Free Essays on Effects of Trust in Management

Introduction A few weeks ago, I was watching the evening news with a friend of mine. A breaking story came on announcing Arthur Anderson’s use of unethical accounting practices in the Enron scandal. I asked Shannon if she knew anything about the firm’s involvement, and she said in disbelief that she had not. The interesting fact here is that Shannon works for Anderson Consulting. In that moment, she lost all trust in the company and is now looking for a new job. Trust plays a pivotal role in every corporation’s daily activities; it can be a specific management tactic, or a mediating variable in a work team. Increased trust between managers and subordinates will lead to increased productivity and job commitment. However, this type of persuasive discourse is often very difficult to consciously achieve because of the numerous factors involved. This paper will address contemporary ideas on establishing trust in organizations, its effects and includes an informal study on the use of managerial trust. Literature Review Over the past few years, the topic of trust in management has received much scholarly attention. The fall of Enron and other such recent scandals where hundreds of employees lost their jobs may explain this. As Caudron (1996) explains it, â€Å"Management has lost all credibility, employees are scared, and organizational trust has hit rock bottom.† An article by Ellen Whitener et al. (1998) explores the many practices managers must engage in to gain employee trust. She begins by defining managerial trust in three facets. First, trust relies on the trustor’s belief that the trustee will act benevolently. Second, trust relies on the concept that risk is involved. Third, there is some degree of dependency in the relationship (Whitener, p. 513). Here, trust is viewed as an attitude the trustor has about the trustee. Whitener uses two theories to analyze the motivation behind trust strategies, agen...

Understanding Practical Business and Organizational Research Assignment

Understanding Practical Business and Organizational Research - Assignment Example The study elucidates the huge problem of poor performance, accountability, and transparency in the government institutions such as municipalities. The Americans have expressed their dissatisfaction of the delivery of services in the government institutions. On the other hand, the purpose of the study was to evaluate the contribution of performance measure to the sustainable improvement, accountability, and transparency of the government organization (Sanger, 2012). The research hypothesized that cities that had sophisticated performance measurement systems would have a high likelihood of using the performance data to improve performance. However, the research did not have research questions. The study used an analytic approach to collect quantitative data from a sample of 190 cities. The researchers searched the cities with a high likelihood of measuring performance with the intent of improving service delivery (Sanger, 2012). Fundamentally, the researchers selected a sample from four service areas namely police, parks and recreation, fire, and public works. The study used quantitative approaches to analyze the data and present it in tables. The study findings are important for the city mayors and officials who hold leadership positions to implement the information gotten from performance measurement for the betterment of services. In summary, the researchers established that government institutions rarely implement the information from performance measurements for the improvement of services. The data analysis indicates that few organizations use the information to improve service delivery. The analytic approach used in this study can be applied to solve performance problems. The researchers have analyzed the problem by seeking the primary data of the various cities. Primary data establishes the main cause of a problem, and thus provides a platform for selecting the best solution (Zikmund, 2013). For

John Wycliff's contribtions to the christian religion Term Paper

John Wycliff's contribtions to the christian religion - Term Paper Example Other individuals believed in giving out offerings so that they can receive forgiveness for their sins (McDonald 139). John Wycliffe acquired his college education at Morten College at Oxford, which acted as a fundamental tool in his career. This is becoming a significant and reputable icon towards building Christian faith. During Wycliffe’s time, the church had a dominant force in almost all areas of life. The church utilized its power to exploit fellow Christians in a variety of ways. For instance, Christians were to pay for their sins whereby mode of payment was money or gifts meant for the ministers (Phillips 26). Most people were in bondage of the church and its sacraments based on how it expressed and ensured its power manipulated Christians. This prompted Wycliffe turned out to be the then fearless critical of the church’s abuse of power (Davis 98). Hence, becoming popular due to his stern stand and criticism on the church though he based his arguments on the word. The then secular government was an example of a reputable organization that boosted and sided with him in its quest to reveal how the church had become and taken advantage of its congregation’s ignorance. Government’s support was in form of preventing the church from directly condemning the emergent critic whose arguments were justifiable besides the church some of the dealings being unbiblical. Wycliffe was also a significant workforce in the reformation of the church. During his time, the church seemed own a large area of England besides having an unconquerable influence (Lavinsky). Instances of corruption characterized the mainstream church more so the clergy taking advantage of the ignorant faithful. In addition, the clergy contrary to what their vows stated proved to be immoral besides sometimes allowed to pass certain stages without accomplishing the required measures, hence the church during then producing illiterate priests (McDonald

