Over recent years the findings of a number of quantitative research studies have been published in the UK on gender and achievement. Much of this work has emanated from Stephen Gorard and his colleagues and has not only been highly critical of existing approaches to handling quantitative data but has also suggested a number of alternative and, what they claim to be, more valid ways of measuring differential patterns of achievement and underachievement between groups. This article shows how much of this work has been based upon rather under-developed measures of achievement and underachievement that tend, in turn, to generate a number of misleading findings that have questionable implications for practice. It will be argued that this body of work provides a useful case study in the problems of quantitative research that fails to engage adequately with the substantive theoretical and empirical literature and considers some of the implications of this for future research in this area.

Using Northern Ireland as a case study, this paper explores how lawyers responded to the challenges of entrenched discrimination, sustained political violence and an emerging peace process. Drawing upon the literature of the sociology of lawyering, it examines whether lawyers can or should be more than ‘paid technicians’ in such circumstances. It focuses in particular upon a number of ‘critical junctures’ in the legal history of the jurisdiction and uncouples key elements of the local legal culture which contributed to an ethos of quietism. The paper argues that the version of legal professionalism that emerged in Northern Ireland was contingent and socially constructed and, with notable exceptions, obfuscated a collective failure of moral courage. It concludes that facing the truth concerning past silence is fundamental to a properly embedded rule of law and a more grounded notion of what it means to be a lawyer in a conflict.

Objectives: To investigate whether older adults participating in social activities are more likely to maintain or achieve recommended waist circumference (WC) levels. Method: A total of 4,280 older adults who participated in Wave 2 (baseline) and Wave 4 (follow-up) of the English Longitudinal Study of Ageing. WC was measured by a nurse in both study waves. Results: Participation in education, arts, music groups, evening classes, and in charitable associations was associated with maintaining recommended WC only in those men whose WC was in the recommended range at baseline. Participation in social activities was not associated with achieving recommended WC in women or men with initially large waist. Discussion: Participation in cultural and charitable activities may help in maintaining a recommended level of WC in older men with WC originally in the recommended range.

This article draws upon data from an indepth ethnographic study of five- and six-year-old children in an English multi-ethnic, inner city primary school. It focuses on the significance of ‘race’ within young girls’ peer group relations and the ways in which the social dynamics that underlie those relations provide the context for understanding the particular nature and form that racism takes among the girls. This is done through a focus on the experiences of South Asian girls within the group. Within this, the article has two main aims. First, it aims to contribute to the literature within the sociology of education by extending the existing research focus on racism within teacher/pupil interactions to include an understanding of racism as it manifests itself among the children’s peer-group relations. Second, in adapting and applying Pierre Boudieu’s concepts of capital and field, the article also offers a contribution to the literature within the sociology of ‘race’ and ethnicity by suggesting one potentially fruitful way in which racism can be understood within specific social contexts.

The past decade has witnessed the publication of a growing number of important ethnographic studies investigating the schooling experiences of Black students. Their focus has largely been upon student-teacher relations during the students' last few years of compulsory schooling. What they have highlighted is the complexity of racism and the varied nature of Black students' experiences of schooling. Drawing upon data from a year-long ethnographic study of an inner-city, multi-ethnic primary school, this paper aims to compliment these studies in two ways. Firstly the paper will broaden the focus to examine how student peer-group relations play an integral role, within the context of student-teacher relations, in shaping many Black students' schooling experiences. By focussing on African/Caribbean infant boys, it will be shown how student-teacher relations on the one hand, and peer-group relations on the other, form a continuous feed-back loop; the products of each tending to exacerbate and inflate the other. Secondly, by concentrating on infant children, the paper will assess the extent to which these resultant processes and practices are also evident for Black pupils at the beginning of their school careers - at the ages of five and six.

Several authors have shown that neutrophil generation of reactive oxygen species (ROS) declines with advancing age. Similar changes have also been suggested in monocytes. In both cases alterations in second messenger activity have been implicated as the most likely explanation for these observations. The aim of this study was to investigate the effect of age on phagocyte ROS generation, stimulated by the direct activation of protein kinase C (PKC). Venous blood was drawn from normal healthy subjects, cells were separated on a double density gradient into mononuclear and polymorphonuclear (pmn) cells. Phorbol myristate acetate (PMA) was employed as a cell stimulus. Superoxide generation was measured by cytochrome c reduction and myeloperoxidase (MPO) products by measurement of peak luminol chemiluminescence (CL). Fifty-eight subjects, 25 males and 33 females, were studied, median age 49 years (range 26-88 years). Polymorphonuclear cell superoxide generation was significantly higher in males and there was a trend towards higher pmn MPO product generation in males. Using Spearman's ranked correlation coefficient, monocyte superoxide generation was negatively correlated with age (r = -0.473, P <0.001). No changes in the generation of MPO products was found. There were also trends towards a negative correlation of pmn cytochrome c reduction and peak luminol CL with age in males but not females. Since PMA directly activates protein kinase C, reduced monocyte superoxide generation with increasing age appears to be related to alterations in the ROS generating system downstream of the cell receptor. Impaired monocyte superoxide generation may have implications for non-specific defence against certain infections and early tumour growth in the elderly. Factors underlying these changes in monocyte function therefore require further study.

