History of Fingerprinting Essay Example

History of Fingerprinting Essay Forensic science used in criminal justice has recently been revolutionized with new DNA technology, but fingerprinting is still the most valid and effective form of identification used in law enforcement today. Going back in the time of ancient Babylon, fingerprints and ridge patterns were used on clay tablets for business transactions and governmental procedures. By the 14th century, the fact that no two prints were alike was becoming more noticeable, thus the history of the fingerprint began.Noting the ridges, spirals, and loops in fingerprints, Marcello Malpighi, a professor of anatomy at the University of Bologna, made no declaration to the value of personal identification, but began to point out the differences in fingerprint patterns in 1686. Then, in 1823, a professor of anatomy at the University of Breslau, John Evangelist Purkinji, discussed nine fingerprint patterns in a published thesis, but still did not take notice to the individuality of each print. It wasnt until 1856 that Englishman and Chief Magistrate, Sir William Hershel, used fingerprints on native documents.After gathering many prints, Hershel took notice to the fact that all the prints were unique and could prove identity from all those he made transactions with. Dr. Henry Faulds, the British Surgeon-Superintendent of Tsukihi Hospital in Tokyo, Japan, shared his studies with Charles Darwin in 1880, but Darwin, who was rather ill at the time, could be of no service to Faulds studies. Eight years later, Sir Francis Galton, a British anthropologist and Darwins cousin, began to study Faulds articles on fingerprint classification. Galton began to concentrate on linking fingerprints to genetic history and intelligence, but had no luck. Scientifically proving that fingerprints never changed during ones lifetime, Galton stated that the odds of two prints to be exactly the same were 1 in 64 billion. In 1901, Sir Edward Richard Henry revised

â€Å"God bless the child that’s got his own . . . that’s got his own.† â€Å"We could make that a society in which those who chose to produce new people knew what being parents must involve†, (Penelope Leach, bconnex.net/~cspcc/ daycare/wecould.htm). It is my proposal that we, the people who currently inhabit this planet, implement ‘Breeding Licenses’ for the betterment of the human race. Initially this may seem like an extreme and heartless course of action, but it is my objective to convey the importance, benefits, and caring that an execution of a law of this magnitude would entail. In today’s societies we are dealing with excessive violence, abuse, drug abuse, overpopulation and starvation, neglect, depletion of natural resources, general apathy, and world wide and individual dysfunction. It is all due to a cyclical succession of breeding more and more of the same species that has the knowledge of how to fix the problems of the world but not the knowing of where to begin. I suggest we begin at the base-root of the problem. We must start at the beginning. Start with the people.

Any subject in the criminal justce systre Essay

Any subject in the criminal justce systre - Essay Example Investigation usually marks the first step for a criminal case. The police usually perform this. In this regard, when a person is accused of offense, the police are usually required to carry out investigation to gather enough evidence, among them identifying the suspect in order to support an arrest. For instance, when an individual is confronted with robbers, the victim is usually required to report the matter to the law enforcement officers, who will then begin investigation based on the information provided by the victim (Burns, 2006). Search Warrant Usually, when the investigation officers are satisfied that there is probable cause for a crime, the law enforcement officers are required to seek for a search warrant, which permits them to search the premises. A probable cause in this case referred to the standard of proof indicating that there are enough facts on the ground showing that there is enough evidence of a criminal activity in a given place. Judges usually issue the search warrant, when they are satisfied that there is indeed probable cause. This implies that if the law enforcement officers fail to show enough evidence, then the police officer may be denied the right to carry out the search. However, a search warrant may not be needed under emergencies usually referred to as exigent ‘circumstances’ (Neubauer, and Fradella, 2010). During a search, the officers may interrogate witnesses, who might have been at the scene of the alleged crime

