Intervention programmes to recruit female computing students : why do the programme champions do it?

This paper looks at intervention programmes to improve the representation of female students in computing education and the computer industry, A multiple case study methodology was used to look at major intervention programmes conducted in Australia. One aspect of the research focused on the programme champions; those women from the computing industry, those working within government organisations and those in academia who instigated the programmes. The success of these intervention programmes appears to have been highly dependent upon not only the design of the programme but on the involvement of these strong individuals who were passionate and worked tirelessly to ensure the programme's success. This paper provides an opportunity for the voices of these women to be heard. It describes the champions' own initial involvement with computing which frequently motivated and inspired them to conduct such programmes. The research found that when these types of intervention programmes were conducted by academic staff the work was undervalued compared to when the activities were conducted by staff in industry or in government. The academic environment was often not supportive of academics who conducted intervention programmes for female students.

A culturally appropriate diet and lifestyle intervention can successfully treat the components of metabolic syndrome in female Pakistani immigrants residing in Melbourne, Australia

This study was designed to test the effectiveness of a culturally appropriate diet and lifestyle intervention to treat metabolic syndrome in female Pakistani immigrants residing in Melbourne, Australia. Forty Pakistani women with metabolic syndrome (aged 20-50 years) completed a 12-week culturally appropriate diet and exercise program. Results indicate that, before intervention, participants were sedentary, taking 4000 ± 22.6 steps per day, and had an obese-classified body mass index (BMI) of 29.2 ± 0.46 kg/m2 (BMI was categorized in accordance with guidelines specifically designed for Asians) and high waist circumference of 132 ± 25.95 cm. Participants were hypertensive (systolic, 135 ± 1.3 mm Hg; diastolic, 86 ± 0.68 mm Hg), were dyslipidemic (total cholesterol, 6.8 ± 0.15 mmol/L; triglycerides, 2.9 ± 0.09 mmol/L), and had elevated blood glucose (6.4 ± 0.33 mmol/L) and fasting blood insulin (45 ± 6.3 μU/mL) levels. After the 12-week culturally appropriate intervention, activity increased (8600 ± 596.7 steps per day, P < .05); and BMI (27.8 ± 0.45 kg/m2), blood pressure (systolic, 125 ± 1.4 mm Hg; diastolic, 80 ± 0.6 mm Hg), cholesterol (5.5 ± 0.1 mmol/L), blood glucose (5.9 ± 0.33 mmol/L), and blood insulin (24.14 ± 1.8 μU/mL) levels were all significantly reduced (P < .05). This study revealed that the Pakistani female migrants who had metabolic syndrome and its components can successfully be treated via a culturally appropriate diet and lifestyle intervention. The success of the current program raises the possibility that other high-risk ethnic groups can also be treated with a culturally appropriate program.

Predicting female depression across puberty : a two-nation longitudinal study

Objective: To prospectively examine the relation between pubertal stage and the onset and course of depressive symptoms.

Method: The design was a three-wave longitudinal study of health and social development using statewide community samples in Washington, United States, and Victoria, Australia. Approximately 5,769 students initially ages 10 to 15 years were assessed for depressive symptoms with the Short Mood and Feelings Questionnaire. Pubertal status was assessed using a self-report version of the Pubertal Development Scale.

Results: Advancing pubertal stage carried higher risks for depressive symptoms in female subjects in all of the three study waves. The pubertal rise in female depressive symptoms was due to both higher risk for incident cases and an even greater effect on risks for persistence of depressive symptoms. Report of poor emotional control 12 months earlier carried a twofold higher risk for incident depressive symptoms and largely explained the pubertal rise in female incident cases. High family conflict and severity of bullying also predicted persistence of depressive symptoms. Preexisting depressive symptoms were not associated with later increases in the rate of pubertal transition.

Conclusions: Advancing pubertal stage carries risks for both the onset and persistence of depressive symptoms in females. Social adversity around puberty predicts the persistence of symptoms but does not account for a pubertal rise in female depression. A report of poor emotional control may be a useful marker of girls at risk for depressive symptoms and as a target for preventive intervention.

Habitat selection by female Australian fur seals (Arctocephalus pusillus doriferus)

1. Numerous studies have determined the foraging areas of marine apex predators and investigated their relationship to oceanographic features. Most of these, however, have concentrated on surface-feeding seabirds or epipelagic-foraging marine mammals and there is little information on habitat selection in benthic divers.

