Constructing Finite Least Kripke Models for Positive Logic Programs in Serial Regular Grammar Logics
A serial context-free grammar logic is a normal multimodal logicL characterized by the seriality axioms and a set of inclusionaxioms of the form ts1...sk. Such an inclusion axiom correspondsto the grammar rule t s1... sk. Thus the inclusion axioms ofL capture a context-free grammar . If for every modal index t, the set of words derivable fromt using is a regular language, then L is a serial regular grammar logic. In this paper, we present an algorithm that, given a positivemultimodal logic program P and a set of finite automata specifyinga serial regular grammar logic L, constructs a finite leastL-model of P. (A model M is less than or equal to model M' iffor every positive formula , if M then M' .) A least L-modelM of P has the property that for every positive formula , P iff M . The algorithm runs in exponential time and returnsa model with size 2O(n3). We give examples of P and L, for bothof the case when L is fixed or P is fixed, such that every finiteleast L-model of P must have size 2(n). We also prove that ifG is a context-free grammar and L is the serial grammar logiccorresponding to G then there exists a finite least L-modelof s p iff the set of words derivable from s using G is a regularlanguage. 相似文献

- This study empirically investigates the impacts of consumer ethnocentrism and cultural sensitivity on both imported product judgment and intention to purchase local products in the context of a developing country—Vietnam. Structural equation modeling was used to test these impacts, utilizing a sample of 549 consumers. The results show that consumer ethnocentrism is negatively related to imported product judgment and positively related to intention to purchase local products. In addition, cultural sensitivity has a positive relationship with imported product judgment but not with consumer ethnocentrism. The results also indicate that the impacts of consumer ethnocentrism on imported product judgment and on intention to purchase local products are not different in terms of product categories, gender, income, and education levels. However, differences exist between younger and older consumers.

Low self‐esteem appears to be both a vulnerability factor for cardiac diseases and a result of cardiac diseases. Thus enhancing self‐esteem might facilitate recovery and/or help to prevent recurrence. Since some evidence suggests that self‐esteem might even serve as an important gauge of cardiac rehabilitation, it is therefore important to know more of the construct of self‐esteem to enable the planning of a more promising rehabilitation process. This paper explores the source and basis of the self‐esteem of Hong Kong Chinese with cardiac diseases. One hundred and fifty‐two adults with cardiac diseases and 146 adults not suffering from any major illness participated in this study. The Adult Source of Self‐Esteem Inventory (ASSEI) (Elovson & Fleming, 1989), open‐ended questions on self‐evaluation, and interviewing were the major procedures used to identify the sources and basis of the self‐esteem of persons with and without cardiac diseases. The subjects' important life aspects were identified through interpreting their responses to open‐ended questions and interviews. Moreover, a structured questionnaire on their subjective perceptions of importance and satisfaction in different life areas was used to identify the relationships between discrete self‐concept variables. Factor analysis of their responses to the 20 ASSEI items revealed four factors, namely, Interpersonal Relationship, Personal Quality, Physical Self, and Personal Achievement. We also examined and compared the means and ranks of the ASSEI items as indicated by the subjects. Content analysis of open‐ended questions further confirmed the self‐esteem domains of persons with cardiac diseases. The discrepancy of ideal‐actual physical abilities was found to be more prominent in the cardiac group. It was also found that family is an important entity to Chinese individuals with cardiac diseases. Implications of the findings to rehabilitation of persons with cardiac diseases were also discussed. 相似文献

Factors affecting ethnic identity and other group orientation were assessed in 115 college students from 5 ethnic groups. Ethnic group self‐identification, negative and positive interracial experiences, perceptions of racial bias, social support, just‐world beliefs, and psychological distress were each associated with various components of ethnic identity and are discussed within a counseling perspective. Los factures que afectan la identidad étnica y otras orientaciónes hacia grupos fueron evaluados en 115 estudiantes colegiales de 5 grupos étnicos. La identificación de grupo etnico propio, las experiencias interraciales negativas y positivas, las percepciones del prejuicio racial, apoyo social, creencias en un mundo justo, y la afflicción psicológica fueron asociadas con varios componentes de la identidad étnica y son discutidos dentro de la perspectiva de la consejería. 相似文献

