Team Reflection Paper - Essay Example During the ACC 544, Internal Control System, I was a member of team C. The purpose of this paper is to describe the interaction and learning experience that occurred during this course through the team learning mechanism. I have taken over 15 courses at the University of Phoenix online at the graduate level. Each of these courses had team assignments to be performed by a small group of students of 3-6 members. I believe that the university is doing a great job in their teaching methods because it is preparing us for the workplace of the future. Virtual teams are a hot trend in the managerial field due to the globalization movement and the fact that there are thousands of global corporations worldwide. â€Å"Managing a virtual team means managing the whole spectrum of communication strategies and project management techniques as well as human and social processes in ways that support the team. During the last six weeks I had the privilege to work with an outstanding team. It was a pl easurable experience working with a great group of professionals. Starting in week 1 team C always had great communication among the members. Communication in the workplace is an important variable that must be managed well by the leaders of an organization. Communication problems can lead to misunderstanding and conflict. Team C did not experience any of these symptoms. Whenever anyone was called upon to deliver data or information everyone responded promptly. As I mentioned earlier I have been a part of several work teams at the University of Phoenix. I believe that this team has been the most functional and productive team I have ever been in. The academic results prove my premise. Team C received a perfect grade of 25/25 on five projects the team completed. I’m a good student, but I do not have a 4.0 G.PA. Team C achieved perfection due to its hard work, commitment to excellence, cooperation, outstanding communication, and concise writing. I wished I would have had these teammates with me in all my previous courses. One of the best things about Team C was the lack of an ego. In other team I have worked on somebody always wants to be the team leader without getting approval from the other members. Team C did not have that problem. I believe that the leadership responsibilities were shared equally among the members. I loved the fact that the team member willingly divided the work parts without having anyone tell them to do things they did not want to do. Another great aspect about the team was the punctuality of the deliverables. At the University of Phoenix online the members of study teams depend on each other. If one member fails to deliver their work on time it creates a chain reaction that affects the quality of the work of the team. Team C cared about each other and respected the academic well being of the other members. The perfect grade the team was able to achieve in the five assignments will increase the chances of all the team members obtai ning a passing grade at the end of the course. I enjoyed working with this team because there was mutual respect among all the players on the team. The team was very organized throughout the entire course. This help the communication process because everyone always knew what they were supposed to do. I took initiative prior to week four and week five projects of creating an outline a few weeks before of how to separate the work in the team. This strategy worked well as everyone knew

Roles Of The Un During The Cold War Politics Essay

Roles Of The Un During The Cold War Politics Essay Maintaining peace and order in the international system have always been the concerns of the states and statesmen.But ubiquitous anarchy and practicing poltics of absolute gain rather than mutual gain by the states have been major hindrance in achieving desired goals.First world war(1914-18)deteriorated the condition of peace and security in the international system.Seeing the catastrophe of the war and future possiblitiy of such devastating wars,the idea to set up an international organization,able to bind the states by an universally agreed set of laws and conduct came in the mind of then the US president Woodrow Wilson,he propsed:a general association of nation must be formed under specific covenants for the purpose of affording mutual guarantees of political independence and territorial integrity to great and small states alike.This association of states was called League of Nation,which could not live up to its commitment to maintain order in the international system because of its few shortcomings as a general feeling existed that the league was an imposition of the victorious countries of first World War,Germany and USSR both made a late entry,and the US was not part of the league despite the fact that creation of the league was the brainchild of the US president Woodrow Wilson.Other reasons for the fall of league were acute economic crisis of that time and lack of commitment of the member states of the