBC version, sound is used to tell everything; there are very few sound effects and very little music. Conversely, in the Polanski version all three elements share important roles. While the BBC version follows Shakespeares original script very closely, Polanski makes a number of changes to the script and sequence of events. An example of the original play being adapted is in scene one, in which he chooses to make very long so that he was able to miss our parts later on in the story. Instead of the witches meeting in the first scene, the witches meet and cast a spell using an arm. In the BBC version, this particular reference to a body part does not come until scene three. This is why scene one in the Polanski version is so long. The dialogue in the BBC version is identical to the dialogue that Shakespeare wrote. Though dialogue in the BBC version is the most important feature, there is music. Music is used to build up suspense at the very beginning of the film, this music starts and stops as does the use of thunder as pathetic fallacy. This creates an eerie and unpredictable effect. In the Polanski version, sound is a more subtle element. In scene one, everything is action with quiet sounds and the witches do not speak until two minutes into the scene. On the other hand, the witched begin to speak almost immediately in the BBC version. The mise en scene in both movies is important. A movie can be more realistic than in a staged play. This can be seen clearly in the Polanski version which uses elaborate, individual costumes which look very true to life. This is helped because the Polanski film had a big budget. The setting in the Polanski film was a real landscape and on location. Many props are also used; for example in scene one when the witches push a pram which contains an arm, a dagger and blood. Props add to any movie or play to make it more interesting. In this particular case, however, the props symbolic of what is to happen later in the play- gory murder. In the BBC the mise en scene is much simpler, being set more like a stage version- more dialogue, less scenery. In scene one there is only one setting. This scenery is much simpler and clearly filmed in a studio, it shows the witches situated on a rock in a dark area. The costumes the witches are wearing plain undistinguishing clothe: their black shawls are almost identical making the audience concentrate more on the dialogue, the mise en scene is a bonus, as opposed to in the Polanski version, where the mise en scene plays a more important role. Visuals are very important in both versions of Macbeth. In the BBC version there is only one shot in scene one, which makes it very similar to how it would be performed on stage. However, the difference is that the camera zooms in a the beginning and zooms further in to a close up of the witches hands at the end. This same effect could not be achieved in a stage version, In the third scene of the BBC version, there are many shots. This is because the scene is longer and includes more characters: Macbeth, Banquo, the three witches and two messengers. Whereas in scene one there were only three witches. In the Polanski version there are many shots; fifteen in scene one. Each shot is carefully made to portray something. Unlike in a play, a movie effectively tells the viewer exactly what to see at a certain point. One example of an important shot is the third shot in scene one where the shot goes from the three witches digging in the sand to a seagull flying in the sky. This shot may seem random at first but it was specifically chosen to show time passing. It can also symbolise a coming storm- seagulls flying inland means that there is bad weather brewing at sea. This can be connected as a sign of what is going to happen later in the story and what the witches are preparing, a bad spell. The use of lightning and colour is important in both versions. This can be noticed when the lightning in scene one in the BBC version and Polanski version is both red at the beginning. The colour red symbolises blood, a major element in the play and gives an indication to the audience of the bloodshed and murders to come. Colour is also important to portray the time of day. This is shown in the Polanski version at the beginning when it is dawn and the sky turns from red to blue, becoming brighter to show the sun rising. A red sky can also symbolise bad weather, as does the seagull later on. The saying goes: Red sky at night, shepherds delight, red sky in the morning, shepherds warning. I think both versions are excellent stories of Macbeth. The BBC version is more like the original play and focuses on the literary content; the Polanski version contains more action. Both films are helpful in aiding students to understand the content and themes of the play because the BBC version is very similar to the original play- the speech is the same, however, the Polanski version is more cinematic which makes it more exciting and helps students to enjoy the play. I preferred the Polanski version because it is not completely directed on dialogue but also on action and scenery. I found this more interesting and more realistic than in the BBC version.

