Risk technology in Australia: The role of the job seeker classification instrument in employment services

Promoted as the key policy response to unemployment, the Job Network constitutes an array of interlocking processes that position unemployed people as `problems' in need of remediation. Unemployment is presented as a primary risk threatening society, and unemployed people are presented as displaying various degrees of riskiness. The Job Seeker Classification Instrument (JSCI) is a `technology' employed by Centrelink to assess `risk' and to determine the type of interaction that unemployed people have with the job Network. In the first instance, we critically examine the development of the JSCI and expose issues that erode its credibility and legitimacy. Second, employing the analytical tools of discourse analysis, we show how the JSCI both assumes and imposes particular subject identities on unemployed people. The purpose of this latter analysis is to illustrate the consequences of the sorts of technologies and interventions used within the job Network.

The role of the board in firm strategy: Integrating agency and organisational control perspectives

The role of the board of directors in firm strategy has long been the subject of debate. However, research efforts have suffered from several deficiencies: the lack of an overarching theoretical perspective, reliance on proxies for the strategy role rather than a direct measure of it and the lack of quantitative data linking this role to firm financial performance. We propose a new theoretical perspective to explain the board's role in strategy, integrating organisational control and agency theories. We categorise a board's approach to strategy according to two constructs: strategic control and financial control. The extent to which either construct is favoured depends on contextual factors such as board power, environmental uncertainty and information asymmetry.

The role of the cyclic peptide backbone in the anti-HIV activity of the cyclotide kalata B1

The plant cyclotides, the largest known family of circular proteins, have tightly folded structures and a range of biological activities that lend themselves to potential pharmaceutical and agricultural applications. Based on sequence homology, they are classified into the bracelet and Mobius subfamilies. The bracelet subfamily has previously been shown to display anti-HIV activity. We show here that a member of the Mobius subfamily, kalata B1, also exhibits anti-HIV activity despite extensive sequence differences between the subfamilies. In addition, acyclic permutants of kalata B1 displayed no anti-HIV activity, suggesting that this activity is critically dependent on an intact circular backbone.

The role of the complement system in ischemia-reperfusion injury

Ischemia-reperfusion (I/R) injury is a common clinical event with the potential to seriously affect, and sometimes kill, the patient. Interruption of blood supply causes ischemia, which rapidly damages metabolically active tissues. Paradoxically, restoration of blood flow to the ischemic tissues initiates a cascade of pathology that leads to additional cell or tissue injury. I/R is a potent inducer of complement activation that results in the production of a number of inflammatory mediators. The use of specific inhibitors to block complement activation has been shown to prevent local tissue injury after I/R. Clinical and experimental studies in gut, kidney, limb, and liver have shown that I/R results in local activation of the complement system and leads to the production of the complement factors C3a, C5a, and the membrane attack complex. The novel inhibitors of complement products may find wide clinical application because there are no effective drug therapies currently available to treat I/R injuries.

Characterization of the role of the Rab GTPase-activating protein AS160 in insulin-regulated GLUT4 trafficking

Insulin stimulates the translocation of the glucose transporter GLUT4 from intracellular vesicles to the plasma membrane. In the present study we have conducted a comprehensive proteomic analysis of affinity-purified GLUT4 vesicles from 3T3-L1 adipocytes to discover potential regulators of GLUT4 trafficking. In addition to previously identified components of GLUT4 storage vesicles including the insulin-regulated aminopeptidase insulin-regulated aminopeptidase and the vesicle soluble N-ethylmaleimide factor attachment protein (v-SNARE) VAMP2, we have identified three new Rab proteins, Rab10, Rab11, and Rab14, on GLUT4 vesicles. We have also found that the putative Rab GTPase-activating protein AS160 (Akt substrate of 160 kDa) is associated with GLUT4 vesicles in the basal state and dissociates in response to insulin. This association is likely to be mediated by the cytosolic tail of insulin-regulated aminopeptidase, which interacted both in vitro and in vivo with AS160. Consistent with an inhibitory role of AS160 in the basal state, reduced expression of AS160 in adipocytes using short hairpin RNA increased plasma membrane levels of GLUT4 in an insulin-independent manner. These findings support an important role for AS160 in the insulin regulated trafficking of GLUT4.

Medial prefrontal cortex control of the Paraventricular hypothalamic nucleus response to psychological stress: Possible role of the bed nucleus of the stria terminalis

The medial prefrontal cortex (mPFC) has been strongly implicated in control of the paraventricular nucleus of the hypothalamus (PVN) response to stress. Because of the paucity of direct projections from the mPFC to the PVN, we sought to investigate possible brain regions that might act as a relay between the two during psychological stress. Bilateral ibotenic acid lesions of the rat mPFC enhanced the number of Fos-immunoreactive cells seen in the PVN after exposure to the psychological stressor, air puff. Altered neuronal recruitment was seen in only one of the candidate relay populations examined, the ventral bed nucleus of the stria terminalis (vBNST). Furthermore, bilateral ibotenic acid lesions of the BNST caused a significant attenuation of the PVN response to air puff. To better characterize the structural relationships between the mPFC and PVN, retrograde tracing studies were conducted examining Fos expression in cells retrogradely labeled with cholera toxin b subunit (CTb) from the PVN and the BNST. Results obtained were consistent with an important role for both the mPFC and BNST in the mpPVN CRF cell response to air puff. We suggest a set of connections whereby a direct PVN projection from the ipsilateral vBNST is involved in the mpPVN response to air puff and this may, in turn, be modulated by an indirect projection from the mPFC to the BNST.