league. As the League of Nations was a product of first World War,so was the United Nations a product of the second World War.During the the war period,the idea that a new,major international organization would be needed to maintain peace and security in the post-war world,gradually gained popularity among the allied powers.The term United Nationswas coined by the US president Roosvelt.Its purpose,as laid down in article 1 of the charter,are: 1.To maintain international peace and security; 2.To develop friendly relations among nations; 3.To achieve international cooperation in solving international problems of an economic,social,cultural or humanitarian character; 4.To be a centre for harmonizing the actions of nations in the attainment of these common ends. The maintenance of international peace and security has been quite logically placed at the top of the list of purposes of the UN because in the absence of peace and security none of its other purposes can be realized. For the maintenance of international peace and security the UN will take effective collective measures for the prevention and removal of threats to the suppression of acts of aggression or other breaches of the peace,and to bring about by peaceful means,and in conformity with the principles of justice and international law,adjustment of international disputes or situations which might lead to a breach of peace.(Article 1.1) Fearing that theseeffective collective measureswould provide valid ground for frequent military and sometimes unjust actions too,Article1.2 of the charter encourages more positive steps asdevelop friendly relations among nations based on respect for the principle of equal rights and self determination of people.The charter has specified certain methods too for the peaceful settlement of dispute among nations.These arenegotiation,enquiry,mediation,conciliation,arbitration,judicial settlement,resort to regional agencies or arrangements,or other peaceful means of their own choice. Since the purpose of maintenance of internal peace and security can not be realized under conditions of social unrest,economic backwardness and cultural drawbacks, the charter enjoins that the organization will seek to solve international economic,social,cultural and humanitarian problems on a basis of cooperation among nations that will promote and encouragerespect for human rights and for fundamental freedom for all without distinction as to race,religion,sex or language.(Article 1.3) Despite all the obligations and a benevolent charter it has been observed that many a times,UN just becomes the instrument in the hands of powerful states and its members commitment to peace and security remains a sincere but unlikely to be fulfilled hope.The General Assembly,the Economic and Social council and the Trusteeship council can only make recommendations but have no authority to make binding decisions.Only the security council has the authority to make binding decisions.But it also can be paralysed at any moment by any of the permanent members through the application of the veto. United Nations has seen its worst loggerheads and strong disagreements during the cold war,a short analysis is described here: United Nations:During Cold War- During the Cold War,the concept of collective security by which aggression against one member is met with the resistance by all,underlies the chapter 7 of the charter,which grants the security council the power to order coercive measures-ranging from diplomatic,economic,and military sanctions to the use of armed forces,in cases where attempts at a peaceful settlement have failed. Such measures were seldom applied during the Cold War, however, because tensions between the United States and the Soviet Union prevented the Security Council from agreeing on the instigators of aggression. Instead, actions to maintain peace and security often took the form of preventive diplomacy and peacekeeping. The Korean war:At the end of the second World War,Korea split in to two parts. The south part was supported by America while USSR dominated the north.Though the UN involves itself to the Korean matter in 1947,before the partition.It declared that UN would be there to oversee the elections for the whole country to ensure the credibility of the elections.USSR did not allow UN observers in northern part which was under its influence as a result,UN declared that results from north part were not acceptable as they had not been independently observed.By the end of 1948 Korea split in to North Korea and South Korea.North Korea was supported by communist USSR and China.The south was supported by America and was considered by the west only democratic country out of two.Both governments claimed the right to govern the other.Meanwhile North Korea backed by USSR and China attacked South Korea in 25 june,1950.When the Security Council met for the Korean regard,USSR delegation did not attend the m eeting.Therefore the use of veto by the USSR did not occur and America instantly claimed that North Korea had