Coursework Example: The Sudan Countries Sign Agreement to Resume Oil Exports

enter image description here Southern Sudan disintegrated itself from the northern Sudan after having a civil war for a long time, a war that was considered to be the longest and costliest in Africa. South Sudan became independent in 2011, and one of the advantages it had over the northern Sudan is that it took almost three quarters of the revenue of the country, which is oil. The only advantage South Sudan had is that all the refinery, pipelines and port for organizing the exportation of the oil are in north Sudan. South Sudan stopped the oil production in the beginning of the year 2012, after having a dispute with the northern side over the transportation fee required. This almost led to both countries having a fight over the issue at around April, 2012 (Kushkush). The two countries have suffered a lot from the oil revenues loss, with the southern side, depending on it for approximately 98% of the revenues in the country. However, the two countries are taking a step forward to reduce the known hostilities that have made their economies weaken in a severe way. They decided to have the production and transportation of oil resumed, which saw them signing an agreement on Tuesday, 12th March 2013. According to the agreement signed, the resumption should begin in about two week’s time. The agreement read that they could resume to producing oil as soon as they are technically feasible. Stephen Dhieu Dau, the minister of petroleum and mining, said to the reporters that they hoped they could resume as soon as possible (Johnson 213). This agreement was signed in Addis Ababa, Ethiopia. It was under the African Union supervision. The agreement sets some mechanisms and a timetable that will be used in enacting a cooperation agreement that was signed by the two countries in September 2012. The agreement also contained other matters that were addressed in the agreement that are scheduled to be carried out immediately in the next couple of weeks. These matters include the borders demarcation, security arrangements, trade, pensions, economics and the status quo of the people, who live across the border. They also gave their consent to implement the agreement on March 10th, which the chief negotiator in Sudan, Idris Abdel-Gadir, when talking to the reporters, referred to this day as a D-Day. Before they made this agreement on Tuesday, the two countries defense ministers had made an agreement to establish a demilitarized area in the border line. This was meant to be a part of the security arrangements that they had both made (Lobban 104). This was done with an immediate effect as the defense minister in the northern part of Sudan, Abdel-Rahim Hussein, made confirmations to reporters that their troops had started moving away from the border. This withdrawal by the northern side made southern troops give orders to their troops in order to also make a step and withdraw from the agreed border zone as confirmed by the spokesman of the South Sudan troops, Philip Aguer. This agreement has been taken all over the world, with some countries having mixed feelings. The United States Department of State emphasizes that they have welcomed the signing of the agreement by saying that it would help in giving the two countries a safe border zone that will be demilitarized. However, the US fears that the agreement will not be implemented due to the two countries having a troubled history. The American ambassador, Susan E. Rice, claims that very few agreements are implemented despite them being signed. The agreement did not, however, make any agreement concerning the Abyei district, which has a lot of disputes (Human Rights Watch). However, they also agreed on establishing an administration, Security Council and a council in the region. The two sides have agreed to have another meeting again on Sunday, in the same venue. This agreement, which is a 17 page document that was signed by the Northern and Southern Sudan negotiators and facilitated by Thabo Mbeki, the former South African president, who is the African Union mediator, in terms of a timetable that is detailed so as to make implementations of several signed agreements. Oil will actually grab the headlines, but in actual fact, trades remain the most significant thing to the two countries citizens, who live near the border which is full of disputes (Copnall). The fact that this timetable was desperately needed is a clear indication of the difficulties that the two countries face. The two countries have experienced a lot of pressure, which is subjected to them by the international bodies and countries such as African Union, China, and the United States among others. Despite these pressures, the vital treaties agreed between the two countries have not been implemented. Conclusion This agreement cannot be considered as a new deal. It can be categorized best as a commitment that is made in order to make implementations of the previous nine agreements that were signed in September, 2012. One of the agreements made by the two countries last year was for them to set a buffer zone up. This was after the two Sudan countries had gone through their worst border clashes. That was back in April, after they had split. None of the agreements took effect. As the American ambassador, Susan E. Rice said that signing of agreements between the two countries is much easier than implementing them. This means that citizens of the two countries will have to wait and see the oil flowing, before they can start having any celebrations. The whole world is also waiting to see whether the agreement will be implemented due to the bad history that the two Sudan countries have.

Coursework Example: Political Sciences Islam Religion

enter image description here Religious Autocracy in Islam The Arab Spring is an event that is common and still fresh in every person’s mind as long as Islam and desire for democracy is concerned. What is of significance is that these strings of revolution occur in countries whose majority of residents are Muslims. Therefore, these incidences trigger a question whether democracy really existed or exists in countries that are Islamic. The Arab Spring is a terminology referring to standoff that world at large have witnessed between the ruling Islamic government and its supporters and the protesters. Since 2011, one Islamic country after another has undergone a revolution aimed at toppling the ruling government. The first country to go into a revolution and eventually succeed in removing its top leaders from office is the Republic of Tunisia. Zine El Abidine Ben Ali was the Tunisian president by then and blame game lied on his court where public accused him of poor democracy in his governance (Lutterbeck 32).Tunisia is a country whose governance outline is heavily inclined into Islamic teachings and principles. A larger percentage of the Tunisian mass felt that its president clinched onto power for so long, employed autocracy in his ruling, and barely cared about human right values. The president was the sole authoritarian, in which he hid his despicable ruling behind the shadow of the Holy Qur’an. However, the most startling thing in the Islamic teaching in the Holy Qur’an reiterates that neither authoritarian nor autocracy leadership is prioritized. Then, under which doctrines did this Tunisian leader base his authoritarian system of leadership? That is a question that many wonder about and put them into a dilemma since no one has a clear answer to it. However, the revolution had the responsibility of changing leadership where by Tunisia governance changed into a democratic one. The change raised a question whether Islam would be compatible with the democracy given that they have witnessed autocratic governance since time immemorial (Axiarlis 23). It is critical to accentuate that Islam as a culture and religion should be completely separated from politics. Indulging Islam into politics converts the religion making a tool that leaders can use in effort of achieving their political goals.

Events that took place in Tunisia did not end like that but acted as a precedent case for other Islamic countries that also felt that political change was fundamental for a better life. Egypt followed by toppling their president’s government, Hosni Mubarak, as they felt that he denied them their fundamental human rights. Hosni used authoritarian rule where he did not want to hand over power to another person despite being in leadership for over three decades. Libya was the third Islamic country to carry out a revolution against their leader, Muammar Gaddafi. Libyan also sighted similar reason behind this revolution that Muammar did not create room for human rights and constantly abused this fundamental right. Soon after, Gadaffi died of a bullet shot on his forehead and the rebels took charge of power. Libyans wanted a government that could listen to their grievances without any harassment or exertion of external pressures not to demand for their rights. Bahrain, Syria, and Yemen were other countries that went into a revolution demanding for democracy or self rule. This continuous chain of revolutions that have continued to bedevil Muslim world has created a debate in the world at large on whether there is a demand for democracy in the Muslim world. Since time immemorial, traditional autocracy system of governance and Islamic states were two things that remained inseparable. This developmental change raises some critical questions that seem a dilemma to many up to date. One of the critical questions is based on the current regimes of government that Muslim societies in plurality employ. The second question seeks to understand which regime of governance is preferred by the public living in Islamic States. Briefly, the two questions try to evaluate whether Muslim publics prefer secular democracies in place of traditional autocracy governance system. Secular democracy is a completely different phenomenon based on how Muslim publics are governed. Firstly, it gives room for freedom of worship where religious pluralism takes place freely, something that is illegal in many Islamic states since Islam is the sole state’s official religion. In secular democracy government authorities and religious ones are two autonomous entities. In Islam, the scenario is completely different as Islamic religion and state’s governance remain symbiotic. Any measure that the government intends to undertake must involve religious leader in effort of ensuring that it falls within the Islamic outline and principle. More often than not, many Islamic states practice religious suffocation where they do not allow religious beliefs diversification. Consequently, followers of other faiths such as Christianity and Buddhism find themselves placed at the corner of negligence and harassment (Tamimi 58).

