Relationships among five forms of commitment: an empirical assessment

This paper examined whether Morrow's (1993) model of five universal forms of work commitment (affective organizational commitment, continuance organizational commitment, career commitment, job involvement and work ethic endorsement) has empirical support. The paper explored the discriminant validity among the five scales of these commitment forms. It also tested Morrow's model regarding the interrelationships among them in comparison with an alternative conceptualization proposed by Randall and Cote (1991). Two hundred and thirty‐eight nursing staff from two hospitals in western Canada were surveyed. Results of confirmatory factor analysis (LISREL VIII) and correlation analysis showed an acceptable discriminant validity among the five commitment foci. The results of path analysis (LISREL VIII) showed a poor fit with the data of Morrow's model and a better fit with the alternative model of Randall and Cote. Revised models based on the modification indices from both models were tested, and supported the Randall and Cote approach. The paper concludes with implications regarding the continuing assessment of Morrow's conceptualization to establish an acceptable definition and measurement of universal forms of work commitment.

Differentiating antecedents of organizational commitment: a test of March and Simon's model

Recent theory regarding the nature of organizational commitment suggests that viewing it as comprised of two dimensions, value commitment and continuance commitment, is of theoretical and practical value. This field study found the differential antecedents of these two commitment dimensions to be consistent with the March and Simon (1958) framework using the two-dimensional organizational commitment questionnaire from Mayer and Schoorman (1992). Organizational tenure, retirement benefits, education, and age were more highly correlated with continuance commitment, while felt participation, perceived prestige, job involvement, and role ambiguity were more highly correlated with value commitment. Analysis using LISREL 7 supported the pattern of relationships between the antecedents and the two commitment dimensions. © 1998 John Wiley & Sons, Ltd.     

A new conceptualization of union commitment: Development and test of an integrated theory

An introductory conceptual and empirical review stresses the need for a stable theoretical basis for union commitment research. The purpose of this paper is to develop a new conceptualization of union commitment based on the integration of two theories (the theory of reasoned action and the rationalistic approach to commitment). The integrated theory suggests that union commitment is composed of two dimensions, one based on instrumentality and one based on ideology, which are causally related to prounion behavioral intentions and, in turn, to union participation. Propositions derived from the integrated theory are tested using data on 1486 blue-collar workers in Sweden. Results of linear structural equation modelling with latent variables and of multiple regression analyses provide strong support for the construct validity of the commitment dimensions and the overall applicability of the integrated theory. The central findings, their conceptual implications for the understanding of union commitment, and their practical implications for unions are discussed.     

Mentorship and career mobility: An empirical investigation

The literature on mentorship is briefly reviewed, revealing that many studies have documented the functions that mentors provide to proteges, including vocational and psychosocial support. This study investigates the link between these functions and the career mobility outcomes of proteges. Results from a random sample of 244 manufacturing managers supports previous research on the dimensions of mentoring. Further, vocational (coaching) and psycho-social (social support) were found to be related to managers' salary level and promotions. Implications of these results for future studies of mentoring are discussed.     

Advanced manufacturing technology and work simplification: An empirical study

This paper is concerned with the effects of advanced manufacturing technology on shopfloor operator jobs and work attitudes. A strong line of argument from labour process theory suggests that such technology will simplify and deskill jobs, and reduce the quality or working life. This proposition was explored within a large electronics company which assembles computer boards, where two different applications of information technology have been experienced. These were compared with two traditional manual assembly jobs. Assessment of job content, perceived job characteristics and operator work attitudes, showed no uniform deskilling effects of advanced manufacturing technologies. Much larger differences existed both between the different new technology applications and between the traditional jobs. This demonstrates that choice of technology is important to skill use and employees' attitudes, as are the choices for the organization of work around it. These are not uniform processes even within a single organization. Experience of operating advanced manufacturing technology was also accompanied by more positive views concerning its impact on the shopfloor.     