broken the world peace by attacking South Korea and called on North Korea to withdraw its forces from South Korea.On June 27th 1950,America called on the UN to use force to get the North Korea out as they had ignored the appeal of the internation community to withdraw their troops.USSR could not use its veto as they were still boycotting the UN.The UN now had to formulated its plan to to attack North Korea.Seventeen member states provided troops under UN joint commond,the UN force was dominated by the US troops its commander being American general Mac Arther.The UN troops effectively pushed North Korean troops out of South Korea.Mac Arther then advanced to the North Korea,ignoring the warning from China.As a result,situation got dramatically complex and Chinese attacked UN troops and managed to push back the UN forces.In 1953 a cease fire was agreed.the UN received much supp ort for taking robust action but surely not from the USSR and its allies.South Korea regained its independence and contuned to be supported from America.USSR later dropped it boycott of the Security Council and rejoined it during the Korean war.USSR blaimed UN security general Trygve Lie to act out of his powers.The Korean war gave a clear indication that the rivalry between the the two super powers would further drag on and mar the effectivity and credibility of the organization. Suez Crisis:On 26 July 1956,Egyption president Gamal Abdul Nasser nationalized the Suez canal,the canal was owned by Suez canal company which was controlled by the British and French interests.The crisis was provoked by American and British decision not to finance Egypts construction of Aswan high dam,as they had promised.In response to Egypts growing ties with communist USSR and its ally Czechoslovakia,Nasser reacted to American and British decision by declaring martial law in canal zone and seizing control of canal company,stating that the tolls collected from ships passing through the canal,would pay for the dams construction within five years.Britain and France feared that Nasser might close the canal and cut off shipments of petroleum flowing from Persian gulf to western Europe.When diplomatic efforts to settle down the crisis failed,Britain and France secretly prepared the military action to regain control of the canal and if possible,to depose Nasser.They found a ready ally in Israel whose hostility toward Egypt had been exacerbated by numourous raids by Egyption supported commandos in near past. On 29 oct.1956,Israeli forces invaded Egypt,routing Egyption forces.British and French following their plan,demanded Israeli and Egyption forces withdrawing their forces from canal and they would intervene to inforce cease fire ordered by the United Nations.On 5th and 6th Nov.British and French troops landed on Port Said and began occupying the canal zone.This move was soon met by growing opposition at home and by the US sponsored resolution in the UN(made in part to counter Soviet threats if intervention),which quickly put a stop to the Anglo-French action and brought a ceasefire in action and 6000 UN troops from nine countries known as`Bblue Helmetswere deployed it also established the first United Nations Emergency Force(UNEF)to secure and supervise the ceasefire.Suez crisis again warned that when the powerful states work for just vested interest(as Britain and France did in this case)global peace is always at stake and global peace is greatly threatened by not just failed and non democratic states but by democratic and modern states too. Congo Operation:The role of UN in Congo conflict has been quite controvisial.Congo till 1960 had been a Belgian colony.It became independent on June 30,1960.Belgians left the country in the state of complete confusion and disorder.This disorder broke out and Belgium sent its troops to the Congo,stating that its aim was to protect and evacuate Europeans.The government of Congo had not invited foreign troops.This was an illegal act as Congo was an independent country by then.Problem worsened when the mineral rich province of Congo,Katanga was declared independent by one leader Moise Tshombe who lead the people in Katanga.tshombe was backed by European companies who worked in Katanga as they hoped to take a cut from the considerable profits that could be made from mining.Katanga had the potential to make Congo one of the wealthiest African states,without it the new nation would remain poor.In such a scenario prime minister Patrice Lumumba appeared in the UN for help.The Security Council created an army to restore law and order in Congo.The army was instructed to restore law and order,stop other nations getting involved in the crisis,assist in building nations economy and restore political stability.The UN force was only allowed to use force as a measure of self defence and instructed to act impartial in any situation.Situation worsened when Lumumba asked the UN troops to crash the power of Tshombe.Secratery general of the UN Dag Hammerskjold turned down his demand.Lumumba