The ICT disciplines in Australian universities have a strong tradition of industry engagement in curriculum design and implementation particularly through work integrated learning programs. Work integrated learning (WIL) includes industry placements, internships, industry projects and other methods and approaches that aim to enhance the professional practice capabilities of students. There are various stakeholders involved in WIL programs including universities, students, government and industry, each with their own motivations and expectations. Whilst all stakeholders agree on the benefits to students, there are conflicting interests that jeopardise further development and innovation in WIL. This paper reports on surveys of industry and university stakeholders in order to understand representative views and current practices. The findings confirm a lack of a shared understanding between stakeholders regarding roles, responsibilities, models and benefits. The paper concludes with several recommendations regarding the adoption of an outcomes-based approach to the design and implementation of work integrated learning programs that will encourage innovation and quality in WIL.

This report on Student Preferences for Bachelor Degrees at TAFE (Technical and Further Education) institutions is derived from research commissioned by Australia’s National Centre for Student Equity in Higher Education (NCSEHE) hosted at Curtin University and conducted by researchers at Deakin University’s Strategic Centre for Research in Educational Futures and Innovation (CREFI). The report focuses on the influence of schools on their students’ higher education (HE) preferences – particularly their preferences for TAFE bachelor degrees – as recorded by the Victorian and South Australian Tertiary Admissions Centres (VTAC and SATAC). Influence is researched in terms of a school’s socioeconomic status, geographical location and sector. The SATAC data set is considerably smaller, at around 8 per cent of the VTAC data set.Bachelor degrees offered by TAFEs are relatively small in number but a growing higher education option for students in Australia (Gale et al. 2013). The Australian Government’s proposal to extend Commonwealth Supported Places (CSPs) to include Australian higher education not delivered by the nation’s public universities (Department of Education 2014b), is likely to fuel further growth in TAFE bachelor degree offerings. The recent Report of the Review of the Demand Driven Funding System in Australian higher education (Kemp & Norton 2014), which recommended this change, also makes special mention of non-university degree options as something that would be of particular benefit to students from low socioeconomic status backgrounds.The research reported herein is informed by a review of the international research literature, which indicates three main influences on students’ HE preferences: (1) students’ families and communities; (2) the socio-spatial location of their schools; and (3) school practices. This report contributes to understandings on the second of these: the influence of school context (their socio-spatial location) on students’ preferences for TAFE bachelor degrees.The research found that the annual rate of student preferences for TAFE bachelor degrees was relatively stable (at around 1,500 per annum) from 2009 to 2012 but rose significantly (by 30%) in 2013. Students from high socioeconomic status schools (and with an average ATAR of 56.9) were the group that registered the largest number of preferences. The number of preferences for TAFE bachelor degrees lodged by students from metropolitan schools exceeded the preferences of students from schools located in all other regions combined. This might reflect the fact that TAFE institutions offering bachelor degrees tend to be located in metropolitan areas.The research also found that students’ preferences for TAFE bachelor degrees increased after announcement of their Australian Tertiary Admission Rank (ATAR), by between 25 and 30 per cent each year. The post-ATAR increase was most noticeable in the Health and Education fields of study and among students from high socioeconomic status schools. The report concludes that while the public perception of TAFE is that it is a sector primarily for students from low SES backgrounds, this is not reflected in students’ preferences for TAFE bachelor degrees. Instead, the preferences of students from high socioeconomic schools outnumber other SES groups in almost every TAFE-degree field of study. This includes the fields of Health and Education, which are often seen to be typical low SES student choices in universities (Gale & Parker 2013).

High amylose cross-linked to different degrees with sodium trimetaphosphate by varying base strength (2% or 4%) and contact time (0.5-4 h) was evaluated as non-compacted systems for sodium diclophenac controlled release. The physical properties and the performance of these products for sodium diclophenac controlled release from non-compacted systems were related to the structures generated at each cross-linking degree. For samples at 2% until 2 h the swelling ability, G' and eta* values increased with the cross-linking degree, because the longer polymer chains became progressively more entangled and linked. This increases water uptake and holding, favoring the swelling and resulting in systems with higher viscosities. Additionally, the increase of cross-linking degree should contribute for a more elastic structure. The shorter chains with more inter-linkages formed at higher cross-linking degrees (2%4h and 4%) make water caption and holding difficult, decreasing the swelling, viscosity and elasticity. For 2% samples, the longer drug release time exhibited for 2%4h sample indicates that the increase of swelling and viscosity contribute for a more sustained drug release, but the mesh size of the polymeric network seems to be determinant for the attachment of drug molecules. For the 4% samples, smaller meshes size should determine less sustained release of drug. (C) 2008 Elsevier B.V. All rights reserved.

Objectives: We have analyzed the peripheral insulin and glucose sensitivity in vivo, and islet function ex vivo in rats with different degrees of insulin resistance induced by dexamethasone (DEX).Methods: Dexamethasone, in the concentrations of 0.1 (DEX 0.1), 0.5 (DEX 0.5), and 1.0 mg/kg body weight (DEX 1.0) was administered daily, intraperitoneally, to adult Wistar rats for 5 days, whereas controls received saline.Results: Dexamethasone treatment induced peripheral insulin resistance in a dose-dependent manner. At the end of the treatment, only DEX 1.0 rats showed significant increase of postabsorptive blood glucose and serum triglycerides, and nonesterified fatty acids levels. Incubation of pancreatic islets in increasing glucose concentrations (2.8-22 mM) led to an augmented insulin secretion in all DEX-treated rats. Leucine, carbachol, and high KCl concentrations induced the insulin release in DEX 0.5 and DEX 1.0, whereas arginine augmented secretion in all DEX-treated groups.Conclusions: We demonstrate that in DEX 0.5 and, especially in DEX 0.1 groups, but not in DEX 1.0, the adaptations that occurred in the endocrine pancreas are able to counteract metabolic disorders (glucose intolerance and dyslipidemia). These animal models seem to be interesting approaches for the study of degrees of subjacent effects that may mediate type 2 diabetes (DEX 1.0) and islet function alterations, without collateral effects (DEX 0.1 and DEX 0.5).

