The difference is profitability among the three courses can be attributed to the differences in the fees charged per EFTSL and the amount of government grant received per EFTSL. The student fee per EFTSL is highest for the Law course and lowest for the economics course. In fact, the student fee for the Law course is $6,000 or 67% more than the economics course and $5,000 or 50% more than the Accounting course. The government grant per EFTSL for the Economics course is $1,000 or 40% higher than the Accounting course and $1,000 or 17% more than the Law course. In total the Revenue per EFTSL for the Law course is $6,000 or 40% more than that for Accounting and 31% more than that for Economics. ... It is described as a complex and comprehensive process which requires careful and systematic analysis to determine different cost pools and activities that relate to them. This makes the implementation of an ABC system a very costly and time consuming exercise (Estrin at al 1994). According to Horngren et al (2011) ABC is one of the best tools available for improving a costing system. Some of the reasons given include the following. i. ABC emphasises individual activities as main cost objects – each activity having a specific purpose while traditional costing systems do not (Horngren et al 2011) ii. ABC calculates the cost relating to each activity and assigns costs on the basis of the activity which led to the production of the service or product and this leads to higher levels of accuracy when compared to traditional methods like absorption costing (Horngren et al 2011) iii. ABC systems facilitate more favourable pricing and product-mix decisions (Horngren et al 2011) iv. AB C enables decisions relating to cost control by providing information that facilitates process improvement and product design (Horngren et al 2011) v. Studies have found that some level of success is achieved when ABC is implemented which leads to improvements in both manufacturing and business performance (Fei and Isa 2011) vi. ABC provides results that are very different from those generated from less costly methods. However, the information provided can lead to major decisions that impact profitability and other important aspects of the business on which it depends (Estrin et al 1994).

Study on the effects of occupational therapy

Study on the effects of occupational therapy Occupational therapy (OT) is about helping people of all ages conduct and improve their ability to perform their daily activities that occupy their time in their environment (Hussey, Sabonis-Chafee, OBrien, 2007). The environment to which individuals may wish to perform tasks could be in home, work, school or community settings (Hagedorn, 2000). The roles of occupational therapists (OTs) are to work with individuals to help them achieve a fulfilled and satisfied state in life (Crepeau, Cohn, Schell, 2009). Activities or interventions may be used to achieve functional results that promote health, prevent injury or disability so that individual may become independent as a result. OTs work with a range of people that may have conditions that are mentally, physically, developmentally, socially or emotionally disadvantaged (Crepeau, et al., 2009). Therefore they help individuals to develop, recover or maintain their skills to be able to conduct activities that they deem important. The reason why OTs wants to find out about a persons occupation is to determine what is important to the individual and how they may conduct these occupations and how all these occupations contribute to the greater good of health. A persons occupational performance is influenced by their health and the need for personal satisfaction in what they do (Crepeau, et al., 2009). This is why OTs may conduct interviews before implementing interventions. It is a way for OTs to collect informed information regarding to the needs of individuals and what they find important in their lives. The initial interview would be about gathering basic information about the individual and going through name, age, occupation and what important roles they have in their lives. As OTs, it is very important that focus is client-centred and allow clients to evaluate their performance and the importance of roles in their lives. The Person-Environment-Occupation-Performance (PEOP) model is a client-centred model that is used to improve the performance of individuals in their daily lives (Christiansen Baum, 2005). The model was developed in 1985 and was first published in 1991. The PEOP model includes the interactions of occupation, performance and participation that are involved between the person and environment when they carry out their activities in their daily lives. The model talks about the personal factors and environmental factors that support enable or restrict the performance of individual to their activities, tasks and roles that are present in their lives. In the PEOP model, OT intervention is a method of using a wide range of client-centred strategies that connect the individual or group to develop or use sources that enable them to successfully perform necessary and significant occupations. It takes into account that satisfaction of performing occupations is related to the individual or group goals and environmental factors that may or may not inhibit participation. The PEOP model has four major components. These four components are occupations, performance, person and environment (Christiansen Baum, 2005). It describes what people want or need to do in their daily lives (occupation), the act of performing the occupation (performance), and how psychological, physiological, neurobehavioral, cognitive and spiritual factors (person) combine with the location the occupation is conducted (environment) influence success. The individual ability or skills is what determine whether the individual is competent to do what they must to meet personal needs. The individual must make use of resources that are available within the environment to effectively meet these needs. The model also has the belief that the situations where people feel success also help them feel good about themselves. Therefore it acts as a motivator to allow individuals to face challenges with confidence. It is said in Christiansen Baum, that fulfilment comes both from feelings of mas tery as well as the accomplishment of goals that have personal meaning (Christiansen Baum, 2005). This indicates that individual will feel more accomplished doing occupations that they like doing and is important to them, rather than something they dont find important. According to Henry Kramer, interviewing is a shared verbal experience, jointly constructed by the interviewer and the interviewee, organized around the asking and answering of questions (Crepeau, et al., 2009). Asking good questions is not a natural phenomenon and requires practice (Miller, 2009). This is why communication skills are essential in interviewing. Interviewing requires three key elements, questioning, active listening and interpreting body language (OToole, 2008; Williams, 1997). The aim of an interview is to collectively obtain information, offer advice, support and discuss treatment (Williams, 1997). Through the process, OTs is able to establish and maintain a relationship with the client. It is important in any interview to be prepared and consider that the location where the interview will take place will set the mood. If the interview is conducted in an office, it can give feeling of formality and if the interview is conducted in a clinic, it can be associated with illness. Individuals response to these different settings may be associated to previous experiences that they may have encountered in the past. Their reaction can vary and as an interviewer, awareness should be recognized. The location of the interview can also give the purpose of the interview so it is important that suitable location be chosen. There are three phases to an interview; phase 1 is the introductory phase, phase 2 is the working phase and phase 3 is the termination. Effective communication requires mutual understanding from both interviewer and interviewee. Health professionals must ensure that clients understand the meaning and purpose of interview and why it is conducted. The interview requires that information be shared, there is a goal to reach same understanding, understanding of background and culture, a willingness to understand points of view, respect for self and other and show empathy when appropriate (Higgs, Ajjawi, McAllister, Trede, Loftus, 2008). Communication skills required in an interview include verbal communication, non-verbal communication and active listening. An example of verbal communications is the effective use of speech to ask appropriate questions and the structure of language used (Williams, 1997). The structure of the language is the way that words are put together to form sentences to give information or seek information. Verbal communications are ways of individuals expressing their ideas, concepts and emotions, give description, provide information and solve problems (OToole, 2008; Stein-Parbury, 2006; Williams, 1997). Non-verbal communication is communicating without using words to express oneself. These could include eye-contact, facial expression, body postures and behaviours, voice and volume alterations and physical space (Egan, 2007; OToole, 2008; Stein-Parbury, 2006; Williams, 1997). Active listening requires interviewer to actively listen and give verbal and non-verbal responses to show that they ar e listening. Interviewer can use non-verbal responses known as SOLER to engage in the interview. SOLER stands for sit squarely, open posture, lean toward the client, eye contact and relax. Prompts can also be used in non-verbal response to encourage interviewee to talk further or know that you are present. Verbal response includes using the three Rs; restatement, reflection and re-clarification. Phase 1 of the interview is the introductory phase. This is where introductions and purpose of the interview is explained. Permission was asked to use clients first name to be more comfortable and to create a relax environment. In this phase of the interview, the client and interviewer is sitting squarely facing each other in a small quiet room. The client is actively listening to the information told. Her actions included eye-contact, sitting squarely, using prompts such as nodding and yep as indications. There was a bit of closed postured, clasped hands and fidgety shown by client at the start that could be attributed to nervousness and uncertainty of interview. As the interviewer, verbal communication is essential in relaying the information about the purpose of the interview. This is where effective verbal communication comes into play. Effective use of speech was present but the structure of language needs to be improved. After explanation of what an OTs does, interviewer asked Do you kind of get what Im trying to say? in an uncertain voice. Interviewer could have rephrased it in a more confident reassurance voice and asked if the client understood the information and whether shed like to ask any questions. The style of language used here could be differences between social contexts. The use of formal language may not be used frequently in daily lives which make the interviewer structure of language seem a bit informal when asked. Being unsure of your own questions also leads client to perceive that it was okay to agree since it is an uncertain question. The object of an interviewer is to be confident and be able to express clearly and concisely the questions asked. Interviewer showed facial expressions and hand gestures while explaining. This could be an indication of nervousness or a habit that the interviewer may possess. Even though eye-contact was made with client, SOLER was not effectively used. At the start, interviewer is sitting squarely, leaning forward and maintained eye-contact but was not in an open relaxed posture. This was attributed to nervousness as interview progress; interviewer became more open and relaxed. Phase 2 of the interview is involved in asking relevant questions to get a clearer picture of clients occupation and history. It is where most information is collected and requires the use of a range of communication skills. SOLER was maintained throughout the interview by the interviewer and verbal prompts was used at appropriate situations to verify information that client had said. Nodding and hand gestures were used quite often to encourage client to continue talking and sharing information. In an interview, a range of questioning style is used. An example of an open question is How do you feel having to travel one and half hour to get to uni? These types of open questions allow clients to elaborate more on details and give indication to their emotions. Even though closed questions are not desirable, interviewer did make use of them. One of such is How long do you drive to uni? There is only one answer possible and does not make use of client views or feelings in this situation. Probing questions was also lacking in this interview, interviewer did not make use of this questioning style to seek out specific information. One example that is viewed is Is that the only problem you have as being a student? The question is used to question client whether the particular problem given was the only one present to being a student. Reflective questions was used to reflect a topic back for clarifications, So far youve told me that you are a student, girlfriend and you also like to keep active, is there any other activities that you enjoy doing? Some bad examples of questioning styles that should be avoided that was used in the interview was multiple and leading questions. Do you have any other career path you want to take after studying this degree? Or do you want to just find a job afterwards and be happy with that? The questions does not allow client to answer and also leads them to answer in a certain way that you have asked. Non-verbal communication skills is seen in eye-contact, facial expression, gestures, body postures and head movements. Throughout the interviewing process, eye-contact was maintained in client and interviewer. In some culture, eye-contact is not seen as appropriate when talking to elders (Crepeau, et al., 2009). Eye-contact can also become uncomfortable if used with strangers and you are expected to maintain focus for a period of time. As OTs, it is appropriate to keep an open view of clients and know that depending on their culture and values, they may conduct and act in different ways. Facial expressions on the other hand are what characterise a person. It is an important aspect of expressing emotions and expressing how we feel. Client used smile as a positive feedback when talking about her family and boyfriend. It is indications that these are the things that the client values and find enjoyment in. When she was unsure of her answers, her eyebrows would be raised upwards. Facial expression belongs to individuals and each person has their own way of expressing themselves. Gestures are also a form of communication and are seen in the movement of head, hands and body parts. It just acts as ways that individual may use these parts to emphasise and reinforce information. Body postures refers to the position of the body and limbs (Williams, 1997). The postures adopted by the client was slightly leaned forward back with arms placed together in front of her laps. The interviewer on the other hand has her body leaned forward towards the client and arms resting on legs to cater for the book in front of her. The importance of postures can give indications to individual emotions. A slump shoulder and crossed arms could indicate lack of interest or boredom. Phase 3 is the termination where information is summarized and clarified, client is thanked and ending of interview. Interviewer successfully used all mentioned techniques in this last phase but the language and structure of speech used could be improved. This could come with practice and experience. The voice used in the interview also gives indication to the emotions that is conveyed by clients and should be picked up when possible. The rate of speech or tone of voice express emotion and convey information about attitudes to certain things. Each individual have their characterised voice that distinguished us from someone else. It is with our voice that we can allow our emotions and feelings be conveyed. Interviewing requires multiple communication skills and practice to execute a good interview. Communication skills are not always verbal but include the non-verbal communication that is expressed through facial expression, gestures and eye-contact. Each individual have their own way of expressing themselves whether verbally or non-verbally. It is a good interviewer that is able to pick up on cues to allow them to adjust to client when interviewing. Interviewing requires interviewer to actively listen, question and empathize with clients. Through the use of PEOP model, the interview is able to be carried out and informed information is collected on the person, occupation, environment and performance.

