Discuss, in detail, how technology has evolved over the past 20 years in regards to criminal profiling and forensic science, and the way it is being used successfully today by law enforcement.

Sample Answer

Technology can be defined as the knowledge and use of techniques, tools, systems, crafts or methods of organization as a means in order to solve a problem or to achieve a desired end. Originally, the word technology derives from Greek word technoligia-techne meaning art, skill or craft and logia which means study of. The t impact of technology is its significant effect on how humans carry out their duties and has also affect every single facet of human existence, starting from health to agriculture and to transport. The following subsequent paragraphs of this paper are dedicated to discuss into detail the idea of technology.

This piece of the paper endeavors to give a concise synopsis of David Ricardo's idea of comperative preferred position and Samuelson and Jones' Specific Factor model, just as demonstrating an examination between the two, close by with their benefits and inadequacies.

In 1776, Adam Smith in his An Inquiry into the Nature and Causes of the Wealth of Nations showed how exchange increment the welfare of countries who are occupied with exchanging with each other (Smith, 1776). While Smith's work picked up ubiquity, critisised merchantilism and advanced organized commerce, practically speaking numerous countries were as yet connected with arrangements that forced dfferent levies on fares and imports the same.

While Smith's discoveries depended on the idea of outright bit of leeway, in 1817, David Ricardo thought of a model that gave proof how exchange between two gatherings could profit both, even without supreme preferred position. Interestingly with Smith, Ricardo centers around the comperative preferences of the nations. The rule of comperative preferred position alludes to marvels when for example a nation produces two merchandise, and it can deliver one of the merchandise at a lower relative open door cost than the than another nation that is additionally occupied with the generation of a similar two products. As indicated by Ricardo, when both nation got had some expertise in the creation of an item they have comperative preferred position, exchanging those products on an expected a relative value that is found somewhere close to the two nations' relative open door costs, would in the long run outcome higher utility in both nation (Krugman et al, 2011). In Ricardo's old style model, he exaxmined the fabric and wine generation of England and Portugal. The standard ricardian model accepted immaculate challenge, and contained just a couple of factors, for example, work, cost of creation, and the quantity of products can be delivered from their mixes.

For the two nations there is a Possibility Frontier (in no time, PPF), a straight capacity, which shows every one of the blends of good 1 and great 2, that a nation could create given their work blessing and cost of generation. On the off chance that Home nation has comperative bit of leeway in delivering great 1, and Foreign has CA in good2, which means c1/c2 < c1 c2csillag, at that point exchanging can be executed at c1/c2 < P1P2< c1 c2csillag (Krugman et al, 2011)

The model suggests that the two nations profit by the specialization and the organized commerce. Furthemore, it likewise shows that levy forced on fare and import would expand the cost of import products, in this manner the exchange would be ruined.

While Ricardo upheld the cancelation of the 1815 Corn Laws, in the nineteenth century once they revoked it, the approaching imported grain radically scaled down the english market cost for grain, and the english landowners were not able stay aware of the competetion, eventually drove them to liquidation. Conversely, the nullification of the Corn Laws profited the industrial facility proprietors, since the lessen grain costs enabled them to diminish the representatives' wages.

As per Ricardo, unhindered commerce ought to have profited the entire nation, by the by the authentic proof propose generally. This disappointment of Ricardo's model can be clarified with it's effortlessness, as the work was thought to be the sole factor of generation.

So as to eliminat the deficiencies of the ricardian model, Paul Samuelson and Ronald Jones (1974) further built up the idea and joined extra factors of generation. This adaptation of the ricardian model, regularly called Specific Factor model or 2 great 3 factor model, fuses extra factors of creation, for example, capital or land, and these elements are thought to be industry specific.The model is commonly used to show how work dispersion ,factor returns and yield level changes as an outcome of specific changes in the economy, for example, exchange progression, or forcing levies.

At the point when a factor is called explicit it suggests that it is fixed between areas. So as to epitomize it, suppose we have two businesses, one of them produces cowhide sacks and the other one produces strawberries. The machines being utilized in calfskin pack generation are explicit as they can't be allotted to the strawberry business. On the otherhand the strawberry handle, the daylight or the horticultural gadgets can't be moved to the calfskin pack industry either. The model anyway expect that work is versatile between the parts, much the same as in the ricardian model. Furthermore, this model additionally accept impeccable challenge and wages and costs are given. The PPF here is spoken to differetly, it is curved. The model accept that the businesses are planning to boost their benefit, in this way they procure work until the estimation of the last extra work's minimal profitability gets equivalent to the compensation to be paid. Explicit factor model can be seen in the accompanying model. In the event that a nation movements to unhindered commerce, that may prompt the ascent of an item eg. strawberries. Consequently this segment turns into an exporter. At the outset since compensation are clingy in the short run, the ongoing increment in cost will incite the business to contract extra work for the strawberry fields. So as to draw in more work, the strawberry maker must offer a higher pay. Contracting more work they can create more strawberries. In a similar time, the calfskin sack industry is encountering a decrease in their work power, in this manner they should build the compensation to keep their representatives. In the strawberry business as cost and the work expands, the estimation of the minimal result of capital needs to build, opposite the calfskin sack industry's.

The Specific Factor Model, shows how exchange increment welfare, and it is additionally features how salary is diustributed between various parts. As a general rule be that as it may, the Specific Factor Model isn't the most exact either, the Hecksher-Ohlin Model served to address these blemishes.
