INFLUENCE OVER OBSERVERS OF STRUCTURAL POWER: An Experimental Investigation

Research in network exchange theory and status characteristics theory that distinguishes power from influence has proven productive, but leaves open the question of whether a causal relationship exists between these two central, sociological concepts. Past research has found that structural power in exchange increases expectations for competent performance of the power user on a subsequent cooperative task. However, once the power advantage has been removed, previous research has failed to find increased influence of power users, perhaps because those subjected to power use react negatively to perceptions of the high-power actor as selfish or greedy. In society, the results of power used on relatively few people can be observed by many who may not react negatively to the power use because they are not directly exploited. Thus we predicted that observers of power processes would form high expectations for the competence of, and be influenced by, power users. An experimental study supported the predictions: A partner who had been in a high-power position had more influence over observers than did a partner who had been in a low-power position. An interaction was found such that the high-power partner had more influence over observers of power in strong-power networks, but not in weak-power networks.     

Resource characteristics in social exchange networks: Implications for positional advantage

Despite the wide range of resources that traverse social networks, social exchange research has focused on only a narrow subset. Notably, prior social exchange research has not considered resources like information that have the capacity to diffuse through networks. The current study investigates how differences between the standard social exchange resource and an information-type resource affect the advantage provided by one's network position. Results of a laboratory experiment support predictions and offer two new insights to the foundations of positional advantage: (1) the location of advantageous positions in a network differs by resource characteristics, and (2) only in particular situations is a single position able to experience high levels of both power and exchange frequency.     

Centrality and power revisited: actor success in group decision making

For many years, network analysts viewed positional centrality as a source of social power. More recently, laboratory studies of exchange networks have called the centrality–power link into question: under zero-sum exchange conditions, the ability of certain actors to directly exploit others has been found to account for power independent of actors' centrality. But most observers believe that in non-zero-sum communication networks, centrality should positively affect power. In this study we examine the effect of centrality on power in a communication network involving group voting on political issues. Using a model in which actors' votes are determined by the strength of their initial positions and the social pressures to which they are subjected, we conduct computer simulations to examine the extent to which actors in various network positions achieve favorable political outcomes. Our findings indicate that the link between centrality and power is highly contingent on the structure of the network. In networks with a central actor and an odd number of subgroups, central actors fail to dominate. In fact, in these networks, when peripheral actors are able to directly influence one another, the central actor becomes the least powerful in the network. In networks with a central actor and an even number of subgroups, however, the central actor dominates even in situations with connected peripherals. The highly contingent effect of centrality on power accords with the findings of exchange theorists who have studied power under zero-sum conditions. This raises questions about the nature of the distinction between communication and exchange networks.     

Votes,Favors, Toys,and Ideas: The Effect of Resource Characteristics on Power in Exchange Networks

Abstract

The goal of this research is to understand how resource characteristics influence the development of power in exchange networks. Transferability and duplicability are identified as fundamental resource characteristics that have not been examined systematically in prior social exchange research. Varying resource transferability and duplicability alters the mechanisms that produce power and determine which positions in a network have a power advantage. To predict where power will develop, I rely on existing measures for previously studied resources and introduce relevant principles of network structure for resources that have not been studied before. This theoretical logic is supported by a series of simulated exchange networks that apply behavioral principles observed in prior experimental research to the exchange of a broader variety of resources than previously considered. Results indicate how the pattern of power use in a network is contingent upon the type of resource being exchanged.     

Ideologically Structured Information Exchange among Environmental Groups*

Abstract We use social network analysis to test the hypothesis that group ideology affects information exchange among environmental groups. The analysis is based on interviews with leaders of 136 environmental groups in Alabama. This paper adds to the literature on resource mobilization among social movement organizations by exploring information exchange among a wide range of environmental groups across an entire state, and by incorporating ideology into our analysis. A typology of environmental groups was developed based on willingness to engage or not engage in political and legal activism to pursue their goals. We found a level of information exchange between activist groups twice that among all other groups. We also found that differing ideological profiles did not limit the flow of information between groups, taken as a whole. We conclude that the relatively high level of connectivity is attributable in part to the presence of paid staff among several key activist groups, making these groups important resources for technical and non‐technical support for all groups across the state.     

