Free Essays on Disfunctional Aspects Of Leadership

Disfunctional Aspects of Leadership When people think of a leader, they think of someone who possesses a number of qualities. They would like to think that he or she is enthusiastic, has good judgment, intelligent, a great speaker, and a good people person as well. Even though all these qualities make up an effective leader, there are still different aspects, which may not be effective, such as Dysfunctional aspects. A leader should stay away from, going against their word, not being open to opinions, and showing weakness in many dysfunctional aspects. Before a person can determine if an individual is a good leader, he or she must know what exactly leadership is. What is leadership? â€Å"Leadership is having the ability to give guidance to those that will follow you† (Rose 1998). â€Å"Those that follow will strive to help complete the mission† (Rose 1998). â€Å"Leadership is an immature science and the body of knowledge in the field has developed through a series of fits and starts† (Jansen 2001). â€Å"Leadership is a soft science, just as anthropology, psychology and sociology† (Jansen 2001). Leadership is power, but only when effective. A significant part of effective leadership is the close connection between the individual leader and his or her followers, as Jansen states (page 205), the success of the leader’s mission. â€Å"Leadership, which comes in many different types of forms but basically heads toward the same goal to communicate with people can be very effective in terms of communication† (Rose 1998). â€Å"Some people are silent leaders and lead by example some are more vocal† (Peter 1996). Nevertheless, whatever type of leader they are, there are certain criteria that must be met before being effective. For example being a dependable role model of some sort, being trust worthy, are things that a true leader must possess to be effective. To be effective they must realize that there are strengths, weaknesse...

What is a group Discuss with reference to Bion's 'Experiences in group' and your own - Essay Example It is because lovebirds are sociable birds. They should go in pairs or in a group.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  We join others wherein we feel a sense of belonging and security, thus becoming a part of a group. We seek to join aggregates that have common entity with us. We stick to a group because we know that this group have something the same about ourselves. Being a part of a group is therefore important in a person’s life for survival.   Every individual has its own niche therefore each is essential. It may be towards others or towards the environment.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Group is defined as any social aggregation that contains at least two classes of people we refer to as â€Å"the leadership† and â€Å"the membership† or a more complex structure one having an external boundary and at least one internal boundary.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  (2).   This enables us to view a group as a large circle whose external boundary   distinguishes its members (those inside the circle) and nonmembers (those outside the   circle) with a smaller circle inside the larger one represents the existence of the important   two classes of people in the group, the leadership and the membership.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Theorists like Cartwright and Zander (1968) on the topic groups and group dynamics have suggested that group is not a definable idea since it merely describes an area of study whose boundaries are blurred. Various definitions of groups can be made according to them wherein each one has its unique focus and may exclude other aspects that serve as core of the other definitions. 1. The individuals within the group think that they are group members who refer to themselves as we rather than I or they. They experience the same fate thus feeling a sense of belongingness and a common sense of identity. They are equally provided with the same benefits as to what the other members receive. 2. These group members have psychological effects on each other. These

First Essay Prompt Example | Topics and Well Written Essays - 1000 words

First Prompt - Essay Example What we see is only our dim reflections on the walls, metaphor for our imperfection and ignorance. There are prisoners in the cave who are chained to the floor in the darkness and unable to move their bodies to see what is happening around them. Under the protection of a parapet there are the puppeteers who display shadows on the walls. The prisoners are disillusioned that this is their reality. The story is told not from the perspective of the prisoners, but rather as a conversation between Socrates and Plato's brother - Glaucon. Plato's idea is that people are governed by the supreme forces of nature and Gods and we are unable to control our destiny and life. Everything is decided upon Gods and they are who captivate us and release us. And because people are under the possession of a higher power, we can not understand. Scharffenberger and Jowett (2004) comment that Plato's work "Republic" is identified mainly with the concept of the good. Plato's philosophy is often written as conversations and dialogues which shows that before reaching some conclusion the readers must be pres ented with all arguments and viewpoints (Scharffenberger and Jowett, 2004). In the "Allegory of the Cave" scene Socrates is the one describing the situation in the cave and he is the one to convey the idea that behind the prisoners puppeteers exist who move objects to resemble the reality. Another important aspect of the story besides our human imperfection and wrong interpretations of reality and goodness is that we often give names to objects to make sense of the world. However, language appears to be the limit of our understanding for the physical objects that surround us, and the invisible remains indecipherable and unreachable for our mind. Our thinking is bound by our imagination and we can think as long as we see and witness existence with our sense. Beyond this, our mind can not grasp other realities. Thus, human knowledge is full of mistakes and too limited. Once the prisoners of the cave are released they face different world - they see the sun, the light, the people around. They realize that these new images are the "truth", the reality. Now prisoners change their perceptions and start to believe that the sun leads their own existence. Scharffenberger and Jowett (2004) remark that this is the climax of the storyline - people regard as good what they are presented with. Then human goodness and knowledge are questionable, since they are not omnipresent and we do not possess them by nature. We have to discover them alone. So goodness and knowledge are controversial, because they depend on individual's reactions and beliefs. And there is no ultimate, supreme notion to unite them for all human beings. Apology is Plato's interpretation of Socrate's speech where they accuse him corrupting the young men of Greece through worshiping gods, which are not recognized by the state. With Apology Socrates defends himself and give reasons for his actions. "The Delphic Quest and the Gadfly are the two poles of Socrates' public self-vindication: the one submissive to the dawning wonder of the complexity of political and moral affair, the other aggressive in the hunt for clarification of this wonder (Newell 98)." Newell (2000) remarks that Socrate's philosophy consists of two dimensions. The holistic - represented by the Delphic Quest in Apology, and the analytical - embodies by the Gadfly. Socrates'

