Careers in Psychology; Opportunities in a Changing World Essay

It is usually very vital for one to consider the choice of their career path very carefully. One should consider his or her interests in the career, the job market as well as their education qualifications. It is equally important for one to carefully examine the merits and demerits that come with each career option. This is the sole reason why career talks have become part of the school curriculum in many countries in the world. This paper will analyze three case studies of individuals who are about to complete their Bachelor’s Degrees in Psychology, after which it will critically analyze the options the three cases have laid on the table by analyzing the advantages and disadvantages of each. Denise is considering a couple of options; Master of Arts/ Master of Science in Clinical Psychology Master of Arts/ Master of Science in Counseling Psychology Master of Education in Counseling Psychology Master of Social Work Master of Science in Pastoral Counseling Master of Science in Counseling. Important to note is where the interests of Denise lie. She has an interest in reading research materials or findings related to children, however this interest is not that much. Denise is also not very interested in doing research work. Considering the fact that Denise has a passion in desire to counsel youth and children is not enough when deciding to choose the next degree program the best option for Denise would be a Master’s Degree in Pastoral Counseling. The merits of this program are that it is in all ways related to the interests of Denise. It would give Denise the best opportunity to counsel youth and children. The degree does not require a lot of research work, rather it r equires more of reading research work. This would by all means be the best for Denise. However, a Master’s Degree in Pastoral Counseling would be tricky if matters of spiritual faith are put in consideration. It is not clear where her faith lies. It would be unbeatably the best if her spiritual faith lies along the pastoral line, or if she had pursued a degree in theology. CITATION Tar12 l 1033 (Kuther, 2012)A Master’s Degree in Clinical Psychology would be advantageous in the sense that it has a wide job market and it is in line with the passion of Denise. However, this degree would not be the best for Denise since it requires a lot of research, which Denise is not very good at. Another disadvantage of this is that it would not limit her exactly to youth and children the way she would like it, older people have psychological problems as well. A Master of Science in Counseling Psychology would also not be advisable for Denise. This degree, just like the one in Clinical Psychology would require a lot of research work. Denise does not like research work and it would be very difficult for her to excel in this program. However, it could be really advantageous in the sense that it requires reading research materials and this is one major stronghold for Denise. A Master Degree in Clinical Psychology would have the same limitations as a Master Degree in Counseling Psychology. However, she loves reading research materials on youth and children. This would favor her in the case that she chose this career path. This leaves the best option for Denise as a Master Degree in Pastoral Psychology. CITATION Rob07 l 1033 (Sternberg, 2007)It would be very difficult for Raul to change what he wanted to do all his life to something else. However, the policy when choosing career paths is always no mistakes. This is when the purpose of internship comes out very clearly. All his life, Raul has been interested in counseling psychology or clinical psychology. He should be very careful when making a choice for the nest career step. This is owing to the fact that for one to excel in a certain career path, he or she ought to have the desire and passion for it. Passion does not just grow within a day and Raul does not have much time to make a decision. However, the volunteer work that he did in the psychiatric clinic seems to have helped him a great deal. The interview that he had with counselors and psychologists seems to have opened his eyes to the real career world. It is very important for Raul to make a decision before it is late since he is about to graduate from school. The interests of Raul are very important is deciding his career path. The fact that he has a wife and children makes it very necessary for him to take a career path that would help him a great deal financially. The best option for Raul in his career path would be to pursue a Master’s Degree in Counseling Psychology. This is owing to the fact that he has interests in researc h which is very vital to the program. Moreover, counseling would give him a wider job market and would therefore sustain him financially. CITATION Don08 l 1033 (Super, 2008)Having been in the cooperate world is indeed a milestone for John in the career world. As much as he was laid off, he is way ahead of a number of individuals. His experience in the cooperate world must have equipped him with a number of skills that will help him a great deal I n future. This is considering the fact that he would love to integrate his career path of psychology with business. For instance, one of the options that John is laying on the table is Industrial Organizational Psychology. I could not agree more with John on this one. Industrial Psychology would indeed be a very good way for John to combine what he learnt in the cooperate world together with Psychology. However, John should always keep in mind that this is a competitive world. The field of Industrial Psychology is just one of the fields tha t experience a lot of competition when it comes to pursuing a graduate program in the field. However, the best advice for John would be to first of all take a professional course that is related to business or rather the cooperate world. Such courses include Business Management, Business Administration, Marketing or even Certified Public Accounting (CPA). In this way, he would be able to prove his skills in the cooperate world, not just by word of mouth or experience but by Certified Professional Courses. This, together with a Bachelor’s Degree in Psychology would raise his bar much higher. Having done any of these professional courses, John would not only be fit to pursue Industrial or Organizational Psychology but he would also be able to compete with other individuals.

