The American Recovery And Reinvestment Act Essay - 799 Words

On February 17, 2009, the American Recovery and Reinvestment Act was instated. This fiscal plan was created to stabilize the economy while it was spiraling down out of control. At the time, the United States was experiencing many economic problems and was very close to a collapse. The American Recovery and Reinvestment Act was created by Barack Obama to save 900,000 to 2.3 million jobs. The plan asked for 800 billion dollars but had to be approved by congress first. This plan tried to end the breakdown of the economy and boost it back up to its normal level of performance if not better. There were many plans that was proposed to the government on solving this problem. The only thing is that most happened to be neoclassical. Most government officials feared that a long term plan would never kick, the plan would need take full effect fast enough to sustain and level out the economy for the current path that the economy was taking. So the representatives in congress chose to pass Obama ’s plan. The plan by Obama was a keynesian type of plan. â€Å"Keynesian economics is a theory of total spending in the economy (called aggregate demand) and its effects on output and inflation. Although the term has been used (and abused) to describe many things over the years, six principal tenets seem central to Keynesianism,† (Blinder) The first three describe how the economy works.

The land of Palestine Free Essays

string(25) " of the State of Israel\." The land of Palestine is considered holy for the Muslims and the Jews, the Jews consider it as the promised homeland from god. The conflict between the Israelis and the Palestinians dates back to the time of the Ottoman Empire in the 1880s. At that time, the Muslim Arabs predominantly inhabited the land of Palestine where as the Arab Christians and the Jews were present in smaller groups. We will write a custom essay sample on The land of Palestine or any similar topic only for you Order Now It was the idea of the Promised Land, which inspired the Jews to come and settle in the land of Palestine. It was in Europe where the early Zionist movement started which promoted the idea of Jews having a â€Å"state of their own† which should be in the Land of Israel (Palestine). In 1897 the World Zionist Organization was founded by Herlz â€Å"declared that the aim of Zionism was to establish ‘a national home for the Jewish people secured by public law’†¦ this idea began more pronounced among Jews and got immense support from the West because of the riots against Jews which proved murderous for the Jews . The mass killings of the Jews by the Nazis during World War II in which about six millions Jews were cruelly murdered under the rule of Hitler calling it the Final Solution of the Jewish Question. These killing by the Nazis intensified the international support for the creation of a homeland for the Jews. The Zionist movement overlooked a major factor before promoting the idea of a state in Palestine, which was that another people, the Muslim Arabs, already occupied it. More interestingly, the West and Europe also ignored this crucial problem this was due to the fact that idea of a Jewish state attracted the British for religious as well as practical purposes. It was 1917 in which the British army took control of Palestine from the Ottoman Empire and in the same year Balfour, declaration was passed which was seen as a promise made by Britain to the Jews for further increasing its efforts for a Jewish national home in Palestine. A point that is to be noted here is that after the second world war Jews made a 33% of the total population in Palestine where as in 1922 they were a mere 11%. They saw the increasing number of Jews in their homeland as a conspiracy against them and their homeland the Jews were looked upon as outsiders. They also became greatly influenced by the European anti-Semitism and adopted many ideas and claims of Holocaust deniers as well as the anti-Zionist ideology of radical Jewish intellectuals. The newly created UN suggested dividing the country into two one for the Arabs and the other part for the Jews, and Jerusalem was to be assigned as a corpus separatum meaning an international city. The Jewish community accepted the plan as they had nothing to lose, in fact they were at last achieving what they have always wanted, and the Palestinians on the other hand saw it as a division of their homeland. Shortly after this suggested UN plan, a war between the Palestinians and the Jews started in the beginning of the December of 1947. The condition worsened in January when the Arab Liberation Army and help from Egypt came in, in the form of Abd al-Qadir al-Husayni who intervened with several hundred of his men of the Jaysh al-Jihad al-Muqaddas. The Jewish authorities were funded by sympathizers in US and greatly assisted by Stalin. This war also marks the massacre of the Arabs by the Jewish army and the expulsion of about 250000 Palestinians to leave their country and take refuge in the neighboring countries. More successful Jewish offensives created a united front around Jerusalem. The Jews declared the state of Israel on 14 May 1948 exactly a day before the British Mandate of Palestine was to be expired, furthermore its immediate acceptance by the Soviet Union, the United States, and other Western countries, enraged the Arab States greatly. `Therefore over the next few days the newly created state was attacked by the combine forces of Lebanon, Syria, Iraq and Egypt, the state which has taken the right of the Arab homeland and in way this proves to be right too because it was the Jews who were the immigrants. This action was declared as an illegal aggression by the US and the Soviet Union whereas China backed the Arab cause. Volunteers from both the United States and Canada supported the Israeli army. The outcome of the war was a disaster for the Arab States and the Israeli forces not only managed to protect their territory but also expanded their holdings. In 1949 Israel signed peace treaties with the Arab states and the new borders now was 50% more than what the UN partition plan proposed. Egypt controlled the hold of the Gaza Strip and the West Bank was under the control of Tran Jordan. War resulted in the displacement of around 711,000 Palestinians from their homes, a proposed figure by the UN. Although a UN resolution was passed which allowed the refugees to return home but somehow the resolution was completely ignored which created the major Palestinian Refugee Crisis and the West too failed too respond. At last the dream of Zionism was achieved even though it marked a historic change in the state of the Jews i. e. the former â€Å"oppressed were now the oppressors† and as in the future the further killing and massacre of the Palestinians, including women and children will confirm the authenticity of the statement. Literature Review: Avi Shalaim wrote in his book, The politics of partition, 1921-1951: King Abdullah, the Zionists, and Palestine, â€Å"The clash between Arabs and Jews in Palestine is one of the deepest, gravest, and most protracted international conflicts of modern times. It is difficult to imagine more bitter enmity than that between the Arabs and Jews during the decades leading up to and following the emergence of the State of Israel. You read "The land of Palestine" in category "Papers" Indeed, the Arab-Israeli conflict has sometimes been described as a ‘pure’ conflict, that is to say one in which the interests of the two prot- agonists are completely and irreconcilably opposed. † For years now countless tragedies have been encountered on both sides, the majority of which the Palestinians have encountered which includes the ruthless killing of even children by the Israeli forces and the demolition of the Palestinian houses. The Palestinians on the other hand reply to this kind of Israeli atrocities by any available means this may include rocket attacks on Jewish settlements or suicide bombings. Palestinians are constantly trying to get this territory back by any means possible, and then come the issue of the Palestinian refugees who despite having their own homeland are being forced to live in neighboring countries because Israel refuses to acknowledge them. The international community and the UN have criticized Israel countless times on target killings and human rights violation but Israel seems adamant. The only way through this conflict as the international community or the West saw was to provide the Palestinian with a homeland and to persuade Israel to leave the Arab territories. There had been treaties and accords for this purpose over the past many years, the first prominent among them were Camp David Accords which was initiated by the President of US Jimmy Carter. The accord was agreed between the President of Egypt and the prime minister of Israel Menachem Begin. Two agreements were signed between Egypt and Israel the framework consisted of three parts. The first part outlined to establish a self governing authority in the West Bank and the Gaza Strip and to implement the UN resolution 242, which called for â€Å"the establishment of a just and lasting peace in the Middle East† to be achieved by â€Å"the application of both the following principles:†. â€Å"Withdrawal of Israeli armed forces from territories occupied in the recent conflict† and: â€Å"Termination of all claims or states of belligerency†. The second part of the agreement was concerned about the relations between Israel and Egypt. The third part defined to principles upon which Israel was supposed to improve its relations with neighboring Arab countries. Egyptian sovereignty was to be exercised on the internationally recognized border between Egypt and the mandated Palestine. The withdrawal of Israeli forces from Sinai and the use of airfields by Israel al-Arish, Rafah, Ras en-Naqb, and Sharm el-Sheikh for civilian purposes only. The right of free passage by ships of Israel through the Gulf of Suez and the Suez Canal based on the Constantinople Convention of 1888 applying to all nations. The Strait of Tiran and Gulf of Aqaba are international waterways to be open to all nations for unimpeded and non suspend able freedom of navigation and over flight. The construction of a highway between the Sinai and Jordan near Eilat with guaranteed free and peaceful passage by Egypt and Jordan; and the stationing of military forces were also agreed upon in the accord. The signing of this agreement triggered enough hatred for Sadat in the Arab world that he was assassinated as he was seen as a traitor to the Palestinian cause. Israel greatly benefited from this accord as compared to Egypt because peace on the border meant that the Israeli forces could now lower their alert level. The peace agreement was also seen as an agreement between the Israelis and the President of Egypt only because his people or the rest of the Arab world, which his assassination confirmed, did not share his views. Perhaps the most notable step in the peace process was the Oslo process in 1993, in which a framework for the future relations between the Israelis and the