Conversely, not all Islamic countries use traditional authoritarian leadership system since Turkey stands out unique. Despite more than 50% of Turkish population being Muslims, the country has fully embraced secular democracy as the outline of its governance. Turkey uses a system of governance that they popularly refer to as the Turkish Model. Here, the government of the day fully embraces secular democracy where every citizen has freedom of worship (Axiarlis 47). Religious pluralism is the order of the day when it comes to one’s freedom of worship. Any form of religion harassment is illegal and if accused of such an offence, one is apt of being fined or serving a jail term. Moreover, religion and the system of government function as two different bodies that are autonomous of each other. They only engage in during times of leadership consultation for a better Turkey. Therefore, this presumes that shari’ah law is not an arm of the Turkey’s government despite more than half of its population being Muslims. Malaysia is another country that has absorbed secular democracy just like Turkey and unlike Iran and Afghanistan, which have opted to remain under traditional authoritarian rule. In Iraq and Afghanistan, constitution of the country is based on the Islamic doctrines and guidelines. Therefore, this means there is prevalence of spiritual authorities in these countries’ governance and political system. Parties inclined to conservatives of Islam are the most predominant in these countries. Empowerment of religious courts is customary in the aim of ensuring that there is good adherence of Shari’ah laws by residents. The Afghanistan and Iranian model of governance mean that religious pluralism and also secular democracy has no place among their publics. However, there are other Islamic states that fall in between secular states and the traditional authoritarian rules. Therefore, these scenarios put forward a question whether secular democracy is indeed an essential tool in Islam or they view it as an obstruction to smooth running of their affairs.

Secular Democracy in Islam Democracy in Islam is a modern thought pertaining to Islamic politics. It is predominantly aimed at the effort of democratizing Islamic states which have for a long time been autocratic. In contrast, Muslim political scientists are keen on such a move given the fact that democracy is a Western ideology which if adopted can have enormous distortion on their lifestyle. However, there is another group of famous political think tanks who view it as beneficial to a democratic Islam. There were political scientists such as Mirza Mohhammad, Khomein, and al-Kawakibi and together they were of the idea of a practicable argument. Here, constitution could ensure that there was fundamental Islamic practices protection while at the same time establishing and maintaining democracy in a country’s governance (Sadri and Sadri 41). Mirza Mohammed’s idea faced opposition in that some fundamentalist thinkers saw Islam and democracy as two things that were totally incompatible. They cited that an irreconcilable rift existed between democratic principles and Islamic ones. There are a number of reasons that these fundamentalists based their arguments upon.

Firstly, they view democracy as a Western ideology aimed at distorting and diluting Islamic philosophies. There is also resistance to democratization of Islamic states based on the fact that western nations colonized them through a vile way. Therefore it becomes questionable reason for such countries to adopt it given the fact that Western oppressed them. Furthermore, its establishment grounds and the bad practices it creates make it undesirable for Muslims. Secular democracy is inseparable with bad vices in the society such as prostitution and homosexuality, practices that Islam condemns. However, these fundamentalists view the state of a government democratically while at the same time observing democracy as an absurdity. They are of the view that any democratic system of governance if construed in the right way may force them to sacrifice some Islamic values.

However, other intellectuals reiterate that incompatibility between Islam and democracy is a man made ideology. The complexity found here is as a result of Islamic teachings misinterpretation. They find no conflict as many Islam claims between the two sides. They consider it possible for Islamic nations attaining a religious democracy. However, they anticipated the journey to be long and tough due to stumbling blocks that do not only emanate from religion but also from the public’s cultures (Khan 87). What is highly critical is that there is need for constant renewing and also reviewing of the Islam and cultural beliefs. Consequently, feasibility of democratization of the Islam has given rise to conclusion or schools among politicians based in Muslim countries. There are four thoughts and these are:

  1. It is feasible to implement a democratic Islamic political system that will observe Islamic Shari’ah while unison having a harmonious society in an Islamic state. Public participation in making decision pertaining to politics can help in the allocation of socio-political aspirations relating to Islam. Moreover, democracy will help citizens portray their opinions since there is evenly distribution of political power (Chatterji and Jain 36).

  2. An endless conflict exists between the democracy and a traditional juridical referred to as fiqhi. Therefore, a religious democracy setup requires critical thinking. Additionally, it requires reviewing and also deep reinterpretation with an aim of realigning and conforming to the international values of democracy. Hence, the key to a religious democracy lies upon restructuring of Islamic knowledge that both political and religious leaders have kept traditional.

  3. Depiction of democracy as a disbelief (kufr) system that cannot in any case be compatible with Islamic doctrines and beliefs. Therefore, this phenomenon means that as long as one remains committed to Islamic teachings, he cannot leave any space for democracy.

  4. This school holds that state’s governance through a democratic Islam is an attainable scenario. The school accentuates that it is impossible for Islam to gratify foundations and values requires essential in democracy.

Power Concept in Islam In Islamic society, religious law possesses the right to justify a person attaining political powers. Therefore, the overall authoritarian in ranking system of power is the bench of jurist. Theologians established Islamic doctrines that relate to power enabling them to create a connection between theology and politics. They use a concept or philosophy referred to as classical Islamic. Pessimists in democracy already have a conclusion that a gap exists between cultural practices and religious ones. The gap is a result of differences in understanding of power legitimacy in the modern democracy and the Islam origin. On the contrary, democratic governance is completely opposite of the Islamic one since it only considers power legitimacy and its state without any religious affiliation. The concept sprung from Western world and it is popularly referred to as “Secular European Weberian Concept”. Western introduced this concept to the Islamic world during the 19th up to the 20th century during the colonial period (Khan 38). In addition, they also introduced another concept famously referred to as nation-state model.

The reason behind laxity in the adoption of secular democracy by Islamic states dates back hundreds of years back. Unlike democracy, theory of power in Islam is an indigenous phenomenon that a man known as Abu-al-Hasan developed during the 11th century. Abu al-Hasan was a jurist and also a scholar by then indicating how powerful religion was then. He based his opinion on belief that no one had the right to question a leader since he was an extension of the sacred law. Therefore, the state’s institution had to subject itself to the religious leadership. Islamic states prioritize on Islam doctrines and then narrow down to political social matters. Based on this framework, sacred Shari’ah entails the three arms of life which are social, juridical, and the political pillar. According to him, there existed no distinction that clearly portrayed a divide between the juridical and religious norms. Their origin could be traced from a single spot, which is from the prophet traditions, Sunna, and from the Qur’an. Based on this presupposition, therefore, one can carry out analyses as to why majorities of Islamic states have autocratic leaders.

Political leaders know that they have an obligation of safeguarding the sacred law and the divine will since they are subject to it. However, interpretation work of this law is a sole duty of jurists. However, at the formative stage of the Islamic civilization period, political and jurisprudence dominions became two different spheres. Religious scholars had consent to handle legal matters since they were well conversant with the Islamic doctrines. Jurists can command for approval of a political decision that a political leader enacts or disapproves if it goes against the Shari’ah law. Any establishment of legitimacy by a political leader, consequently, lied within the jury. Islamic jury tries to set laws that could help regulate both personal lives and the public sphere. Thus, political realm and the religious organ work cordially in trying to govern republic’s affairs.