Power,governance and distributional skew in global value chains: Exchange theoretic and exogenous factors

The relationship between power, governance and value creation/capture is a central concern in global value chain (GVC) research. In the context of calls to develop a more expansive view of power in GVCs, we argue for retaining a focus on bargaining power, but shifting the conceptualization of bargaining power from the dyad to the network. We advance two arguments. First, we elaborate an exchange theoretic model in which skew of value capture is a function of the degree of power asymmetry inherent in the ratio of buyers to suppliers. Second, we explain how this model can be expanded to consider the role of external factors, such as the institutional and normative contexts in which exchange occurs. Rather than see these factors as contending forms of power, we treat them as forces that can affect value skew by either attenuating the bargaining power of lead firms or by moderating the distributional effects of power asymmetries between exchange partners. We conclude that an exchange theoretic approach to bargaining power in GVCs provides a parsimonious framework for explaining how inter-firm governance shapes the distribution of value capture in global production.     

The embeddedness of social relations in inter-firm competitive structures

Collaboration with direct competitors is a valuable, yet risky, strategy that might pave the way for competitive advantages. Thus far, we have lacked a detailed understanding of how competitive relations between firms shape collaborative relations between their managers, and consequently the structural interdependencies at both levels. The primary objective of this study is to understand the multi-level structure underlying the ambiguous relationship of coopetition, a state of simultaneous collaboration and competition. Hence, we investigate the influence of perceived inter-firm competition on interpersonal knowledge flows among managers within three high-tech clusters by applying multi-level exponential random graph models to network data. Our results reveal that the interpersonal exchange of advice and information depends strongly on the inter-firm competitive structure and that competitive structures shape these interpersonal exchanges in different ways. Thereby, our research demonstrates that managers utilize asymmetries by means of perceived competitive relations to seek work-related advice and information from their competitors and that stronger forms of competition are significant, but not insuperable, obstacles to the exchange of knowledge.     

PARTICIPATORY SPATIAL KNOWLEDGE MANAGEMENT TOOLS

Different types of spatial knowledge (expert, sectoral, tacit and community) are strategic resources in urban planning and management. Participatory spatial knowledge management is a major method for eliciting various types of knowledge, providing a platform for knowledge integration and informing local action and public policy. Knowledge types linked to a specific geographical locality can be integrated through geographical information systems. Recent developments in geographical information and communication technology (geoICT) have extended the opportunities for participatory spatial knowledge production, use and exchange. However, data reliability of user-generated content, social exclusion due to dependence on technology and the interpretation and implications of digital maps are major concerns. The challenge is how to integrate and utilize multiple knowledge sources for improving urban management and governance. This paper integrates the literature on knowledge types and knowledge production processes with available geoICT tools for the production, use and exchange of knowledge sources and applies it to examples from Asia, Africa and Latin America. From this review, we provide a heuristic framework for assessing the extent to which participatory spatial knowledge management tools can be instrumental on several fronts. We argue that technological developments of knowledge production have not fully addressed important issues related to accountability, empowerment, control and use of knowledge. Moreover, these developments may foster social exclusion, which could detract from the benefits of participatory spatial knowledge management in the context of urban sustainability.     

The Industry of Illegal Migration: Social Network Analysis of the Brazil‐US Migration System

In this article, we analyse the process of migration by applying a social network methodology. Using the personal network approach, we focus on a case study of the Brazil‐US migration system to analyse the formation of the so‐called “industry of illegal migration”. We suggest that in migration systems, brokerage evolves not only because of historical and cultural changes, but also because the changes emerge within a structured environment in which brokerage can thrive, and this, in turn, causes the social networks to support and produce specialized actors (individuals and organizations) embedded in the “right positions” of the social structure in the migration process. In this particular case study, we suggest that brokerage seems to take place through gender‐oriented networks and the personal experience and structural power of returned migrants. These returned migrants usually have more varied social contacts and types of relationships from which they can obtain richer information about the migration system.     

Who Can Tell? Network Diversity,Within‐Industry Networks,and Opportunities to Share Job Information

This article examines opportunities to share job information. It adds to the growing body of research on information holders and complements existing research that explains what kinds of networks and network positions provide the greatest benefit to job seekers. Data from an exploratory study of entry‐level, white‐collar workers are used to relate opportunities to share information—defined to consist of both knowledge of a job opening and awareness of a potential applicant among one's network members—with information holders’ network composition. The data show that information holders with strong within‐industry networks have more opportunities to share information and do share more information. Information holders with diverse networks more often identify potential applicants for jobs and thus have more opportunities to share information. However, despite having more opportunities to do so, they do not share information more often than those with less diverse networks. These findings, combined with the growing literature on information holders, suggest that different aspects of network composition affect the flow of job information at different stages and thus by different mechanisms.     

