The Current Crisis Sheds More Light on Macroeconomics than vice-versa Essay

The Current Crisis Sheds More Light on Macroeconomics than vice-versa - Essay Example On a personal stand, it would be said that indeed the current crisis sheds more light on macroeconomics and that the various macroeconomic conditions practiced across the globe could greatly be attributed to why the global economic state has not seen any impressive growth over the few years. Indeed, instead of amassing the overall aim of instituting various macroeconomic policies to alleviate poverty and make the economic conditions of countries and its populaces better, certain critical misplaced priorities and mismanagement on the part of regulators of macroeconomic conditions have led to a total failure of the ambition. Today, the whole world seems to be in a shamble and economists continues to argue on which line of action is the best – whether macroeconomic conditioning or microeconomic conditioning. In the following text, specific macroeconomic condition, the roles they were expected to play in influencing global economic growth, and how they have failed and created cris is will be looked at. Again, specific contributing factors to why dependence on macroeconomics could not help but led to global economic crisis will be discussed. Finally, recommendations shall be made on how to revive the crisis through macroeconomics. Assessing Specific Macroeconomic Conditions and how they relate to Economic Crisis National Output and Income The output and input of a country is a major indication of the performance of the country economically. Given any period of time; mostly over one year, each nation produces certain about of viable product. Some of these viable products are goods whereas others are services. To find the national output of a particular country, the total production of viable products is summed up. The reason for using the national output to determine the macroeconomic performance of a country is the reason that the viable products, be they goods or services are considered to be tradable products that can yield the country economic income and re venue. National output is therefore considered to be an economic value. In light of this, Riley (2006) posits that the national output can be used to determine the value added to the economy of a particular country. He defines value added as â€Å"the increase in the value of a product at each successive stage of the production process.† This is where the need for using the national output to create wealth and thus alleviate a country from economic crisis and hardships come in. This assertion is made against the backdrop that the value added is expected to improve all aspects of a country’s production process and thus make the economic lives of the citizenry at all levels better. It is for this reason that the value added and national output are used to determine the gross domestic product of a nation. Again, the national output is closely related to national income because it is expected that the production rate and production proceeds of a country would determine how much the country will earn on the global economic market. For each sale made, there is an added income to the national economic coffers. This is one reason why the national output is easily used to determine the gross domestic product of a country. According to Riley (2006),†this measure of GDP adds together the value of output produced by each of the productive sectors in the economy using

Why the Operations of the South Sea Company Proved to be Financially Essay

Why the Operations of the South Sea Company Proved to be Financially Unsound - Essay Example The purpose of the essay is to test the ability of the researcher to assimilate information and to order it in support of specific arguments. Students are expected to read the book, entitled A Very English Deceit: The South Seas Bubble and the World’s First Great Financial Scandal, written by Balen, M to answer the essay question. The objective is for students to think out the answer themselves, using general knowledge and plus material from Balen. The essay contains a clear, concise arguments on the subject. Therefore, the researcher concluds that there are similarities between the collapse of the South Sea bubble and the bankruptcy of Enron. Both companies seemed financially more secure than they actually were. They were companies that were attractive to investors, the South Sea Company due to price of it shares at the height of the bubble, Enron because of its size and the diversity investments. Both companies also presented themselves as being sure fire winners for investo rs, the South Sea Company inflated its own share prices, Enron fiddled its accounts to hide its mounting loses. Both companies believed that they bribed the right people in the right places and did not ensure that their books balanced enough to allow survival when times were harder. The South Sea Company had no source of income and no coherent or sustainable strategy; all it had was shares and monopolies that were worthless. In conclusion, Enron had strategies that did not work; the South Sea Company only had confidence amongst its naà ¯ve investors.