Palestinians were worked out. A US president, Bill Clinton this time, PLO’s Chairman Yasser Arafat representing Palestine and Israel’s Prime Minister Yitzhak Rabin representing the Israelis, again initiated this. This accord provided the creation of a Palestinian authority, which was to be responsible for the administration of territory assigned under its control. This accord also called for the withdrawal of Israeli forces from some parts of Gaza and the West Bank. Both sides accepted territorial compromise as the basis for the settlement of their long and better conflict. The Oslo accord was a great breakthrough for Israel, a number of Arab states thought about establishing diplomatic relations with Israel after PLO’s recognition of Israel. The Arab League too debated upon lifting of economic sanctions from Israel, which have been in place since the creation of Israel. Every thing changed for Israel and its neighboring Arab countries after the Oslo accord. Still after the Oslo process, the expansions of settlements continued and hence further disturbing the already worsening economic conditions. There fore creating doubts, frustration, and thereby causing a drop in the support for the Oslo agreement. The agreement has five chapters, which consist of thirty-one articles, seven annexes, and nine attached maps. The most important part of this agreement was the recognition of Palestinian Interim Self- Government Authority. The agreement also provided a safe passage of transport and person between the Gaza strip and the West Bank, it refrained each sides from any kind of hostile propaganda against each other. Palestinian Police was given the authority to be established and operate in coalition with the Israeli forces. The agreement also outlined the plan for the transfer of power from Israel to the Palestinian authorities. The agreement divided the territory into three areas Area A which was supposed to be under the control of Palestinian authority, Area B comprised both of the Palestinian and the Israeli authorities, the Palestinian was to control civilian authority while Israel continued to be in charge of security, Area C was to be under exclusive control of Israel. This process saw a downfall with the assassination of Rabin and the Likud party coming into power, which came as a serious blow to the peace process. The Likud party destroyed homes of the Arabs, confiscated their lands, started building new Jewish settlements, and opened an archeologist tunnel near Muslim Holy places in Old Jerusalem. Avi Shlaim wrote in his book International Relations of the Middle East, â€Å"That the basic reason for the failure of Oslo to resolve the conflict is that Israel, under the leadership of the Likud, reneged on its side of the deal. By resorting to violence, the Palestinians contributed to the breakdown of trust without which no political progress is possible. But the more fundamental cause behind the loss of trust and the loss of momentum was the Israeli policy of expanding settlements on the West Bank which carried on under Labour as well as Likud. This policy precluded the emergence of a viable Palestinian state without which there can be no end to the conflict. † In May 1999, the Likud party was overthrown and the Labor party came into power by a landslide victory. Ehud Barak was elected as the prime minister but Barak lacked Rabin’s vision and his style was arrogant and authoritarian and he approached diplomacy as the extension of war by other means. Under Barak’s regime the expansion of Jewish settlement which was seen as a barrier to the peace process. There fore one more agreement with this new government was needed and quite necessary because a deadlock had been created between the Israelis and the Palestinians. On July5, 2000 Bill Clinton invited Arafat and Barak to negotiate the peace process. Barak appeared believing that America would help impose his agenda in the final settlement. Barak suggested an independent Palestinian state, which would consist of the whole Gaza Strip and most of the West Bank, he also agreed for the return of the refugees that would involve 500 people a year. He agreed on partitioning of the city of Jerusalem, but the Palestinian authority refused this point because they wanted exclusive sovereignty over all Arab suburbs and over Temple Mount. The Palestinian authority was divided on the proposal some saw it as a historical breakthrough others saw it as a compromise with their national right. Further more the delegation came under pressure from Egypt and Saudi Arabia not to compromise the holy places of the Muslims. Therefore, Arafat rejected most of the proposals, the summit ended in failure, and very easily, Barak and Clinton put the whole blame of the failure on the shoulders of Arafat. The Palestinians accused Bill Clinton of siding with Barak, therefore Arafat returned home once again empty handed. According to Ken Booth and Tim Dunne, in their book, Worlds in Collision: Terror and the Future of World Order â€Å"the policy of using US moral, material, and military support to give Israel the confidence to go forward in the peace process, has not achieved the desired results. The best proof is Bill Clinton. He was, in the words of one Israeli newspaper, the last Zionist. Yet, even he could not sweet talk Israel into a final settlement. If Clinton could not do it, nobody can. That leaves only one possible path to progress: an externally-imposed solution. † [1] The failure of the Summit at Camp David started an outbreak of violence began. The violence was further sparked by the visit of Israel’s opposition leader Ariel Sharon to the Temple Mount, the site of Al-Aqsa mosque in Jerusalem. There fore the second intifada, an Arabic word for uprising, started. The Palestinians saw the Israeli-American proposal at Camp David a complete surrender to Israel’s demand, they knew that they have been malevolently duped with not even a minimal solution to the issues which constitute the Palestine question. It is against this background and Sharon’s provocative visit to Al ‘Aqsa that the Second Intifada erupted. The uprising resulted in a new wave of brutal killings from the Israeli side to stop the rebellion which included the killing of a 12 year old, the Palestinian responded by suicide bombings attack on Israeli civilians. An article in Australian for Palestine stated that â€Å"Since the Al ‘Aqsa Intifada, Israel defines the situation in the occupied Palestinian territories as â€Å"a situation of hostility† rather than a â€Å"belligerent occupation† and therefore it contends that the Hague Regulations which protect civilians under military occupation no longer apply. Furthermore, it contends that it is not responsible for compensating the Palestinians for any damage caused or any property taken. † This incident also increased the international involvement; according to a report, Israel annually receives $1. 2 billion in economic aid and $1. 8 billion in military aid from the United States, excluding loan guarantees, besides that many humanitarian groups also responded greatly after this incident. the incident also provided a significant shift in U. S policy. The Palestenian leader was now not welcomed in Washington by the new Bush adminstration, furthermore Bush called on to the Palestinians â€Å"to elect new leaders, leaders not compromised by terror†, hence clearly indicating the shift of policy towards the Palestinian leader. To maintained peace he also outlined detailed steps prominent among them were the Palestinian rejection of terrorism (suicide bombing) and an end to Israel’s settlement expansion. Haig Khatchadourian in his book, The Quest for Peace between Israel ad Palestinians, said, â€Å"Consequently, its brilliant military victories over the Arab states are bound to remain very incomplete victories so long as it clings to the land that Palestinians rightfully call their own. Only when the heavy chains binding occupier and occupied are broken, and Palestinians become their own masters, can real peace and stability in the region become more than a wistful hope. For then not just sulh but salaam should become the order of the day between the majority of West Bank and Gaza Palestinians, and Israel. † In April 2003, these detailed steps took the form of the â€Å"road map to peace. † The Palestinian elected a new leader, Mahmoud Abbas, which made both the US and Israel happy because they saw him more liberal and more importantly not as a â€Å"terrorist† as in case of Arafat. These new developments made the way for a major summit of Israeli, Palestinian, Jordanian leaders, and US but the summit proved a failure. The road map to peace aims in creating an independent Palestinian state living side by side with Israel. Israel on the other hand would accept the state and end its settlements; the Palestinian on the other hand would have to stop their attacks on Israel. The road map’s process consists of three-phase development; phase1 of the project requires the Palestinian to stop any kind of violence against Israel, which is seen as an act of terrorism by both Israel and the U. S. it urges the Palestinian to make political reforms and hold fair elections. Israel on the other hand would have to withdraw and freeze on settlement expansions. The phase2 consisted of a revival of the destroyed Palestinian economy by means of an International Conference, which will support the recovery of the Palestinian economy, which would ultimately lead to the establishment of a Palestinian homeland. This part of the plan will also concentrate upon issues like water resources, arms control, economic development etc. it would also urge the Arab states to revive links with Israel, which were before the intifada period. The third phase was the confirmation stage, a second calling of an international conference and the final status and agreement of the borders. This phase was the permanent end to the conflict. The issue of the city of Jerusalem and the refugee problem also falls in the third phase of this project. Both the sides i. e. the Palestinian and the Israel have concerns over this road map. The international community has become very much involved for resolving the Israeli-Palestinian conflict based on this road map project. A group known as the Quartet formed which consisted of representatives from the Russia, the United Nation, and the European Union, which began shaping up the international policy necessary for a peace accord. Case Study: Many amendments and revisions has been taken place to the statement which was issued by the Quartet regarding the roadmap for peace on September 17, 2002, therefore the program’s outline is changing with time seeing the international events that has taken place. As stated earlier both the Palestinian and the Israeli authorities have reservations upon the project’s various versions, which they have reported, but still some experts say based on evidence that the Palestinians are opening up and beginning to comply with what the roadmap has to offer. On the other hand, the Israeli prime minister Ariel Sharon only made empty promises and there is no evidence whatsoever that