Pollution and the Environment Essays -- Environmental

Pollution and the Environment Pollution occurs when harmful substances or products are introduced into the environment. It is a major problem in America, as well as the rest of the world. Pollution damages the environment and does harm to humans and other animals. It creates many problems, from lung cancer to the greenhouse effect. Oblivious to the damage they cause, rednecks continue to throw trash out of the window instead of walking two feet to a garbage can. The laziness of these types of people creates problems for the entire planet. People must realize that something needs to change. Why does our world continue to become more polluted year after year?   Ã‚  Ã‚  Ã‚  Ã‚  Obviously, most pollution comes from automobiles. The most famous pollutant from cars is the exhaust. The fumes given off as a byproduct of the engine slowly damage our lungs and the atmosphere. The exhaust is also toxic to human beings. Cars produce a large amount of noise pollution as well as a large amount of heat. Despite all the damage caused by cars, no significant progress has been made to change their destructiveness. People call the car ‘‘progress’’: an improvement on our daily lives. However, making a sport out of destroying the environment as NASCAR does cannot be justified as progress.   Ã‚  Ã‚  Ã‚  Ã‚  Another major source of waste is garbage. Americans throw away millions of tons of garbage each year. There are projects underway to clean and reuse this trash, but most of it ends up in huge landfills. ...

