By considering uncertainty in the attributes common methods cannot be applicable in data clustering. In the recent years, many researches have been done by considering fuzzy concepts to interpolate the uncertainty. But when data elements attributes have probabilistic distributions, the uncertainty cannot be interpreted by fuzzy theory. In this article, a new concept for clustering of elements with predefined probabilistic distributions for their attributes has been proposed, so each observation will be as a member of a cluster with special probability. Two metaheuristic algorithms have been applied to deal with the problem. Squared Euclidean distance type has been considered to calculate the similarity of data elements to cluster centers. The sensitivity analysis shows that the proposed approach will converge to the classic approaches results when the variance of each point tends to be zero. Moreover, numerical analysis confirms that the proposed approach is efficient in clustering of probabilistic data.  相似文献

Although estimating the five parameters of an unknown Generalized Normal Laplace (GNL) density by minimizing the distance between the empirical and true characteristic functions seems appealing, the approach cannot be advocated in practice. This conclusion is based on extensive numerical simulations in which a fast minimization procedure delivers deceiving estimators with values that are quite far away from the truth. These findings can be predicted by the very large values obtained for the true asymptotic variances of the estimators of the five parameters of the true GNL density.  相似文献

A multiple state repetitive group sampling (MSRGS) plan is developed on the basis of the coefficient of variation (CV) of the quality characteristic which follows a normal distribution with unknown mean and variance. The optimal plan parameters of the proposed plan are solved by a nonlinear optimization model, which satisfies the given producer's risk and consumer's risk at the same time and minimizes the average sample number required for inspection. The advantages of the proposed MSRGS plan over the existing sampling plans are discussed. Finally an example is given to illustrate the proposed plan.  相似文献

Evaluation capacity building (ECB) is a context-dependent process. Contextual factors affecting ECB implementation have been explored theoretically and practically, but their influence within a changing environment has seldom been discussed. This study examined essential context-sensitive parameters, particularly those involved in implementing new governmental policies regarding higher education. Taiwan was used as a case study for exploring the effect of contextual change on ECB attributes from the perspectives of training receivers and providers. Surveys and interviews were used for data collection and importance–performance analysis was applied for data analysis. Four prominent features were identified. First, the ECB attributes perceived as important by receivers were performed adequately, whereas those perceived as less important were performed less well. Second, under new policies, training provider designed training covering a wide range of ECB, whereas receivers focused on those can be directly applied in evaluation process. Third, in a small education system such as Taiwan’s, the complexity of peer review is high and ethical issues become important. Fourth, because the evaluation structure has been changed from single- to dual-track, receivers expect more training for institution staff, whereas providers insist on hierarchical training. Aligning ECB supply and needs is paramount for adaptation to new policies.  相似文献

In the 1990s, Canadian universities began implementing policies to accommodate learning disabled students. While such policies appear to make post-secondary education more accessible, students must manage considerable complexity and absorb social and financial costs to receive accommodations. Through interviews with learning disabled students, this research explores the effects of socio-economic status (SES) on how, or whether, students access accommodations at a Nova Scotian university. Drawing on the work of Bourdieu and Goffman, this study suggests that SES affects students’ abilities to navigate the accommodation process successfully, and that accommodation policies, while important, may not ensure equal access to accommodations.  相似文献

This paper captures the experiences of the faculty members of a relatively new graduate social work program situated in the largely rural state of Haryana India in reframing the foundation year practicum through community-based and engaged action learning in small villages. Located within Bhagat Phool Singh Vishwavidyalaya (BPSMV), north India's first all women public university, the mission of which is to enhance women's engagement in the greater society through post-secondary, professional and character education, the department is educating social workers for community engagement in social development and in the development of women as an empowered group in society, particularly at the village level. Over a three-year period, the faculty has successfully launched and sustained action learning as an alternative to the traditional practicum in social work education, enhanced civic engagement among students and faculty in three rural villages, and further developed community social work as a principal focus of social work education in India. The paper offers a rationale for action learning in the graduate social work curriculum, describes and documents the department's strategy of action learning, and lays out lessons learned from action learning as a central focus of pedagogy, research, and service within BPSMV Department of Social Work and the rural villages it serves.  相似文献

Course leaders have adopted a relatively cautious approach to involving service users and carers in Post-Qualifying (PQ) social work management education programmes in the UK, looking for opportunities in which it ‘makes sense’ for them to be included. Whilst there is, to a certain extent, the belief that involving service users and carers in PQ social work education is ‘a good thing’, it has proved challenging to implement. This research study sought to explore, through interviews with ‘experts’ in the field, why this process had proved so challenging. A term which emerged during the research was the importance of ‘meaningful involvement’. The research explored what ‘meaningful involvement’ might mean for managers, for academics and also for service users and carers; what it looks like and how might it take forward the understanding of and the preparation for PQ social work management education.  相似文献
