The Arabidopsis Myb Genes MYR1 and MYR2 Essay Example | Topics and Well Written Essays - 750 words

The Arabidopsis Myb Genes MYR1 and MYR2 - Essay Example Arabidopsis is a long day plant that flowers earlier than other plants in long day conditions than in short day conditions. In LD conditions flowering is affected by an increase in expression of the flowering locus T (FT). This gene expression is controlled by CONSTANS (CO). Under low light intensity, homozygous myr1 and myr2 mutants will flower and show an increase in petiole length, apical dominance and leaf angle. Analysis on the genetics of the mutants point out that myr1 and myr 2 phenotype need GA biosynthesis. In determination of the functions of MYR1 and MYR2 roles in plant development and growth two independent T-DNA alleles for every gene. The T- DNA were evaluated and discovered that they eliminated full length expression of MYR1 and MYR2 in plants homozygous to every mutation. The homozygous myr1 and myr2 mutants happened to be identical to WT plants in relation to their leaf color, plant size and morphology. In SD conditions plants that had any of these alleles had an ea rly flowering and this generally indicates that myr1 and myr2 had suppressive effects on flowering. Additionally, flowering locust T was also needed by the Myr1 and Myr2 phenotype responsible for flowering and these mutants also demonstrated an interface with phyB-9 mutant. When Myr1 and Myr2 are over expressed, GA deficiency symptoms are shown which are then eliminated by use of gibberellic acid (GA1). When Myr1 and Myr2 were lost, there was a double boost in GA20ox2 expression and GA1 levels increased by 30%. Myr2 over expression caused a three time GA20ox2 decrease and 50% reduction in GA1 levels. Therefore, it can be concluded that Myr1 and Myr2 ability to limit flowering and elongation of organs is slightly because of their destructive consequence on the bioactive GA levels. In this case, it is possible that the increase in expression for the GA negative regulators showed the property of having a shade avoidance phenotype. The role of MYR1 and MYR2 of affecting the GA2O0x2 expr ession could be the determinant for observed phenotypes and it is in the same line with research on GA2O0x2 genes that indicate their importance in regulating growth and fertility of the Arabidopsis plant. This essay is based on a previous research done by several researchers. It will describe the result, outline the conclusion and give an insight on future work based on this research. In the result that has indicated that MYR1 and MYR2 have a role in plant growth and development, it is indicated that as light intensity became high, the phenotype became weak and double mutants of myr1 and myr2 produced fewer than WT, rosette leaves. In relation, vegetative growth and flowering time characteristic of the myr1 and myr2 mutants exhibited a similarity with phyB mutants. When MYR1 and MYR2 are paralogous and the genes are co-expressed, lengthening of the vegetative period in SD conditions showed a weakening in the phenotype responsible for early flowering. Myr1 and myr2 that were early f lowering under a LD environment was connected with more features that were not present in single mutants. They a longer petiole, lengthy hypocotyls and the leaves were more vertically oriented with a peak in apical dominance. This features show that the early flowering phenotype had been strengthened and that both myr1 and myr2 double mutants expressed the presence of MYR1 and MYR2 redundancy property which was not shown in the single mutant’s myr1 and myr2. In addition it was discovered that MYR1 and M

Marijuana Legalization Essay Example | Topics and Well Written Essays - 1250 words

Marijuana Legalization - Essay Example The most important reason for anyone to debate on the subject of marijuana legalization is because of its relevance to young people. Advocates of marijuana legalization in Washington, DC have voted on the legalization of marijuana and approved the move by an overwhelming majority. Kleiman mentions in his article that the district officials of the states are now looking to create a market for buying and selling of marijuana which was previously prohibited from selling under the ‘grow and give’ framework. In the article, Kleiman points out his argument against the creation of a profit motivated market for marijuana. It is true that commercialization of marijuana is disadvantageous. For one, it can cause many problems for states where marijuana is still illegal. Legalization of marijuana in Washington alone is likely to have its repercussions on other states where the drug is prohibited, a risk which also pointed out by Kleiman. Creation of an official market for marijuana will spark its trafficking to other states through underground channels. The most obvious impact is the rise in inter-state travelling in Washington for recreational usage of the drug. As such, there is a great likelihood that marijuana availability in Washington will result in easy acquisition and trafficking of the drug to other states. In his article, Mark Kleiman has argued against the commercialization of marijuana. Marijuana legalization comes at great social costs especially for the young user base of the illicit drug.

