Debates and essays - Research Paper Example This has created problems with the Palestinians who feel that they were dispossessed. Even in the West Bank, nominally a Palestinian state there is Jewish settlement and brutal military repression. This issue, and the resentment of the Arab states about a Jewish state in the Middle East has led to many wars (1956, 1967, 1973, the Israeli invasions of the Lebanon in 1982, 2006 and the 2009 Israeli invasion of the Gaza). Iran has been a country much longer than Israel. In 1978 a revolution deposed the Shah and started an era of theocracy or religious government. Internally and externally the government has adopted very pro-Islam policies including threats to destroy Israel. Iran has also worked to develop a nuclear program nd nuclear missiles capable of targeting Israel. The Iranian nuclear threat is at the heart of the current diplomatic conflict between Israel and Iran. This is somewhat unfair. Israel has nuclear weapons, although it does not officially admit that it does. Therefore, it is difficult, particularly for Muslims, to understand its stance that Iran cannot have them.2 On the other hand, both Israel and the United States are adamantly opposed to Iran developing nuclear weapons. After meeting U.S. Vice-President Biden on November 8, 2010 a source told Aljazeera, ââ¬Å"The only way to ensure that Iran will not go nuclear is to create a credible threat of military action against it if it doesnt cease its race for a nuclear weapon."3 Israel attacked a suspected Iraqui nuclear reactor in 1981 and a suspected Syrian reactor in 2007. It is suspected of planning to attack Iran in the same way.4 The second key issue is Israeli settlement in the occupied West Bank. Iran strongly opposes this, as do the United States and the United Nations. However, Israel recently ended a 10-month freeze on settlement and has settled 500,000 persons in the illegally occupied West Bank since 1967.5 The

aztecs: Incas :: essays research papers
Aztecs: Incas à à à à à At the time the Spaniards arrived to the New World they found different Indian civilizations with many similitude and differences. In Mexico the Spaniards found a very stable empire called the Aztecs; the Aztec empire controlled a region stretching from the Valley of Mexico in central Mexico east to the Gulf of Mexico and south to Guatemala. The Aztec built great cities and developed a complex social, political, and religious structure. Spaniards found another Indian civilization called Incas Empire; it was a vast kingdom in the Andes Mountains of South America, but at the time of the Spaniards conquest the empire was in a huge crisis caused by the death of their leader. Before the crisis, the Inca government system was among the most complex political organizations of many Native American cultures. Although the Incas lacked both a written language and the concept of the wheel, they built large stone structures without mortar and constructed suspension bridges and roads that crossed the steep mountain valleys of the Andes. These two empires were passing for different situations at the moment of the contact; finally the Spaniards obtained the control and star controlling the empires. à à à à à The Aztec Empire was a Native American state that ruled much of what is now Mexico from about 1428 until 1521, when the empire which was very stable; The Aztecs empire was conquered by the Spaniards. The Aztecs empire represented the highest point in the development of the rich Aztec civilization that had begun more than a century earlier. The Aztec built great cities and developed a complex social, political, and religious structure. Their capital, Tenochtitlà ¡n, was located on the site of present-day Mexico City. Tenochtitlà ¡n was an elaborate metropolis built on islands and reclaimed marsh land, Tenochtitlà ¡n was possibly the largest city in the world at the time of the Spanish conquest. Tenochtitlà ¡n featured a huge temple complex, a royal palace, and numerous canals. Aztec cities were also dominated by giant stone pyramids topped by temples where human sacrifices were dedicated to their Gods. à à à à à Aztec society was highly structured, based on agriculture, and guided by a religion that pervaded every aspect of life. The Aztec worshiped Gods represented natural forces that were vital to their agricultural economy. Although Aztec society had strict classes, a personââ¬â¢s status could change based on his or her contribution to society. The society was divided into different classes like for example the leader, the nobility, local rulers, military, priestly, artisans, and commoners (Class notes from 5/12/05).

Symbols and Symbolism in The Wraith of the Rose :: Wraith of the Rose Essays
Symbolism in The Wraith of the Rose "The Wraith of the Rose" is poem that seems to suggest the dual nature of love and relationships. There is the love and joy that is represented by the natural beauty of the flower, which is accompanied by the bitterness of a love that was lost and the pain that remains. The idea that love sours is not new, but in this poem there is the wraith, which is a ghost, that represents the pain that love can bring. One of the most interesting sections of the poem that goes from line 13 to 23 and starts with "I wish" in groupings of three reflects the desires of a lover looking back on a past relationship and the longing to go back to the happier days of the relationship. This longing is just as evident in the rest of the poem and is solidified with the symbolism of the wraith. The first groupings of "I wish" start with a genuine sentiment by the author to again be in the place where "the chain was still unbroken" and to have " kept that last fond token". This entire group suggests that the author keeps fond memories of the relationship. In the next groupings of "I wish" the author starts to point the finger at the other person in the relationship by using the line "I wish you were not all deceit". This is the first instance where the author expresses anger about the break-up the relationship and does not recall memories with fondness. Although the author does address her own faults by saying, "And I so fickle-hearted", she stills holds contempt for her past lover. I am somewhat surprised that it took this long for the author to place blame on the other person because of the fact that most people and selfish and assume that the reason for a relationship not working is always the fault of the other person, not their own. The third groupings of "I wish" further implicates the other person as the cause for the failure of the relationship and the reason why they are not together now. She writes "I wish you could reclasp the chain" and "I wish- you hadn't drunk champagne". These lines have an honesty about them and ring true to the feelings of a normal person dealing with the loss of a relationship.

Out of School Youths Essay
Out of school youth means having a vulnerable people who have needs. Nobody can deny the hard fact that education is an extremely important factor for bringing change in the lives of individuals. It has universally been recognized as the most powerful instrument and pre-requisite for gearing up the socio-economic development of a nation. In fact, it can be said that it is a pre-condition for the overall up-lift and welfare of a nation. This is why investment in education is considered to be so vital for human resource development and the enhancement of the quality of manpower. The history of humankind, in general, and that of developed nations of the worked, in particular, is replete with the precedents, which establish the fact that a certain level of literacy in population is an essential pre-requisite for precipitating the process of development in a country. The segment of society that plays the most active part in the socio-economic development of any country/region consists of the adolescents. It is clear that the composition and characteristics of this most crucial part of population goes a long way in expediting the process of national development and influencing the policy makers and planners in their planning and decision making for the future. In this way, the adolescents act as a sort of a ââ¬Å"pressure groupâ⬠that exerts a far-reaching impact on the process of educational planning as well as on the other developmental activities of the country.

Free Essays on The 21st Century Economy
The 21st Century Economy in the United States can be characterized as a very prosperous economy. The article ââ¬Å"The 21st Century Economy.â⬠In Business Week describes how the 90ââ¬â¢s are no fluke. This decade has turned out to be a decade of unexpected prosperity. When the United States came out of World War II, United States productivity growth was at high levels. Then in the 1970ââ¬â¢s it dropped mysteriously. This low productivity growth continued to the middle of the 1990ââ¬â¢s and was thought to continue this way. Suddenly in 1995 productivity gains started to rise to overwhelming heights. In long run economics, productivity growth is the most important. This determines the path of income per capita, which effects out living standards. According to Robert D. McTeer, president and chief executive officer of the Federal Reserve bank of Dallas, two factors determine the rate of economic growth; productivity increases (more output for the same amount of inputs), and labor (the number of hours worked. There are many benefits that go along with the economic expansion we are experiencing. The current expansion has commonly been referred to by economists as ââ¬Å"The 1990ââ¬â¢s Economic Boomââ¬â¢, because the current growth of the United States economy is the longest ever in peacetime.

