This naturalistic pre-test/post-test field experiment studied a university public relations campaign, the “Great Cities Initiative,” for evidence of priming or framing effects on newspaper reporters and editors. The phrase “great cities” in the Chicago Tribune increased 433% during the 16-month post-test, but only 26% of stories identified the campaign source. Several measures of semantic network diversity increased, also supporting priming over framing effects.  相似文献

Why do some contagions “go viral” and others do not? Research on “small world” networks (Watts and Strogatz, 1998) shows how a very small number of long-range ties that bridge between clusters can allow contagions to spread almost as rapidly as on a random network of equal density. Recent research shows how long-range ties that accelerate the spread of information and disease can impede the spread of complex contagions—behaviors, beliefs and preferences that diffuse via contact with multiple adopters ( Centola and Macy, 2007). In confirming this result analytically and extending the analysis from small world to power law networks, we discovered that complex contagions require a critical mass of infected nodes that corresponds to a phase transition in the ability of the contagion to take advantage of the “shortcuts” created by long-range ties. We demonstrate how this critical mass is related to the dynamics of the contagion process and identify implications for modeling behaviors that spread via social influence, such as viral marketing and social movements.  相似文献

In this paper we measure “control” of nodes in a network by solving an associated optimisation problem. We motivate this so-called VL control measure by giving an interpretation in terms of allocating resources optimally to the nodes in order to maximise some search probability. We determine the VL control measure for various classes of networks. Furthermore, we provide two game theoretic interpretations of this measure. First it turns out that the VL control measure is a particular proper Shapley value of the associated cooperative network game. Secondly, we relate the measure to optimal strategies in an associated matrix search game.  相似文献

Focusing on gender inequality in a local community elite, we investigate the role of gender in access to and participation in networks of nonprofit trustees in Louisville, Kentucky. We examine two types of network relations: participation in the network of overlapping board memberships (the structural network) and interpersonal ties of collegiality and friendship (the social network). Asking whether the gender hierarchy found in most private and public sector organizations is mirrored in this inner circle of trustees, with men occupying the most influential positions in the structural and social networks, we find some male advantage in the structural network. Men predominate in holding most board seats, occupying multiple board seats, and in having slightly greater network centrality. By contrast, women hold the edge in the social network, with slightly greater centrality and higher levels of social integration. Women's disadvantage in the structural network is at least partly counterbalanced by their prominence in the social network of trustees in Louisville. Results indicate that the local nonprofit sector includes a small number of women (but no people of color) in leadership roles.  相似文献

This article contributes to the study of “duality” [Breiger, R., 1974. The duality of persons and groups. Social Forces 53, 181–190] in social life. Our study explores multi-level networks of superposed and partially connected interdependencies, the first being inter-organizational, the second inter-individual. We propose a method of structural linked design as an articulation for these levels. First, we examine separately the complete networks at each level. Second, we combine the two networks in relation to one another using systematic information about the membership of each individual in the first network (inter-individual) to one of the organizations in the second network (inter-organizational), as in bipartite networks. This dual positioning, or the linked design approach, is carried out in an empirical study examining performance variations within the “elite” of French cancer researchers in 1999. By looking at measures of centrality, we identify the actors that these top researchers consider as central or peripheral at the inter-individual level (the big and the little fish among the elite), and the laboratories that the research directors consider as central or peripheral at the inter-organizational level (the big and the little ponds among all the laboratories conducting cancer research in France at that time). In addition to the rather trivial report of the competitive advantage of big fish in big ponds (particularly because of the advantage of size for laboratories in this field), we use measurements of scientific performance to identify “catching up” strategies that the smallest fish use in this system. We suggest that this method offers new insights into the duality and multi-level dimension of complex systems of interdependencies, and also into the ways in which actors manage these interdependencies. We believe that it adds a new dimension to the sociological exploration of the determinants of performance, of meso-level phenomena such as opportunity structures and institutional change, or of macro-level phenomena such as social inequalities.  相似文献

