People, places and public health : evaluating the benefits of civic environmentalism in an urban local government context

Recent political, economic and social trends pose threats to the sustainability both of ecosystems and of human health. Australia’s environmental management record is poor, and while by international standards Australians enjoy good health, this is variable (AIHW, 2000). Within developed nations, heart disease, depression, alcohol dependence and stroke are major health issues (Mathers et al. 2002). In Australia, mental disorder is the number one contributor to the disease burden (Vos & Mathers 2000). Recent research has highlighted the role of social capital as a key determinant of health (Kawachi et al., 1997). Despite this, Putnam (1995) observes that social connectedness and civic engagement are in decline. People have less time for leisure and for volunteering, as many juggle paid work and caring for children. Anecdotal evidence suggests that engagement in civic environmentalism has human health benefits, relating to a combination of exposure to natural environments and increased social capital (Maller, Brown, Townsend & St. Leger, 2002). This link is supported by Furnass (1996) who defines well-being as including: satisfactory human relationships, meaningful occupation, opportunities for contact with nature, creative expression, and making a positive contribution to human society. Research conducted by Deakin University confirms the efficacy of linking people and places through civic environmentalism for addressing both ecosystem sustainability and human health and wellbeing. The research has included a pilot study to explore the human health benefits of membership of a local parkland ‘Friends’ group, and a more detailed follow-up study. The aims of the pilot study included:- To identify the range of motivations for joining the Friends group;- To document members’ perceptions of the benefits gained from membership of the group;- To assess the potential for Friends groups to be used as an ‘upstream’ health promotion measure.Face-to-face interviews were conducted with eleven members of a ‘Friends’ group in the eastern suburbs of Melbourne. Data was analysed thematically and key findings included:- Motivations: environmental; social; and pragmatic.- General benefits: community belonging; personal satisfaction; learning opportunities; physical activity; and better environment.- Health benefits: physical health; mental health; and social support. There was unanimous support for the use of ‘Friends’ groups as a tool for health promotion.The follow-up study, in the western suburbs of Melbourne, expanded on the pilot study by measuring the group’s social capital and by collecting self-report data on levels of health service usage. Data was collected through face-to-face interviews and a questionnaire. The findings were similar to the pilot study in relation to the motivations, benefits and the health promotion potential of such groups. However, health service usage data highlighted an apparent anomaly: while respondents perceived significant health benefits, some were nevertheless utilising health services at a relatively high level. This poses some questions requiring further exploration: Is this due to the poorer baseline health of the high health service usage members compared with their fellow members? Does involvement in the group offer health benefits that enable people who would otherwise be too unhealthy to participate in community groups to continue such involvement?If this is the case, then we may do well to look to locally-based mechanisms for promoting ecological sustainability as a tool also for promoting human health. Instead of prescribing a pill, connecting people and places through engagement with a local friends group may address our health problems at the same time as addressing local environmental problems.

Examining the living with possums policy in Victoria, Australia : community knowledge, support and compliance

Studying the human dimensions of wildlife management issues is now considered to be an essential component
of wildlife research. This study examined the Living with Possums policy in Victoria, Australia, in terms of the policy’s
success in educating the community and ensuring community compliance. Postal surveys and telephone interviews
were conducted across three samples from Greater Melbourne. These samples included people who had experiences
with possums on their property (n = 340), veterinary clinics (n = 45) and the general public (n = 103). Significant
levels of non-compliance were uncovered, highlighting the need for a renewed public education campaign to take place
along with a continued interest in this issue from government agencies and councils. The study also revealed
discrepancies between the policy and public preferences for possum management, suggesting that a shift in the
recommended management technique may be warranted.

Market makers v's the general public : a first look at S & P500 futures trade data

This paper considers 15 minute records of trading volume and traded prices coinciding with the reporting intervals required by the Commodity Futures Trading Commission. Records are extracted from trade records for market trade and also two way trade between market makers (CT1) and the general public (CT4) from January 1994 to June 2004. Futures price records are matched with S&P500 cash index price records. Simultaneous volatility models are specified and estimated to test trading volume to futures volatility lead/lag effects and also futures volatility to cash index volatility lead/lag effects. As we disaggregate from the market records to CT1 and CT4 records and further into year to year samples volume to futures volatility leading effects and also futures volatility to cash volatility leading effects dominate. The results raise important issues for risk management and dynamic hedging models employing intra-day trader data. A number of important issues for further analysis are also raised in this paper.

