Battle of Gettysburg and Union

The Battle of Gettysburg was the turning point of the American Civil War. This is the most famous and important Civil War Battle that occurred on July 1st-3rd 1863 in Gettysburg, Pennsylvania. More importantly Gettysburg was the clash between the two major American Cultures of their time: the North and the South. The Confederacy had an agricultural economy producing tobacco, corn, and cotton, with many large plantations owned by a few very rich white males. These owners lived off the labor of sharecroppers and slaves, charging high dues for use of their land.The Southern or Confederate Army was made up of a group of white males fighting for their independence from federal northern dictates. The Union economy was based on manufacturing, and even the minorities in the North were better off than those in the South most of the time. The Northern politicians wanted tariffs, and a large army. The Southern plantation owners wanted the exact opposite. The South was fighting against a governm ent because they thought they were being treated unfair. An analysis of the Battle of Gettysburg reveals one challenge facing the Union and the Confederacy was unjustified taxes and slavery.The battle began on July 1, 1863. The Battle of Gettysburg began when the Confederate cavalry ran into the Union horsemen. Both sides then called for backup. The Confederates’ back up arrived first; they now had twice as many men as the union. Soon after Union General John Reynolds arrived, he was shot in the back of the head and killed instantly. They confederates drove the Union south of town. Everyone set up for battle and waited until day two. The excitement of the battle began on day two, July 2, 1863. By morning, 150 thousand Union and Confederate troops had joined at little Pennsylvania town.The Confederates occupied a line west of the Emmetsburg Road, along the Seminary Ridge. While the Union men waited along Cemetery Ridge. The union had an advantage because; Cemetery Ridge was a somewhat more elevated. On day two the Union won overall. The following events occured on day two: Little Round Top, Devil’s Den, Battle of the Wheatfield, Battle of the Peach Orchard, and the Battle of Cemetery Hill. The number of casualties in the Battle of Gettysburg was enormous compared to any war. The casualties of just day two are the union at 8,750 and the confederate at 6,500. One of the major events from day two was the Devil’s Den.It is unique because the Confederate won which was very uncommon. â€Å"Devil’s Den is the name given to a ridge strewn with large boulders south of the town of Gettysburg, Pennsylvania, and about 500 yards west of Little Round Top on the Battle of Gettysburg battlefield. The origin of the name is uncertain. On July 2, 1863, the second day of the Battle of Gettysburg, the area around Devil’s Den saw intense fighting as part of General Robert E. Lee’s flank attacks, when Lieutenant General James Longstreet†™s Confederate corps attacked the divisions of Major General Daniel Sickles’ III Corps of the Army of the Potomac.Some 5,500 Confederates from Major General John Bell Hood’s division ultimately captured Devil’s Den from 2,400 defenders drawn from Major General David Bell Birney’s division. It was one of the few Southern successes in that day’s fighting. Total casualty estimates are over 800 for the Union, more than 1,800 among the Confederates. † (The Devil's Den) This event/location is also significant because Major General John Bell Hood was wounded and was forced to yield his command. There were two main locations of the Battle of Gettysburg, they were Little and Big Round Top.Little Round top is the smaller of the two. It is located between Taneytown and Emmetsburg roads. At the time of the battle â€Å"it was known locally by various names including Sugar Loaf. † (Little Round Top) Major General Governor K. Warren, chief enginee r of the Army of the Potomac, rushed troops to Little Round Top; they arrived minutes before the Confederates did. The 20th Maine Regiment charged late in the battle, which foiled a flanking attempt by the 15th Alabama. Overall the battle at Little Round top the union won. The final day of battle was on July 3, 1863.Both the Confederates and the Union had their plains of winning the battle. Robert E. Lee from the Confederate side decided they should charge into the middle of the Union line and break the line into two. When Robert E. Lee decided on the Plan to charge through the middle of the Union line Major General George Pickett knew it would not succeed. He tried to talk Lee out of it, but Lee instructed Pickett to charge. Major Picket followed these orders. This is known as Pickett’s Charge. The charge took place â€Å"between Seminary and Cemetery ridges, Gettysburg battlefield, Pennsylvania. (Pickett’s Charge)While all of this was occurring â€Å"General Slocum attacked Confederate troops at Culp’s Hill to regain territory loss the previous day. This fight lasted for a good 8 hours finally forcing the Confederates to retreat off of Culp’s Hill. † (Gettysburg Day Three) In the end the Union won. â€Å"Culp’s Hill was the right-most flank of the â€Å"fishhook† line formed by Union Army troops during the Battle of Gettysburg and saw fighting all three days of the battle. Culp’s Hill has two rounded peaks with a narrow saddle between them.Although heavily wooded and unsuitable for artillery, the main peak of Culp’s Hill rises substantially above the surrounding landscape, at a little over 200 feet above the town of Gettysburg and 127 feet higher than Cemetery Hill. With Baltimore Pike, critical for Union Army supplies and preventing Confederate advance on Baltimore or Washington, DC, to the east and Confederates approaching from Rock Creek to the west, Culp’s Hill was critical to Union strategy. † (Culp’s Hill) The Union had two main places throughout the three days they were located. Cemetery Hill was the site of Army’s weaponry.The hill is north of Cemetery Ridge. The defense of the Union line begins to â€Å"to turn east to form the â€Å"fishhook† line to Culp’s Hill. † (Cemetery Hill) Cemetery Ridge is about two miles long and 40feet above surrounding land. The Confederate Army launched attacked the Union many times at Cemetery Ridge. These attacks took place on day two and three. On each attack they were forced to fall back on each occasion. On November 19, 1863 Abraham Lincoln gave a famous speech called The Gettysburg Address. The speech was a dedication to the Soldier’s National Cemetery.Soldier’s National Cemetery is a cemetery for Union soldiers killed at the Battle of Gettysburg. The speech is as follows: â€Å"Four score and seven years ago our fathers brought forth on this continent, a new natio n, conceived in Liberty, and dedicated to the proposition that all men are created equal. Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live.It is altogether fitting and proper that we should do this. But, in a larger sense, we cannot dedicate — we cannot consecrate — we cannot hallow — this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced.It is rather for us to be here dedicated to the g reat task remaining before us — that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion — that we here highly resolve that these dead shall not have died in vain — that this nation, under God, shall have a new birth of freedom — and that government of the people, by the people, for the people, shall not perish from the earth. † (Gettysburg Address Text) The actual main speaker of the night was Edward Everett. He spoke for two hours all from memory. Finally, the Battle of Gettysburg was won by the Union.The war didn’t end slavery, but instead furthered the advancement in ending slavery. Years after the war in 1865 the 13th amendment was adopted and slavery was then on out illegal. The war was not just about slavery, but also about taxes. The higher taxes came about to the south when Lincoln needed money. All in all the Battle of Gettysburg is the bloodiest war and had the most causalities.

