Free Essays on Greeks Belief In The Afterlife

â€Å"What beliefs did the ancient Greeks have about life after death. In your opinion have these beliefs had any influence on modern thinking about life after death.† There were many different beliefs, theories and ideas within Greek culture as to what happened to someone once they died. The most dominant of these numerous beliefs was Hades. Legend has it that Hades, one of the brothers of the King of the Gods, Zeus was appointed with the job of being King of the dead. The Greeks believed Hades ruled the ‘underworld’ the land, which you inhabited once you died. Other such possibilities were that after death you transformed into stars, being absorbed into the upper atmosphere, others believed in the re-incarnation cycle, while others thought your soul lived on in another place, amongst these places being the Isle of the Blest and the Elysium Fields. These examples are just a handful of the explanations the Greeks gave to the afterlife. It is doubtless the Greeks were fascinated by death, and glorified it in such a way that would disgust modern societies. They paraded funerals and spent their lives living for their death. This could be because they expected a better life once they’d lived on earth, weather they returned to earth again in another form was debatable, but it was not unusual for people to spend their lives working hard to afford a spectacular funeral. According to Greek Mythology Hades ruled the underworld with his reluctant wife Persephanie, his kingdom was said to have been guarded by Cerberus; a three-headed beast who kept the living out and the dead in. Before souls could enter his kingdom they were taken down by Hermes and had to cross the river Styx. Their fare was paid to Charon who rode them across by a silver Obal coin, which was placed in their mouths once they died. Sailors who were away from home had their fare in the form of a silver earring. Those who did not have the Obal were sentence...

Theory Preposition - Research Paper Example Each of these two approaches focuses on and deals with different features of client dialogue. As a consequence, they follow different techniques of resolving problems. Nevertheless, both have the objective of helping the client, reconciling discrepancies, and mitigating conflict. This essay compares and contrasts the major tenets, concepts, techniques, views of pathology/normality of cognitive-behavioral therapy and person-centered therapy. It also discusses the usefulness of both therapies to advanced nursing practice. Comparing and Contrasting Cognitive-Behavioral Therapy and Person-Centered Therapy Cognitive-behavior therapy (CBT) is a framework of human difficulties and challenges that can be approached from primarily two interconnected domains: philosophical and theoretical. Within the philosophical perspective, CBT can be regarded as being related to some forms of behaviorism. The behaviorist models are commonly philosophies of mind and science, specifically, methods of identif ying and dealing with the interpretation of the problems or difficulties usually related to psychology (Sharf, 2011). On the other hand, the theoretical feature of behavior therapy is more about actual identifications of particular problems. Theories can give reliable explanations or at least verifiable assumptions for issues about more exact problems (Sharf, 2011): How does this problem arise? What are the fundamental features of this form of medical disorder? What are the possible techniques for problem modification? Basically, CBT is a type of psychotherapy that has been shown to be one of the best methods for treating a broad array of disorders such as anxiety and depression. CBT targets thought and behavioral processes that reinforce both normal and abnormal behavior. It rests on the idea that these processes are learned, and, therefore, can be unlearned. CBT is described as collaborative, participative, and brief (Corey, 2009). Even though therapists take into account how diso rders may have emerged, their main interest is in helping the patient pinpoint, understand, and modify what is reinforcing the problem. The therapist-patient relationship is characterized by partnership or collaborating, and patients are motivated to actively participate in the application of techniques during therapy sessions. There are four major techniques employed in CBT: skills training, exposure therapy, behavioral activation, and cognitive restructuring (Norcross, 2002). Skills training assume that some individuals keep away from particular situations because they believe they do not have the necessary skills to handle them. For that reason, CBT normally involves acquiring new behavioral abilities to handle difficult social circumstances and anxiety. Through exposure therapy, CBT helps individuals conquer anxiety by systematically confronting their fears. This technique rests on the assumption that anxiety is reinforced by avoidance (Sharf, 2011). On the other hand, depressio n usually results in indifference, avoidance, and withdrawal. Through behavioral activation, or the process of enhancing rewards, CBT helps individuals recognize and take part in activities or tasks that give them the opportunity to gain rewards or gratifying experiences (Norcross, 2002). Lastly, according to Corsini and Wedding

