Geography - Volcanoes Mount St. Helens Eruption 1980 essays

Geography - Volcanoes Mount St. Helens Eruption 1980 essays Volcanoes Mount St. Helens Eruption 1980 Mount St. Helens is situated in North America on the North American plate. It is the peak of the fold mountain range in North America. The fold mountain range was formed around 70 million years ago when a convergent plate boundary, Juan De Fuca Plate (Oceanic Crust), collided with the North American Plate (Continental Crust). The oceanic crust was forced downwards into the mantle causing it to turn into magma. Then the pressure increased in the mantle causing the magma to rise up onto the earths surface. This lead to volcanic eruptions. Many more volcanic eruptions happened at the plate boundary forming Mount St. Helens. Altogether 13 volcano peaks were formed (including Mount St. Helens). This is called the Cascade Range. Mount St. Helens is the youngest and most deadly of the 13 volcanoes in the Cascade Range. The geologists call Mount St. Helens a composite volcano. It is called this because of its steep sides and its construction. It is made from alternate layers of lava flows, ash, and other volcanic debris. Composite volcanoes mainly erupt explosively causing danger to the nearby wildlife and property. Many people live around Mount St. Helens. This is because of the very good fertile soil that surrounds the area. The fertile soil is good for farming. There are also many tourists that visit the area. Travelers from all over the world visit the area to see the Washington based volcano and to admire the large national parks that surround the volcano. There is also a national lake near the volcano called the Spirit Lake. There has only been 1 eruption at Mount St. Helens known to us in this modern era but scientists and geologists can inspect the volcano to see if it has erupted before. They can do this by counting the rings of trees to see how old they are or by inspecting the different layers of alternate rock that made up the volcano Mount St. Helen ...

Netherlands - Geography, Government and History

Netherlands - Geography, Government and History Population: 16,783,092 (July 2010 estimate) Capital: Amsterdam Seat of Government: The Hague Bordering Countries: Germany and Belgium Land Area: 16,039 square miles (41,543 sq km) Coastline: 280 miles (451 km) Highest Point: Vaalserberg at 1,056 feet (322 m) Lowest Point: Zuidplaspolder at -23 feet (-7 m) The Netherlands, officially called the Kingdom of the Netherlands, is located in northwest Europe. The Netherlands borders the North Sea to its north and west, Belgium to the south and Germany to the east. The capital and largest city in the Netherlands is Amsterdam, while the seat of government and therefore most government activity is in the Hague. In its entirety, the Netherlands is often called Holland, while its people are referred to as Dutch. The Netherlands is known for its low lying topography and dikes, as well as for its very liberal government. History of the Netherlands In the first century B.C.E., Julius Caesar entered the Netherlands and found that it was inhabited by various Germanic tribes. The region was then divided into a western portion that was inhabited mainly by Batavians while the east was inhabited by the Frisians. The western part of the Netherlands became a part of the Roman Empire. Between the 4th and 8th centuries, the Franks conquered what is today the Netherlands and the area was later given to the House of Burgundy and the Austrian Habsburgs. In the 16th century, the Netherlands were controlled by Spain but in 1558, the Dutch people revolted and in 1579, the Union of Utrecht joined the seven northern Dutch provinces into the Republic of the United Netherlands. During the 17th century, the Netherlands grew in power with its colonies and navy. However, the Netherlands eventually lost some of its importance after several wars with Spain, France, and England in the 17th and 18th centuries. In addition, the Dutch also lost their technological superiority over these nations. In 1815, Napoleon was defeated and the Netherlands, along with Belgium, became a part of the Kingdom of the United Netherlands. In 1830, Belgium formed its own kingdom and 1848, King Willem II revised the Netherlands constitution to make it more liberal. From 1849-1890, King Willem III ruled over the Netherlands and the country grew significantly. When he died, his daughter Wilhelmina became queen. During World War II, the Netherlands was continuously occupied by Germany beginning in 1940. As a result, Wilhelmina fled to London and established a government in exile. During WWII, over 75% of the Netherlands Jewish population was killed. In May 1945, the Netherlands was liberated and Wilhelmina returned the country. In 1948, she abdicated the throne and her daughter Juliana was queen until 1980 when her daughter Queen Beatrix took the throne. Following WWII, the Netherlands grew in strength politically and economically. Today the country is a large tourist destination and most of its former colonies have gained independence and two (Aruba and the Netherlands Antilles) are still dependent areas. The Government of the Netherlands The Kingdom of the Netherlands is considered a constitutional monarchy (list of monarchs) with a chief of state (Queen Beatrix) and a head of government filling the executive branch. The legislative branch is the bicameral States General with the First Chamber and the Second Chamber. The judicial branch is made up of the Supreme Court. Economics and Land Use in the Netherlands The economy of the Netherlands is stable with strong industrial relations and a moderate unemployment rate. The Netherlands is also a European transportation hub and tourism is also increasing there. The largest industries in the Netherlands are agroindustries, metal and engineering products, electrical machinery and equipment, chemicals, petroleum, construction, microelectronics, and fishing. Agricultural products of the Netherlands include grains, potatoes, sugar beets, fruits, vegetables, and livestock. Geography and Climate of the Netherlands The Netherlands is known for its very low lying topography and reclaimed land called polders. About half of the land in the Netherlands is below sea level polders and dikes make more land available and less prone to flooding for the growing country. There are also some low hills in the southeast but none of them rise above 2,000 feet. The climate of the Netherlands is temperate and highly affected by its marine location. As a result, it has cool summers and mild winters. Amsterdam has a January average low of 33ËšF (0.5ËšC) and an August high of just 71ËšF (21ËšC). More Facts about the Netherlands The official languages of the Netherlands are Dutch and FrisianThe Netherlands has large minority communities of Moroccans, Turks, and SurinameseThe largest cities in the Netherlands are Amsterdam, Rotterdam, The Hague, Utrecht and Eindhoven.