Library vs. Internet

COMPUTERIZED LIBRARY SYSTEM: Foreign Study Chapter I Project Overview Introduction Nowadays, in a highly technological society, human productivity is made more efficient through the development of electronic gadgets. Now, with the advent of such modernization in education, one way to globalize the process of research is to realize that technology is advancing at an incredibly fast pace. Computers are not confined to being used for entertainment but its role in education is also vast. Library is derived from the old French term â€Å"librairie† which means â€Å"a collection of books. † Reading materials in school are stored in libraries.Library is a place in which books and related materials are kept for use but not for sale. It is also organized for use and maintained by a public body, an institution or a private individual. In addition, it is a place in which we get information in any format and from many sources. The librarian has to keep the room neat so that it is conducive for learning. The librarian is also the person who is liable for monitoring all the books that are borrowed and returned by the borrowers. http://www. studymode. com/essays/Computerized-Library-System-427957. html Local Studies About Library System- A Sample ThesisLibrary systems, comparisons and contrasts. For the children of today, going to the library,  searching  through the card catalogue to look for books on topics they need to research on is quite archaic! However, many of us still remember how time consuming this was. The kids of today certainly have it easy. Imagine getting all the information you need with one-click of your mouse!?! An  integrated library system  (ILS), also known as a  library management system  (LMS), is an  enterprise resource planning  system for a  library, used to track items owned, orders made, bills paid, and patrons who have borrowed.An ILS usually comprises a  relational database, software to interact with that datab ase, and two  graphical user interfaces  (one for patrons, one for staff). Most ILSes separate software functions into discrete programs called modules, each of them integrated with a unified interface. Examples  of modules might include:  §Ã‚  Ã‚  acquisitions (ordering, receiving, and  invoicing  materials)  §Ã‚  Ã‚  cataloging  (classifying and indexing materials)  §Ã‚  Ã‚  circulation (lending materials to patrons and receiving them back)  §Ã‚  Ã‚  serials  (tracking  magazine and  newspaper  holdings)  §Ã‚  Ã‚  the  OPAC  (public interface for users)Each patron and item has a unique ID in the database that allows the ILS to track its activity. Larger libraries use an ILS to order and acquire, receive and invoice, catalog, circulate, track and shelve materials. Smaller libraries, such as those in private homes or  non-profit organizations  (like churches or synagogues, for instance), often forgo the expense and maintenance required to run an ILS, and instead use a library computer system. (Wikipedia) Automation of the catalog saves the labor involved in re-sorting the card catalog, keeping it up-to-date with respect to the collection, etc.Other tasks which are now automated include checking-out and checking-in books, generating statistics and reports, acquisitions and subscriptions, indexing journal articles and linking to them, as well as  tracking  interlibrary loans. Since the late 1980s,  windowing systems  and multi-tasking have allowed the integration of business functions. Instead of having to open up separate applications, library staff could now use a single application with multiple functional modules.As the  Internet  grew, ILS vendors offered more functionality related to computer networks. As of 2009  major ILS systems offer web-based portals where library users can log in to view their account, renew their books, and authenticate themselves for access to  online databases. (Wikipedia) In r ecent years some libraries have turned to major open source ILSs such as  Koha  and  Evergreen. Common reasons noted were to avoid vendor lock in, avoid license fees, and participate in software development. Librarytechnology. rg does an annual survey of over 1,500 libraries and noted in 2008 2%[3]  of those surveyed used open source ILS, in 2009 the number increased to 8%[4]  and in 2010(most recent year available) 12%[5]  of the libraries polled had adopted open source ILSs.

Training on site and in UK has been provided by IME to the s taff of the network. Staff expertise on the use of all the modules of TINLIB running on UNIX has been brought to a level where the staff can now confidently train others and maintain the system. Online support via the Internet is also provided by IME upon request. The choice of a common library system was decided by the technical committee of the network libraries to have a uniform platform, training programs, import profiles, etc. cross the network and for ease in establishing a user group/systems administration group. TINLIB was chosen because it met the systems specifications prepared by the technical working group, and had favorable references from users. Additional features which gave it an edge over other systems is its utilization of hypertext techniques, client-server architecture, and ability to import and export data from any of the databases existing in the network libraries. The library directors and heads are under tremendous pressure to continue and expand the networke d services.Four of the services which need to be implemented immediately are:          1) the creation of a union catalog for books, audio-visual, serials and Filipiniana articles and researches;          2) access to CD-ROM abstracts and indexes and full text journals and references from any site on the network, subject to copyright and licensing agreement with suppliers and publishers;          3) development of networking navigation tools and training programs; and          4) building of sufficient monetary resources and/or commitment of university officials to allocating sufficient funds for the maintenance of the network. ) transforming the College of Science library into a National Science Library and Information Center to widen the scope of its services http://www. studymode. com/essays/Library-Foreign-Literature-906068. html

AIMS & OBJECTIVES Objectives To investigate Free Convection and Radiation 1. Determine the emissivity (? ) of an element experimentally. . Determine the Heat transfer coefficients by free convection Theory Natural Convection: Heat transfer through circulation of fluid due solely to gravity Forced Convection: Heat transfer through circulation of fluid due to forced fluid movement (fan, pump, etc. ) Radiation: Heat transferred by surface photon emission, typically only significant at T>>Room Temp. EXPERIMENT Apparatus Used Figures 1 below shows the vacuum pump vessel and measuring equipment used The apparatus consisted of a heated element which was suspended inside a [pressure vessel.The air pressure in the vessel was varied by the use of either a bleed valve or a 240v vacuum pump. The heat input to the e element was varied by up to 10W, the max working temp was not to exceed 200 °C and maintained at that temperature or less throughout the experiment. The heat, power Input, the element, vessel temperatures and the air pressure inside the vessel was determined by the instruments provided for the experiment Procedure 1) Using the wall mounted barometer the atmospheric pressure was 1018 mB The gauge gives a reading of gauge pressure (diff between the pressure inside the vessel and pressure outside the vessel)Absolute pressure (P) = pressure gauge reading + atmospheric pressure (mB) 2) Pressure reduced to 2mB and input voltage set to 8. 21 volts. 3) Observations and readings taken after 15 mins to allow system to stabilise and readings tabulated. 4) Item 3 repeated with Vacuum pressure reduced by 12, 60, 200, 500 and then finally with the bleed valve fully open tabulated as before. 5) Bleed valve was then fully opened to allow the pressure inside the vessel to meet atmospheric pressure and readings tabulated. RESULTS, CALCULATIONS, OBSERVATIONS & CONCLUSIONSObservations During Tests The initial observations were of the temperature, vacuum pressure and vessel pressures in relation to the inside diameter of the vessel and element assembly.

