Model of Leadership Essay -- Leadership, philosophy

A large amount of work has gone into studying, researching, and developing stupefys of leadership. in that location have been numerous models put forth, examined, applied, and either used or discarded. However, after all this work, there is still not one perfect model or method acting of leading. Every situation and assemblage is dissimilar, therefore a good leader must be flexible. A good model of leadership is one that incorporates different models into one that understands that the only constant is change. Therefore, my model of leadership will be based primarily upon flexibility. I feel that a leader must stolon understand the basic styles of leadership and how to apply them. Then he/she can know what style is the roughly appropriate given the task and group composition. Second, he/she must be able to observe his/her group in order to decide when the aforementioned styles are to be applied, and when problems lay out threatening the group or its task. Then, that leader mus t be able to effectively communicate and influence his/her followers in order to fix problems, provide feedback, and inspire a group to be more than the sum of its parts. That is what effective leadership is about. Whatever is flexible and flowing will tend to grow. Whatever is rigid and blocked will shrivel and die.-John Heider, The Tao of Leadership A flexible leader realizes the advantages and disadvantages inherent in each of the three styles of Authoritarian, Democratic, and Laissez-faire leadership. While it seems that most of the researchers agree that democratic style is the most effective, there are certain situations that call for different styles. Effective leadership demands that a leader be able to adjust his/her style according to the circumstances. Autho... ...th sexual love than with vinegar. It is my hope that I have developed a competent model of leadership arising out of flexibility. I hope that I can apply this model in my own practices of leadership, to help me build the confidence I need to grow out of my leadership apprehension. I feel that an understanding of the group process, and of the styles of leadership, working together, can provide one with a very powerful method of effective, flexible leadership that can be applied to multiple groups and situations. First, by larn the styles of leadership, he makes harmony between himself and the group. When understands how the group acts and reacts, he can make harmony between the members of the group. And when this leader understands how to influence and conduct his followers, they can both begin to play beautiful music that no one would have been able to play alone.

Ethnic Cleansing in Kosovo What Happened Before and After NATO Interven

What Happened Before and After NATO Intervened in KosovoImagine waking up one day to the thundering of blows precondition at the door telling you to open up or be shot down. It is the Serb police, and they are telling you that you and your whole family had to leave your home immediately. This is how it went for many Albanian state during what some Serb extremists called demographic genocide. This was the beginning of what many would call the Kosovo War, and it lasted from March to June 1999. After NATOs intervention in Kosovo, something strange happened. Now the people organism victimized were the Serbs and anyone who was friendly to them. In this paper, I will speak about what happened before and after the war in Kosovo. Most war victims during the Kosovo War were considered victims of ethnical cleansing, which is the internationally condemned practice of driving out members of other nationalities from territories that had been part of the SFRY (Socialist Federal Republic of Yugoslavia) . All of this began with the presidency of Slobodan Milosevic in 1988 who was president of the Serbian League of Communists and also Serbia a year later. He began a campaign to reassert communist dominance as well as Serb dominance. He purged into countries such as Croatia and transform its army from one that wanted to preserve Yugoslavia to one that wanted unification of all Serb populated territories and eventually create a Greater Serbia. A instruction that Milosevic felt he could achieve that task was through a strategy of ethnic cleansing and the expulsion and massacres of the non-Serbs.Milosevics main goal in Kosovo was to oust Kosovo Albanians population in an effort to ensure continued Serbian control over the province.