immediately accused the UN of siding with Tshombe because of Katangas rich European componies that mined the the region.After being turned down by the UN,Lumumba turned to the USSR for help.The USSR provided Lumumbas government with weapons that gave him appourtunity to launch an attack against Katanga.Congo president Kasavubu dismissed Lumumba government for this attack and appointed the chief of the Congos army,colonel Mobutu as the new PM.Lumumba set up a rival group in the east of the country .But soon he was murdered.Through all of this the UN could do nothing as it had been agreed not to take side and fire in self defence only.Now to prevent a possible civil war,the Security Council gave permission to the UN army based there to use force to prevent a civil war occurring.Government in the centre asked the UN to provide military support for an attack on Katanga as it was well understood by then that no peace is possible unless the Katanga insurgency is solved.In August 1961,5000 UN troops launched an attack on Katanga and captured keypoints in the province.As a result of high onslaught,Tshombe agreed to talk to the government.Later Katanga was reunited with the rest of Congo. Apart from its military intervention and its consequences,the un had taken responsibility for the humanitarian programme as famine and and epidimics were endemic in Congo,un did significant work to amend the condition of the country.Though UN troops saved the country from felling in to civil war but UN had been accused of taking sides in Congo and it again showed the struggle of world powers to establish their poltical ideology in foreign land for their geo political purpose.Congo also regarded as playground of cold war politics. In short ,it has been analysed that during Cold War the UN has become a centre where America and the USSR always tried to pull each others leg to assert their superiority over the other and smaller and weaker nations always payed for their hostility.During the Cold War their situation can be compared to a group of school children,where twobig boysfighting for their dominance in the class and rest of the smaller kids looking at them with fear and helplessness.But we can not neglect the introduction of few very useful new concepts which proved to be crucial for future UN role as peacekeeping,peacemaking and humanitarian assistance. United Nations:Post Cold War Era: After the demise of the Cold war soviet leader Mikhail Gorbachev,vowed to reform his country politically and economically and reduced the east-west tension by redefine the Russias relationship with the UN.Russia withdrew its forces from Vietnam,Cuba and few other parts of the world to show its commitment to the United Nations and collective security for the second inning.Gorbachev seemed to understand the futility of being loggerheads to the America as its treasury had drained and Russia was in acute financial crisis because of the proxy war with the US. In that new atmosphere of hope and trust it was believed that at last now the UN would be able to perform more effectively and adeptly.This was the time when Boutros Ghalis An Agenda for Peace was introduced to the UN which covers:preventive diplomacy,peacemaking,peace building and peacekeeping. Gulf War:This atmosphere of trust among the member states was best seen during the gulf war when Iraqs leader Saddam Hussain invaded Kuwait with the appreant aim to occupy Kuwaits oil resources.On August 3rd 1990 UN Security Council called for Iraq to withdraw from Kuwait.But Saddam steadfastly refused to withdraw as he maintained Kuwait would remain a province of Iraq.As a response allied forces which included other Arab nations forces and led by the US reached the strength of 70000.On January 16-17,1991,the first gulf war began with massive US led air strikes.This military operation was given the nameOperation Desert StormIraqs military power soon collapsed and Kuwait was retaken by allied forces.By the time then US president George Bush declared a ceasefire,Iraqs resistance had completely collapsed.This collective operation plan was passed with unprecedented unanimity.It also strenthend the hope for the future role of the UN in maintaining international peace and security.After th e Gulf war UN also engaged itself to the problems of Iraqs minorities(Shite and Kurds)and managed the refugee problem.An indication of its broder future role. Another remarkable point about the post cold war scenario was that conflicts largely became intra state rather than inter state.first Gulf war remained an exception where Iraq attacked Kuwait. Yugoslavia Case:Conflict on ethnicity entailed so much violence and displacement of the population which Europe had not seen after the second World War.UN regisrered a late entry as it was first seen as the internal matter of the state.Security Council granted the proposal for a peacekeeping operation and the UN protection force(UNPROFOR)was established in 1992.But through out the conflict the impression grew that UN was largely impotent