BACKGROUND: Though information about involuntary psychiatric hospitalizations (IPH) is crucial for the planning of Israel's National Mental Health Care Policy, very few studies have been carried out to date on this subject. AIMS: To identify trends in first IPH to all inpatient psychiatric settings in Israel. METHOD: The sample included all admissions of adults (18 years and older) over the ten-year period, 1991-2000, according to the registration of such admissions in the National Psychiatric Case Registry. RESULTS: A 2.4-fold increase was found in first IPH over the decade studied. The typical profile of the involuntarily admitted patient was that of a native-born Jewish male, aged 18-24 or 65 and older, single, with less than 8 years of education, and with a diagnosis of schizophrenia or delusional psychosis. CONCLUSIONS: These findings suggest the need for improving the interfaces between hospital and community services, and for preparing specific guidelines to extend the use of involuntary ambulatory treatment orders. Further study is needed to explore the respective roles of involuntary inpatient and outpatient treatment.  相似文献

As is commonly the case in new areas of research, workplace bullying researchers and practitioners have struggled to establish a single agreed-upon definition of this phenomenon. As a consequence, there are numerous definitions of workplace bullying currently in use around the world to investigate this serious workplace issue, to educate the workforce about this form of harassment and to assess claims involving allegations of workplace bullying. Additionally, little is known about how employees and people in general define workplace bullying behaviour, and whether current researcher, practitioner and legal definitions coincide with lay definitions of bullying. To compare researcher, practitioner and legal definitions of workplace bullying with lay definitions, the content of definitions composed by adults from diverse personal and professional backgrounds (N=1095) was analysed. Results confirmed that components commonly used by researchers and practitioners, including the occurrence of harmful and negative workplace behaviours, were frequently cited by participants as central defining components of bullying behaviour. In addition, lay definitions often included themes of fairness and respect. The emergence of these themes has important consequences for organisations responding to, and attempting to prevent the occurrence of workplace bullying behaviour in that organisations in which bullying is tolerated may violate both local laws as well as their ethical responsibility to provide employees with a safe, professional and respectful workplace.  相似文献

Using an investigation of a technical policy issue, this paper demonstrates the utility of employing an issue networks approach to understanding the dynamics among those concerned about the threat of earthquakes to the province of British Columbia, Canada and the state of Washington, United States. Such an approach focuses on issue emergence in the early stages of agenda building. This research demonstrates how scientific and technical expertise, in the absence of political leadership, is an unrivaled source of presumptive rights leading to key actor status within a specialized policy community. A complementary finding is that career-related rationales provide the overwhelming motivation for issue network participation.  相似文献

This paper provides a non-technical, accessible introduction to various topics in the burgeoning literature on the economics of science and technology. This is an interdisciplinary literature, drawing on the work of scholars in the fields of economics, public policy, sociology and management. The aim of this paper is to foster a deeper appreciation of the economic importance of science and technology issues. We also hope to stimulate additional research on these topics.  相似文献

A fully validated, sensitive and specific method for the extraction and quantification of Δ9-tetrahydrocannabinol (THC) and 11-nor-9-carboxy-Δ9-THC (THC-COOH) and for the detection of 11-hydroxy-Δ9-THC (11-OH THC) in oral fluid, urine and whole blood is presented. Solid-phase extraction and liquid chromatography–mass spectrometry (LC–MS) technique were used, with electrospray ionization. Three ions were monitored for THC and THC-COOH and two for 11-OH THC. The compounds were quantified by selected ion recording of m/z 315.31, 329.18 and 343.16 for THC, 11-OH THC and THC-COOH, respectively, and m/z 318.27 and 346.26 for the deuterated internal standards, THC-d3 and THC-COOH-d3, respectively. The method proved to be precise for THC and THC-COOH both in terms of intra-day and inter-day analysis, with intra-day coefficients of variation (CV) less than 6.3, 6.6 and 6.5% for THC in saliva, urine and blood, respectively, and 6.8 and 7.7% for THC-COOH in urine and blood, respectively. Day-to-day CVs were less than 3.5, 4.9 and 11.3% for THC in saliva, urine and blood, respectively, and 6.2 and 6.4% for THC-COOH in urine and blood, respectively. Limits of detection (LOD) were 2 ng/mL for THC in oral fluid and 0.5 ng/mL for THC and THC-COOH and 20 ng/mL for 11-OH THC, in urine and blood. Calibration curves showed a linear relationship for THC and THC-COOH in all samples (r2 > 0.999) within the range investigated.The procedure presented here has high specificity, selectivity and sensitivity. It can be regarded as an alternative method to GC–MS for the confirmation of positive immunoassay test results, and can be used as a suitable analytical tool for the quantification of THC and THC-COOH in oral fluid, urine and/or blood samples.  相似文献
