A Dolls House :: A Dolls House Essays

A Doll's House    The author, Henrik Ibsen, who wrote other social commentary plays (like Ghosts, Enemy Of The People, and Pillars Of Society), made a departure in this plays ending by having the protagonist run away rather than staying to set an example and continuing to struggle for the better along side others. This scenario creates a sad, troubling and for Nora unjustified ending as she, the protagonist in A Doll's House, leaves Torvold, her husband. She destroys any hope that married couples can reconcile differences and learn to change and grow with one another. Nora's exit is a self- destructive assertion of her childlike and romantic view of life, that somehow, someway, things will work out even though there is no plan on her part as to how.   By leaving, Nora, with no expectation of a support system, provides no significant transforming effect upon her family's lives and views.   Nora has an egotistical and self-centered idea about life and this is further exposed when she dec ides to abandon her family. Everyone must compromise at some time in their lives. This leads to cooperation in family and in society and is the essence of survival and growth. Nora's need to be in control and her role playing manipulations, makes her an equally guilty party in the promotion and continuation of a stilted and stifling middle class lifestyle that was Norway in the mid 1800's.    The title sets up the metaphor - this is truly a doll's house. But in this case the main    characters are not only the dolls themselves but the doll master and mistress each vying for    power and control. This is a central conflict of the play. Torvold may be the master in the eyes    of society and adopt a conventionally controlling tone but Nora has the real control by her    power of manipulation. Nora is the one who is getting her own way, eating macaroons and    spending money (and getting more) as her wishes prompt. Appearing confident and happy    she shows no sign of dissatisfaction with the role. She gives the porter who brought    the Christmas tree an over-generous tip despite a lack of money

The New Deal Coursework

The New Deal was set up by Franklin D. Roosevelt when he became president of the United States of America in March 1933. Roosevelt introduced the New Deal to stabilise the USA, focusing on his aims that he put forward in his inaugural speech. Roosevelt made his inaugural speech in March 1933, declaring his main aims that he planned to achieve during his time as President. During his speech Roosevelt said: â€Å"The only thing we have to fear is fear itself.† He said this because he wanted to assure the American citizens that he could reform the current depression in the USA and make sure no such crisis could happen again in the future. He wanted to regain the American people's confidence in that the problems caused by the Great Depression should no longer be feared because he had a plan to resolve the bad effect of the depression on his country. Roosevelt said that he aimed to make better use of natural resources, and to lower unemployment figures by providing jobs for thousands of people. He also said that he was aiming for the protection of people's savings and property, a redistribution of the land for those less privileged and to provide aid to the ill, elderly and unemployed. Roosevelt was granted one hundred days of broad executive power so that he could achieve his aims by passing laws quickly without having to put them through the government. With this power Roosevelt set up the â€Å"Alphabet Laws† that were combined to form the New Deal. The different laws he passed allowed him to achieve the aims that he had proposed in his inaugural speech. To accomplish his first aim of restoring confidence in the American citizens, Roosevelt came up with the idea of the â€Å"fire side chat†. The fire side chat was a radio show that Roosevelt would speak on every night, in a bid to convince Americans that he would make sure that America recovered fully from the Great Depression. Because the fire side chat was a daily occurrence, it could been seen as a form of propaganda but the radio shows did in fact give confidence to Americans in the way that they he made people believe that he would keep the promises he made to help America recover. One of the first of the Alphabet Laws that Roosevelt set up was The Emergency Banking Act. The Emergency Banking act was, to all intents and purposes, a four-day bank holiday; when all the banks were declared financially secure they were allowed to be reopened but those which were not were closed. Roosevelt set this act up to restore the Americans' faith in the dollar and to systematize America's economic situation. The Emergency Banking Act abolished Americans fears that their savings were not secure and let them put their trust back into the banks where they kept their money. Another program that Roosevelt set up was the Federal Emergency Relief Administration which was established to provide benefits for the unemployed. The basis of the program was that the government would give a dollar for every three dollars that the state spent; this was supposed to give people confidence that the unemployed would be given enough money to live on until a job opportunity came about. The fact that the Government was showing interest in the well-being of American people, made people believe even further that it was a strong, caring government system that took into account minorities and those in need. The Federal Emergency Relief Administration was later changed to the Civil Works Administration which was a project set up with five hundred million dollars backing from the Government, which was spent on public work schemes. It gave hundreds of people jobs all across America on developments such as road works and building important public buildings such as airports and sc hools. The Labour Relations act was brought about to give employees and workers across America the reassurance that they had worker's rights and the freedom to back themselves against unfair dismissal by their employer. The Home Owners Loan Cooperation was set up to give Americans back the confidence that they were safe from being evicted from their own homes. It allowed people to take out loans so that they could pay rent until they came up with a better source of income. As well as the Civil Works Administration as a factor in achieving his aims of lowering unemployment figures, Roosevelt also set up the National Recovery Administration, the Works Progress Administration, and the Public Works Administration; all of which were work schemes that provided jobs for many people in all aspects of society from arts to agriculture. Other aims of Roosevelt were the redistribution of land and better uses of natural resources. Roosevelt set up The Civilian Conservation Corps (CCC), the Agricultural Adjustments Act and The Tennessee Valley Authority (TVA). The Civilian Conservation Corps was set up to protect the environment in many areas of the USA. As well as observations on plants and wildlife such as tree-planting and beekeeping, the CCC also built many trails and buildings in state and national parks and installed fences, and power and telephone lines. The Agricultural Adjustments Act aimed to prevent farmers from being evicted from their homes by introducing new crops to farming areas. The government would also buy a cow from a family farm and then have the meat sent back to family tinned, ready to eat. The TVA was set up in order to provide economic development in the Tennessee Valley, where many people were affected greatly by the Great Depression. It concentrated on building dams to prevent flooding and to regain land around the Tennessee River and also on electricity generation and the manufacturing of fertilizer as a source of income. Roosevelt also set up other organisations to tackle other problems such as The Social Security Act that gave aid to the ill, elderly and unemployed; and the National recovery Administration that ensured working conditions were acceptable for everyone and to abolish over working and child labour. In conclusion, Roosevelt covered all of his aims mentioned in his inaugural speech using his power to pass the Alphabet Laws in order to keep his promises that he made to the people of America. The features of the New Deal came together to successfully meet Roosevelt's initial aims as President, as he made a benefit of the environmental state of the USA by using natural resources to boost the economy and provide employment for many people, effectively killing two birds with one stone.