Public Economics Essay Example | Topics and Well Written Essays - 1250 words

Public Economics - Essay Example (a) According to Segura and Braun (2004, p.34), â€Å"a club good is a particular case of public good, which has the characteristics of excludability and non-rivalry (or partial non-rivalry, depending on the congestion).† It could never be a pure public good nor pure private good because it has the characteristic of least partly ‘rivalrousness’ and ‘excludability.’ Therefore, the usage of this good is exclusive for the club members (voluntary) and not for the good of the public, because if a good is already consumed by one of the members, the others will lose the opportunity, and the benefits are kept away from non-members (Murshed, 2010, p.153). The non-members are not allowed to assess, join and cooperate in the group because club members’ priority is to gain maximum utility over the certain goods. In other words, club goods are not public goods but they are a ‘quasi-public’ or partial public goods, for they are only made availab le to two or more individuals, and restricted or protected from the outsiders consumption or non-members that did not contribute to the club’s creation (Brummer, 2008). ... See for instance, a single individual will not have the capacity and the resources to build a club on its own, because it will shoulder the cost of the construction as well as the maintenance. Also, even if he did, the enjoyment will be more appreciated if it is shared to two or more people as long as the number of members did not detract the enjoyment of the other group members. A theory of club goods is â€Å"intrinsically bound up with issues of inclusion and exclusion, and hence, how members are selected and non-members excluded. This implies some notion of discrimination† (Crawford, 2006, p.121). â€Å"The important point here is that many government services are closer to the characteristics of club goods (or at least they are impure public goods) compared to pure public goods, particularly at the local level† (Murshed & Tadjoeddin, 2008, p.7). One of these services is higher education or universities which can be seen as a club good particularly the rising of the student tuition fees (Sandler & Tschirhart, 1997, p.336). Education itself is a club good because whose benefits are non-rival and non-excludable, thus it can be shared without detracting the availability of opportunity to other individuals. However, because of the rising student tuition fees poorer students would not be able to obtain the offered benefits of higher education, although it gives access to disadvantage students (Kershaw, 2010). This education that based on financial and not on academic ability is some kind of a restriction in the entry of poor bright students in an elite institutions or this can be considered discrimination. Withdrawal of the public funding would only make

Global HRM (BUS 303) Essay Example | Topics and Well Written Essays - 250 words

Global HRM (BUS 303) - Essay Example This impacts the HR planning in the domain of cultural diversity and cross cultural dimensions because the workforce in today’s world is highly consist of culturally diverse employees (Brewster and Harris). The implications of HRM in the context of Hoftede’s model of cultural dimensions become vast in the domain of humanistic and cultural diversity. The HRM managers are required to have knowledge regarding to every culture which exist in the workforce of organization including individualism and collectivism, power distance, orientation and gender dominance (Brewster and Harris). In Trompenaars’ model, several differences are illuminated in order to create a balance in the workforce which is the responsibility of HRM (Youssef). These differences include universalism and particularism, individualism and collectivism, specific and diffused, and inner directed and outer directed which varies from culture to culture. HRM managers in the international context must acknowledge these differences on certain circumstances in concordance with the culturally diverse workforce (Brewster and Harris). The GLOBE model proposes several cultural aspects which must be understood by international HRM managers and HR planning. These aspects include diversity in humane orientation, assertiveness, avoidance of uncertainty and performance orientation (Brewster and Harris). International HRM is the contemporary issue which mainly deals with the cultural aspects because of the incorporation of cross cultural workforce. Cultural studies and models must be implied by each HRM manager in conformity with the culture of its workforce by which the deliverance of successful HRM can be

