TEACHING WATER RESOURCES POLICY TO UNWERSITY SCIENCE AND ENGINEERING STUDENTS: OPPORTUNITIES AND CHALLENGES1

ABSTRACT: Effectively teaching water resources policy to university science and engineering students is both important and difficult. Most careers in the water resources field require an understanding of the comprehensive governmental regulatory structure affecting water use. Also, few science and engineering curricula encourage their students to take policy courses. Successful approaches to teaching water resources policy might include epistemological comparisons, case studies, issue maps, and interactive simulations. Obstacles to the effective teaching of this subject include students' insufficient preparation and student disdain and cynicism. These obstacles may be mitigated by requiring a prerequisite, developing a glossary of policy-related terms, and introducing the course through lectures emphasizing realistic views of the water resources management field and the nature of the American political system.     

Stayers versus movers: Social capital and early career imprinting among young professionals

We investigate what interfirm career mobility patterns would emerge if individuals are motivated by the job rewards they obtain as a function of their experience in organizations. We articulate two career strategies that individuals employ to navigate their early careers—commitment to a single employer and “job hopping” between different employers. Each strategy generates social capital (an individual's structure of social relations) but of a different kind. Embeddedness in the same organization over time develops a strong local identity and reputation within the firm. Boundary spanning through experience in different organizations creates opportunities for connecting people and ideas and for knowledge transfer between firms. We posit and present evidence that the choice between these two strategies is conditioned by social experience at the onset of one's career—the length of tenure with the first employer—which sorts individuals into “stayers” and “movers.”     

Is using work–life interface benefits a career‐limiting move? An examination of women,men, lone parents,and parents with partners

Using a large national sample based on Workplace and Employee Survey data collected by Statistics Canada in 2001 and 2002, we examined the effects of employee usage of seven organizational work–life interface benefits on promotions. Analysis predicted promotions in 2002 when number of promotions received by 2001 were controlled. The main effect of using work–life interface benefits on promotions was positive, indicating that using these benefits is not a career‐limiting move. Gender, presence of young children, and marital status interacted with the use of work–life interface benefits. Single parents benefitted less than other employees from using work–life interface options. Altogether, these findings suggest that the ongoing positive effects of conservation of time and energy resources for employees outweigh the initial short‐term negative effects of signaling and stigmatization.

Dynamics of calling: A longitudinal study of musicians

The dominant view of calling among management scholars is that it is a stable construct that does not change. This view has resulted in a research void about calling's early development and subsequent evolution. Insight into the dynamic process through which callings develop is fundamental to understanding its role in people's careers and lives. In this study, I focus on the antecedents of calling, a consuming, meaningful passion people can experience toward a domain. I propose a dynamic model in which calling can change over time and can be shaped by antecedent factors, specifically, through people's ability, behavioral involvement, and social comfort in the area toward which they feel a calling. I tested these ideas in a seven‐year, four‐wave prospective longitudinal survey study of 450 amateur musicians. Multilevel analyses indicate individuals who were more behaviorally involved and felt higher social comfort in the calling domain (e.g., music) experienced higher levels of calling early on but experienced a decline in calling over time. Individuals' ability in the calling domain was not related to initial calling or change in calling. I discuss the implications for theory and research on calling, meaning of work, and the dynamics of careers. Copyright © 2012 John Wiley & Sons, Ltd.

Relationships between psychological contract breach and employee well‐being and career‐related behavior: The role of occupational future time perspective

Relationships between psychological contract breach and employee well‐being and career‐related behavior cannot sufficiently be explained by social exchange and reciprocity theories, yet the alternative mechanisms underlying these associations are currently not well understood. Based on the psychological contract perspective on careers, the goal of this study was to examine indirect effects of psychological contract breach on emotional engagement, emotional exhaustion, and career‐related behavior through two dimensions of occupational future time perspective (i.e., focus on opportunities and focus on limitations). Data came from 405 employees in Australia, who responded to three surveys across 12 months. Results showed that psychological contract breach had indirect effects on emotional engagement and exhaustion through focus on opportunities and focus on limitations, respectively, and on career‐related behavior through focus on opportunities. Another mechanism, psychological contract violation, was only related to employees' organizational deviance. These findings highlight the important role of occupational future time perspective dimensions as employees' evaluations of future career‐related opportunities and limitations. These evaluations may change in response to psychological contract breach and, in turn, might impact on employee well‐being and career‐related behavior.
