The definitive version was published in Marine Chemistry 121 (2010): 206-214, doi:10.1016/j.marchem.2010.04.009.Precise measurements of the short lived radium isotopes 223Ra and 224Ra by means of the delayed
coincidence counting system (RaDeCC) rely on an efficiency calibration of this system using
Mn-fiber standards for which radium activities are exactly known. We prepared seventeen
different standards by placing Mn-fibers in seawater spiked with various amounts of 227Ac (with
223Ra in radioactive equilibrium), 228Th (in radioactive equilibrium with 232Th and 224Ra) and
226Ra. We tested for quantitative adsorption of 227Ac and 228Th on the Mn-fibers by: (1)
measuring 227Ac and 232Th in the residual solutions after preparing the Mn-fiber standards and
(2) monitoring their 223Ra and 224Ra activities over a period of ~100 days. In the residual
solutions, the activities of 227Ac and 232Th were < 1.0 % and < 5.3 %, respectively, of the
activities initially added to the Mn-fibers. Our results indicate that Milli-Q water washing of the
Mn-fibers is the major source of our observed losses of thorium. Measurements of 227Ac
standards over 1œ years indicate a significant decrease of measurable 223Ra with time prohibiting
the long-term use of 227Ac Mn-fiber standards. We found the 224Ra efficiency to be independent
of the range of 227Ac, 228Th and 226Ra activities on the Mn-fibers standards used. The efficiency
determination for 223Ra, however, may be biased in the case of relatively high 224Ra activities
due to insufficient correction of chance of coincidence. Thus we suggest using a single 227Ac
Mn-fiber standard for the efficiency determination for 223Ra.M. Charette and H. Dulaiova were supported by a grant from the National Science Foundation (OCE- 0751461)
Intégration et inclusion : interconnexions et oppositions dans deux domaines éducatifs au Québec
Plusieurs systĂšmes Ă©ducatifs dans le monde, comme câest le cas au QuĂ©bec, tendent vers lâadoption de politiques dâĂ©ducation inclusive qui visent Ă rĂ©pondre de façon
Ă©quitable aux besoins de tous les Ă©lĂšves. Alors que le paradigme dâĂ©ducation inclusive concernait initialement les Ă©lĂšves qui prĂ©sentaient des handicaps ou considĂ©rĂ©s comme ayant des besoins particuliers, il englobe maintenant dâautres sous-groupes dâĂ©lĂšves, dont les Ă©lĂšves minorisĂ©s sur les plans de la diversitĂ© ethnoculturelle, religieuse et linguistique. Cet article propose une lecture critique de lâĂ©volution du paradigme de lâĂ©ducation inclusive et du concept dâintĂ©gration dans deux domaines Ă©ducatifs au QuĂ©bec : celui de lâadaptation scolaire et celui qui concerne la diversitĂ© ethnoculturelle, religieuse et linguistique (ERL). Lâexploration du chemin parcouru dans les deux domaines Ă©ducatifs illustre lâancrage de lâĂ©volution des concepts dans les dĂ©bats sociaux, qui eux-mĂȘmes sâarticulent selon des courants politiques, des sensibilitĂ©s particuliĂšres de la sociĂ©tĂ©, et qui se reflĂštent dans les pratiques des milieux scolaires. La conclusion invite le milieu de la recherche et les autoritĂ©s Ă©ducatives Ă contribuer Ă la clarification des concepts et des paradigmes, en leur rappelant que ces derniers peuvent enfermer les individus et les groupes dans des rapports sociaux parfois teintĂ©s de dynamique de domination
Supportive housing and forensic patient outcomes
In Canada, Review Boards are mandated to evaluate individuals found Not Criminally Responsible on Account of Mental Disorder (NCRMD) on an annual basis and render 1 of 3 dispositions: (a) custody, (b) conditional discharge, or (c) absolute discharge. To promote social reintegration, conditional discharge can be ordered with the condition to live in supportive housing. However, NCRMD accused face great barriers to housing access as a result of the stigma associated with the forensic label. The goal of this study was to evaluate the role of housing in the clinical and criminal trajectories of forensic patients as they reintegrate into the community. Data for this study were extracted from a national study of individuals found NCRMD in Canada (Crocker, Nicholls, Seto, CÎté, et al., in press). The present study focuses on a random sample of NCRMD accused in the province of Québec, who were under a conditional discharge disposition during the study period (n = 837). Controlling for sociodemographic, clinical, and criminal variables, survival analysis showed that individuals placed in independent housing following a conditional discharge from the Review Board were 2.5 times more likely to commit a new offense, nearly 3 times more likely to commit an offense against a person, and 1.4 times more likely to be readmitted for psychiatric treatment compared with individuals residing in supportive housing. These results point to the influence housing can have on the trajectories of forensic patients, above and beyond a range of clinical, criminological, and sociodemographic factors
The use of risk and need factors in forensic mental health decision-making and the role of gender and index offense severity
Canadian legislation makes Review Boards (RBs) responsible for rendering dispositions for individuals found Not Criminally Responsible on account of Mental Disorder (NCRMD) after considering public safety, the mental condition of the accused, and his/her potential for community reintegration. We reviewed 6,743 RB hearings for 1,794 individuals found NCRMD in the three largest Canadian provinces to investigate whether items from two empirically supported risk assessment measures, the Historical Clinical Risk Managementâ20 and the Violence Risk Appraisal Guide, were considered. Less than half the items were included in expert reports or in RBs' reasons for dispositions, and consideration of these items differed according to gender and index offense severity of the accused. These items included evidenceâbased risk factors and/or legally specified criteria: mental health, treatment, and criminal history. These results illustrate the gap between research on risk factors and the integration of this evidence into practice. In particular, we recommend the implementation of structured measures to reduce the potential for clinicians to be unduly influenced by gender and offense severity
Factors associated with review board dispositions following re-hospitalization among discharged persons found not criminally responsible
In the Canadian forensic mental health system, a person found Not Criminally Responsible on
account of Mental Disorder (NCRMD) and given a conditional discharge returns to the
community while remaining under the jurisdiction of a provincial/territorial Review Board.