as carnages and bloodshed were still happening .It was also felt that international community was reluctant to intervene into intra state conflicts as they were not so much threatening global peace.Peacekeepers and humanitarian actors were attacked and theUN suffered economic crisis as well.But it at least prevented the spill over of the conflict in to neighbouring states and provided humanitarian assistance which was useful to some extent as it provided the framework for the final peace negotiation and agreements. Somalia Conflict:In 1991-92 Somalia was in total disorder and chaos as warring clans took over the parts of country.UN operation was done in a condition where there was no form of legitimate government,no security and no order.Famine and shortage of food were common.At first a small force formed by Pakistani troops(UNISOM1)was sent to Somalia to protect the humanitarian and relief workers .The Security Council resolution 794 authorized a large US led troops.This effort was labled as Operation Restore Hope or the United Task Force(UNITAF).Seeing no satisfactory development the Security Council authorized UNOSOM2 to use whatever force was necessary to disarm local warlords who refuse to surrender their arms and to ensure access to suffering civilians.Heavy army and cobra helicopters were called in by the UN command in 1993.This way UN engaged itself to the war of retaliation,an unexpected military adventure from a responsible international body.In retaliation local militia killed sever al foreign journalists and aid workers.At last UN had to withdraw its troops in March 1994 which further deteriorated already precarious condition.UN performance has been very mediocre and its morale was loose.In Somalia UN broke one of its principle as it intervened in Somalia without any request made by the state.It also showed its institutional weakness and learnt that it has a lot to learn about the situation of intra state war which was rather a new entry in the international system after the end of the Cold war. All we can say in short that they ray of hope which was generated after the Cold war regarding the responsibility and effectiveness of the organization,has been diminished as in intra state conflicts the UN has not performed well but one thing one must keep in mind that The UN role in the global system has been ever changing thus many a times creating difficulities for its functioning.Since the 1950s the working of the UN has been greatly affected by the advent of new members from the third world,the impact of changing superpower relations which have diminished or enhanced its role from time to time,the problems it has faced in peacekeeping,the budgetary crisis it has faced over the years,political conflicts inside the organization as once between the east and the west and now between the north and the south,the disintegration of the Soviet Union and unprecedented war on terror.All such factors are responsible for some times effective but many times poor performance of the organizati on. In resent past too genuine questions have been raised about the creadibility of the organization.Mainly in 2003 when the US attacked the Iraq for the second time.Then the US president George W.Bush did not look for the diplomatic effort and did not seek UN permission to launch attack on an independent country.The US payed no heed to the objections raised by other states of the Security Council.Contrary to the first Gulf war,this time most of the states did not support the attack as it was done on no solid ground.The US president George W Bush stated that Iraq had weapon of the mass distruction and Saddam had ties with Al Qaeda.WMDs have not been found till date and Saddam was such a figure that Al Qaeda or Osama Bin Laden would have loved to hate for his secular views in politics.So both the statements of then president Bush can easily be classified as the lies of the decade,dedly lies as they claimed several civilian lives in Iraq. This kind of behavior accentuates the problem of eliticism in the organization,But as the adage goes by thatsomething is always better than nothing.We can only envisage the situation of absence of the UN.In such a condition the wars and conflicts which have been averted by the UN efforts,would have been full fledged wars and claimed innumerable lives.Another example of the UNs commitment to the more stable world order is seen in the resent past with the creation on UN Peace Building Commission in 2005 to help the countries who have just faced the conflict and who has the great chance to lapse back into conflict situation.This commission is set to assist such countries in transforming in to peaceful society from the conflicted one.Though the numbers of such successful efforts are not too high but if an international organization can become a reality as a result of the genuine effort.It can surely be transformed in to more effective machinery but commitment,sensible enthusiasm and hope for a better and secure future are needed one more time.

