The demand for social interaction

In this paper social interaction is modeled as a consumer good. A model of household production is employed to derive the demand for social interaction. The model shows that the demand for social interaction is a function of its price, the price of other goods and income. The theory is tested with data from the General Social Survey and the results show that social interaction can be explained as the consequence of utility maximizing behavior by individuals. These results are in contrast to social capital theorists who have attributed these changes to factors such as increased community heterogeneity.     

A Spatio-Temporal Model for Functional Magnetic Resonance Imaging Data – with a View to Resting State Networks

Abstract.  Functional magnetic resonance imaging (fMRI) is a technique for studying the active human brain. During the fMRI experiment, a sequence of MR images is obtained, where the brain is represented as a set of voxels. The data obtained are a realization of a complex spatio-temporal process with many sources of variation, both biological and technical. We present a spatio-temporal point process model approach for fMRI data where the temporal and spatial activation are modelled simultaneously. It is possible to analyse other characteristics of the data than just the locations of active brain regions, such as the interaction between the active regions. We discuss both classical statistical inference and Bayesian inference in the model. We analyse simulated data without repeated stimuli both for location of the activated regions and for interactions between the activated regions. An example of analysis of fMRI data, using this approach, is presented.     

Hook‐Ups and Train Wrecks: Contextual Parameters and the Coordination of Jazz Interactions

This article discusses the importance of several parameters of context integral to jazz musicians' ability to hear musical signs as meaningful, such as performers' individual backgrounds and the various other styles of music available in the aural landscape, and how those parameters influence what the musicians play. Several examples from an ongoing ethnography of jazz jam sessions suggest that context is constituted by several variables, that different variables may become salient at different times, and that different interactants vary in their ability to attend to these variables. This study thus extends and elaborates frame analysis by showing that, while an interaction frame of the sort described by Goffman (1974) may perdure, it is subject to change, and the nature of the context it provides for interactions can change whenever a new interaction is initiated.     

略论修辞学的科学化——兼评王希杰修辞思想

修辞学是研究提高语言表达效果的规律的科学。修辞学的规律可以概括为四条:选择律、互动律、适应律、效果律。四条规律贯穿于一切修辞中,以构建科学的修辞殿堂。王希杰的“三.一”创新理论有力地促进了中国修辞学的科学化和现代化。     

论大学文化的思想政治教育价值

大学文化对高校的思想政治教育工作具有独特的不可忽略的价值。大学文化在思想政治教育中具有思想导入、教化育人、健全心灵和精神塑造等功能,在大学文化建设中要切实落实思想政治教育。     

影响教师职业倦怠的情境因素、人格因素及其之间的关系

影响教师职业倦怠的因素主要可以归纳为情境因素和人格因素。以往的研究都侧重于对情境因素与人格因素的分别考察，而对二者之间的关系研究较少，而这正是今后教师职业倦怠研究的一个重要方向。     

公平与效率关系问题辨析——评坚持"效率优先、兼顾公平"的若干观点

党的十六届四中全会以来,中央再三强调要注重社会公平,加大调节收入分配的力度,未再提“效率优先、兼顾公平”。一些学者主张仍要坚持“效率优先、兼顾公平”,其种种论据是不能成立的。公平与效率,从根本上说是内在有机统一和互动的关系,不存在孰先孰后、孰重孰轻的问题,二者是互为条件、互相制约、互相促进的。     

价值共创还是价值共毁?——顾企价值创造互动行为协调机制研究

本文基于演化博弈的视角,通过构建顾企价值创造互动行为演化博弈模型,深入剖析其演化过程及其影响因素,并运用MATLAB模拟验证相关参数变化对演化结果的影响,从而揭示了顾企价值创造互动行为协调机制的内在机理.研究结果表明:顾企价值创造互动行为呈现出"共创型互动"与"共毁型互动"并存的演化特征;资源整合能力、价值共创效率、资源投入意愿以及惩罚的提高能够促进顾企价值创造互动行为的协调稳定,双方互动行为收敛于"共创型互动"而最终实现价值共创;但成本系数与投机收益的提高则会使其趋于不协调状态,双方互动行为收敛于"共毁型互动"而最终造成价值共毁.     

纳米氧化铁材料的磁弛豫研究

由Fe-O的超细粉末压制成纳米固体，该过程使相邻微粒间形成界面。由于总体的磁弛豫依赖于有效各向导性能，界面的存在出现的界面各向异性能将会改变纳米的磁弛豫行为．对α-Fe2O3和γ-Fe2O3的Mossbauer谱研究测量表明在抑制起顺磁弛豫时，界面的交换相互作用是主要的。     

崛起的中国与国际组织：一种互动关系的分析

国际组织在国际事务中日益活跃是当今世界全球化浪潮的一个重要表现和特征。每个国家的兴衰成败已与国际组织密切相关。中国的崛起、中国国际地位的重要性和特殊性,对中国参与国际组织以及国际组织对中国的认同和接纳,产生了不容忽视的重要影响。当前,中国与国际组织已形成相互影响、彼此促进、良性互动的态势,这对中国的国家发展和国际社会的和平与发展都具有重大意义。
