This paper studies social network changes during the COVID-19 crisis in the Netherlands and their relation to perceived loneliness for the younger and the older cohorts. Arguments from opportunity theory and social capital theory are used to formulate hypotheses on network changes during the pandemic. Core discussion networks and networks with practical helpers from two representative cohorts (18–35 years of age and 65+ years of age, n = 1342 participants in both waves) during the lockdown in May 2020 are compared with networks of the same respondents in May 2019. We find that networks became smaller and more focused on stronger ties, while weaker ties more often decayed. Feelings of loneliness incsreased on average for all respondents and in particular for those who live alone or have a disadvantaged socioeconomic position. Importantly, the decrease in the number of the practical helper network, that is, decline in relatively weaker ties, affects experiences of loneliness in both groups.  相似文献

Health status may shape network structure through network dynamics (tie formation and persistence) and direction (sent and received ties), net of typical network processes. We apply Separable Temporal Exponential Random Graph Models (STERGMs) to National Longitudinal Study of Adolescent to Adult Health survey data (n = 1779) to differentiate how health status shapes network sent and received tie formation and persistence. Results indicate that networks are shaped by withdrawal of adolescents experiencing poor health, highlighting the importance of separating distinct and directed processes of friendship formation and persistence when considering how health relates to adolescent social life.  相似文献

Coparenting can be a development-enhancing or risk-promoting environment for infant regulatory capacity, mainly in the presence of adversity. This study aimed to analyze the association between positive and negative coparenting previous to the COVID-19 pandemic and infant regulatory capacity in the presence of the COVID-19 pandemic, an adverse condition. A sample of 71 first-born infants and their mothers and fathers from a longitudinal cohort in Portugal were assessed at 2 weeks postpartum before the COVID-19 pandemic and again at 6 months postpartum, before (n = 35) or during the COVID-19 pandemic (n = 36). Parents completed measures of positive and negative coparenting and infant regulatory capacity in both assessment waves. Results revealed that the presence of the COVID-19 pandemic moderates the association between mothers' and fathers' positive coparenting previous to the COVID-19 pandemic and infant regulatory capacity at 6 months. The association between positive coparenting and regulatory capacity was stronger in infants facing the COVID-19 pandemic, than in infants who did not face the COVID-19 pandemic. Positive coparenting previous to the COVID-19 pandemic may be a development-enhancing environment for infant regulatory capacity in the presence of the COVID-19 pandemic. Positive coparenting may buffer regulatory problems in infants facing adverse conditions.  相似文献

This paper examines linguistic variation on an Internet Relay Chat channel with respect to the hypothesis, based on the model of Milroy and Milroy (1992), that standard variants tend to be associated with weak social network ties, while vernacular variants are associated with strong network ties. An analysis of frequency of contact as a measure of tie strength reveals a structured relationship between tie strength and several linguistic variants. However, the variant features are associated with social positions in a way that does not correlate neatly with tie strength. An account of these results is proposed in terms of the social functions of the different variables and the larger social context of IRC affecting tie strength.  相似文献

The COVID-19 pandemic may impact the development of infants' social communication patterns with their caregivers. The current study examined continuity, stability, and bidirectional associations in maternal and infant dyadic Emotional Availability (EA) before and during the COVID-19 pandemic. Participants were 110 Israeli mother-infant dyads (51% girls) that were assessed prior to (Mage = 3.5 months) and during (Mage = 12.4 months) the pandemic. At both time points, mother-infant interactions were observed during play (nonstressful context) and tasks designed to elicit infant frustration (stressful context). Maternal and child EA were coded offline. Maternal EA demonstrated no significant mean-level changes from before to during the COVID-19 pandemic, whereas infant responsiveness and involvement increased over time. Stability and bidirectional associations in EA differed by context and were evident only in the stressful context. Mothers' perceived levels of social support further moderated these associations. Specifically, infants' pre-pandemic responsiveness and involvement predicted maternal EA during the pandemic only when mothers reported low levels of social support. Our findings suggest that maternal and child EA were not adversely impacted by the COVID-19 pandemic. However, patterns of EA demonstrated moderate-to-no stability over time, suggesting considerable individual differences in trajectories of EA.  相似文献

This article asks how return migration intentions are shaped by ties to the country of residence on the one hand, and ties to the country of origin on the other. We discuss these two sets of ties in terms of immigrant integration and transnationalism, respectively. A central tenet of the study is that, at the individual level, integration and transnationalism are neither related in a predictable way nor independent of each other. In our analysis we take methodological steps that reflect this argument, and introduce an integration–transnationalism matrix. In the empirical analysis we use quantitative survey data (N = 3,053) on ten large immigrant groups in Norway, collected by Statistics Norway in 2005–06. We find that it is the relative strength of integration and transnationalism that is decisive for return migration intentions.  相似文献

