This paper investigated the suggestion that situational judgment is a multidimensional evaluation methodology that assesses task and/or contextual job knowledge, and in any given situational judgment test (SJT), there may be items that better tap contextual knowledge while other items may better tap task knowledge. 233 undergraduate students completed questionnaires containing a situational judgment test, personality questionnaire, and cognitive ability test. Results supported the hypothesis that suggested personality significantly predicts contextual knowledge over and above cognitive ability, but did not support the prediction that cognitive ability significantly predicts task knowledge above and beyond personality. Preliminary results suggest that the lack of support for H2 may be due to the SJT utilized in this study, which appears to have tapped primarily contextual knowledge domains. Implications and directions for future research are suggested. / Master of Science

Prior research has attempted to develop a model of organizational citizenship behaviors (OCB) and counterproductive work behaviors (CWB), but limited testing remains a problem. The purpose of the current study is to examine OCB and CWB from a job stressor-strain approach. The sample consisted of 235 employees throughout the United States and their supervisors. Results of the study suggested OCB and CWB are affected by stressors (including interpersonal conflict, low interactional justice, job demands, and organizational constraints). Additionally, trait emotion and attributional styles affect the amount of stressors perceived. The implications as well as limitations of the study are discussed.

Abstract Due to personal experience, I¡¦m interested in the impact of the leading style on the employees. When I was reading related research, I found that the leading style didn¡¦t show positive correlation on job performance when using the relation-oriented and job-oriented as the independent variable. Modern research support transactional leadership and transformational leadership. Therefore I took leading style as the independent variable, job performance as the dependent variable and the moderating variable is psychological contract. Descriptive statistics, reliability, factor-analysis, Pearson correlation and regression were chosen for data analysis and hypothesis testing. The result is shown as the following: 1. Transactional leadership and transformational leadership have positive impact on job performance. 1.1 Transactional leadership and transformational leadership have positive correlation impact and significant impact on task performance. 1.2 Transformational leadership has positive correlation impact and significant impact on contextual performance. 2. Psychological contract has different impact on job performance. 2.1 On task performance 2.1.1 Balanced contract has positive correlation impact and significant impact on task performance. 2.1.2 Relational contract has positive correlation impact and no significant impact on task performance. 2.1.3 Transactional contract has negative correlation impact and no significant impact on task performance. 2.2 On contextual impact 2.2.1 Balanced contract has positive correlation impact and significant impact on task performance. 2.2.2 Relational contract has positive correlation impact and no significant impact on task performance. 2.2.3 Transactional contract has negative correlation impact and no significant impact on task performance. 3.Psychological contract has positive correlation with leading style and job performance. 3.1Relational contract has negative moderating effect between transformational leadership and task performance. 3.2 Relational contract has negative moderating effect between transformational leadership and contextual performance.

Purpose: The purpose of this study was to examine the relationship between job satisfaction among hotel employees as well as the relationship between employee empowerment and contextual performance behaviours. Background: Most managers and scholars emphasize that an organization’s most important tool for gaining a competitive advantage is its people and; in order for the firm to attain success employees must be involved and active. It has been argued that success within the hotel industry lies with customer satisfaction, of which is the result of overall job satisfaction of the employee. Most hotels strive to empower their employees in order to deliver better quality service. In addition, contextual performance behaviours are also common practice in such places where employees have a broad range of duties and tasks. Both empowerment and contextual performance behaviours are thus seen to provide overall job satisfaction. Method: The research approach used was that of a single case study, using a survey instrument to collect data on facets empowerment and contextual performance behaviours. The Scandic Hotels of Jonkoping were used for this purpose. The data collected were then analysed by way of factor analysis and multiple regression methods to validate the hypotheses formed in the theoretical framework. Findings and Conclusions: Based on the results of the analysis, the majority of the hypotheses were supported.  Training and rewards showed a significant relationship with overall job satisfaction. Job dedication behaviours also showed similar results. In addition, information sharing and trust and training and rewards proved to have interrelationships as facets of empowerment.  Interpersonal facilitation and job dedication behaviours were also proved to be distinct behaviours within contextual performance.

This research examines the role played by an employee¡¦s supervisor and organization in the relationship between the support perceived by an employee and his or her affective commitment, task performance, and contextual performance to the organization. Our analyses, based on data taken from a sample of 222 steel manufacturing firm employees in Taiwan, reveal that there is a significant relationship between perceived organizational support and affective commitment, whereas nonsignificant relationship are found between perceived organizational support and task performance, also between perceived organizational support and contextual performance. Our results also highlight the moderate effect of perceived supervisor support in the relationship between perceived organizational support and employee¡¦s task performance, and contextual performance.