Abstinence Essay Example | Topics and Well Written Essays - 500 words

Abstinence - Essay Example Sexually transmitted diseases are common at present and it is increasing to alarming levels because of the unawareness about the seriousness of such diseases. ‘With abstinence, no barriers or pills are necessary because the person is not having sex. You don't have to be a virgin to practice abstinence. Sometimes people who have been having sex decide not to continue having sex. Even if a person has been having sex, he or she can still choose abstinence to prevent pregnancy and sexually transmitted diseases (STDs) in the future†. Abstinence is difficult to observe in life because of physiological and psychological factors. Sexual desire is an inborn train for every living thing and it is not easy to avoid or remove it. Persons with high will power might be succeeded in avoiding sexual activities. It is difficult for the lay man to refrain from sexual activities. In order observe abstinence, developing the will power is the only way and it should be started at an early stag e itself. In other words, abstinence should be taught in school to prevent "young' pregnancies, STD's and behavioral risks

Email Tracking And News Posting Tracking Essay Example | Topics and Well Written Essays - 750 words

Email Tracking And News Posting Tracking - Essay Example They receive messages and forward them to the intermediate systems that indicate the path between the receiver and the sender. Systems facilitate this activity to determine the actual sender of information, however, it ca n be challenging if the founder of messages covers the suspicious emails and news postings. Email tracking involves screening email delivery to the addressee. It enables the sender to know if the intended recipient received the message, but does not show if the email was opened and read (Pappallardo & Ellen 2005). Outlook, Notes, and Eudora are networked software that enable clients interact with the server. Microsoft office outlook develops a read receipt tracking method, which makes the sender access the receipt request option before sending the email. After sending the message, recipients can also bring to the attention of the sender that the email was received and read. Nevertheless, such email applications do not guarantee the sender receipt request. On then ha nd, news postings indicate on the top of the message significant tracks that show the subject header, the sender, date, and dime sent. With such vital information, tracking of group news becomes easier compared to emails. Postings are public and can be accessed by a significant number of people. Emails are private and more personal than news postings since they are addressed to a specific person or group. News postings audience who visit social networking sites such as face book and twitter. News postings are bulletins for everyone in the network to see. They are useful because they inform friends in the network service without resorting to sending messages individually. However, tracking news becomes challenging since posts are deleted affected ten days while emails are stored in the server for future reading and reference. Therefore, tracking of emails have been shown to be easier than postings. When conducting email tracking, one can use the IP address that the user assigned, whi ch will show the time and date the message was sent (US-CERT 2003). Lastly, in email tracking, one can investigate on behalf of the victim, by sending the original message through copy mailing. At this point, one can send the message as an attachment because for warding replaces the suspect’s information. News postings have group link features that enable the use to sign up until the time when her network shall be back. In networking systems, new postings prove to be the perfect destination for everyone to stay connected. Question 2- IRC crimes The growth of technology has been identified with positive and negative effects. The world has witnessed the abuse of this new system making the society acquire a negative attitude. Child pornography is an ex ample of internet related crime because nude figures are exposed on websites, and when children come across them, they become misguided. Scenes of teenagers involving on sexual acts are posted on the internet. This technology can be accessed by anyone regardless of their age. Such websites have chat conversations, which lure children in to immoral conversations that lead to child abuse. Secondly, carding and phishing describe how fraudsters operate in small and secret channels. They code their messages to prevent people who may come across, and discover their network. Therefore, to track carding and phishing, one should have a peculiar access to IRC network servers. Internet related crime is overlooked when computer crimes come in to discussions. It is seen as a less dangerous compared to other types of crimes. Crimes committed on computers become challenging to track because the society lack s information on this issue. Chat rooms have been made to facilitate chatting and communicating globally (Smith 2004).