Community’s Consensus in Islamic Countries Ijma is the perfect word referring to consensus in Arabic language. According to Islamic traditions, a ruler is equal to Allah’s tool where he has to observe the sacred law and become a mediator of the divine will. Authority to elect the ruler lies squarely within the community (Ummah). There is an assumption that the community is not subject to errors since God guides it through the divine authority process. Sunnah legitimizes the Ummah’s frailty since it treasures Mohammed the prophet’s words where he reiterated that that the community will not at any time accept an error (Meyer, Sahlin, Ventresca, and Walgenbach 59). For that reason, anything that the public agrees upon becomes legitimate. Hereditary succession in leadership is a phenomenon that is disallowed by traditions that guide the jury. Al-Ulama are a group of scholars that have the right to choose a new leader. Consultations (shura) are the process through which reaching of consensus takes place during a leader’s election. This body does not only embrace religious leaders but also entails social groups’ representatives. As a result, there must be balancing of power entrusted to rulers.

On the other hand, the study can be based on recent findings where there is close observation of Muslim states on whether they favor religious plurality or they are just religious autocracies. The study seeks to establish whether majority of these states opt to go for Turkish model that favors secular democracy or they are for religious autocracy model. Iranian government has absorbed religious autocracy model which tends to favor Islam over the other religions. However, according to findings of a recent research, countries depicting Muslim-plurality had positive attitudes in matters pertaining to democracy. Indeed, there existed no gap on the way Western publics and Muslim-pluralities viewed democracy. The two groups approved for democracy practices implementation, upheld ideals of it, and endorsed a system of political leadership. According to Mark Tussler, Egypt, Morocco, Algeria, and Jordan supported democracy in equal measures. Nonetheless, publics in Muslim states profoundly exhibit support for political and societal roles through authorities that are compared to Western publics in terms of religion. Indulging of religious leaders into matters of governing a country presented a problem due to the manner in which clergy view democracy. Clergy is not well conversant with democratic procedures in electing a leader since it entails electoral mechanisms and procedures. Clergy work in approving leaders is completely opposite to the democratic process since it involves processes such as inheritance and appointment. Therefore, democratization of most of the Islamic states exhibits tension since it would distort and dilute this society’s common understanding of leadership. However, countries such as Iran, Jordan, and Eritrea saw congruence between religious authorities and the democracy procedure despite them having little knowledge about democracy. Therefore, support for democracy or autocracy in these Islamic states depends on public’s attitude. Apparently, democratic support is one that is multidimensional and complex. Precisely, democratic governance without any consideration of trade-offs can prove it hard for one to determine relative preference of the rule that public wants. Consequently, Egyptians, Jordanians, and Moroccans exhibit great support when it comes to democratization of their countries. Nevertheless, this dilemma prevails when it comes to social stability maintenance, traditional authorities’ respect, or to the risk that relates to regime change. Correspondingly, when it comes to matters that relate to health sector positive rectification, then there is wide endorsement. However, when it comes to a trade off austerity measure such as taxation, there is validity in answers due options prioritization. Hence, this makes trade-off questions better tools for determining whether public of an Islamic state prefers autocratic governance or it is ready for democracy. In a nutshell, governance of Islamic states is not uniform but takes different forms which can be classified under the four categories of governance. These are secular democracy, religious autocracy, secular autocracy, and religious democracy. There is diversification in matters pertaining to regimes that govern Muslim-plurality publics. For instance, a country like Mali has a government that uses secular democracy despite having more 50 % of its population as Muslims. Chad is an Islamic country that uses secular autocracy system of government. Tunisia, on the other hand, has a system of governance that can be classified as religious autocracy. Therefore, one cannot make a conclusion that Muslim plurality governments use religious autocracy. However, it is a reality that majority of Islamic states use religious autocracy system to govern their internal affairs.

To sum up, when one takes a closer look at the Arab Spring that has rocked Islamic nations over the recent past, he will notice that there is a revolution for leadership change. Countries such Egypt managed to topple the Strongman Hosni Mubarrak, and Tunisia Ben Ali. There was no sparing of the Yemen leader, Ali Saleh Abdullah who was viewed as an autocratic leader. Other Islamic countries that experienced similar protests were Djibouti, Algeria, Jordan, Armenia, Iraq, Bahrain, Oman, Syria, and Libya. All of these states have similar complaints, they all demanded for democratic governance since their leaders were autocratic. The Islamic revolutions have drawn the world attention where there is focusing of eyes to North Africa and the Middle East. These revolutions have brought forth governance where the countries’ top leadership has given into public’s demand. Majority protested for democracy where they can be consented to live according to their wishes. As a result, these countries have gradually transformed to secular democracy from autocracy. Moreover, human rights observation activities have increased where there is freedom of worship. Ironically, other political analysts fear that religious extremist groups may attain power hence endorsing stricter Islamic laws than before. However, these revolutions offer a clear conclusion that majority of Muslim public wants secular democracy governance system as this was the main goal for the revolution. Therefore, it can be concluded that secular democracy governance system is completely incompatible with the Islamic teachings and religion. In fact, Qur’an can become a perfect tool that can help resolve the autocracy stalemate that has rocked Arab countries for long. Al- Ulama can make use of Shura (consultation) in their effort to engage with running of political affairs with their leaders (Safi 48). Consultation with secular and democratically elected leaders can be possible since the Holy Qur’an gives room for consultation with other groups. Moreover, human rights and religious pluralism is attainable since Qur’an grants everyone a chance to worship according to his will.

Coursework Example: Stress at Work

enter image description here Introduction Stress and any type of pressure at work are considered to be an integral part of people’s lives in today’s rapid flow of development. It can provide one with stimulus and energy; it makes a person challenge him or herself in order to assess his or her ability to deal with tough situations. Stress makes people uncover their hidden talents and make their own, sometimes risky decisions. Still, pressure is not always stimulating and helpful. Too much negative emotions can lead to loss of control and general perception of the situation. Stress at work is regarded as an extremely serious issue nowadays, because it affects both physical and mental well-being of the employee, and, consequently, has a considerable impact on the employer’s profit. For this reason, it is essential to define the concept of stress and be aware of its possible causes and effects. The Concept of Stress The Health and Safety Executive (HSE) Chris Rowe gives the following definition of stress, “the adverse reaction people have to excessive pressures or other types of demand placed on them” (Rowe 2009). It means that if someone has too many problems to tackle or lives or works in such conditions that prevent him or her from altering the situation, he or she is greatly exposed to stress, which will surely lead to serious outcomes and even more problems than a person has at the moment. As a rule, people manage to find out the solutions for their problems and resolve the situation without considerable losses and changes in their general state of body and mind. If they are really overwhelmed with pressures, stress defeats the pattern of evolution to come back to normal state after all these troubles that people had to overcome, and sets its own conditions, which are far away from normal. Stress at work is usually connected with the working environment, employee’s mental state, type of work, amount of tasks to do and many other factors. Depending on these factors, different kinds of stress exist. Kristin Koch (n.d.) defines the following eight types: 1) The worker always does something, he or she does not make any decisions, is “always on someone else’s schedule“. Koch names this type “overworked underling”. 2) The second type is “frustrated go-getter”. This person works as hard as he or she can, but does not get any promotion or at least compensation. 3) “Castaway” is someone who is absolutely ignored as if he or she is alone in the office. 4) “Doormat” has to deal with all customers even though they are demanding and abusive, and remain calm, professional and courteous. 5) For the fifth type, “tech person”, work has become his personal life as due to different gadgets, he or she can always be reached by the boss. 6) The “burnout” is utterly exhausted, because of working hours or amount of task. Koch (n.d.) says that people are physically and emotionally exhausted if they work in the emergency room, for instance. 7) “Bully target” is usually someone who is bullied by the boss or sees him or her bulling others. This person has to meet impossibly tight deadlines and is reprimanded in front of the staff. 8) The one who considers his or her work unfair is mistreated, and does arbitrary and unclear tasks, which can be called “wronged victim” (Koch n.d.). All in all, stress is a person’s reaction to the problems and pressures that he or she has to deal with. These and other factors influence the type of stress, among which Koch (n.d.) singles out “overworked underling”, “frustrated go-getter”, “castaway”, “doormat”, “tech person”, “burnout”, “bully target”, and “wronged victim”. Causes of Stress Different scientists provide diverse reasons for stress at work. If to follow the American Institute of Stress (n.d.), the main causes of this kind of stress are a combination of work and personal lives (20%), workload (46%), people issues (28%) and lack of job security (6%). Maxon (1999) suggests that employees of the factory, for example, are stressed because of working conditions, like having to cope with dangerous equipment or risking their health by inhaling chemicals and dust in the air. Office staff, on the contrary, is usually stressed due to relationships in the group. They are afraid to come into rivalry with colleagues or boss, be left alone without any possibility to get help or at least share the problem with someone. According to the report of the Health and Safety Executive Chris Rowe (2009), the state of the individual and the kind of relationships within the group are closely connected with six main factors – demands, level of control, management support, role, relationships and change. Although there are a lot of causes of stress at work, the main underlying ones, as HSE claims, are poor communication and insufficient training (Rowe 2009). Demands mean the amount of work the employee has to do. It is obvious that in order to be motivated and interested in what he or she does, the worker needs some challenge and pressure. If he or she is overloaded with the number of tasks to complete or the amount of information to process, the person becomes irritable, depressed and confused. Apparently, the greatest part of all employers try to ultimately control every process and every single worker, because he or she feels more confident and satisfied if everything is the way he or she wants. Clear rules, procedures and ways of conduct are important and often beneficial in the working process as they shorten the amount of questionable issues, but there are also drawbacks of this total control. The employees need to feel that they are able to control what they are doing, the way they do it and when they should finish it. If they are not allowed to take control any of these, workers are disaffected and alienated, and for that reason they do not perform well (Rowe 2009).