Critical Reflection

Reflection is one of the most important parts of any forms of learning, and is a great tool to be used to allow for greater learning. Reflection whether being a student at primary school, a university student or a member of the workforce has an effect on constructing knowledge about a person and the world around them. It is a vital part of any learning experience and will form the backbone in the transformation from study to application in a field. Reflection can be defined as ‘taking a look back’ on experiences in most contexts, and looking back at the experience analysing and learning from it so therefore ‘constructing the knowledge’ and making the person more knowledgeable and informed. Critical Reflection is â€Å"the process of analysing, reconsidering and questioning experiences within a broad context of issues (e. g. , issues related to social justice, curriculum development, learning theories, politics, culture, or use of technology). [(Wertenbroch & Nabeth, 2000)] People learn by engaging in experiences that allow them utilise their senses and interact with a subject matter. In addition to this interaction, reflection allows for one to link a recent experience with an interrelated mental experience which allows for the development of ‘higher order thinking skills’. [Dewey (1933)] Many philosophers consider Dewey the contemporary inventor of reflection, as most of his ideas stem f rom those of many famous philosophers from the likes of Aristotle, Confucius and Plato.  Read also Critical appreciation of the poem â€Å"Old Ladies’ Home†. Critical Reflection In an article by Jack Mezirow (‘How Critical Reflection triggers Transformative Learning’) he states that â€Å"Critical reflection involves a critique of the presuppositions on which our beliefs have been built. Learning may be defined as ‘the process of making a new or revised interpretation of the meaning of an experience, which guides subsequent understanding, appreciation and action’. He implies by this statement that not just having an experience will somebody just learn from that but also reflecting on the experience and appreciating and understanding the experience in order to reap the full benefits of learning it. (Murray, Kujundzic, 2005) define four activities that are central to critical reflection. These are oâ€Å"Assumption analysis† – This is step number one and involves a person to think in such a way that it challenges how they perceive certain cultural and social values and practices in order to see here impact on their daily lives oâ€Å"Contextual awareness† – Which highlights the social and personal significance of historic and cultural contexts. oâ€Å"Imaginative speculation† – Thinking of other ways to go about usual practices to challenge the current ways of knowledge. oâ€Å"Reflective scepticism† – The interaction of all of the three above mentioned activities, and the ability to think about the subject at hand in order to determine an action or viability of a matter.