Natural convection is more prevalent at lower temperatures whereas radiation is more prevalent at higher temperaturesPossible Sources of error: †¢ conduction from the heated cylinder to its housing tube †¢ possible changes in ambient temperature †¢ Variations in surface temperature Heat Transfer by Convection and uses Heat typically does not flow through liquids and gases by means of conduction. Liquids and gases are fluids; their particles are not fixed in place; they move about the bulk of the sample of matter. The model used for explaining heat transfer through the bulk of liquids and gases involves convection. Convection is the process of heat transfer from one location to the next by the movement of fluids.The moving fluid carries energy with it. The fluid flows from a high temperature locat ion to a low temperature location. [pic] (Images courtesy Peter Lewis and Chris West of Standford's SLAC. ) To understand convection in fluids, Consider the heat transfer through the water that is being heated in a pot on a stove. The source of the heat is the stove burner. The metal pot that holds the water is heated by the stove burner. As the metal becomes hot, it begins to conduct heat to the water. The water at the boundary with the metal pan becomes hot. Fluids expand when heated and become less dense.So as the water at the bottom of the pot becomes hot, its density decreases. The differences in water density between the bottom of the pot, and the top of the pot results in the gradual formation of circulation currents. Hot water begins to rise to the top of the pot displacing the colder water that was originally there. And the colder water that was present at the top of the pot moves towards the bottom of the pot where it is heated and begins to rise. These circulation current s slowly develop over time, providing the pathway for heated water to transfer energy from the bottom of the pot to the surface.Convection also explains how an electric heater placed on the floor of a cold room warms up the air in the room. Air present near the coils of the heater warm up. As the air warms up, it expands, becomes less dense and begins to rise. As the hot air rises, it pushes some of the cold air near the top of the room out of the way. The cold air moves towards the bottom of the room to replace the hot air that has risen. As the colder air approaches the heater at the bottom of the room, it becomes warmed by the heater and begins to rise. Once more, convection currents are slowly formed.Air travels along these pathways, carrying energy with it from the heater throughout the room. Convection is the main method of heat transfer in fluids such as water and air. It is often said that heat rises in these situations. The more appropriate explanation is to say that heated fluid rises. For instance, as the heated air rises from the heater on a floor, it carries more energetic particles with it. As the more energetic particles of the heated air mix with the cooler air near the ceiling, the average kinetic energy of the air near the top of the room increases.This increase in the average kinetic energy corresponds to an increase in temperature. The net result of the rising hot fluid is the transfer of heat from one location to another location. The convection method of heat transfer always involves the transfer of heat by the movement of matter. The two examples of convection discussed here – heating water in a pot and heating air in a room – are examples of natural convection. The driving force of the circulation of fluid is natural – differences in density between two locations as the result of fluid being heated at some source. Some sources introduce the concept of buoyant forces to explain why the heated fluids rise. We will not pursue such explanations here. ) Natural convection is common in nature. The earth's oceans and atmosphere are heated by natural convection. In contrast to natural convection, forced convection involves fluid being forced from one location to another by fans, pumps and other devices. Many home heating systems involve force air heating. Air is heated at a furnace and blown by fans through ductwork and released into rooms at vent locations. This is an example of forced convection.The movement of the fluid from the hot location (near the furnace) to the cool location (the rooms throughout the house) is driven or forced by a fan. Some ovens are forced convection ovens; they have fans that blow heated air from a heat source into the oven. Some fireplaces enhance the heating ability of the fire by blowing heated air from the fireplace unit into the adjacent room. This is another example of forced convection. Heat Transfer by Radiation A final method of heat transfer involves radiation. R adiation is the transfer of heat by means of electromagnetic waves.To radiate means to send out or spread from a central location. Whether it is light, sound, waves, rays, flower petals, wheel spokes or pain, if something radiates then it protrudes or spreads outward from an origin. The transfer of heat by radiation involves the carrying of energy from an origin to the space surrounding it. The energy is carried by electromagnetic waves and does not involve the movement or the interaction of matter. Thermal radiation can occur through matter or through a region of space that is void of matter (i. e. , a vacuum).In fact, the heat received on Earth from the sun is the result of electromagnetic waves traveling through the void of space between the Earth and the sun. All objects radiate energy in the form of electromagnetic waves. The rate at which this energy is released is proportional to the Kelvin temperature (T) raised to the fourth power. Radiation rate = k†¢T4 (Images courte sy Peter Lewis and Chris West of Standford's SLAC. ) The hotter the object, the more it radiates. The sun obviously radiates off more energy than a hot mug of coffee. The temperature also affects the wavelength and frequency of the radiated waves.Objects at typical room temperatures radiate energy as infrared waves. Being invisible to the human eye, we do not see this form of radiation. An infrared camera is capable of detecting such radiation. Perhaps you have seen thermal photographs or videos of the radiation surrounding a person or animal or a hot mug of coffee or the Earth. The energy radiated from an object is usually a collection or range of wavelengths. This is usually referred to as an emission spectrum. As the temperature of an object increases, the wavelengths within the spectra of the emitted radiation also decrease.Hotter objects tend to emit shorter wavelength, higher frequency radiation. The coils of an electric toaster are considerably hotter than room temperature an d emit electromagnetic radiation in the visible spectrum. Fortunately, this provides a convenient warning to its users that the coils are hot. The tungsten filament of an incandescent light bulb emits electromagnetic radiation in the visible (and beyond) range. This radiation not only allows us to see, it also warms the glass bulb that contains the filament. Put your hand near the bulb (without touching it) and you will feel the radiation from the bulb as well.Thermal radiation is a form of heat transfer because the electromagnetic radiation emitted from the source carries energy away from the source to surrounding (or distant) objects. This energy is absorbed by those objects, causing the average kinetic energy of their particles to increase and causing the temperatures to rise. In this sense, energy is transferred from one location to another by means of electromagnetic radiation. The image at the right was taken by a thermal imaging camera. The camera detects the radiation emitte d by objects and represents it by means of a color photograph.The hotter colors represent areas of objects that are emitting thermal radiation at a more intense rate. Conclusion The experiment described above provides a convenient method whereby You may investigate the different processes that contribute to cooling in a standard laboratory experiment. In particular, the measurements obtained to enable you to clarify the relative contributions from convection and radiation. Examples of Free – Natural Convection Heat transfer by natural convection occurs when a fluid is in contact with a surface hotter or colder than itself. As the fluid is heated or cooled it changes its density.This difference in density causes movement in the fluid that has been heated or cooled and causes the heat transfer to continue. There are many examples of natural convection in the food industry. Convection is significant when hot surfaces, such as retorts which may be vertical or horizontal cylinders , are exposed with or without insulation to colder ambient air. It occurs when food is placed inside a chiller or freezer store in which circulation is not assisted by fans. Convection is important when material is placed in ovens without fans and afterwards when the cooked material is removed to cool in air.Convective heat transfer is a mechanism of heat transfer occurring because of bulk motion (observable movement) of fluids. Heat is the entity of interest being advected (carried), and diffused (dispersed). This can be contrasted with radiative heat transfer, the transfer of energy through electromagnetic waves. Heat is transferred by convection in numerous examples of naturally occurring fluid flow, such as: wind, oceanic currents, and movements within the Earth's mantle. Convection is also used in engineering practices to provide desired temperature changes, as in heating of homes, industrial processes, cooling of equipment, etc.The rate of convective heat transfer may be impro ved by the use of a heat sink, often in conjunction with a fan. For instance, a typical computer CPU will have a purpose-made fan to ensure its operating temperature is kept within tolerable limits. Typical Examples of Heat Transfer CONDUCTION: Heat conduction is an essential and commonplace part of our daily lives, in industry, and in nature. Whenever heat needs to be transferred through an opaque substance, the transfer must be by conduction.In a hot-water heating system, for example, heat from burning fuel is transferred by conduction through the iron or steel of the boiler to heat the water. Heat from a burner on a stove is conducted through the bottom of utensils to cook food. In nature, the surface of the earth is heated by the sun, and some of this heat is conducted to deeper layers of the soil during the day and back to the surface at night-the varying ability of different kinds of soil and water to absorb and conduct heat received from the sun has a profound effect on local and worldwide weather and climate. Examples Touching a stove and being burned -Ice cooling down your hand -Boiling water by thrusting a red-hot piece of iron into it CONVECTION: Free, or natural, convection occurs when bulk fluid motion (steams and currents) are caused by buoyancy forces that result from density variations due to variations of temperature in the fluid. Forced convection is a term used when the streams and currents in the fluid are induced by external means—such as fans, stirrers, and pumps—creating an artificially induced convection current. Examples -Hot air rising, cooling, and falling (convection currents An old-fashioned radiator (creates a convection cell in a room by emitting warm air at the top and drawing in cool air at the bottom). RADIATION: – Heat from the sun warming your face- Heat from a lightbulb – Heat from a fire – Heat from anything else which is warmer than its surroundings. – Gas chambers in Jet engines – Circulation Boiler Furnaces Industrial example Radiation Heat transfer generally occurs in Higher temperature applications within processes with furnace temperatures above about 2200 °F (1200 °C). They usually have furnaces which use combustors such as in the metals, minerals, and waste incineration industries.In general, the dominant heat transfer mechanism in those industries is thermal radiation. This is in contrast to lower temperature applications where both radiation and forced convection are often important.

After completion of the certified degree program, the engineer must satisfy the exam requirements and have work experience before being certified as a professional engineer. Certification means that the certified engineer may prepare, sign and submit engineering plans and drawings to a public authority for approval while abiding by the code of ethics set by the certifying bodies. The field is concerned with rocks, soils, highways, sewers and underground water systems, foundations of buildings and bridges. The professional engineer studies technical information obtained from material testing, sciences of geology and hydraulics to design foundations and structures while ensuring safety and economy of the project. This discipline is concerned with the science of waste management, water purification, cleaning of contaminated areas, industrial ecology and reduction of pollution. Policy makers rely on technical data obtained through environmental engineering to make environmentally related decisions. It deals with the management of quality and quantity of underground water and above ground water resources, like rivers, lakes and streams. It involves analyzing geographical areas to forecast the quantity of water that is likely to flow into and out of a water source. It deals with the design of structures to ensure that they are economical, safe for the users and serve the desired function. Loads acting on the structures and the stresses created due to these loads are identified in order to design a structure that withstands these loads. The structures include bridges, tunnels, highways, steel

The Enlightenment by Immanuel Kant Essay Example | Topics and Well Written Essays - 1500 words

The Enlightenment by Immanuel Kant - Essay Example This implies that in deed it was the enlightenment age. He added that a prince ought to indicate clearly that his duty is not to dictate anything about religious subjects but he should leave them completely free. According to Immanuel, enlightenment’s main point is the emergence of men from self-imposed nonage. Primarily the nonage is in religious matters since rulers are not interested in playing the guardian in their subjects, the sciences and arts. He also added that nonage in religion is the most harmful and dishonorable. According to Immanuel only, enlightened man can give people freedom to argue as much as they like and about what they like but obey (Porter, 2001).Jerusalem: or on religious power and Judaism by Moses Mendelssohn One of the most political tasks, according to Moses, was balancing religion and state, civil and ecclesiastical constitution as well as churchly and secular authority. This is because they did not but they just became burdens on social life and weighed down its foundation rather than upholding it. Men had strived in solving it and enjoyed settling it practically instead of solving it theoretically (Jacob, 2001). Some of them thought of separating these different societal men’s relations into moral entities and assign every province specific duties, rights, properties and powers. The extent of various boundaries and provinces could not, however, be fixed accurately.According to Moses, disposition has an advantage of being consistent. He terms it to have answer to every question.