Africa Change over Time Essay Example for Free

Africa Change over Time Essay Around the period during the second World War and the Cold War, a Red Scare went on in the most powerful and influential capitalist countries of the world. The Red Scare was basically a fear of the spread of communism. According to the Domino Theory, which was developed in that era, if a specific country turned to communism, communism would soon spread to all the other countries in that area. This fear caused the United States to jump into action at the slightest sign of communist influence in many places in the world, especially subsaharan Africa. However, over the years, this fear has eased, and the U. S. is more prone to attempting to aid these nations, rather than destroying them. In sub-saharan Africa, from around 1900 to present day, conditions there have both changed and stayed the same. On one hand, western involvement in the area has changed, but on the other hand, the constant civil wars and oppressive circumstances from the past still exist today. Sub-saharan Africa from the beginning of the 20th century up to this present day has been under constant civil war. South Africa, Sudan, Mozambique, Angola, Ethiopia and Zaire (or the Republic of Congo) are good examples of this. South Africa was first colonized by the Dutch who integrated themselves into the country. However, in the late 19th century, the English conquered South Africa and moved the Boers (the Dutch-Africans) to the north of the country where they clashed with the native Zulu tribe. When diamonds where later discovered in that area, the Dutch and the English had wars for the territory. In Sudan, a fundamentalist Islamic group that sits at the head of the government was at civil war with a rebel Christian group. The main reason for this conflict was the obvious religious differences. This conflict has ruined many crops and homes of civilians and forced many others to flee the country. In Mozambique the civil So? a Gruber war there was a proxy war between the Soviet Union, that influenced a Marxist government in that area, and the U. S. , that sponsored a rebel movement to usurp the communist government. Similarly, in Angola and Ethiopia, a proxy war, sponsored by the two Cold War superpowers tear the countries apart, causing widespread famine and suffering. Finally, the civil war in Congo, that has lasted for decades, was a tug for power between both left and right leaders who, nonetheless, where all power hungry and corrupt. In sub-saharan Africa, there is a continuous pattern of oppression of the people. The examples for this seem to be endless, between constant genocides and militaristic dictators, the people in sub-saharan Africa suffer and die in squalor. In Rwanda, a mass genocide erupted when the Hutu tribe blamed the Tutsi tribe for their leader’s death. In a time span of 100 days, nearly 8000 people died, and countless more were injured in unspeakable ways. Throughout all of Africa, the use of child soldiers has become extremely popular. It is not uncommon for a 10 year old boy (sometimes even younger) to be drugged and paraded down the street while they shot innocent civilians and mutilated them. The living conditions in many nations are unspeakable. Many families live in shacks with no running water, and very few of them have any means of contact to the outside world (television, phones, radio, ect. ). Constant civil war force many families to flee their country, creating refugees for other countries, who stick them all in refugee camps. Most methods of war involve hurting civilians, in Sudan, a popular resistance method was scorched-earth policies. Here, armies would burn down everything that would be essential to life, ensuring that no aid would be available to their opponent. In South Africa, mostly, apartheid was practiced to the extreme. Not only were there segregated bathrooms and schools, but entire towns. A white minority would live in splendor, while the black, native majority would live in squalor. From 1900 to present day, the world’s involvement in sub-saharan Africa has drastically changed. Western involvement in sub-saharan Africa mainly consisted in imperialistic motives and proxy wars. However, its started to change into wanting to help improve the standard of living. South Africa is a very good example of this. In the times of imperialism, England and Holland both had interest in South Africa. England wanted to create colonies there and the Dutch were already there. After the Dutch kicked the English out of the country, they set up their own personal empire in the region. They created a world where whites ruled over blacks. The insalubrious living conditions there for the native black majority eventually set off the rest of the world. After years of both internal and external pressure, the South African government finally ended apartheid in the country. This type of change goes on in many African countries. Most of these countries suffer due to futile proxy wars set up in the region by both Soviet and American forces. After decades of watching this fighting, the world decided to step in and help. Red Cross is sent in there to aid and occasionally, the United Nations tries to stop these wars. Non-profit organizations, such as UNICEF and Hand Up Africa encourage western civilians to take part in working for peace in the sub-saharan African nations. Despite the change in western attitude towards sub-saharan African nations, most of them still are under the threat of constant civil war and their people live in oppressive circumstances. Many of these civil wars were caused by the American fear towards communism and tribal and religious differences. These conflicts bring rise to militaristic dictatorships and decrease the standard of living prominently. However, in retrospect, western nations seemed to have repented for their destruction of the large continent and continuously attempt to rebuild it.

Additive Manufacturing; Stereolithography in Dentistry

Additive Manufacturing; Stereolithography in Dentistry Introduction: Digital revolution because of computers has made the previously manual tasks much easier, faster and more reliable at a reduced cost. Such modifications are always welcomed in dentistry, especially from materials and manufacturing perspective. The digital revolution in the form of dental CAD–CAM took place many years ago, since than many modified systems have appeared on the market with great rapidity. It is expected that another digital dental revolution will take over dentistry in the form of layered fabrication techniques, once they are able to produce high quality dental prostheses. This situation has also posed great challenge for the material scientists in the form of materials that are suitable for long term use in dentistry and oral environment. This can potentially take dental materials research in a totally different direction. Additive manufacturing: Dentistry is the most suited field for additive manufacturing, as it is associated with rapid production of customized units made to fit the patient with high degree of precision and accuracy. In principle it creates a series of cross-sectional slices from a 3D computer file which are then printed one on top of the other to create the 3D object without any material being wasted. Additive manufacturing technologies includes many and Stereolithography (SLA) is one of them. Stereolithography (SLA) Stereolithography (SLA) is the most widely used rapid prototyping technology. The term â€Å"Stereolithography† was first introduced in 1986 by Charles W. Hull, who defined it as a method for making solid objects by successively printing thin layers of an ultraviolet curable material, one on top of the other. Materials and Required time: A number of materials that the industry uses have increased greatly and modern machines can utilize a broad array of photo curable polymers. Timing depends on the size and number of objects being created, the laser might take a minute or two for each layer (a typical run 6 to 12 h). One can now even print 50 to 80 dental crown units in 56 minutes with high quality mode. Applications in dentistry: Dental applications are very suitable for processing by means of SLA due to their complex geometries, low volume and strong individualization. Most common are models fabricated from intraoral or impression scans. However, popularity is gaining for orthodontics and removable prosthodontics. 1. Production of anatomical models: SLA models are preferred because of higher strength, higher temperature resistance, lower moisture absorption, and lower shrinkage. They can be sterilized for surgical use, and literature has shown superior accuracy (Barker et al., 1994, Choi et al., 2002, Cunningham et al., 2005). Table-1 summarizes basic characteristics of the three most common types of 3-D models used in the United States. SLA clinical models are used as an aid to diagnosis, preoperative planning and implant design and manufacturing. Surgeons use models to help plan surgeries but prosthetists and technologists also use models as an aid to the design and manufacturing of custom-fitting implants. These models are particularly very useful for restorative rehabilitation of oral cancer patients. Medical models are frequently used to help in the construction of Cranioplasty plates. The models are effective tools to facilitate patient education and as a teaching aid for students and ju nior colleagues. 2. Manufacture of crowns and bridges, resin models: Its use is gradually being extended to include the manufacture of temporary crowns and bridges and resin working models for loss wax casting. 3. Production of removable partial denture frameworks: The removable partial denture frameworks is made using rapid prototyping, SLA technique. It was developed by 3D Systems of Valencia, CA, USA in 1986. 4. Production of individually-customized digital aligner models for orthodontic use: Whole trays of individually-customized aligner models which serve as extremely accurate base-mold tools upon which the clear aligners are then thermoformed, can be produced by this additive technique. 5. Manufacturing of scaffolds for bioengineering and nerve guide conduits: Scaffolds for bioengineering and nerve guide conduits for peripheral nerve regeneration are the newer applications of a similar process i.e. microstereolithography ( µ SLA). Future advancements: With the improvements in the speed, reliability, and accuracy of the hardware, additive manufacturing will seriously compete with traditional manufacturing in creating end-use products. Many possible biomedical engineering applications might be available in the coming years. Conclusion: It will still be many years before the machines will be able to produce work of a quality that can be achieved by the best dental technologists in the world. For the dental materials scientist these technologies will throw up a whole new way of materials processing and with it the opportunity to use a whole new range of materials.