Include the following printouts: A Gantt chart. A network diagram highlighting the critical path. A schedule table reporting. ES, LS, EF, LF, and slack for each activity. Hint: the project should be completed in 530 days. Remember: Save your file for future exercises! Remember the old saying, A project plan is not a schedule until resources are committed. This exercise illustrates this subtle, but very important, difference. Part A Using your files from Part 2 input resources and their costs if you have not already done so. All information is found in Tables A2. 7 and A2. 8. Prepare a memo that addresses the following questions: 1. Which if any of the resources are overallocated? 2. Assume that the project is time constrained and try to resolve any overallocation problems by leveling within slack. What happens? 3. What is the impact of leveling within slack on the sensitivity of the network? Include a Gantt chart with the schedule table after leveling within slack. 4. Assume the project is resource constrained and resolve any overallocation problems by leveling outside of slack. What happens? What are the managerial implications? 5. What options are available at this point in time? Include a Gantt chart with the schedule table after leveling outside of slack. Note: No splitting of activities is allowed. Note: No partial assignments (i. e. , 50 percent). All resources must be assigned 100 percent. When you show the resource-constrained network to top management, they are visibly shaken. After some explanation and negotiation they make the following compromise with you: The project must be completed no later than February 2, 2012 (530 days). You may assign two additional development teams. TABLE A2. 8 Organization Name Design Development Documentation Assembly/test Purchasing Group RD (2 teamsl RD (2 teams) RD (1 team) RD (1 team) Procurement (1 team) Cost ($/hr) $100 Resources 70 60 70 40 If this does not suffice, you may hire other development t eams from the outside. Hire as few external teams as possible because they cost $50 more per hour than your inside development people. Internal Development Add as many development units (teams) as needed to stay within the 530 days. If you need more than the two units, examine all possibilities. Select the cheapest possibilities! Change as few activities as possible. It is recommended you keep work packages which require cooperation of several organizational units inside your company. You decide how best to do this. Hint: Undo leveling prior to adding new resources. Once you have obtained a schedule that meets the time and resource constraints, prepare a memo that addresses the following questions: I. What changes did you make and why? 2. How long will the project take? 3. How did these changes affect the sensitivity of the network? Based on the file created at the end of Part 3, prepare a memo that addresses the following questions: I. How much will the project cost? 2. What does the cash flow statement tell you about how costs are distributed over the lifespan of the project? Include a monthly cash flow and a cost table for the project. Once you are confident that you have the final schedule, save the file as a baseline. Hint: Save a backup file just in case without baseline! Prepare status reports for each of the first four quarters of the project given the information provided here. This requires saving your resource schedule as a baseline and inserting the appropriate status report date in the program. Assume that no work has been completed on the day of the status report. Your status report should include a table containing the pv, EV, AC, BAC, EAC, Sv, Cv, and CPI for each activity and the whole project. The report should also address the following questions: I. How is the project progressing in terms of cost and schedule? 2. What activities have gone well? What activities have not gone well? 3. What do the pcm and PCIC indicate in terms of how much of the project has been accomplished to date? 4. What is the forecasted cost at completion (EACf)? What is the predicted VACf? 5. Report and interpret the TCPI for the project at this point in time. 6. What is the estimated date of completion? 7.

Free Essays on Coconut Grove Fire

The headline of the Boston Globe said it best, â€Å"Nightclub Burns, Hundreds Dead!† The worst nightclub fire disaster in history occurred more than 60 years before the Station Nightclub fire in Rhode Island. On 28 November 1942, the Coconut Grove Nightclub in Boston burned to the ground, killing 492 and injuring 166. It is believed that the fire started in the basement â€Å"Melody Lounge† section of the club, when 16-year old bus boy, Stanley Tomaszewski, lit a match in order to replace a light bulb. A fire started, fueled by artificial palm trees and crepe paper drapery. In just fifteen minutes, the entire building was engulfed in flames. The reason so many people died in the club was because they were unable to exit the club. The two revolving doors leading into and out of the club were blocked by a mass of frantic patrons. Many of the safety features we take for granted today, such as fire sprinklers, were simply not used in the 1940’s. In addition to the many patrons, workers, and locals, cowboy actor, Charles â€Å"Buck† Jones died in the fire. Many soldiers on military leave were among the dead, others celebrating the Holy Cross defeat of Boston College were victims of a preventable tragedy. As a result of this tragedy, officials took major steps and advancements in fire prevention and control. Occupant capacity placards, exit lights and emergency lighting were all new rules enacted as a result of the fire. Fire sprinklers, a relatively old invention from 1874, came into widespread use as a result of the Coconut Grove. Advancements in history only come about after a catastrophic event such as the Coconut Grove Fire. This tragedy has no doubt saved millions of lives by the tough fire laws it brought about. Hopefully, history will never repeat itself, and we will all live to never see such an event again....

