The tie effect on information dissemination: the spread of a commercial rumor in Hong Kong

The ability to acquire information has been considered a crucial factor facilitating instrumental actions, such as job search and organizational innovation. Previous social network studies tend to treat the characteristics of social ties through which information is acquired as causes that may affect instrumental outcomes. However, little research has directly examined the spread of information via social ties and the tie effect on information dissemination. Using telephone survey data collected after the outbreak of an extensive commercial rumor in Hong Kong, the present paper investigates the characteristics of social ties through which the information is spread and the tie effect on information dissemination. Results show that while mass media, particularly television, serves as a major channel of information flow, social ties are also widely used. Individuals tend to share information with strong ties, or people with whom they perceive to have good relations. However, information transmitted via kin ties tends to arrive at the respondent faster than via nonkin ties or other communication channels. Implications of the findings are discussed.     

Vorwort

Although the concept of tie strength plausibly extends opinion leadership theory, prior studies have indicated that tie strength is of minor importance for opinion leadership. The paper argues that strong ties and weak ties play major roles in the process of opinion leadership that prior studies have insufficiently differentiated due to methodological limitations. Against this background, a methodologically more rigorous reassessment of the association between tie strength and opinion leadership is conducted. The reassessment centers on the combination of ego-centered network analyses with statistical methods of multilevel analysis. These are applied to original data of a study by Schenk (2006) on financial opinion leadership in Germany (n?=?10,100 survey respondents) which has previously been considered as an important indication for tie strength’s minor importance. Empirical results show that strong ties and weak ties are remarkably more important in the process of opinion leadership than previously known. Opinion leaders benefit from strong ties, because personal influence can be carried through them comparatively easily. By contrast, weak ties foster opinion leadership in a structural manner by catalyzing the influence that opinion leaders can exert through strong ties.     

Don’t mention it: Why people don’t share job information,when they do,and why it matters

Network-based job search is especially likely to foster workplace segregation and limit status attainment when information flows through homophilous ties. This paper takes the perspective of information holders and examines how the use of strong versus weak ties – which tend to be homophilous and heterophilous, respectively – differs with characteristics of labour markets in which jobs are located. Using in-depth interviews with entry-level white collar workers I show that information holders with opportunities to mention specific jobs to specific people do so only 27% of the time. Because they hesitate to share information if they are uncertain the information is specifically sought, information flows more commonly to strong ties, whose career goals are more likely to be known. Information is more likely to be shared with weak ties if it concerns occupations for which one may be specifically credentialed, since receiving relevant training serves as signal of interest in such jobs. These finding suggest that the homophily of referrals and their inequality-generating effects may vary across occupations.     

Social Capital,Labour Markets,and Job‐Finding in Urban and Rural Regions: comparing paths to employment in prosperous cities and stressed rural communities in Canada1,2

This paper compares paths to employment (job‐finding) in prosperous cities and economically‐stressed rural communities in Canada. Since the pioneering work of Mark Granovetter (1973; 1974 ), sociologists have investigated the role of social capital in job‐finding (specifically, the use of strong and weak social ties to find out about employment opportunities). To date, however, there have been few direct comparisons of job‐finding in urban and rural settings (see Lindsay et al., 2005 ; Wahba and Zenou, 2005 ). Using data from two major surveys and a qualitative interview project, we uncover several important differences in urban and rural paths to employment. First, we find that both strong and weak ties are used more frequently by rural residents to find a job, while city‐dwellers rely more often on formal or impersonal means. Second, we find much stronger evidence of differentiation within rural regions. Long‐time rural residents are much more likely to use strong and weak ties to find employment than are newcomers. However, rural residents who used weak ties as paths to employment have significantly lower incomes. None of these patterns are evident in the cities. Together, these findings lead us to conclude that job‐finding in rural settings is strongly affected by constraints – in the labour market and in social capital resources – that are not present in cities.     