Israel would go ahead with the plan. In the October of the same year, the American President Bush amended and issued his version of the roadmap, which was more detailed than the previous version and was based on the input, which he received from the Israeli and Palestinian authorities. The key reservations from the side of the Israeli government is the issue of terrorism i. e. how will the Palestinian authorities act if the terrorist activities continue and would the Palestinian government be able to handle the terrorism. The Israelis feel that this roadmap for peace may fail due to the same reasons which were responsible for the failure of the Oslo process i. e. many agreements were made but nothing were done to implement them effectively. The Palestinian authority on the other hand has accepted the plan but has not implemented the key requirement of the plan, which was to put an end to terrorist activities. Likewise, the Israeli government later agreed with the plan but made fourteen reservations on the plan and like the Palestinian authority has not implemented the crucial step of the first phase, which was to freeze all the activities relating to the settlement activity and the removal of illegal check posts from the Palestinian territories. The effect that the Iraq war has on the roadmap for peace or the Israeli-Palestinian conflict in general is immense. Due to the failure of the Bush policies in Iraq and the loss of thousands of innocent lives has made President Bush’s policies regarding Iraq a target for much criticism. Furthermore, these policies have created a feeling of great hatred among the Muslims of the world against these policies and the West in general, because of which terrorist organizations like Al-Qaeda take advantage and recruit and brainwash these already angry Muslims. Therefore, to redeem his position in the eyes of the world and especially among the Muslim world peace in the Middle East seems the best option available. Therefore, the Bush administration has to come up with options that will be acceptable to both the sides and if proposed properly Israel may accept the roadmap as being under pressured from the Quartet. Israel has faced a lot of criticism from the international community when it comes to human right violation, which has left Israel vulnerable so the Quartet could impose a roadmap on it. In 2004, Bush presented the roadmap with two significant changes as a part of the new American policy for the roadmap, and expected a final outcome of the conflict. The Israeli leader Ariel Sharon readily accepted the newer version of the plan as the two changes that Bush made seemed favored Israel a lot. The first change was on the issue of borders, which Bush suggested that it would be unwise for Israel to go back to the borders as in 1949. The second issue was of the Palestinian refugees, for which Bush stated that: â€Å"It seems clear that an agreed, just, fair and realistic framework for a solution to the Palestinian refugee issue as part of any final status agreement will need to be found through the establishment of a Palestinian state and the settling of Palestinian refugees there rather than Israel. † So no final agreement was reached. The same year saw the demise of Arafat which the US saw as a significant moment in Palestinian history. Abbass was elected in january 2005 and was invited to the white house hoping for a breakthrough atlast in the conflict after Arafat’s death who was regarded as a terrorist by the American authority. The summer another wave of voilence erupted between Palestinian and the Israelis and faded the hope for a peaceful outcome. The same year in August the world saw the withdrawl of Israeli forces and settlers from the Gaza strip and the West Bank, the withdrawl was initiated by the Israeli prime minister ariel sharon, who also left the Likud party joined a more moderate one. The withdrawl was heavily appreciated all around the world and the international for once saw a ray of hope amidst the darkness of the bloody conflict. In January 2006 Sharon got a massive heart stroke and retreated from the party , the same month saw the Palestinian ruling party Fatah got defeated by Hamas, a group which the USA had labeled as a terrorist organisation long ago. Hamas has always held the views for the destrution of Israel. Therefore immediately after the Hamas’s victory USA and Israel called for the financial and the diplomatic isolation of the new Palestinian government and this also put an end to any more peace talks with the Palestinian government because both Israel and USA refused to recgnise Hamas in the government. Ehud Olmert succeded Sharon in the elections of May 2006 as the prime minister of Israel, who promised the completion of the withdrawl of Israeli forces from most of the parts of the West Bank by 2010. in the same year fresh clashes started between Hamas and the israeli forces in the Gaza strip. In the same year Israel clashed with Hezbollah in Lebanon and suffered casualities and upon admitting defeat withdrew its forces from Lebanon. This conflict had an important impact on the road map and many interpreted these clashes as an end to the roadmap peace process. In the October of the same year an Israeli news paper revealed that the government was still developing new settlements in the West Bank, even though Olmert promised the withdrawl and the removal of the settlements. Many of these settlements were being made on Palestinian property that even the Israeli government recognise as being theirs. For a fear of a political crisis with the USA and for the fear of being criticised by the international community , the report was kept a secret. The situation of the Middle East was worsened by civil clashes between the two major Palestenian groups Hamas and Fatah. Whether or not the Roadmap for Peace succeded or achieved its desired results or outcomes is really hadrd to tell because the success or the failure of the project solely depends on how sincerely both the parties work for the restoration of peace making sure that their ideologica differences do not interfere with the peace plan. The international community have countless times tried to maintain peace between the two sides by proposing a solution which would be acceptable to both the parties, but every time due to some reason or the other the peace process seems to end with completion possibly because the terms and the conditions of the proposed agreements were not suitable for one of the party or during the peace process a deadlock creates due to clashes or hostilities e. g. the second intifada. The Roadmap for peace plan guaranteed the creation of an independant Palestinian state wxisting side by side with Israel in peace, it also promises the Palestinians that Israel will withdraw its troops and freeze the building of its settlements on Palestinian territories. So far nothing of this sort has happened so baically the roadmap as I see it has failed because it failed to provide what it promised to the Palestinians and the Israelis. The Palestinians still have to live under a constant threat of being attacked or even killed by the Israeli forces anytime, not even the children are safe. The Israelis have to face the Palestinian revenge when some loved one of theirs die in a suicide attack. Both sides have endured countless casualties mostly civilians and the innocent people. Further more the building of the wall around the Palestinians have complicated issues even further and has restricted the Palestinians to a limited area of land only, there are only two openings and travelling to the world outside the wall is not possible air, sea or land. It is seen as another illegal attempt tocapture Palestinian land. The international community have proposed many proposals inaddition to the ones mentioned above but all of them have not proved any useful. USA has been playing the role of an initiator of peace talks between the two authorities for many years now, but as USA is a close ally of Israel and have political advantages to reap from Israel, the muslim world in general see the sfforts being made by the American government as inefficient or being biased and always in the favor of Israel. They feel that it is in the power of the American government to force Israel out of Palestenian areas and to make Israel stop the killings of the innocent but still America is reluctant to do such a thing and make peace in the region. The United Nations too has passed many declaration agaisnt the violations of human rights, which includes the killings and the destruction of homes of the Palestinian, by the Israeli government but Israel has never taken any heed. The united nations has also passed a number of resolutions against the barrier and the International Court of Justice has also issued an order which describes the barrier as illegal an orders to be stripped down . Israel on the other hand has ruled out the decision of the International Court saying that it did not considered the court’s jurisdication. In a 2004 report Amnesty International wrote that â€Å"The fence/wall, in its present configuration, violates Israel’s obligations under international humanitarian law. † The world council of churches has also condemned the barrier saying that it is a serious violation of human rights and humanitarian consequences owing to the construction of the barrier. Some international governments do support the Israeli actions but still oppose the barrier as it is built outside the 1949 armistice lines. Conclusion: The conflict between the Israelis and the Palestinians have been going around for decades it has not only sabotage peace in that particular region but has also effected the neighboring countries as well. The conflict has created many problems and many enemies for the state of Israel. Many people think Israel as an illegal state which donot have the right to exist, where as there are a group of people which agree the right of Israel to exist as a nation, as a state but not at the cost of the annexation of Palestinian land and not by the killing of the Palestinian. The Roadmap for Peace, even though has been accepted by all the sides but still has done little to promote peace in the region because no sincere efforts have been made to implement the plan. However over years of negotiations the RoadMap remains the only alternative that leaders from both the sides have agreed upon , whereas agreements like the Geneva initiative still has a long way to go before it is officially accepted by the leaderships of the two parties. Many experts view the geneva accord as a better means of promoting peace among israelis and the palestinians because the accord provides many realistic solutions to problems which have been evaded in the past agreements. An article in the Israeli news paper commented that Tel Aviv Ma’ariv (Israeli, Hebrew-language, centrist), April 22: The Israeli-Palestinian conflict today isn’t just a conflict between leaders and worldviews, it is a conflict between two peoples filled with bitterness and hatred, between parents and children who have lost many of their relatives and their belief in peace.

