The entrepreneurial puzzle: explaining the gender gap   总被引:1,自引:0,他引:1  
We document the substantial gender gap that exists among university scientists with regard to entrepreneurial activity using a variety of measures and explore factors leading to the disparity. We focus particularly on the biomedical sciences. The contextual explanation that women are under-represented in the types of positions from which faculty typically launch entrepreneurial activity is the most obvious. But the data suggest that for the biomedical sciences context is not sufficient in explaining the entrepreneurial gap. We look elsewhere to factors affecting supply and factors affecting demand. The former include gender differences in attitudes towards risk, competition, “selling” of “science,” type of research and geographic location. The latter include the role of networks, preferences of venture capitalists and “gender discounting.” We explore the associated hypotheses. We provide few tests and conclude that the research agenda is wide open and interesting.

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

The garment and textile factories and assembly plants in the Central American free trade zones, or maquila industry, have given rise to new actors on the labour scene, as women's organisations and local monitoring groups now work alongside the traditional trade union sector. Furthermore, some of these new organisations are linked to networks based elsewhere, mainly in the USA and Europe, and are actively involved in transnational campaigns to improve working conditions in the maquila. To date, attempts between trade unions and these new labour actors to collaborate have been disappointing and often characterised by conflict. Challenging the idea that trade unions and NGOs are in competition for the same limited ‘space’, by looking at the relations between trade unions and women's organisations, this paper asks whether such conflicts are inevitable, and suggests ways in which the two kinds of organisation could work together to improve the conditions of workers in Central America.  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
