A window on relationships: reflecting critically on a current restorative justice theory

Inherent in the task of theorising is a responsibility for ongoing critical reflection of the ideas presented (Steele, 2010). To that end, this article responds to the invitation extended by McCold and Wachtel to examine the conceptual theory of restorative justice they first presented in 2003 and which continues to be promoted globally. One particular aspect of their theory, the Social Discipline Window, is examined. Drawing on a qualitative, critical case study conducted in schools in Ontario, Canada, the article illustrates: (a) how unexamined theory can be problematic and promote practice that counters the principles of restorative justice; and (b) how people's lives can be impacted by power dynamics inherent in the theory presented (Woolford, 2009). In response, a revised Relationship Window is presented along with examples of how it can affect practice that is more consistently aligned with the philosophical foundations of restorative justice.

The significance of restorative justice in schools

Este artículo trata de abordar el uso dominante de los enfoques punitivos a los problemas de comportamiento en las escuelas, y se propone un enfoque de justicia restaurativa. En los Estados Unidos, y especialmente después de 1994, las políticas de tolerancia cero han transformado los problemas de control social en una crisis de graves proporciones. Estas políticas («tolerancia cero») parece que han servido, principalmente, para sólo marginalizar más a los chicos latinos y afroamericanos y para agravar, a largo plazo, los retos políticos, económicos y sociales del país. Sobre la base de las tradiciones de justicia restaurativa internacionales y la experiencia de los pueblos indígenas en los Estados Unidos, el objetivo de la justicia restaurativa es devolver a la víctima a la situación anterior al delito y reconstruir la relación del agresor tanto con el ofendido como con la comunidad. El artículo establece los principios que rigen un proceso de restauración, así como sus componentes esenciales.

DESCRIÇÃO E ANÁLISE DOS ELEMENTOS ESTRUTURAIS DOS CÍRCULOS RESTAURATIVOS E DOS FENÔMENOS DO CAMPO GRUPAL EM PROCESSOS ENVOLVENDO A JUSTIÇA RESTAURATIVA NO AMBIENTE ESCOLAR

A população e as comunidades escolares vêm pressionando e cobrando as autoridades dos Sistemas de Justiça e da Educação por uma intervenção coerente e efetiva na resolução de conflitos que se estabelecem no ambiente escolar, uma vez que o atual modelo de Justiça, o retributivo, não tem sanado a situação. A Justiça restaurativa surge então como uma nova maneira para enfrentar esse problema e uma de suas estratégias é o círculo restaurativo, caracterizado como um grupo para restauração das relações e dos conflitos. Esta pesquisa visa: descrever e analisar os elementos estruturais dos círculos restaurativos e os fenômenos do campo grupal em processos restaurativos realizados no ambiente escolar para intervir em situações de conflito. A amostra foi composta de cinco práticas restaurativas que envolveram pré-círculo, círculo e o pós-círculo mediados por um facilitador e dois co-facilitadores. O tratamento dos dados se deu a partir da análise dos elementos estruturais da justiça restaurativa (cerimônia de abertura e fechamento, bastão de fala, e processo decisório consensual), considerando tais elementos iguais ao setting de base psicanalítica, visto que neste caso especifico, tem como objetivo deixar claro aos participantes do grupo qual é a proposta de funcionamento do mesmo; e de uma análise de conteúdo organizada a partir de categorias pré-definidas, segundo conceitos psicanalíticos (resistência, acting/atuação e insight/elaboração). Os resultados mostraram que foram estabelecidos elementos estruturais (setting) favorável ao encontro dos participantes e que predominaram no campo aspectos positivos, o que resultou no bom reestabelecimento do convívio em todos os casos analisados. Os elementos estruturais estabelecidos para a realização do círculo restaurativo criaram um espaço seguro onde os participantes se ligaram de modo positivo, mesmo com a situação de conflito. Considera-se importante creditar a figura do facilitador (Psicólogo) parte da realização da resolução do conflito. Conclui-se que a função continente; o manejo e compreensão das resistências, actings e dos insights contribuíram para que o campo grupal configurasse em coesão ao invés da desintegração. Finalmente, cabe acrescentar que a experiência demonstrou que as crianças e adolescentes respondem muito bem quando são convidados a participar de um círculo restaurativo e ali aprendem a agir de acordo com os valores vivenciados como em um processo educativo.

Comparative analysis of strut-and-tie models using Smooth Evolutionary Structural Optimization

The strut-and-tie models are widely used in certain types of structural elements in reinforced concrete and in regions with complexity of the stress state, called regions D, where the distribution of deformations in the cross section is not linear. This paper introduces a numerical technique to determine the strut-and-tie models using a variant of the classical Evolutionary Structural Optimization, which is called Smooth Evolutionary Structural Optimization. The basic idea of this technique is to identify the numerical flow of stresses generated in the structure, setting out in more technical and rational members of strut-and-tie, and to quantify their value for future structural design. This paper presents an index performance based on the evolutionary topology optimization method for automatically generating optimal strut-and-tie models in reinforced concrete structures with stress constraints. In the proposed approach, the element with the lowest Von Mises stress is calculated for element removal, while a performance index is used to monitor the evolutionary optimization process. Thus, a comparative analysis of the strut-and-tie models for beams is proposed with the presentation of examples from the literature that demonstrates the efficiency of this formulation. © 2013 Elsevier Ltd.