Religious Education Essay Example | Topics and Well Written Essays - 1250 words

Religious Education - Essay Example In religious education, there are many aspects wherein the use of technology plays a very important role, maybe not the primary role but one that would further improve religious edification a long way. Just as ordinary internet surfing could seem so pointless; it can actually be utilized to serve as an avenue to propagate God's words. There are already some websites that enable Bible verse searching where in you can actually read the Bible in different versions and multilingual translations. One of these websites is the American Bible Society. In one of their homepage ads it says, 2"Bible poverty is as widespread as physical poverty". Imagine what difference it would make in society if the greater part of the youth is searching the internet for Bible verses instead of watching pornography online. Millions of websites are hosted over the World Wide Web for different operations; mostly for business and personal use some are even scams. It's amazing how we can take advantage of this tec hnology to counter many malicious undertakings by making Christian doctrines available and easy to access. If the word of God is made more visible, noticeable, and most of all, accessible, it would not merely be a book hidden in shelves inside people's houses, and surely more people would pay attention to them at the least. Another impressive Another impressive technology that is being used in religious education is the PC Bible. It is a program that can be installed in your personal computer wherein you can type either keywords or passages and it will come up with related Bible verses in selected versions. I personally use the digital King James Version in my computer and I find it really useful. This is an effective instructional material for religious studies, since running the application is fast and the screen can be displayed using an LCD or LED projector. Instead of the conventional overhead projector wherein you have to use acetate slides, the LCD (Liquid Crystal Design) projector is multimedia and can project slides in full colors and even videos. LED (Light-emitting Diode) projectors, on the other hand are more sophisticated and versatile. 3Sony has developed the world's smallest LED projector. Measuring just 410cc it is equivalent to that of two business cards and shorter than a standard ball pen. The state-of -the-art technology in these types of projectors also improves the quality of instructional media that we use for religious education. Although it is good habit to bring the actual bible, it would be practical to have a PC Bible installed in the office or school computers. It does not even have to cost, all you need is an internet connection and it can be downloaded in multiple sites. There are some materials and software that can be bought, like the 4Bible Dictionary and PC Study Bible from biblesoft.com, but a lot of sites are giving the PC Bible for free, like 5wareseeker.com or 6cnet. For advanced religious studies, the use of carbon dating is another state-of-the-art innovation. This is an amazing breakthrough which is being used mostly by Bible scholars to accurately date back some recovered artifacts, scriptures as well as objects and even places. Catherine Brahic expresses her amazement in an article upon the discovery of Solomon's mines which were confirmed

Implementing And Leading Change Management Essay

Implementing And Leading Change Management Essay Organizational Change is an important issue and within organization. Changes can due to many ways such change in management system, change in accounting system, change in market demand and change in competitors in the market. Organizational is an action or set of an action for the reason of changing the direction or process of the Companys work. In addition, change is a fact of companys life. Due to survive of the organization it has to change the way it works. Change in organization may affect the business strategy of the organization, and the process companies carry out to accomplish that strategy and the workforce engage.

However, well panned and implemented change ensures organizational survival in modern days competitive market. Change can produce many benefits for the organization such improved and better competitiveness, better financial performance, satisfied employees and higher level of customer. Benefit may take long time to achieve and period of transition is time of disturbance uncertainty. Thought, change is not always positive but it can be handle such a way that strength than weaken the commitment of the people to an organization. Therefore, change process of the organization must be managed in order to keep the company moving towards its new vision and its stated objective.

From five only three (red circle in Figure 2) can be improve by the change leader; Employees resistance, communication breakdown and staff turnover during transition. Table 1 presented the overview of the leadership role in terms of obstacles. Figure2: Obstacles Experience during Major Organizational Change Change Obstacles Leaders Role Employee Resistance †¢ Leverage relationship with team to address employee concerns on a personal level. †¢ Ask for employees feedback and react to their concerns honestly and openly. †¢ Review the section on Managing Change in this guide.

Change Management Model: There are many models available to help lead change. The main common and used model of change management is Kotters Eight Steps of change management. This model of change management given below (Kottes, 2006): Step 1: Establishing a Sense of Urgency First step of the change management is help other to understand the need for change and act immediately, Do SOWT analysis to identify competitive realities and then identify and discuses possible dangers. (Kottes, 2006). Step 2: Creating the Guiding Coalition Second step of Ktters model is to make sure there is powerful group leading the change, individual with leadership skill, credibility, bias for action, authority and analytical skill, then build a team and forming influential guiding union and getting the team to work together for a common goal (Kottes, 2006). Step 3: Developing a Vision and Strategy The third step is to explain how the future will be unlike from the past, and how you will build the future realism, creating a vision to help direct the change effort, getting the vision and strategy right and developing strategies to accomplish the vision (Kottes, 2006). . Step 4: Communicating the Change and Vision To make sure that the as many as employees understand and accept the vision and strategy arise from change, a sound communication is needed between leadership and workforce to communicate vision and strategy (Kottes, 2006). . Step 5: Empowering Broad-based action: The fifth stage is to remove as manay as barriers possible than it is easy to make a vision into reality. This step help to allow to act getting rid of obstacles and encourage risk taking and modify structure or system that undermine thee change vision. (Kottes, 2006). Step 6: Generation Sort-term wins Sit step is to create visible unambiguous success and plan for generate short term achievements and achieved them then recognise and reward those employees (Kottes, 2006). Step 7: Consolidating gain and Produce more Change Seventh stage is to press faster and harder after the short term achievements, adjust improvements and sustain the momentum for change. Also, Use increasing integrity to change all systems, structures and policies that dont go well together and dont fit the transformation attempt, Hiring, promoting and developing individual who can realize the change vision, reinvigorating the procedure with new change agents, thems and project (Kottes, 2006).