The hydrogen bomb

The hydrogen bomb INTRODUCTION The Hydrogen bomb was first suggested by Edward Teller in 1942 but active work on it was pursued in the summer of 1942 by Oppenheimer,Teller,Los Alamos and others. The first thermonuclear bomb was exploded in 1952 atEnewetak by the United States, the second in 1953 by Russia (then the USSR). Great Britain, France, and China have also exploded thermonuclear bombs, and these five nations comprise the so-called nuclear club—nations that have the capability to produce nuclear weapons and admit to maintaining an inventory of them. Several other nations either have tested thermonuclear devices or claim to have the capability to produce them, but officially state that they do not maintain a stockpile of such weapons; among these are India, Israel, and Pakistan. South Africas apartheid regime built six nuclear bombs but dismantled them later. What is Hydrogen Bomb? Hydrogen bomb is based on nuclear fusion reaction and it deriving a large portion of its energy from the nuclear fusion of hydrogenisotopes. The hydrogen bomb functions by the fusion, or joining together, of lighter elements into heavier elements.The hydrogen bomb is also known as a thermonuclear bomb because extremely high temperatures are required in order to initiate fusion reactions. Hydrogen bomb is based on process called â€Å"Nuclear fusion†. Nuclear fusion is the process by which atomic nuclei join together to form a heavier nucleus. The fusion of two nuclei with lower mass thaniron generally releases energy while the fusion of nuclei heavier than iron absorbs energy. In the simplest case of hydrogen fusion, two protons have to be brought close enough for their mutual electric repulsion to be overcome by thenuclear forceand the subsequent release of energy. H2+H3⇒He4+n+Q Energy release Q=17.6 MeV Design of hydrogen bomb All thermonuclear weapons existing in the world today appear to be based on a scheme usually called the Teller-Ulam design†. It contain the Staged explosion of fission (primary) bomb and fusion (secondary bomb). The fusion bomb is triggered by rapid shock driven compression (Ulam) which is enhanced by radiation pressure (Teller) from released X-ray and ÃŽ ³-ray flux. Primary fision device contain :- core: U239 and U235 plus H2+H3 Booster shell: U238 Tamper High explosive lenses Secondary fusion device contain:- Radiation Channel U239 PU spark plug Li6 ,H2 ,H3 fusion cell U238 Tamper Design of modern Hydrogen-bomb Hydrogen bomb design is based on a bomb casing containing implosion fission bomb and a cylinder casing of U238 tamper). Within the tamper is the Li6 Deuteride fusion fuel and ahollow rod of Pu239 in the centre of the cylinder. Separating the cylinder from the implosion bomb is a shield of U238 and plastic foam that fills the remaining space in the bomb casing The detonation of the trigger bomb will cause the following sequence of events: The fission bomb implodes, emitting X-rays. X-rays heat the interior of the bomb and the tamper prevents premature detonation of the fuel. The heat causes the tamper to expand and burn away,exerting pressure inward against the lithium deuterate. The lithium deuterate is squeezed by about 30-fold. The compression shock waves initiates fission in the plutonium rod. The fission rod gives off radiation, heat and neutrons. The neutrons enter the lithium deuterate and generate tritium. The combination of high temperature and pressure is sufficient for tritium-deuterium and deuterium-deuterium fusion reactions to occur ,producing more heat, radiation and neutrons. The neutrons from the fusion reactions induced fission in the uranium 238 pieces from the tamper and shield. Fission of the tamper and shield pieces produced even more radiation and heat . The bomb explodes. USES AND APPLICATIONS Hydrogen bombs are used as weapons in many countries. Apart from their use as weapons,nuclear explosiveshave been also tested and used for variousnon-military uses. When long term health and clean-up costs were included, there was no economic advantage over conventional explosives. Synthetic elements such aseinsteiniumandfermium, created by neutron bombardment of uranium and plutonium during thermonuclear explosions, were discovered in the first thermonuclear bomb test. In 2008 the worldwide presence of new isotopes from atmospheric testing beginning in the 1950s was developed into a reliable way of detecting art forgeries, as all paintings created after that period contain traces ofcesium-137andstrontium-90, isotopes that did not exist in nature before 1945. An important aspect of fusion energy in contrast to many other energy sources is that the cost of production isinelastic. The cost of wind energy, for example, goes up as the optimal locations are developed first, while further generators must be sited in less ideal conditions. With fusion energy, the production cost will not increase much, even if large numbers of plants are built. It has been suggested that even 100 times the current energy consumption of the world is possible.Some problems which are expected to be an issue in this century such asfresh water shortagescan actually be regarded merely as problems of energy supply. For example, in desalinationplants,seawatercan be purified throughdistillationorreverse osmosis. However, these processes are energy intensive. Even if the first fusion plants are not competitive with alternative sources, fusion could still become competitive if large scale desalination requires more power than the alternatives are able to provide.Despite being technicallynon-renewable, fusion power has many of the benefits of long-term renewable energy sources as well as some of the benefits of the much more limited energy sources as hydrocarbons and nuclear fission. Like these c urrently dominant energy sources, fusion could provide very high power-generation density and uninterrupted power delivery. RESULT AND DISCUSSION In 1945 an atomic bomb was dropped on Hiroshima, it killed at least 70,000 Japanese and many were injured. It is assumed that the hydrogen bomb is 1000 times more powerful than an atomic bomb.[5] So if we use fusion power as source of energy rather than weapons then it should be more beneficial for us. Fusion power would provide much more energy for a given weight of fuel than any technology currently in use,and the fuel itself (primarilydeuterium) exists abundantly in the Earths ocean: about 1 in 6500 hydrogen atoms in seawater is deuterium.Although this may seem a low proportion (about 0.015%), because nuclear fusion reactions are so much more energetic than chemical combustion and seawater is easier to access and more plentiful than fossil fuels, some experts estimate that fusion could supply the worlds energy needs for millions of years. Therefore Hydrogen bomb has both advantages and disadvantages but if we use fusion power as energy source then it should be more beneficial for all of us.