Economics-Sectors of the Indian Economy

CH-2-ECONOMICS-SECTORS OF THE INDIAN ECONOMY Chapter –2—Economics SECTORS OF THE INDIAN ECONOMY In order to understand the functioning of any economy, we need to study various sectors that it comprise. All around us we find people engaged in different types of activites. CLASSIFICATION OF THE ECONOMIC SECTORS: The classifications are based on 1. Nature of activity being performed. —Primary, Secondary & Tertiary 2. Working conditions of the workers—Organised & unorganized. 3. Who own the assets/ on the ownership basis. —Public & Private PRIMARY SECTOR:  1. Activites undertaken by directly using natural resources. . Example—Agriculture, Mining, Fishing, Forestry, Dairy etc. 3. It is called primary sector because it forms the base for all other products that we subsequently make. 4. Since most of the natural products we get are from agriculture, dairy, forestry, fishing it is also called Agriculture and related sector. SECONDARY SECTOR: It cov ers activities in which natural products are changed into other forms through ways of manufacturing that we associate with industrial activity. 2. it is a next step after primary, where the product is not produced by nature but has to be made.Some process of manufacturing is essential, it could be in a factory, a workshop or at home. 3. Example: Using cotton fibre from plant, we spin yarn and weave cloth; using sugarcane as a raw material we make sugar or gur; we convert earth into bricks. Since this sector is associated with different kinds of industries, it is also called industrial sector. TERTIARY SECTOR: 1. These are the activities that help in the development of the primary & secondary sector. 2. These activities by themselves do not produce good but they are an aid and support to the production process. . Example: a)Transportation–Goods that are produced in the primary sector need to be transported by trucks or trains and than sold in the wholesale and retail shops; b) Storage–at times it is necessary to store these products in godowns,which is also a service made available. c)Communication –talking to others on telephone); d) Banking–borrowing money from the banks. 4. Since these activities are generate services rather than goods it is also called Service sector. Q. How do we count the various goods and services and know the total production in each sector?As thousands of goods and services are produced, it is an enormous task to add up all these. To get to this problem economists suggested that the value of goods and services should be used rather than adding the actual numbers. But only one precaution is to be undertaken ie. , only final value of the goods and services should be counted as it already includes the value of all intermediate goods. GDP—  The value of final goods and services produced in each sector during a particular year provides the total production of the sector for that year.And sum of productio n in three sectors give Gross Domestic Production—GDP of the country. –It is the value of all final goods and services produced within the country during a particular year. –GDP shows how big the economy is. Q. Who measures the GDP in India? This mammoth(huge) task in India is carried on by the Central government ministry , with the help of various govt. Departments of Indian states and union territories. The information relating to total volume of goods and services and their prices is collected and then estimates the GDP. Historical change in the sectors: three stages. INITIAL STAGE:After observing the changes that have come in the development patterns of the sectors, it has been found that – in the Initial stages of the development the Primary Sector was the most important sector of economic activity. -As the methods of farming changed and agricultural sector began to prosper, it produced much more food than before and many people could takeup many oth er activities which led to the increase in number of activities. -However at this stage most of the goods produced were natural products from the primary sector, hence most people were employed in this sector. SECOND STAGE: Over a long time(more than hundred years or so) because new methods of manufacturing were introduced, factories came up and started expanding. -People began to work in factories in large numbers, and also people started using factory goods in large numbers as they were cheap. -Secondary sector gradually became the most important in total production and employment. There was a shift and the importance of the sectors also changed. THIRD STAGE: In past hundred, there has been a further shift from Secondary to Tertiary sector in the developed countries. -The service sector has become the most important in terms of total production.Most of working people are also employed in the service sector. Q. What does the history of developed countries indicate about the shifts that have taken place between sectors? (book question) It indicates that both secondary and tertiary sectors are developing and are becoming major contributors of the GDP. -This shift has come up with the improvement in the agricultural sector, people now had more time for other activities and the number of craft persons, traders (SECONDARY) increased and also buying and selling activities also increased . Now there were many transporters, administrators, army etc. TERTIARY) Rising importance of tertiary sector in production: Over thiry years between 1973 and 2003, production in the tertiary sector has increased the most, and it has emerged as the largest producing sector in India replacing the primary sector. Q. Why the Tertiary sector is becoming so important in India? There are several reasons to it: 1. In any country several services such as hospitals , educational institutions, post and telegragh services, police stations, courts, village administrative offices, municipal corpo rations, defence, transport, banks, insurance companies etc. are required.These services are called the’ Basic services. ’ In the developing countries the government has to take the responsibility for provision of these services. 2. The development of the agriculture and industrial leads to the development of services such as transport, trade, storage and the like. Greater the development of primary and secondary sectors more will be demand of such services. 3. As the income level rise, certain sections of people start demanding many more services like eating out, tourism, shopping , private hospitals, professional training etc. This is found especially in the big cities. 4.Over the past decade or so certain new services such as those based on the information and communication technology have become important & essential. INDIAN SECTORIAL GROWTH: It is a remarkable fact that while there has been a change in the share of three sectors in GDP, a similar shift has not tak en place in employment. –Service sector in India employs many different kinds of people—at one end there are a limited number of services that employ highly skilled workers and on the other end there are a very large number of workers engaged in services such as small shopkeepers, repair persons, transporters etc.Hence only a part of sector is growing in importance. — More than half of the workers in the country are working in primary sector, mainly in the agricultural, producing only a quarter of GDP. In contrast to this secondary and tertiary sector are producing three-fourth of the produce whereas they employ less than half the people. Q. WHERE ARE MOST OF THE PEOPLE EMPLOYED? WHY? The primary sector employs the largest number of people in India. –It is because not enough jobs were created in the secondary and tertiary sectors. Q.Even though primary sector employs largest number of people yet its share in GDP is less. Why? –More than half of the workers in the country are working in primary sector, mainly in the agricultural, producing only a quarter of GDP. In contrast to this secondary and tertiary sector are producing three-fourth of the produce whereas they employ less than half the people. –This also means that there are in agriculture more people than necessary and even if we move a few people out, production will not be effected. In other words, workers in the agricultural sector are under-employed.UNDER-EMPLOYMENT: It is a situation, where people are apparently working but all of them are made to work less than their potential. –if few people move out , it will not effect the production. –it is hidden in contrast to the open unemployment where a person is clearly or visibly without job. –it is also called disused unemployment. –this underemployment also happens in the other sectors for example there are thousands of casual workers in service sector in the urban areas as painters, plumbers, repair persons etc. HOW CAN WE CREATE EMPLOYMENT? There are various ways in which govt. an create employment opportunities as†¦ 1. The govt. can spend some money or banks can provide loans to construct well ect. Which will reduce the dependency of farmers on rains, and they will be able to grow two crops a year. 2. Construction of Dams and Canals can lead to lot of generation of employment in agricultural sector itself. 3. If govt. invests some money on transportation and storage of crops or makes better rural roads, it can provide productive employment not just to farmers but alsoto other who are in services like transport or trade. 4.If local banks give credits at reasonable rates to the small and marginal farmers ,they will be able to buy necessary inputs for their crops in time. 5. Another way to solve this problem is to identify , promote and locate industries and services in the semi-rural areas where a large number of people maybe employed. Example:many farmers grow arhar &chickpea for them a dall-mill to procure and process these & sell in the cities;opening a cold storage will give an opportunity to thefarmers to store their produce like potato &onion and sell them price is good; villagers near forests can start with honey collectionect. . To improve health situation we need health centres, hospitals & for that doctors, nurses, workers. 6. Similarly to provide education to all children we would need lot of schools which can also generate employment. 7. Tourism:every state or region has the potential for increasing the income and employment for people in that area. This can also be done by promoting tourism or regional craft industry. 8. News services like IT are also creating jobs.All these are the long term projects but govt also has certain short term projects for people as:NREGA-2005. NREGA—2005 –National Rural Employment Guarantee Act 2005. –started by the Central govt. — made a law implementing Right to work in 200 districts of India. –all those who are in need of work will get guaranteed 100 days work and if the govt. fails to do so, it will give unemployment allowances to them –the work will of the type which will in future help to increase the production from land.

