Communitarianism as a Blind Alley? A Reply to Lacey and Frazer

This article seeks to challenge the interpretation of communitarianism offered by Lacey and Frazer (Politics, Vol. 14 No.2). By developing a theory of community it is possible to overcome the problems which they highlight, and to demonstrate that communitarianism, properly understood, is a philosophy which can frame much useful debate in political theory.     

A quantitative PCR assay for the assessment of DNA degradation in forensic samples

A multiplex quantitative PCR assay has been designed to amplify target sequences of different length, which allows for the assessment of DNA degradation in samples of forensic interest. The targets were chosen to provide quantification and fragment length information relevant to the STR amplification targets commonly used for forensic genotyping. The longer target (nuTH01, 170-190 bp) spans the TH01 STR locus. Although not one of the longest loci used for STR genotyping, it was chosen as a good compromise given the target length limitations on qPCR efficiency with TaqMan detection. The shorter target (nuCSF, 67 bp) was designed in the upstream flanking region of the CSF1PO STR locus. In addition to these human nuclear targets, the assay includes an internal PCR control target sequence to allow for an assessment of PCR inhibition. The assay was rigorously tested on samples with varying amounts of degradation, and the ratio of nuCSF:nuTH01 quantifications was shown to provide a good estimation of the degree of degradation present in a sample. This estimate, along with the internal control for PCR inhibition, provides a valuable tool for post-extraction sample assessment.     

A duplex real-time qPCR assay for the quantification of human nuclear and mitochondrial DNA in forensic samples: implications for quantifying DNA in degraded samples

A duplex real-time qPCR assay was developed for quantifying human nuclear and mitochondrial DNA in forensic samples. The nuclear portion of the assay utilized amplification of a approximately 170-190 bp target sequence that spans the repeat region of the TH01 STR locus, and the mitochondrial portion of the assay utilized amplification of a 69 bp target sequence in the ND1 region. Validation studies, performed on an ABI 7000 SDS instrument using TaqMan detection, demonstrated that both portions of the duplex assay provide suitable quantification sensitivity and precision down to 10-15 copies of each genome of interest and that neither portion shows cross-reactivity to commonly encountered non-human genomes. As part of the validation studies, a series of DNase-degraded samples were quantified using three different methods: the duplex nuclear-mitochondrial qPCR assay, the ABI Quantifiler Human DNA Quantification Kit qPCR assay, which amplifies and detects a 62 bp nuclear target sequence, and slot blot hybridization. For non-degraded and moderately degraded samples in the series, all three methods were suitably accurate for quantifying nuclear DNA to achieve successful STR amplifications to yield complete profiles using the ABI AmpFlSTR Identifiler kit. However, for highly degraded samples, the duplex qPCR assay provided better estimates of nuclear template for STR amplification than did either the commercial qPCR assay, which overestimated the quantity of STR-sized DNA fragments, leading to an increased proportion of undetected alleles at the larger STR loci, or slot blot hybridization, which underestimated the quantity of nuclear DNA, leading to an increased proportion of STR amplification artifacts due to amplification of excess template.     

Speaking the Unspeakable,Naming the Unnameable: The Royal Commission into Institutional Responses to Child Sexual Abuse

ABSTRACT

The establishment of the Royal Commission into Institutional Responses to Child Sexual Abuse followed years of lobbying by survivor groups, damning findings from previous inquiries, and increasing societal recognition of the often lifelong and intergenerational damage caused by child sexual abuse. Through extensive media coverage, the Royal Commission brought into public view the reality that the sexual abuse of children was widespread, and its recommendations are prompting organisational, policy, and legislative reform. This article explores the background to the Royal Commission, situating it within the history of previous inquiries and growing community outrage at the failure of institutions to adequately protect children and respond appropriately when abuse occurs. The article explores the ways in which the Royal Commission, more so than previous inquiries, brought child sexual abuse into public discourse. It also serves as an introduction to this special issue of the Journal of Australian Studies, which illustrates how the Royal Commission has fostered new scholarship across a range of disciplines as researchers engage with complex issues related to institutional child sexual abuse, its history, causes, impacts, and the important role of inquiries in confronting it.     

