Toward model-theoretic modal logics

Adding certain cardinality quantifiers into first-order language will give substantially more expressive languages. Thus, many mathematical concepts beyond first-order logic can be handled. Since basic modal logic can be seen as the bisimular invariant fragment of first-order logic on the level of models, it has no ability to handle modally these mathematical concepts beyond first-order logic. By adding modalities regarding the cardinalities of successor states, we can, in principle, investigate modal logics of all cardinalities. Thus ways of exploring model-theoretic logics can be transferred to modal logics.     

启动情绪和呈现方式对错误记忆的影响

采用DRM范式(Deese-Roediger-Mc Dermott paradigm),考察了启动情绪状态下词表项目的呈现方式对错误记忆的影响。结果发现:(1)启动情绪主效应不显著。(2)词表项目的呈现方式主效应显著。(3)启动情绪与呈现方式间存在交互作用。在愉快启动情绪状态下分组呈现的错误再认率明显高于随机呈现条件;当词表项目分组呈现时,三种情绪状态下的错误再认率有显著差异,其中愉快启动情绪下的错误再认率最高,其次是悲伤情绪,最低的为对照组—非启动情绪状态。说明启动的愉快情绪增强了对关键诱饵的连续激活累积效应,从而导致对关键诱饵较高的错误再认率。     

The performance of school integration according to the perception of specialist teachers in therapeutic pedagogy

The main purpose of this article is to analyse the perception that specialist teachers in therapeutic pedagogy have of the integration of students with specific needs for educational support. Diverse groups of students are differentiated. More specifically, it aims to know how teachers perceive students' performance and participation, and also certain attitudes towards the students (acceptance, involvement of fellow students…). Teachers' opinions of various measures to improve integration are also analysed as are the diverse preferred means of schooling and support. For this purpose, a 114-item Lickert-type questionnaire, with 8 additional personal identification items, was used. The sample comprised 106 specialist teachers who work in Asturias, out of an entire sample of 406. The results reveal that specialist teachers do not perceive the same attitudes in the different groups studied. Students with behaviour disorders are the most rejected and the ones from whom teachers can expect the least. The group of ethnic minorities needs to improve family involvement. The specialists demand more human and physical resources and most of them think that ordinary centres provide the most suitable form of schooling.     

Spinal cord injured people: differences in psychological variables from a gender perspective

This ex post factor study is within the framework of studies dealing with the psychological aspects involved in the rehabilitation of people with physical handicaps from the perspective of gender. From this perspective, the study focuses on comparing and studying the differences between men and women using the EMELM Scale (Multidimensional Evaluative Scale for People with Spinal Cord Injury). Participants were 143 people -99 men and 44 women- with spinal cord injuries. The results showed no differences as a result of gender in any of the following psychological variables related to the spinal cord injury adjustment process: extraversion-neuroticism, motivation and anxiety, locus of control, current coping strategies, remembrance of coping strategies and depression. The implications of these results for future research are discussed.     

Relationship between productivity and efficiency in research funding for Spanish regions

Quality is a major current needs and requirements for any university system. The funding that universities receive a relevant influence on the scientific productivity of these. Thus the main objective of this study is to classify the Spanish regions in terms of scientific productivity and economic efficiency of their universities. It followed the same procedure used to prepare the 2009 ranking of research productivity in Spanish universities. The results show that there are differences in the classifications made on the basis of productivity and efficiency in the investigation. The more efficient Spanish regions in managing its resources to obtain research results are Catalonia, Asturias, Aragon, and Cantabria. From the results, each region can compare their situation with the rest and analyze strengths and weaknesses in research in terms of resources.     

