The dynamics of closeness and betweenness
No full textBuechel B, Buskens V. The dynamics of closeness and betweenness. Working Papers. Institute of Mathematical Economics. Vol 398. Bielefeld: Universität Bielefeld; 2008.Although both betweenness and closeness centrality are claimed to be important for the effectiveness of someone's network position, it has not been explicitly studied which networks emerge if actors follow incentives for these two positional advantages. We propose such a model and observe that network dynamics differ considerably in a scenario with either betweenness or closeness incentives compared to a scenario in which closeness and betweenness incentives are combined. Considering social consequences, we find low clustering when actors strive for either type of centrality. Surprisingly, actors striving for closeness are likely to reach networks with relatively low closeness and high betweenness, while this is the other way round for actors striving for betweenness. This shows that in both situations the network formation process implies a social dilemma in which the social optimum is not reached by individual optimizing

An Experiment on the Effects of Embeddedness in Trust Situations
No full textThis vignette experiment was designed to study the effects of temporal embeddedness and network embeddedness in trust situations. The experiment uses a setting in which a buyer wants to buy a used car from a car dealer. We distinguish between effects on trust of the past relation and the effects of the expected future relation between the buyer and the dealer. A buyer can learn about the trustworthiness of the dealer from past transactions of the dealer. Moreover, the buyer can control the dealer if the buyer and the dealer expect more transactions in the future, because the buyer may sanction the dealer if the dealer would act untrustworthy in the present transaction, for example, by refraining from future transactions. Temporal embeddedness facilitates learning and control through the bilateral relation of the buyer and the dealer, while network embeddedness facilitates learning and control through third parties. In the experiment, subjects are asked to compare different settings for buying a used car, while the relation between the buyer and dealer is varied in these settings.
Three sessions of data collection were held. In total 125 subjects participated in the different sessions of the experiment, providing answers to 1249 pairs of vignettes.

Spreading information and developing trust in social networks to accelerate diffusion of innovations
No full textBackground: New food technologies developed by producers who want to spread their innovation require potential new adopters to receive information about the innovation as well as to develop trust about the appropriateness and quality of the new technology. Social networks are key for spreading information and for developing trust. In this essay, I will summarize sociological knowledge about how the structure of social networks can accelerate or inhibit innovation diffusion among consumers. Scope and approach: Innovation adoption is mostly a multistage process in which potential adopters/consumers need to obtain information first. A second step towards adoption is developing appreciation for the advantages of the innovation. A third step is the development of trust that the new product or technology indeed brings the advantages that it promises. I will explain based on existing literature why and in what manner, different structural properties of social networks are crucial for the consumer side of the adoption process. Key findings and conclusions: While for information diffusion predominantly the number of channels through which information can flow is important, and prevention of redundant information transfers helps to speed up information, the appreciation for the advantages of the innovation will require some redundancy and recurrent confirmation of the success of the innovation. To develop trust, even more confirmation is likely to be important and close social circles in which people repeatedly meet and know each other's acquaintances are known to be especially beneficial to create trust
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
