Why we interview now-reflexivity and perspective in a longitudinal study

This paper discusses a longitudinal, interview-based study of Australian secondary school students that explores the interaction between school ethos and forms of subjectivity. The study was designed to enable prospective and retrospective understandings of identity over time. It is suggested that this methodology encourages a reflexive self-positioning for both participants and researchers and, in the accumulation of an archive of perspectives, responds to poststructuralist critiques of contingency and construction in research interviews. Second, it is argued that the richness of longitudinal research invites more than one kind of analysis, and that working with and across conventionally divergent theoretical approaches can be fruitful. This is discussed with reference to Bourdieu's account of social field and habitus, and Hollway and Jefferson's notion of the 'defended subject'.

A window for a purpose: developing a framework for describing effective science teaching and learning

This paper describes the development of a framework – the SIS Components – for describing effective teaching and learning in science, to support a system wide change initiative. The methodology used and the analysis that led to their refinement, is traced to expose the different issues involved in constructing the notion of lsquoeffective practice.rsquo These issues have to do with purpose, politics and audience. They determine features of the framework such as specificity, elements focused on, and the support structures that are put in place to establish the particular discourse being promoted. The paper describes the different research methods used to establish, to promote and to validate the components, and outlines the different senses in which this and any framework can be seen as contingent on the setting for which it is intended.

Building health promoting work settings : identifying the relationship between work characteristics and occupational stress in Australia

Occupational stress is a serious threat to the health of individual workers, their families and the community at large. The settings approach to health promotion offers valuable opportunities for developing comprehensive strategies to prevent and reduce job stress. However, there is evidence that many workplace health promotion programs adopt traditional, lifestyle-oriented strategies when dealing with occupational stress, and ignore the impact that the setting itself has on the health of employees. The aim of the present study was to address two of the barriers to adopting the settings approach; namely the lack of information on how psycho-social work characteristics can influence health, and not having the confidence or knowledge to identify or address organizational-level issues. A comprehensive occupational stress audit involving qualitative and quantitative research methods was undertaken in a small- to medium-sized public sector organization in Australia. The results revealed that the work characteristics ‘social support’ and ‘job control’ accounted for large proportions of explained variance in job satisfaction and psychological health. In addition to these generic variables, several job-specific stressors were found to be predictive of the strain experienced by employees. When coupled with the results of other studies, these findings suggest that work characteristics (particularly control and support) offer valuable avenues for creating work settings that can protect and enhance employee health. The implications of the methods used to develop and complete the stress audit are also discussed.

Longitudinal relationships among overweight, life satisfaction, and aspirations in young women

Objective: This study investigated associations of overweight status and changes in overweight status over time with life satisfaction and future aspirations among a community sample of young women.
Research Methods and Procedures: A total of 7865 young women, initially 18 to 23 years of age, completed two surveys that were 4 years apart. These women provided data on their future life aspirations in the areas of further education, work/career, marital status, and children, as well as their satisfaction with achievements to date in a number of life domains. Women reported their height and weight and their sociodemographic characteristics, including current socioeconomic status (occupation).
Results: Young women's aspirations were cross-sectionally related to BMI category, such that obese women were less likely to aspire to further education, although this relationship seemed explained largely by current occupation. Even after adjusting for current occupation, young women who were obese were more dissatisfied with work/career/study, family relationships, partner relationships, and social activities. Weight status was also longitudinally associated with aspirations and life satisfaction. Women who were overweight or obese at both surveys were more likely than other women to aspire to "other" types of employment (including self-employed and unpaid work in the home) as opposed to full-time employment. They were also less likely to be satisfied with study or partner relationships. Women who resolved their overweight/obesity status were more likely to aspire to being childless than other women.
Discussion: These results suggest that being overweight/obese may have a lasting effect on young women's life satisfaction and their future life aspirations.

Faster, richer, better: rapid appraisal techniques for the study of IS implementation in virtual communities