Amnesty Essay Example for Free

Amnesty Essay Ever since we started campaigning in 1961, we’ve worked around the globe to stop the abuse of human rights. Amnesty International Goals and strategy AI aims to maintain every humans basic rights as established under the United Nations Declaration of Human Rights. In accordance with this belief, Amnesty works to: †¢Free all Prisoners of Conscience (a POC is a person imprisoned for the peaceful exercise of their beliefs, which differs somewhat from the typical use of the term political prisoner). †¢Ensure fair and prompt trials. †¢Abolish all forms of torture and ill-treatment of prisoners, including the use of the death penalty. End state-sanctioned terrorism, killings, and disappearances. Amnesty International works to combat individual offences (e. g. one man imprisoned for distributing banned literature in Saudi Arabia) as well as more general policies (e. g. the recently overturned policy of executing juvenile offenders in certain U. S. states). Amnesty works primarily on the local level but its forty-year history of action and its Nobel Peace Prize give it international recognition. Most AI members utilize letter-writing to get their message across. When the central Amnesty International organization finds and validates to its satisfaction instances of human rights abuse, they notify each of more than 7,000 local groups as well as over one million independent members, including 300,000 in the United States alone. Groups and members then respond by writing letters of protest and concern to a government official closely involved in the case, generally without mentioning Amnesty directly. Amnesty International follows a neutrality policy called the country rule stating that members should not be active in issues in their own nation, which also protects them from potential mistreatment by their own government. This principle is also applied to researchers and campaigners working for the International Secretariat to prevent domestic political loyalties influencing coverage. Recently, Amnesty has expanded the scope of its work to include economic, social and cultural rights, saying that these concerns had arisen out of its traditional work on political and civil rights. Its 2004 annual report said that it is difficult to achieve sustainable progress towards implementation of any one human right in isolation. AI will strive to assert a holistic view of rights protection. It will be particularly important to do so in relation to extreme poverty, and the human rights issues underlying poverty. [2] As an example it asserts that The right to effective political participation depends on a free media, but also on an educated and literate population. [3]

