Jobs,gender, and self‐efficacy in multiple contexts

This paper focuses on the social psychological correlates of being in an occupation that is sex‐typed against one's own gender‐i.e., cross‐sex incumbency in sex‐typed occupations. Male and female high school teachers and university professors are compared in terms of global self‐esteem as well as in three context‐specific dimensions of self‐efficacy. While no differences in global self‐esteem were revealed, a number of significant differences did emerge in comparisons of self‐efficacy in specific contexts. Our data reveal no uniform effects of cross‐sex incumbency. Male high school teachers, however, did exhibit signs of decreased occupational self‐efficacy, perhaps as a result of the previous female domination of that occupation. Female professors, on the other hand, reported high levels of self‐efficacy on all dimensions. The paper concludes with two hypotheses for further empirical examination, and suggests tht self‐esteem be conceptualized as a multidimensional construct.     

Jobs,Wealth, or Place: The Faces of Community Economic Development

Summary

Multiple and conflicting practices characterize the field of community economic development. Much of the debate about these practices revolves around different understandings of the importance of jobs, wealth, and place. No overarching definition, typology, or theory, however, offers a plausible way to resolve these conflicts about community economic development goals, levers of change, and practices. One promising approach engages the complexity rather than trying to simplify it. Metaphors are multivalent images that call attention to crosscutting issues, underlying assumptions, and hidden connections. Metaphors enable a richer and more creative reading of neighborhoods and economies when used in planning and design. This article explores six metaphors with relevance for community economic development: plugging the leaks, brokering connections, asset management, building ladders and webs, creating level playing fields, and enhancing markets. How to support this complex version of community economic development challenges the ways in which we encourage innovation, investment, and learning.     

Multiple Jobs and Inequality in Earnings

This paper shows that individual and structural factors which determine professors' salaries also influence, in various degrees, the accumulation of earnings from additional sources. As a result, those who receive greater rewards from their main work role are likely to have proportionately higher supplementary incomes. Thus, expanding occupational role-sets increase the inequality in economic rewards in the academic system. It is proposed that the relative effect of each of the salary determinants on extra earnings depends on their ability to generate, directly or indirectly, extra earning opportunities.
The examined factors are professorial rank, research productivity, departmental prestige and the length of academic experience. Professorial rank has been shown as the main determinant of institutional salary level, whereas research productivity is the most crucial factor in generating extra earning opportunities. It is likely that the importance of the latter, in our case, is mainly indirect in that it generates critical intervening resources such as professional reputation, visibility in the academic system and communication network.     

Good Jobs, Good Deeds: The Gender-Specific Influences of Job Characteristics on Volunteering

While research has shown that having a “good” job significantly promotes formal volunteering, we have limited knowledge of how this paid work-to-volunteer work relationship may differ between men and women. Based on the gender-identification spillover theory, we hypothesize that because of the societal expectations that women should be caring, giving and communal, positive job traits such as authority and autonomy promote women’s volunteering more than men’s. Our analysis of data from the National Survey of Midlife in the United States shows that women who exercise supervisory authority on the job volunteer significantly more hours than women who do not, whereas job authority makes no difference in the number of hours volunteered for men. Meanwhile, job autonomy promotes men’s volunteering, but not women’s. Implications of these and related findings for future research on gender and volunteering are discussed.     

Jobs,Gender, and Foetal Protection Policies: From Muller v. Oregon to Johnson Controls

The issue of work place hazards that may threaten the health of an unborn child has long been problematic for women, business decision-makers, and lawmakers. The desire to protect the developing foetus must be balanced against a woman's legal right to get and keep the job of her choice. The issue has never been easy to resolve, as this historical analysis shows. An overview of the potential effects of work place hazards on reproductive health is presented. Relevant fair employment laws are summarized, and a brief history of court cases and employer practices is provided. It is argued that ultimately, foetal protection policies had little or nothing to do with protection of foetuses. They may have had more to do with protecting the employer from potential liability and with perceptions of women's status in the work place than with protecting the next generation. Finally, suggestions for future research are presented.

Jobs for Mothers: Married Women's Labor Force Reentry and Part-Time,Temporary Employment in Japan

This paper explains the increase in middle-aged women reentering the labor force in Japan and their concentration in part-time or temporary employment. Existing explanations attribute women's concentration in part-time employment too narrowly to supply or demand factors. In Japan, both the labor supply of middle-aged women and the demand for part-time workers have increased, but these conditions channel middle-aged women into part-time or temporary employment only when systematic barriers obstruct their access to full-time jobs. Because it plays an important role in women's employment decisions, the rigidity of standard, full-time employment needs greater attention in studies of nonstandard, atypical types of work.     

Mechanization and Changing Skill Requirements of Production Jobs*

Using two sets of U. S. Census data and information from the U. S. Employment Service, this study analyzes the effects of mechanization on skill requirements of blue collar jobs, assessing changes in the distribution of employment in these jobs by race and gender. The results are discussed in the context of high and low levels of mechanization change. Although there was a tendency for mechanization to lower the skill requirements of production work, changes among labor force subgroups are found to differ substantially. Black males increased in high skill jobs regardless of whether these jobs were in industries undergoing high or low rates of mechanization. Females and white males tended to increase more sharply in low skill work, especially in the industries which had high rates of mechanization.     

Science as Snake Oil: Rural Development,Discourse, and the Broken Promise of Tech Jobs in Vermont

This paper examines the public conversation surrounding two failed technology businesses in rural Vermont communities, documenting a particular techno-development discourse. Engaging with the literatures of rural development and science and technology studies (STS), the paper frames this discourse as a mechanism of power exercised by private capital. It analyzes how perspectives shared in news and social media functioned to attribute financial, technological, and moral authority to developers while dividing communities and scapegoating the state. Our work highlights the need for scholars to be conscious of techno-development discourses that prioritize capital interests over community interests. Rather than using hegemonic conceptualizations of technology, we advocate for development that advances more flexible, local understandings of technology. And rather than centering high-tech development as a vehicle for extending prosperity across space, we propose that greater attention be paid to extending high wages across industrial sectors.     

Working‐Class Jobs and New Parents' Mental Health

Little research has explored linkages between work conditions and mental health in working‐class employed parents. The current study aims to address this gap, employing hierarchical linear modeling techniques to examine how levels of and changes in job autonomy, job urgency, supervisor support, and coworker support predicted parents' depressive symptoms in a sample of 113 dual‐earner couples interviewed five times across the transition to parenthood. Increases in job autonomy and decreases in job urgency predicted fewer depressive symptoms in fathers at 1 year postpartum. For mothers, coworker support predicted fewer depressive symptoms, and supervisor support mitigated the negative effects of job urgency on depressive symptoms. Higher work hours coupled with low job urgency predicted declines in mothers' depressive symptoms across the first year of parenthood. Our findings suggest that interventions that lead to greater autonomy, less job urgency, and more supportive work relations may enhance employee well‐being among working‐class families.
