Free Essays on Malcolm X And MLK Jr Comparison
Both Martin Luther King, Jr. and Malcolm X were publicized as two of the most important figures in the African American Civil Rights struggle during their lifespan. However, both menââ¬â¢s upbringing and their experiences affected their ideology of resolving Americaââ¬â¢s racial struggles. ââ¬Å"Martin King and Malcolm X were shaped by what Vincent Harding has called the ââ¬ËGreat Tradition of Black Protest,ââ¬â¢ a tradition that comprised many variations of nationalism and integrationism.â⬠(Cone, p. 16). Both Martin Luther King, Jr. and Malcolm X came from families that instilled strong family values, religious values, and community involvement. However, during their early development, Martinââ¬â¢s family was able to protect him from the worst experiences of white racism while raising him in the southern United States while Malcolmââ¬â¢s family suffered from the negative effects of racism while raising him mostly in the northern part of the country. Th e difference in their location of development was that Malcolmââ¬â¢s family was affected more by the racial conflict in America than Martinââ¬â¢s family. Due to Malcolmââ¬â¢s experiences it was much harder for him to accept the good values among the general majority of the dominant race of white people in America than the optimistic perception of Martin Luther King, Jr. Martin Luther King, Jr. was born in 1929 and raised in Atlanta, Georgia. Both his father and grandfather were prominent Baptist preachers and leaders in the African American community. The community and its leaders fought against segregation with protest, accommodation, and self-help. The way in which they protested was for equality in an accommodating way of non-violence. It also provided the ideology of the self-help tradition to the African Americans by promoting the value of high achievement in education, business, and morality. Due to the strong influence of the community, religion, and his family values, Martin was able t...

Difference Between Anatomy and Physiology
Difference Between Anatomy and Physiology Anatomy and physiology are two related biology disciplines. Many college courses teach them together, so its easy to be confused about the difference between them. Simply put, anatomy is the study of the structure and identity of body parts, while physiology is the study of how these parts function and relate to one another. Anatomy is a branch of the field of morphology. Morphology encompasses the internal and outward appearance of an organism (e.g., is shape, size, pattern) as well as form and location of external and internal structures (e.g., bones and organs anatomy). A specialist in anatomy is called an anatomist. Anatomists gather information from living and deceased organisms, typically using dissection to master internal structure. The two branches of anatomy are macroscopic or gross anatomy and microscopic anatomy. Gross anatomy focuses on the body as a whole and the identification and description of body parts large enough to be seen with the naked eye. Microscopic anatomy focuses on cellular structures, which may be observed using histology and various types of microscopy. Physiologists need to understand anatomy because the form and location of cells, tissues, and organs are related to function. In a combined course, anatomy tends to be covered first. If the courses are separate, anatomy may be a prerequisite for physiology. The study of physiology requires living specimens and tissues. While an anatomy lab is primarily concerned with dissection, a physiology lab may include experimentation to determine the reaction of cells or systems to change. There are many branches of physiology. For example, a physiologist may focus on the excretory system or the reproductive system. Anatomy and physiology work hand-in-hand. An x-ray technician might discover an unusual lump (change in gross anatomy), leading to a biopsy in which the tissue would be examined on a microscopic level for abnormalities (microscopic anatomy) or a test looking for a disease marker in the urine or blood (physiology). Studying Anatomy and Physiology College biology, pre-med, and pre-vet students often take a combined course called AP (Anatomy and Physiology). This anatomy portion of the course is typically comparative, where students examine homologous and analogous structures in a variety of organisms (e.g., fish, frog, shark, rat or cat). Increasingly, dissections are being replaced by interactive computer programs (virtual dissections). Physiology may be either comparative physiology or human physiology. In medical school, students progress to study human gross anatomy, which involves dissection of a cadaver. In addition to taking AP as a single course, its also possible to specialize in them. A typical anatomy degree program includes courses in embryology, gross anatomy, microanatomy, physiology, and neurobiology. Graduates with advanced degrees in anatomy may become researchers, healthcare educators, or continue their education to become medical doctors. Physiology degrees may be granted at the undergraduate, masters, and doctoral level. Typical courses may include cell biology, molecular biology, exercise physiology, and genetics. A bachelors degree in physiology can lead to entry-level research or placement in a hospital or insurance company. Advanced degrees may lead to careers in research, exercise physiology, or teaching. A degree in either anatomy or physiology is good preparation for studies in the fields of physical therapy, orthopedic medicine, or sports medicine.