Building research capacity in General Practice : Incorporating research as a component of GP vocational training

Aims & rationale/Objectives : Australian research shows that most GP registrar supervisors lack confidence to support registrar research projects and themselves have little or no research experience. Assisting registrars to develop critical thinking skills and an understanding of research methods sufficient to enable active use of these tools in general practice is one of the curriculum statements in the RACGP Training Program Curriculum. A University Department of Rural Health (UDRH) and a General Practice Education and Training (GPET) organisation formed a partnership to: Engage basic term registrars in group research and concurrent research skills training program; Improve research skills, confidence, and knowledge; and Contribute research findings relevant to general practice.

Methods : Registrars' initial research knowledge and confidence was measured by a questionnaire. In addition to a final focus group, feedback via evaluation forms was sought from the 11 registrars and two GPET supervisors at the conclusion of each research training session.

Principal findings : Approaches

Implications : Research skills development training and involvement in research can be successfully integrated into a GP vocational training program.

Television viewing habits and time use in Australian preschool children : an exploratory study

The overall aim in this study was to investigate time use in Australian preschool children, paying close attention to the types of television programs and videos/DVDs they watch. Ninety-two mothers of preschool children completed five activity diaries, for three typical weekdays and two weekend days. On average, children spent around just over 1 hour per weekday watching television and 30 minutes watching videos/DVDs; on weekends they spent on average 1 hour watching television and the same amount of time watching videos/DVDs. On weekdays, children spent more time watching child informative television; on the weekend they spent more time watching child animated television programs. When not watching television, children were mainly engaged in general play or in outdoor play. Child informative television was associated positively with time spent outdoors and in general and pretend play on weekdays (and for general play also on weekend days), whereas overall television viewing was correlated negatively with reading. Our findings suggest that the content of television programs may play a critical role in the relationship between television and other daily activities.

Dispersion of information or market behaviour : general public trading in S & P 500 index futures

This paper considers 15 minute records of trading volume and traded prices coinciding with the reporting intervals required by the Commodity Futures Trading Commission. Records are extracted from trade records for two way trade between market makers (CTI1) and the general public (CTI4) from January 1994 to June 2004. Futures price records are matched with S&P500 cash index price records. Simultaneous volatility models are specified and estimated to test trading volume to futures volatility lead/lag effects and also futures volatility to cash index volatility lead/lag effects. There is evidence that existing theoretical models of the general public trading behaviour do not explain such behaviour in these very actively traded markets. These effects can depend more on market conditions than what is suggested in theoretical models.

Meteorological influences on coastal sea levels west of Port Phillip and their engineering significance

This report presents the results of an analysis of three years of tide and meteorological data aimed at delineating the influences of atmospheric pressure, waves, onshore winds and longshore winds on coastal sea levels West of Port Phillip Bay, Victoria« The data was used to develop predictive and hindcasting techniques for meteorological tides on the Otway Coast, using statistical methods, an empirical method and a mathematical model. The nature and magnitude of contributions of the various components of the meteorological tide, and the general variability of monthly and seasonal variations were also studied. It was found that meteorological tides on the Otway Coast can account for significant sea level changes, with the main factors being wind and atmospheric pressure. The wind component of the meteorological tide was found to be approximately twice the pressure component, and longshore winds were found to be more significant than onshore winds for wind setup on the Otway Coast. The meteorological tide models developed enable estimates of wind setup and atmospheric pressure setup on the Otway Coast to be readily computed using data from synoptic charts. The wave setup component could not be separated from the meteorological tide and is included in the wind setup component. The results of the investigation are relevant to the design and maintenance of coastal engineering works, and point to the need for the establishment and operation of coastal management schemes on the Otway Coast.

Organizational discourse and change : positions, perspectives, progress and prospects

It has been 10 years since The Journal of Applied Behavioral Science (JABS) published a special issue titled “Discourses of Organizing” (Vol. 36, No. 2, 2000) based on the then emerging field of organizational discourse. A decade on seems to be an appropriate juncture at which to reflect on the range of work produced and the general progress made and consider possible future directions. In addition to briefly taking stock of developments within the field, this opening piece provides an opportunity to introduce the subsequent articles contained in this special issue and locate them within the developing landscape of discursive contributions on organizational change. Given these broad aims, there are three main sections in this introductory article. First, the general trajectory and shifting patterns of “organizational discourse and change” contributions are considered and a way of thinking about different waves of engagement is presented. Then, in the second main section, the focus and general contribution of the articles presented in this collection are discussed. Finally, we conclude by speculating on emerging trends and the scope for further inquiry.