Why do I have to take economics Essay Example | Topics and Well Written Essays - 500 words

Why do I have to take economics - Essay Example The main question is that why should I take economics as a course? There are a lot of reasons supporting the cause. First of all the world relies on economics. All the activities and happenings in the world are based on economics. Economics is the mother of all social sciences. Although the subject is lengthy but still it’s interesting and gives you a clearer view about what is happening around you. For example you are watching BBC, or reading a news paper suddenly you come to the business section. You see that price of a share is increasing or decreasing, you get curious about the factors causing the price to rise or fall but you don’t know about it. Taking economics will give you a basic idea about the business world and how it operates. Microeconomics, as the name suggests, deals with the basic concepts like demand and supply, elasticity, returns and more basic things. The change in price of a product due to a shift in demand is a basic thing. One other point in favo r of opting economics as a summer course is that the student gets to know about the working of an economy.

Depictions of the Reformation in Art

Depictions of the Reformation in Art The corruption and immorality of the Church spurred the Christian Reform movement in Europe, eventually leading to the hundred years of civil war between Protestants and Catholics or the Protestant Reformation. The Counter- Reformation began with the Pope Paul IIIs calling of the Council of Trent in response to Protestant uprising; this movement was initiated by the Churchs attempt to re-establish its power as the only true Church of Christ while pacifying the current disorder as well. The creation of these two rivaling movements jeopardized the Roman Catholic Churchs absolute authority in Europe, dividing it into the regions of the Protestant North and Catholic South. Influenced by these two opposing movements, the North and South branched out into different directions in terms of its culture and artistic style of painting. They developed unique style of painting, depicting differing themes, styles, and contents based on their dissimilar beliefs. What influence did the reform moveme nts have on the paintings from the south of the Alps, the north of the Alps, and the Netherlands and were the artists from these regions inspired by each other despite the divergence in their styles? The paintings by the artists from the South of the Alps would most likely been influenced by the Counter- Reformation, while the works produced from the other two regions would reflect the influence of the Protestant Reformation due to their geographical locations. Therefore, the content and purpose of the works from these regions should differ but some similarities may exist in the artists painting techniques because it was common for artists to travel to Rome during this time. It is interesting to analyze how the style in 16th and 17th Century Europe was shaped by the religious disparity and the development of new ideas which were reflected in the paintings. Since it is inaccurate to generalize the whole European continent into only two sections, I decided to narrow down my topic by focusing on the South of the Alps, the North of the Alps, and the Netherlands. I chose to study these regions because the South of the Alps was the center of Counter- Reformation strongly embraced by the Roman Catholic Church, while the North of the Alps was the birth place of the Protestantism. And the Netherlands was the hot bed for dispute between Calvinism and Catholicism. I referred the Protestant Reformers as one group, choosing not to deal with the Protestant sectarianism, a division within the Reformers due to the difference in their interpretation of the sacred texts, as part of my research. The final spark of the Protestant Reformation was The Ninety-Five Theses written by Martin Luther in 1517. His work disclosed Churchs dishonesty, rousing doubts in peoples minds about the Catholicism and also the Churchs authority. His criticism of the sale of indulgences and the Roman Catholic clergys abuses quickly earned popularity among people, regardless of their social standings and wealth, ultimately giving birth to Protestantism. Martin Luther condemned the sale of indulgences as a violation of the original meaning of confession and penance. Indulgence is the forgiveness of the temporal punishment for sins that have already been confessed. Reformers like Zwingli and Calvin had also commented on the corruptions within Church, but Luther was the one who introduced the radical idea of purifying the Christianity by physically breaking away from the Roman Catholic Church. The Luthers idea spread rapidly throughout the Europe, threatening the Roman Catholic Churchs established auth ority especially in the North. In addition to being known as the center of the Counter-Reformation, the South of the Alps was known as the center of stylistic development as well. It was the place of passion and innovation with the overflow of new artistic styles eventually giving birth to the Italian Renaissance. The artists from all of the Europe visited Rome and were inspired by the unique Italian styles. Aside from the innovative styles of Italian Renaissance, its content was often strictly religious. The Roman Catholic Church attempted to re-establish the catholic faith among people by regulating the artworks produced. The southern painters were forced to bring back the medieval tradition of producing strictly religious art, branching off into the different direction from the Northern painters. Scipione Pulzone was famous in Rome as the prototype of the Southern painters during this time period for his strictly religious paintings. The Lamentation, one of his most famous paintings, serves as the prime example of the art commissioned by the Church. Painted in 1592 for the chapel of the Passion of Christ in the Jesuit church of Gesà ¹ in Rome, this painting is clearly influenced by the Counter- Reformation in that it demonstrates the new artistic style advocated by the holy council. The Crucifixion of the Christ is the focus of this art piece, drawing viewers attention directly to the idealistic image of Christ in the center. Like other southern painters during this time period, the artist propagated faith by portraying the lives of saints and Christ in a realistic yet intensely dramatic manner. The careful details, facial expressions, along with the shadows cast on people enhance the lifelike characteristics. The depiction of the folds on peoples gowns is also note-worthy. The artist adds details such as tears of Virgin, the crown of thorns held by John, and the pallor of the Christs body to portray