The UK and Italian research assessment exercises face to face 总被引：1，自引：0，他引：1
In the UK the Research Assessment Exercise (RAE) is being replaced by the Research Excellence Framework (REF); similarly, in Italy the former Research Evaluation Exercise (VTR 2001–2003) has been revised and extended and a new cycle of assessment was activated in Autumn 2011 (VQR 2004–2010). The analysis of the development and the consequences of both British and Italian assessment exercises is carried out on the basis of three theoretical frameworks – new public management (NPM), neo-institutional sociology (NIS), and organisational control theory (OCT). This last framework is crucial because the control systems have an effective sense-making capacity and it also exposes a different awareness about control systems in the British and Italian experiences. 相似文献

Ethical protocols design 总被引：1，自引：0，他引：1
Matteo Turilli 《Ethics and Information Technology》2007,9(1):49-62
The paper offers a solution to the problem of specifying computational systems that behave in accordance with a given set
of ethical principles. The proposed solution is based on the concepts of ethical requirements and ethical protocols. A new conceptual tool, called the Control Closure of an operation, is defined and used to translate ethical principles into ethical requirements and protocols. The concept
of Generalised Informational Privacy (GIP) is used as a paradigmatic example of an ethical principle. GIP is defined in such a way as to (i) discriminate specific
cases in which an individual’s GIP can be infringed without accessing the individual’s data; (ii) separate unauthorised accesses
to data that do not respect the right to GIP from access that do; and (iii) distinguish different degrees of GIP. Finally
a camera phone is used to illustrate the proposed solution. 相似文献

The importance of groupware tools in e-learning practice is increasing, because of their educational relevance and of the
importance of group abilities in today’s job activities. The paper addresses some critical issues of asynchronous collaborative
tools hosted in Web-learning platforms. A model to capture user quality perceptions for these tools is presented, and an investigation
conducted in three case studies where e-learning platforms were used to share and comment on written works is reported in
detail. Quantitative and qualitative data are used in a complementary way to capture the complexity of educational collaborative
activities. The impact of technologies on work organization, writing and peer-feedback activities is discussed. Users dedicated
more time to feedback activities than they would have in real-life contexts, and paid more attention to the style and content
of their writing. Communication was more focused and honest than in real life (even though more distant and at the risk of
misunderstanding), and its indirectness encouraged shy and impaired people. Usability problems emerged from platform design,
educators’ choices and server-side settings; Web-based systems seem to pose specific usability issues when users are required
a strong active role; compatibility issues highlight the need for a closer Web standard compliance.

One of the most significant results of the qualitative literature on national systems of innovation (NSIs) is that different systemic arrangements (i.e. configurations of actors and institutions) can deliver similar levels of innovative performance. Using factor analysis on a novel dataset of 29 quantitative indicators of innovative activities we provide an empirical characterization of the structure of European NSIs over the last ten years. Our results cast doubt on the empirical significance of the “equifinality” of heterogeneous systemic arrangements in the context of NSI. Innovation systems show inherent complexity, which leads to a high level of complementarity among their constituent components and configuration. This result implies that successful innovation policies should be systemic, leaving little flexibility in policy design and scope. 相似文献

Introduction
The aim of this study was to identify clinical variables which may be independently associated with positivity of a cardiac troponin I (cTnI) assay in a large population of patients admitted to the emergency department (ED).Materials and methods
3166 subjects, with at least two troponin I tests ordered within 6 hours in the ED, were studied. Patient data were statistically analyzed to identify clinical associations with increased values of Troponin I.Results
Although patients with diagnosis of acute coronary syndrome displayed troponin I values significantly higher than those of other groups, positivity to troponin I (> 40 ng/L) was also observed in patients with other clinical conditions. In multivariate analysis, age, elevated heart rate and electrocardiographyc changes were independently associated with troponin I positivity at admission. In the whole study population troponin I positivity exhibited high sensitivity and negative predictive value, counterbalanced by low specificity and limited positive predictive value.Conclusions
Troponin I positivity should be combined with history and clinical evaluation and cautiously interpreted in the ED, especially in patients exhibiting factors associated with higher troponin I levels such as older age, elevated heart rate or ECG changes.Key words: troponin I, acute coronary syndrome, emergency service, hospital, chest pain 相似文献56.
This paper investigates the determinants of economic growth from both a theoretical and an empirical perspective. The paper combines the supermultiplier model of growth with the Neo-Schumpeterian framework that emphasises the entrepreneurial role of the state. We aim to detect the macroeconomic effect generated by alternative fiscal policies: generic ones and more directed ‘mission-oriented’ ones. Using an SVAR model for the US economy for the 1947–2018 period, we show that mission-oriented policies produce a larger positive effect on GDP (fiscal multiplier) and on private investment in R&D (crowd-in effect) than the one generated by more generic public expenditures. 相似文献

This paper focuses on assessing possible levers in the hands of a university’s top management team for inducing or managing change when faced with environmental drives. The topic is discussed after analysing change in a university over a 20-year period. The case study underlines the opportunities and difficulties of linking external environmental drives and change processes, highlighting the lack of a universal path and proposing elements that are worthy of attention. The paper underlines the need for top management teams in universities to pay particular attention to the systemic and balanced aspects of the factors determining change.

This study examined the physical differences in adult male basketball players of different competitive level and playing position using a large cohort. In the middle of the regular season, 129 players from four different Divisions completed a Yo-YoIR1 and, after 3-to-8 days, they performed a 6-min continuous running test (Mognoni’s test), a counter-movement jump (CMJ) test and a 5-min High-intensity Intermittent running test (HIT). Magnitude-based inferences revealed that differences in HIT were very likely moderate between Division I and II and likely small between Division II and III. The differences in absolute peak power and force produced during CMJs between Division I and II and between Division II and III were possibly small. Differences in Yo-YoIR1 and Mognoni’s test were very likely-to-almost certain moderate/large between Division III and VI. We observed possibly-to-likely small differences in HIT and Mognoni’s test between guards and forwards and almost certainly moderate differences in absolute peak power and force during CMJs between guards and centres. The ability to sustain high-intensity intermittent efforts (i.e. HIT) and strength/power characteristics can differentiate between competitive level, while strength/power characteristics discriminate guards from forwards/centres. These findings inform practitioners on the development of identification programs and training activities in basketball. 相似文献
