Assessing sustainability : a technical fix or a means of social learning?

The contextual nature of sustainability makes it extremely difficult to measure. Across the world each region has a specific environment and history that has shaped values and perceptions of the local community. In response, a wide range of tools has been developed that employ differing techniques to measure sustainability. These have a range of applications from global to site-specific scales. However, it is yet to be resolved whether assessments made using these tools reflect a technical focus with no close links to the knowledge and perceptions of stakeholders, community and management decisions, or whether the assessments reflect the knowledge and perceptions of local stakeholders and the community. In the southwest region of Victoria, Australia, a sustainability index called AIRS (An Index of Regional Sustainability) has recently been developed. This tool is based on indicators selected by stakeholders and considers relationships between the indicators. The aim of this paper is to report an ex-post evaluation of the AIRS sustainability assessment conducted at a subcatchment scale. The evaluation assesses AIRS's ability to assess regional sustainability and compares and contrasts the subcatchment assessments with the knowledge and perceptions of stakeholders and the community. A participatory approach that acknowledges key stakeholders was used for the evaluation process. Representatives from four stakeholder groups were interviewed to elicit their views of the AIRS assessment, its relevance, quality, applicability and priorities for future development. Strengths and weaknesses of AIRS are revealed and its contribution to social learning is highlighted.

A hazardous substance exposure prevention rating method for intervention needs assessment and effectiveness evaluation: the small business exposure index

Aims This paper describes the refinement and adaptation to small business of a previously developed method for systematically prioritizing needs for intervention on hazardous substance exposures in manufacturing worksites, and evaluating intervention effectiveness. Methods We developed a checklist containing six unique sets of yes/no variables organized in a 2 × 3 matrix of exposure potential versus exposure protection at three levels corresponding to a simplified hierarchy of controls: materials, processes, and human interface. Each of the six sets of indicator variables was reduced to a high/moderate/low rating. Ratings from the matrix were then combined to generate an exposure prevention 'Small Business Exposure Index' (SBEI) Summary score for each area. Reflecting the hierarchy of controls, material factors were weighted highest, followed by process, and then human interface. The checklist administered by an industrial hygienist during walk-through inspection (N = 149 manufacturing processes/areas in 25 small to medium-sized manufacturing worksites). One area or process per manufacturing department was assessed and rated. A second hygienist independently assessed 36 areas to evaluate inter-rater reliability. Results The SBEI Summary scores indicated that exposures were well controlled in the majority of areas assessed (58% with rating of 1 or 2 on a 6-point scale), that there was some room for improvement in roughly one-third of areas (31% of areas rated 3 or 4), and that roughly 10% of the areas assessed were urgently in need of intervention (rated as 5 or 6). Inter-rater reliability of EP ratings was good to excellent (e.g., for SBEI Summary scores, weighted kappa = 0.73, 95% CI 0.52–0.93). Conclusion The SBEI exposure prevention rating method is suitable for use in small/medium enterprises, has good discriminatory power and reliability, offers an inexpensive method for intervention needs assessment and effectiveness evaluation, and complements quantitative exposure assessment with an upstream prevention focus.

A Cross-Cultural Evaluation of the Personal Wellbeing Index – School Children in Samples of Australian and Portuguese Adolescents

The practice of comparing nations on subjective wellbeing (SWB) is becoming commonplace, with many countries ranked by economists and social scientists alike according to average levels of SWB based on survey responses. Such large, multi-national population surveys have the potential to generate insights into the causes and correlates of SWB within different cultural groups, as well as inform policy regarding how to improve the wellbeing of citizens. At the heart of these large-scale research endeavors are SWB measures that function equivalently between the various participating cultural groups. For this reason, it is concerning that their remains a paucity of research that supports measurement equivalence for many SWB instruments commonly employed. Thus, it remains unclear whether variations in SWB across cultures reflect true differences, or whether these differences reflect measurement biases (e.g., response bias inherent within a particular cultural group). The aim of this study was to examine the psychometric equivalence of the Personal Wellbeing Index–School Children (PWI-SC) in convenience samples of Australian and Portuguese adolescents using multiple-group confirmatory factor analysis. Participants comprising the Australian sample were 1104 Victorian high-school students aged between 12 and 19 years (M = 14.42, SD = 1.63). Participants comprising the Portuguese sample were 573 high-school students living in Portugal aged between 12 and 18 years (M = 14.32, SD = 1.72). The results demonstrated strict factorial invariance between both versions of the PWI-SC, suggesting that this scale measures the same underlying construct in both samples. Moreover, these findings provide preliminary support for quantitative comparisons between Australian and Portuguese adolescents on the SWB variable as valid.

Accounting narrative evaluation: using texture as a measure of quality

This paper applies a texture-based approach to evaluating accounting narratives. We employ the texture index created by Sydserff and Weetman (1999) as it is purported to evaluate narratives more accurately than previous methods. Not enough emphasis has been placed on the utilisation of linguistic tools in the accounting context. We see that a rigorous test serves the accountability function and may contribute positively to investor protection and confidence. We support the contention that improving narrative evaluation will help increase the quality of accounting narratives as they are presented in corporate annual reports. Quality for purpose of this paper is defined as a function of readability and understandability. These characteristics are considered essential for informed investment decision-making. We focus on the usefulness of the texture index in determining an appropriate measure of both readability and understandability by applying the texture index to a sample of corporate annual reports. Our results show conditional support for the use of the texture index as a viable alternative to readability tests.

