Saw palmetto supplement use and prostate cancer risk

Saw palmetto is an herb used to treat the symptoms of benign prostatic hyperplasia. In vitro studies have found that saw palmetto inhibits growth of prostatic cancer cells and may induce apoptosis. To evaluate whether saw palmetto supplements are associated with a reduced risk of prostate cancer, we conducted a prospective cohort study of 35,171 men aged 50-76 yr in western Washington state. Subjects completed questionnaires between 2000 and 2002 on frequency of use of saw palmetto supplements and saw palmetto-containing multivitamins over the previous 10 yr in addition to other information on supplement intake, medical history, and demographics. Men were followed through December 2003 (mean of 2.3 yr of follow-up) via the western Washington Surveillance, Epidemiology, and End Results cancer registry, during which time 580 developed prostate cancer. Ten percent of the cohort used saw palmetto at least once per week for a year in the 10 yr before baseline. No association was found between this level of use of saw palmetto and risk of prostate cancer development [hazard ratio (HR) = 0.95; 95% confidence interval = 0.74-1.23] or with increasing frequency or duration of use. In this free-living population, use of commercial saw palmetto, which varies widely in dose and constituent ratios, was not associated with prostate cancer risk.

Arts curriculum reform : social and cultural reproduction in Victorian schools

This thesis examines the implementation of the government educational policy document The Curriculum and Standards Framework. I examined the historical and political motivation behind the development of this document and how it introduced a pervasive new initiative of outcomes based education and accountability based on economic rationalism. In particular I examined the implications this new approach had for visual arts education and the subsequent changes to the arts curriculum. This has entailed the introduction of the aesthetic appreciation of the arts as an outcome of the CSF: The Arts. I applied Bourdieu's theory of cultural reproduction in education which draws predominantly on a Weberian view and a theory of practice. Bourdieu discusses differential educational achievement according to cultural capital stating education requires certain forms of cultural capital that are not equally distributed among the classes. This therefore impedes or enhances life chances according to social class i.e. educational qualifications become a commodity in the labour market and other social fields. I examined how aesthetic appreciation of the arts has evolved historically as a form of social distinction. This entails an abstract element of arts discourse, which demands a certain linguistic competence, and familiarisation, which Bourdieu claims, is developed in the family, as 'cultural capital' this is further perpetuated in schools. The likely outcome is that the introduction of aesthetic appreciation in arts education i.e the demand to 'write about' and 'talk about' art, will perpetuate class inequality due to social and cultural difference. The study has been to examine the practices of arts education in four schools and the extent to which aesthetic appreciation was implemented in the visual arts. Data was collected by case study methods of observation, questionnaire and interview and was interpretive in both quantitative and qualitative methods. I analysed the data based on class differentiation by socioeconomic divisions and examined the school ethos and attitude towards the Arts along with differentiation in cultural capital between student population. I also found teacher and student habitus played a vital role in the implementation of the CSF. This is because habitus can cause resistance to change due to the division between the formulation of the curriculum in the bureaucratic order and the practice of teachers in classrooms. My thesis interprets education as a form of social reproduction, perpetuating the existing social order. However, as Bourdieu asserts and I agree education is a form of symbolic power as it conceals its social function under the guise of neutrality and the technical functional premise. Therefore, this thesis aims to make transparent how the education system serves the interests of the dominant group through curriculum policy. Consequently, it becomes clear how education has far reaching social implications where the distinctions of class are perpetuated through cultural reproduction.

Sustaining collaborations : creative research and cross-cultural engagement

Increasingly, the linear, instrumentalist and culturally hegemonic character of dominant sustainability discourse is under critique, with the term accruing new or expanded associations that challenge the its future-oriented, temporally stable, and ontologically determinate history. In Australia, these shifts take in a recognition that indigenous Australian understandings of and relationships with the environment profoundly challenge the generic claims of sustainability applied to both theory and practice. But how do these radically different and still marginal understandings actually enter into the process of producing sustainable designs on the world? This paper will report on the beginnings of a collaborative project that seeks to advance a proposal for an Aboriginal cultural precinct in the heart of Melbourne. This project's intention is to develop innovative methods for consultation and participation through collaborative creative research between Aboriginal artists and academic architects. The paper will discuss this method as a strategy for moving beyond traditional modes of cross-cultural engagement in the design and construction of sustainable cultural precincts.

Do young children get the message? The effects of repeated video viewing on explicit and implicit information

The aim of this study was to explore the effects of repeat viewing on comprehension of explicitly and implicitly presented information in an animated movie. Seventy-three pre-school children watched an animated film and were tested for comprehension after either their single or fifth viewing. Only children’s comprehension of explicitly presented information was facilitated by repeat viewing. However, post hoc analyses revealed that children’s explicit and implicit comprehension of a central character Thunderbolt significantly increased across viewing conditions, whereas, repeat viewing only facilitated children’s explicit comprehension of the central character Patch. The theoretical and practical implications of these findings are discussed.

How do teachers investigate scientific concepts in an Early Childhood Environment?

Early Childhood Educators have an important role to fulfil in aiding children's development and understandings in the science curriculum. There are many different views and opinions on how science can be taught in an Early Childhood environment, it is therefore our aim to investigate how teachers feel about teaching science concepts and promoting science in the early childhood centre. We aim to discover how everyday activities relate to the nature of science within our everyday lives. The science curriculum is important in Early Childhood settings as it provides children with various opportunities to explore the natural world. We are hoping to gain a deeper understanding of how teachers are guiding and encouraging children to make sense of their experiences. It is also important that we explore how Early Childhood Educators understand their own practice in teaching science concepts in their curriculum.

Description of project: We will be completing a small inquiry based task which will require us to compile data collected from interviews, recordings from teachers in long day and kindergarten settings around the Geelong region.

Methodology: ln order to undertake this research we will be using a socio cultural framework, focusing on language in the social environment and play (basing our ideas on the theories of Vygotsky). We will be undertaking narrative accounts to obtain data which will be collated from three different sources.

Ethical implications of projects: We do not foresee any significant risks to any participant in this study. The topic of the research is uncontroversial, and we will be taking measures to ensure anonymity or confidentiality where appropriate.