Stressors and Stress Management Mechanisms among First-Year School Dissertation

Stressors and Stress Management Mechanisms among First-Year School Principals - Dissertation Example Stressors and Stress Management Mechanisms among First-Year School Principals Thus, this period needs to be handled with a lot of care and precaution. Indeed, Lindley agrees, â€Å"professional training materials are needed to help educators who are preparing for administrative positions and first-year principals who are struggling to survive the tribulations of the â€Å"rookie† principal† (Lindley xi). The best way to do this is to investigate the various causes of stress among first year principals so that best way forward can be proposed to assist school administrators going through the same challenges. Since the issues of stress among first year school administrators is wide and multivariate, literature review is given a fivefold approach. First, literature regarding burnout theory is investigated. Secondly, literature review is done on stressors among first year principals. Thirdly, works regarding impact of stress experienced by school administrators is reviewed. Finally, literature work on authors who have focused on coping mechanisms is evaluated. Burnout can occur among professionals dealing with service to people. According to Dworkin burnout occurs when overstressed individuals feel emotionally drained by their work environment, feel that their activities result in no benefit to those they had intended to help or to themselves, and come to blame their clients, patients, or students for failing to improve, get better, or learn, and in turn, for the professional’s loss of feelings of accomplishment.... Although there are different burnout models, Maslach burnout theory as proposed by Maslach and Jackson is used. The Maslach burnout inventory (MBI) argues that burnout syndrome comprises of emotional exhaustion, depersonalization, and a feeling of reduced personal accomplishment. The burnout theory has mostly been used to assess the stress levels among professionals who do â€Å"people work.† Most of the earlier works utilizing burnout theory investigated causes of stress and stress levels among professionals in nursing and religious institutions. However, recent works investigating stress among school administrators have also used this theory with great levels of success. Indeed, â€Å"a number of studies have now reported on the reliability and validity of the Maslach Burnout Inventory in a variety of cultures and among a variety of different professional groups† (Greer and Moberg 180). Whereas, burnout theory has been used for quite some time in investigating stresso rs among school principals, â€Å"research on burnout has produced unanswered questions for school administrators† (Ward 46). It therefore becomes important to dig exhaustively in this subject in order to come up with viable solutions to the stress factors. Many authors have applied the MBI in their work on stress among school administrators. Among them was Ward from the University of Texas at San Antonio. Ward investigated the impact of personal and organizational factors on school administrators. Though his study was wide, one of the issues he investigated was the correlation between the levels of burnout and years of experience of school administrators. He used the MBI and found out that the first years of school administration are the most stressful. Vandenberghe and Huberman explored the

Gulf War Essay Example | Topics and Well Written Essays - 500 words

Gulf War - Essay Example The US military had done away with the war draft and so it is mainly a volunteer army. As such, it relies usually on people who freely and voluntarily join the military service and the people who enter the military are mostly poor people (the traditional party base of the Democratic Party). The sons and daughters of rich people do not join the military service. It is only the poor kids who join as a way out of poverty, get a sure job and obtain education. In other words, it is the lower social and economic classes which had borne the greatest burden of prosecuting the wars in Iraq in disproportionate numbers compared to the rich classes. However, the main reason why labor unions today are opposed to the Iraq war was it was a war that was not properly explained to them. The original objectives of going into Iraq were hazy at best which was to remove Iraq from Kuwait which is a recognized member of the United Nations as a sovereign nation. But more than that, the ordinary Americans are now more wary of getting involved in other people’s domestic affairs when the American citizens themselves are in deep trouble regarding their own issues about the economy, health care, education and many other concerns such as high crime rates. Americans today do not want to get involved because they had a bad experience with the Vietnam War (Brier 1).

