This article reviews the Critical Management Education (CME) literature produced since 1995 and compares its development in the United Kingdom with that of the United States. It explores the relationship between CME, as an academic field, and that of Critical Management Studies (CMS), the wider movement that deploys critiques drawn from sociology and political science perspectives. In the UK, the origins of CME are in established debates about utilitarian versus liberal education and in radical adult education theory—quite separate from the CMS movement. In the US however, the article argues that business schools and the academy are sites that the CMS is attempting to colonise and CME cannot, in that context, be separated from the CMS project.  相似文献

Commissioned by Craver, Mathews, Smith & Company (CMS), this study takes an in-depth look at donors to charitable and progressive social change organizations at the close of the 20th century. As a follow-up to the benchmark donor study sponsored by CMS in 1990, the current research allows for some basic comparisons between donors at the beginning and end of the decade.  相似文献

La expansión de las cadenas mundiales de suministro (CMS) desconecta la ubicación de los empleos de la demanda correspondiente. Los autores utilizan la base de datos mundial de insumo‐producto (WIOD) para examinar estos vínculos en 40 países en el periodo 1995–2013, ampliar anteriores análisis de la OIT y proporcionar evidencia sobre el empleo creado por cada combinación ubicación del empleo‐destino de exportación. Observan un cambio en los patrones de demanda y oferta de empleo en las CMS, un auge de China como generadora de demanda, mayores vínculos de producción entre las economías emergentes y más empleos en los servicios sostenidos por las CMS manufactureras.  相似文献

This article investigates the organizational changes triggered by the implementation of certified management systems (CMS) in Denmark and explores how institutionalized organizational practices change over time. The study shows that improvements in performance were not significant in the implementation of CMS, though in most cases its adoption implied organizational changes. The study also shows that the search for external legitimacy was appropriated by various internal organizational actors, other than management. When internal actors share the institutionalized beliefs and norms of the wider society, they implicitly strive to reduce decoupling. We argue that understanding the social dynamics of legitimacy in organisations requires paying attention to the agency of superordinated as well as subordinate actors.  相似文献

The fit between manufacturing strategy and the use of cost management systems that could effectively support a firm's information needs in strategic and operational decision-making is prerequisite for a firm's ability to attain desired objectives in its value chain. The primary purpose of this study is to examine the relationship between the use of just-in-time and electronic data interchange systems, as an important dimension of a firm's manufacturing strategy, and the perceptions of top financial officers about the effectiveness of cost management systems in supporting strategic and operational decision needs. The results for the research hypothesis, which was examined using a sample of 604 manufacturing organizations in the USA, provided some support for the argument that perceptions of effectiveness of a firm's CMS can be a valid indicator of how well is the CMS designed to support strategic and operational decision needs that are necessary for the implementation of a firm's manufacturing strategy.  相似文献

基于江苏省2073个实地调研数据,利用样本选择模型及分位数分解方法,实证研究统筹城乡医疗保障制度的福利分配效应.实证结果表明,统筹城乡医保制度更多地将医保补偿福利分配给高风险人群、高收入阶层和农村居民.针对不同收入阶层的福利差异,分位数分解结果进一步证实:允许参保自选的统筹模式在缩小贫富人群、城乡人群的医保补偿差异上也更具优越性,并且这种优越性多来自于统筹模式本身,而非地区禀赋差异.  相似文献

As adopting information and communications technology to deliver instruction and facilitate learning, course management systems (CMSs) offer an alternative capability to enhance management practices. Based on innovation diffusion theory, this study explores CMS effectiveness (EF) and reliability (RL), and considers both perceived innovative attributes (IA) and demographic characteristics. This study also exams the moderating effect of complexity (CX) and mediating effect of function evaluation (FE) on the causal relationship between IA and outcome variables (i.e., EF, RL). Analysis also includes the differential effects of three types of CMSs and gender differences. Participants were 238 undergraduates, majored in business or management, who volunteered to complete an online survey. Results show that perceived IA affect RL and EF, but not FE. CX moderates the effect of perceived IA on RL, but does not moderate the effects of perceived IA on FE and EF. EF, but not FE, appears to mediate the effects of perceived IA on RL. There is no significant difference in model fit between genders, but there is among the type of CMS solution group. Conclusions and implications are offered regarding the future research for program leaders and practitioners.  相似文献

Abstract

The present work explores employee acceptance of process innovation in a public administration from a complementary three-fold theoretical perspective, the Technology Acceptance Model (TAM), the Cognitive Model of Satisfaction (CMS) and the Satisfaction-loyalty Model (SLM). The proposed model integrates these approaches, and considers the moderating effect of employees' perceived experience with the new process. Although findings support that behavioural intentions are determined by perceived usefulness, satisfaction and attitude towards the new technology, we find that as employees' perceived experience increases, use intention becomes a routine, and the evaluation of the new process proves irrelevant in terms of usefulness or quality.  相似文献