Identification and Strategies Description System †MyAssignmenthelp

Question: Discuss about the Identification and Strategies Description System. Answer: Introduction Strategic management is the identification and strategies description that can be used by managers in order to achieve a competitive advantage and better performance for their organization. For an organization to be said to have a competitive advantage, its profitability should be higher than average profitability of other companies in its industry ("Strategic Management - Meaning and Important Concepts," 2017).In this report, a research was carried out using the method of CESIM simulation game. There are different groups divided to carry out same research expecting a different result. Working with group RED, the study was based on a telephone company with markets for its products in Asia, Europe, and the USA.The objective of the research carried out by group Red, was to look at the overall corporate strategy .what does the company plan with a long-term focus. Strength, weakness, opportunity and technology analysis is to be conducted in the various mixes such as production. Another o bjective is to look at how the organization plans to develop and deploy its strategy through development of a policy on each of its strategic units. Strength The company has employed a prosperous low production cost in Asia and hoped to imitate that success in the USA. Weakness With the little production cost in Asia and Europe, this impact on the inflexible production schedule. The success of low cost of approach is dependent on the full utilization of capacity to reduce cost. Across all rounds, there is no production cost in Asia and Europe Opportunities The company opportunity comprises of seizing the market share from Asia and Europe, through the incorporation of cost yet efficient trade strategy in Asia and Europe. The implementation of its low production strategy has brought about so much success in the USA. Threats With the small cost production in Asia and Europe, the company poses a high risk in the USA market share. Strength In round 1 in Asia, the company placed more focus on marketing with a target of reaching a broader audience for the product. In Europe in round 1, the company also emphasized the marketing of the product; the aim was to achieve the targeted market segmentation creating more awareness of the product. Weakness In round 1, there is the low purchase of the product, the sales revenue globally was little, this can be associated with the similar product with our competitors, and lack of marketing expertise. Opportunity With the increase in the money used for marketing. Use of internet for digital marketing is highly targeted. This will create more awareness globally. Threat Superior channels used by a competitor for distribution poses a significant threat. Strength Globally in round 1, the logistic and tariffs are considered low but progress across the rounds whereby, in round 5 it is considered very high. These increases in expenses show the rapid delivery of products across the countries to potential buyers. Weakness In the USA the transport and costs are recorded as zero across all the rounds. This shows the stiff competition faced by the local producers and the market share that is limited. Opportunity With the high presence across all rounds in the global market, this provides the company with a strong base to offer comprehensive services. Threat The complex law stricter of some parts of business market poses a significant threat. The company is likely to suffer from an unpredictable increase in logistic cost with the undetermined rise in fuel rates. Strengths Across all rounds in the USA there is no income tax experienced, this shows that the business working overhead and expense lead to high-profit margin. Weakness N round 5 globally the company suffered high-income tax, its progress in round 1, with the high season for business, this is regarded as weakness. This is because the business requires long working hours, but it has limited working hours, however making the business hard to retain skilled staff within the short notice of tax season. Opportunity The business should embrace the telecommuting opportunity for its staff to cut down the overhead cost. Threat With the growth of technology, the software has emerged to help solve the tax queries without any fault. Strength In the USA the business incurs low production cost; this has a positive impact on the financials of the company. Weakness In Round 1 globally, there is a small sale of products this shows that the financial of the business are low. Opportunity The company should consider reducing on the interest loans from the corporations that it borrows from loans. Threat Products from the competitor of low prices pose a threat to the business. Strength Globally, there is an increase in R$D amount, in Round 2 there is the experience of lowest and round 5 highest cost in R$D.This can be linked to the strong market growth and expertise and technical efficiency. Weakness In Asia and Europe, there is no cost incurred in RD; this shows lack of emerging competitors and rapid advancement of technology in niche markets. Opportunity Globally, in round 5, there is an opportunity for new development in communication technologies. Threat Conflict of interest posed a great threat to the business. Importance interest in the financial that affect the design. Porters generic strategy is a model of five forces that try to define policy as taking the act that creates high position in business to outperform competitors. Cost leadership. It implies having a low per unit cost of a product than the competitors. In this case, the returns will be low, but the business will stay ahead of competitors. Differentiation. It implies that the business comes up with a product that is different from those of the competitors. This can be achieved through the brand image that is unique, the various designs that create a uniqueness of the product in the industry. While carrying out the study, the porter's generic strategy that was used by group red was cost differentiation. In round 2, the company had the least price across its business units, product demand was high, and sales were also high. In round 3 the company had the highest price than competitors. The company recorded least sales. In round 5, the company had the least cost than the competitors; many units were sold as demand was relatively high. The group chose cost differentiation strategy as its objective was to stay ahead in competition although attracting low returns. Long term objectives. The business long-term objectives are to grow annual revenue and increase the marketing and strategy for public relations. Short term objectives. The global market share has increased; from 5.07 in round 1 to 12.59 in round 5.this is with the increase in sales revenue. Short-term financial objective. The short term purposes of the business are to purchase financial resources at a low price hence incrementing the shareholder's returns regarding earning. This can be achieved through reduction of money borrowed from the lenders. This is observed in the shares equity increase in round 5 from round 1 globally. Long-term financial objectives. The long-term objectives of the businesses to increase the shareholder's equity. In round 1 the shareholder equity was low, and upon round 5 the shareholder equity was raised. Selection the right strategy was significant for the business. The approach selected for use was cost leadership and niche strategy. The market in Europe was given a cost leadership, and it experienced high sales of products this is because consumers will purchase products of the low price but satisfy their needs. The niche strategy was used into segment different market share. Globally we experience the increase in market share from 5.03% in round 1 to 21.29% in round 5 Recommendation Recommendation for production. The market in Asia and Europe should not have any production cost, but minimum as this will cause an inflexible production schedule. The market in the USA should have the strategy to counter the risk posed by low production cost in Asia and Europe. Recommendation for marketing. The company should find a suitable way for distribution of products to overcome the significant risk posed by competitors. The brand image and differentiation of product from competitors should well state during marketing. Recommendation for finance. The business should embrace low price but cost leadership for the products Recommendation for RD. The company should embrace technology and new research development. The technology will improve the operation of the business and bring about the competitive advantage for the industry Recommendation for logistics and tariffs. The company in the USA should search for foreign markets and produce products that satisfy customers and increase the need for the product. Recommendation for tax. The company should embrace technology software used to auto compute tax during business operations; this will cut down on some overhead cost and improve the returns. Conclusion Through this learning, I have been able to learn more about business strategy for a successful business operation. The game is more fun to be used as a learning technique. The game has expanded my research skills and broadened my knowledge about different products in different markets, the factors inhibiting sales of various products in some markets. The activity has enabled me to learn more about the short term and long term objectives of the business. I can now clearly differentiate the short term from the long term of the objectives. And the factors to consider. This learning experience has expanded my knowledge on the use of technology software in calculating the tax .the integration of technology in the business process has enabled the reduction of overhead cost. As opposed to the manual calculation of accounting part of business operations, the automated version of accounting is accurate. References Strategic Management - Meaning and Important Concepts.

Joan Of Arc Essays (2112 words) - , Term Papers

Joan Of Arc Joan of Arc (From Harper's Weekly, 1896) The historical novel is one of those flexible inventions which can he fitted to the mood or genius of any writer, and can be either story or history in the proportion he prefers. Walter Scott, who contrived it, tested its elasticity as fully as any of the long line of romancers who have followed him in every land and language. It has been a favorite form with readers from the first, and it will be to the last, because it gives them the feeling that to read so much about people who once lived and figured in human events is not such a waste of time as to read of people who never lived at all, or figured in anything but the author's fancy. With a race like ours, which always desires a reason, or at least an excuse, for enjoying itself, this feeling no doubt availed much for fiction, and helped to decide the fate of the novel favorably when its popularity was threatened by the good, stupid Anglo-Saxon conscience. Probably it had the largest share in establishing fiction as a respectable literary form, and in giving it the primacy which it now enjoys. Without the success of the monstrous fables which the gentle Sir Walter palmed off upon his generation in the shape of historical fiction, we should hardly have revered as masters in a beautiful art the writers who have since swayed our emotions. Jane Austen, Miss Edgeworth, Hawthorne, Thackeray, George Eliot, Mr. Henry James, might have sought a hearing from serious persons in vain for the truth that was in them if the historical novel had not established fiction in the respect of our race as a pleasure which might be enjoyed without self- reproach, or as the sugar of a pill which would be none the less powerful in its effects upon the system because it was agreeable to take. It would be interesting to know, but not very pertinent to inquire, how far our great humorist's use of the historical form in fiction was prompted by love of it, or by an instinctive perception that it wa s the only form in which he could hope to deliver a message of serious import without being taken altogether in jest. But, at any rate, we can be sure that in each of Mark Twain's attempts of this sort, in the Prince and the Pauper, in the Connecticut Yankee in King Arthur's Court, and in the Personal Recollections of Joan of Arc, he was taken with the imaginative -- that is to say, the true -- nature of his theme, and that he made this the channel of the rich vein of poetry which runs through all his humor and keeps it sound whether it is grotesque or whether it is pathetic in effect. The first of these three books is addressed to children, but it is not children who can get the most out of it; the last is offered to the sympathy and intelligence of men and women, and yet I should not be surprised if it made its deepest and most lasting appeal to the generous heart of youth. But I think that the second will remain the enduring consolation of old and young alike, and will be ranged in this respect and as a masterpiece of humor beside the great work of Cervantes. Since the Ingenious Gentleman of La Mancha there is nothing to compare with the Yankee at the Court of King Arthur, and I shall be very much disappointed in posterity if it does not agree with me. In that colossally amusing scheme, that infinitely suggestive situation, the author was hampered by no such distinct records as he has had to grapple with in his Personal Recollections of Joan of Arc. He could launch himself into a realm of fable and turn it into fact by virtue of his own strong and vivid reality while in a scene whose figures and events are all ascertained by history his fancy has had to work reversely, and transmute the substance into the airy fabric of romance. The result will not be accepted without difficulty by