FINLAND ENERGY POLICY Term Paper Example | Topics and Well Written Essays - 1500 words
FINLAND ENERGY POLICY - Term Paper Example The ministry has been capable of establishing and exceptional versatile and decentralized energy system; they are based on both small and large energy production plants and a variety of energy sources. Finland itself has been capable of developing a strong energy technology or the energy cluster and it has grown in importance. The country has been in the forefront in the decreasing unnecessary regulation and therefore it has created preconditions for the greater efficacy and internationalization among the Finlandââ¬â¢s energy companies (Ministry of Employment and the Economy, 2011). The Finland energy policy is based on three fundamentals: environment, economy and energy. The core elements of the policy are to secure the energy supply, develop competitive prices, and to meet the European Union common Energy and Climate goals. Another important principle is the integration of the environmental goals, other types of sustainable developments with the economy of energy. It is imperative to note that at each stage of the programme, the prospective price, the availability of the imported energy, and the larger frequency in which the decisions are made at the international level affect the energy policy (Ministry of Employment and the Economy, 2011). The energy policy of Finland is implemented in regard to the drawn-up energy policy documents like the objectives that have been set in the governmental negotiations and the Governmentââ¬â¢s Energy Policy Programme. There are factors that underpin the realization of the Finland energy policy and they are special programmes such as the National Climate and Energy Strategy and the international commitments. The energy policy was adopted in 2008 and it is determined by the National Climate and Energy Strategy and its additional programmes. The drafting of the Climate and Energy Strategy was done in consideration of the principles that underlie the energy

CRITIQUE OF EARLY CHRISTIAN TEXT-- --POLYCARP'S LETTER TO THE Essay
CRITIQUE OF EARLY CHRISTIAN TEXT-- --POLYCARP'S LETTER TO THE PHILIPPIANS - Essay Example The date of the Letter is hardly satisfactorily determined; often scientists take as the reference point martyrdom of Polycarp (Palmer 3). The texts written in this period (late 1st and early 2nd centuries) have been influenced in more or less grade Jewish motifs that ââ¬Å"pervaded Christian thinking and practice at this primitive stageâ⬠(Patristic literature). The Holy Spirit even in extremely bias translations saves all the major doctrines. In every way it leads the person to Jesus. There are several translations of the Epistle of Polycarp and each of them has something to convey and bring (Church History 39). The doubts against the authenticity of it, especially the last chapters, surviving only in the ancient Latin text, cannot be considered thoroughly, because critics did not want to accept the message of Polycarp in its full form as it contained the words about the letters of Ignatius Antioch. The Epistle to the Philippians was written shortly after the death of St. Ignatius. It was caused by a petition to the Christians of the city Philip of habeas letters of Ignatius to Polycarp and other Christians, what he had, to them. Fulfilling their request, the Bishop of Smyrna gives them a number of Christian teachings, warns against the heretics, tells the responsibilities of presbyters and deacons, men and virgins, spouses and widows, he convinces to avoid covetousness, to practice praying and fasting, and instills patience and love for enemies. For a long time the Greek text of the Polycarp`s Letter contained first only 9 chapters and the remaining 5 chapters were preserved in the ancient Latin translation. So from the point of view of contemporary scholars they could be placed to a category of Jewish-Christian literature. Polycarp`s letter is a sign of growing awareness of the traditions of Christianity. His letter is also supplemented with verses from the New Testament: ââ¬Å"The strong root
Life in the Colonial Convent. in Latin America Research Paper
Life in the Colonial Convent. in Latin America - Research Paper Example Conquering nations placed value on convents. Monastic life gained respect and power in the society. Distinction of ethnicity, honour, and gender between the nuns increased with the passage of time. Many individuals were being used as slaves and servants in the convents. Convents generated financial resources by getting money from wealthy families; this defined numerous classes of people as per their financial standings (Bethell 56). Factors like demography, spatial variations and economy caused differences in womenââ¬â¢s lives. Spanish women were given almost all the rights and protection during the colonial period in Latin America. Education and protection for women was ensured at the convents but other races and classes suffered as there were no rights and convent for them in Latin America (Skidmore & Smith 71). Latin America was male dominated colonial world and women were not allowed to take part in any activity without the permission of male. Male member of the family was onl y allowed to take all decision in day-to-day social life. Race and class distinction was firmly enforced and people were dealt accordingly. Women used two types of veils for differentiating leaders from servants. Nuns wearing black veils were from wealthy families and brought all the precious items with them. ... Mestizo women were only employed as servants. These practises at the convents enacted social barriers in the human life in the colonies (Edwards 128). Convents were initially established only in the main cities of Latin America. Walls were built to separate the convents from the cities. That is why convent used to give a deserted look. Keeping of slaves and servants in convents was as normal as in rest of the world. there are numerous examples in Latin America and people also say that between two convents in Cuzco , more than 500 living out of which 50% were nuns (Bethell 61). Influential families lived in separate homes within the convent and kept orphan girls as servants along with other servants. Dona Juana de Maldonado constructed good house for herself. She used dozen of black maids in construction of accommodation in the convent. Juana also spoke about gender double standards in her poems (Skidmore & Smith 75). Convents in Latin America used multiple sources to generate revenue s. Nuns took oath of obedience and poverty to their superiors. Wealthy families residing in convents could not manage to give a luxurious life to their daughters because a huge amount of money was paid to church and convent. Nuns were considered ââ¬Å"brides of Christâ⬠so all nuns were expected to give their dowry to church. Quantity of dowry presented to church, dictated the amount of luxurious lives that nuns can live. 6000 pesos was entry fee in the convent in Lima. For a luxurious living, convent used to charge double amount (Edwards 132). Demography, spatial variations and economy caused differences in womenââ¬â¢s lives in colonial Latin America. Islamic way of social life was fully followed by the Iberian women during the colonial age in old and the new world.

Alcoholics Anonymous Assignment Example | Topics and Well Written Essays - 1250 words
Alcoholics Anonymous - Assignment Example Focus is given to the purpose, leadership, membership, decision making process and the general functioning of the group. The main reason for formation of Alcoholics Anonymous group was to rescue members from abuse of alcohol and similar substances (Mckellar, Stewart & Humphreys, 2003). Although the group was started in Ohio in 1935, it has grown to all other US states and beyond (Mckellar et al., 2003). As the name suggests, one of the principles of AA is that its membership should always remain a secret (Mckellar et al., 2003). Apparently, the main purpose of this principle is to shield members from public ridicule that can easily compromise rehabilitation process. The AA has been very effective in helping people abandon alcoholism (Moos & Moos, 2006). According to Moos and Moos (2006), the group does not use scientific therapies but rather members come together to help each other deal with the problem of alcohol and drug abuse. In this regard, new entrants are linked to already rec overed members for assistance. As noted by Moos and Moos (2006), in addition to helping members to quit unhealthy drinking habits, AA also creates conducive environment to enable them cope with their new life. Some psychologists have suggested that AA can become more effective if scientific medication is incorporated in the groupââ¬â¢s traditional methods of fighting alcoholism (Moos & Moos, 2006). The functioning of AA group is based on a program of twelve steps that start with entry of addicts and end with exit of fully recovered individuals who are ready to assist other alcoholics (Sharma & Branscum, 2010). According to Sharma & Branscum (2010), there are twelve traditions used as the constitution of the group. The traditions guide members on how to relate with each another. Some of the most embraced values include group unity, fear of God and self-support (Sharma & Branscum, 2010). Since the group is open to any person willing to fight addiction, there is no minimum or maximu m membership requirement (Sharma & Branscum, 2010). The meeting attended by the author was held on Saturday evening in a four walled room. The timing of the meeting was designed to avoid inconveniencing members as most people are free during Saturday evenings (Harrison, Price, Gavin & Florey, 2002). In addition, Harrison et al. noted that meeting at the time when most people are free ensures that members are occupied and wonââ¬â¢t find time to engage in unhealthy drinking (2002). The seating arrangement was similar to a learning classroom where learners sit in rows facing one side. Unlike most meetings where group officials sit in front, there appeared to be no distinction between leaders and other members in the AA meeting. This arrangement was designed to discourage any feeling of authority by perceived leaders. It is believed that a sense of equality among members encourages free flow of information within the group. In this regard, the group did not have official leaders. Whe never there is a meeting, any member can volunteer to lead the group through the process (Moos & Moos, 2006). As Moos and Moos notes, the volunteer is only a coordinator rather than a leader (2006). Decisions are made through deliberations of the entire group. However, decisions that only affect certain individuals are made by such individuals but other

