Behavior and weight correlates of weight-control efforts in Australian women living in disadvantage : the READI study

Background
With increasing obesity rates worldwide, more and more people are actively attempting to lose weight or avoid weight gain, but relatively little is known about what specific behaviors comprise these efforts and which, if any, are associated with better weight control over time.

Methods
This paper reports relationships between body weight, weight-control efforts and related behaviors over a three-year period in 1,634 Australian women. The women were purposefully recruited from 80 disadvantaged neighborhoods in Victoria, Australia. Weight loss efforts were categorized as trying to lose weight, trying to prevent weight gain and no weight-control efforts. Behavioral correlates examined included different kinds of physical activity and consumption of a number of specific foods types.

Results and discussion
Self-reported body weight at baseline was higher in women trying to lose weight. Frequency of consumption of low energy density foods was positively associated with reported weight-control efforts, as was frequency of reported total and leisure-time physical activity. Longitudinal associations between changes in weight-control efforts and changes in behaviors were consistent with the cross-sectional findings. At three-year follow up, however, weight-control efforts were not associated with change in body weight. More detailed analyses of specific food choices suggested that part of the explanation of no effect of reported weight-control efforts and weight over time might be that people are not as well-informed as they should be about the energy density of some common foods. In particular, those reporting engagement in weight-control efforts reported reducing consumption of carbohydrate-containing foods such as bread and potatoes more than is justified by their energy content, while they reported increasing consumption of some high energy density foods (e.g., cheese and nuts).

Conclusion
It is tentatively concluded that women living in disadvantaged neighborhoods understand messages about weight-control (more activity and foods with lower fat and lower energy density) but that some foods eaten more by women engaged in weight control may reduce the effectiveness of these efforts.

Malware variant detection using similarity search over sets of control flow graphs

Static detection of polymorphic malware variants plays an important role to improve system security. Control flow has shown to be an effective characteristic that represents polymorphic malware instances. In our research, we propose a similarity search of malware using novel distance metrics of malware signatures. We describe a malware signature by the set of control flow graphs the malware contains. We propose two approaches and use the first to perform pre-filtering. Firstly, we use a distance metric based on the distance between feature vectors. The feature vector is a decomposition of the set of graphs into either fixed size k-sub graphs, or q-gram strings of the high-level source after decompilation. We also propose a more effective but less computationally efficient distance metric based on the minimum matching distance. The minimum matching distance uses the string edit distances between programs' decompiled flow graphs, and the linear sum assignment problem to construct a minimum sum weight matching between two sets of graphs. We implement the distance metrics in a complete malware variant detection system. The evaluation shows that our approach is highly effective in terms of a limited false positive rate and our system detects more malware variants when compared to the detection rates of other algorithms.

A conceptual classification of parents’ attributions of the role of food advertising in children’s diets

Background : High levels of child obesity are triggering growing concerns about the prevalence and effects of food advertising targeted at children. Efforts to address this advertising are confounded by the expanding repertoire of media and promotional techniques used to reach and attract children. The present study explored parents’ views on food marketing and the strategies parents employ when attempting to ameliorate its effects. As part of an online survey of Australian parents’ attitudes towards a range of food advertisements, respondents were invited to provide additional comment in an open-ended question. The question was optional and asked “Are there any other comments you would like to make?”. One in five of the survey respondents (18%; n = 235) elected to answer this question by discussing their views on food advertising and children’s diets. The responses were imported into NVivo10 for coding and analysis. A grounded approach was used to draw meaning from the data and develop a proposed conceptual classification of parents’ attributions relating to food advertising and its consequences.

Results : The majority of responses related to the negative perceived effects of unhealthy food advertising on children’s diets, with few respondents considering such advertisements to be innocuous. The responses were classified into four conceptual categories reflecting differing attitudes to advertising (negative to neutral) and varying levels of locus of control (low to high). The typical characteristics of parents allocated to the four categories exhibited variation according to weight status, television viewing habits, education level, and family size. The largest number of responses was coded to the category characterized by a negative attitude toward food advertising and a low locus of control. Parents in this category were more likely than others to be overweight/obese and heavy television viewers. Parents in the negative attitude to advertising and high locus of control category nominated a variety of parenting practices that could form the basis of parent education interventions.

