This qualitative study aims to interpret the results of a randomized controlled trial comparing two educational programs (directed learning and self-directed learning) in evidence-based medicine (EBM) for medical students at the University of Oslo from 2002 to 2003. There is currently very little comparative educational research in this field. In the trial, no statistically significant differences between the study groups were shown for any outcomes considered (EBM knowledge, skills, and attitudes). Further analysis suggests that main reason for the negative trial results was that the majority of students learned equally effectively, whichever program they received, although implementation of the educational programs was not complete because of varying attendance. This study illustrates a stepwise evaluation model that might be useful in evaluating other socially complex interventions. 相似文献

The widespread application of technology in health care has imposed a broad range of challenges. The field of health technology assessment (HTA) is developed in order to face some of these challenges. However, this strategy has not been as successful as one could hope. One of the reasons for this is that social and ethical considerations have not been integrated in the HTA process. Nowadays however, such considerations have been included in many HTAs. Still, the conclusions and recommendations of the HTAs are not followed. The reason for this may be that the methods for integrating ethics for HTA are not sufficiently developed, or that they are not adequate. This article presents a supplementary approach to the ethical inquiry in HTA. It is argued that a value analysis is crucial in order to address the ethical issues of health care technology in a fruitful way and to make viable decisions about such technology.

The career-plateau as challenge to enterprises, employees and consultantsThe authors intend to link life-span-psychology to career-research in order to make understand the phenomenon of career-plateau and how individuals and organisations can deal with it. People take stock in the middle of their lives and assess their personal or professional targets. This process often relates to a personal crisis, especially when the success rate of a job is an important part of the self-concept and hierarchical development has stopped simultaneously. Nevertheless, the desire for a career continues to exist. On top of that what makes it even harder is that the individual has to work at least 20 more years because of demographic reasons. We assume that the way how to manage this crisis has a big influence on performance motivation and that life-span-orientated management development can help the individual to overcome the crisis or even prevent it. 相似文献

The concept of “liability of foreignness” — the costs of doing business abroad — has been known and discussed since the mid-1970s. At the core of these discussions is the role that firm capabilities play in overcoming or limiting these costs. This raises the question of how firms with inappropriate, limited or constrained capabilities relative to their host environment overcome the liability of foreignness. This paper focuses on the subsidiaries of “emerging multinationals” and how they manage the demands of a technologically and economically highly developed host country. A host location with sophisticated markets and well-developed institutional infrastructure may be a highly challenging environment for firms that have grown their organizational capabilities in less developed contexts. This paper explores that situation and considers how resources available on the market — for example through supplier inputs — assist subsidiaries to benefit from their presence in a munificent location. Despite the acknowledged limitations of a transaction-based approach, this paper presents evidence that purchasing knowledge provides an accessible strategy for overcoming some liabilities of foreignness. 相似文献

This study analysed self-assessed quality of life (QoL), using a QoL questionnaire (H?rnquist's QLcs) covering the life spheres, somatic health, mental well-being, cognitive ability, social and family life, activity, financial situation, meaning in life and a global score "entire life", in 487 unemployed subjects and 2917 employed subjects aged 25-64, in a population-based cross-sectional study in northern Sweden. In line with previous findings, results showed that unemployed people exhibited poorer QoL. Unemployed women scored higher in existential life domains than unemployed men did. Unemployed men were worst off in terms of general life situation. Employed respondents benefited in QoL by a university/college education, while unemployed respondents with a university/college education did not. Close social relations and money reserve were associated with higher QoL generally. It was concluded that further research is needed to differentiate various aspects of QoL and unemployment, and to compare with other samples. 相似文献

It is a stylized fact that marriage formation involves positive assortative matching on education. We also find this in the
case of immigrants, even when they tend to “import” their spouses and potentially trade off education for other favorable
characteristics. For Pakistanis, we find positive compensating differentials in terms of high education to youth having adopted
host country norms, when marrying a marriage migrant. This indicates that Pakistani marriage migrants pay a premium to be
able to marry and live in Denmark. For Turks, individuals having source country norms pay a premium in order to import a partner,
indicating that unspoiled traditional norms are traded off for education.

The fair value-option in IAS 39 allows fair value measurement for liabilities. It is often criticized that a change in a company’s own credit risk affects the value of its liabilities. Therefore it is doubtful whether the fair value-option is in fact useful for investors’ decision making process. Due to a lack of empirical studies concerning the understandability and the decision usefulness of the fair value-option, this paper contains the results of an experimental investigation. We find that investors are misled by fair values for liabilities, though under some circumstances they learn to interpret the financial data correctly. We compare fair value measurement of liabilities with an accounting treatment based on German GAAP. 相似文献

The audit fees available since 2005 as a consequence of the Bilanzrechtsreformgesetz (commercial code reform act) show an extremely high supplier concentration on the German audit market of publicly listed companies. This justifies the assumption of audit fees above perfect market equilibrium prices. However, the complete collection and multivariate regression analysis of all relevant audit fee and client data document a 24 % decrease in audit fees in 2005 and an average 15 % decrease in the two subsequent years due to auditor changes. This can be interpreted as an indicator for price competition. In addition, the audit fee data shows that the audit fee decreases are only partially compensated by subsequent increases. As a consequence, there is no evidence for lowballing at present. Further time series are necessary to show if the current trend is sustainable. 相似文献

In elementary probability theory, as a result of a limiting process the probabilities of aBi(n, p) binomial distribution are approximated by the probabilities of aPo(np) Poisson distribution. Accordingly, in statistical quality control the binomial operating characteristic function \(\mathcal{L}_{n,c} (p)\) is approximated by the Poisson operating characteristic function \(\mathcal{F}_{n,c} (p)\) . The inequality \(\mathcal{L}_{n + 1,c + 1} (p) > \mathcal{L}_{n,c} (p)\) forp∈(0;1) is evident from the interpretation of \(\mathcal{L}_{n + 1,c + 1} (p)\) , \(\mathcal{L}_{n,c} (p)\) as probabilities of accepting a lot. It is shown that the Poisson approximation \(\mathcal{F}_{n,c} (p)\) preserves this essential feature of the binomial operating characteristic function, i.e. that an analogous inequality holds for the Poisson operating characteristic function, too. 相似文献