Preliminary Stage - Research Paper Example This had even led many Americans to go through financial bedlam and disarray2. Meanwhile, in Chicago, while the stock market headed off a declining path, the Worldââ¬â¢s Columbian Exposition emerged wherein it highlighted the advancing technology and culture of the city. Amidst the economic turmoil experienced, Americans gaped at the new innovations brought about by the economic transition of the United States. Celebration for the accomplishments of the corporate America was emphasized. Nevertheless, it was in this phase of the United States economic history that a new style of music emerged that would enable Americans to identify themselves in an evolving modern nation. The economic crisis of 1893 and the Worldââ¬â¢s Columbian Exposition, and their enigmatic description had a monumental effect on the American culture: a time when America adopted ragtime music3; thus, the birth of Jazz. The Early Years of Jazz Ragtime music rose to rapid fame from 1897 to 1917, and this trigger ed modern technological modifications with businesses eyed close relation to Jazz as a national music4. The peaking popularity of the ragtime music likewise stimulated the economy with many piano manufactures increasing their production to accommodate the fast growing need for the instrument. During the 20th century, particularly in the second decade, piano production was at its summit producing more than 400,000 pianos annually. Vaudeville and Minstrel shows also proliferated following the growing number of amateur musicians who started to adopt and learn the art of Jazz music. These shows became prevalent in the United States and offered complete entertainment for many Americans. The Minstrel shows were usually held in salons ââ¬â a relatively smaller venue as compared to theatres. Vaudevilles were staged in theatres, a development that attracted women and children to watch Jazz musical presentations. This had led to the growing audiences of Vaudeville shows that featured Jazz music. Then, Jazz music spread across the United States, particularly in three of its largest cities: New York, Los Angeles, and Chicago. This turned out to be the focal point of the changing American Culture in the 1920s. During the height of ragtime music in which African Americans were leading, the issue on racial discrimination still contaminated the new music industry. Nevertheless, offensive description and racism of African Americans were reduced in order to attract more audience5. The ever increasing fascination to ragtime music paved the way to the dispersal and proliferation of the music through phonographs and radios. This allowed a larger proportion of the American population to get acquainted and spellbound by Jazz. Due to the growing demand, more and more musicians were hired to create and perform ragtime music. And despite the toning down of crude representation of African American musicians, stereotypes against them still survived. Nevertheless, Vaudeville offered t he Black actors and musicians the chance for employment6. The Greats of Jazz and the New Niger There is no question about the popularity of Jazz during the early 20ââ¬â¢s with African Americans acted as pioneers of the musical genre. It was during this period when the Harlem Club was established, debuting the giants of Jazz music: Duke Ellington and Louis Armstrong. But apart from the two pioneers, when it comes to

Some psychologists have suggested that AA can become more effective if scientific medication is incorporated in the groupââ¬â¢s traditional methods of fighting alcoholism (Moos & Moos, 2006). The functioning of AA group is based on a program of twelve steps that start with entry of addicts and end with exit of fully recovered individuals who are ready to assist other alcoholics (Sharma & Branscum, 2010). According to Sharma & Branscum (2010), there are twelve traditions used as the constitution of the group. The traditions guide members on how to relate with each another. Some of the most embraced values include group unity, fear of God and self-support (Sharma & Branscum, 2010). Since the group is open to any person willing to fight addiction, there is no minimum or maximu m membership requirement (Sharma & Branscum, 2010). The meeting attended by the author was held on Saturday evening in a four walled room. The timing of the meeting was designed to avoid inconveniencing members as most people are free during Saturday evenings (Harrison, Price, Gavin & Florey, 2002). In addition, Harrison et al. noted that meeting at the time when most people are free ensures that members are occupied and wonââ¬â¢t find time to engage in unhealthy drinking (2002). The seating arrangement was similar to a learning classroom where learners sit in rows facing one side. Unlike most meetings where group officials sit in front, there appeared to be no distinction between leaders and other members in the AA meeting. This arrangement was designed to discourage any feeling of authority by perceived leaders. It is believed that a sense of equality among members encourages free flow of information within the group. In this regard, the group did not have official leaders. Whe never there is a meeting, any member can volunteer to lead the group through the process (Moos & Moos, 2006). As Moos and Moos notes, the volunteer is only a coordinator rather than a leader (2006). Decisions are made through deliberations of the entire group. However, decisions that only affect certain individuals are made by such individuals but other

Employment Law Protects all Employees from Being Discriminated by Assignment
Employment Law Protects all Employees from Being Discriminated by Their Employers - Assignment Example The male employees who joined ABC after Ms. Riyadh have received promotions. However, Ms. Riyadh is still working in the same position despite her smart work. In this case, Ms. Riyadh can claim the practice of gender discrimination by her employer. Despite her good work to the extent of receiving three national awards, she has not been promoted. Her male counterparts have received three to four promotions within the time Ms. Riyadh has worked for ABC. It is also evident that few women hold higher positions compared to their male counterparts (Duddington, 2007). Ms. Riyadh can also claim the presence of religious discrimination in her workplace. Her employer says that Ms. Riyadh is too religious to hold a higher position within the company. Ms. Riyadh knows that in the employment act, an employer is not supposed to discriminate against any employee based on the employeeââ¬â¢s religion. All employees should get equal chances for promotions. In this case, Ms. Riyadh will claim that h er employer has not been fair in considering her for promotion based on her strong religious beliefs (Herch, 2007). ABC can defend itself that it will endure business hardship in the process of considering to accommodate Ms. Riyadhââ¬â¢s complains. On the other hand, ABC might defend itself that there was no legally enforceable agreement that Ms. Riyadhââ¬â¢s promotion was an obligation to the company. The promise during the hiring time served to motivate Ms. Riyadh into working hard. Otherwise, there was no contract between the employer, which in this case is ABC, and Ms. Riyadh, the employee. Therefore, ABC is under no obligation of promoting Ms. Riyadh. Both the defenses will allow ABC to win the case and no benefits will be paid to the complainant (Herch, 2007, P.56). QUESTION B (1) In employment law, there is the act protecting special groups from workplace discrimination.
Cultural Diversity Essay Example for Free
Cultural Diversity Essay Cultural diversity is a big part of the community I was raised in and apart of today. Many people spend their whole lives surrounded by one race or culture, but I grew up surrounded by many. Having been raised in a society influenced and shared by so many different races, I had very little idea about what or why racism existed in the world. Having never been taught and seeing very little racism growing up I believed benefited me, today and benefited my future. Today being in the Marine Corps I am surrounded by different races and knowing one day my life could rest in their hands I respect them for who they are not what color they are. Martin Luther King once said ââ¬Å"Men hate each other because they fear each other, and they fear each other because they dont know each other, and they dont know each other because they are often separated from each other.â⬠If the rest of the country had been raised in a military lifestyle then I believe racism would be all but extinct in the United States. Sadly racism is not only intertwined with the United States past but also with its present and its future. Racism has been part of the history of the United States, and helped create this country as we know it today. Racism not helped shaped the United States and infiltrated every aspect of American society while showing no signs of decreasing. Many people view racism as an evil minded treatment of one individual to another. This is not a correct assessment though, and would be more easily understood if it was viewed more accurately, an institutional ideology. The reason racism is allowed to subsist because governments and institutions foster and maintain racism. Even when these governments and institutions determine that the practices of a particular group of people are racist, individuals at the top of these hierarchical organizations are hard pressed to bring about change. To understand how racism relates to us in the United States today, one must understand the real definition of racism. ââ¬Å"Racism is the belief that one group of people with a particular biological make up is superior to other groups with a differing biological make up.â⬠So one could infer that the groups deemed superior gain economic and social dominance over the other cultural groups that are deemed inferior, even with the many strides that have been made over decades to mend the situation. An excellent example of a country that has made those strides and still lack racial reconciliation is the United States. From the bus boycotts in the fifties, to the sit-ins and marches in the sixties one could assume that these would be the starting steps to improvement. While the United States was mending the hatred and racism between black and whites another type of racism was creeping its way into American society. Today racism has taken a new face, one that has become multi-coloured and multicultural. To be able for the United States to keep a culturally diverse appeal new legislation and laws are being written against discrimination. Affirmative action has been taken to allow equal opportunity for employment, housing, and even in the military. Television and movies have had to change their format and even some of their characters in order to obtain political correctness. Even with so many fighting for change, there will always be the ancient invisible barriers blocking the few who are looking to main the status quo. Even with so many people trying to seek improvement for this country, it cannot happen unless every individual is working to abolish racism. There is racism in every facet of life no matter who someone hangs out with, or who someone even works for. Being in the Marine Corps I see different races every day, and work with different races every day. Mission accomplishment is the number one goal of the Marine Corps, so when a job needs to get done every one does their part of their job and race is not an issue. That is the way my career has gone so far, so when I read an article about racism in the Marine Corps it shocks me. New websites and social networking sites are being created all the time. A new social network website was created with the logo ââ¬Å"online community for whites by whitesâ⬠, so it was a social website for only white people. Out of the many number of people who have made a profile there have been about forty personal profile that have listed the military as their occupation. Out of those forty a number of them are wearing their military uniforms in their profile pictures. Even more disturbing a number of the military members have poster racial slurs and racial propaganda. One member states that he hate(s) illegal immigrants with a passion and feel(s) every true red-blooded, white American should do whatever it takes to stop the foreign invasion. While another lists The Turner Diaries, which is a white supremacist novel, as his favourite book. It is important for members of the armed forces to not participate in these types of websites or groups. The first reason not to participate in these organizations is the Pentagon has regulations in affect that prohibit active duty members form participating in extremist groups. The second reason is those racial extremists who serve in the military could be inadvertently training future domestic terrorists, and the United States does not need any more terrorist on her soil. A solution for this problem would be senior military members mentoring their junior service members on the dangers of becoming involved in these organizations. Being in the United States Marine Corp I have many close friends that are from different countries in the world. One of my close friends is from the Philippines, and has a very strong accent when he speaks. Sometimes he gets his words confused and does not make any since when he speaks. Marines tend to point out these faults, not just with him, but with many other Marines that are from different countries and have trouble speaking English. My friend does not believe that his fellow Marines are being racist, but are just having a friendly poke at him. Marines do not mess with only a few Marines, or the Marines from other countries, but every Marine. It is not because we are racist, or are a mean group of people, but picking and jibing on one another is just the way that Marines bond with each other. When my friend says that he is getting picked on, yes it sometimes hurts, but in the end it makes him feel like he is part of the family. If Marines are not being picked on they are usually secluded and out of the Marine Corps family. Racism is wrong and should not be used for any reason, even to bring people together. Racism may start with a good reason, but the final product will fester into an infection that could spread and destroy a family within a short time. Racism is in this world to stay whether people like it or not. Individuals believe that if they spread the word about the dangers and negatives of racism then it will cease to exist, but that is not the truth and will never happen. As long as we humans exist and have emotions, the knowledge of right and wrong, and pride there will be crimes. Whenever a person graduateââ¬â¢s high school as valedictorian or an athlete becomes the fastest man on the planet, stereotypes will follow. Crimes, education, athleticism all turn into a stereotype and stereotypes are a form of racism. Racism is one of the things that drive our great country, and create some of our countries greatest works. Racism is what helped form and mold this country into what it is today. Without racism then this country could be one of a single culture, there would be no freedom to branch out and try new diverse things. The dangers of bringing so many different cultures into one space are there, but I believe the good thing we bring to the table References Vardell, M. (1998). Cultural diversity.

