Bisphenol A: How the Most Relevant Exposure Sources Contribute to Total Consumer Exposure

Bisphenol A (BPA) is an endocrine disrupting chemical that is found in human urine throughout industrial societies around the globe. Consumer exposure pathways to BPA include packaged food, household dust, air, and dental fillings. To date, information on the relative contribution of the different pathways to total consumer exposure is lacking, but is key for managing substance‐associated risks. We investigated the relative contributions of the pathways known to be most relevant for nine different consumer groups. Our results suggest that the most important pathways for infants and children are the use of polycarbonate (PC) baby bottles and for adults and teenagers the consumption of canned food. Dental surgery can also considerably contribute over a short time directly after the surgery. For infants fed with PC baby bottles with mean dose rates of 0.8 μg/kg_bw/d the highest exposure dose rate was calculated. This dose rate is far below the tolerable daily intake of 50 μg/kg_bw/d. However, it is of the same order of magnitude as recently reported concentrations that caused low‐dose health effects in rodents. We find a pattern of falling exposure levels with rising age that is supported by urinary concentrations of BPA available for selected consumer groups. Similarly, the exposure levels we predict are confirmed by the levels reported in these studies.     

From pillar to post: Women and social work studies in the 21st century

Abstract

A decade or so after the acknowledgement and inclusion of women's issues in mainstream social work courses, we find the circumstances in which such education occurs have changed. The 'third wave' of feminism has revisited the feminist agenda of the 1960s and 1970s; there has been a paradigm shift in what tertiary education is perceived to offer; and global theories have been replaced by post modern interpretations. This article discusses the impact of these changes for social work education drawing on the authors' experiences with the 'Women and Social Work' elective subject in the Bachelor of Social Work Degree at the University of New South Wales, Australia. This elective was popular until the mid 1990s when it failed to attract students. The authors reflect on their experience of teaching the subject and their understanding of current feminism to identify a way forward in the attempt to rekindle student enthusiasm for feminist understandings and provide education which will further the emancipatory project of social work.     

Politics: Butler's Corporeal Politics: Matters of Politicized Abjection

This essay examines the work of Judith Butler in relation to corporeality through an analysis of Bodies that Matter: On the Discursive Limits of Sex and Butler's notion of politicized abjection. Abjection is considered in relation to bodily materiality and proposed as the most promising path for a revamped corporeal politics. Through a reading of two novels, Katherine Dunn's Geek Love and Barbara Gowdy's Mister Sandman, the essay examines how the abject body can function as politically subversive. Throughout, the essay analyses Butler's placing of the material body in a political domain, and argues that she ultimately endorses materiality as potentially disruptive to the symbolic domain of viable bodies. This recasting of matter within her theory is shown as redefining the body as an active agent rather than a passive receptacle for regulatory norms. The essay examines this under-theorized aspect of her work, and illustrates that politicized abjection is as crucial to her philosophy as the notion of gender as performative.     

Epidemic Mycoplasma Pneumoniae Infection at a College for the Deaf

Abstract

An outbreak of Mycoplasma pneumoniae infection affected up to 110 students and employees at a college for deaf students (Gallaudet). After the introduction of M. pneumoniae onto the campus in late August 1977, the disease spread slowly among the students; the last documented case occurred in mid-December. A thorough review of chart records, mail surveys, a dormitory survey, and a three-month surveillance of the student health service provided an intensive look at the epidemiology and clinical spectrum of a mild to moderately severe disease in the epidemic setting. A matched-pair analysis demonstrated a more serious clinical illness among patients with M. pneumoniae than other patients presenting with febrile respiratory illness. Appropriate antimicrobial therapy appeared to suppress a high antibody response to M. pnuemoniae. A follow-up serosurvey one year after this outbreak demonstrated diagnostic titers to M. pneumoniae in 11 of 30 patients with confirmed infection in the original epidemic.     

Drinking Game Participation Among Undergraduate Students Attending National Alcohol Screening Day

Abstract

Objectives, Participants, Methods: Drinking game participation has increased in popularity among college students and is associated with increased alcohol consumption and alcohol-related problems. The current study investigated drinking game participation among 133 undergraduates attending National Alcohol Screening Day (NASD) in April of 2007. Results: A large percentage of the sample reported lifetime (77%) and recent (52%) drinking game participation. Males were more likely to report recent participation and reported higher levels of consumption while playing drinking games. Drinking game participants were more likely to experience a range of alcohol-related problems, and the relationship between drinking game participation and alcohol-related problems was mediated by weekly alcohol consumption. Conclusions: These results suggest that drinking game participation is a risk factor for elevated levels of alcohol consumption and alcohol-related problems. Programs should be developed to educate students about the risks of drinking game participation, and prevention programs like NASD should address drinking games.     

