Trade-Offs Between Agricultural and Chemical Policy

In modern U.S. agriculture there are numerous tradeoffs between agricultural and chemical policies. Chemicals are major inputs in agricultural production processes (for both crops and livestock). Agricultural chemicals, however, have negative environmental side effects that are not always considered by users (Benbrook 1988). Agricultural policies primarily are designed to stabilize commodity prices and enhance farm income, which in turn changes production levels, provides incentives for different intensities of factor use, and influences the loading of chemicals. In turn, chemical policies involving taxes, use restrictions, and registration requirements change the availability and prices of chemical inputs, alter agricultural production and cost levels, and affect agricultural income

Mental health consultations in a prison population: a descriptive study

BACKGROUND: The psychiatric morbidity among prison inmates is substantially higher than in the general population. We do, however, have insufficient knowledge about the extent of psychiatric treatment provided in our prisons. The aim of the present study was to give a comprehensive description of all non-pharmacological interventions provided by the psychiatric health services to a stratified sample of prison inmates. METHODS: Six medium/large prisons (n = 928) representing 1/3 of the Norwegian prison population and with female and preventive detention inmates over-sampled, were investigated cross-sectionally. All non-pharmacological psychiatric interventions, excluding pure correctional programs, were recorded. Those receiving interventions were investigated further and compared to the remaining prison population. RESULTS: A total of 230 of the 928 inmates (25 %) had some form of psychiatric intervention: 184 (20 %) were in individual psychotherapy, in addition 40 (4 %) received ad hoc interventions during the registration week. Group therapy was infrequent (1 %). The psychotherapies were most often of a supportive (62 %) or behavioural-cognitive (26 %) nature. Dynamic, insight-oriented psychotherapies were infrequent (8 %). Concurrent psychopharmacological treatment was prevalent (52 %). Gender and age did not correlate with psychiatric interventions, whereas prisoner category (remanded, sentenced, or preventive detention) did (p < 0.001). Most inmates had a number of defined problem areas, with substance use, depression, anxiety, and personality disorders most prevalent. Three percent of all inmates were treated for a psychotic disorder. Remand prisoners averaged 14 sessions per week per 100 inmates, while sentenced inmates and those on preventive detention averaged 22 and 25 sessions per week per 100 inmates, respectively. Five out of six psychiatric health services estimated the inmates' psychiatric therapy needs as adequately met, both overall and in the majority of individual cases. CONCLUSION: Our results pertain only to prisons with adequate primary and mental health services and effective diversion from prison of individuals with serious mental disorders. Given these important limitations, we do propose that the service estimates found may serve as a rough guideline to the minimum number of sessions a prison's psychiatric health services should be able to fulfil in order to serve the inmates psychiatric needs. The results rely on the specialist services' own estimates only. Future studies should take other important informants, including the inmates themselves, into consideration

The utility of the Historical Clinical Risk -20 Scale as a predictor of outcomes in decisions to transfer patients from high to lower levels of security-A UK perspective

<p>Abstract</p> <p>Background</p> <p>Structured Professional Judgment (SPJ) approaches to violence risk assessment are increasingly being adopted into clinical practice in international forensic settings. The aim of this study was to examine the predictive validity of the Historical Clinical Risk -20 (HCR-20) violence risk assessment scale for outcome following transfers from high to medium security in a United Kingdom setting.</p> <p>Methods</p> <p>The sample was predominately male and mentally ill and the majority of cases were detained under the criminal section of the Mental Health Act (1986). The HCR-20 was rated based on detailed case file information on 72 cases transferred from high to medium security. Outcomes were examined, independent of risk score, and cases were classed as "success or failure" based on established criteria.</p> <p>Results</p> <p>The mean length of follow up was 6 years. The total HCR-20 score was a robust predictor of failure at lower levels of security and return to high security. The Clinical and Risk management items contributed most to predictive accuracy.</p> <p>Conclusions</p> <p>Although the HCR-20 was designed as a violence risk prediction tool our findings suggest it has potential utility in decisions to transfer patients from high to lower levels of security.</p

La renovación de la palabra en el bicentenario de la Argentina : los colores de la mirada lingüística

El libro reúne trabajos en los que se exponen resultados de investigaciones presentadas por investigadores de Argentina, Chile, Brasil, España, Italia y Alemania en el XII Congreso de la Sociedad Argentina de Lingüística (SAL), Bicentenario: la renovación de la palabra, realizado en Mendoza, Argentina, entre el 6 y el 9 de abril de 2010. Las temáticas abordadas en los 167 capítulos muestran las grandes líneas de investigación que se desarrollan fundamentalmente en nuestro país, pero también en los otros países mencionados arriba, y señalan además las áreas que recién se inician, con poca tradición en nuestro país y que deberían fomentarse. Los trabajos aquí publicados se enmarcan dentro de las siguientes disciplinas y/o campos de investigación: Fonología, Sintaxis, Semántica y Pragmática, Lingüística Cognitiva, Análisis del Discurso, Psicolingüística, Adquisición de la Lengua, Sociolingüística y Dialectología, Didáctica de la lengua, Lingüística Aplicada, Lingüística Computacional, Historia de la Lengua y la Lingüística, Lenguas Aborígenes, Filosofía del Lenguaje, Lexicología y Terminología

Preventing Suicide in Detention and Correctional Facilities

This essay describes and critiques suicide-prevention strategies in prison, including the extent to which screening and prevention programs are used in the United States. The epidemiology of suicide and suicide attempts in both jails and prisons is reviewed, with discussions of differences in suicide risk by demographic factors, individual risk and suicide protective factors, and contextual factors. A cross-section of legal cases leading to the establishment of a legal basis for suicide prevention in US correctional facilities is provided, followed by an overview of current national standards and best practice guidelines for preventing inmate suicides. The essential components of correctional suicide-prevention strategies are described and critiqued, including core values at the center of these strategies, aspects of most effective systems management, and evidenced-based clinical care. Finally, special considerations for different types of confinement settings are described.</p

Einfluß geringer Silberkonzentrationen auf einige lebende Organismen der evolutionären Reihe

Untersucht wurde die sanitär-toxikologische Wirkung von Elektrlytsilberlösungen in Wasser auf Hydrobionten und den Organismus von Warmblütern in akuten, subakuten und chronischen Versuchen. Für die Algen (Sc. quadricauda), Wasserflöhe (Daphnia magna), Fische (Guppy), Mäuse, Ratten und Kaninchen waren Silberkonzentrationen im Bereich von 5,0 - 4,0 bis 0,5 - 0,4 mg/l aktiv. Für die Hydrobionten ist eine Konzentration von 0,05 mg/l toxisch, die sich aber nicht auf Warmblüter auswirkt. Unter maritimen und sonstigen Bedingungen, wo zur Versorgung Wasser verwendet wird, das mit Silberionen konserviert wurde, sollte man den Silbergehalt im Wasser auf 0,05 mg/l begrenzen, was ungefähr einer gerade noch inaktiven Dosis an Konservierungsmittel (0,0025 mg pro 1 kg Lebendgewicht) entspricht
