Practices of alternative schools in Queensland in supporting Aboriginal and Torres Strait Islander young people to remain engaged in education

Alternative schools are an emerging model of education offered to young people who have been disenfranchised from conventional schooling opportunities. The body of literature on alternative schools in Australia has not identified how many Indigenous young people are engaged with alternative schools and how alternative schools are supporting Indigenous young people to remain engaged in education. It is well documented that Aboriginal and Torres Strait Islander people experience significant disadvantage including poorer educational outcomes than their non-Indigenous peers. This study seeks to contribute to improving educational outcomes for Aboriginal and Torres Strait Islander young people through exploring Aboriginal and Torres Strait Islander interactions with alternative schools in Queensland and investigating the practices of alternative school leaders in terms of how they are supporting Indigenous young people to remain engaged in education. Critical race theory informed the development of this study. An Aboriginal researcher sought to shift the focus of this study away from Indigenous young people to Principals; to explore their perspective of their own knowledge and practices in supporting Aboriginal and Torres Strait Islander young people at their school. Using survey methodology, a web-based questionnaire was developed to survey Principals’ providing data on alternative schools in Queensland including the demographics of the alternative school; self-reported knowledge of Indigenous cultures and communities and practices that support Aboriginal and Torres Strait Islander young people at their alternative school. There are nine key findings that emerged through the analysis of this study: key finding one is the high percentage of Aboriginal and Torres Strait Islander young people enrolled in schools surveyed; key finding two is there is a high percentage of Aboriginal and Torres Strait Islander staff employed in the schools; key finding three is the majority of the schools are located in low socio-economic areas; key finding four is the strong willingness of Principals’ in this study to engage in self-directed learning in relation to Aboriginal and Torres Strait Islander cultures; key finding five is the limited demonstration of understandings of Aboriginal and Torres Strait Islander cultures and communities; key finding six is the most prevalent practice of Principals’ in this study is the celebration of cultural events and cultural activities; key finding seven is the limited Principal engagement with Aboriginal and Torres Strait Islander young people, their families and the local community; key finding eight is the practice of alternative schools provides limited support and nurturing of Aboriginal and Torres Strait Islander young person’s cultural identity and key finding nine is that Principals’ are relying heavily on informal discussions with staff to know what their staff’s knowledge and skills are in relation to supporting Aboriginal and Torres Strait Islander young people. There are multiple implications that have arisen from this study. The data demonstrated high numbers of Aboriginal and Torre Strait Islander students and staff. The data also revealed that Principal’s demonstration of knowledge in relation to Indigenous cultures and communities was limited, as well as limited Principal engagement with Indigenous young peoples, families and communities. Therefore a major practical implication of this study is the urgent need for quality cultural learning opportunities for leaders of alternative schools to improve practices. Additionally, the implications of this study support an urgent need for further research on the role alternative schools are playing in supporting Indigenous young people to remain engaged in education.

Fatty acid synthesis and pyruvate metabolism pathways remain active in dihydroartemisinin induced dormant ring stages of Plasmodium falciparum

Artemisinin (ART) based combination therapy (ACT) is used as the first line treatment of uncomplicated falciparum malaria worldwide. However, despite high potency and rapid action there is a high rate of recrudescence associated with ART monotherapy or ACT long before the recent emergence of ART resistance. ART induced ring stage dormancy and recovery has been implicated as possible cause of recrudescence; however, little is known about the characteristics of dormant parasites including whether dormant parasites are metabolically active. We investigated the transcription of 12 genes encoding key enzymes in various metabolic pathways in P. falciparum during dihydroartemisinin (DHA) induced dormancy and recovery. Transcription analysis showed an immediate down regulation for 10 genes following exposure to DHA, but continued transcription of 2 genes encoding apicoplast and mitochondrial proteins. Transcription of several additional genes encoding apicoplast and mitochondrial proteins, particularly genes encoding enzymes in pyruvate metabolism and fatty acid synthesis pathways, were also maintained. Additions of inhibitors for biotin acetyl CoA carbozylase and enoyl-acyl carrier reductase of the fatty acid synthesis pathways delayed the recovery of dormant parasites by 6 and 4 days, respectively following DHA treatment. Our results demonstrate most metabolic pathways are down regulated in DHA induced dormant parasites. In contrast fatty acid and pyruvate metabolic pathways remain active. These findings highlight new targets to interrupt recovery of parasites from ART-induced dormancy and to reduce the rate of recrudescence following ART treatment.