Analysis of Virtual Reality Essay -- Virtual Reality Technology Comput

Analysis of Virtual RealityThe term Virtual Reality (VR) is use by many different people with many meanings. There ar some people to whom VR is a specific collection of technologies, that is a Head mount Display, Glove Input Device and Audio. Some early(a) people stretch the term to include conventional books, movies or pure fantasy and imagination. However, for purposes of this research, we restrict VR to electronic in functionation processing system mediated systems. We would define Virtual Reality as a way for humans to visualize, manipulate and interact with computing devices and extremely complex data.The visualization part refers to the computer generating visual, auditory or another(prenominal) sensual emergeputs to the user of a world within the computer. This world may be a CAD model, a scientific simulation, or a view into a database. The user can interact with the world and directly manipulate objects within the world. Some worlds are animated by other processes, perhaps physical simulations, or simple animation scripts. Interaction with the virtual world, at least with near real time control of the viewpoint, is a critical test for a virtual reality. Some people object to the term Virtual Reality, saying it is an oxymoron. Other terms that have been use are Synthetic Environments, Cyberspace, Artificial Reality, Simulator Technology, etc. VR is the most common and sexiest. It has caught the attention of the media. Types of VR SystemsA major distinction of VR systems is the mode with which they interface to the user. We would describe some of the common modes utilize in VR systems.

When the inspector completes the inspection, no further input is required. The inspector is not required to take notes and so pass them off to someone else to decipher and input to the system. The information is already in the maintenance database and ready for verification, planning, and scheduling. The timesaving realized from start to finish of that inspection is 30-50% depending on the inspector and the aircraft.

Islamic State in Iraq and Syria Essay

Muslim stir in Iraq and Syria (ISIS) is one of the biggest threats the Middle easterly is facing right now. ISIS started in Iraq in 2004 where a person called Abu Musab Al-Zarkawy established Al Qaeda in Iraq. During his time as Al Qaeda drawing card in Iraq Al-Zarkawy tries to make genocide against the Shiaa (another Islamic belief) population living in Iraq, eventually Al-Zarkawy gets killed by a US airstrike and Abu Ayub Al-Masri takes over and announces the formation of Islamic State in Iraq at that time. Al-Masri similarly gets killed by in a joint American-Iraqi operation and then Abu Bakr Al-Baghdadi (the current leader) takes over.In April 2013 ISI declares that it will join with Al Nusra await in Syria (Another terrorist organization and Syria) forming the Islamic State in Syria and Iraq. Later that month Al-Nusra leader rejects that merge, and then AL-Qaeda broke ties with ISIS for being too extreme. ISIS aims to make an Islamic Sunni state across Iraq and Syria. ISIS i s known for doing a lot of atrocities to its victims including public executions and group murder. ISIS has many victims including the Shiaa population, the Christian population, and any Sunni who dares to oppose their views or ideologies. The group has beheaded 3 American journalists until now and will do it again if it finds another foreign journalist. The so called Islamic state controls hundreds of square miles and still till this moment trying to capture more lands by attacking villages and cities. The groups at first tried to make notes by extortion and robbery moreover now he gains money by capturing cities.ISIS till now has about ten thousand followers. ISIS is not only a human rights and political issue it is also a long scotchal issue in the Middle East. The ambassador of Italy in Saudi Arabia, Mario Boffo said I hope this phenomenon will disappear as soon as possible, because it can affect the regions economy if the situation lasts for another year, Investors will b e scared to come not only to Saudi Arabia but also other countries in the region, As Boffo said the ISIS economical threat in the Middle East isnt only in Saudi Arabia, it is also in the Arab states, especially those who are in the GCC. The Arab states in the GCC are spending billions of dollars on infrastructures that require international labor and international expertise. Therefore Italy, America, Qatar, Saudi Arabia, and UAE make a coalition to respond to the ISIS threat in Iraq and Syria without sending troops on the ground.Although the ISIS threat is far away from the United States of America we will rent some economic problems. As we all know the Middle East is the most part in the world that exports oil to the world including the United States of America. If the ISIS threat grows and stretches to places like Qatar, the United Arab Emirates, and Saudi Arabia then the oil industry might enter in a worldwide oil disaster. If the ISIS threats continue the oil harm in the worl d market will rise causing the price of oil here in the US to rise as well. In my intellection ISIS is a threat we should face sooner than later because in every day we lose innocent lives are being taken the more economic problems we will have.

