Speaking of gender: teachers' metaphorical constructs of male and female students

This article explores the images and metaphors that teachers use when speaking of their relations with students and examines how these images work to call into play particular constructs of gender relations. Of specific interest is the way teachers use binaries of open/closed, in control/out of control and maturity/immaturity to make sense of feminine and masculine conduct respectively. It is argued that such binary differentiations work not only as descriptors of `truths' concerning student-teacher relations, but also as means of constituting and normalizing particular forms of gender  relations. Implications of such metaphorical constructions for gender reform within schools are considered.

Assessment of 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D3 concentrations in male and female multiple sclerosis patients and control volunteers

Populations with insufficient ultraviolet exposure and who consume diets low in vitamin D have low vitamin D status (plasma 25-hydroxyvitamin D (25(OH)D) concentrations) and a reported higher incidence of multiple sclerosis (MS). The active form of vitamin D, 1,25-dihydroxyvitamin D₃ (1,25(OH)₂D₃), is an effective anti-inflammatory molecule. No research to date has assessed 1,25(OH)₂D₃ concentrations in individuals with MS. In this study, plasma concentrations of 25(OH)D, 1,25(OH)₂D ₃ and parathyroid hormone (PTH) were measured in 29 individuals with MS and 22 age- and sex-matched control volunteers. There were no significant differences in plasma PTH, 25(OH)D and 1,25(OH)₂D₃ concentrations between individuals with MS and control volunteers. Women with MS had significantly higher 25(OH)D and 1,25(OH)₂D₃ concentrations than men with MS (79.1 ±45.4 versus 50.2±15.3 nmol/L, P=0.019 and 103.8± 36.8 versus 70.4±28.7 pmol/L, P=0.019, respectively). There was a significant positive correlation between 25(OH)D and 1,25(OH)₂D ₃ concentrations in all subjects (r=0.564, P=0.000), but secondary analysis revealed that the correlation was driven by women with MS (r=0.677, P= 0.001). Significant sex differences in vitamin D metabolism were observed and were most marked in individuals with MS, suggesting that vitamin D requirements may differ between the sexes, as well as by underlying disease state.

Sentencing of male and female child sex offenders : Australian study

Research suggests that, in line with the chivalry hypothesis of female offending, a range of mitigatory factors such as mental health problems, substance abuse, and personal experiences of abuse are brought into play when women who offend against children are brought to trial. This is reflected in sentencing comments made by judges and in the sanctions imposed on the offenders, and as a result female offenders are treated differently to male offenders. The current study investigated this in an Australian context. Seven cases of female-perpetrated child sexual abuse were identified over a 6-year period through the Austlii database. Seven cases of male-perpetrated child sex abuse matched as far as possible to these were identified. Court transcripts were then located, and sentencing comments and sanctions imposed were analysed. All offenders were sentenced to imprisonment, but in general the women were more likely than the men to receive less jail time and lower non-parole periods because their personal backgrounds or situation at the time of the offending (i.e., difficulties with intimate relationship, male dependence issues, depression, loneliness and anger) were perceived as worthy of sympathy, and they were considered as likely to be rehabilitated. Further investigations are needed to support these findings.

Malaysian and Australian male and female middle managers : a cross-cultural comparison of workplace attitudes, aspirations for promotion, and self-rated leadership styles

This paper outlines the rise of women in management worldwide, and considers why so few women achieve senior or executive management positions. This slow advance of women into senior roles is unexpected given that the changes in organisations today are believed to require more ‘feminine leadership’. A decrease in the emphasis on masculine characteristics for managers is reported, and a requirement that more ‘feminine leadership’ needs to be adopted by organisations in order to ensure their survival in the future (Powell, Butterfield & Parent, 2002, p.189). Recent empirical research reports that there are differences in leadership style between male and female managers, and the findings suggest that women exhibit more transformational leadership than their male counterparts, with this style being strongly equated with effective leadership (Eagly, Johannesen-Schmidt, van Engen, 2003). However, these findings are based on western research, and it may be that cross cultural research will yield a different picture (House, Hanges, Javidan, Dorfman, & Gupta, 2004). Leadership and leadership styles may be conceptualised differently in a more paternalistic society. To explore this possibility, a cross cultural study was conducted in Malaysia and Australia. It is hypothesised that countries that are paternalistic in cultural values will exhibit a stronger constraint on women in management roles, which may impact on workplace attitudes, aspirations for promotion and style of leadership exhibited. Therefore, it is possible that the career advancement of women may be more problematic for Malaysian managerial women than their Australian counterparts. Results from an initial pilot study in Malaysia and Australia are outlined, and highlight some interesting similarities and differences to what are reported in the western literature.

