Should early childhood be a priority period for obesity prevention?

This thesis explored a range of issues relating to overweight and obesity in children aged 0 to 5 years in Victoria, Australia. Key findings included relatively low prevalence and decreasing trends of overweight and obesity, and strong existing support for health behaviours in kindergartens and child care services.

An investigation on asset allocation and performance measurement for unit trust funds in Malaysia using multifactor model : a post crisis period analysis

This study examines the pattern of asset allocation and the performance of unit trust in Malaysia over the post crisis period by using risk-adjusted performance measures and multi-factor model from the year 2000 to 2004. Evidence from the statistics suggests that an active asset allocation strategy had been observed among Malaysian fund managers during the post Asian financial crisis. It is also suggested that investment allocation in equity remained a dominant vehicle for investment and asset allocation. Findings from multifactor model suggest that all funds of different objectives registered positive alphas except for income funds, with growth funds being among the top. While balanced funds registered highest diversification effectively, diversifying away about 70%-80% of unsystematic risk, the momentum factor is not among the important elements to explain unit trust performance in Malaysia.

State–Chaebol relations in the post-crisis period

This article examines contemporary Korean capitalism via an analysis of state-chaebol relations in the post-crisis period. The Korean state played a prominent role in industrial and financial restructuring after the crisis. Some scholars argue that a 'new' state has emerged in Korea, with the activism during the financial crisis representing only a temporary diversion from the shift towards a 'competition state'. Others claim that the Korean state still seeks to directly shape economic outcomes: some policy instruments have changed, but strategic intent, defined here as the will to directly manage investment flows and shape economic structures, has not. The transition of Korean capitalism from the developmental state system towards neo-liberalism, this article argues, is far from complete. Emphasizing the situated choices of state elites and the challenging political context in which they find themselves, we presume a condition of mutual dependence between the state and chaebols. Given incidences of conflict in the post-crisis context, we argue that the state has not fully reasserted its will over the chaebols. The restructuring of chaebols ('Big Deals') are best understood as symbolic measures intended to garner external support for the Korean state rather than unfettered exercise of strategic intent. At the same time, we go beyond existing accounts of 'state decline' by highlighting the place of economic performance by the chaebols as the preeminent criteria for state support. The state and chaebols remain central to Korean capitalism, even in its current hybrid and somewhat dysfunctional form.

Assessing effects of diel period, gear selectivity and predation on patterns of microhabitat use by fish in a mangrove dominated system in SE Australia

The relative value of temperate mangroves to fish, and the processes driving patterns of microhabitat use within this habitat, are unknown. There are 3 quickly identifiable microhabitats within temperate Australian mangroves: (1) forest (the area of mangroves with trees); (2) pneumatophores (the area directly seaward of the forest without trees but with pneumatophores [aerial roots]); and (3) channel (the area directly seaward of the pneumatophores without gross structural attributes such as trees or pneumatophores). Duplicate fyke and gill nets were both initially used to sample fish in the 3 microhabitats described above. Sampling took place across the seaward edge of mangroves on 10 sampling occasions (5 night and 5 day), in a large estuarine system in SE Australia. Fish assemblages (693 fish from 20 species and 15 families) varied significantly (p < 0.05) between the forest and the channel, and between diel periods for each gear (net type), but there was little difference in the assemblage structure of fish between forest–pneumatophore or pneumatophore–channel microhabitats. Juvenile lifestages (61% of all fish) and commercially important taxa (76%) were common. Abundance, biomass and species richness of fish were generally lower in the forest than the other microhabitats, but this pattern varied significantly (p < 0.05) between diel periods, among sampling occasions, and with water depth. Highly quantitative pop nets provided a preliminary assessment of whether differential gear selectivity caused patterns between microhabitats, but less rich fish assemblages were again recorded in forests than in pneumatophores. The importance of predation in structuring fish assemblages across microhabitats was assessed by measuring survival of juvenile fish tethered in 3 predation treatments (predator exclusion, cage control, and uncaged). Survival rates were high across the predator treatments and did not vary among microhabitats. The variation in fish assemblages across microhabitats within mangroves was not consistent with a model of mangrove structure providing a refuge for juvenile fish from predation, but instead could indicate differences in efficiency of gear types among microhabitats and/or other ‘edge effect’-driven processes such as the provision of food and/or shelter.