Occupational Health and Safety (OH&S) in the workplace. Essay

Occupational Health and Safety (OH&S) in the workplace requires co-operation from both employers and employees to ensure that the workplace is a healthy and safe environment. Both employees and employers are required to co-operate by the rights and responsibilities that are set for them. OH&S is the safety procedures in place in every enterprise to ensure both the health and safety of each and every employee. It is the responsibility of employers, who are legally (due to the OH&S Act 1996, 2001 amendment) and morally obliged to provide a safe and healthy environment. It is also the employee’s responsibility to co-operate with employers in maintaining health and safety at work. Read more: Measures that prevent fires from starting essay Employers are required to: -Provide a safe and healthy workplace -Provide and maintain a safe system of work -Provide the required resources (safety clothing & equipment) -Provide information and training for employees to work in a safe and healthy environment -Provide a process to identify, assess and then eliminate unsafe practices and hazards -All relevant laws must be followed -Ensure that employees carry out workplace rules. In the same way, employees have the right to be provided with the above-mentioned elements from their employers. It is also the employee’s obligation to abide by these regulations. Any employee who fails to meet their responsibilities can be disciplined under award conditions. WorkCover is also responsible for safety in the workplace. They are required to conduct regular checks in the workplace to ensure that the OHS act is being followed and that hazards are kept to a minimum. In most states, workers are represented through either an OHS representative or an OHS Committee depending on the size of the enterprise. Hazards are categorised into 4 different sections; Physical, Chemical, Ergonomic and Biological. It is important to be aware that a hazard does not have to be seen for it to exist. Quite often hazards you can’t see – such as ultra violet radiation, are only appreciated when it is too late to prevent damage. Many hazards have been made known in the workplace. Some of these include:  ·Exposed wires  ·Power leads on ground  ·Equipment in walkways  ·Temperature often too hot or too cold  ·Glare from windows and lights These hazards can be fixed by ensuring that the OHS committee is kept informed of these problems, and they can then ensure that they are fixed, in cases such as exposed wires. Things such as anti-glare screens can help the prevent the glare on the computer screens, and also moving employees desks  away from the air-conditioning vent can help with the temperature problems. Another cause for concern is the ergonomic factors. People do not sit in their chairs correctly and are causing backaches and injuries. To prevent injuries you should have;  ·Feet flat on the floor  ·Knees at a 90 degree angle  ·Back at 90-100 degrees  ·Relaxed shoulders and;  ·Forearm support Employees should take regular breaks and use their workstations ergonomically so that fewer injuries occur. There are also a few more Acts such as the Anti Discrimination Act (1977) and the Sex Discrimination Act 1984 and Workers Compensation Act 1987, which are all there to protect employees in the workplace. The Anti Discrimination Act aims to protect all employees in the work environment from being discriminated against on many things such as:  ·Race  ·Colour  ·Religion  ·Gender  ·Age  ·Sexuality If an employee feels as though they are being discriminated against, for any of the fore mentioned things then they should first try to approach the perpetrator and ask them to stop. If this behaviour continues, or they feel they cannot approach the perpetrator then they should report immediately to their employer or supervisor for further action. The Sex Discrimination Act aims to protect employees from being sexually harassed by someone in the workplace. Sexual harassment is any unwanted attention in an incorrect manner, whether it be:  ·Making sexual comments  ·Making sexual gestures  ·Asking someone out on a date continuously  ·Sending inappropriate materials Again if this happens, you should approach the perpetrator and let them know how you are feeling. If this behaviour continues, or they feel they cannot approach the perpetrator then they should report immediately to their employer or supervisor for further action. The Workers Compensation Act is where employers insure workers against the possibility of suffering injury arising out of or in the course of employment. If an injury does occur the worker can apply for Workers Compensation where they can receive money to cover their losses, and to pay for medical treatment. Workers Compensation can also be paid to the families of workers who die because of a work injury. In conclusion, it is evident that co-operation from both employers and their employees is needed to ensure that the work place is a healthy and safe  environment, with the help of legislations along the way.

