With the aim of enabling students and teachers to work together in multinational groups in order to gain new perspectives on a specific topic being studied and so benefit from special learning and teaching conditions not available in a single institution, the European Commission funds international Intensive Programmes under the ambit of Erasmus mobility. An Intensive Programme culminates in a short programme of study, lasting from 10 continuous full days to six weeks, which brings together at one of the partner institutions students and teaching staff from higher education institutions of at least three countries who have spent the preceding semester studying the topic under consideration at their home institutions. The purpose of the present paper is to explore the nature of Erasmus Intensive Programmes and their value for law students by sharing the experience of London South Bank University's engagement in such a programme with four partner institutions from across the EU. The programme constitutes an option module for final year LLB students and LLM students on a relevant LLM programme. The paper considers the parameters within which such programmes operate, their aims and objectives and the extent to which such aims and objectives are made out. It is suggested that such programmes may fulfil a particularly useful function in enabling students on qualifying law degrees in the UK to enhance their employability by participating in an international collaborative project without the need to extend their degree length.  相似文献

The aim of this paper is to present the findings of a PhD research (Heinzl 2007, Unpublished PhD Thesis) conducted on the Universities of Applied Sciences in Austria. Four of the models that emerge from this research are: Generic Technology Transfer Model (Sect. 5.1); Idiosyncrasies Model for the Austrian Universities of Applied Sciences (Sect. 5.2); Idiosyncrasies-Technology Transfer Effects Model (Sect. 5.3); Idiosyncrasies-Technology Transfer Cumulated Effects Model (Sect. 5.3). The primary and secondary research methods employed for this study are: literature survey, focus groups, participant observation, and interviews. The findings of the research contribute to a conceptual design of a technology transfer system which aims to enhance the higher education institutions’ technology transfer performance.  相似文献

Five experiments tested the idea that instructing a witness to close their eyes during retrieval might increase retrieval success. In Experiment 1 participants watched a video, before a cued-recall test for which they were either instructed to close their eyes, or received no-instructions. Eye-closure led to an increase in correct cued-recall, with no increase in incorrect responses. Experiments 2-5 sought to test the generality of this effect over variations in study material (video or live interaction), test format (cued- or free-recall) and information modality (visual or auditory details recalled). Overall, eye-closure increased recall of both visual detail and auditory details, with no accompanying increase in recall of false details. Collectively, these data convincingly demonstrate the benefits of eye-closure as an aid to retrieval, and offer insight into why hypnosis, which usually involves eye-closure, may facilitate eyewitness recall.  相似文献

The large numbers of people with mental illness in jails and prisons has fueled policy concern in all domains of the justice system. This includes police practice, where initial decisions to involve persons in the justice system or divert them to mental health services are made. One approach to focus police response in these situations is the implementation of Crisis Intervention Teams (CIT). The CIT model is being implemented widely, with over 400 programs currently operating. While the limited evidence on CIT effectiveness is promising, research on CIT is limited in scope and conceptualization-much of it focusing on officer characteristics and training. In this paper we review the literature on CIT and present a conceptual model of police response to persons with mental illness that accounts for officer, organizational, mental health system and community level factors likely to influence implementation and effectiveness of CIT and other approaches. By moving our conceptualizations and research in this area to new levels of specificity, we may contribute more to effectiveness research on these interventions.  相似文献

Before trustees can proceed to mediation, they need to knowwhether they have a duty to resist the claim that is being mediated.Before entering into mediation, trustees need to understandits duties in relation to the claim, and the scope of compromise.Applications for blessing are two ways of protecting to enterinto a compromise. These are considered in this article.  相似文献

An important theoretical issue in the study of criminal victimization focuses on state dependence or the extent to which prior victimization causally affects subsequent victimization. Framing this issue are two conceptual arguments that posit divergent predictions regarding the impact of past victimization. While “victim labeling” suggests that the experience of prior victimization increases victimization in the future, “victim rationality” suggests that past victimization decreases subsequent victimization. To date there has been little longitudinal research that explicitly evaluates these competing viewpoints. In response, the current study uses panel data from a sample of adolescents to assess the merit of these opposing theoretical frameworks. Against this theoretical backdrop, it is shown that prevailing strategies for the analysis of panel data—random-effects and fixed-effects—produce erroneous results that add confusion to the debate regarding the nature of state dependence processes in criminal victimization. Drawing from advances in econometrics, two estimators that can overcome the problems that plague more traditional panel data models are used to provide a test of the competing victimization perspectives. Results from those analyses suggest support for the thesis that past victimization increases subsequent victimization, but the magnitude of this positive relationship is more modest than is indicated by analytic models that have been utilized in prior longitudinal victimization research.

Contracting out of public services, especially ancillary services, has been a key feature of New Public Management since the 1980s. By 2014, more than £100 billion of U.K. public services were being contracted out annually to the private sector. A number of high‐profile cases have prompted a debate about the value for money that these contracts provide. Value for money comprises both the cost and the quality of the services. This article empirically tests the contestability and quality shading hypotheses of contracting out in the context of cleaning services in the English National Health Service. Additionally, a new hypothesis of coupling is presented and tested: the effect of contracting of ancillary services on patient health outcomes, using the hospital‐acquired infection rate as our measure. Using data from 2010–11 to 2013–14 for 130 National Health Service trusts, the study finds that private providers are cheaper but dirtier than their in‐house counterparts.  相似文献

Population differences in dental development between Black and White ethnic groups have been debated but not previously studied in the UK. Using inappropriate data for dental age estimation (DAE) could lead to erroneous results and injustice. Data were collected from dental panoramic radiographs of 5590 subjects aged 6–24 years in a teaching hospital archive. Demirjian stages were determined for left-sided teeth and third molars and data collected regarding hypodontia and third molar agenesis. Third molar development in self-assigned Black British, including other self-assigned Black ethnicity, was compared with that of self-assigned White British subjects. Data were compared for males and females in the two ethnic groups using T-tests for Demirjian Stages A–G of third molar development and Mann-Whitney tests for Stage H once a cut-off age at the maximum age for Stage G had been imposed. Third molar development occurred earlier in subjects of Black ancestry compared to those of White ancestry. While both ethnic groups showed large age ranges for every third molar stage, in female subjects these generally occurred at least 1.5 years earlier, and in males at least one year earlier. Hypodontia and third molar agenesis were more prevalent in White British, but the ethnic difference in third molar development persisted in subjects with complete dentitions. This is a large study that confirms ethnic differences in a London population, emphasises the difficulties of establishing the 18-year-old threshold using DAE, and confirms the risk of overestimating the age of individuals of Black ethnicity using White ethnic reference data.  相似文献
