Repairing the rupture : restorative justice and the rehabilitation of offenders

Restorative justice is a social justice movement that aims to deal with consequences of crime through repairing and restoring relationships of three key stakeholders: victims, offenders, and communities. Unfortunately, it is often unclear where offender rehabilitation fits within the constructs of repair and reintegration that drive this justice paradigm. An analysis of the relationship between restorative justice theory and offender rehabilitation principles reveals tensions between the two normative frameworks and a lack of appreciation that correctional treatment programs have a legitimate role alongside restorative practices. First, we outline the basic tenets of the Risk–Need–Responsivity Model and the Good Lives Model in order to provide a brief overview of two recent models of offender rehabilitation. We then consider the claims made by restorative justice proponents about correctional rehabilitation programs and their role in the criminal justice system. We conclude that restorative justice and rehabilitation models are distinct, although overlapping, normative frameworks and have different domains of application in the criminal justice system, and that it is a mistake to attempt to blend them in any robust sense.

Tightening eligibility for bail for persons on supervision orders in Victoria: repairing a broken system?

Victoria Nourse has observed that political debates about crime legislation are predictable and invariably one-sided because ‘no-one is “for” crime.’1 This certainly appears to be the case with regard to recent proposed changes to the Bail Act 1977 (‘the Act’) by the government of Victoria. The reforms were triggered by the case of Sean Price, an offender with a history of mental disorder, serious offending and lengthy incarceration who was on bail and subject to a supervision order when he murdered Masa Vukotic, raped another woman and assaulted a third person in March 2015. The Premier of Victoria, Daniel Andrews, stated that a bail system that allowed Price to be free and unmonitored was failing the community and pledged to repair ‘a system that is broken.’

A field model for repairing 3D shapes

This paper proposes a field model for repairing 3D shapes constructed from multi-view RGB data. Specifically, we represent a 3D shape in a Markov random field (MRF) in which the geometric information is encoded by random binary variables and the appearance information is retrieved from a set of RGB images captured at multiple viewpoints. The local priors in the MRF model capture the local structures of object shapes and are learnt from 3D shape templates using a convolutional deep belief network. Repairing a 3D shape is formulated as the maximum a posteriori (MAP) estimation in the corresponding MRF. Variational mean field approximation technique is adopted for the MAP estimation. The proposed method was evaluated on both artificial data and real data obtained from reconstruction of practical scenes. Experimental results have shown the robustness and efficiency of the proposed method in repairing noisy and incomplete 3D shapes.

Exercise and skeletal muscle gene expression

1. Skeletal muscle is a complex and heterogenous tissue capable of remarkable adaptation in response to exercise training. The role of gene transcription, as an initial target to control protein synthesis, is poorly understood.
2. Mature myofibres contain several hundred nuclei, all of which maintain transcriptional competency, although the localized responsiveness of nuclei is not well known. Myofibres are capable of hypertrophy. These processes require the activation and myogenic differentiation of mononuclear satellite cells that fuse with the enlarging or repairing myofibre.
3. A single bout of exercise in human subjects is capable of activating the expression of many diverse groups of genes.
4. The impact of repeated exercise bouts, typical of exercise training, on gene expression has yet to receive systematic investigation.
5. The molecular programme elicited by resistance exercise and endurance exercise differs markedly. Muscular hypertrophy following resistance exercise is dependent on the activation of satellite cells and their subsequent myogenic maturation. Endurance exercise requires the simultaneous activation of mitochondrial and nuclear genes to enable mitochondrial biogenesis.
6. Future analysis of the regulation of genes by exercise may combine high-throughput technologies, such as gene-chips, enabling the rapid detection and analysis of changes in the expression of many thousands of genes.

Vietnamese-born health professionals : negotiating work and life in rural Australia

Introduction: Australia is a culturally diverse nation due to migrants from a wide variety of countries creating a multicultural society. The health professions are highly valued by the younger generation of overseas-born migrants who have acculturated into Australian society; many have chosen health care as their profession in Australia. However, most migrants settle in metropolitan areas and young health professionals may find working in rural or remote Australia culturally and professionally highly challenging. The present study of migrant health professionals examined the life experiences and acculturation strategies of Vietnamese-born health professionals working and living in rural Australia. Objectives: The two main study objectives were to: (1) examine aspects of the acculturation of overseas-born and Australian-trained health professionals in the Australian health discourse; and (2) identify key coping strategies used by them when in working in the rural context.