Managing the Emotion in Change: There are many models to guide thinking on how people cope with the emotion cycle of change. Bridges (2003), has provide a model showing how people react in the time of change. He has divided Transition time in three phases (Figure 4); letting go/losing/ending of the present position, a disorienting or neutral zone and a new beginning. Figure 4: Bridges Three Phases of Transition (Bridges, 2003) This model transition mode reviews the emotional impact over time and the leaders role in change management. He distinguished difference between change and transition. Transition deals with oly psychological impact of the individual but one the other hand change is situational and may happen without the people (Bridges, 2003). Phase 1: Ending/Losing/Letting Go In the first phase (ending/losing/letting go), workforce of the company must come to a point where they can let go of the past situation because until they let go they will not able to move on towards future. Possible reaction from employees might be; fear, resentment, apathy, loss and sense of shock. In this phase leader must identify what individual will losing and accept individuals reaction and find a way to compensate (Bridges, 2003). Phase 2: The Neutral Zone Second phase is the Neutral zone, where employees are in gap between past and new. In this position old system does not work and new yet to launch. Possible reaction from individual might be anxiety; motivation level comes to low; confusion; but have some hope for future (Bridges, 2003). Phase 3: The New Beginning Final phase is the New Beginning phase; here employees start to show emotional commitment for the new state. Possible reaction might be; new identity, new energy and sense of purpose. In this phase leader must explain the new beginning, continuous communication the vision, develop a new training plan and give opportunity to the employees to play a part in transition process (Bridges, 2003). 3.6. Leadership Role in Change Management Process: Successful organizational change depends on leaders of the change project who have direct authority with employees going through the change. The following are some of the major roles leaders may play as they drive change in the company; Leader must be the role model of the team working for the change transition. Leader must be willing to go first and lead the fellow workers in the process. Leader must be self aware and deliberate. Leader is a decision maker. Leader control resources such as, workforce, budget, equipment available for transition period of change and have full authority to make decision how to handle them. During change, leaders must control their decision-making authority and choose the preference that will support the project. The Decision-Maker is influential and gives priorities that support change. Leader is a motivator to the employees. Leader gives motivation for the change to happen. Leaders create an image importance about change and show commitment and passion to get things done. Leader is an enforcer in change management. Leader hold individual accountable for the change with authority. Perfect leader understand that change will not happen if they do not fulfil the roles the authority can do.

Michele Cliff, Sidney Mintz and Antonio Benitez-Rojos Writings :: Caribbean Race Racial Issues Essays

