A social justice perspective on strengths-based approaches: Exploring educators’ perceptions and practices

What does it mean to engage in strengths-based (SB) approaches from a social justice perspective? In this paper we explore the accounts of educators who work with youth experiencing social and educational barriers to describe what it might mean to engage in SB practices from a social justice perspective. Using data generated from interviews, we draw on educators’ perspectives and reported practices to inform our conceptual understanding of a SB social justice approach. We propose that a social justice perspective of SB educational work involves at least four interconnecting sets of practices: recognizing students-in-context, critically engaging strengths and positivity, nurturing democratic relations, and enacting creative and flexible pedagogies. We contend that these interrelated sets of practices are necessary for youth to engage more fully in schooling.Key words: Social justice; strengths, youth, students deemed to be ‘at risk’, educator perspectivesQue cela signifie-t-il de s'engager dans des approches basées sur les points forts du point de vue de la justice sociale ? Dans cet article, nous étudions les récits d'éducateurs qui travaillent avec des jeunes et qui se confrontent à des barrières sociales et éducatives, pour décrire ce que pourrait signifier de s'engager dans des pratiques basées sur les point forts dans une perspective de justice sociale. En utilisant les données générées à partir d'entrevues, nous nous appuyons sur les perspectives de ces éducateurs et faisons état des pratiques pour renseigner notre compréhension conceptuelle d'une approche basée sur les points forts du point de vue de la justice sociale. Nous proposons que dans une perspective de justice sociale tout travail éducatif basé sur les points forts implique au moins quatre ensembles de pratiques interconnectés : la reconnaissance des élèves en contexte, l'engagement critique du potentiel et de la positivité, le maintien de relations démocratiques, et la promulgation de pédagogies créatives et flexibles. Nous soutenons que ces ensembles interdépendants de pratiques sont nécessaires pour que les jeunes s'engagent pleinement dans leur scolarité.Mots-clés : La justice sociale, les points forts, les jeunes, les élèves considérés comme «à risque», les perspectives des éducateurs

The Clinical Utility of Personality Profiles of High-Risk Offenders in Rehabilitation

Personality disorders are common among high-risk offenders. These disorders may have relevance for their risk of offending, and they are likely to present barriers to their engagement in rehabilitation programmes. Co-morbidity between personality disorders - and the high frequency of clinical disorders in general - in offender samples complicate research on personality disorder in offender rehabilitation. One approach to understanding this heterogeneity is to use cluster analysis (CA). CA is an empirical strategy which is used to identify subgroups (clusters) of individuals who have similar scores on the variables used in the analysis. It has been used to empirically identify different patterns of personality and clinical psychopathology among incarcerated offenders. Two profiles frequently emerge in cluster analytic research on offender psychopathology profiles: an antisocial/narcissistic profile and a high-psychopathology profile. However, previous research has not empirically examined whether the identification of these profiles has clinical relevance for offender rehabilitation; that is, whether the profiles are simply descriptive, or whether they can provide useful information for the management and rehabilitation of offenders. In the current research, I used data collected from high risk offenders entering prison-based rehabilitation programmes to investigate the clinical utility of psychopathology clusters. Using a self-report measure of personality and clinical psychopathology - the Millon Clinical Multiaxial Inventory III - I identified three clusters: a low-psychopathology cluster (26% of the sample), a high-psychopathology cluster (35% of the sample), and an antisocial/narcissistic cluster (39% of the sample). The high-psychopathology and antisocial/narcissistic clusters in particular resembled high risk clusters found in previous research. To determine whether the three clusters had clinical relevance, I investigated cluster differences in criminal risk, treatment responsivity, and self-report predictive validity. I found evidence for cluster differences in criminal risk: men in the high-psychopathology and antisocial/narcissistic clusters had higher rates of criminal recidivism after release compared to men in the low-psychopathology cluster. However, I found that regardless of psychopathology, men in all three clusters made progress in treatment, and there was little evidence that clusters that reported more psychopathology were less engaged, or made less progress. In the final study I examined cluster differences in self-presentation style and the predictive validity of self-report. Results indicated that offenders who reported high levels of psychopathology had a more general tendency for negative self-presentation, and their self-report on risk-related measures was highly predictive of criminal recidivism. Combined, the results of this research show that cluster analysis of self-reported psychopathology can generate a parsimonious model of heterogeneity in offender samples. Importantly, the resulting clusters can also provide information for some of the most important tasks in offender management: assessment and treatment. The results suggest the highest risk offenders tend to report higher levels of psychopathology, and that offenders who report extensive psychopathology also have highly predictive risk-related self-report. Perhaps one of the most reassuring findings of the current research is that even offenders who report high levels of psychopathology appear to benefit from rehabilitation

