Women in ICT : guidelines for evaluating intervention programmes

Many intervention programmes to increase the number of women in theInformation and Communications Technology (ICT) profession have been implemented over the last twenty years. Detailed evaluations help us to determine the effectiveness of these programmes yet few comprehensive evaluations appear in the literature.The research reported here describes an investigation of the evaluation of the intervention programmes focusing on increasing the enrolment and retention of females in ICT in Australia. This paper describes an empirical study which explores how evaluation has been and might be conducted and concludes with guidelines for evaluation for those developing programmes for increasing the participation of women in ICT.The guidelines encourage evaluation to be considered early, highlight the importance of establishing objective outcomes and promote the publication of results to build knowledge for those planning programmes in the future. Further, the developed guidelines could adapted and used with other ICT intervention programs.

Complicating hetero-femininities : young women, sexualities and girl power at school

This paper is concerned with expanding knowledge of how femininity/sexuality intersections are constituted in secondary schools. Existing studies have drawn upon Judith Butler’s notion of a ‘heterosexual matrix’ in order to understand how intersections of femininity/sexuality are produced in schools through normative discourses of heterosexuality and gender. Drawing on ‘after-queer’ theoretical resources from within cultural studies that focus on the deployment of notions of sexuality within constructions of intelligible citizenship, I explore how the femininity/sexuality intersection within secondary schools might be complicated, when the significance of discourses of ‘girl power’, linked with successful neoliberal citizenship, is considered. I analyse young women’s discussions of key ‘girl power’ icons in popular culture, generated through fieldwork in an elite girls’ school in Australia. Throughout the analysis I explore how understanding intersections of femininity/sexuality in secondary schools requires an analytical framework that can attend to both familiar notions of heterosexuality and gender – and their ongoing currency – as well as how notions of sexuality are mobilized in the production of successful neoliberal girl citizens. I propose that this analytical approach is useful in terms of avoiding the reinscription of sexuality identity categories in education research.

Raunch culture goes to school? : young women, normative femininities and elite education

Public concern about popular culture’s sexualisation of women and girls is regularly voiced in the Australian media. Young women grow up against a backdrop of ‘raunch culture’ (Levy, 2005), which for some scholars represents a ‘new’ femininity (Gill, 2007), in which ‘hyper-sexual’ forms of (hetero)sexual expression are now expected of young women and girls, despite ostensibly being about choice and personal empowerment. In this article, I explore the constructions of girlhood and femininity amongst young women attending an elite, single-sex, private school in Melbourne, Australia. Elite schooling for girls is often associated with highly classed notions of (hetero)sexual modesty and propriety, epitomised in the reality television program Ladette to Lady. Here I consider how hyper-sexualities are configured within students’ constructions of themselves and others, and I explore their relationship to classed expectations of identity for privileged girls. I examine the role that classed norms of identity play in mediating these girls’ negotiations of hyper-sexualities.

Women doing OK but men lagging behind

Women have all but met the federal government's higher education attainment goals, but the overall population can't reach the target unless men's participation rates improve drastically, according to a Sydney higher education researcher.

Ways in which 'community' benefits frail older women's well-being : '... we are much happier when we feel we belong'

Aim: This paper aims to explore frail older women’s lived experiences of ‘community’ and which aspects of ‘community’ they perceive as beneficial to their well-being.

Method: This qualitative project used a mixed methodological approach which integrated aspects of descriptive phenomenology and grounded theory. Ten frail, older women residing in South East Melbourne, Australia participated in in-depth interviews.

Results: This research obtained a rich and detailed account of the aspects of ‘community’ identified by participants as enhancing their well-being. These included: social contact, community dynamics, feelings of support and positive orientation.

Conclusion: This paper has increased our understanding of the factors supporting well-being of frail older women. Service providers should actively consider how they can strengthen these factors to improve social connectedness for frail older women by the use of volunteers, developing social networks and increasing availability and quality of community-based activities.

The role of micro-organisms (staphylococcus aureus and Candida Albicans) in the pathogenesis of breast pain and infection in lactation women : study protocol

Background: The CASTLE (Candida and Staphylococcus Transmission: Longitudinal Evaluation) study will investigate the micro-organisms involved in the development of mastitis and “breast thrush” among breastfeeding women. To date, the organism(s) associated with the development of breast thrush have not been identified. The CASTLE study will also investigate the impact of physical health problems and breastfeeding problems on maternal psychological health in the early postpartum period.