Hispanic American Diversity Research Paper Example | Topics and Well Written Essays - 1000 words
Hispanic American Diversity - Research Paper Example Among the major Hispanic groups, Mexican Americans take the major portion. The other groups, Puerto Rican, Cuban, Central or South American, and others have relevant influence in America. These Hispanic or Latino groups, that constitute a major portion among the population of America, are not well considered in the land. This research paper takes a study on Mexicans, Puerto Ricans, Cuban, and central/south Americans and analyses the linguistic, political, social, economic, religious and familial problems of these groups in America. Mexicans: Mexicans are the largest group among the Latino Americans. They contribute about one third of all Hispanic groups: ââ¬Å"as of 2002, about 23 percent of Mexican Americans are English dominant, 26 percent are bilingual, and 51 percent are Spanish dominantâ⬠(Schaefer, 2006, p. 241). It indicates that Mexicans in America use a different language other than what is commonly spoken in America. Many times the Mexicans are denied of their heritag e towards their language- Spanish. The people who speak Spanish are considered to be less able before those who speak English. This language handicap is there among the people of Mexican Americans. The author, Schaefer in the same book makes out the distinction of Mexicans in terms of language. The students who speak Spanish were separated from the other students and bilingual education started with the hope of changing their native language towards English. The main objective of bilingual education turned to teach English as second language (ESL) among the Spanish spoken students of America in a way paved way for discouraging Spanish and establishing the supremacy of English. This language barrier affected the Mexicans in other aspects like political, social, religious and economic spheres. In the political realm many Hispanic members are considered to be non citizens and are denied to vote. Jamieson et al. observe that ââ¬Å"at the time of the 2000 presidential election, 39 perce nt of Hispanics of voting age were non-citizens compared with only 22 percent of White non-Hispanicsâ⬠(Schaefer, 2006, p. 245). This indicates that many of the Hispanic groups are not accepted in America. They are cut off at many levels. Even though much disparity is there, the political notion and involvement of Mexicans in it are on the move. If the American political scenario is watched carefully it can be understood that Democrats have gained much benefits from the Hispanic groups. It was evident in the election 2000. Schaefer says that in the election 2000, George W. Bush gained only 35 percent of their votes whereas Al Gore could gain 62 percent of the Hispanic vote. Most of the Mexicans are Roman Catholics and they consider much priority for religion whereas in America they face the language problems in religion too. The Mass in America is enacted mostly in English and these groups are denied to get actively involve with the Holy Mass. In the matters with economic too t he Hispanic Americans face hardships. Knowledge of English is considered to be a pre requisite for economic growth. In considering the economic levels of the Mexicans it can be stated that the economic level of Hispanic or Latino people are much lower than that of the non-Hispanic people. As the author states: ââ¬Å"over the last twenty years, the proportion of Latinos in poverty has been two or three times that of non-Hispanic Whitesââ¬

Social Construction of Race Essay Example | Topics and Well Written Essays - 250 words
Social Construction of Race - Essay Example Or he might consider himself as European because, though he lived in Asia, he lives as a European still. In this case, the basis for race classification is not physical feature but the cultural values of the person. This indicates that we can never know for sure the race of the person by looking at them. 2. Media is one powerful tool in shaping a societyââ¬â¢s culture, values and preference. At the present time, the media is used by everyone. And we mean every form media, not just television or radio. Nowadays, the power of social media with the dawn of the World Wide Web is clearly visible. It shapes how people think and believe. Media can actually be used to open the perspective of different nations, not just in critical events such as war, economy and politics but also other issues concerning education, women and crime. Because media can now encompass all ages and all races, it can be used to create a venue for open dialogue between different societies in order to create resolu tions for different problems, whether itââ¬â¢s big or small. It can open a nationââ¬â¢s eyes on how their own people believe in but it also can bridge the gap between different nations.