Pie in the Sky :: Essays Papers

Pie in the Sky Among the oddballs and exhibitionists who clustered around Andy Warhol in the 1960's and 70's perhaps the scariest was Brigid Berlin, a chubby, motormouthed rebel from an upper-crust New York City family who relished the way her "underground" celebrity embarrassed her proper conservative parents. Her father, Richard Berlin, a friend of Richard M. Nixon and an admirer of Senator Joseph R. McCarthy, ran the Hearst Corporation, which he had helped save from bankruptcy in the 40's. Her mother, Honey, was an elegant, ladies-who-lunch-style socialite of the old school. Ms. Berlin was one of Warhol's favorite telephone companions, and she taped hundreds of hours of their conversations, some of which were adapted into a play called "Pork" that flaunted the Berlin family strife. Like many of Warhol's acolytes, she fancied herself an artist and was one of the first art world personages to work with a portable tape recorder and Polaroid snapshots (she specialized in double exposures). Her more notorious antics included a theatrical performance in which she telephoned her parents from the stage without their knowledge and broadcast live her mother's furious tirade about her lifestyle and choice of friends. That lifestyle included an addiction to speed (in the 1966 Warhol movie, "The Chelsea Girls," she played a pill-pushing lesbian who shoots up in front of the camera) as well as an eating disorder that pushed her weight to 260 pounds. Despite her obesity, Ms. Berlin often appeared nude in Warhol's movies, displaying not a trace of self-consciousness. Excerpts from her taped conversations with Warhol and with her mother run through "Pie in the Sky: The Brigid Berlin Story," Shelly Dunn Fremont and Vincent Fremont's unsettling close-up portrait of Ms. Berlin, which opens today at the Film Forum. This fascinating but somewhat repellent documentary repeatedly contrasts interviews with Ms. Berlin filmed two years ago when she turned 60 with excerpts from the mostly black-and-white Warhol films in which she radiated the aggressive ferocity of a B-movie prison matron. Much slimmer today than in the Warhol years, Ms. Berlin, who lives on the East Side of Manhattan with two dogs, looks sleek and matronly at 60. But when she reminisces, it becomes clear that she retains a lust for the spotlight along with a continuing inability to edit what comes out of her mouth. As she chattily recounts a life of squandered privilege and wasted opportunity, the movie casts a bitter chill.

Hyperkinetic Children :: essays research papers

Hyperkinetic Children Hyperkinetic is just another word for Hyperactive. Hyperactivity describes children who show numerous amounts of inappropriate behaviors in situations that require sustained attention and orderly responding to fairly structured tasks. Humans who are hyperactive tend to be easily distracted, impulsive, inattentive, and easily excited or upset. Hyperactivity in children is manifested by gross motor activity, such as excessive running or climbing. The child is often described as being on the go or "running like a motor", and having difficulty sitting still. Older children and adolescents may be extremely restless or fidgety. They may also demonstrate aggressive and very negative behavior. Other features include obstinacy, stubbornness, bossiness, bullying, increased mood lability, low frustration tolerance, temper outbursts, low self-esteem, and lack of response to discipline. Very rarely would a child be considered hyperactive in every situation, just because restraint and sustained attentiveness are not necessary for acceptable performance in many low-structure situations. Many parents rate the onset of abnormal activity in their child when it is and infant or toddler. Abnormal sleep patterns are frequently mentioned, the child objects to taking naps, he also seems to need less sleep, and becomes very stubborn at bedtime. Then, when the child is seemingly exhausted, hyperactive behavior may increase. Family history studies show that hyperactivity, which is more common in boys than in girls, may be a hereditary trait, as are some other traits (reading disabilities or enuresis-bed wetting). Certain predisposing factors affect the mother, and therefore the child, at the time of conception or gestation or during delivery. Included are radiation, infection, hemorrhage, jaundice, toxemia, trauma, medications, alcohol, tobacco, and caffeine. The course of the syndrome typically spans the 6-year to 12-year age range. In many classrooms, children who display inappropriate overactivity (restlessness, moving around without permission) , attention deficits (distractible by task-irrelevant events, inability to sustain attention to the task) , and impulsivity (making decisions and responses hastily and inaccurately, interrupting and interfering with classmates and the teachers) are likely to be identified as hyperactive. The diagnosis of hyperactivity is usually suggested when parents and teachers complains that a child is excessively active, behaves poorly, or has learning difficulties. However, there is no specific definition or precise test to confirm that a child is hyperactive. This syndrome is most frequently recognized when the child cannot behave appropriately in the classroom. There are three characteristic courses. In the first, all of the symptoms persist into adolescence or adult life. In the second, the disorder is self-limited and all of the symptoms disappear completely at puberty. In the third, the hyperactivity disappears, but the attentional difficulties and impulsivity persist into adolescence or adult life.