Sexual Harrassment Essay -- essays papers

Sexual Harrassment Sexual Harassment in the Work Place I. Definition Sexual harassment is a form of sex discrimination that violates Title VII of the Civil Rights Act of 1964. Unwelcome sexual advances, requests for sexual favors, and other verbal or physical conduct of a sexual nature constitutes sexual harassment when submission to or rejection of this conduct explicitly or implicitly affects an individual’s employment, unreasonably interferes with an individual’s work performance or creates an intimidating, hostile or offensive work environment. Sexual harassment can occur in a variety of circumstances, including but not limited to the following: The victim as well as the harasser may be a woman or a man. The victim does not have to be of the opposite sex. In Oncale v. Sundowner, the US Supreme Court decided just this month unanimously ruling that same sex complaints are covered by the law. The harasser can be the victim’s supervisor, an agent of the employer, a supervisor in another area, a co-worker, or a non-employee. The victim does not have to be the person harassed but could be anyone affected by the offensive conduct.  ¨ Unlawful sexual harassment may occur without economic injury to or discharge of the victim. The harasser’s conduct must be unwelcome. It is becoming increasingly rare to find the traditional â€Å"quid pro quo† claim of sexual harassment. The current trend is that of a â€Å"hostile work environment† which can be much more difficult for the employer to address. The EEOC considers the following factors in determining whether or not an environment is sexually hostile: Whether the conduct was verbal or physical or both How frequently it was repeated Whether the conduct was hostile or patently offensive Whether the alleged harasser was a co-worker or supervisor Whether others joined in perpetrating the harassment, and whether the harassment was directed at more than one individual. No one factor controls but an assessment is made based upon the totality of circumstances. II. Regarding Employees It is helpful for the victim to directly inform the harasser that the conduct is unwelcome and must stop. However, a victim of harassment need not always confront his/her harasser directly, so long as his/her conduct demonstrates that the harasser’s behavior is unwelcome. The victim sho... ... the employer be liable if they do or do not encourage or discourage workers from starting relationships that may go bad and cause problems on the job later. These are complicated issues and there are no cut and dry answers. Relationships develop in work areas all the time and always will. On a personal level, before you become involved with someone at work, there are consequences that should be considered. Once more, there have been many successful marriages so it is not necessarily taboo. If you are in a management position, you should be prepared to handle the complications that may result when one of these relationships go bad and effect work performance. For example, Michael’s boss could have handled the situation better. He actually made the decision to transfer Mary. Michael only recommended the transfer. Maybe he should have told Michael he needed to be the one to go. As the political make up of the US Supreme Court changes, and the decisions that determine what constitutes sexual harassment change, Human Resource Managers need to be ready to adapt and change with those swings. Sexual harassment is just one of a myriad of issues that have to be dealt with.

Akamai Teknologi

Why don’t major business firms distribute their videos using P2P networks like BitTorrent? BitTorrent is a protocol that supports the practice of peer-to-peer file sharing and is used for distributing large amounts of data over the Internet. Peer-to-peer  (P2P) networking is a distributed application architecture that partitions tasks or work loads between peers.Emerging collaborative P2P systems are going beyond the era of peers doing similar things while sharing resources, and are looking for diverse peers that can bring in unique resources and capabilities to a virtual community thereby empowering it to engage in greater tasks beyond those that can be accomplished by individual peers, yet that are beneficial to all the peers. Major business firms distribute their videos not using P2P networks like BitTorrent Because Akamai’s service is available in all countries in the world.For example, 85% of the world’s Internet users are within a single network â€Å"ho p† of an Akamai server. Akamai has A wide range of large corporate and government clients: 1 out of every 3 global Fortune 500 companies, 90 of the top 100 online U. S. retailers, all branches of the U. S. military, all of the top Internet portals, all the major U. S. sports leagues, and so on. Akamai has over 73,000 servers on nearly 1,000 networks in 70 countries around the world. In the 2010, Akamai delivers between 15% and 30% of all Web traffic, and hundreds of billions of daily Internet interactions.Akamai’s massive server deployment and relationships with networks throughout the World enable optimal collection of geography and bandwidth-sensing information. Beside that, the Akamai it has an special way which this company is using it to make an easily download’s for the costumers such as videos, music and so on. However, Web sites that are â€Å"Akamaized† can be delivered anywhere from 4 to 10 times as fast as non-Akamaized content. P2P means the sh aring of files between users of the P2P service such as Bittorent or Bitlord. But this also means that all users are actually servers meaning that it is not easy to collect user data.Also major firms might want to use Akamai instead of P2P as it is more reliable, secure and stable. With the underlying infrastructure of the Internet major companies will most likely not benefit from P2P services. Due to the slow loading of websites companies will most likely chose for a web-streamed based content. These content are often saved on a local server and are most likely quicker distributed to their costumers. As a result, Akamai provides a highly accurate knowledge base with worldwide coverage. Customers integrate a simple program into their Web server or application server.This program communicates with the Akamai database to retrieve the very latest information. The Akamai network of servers is constantly mapping the Internet, and at the same time, each company’s software is in con tinual communication with the Akamai network. The result: data is always current. Advertisers can deliver ads based on country, region, city, market area, area code, county, zip code, connection type, and speed. http://en. wikipedia. org/wiki/BitTorrent http://en. wikibooks. org/wiki/The_World_of_Peer-to Peer_(P2P)/Networks_and_Protocols/BitTorrent http://en. wikipedia. org/wiki/Peer-to-peer