Measuring ‘neighborhood’: Constructing network neighborhoods   总被引:1,自引:0,他引:1  
This study attempts to measure neighborhood boundaries in a novel way by creating network neighborhoods based on the density of social ties among adolescents. We create valued matrices based on social ties and physical distance between adolescents in the county. We then perform factor analyses on these valued matrices to detect these network neighborhoods. The resulting network neighborhoods show considerable spatial contiguity. We assess the quality of these aggregations by comparing the degree of agreement among residents assigned to the same network neighborhood when assessing various characteristics of their “neighborhood”, along with traditional definitions of neighborhoods from Census aggregations. Our findings suggest that these network neighborhoods are a valuable approach for “neighborhood” aggregation.  相似文献

Recently, there has been increasing interest in determining which social network structures emerge as a consequence of the conscious actions of actors. Motivated by the belief that “networks matter” in reaching personal objectives, it is a natural assumption that actors try to optimize their network position. Starting from the notion that an optimal network position depends on the social context, we examine how actors change their networks to reach better positions in various contexts. Distinguishing between three social contexts (a neutral context, a context in which closed triads are costly, and a context in which closed triads are beneficial), theoretical results predict that emerging networks are contingent on the incentives that are present in these contexts. Experiments are used to test whether networks that are theoretically predicted to be stable are also stable experimentally. We find that emerging networks correspond to a large extent with the predicted networks. Consequently, they are contingent on the incentives present in various social contexts. In addition, we find that subjects tend to form specific stable networks with a higher probability than predicted, namely, efficient networks and networks in which everyone is equally well off.  相似文献

When a pair of individuals is central to a research problem (e.g., husband and wife, PhD student and supervisor) the concept of “duocentered” networks can be defined as a useful extension of egocentered networks. This new structure consists of a pair of central egos and their direct links with alters, instead of just one central ego as in the egocentered networks or multiple egos as in complete networks. The key point in this kind of network is that ties exist between the central pair of egos and between them and all alters, but the ties among alters are not considered. Duocentered networks can also be considered as a compromise between egocentered and complete networks. Complete network measurements are often costly to obtain and tend to contain a large proportion of missing data (especially for peripheral actors). Egocentered network data are less costly but a lot of information is lost with their use when a pair of individuals is the relevant unit of analysis.  相似文献

Technology continues to challenge the public relations practitioner to find ways to inform key constituents. The new technology has given rise to the “new journalism” that includes a declining traditional media and exploding internet media filled with websites and bloggers. The question posed by this research asks: Does the public relations practitioner inherit the same protection offered by “qualified privilege” that is most often associated with the traditional “press” or “reporter?” The research lays a foundation with an examination of defamation and the defense of qualified privilege. The research concludes that if information gathered by the public relations practitioner meets the “intent” and “content” tests, the information qualifies as news. Passing the “news” test, the defense of “qualified privilege” also attaches to the public relations practitioner.  相似文献

The April-June 2002 issue of Sociologie du Travail opened its pages for a discussion of the question of quality. Authors highlighted two mechanisms: “identification/singularization” (a sociotechnical process of co-constructing the quality of goods and services) and evaluation (a process of building up confidence so as to do away with uncertainty about the quality of goods and services). Can these two processes be analyzed together? If so, how to understand their interactions? As the example of managing the water supply and wastewater shows, jointly analyzing these two processes helps us understand the work of “qualification/requalification”. The relation between singularization and evaluation is clarified by introducing the notion of a “regime of government”.  相似文献

A semantic network analysis of keywords in titles of studies published in Public Relations Review and the Journal of Public Relations Research was conducted to determine the salient keywords in public relations scholarship from 1975 to 2011. “Communication,” “PR,” “public,” “practitioner,” and “corporation” have been the most prominent keywords, and the association of “PR-practitioner” was the most salient keyword association in public relations scholarship consistently.  相似文献

