There are reasons to believe that infant‐directed (ID) speech may make language acquisition easier for infants. However, the effects of ID speech on infants' learning remain poorly understood. The experiments reported here assess whether ID speech facilitates word segmentation from fluent speech. One group of infants heard a set of nonsense sentences spoken with intonation contours characteristic of adult‐directed (AD) speech, and the other group heard the same sentences spoken with intonation contours characteristic of ID speech. In both cases, the only cue to word boundaries was the statistical structure of the speech. Infants were able to distinguish words from syllable sequences spanning word boundaries after exposure to ID speech but not after hearing AD speech. These results suggest that ID speech facilitates word segmentation and may be useful for other aspects of language acquisition as well. Issues of direction of preference in preferential listening paradigms are also considered. 相似文献

Taking as a point of departure the postulated political-ideological and fiscal ‘crisis of the welfare state’, this article emphasises recent changes in the relationship between the four sectors of welfare providers: the informal sector of the family or community; the for-profit sector — where social goods are offered by profit-seeking institutions; the formalised sector of voluntary organisations; and the public sector of statutory bodies. Discussion is concentrated on the changing relationship between the voluntary and public sectors. Are voluntary organisations able to cope with new and extensive welfare problems within a more decentralised welfare state? Do they express the values, and do they possess the resources that both governmental agencies and the organisations themselves take for granted? 相似文献

This paper presents the re-analysis of a previouslypublished instrument, based on Bloom's taxonomy,developed to measure the cognitive domain of thequality of life of university students. The items inthis instrument were assessed using Guttman's SmallestSpace Analysis. The findings generally supportBloom's conceptualization, identifying 5 of 6dimensions in the taxonomy: Knowledge, Comprehension,Application, Analysis, and Evaluation. The findingsprovide support for the enduring utility of Bloom'staxonomy, and reinforce the ongoing need to testtheoretically informed instruments using sophisticatedstatistical techniques. 相似文献

Abstract Female assembly workers reporting constant neck and shoulder pain, despite ergonomically acceptable working conditions, were interviewed. As a starting point in the interviews, the patients were asked to describe their general situation at work. Their reports were fed back and discussed with company management in a wider group meeting and resulted in an improvement in their attitudes to those workers. A climate of confidence and well-being was created, which the women experienced as genuine. The workers' report of pains improved dramatically and absence due to musculoskeletal disorders was reduced by more than 90% during the following year. 相似文献

Ethnic and kinship ties have long been viewed as potential catalysts for favoritism, and hence corruption. In experiments conducted in three countries, we recruit siblings, coethnics and strangers and vary the relationship(s) between the players of a game to observe how kin and ethnic ties influence the willingness of two players to benefit one another at the expense of a third party. We see universal sibling favoritism, but ethnic favoritism, and favoritism toward other in-group members (friends) varies. We argue this may be driven in part by kinship institutions, since favoritism is more common in societies with denser kin networks. ( JEL D9, C9, D73, J12) 相似文献

We conduct a contest experiment to study if spread seeking and effort can be managed when participants can invest in increasing both the mean and the spread of an uncertain performance variable. Subjects are treated with different prize schemes and in accordance with theory, we observe higher investments in spread for the winner-take-all scheme. Both types of investments can be controlled with a three-level prize scheme. However, the control management is imperfect and behavior is characterized by inertia. We also explore the correlation between effort and spread across subjects and find that is robustly positive. 相似文献

Seymour B. Sarason, one of the founders of community psychology, has stated the need for developing barometers of community changes. The authors present a methodology for identifying societal ideologies, ideological shifts and power relations as reflected by the language of public discourse. As a case study, systematic analyses of changes in the Norwegian language over the last two decades are presented. It is demonstrated how Norwegian society has been gradually transformed from a traditional Scandinavian welfare society towards the values and ideals of neo-liberalist market ideology: for instance, language reflects and supports competitive practices increasingly being applied to public service provision. Another example is that the public discourse of individual rights has gradually been overshadowing the discourse of community duties and obligations. On the other hand, the analyses also reveal counter-ideologies, reflected, for example, in the launching of new words and expressions critical to neo-liberalist ideology. 相似文献

It has become widely accepted that focusing exclusively on income growth may lead to a too narrow-sighted measure of changes in well-being. People care about other dimensions of life, such as their health, employment, social interactions and personal safety. Moreover, an exclusive focus on income growth remains blind to the distribution of income and well-being in the society. We propose therefore a set of five principles for a richer measure of well-being. In particular, we advocate the use of a measure based on “equivalent incomes”, which satisfies these principles. We discuss and illustrate how this equivalent income approach can be implemented in Europe, using the ESS data for 2008 and 2010. We find that introducing inequality aversion and including other dimensions in the analysis leads to a remarkably different perspective on the growth of well-being in Europe. 相似文献