Two Kinds of Mental Realism 总被引:1,自引:0,他引:1
Tamás Demeter 《Journal for General Philosophy of Science》2009,40(1):59-71
I argue that there is a distinction to be drawn between two kinds of mental realism, and I draw some lessons for the realism-antirealism
debate. Although it is already at hand, the distinction has not yet been drawn clearly. The difference to be shown consists
in what realism is about: it may be either about the interpretation of folk psychology, or the ontology of mental entities.
I specify the commitment to the fact-stating character of the discourse as the central component of realism about folk psychology,
and from this I separate realism about mental entities as an ontological commitment towards them. I point out that the two
views are mutually independent, which provides the possibility of considering folk psychology as not being in cognitive competition
with scientific psychology. At the end I make a tentative suggestion as to how to interpret the former in order to avoid this
conflict. 相似文献

Asystematic study of the linkages between gender issues and parenting is made among Chinese families. This study examines sex differences in parenting attributes across fathers and mothers and towards sons and daughters, and compares the contributions of fathers and mothers to the prediction of academic performance across boys and girls. Four parenting attributes are included: nurturance, psychological control, parental involvement in education, and parental academic efficacy. Data were collected from 461 Chinese father-mother-child triads of children studying Grade 3 to 5 in Hong Kong. Findings of this study, based on multivariate analysis of variance, showed that parental roles followed traditional Chinese cultural expectations. Compared to the fathers, Chinese mothers of school-age children in Hong Kong were more loving and caring, more involved in children's education, and more efficacious in promoting children's academic performance. Results of hierarchical regression analysis examining the role of child's sex as a moderator showed cross-sex influence in parental contribution to academic performance with respect to parental psychological control and academic efficacy. Specifically, boys benefited more from maternal efficacy than girls did and they were also more hampered by mothers with high psychological control, while girls' academic performance was more enhanced by paternal academic efficacy than boys. A gender-balance approach that highlights the significance of gender in moderating parental contributions to academic performance was thus supported. Future research should continue to focus on psychological control and domain-specific parental attributes as potential sources of gender-linked parent-child associations. Investigations should also explore other cognitive and noncognitive domains of child outcome, different child age groups, as well as Chinese populations in various geographical regions. 相似文献

We examined effects of binocular occlusion, binocular camouflage, and vergence-induced disparity cues on the perceived depth between two objects when two stimuli are presented to one eye and a single stimulus to the other (Wheatstone-Panum limiting case). The perceived order and magnitude of the depth were examined in two experimental conditions: (1) The stimulus was presented on the temporal side (occlusion condition) and (2) the nasal side (camouflage condition) of the stimulus pair on one retina so as to fuse with the single stimulus on the other retina. In both conditions, the separation between the stimulus pair presented to one eye was systematically varied. Experiment 1, with 16 observers, showed that the fused object was seen in front of the nonfused object in the occlusion condition and was seen at the same distance as the nonfused object in the camouflage condition. The perceived depth between the two objects was constant and did not depend on the separation of the stimulus pair presented to one eye. Experiment 2, with 45 observers, showed that the disparity induced by vergence mainly determined the perceived depth, and the depth magnitude increased as the separation of the stimulus pair was made wider. The results suggest that (1) occlusion provides depth-order information but not depth-magnitude information, (2) camouflage provides neither depth-order nor depth-magnitude information, and (3) vergence-induced disparity provides both order and magnitude information. 相似文献

In this paper, I introduce a prominent classical scholar, József Balogh, whose work can be read as a significant contribution to the historiography of ancient, and in some sense modern, philosophy. Following a summary biography, I sketch the relevance of Balogh's interpretation of Augustine. I draw some analogies between his and Eric Havelock's treatment of the problems in ancient philosophy, and argue that the obvious similarities between them have a common origin, namely the perspective of the orality/literacy chasm which both treated, in connection with their research into Augustine and Plato, as crucial. Subsequently, I show how the problem of reading aloud, which Balogh was the first to treat systematically, has acquired significance in some current debates in philosophy. 相似文献
