Biology - Essay Example Each of these topics is discussed in the report as follows. 1. Central Jersey Blood Center: With a vision to provide supply of blood to people in need, the Central Jersey Blood Center has three centers in New Jersey for the donation of blood. The blood that is collected through these centers is primarily meant for use in the area hospitals. The blood donated can be of use to the premature babies, victims of burns, cancer patients, patients suffering from heart diseases, and any other patient who would be in the need of blood. Some of the hospitals whom the Central Jersey Blood Center provides with blood supply are Bayshore Community Hospital in Holmdel, Ocean Medical Center in Brick, Kimball Medical Center in Lakewood, among others (Central New Jersey’s blood center: Three blood donor centers and blood drives save lives). Thus the Central Jersey Blood Center can be understood to perform a significant role through their collection and supply of blood to the needy patients in th e hospitals in the area. 2. HIV and AIDS: AIDS or Acquired Immune Deficiency Syndrome is caused by the HIV or Human Immunodeficiency Virus. An infection caused by the virus later develops in to the syndrome. An individual infected with the virus is referred to as HIV positive. Although symptoms might not be visible even if the infection has occurred, treatment is necessary. If treatment is not considered timely, the infection might result in AIDS. The disease affects the immune system of a body. The immune system of the infected individual fails and the count of cells becomes lesser than that of a normal human being. AIDS may not kill a person. However, a person having AIDS may suffer from other diseases and death might occur as a result of the person not being able to fight the disease (Stolley, Kathy S. & John E. Glass, 3-5). Thus AIDS caused by HIV can be understood to be a syndrome that completely destroys the immune system of the human body. 3. St. Francis Counseling Center on Abusive Relationships: St. Francis Psychotherapy and Counseling Center is a center for counseling that deals with providing solutions to relationships involving troubles, or when abusive behavior tends to impact the people who are bonded in a relationship or a family. This might even include child abuses. This counseling center provides counseling measures irrespective of the background of the family or of the individuals who come for help. The center makes use of different therapies for their psychotherapy and counseling techniques. Such therapies include understanding what the problem is and what causes a relation to involve abusive attitude in it. Depending on such counseling and understanding of the nature of the problem, further therapies and problem solution measures are applied by the center to improve the relationship (St. Francis Psychotherapy and Counseling Center). Thus St. Francis Psychotherapy and Counseling Center can be understood to be an efficient center of counseli ng benefiting several families and relationships suffering from abusive behavior and leading to improvement. 4. Family Planning Services and Features: The Family Planning Center of Ocean County provides with the reproductive health care facilities for women and teenagers (About Us). This center also helps college students through several educational services. They intend to create awareness among the teenagers and the college students and thus provide with teachings on various issues related to the reproductive systems. The different topics on which the center provides educational services thus helping the college students as well, include abstinence, contraception and the associated risks and benefits, sexually transmitted infections, HIV and the risks

The Impact of Technology on Criminal Justice Essay - 1

The Impact of Technology on Criminal Justice - Essay Example Reflecting on the above understanding, this paper critically examines the impact of technology on criminal justice from a broad point of view. Research records that technological advancements have been developing fast-paced and unabated and more so within all realms of life from physical to biological. This encompasses advances in computing, robotics, artificial intelligence, genetics, neuroscience, biotechnology with these just but a few. Despite the fact that information technology has resulted to developments in various sectors, it has also some limitations. However, in this section we will examine how technology has had impact on criminal justice from a broad point of view. Technology has undoubtedly shifted the paradigms of crime with both police and criminals evolving like mutants (Cole, 2007, p. 26). With either side seeking to keep at pace with technology, there unravels a race but with which the police are expected to always maintain an upper-hand.the reason for this is because the police are mandated to protect the innocent public and with the support from respective governments, they are under constant pressure to subdue criminals (Hall, 2008, p. 39). Occasionally criminals get the upper-hand and commit severe crimes then manage to slip through from police who normally would be hot on their heels. Ideal embodiments for such incidents include the infamous Mumbai terrorist attack in India where many dozens were killed in a hostage siege in a five-star hotel (Schaefer, 2012). Other than possessing lethal weaponry, they used smart phones, satellite imagery and night vision goggles to locate their victims (Mark Goodman). The terrorists also had an operations center across the border in Pakistan that they used to monitor global news and social media in real time, and leveraging public photos, videos to kill more people. FBI, last year, seized a remotely-controlled robotic aircraft riddled with explosives bound for US

