Part-time Employment and Effects on Australian Social Work Students: A Report on a National Study

Abstract

University students, nationally as well as internationally, engage in employment to supplement income while studying. Social work students are no different in this respect. There have long been questions about whether such part-time work has an adverse impact on student academic performance. This paper explored the experiences of social work students enrolled on-campus across three Australian universities as reported through a survey and focus groups. The research found that social work students did engage in significant amounts of paid employment while studying, that there were both positives and negatives for students depending on the nature of their employment, and that compromises needed to be made in juggling competing responsibilities. Accessing and living on inadequate government benefits imposed particular stressors. The findings have implications for the ways in which social work education is structured, especially in terms of flexibility, and demonstrated that part-time work also offers opportunities for student learning.     

Women's Perception of the Divorce Experience: A Qualitative Study

ABSTRACT

Divorce is a personal experience, often negative, and each couple experiences it differently. However, the divorce experience may provide opportunities for personal growth. The purpose of this qualitative study was to understand the challenges and growth opportunities women who have divorced experience from their own perspective. Ten women with similar backgrounds participated in personal interviews. Individual interviews revealed the following themes: (a) dating reflections, (b) married life, (c) self-perceptions, (d) support or lack of support, (e) family, (f) personal emotions, (g) personal growth, and (h) the future.

Impact of Postdivorce Sibling Structure on Adolescent Adjustment to Divorce

A sample (N = 222) of middle school, high school, and college students were surveyed with regard to their adjustment to their parents’ divorces in specific domains, including coparenting, financial strain, and overall adjustment. With time since the divorce covaried, youth living with half-siblings, stepsiblings, or both (HSS) rated their experiences consistently more positively than youth living with full biological siblings only (FBS). HSS youth reported stronger perceptions that life has gotten better, parents are working together to raise them, and there are no lingering financial effects. There were no main effects for age, but an interaction of sibling structure and gender found male adolescents in the FBS group sometimes had more negative ratings than any of the other groups. Our findings contrast with prior studies suggesting that HSS youth do not adjust as well as FBS youth.     

Feddersen and Pesendorfer meet Ellsberg

The Condorcet Jury Theorem formalises the “wisdom of crowds”: binary decisions made by majority vote are asymptotically correct as the number of voters tends to infinity. This classical result assumes like-minded, expected utility maximising voters who all share a common prior belief about the right decision. Ellis (Theor Econo 11(3): 865–895, 2016) shows that when voters have ambiguous prior beliefs—a (closed, convex) set of priors—and follow maxmin expected utility (MEU), such wisdom requires that voters’ beliefs satisfy a “disjoint posteriors” condition: different private signals lead to posterior sets with disjoint interiors. Both the original theorem and Ellis’s generalisation assume symmetric penalties for wrong decisions. If, as in the jury context, errors attract asymmetric penalties then it is natural to consider voting rules that raise the hurdle for the decision carrying the heavier penalty for error (such as conviction in jury trials). In a classical model, Feddersen and Pesendorfer (Am Politi Sci Rev 92(1):23–35, 1998) have shown that, paradoxically, raising this hurdle may actually increase the likelihood of the more serious error. In particular, crowds are not wise under the unanimity rule: the probability of the more serious error does not vanish as the crowd size tends to infinity. We show that this “Jury Paradox” persists in the presence of ambiguity, whether or not juror beliefs satisfy Ellis’s “disjoint posteriors” condition. We also characterise the strictly mixed equilibria of this model and study their properties. Such equilibria cannot exist in the absence of ambiguity but may exist for arbitrarily large jury size when ambiguity is present. In addition to uninformative strictly mixed equilibria, analogous to those exhibited by Ellis (Theor Econo 11(3): 865–895, 2016), there may also exist strictly mixed equilibria which are informative about voter signals.

     

A Bayesian Inventory Model Using Real‐Time Condition Monitoring Information

Lack of coordination between machinery fault diagnosis and inventory management for spare parts can lead to increased inventory costs and disruptions in production activity. We develop a framework for incorporating real‐time condition monitoring information into inventory decisions for spare parts. We consider a manufacturer who periodically replenishes inventory for a machine part that is subject to deterioration. The deterioration is captured via condition monitoring and modeled using a Wiener process. The resulting degradation model is used to derive the life distribution of a functioning part and to estimate the demand distribution for spare parts. This estimation is periodically updated, in a Bayesian manner, as additional information on part deterioration is obtained. We develop an inventory model that incorporates this updated demand distribution and demonstrate that a dynamic base‐stock policy, in which the optimal base‐stock level is a function of some subset of the observed condition monitoring information, is optimal. We propose a myopic critical fractile policy that captures the essence of the optimal policy, but is easier to compute. Computational experiments indicate that this heuristic performs quite well relative to the optimal policy. Adaptive inventory policies such as these can help manufacturers to increase machine availability and reduce inventory costs.     

The Mathematics of Electoral District Allocation in New Zealand

This paper outlines the implicit conceptual basis of New Zealand's electoral district allocation, as embodied in the Electoral Act 1993. It puts the words of the Act into simple mathematical formulae and describes how these concepts are implemented in the Government Statistician's electoral calculations, with examples from the 1997 calculations. The paper shows how the Māori Option affects the number of Māori electoral districts, and describes an unexpected effect of the Option on the number of General electoral districts.     

Integrating feminist and sociological thought: The life and work of helena Znaniecka Lopata

This work is a biographical essay on the academic career of Helena Znaniecka Lopata, a noted sociologist in her own right and the daughter of Florian Znaniecki, a principal contributor to qualitative and humanistic sociology. Lopata’s story documents the difficulties of establishing a career in a social climate that did not place high value on women beyond their wife and mothering roles. Once she defied her cultural expectations, she also had to overcome the shadow of her father’s legacy and, finally, she had to find acceptance for doing research on women’s everyday life experiences. Lopata’s work provides important insights into the sociological study of social roles and of gender as a structural component of stratified social systems. She has published articles on the women’s movement, politics and the family, and the abortion controversy. Her book,Feminism and the Women’s Movement: Dynamics of Change in Social Movement Ideology and Activism, is forthcoming from Unwin Hyman. A version of this paper was presented at the 1989 Annual Meeting of the American Sociological Association, San Francisco, CA.