Methods: Six overseas-born, Australian-trained health professionals were invited to participate in this qualitative study using a snowball sampling technique. The participants were all born in Vietnam and had experienced working in rural Australia. They included three medical doctors, a dentist, a physiotherapist and a nurse. The interviews were recorded and four participants also provided additional written responses to some of the open-ended interview questions. The interview data were transcribed and later coded for thematic analysis. Topics and themes that emerged focused on the issues and strategies of acculturation to the rural health context.

Results: The study showed that the acculturation process was affected by the participants’ views about and attitudes towards working in an Australian rural context. The study identified these essential strategies used by the participants in adapting to a new workplace: collaborating, distancing, adjusting, repairing, and accommodating.

Conclusion: The study provides insights into the lives of these health professionals in a rural context, and particularly their experience of cultural shock and the coping strategies they may use. A need is identified for a larger study to inform recruitment and retention of these health professionals to rural Australia, and to assist universities to prepare such students and their clinical supervisors for rural placements.

Fabricating and characterising silk powder for biomedical and sorption applications

This research developed a milling technology for ultrafine silk particles and designed novel biocompatible and biodegradable silk composites for repairing hard tissue defects. It also demonstrated high and rapid reversible ion binding properties of silk particles and thereby opened up their application opportunities as advanced green sorbents.

Preliminary results of the application of a silk fibroin scaffold to otology

The surgical treatment to repair chronic tympanic membrane perforations is myringoplasty. Although multiple autologous grafts, allografts, and synthetic graft materials have been used over the years, no single graft material is superior for repairing all perforation types. Recently, the remarkable properties of silk fibroin protein have been studied, with biomedical and tissue engineering applications in mind, across a number of medical and surgical disciplines. The present study examines the use of silk fibroin for its potential suitability as an alternative graft in myringoplasty surgery by investigating the growth and proliferation of human tympanic membrane keratinocytes on a silk fibroin scaffold in vitro. Light microscopy, immunofluorescent staining, and confocal imaging all reveal promising preliminary results. The biocompatibility, transparency, stability, high tensile strength, and biodegradability of fibroin make this biomaterial an attractive option to study for this utility.

X4 and R5 HIV-1 have distinct post-entry requirements for uracil DNA glycosylase during infection of primary cells

It has been assumed that R5 and X4 HIV utilize similar strategies to support viral cDNA synthesis post viral entry. In this study, we provide evidence to show that R5 and X4 HIV have distinct requirements for host cell uracil DNA glycosylase (UNG2) during the early stage of infection. UNG2 has been previously implicated in HIV infection, but its precise role remains controversial. In this study we show that, although UNG2 is highly expressed in different cell lines, UNG2 levels are low in the natural host cells of HIV. Short interfering RNA knockdown of endogenous UNG2 in primary cells showed that UNG2 is required for R5 but not X4 HIV infection and that this requirement is bypassed when HIV enters the target cell via vesicular stomatitis virus envelope-glycoprotein-mediated endocytosis. We also show that short interfering RNA knockdown of UNG2 in virus-producing primary cells leads to defective R5 HIV virions that are unable to complete viral cDNA synthesis. Quantitative PCR analysis revealed that endogenous UNG2 levels are transiently up-regulated post HIV infection, and this increase in UNG2 mRNA is ∼10–20 times higher in R5 versus X4 HIV-infected cells. Our data show that both virion-associated UNG2 and HIV infection-induced UNG2 expression are critical for reverse transcription during R5 but not X4 HIV infection. More importantly, we have made the novel observation that R5 and X4 HIV have distinct host cell factor requirements and differential capacities to induce gene expression during the early stages of infection. These differences may result from activation of distinct signaling cascades and/or infection of divergent T-lymphocyte subpopulations.