The economic downturn Essay Example for Free
The economic downturn Essay A. Analysis The economic downturn across the United States caused a decrease in funding to performing arts. Thus a proposal to merge the Utah Symphony and Utah Opera companies was made. There have been very few mergers of this type in history. In 1963 the Madison Symphony Orchestra and Madison Opera merged. Also, in 1985, the Chattanooga Opera and Chattanooga Symphony combined. These entities remained combined for a period of time, but ultimately disbanded due to ideologies and methodologies that differed. The Utah Symphony and Utah Opera merger discussion began in December 2001. The cultures of both entities are very different and divergent. This leads to a process to unite the two companies that is a challenging process. A1. Bill Bailey Mr. Baileyââ¬â¢s position is to survive the economic downturn and reduced funding currently affecting the performing arts. He holds the position of board chairman for the Utah Opera Organization. Maslowââ¬â¢s hierarchy of need can help Mr. Bailey influence the behavior of those involved in both organizations by appealing to their interests. Human beings have biological and psychological needs. Biological needs are those needed to survive such as food and sleep. Psychological needs are those that provide positive reinforcement to that individual, such as, success and love. Maslowââ¬â¢s hierarchy of need address the physiological, safety, love, esteem and self-actualization needed to influence human behavior on a basic level (Tay Deiner, 2011). Physiological needs address the desire to find human comfort and reasonable conditions. Safety needs, in regards to work, lead an individual to seek opportunities that provide job security, reasonable compensation, and work conditions that are safe. The love need leads individuals to seek out co-workers to bond with and provide positive daily interactions. The esteem need provides individuals with positive reinforcement and seek job challenges and promotions to help provide this reinforcement. Finally, the self-actualization need provides the individualà the opportunity to participate in decision-making processes and more challenging tasks that may arise. Leaders to motivate individuals can utilize a basic level of Maslowââ¬â¢s hierarchy. The Utah Opera and Utah Symphony both want to continue performing. The economic downturn has affected both entities and Mr. Bailey could appeal to the employees through use of Maslowââ¬â¢s hierarchy. The safety need can be met through continued job security, compensation, and work conditions should a merger go through. The love need or social need could be appealed upon through the use of the same leaders after the merger progresses. The performers would also have the same peers as before and would expand this peer group. The artistic expression and excellence could be preserved through employment of the same artistic leaders post-merger. This would also help with the self-actualization need, since positive reinforcement would be generated for the members of the musical companies. They would have been involved in the decision-making process and the ideals of keeping leaders that had previously been employed by the entities. This would help the musicians remain autonomy and actively seek challenges out to continue with motivation in the self-actualization arena. A2. Scott Parker Mr. Parker is the board chairman of the Utah Symphony. His position is to also survive the economic downturn affecting the performing arts. Mr. Parker must find supporters that are influential and willing to support the merger with the Utah Opera. Mr. Parker has one influential patron who is not willing to lend support for the merger. Mrs. Abravenal does not want the Utah Symphony to lose the prestige that it has found, especially since her husband, Maurice, was maestro of the Utah Symphony for 32 years. Mr. Parker can utilize Alderferââ¬â¢s ERG Theory for motivation. The ERG Theory steps do not rely on each other to work. The ERG Theory consists of 3 distinct parts: existence, relatedness, and growth (Steel Konig, 2006). The existence needs are the desire for physiological well-being. The relatedness needs are the desire to develop relationships with others is meaningful. The growth needs are the desire to reach an individualââ¬â¢s full potential. The ERG Theory need for exis tence and the desire for physiological well being is the main motivator under this theory. A mergerà would help the symphony maintain in existence, since they are financially unstable at this time. Mrs. Abravenal can be educated that support from opera supporters will help keep resources available that are not currently available when the entities are separated. The ERG Theory for relatedness need will be a second motivator under this theory. The human desire for meaningful relationships will provide positive reinforcement to those involved. The supporters of both companies do not want to see them fail and disappear. The passion of the supporters can be utilized and capitalized upon to create a relationship between the two companies. Finally, the ERG Theory for growth needs can provide positive reinforcement for both companies during