Michele Cliff, Sidney Mintz and Antonio Benitez-Rojo's Writings With a focus on articles written by Michele Cliff, Antonio Benitez-Rojo, and Sidney Mintz. Michelle Cliff, "If I Could Write This on Fire, I Would Write This on Fire," and Abeng Antonio Benitz-Rojo, "From plantation to Plantation"; Sidney Mintz, "The Caribbean: A Sociocultural Area"; On this island of Black and Brown, she had inherited her father’s green eyes—which all agreed were her "finest feature." Visibly, she was the family’s crowning achievement, combining the best of both sides, and favoring one rather than the other. Much comment was made about here prospects, and how blessed Miss Mattie was to get herself such a granddaughter. The legacy of the plantation, the class struggle between dark and light skinned, the different lifestyles of city and country people, and the lack of a cohesive culture are all ideas toughed upon in the writings of Michele Cliff, Sidney Mintz, and Antonio Benitez-Rojo. The distinct difference in styles is what separates these writings. Cliff writes from the viewpoint of an islander, while Mintz and Benitez-Rojo write from a European point of view. All three authors begin by "telling" the history of the region in different ways. Mintz describes the Caribbean using nine distinct similarities, that he feels all islands have in common. He paints a picture of explorers "island-hopping" and discovering characteristics of each island. Mintz goes on by saying that the sole purpose for colonization was the plantation and the products of that plantation (mainly sugar). He continues by stating that the Caribbean is "western society" formed by European ideals and thoughts that were infused into the everyday life of the islands and its inhabitants. He says, that because of this heavy European influence, the Caribbean has no real culture. Its culture was formed by the teachings of European ideals and the remembered African tradition, which they brought over with them. Benitez-Rojo speaks of a rhythm that is present in the Caribbean. He does not believe that there is a Caribbean culture. He does say that the people of the Caribbean have a certain rhythm to them. "It is rhythm that puts all the Caribbean peoples in ‘the same boat,’ over and above separations imposed on them by ‘nationality and race,’ it is rhythm—not a specific cultural expression—that confers Caribbeanness." Cliff doesn’t really go into a description of the whole Caribbean. She tells the story of a light skinned Jamaican named Clare.

He does not believe that there is a Caribbean culture. He does say that the people of the Caribbean have a certain rhythm to them. "It is rhythm that puts all the Caribbean peoples in ‘the same boat,’ over and above separations imposed on them by ‘nationality and race,’ it is rhythm—not a specific cultural expression—that confers Caribbeanness." Cliff doesn’t really go into a description of the whole Caribbean. She tells the story of a light skinned Jamaican named Clare.