Multifunctional Porous Organics Synthesis
Multifunctional Porous Organics Synthesis TITLE OF WORK The synthesis and characterisation of functionalized porous organics Abstract Lophine based radicals have been studied for many years due to their photochromic nature, recent literature has seen attempts to connect two radicals to carbon based backbones. In this report we will discuss attaching six lophine molecules to a single backbone which is a phosphazene ring. Cyclophosphazene rings have a unique conformation allowing for supramolecular architectures to be formed by varying the substituents, these architectures range from 0-2D structures. The hexalophine molecule exhibits 1D channels due its unique conformation which leads to the formation of a porous material. Porous organics are of high interest in recent literature due to them being a cheaper, less toxic alternative to MOFs as well as having the ability to be modified and tailored easily due to the simple starting materials. In this report we shall state synthetic pathways from simple molecular building blocks to hexalophine (32%) and two derivatives, compound 4 (46%) and 5 (15%). These two derivatives have the potential to increase pore stability. This report will also include the oxidation of hexalophine to its radical species which were found to display photochromic properties and it is also believed that this material could contain light gated pores which are closed in the dimer form of the product but then open upon irradiation of UV of 365nm. 1. INTRODUCTION 1.0 Properties and potential uses of Lophine This report will feature chemistry based upon the triphenylimidazolyl based radicals (TPIRs) as well as the dimer form hexaarylbiimidazole (HABI). Lophine (2,4,5-triphenyl-1H-imidazole) is a heterocyclic imidazole derivative where three phenyl rings are attached to the imidazole ring (figure 1), these imidazole derivatives are an area of importance due to the many interesting properties it possesses. Lophine has been of interest to researchers for many years with its chemiluminescent properties being first discovered in 1877 by Radziszewski.1 The oxidation of the lophine molecule follows the reaction scheme below, where lophine is oxidised to the TPIR radical state via addion of base and treatment with Fe forming one of six dimers both in solution and the solid state (figure 2). These materials display photochromic, thermochromic and piezochromic properties. The mechanism of photochromism of the lophine dimer is the homolytic cleavage of the 2C-1N bond of the dimer by irradiation wit h light, forming two lophine radicals.2 The fast colour change associated with this dimer opening means there is a potential use in display screens or as the basis for molecular switches, where irradiation with light opens the dimer forming the radical in turn switching the external component On/Off. These possible applications have caused a focus on creating methods to manipulate and control the colour of these materials and as well as to increase the rate of switching.3 The colour of the radical form is dependent upon the substituents on the ring, the more conjugated the system the further toward the red side of the spectrum the colour.4 Lophine displays piezochromic properties in its solid state, upon applying pressure lophine crystals the colour change of yellow to blue/green has been observed, this occurs via the radical dissociation of the 1N-1N dimer bond.5 Other more unusual modes have been of dimerization such as the 2C-2C have now also been isolated, this mode features a u nusually long C-C bond.3 Figure 1 The structure of Lophine (2,4,5-triphenyl-1H-imidazole) Another interesting lophyl radical derivative is the 1,8-TPID-naphthalene radical which consists of 2 lophine radicals connected by a naphthalene ring. 1,8-TPID-naphthalene has been characterised in the solid state by Abe et al; who studied the photoreactivity of the compound. 1,8-TPID-naphthalene allowed the group to fix two radicals onto a backbone meaning that the radicals were in close proximity and could dimerise easily as opposed to two radicals not connected via a backbone which first need to find eachother in order for dimerization to occur (figure 3). They found that the dimer could be cleaved photochemically giving the diradical and then could be thermally converted back to the dimer.6 They also found that the formation of a peroxide bridge was much more common than previous literature had accounted for. This bridging occurred when the 1,8-TPID-naphthalene radical was placed under an O2 atmosphere.7 This peroxide bridge formation is very important as when oxygen quenches th e spin to form the closed shell peroxide it does so irreversibly meaning the material is no longer photochromic. It was then shown that this peroxide degradation pathway can be generalised for the chromic dimers of TPIR materials, with non-tethered TPIRs forming similar peroxide bridges.8 A recent development by the same research group has also shown how a thiophene substituted phenoxyl-imidazole radical complex (PIC) can generate two non-equivalent radical upon irradiation with UV light. The colour change can be fine-tuned from tens of seconds to nanoseconds, however a sensitivity to lower wavelengths of light meant that applications were limited. This problem was rectified by adding a phenyl group to the 5 position of the thiophene ring.9 Figure 2 The six potential dimerization modes of two lophyl radicals.3 Figure 3 Illustrates the reversible conversion of 1,8-TPID-naphthalene between its radical and dimer forms. 1.1 Hexa-substituted Phophazene Rings, Tectons and Crystal Engineering A key component of this project was the exploitation of the Phosphazene ring as soft tecton; a tecton is a molecular building block that interacts with sticky sites, formally known as supramolecular synthons, via spatial arrangements to induce the formation of supramolecular aggregates. The search for new tectons is a hot area of research due to the constantly growing field of crystal engineering where the aim is to produce functional single crystal materials using intermolecular interactions. The arrangement of molecules in solid state structures is largely dependent on striking a fine balance between intramolecular forces and packing interactions, knowledge of these forces is key to the field of crystal engineering.10 In general, hard tectons interact via more robust synthons than soft tectons and therefore usually crystallise with unambiguous geometries. Whereas soft tectons and less robust synthons allow for the formation of supramolecular isomers (figure 4).11 These tectons allo w for many functional materials to be formed in a one pot synthesis, they also have the ability to be carefully adjusted to alter and improve upon their functionality.12 Cyclophosphazenes are extremely soft tectons that interact with soft synthons to give a large variety of supramolecular architectures in the solid state. The conformation of the cyclophosphazenes is also very interesting as three substituents reside above the plane of the ring and three below (figure 5). It was found that small modifications to the substituents attached to the ring gave supramolecular architectures ranging from 0D to 2D structures (figure 6) such as include monomer, dimer, cyclic hexamer, zigzag chain, linear chain, double chain, graphite-type sheet, rectangular grid and hexagonal close-packed sheet. Such variety of structures came from the easy rotation about the exocyclic P-N bonds, which allowed variable directionalities for all of the N-H bonds. 11 à à à à à à à à à à à à à à à à à à à à à à à à à 3a)à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à 3b) Figure 4a) Shows benzene-1,4-dicarboxylic acid a classic example of a hard tecton. 4b) shows a silanetriol a classic soft tecton. Figure 5 Conformation of a Hexa-substituted Phosphazene Ring. Figure 6 Schematic representations of aggregation patterns of (RNH)6P3N3 in the solid state.11 1.2 Magnetism and Magnetic Frustration The materials we aim to make during this project once appropriately oxidised should go on to form dimers which when irradiated with UV light form discrete radicals containing unpaired electrons thus giving each radical an associated magnetic moment. Neutral organic radicals tend to be paramagnetic and exhibit Curie- Weiss behaviour, where the spin vectors of the unpaired electrons are randomly aligned above the Curie temperature (Tc), which is the critical temperature below which the long ordered state is established, unless a magnetic field is applied. If spin vectors are parallel to each other below the Curie temperature then the material is ferromagnetic, if the spin vectors are aligned antiparallel to one another the material is antiferromagnetic.13 Due to the geometry of the phosphazene ring (three substituents pointing up above the plane of the ring and three below) there is the possibility of forming a 2D triangular lattice of spins if the substituents are organic radicals.à This could possibly lead to geometric magnetic frustration due to the fact that the two nearest neighbours to a spin are themselves nearest neighbours and therefore antiferromagnetic couplings cannot be satisfied (figure 7).14 This can lead to very interesting magnetic properties. Most solid state examples of this geometric frustration tend to be transition metal oxides, however, studies have been done on organic systems that also distribute geometric frustration.13 One example of this is m-MPYNNP+ which is a spin à ½ organic radical that upon dimerization forms a 2D triangular lattice which demonstrates the aforementioned geometric frustration.14 The issue of spin frustration has been around for a long time as Quantum spin liquids (QSL) were first theoretically proposed by Anderson many years ago which are now a hot topic of research due to the realisation of these QSLs in organic materials such as k-(ET)2-CH2(CN)3, which has a near perfect triangular lattice with angles very close to 120à °.15 A QSL is an exotic ground state where interacting spins continuously fluctuate with no formation ofà low range magnetic order even at sufficiently low temperatures.16 Figure 7 Antiferromagnetic coupling cannot be fulfilled causing geometric magnetic frustration. 1.3 Porous Materials Porous materials are as important as ever due to their wide spread use in several fields such as catalysis and gas absorption,17 meaning they can play a critical role in the route to solving our growing energy shortage problems. Porous materials are instantly associated with materials such as zeolites, metal organic framework (MOF) and organic polymers. MOFs are characterised by their tuneable pores and inherent flexibility which more classical carbon or oxide based structures do not possess, this gives a wide range of applications for MOFs such as gas storage, separation, drug delivery or catalysis.18 Porous organics have been discovered in nature but are largely created synthetically and approaches often need to be coupled with knowledge of crystal engineering. These materials are often held together by directional forces which form extended frameworks of noncovalent interactions such as Ãâ¬- Ã⬠interactions, hydrogen bonding or coordinate bonding (figure 8).17 Like zeolites a nd MOFs porous organics have the ability to selectively absorb atoms and molecules in the gas phase.19 There are many positives to these porous organics, they are often cheaper to synthesise and less toxic as well as being far less dense than metal containing MOFs. Figure 8 One example of a Porous Organic by Sozzani et al. 1.4 P3N3 Hexalophine The chemistry of P3N3 Hexalophine incorporates much of the chemistry discussed above and has many interesting properties. The P3N3 Hexalophine molecule consists of six lophine substituents attached to the phosphazene ring via a P-O bond (figure 9). Previous work in the Robertson group found that the solid state structure of Hexalophine consisted of a pseudo hexagonal motif giving rise to 1D channels that run parallel to the stacking axis (figure 10). The molecule maintained its D3 symmetry in the solid state. The phenyl rings twist to maximise pi-stacking interaction and the 3 imidazole nitrogen atoms form hydrogen bonds to a central water molecule. There are 4 pi-pi interactions that stabilise this structure, the molecules are in a slipped conformation allowing the phenyl and imidazole to rings overlap. Other non-covalent interactions such as van der Waals interactions also help to stabilise the structure. The high symmetry of the structure which comes from the hexa substituted phos phazene ring (three above the plane of the ring and three below) gives an equal distribution of intermolecular forces giving a high probability of forming a stable porous structure. IGA measurements with CO2 loading at 195K shows a Type I isotherm with absorption reaching 8cm3g-1 at a pressure of 700mmHg confirming the materials microporosity. However only a small fraction of the void space contained CO2. Figure 9 The structure of Hexalophine. Figure 10 The crystal structure of Hexalophine, illustrating the 1D channels. 1.5 Aim of Project The aim of this project is to combine our knowledge of the chemistry of both lophine radical systems and cyclophosphazene rings to find elegant synthetic routes which will improve upon the porous properties of hexalophine. This will be done by varying the ring substituents to increase stability of the pores and to improve its gas absorption properties. Three lophine derivatives have been identified as plausible candidates for thid are where two of the phenyl groups on the lophine will be replaced by two thiophene rings and two pyridine rings respectively, with the position of the nitrogen in the pyridine ring being varied depending upon the synthetic pathway (figure 11). We wish to synthesise and fully characterise these derivatives including growing single crystals for structural studies via X-ray crystallography. Also a stoichiometric controlled oxidation of the hexalophine material to its neutral radical/dimer pair is required in order to further investigate the properties of hexa lophine such as the possibility of creating a photochromic material that has light gated pores that open on irradiation with UV light.