Is Development Methodologies In Financial :: essays research papers

Introduction & Overview of the Company Marks and Spencers is a large UK based retailer with 683 branches in 2 continents. Following the deregulation of the UK financial sector in the mid eighties the company decided to use its experience, capital, and brand power to branch into the lucrative financial services industry offering personal loans, life insurance & pensions, and savings & investments services such as Unit Trusts and ISAs through the company Marks and Spencers Financial Services. Financial Services is now one of the fastest expanding areas of Marks & Spencers, MSFS employs more than 1,400 staff at its purpose built headquarters in Chester, and has dedicated financial services areas in 70 M&S stores across the country. The Information Systems department has 50 employees who come from analysis, design, & programming backgrounds, much of which has been gained with Marks & Spencers plc. The majority of these employees are based in the Chester head office, and systems are developed ‘in-house’. IS project s under development include the introduction of Individual Savings Accounts, with other likely future projects including telephone banking, credit cards, and auto/property insurance. The fact that MSFS has entered the Financial Services Sector comparatively recently and with a established IS knowledge base from the parent company has meant that existing information systems have been well developed in terms of technology and are compliant with the latest industry regulations. Therefore there is little or no need for redevelopment of existing systems in the short to medium term, and the ISD focus is almost exclusively on new market areas requiring Information Systems that can be started from scratch. The main exceptions to this are the possibility of introducing data warehousing to tap the potential of both MSFS’ and the parent company’s client database to better target MSFS customers, and the need to adapt existing systems for the introduction of the Euro, projects which will involve redesign of existing data stores and software. The company has grown very quickly, and IS projects have consequently grown considerably as can be seen by the size of the IT department. While there are still small to medium sized projects, some that are currently being considered will be on quite a large scale with several senior analysts working on each project. These projects are anticipated to require an IT department expansion of 50% over the next two years. Although MSFS’ IS projects share certain common characteristics in terms of their requirements, such as the need for a common ISD structure across projects, they vary considerably in size and strategic importance, with future developments looking likely expand those differences.

