An evaluation of self-report measures of cognitive distortions and empathy among Australian sex offenders

The modification of deviant cognitions and the enhancement of victim empathy are central components in many treatment programs for sex offenders. There appear to be three broad problems with self-report measures of these factors: variations in the psychometric evaluation of measures; the transparency of items and thus the likely influence of social desirability; and the difficulty of determining which measures are specific to particular types of sex offenders. The aim of this study was to investigate these three issues among child molesters (CMs), and men convicted of sex offences against adults (ASOs). Data were collected from 36 CMs and 31 ASOs and from two comparison groups (33 men convicted of nonsexual offences and 40 nonoffenders from the community), to assess the reliability (internal and test-retest) and validity (discriminant, construct, and face) of measures, the influence of sexual social desirability on responding and the specificity of measures to both sex offender groups. Collectively, the results raise issues related to the assessment of sex offenders that require further investigation. They also have theoretical implications about the relationship between cognitive and emotive processes among sex offenders.

Population based intervention to change back pain beliefs and disability : three part evaluation

Objective To evaluate the effectiveness of a population based, state-wide public health intervention designed to alter beliefs about back pain, influence medical management, and reduce disability and costs of compensation. Design Quasi-experimental, non-randomised, non-equivalent, before and after telephone surveys of the general population and postal surveys of general practitioners with an adjacent state as control group and descriptive analysis of claims database. Setting Two states in Australia Participants 4730 members of general population before and two and two and a half years after campaign started, in a ratio of2:1:1; 2556 general practitioners before and two years after campaign onset. Main outcome measures Back beliefs questionnaire, knowledge and attitude statements about back pain, incidence of workers' financial compensation claims for back problems, rate of days compensated, and medical payments for claims related to back pain and other claims. Results In the intervention state beliefs about back pain became more positive between successive surveys (mean improvement in questionnaire score 1.9 (95% confidence interval 1.3 to 2.5), P<0.001 and 3.2 (2.6 to 3.9), P < 0.001, between baseline and the second and third survey, respectively). Beliefs about back pain also improved among doctors. There was a clear decline in number of claims for back pain, rates of days compensated, and medical payments for claims for back pain over the duration of the campaign. Conclusions A population based strategy of provision of positive messages about back pain improves population and general practitioner beliefs about back pain and seems to influence medical management and reduce disability and workers' compensation costs related to back pain.

Calpain 3 gene expression in skeletal muscle is associated with body fat content and measures of insulin resistance

OBJECTIVE: To investigate whether skeletal muscle gene expression of calpain 3 is related to obesity and insulin resistance.

DESIGN: Cross-sectional studies in 27 non-diabetic human subjects and in Psammomys obesus, a polygenic animal model of obesity and type 2 diabetes.

MEASUREMENTS: Expression of CAPN3 in skeletal muscle was measured using Taqman fluorogenic PCR. In the human subjects, body composition was assessed by DEXA and insulin sensitivity was measured by euglycemic-hyperinsulinemic clamp. In Psammomys obesus, body composition was determined by carcass analysis, and substrate oxidation rates, physical activity and energy expenditure were measured by whole-body indirect calorimetry.

RESULTS: In human subjects, calpain 3 gene expression was negatively correlated with total (P=0.022) and central abdominal fat mass (P=0.034), and with blood glucose concentration in non-obese subjects (P=0.017). In Psammomys obesus, calpain 3 gene expression was negatively correlated with circulating glucose (P=0.013) and insulin (P=0.034), and with body fat mass (P=0.049). Indirect calorimetry revealed associations between calpain 3 gene expression and carbohydrate oxidation (P=0.009) and energy expenditure (P=0.013).

CONCLUSION/INTERPRETATION: Lower levels of expression of calpain 3 in skeletal muscle were associated with reduced carbohydrate oxidation and elevated circulating glucose and insulin concentrations, and also with increased body fat and in particular abdominal fat. Therefore, reduced expression of calpain 3 in both humans and Psammomys obesus was associated with phenotypes related to obesity and insulin resistance.