2. Satellite telemetry was used during the winters of 2001-2003 to determine the foraging areas of 48 female Australian fur seals (Arctocephalus pusillus doriferus) from four breeding sites in northern Bass Strait whose colonies together represent > 80% of the total species population.

3. All individuals foraged over the shallow continental shelf of Bass Strait supporting earlier studies that suggested the species is an exclusively benthic forager. Individual females showed a high degree of foraging site-fidelity and several foraging 'hot spot' areas could be identified.

4. Analysis of habitat use indicated that individuals selected areas with depths of 60-80 m significantly more (λ = 0.216, P<0.001) than any other bathymetric class. There was also evidence for foraging areas being influenced by SST, with individuals selecting regions of 16.0-16.8 C SST (λ = 0.008, P<0.01), but not surface chlorophyll-a concentration (P> 0.05).

5. Temporal analysis of at-sea movements indicated, due to their primarily benthic foraging mode, the areas frequented by female Australian fur seals did not overlap substantially with areas targeted by commercial fisheries. An exception to this was in far eastern Bass Strait where the Otter Trawl component of the Commonwealth Trawl Sector is highly active over the continental shelf and encompasses the areas frequented by females from The Skerries colony.

Age-related changes in ovarian characteristices, plasma sex steroids and fertility during pubertal development in captive female Murray cod Maccullochella peelii peelii

Age-related changes in ovarian development characteristics and plasma sex steroids in female Murray cod were examined throughout their second, third and fourth years of life to better understand the physiological and endocrine processes associated with puberty in this species in captivity. Spawning performance of 2+ and 3+ year old females was also assessed to identify ontogenetic differences in egg fertility. Puberty was acquired in 38% of 1+ year old females and 100% of age 2+ females. By age 3+, all females had developed full (adult) reproductive function. Ovarian development in pubertal fish was characterised by a rapid transition between cortical alveoli and lipid droplet oogenic phases, coinciding with significantly lower plasma 17β-oestradiol in age 2+ females (p < 0.05). Mean mature oocyte diameter (2.44 mm), post-fertilisation viability (30.80%) and hatchability (0.99%) of eggs from age 2+ females were significantly reduced relative to age 3+ adults (2.81 mm, 84.89% and 23.58%, respectively). Ovaries of pubertal Murray cod exhibited both vitellogenic and ovulatory capacities, yet functional abnormalities during secondary oocyte growth are likely to have contributed to poor egg fertility and consequently, evaluations of age-at-first maturity based on the presence of advanced ovarian stages may overestimate the reproductive potential of younger broodstock populations.

Rogue men and predatory women : female fan's perception of Australian footballers' sexual conduct

The 2004 Australian Football League and National Rugby League seasons started amidst claims made by women about players behaving inappropriately towards them. A raft of allegations surfaced in the media, prompting nationwide debate on the issue of sportsmen and violence. While sport sociologists have made important inroads toward understanding sexual misconduct by male athletes, much of this research appears to focus on the socio-cultural factors informing the perpetrators' actions. This study takes a different approach, analysing the perspectives of female Australian rules football fans to consider gendered narratives of sexual misconduct. Our findings demonstrate that discourses of individualism, along with a mix of socio-cultural and biological arguments, are used by women to reconcile players' misconduct with continuing support of their sport.

Song and female choice for extrapair copulations in the sedge warbler, Acrocephalus schoenobaenus

Although 90% of passerine birds live in socially monogamous pair bonds, molecular studies have revealed that genetic polygamy occurs in 86% of surveyed passerines, because individuals engage in copulations outside the pair bond (extrapair copulations; EPCs). Most explanations for the occurrence of EPCs involve female gaining indirect benefits from the extrapair male. The sedge warbler is a socially monogamous species in which some offspring result from EPCs (8% in this study). Complex song is a sexually selected male trait used by females which select mates based on a variety of male qualities. We used microsatellite DNA profiling to detect extrapair young and assign paternity. ‘Good genes’ theory predicts that females should engage in EPCs with males of higher quality than their social mate, with resulting fitness benefits. Extrapair males had smaller song repertoires and smaller territories than the social mate. This apparent preference for small-repertoire males as extrapair mates conflicts with the predictions from previous studies of this species. Sudden cessation of song after pairing may mean that song cues are unavailable for later extrapair matings and females may switch to other cues. Such behaviour may lead to different patterns of female choice during social and extrapair mating in the sedge warbler. We conclude that multiple reasons underlie patterns of female choice in this species.

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.