The Effects of Tobacco :: Papers

The Effects of Tobacco The smoking of tobacco became prevalent early in this century. The production of flue-cured tobacco, the development of cigarette rolling machines, and a public health concern over tuberculosis germs being spread through the cuspidors associated with snuff and chewing tobacco, all contributed to an increase in cigarette smoking. As smoking became more common, health problems emerged which seemed to be related to smoking. In the 1950’s, sir Richard Doll, a British researcher, studied the smoking habits of more than 34,000 physicians and found a strong correlation between smoking and disease. Throughout the 1950’s, research data on the effects of tobacco on human health hazard of sufficient importance in the United States to warrant appropriate remedial action." Since then, each Surgeon General has spoken out against smoking; the current Surgeon General proclaims smoking to be the number one preventable cause of disease and death. Medical science is in general agreement that use of tobacco endangers one’s health. Lung Cancer was the first health effect to be linked to smoking. Subsequent research has linked tobacco usage to heart disease, emphysema, and several other forms of cancer. Recent research has even suggested harmful effects to unborn children of smokers and to those non-smokers exposed to the side-smoke of smokers. One of the benefits of a free society is the freedom of choice for adults, so long as this freedom does not deprive other persons of their freedom The decision to smoke might appear to be one of those choices, since it is usually through that the health risks of smoking are borne largely by the individuals making the choice. Factors that complicate the simplicity of this argument are: 1) Smoking is a social custom and when one person smokes, other persons in the area are exposed to the smoke. 2) Adult smoking habits provide a powerful modeling which affects the habits of children and youth. 3) Society must bear some of the social cost (increased insurance premiums and various tax burdens) of death and disability brought about by the use of tobacco. The tobacco plant is believed to have originated in the Western Hemisphere. The cultivated species most often grown for North American and European tobacco products is Nicotiana tabacum. The leaves of the plant are prepared for smoking, chewing, or sniffing. In addition nicotine tobacco contains over 19 known carcinogens (most collectively known as "tar") and more than 2,000 chemicals. Prior to European influence in the Americas, tobacco was used by the Indians of Mexico and Peru for ceremonies, medicinal purposes, and to alleviate Error! Bookmark not defined.

Scientific Sessions

Name: Ornella Hayles ID Number: 816008392 Tutor: Sheldon Pilgrim Session: Tuesdays 2-3pm3700030000 Name: Ornella Hayles ID Number: 816008392 Tutor: Sheldon Pilgrim Session: Tuesdays 2-3pm44000341947525002514604000070000455003536315690006939915370000455003536315350003520440Sci, Med & TechReflective Journal3600028000Sci, Med & TechReflective JournalSession Date: 22/01/18 Session No: 1Session Title: Introduction to Science & TechnologyIn the first session, the lecturer did an introduction of Science & Technology and an overall view of the course outline. After the introduction, I got a perspective of what Science & Technology was. At first, I thought the course was going to be essentially, about science since it was mainly being mentioned, but I was wrong. The lecturer took her time to clearly distinguished between science and technology and its importance to society or the world in general. She ensured that we all understood what she was lecturing by engaging us to respond to her questions, it appeared that she really wanted us to understand what was being taught so she went over what she said twice, two different ways which I appreciated. It helped me a lot to understand and grasp the concepts effectively. The use of visual cues seemed to work well with the class as it captured our attention and made us receptive. Through research I've come to realise scientists all have different perceptions of the word science. â€Å"Science does not purvey absolute truth, science is a mechanism. It's a way of trying to improve your knowledge of nature, it's a system for testing your thoughts against the universe and seeing whether they match† Isaac Asimov 1988. Science is important because it can solve some of our problems such as global warming and world hunger. I believe that science is still evolving and there's trial and error with science which means we learn new information and we advance as humans but, it can all take years for such research or technology to be developed. â€Å"Technology can be thought of as the application of scientific knowledge for practical purposes†. I've always considered technology and science to be separate now, through critical analysis I know that science and technology are closely associated with each other. Which means technology is a part of science, it has been in existence since the prehistoric human culture (stone age). In my opinion technology is everywhere although we might not realise it our note books are a form of technology whereby we use our knowledge to document for practical purposes like computers. Overall for my first time doing this course it was challenging but, I've come to appreciate science and technology more, subsequently I can't imagine having to sleep without a roof above my head or having to cook using sticks and rocks. Through this experience I've got a spark of curiosity that makes me more enthusiastic to know more about science and technology. Scientists have reached so far in the field of technology whereby people can afford to do scientific research and make scientific break throughs from their own houses. The society we all know and accustomed to would be non-existent if it wasn't for the advancement in technology. We're so dependent on science and technology without realising it. 23 MORE WORDS Session Date: 29/01/18 Session No: 2 Session Title: Scientific Methods & The Nature of ScienceFor the second session, the lecturer started class with a recap of science. â€Å"All of science is uncertain and