Identification of depression in diabetes the efficacy of PHQ-9 and HADS-D

Background
Clinical guidelines advise screening for depression in patients with diabetes. The Patient Health Questionnaire (PHQ-9) and the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D) are commonly used in primary care.

Aim
To compare the efficacy of HADS-D and PHQ-9 in identifying moderate to severe depression among primary care patients with type 2 diabetes.

Design of study
Self-report postal survey, clinical records assessed by GPs.

Setting
Seven metropolitan and rural general practices in Victoria, Australia.

Method
Postal questionnaires were sent to all patients with diabetes on the registers of seven practices in Victoria. A total of 561 completed postal questionnaires were returned, giving a response rate 47%. Surveys included demographic information, and history of diabetes and depression. Participants completed both the PHQ-9 and HADS-D. Clinical data from patient records included glycosylated hemoglobin (HbA1c) levels and medications.

Results
The proportion of the total sample completing HADS-D was 96.8% compared with 82.4% for PHQ-9. Level of education was unrelated to responses on the HADS-D but was related to completion of the PHQ-9. Using complete data (n = 456) from both measures, 40 responders showed HADS-D scores in the moderate to severe range, compared with 103 cases identified by PHQ-9. Only 35 cases were classified in the moderate to severe category by both the PHQ-9 and HADS-D. Items with the highest proportions of positive responses on the PHQ-9 were related to tiredness and sleeping problems and, on the HADS-D, feeling slowed down.

Conclusion
It may be that the items contributing to the higher prevalence of moderate to severe depression using the PHQ-9 are due to diabetes-related symptoms or sleep disorders.

Fish oil replacement in starter, grow-out, and finishing feeds for farmed aquatic animals

As aquaculture production continues to grow, there will be an increased use of lipid resources (oils and fats) alternative to fish oil for feed production. The potential for the use of these alternatives varies depending on the feeds in which they are included according to the production phase of the animals to which they are being fed. In starter feeds, where rapid growth, high survival, and normal development are critical priorities, there will remain a need for the use of lipid resources high in omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA). Fish in this starter phase have a critical requirement for the n-3 LC-PUFA docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), and fish oils remain the only cost-effective source of these nutrients in the volumes required. However, the greatest demand for lipids is in those diets for the grow-out phase. Most studies on alternative lipid use with animals in this part of the production phase show positive outcomes, in that there are few studies where all the added fish oil cannot be replaced. There are some species, however, where potential replacement levels are suggested to be more conservative, and a general substitution level in this production phase of 75% has been suggested. One of the key effects noted across the grow-out phase is that all alternatives affect the flesh fatty acid characteristics by reducing the level of n-3 LC-PUFA. This issue has provoked the concept of finisher diets, whereby a high n-3 LC-PUFA content diet is fed in order to restore the desired meat fatty acid profiles. Studies examining this concept have found that the tissue triacylglycerol fatty acids were greatly modified and responded in a simple dilution process to the added oil fatty acid composition, whereas the fatty acids of tissue phospholipids were less influenced by dietary fatty acid makeup.

Evidence-based development of school-based and family-involved prevention of overweight across Europe : the ENERGY-project's design and conceptual framework

Background
There is an urgent need for more carefully developed public health measures in order to curb the obesity epidemic among youth. The overall aim of the "EuropeaN Energy balance Research to prevent excessive weight Gain among Youth" (ENERGY)-project is the development and formative evaluation of a theory-informed and evidence-based multi-component school-based and family-involved intervention program ready to be implemented and evaluated for effectiveness across Europe. This program aims at promoting the adoption or continuation of health behaviors that contribute to a healthy energy balance among school-aged children. Earlier studies have indicated that school and family environments are key determinants of energy-balance behaviors in schoolchildren. Schools are an important setting for health promotion in this age group, but school-based interventions mostly fail to target and involve the family environment.