My Belief System

A belief ashes is the combination of thoughts, opinions, or convictions on the most profound questions of life. What is a human being? What is the meaning and point of life? What is righteous behavior and what is sinful? Why is so much suffering caused and does it have any purpose? How can a greater and fixed happiness be found in life? What happens at decease? What happens thereafter? Is there anything such as judgment? Will the righteous be rewarded? Such argon the questions that weigh heavily upon any person seeking a deeper meaning of life, and possibly the way to salvation.They atomic number 18 no easy obvious answers to these questions. One can non come to any clear-cut conclusions to these questions using mentation and analysis, although philosophers do try to do so. The ultimate questions of life belong to the dimension of metaphysics, and have to be largely accepted as a matter of belief or doctrine. The articles of a believers religious faith are not conclusions deri ved by ratiocinative, discriminating mind. wittingness has little to do with them, they are more related to the heart and the soulfulness of a person.For example, the existence of soul itself is not something one can infer from apt analysis or physical dissection. Yet the existence of soul is central to nearly every religious belief system on the earth. Logical opinion cannot desexualise anything of such a belief. Similarly, the presence of matinee idol is something beyond the reach of human mind to comprehend. Yet, a belief in God is once more the sum of nearly every religious belief system. I myself follow a deeply Christian belief system that is founded upon the Glory of God and the mystery of His creation.When we cipher the domain of a religious system, we have to leave the mind behind and follow the voice of the heart. I believe that we should follow a belief system not because our parents followed it or the people around us follow it, but simply because there is a reso nance between the elements of that particular religious thinking and oneself. Of course, usually one harnesss this special affinity to the religious tradition one is born into, and that is the case with me too.I am a Protestant Christian and I find that the Protestants have a direct and intimate approach to religion. I am at home among Protestant Christians and particularly in my church and denomination, the Baptist Christians. Though I myself belong to the Baptist church, and have certain strong convictions concerning theological/metaphysical matters in accordance to my particular belief system, I try to regard other denominations and point faiths with an open mind. I believe that deep down, the religious impulse of men and women all over the world is the same.Further, the courage or abstractness of thought needed to tolerate the heart to believe in completely unseen things is similarly more or less the same, although I acknowledge the fact that in a mass of cases, religious b elief are just a matter of custom which do not have serious implications in a persons life. But when religion is taken seriously, the essential nature of divergent belief systems can be the same though the contents differ, sometimes radically as between Eastern pantheistic religions and the strictly monotheistic Judeo-Christian religion.I believe that Gods mystery is so great that it can perhaps til nowly validate widely differing religious belief systems. Let me offer a relevant example here from the world of physics an electron can be a particle and also a boom at the same time. Common sense tells us that something cannot be a particle and a wave at the same time, surely that is impossible in the very nature of things and yet in reality it can happen and in fact this is how things are. Similarly, Gods mystery can be so vast that it can accommodate two or more apparently conflicting metaphysical viewpoints.Thus, near paradoxically, although I am strong believer in the tenets o f my own faith, I do not fanatically or arrogantly claim or even think that my denomination, my sect, my religion, is exclusively correct and all others wrong. I believe that ultimately, the mystery of God cannot be contained by any particular belief system. I also believe that more than the specific doctrines of a belief system, what is more important is the passionate intensity of the believer in God, whatever may be the note of the God. I believe in the efficacy of prayer and the total need to feel in person connected to the divinity of God.To me, that divinity is represented in the design of Jesus Christ. As everyone knows, Baptists insist that one has to fully accept Jesus Christ as Lord and Savior as a personal conscious choice, not as just a matter of course. The event of Baptism marks this choice or decision. Although all Christians follow the ceremony of Baptism, and I respect that, I personally think (and not simply because I myself am a Baptist) that such a most sacred event in ones life which confirms ones personal relationship to God cannot be simply imposed on children who are not mature enough to make decisions for themselves.Making Baptism into a matter of tradition and custom, instead of being a reflection of the most deeply heart-felt conviction is trivializing it. And I am proud that I am born into a particular system of faith that recognizes this and places so much importance on the act of being born over again. For me, being born again is not just a matter of belief of doctrine, but a tremendous inspiration at every step of my life. I also personally believe that being born again is not a one-time event associated with Baptism and does not end with it, in fact it only begins with it.One has to be born again and again in spirit. Ones faith in God has to be renewed, rejuvenated and reaffirmed every day, only then the stream of faith can be kept flowing instead of becoming frozen. The belief in God, after all, is not simply a matter of be lief anyone can believe anything, and it does not make much difference what makes the difference is the living energy and intensity that goes into prayer which forms a personal connection between the soul and God. There are numerous distinctive tenets in the Baptist faith that are the result of a well-grounded biblical, theological reasoning.However, as I mentioned already, ultimately belief goes beyond reasoning, in its intensity and authenticity it even transcends the particular forms and structures it outwardly conforms to. Let me reiterate the fact that religion is a personal heart-to-heart affair between the soul and God. It is more like a love relationship than a particular type of world-view. The religious quest begins with questions such as what is the meaning of life, what happens after death and so on. A belief system provides or is supposed to provide answers for them. But how do I know that they are true, and absolutely true?In this context, people usually say that that is the meaning of belief one accepts a certain element of belief as a matter of faith kind of than a demonstrable fact of knowledge. I agree to that entirely. But I would like to go a little further. To me, my particular belief system does not provide all the answers to all the questions, such as why innocent children have often to suffer so cruelly, or why millions of people are dying in Africa from hunger and disease. In a world governed by a compassionate and infinitely wise God, how can such and so umpteen other atrocious things happen constantly and everywhere?There are no easy answers. My belief-system does not provide satisfactory answers to these questions, but my personal faith in the wisdom and power of God allays my questioning mind. There are no clear and distinct answers, but the questions themselves become amorphous and disappear in the burning intensity of ones faith. To have faith in God means to have faith that whatever is happening, is happening for certain rea son, though it may not be easy for us to comprehend Gods ways. To a praying heart, ultimately, the one answer it needs is found in the triumph and upliftment to be found in the act of prayer.

