Job satisfaction and job performance: is the relationship spurious?Cook, Allison Laura 15 May 2009 (has links)
The link between job satisfaction and job performance is one of the most studied
relationships in industrial/organizational psychology. Meta-analysis (Judge, Thoresen,
Bono, & Patton, 2001) has estimated the magnitude of this relationship to be ρ = .30.
With many potential causal models that explain this correlation, one possibility is that
the satisfaction-performance relationship is actually spurious, meaning that the
correlation is due to common causes of both constructs. Drawing upon personality
theory and the job characteristics model, this study presents a meta-analytic estimate of
the population-level relationship between job satisfaction and job performance,
controlling for commonly studied predictors of both. Common causes in this study
include personality trait Conscientiousness, Extraversion, Agreeableness, and core selfevaluations,
along with cognitive ability and job complexity. Structural equation
modeling of the meta-analytic correlation matrix suggests a residual correlation of .16
between job satisfaction and performance—roughly half the magnitude of the zero-order
correlation. Following the test of spuriousness, I then propose and find support for an
integrated theoretical model in which job complexity and job satisfaction serve as
mediators for the effects of personality and ability on work outcomes. Results from this model suggest that job complexity is negatively related to satisfaction and performance,
once ability and personality are controlled. Contributions of this paper include
estimating the extent to which the satisfaction-performance relationship is partly
spurious, which is an advancement because the attitude-behavior link has not been
estimated in light of personality and job characteristics. Another contribution is the
integrated theoretical model, which illuminates mediators in some of the effects of
personality and ability.

Toward an understanding of when and why situational constraints influence performanceHorner, Margaret Tutt 15 May 2009 (has links)
The current study sought to explain when and why situational constraints
negatively influence performance on a complex task. In particular, perceived control
and affective reactions (frustration and satisfaction) were examined as potential
explanatory mechanisms, while ability and motivation were tested as moderators. The
influence of situational constraints on task strategies was also examined and tested for
possible nonlinearity. Finally the extent to which task strategy use moderates the
situational constraint-task performance relationship was investigated. A laboratory
study using 158 undergraduate psychology students was conducted. Three levels of
situational constraints (low, moderate, high) were experimentally manipulated.
Performance on a problem solving execution task, as well as experimenter observations
of strategy use, were used to represent the constructs of interest in the study. Results
indicated that situational constraints were directly related to task satisfaction and
frustration and performance. In addition task strategy use was directly related to
performance. However, there was no evidence for mediation or moderation effects.
Limitations and future directions are discussed.

Development of new methodologies for evaluating the energy performance of new commercial buildingsSong, Suwon 02 June 2009 (has links)
The concept of Measurement and Verification (M&V) of a new building continues to become
more important because efficient design alone is often not sufficient to deliver an efficient building.
Simulation models that are calibrated to measured data can be used to evaluate the energy performance of
new buildings if they are compared to energy baselines such as similar buildings, energy codes, and design
standards. Unfortunately, there is a lack of detailed M&V methods and analysis methods to measure
energy savings from new buildings that would have hypothetical energy baselines. Therefore, this study
developed and demonstrated several new methodologies for evaluating the energy performance of new
commercial buildings using a case-study building in Austin, Texas.
First, three new M&V methods were developed to enhance the previous generic M&V
framework for new buildings, including: 1) The development of a method to synthesize weathernormalized
cooling energy use from a correlation of Motor Control Center (MCC) electricity use when
chilled water use is unavailable, 2) The development of an improved method to analyze measured solar
transmittance against incidence angle for sample glazing using different solar sensor types, including
Eppley PSP and Li-Cor sensors, and 3) The development of an improved method to analyze chiller
efficiency and operation at part-load conditions.
Second, three new calibration methods were developed and analyzed, including: 1) A new
percentile analysis added to the previous signature method for use with a DOE-2 calibration, 2) A new analysis to account for undocumented exhaust air in DOE-2 calibration, and 3) An analysis of the impact
of synthesized direct normal solar radiation using the Erbs correlation on DOE-2 simulation.
Third, an analysis of the actual energy savings compared to three different energy baselines was
performed, including: 1) Energy Use Index (EUI) comparisons with sub-metered data, 2) New
comparisons against Standards 90.1-1989 and 90.1-2001, and 3) A new evaluation of the performance of
selected Energy Conservation Design Measures (ECDMs).
Finally, potential energy savings were also simulated from selected improvements, including:
minimum supply air flow, undocumented exhaust air, and daylighting.

Dietary Effect on the Performance and Body Composition of the Generalist Insect Jerbivore, Heliothis virescens (Lepidoptera: Noctuidae)Roeder, Karl Adam 2010 August 1900 (has links)
All animals, including insect herbivores, eat to acquire nutrients that are essential
for fueling physiological processes associated with growth, development, and
reproduction. Protein and digestible carbohydrates are two nutrients required in large
quantities by insect herbivores, but the amounts in which they occur in plants can be
highly variable. In this thesis, I explore how the amounts and ratios of protein and
digestible carbohydrate in an insect herbivore's food affect lifetime performance and
body elemental composition. I do this by confining a generalist caterpillar, Heliothis
virescens, to semi-synthetic foods with fixed protein-carbohydrate amounts and ratios.
I show that foods with protein-carbohydrate ratios that match the self-selected
protein-carbohydrate intake of final instar caterpillars correlate strongly with best
performance, and that small deviations away from this optimal protein-carbohydrate ratio
can result in large drop-offs in overall performance, particularly for males.
I also show the importance of protein-carbohydrate balance over total
macronutrient content. Finally, my results demonstrate that H. virescens caterpillars do
not practice strict elemental homeostasis. My result, when contrasted with earlier work on caterpillars, suggests that hemimetabolous and holometabolous insect herbivores practice
different degrees of elemental homeostasis.