Methods/Design: The CASTLE study is a longitudinal descriptive study designed to investigate the role of Staphylococcus spp (species) and Candida spp in breast pain and infection among lactating women, and to describe the transmission dynamics of S. aureus and Candida spp between mother and infant. The relationship between breastfeeding and postpartum health problems as well as maternal psychological well-being is also being investigated. A prospective cohort of four hundred nulliparous women who are at least thirty six weeks gestation pregnant are being recruited from two hospitals in Melbourne, Australia (November 2009 to June 2011). At recruitment, nasal, nipple (both breasts) and vaginal swabs are taken and participants complete a questionnaire asking about previous known staphylococcal and candidal infections. Following the birth, participants are followed-up six times: in hospital and then at home weekly until four weeks postpartum. Participants complete a questionnaire at each time points to collect information about breastfeeding problems and postpartum health problems. Nasal and nipple swabs and breast milk samples are collected from the mother. Oral and nasal swabs are collected from the baby. A telephone interview is conducted at eight weeks postpartum to collect information about postpartum health problems and breastfeeding problems, such as mastitis and nipple and breast pain.

Discussion: This study is the first longitudinal study of the role of both staphylococcal and candidal colonisation in breast infections and will help to resolve the current controversy about which is the primary organism in the condition known as breast thrush. This study will also document transmission dynamics of S. aureus and Candida spp between mother and infant. In addition, CASTLE will investigate the impact of common maternal physical health symptoms and the effect of breastfeeding problems on maternal psychological well-being.

Endogenous parathyroid hormone is associated with reduced cartilage volume in vivo in a population-based sample of adult women

Objectives Animal and in vitro studies suggest that parathyroid hormone (PTH) may affect articular cartilage. However, little is known of the relationship between PTH and human joints in vivo.

Design Longitudinal.

Setting Barwon Statistical Division, Victoria, Australia.

Participants 101 asymptomatic women aged 35–49 years (2007–2009) and without clinical knee osteoarthritis, selected from the population-based Geelong Osteoporosis Study.

Risk factors Blood samples obtained 10 years before (1994–1997) and stored at −80°C for random batch analyses. Serum intact PTH was quantified by chemiluminescent enzyme assay. Serum 25-hydroxyvitamin D (25(OH)D) was assayed using equilibrium radioimmunoassay. Models were adjusted for age, bone area and body mass index; further adjustment was made for 25(OH)D and calcium supplementation.

Outcome Knee cartilage volume, measured by MRI.

Results A higher lnPTH was associated with reduced medial—but not lateral—cartilage volume (regression coefficient±SD, p value: −72.2±33.6 mm3, p=0.03) after adjustment for age, body mass index and bone area. Further sinusoidal adjustment (−80.8±34.4 mm3, p=0.02) and 25(OH)D with seasonal adjustment (−72.7±35.1 mm3, p=0.04), calcium supplementation and prevalent osteophytes did not affect the results.

Conclusions A higher lnPTH might be detrimental to knee cartilage in vivo. Animal studies suggest that higher PTH concentrations reduce the healing ability of cartilage following minor injury. This may be apparent in the presence of increased loading, which occurs in the medial compartment, placing the medial cartilage at higher risk for injury.

Does an increase in body mass index over 10 years affect knee structure in a population-based cohort study of adult women?

Introduction : Although obesity is a modifiable risk factor for knee osteoarthritis (OA), the effect of weight gain on knee structure in young and healthy adults has not been examined. The aim of this study was to examine the relationship between body mass index (BMI), and change in BMI over the preceding 10-year period, and knee structure (cartilage defects, cartilage volume and bone marrow lesions (BMLs)) in a population-based sample of young to middle-aged females.

Methods : One hundred and forty-two healthy, asymptomatic females (range 30 to 49 years) in the Barwon region of Australia, underwent magnetic resonance imaging (MRI) during 2006 to 2008. BMI measured 10 years prior (1994 to 1997), current BMI and change in BMI (accounting for baseline BMI) over this period, was assessed for an association with cartilage defects and volume, and BMLs.

Results : After adjusting for age and tibial plateau area, the risk of BMLs was associated with every increase in one-unit of baseline BMI (OR 1.14 (95% CI 1.03 to 1.26) P = 0.009), current BMI (OR 1.13 (95% CI 1.04 to 1.23) P = 0.005), and per one unit increase in BMI (OR 1.14 (95% CI 1.03 to 1.26) P = 0.01). There was a trend for a one-unit increase in current BMI to be associated with increased risk of cartilage defects (OR 1.06 (95% CI 1.00 to 1.13) P = 0.05), and a suggestion that a one-unit increase in BMI over 10 years may be associated with reduced cartilage volume (-17.8 ml (95% CI -39.4 to 3.9] P = 0.10). Results remained similar after excluding those with osteophytes.

Conclusions : This study provides longitudinal evidence for the importance of avoiding weight gain in women during early to middle adulthood as this is associated with increased risk of BMLs, and trend toward increased tibiofemoral cartilage defects. These changes have been shown to precede increased cartilage loss. Longitudinal studies will show whether avoiding weight gain in early adulthood may play an important role in diminishing the risk of knee OA.