Distinguishing between authoritative sources and non-authoritative ones In order to write a good scholarly paper, one has to be aware of how to distinguish between authoritative sources and non-authoritative ones. One of the criteria that is used to distinguish between the two is the credibility of the author. In most authoritative sources, the authors’ credentials are normally given in detail. Other criteria that can be used to check the authoritativeness of source is evaluating the use of evidence and critical analysis of the evidence presented. 3. Examples of authoritative sources: Peer Reviewed journals UN research reports Audit reports for companies The information contained in these sources is normally based on evidence and through research. The authors of these documents are credible and the information contained in their findings is easily verifiable. Examples of non-authoritative sources: Personal blogs Social networks Free online encyclopedias such as Wikipedia Th ese sources normally do not contain substantive information. The information found in these sources in mainly personal opinion which in many instances is not backed by any hard evidence (MW Consulting, 2008). Response on Postings The first posting contains a brief and clear definition of an authoritative source.

History of voice coil of a speaker Research Paper

History of voice coil of a speaker - Research Paper Example A voice coil in a speaker is the loop of a wire connected to the top side of a loudspeaker conduit. Its main function is to give the motive force to the conduit by use of magnetic field created by current passing through it. The common loudspeaker that is currently in use was developed in the 1920s and uses a magnetic force to move a coil that is attached to a diaphragm. Information passing capabilities of a system through a magnetic-core, memory circuits and peripheral magnetic storage and retrieval devices was a challenge that faced traditional scientists. Although the history of voice coil technologies is particularly complex and tumultuous. Voice coil has been made in linear and rotary designs, but the rotary design has become the dominant design because it requires less space (Kamm, 1996). A much less expensive mechanism is a stepper motor, in which a shaft rotates in discrete steps to new positions in response to changes in the surrounding magnetic field. The functioning of the voice coil and related associates is closely related to the history of magnetism. It is recorded that around 1820’s a scientist, Hans Christian, demonstrated that magnetism was linked to electric current through the use of a wire carrying an electric current close to a magnetic field. This caused a deflection of the compass needle, which was being used at the tim e of the experiment (Schilders, Vorst, & Rommes, 2008). It is important to note that current flows causes the emergence of a magnetic field in the neighboring field. The history of voice coil indicates how abstract scientists ideas of this device has been ongoing since the invention of magnetism. Before any concrete advances could be made utilizing magnetism, scientists needed new tools and techniques that could be used to hear sound from a speaker (Brauer, 2006). One of the challenge was an inability to construct novel experimental materials with the

