Acquiring Non-Object Terms: The Case for Time Words

We address the issue of children's understanding of abstract words with two studies on preschoolers' knowledge of the time-duration words minutes, hours, days, and years. The first study examines 4- and 5-year-olds' ability to answer questions about durations of common phenomena with duration terms. The second study examines 4- to 6-year-olds' comprehension of duration terms with a forced-choice pointing task. Both show that preschoolers' knowledge of such words is incomplete, but that it adheres to the pattern proposed in previous work with toddlers for abstract words. More specifically, children form lexical domains for such words even before they know their individual meanings, thereby allowing the children to often respond appropriately but not usually correctly to questions about abstract dimensions like time.     

L’accès aux médicaments : quelles contributions des règles sur les brevets de l’Accord de partenariat transpacifique global et progressiste ?

Enhanced protection for patents in free trade agreements would undermine access to medicines and show difficulties for developing countries with respect to public health issue. In the context of the Comprehensive and Progressive Trans-Pacific Partnership Agreement, however, after the withdrawal of the United States, the legal regime applicable to patents seems less rigid and, therefore, more favorable to access to medicines. This results, on the one hand, from certain flexibilities contained in this agreement itself; and on the other hand, the suspension of some material and procedural obligations. This article aims to analyze these two sides to justify the contribution of this agreement to ensure access to medicines.     

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... s_k. 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 2^O(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.     

Consumer ethnocentrism,cultural sensitivity,and intention to purchase local products—evidence from Vietnam

• 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.

汉语作为第二语言的越南大学生汉字部件意识的发展*

以226名将汉语作为第二语言的越南大学一到四年级学生为研究对象,以低频独体字、部件熟悉假字和部件不熟悉假字为材料,采用延迟书写任务,考察了不同年级的越南大学生汉字部件意识的发展及其影响因素。结果发现：（1）学习3个月汉语的大一学生能以部件作为汉字加工单元,其延迟书写部件熟悉假字显著好于低频独体字,并与高年级学生没有差异,说明越南大学生很早就发展出了汉字部件意识;（2）不同年级大学生书写部件不熟悉假字的成绩都显著低于部件熟悉假字,也低于低频独体字,表明部件构字能力是越南大学生汉字书写的重要影响因素。（3）越南大一学生的汉字书写成绩受到汉字结构的影响,左右结构优于上下结构,但其他年级的成绩不受汉字结构的影响。     

Immediate effects of snoezelen? treatment on adult psychiatric patients and community controls

The effectiveness of Snoezelen? multi-sensory stimulation treatment was evaluated with 50 psychiatric patients (25 men, 25 women) and 50 hospital employees (25 men, 25 women). Pre and post-treatment physiological responses (galvanic skin conductance response, heart rate, and percentage blood oxygen) were compared and participants were evaluated post-treatment for perceived psychological benefits with a nine-item questionnaire. Results indicate that participation in a single 20-minute Snoezelen? session had significant and positive physiological effects on both the patient and staff groups. Also, post-treatment participants in both groups did not perceive any change on the dimension reserved-outgoing but felt more sleepy, passive, relaxed, cheerful, focused, optimistic, calm, and comfortable. Consequently, beneficial physiological and psychological Snoezelen? treatment effects were apparent for both patients and controls.     

Experiences and Beliefs as Predictors of Ethnic Identity and Intergroup Relations

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.     

Associative memory in three aplysiids: correlation with heterosynaptic modulation

Much recent research on mechanisms of learning and memory focuses on the role of heterosynaptic neuromodulatory signaling. Such neuromodulation appears to stabilize Hebbian synaptic changes underlying associative learning, thereby extending memory. Previous comparisons of three related sea-hares (Mollusca, Opisthobranchia) uncovered interspecific variation in neuromodulatory signaling: strong in Aplysia californica, immeasureable in Dolabrifera dolabrifera, and intermediate in Phyllaplysia taylori. The present study addressed whether this interspecific variation in neuromodulation is correlated with memory of associative (classical conditioning) learning. We differentially conditioned the tail-mantle withdrawal reflex of each of the three species: Mild touch to one side of the tail was paired with a noxious electrical stimulus to the neck. Mild touch to the other side served as an internal control. Post-training reflex amplitudes were tested 15-30 min after training and compared with pre-test amplitudes. All three species showed conditioning: training increased the paired reflex more than the unpaired reflex. However, the temporal pattern of conditioning varied between species. Aplysia showed modest conditioning that grew across the post-test period. Dolabrifera showed distinctly short-lived conditioning, present only on the first post-test. The time course of memory in Phyllaplysia was intermediate, although not statistically distinguishable from the other two species. Taken together, these experiments suggest that evolutionary changes in nonassociative heterosynaptic modulation may contribute to evolutionary changes in the stability of the memory of classical conditioning.     

Relationship between age and aspects of depression: consistency and reliability across two longitudinal studies

In this study, the authors examined cross-sectional and longitudinal age and gender differences in each of the Center for Epidemiological Studies Depression Scale's 4 subscales of depressive symptomatology. Two independent studies (Sample 1 = 2,076; Sample 2 = 943) were used for purposes of establishing stability of findings. Results indicate a reasonable degree of stability among adults under 70 years of age. However, there were significant age-related increases in somatic symptoms and lack of well-being after approximately 70 years of age, whereas symptoms related to depressed affect and interpersonal problems remained stable. Notably, depressive affect symptoms remained stable given significant age-related somatic changes. The addition of comorbid physical illness to the analysis did not reduce the association between age and depressive symptoms, indicating that part of the association was not substantially accounted for by physical health.