The toy mobile is around fifteen inches away from the child because the child c an see that far. At the age of three months, the baby’s visual ability is limited since they can only see objects within a fifteen inches diameter as afore mentioned, which is why, the mobile toy is hung at such a level that the baby will not see blurred images and items. The soft keys or rather key pads help in the development of the infant’s sense of touch. Owing to this fact different fabrics are chosen to provide the soft and smooth texture of the toy. At this age, the baby has opened his fist and almost every now and then, it plays with the feet using the opened fist in a grabbing manner. Hard fabrics will scare the child away from holding things because the child’s hand has just opened up to grasp things and thus it’s very soft and tender thus the muslin square material serves the purpose. This stimulates touch and increases the child’s alertness and attention span. The toy mobile has dangling toys that dangle in such a manner that the child is made to lift its head and chest as if doing some push-ups. This contributes to the active behavior of the child and enhances its back’s strength. Additionally, the dangling makes strengthen the child’s neck. While dangling, the toys rattle making some noise that the child responds to by laughing or cooing. Moreover, the toys are made of small sizes to ensure that the baby can hold them, an aspect that enhances the development of the muscles within the infant’s hand. The smaller the size of the toys, the easier and faster the child’s hand will develop as far as holding is concerned. The child at this age is changing toys from one hand to another. The mobile toy has multiple features that are close for the baby to grab with ease and comfort. This action enhances the child’s cognitive ability to pass objects from one hand to the. Furthermore, being able to reach for the toys will enhance coordination skills in the child that add up to cognitive abi lities.Advertising We will write a custom essay sample on Early Infancy: Benefits of the Toy Mobile specifically for you for only $16.05 $11/page Learn More The child at this age is making some funny noises and thus for verbal stimulation, the toy is able to make some sensible noise which aids in the child’s development. The accidental squeaks will help the child become more aware of what the hand is doing. Additionally, the ability of the toy to play different tunes of music enables the child to become more vocal. The music needs to be played from time to time with different tunes for the baby to useful acquire and learn different tunes. The mobile’s position should be changed from time to time to allow the baby to get a new view and sharpen its memory when trying to locate moving. This is made possible by the fact that it has an adjustable swiveled arm. The toy mobile has some soothers that help the child a lot as far as sleep is concerned. It can also be used to regulate the infant’s behavior. For instance, when the soother plays some gentle music on a repeatedly slow tune, the child goes to sleep. This makes it possible for the sleep patterns to be monitored. When it is time for the baby to sleep, using the toy mobile can ease the caretaker’s task. In enhancing the child’s ability to focus, the baby sitter can point at the different lights produced by the toy. This in return enhances the child’s visual ability as well as the child’s memory. Switching through the music and finding one that soothes, helps the child learn and adapt to the music for sleep. With this, the child can easily adapt to the outside environment. The squeaking sounds sharpen the child’s hearing ability and the child will follow sounds made from different directions in the toy mobile. Colors and high-contrast patterns are a great way to stimulate the babys visual sense. Bright colors are easily visible and that is why the toy mobile is made of bright colors that enhance sight ability. Additionally, the sweet scent in the crib boosts the smell sensory skill. The yummy taste boosts the child’s ability to the sense of taste. Additionally, the size of the toys plays a very critical role when it comes to taste because the child will grab a toy and take it straight to its mouth and if very small, it will be swallowed harming the baby. Babies prefer viewing human faces and this makes him laugh with them. The mirror gives the child the impression that there is someone teasing him/her for at this age the child cannot know that he is the same in the mirror. This boosts visibility and the memory in return. The activity mat laid on the crib for the baby to sit on helps the baby during the tummy time where the baby lifts and tries to lift its legs. This boosts its fine motor skills. The texture of the mat is very useful in preventing bruising of the baby while doing the semi push-ups while lying on its tummy.Advertising Looking for essay on anthropology? Let's see if we can help you! Get your first paper with 15% OFF Learn More In essence, the toy mobile manufactured helps the child a great deal during its growth. The skills to taste, see, hear, smell and touch have been taken care of by the music, the bright colors and contrast pattern, the scented crib, the soft toys among other characteristics of the toy mobile. This makes it easier for the child to move to the next level with enthusiasm and great fitness. The toy enhances the development of the child in all ways possible. In conclusion, the toy mobile manufactured is a blessing to the mother and the child as well. The benefits it accrues them both are immeasurable. It stimulates the infants sensory, biological and cognitive abilities as discussed above. The nervous system, as a major concern, is developed by the fact that the toy mobile allows the child to move from one state to another with ease. Giving the baby stimulating experiences will help it to develop its brain and lay the foundation for more advanced learning later on as far as the babyâ€⠄¢s sensory, biological and cognitive abilities are concerned. Once one stage of life is well and healthy, the next one becomes easier to undertake. Thus, the three month old baby grows healthy courtesy of the toy mobile.

Free Essays on Ottoman Empire Overview

The Ottoman Empire: Focus on Society By the 16th century, the vast and mighty empire of the Ottomans had reached the zenith of its power. The lands under Ottoman rule stretched from the heart of Central Europe to the deserts of Arabia. In nearly every respect, the Ottoman Empire was strong and well-organized. As such, it comes as no surprise that the people under Ottoman rule were organized in a neat power structure as well. From the royal Sultan to the villagers in the rayyah class, the people of the Empire each had a unique position in Ottoman society. At the very top of the pyramidal societal structure was the Sultan, absolute commander of all, and executor of decisions concerning politics and state wealth (for the purposes of serving the state's interests). A step below the Sultan were a small group of wealthy, esteemed leaders, who were ascribed special status because they were essentially the Sultan's "slaves". The main duties of this select little group were to protect and enlarge the financial assets of the state for the benefit of the Sultan and the Empire. These leaders also ruled and defended the far-flung Ottoman Empire. While the Sultan invested wealth and the leaders protected it, the majority of commoners, the rayyahs, had the task of actually producing the wealth. The rayyahs had to pay part of their profits from industry, commerce, and farming to the state in the form of taxes. Townsfolk, villagers, and pastoral peoples made up the eclectic mix of the rayyah class. The word "rayyah" literally translates into "the protected flock of the Sultan". While Ottoman society was clearly divided into distinct social classes, these classes were neither closed nor confining, meaning that with the proper attributes and luck, a man could raise his social status.

Challenges To Singapore’s Education

Challenges To Singapores Education At the Teachers Day Rally last September, Prime Minister Goh Chok Tong outlined the challenges to our education system. A key imperative was National Education. Many Singaporeans, especially pupils and younger Singaporeans, knew little of our recent history. They did not know how we became an independent nation, how we triumphed against long odds, or how today’s peaceful and prosperous Singapore came about. This ignorance will hinder our effort to develop a shared sense of nationhood. We will not acquire the right instincts to bond together as one nation, or maintain the will to survive and prosper in an uncertain world. For Singapore to thrive beyond the founder generation, we must systematically transmit these instincts and attitudes to succeeding cohorts. Through National Education, we must make these instincts and attitudes part of the cultural DNA which makes us Singaporeans. The Prime Minister set up a committee, chaired by Mr Lim Siong Guan, to study how to introduce N ational Education into our education system. The Committee has worked out a plan to do so. To take the next step forward, we need the full commitment of every teacher and principal. National Education is not just a book subject. It must appeal to both heart and mind. Unless you are personally convinced of its importance, committed to the cause and have the knowledge and passion to teach National Education competently and whole-heartedly, the plan will fail. Lessons from Other Countries Singaporeans are not unique in needing National Education. Other countries take National Education as a matter of course. Japan is a tightly-knit, cohesive and group-oriented society, with a long history and a strong sense of unique identity. Yet Japanese schools start early to teach pupils Japanese culture, values, history and geography, and even the politics and economics of Japan. As pupils get older, they also learn about the cultures and histories of other countries. In so doing, they understand even better what makes them uniquely Japanese. Japanese schools go to great lengths to instill group instincts and a sense that every student is an equal member of the group. They have strict regulations on school uniforms, school bags and shoes. Students are grouped into teams called ‘hans’. Members of each han play together and eat together. They take turns to perform specific responsibilities, whether it is the daily cleaning of school premises or serving lunch. Academically stronger students are expected to help their weaker friends. Those who do not are ostracised. Students organise the school sports day themselves. Competition is based mainly on team events; there are few or no individual events. All students participate, including those with disabilities. Japanese schools do all this not because they believe that all students are the same in every respect or have identical abilities. But they want every student to be equally valued as a member of the group, recog nised for his strengths, and for what he can contribute to the group. And so it goes for Japanese society. In US schools, every child is taught the American heritage – George Washington, the Declaration of Independence, the US Constitution, the Civil War, and the Civil Rights movement. Students take part in community service. Learning to be a responsible citizen begins young. It is a deliberate inculcating of American political and social values and ideals, to ensure the next generation grows up with these ideas deeply ingrained. It is a process of indoctrination like any other, no less so because the children are brought up to cherish American values of individual liberty. And it is so successful that many Americans are completely convinced that American values are universal values of mankind.

However, tribal did not have any such plans even though the soldiers misunderstood them. The soldiers thought that the Lakota collecting arms to fight against the government and they tried to disarm the tribal. The battle of Wounded Knee happened on December 29, 1890, near Wounded Knee Creek in South Dakota, USA. A simple incident resulted in a massacre at Wounded Knee Creek. On the morning of December 29, U.S. 7th Cavalry Regiment troops tried to disarm the Lakota who fought against the American troops earlier. During the process of disarming the Lakota, a deaf tribesman was reluctant to give up his rifle which resulted in the 7th Cavalry opening firing indiscriminately from all sides, killing innocent people including men, women, and children, as well as some of their own fellow troopers. â€Å"It is believed that the accidental shot, fired while the deaf Native tried to maintain his hold on his weapon, caused others in the crowd (Native or white, there are counter claims as to which) to open fire† (The Battle Of Wounded Knee). â€Å"A single shot fueled the already charged atmosphere into a full-fledged eruption within a matter of seconds†(What Was The Battle Of Wounded Kn ee In 1890?).