people in a more expressionistic manner. Moreover, the spotlight on the Christ in the center contributes an illusionistic and dramatic element to the painting which counter-balances the paintings realistic image. The light cast on the Christ, in comparison to the dark background, creates almost a theatrical impression. These characteristics represent the style of art in the south of the Alps during this period, also called the Italian Renaissance. Catholic Italy and Lutheran Germany shared in a lively commerceand the art of the sixteenth century in the north manifests the benefit of the exchange. Although the religious clash tormented the sixteenth century Europe, the exchange of artistic ideas continued to thrive. In the North, the intellectual shakeup of age-old faiths and opinions prepared the way for a new and nonreligious outlook on the world-the Enlightenment-when the rise of a scientific view of nature would challenge forever the dogmatisms of the past, also called the Northern Renaissance. However, the art of northern Europe during this period is also characterized by a sudden awareness of the advances made by the Italian Renaissance and by a desire to assimilate this new style. In other words, while the content of the artworks produced in the North differ from those of the region south of the Alps, the style was similar. Many northern artists traveled to Rome to study the new art in firsthand and others were exposed to the Italian style of painting through the direct contact with the Italian artists who came to the north. The influence of the Italian art varied according to the artist, the time, and the place; the northern artists generally kept their local traditions while adopting on ly single motifs or the general form of a composition. The Northern painters in general moving away from depicting biblical scenes and turned to painting ordinary people in a commonplace setting can be inferred to have been influenced by the Protestant- Reformation. Especially in the north of the Alps, the artists quickly incorporated Italian style into their artworks while avoiding portrayal of religious themes. The famous work, The Battle of Issus, by Albrecht Altdorfer in 1529 is a great example of a northern painting that diverges from the works produced in the regions south of the Alps. Albrecht Altdorfer represents the Donaustil (Danube Style), which depicts the landscape and stresses mood and passion. Although Altdorfers style is unique and personal, it still reflects the influence of Protestant- Reformation in that it eliminates depiction of religious themes. Moreover, his style clearly diverges from the style of painting prevalent in the regions of the south of the Alps. The painter gives a birds eye view of an Alpine landscape as the setting and depicts the battle scene in which the Alexander the Great overthrows the Persian King Darius. Instead of illustrating the strictly religious theme, the artist chooses to focus more on depicting the historical event. The crowd of people in comparison to the vast nature in the background suggests the moralizing theme of the insignificance of h uman life. He uses the vast nature in the background to symbolize the power of cosmos and the illuminating sky to represent the immense space. The slight trace of Italian Renaissance is shown by the meticulous details the painter uses for the image of Alexander the Great and the dramatic and illusionistic portrayal of the setting. Also the idealistic impression of the artwork as a whole resembles that of the Italian Renaissance paintings. Another praise-worthy example of Northern painting is The Judgment of Paris by Lucas Cranach the Elder, who is the representative of German Protestant painting. This work is a great example of how his works shifted from religious to humanistic subject matter when he became a follower of Luther. His humanistic subject matters include mythology, history, and also portraits. The Judgment of Paris illustrates the scene from mythology in which the three goddesses boast off their beauties in front of Paris. The humanistic subject matter along with the background landscape reflects the typical characteristics of Northern paintings. The cupid in the painting serves as a symbol for love and affection while the German armor that Paris is wearing in the painting represents his social status as a knight and his honor. The artist does not dress the goddesses after the antique manner. Cranachs composition featuring the nude was inspired in an attempt to learn from the style of Italian Renaissance. The Four Apostles by Albrecht Durer in 1526 is a remarkable northern painting that is stylistically influenced by Italian Renaissance. This art piece is unique in that the painter expresses his own religious and political testament, sympathizing the protestant cause and [warning] against the dangerous times, when religious, truth, justice, and the virtues all will be threatened. Unlike other Northern paintings, this piece does contain religious meanings, but it distinguishes itself from Italian paintings by eliminating any glorification of the Church. This piece was hung in the city hall, the four apostles symbolically representing the guardians of the city; they are cautioning people against the sermons of false prophets who will misinterpret the word of God. The four apostles are symbolic representative of various ideas such as the four temperaments, of the human soul, and also the four ages of man. In this painting, Durers experience of traveling to Italy allows him to harmonize t he two opposing styles of northern naturalism and southern monumentality. The realistic visualization of the four apostles reflects the northern naturalism while the monumentality of the figures along with the vivid use of color and sharp lighting mirror the Italian Renaissance. Durer, along with Cranach and Altdorfer, serves as an example of northern artist who illustrated contents related to Protestant-Reformation while incorporating styles of Italian Renaissance into his paintings. The Netherlands was the exceptional region in North in which Calvinism and Catholicism co-existed. In the late 16th Century, the Northern Netherlands was able to break away from Spains influence, while the Southern Netherlands remained under the rule of Spain. Therefore, the Northern Netherlands eventually embraced Calvinism while the Southern Netherlands remained as supporters of Catholicism. It is important to realize that Dutch and Flemings were not predestined to become Calvinists and Catholics; it was solely caused by the geographical and military circumstances. No curtain existed between the North and the South that forbid the exchange of ideas. In fact, Constantin Huygens, a diplomat and an art critic, referred to great painters of Amsterdam, Utrecht, and