Does specialization must lead to an evolutionary dead end Term Paper

Does specialization must lead to an evolutionary dead end - Term Paper Example The term ‘specialist’ refers to organisms that are adapted to a narrow range of environmental conditions and thus occupy one extreme of the adaptation band. On the other end are ‘generalists’, which are able to utilize a wider range of environmental conditions. Factors such as â€Å"jack of all, master of none† and freedom from natural enemies, have been used to justify the prevalence of specialists, however; it has also been postulated that in spite of these advantages, specialization would gradually lead to loss of genetic variations, thus disabling capacity of adaptation to altered set of environmental conditions. These factors would eventually lead to extinction of a specialized organism, a theory first put forward by Cope IN 1896 and termed â€Å"law of the unspecialized† (Kelly and Farrel, 1998). Another implication of this concept is that the specialists are derived from generalists and the change is irreversible. This theory has been ch allenged by larger number of recent studies, and the evidences contradicting the implications of this theory are mounting. These evidences have proved that either no directionality exists in the evolution of specialists and generalists or that the generalists have evolved from specialist ancestors (Stireman III, 2005). In either case specialization definitely does not lead to an evolutionary dead end. That this trend is not an exception or restricted to a few taxa, is evidenced by the fact that such reports are available for organisms belonging to varied phyla including angiosperms, insects, fishes, mammals and microorganisms. This paper aims to prove that specialization does not definitely lead to an evolutionary dead end using evidences from relevant researches on floral plants, parasites, and mammals. As further evidence of this concept a plausible mechanism through which transition of specialist to generalist has been reported to occur will also be discussed. II. EVIDENCES FROM FLORAL PLANTS Floral plants depend on various species acting as pollen vectors for the completion of their reproductive cycle. Thus pollen biology is an integral part of study of evolution of floral plants. Darwin had stressed the importance of the role of pollen vectors in the reproduction of floral plants and its ecological and evolutionary significance (Harder and Aizen, 2010). Specialization of plants in context to their pollination apparatus and pollinators has major impact on the diversification of the species and is of paramount significance in its sympatric reproductive isolation, even leading to speciation (Gegear and Burns, 2007). Cope’s law has been traditionally applied to pollination biology as well and the hypothesis that specialized pollination systems have evolved from ancestral generalized systems has been accepted unchallenged. This has neither been established nor studied. However, among the recent reports challenging the universality of Cope’s law, some belong to highly specific dependence of floral plants and their pollination vectors. The genera Ruellia with approximately 300 species is characterized by diverse floral morphology and varied pollinators namely bees, hummingbirds, hawk moths, bats, butterflies etc.

What Important Role Did Emil Sodersteen Play in Australian Art Deco Research Paper

What Important Role Did Emil Sodersteen Play in Australian Art Deco Architectural Design - Research Paper Example It introduced in Architecture irregular shape, curved lines, curved glass, mosaic, and stained glass. This new style flourished in European Architecture. Art Deco was a continuation of Art Nouveau. It offered in the twentieth century’s design - luxury, style and efficiency. It emerged in the years of 1908-1912. Representatives of this design style are Tamara de Lempicka, Rene Lalique, William van Alens, Raymond hood and Paul Manship.3 Art Deco reached its flourishing between the years 1925 and 1935 years. The name Art Deco came from the Exposition Internationale des arts Decoratifs et Industriels Modernes. It was an art and craft exhibition, which took place in 1925 in France.4 The exhibition, demonstrated the latest achievements in the field of architecture, interior, furniture, metal products, glass, and ceramic designs. Six months of the exhibition period drew about 16 million visitors from different parts of the world. The exhibition was gorgeous and glamorous. The famous French architect Le Corbusier, one of the founders of constructivism and functionalism, for this exhibition designed and built the pavilion by name  «Esprit Nouveau ». The famous painter P. Lalique built another pavilion with colored glass fountain with light effects. The 1925 Paris exhibition, as whole, became the final stage of development of design of the period of Modern or a transitional stage form of Modernism to post-war functionalism. In 1966, after the revival of 1925 exhibition in Paris, this art design style received the name Art Deco. Before that, the style was called "jazz modern," "zigzag modern", "streamlined modern". New discoveries of spectacular monuments of ancient Egyptian art (including the tomb of Tutankhamen, 1922) and the ancient civilizations of America made a significant impact on the development of Art Deco design style. In the period, between the two world wars, Art Deco was used in decorative art; today the term has become the synonym of ef ficiency. Art Deco design artists offered glamour and efficiency in their work. Art Laurence, one of the brilliant Art Deco artists, combined in his work classicism, symmetry, straightforwardness, and cubism on one hand as a part of Art Nouveau, and on other the ancient art of the Egypt, Middle East, Africa and the Americas. Thus, Art Deco in design accepted on one side favorite themes and motives of Modern - more precisely the style of art Nouveau, - which were winding lines, an unusual combination of expensive and exotic materials, images of exotic creatures, wave form, and on the other side colorful designs, ornate carvings, visual abstraction, and abstract _______________________ 5. â€Å"Decorating in the Art Deco  Style,† Art Deco Style- Decorating in Art Deco Style, accessed May16, 2012, interiordec.about.com/od/stylesofdecor/a/art_deco_style.htm. 6. â€Å"Lalique Crystal, Figurines, Glass, and Art,† Squidoo, accessed May16, 2012, www.squidoo.com †º Home & Garden †º Home Decor. expressionism of the past.