the merger proposal. The companies are failing separately, but together they could flourish. Resources would be combined and supporters for both would be involved in the growth processes. Mrs. Abravenal could continue her husbandââ¬â¢s vision and help keep the symphony alive and flourishing. A3. Power The future CEO of the combine entities is Anne Ewers. She has both positional power and personal power. She has formal positional power and has the authority to get things accomplished. Ms. Ewers has a legitimate leader role and expects her orders to be complied with. Positive legitimate power involves influencing others to effectively work better whereas negative legitimate power influences others to follow directions due to intimidation or fear of consequences. Ms. Ewers also has referent power. Referent power is the charisma an individual has from his or her own personality (Krietner Kinichki, 2010). Effective leaders have charisma that include positional and referent powers. Effectively using the powers together would allow Ms. Ewers to inspire through her own personality and lead by authority. A3a. Positional Power Ms. Ewers has a proven record in strengthening finances within an organization. She has been a proven and successful leader for many years within the industry. The following examples are characteristics important in positional power: * Centrality ââ¬â Ms. Ewers would need to establish communication roles between the symphony and the opera. The central role would be important in the chain of command, since she would control the flowà of information to both entities. * Flexibility ââ¬â Ms. Ewers would need to be able to adapt to frequently to the work environment. She must be ready to be diverse and produce unique ideas regarding the merger. * Visibility ââ¬â Ms. Ewers must minimize the negative press surrounding the merger. She must capitalize on positive news regarding the merger and be available to communicate the information to the interested parties. Ms. Ewers must be open and available to those who have a vested interest in the companyââ¬â¢s merger. * Relevance ââ¬â Ms. Ewers must be able to provide accurate information that is relevant to the companyââ¬â¢s needs. She must be able to communicate with staff to procure the required information from both companies and prioritize the goal and tasks for both. This should also include integration of the goals and tasks of the merger as well. A3b. Personal Power Ms. Ewers will need to use her referent power to influence those involved in the merger. She will need to gain support from Mr. Lockhart to help influence the merger. Ms. Ewers has a proven record of reducing financial obligation of organizations. She can work with Mr. Lockhart, who has the support of the symphony, to help everyone see the benefits of the merger. Ms. Ewers and Mr. Lockhart can be co-leaders during the merger process. This would help decrease the opposition from the musicians currently seen. A4. Organizational Performance The musicians for the symphony and orchestra have contracts that were hard fought for. A merger would challenge these agreements and the musicians are concerned they would lose their livelihood and artistic autonomy. Thus, a merger is not viewed positively. The symphony and orchestra both have different cultures. They are both run differently and have different expectations. It is clear they cannot be organized into one entity for simplicity. However, this causes potential issues. For instance, if donations were placed in a singular account for both organizations this could cause resentment among the musicians. Also, the musicians may not like answering to one governing board. This could lead to feeling unappreciated and resentment. However, should there be two governing boards, both sides would be represented equally and the musicians would feelà less resentment and more musical autonomy. The biggest challenge would be among pay for the musicians. The musicians for both entities must be paid competitively and fairly. Options for non-salaried positions may be a viable idea. The organizations must be committed to remain impartial and fair during the merger to reduce any animosity. A4a. Recommendations Christine Osborne is the chairwoman for the musicians and has presented their guiding principles to Ms. Ewers. The musician support is important to the organization during the merger. The musicians are dependent upon Ms. Ewers and Mr. Lockhart to become the future leaders within the new organization. Ms. Ewers is an authority in the industry and is the future CEO. Ms. Ewers has a proven record of reducing financial liability within organizations in the industry. She has the power to combine the organizations and utilize a singular vision for excellence in financial and artistic realms. She can use the guiding principles set forth by the musicians to demonstrate her desire to see the organization succeed. Ms. Ewers must first use her referent power to influence the leaders of the Utah Symphony and Utah Opera. She will be the future CEO of the newly formed organization and must demonstrate her vision for the future. This will hopefully provide sufficient motivation to gather support from both entities. Her referent