Racism Essay Example | Topics and Well Written Essays - 750 words

Racism - Essay Example Two of these stereotypes are the idea that Chinatown and Chinese people are somehow immoral and dirty. A lot of the background of these and other racial ideas has to do with a shift in the thinking of the nineteenth century "from ethnocentrism to a radical biological determinism," where people tried to come up with scientific proof that one race was somehow better than another (Anderson 585). These resulted in stereotyping of other races and also, such as in the case of Chinatown, the splitting apart from mainstream society of other races so that their lesser qualities would not "contaminate" white society (Anderson 585). Anderson quotes a secretary of state from 1885 in Canada who says that Chinatown is "attended with evils" and that "because of their habits of lodging crowded quarters and accumulating filth, is offensive if not likely to breed disease" (Anderson 586). This idea continues to grow in the period from then until the 1920s. Darwin's ideas and other scientific advances w ere used to argue that Chinese were inferior, dirtier, and that the areas they lived were bad because of this. It was the council of Vancouver who officially labeled the area "Chinatown" in the 1890s and then actually destroyed some of the buildings because of supposed health complaints. The other idea which grew at the same time period was the idea of Chinese immorality. Anderson says the area was seen as "non-Christian, uncivilized, and amoral" and that because of this perception, Chinatown was supposed to be a lawless opium-addicted area with "wickedness unmentionable" (589). At the same time he disagrees that this perception came about purely because Chinese people were not white. He says that instead, the government was motivated by "economic competition" and racial myths which were thoroughly embedded in the government's employees (Anderson 590). 2) In the Aitken reading on school shootings, how is the media depicting these tragic events? And, what is the importance of place i n the varying reactions to the murders? Aitken talks about several school shootings which took place near San Diego in 2001, and compares these to the Columbine shooting that was so shocking when it happened. Several other authors have claimed that the Columbine shooting was inspired by Neo-nazi movements, and that it is disturbing that the media did not report on this information (Aitken 594). Although Aitekn does not think the San Diego shootings were inspired in the same way, he says there is still an element of racism in how the media represented them in news. Specifically this has to do with where the murders took place. Aitken argues that both the place of the school shootings and the way the media reported on them after they happened point towards what he calls "a normalizing and mythic geography of fear" (595). What he means by this seems to be the combination of the old idea everybody has that it can never happen where a person lives because where that person lives, at leas t in America, is always normal, middle-class, and safe. The fear and horror takes place in other parts of the world, or in non-white communities, in places other than the "mythic place of white middle-class America—

Implementation Controls and Executive Summary of Massives Marketing Essay

Implementation Controls and Executive Summary of Massives Marketing Plan - Essay Example Political stability, positive economic growth, technological capability, strategic geographical location and business friendly conditions would be the criteria that will govern what country to choose. Japan, which suffices all the criteria, would be the most likely candidate. An alternative would be India due to its booming Information Technology industry and its strategic geographical location in the Asian region. This move would also help in attaining or even surpass the targeted number of partnerships. The company is currently charging a minimum of $30,000 for its software licenses. The company also charges 20% of the license fee for annual software maintenance and $25,000 for its web auditing services. The decrease would result to $1,500 cut for licensing, 10% cut on maintenance and $2,500 for auditing services (Massive Network, 2006). Reducing prices, all the while assuring product and service quality, provides a competitive edge the company can bank on. Although this translates to losses in revenue in the short run, it provides an attractive choice for future clients and assures continued patronage. This reduction will apply to future as well as present transactions. The acquisition of Massive by Microsoft has provided the means to acquire the necessary funds to conduct research and development to widen product and services range ( Wash, Microsoft Acquire Massive

Professional Responisbility Ethics Research Paper

Professional Responisbility Ethics - Research Paper Example And the Attorney, after reading the draft prepared by the Legal Assistant, decides whether the firm would handle the case, and then the attorney decides the settlement range, strategies, and ultimately finalizes the settlement. The information regarding case strategies are conveyed to the client by the Legal assistant. In addition, the legal assistant interviews witnesses, and negotiate settlement number with the insurance company. According to Canon 3 EC 3-2 of the ABA Model Code of Professional Responsibility, the sensitive variations in the considerations that bear on legal determinations often make it difficult even for a lawyer to exercise appropriate professional judgment, and it is therefore essential that the personal nature of the relationship of client and lawyer be preserved. As a result, the American Bar points out that a competent professional judgment requires trained familiarity with law and legal processes, and an analytical approach to legal problems. Admittedly, Att orney can claim that the Legal Assistant was a law student and had considerable amount of experience in handling such cases. However, the American Bar Association reminds that a non-lawyer, despite some experience, is not governed by the same rules in matters of integrity or legal competence as an attorney is. That means, despite the great degree of skills and experience of the Legal Assistant, the legal assistant cannot be entrusted such tasks which are to be done by the Attorney. However, there are disputes regarding as to what constitutes the practice of law. It is, in fact, difficult to explain in concrete terms what constitutes legal practice. However, the mere fact is that people go to a lawyer when they are in need of a professional legal judgment (EC 3-5). If this is the case, it becomes evident that Attorney has blatantly violated the ethical codes as Attorney does not directly interact with the clients. The initial interview is solely handled by Legal Assistant without any supervision of Attorney. Thereafter, it is the Legal Assistant who makes a draft of the complaint for the Attorney to read. Purely based on this report, Attorney decides if she would take up the case. That means, the clients are denied their right to listen to the legal opinion of a lawyer regarding the matter. It is pointed out in EC 3-4 that lay people who seek legal services are not in a position to judge if they will receive proper professional attention. Also, legal matters are very serious matters that involve confidences, reputation, property, freedom, or even life of the client. So, when a person approaches Attorney with such serious legal matters which are highly confidential and demanding, it is highly improper to permit a non-lawyer to handle the issue even without supervision. In addition is the fact that such non-lawyer assistants, despite experience and skills, are not subjected to the regulations of the legal profession. Admittedly, EC 3-6 provides an even clearer vi ew of the situation. According to the guideline, if a lawyer wants to delegate a task to a clerk, secretary, or any other lay person, the lawyer must ensure direct relationship with his client. Now, going back to the case study, it becomes evident that Attorney does not keep any relationship with his clients at all. The attorney does not allow direct interaction or consultation, and lets the Legal Assistant conduct the initial intervie