The Hukou System in China

No other creatures in the animal world form anything like cities. The closest resemblance would be a bee hive or an anthill, however in contrast to human agglomerations; they are closed to non-natives and not based on voluntary exchange (Bartlett, 1998, cited in O'Sullivan, 2009). The hukou (household registration) system, implemented in China in the late 1950's and still being enforced today, assigns a hukou location to every Chinese citizen that curtails self-initiated moves and limits migration from rural to urban areas (Fan 2005). These restrictions create agglomerations much ike those described by the hives and the hills of nature, and it is questioned whether such restrictions are preventing Chinese cities from obtaining a socially optimizing equilibrium. This essay looks to discuss the determinants of city size, the effects of the hukou system on these determinants and hence evaluate whether Chinese cities are induced to The size of a city can be distinguished between its size in terms of land mass and its size in terms of population. For this issue we shall mainly focus on population. Ravenstein's (1889, cited from Fan, 2005) laws f migration introduced the notion that people move in order to better themselves economically. In this view, migration is considered as the individual's response to regional differentials in economic development. Similarly, neoclassical theory views migration as an outcome of geographic differences in labor demand and supply (Sjaastad 1962, cited from Fan, Firms and hence labor force are attracted to cities as they provide agglomeration economies and economies of scale, efficiently concentrating infrastructure and other common resources via labor-pooling, knowledge pill-overs and economic competition, thus raising productivity, and hence wages (O'Sullivan, 2009). Ultimately it is a migrant's utility that influences their decision to migrate from place to place. O'Sullivan (2009) relates the utility of a worker with the total workforce within a city, From this example it can be shown that cities may be too large, but not too small. The utility curve reaches its maximum with 2 million workers in a city so a region with 6 million workers will maximize utility with 3 cities, where utility has adjusted until workers are indifferent between the two cities. If cities are too small, so for example if there are 6 small cities each with 1m workers, there is an unstable equilibrium because the utility curve is positively sloped at this point. If a worker moves from one small city to another they create a utility gap as the population in one has decreased – and hence utility – while the other increased. This gap encourages even more movement, and as self-reinforcing effects generate extreme outcomes, the extreme outcome is that everyone will move from one city to another, making the city ‘disappear'. However when you have two large cities, with m workers each, when a worker moves and a utility gap is created, utility is actually higher in the smaller city (perhaps due to congestion and overcrowding in the now larger city) making migration self-correcting rather than self-reinforcing. Migrants will then either move back to the smaller city, or existing inhabitants of the larger city will move to the smaller one until a stable equilibrium of 3 million workers. The hukou system's restrictions will limit worker's ability to migrate between cities and it is almost certain that an optimum equilibrium state will not being reached. Workers will be contained within the region they currently reside and while it may be possible for equilibrium to be reached within the region, it limits the probability of it being optimal dramatically. This reflects Andes'(1995) view that political forces, more so than economic ones, drive urban centralization, hence cities are induced While migration may be a major factor in the determination of city size, â€Å"cities are engines of economic growth† (Lucas, 2001, cited from O'Sullivan, 2009), regardless of migration restrictions. Krugman (1991) says that economic growth is induced through agglomeration economies, with lements of labor-pooling, knowledge spill-overs and technological innovation. With these elements, growth can be induced by increasing the productivity and income of human capital (O'Sullivan, 2009), learning and innovating production and management techniques from one another (Porter, 1990 cited from Glaeser, 1992) and hence as a result of a combination of the previous two, results in technological innovation, further increasing productivity and efficiency (Krugman, 1991). As a result of internal economic growth, O'Sullivan (2009) depicts this graphically again with respect to worker's utility and population, Figure 2. Growth induced by innovation shifts the utility curve outwards. People will then want to move to the innovative city and close the utility gap until a new equilibrium b and s. This however brings about an important point. The new equilibrium can only come about if labor migration exists. With the hukou system, migration is restricted which will result in innovative cities always having a higher utility than those who don't and hence because of such a disequilibrium, the majority of Chinese cities in effect are induced into being ‘too small'. The equilibrium j cannot be reached as nnovation cannot â€Å"become contagious† across cities, in which both cities will innovate at the same time. Jacobs (1969, cited from Glaeser, 1992) further supports the notion that internal economic growth alone is not sufficient as most important knowledge spill-overs come from outside the industry, and as a result of labor migration restrictions, such knowledge is limited to flourish growth. Scherer (1982, cited from Glaeser, 1992) presents evidence strengthening Jacob's view, indicating that around 70% of innovations in a given industry are used outside the industry. To summarize, labor mobility underpins the validity of O'Sullivan's theories on utility and population size within a city and the ideas of internally induced growth put forward by Lucas, Krugman, Glaeser and O'Sullivan. Without labor mobility, labor cannot close utility gaps, therefore not allowing the theoretical possibility for them to become too big, but not too small. A city's internal ability to induce growth is limited in Jacob's view if the majority of increases in productivity and innovation as a result of knowledge spill-overs arguably come from outside he industry, and hence city. The hukou system's power to restrict labor movement, restricts the possibility of â€Å"human containers shipping complex, uncodified information† (Storper, 2001) required for innovation from one interprovincial city to another, hence limiting the ability for growth. Chinese cities in effect, are forced into being ‘too small'. In conclusion, Myrdal (1957) argues a stable equilibrium assumption implies that a social process follows a direction, this in his view is wrong. It can be possible that some exogenous change has such strength and irection to bring the system to rest, however it is not a natural outcome and is furthermore unstable. Such a state can also be achieved through policy intervention – the hukou system in this case. Storper (1989) adds to this saying â€Å"growth is the pivot on which industrial geography turns, and change is the only constant in a world of persistent disequilibrium. Metaphorically, such an equilibrium (or disequilibrium relative to a less restricted system) resulting from the hukou system, contains provincial regions separately from one another rather than allowing a concoction give ise to a mass growing system. It can be argued however that smaller cities can be more desirable than those heavily under the influence of urban sprawl, exempting the dis-economies of increased congestion and commuting costs (Bruekner, 2000). But the strength and benefits of agglomeration economies in pushing cities to grow outweigh such by-products, as these can be addressed because of the innovation that is created. However, as discussed in this essay, there is much resentment against the hukou system. Huifeng (2010) presents a joint editorial in 13 Chinese mainland newspapers hat called on the nation's top legislative body to abolish the hukou system, as the strict population controls have split the country into rural and urban areas. He continues to say as the mainland has developed in recent decades, concerns have been expressed that the system may be doing more harm than good, with the divide between the urban and rural populations growing into a chasm. If the restrictions were lifted, a natural flow will be brought about onto the Chinese economy, allowing Chinese cities and regions to converge towards O'Sullivan's optimal equilibrium's, no longer rendering them ‘too small'.

