Invasive Exotic Species Essay Example | Topics and Well Written Essays - 1750 words

Invasive Exotic Species - Essay Example The scientific study of insects has its beginning as early as the sixteenth century. Entomologists classify insects based on their taxonomy into various groups known as apiology, coleopterology, dipterology, heteropterology, lepidoptrelogy, myrmecology, orthopetrology, trichoptrology (Triplehorn, 2005) Each entomologist spends his life in the study of any one of these groups. Insect identification is very difficult as the attributes distinguishing them are often invisible or unclear. The Exotic Species (Invasive species) Exotic species are defined as those organisms that are not specific or intrinsic to a particular area. (Naylor, 2001) Their origin is a different place than their place of living. Scientific study and results prove that some introduced species are a threat to the ecosystem in which they get transferred. More scientifically, Introduced species are â€Å"species that have become able to survive and reproduce outside the habitats they evolved or spread naturally† (Naylor, 2001). Species are introduced in a habitat usually while they are transported from one region to another. These introductions can be accidental or intentional. Intentional inductions by humans is done thinking that a certain group of species is some how beneficial to human beings. Invasive species are one sub group of introduced species that have an ill effect on their foreign ecosystem. They behave as pests (G. K. Meffe. 1998). These immigrants breed expand and develop at an exponential pace causing great damag e to the eco relations. Its effect is simply defined in three terms namely arrive, survive and thrive. There are many clauses for a species to become invasive. It has to find a suitable vector to transfer it from its habitat to another one. The climatic conditions of the new habitat must match closely with its previous habitat. It should be capable to survive in that habitat and also outperform the existing native species and has to start spreading throughout like a plague. (Townsend CR. 1991) Basically invasive species have a negative impact on the new ecosystem. Some of the characteristics for an invasive species are the mode of reproduction, Asexual as well as sexual reproduction, the ability to withstand a wide range of climatic conditions and the reproductive output. (Townsend CR. 1991) One of these species that is responsible for defoliation of trees is the Gypsy Moth. The Gypsy Moth The scientific name of gypsy moth is Lymantria dispar. It is commonly called as gypsy moth to symbolize its mobility, that is, the pace at which it covers an area and also European moth. It is of the order Lepidoptera, class insecta and phylum Arthropod. This moth has its origin basically from Europe, Asia and North Africa. (ent.msu.edu, 1997) The Gypsy Moth This moth has been introduced in the North America and East Coast in the year 1869. It was an intentional introduction of this moth. A French scientist named Lepold Trovelot who lived in Massachusetts has introduced this moth. He was experimenting different moths and silk worms for having better quality silk production (Forbush, 1896). He with the intension of breeding silk worms with other moths introduced the gypsy moth in North America. His experiment failed. Some of the moths brought by him

GBN Scenarios Essay Example | Topics and Well Written Essays - 1500 words

GBN Scenarios - Essay Example Following a five-year intensive research at Sample Laboratories, scientists have come up with a polymer that could act as a replacement for newsprint paper as the new medium for printing. It is fully recyclable, eliminating the need for the education sector to adopt the use of costly information technology as a medium for printing, teaching and learning. The polymer has been tried in several schools and printing presses and has been found to have similar qualities with paper for the retention of ink. However, this is not what makes the new polymer unique; it is its ability to be reused once the user has had enough of the printed material. According to Sample Laboratories, the ink printed on the polymer can be extracted after a period of up to 30 years, diluted in specified ratios, and reused. Therefore, unlike information technology that requires the education sector to readjust to a new form of teaching and learning, researchers have come up with a new material for doing things the old way, but now more sustainably than ever. Several stakeholders in the education sector have already recommended the discovery; however, they have warned institutions against using the polymer in its exclusivity. Since it is in the early stages of adoption, they recommend its simultaneous use with paper and digital based materials. It is likely that institutions may adopt the new technology even before the governments authorize its use in the education sector, especially since regulators have declared it safe for use. Sample Laboratories have encouraged the use of the paper substitute by giving enticing offers to their customers; including discounts for institutions that buy the new paper in bulk. In addition, the firm is giving ink freely to anyone who purchases their invention, which is accompanied by a 10-year warranty. Sample Laboratories are also offering the polymer cleaning solvent for

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

Democracy - Essay Example Lord Bryce states that democracy is â€Å"the form of government in which the ruling power is vested not in a particular class but in all the persons of a state†. Abraham Lincoln defined it as â€Å"democracy is the government of the people, by the people and for the people†. Carl Becker defined democracy as â€Å"a democratic form of government has always meant one in which the citizens, or a sufficient number of them to represent more or less effectively the common will, freely act from time to time, and according to established forms, to appoint or recall the magistrates and to enact or revoke the laws by which the community is governed† (Modern Democracy). Pre-Requisites of Democracy Democracy is a system, which is successful in a sound political system. Such an atmosphere can be created by enhancing the literacy rate, improved socialization, active involvement of citizens in national politics, replacement of sentimental and violent politics with rational thi nking and pacific means, entrance of acceptance and tolerance in political life, and superiority of the national interests. Democracy may flourish only if everyone is given opportunity to participate in political activities and exercise of state powers on basis of merit and ability. However, several professional politicians are creating monopoly in politics due to political ignorance and lack of awareness. Political parties and democracy are nothing without each other. About all states in the world have political parties and representative groups to strengthen the democratic form of government. Democracy develops through unionism, associations, interest groups, and pressure groups. They communicate national problems to people and opinions of the people are made. Democracy is such a political system, which ensures right of opposition and criticism to put government on the right track. While exercising its powers, government may ignore the charter and abuse powers. A strong opposition is therefore necessary to keep government within its limits. Media is often considered as the backbone of democratic system. It serves as a bridge between government and the people. The role of media in the development of democracy is essential, therefore its independence must be ensured. Furthermore, development of democracy requires that regionalism and sectarianism must be discouraged and even to be rooted-out. These things divert attention of government from welfare and development activities. As rulers are representatives, they are responsible before people. Accountability to check government acts results in increased life and quality of democratic systems. Judiciary in this regard is a type of check valve in the system. It must be independent and effective to preserve the rights of the community. Characteristic Conditions of Democracy In democratic states, all people, irrespective of any discrimination, are citizens. According to the traditional concepts, as Aristotle says, à ¢â‚¬Å"all persons of a state are not citizens as slaves†. It is democracy, which gave equal rights and opportunities even to both sexes and all inhabitants. In this form of government, no one is allowed to rule forever but government changes according to changing conditions. Periodical elections are scheduled to change governments peacefully and through constitutional means. Government is responsible before parliament in parliamentary form of government and representatives are responsible before the electorates. In this political system, representatives have desire for re-election that compels parliamentarians to respect people suggestions. Democratic system ensures that all decisions are made on majority basis and state administration is run according to the will of the majority.

