Das Programm der derzeitigen Bundesregierung sieht eine Reform der Gerichtsbarkeit öffentlichen Rechts vor, derzufolge (neben der Einrichtung von Verwaltungsgerichten in den Ländern und eines Verwaltungsgerichtes erster Instanz auf Bundesebene) nach einer Entscheidung des VwGH auch noch der VfGH angerufen werden kann. Der folgende Beitrag befasst sich mit den Konsequenzen einer solchen Konstruktion für den Vollzug von Gemeinschaftsrecht. 相似文献

This article reviews the research on intensive case management (ICM) programs as a jail diversion intervention for people with a serious mental illness (SMI). The review includes two types of ICM programs: (a) general ICM programs that included an assessment of arrests and incarceration rates for people with an SMI and (b) ICM programs specifically implemented as a component of a jail diversion intervention for people with an SMI. Results indicate that general ICM programs (19) rarely led to reductions in jail or arrest rates over time, and these rates were similar to those found in standard mental health services. General ICM programs that included an integrated addiction treatment component (8) had mixed results but a trend toward reductions in rates of arrests and incarceration over time for individuals with an SMI and a co-occurring substance use disorder. Results were mixed for jail diversion interventions with an ICM program, but most ICM programs (8) led to significant reductions in arrests and incarcerations over time. Specific elements of effective ICM jail diversion programs are discussed. 相似文献

Female recidivists speak about their experience in drug court while engaging in appreciative inquiry
Fischer M Geiger B Hughes ME 《International journal of offender therapy and comparative criminology》2007,51(6):703-722
Eleven female drug-court participants looked at current and past experiences to assess their program and envision future program innovations. From these women's perspective, the strongest component of drug court was being surrounded by staff dedicated to their progress and recovery. Graduated supervision and accurate drug testing were appreciated rather than resented when the participants were not humiliated and were treated with respect. Wraparound services, resources, and referral; treatment facilities that accepted children; and individualized treatment plans and therapy with offenders who are ex-addicts, and preferably females, allowed for greater involvement and active participation in recovery. Progressing through three phases, acquiring skills, a job, and visitation rights to see their children or regaining custody, increased these women's sense of self-efficacy perception and confidence in their ability to lead a drug-free, meaningful life. Findings show the importance of qualitative criteria in evaluating drug-court participants' progress and the process of recovery. 相似文献

Jazz music and jazz musicians have often been linked for better or worse to the world of addictive substances. Many talented jazz musicians either had their careers sidetracked or prematurely ended due to their addiction to drugs and/or alcohol. The rigors of nightly performances, travel, and for many musicians a disapproving society exacted a toll that impacted the creativity of many artists of the genre. The fact that drug and alcohol use had a significant impact on the performance levels of numerous jazz musicians in the 1940's and 1950's has been much discussed, but more study of that impact is warranted. While recent research has provided new information regarding this challenging topic, there is still much to learn. Indeed, a number of questions for inquiry may be posed. Among those questions are the following: Was the work of these jazz artists truly inspired? Would their creative output have been enhanced had they not been addicted to substances? What was the impact of the addictive substances on their ability to function as creative artists and is there evidence to refute or verify that impact? Are there identifiable traits in certain artists that allowed them to be creative in spite of their addictions? This examination presents an evaluation of the evidence of the link between creativity and substance abuse especially as it relates to selected jazz artists during this time period and how they remained creative and actually prospered in their careers in spite of addictions to controlled substances. 相似文献

Last year's introduction of an exception to the Stark Regulations and a new Anti-Kickback safe harbor allows donors (mainly hospitals) to assist recipients (mainly physicians) with the establishment of electronic health records systems. This Article analyses the new regulations and makes the case that, among other negative effects, they will create an undesirable shift in physician referrals in the short term. 相似文献

Gender Differences in the Educational Expectations of Urban,Low-Income African American Youth: The Role of Parents and the School 总被引:2,自引:1,他引:1
This study examined how youths’ gender is related to the educational expectations of urban, low-income African American youth,
their parents, and their teachers. As predicted, African American boys (ages 9–16) reported lower expectations for future
educational attainment than did their female counterparts. Parents and teachers also reported lower expectations for African
American boys (ages 6–16) than for girls. These findings held even when controlling for academic achievement. Contrary to
predictions, the magnitude of the difference in expectations for males vs. females did not increase as a function of youths’
age. In keeping with our hypotheses, parental expectations fully mediated the relation between youths’ gender and youths’
expectations. Finally, certain school-based factors (i.e., positive teacher expectations and positive youth perceptions of
the school environment) appeared to protect youths’ expectations from the deleterious impact of low parental expectations.

A 67-year-old woman noticed a strange smell from the cellar of her house. When she followed the smell, she found her 64-year-old husband with the face and upper part of his body lying on the stove of the private sauna. He was dead when the emergency doctor arrived. The autopsy revealed upper gastrointestinal bleeding from mucosal lesions in the esophagus with an agonal fall on the sauna stove as the cause of death. In addition, there were signs of chronic alcohol and drug abuse. 相似文献

A 7-year-old boy was killed by his father by manual strangulation during a murder-suicide. After the killing of the son, the father showed typical "undoing" behaviour: He changed the boy's clothes and laid him down on the bed. Then he placed candles around his head, put pictures of the parents' wedding around him and a crucifix and a picture of the family into his hands. He broke off a rose in a vase next to the bed, lit the candles and took photographs of his dead son. Later he called his wife, threatened to kill the son and finally called the police to confess the murder and to announce his forthcoming suicide. 相似文献

Suspects in shooting investigations in Chicago are routinely transported in department vehicles and detained in department facilities prior to gunshot residue (GSR) evidence collection. The GSR test results are used to associate the suspect with primary exposure to GSR. The potential for these vehicles and facilities being sources of secondary GSR contamination needed to be determined. A total of 201 samples were collected from randomly selected vehicles and detention facilities. The sampling collected trace materials from surfaces that suspects' hands may contact during the arrest process. These samples were examined for the presence of GSR particles using scanning electron microscopy. Upon completion of the automated analysis, those particles that met an initial GSR screening criterion were relocated and reanalyzed. The locations where GSR particles were recovered allowed us to make recommendations to the Chicago Police Department with regard to transporting and detaining these suspects. The low number of GSR particles recovered suggests that the potential for secondary contamination, although present, is relatively low. 相似文献

Five 44 gallon drums labeled as glycidyl methacrylate were seized by the Australian Customs Service and the Australian Federal Police at Port Botany, Sydney, Australia, in December 2004. Each drum contained a white, semisolid substance that was initially suspected to be 3,4-methylenedioxymethylamphetamine (MDMA). Gas chromatography-mass spectroscopy (GC/MS) analysis demonstrated that the material was neither glycidyl methacrylate nor MDMA. Because intelligence sources employed by federal agents indicated that this material was in some way connected to MDMA production, suspicion fell on the various MDMA precursor chemicals. Using a number of techniques including proton nuclear magnetic resonance spectroscopy ((1)H NMR), carbon nuclear magnetic resonance spectroscopy ((13)C NMR), GC/MS, infrared spectroscopy, and total synthesis, the unknown substance was eventually identified as methyl 3-[3',4'(methylenedioxy)phenyl]-2-methyl glycidate. The substance was also subjected to a published hydrolysis and decarboxylation procedure and gave a high yield of the MDMA precursor chemical, 3,4-methylenedioxyphenyl-2-propanone, thereby establishing this material as a "precursor to a precursor." 相似文献
