A maximum likelihood hierarchical disaggregate model for predicting choices of individuals

The absence of operational disaggregate lexicographic decision models and Tversky's observation that choice behavior is often inconsistent, hierarchical, and context dependent motivate the development of a maximum likelihood hierarchical (MLH) choice model. This new disaggregate choice model requires few assumptions and accommodates the three aspects of choice behavior noted by A. Tversky (1972, Journal of Mathematical Psychology, 9, 341–367). The model has its foundation in a prototype model developed by the authors. Unlike the deterministic prototype, however, MLH is a probabilistic model which generates maximum likelihood estimators of the aggregate “cutoff values.” The model is formulated as a concave programming problem whose solutions are therefore globally optimal. Finally, the model is applied to data from three separate studies where it is demonstrated to have superior performance over the prototype model in its predictive performance.

《孔丛子》中的“孔子诗论”

《孔丛子》六卷当出自“汉魏孔氏家学” ,其前三卷记孔子、子思言行 ,可能是辑先秦孔氏遗文。《孔丛子·记义》篇载有一大段孔子对《诗》的评论 ,其与上博简《孔子诗论》有着内在的关系 ,可以将它们视为同一个体系而相互参释和补充。《孔丛子》“诗论”与上博简《诗论》都反映了先秦儒家早期说诗的风格和内容 ,而与汉代形成的《诗序》传统不同。《孔丛子》“诗论”对朱熹的《诗经集传》有一定影响 ,在从汉代诗学向宋代诗学的转变过程中起了一定的作用。     

由知识对伦理的辩护到伦理对知识的批判——论知识的伦理价值

古希腊哲学最早将美德与知识相联系,“真”的达到就是“善”的实现,人的合目的性是建立在其合规律性的基础上的,伦理学从此有了独立存在的根据。近代知识论提出“知识就是力量”,将获得知识与获得幸福视为同一,知识(理性)是建立伦理的绝对普遍的坚实基础,人的尊严和主体性成为伦理追求的最大价值。20世纪以来,由于科学知识的异化,“知识与人的幸福和命运问题”凸现在当代伦理学面前。为知识找寻一条“应然”的光明之路,不仅是伦理学的理论使命,也是人类自身的神圣使命。     

马克思思想与后现代性

马克思与后现代都致力于实现从实体主义和本质主义的思维方式向实践的和关系性的思维方式的转变,但马克思思想中蕴含的历史自我意识则与后现代主义的历史相对主义形成了一种批判性的对话。后现代性语境下的马克思思想提醒我们反思当代西方思想的人类性价值以及当代精神的过渡性状况。作为马克思核心论阈的社会与社会化的人给后现代哲学所关注的核心问题主体间性提供了一种有效的反省与治疗价值。     

召唤与职业:驳韦伯对基督教职业观的理解——从克尔恺郭尔的基督教思想出发

韦伯在《新教伦理与资本主义精神》中,将职业与天职联系起来,并从这一角度指出,新教伦理促进了资本主义精神的兴起。该文认为这种直接的联系的基础是自然神论。通过引入克尔恺郭尔对西方理性形而上学的批判,笔者将论证,一方面,由自然神论衍生的基督教职业观在克尔恺郭尔的视野下是错误的,因为职业只是一个人生存的偶然性境遇之一,因此不是上帝的“召唤”。根据克尔恺郭尔对基督教的阐释,上帝的召唤是超越性的,这决定了它不可能直接地被人的理性理解,它以一种独特的———我称之为“否定性的”、“间接的”———方式被领会,召唤超越于职业,前者超越了人的理性,而后者是理性分工体系的产物;另一方面,上帝的召唤又与职业有关系。偶然性境遇恰恰是上帝进行召唤以及人作出回应的“场合”(occassion),一个基督徒如果占据某一职业,那么他(她)就必须辛勤劳动,甘愿“受苦”(suffering),韦伯正确地看到了基督徒对职业的重视、在职业上吃苦耐劳的表现,但未能正确地解释其原因。总之,依据克尔恺郭尔的思想,存在着一种有别于韦伯的基督教职业观,从而将基督教与资本主义精神联系起来是值得疑问的。

Syntactic and semantic processes in aphasic deficits: The availability of prepositions

The availability of a specific category of closed class items (prepositions) was examined in Broca's and Wernicke's aphasia. The role of prepositions was varied (syntactic/semantic) in two tasks: one requiring production of prepositions and the other acceptability judgments. Overall, it was easier to perform the acceptability task than to produce the target item. In the judgment task, Wernicke's aphasics more accurately determined the acceptability of prepositions in their syntactic role than in their semantic role, but Broca's aphasics showed no such difference. In the production task, Wernicke's aphasics again were more likely to produce prepositions which were in a primarily syntactic role. Broca's aphasics, however, failed to produce such syntactically based prepositions. The results suggest that the availability of a given closed class vocabulary form is not merely a function of its class membership but also of its functional role, and this fact serves to distinguish aspects of Broca's and Wernicke's aphasics' deficit.     

Deviation from hierarchical structure in recall: Is there an “optimal” structure?

Past research has suggested that proportionally more superordinate than sub-ordinate propositions are recalled from expository texts, following a hierarchical analysis of the text structure. Since free recall has typically followed this hierarchical pattern, several researchers have assumed that the related memory structures are isomorphic to the text structure. However, few of these studies have examined how individual differences and text structure interact to affect free recall. In two experiments, the assumption of hierarchical patterns of children's recall of expository text was tested. In Experiment 1, high- and average-ability fourth graders (9 years old) were asked to read and recall a passage. Experiment 2 was a replication and extension of Experiment 1. In this experiment, fourth and sixth graders (9 and 11 years old) read and recalled a different passage. The combined results of both experiments support the notion that there is probably no one optimal hierarchical structure for storage and retrieval of expository text.