Higher intensity exercise helps cancer survivors remain motivated

Purpose The aim of the present study was to determine if exercise intensity impacts upon the psychosocial responses of breast and prostate cancer survivors to a rehabilitation program. Methods Eighty-seven prostate and 72 breast cancer survivors participated in an 8-week exercise and supportive group psychotherapy intervention (n=84) or control (n=75) group. Intervention participants were randomized to low-to-moderate intensity exercise (LIG; n=44; 60–65 % VO2peak, 50–65 % one repetition maximum (1RM)) or moderate-to-high intensity exercise (HIG; n=40; 75–80 % VO2peak, 65–80 % 1RM) while controls continued usual care. Before and after the 8 weeks, all participants completed the Functional Assessment of Cancer Therapy-Breast or -Prostate to assess quality of life (QOL) and Behavioural Regulations of Exercise Version 2 for exercise motivation. Intervention participants also completed a follow-up assessment 4 months post-intervention. Results All three groups improved in QOL from baseline to post-intervention, with no significant differences. From postintervention to follow-up, the LIG and HIG similarly maintained QOL scores. Between baseline and post-intervention, both intervention arms improved their motivation to exercise compared to the controls (p=0.004). At the 4-month followup, the HIG had maintained their overall exercise motivation (p<0.001) and both domains of intrinsic motivation (identified regulation, p=0.047; intrinsic regulation, p=0.007); however, the LIG had regressed. Conclusions The structured intervention was successful at improving autonomous exercise motivation, regardless of exercise intensity. However, only those participants who had exercised at a higher intensity sustained their improvement. Intervention participation did not improve QOL more than controls. Implications for Cancer Survivors Higher-intensity exercise is more likely to result in more sustainable increases in motivation to exercise among cancer survivors.

Increasing Knowledge Focus - a Means for Entrepreneurs to Remain on a Growth Path: Essays on the Role and Nature of Knowledge Management in Finnish SMEs (summary section only)

This study explores the role and nature of knowledge management (KM) in small and medium-sized companies (SMEs). Even though the role of knowledge as a competitive advantage is commonly recognized in the SME sector, almost no attention has been paid to the managing and developing of knowledge in SMEs. This thesis consists of three different sub-studies that were reported in four individual essays. The results of the questionnaire study indicate that nearly all companies that responded to the questionnaire (N = 108) found intangible assets, i.e. knowledge resources to be their main source of competitive advantage. However, only less than a third of the companies actively deal with knowledge management. The results also indicate a significant correlation between activity in knowledge management and sustainable organic growth of the company. The interview study (N = 10) explored the context and motives of the SMEs for managing their intangible assets, and the concrete practices of knowledge management. It turned out that KM facilitated change management, clarification of the vision and new strategy formulation. All the interviewed companies were aiming at improved innovation process, new ways of doing business and attaining an increased “knowledge focus” in their business. Nearly all also aspired to grow significantly. Thus, KM provides a strategy for these SMEs to guarantee their survival and sustainability in the turbulent markets. The action research was a process to assess and develop intangible resources in three companies. The experienced benefits were the clarification of future focus and strategy, creation of a common language to discuss strategic issues within the company, as well as improved balance of different categories of intangible assets. After the process all the case companies had developed in the chosen key areas. Thus, by systematic knowledge management the implementation of new strategic orientation (knowledge focusing) was facilitated. The findings can be summarized in two main points. First, knowledge management seems to serve the purpose of change, renewal and new strategic orientation in the SMEs. It also seems to be closely related to organic growth and innovation. All of these factors can be considered dimensions of entrepreneurship. Second, the conscious development of intangible assets can increase the balance of different categories of intangible assets and the overall knowledge focusing of business. In the case companies, this in turn facilitated the path to the improved overall performance.

Compressed Metal Powders that Remain Superhydrophobic After Abrasion

Superhydrophobic “lotus effect” materials are typically not sufficiently robust for most real world applications because their small surface features are both easily damaged and vulnerable to fouling. Here, a method for preparing a new type of superhydrophobic (? > 162°) composite material by compression of superhydrophobic metal particles is reported. This material, which has no natural analogue, has low-surface-energy microstructures extending throughout its whole volume. Removing its outer layer by abrasion or cutting deep into it does not result in loss of superhydrophobicity because it merely exposes a fresh portion of the underlying superhydrophobic material. The high contact angle is therefore retained even after accidental damage, and vigorous abrasion can be used to restore hydrophobicity after fouling.