subject to revision. The glory of science is to imagine more than we could prove† Freeman Dyson. To follow up with the course outline, she started the second topic. To my understanding science is like a puzzle, to see the full image you need to put the pieces together. This can be distinguished through the scientific process. â€Å"The scientific method is a series of steps followed by scientific investigators to answer specific questions about the natural world† Regina Bailey 2017. What surprised me the most about this process is the fifth step experimentation, which is the most important step in this process. This is so because it can cause major breakthroughs in the world of science or a reversal. Through science we can make technological advancements and end some of the world major problems. â€Å"Fields of engineering are closely related to applied science. Applied science is important for technology development† Wikipedia 2018. It is understood that through scientific knowledge scientists have been able to provide services for the wellbeing of humans. Through many experiments people have been saying technology is good because it helps people medically and physically, it connects us as human beings and gives us entertainment. On the plus side technology is causing us to become less social. With this experiment, it shows how technology is applicated through private and public knowledge orientation. â€Å"Scientific objectivity is a characteristic of scientific claims, methods and results. It expresses the idea that the claims, methods and results of science are not, or should not be influenced by particular perspective value commitments, community bias or personal interests, to name a few relevant factors. Objectivity is often considered as an ideal for scientific inquiry, as a good reason for valuing scientific knowledge, and as the basis of the authority of science in society† Stanford Encyclopedia of philosophy 2014. To my knowledge there are three methods that scientists use inductive approach, deductive approach and hypothetico -deductive approach. The inductive approach and deductive approach are opposite, where the inductive approach is based off fact then there's a conclusion whilst deductive approach is a valid type of reasoning. Induction starts with observation, then a pattern, tentative, hypothesis and finally a theory. â€Å"In induction inference, we go from the specific to the general. We make many observations, discern a pattern, make a generalisation, and infer an explanation or a theory† Wassertheil Smoller 2017. Deduction has four stages theory, hypothesis, observation and confirmation. â€Å"Deductive reasoning is a logical process in which a conclusion is based on the concordance of multiple premises that are generally assumed to be true† Tech Target. Lastly hypothetico- deductive method which is seen as the only true method. What I understand is that the only way to truly test this is through experimentation which you either accept or reject the hypothesis and finally have an example. This week's session journal was manageable enough for me. Session Date: 05/02/18 Session No: 3 Session Title: Scientific Methods, Theories and ModelsIn this week's session, the lecturer started with the scientific method, then followed with theories and lastly models. Science is empirical, which means that it is based on observation over theory or logic. In class, we briefly discussed the history of scientific methods. It is understood that Plato 429-347 BC did not believe in empiricism but reasoning. â€Å"All knowledge could be obtained through pure reasoning (inductive), no need to actually go out and measure anything,† Plato 427-347 BC. â€Å"Contributions have been more influential, particularly when it comes to science and logical reasoning (deductive)† Aristotle 384-322 BC. Aristotle believed in empiricism. Personally, I agree with both Plato and Aristotle, for me science can be based on observation and reasoning also through empiricism where there's a logical way to test such observations. A major point in this week's session was observation. Observation is knowledge or data we acquire through experimentation. An example of observation from what I understand is the writing up of labs (biology or chemistry) for labs you have to observe then write what you understand. Through my research in observation I came across this question which intrigued me â€Å"Is creative concentration contagious?† Lynda Barry 2011. This brings me into another key example in topic three. When a baby sees his mother drinking in a cup, he tries to do the same with his cup, he holds it up and tries to take a sip from his cup. The baby first observes, then experiments. There are two types of observations, qualitative observations which uses your senses to observe the results and quantitative observations are made with instruments such as ruler, cylinders and thermometers which are tangible. These results are measurable. They could be used together or separately to measure data. Quantitative observation only gives statistical analysis after all the data has been gathered. What I understand from scientific theory is that it's a repetition of a process of the natural to ensure the accuracy or legitimacy using a form of observation and experiment. An example of this would be no new evidence would show water is wet, or that you can see without your glasses. Experimentation is the process of performing a scientific procedure, especially in a laboratory, to determine something† Oxford dictionaries 2018. From the information, I gathered from the session so far is that observation and experimentation are relate and there are two types of observation. â€Å"A statement based on repeated experimental observations that describes some aspects of the universe is called a scientific law' Wikipedia 2017. A scientific law doesn't explain the why or what of this observed phenomenon. The explanation of this phenomenon is the scientific theory, this is why or how they are related. â€Å"In science, laws are a starting place† Peter Coppinger 2017. The description of such phenomenon is called a model. These models can be physical, conceptual or mathematical it is often used in scientific theories.

