Biology Genetics - Essay Example Ito ET. al. (1996) and Ryner et. al. (1996) shared that, sex differences in mating behavior and male sexual behavior among the Drosophila may be attributed to a single gene. Fru gene is created out of spliced transcripts from four distinct promoters. Lee et. al. (2000) added that, FruM is manifested in w2% of neurons in the Central Nervous System of male. These neurons are arranged into 21 distinct clusters in several regions of the ventral ganglia and brain, including some of the areas or regions implicated in male sexual behavior. Similarly, the complex behaviors of insects are related to the organization of their nervous system; the neural pathways from sensory to motor circuits must be properly explored to understand their behaviors; and focused also in the body electrophysiological nature (Lee, 2000). The male P1 transcripts according to Demir & Dickson (2005), encode male-specific proteins (FruM) which are both important and sufficient for male sexual behavior. The aforemention ed literatures and those which were cited under the discussions and implications are quite reliable which supported the study. This research postulated that there are several fruGAL4-expressing neurons which are interconnected in a circuit and are involved in male sexual behavior. This circuit can be named accordingly: Sensory, central, and motor components. Basically, the study is directed towards exploration o... It also intended to assess whether "fruGAL4 reproduces the endogenous pattern of fru P1 transcripts". To achieve these, the proponents conducted gene targeting for labeling and manipulation of neurons, whereby they particularly add the GAL4 exposed reading frame to the fru P1 transcripts. In other words, various GAL4-responsive UAS transgenes were utilized. In fact, they also have stained brains and anterior nerve cords from fruGAL4, UAS-nlacZ heterozygous males with anti- "-galactosidase (anti-"-gal) and anti- FruM antibodies. The membrane tethered GFP reporter (UAS-mCD8-GFP) was utilized to closely observe the actual projection patterns of fruGAL4 neurons among the males and to find out for the potential differences in these projections among the females. Aside from this, to find out whether fru GAL4 ORNs work in male courtship behavior, an FLP-in strategy analogous to that one being used for their anatomical characterization was employed.Single-pair courtship assays were also prep ared, in which males of these genotypes were joined to the wild-type virgin females. These assays were carried out in the dark in order to get rid of any visual cues that might affect or influence courtship, thereby increasing the male's reliance on chemosensory cues. Behavioral Assays, Immunohistochemistry and FLP-in-Silencing Constructs are all very powerful methods and fitted for the study. If we take a closer look on the assumptions and methods presented, the authors considered the classical as well as updated theories and principles for its variables. Thus, a very strong theoretical basis in the pursuit of the approaches or methods used has been established. Approaches utilized are congruent to the expected outcomes.

Events that left to the Civil War Essay Example | Topics and Well Written Essays - 1500 words

Events that left to the Civil War - Essay Example Most northerners had no problem with the idea of states rights. However, they believed that slavery was to be ruled by the United States federal law so no state had the right to secede when it came to this. This became a source of conflict between the north and south. As a result of this, antislavery groups made up of people calling themselves abolitionists were formed. Consequently people and especially the minority groups who were mainly slaves learned new ideas about human rights and freedom. With the fear that the federal government of the United States would force them to give up slavery, southern politicians opted to balance the number of free sates and slave states. 1Arnold points out that â€Å"if the number of free states was the same as the number of slave states, there was political balance.† The number of states that allowed slavery was thus eleven while eleven states banned slavery. Until 1820, conflict between the northern and southern states was avoided since th e number of free and slave states had remained equal. However, this balance was disturbed by the expansion of the United States west of river Mississippi. By 1820, many southerners had moved to the region of Missouri, and taken their slaves with them despite the fact that Missouri was geographically located in the north. In the same year Missouri became the first state in the territory of Louisiana to apply for admission into the Union. Missouri had thousands of slaves then so it was given that it would apply for admission as a slave state. This would however, distort the balance between free and slave states. Consequently, political leaders had to make agreements and compromises to keep the nation together. The United States House of Representatives was controlled by the north and there was no way it was going to allow slavery to expand in Missouri. To prevent the expansion of slavery, the House of Representatives passed a bill aimed and gradually eliminating slaves in Missouri. Ac cording to the bill, no new slaves were to be brought into Missouri, and children of Missouri slaves, upon reaching the age of twenty five would be declared free. Although the House of Representatives passed this law, it was turned down by the senate, which had equal representation of the north and the south. The problem with this bill was solved by Henry Clay, who proposed a compromise. To pacify the south, 2Hazen points out that â€Å"Clay suggested that Missouri be permitted to enter the Union as a slave state since that was what she already was in reality.† To appease the north, Clay suggested that slavery be barred for ever from the remaining regions of Louisiana territory. Meanwhile, Maine which had also applied for admission into the Union would be admitted as a free state. The solution would thus maintain a balance of twelve free and twelve slave states. After a long, bitter and ugly debate between the northern and southern congressmen, the Missouri Compromise was pas sed. Missouri was admitted into the union as a slave state while Maine was admitted as a free state and slavery was banned in the northern part of Louisiana territory. Consequently, peace between the north and the south was restored for several more decades. For several decades’ peace between the north and south was maintained by the Missouri Compromise. However, in 1850, the issue of slavery and its expansion surfaced again. In 1848, Gold

