Exploring girl power : gender, literacy and the textual practices of young women attending an elite school

Popular discourses concerning the relationship between gender and academic literacies have suggested that boys are lacking in particular, school-based literacy competencies compared with girls. Such discourses construct “gender” according to a binary framework and they obscure the way in which literacy and textual practices operate as a site in which gendered identities are constituted and negotiated by young people in multiple sites including schooling, which academic inquiry has often emphasized. In this paper I consider the school-based textual practices of young women attending an elite school, in order to explore how these practices construct “femininities”. Feminist education researchers have shown how young women negotiate discourses of feminine passivity and heterosexuality through their reading and writing practices. Yet discourses of girlhood and femininity have undergone important transformations in times of ‘girl power’ in which young women are increasingly constructed as successful, autonomous and sexually agentic. Thus young women’s reading and writing practices may well operate as a space in which new discourses around girlhood and femininity are constituted. Throughout the paper, I utilize the notion of “performativity”, understood through the work of Judith Butler, to show how textual practices variously inscribe and negotiate discourses of gender. Thus the importance of textual work in inscribing and challenging notions of gender is asserted. I argue that critical literacy is just as important, but perhaps no more guaranteed, within elite girls’ education as it is within boys’ education.

Determinants of local abundance in a major radiation of Australian passerines (Aves: Meliphagoidea)

Aim  To identify the factors that contribute to variation in abundance (population density), and to investigate whether habitat breadth and diet breadth predict macroecological patterns in a suborder of passerine birds (Meliphagoidea).
Location  Australia (including Tasmania).
Methods  Mean abundance data were collated from site surveys of bird abundance (the Australian Bird Count); range size and latitudinal position data from published distribution maps; and body mass and diet breadth information from published accounts. A diversity index of habitats used (habitat breadth) was calculated from the bird census data. We used bivariate correlation and multiple regression techniques, employing two phylogenetic comparative methods: phylogenetic generalized least squares and independent contrasts.

Results  Body mass and latitude were the only strong predictors of abundance, with larger-bodied and lower-latitude species existing at lower densities. Together, however, body mass and latitude explained only 11.1% of the variation in mean abundance. Range size and habitat breadth were positively correlated, as were diet breadth and body mass. However, neither range size, nor habitat breadth and diet breadth, explained patterns in abundance either directly or indirectly.
Main conclusions  Levels of abundance (population density) in meliphagoid birds are most closely linked to body mass and latitudinal position, but not range size. As with many other macroecological analyses, we find little evidence for aspects of niche breadth having an effect on patterns of abundance. We hypothesize that evolutionary age may also have a determining effect on why species tend to be rarer (less abundant) in the tropics.

How did we ever arrive at the conclusion that teachers are the problem? A critical reading in the discourses of Australian schooling

A Quality Teacher debate is presented within historical and contemporary contexts, including a political history of Australian schooling over the last 20 or so years. It is argued that there is a crisis of confidence in schooling, which is currently being played out by positioning teachers as the 'problem' and not just the 'solution' to this crisis.

Early life stress and child temperament style as predictors of childhood anxiety and depressive symptoms : findings from the longitudinal study of Australian children

Objective. The purpose of this study was to determine whether the relationship between stressful infant environments and later childhood anxiety and depressive symptoms varies as a function of individual differences in temperament style.

Methods. Data was drawn fromthe Longitudinal Study of Australian Children (LSAC). This study examined 3425 infants assessed at three time points, at 1-year, at 2/3 years and at 4/5 years. Temperament was measured using a 12-item version of Toddler Temperament Scale (TTS) and was scored for reactive, avoidant, and impulsive dimensions. Logistic regression was used to model direct relationships and additive interactions between early life stress, temperament, and emotional symptoms at 4 years of age. Analyses were adjusted for socioeconomic status, parental education, andmarital status.

Results. Stressful family environments experienced in the infant’s first year of life (high versus low) and high reactive, avoidant, and impulsive temperament styles directly and independently predicted anxiety and depressive problems in children at 4 years of age. There was no evidence of interaction between temperament and family stress exposure.

Conclusions. Both infant temperament and stress exposures are independent and notable predictors of later anxiety and depressive problems in childhood. The risk relationship between stress exposure in infancy and childhood emotion problems did not vary as a function of infant temperament. Implications for preventive intervention and future research directions are discussed.

A comparative analysis of Australian sex offender legislation for sex offender registries

Australia has followed the course taken by other English-speaking countries in recent years of enacting legislation that requires convicted sexual offenders to register personal details with law enforcement agencies. These laws have been enacted to protect the public from the perceived threat posed by sex offenders, but have been written with little apparent reference to the available research literature about the nature and extent of this threat. In addition, there is no empirical evidence supporting the effectiveness of legislatively based sex offender registries to either reduce sexual offending or to enable the police to investigate sex crimes and apprehend offenders. This article compares and contrasts the current laws governing sex offender registration enacted by the various states and territories in Australia, and offers a critical analysis of their provisions in light of the research literature on sexual offending.