Organizational commitment,turnover and absenteeism: An examination of direct and interaction effects

A three component model of organizational commitment was used to study job withdrawal intentions, turnover and absenteeism. Affective commitment emerged as the most consistent predictor of these outcome variables and was the only view of commitment related to turnover and to absenteeism. In contrast, normative commitment was related only to withdrawal intentions while no direct effects for continuance commitment were observed. Continuance commitment, however, interacted with affective commitment in predicting job withdrawal intentions and absenteeism. The form of the interaction was such that high sunk costs tempered relationships between affective commitment and the relevant outcome variables.     

An empirical investigation of European drivers' self-assessment

PROBLEM: Evaluating motorists through self-assessment has attracted much interest in recent literature, which is mainly due to the profound impact various parameters of self-assessment can have on the way motorists deal with hazardous traffic situations. Much of the previous work in this area has been hampered both by the lack of adequate sample sizes and, because of the small samples, the evaluation methodologies used. METHOD: This paper extends previous research in two significant directions: (a) it uses the SARTRE 2 database, which provides more than 17,000 questionnaires from most European countries; and (b) it employs the ordered probit modeling approach, which recognizes the latent nature of self-assessment and explicitly links its dimensions to a set of relevant explanatory variables such as age, gender, region, and income. RESULTS: The results indicate that drivers who rate themselves as both more dangerous and faster than others are, generally, younger men, with higher incomes, break the speed limit more frequently, avoid wearing seat belts, and have been involved in more accidents in the past than other drivers. Interestingly, more experienced and more highly educated drivers assess their driving as less dangerous, but admit to driving faster than other drivers. IMPACT ON INDUSTRY: The methodology used and the results obtained can be a significant help in identifying drivers with high and low self-assessment ratings, which can be useful in planning and implementing road safety information campaigns.     

Factors affecting pedestrian behaviors at signalized crosswalks: An empirical study

Introduction: Safety of pedestrians depends, among other factors, on their behavior while crossing the road. This study aims to assess behaviors of pedestrians at signalized crosswalks. Method: Following a literature review and a pilot study, 25 vital pedestrian crossing factors and behaviors were determined. Then data was randomly collected for 708 pedestrians at 10 lighted crossings in Sharjah (UAE), five at road intersections and five mid-block crossings. Results: Results indicated that 17.4% of pedestrians observed crossed partly or fully on red and that crossing speed was 1.22 m/s, on the average, which is slightly faster than most speeds recorded in the literature. Moreover, female pedestrians were more likely to cross while chatting with others, less likely to cross on red, and more likely to walk slower than male pedestrians. Results also showed that pedestrians who crossed at road intersections walked slower than those who crossed at mid-block crossings. It was also found that longer red pedestrian times and narrower roads tended to encourage pedestrians to cross on red and that the majority of pedestrians did not look around before crossing. Practical implications: Use of the Health Belief Model for pedestrian safety are discussed.     

Understanding driver distractions in fatal crashes: An exploratory empirical analysis

Introduction: Driver distraction has become a significant problem in transportation safety. As more portable wireless devices and driver assistance and entertainment systems become available to drivers, the sources of distraction are increasing. Method: Based on the results of different studies in the literature review, this paper categorizes different distraction enablers into six subcategories according to their fundamental characteristics and how they would affect a driver's likelihood of engaging in non-driving related activities. The review also discusses the characteristics and influence of external and internal distractions. The objective of this study is to examine the effect of different distraction sources in fatal crashes with the consideration of a driver's age and sex. Tukey test, chi-square test of independence, Nemenyi post-hoc test, and Marascuilo procedure have been used to investigate the top distraction sources, the trend of distraction-affected fatal crashes, the effect of different distractions on drives in different age groups, and their influence on female and male drivers. Results: It was found that inner cognitive inferences accounted for the greatest proportion of driver engagement in distractions. Young drivers show a larger probability of being distracted by in-vehicle technology-related devices/objects. Within the group of young drivers, female drivers showed a higher probability than their male counterparts of engaging in distracted driving caused by in-vehicle technology-related devices. Among six subcategories of distractions, drivers older than 80 years old were found to be most likely affected by inner cognitive interferences.     