The decision in IATA v Ansett Australia Holdings (2008) 82 ALJR 419; [2008] HCA 3 allows contracting parties to ignore the effect of the pari passu rule to the detriment of general creditors. Discuss and examine the reasoning in the case. One of the principle aims of insolvency law is to provide an equal, fair and orderly procedure in handling the affairs of insolvents ensuring that creditors receive an equal and equitable distribution of the assets of the debtor. This is the pari passu (equal sharing) principle, which is generally regarded as being the foremost principle of insolvency law. The rule operates to ensure that creditors of the same priority receive an equal percentage return from the insolvents company’s assets. However, there are often many exceptions to the principle that overcome it such that there are often few assets to be shared, equally or not. Although not in the nature of a secured creditor, a creditor may enter into an arrangement with a debtor company that subsequently goes into liquidation that serves to give that creditor priority rights outside the liquidation. This can apply in clearing house arrangements in certain industries where payments between members of the clearing house are dealt with by mutual set off; in insolvency terms such an arrangement serves to negative the debtor/creditor relationship in respect of the obligations to which the arrangements apply. ‘Ansett collapsed on 12 September 2001 and administrators were appointed. It was then a member of the IATA Clearing House, which pays out airlines for services provided to other airlines in accordance with agreements between IATA and the airlines, including Ansett. International airlines regularly carry passengers and goods on behalf of other airlines. The Clearing House avoids the necessity for the airlines to make and receive numerous payments for such operations. Each month, airlines with a net credit balance receive a payment from the Clearing House while those with a net debit balance are obliged to pay funds into the Clearing House. The agreements between IATA and the airlines provided that settlement of amounts payable would be in accordance with IATA’s Regulations. IATA claimed to be a creditor of Ansett and alleged that Ansett had a net debit balance of $US4,370,989 outstanding as at December 2001.’ The high court in International Air Transport Association v Ansett Australia Holdings Ltd (2008) 82 ALJR 419 rejected an argument that this was contrary to public policy as being against the pari passu principle, as found by the House of Lords in British Eagle International Airlines v Compagnie Nationale Air France [1975] 2 All ER 390; [1975] 1 WLR 758. The house of Lords had decided that the IATA clearing house arrangements were against public policy because they sought to exclude certain property of the insolvent company from the pool available for the distribution to creditors and thereby infringed the pari passu rule. In the particular circumstances in Ansett, which was under a Deed of Company Arrangement, the administrators unsuccessfully claimed credits due to Ansett (but not processed through the clearing house) as at the commencement of the administration, contending hat the deed prevailed over the clearing house agreement. The High Court found that the IATA agreement and regulations applied and Ansett’s rights were not to debts owed to it by other members of the clearing house scheme, but rather the contractual right to receive payment from the IATA if, on clearance, a credit was due to it. Overall, the pari passu principle operates strictly, but it also operates within very confined limits. Apart from the explicit statutory exceptions that have been made, equal treatment of claims applies only among the general body of unsecured creditors. Secured creditors, and others such as those who have retained title to goods supplied to the debtor, are a separate group and are generally entitled to withdraw ‘their’ property that is left, that is, the unsecured property. 3. The automatic discharge available to most bankrupts under the current legislation is too lenient and encourages reckless business behaviour. Discuss. A person is automatically discharged from bankruptcy three years after filing their statement of affairs, unless there is an objection by the trustee. Also, a bankruptcy person can continue or start proceedings concerning their employment, such as unfair dismissal or harassment in the workplace. Any other legal proceeding commenced before bankruptcy are automatically stopped, but if the trustee believes that the proceedings have merit, and creditors are willing to fund the action and indemnify the trustee for costs then the trustee can continue them. Trustees must act reasonably, and they have a duty to consider whether the proceedings have merit and should be continued. After discharge from bankruptcy, the bankrupt is released form most of their outstanding debts, called provisional debts. On discharge, the bankrupt is relieved of any debt created by a provisional order and/or a final determination by the Victims Compensation Tribunal made before the date of bankruptcy. Many amendments have been made to the Bankruptcy Act 1966 in recent years to better balance the interests of debtor and creditor, to overcome the view that bankruptcy is â€Å"too easy† and to prevent debtors form using bankruptcy to evade their responsibilities. Although the current legislation is thus quite lenient towards bankrupts, the consequent disadvantages of bankruptcy for the debtor suggest the current legislation is not an encouragement for reckless business behaviour. These consequences include; losing virtually all property (car and household property is protected), losing the ability to obtain credit or enter other commercial transactions without disclosing that they are bankrupt, carry on a business under an assumed name or firm name without disclosing their true name and that they are bankrupt, and any partnership of which the bankrupt is a member of is automatically dissolved by the bankruptcy, unless otherwise provided by the partnership agreement. Not only that but the bankrupt also cannot be a director of a company or a member of a local authority, a member of the House of Representatives or of the Senate . Overall, being bankrupt is public; a record of the bankruptcy goes on the National Personal Insolvency Index (an electronic public register), so bankruptcy can be searched by the public and may be advertised by the trustee, thus certainly affecting the bankrupt’s credit rating. Bankruptcy is normally a last resort. It had both advantages and quite serious disadvantages. There are also some debts from which the bankrupt person is not released from including: †¢Child support debts: The creditor can continue recovery action for child maintenance debts incurred before and during bankruptcy. The bankrupt is only released form liability for interest owing on such debts at the date of bankruptcy. †¢Bail bonds and court fines: The person is not released form debts arising form bail bonds and court fines. †¢Proceeds of crime: The person remains liable for pecuniary penalty orders under the federal Proceeds of Crime Act 1987. †¢Debts incurred through fraud: The person is not released from debts incurred through fraud or a breach of trust, including money owed to Centrelink or the ATO obtained through fraud or misrepresentation. †¢Unliquidated claims: The person is not released from debts arising from unliquidated claims which, although arising from something that happened before the bankruptcy, are not resolved at the date of bankruptcy. †¢Debts incurred since entering bankruptcy: The person is liable for any debts incurred since the date of bankruptcy. It is thus evident that whilst the automatic discharge after three years is quite lenient, it does not encourage reckless business behaviour as the consequences and disadvantages of entering bankruptcy often do not outweigh the advantages. 5. The question of what constitutes an uncommercial transaction is, in the light of authority, difficult to state precisely. Discuss the recent authority and the concept of uncommercial transaction. An ‘uncommercial transaction’ is defined broadly as a transaction that a reasonable person in the company’s circumstances would not have entered into in regard to: a)The benefits to the company of entering into the transaction b)The detriment to the company of entering into the transaction c)The respective benefits to other parties to the transaction of entering into it d)Any other relevant matter ‘Transaction’ is not defined but examples include a transfer, charge, guarantee, payment, obligation incurred, a release or waiver and a loan. Section 9 also provides that a transaction must be one ‘of the company’. That is, one to which the company is a party. This requirement has given rise to some difficulties in the context of unfair preferences. An uncommercial transaction is ‘a bargain of such magnitude that is could not be explained by normal commercial practice’. Section 588FB (2) makes it clear that the transaction does not need to involve a creditor of the company as a party nor does it prevent the transaction being uncommercial if it is a transaction that is given effect to, or is required to be given effect to, because of an order of Australian court or a direction by an agency. Section 588FB needs s 588FC, that is, an uncommercial transaction will not be voidable unless it is an insolvent transaction. Section 588FC provides: ‘A transaction of a company is an insolvent transaction of the company if, and only if, it is†¦ an uncommercial transaction of the company’ and: a)Any of the following happens at a time when the company is insolvent: (i)The transaction is entered into; or (ii)An act is done or an omission is made, for the purpose of giving effect to the transaction b)The company becomes insolvent because of, or because of matters including: (i)Entering into the transaction; or (ii)A person doing an act, or making an omission, for the purpose of giving effect to the transaction During the case of Ziade Investments Pty Ltd v Welcome Homes Real Estate Pty Ltd [2006] NSWSC 457 the question ask to the court was whether certain transactions involving grants of mortgages over the company benefited person due to their ‘uncommercial’ nature while the company was insolvent. The court help that the mortgages were uncommercial transactions under s 588FB(1) and that they were also insolvent transactions under s 588FC. In the case there was no evidence that the mortgages secured future advances; only previously unsecured debt. They were not granted in consideration of forbearance to sue by the creditors. The mortgages did attempt to grant security for partially statute-barred debts and this helped to show that the transactions were uncommercial. Under s 588FE(3), a liquidator will expect to have disgorged any uncommercial transaction, which qualifies as an insolvent transaction, if it was entered into, or an act was done for the purpose of giving effect to it, during the two years ending on the relation-back day. A time period of four years ending on the relation-back day applies to uncommercial transactions, which qualify as insolvent transactions involving related entities of the company. The time is even greater where the uncommercial transaction as an insolvent transaction was entered into for the purpose of defeating, delaying, or interfering with, the rights of any or all of its creditors in a winding up. In such circumstances the transaction is voidable under s 588FE(5) if it was entered into, or an act was done for the purpose of giving effect to the transaction during the 10-year ending on the relation-back day. 8. Discuss in 750 words any particular aspect of insolvency, which has interested you and say why it is of practical importance. – Effects of bankruptcy on property. The effects of bankruptcy on property is particularly of practical importance as it is a substantially key concept in the area if insolvency. It covers essential aspects including divisible property, property a bankrupt can keep, the bankrupt’s home, money and goods received and property previously disposed of. Beginning with divisible property, a trustee can take certain of a bankrupt’s property, in Australia or elsewhere (subject to the law of the country where the property is). Property the trustee can take to pay creditors include: †¢The bankrupt’s interest in a house †¢Cash in the bank †¢Jewellry †¢Stocks, shares and debentures †¢Fixtures and fittings †¢Gifts and legacies under a will †¢Crops The trustee’s decision about what to do with the assets available for sale and distribution among creditors will depend on what they are. If the assets have little value, the trustee may ask the bankrupt to find a buyer rather than incur the expense that might be involved if the trustee had to find one. The trustee may even be prepared to accept less than market value where costs will be saved by not seizing and selling the goods. Secondly, the property a bankrupt can keep is listed in the Bankruptcy Act . These include: †¢Ordinary clothing †¢Necessary household goods †¢Tools or trade if they are to be used to earn income, up to the value of $3500 †¢Most policies of life insurance, endowment assurance, endowment or annuities †¢Amounts paid to the bankrupt under certain rural assistance agreements between the Commonwealth and the states. A bankrupt can keep a vehicle used for personal transport in which they have a net equity or up to $7050 to the bankrupt form the proceeds so they can buy another. The trustee may not take money received as damages or compensation for personal injury or death to the bankrupt of their family, defamation payments, or any property bought with or mostly with, that money. Thirdly, if a bankrupt owns, or is purchasing a home, the trustee normally sells the home if there will be a surplus after paying the mortgage and sale costs. If the home is owned jointly by the bankrupt and someone who is not bankrupt, the trustee either: †¢Becomes registered as a tenant-in-common of the home with the non-bankrupt person or, †¢Lodges a caveat on the title to protect the bankrupt’s interest. Non-bankrupt joint owners have first option to buy the bankrupt’s interest in the home form the trustee. If they cannot afford to do so they may agree with the trustee to sell the home, and receive an equal share of any money left over after the mortgage and costs are paid. Fourthly, at any time during the bankruptcy the trustee may take any money (excluding accumulated income) or other items the bankrupt receives, such as gifts, lottery winnings or money received under a will. If the bankrupt does save up and buys items that are nit protected during bankruptcy, these may also be taken by the trustee in certain circumstances. However a bankrupt’s accumulated income held in a bank account is protected. Finally, some debtors, seeing the threat of bankruptcy, try to put their property beyond the reach of creditors by transferring it to others, often family members. Property can be reclaimed by the trustee if it was: †¢Given away or sold in the five years before bankruptcy for less than its full value, or †¢Given away or sold at any previous time with the intention of defeating creditors. Transfers or property under a maintenance agreement before the bankruptcy are not affected unless fraud can be established. This it is evident that the effects of bankruptcy on property are a vital area of insolvency and one of practical importance. Bibliography Australian Bankruptcy Act 1966: with Regulations and Rules.

