Impact of gene variants on sex-specific regulation of human Scavenger receptor class B type 1 (SR-BI) expression in liver and association with lipid levels in a population-based study.

BACKGROUND: Several studies have noted that genetic variants of SCARB1, a lipoprotein receptor involved in reverse cholesterol transport, are associated with serum lipid levels in a sex-dependent fashion. However, the mechanism underlying this gene by sex interaction has not been explored. METHODS: We utilized both epidemiological and molecular methods to study how estrogen and gene variants interact to influence SCARB1 expression and lipid levels. Interaction between 35 SCARB1 haplotype-tagged polymorphisms and endogenous estradiol levels was assessed in 498 postmenopausal Caucasian women from the population-based Rancho Bernardo Study. We further examined associated variants with overall and SCARB1 splice variant (SR-BI and SR-BII) expression in 91 human liver tissues using quantitative real-time PCR. RESULTS: Several variants on a haplotype block spanning intron 11 to intron 12 of SCARB1 showed significant gene by estradiol interaction affecting serum lipid levels, the strongest for rs838895 with HDL-cholesterol (p=9.2x10(-4)) and triglycerides (p=1.3x10(-3)) and the triglyceride:HDL cholesterol ratio (p=2.7x10(-4)). These same variants were associated with expression of the SR-BI isoform in a sex-specific fashion, with the strongest association found among liver tissue from 52 young women<45 years old (p=0.002). CONCLUSIONS: Estrogen and SCARB1 genotype may act synergistically to regulate expression of SCARB1 isoforms and impact serum levels of HDL cholesterol and triglycerides. This work highlights the importance of considering sex-dependent effects of gene variants on serum lipid levels.

Does predation control adult sex ratios and longevities in marine pelagic copepods?

We assess the causes of adult sex ratio skew in marine pelagic copepods by examining changes in these ratios between the juveniles and adults, sexual differences in juvenile stage durations, and mortality rates of adults in the field and laboratory (when free from predators). In the field, late copepodite stages (CIV and CV) commonly have sex ratios that are either not significantly different from equity (1 : 1), or slightly male biased. By contrast, in adults, these ratios are commonly significantly biased toward female dominance. Sex ratio skews are therefore primarily attributable to processes in adults. Members of the non-Diaptomoidea have especially skewed adult ratios; in the members Oithonidae and Clausocalanidae this is not generated from differences between male and female adult physiological longevity (i.e., laboratory longevity when free of predators). In the genera Acartia, Oithona, and Pseudocalanus, we estimate that predation mortality contributed ≥ 69% of the field mortality rate in adult males, whereas in Acartia, Oithona, and Calanus adult females, this is ≥ 36%.We conclude that (1) adult sex ratio skew in pelagic copepods is primarily due to differential mortality of the sexes in the adult stage and not in juveniles, (2) mortality rates of adult Acartia, Pseudocalanus, and Oithona are dominated by predation mortality rather than physiological longevity (except under extreme food limitation), and (3) in Pseudocalanus and Oithona, elevated mortality rates in adult males to females is predominantly due to higher predation on males. Our work demonstrates that we now need to develop a more comprehensive understanding of the importance of feeding preferences in predators. Continue reading full article

Female-biased sex ratios in marine pelagic copepods: comment on Gusmao et al

Gusmão et al. (2013; Mar Ecol Prog Ser 482:279-298) review causes of sex ratio skew in pelagic copepods and in doing so repeatedly dispute the paper of Hirst et al. (2010) ‘Does predation control adult sex ratios and longevities in marine pelagic copepods?’ Here we respond to some important errors in their citation of our paper and briefly highlight where future work is needed in order to attribute the causes of strong sex ratio skew seen in some copepod families.

A survey of sidedness in Northern Irish schoolchildren: The interaction of sex, age, and task

The study examined lateral preference in use of hands, feet, eyes, and ears in a group of nearly 5000 schoolchildren in Northern Ireland. Performance tests were carried out by student teachers during their school-based work in 2002 and data were submitted on-line. Six tasks were used-writing, throwing a ball, kicking a ball, hopping, listening to quiet sounds, and looking through a cardboard tube. There was right bias in every task but the extent of it differed between tasks. Males were generally less right biased than females, and younger children less than older ones; for hearing, the changes with age were markedly different in the two sexes, with females showing a strong increase in right bias but males showing none. These observational results do little to illuminate the reasons for the patterns observed.