An empirical analysis of a goal setting questionnaire

This research presents an analysis of a goal setting questionnaire developed by Locke and Latham (1984). The Locke and Latham measure attempts to assess the core goal attributes of ‘specificity’ and ‘difficulty’, as well as other attributes of the goal setting process (such as perceptions about ‘performance feedback’, ‘supervisor support’, ‘conflict’ and ‘stress’). The psychometric properties of the measure were examined using respondents from employees of a large, west-coast electronics organization. A principal components analysis extracted 10 meaningful factors and identified a need for additional items. Results generally supported the meaningfulness of the goal setting factors and provide important directions for future research.     

An integrative model of managerial perceptions of employee commitment: antecedents and influences on employee treatment

An integrative model of antecedents and outcomes of managerial perceptions of employee organizational commitment was developed and tested with 490 employees of a publicly owned U.S. manufacturing firm. The results are consistent with predictions showing that self‐reported affective commitment and supervisor‐focused impression management predicted managerial perceptions of affective commitment, whereas age, tenure, education, training and development, and self‐focused impression management were related to managerial perceptions of continuance commitment. Furthermore, manager‐rated affective and continuance commitment were differentially related to supervisory treatment of the employee (i.e. receiving contingent rewards and non‐contingent punishment). The results of this study show how managers develop perceptions of affective and continuance commitment, and through their associated treatment of employees, has important implications for the ways managers may serve to enhance or detract from employee contributions to the organization.

The role and expectancy participation model: An empirical assessement and extension

Four hypotheses were investigated. The results substantially support and extend the usefulness of Schuler's role and expectancy participation model (1980). Schuler's model posits that participation intervenes to attenuate the relationships between job objectives and role conflicts and ambiguity. Also, participation, role conflict and role ambiguity are assumed to intervene to attenuate the relationships between job objectives and job satisfaction. The four hypotheses were tested using a sample of 187 retail store managers. Results revealed that job objectives were related to the role variables and satisfaction. Participation significantly attenuated the job objectives, role conflict and job satisfaction relationships. Implications for the use of the attributes of job objectives approach to integrate other objective setting paradigms are discussed.     

Justice constructs,negative affectivity,and employee deviance: a proposed model and empirical test

This study tests a model that uses organizational justice variables and the personality trait of negative affectivity to explain two forms of deviant employee behavior. Prior research suggests that deviance can be directed interpersonally or against organizations. We propose a model that links unfavorable perceptions of distributive, procedural, and interactional justice, as well as the dispositional trait of negative affectivity, to both types of deviant acts. To test the model, a survey was distributed to employees from a government agency and an international manufacturer of paper products. Responses to the survey were analysed using structural equation modeling to evaluate the fit of the theoretical model to the data. Results showed that the model fits the data well and that nearly all of the hypothesized relations among constructs were supported. Implications of the results for the prediction and control of deviant behavior are discussed and future research directions are offered. Copyright © 1999 John Wiley & Sons, Ltd.     

The consequences of organizational commitment: Methodological investigation

Extensive research on the consequences of organizational commitment (OC) has been conducted over the past decade. The purpose of this paper is to summarize empirical evidence about the relationship between OC and work outcomes and to examine the effect of methodological decisions on the OC–work outcome relationship. A meta-analysis of 35 studies of the OC–work outcome linkage reveals that the overall empirical relationship between OC and outcome variables is generally weak, but positive. While subgroup analyses reveal that conceptualization, research design, sampling, operationalization and observation technique decisions have a definite impact on the OC–work outcome correlation, the relationship remains essentially weak. Multiple regression analysis reveals that the type of work outcome and methodological decisions explain only 19 per cent of the variance in the OC–work outcome relationship, with conceptualization decisions having the largest impact.     

An empirical investigation of safety climate in container terminal operators

INTRODUCTION: This study empirically evaluates the crucial dimensions of safety climate from a container terminal operator's perspective, specifically in the Port of Kaohsiung. METHOD: Seven safety climate dimensions are identified based on factor analysis: (a) supervisor safety, (b) job safety, (c) coworkers' safety, (d) safety management, (e) safety training, (f) safety rules and special safety training, and (g) job pressure. Cluster analysis is subsequently performed to form worker groups. Respondents are categorized into four groups on the basis of their factor scores in safety climate dimensions: (a) safety management oriented terminal operators, (b) safety training and management oriented terminal operators, (c) job safety and supervisor safety oriented terminal operators, and (d) coworkers' safety oriented terminal operators. RESULTS: Results indicate that safety training and management oriented terminal operators have the best safety performance, followed by safety management oriented terminal operators, job safety and supervisor safety oriented terminal operators, and coworkers' safety oriented terminal operators. Theoretical and practical implications of the research findings are discussed.     