The research of performance bonus management system by public administrations : compare administrative organizations and public schoolsChen, Su-Chen 22 June 2006 (has links)
Since 2002 Central Personnel Administration carried out the performance bonus management system at administrative departments, the opposite opinions have never died out. The most controversial point is that it is believed this system suits private enterprises more than administrative departments. For years, academic papers have focused more on comparative studies between Taiwan and other countries, or between government institute and private enterprises, but there are only few on different units within public administrative departments. Public schools, in particular, have more difficulties in enforcing and have less aspiration to enforce the system. The purposes of this study are to explore the predicaments and tentative resolutions of public schools.
This study apply literary and documents to analyze the differences between administrative departments and public schools. By doing so, the researcher explore the predicaments of public schools and propose possible resolutions to every problem. The methodology is as follows: first, introducing the enforcement process in accordance with literary documents. Second, comparing administrative departments with public schools in the aspects of objectives, organizations and suitable subjects, and the differences would be further analyzed. Third, offering tentative resolutions to the difficulties that public schools should face.
The conclusion of this study could substantiate the enforcement of the performance bonus management system. Those who involved in the system execute it authentically would help life up the effectiveness of administration and the quality of teaching in public schools. Moreover, till now only administrative departments care about the practical effects of the performance bonus management system, no one notices the difficulties of public schools. This study could be helpful to arouse the interests of public schools to enforce the system, and also to propose useful strategies for other schools as references.

The Rebuild Plan of A General Measure of Public- and Private Sector Employee PerformanceTsai, Ya-Chu 07 July 2006 (has links)
Work performance researches in the past ten years have been numerously conducted in Taiwan. Most of researchers use International benchmarking performance measurement with or without modifications. . Only few develop their own measurement based on the needs of Taiwan business organizations. My project focuses on the rebuild of performance evaluation program in the light of the employees in Taiwan enterprises considering the national conditions, culture, credibility and efficiency.
This paper has studied the theories of Campbell(1990) and Borman & Motowidlo(1993) and developed a job performance evaluation form suitable for employees in Taiwan. A total number of 3000 copies of survey questionnaires were sent out. Out of this, 2779 were returned, representing a remarkable return rate of 92.63%. My performance evaluation matrix presents as below:
1. Task performance: Task performance involves official responsibility or the proficient of "technical core" of the activities in formal jobs and duties. Including 9 items.
2. Contextual performance: Contextual performance involves activities maintaining the environment that needs to exist to allow the technical core to operate. Contextual performance are activities such as: " Helping and cooperating with others. Following organizational rules and procedures even when personally inconvenient. Endorsing, supporting and defending organizational objectives." Including 9 items.
3. Job Positive: Job Positive involves measurement of positive personality, attitude and psychological environment of jobs and duties. Job Positive are activities such as: "Volunteering to carry out task activities that are not formally part of the job. Looking for a challenging assignment. Tackling a difficult work assignment enthusiastically and Voluntarily doing more than the job requires to help others or contribute to unit effectiveness." Including 4 items.
Key words: Job Performance, Taiwan, Employee.

The research of marketing strategy and recruit performance ¢w a case as private schools in Kaohsiung cityLan, I-Pin 03 August 2006 (has links)
Faced with the pressure of competition and reformation of education in public schools, private schools facing difficult plight in recruit students, although they have different reasons, most private schools use poor marketing strategy to enhance the competitiveness of the schools are indisputable fact. This paper takes a case as private schools in Kaohsiung city to discuss the relativity of schools marketing strategy and recruit performance and offer some references for the research of private schools layout in future.
The research of this paper is focused on the problems of private schools marketing; because of the occupational schools have lots of sections, so the selection of samples use the fashion of conception, this paper selected the teachers, students and paterfamilias as the objects of this research. This paper studies a total of 1800 questionnaires were issued, recovering valid questionnaires 817 shares and the rate of return was 45.39%, thereinto, students questionnaires were 600 shares, 457 shares valid questionnaires were recovered and the rate of return was 76.17%, paterfamilias questionnaire were 600 shares, 157 shares valid questionnaires were recovered and the rate of return was 26.17%, teachers questionnaire were 600 shares , 203 shares valid questionnaires were recovered and the rate of return was 33.83%.
Based on the research, this paper got some conclusions, the conclusions following are:
(1)The mixed strategies of marketing of this research are the important lay in the marketing of private schools;
(2) According to this study found that the various marketing strategies has its main marketing projects;
(3) "Access planning" is the most important content projects of the status of private schools marketing attitude, "equipment strategy" is the most important projects of the cognitive degree of private schools marketing strategies;
(4) Through the analysis of questionnaires of teachers, students and paterfamilias, it knows that the vast majority of teachers¡¦ score higher than parents and students, it means the teachers on the status of the marketing approach for the best;
(5) Different identity variables exists significant differences in different lays;
(6)The study finds students more attractive marketing attitudes, school enrolment more effective performance, paterfamilias marketing attitude better, the marketing strategy for schools to focus on the image of the strategy, teachers marketing attitude more better, more awareness for schools¡¦ marketing.
