Excessive alcohol use and its association with risky sexual behaviour: a cross-sectional analysis of data from Victorian secondary school students

Objective
Estimate the prevalence of sexual behaviour and alcohol use and examine the association between excessive alcohol use and risky sexual behaviour in late secondary students in Victoria, Australia.

Method
The sample of Year 11 students from government and independent schools participating in the 2008 International Youth Development Study (n=450) was representative of the Victorian school population. Logistic regression analyses examined the associations between sexual behaviour, binge and compulsive drinking, adjusting for socio-demographic, school and family factors.

Results
Under half (44%) the students had experienced sex in the past year, half (50%) had engaged in binge drinking in the past two weeks and 26% reported compulsive drinking in the past year. Of those who reported sex in the past year (n=197), 34% had sex without a condom at the last sexual encounter and 28% later regretted sex due to alcohol. The likelihood of experiencing sex was increased by binge (OR=2.44, 95%CI 1.44-4.12) and compulsive drinking (OR=2.15, 95%CI 1.29-3.60). For those sexually active, binge drinking increased the risk of having three or more sexual partners (OR=3.37, 95%CI 1.11-10.26) and compulsive drinking increased the likelihood of regretted sex due to alcohol (OR=4.43, 95%CI 2.10-9.31). Excessive drinking was not associated with condom non-use.

Conclusion and implications
Risky sex – multiple sexual partners and regretted sex due to alcohol – and excessive drinking are highly prevalent and co-associated among Victorian late secondary students.

Cannabis use and related harms in the transition to young adulthood: a longitudinal study of Australian secondary school students

The current study documents the changing rates of cannabis use, misuse and cannabis-related social harms among Australian adolescents as they grow into young adulthood. It utilised data from a longitudinal study of young people at ages 15, 16, 17, and 19. The rates of cannabis use were found to increase as participants aged; past year use increased from 7.5% at age 15 to 29.8% at age 19. Further, at ages 17 and 19, cannabis use was more prevalent among males than females. Among those who reported cannabis use, the rates of cannabis-related harms were low to moderate, and did not increase with age in the same manner as rates of cannabis use. The most prevalent self-reported cannabis-related harm was anxiety/depression; affecting between 20–30% of the cannabis users at each age. These findings may assist in understanding the extent of cannabis-related problems among youth, and in planning relevant services.

What works in secondary schools? A systematic review of classroom-based body image programs

Governments, schools, and curriculum authorities are increasingly recognizing that body image during adolescence is a public health issue that warrants attention in the school setting. After 30 years of eating disorder prevention research, and given the current interest in this area, it seems timely to review the research on interventions to improve body image in schools. We reviewed universal-selective, classroom-based programs that have been conducted since the year 2000, among adolescents, and found 16 eligible intervention programs. Seven of these programs were effective in improving body image on at least one measure, from pre to post test, though effect sizes were small (d = 0.22–0.48). These effective programs were conducted among younger adolescents 12.33–13.62 years, and included activities focusing on media literacy, self esteem, and the influence of peers. Implications for school personnel and curriculum authorities are discussed, and we provide recommendations for a strategic approach to future research in this area.

Contributions of school design to adolescent identity formation : case studies of four Australian secondary schools

The paper presents a summary of the study that examined the relationship between school design and adolescent identity formation. Reviewing theories and empirical studies of identity development, three major processes involved in adolescent identity formation were identified: (1) separation or individuation process, (2) social integration or relational connectedness, and (3) developmental exploration. Two key characteristics of schools that support these identity formation processes were proposed: (1) having a supportive environment addressing needs for individuation and social integration, and (2) providing opportunities for developmental exploration. Implications of these characteristics for school design were studied through a review of research and practices of learning space design. Four secondary schools in Australia which represented an innovative approach to learning space design were then examined to provide insights into these design-related implications and better understand issues and challenges associated with them. The paper concludes with proposing five design principles which supports adolescent identity development through contributing to processes involved in identity formation.