Work-place social capital and smoking cessation: The Finnish Public Sector Study

AIMS:
To examine whether high social capital at work is associated with an increased likelihood of smoking cessation in baseline smokers.
DESIGN:
Prospective cohort study.
SETTING:
Finland.
PARTICIPANTS:
A total of 4853 employees who reported to be smokers in the baseline survey in 2000-2002 (response rate 68%) and responded to a follow-up survey on smoking status in 2004-2005 (response rate 77%).
MEASUREMENTS:
Work-place social capital was assessed using a validated and psychometrically tested eight-item measure. Control variables included sex, age, socio-economic position, marital status, place of work, heavy drinking, physical activity, body mass index and physician-diagnosed depression.
FINDINGS:
In multi-level logistic regression models adjusted for all the covariates, the odds for being a non-smoker at follow-up were 1.26 [95% confidence interval (CI)=1.03-1.55] times higher for baseline smokers who reported high individual-level social capital than for their counterparts with low social capital. In an analysis stratified by socio-economic position, a significant association between individual-level social capital and smoking cessation was observed in the high socio-economic group [odds ratio (OR) (95% CI)=1.63 (1.01-2.63)], but not in intermediate [(OR=1.10 (0.83-1.47)] or low socio-economic groups [(OR=1.28 (0.86-1.91)]. Work unit-level social capital was not associated with smoking cessation.
CONCLUSIONS:
If the observed associations are causal, these findings suggest that high perceived social capital at work may facilitate smoking cessation among smokers in higher-status jobs.

Relationship between work stress and body mass index among 45,810 female and male employees

Objective: The proportion of overweight and obese people has grown rapidly, and obesity has now been widely recognized as an important public health problem. At the came time, stress has increased in working life. The 2 problems could be connected if work stress promotes unhealthy eating habits and sedentary behavior and thereby contributes to weight gain. This study explored the association between work stress and body mass index (BMI; kg/m(2)). Methods: We used cross-sectional questionnaire data obtained from 45,810 female and male employees participating in the ongoing Finnish Public Sector Cohort Study. We constructed individual-level scores, as well as occupational- and organizational-level aggregated scores for work stress, as indicated by the demand/control model and the effort-reward imbalance model. Linear regression analyses were stratified by sex and socioeconomic status (SES) and adjusted for age, marital status, job contract, smoking, alcohol consumption, physical activity, and negative affectivity. Results: The results with the aggregated scores showed that lower job control, higher job strain, and higher effort-reward imbalance were associated with a higher BMI. In men, lower job demands were also associated with a higher BMI. These associations were not accounted for by SES, although an additional adjustment for SES attenuated the associations. The results obtained with the individual-level scores were in the same direction, but the relationships were weaker than those obtained with the aggregated scores. Conclusions: This study shows a weak association between work stress and BMI.

'Grooming' and the Sexual Abuse of Children: Implications for Sex Offender Assessment, Treatment and Management

'Grooming' has been termed 'a ubiquitous feature of the sexual abuse of children' (Thornton, 2003: 144). Despite the prominence of the term in contemporary discourses on sexual offending against children, it is a term that is insufficiently understood in the psychological, sociological, criminological or legal literature. Most recently, the term has been used in two primary offending contexts - on-line grooming and abuse by strangers, and institutional grooming and abuse by those in positions of trust. This article argues, however, that grooming and its role in child sexual abuse is a multi-faceted phenomenon and much more complex than has been highlighted previously. While there are a number of typologies of grooming, this article concentrates on those which may be most relevant for treatment and management contexts - 'peer-to-peer grooming' and 'institutional grooming.' Drawing on extensive fieldwork with professionals who work in the fields of child protection or victim support, and sex offender assessment, treatment or management across the United Kingdom and the Republic of Ireland, the aim of this article is two-fold: (i) to deconstruct the term grooming and examine its actual role in the onset of sexual offending against children; and (ii) to draw out the implications of these complexities for policy and practice, chiefly in terms of treatment and prevention.

Gendered Violence and International Human Rights: Thinking Non-Discrimination Beyond the Sex Binary

The concept of non-discrimination has been central in the feminist challenge to gendered violence within international human rights law. This article critically explores non-discrimination and the challenge it seeks to pose to gendered violence through the work of Judith Butler. Drawing upon Butler’s critique of heteronormative sex/gender, the article utilises an understanding of gendered violence as effected by the restrictive scripts of sex/gender within heteronormativity to illustrate how the development of non-discrimination within international human rights law renders it ineffective to challenge gendered violence due to its own commitments to binarised and asymmetrical sex/gender. However, the article also seeks to encourage a reworking of non-discrimination beyond the heteronormative sex binary through employing Butler’s concept of cultural translation. Analysis via the lens of cultural translation reveals the fluidity of non-discrimination as a universal concept and offers new possibilities for feminist engagement with universal human rights.

Associations between near work, outdoor activity, and myopia among adolescent students in rural China: the Xichang Pediatric Refractive Error Study report no. 2.

OBJECTIVE:

To study the associations between near work, outdoor activity, and myopia among children attending secondary school in rural China.