There is little variation between sub communities and women are mostly confined to the home and "homework". basically, deficit theory says that some people are just stupider than others - ie they lack intelligence - and reproduction theory simply builds on this, arguing that schooling has to be organised around such manifest and unalterable differences. deficit theory reveals the fact that lower socio economic groups are systematically disadvantaged with respect to educational resources, and reproduction theory shows how these disadvantages have persisted as a result of policy failure. deficit theory reveals the fact that lower socio economic groups are systematically disadvantaged with respect to educational resources which implies the problem could be fixed by switching resources to areas of need, whereas reproduction theorists, like Murphy, insist it is not a resource, but a motivational problem, and lower socio economic groups are just not interested in more schooling! deficit theory assumes that currently "failing" kids could succeed if only they adopted the requisite - ie middle class - values, skills and motivations etc, whereas Reproduction Theory insists that since schools are set up to "reproduce" class privilege, such kids will always "fail". Goldthorpe shows that the number of "branching points" in educational decision making are critical in the reproduction of class differentials, comprehensive education, favoured by the Swedes, reduces the number of branching points. Educational differentials reflect class differences in cost benefit evaluations of educational options. The example of Sweden is significant because there the reduction of class educational differentials was accompanied by

Misconceptions occur in various areas but their detrimental effects are felt most acutely in the academic field, because it interferes with the progress that students are able in the development of cognitive skills and learning. Misconceptions that occur in the field of academic studies make it difficult for students to effectively assimilate their lessons and perform well, because these misconceptions function as a barrier that impedes the cognitive assimilation and understanding of concepts. The National Curriculum Council for Great Britain has pointed out some common student misconceptions in Algebra, such as treating letters as objects or completely ignoring their presence (www.learnquebec.ca). Misconceptions in the field of science occur mainly because of the difficulties students face in understanding everyday phenomena through abstract or symbolic representations. In biology, misconceptions occur because students are unable to grasp the concepts which they find to be too theoretical and abstract, especially in regard to concepts such as natural selection and evolution.(Burton and Dobson, 2009). According to Joan Solomon, students may also find it difficult to assimilate concepts because they may be associated with every day use, for example the word energy, and using concepts in science requires the interpretation of everyday phenomena in abstract terms, which may also involve the use of symbols to explain commonplace events(www.2ucsc.edu). In effect, there is some contextual learning that may have already taken place before a student attends classes and it becomes necessary to ensure that the student is able to learn how to learn through the use of concept

Assisted suicide should not be legalized in Canada Essay

Assisted suicide should not be legalized in Canada - Essay Example The Canadian statutes prohibit physician-aided suicide. In Canada, ever since 1972, suicide has not been a crime. However, a physician-assisted suicide is against the law. Section 241(b) of the Canadian Criminal Code stipulates that any individual who assists another person to execute suicide, and whether the suicide is successful or not is actually responsible for the offense (Prado) 80). Regulations that do not allow physician-aided suicide together with euthanasia are constitutionally aimed at protecting the Canadian people. On the other hand, there have been debates on whether the state should decriminalize it or not. The most prominent case that opposed the law was the Sue Rodriguez against the British Columbia Supreme Court. Rodriguez pleaded with the Supreme Court of Canada to allow someone assist her end her life since she was suffering from a progressive brain disease (ALS) that would eventually kill her. Therefore, Rodriguez wanted to avoid the terrible suffering by having someone aid her take her life. In the same way, on March 2012, in Quebec, the legal institution ruled that the current regulation prohibiting assisted dying is discriminatory and overboard, as well as disproportionate. This ruling was followed by an appeal by the federal government. The proponents and opponents of the legalization of assisted dying continue to hold their views. In the province of Quebec, on June 2014, the physician-assisted suicide became legal. As cited by McLellan, between 1990 and 1998, Dr. Jack Kevorkian helped in the suicides of more than 120 terminally sick individuals. Pursuing this further, the proponents of criminalization of assisted-suicide argue that the recent developments in medical technology have made it possible for people to live for years prior to their natural death. Studies have demonstrated that patients who die by means of assisted suicide were most of the times diagnosed with depression. As cited by Kirkey, there is a