SWOT Analysis Manchester United

SWOT Analysis Manchester United Introduction The football industry in United Kingdom is booming and outwardly been successful in the past years. The research and strategic planing will be based on the case of Manchester United, one of the most famous and successful football clubs in the country. Due to this, the data acquired from the official website will be used as the basis and the analytical tool in examining the capacity of the company.The basic study on this report is based on Manchester United FCs internal and external environment factor. Critical Success Factor The main aspects of Critical Success Factors is based on 5 key sources there are understanding the industry, good competitive strategy and industry position, understanding the environment factors and good managerial position. Due to these 5 key the company should be success in its industry. MU is very success club in Barclay Premier league and the report is about the analysis why MU has success in its football industry. Porter Five Forces Competitive Analysis Suppliers The major component of a football club is the football team itself. The football team is made up of a variety of players with different skills, for example defenders, midfielders, attackers and the goalkeeper. These players are purchased from other clubs in the UK and around the world. The major problem here is that a club pays unreasonable sums of money for a player who is currently under contract with another club. Players can allow their contracts to pass and transfer free to another club but since they receive a proportion of the transfer fee, and so does the owning club, it is not really in their interests to do so. Thus, many clubs try to nurture their own talent by training young hopefuls and carefully talent scouting at other clubs. MU has its own academic to train for their potential and younger player to join their club there as well. Buyers Freely includes sponsors and television companies who provide the club with the revenue to purchase quality players. Football clubs try to tie in sponsors with long-term contracts and must ensure that the sponsor they pick has a similar consumer profile to the one that they have. There should be overlap between the supporter profile and the consumers that the sponsor wishes to communicate with. Buyers also include the football match attendees. These break down into occasional supporters, season ticket holders and frequent supporters. It is important that a club try to build on the loyalty of their supporters by providing more loyal fans with an enhanced package of benefits, for example season ticket holders get cheaper tickets and a discount on merchandise. Entry barriers Popular football clubs require large stadia. These are extensive and expensive service scapes both to develop and maintain. The cost of acquiring strong new players is also considerable. The ownership of football clubs is also regulated and media owners are not allowed to own more than a 10% share in any football club in the UK. The cost of setting up a football club is prohibitive and it seems that only the wealthiest of entrepreneurs and entertainers can afford the luxury of being a chief executive of a popular football club. The entry barriers could be lowered by purchasing land and building a stadium in a relatively cheap region, however, this strategy is often not viable because fans support their local or regional club and so the location becomes particularly important. Substitutes perhaps the closest substitute to watching a match live (revenue goes directly to club) is to watch the highlights or the full match on TV (revenue goes to television company and indirectly a proportion goes to the club). Where a club has a large fan base spread out over a disparate geographical region, the club might wish to offer its own TV station or Internet or mobile match news services. Competitive rivalry Other clubs represent the closest rivals and usually a fans loyalty to a particular club is intense. However, the author believes it is a myth that fans will never change loyalty to another club. They often do, particularly when they move to another region of the country or they cannot get in at their current club because of lack of space, prohibitive prices, and so on. The football game is also organised so that clubs need to beat each other in order to advance up the league tables. This generates a fierce loyalty amongst fans and a rivalry that is part of the enjoyment of football spectatorship. Reinforcement of this loyalty and the management of fans hopes and expectations is of paramount importance to a football club. Internal and External Environment Factor Analysis (SWOT analysis) (S)trengths The main strength of Manchester United is their brand awareness, Manchester United is outstandingly recognized worldwide, and if advertised as the general team with international sponsors. As a result, implies that any merchandise that they locate in the market, with the team name and emblem will be straight away recognized by their fans which could get there to a million. Besides that, Manchester United is having the great fan loyalty, ticket sales is also considered as strength for Manchester United, as there is a big waiting list for passes for every match, and with the new expanded arena, the income of ticket sales is bound to increase over the coming years. However, this is not the sole source of income for Manchester United and products are still required to be taken into account as the major part of total revenue by its retail store. The loyalty of the fans also is the main edge of the Manchester United against competitors, and this is due to the strong reputation of the Manchester United. Moreover, the company is also performance strong marketing effort towards their supporters by sending their prospect and loyal supporters their newsletters regarding the different activities and events in the company. Manchester United similarly possesses great distribution channels with various retail stores worldwide. This will be very helpful when introduci ng their new products. As these familiar connections are previously prepared, Manchester United have to guarantee that they are employing these channels to the full capability, and that these links for transmission can be engaged to feedback data in addition to flow out of the products. (W)eaknesses The main weakness that has been defined based on their website is their products and product variety. It is obvious that they have launched a lot of different products at many different occasions. There is an issue although whether the fans were consulted in this context. It looks like that MU has introduced a broad diversity of products from jerseys to Credit Cards. MU has been recommended that the club has merely exploited the more obvious income channels, and thus money-wise it would be more precious to perform more research in this field. The club obviously requires looking into their existing product collection and from this, they will be capable of situating their products, employing instruments like the Boston Matrix, and it will let the club to know which of their products are booming in the market. It is noticeable that even though the present products are selling well, this is a field where there will continually be a space for development, to suit their fans prerequisites in a profitable manner for the club. Another weakness for Manchester United is that currently, the club has been so thriving, and it is now working on such a massive level, there is a upsetting estimation that the club has now lost its origins, and it is no longer concerned with the game of football, but all about their profit or income. Unnecessary outlooks such as this can have a negative effect on the fans. Even though as long as Manchester United carries on performing well, this may not bring about too much worry for the club, as it has worldwide support; nevertheless, it is still required to be taken into account. (O)pportunities The main opportunity for Manchester United at the moment is the penetration to the American market. There is an opportunity in the proximate future to structure the coalition with one of the worlds most well-off team in sports, the New York Yankees. This will signal enormous merchandise channels in America, and provide Manchester United the lead over all other Football teams in the American context, presenting their product to a new market. Even though there is a superior height of risk concerned in tendering their products over to the US, then entering the existing market, by reason of the coalition with the Yankees, this danger is condensed. (T)hreats Manchester United is in a exceptionally firm site, as they have no direct dangers from any players in the industry. The most important threats that must be measured by the company are the growth or development of their competitors. This can occur if one of their rivals or new entrants had determined and figured out that the use of their Internet for their processes will result to competitive advantage. Due to this, there is a huge breach connecting Manchester United and the following strongest competitor. However, there are a number of dangers to Manchester United that has to be taken into account. Another threat to Manchester United at present is the Change of leadership in the team. Manchester United is required to promise that this will not affect the sales of its merchandise. Another less direct threat to Manchester United is lacking finances put into academies and junior football, from where potential players would initiate. However, Manchester United has used up in a football a cademy to train potential football players. Resources and Competences Threshold Resources Manchester United has a variety of Threshold Resources. Such as their stadium Old Trafford which can have around 75000 spectator to be seating in. Mu also have a huge worldwide of retail stores and Megastore to sell their product such as cloth, shoe, equipment and other which is related to the Red Devil or MU. Besides that, MU owns the Red Cafà © where their fans and customer can be enjoy food, matches and face-to-face showing wall with MUs non-stop action. MU has variety of staff line such as first team for matches, academic, coaching staff and ticketing as well. Besides that, MU financial is stable and the strong sponsor AIG on of the biggest insurance company of the world. Unique Resources MU owns a Museum which is show the greatest football club history of MUs.