Network Acquisition - Essay Example   In order to support the first rationale, identification is required of considerable hypothesis and restraint for the solutions that must meet the criteria  In order to secure the requirements and the criteria, alternative methods and concepts are recommended  Moreover, the project plan includes the classification of a business value for a system.   A request of a system demonstrates a comprehensive summary of business requirements along with the integration with the business process in order to develop a business value.   The concerned personnel or department who generates the request also called as project sponsor, works in parallel with the Information system department staff in order to perform feasibility study (Brown, DeHayes, Hoffer, Martin, & Perkins, 2009).   The outcomes of a feasibility study illustrate essential aspects of the proposed project via project sponsor. It involves economic feasibility, organizational feasibility, and organized feasibility. Moreove r, the project sponsor collectivizes all the funding and resources and deploys a project manager during the initiation phase.   Likewise, the concerned project manager requires developing communication with the business departments along with identifying prospects to enhance business processes.   Furthermore, the businesses processes are simplified by the project manager in terms of documentation that is provided to the project sponsor (Brown, DeHayes, Hoffer, Martin, & Perkins, 2009).

Staff Reduction Process Coursework Example | Topics and Well Written Essays - 250 words

Staff Reduction Process - Coursework Example The other responsibility of the correctional manager in the staff reduction process is ensuring the employees who are let go do not harbour hard feelings and are adequately compensated and the staff reduction is done in accordance with the law and in compliance with agreements and regulations stipulated in employment contracts (McConnell, 1993). Ensuring all other avenues including cost saving have been sought for and failed before undertaking a staff reduction is the other role of a correction officer in staff reduction. My reservations about staff reduction include the impact of the families and relation of the affected employees, having to let go of employees who have showed great potential, and the possibility of the employees getting new jobs. The measures to be confident as a manager in a staff reduction process include early preparation including all the facts pertaining to the reason for the reduction, the members affected, and the procedure for the selection of the members. Ensuring the reason for the termination is justifiable and easily presentable to the employee to be able to inform the employees clearly. Reviewing policies and procedures on staff reduction will also increase my confidence through providing statements to staff during the staff reduction meeting (The Ohio State University, April 17, 2014). Providing a memo to all the terminated staff on measures taken to ensure adequate compensation and writing recommendations also allows for better confidence. Adequate analysis and in-depth thinking on the employees to terminate to ensure the correct decision on the affected employees also aid in increasing confidence in dealing with a termination of

MSc Programme and project management Personal Statement

MSc Programme and project management - Personal Statement Example The PPM course is seen as an opportunity for me to put myself ahead of the increasing demand of the project and programme management job market. By putting myself a step ahead of the requirements of the job market, I can be assured that I will become what employers and project owners are looking for. But this striking vision needs to be nurtured and started somewhere and that is the course being applied to. Apart from the outstanding benefits I will derive from the course, one other reason that makes me prefer PPM is the fact that nature of the course matches who I am and what I have been able to achieve so far. First, I have a very good background in British education as I have successfully completed a four year BA business programme in Britain. This puts me in a better position to easily adapt to the British learning environment and requirements. Even though business studies and PPM are different, there is much similarity between the two, putting me at a better position to grabbing academic concepts very easily. For example it is common knowledge that most projects and programmes that require the expertise of project and programme managers are run by businesses. With my knowledge in business, I will therefore be able to have a very deep understanding of project owners. I can also have empathy for project managers in understanding issues of project urgency, cost saving, and quality co ntrol. My level of confidence expressed above as to why my background as a Business student can help me succeed with the PPM course can be backed by realistic academic abilities and achievement. For example as a Business student, I achieved very good grade in Finance, which I scored 79% and thus was graded A- in my course assignment. With my current GPA, I am confident about completing with a high 2.1 degree, which is a strong demonstration and evidence of attitude to academic work. With the
