Would Bigger Councils Yield Scale Economies in the Greater Perth Metropolitan Region? A Critique of the Metropolitan Local Government Review for Perth Local Government

Forced amalgamation is a ubiquitous feature of Australian local government reform – compulsory council consolidation programs have occurred in all states and territories, with the sole exception of Western Australia. However, the Final Report of the Metropolitan Local Government – released in October 2012 – called for a reduction of about 60 per cent of the local authorities in the Greater Perth metropolitan area. The Western Australian Government responded by announcing that the number of Perth councils will fall from 30 to 14 from 1 July 2015. The Final Report recommended amalgamation on seven main counts, including scale economies. However, apart from citing work on Tasmania by commercial consultants Deloitte Access Economics (DAE) (2011), no econometric evidence was produced in support of claims on scale economies. This paper seeks to remedy this deficiency by estimating a number of econometric models on the impact of amalgamation on Perth local government. The results of our empirical modelling suggest that scale economies, cost savings and other pecuniary gains are largely illusory. Indeed, only two of the ten main local government functions provide evidence to suggest potential economies of scale.     

Using sketch drawing to induce inconsistency in liars

Purpose. Consistency as a cue to detecting deception was tested in two experiments using sketch drawing and verbal reports in repeated interviews. Liars were expected to be less consistent than truth‐tellers. Methods. In Expt 1, 80 undergraduate students reported truthfully or deceptively about an alleged lunch date – they sketched the layout of the restaurant and then answered spatial questions about objects in the restaurant. Ratings were given for the consistency between sketches and verbal reports. In Expt 2, 34 undergraduate students reported truthfully or deceptively about completing a series of unrelated tasks – they answered spatial questions about objects in a room and then sketched the layout of the room. Proportions were calculated for the consistency between verbal reports and sketches. Results. Expt 1. Liars were rated as less consistent than truth‐tellers. Up to 80% of truth‐tellers and 70% of liars could be correctly classified. Expt 2. Liars were less consistent than truth‐tellers on consistency proportions. Up to 100% of truth‐tellers and 77% of liars could be correctly classified. Conclusions. Using sketches to induce inconsistency may be a reliable, resource efficient way to help investigators detect deception.     

Preliminary evaluation of the persistence of organic gunshot residue

The organic components of gunshot residue (OGSR, also called firearms discharge residue (FDR) or cartridge discharge residue (CDR)) have been studied and discussed in the literature. These residues, consisting of particulates such as burned and unburned powder as well as molecular compounds, are rarely used in casework except for purposes such as shooting reconstructions. Molecular compounds that survive the firing event or that are created as a result of the firing event could, with focused research and development, open a new avenue for forensic gunshot residue analysis. In this study, the persistence of organic gunshot residue was evaluated using diphenylamine (DPA) as a target analyte and ion mobility spectrometry (IMS) as the detection system. Samples were collected from hands using a solvent swabbing technique and the swab was analyzed using direct thermal desorption for sample introduction into the IMS. OGSR was found to persist for at least 4h. Although DPA is a widely used industrial compound, analysis of numerous blank and background samples (n～100) did not show any significant response for DPA using this detector. Variations were noted among individuals and as such, the data set does not support estimation of a half-life as has been done for traditional primer residues. No secondary transfers were observed, suggesting the possibility of skin adhesion via interactions between the lipophilic organic compounds and skin lipids. IMS proved valuable as a means of generating patterns for forensic pattern matching and shows promise as a screening tool applied to firearms discharge.     

The self-regulation model of sexual offending: Relationship to risk and need

In the present study, we evaluated the validity and utility of the self-regulation model in a sample of 275 adult male sexual offenders treated within the Correctional Service of Canada (CSC). Individuals following different self-regulation pathways, as delineated in the SRM, were compared on offence characteristics, static and dynamic risk measures, and various treatment targets. Multivariate analyses revealed that, in general, offenders guided by approach-motivated goals exhibited more problematic offence characteristics as well as greater risk and treatment need than individuals guided by inhibitory goals. However, several other important distinctions were noted across offenders with different goals and strategies toward offending. These findings highlight the main importance of utilizing a comprehensive and multidimensional offence process model that emphasizes multiple routes to offending in sexual offender treatment. Implications of these findings for the effective assessment and rehabilitation of sexual offenders are discussed.     

Predicting Phenotype from Genotype: Normal Pigmentation*

Abstract: Genetic information in forensic studies is largely limited to CODIS data and the ability to match samples and assign them to an individual. However, there are circumstances, in which a given DNA sample does not match anyone in the CODIS database, and no other information about the donor is available. In this study, we determined 75 SNPs in 24 genes (previously implicated in human or animal pigmentation studies) for the analysis of single‐ and multi‐locus associations with hair, skin, and eye color in 789 individuals of various ethnic backgrounds. Using multiple linear regression modeling, five SNPs in five genes were found to account for large proportions of pigmentation variation in hair, skin, and eyes in our across‐population analyses. Thus, these models may be of predictive value to determine an individual’s pigmentation type from a forensic sample, independent of ethnic origin.     

Social Network Analysis to evaluate organisational networks on sexual health and rights

There are many challenges in evaluating international networks. The use of conventional tools can be difficult and often provides less than useful information. Social Network Analysis offers benefits for network evaluators by allowing for documentation and analysis of inter-relationships between individuals and organisations. This paper describes the use of this approach in the evaluation of a major international project entitled the Global Dialogues on Sexual Health and Well-being. It highlights the value of maps in enabling clear visual representations of networks, the identification of areas needing greater focus and the basis on which networks are constructed.

Analyse des réseaux sociaux pour évaluer les réseaux organisationnels sur les droits et la santé génésiques

L’évaluation des réseaux internationaux présente de nombreux défis. L'utilisation d'outils conventionnels peut être difficile et fournit souvent des informations qui ne sont pas des plus utiles. L'analyse des réseaux sociaux comporte des avantages pour les évaluateurs des réseaux, car elle permet la documentation et l'analyse des corrélations entre individus et organisations. Cet article décrit l'utilisation de cette approche dans l’évaluation d'un important projet international intitulé Global Dialogues on Sexual Health and Wellbeing (Dialogues mondiaux sur la santé et le bien-être génésiques). Il met en relief la valeur des cartes pour permettre des représentations visuelles claires des réseaux, l'identification de zones nécessitant un axe central plus marqué et la base sur laquelle les réseaux sont construits.

RHETORIC AND REALITY IN THE REFORM OF JUVENILE JUSTICE POLICY

In the 1960s and 1970s dissatisfaction with the administration of juvenile justice led to a reform movement which advocated "diversion, deinstitutionalization," and the decriminalization of status offenses as strategies to reduce the harmfulness of official contacts. This paper argues not only that these reforms have not been successfully implemented, but also that the traditional system has been maintained and extended. Explanations for the failure of these reforms are offered and a new direction is suggested.