Besides that, MU also has a range of value players such as Ryan Giggs, RIO Ferdinand, and Wayne Rooney and so on. Other than that, the product of MU is Unique as well like MU jersey, sport shoe and others. The strong fans club also 1 of their unique resource as well. Threshold Competences The Old Stafford stadium is the biggest stadium among all football clubs in UK. Therefore, there are more spectators can be sitting in and the revenue is higher than other football club. Besides that, the Museum is also unique for its club there is only showing of MU history and it can be an advertising method to attract more fan and consumers to purchase in. Besides that, it is not a advertising that MU paying for, instead the consumers will pay for a tour for it. Beside that, the Wider network of distributor of its retail store and megastore than others. Conclusion Manchester United is in a very competitive spot at present, nonetheless they require to be cautious that they are not getting self-satisfied and that they are focusing on the market, and the requirements of their clients and followers. By implementing the research into their markets, it will allow them to build up products for the clients, which will bring about sustained

My Personal Philosophy of Education Essays -- Philosophy of Teaching S

Philosophy of Education Education is the process of learning that can take place anywhere and at any time. I believe that creativity and activity as well as books and lessons are essential to the learning process. As a teacher, I hope to instill in the children a sense of knowledge and self-worth that will remain with them throughout their lives. Education is important not only to maintain daily life, but also to become someone who contributes to society. Without education people have no chance to impact the lives of others in their own community. I want to give the children I teach a chance to give back to their community and society. Although ethics and morals are constantly being reevaluated and argued, I hope to teach a basis of right and wrong that will stand in any religion, belief, and custom in society. While I cannot push my own morals and ethics, I think an understanding of morals allows people to be conscious of others’ feelings and to live more peacefully in society. I believe classroom management should not be strict and starchy where everyone functions like a silent, well-oiled machine. Instead, I would prefer to allow my students to take part in the rule making and decision making processes. I would also like for my students to feel free to ask questions, add to the lesson, and participate in classroom discussions without the fear of ridicule or punishment. I firmly believe in rewarding my ...