Support of the organization plays an important role in the way the employee feels and works. If he or she is provided with different benefits, this person feels confident, calm and sure of tomorrow. When one knows that he or she can talk to a manager in case of a problem or about anything that troubles him or her, then this person works as a part of the team, performs well and is less exposed to stress than the one who is left alone with the problematic issue. Rowe (2009) claims that if the worker does not feel free to talk to administration about the issue, he or she is more likely to be on the sick leave. Everyone would agree with the statement that if a person is in good relationships with boss and colleagues, he or she performs better and cannot be stressed about his or her life within a group. On the contrary, the one who feels alone or is bullied, ignored or mistreated cannot be satisfied with the situation and is more likely to quit or have problems with discipline. For that reason, managers and employers should be more aware of the situation in the staff and encourage cooperation. Role in the establishment is also important. One needs to know, what he or she is doing. The purpose of one’s work, his or her necessity and significance for the organization are topical as well. What is more, if the tasks are clear, there will not be any problems in accomplishing them, and an employee understands that he/ she performs well and for that reason is needed in the company. If the situation is completely different, the worker will be stressed about his role in the whole process. Change is often regarded as a positive fact as it usually brings flexibility, new opportunities and prosperity to the organization. However, very often employers do not care about the thorough preparation of the staff to possible alterations. It frequently happens that the employees get new equipment and are sufficiently trained, but there are people who need extra specifications, because their equipment or the type of work is a bit different and they feel perplexed. If they did not get explanation, they cannot do their job in a good way and get stressed. Effects of Work-Related Stress According to Maxon (1999), three quarters of all American employees are exposed to stress at work. United Nations’ International Labor Organization claimed that stress at work is a “global epidemic”. Brun (n.d.) provides the data, which backs up the claim about the global epidemic of stress. The statistics is astonishing: each year stress losses for the US enterprises cost $300 billion (Brun n.d.). Maxon (1999) says that stress costs in the USA make up to $200. Work-related stress usually results in staff turnover, absenteeism, workers’ compensation, lower productivity and other expenses for enterprises. Because of this Maxon (1999) suggests that “stress management may be business's most important challenge of the 21st century”. Consequently, the employers should consider every stress factor they can and try to prevent their workers from facing them. Stress brings troubles not only to the establishments, but to the workers first of all. It radically changes their well-being. Pressure and stress are reported to lead to heart attacks, strokes, different gastrointestinal problems like ulcer or gastritis. If a person lives in stressful conditions or works in a stressful environment, he or she is more likely to catch cold as his or her immune system gets weaker. Psychological effects of stress can be significant as well. Stress may end up in anxiety and depression; panic and anger attacks are also possible (Maxon 1999). All in all, stress at work is a serious issue that should be considered. Stress is a person’s reaction towards unhealthy environment, inappropriate treatment or any other factor. Considering these factors, scientists define different types of stress at work. For example, Koch (n.d.) indicates eight types. It is very important to be aware of the causes of stress and look for the ways to tackle it, because work-related stress influences both organization as it raises absenteeism, sick leaves, redundancy and low productivity rates, and employees, because stress can cause heart attacks, gastroenterological diseases and psychological disorders.

What Is a Coursework?

writing courseworkAll manuals and guides define a coursework as an academic task that helps to check and evaluate the student's knowledge in the certain discipline. Sometimes, a coursework paper is referred to as a report paper or course paper, but all these tasks have the same purpose. Certainly, this type is not as popular as the classic essay, but it is also a useful instrument to follow the student's progress. Coursework papers contribute to the student`s development in the certain discipline and teach him/her to be more responsible. Do not know what a coursework is? Follow our guide and get the writing motivation!

The essential difference between the classic essay and coursework is that the coursework involves much more research and, therefore, is longer than the essay. Writing a coursework, the student should present the clear evidence, reasonable arguments, and detailed analysis of the coursework topic. Also, unlike the essays, a coursework is focused mainly on checking the student`s practical skills. As such, the student should not put many theoretical data. If you experience certain difficulties with this academic task, feel free to address your professor with the question, “What is coursework” and he/she will explain you the peculiarities of this task.

A coursework project may be assigned within the scope of numerous disciplines and sometimes they may even look like the research papers. Searching for a good research paper example, the student may find many papers written on different topics online. Looking at these templates, you may check the structure, organization, and language, which can be truly helpful in writing your own paper. However, you should not take any information from these papers since, most probably, they were already submitted.

All in all, if you realize the importance of education for your personal growth then you should dedicate maximum attention to each of the academic tasks assigned by your professor. If you need to write a good report paper, you need to avoid procrastination. If you are planning to get a positive grade, you should start working on this assignment once the professor gives you the instruction. Also, you should gather the appropriate materials. Visit the library and select the relevant peer-reviewed sources, which can be helpful in the process of writing.

In conclusion, it should be mentioned that coursework writing belongs to the universal assignment, which can be written at any academic level. Indeed, this assignment can be truly fascinating since it allows to understand the assigned topic better and take a closer look at the subject. Constant practice in working on a coursework can make the student more motivated and curious, as well as improve his/her analytical and critical thinking skills, thus, stimulating the personal development.

What is a coursework? It is your chance to impress your professor with your responsible attitude to work as well as your brilliant writing and research skills!

Coursework Example: Effects of Online Sales of Consumer Goods

Economic Factors Enhancing Online Sales

Economic Effects of Online Sales of Consumer Goods to High Street Sellers Clothes

Various changes in economic market structure have enhanced the growth of online sales of consumer goods like clothes. The American government supports e- commerce because of various economic benefits that come with it. The internet covers a larger clothes market with various prices and this has made more people to shop online for clothes because of the wide variety. People have to leave the high streets because they have less variety compared to the online sellers.

Economic Factors Enhancing Online Sales

In addition, any sellers have also opted the online way because on the internet a wider customer base accesses their products. Another economic factor that has encouraged growth of online sales of clothes is the fact that the online market is very competitive and the sellers have reduced the prices to attract buyers. The retail shops at high streets have higher prices compared to the internet and this has encouraged more people to shop online for clothes. These factors have led to a situation where the high street sellers of clothes are competing with online sellers on price and non-price factors (Siddiqui, McColl & Birtwistle 2003, p.67).

