What is The Scientific Method, and How is The Theory...

What is the scientific method ,and how is the theory applied to fingerprint analysis? The complete friction ridge identification process involves using the identification philosophy and scientific methodology in determining whether or not an unknown friction ridge impression(herein, called latent) came from the same source as a known inked print (herein called print)to the exclusion of all others. (1) David Ashbaugh refers to this identification process as, a guide of how friction ridge quantative-qualititive analysis is transformed into an opinion of individuality. It describes the friction ridge formations used during analysis while establishing parameters as to how much knowledge one must have to perform such a task.

Battle of Cowpens in the American Revolution

The Battle of Cowpens was fought Jan. 17, 1781  during the American Revolution and saw American forces win one of their most tactically decisive victories of the conflict. In late 1780, British commander Lieutenant General Lord Charles Cornwallis sought to conquer the Carolinas and destroy Major General Nathanael Greenes small American army in the region. As he retreated north Greene directed Brigadier General Daniel Morgan to a take a force west to raise morale in the region and find supplies. Pursued by the aggressive  Lieutenant Colonel Banastre Tarleton, Morgan made a stand in a pasture area known as the Cowpens. Correctly assessing his opponents reckless nature, Morgans men conducted a double envelopment of the British and effectively destroyed Tarletons command. Background After taking command of the battered American army in the South, Major General Greene divided his forces in December 1780. While Greene led one wing of the army towards supplies at Cheraw, South Carolina, the other, commanded by Brigadier General Morgan, moved to locate additional supplies for the army and stir up support in the backcountry. Aware the Greene had split his forces, Lieutenant General Cornwallis dispatched an 1,100-man force under Lieutenant Colonel Tarleton to destroy Morgans command. A bold leader, Tarleton was notorious for atrocities committed by his men at earlier engagements including the Battle of Waxhaws.   Riding out with a mixed force of cavalry and infantry, Tarleton pursued Morgan into northwestern South Carolina. A veteran of the wars early Canadian campaigns and a hero of the Battle of Saratoga, Morgan was a gifted leader who knew how to obtain the best from his men. Rallying his command in a pastureland known as the Cowpens, Morgan devised a cunning plan to defeat Tarleton. Possessing a varied force of Continentals, militia, and cavalry, Morgan chose Cowpens as it was between the Broad and Pacolet Rivers which cut off his lines of retreat. Armies & Commanders AmericanBrigadier General Daniel Morgan1,000 menBritishLieutenant Colonel Banastre Tarleton1,100 men Morgans Plan While opposite to traditional military thinking, the Morgan knew his militia would fight harder and be less inclined to flee if their lines of retreat were removed. For the battle, Morgan placed his reliable Continental infantry, led by Colonel John Eager Howard, on the slope of a hill. This position was between a ravine and a stream which would prevent Tarleton from moving around his flanks. In front of the Continentals, Morgan formed a line of militia under Colonel Andrew Pickens. Forward of these two lines was a select group of 150 skirmishers. Lieutenant Colonel William Washingtons cavalry (around 110 men) was placed out of sight behind the hill. Morgans plan for the battle called for the skirmishers to engage Tarletons men before falling back. Knowing that the militia was unreliable in combat, he asked that they fire two volleys before retreating behind the hill. Having been engaged by the first two lines, Tarleton would be forced to attack uphill against Howards veteran troops. Once Tarleton was sufficiently weakened, the Americans would switch over to the attack. Tarleton Attacks Breaking camp at 2:00 AM on January 17, Tarleton pressed on to the Cowpens. Spotting Morgans troops, he immediately formed his men for battle despite the fact they had received little food or sleep in the preceding two days. Placing his infantry in the center, with cavalry on the flanks, Tarleton ordered his men forward with a force of dragoons in lead.  Encountering the American skirmishers, the dragoons took casualties and withdrew. Pushing forward his infantry, Tarleton continued  taking losses but was able to force the skirmishers back. Retreating as planned, the skirmishers kept firing as they withdrew. Pressing on, the British engaged Pickens militia who fired their two volleys and promptly fell back around the hill. Believing the Americans were in full retreat, Tarleton ordered his men forward against the Continentals. Morgans Victory Ordering the 71st Highlanders to attack the American right, Tarleton sought to sweep the Americans from the field. Seeing this movement, Howard directed a force of Virginia militia supporting his Continentals to turn to meet the attack. Misunderstanding the order, the militia instead began withdrawing. Driving forward to exploit this, the British broke formation and then were stunned when the militia promptly stopped, turned, and opened fire on them. Unleashing a devastating volley at a range of about thirty yards, the Americans brought Tarletons advance to a halt. Their volley complete, Howards line drew bayonets and charged the British supported by rifle fire from Virginia and Georgia militia. Their advance stopped,the British were stunned when Washingtons cavalry rode round the hill and struck their right flank.While this was occurring, Pickens militia reentered the fray from the left, completing a 360-degree march around the hill. Caught in a classic double envelopment and stunned by their circumstances, nearly half of Tarletons command ceased fighting and fell to the ground. With his right and center collapsing, Tarleton gathered his cavalry reserve, his British Legion, and rode into the fray against the American horsemen. Unable to have any effect, he began withdrawing with what forces he could gather. During this effort, he was personally attacked by Washington. As the two fought, Washingtons orderly saved his life when a British dragoon moved to strike him. Following this incident, Tarleton shot Washingtons horse from under him and fled the field. Aftermath Coupled with the victory at Kings Mountain three months before, the Battle of Cowpens aided in blunting the British initiative in the South and regaining some momentum for the Patriot cause. In addition, Morgans triumph effectively removed a small British army from the field and relieved pressure on Greenes command. In the fighting, Morgans command sustained between 120 to 170 casualties, while Tarleton suffered approximately 300 to 400 dead and wounded, as well as around 600 captured. Though the Battle of Cowpens was relatively small in regard to numbers involved, it played a key role in the conflict as it deprived the British of desperately needed troops and altered Cornwallis future plans. Rather continuing efforts to pacify South Carolina, the British commander instead focused his efforts on pursuing Greene. This resulted in a costly victory at Guilford Court House in March, and his ultimate withdraw to Yorktown where his army was captured that October.