Social networks and social capital issues have been combined with organizational behavior scope for decades. Nevertheless, the difficulty of methodology and data collection causes the rareness of related empirical study. In this dissertation, multi-level research structure and hypothesis, including dyadic-level, individual-level, and network-level, are proposed to be examined respectively. 505 questionnaires were collected from 17 companies providing a great deal of support to be analyzed by social network analysis technique of UCINET VI for windows. The following are results and conclusions of each research level: For dyadic level, ¡§cognition-based trust¡¨ and ¡§affect-based trust¡¨ are core variables representing dyadic relationship quality. Similarity/attraction paradigm, self-categorizing, and social identity were used as theory basis to prove the positive effects of antecedents embracing gender, education level, age, and tenure similarity, also the ¡§value fit¡¨ and ¡§cognitive friendship¡¨, on dyadic relationship quality and interaction behaviors. The results demonstrate the higher similarity of education level and tenure between two individuals, the greater level of value fit, friendships, cognitive-based trust, affect-based trust, knowledge sharing, and citizenship behaviors. Cognition and affect trusts between two individuals cause the knowledge sharing and citizenship behaviors for each other. The positive effects of gender differences on relationship quality are discovered unexpectedly. For individual level, the normalized in-degree of centralities of ¡§advice networks¡¨ and ¡§friendship networks¡¨ were measured by social network analysis techniques to be examined as core variables. I draw on the formal organization structure (work flow network centrality and rank), personalities (conscientiousness, high-low self-monitoring, extraversion/introversion, collectivism/individualism), and job characteristics (job inter-dependency and work loading) for the antecedent variables of ¡§advice networks¡¨, ¡§friendship networks¡¨, and personal contextual performance (knowledge sharing and citizenship behaviors). Also treat the ¡§personal social capital¡¨ as the mediate variables among personal social networks and personal contextual performance. The results demonstrate the positive effects of rank, work flow network centrality, conscientiousness, self-monitoring, collectivism, and job inter-dependency on the centrality of advice network. The negative-effects of work loading are also verified. For the centrality of friendship network, the results proved the positive effects of the work flow network centrality, and conscientiousness, also the negative effects of work loading on it. Knowledge sharing behaviors representing the part of personal contextual performance are positively affected by conscientiousness, self-monitoring, rank, work flow network centrality, advice network centrality, friendship network centrality, and personal social capital. Work loading influences the knowledge sharing behaviors negatively. Citizenship behaviors that also represent the part of personal contextual performance are influenced by advice network centrality, friendship network centrality, and personal social capital. The mediating effects of social capital among personal social networks and personal contextual performance are also manifested. For network level, the comparisons among formal organization structure and nine intra-organizational social networks demonstrate the influences of rank and division on social network structural configuration. I also draw on the similarity-attraction paradigm as the theory basis to examine the positive effects of the similarity of department, gender, age, education-level, marriage status, and nine intra-organizational social network matrices on the relational matrices of friendship and affect-trust. MRQAP (Multiple Regression Quadratic Assignment Procedure) technique is applied on this analysis. The results verified the positive effects of the similarity of department, gender, and marriage status on friendship and affect-trust between two individuals. In addition, the theoretical and managerial implications, limitations and future research questions based on the findings and suggestions for future research are provided.

Manager¡¦s managerial effectiveness is measured by how successfully he/she influences others. Leaders exert influence tactics to achieve task objective and organizational long-term objectives in a complex environment in order to maximize their job performance. By means of influence tactics, managers exert political behavior over others to achieve their organizational power settings. Thus, the purpose of the study is to understand the relationship between downward influence tactics and job performance. Results showed as following: 1. Male managers use more rationality influence tactic than that of females; female manager¡¦s contextual performance is better than that of males. 2. Managers with age between 30-39 use rationality influence tactic more than those of age 50 and above; managers with age below 30 use network and counteract influence tactics more than those of other age groups; task performance and contextual performance of managers with age over 50 are better than other age groups 3. Single managers use counteract influence tactic more than married managers; task performance and contextual performance of single managers are better than those of married managers 4. Managers with Master/Doctoral degrees use rationality, network, exchange, pressure, and counteract influence tactics more than those of other educational backgrounds. 5. Managers with 1 ~ 3 years working experiences use rationality and counteract influence tactics more than those of other years of working experiences; managers with working experiences over 10 years use network and pressure more than those of other years of working experiences. 6. High-level managers use rationality and pressure influence tactics more than those of other lower level managers; project-based managers use network and counteract influence tactics more than those of other levels of managers. 7. Middle-level managers have higher task performance than that of other levels of managers; high-level managers have higher contextual performance than that of other levels of managers. 8. After using gender, age, martial status, educational background, working experience and job level as control variables, and compare the relationship between downward influence tactics and job performance, we found: 8.1 Managers who are male, age over 35, single, college and below educational background, middle/high level, 5 years and above working experiences, the more rationality influence tactic they use, the better their job performance are. 8.2 Managers who are university and above, have 5 years and above working experiences, the more exchange influence tactic they use, the better their job performance are. 8.3 Managers who have less than 5 years of working experiences, the more pressure influence tactic they use, the better their task performance are. 8.4 Managers who are male, 35 years and above, single, university and below, and middle/high level, the more exchange influence tactic they use, the better their contextual performance they are.

