Professional evaluators are often called upon to analyze data produced by a catastrophically inadequate evaluation design. This problem is occurring more frequently as accountability pressures force program experts into evaluation activities for which they are not trained. A remedial strategy involving diagnosis of error, application of a corrective procedure and sensitization of program personnel of the need for a more sophisticated stance, is proposed as a solution. A case study is described and the contribution of a remedial strategy to improved evaluation is outlined.  相似文献

关于建立我国住房储蓄银行的探讨   总被引:2,自引:0,他引:2

据资料显示,1998年底在北京设立代表处的德国最大住房储蓄银行———施威比豪尔银行,于2001年与中国建设银行签署了合作协议,将在天津市建立中国第一家真正意义上的、专门服务于买房者的合资住房储蓄银行。这对于刚刚起步而且已经加入WTO的中国住房金融业来说,既是机遇,又是挑战。外资住房银行的进入,不但为国内提供了住房金融业发展所需的大量资金,而且还带来了先进的业务操作技术和成功的管理经验,有利于中国住房金融业的快速发展和完善。但是,我们还应看到,合资住房储蓄银行的建立,不可避免地会冲击本来就发展滞后…  相似文献

发达国家中的大国与小国的和谐建设路径是不同的.大国可谓是中心城市的文明和谐的集聚与扩散,而小国则基本上是城乡一体的运动推进.一般来说,大国在现代文明和谐社会建设中的突出特征是:它在自己经济社会的全面发展中,集聚起庞大的城市文明,并通过城市的拉力和乡村的推力作用,把乡村中的各路精英转入城市,集聚起社会财富的同时,也把乡村中的穷人和大量的矛盾与社会的不和谐带入了城市.  相似文献

This paper introduces a novel approach for modeling a set of directed, binary networks in the context of cognitive social structures (CSSs) data. We adopt a relativist approach in which no assumption is made about the existence of an underlying true network. More specifically, we rely on a generalized linear model that incorporates a bilinear structure to model transitivity effects within networks, and a hierarchical specification on the bilinear effects to borrow information across networks. This is a spatial model, in which the perception of each individual about the strength of the relationships can be explained by the perceived position of the actors (themselves and others) on a latent social space. A key goal of the model is to provide a mechanism to formally assess the agreement between each actors’ perception of their own social roles with that of the rest of the group. Our experiments with both real and simulated data show that the capabilities of our model are comparable with or, even superior to, other models for CSS data reported in the literature.  相似文献

Recently there has been a surge in the availability of online data concerning the connections between people, and these online data are now widely used to map the social structure of communities. There has been little research, however, on how these new types of relational data correspond to classical measures of social networks. To fill this gap, we contrast the structure of an email network with the underlying friendship, communication, and advice seeking networks. Our study is an explorative case study of a bank, and our data contains emails among employees and a survey of the ego networks of the employees. Through calculating correlations with QAP standard errors and estimating exponential random graph (ERG) models, we find that although the email network is related to the survey-based social networks, email networks are also significantly different: while off-line social networks are strongly shaped by gender, tenure, and hierarchical boundaries, the role of these boundaries are much weaker in the email network.  相似文献

Insufficient attention has been paid to whether disclosure rates of sensitive or stigmatizing information vary as a function of method of inquiry. Methods vary both in terms of the anonymity afforded the participant and the opportunity to make a connection with the researcher, both of which might affect participants' willingness to disclose such information. In this investigation, 215 undergraduate students were randomly assigned to complete identical questionnaires using one of the three most common methods of data collection (in-person interview, telephone interview, and paper-and-pencil questionnaire) or an automated telephonic data collection (ATDC) system. Questions on six topic areas of increasing social sensitivity (study habits, substance use, physical and sexual aggression, victimization and perpetration) were included. The results indicated that there were no differences in disclosure rates due to methods and no method by topic interaction, but the two telephonic methods both produced significantly higher participation rates than the two other methods. The results suggest that, at least for a college student sample, an automated telephonic system produces data comparable to that of more traditional methods, while offering greater convenience, economy, and participation.  相似文献

Abstract

This study consisted of analyzing several hypotheses derived from Tajfel and Turner's social identity theory (Tajfel and Turner, 1979) within a real-life situation. We identified the intergroup relations among three banks in Brazil as an ideal chance to test the salience hypothesis (Oakes & Turner, 1980; Doise & Sinclair, 1973) and also the relationship between discrimination and social identity (Brown et al. 1983b). In general, results did not support the hypotheses, and alternative explanations of results, in terms of the groups ' real life conditions, are discussed.  相似文献

The primus inter pares of the UN-approved Millennium Development Goals is to reduce poverty. The only internationally accepted method of estimating poverty requires a measurement of total consumption based on a time-consuming and resource-demanding measure of household expenditure in an integrated survey over 12 months. Rather than measuring poverty, say, only every fifth year, a model is presented to predict poverty based on a small set of household variables to be collected annually between two 12-monthly household surveys. Information obtained from these “light” surveys might then be used to predict poverty rates. The key question is whether the inaccuracy in these predictions is acceptable. It is recommended that these models be tested at a country level and if the test results are similar to those found here, that this approach be adopted.   相似文献

The need for construction resource planning to avoid non-completion of, or delays to, projects and potential damage to an economy by trying to undertake programmes for which resources are not available is stressed. Then the availability, and method of application, of data for national use is considered followed by the problems of transferability of data from one country to another. Examples are given of the range of data for a specific country, of the broad labour inputs to construction for a number of countries of different characteristics and of key material requirements for twenty categories of housing over eight countries. The conclusion is that it is now possible to undertake resource planning for any major project or development plan anywhere in the world, though refinement of the available data and an increase in the volume of data is desirable. The authors suggest that a focal point for the collection of data and a clearing house for its use be established.  相似文献

Recent advances in handheld computer hardware and software may provide alternatives to paper-based data collection methods. The authors compared data collected with paper forms to data collected with handheld computer-based forms in a field observation study of alcohol purchase attempts at 47 community festivals in a large metropolitan area. Agreement between data collected with paper forms and data collected with handheld computers was greater than 95%. Computer-based forms handled branching patterns better and yielded data that were immediately available for analyses. Paper forms handled written comments better. Handheld computers are a feasible alternative to paper forms for field data collection.  相似文献

This paper analyses the way in which a particular newspaper report constructs ‘public opinion’ based on data from small‐scale qualitative research. Using as a case study a report of a focus group discussion of Clinton's grand jury testimony, we show how these data are ‘worked up’ as representative, generalisable, and valid. By capitalising on the advantages of focus group data, while attending to and countering their disadvantages, the newspaper report is able to suggest that the views of ten people in San Francisco offer an authoritative indication of public opinion about Clinton across the USA. Finally, we sketch out some of the implications of this case study in relation to the construction of facticity more generally.  相似文献

The social sciences have achieved highly sophisticated methods for data collection and analysis, leading to increased control and tractability of scientific results. Meanwhile, methods for systematizing these results, as well as new ideas and hypotheses, into sociological theories have seen little progress, leaving most sociological arguments ambiguous and difficult to handle, and impairing cumulative theory development. Sociological theory, containing many valuable ideas and insights, deserves better than this. As a way out of the doldrums, this paper presents a systematic approach to computer–supported logical formalization, that is widely applicable to sociological theory and other declarative discourse. By increasing rigor and precision of sociological arguments, they become better accessible to critical investigation, thereby raising scientific debate to a new level. The merits of this approach are demonstrated by applying it to an actual fragment from the sociological literature.  相似文献