power and vision must continue to provide a passion to the individual management team within the new organization. Ms. Ewerââ¬â¢s passion should extend to all involved and continue within the organization. This passion created within the organization can help develop self-actualization and esteem within all involved. Next, Ms. Ewer will need to focus on the financial stability of the new organization. The economic downturn has decreased the funding to the performing arts. Ms. Ewer will need to address the decreased funding and find additional funding through different avenues. Ms. Ewer is experienced in fund-raising and will be able to promote the organization via this avenue. Also, performer salaries will need to be revised. The musicians have a current agreement in place, but with the merger this would need to be renegotiated. A challenge Ms. Ewer will face is a decrease in salary for the musicians, but she may be able to effectively place emphasis on the new organization and the musicians desire to see it continue, instead of the old organization failing all together.à Finally, Ms. Ewer must put together a management team that will be empowered during the merger. This team must be trustworthy and desire to see the new organization succeed. Ms. Ewer must empower this team to remain pro-active during the merger and to promote the interest of the new organization. A5. Influence Tactics Leaders to promote new ideas often use rational persuasion. Rational persuasion relies on knowledge, reason and facts to encourage someone to follow or endorse an idea (Krietner Kinichki, 2010). Consultation influence is another tactic which allows individuals involved to participate in the decision making process. This gives everyone involved empowerment within the process. Ms. Ewer can utilize consultation influence to involve the musicians in the decision making process and provide empowerment throughout the merger. The decision making process can be enhanced through rationale persuasion. Ms. Ewer can provide background information on both entities and the precarious financial position both faces. This will provide necessary information to rationalize why a merger would be beneficial to both entities. The information provided can be including Ms. Ewerââ¬â¢s vision for the future of the new organization. Ms. Ewer would provide the information necessary to make an informed decision and empower them throughout the merger process. Conclusion The merger between Utah Symphony and Utah Opera requires key individuals be in place that have the knowledge and skills to make it successful. The two boards will need to be pro-active and back leaders Ms. Ewers and Mr. Lockhart. The task will be far from easy, but if prioritized and a determination and passion are unified then the task will be much easier to attain. References Kreitner, R., Kinicke, A. (2010).

Life of Pakistani Villagers :: Essays Papers
Life of Pakistani Villagers The Islamic Republic of Pakistan, a Muslim state, won its freedom from India in 1947. Sixty percent of its population lives in villages. Farmers or herders have jobs in nearby cities or towns. Traditional customs have a strong influence on the life in rural areas of Pakistan, e.g. men have more social freedom than women do. Women avoid contact with men outside their family, and they cover their faces with a veil in the presence of strangers. In the villages, family houses cluster tightly together along narrow alleys, sharing a tank or shallow pond for washing clothes and for watering vegetables and livestock. House walls are mostly built of mud, and they rise to meet thatched roofs. A typical home may have a few pieces of simple furniture with straw mats covering the bare earth floor. A few stone or brick houses shelter the wealthy landlords and merchants. Most of the villagers live in same-styled, mud houses and cooperate with each other in daily life. Pakistani villagers dress themselves very simply as compared to city people. The most common dress for both men and women is a 'Shalwar Kamiz,' which consists of loose trousers worn under a long overblouse. Women wear a 'Doppta' and strictly observe 'purdah' by hiding their faces and private parts of their bodies. Families within the houses are seldom composed of mother, father, and young children. The extended family is more customary in Pakistan. Sons bring their wives to their family home and rear their children there. The eldest father uses the joint earnings of the family members for their support. Farm families work in the fields, raise crops, and tend them. When the crops are ready, they harvest and sell them. During this entire period, women also help in the fields by seeding, watering, and tending the crops alongside the male members of the family. In the extended family, the eldest father supervises the outdoor work while the mother looks after the indoor work. The children help their parents run the house. Villagers normally eat very simple meals consisting of a vegetable curry, a gruel of parched grams or lentils eaten with a bread called 'Chapati' or 'Roti.' The women cook the food which they serve on trays set on the floor. Women eat separately after the male members of the family have taken their meal.