Analysis of pooled genome sequences from Djallonke and Sahelian Sheep of Ghana reveals co-localisation of regions of reduced heterozygosity with candidate genes for disease resistance and adaptation to a tropical environment

Background: The Djallonke sheep is well adapted to harsh environmental conditions, and is relatively resistant to Haemonchosis and resilient to animal trypanosomiasis. The larger Sahelian sheep, which cohabit the same region, is less well adapted to these disease challenges. Haemonchosis and Trypanosomiasis collectively cost the worldwide animal industry billions of dollars in production losses annually. Results: Here, we separately sequenced and then pooled according to breed the genomes from five unrelated individuals from each of the Djallonke and Sahelian sheep breeds (sourced from Ghana), at greater than 22-fold combined coverage for each breed. A total of approximately 404 million (97%) and 343 million (97%) sequence reads from the Djallonke and Sahelian breeds respectively, were successfully mapped to the sheep reference genome Oar v3.1. We identified approximately 11.1 million and 10.9 million single nucleotide polymorphisms (SNPs) in the Djallonke and Sahelian breeds, with approximately 15 and 16% respectively of these not previously reported in sheep. Multiple regions of reduced heterozygosity were also found; 70 co-localised within genomic regions harbouring genes that mediate disease resistance, immune response and adaptation in sheep or cattle. Thirty- three of the regions of reduced heterozygosity co-localised with previously reported genes for resistance to haemonchosis and trypanosomiasis. Conclusions: Our analyses suggest that these regions of reduced heterozygosity may be signatures of selection for these economically important diseases

Billiards in a general domain with random reflections

We study stochastic billiards on general tables: a particle moves according to its constant velocity inside some domain ${\mathcal D} \subset {\mathbb R}^d$ until it hits the boundary and bounces randomly inside according to some reflection law. We assume that the boundary of the domain is locally Lipschitz and almost everywhere continuously differentiable. The angle of the outgoing velocity with the inner normal vector has a specified, absolutely continuous density. We construct the discrete time and the continuous time processes recording the sequence of hitting points on the boundary and the pair location/velocity. We mainly focus on the case of bounded domains. Then, we prove exponential ergodicity of these two Markov processes, we study their invariant distribution and their normal (Gaussian) fluctuations. Of particular interest is the case of the cosine reflection law: the stationary distributions for the two processes are uniform in this case, the discrete time chain is reversible though the continuous time process is quasi-reversible. Also in this case, we give a natural construction of a chord "picked at random" in ${\mathcal D}$, and we study the angle of intersection of the process with a $(d-1)$-dimensional manifold contained in ${\mathcal D}$.Comment: 50 pages, 10 figures; To appear in: Archive for Rational Mechanics and Analysis; corrected Theorem 2.8 (induced chords in nonconvex subdomains

Slope dynamics project report : Holderness Coast - Aldbrough, survey & monitoring, 2001-2013

This report is a published product of an ongoing study by the British Geological Survey (BGS) of the coastal change at Aldbrough on the Holderness coast, East Riding of Yorkshire, UK. The test site at Aldbrough has been selected as one of the BGS Landslide Observatories because it is representative of the high rates of coastal recession along this stretch of the east coast. The Aldbrough Landslide Observatory is operated under the BGS ‘Slope Dynamics’ task within the BGS’s ‘Landslide’ project of the ‘Shallow Geohazards and Risk’ team. As well as providing new insights with respect to the volumetric rates of recession and the near surface processes, it is a focus for the trialling of new surface and subsurface monitoring technologies. The establishment of the Aldbrough observatory and the initial research findings are reported in a series of reports in addition to this report. These are: Hobbs, P.R.N., Jones, L.D., & Kirkham, M.P.

