We obtain in this paper a representation of the formulae of extensions ofL
by generalized quantifiers through functors between categories of first-order structures and partial isomorphisms. The main tool in the proofs is the back-and-forth technique. As a corollary we obtain the Caicedo's version of Fraïssés theorem characterizing elementary equivalence for such languages. We also discuss informally some geometrical interpretations of our results. 相似文献

How did a new science initially promoted by only a few individuals eventually become a widespread cultural phenomenon practiced and known by thousands of people? Following a transnational approach, this article traces the introduction of psychical research into China during the first two decades of the 20th century. Known in the Republican period (1912–1949) as Spiritual Science (xinling kexue or xinling yanjiu), psychical research flourished between the 1920s and 1930s, playing a key role in the popularization of applied psychology and mind-cure across China. This article takes a step back from the heyday of Spiritual Science by looking at the period that immediately preceded and helped define it. Focused on wide-circulation newspapers, popular manuals, and stage performances, it teases out the ways in which Chinese popular culture translated European, American, and Japanese psychical research to local Chinese audiences in the midst of China's search for modernity. By naturalizing the reality of psychic powers, spiritual scientists blurred the boundaries between science and superstition in a period when these were posited as diametrically opposed. 相似文献

The consistency between letters and sounds varies across languages. These differences have been proposed to be associated with different reading mechanisms (lexical vs. phonological), processing grain sizes (coarse vs. fine) and attentional windows (whole words vs. individual letters). This study aimed to extend this idea to writing to dictation. For that purpose, we evaluated whether the use of different types of processing has a differential impact on local windowing attention: phonological (local) processing in a transparent language (Spanish) and lexical (global) processing of an opaque language (English). Spanish and English monolinguals (Experiment 1) and Spanish–English bilinguals (Experiment 2) performed a writing to dictation task followed by a global–local task. The first key performance showed a critical dissociation between languages: the response times (RTs) from the Spanish writing to dictation task was modulated by word length, whereas the RTs from the English writing to dictation task was modulated by word frequency and age of acquisition, as evidence that language transparency biases processing towards phonological or lexical strategies. In addition, after a Spanish task, participants more efficiently processed local information, which resulted in both the benefit of global congruent information and the reduced cost of incongruent global information. Additionally, the results showed that bilinguals adapt their attentional processing depending on the orthographic transparency. 相似文献

The purpose of this study was to evaluate the role of maternal and paternal alcohol consumption as independent risk factors in postneonatal mortality. Questions on the frequency and quantity of alcoholic drinks consumed were included in a questionnaire used as part of a case-control study. Over a period of 11 months the families of 157 cases and 468 controls, matched for age and locality, were interviewed. Odds ratios and 95% confidence intervals were obtained by matched univariate analysis and by multiple conditional logistic regression. Maternal consumption during pregnancy, maternal consumption during breastfeeding and maternal consumption in the past year were not risk factors for postneonatal mortality. A multiple matched analysis did not alter these results. Matched univariate analysis of paternal alcohol consumption gave several positive results, including variables pertaining to the father's consumption in a multiple logistic regression model with traditional risk factors, which revealed that the frequency of paternal consumption in the last year, as estimated by the mother, was found to have a significant effect on postneonatal mortality. 相似文献

The present research focused on power processes in a simulated organizational structure consisting of three hierarchical levels occupied by different numbers of mules and females. Subjects were presented with a chart showing the organizational hierarchy of which they were a member placed at the lowest level, and asked to nominate any person for the leader position vacated by the current incumbent. The results of Experiment I (n = 88 Dutch male and female university students) showed that male subjects strongly overnominated themselves, whereas a majority of the female subjects nominated either self or another female. Of the others that were nominated by both males and females, almost all were occupants of positions immediately below the leader position, indicating the normative influence of a bureaucratic rule of leader succession. Experiment 2 was a replicational study carried out in a different culture (n = lOl Polish male and female university students). Polish subjects adhered to the bureaucratic rule more strongly than their Dutch counterparts, and both females and males nominated mostly males. Results are discussed with reference to gender self-stereotypes and cultural differences. 相似文献

The relationship of locus of control to depression, anxiety, hostility, and physical health was assessed in a sample of multicultural
college students (N = 162). Powerful Others Health Locus of Control was correlated with depression, anxiety, hostility, and
recent physical symptoms while Chance Health Locus of Control (CHLC) was correlated with all of the above as well as chronic
physical symptoms and major health problems. When controlling for a variety of health risk factors (viz., age, sex, body mass,
exercise, smoking, salt, alcohol, and caffeine), only CHLC remained significant in the physical health models. Results support
the cognitive model of mental health which emphasize the importance of adaptive beliefs. Specifically, they suggest that issues
about control are related to negative affect and indicate that the often-cited relationship of an external locus of control
to depression and anxiety also holds for hostility. The findings do not, however, support the view that anxiety and depression
are associated with different types of external locus of control but rather suggest a unified set of locus of control beliefs
underlying the three types of negative affect. In addition, evidence is provided for the external validity of the Multidimensional
Health Locus of Control (MHLC) Scales with respect to mental health. Further, the results indicate that belief about one’s
health may play a significant role in one’s physical health and that the health behavior model of the relationship between
locus of control and physical health is insufficient to explain the relationship. As the Chance and Powerful Others MHLC scales
were not related to health habits in this sample but were related to mental health (viz., depression, anxiety, and hostility),
locus of control beliefs may be related to physical health via their relationship with mental health. 相似文献

In this paper we prove that the category of abelianl-groups is equivalent to the category of perfect MV-algebras. Furthermore, we give a finite equational axiomatization of the variety generated by perfect MV-algebras.Presented byDaniele Mundici 相似文献