Social networks and Internet connectivity effects

This paper explores the impact of communication media and the Internet on connectivity between people. Results from a series of social network studies of media use are used as background for exploration of these impacts. These studies explored the use of all available media among members of an academic research group and among distance learners. Asking about media use as well as about the strength of the tie between communicating pairs revealed that those more strongly tied used more media to communicate than weak ties, and that media use within groups conformed to a unidimensional scale, showing a configuration of different tiers of media use supporting social networks of different ties strengths. These results lead to a number of implications regarding media and Internet connectivity, including: how media use can be added to characteristics of social network ties; how introducing a medium can create latent tie connectivity among group members that provides the technical means for activating weak ties, and also how a change in a medium can disrupt existing weak tie networks; how the tiers of media use also suggest that certain media support different kinds of information flow; and the importance of organization-level decisions about what media to provide and promote. The paper concludes with a discussion of implications for Internet effects.     

Not in our Backyard: Solidarity, Social Networks, and the Ecology of Environmental Mobilization

This paper explores the role of social networks in channeling individuals'involvement in local activism. A case study of a grassroots environmental group examines variation in members'levels of involvement, using three levels of explanation: individual attributes, strong and weak ties between members, and memberships in other organizations. After demonstrating that high- and low-level members are very similar in personal attributes, it focuses on social ties and organizational affiliations. As expected, the data suggest that an individual's level of involvement is increased by strong ties to other members, structural similarity to other high-level members, and fewer ties to nonmembers. Extramovement organizational affiliations are often assumed to diminish actors'structural availability, though empirical research in differential recruitment has generally revealed a positive effect on participation in social movements. This study addresses a microstructural explanation for the variation between competition and mutualism in a local multiorganizational field, as it shows how organizational goals condition the effect of outside affiliations on level of participation. Paradoxically, ties to other organizations with irrelevant goals appear to facilitate participation in this group, while ties to groups with congruent goals diminish participation.     

Bridging ties at the neighborhood level

This paper examines the relevance of the “strength of weak ties” model (Granovetter 1973) in devising community development strategies for urban neighborhoods. The policy implications of this model for activities designed to promote neighborhood identification and cohesion are outlined, and Granovetter's specific assumptions about the structure and functioning of urban neighborhood social networks are assessed in light of existing research. Little support is found for the presumed absence of bridging weak ties among urban neighbors, or for the assumption that strong ties create an obstacle to effective political mobilization in working-class neighborhoods. An alternative model of local-level integration is suggested, which retains Granovetter's concept of dense clusters of network ties linked by “local bridges”, but re-examines the role of weak ties in effecting such bridges.     

Work ties beget community? Assessing interactions among transnational private governance organizations in sustainable agriculture

Transnational private governance organizations (TPGOs) set standards for various sustainability issues and industries. TPGOs individually address only facets of larger problems such as land conversion, and competition among TPGOs also affects TPGO governance, meaning coordination across their activities can be required. Studies have shown that ties between TPGOs and other organizations facilitate information sharing, coordination and socialization. A systematic analysis of the structure of such ties, however, is lacking. Using the employment ties of staff and governors, we analyse the inter‐organizational communities of TPGOs that focus on agriculture. Our findings cast doubt on the existence of a coherent community of sustainable agricultural TPGOs: very few communities involve multiple TPGOs. While TPGOs with a similar product focus may form links with similar organizations, there are few direct and indirect ties among TPGOs. Researchers should therefore be cautious about assuming that a TPGO policy community crossing organizational and policy divides currently exists.     

The strength of weak conversational ties in the flow of information and influence

The “Strength of Weak Ties” theory is used to analyze the flow of information and influence in the network of conversational ties in a kibbutz community.The flow of six information items and two decision-making items was measured by indicators of communicative efficiency — speed, accuracy and credibility. The strength of ties activated and the direction of the flow (within groups or between groups) was analyzed.The findings reveal the actual, everyday functioning of weak ties as inter-group bridges, confirming the “Strength of Weak Ties” claim.The communicative advantages of weak ties are examined, applying structural analysis methods. The tendency of weak ties towards intransitivity and low multiplexity, is suggested to account for their frequent activation as inter-group bridges.The findings highlight the potential of social network analysis as a bridge between micro-level interaction and macro-level patterns including diffusion of innovation, formation of public opinion and social solidarity. Weak ties serve as the crucial paths between groups, thus providing the means by which individual behavior and ideas, originating in small face-to-face groups, are routinized and agglomerated into large-scale patterns.     