Effects on Brick and Motar sellers in the High Streets

For many reasons like price convenience and time saving, people opt for online shopping of cloths. Online shopping offers better prices and as a result, it has attracted more people over time. Research shows that people between the age of 20 and 30 buy nearly half of their clothes online. It has had such a huge economic impact on the bricks and Motor sellers in the high streets. To stay relevant and competitive to the online market the bricks and motor sellers have to come up with strategies that will give them competitive advantage in the harsh global markets (Rajamma, Paswan & Ganesh 2007, p.154). The high streets sellers have to integrate their business with the online market so that even their products get accessed through the internet. Because of this, they must invest more in their businesses and avail their products online through websites. The sellers in the high streets have to renovate their shops in order to make them nicer and appealing to the customers. If the shop is appealing it lures the customer to get it. Customers are more tempted to enter shops that look nice because they assume they will find nice things. They have no option but to make the shops a nice place to visit. The sellers have to locate their shops in strategic places where they are easily accessible. The retail shops should not be in back streets and lanes. The bricks and motor sellers have to invest and make their stores bigger with more expensive, diversified and quality clothes in them. Despite having quality and attractive clothes, they should also have attractive price discounts, offers so that they can remain relevant, and counter the highly competitive online sellers (Torkzadeh & Dhillon 2002, p.139). Brick and motor sellers in the high streets have to do away with clothes that do not gain as much from selling in the physical store like nappies and pampers. The high street sellers now focus on expensive designs of clothes that will attract the customers to try out before buying. As a result, makes them incur extra costs such as seeking advice from sales assistants who are competent. They now have to have cool cloth products, which gets the attention of the customer without much hustle (Lee & Lin 2005, p. 79). The sellers have to create good relation with their customers so that they can win their loyalty. Many small scale Bricks and motor sellers are registering losses and some of the have closed down because they have been unable to keep up with the rapid online competition.

Coursework Example: Carbon Fibre Reinforced Polymers (CFRP)

CFRP - Carbone Fibre Reinforced Plastics


Carbon Fibre Reinforced Plastics (CFRP) also called DIALLED composite are materials that have been compressed by more 90 per cent of carbon fibres. Though expensive, they provide the highest mechanical properties, which are the strength and modulus of elasticity. CFRP is extremely strong and exhibits higher levels of rigidity than other matrix materials. They have low density intertwined level with excellent damping properties, high resistance to impacts, and thermal expansions that are exactly modifiable to supplement their complex features profile. The mix of these features make it a preference to other plastic materials like glass fibres and even such metals as iron and aluminium, in the manufacturing sector (Yao, Jacques & Norbert 2012, p. 15). For instance, in aerospace engineering, it is used for wings of the Airbus A350 and A310. In the automobile industry, it is used predominantly for the production of motor racing cars such as the Formula One bolides. Many companies use it in the manufacturing of motorcycle frames, manufacture of robot arms, sleeves and reinforcement in turbo molecular drive shafts and pumps. CFRP unique properties make it possible for the manufacturing companies to manipulate its content to suit the demands of different products with variations on the geometry and profile requirement. They include autoclave, fibre winding, pultrusion, matched-die moulding, reaction injection moulding, board pressing, integrated manufacturing systems, vacuum bagging, and manual lamination for personal and small-scale production. The discussion below gives detailed information on the properties of CFRP. It then links the properties to its tailored applications in the automobile industry and the reasons as to why it is gradually replacing the metallic components (Subic 2012, p. 71).

Advantages of the Carbon Fibre Reinforced Polymers

The carbon fibre reinforced polymer has high stiffness capabilities and is lightweight. For its weight, it is the strongest and stiffest material. It is outperforming other materials including timber, steel, and aluminium. It has approximately quarter-space gravity of iron and two thirds of aluminium making it stiffer and stronger than iron. It has high attenuation of vibration possible and high impact strength. It means that the material does not change shape even if someone ruptures it. Therefore, CFRP is suitable for low bending, high-speed operations, space saving, and activities that require suppression of vibrations (Durand 2008, p. 60). DIALLED composite has the highest thermal conductivity. It is the only existing plastic material that has thermal conductivity equivalent to copper. It realizes higher thermal conductivity than usual plastic materials. This feature makes CFRP suitable for lightweight heat sink, incombustibility, and performance at extremely high temperature. In addition, CFRP has a low coefficient of thermal expansion. This feature explains its excellent performance in thermal dimensional stability. It allows making the coefficient of thermal expansion to zero by the composite design. Therefore, it is perfect for situations that have high levels of temperature fluctuations such as in automobiles (Deng 2008, p. 18). DIALLED composite has also an approximation of over 95 per cent reduction in components by combining forms and parts into simpler moulded-parts. Overall, it shows a reduction in the cost of production. These materials are also light allowing economy on parts and low operational costs. Moreover, the reduction in weight of the components of CFRP leads to low fuel consumption (Yao, Jacques & Norbert 2012, p. 15). CFRP is resistant to chemicals because it has low reactive capabilities. This feature makes it ideal as a protective covering for surfaces with spillages of chemicals that are fit for the automobile industry. In addition, CFRP is corrosion resistance. Therefore, automobile industries prefer it to other metals because the vehicle would last longer with the least maintenance. Companies may enhance the duration, for which their cars are likely to last by customizing its colours. It is possible for the manufacturers to add little chemicals to DIALLED composites and protect their cars against ultraviolet rays. In addition, CFRP materials are poor conductors of electricity (unless the manufacturers modifies it to conduct electricity), and anti-magnetic making it possible for the automobile industry to use it as an insulator. It could also be fire resistant if the producers incorporate some additives (Deng 2008, p. 26).

Processing Characteristics of the CFRP and High Production Rates of the Automobile Companies

The consumption of carbon fibre reinforced polymers stood at only 5 per cent of all the world production in 2012 and projected to clock 30 per cent by 2020 (Ekiz 2007, p. 12). The dismal usage of CFRP is associated with the incapacitation of companies to process the product in large quantities. The whole process of tailoring carbon into forms that automobile manufacturing companies can consume is a lengthy one. The pace, at which companies produce these CFRP, is sluggish and not capable of supplying the production chain of automobiles with the required input amount. In addition, the process also requires the company to invest a lot in technology for it to make various car components from these CFRP raw materials (Carnay 2011, p.1). Because of this fact, the demand for the product that has created an artificial shortage has been high. In response to the market demands, the prices of DIALLED composite materials have gone up. It means that the manufacturers have to find better ways of covering up for these losses making some of them shift back to the use of aluminium in their production of cars (Ekiz 2007, p. 12).

Decline in the Use of Carbon Fibre Reinforced Polymers in the Automobile Industry

There is always artificial shortage in the production of CFRP leading to high prices of CFRP making companies resort to aluminium as demonstrated above. The reason for preference of Aluminium in productions of automobile is that it does not need the long processes, through which the companies using CFRP must systematically go. Consequently, the use of aluminium in car production saves time. Other than the long process that wastes time, the company would be compelled to hire more labourers since the use of CFRP requires much work force (Carnay 2011, p.1). Carnay (2011, p.1) notes that, in the short-run, CFRP saves money by using CFRP. However, the savings are ploughed back to the production cost in the form of buying expensive raw materials, compensation for time lost, and hiring more labour force. For this reason, many companies are shifting back to the use of aluminium in their production of automobiles. He warns that, not unless the intense labour use, and high rate of technology in the productions of CFRP is reverted, the use of DIALLED composites in the production of cars may be abandoned (Carnay 2011, p.1). Aluminium has immensely contributed to the decline of the CFRP use in the automobile industry. Firstly, aluminium is readily available and has a very straightforward production process making it possible to produce it in large scale. Therefore, the companies that produce big volumes of cars can use aluminium conveniently unlike CFRP. Secondly, it is easier to process and tailor the aluminium materials to different car components and then join the parts together. Thirdly, there are five different types of the aluminium alloys with various properties suited for a particular function within the car. Fourthly, the improvement of technology on the use of aluminium has also made it better for manufacturers of cars. For example, heat-treating using aluminium enhances deformability properties of the car to absorb crash and reduce damage. Moreover, firms can tailor it into different shapes more easily and at lower temperatures than CRFP. Manufacturers will soon be joining parts using the cheap technology of bonding since there are plans to use epoxy joining and reducing the weight of aluminium (Carney 2011, p. 1).

