This article reports on an evaluation of women's Self Help Groups(SHGs) in an area in south India. Groups were evaluated, notin terms of their success as microcredit schemes, from a financialperspective, but in relation to their contribution to genderdevelopment. Evidence emerged that women perceived changes intheir identity towards working collectively to influence forchange at the village and panchyat levels. They engaged in communityand social action programmes, both at the local level and byjoining with issues beyond the local. When considered withinconstructs of empowerment, capability poverty, citizenship,and participation in democratic processes, such SHG outcomes,and the community development processes that accompany theirwork, can be seen to make a modest but significant contributionto broader transformations of oppressive structures.  相似文献

The importance of client beliefs in career counseling depends on their ability to add unique information about the client over and above that contributed by aptitudes and interests. The Career Beliefs Inventory was administered to 200 Australian students in grade 10 together with measures of Holland's RIASEC interest themes and scholastic aptitudes. The correlations between scales from the three domains showed clearly that beliefs made a contribution distinct from that provided by aptitudes and interests. Even though the results may reflect possible sampling or method variance, career beliefs in this sample added unique information to that traditionally used in career counseling.  相似文献

The Duckworth–Lewis method for adjusting targets in rain-interrupted one-day cricket matches is used throughout the world, but, as Frank Duckworth explains, he originally came to statistics from physics via metallurgy, and only thought of applying statistical methods to sport when their power became apparent to him during his career in the nuclear energy industry  相似文献

Abstract An examination of big‐city newspaper coverage of violent crimes in small towns during a recent five‐year period reveals a remarkable degree of uniformity in the language reporters use to characterize life in these places. The cliches signal an underlying set of stereotypes of small‐town life: They are safe, close‐knit communities where bad things are “not supposed to happen.” Yet the point of the stories is that bad things do happen. Drawing upon culturological and sociological approaches to the study of news production, this paper argues that the small towns described in the news are symbolic landscapes that reflect a pastoral orientation among journalists and in the culture at large.  相似文献

In attempting to manage their practices efficiently, doctors may not allow seriously ill patients enough time to sort out their feelings and raise important questions. What is at stake here is not information about prognosis and treatments but the very survival of the soul.  相似文献

Evolution strategies (ESs) are a special class of probabilistic, direct, global optimization methods. They are similar to genetic algorithms but work in continuous spaces and have the additional capability of self-adapting their major strategy parameters. This paper presents the most important features of ESs, namely their self-adaptation, as well as their robustness and potential for parallelization which they share with other evolutionary algorithms.Besides the early (1 + 1)-ES and its underlying theoretical results, the modern ( + )-ES and (, )-ES are presented with special emphasis on the self-adaptation of strategy parameters, a mechanism which enables the algorithm to evolve not only the object variables but also the characteristics of the probability distributions of normally distributed mutations. The self-adaptation property of the algorithm is also illustrated by an experimental example.The robustness of ESs is demonstrated for noisy fitness evaluations and by its application to discrete optimization problems, namely the travelling salesman problem (TSP).Finally, the paper concludes by summarizing existing work and general possibilities regarding the parallelization of evolution strategies and evolutionary algorithms in general.  相似文献

This paper deals with techniques for obtaining random point samples from spatial databases. We seek random points from a continuous domain (usually 2) which satisfy a spatial predicate that is represented in the database as a collection of polygons. Several applications of spatial sampling (e.g. environmental monitoring, agronomy, forestry, etc) are described. Sampling problems are characterized in terms of two key parameters: coverage (selectivity), and expected stabbing number (overlap). We discuss two fundamental approaches to sampling with spatial predicates, depending on whether we sample first or evaluate the predicate first. The approaches are described in the context of both quadtrees and R-trees, detailing the sample first, acceptance/rejection tree, and partial area tree algorithms. A sequential algorithm, the one-pass spatial reservoir algorithm is also described. The relative performance of the various sampling algorithms is compared and choice of preferred algorithms is suggested. We conclude with a short discussion of possible extensions.  相似文献

Whilst much is written about the theory of long range planning it is a fact that unfortunately, the organization of long range planning of business strategy within companies, has not proved to be an attractive object of research for business theorists. This paper is the exception. By an examination of more than 200 companies residing in the Federal Republic of Germany, long range planning is shown to be gaining more importance as a tool for company management. The organizational design of the planning system and its integration into the overall company structure is, according to this analysis, shown to be one of the most central problems of the implementation of corporate planning systems. This paper presents a theoretical framework and the empirical findings on structural and procedural aspects of long range planning, systems. The empirical study was carried out by means of interviews and a questionnaire survey. The survey results show some interesting and important features of the problems engendered by corporate planning and some of the advantages accruing from its successful implementation. Additionally, the analysis provides an interesting backcloth against which to view the implementation of planning and the relationships between the different levels of planning.  相似文献