Passion in Education Essay

What came first, the chicken, or the egg? A question in which many would say the chicken, because without the chicken, the egg wouldn’t be there. Others might say that the egg came first because chickens come from eggs, so without the egg, the chicken wouldn’t even exist. Its not the fact of which came first in this situation, rather than how they go hand in hand. Both the egg and the chicken need each other to be complete, just like teachers, and students. Teachers need students for educational purposes, and students need teachers to learn. The idea of â€Å"can there be education without passion? † is a debatable topic especially since some students might say that it’s the teacher’s job to make the class interesting and gain their interest. Teachers on the other hand might suggest that it’s up to the students to care enough about their education to motivate themselves to learn from the curriculum, no matter how tough, or dry the education may be. In the sense of coming together for a common cause passion is required to learn and succeed in school, but teachers also need passion to successfully teach their students. Patrick Sullivan, an English teacher at Manchester Community College in Connecticut, author of â€Å"A Lifelong Aversion to Writing†: What If Writing Courses Emphasized Motivation† expresses the idea that teachers need to attain the interest of their students and teach them the criteria in ways that the students understand it, and feel the need to learn it, but he also believes that the students themselves need to develop Intrinsic motivation. â€Å"Students who are engaged and motivated learn almost effortlessly. Those who are not almost always struggle, resist, and often fail. Unmotivated students also often become disruptive and troublesome influences in our classrooms† (Sullivan, 120 ). Students who put forth the effort needed to succeed in a classroom tend to do better than those who don’t. Without that inner passion to learn what a teacher is teaching, the student won’t learn. A teacher could come up with the best, most interactive lesson plan, but if the motivation isn’t there for a student, then all the teachers’ efforts are for nothing. Not all the blame can be put on the teachers. Some students just are not willing to learn, and continue with their education. College classrooms are filled with students who do not prepare for class. Many study less than 10 hours a week – that’s less than half the hours they spent studying 40 years ago. Paradoxically, students are spending more and more money for an education that seems to deliver less and less content† (Stuart Rojstaczer). Most students in college don’t put forth the effort needed to fully captivate everything a college class is giving, and it’s not because the education isn’t there, but that the students are not motivated to learn because they see that with little effort, they can pass their classes, and don’t need to study their brains out. The blame can’t only lie with the students either. Without teachers being passionate about teaching, then students won’t grasp the concept of what is being taught to them. â€Å"It is essential that English teachers begin to engage this research carefully and begin developing curriculum designed specifically to promote and nurture motivation† (Sullivan, 120). Without intrinsic motivation students won’t learn well, but it lies on the teachers as well to motivate students to want to learn, and to want to pursue their education. Students need to see where motivation can get them, for them to want to motivate themselves. Education is not the filling of a bucket, but the lighting of a fire. â€Å"The presence or absence of this â€Å"fire,† of course, affects everything students experience in classrooms† (Sullivan, 120). If teachers don’t make the class interesting and engage the students, then they won’t feel the need to motivate themselves to learn what is being taught. How they feel about the class effects how they learn. If they dislike a certain subject, they’ll always approach the subject with a bad mentality, and with that mentality, it will affect how they learn. In the attempt to attract students teachers have â€Å" loosen[ed] up. [They] grade much more softly than [their] colleagues in science. In English. [they] don’t give many D’s or C’s for that matter† (Edmundson). Students wont learn any better If teachers make the class easier, and in no way is that way of teaching ethical. Student’s wont try harder, or be more interested in the class. They will simply slack off even more and take the class as a joke. Teacher’s need to find a balance between making the class understandable, yet understanding. Dumbing it down, and passing students who don’t deserve the grade will make the class pointless and nothing will come from it. I have yet to find a teacher who teaches just to teach. They all want to make an impact on their student’s lives, and dumbing down courses wont help anyone. Neither the teachers nor the students are to blame for lack of passion in education. They both have to do their job as either a teacher who teaches English, or a student who is in an English class. The teacher has to engage the students to want to learn, and the student has to have motivation to want to learn what the teacher is teaching. If either of the jobs is lacking, then the likelihood of a student or teachers success is lower than if both were giving it their all. They both go hand in hand, and one wouldn’t be complete without the other just like the chicken and the egg. A teacher doesn’t teach an empty classroom now do they? They teach students for a reason, so that the students learn, but if the students are just sitting in the classroom, not paying attention or do not come prepared, then they might as well teach to thin air, because no one is benefiting from what the teacher has to offer.