Multi-cultural Teams & Their Leadership Essay Example | Topics and Well Written Essays - 1000 words

Multi-cultural Teams & Their Leadership - Essay Example This paper aims to highlight the major issues that may hinder the success of such a team. Communication barriers are the first issue which may hinder the success of a multi-cultural team. The Swiss culture is said to have a bilingual culture where French, German, Romansh and Italian are said to be the official languages. However, the point of debate is the expertise of people in speaking and understanding all these languages. The Swiss culture, hence, lacks communication ease and conformity with all people in an organization or a group. Moreover, there are certain words like â€Å"achievement, commitment, common sense †¦management and skill† which lack corresponding vocabulary in German language. Thus, there is also a possibility of miscommunication and misunderstanding due to the language differences in a culturally diverse team. To overcome this barrier, the leaders and organizations may approach a language learning and training program for the workers. Moreover, the us e of soft facial expressions, appropriate tone of voice and continuous reminders of the important tasks may help in reducing the risks associated with the language and communication barrier (Adler 1997). Another problem which the multicultural group of workers can face is on reaching a common consensus. These people belong to different backgrounds and may have different perspectives on different issues. Thus everyone has his own views and they find it difficult to reach a conclusion on deciding upon certain things. These workers tend to be from a diverse background and disagree on many issues. Multicultural teams have to be managed properly so that they do not face difficulties when reaching this common consensus. These multicultural teams might be facing the problem of miscommunication and the manager should look after this. It is necessary that the manager helps the team to reach a common consensus by providing each and every worker with the necessary information about the other. The perspectives of the diverse workers are laid together so that every worker can understand it and follow the action plan. Members of a culturally diverse workforce tend to lack trust in each other than the members of a homogenous workforce. The reason for this is the diversity in the workforce that comes along with the people of different culture. The team in the superstore is related to all American, Swiss, Italian and German culture and the problem can start when one group of workers consider the other inferior. Lack of trust can occur when the Americans consider the people from other cultures to be inferior to them in terms of education and lifestyle. Similarly the people belonging to the Swiss culture would be more acquainted with the policies of the stores and hence might consider the other people inferior. It is here that the role of the manager comes into play to help them collaborate with each other. Trust can be reinforced if the managers provide the workers time to know each other. The workers should be made to work with each other so that they can get a grasp of each other’s culture. Halverson and Tirmizi (2008) put forward that trust is a major factor which helps the team members to define the role of each other. Hence it can be concluded that trust is a major factor which can help the multicultural workers to get together. Jealousy is also one of the problems that the workers in a multicultural force

Examine critically the nature and lasting impacts for domestic Essay

Examine critically the nature and lasting impacts for domestic business environment of the global financial crisis of 2007 - Essay Example Johnson et al (2008, p.55) identify the PESTEL framework as a means of analysing the environment. Following the corporate scandals of Enron and WorldCom, several commentators have added ethics to the list of analytical factors and it is this approach that will be used to analyse the macro-environment of the UK following the global financial crisis of 2007. The STEEPLE framework considers the Socio-cultural, Technological, Economic, Environmental, Political, Legal and Ethical factors that affect business and over which business has no control. An analysis of the current environment is as follows: Figure 1: Macro Environmental Analysis Although this analysis is brief, it provides insight into potential problems facing the UK in the short- and medium-term in different areas. Some of these will be evaluated in more detail. Socio-Cultural Factors Factors within this area tend to be long-term trends, such as the changing pattern of work and women’s participation in the labour market . Following the UK general election in 2010 and the change of government, there has been a significant shift in the approach to the public sector and state support for the country’s population. ... The OECD are reported as stating that the cuts â€Å"risked derailing economic recovery† (ibid), with the IMF highlighting that unemployment levels will increase dramatically, leaving many people facing a significant reduction in their â€Å"livelihood, security and dignity† (ibid). They also highlight that following job losses, people suffer from health problems. Children of parents without work do worse in school and overall â€Å"faith in public institutions and democracy† (ibid) is reduced. The previous year, the OECD has predicted a â€Å"full-blown social crisis† following the expected rise in global unemployment (Seager, 2009). The OECD secretary general was reported to have said that: â€Å"restoring global growth is an economic and political priority but also an ethical, moral, social and human imperative. And employment and social policies are an essential component of a successful strategy to bring .... countries back on a growth track† ( Seager 2009) This demonstrates that the different elements within the macro-environment are interrelated and cannot really be separated as this analysis suggests. The over-riding fear in the social domain is an increasingly polarised society with the haves doing much better and the have-nots being pushed into poverty as unemployment increases and welfare benefits are cut (Armour 2010). Technological Factors Technology includes not only information technology but the processes by which manufacturers and service providers create and deliver their products. Although the biggest impact in the technology area has been the increasing power and availability of computing power, the impact for manufacturing should not be forgotten. Most homes in the UK now have access to a personal computer and the internet, allowing them

Transformer Assignment Essay Example | Topics and Well Written Essays - 1000 words

Transformer Assignment - Essay Example A simple way to remember it is the Left Hand Thumb rule. If we grasp the conductor in our left hand with our thumb extended in the direction of current (from –ve to +ve), our finger will point in the direction of magnetic lines of forces. When two or more current carrying conductors are placed parallel to each other in a way that the direction of current is the same in all of them, as shown in Figure 2, then the magnetic lines of forces aid each other to combine and strengthen the magnetic field further. If the two conductors so placed have current flowing in opposite direction then the magnetic lines oppose each other to deform and weaken the magnetic field. The magnetic field around the conductor exists at points along the length of the conductor. When the conductor is wound in the shape of a coil, as in Figure 3, then magnetic field around each turn of the coil is aided and strengthened by the fields of adjacent turns in the coil. The resultant is a magnetic field resembling a bar magnet with one end as North and the other as South of the magnet. When the direction of current is reversed it causes the direction of magnetic field to be reversed. If we grasp the coil with our left hand with our fingers pointing in the direction of current, as in Figure 4, the thumb will point in the direction of magnetic field. Conversely, to what we have discussed till now, if a conductor is placed in a magnetic field and there is a relative movement between the field and the conductor, an electromotive force (emf) is induced in the conductor. This effect is called electromagnetic induction. Both of these phenomenons, of creating a magnetic field and then utilizing electromagnetic induction form the basis of transformers. At one end alternating current (AC) is passed through a coil, this gives rise to a magnetic field which spreads out and subsides with the same frequency as of the AC applied. This changing magnetic field in fact is a replacement to moving