The issue of the influence of norms on behavior is as old as sociology itself. This paper explores the effect of normative homophily (i.e. “sharing the same normative choices”) on the evolution of the advice network among lay judges in a courthouse. 0020 and 0025 social exchange theory suggests that members select advisors based on the status of the advisor. Additional research shows that members of an organization use similarities with others in ascribed, achieved or inherited characteristics, as well as other kinds of ties, to mitigate the potentially negative effects of this strong status rule. We elaborate and test these theories using data on advisor choice in the Commercial Court of Paris. We use a jurisprudential case about unfair competition (material and “moral” damages), a case that we submitted to all the judges of this court, to test the effect of normative homophily on the selection of advisors, controlling for status effects. Normative homophily is measured by the extent to which two judges are equally “punitive” in awarding damages to plaintiffs. Statistical analyses combine longitudinal advice network data collected among the judges with their normative dispositions. Contrary to what could be expected from conventional sociological theories, we find no pure effect of normative homophily on the choice of advisors. In this case, therefore, sharing the same norms and values does not have, by itself, a mitigating effect and does not contribute to the evolution of the network. We argue that status effects, conformity and alignments on positions of opinion leaders in controversies still provide the best insights into the relationship between norms, structure and behavior.  相似文献

The far-reaching effects of the social systemic division of labor on the organization and contents of primary ties make the Community Question an important issue for many sociologists. This paper looks at the personal embeddedness of families in three German cities (Berlin, Hamburg, and Stuttgart) and examines the Community Question with data collected at the end of 2003. It is based on the theoretical views of Wellman [Wellman, B., 1979. The community question. The intimate networks of East Yorkers. American Journal of Sociology 84, 1201–1231], who used a network analysis perspective to conceptualize “the Community Question”. The results of this German study generally support the results of Wellman's second East York Study. However, the network structures analyzed in my study vary from the three ideal-type models. Cluster analysis shows that Wellman's typology can be replicated relatively well in Germany. In contrast to traditional discourse related to the Community Question, particular network types are not associated with low levels of social relations. Moreover, structural factors do not explain the existence of different network types. Thus, the networks are not a product of only one community model. They suggest that it is less helpful to talk about “Saved”, “Lost”, or “Liberated” communities than it is to regard communities as a mixture of strongly-knit nuclear clusters and of broader, sparsely-knit relations that provide access to different groups and their resources.  相似文献

In recent years, research examining determinants and consequences of the means-tested child care subsidy program (the Child Care and Development Fund [CCDF]) has grown dramatically. To measure subsidy utilization, existing studies typically rely on parent-reported measures of subsidy receipt drawn from large surveys. As the research literature on child care subsidies has grown, however, so have concerns about the trustworthiness of parent-reported subsidy use. One way to assess the quality of parent-reported subsidy use is to examine its overlap with another subsidy receipt measure, drawn from a different source. The current paper uses the Fragile Families and Child Well-Being Study (FFCWS), the only existing survey data source that contains an alternate measure of subsidy receipt — based on child care provider report — which permits a comparison to parent-reported measures. We find evidence that increases our confidence in the trustworthiness of parents as accurate reporters of subsidy receipt. In recognition that neither data source reflects “true” subsidy receipt, however, we conclude with a discussion of limitations and steps for future research.  相似文献

How to test for the existence of a new model of production based on the firm lending an ear to customer demands and valuing the individual and collective intelligence of its work force? The facts for putting this model to the test of reality come from an analysis of two Argentinean automobile-makers, subsidiaries of Toyota and Volkswagen. Various aspects of their organization policy provide evidence of their capacity for making adaptations by “hybridizing” the parent firm’s model with the rationales inherent in the network of local actors (suppliers and labor unions, in particular). These firms are open systems with a narrow margin of maneuver. — Special issue: Latin America.  相似文献

This study explored the development of a short version of “ASK” (Attitude–Skills–Knowledge) Scale — a tool for caseworkers and supervisors self-assessing cultural competency in a training context. The goal was to determine the validity and reliability of the 97-item long form and find factors to consolidate the items to create a shorter tool for training and practice use. In a state project, 171 caseworkers and supervisors rated the level of importance of 97 areas of attitudes, skills, and knowledge competency in terms of self-assessing their readiness to work in a culturally diverse environment. Attitude, skill, and knowledge domains of the instrument were tested with high reliability (.93 for the 30 “attitude” items, .95 for the 40 “skill” items, and .92 for the 27 “knowledge” items). Factor analyses indicate that this scale can be efficiently applied to categorize the 30 attitude items into eight factors, the 40 skill items into nine factors, and the 27 knowledge items into seven factors. With these 24 factors, a short ASK version was constructed for future research to encourage continuous self-assessment.  相似文献