Urban Studies and Planning Essay Example | Topics and Well Written Essays - 1000 words

Urban Studies and Planning - Essay Example All these careers are exciting and personally fulfilling in the sense that they are well paying, challenging, and they give one an opportunity to grow. The urge of using my skills to establish a community where people can live and start families makes a career as an urban planner to be my first priority. I understand that a college degree in addition to extensive training is a requirement for a successful entry into this field of work. To qualify as an urban planner, one needs to take classes on environmental studies so as to understand the interactions between people and the natural environment as well as the dynamics of the environment. Moreover, a person needs to take classes on economics so as to comprehend how the markets operate, particularly, what makes a successful regional economy and business. Additionally, one needs to take classes in art and design so as to prepare oneself to think creatively about visual appearances. The prospect of getting employed as an urban planner is also high. First, there are many institutions, both public and private that hire urban planners. With a degree in urban planning together with the required experience, I can be hired by local/regional governments, private planning firms, and private property owners to facilitate the planning of commercial and communal developments, as well as transportation systems and public facilities (Bayer, Frank, & Valerius, 2009). Secondly, urba n planning is a growing field of employment. As Bayer, Frank & Valerius (2009) put it, the roles of urban planners remain in high demand, and is expected to grow significantly by 2014. For example, the U.S News and Urban Report rated urban and regional planner among the best careers in 2009 (U.S News, 2009). Additionally, the Bureau of Labor Statistics projects a 15% growth in planning jobs between 2006 and 2016. The salary and benefits of regional and urban planners is very attractive. The Bureau of Labor Statistics indicates that the median yearly pay for urban and regional planners was $63,040 in May 2010 (Bureau of Labor Statistics, 2013). Based on the fact that the planning industry has experienced growth in the past years, the prospect of career development is also looking good. This growth is stimulated by environmental concerns and population growth being experienced. Other than becoming an urban planner, I would prefer to become an architect. Since my childhood, I have alwa ys been fascinated with the science and art of building and construction. The prospect of becoming a renowned architect is exciting and interesting because this career path will enable me to design an entire built environment- from how a building associates with its surrounding environment, to construction or architectural details that entails its interior and designing and making furniture to be used inside it. Looking at this career path from a different perspective, I established that architecture is poetic in the manner that it presents itself. It is complex in the questions and issues it gives rise to. Contrary to popular belief that architecture is static, I have established that architecture is detailed and analytical. These qualities make this career path not only attractive, but also fulfilling. A career in architecture is interesting and exciting due to its longevity nature. As compared to most professions, architects can practice their