Methods
Led by a multidisciplinary team of researchers from eleven European countries and supported by a team of Australian experts, the ENERGY-project is informed by the Environmental Research Framework for Weight gain Prevention, and comprises a comprehensive epidemiological analysis including 1) systematic reviews of the literature, 2) secondary analyses of existing data, 3) focus group research, and 4) a cross European school-based survey.

Results and discussion
The theoretical framework and the epidemiological analysis will subsequently inform stepwise intervention development targeting the most relevant energy balance-related behaviors and their personal, family-environmental and school-environmental determinants applying the Intervention Mapping protocol. The intervention scheme will undergo formative and pilot evaluation in five countries. The results of ENERGY will be disseminated among key stakeholders including researchers, policy makers and the general population.

Conclusions
The ENERGY-project is an international, multidisciplinary effort to develop and test an evidence-based and theory-informed intervention program for obesity prevention among school-aged children.

Prevalence of mood and anxiety disorder in self reported irritable bowel syndrome (IBS). An epidemiological population based study of women

Background Irritable bowel syndrome (IBS) is commonly regarded as a functional disorder, and is hypothesized to be associated with anxiety and depression. This evidence mainly rests on population-based studies utilising self-report screening instruments for psychopathology. Other studies applying structured clinical interviews are generally based on small clinical samples, which are vulnerable to biases. The extant evidence base for an association between IBS and psychopathology is hence not conclusive. The aim of this study was therefore to re-examine the hypothesis using population-based data and psychiatric morbidity established with a structured clinical interview.

Methods Data were derived from a population-based epidemiological study (n = 1077). Anxiety and mood disorders were established using the Structured Clinical Interview for DSM-IV-TR (SCID-I/NP) and the General Health Questionnaire (GHQ-12). Current and lifetime IBS was self-reported. Hypertension and diabetes were employed as comparison groups as they are expected to be unrelated to mental health.

Results Current IBS (n = 69, 6.4%) was associated with an increased likelihood of current mood and/or anxiety disorders (OR = 2.62, 95%CI 1.49 - 4.60). Half the population reporting a lifetime IBS diagnosis also had a lifetime mood or anxiety disorder. Exploratory analyses demonstrated an increased prevalence of IBS across most common anxiety and mood disorders, the exception being bipolar disorder. The association with IBS and symptoms load (GHQ-12) followed a curved dose response pattern. In contrast, hypertension and diabetes were consistently unrelated to psychiatric morbidity.

Conclusions IBS is significantly associated with anxiety and mood disorders. This study provides indicative evidence for IBS as a disorder with a psychosomatic aspect.

Indigenous communities and new media : questions on the global digital age

Purpose – The purpose of this paper is to look at some of the issues surrounding access to and the use of new media technologies, and questions why this is an area of study that receives a marginal focus in academic work.
Design/methodology/approach – Drawing on previous literature in the area of information and communications technology (ICT) adoption and social exclusion, this paper combines the methodological frameworks adopted by hegemony research and more general studies of new media.
Findings – The paper discusses the impacts of new media use by Indigenous communities, within the framework of discussions about a “global Digital Age”. The paper also briefly looks at the social
implications of new media adoption.
Originality/Value - It questions the assumption that adoption and use of new media is for the "good" or "benefit" of all. It will be of value to researchers of ICT adoption by Indigenous communities.

Critical policy sociology : historiography, archaeology and genealogy as methods of policy analysis

In recent times critical approaches to educational policy studies have been subject to increasing interrogation over methodological issues, often by critical policy researchers themselves. In the main, their reflexive posturings have been informed by critique which proceeds that beyond brief descriptions of research logis tics and a general commitment to the methodologies of a critical orientation, critical policy analyses offer few explicit accounts of the connections between the stories they tell about policy and the data used to tell them. As a way of addressing these silences, this paper proposes three methodological approaches within which to explore and explain matters of policy, each generating its own particular view of the (policy) issues worth looking for, where they can be found and how to look for them. Drawing on research into the production of Australian higher education policy during the late 1980s and early 1990s, the paper illustrates the characteristics of these approaches, referring to them as policy historiography, policy genealogy and policy archaeology. Without claiming absolute distinctions between their interests, the paper couples policy historiography with the substantive issues of policy at particular hegemonic moments, policy genealogy with social actors' engagement with policy, and policy archaeology with conditions that regulate policy formations.
