This research analyses, first, whether top management support for information and communications technologies has positive consequences for knowledge management by analysing the specific influence of top management support for ICTs on each of the knowledge management processes (knowledge acquisition, transfer, and utilisation). Second, it analyses the influence of each knowledge management process on organisational performance. The theoretical model is tested using data collected from March to May 2010 from 201 CEOs in Spanish technology organisations. The results indicate that the stage-based disaggregation of the knowledge management process into knowledge acquisition, transfer, and utilisation, and the three-stage management process are the mediating mechanisms in the relationship between top management support for ICTs and organisational performance. CEOs should thus support the information and communication technologies necessary to improve all of the interrelated stages of knowledge management as a mechanism for achieving better organisational performance. Various strategic actions should be stimulated within the organisation to intensify the interrelation between these stages of acquisition, transfer, and utilisation of knowledge.  相似文献

This study integrates the results of quantitative and qualitative methods to elucidate the association between sexual identity and physical and sexual abuse among Puerto Rican drug users. A structured questionnaire was administered to 800 subjects in New York and 399 in Puerto Rico. A total of 93 subjects (7.9%) self-identified as homosexual or bisexual. Gay males were significantly more likely than heterosexual males to report first occurrence of physical abuse by a family member in childhood. Both gay and bisexual males were more likely than their heterosexual counterparts to report first experiencing unwanted sex in childhood and intimate partner physical abuse later in life. Lesbians were more likely than female heterosexuals to report unwanted sex in childhood. Qualitative data were collected through in-depth life histories with 21 subjects and suggest that gay and lesbian subjects perceive antihomosexual prejudice on the part of family members as one cause of childhood physical and sexual abuse.  相似文献

The aim of the paper is to demonstrate the appropriateness of an a priori analysis to determine the distributional assumption of the inefficiency term in a stochastic frontier model. To this end, theoretical distributions of estimated inefficiency were obtained when the inefficiency term is assumed to be distributed as a half normal and an exponential in a cost frontier model. Comparisons of such theoretical distributions with the respective cost inefficiency estimators using the goodness of fit test allow selecting the most appropriate distributional assumption. The application on three data sets of Spanish banking system in 2009 demonstrated the relevance of the research question. First, the results of estimated cost inefficiency with a half normal assumption are larger than with an exponential distribution significantly. Besides, half normal assumption was rejected and exponential was not rejected as the most appropriate distribution of inefficiency term in Spanish banking data set. However, the adjustment of saving banks data had been better with the former distribution than the latter. In the case of banks, any distribution results appropriate. To sum up, this work demonstrate that the distributional assumption on inefficiency term in Stochastic Frontier Approach must be established in a justified way, as it can significantly bias the results of estimated inefficiency and therefore, influences improving policies and strategies in the Spanish banking sector.  相似文献

Measuring welfare state generosity in developing and transitional welfare states is often challenged not only by lack of comparative quantitative data, but also by issues of conceptual stretching. This paper demonstrates and discusses the use of one of the key measures of welfare entitlement generosity developed in the comparative welfare state research in the context of post-communist countries of Central and Eastern Europe (CEE). With the new time series data provided by the Comparative Welfare Entitlements Dataset CWED2, comparative approaches including the CEE countries have become feasible. This paper first discusses quantitative measures of welfare entitlement generosity in the tradition of the social rights of citizenship approach and how they can be applied for cross-country comparisons. It then demonstrates empirically how the emerging CEE welfare states’ generosity compares to mature “old” OECD welfare states. Finally, the paper shows the potential and the pitfalls of quantitative measures of welfare state generosity by discussing, to what extent do indicators of social security scheme generosity measure the same in established and emerging welfare states, which functional equivalents may be relevant in the context of emerging welfare states and how far can we stretch our theoretical concepts.  相似文献

This study assessed ethnic and gender differences in ideal body size, body dissatisfaction (BD), and the relationship between BD and various predictors (e.g., body composition indicators and cardiorespiratory fitness). The sample consisted of 190 White and Hispanic preadolescents aged 10–13 years. Demographic, percent body fat (%BF), body mass index (BMI), body image variables, and cardiorespiratory fitness (CRF) were examined. A significant Gender × Ethnicity interaction was found for ideal body size (< .05), with Hispanic girls preferring the thinnest figures and Hispanic boys the largest figures, compared to their counterparts. No significant gender or ethnic differences in BD were observed. After controlling for demographic and cultural variables, increased %BF and BMI scores predicted greater BD, whereas CRF did not.  相似文献

In the context of the reform of defined benefit pension systems under population ageing, we focus on the introduction of automatic adjustment mechanisms linked to life expectancy. Our goal is to establish a relationship between changes in the key parameters of the pension system and changes in life expectancy, applying the principle of intergenerational actuarial neutrality. For a defined benefit pension scheme, we first obtain the fundamental adjustment equation and then, for particular cases, we derive different designs of automatic adjustment mechanisms depending on the involved parameter. We include a numerical application only for illustrative purposes.  相似文献

Lights and shadows on sustainability rating scoring   总被引:1,自引:1,他引:0  
Many organizations currently publish sustainability ratings that quantify the sustainability of firms by aggregating scores. These organizations analyze companies in economic, social, environmental and corporate governance terms. However, some of these scores are associated with problems of how positive and negative assessments are offset. This work proposes a methodology for using fuzzy logic in the design of a comprehensive sustainability rating for firms. This technique for measuring sustainability addresses the complexity of the concept and enables the incorporation of expert knowledge into the system of assessment. This approach is applied to organizational information taken from the 2008 Accountability Rating and corrects one of the weaknesses revealed by methodologies based on the aggregation of scores—the offset effect—enabling decision-maker to manage it. This is considered an important research topic because of the growth of social responsible financial markets, and the fact that investors are demanding more accurate information.  相似文献

Over the last decade there has been growing interest in understanding the relationship between corruption and economic performance. The principal motivation of this work is to analyze whether corruption affects the economic results of OECD countries from a productivity-based perspective. To this end, we shall adopt a frontier approach which will allow us, on the one hand, to study whether corruption conditions the efficiency levels at which the economies perform and, on the other, to determine the channels through which it can affect productivity growth, whether by influencing improvements in relative efficiency levels or by shifting the production frontier.  相似文献

This paper presents the lessons learned through a process evaluation (PE) after 1 year of implementation of a 2-year community intervention in Lima, Peru. The intervention consisted of training and motivating community popular opinion leaders (CPOLs) for three marginal population segments to disseminate prevention messages among their peers. PE data included: observations, qualitative interviews with CPOLS, conversations and messages delivered by CPOLs, training facilitators' perceptions about implementation, and a survey of CPOLs. The PE helped to document and enhance the intervention. CPOLs were motivated to talk to their peers. CPOLs perceived that their participation had an effect on their own risk behaviors and saw their role as beneficial to their community. The PE was helpful in examining training delivery and the feasibility and acceptability of the intervention in order to assess the elements related to program success necessary to replicate the CPOL model.  相似文献