Male and female effects on fertilization success and offspring viability in the Peron's tree frog, Litoria peronii

There is increasing theoretical and empirical evidence that genetic compatibility among partners is an important determinant of fertilization success and offspring viability. In amphibians, females often actively choose partners from among a variety of males and polyandry is common. Genetic compatibility among partners may therefore be an important determinant of fertilization success and offspring viability in some amphibians. Amphibians also show some of the highest levels of genetic differentiation among neighbouring populations known in vertebrates, and as such, populations may have evolved different co-adapted gene complexes. This means that offspring from among-population crosses may have reduced fitness. It is therefore essential to understand to what extent crossings between and within populations may interfere with successful fertilization and offspring viability. Here, we test whether crossing individuals within and between two different populations of the Australian Peron's tree frog (Litoria peronii) using artificial fertilizations affect fertilization success and offspring viability. Fertilization success per se is strongly influenced by male identity, which is likely to depend at least to some extent on the experimental procedure (e.g. resulting in variation in sperm number per ejaculate), whereas there was no fertilization effect of female identity. More importantly, male and female identity, independently of each other, explained significant variation in offspring viability, whereas no such effect could be linked to population of origin. Thus, our experiments suggest that crossing populations may not always be the most significant factor affecting fertilization success or offspring viability, but may be more influenced by the genetic quality or the genetic compatibility of partners.

Victimological and cognitive scripting study of adult male and female rape

From this exploratory study it appears that the experience of adult rape has many similarities for men and women, but there are additional factors which may account for the adjustment differences and difficulties for and of men.

Accumulated oxygen deficit measurements during and after high-intensity exercise in trained male and female adolescents

The purpose of this study was to compare accumulated oxygen deficits and markers of anaerobic metabolism [plasma ammonia (NH3) and lactate (La⁻) concentrations] in anaerobically trained male [n = 8, age 14.8 (0.5) years; maximal oxygen consumption V˙O2 max 61.74 (2.23) ml ·  kg⁻¹ · min⁻¹] and female [n = 8, age 14.5 (0.2) years; V˙O2 max 49.62 (3.52) ml · kg⁻¹ · min⁻¹] adolescents. The exercise protocol consisted of runs to exhaustion at speeds predicted to represent 120% and 130% of V˙O2 max. Arterialised blood samples were obtained from a pre-warmed hand via a catheter inserted into a forearm vein. Samples were taken at rest and after 1, 3, 5, 7, 10, 15 and 20 min of recovery. The high-intensity exercise resulted in mean accumulated oxygen deficits that were less (P < 0.05) in females (52.3 ml · kg⁻¹) than in males (68.6 ml · kg⁻¹). Lower (P < 0.05) plasma concentrations of NH3 and La⁻¹, and a higher pH were evident in females compared with males during various stages of the 20-min recovery period. The increase in anaerobic performance in the male adolescent athletes when compared with their female counterparts was associated with an increased plasma concentration of selected plasma and blood metabolites. The observed results may reflect well-established differences between the sexes in the morphology and metabolic power of muscle.

Conservation hotspots : implications of intense spatial area use by breeding male and female loggerheads at the Mediterranean’s largest rookery

The implementation of appropriate protection measures for endangered species in protected areas requires knowledge of their fine-scale habitat use. In May and June of 2006 and 2007, we used GPS loggers (some linked to the Argos system) and a conventional Argos transmitter to track male and female loggerhead turtles Caretta caretta in the vicinity of the breeding area of Laganas Bay within the National Marine Park of Zakynthos, Greece. We obtained (1) 9681 useable locations (mean: 1383 locations ind.–1; range: 519 to 2198 locations) from Tracktag GPS loggers attached to 7 females for a mean duration of 34 d (range: 17 to 52 d); (2) 1245 useable locations (mean: 311 locations ind.–1; range: 38 to 1110 locations) from 4 males fitted with Fastloc Argos tags for a mean duration of 29 d (range: 3 to 51 d) and (3) 100 locations from 1 male fitted with a conventional Argos satellite tag tracked for 128 d. GPS data indicated that before the onset of nesting, both males and females primarily used an area within 500 m of the shore along a core 9 km stretch of coastline, where existing protective legislation requires strengthening. Our observations suggest that a 76.7% female-biased operational sex ratio, measured previously from in-water surveys, may represent a realistic sex ratio estimate in the period before nesting starts. In the first month following the onset of nesting, female spatial distribution remained similar, whereas most males departed for distant areas presumably to forage. Our study provides quantitative evidence of the need to improve the management planning and conservation measures to protect sea turtles in a coastal breeding area, and new insights on male turtle migration.

Do female and male employees in Iran experience similar work-family interference, job and life satisfaction?

This study aims at examining gender differences in the experience of work–family interference and perceived job–life satisfaction in a group of Iranian employees. The participants in the study consist of 387 Iranian male and female employees from a variety of organizations. The results of t tests and multiple regression analysis using EQS 6.1 support the hypothesis that Iranian male and female employees experience similar interference in their work–family domains although they spend different numbers of hours in the workplace. The findings also show that whereas work-to-family interference has significant and negative effects on job–life satisfaction among male employees, for female employees, working hours and family-to-work interference had even more significant and negative effects on their job–ife satisfaction. Implications are discussed and recommendations made regarding future research and interventions in this area.