College Coursework Sample: Electronic Communication

college coursework sample electronic communication

Various threats face electrical contact. These threats may be technical, financial, physical and, cost. One of the most common risks of electrical communication is the power failure, which sometimes leads to equipment failure. Accidents are also a threat to electrical contact. The transmission lines in case of data transfer by the electrical wire may be destroyed through accident. For example, the pole holding up contact wire may be hit by a car. This leads the termination of the information signal in the transmission line.

This can be prevented by using stronger post that cannot be easily knocked down by cars. Natural disasters are a threat to the electrical connection this is because when they occur. The electrical communication systems get destroyed. For instance, when earthquake happens they tear up communication infrastructure. This completely disables the electrical communication system. This can be avoided by building communication infrastructure that can withstand earthquake shock. Malicious people can do deliberate physical attack.

The attack may disable the electrical communication devices attacked. Human error is also a threat to communication system. In fact, most of the electrical communication failures are caused by human error. Human error can be avoided by user being keen and attentive when handling the communication devices.

Data tampering when is in transit is one of the major threats of electronic communication. A malevolent third party can tampers with the data during transit. Example of data attack in transit is altering the amount of money transfer electronically from one bank account to another, i.e. changing $2000 to $ 20000. This attack can be prevented by interjecting whole set of a valid transfer into the network. This can be done by repeating an adequate $2000 money transfer a thousand times. Eavesdropping; it is secretly listening conversation without the communicating parties consent. For instance, in local area network (LAN) insiders hardwired to the network can access information that is they do not have clearance for. Also, network sniffers are installed on network traffic to eavesdropping (Albert, A. L. 1934).

Falsifying User Identities; all the users in the system must be known, to prevent falsifying user identities. Distributed network is prone to user identity falsification, which may lead to an unknown user accessing sensitive information. Individuals in electronic communication are facing identity theft. Internet hackers are stealing driver’s license numbers and credit card numbers. Criminals use this information to set up fake credit account using a stolen identity Moreover; non- repudiation is threat to identity. Criminals steal someone’s digital signature and use it to do illegal activities. The owners of the signing key can be held responsible for the illegal activities (Lin, X. 2008).

Password-related threats, in gigantic systems, the system user is required to memorize multiple passwords for the various application and services they use. For instance, a user can access several computers to on a workstation for testing and managing configurations of a development application and a personal computer for checking email. To remember the password they may use a word found in the dictionary. Dictionary attack can crack this password. The user with complex passwords may write them down on a piece of paper. If the paper fall on an attacker hands, the communication system is compromised. Lack of accountability can occur in electrical communication systems. This is seen when the system administrator cannot monitor all user’s activities in the system. Thus, the user are cannot be accountable for their activities.

Sophisticated user management requirements are a considerable threat to electrical communication; network may have complicated user management requirements. Any communication system must support several hundreds of users. Therefore, the system must be scalable. Due to the system large size managing password and accounts becomes hard which makes the system prone to attacks and error. To have a reliable security all the users in the system must be identified.

Some of the recommendation to the electrical communication technologies providers on how to protect their information transmission systems is. Providing users wireless data transmission with robust encryption. Secondly, the radio network has to be designed to cope with automated failover and redundancy. The communication systems towers must have lightning arrestors. In addition, the electrical communication system makes use of overlapping coverage, in addition to it can pose fallback and lessen operation modes if equipment failure occurs. The modern communications managing systems are now capable of promptly identifying when the equipment fails, thus immediately sending an alarm to the concerned party. Besides, a lot of them utilize full substantial sensors for tracking humidity, as well as temperatures. The electrical communication devices that are handled are rugged. Thus, they can withstand impact, properly work under external temperatures, and be smoke resistance and water proof (Lin, X. 2008).

The regulatory body guide engineer on how to effectively deal with development mythologies. For instance, encryption algorithms and methodologies are incorporated in the association of public safety communication officers (APCO) project 25 and Terrestrial Trunked Radio (TETRA) standards for digital radio systems, and several vendor supply cryptographic implementation that are certified as compliant National Institute of Standards, Federal Information Processing Standards FIPS-140-1 as well.(Voice radio communications guide for the fire service manual: a basic guide to system concepts and equipment. 2008).

Coursework: Overall equipment effectiveness (OEE)

Overall equipment effectiveness

Manufacturing a product is a difficult practice. Due to lack of metrics and plans, it is quite easy to lose direction and have the industry managed by the production. Overall equipment effectiveness (OEE) is a criterion that combines various manufacturing issues and figures to provide information concerning the progression. Through a predictable process of combining the essential data, OEE gives definite process information. All staff members can utilize the facts to comprehend the modern shape of the manufacturing process. By having a programed structure of the impact of machine accessibility, performance, and eminence, OEE provides an outline to trace fundamental issues and their origins. Moreover, OEE provides a structure for improvements in the manufacturing process (Mohammadi & Mehta 2011). This paper calculates the availability, performance, quality, and OEE of the company that manufactures radiators and heat exchangers. In addition, it will analyze losses using Pareto technique giving recommendations for improvements.

Question One

OEE takes into consideration three factors: availability, performance, and quality (Reyes 2010). It is calculated using the following formula:

OEE = Availability x Performance x Quality, where availability is the machine used for planned manufacture.

At the most crucial point of the process operation, worth for the ultimate user is created. When a process stops, it creates an expenditure with no linked charge. It can be explained by mechanical failure, operator issues, raw materials, and machine operation. Comparing planned run time to actual run time, the availability constituent of OEE allows to calculate the lost production due to downtime (Mohammadi & Mehta 2011).

Performance is calculated by the amount of waste produced through operation at less than most favorable speed. By comparing the real cycle time and perfect cycle time, it is possible to calculate the amount of production lost through cycles that did not attract the perfect cycle time (Reyes 2010). On the other hand, quality focuses on determining the time spent on production of a good that does not meet quality requirements. Through comparison of the amount of good to reject parts, the percent of the time truly adding value by producing a good product is exposed (Stamatis 2010).

Using the TD tube machine data, one can derive the following:

OEE = Availability * Performance * Quality

Availability = planned run-time – down-time/planned run-time

Planned run-time is 8 hours or 480 minutes (from 8 am to 4 pm, there are 8 hours multiplied by 60 minutes) per day from Monday to Friday.

Down time = minor stops + startup losses + breakdowns + reel changes + materials + breaks + set ups

Monday down time = 5 + 40 + 51 + 25 + 45 + 18 + 26 = 210

Tuesday down time = 5 + 66 + 21 + 40 + 20 +32 = 184

Wednesday down time = 60 + 29 + 50 + 14 + 19 = 172

Thursday down time = 1 + 48 + 16 + 30 + 20 + 29 = 14

Friday down time = 1 + 70 + 19 + 75 + 14 + 39 = 218

Good lengths = total lengths – rejected/bad lengths.

Monday total lengths = 1347 + 1283 + 1588 + 1588 + 1283 = 7089.

Monday bad lengths = 25 + 24 + 10 + 25 + 5 + 4 = 93

Tuesday total lengths = 1283 + 1588 + 1347 = 4218.

