This paper analyzes the role of propaganda use in cyberterrorism. The main premise is that cyberterrorists display various semiotic gestures (e.g., the use of images and Internet videos) to communicate their intents to the public at large. In doing so, they communicate themes??these themes range from hate to anger. Cyberterrorism, then, is a form of theater or spectacle in which terrorists exploit cyberspace to trigger feelings of panic and overreaction in the target population. In many cases, this form of propaganda is the primary means of communication for various cyberterrorist groups to convey their intents. Internet sites also produce numerous opportunities for in-group communication and publicity.  相似文献

This study examined how ethnic identity relates to large-scale brain networks implicated in social interactions, social cognition, self-definition, and cognitive control. Group Iterative Multiple Model Estimation (GIMME) was used to create sparse, person-specific networks among the default mode and frontoparietal resting-state networks in a diverse sample of 104 youths aged 17–21. Links between neural density (i.e., number of connections within and between these networks) and ethnic identity exploration and resolution were evaluated in the full sample. Ethnic identity resolution was positively related to frontoparietal network density, suggesting that having clarity about one’s ethnic group membership is associated with brain network organization reflecting cognitive control. These findings help fill a critical knowledge gap about the neural underpinnings of ethnic identity.  相似文献

Community informatics provides new ways of approaching old problems of community development and enhancing civic society. Building on a theoretical analysis, this article discusses research in the area of the efforts of community networks in the USA to achieve outcomes in these two areas using the tools of community telecommunications and networking. The analysis matches the theoretical arguments for how community building and civic society are achieved against the practice of community networks trying to implement the new communications technologies. The analysis shows that achieving these goals is difficult for community information networks and that a full understanding of the nature of community information infrastructures could likely be very helpful in this task.  相似文献

The burgeoning study of social support in relation to social stress and health would benefit from increased attention to issues of social structure. Three aspects of social relationships, all often referred to as social support, must be more clearly distinguished—(1) their existence or quantity (i.e., social integration), (2) their formal structure (i.e., social networks), and (3) their functional or behavioral content (i.e., the most precise meaning of social support)—and the causal relationships between the structure of social relationships (social integration and networks) and their functional content (social support) must be more clearly understood. Research and theory are needed on the determinants of social integration, networks, and support as well as their consequences for stress and health. Among potential determinants, macrosocial structures and processes particularly merit attention.  相似文献

Inventions – concepts, devices, procedures – are often created by networks of interacting agents in which the agents can be individuals (as in a scientific discipline) or they can themselves be collectives (as in firms interacting in a market). Different collectives create and invent at different rates. It is plausible that the rate of invention is jointly determined by properties of the agents (e.g., their cognitive capacity) and by properties of the network of interactions (e.g., the density of the communication links), but little is known about such two-level interactions. We present an agent-based model of social creativity in which the individual agent captures key features of the human cognitive architecture derived from cognitive psychology, and the interactions are modeled by agents exchanging partial results of their symbolic processing of task information. We investigated the effect of agent and network properties on rates of invention and diffusion in the network via systematic parameter variations. Simulation runs show, among other results, that (a) the simulation exhibits network effects, i.e., the model captures the beneficial effect of collaboration; (b) the density of connections produces diminishing returns in term of the benefits on the invention rate; and (c) limits on the cognitive capacity of the individual agents have the counterintuitive consequence of focusing their efforts. Limitations and relations to other computer simulation models of creative collectives are discussed.  相似文献

This article explores the impact of the Internet and related technologies on the nature of deviant behavior, deviant communities, and the future of deviance research. The idea that pathological communities, once largely suppressed by time, space, and societal restraints, can now create and use virtual communities is focal. Those new communities may expand their numbers and/or pathology, while reinforcing their rationales for rule violations. Investigation of these new virtual communities is especially complex for both conceptual and methodological reasons: identity is hard to ascertain in cyber-settings; nationality, ethnicity and other background traits and standard (e.g., random) sampling methods are not feasible. Nonetheless, the impact of communications technology on the creation and expansion of pathologically deviant communities requires exploration to determine whether, for example, immersion and social support lead to satiation-catharsis, more aggressive real-time behavior, and/or increases in the depth and number of pathological sexual preferences.  相似文献

This paper investigates a linkage between micro- and macrostructures as an intrinsic property of social networks. In particular, it examines the linkage between equicentrality [Kang, S.M., 2007. A note on measures of similarity based on centrality. Social Networks 29, 137–142] as a conceptualization of a microstructural process (i.e., the likelihood of social actors to be connected with similarly central others) and network centralization as a macrostructural construct, and shows that they have a negative linear association. In other words, when actors are connected with similarly central alters (i.e., high equicentrality), the overall network centralization is low. Conversely, when highly central actors are connected with low-centrality actors (i.e., low equicentrality), the overall network centralization is high. The relationship between degree equicentrality and degree centralization is more significant in observed networks, especially those evolving over time, as compared to random networks. An application of this property is given by venture capital co-investment networks.  相似文献

