Investigation of police officer selection procedures

Provines, Jessica Lynn 12 1900 (has links)
In the current dissertation, the relationship between police officer selection procedures and officer performance during the first year of employment was investigated within a metropolitan law enforcement agency. Ninety-two officers were followed during their first year of employment including the hiring process, academy and field training, and yearly evaluations. Data on education, aptitude, physical agility, personality, academy performance, supervisor ratings, and terminations were collected. The results reveal that the psychologists' recommendations predict whether or not an individual will leave the department before the completion of their first year as an officer. In addition, the aptitude test administered by the municipal human resources department accounted for the most variance in academy scores. Weak predictions were demonstrated for field training ratings and yearly evaluations. / Thesis (Ph.D.)--Wichita State University, College of College of Liberal Arts and Sciences, Dept. of Psychology. / "December 2006." / Includes bibliographic references (leaves 72-77)

The effects of non-musical components on the ratings of performance quality /

Siddell-Strebel, Jeanne. January 2007 (has links)
The purpose of this study was to determine whether certain non-musical components of a performance affect evaluator's performance quality ratings. Specifically, if there is an age at which point the presence of a music stand (i.e. an implied use of the score), the performers attractiveness, attire, stage behaviour and perceived level of accomplishment impacts performance ratings. Fourteen cellists were videotaped performing by memory, and then a second time with their music on a music stand, synchronizing their motions with the audio feedback from their first performance. The cellists and their performances were evaluated by 1024 individuals with no formal training in music ranging in age from six to fifty-five years old. Each evaluator was assigned to one of six groups: Visual only, Audio only, Memorized, Dubbed, Random 1, or Random 2. Results revealed that the presence or absence of a music stand had no impact on performance ratings. Performer attractiveness affected performance ratings for both sexes, although contrary to previous findings, being attractive was not advantageous. Dress had an inverse effect on ratings of female performers and poor stage behaviour affected ratings of both sexes. Although evaluators were unable to predict a performer's proficiency based solely on gesture, proficiency gestures made by musicians during performances affected ratings. Evaluators in the audiovisual conditions gave performers who appeared less accomplished significantly lower ratings than those in the audio only condition. Evaluators aged 13 were more critical than younger evaluators with their musical ratings and their ratings were also affected by the visual aspects of a performance. These results suggest that older non-musician evaluators use visual aspects to help their evaluations of subjective musical elements because they have a hard time hearing differences.

Employees' perception of the effective use of the performance appraisal system in a financial institution.

24 April 2008 (has links)
Although performance appraisals exist in most organisations, they are not implemented correctly. In many organisations the link between the performance appraisal ratings and the outcome is not so obvious. This has led to mistrust of the performance appraisal process by the users and the total process does not command the credibility it deserves. A summary of problems with performance appraisals systems and processes are as follows: Preparations prior to appraisal with staff are not adequate. Users of the system are not formally trained. Performance appraisal processes are often considered to be unpleasant and time consuming. The performance appraisal processes are subject to subjectivity. The rating scales and performance dimensions used in the systems are open to different interpretations due to lack of clear guidelines. / Prof. W. Backer

A case study of operational performance of a build-operate-transfer municipal waste incinerator in Luchao, Chiayi County

Chang, Ming-jer 03 September 2004 (has links)
Abstract Over the last decade, business and industry in Taiwan have been growing rapidly, but increasing amount of the wastes has relatively been created by people for various reasons. Thus, with the rapid growth of the wastes and the snowballing difficulty of getting place for landfill, incineration without doubt has become the way that wears best to solve such annoyed problem. Furthermore, the issue of waste disposal is now the most important problem to cope with for our government. Owing to the shortage of budget, our government allowed the private sectors to invest in the BOT projects of incinerator to meet and satisfy the growing needs of handling the increasing amount of garbage. According to the result of our research, the BOT projects operated by private companies are very successful, and receive positive responses in terms of reducing the expenses and costs, compared to our government¡¦s factories. It would be a new direction or choice in waste disposal, and would be create much profit for people and government. Keyword¡GBOT¡Boperate model¡Bperformance evaluation

On the Performance of Fast Context Switch for MinixARM

Lin, Cheng-chi 14 January 2009 (has links)
The methods of improving the cache performance are multiform and advanced of nowadays. We are concerned about the cache and TLB utility. To reduce the context switch cost on system, we utilize an address-space switching hardware of ARMS3C2410 processor to realize the fast address switching mechanism. The Fast Context Switch can help to improve cache and TLB utility and performance. Fast Context Switch is a method that can help to improve the cache performance. The key feature of Fast Context Switch is without any cache and TLB flush on process context switching. To implement Fast Context Switch, we address the different processes to different address space by process ID. When context switch occurs, we can just change the working space without the cache and TLB flush. This thesis emphasizes on the performance measure for improvement on the cache and TLB. We use a high dependable microkernel architecture for message passing between processes, this microkernel called MinixARM. Rely on the microkernel, we can more easily understand and analyze the system performance and additional cost of the cache scheme. We provide more complete performance tests by benchmarks, fast context switch can increase the system performance about 65% at most.

An evaluation of the value of security in the international marine supply chain

Loke, Wai Leng 05 1900 (has links)
Since the events of 9/11, there has been tremendous amount of renewed interests in the study of trade security. There has been an influx of security regulations and the private sector has been trying to keep pace in complying with them. However, due to the public externalities of security improvements and the lack of quantified and proven benefits, the private sector is struggling to establish business cases for their security initiatives. There is very little quantitative research in this area. Using exploratory factor analysis (EFA) and structural equation modeling (SEM), this study serves to fill this gap by introducing a statistical way of analysing and understanding the complex relationships amongst security effort, its motivators and performance and traditional supply chain performance (SCP). This study also proposes an evaluation framework for security efforts. EFA results show that security is a dimension of SCP. This means that organizations have all along been measuring an aspect of their operations that relates to security. As such, organizations should not perceive the current heightened interests in security as throwing them off-balance. In evaluating security efforts, organizations should select key performance indicators (KPIs) that represent each of the four areas of information, cargo, people and cost. SEM results show that organizations undertake security efforts as a result of both perceived security benefits and perceived collateral benefits, with perceived security benefits carrying a greater weight in the decision-making process. Results also show that organizations are implementing security initiatives out-of-compliance i.e. implementing initiatives that they perceive as not having significant impacts on security and SCP. In view of the positive relationships among perceived security impact, security effort and security performance, there is further imperative for an objective method for evaluating security efforts to prevent effort justification behaviour in determining the effectiveness of the same. Results also show that organizations perceive an improved performance in security leads to an overall improvement in SCP. However, as with other supply chain strategies, there are tradeoffs and not all aspects of SCP are impacted in the same way. Time, responsiveness and efficiency for instance are negatively impacted while reliability is positively impacted.