Personal Computers Essay

Background. The Personal Computers at their advent were simple machines with less number of parts and limited capabilities. Less power was required to operate the computers and computer heating was never a major problem. However with the development in microprocessor and solid state technologies there was a revolution in how people used computers. The computers today can be configured according to ones needs and many add on components like graphics cards, Modems, USB devices etc. can be fitted on computers . Motherboards today also come with an increased number of components. However with the increase in components a new problem of heating has surfaced in computers. Problems and Motivation Although these components have increased the functionality of computers tremendously it has raised a serious problem of heating. With the increase in number of components the demand for power supply has increased. The components consume more energy and generate large amount heat. Electronic devices perform inefficiently or even get damaged as a result of excessive heat. Hence new challenges to protect these components from getting damaged by proper cooling of heat has emerged. Though the components have increased in numbers the size of PCs has kept reducing. People today prefer smaller PCs for space constraints and aesthetics. In order to keep in line with the reducing sizes the Power supply and the cooling system should also go transformation in sizes. One needs to design cooling systems with greater performances yet at a reduced scale. As the power supply and cooling are the components of PC case there is a need to renovate these cases to protect computer components from getting overheated and damaged. At the same time the it should be scaled down and match the aesthetics of other parts such as monitors, keyboards etc which come in designer shapes today. Research Aims and Objectives With reference to the above discussed problem there is a need to develop PC cases which are responsible for computer cooling. The aim of the project is to create simulation in order to find a better solution over the existing PC Cases and prevent spreading of heat to other components. The project will achieve three main objectives The initial objective would be to understand the principle of fluid dynamics and apply it to the PC Case problem. Secondly we will design a model to convert humid air by applying Computational Fluid Dynamics (CFD) The final objective would be to provide recommendations for the PC Case. Literature Review The preliminary literature was done on the existing problems in PC Cases and the sources of heat in computer system . The current methodologies implemented for cooling were also studied. Basic literature on application of fluid dynamics and use of Computational Fluid Dynamics to solve problems was also reviewed Methodology The Research will be experimental in nature. simulation model of the existing PC Cases will be developed in CFD. The models will be simulated again with modification for the proposed air cooling. The comparison between the two simulation will help in developing the cooling system and designing of the PC Cases. The results obtained will be experimental in nature and the problem is achievable theoretically with the help of CFD. As the project intends to suggest changes over the existing models the use of Simulation is justified to obtain outcomes as the existing systems are already simulated for cooling by making use of CFD. Triangulation: Mathematical models for the fluid dynamics of air can be constructed and solved for various conditions and the outcomes of these can be cross examined with the that of computer simulations. An experimental set-up can be created to check the prototype of cooling system and the results can be compared. Reliability : The prototype and the simulated models can be tested over a number of systems/components from different manufacturers and checked for reliability. Ethics: The project will adhere to all the guidelines and protocols of electronic manufacturing devices in terms of manufacturing, quality and safety. Environment : The proposed PC cases will be environment friendly. It may be manufactured from environmental friendly recycled materials to reducing global warming. Noise reduction will be achieved considerably with the improved change in design. Analysis The outcomes of the project will help in analyzing the reduction achieved in heat generated and the prevention of components. It will also analyze the cost of implementation and its economic feasibility. Conclusion With correct implementation of fluid dynamics modification in the existing PC cases can be achieved to cool heat efficiently and prevent components from overheating. Although the project is experimental in nature and relies mainly on simulation there may be a variation in its actual implementations. Whether the PC Cases behave as recommended can only be judged only by their practical application the project can be a strong foundation to extend this future scope.
