Data aggregation for <Emphasis Type="Italic">p</Emphasis>-median problems

In this paper, we use a pseudo-Boolean formulation of the p-median problem and using data aggregation, provide a compact representation of p-median problem instances. We provide computational results to demonstrate this compactification in benchmark instances. We then use our representation to explain why some p-median problem instances are more difficult to solve to optimality than other instances of the same size. We also derive a preprocessing rule based on our formulation, and describe equivalent p-median problem instances, which are identical sized instances which are guaranteed to have identical optimal solutions.     

Zelda Foster and her contributions to social work in end-of-life care

This article is both a memoir of one social worker's professional collaboration with Zelda Foster and a tribute to Zelda's legacy in the form of an educational resource on end-of-life care. It reviews achievements of Zelda Foster in social work practice and teaching related to death and dying. Resources presented in this article were supported by the Soros Foundation's Project on Death in America, a funded grant project to which Zelda contributed. The end-of-life care education, training and informational tools discussed in this article are examples of ongoing efforts in the social work profession to improve the lives of the dying and bereaved.     

Avoid falling for a jerk(ette): Effectiveness of the Premarital Interpersonal Choices and Knowledge Program among Emerging Adults

Premarital education may help emerging adults form healthy relationships, but evaluation research is needed, particularly with community samples. We studied emerging adults in the Premarital Interpersonal Choices and Knowledge (PICK) program, using a pre‐ to post‐ and a posttest‐then‐retrospective‐pretest design to examine change in perceived relationship skills, partner selection, relational patterns, and relationship behaviors and attitudes. Mixed models analyses showed that scores for the treatment group (n = 682) increased from pre to post on all four outcomes. Changes in scores for the nonequivalent comparison group (n = 462) were nonsignificant. In addition, significant differences between pre‐ and retrospective prescores demonstrated evidence for response shift bias. The results suggest that the PICK program helps participants increase their knowledge regarding the components of healthy relationship formation.     

Marginality amidst plenty: Pathways into homelessness for older Australians

In this paper, drawing on in‐depth interviews, we illustrate that despite the significant overall increase in the wealth of older Australians over the last two decades, a sizeable proportion of older Australians (65 and over) are in a vulnerable accommodation situation and many face the possibility of finding themselves homeless. This is especially so for those older Australians who are dependent on government for their income and are living in private rented accommodation. We show that the changing nature of the housing market means that often our informants were not able to find affordable, adequate and secure accommodation. The death of a spouse, rent increases and eviction are common precipitators of a slide into a situation of imminent homelessness. The restructuring of the welfare state and the virtual freeze on the building of social housing means that older private renters who face eviction often have nowhere to turn. Besides not being able to rely on the market or government, many have minimal or no family and social networks.     

Union administrative practices: A comparative analysis

In response to growing challenges, many labor organizations are reevaluating themselves in an effort to become more efficient and effective. Their efforts, however, are limited by their frames of reference. Seldom do unions compare practices across labor movements. To expand these frames of reference we compare union administrative practices in three countries: Canada, the United Kingdom, and the United States. Two specific areas of union administration are examined — human resource/personnel practices and strategic planning. Results from these countries are presented and analyzed to identify and explain similarities and differences.     

Taxes,risky investments,and the simultaneous choice of organizational form and financing

By taking explicit account of liability limitations, we analyse the influence of taxes on the simultaneous choice of organizational form and financing. In a two-state model for a single reporting period investors striving for maximisation of expected utility choose the organizational form (with or without liability limitation) in which they implement a given risky real investment and decide how they finance it (equity or debt). We demonstrate that liability limitations result in tax-relevant differences between organizational forms. Thus, for example, the tax bases differ in relation to the chosen liability-contingent debt capital compensations as well as to tax loss offset rules. Therefore, even in the event of identical tax rates, taxes can influence the decision regarding the organizational form.     

The dark arts of good people: How popular culture negotiates ‘spin’in NBC's The West Wing1

This paper argues that the popular American TV series The West Wing provides, within popular culture, a sympathetic and realistic view of the work of the political ‘spin doctor’. This enterprise is sociolinguistically interesting because of the extensive range of metalinguistic and metacommunicative reflection which it involves. The West Wing centres its storytelling within the world of the spin doctor, thus making such characters central to the narrative: further, it constructs them as likeable, virtuous characters who are also clever. Their cleverness is a matter of sociolinguistic performance expressed in dialogue which displays their professional writing craft skills and their spontaneous witty badinage.