Emotions, Crime and Justice: Exploring Durkheimian Themes

The process of ‘emotionalization’ of law and criminal justice has decisively changed criminological perspectives on the role of emotions in crime and justice during the last decade. ‘Reintegrative Shaming’ and Restorative Justice have been influential in re-shaping criminal justice around the globe, and the ‘return of emotions’ into criminological perspectives, theories and research is presently re-configuring notions of the ‘rational offender’ and criminal justice policies based on these. This paper seeks to carve out a distinctly sociological perspective on the link between emotions, crime and justice, and explores its potential through four ‘Durkheimian themes’.

Returning to the practices of our ancestors? Reconsidering Indigenous justice and the emergence of restorative practices

Restorative practices have often been considered both as emerging from the customs of Indigenous peoples, and ways of responding to crime that might be most suitable for Indigenous individuals and communities. This paper, which consists of two parts, will reconsider these claims from a critical perspective. The first part of the paper draws on my Ph.D. research on the emergence of restorative justice in Western criminal justice systems. It will argue that although many advocates of restorative justice uncritically and unproblematically accept that restorative practices emerged from the customs of Indigenous peoples, the relationship between Indigenous justice customs and the emergence of restorative justice is much more nuanced than proponents imply. The paper will examine, therefore, the legitimating rationalities associated with the diverse historical ‘truths’ obscured in advocates’ accounts of the role of Indigenous customs and the emergence of restorative justice. The second section draws on the findings of recent research undertaken at the Australian Institute of Criminology, and will present data on the numbers of Indigenous juveniles who participate in restorative conferences in each jurisdiction. These data will be used to elucidate the disparity between the rhetoric or ‘promise’ of restorative justice, and its apparent impact in relation to Indigenous juveniles. This paper will conclude with a consideration of the continued relevance of restorative justice for Indigenous young people in Australia.

Vulnerability and damage analysis of reinforced concrete framed buildings subjected to near field blast events

Terrorists usually target high occupancy iconic and public buildings using vehicle borne incendiary devices in order to claim a maximum number of lives and cause extensive damage to public property. While initial casualties are due to direct shock by the explosion, collapse of structural elements may extensively increase the total figure. Most of these buildings have been or are built without consideration of their vulnerability to such events. Therefore, the vulnerability and residual capacity assessment of buildings to deliberately exploded bombs is important to provide mitigation strategies to protect the buildings' occupants and the property. Explosive loads and their effects on a building have therefore attracted significant attention in the recent past. Comprehensive and economical design strategies must be developed for future construction. This research investigates the response and damage of reinforced concrete (RC) framed buildings together with their load bearing key structural components to a near field blast event. Finite element method (FEM) based analysis was used to investigate the structural framing system and components for global stability, followed by a rigorous analysis of key structural components for damage evaluation using the codes SAP2000 and LS DYNA respectively. The research involved four important areas in structural engineering. They are blast load determination, numerical modelling with FEM techniques, material performance under high strain rate and non-linear dynamic structural analysis. The response and damage of a RC framed building for different blast load scenarios were investigated. The blast influence region for a two dimensional RC frame was investigated for different load conditions and identified the critical region for each loading case. Two types of design methods are recommended for RC columns to provide superior residual capacities. They are RC columns detailing with multi-layer steel reinforcement cages and a composite columns including a central structural steel core. These are to provide post blast gravity load resisting capacity compared to typical RC column against a catastrophic collapse. Overall, this research broadens the current knowledge of blast and residual capacity analysis of RC framed structures and recommends methods to evaluate and mitigate blast impact on key elements of multi-storey buildings.

Moving forwards with the aim of going backwards fast : high performance rowing as a learning environment

