Classical definitions of motivation typically involve two main components: direction and activation. Motivated behavior is directed toward or away from particular stimuli (i.e., appetitive and aversive motivation). Furthermore, activational aspects of motivation refer to the observation that motivated behavior is characterized by substantial activity, vigor, persistence, and exertion of effort in both the initiation and maintenance of behavior. Although separate neural systems direct organisms toward distinct motivational stimuli (e.g., food, water, sex), there appears to be a common circuitry regulating behavioral activation and the exertion of effort. Mesolimbic dopamine is one of the brain systems mediating activational aspects of motivation and exertion of effort. This system integrates aspects of motivation and motor control functions involved in the instigation of action. Research on the neurobiology of effort has contributed to our understanding of the pathophysiology of neurological and psychiatric disorders that are characterized by motivational dysfunction.

The modern workplace contains many physical and interpersonal hazards to employee physical and psychological health/well-being. This chapter integrates the literatures on occupational safety (i.e., accidents and injuries) and mistreatment (physical violence and psychological abuse). A model is provided linking environmental (climate and leadership), individual differences (demographics and personality), motivation, behavior, and outcomes. It notes that some of the same variables have been linked to both safety and mistreatment, such as safety climate, mistreatment climate, conscientiousness, and emotional stability.

There is an increased emphasis on internal control in the governmental sector. We compare finance officer assessments of internal control to auditor assessments for a sample of Michigan municipalities. On average, the finance officers' assessments of their control systems were more favorable than the assessments made by auditors from a regional CPA firm with a large governmental practice, suggesting that auditor reports on internal control may result in a more conservative evaluation of the control system than reports provided by management. One measure of the effectiveness of the internal control system is its ability to prevent errors. We compare the finance officer and auditor assessments of internal control to the number of audit adjustments as an objective measure of the accuracy of the control assessments. The internal control assessments made by auditors were significantly more highly correlated with the number of audit adjustments than those made by finance officers. This suggests that the accuracy of internal control reports may be improved if the reports are prepared by auditors.

This study is an attempt to contribute to an emerging stream of research, which attempts to explore how work commitment forms affect one another and how together they serve to influence work behaviour and outcomes.Design/methodology/approach – Drawing on five universal forms of work commitment, we tested the relationships between two work commitment models and two forms of employee withdrawal intentions: from their organisation and from their occupation. To this end, we investigated professional employees (social workers) employed in the Israeli healthcare system through a structured questionnaire.Findings – Path analysis results cast doubt on the applicability of both models in their original form, across scenarios. At the same time, with some modifications, both models show a good potential for explaining variance in employee withdrawal intentions from both their organisation and their occupation.Originality/value – This research contributes to work commitment literature by providing empirical findings and theoretical interpretations regarding the role of a particular professional setting in explaining the interrelationships among models of work commitment, and how some constellations of different work commitment foci explain multiple withdrawal intentions.

In this chapter organizational theory is used to clarify and synthesize the large and diverse literature on the relationship between managed care (MC) and ethnic differences in access to health services. MC practices are classified by whether they are used by health care organizations to define their boundaries or to coordinate care. MC practices used to coordinate care are further categorized as one of five types: rules and programs, authority, goal setting, culture, or client coordination. This review also presents hypotheses derived from this literature that specify the predicted effects of MC practices on ethnic differences in access to health services. It was found that few of these hypotheses had been empirically investigated and although some evidence was found that MC boundary-setting practices disadvantage minorities, there were not consistent findings with respect to those practices used to coordinate care.