Respondent-driven sampling (RDS) is currently widely used for the study of HIV/AIDS-related high risk populations. However, recent studies have shown that traditional RDS methods are likely to generate large variances and may be severely biased since the assumptions behind RDS are seldom fully met in real life. To improve estimation in RDS studies, we propose a new method to generate estimates with ego network data, which is collected by asking respondents about the composition of their personal networks, such as “what proportion of your friends are married?”. By simulations on an extracted real-world social network of gay men as well as on artificial networks with varying structural properties, we show that the precision of estimates for population characteristics is greatly improved. The proposed estimator shows superior advantages over traditional RDS estimators, and most importantly, the method exhibits strong robustness to the recruitment preference of respondents and degree reporting error, which commonly happen in RDS practice and may generate large estimate biases and errors for traditional RDS estimators. The positive results henceforth encourage researchers to collect ego network data for variables of interests by RDS, for both hard-to-access populations and general populations when random sampling is not applicable.  相似文献

Though foreign workers served to overcome the labor shortage in the Malaysian construction market, over-dependence on foreign workers and the negative impacts induced have become a serious social problem. The aims of this research are to identify those negative impacts induced by foreign workers in the Malaysian construction market and to determine strategies in minimizing these negative impacts. Data were collected through a structured interview and survey. The questionnaires were delegated to professionals in construction projects who have direct contacts with foreign workers. Only respondents from those companies registered under the CIDB grade G7 were chosen for this survey. There were 117 sets of questionnaires completed and analyzed through the structured interviews. The three principal factors attracting foreign workers to the Malaysian construction market are “Preference of the employers”, “Lifestyle and working conditions”, and “Unattractiveness of the career pathway”. The main negative impacts induced by foreign workers are “Over-dependence on foreign workers”, “Increment in criminal activities or social problems”, and “Existence of illegal workers”. This research proposes that strategies such as “Attract local workers into the construction industry”, “Industrialized Building Systems”, “Eliminate illegal migration”, and “Improve governance structure” would be successful in minimizing negative impacts induced by foreign workers.  相似文献

This analysis of the mobilization of American artists against the war in Iraq emphasizes how their work situations have shaped their involvement. Regardless of political organizations and networks, or of the ideological dimensions of the anti-war cause, relations having to do with the work and occupational identities of these persons determined, in the first place, their actions and the positions they have adopted publicly. This article contrasts various “artistic subfields” and “patterns of activity” in order to understand the factors that have made it more or less tenable for these social actors to articulate the identities of artist and activist and, in some cases, to produce “political art”. The second part focuses on the “professional structuring” of this activism by showing how the current operation of artistic spheres — which have become more self-regulated, specialized and professionalized —tend to curb the confusion of issues that mixes aesthetic up with politics.  相似文献

While the terms soft power, public diplomacy (PD) and nation brands have cemented their place in academic discourse during the early 21st century, the evaluation of these activities has not been given anywhere near the same level of attention. When describing how campaigns are evaluated, scholars tend to make assumptions based on the goals or outputs of an initiative rather than on the basis of reliable, empirical data on its results. Strong positivist tendencies within current scholarship usually lead to evaluation being considered in terms of methodology and best practice, typically with the assumption that certain preferred outcomes will be demonstrable if an ideal model is followed. Most significantly, such approaches seem to underplay the interests and objectives that inform and constrain choices surrounding modes of communication and evaluation. I argue here that PD activities are rarely the product of rational choices about communication options, and nor is PD evaluation the result of applying the “best” methodology. Rather, questions of PD and evaluation practices are bound together in complex organizational and power structures that generate pragmatic responses both to the “problem of influence” and the reporting of results. Through use of the concept of articulation, this article outlines a framework for interpreting evaluation practices from a contextualized perspective, which grasps how and why soft power practices assume certain forms.  相似文献