Tuesday bad lengths = 5+15+9+4+6+40+6+8 = 93

Wednesday total lengths = 1347=1588 = 2935.

Wednesday bad lengths = 35+20+10+6+22+10+15+20+6+15+20+10+6+25+15 = 235

Thursday total length = 1347+1941+1283+1347 = 5918.

Thursday bad lengths = 6+10+6+10+6+6+6+8+29 = 87

Friday total lengths = 1347+1588 = 2935.

Friday bad lengths = 40+15+6+6+12+6+10+6+6 = 107

Total lengths for the week = 7089+4218+2935+5918+2935 = 23095.

Total week’s bad lengths = 93+93+235+87+107 = 615

Good length = total lengths – bad lengths = 23095 – 615 = 22480

Therefore, daily availability of the company is the following:

Day planned run-time (A) Down-time (B) availability (A-B/A*100)
Monday 480 minutes 210 minutes 56.25%
Tuesday 480 minutes 184 minutes 61.67%
Wednesday 480 minutes 172 minutes 64.17%
Thursday 480 minutes 144 minutes 70%
Friday 480 minutes 218 minutes 54.58%

Performance = (Total length / Operating Time) / Ideal Run Rate; where operating time is equal to planned run time minus down time (A-B) (Koch, Oskam & Neve 2007). There is an assumption that the values in brackets for real changes in the provided data represent the ideal run rate. Therefore, daily performance is the following:

Day Total Lengths Operating Time Ideal Run Rate Performance
Monday 7089 270 minutes 9 length/minute 2.9172
Tuesday 4218 296 minutes 11 length/minute 1.2955
Wednesday 2935 308 minutes 9 length/minute 1.0588
Thursday 5918 336 minutes 8 length/minute 2.2016
Friday 2935 262 minutes 12 length/minute 0.9335

Quality is given by: Quality = good lengths/total lengths

Day Good Lengths (A) Total Lengths (B) Quality (A/B*100)
Monday 6996 7089 98.69%
Tuesday 4125 4218 97.80%
Wednesday 2700 2935 91.99%
Thursday 5831 5918 98.53%
Friday 2828 2935 96.35%

Note: good lengths are given by total length – bad length.

OEE = Availability * Performance * Quality

Day Availability (A) Performance (P) Quality (Q) OEE (A*P*Q)
Monday 56.25% 291.72% 98.69% 161.94%
Tuesday 61.67% 129.55% 97.80% 78.14%
Wednesday 64.17% 105.88% 91.99% 62.50%
Thursday 70% 220.16% 98.53% 151.85%
Friday 54.58% 93.95% 96.35% 49.41%

From the calculations, it is evident that OEE is not the exact objective; however, it provides the three variables. A company may have low availability, but its effectiveness is outstanding. From the rates of Monday and Tuesday, it is clear that the availability on Monday is lower than that on Tuesday, while Monday's OEE is still higher.

Question Two

Pareto analysis is a straightforward system for prioritizing probable changes by identifying the problems that will be determined by these alterations (Suzuki 2009). By using this method, one can prioritize the single changes that will influence the condition. The study applies the Pareto theory also identified as the "80/20 Rule," which states that 20 percent of causes produce 80 percent of outcomes (Parmenter 2007). This instrument will help to discover the 20 percent of effort that will engender 80 percent of the outcomes caused by responsibility.

The use of Pareto analysis involves following steps. First, classification and recording problems and their causes. Second, scoring every setback and clustering them collectively by their cause. Third, summing up the score for each cluster. Finally, finding an answer to the cause of the problems in cluster bearing the uppermost score (Parmenter 2007). TD machine factory Pareto analysis for the losses would be:

# Problem (Step 1) Cause (Step 2) Score (Step 3)
1 Bad cutting finish on tube knives changed 18
2 Bad finish on dross out solder changed flux set up machine for thin 19.5
3 M/C down bad finish on the tube removed and cleaned knives 7.2
4 Marks on tube pick up on tinned brass 15
5 Lost time during set-up greased rollers 17

Clustering of the cause together and scoring them according to the amount of loss:

Knives removed (causes 1 and 3) = 25.2

Changed flux set up machine for thin (cause 2 and 4) = 34.5

Greased rollers = 17

Pareto Analysis of Loss

Graph 1. Pareto Analysis of Loss

The Pareto analysis and bar graph above show that the company may achieve great profits and avoid many losses by capitalizing on changing machine setup for thin. Once the cause minimizes, it will be worth observing quality cuts of the tube that is advantageous to the company.

Coursework: Carbon Fibre Reinforced Polymers

Coursework Example: Carbon Fibre Reinforced Polymers


This paper answers two different questions with regards to carbon fibre reinforced polymers. The first question discusses the advantages of carbon fibre reinforced polymers with respect to their mechanical & specific properties in replacing traditional metallics in vehicle body structural applications. In the second question, the paper addresses how high production rates required for many standard classes of vehicles correspond to use of such composite materials. It is done with respect to their processing characteristics. This is important considering that such materials are supplied in the form of pre-preg that must be vacuum bagged and autoclave moulded

Question 1a

Recent proliferation in the use of plastics reinforcement with carbon fibre in load bearing structures of automobiles is a great way to reducing fuel consumption and the weight of the vehicle. Carbon fibre reinforced polymers are not widely used as metals but their use is becoming popular with many manufacturers. The materials have found a wide range of applications in not just the automobiles but also in construction and aerospace. It is majorly due to their specific stiffness and strength, as well as lightness in weight. Carbon fibres also have the other advantages that make their use preferable in automobiles. The materials have a tensile strength, which is six times greater than metals. Such property is important in structures that are exposed to excessive force in the automobiles. Carbon fibre reinforced structures have improved tensional stiffness and high impact properties that make them function better in areas of high impact in a vehicle. In addition, the material has a higher rate of up to 60% of the ultimate tensile strength and it allows the polymers to endure fatigue (Ghassemieh, 2012).

CRFPs also have lower embedded energy when compared to metals. Such property is essential especially where the energy from the automobile engine is absorbed by the metal reducing its force and momentum. The low energy embedded is also important in hot weather conditions where metallic automobile uses air conditions to cool the inside of the automobile. CRFPs are also less noisy during operation and have lower vibration transmission when compared to metals. It is difficult to design metals into some shapes. It may take some time to be achieved and is also very expensive. CRFPs are easier to design into different shapes in relation to the needs and complexity of the design. The materials are more versatile, thus allowing easier, less expensive and faster design into different shapes. Compared to metals, CFRPs are more durable as they have a lower rate of wear and tear compared to metals. They also demonstrate excellent impact and environmental resistance. Thus, the materials are less expensive to maintain (Elmarakbi, 2013).

The anisotropic nature of carbon fibre reinforced polymers is a property that can cause a decreasing of fatigue endurance level of these materials. The anisotropic conductivity of these polymers also affects the unidirectional conductivity of the materials that is a part of the important specific property. To reduce the effect of anisotropy, the designer can exploit the electromagnetic behaviour of the polymer to enhance the automobile performance in highly fatigued areas. The unidirectional carbon fibre reinforced polymers when laminated can act as conductors in parallel E-field and dielectric in perpendicular E-field. Such understanding should help the designer of the material come up with carbon reinforced polymers that meet the fatigue rate of the automobile (Kelly, 2004).