Strong or weak ties? British and Indian expatriate scientists finding jobs in Boston

In this article I analyse the different social networks that British and Indian scientists use to obtain job information in the pharmaceutical and biotechnology sector around Boston, Massachusetts. I argue that individuals' social networks are critical in helping highly skilled migrants find jobs. The research finds that British and Indian scientists use both strong and weak ties to obtain jobs and there is no significant difference between senior and junior workers in terms of whether they relied on strong or weak ties. I argue, nonetheless, that the terms strong ties and weak ties are problematic because they are not clearly understood or mutually exclusive.     

Prompting Depression Treatment Seeking among Smokers: A Comparison of Participants from Six Countries in an Internet Stop Smoking RCT

Websites containing information and advice about health are increasingly common and popular. It is important to understand whether the material these sites contain can positively influence individual behavior, and whether populations differ in their response to that material. Participants in an international web-based stop smoking randomized controlled trial (RCT) were screened for major depression; participants whose history and/or depression symptoms were deemed of concern were offered one of two prompts (Strong and Mild) to seek treatment, depending on depression history. Participants from 3 predominantly English-speaking and 3 predominantly Spanish-speaking countries were analyzed. Individuals given a Strong prompt were more likely to seek treatment for depression than those given a weak prompt (16.6% vs. 10.2% of previously untreated individuals reported seeking treatment), controlling for symptom level and other variables. Country-specific differences were observed, with participants from South Africa and Spain departing from the common pattern of Strong prompt leading to higher likelihood of treatment seeking. Older age and female gender, but not symptom level predicted higher likelihood of seeking treatment following a prompt. The results suggest that information provided by the health websites can promote help seeking in affected individuals.     

Social class,social networks and variety of weak and strong practices

Most research on the structural foundations of cultural consumption views tastes and practices as a better or worse emanation of social class or status. In contrast, this paper shows that cultural consumption is also embedded in a larger system of social networks. Not only does it examine whether having more diversified personal network translates into being involved in a wider range of cultural activities (omnivorousness), it also tests whether holding networks of different strength corresponds with different levels of cultural engagement (strong vs. weak). Based on the survey data collected in Poland in 2017, the analyses yield three main findings. First, cultural consumption continues to reflect social class divisions and is a potential mechanism for social exclusion. Second, network diversity is associated with cultural variety independently of class position. Third, the number of weak ties people hold is more strongly associated with the number of “weak” practices (that is practices of less frequency) and the number of strong ties is positively associated with the number of strong practices (voraciousness). These findings are discussed in terms of balance theory, interactional foci and weak versus strong culture. The implications of the article are that omnivorism both signifies class boundaries and indicates participation in different network structures.     

TO DETER OR TO MODERATE? ALLIANCE FORMATION IN CONTESTS WITH INCOMPLETE INFORMATION

We consider two players' choice about the formation of an alliance ahead of conflict in a framework with incomplete information about the strength of the potential ally. When deciding on alliance formation, players anticipate the self‐selection of other players and the informational value of own and other players' choices. In the absence of these signaling effects, strong players have an incentive to stand alone, which leads to a separating equilibrium. This separating equilibrium can be destabilized by deception incentives if beliefs are updated on the basis of endogenous alliance formation choices. Weak players may find it attractive to appear strong in order to deter competitors from positive effort choices. Strong players may find it attractive to appear weak in order to give their competitors a false sense of security and then beat them with little effort. Moreover, appearing weak allows players to free‐ride when alliances are formed. (JEL D72, D74)     

Nonresident Fathers' Contributions to Adolescent Well-Being

Using data from 453 adolescents in Wave 2 of the National Survey of Families and Households, we examine how multiple dimensions of nonresident father involvement are associated with different dimensions of child well-being. Father-child relationship quality and responsive fathering are modestly associated with fewer externalizing and internalizing problems among adolescents. The quality of the mother-child relationship, however, has stronger effects on child well-being. Nevertheless, even if adolescents have weak ties to mothers, those who have strong ties to nonresident fathers exhibit fewer internalizing problems and less acting out at school than adolescents who have weak ties to both parents. Adolescents are worst off on a range of outcomes when they have weak ties to both their mothers and nonresident fathers.     

Vision and state health department public relations practitioners: Prepared to lead?