Significance of the thinking and writting on education (History of Research Paper

Significance of the thinking and writting on education (History of Education) - Research Paper Example As an educator, Webster’s vision was to maintain an American Christian republic where Christian values and moral principles were taught, valued and preserved. In short, Webster envisioned â€Å"an educational system that would impart, "a love of virtue, patriotism, and religion", based on scripture† (Pope 2010). Thomas Jefferson, on the other hand, regarded education as a key factor for the smooth function of democracy and he laid emphasis on education for all. He believed that only educated and well-informed citizens could play crucial roles in democracy; thus, for him education was the ‘foundation of democracy and a prerequisite to vote’. The four principles that governed Jefferson’s views on education were: â€Å"democracy cannot long exist without enlightenment†, â€Å"that it cannot function without wise and honest officials†, â€Å"that the talent and virtue, needed in a free society, should be educated regardless of wealth, birt h or other accidental condition† and â€Å"that the children of the poor must be thus educated at common expense† (Jewett 2010). Jefferson pointed out that States should be divided into small districts or wards for better educational outputs and for him the structure of education should be in four levels: elementary schools, grammar schools, universities, and life-long learning. However, Jefferson’s liberal views on education failed to accommodate the educational needs of women, Blacks or Native Americans. Pope, Randy. (2010).

Reward Management in Ikea Literature review Example | Topics and Well Written Essays - 1000 words

Reward Management in Ikea - Literature review Example Most organizations use reward management to motivate employees and enhance their productivity thereby contributing to improvement of overall organizational performance. Reward management is further aimed at ensuring internal, as well as external equity. More importantly, it strengthens psychological contract and also for organization to comply with legislation that require organizations to have reward management system (Phil and Cole, 2011, p. 101). Furthermore, reward management provides an organization with a system that enables it to efficiently administer rewards among employees. There are basically two types of rewards: extrinsic rewards and intrinsic rewards. Extrinsic rewards satisfy basic human needs such as security and survival and include raise in pay, better working conditions, and bonuses among others (Wright, 2004, p. 17). Intrinsic rewards aim at satisfying higher human needs such as development and esteem. The vision of IKEA is creation of better everyday life for man y people including its employees. Its human resource philosophy is that employees can be more productive and committed when the company is taking care of their needs. Like many Swedish companies, IKEA adopted a paternalistic stance towards the needs of employees and employees themselves that seeks to empower employees (IBS Center for Management Research, 2012). The application of its human resource philosophy is more or less standardized and reward policies are applied to all employees uniformly. Its human resource policies are aimed at making relationships between employees open and strong, and employees are encouraged to excel by taking care and supporting each other. In a nutshell, IKEA’s human resource policies seek to guarantee uniform and high quality standards in order to support its future developmental and business challenges (IBS Center for Management Research 2012). IKEA’s reward management system is designed to reward employees more or less equally and is i nformed by the need to make relationships between employees open and strong. Equity theory is relevant to IKEA’s reward management system. Armstrong and Stephens (2005, p. 92) note that this theory suggests that employees will be motivated to engage in actions that they perceive that the conditions of the situation are just and fair and which will ultimately benefit them. In addition, this theory holds that a person will be motivated towards organizational goals if they feel that the amount of effort being put forth commensurate the outcomes or the benefits being received (Byron and Khazanchi, 2010, p. 3). Considering that IKEA’s human resource policies are aimed at creating open and strong relationships among employees and empowering them, equity theory are more relevant to their reward management system. This is because it requires that this system regulates equity and help employees to maximize their outcomes as a whole. Looking into IKEA’s human resource pol icies also shows that the organization is keen to avoid distress among employees which might hamper its efforts towards attaining its goals. Equity theory will therefore be relevant to creating equal relationships among parties in the workplace thus avoiding distress. Equity theory recognizes commonly contributed inputs in organizations to include labor, personal investment, time, dedication, and skill (White and Druker, 2000, p. 81). Application of this

Next Weapon of Choice by Terrorist Research Paper

Next Weapon of Choice by Terrorist - Research Paper Example Pakistan is a country which possesses nuclear weapons. Moreover, it is a country where some of the infamous terrorist groups took shelter when most of the other countries closed doors for them. The political instability and weak governance of Pakistan is a matter of concern to many people because of the fear that Pakistan’s nuclear arsenal may one day come in the hands of the terrorists. Pakistan’s soft approach towards terrorists is not a secret to the external world. Biological and chemical weapons of mass destruction are another option for the terrorists in the future. The article written by Matusiak and published in has mentioned the possibilities of chemical weapons which may use by the terrorists in future  The author mentioned that the idea of a terror organization using a WMD is to strikes fear directly into its intended target population and to prove that the terror organization weapon of mass destruction is in its possession. More than 90% of the most danger ous facilities transport chemicals by rail. Over 80% of these facilities receive shipments of toxic gas chemicals, which is released can cause medical problems if inhaled (Matusiak, 2009). Low-end chemicals are mostly transported using rail or sea transport. Even though many safety laws and regulations are there for the manufacturing and distribution of low-end chemicals, no such laws are applicable or prevailing while transporting these materials. Rail and sea transport normally may not have much security compared to air transport. We have many recent incidents in which Somalia sea robbers capturing the control of commercial ships passing near the Somalia territory.  Ã‚  

