Engaging in the Crooked Timbre of Humanity: Value Pluralism and Social work

The field of social work ethics is changing. While more established positions, such as utilitarianism and deontology, continue to influence social work thinking and practice, emergent approaches are taking hold, leading to a radical examination of social work as an ethical discipline. To contribute to this unfolding debate, this article examines Isaiah Berlin's notion of value pluralism and its contribution to social work. The argument proceeds by summarising and categorising some of the traditional and emergent theories shaping social work according to metaphors of the ‘head’ (the justice-oriented, rational approaches) and the ‘heart’ (the grounded, particularistic and care-focused approaches). Berlin's value pluralism is then adopted to contend that social work needs to hold both ‘head’ and ‘heart’ ethics in a vital equilibrium to generate the ethics of the ‘hand’ (i.e. the practical response to contested areas of need) and the ‘feet’ (the commitment to change and well-being). These metaphors are then mapped on to a decision-making process and applied to the fraught area of adoption without parental consent

Single mating in orchid bees (Euglossa, Apinae): implications for mate choice and social evolution

Neotropical orchid bees (Euglossini) are conspicuously different from other corbiculate bees (Apinae) in their lack of advanced sociality and in male use of acquired odors (fragrances) as pheromone-analogues. In both contexts, orchid bee mating systems, in particular the number of males a female mates with, are of great interest but are currently unknown. To assess female mating frequency in the genus Euglossa, we obtained nests from three species in Mexico and Panama and genotyped mothers and their brood at microsatellite DNA loci. In 26 out of 29 nests, genotypes of female brood were fully consistent with being descended from a singly mated mother. In nests with more than one adult female present, those adult females were frequently related, with genotypes being consistent with full sister-sister (r = 0.75) or mother-daughter (r = 0.5) relationships. Thus, our genetic data support the notions of female philopatry and nest-reuse in the genus Euglossa. Theoretically, single mating should promote the evolution of eusociality by maximizing the relatedness among individuals in a nest. However, in Euglossini this genetic incentive has not led to the formation of eusocial colonies as in other corbiculate bees, presumably due to differing ecological or physiological selective regimes. Finally, monandry in orchid bees is in agreement with the theory that females select a single best mate based on the male fragrance phenotype, which may contain information on male age, cognitive ability, and competitive strength.

Qualifications, examinations and assessment: views and perspectives of students in the 14–19 phase on policy and practice

This paper brings to the forefront students’ views on one of the most significant aspects of education in the 14-19 phase, specifically the qualifications, examinations and assessment they experience. In this respect the paper foregrounds students as ‘policy actors’, they are significant players in the mediation of national qualification systems rather than just subjects in their implementation. Data from a national dataset of focus groups with 243 students from the 14-19 phase is presented. Key themes are highlighted relating to young people’s experiences of qualifications, examinations and assessment at this stage of education in a context of continuous initiatives and change as well as the impact of students being on the receiving end of qualification reform in situ which can be confusing, unsettling and ultimately detrimental to future success.