Headline after the discovery of the bodies of Holly and Jessica, missing 10 year olds Essays

Headline after the discovery of the bodies of Holly and Jessica, missing 10 year olds Essays Headline after the discovery of the bodies of Holly and Jessica, missing 10 year olds Essay Headline after the discovery of the bodies of Holly and Jessica, missing 10 year olds Essay Essay Topic: Bishop the Fish The Year Of the Flood Wars, earthquakes, racial violence, terrorism crowd our newspapers. No news is good news and in our society this is often the case, as just about every evening the television news brings into our homes reports of senseless murders, great injustice and events that can only be described as evil. At some point in everybodys life they will be subjected to some form of suffering, however much we feel we are familiar of that pain it still shocks and scares us when we are confronted with it. By suffering we generally mean the pain and sorrow caused by sickness, physical handicap, mental handicap, death, poverty etc.Is God really there? If he is, does he care? And if he does, is he helpless to do anything? Why does a God of love permit suffering?The dictionary describes evil as, wickedness, a force doing something which is socially harmful or morally wrong. The word evil tends to denote the baser human emotions such as hatred, prejudice, greed, jealousy, rage etc. The bible teaches us that e vil is the opposite of good and right. It is a destructive force. It is important however to distinguish between two types of evil: natural evil and moral evil. While the two however can often be intertwined, moral evil tends to be the actions of free creatures (theft, rape, murder etc) whereas natural evil is the result of a natural event (earth quake, floods etc).Suffering and evil is unquestionably one of the greatest obstacles to Christian faith. John Stott said, the fact of suffering and evil undoubtedly causes the single greatest challenge to the Christian faith. Christianitys very symbol is that of Christ suffering and dying on the cross to save us. To a Christian there is no bigger test of faith than trying to accept the fact that the God who loves them permits them to suffer at times even in excruciating ways. Why does a God allow his creatures, and even his children to suffer? There is so much pain in the world it is hard to see how a fair, kind loving God would create a u niverse with the potential for so much suffering.Where was god when 6 million Jews were slaughtered in the holocaust, when Nazi prison guards threw babies and small children into gutters of boiling human fat rather than waste time gassing them, where was God when the remains of the slaughtered were scavenged- hair cut off to stuff pillows for their killers head rests, skin dried out to make lampshades and gold tooth fillings pulled out and turned into jewellery? Where was he when, in the Ukrainian town of Chernobyl, an explosion occurred that may yet cause up to 300000 deaths and the effects of which could take up to 200 years to remove? Where is he during famines and wars? These are just a few examples of extraordinary human suffering.Christians believe that God is omnipotent. This believe however would imply that, if correct, then he must not be loving enough to use his powers to cease evil and suffering. If God were good, He would wish to make His creatures perfectly happy, and i f God were almighty, He would be able to do what He wished. But the creatures are not happy. Therefore, God lacks either goodness, or power, or both C.S. Lewis People often find themselves rejecting the word of God due to suffering.The book of Genesis in the Bible describes to us that the first man (Adam) and the first woman (Eve), lived in the Garden of Eden, a world of happiness, without fear, shame or evil. It is obvious that God did not intent for there to be suffering in the world; it was not part of his created order. He did however give humans what many would describe his greatest gift, Free will. You may eat the fruit from any tree in the garden, but you must never eat from the tree which gives the knowledge of good and evil. If you eat from that tree then you will die! Genesis 2:16-18 As you can see, God lets man decide for himself whether he should obey him, and through giving him this decision, evil entered the world, there was no suffering in the world until humanity reb elled against God. It would be the view of the fundamentalist (literal belief of the bible) and the Old Testament writers that it was due to Adam and Eve that sin entered the world.Iranaeus was the Bishop of Lyons in Gaul and lived about 125-202. His view was that God created evil. He claims that God does indeed exist, yet explains him to be responsible for the occurrence of evil as he created us to be imperfect. He believes this however to be essential as evil is the only method of creating greater good. The earth is a place for the perfection of souls before their entry into blessedness. The trials of this world are like a refiners fire; they temper, strengthen and purify our natures to fit us to dwell with God.He suggests that the reason that we have such difficulties with suffering and evil is largely due to our imbalance between our concepts of good and evil. He felt that if our concepts were more balanced then we would have created the best possible world for soul making. He d oes, however, support Gods morals in that he