North Atlantic Treaty Organization Expansion Politics Essay

North Atlantic Treaty Organization Expansion Politics Essay This paper will examine North Atlantic Treaty Organization (NATO) Expansionlooking at the real benefit of NATO growing. Does it provide leverage that shapes the political and economic development of European countries where democracy and free markets are not yet taken for granted or still growing? As discussed in our regional studies elective on Europe NS 2206, in order to win a NATO membership, the candidate countries must agreed to long agendas of reforms, ranging from ensuring free press and fair elections to protecting minorities and acting against drug trafficking and corruption. Currently NATO is comprised of twenty-eight members, with additional candidates awaiting approval (i.e. Bosnia and Herzegovina, Macedonia, and Montenegro). NATO had twelve founding member nation they were the United States, the United Kingdom, Canada, Belgium, France, Iceland, Italy, Denmark, the Netherlands, Luxembourg, Portugal, and Norway. Although membership in to NATO is rather difficult to achieve, NATO has added new members through six expansions since its founding in 1949. Throughout NATOs history it has established different programs with the intent to create greater regional cooperation between NATO and its neighbors. These programs include the Partnership for Peace, the Mediterranean Dialogue initiative, and the Euro-Atlantic Partnership Council. From these programs NATO has established relationships that have led to new NATO members. With the collapse of communism and the disintegration of the Soviet Union, NATO has experienced something of an identity crisis. NATO was originally conceived as a military alliance to deter Soviet expansion into Western Europe, the fall of the Berlin Wall and collapse of the Soviet Union forced NATO to reassess its once clear objective. A former Supreme Allied Commander Europe General Joseph Ralston once said that, For most of NATOs history the strategic problem was easily defined: we could predict where we might fight and under what conditions.But today we have a much different problem. We do not know who the enemy might be, and we do not know where we will fight.  [i]  As the political and military circumstances changed in Europe, many member nations believed that NATO should adapt and reflect these changes. In 1995, the NATO Alliance published the results of a Study on NATO Enlargement that considered the merits of admitting new members and how they should be brought in.  [ii]  It concluded that the end of the Cold War provided a unique opportunity to build improved security in the entire Euro-Atlantic area and that NATO enlargement would contribute to enhanced stability and security for all.  [iii]  The Study further concluded that enlargement would contribute to enhanced stability and security for all countries in the Euro-Atlantic area by encouraging and supporting democratic reforms, including the establishment of civilian and democratic control over military forces; fostering patterns and habits of cooperation, consultation, and consensus-building characteristic of relations among members of the Alliance; and promoting good-neighborly relations.  [iv]  The Study also concluded that enlargement would strengthen the Alliances ability to contribute to European and internat ional security, strengthen, and broaden the transatlantic partnership.  [v]   In 1997, the United States Clinton Administration led efforts to invite three former Eastern bloc communist countries, Hungary, the Czech Republic, and Poland to join NATO. Since their invitation in 1997, there have been a number of further invitations for membership to newly democratized states seeking membership into one of the greatest military alliances in the world. After this fourth enlargement in 1999, the desire to become a member of NATO spread rapidly both into the Baltic and seven East European countries and they lobbied for NATO membership. Seven of these countries joined in the fifth enlargement in 2004. Albania and Croatia joined in the sixth enlargement in 2009. This pushed NATOs boundaries further east than they had ever imagined. In November 2010, NATO members adopted a new Strategic Concept at the Lisbon Summit. They reaffirmed the Alliances commitment to keep NATOs door open to any European country in a position to undertake the commitments and obligations of membership, and contribute to security in the Euro-Atlantic area.  [vi]   This NATO expansion is accomplished by each new potential member nation through a Membership Action Plan (MAP) mechanism. This is a procedure where the current members review new members formal applications. The mechanism was approved in the 1999 Washington summit. A nations participation in MAP entails the annual presentation of reports concerning its progress on five different measures: (1) willingness to settle international, ethnic or external territorial disputes by peaceful means, commitment to the rule of law and human rights, and democratic control of armed forces; (2) ability to contribute to the organizations defense and missions; (3) devotion of sufficient resources to armed forces to be able to meet the commitments of membership; (4) security of sensitive information, and safeguards ensuring it; and (5) compatibility of domestic legislation with NATO cooperation.  [vii]   The question of NATO enlargement has not been made without it debate by its member nations. They have debated the arguments for and against expansion. An expanded NATO, they argue, may provide the military security and political integration necessary to aid the development of these young democracies.  [viii]  Furthermore, these experts contend that enlargement will help secure a more stable and peaceful future for Europe, which is crucial for U.S. interests.  [ix]  Critics of expansion contend that enlarging NATO risks diluting both its military effectiveness and capabilities. They argue that the new alliance will lack the cohesion and clearly defined purpose that made NATO in its previous incarnation the most successful military alliance of modern times.  [x]  Opponents of expansion also insist that the economic price of enlargement far outweighs its benefits. Furthermore, these experts fear that an enlarged NATO threatens to divide the world into coalitions, not to ment ion the very real possibility of isolating Russia and fanning the flames of the hard-line forces that still threaten Russias democratic development.  [xi]   The six large expansions have made NATO change policies and organizational structure in order to accommodate the newly added states. Some members nations as well as members of the United States Congress have asked what will further expansion cost; who will pay for the costs; is it necessary; how should enlargement be conducted; what is an expanded NATOs purpose? Mr. Sarwar A. Kashmeri tries to answer these questions in his new book NATO 2.0: Reboot or Delete? He provides some insights stating, America has underwritten the security of Europe for over sixty years. It is not a state of affairs that I believe the increasingly pressured American taxpayer will look upon favorably any more. Especially considering that the European Unions gross domestic product now exceeds Americas and the combined defense budget of the Member States of the European Union of around à ¢Ã¢â‚¬Å¡Ã‚ ¬200 billion (over $300 billion) is not appreciably smaller than Americas defense budget after removing the expe nses of the Iraq and Afghanistan wars and subtracting the expenses of Americas world-wide responsibilities, a global role that Europeans seem to have no desire to underwrite or assume.  [xii]   These costs are in effect a return on NATOs investment in these new member countries. The NATO alliances enlargement has promoted stability in Europe by providing a secure environment for new members for further consolidation of democracy and open markets. The progress made in a few years by the latest members to NATO such as Albania and Croatia have been impressive and deserves reward. These countries spent more than eight years in rigorous preparation for NATO membership. Today, Croatia has the most impressive economic performance, and real estate prices, of any country in southern Europe.  [xiii]  In recent years, Albania has contributed more soldiers to missions in Iraq, Afghanistan and international peacekeeping than most NATO allies.  [xiv]  These new members have made the trans-Atlantic alliance stronger. Philip H. Gordon, Senior Fellow for U.S. Foreign Policy at Brooking Institute, said it best in his statement to the Senate Foreign Relations Committee on March 11, 2008 when he stated, that NATO enlargement has contributed to security and prosperity in Europe. The incentive of NATO membership has led aspiring countries to reform their political systems, liberalize their economies, root out corruption, resolve territorial disputes with neighbors, rationalize their military establishments, and improve minority rights. Once in the alliance new members have contributed troops for vital NATO missions in the Balkans and in Afghanistan and many sent forces to join the U.S.-led coalition in Iraq. In turn, NATO membership has reassured their populations of political and military solidarity with the United States and members of the European Union, enabling them to focus on improving the well-being of their citizens rather than worrying about the types of military threats they had lived with fo r centuries.  [xv]  