Under the gold standard not only trade expanded but also international capital markets developed. It allowed considerable investments into enterprises in other industrializing, mineral-rich countries which benefited greatly the economies of these countries. The gold standard ensured the entrepreneurs engaged in international trade from foreign exchange

Crimes Essay Example for Free

Crimes Essay Crime prevention is a major responsibility of law enforcement organizations. It is necessary to promote and maintain peace and order to the community by executing measures that lessens or diminishes crime rates as impacted by lawbreakers in society. Several solutions bring about the decrease in crime rates in the community. These solutions do not only depend on the roles and responsibilities expected to be carried out by law enforcement agencies, but also require cooperation from the people in communities and the government. Crime prevention should be a group effort because the will to prevent crime is everyone’s concern. With this in mind, one possible solution for crime prevention is motivating the community to be vigilant and cooperative in responding to criminal offenses. Law enforcement agencies cannot prevent crime without the help of other members of the community. In this case, the roles of victims, witnesses, and whistleblowers are magnified. When victims, witnesses, and whistleblowers experience criminal offenses of any gravity or kind, they should report it to the police. This catches the attention of law enforcement agencies allowing them to respond to the situation in a timely and apposite manner. Aside from experiencing criminal offenses, people should be able to inform the police of concerns regarding potential offenses observed in the community. Staying one step ahead is better, and by informing the police of concerns or observations, law enforcement agencies are able to plan ahead to prevent crimes from happening. Another way to prevent crime is by being cautious or vigilant about oneself and his surroundings. People should take safety measures in order to protect themselves, their property, and other people from the harmful nature of offenses. This includes following tips on safety precautions as advised by the state, law enforcement agencies, and concerned citizens or private organizations (HCSO, 2008). Engaging in a joint effort by the neighborhood, such as the establishment of neighborhood watch groups, is also one possible way to reduce or eliminate crime. Crime prevention does not only necessitate cooperating with the police, but also with other members of the community. Neighborhood watch groups are composed of people from a neighborhood who are concerned with the community’s safety and are willing to provide assistance to law enforcement agencies for crime prevention. Through collaboration and teamwork, people in the neighborhood are able to counter crime by evaluating their neighborhood and determining what steps to take in order to increase peace and order in their area. (Solutions for America, 2003) Technology and innovation also play a major part in reducing or eliminating crimes committed by offenders in the community. Law enforcement agencies use information technology in order to prevent crime and capture offenders. Crime rates, data sheets, and other background information about crimes, criminals, usual victims, and environments where crimes take place, etc. re stored electronically in a database managed and maintained by law enforcement agencies. Through this system or database, law enforcement agencies are able to share or view this information whenever needed for reference when it comes to predicting criminals patterns of potential risks that may cause the rise in crime rate in a particular situation. (SCRA, 2008) Continuous research and innovative techniques are being employed by private organizations in order to improve technologies that are being used by law enforcement agencies. For instance, the National Law Enforcement and Corrections Technology Center or NLECTC is active in research and experimentation in order to improve the quality, features, and functions of law enforcement technologies, making them more suited for crime prevention and criminal capture. Since technology demands high fees, it is the role of the state or federal government to allocate funds for this cause because technological advancement improves the performance of law enforcement agencies. Using technology automates law enforcement work, making it more efficient and timely in crime prevention. SCRA, 2008) Some of the gadgets that law enforcement use that assists in reducing or eliminating crimes committed by offenders include lightweight body armors, drug-recognition tools (through pupil scanning), cars (such as the Lotus Exige S which increases road safety for police officers especially when in pursuit), gunshot location technologies (computer that supervises specific areas to detect gun shots), video intelligence softwares for computers (may be used in houses, business companies, etc. or surveillance purposes), LED Incapacitator (it is a flashlight which emits LED light that restrains individuals when they look directly at it), and armed robots (apparently, some robots are utilized by law enforcement agencies by arming it with taser guns. (Gizmag, 2008) Focusing on rehabilitating crime offenders is also a plausible way in preventing criminal offenses. Restorative Jus tice is one way of rehabilitating criminals in order to reintegrate them back into society. It includes motivating jailed offenders to contribute to the community as a form of penalty. Restorative Justice also focuses on restoring damages to the victim and the community as a result of criminal actions taken by offenders. As a way to pay for crime offenses committed by offenders, they should be able to take necessary actions to patch up the relationship between the victim and the community to the offender. Through the penalties imposed to criminals, they are able to learn how to become responsible and cooperative citizens who area belt to make the right decisions. Moreover, restorative justice eliminates recidivism because it provides offenders the chance to correct their mistakes and become a valuable and accountable part of society.
