Some New Perspectives on Early Australian Social Work

Abstract

The present article re-examines several aspects of the early history of Australian social work. Using primary sources that recently underpinned a PhD thesis, the paper suggests that the traditional historical interpretation of the roles of the Charity Organisation Society (COS) and the British model of lady almoning as the foundation pillars of social work, while applicable to the establishment of social work in Victoria, had less relevance in the case of New South Wales. Second, the present article highlights the valuable role played by a group of Catholic women trained in social work in the foundation decades of the profession in Australia. Led by Professor Norma Parker, this small cohort made a distinctive contribution in an array of social work arenas, including their church, subjects that hitherto have been largely overlooked in the literature.     

Eco-Six Sigma: integration of environmental variables into the Six Sigma technique

The impressive results achieved by several companies through the Six Sigma technique have motivated other organisations to follow their footsteps in search for competitiveness. As noticed in the literature, most Six Sigma projects in manufacturing have aimed to obtain process enhancements, focusing mostly on optimising product cycle times with almost none taking into consideration environmental aspects as part of their developments. Furthermore, organisations have been worrying worldwide about environmental issues, seeking to foster their eco-efficiency. As a result, the main objective of this paper is to formally introduce the environmental considerations into the Six Sigma technique by proposing a procedure to incorporate environmental variables into the DMAIC process as a way to increase the eco-efficiency level of the firms. Based on the literature review, a conceptual procedure to incorporate environmental variables into the Six Sigma DMAIC technique is proposed. To verify its possible application to real-life situations an action research was developed and could verify that the traditional Six Sigma approach (dealing only with the manufacturing process variables) was capable of improving the eco-efficiency level of the process area under study by 11%. The consideration of the environmental variables as part of the DMAIC technique as per the proposed approach allowed an additional 20% gain, which demonstrates its adequacy to increase the eco-efficiency level of the manufacturing area under evaluation.     

Coverage with k-transmitters in the presence of obstacles

For a fixed integer k≥0, a k-transmitter is an omnidirectional wireless transmitter with an infinite broadcast range that is able to penetrate up to k “walls”, represented as line segments in the plane. We develop lower and upper bounds for the number of k-transmitters that are necessary and sufficient to cover a given collection of line segments, polygonal chains and polygons.     

Realistic Empathy and Active Nonviolence Confront Political Reality

This article employs three concepts to integrate the prior articles in this issue: political reality, realistic empathy, and active nonviolence. People of wealth and power define political reality, making their interests coterminous with national interests. Episodic and structural violence are used to maintain political reality. The prior articles report on diverse means to counter political reality, mitigate the effects of violence and lay the groundwork for peacebuilding. Basic to those means are realistic empathy and active nonviolence.     

PrEP Awareness in the Context of HIV/AIDS Conspiracy Beliefs Among Black/African American and Hispanic/Latino MSM in Three Urban US Cities

ABSTRACT

We examined HIV conspiracy beliefs and PrEP awareness in a convenience sample of minority MSM. Participants in three cities completed a behavioral self-assessment on sociodemographics, PrEP awareness, and HIV/AIDS conspiracy beliefs. HIV/AIDS conspiracy beliefs were more common among Black than Latino MSM (58% vs. 42%, p < .05), and among younger men than older men (age 18–29 (50%), 30–39 (22%), 40+ (28%); p < .05). PrEP awareness co-occurred with conspiracy belief less (37%) than with non-belief (63%, p < .05), persisting in multivariable regression (aOR = 0.52, 95% CI = 0.38–0.71). This relationship suggests that current HIV care and prevention messaging is either inaccessible or not credible to some minority subpopulations.     

A New Formulation For The Multinomial Selection Problem

The two approaches to a multinomial ranking and selection problem (for selecting the t best cells out of k are combined to form a new apprach. In this new approach there is a preference zone (PZ) and an indifference zone (IZ), and the concept of a correct selection (CS) is defined differentlv in eac of these zones. Lower bounds for the probability of correct selection p(CS) are then guaranteed in each of these zones using a single experiment. The procedure on the ordered frequencies in the cells. The principle tool used to derive expressins for the p(CS). for the expected sample size EN, for the expected subsct size ES and for other probabilities. is the Dirichlet integral (Type 2) which was recent tabulated. These Dirichlet integrals are used to prove that the multiplicative slippage configuratin is leas favorable in the PZ and, for t = l, that the IZ. Numerical calculations are carried out for an illustrative example but extensive tables are not yet avalable

     

Asymmetric endogenous prize contests

We consider a two-player contest in which one contestant has a headstart advantage, but both can exert further effort. We allow the prize to depend on total performance in the contest and consider the respective cases in which efforts are productive and destructive of prize value. When the contest success function takes a logit form, and marginal cost is increasing in effort, we show that a Nash equilibrium exists and is unique both in productive and destructive endogenous prize contests. In equilibrium, the underdog expends more resources to win the prize, but still his probability of winning remains below that of the favorite. In a productive contest, the underdog behaves more aggressively and wins the prize more often in comparison to a fixed-value contest. Thus, the degree of competitive balance—defined as the level of uncertainty of the outcome—depends upon the (fixed or endogenous) prize nature of the contest.     

Using civil representation to reduce delinquency among troubled youth

Team Child is designed to provide civil legal representation for very troubled delinquent youth to improve their access to needed education programs, mental health services, and family services. Better provision of these services is intended to reduce delinquency and potentially avoid the long-term incarceration of these youth. This article uses an incidental truncation model to evaluate two Team Child programs in Florida. The authors find the programs not to be effective in reducing recidivism among the youth but to be effective in reducing the arrest rate of the recidivating juveniles. The results indicate a reduction of 11% to 23% of arrests after treatment for the Team Child group.