Black Representation in Postbellum Era Art

Black Representation in Postbellum Era Art Heroes in art and imagery in post-bellum 19th century America Following the abolition of slavery in 1865, it took a substantial amount of time for the representation of African-American people in American art to establish itself beyond the grotesque and the caricatured. Before slavery and the plantations were outlawed due to the civil war, American representation of blacks were shown as cartoon caricatures; as generic, racial stereotypes with no individuality of their own. This is demonstrated by a number of artworks prevalent at the time. Blackness was either relegated to the sidelines of the paintings, sculpture and engravings, or else excluded completely from the image. And although the outlawing of slavery was done in order to generate equality and liberty across the United States, racism was still prevalent, and it would also take some time before the actual identity of blackness in the United States managed to transcend that of an oppressed, racial stereotype, and began to take on and represent a history and a culture of its own, instead of merely providing the negative for the representation of whiteness. A great many critics argue that this breakthrough was made ironically by a sculpture made and funded by white people, in the Shaws Memorial by Augustus Saint-Gaudens. Despite Saint-Gaudens obvious inclinations towards racial stereotyping in words (his memoirs justify this statement), thanks to a number of coincidences, his artistic credibility, and the amount of time he was given to produce this sculpture, he managed to represent blackness not as caricatured, but as a disparate but unified whole. But some critics of the Shaw Memorial still uphold the belief that it is inherently racist. In the following essay, I will look briefly at the history of black representation in the art of post-bellum America, than engage in a closer analysis of the Shaw Memorial, in order to see exactly what is being represented and how. Monumental sculpture in particular had a great history in providing people with allusions to the real, held as less of an illusion than the representations made in other arts, such as painting. The representation of Apollo in the famous sculpture had provided people with a benchmark for human aesthetic beauty for thousands of years, and sculpture seemed conducive to the production and the replication of this ideal human form. This has serious implications for the evolution of how Black American slaves in postbellum America were represented. Kirk Savage suggests that: â€Å"Sculptures relation to the human body had always been more direct and intimate than paintings: the sculptors main task was not to create illusions on a flat surface but to reproduce three-dimensional bodies in real space.†[1] Additionally, because of the importance by which public sculpture was held at the time, as a monument dedicated to, rather than imposed upon the community, the development of a realisti c representation of the African American body in the art of the time is not to be underestimated. Savage goes on to say: â€Å"The sculpture of antiquity thus became an authenticating document of a normative white body, a race of white men.†[2] The fair representation of blackness in sculpture was therefore central to the cause of representing blackness as equal in America. However, it would still be some time before the representation of the hero would be anything but white. This white hero occurred on both sides of the slavery divide, as those from the South would paint a picture of the generous, selfless plantation owner, whereas those from the North would paint an equally white picture of figures fighting for the liberty of black slaves. From the Journal of Popular Culture: â€Å"In the postbellum reminiscences, a slaveholders chivalric spirit was manifested through feats of selfless generosity.†[3] Also, representations of the South didnt differ: â€Å"refusing to concede an exclusive grant of heroic title to the friends and relatives of slaveholders, those who had gloried in the 1865 Union victory demanded an equal chance to create their own champions of popular culture. In the manner of their southern counterparts, they sought to rescue from oblivion the true history of an unpretending, liberty-loving and Christian people.†[4] So, despite the liberal intentions of the North, their representations of blacks were still stuck in a post-plantation world: the blacks were to be represented as symbols of otherness – of cartoon caricatures, and only there to represent their emancipation by the heroes of white culture that had freed them. Sculpture is also a particularly difficult medium with which to represent skin colour, because the tone of the skin cannot directly be represented: â€Å"Since sculpture was understood then to be monochromatic, sculptors could not represent skin color directly.†[5] How then, was skin colour represented in the medium? In John Rogers Slave Auction (1859) blackness is represented as a series of facial features. He is identified by his position in front of the stand, but also by his curly hair and his full lips. By representing the Negro as defiant, with arms crossed, â€Å"the work attracted the attention of some local abolitionist newspapers and acquired a limited public reputation.†[6] However, the problem was still unresolved: of how to represent an image of blacks in sculpture that wasnt patronising, denigrating or clichà ©d, which still represented the identity of blackness in what was essentially a monochromatic medium. Savage continues: â€Å"artists after the Civ il War faced the great challenge of representing a society recently emancipated from slavery, that brought to the task various assumptions and images that had been deeply ingrained by the system of slavery and by the long campaign to abolish it.†[7] Blackness was, in effect, so heavily linking to its white-established origins of slavery, that it was a seemingly impossible task to represent it in any other way, never mind to represent blackness in a heroic light. Due to the uniform way in which blackness was represented, it was impossible to reconcile the image of a black hero with this symbol of the homogenised masses, either there to be emancipated, or else enslaved by the dominant white society that controlled politics, society and the power mechanisms of postbellum America. If blacks were represented at all, they would be seen as stereotypes of a series of white-defined black assumptions concerning black facial imagery. Fryd suggests that: â€Å"It is possible that because of the continuous threat of disunion from slavery, both northerners and southerners felt that they needed to banish blacks from the artworks.†[8] Because of the knotty subject matter concerning black autonomy, it took a while before blacks could be represented as heroic even in the slightest. This representation is epitomised by the painting Cornwallis Sues for Cessation of Hostilities under the Flag of Truce (1857). In it, a black man is seen hiding in the far r ight corner of the painting, his face obscured by a hat, wedged behind two white officials. The dark background, coupled with his dark clothing and dark face disguises his presence in the picture. He is also seen with an earring, curly black hair and thick lips; a typically stereotypical representation of blackness. Fryd suggests that: â€Å"The figure is barely visible given the prominence of the three central figures, and the importance of Washington in this ceremonial painting celebrating the generals astute ploy to force the British surrender.†[9] So, the image of the hero is used here to grab the attention and, while the other white people rally round and bask in the nobility and the light of Washington, the black man is confined to the far right of the page, looking somewhat sheepish, and ostracised from the composition by his colour and his position in the painting. So, postbellum art, in the immediate aftermath of the Civil War, was still primarily concerned with representing blackness as something passive; something to which things had to be done, whether this thing was emancipation or else slavery. The development of Shaws Memorial, and the numerous copies that Saint-Gaudens later made in an attempt to perfect his masterpiece, in many ways marks a turning point in the development of an autonomous series of black characters, noted for their individuality, as well as their allegiance to a particular racial and socio-economic group. However, the presence of Shaw, and the titling of the monument (the Shaw Memorial dictates that Shaw is the most important character), as well as his composition, leads us into thinking about the following question: Is the Shaw Memorial a sophisticated representation of blackness in post-bellum art, or is it simply a similar propagation of the racist values of whiteness held previously? Of course, it is impossible to divorce the Shaw Memorial entirely from perceiving the African Americans as an oppressed group because, historically, they were. Savage argues that: â€Å"The Shaw Memorial introduced the element of black recognition into the more conventional worship of white heroism.†[10] Indeed, the depiction of heroism is intrinsic to the understanding of this piece: although the African-Americans are seen as a group of people, they are also, thanks to the meticulous and painstaking sculptural perfectionism of Saint-Gaudens, seen as individuals, as Saint-Gaudens used models found on the streets of New York to develop a realistic depiction of a great variety of black people. However, Saint-Gaudens choice of developing and individuating the black soldiers at the bottom of the piece was also due to economics and artistic integrity, more than actually consciously trying to represent blackness: he says in his memoirs that â€Å"through my extreme interest in it and its opportunity, [I] incre ased the conception until the rider grew almost to a statue in the ground and the Negroes assumed far more importance than I had originally intended.†[11] The prejudices of the sculptor was also clear, and releases all manner of underlying problems with the authenticity behind how blackness is represented in the piece: â€Å"It is fascinating that this exploration of black diversity came from the hands of a white man who shared the common racial prejudices of the white elite. In his memoirs, Saint-Gaudens writes quite disparagingly about his black models, who are brought into the story merely as comic relief. They come odd as foolish, deceptive, and superstitious, though Saint-Gaudens is careful to say that he likes them for their imaginative, though simple, minds.†[12] Indeed, Saint-Gaudens textual representation of Negroes was as fraught in stereotype as the average member of the white elite, but somehow, due to the nature of his artistic perfectionism, as well as the conditions for producing a statue with the singular intention of promoting racial awareness, he managed to transcend these barriers of personal prejudice and made something that helps not simply to represent blackness as a patronising simulacrum of white values, but represents blacks as they are, in a way that is not patronising or denigrating. It is also fair to assume that the economic conditions of the artwork surpassed the actual intentions of the master sculptor, which was, at least according to early drafts, simply to represent Shaw as a great leader, without any direct or detailed representation of blackness. But, as time passed, Saint-Gaudens became more interested in representing blackness: â€Å"Deciding instead to represent the soldiers as distinct individuals, he became fascinated with the material reality of their own diversity. He wanted the defy military uniformity, on the one hand, and racial caricature on the other; both in their own ways were strategies of standardization. For the sculptor, blackness did not become a leveling trait but a field in which to create a rich interplay of internal differences.†[13] It was this rich interplay that served to develop the heroic quality of blackness in art in 19th century American art. As the statue stands, the individuation of blacks serves to treat them as heroes, albeit heroes of a group, rather than a singular hero held in noble esteem. The white officer, however, is still glorified over and above the black soldiers that march underneath. Despite his lowly position in the ranks of the army, he is glorified simply because of his position leading the â€Å"despised race†. This is a problematic issue: â€Å"racial difference [of making Shaw representative of a group of black soldiers] made this idea of representation problematic at best. Could Shaw, a high-born white man, represent a regiment of black troops?†[14] Thus, the position of Shaw as hero, towering above the distinct blacks, renders the usage of the standard equestrian imagery slightly uncomfortable. However, Saint-Gaudens also uses rhythm in a sense to convey that Shaw does not dominate the black soldiers, but leads them instead. Shaw holds a sword that is angled in rhythm to the marching soldiers. The horse is strained, but Shaw holds it back, and the whole image is composed to generate both diversity, and homogeneity. In the representation of blackness, for instance: â€Å"we see the drummer boy juxtaposed with the sergeant behind him, the youngest member of the group with the oldest, smooth skin with beard, short stature with height; but if we read into depth, other more subtle contrasts emerge too, of facial hair, cheekbone, nose and eye shape. [] In this way the overall impression of uniformity – of identically clad soldiers marching perfectly in step, rhyming each others body movements – is changed and enriched by a kind of contrapuntal rhythm of diversity.†[15] In postbellum art, the concern was primarily with establishing the autonomous and individuated identity of a previously oppressed group of people, while maintaining the traditional structures of the depiction of the hero, with respective notions of beauty, leadership and nobility, that proved to be a problematic mix to endeavour to achieve. Thus, the South turned to the plantation owners for their heroes – the chivalric and generous heroes, displaying their generosity towards the blacks, and treating their assumed inferiority with compassion and grace. Similarly, in the North, the contemporary hero of postbellum art was the white emancipator of the blacks, fighting for the freedom of this oppressed race of people. The result was that the hero didnt particularly change race, and that common perceptions of human aesthetic beauty, a notion that went back to Greek times, remained largely the same. However, despite taking on the traditional format of the equestrian hero statue, the Shaw Memorial assists in combining these two glaringly contrasting issues, by depicting both the individuality and the homogeneity of the black cause, as well as preserving the image of the white hero – Saint-Gaudens does this using subtle techniques of composition, by combining rhythm, and by representing a great swathe of meticulously studied, and strikingly different black faces, that ultimately combine to produce â€Å"interplay† in racial profiling. Savage comments that: â€Å"In this monument Saint-Gaudens was able to elevate the white hero without demoting the black troops.†[16] and it is testament to his genius that, despite his personal prejudices, he managed to fully articulate and display through the medium of monumental art, the autonomy, yet the solidarity of an entire race of people, within the context of the traditional white hero monument.