A brief history of cosmetics Essay

Through the ages, cosmetics have been in used to transform appearances. It started with the Ancient Egyptians, Romans and Greeks (Avoncosmeticsnug 2007). In Ancient Egypt, exterior appearance is closely attached to spirituality (Mellor 2008). Looking good is not for vanity but for the gods. During those times, Ancient Egyptians used black kohl to color their eyes. It is a concoction made up of burnt almonds, oxidized copper, a couple of different-colored copper ores, lead, ash, and ochre. Kohl is applied using a stick and Ancient Egyptians applied it in an almond shape onto their eyes (Mellor 2008). For the lips and cheeks, a blend of red clay and water were applied, while henna was used on the fingernails (Narada 2008). This tradition behind cosmetics started to fade when the Greeks arrived and used cosmetics for aesthetic purposes (Mellor 2008). The use of cosmetics was widely accepted and it was a thriving commerce around the Mediterranean at that time (Narada 2008). Later on during the time of the Romans, perfumes were widely used in baths, fountains and also weapons (Boyd 2008). Romans also apply kohl just as Egyptians did (Narada 2008). As the nineteenth century ushered in, whitening mixture was applied on the face to be able to achieve a fairer complexion. During those times, whiter skin meant a good social status since darker skin is associated with the working class (Mellor 2008). This cosmetic was composed of carbonate, hydroxide, and lead oxide. But due to lead poisoning that caused muscle paralysis or death, lead oxide was replaced by zinc oxide which is still being used until today (Boyd 2008). Eventually by the 20th century, safer cosmetics were made available as doctors started to work with cosmetics companies to avoid problems like lead poisoning (Modes in Makeup 2008). The industry got a boost when cinema became popular and the masses tried to imitate actresses on the big screen. Helena Rubinstein and Max Factor both made their mark during this time as they developed an assortment of cosmetic products like mascara, colored powder, and pancake make-up (Boyd 2008). The new century also brought in a new trend – the tan complexion. Tan was now the symbol of affluent individuals who did not need to work but instead simply went outside and engaged in recreation. The bronze look was the look to go for (Modes in Makeup 2008). The industry continued to grow during the 50’s and the 60’s. Cosmetics companies advertise a great deal in televisions where the focus was on the lips and eyes. Natural products as well have grown in popularity. These are products with botanical components. By the 70’s, the concern for the environment was widespread and harmful ingredients were then banned for manufacturing (Boyd 2008). Many players now are part of this booming business. The industry will continue to grow as cosmetics continue to be an integral part especially of women lives. 2. 3 Branding Kotler (2003) defines a brand as any mark or label that is attached to a product that means something for people or something that people can be associated with. For example, coffee is a product and Starbucks is a brand that means high quality coffee and is usually associated with yuppies. In other words, a brand produces a certain image, feeling, emotion, personality, or even a set of values in a person’s mind by just hearing or seeing the brand’s name. For example, Coca-Cola connotes enjoying the moment of having a cool drink with friends or family, FedEx implies fast and safe delivery service, Porsche is expensive but luxurious cars, New York City is the city that never sleeps, and The Body Shop promotes the beauty of each individual while protecting the planet (Kotler 2003). Kotler (2003) further explains that building a brand involves an intricate and interdependent system of devices such as advertisements, public and media networking, financial support for events or issues, and many more. But the most important device is the customer service provided by the brand’s employees. Friendly and helpful shop employees may determine whether clients will come back or not. Everything about the company, its plans, processes, services, and final merchandise must revolve around the brand it is promoting. This is how valuable a brand should be for a company. On the other hand, to be able to say that a company truly has an effective brand depends on the level of loyalty and influence the brand has on consumers in general and on its clientele in particular (Kotler 2003). Specifically, branding is a marketing strategy of a business to make its product stand out among competitors. It uses tools like distinctive product names, symbols, slogans and other images (Principles of Marketing 2008). It not only helps in distinguishing a product but also safeguards the consumer from other products that seem to be the same (Hislop 2001). An example of a product with good branding is Nike’s sports apparels and shoes. The brand is strongly associated with sports and the checkmark sign and the slogan just do it sets it apart from other sports brands. Aside from familiarity branding also invokes emotional responses – Lexus with the feeling of luxury – or cultural responses – Pepsi with the youth (Hislop 2001). It was about 15 years ago when the concept of branding entered the business world. However, until now, the word is still being confused with marketing and advertising. The process of branding should be the first step followed by advertising under the big umbrella of marketing. Research shows that companies that do not establish a brand identity first before advertising only see themselves lose money (Klein 2008). Branding is not all about raising awareness to the product. It is about getting the consumers perceive the product as the sole answer to their troubles or needs (Lake 2003). The logo or slogan is not the brand of the company instead it is the character of the company. The brand is what the company symbolizes in the customer’s mind (Klein 2008). It is a summation of all the opinions and encounters of the customer with the product or service (Lake 2003). It is imperative for a company to establish a lasting brand if it intends to survive in the very competitive world of business.