An enjoyable experience
My enjoyable experience is going to Alton towers with school, first of all we came in on the busses and by car in our own clothes then first we went to assembly and then on to registration. We got on the busses to go on our way to Alton towers the journey took about 2 and a half hours to get there when we got there we all got given a ticket too get in the we all went running of I was with Lindsey and Ella first we ran to oblivion it looked very scary but Mr Wynne persuaded me to go on it, oblivion is a ride at Alton towers that you go up a slight hill for about a minute and then when we got to the top, we went round a slight bent in the track and as soon as we got round the bend we thought we were just going to go and plummet but no we were hanging of the edge of the track for 3 seconds which felt like 10 minutes you can feel your heart pounding as you plummet 200 feet into a deep, dark underground hole. After that we found the ride air which on the ride you swoop, soar, dive and most people pretend to be superman you feel like you don't weigh a single pound. Then we went on the ride nemesis this ride is weird, takes you over rivers of blood and rock, the force will leave you breathless as you do the loop de loop. Then on the run again to rita the queen of speed, you might want to hold onto your eyeballs as you're catapulted at tremendous speed when the traffic lights turn green, the train goes from 0 to100 miles per hour in 2.5 seconds. You will come off tingling with excitement and your heart beating so fast. And off again on the run to ripsaw when you take your seat on the ride, no-one is safe from getting wet. The water rises and falls as you swing around in and out of the fountains and we got absolutely soaked. We also went on duel which is a haunted house and you have to shoot ghosts and ghools with a fake plastic gun while you are on a run away train. The flume was the last ride we went on before we had to get on the bus back to school, on the flume you should prepare to get wet, you climb into your bathtub which is like your boat, fly down drops and through waterfalls before finishing off in the power shower and you better watch out for the ducks.

Master and slave operation Essay
Bluetooth devices exist in small ad-hoc network configuration with the ability to operate as either master or the slave; the specification also allows a mechanism for master and slave to switch their roles. The configurations can be single point, which is the simplest configuration with one master and one slave. Multipoint, called a Piconet, based on up to 7 slaves clustered around a single Master. And a third type called a Scatternet, this is a group of Piconets effectively hubbed via a single Bluetooth device acting as a master in one Piconet and a slave in the other Piconet. The Scatternet permits either larger coverage areas or number of devices than a single Piconet can offer. Figure 5 outlines the different master and slave topologies permitted for networks in the standard (see ââ¬Å"Bluetooth: Goodbye Infraredâ⬠). The role of the master is to control the available bandwidth between the slaves, it calculates and allocates how often to communicate with each slave and locks them into the appropriate frequency hopping sequence. The specification describes an algorithm that calculates the hop sequence, the seed being based on the masterââ¬â¢s device address and clock. In addition to hop sequence control, the master is responsible for transmit control by dividing the network into a series of time slots amongst the net members, as part of a Time Division Multiplexing (TDM) scheme. These time slots can consist of data and potentially additional voice traffic i. e. you will always need a data channel before you can add a voice channel. The time slot is defined as 625 à µs and all packet traffic is allocated 1, 3 or 5 slots, grouped together in transmit and receive pairs. Prior to connection some operations such as inquiry, paging and scanning operations may sometimes occur on half slots (see ââ¬Å"Bluetooth: Goodbye Infraredâ⬠). Figure 5: Point to point, Piconet and Scatternet. A. 2. 