Neurofunctional (re)organization underlying narrative discourse processing in aging: evidence from fNIRS

Relatively few studies have analyzed the mechanisms underlying the cognitive changes that affect language in the elderly, and fewer have done so for narrative discourse. The goal of this study was to explore the neurofunctional changes associated with aging for different components of narrative discourse. Functional near-infrared spectroscopy (fNIRS) and behavioral data on 10 younger adults and 10 healthy elderly participants were collected. Ten younger adults in a non-proficient second language condition were included to explore the possibility that the age-related neurofunctional reorganization partly expresses demanding resource allocation. Results show within- and across-hemispheric differences in the neurofunctional pattern of activation in the older participants with reference to the younger ones, partially shared with the low-proficiency young adults, providing support for the recognized mechanisms underlying neural reserve and compensation. fNIRS was shown to be appropriate for studying the age-related neurofunctional reorganization of complex cognitive abilities.     

中学生消费价值观在家庭理财教育方式与消费决策风格之间的中介作用

目的：考察中学生消费价值观在家庭理财教育方式与消费决策风格之间的中介作用。方法：377名中学生完成了中学生消费价值观问卷、家庭理财教育方式问卷和中学生消费决策风格问卷。结果：父母积极的教育方式可通过树立合理的消费价值观来促进中学生形成理性的决策风格;父母消极的教育方式一方面通过树立不合理的消费价值观助长中学生非理性的决策风格,另一方面通过减弱合理的消费价值观来减弱其合理的决策风格。结论：中学生消费价值观在家庭理财教育方式与消费决策风格之间起中介作用。     

Bonds and boundaries: Network structure,organizational boundaries,and job performance

We propose and test a framework that describes the relationship between network structures and job performance. We provide an integration of the current conceptualizations of social capital as they pertain to job performance outcomes by taking a multi-dimensional view of job performance. We break down job performance into creativity, decision-making, task execution, and teamwork, and distinguish the effect of structural holes within and across the organizational boundary on these four job performance domains. In an analysis of 318 managers, we find that networks rich in structural holes that cross the organizational boundary had a positive association with creativity and decision-making, whereas networks with few structural holes within the organization had a positive association with task execution and teamwork. We discuss the theoretical implications for integrating the social capital, boundary spanning, and network structure literatures, as well as the practical benefits of giving much more precise advice to managers and employees regarding how to use networks to improve performance at work.     

从“金规则”看儒家伦理“仁”的思想体系的本质特征及其与基督教伦理的异同

《走向全球伦理宣言》的"金规则"("己所不欲,勿施与人")与儒家伦理相符,即"恕道",亦即"仁"的思想体系的本质特征。"己欲立而立人,己欲达而达人"是对"仁"的积极表述;"己所不欲,勿施与人"是对"仁"的消极表述。儒家的"仁爱"观与基督教的"圣爱"观都是普世之爱,由于二者的起源、发展方式不同,所以表现形式也不同。儒家的"仁爱"观与"敬"分不开,其极至状态为"四海之内,合敬同爱"。     

Walking and periventricular leukomalacia: locomotor characteristics and brain imaging (MRI)

The aim of the present study was to compare the walking abilities in infants with and without periventricular leukomalacia and to see whether the severity of the brain damage was related to locomotor outcome of the infants at 12 and 18 months. 47 newborns were included in the study based on white matter abnormalities on ultrasound. Magnetic resonance imaging (MRI) recordings during the neonatal period were used to identify and quantify the location and severity of the brain lesions. Locomotor outcome was assessed in terms of disability at 12 and 18 months. The quality of walking, including global and segmental gait parameters, was measured for the infants who could walk independently at 18 months and compared to a group of healthy control infants. The number of children who could walk was related to the extent of white matter abnormalities seen on the neonatal MRI, but the quality of walking was not.     

学龄早期Asperger综合症儿童行为问题和注意、行为抑制功能研究

研究采用Achenbach儿童行为量表(父母用表)和注意、行为抑制及动作协调性行为任务对12名学龄早期的Asperger综合征儿童与29名在年龄及智力水平上与之匹配的正常儿童在行为问题、注意、行为抑制及动作协调等方面进行了比较.结果发现,在控制了年龄和智力因素后:1)Asperger综合征儿童的社会能力与正常儿童相比明显较差,同时常伴随有交往不良、社交退缩、焦虑、忧郁、强迫性、攻击性和多动等一系列行为问题;2)Asperger综合征儿童表现出一定的注意和行为抑制障碍,动作的协调性和灵活性较差.     

组合原则

组合原则是逻辑语义学的基本原则,表现为函项的思想和句法与语义的对应。就构造逻辑系统而言,组合原则是一种方法论。作为延伸到自然语言形式语义学的产物,组合原则起到一种核心灵魂的作用。组合原则在理论层面和应用领域皆获得一些有价值的结果。自然语言违反组合原则的实例主要表现为歧义现象、语用因素和句法与语义不对应的情况,这正是调整组合原则的适用条件从而促进形式语义学发展的契机。     

汉语致使句的形式处理

There are at least five kinds of causative constructions in Chinese, the constructions of the collocation of verbs and prepositional phrases, verb-copying constructions, “ba” constructions with an object ahead, verb-copying constructions with their complements, and pivotal constructions with commands. But the current type-logical grammar has no tools representing the meanings of causative constructions. It would be neither intuitive nor simple to describe these constructions by means of the current type-logical grammar. So we intend to improve the type-logical grammar by adding CAUSE as a logical constant, complementing the structure rules about the movement and addition or deletion of some components of causative constructions, assigning categories to Chinese nouns and prepositions; then we give an intuitive as well as simple analysis on these causative constructions. Based on this work we shall extend the multimodal system of type-logical grammar, increase structure postulates, make constraints on frame semantics, and then prove the soundness and completeness of that system.