Introduction: “There Is a Person Here”: An Interview with Judith Butler

In this interview, the coeditors, along with other contributors, ask Judith Butler a variety of questions regarding queer theory, gender identities, scientific and legal discourse, bodily abjection, race and class positioning, and political organizing. This range of subject matter suggests not only the breadth of Butler's work, but also its applicability to any number of people, whose relation to theory ranges from highly politicized to politically indifferent. The interview demonstrates the responsiveness of Butler's work to cultural translation and political action.     

Self‐conscious Shyness: Growth during Toddlerhood,Strong Role of Genetics,and No Prediction from Fearful Shyness

Fearful and self‐conscious subtypes of shyness have received little attention in the empirical literature. Study aims included the following: (1) determining whether fearful shyness predicted self‐conscious shyness, (2) describing development of self‐conscious shyness, and (3) examining genetic and environmental contributions to fearful and self‐conscious shyness. Observed self‐conscious shyness was examined at 19, 22, 25, and 28 months in same‐sex twins (MZ = 102, DZ = 111, missing zygosity = 3 pairs). Self‐conscious shyness increased across toddlerhood, but onset was earlier than predicted by theory. Fearful shyness (observed [6 and 12 months] and parents’ reports [12 and 22 months]) was not predictive of self‐conscious shyness. Independent genetic factors made strong contributions to parent‐reported (but not observed) fearful shyness (additive genetic influence = .69 and .72 at 12 and 22 months, respectively) and self‐conscious shyness (additive genetic influence = .90 for the growth model intercept). Results encourage future investigation of patterns of change and inter‐relations in shyness subtypes.     

PREDICTORS OF WOMEN'S RETURN TO VIOLENT PARTNERS

The study aimed to prospectively assess the variables which predict women's intention to return and actual return to violent partners. A questionnaire was developed and administered to 78 women who were taking refuge in a women's shelter after leaving a violent partner. After a two month period it was determined whether or not the women had returned to their partner. Intention to return was significantly predicted by the frequency and severity of violence, the age of the woman's youngest child, her belief the partner had changed, subjective norms and external locus of control. Actual return was predicted by the intention to return to partner, number of times a women had previously left her partner, commitment to relationship, subjective norms and allocation of responsibility for violence. It was argued that therapeutic interventions that address the attitudinal predictors of intention to return or actual return could aid some women and their children to remain away from a violent living situation.     

Maternal and Child Anxiety: Do Attachment Beliefs or Children's Perceptions of Maternal Control Mediate Their Association?

This study tested a model of the association between maternal and child anxiety that views mother and child attachment beliefs and children's perceptions of maternal control as mediators of the association. The study was conducted with mothers and their children aged 6 to 17 (N = 88). Maternal anxiety was significantly associated with child anxiety and maternal anxious attachment beliefs, whereas child anxiety was associated with maternal anxious attachment beliefs, child insecure attachment beliefs, and children's perceptions of maternal control. Maternal anxious attachment beliefs mediated the association between maternal and child anxiety; however, child attachment beliefs and children's perceptions of maternal control did not. The influence of age and gender is also addressed. The findings are discussed in terms of elucidating the role of attachment beliefs and children's perceptions of maternal control on the association between maternal and child anxiety.     

Border Lines: Indigenous Peoples in Genocide Studies*

L'histoire des peuples autochtones ne figure pas parmi les sujets qui sont traités dans la recherche comparée en génocide. Les auteures examinent l'approche conceptuelle qui a conduit à cette lacune en s'attardant à la terminologie employée et à la distinction qu'impose la typologie du génocide entre génocide idéologique et génocide provoqué par l'expansion d'un groupe aux dépens d'un autre, et en soulignant l'importance qui est rattachée dans cette même typologie à la logique qui motive les régimes coupables de génocide. On examine également la relation qui existe entre génocide des peuples autochtones et ceux des autres peuples, ceci en relation avec trois critères d'analyse, soit la réaction des persécutés, le processus de guérison et la quête de justice. À la suite de cet examen, on démontre qu'une approche plus globale dans l'étude comparée du génocide, approche qui reconnaîtrait l'enver-gure des génocides des peuples autochtones, serait à l'avantage des chercheurs. Enfin, les auteures font remarquer que l'approche foncièrement européenne dans la recherche en génocide a pour effet de circonscrire le débat. The experiences of indigenous peoples have been left outside the framework of comparative genocide research. We first discuss conceptual reasons for this omission, focussing on the role of genocide definitions, ideological vs. developmental distinctions in genocide typologies, and the emphasis in genocide typologies on the motivations of perpetrators. We then illustrate the relation between indigenous genocides and other genocides by examining three important foci of genocide studies: responses, healing and justice. From these comparisons and contrasts, we conclude that a broader comparative approach that acknowledges the importance of indigenous genocides would contribute significantly to genocide studies. Finally, we note that adherence to European world views in genocide studies limits the potential for constructive analysis.