TMI for urban resilience : measuring and mapping long-term climate change effects on soil moisture

The effect of climate change on the shallow expansive foundation conditions of resident dwellings is costing several hundred billion dollars worldwide. The design and costs of constructing or repairing residential footings is greatly influenced by the degree of ground movement, which is driven by the magnitude of change in soil moisture. The impacts of climate change on urban infrastructure are expected to include accelerated degradation of materials and foundations of buildings and facilities, increased ground movement, changes in ground water affecting the chemical structure of foundations, and fatigue of structures from extreme storm events. Previous research found that residential houses that were built less than five years ago have suffered major cracks and other damage caused by slab movement after record rainfall. The Thornthwaite Moisture Index (TMI) categorises climate on the basis of rainfall, temperature, potential evapotranspiration and the water holding capacity of the soil. Originally TMI was mainly used to map soil moisture conditions for agriculture but soon became a method to predict pavement and foundation changes. Few researchers have developed TMI maps for Australia, but generally, their accuracy is low or unknown, and their use is limited. The aims of this paper are: (1) To produce accurate maps of TMI for the state of Victoria for 100 years (1913 to 2012) in 20 year periods using long-term historical climatic data and advanced spatial statistics methods in GIS, and (2) Analyse the spatial and temporal changes of TMI in Victoria. Preliminary results suggest that a better understanding of climate change through long-term TMI mapping can assist urban planning and guide construction regulations towards the development of cities which are more resilient.

Improving performance of CFRP retrofitted RC members using rubber modified epoxy (ongoing research)

Although the method of external attachment of CFRP to the concrete members is the most effective and economical solution for strengthening and repairing concrete structure in the century, the bonding issue between CFRP and the hosting surface still a challenge for the structural engineers. Many solutions are proposed to overcome the early debonding failure in the strengthened members. This paper reports an ongoing experimental program for testing CFRP retrofitted RC beams and slabs. Fifteen RC beams of dimensions 150x250x2300mm and twelve two- way RC slabs of size 85x1670x1670mm will be strengthened using different types of epoxies, different configurations and variable number of layers of CFRP strips (MBrace-230). Rubber modified epoxy will be used for carbon fibre external attachment using wet lay-up method. Loading frame of 500 kN capacity will be used for beams testing. While for applying uniformly distributed load on the slabs a purpose built attachment will be used. The experimental results will report on the ultimate load, failure mode, mid-span deflection, strains readings in different locations and the ductility for both groups of strengthened beams and slabs. A mathematical model will be developed to predict the behavior of RC beams and two-way slabs.

Imagining Kyrgyzstan's nationhood and statehood: reactions to the 2010 Osh violence

This article explores the tensions inherent in how Kyrgyzstan's nationhood and statehood have been imagined and practised via an analysis of local reactions to the findings of the Kyrgyzstan Inquiry Commission's (KIC) investigation into the 2010 Osh violence and in particular the threat narrative that developed in opposition to the investigation. In the wake of the clashes that erupted in Osh in June 2010, a recurrent theme was calls from the international community for an independent investigation. Within Kyrgyzstan, however, some politicians argued that investigations violated the republic's sovereignty. Despite local reluctance, a number of investigations did subsequently take place. Yet the reports of the respective investigations did little to quell controversy, with the KIC report being strongly criticized and declared a threat to national security. The strength of feeling demonstrated by this reaction was indicative of long-standing and unresolved tensions in Kyrgyzstan between international and local imaginings of nationhood and statehood. The article concludes by arguing that nationhood and statehood need to be reimagined to focus on re-establishing state–society relations by both local and international actors in order for Kyrgyzstan to begin repairing the already fragile sociopolitical relationships that were grievously damaged by the violence and the subsequent investigations.

Effect of strain ageing on the mechanical properties of partially damaged structural mild steel

ABSTRACT
This paper addresses the strain ageing effects on the mechanical properties of the partially damaged structural mild steel. Since repairing partly damaged structures may not occur immediately, the strain ageing effect can significantly influence the structural behaviour. The changes due to this effect have not so far been considered in the civil engineering design guidelines. In order to investigate strain ageing effects, two-stage experimental tests are carried out on the mild-steel specimens. In the first stage, partial damage is made using quasi-static loading. During the second stage, the strength and ductility of the specimens are examined after 2 and 7 days ‘ageing’ at room temperature and the results are compared with the corresponding no-age samples. The microstructure of the specimens is examined using scanning electron microscopy (SEM). To illustrate the effect of strain ageing on the global behaviour of steel structures, a numerical example is provided in which strain ageing impacts on loading capacity and deflection of a steel beam. Finally, the stress–strain relation of partially damaged mild-steel material incorporating strain ageing effects is expressed by calibrating the parameters of Ramberg–Osgood model.
