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.     

Theories of network exchange: Anomalies,desirable properties,and critical networks

The present study evaluates four well-known theories of exchange in networks. In previous research these theories’ predictions were compared for a small set of networks using experimental data. We compared their predictions for all 12,112 networks up to size 8. By comparing these predictions we (i) identified anomalies in theories of network exchange, (ii) investigated to what extent the theories satisfy basic principles of exchange, (iii) identified ‘critical’ networks for which predictions are very different. We conclude that exchange in networks is not yet well understood.     

The Exclusiveness of the Political Field: Networks and political mobilization

This paper applies social network analysis to three case study social movement organizations based in the north of England: a local Labour Party branch, an environmental group, and a conservation group. Using a postal survey of members, we chart the extent of ties between members of these three groups, indicating how each group has its own internal social dynamics and characteristics that are related to the nature of the movement organizations themselves. We explore how the network structures interrelate with the socio-demographic structure of the membership of the three organizations, and we show there are important differences in the way that core members of the three organizations are recruited compared to those who are either peripheral or isolated. Our paper is the first to analyse the networks of whole populations of case study organizations in the UK, and can therefore be read as developing the potential of social network analysis for case study research and for understanding social movements. Analytically we argue it is important to distinguish two different types of ways that networks are important. They can be seen as offering resources for mobilization, or they can be seen as providing a means of integrating particular types of individuals into organizations. It is this latter sense that offers a more fundamental role for network analysis, and we argue that it offers an important way of developing insights from resource mobilization theory by relating them to Bourdieu's provocative arguments regarding the exclusiveness of the political field.     

Consumer Culture,Taste Preferences,and Social Network Formation

One of the most important and consistent findings in the social networks literature is that individuals are socially connected to people who resemble themselves. This finding extends to preferences for consumer culture. Whereas network theorists previously had presumed that social networks generated this outcome through a process of social influence, this traditional conception of the relationship between culture and social networks has been challenged by new theoretical perspectives and novel methodological techniques that enable researchers to empirically test the causal direction of the relationship. In this article, I first discuss how theorists have adjudicated between competing explanations of the relationship of taste preferences and social network structure. Second, I discuss how sociologists have theorized that tastes contribute to variation in network structure. Third, I examine survey and ethnographic research that discusses interactional mechanisms by which people actively mobilize culture to form social relationships. Fourth and finally, I discuss research that explores how consumer culture constitutes the meaning of social relationships and how relationship category affects theorizing of network formation.     

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.     

Social and Personal Coping Resources,Functional Impairment,and Perceived Health Status Among Mexican-Origin Elders

Abstract

This study explores the contributions of social and personal coping resources to selfreported health among Mexican-origin elders. While these resources have been studied previously in the general population, less is known about how they operate in Mexican-origin Americans. The authors used data from the Hispanic Established Populations for the Epidemiological Study for the Elderly (HEPESE), a longitudinal survey of 3,050 Mexican Americans to examine the effects of social and personal coping resources on selfreported health two years later. The results of the ordered logistic regression analysis indicated that personal coping resources were a significant predictor of better selfreported health. Social coping resources approached significance. Neither of these resources, however, mediated or moderated the considerable relationship between functional impairments and perceived, selfreported health. Implications for practice and further research are discussed.     

Place,space, networks,and the sustainability of collective action: the Madres de Plaza de Mayo

This article provides a framework for analysing social movements and explaining how collective action can be sustained through networks. Drawing on current relational views of place and space, I offer a spatialized conception of social networks that critically synthesizes network theory, research on social movements, and the literature on the spatial dimensions of collective action. I examine the historic and contemporary network geographies of a group of human rights activists in Argentina (the Madres de Plaza de Mayo) and explain the duration of their activism over a period of more than two decades with regard to the concept of geographic flexibility. To be specific, first I show how, through the practice of place‐based collective rituals, activists have maintained network cohesion and social proximity despite physical distance. Second, I examine how the construction of strategic networks that have operated at a variety of spatial scales has allowed the Madres to access resources that are important for sustaining mobilization strategies. Finally, I discuss how the symbolic depiction of places has been used as a tool to build and sustain network connections among different groups. I conclude by arguing that these three dimensions of the Madres’ activism account for their successful development of geographically flexible networks, and that the concept of geographic flexibility provides a useful template for studies of the duration and continuity of collective action.     

