Paraphrase and improve presenting style - Essay Example The sources of these sounds are categorized in relation to their engagement of the basis of molecular formation; solids, liquids and gasses. Background: In terms of pitch and frequency discrimination tasks, human performance has been intensively researched with its primary focus upon the duration of repetitive wavecycles. These studies concluded that an individuals’ increasing exposure to wavecycles subsequently increases their performance. This revelation would contribute to the understanding of the evolution of animal’s communicative sounds, particularly from single-pulse resonances which became repetitive expressions of the same stimulus. A study conducted by Hsieh and Saberi (2007) found that an increase in performance coincided with the lengths of exposure duration, where increasing exposure increased performance. Aim: The primary aim of this study was to explore the effect repetition has upon human performance, particularly how the number of exposure periods to a damped sinusoid and double damped sinusoids increases the individuals’ performances. The experimenter then compared the effect on individuals’ performances, focusing between damped and double damped sinusoids. Method: Ten participants with average auditory abilities were recruited from a single population; the staff and students of the university. The experimenters exposed the subjects to an increasing number of periods (1, 2, 4, 8 and 16) of a damped and double damped sinusoid. They accomplished this by using â€Å"a three alternative forced choice method and a one up three down adaptive procedure stair case† in conjunction with the examination of the Just Noticeable Difference threshold in the subject’s ability to discriminate the exposure to varying frequencies. The experimenters labeled the samples in this study as â€Å"looks†, as their multiple-look models would collectively account for the collected data which came from the temporal

Globalization and chronic poverty and health Essay

Globalization and chronic poverty and health - Essay Example ement of people and resources thus results into child labor, loss of middle class jobs, capitalism, destruction of environment, and obliteration of indigenous cultures thereby leading to increased inequality (Milanovic, 667). In this respect, the poor continue to remain poor while the rich continue to accumulate wealth. Persistent inequality results into a vicious cycle of poverty in which the poor cannot take their children to school hence their children will not get better jobs due to increased competition in the job market and will continue with a generation of chronic poverty. Chronic poverty can be defined as a situation in which individuals are experiencing significant incapability deprivations for a longer period of time often more than five years (Hulme and Andrew, 403). Chronic poverty is closely linked to health standards. Research has shown that where there is high poverty index, the health standards are likely to be compromised. This is because individuals are not able to meet the basic nutritional, sanitation and hygienic standards. In this regard, they are left more susceptible to both communicable and non communicable diseases including nutritional deficiencies. Trends in globalization have therefore resulted into increased income inequality therefore leading to persistent chronic poverty and deteriorating health status among the poor. Forces of globalization play a key role in shaping political, economical and social policies that are adopted by governments. In the face of globalization, many poor countries do not gain from the increased interconnectedness because of increased competition hence even domestic policies in poor countries trend to favor developed countries. This inequality results into social injustice for the chronically poor population. Milanovic (669), views social justice as a matter of life and death since it affects the way people live, their consequent chance of illness and their risk of premature death. This is the reason why

Performance management Essay Example | Topics and Well Written Essays - 1500 words - 1

Performance management - Essay Example Performance management concept links the individual interests and objectives with the mission and strategic objectives of the organisation thus enabling employees to focus on the performance objectives (Aguinis 2012). Historical development of performance management Some of the earliest theorists of scientific management include Fredrick Winslow Taylor who advocated for scientific management concepts with the aim of improving the productivity of each individual employee. According to Taylor, simplification of the jobs would increase employee productivity, and enable cooperation in the organisation. Ideally, Fredrick Taylor contributed to performance management through advocating for the replacement of the ‘rule of thumb’ and replace it a scientific method that could enhance the efficiency of work in the organisation. Taylor’s second scientific management principle is geared at matching workers to their jobs depending on the job description, skills and capabilities of each individual inn the organisation. ... ocation of the work between management and workers in a manner that managers spend most of their work time while laying out strategies and training while workers perform the routine activities in an efficient manner. Taylor made a contribution to performance management through ensuring job description, task specialization and incentive schemes for the highly performing employees (Aguinis 2012). Another early theorist of performance management in organisations was Mc Gregor. He came up with improved performance appraisal methods and measures of improving organisational effectiveness. According to Mc Gregor, performance management should involve appraisals that cater for administrative needs such as salary levels and promotion opportunities, information need such as the need for feedback and suggestion and finally motivation of the workforce. McGregor challenged the original notions of Taylor since employees could not be machine parts that can be redesigned or even eliminated. He perce ived employees as individuals with unique needs thus introduced a human relations approach to performance management. According to his theory X and Y, theory X asserts that average employees dislike work and thus individuals must be coerced since they tend to avoid both work and responsibility. Some of the modern methods that have been implemented in order to encourage this category of employees perform effectively include punishments and rewards (Bacal 2011). Theory Y asserts that work is natural just like play and people will apply self-direction and control in attaining organisational objectives, thus eliminating the need of coercion and punishments. In addition, employees will accept and seek more responsibility if rewards are associated with achievement and creativity of the individual

Biochemical identification of unknown bacteria Lab Report

Biochemical identification of unknown bacteria - Lab Report Example 1) Nutrient agar slant: Given culture was streak on the nutrient agar slant and incubated at two different temperature 25Â °C and 37Â °C respectively. After 24h of incubation, slants were taken out from incubator and growth was observed. Growth on tube incubated at 37Â °C was found to be effuse and the growth was extensive while in case of tube incubated at 25Â °C growth was found to be lesser compared to previous tube and echinulated in nature. There was no pigmentation observed and growth was found to be whitish in color and translucent in nature. Results indicated that given unknown bacteria is either Escherichia coli, Enterobacter aerogenes or Staphylococcus aureus ,being human /animal inhabitant The optimum temperature for growth of these bacteria is 37Â °C (i.e. human body temperature) while in case of Pseudomonas aerogenosa being free living as well as human inhabitant, it can grow at 25Â °C as well as 37Â °C . Similarly it also produces bluish green pigment and grows as mucoid colony. 2) Nutrient agar: Given culture was streak on to the nutrient agar plate using quadrant streak technique and incubated at 37Â °C for 24 h. After incubation colonies were found to be convex, circular and having entire margin. Optically colonies were found to be translucent and without any pigmentation. This observation again ruled out the possibility of Pseudomonas aeroginosa. Similarly colony of Staphylococcus aureus is opaque, slightly elevated, appears yellowish white.
