In the Design for All Approach (DfA), an important phase of the design process consists in the individuation of the so-called "limit users", that are that particular group of people with the most "critical" features for the autonomous fruition of a system or a product. Generally, however, it is not easy to identify them in a complete and objective way. A clear and complete outline of design requirements with respect to the "normal" use of a service, product or environment, moreover, is of fundamental importance in inclusive design. In fact, we know how bad design, that doesn't take in account the true "strategies of use", may lead to situations of handicap, also serious, temporary or permanent, regardless if the user is a "disabled" person or not. In relation to this scenario, the paper shows the results of a research which has developed the "Ability/Difficulty Table" ("A/D Table"), a new tool useful to identify the so-called "limit users" and their needs with respect to different activities, linking the main "difficulties", expressed by people, with the "abilities" required to carry out in autonomy the investigated activity. 相似文献

Prior research on Mexican migration has shown that social networks and economic incentives play an important role in determining migration outcomes. We use experimental data from PROGRESA, Mexico's primary poverty-reduction program, to evaluate the effects of conditional cash transfers on migration both domestically and to the United States. Our study complements a growing body of literature aimed at overcoming longstanding hurdles to the establishment of causal validity in empirical studies of migration. Analysis based on the data collected before and after the program's onset shows that conditional transfers reduce U.S. migration but not domestic migration. The data also enable us to explore the role of existing family and community migration networks. The results show that migration networks strongly influence migration, but that the effect of conditional transfers on migration is apparently not mediated by existing migration network structures. Our results suggest that conditional transfers may be helpful in managing rural out-migration, particularly to the United States. 相似文献

This paper compares four cases and explores the effects on network performance of network governance, coordination mechanisms, and the abilities of the network manager. The focus is on shared-governance networks, which are in general considered to have difficulties achieving high-level performances. The cross-case comparison suggests a relationship between coordination mechanisms and the way shared-governance networks are managed: in order to be successful, they must be able to rely on formalized mechanisms and make a pool of “network administrators” responsible for their governance. 相似文献

This essay compares the logic of states and the logic of markets in the management of cultural diversity. On the one hand, the economic logic of markets leads to an encouragement of a 'soft' cultural diversity associated with the marketing of exoticism in music, the arts and cuisine, for example. On the other hand, the liberal states are trapped between their willingness to recognize some form of diversity and their fear of seeing social cohesion harmed by this recognition. In other words, the essay applies Hollified's hypothesis about the liberal paradox in immigration policy to the sphere of cultural diversity in post-immigration situations. 相似文献

The present study was designed to assess the contribution of general features of gross body movements to the attribution of emotions. Eighty-five adult subjects were shown ninety-six videotaped body movements, performed by three actors. Each movement was determined by seven general dimensions: trunk movement, arm movement, vertical direction, sagittal direction, force, velocity and directness. Using rating scales, the subjects judged the compatibility of each movement with each of twelve emotion categories. The results showed which movement features predicted particular ratings. Emotion categories differed as to the amount, type, and weights of predicting movement features. Three factors were extracted from the original ratings and interpreted as Rejection-Acceptance, Withdrawal-Approach, and Preparation-Defeatedness.I wish to thank Jacques van Meel for his stimulating contribution to this study, and the reviewers for their comments on earlier drafts of the final report. 相似文献

The audit fees available since 2005 as a consequence of the Bilanzrechtsreformgesetz (commercial code reform act) show an extremely high supplier concentration on the German audit market of publicly listed companies. This justifies the assumption of audit fees above perfect market equilibrium prices. However, the complete collection and multivariate regression analysis of all relevant audit fee and client data document a 24 % decrease in audit fees in 2005 and an average 15 % decrease in the two subsequent years due to auditor changes. This can be interpreted as an indicator for price competition. In addition, the audit fee data shows that the audit fee decreases are only partially compensated by subsequent increases. As a consequence, there is no evidence for lowballing at present. Further time series are necessary to show if the current trend is sustainable. 相似文献

Several important economic time series are recorded on a particular day every week. Seasonal adjustment of such series is difficult because the number of weeks varies between 52 and 53 and the position of the recording day changes from year to year. In addition certain festivals, most notably Easter, take place at different times according to the year. This article presents a solution to problems of this kind by setting up a structural time series model that allows the seasonal pattern to evolve over time and enables trend extraction and seasonal adjustment to be carried out by means of state-space filtering and smoothing algorithms. The method is illustrated with a Bank of England series on the money supply. 相似文献