The Internet offers adolescents unique opportunities to actively shape their own sexual media environment. The aim of this study was to gain in-depth insight into Dutch adolescents’ motives, perceptions, and reflections toward Internet use for (a) finding information or advice related to romance and sexuality; (b) searching for and viewing pornographic or erotic material; and (c) romantic and sexual communication (i.e., cybersex/sexting). Data were collected through 12 Web-based focus groups (36 adolescents aged 16 to 19 years, 72.2% girls) and analyzed through three stages of open, axial, and selective coding. The themes that emerged from the focus-group discussions suggest that sex-related Internet use is a complex and ambivalent experience for adolescents. Sex-related Internet use seems an increasingly normalized and common phenomenon. Participants perceived the Internet as a useful source of sexual information, stimulation, inspiration, and communication. Yet they discussed a range of negative consequences and risks related to sex-related online behaviors, particularly concerning pornography’s potential to create unrealistic expectations about sex and sexual attractiveness. Participants generally believed they had the necessary skills to navigate through the online sexual landscape in a responsible way, although they believed other young people could be influenced inadvertently and adversely by sex-related online content.  相似文献

This study examines when and why employees engage in external communicative behaviors during the periods of a corporate crisis. Combining a cross-situational factor (i.e., pre-crisis relationship quality) and a situational factor (i.e., crisis-specific perceptions), this study segments internal publics to understand employees’ motivations of becoming advocates for or adversaries of their organization. The results of an online survey demonstrated that employees’ pre-crisis relationship to their organization plays a critical role in encouraging them to advocate for their company; meanwhile, their crisis-perception—whether they feel fewer constraints in solving a crisis—is more likely to make them share negative information externally. Segmented groups of employees with high levels of both relationship and activeness are most likely to engage in both positive and negative external communication behaviors. Theoretical and practical implications for public relations and internal crisis communication are suggested.  相似文献

This article reviews the literature on gay and lesbian family networks as a way to identify the resilience processes that enable members to create and strengthen their family networks. Two processes, intentionality and redefinition, were identified. Intentionality refers to behavioral strategies that legitimize and support relationships. Redefinition refers to meaning making strategies that create linguistic and symbolic structures to affirm one's network. Brief comparisons are made to the literature on resilience in ethnic minority families, and careful study of the similarities and differences between gay and lesbian family networks, and other marginalized families, is urged.  相似文献

Debate on the social role of the Internet has centred on whether its use will tend to isolate or connect individuals, undermining or reinforcing social ties. This study moves away from this focus on more or less connectivity to explore the degree to which people use the Internet to make new friends and, thereby, reconfigure their social networks. The analysis identifies those who create new ties through the Internet and investigates under what conditions these online ties migrate to face to face settings. The analysis is based on data from the 2005 Oxford Internet Survey (OxIS), a national probability sample survey of individuals aged 14 and over in Britain. The findings indicate that about 20 per cent of Internet users have met new friends online, and about half of these individuals go on to meet one or more of these virtual friends in person. Sociodemographic characteristics, such as being single, shape patterns of Internet use, and are related to the greater propensity of some individuals to make online social relationships. However, experience with the Internet and the ways people choose to use the Internet, such as for chatting or communicating more generally, are most directly associated with who makes new connections over the Internet and who does not. These findings suggest that the Internet plays an important role in reconfiguring the social networks of many users. Also, multivariate analyses indicate that the dynamics of online friendships are driven more by the idiosyncratic digital choices made by users of the Internet than by any mechanistic social or technological determinism.  相似文献

Although the amount of research on interorganizational networks has increased significantly in recent years, few studies have examined the antecedents to interorganizational network portfolios—organizations’ configuration of their relationship networks with other organizations. To address this gap, this study examines how firms’ interorganizational network portfolios vary across three types of ownership structures (i.e., state-owned, private, and multinational enterprises) in China. Cluster analysis of the data on 212 leading firms operating in China revealed two types of network portfolios firms maintain. Specifically, firms maintaining robust cross-sector portfolios had more extensive networks with organizations in the nonprofit and public sectors than firms maintaining limited cross-sector portfolios. Moreover, regression results suggested that firms across different ownership structures had distinct numbers and types of organizational partners, particularly nongovernmental organization (NGO) partners. Theoretical and practical implications are derived from the findings.  相似文献

Individualism is a frequently referenced but seldom inspected topic within urban poverty literature. Residents of low‐income communities may internalize their social immobility by perceiving status to be determined by choices, behaviors, and psychological or moral shortcomings, but scholars generally depict such individualistic outlooks as only a byproduct of more predominant community dysfunctions. As a result, individualism—an ambiguous and confounding concept at all social strata—can assume an especially disapproving tenor when applied to the urban poor, often connoting qualities of defensiveness, ignorance, and quixotic hope. In this article, I draw from ethnographic fieldwork in Houston's Fifth Ward community to explore individualism's meanings and utility within a context of compromised prospects for positive self‐determination. I explain how defensiveness against vulnerability, violence, and volatile relationships is just one rationale for individualism that is exercised alongside other, still structurally framed rationales (i.e., expressive and meritocratic) on the viability of social mobility.  相似文献