Surrounded by land on the southern coast of Oahu, near Honolulu, in the Hawaiian Islands lies the port of Pearl Harbor. At the time of the attack, Hawaii was not a state. However, the United States claimed it as a territory. The U.S. Navy established a base at Pearl Harbor to house the Pacific Fleet, and to train men for war. In the early 1940’s the base became a supply post for Great Britain in the fight against the Nazi Germany attacks. In 1940, World War II was well under way with Great Britain, France, the USSR, China, Greece and other Allies against the Axis Powers when the Japanese bombed Pearl Harbor.

Inflation always bad for an economy Free Essays

Is inflation always bad for an economy? Inflation is a general Increase in prices and fall In the purchasing value of money measured as percentage; ways of measuring It Include the retail price index and the consumer price Index. One cost of Inflation Is that firms may have to spend money, time and effort moving money around financial Institutions (banks etc. ) so that they can ensure It doesn’t lose Its value, It Incurs shoe leather costs as a result of this. We will write a custom essay sample on Inflation always bad for an economy or any similar topic only for you Order Now However these costs can be offset by advances in technology, less human intervention is needed and costs are lower Another cost is that inflation leads to Geiger prices, these high prices reduce the competitiveness of the countries companies on global markets this reduces exports and leads to a dependency on imports, severely affecting a countries balance of trade. As imports are a leakage from the circular flow of income, it has negative effects on consumers within the country. Reduced exports due to high prices may lead to firms having to close, this may lead to staff being made redundant and Increasing the unemployment rate. However, these negative effects may be mitigated If the firms with which the source entry Is trading with has a higher level of Inflation, In which case, the firms In the country will still remain price competitive with foreign companies. One positive of inflation Is that If you have a low and stable rate of demand-pull inflation It may lead to companies producing more as they expect more consumption of their goods. This may lead to them hiring more staff or purchasing more technology, either increasing employment rates or increasing turnovers of other businesses that make the technology required, all of which increase economic activity and have positive effects. Companies can reduce redundancies by increasing real wages by less than inflation, cutting costs but without making staff unemployed which would have sever negative effects on consumers and the economy. The economic costs of inflation are dependent on a variety of factors, such as the degree of Inflation, for example: higher levels of Inflation always have a worse Impact on an economy than low levels, e. G. Hyperinflation reduces the functionality of money and also as low Inflation reduces the effect of shoe leather costs It Is clearly better than high levels of Inflation. Another determinant of the effects of inflation is whether the inflation was correctly anticipated by consumers and producers and whether inflation in one country is higher than the countries it partakes in trade with because if this is the case, measures can be taken to reduce the negative impacts of inflation. For example pensions could be increased to stay in line with inflation. If these factors are all set in a certain way then the effects of inflation can become positive, however generally this is not the case and inflation negatively affects an economy.