Background and Purpose: - This paper focuses on the learning culture within the high performance levels of rowing. In doing so, we explore the case of an individual’s learning as he moves across athletic, coaching and administrative functions. This exploration draws on a cultural learning framework and complementary theorisings related to reflexivity. Method - This study makes use of an intellectually, morally and collaboratively challenging approach whereby one member of the research team was also the sole participant of this study. The participant’s careers as a high performance athlete, coach and administrator, coupled with his experience in conducting empirical research presented a rare opportunity to engage in collaborative research (involving degrees of insider and outsider status for each of the research team). We acknowledge that others have looked to combine roles of coach / athlete / administrator with that of researcher however few (if any) have attempted to combine them all in one project. Moreover, coupled with the approach to reflexivity adopted in this study and the authorship contributions we consider this scholarly direction uncommon. Data were comprised of recorded research conversations, a subsequently constructed learning narrative, reflections on the narrative, a stimulated reflective piece from the participant, and a final (re)construction of the participant’s story. Accordingly, data were integrated through an iterative process of thematic analysis. Results - The cultural (i.e., the ways things get done) and structural (e.g., the rules and regulations) properties of high performance rowing were found to shape both the opportunities to be present (e.g., secure a place in the crew) and to learn (e.g., learn the skills required to perform at an Olympic level). However, the individual’s personal properties were brought to bear on re-shaping the constraints such that many limitations could be overcome. In keeping with the theory of learning cultures, the culture of rowing was found to position individuals (a coxswain in this case) differentially. In a similar manner, a range of structural features was found to be important in shaping the cultural and personal elements in performance contexts. For example, the ‘field of play’ was found to be important as a structural feature (i.e., inability of coach to communicate with athletes) in shaping the cultural and personal elements of learning in competition (e.g., positioning the coxswain as an in-boat coach and trusted crewmate). Finally, the cultural and structural elements in rowing appeared to be activated by the participant’s personal elements, most notably his orientation towards quality performance. Conclusion - The participant in this study was found to be driven by the project that he cares about most and at each turn he has bent his understanding of his sport back on itself to see if he can find opportunities to learn and subsequently explore ways to improve performance. The story here emphasises the importance of learner agency, and this is an aspect that has often been missing in recent theorising about learning. In this study, we find an agent using his ‘personal emergent powers to activate the resources in the culture and structure of his sport in an attempt to improve performance. We conclude from this account that this particular high performance rowing culture is one that provided support but nonetheless encouraged those involved, to ‘figure things out’ for themselves – be it as athletes, coaches and/or administrators.

Unraveling the nature of electric field- and stress- induced structural transformations in soft PZT by a new powder poling technique

A `powder-poling' technique was developed to study electric field induced structural transformations in ferroelectrics exhibiting a morphotropic phase boundary (MPB). The technique was employed on soft PZT exhibiting a large longitudinal piezoelectric response (d(33) similar to 650 pCN(-1)). It was found that electric poling brings about a considerable degree of irreversible tetragonal to monoclinic transformation. The same transformation was achieved after subjecting the specimen to mechanical stress, which suggests an equivalence of stress and electric field with regard to the structural mechanism in MPB compositions. The electric field induced structural transformation was also found to be accompanied by a decrease in the spatial coherence of polarization.

Electric field induced short range to long range structural ordering and its influence on the Eu+3 photoluminescence in the lead-free ferroelectric Na1/2Bi1/2TiO3

Eu+3 was incorporated into the lattice of a lead-free ferroelectric Na1/2Bi1/2TiO3 (NBT) as per the nominal formula Na0.5Bi0.5-xEuxTiO3. This system was investigated with regard to the Eu+3 photoluminescence (PL) and structural behaviour as a function of composition and electric field. Electric field was found to irreversibly change the features in the PL spectra and also in the x-ray diffraction patterns below the critical composition x = 0.025. Detailed analysis revealed that below the critical composition, electric field irreversibly suppresses the structural heterogeneity inherent of the host matrix NBT and brings about a long range ferroelectric state with rhombohedral (R3c) distortion. It is shown that the structural disorder on the nano-scale opens a new channel for radiative transition which manifests as a new emission line branching off from the main D-5(0)-> F-7(0) line along with a concomitant change in the relative intensity of the other crystal field induced Stark lines with different J values. The study suggests that Eu+3 luminescence can be used to probe the relative degree of field induced structural ordering in relaxor ferroelectrics and also in high performance piezoelectric alloys where electric field couples very strongly with the lattice and structural degrees of freedom.

Light-matter Interactions in Semiconductors and Metals: From Nitride Optoelectronics to Quantum Plasmonics

This thesis puts forth a theory-directed approach coupled with spectroscopy aimed at the discovery and understanding of light-matter interactions in semiconductors and metals.

The first part of the thesis presents the discovery and development of Zn-IV nitride materials.The commercial prominence in the optoelectronics industry of tunable semiconductor alloy materials based on nitride semiconductor devices, specifically InGaN, motivates the search for earth-abundant alternatives for use in efficient, high-quality optoelectronic devices. II-IV-N2 compounds, which are closely related to the wurtzite-structured III-N semiconductors, have similar electronic and optical properties to InGaN namely direct band gaps, high quantum efficiencies and large optical absorption coefficients. The choice of different group II and group IV elements provides chemical diversity that can be exploited to tune the structural and electronic properties through the series of alloys. The first theoretical and experimental investigation of the ZnSnxGe1−xN2 series as a replacement for III-nitrides is discussed here.

The second half of the thesis shows ab−initio calculations for surface plasmons and plasmonic hot carrier dynamics. Surface plasmons, electromagnetic modes confined to the surface of a conductor-dielectric interface, have sparked renewed interest because of their quantum nature and their broad range of applications. The decay of surface plasmons is usually a detriment in the field of plasmonics, but the possibility to capture the energy normally lost to heat would open new opportunities in photon sensors, energy conversion devices and switching. A theoretical understanding of plasmon-driven hot carrier generation and relaxation dynamics in the ultrafast regime is presented here. Additionally calculations for plasmon-mediated upconversion as well as an energy-dependent transport model for these non-equilibrium carriers are shown.

Finally, this thesis gives an outlook on the potential of non-equilibrium phenomena in metals and semiconductors for future light-based technologies.