Emerging Technology and Its Implications Essay

With the increasing attention being accorded to climate change in the mainstream media these days, there is also an increased attention being given to technological solutions to assist in combating the problem. While such solutions are admirable in that they go above and beyond the usual calls for recycling and the purchase of ‘green’ products – which have been proven to be of trivial impact upon the large scale flaws in systems of production and consumption that characterize industrial modernity – not all of them should embraced uncritically. It is only by subjecting every proposal to save the planet to scrutiny that we can determine a truly sustainable future. One of the ideas that has been receiving increasing currency in environmentalist discussions are large scale planetary ‘technofixes’ collectively referred to as geo-engineering or planetary engineering. These include mirrors in space designed to reflect excess amount of sunlight, artificial trees designed to suck carbon out of the atmosphere, and managed release of sulfates into the atmosphere, and many, many other epic plans to manipulate the ecological fabric of our planet.   Here’s the rub: The term geo engineering is a rather questionable one, as it implies that it has the same kind of empirical or mathematical certainty as engineering when it doesn’t. It smoothens over many of the bumps and curves that characterize our problems and demand creative solutions. In effect, planetary salvation becomes as easy as building a tunnel into a hill or a bridge across a river, when in fact our collective understanding of the systemic impacts is far less than the geo engineering promoters would have us believe. One might as well call it ‘planetary experimentation.’ While the potential benefits proposed are of an epic magnitude, this magnitude would also apply to the potential consequences. Take for example a proposal to suck carbon dioxide into the planet’s oceans by seeding it with iron deposits. Many, including the Scientific Steering Committee of the Surface Ocean-Lower Atmosphere Study (SOLAS) and the World Conservation Union (IUCN) have observed that this has the potential to worsen ocean acidification and lead to catastrophic results for marine ecology: â€Å"The oceans are complex, dynamic, unpredictable and already vulnerable †¦ We need   [to] build their resilience, not undermine it [not] quick fixes to this global problem that may [cause far more long-term harm] than good.† (Gjerde) Additionally, the historical track record of large scale intervention in the name of environmental concern has never been very good to begin with, asserts Alex Steffen of Worldchanging: â€Å"From damming rivers to fighting forest fires to eliminating pests †¦ efforts have †¦ in hindsight [been] so overrun with unintended consequences as to become full-blown disasters, often †¦ worse than the original problems †¦. [And the] cost of errors [increase] with the magnitude of the attempted solution.† (Steffen) Geo engineering is essentially a ‘silver bullet’ solution, one which reduces the political will to creatively retrofit our present lifestyles in such a manner as to be sustainable and environmentally sound, while still being able to enjoy the luxuries of post-industrial advancements. In essence, the tools for a greener world are already here and their downsides are negligible in the face of overwhelming benefits both environmental and societal. In any case, discussion over geo engineering merely provides a distraction from mustering the political will necessary to effect true change. It provides climate change skeptics a justification for political indifference to redressing our present way of life: Why opt for better designed cities, fuel efficient vehicles and profound infrastructural rethinking when we can merely ‘erase’ the effects of our problematic systems? One’s stance on geo engineering is not a question of whether you are a techno utopian or a complete Luddite. However, there is a major distinction to be made between technology that is transparent in agenda, collaborative in nature, and egalitarian in application as well as easy to remedy and technology that is centralized, expensive and difficult to reverse. Between â€Å"Star Wars† –   a missile defense system saddled with so much corruption that does nothing to provide for homeland security – and nuclear power – a promise of perpetual source of energy whose failures wreaked massive consequences – we ought to regard geo engineering with suspicion: dangerous until proven safe. Geo engineering is unnecessary. â€Å"Fixing† the planet in such a manner is turning a blind eye to the way we live: it shows a lack of innovation and political courage that is necessary to the bright green future.   Works Cited Stiles, Lori. â€Å"Space Sunshade Might Be Feasible In Global Warming Emergency.† NASA Earth Observatory. 3 November 2006.