believes that free will could not (and would not) exist without the perseverance of evil, as many evil occurrences are a result of people acting through their own free will and without. He therefore concludes that humanity is only partially responsible for suffering.John Hick who stresses the developmental nature of life, especially human life, has further developed the iranaean argument more recently. Believing that humans are not born perfect and that perfection comes at the end of the process. Virtue is not given, it has to be achieved.St. Augustine (354-430) would completely disagree with Iranaeus argument. He believed that God did not create evil but its occurrence just serves as a privation of good. He believed that all suffering was due to humanity who had abused Gods gift of free will. He believed that the creation of evil was largely due to the fall. The fall effected all of creation and the gap between man and God was eventually made to be so big that man began to depart from God and this is where the creation of evil arose. If God is good then he is neither the author of evil, nor its helpless victim. Rather, precisely because of His goodness He chooses to co-exist with evil for a time. Augustine eventually came to the conclusion that evil must be a result of soul deciding through human free will. Aristotle (384bc-322bc) supports Augustines view, believing himself that God could not be responsible for the existence of evil. God is an all powerful and good being, and man cannot ever be to his standard, no one will ever have the same moral values as God.This all would imply that human suffering must be a cause of our disobedience. This said, how can we justify innocent suffering, natural disasters. Events in which human interference has no obvious position?Natural disasters. We hear about them often, earthquakes, floods, famines, landslides, they can wipe out thousands of innocent lives. Starvation and its related diseases causes one person per second to die. 75% of them are infants and children under 5. The suffering caused by floods, hurricanes, earthquakes etc cannot largely be blamed on other people. However its sometimes due to the mistakes of others that natural disasters happen as natures laws are stretched to their limit. Natural disasters are often called acts of God. Again many Christians believe that natural disasters are caused by the fall, a consequence of the disruption of the perfection of Gods original creation.Natural disasters are a result of disorder in creation. However, if you take time to think of a recent natural disaster, such as the Earthquake in El Salvador (Feb 2002) a 6.6 magnitude earthquake resulted in at least 315 deaths and around 3,400 people being injured we cannot begin to believe that are loving god is responsible. Nature is often seen, as it is in the New Testament as natural in Gods eyes. Hanson and Hanson would agree with the sentiments that natu ral suffering is inexplicable. The basic theory to be learned is that nature is not moral and humanity is, therefore, as our world is continually changing however much we strive we will never achieve a perfect world as the natural laws will always follow their own course. God neither allows or forbids evil, it is just part of the way the world is, an event which humanity must put up with if they choice to live on this planet.Although most see suffering as something which is painful and not at all enjoyable, some would believe that there is a reason for it, that it is a privilege, that if you are submitted to great suffering and overcome it you are fulfilled in the eyes of God, you are fit to become a disciple. Christ himself undertook great suffering on the cross to save us and many Christians believe that the suffering they undergo themselves is closely linked with the pain suffered by Jesus, We share in many sufferings of Christ. In the same way, much comfort comes to us through C hrist. If we have troubles, it is for your comfort and salvation, and if we have comfort, you also have comfort. This helps you to accept patiently the same sufferings we have 2 Corinthians 1:5Suffering can also been seen as a test of faith. It is felt but those of the Christian faith that those who are subjected to suffering will eventually be brought closer to God. It has once been said that if we as Christians cannot bear the cross then we will not wear the crown. This is in connection with the above theory of suffering being a method of making oneself fit in the eyes of God to be a disciple. There are references in the bible to how suffering my be a test by God, for example in the Old testament Jesus tests Jobs loyalty to him by inflicting suffering upon him. Job overcomes this suffering and is therefore rewarded for the pain he had experienced. The Lord blessed the last part of Jobs life even more than the first part Job 42:12. God had established that Job would stay true to hi m, even through the greatest suffering.This story of Job you would think would go some way to proving that suffering is not a punishment, as with Job, it just brought him a deeper and more meaningful understanding of God. Still however it is often viewed as a punishment, a way for God to retaliate for humanitys sin. It is common belief, especially in the Old Testament, that evil was solely created for use to punish people who went against Gods wishes. A substantial amount of our suffering is due to our own personal