Question 1b

Composite materials are not yet widely used in the automobile industry. However, there are many opportunities where advanced composites can be put into commercial use in automobile. For instance, in specialty vehicles that require small quantity of composite materials, they are already used to demonstrate the capabilities of CFRP. The composite industry is investing in coming up with improved processing that includes moulding of the plastics through conventional E-glass and mid-level performance resins. The thermoset and thermoplastic automobiles account for 50% composite market. The relatively low cost of fibre and faster cycle time will ensure easier integration. CFRP can be processed in different methods, including desizing and etching in the prepreg conditions. Open mold approach can be used to prepare the composite samples before the application of fibre and resins on the material. The designer can then fix the carbon fibres in a unidirectional arrangement so that to keep parallel fibres in a state of tension (Mallick, 2007). The processing of prepreg composites is undertaken in consideration of the required volumes. It is among the impediments to the widespread adoption of composites in the automobile industry especially where mass production is needed. The cost of the raw material and lack of suitable manufacturing processes impedes on the use of that material in the production of automobiles. The production engineers are left with the responsibility of making a choice in relation to the required rate of production, if they are going to use CFRP. An average truck within a manufacturing plant will require up to 20,000 units per year, which makes their handling another task. For small cars, the figure is even higher in the ranges of 500,000 units. In addition, CFRP in prepreg conditions are subject to the other conditions, such as scrap production, cycle time and tooling costs that many automobile producers might not be willing to meet (McWilliams, 2007).

The tools used in the composite production are cheaper when compared to those used in metal forming due to single moulding in CFRP. On the other hand, metals require five to six different tools in single component line. However, such simple saving in tool costs can only be realised at low production volumes in CFRP processing but not in higher volumes that require a part of dominance. The processing of CFRP at low volumes can only be maximized in short fibre reinforced thermoplastic injection and also in bulk processing processes (Elmarakbi, 2013). However, it has not been found to be applicable in structural building, not to mention automobile building. The development of long fibre reinforced thermoplastic will bring CFRP closer to a structural fibre. The injection moulding is advantageous as it has short cycle time and produces little scrap. Very few processes are available for medium composite material processing, including the sheet and compression moulding. They have also been automated and used in vehicles with cycle times ranging a span of few minutes (Kelly, 2004).

Question 2

The carbon fibre reinforced polymers have been touted as the answer to the issue of weight and strength in automobile manufacturing. However, in the recent past niche vehicle manufactures have been moving away from CFRP due to the counter elements that make their use of CFRP not only improbable but also costly. The use of CFRP is not so much hinged on automated processes as its competing aluminium material. The low volume production and high priced vehicles mean that using hand-built tools to build them will increase tremendously the cost of production. It will push further the prices of the car. It might not be good for customers of such specialized cars (Society of Automotive Engineers, 2014).

Labour and time considerations are essential factors in the use of CFRP materials in niche vehicle productions as it impacts the production speed. The process also impedes on the advantage of weight-saving potential as soon as high volume construction technique is used. As such, the use of CFRP materials in low volume and niche production of vehicles is rather a factor of the unavailability of the necessary technology and labour than the advantage of the other materials. It implies that a better technology in the future might experience the coming back of composite materials in production of niche vehicles (McWilliams, 2007).

Low volume specialized cars also have special characteristics that cannot be delivered through the use of CFRP material in the production. For instance, the heat-treatment technology that uses aluminium improves the vehicle’s deformability properties and improves its crash absorption, which is something that still appeals to the consumers of such products. Aluminium is also able to deliver similar advantages, such as low weight and better control of inertia, hence better handling by the user among the other benefits.

Statistics, Health Effects, and Advantages of Pets

Pets play a very important role in human beings’ lives. They are domesticated animals for a variety of reasons. Pet ownership statistics has been changing over time.

Nowadays, the number of pet owners is continually increasing and more pets are bred with desirable characteristics that meet the demands of the pet market. According to pet ownership statistics published by Insurance Information Institute, 68 percent of all the households in the United States of America now own a pet.

The research that led to this finding is called the National Pet Owners Survey conducted by American Pet Products Association in the year 2017. A similar research was first carried out in the year 1988 and had indicated that 56 percent of the total United States households owned pets (Insurance Information Institute, 2017). In a span of about thirty years, the pet ownership statistics showed that there has been an increase in the number of households owning pets by about 12 percent. People have always loved pets, and this trend is rising with the relative increase in households.

There are many benefits of having a pet. They are very great friends to their human owners. Pets show unconditional love to their masters and thus provide them with emotional boost. Pets reduce stress, depression, anxiety and lower the risks of stroke and heart attack in their owners. According to a study conducted in the year 2002 at the State University of New York at Buffalo, people experienced less stress when conducting stressful tasks with their pets around them than when their spouses, family or close friends were nearby (Gekas, 2011).

As a result of the numerous benefits of having a pet, many families have acquired the family pet. The family pet serves the needs of the whole family and most families prefer good small pets that can be easily handled and fed without strain. Some of the good small family pets include cats, dogs, small reptiles like snakes, and birds.

Health Benefits of Owning a Dog

According to the National Pet Owners Survey of 2017, the most owned pet is dog as more than 60.2 million dogs are owned by the United States households only (Insurance Information Institute, 2017). In most of these households, kids are found to spend most of their time with the dog pets.

However, there are some breeds of dogs that are good with kids while others are not. Dogs that are good with kids include the Golden retriever, the Labrador retriever, the Poodle, the Vizsla, the Irish setter, the Bulldog, the Collie, the Beagle, the Newfoundland and the Bull terrier. These dogs possess characteristics that make them good for kids.

They have infinite patience, natural ability to protect children when needed, and others can play endlessly with kids (PETMD, 2017). As a result, having sucg a dog gives kids numerous benefits. These advantages include learning key life skills of being responsible and cooperative. The dogs also show the kids their unconditional love which is important especially in busy families where parents are absent most of the time. However, some questions like “Can humans get worms from dogs?” remain paramount. Dogs that are infected with roundworms may easily infect their owners if they ingest the dog’s fecal matter knowingly or unknowingly.

Health Benefits of Owning a Cat

Cats are the second most owned pets after dogs according to the National Pet Owners Survey of 2017, with 47.1 million cats kept in the United States households (Insurance Information Institute, 2017). There are many benefits of owning a cat like increased immunity from the exposure to the cat fur and better resistance to allergens, decreased risk of heart attacks due to the emotional boost caused by cat pets.

Low blood pressure in cat pet owners is a result of the calming effect cats have and reduced anxiety and stress are explained by the soothing nature of cats (Health Fitness Revolution, 2015). The questions that many cat pet owners ask themselves is “Can humans get worms from cats?” and “Can you catch a cold from a cat?” According to Jessica Gomez, a vet technician, humans can get worms from the infected cats.

Human beings can contract round worms and hookworms from cats when they ingest eggs of the worms from the cat’s fecal matter. Human beings cannot, however, catch a cold from a cat. This is because the cold causative agents for humans and cats are quite different. Cold causative agent in humans is the bacteria called Chlamydia trachomatis while the cold causative agent in cats is called Chlamydia psittaci. The two cause cold to their respective hosts only (2017).

Best Pet for Kids

The best pets for kids should possess certain characteristics. To be more precise, they should be calm, courageous, friendly, loving, lovable, happy, easygoing, patient, and companionable. They should also have an agreeable temperament, small excitable size and a lot of energy that cannot drain that of the kid. Among the many breeds of dogs, there are breeds that suit exactly kids’ needs. The good dog breeds for kids include the Beagle, Golden retriever, Collie, Poodle, Irish setter, Labrador retriever, Newfoundland, Bull Terrie and the Vizsla.

Similarly. Good cat breeds for kids must meet the above characteristics, and they include the Abyssinian, Maine coon, Burmese, Ragdoll, Manx, and the Persian. For the reptile enthusiast, the best pets include the anole - a colorful neck lizard with a lifespan longer than 5 years, the bearded dragon lizard - a gentle lizard that enjoys being picked up, the Leopard gecko – a calm and easy to handle lizard, and some snakes that can be treated to be wonderfully docile and manageable with a lifespan of up to 35 years. The tortoise, turtle, and the water dragon are other reptiles that can be easily reared as pets.
