Prestige in social dilemmas: A network analytic approach to cooperation among Bogotá’s art organizations

What brings about cooperation in social dilemmas? The literature has proposed motivational and strategic solutions to social dilemmas. In motivational solutions, actors cooperate because they care about fairness. In strategic solutions actors cooperate because their chances to exploit others are reduced. This paper argues that actors also cooperate in order to gain prestige. The effect of prestige on cooperation is examined relying on a unique set of network and covariate data on art organizations (museums, independent art spaces, galleries and art foundations) in Bogotá, the capital of Colombia. Bogotá is a not a very likely environment for cooperation, since distrust is still widespread after a long civil war. The temporal exponential random graph models predict dyadic cooperation (i.e., between two actors) based on past and present cooperation in the network as well as of the organizations’ characteristics. The analysis thus controls for the effect of actors’ past and present interaction on the present cooperation dilemma. The paper shows that prestige affects cooperation in social dilemmas independent of past and present interactions.     

On the Jade Culture to Construction and Significance of Euphemism Style of Ci-poetry of the Song Dynasty

Euphemism is a remarkable feature of Ci-poetry of the Song dynasty. There are many reasons for the formation of euphemism style in Ci-poetry. As a deep psychological structure of a nation, Jade culture is of great significance to the construction of the graceful style of Song Ci. Jade is the symbol of feminine beauty and has similar aesthetic meaning with women. As an accompanying text,jade culture acts on the creation of feminine soft image from different angles in Song Ci. Jade culture interacts with the stylistic structure of Ci to guide readers to form graceful aesthetic complex. Jade culture constitutes the graceful style of Song Ci from the aspects of image, language style and emotional expression.

Exponential random graph models for management research: A case study of executive recruitment

We introduce a recent development in the statistical analysis of relational data that offers rigorous discrimination of a variety of structural and behavioural effects of interest to management research. Exponential random graph models account for the highly interdependent nature of network data that are problematic for the predominant inferential statistical analysis used in management research. We illustrate the value of the approach with an application focused on executive recruitment by large UK firms, modelling migrations of managers among firms as a network of relationships. We find rigorous statistical support for the influences of industry origin in executive recruitment, particularly in relation to legal and accounting activities. The flexibility and sophisticated relational variables available in the models offer considerable analytical power of value to a wide range of management applications.     

Social networks and spatial configuration—How office layouts drive social interaction

This paper analyzes the spatial dimensions of office layouts in diverse knowledge-intensive workplace environments based on the theoretical and methodological propositions of Space Syntax, and brings this together with the analysis of intra-organizational interaction networks. Physical distances between agents are modeled in different ways and used as explanatory variables in exponential random graph modeling. The paper shows that spatial configuration in offices can be considered an important but not sole rationale for tie formation. Furthermore, it is shown that spatial distance measures based on detailed configurational analysis outperform simple Euclidean distance metrics in predicting social ties.     

A new scalable leader-community detection approach for community detection in social networks

Studying social influence in networks is crucial to understand how behavior spreads. An interesting number of theories were elaborated to analyze how innovations and trends get adopted. The traditional view assumes that a minority of members in a society possess qualities that make them exceptionally persuasive in spreading ideas to others. These exceptional individuals drive trends on behalf of the majority of ordinary people. They are loosely described as being informed, respected, and well connected. The leaders or influential are responsible for the dissemination of information and the propagation of influence. In this paper, we propose a new scalable and a deterministic approach for the detection of communities using leaders nodes named Leader-Community Detection Approach LCDA. The proposed approach has two main steps. The first step is the leaders’ retrieval. The second step is the community detection using similarity between nodes. Our algorithms provide good results compared to ground truth membership community.     

Socio-material network analysis: A mixed method study of five European artistic collectives

In this paper, I argue that we can better understand the relationship between social structure and materiality by combining qualitative analysis of practices in shared physical space with statistical analysis. Drawing on the two-mode approach, I treat social and material structures together with the relationship between them as a two-level socio-material network. In a mixed method study, formalized ethnographic data on such networks in five European artistic collectives are subjected to multilevel exponential random graph modelling. It sheds light on how different kinds of interpersonal ties condition the engagement of individuals with similar materiality over time.

轮图与舵轮图的超边优美标号

1994年, Mitchem和Simoson在研究标号图的问题时,提出了超边优美图的概念。在随后的研究中,一些图被证明具有超边优美性质,同时关于超边优美图的一些猜想也被提出。本文利用递归方法构造了轮图Wn与舵轮图Hn的超边优美标号,证明了这两类图是超边优美图。     

《闺秀诗话》与《闺秀诗评》关系及作者考述

淮山棣华园主人《闺秀诗评》与苕溪生《闺秀诗话》二书因不知作者具体为何人,产生很多疑问。仔细比对《闺秀诗评》与《闺秀诗话》所载条目,发现《闺秀诗话》所载的106则中,有71则与《闺秀诗评》完全相同或者相似,可见苕溪生编辑《闺秀诗话》时一定参阅过《闺秀诗评》,但不知因何只字未提;同时根据相关资料考证棣华园主人应就是清代戏曲家黄钧宰,发现苕溪生与民初小说家徐枕亚有相似之处。
