An integrative approach to threat assessment and management: security and mental health response to a threatening client

Workplace violence threat assessment and management practices represent an interdisciplinary approach to the diversion of potentially dangerous employees and clients. This case study illustrates such an intervention in a complex situation involving a social service agency and its client. Following a curtailment of services and an arrest, the client developed an escalating homicidal anger toward the agency administrator. Once a Tarasoff warning was received, the agency contacted a security company who organized a threat assessment and management plan involving interdisciplinary collaboration. Information developed in the course of the assessment was presented to prosecutors, who facilitated the client's arrest and involuntary psychiatric commitment until he was judged to be no longer dangerous. This case ultimately involved an integration of the services of security, law enforcement, mental health professionals, prosecutors, the courts and the state mental health system in leading to a successful diversion of the client from a path of intended violence.     

The Alberta Mental Health Act 2010 and Revolving Door Syndrome: Control,Care, and Identity in Making up People

In this paper, I describe dividing practices in making up a specific medical‐legal category—the revolving door patient—to identify, label, and direct the actions of particular people living with mental illness. The revolving door patient was a category that had been spoken of for some time, but became a formal legal subject with the introduction of the Alberta Mental Health Act 2010 and Community Treatment Orders (CTOs). I demonstrate how a rationale of control over unpredictable and dangerous individuals was primary in creating this new category, and that the characterization of the revolving door patient required a disciplinary technology to reduce danger. I argue that the CTO is a medical‐legal technology that solves the problem of governing a subject in order to produce a patient that manages mental illness. I conclude by reflecting on how the narrative of the revolving door patient, and of mental illness more broadly, has implications for personal identity and tensions between care and control. Dans cet article, je décris comment des ‘pratiques divisées’ ont créé une catégorie spécifique médico‐légale ‐ le « revolving door patient » ‐ afin d'identifier, d’étiqueter et de contrôler les comportements de certains individus vivants avec une maladie mentale. Le «revolving door patient», une catégorie dont on avait parlé depuis un certain temps, est devenu un sujet juridique formel par l'introduction de la loi de la santé mentale de l'Alberta 2010 et de l'Ordre de Traitement Communautaire (OCT). Je démontre comment une logique de contrôle sur les individus imprévisibles et dangereux eu un rôle prépondérant lors de la création de cette catégorie et que la caractérisation du «revolving door patient», entant que telle, a nécessité une technologie disciplinaire pour réduire le danger social. Je soutiens que le OTC est une technologie médico‐légale qui résout le problème de contrôle d'un sujet en produisant un patient qui gère une maladie mentale. Je conclus en démontrant de quelle façon le «revolving door patient», et la maladie mentale en général, a des répercussions sur l'identité personnelle et produisent des tensions entre les soins et le contrôle.     

Suicide and suicide risk in lesbian, gay, bisexual, and transgender populations: review and recommendations

Despite strong indications of elevated risk of suicidal behavior in lesbian, gay, bisexual, and transgender people, limited attention has been given to research, interventions or suicide prevention programs targeting these populations. This article is a culmination of a three-year effort by an expert panel to address the need for better understanding of suicidal behavior and suicide risk in sexual minority populations, and stimulate the development of needed prevention strategies, interventions and policy changes. This article summarizes existing research findings, and makes recommendations for addressing knowledge gaps and applying current knowledge to relevant areas of suicide prevention practice.     

A Note on SERVQUAL Reliability and Validity in Information System Service Quality Measurement

Today's information system function includes a large service component. Recent research has examined the SERVQUAL instrument as a possible measure to assist managers and researchers in evaluating service quality. To further examine the appropriateness of the SERVQUAL measure, a large industry sample serves to verify the anticipated structure of the instrument. In addition, a high correlation with a common measure of user satisfaction indicates that the SERVQUAL metric may indeed represent accurate views of user perception. As such, the SERVQUAL instrument can serve as a useful indicator for information system managers attempting to identify areas of needed service improvement and to researchers seeking a success measure of information system services.     

The role of the minimum clinically important difference and its impact on designing a trial

The minimum clinically important difference (MCID) between treatments is recognized as a key concept in the design and interpretation of results from a clinical trial. Yet even assuming such a difference can be derived, it is not necessarily clear how it should be used. In this paper, we consider three possible roles for the MCID. They are: (1) using the MCID to determine the required sample size so that the trial has a pre-specified statistical power to conclude a significant treatment effect when the treatment effect is equal to the MCID; (2) requiring with high probability, the observed treatment effect in a trial, in addition to being statistically significant, to be at least as large as the MCID; (3) demonstrating via hypothesis testing that the effect of the new treatment is at least as large as the MCID. We will examine the implications of the three different possible roles of the MCID on sample size, expectations of a new treatment, and the chance for a successful trial. We also give our opinion on how the MCID should generally be used in the design and interpretation of results from a clinical trial.     

AN EVALUATION OF ORDER RELEASE MECHANISMS IN A JOB-SHOP ENVIRONMENT

Controlling the flow of material on the shop floor involves releasing and dispatching jobs to meet customer due-date requirements while attempting to keep operating costs low. This report presents an evaluation of five releasing mechanisms and four dispatching rules under various levels of aggregate due-date tightness, shop cost structure, and machine utilization using simulation. The performance criteria of total shop cost, jobs on shop floor, deviation from due dates, and job queue time are collected to demonstrate the interactive nature of releasing and dispatching on shop performance.     

Statistical considerations in a delayed‐start design to demonstrate disease modification effect in neurodegenerative disorders

There has been a paradigm shift in diagnostic conceptualization of Alzheimer's disease (AD) based on the current evidence suggesting that structure and biology changes start to occur before clinical symptoms emerge. Consequently, therapeutic drug development is also shifting to treat early AD patients using biomarkers for enrichment in clinical trials. A similar paradigm shift is occurring for Parkinson disease. In the absence of acceptable biomarkers that could be combined with a clinical endpoint to demonstrate a disease modification (DM) effect in neurodegenerative disorders, a delayed‐start design can be applied to demonstrate a lasting effect on the disease course. The delayed‐start design includes two treatment periods, where in period 1, patients are randomized to receive an active treatment or placebo, and in period 2, placebo patients are switched to the active treatment while patients in the active treatment arm will continue the same treatment. The hypothesis is that patients who start the active treatment later will fail to catch up to the treatment benefit achieved by patients who receive the active treatment in both periods. A usual analytical approach has sought to demonstrate the divergence of slope during period 1 and the parallelism of slopes during period 2 as the DM effect. However, due to heterogeneity in timing and the magnitude of maximal effect among patients, nonlinear response over time could be observed within the two treatment arms in both periods. We propose an approach to evaluate the DM effect with the linearity assumption for treatment differences, but not for each arm separately.     

SELF-SAMPLING: A UNIQUE AND EFFECTIVE MEASUREMENT TECHNIQUE IN HIGHER EDUCATION

Self-sampling, which is similar to work sampling, is a measurement technique where participants categorize their own activities. The ratio of observations in an activity category to the total observations provides an estimator of the population proportion of time spent on that category of activity. This paper summarizes how self-sampling works and describes an example involving business school faculty.