How does Priestly create dramatic tension in An Inspector Calls Essay Example

How does Priestly create dramatic tension in An Inspector Calls Essay Example How does Priestly create dramatic tension in An Inspector Calls Paper How does Priestly create dramatic tension in An Inspector Calls Paper Essay Topic: Literature JB Priestley creates immense tension in his 1945 play, An Inspector Calls, with didactic purposes to question how society deals with individuals and their problems. The growing tension between the characters on stage is reflected in the audiences awareness of gap between the rich and the poor. Priestley is able to criticize society boldly, as he distances the characters on stage with, tone of speech, and the whereabouts of the characters. This means he can additionally take advantage of societys regimes and the tension portrayed as he writes the play in 1945. An Inspector Calls is set in 1912 at a time when society was strongly capitalist, and class, exceedingly, divided the world. It was written in 1945 at the end of the unspeakable Second World War. As the play is written at this time it allows Priestley to take advantage of creating tension by questioning conservative policies and class distinction. Between these dates Britain was involved in two world wars, which caused major upheaval in the world. Priestley had seen the unpleasant tragedies and was overwhelmed and concerned that the lesson of the war remained unlearned: and did not lead to improvement of the lives of ordinary people, but yet to another war. Due to the fact that Priestley was a socialist, he felt that society should be equal and class barriers should be broken. Priestley creates vivid tension with the use of setting and props, the Inspector, Societys double standards, speech and dramatic irony. However another way Priestley endures tension is by playing around with a challenging genre. Firstly in the setting of Act One, wealth is immediately established into the atmosphere of tension in society, indicating that the characters are wealthy by living in a large suburban house. To the audience this could show an instant sign of snobbery. Many more values are added to show wealth and symbolism of the characters. Part of the stage direction and props is the cigar box. It states symbolism of power establishing Mr Birling as an authority figure, which sets up tension when the Inspector interrogates him. The inconvenience of the dining table is mentioned and suggests the inflexibility that later shows about the set ways of Mr and Mrs Birling. The table manages to create tension as it is referring to the atmosphere and nature of the family. It reflects the solid unit which is uncomfortable, much like the subtext and unity of the family which later crumbles under the society of inspection. It creates tension by becoming awkward and artificial, just like the family. The fireplace has a colossal deal of importance in the play. It can be dramatically seen as a juxtaposed paradox to the holocaust. It represents a flaming inferno and the burning down of societys barriers. Later on in Act Three the Inspector gives an intense, dramatic and extremely heated speech. He mentions fire and blood and anguish which could be referred to the fireplace that is lit throughout the play. It is almost a continuous heartbeat that is heating up the tension and conflict of characters. It is as if the fire is spreading like a disease from one person to the next as they start to confess one by one. The fireplace also has a correlation with Evas death. She apparently died by being burnt burnt her inside out which relates to a fire and produces a mass of tension. The lighting in Act one is notified and thought about deeply to create a vast amount of tension and unease. At first the lighting should be pink and intimate creating comfort but then it switches to harder and brighter when the inspector comes in. The stark lighting becomes alarming to the family and creates the effect as if they are put under a microscope. Also the vivid lighting exposes the characters and societys flaws as well as their own. However later as the Inspector arrives with the hard-hitting light it causes the family to be literally under the spotlight and makes the harsh clear reality evident. As soon as Inspector Goole steps foot into the room his presence certainly ups the intensity between each other and the Inspector. To begin with his name is eerie as he is announced as Inspector Goole. It is a deep name as you are reminisced of the word ghoul and can be linked together which creates a spooky aspect of his name and becomes daunting. He creates at once an impression of massiveness, solidity and purposefulness immediately the Inspector creates unjust tension in the room and is profoundly hard hitting. He manages to have a concentrated effect on the character as well as the audience and takes everyones undivided attention. He speaks carefully, weightily, and has a disconcerting habit of looking hard at the person he addresses before actually speaking. Here the inspector continues to keep giving a harsh force on each individual especially when tension is created between the Inspector and Birling. When speaking to Birling, Birling begins to feel manipulated as he starts to use hyphens when speaking, and not acting so abrupt. However Birling is very observant and weary of the Inspector and as soon as he finds a error he immediately becomes stuck up. For example Birling realises that the Inspector is new and takes advantage and becomes arrogant. The Inspector has a defined way of asking people questions, it is very calmly said but in an aggressive mode. He is able to bring justification into his etiquette act. Throughout the play many terms are referred to societys double standards. In the Edwardian Era sex before marriage was frowned upon and was not traditional, in this case Gerald was playing in between two women. It was acceptable for Gerald to have a relationship with Sheila as they were being truthful and loving to each other and are of the same class and social hierarchy. However when Gerald began seeing his mistress Daisy Renton (also known as Eva Smith) it was not acceptable to have a full, sexual relationship as she is of a lower standard in society. He should have subscribed to Edwardian values and kept Sheila as his love, conversely he had an affair with Daisy. Ironically Eric refers to prostitutes as fat old tarts-this is another ambiguity and double standard used and shows how the women are inferior. In Edwardians views Eva (Daisy) was seen like a prostitute because she stayed at bars where prostitutes hung out. After all the talk of sex and prostitutes the house becomes corrupted as Priestley emphasises the double standards. Another double standard used in the play is the fact that women seem too feeble to men. They need to be protected against words of evil as if they cannot provide or look after themselves. Birling sends the two women out of the room, as they need to be protected and defended, as they are the weaker sex. He does this mainly to relieve the tension of his women hearing all the foul talk. As well as the double standards the ways in which characters spoke to each other in An Inspector Calls. Priestley conveys each character differently and he does this by their speech. The Inspector indicates a lot of tension to the family as he is very calm and collective which stresses them out, as they are not. This shows that he is in control and this unfortunately makes them even more distressed, the Inspector is almost like a Priest. Countless stage directions are used mainly adverbs like: aggressively, defensively, abruptly, eagerly and uneasily are used which are shown creating dramatic tension in numerous ways. The way in which the characters speak to each other has many different effects as Mrs B is awfully snobby, Mr Birling is arrogant, Sheila feels like she is completely guilty for everything that has occurred and so on. Shelia says Thats what you say this creates tension in the use of language and emphasises you you imply that she doesnt believe him. Other tense moments are created: Eric suddenly guffaws this stage direction and interjection is slightly bewildering and out of place. It creates tension as it doesnt interlock with the atmosphere and Eric is having his secret amusement. Making everyone perplexed, but intrigued. Another effect created when characters are speaking is the use of hyphens/dashes. It creates tension as it interrupts language pace and the structure causes tension. Furthermore it shows that there is anticipation in their speech and there is something to hide or break down in communication. Lastly JB Priestley constantly refers to the use of dramatic irony. Mainly Birling is the upholder of his naivety and complacency. Birling is extremely ironic when it comes to his arrogant monologue. It is completely prejudice and completely erroneous. I say there isnt a chance of war this is totally ironic as two years later the war started so he is making himself look like a fool. Also dramatic irony is used because as it is written later, the audience know that he is wrong and that a war was uprising then. Because of setting the play in 1912 it reminds the audience that they cant be complacent and that they have seen two world wars since the plays setting. Also Birling debates about how the titanic would be unsinkable, absolutely unsinkable and again this is totally incorrect as the titanic hit an iceberg and sunk. He also pronounces to Shelia and Gerald that when you marry youll be marrying at a very good time. Once more he has juxtaposed himself as the time that Shelia and Gerald were going to marry is not good because it would have been the time of war. Furthermore Birling describes the German officers talk as silly pessimistic talk when in actual fact it is not silly talk but truth and reality, which people should have taken into consideration and taken responsibility. So finally to conclude Priestley is able to create dramatic tension throughout Act One and the rest of the playwright with the use of props, speech and society. Priestly deliberately sets in another time but very critical of the modern society he wants to criticize. He wants to put across his views that people need to create a society, which concerns and feels responsible for each other. Priestley implies to the audience that they are all sinners as Priestley is using biblical ideas and illusions, so that a microcosm of Goole becoming a Preacher man. Priestley desired to educate people and warn them and communicate with the populous through the popular medium of the theater. But Priestley boldly manages to intensify his longed emotions for a socialist country which makes the play so tense that he cliff hangers the end making the audience wonder that the Apocalypse is the revelation at the end of the world where we will be judged for who we are and what we do.

