There are ongoing management and societal challenges affecting volunteering participation. These place a premium on organizations identifying individuals that currently do not volunteer but have the willingness and capacity to do so, the “Potentials”. Supplementing the limited non-volunteer literature, we seek to quantify this potential volunteer pool using constructs aligned to the willingness, capability and availability dimensions from Meijs et al.’s (Volunt Action 8:36–54, 2006) volunteerability framework. Using binary logistic regression testing with a nationally representative sample of Australian volunteers and non-volunteers, we found partial support for the framework’s willingness and capability dimensions determining volunteer status. We then applied a predictive equation to the non-volunteer sample to calculate their percentage likelihood of volunteering, to identify a cohort of “Potential” volunteers. Further testing revealed statistically significant differences between this cohort compared to other non-volunteers based on various interventions for promoting volunteering. The implications of our novel study and an associated research agenda are discussed.

Many panel data-sets contain father-reported fertility data. Yet, since men tend to underreport past fertility--especially daughters or children from previous marriages--using such data can lead to significantly biased results when estimating household labour supply models. For example, when analysing fertility data from the Panel Study of Income Dynamics, which has a significant retrospective component, fathers' labour supply appears more responsive to the births of sons than to daughters (Lundberg and Rose, Review of Economics and Statistics 84(2): 251-268, 2002). However, no evidence for this differential can be found in a much larger sample of Current Population Survey data from the same population. It is important for researchers to consider the provenance of data on fertility variables and to undertake robustness checks with data reported by women whenever possible.  相似文献

Clearly, the necessary changes in the law and culture will not come easily or quickly. But, transcending all forms of these labor market segments is a set of concerns that arguably should spur a search for common ground between labor and management. The proliferation of automated technologies, together with the continuing impact of foreign competition with cheap labor markets, has led some to predict that, over the next quarter century, we will witness the elimination of the blue-collar, mass assembly-line worker from the production process.14 Moreover, the theory that those losing jobs in the manufacturing sector will be generally absorbed into the service sector is losing currency as it is becoming clear that service jobs are, themselves, not invulnerable either to offshore outsourcing (e.g., telephone operators, data processors) or to automated technology (e.g., bank tellers, office secretaries). Nor is it realistic to expect the new “knowledge sector” to absorb more than a fraction of the unemployed and underemployed casualties of this transformation. As a result, the widening gap between the haves and have nots will only continue to grow. As the trend accelerates, certain possibilities for a labor-management accommodation emerge. For one thing, although corporations may be enjoying short-term gains from present wage stagnation, downsizing, outsourcing, and casting off of permanent employees, the longer term effects include a work force with considerably diminished consumer purchasing power. In some industries, corporations are already acknowledging the adverse effects of this trend. Furthermore, as employers are contributing into pension funds on behalf of fewer and fewer “employees,” the forced savings pool that has for many years constituted a primary financing source of capital investments in our economy, will gradually be depleted.15 At the same time as employers are coming face to face with the disadvantages of the union-free environment they have so long sought, employers are also rediscovering the contributions to productivity, quality, and efficiency that can be gained from a truly empowered work force with an independent voice in the workplace. All of this should lead an enlightened management to place less currency on resisting unionization and other legitimate forms of independent employee representation, and to join labor in advocating strong labor standards and effective labor law for all four of the labor market segments that exist today and will exist tomorrow. The authors wish to convey their deep appreciation for the invaluable contributions to this paper made by David Silberman of Bredhoff & Kaiser and Craig Becker, Associate General Counsel, Service Employees International Union. Another version of this paper was published in Labor Lawyer.  相似文献

Although much has been written aboutworkaholism, rigorous research andtheoretical development on the topic is in its infancy.We integrate literature from multiple disciplines andoffer a definition of workaholic behavior. We identify three types ofworkaholic behavior patterns: compulsive-dependent,perfectionist, and achievement-oriented workaholism. Apreliminary model is proposed; it identifies potential linkages between each type of workaholismpattern and important outcomes such as performance, joband life satisfaction, and turnover. Specificpropositions for future research are articulated. Weconclude that, depending on the type of workaholicbehavior pattern, workaholism can be good or bad, andits consequences may be experienced or evaluateddifferently by individuals, organizations, and societyat large. Researchers and managers should avoidmaking judgments about the positive or negative effectsof workaholism until more carefully controlled researchhas been published.  相似文献

Analysis approaches to the evaluation of community interventions must be sensitive to a wide variety of analytic contaminants that may bias the statistical assessment of changes in outcome measures. These contaminants include model misspecifications related to failures to control for community-specific time trends, temporal autocorrelated errors in equations, spatial autocorrelated errors among geographic units, and other failures of unit independence otherwise indexed by estimated intraclass correlations. Although an enormous amount of progress has been made toward the solution of many of these analytic problems over the past years, the contemporary evaluator of community interventions is left with a number of unenviable design and analysis choices; choices that inevitably force an assessment of the relative threats of different sources of error to the internal and external validity of the evaluation. This article describes the choices made for the evaluation of the Community Trial Project outcome data.  相似文献

The paper analyzes autobiographical acounts of the experience of chronic illness and its treatment to develop a sociological theory of the self. It is suggested that ‘self’ is not a biologistic or psycologistic thing. Rather self is autobiographical narrative – hence the narrative self. It is argued that four elements constitute such narrative selves in autobiographical discourse: evaluative relationships between events in time; cosmology; power relationships; and conceptualisation of self as object.  相似文献