A major issue in Information Systems (IS) research is how to combine relevance and rigor (Benbasat and Zmud, 1999) and reduce the widening gap between research results and adoption (Dunn, 1994). Qualitative researchers make use of interpretivist methods to add richness and depth to their understanding of user problems. Interpretivist methods applied to IS implementations can thus result in research which communicates those findings more effectively. However standard interpretivist data-collection and analysis methods can be time-consuming and expensive. Findings based on these methods may be irrelevant to practitioners by the time they reach publication stage. A potential solution to this problem lies in Rapid Appraisal or RA, a qualitative appraisal methodology derived from rural development-related research. It offers IS researchers an additional technique for learning and acquiring relevant information in a limited period of time that  supplements current data collection and analysis techniques. RA adds value to the traditional approach for studying diffusion of innovation, supporting and extending the IS researcher’s qualitative ‘tool-kit’. In this paper we review an electronic gateway designed to facilitate the diffusion of an Australian government to business [G2B] export documentation system, EXDOC, which was first implemented with meat producers. RA techniques were used to collect and analyse data regarding the implementation of the first regional Electronic Trade Facilitation Center [ETFC] successfully established for Australian exporters in the horticulture sector. The findings from the original EXDOC implementation in the meat sector were confirmed and extended through this study. These include the importance of developing a governance structure that ensures all community members share the benefits of an implementation and the fact that virtual trading communities are attractive to users only if they add value to their business and extend standard ways of operating. Interactive interviews, part of the RA approach; also enabled us to expand our understanding of the way in which procedures developed in the course of implementing an electronic market represent value-adding opportunities for virtual trading communities. The paper has special relevance for researchers investigating adoption and diffusion issues experienced by small-scale producers with low exposure to technology in remote and rural settings.

Association of family environment with children's television viewing and with low level of physical activity

Objective: This study examined associations between the family environment and children's television (TV) viewing and likelihood of being low-active.
Research Methods and Procedures: In 2001, children were recruited from 19 primary schools in Melbourne, Australia. Parents completed a questionnaire about their child's TV viewing and the family environment. Children also completed a questionnaire and wore an accelerometer for 8 days. Movement counts were used to identify low-active children (lowest quartile). Data were analyzed in May 2004.
Results: The sample consisted of 878 children (mean age = 11.5 0.6 yrs). Multiple logistic regression revealed that socioeconomic status [adjusted odds ratios (AOR) = 0.4 boys], frequency families watched TV together (AOR = 2.0 boys), mothers' (AOR = 1.8 boys; AOR = 2.5 girls) and fathers' (AOR = 2.6 boys; AOR = 2.8 girls) TV viewing, and rules prohibiting TV during mealtimes (AOR = 0.6 boys; AOR = 0.6 girls) related to children watching TV 2 h/d. Variables associated with low-level physical activity included self-reported enjoyment of Internet use (AOR = 1.7 boys) and preference for watching TV (AOR = 2.3 girls), perception that mother uses computer a lot (AOR = 1.9 boys) and likes using the computer (AOR = 0.6 girls), fathers' reported computer/electronic games use (AOR = 1.7 girls), frequency families used computer together (AOR = 0.4 girls), rules that TV viewing must be supervised (AOR = 1.9 boys; AOR = 0.6 girls), and having pay TV (AOR = 0.6 boys) and electronic games at home (AOR = 2.6 boys).
Discussion: These findings suggest that the relationships between the family environment and TV viewing and low-level activity are complex and that these behaviors are distinct.

Service provision factors that affect the health and wellbeing of people living in a lower SES environment: the perspective of service providers

Inequalities in health and wellbeing within low socioeconomic (SES)  environments are well documented. Factors inherent to the health care system itself, such as inaccessible, inflexible or inappropriate seroiceprovision, contribute to the poorer health status ofresidents oflow SES areas. This paper explores the issues ofseroice provision in low SES areas, documenting the perceptions of seroice providers about the seroice needs of residents, in order to understand the systemic factors that negatively impact on health and wellbeing. A total of54 health and welfare seroice providers from two adjacent low SES suburbs within regional Victoria were interoiewed using qualitative research methods. Keyfindings indicate that successful navigation of health care seroices by residents within these low SES environments is being impeded by issues ofaccess, a lack ofappropriate early interoention options or measures, and general resident disempowerment. Central to the improvement of seroice provision is the need for seroices to become economically, geographically and culturally accessible. In particular, the importance of community involvement in health planning and health promoting seroices must be reflected in the ethos ofseroice provision.

Managing contactability in telephone surveys

The Australian market research industry relies on telephone interviewing as one of its major data collection methods. Through Its LIST initiative, the industry has committed to best practice In research methods in order to address various concerns, especially the decline in response rates for telephone interviews. Response rates are determined by the co-operation of eligible respondents and their degree of contactabllity. The reported study is concerned with the way the industry attempts to manage contactabiIity. A study of fieldwork managers responSible for over 75% of all phone interviews in Australia revealed a limited use of contact enhancing strategies such as longer fieldwork periods and more callbacks. Commercial imperatives for timely surveys and a lack of end-user concern for response rate issues, along with cost issues, were believed to be responsible.