8 Stages of Man

Cameron Roney Lifespan Development Eight Stages of Man Interview General question on childhood: I interviewed a seventy year old woman named Virginia that I met while doing my community service. I asked her to think about her first ten years of life and to describe times that she can remember being cared for. She said that it was her grandmother that did most of the caretaking for her, especially when she was sick. She recalled one time when she had a really bad sinus infection that her grandmother helped her through.When I asked her if she could think of any time she was not very well cared for, the only time she could think of is when her father would come home bombed, which sparked some intense arguments in the family. She recalled feeling very lost during these times. Fun times in her childhood consisted of time with her family since she did not have any friends as a child. Specifically, she remembered having a lot of fun planting pumpkin seeds with her family. Trust vs. Mistrust : I asked her to describe her relationship with her parents. She said they were very close, and she went hunting with her father often.She got a lot of adult attention. She considered herself to be pretty self reliant and optimistic despite her loneliness. She feels that her seclusion from children her age was a big factor in developing her independence and self reliance. She was trustful of her parents and family, and trustful in herself to deal with most problems that arose in her life at that time. Autonomy vs. Shame/Doubt: Virginia reported to be fairly active, and she is. She runs a local community donation center and does a great deal of work for her church. She describes herself as self reliant.When looking back, she does not feel that she relied on others very much. She considered herself to be adventurous, but not careless. She was not overly fearful, but she wasn’t overly risky either. All in all, she is a very active woman for being seventy years old. Initiative vs . Guilt: When I asked her about her efforts to stay active, she spoke about her work involving the construction of a new church, her being the chairman of the building committee, and her work at the community donation center. She does a lot to help care for her mother and helps her children when she can.She says that all of this is a handful, but she enjoys the activity. She says that when she was younger she did consider herself to be a creative person and could think outside the box. She is an extremely able bodied woman for her age. Industry vs. Inferiority: I asked her to describe her career and her accomplishments. She recalls her thirty five years as a physical therapist. She considered it her responsibility and calling in life. She talked about one boy in particular that she worked with who lived out of town.She worked with him for three years because no one else could reach him. When I asked her about times when she felt that she had been competent and productive and develop ed her skills. She recalls doing a lot of odd jobs which taught her a lot of new skills. She found creative ways to solve problems unique to the different fields she worked in. When I asked her to describe some times that she felt incompetent or ineffective she talked about times when she would overburden herself with too many jobs or trying to handle an extremely large workload herself.She considers herself competent and capable, and really has accomplished a lot in her time. General Question on Identity: I asked her to think about her encounters with her peers when she was between 10 and 19 years of age. She said that she was not so accepted by those around her. She was overweight as a kid. She moved to a new high school which was in a city. This was tough on her because she had grown up in a very secluded setting and she lagged socially. She considered this a huge cultural shift for her. She felt very lost and really had a hard time finding herselfIdentity vs. Identity Diffusion: When I asked her about her experiences as a teenager trying to find herself and who she was and what she wanted out of life, she said that she had always wanted to help people. She wanted to be an architect for the longest time, but she was discouraged when her sister got very sick and saw the therapy she went through. She said that is when she decided to become a therapist. She says that she has a very strong sense of who she is and what her purpose is now. She also says that she is fairly headstrong and not easily influenced by others.To sum up, she has a strong sense of identity. General Intimacy Question: I asked Virginia to think back to her twenties and thirties and the experiences with imported others in her life at that time. She said she had a lot of support and encouragement from those close to her. She was not dependant, but it definitely helped her through some rough times in her life. Intimacy vs. Isolation: I asked her to describe her marriage, and this is where the b ulk of the interview took place. She said that her marriage was rough at first.Her husband was an ex-marine who killed 14 men during his time in the military. He was introverted and very little communication took place between them. It took him thirty years to open up to her. She says that the last years of their marriage have been the most rewarding. Her only sibling died when she was eighteen, but when she was alive they were very close. She was teased a lot, although there was not much fighting between them. They relied on each other for fun which brought them very close together. I asked her who she felt the most comfortable confiding in.She said that she only really felt comfortable confiding in her grandmother and father, but they have both passed away. I asked her if there was anyone close to her that she felt she couldn’t really open up to. Aside from her husband until the later part of their marriage, she talked about her children. She has four, and of all of them th e oldest is the most independent. This caused a lot of friction between them during his adolescents and young adulthood, but they have since grown closer. Her third daughter has been diagnosed with social anxiety disorder and she has spent a lot of time trying to help her open up.In my opinion, the only time that she has had any real intimacy with those close to her was during her early childhood and late adulthood. Most of her life between those times she seems to have been pretty isolated. General Generativity Question: I asked her to reflect on her life from ages thirty to sixty five. I asked her to describe he experiences of taking care of others around her. This was a pretty depressing part of the interview. She said that she often felt inadequate as a mother. She says that she should have gone another direction regarding the way that she brought them up, and that she often regretted having children.She is now pretty involved with her children, and she helps her youngest daught er financially. She gives advice when she is asked. She has definitely taught and helped her children, but I think that it is pretty clear that she lacks a feeling of generativity. Generativity vs. Stagnation: I asked if she feels that she has done enough to have a positive impact on those around her. She feels that from her experiences she has learned to do better and guide gently. She considers herself to be pretty understanding. I asked her in what ways she has tried to pass along her knowledge.She says that she has passed her knowledge along to her children, and she has done a lot of work with juvenile offenders in her community service. She says that she always tried to accept them for who they were, regardless of what they were dealing with. Regarding generativity, she has had a hard time with it, but she feels that she does a lot better now that she has her experiences to draw back to. General Question on Integrity: I asked her about her lifestyle compared to others, and she said that she lives a relatively laid back life. She is fairly chilled out and relaxed. She tries to do her part, but she does not feel pushed.I asked her about how she felt about her mortality. She said that she is not joyous about it, but she is accepting. She finds comfort in her faith. Integrity vs. Despair: I asked her about her current goals. She says that she strives to stay active, she wants to learn to play the piano, and she wants to lose twenty pounds. She feels comfortable about her life and the decisions she made. When I asked her about her opinion about the future of the united states, she said that she is very pessimistic about President Obama, the recession we are experiencing, and the national defeciet.

Physiology – Rabbit Ileum

The isolated intestinal smooth muscle preparation is one of the classical preparations in physiology and pharmacology for bioassays, or the study of drug action and autonomic control of motility. This preparation is included in many â€Å"in-house† laboratory manuals of various colleges and universities around North America, and in some commercially prepared manuals deal ing with physiology and pharmacology (e. g. Nicpon-Marieb, 1981).Basically, the method presented in this report is a modification of the original Finkleman preparation (Finkleman, 1930) for the study of the autonomic control of intestinal motility. What is different about our approach is the method of mounting the preparation and the method of stimulation of the sympathetic nerve. The classic way of mounting the piece of intestine is to suspend it vertically in a muscle bath between an aeration tube and a recording lever.The problems with this technique are (1) stress placed on the intestine when the chamber i s emptied during the process of changing solutions, and (2) difficulty in stimulating the sympathetic nerve due to the fact that the preparation is totally submerged in a physiological saline solution. We have overcome these problems by mounting the segments of gut horizontally in a shallow muscle bath. As a result, less stress is placed on the intestine during changeover of solutions, and it is easier to manipulate and to stimulate the sympathetic nerve contained within the mesentery.Also students find i t much easier to mount the preparation in the horizontal bath and are less likely to stretch the muscle preparation in the process. With these modifications we have improved the student success rate from 50-60% to 90-100%. Large recordings of the muscle contraction, such as those shown in Appendix A, are easily obtainable using a kymograph and simple lever system. In fact, another advantage of this exercise is that it does not require expensive recording equipment.