sin, for example, if a person abuses drink and then drives a car recklessly and injures himself then their injuries are obviously partially due to their own personal sin. However what can be said when suffering is subjected to a person who has made no obvious sins in theirs life?When pious people suffer from sickness, bereavements etc the question is often raised, what did I do to deserve this? And when children suffer, such as the disappearance of missing 10 year olds Ho lly Wells and Jessica Chapman, who were later found dead in an area near their home, how can it be possible that their deaths were a punishment for there sin? The problem with coping with bereavement also is that people tend to think, why them and not me?Much of the suffering in the world is caused by others sins however. So much suffering is caused by murder, adultery, theft, sexual abuse, unloving parents, reckless or drunken driving, slander, unkindness or selfishness of one kind or another. It has been estimated that 95th percent of the worlds suffering can be accounted for in this way. As was told with the story of Job however, the bible disagrees with this opinion, the story of job recognises that the wicked often prosper and if we are to believe that the way in which we suffer is a direct mirror of the way in which we live our lives we would be much mistaken as this would be an unfair judgement of Jobs life. God shines on good and bad alike.One of the most important counter a rguments to that of suffering being a punishment is to remember that Jesus himself suffered. He led a perfect life, and yet he still suffered an excruciatingly painful death, Our suffering is not worthy of the name off suffering. When I consider my crosses, tribulations and temptations, I shame myself almost to death, thinking what they are in comparison to the sufferings of my blessed Saviour, Jesus Christ. Martin Luther King. God can be seen to work through suffering. Those who nailed Jesus o the cross did so for evil purposes, but God intended it for good. The cross stands ultimately as a victory because it holds the key to salvation. Christians are taught not to be afraid of suffering and death, and to turn to their faith as, let not your heart be troubled neither let it be afraid for I am with you always even into the end of the world John 14.Many are unsure as to where the suffering will end. Despite all our talk of the great injustice of human suffering many people are unwill ing for it to end, live is something to be enjoyed in many cases. However the spectrum is wide in that respect as some people are faced with great injustices whereas others lead mainly trouble free lives. Will those who deserve to suffer pay for there sins after death and those who suffer innocently in life rejoice? It is the view of the New Testament that those who have not received salvation will continue to suffer after death, have to endure eternal torment. The Roman Catholic Church, however, believes that when death becomes us we will enter a period of purgatory where we will pay for our sins, but eventually will be rewarded with a life with God.It is the feeling by many Christians that whatever suffering we have to endure on this earth will be fully compensated through the resurrection. That our, light and momentary troubles are achieving for us an eternal glory that far outweighs them all 2 Corinthians 4:17. This develops the test of faith theory even more strongly as it take s great religious faith to undergo suffering and still be aware that there will be a greater glory waiting. Gavin Reid, the bishop of Maidstone, tells of a boy who shattered his back falling down a flight of stairs at the age of one and consequentially spent the majority of his life in hospital, when asked the question, is that fair, he simply stated that God had all eternity to make it up to him. The New testament is full of promises of how wonderful heaven will be, so with this knowledge, our suffering should only be making us more fit for the reward that we shall receive.So, if we choose to accept that evil does indeed exist what is it, what form does it take? The New Testament gives the impression of God being at War with evil, or more specifically, a war between the Devil and God. This dualist view that is taken by many people and by religions such as the Zoroastrians of ancient Persia, in which states that the lord of light is locked in perpetual combat with the lord of darkne ss Other religions such as Christianity, Judaism and Islam remain monistic, in that they are of the opinion that the devil is one of Gods creatures, as the Lord created all. There is a very stereotypical view of the devil, which stems from medieval time. This paints the devil as being a humorous creature with read face; horns and pitchfork but the bible would present it very differently. He is referred to often as Satan, the Hebrew word for enemy.Some would say that one of the synopsis of our sin is our desire to be as God; and wanting all the answers. When looking at the situation with suffering and evil I feel it would be a some what naive and narrow minded view to take that, because of the great suffering endured by so many people that there cannot be a god. As this existence of God is unlikely to be proved and is purely based o n faith it would be wrong to strike of any of the points discussed in this essay as invalid to the situation, all or none may be of relevance.