Causal Argument video games make children obesity Essay

Causal Argument video games make children obesity - Essay Example All the above causes have been substantively evaluated and proven to have a direct impact on obesity; however, debates have recently ensued, concerning the relationship between video games and obesity. According to a study by WHO, video games are the leading cause of obesity in young children and teenagers; the research further shows that a third of children in different parts of the world are overweight (Ingham). Video games make children fat, given that screen time takes away time for healthy lifestyle habits such as dieting and vigorous games. This paper will examine the premise that video games make children fat, by highlighting a number of facts in the relationship between obesity and video games. One way in which video games cause obesity in children is that video games replace active play and exercise, thus making the children physically unfit. It is advertent knowledge that obesity is high in those people who do not exercise regularly to flush out excess calories in their bod ies (â€Å"Obesity’). This is so because vigorous physical exercises require a lot of energy; the body can only get by burning the excess fats stored in the body as an alternative source of energy. Physical activity also tends to reduce the levels of hunger in obese individuals, besides enhancing their bodies’ ability to metabolize fats. ... Many studies have recently shown that, on average, children absorb up to 163 more calories when playing video games than they would when not playing (â€Å"Video games make kids fat – study†). This trend has been linked to the emotional stress that video games have on children, creating the need for a reward; unfortunately, children tend to eat mainly sweet and fatty foods thus further aggravating the risk for obesity. Dietary strategies are not an option for children who are involved in video games because, being highly addictive, the video games make children insensitive to nutrition. The glee of fatty, sugary foods is every child’s ultimate reward for the extreme mental and emotional stress that accompanies playing video games. Coupled with a lack of vigorous physical exercise, excess calories in children are a complete recipe for obesity. Obesity also results from psychological factors such as negative emotions of boredom, anger or sadness (â€Å"Obesityâ₠¬ ); all these emotions are common in children during video games. Studies have shown that many overweight people usually have emotional or psychological problems, which affect their eating habits accordingly. When playing video games, children are prone to extreme emotional stress or psychological problems, which emanate from their high involvement in the video games. For instance, a simple act of losing a fight in a video game may provoke feelings of anger or sadness in children, thus causing emotional instability. In the event of such emotional or psychological instability, children often tend to act out in defiance response to the feelings of loss, anger or sadness. In most cases, children will respond to negative feelings of anger and frustration by eating more

Definitions - Essay Example Na+ (sodium ion) is a positive and major ion in fluids outside of body cells. Its major function is to regulate water and fluid levels in the body. Na+ is involved in transmission of nerve impulses (Ganong, 2005). Normal sodium levels in the body is between 135-145mmol/L. High levels of Na+ in the body results to hypernatremia while low levels result to hypernatremia. K+ is a positive ion found inside of body cells. The main function of K+ is to regulate heartbeat and body muscle function. Normal body levels of K+ is between 3.5-5.0mmol/L. An increase in body levels of K+ results to hyperkalemia while a decrease below normal results to hypokalemia. Increase or decrease in K+ levels results to irregular heartbeats known as arrhythmias and can also result in nervous system impairment (Ganong, 2005). Ca++ refers to ionized calcium in the serum. Its main functions are for blood clotting, transmission of nerve impulses, cell membrane permeability and muscle contraction. Normal blood calcium level ranges between 2.2 -2.6mmol/L. An excess of calcium ions in the serum results to hypercalcemia while a deficit results to hypocalcaemia. A decrease in serum calcium levels results to neuromuscular irritability. Phosphorus (P) main function in the body is it gets distributed as Adenosine-triphosphate which is the main chemical energy for the body. It is a major component of DNA and RNA. It is also essential for teeth and bone formation. High levels of phosphorus in the body results to increase risk of cardiovascular diseases. Normal values of phosphorous in blood range from 2.4-4.1mg/dL (Ganong, 2005). ADH- antidiuretic hormone also gets called as arginine vasopressin. It becomes secreted in the posterior pituitary gland. It plays a key role in regulating body water by reducing its loss through urine. It stimulates water reabsorption in the kidney tubules. Artrial natriuretic hormone refers to a cardiac hormone whose gene and receptors get found