Beyond mere information transfer: The importance of a relational approach to market-related internal communication

Despite the significance of relationship management in any information provision or exchange, public relations scholarship has typically focused on examining the underlying internal communication processes from a transactional perspective. These processes are frequently associated with organizational information dissemination, overlooking other critical contents to make strategic decisions. This study draws market information processing into the debate about internal communication, providing a greater understanding of how a relational approach can improve market intelligence dissemination. Results show that an effective management of market knowledge requires the use of such an approach, which in turn, cultivates the shared interpretation of market information and innovation performance. The findings stimulate fresh discussion about the nature and development of internal communication knowledge and practice.     

The impact of social networks on the occupational status of migrants

This paper postulates that there is a continuous exchange of information and knowledge between those who share the common bond of having migrated to the US. The individual components of this information exchange constitute social networks. The 2 hypotheses tested are 1) immediate social networks and people known in the US facilitate the flow of information both to new migrants and between established migrants, thus promoting upward social mobility; and 2) access to broader network ties, organization membership, extra-ethnic friendships, and familiarity with established institutions smooths the transition process, resulting in increased social position. The data used comes from a study conducted in 1982-1983 in 4 Mexican sending communities (2 rural, 2 urban), for a total of 440 migrants. Results show that migrants in every socioeconomic bracket reported access to some or all social network characteristics. There was contact with either a family member or acquaintances from the migrants' town of origin. Over 50% of migrants reported knowing many fellow townspeople. Twice as many migrants belong to a sports club as to a social or religious organization. Very few rural migrants report knowing no townspeople, while 32% of urban migrants claim no knowledge of fellow migrants from their town of origin. Urban origin migrants report more contacts with those of other ethnicity than rural migrants. Those employed in agriculture are least acquainted with social information and contacts, while those in skilled and service sectors are well acquainted with them. The results of fact and analysis show that 1) access to personal US networks results in an average 4.4 point advantage in occupational prestige scores over no access, and 2) utilizing institutional US networks combined with any cumulative US experience gives a migrant a 5 point advantage over a fellow migrant with identical experience level but no institutional network contacts. This is also true for institutional Mexican networks. Thus success or failure in migrating is partly due to migrants' societal infrastructure and the fact that available information and social networks are accessed and utilized differently by different migrants.     

Strains in Sustainability Debates: Traditional Ecological Knowledge and Western Science through the Lens of Extension Agents in a Pastoral Region

Those involved in sustainability debates on developmental pathways concur in the synergistic potential of integrating traditional ecological knowledge (TEK) and Western scientific approaches. Transhumant pastoralism is a livelihood strategy adapted to spatiotemporal environmental variability in many mountainous and arid regions worldwide. This form of livelihood is based on a mobile logic that is increasingly threatened by novel lifestyles promoted from a Western mind-set and by climate change. The aim of this article is to identify and characterize the different perspectives of environmental and social issues in a pastoral region and their association with labor collaboration among extension agents, framed in an institutional action. We tackled the inquiry about viewpoints with Q methodology and related it to regional problems, alternative solutions, and future development pathways for transhumant pastoralism and landscape management in northwest Patagonia. We identified six perspectives and characterized them with their topological position in the social network. Mediating positions registered the highest network centrality of labor collaborations among agents, whereas more dominant perspectives emphasizing TEK or scientific knowledge registered intermediate centrality. There was consensus on the need for sustainable developmental options, but the emphasis on combining knowledge still needs convergent solutions.     

The interplay between formal project memberships and informal advice seeking in knowledge-intensive firms: A multilevel network approach

In this study we investigate the interplay between knowledge workers’ formal project team memberships and their informal interactions from a multilevel network perspective. Conceptualizing knowledge workers’ affiliation with project teams as a membership network and their interactions as an advice network, we discuss how shared project team memberships as well as multiple memberships influence patterns of informal exchange in knowledge-intensive organizations. To empirically determine the impact of formal organization on informal exchange we apply exponential random graph models for multilevel networks to relational data collected on 434 R&D employees working on 218 project teams in a high-tech firm in Germany. Our results show that employees sharing project memberships create advice ties to each other but do not exchange advice reciprocally. In addition, we find a negative relationship between having a high number of project memberships and informally seeking or providing advice.     