Make Hot Ice From Vinegar and Baking Soda

Make Hot Ice From Vinegar and Baking Soda Sodium acetate or hot ice is an amazing chemical you can prepare yourself from baking soda and vinegar. You can cool a solution of sodium acetate below its melting point and then cause the liquid to crystallize. The crystallization is an exothermic process, so the resulting ice is hot. Solidification occurs so quickly you can form sculptures as you pour the hot ice. Fast Facts: Hot Ice Science Experiment MaterialsBaking SodaVinegarConcepts IllustratedSupercoolingCrystallizationExothermic Chemical ReactionsTime RequiredFrom start to finish, this experiment takes about an hour. Once you have the hot ice, you can quickly melt and recrystallize it.LevelBeginner to Intermediate LevelNotesThe chemicals in this experiment are non-toxic. However, because liquids are boiled, adult supervision is recommended. This project is best for middle school and above. Sodium Acetate or Hot Ice Materials 1-liter clear vinegar (weak acetic acid)4 tablespoons baking soda (sodium bicarbonate) Prepare the Sodium Acetate or Hot Ice In a saucepan or large beaker, add baking soda to the vinegar, a little at a time and stirring between additions. The baking soda and vinegar react to form sodium acetate and carbon dioxide gas. If you dont add the baking soda slowly, youll essentially get a baking soda and vinegar volcano, which would overflow your container. Youve made the sodium acetate, but it is too dilute to be very useful, so you need to remove most of the water. Here is the reaction between the baking soda and vinegar to produce the sodium acetate: Na[HCO3]– CH3–COOH → CH3–COO– Na H2O CO2Boil the solution to concentrate the sodium acetate. You could just remove the solution from heat once you have 100-150 ml of solution remaining, but the easiest way to get good results is to simply boil the solution until a crystal skin or film starts to form on the surface. This took me about an hour on the stove over medium heat. If you use lower heat you are less likely to get yellow or brown liquid, but it will take longer. If discoloration occurs, its okay. Once you remove the sodium acetate solution from heat, immediately cover it to prevent any further evaporation. I poured my solution into a separate container and covered it with plastic wrap. You should not have any crystals in your solution. If you do have crystals, stir a very small amount of water or vinegar into the solution, just sufficient to dissolve the crystals.Place the covered container of sodium acetate solution in the refrigerator to chill. Activities Involving Hot Ice The sodium acetate in the solution in the refrigerator is an example of a supercooled liquid. That is, the sodium acetate exists in liquid form below its usual melting point. You can initiate crystallization by adding a small crystal of sodium acetate or possibly even by touching the surface of the sodium acetate solution with a spoon or finger. The crystallization is an example of an exothermic process. Heat is released as the ice forms. To demonstrate supercooling, crystallization, and heat release you could: Drop a crystal into the container of cooled sodium acetate solution. The sodium acetate will crystallize within seconds, working outward from where you added the crystal. The crystal acts as a nucleation site or seed for rapid crystal growth. Although the solution just came out of the refrigerator, if you touch the container you will find it is now warm or hot.Pour the solution onto a shallow dish. If the hot ice does not spontaneously begin crystallization, you can touch it with a crystal of sodium acetate (you can usually scrape a small amount of sodium acetate from the side of the container you used earlier). The crystallization will progress from the dish up toward where you are pouring the liquid. You can construct towers of hot ice. The towers will be warm to the touch.You can re-melt sodium acetate and re-use it for demonstrations. Hot Ice Safety As you would expect, sodium acetate is a safe chemical for use in demonstrations. It is used as a food additive to enhance flavor and is the active chemical in many hot packs. The heat generated by the crystallization of a refrigerated sodium acetate solution should not present a burn hazard.

Short primary source essay World War II & the post-war world

Short primary source World War II & the post-war world - Essay Example The World War II severely razed lots of civilians making it a backcloth for genocide killings. It involved the killings by Nazi Germany and other mass slaughters of non-combats. Japan did an extermination of millions of Chinese and Korean nationals. The Soviet Union also carried out mass killings internally with Allies bombing no-combatants in Germany and Japanese. The war ended with the number of dead being more than fifty million. World War II involved battles that were fought in the air, on land and at sea. Among the well documented wars are as follows; Battle of Britain (1940), Stalingrad, El Alamein (1942-1943), Battle of Bugle (1944-1945) and Iwo Jima (1945). In 1944, there was a famous D-Day landing that was considered a turning point in the event of war. It did result to deliverance of Paris, and giving room for Allied forces to draw near Germany. The years after the end of the World War II have seen a remarkable change in Europe and the entire world it once dominated. Before the war, the world was in two spheres led by an exterior power: western sphere by United States and Eastern sphere by Soviet Union. The European countries that dominated colonial empires since Renaissance did lose their power for good. It is in these years that new European initiatives like economic cooperation between countries and political unions were been formed to exceptional extents. It brought the most possessions in the European history. Though Europe’s mighty declined, its impact continues overseas. World War II did leave a power gap in Europe. Initially, Germany, France and Britain were Europe’s leaders and world’s superpowers. The weakness resulting from the World War II left them outranked by United States and the Soviet Union. The two superpowers used Europe as their ground for conflicts. There emerged a cold war between the superpowers with the first round in 1949