3 Voice and Data Links. Bluetooth carries communication traffic over two types of air interface links defined as Asynchronous ConnectionLess (ACL) or Synchronous Connection Oriented (SCO). During a connection the links carry voice and data traffic in the time slots and are categorised as either time critical, as used for voice and audio, or high speed non-time critical data with a mechanism for acknowledgement and re-transmission. The first link established between master and slave is the ACL link and carries high speed data that is insensitive to time. It is packet switched, as the data is sporadic in nature, asynchronous, contains asymmetric and symmetric services and uses a polling access scheme. A master may be permitted to have a number of ACL links up to the maximum number of slaves permitted by the specification but only one link is allowed between any two devices (see ââ¬Å"Bluetooth: Goodbye Infraredâ⬠). Once an ACL has been established a SCO link can be created on top of the ACL link. The SCO link is circuit switched; it has symmetric synchronous services and has slot reservation at fixed intervals, making it suitable for time critical data such as voice. The specification restricts the number of SCO links that a master can support to three. Summarising the two types of links: ACL ? Packet constructed of a 72 bit access code, a 54 bit packet header, a 16 bit CRC and Payload data ? Largest data packet is DH5 giving 723. 2 Kb/s as highest data rate in one direction. ? Non time critical data ? Asynchronous ? Packet switched ? Polling access SCO ? Same access code and header as ACL packets ? ARQ (Automatic Repeat reQuest) and SEQ (SEQuence) flags redundant since flow control and re-transmissions do not apply ? Cyclic Redundancy Code (CRC) field is absent? Payload fixed at 30 bytes, with source data of 10, 20 or 30 bytes ? Circuit switched ? Symmetric synchronous services ? Slot reservation at fixed intervals A special case exists that mixes SCO and ACL packets. Known as the Data Voice (DV) packet it carries data and voice on regular intervals like the SCO. The voice data has no flow control or CRC as per SCO packets, whereas the data part of the DV packet has flow control, re-transmission of the data part is permitted and the data part is CRC protected (see ââ¬Å"Bluetooth: Goodbye Infraredâ⬠).

The Articles of Confederation
The Articles of Confederation The first constitution of the United States was known as the Articles of Confederation. The Articles were written in 1977, after independence from Great Britain had been declared and while the American Revolution was in progress. As a constitution, the Articles had a short life. The document was not fully ratified by the states until 1781, and it remained in effect only until 1787. Under the Articles, Congress was the sole organ of government. Also under the Articles the thirteen states had most of the power, which led into many problems. Some of the many problems were that the states taxed import and export between states, no equality in number of votes according to the population, each state can volunteer to pay taxes, and also each state can produce their own money. All these problems led many people to bankruptcy and debt, which they could not pay off. In 1786, there was an uprising in Massachusetts in opposition to high taxes and stringent economic conditions.The Articles of Con ferderation, ratified in 1781. ...Shackled by war debts the government was forced to beg for concessions from each individual state. However, this was merely done on a voluntary basis. The government owed a substantial amount of money, some back-pay to members of her continental army. In a letter from Delegate Joseph Jones he writes George Washington, the "discontent of the army"Ãâà ¦that justice is not intended"Ãâà ¦in complying with the requests [for bonus and back pay]."Ãâà He continues that there is an "inability of Congress to pay their demands unless furnished with the means by the several states."Ãâà The federalists had financial impotence. The writers of these Articles failed to recognize the needs of the national government, blinded by their quest for unbridled individual liberty. In late 1782, the Congress proposed a tax, or impost, on imported goods. However, haunted by the demon they created, the...