The impact of work settings on organisational performance measures in built facilities

A current facilities management discourse seeks to discover how the built environment promotes or retards organisational change. However, whether or not significant change arises at all is yet to be definitively established. Hence, a contribution to the school of thought in this direction is considered important. This research investigated organisational performance relative to innovative work settings. The aim of the study was to determine whether organisational performance and, hence, change are indeed brought about by innovative work settings. A sample of 102 work settings was studied, and several null hypotheses on innovative work settings and organisational performance were tested using the Kruskal-Wallis H test. Although subtle shifts were observed in the aspects of organisational performance that seem predicated on innovative work settings, to some extent the proposition that the physical properties and design of the workplace can influence organisational performance was validated.

The management of adolescents at risk of suicide by Australian general practitioners: issues in practice and confidence

This study involved an anonymous survey of 41Victorian GPs regarding their diagnostic and treatment practices with adolescent patients with depression and/or suicide ideation. The results indicated that the majority of respondents correctly diagnosed the level of depression and the risk of suicide in a case scenario. Although they commonly asked some of the questions related to an assessment of suicide risk, they rarely conducted a comprehensive risk assessment and the level of referral to telephone and internet crisis services was poor. Most GPs indicated a lack of confidence in their ability to detect and manage depression and suicide in this population and strongly emphasized a need for more training.

Linking environmental uncertainty to non-financial performance measures and performance : a research note

Several previous research studies have reported mixed results concerning the direct association between non-financial performance measures and  performance. The presence of environmental uncertainty on this relationship has not been established. This paper makes a contribution to this area by proposing that it is in conditions of environmental uncertainty that non-financial measures are most useful in improving organizational performance. It analyses empirical data from a sample of New Zealand manufacturing organizations to test the hypothesis that non-financial measures of performance would lead to improved organizational performance under conditions of increased environmental uncertainty. Multiple regression analysis of the data suggests that performance should be a declining function of the size of the ‘mismatch’ between an organization's environment and use of the different combinations of non-financial performance measures. Further, the paper concludes that prior mixed results may be attributed to the omission of environmental uncertainty.

Non-equivalence of direct and indirect measures of unrealistic optimism

Individuals typically believe that they are less likely than the average person to experience negative events. Such “unrealistic optimism” (UO) has been assessed in two ways: directly (via a single question, requiring comparison of own risk to that of the average person) and indirectly (via separate questions about own risk and that of the average person). The study examined the equivalence of the direct and indirect measures of female students' UO for unwanted pregnancy. Participants (N = 120) answered questions about their own risk, that of the average female student, and their own risk relative to that of the average female student; responses and response times were recorded. There was only a moderate association between direct- and indirect-UO. Direct-UO was strongly associated with estimate of own risk, but only moderately associated with estimate of the average student's risk. Response times for the comparative risk and own risk questions did not differ, but participants took significantly longer to answer the question about average student's risk. The results suggest that the two measures of UO are not equivalent, but, rather, that individuals answering a comparative risk question focus mainly on their own risk, at the expense of that of the average person.

Multifactor productivity measures of construction sectors using OECD input-output database

This research develops a new productivity measurement framework for the construction sector in the light of an input-output table. Three group multifactor productivity indicators are formulated based on the multiplier concepts in the input-output analysis. This measurement framework focuses on the intro-industry flows of products and considers the direct and indirect effects of input and output. Moreover, this framework enables us to measure the multifactor productivity of a specific sector systematically. Historical analyses and international comparisons are carried out to indicate the differences of the productivity of the construction sectors in seven selected countries, using the newly published OECD input-output database. Research findings are expected to clarify how technological, organizational and political factors affect the productivity growth, enabling the policy makers, construction businesses and researchers to quantify the competitive ability of the construction sector.

Linkage measures of the construction sector using the hypothetical extraction method

The hypothetical extraction method (HEM) is used to extract a sector hypothetically from an economic system and examine the influence of this extraction on other sectors in the economy. Linkage measures based on the HEM become increasingly prominent. However, little construction linkage research applies the HEM. Using the recently published Organisation for Economic Co-operation and Development input-output database at constant prices, this research applies the HEM to the construction sector in order to explore the role of this sector in national economies and the quantitative interdependence between the construction sector and the remaining sectors. The output differences before and after the hypothetical extraction reflect the linkages of the construction sector. Empirical results show a declining trend of the total, backward and forward linkages, which confirms the decreasing role of the construction sector with economic maturity over the examined period from a new angle. Analytical results reveal that the unique nature of the construction sector and multifold external factors are the main reasons for the linkage difference between countries. Moreover, hypothesis-testing results consider statistically that the extraction structures employed in this research are appropriate to analyse the linkages of the construction sector.

