This paper develops a theoretical foundation to describe and explain impediments to organizational learning (OL). Based on the expanded 4I model ( Crossan et al . 1999 . Academy of Management Review , 24 , 522–537), which was further developed by Lawrence et al . (2005 . Academy of Management Review , 30 , 180–191), different learning barriers are categorized and discussed with regard to factors complicating or impeding OL. Finally, the paper analyses the impact of particular barriers on different kinds of organizational units, the relationship between OL barriers, single-loop and double-loop learning, as well as typical combinations of barriers and their respective impact on organizational performance.  相似文献

ABSTRACT

This article works to dispel the myth that Puerto Rican female urban high school students living in poverty are not capable of performing at high academic levels. This article attempts to counteract these beliefs by describing the four success factors that seven Puerto Rican female high school students attribute to their high academic achievement. These success factors are: (1) religiosity and extracurricular activities as sources of social capital, (2) affirming and maintaining a Puerto Rican identity, (3) maternal influences on students' academic achievement and, (4) the potential for caring teachers and other school staff to influence high academic achievement. Finally, our findings suggest that opportunities for Latinas and other youth of color are still inequitably structured in large, comprehensive high schools. Hence, we argue that schools must continue to bridge the large gap between themselves and the families/communities they serve and utilize the funds of knowledge and social capital that their students already bring to school.  相似文献

Economic theory predicts that individuals will free-ride, providing sub-optimal Nash equilibrium quantities of public goods. However, 25 years of experimental evidence indicates that individuals’ behavior often differs from the Nash prediction. This experiment examines provision in the context of asymmetric benefits and asymmetric costs of providing a public good with declining marginal benefits and increasing marginal costs. The design eliminates the coordination problem at the individual level inherent in previous declining marginal benefit experiments. Yet, even with the improved theoretical design, over-contribution persists, suggesting that it is a behavioral phenomenon rather than a design artifact. Analysis of individual contributions indicates that subjects’ responses to asymmetry match the theoretical prediction in 3 out of 4 single asymmetry cases. Thus, although over-contribution remains, the theoretical role of asymmetry is confirmed.  相似文献

Within social work education, there may be a failure to adequately and critically examine neoliberalism and processes of neoliberalization. In this context, those seeking to grasp the meaning of neoliberalism should be attentive to at least six interconnected components: how we might define neoliberalism in relation to the ‘embedded liberalism’ it endeavoured to supplant or displace; the role of the state within neoliberalism; the concept of ‘accumulation by dispossession’ which illuminates how neoliberalism has constantly aimed to redistribute in favour of the rich; the centrality of insecurity and precariousness; the renewed and retrogressive faith in incarceration and, more broadly, what has been termed the ‘new punitiveness’; and how neoliberalism, in practice, is often at variance with the theory and rhetoric. It will be suggested that contemporary interpretations of neoliberalism by, for example, David Harvey and Pierre Bourdieu—along with the insights of Antonio Gramsci—might aid our understanding during a period of, now perhaps, faltering neoliberalization.  相似文献

Since the late 1960s social policy scholarship has been concerned with the distribution of the resources or benefits across social gradients. This article presents a review of the literature on one mechanism by which inequity might be produced – activism by middle‐class service‐users enabling them to capture a disproportionate share of resources. The review used the methodology of realist synthesis to bring together evidence from the UK, the USA and Scandinavian countries over the past 30 years. The aim was to construct a ‘middle‐theory’ to understand how and in which contexts collective and individual activity by middle‐class service‐users might produce inequitable resource allocation or rationing decisions that disproportionately benefit middle‐class service‐users. The article identifies four causal theories which nuance the view that it is the ‘sharp elbows’ of the middle‐classes which confer advantage on this group. It shows how advantage accrues via the interplay between service‐users, providers and the broader policy and social context.  相似文献

This paper studies long-term private health insurance (PHI) in Germany. It describes the main actuarial principles of premium calculation and relates these to existing theory. In the German PHI policyholders do not commit to renewing their insurance contracts, but insurers commit to offering renewal at a premium rate that does not reflect revealed future information about the insured risk. We show that empirical results are consistent with theoretical predictions from one-sided commitment models: front-loading in premiums generates a lock-in of consumers, and more front-loading is generally associated with lower rates of lapse. Due to a lack of consumer commitment, dynamic information revelation about risk type implies that high-risk policyholders are more likely to retain their PHI contracts than are low-risk types.  相似文献

This study explores the evolution of statutory health insurance in the Republic of China on Taiwan from its inception in 1950 through to the inauguration of the National Health Insurance Programme in 1995. The main focus of the study is the timings of the adoption of the different statutory health insurance schemes targeted to the various segments of the population. It is argued that Taiwan's adoption of Labour Insurance for workers in 1950 could be best explained by the country's specific historical circumstance. The then-ruling Nationalist government was keen to build up Taiwan as a showcase for the whole of China. The inauguration of the National Health Insurance Programme in 1995 was predominantly subjected to the Nationalist government's adjustment to its changing political position.  相似文献
