abstract Situated learning theory offers a radical critique of cognitivist theories of learning, emphasizing the relational aspects of learning within communities of practice in contrast to the individualist assumptions of conventional theories. However, although many researchers have embraced the theoretical strength of situated learning theory, conceptual issues remain undeveloped in the literature. Roberts, for example, argues in this issue that the notion of ‘communities of practice’– a core concept in situated learning theory – is itself problematic. To complement her discussion, this paper explores the communities of practice concept from several perspectives. Firstly, we consider the perspective of the individual learner, and examine the processes which constitute ‘situated learning’. Secondly, we consider the broader socio‐cultural context in which communities of practice are embedded. We argue that the cultural richness of this broader context generates a fluidity and heterogeneity within and beyond communities. Finally, we argue that it is sometimes difficult to distinguish conceptually between the terms ‘participation’ and ‘practice’ because of occasional duplication of meaning. We propose, instead, a refinement of the definition to allow for greater conceptual clarity.  相似文献

Those responsible for making decisions in hospitals are increasingly aware of the need to efficiently manage hospital systems. An option for analysis is done by queuing models. In this paper is analyzed the service area ER, in a public hospital applying the concepts and relationships of waiting lines. From the model results, it is concluded that in the emergency department does not have the required minimum number of doctors to allow a steady flow of patients. With the model, the minimum required number of doctors is calculated to meet current and future demand for service with the same service time and the same discipline of service. Analytical models, allowing direct understand the relationships between service demand, number of doctors and patient care priority viewed as a queuing system. The work is useful for administrators and managers of hospital systems.  相似文献

A consortium of international organizations convened a first-ever Global Health Care Workforce Conference to discuss the worldwide shortages of health care workers and the migration patterns of health care workers from developing nations to the first world. Over 300 participants from 47 countries, including one-third from developing countries, discussed a variety of critical issues ranging from global immigration, recruitment, economics, to partnerships. Results, recommendations, and actionable items generated from the conference, as well as ways to put these ideas into practice, will be critical for sustaining and improving world health and the plight and numbers of health care providers.  相似文献

Leadership theories abound in individualistic societies with the promise that anyone can become a successful leader by following certain guidelines. However, many of our existing theories are culturally specific to individualistic societies with low power distance. People from more collectivist cultures, in which power distance is greater, have a very different perspective of what they can do. In the current paper, I discuss how followership can be helpful for empowering people in large power distant cultures and offer five strategies, using Honduras as an example. The strategies are based on a theoretical examination of basic followership concepts with Hofstede's cultural dimensions of power distance and collectivism (Hofstede, Hofstede, & Minkov, 2010).  相似文献

Individual or personal budgets are part of a growing international trend to encourage greater choice and control over social care services at a time of financial austerity. The authors' evaluation of individual budgets found that levels of allocated resources reflected a range of factors, including informal or carer support and disability levels. Furthermore, individual budgets were found to be cost-neutral compared with conventional social care delivery.  相似文献

As developing countries open themselves up to trade, many industrial firms in these countries are finding it difficult to compete internationally due to poor product quality and low product variety. Although China has been the largest producer of crude steel since 1996, China's steel firms have produced an overabundance of low-quality steel while domestic purchasers of steel have increasingly demanded higher quality steel products. Many have argued that for Chinese steel firms to improve product quality they must adopt more advanced technologies. Employing firm-level panel data of steel firms in China, we econometrically test the relative importance of two possible sets of factors affecting a firm's ability to utilize technology to improve product quality: technology acquisition factors and technology absorptive capacity factors. We find that technology complements such as in-house R&D and foreign knowledge must be combined with technology for Chinese firms to improve product quality.  相似文献

There are three challenges to household economic security: Slow income growth at the lower and middle parts of the income distribution, swings in households’ use of debt and leverage, and large numbers of households with low savings. Appropriate policy responses to these include increasing worker skills through greater opportunities for education and training, removing barriers to labor force participation, strengthening the safety net, improving access to credit while reducing exposure to harmful aspects of debt use, and making retirement savings easier and more automatic.  相似文献

One of the main concerns associated with the development and use of regional CGE models is the determination of key parameter values, particularly substitution and other price elasticities. A common problem is the lack of appropriate regional data for econometric estimation. Consequently, it is important to identify key parameters that are likely to be important in determining quantitative results and then to prioritize these for estimation where appropriate data are available. In this paper, the focus is on the estimation of the regional trade (import) substitution parameters, which tend to be important in analysis for regional economies (given their openness to trade). Here, commodity import elasticities for the Illinois economy are estimated and tested in a single region CGE model of the Illinois economy. In our econometric estimation, we apply a model that takes account of market size and distance in estimating the substitutability between commodities produced in Illinois and other US states.  相似文献