The Efficacy of the Ghanaian Democratic Experiment Essay Example for Free

The Efficacy of the Ghanaian Democratic Experiment Essay The hackneyed, yet apt and succinct, definition of Democracy by Abraham Lincoln as contained in the concluding part of his famous Gettysburg Address as ‘’†¦government of the people, by the people, for the people†¦Ã¢â‚¬â„¢Ã¢â‚¬â„¢ remains today as the most quoted statement on Democracy. However, a careful examination of our democratic experiment leaves one to wonder if this definition perfectly encapsulates our experience. Our government is, granted, elected by the ordinary people, which bears testimony to the fact that we practise a form of democracy which is ‘’of the people’’. However, I contend that our form of government is not a government whose workings have, wholly, over the years, proven to be in the interest of the people. We are constantly saddled with the unfortunate and despicably capricious abrupt abrogation of government’s contracts shortly after a change from one democratically-elected head of state to another of different political persuasions. Our constitution, under The Directive Principles of State Policy, explicitly, states in Article 35, Clause (7) that, ‘’As far as practicable, a government shall continue and execute projects and programmes commenced by the previous Governments.’’ When a successive Government arbitrarily abrogates a contract, most of the time for political expediency, those who bear the brunt of this ill-advised action have always been the ordinary tax payer. Classic cases in point are the payments of judgment debts by the current and previous Governments, which were shrouded in some amount of secrecy until recent revelations. Governments engage in this reprehensible act in a sophomoric attempt to make their predecessors unpopular. Such a practice does not engender development, which democracy seeks to attain for all. Democracy must result in meaningful development for the populace, otherwise it is of no significance; we do not practise democracy just for the sake of it. It is to afford every single citizen a say in the way the country is governed, and, eventually, respond to their needs. I strongly believe this problem is, partly, caused by the lack of a common national development policy to guide our governments. The deep partisan nature of our politics makes it impossible for government and opposition parties to agree on a common development objectives. Our politics is characterised by the continual applause by Government for doing better than any government of the opposition and the continual representation of Government by the opposition parties for having done nothing. Sadly enough, this happens to be the case in most Western countries,too, and it always raises the question if we cannot adapt our democracy to our peculiar circumstances? For instance, I was surprised to hear that Mitt Romney, the presidential candidate of the Republican Party in the United States of America, who incidentally happened to be the person I was rooting for in last year’s American Presidential Election, imprudently, chose to attack the Obama Administration over the deaths of the US Ambassador to Libya and some American officials who were working at the embassy. I thought that in such a solemn moment, Romney would exercise some political maturity and join President Obama to issue a statement to the friends and family of those who died. But this is how far political opposition can take us! And it is no different from what we, sometimes, witness in our homeland. Political parties in and out of government oppose each other for no tangible reasons. Looking at the development deficits of our nation, it is imperative that we adapt our democracy to be more responsive to the developmental needs of the ordinary people. Another reason that makes me doubt if our democracy is really ‘’for the people’’ is the unfortunate level of participation of the Ghanaian in our democratic experiment. Again, under the aforementioned Directive Principles of State Policy, the Constitution states, inter alia, in Article 35, Clause (6), paragraph (d) that the State shall afford all possible opportunities to the people in decision-making at ever y level in national life and in government. This, to me, sounds pretty laudable in print, but in practice, the story is completely different: The only moment the Ghanaian really takes any decision in our national life is when it is time to elect Members of Parliament and the President. Beyond that time, the Ghanaian becomes merely a passive participant in the governance of the country. We usually hear refrains of ‘’Participatory Democracy’’ in the media being trumpeted by some state institutions, but, unfortunately, our Democracy does not have any real elements to showcase for that. I believe that our