Mathematical theory of voting and social choice has attracted much attention. In the general setting one can view social choice
as a method of aggregating individual, often conflicting preferences and making a choice that is the best compromise. How
preferences are expressed and what is the “best compromise” varies and heavily depends on a particular situation.
The method we propose in this paper depends on expressing individual preferences of voters and specifying properties of the
resulting ranking by means of first-order formulas. Then, as a technical tool, we use methods of second-order quantifier elimination
to analyze and compute results of voting. We show how to specify voting, how to compute resulting rankings and how to verify
voting protocols. 相似文献

Deep orthographies usually represent morphology and phonology simultaneously; both resources are necessary for spelling. In shallow orthographies, such as Spanish, phonology would be enough to spell most words. However, morphological knowledge may also take part in spelling. This study examined how Spanish children in 1st (N = 148), 2nd (N = 155) and 3rd grade (N = 155) use morphological information to spell plural nouns and verbs. A word dictation task was designed. The task included high and low frequency plural nouns ending in “s” (morphological “-s” condition) and verbs in the 2nd person ending in “s” (morphological “-s” condition). A lexical condition including words with a final “s” which was not morphologically motivated was used as a control condition (lexical “-s” condition). The results show that, although Spanish spelling is influenced by phonology, morphological information is also used. These results are discussed in relation to current models of word spelling. 相似文献

Among the provisions of the recently signed Garrett Lee Smith Memorial Act, Congress called for the use of screening to detect adolescents who are at risk for suicide. After a review of the literature, 17 studies involving screening instruments and programs were identified. We addressed the question: What do we know about the demonstrated effectiveness and safety of screening as a tool or program to prevent suicide among adolescents? While youth suicide screening programs offer the promise of improving identification for those who need treatment the most, further research is essential to understand how, when, where, and for whom screening programs can be used effectively and efficiently. 相似文献

Many proposals from the analysis of social networks focused on the study of scientific collaboration have been made recently. The Small Worlds theory seems to be the most efficient to study the inner features of the scientific community. Those researches have demonstrated that small communities are based on some key individuals who connect some groups which, on the contrary, would be disconnected. One of the disadvantages from the perspective of the analysis of networks is the lack of researches of particular nodes. With the implementation of a pseudocode algorithm of Floyd, we try to avoid this. To study how a small community is formed and, as a research of one case, we observe the invisible college which is formed when connecting the fifteen most productive authors of the Journal of Personality and Social Psychology . 相似文献

The aim of this study was to examine the moderating role of emotional awareness in the relationship between emotion regulation strategies and emotional information processing. A total of 120 female students regulated emotions while watching an unpleasant film. Before and after emotion induction, participants completed a set of tasks that required matching facial expressions. The results demonstrated that participants who were high in emotional awareness showed a significantly smaller increase in error responses (i.e., incorrect matches) than participants who were low in emotional awareness. However, this effect was observed only in suppression (i.e., inhibition of an emotionally expressive behavior), masking (i.e., emotion experienced with a happy expression) and control (i.e., no regulation) conditions. Among reappraisers, who were instructed to adopt a neutral attitude toward the film, regardless of whether they were high or low in emotional awareness, there was not a significant increase in error responses. This study shows that the potentially damaging impact of negative emotions on the processing of emotional information can be prevented by a high emotional awareness or with the implementation of reappraisal as an emotion regulation strategy. 相似文献

More than 100 years ago, Huey (1908/1968) indicated that the upper part of words was more relevant for perception than the lower part. Here we examined whether mutilated words, in their upper/lower portions (e.g., ), can automatically access their word units in the mental lexicon. To that end, we conducted four masked repetition priming experiments with the lexical decision task. Results showed that mutilated primes produced a sizeable masked repetition priming effect. Furthermore, the magnitude of the masked repetition priming effect was greater when the upper part of the primes was preserved than when the lower portion was preserved-this was the case not only when the mutilated words were presented in lower case but also when the mutilated words were presented in upper case. Taken together, these findings suggest that the front-end of computational models of visual-word recognition should be modified to provide a more realistic account at the level of letter features. 相似文献

The general purpose of this work is to analyze the overlap between organizational identification and commitment. Specifically, our study focuses on the analysis of the differences and similarities between sense of belonging (a dimension of organizational identification) and affective commitment (a dimension of organizational commitment). In order to do this, we analyzed their discriminant validity and raised their relationship with variables that previous research had showed like precedent and subsequent variables of them: value congruence, perceived support, organizational citizenship behavior, and intention to continue in the organization. A total of 292 people at one organization completed surveys measuring the variables previously described. The results showed that sense of belonging and affective commitment are different concepts and they have different relationships with relation to precedent and subsequent variables. Affective commitment seems to be more useful than sense of belonging to predict organizational citizenship behavior aimed at the organization and intention to continue. Some practical implications are described. 相似文献
