Infants in laboratory settings look longer at events that violate their expectations, learn better about objects that behave unexpectedly, and match utterances to the objects that likely elicited them. The paradigms revealing these behaviors have become cornerstones of research on preverbal cognition. However, little is known about whether these canonical behaviors are observed outside laboratory settings. Here, we describe a series of online protocols that replicate classic laboratory findings, detailing our methods throughout. In Experiment 1a, 15-month-old infants (N = 24) looked longer at an online support event culminating in an Unexpected outcome (i.e., appearing to defy gravity) than an Expected outcome. Infants did not, however, show the same success with an online solidity event. In Experiment 1b, 15-month-old infants (N = 24) showed surprise-induced learning following online events—they were better able to learn a novel object's label when the object had behaved unexpectedly compared to when it behaved expectedly. Finally, in Experiment 2, 16-month-old infants (N = 20) who heard a valenced utterance (“Yum!”) showed preferential looking to the object most likely to have generated that utterance. Together, these results suggest that, with some adjustments, online testing is a feasible and promising approach for infant cognition research.  相似文献

During the last 2 decades the public administration and the public services have undergone far-reaching transformations that resulted in substantial changes in work and employment. This contribution discusses the question as to how workers perceive these upheavals and what consequences these have for their occupational identity. Based on empirical research on an Austrian town the authors show how local government employees, doctors and nurses at the community hospital and the post office’s deliverers and counter clerks interpret the transformations in particular from the perspective of their occupational self-conception. The article makes clear that using the concept of a threefold relationship to work makes it easier to understand workers’ perceptions, interpretations and reactions. Such a threefold relationship to work includes a labour power perspective, a subject perspective and the public sector ethos.  相似文献

A European Social Survey (ESS)—based study of Clark and Lelkes on the European level showed a double positive connection between religion and life-satisfaction: not only did a personal involvement have a positive impact, but there was also a regional externality. Even atheists seemed to be happier in areas with many religious people. However, the regional structure of the ESS can be seen as methodologically doubtful. We therefore replicated the study with more rich German data. In our study we confirm the positive individual effect of religion, but we did find a negative regional externality. However, further analysis revealed, this was an effect of an omitted variable: the degree of urbanization. In a more detailed approach we show that this effect is confined to areas with a protestant majority. We conclude that the positive degree of urbanization influence on life-satisfaction is presumably due to the chance for more political participation in the (protestant) city states in Germany.  相似文献

This article first reviews how the concept of privatisation has been referred to in the current restructuring of the social housing system, especially in the case of the UK. The term 'privatisation' is then examined in greater detail and its wider meaning is discussed. By using the network approach, privatisation in relation to housing can be understood in terms of the changing combinations of agents involved in providing social housing, which gives rise to the commodified impact on the distribution of social housing. By using the privatisation process of social housing in Taiwan as an example, three distinct combinations in terms of providing social housing are identified. With an increasing number of social housing units being provided by the marketised social housing model where private agents control the process of providing social housing, along with more market rules being involved in the provision and the partial removal of means tests in relation to the distribution of social housing, the privatisation of social housing development in Taiwan is having a major impact on equity.  相似文献

The logic of preference reconsidered   总被引:4,自引:0,他引:4  
Preferences are an important object of study in economic theory. Their logico-mathematical study has become prominent with the raise of modern decision theory and with the new conceptions of utility-functions and personalistic probabilities. The ‘basic logic’ at the foundation of the more advanced theories of preference, however, has been relatively little investigated. The pioneer work is Hallden's The Logic of ‘Better’ of the year 1957, followed by von Wright's The Logic of Preference in 1963. The topic has turned out unexpectedly problematic and there is as yet little consensus among logicians about the basic laws of preferring. A reason for this is apparently that there exist several concepts of preference which must be disentangled and kept apart in a logical theory. How this is to be done is discussed in the introductory sections (1–5) of the present paper. In Section 8 is sketched a logic for an asymmetric and connected preference-relation which holds between ‘possible worlds’ within a subject's ‘preference-horizon’ (Section 7). Preferences between states of affairs generally are called holistic when they hold ceteris paribus, i.e., when there is a corresponding preference-relation between any pairs of possible worlds which differ only in those two states and in no others. (Section 6.) Holistic preferences between states are asymmetrical and transitive but they do not form a linear preference order. (Section 9.) Failure to notice this, the author maintains, is responsible for much confusion in the traditional treatment of the subject. In the concluding sections (10–12) the author discusses the mutual relations of the value-absolutes, the good and the bad. Can they be defined in the terms of the relative notion of betterness or preference (and logical constants) alone? The definition which says that the goodness of a state is the holistic preference of it over its contradictory, answers the question affirmatively but conflicts with several deep-rooted axiological intuitions of ours. A more satisfying definition of the value-absolutes requires the additional notion of a value-less state (world) with which all the other states may be compared. In this connection some ideas of G. E. Moore about the notion of an ‘empty’ world can be interestingly exploited.  相似文献

This article examines the relationship between personal discount rates and sexual behaviors in a sample of teenagers and young adults. We find that higher discount rates (an indication of less willingness to forego current consumption for future consumption) are significantly associated with a range of sexual behaviors, including ever having sex, having sex before age 16 years, and past or current pregnancy. These associations are consistent with previous studies showing a link between discounting and other, non-sexual health behaviors. JEL Classification D80 · D90 · I10  相似文献

After defining the complementary relation R of a binary relation R on a set X, this paper constructs the binary relation C (is a complementary property of) on the set P of nine well known elementary properties that R might possess. It deduces some theorems about C; especially that symmetry is the only one of these possible properties of R on X that is possessed by C on P. The set P may be enlarged to contain other elementary properties of R on X without changing the truth of these theorems, when the symbols of sets are properly modified. Finally, the paper discusses the desirability of a general theory of elementary properties of binary relations for the further development of statistical decision theory.  相似文献

Risk and its Management in Post-Financial Crisis Hong Kong   总被引:1,自引:0,他引:1  
In the 1970s and up until the financial crisis occurred in the late 1990s, Hong Kong prospered in a relatively stable social, economic and political context. Since the financial crisis, however, its population has been increasingly exposed to risk: there has been job uncertainty and decreasing capacity for self‐reliance, leading to a growing reliance on public welfare and on families at a time when both are under pressure. The old welfare policies, unable to cope with the new risks, have been replaced by neo‐liberal reforms, redistributing the roles and responsibilities of the individual and the state, with a greater burden falling on the former. Individuals are required to be prudent to manage risk. While these reforms have relieved some of the burden on the state, both new social risk groups and ‘net taxpayers’ considered themselves to have borne disproportional costs. Society is facing serious problems resulting from ineffective old welfare policies, new social risks due to new policies, and the political upheavals arising from increased social conflicts and weakened social cohesion and solidarity. A further complication is that there is no acceptable platform or agent to negotiate a compromise between the polarized groups. This article argues that reliance on publicly funded risk coping strategies or on neo‐liberal risk prevention and mitigation strategies is not a desirable and sustainable policy. A commonly accepted political platform is required to negotiate a compromise which emphasizes shared and balanced roles and responsibilities, and a well‐conceived combination of risk prevention, mitigation and coping strategies.  相似文献