Corrosion behaviour of four handguns in aqueous environments: Corrosion product characterization and effects on estimating the time since deposition

When a firearm has been disposed of in a body of water and becomes corroded, its appearance is altered and determining a time-since-immersion may be of import to the investigation. Therefore, in this study, the corrosion and mass loss of four handgun slides over a period of 180 days were examined. Solid-state characterization of the metals and their corrosion products via SEM/EDX and powder X-ray Diffraction (pXRD) was performed. The pXRDs were analyzed against the NIST Powder Diffraction Database to determine the crystalline phases. Filings from the SS416 standard, Llama and Ruger handgun slide predominantly consisted of iron alloys. After 180-days in solution, pXRD indicated that the adherent corrosion products consisted of 1) γ-FeOOH and 2) iron oxide (Fe₃O₄ or Fe₂O₃). Additionally, pXRD analysis indicated that the adherent corrosion products of the SS416 standard also consisted of CrO₃. Metal filings from the Raven and Jennings handgun slides were a mixture of iron–nickel–zinc and EDX and pXRD analyses of the corrosion products, when submersed in deionized water, indicated that the products consisted of: 1) γ-FeOOH, 2) iron oxide (Fe₃O₄ or Fe₂O₃), and 3) ZnFe₂O₄ or ZnO; where the Jennings adherent rust contained ZnFe₂O₄ and the Raven adherent rust contained ZnO. Further, pXRD of the corrosion products from these alloys, when submersed in 25 PSU (Practical Salinity Unit) solution, indicated that the products consisted of: 1) ZnO, 2) Zn(OH)₂, 3) α-Ni(OH)₂, and 4) NaCl.The data thus indicated that both metal composition and the presence of chloride ions had significant impacts on rates and products of corrosion and suggest that the presence of Cl^? changes not only the rate of corrosion, but also the corroding species itself. While mechanisms and rates of the chloride driven corrosion processes offer explanations as to the different oxides and hydroxides observed between immersion conditions, they do not offer an explanation for the differences observed between handguns. Therefore, utilizing a general approach where surface area coverage of corrosion products is the sole consideration is not sufficient to determine time-since-immersion. Attempts to determine a time-since-immersion would require a priori knowledge of the mechanism of corrosion for a given metal mixture within a specified environment. The results described herein give indications as to the possible corrosion mechanism driving the process in high and low Cl^? environments and show the necessity of including the metal composition, rust composition and ion concentration in any models that attempt to elucidate the time-since-immersion of handguns for forensic applications.     

Measuring motivation to change in offenders

Abstract

Measuring motivation to change in offender populations is important both for selection into treatment programmes and for assessing progress in therapy. Two studies are reported in this paper, both looking at the psychometric properties of questionnaires designed to measure stage of change in therapy. The samples used were patients detained in special hospitals under the Mental Health Act (1983) classification of psychopathic disorder. The first study provides norms for this group on the stages of change in psychotherapy questionnaire, plus some additional information on its relationship with self-esteem and self-efficacy measures. The second study looked at a brief version of the stages of change questionnaire, concluding that its psychometric properties were such that further use was contra-indicated.     

Attachment-based practice with adults: understanding strategies and promoting positive change. A new practice model and interactive resource for assessment,intervention and supervision

Abstract

The purpose of this study was to test whether attachment styles change over the course of a sex offender-specific treatment programme for incarcerated adult male sex offenders. To measure attachment styles, 44 male sex offenders (treatment n = 26, waitlist n = 18) completed the Relationship Scales Questionnaire (RSQ) and the Adult Attachment Scale (AAS). The results indicated that treatment participants showed significant decreases in levels of anxious attachment measures from pre- to post-test. Furthermore, the results from the RSQ 2-factor showed that participants in the treatment group demonstrated a significant decrease in avoidant attachment levels at post-test compared to the waitlist group. The results from the AAS showed that participants in the treatment group demonstrated a significant decrease in dependent attachment levels at post-test compared to the waitlist group. Implications of results are discussed.     

Faculty Entrepreneurs and Research Productivity

In this paper, we analyze the research productivity of faculty entrepreneurs at 15 research institutes using a novel database combining faculty characteristics, licensing information, and journal publication records. We address two related research questions. First, are faculty entrepreneurs more productive researchers (“star scientists”) compared to their colleagues? Second, does the productivity of faculty entrepreneurs change after they found a firm? We find that faculty entrepreneurs in general are more productive researchers than control groups. We use multiple performance criteria in our analysis: differences in mean publication rate, skewness of publication rate, and impact of publications (journal citation rate). These findings bring together previous work on star scientists by Zucker, Darby, and Brewer [Zucker, L. G., Darby M. R., &; Brewer M. B. (1998). The American Economic Review, 88, 290–306.] and tacit knowledge among university entrepreneurs by Shane [Shane, S. (2002). Management Science, 48, 122–137.] and Lowe [Lowe, R. A. (2001). In G. Libecap (Ed.) Entrepreneurial Inputs and Outcomes. Amsterdam: JAI Press, Lowe, R.A. (2006). Journal of Technology Transfer, 31(4), 412–429]. Finally, we find that faculty entrepreneurs’ productivity not only is greater than their peers but also does not decrease following the formation of a firm.