Safety climate and hydrocarbon leaks: An empirical contribution to the leading-lagging indicator discussion

Hydrocarbon (HC) leaks are important initiating events for major accidents in the oil and gas industry. This study explores the extent to which a safety climate indicator from a survey on working conditions undertaken in an oil and gas company (n = 2188) can be used as a leading and/or lagging indicator in relation to HC leaks on 28 offshore installations. It was found that more negative safety climate scores were associated with increasing numbers of HC leaks over a 12-month period following the survey. The safety climate indicator explained more of the variance in HC leaks than technical indicators. HC leaks in the 12-month period preceding the survey did also correlate significantly with the safety climate indicator. More HC leaks during this period were associated with worse scores on the safety climate indicator. Thus, the results support that the safety climate measure could serve as leading and lagging indicator for HC leaks. The results and their possible implications are discussed.     

An empirical examination of personal learning within the context of teams

Using a sample of 588 employees in 59 work teams, we tested a model that situates personal learning within the context of teams, viewing it as a joint function of teams' leadership climate (i.e., transformational leadership) and task characteristics (i.e., task routineness and task interdependence). Consistent with our hypotheses, we found that the positive relationships between transformational leadership climate and the two dimensions of personal learning (relational job learning and personal skill development) were moderated by the nature of the teams' tasks. Specifically, transformational leadership climate was more strongly associated with personal learning for members of teams working on tasks that were less routine, rather than more routine. However, no significant moderation was found for leadership climate and task interdependence. Our findings underscore the importance of taking into account the contextual conditions within which leadership influence occurs while also demonstrating the potential role that leaders can play in promoting employees' personal learning. Overall, our study bolsters theories that conceptualize adult learning as a transaction between people and their social environments and points to a practical need to match leadership styles with team task characteristics to unleash transformational leadership effects.

An empirical assessment of the loose–tight leadership model: quantitative and qualitative analyses

Using questionnaire and interview data, this study attempted to find out whether the organizational loose (participative) and tight (directive) practices are compatible with or contradict each other. Using the theoretical framework of Sagie's ( 1997 ) loose–tight leadership approach, our hypotheses concerned the effects of both practices on the employee's work‐related attitudes, and the mediating role of two variables, cognitive (information sharing) and motivational (exerting effort), in these effects. Data were analysed using two methodological approaches, quantitative and qualitative. Based on a quantitative analysis of the questionnaires given to 101 professional employees of a textile company, partial support was provided for the study hypotheses. A qualitative analysis of in‐depth, semi‐structured interviews with all the employees (n = 20) in one of the company divisions led to similar conclusions. Specifically, we found that although the loose and tight practices affected work attitudes, the interviewees attributed more impact to the tight practice. In addition, none of the study variables mediated the loose impact on attitudes, whereas information sharing (but not exerting effort) mediated the influence of tight practice. Finally, the qualitative analysis revealed a deeper insight into the nature of both leader practices and their possible integration in the decision‐making processes in organizations.

Preventing highway crashes by raising the legal minimum age for drinking: An empirical confirmation

In recent years there has been increased interest in reducing the massive social costs due to alcohol-related motor vehicle crashes. Raising the legal minimum age for purchase and consumption of alcohol beverages has been proposed as one way to reduce alcohol-related crashes among young drivers. Currently, many states are raising the legal age, in contrast to the trend towards lower legal drinking ages in the early 1970s. Recent studies of the effects of raising the drinking age are reviewed, and results from a controlled multiple time-series evaluation of the experience in Michigan are presented. Significant 11 to 28% reductions in alcohol-related crash involvements are shown to be attributable to the raised drinking age in Michigan. Suggestions for further research and discussion of policy implications are included.