Conclusions : The results suggest that many Australian parents may feel disempowered in the face of high levels of advertising for unhealthy foods. The current voluntary regulatory code appears to be inadequate in scope and coverage to address this situation.

Loyalty to the profession? A study of Australian financial planners

The purpose of this paper is to examine the demographic variables of age and gender in conjunction with three independent variables: Internal versus external locus of control personality dimension, individualist versus collectivist personality dimension, and perceived environmental uncertainty and to relate same to the professional commitment (PC) of financial planners in Australia. A questionnaire was used to survey a sample of 312 financial planners nationally, with a 36% response rate and statistically significant results. At the 90% confidence level (p=0.10) respondents over the age of 35 demonstrated no difference between their levels of professional commitment than did those under the age of 35, while at the same level of confidence, females demonstrated a statistically significant higher level of PC than did their male counterparts. Respondents with an external locus of control displayed lower levels of PC (p=0.10) that those with an internal locus of control. These findings contribute to our understanding of the professional commitment of financial planners, and are important from a public policy perspective in an era of increasing attention to, and likely increased regulation of, the financial planning industry.

Professional commitment of financial planners in Australia: an examination

The purpose of this paper is to examine the demographic variables of age and gender in conjunction with three independent variables: Internal versus external locus of control personality dimension, individualist versus collectivist personality dimension, and perceived environmental uncertainty and to relate same to the professional commitment (PC) of financial planners in Australia. A questionnaire was used to survey a sample of 312 financial planners nationally, with a 36% response rate and statistically significant results. At the 95% confidence level (p=0.05) respondents over the age of 35 demonstrated no difference between their levels of professional commitment than did those under the age of 35, while at the same level of confidence, females demonstrated no statistically significant difference in their level of PC than did their male counterparts. Respondents with an external locus of control displayed lower levels of PC (p=0.05), than those with an internal locus of control but these were not statistically significant. These findings contribute to our understanding of the professional commitment of financial planners, and are important from a public policy perspective in an era of increasing attention to, and likely increased regulation of, the financial planning industry.

Financial planners in Australia : an examination of loyalty

The purpose of this paper is to determine whether the demographic variables of age, gender and length of service, and the levels of the three independent variables of internal versus external locus of control personality dimension, individualist versus collectivist personality dimension, and perceived environmental uncertainty can be shown to be related to the organisational commitment (OC) and professional commitment (PC) of financial planners in Australia. The financial planners employed by one major Australian bank, during the period November to December, 2004 were surveyed using an instrument derived from established questionnaires. It was mailed nationally to 312 financial planners. A response rate of 36% was achieved, equating to 113 useable responses. The analyses revealed no statistically significant results at the 95% confidence level (p=0.05), that the level of OC and PC for respondents over the age of 35 differed from those under the age of 35. At the same level of confidence, females demonstrated a statistically significant higher level of OC than did their male counterparts, however there was no difference between their levels of PC. Financial planners employed for a period of over 3 years showed no difference in their levels of OC or PC than those employed for a period of less than 3 years (p=0.05). Respondents with an external locus of control displayed  statistically significant lower levels of OC than those with an internal locus of control, however there was no difference between these groups in their levels of PC (p=0.05). Such findings contribute to our understanding of the organisational and professional commitment of financial planners, and have implications for employers in terms of hiring and retention of employees. The analyses are also important from a public policy perspective in an era of increasing attention to, and likely increased regulation of, the financial planning industry.

What criteria do police officers use to measure the success of an interview with a child?

This study used a mixed-methods approach to explore the perceptions of a heterogeneous sample of 75 police interviewers regarding their performance in a mock interview with a 5-7-year-old child. Each officer recruited for this study was authorised to conduct investigative interviews with children. Specifically, we explored how the officers' perception of what makes a good interview differs depending on their background experience and their (perceived and actual) ability to adhere to best-practice interview guidelines. Overall, the officers' perceptions of what constitutes an effective interview were not entirely consistent with those held by experts in forensic interviewing. The majority of the interviewers perceived that the locus of control in the interview rested primarily with the child and/or the environmental setting. In contrast, experts tend to place the central onus of responsibility for the outcome of an interview on the skill of the interviewer in using open-ended questions. Several possible explanations for, and the implications of, these findings are discussed.