Cleaning Ambulance essay

Cleaning Ambulance essay Cleaning Ambulance essay Cleaning Ambulance essayYou can consolidate and save money. You don’t need the toxic products some departments use.   The driving force behind selecting a chemical to clean an ambulance should be the type of organism the chemical is meant to eliminate.   With the single exception of Clostridium difficile (commonly known as C diff), which requires a chlorine-based cleaning product, most ambulance providers need only low-level productsYou should have your cleaning plan schedule to conduct cleaning regularly and effectively. The plan should contain the time, place, and items that have to be cleaned along with the indication of detergent and cleaners that should be used to clean the interior of the emergency vehicle.Decontaminating an ambulance is a process. The first step is cleaning to remove debris. Only after a surface has been cleaned can it be decontaminated using one of three types of disinfection. The first, or highest level, is sterilization. Sterilization completely eliminates all organisms and is used for equipment that will be reprocessed (or reused) and comes into contact with mucus membranes, such as a laryngoscope blade. Chemical or steam-based sterilization can be used, but the correct procedure must be followed.  Disposable items don’t need a high level of sterilization. Non-critical items would include stethoscopes or blood-pressure cuffs. Cleaning of floors, stretchers and walls don’t require the same strict standards of the highest level of decontamination.You will require a gown, protective eyewear and special gloves when used. OSHA requires that providers wear dishwashing-type gloves, not disposable ones, when using any cleaning product, even disinfectant wipes. For the most part, wipes and paper towels used in the cleaning process are not considered medical waste and can be disposed of in the regular trash, even if bodily fluids are present. Using the regular trash to dispose of this waste will significantly cut cos ts. However, every state has different regulations, so she suggests reviewing state definitions regarding medical waste. One of the most effective disinfectants is a simple bleach and water solution, mixed at a ratio of 1:100.  PresentationWhile making a presentation, I conducted the preparation for the presentation collecting the information that I will need. In this regard, I collected and processed all the information, while preparing the pamphlet. First of all, I focused on the identification of major risks and threats which emerge in the course of the work of the average ambulance team. In this regard, it was easy to identify various infectious diseases, such as hepatitis, HIV, and others which may be transmitted to the ambulance staff from patients in case of not cleaning the ambulance properly. As I informed my team mates of the risks they are exposed to, I placed emphasis on the importance of cleaning the ambulance thoroughly and regularly. I explained them that cleaning t he ambulance is the only way to avoid developing an infectious disease being contaminated through the unclean ambulance environment. At first, my team mates does not really looked anxious about what I was telling them, until I noticed that the probability of developing an infectious disease in the unclean ambulance seven times higher compared to the clean one. After that I have noticed that my team mates have started to grow interested in what I was talking about.Then, I gave them the pamphlet printed for each team mate. I gave them some time to read and look through the pamphlet. After that I told them that it is not a mere pamphlet containing the general information on how to clean the ambulance. Instead, this is a set of recommendations which they would better take into account and follow, if they want to prevent them from catching an infectious disease or having other health problems. I told them that cleaning is easy when they know how and what to clean. Then, I asked them to l ook at the part concerning the planning and scheduling of the cleaning. I told them that it should a sort of the routine procedure for them† â€Å"It’s like washing your hands before having a meal during your service. You can’t just leave your ambulance unclean because it’s your health that is at stake†.Moreover, I tried to refer to the responsibility of my team mates, who started to object me that they do not really care about those threats they expose themselves to. I reminded them that cleaning the ambulance is not just the matter of their health: â€Å"Think of patients and your team mates? Don’t you care they can get a disease because of you, because of your laziness and negligence in cleaning the ambulance?† After that my team mates seemed to be more convinced of the importance of cleaning the ambulance. Then I asked them whether they know how to clean the ambulance properly. Naturally, they immediately responded positively. Then I asked them to look through the pamphlet again and asked several questions about how to clean the ambulance properly and my team mates could not respond to all of them properly. Hence, they agreed that they should work harder on learning how to clean the ambulance properly.