Evaluation of a brief pilot nutrition and exercise intervention for the prevention of weight gain in general practice patients

Objective To pilot-test a brief written prescription recommending lifestyle changes delivered by general practitioners (GPs) to their patients.

Design The Active Nutrition Script (ANS) included five nutrition messages and personalised exercise advice for a healthy lifestyle and/or the prevention of weight gain. GPs were asked to administer 10 scripts over 4 weeks to 10 adult patients with a body mass index (BMI) of between 23 and 30 kg m− 2. Information recorded on the script consisted of patients' weight, height, waist circumference, gender and date of birth, type and frequency of physical activity prescribed, and the selected nutrition messages. GPs also recorded reasons for administering the script. Interviews recorded GPs views on using the script.

Setting General practices located across greater Melbourne.

Subjects and results Nineteen GPs (63% female) provided a median of nine scripts over 4 weeks. Scripts were administered to 145 patients (mean age: 54 ± 13.2 years, mean BMI: 31.7 ± 6.3 kg m− 2; 57% female), 52% of whom were classified as obese (BMI >30 kg m− 2). GPs cited ‘weight reduction’ as a reason for writing the script for 78% of patients. All interviewed GPs (90%, n = 17) indicated that the messages were clear and simple to deliver.

Conclusions GPs found the ANS provided clear nutrition messages that were simple to deliver. However, GPs administered the script to obese patients for weight loss rather than to prevent weight gain among the target group. This has important implications for future health promotion interventions designed for general practice.

A methodology of health information security evaluation

With the conversion of paper health records to electronic health records, the health care sector is increasingly relying on technology to maintain the integrity of and update patients’ data. This reliance on technology requires an acute level of protection from technological disasters and/or threats of human error or sabotage. Research has shown there are inadequacies in the installation and use of security controls for health information records and that current methods of security analysis lack the techniques to analyse the technical and social aspects of security. This paper reports on progress towards development of a health information security evaluation methodology based on Unified Modelling Language techniques, and discusses an imminent case study that will be used for validation of the methodology.

Economic Evaluation of a Primary Care Trial to Reduce Weight Gain in Overweight/Obese Children: The LEAP Trial

Background:- A common policy response to the childhood obesity epidemic is to recommend that primary care physicians screen for and offer counseling to the overweight/obese. As the literature suggests, this approach may be ineffective; it is important to document the opportunity costs incurred by brief primary care obesity interventions that ultimately may not alter body mass index (BMI) trajectory.

Methods:- Live, Eat and Play (LEAP) was a randomized controlled trial of a brief secondary prevention intervention delivered by family physicians in 2002-2003 that targeted overweight/ mildly obese children aged 5 to 9 years. Primary care utilization was prospectively audited via medical records, and parents reported family resource use by written questionnaire. Outcome measures were BMI (primary) and parent-reported physical activity and dietary habits (secondary) in intervention compared with control children.

Results:- The cost of LEAP per intervention family was AU $4094 greater than for control families, mainly due to increased family resources devoted to child physical activity. Total health sector costs were AU $873 per intervention family and AU $64 per control, a difference of AU $809 {P < .001). At 15 months, intervention children did not differ significantly in adjusted BMI or daily physical activity scores compared with the control group, but dietary habits had improved.

Conclusions:- This brief intervention resulted in higher costs to families and the health care sector, which could have been devoted to other uses that do create benefits to health and/or family well-being. This has implications for countries such as the United States, the United Kingdom, and Australia, whose current guidelines recommend routine surveillance and counseling for high child BMI in the primary care sector.

Extruded products with Fenugreek (Trigonella foenum-graecium) chickpea and rice: Physical properties, sensory acceptability and glycaemic index

The present study investigated the effects of fenugreek flour (Trigonella foenum-graecum) and debittered fenugreek polysaccharide (FenuLife^®) inclusion on the physical and sensory quality characteristics, and glycaemic index (GI) of chickpea–rice based extruded products. Based on preliminary evaluation with different proportions of chick pea and rice, a blend of 70:30 chickpea and rice was chosen as the control for further studies. The control blend, replaced with fenugreek flour at 2%, 5% and 10%, or fenugreek polysaccharide at 5%, 10%, 15% and 20%, was extruded at the optimum processing conditions as specified in the detailed study. The extruded products were evaluated for their physical (moisture retention, expansion, hardness, water solubility index (WSI) and water absorption index (WAI)), sensory (flavor, texture, color and overall acceptability) characteristics and in vitro GI to evaluate their suitability as extruded snack products.