Positive Emotions,Instrumental Resources,and Organizational Network Evolution: Theorizing via Simulation Research

In the workplace, people seek positive emotional experiences as well as instrumental resources while doing their work. Yet we know little about how affective micro-dynamics drive the evolution of organizational networks, influence network trajectories, and determine macro outcomes such as collective affect and overall network structure. Given the lack of theory on affective micro-dynamics and network evolution, we propose a model that includes both affective and instrumental micro-mechanisms and use simulation methods to explore evolutionary dynamics and develop new theory. The core of our model is the empirically observed tendency for people to forego the acquisition of instrumental resources to avoid a decrease in positive emotion when choosing interaction partners. We conduct “experiments” with the simulation, considering the effects of the tradeoff, dispositional affect, resource inequality, and ingroup favoritism. The results show that dispositional affect and the tradeoff have considerable effects on network trajectories, collective affect, and resource transfer. We provide new theoretical propositions about affect in organizations.     

It's not who you know,it's how you know them: Who exchanges what with whom?

Reciprocity – doing for others if they have done for you – is a key way people mobilize resources to deal with daily life and seize opportunities. In principle, reciprocity (the Golden Rule) is a universal norm. In practice, it is variable. Personal networks rarely operate as solidarities and as such, people cannot count on all the members of their networks to provide help all the time. Rather, social support comes uncertainly from a variety of ties in networks. This paper uses survey research to understand the variable and contingent nature of reciprocity and inquires about the kinds of resources exchanged between people. We investigate the extent to which interpersonal ties, network characteristics, and people's personal characteristics (e.g., gender) affect the nature of reciprocal relationships. The evidence is extraordinarily clear on one subject – giving support is strongly associated with getting it. Analyses show that getting support from network members is the key to East Yorkers reciprocating – usually in kind but sometimes with other forms of support.     

The Impact of the Worker: How Social Capital and Human Capital Influence the Job Tenure of Formerly Undocumented Mexican Immigrants

Using the 1992 Legalized Population Survey, I focus on employment matching processes of formerly undocumented Mexican immigrant workers in the United States. As in earlier studies, I show that employment characteristics are related to the job tenures of immigrant workers. However, my contribution is that I specifically analyze how formerly undocumented Mexican immigrant workers' attributes and social networks influence their job tenures. In general, increases in human capital are associated with shorter job tenure, apparently in an effort to improve employment conditions, while the use of social capital is positively related with job tenure. It appears that acquiring employment is a social process, and those using personal networks find longer lasting jobs. Although prior studies have minimized the role of supply-side characteristics such as employees' skill level and social networks in influencing job tenure, my research confirms the significance of workers and the resources they bring to the labor market.     

Personal Social Networks of Women with Co-Occurring Substance Use and Mental Disorders

ABSTRACT

There has been relatively little examination of the social network resources of women with substance use disorder, and even fewer explorations of women with co-occurring mental disorders, such as anxiety, depression, and posttraumatic stress disorder. This study explores the nature of co-occurring mental disorders, social network characteristics and perceived social support in 136 women with substance use disorders. Respondents reported small personal networks that contained both supportive and non-supportive people. Relatives did provide social support, but those who used alcohol/drugs were viewed as tending to interact negatively. Women with dual disorders perceived less concrete, emotional, and sobriety support from some network relationships than the women with substance use disorders only. Implications for research and practice are presented.     

Keep around,drop, or revise? exploring what becomes of difficult ties in personal networks

Previous studies increasingly recognize the presence and impact of difficult individuals within personal networks. However, current research sheds little light on the turnover, retention, and change in quality of such difficult ties. The current study addresses this gap by focusing on two distinct forms of network change. We examine how role relationships, support exchange, relational homophily, and personal characteristics are associated with these processes. Data are drawn from three waves of the University of California Social Network Study (UCNets), a project containing comprehensive longitudinal data on ego networks among two adult cohorts. Findings indicate that over time, 34% of difficult ties re-appear in people’s networks as sources of aggravation; 26% of difficult ties are removed from the network; and 40% can no longer be verified as problematic network members. Most ties no longer deemed difficult are identified as providing one or more supportive functions. Multinomial multilevel models reveal that exchanging support tends to anchor difficult ties in the network. Kinship, meanwhile, plays a large role in whether difficult ties remain or get dropped. Personal characteristics such as gender, income, and relocation also play a role in these processes. Overall, we conclude that the turnover dynamics of difficult ties are similar to other ties, and the apparent change from negative to positive suggests that many ties hold ambivalent properties that make shedding such ties less common than may be expected.     