Changes in behaviour during the inter-nesting period and post-nesting migration for Ascension Island green turtles

Satellite transmitters were attached to green turtles Chelonia mydas while they were nesting on Ascension Island in the South Atlantic (7°57'S, 14°22'W) and individuals were subsequently monitored during the inter-nesting period and the post-nesting migration to Brazil. During the inter-nesting period, data from the transmitters suggested that turtles generally stayed within 5 km of the nesting beach on which they had originally been observed. During both the inter-nesting period and migration, turtles were submerged the vast majority (>95%) of the time, suggesting that they neither basked at the surface nor drifted passively during migration to any great extent. There was a clear dichotomy in submergence behaviour, with submergences tending to be of short duration during post-nesting migration (mean = 7.3 min, 3318 h of data from 5 individuals) and of longer duration during the inter-nesting period (mean = 22.1 min, 714 h of data from 5 different individuals). As submergence duration is generally linked to activity levels in sea turtles, this pattern suggests that turtles were comparatively inactive during the inter-nesting period and comparatively active during migration. During both the inter-nesting period and the post-nesting migration, diel submergence patterns were detected with dive duration tending to be longer at night. As the turtles migrated WSW from Ascension Island, there was a reduction in their speed of travel. A numerical model of the near-surface currents suggested that this reduction was associated with the weakening of the WSW flow of the prevailing South Atlantic Equatorial Current.

Fast and Fashionable: The Girls in the Girl of the Period Miscellany

The Girl of the Period Miscellany is particularly interesting in that it reworked the Girl of the Period from an object of disdain into a figure who might be humorous, but who was also engaging and sympathetic. Rather than being easily categorized and dismissed, the Girl of the Period found in the Miscellany has some characteristics that invite satire but she is also capable, entertaining, and attractive. Moreover, there is a significant difference between thinking about the article that spawned the phenomenon and the Miscellany itself. Appearing in the conservative Saturday Review, the article was provocative and seemingly intended to be so. In contrast, the Miscellany was designed to attract and retain a readership. This article will examine how and why the Miscellany is able to resist Linton’s simplistic construction of the Girl of the Period and instead depicts a variety of different girls who, although their behaviour might be more “modern,” are nonetheless worthy of respect and attention as pure, virtuous, middle-class girls. In addition, the publication of the Miscellany demonstrates the challenges of attracting as readers a group of girls and young women whose self-conception was rapidly shifting at the end of the 1860s.

Duration of unemployment and suicide in Australia over the period 1985–2006: an ecological investigation by sex and age during rising versus declining national unemployment rates

Background The relationship between unemployment and suicide may be sensitive to demographic factors, national unemployment rates, and length of time without employment. This study investigated these factors in relation to suicide in Australia for the period 1985–2006, in an ecological study. Methods The outcome variable was annual suicide rate by age group, sex and the eight states and territories over 22 years of observation (total observations=1760). The main predictor variable was the average duration of unemployment in the population, categorised into three time periods (<2 weeks, 2–4 weeks, >4 weeks). Poisson regression models were used to investigate the relationship between duration of unemployment and suicide over the years 1985–2006 in a series of cross-sectional analyses. Interaction analyses indicated significant differences during periods of declining or increasing labour market opportunity and by age group. Results During periods of declining unemployment rates in the country, longer durations of unemployment were associated with higher male suicide rates. During periods of increasing unemployment in the country, longer unemployment duration was associated with lower male suicide rates. Effect modification was also apparent by age-group, with stronger associations between unemployment duration and male suicide evident in those aged 25–34 and 55–64, and weaker associations in those aged 15–24 and 44–54 years. Longer length of unemployment was not associated with an increase in female suicide rates. Conclusions The labour market opportunities in Australia modified the effect of duration of unemployment on suicide, and the effect was more prominent in men and older age groups. This may reflect social norms and acceptability about unemployment, as well as life-stage influences associated with transitions into and out of the labour market.
