New learning networks and their invisible students : policy as simulation or the avoidance game?

Within a climate of policy hysteria, it is often claimed that a 'preoccupation with performance' develops, focussing on individual success stories, resulting in 'fad-like waves of adoption and abandonment'. Within this increasing pace and intensity of reform, new networks are formed and new relationships developed, with key players taking on new forms of identity to morph into the constantly changing policy climate. Despite continued evidence of young people's pathways from school being more like mosaic than linear, new policy still seeks to define and limit the possible lines of flight and trajectories, closely managing the education and training of young people at risk. In Victoria, the major policy initiative has involved the establishment of LLENs, the local all purpose solution to young people who might not be sticking to the linear policy pathway. So are we involved in 'an avoidance game', filling up the post compulsory policy space with more and more policies, which in fact seek to continue to regulate and constrain young people, rather than supporting them? This paper interrogates the policies and practices which have created the learning networks, of the SGR LLEN through policy analysis and case studies.

Individual foraging strategies in Australasian gannets (Morus serrator)

The individual foraging behaviour of Australasian gannets (Morus serrator) was studied using GPS and time-depth recorders. Gannets were found to forage at average maximum distances of 49 km (± 39 km) from the colony, with total foraging path lengths of 143 km (± 108 km) and foraging trip durations of 13.9 h (± 11 h). During foraging trips gannets spent on average 48.7% (± 17.6) of the time flying and made 37 (± 30.4) dives per trip, with an average maximum depth of 3.6 m (± 1 m). However, considerable variation in individual foraging strategies were recorded and these will be discussed in relation to individuals age, breeding experience and sex.

Individual stable space : an approach to face recognition under uncontrolled conditions

There usually exist many kinds of variations in face images taken under uncontrolled conditions, such as changes of pose, illumination, expression, etc. Most previous works on face recognition (FR) focus on particular variations and usually assume the absence of others. Instead of such a ldquodivide and conquerrdquo strategy, this paper attempts to directly address face recognition under uncontrolled conditions. The key is the individual stable space (ISS), which only expresses personal characteristics. A neural network named ISNN is proposed to map a raw face image into the ISS. After that, three ISS-based algorithms are designed for FR under uncontrolled conditions. There are no restrictions for the images fed into these algorithms. Moreover, unlike many other FR techniques, they do not require any extra training information, such as the view angle. These advantages make them practical to implement under uncontrolled conditions. The proposed algorithms are tested on three large face databases with vast variations and achieve superior performance compared with other 12 existing FR techniques.

The effect of the category of sport team on the role of nostalgia in an individual supporter’s psychological connection to that sport team

With the many benefits related to high levels of psychological connection with a sport team, marketers, management and communities desire supporters to be highly connected with sport teams. A major gap has been identified in relation to the effect of the category of sport team on the role of nostalgia in determining that connection. A conceptual model is presented together with a proposed methodology. This research will aid academics and administrators in their communications with and targeting of consumers and affords communities the opportunity to benefit from consumers’ higher levels of psychological connection with a sport team.

Ethical evaluations and behavioural intentions of early career accountants : the impact of mentors, peers and individual attributes

This study examined how mentoring support, peer influence and individual attributes of early career accountants (ECA) influence their ethical evaluations and behavioural intentions. Respondents indicate that their evaluation of the seriousness of the ethical conflict is affected by the perceived standard of ethical conduct of their peers, their personal ethical orientation, the extent of ethics education at university, and gender. ECAs' evaluation of a senior colleague's unethical behaviour is affected by mentoring support and the perceived standard of ethical conduct of peers. In terms of ECAs' willingness to contact accounting professional bodies for ethical advice, the size of the accounting firm and the extent of their ethics education at university are significant factors. Furthermore, the likelihood of respondents choosing a more ethical decision is correlated with his or her individual ethical orientation and the extent of ethics education at university.

Individual, social and environmental determinants of participation in physical activity for prostate cancer survivors

Participation in physical activity helps prostate cancer survivors to cope with the side effects of treatment, enhances quality of life and decreases the risks of many of the comorbidities to which survivors are highly susceptible. Prostate cancer survivors, however, are less likely than other cancer survivors (e.g., breast and colorectal) to increase physical activity after diagnosis. Interventions have been only modestly successful at increasing participation in physical activity for prostate cancers survivors and more research is needed to increase our understanding of the determinants of physical activity for this group. Using a social ecological framework, this qualitative research sought to examine the individual, social and environmental determinants of participation in physical activity for prostate cancer survivors. In-depth interviews were conducted with 20 survivors of prostate cancer aged between 35 and 75 years. Participants were drawn from a public and a private health service and from a range of treatment types. We are currently collecting data for this study and preliminary themes will be discussed at the conference (abstract will be updated once findings are known).

Sexual selection and individual genetic diversity in a songbird

Here, we report for the first time, to our knowledge, a strong correlation between a measure of individual genetic diversity and song complexity, a sexually selected male trait in sedge warblers, Acrocephalus schoenobaenus. We also find that females prefer to mate with males who will maximize this diversity in individual progeny. The genetic diversity of each offspring is further increased by means of nonrandom fertilization, as we also show that the fertilizing sperm contains a haplotype more genetically distant to that of the egg than expected by chance. These findings suggest that species' mating preferences may be subject to fine tuning aimed at increasing offspring viability through increased genetic diversity. This includes external and internal mechanisms of selection, even within the ejaculate of a single male.

Estimation of in vitro prebiotic activity of individual and mixed dietary fibres

Background: Epidemiological studies have demonstrated a link between dietary fibre deficiency and prevalence of many “Western diseases” particularly colon related diseases. Many of the health benefits associated with dietary fibre are attributed to their prebiotic effect. However, not all fibres have the same prebiotic potential or the same impact on colon health.

Objective: To examine the in vitro fermentation properties of individual and mixed dietary fibres by measuring fermentation byproducts over time.

Design: Wheat bran and guar gum were selected for this study. Individual and mixed dietary fibres were added to batch fermentation system and were inoculated with fresh faecal inoculum (n= 4). Positive (inulin) and negative (no substrate) fermenters were also used to determine the differences. The pH of the five fermenters was adjusted to a baseline of 5.5 and 6.8 representing the pH of the proximal and distal sections of the colon respectively. Samples were drawn out of the fermenters at 0, 3, 9 and 24 hours for the analysis of pH, ammonia and short chain fatty acids (SCFAs).

Outcomes: There were no significant differences in the pH levels at various time points between fermenters adjusted to pH 5.5 at baseline. However, in fermenters adjusted to pH 6.8 the pH of the fermenter containing wheat bran increased over the time (24h (P = 0.017)) due to production of a high amount of ammonia. The total SCFAs production was greater in fermenters containing combined fibres.

Conclusion: There is a large inter-individual variation in the prebiotic effect of all types of dietary fibres, however, in the present study, dietary fibre combinations showed greater prebiotic potential compared with the individual fibres.