Results and discussion 2.0 Hexa-benzaldehyde Synthesis The first step in this synthetic project involved attaching six benzaldehyde units to the phosphazene ring via a P-O oxygen bond. This was achieved by reacting the phosphonitrillic chloride trimer along with 6 equivalents of 4-hydroxybenzaldehyde, potassium carbonate in dry THF (figure 12). The reaction was monitored with 31P NMR which showed completion when only a singlet was present in the spectra indicating full substitution. This produced the compound 1 which was the precursor for many of the subsequent reactions. The reaction gave the desired product in a fairly low yield (45%). Whilst the yield was slightly low the FT-IR showed all of the characteristic absorptions such as C=O (1697cm-1) and CAr-CAr (1585cm-1). 31P NMR was conducted and showed a sharp singlet at 7.08ppm which indicated full substitution on the phosphazene ring as all of the environments are equivalent. 1H NMR was also conducted and show a singlet at 9.87ppm with an integration of 6Hs which was as expected for t he 6 aldehyde protons, two doublets were found in the aromatic region and integrated to 12Hs each which was correct for the number of protons expected. The CHN analysis was almost perfect with less than 0.2% difference from the calculated values, this indicated that the product was of high purity. Mass spectometry also indicated that the desired product had been synthesized as a [M+Na]+ peak was detected at 884. Figure 12 The reaction scheme for the synthesis of 1. 2.1 Synthesis of Hexalophine and Hexalophine derivatives 2.1.0 Using Diketones The synthesis of hexalophine and hexalophine derivatives is important due to their porous properties which can be of great importance in fields such as gas storage and catalysis. The method for attaching six lophine units to the ring was a ring condensation of 1 on the six benzaldehyde units attached to the phosphazene ring using a synthesis based upon Radziszewskis synthesis.1 The product 2 was achieved by reacting 1 along with six equivalents of benzil, ammonium acetate in excess in glacial acetic acid (figure 13). The yield for 2 was quite poor (32%), the FT-IR showed all of the characteristic peaks such as CAr-H (3055cm-1), C=N (1604cm-1) and CAr=CAr (1538cm-1) indicating the desired product had been formed. This was further confirmed by both the 31P and 1H NMR, the 31P NMR showed a singlet at 8.36ppm which indicates full substitution on the phosphazene ring. The 1H NMR showed a singlet at 12.65ppm which had an integration equal to 6Hs which is representative of the 6 imidazole N -Hs, it also showed multiplets in the aromatic region with an integration of 84Hs which is exactly the number of aromatic hydrogens in the desired product. CHN analysis of the product correlated well with the desired structure, especially when three molecules of water were factored into the calculation. It is unsurprising that this compound also contained water due to its porous nature. à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à NH4OAc à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à Acetic acid (6eq.) Figure 13 The reaction scheme for the synthesis of 2. Another reaction designed based upon the ring condensation reaction was the synthesis of 4. This synthesis builds upon the diketone functionality as above, however, in this reaction the R groups of the diketone thenil were thiophene rings as opposed to the phenyl rings of benzil. Thenil like benzil was reacted with 1 and ammonium acetate in glacial acetic acid (figure 14). The yield for this compound, whilst better than 2, was still fairly low (46%). FT-IR showed the characteristic peaks such as CAr-H (3071cm-1), CAr=CAr (1643cm-1) and C=N (1607cm-1) indicating the target molecule had been synthesised. The 31P NMR showed a singlet at 8.26ppm again indicating full substitution. The 1H NMR showed a singlet 12.91ppm with an integration of 6Hs representative of the 6 imidazole N-H hydrogens, it also showed multiplets in the aromatic region with an integration of 60 which was again exactly what was required for the number of aromatic hydrogens, indicating the correct product had been synt hesised. The CHN analysis was close to the theorectical values required especially when four water molecules were factored in, again this is unsurprising as this material like 2 is also expected to be porous. à à à à à à à à à à à à à à à à à à à à à à à NH4OAc à à à à à à à à à à à à à à à à à à à à à à à à à à à à à Acetic acid (6eq.) Figure 14 The reaction scheme for the synthesis of 4. Like thenil and benzil, pyridil is also a diketone where the two R groups are heterocycles, in this case the two heterocycles are pyridine rings. Pyridil was used again with the classical Radziszewski based synthesis to synthesise the compound 5 (Figure 15). The yield for this compound was very low (15%) due to a lot of mass lost upon recrystallization and decomposition upon heating. The FT-IR showed the correct absorptions for the key functional groups such as C=N (1600cm-1) and P=N (1158cm-1) indicating that the target compound had been synthesised. However large OH absorption band (3349cm-1) was also present showing that the product contained a considerable amount of water or ethanol. CHN analysis of the compound showed a vast difference in carbon and nitrogen values when compared to the theoretical values indicating some impurities in the sample. The fact that the product contained considerable amounts solvent would also skew the result of the CHN analysis somewhat. à à à à à à à à à à à à à à à à à à à à NH4OAc à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à Acetic acid (6eq.)