Thomas Young :: biographies bio physics physicist

Thomas Young (1773-1829) Thomas Young was a brilliant man throughout his life. At a young age of fourteen, he was familiar with Latin, Greek, French, Italian, Hebrew, Arabic, and Persian. He was so educated in a variety of areas that his peers called him Phenomena Young. This Englishman found interest in languages, medicine, nature, and light. He did his studies in London, Edinburgh, and Gà ¶ttingen, and practiced medicine in London. With his strong interest in sense perception, he was able to make many realizations and discoveries about the eye. For example, he was the first to realize the eye focuses by changing the shape of the lens, he discovered the cause of astigmatism, and he and Helmoltz initiated the three color theory of perception. In 1801, regardless of the uncertainty from other scientists, his double-slit experiment established that light was a wave motion, making his famous. Over the years, he gained new interests. He started studying Egyptology, and while he was one Napoleon’s expedit ions he started studying the texts of Rosetta Stone. This in time helped to decipher the ancient Egyptian hieroglyphic writing. Some other interests that Young acquired over the years, leading him to more discoveries are surface tension, elasticity and energy. He even worked as a professor at schools, including the Royal Institution and Cambridge University. Thomas Young was a smart, well educated English physician and physicist. His love for his work and interests allowed him to make discoveries that help us to this day, and to be remembered and acknowledged as â€Å"†¦a man alike eminent in almost every department of human learning.† Lifelong Accomplishments 1773 -Thomas Young is born 1792 -Young decided on a career in medicine. 1793 -Presented a paper before the Royal Society in which he attributed the accommodation of the eye to its muscular structure 1794 -Elected to membership of the Royal Society -After completing his medical studies at Edinburgh and Gà ¶ttingen, he returned to London to practice but continued his scholarly studies at Emmanuel College, Cambridge -His uncle died, making him financially independent, allowing him to pursue his real interests 1798 -Some investigations on sound and light formed the starting point for his theory of interference 1799 -Began his medical practice in London -While attending medical school, he discovered how the lens of the human eye changes shape to focus on objects at different distances 1800 -Published his experiments on Sound and Light in the Philosophical Transactions of the Royal Society 1801 -Discovered the cause of astigmatism -Young and Helmholtz initiated the three color theory of perception.

America’s Culture of Sex :: Sex Media Television TV

America’s Culture of Sex Sex in today’s world can be seen anywhere. It is on billboards, radio stations, personal books, school books, magazines, peers, movies, songs, and the most famous is televisions. Commercials use seductive images, sounds, and music grabbing the attention of the audience. Movies and television are proof of the sickness of sexual addiction in society. This disease spreads across the country, infecting the way people think and live their lives. Ultimately it is destroying society and what America holds to be morally correct. Two such sources of writing, â€Å"Sic Transit Gloria†¦Glory Fades† and Countering the Culture of Sex, give examples of what effect culture play in the way of living. Today’s culture pumps out messages of sexual immorality and the idea of sexual relations outside of marriage are fine. Sexual immorality can destroy families and create dysfunction in the sacred vows of marriage. â€Å"Sic Transit Gloria†¦.Glory Fades† is a song by Brand New. It tells a story of a man who is very inexperienced sexually, and a girl who knows her sexual skills like the back of her hand. The young man wants only to hold this girl and love her. Instead he is pressured into sex with her, even though he really never wanted. Sex is what she wants and he knows it would make her happy by giving into her. He feels horrible while this happens, but he will not stop because he wants to impress her. Countering the Culture of Sex is an article by Ellen Goodman dealing with the entertainment industry’s plague upon society. With sex rooted deep in children’s minds it creates this idea of what life revolves around. Digging deeper, Goodman brings up the point of why one never sees the consequences of sex. If the media were to show the consequences of people’s actions, the industry could create a sense of fear into the public. The big picture between these two texts says sex is a problem in society.

The Frontier in American History

There are quite several sharp notions in The Frontier in American History by Frederick Jackson Turner, and all of these notions very well contribute to the revelation that with diversity comes the great possibility of acquiring an identity independent as it is from everything else outside.Although much of what is written in the collected essays verifies the idea that the creation of a government of the people surpasses that which is merely imitated, the role of the external elements can be argued as indispensable elements in the establishment of an identity.   One of the central themes in The Frontier in American History is the idea of the formation of the government that is distinctive and proper to the Americans.The author, Frederick Jackson Turner’s viewpoint in the book evidently shows his aim towards rendering a piece which will devote on tracing the history of America as well as with the nature of civilization.It has been noted that Turner was one of the ambitious demo cratic leader with the bias on lurking deep on the â€Å"flaws† of those who are in office which furthers his conviction on self-reliance and the turmoil revolving around political idiosyncrasy.The author was a piece of hopeful being.   Further, another major limitation of Turner's thesis is that it does not adequately recognize the extent to which frontier societies are shaped by the economic and political systems of the states in which they are located or to which they are most closely linked.It is not merely expansion into a wilderness that explains the character of a frontier society, but rather expansion within a particular social, economic and political context. In the slave states, for example, westward expansion occurred within an economic and legal context that transplanted the slave system and the values that went with it into new areas.Written in the year 1920, several collaborations on the critique made in the light of The Frontier serves a moral vision, as pres ented in Chicago during the World’s Columbian Exposition and has even garnered his works Pulitzer Prize awards a year after he died[1].This Wisconsin legend in history and literature has made a large impact on the society that his works were often placed in the table of deliberation as either that which is intellectually beneficial in the astounding arena of history or that which defeats the sagacity of being a historian.The main fact that he held his theory on high hopes in building a feasible force in the economic, social and political discussion in America, it is undeniable that majority of historians having the attempt to fully bring up the marvel of The Frontier is admirably an epic as his works were given worth and space in encyclopedias as well as in classroom deliberations.Turner’s argument is grounded on the premise that a government that is shaped according to other nations or that which resembles or at least partly incorporates external elements from foreign nations will not be suitable for the people and for the entire nation. It can be observed thatTurner firmly adheres to the principle of having an identity that is solidly based on what is natural to the people and to the rest of the country. What is natural supersedes those that are artificial—what is essentially natural to America is ‘diversity’ in the truest sense of the word[2].Apparently, Turner makes it a point to bridge the issue with diversity to that of having a strong government structured according to the innate qualities of the American people. However, it fails to consider the fact that diversity also grants the substantial possibility of not actually unifying all the corners of the country into a single and identifiable sphere[3].What Turner does is to transcend this ‘diversity’ and patch all the different—albeit intrinsic—‘American’ elements into a unified concept that virtually quells, at least in theory, th e force of other external factors. He does this at least in the sense of proposing an ‘ideological’ battle, one that treats ideas far superior than brute or physical force.Although Turner argues that bloodshed is inevitable, he also suggests that the ideas of man will have to take the core of the movement towards the establishment of an independent and unique government and that these ideas should come from the American people themselves and not from anybody else.[1] Schultz, S.