Effect of Synthesis Temperature on Nickel-Cobalt Hydroxides

Tel. +86 22 60204909. Email:[emailprotected] Abstract   Ãƒâ€šÃ‚   A facile one-step method for preparing nickel/cobalt layered double hydroxides (Ni/Co LDH) in a mixture of NH4Cl/NaOH solutions in the temperature range 45-85 oC is introduced. Ni/Co LDH consists of ultrathin nanosheets of various thicknesses assembled into porous nanostructures/microspheres. The mixed solution provides OH, whose amount depends on the temperature, for reactions with Ni2+/Co2+ leading to the formation of hydroxides. The sample prepared at 70  °C shows the highest capacitance of 1142 F g-1 at a current density of 0.5 A g-1.That capacitance decreases about 15 % to 970 F g-1 at a high current density of 10 A g-1. The temperature effect on the arrangement of microsphere is apparent and Ni/Co LDH prepared at 70 oC has the most defectless texture (microspheres). The asymmetrical supercapacitor consisting of this sample as an anode and an activated carbon (AC) as a cathode works in a broad potential window from 0 to 1.6 V. The energy density of the Ni/Co of such a system reaches 58.13 Wh kg-1 at the power density of 160 W kg-1 owing to the intersectional nanosheets and unrestricted accessibility of electrolyte to the reaction centers. Even at a high discharge current density of 2 A g-1, the energy density still remains at 45.78 Wh kg-1 with a power density of 1600 W kg-1. Keywords: mild temperature, layered double hydroxides, energy density, asymmetric supercapacitors. 1. Introduction Nowadays, the development of efficient supercapacitors with high energy density is of paramount importance [1, 2]. Generally, supercapacitors can be classified into electrochemical double layer capacitors and pseudocapacitors [3]. In theory, pseudocapacitors exhibit a higher capacitance and energy density than the double layer capacitors. The latter stores electrical charge mainly at the electrode/electrolyte interface. However, the energy stored in supercapacitors is about 10 times smaller than that in batteries. This severely limits their applications where a high power density is required [4]. Therefore, there is a need to develop and to explore the advanced performance electrode materials for their applications in energy storage devices. Layered double hydroxides (LDH), especially Ni/Co LDH compounds, are considered as materials of promising properties when applied in supercapacitors [5-7]. In their structure Co2+ can be oxidized to conductive CoOOH during redox reactions resulting in the improvement in conductivity of electrode materials [5]. For instance, Ni/Co LDHs hollow microspheres obtained in SiO2 templates exhibited the specific capacitance of 2171 F g-1 at the current density of 1 A g-1 [6]. Another examples are ultrathin NiCo-based LDH prepared at 120  °C, which displayed remarkable specific capacitance of 1537 F g-1 at 0.5 A g-1 [5]. It is important to mention that Ni/Co LDH referred as hydrotalcite-like compounds allow the intercalation of negatively charged anions within the interlayer space [7, 8]. This is expected to enhance the capacitive performance. Thus Lee et al. synthesized ÃŽÂ ±-Ni(OH)2 through exchange of intercalated dodecyl sulfate anions by smaller anions (Cl, NO3, OAc and SO42-). They found that larger anions hindered the mobility of OH ions toward the surface of Ni(OH)2 sheets and Cl intercalated Ni(OH)2 exhibited excellent capacitance. Especially, the Cl ions located in the interlayer space were found as increasing its hydration level and thus enhanced the facile exchange and transport of OH ions [9]. Hu et al. reported the effect of intercalated anions on the size of an interlayer spacing, morphologies, and capacitive performance of four different ÃŽÂ ±-cobalt hydroxides. Their results showed the Cl intercalated sample as the one of the marked capacitance. The good performance was linked to its high proton affinity [10]. In this work, we introduce a wet chemical approach to prepare Cl intercalated Ni/Co LDH. The synthesis is done below 85 °C, which is the lower temperature than those reported in other hydrothermal methods [11, 12]. In designing the method, it was expected that OH ions from the solution of NH4Cl/NaOH will reacts with Ni2+/Co2+ to generate Ni/Co LDH. An important aspect is that the amount of the released OH ions should be affected by the temperature. Thus the synthesis temperature is a factor, which we expect to govern the nanosheets assembling process and thus the final morphology of the materials. The effect of that morphology on capacitive behavior is investigated. 2. Experimental 2.1 Preparation of Ni/Co-LDH microspheres All reagents were of analytical grade and were used without further purification. In a typical synthesis process, 3.75 mmol of Co(NO3)2 ·6H2O and 3.75 mol of Ni(NO3)2 6H2O were dissolved in 20 ml of water to form a pink solution (Solution A). 40 mmol of NH4Cl was added in 0.076 mol L-1 NaOH (180 mL) to form a transparent solution (Solution B); Then, the solution A was poured into 180 ml of the solution B with the final pH value of 9, in which the metal hydroxide mixtures were obtained. After stirring for 5 minutes, the solution was sealed in a glass bottle and transferred into an oven kept at a predetermined temperature (40, 55, 70 and 85  °C) for 15h. After cooled at room temperature, the obtained Ni/Co-LDH samples were washed with ethanol and water several times and dried in an oven at 60  °C for 12 h. The samples are referred to as Ni/Co LDH-x (x represents the reaction temperature of either 40, 55, 70 or 85  °C). 2.2 Characterization methods X-ray diffraction (XRD) patterns were measured on a Bruker D8 Advance diffractometer operated at 40 kV and 40 mA, Cu KÃŽÂ ± radiation source (ÃŽÂ »Ãƒ ¢Ã¢â‚¬ °Ã‹â€  0.154 nm) was used. Fourier transform infrared spectroscopy (FT-IR) experiments were carried out on Bruker Vector 22 infrared spectroscopy in the range of 400 to 4000 cm-1with KBr tablets. Scanning electron microscopy studies (SEM) were performed on JSM-6490LV field emission scanning electron microscope. The sample was dispersed on the conductive tape fixed on the aluminum support. Transmission electron microscope (TEM) analysis was performed on a FEI Tecnai G20 microscope at 200 keV. The elemental analysis of as-prepared powder carried out using X-ray fluorescence spectrometer (XRF, CIT-3000SL). 2.3 Electrochemical tests To evaluate the electrochemical performance of the synthesized materials, thee Ni/Co LDH samples were mixed with acetylene black and polytetrafluoroethylene (PTFE) in a mass ratio of 75:20:5. Homogeneous pastes obtained in ethanol were coated on a nickel foam substrate. The coated nickel foam was then pressed at 10 MPa and the obtained plate was used as a working electrode after dried at 60  °C for 12 h. The cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance (EIS) of the as-obtained samples were carried out on a IM6 ZENNIUM electrochemical workstation in a three-electrode cell. The mass of working electrode was about 8 mg. The capacitance was measured in 6M KOH electrolyte using a platinum wire as a counter electrode and Ag/AgCl as a reference electrode. EIS tests were conducted in a frequency range from 100 kHz to 10 mHz with alternating current oscillation of 5 mV. The electrochemical performance of an asymmetric supercapacitor was invest igated in a two-electrode cell of coin-type (CR2025), in which the prepared materials were used as a positive electrode and activated carbon- as a negative electrode. The experiments were carried out on the Land-CT2001A battery system in the potential range from 0 to 1.6 V. 3. Results and Discussion 3.1. Characterization of materials The typical powder X-ray diffraction (XRD) patterns provide the information on the degree of crystallinity and the crystal structure of the Ni/Co LDH materials (Figure 1a) The distinct characteristic diffraction peaks on XRD patterns at 2ÃŽÂ ¸ 11.1, 22.2, 33.4 and 38.5 are indexed as (003), (006), (009) and (015) plane reflections of the hydrotalcite-like LDH phase, respectively [11, 13]. Increasing the reaction temperature leads to a slight increase in the intensity of the diffraction peaks. According to the Bragg equation, the calculated interlayer space of Ni/Co LDH is 0.79 nm. Ma et al. reported that the layered transitional metal hydroxides nanocones displayed a variety of interlayer space sizes depending on the kind of intercalated ions [12]. The values were 0.8 nm for NO3, 0.92 nm for ClO4, and 0.79 nm for Cl. Our results suggest that Cl ions are present in the interlayer space of the synthesized ÃŽÂ ±-phase compounds. FT-IR spectra of all samples are presented in Figure 1b. The broad band at about 3449 cm-1 is characteristic of the stretching vibration of hydroxyl groups hydrogen-bond to H2O [1]. The band at about 1630 cm-1 represents the bending mode of water molecules [10]. For all samples, three bands at 1476, 1349 and 854 cm-1 are linked to the typical features of carbonate ions [14]. Their presence is linked to the reactivity of hydroxides with atmospheric CO2. Bands below 800 cm-1represent stretching modes of metal-oxygen in the hydrotalcite-like lattice [1]. The band at about 649 cm-1 is assigned to Ni-OH bending. The absorption band at around 514 cm-1 represents the Co-O stretching vibrations [15]. The results indicate that the synthesized materials are nickel and cobalt layered double hydroxides. Scanning electron microscopy (SEM) was used to analyze the morphologies of the obtained Ni/Co LDH materials prepared at different temperatures. Figure 2a shows a typical SEM image of Ni/Co LDH-40. There microspheres with a size around 3 ÃŽÂ ¼m and a small amount of aggregated nanosheets is visible (Fig. 2a inset). The micro-spherical particles consist of numerous interconnected nanosheets with thickness of about 30 nm. The morphology of Ni/Co LDH-55 presented in Figure 2b resembles that of Ni/Co LDH-40. The nanosheets with thickness around 20 nm are gathered in 3-D arrangements (Fig. 2b inset). When the reaction temperature increases to 70  °C, the microspheres of sample Ni/Co LDH-70 become well defined,defectless and uniform (Fig. 2c). Their size distribution is narrow with maximum at 3 ÃŽÂ ¼m. The detailed features of Ni/Co LDH-70 are shown in the Figure 2c (inset) where high-quality 3D flower-like microspheres are visible. The thickness of the nanosheets is about 15 nm. Wh en the Ni/Co LDH material was prepared at 85  °C, the microspheres are not well-defined and some debris are visible (Fig. 2d). The spherical particles have a loose structure and some collapsed nanosheets overlay each other to construct larger sheets. Enlargement of the flower-like microsphere indicates that the nanosheets are interconnected and well-organized in three dimension (Fig. 2d inset). The thickness of nanosheets increases slightly when the temperature increases from 70  °C to 85  °C.    In order to confirm the defectless microsphere/nanosheet morphology of Ni/Co LDH-70 sample, its internal structure has been further investigated by TEM. Figure 3a shows that the microsphere is assembled from nanosheets and the diameter of the microsphere is around 3 ÃŽÂ ¼m. The internal structure of microsphere is spacious and the nanosheets are the aggregates of even thinner layers. X-ray fluorescence (XRF) spectra were recorded for all samples. On the spectra, three marked peaks at 6.93, 7.48 and 8.26 KeV are identified as Co KÃŽÂ ±, Ni KÃŽÂ ± and Ni KÃŽÂ ², respectively. This supports the co-existence of Ni and Co elements in all samples. Moreover, a peak at about 2.62 KeV is assigned as Cl KÃŽÂ ±, which originates from the interlayer anion Cl. It is interesting that the Ni/Co ratio of the as-obtained samples increased gradually with an increase in the temperature. This may be linked to the differences to the solubility constants of hydroxides (Ksp(Co(OH)2 )>Ksp(Ni(OH)2)) and to the effect of temperature on that solubility [11].    