METHODS:

Among a random cluster sample of 1892 children in Xichang, China, subjects with an uncorrected acuity of 6/12 or less in either eye (n = 984) and a 25% sample of children with normal vision (n = 248) underwent measurement of refractive error. Subjects were administered a questionnaire on parental education, time spent outdoors, and weekly time spent engaged in and preferred working distance for a variety of near-work activities.

RESULTS:

Among 1232 children with refraction data, 998 (81.0%) completed the near-work survey. Their mean age was 14.6 years (SD, 0.8 years), 55.6% were girls, and 83.1% had myopia of -0.5 diopters or less (more myopia) in both eyes. Time and diopter-hours spent on near activities did not differ between children with and without myopia. In regression models, time spent on near activities and time outdoors were unassociated with myopia, adjusting for age, sex, and parental education.

CONCLUSIONS:

These and other recent results raise some doubts about the association between near work and myopia. Additional efforts to identify other environmental factors associated with myopia risk and that may be amenable to intervention are warranted.

Radical interiors: Cindy Sherman's ‘Sex pictures’ and Kathy Acker's 'My mother: demonology'

In 1989, the American visual artist Cindy Sherman produced her ‘Sex Pictures’, a number of photographic images of two medical mannequins whose bodies had been dismembered and reconstructed to form abstract configurations that alluded to pornographic poses. Sherman's series was a response to the National Endowment for the Arts controversy, in which American artists such as Andres Serrano and the late Robert Mapplethorpe, whose work was considered obscene by the Republican Congress, were censored. Many artists in the culture-war period had their grants rescinded. The American avant-garde writer Kathy Acker published My Mother: Demonology in 1993. A prominent concern of Acker's in the work is what she termed her ‘writing freedom’ in a climate of cultural expurgation by the Republican elite. In particular, Acker was worried that she was ‘internalizing certain censorships’. This article addresses Sherman's and Acker's work in a comparative context to explore, through the theoretical work of Julia Kristeva, the ways in which their responses to a climate of political censorship can be read as forms of intimate revolt. Kristeva's notion of ejection—the act of placing something beyond the scope of the possible—transpires as ‘a condition of art's creation’ in Sherman's and Acker's work. Acker and Sherman use the pornographic reference in their work to disrupt and dislocate the narrative and image from convention in order to de-eroticize the body, against heteronormativity's terms, and empower the female sex organs. Eversion—that is, in Sherman's and Acker's works, the act of turning the institutional and maternal body inside out—emerges as a mode of resistance to the danger of the writer and the artist internalizing cultural restrictions. The everted body creates a site of radical interiority which becomes the (impossible) site for the radical (re-)embodiment of the feminine subject.

Sex chromosome translocation and speciation : a Drosophila genetic model

Although exceptions may be readily identified, two generalizations concerning genetic differences among species may be drawn from the available allozyme and chromosome data. First, structural gene differences among species vary widely. In many cases, species pairs do not differ more than intraspecific populations. This suggests that either very few or no gene substitutions are required to produce barriers to reproduction (Avise 1976). Second, chromosome form and/or number differs among even closely related species (White 1963; 1978; Fredga 1977; Wright 1970). Many of the observed chromosomal differences involve translocational rearrangements; these produce severe fitness depression in heterozygotes and were, thus, long considered unlikely candidates for the fixation required of genetic changes leading to speciation (Wright 1977). Nonetheless, the fact that species differences are frequently translocational argues convincingly for their fixation despite prejudices to the contrary. Haldane's rule states that in the F of interspecific crosses, the heterogametic sex is absent or sterile in the preponderance of cases (Haldane 1932). This rule definitely applies in the genus Dr°sophila (Ehrman 1962). Sex chromosome translocations do not impose a fitness depression as severe as that imposed by autosomal translocations, and X-Y translocations may account for Haldane's rule (Haldane 1932). Consequently a study of the fit ness parameters of an X·yL and a yS chromosome in Drosophila melanogaster populations was initiated by Tracey (1972). Preliminary results suggested that x.yL//YSmales enjoyed a mating advantage with X·yL//X·yL females, that this advantage was frequency dependent, that the translocation produced sexual isolation and that interactions between the yL, yS and a yellow marker contributed to the observed isolation (Tracey and Espinet 1976; Espinet and Tracey 1976). Encouraged by the results of these prelimimary studies, further experiments were performed to clarify the genetic nature of the observed sexual isolation, S the reality of the y frequency dependent fitness .and the behavioural changes, if any, produced by the translocation. The results of this work are reported herein. Although the marker genes used in earlier studies, sparkling poliert an d yellow have both been found to affect activity,but only yellow effects asymmetric sexual isolation. In addition yellow effects isolation through an interaction with the T(X-y) chromosomes, yS also effects isolation, and translocational strains are isolated from those of normal karyotype in the absence of marker gene differences. When yS chromosomes are in competition with y chromosomes on an X.yL background, yS males are at a distinct advantage only when their frequency is less than 97%. The sex chromosome translocation alters the normal courtship pattern by the incorporation of circling between vibration and licking in the male repertoire. Finally a model of speciation base on the fixation of this sex chromosome translocation in a geographically isolated gene pool is proposed.