Female labour force participation, fertility and infant mortality in Australia : some empirical evidence from Granger causality tests

This study applies Granger causality tests within a multivariate error correction framework to examine the relationship between female participation rates, infant mortality rates and fertility rates for Australia using annual data from 1960 to 2000. Decomposition of variance and impulse response functions are also considered. The main findings are twofold. First, in the short run there is unidirectional Granger causality running from the fertility rate to female labour force participation and from the infant mortality rate to female labour force participation while there is neutrality between the fertility rate and infant mortality rate. Second, in the long run both the fertility rate and infant mortality rate Granger cause female labour participation.

Determinants of female fertility in Taiwan, 1966–2001 : empirical evidence from cointegration and variance decomposition analysis

This study investigates the determinants of the fertility rate in Taiwan over the period 1966–2001. Consistent with theory, the key explanatory variables in Taiwan's fertility model are real income, infant mortality rate, female education and female labor force participation rate. The test for cointegration is based on the recently developed bounds testing procedure while the long-run and short-run elasticities are based on the autoregressive distributed lag model. Among our key results, female education and female labor force participation rate are found to be the key determinants of fertility in Taiwan in the long run. The variance decom-position analysis indicates that in the long run approximately 45percent of the variation in fertility is explained by the combined impact of female labor force participation, mortality and income, implying that socioeconomic development played an important role in the fertility transition in Taiwan. This result is consistent with the traditional structural hypothesis.

Stress, cortisol and reproduction in female pigs

Two key hypotheses emerge in the literature regarding the impact of stress on reproduction in females of any species. First, prolonged stress impairs reproduction in females. Secondly, acute stress impairs reproduction, if it occurs at a critical time during the precisely timed series of endocrine events that induce oestrus and ovulation. We reviewed studies conducted in female pigs to find support or opposition for these hypotheses in female pigs. We also considered the role of cortisol. We found confirmation that prolonged stress or the prolonged elevation of cortisol can impair reproductive processes in female pigs, but also found that there appear to be some female pigs in which reproduction is resistant to such treatments. Reproduction in female pigs appears to be resistant to acute or repeated acute stress or elevation of cortisol, even if these occur during the series of precisely timed endocrine events that induce oestrus and ovulation. Thus, we propose modified versions of the above hypotheses that are specific to female pigs. Furthermore, while cortisol may mediate the effects of prolonged stress on reproduction in female pigs, there is evidence that, in female pigs, ACTH may require the presence of the adrenal glands to impair reproduction rather than having direct effects.

Intrinsic resistance of female hearts to an ischemic insult is abrogated in primary cardiac hypertrophy

Important sex differences in cardiovascular disease outcomes exist, including conditions of hypertrophic cardiomyopathy and cardiac ischemia. Studies of sex differences in the extent to which load-independent (primary) hypertrophy modulates the response to ischemia-reperfusion (I/R) damage have not been characterized. We have previously described a model of primary genetic cardiac hypertrophy, the hypertrophic heart rat (HHR). In this study the sex differences in HHR cardiac function and responses to I/R [compared to control normal heart rat (NHR)] were investigated ex vivo. The ventricular weight index was markedly increased in HHR female (7.82 ± 0.49 vs. 4.80 ± 0.10 mg/g; P < 0.05) and male (5.76 ± 0.22 vs. 4.62 ± 0.07 mg/g; P < 0.05) hearts. Female hearts of both strains exhibited a reduced basal contractility compared with strain-matched males [maximum first derivative of pressure (dP/dtmax): NHR, 4,036 ± 171 vs. 4,258 ± 152 mmHg/s; and HHR, 3,974 ± 160 vs. 4,540 ± 259 mmHg/s; P < 0.05]. HHR hearts were more susceptible to I/R (I = 25 min, and R = 30 min) injury than NHR hearts (decreased functional recovery, and increased lactate dehydrogenase efflux). Female NHR hearts exhibited a significantly greater recovery (dP/dtmax) post-I/R relative to male NHR (95.0 ± 12.2% vs. 60.5 ± 9.4%), a resistance to postischemic dysfunction not evident in female HHR (29.0 ± 5.6% vs. 25.9 ± 6.3%). Ventricular fibrillation was suppressed, and expression levels of Akt and ERK1/2 were selectively elevated in female NHR hearts. Thus the occurrence of load-independent primary cardiac hypertrophy undermines the intrinsic resistance of female hearts to I/R insult, with the observed abrogation of endogenous cardioprotective signaling pathways consistent with a potential mechanistic role in this loss of protection.

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.