However, the individual can be re-hospitalized while on conditional discharge, for reasons such
as substance use, violation of conditions, or violence. We investigated whether being rehospitalized has an impact on the factors associated with the subsequent Review Board
disposition. Persons found NCRMD from the three largest Canadian provinces who were
conditionally discharged at least once during the observation period were included in the sample
(N=1,367). These individuals were involved in 2,920 disposition hearings; nearly one-third of
patients (30%) were re-hospitalized after having been conditionally discharged by the Review
Board. The factors examined included the scales of the Historical Clinical Risk Management-20
and salient behavior that occurred since the previous hearing, such as substance use or
violence. The greater presence of clinical items resulted in a greater likelihood of a hospital
detention decision at the next hearing. The effect was larger for the re-hospitalized group than
for the group who successfully remained in the community since the last hearing. The results
suggest that dynamic factors, specifically indicators of mental health, are heavily weighted by
the Review Boards, consistent with the literature on imminent risk and in line with the NCRMD
legislation
The national trajectory project of individuals found not criminally responsible on account of mental disorder in Canada. Part 1 : context and methods
The National Trajectory Project examined longitudinal data from a large sample of people found not criminally responsible on account of mental disorder (NCRMD) to assess the presence of provincial differences in the application of the law, to examine the characteristics of people with serious mental illness who come into conflict with the law and receive this verdict, and to investigate the trajectories of NCRMDâaccused people as they traverse the mental health and criminal justice systems. Our paper describes the rationale for the National Trajectory Project and the methods used to collect data in Quebec, Ontario, and British Columbia, the 3 most populous provinces in Canada and the 3 provinces with the most people found NCRMD.Les membres du Projet national des trajectoires ont examinĂ© les donnĂ©es longitudinales dâun

The National Trajectory Project of individuals found not criminally responsible on account of mental disorder in Canada. Part 3 : trajectories and outcomes through the forensic system
Objective : To examine the processing and Review Board (RB) disposition outcomes of people found not criminally responsible on account of mental disorder (NCRMD) across the 3 most populous provinces in Canada. Although the Criminal Code is federally legislated, criminal justice is administered by provinces and territories. It follows that a person with mental illness who comes into conflict with the law and subsequently comes under the management of a legally mandated RB may experience different trajectories across jurisdictions.
Method : The National Trajectory Project examined 1800 men and women found NCRMD in British Columbia (n = 222), Quebec (n = 1094), and Ontario (n = 484) between May 2000 and April 2005, followed until December 2008.
Results : We found significant interprovincial differences in the trajectories of people found NCRMD, including time detained in hospital and time under the supervision of an RB. The odds of being conditionally or absolutely discharged by the RB varied across provinces, even after number of past offences, diagnosis at verdict, and most severe index offence (all covariates decreased likelihood of discharge) were considered.
Conclusions : Considerable discrepancies in the application of NCRMD legislation and the processing of NCRMD cases through the forensic system across the provinces suggests that fair and equitable treatment under the law could be enhanced by increased national integration and collaboration.Objectif : Examiner les rĂ©sultats du processus et des dispositions de la Commission d'examen (CE) pour les personnes dĂ©clarĂ©es non criminellement responsables pour cause de troubles mentaux (NCRTM) dans les 3 provinces les plus populeuses du Canada. Le Code criminel relĂšve de la compĂ©tence du gouvernement fĂ©dĂ©ral, mais la justice pĂ©nale est administrĂ©e par les provinces et territoires. Il s'ensuit qu'une personne ayant un trouble mental qui a des dĂ©mĂȘlĂ©s avec la justice et qui est subsĂ©quemment placĂ©e sous la supervision d'une CE peut connaĂźtre diffĂ©rentes trajectoires dans diffĂ©rentes juridictions ou rĂ©gions ou provinces.
Méthode : Le Projet national des trajectoires a permis d'examiner 1800 hommes et femmes déclarés NCRTM en Colombie-Britannique (n = 222), au Québec (n = 1094) et en Ontario (n = 484) de mai 2000 à avril 2005, et de les suivre jusqu'en décembre 2008.
RĂ©sultats : Nous avons constatĂ© des diffĂ©rences interprovinciales significatives dans les trajectoires des personnes dĂ©clarĂ©es NCRTM, notamment le temps de dĂ©tention dans un hĂŽpital et le temps sous la supervision d'une CE. Les probabilitĂ©s d'une libĂ©ration conditionnelle ou absolue accordĂ©e par la CE variaient entre les provinces, mĂȘme aprĂšs examen du nombre d'infractions passĂ©es, du diagnostic au verdict, et des infractions rĂ©pertoriĂ©es les plus graves (toutes les covariables rĂ©duisaient la probabilitĂ© d'une libĂ©ration).
Conclusions : Les Ă©carts considĂ©rables dans l'application de la lĂ©gislation NCRTM et dans le traitement des cas NCRTM au sein du systĂšme psycho-olĂ©gal entre les provinces suggĂšrent qu'un traitement juste et Ă©quitable en vertu de la loi pourrait ĂȘtre amĂ©liorĂ© par une plus grande intĂ©gration et collaboration nationale