Lifestyle factors fail to explain the variation in plasma leptin concentrations in women

To assess the relationship between circulating leptin concentrations, metabolic parameters, and lifestyle factors such as alcohol intake, physical activity level, smoking habits, and reproductive history, a cohort of 359 women was drawn from a population-based study conducted in Victoria, Australia. The parameters measured included body mass index (BMI); waist and hip circumference; blood pressure; and fasting glucose, insulin, triacylglycerol, cholesterol, and leptin concentrations. In addition, a self-administered questionnaire was used to assess reproductive history, physical activity level, alcohol intake, and smoking habits. Our results demonstrated that BMI, body weight, waist circumference, and hip circumference were all strongly correlated with circulating leptin concentrations in this population (r > 0.56, P < 0.001 in all cases). Waist/hip ratio, triacylglycerols, insulin, glucose, and cholesterol were also associated with leptin (P < 0.05), but there was no association between leptin and age, height, or blood pressure. When these associations were adjusted for BMI, age, glucose, and waist circumference were significantly associated with leptin. The lifestyle factors examined did not help to explain the observed variation in leptin concentrations between individuals when results were adjusted for degree of adiposity and age.

Prevalence of osteoporosis in Australian men and women : Geelong osteoporosis study

To the Editor: Few reports have been published on bone mineral density (BMD) among randomly sampled populations. Organisations such as Osteoporosis Australia and the Australian and New Zealand Bone and Mineral Society rely on research to supply reliable data that are representative of the Australian community. This information informs practitioners, researchers and policymakers of the size of the problem of osteoporosis in Australia. Our study aimed to document the proportion of individuals who have reduced BMD.

Prevalence of osteoporosis in Australian women : Geelong Osteoporosis Study

To evaluate the prevalence of osteoporosis at various sites among Australian women, cross-sectional bone mineral density (BMD) data for adult females was obtained from an age-stratified population-based sample (n = 1494; 20–94 yr) drawn at random from the Barwon Statistical Division, a population characteristic of Australia. Age- and weight- (and for three sites, height) matched reference ranges for BMD at the lumbar spine, proximal femur, forearm, and total body were developed using regression techniques. The cutoff BMD level for osteoporosis at the PA spine was 0.917 g/cm² and 0.713 g/cm² at the femoral neck according to the World Health Organization (WHO) guidelines. The upper cutoff level for osteopenia was 1.128 g/cm² at the PA spine and 0.913 g/cm² for the femoral neck. The proportion of Australian women categorized as having osteoporosis at the PA spine, femoral neck, or midforearm ranged from 0.9% among those aged 40–44 yr to 87.0% for those older than 79 yr. This study provides reference data representative of the Australian female population. A large proportion of elderly Australian women has osteoporosis according to the WHO guidelines.

Reference ranges for bone densitometers adopted Australia-wide : Geelong Osteoporosis Study

Bone densitometry reports a measure of fracture risk in comparison with young adults (T-scores) and age-matched peers (Z-scores). To date, each manufacturer has provided its own reference range resulting in lack of uniformity. The Australia and New Zealand Bone and Mineral Society and Osteoporosis Australia have recognized the need to standardize the reference range and have recommended that data generated by the Geelong Osteoporosis Study (GOS) be used Australia-wide. The GOS recruited a random, population-based sample of adult women and measured bone mineral density (BMD) at the proximal femur and spine using a Lunar DPX-L. These data were used to establish reference ranges for Lunar machines and, using conversion equations, for Norland and Hologic machines. The new standardized Australian reference ranges for BMD will enable consistent diagnosis of osteoporosis and categorization of fracture risk across different types of densitometers.

Prevention and treatment of infant and childhood vitamin D deficiency in Australia and New Zealand : a consensus statement

• Vitamin D deficiency has re-emerged as a significant paediatric health issue, with complications including hypocalcaemic seizures, rickets, limb pain and fracture.

• A major risk factor for infants is maternal vitamin D deficiency. For older infants and children, risk factors include dark skin colour, cultural practices, prolonged breastfeeding, restricted sun exposure and certain medical conditions.

• To prevent vitamin D deficiency in infants, pregnant women, especially those who are dark-skinned or veiled, should be screened and treated for vitamin D deficiency, and breastfed infants of dark-skinned or veiled women should be supplemented with vitamin D for the first 12 months of life.

• Regular sunlight exposure can prevent vitamin D deficiency, but the safe exposure time for children is unknown.

• To prevent vitamin D deficiency, at-risk children should receive 400 IU vitamin D daily; if compliance is poor, an annual dose of 150 000 IU may be considered.

• Treatment of vitamin D deficiency involves giving ergocalciferol or cholecalciferol for 3 months (1000 IU/day if < 1 month of age; 3000 IU/ day if 1-12 months of age; 5000 IU/day if > 12 months of age).

• High-dose bolus therapy (300 000-500 000 IU) should be considered for children over 12 months of age if compliance or absorption issues are suspected.
