Achieving impact in ergonomic research

People are central to system functioning and this role has been dramatically extended by new information technology. This makes possible the fundamental transformation of processes across systems of systems. Can Ergonomics research play an effective role in systems integration innovation? To have real world impact on such problems the system of R and D needs to sustain strong designs that address the functionality of socio-technical systems and support the implementation of innovations, taking into account the complexity of change, the importance of values of dignity and trust, and creating a common understanding amongst all stakeholders to enable design for operations. Strong research designs are more expensive, difficult, risky and prolonged than more commonly practiced weaker designs. They require active engagement with the industrial or service provider and involve overcoming cultural and other barriers to effective implementation and change. To create a virtuous cycle of research-generated impact it is necessary for strong designs to be well supported in the research community and for real world impact to be central to performance criteria of research excellence. Unfortunately neither of these criteria appear to be fulfilled. To ameliorate this, deficiencies in the full cycle of systems integration innovation need to be addressed.     

A systematic review on community-based interventions for elder abuse and neglect

Elder abuse and neglect is a societal issue that requires prevention and intervention strategies at the practice and policy level. A systematic review on the efficacy of community-based elder abuse interventions was undertaken to advance the state of knowledge in the field. The peer-reviewed literature between 2009 and December 2015 were searched across four databases. Two raters independently reviewed all articles, assessed their methodological quality, and used a modified Sackett Scale to assign levels of evidence. Four thousand nine hundred and five articles were identified; nine were selected for inclusion. Although there was Level-1 evidence for psychological interventions (n = 2), only one study on strategies for relatives (START) led to a reported decrease in elder abuse. There was Level-4 evidence for conservatorship, an elder abuse intervention/prevention program (ECARE), and a multidisciplinary intervention (n = 4), in which one study yielded significant decreases in elder abuse and/or neglect. The remaining three were classified as Level-5 evidence (n = 3) for elder mediation and multidisciplinary interventions. There are limited studies with high levels of evidence for interventions that decrease elder abuse and neglect. The scarcity of community-based interventions for older adults and caregivers highlights the need for further work to elevate the quality of studies.     

Adjusting for Change of Status in International Migration: Demographic Implications

The calculation of net immigration for the purpose of estimating the resident population in Australia is based on net permanent and long–term (12 months or more) movements into and out of the country. All international movements with duration of stay in Australia or travel abroad of less than 12 months (defined as short–term) are excluded. However, changes between short–term and long–term/permanent status can occur when people extend or shorten their stay or travel. Because net immigration is a significant component of Australia’s population growth (accounting for 40–50 per cent of annual growth), adjusting for these changes in migration status is thought to result in better estimates of net immigration and the resident population. The paper shows that adjusting for change of status can have a large impact on net immigration, particularly when the immigrant intake is small. Failure to adequately adjust for change of status can also lead to misleading conclusions about the relative contributions of net temporary and permanent movements to total net immigration. The effect on the resident population, however, is relatively small, being less than 1 per cent of the total population. The paper also addresses the question of how important it is for countries to adjust for change of migrant status in international migration statistics in the context of increasing international mobility.     

The use of formal inventory control models: A preliminary survey

Of the many papers and texts on the subject of inventory control, relatively few report the successful implementation of systems based on formal mathematical models developed with specific objectives in mind. This could be considered rather strange in the light of the relatively high number of papers reporting the development of models for dealing with a multitude of different hypothetical situations, and the widespread availability of computer systems capable of exploiting such models. Various reasons for this anomaly can be put forward. This paper reports the results of a preliminary survey designed to investigate this more deeply, and draws some necessarily tentative conclusions relating to factors contributing to the successful application of such systems.     

The effects of seasonal demand on depot location

Many of the cost functions associated with depot location algorithms assume an overall demand for a fixed period, usually one year. This paper describes an investigation into the effect of high seasonality within such demand figures on the optimal location of storage facilities. The preliminary results indicate that a more flexible approach for certain products could be worthwhile.     

Mixture modelling of recurrent event times with long-term survivors: Analysis of Hutterite birth intervals

We propose a mixture model that combines a discrete-time survival model for analyzing the correlated times between recurrent events, e.g. births, with a logistic regression model for the probability of never experiencing the event of interest, i.e., being a long-term survivor. The proposed survival model incorporates both observed and unobserved heterogeneity in the probability of experiencing the event of interest. We use Gibbs sampling for the fitting of such mixture models, which leads to a computationally intensive solution to the problem of fitting survival models for multiple event time data with long-term survivors. We illustrate our Bayesian approach through an analysis of Hutterite birth histories.     

An inconvenient truth: why evidence-based policies on obesity are failing Māori,Pasifika and the Anglo working class

Public health initiatives around obesity have generally worked well for middle class Australians and New Zealanders. This message has not had the same impact in Anglo working class areas and certain CALD communities, especially Māori and Pasifika, where obesity rates remain highest. This paper employs qualitative data from interviews with eighty-five Māori and Pasifika migrants to Australia to explore attitudes to food purchasing and consumption behaviours and associated health risks. It is evident the individual, medicalised approach to improving obesity rates has not been effective and there needs to be a new culturally responsive structural approach. This would require governments to prioritise population health over existing relationships with commercial food manufacturers – especially in relation to spatial domination of commercialised fast food outlets in low socio-economic status districts and in the areas of sports and education sponsorship. We also explore the assumptions of evidence-based health policy more generally, providing a critique of who is represented and served by the commercial solicitation and management of health research. This includes what constitutes ‘evidence’, who is conducting and funding the research, who appraises and compares the data and how is it interpreted and employed.     

Homosexual identity formation as a developmental process

Homosexual identity is conceptualized as a life-spanning developmental process that eventually leads to personal acceptance of a positive gay self-image and a coherent personal identity. Habermas' theory of ego development is utilized to provide a synthesis and understanding of the literature on the construction and maintenance of the homosexual identity. It is concluded that the homosexual identity generally emerges in a three-stage process in which the person progresses from: (1) an egocentric interpretation of homoerotic feelings to (2) an internalization of the normative, conventional assumptions about homosexuality to (3) a post-conventional phase in which societal norms are critically evaluated and the positive gay identity is achieved and managed. Developmental tasks associated with each stage are outlined in terms of their ego-integrative functions. Although the stages in the process of homosexual identity formation are theoretically the same for females and males, because of the paucity of research on the homosexual identity in females, this paper deals chiefly with males.     

The Promotion and Disruption of Community Service Delivery Systems

In this paper, we report data drawn from a larger project on the functioning of the Queensland community service delivery system, particularly that providing services to people with disabilities. Our reasoning for focusing at this level is that, from the service user's perspective, support is derived from the service delivery system, not just individual service providers. Defining the service delivery system as formal services and informal support networks, we undertook interviews and focus groups with service providers in six areas in Queensland: inner urban, outer urban, rural and remote. The period on which we report is one in which considerable reform activity had been undertaken by funding bodies of the Commonwealth and State governments. We report on those factors we identified which promote the integrated functioning of the service delivery system, as well as those factors that disrupt it. We conclude with a brief evaluative analysis of the current status of the system.