Assessment of tobacco craving by means of the affective image visualization paradigm

Smoking cues that increase craving are subjectively described by smokers as pleasant rather than unpleasant. However, it remains controversial whether the motivational nature of these smoking cues is consistent with an appetitive or aversion-relief model of tobacco craving. In the two studies presented here, the Bioinformational model of emotion proposed by Lang was used to address this issue. In study I, 40 smokers (10 males) assessed a set of tobacco-related pictures and a subset of standard pleasant, neutral, and unpleasant pictures in order to examine how craving relates to the three general dimensions of emotion: valence, arousal, and dominance. Results showed that the tobacco-related images were all assessed as appetitive, and craving was correlated positively with valence (r = .863, p < .0001) and arousal (r = .923, p < .0001) and negatively with dominance (r = −.504, p < .002). In study II, 24 female abstinent smokers were examined using Lang’s startle modulation paradigm in order to assess whether tobacco-related pictures, compared to standard pleasant and unpleasant ones, inhibited the startle response, consistent with an appetitive model of tobacco craving. Contrary to expectations, the startle response during visualization of tobacco-related pictures was more similar in magnitude to the response to unpleasant than to pleasant images, a finding inconsistent with an appetitive model of tobacco craving.     

Cross-national comparisons of complex problem-solving strategies in two microworlds

Research in the fields of complex problem solving (CPS) and dynamic decision making using microworlds has been mainly conducted in Western industrialized countries. This study analyzes the CPS process by investigating thinking-aloud protocols in five countries. Participants were 511 students from Brazil, Germany, India, the Philippines, and the United States who worked on two microworlds. On the basis of cultural-psychological theories, specific cross-national differences in CPS strategies were hypothesized. Following theories of situatedness of cognition, hypotheses about the specific frequency of problem-solving strategies in the two microworlds were developed. Results of the verbal protocols showed (a) modification of the theoretical CPS model, (b) task dependence of CPS strategies, and (c) cross-national differences in CPS strategies. Participants' CPS processes were particularly influenced by country-specific problem-solving strategies.     

集体主义原则的公正性探析

必须坚持集体主义原则的公正价值向度,这是集体主义自身的内生性需要,也是社会对它的外源性要求。集体主义原则的公正性是较为复杂的,既有其绝对性的一面,又有其相对性的一面,这加剧了集体主义公正性落实上的困难。必须全面把握集体主义的公正性,在集体和个人的相互作用中推动集体主义的实现。     

Grandparent-grandchild relationships from the children's perspective: shared activities and socialization styles

The objective of this study is to describe the relationships between grandchildren and their favourite grandparents, by studying the socialization styles used by latter and the shared activities undertaken. The participants were 360 children between 10 and 12 years old, who completed the grandparent-grandchild relationship questionnaire of Rico, Serra and Viguer (2001) and the socialization questionnaire of Rey and Ruiz (1990). The results demonstrate the importance of gender and family line in the selection of the favourite grandparent, differences being shown in the types of shared activities and in socialization styles. It is concluded that in the majority of cases the profile of the favourite grandparent is the maternal grandmother, retired or a house wife, aged between 60-70, who lives in the same city as his/her grandchild, and who has contact with them several times a week. Furthermore, favourite grandparents get more involved with granddaughters than with grandsons, both in support and care activities and in cultural-recreational activities, and they primarily employ a democratic style. However, there are differences depending on the gender of the grandchild, with democratic principles being used more with girls and authoritarian ones with boys.     

Cognitive diagnosis models for multiple strategies

Cognitive diagnosis models (CDMs) have been used as psychometric tools in educational assessments to estimate students’ proficiency profiles. However, most CDMs assume that all students adopt the same strategy when approaching problems in an assessment, which may not be the case in practice. This study develops a generalized multiple-strategy CDM for dichotomous response data. The proposed model provides a unified framework to accommodate various condensation rules (e.g., conjunctive, disjunctive, and additive) and different strategy selection approaches (i.e., probability-matching, over-matching, and maximizing). Model parameters are estimated using the marginal maximum likelihood estimation via expectation-maximization algorithm. Simulation studies showed that the parameters of the proposed model can be adequately recovered and that the proposed model was relatively robust to some types of model misspecifications. A set of real data was analysed as well to illustrate the use of the proposed model in practice.