Heteroplasmy and Response Against Azoxystrobin in Cercospora

Heteroplasmy and Response Against Azoxystrobin in Cercospora Introduction The quinone outside inhibitor (QoI) or Strobilurin is one of the most important fungicides used to control fungal and some Oomycetes pathogens in agricultural crops. This class of fungicide was first isolated from a wood-rotting fungus called Strobilurus tenacellus. Several chemically modified derivatives of natural fungicide, Strobilurin A, are available which are more stable, efficacious, less harmful to human and environment. These fungicides are commercially available with different names and active ingredients: azoxystrobin (Syngenta), fenamidone (Bayer), fluoxastrobin (Arysta), kresoxim methyl (Cheminova), pyraclostrobin (BASF) and trifloxystrobin (Bayer) (Bartlett et al., 2002; Vincelli, 2012). QoI fungicides exhibit both translaminar (across leaf blade) and weak systemic movement within the plant. All QoI fungicides have the same mode of action which disrupt mitochondrial respiration and prevent energy production inside fungal cells (Vincelli 2012). The disruption of ATP generation occurs because of binding of strobilurin at Qo site of cytochrome b hence preventing electron transport from cytochrome b to cytochrome c1 (Bartlett et al., 2002). QoI fungicides are applied to control a broad range of plant pathogens including fungi, water molds, downy mildews, powdery mildews and rusts (Vincelli, 2012). They are mainly used as protective and curative fungicides because of effective action against spore germination and penetration (Balba, 2007). The eradicative property has also been reported by preventing sporulation of fungal pathogen (Anesiadis et al., 2003). More than 50 species of plant pathogens resistant to QoI fungicides has been reported and there is a high risk of selecting resistant isolates in the field (Fungicide Resistant Action Committee, 2013). Three different point mutation in mitochondrial cytochrome b gene has been associated with resistant mechanism against QoI fungicide. The primary mechanism of resistance is by amino acid substitution from glycine to alanine at 143rd codon (G143A) (Bartlett et al., 2002). Other two point mutation at cytochrome b gene is the substitution of phenylalanine with leucine at po sition 129 (F129L) and glycine with arginine at position 137 (G137R) which confer QoI resistance (Fernà ¡ndez-Ortuà ±o et al. 2010). Another mechanism has also been identified that can bypass the blockage of electron transfer. Alternative oxidase (AOX) is a strobilurin-insensitive terminal oxidase which can bypass electron transfer in Complex III and Salicylhydroxamic acid (SHAM) is an active inhibitor of AOX (Wood and Hollomon, 2003). Resistant mechanism of C. sojina against QoI fungicides is associated with a mitochondrial genome which is present in multiple copies within a single cell. The coexistence of wild and mutated alleles in QoI resistant/sensitive locus has been reported in several other fungal pathogens such as Corynespora cassiicola, Collectotrichumgloeosporioides, Venturia inequalis and Mycovellosiella nattrassii (Ishii et al., 2007; Villani and Cox, 2014). The proportion of wild and mutant allele in the mitochondrial genome has a major role for quantitative resistance (Villani and Cox, 2014). Protective efficacy of the full dose of azoxystrobin against powdery and downy mildew has been found to decrease as populations contained 10% resistant isolates (Ishii et al., 2007). There have been reports of loss of resistance stability in the absence of selection pressure and vice versa (Fraaije et al., 2002; Ishii et al., 2007). The main objectives of this study are to i) identify heteroplasmy in Cercospora sojina; ii) monitor the proportion of resistant and sensitive allele in the presence of selection pressure in the laboratory; and, iii) study the sensitivity of C. sojina against azoxystrobin. Materials and Methods Isolate selection and development of single spore cultures Isolates of C. sojina were screened for resistant and sensitive allele using Taqman assay. After screening, three isolates each having resistant and sensitive alleles were chosen for single spore cultures. Isolates were transferred to V8-RA media and grown in dark cabinet to enhance sporulation. After three weeks, plated were flooded with water and filtered with muslin filter cloth. Water was observed under dissecting microscope to identify single spores. Sterilized needed were used to pick single spore and transferred to new V8-RA plates. Culture was left at room temperature, mycelium harvested, lyophilized and DNA was extracted. Radial growth study A total of two isolates: 158-1 (resistant) and 312-1 (sensitive) were selected for fungicide sensitivity and radial growth study. Four different concentrations of azoxystrobin including control were used to culture both isolates in two replications. Technical grade formulation of azoxystrobin (0.104 gm) (96% a.i.; Syngenta Crop Protection) was used to make 100,000  µg a.i./ml stock in 1 ml acetone. Serial dilution was done to make four different concentration stocks: 10,000, 1000, 100 and 100  µg a.i./ml. V8 media was prepared with four different concentrations (10, 1, 0.1, 0.01  µg a.i./ml) by adding 1ml of respective fungicide stock in 1 liter of media. All four media along with control was amended with salicylhydroxamic acid (SHAM) at 60  µg a.i./ml. Two straight line at 90o were drawn at the center of the plate. For resistant and sensitive isolates, a 5 mm mycelium disc was taken and placed at the center of amended plates in two replications. For each plate, diameters of growth were measured at the interval of 11, 21 and 30 days. Mycelium disc from amended plates was again transferred to the newly amended plate after 10 days. Diameters were measured similarly for three generations. Taqman assay and Sanger sequencing The G/C point mutation in cytochrome b gene will be discriminated by Taqman assay consisting of two dyes. VIC can detect resistant allele C and FAM can detect sensitive allele G. Threshold cycle or Ct of two dyes will be used in detecting the presence of two alleles in a single spore culture. Ct value is the cycle number at which the fluorescence generated crosses the threshold fluorescence and is inversely proportional to the amount of nucleic acid. Lower Ct indicates higher copies in the sample. Sanger sequencing will be done to confirm the presence of both alleles in a single spore. Two primers pairs (Forward: 5 CTCATTAAATTAGTAATAACTGTGGC 3 and Reverse: 5 TAATACAGCTTCAGCATTTTTCTTCT 3 ) will be used to amplify a part of cytochrome b gene. PCR reaction will be done in a total volume of 25  µl consisting of 1.25  µl (10  µM) of each primer, 12.5  µl of 2x Veriseq PCR mix (Enzymatics Inc.), 1.25  µl DNA and 8.5  µl water and run in following settings: initial denaturation at 94 ° C for 2 min followed by 29 cycles of denaturation at 94 ° C for 20 s, annealing at 55 ° C for 25 s, extension at 72 ° C for 1 min and final extension at 72 ° C for 10 min. Data analysis Sequences derived from Sanger sequencing will be aligned to publicly available cytochrome b gene of C. sojina. The QoI resistant/sensitive point mutation locus will be observed for Heterozygosity. The proportions of resistant and sensitive alleles will be calculated based on Ct values and statistical analysis will be performed to compare among different generations. The percent growth inhibition will be calculated as: ([colony diameter on control media 5 mm] [colony diameter on fungicide amended media 5 mm]) / ([colony diameter on control media 5 mm]) x 100. Further, radial growth of the same isolate among three generations and four different treatments will be compared statistically. Expected results This study will help to explore if heteroplasmy exists in C. sojina as in other Cercospora species. The proportion of resistant and sensitive isolates determines the extent of disease, so it is important to know this ratio. In vitro assay to check the sensitivity of isolates against azoxystrobin at different concentration in a different generation will help to understand the effect of selection pressure. Further measurement of resistant and sensitive proportion with qPCR would help to determine the change occurred in following generations. Genetic study after fungicide treatment will also contribute in identifying changes due to selection pressure. References Anesiadis T, Karaoglanidis G and Tzavellaà ¢Ã¢â€š ¬Ã‚ Klonari K. 2003.