Visions are important to organizational effectiveness. Although providing vision has been identified as one of the behaviors that best captures organization-wide public relations leadership, little public relations research has focused on vision. Similarly, state health departments have drawn little interest among public relations scholars even though states are a central part of the nation's public health system. This study addressed the perceptions of the top public relations professionals at state health departments concerning vision and their involvement in the visioning process. The practitioners were nearly unanimous in their belief that organizational visions are important. However, results indicate that some top public relations practitioners at state health departments are not prepared to make optimal contributions to the visioning process. In order to take full advantage of opportunities to serve as organization-wide leaders, public relations practitioners should seek out information about visioning in order help chart their organization's future and enhance their careers.     

Psychological predispositions and network structure: The relationship between individual predispositions,structural holes and network closure

We examine the effect of individual psychological differences on network structures, proposing several hypotheses about how individual differences might predispose actors to structure their social environment by seeking network closure or by sustaining structural holes. We introduce a new triad census method to examine personal networks of strong and weak ties. For 125 egocentric networks we correlated the triad census results with several extensively researched psychological instruments. The triad census reduced to three principal components, describing central aspects of strength-of-weak-ties and structural holes theories. Psychological predispositions explained a significant proportion of the variance in each of these components. Our results suggest that people who see themselves vulnerable to external forces tend to inhabit closed networks of weak connections. On the other hand, people who seek to keep their strong tie partners apart, and thereby bridge structural holes, tend to be individualists, to believe that they control the events in their lives, and to have higher levels of neuroticism. Finally, people with strong network closure and “weak” structural holes (as with the “strength of weak ties”) tend to categorize themselves and others in terms of group memberships. They also tend to be more extraverted and less individualistic.     

Unless you go online you are on your own: blogging as a bridge in para-sport

Since its inception, the Web has been described as a liberating technology permitting individuals with disabilities to surmount barriers that otherwise prevent full societal engagement. Subsequent studies of Web-based communication have instead reported that disabling conditions are reproduced rather than challenged online. This paper uses interviews with 25 para-sport participants to provide an empirical account of how the affordances of the Web are leveraged in disability sport networks. Our findings suggest that individuals with disabilities are using blogs, Facebook, Twitter, and other forms of online communication to find information, engage in advocacy and outreach projects, and form strong networks that extend online and offline. We discuss our findings in light of Putnam’s conceptualization of bridging and bonding social capital, and describe how individuals and groups use weak ties to disseminate information and strong ties to foster a sense of belonging.     

Gender homophily from spatial behavior in a primary school: A sociometric study

We investigate gender homophily in the spatial proximity of children (6–12 years old) in a French primary school, using time-resolved data on face-to-face proximity recorded by means of wearable sensors. For strong ties, i.e., for pairs of children who interact more than a defined threshold, we find statistical evidence of gender preference that increases with grade. For weak ties, conversely, gender homophily is negatively correlated with grade for girls, and positively correlated with grade for boys. This different evolution with grade of weak and strong ties exposes a contrasted picture of gender homophily.     

IS WORK THE NEW NEIGHBORHOOD? Social Ties in the Workplace,Family, and Neighborhood

The work–family literature emphasizes how work intrudes into family life, and some scholars suggest that social ties based in the workplace may be replacing ties to family or neighbors. Using data from the Ecology of Careers Panel Study, we describe the prevalence of strong ties with family, coworkers, and neighbors in a dual‐earner, middle‐class sample. We also examine which respondents are more likely to have strong ties in the workplace. We find that most respondents do not have any strong ties with coworkers; however, coworker ties are much more common than ties to neighbors. Additionally, there are gender differences in network ties and these differences may have important consequences for social support.     

Job-search Networks and Wage Attainment in China: A Comparison of Job Changers and Non-changers

This article examines job-search networks and entry-level wage attainment using data from a large-scale survey conducted in eight cities in China in 2009. Two key issues are addressed: (i) how the use of social networks is associated with entry-level wage attainment in urban China, and (ii) whether the patterns of network effects on entry-level wage differ between job changers and first-job seekers. The results show that both strength of ties and social resources of job-search networks are significantly associated with entry-level wage attainment, and that the network effects on entry-level wage are greater for job changers than for first-job seekers. This study offers a solid empirical verification of the associations of weak ties with information and strong ties with influence in an analysis of entry-level wages for job changers and first-job seekers.