Gay Marriage and Hawaii Sovereignty :: Politics Political Gays Hawaii Essays

"Lesbian/gay work sits on a lily pad. The lily pad is the foundation, the Kanaka Maoli struggle: the beautiful pink flower is the lesbian/gay work." —Ku’umeaaloha Gomes (1) â€Å"It’s a big industry, the exotification of Hawaii and its people, making it into every white man’s paradise. It’s nice now that we have ownership of our own stories.† —Lois-Ann Yamanaka (2) Hawaii is arrival. To arrive in Hawaii is to follow all of history, one group at a time. To the Kanaka Maoli, the people who first traveled in ancient times across the ocean in canoes and small boats from Polynesia, Hawaii was the promised land. It was the end of their pilgrimage, the land of powerful spirits and gods in need of worship. The Kanaka Maoli developed a complex society around this new land and these new spirits; a free society built around peace, love, and worship of one’s homeland. This way of life flourished for thousands of years, until the arrival of Christian missionaries in the 18th and 19th centuries declared their freedom evil, their nakedness vile, and their gods false. Christianity flooded the shores of the islands, pulling with it white entrepreneurs, who set up massive farms and plantations to take advantage of Hawaii’s unique agriculture, and Japanese workers for those plantations, with whom Christianity gained its strongest base in the i slands. Then came the political opportunists, who in less than one century pulled the Hawaiian monarchy up to its highest levels of Western pomp and circumstance, only to tear it down again with the overthrow of Queen Liliu’okalani in 1893 with help from the United States Government (who later annexed the island chain). Next came the arrival of the expatriates; the tourists; the haoles (whites) who saw Hawaii as nothing more than a tropical novelty or an escape from their stress-filled lives back on the mainland. Statehood came quickly in 1959, as did immigrants from the Phillipines and Korea. I came in 1995, with my haole military family, to a land that would become my adopted home the way it had for so many others. I found a land carved up like a puzzle; each person, each culture, each idea holding onto their piece with the will of God or gods. Today, there are many Hawaii’s. Depending on where you go, you can witness the poor, the rich, the privileged, the op pressed, the loud, the silent, the passive, and the active.