Role of Information System Flows †Free Samples to Students

Question: Discuss about the Role of Information System Flows. Answer: Introduction Information system is a specific type of organized system that is solely utilized for the purpose of communication, storing, managing and collecting information. The several operations of data can be easily with the help of the information system (Bajdor Grabara, 2014). My Health Record is one such information system that is going to start by the Commonwealth Government of Australia. It would be launched for storing the information of patients in all over Australia. This report features a particular vision document of the project of My Health Record. The responsibility of making a vision document is given to the business analyst of the project. This vision document comprises of problem, capabilities and benefits or advantages of the project. The Commonwealth Australian Government is going to launch an information system for each and every citizen of Australia. They have decided to name this information system as My Health Record (Wu et al., 2013). It is an online summary of health information and is extremely safe and secured. The patients of Australia could easily fetch their information from all the previously existing health records and do not have to repeat the entire process over and over. The hospitals or the health experts do not have to depend on the manual information system regarding their patients. The most requirement of My Health Record is that it would be continuing the processes for reforming as well as driving the system efficiencies in health industry (Nazi, 2013). The main problem in hospitals or health care centres is the huge expenses that are incurred in the process. The patients do not have to take admission in the hospitals and they could easily manage as well restrict their data entry. My Health Record has various significant capabilities within it. Due to these capabilities, the citizens of Australia would be enjoying important benefits regarding their health information (Arvidsson, Holmstrm Lyytinen, 2014). They will never tell their health problems over and over and once they will tell it would be stored within the system. The first and the foremost capability of My Health Record is that it will be an extremely safe and secured system. Since, the information is related to health, the security of this system is highly required. The second important capability of the My Health Record is that once the details are being told for the first time, it would be solely stored within the system. The third significant capability of the information system would be that the hospitals and the health experts could easily utilize the information whenever required. The next capability of the information system is that there would not be existing any type of manual data entry (De mir Krajewski, 2013). My Health Record would also do the data filtration. This eventually means that when any particular patient would die or not be needing any type of medical assistant, his data would be removed automatically. This would also be the combination of database and information and communication system. However, this system would not be at all complex and everybody could be utilized by all. My Health Record is the particular type of information system that would be launched by the Commonwealth Australian Government. There are several significant benefits or advantages of this information system (Nazi, 2013). They are given below: Managing Information: The first and the foremost benefit of this information system would be that it helps to manage and control the bulk data or information easily regarding patients of Australia. Inexpensive: Another significant advantage of the My Health Record would be the cost effectiveness. It does not incur huge cost. Easy to Implement: The entire procedure of implementing the My Health Record would be very easier (Laudon Laudon, 2016). Data Centrality: The fourth benefit of this system would be that the access to the data through the information system is centralized and thus data searching is very easy. Automatic Data Handling: The data handling is done automatically and does not require manual assistance. Conclusion Therefore, from the above report it is concluded that, information system is any particular system used for storing and manipulating the data of any particular organization. It is considered as one of the most secured methods of securing data or information. The Commonwealth Government of Australia has decided to launch a secured online information system for all citizens. The most significant benefit of the particular information is that it will be storing all types of health details about the patients. They have decided to name this system as My Health Record. For launching this project, the business analyst is supposed to create a vision document that would contain the problem, capability and benefit of the project. This particular report has given a clear demonstration of a vision document of the My Health Record project. References Arvidsson, V., Holmstrm, J., Lyytinen, K. (2014).