This shows that the rate is directly proportional to the concentration of I- and S2O82- and by calculating the gradient of the graph we will obtain the rate of reaction. f) Write the rate equation for reaction (1) dI2dt=kS2O82- And calculate the rate constant , k Rate = kI-S2O82- k = Rate / I-S2O82- k = slope / S2O82- k = (0. 015-0. 0008)/(0. 15-0. 05)Rate constant k = 0. 142 mol-1 dm3 s-1 g) Calculate the brawniness of activation of the reaction If we plot a graph of log t against 1/T, we can obtain the Ea by calculat ing the slope. Slope of the graph = Ea / 2. 303R Ea / 2. 303R = (1. 462-0. 903)(0. 003472-0. 003145) Ea / 2. 303R = 0. 559/(3. 2710-4) Ea = 1709. 48 x 2. 303R Ea = 1709. 48 x 2. 303 x 8. 314 Ea = 32731. 65 J/mol Discussion Precautions Among some of the precautions taken were to wear gloves , safety goggle and lab coats to avoid any injury in case of exposure to chemicals.Secondly, there were separate measuring cylinders prepared for each solution as to non mix 2 solutions in a measuring cylinder to avoid any reactions. The persulphate was poured in rapidly as this is an extremely fast step and has to be poured all at once. Finally,when diluting the persulphate solution, it was d unrivaled as accurately as possible in order to avoid a wrong concentration instead of the one intended. Conclusion Based on the experiment done as well as the analysis of the results and after doing further results, we have learned that the activation energy of the reaction is 32. 73 kJ.Furthermore, we hav e gained an insight into the kinetics of a reaction, its rate, the rate constants as well as the rate of reaction.