Differential regulation of Adiponectin receptor gene expression by Adiponectin and Leptin in Myotubes derived from obese and diabetic individuals

Objective: This study aimed to investigate the regulation of adiponectin receptors 1 (AdipoR1) and 2 (AdipoR2) gene expression in primary skeletal muscle myotubes, derived from human donors, after exposure to globular adiponectin (gAd) and leptin. Research Methods and Procedures: Four distinct primary cell culture groups were established [ Lean, Obese, Diabetic, Weight Loss (Wt Loss); n = 7 in each] from rectus abdominus muscle biopsies obtained from surgical patients. Differentiated myotube cultures were exposed to gAd (0.1 mug/mL) or leptin (2.5 mug/mL) for 6 hours. AdipoR1 and AdipoR2 gene expression was measured by real-time polymerase chain reaction analysis. Results: AdipoR1 mRNA expression in skeletal muscle myotubes derived from Lean subjects (p < 0.05) was stimulated 1.8-fold and 2.5-fold with gAd and leptin, respectively. No increase in AdipoR1 gene expression was measured in myotubes derived from Obese, Diabetic, or Wt Loss subjects. AdipoR2 mRNA expression was unaltered after gAd and leptin exposure in all myotube groups. Discussion: Adiponectin and leptin are rapid and potent stimulators of AdipoR1 in myotubes derived from lean healthy individuals. This effect was abolished in myotubes derived from obese, obese diabetic subjects, and obese-prone individuals who had lost significant weight after bariatric surgery. The incapacity of skeletal muscle of obese and diabetic individuals to respond to exogenous adiponectin and leptin may be further suppressed as a result of impaired regulation of the AdipoR1 gene.

Decreased expression of adipogenic genes in obese subjects with type 2 diabetes

Objective: Our objective was to delineate the potential role of adipogenesis in insulin resistance and type 2 diabetes. Obesity is characterized by an increase in adipose tissue mass resulting from enlargement of existing fat cells (hypertrophy) and/or from increased number of adipocytes (hyperplasia). The inability of the adipose tissue to recruit new fat cells may cause ectopic fat deposition and insulin resistance.

Research Methods and Procedures: We examined the expression of candidate genes involved in adipocyte proliferation and/or differentiation [ CCAAT/enhancer-binding protein (C/EBP) alpha, C/EBPdelta, GATA domain-binding protein 3 (GATA3), C/EBPbeta, peroxisome proliferator-activated receptor (PPAR) gamma2, signal transducer and activator of transcription 5A (STAT5A), Wnt-10b, tumor necrosis factor alpha, sterol regulatory element-binding protein 1c (SREBP1c), 11 beta-hydroxysteroid dehydrogenase, PPARG angiopoietin-related protein (PGAR), insulin-like growth factor 1, PPARitalic gamma coactivator 1alpha, PPARitalic gamma coactivator 1beta, and PPARdelta] in subcutaneous adipose tissue from 42 obese individuals with type 2 diabetes and 25 non-diabetic subjects matched for age and obesity.

Results: Insulin sensitivity was measured by a 3-hour 80 mU/m2 per minute hyperinsulinemic glucose clamp (100 mg/dL). As expected, subjects with type 2 diabetes had lower glucose disposal (4.9 plusminus 1.9 vs. 7.5 plusminus 2.8 mg/min per kilogram fat-free mass; p < 0.001) and larger fat cells (0.90 plusminus 0.26 vs. 0.78 plusminus 0.17 mum; p = 0.04) as compared with obese control subjects. Three genes (SREBP1c, p < 0.01; STAT5A, p = 0.02; and PPARitalic gamma2, p = 0.02) had significantly lower expression in obese type 2 diabetics, whereas C/EBPbeta only tended to be lower (p = 0.07).

Discussion: This cross-sectional study supports the hypothesis that impaired expression of adipogenic genes may result in impaired adipogenesis, potentially leading to larger fat cells in subcutaneous adipose tissue and insulin resistance.

Redesign of a multimedia course to reflect process not product

Universities are moving towards an environment of online teaching and learning. This is impacting the revision of degree programmes. A multimedia design course was revised to reflect and improve the design process inherent within multimedia production. The course was analyzed and revised using a critical reflection process. The outcome of the evaluation indicated that students were more satisfied but they had not grasped some of the fundamental concepts of design, and further revision of the course was needed for delivering materials and teaching in an online environment. The recommendation from the teaching team was to explore the range of research methods to formally revise the course again for future improvements to teaching practice and effective learning.