United States Involvement in The Second World War (WWII) Essay

World War II   Ã‚  Ã‚  Ã‚  Ã‚  As totalitarian sates emerged into power, the United States got involved with World War II to help control these groups and to promote democracy in the European theatre of the world. The party with the most power at the time was the Nazi Party, led by Adolf Hitler. This socialist party was led by a powerful dictator who broke away from the League of Nations and began to conquer vast amounts of territory at a fast rate. The United States wanted to leave foreign affairs alone in fear of another world war. The United States could not avoid the fact Hitler was taking over Europe and help was needed. The United States became fully involved in the European theatre of World War II when Hitler led his armies on a series of blitzkrieg’s, taking over Denmark, Norway, Belgium, Holland, northern France, and by breaking the Nazi-Soviet pact.   Ã‚  Ã‚  Ã‚  Ã‚  The United States, under the presidency of Franklin D. Roosevelt, wanted to remain neutral and wanted to stay out of foreign affairs. People like Lindbergh strongly opposed any aid to foreign affairs, but Roosevelt felt American security and Democracy was in jeopardy if no help was given. As Hitler began his campaigns in Europe, especially in Poland, the United States sent aid to France and Britain to resist the Nazi’s. Germany defeated Poland and easily took over weaker countries, sometimes without Keith 2 firing a single shot as in Czechoslovakia. The United States remained...