Free Essays on Moores Ford Lynchings

The Long Route Home: On July 25, 1946, two young black couples- Roger and Dorothy Malcom, George and Mae Murray Dorsey-were killed by a lynch mob at the Moore’s Ford Bridge over the Appalachee River connecting Walton and Oconee Counties (Brooks, 1). The four victims were tied up and shot hundreds of times in broad daylight by a mob of unmasked men; murder weapons included rifles, shotguns, pistols, and a machine gun. â€Å"Shooting a black person was like shooting a deer,† George Dorsey’s nephew, George Washington Dorsey said (Suggs C1). It has been over fifty years and this case is still unsolved by police investigators. It is known that there were atleast a dozen men involved in these killings. Included in the four that were known by name was Loy Harrison. Loy Harrison may not have been an obvious suspect to the investigators, but Harrison was the sole perpetrator in the unsolved Moore’s Ford Lynching case. The motive appeared to be hatred and the crime hurt the image of the state leaving the town in an outrage due to the injustice that left the victims in unmarked graves (Jordon,31). Many African Americans lived on farms and tended for white landowners. Bob Hester was a landowner, on this farm the Moore’s Ford Lynching began. On July 14, Roger Malcom followed Dorothy Malcom to Hester’s farm, Roger was arguing with her. According to the original FBI report, Hunter 2 Hester’s son, Barney, told Malcom to leave. As he was leaving a fight broke out between Malcom and Hester. Malcom then pulled out a knife and stabbed Hester in the chest.

Solutions for Challenging Counting Problems

Solutions for Challenging Counting Problems Counting can seem like an easy task to perform. As we go deeper into the area of mathematics known as combinatorics, we realize that we come across some large numbers. Since the factorial shows up so often, and a number such as 10! is greater than three million, counting problems can get complicated very quickly if we attempt to list out all of the possibilities. Sometimes when we consider all of the possibilities that our counting problems can take on, its easier to think through the underlying principles of the problem. This strategy can take much less time than trying brute force to list out a number of combinations or permutations. The question How many ways can something be done? is a different question entirely from What are the ways that something can be done? We will see this idea at work in the following set of challenging counting problems. The following set of questions involves the word TRIANGLE. Note that there are a total of eight letters. Let it be understood that the vowels of the word TRIANGLE are AEI, and the consonants of the word TRIANGLE are LGNRT. For a real challenge, before reading further check out a version of these problems without solutions. The Problems How many ways can the letters of the word TRIANGLE be arranged?Solution: Here there are a total of eight choices for the first letter, seven for the second, six for the third, and so on. By the multiplication principle we multiply for a total of 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 8! 40,320 different ways.How many ways can the letters of the word TRIANGLE be arranged if the first three letters must be RAN (in that exact order)?Solution: The first three letters have been chosen for us, leaving us five letters. After RAN we have five choices for the next letter followed by four, then three, then two then one. By the multiplication principle, there are 5 x 4 x 3 x 2 x 1 5! 120 ways to arrange the letters in a specified way.How many ways can the letters of the word TRIANGLE be arranged if the first three letters must be RAN (in any order)?Solution: Look at this as two independent tasks: the first arranging the letters RAN, and the second arranging the other five letters. There are 3! 6 wa ys to arrange RAN and 5! Ways to arrange the other five letters. So there are a total of 3! x 5! 720 ways to arrange the letters of TRIANGLE as specified. How many ways can the letters of the word TRIANGLE be arranged if the first three letters must be RAN (in any order) and the last letter must be a vowel?Solution: Look at this as three tasks: the first arranging the letters RAN, the second choosing one vowel out of I and E, and the third arranging the other four letters. There are 3! 6 ways to arrange RAN, 2 ways to choose a vowel from the remaining letters and 4! Ways to arrange the other four letters. So there are a total of 3! X 2 x 4! 288 ways to arrange the letters of TRIANGLE as specified.How many ways can the letters of the word TRIANGLE be arranged if the first three letters must be RAN (in any order) and the next three letters must be TRI (in any order)?Solution: Again we have three tasks: the first arranging the letters RAN, the second arranging the letters TRI, and the third arranging the other two letters. There are 3! 6 ways to arrange RAN, 3! ways to arrange TRI and two ways to arrange the other letters. So there are a total of 3! x 3! X 2 72 ways to arrange the letters of TRIANGLE as indicated. How many different ways can the letters of the word TRIANGLE be arranged if the order and the placement of the vowels IAE cannot be changed?Solution: The three vowels must be kept in the same order. Now there are a total of five consonants to arrange. This can be done in 5! 120 ways.How many different ways can the letters of the word TRIANGLE be arranged if the order of the vowels IAE cannot be changed, though their placement may (IAETRNGL and TRIANGEL are acceptable but EIATRNGL and TRIENGLA are not)?Solution: This is best thought of in two steps. Step one is to choose the places that the vowels go. Here we are picking three places out of eight, and the order that we do this is not important. This is a combination and there are a total of C(8,3) 56 ways to perform this step. The remaining five letters may be arranged in 5! 120 ways. This gives a total of 56 x 120 6720 arrangements.How many different ways can the letters of the word TRIANGLE be arranged if the order of the vowels IAE can be changed, though their placement may not?Solution: This is really the same thing as #4 above, but with different letters. We arrange three letters in 3! 6 ways and the other five letters in 5! 120 ways. The total number of ways for this arrangement is 6 x 120 720. How many different ways can six letters of the word TRIANGLE be arranged?Solution: Since we are talking about an arrangement, this is a permutation and there are a total of P( 8, 6) 8!/2! 20,160 ways.How many different ways can six letters of the word TRIANGLE be arranged if there must be an equal number of vowels and consonants?Solution: There is only one way to select the vowels we are going to place. Choosing the consonants can be done in C(5, 3) 10 ways. There are then 6! ways to arrange the six letters. Multiply these numbers together for the result of 7200.How many different ways can six letters of the word TRIANGLE be arranged if there must be at least one consonant?Solution: Every arrangement of six letters satisfies the conditions, so there are P(8, 6) 20,160 ways.How many different ways can six letters of the word TRIANGLE be arranged if the vowels must alternate with consonants?Solution: There are two possibilities, the first letter is a vowel or the first letter is a consonant. If the first letter is a vowel we have three choices, followed by five for a consonant, two for a second vowel, four for a second consonant, one for the last vowel and three for the last consonant. We multiply this to obtain 3 x 5 x 2 x 4 x 1 x 3 360. By symmetry arguments, there are the same number of arrangements that start with a consonant. This gives a total of 720 arrangements. How many different sets of four letters can be formed from the word TRIANGLE?Solution: Since we are talking about a set of four letters from a total of eight, the order is not important. We need to calculate the combination C(8, 4) 70.How many different sets of four letters can be formed from the word TRIANGLE that has two vowels and two consonants?Solution: Here we are forming our set in two steps. There are C(3, 2) 3 ways to choose two vowels from a total of 3. There are C(5, 2) 10 ways to choose to consonants from the five available. This gives a total of 3x10 30 sets possible.How many different sets of four letters can be formed from the word TRIANGLE if we want at least one vowel?Solution: This can be calculated as follows: The number of sets of four with one vowel is C(3, 1) x C( 5, 3) 30.The number of sets of four with two vowels is C(3, 2) x C( 5, 2) 30.The number of sets of four with three vowels is C(3, 3) x C( 5, 1) 5. This gives a total of 65 different sets. Alternately we could calculate that there are 70 ways to form a set of any four letters, and subtract the C(5, 4) 5 ways of obtaining a set with no vowels.