Due to the distinct bitter taste, inclusion of fenugreek flour was not acceptable at levels more than 2% in extruded chickpea based products. Addition of fenugreek polysaccharide resulted in slight reduction in radial expansion (P < 0.05), while longitudinal expansion increased. WAI increased while WSI decreased compared to the control (P < 0.05). The mean scores of sensory evaluation indicated that all products containing fenugreek polysaccharide up to 15% were within the acceptable range. There were no significant differences (P > 0.05) between products containing 5–15% fenugreek polysaccharide in their color, flavor, texture and overall quality.

Fenugreek, in the form of debittered polysaccharide (FenuLife^®) could be incorporated up to a level of 15% in a chickpea–rice blend to develop snack products of acceptable physical and sensory properties with low GI Index.

Nutrition screening in long-term care facilities : an evaluation of the methodological quality of available instruments

A variety of nutrition screening instruments have been developed and implemented for identifying the risk of undernutrition among community and hospitalized older adults. Despite the high prevalence of undernutrition amongst older adults in long-term care, few screening instruments have been developed or evaluated in this setting. This review aims to evaluate the validity, reproducibility and feasibility of nutrition screening instruments developed for use, or described as being used, with older adults in long-term care. Ten publications encompassing nine independent nutrition screening tools were identified using electronic databases and manual searches of reference lists. The Mini Nutritional Assessment-Short Form (MNA-SF) was the most widely evaluated nutrition screening instrument and met the requirements for a valid instrument (sensitivity and specificity >0.9) for use in the long-term care setting. Modified versions of the MNA for use in China and South Africa also demonstrated acceptable levels of sensitivity and specificity. Other nutrition screening instruments were found to have variable levels of sensitivity and specificity and while some demonstrated levels consistent with the MNA-SF, only two were evaluated across more than one study population, Body Mass Index (BMI)+weight loss and BMI+albumin. These same instruments reported the highest levels of inter-rater and test-retest reproducibility, although this was only tested in one other instrument (Chinese Nutrition Screen -modified MNA). In conclusion, it is evident from this review that further work in this area is needed. Based on validity, reproducibility and feasibility it appears that BMI+weight loss is the most suitable nutrition screening instrument for use in the long-term care setting at this time. MNA-SF is promising; however, there is currently no data for inter-rater or test-retest reproducibility in the long-term care setting.

Evaluation of an interactive, internet-based weight loss program : a pilot study

The Internet can access a large number of consumers in a more cost-effective manner than other information delivery channels. In this pilot study, we assessed whether an online weight reduction program including dietary advice plus exercise (ED) was more effective in reducing weight than an exercise-only program (EX) >12 weeks. Participants were randomized to either the ED or EX group and attended a center for anthropometric measurements and dietary assessment. Both groups wore a pedometer and set weekly goals to increase daily steps through an interactive Web site. The ED group set weekly dietary goals via the Web site and received tailored e-mail assistance. Seventy-three participants commenced and 53 (73%) completed the study [EX n = 26; ED n = 27; body mass index—mean (standard deviation): 29.7 (2.5) kg m^–2, age 46.3 (10.8); 21% male]. Percent weight changes were EX, 2.1 (0.6)% and ED, 0.9 (0.6)% (P = 0.15). Both groups increased their daily steps with no difference between groups. Only the ED group significantly reduced their energy intake. Despite a greater fall in energy intake reported by the ED group and a similar increase in physical activity in both groups, setting individual dietary goals did not enhance weight loss.

Victorian index of estuary condition : recommended themes and measures

Deakin University was engaged by the Department of Sustainability and Environment to develop an Index of Estuary Condition (IEC) for evaluating the environmental condition of Victorian estuaries. The Index will ultimately complement the existing Index of Stream Condition (ISC) by providing a consistent statewide assessment of the environmental condition of estuaries. This will better enable:

• Estuarine condition to be reported at regional, state and national levels.

• Prioritisation of resource allocation.

• Strategic evaluation of management interventions in estuaries.

Workshops involving participants with expertise in a variety of disciplines were convened to integrate learnings from assessment programs currently being developed interstate and overseas. This report synthesises and builds on the output from those workshops which:

• Identified key components (themes) of estuaries that contribute to estuarine condition.

• Contributed to development of a broad conceptual model for Victorian estuaries

• Identified possible measures of each theme

In keeping with the sub-indices of the ISC, six themes were identified for use in the IEC: Physical form, Hydrology, Water quality, Sediment, Flora and Fauna. Several measures within each theme are recommended to assess estuary condition.

Implementation of particular measures in the IEC partly depends on the investment required to both collect and interpret the required data. With regard to data collection, each measure was assessed according to whether there is an established sampling procedure, how frequently data need to be collected and the level of expertise required for collection and processing. For interpreting the data, measures were scored on whether baseline condition is established and whether descriptions and scores are developed which reflect the extent of deviation from that condition. These scores were used to indicate which measures are feasible to implement immediately and which require further investigation.

A trial of the recommended IEC measures in a selection of estuaries is recommended as it would provide an opportunity to test the measures and their suitability for application statewide. It is suggested that the trial is conducted in estuaries subject to various levels of threats within each of the four estuary classes described by Barton et al. (2008)