Nanobots The New Nemesis Of Cancer Biology Essay

Nanobots The New Nemesis Of Cancer Biology Essay The term nanotechnology will be one which would be widely used in the near future. It is in the leading position in comparison to futuristic nanotechnologies e.g., surgical nanomachines in terms of extensive research, application and products in pipeline. Nanotechnology is popularly known as the science of small or scientifically can be described as the technology to develop materials and structures of the size range from 1 to 100 nanometres. It will have tremendous applications in the field of medicine especially for cancer treatment Oncologists, physicians who study, diagnose, and treat cancerous tumours, of every nook and corner of the world has been relentlessly researching for methods for the early detection of cancer and precious localization of cancer therapeutics with minimal adverse effects to healthy tissues. Research in nanotechnology has shown promising possibilities for achieving this goal Chemotherapy is one of the most common cancer treatments used. It is a process that makes use of cytotoxic chemicals to exterminate cancerous cells. The chemicals may either be injected or taken orally. Chemotherapy may also be administered by rubbing it on the patients body. But chemotherapy actually is a harsh form of cancer treatment that kills not only the target malignant cancerous cells, but also many good non-target tissues as well. In some cases it has been guessed that chemotherapy does more harm than good. The patients even if they recover from the cancer disease and avoid death through chemotherapy, they still will be affected by the harsh side effects of it. Some of those side effects may be more harmful and painful than the cancer they had before. But equally effective remedies have not yet been found. Nanobots are expected to change that. It will provide better ways which makes the treatment safer. By joining multidisciplinary engineering inventions in nanotechnology, an opportunity for development of enhanced, miniaturized and low cost diagnostic/imaging instruments and treatment machines has opened. The future possibility of tackling pain- the bitter side of cancer therapy, through nanotechnology would be considered one of the biggest breakthroughs. How are nanobots made and what are they made off Development of nanobots is a rather complicated process. Scientists have made significant progress in this field, but have not deployed a nanobot which is entirely mechanical. Most of the developed nanobots at present are partly or mostly biological in nature. Nanobots are adapted machine version of bacteria. They are designed in such manner so that they can function on the same way as that of both bacteria and common viruses in order to interact with and repel them from the human system. The best way to create a nanobot is to use another nanobot. But the problem lies in getting started. An ideal material for the construction of nanobots has not yet been found. But expert scientists believe that silicon may be that ideal material, because of its traditional use for delicate electronic devices. Microscopic silicon components called transducers have so far been successfully built into nanobot legs. Selection of an ideal fuel for its working is also a problem faced by the scientists since most of the commonly used fuel units like solar cell or batteries cannot be shrunk to nanoscale. However, nuclear technology may provide answer for this. Researchers consider of equipping a thin sheet of radioactive material as fuel. As the radioactive atoms decay and release energy the nanobot would be able to utilise this power source. Another nice side effect of this system is its ability to renew automatically. With the constant circulating nuclear energy it would supply, this fuel cell would never need to be replaced. Another method to power up the nanobot is using the patients ow n body. Nanobots acquire power directly from the bloodstream. A nanobot attached with electrodes can form a battery using the electrolytes found in the blood or the nanobot could contain some chemicals that would perform some chemical reactions with blood to produce energy. Structure and working of nanobots Nanobots are very small that they can easily enter the body and flow along the bloodstream. The exterior of the nanobots are constructed similar to the carbon atom structure in a diamond due to its inert properties and strength. It has super-smooth surfaces which lessens the triggering of the bodys immune system, allowing its movement inside the body unaffected. The glucose or sugars present inside the body may cause hindrance for its motion, and hence, the nanobots will have other biochemical or molecular parts depending on its tasks. There are few items that might be found in a nanobots toolkit. Those are Medicine cavity It is a hollow section inside the nanobot that preserves small doses of chemicals or medicine and could release the medication directly to the site of infection or injury. Nanobots can also store the chemicals used in chemotherapy to treat cancer and can carry it directly to the site. Although the amount of medication is comparatively very low, nanobots can apply it directly to the cancerous tissues more effectively than traditional chemotherapy, which depends on the bodys circulatory system to carry the chemicals throughout the patients body killing the cancerous cells and the same time affecting the other healthy cells of the body harmfully. Probes, knives and chisels It is used to remove blockages and plaque. Nanobot need some device to grab, break down and remove these abnormalities. They may also need some devices to crush clots into very small pieces. If a partial clot gets released and enters the bloodstream, it can cause more problems further down the circulatory system. Microwave emitters and ultrasonic signal generators It is used to destroy cancerous cells. The doctors depend on methods that will kill a cell without bursting it. A busted cancerous cell may release chemicals that could cause the cancer to spread further to other portions of the body. Nanobots can break the chemical bonds in the cancerous cell and kill it without breaking the cell wall using fine-tuned microwaves or ultrasonic signals. At the same time, the robot could emit microwaves or ultrasonic signals in order to heat the cancerous cells and destroy it. Electrodes Two electrodes extended from the nanobots generate electric current and heat the cell until it dies, thereby killing cancerous cells. Lasers By vaporising tissues, small and powerful lasers could remove harmful materials like plaque in arteries, cancerous cells or blood clots. Scientists are working hard to find a suitable design for the body of the nanobot. It must be fast, aerodynamic and smooth to flow freely along the body and to complete its function. Some believe that a spider-like body would work best, but many nanobot researchers also think that a smaller version of the centipede might be best. They hope that by equipping the nanobot with several sets of fast-moving legs and keeping its body low to the ground, they can create a quick, efficient machine that would also be suitably shaped for introduction into human blood vessels to perform its functions. Nanobots will possess at least the fundamental two-way communication, respond to audio signals and will be able to receive power or re-programming instructions from an external source via sound waves. A network of special stationary nanobots will be positioned throughout the body. These nanobots logs into each active nanobots as it passes and will report results, allowing the interface to keep track of all the nanobots present in the body. Using this, a doctor can not only monitor the patients progress but also can change the instructions for the nanobots to enter into another stage of the healing. When the tasks are completed, it can be flushed out from the body. Nanobots can be programmed to perform different jobs around the body, and one of them will be to locate and destroy cancerous cells. There will be different nanobots to do different jobs to help kill the cancer, for example, one will inject toxins, while the other cuts out the tumour carefully without damaging healthy cells around it. Another robot will be able to send video footage of this happening to the surgeon treating the patient. Advantages of the technology The different advantages of the usage of nanobots are A better method for cancer detection The most commonly used cancer detection techniques like optical identification of malignant changes, cell growth analysis, specific-ligand receptor labelling or genetic test are inaccurate, lengthy and complicated process, which is impractical for clinical use. The detection of cancerous cells using nanobots will be simpler and precise than the traditional methods. Nanobots covered with organic-based fluorescent dyes will be bound to the cancerous cells which makes optical detection easier. A better method for cancer treatment The popular treatments of cancer at present, like chemotherapy, have many harsh side effects even though it helps in the treatment of cancer. It kills healthy cells present in the body along with the cancerous cells and may cause some side effects or even a more painful disease than cancer in the future. They will not be able to live a normal life even after recovering from it. Nanobots on the other hand, carry the drugs or tools used to destroy cancer tissues directly to it. It will disperse