The relationship between parental background and children's educational outcomes has been a dominant theme within the sociology of education. There has been an on-going debate as to the relative merits of explanations which focus on the role of socio-cultural reproduction and those which focus on rational choice. However, many empirical studies within the social stratification tradition fail to allow for children's own agency in shaping the relationship between social background and schooling outcomes. This paper draws on the first wave of a large-scale longitudinal study of over 8,000 nine-year-old children in Ireland, which combines information from parents, school principals, teachers and children themselves. Both social class and parental education are found to have significant effects on reading and mathematics test scores among nine year olds. These effects are partly mediated by home-based educational resources and activities, parents' educational expectations for their child, and parents' formal involvement in the school. More importantly, children's own engagement with, and attitudes to, school significantly influence their academic performance. The influence of children's own attitudes and actions can thus reinforce or mitigate the effect of social background factors. The analysis therefore provides a bridge between the large body of research on the intergenerational transmission of inequality and the emerging research and policy literature on children's rights.

This paper examines the structure of popular conceptions of the new genetics, and assesses why genetics has been so readily accepted in medicine and in the public discourse. Adapting Rene Dubos' classic analysis, Mirage of Health, we examine the new genetics by comparing it to Dubos' analysis of the structure and limits of germ theory. Germ theory focuses on the internal rather than the external environment, emphasises a doctrine of specific aetiology, and adopts the metaphor of the body as a machine. The germ theory model narrowed our vision about disease aetiology, proved misleading in some cases, yet remained the basis for clinical medical models of disease. In recent years, genetics has moved to the cutting edge of medical research and thinking about disease and behaviour. The structure of popular conceptions of the new genetics shows remarkable parallels with germ theory. This has eased the acceptance of genetics but simultaneously raises questions about these genetic explanations. An appearance and allure of specificity privileges genetic explanations in the public discourse; on examination, this specificity may prove to be a mirage.

The health status of the oldest old, the fastest increasing population segment worldwide, progressively becomes more heterogeneous, and this peculiarity represents a major obstacle to their classification. We compared the effectiveness of four previously proposed criteria (Franceschi et al., 2000; Evert et al., 2003; Gondo et al., 2006; Andersen-Ranberg et al., 2001) in 1160 phenotypically fully characterized Italian siblings of 90 years of age and older (90+, mean age: 93 years; age range: 90–106 years) belonging to 552 sib-ships, recruited in Northern, Central and Southern Italy within the EU-funded project GEHA, followed for a six-year-survival. Main findings were: (i) ‘‘healthy’’ subjects varied within a large range, i.e. 5.2% (Gondo), 8.7% (Evert), 17.7% (Franceschi), and 28.5% (Andersen-Ranberg); (ii) Central Italy subjects showed better health than those from Northern and Southern Italy; (iii) mortality risk was correlated with health status independently of geographical areas; and (iv) 90+ males, although fewer in number, were healthier than females, but with no survival advantage. In conclusion, we identified a modified version of Andersen-Ranberg criteria, based on the concomitant assessment of two basic domains (cognitive, SMMSE; physical, ADL), called ‘‘Simple Model of Functional Status’’ (SMFS), as the most effective proxy to distinguish healthy from not-healthy subjects. This model showed that health status was correlated within sib-ships, suggesting a familial/genetic component.

How do the large scale structures of capitalism and the local social relations of workplaces and organisations shape each other? Through a series of European studies of capital and labour's shifting struggles and compromises; of the politics of welfare, industrial relations and labour markets; and the transformation of post-industrial networked workplaces, this edited collection shows how capitalist workplaces and economies are changing today. The first section explores how European capitalism developed and the different national forms of the struggle between capital and labour for a bigger share of national income. In the second part of the volume, the contributors investigate the institutions that are the building blocks of these different national forms, and how they are changing as labour markets are increasingly shaped by globalisation, feminisation and liberalisation. The final chapters examine how these institutions of capitalism play out in the contemporary workplace – where the most dynamic sectors are based on loose networks and external labour markets and a shifting, uncertain alliance between employers and workers. The authors argue for a new integration of political economy and the sociology of work and organisations.