Lay people's views of school food policy options: associations with confidence, personal values and demographics

A random population survey administered by mail to examine lay people's views of children's food policies and their associations with demographics, personal values and confidence in authorities was conducted among adults in Victoria, Australia. Three hundred and seventy-seven people responded (response rate 57.6%). The questionnaire contained 35 items about children's healthy eating policy options plus details like personal values, confidence and demographic items. There was widespread support for healthy school food policies. The strongest support was for life skills education and school-based nutrition and physical education programmes. Many age-related associations indicated that people >48 years were more in favour of healthy eating policies than younger people. There were fewer statistically significant associations with parent status and sex. In contrast, many associations showed that respondents with strong equity–harmony values and those with least confidence in the authorities were most in favour of healthy eating policies for schoolchildren. It is concluded that there is widespread support for school-based health and nutrition education and for active school food policies. However, differences between demographic and values groups suggest the need for caution in the promotion of public health nutrition initiatives among schoolchildren.

Food insecurity, malnutrition and mortality in Maewo and Ambae islands, Vanuatu

Context: This paper reports on findings from the ex-post evaluation of the Maewo Capacity Building project in Maewo Island, Vanuatu, which was funded by World Vision Australia.
Objectives: To examine the extent to which the infrastructure and systems left behind by the project contributed to the improvement of household food security and health and nutritional outcomes in Maewo Island, using Ambae Island as a comparator.
Setting: Two-stage cluster survey conducted from 6 to 20 July 2004, which included anthropometric measures and 4.5-year retrospective mortality data collection.
Participants: A total of 406 households in Maewo comprising 1623 people and 411 households in Ambae comprising 1799 people.
Main outcome measures: Household food insecurity, crude mortality rate (CMR), under-five mortality rate (U5MR) and malnutrition prevalence among children.
Results: The prevalence of food insecurity without hunger was estimated at 15.3%
(95% confidence interval (CI): 12.1, 19.2%) in Maewo versus 38.2% (95% CI: 33.6, 43.0%) in Ambae, while food insecurity with hunger in children did not vary by location. After controlling for the child’s age and gender, children in Maewo had higher weight-for-age and height-for-age Z-scores than children of the same age in Ambae. The CMR was lower in Maewo (CMR ¼ 0.47/10 000 per day, 95% CI: 0.39, 0.55) than in Ambae (CMR ¼ 0.59/10 000 per day, 95% CI: 0.51, 0.67) but no difference existed in U5MR. The major causes of death were similar in both locations, with frequently reported causes being malaria, acute respiratory infection and
diarrhoeal disease.
Conclusions: Project initiatives in Maewo Island have reduced the risks of mortality and malnutrition. Using a cross-sectional ‘external control group’ design, this paper demonstrates that it is possible to draw conclusions about project effectiveness where baseline data are incomplete or absent. Shifting from donor-driven evaluations to impact evaluations has greater learning value for the organisation, and greater value when reporting back to the beneficiaries about project impact and transformational
development in their community. Public health nutritionists working in the field are well versed in the collection and interpretation of anthropometric data for evaluation of nutritional interventions such as emergency feeding programmes. These same skills can be used to conduct impact evaluations, even some time after project completion, and elucidate lessons to be learned and shared. These skills can also be applied more widely to projects which impact on the longer-term nutritional status of
communities and their food security.

Reliability of moderate-intensity and vigorous physical activity stage of change measures for young adults.

Background
The purpose of this study was to examine the reliability of stage of change (SOC) measures for moderate-intensity and vigorous physical activity in two separate samples of young adults. Staging measures have focused on vigorous exercise, but current public health guidelines emphasize moderate-intensity activity.
Method
For college students in the USA (n = 105) and in Australia (n = 123), SOC was assessed separately on two occasions for moderate-intensity activity and for vigorous activity. Test–retest repeatability was determined, using Cohen’s kappa coefficient.
Results
In both samples, the reliability scores for the moderate-intensity physical activity staging measure were lower than the scores for the vigorous exercise staging measure. Weighted kappa values for the moderate-intensity staging measure were in the “fair to good” range for both studies (0.50 and 0.45); for the vigorous staging measure kappa values were “excellent” and “fair to good” (0.76 and 0.72).
Conclusions
There is a need to standardize and improve methods for staging moderate-intensity activity, given that such measures are used in public health interventions targeting HEPA (health-enhancing physical activity).