From online enhanced to wholly online: reflections on e-learning developments in teaching psychology

Deakin University has determined that every undergraduate student enrolled from 2004 will undertake at least one unit wholly online, without the usual face to face teaching that is a major component in on campus study. In response to this policy, Research methods in psychology has been developed as a wholly online unit and offered in 2004 as one of the first wholly online units to be run in the University. The design of the unit builds on the development and use of digital media and online technologies in teaching first and second year units. This paper outlines the antecedents of the unit’s design and operation, along with its current wholly online teaching and learning environment. The relationship between the use of digital resources and online features is mapped against key concepts and skills to be mastered in the unit. Distinctive student attributes to be developed in relation to the subject being offered wholly online are considered. The move to new e-learning territories of wholly online environments raises important research questions. An approach to researching wholly online teaching and learning environments in the discipline of psychology is detailed as a response to illuminating key dimensions of a significant development in e-learning in higher education.

Creative arts practice, creative industries : method and process as cultural capital

The value of artistic research is related not only to the products of creative arts practices, but also to methodological, material and social processes through which they operate.

This paper argues that although creative arts research methods – the use of personally situated, interdisciplinary and emergent approaches – contradict what is usually expected of research, such approaches underpin the innovative capacity of studio enquiry and its implication for extending practice-led research pedagogy across all research disciplines.

Associations between the home food environment and obesity-promoting eating behaviors in adolescence

Objective: This study examines relationships between multiple aspects of the home food environment and obesity-promoting characteristics of 12- to 13-year-old adolescents' diets, specifically frequency of consumption of high-energy fluids, sweet snacks, savory snacks, and take-out foods.

Research Methods: This was a cross-sectional study including 347 adolescents 12 to 13 years of age and their parents. Data were collected via self-completed surveys. The adolescents' diets were assessed using a Food Frequency Questionnaire derived from existing age-appropriate National Nutrition Survey data. An extensive range of domains within the home food environment were assessed. Bivariate linear regression analyses were run split by gender. Forced entry multiple linear regression analyses (adjusting for all variables significant in bivariate analyses as well as for maternal education) were also performed, stratified by the sex of the child.

Results: The influence of mothers, either as models for eating behaviors or as the providers of food, was pervasive. Mothers' intake of high-energy fluids (p = 0.003), sweet snacks (p = 0.010), savory snacks (p = 0.008), and take-out food (p = 0.007) was positively associated with boys' intake of all these foods. In addition, mothers' intake of high-energy fluids was positively associated with daughters' consumption of these drinks (p = 0.025). Furthermore, availability of unhealthy foods at home was positively associated with girls' sweet snack (p = 0.001), girls' savory snack (p < 0.001), boys' savory snack (p = 0.002), and, in the bivariate analyses, girls' high-energy fluid consumption (p = 0.002).

Discussion: This study of home food environment influences on adolescent diet highlights the pervasive influence of mothers in determining adolescents' obesity-promoting eating, providing direction for obesity prevention strategies and future research.

Leptin stimulation of COXIV is impaired in obese skeletal muscle myotubes

Objective
To investigate the effects of leptin on the mRNA abundance of key genes involved in fatty acid oxidation and mitochondrial biogenesis in cultured skeletal muscle myotubes derived from lean and obese individuals.

Research methods and procedures
Rectus abdominus muscle biopsies were obtained from surgical patients to establish primary skeletal muscle cell cultures. Two distinct primary cell culture groups were established (Lean and Obese) n = 7 in each group. Differentiated cultures were then exposed to leptin (2.5 μg/ml) for 6 h. mRNA expression was subsequently measured by real-time PCR analysis.

Results
Basal mRNA expression of βHAD, COXIII, COXIV, PGC-1α and SOCS3 in the cultured human skeletal muscle myotubes were similar, however, PDK4 mRNA was elevated (P < 0.05) in the myotubes derived from obese individuals. The addition of leptin resulted in a 2.5-fold increase in COXIV mRNA expression in the myotubes derived from Lean individuals only (P < 0.05). There was also a tendency for leptin to increase COXIII, βHAD and PDK4 mRNA expression in this same group. Leptin had no impact on the gene expression of all measured transcripts in myotubes derived from obese individuals.

Conclusion
Short-term exposure of human skeletal muscle myotubes to leptin stimulated the expression of the mitochondrial enzyme COXIV in myotubes derived from lean individuals, an effect that was abrogated in myotubes derived from obese individuals. These data demonstrate a novel capacity for leptin to increase mitochondrial biogenesis and thus, a possible increased capacity for lipid oxidation and the persistence of a defect in leptin signalling in human myotubes cultured from obese individuals.
