关键词： Doi-Hopf模   Turaev   G-余代数   Turaev辫子G-范畴  

摘要： 设G是一个群.利用Turaev辫子群范畴的性质,在Doi-Hopf数据(H,A,C)上构造一个Turaev辫子G-范畴,其中H,A,C是Hopf代数.进一步,当C为有限维时,在一簇Smash积代数{A#~HC~*(α)}_(α∈G)上构造一个拟三角Turaev G-余代数A#~HC~*,其表示范畴与_AM^C(H)是同构的.

关键词： 故事   集体行动   社会规范   情景定义   集体记忆  

摘要： "故事"是人们在日常生活中很早就使用并熟悉的词汇和现象。本文试图尝试把"故事"作为一个分析性的理论概念引入到社会研究当中来,将其与影响着短时段社会运行的集体行动领域和影响着长期行为特征的制度规范研究领域中,与"故事"具有一定亲和力的已有理论研究结合起来,给"故事"概念以初步的定位探讨。通过文献梳理和分析我们看到,将"故事"引入集体行动理论进行讨论时,"故事"通过短时的情景定义发挥作用,对既定环境及将面临的境况的主观解释和判断产生影响,进而影响人自身的行动决策及集体行动的状态;而在有关社会规范与"故事"相联系的讨论中,"故事"是通过集体记忆作用于共同规范的形成和演化,从而在一定程度上成为社会公众规范的载体。

关键词： Mathematical models of pricing   Pricing   Supermarkets   Market power   Competition (Economics)   One-stop shopping  

摘要： In many competitive settings, consumers buy multiple product categories, and some prefer to use a single firm, generating complementary cross-category price effects. To study pricing in supermarkets, an organizational form where these effects are internalized, we develop a multi-category, multi-seller demand model and estimate it using UK consumer data. This class of model is used widely in theoretical analysis of retail pricing. We quantify cross-category pricing effects and find that internalizing them substantially reduces market power. We find that consumers inclined to one-stop (rather than multi-stop) shopping have a greater pro-competitive impact because they generate relatively large cross-category effects.

关键词： φ-features   prosodic adjunct   Spanish   stress   syntax-phonology interface  

摘要： In this paper, I provide an analysis of Spanish stress with the following three characteristics: (a) both verbal and non-verbal stress are accounted for in a single, unified, system, (b) the three-syllable window for stress is accounted for in a principled way, and (c) the stress algorithm has no access to the morphosyntactic structure. I do this by extending Roca's analysis of variable edge parameters for stress in Spanish non-verbs to verbs, and by arguing that morphemes which mark for only person, number, and gender (φ-features) are outside of the domain of stress because they are prosodic adjuncts.

关键词： CATEGORIES (Mathematics)   ANALOGY   COGNITION   RATIONAL numbers   GROUP theory   MATHEMATICS  

摘要： Category Theory, a branch of mathematics, has shown promise as a modeling framework for higher-level cognition. We introduce an algebraic model for analogy that uses the language of category theory to explore analogy-related cognitive phenomena. To illustrate the potential of this approach, we use this model to explore three objects of study in cognitive literature. First, (a) we use commutative diagrams to analyze an effect of playing particular educational board games on the learning of numbers. Second, (b) we employ a notion called coequalizer as a formal model of re-representation that explains a property of computational models of analogy called "flexibility" whereby non-similar representational elements are considered matches and placed in structural correspondence. Finally, (c) we build a formal learning model which shows that re-representation, language processing and analogy making can explain the acquisition of knowledge of rational numbers. These objects of study provide a picture of acquisition of numerical knowledge that is compatible with empirical evidence and offers insights on possible connections between notions such as relational knowledge, analogy, learning, conceptual knowledge, re-representation and procedural knowledge. This suggests that the approach presented here facilitates mathematical modeling of cognition and provides novel ways to think about analogy-related cognitive phenomena.

关键词： Technology   Technological innovations   Service industries   Labor   Vehicles  

摘要： The author discusses how the progression of vehicle technology will change labor measurement in a typical service shop business. Topics discussed include the need for shops to determine how much labor they need in each category for success, the setting of labor rates for each category and the need for better job quoting skills.

关键词： Semantic relatedness   False memory   Anterior temporal lobe   Transcranial direct current stimulation (tDCS)  

摘要： A dominant view of the role of the anterior temporal lobe (ATL) in semantic memory is that it serves as an integration hub, specialized in the processing of semantic relatedness by way of mechanisms that bind together information from different brain areas to form coherent amodal representations of concepts. Two recent experiments, using brain stimulation techniques along with the Deese-Roediger-McDermott (DRM) paradigm, have found a consistent false memory reduction effect following stimulation of the ATL, pointing to the importance of the ATL in semantic/conceptual processing. To more precisely identify the specific process being involved, we conducted a DRM experiment in which transcranial direct current stimulation (anode/cathode/sham) was applied over the participants' left ATL during the study of lists of words that were associatively related to their non-presented critical words (e.g., rotten, worm, red, tree, liqueur, unripe, cake, food, eden, peel, for the critical item apple) or categorically related (e.g., pear, banana, peach, orange, cantaloupe, watermelon, strawberry, cherry, kiwi, plum, for the same critical item apple). The results showed that correct recognition was not affected by stimulation. However, an interaction between stimulation condition and type of relation for false memories was found, explained by a significant false recognition reduction effect in the anodal condition for associative lists that was not observed for categorical lists. Results are congruent with previous findings and, more importantly, they help to clarify the nature and locus of false memory reduction effects, suggesting a differential role of the left ATL, and providing critical evidence for understanding the creation of semantic relatedness-based memory illusions.