An alternative synthesis of 2 using twelve equivalents of benzaldehyde is illustrated in figure 16. The reaction was left to reflux for 7 days however the 31P NMR showed a multiplet indicating that full substitution had not occurred or a mix of products was present. Unfortunately, this was a reoccurring theme as the failed synthesis of 3 using twelve equivalents of pyridine carboxyaldehyde (figure 17) also showed a multiplet in the 31P NMR. Benzaldehyde (12 eq.) Figure 16 The reaction scheme for and alternative preparation of 2. Carboxyaldehyde (12 eq.) Figure 17 The reaction scheme for compound 3. 2.2 Oxidation of Hexalophine and its derivatives The oxidation of hexalophine is of great interest due to the potential properties it may possess, such as it possessing photochromic properties which may lead to light gated pores. For this oxidation an excess of potassium hydroxide was used to create the anion before 50 equivalents of the classical oxidising agent potassium ferrocyanide (III) were used to perform a one electron oxidation to the radical species 6, a yellow to orange colour change is associated with the formation of the radical species. This radical species quickly dimerises and an orange to yellow colour change is associated with this. Upon irradiation with UV light (365nm) the dimer opens to form two radicals, the colour change associated with this was yellow to purple displaying the photochromic behaviour of this compound (figure 18). The radical species is stable for a number of hours in the solid state unless gentle heating is applied which induces dimerization again and the colour change of purple to yellow is a ssociated with this. FT-IR showed characteristic absorbances of CAr-H (2955cm-1), C-N (1301cm-1) and P=N (1198cm-1) which are present in the desired product. The thiophene hexalophine derivative 4 was also oxidised using the same classical oxidation conditions as above to form its radical species 7. Upon separation the system formed 3 layers, an organic layer, an aqueous layer and a solid substance formed which was soluble in neither. Both the organic layer and solid substance were irradiated with UV light to test for photochromic properties however neither displayed a colour change and thus further testing of this material via UV/Vis spectroscopy is required to determine its nature. Figure 18 A RBF containing the hexalophine dimer and radical, the purple is the radical species, the yellow is the dimer species. 3. Conclusions and further work The aim of this project was to synthesise and characterise functionalised porous organics based upon hexalophine as well as to perform oxidations to the radical species and study their properties such as photochromism. For the most part the aim of the project has been met as two derivatives of hexalophine (4 and 5) and hexalophine (2) itself have been synthesised from simple molecular building blocks and characterised using a range of spectroscopic techniques such as NMR, FT-IR and CHN analysis. The next step in the characterisation of these materials would be to gain crystal structures via x-ray crystallography to show the packing arrangement of these molecules and to prove the existence of pores with in the molecule created from the unique conformation of the phosphazene ring. Additionally, once crystal structures have been gained gas absorption test should be taken to test both the gas uptake properties and selectivity of certain gases. Yields for these experiments were quite low and the aldehyde reactions did not demonstrate full substitution onto the ring, one possible solution would be to try the reaction in a Parr pressure reactor. The oxidation of hexalophine was carried out with great success as the experiment demonstrated the proposed photochromic nature of the material, also the stability of this material with respect to air was very surprising. If possible crystal structures for this material should be obtained in order to investigate further the possibility of light gated pores which when the molecule is in the dimer form are closed but once in the radical form are open. 4.

Baldwins Writing Style in Notes to a Native Son Essay -- James Baldwi
Father and Son: Bad to Regrettable James Baldwin is known to be one of the best essay writers in the twentieth century who wrote on a few topics including race, discrimination, sexuality and most of all his personal experiences. In ââ¬Å"Notes of a Native Sonâ⬠, he uses two main strategies to get his point across. First, he likes to tell a story in a narrative view. Following is normally his analysis of the event. He describes the event and then gives his theory on the matter. By doing this, he grants the reader a chance to decipher the meaning. His interpretation may not be what the readerââ¬â¢s is. He likes to argue and provides the basis for his argument in ââ¬Å"Notes of a Native Sonâ⬠. Throughout the essay he talks about himself and his father, their relationship and how their interactions influence his final feelings toward his father. He also integrates public incidents during those times into the essay. This method presents the reader with an opportunity to understand the race issue at that tim e. This essay is about part of his life. In the beginning he starts with his fatherââ¬â¢s death. It was coincidental that the funeral was on his Baldwinââ¬â¢s nineteenth birthday. Mr. Baldwin, his father, and his wife conceived a child near the end of his life. This child was born a few hours after his death. Here Baldwin presents a binary of life and death, along with other examples, that he executes throughout the essay. In retrospection, he perceives his fatherââ¬â¢s death as a time of sadness and regrets not having a healthier rapport with him and he mentions that his siblings are happy that their father will never come home again. He tells us about the race riots in Detroit and New Jersey and criticizes afterwards. These happenings show the influen... ...art. Baldwin does this using his own personal experiences and tying them into the greater picture of society. All the stories he has expressed in ââ¬Å"Notes of a Native Sonâ⬠can be paralleled with what was going on during that period. He even explained the riots in that sense for the reader. In the first paragraph he states that they drove his father to the cemetery over smashed plate glass (63). This was a result of the hatred and despair felt by the rioters. This visual is a representation of the hatred that had helped to kill his father. The abhorrence that played a role in the death of his father, he feared would do the same to him. The end of the essay shows Baldwin letting go of this hatred and despair. Works Cited Baldwin, James. ââ¬Å"Notes of a Native Son.â⬠1995. James Baldwin: Collected Essays. Ed. Toni Morrison.