Democracy would be more participatory if we create more educated people, who understand the actual essence and imperatives of democratic governance. This, I suspect, would enable the greatest masses of the people to get actively engaged in the entire governance process of the country, and not merely always wait for every four years to queue up to vote. To this end, I fervently pray that Government and all other stakeholders would invest heavily in the education of our people since it is an open secret that true democracy can only thrive on an informed citizenry. And for one to be informed, one needs to have the ability to appreciate the national issues of concern; one must possess the ability of separating useless propaganda from issues which present all sides in an objective manner. This can only be achieved if the citizenry have some appreciable level of education. Another issue that worries me greatly is how our democratic practice is becoming more and more expensive. Most political parties in opposition always promise to have slimmer Government when voted into power, but we all know what happens after they win power. It costs a lot to maintain just one minister of state. Lately, we see more people working at the Presidency, some even without any official designation. It has become common to see lots of Government functionaries who describe themselves as being part of Government Communication Team. All these people are paid with the Tax Payer’s money! It is important that, as a nation, we do something drastic about our size of Government. Let us, however, not for once, delude ourselves into thinking that this problem is peculiar to the executive arm of Government. The most nauseating development, lately, in our national politics is the ritual increase of the number of constituencies by the Electoral Commission almost every four years on the basis of its constitutional mandate given to it by Article 47, clause (5) of our constitution. The foregoing article states clearly that, ‘’The Electoral Commission shall review the division of Ghana into constituencies at intervals of not less than seven years, or within twelve months after the publication of the enumeration figures after the holding of a census of the population of Ghana, whichever is earlier, and may, as a result, alter the constituencies.’’ This constitutional provision is so clear and simple to understand. I am quite worried because the approach of the Commission to this constitutional duty is making it seem as though review of division into constituencies and altering of constituencies automatically mean an increase in their number. Review and alter are not synonymous with increase in any dictionary! When you do your calculations, you can be assured that within the next forty years the country cannot find a place to accommodate our Members of Parliament to conduct Government business if the commission does not stop this practice of increasing the constituencies regularly. Maybe the best way to deal with this problem is to set a ceiling for the number of Members of Parliament in the Constitution since from all indications, the Commission’s understanding of that provision is simply to increase the number of constituencies every eight years. Without doubt, the size of the legislative arm of Government is getting too large, and we must, without any delay, start taking measures to reduce it. Ghanaians deserve quality representation, not quantity. Some Members of Parliament do not make any contribution to parliamentary debates in the chamber of the House, and some, I understand, do not make any meaningful contribution at the committees’ level. The strong brouhaha over the creation of the forty-five new constituencies last year was quite expected. As much as the argument about the unfavourableness of the time, was, sincerely, perfectly in order, the popular belief that a country of twenty-four million is not too huge to warrant more than two hundred legislative representatives is just the point. In the first place, the Commission should not have even created the thirty constituencies in 2004. It is not a matter of legalities; it is a matter of common sense. Anytime any person opposes the creation of the new constituencies, the Commission quickly rebuts that it is its constitutional mandate. Well, the constitution talks of review, not necessarily an increase. Our democratic experiment may be fraught with some difficulties, but my most fervent prayer is that we should never allow any malcontent(s) to truncate this political system. I would hope that we invest in education and strengthening state institutions. These two exercises are critical to deepening democratic culture in our country. I pray that all Ghanaians would get their hands on deck so that we can move forward collectively to truly build a better Ghana.