Transfection of MDA-MB-231 human breast carcinoma cells with bone sialoprotein (BSP) stimulates migration and invasion in vitro and growth of primary and secondary tumors in nude mice

We have investigated the role of bone sialoprotein (BSP), a secreted glycoprotein normally found in bone, in breast cancer progression. To explore functions for BSP in human breast cancer invasion and metastasis, the full-length BSP cDNA was transfected into the MDA-MB-231-BAG human breast cancer cell line under the control of the CMV promoter. Clones expressing BSP and vector control clones were isolated. BSP producing clones showed increased monolayer wound healing, a faster rate of stellate outgrowth in Matrigel and increased rate of invasion into a collagen matrix when compared to control clones. Clones were also examined in models of breast cancer growth and metastasis in vivo. BSP transfected clones showed an increased rate of primary tumor growth following mammary fat pad injection of nude mice. BSP transfected clones and vector control clones metastasized to soft organs and bone at a similar rate after intra-cardiac injection as determined by real-time PCR and X-ray analysis. Although these organs were targets for both BSP transfected and non-transfected cells, the size of the metastatic lesion was shown to be significantly larger for BSP expressing clones. This was determined by real-time PCR analysis for soft organs and by X-ray analysis of bone lesions. For bone this was confirmed by intra-tibial injections of cells in nude mice. We conclude that BSP acts to drive primary and secondary tumor growth of breast cancers in vivo.

Secondary English in the Australian curriculum: Tasmanian teachers’ perceptions of implementation – a conceptual overview

Australian school curricula are currently being reformed with the nation-wide introduction of the Australian Curriculum, designed to bring national subject content and assessment standard conformity through the detailing of the “core knowledge, understanding, skills and general capabilities [that are deemed] important for all Australian students” (Australian Curriculum, Assessment and Reporting Authority [ACARA], 2008). The reform and implementation of any curriculum requires well- structured planning, and at the school level, curriculum implementation requires the input of teachers – the frontline stakeholders. Research suggests that the implementation of a new curriculum requires concentrated support to ensure that teachers are able to work and progress through professional learning effectively (Mulford, 2008; Australian Curriculum Coalition, 2010). This chapter is presented in two parts: a discussion about the incoming Australian Curriculum: English, and an outline of a proposed qualitative case study that will examine English teachers’ perceptions of the implementation of the Australian Curriculum: English in Tasmania.

Accessibility and autonomy preconditions to ‘our’ inclusion: a grounded theory study of the experiences of secondary students with vision impairment

In this paper, I report core findings of a small-scale qualitative study that I conducted with a group of young people with vision impairment who attended an inclusive secondary school in the Australian state of Queensland. My objective was to capture their voiced experiences of their schooling through face-to-face interviews and to develop a substantive theory that was grounded in the collected data. Relevant to the study was my status as an insider researcher, which impacted both data collection and analysis. Here, I develop the methodological process that I followed and present core findings of the study. These findings shed light on the practices within schools that are designed to promote inclusion yet perpetuate exclusion for students with impaired vision.

Maximising students' use of purpose-built shade in secondary schools: Quantitative and qualitative results of a built-environment intervention

A trial installing shade sails at secondary schools found increased students' use of newly shaded areas, but relatively low use overall. We examined site features and weather related to use of these shaded areas. Tables with seats and temperatures ≥27 °C increased student use of shaded areas, presence of grass decreased use. Focus groups at eight schools suggest students were unaware of changes to their habitual use of favoured locations. Results infer careful selection of locations for built-shade and provision of tables with seats will assist in maximising student use and investments in shade sails.

Action research into social media within secondary school classes

Gail used social and participatory media in the secondary school classroom, not just to engage students but also to enhance their learning. Her action research successfully used concepts of formal and informal learning as well as peer review and peer/self-assessment. For the teacher, unlearning many previous practices became essential.