Interorganizational network findings from a nationwide cardiovascular disease prevention initiative

ObjectivesTo use network analysis in order to evaluate the effectiveness of interorganizational networks in implementing policy, systems, and environmental interventions for cardiovascular disease prevention throughout the United States.MethodsEvaluators conducted an interorganizational network (ION) survey to examine information sharing and joint planning within organizational relationships in 15 community-based cardiovascular disease prevention partnership networks. Density and betweenness centrality scores at the node- and network-level were calculated for each partnership network using UCINET© network analysis software. Common data patterns were then extracted using a multiple case study format.ResultsNetwork density scores ranged from 0.50 to 1.00 (M = 0.84, SD = 0.14) for information sharing and 0.43–1.00 (M = 0.77, SD = 0.15) for joint planning. Centralization indices ranged from 0.00 to 0.11 (M = 0.04, SD = 0.03), and 0.00-0.17 (M = 0.06, SD = 0.05), respectively. Overall, 73.33 % of communities were successful in meeting their partnership goals.ConclusionsWhen planning and implementing interorganizational networks, high betweenness centrality and more hierarchically structured networks were identified as the most salient partnership characteristics to programmatic success. The network findings were triangulated with previously published qualitative data to provide context. These findings provide valuable insight on how national networks can be designed and leveraged to implement systematic community health projects.     

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.     

Social Networks of Old People in India

Summary

This article presents a comparative analysis of the available research on the social networks of older persons in India. Most of this research has been done in North Indian cities. The research foci of the available studies include network size, core networks and beyond, life course changes in networks, impacts of residency in old-age homes, gender differences, and joint and nuclear family residence. This research is discussed in terms of its policy implications. Because the research demonstrates that social networks are important for the welfare of older Indians, one can conclude that social policy that encourages the maintenance of robust networks throughout the life course may be worth pursuing. One aspect of policy is discussed. The analysis of the relationship between social network and gender suggests that current policies that can be seen as supporting gender inequality in terms of property may have a negative impact on the networks of older women.     

Making connections between global production networks for used goods and the realm of production: a case study on e‐waste governance

Recent scholarship on waste within economic geography and global production network (GPN) studies has identified several unique characteristics of networks for used goods vis‐à‐vis ‘traditional’ GPN studies focused on production, exchange and consumption. However, in un‐bracketing GPNs to include analysis of post‐consumption activity, identifying how the distinct moments of production, exchange, consumption and disposal/recycling are related becomes a crucial task. Towards this end, I present a case study on the governance of e‐waste networks that draws upon discussions of performativity and Hudson's cultural political economy approach to GPNs. In my analysis, I demonstrate how multiple factors, such as ideological differences over how to handle e‐waste, the non‐standardized nature of used goods, as well as production factors such as design choices and planned obsolescence, all shape and disrupt efforts to standardize and coordinate resource recovery and hazard mitigation in the post‐consumption phase of electronic goods. Such analysis moves past the novelty of GPNs for used goods toward a more integrated understanding of GPNs as a whole.     

Bringing about social justice through feminist research for monitoring,evaluation, and learning? A conversation from Oxfam GB

ABSTRACT

At Oxfam, we have spent much of the last two years talking about feminist principles. In the context of the #Metoo and #Aidtoo movements, the presence (or absence) of these feminist values and principles is increasingly – and rightly – under the spotlight. In this article, we reflect on what it takes to embed these values in our research practice within the monitoring, evaluation, and learning (MEL) function of an international non-government organisation such as Oxfam. These values shape our understanding of the purpose of carrying out MEL activities as a tool for bringing about social justice, through examining gender and power relations, why they exist and how they change. We reflect on the successes and challenges we have faced while utilising evaluation for greater gender equality. By doing so, we aim to start shedding light on the structural changes needed to bring about social changes through MEL, and research more broadly.     

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.     

Microsocial Implications of the Macrostructural Distribution of Social Resources

Abstract

The general purpose of this paper is to develop an explanation of how the macrostructural distribution of social resources affects the microsocial structure of personal social networks and, therefore, constraints on individual purposive action.

Specifically, the paper attempts to provide a theoretical integration for two sets of recent findings; those noting status-related variations in personal network structures and those noting differential success in occupational attainment as a function of personal network structure and use.

It is suggested that the effects of macrosocial and microsocial structure on purposive action in general can now be understood using a social resources perspective.