Understanding Counter Reformation Essay -- Catholic Church Political R
In order to understand the Counter Reformation one must consider the political factors and motivators behind them as well as the belief factors when examining clashes with the Catholic Church. The Catholic Church during 16th century experienced a reformation that was both politically and belief driven. The Catholic Reformation also known as the Counter Reformation allowed the church to clearly define its position, eliminate unchristian practices and examine its role in world. This paper will address the political motivators of the Counter Reformation, the unchristian practices that fueled corruption and the clearly defined religious concerns of reformers. It will establish that the use of patronage and nepotism ultimately undermined the spiritual piety of the church. Also, the movements that brought spirituality back to the church will be addressed along with those movements that led to separation from church. In detailing the events and character of this era and analyzing the outcomes of reform it will be concluded that the Counter Reformation was the beginning of a stronger church and an end to an era that quite possibly could have led to the dissolution of the Catholic Church. One must understand the political make up of the Catholic Church during this period prior to addressing the reforms to the church. The church was far more than a religious institution. The Catholic Church was supreme in Europe. The power of the pope was total and this was supplemented by the power the Holy Roman Emperor had as temporal defender of the Catholic Church. Even though the church had no determinate territory it was a state. It had a monarch as a pope, it princes in prelates and its subjects in Western Christendom. It had legislative assemblies in ecumenical councils, a constitution in cannon law, and fiscal agency in the Curia. It went to war, negotiated treaties and collected taxies. The church was the Holy Roman Empire with a stronghold throughout Europe. But this would quickly change.(www.History) At the time of the reformation there was great concern that the Old Church with all its history and tradition was in trouble. This concern came from both within the church and outside the church. Protestant and Catholic reformers alike were troubled by the corruption in the church and its inner workings. Reformers saw that the Christian faith had in many ways been taken... ...ounter-Reformation after the Council of Trent a large shift in power occurred in Italy. The Pope who was once a large political figure in Italy had lost his political power but gained Religious Power. Patrons, who had dispersed kin as clergy members all over Italy, also lost power. Their power of placement of clergy was no longer allowed and bishops were given the choice of where clergy members should be located. The Political power that had once belonged to both the Pope and the Patrons had now been given to the sovereigns of the separated nations, who full well knew that in the Council of Trent their power would grow. The Council of was a turning-point in the Catholic Church. There was a certainty in practices and beliefs, the churchââ¬â¢s foundation had been strengthened and there was a base to grow. Catholicism had reestablished itself and it was a force to be dealt with. By the end of the sixteenth century the Catholic Church was still making some serious reforms. This reform movement which extended into the seventeenth century raised moral and educational standards of the clergy. All inspired by the church with a new zeal and morale. One must conclude that reform was needed.

Heroic essay Essay
ââ¬Å"A motherââ¬â¢s happiness is like a beacon, lighting up the future but reflected also on theà past in the guise of fond memories.â⬠The most important and beautiful person in everyoneââ¬â¢sà world is our moms. They are the one who carry us for about 10 months without any sighs orà complaints. Most moms do their best to be a great role model for their children, or even others;à however, some of them can give up so easily that they leave their family scarred for life. Myà mom also belongs to one of these strong, compassionate and understanding moms. She is aà inspiring hero in my life because she is supportive for other family members, and is determinedà for our family to become the best mother.à My mother illustrated her protection as a best assistance through her life to familyà members. Especially for me, I was first-born child for her so that she abetted me anytime andà anywhere I went. For example, when I was in the kindergarten, she left a post-it note on the backà seat of my bicycle every day. She always used to say that ââ¬Å"No matter what bad things happen toà you, I always believe that you can handle it because you are my son. I love you.â⬠My mom wroteà this kind of letter differently every day. It was so shameful at first that I hid it as soon as Ià noticed that there is a tiny yellow paper on the seat. I did not understand why she wrote thisà especially only for me. After she left our family, I started to realize that how important theseà post-it notes were. Although she was not always there for me, and sometimes scolded me, sheà supported, encouraged and took cafà © of me anywhere I went, and anything I did. According toà her last post-it which was 26 days before she left, ââ¬Å"I know you have become much mature now,à but I am not really sure about your inside. Donââ¬â¢t you have to run diligently for the future as thereà have been some delays in your life? You should know that finding out your goal is always first. Ià believe you, and hope you can think and behave more independently.â⬠à My mother was the only person I know who did not give up anything she started orà decided, and sacrificed her life for other family members. My mom used to keep doingà something secretly as the way how my grandma did although there was an obstacle ahead. Forà instance, she did not tell anyone that she became more illness because she was concerned thatà anyone who knew about this would waste of his time worrying about her; she wished that sheà did not want to be othersââ¬â¢ obstacles. While my mom was staying at Korea to cure her illness, sheà once said, ââ¬Å"Do never waste your time tearing because of me. This is my life I chose, and have toà bear. Even though something worse occurs to me, you just have to ignore it and keep moving forà your future.â⬠I could not give up for her as my mom did not give up receiving treatments forà cancer in Korean, although it caused losing her weight a lot, and made her worse, This was aà huge hindrance for my family because if my mom was not able to come to Canada again, weà would not receive our PR, and live here anymore. However, ignoring what her doctorââ¬â¢s saying,à she came back for us to maintain our life in Canada. We all knew that she would not live longerà than at least a year. However, her life was not that long. My mom was determined after she hadà morphine in the hospice. She fell asleep so deeply that she could not move and talk. About a fewà minutes before she died, my mother tried as hard as she could to open her eyes; at last, she didà not open them, but what only she could at that time was crying. Only my family recognized herà tear and perseverance which probably she desired to show us even until the end. We had to say,à although she was determined, and did not want leave us, ââ¬Å"You can go now. We will not botherà you anymore; we have seen that you do not want to give up even now. You just have to rest inà peace. Thank you for everything you have done so far. You were determined enough to becomeà the best mother in the world.â⬠After we said this, she started to give up her life as she did notà want to be an obstacle for our family.à . Can all mothers overcome this circumstance and assist others as what my mother did?à Most moms probably are able to be supportive to their family members and perseverance onà what they have to face. My mom was not only a mother to our family but she also became theà best mother as she showed us her encouragement, support to others and determination what sheà wished to be done. My mother illustrated how much she could help and believe in me no matterà what happens between us; moreover, my mom did not give up what she started although anyà hindrances, which seemed painful, challenging and complicated, occurred to her. Therefore, myà mom is my hero who inspired me as she was abetting and determined.