This search was conducted to focus on the relationship between the type of Taiwanese managers¡¦ politics of downward influence and job performance, with responsible individual correlation, and to influence job performance. The search method this study used was group segmentations. After empirical analysis, we found out: 1. By using K-means ¡§Cluster analysis¡¨, we got three different types of Taiwanese manager¡¦s politics of downward influence. We named them by their downward influence politics and strategies as follows: 1-1 Controlling & Counteracting. 1-2 Reciprocal Networking. 1-3 Exerting Pressure. 2. The relationship between individual variable and the type of politics of downward influence are below: 2-1 Manager to the type of politics of downward influence with gender, age and martial status has no significantly effect. 2-2 Manager to the type of politics of downward influence with the education background, working experience and job level has significantly effect. 3. The relationship between the type of Taiwanese managers¡¦ politics of downward influence and job performance are below. 3-1 Manager of the ¡§Reciprocal Networking¡¨ has better contextual performance than ¡§Controlling & Counteracting¡¨. However, manager of the ¡§Exerting Pressure ¡§doesn¡¦t reveal the difference with the contextual performance. 3-2 Manager of the ¡§Exerting Pressure¡¨ has better task performance than ¡§Controlling & Counteracting¡¨. However, manager of the¡¨ Reciprocal Networking¡¨ doesn¡¦t reveal the difference with the task performance. 3-3 Manager of the¡¨ Reciprocal Networking¡¨ has better job performance than the ¡§Controlling & Counteracting¡¨. Manager of the ¡§Exerting Pressure¡¨ has better job performance than ¡§Controlling & Counteracting¡¨.

Many economists in 21th century agree that the ¡§Research ¡® Development¡¨ is an essential factor to the ling-term competitiveness and the living quality of the civilians of a country. Michael E. Porter indicates in his book, ¡§The Edge Of Nation Competitiveness¡¨, in the competitive world, the creating and exerting the new knowledge are more important than using the traditional economic edges- natural sources and capital. R ¡® D is an accumulation and innovation of knowledge, and a foundation of the technology progress and economic growth. Therefore, the enterprises worldwide emphasize more on the management of the researchers. In this area, the ¡§work redesign¡¨ gets much spotlight. The enrichment of work was designed to cope with the characteristic of research, uncertainty and complexity, and to help employees performing completely. It also helps researchers to require more self-esteem. However, as the technology developed, the work contents are different than used to be. Does the Job Characteristic Model (JCM) of the Hakman and Oldman still fit the work variety? This is an issue that a manager should pay much attention while doing work redesign. By doing documents study, this research points out that the work redesign influences the job performance and is various with the work content. There are many factors affecting the work design and work performance, such as individual character, personal trait, work satisfaction, contextual satisfaction and growth need strength. This research is focusing on the relationship between job characteristic and work performance by evaluating the individual requirement (growth need strength and contextual satisfaction). Through real case investigation, there are some results in this research. 1.The task significance is unrelated to the contextual performance; however, besides that, each factor in this research is related to another one. The higher task identity and autonomy are, the higher task performance will be. The feedback from the job itself has the significant influence on contextual performance. 2.The individual character has different influence on each factor in this research. The researcher, who receives higher education has higher contextual satisfaction and higher job performance. Besides the education, the other factors, for example, the gender, marriage and age have little influence on the contextual satisfaction and job performance. 3.The contextual satisfaction and growth need strength have the moderating effects on the relationship between job characteristic and has job performance. On the contrary, the context satisfaction has no the moderating effects on the task identity and job performance of the job characteristic. The growth need strength has the moderating effects on the relationship between production responsibility and job performance, so as on the method control and task performance. But for public organization, it has the moderating effects on the relationship between task significance and job performance as well as on the production responsibility and task performance. In the high-tech company, the moderating effects between growth need strength and task variety as well as the moderating effects between growth need strength and task identity have the influence on task performance and contextual performance. 4.Whether Hackman and Oldman job characteristic model or Jackson et al. job characteristic model has little difference in analyzing the job performance, in public organization. However, analyzing the job performance of researchers in high-tech company, using Jackson et al. job characteristic model has better result