The Hague collectively as the painters of Netherlands. Therefore, it cannot be concluded that the Northern Netherlands was only influenced by Calvinist ideas, which also applies to the Southern Netherlands. In the early 17th Century Catholicism was suppressed and catholic churches were demolished due to the iconoclast movement, but the protestantizing of the Northern Netherlands was still a slow process. Most artists chose to remain as Catholics, although exact number is hard to determine. However, the attempt to repair damage caused by the iconoclast movement was not as extensive and as systematic in the North as in the South. The Northern Renaissance in the Netherlands took on a completely different form from the Italian Renaissance because the Church no longer was the major patron in the North. Instead, the wealthy merchant middle class were the primary patrons of the art and thus, the Dutch masters painted small pictures for their small houses, not for the Cathedral altars. Since large church commissions were no longer available, artists changed their styles in accordance to the taste of their new customers. The artists from the Netherlands specialized in intense realism, depicting lifelike features with an unflattering honesty, unlike the Italian Renaissance painters who specialized in idealism and simplicity. Therefore, the basis of art for the Northern Renaissance was observation while for the Italian Renaissance, it was theory. The Northern Renaissance in the Netherlands indirectly reflects the influence of Protestantism in that religious themes no longer prevailed in art, although more direct causes were the changing structure of the Netherlands economy and culture. The artworks produced in the 17th Century Netherlands were more conservative compared to those of Germany, concentrating on the nature and the past times of the prosperous Dutch merchants. The direct portraits, realistic still-lifes, landscapes, marine-scapes, and genre paintings showing scenes of everyday life were popular subjects of the Dutch artists. A Scene on the Ice by Hendrick Avercamp in 1625 is an accurate representation of a typical Dutch style, illustrating the commonplace scene of people enjoying winter sports in the quiet village of Kampen northeast of Amsterdam. His style clearly reflects the Northern Renaissances realism and its use of details, faithfully depicting the winter. He enhances his realistic rendering by using a frosty day to convey a sense of depth; the pearly gray tonality here becomes ever paler and the forms less distinct as they move into the distance. His work is unique in that it successfully portrays all classes of Dutch society through by using meticulous details, from the poor fisherman surveying the skater to the well-dressed ladies riding in an elegant sleigh driven by a groom. This is the typical genre painting of Northern Renaissance departing itself from the religious influence of Roman Catholic Church of Italy. A seascape, along with landscape, also became very popular in Holland due to the rise of merchant class; view of Dordrecht from the Dordtse Kil by Jan Van Goyen painted in 1644 serves is an impressive seascape painting. The artist uses monochromatic phase, which is a technique in which a single color dominates the painting, to unify each view of nature; the golden brown aura dictates the scene, from the hazy clouds to the city skyline. He reached the summit of Northern realism by lowering the horizon to focus more on the atmospheric conditions overhead and by creating an illusion of standing on the opposite shore of the port. Unlike the Northern Netherlands, the Southern Netherlands was more influenced by the Counter Reformation than the Protestant Reformation. The Reborn Catholicism in Spain had an undeniable impact on the Southern Netherlands provinces. Moreover, France sent numerous religious orders and congregations to Spanish Netherlands in order to secure the Catholics authorit y. The disparity in the contents of the paintings resulted from the disagreement in Protestants and Catholics perspectives of the human relationship with god. Unlike the Protestants who claimed that humans are capable of having a direct communication with god, the Catholics argued that intermediaries, such as saints and the Virgin Mary, are essential for humans to connect with god. Therefore, Catholics created artworks of saints, the Virgin Mary, and Jesus and gave reverence to them, as a way of getting closer to god. Although the Catholics asserted that they are not worshipping the intermediaries, the Protestants criticized this practice and led the iconoclastic movements. Iconoclasm is a deliberate destruction of religious icons and symbols within ones own culture for religious changes. The Protestants and Catholics conflict was caused by the difference in their perspectives of the sacred and secular;while the Catholics maintained the clear separation of the two, the reformers recogni zed the connection between the two. Consequently, the Roman Catholic Church clergy advocated strictly religious and sacred artworks whereas the reformers preferred artworks depicting the lives of ordinary people. The Northern Protestant painters believed that an ordinary life could glorify God just as much as a life `in the ministry ; since god created humans in His image, the reformation artists claimed that they are glorifying god by portraying the natural beauty of his creation, in other words, the people. These differing ideas are well conveyed through the artworks produced from the regions south of the Alps, north of the Alps, and the Netherlands mentioned above. My thesis is partially proven to be correct in that Italian art was definitely influenced by the Counter- Reformation and that German art was influenced by the Protestant- Reformation. But contradicting to my statement, the Netherlands was influenced by both religious movements. According to the Art History Professor S arah Blick from Canyon University, the Counter- Reformation had a more direct influence on art produced after 1520s then the Protestant Reformation. Therefore, she suggested me focus on the lack of religious content in the artworks in order to study the influence of Protestant Reformation during her interview. Although artworks from each of these regions have distinct characteristics that set them apart, Italian style of painting frequently perceived in these artworks indicate that artists were inspired by each other. Because I had to narrow down my topic, many new questions emerged from my research. I am curious to know whether the various Protestantism had different influences on art. For this research, I referred to Protestants as one group but I want to extend my research so that I can investigate on the influence of the Protestant Sectarianism on art.