The reproductive biology of Arenaeus cribrarius from Ubatuba, São Paulo State, Brazil, was studied. Swimming crabs were sampled monthly for two years with otter trawls in two bays. A total of 941 males and 1,012 females were examined. Mating took place mainly in autumn involving postmolt females and intermolt males. At that time, gonad regression was verified in adult males, due to spermatophore transfer, and the molting of adult females. Ovigerous females or females with mature gonads were present year-round but more frequently captured during spring and summer. We found that 19, of all adult females were premolt, which indicated the occurrence of another mature instar and thus the absence of a well-defined terminal molt after puberty. Intermolt males were captured throughout the whole study period.

A total number of 4824 Mustelus schmitti was sampled. Females ranged from 25 to 93 em in spring and from 28 to 90 cm in summer. Males ranged from 34 to 82 and from 28 to 77 cm, respectively. Length composition of the population showed significant differences between spring and summer being females larger than males. Total length distribution did not show significant differences between cruises. Males density varied significantly between cruises while for the females no significant variation was observed. In the spring cruise, both sexes occurred at depths lower than 50 in. Females occurred in the whole area with adult occurrence only above 35 degrees 30'S. Mature males occurred throughout the area, immature males occurring in two trawls in Samborombon Bay. The summer cruise showed a discontinuous distribution of the species along the study area resulting in spatial segregation in two groups with immature females predominating in both of them.

P>The softnose skates Bathyraja brachyurops and Bathyraja macloviana represent an important portion of the skate catches of the Uruguayan trawling fleet in the southwestern Atlantic. From March to October 2004, specimens of these species were collected at 75-200 m depth range in the area situated between latitudes 37 degrees 00'-39 degrees 30'S. For B. brachyurops, total length at which 50% of the specimens were retained by the gear was 68.0 cm for both sexes; T(L50) was estimated at 65.4 cm for males and 67.0 cm for females. For B. macloviana, total length at which 50% of the specimens were retained was 56.0-57.0 cm for both sexes; T(L50) was estimated at 53.5 cm for males and 52.0 cm for females. Egg capsule length varied from 79-91 mm in B. brachyurops and 69-75.5 mm in B. macloviana. In both species, capsules displayed striated surfaces and similar gross morphology, although egg capsules of B. macloviana had more robust anterior horns and a smaller size than those of B. brachyurops. Egg capsules of the latter also exhibited microscopical prickles. Capsule edges were laterally keeled with a groove along the keel, and a straight and transverse velum was present in the egg capsules of both species.

Oxygen consumption rate was measured continuously in young tegu lizards Tupinambis merianae exposed to 4 d at 25 degrees C followed by 7-10 d at 17 degrees C in constant dark at five different times of the year. Under these conditions, circadian rhythms in the rate of oxygen consumption persisted for anywhere from 1 d to the entire 2 wk in different individuals in all seasons except the winter. We also saw a progressive decline in standard oxygen consumption rate (at highly variable rates in different individuals) to a very low rate that was seasonally independent (ranging from 19.1 +/- 6.2 to 27.7 +/- 0.2 mL kg(-1) h(-1) across seasons). Although this degree of reduction appeared to take longer to invoke when starting from higher metabolic rates, tegu lizards reduced their metabolism to the low rates seen in winter dormancy at all times of the year when given sufficient time in the cold and dark. In the spring and summer, tegus reduced their standard metabolic rate (SMR) by 80%-90% over the experimental run, but only roughly 20%-30% of the total fall was due to the reduction in temperature; 70%-80% of the total fall occurred at constant temperature. By autumn, when the starting SMR on the first night at 25 degrees C was already reduced by 59%-81% (early and late autumn, respectively) from peak summer values, virtually all of the fall (63%-83%) in metabolism was due to the reduction in temperature. This suggests that the temperature-independent reduction of metabolism was already in place by autumn before the tegus had entered winter dormancy.

We set up a new calculational framework for the Yang-Mills vacuum transition amplitude in the Schrodinger representation. After integrating out hard-mode contributions perturbatively and performing a gauge-invariant gradient expansion of the ensuing soft-mode action, a manageable saddle-point expansion for the vacuum overlap can be formulated. In combination with the squeezed approximation to the vacuum wave functional this allows for an essentially analytical treatment of physical amplitudes. Moreover, it leads to the identification of dominant and gauge-invariant classes of gauge field orbits which play the role of gluonic infrared (IR) degrees of freedom. The latter emerge as a diverse set of saddle-point solutions and are represented by unitary matrix fields. We discuss their scale stability, the associated virial theorem and other general properties including topological quantum numbers and action bounds. We then find important saddle-point solutions (most of them solitons) explicitly and examine their physical impact. While some are related to tunneling solutions of the classical Yang-Mills equation, i.e. to instantons and merons, others appear to play unprecedented roles. A remarkable new class of IR degrees of freedom consists of Faddeev-Niemi type link and knot solutions, potentially related to glueballs.