Death Penalty Pro's Essay Example | Topics and Well Written Essays - 1250 words

Death Penalty Pro's - Essay Example A number of organizations have gone against death penalty, with convincing arguments surrounding its ineffectiveness in preventing future crimes, its cruelty and various other reasons. Listening to their arguments would make one think that the supporters of death penalty are nothing but cruel and inhumane individuals devoid of compassion and willing to kill, which is the very crime that they abhorred in the first place. One of the most vocal of all the activists is Amnesty International, which made a public declaration that "death penalty is the ultimate cruel, inhuman and degrading punishment." The group also believes that this type of punishment is a form of human rights violation, irrevocable, may be inflicted on the innocent, and does not certainly stop future crimes to be committed. Abolitionists back their claim with statistics and studies, although most of these studies have been misrepresentation of the truth. They have succeeded in their quest in a number of nations around the world. Amnesty International states that from the time that it started the movement against death penalty, the number of nations that have abolished death penalty from the judicial system has risen from 16 to 86 nations. Notwithstanding the strong opposition to death penalty, however, the American public continues to quietly support this form of punishment for heinous crimes. This support was even reinforced after the September 11 attack on the United States. It is reported that one-fifth of those who usually go against the death penalty feel that the terrorists who execute such crime against humanity deserve death sentence (Cable News Network). This goes to show that people feel that it is necessary to punish those who are willing to kill numerous others and still justify their murde rous actions. First among the arguments of opponents of the death penalty surrounds its ability to deter crime. They state that there is not enough statistical basis to say that the imposition of death penalty prevents further crimes from happening. Opponents even think that crime rates are higher for those states with death penalty statutes than those which do not adopt capital crime punishment. While it is difficult to convince people who have already made up their minds against death penalty, it should be emphasized that deterring crime is not solely the reason for exacting death penalty on those who committed heinous crimes. John McAdams aptly states that execution of murderers even without deterrent effect, would still be better as this will diminish the number of criminals in society than if they were left to live and with that inaction, people expect future crimes to be prevented (American Bar Association). Even as opponents of death penalty believe that the punishment does not ensure the d ecline in crime rates, they also do not provide enough evidence that inaction against doers of heinous crimes warrant the decrease the occurrence of crimes. George E. Pataki believes that death penalty is effective in preventing future crimes from happening, and that the government should use every action possible in order to protect

Developing a Philosophy of Education Essay Example for Free

Developing a Philosophy of Education Essay I believe the purposes of education are to instill knowledge, instill forms of proper behavior, instill values and principles in the minds of children, and include the development of skills, physical, mental and social. Formal education begins with primary and then secondary education and higher education. It is when we grow up we begin to achieve the purpose of education and understanding of its application in daily life. It is believed that education is to be responsible for the cultivation of a civilized society. Providing education for citizens manages to develop a responsible and thoughtful community. Education helps in imbibing moral and ethical values in individuals and education, in turn, helps in creating a healthy society, which holds a deep understanding of the principles and philosophy of life. The purpose of getting an education is to achieve progress in the areas of operation to enable every member of the community of learners to earn a living. Also, one of the beliefs about the purpose of education is that education aims to create a good teacher. I believe that students learn best when they are taught under certain conditions and in certain ways. Some of these include the student’s support and encouragement, give them self-confidence, and give them the opportunity to participate and discuss in the classroom. Also, teachers encourage them to be themselves and use their creativity. Gentle treatment and respectful treatment of students gives students a sense of comfort and the ability to be tender. The curriculum of any classroom should include certain â€Å"basics† that contribute to students’ intellectual, emotional, social, and physical development. These basics are activities that help them to read and write. As well as activities that help to open mental thinking such as mathematics. By doing so you will teach the student the skills needed. Students learn best in an environment that promotes learning. Some of the characteristics of a good learning environment are to be a sponsor of the learner environment and be keen to learning and development. A learning environment is comfortable and equipped with the necessary settings that help the student focus and pay attention in the classroom. Lighting, air conditioning and classroom size appropriate for the number of students that help the students focus. Should all be taken into account. A teacher should have certain qualities and behave in certain ways. Qualities I think are important for teaching are respect between the student and the teacher, which helps in the creation of the student values. The teacher must be patient and bear the mistakes of their students and help them to live. Be friendly in dealing so that students feel comfortable toward the teacher. That makes flexibility in communication between student and teacher. Creative teachers are able to motivate students by using creative and inspirational methods of teaching.