The results obtained suggest that the reaction temperature plays a crucial role in the formation of microspheres. The nucleation of Co(OH)2/Ni(OH)2 took places upon the addition of metal ions to the NH4Cl/NaOH solution. In such a system the involvement of OH in the formation of metal hydroxides competes with the formation of ammonia (NH4Cl+ NaOH à ¢Ã¢â‚¬  Ã¢â‚¬â„¢NH4+ + OH + NaCl à ¢Ã¢â‚¬  Ã¢â‚¬â„¢NH3 + H2O, Co2+ + OH à ¢Ã¢â‚¬  Ã¢â‚¬â„¢Co(OH)2, Ni2++ OH à ¢Ã¢â‚¬  Ã¢â‚¬â„¢Ni(OH)2). This affects the amount of OH reacting with metal ions. The size of nanosheets/hydroxide units increases with an increasing temperature owing to more energy provided to the system. This leads to a gradual increase in the sizes of microspheres built of these nanosheets. Even though the temperature range of the alkaline solution was not very broad and between 40 and 85  °C, 70  °C was found as the only temperature resulting in the uniform and defectless microspheres. Lower temperature of the system has an adverse effect on the formation of microspheres, likely due to the thicker nanosheets than those formed at 70 oC. On the other hand, higher temperature likely leads to collapsing of the formed microspheres [16]. 3.2 Electrochemical tests To evaluate the electrochemical performance of the synthesized materials, the cycling voltammetry (CV) curves were measured for Ni/Co LDH materials at a scan rate of 5 mv s-1 in 6M KOH aqueous solution (Fig. 4a). It is clearly seen that all curves exhibit a pair of redox peaks. An anodic peak is around 0.45 V and a cathodic peak- at about 0.2 V. They represent typical features of Faradaic pseudocapacitance representing the following reactions [6, 17]. Ni(OH)2 + OH à ¢Ã¢â‚¬  Ã¢â‚¬  NiOOH +H2O +e-  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   (1) Co(OH)2 + OH à ¢Ã¢â‚¬  Ã¢â‚¬  CoOOH+H2O+e-  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   (2) CoOOH+OH à ¢Ã¢â‚¬  Ã¢â‚¬  CoO2+H2O+e-  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   (3) The shapes of the CV curves indicate that Ni/Co LDH-70 has the highest specific capacitance [18]. To further investigate the capacitive behavior of our electroactive materials, the galvanostatic charge-discharge (GCD) measurements were performed in a three-electrode system and the specific capacitance (Cs) was calculated from the following equation (4): (4) Where I is a constant discharge current (A), Άt is discharge time (s), ΆV is the potential difference, m is the mass of active material. The GCD measurements in a potential window of 0-0.5 V are recorded at a current density of 1 A g-1 (Fig. 4b). The results show that the discharge time of Ni/Co LDH-70 is much longer than those of other electrodes. Based on the GCD curves, the specific capacitance was calculated. The values are 777, 608, 114,2 and 1017 F g-1 for Ni/Co LDH-40, Ni/Co LDH-55, Ni/Co LDH-70, and Ni/Co LDH-85, respectively. Wang et al. [19] prepared Ni/Co nanoplates using a surfactant assisted method. The rough nanoplates of an increased surface area displayed the specific capacitance of 311 F g-1, which was 2.3 times higher than that of smooth-surfaced Ni/Co nanoplates. It was concluded that creating more interspaces or a larger area can improve an electrochemical performance [19, 20]. Amongst our samples, Ni/Co LDH-70 with three dimensional defectless microspheres exhibits the highest capacitance. This texture promotes the electrolyte access to the more active centers than those available to electrolyte i n more defected microspheres of the samples synthesized at other temperatures. Since Ni/Co LDH-70 exhibits the best performance, its CV curves were measured at the scan rates 5, 10, 20, 50 and 100 mV s-1 (Figure 4c). The shape of the CV curves remains almost unchanged with an increase in the scan rate, suggesting a quick CV response with fast potential sweep and promising capability for energy storage [21]. In addition, all CV curves present a well-defined reduction and oxidation peaks with a slight shift in both cathodic and anodic peak potentials with an increasing scan rate. This suggests that an ion diffusion rate limits the redox reaction [22]. GCD curves of Ni/Co LDH-70 at different current densities (Fig.4d) show two visible voltage plateaus in the charge and discharge parts of the plots. More importantly, the GCD curves of Ni/Co LDH-70 are highly symmetrical at various current densities, indicating fast and good electrochemical reversibility of the Faradaic redox reactions. The capacitance of Ni/Co LDH-70 calculated from the GCD curves at the current densities of 0.5, 1, 2, 3, 5, 8 and 10 A g-1are 1142, 1130, 1098, 1081, 1053, 994, and 970 F g-1, respectively. The capacitance values gradually decrease with increasing current densities from 0.5 to 10 A g-1, owing to the fast electron transfer [23]. Ni/Co LDH-40, Ni/Co LDH-55 and Ni/Co LDH-85 exhibit the capacitance of 777, 608 and 1017 F g-1, respectively. It is important to mention that the specific capacitance of Ni/Co LDH-70 is 970 F g-1 at a high current density of 10 A g-1, and it consists of 84.9% of that at 0.5 A g-1. For Ni/Co LDH-40, Ni/Co LDH-55 and Ni/Co LDH-85 , the corresponding values are at 610, 392 and 812 F g-1 representing the capacitance retentions of 78.5%, 64.5% and 79.8%, respectively. Such differences in the electrochemical performance can be explained by the morphology differences between the samples. As discussed above, the Ni/Co LDH-70 sample consists of uniform three dimensional microspheres built of nanosheets with the interspaces between them. These spaces increase the electrolyte access to the surface of the active materials. Thus the interconnected thin nonosheets in defectless microspheres provide more active sites for reactions with the electrons, which leads to the high capacitance [24, 25]. Electrochemical impedance spectroscopy (EIS) measurement is one of the fundamental methods to examine the electrochemical behavior of electrode materials. The Nyquist plots for the Ni/Co LDH materials in a frequency range of 100 kHz to10 mHz are displayed in Figure 5a. All the impedance spectra of the Ni-Co LDH materials are very similar to each other with a small semicircle at high-frequency and an inclined line at low-frequency [26]. The point intersecting with the real axis (Z) at the high frequency represents the internal resistance, which includes the total resistances of intrinsic resistance of active materials, electrolyte resistance. and the contact resistance at electrolyte/electrode interface (Fig. 5a inset) [27]. This value is almost the same for all electrodes. The semicircle at the high frequency corresponds to the charge transfer resistance (Rct) [28]. At low frequencies, the liner part shows the Warburg impedance resulting from the ion diffusion resistance of the elect rolyte in the active material [21]. Ni/Co LDH-70 exhibits the smallest semicircle diameter, which suggests the minimum charge transfer resistance and maximal electrochemical conductivity. The straight line at low frequencies range is close to Z axis. This suggests that the capacitive performance is not only related to the diffusion process but double layer can also form [21, 29]. The effective ions diffusion and electron transfer of the Ni/Co LDH-70 electrode can be linked to the well-organized three dimensional and defectless micropheres [30]. For the evaluation of the feasibility of practical application of our materials, we constructed the asymmetric supercapacitors with Ni/Co LDH-70 as a positive electrode and activated carbon (AC) as a negative electrode in 6 M KOH solution. The charge-discharge measurements of the Ni/Co LDH-70 were carried out at the current density range from 0.2 to 2 A g-1 with an operating potential from 0 to 1.6 V (Fig. 5b). All curves show the symmetric-like shape, indicating the high electrochemical reversibility of the process. In addition, Ni/Co LDH-70 displays a small voltage drop at the beginning of the discharge process due to the internal resistance [31]. The values of specific capacitance of Ni/Co LDH-70 calculated from the galvanostatic charge -discharge curves are 163.5, 151, 137, 133 and 129 F g-1 at current densities of 0.2, 0.5, 1, 1.5 and 2 A g-1, respectively. And 78.7% of the capacitance is retained when the current density increases from 0.2 to 2 A g-1. For comparison, the specif ic capacitances of all supercapacitors tested are collected in Table 2. The supercapacitors of Ni/Co LDH-40, Ni/Co LDH-55 and Ni/Co LDH-85 show the specific capacitance of only 109, 86 and 150 F g-1 at 0.2 A g-1. They still keep 84, 62 and 117 F g-1 at 2 A g-1, respectively. The capacitances of Ni/Co LDH-40, Ni/Co LDH-55 and Ni/Co LDH-85 maintain at 77.2%, 72.3% and 78.2%, respectively, when the current density increases from 0.2 to 2 A g-1. Based on those specific capacitance values, the energy and power densities of supercapacitors were further calculated ( and )[32]. Figure 5c shows that the energy densities decrease gradually with the increase in the power densities for all cells. At the same power density, the energy density of Ni/Co LDH-70 is much higher than those of other cells, which means that the Ni/Co LDH-70 cell has superior performance in terms of both energy and power density. The energy density of the Ni/Co LDH-70 is 58.13 Wh kg-1 at the power density of 160 W kg-1. Even at a high discharge current of 2 A g-1, the energy density still remains at 45.78 Wh kg-1 at a power density of 1600 W kg-1. Compared to other samples, the asymmetric supercapacitor of Ni/Co LDH-70 exhibits a significant improvement in both power density and energy density. This may be due to its broad potential window of 0-1.6 V and the high specific capacitance. The well-defined three dimensional microspheres of Ni/Co LDH-70 lead to the excellent energy-power combination. The results are comparable with those reported in the literature [5, 6]. For instance, Li et al. reported a new synthetic method for preparation of 16 nm-ultrathin NiCo-based layered double hydroxides (LDH) in an ethylene glycol solution. Their assembled asymmetric capacitor exhibited an energy density of 33.7 Wh kg-1 at power density of 551 W kg-1 with a 1.5 V operating voltage [5]. Tang et al. synthesized nickel cobalt double hydroxide nanoflowers with various Ni/Co ratios using a simple hydrothermal process at 120  °C. Their asymmetric supercapcitor exhibited 19.4 Wh kg-1 at 80.5 W kg-1, and even 20.6 Wh kg-1 at 3.93 kW kg-1 [6]. Cycling stability is a prime factor for evaluating the practical performance of asymmetric supercapacitors. Figure 5d collects the capacity for 2000 cycles of charge-discharge measurements between 0 and 1.6 V at a current density of 1 A g-1 in a two-electrode system. The capacitances of all Ni/Co LDH remains almost unchanged. With an increasing cycle number, the interfacial contact between the active material and a nickel foam may deteriorate, owing to the volume change of the active material during charge-discharge process. This might lead to a higher ohmic resistance of the asymmetric supercapacitors [33]. The calculated capacitances from GCD curve retain about 84.7%, 88.4%, 92.2% and 91.5% of their original capacitances after 2000 cycles for Ni/Co LDH-40, Ni/Co LDH-55, Ni/Co LDH-70 and Ni/Co LDH-85, respectively. The asymmetric supercapacitor of the Ni/Co LDH-70 shows a better cycling stability than those reported for other supercapacitors consisting of Ni/Co hydroxides [5, 6]. 4. Conclusions Ni/Co LDH of diverse morphologies determined by different particle sizes and thicknesses of nanosheets have been successfully prepared at various reaction temperatures in NH4Cl/NaOH mixture. Apparently the temperate affects the amount of OH and the kinetic of its release. Both those factors govern the morphology of assemabled Ni/Co LDH. The synthesized materials showed differences in their electrochemical performance. The Ni/Co LDH-70 (prepared at 70 °C) consists of uniform, defectless and well-defined microspheres with diameters around 3 ÃŽÂ ¼m. These 3-D microspheres are constructed from interconnected ultrathin nanosheets. Such an arrangement provides the space accessible to electrolyte and enables an efficient utilization of active centers. It also results in a high stability of the electrode upon cycling. Ni/Co LDH-70 shows the highest capacitance of 1142 F g-1 at a current density of 0.5 A g-1 and the value is still at 970 F g-1 at a high current density of 10A g-1, which is 84.9% of that at 0.5A g-1. The asymmetrical Ni/Co LDH-70 // activated carbon (AC) supercapacitor was tested in two-electrode system with a wide potential window of 0-1.6V. The results show that highest energy density of the Ni/Co LDH-70 reaching 58.13 Wh kg-1 at the power density of 160 W kg-1. Even at a high discharge current of 2 A g-1, the energy density still remains at 45.78 Wh kg-1 at a power density of 1600 W kg-1.