Sulfonated Styrene-(ethylene-co-butylene)-styrene/Montmorillonite Clay Nanocomposites: Synthesis, Morphology, and Properties

Sulfonated styrene-(ethylene-butylene)-styrene triblock copolymer (SSEBS) was synthesized by reaction of acetyl sulfate with SEBS. SSESB-clay nanocomposites were then prepared from hydrophilic Na-montmorillonite (MT) and organically (quaternary amine) modified hydrophobic nanoclay (OMT) at very low loading. SEBS did not show improvement in properties with MT-based nanocomposites. On sulfonation (3 and 6 weight%) of SEBS, hydrophilic MT clay-based nanocomposites exhibited better mechanical, dynamic mechanical, and thermal properties, and also controlled water–methanol mixture uptake and permeation and AC resistance. Microstructure determined by X-ray diffraction, atomic force microscopy, and transmission electron microscopy due to better dispersion of MT nanoclay particles and interaction of MT with SSEBS matrix was responsible for this effect. The resulting nanocomposites have potential as proton transfer membranes for Fuel Cell applications

A New Faint Milky Way Satellite Discovered in the Pan-STARRS1 3π Survey

We present the discovery of a faint Milky Way satellite, Laevens 2/Triangulum II, found in the Panoramic Survey Telescope And Rapid Response System (Pan-STARRS 1) 3 pi imaging data and confirmed with follow-up wide-field photometry from the Large Binocular Cameras. The stellar system, with an absolute magnitude of M_V=-1.8 +/-0.5, a heliocentric distance of 30 +2/-2 kpc, and a half-mass radius of 34 +9/-8 pc, shows remarkable similarity to faint, nearby, small satellites such as Willman 1, Segue 1, Segue 2, and Bo\"otes II. The discovery of Laevens 2/Triangulum II further populates the region of parameter space for which the boundary between dwarf galaxies and globular clusters becomes tenuous. Follow-up spectroscopy will ultimately determine the nature of this new satellite, whose spatial location hints at a possible connection with the complex Triangulum-Andromeda stellar structures

Objective: Juvenile dermatomyositis (DM) is a heterogeneous systemic immune-mediated vasculopathy. This study was undertaken to 1) identify inflammation/endothelial dysfunction–related biomarker profiles reflecting disease severity at diagnosis, and 2) establish whether such biomarker profiles could be used for predicting the response to treatment in patients with juvenile DM. Methods: In total, 39 biomarkers related to activation of endothelial

The Alvarez impact theory of mass extinction; limits to its applicability and the „great expectations syndrome”

For the past three decades, the Alvarez impact theory of mass extinction, causally related to catastrophic meteorite impacts, has been recurrently applied to multiple extinction boundaries. However, these multidisciplinary research efforts across the globe have been largely unsuccessful to date, with one outstanding exception: the Cretaceous-Paleogene boundary. The unicausal impact scenario as a leading explanation, when applied to the complex fossil record, has resulted in force-fitting of data and interpretations ("great expectations syndrome". The misunderstandings can be grouped at three successive levels of the testing process, and involve the unreflective application of the impact paradigm: (i) factual misidentification, i.e., an erroneous or indefinite recognition of the extraterrestrial record in sedimentological, physical and geochemical contexts, (ii) correlative misinterpretation of the adequately documented impact signals due to their incorrect dating, and (iii) causal overestimation when the proved impact characteristics are doubtful as a sufficient trigger of a contemporaneous global cosmic catastrophe. Examples of uncritical belief in the simple cause-effect scenario for the Frasnian-Famennian, Permian-Triassic, and Triassic-Jurassic (and the Eifelian-Givetian and Paleocene-Eocene as well) global events include mostly item-1 pitfalls (factual misidentification), with Ir enrichments and shocked minerals frequently misidentified. Therefore, these mass extinctions are still at the first test level, and only the F-F extinction is potentially seen in the context of item-2, the interpretative step, because of the possible causative link with the Siljan Ring crater (53 km in diameter). The erratically recognized cratering signature is often marked by large timing and size uncertainties, and item-3, the advanced causal inference, is in fact limited to clustered impacts that clearly predate major mass extinctions. The multi-impact lag-time pattern is particularly clear in the Late Triassic, when the largest (100 km diameter) Manicouagan crater was possibly concurrent with the end-Carnian extinction (or with the late Norian tetrapod turnover on an alternative time scale). The relatively small crater sizes and cratonic (crystalline rock basement) setting of these two craters further suggest the strongly insufficient extraterrestrial trigger of worldwide environmental traumas. However, to discuss the kill potential of impact events in a more robust fashion, their location and timing, vulnerability factors, especially target geology and palaeogeography in the context of associated climate-active volatile fluxes, should to be rigorously assessed. The current lack of conclusive impact evidence synchronous with most mass extinctions may still be somewhat misleading due to the predicted large set of undiscovered craters, particularly in light of the obscured record of oceanic impact events
