Ethical leadership and ethical decision making in organizations have been the focus of many concerns related to ethics, especially in light of high-profile corporate scandals. The importance of educational preparation for ethical leadership has been highlighted in the general literature and the library and information science literature. This article is based on a meta-analysis of research related to ethics education in business. The meta-analysis considers issues of research design, methodologies used, populations studied and other data analyzed, the nature of the researchers, and the dissemination of the research in the journal literature. It is intended to inform the study of ethics and ethics education in general and in other professional disciplines, such as library and information science. The research results indicate the limited number of research methodologies that have been used in the study of ethics education. Past research has largely focused on undergraduates, particularly in relation to the impact of ethics curricula on their learning/cognitive development and on measures of perceptions and changes in perceptions of ethical issues.  相似文献

Resistance theory approaches questions of structure and agency as a divide. Resistance crosses boundaries of class, race and gender, but does not point to actions likely to lead to change in present social relations. There is a need to move beyond limited resistance perspectives to focus on individuals and groups as creative agents able to effect change in social structures. A more dynamic theory of individual, social and cultural change is needed to enable an understanding of how educational settings–including curriculum, pedagogy, and assessment practices–can help bring about just social outcomes for all students. This article draws, in particular, on the work of Willis, Walker, Giddens, and Bernstein to address questions of agency and structure in accounting for educational and social change.  相似文献

This article provides a review of the inconclusive debate between Hansen-Weisbrod and Pechman on the distributional effects of subsidies to public higher education in California, with particular reference to its significance for other American states and for European countries. The cross-sectional effects are distinguished from the longitudinal, lifetime effects, and an effort is made to state the necessary and sufficient conditions to infer lifetime redistributive effects from observations of current data. Some general conclusions are drawn for the case of the United Kingdom.  相似文献

We compared the efficacy of three physical conditioning programmes provided over a 12 week period (24 h in total) on selected anthropometric and physical fitness parameters in female soccer players. Two of the groups received physical conditioning training in accordance with speed, agility and quickness (SAQ); one group used specialized resistance and speed development SAQ equipment (equipment group; n = 12), while the other group used traditional soccer coaching equipment (non-equipment group; n = 12). A third group received their regular fitness sessions (active control group; n = 12). All three interventions decreased (P < 0.001) the participants' body mass index (-3.7%) and fat percentage (-1.7%), and increased their flexibility (+14.7%) and maximal aerobic capacity (VO2max) (+18.4%). The participants in the equipment and non-equipment conditioning groups showed significantly (P < 0.005) greater benefits from their training programme than those in the active control group by performing significantly better on the sprint to fatigue (-11.6% for both the equipment and non-equipment groups versus -6.2% for the active control group), 25 m sprint (-4.4% vs -0.7%), left (-4.5% vs -1.0%) and right (-4.0% vs -1.4%) side agility, and vertical (+18.5% vs +4.8%) and horizontal (+7.7% vs +1.6%) power tests. Some of these differences in improvements in physical fitness between the equipment and non-equipment conditioning groups on the one hand and the active control group on the other hand were probably due to the specificity of the training programmes. It was concluded that SAQ training principles appear to be effective in the physical conditioning of female soccer players. Moreover, these principles can be implemented during whole team training sessions without the need for specialized SAQ equipment. Finally, more research is required to establish the relationship between physical fitness and soccer performance as well as the principles underlying the improvements seen through the implementation of SAQ training programmes.  相似文献

This study examined age-related differences in the role of visual proprioception during a lower limb interceptive action and how this varies as a function of skill and practice. In Experiment 1, skilled and less-skilled 8-, 10-, and 12-year-old boys controlled a soccer ball using their preferred foot under full vision and when sight of the effector was occluded. With the exception of the high-skilled 12-year-olds and low-skilled 8-year-olds, participants showed a decrement in peformance when denied access to visual proprioception. In Experiment 2, the effect of practicing under different informational constraints was examined for 12 year-old boys. Children performed varying amounts of practice under full vision, or in a condition where sight of the foot was occluded, before being transferred to the alternative viewing condition. Participants who practiced under occluded viewing conditions showed greater relative improvement in performance over practice and transfer sessions compared with a full vision control group. Some support is provided for the manipulation of visual informational constraints as an effective pedagogical approach to motor learning.  相似文献

This paper takes a preliminary look at the hybridization of museums – the creation of a variety of mixed forms of governance incorporating both public and private governing authorities. Using data from three national surveys of American museums, the analysis documents the mix of types of governing authority and demonstrates how this mix varies across location, over time, and by museum type. The paper then estimates the extent of hybridization using several different indicators and speculates about its implications. The United States offers a particularly informative case because the general view is that American museums are (1) either public or private and (2) predominately private. While the second part of this view may still be a useful characterization of American museums, the first is no longer a particularly helpful way of understanding American museums, or, by extension, other cultural institutions, American or not. It is increasingly necessary to view cultural institutions through the lens of hybridization rather than privatization in order to improve our ability to document and predict their institutional behavior.  相似文献

This article is an edited and condensed version of the report of a study carried out under the auspices of the Joint Information Systems Committee (JISC) and the Publishers Association (PA). It develops the conclusions of an earlier analysis (Bide, Oppenheim & Ramsden, 1997) and builds upon discussions between representatives of JISC and the PA held in the summer of 1997. The full report is available on the UKOLN server at www.ukoln.ac.uk/services/elib/papers/pa/charging/  相似文献