Associations between family circumstance and weight status of Australian children

To examine associations between weight status and multiple indicators of family circumstance in Australian elementary school children. Data were combined from the 2001 Children's Leisure Activities Study (CLAS Study) and 2002/3 Health, Eating and Play Study (HEAP Study), involving 2520 children in Grades Prep (mean age 6 years) and 5-6 (mean age 11 years) in Melbourne, Australia. Children's body mass index (BMI) was calculated from measured height and weight. Weight status (non-overweight or overweight) was determined according to International Obesity Taskforce cut-off points and BMI was transformed to z-scores based on the 2000 US growth chart data. Parents reported family circumstance (number of parents in the home, marital status, presence of siblings, parental education, parental employment status, parental work hours [HEAP Study only]) and parental BMI. Regression analyses were conducted for the sample overall and separately for young girls, young boys, older girls and older boys. Children in single-parent homes, those without siblings, and those with less educated mothers and fathers tended to have higher z-BMIs (p=0.002, p=0.003, p<0.001 and p<0.001, respectively) and were more likely to be overweight (p=0.003, p<0.001, p<0.001 and p=0.02, respectively). Associations were stronger for older children. Parental employment and work hours were not consistently associated with child weight status. The multivariable models did not demonstrate a cumulative explanatory effect (R2=0.02), except when maternal BMI was included (R2=0.07). Individual measures of family circumstance were differentially associated with child weight status and appeared to be largely independent of other measures of family circumstance. Childhood overweight interventions may need to be tailored based on the age, gender, maternal BMI and family circumstances of the target group.

Professional identity and the contemporary university: a culture of control, accountability and virtuality?

In recent years many changes to the funding and management of universities have taken place. In the current climate of academia in Australia professional academics find themselves immersed in the culture of the managed university that uses the rhetoric of commitment to flexible delivery to put in place systems designed to increase accountability, surveillance and control. At the same time some argue that the focus on research, quality teaching and effective pedagogy has lessened. The empirical research base for this paper has enabled me to better understand some of the emerging trends my university. It looks at how changes to the experience of being academic impact on the work of academics as the power relations of the university continuously reposition them, and how academics in turn display resistance technologies. Changes to the technologies of management/administration of the university have resulted in what some academics have described as a loss of valuing of their knowledge and expertise and which may be seen by some as a threat to their opportunities to conduct productive educational inquiry.

The influence of locus of attribution, level of employee authority and employee concern on consumers postrecovery evaluations

This study employed a 3 x 2 x 2 full-factorial, between-subjects design experiment involving locus of attribution, concern, and the level of authority of the employee performing the recovery on consumers’ postcomplaint evaluations. The research, conducted in a restaurant context, involved a sample of 411 undergraduate students. Findings suggest that customers are less dissatisfied and more likely to revisit the restaurant when the location of the cause of the failure is internal (i.e., they are to blame). In addition, consumers are less likely to repurchase when the manager, as opposed to the waiter, is responsible for the service failure.

'Research as dialogue' and cross-cultural consultations : confronting relations of power

ln this paper, we discuss methodological issues that emerged as we worked through a small empirical research project, 'Engaging Aboriginal students in education through community empowerment'. Recent national policy statements (see, for example, MCEETYA 2000,. NBEET 1995) argue the importance of education/research that keeps the locus of control within the Aboriginal community as a means to further the goal of self-determination and improve educational outcomes. In keeping with these recommendations, our project aimed to challenge assimilationist frameworks and sought to 'empower' members of the local Aboriginal community through participation in the project. 'Research as dialogue' was a guiding principal and a primary aim was to listen actively to all key stakeholders in the remote community setting, particularly to lndigenous parents, students and teachers, in order to identify current strengths and concerns regarding the provision of culturally inclusive schooling. A proposed second stage of the project is to develop, on the basis of these consultations and in collaboration, community-based education projects that engage non-attending Aboriginal students. Here we discuss the consultative processes undertaken in stage one of the project, and critically analyse the difficulties as well as potential strengths of trying to form collaborative partnerships as researchers across cultural differences and with diverse community groups.