Psalm 23

Ann Lim Essay #5 In Class Poetry/Song Analysis Psalm 23 is a well known and often recited, memorized and studied passage of the Bible. It is probably one of the most cherished and treasured Psalms of Christian Religion. Even those who once attended the Church at the young age can recognize and recall Sunday School lesson of â€Å"The Lord is my shepherd, I lack nothing. † The book of Psalm consists of total of 150 poems. It is divided into 5 books: Book I (Ps. 1-41), Book II (Ps. 42-72), Book III (Ps. 73-89), Book IV (Ps. 90-106) and Book V (Ps. 107-150).The book of Psalms is written by numerous authors including King David and Psalm 23 is written by this King who reigned and ruled the Israelites with justice, and righteousness. His name is mentioned the most in the Bible and he is the most beloved King by the Israelite Nation. This particular Psalm was probably written in David’s later life as King. In studying 1 and 2 Samuel, David was the youngest son of Jesse of Bet hlehem. Though King Saul was already reigning as the King of Israel, by the command of God, the prophet Samuel anointed David as King of Israel instead because of King Saul’s disobedience and pride.However, before David was officially recognized and put on the throne, he suffered persecution and hardship from King Saul who wanted him to be dead. Because King David has relied on the Lord his God to bring him to the place of Kingship at God’s timing, he was humble and trusting in God. According to the Bible, because he was such a character, God himself has called him a man after God’s own heart. Before he was a King, he was a shepherd himself who protected and tended his father’s sheep. The Bible also notes that he was a skillful musician.Psalm 23 has been given the title, â€Å"A psalm of David. † In this psalm, David claims himself to be a shepherd who is led by God, his shepherd. The shepherd guides, protects and comforts the sheep. Good things ar e prepared in the presence of his enemies. And because this is the kind of shepherd God is, the sheep or himself shall not want anything else. And in all of his life, goodness and love will follow him and he will dwell in the house of God. King David is addressing to himself and meditating on his God, the good shepherd.He confesses about the shepherd, his Lord who leads him, who refreshes his soul, who guides him and protects him. He then switches to addressing God directly, â€Å"You prepare a table before me/†¦You anoint my head† (Ps 23:5). When the reader reads, they are able to make the same profession of trust in God and who God is, then able to speak to God, like David himself. They are able to pray and confess the same faith and assurance. Psalm 23 is a prayer of David and his conversation with the Lord, his shepherd. Many pastors and evangelist has preached of Psalm 23.Without the help of religious experts, anyone can understand and comprehend this Psalm. This sh epherd, or David’s Lord is a good shepherd, or a leader who tends the sheep with love, care, gentleness and goodness therefore I, the shepherd lacks nothing and will dwell in the shepherds house forever. â€Å"The LORD is my shepherd† (Ps. 23:1) personifies God as a shepherd. The first stanza indicates â€Å"I† the speaker as the sheep. Humans do not â€Å"lie down in green pastures,† or needs to be led â€Å"by quiet waters† nor do they need â€Å"rod and staff† to be comforted (Ps. 3:2, 4). These actions signify the speaker as the sheep and God as the shepherd. The sheep is known to be blind, needing constant attention. They do not know how to protect themselves nor do they know how to rest because they are the most anxious and paranoid animals. The shepherd in the days of David guarded the sheep with their lives. Not only does the shepherd needs to be with the sheep at all times, shepherd often had to protect them from wild animals such a s lions, or bears even if it coasted his life. This is why they carried both the rod and staff.The rod was used for protection and staff was used for leading the sheep. By personifying humans as the sheep who is blind, always needing guidance and attention shows how helpless and needy humans are. This signifies the relationship between the men and God and their need for each other. King David shows in Psalm 23 how much himself and the children of God are in need of the Lord, the good shepherd. He is the kind of shepherd who provides, who protects, who guides from â€Å"green pastures† to the â€Å"house of God† (Ps. 3:3, 6). Those who practice Christian faith are once again reminded of God’s grace when reading this passage. They are assured once again of the Lord’s goodness and love and his good way of leading, protecting and providing for them. Psalm 23 truly reflects on the Christianity because it shows the Lord as the leader and the people as follower, like sheep and shepherd relationship revealed in this Psalm. And it is God who leads his people into His presence, or the house of the Lord.

Sex offenders who come under Tier II are those offenders who are found guilty of committing such crimes that are against a minor, for example sex trafficking, bullying, transporting with the intention to get the minor involved in some criminal sexual activity, violent sexual contact, using the minor to perform some sexual presentation, asking a minor to get involved in prostitution or using the minor for pornography. Tier III sex offenders are those offenders who are found guilty of committing criminal acts of maddened sexual violence, sexual abuse, violent sexual contact against a minor below the age of thirteen or kidnapping of the minor.