In two studies we investigate whether social exclusion—a well-studied, common and quite painful social experience-influences people's perceptions of novel social networks. In a first study, exclusion experiences led people to report that novel networks were more dense relative to those who had not been excluded. As predicted, this was true only for social networks; exclusion had no impact on perceptions when networks were described as geographical. In a follow-up experiment, participants watched a custom-created video, depicting avatars interacting in social scenes and they were asked to report the ties among the avatars in the video. Exclusion experiences led people to see network ties where none exist (i.e., false positives), though there was no effect for exclusion (versus inclusion) on reports of false negatives. Results indicate that common social experiences systematically shape network perceptions, leading people to seeing novel social networks as more densely connected than they are.  相似文献

This study explores negative posts in Facebook pages dedicated to dead subjects. As with places for mourning in offline environments, memorial pages in Facebook appear to exude a sacred character as objects to both celebrate the life of the deceased and grieve their departure with others. Through a two-step content analysis of an initial sample of 600 pages containing the ‘R.I.P.’ acronym in their title, we found, however, a number of posts violating conventional expectations of respect for these mourning spaces. Negative posts in memorial pages take the form of flames (i.e., insults directed at the subject of the page, its administrator, or other visitors), venting (e.g., violent language against the victimizers of the subject of a memorial page), or ‘spam’ (i.e., advertisement and content not related to the subject and purpose of the page). Moreover, while results show that most memorial pages in Facebook are created and maintained by women (even thought the subject in the majority of those pages are young males who died an untimely death), they also reveal that women post the majority of negative posts in those pages as well. In other words, whereas women seem to perpetuate traditional offline roles in connection to mourning and grieving rituals, in the online world, they are also the first ones challenging the socially sanctioned sacral attributes of those practices in social networking sites.  相似文献

As the Internet becomes pervasive in western societies, social capital emerges as a valuable sociological tool to analyze the social effects of Internet use. Thus, a growing body of research has been looking into the relationship between social capital and Internet usage. This research has been showing a positive relationship between them; however, results are not as conclusive when we consider one of the main dimensions of social capital: bonding. Bonding relates to resources that are embedded in one’s strong ties (i.e., family members and close friends). The study of bonding is of particular sociological interest, since the discussion around the social effects of the Internet still suggests that it takes time away from strong ties and that is more useful to connect with weak ties (i.e., acquaintances). This study examines the relationship between bonding and the Internet, using representative survey data and semi-structured interviews from Portugal. Findings show that bonding is predicted positively by Internet use but negatively by age. On one hand, the Internet seems to compensate for the negative age effect because older adults who use it are more likely to have a high level of bonding. On the other hand, the Internet reinforces accumulated social advantage.  相似文献

The recent development of networks has engendered both the evanescence of “macro-actors” (i.e., big formal organizations) and new problems related to corporate social responsibility. The concept of “organization” must be redefined and analyzed so as to identify network externalities and the ways (including legal ones) of handling the consequences in terms of liability. The four brief contributions in this section — two by sociologists and two by jurists — outline an approach to the contemporary reality of organizations.  相似文献

Drawing from 2 largely isolated approaches to the study of social stress—stress proliferation and minority stress—the authors theorize about stress and mental health among same‐sex couples. With this integrated stress framework, they hypothesized that couple‐level minority stressors may be experienced by individual partners and jointly by couples as a result of the stigmatized status of their same‐sex relationship—a novel concept. They also consider dyadic minority stress processes, which result from the relational experience of individual‐level minority stressors between partners. Because this framework includes stressors emanating from both status‐based (e.g., sexual minority) and role‐based (e.g., partner) stress domains, it facilitates the study of stress proliferation linking minority stress (e.g., discrimination), more commonly experienced relational stress (e.g., conflict), and mental health. This framework can be applied to the study of stress and health among other marginalized couples, such as interracial/ethnic, interfaith, and age‐discrepant couples.  相似文献

The New Normal1     
The Great Recession has caused many Americans to reevaluate their consumption‐rich way of life. In response to the shrinking economy, they have spent less, saved more, and simplified their lives. This essay asks whether people will seek a return to their prerecession lifestyles—in particular a return to making the acquisition and consumption of consumer goods a major source of meaning and contentment—as soon as their economic condition allows or whether they will make their more austere lives their “new normal.” It evaluates existing research on contentment and suggests that if instead of choosing to return to their “old normal,” Americans learn to derive satisfaction from nonconsumerist sources, in particular social relations and transcendental activities (i.e., religious, contemplative, and cultural activities), they may find the new normal quite acceptable.  相似文献

As a consequence of the lockdown measures imposed by the Belgian government to fight against COVID‐19, migrant live‐in elderly carers had to choose between safeguarding their job — at the detriment of their personal freedom, their health and their working conditions — and safeguarding their freedom but losing their job — at the detriment of their economic survival and that of their families. This article explores this dilemma from an intersectionality perspective. In order to understand their experience in times of COVID‐19 and their response to this dilemma, I analyse their position as women, as migrants, as elderly care workers, as family breadwinners and as ‘quasi‐family members’ in the families of their employer — which correspond to five interlocking systems of oppression.  相似文献