Proteomics on porcine haptoglobin and IgG/IgA show protein species distribution and glycosylation pattern to remain similar in PCV2-SD infection

Haptoglobin (Hp) and immunoglobulins are plasma glycoproteins involved in the immune reaction of the organism after infection and/or inflammation. Porcine circovirus type 2-systemic disease (PCV2-SD), formerly known as postweaning multisystemic wasting syndrome (PMWS), is a globally spread pig disease of great economic impact. PCV2-SD affects the immunological system of pigs causing immunosuppression. The aim of this work was to characterize the Hp protein species of healthy and PCV2-SD affected pigs, as well as the protein backbone and the glycan chain composition of porcine Hp. PCV2-SD affected pigs had an increased overall Hp level, but it did not affect the ratio between Hp species. Glycoproteomic analysis of the Hp β subunits confirmed that porcine Hp is N-glycosylated and, unexpectedly, O-glycosylated, a PTM that is not found on Hp from healthy humans. The glyco-profile of porcine IgG and IgA heavy chains was also characterized; decreased levels of both proteins were found in the investigated group of PCV2-SD affected pigs. Obtained results indicate that no significant changes in the N- and O-glycosylation patterns of these major porcine plasma glycoproteins were detectable between healthy and PCV2-SD affected animals.

Serum amyloid A-related inflammation is lowered by increased fruit and vegetable intake, while high-sensitive C-reactive protein, IL-6 and E-selectin remain unresponsive

The present study assessed whether increased fruit and vegetable (F&V) intake reduced the concentrations of the inflammatory marker serum amyloid A (SAA) in serum, HDL2 and HDL3 and whether the latter reduction influenced any of the functional properties of these HDL subfractions. The present study utilised samples from two previous studies: (1) the FAVRIT (Fruit and Vegetable Randomised Intervention Trial) study - hypertensive subjects (systolic blood pressure (BP) range 140-190 mmHg; diastolic BP range 90-110 mmHg) were randomised to receive a 1-, 3- or 6-portion F&V/d intervention for 8 weeks, and (2) the ADIT (Ageing and Dietary Intervention Trial) study - older subjects (65-85 years) were randomised to receive a 2- or 5-portion F&V/d intervention for 16 weeks. HDL2 and HDL3 were isolated by rapid ultracentrifugation. Measurements included the following: serum high-sensitive C-reactive protein (hsCRP) by an immunoturbidimetric assay; serum IL-6 and E-selectin and serum-, HDL2- and HDL3-SAA by ELISA procedures; serum-, HDL2- and HDL3-cholesterol ester transfer protein (CETP) activity by a fluorometric assay. Although the concentrations of hsCRP, IL-6 and E-selectin were unaffected by increasing F&V intake in both studies (P>0·05 for all comparisons), those of SAA in HDL3 decreased in the FAVRIT cohort (P= 0·049) and those in HDL2 and HDL3 decreased in the ADIT cohort (P= 0·035 and 0·032), which was accompanied by a decrease in the activity of CETP in HDL3 in the FAVRIT cohort (P= 0·010) and in HDL2 in the ADIT cohort (P= 0·030). These results indicate that SAA responds to increased F&V intake, while other inflammatory markers remain unresponsive, and this leads to changes in HDL2 and HDL3, which may influence their antiatherogenic potential. Overall, the present study provides tangible evidence of the effectiveness of increased F&V intake, which may be of use to health policy makers and the general public.

The Limits of Local Accommodation: Why Contentious Events Remain Prone to Conflict in Northern Ireland

This article examines the difficulties of finding local solutions to the problem of contentious events in contemporary Northern Ireland. In so doing, it offers a sociological perspective on fundamental divisions in Northern Ireland: between classes and between communities. It shows how its chosen case study—parades and associated protests in north Belfast—exemplifies the most fundamental problem that endures in post-Agreement Northern Ireland, namely that political authority is not derived from a common civic culture (as is the norm in Western liberal democracy) but rather that legitimacy is still founded on the basis of the culture of either one or the other community. Haugaard’s reflections on authority and legitimacy are used to explore Northern Ireland’s atypical experience of political conflict vis-`a-vis the Western liberal democratic model. The Bourdieusian concepts of field illusio and doxa help to explain why it is that parading remains such an important political and symbolic touchstone in this society.