Medical Billing and Coding Research Paper Example | Topics and Well Written Essays - 750 words

Medical Billing and Coding - Research Paper Example In healthcare systems, there are also regulations that govern the way in which the institutions bill their goods and services. In an argument by Kavaler & Spiegel (2003) prior to the creation of billing strategies a healthcare institution should ensure the specifications provided for by the both the W.T.O and legal laws in the country are adhered to. For instance, in some nations all public healthcare institutions are required to give free Tuberculosis funds. In these nations, such a law must be adhered to by all institutions regardless of the preferred billing strategy by an organization. This is different from other business entities which have the freedom to price their commodities. It is a democratic country, business entities are given the freedom to decide on their preferred pricing decisions (Lucas, 2008). However, health institutions are not independent because of their function in the environment. The influence of medical institutions should be regulated in order to promote equality in the provision of the service. Different in the healthcare system pricing is the fact that there are specific quoted prices for drugs. This makes the market an equal opportunity for success for all institutions. Additionally, this fact reduces the competition level of the market. Healthcare institution cannot use the pricing strategy to gain a greatest competitive advantage. However, health care institutions have the opportunity to alter this disadvantage when providing services for patients. The pricing of services is not regulated by any healthy body. Healthcare  institutions only rely on pricing services to satisfy their billing objectives. For this reason, many organizations invest mostly in providing quality services. Additionally, the quality of services provided is directly proportional to the pricing of the service. However, a significant number of healthcare organizations alter the quoted market price by a slim margin to incorporate cost incurred through processes like logistics. Apart from altering the market price, healthcare institutions offer specific purchasing packages.