Unexpected Origins of Common English Idioms Unexpected Origins of Common English Idioms Idiom is a fixed expression with a figurative meaning. Idioms serve to make language bright and emotional. Very often its better to use an idiom in common speech to illustrate a particular situation, rather than describe it through specific details. The English language is full of weird idioms. Lets look back through history to find the origin of a few of them. To Blackmailââ¬â¢ means to demand money from somebody by means of immoral measures like violence, threats, or the potential to disclose private information. The idiom originated in Scotland around 1600. Scottish farmers paid the rent in silver coins. They were known as white money and spelled like mail or male. Additional payment, which clan chiefs extorted from the farmers using violence and threat was known as blackmail. Later, this word was adopted when around 1900 criminals started to send letters demanding money in order not to reveal personal secrets (Dalton, 2014). The expression: In a nutshell is used to say that some idea is explained in a very precise way with just a few words. The history tells that a long time ago many significant documents were transported inside a shell of a walnut. According to another version, the important documents would often be shortened; thus only vital points were included into handwritten copies (Delton, 2014). In such a way their size also could fit in a nutshell. The meaning of the idiom: Let the Cat Out of the Bag is commonly referred to as a phrase that means an information leak. This expression was coined in medieval times to speak about dishonest market sellers, who cheated naive buyers. Unfair merchants would place a cat in the buyerââ¬â¢s sack instead of a piglet (Delton, 2014). The substitution was discovered only when the sack was taken home and a cat jumped out of it! The expression: Mad as a Hatter is usually used to describe somebody whose actions are absolutely unpredictable. The idiom is well-known from a novel written by Lewis Carroll. But few people realize that it was used even before that. In the Middle Age, felt hats were made with the help of extremely toxic stuff. It was called marcurous nitrate and it often led to trembling in masters body, as if he was mad. Besides that, theres one more fact connected with this phrase. Robert Crab, who lived in the 17th century and gave all his money to poor people, wore a rather bizarre hat and was often called the mad hatter (Delton, 2014). The idiom: Red Herring is used to describe misleading information. However the explanation for the origin of this idiom is closely connected with hunting. Herring was widely caught in Britain during the 18th century. To keep it eatable for some period of time people would salt it and smoke, thus as a result, fish changed its color from gray into a dark brown, and acquired spicy smell. People used the smoked fish during the hunting season; they dragged it along the hunting paths and away from fox holes, so that the dogs could feel the smell of herring instead of fox (Delton, 2014). Using idioms in your everyday communication can show high level of your general knowledge and showcase your sufficient immersion in the cultural background. Just make sure you know the exact meaning of the idioms you use! Dalton. 36 Unexpected Origins Of Everyday British Phrases. 17 Apr. 2014. http://buzzfeed.com/

European Union Law Coursework - Essay Example The latter had been storing several chemical substances, including some of the chemical substances that had been specified in the Directive. In March 2007 Simon was hospitalized for mercury poisoning after eating vegetables from his garden. Mercury had been specified in the Directive. Investigations revealed that this mercury had leaked into Simon's garden from the adjacent Otis Chemicals' warehouse. Directives are the devices through which the European Council implements laws in the Member States of the European Union. Directives harmonise national laws with the European Union laws. The legal systems of the Member States are influenced significantly by the European Community, which governs the interests and rights of the Member States through its own organisations. There exists a unique and sovereign legal system that binds each Member State. This system was developed by means of the several Treaties, which created the EC legislation. One of the main pillars of the EU is the European Court of Justice or the ECJ. The ECJ had interpreted the nature and effect of Treaties, which is known as the doctrine of direct effect. It is a concept which enables aggrieved individuals to seek redressal in national courts if a Member State fails to implement the provision of a directive. The ECJ developed the notion of direct effect. Under this concept, individuals and organisations can use the provisions of the EC Law in a domestic court without having to wait for the Member State to satisfy an obligation which the Member State failed to execute. According to the ECJ, certain requirements have to be fulfilled for the provision of EC Law to gain Direct Effect. According to the notion of direct effect individuals can invoke community law to fulfil the required ratification for enforcement in their national courts. In other words, it empowers individuals to have a control similar to Article 226 EC, which bestows authority on the Commission to initiate proceedings against Member States for breaches. Direct effect permits each and every citizen of the Union to participate in the activities of the Union and it has brought the community into their lives. The legal aspects of direct effect have been established in Van Gend En Loos. The ECJ had held in this case that any individual of the Union can invoke Article 25 EC in order to restrict Member States that imposed additional customs duty on imports and exports and other charges that have equal effects. The Court also held that Article 25 EC was directly effective and individuals could challenge it in their national courts. The Court further held in its decision that individuals may have these rights conferred upon them directly under the provision of the various EU Treaties (Van Gend en Loos v Nederlandse Administratie der Belastingen). In Pubblico Ministerio v Tullio Ratti, criminal proceedings had been initiated, under the national law, against the applicant for the alleged infringement of Italian legislation, which was very stringent in the matter of packing solvents. Ratti resorted to the community directive's direct effect as his defence and the outcome was that a preliminary reference was made to the European Court of Justice. The ECJ placed an estoppel argument with the objective of directly enforcing the directive (Pubblico Ministero v. Tullio Ratti ). The ECJ held that if a directive had