Dramatizing whoredom : prostitution in the work of Tennessee Williams

Cette thèse explore le leitmotiv de la prostitution dans l’oeuvre de Tennessee Williams et soutient que la plupart des personnages de Williams sont engagés dans une forme de prostitution ou une autre. En effectuant une analyse formaliste des textes de Williams qui illustrent toute forme de prostitution, avec une attention particulière à quatre grandes pièces, A Streetcar Named Desire (1947), Cat on a Hot Tin Roof (1955), Suddenly Last Summer (1958) et Sweet Bird of Youth (1959), cette présente étude fait valoir que le dramaturge utilise un mode de fiction—le gothique—en lien avec une pratique transgressive—la prostitution—pour relier les classes sociales et troubler les catégories de prostitution. Ce faisant, Williams offre une vision plus représentative et nuancée de la prostitution. Théoriquement, cette thèse repose sur des oeuvres critiques portant sur le genre, la sexualité et l'histoire de Michel Foucault, David Savran, et Michael Paller afin de situer la dramaturgie de Williams dans le contexte historique et culturel des années 1940 et 1950. La première partie de cette thèse (chapitres un et deux) fournit de nombreuses informations autobiographiques et biographiques qui expliquent pourquoi la prostitution est devenue le thème de prédilection pour Williams. Cette section met l’accent sur sa préoccupation constante à l’égard de sa prostitution artistique (en prostituant son art pour le succès commercial) et sexuelle (en payant pour des prostitués). Cette partie présente également un inventaire détaillé des prostituté(e)s, que je divise en trois catégories: 1) la prostitution des enfants, 2) la prostitution masculine et 3) la prostitution féminine. La deuxième partie de cette étude, composée des chapitres trois et quatre, identifie les personnages de Williams qui s’engagent dans une forme de prostitution morale. Ce groupe comprend ceux qui tirent directement profit de la prostitution des autres ainsi que ceux qui se marient uniquement pour un gain financier ou une promotion sociale ou les deux. L’oeuvre de Williams résiste la représentation stéréotypée de la prostituée en littérature comme étant uniquement de sexe féminin ou provenant des classes sociales défavorisées ou les deux. La prostituée de Williams n’est ni une figure romantique ni une rebelle menaçant la société. Cette thèse conclut qu’en représentant des enfants prostitués, des femmes de rue, des prostitués de sexe masculin, des souteneurs, des proxénètes, des propriétaires de bordels, des leaders corrompus et des personnes qui se prostituent en concluant des mariages de convenance, Williams a effectivement et incontestablement dramatisé la prostitution sous toutes ses formes.

AIDS, mobility and commercial sex in Ethiopia: Implications for policy

Since the emergence of the AIDS pandemic in sub-Saharan Africa, male mobility has been highlighted as one of the reasons for the spread of the disease with men employing the services of commercial sex workers while away from home. However, sex workers' mobility and the implications of this for their access to prevention services, has largely been ignored. This paper, based on multi-method qualitative research with 60 young sex workers in two Ethiopian towns, reveals that sex workers are highly mobile, moving in order to attract a wider or different client base, for adventure and to conceal illnesses which might be associated with AIDS. In addition, sex workers are affected by restrictions on their movements, with girls working in bars and red-light areas having little free time to access projects. This paper advocates that policy approaches need to take account of this mobility in three ways: first, by exploring ways for girls to access information and maintain contact with support structures while moving between places of work; second, by building the capacity of sex workers to take greater control over decision-making in their day-to-day lives and third, by developing outreach strategies for taking services into bars and red-light areas.

Dancing, skating and sex: action and text in the digital age

This paper explores the relationship between discourse and action in practices involved in making and consuming texts. Texts are produced through the process of ‘entextualization’ in which strips of action and discourse are extracted from their original contexts and recontextualized into other situations. Different technologies for turning actions into texts affect the kinds of social actions and social identities that are made possible both at moments of entextualization and at future moments of recontextualization. In particular, I focus on how digital technologies affect the practices and participation structures around entextualization. Digital photography and video have had a profound effect on social practices and relationships around the making of texts. Specifically, they have made processes of entextualization more immediate, more contingent and more communal. Implications of these features of digital text making are discussed in light of previous work on literacy and orality.