On the core of characteristic function games associated with exchange networks

An exchange network is a social system in which the actors gain valued resources from bilateral transactions, but an opportunity to negotiate a deal is given only to those pairs of actors whose positions are tied with each other in a fixed communication network. A transaction consists in a mutually agreed-on division of a resource pool assigned to a network line. An additional constraint imposed on such a network restricts the range of transaction sets which may happen in a single negotiation round to those consistent with a given “exchange regime.” Under the one-exchange regime every actor is permitted to make no more than one deal per round. Bienenstock and Bonacich [Bienenstock, E.J., Bonacich, P., 1992. The core as a solution to exclusionary networks. Social Networks 14, 231–243] proposed to represent a one-exchange network with an n-person game in characteristic function form. The aim of this paper is to develop a mathematical theory of games associated with homogenous one-exchange networks (network homogeneity means that all lines are assigned resource pools of the same size). The focus is on the core, the type of solution considered most important in game theory. In particular, all earlier results obtained by Bonacich are re-examined and there is given a new graph-theoretic necessary and sufficient condition for the existence of nonempty core for the game representing a homogenous one-exchange network.     

Hospital social workers' assessment processes for children at risk: positions in and contributions to inter-professional teams

This article explores hospital social workers' assessment processes for children at risk within the context of inter-professional teams working in child hospital care in Sweden. Based on qualitative interviews, the study discusses how assessment processes for children at risk can be understood from a professionalism perspective. Three institutionalized norms—juridical, therapeutic, and medical, building on different knowledge systems—are analyzed in relation to the three positions taken by hospital social workers as team members—active, reflective, or passive—leading to different kinds of actions in the assessment processes. The outlined norms and the positions taken involve consequences for the children and their families, but also pose questions for the future professionalization efforts of hospital social work.     

A Nash bargaining model for simple exchange networks

Starting from exogenously given negotiation networks, sociological exchange theories explain bilateral divisions of fixed surpluses (e.g., cake, dollar) as consequences of the partners’ structural embeddedness. In accordance with the available experimental evidence, we focus on simple exchange networks and present a formal model for predicting profit splits from such structures. In contrast to other approaches, we combine the generalized Nash bargaining solution from game theory with the assumption that both relational features and network positions affect exchange outcomes. The resulting point predictions for profit splits correspond closely with experimental results obtained by Cook et al. [Cook, K.S., Emerson, R.M., Gillmore, M.R., Yamagishi, T., 1983.

Theoretical Comparisons of Forms of Exchange

A recent program comparing negotiated and reciprocal forms of social exchange offers important implications for theory development. Results of these investigations show that the form of exchange studied—negotiated or reciprocal—affects many of the processes and assumptions underlying contemporary theories of exchange. Three such effects are discussed here. First, the form of exchange affects the causal mechan– isms underlying power use and the relation between network structure and power. Second, whether exchange is negotiated or reciprocal affects the relative emphasis on learning or rational–choice models and the breadth of motivations assumed for "self–interested" actors, including reward maximization, loss avoidance, and reciprocity. Third, the form of exchange affects the salience of the cooperative and competitive "faces" of exchange, influencing actors' subjective xperiences with exchange. These results show the limitations of theories based on any single form of exchange and the need for greater understanding of the full range of exchange forms that characterize social life.     

Old friends and new acquaintances: Tie formation mechanisms in an interorganizational network generated by employee mobility

This study investigates mechanisms of tie formation in an interorganizational network generated by the mobility of employees between organizations. We analyze a data set that contains information on all organizations in the Stockholm metropolitan area between 1990 and 2003. We show that the formation of new ties is contingent upon the direction of past ties, and that most connections occur at an intermediate geodesic distance of 2 and 3. The findings highlight the importance of tie direction and indirect connections in research on network dynamics and knowledge exchanges stemming from the mobility of employees across organizations.     

DOES WHOM YOU KNOW MATTER? UNRAVELING THE INFLUENCE OF PEERS' NETWORK ATTRIBUTES ON ACADEMIC PERFORMANCE

This paper examines how students' network size, distance, prestige, and connections to influential individuals impact academic performance. Larger and closer networks facilitate information exchange, but may also increase distractions that decrease productivity. We resolve this ambiguity using administrative data from a business school that features random assignment of students to multiple overlapping sets of peers, allowing us to calculate degree, closeness, eigenvector, and Katz‐Bonacich centrality for each node. We find that increasing closeness centrality within the network negatively affects student performance measured by grade point average, suggesting that synergy reduction and information processing costs outweigh benefits from greater information access.
