Given the importance of season ticket holders (STH) to sporting organisations, we empirically examine a scale for measuring their attitudes to the season ticket product. This involved identifying through qualitative research and past literature, the various elements that are perceived to comprise the season ticket package and developing items to measure STH attitudes to them. The season ticket package was decomposed into six key components, closely mirroring past research. A survey of over 2,500 STH of a professional sporting organisation was then conducted, incorporating items related to these six areas, overall satisfaction and disconfirmation of expectations. The results of Exploratory Factor Analysis on those items is presented here, with results suggesting the items are valid measures of season ticket holder attitudes that capture the breadth of the STH experience.

The paper examines dimensions of organizational justice construct in a public sector context, utilizing an organizational justice measure developed and validated by Colquitt (2001). The present study substantiates the existing claims about the independence of interactional justice and the division of interactional justice into interpersonal and informational justice. The present investigation also contributes to the justice literature by providing evidence of a new factor, which is called procedural voice justice to reflect the possible association with the concept of voice effect. Although voice has been examined extensively in the justice research as an antecedent of procedural justice, little is known about if and how voice might integrate into procedural justice construct. The study proposes that future justice research further investigate dimensionality of organisational justice and aspire to developing a common measure of the justice construct.

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.

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.

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.

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.

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.

A consistent and integrated approach to nature conservation across the landscape and regardless of tenure is widely recognised as essential in ensuring the effective conservation of biodiversity. 'Multi-tenure reserve networks', which incorporate public and private lands managed for conservation, are considered a means of achieving landscape scale conservation. Biosphere Reserves (BR) and Conservation Management Networks (CMN) are characteristic models in Australia. This thesis aims to evaluate the role of such networks in protecting biodiversity, specifically by: (1) analysing the spatial configuration (size, shape, connectivity) of networks and their individual components; (2) evaluating the contribution of networks (in real terms and in reporting procedures) to biodiversity conservation objectives; (3) analysing the influence of the attitudes and perceptions of land managers on the functionality of networks; and (4) evaluating the influence of coordinating bodies on network functionality. In order to account for deficiencies in existing classifications of conservation lands, a new classification system was developed for this thesis - the Conservation Lands Classification. This classification incorporates conservation mechanisms on public and private lands and forms the basis for comparing network components in three Australian case studies - the Bookmark BR located in the Murray Mallee of South Australia, the Gippsland Plains CMN on the eastern Gippsland Plains of Victoria and the Grassy Box Woodlands CMN across the inland slopes of New South Wales. The spatial configuration of individual components within networks was measured using spatial analysis techniques within a geographic information system (GIS). GIS was also used to measure the contribution that networks made to a comprehensive, adequate and representative reserve system through the ecosystems they protected. The attitudes and perceptions of landowners and managers within the networks were obtained using questionnaires. Questionnaires were also sent to network coordinators. Statistical and descriptive analysis was conducted on the results. The sizes of individual components varied markedly between the three networks, however within each network public reserves were on average larger than private conservation lands. Although levels of physical connectivity varied between networks, Bookmark BR and Gippsland Plains CMN showed greater similarity to each other than to the Grassy Box Woodlands CMN. The findings raise important questions about the real and perceived differences in the BR and CMN models. All networks, and particularly those components outside the public protected area estate, contributed to enhancing the protection of ecosystems unrepresented or under-represented in the reserve system, although the extent of this contribution varied between networks. Trade-offs between reserve design efficiency and a contribution to a comprehensive, adequate and representative reserve system were evident between networks. Bookmark BR was characterised by high connectivity, strong reserve design integrity but a lower contribution to protecting under-reserved ecosystems, whereas the opposite was evident in the Grassy Box Woodlands CMN. Over 88% of managers considered their involvement in multi-tenure reserve networks to be a positive or very positive experience. A lack of resources and time for management were considered major limitations of these networks. The majority (80%) of private land managers within networks were willing to be included in a national reserve system of conservation lands. This has important implications for the Australian National Reserve System, which currently incorporates mostly public land. The changing nature of the network coordination arrangements suggests an organic fluid evolution of network structures is likely, contrasting with the desire for legalistic and administrative rigidity promoted by government agencies. The thesis concludes that all the networks studied contribute in varying degrees to biodiversity conservation. The key factors influencing the current and potential contribution that such networks make are: (1) the aims, directions and restrictions set by or imposed upon the coordinating body; and (2) the biophysical nature of the surrounding bioregion and resultant historical land use and tenure pattern. Although the successful operation of such 'multi-tenure' networks ultimately relies on the willing participation of private landholders, ongoing institutional support is likely to be required for maintaining networks in the longer term. Considering networks are increasingly formed outside of the influence of government institutions, this presents a significant challenge for effective coordinated conservation.
