Another opportunity lost? Victorian Labor's enactment of sustainability, 1999-2010

‘Sustainability’ provides the dominant frame for environmental policy debate, even though there is considerable debate to as to what sustainability is, why is it needed, and how can it be progressed. From 1999 through to 2010, Victoria was governed by Australian Labor Party (ALP) led governments that, at times, actively pursued the goal of sustainable development. This culminated in the stated ambition for Victoria to be ‘world leaders in environmental sustainability debate and practice’. This paper explores the way in which sustainability was enacted by Victorian Labor while in government. The evidence indicates that the potential of Victorian Labor's vision was never realized, and that it failed to significantly reform the neoliberal policy settings it inherited.

Turnover of bone marrow-derived cells in the irradiated mouse cornea

In light of an increasing awareness of the presence of bone marrow (BM)-derived macrophages in the normal cornea and their uncertain role in corneal diseases, it is important that the turnover rate of these resident immune cells be established. The baseline density and distribution of macrophages in the corneal stroma was investigated in Cx3cr1gfp transgenic mice in which all monocyte-derived cells express enhanced green fluorescent protein (eGFP). To quantify turnover, BM-derived cells from transgenic eGFP mice were transplanted into whole-body irradiated wild-type recipients. Additionally, wild-type BM-derived cells were injected into irradiated Cx3cr1+/gfp recipients, creating reverse chimeras. At 2, 4 and 8 weeks post-reconstitution, the number of eGFP+ cells in each corneal whole mount was calculated using epifluorescence microscopy, immunofluorescence staining and confocal microscopy. The total density of myeloid-derived cells in the normal Cx3cr1+/gfp cornea was 366 cells/mm2. In BM chimeras 2 weeks post-reconstitution, 24% of the myeloid-derived cells had been replenished and were predominantly located in the anterior stroma. By 8 weeks post-reconstitution 75% of the myeloid-derived cells had been replaced and these cells were distributed uniformly throughout the stroma. All donor eGFP+ cells expressed low to moderate levels of CD45 and CD11b, with approximately 25% coexpressing major histocompatibility complex class II, a phenotype characteristic of previous descriptions of corneal stromal macrophages. In conclusion, 75% of the myeloid-derived cells in the mouse corneal stroma are replenished after 8 weeks. These data provide a strong basis for functional investigations of the role of resident stromal macrophages versus non-haematopoietic cells using BM chimeric mice in models of corneal inflammation.

Does globalization weaken labor unions in developing countries?

For a developing economy with a given urban wage rate, globalization in capital markets strengthens labor unions. This result hinges on the fixed urban wage rate, which leads to a constant capital–labor ratio in the urban sector. Globalization via capital inflows not only enhances the employment effect of unionization but also reduces the rent-shifting related loss in production inefficiency to domestic capital, lending a support to labor unions for developing economies. This result is contrary to the common belief that labor unions tend to be weakened during the globalization process observed after 1980s in many developed economies.

The mediating effect of internal service quality on employee turnover – empirical evidence from Taiwanese nurses

Informed by social exchange theory (SET) this study examines the role of trust in strategic alliances. Interviews were conducted with 17 participants who were strategic alliance managers in their organization. The study finds that trust is important to strategic alliance managers, and without it alliance managers would find it difficult to keep their alliance going. Trust is built over time, and based on the past experiences that the alliance manager has with their partner. The study found that prior networks, timely and appropriate communication and information exchange, fairness preservation and inter-firm adaptation were important in developing trust in the strategic alliance.

Get fact: were there really 50,000 boat arrivals a year under Labor?

Tony Abbott has claimed that before he “stopped the boats”, they were coming in at a rate of 50,000 a year. Is that true? David Tittensor, a research fellow to the UNESCO Chair, with Deakin’s Centre for Citizenship and Globalisation, checks the claim.

The effects of leader-member exchange and employee wellbeing towards employee turnover intention

 Research studies the role of employee wellbeing in relationship of LMX and turnover intention. Academicians from the community colleges, Malaysia were the respondents and structural equation modelling (SEM) was used. Results indicated that LMX is significantly predicts turnover intention and revealed the relationship between LMX and turnover intention decreases when factor on employee wellbeing is amended.

Migrants as Homo economicus : explaining the emerging phenomenon of a shortage of migrant labor in China's coastal provinces

The problem of a shortage of migrant labor is a new development in China's coastal provinces. We discuss the reasons for this emerging phenomenon using a conceptual framework that extends the traditional Lewis dualistic labor market model to incorporate a migrant labor market. We emphasize that migrant labor shortage in China not only reflects a declining wage gap between what peasants receive and what migrants can earn in the cities, but also the institutional legacies of the planning era such as the hukou (household registration) system which discriminates against migrants vis-a-vis urban residents in terms of access to social insurance and other social services. We proceed to draw on a unique survey of migrants and urban residents collected in Jiangsu to show that migrants receive lower incomes, and they have poorer access to social insurance than those with an urban registration in China's cities. Our findings have important implications for the alleviation of the migrant labor shortage problem.

Measurement of a MMP-2 degraded Titin fragment in serum reflects changes in muscle turnover induced by atrophy.

In this study we sought to determine whether a Titin peptide fragment can serve as a clinical biomarker for changes in muscle mass.

The association between critical illness and changes in bone turnover in adults: a systematic review

Critical illness may lead to altered bone turnover and associated adverse health outcomes. This systematic review found moderate evidence for a positive association between critical illness and increased bone turnover. Prospective cohort studies that identify the extent and risk factors for critical illness related bone loss are required.

ATGL-mediated triglyceride turnover and the regulation of mitochondrial capacity in skeletal muscle

Emerging evidence indicates that skeletal muscle lipid droplets are an important control point for intracellular lipid homeostasis and that regulating fatty acid fluxes from lipid droplets might influence mitochondrial capacity. We used pharmacological blockers of the major triglyceride lipases, adipose triglyceride lipase (ATGL) and hormone-sensitive lipase, to show that a large proportion of the fatty acids that are transported into myotubes are trafficked through the intramyocellular triglyceride pool. We next tested whether increasing lipolysis from intramyocellular lipid droplets could activate transcriptional responses to enhance mitochondrial and fatty acid oxidative capacity. ATGL was overexpressed by adenoviral and adenoassociated viral infection in C2C12 myotubes and the tibialis anterior muscle of C57Bl/6 mice, respectively. ATGL overexpression in C2C12 myotubes increased lipolysis, which was associated with increased peroxisome proliferator-activated receptor (PPAR)-∂ activity, transcriptional upregulation of some PPAR∂ target genes, and enhanced mitochondrial capacity. The transcriptional responses were specific to ATGL actions and not a generalized increase in fatty acid flux in the myotubes. Marked ATGL overexpression (20-fold) induced modest molecular changes in the skeletal muscle of mice, but these effects were not sufficient to alter fatty acid oxidation. Together, these data demonstrate the importance of lipid droplets for myocellular fatty acid trafficking and the capacity to modulate mitochondrial capacity by enhancing lipid droplet lipolysis in vitro; however, this adaptive program is of minor importance when superimposing the normal metabolic stresses encountered in free-moving animals.