the drugs directly to the cancerous cells which leave the healthy cells unaffected thus preventing further side effects to a great extent. Some achievements in nanobotics Researchers at the École Polytechnique de Montrà ©al, in Canada have created a microscopic device that could offer a new and very effective treatment for cancer. The research team has coupled live bacteria to microscopic polymer beads which can carry cancer-killings drugs to create nanobots. The bacterias small size and flagella helps them to fit in and flow through the smallest blood vessels in the human body. A research team of a Californian institute-Pasadena, injected nanobots into a patients bloodstream. It was able to enter into the cancer tumour, deliver double-stranded small interfering RNAs (siRNAs), and turn off cancer genes. Reasons that slow down the use of nanobots at present Scientists do face challenges and are concerned of making nanobot tools effective and safe. For instance, creating a very small laser powerful enough to destroy cancerous cells is a great challenge, but its more difficult to design it so that the nanobot doesnt harm the healthy tissues surrounding the cancerous cells. Even though many scientific teams have developed nanobots that are small enough to enter into the bloodstream, its only the tip of the iceberg. They have to do more experiments and researches to make nanobots a real medical application. Another problem is with the quantity of toxin which goes into each capsule. This is because too much of the toxin at any one point can damage the body, therefore the process has to be spread out over a longer period of time, using lots of small doses. Nanobot consist of a transporting mechanism, an internal processor and a fuel unit. Creating a fuel unit at nano-scale is very difficult with current technology. Another problem in constructing nanobot is selection of material out of which it is made of and breaking it down small enough. The properties or behaviour of metals at large-scale and nano-scale might be different. Another factor that slows down its entry to the medical field is the high cost for the research, development and experiments. Some other applications of nanobots in the field of medicine Applications of nanobots in the field of medicine are practically unlimited. Some of the applications are Treating arteriosclerosis: Arteriosclerosis refers to an abnormality where plaque builds up along the walls of arteries, thereby hindering the normal flow of blood through it. Nanorobots can treat this condition by physically chipping away the plaque along artery walls which would then enter the bloodstream and gets removed from the body. Breaking up blood clots: Nanorobots could travel to blood clots which can cause complications ranging from muscle death to a stroke and break it up. This application can be one of the most dangerous uses of nanorobots, if the robot could not remove the blockage without losing even small pieces into the bloodstream. Small pieces, if entered into the bloodstream could then travel elsewhere into the body and cause more severe problems. The size of the robot also must be small enough so that it doesnt block the flow of blood itself through the arteries. Fighting cancer: Doctors are hopeful to use nanorobots either to attack tumours directly using lasers, microwaves or ultrasonic signals or as a part of a chemotherapy treatment, wherein medication can be delivered directly to the cancer site to treat the patient. According to doctors by delivering small but precise doses of medication to the patient, the side effects of the medicine will be minimized without a bit of loss in the effectiveness of the same. AIDS treatment: It can act as synthetic immune system of the AIDS affected patient which would help him to survive the disease. It could function as replacement helper-T cells in a weakened immune system Helping the body clot: Another particular kind of nanorobots named clottocyte is an artificial platelet, which carries a small mesh that dissolves into a sticky membrane upon contact with blood plasma. Robert A. Freitas, Jr., the scientist who designed the clottocyte, claims that clotting done by clottocyte could be up to 1,000 times faster than the natural clotting mechanism of the body. Doctors can use clottocytes to treat haemophiliacs or patients with serious open wounds also. Parasite Removal: Several nanorobots working together could directly release drugs on bacteria and small parasitic organisms inside a patients body and kill them all. Gout: One of the major functions of the kidney is to remove waste from the breakdown of fats from the bloodstream. The inability of kidney to perform this task develops the condition called Gout which causes waste to crystallize at points near joints like the knees and ankles. A nanorobot, though wouldnt be able to reverse the condition permanently, could break up the crystalline structures at the joints and provide relief from the intense pain at the joints, as a result of gout. Breaking up kidney stones: Kidney stones vary in size and are intensively painful to get removed normally as the size increases. Though doctors can break up comparatively large kidney stones using ultrasonic frequencies to get it removed normally, it is not always effective. A nanorobot could break up these stones using a small laser as well as can carry small ultrasonic signal generators to deliver frequencies directly to the kidney stones. Cleaning wounds: Nanorobots could help to remove dead remains from wounds and thereby decreasing the chances of infection. They can be used very effectively in cases of puncture wounds, where conventional methods of treatment are difficult. Conclusion Nanotechnology has become an emerging tool which helps to find solutions for several questions of different fields. It has provided the hope from preparing cure for many incurable and deadly diseases of the present. But still more researches and improvements are required, before actually applying it. The investments and resources required for the research, development and performance trials for nanobots are considerably large. Hence the sponsoring agencies, both private and government, should provide more investments and resources which make these nanotechnology inventions (like nanobots) more cost-effective and easily available for patients all across the world and of all economic classes. It will open a new horizon in the field of medicine especially for the study and treatment of cancer. Health departments in association with governments should form policies that support the usage of nanomaterials and prevent the use of treatments which are harmful and has harsh side effects, like chemotherapy, for cancer. The future holds lot of promises as nanotechnology has the potential to provide cancer therapy by challenging the problems like high treatment costs and undesirable side-effects.

Strategies to Motivate Students Essay -- Education, Learning Teaching

Strategies to Motivate Students In the field of education there is a broad spectrum of strategies to motivate students. Through research only a sample of the spectrum was covered, which consisted of twenty-nine sources. Four interrelated categories were created that individually provide strategies to motivate students. The four categories consist of teaching strategies to motivate students, program structure to motivate students, self-motivational strategies, and parent strategies to motivate students. All of these categories conclude that a positive environment provided by parents, school officials, and the students themselves, act to enhance a students motivational drive to succeed in the classroom. Teaching Strategies to Motivate Students A teaching strategy is any technique a teacher projects in the classroom. Enthusiasm and body language in combination with creative classroom activities are effective tools for teaching. According to Barbara Davis in "Incorporating Instructional Behaviors That Motivate Students" from the Tools For Teaching web site, most students respond positively to a well structured course taught by an instructor who is enthusiastic and shows interest in their students as well as their subject. With this in mind, Davis gives six instructional behaviors that teachers can utilize to motivate students. These are holding realistic expectations, helping them to set achievable goals, informing students of how to succeed in their class, strengthening self-motivation, avoiding to create competition among students, and being enthusiastic about their subject. Davis argues, beneath the same web site in Motivating Students, that instructors can do the following to encourage st... ...is a collection of opinions on the subject about teachers and school administrators around the United States. It contains strategies to stimulate students at home and how parents can properly motivate their children to succeed as students throughout their education. 101 Ways Parents Can Help Their Children Achieve is a booklet distributed by the Educational World, written by school administrators. This booklet provides many creative family projects designed to stimulate their children to want to achieve academically. Conclusion A common ground can be derived from all four of the perspectives relating to the broad spectrum of strategies to motivate students. By providing a positive atmosphere at home as well as in the school, a student develops the desire to succeed in the classroom, and later, utilizes this motivation to succeed in life.