Is 533 Homework 4
IS 533 HOMEWORK 4 BY AHMET CAN AYKUT (1835917) 1. What is meant by a symptom versus a problem? Relate these ideas to the case. (5 points) In the Intelligence Phase of the Decision Making Process, the decision maker, Elena, attempts to determine whether a problem exists, identify its symptoms, determine its magnitude and explicitly define it. What is described as a problem may only be a symptom, or measure, of a problem. In the case, MMS sales are off by 10 percent, which is the main problem.In the intelligence phase, the CEO calls the Board of Directors to search through the procedures in order to state and classify the problem. She consults Directors to reach the main reason for the problem or to find the real problem which the off-sales are symptoms of it. 2. Why is problem ownership so important? (5 points) A problem exists in an organization only if someone or some group takes on the responsibility of attacking it and if the organization has the ability to solve it.The assignment of authority to solve the problem is called problem ownership. When problem ownership is not established, except for professional employees, there will be an uncertainty of who is responsible to solve the problem and role diffusions/shifting, tendency to avoid form responsibility may occur easily. Problem ownership ensures accountability. 3. Even though the problem was not identified at the end of the intelligence phase, what was? (5 points) Effects were identified and problem ownership was established. Effects of the problem: . Rentals did not increase while the total market did. (CMO) 2. Sales are dropping fastest on primary markets. (CFO) 3. Advertising expenditures are up. GMC Spiders should be a hot seller but they are off by 50 percent. All the new cars came on in on schedule and inventory is OK from CLAUDIA. (CEO) 4. Half of the GMC Spiders are rented although some local agencies set the prices 15 percent less. Rentals are down 8 percent nationally on the other classes of ca rs. (COO) Problem Ownerships: COO assumes the ownership of the problem.CIO will look at the underlying structures and parameters of the forecasting models (for weird economic trends or events); CMO will look into the advertising for external events, trends or reports on the cars that could affect the rentals 4. How was the design phase performed in this case? (10 points) Search and Scanning Procedures: 1. The problem statement has not been clearly stated. So the next step is the investigation of symptoms. 2. A collaboration group is formed with analysts from different departments: Operations and Marketing.Data Collection: 3. Databases of Operational and Economic Data were checked by data mining tools; relationships and assumptions in the forecasting models and RMS were verified; artificial neural networks, clustering analysis algorithms and statistical regression models were also benefited. It was noticed that the neural networks outperformed the regression-based systems a bit. 4. A n information system and marketing group was set up to look into how they could improve the regression-based models with neural networks. 5.An e-meeting was held to decide on what they were going to do next and sharing information. Problem Identification: 6. After the meeting OLAP (Online Analytical Processing) software was used to ââ¬Å"sliceâ⬠multidimensional data. The group noticed a slight inverse relationship with sales and advertising and the followings: a. There is a problem in the distribution. Over half of the cars are in the wrong places. b. GMC Spider was entered to the system as a four-seat compact with two doors. System automatically decides this car ideal for a small family or a single business person.This decision rent well rent in Midwest in the secondary markets but badly in the convention areas where there are men and women who like to rent sporty cars. Problem Statement /Search for Alternatives/Create Models: 7. After further analysis and investigation the real problems and alternatives were stated: a. Data Accuracy Problemââ¬â? Profile of the spider should be changed to a sports car from a compact car. b. Inventory Imbalance Problem-? 15 percent of the fleet should be moved to secondary markets. All the Spiders should be moved from secondary to primary markets.Some of minivans and full-size cars should be moved to secondary markets. Secondary market demand should be pushed by adjusting advertisement. c. Advertising Imbalance-? Customer locations should be identified well to determine what to advertise where. d. â⬠Try before you buyâ⬠campaign should be campaign should be established in the secondary markets. e. In secondary markets people want full size cars. Company advertising features Spider but not the other types of cars. (Advertise backfire problem)-? Substitutes for the Spider should be discounted. f.Florida theme park demand: Florida theme parks are advertising in Europe because the euro is economically stronger than the dollar. -? Advertising in Europe, either with the theme parks or separately, should be increased. 5. The choice phase seemed like a combination of design, choice, and implementation. Is this a problem? (10 points) Both it is a problem and not. It is not a problem because in intelligence, design and choice steps there are feedback points which are Validation of the model, revision of criteria for choice, evaluation of risk and rating the alternatives; verification, testing of proposed solution.It is a problem because the intricate structure of phases may lengthen the choice phase and cause missing the business opportunities. Organizational responses to solution implementations may be slower so that verification and testing of the solution, the sensitivity analysis and plan for implementation may take some time so that phases may become intricate. Also sub optimization and satisficing are potential threats for decision making. 6. The implementation phase seemed to involve el ements of all the phases. Is this a problem? (10 points)It is not a problem because in case of failure all the remaining 3 phases should be revised until the solution is succeeded. Indeed it is hard to implement a solution successfully at the first trial. Making a decision, carrying out a project requires a plan-do-check cycle to get the best. It is a problem because the intricate structure of phases may lengthen the implementation phase and cause missing the business opportunities and not adapting the business environment. 7. How were new problems or opportunities handled as they arose? 10 points) New problems (Data inaccuracy, Inventory Imbalance, Advertising Imbalance) and new opportunities (Discounting substitutes Florida Theme Park Demand and ââ¬Å"Try Before You Buyâ⬠Campaign) were handled by identification, problem ownership and implementation. 8. Why do you suppose some alternatives were either modified or postponed? (10 points) First of all, alternatives should be pr ioritized to decide what to first and which one is more/less important than the others; there is a sequential relation between the alternatives whether the 3rd alternative cannot be achieved before completing the 2nd.In the Decision Making Process in each phase there may be updates and changes that may affect the alternatives until the solution is succeeded. All alternatives cannot be applied simultaneously. 9. How can computerized DSS support the management at each stage of the Simon's Decision Making Model? In which phase is the major contribution of made? Why? (15 points) Decision Support Systems may comprise one or more of the systems mentioned below, which are beneficial in decision making phases. Letââ¬â¢s consider each phase separately: Intelligence Phase:Web tools and sources are useful for environmental scanning. Web browsers provide OLAP, data mining and data warehouses. Data warehouses continuously monitors internal and external information, looking early signs of prob lems and opportunities through an enterprise information portal (i. e. dashboard). Also web mining, Expert Systems, Management Information Systems, Artificial Neural Networks, Genetic Algorithms and other Automatic Decision Making systems also support this phase by identifying relationships among activities and other factors.Geographical Information Systems can be utilized so that the decision maker can determine opportunities and problems in a spatial sense. CRM systems can identify classes of customers to approach with specific products and services. Knowledge Management Systems can be used to identify similar past situations and how they were handled. Group Support Systems can be used to share information and brain storming. Business Activity Monitoring, Business Process Management and Product Life Cycle Management can also provide decision makers the capability of monitoring the current status of operations.Expert Systems can render advice regarding the nature of the problem, it s classification, seriousness and the like. They can advise on the suitability of a solution approach and the likelihood of successfully solving the problem. OLAP tools are excellent tools for routine and ad-hoc reporting. Design Phase: This phase involves generating alternative courses of action, setting criteria for choices and their relative importance and forecasting the future consequences of using various alternatives. OLAP and data mining software are useful in identifying relationships that can be used in models.CRM, Revenue Management, Enterprise Resource Planning and Supply Chain Management Systems can provide models that can test assumptions and scenarios. GSS and cognitive mapping tools can help identifying important issues and options. Risk analysis can also be carried out in this phase. Choice Phase: DSS can support this phase through what if and goal seeking analyses. Different scenarios can be tested for the selected option to reinforce the final decision. KMS can he lp identify similar past experiences.CRM, ERP and SCM systems are used to test the impacts of decisions in establishing their value. ES can be used to assess the desirability of certain solutions and recommend an appropriate solution. GSS can support to lead to consensus in a group decision. Implementation Phase: DSS can be used in implementation activities like decision communication, explanation and justification. BAM, BPM, PLM, KMS, CRM, SCM, ERP and EIS are useful in tracking how well an implementation is working. GSS is useful for team collaboration for implementation effectiveness.ESââ¬â¢ can be used as an advisory system regarding implementation problems. Also they can provide training that may smooth the course of implementation. A CRM Systems can identify classes of customers to get rid of unprofitable customers so that implementation can be focused on profitable customers. Also they report and update internal records, based on the impacts of the implementation so that n ew problems and opportunities can be identified and one or more of the Decision Making Phases can be revisited. In Intelligence phase the major contribution is made. 10.What is the contribution of using Simon's model for rational decision making for the analysis of this case? (20 points) Decision Making is a process that the Decision Maker should know what, why, when, where, how and with whom to start and how to proceed. Defining, categorizing and modeling the steps of decision making and systematically working on them is crucial. Since humans have a limited capacity for rational thinking, we tend to construct and analyze a simplified model of a decision making process. Simonââ¬â¢s model serves as a principal blue print, a basic guide.According to the problem complexity the decision maker can elaborate on the model and improve the phases according to the problem complexity and solution requirements. For example in the design phase normative, descriptive and nonmathematical descri ptive models, scenarios can be benefitted specifically. Simonââ¬â¢s model reminds us that such models may/should be used primarily in the design phase. For example HP developers consider three phases in developing a model (See 2. 1 Opening Vignette: Decision Modeling at HP using Spreadsheets): Problem Framing, Actual Design and Development of the Tools and Handoff.Each of these phases has sub phases like Problem Framing has ââ¬Å"Will analytics solve the problem? â⬠, â⬠Can an existing solution be leveraged? â⬠and ââ¬Å"Is a tool needed? â⬠; Design and Development of the Tools has ââ¬Å"Develop a prototype as quickly as possibleâ⬠, â⬠Build Inside, not black boxes â⬠, etc. HP is a major manufacturer of computers, printers and industrial products. They formed this model to solve their repeating business problems. Simonââ¬â¢s model can also be adapted to HPââ¬â¢s decision modeling processes but their model is much specific and ready-to-use because of their need for agility.