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.  相似文献

Given increased political polarization and racial tension in the wake of the 2016 presidential election in the United States, this study examines dropped ties in personal networks at that time based on political and racial identities. We employed data from the 2015–2018 UCNets study (n = 1159), a longitudinal, representative data set of the San Francisco Bay Area. In late 2015 and early 2016 it generated personal network data via multiple name generators, eliciting alters whom respondents socialized with, confided in, received advice from, exchanged social support with, and found difficult. Using multilevel multinomial logit models, we then examined various reasons for tie dissolution immediately following the inauguration of Trump in early 2017. The results show that among young adults, politically dissimilar alters were more likely to be dropped due to disagreements. With respect to racial homophily, we found that interracial dyads were more likely to be dropped because of drifting apart or some other reason for both younger and older cohorts. Overall, there is some support for the notion that dropped ties due to political disagreements did occur immediately following the 2016 election, but the results highlight the continuing significance of race in personal networks.  相似文献

This paper addresses the question “To what extent can job satisfaction be explained as the revenue of social capital?” By conceiving someone’s social network as social capital we specify conditions under which social ties do lead to job satisfaction. We inquire into the idea of goal specificity of social capital, which implies that a network with a given structure and content will have different impacts on various aspects of job satisfaction. If the content of the ties and the structure of the network at the job engender material well-being or produce social approval, satisfaction with the corresponding job aspects increases. Data were collected in 1993 using written questionnaires in two Dutch governmental agencies, one with 32 and the other with 44 employees. These workers’ networks were charted using nine name-generating questions.Social capital, it turns out, is not an all-purpose good but one that is goal specific, even within a single domain of life such as work. Three effects stand out: First, the structure of the network and the content of the ties do matter. Networks of strategic, work-related ties promote an employee’s satisfaction with instrumental aspects of the job, like income, security, and career opportunities. Second, closed networks of identity-based solidarity ties improve an employee’s satisfaction with social aspects of the job, like the general social climate at work and cooperation with management and colleagues. Third, a network with a bow–tie structure (i.e., where a focal actor is the link between two or more mutually exclusive cliques) generally has strong negative effects on satisfaction with the social side of the job; although a bow–tie type network of trusting ties does increase satisfaction with the social side. This implies that Krackhardt’s hypothesis on the unpleasant feelings produced by bow–tie type networks has to be specified for the content of the ties that constitute such a network. The most important conclusion of our analysis is that goal specificity of social capital has implications for both structure and content of social networks. Achievement of a particular goal, such as satisfaction at work, requires not only networks of a certain structure or ties with a particular content, but specifically structured networks of ties with a particular content.  相似文献

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.  相似文献

The relationship between network structure and access to novel information has fascinated social scientists for decades, culminating in the recent identification of the bandwidth-diversity tradeoff. Yet, existing work focuses on a unidimensional conception of network ties that leaves many important sources of novel information unexplored. We unpack bandwidth, identifying three factors that govern the transmission behavior of network ties: capacity (the ability of a tie to transmit content), frequency (the average time between tie activations), and redundancy (the extent to which a tie reaches persons who are connected to each other). Empirical analyses and simulation models reveal new types of ties, as well as the conventional variety, that open promising research avenues.  相似文献

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.  相似文献

Previous research finds that individuals tend to form ties with similar others much more often than with dissimilar others. However, we know relatively little about tie loss and to what extent this is driven by (dis)similarity. In this paper, we argue that ties to persons who are dissimilar with regard to gender, age, ethnicity, and education are lost faster than ties to similar persons – and we test three explanations for this faster decay of ties with dissimilar others: lack of meeting opportunities, preferences for similarity, and lower network embeddedness. To test these explanations, we analysed two waves of the Survey on the Social Networks of the Dutch (SSND, 2007, 2014). These SSND-waves contain comprehensive longitudinal panel data on ego networks of 441 respondents, who were interviewed about a wide range of relationships, their alters’ sociodemographic characteristics, where and when they met their alters, as well as how and whether they maintain these relationships. We modelled tie loss by event history analyses. Results show that ties to persons who were dissimilar are more likely to be lost faster, and that tie loss occurs mostly in the early years of a relationship. However, meeting opportunities, preferences for similarity, and network embeddedness are unable to explain why ties to dissimilar others are lost faster. We conclude that dissimilarity is a powerful driver of tie loss, and that more arguments and research are needed to fully understand the underlying mechanisms.  相似文献