Prostitution in the Victorian Era Essay -- Exploratory Essays Research

Prostitution in the Victorian Era There were many prostitutes during the Victorian era. Most were lower-class women, with the exception of the mistresses kept by upper-class men. According to Victorian standards, respectable women did not consider sexual intercourse pleasurable. It was their duty to be intimate with their husbands. Having affairs was disgraceful (Waters). Prostitutes, on the other hand, were sexually intimate with men because they enjoyed sex. Men enjoyed prostitutes because they could not enjoy their wives. Victorian femininity was not defined by sexual pleasure, while Victorian masculinity was defined by sexual pleasure and conquest.    Prostitutes did not necessarily â€Å"enjoy† their sexual encounters with men, as Victorians tended to believe. Prostitution was their survival. Lower-class women did not become prostitutes because they wanted to. They became prostitutes because they had no alternate choice for survival. There were few options that allowed women to live off her own income instead of her family’s income, and once she e...

Military Dictatorship and Hieratical Political Leaders Essay

Military dictatorship and hieratical political leaders failed in Bangladesh Military dictatorship and hieratical political leaders failed in Bangladesh to institutionalize democracy and ensure development and liberty for the people. It looks like that we have to restart from the beginning. As early as 1965 the late Akhter hamid Khan of Comilla Academy had a vision to take government to the doorstep of common people through a local government and micro- enterprises under cooperative with management support from a rural based bureaucrats and reduce the revenue urden of the central government a corresponding reduction of members in the centralized bureaucratic administration. To invoke public propositions and opinion in this regard, the following few points have been innumerate to be further developed in future. . Bangladesh was liberated by the toiling masses at great sacrifices primarily by farmers, labors and students, though history did not credit them for their role and instead placed all laurels and benefits of the liberation war to the army, politicians, bureaucrats, greedy elitist and business community to whom all the ealth and privileges and legal concessions of all the Governments have been showered upon. Another liberation war is necessary to liberate real peo ples and ensure their development. 2. points were fundamental basis of ensuring all right, entitlement & Justice to peoples of a promised Sonar Bangla. On that same basis we have to restructure & reform our executive & Judicial functions with maximum autonomy & power to local government leaving only such functions as National security, Foreign affairs, Currency, reserve bank & federal financial affairs, Planning upport and coordination, One integrated national Industrial corporation for development of Basic & large Industries, One integrated R & D council for development of Science and technology, with major emphasis on empirical research. One National Multimode integrated Transport Network System, One National IT Centre for networking all ministerial & local government functions, archiving and retrieving data and information etc. 3. Democracy, Socialism, non-alignment and secularism were the basis of our constitution which was tempered and tailored many times by all Governments to suit certain specific objective of some leaders and their party. The basic principles of a constitution should be sealed for any amendment except through referendum only. The 1st constitution of Bangladesh had some clauses with embedded party interest such as preventive detention under article 33, unrestricted tenure for PM;s office article 57, Local Govt. structure and power as in article 59 & 60, blind following of party line as in article 70 and many others. Though all parties derive certain benefits from these, they must be recast to reflect public pinion on them. . The chapters and clauses on part VI Judiciary contains no structural, Judicial and procedural reforms to ensure dispensing timely Justice within affordable cost. The system has become single biggest obstacle towards â€Å"prevention of vices and chapters and clauses on part IX Services of Bangladesh contains no structural and procedural reforms to convert the servants of the colonial masters to respectable employees of the People’s Republic of Bangladesh. Myopic planning, redtapism and fund crumpling are common causes of all or most project failures in Bangladesh. PSC failure to recruit proper personnel on the basis of personnel integrity, meritocracy, accountability and preference to generalist in place of function based specialist are major causes for rise of a elitist, high living and corrupt bureaucrats who hold every thread of power over political government and who will never allow local government function to be within control of elected local government as the same will hamper their financial interest. . Reorganization of Statutory bodies ; state owned enterprise, public undertakings including banking, securities, and non banking inancial enterprises in Bangladesh is essential as they have substantial bearing on our economy caused due to drainage of capital through loans given to be subsequently classified. Project failure and loss of employment, flight of capital and money laundering, low FDI, management failure, undisciplined labor, lack of accountability and transferency etc. 7. Prepare a total guide line proposal for long, medium and short term development plan for developing Bangladesh with a vision to raise it to a modern state with an egalitarian society by dismantling the existing horrible wealth gap between rich and poor.
