Parent-off spring associations in wintering brent geese: parental investment or mutual assistance?

The continued parent-offspring associations in the Eastern Canadian High Arctic light-bellied brent goose Branta bernicla hrota was examined to determine whether this is an example of continued parental investment or mutual assistance. Adults with juveniles spend more than twice as much time being vigilant and aggressive than do those without offspring. The loss of a partner, however, does not result in the remaining parent increasing parental care but does result in increased 'self-care' by the juveniles. Neither parents nor single-parent juveniles appear to pay an energetic cost relative to non-parental adults and two-parent juveniles, respectively. Differences in the feeding distribution of parents and non-parents and equivalent or better physical condition suggests that families are able to maintain access to a superior food supply over the winter. Passive 'assistance' by juveniles may assist in maintaining this position in favoured areas, and this is achieved with little overt aggression. The present study thus provides no data that show a net cost to parents by remaining with their juveniles over the winter period. Thus, mutual assistance might be a better explanation of the prolonged association rather than a period of parental investment with an overall cost.

Coercion in the Community: A Situated Approach to the Examination of Ethical Challenges for Mental Health Social Workers

Increasingly, mental health social workers in the United Kingdom and elsewhere in the world are employing coercive interventions with clients. This paper explores this trend in the context of community-based settings, using national and international research literature on this subject. It begins with a discussion about the complex, contested nature of ideas on coercion. The authors then explore debates about how coercion is perceived and applied in practice. They choose two forms of coercion*/informal types of leverage, and the legally mandated use of Community Treatment Orders*/to highlight the range of ethical problems and dilemmas that confront practitioners in this field. The authors conclude by developing a tentative, explanatory model to explain how and why mental health social workers should consider a more holistic, situated approach to help deal with ethical concerns about the use of coercion.

Identifying families with multiple problems: Possible responses from child and family social work to current policy developments

In the development of family policy under New Labour there has been a growing tendency to identify groups who are likely to be high in lifetime costs to the state. Investment in such groups is seen as crucial. Whilst the economic case for current investment is compelling, idenitiying one of these groups, ‘families with multiple problems’ raises complex research problems and ethical issues. Reseach indicates that families with multiple problems may be identified on the caseloads of child and family social worker and there are claims that key events such as the registration of a child on the child protection register may indicate such multiple problems. This offers new opportunities for child and family social work to embrace less incident based ways of working in favour of longer term provision of services to address longer term risks.

Humanitarian Travels: Ethical Communication in Lonely Planet Guidebooks

Aside from the more mundane purpose of telling us where to eat, sleep and sightsee in foreign lands, guidebooks communicate an ethical vision that sees travel as the key to reducing cultural differences and inequalities. This article argues that Lonely Planet guidebooks in particular encourage a form of ‘responsible independent travel’ that both reflects and produces a powerful discourse of humanitarianism. By examining the controversy over Lonely Planet’s publication of guidebooks to Burma, this article uncovers the problematic colonial logic embedded in that ethical vision.

Sexual size dimorphism and reproductive investment by female spiders: A comparative analysis

We investigate the association between female reproductive investment, absolute size, and sexual size dimorphism in spiders to test the predictions of the fecundity-advantage hypothesis. The relationships between absolute size and sexual size dimorphism and aspects of female reproductive output are examined in comparative analyses using phylogenetically independent contrasts. We provide support for the idea that allometry for sexual dimorphism is the result of variation in female size more so than male size. Regression analyses suggest selection for increased fecundity in females. We argue that fecundity selection provides the only general explanation for the evolution of sexual size dimorphism in spiders.

Communication, recognition and social work: Aligning the ethical theories of Habermas and Honneth

The modern world is replete with ethical challenges of Orwellian proportions. The violation of human rights and misrecognition of identities are two of the most pressing examples. In this paper, the ethical theories of Habermas and Honneth are aligned as a way of addressing these specific challenges within social work. It is suggested that these theories are complementary, mutually rectifying and concordant at the meta-ethical level of analysis. The alignment is also justified, pargmatically, through the construction of three hypothetical vignettes demonstrating different kinds of practice dilemmas. The need for egalitarian communication and the imperative to recognise human identity in all its dimensions subsequently emerge as the two foundation stones for ethical deliberation in social work.
