Putting the Australian Labor Party in international perspective

This paper assesses the Australian Labor Party's current debates over future directions with reference to attempts by the left of centre political parties in other western nations, especially in Western Europe, to deal with the end of the economic "golden age" since the early 1970s and the widespread resurgence of neo-liberal ideologies since the late 1970s. The dominant recent view of such comparisons has been through the ideological lens of the "Third Way". This vision however tends not to see relevant variations between the experiences of social democratic parties in individual Western European nations as they have sought to deal with adverse circumstances since the early 1970s. Nor does the Third Way view sufficiently extend to the widely varying background landscapes: that is, the different levels of historical achievement by left of centre parties in the different nations. Some social democratic parties in European countries are pursuing more progressive political agendas than the British Labour Party under Tony Blair and they are starting from a very different basis of policy achievement and political strength than either the British or Australian labour parties. The nature and extent of these international differences need now to be highlighted from an Australian political perspective in order to better inform the current debate about the range of options for the ALP and the current comparative condition of the Australian party system. As part of this analysis, the relationship between the erosion of the traditional blue-collar support bases of the major left of centre parties in various nations, amid economic restructuring and challenges to traditional immigration patterns, and the rise of support for anti-immigrant policies and parties, need to be carefully examined and evaluated.

Interpretation — appropriation : (making) an example of labor process theory

In this article, the author explores ethically problematic relations that may be reproduced within a genre of interpretive organizational research: namely, (U.K.) labor process theory (LPT). Although the author endorses LPT’s critical and explicitly antioppressive values, he argues that interpretive practices employed by core authors contradict the genre’s value base and function to silence and appropriate challenging empirical elements to affirm LPT’s valued interpretive schema. The author draws out deeply problematic implications of such appropriation through highlighting parallels between interpretation, appropriation, and colonization. The author ends by considering the nature of, and possibility for, more ethical “critical” interpretive organizational research.

Seasonal periodicity of serum vitamin D and parathyroid hormone, bone resorption, and fractures : the Geelong Osteoporosis Study

In this population-based study, seasonal periodicity was seen with reduced serum vitamin D, increased serum PTH, and increased bone resorption in winter. This was associated with an increased proportion of falls resulting in fracture and an increased risk of wrist and hip fractures.

Introduction: In a population of women who reside in a temperate climate and do not generally receive dietary vitamin D supplementation, we investigated whether seasonal vitamin D insufficiency is associated with increased risk of fracture.

Materials and Methods: An observational, cross-sectional, population-based study set in southeastern Australia (latitude 38–39° S). Participants were drawn from a well-defined community of 27,203 women ≥55 years old: 287 randomly selected from electoral rolls, 1635 with incident fractures, and 1358 presenting to a university hospital with falls. The main outcome measures were annual periodicities of ultraviolet radiation, serum 25-hydroxyvitamin D [25(OH)D], serum parathyroid hormone (PTH), serum C-telopeptide (CTx), BMD, falls, and fractures.

Results: Cyclic variations in serum 25(OH)D lagged 1 month behind ultraviolet radiation, peaking in summer and dipping in winter (p < 0.001). Periodicity of serum PTH was the inverse of serum 25(OH)D, with a phase shift delay of 1 month (p = 0.004). Peak serum CTx lagged peak serum PTH by 1–2 months. In late winter, a greater proportion of falls resulted in fracture (p < 0.001). Seasonal periodicity in 439 hip and 307 wrist fractures also followed a simple harmonic model (p = 0.078 and 0.002, respectively), peaking 1.5–3 months after the trough in 25(OH)D.

Conclusions: A fall in 25(OH)D in winter is accompanied by increases in (1) PTH levels, (2) bone resorption, (3) the proportion of falls resulting in fracture, and (4) the frequency of hip and wrist fracture. Whether vitamin D supplementation in winter can reduce the population burden of fractures requires further investigation.

Victorian Labor and the environment : a legacy to be proud of?

From October 1999 through to November 2010, Victoria was governed by Australian Labor Party (ALP) led governments. The ALP‟s defeat at the November 2010 election provides the opportunity to take stock of their policy achievements in the environmental domain, with a particular focus on how the concept of sustainability was considered in the strategic directions pursued and policy and institutional reforms introduced. In assessing their performance, the context within which the ALP governed is considered, an account of the policy trajectory of their three terms in government provided, and the adequacy of this trajectory assessed. While the analysis is focused on Victoria, the lessons drawn may have wider relevance.

Comparing the seasonal survival of resident and migratory oystercatchers : carry-over effects of habitat quality and weather conditions

Events happening in one season can affect life-history traits at (the) subsequent season(s) by carry-over effects. Wintering conditions are known to affect breeding success, but few studies have investigated carry-over effects on survival. The Eurasian oystercatcher Haematopus ostralegus is a coastal wader with sedentary populations at temperate sites and migratory populations in northern breeding grounds of Europe. We pooled continental European ringing-recovery datasets from 1975 to 2000 to estimate winter and summer survival rates of migrant and resident populations and to investigate long-term effects of winter habitat changes. During mild climatic periods, adults of both migratory and resident populations exhibited survival rates 2% lower in summer than in winter. Severe winters reduced survival rates (down to 25% reduction) and were often followed by a decline in survival during the following summer, via short-term carry-over effects. Habitat changes in the Dutch wintering grounds caused a reduction in food stocks, leading to reduced survival rates, particularly in young birds. Therefore, wintering habitat changes resulted in long-term (>10 years) 8.7 and 9.4% decrease in adult annual survival of migrant and resident populations respectively. Studying the impact of carry-over effects is crucial for understanding the life history of migratory birds and the development of conservation measures.

Introgression of domesticated alleles into a wild trout genotype and the impact on seasonal survival in natural lakes

We tested the fitness consequences of introgression of fast-growing domesticated fish into a wild population. Fry from wild and domesticated rainbow trout (Oncorhynchus mykiss) crosses, F1 hybrids, and first- and second-generation backcrosses were released into two natural lakes. Parentage analysis using microsatellite loci facilitated the identification of survivors, so fitness was estimated in nature from the first-feeding stage. Results indicated that under certain conditions, domesticated fish survived at least as well as wild fish within the same environment. Relative growth and survival of the crosses, however, were highly dependent on environment. During the first summer, fastest-growing crosses had the highest survival, but this trend was reversed after one winter and another summer. Although the F1 hybrids showed evidence of outbreeding depression because of the disruption of local adaptation, there was little evidence of outbreeding depression in the backcrosses, and the second-generation backcrosses exhibited a wild-type phenotype. This information is relevant for assessing the multigenerational risk of escaped or released domesticated fish should they successfully interbreed with wild populations and provides information on how to minimize detrimental impacts of a conservation breeding and/or management programme. These data also further understanding of the selection pressures in nature that maintain submaximal rates of growth.