Surrogate Motherhood Essay -- essays research papers fc

Surrogate Motherhood: Good or Bad?   Ã‚  Ã‚  Ã‚  Ã‚  There are many controversies surrounding the idea of surrogate motherhood, by its definition, it is a course of action that goes outside natural reproduction. Although surrogacy was first brought up in the bible it is only until recently that it has actually become an issue for criticism and debate. Factors such as the growth of infertility in modern society, coupled with the declining number of children available for adoption, and the development of surrogacy contract and commercial surrogacy agencies in 1976, have resulted in increasing publicity and public interest in the formation of agreements between infertile couples and surrogate mothers (Stuhmcke, 3). Surrogate motherhood can be approached in more than one way, and some surrogacy procedures receive more condemnation than others.   Ã‚  Ã‚  Ã‚  Ã‚  One type of surrogacy is when an egg is extracted from the infertile female and placed in a petri dish and is then fertilized by the fertile male’s sperm, the fertilized egg is then placed into the fertile female’s uterus so she can give birth to the child. This procedure is done when the uterus of a female is in some way defective, but her eggs are in fine condition, this is called invitro fertilization surrogacy or IVF surrogacy (Hanafin, 3). IVF surrogacy, or total surrogacy is the procedure that receives the least criticism because the baby is in no way related to its carrier. The more comm...