Moving on, not out: when young people remain homeless

This article explores the contours of continued housing instability among a group of young people who are participants in a qualitative longitudinal study of youth homelessness in Dublin, Ireland, and considers the limitations of the ‘acculturation’ thesis in explaining long-term homelessness amongst the young. Baseline interviews were conducted with 40 young people, aged 14–23 years, in 2004, and follow-up interviews were conducted with 30 research participants successfully ‘tracked’ in 2005–06. By the time of follow-up, 17 of those interviewed had exited homelessness and 13 remained homeless. The article focuses on the latter group with the aim of exploring the processes and experiences associated with their continued homelessness. The findings presented demonstrate the adverse impact of their ongoing movement through emergency services targeting the under-18s, including their greater immersion in drug and criminal lifestyles. A majority had experienced one or more period of incarceration by the time of follow-up, and many were users of adult homeless services. Whilst some dimensions of young people's accounts are suggestive of a process of acculturation to street and hostel life, we argue that their continued homelessness is better explained as a consequence of their ongoing and unresolved transience and, in particular, their continued dependence on emergency hostel accommodation. The implications of the findings for policy and service provision for homeless young people are discussed.

"They always remain girls" : la re/production des rapports de genre dans les sports féminins au Québec, 1919-1961

Cette thèse lève en partie le voile sur l’histoire des sports féminins au Québec de 1919 à 1961, soit de l’âge d’or des sports féminins au Canada jusqu’à l’adoption de la Loi sur la condition physique et le sport amateur par le gouvernement fédéral. Elle montre comment les rapports de genre ont été re/produits dans les sports féminins en étudiant les discours et les pratiques, tout en portant une attention particulière à l’influence qu’exercent l’appartenance de classe, l’ethnicité et la religion sur les sports féminins. L’analyse se penche d’abord sur les discours des médecins, des professeurs d’éducation physique et des clercs de l’Église catholique pour étudier les prescriptions qu’ils ont formulées à l’égard de la participation sportive des femmes. Les idées de deux Montréalaises, Myrtle Cook et Cécile Grenier, sont ensuite examinées pour montrer comment elles contestent les discours dominants. Enfin, les pratiques sportives des femmes dans deux centres sportifs montréalais, soit la Palestre nationale et le Young Women’s Christian Association, ont été étudiées de manière détaillée afin de mettre en lumière les différences, mais aussi certaines similitudes, entre l’organisation des sports féminins dans les communautés francophones et anglophones de la ville. Cette thèse met en évidence les tensions qui découlent des rapports de genre, de classe, d’ethnicité et de l’appartenance religieuse, et qui sont présentes à la fois dans les discours et les pratiques. Comme ailleurs en Amérique du Nord et même ailleurs en Occident, les discours dominants au Québec ne sont pas univoques, alors que des vues divergentes les contestent et que les pratiques sont plurielles. Tout en s’inscrivant dans le mouvement plus large d’accès des femmes aux sports en Occident, les discours et les pratiques observables à Montréal s’en distinguent, notamment par la forte influence de l’Église catholique et par les tensions ethniques. Le Québec est donc un cas d’espèce tout indiqué pour mettre en lumière la complexité de la re/production des rapports de genre à travers l’analyse des sports féminins, l’étude de ce champ constituant en même temps une avenue de recherche fort stimulante pour mieux saisir l’entrée de la province dans la modernité.

Did Gold Remain Relevant in the Post-1971 International Monetary System?

The central hypothesis to be tested is the relevance of gold in the determination of the value of the US dollar as an international reserve currency after 1971. In the first section the market value of the US dollar is analysed by looking at new forms of value (financial derivative products), the dollar as a safe haven, the choice of a standard of value and the role of SDRs in reforming the international monetary system. Based on dimensional analysis, the second section analyses the definition and meaning of a numéraire for international currency and the justification for a variable standard of value based on a commodity (gold). The second section is the theoretical foundation for the empirical and econometric analysis in the third and fourth sections. The third section is devoted to the specification of an econometric model and a graphical analysis of the data. It is clear that an inverse relation exists between the value of the US dollar and the price of gold. The fourth section shows the estimations of the different specifications of the model including linear regression and cointegration analysis. The most important econometric result is that the null hypothesis is rejected in favour of a significant link between the price of gold and the value of the US dollar. There is also a positive relationship between gold price and inflation. An inverse statistically significant relation between gold price and monetary policy is shown by applying a dynamic model of cointegration with lags.