Calorimetry and Hess’s Law Essay

Elemental magnesium is one of the principal components of flares used to illuminate nighttime activities, or to aid in signaling one’s location to aircraft and ships. Your instructor may ignite a strip of magnesium ribbon to demonstrate the combustion of magnesium in air. It will be evident that a great deal of light energy is released from this reaction. A direct method for measuring the heat produced by this reaction would be difficult, so we shall resort to an indirect method in this experiment as discussed below. Some chemical reactions (including the one above) are associated with the evolution of thermal energy and are called exothermic reactions. When there is absorption of energy in a chemical reaction, the process is called endothermic. The magnitude of the energy change is determined by the particular reaction as well as the amount of product(s) formed. The thermal energy transferred in a balanced chemical reaction carried out at constant pressure is called the enthalpy of reaction (or heat of reaction) and is  given the symbol ΔHrxn. ΔHrxn is often expressed in units of kJ/mole where mole refers to the amount of a reactant or a product involved in the reaction. In general, the reactant or product must be specified. In this experiment, you will measure the enthalpy changes of several exothermic reactions utilizing a simple calorimeter. This calorimeter consists of an insulated vessel (a Styrofoam cup), a thermometer, and a lid (which is loose fitting to allow the pressure to remain constant. The energy given off by any reaction carried out in the calorimeter is absorbed by both the calorimeter and the solvent (water). This causes an increase in the temperature of the calorimeter and solvent that can be me asured by a thermometer. The heat that is absorbed by the calorimeter and solvent is calculated from the equation: qcal = C â‹… ΔT (1) where C is the heat capacity of the calorimeter and solvent, and ΔT is the change in temperature of the water (the solvent) in the calorimeter. Heat capacity is defined as the amount of energy required to raise the temperature of an object by 1  °C. In this experiment, the vessel and the amount of solvent remain constant, so C is a constant. Enthalpy is an extensive quantity, so the amount of heat generated by the reaction is given by the expression: qrxn = n â‹… ΔH (2)  where n is the number of moles of a specific reactant or product and ΔH is the enthalpy change of the reaction in kJ/mol. Since the energy of the universe is conserved, the total energy change of the system (the reaction) and surroundings (calorimeter and solvent) is equal to zero. These relationships can be combined as shown in equation (3). qsystem + qsurroundings = qreaction + qcalorimeter = n⋅ΔH + C⋅ΔT = 0 (3) This equation can be rearranged to determine either C or ΔH as shown in equations (4) and (5). C = − n⋅ΔH/ΔT (4) ΔH = − C⋅ΔT/n (5) For exothermic reactions, ΔH < 0 and ΔT > 0. The main experimental problem in any calorimetric measurement is obtaining an  accurate value of ΔT. The initial temperature, Ti, of the reactants can be determined directly using a thermometer. However, it is difficult to obtain a precise value for the final temperature, Tf (the instantaneous temperature when the reactants are mixed together and react), because (1) reactions do not occur instantaneously, and (2) calorimeters are not perfectly insulating, but actually allow some heat energy to slowly enter or escape from the calorimeter over time. This occurs both during the reaction and after its completion. If an exothermic reaction occurs in a hypothetical calorimeter that is perfectly insulated, all of the heat produced by the reaction will remain in the calorimeter, resulting in a constant final temperature. This would yield the same ΔT whether or not the reaction is instantaneous. Now consider a hypothetical exothermic reaction that occurs instantaneously, but in a realistic calorimeter that is not perfectly insulated. In this case, the temperature of the calorimeter would diminish over time due to the gradual escape of heat energy to the surroundings. ï€  The â€Å"final† temperature to be used in determining ΔT in this case is actually the maximum temperature reached immediately after reaction occurs, since this temperature change is due exclusively to the heat produced in the reaction, and no escaping of heat to the surroundings has occurred yet. For real calorimeter experiments, reactions neither occur instantaneously nor are calorimeters perfectly insulated. Thus, during an exothermic reaction the temperature of the calorimeter increases initially, but never has a chance to reach the correct maximum â€Å"final† temperature since heat is escaping to the surroundings even while the reaction is proceeding toward completion. A correction for this heat exchange is made by an extrapolation process using the temperature vs. time curve (see Figure 1). First, a plot of the temperature readings as a function of time for the reaction is generated. By extrapolating only the linear portion of the curve (e.g., the points including and after the maximum temperature) back to zero time (the time when the reactants were mixed in the calorimeter), Tf is obtained. The Tf value determined in this manner will be the temperature that the calorimeter and the solvent would have reached, had the reaction occurred instantaneously and with no heat exchange to the room. This value should be used for the calculation of change in temperature, ΔT. Consult with your TA for specific instructions for extrapolation using Microsoft Excel. A. Determination of the Enthalpy of Combustion of Mg Using Hess’s Law The calorimeter will be used to determine the enthalpy of combustion of magnesium by application of Hess’s law. Consider the following reactions: (a) H2(g) +  ½ O2 (g) → H2O (l) ΔHa = − 285.84 kJ/mole (b) Mg(s) + 2 H+ (aq) → Mg2+ (aq) + H2 (g) ΔHb (c) Mg2+ (aq) + H2O (l) → MgO (s) + 2 H+ (aq) ΔHc By adding equations (a), (b), and (c) we obtain (d) Mg (s) +  ½ O2 (g) → MgO (s) ΔHrxn = ΔHa + ΔHb + ΔHc which represents the combustion of Mg(s). Reaction (a) represents the formation of liquid water from its constituent elements. The enthalpy change for this reaction, symbolized ΔHa above, is the standard heat of formation of liquid water (or ΔHf (H2O)) and is a known quantity. ΔHb and ΔHc will be determined experimentally by measuring the temperature rise when known masses of magnesium metal and magnesium oxide, respectively, are added to hydrochloric acid. Reaction (c) as written is an endothermic reaction. Since it is easier to perform the reverse (exothermic) reaction, the data you collect will be of opposite sign to that needed for the Hess’s law calculation for reaction (d). When data from your analysis is correctly combined with that for the known reaction (a), the enthalpy of combustion of magnesium metal can be obtained. PROCEDURE: Note: Handle the Styrofoam cups gently. They will be used by other lab sections! A. Determination of the Enthalpy of Combustion of Magnesium Reaction of Magnesium Metal and Hydrochloric Acid 1. Using the graduated cylinder, add 50.0 mL of 1.0 M HCl to the empty calorimeter. Wait for a few minutes to allow the set-up to reach thermal  equilibrium. 2. While waiting, determine the mass of a sample of magnesium ribbon (about 0.15 g) on the analytical balance, and then wrap it with a piece of copper wire. The copper will not react in the solution; its purpose is to prevent the magnesium from floating to the surface during the reaction. Do not wrap the magnesium too tightly or it will not react quickly enough with the HCl solution. Do not wrap the magnesium too loosely since it may escape the copper â€Å"cage† and float. 3. Using LoggerPro, start a run of 500 seconds with the temperature probe in the 1.0 M HCl in the calorimeter (with lid). 4. The magnesium/copper bundle is added to the HCl solution. Replace the lid with the thermometer in place, and begin swirling to mix. Be sure to support the temperature probe. Continue swirling and collecting data and record about 300 seconds or until the temperature starts decreasing. This will provide the linear part of the curve, and are the most important points for the extrapolation procedure. 5. When data collection is completed, rinse the calorimeter and thermometer with distilled water and dry as completely as possible. Place the piece of copper in the container labeled â€Å"copper waste.† B. Reaction of Magnesium Oxide and Hydrochloric Acid 1. Place 50.0 mL of 1.0 M HCl into a clean graduated cylinder. 2. On a top-loading balance, transfer approximately 0.7 to 0.8 g of MgO to a clean weighing boat (no need to record this mass). Next, determine the mass of the MgO and the weighing boat on the analytical balance and record the data. Transfer the MgO to the dry calorimeter. 3. On the analytical balance, record the mass of the â€Å"empty† weighing boat after the transfer and calculate the mass of MgO actually transferred to the calorimeter. 4. Record the initial temperature (Ti) of the 1.0 M HCl solution in the graduated cylinder. 5. Note the time (time = zero) and add the 50.0 mL of 1.0 M HCl to the calorimeter containing the MgO. 7-8 points after the temperature maximum. In this reaction all the MgO should react since HCl is used in excess. However, if the solid MgO is allowed to sit on the bottom or sides of the cup it will not dissolve and hence it will not react. Make sure the solution is mixed constantly but gently. (NOTE: Before discarding this solution, check to see that all of the MgO has reacted. If solid MgO remains, the results from this portion of the experiment are not accurate. If any solid is present, this portion of the experiment must be repeated.)  6. When data collection is completed, rinse the calorimeter and thermometer with distilled water and dry as completely as possible.
