Doubling fish exports or garment exports : which would benefit the Fijian economy most? Evidence from a computable general equilibrium model

The need to diversify Fiji's export base has been identified as an important avenue for reducing Fiji's vulnerabilities in international trade. This paper poses the question: Doubling fish exports or garment exports: which would be most beneficial for the Fijian economy? To achieve the goal of this paper, the computable general equilibrium model is used, this being at the forefront of research on 'impact studies'. The main finding is that when garment exports and fish exports are doubled, the benefits to the Fijian economy are greater from garment exports, suggesting that the latter has stronger linkages with the rest of the economy. On the basis of this finding, policymakers should divert resources towards sustaining the garment industry whose future is uncertain due to expiring trade agreements and unstable economic policies.

The Health Education Impact Questionnaire (heiQ): An outcomes and evaluation measure for patient education and self-management interventions for people with chronic conditions

Objective: This paper describes the development and validation of the Health Education Impact Questionnaire (heiQ). The aim was to develop a user-friendly, relevant, and psychometrically sound instrument for the comprehensive evaluation of patient education programs, which can be applied across a broad range of chronic conditions.

Methods: Item development for the heiQ was guided by a Program Logic Model, Concept Mapping, interviews with stakeholders and psychometric analyses. Construction (N = 591) and confirmatory (N = 598) samples were drawn from consumers of patient education programs and hospital outpatients. The properties of the heiQ were investigated using item response theory and structural equation modeling.

Results: Over 90 candidate items were generated, with 42 items selected for inclusion in the final scale. Eight independent dimensions were derived: Positive and Active Engagement in Life (five items, Cronbach's alpha (α) = 0.86); Health Directed Behavior (four items, α = 0.80); Skill and Technique Acquisition (five items, α = 0.81); Constructive Attitudes and Approaches (five items, α = 0.81); Self-Monitoring and Insight (seven items, α = 0.70); Health Service Navigation (five items, α = 0.82); Social Integration and Support (five items, α = 0.86); and Emotional Wellbeing (six items, α = 0.89).

Conclusion:The heiQ has high construct validity and is a reliable measure of a broad range of patient education program benefits.

Practice Implications: The heiQ will provide valuable information to clinicians, researchers, policymakers and other stakeholders about the value of patient education programs in chronic disease management.

Developing and validating a questionnaire to measure spirituality : a psychometric process

The purpose of the paper is to describe the processes undertaken to evaluate the psychometric properties of a questionnaire developed to measure spirituality and examine the relationship between spirituality and coping in young adults with diabetes.

The specific validation processes used were: content and face validity, construct validity using factor analysis, reliability and internal consistency using test-retest reliability and Cronbach’s alpha correlation coefficient.

The exploratory factor analysis revealed four factors: self-awareness, the importance of spiritual beliefs, spiritual practices, and spiritual needs. The items on the Spirituality Questionnaire (SQ) revealed factor loading ≥ 0.5. Reliability processes indicated that the SQ is reliable: Cronbach’s alpha 0.94 for the global SQ and between 0.80-0.91 for the four subscales. Test-retest statistic examination revealed stability of the responses at two time points 10 weeks apart.

The final questionnaire consists of 29 items and the psychometrics indicated that it is valid and reliable.

Assessing risk for sexual offenders in New Zealand : development and validation of a computer-scored risk measure

A growing research base supports the predictive validity of actuarial methods of risk assessment with sexual offenders. These methods use clearly defined variables with demonstrated empirical association with re-offending. The advantages of actuarial measures for screening large numbers of offenders quickly and economically are further enhanced when the variables used can be extracted from existing electronic databases. This study reports the results of applying a computerized set of historical variables with a sample of 1,133 male sexual offenders released from prison by the New Zealand Department of Corrections. Area under the curve figures of 0.70-0.78 were obtained over periods of 5 to 15 years, reflecting a significant level of association with sexual recidivism. Detected rates of re-offending across risk levels were comparable to those previously reported for the Static-99. Rates of sexual re-offending by child molesters for all sexual offences and offences against child victims are reported separately.

Envelopment methodology to measure and compare subcontractor productivity at the firm level

This paper describes a conceptual approach to measure and compare productivity of resource utilization at the firm level, adapting a set of techniques known as Data Envelopment Analysis (DEA). Within this approach, the paper addresses the issues of multiple inputs and multiple outputs of a construction firm, level of detail for data collection, and the required transformations to correct for differences among projects. In particular, we focus on the resource management of subcontractors. Subcontractors manage multiple, concurrent projects and must allocate limited resources across these projects. Interaction between projects and resource allocation creates non-linear effects, and therefore the productivity of the firm is not simply the productivity of its projects. The proposed measurement methodology will allow assessment of the impact of different management policies (including many of those proposed by lean construction researchers) on firm performance. It is hoped that this novel approach to productivity measurement will help subcontractors identify efficient practices and superior management policies, and will promote adoption of these policies.

How should we measure indigenous entrepreneurship? A search for explanatory variables

In Canada and elsewhere around the world Indigenous Peoples are struggling to rebuild their ‘nations’ and improve the socioeconomic circumstances of their people. We are embarking on a program of research in an effort to understand this phenomenon and to inform the process. In this paper we (i) explore the approach to development being adopted by Indigenous people in Canada; (ii) conduct a preliminary literature review; (iii) identify input indicators of entrepreneurship and business development capacity, process measures of development activity and an output indicator of development effectiveness and (v) identify the information available from secondary sources relating to these indicators and the gaps in information that will have to be filled by primary research.

Population norms and meaningful differences for the Assessment of Quality of Life (AQoL) measure

Objective: The Assessment of Quality of Life (AQoL) instrument is widely used in Australian health research. To assist researchers interpret and report their work, this paper reports population and health status norms, general minimal important differences (MIDs) and effect sizes.

Method: Data from the 1998 South Australian Health Omnibus Survey (n=3,010 population-based respondents) were analysed by gender, age group and health status. Data from four other longitudinal studies were analysed to obtain estimated MIDs.

Results: The mean (SD) AQoL utility score was 0.83 (0.20). Gender and age subgroup differences were apparent; the mean scores for women were consistent until their 50s, when scores declined. Greater variability was observed for males whose scores declined more slowly but consistently between 40–80 years. For both genders, those aged 80+ years had the lowest scores When assessed by health status, those reporting excellent health obtained the highest utility scores; progressive declines were observed with decreasing health status. Effect sizes of 0.13 or greater may reflect important differences between groups A difference in AQoL scores of 0.06 utility points over time suggests a general MID.

Conclusions: AQoL population norms, MIDs and effect sizes can be used as reference points for the interpretation of AQoL data. These findings add to the growing evidence that the AQoL is a robust and sensitive measure that has wide applicability.

Implications: The availability of population norms will assist researchers using the AQoL to more easily interpret and report their work.