We examine the affective content of ties and explore whether negative affective tie content is systematically advantaged or disadvantaged when recalling the social network as compared to positive affective tie content. We test this in three workgroups from two organizations and analyze differences in perceptual accuracy comparing negative and positive affective tie perception. We theorize that ego will be more accurate for others’ positive than negative ties due to generalized positivity bias, or the Pollyanna principle. We also theorize that ego will be more accurate for their own negative ties due to negative asymmetry perspective, as ego will attend more to those ties that pose a personal threat. Findings suggest that observers were more accurate overall about their own and others’ positive compared to negative affective ties. We conclude that the Pollyanna principle is an important factor in explaining perceptions in naturalistic cognitive networks. Supplementary analysis showed that negative ties were more likely to be missed and imagined and having a valenced tie toward another person influences perceptions of that persons’ network ties. Finally, we find that balanced and imbalanced triads were also important factors of relative accuracy. The study’s contribution, limitations, and future research are also discussed.  相似文献

Prominent hypotheses on the structure of African ape social organization are examined from a network perspective. Data on chimpanzee and gorilla social ties are summarized and assessed with respect to the hypotheses. Contrary to most of the literature on African apes, a network analysis of social ties reveals that chimpanzees and gorillas have similar structural arrangements in their respective patterns of social organization. Granovetter's weak tie mode of integration of a population at the macro level is used to explain the data.  相似文献

Urban sociologists and criminologists have long been interested in the link between neighborhood isolation and crime. Yet studies have focused predominantly on the internal dimension of social isolation (i.e., increased social disorganization and insufficient jobs and opportunities). This study highlights the need to assess the external dimension of neighborhood isolation, the disconnectedness from other neighborhoods in the city. Analyses of Chicago's neighborhood commuting network over twelve years (2002–2013) showed that violence predicted network isolation. Moreover, pairwise similarity in neighborhood violence predicted commuting ties, supporting homophily expectations. Violence homophily affected tie formation most, while neighborhood violence was important in dissolving ties.  相似文献

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.  相似文献

This study investigates how different aspects of social identity correlated with online networking and job search success. Undergraduates and recent graduates seeking public relations roles between 2020 and 2021 were surveyed (N = 355) for their early career job-seeking practices. The pre-existing lack of diversity in PR and the tendency to favor job candidates who are similar to the decision-maker means that the move to virtual relationship building and vetting may be especially impactful for diverse applicants. The results showed that networking was extremely important as over 94% of respondents found their position via networking of some sort. Respondents found roles most commonly via LinkedIn (57.5%), followed by other social media (49.9%). LinkedIn network size was positively correlated with more job offers, whereas Twitter and Facebook network sizes were insignificant. Those who identified as white used LinkedIn more and had more job offers than those who identified as BIPOC. Veterans and those receiving need-based assistance also reported having fewer job offers. This paper extends the strength of weak ties theory by demonstrating the importance of weak ties in digital networking in the PR industry. This research suggests that maintaining weak ties via LinkedIn is valuable for success in digital networking, particularly by growing a robust LinkedIn network and maintaining an active profile. Practical advice for PR educators and students illustrates how to enhance LinkedIn use to promote equity in digital networking. Moreover, the PR field may promote diversity among applicants and hires through mentoring, recruiting, and growing their own diverse digital network.  相似文献

This article investigates the effect of the Boston Marathon Bombing on city residents— how the tragic incident changed, or did not change, how Bostonians live in and feel about their community and neighborhoods. Unlike prior research that began weeks or months after a terrorist attack and used retrospective reports, this study spans the focal event. An address‐based sample of residents from three neighborhoods, distinct in racial and economic makeup was surveyed by mail using a three‐contact protocol. About two‐thirds of respondents answered a survey of neighborhood sentiments, and health and well‐being in the days before the bombing (N = 581) and slightly over a third answered the survey after the bombing (N = 313). Assessments of safety, city and neighborhood satisfaction and solidarity, mental health, and other key measures vary greatly between the three neighborhoods, which are diverse in racial and economic composition, but also vary in proximity to the bomb site. Net of neighborhood differences, the bombing had a strong negative effect on neighborhood cohesion and reduced use of public transit. Strong interactions are also found between timing of survey completion (pre and post bombing) and neighborhood for assessments of neighborhood solidarity.  相似文献