Bilingual Education Should not Be Offered in Public Schools Research Paper

Bilingual Education Should not Be Offered in Public Schools - Research Paper Example Students in public schools are at an age in which most of them hardly find any interest in studies. Instead, they are more inclined towards hanging out with friends or remain busy in other outdoor and indoor activities for most of their out-of-school time. In such circumstances, it is indeed, challenging for them to develop an interest in studies offered in their own language, what to talk of subjects taught in a language that is not their mother tongue. When intricate concepts of physics and chemistry are delivered in a second language, students are indirectly made to exert much more than what would have been required of them, had the lectures been in the first language. â€Å"Immigrant pupils can become more self-reliant if courses in arts, history or music are taught in Spanish and/or deal with their cultural heritage† (Teipelke 5). Not just this, in bilingual education, it becomes even more cumbersome for the students when they have to produce all that they learned formerl y in their exams. This way, bilingual education also invalidates the conventional testing system that is thought of as a means to judge the true capabilities of students. It is so because, we can not say a student did not work hard, only because he was not able to interpret his knowledge into words in the second language. Also, speakers of the language chosen as a standard for the exam tend to perform better than non-speakers because they do not have to cross linguistic barriers in order to make their point. The potential disadvantages of bilingual education can be assessed from its impact on the US educational system as a case study. Bilingual education was introduced in the US educational system fundamentally to provide the children from immigrated communities with an opportunity to speak, read and write the language of the locals.  Ã‚  

The legalization of marijuana in the United States Research Paper

The legalization of marijuana in the United States - Research Paper Example However, there is also a giant percentage of public which believes that criminalization of marijuana possession has always been a defeated objective. It is a kind of government objective which has consumed a lot of manpower and valuable limited resources. However still, the government is nowhere close to discouraging the public from smoking marijuana. Basically, this research paper seeks to argue that cannabis should be legalized or decriminalized in the US. The paper will present and explicate multiple reasons to augment the argument that marijuana is a drug with a variety of uses and minor risks. To validate the argument, marijuana will also be compared with alcohol and tobacco as a way of demonstrating how marijuana is so much less detrimental than the latter substances and still looked down upon by the government with such intensity, which is absolutely unjustified. War on drugs, particularly marijuana, is a complete failure. It has consumed trillions of dollars to date and continues to exert more financial pressure on the American government with every passing day. Prohibition on this drug has affected society very badly because more people are reported or jailed for minor drug offenses and people have to go to extreme measures to get this drug. Many such measures often affect their self-esteem in a very bad way given the circumstances and the places they have to bear to get the drug discreetly. Research also claims that the main reason marijuana often affects users’ lives negatively is not because of the drug really, but â€Å"because of the consequences attached with using the drug† (Pitts cited in Millat). Research shows that the US government has wasted a lot of money to keep marijuana from reaching the market in the past. According to an estimate, the US government suffers a total cost of about $10 billion on an annual basis in myriad efforts to make the country free of this drug. On the other hand, the State of California produces