Volatility decomposition of Australian housing prices

This study examines the volatility pattern of Australian housing prices. The approach for this research was to decompose the conditional volatility of housing prices into a “permanent” component and a “transitory” component via a Component-Generalized Autoregressive Conditional Heteroskedasticity (C-GARCH) model. The results demonstrate that the shock impact on the short-run component (transitory) is much larger than the long-run component (permanent), whereas the persistence of transitory shocks is much less than permanent shocks. Moreover, both permanent and transitory volatility components have different determinants. The results provide important new insights into the volatility pattern of housing prices which has direct implications for investment in housing by owner-occupiers and investors.

Corporate governance and information technology : findings from an exploratory survey of Australian organizations

An exploratory survey (n = 57) of the Melbourne Chapter of the Information Systems Audit and Control Association was conducted to ascertain the attitudes and practices relating to corporate governance and the corporate governance of Information Technology (CGIT) in Australia. The survey found the respondents had clear views on corporate governance but most were not engaged with it, the organizational approach to corporate governance and its expected benefits was largely conformance oriented, awareness of CGIT management frameworks and associated standards was high but implementation was not widespread, and although the CGIT standard ISOIIEC 38500 was not widely implemented IT practitioners agreed with its principles. We conclude that the value of the CGIT standard has yet to be recognised by executives in Australia.

Reconceptualising engagement : a study of Australian academics

The management of human capital is a strategic imperative for knowledge based firms such as universities. Human capital has been described as the investment in people necessary to build the skills and capabilities to operate at their full potential and enable them to act in ways that enhance the competitiveness of organisations. This thesis is set amidst the series of changes made to the Australian Higher Education sector that have had a profound effect on the management of its human capital. The changes have larg ely been driven by government policy in response to globalisation, increased competition and technological advances. As a result the climate of universities has moved to a more cost efficiency-focused managerialism. Various studies have illustrated the significant consequences for the academic workforce and the way in which work has changed in the sector. Academics now face greater accountability for the quality and quantity of their teaching and research at a time when university funding has been constrained. The results have not been all positive for the quality of academics’ working lives and evidence points to heavy workloads and a steadily disengaging workforce. Despite this, many of the sectoral changes rely on an engaged and cooperative workforce to bring about greater productivity and quality of education to attract a larger share of international and domestic students. ... The two aims of this thesis are: to clarify the current definitions of engagement by bringing together the constructs and concepts that contribute to engagement; and to provide insight into the dimensions that shape engagement in Australian business academics ... The thesis also contributes to the dialogue on human capital and in particular, how it can be harnessed in key areas such as the knowledge industries and for targeted purposes such as the management of talent.

An examination of Australian gold mining firms' exposure over the collapse of gold price in the late 1990s

Purpose – The purpose of this study is to examine the exposures of Australian gold mining firms in the highly volatile period from 1995 to 2000. This period has been characterized by significant changes in gold price due to bulk sale of gold by collective central banks. Specifically, the paper aims to investigate several firm-specific factors that are hypothesized to carry substantial influence on gold beta.

Design/methodology/approach – To estimate gold beta, we use the following multifactor model: R_g,_t = a+ß_gGPR_t + ß_xFXR_t + ß_mR_m,_t + _Et , where R_g,_t is the return on the gold stock Index at time t, GPR_t is the gold price return denominated in US dollar at time t, FXR_t is the foreign exchange return of Australian dollar in terms of US dollar at time t, R_m,t is the market return at time t, and _Et is the random error term at time t.

Findings – The paper finds that the values of gold beta are consistently greater than one, implying the sensitive nature of firms’ stock returns to gold price changes. This also suggests that investors holding gold mining stock would receive higher percentage increases in stock returns from a percentage increase in gold price returns, as opposed to investors holding gold bullion. Furthermore, these values have changed substantially over time with significant changes in gold price volatility. The most important and consistent relationship that we find is the impact of firms’ hedging behavior on their respective gold betas. This is consistent with Tufano’s study. It implies that firms, which hedge a greater proportion of their gold reserves, are less sensitive to movements in gold prices. The finding therefore supports the risk management theory that hedging increases shareholder’s wealth. However, cash operating costs, cash reserves and the level of gold production seem to influence very little on the firms’ exposure to gold price changes.

Originality/value – This study is of interest and important to the stock mining companies and investors because the extent of the effect of gold price movements on the stock returns of gold mining companies has significant impacts on returns for both firms and investors especially in their risk management and investment decisions, respectively.

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.
