Obesity prevention programs demand high-quality evaluations

Obesity prevention programs are at last underway or being planned in Australia and New Zealand. However, it is imperative that they are well-evaluated so that they can contribute to continuous program improvement and add much-needed evidence to the international literature on what works and does not work to prevent obesity. Three critical components of program evaluation are especially at risk when the funding comes from service delivery rather than research sources. These are: the need for comparison groups; the need for measured height and weight; and the need for sufficient process and context information. There is an important opportunity to build collaborative mechanisms across community-based obesity prevention sites to enhance the program and evaluation quality and to accelerate knowledge translation into practice and policy.

On the pathogenicity of culture : questioning the rationality of "development" programs for perpetually dysfunctional aboriginal groups

All Australian Aborigines have experienced the impact of Western culture to some extent which has resulted in the traditional cultures being irrevocably decimated. The reaction to the disintegration of traditional culture has been marked by a variety of outcomes. While some Aborigines have either accepted or reached a level of accommodation to the new order, others have responded in maladaptive ways. For some Aborigines, the disintegration of traditional culture and society has generated conflict, confusion and the disintegration of personality, which is conducive to the evolution of a dysfunctional group. It is the circumstances of and policy responses to dysfunctional Aboriginal groups, therefore, that is the concern of this article.

Increasing access to mathematical thinking

This article is a contribution to understanding of teacher actions that can contribute to a successful mathematics learning experience, defined as one that engages all students, especially those who may sometimes feel alienated from mathematics and schooling, in productive and successful mathematical thinking and learning. We offer an example of a task that can form the basis of such a learning experience. The key elements are that the task is open-ended, that the teacher offers specific pedagogical prompts to support student leaning, that the teacher builds a sense of community by ensuring that there are some common experiences, and the teacher prepare prompts that can be used to support students who are experiencing difficulty, or to extend those students who complete the
basic task readily.

Children's mathematical thinking in different classroom cultures

The relationship between normative patterns of social interaction and children's mathematical thinking was investigated in 5 classes (4 reform and 1 conventional) of 7- to 8-year-olds. In earlier studies, lessons from these classes had been analyzed for the nature of interaction broadly defined; the results indicated the existence of 4 types of classroom cultures (conventional textbook, conventional problem solving, strategy reporting, and inquiry/argument). In the current study, 42 lessons from this data resource were analyzed for children's mathematical thinking as verbalized in class discussions and for interaction patterns. These analyses were then combined to explore the relationship between interaction types and  expressed mathematical thinking. The results suggest that increased complexity in children's expressed mathematical thinking was closely related to the types of interaction patterns that differentiated class discussions among the 4 classroom cultures.

Print versus website physical activity programs: a randomized trial.

Background: Mediated physical activity interventions can reach large numbers of people at low cost. Programs delivered through the mail that target the stage of motivational readiness have been shown to increase activity. Communication technology (websites and e-mail) might provide a means for delivering similar programs. Methods: Randomized trial conducted between August and October 2001. Participants included staff at an Australian university (n=655; mean AGE=43, standard deviation, 10 years). Participants were randomized to either an 8-week, stage-targeted print program (Print) or 8-week, stage-targeted website (Web) program. The main outcome was change in self-reported physical activity. Results: There was no significant increase in total reported physical activity within or between groups when analyzed by intention to treat (F [1,653]=0.41, p=0.52). There was a significant increase in total physical activity reported by the Print participants who were inactive at baseline (t [1,173]=−2.21, p=0.04), and a significant decrease in the average time spent sitting on a weekday in the Web group (t [1,326]=2.2, p=0.03). Conclusions: There were no differences between the Print and Web program effects on reported physical activity. The Print group demonstrated slightly larger effects and a higher level of recognition of program materials.

Smoking cessation programs in pregnancy: systematically addressing development, implementation, women's concerns and effectiveness

Objectives:  To increase a review's relevance to practitioners and service users and identify the implications for systematic review methodology. Methods:  A systematic review of the effects of smoking cessation programmes implemented during pregnancy integrated process indicators and the views of maternity service users and health promotion specialists. Additional qualitative data were extracted systematically from included randomised control trials (RCTs) to determine whether the design of interventions and conclusions arising from their evaluation related to the views of service users. On completing the review we reflected on the types of observational and qualitative research it drew on, where this research was incorporated into the review, and its added value. Results:   Incorporating process indicators into the review revealed: 1) problems with implementation and transplantation of some interventions and 2) studies with more stringent quality criteria and process evaluations demonstrated greater impact (weighted mean difference in smoking). Pregnant smokers were rarely involved in the design or evaluation of the interventions. Prior observational and qualitative studies and small scale consultations influenced the criteria by which the effectiveness of the interventions were judged, and revealed to what extent these criteria are adopted in practice.
Conclusions:   Systematically abstracting data about the development and delivery of interventions revealed gaps that might be filled by the active involvement of service users.

Questioning the assumptions of management paradigms : Aboriginal development programs in Australia

All Australian Aborigines have experienced the impact of Western culture to some extent, which has resulted in the traditional cultures being irrevocably decimated. The reaction to the disintegration of traditional culture has been marked by a variety of outcomes. While some Aborigines have either accepted or reached a level of accommodation to the new order, others have responded in maladaptive ways. For some Aborigines, the disintegration of traditional culture and society has generated conflict, confusion and the disintegration of personality, which is conducive to the evolution of a dysfunctional group. It is the circumstances of, and policy responses to, dysfunctional Aboriginal groups, therefore, that are the concern of this paper.

Approaches to the development and maintenance of professional values, ethics and attitudes in accounting education programs

IES 4, Professional Values, Ethics and Attitudes prescribes the professional values, ethics and attitudes professional accountants should acquire during the education program leading to membership of an IFAC member body.
The purpose of this paper is to support the development of IEPS 4.1, Approaches to Developing and Maintaining Professional Values, Ethics and Attitudes. This will assist and support IFAC member bodies to discharge effectively their responsibilities to ensure that candidates for membership of an IFAC member body are equipped with the appropriate professional values, ethics and attitudes to function as professional accountants.
The IAESB believes that this paper, and the findings of the independent research team, will be of interest and benefit to IFAC member bodies, accounting educators, and others seeking to implement ethics education programs for professional accountants.
