As the network technique is fast developing, the microblog has been a significant carrier representing the social public opinions. Therefore, it is important to investigate the propagation characteristics of the topics and to unearth the opinion leaders in Micro-blog network. The propagation status of the hot topics in the Micro-blog is influenced by the authority of the participating individuals. We build a time-varying model with the variational external field strength to simulate the topic propagation process. This model also fits for the multimodal events. The opinion leaders are important individuals who remarkably influence the topic discussions in its propagation process. They can help to guide the healthy development of public opinion. We build an AHP model based on the influence, the support, and the activity of a node, as well as a microblog-rank algorithm based on the weighted undirected network, to unearth and analyze the opinion leaders’ characteristics. The experiments in the data, collected from the Sina Micro-blog from October 2012 to November 2012 and from January 2013 to February 2013, show that our models predict the trend of hot topic efficiently and the opinion leaders we found are reasonable.

Evidence Based Programs

Evidence-based programs, such as bullying prevention, often demonstrate disappointing outcomes when widely disseminated. Engaging opinion leaders – those individuals whom others emulate and go to for advice – in the process of adaptation and implementation may improve outcomes. However, opinion leaders have the most influence on individuals who are similar to them, making social groups an important consideration in opinion leader recruitment. In a series of studies we examined the social groups of childhood and whether teacher nominations can be used to identify opinion leaders within these groups. In Study 1, students ( N = 35) and school staff members ( N = 23) reported on social groups at their school. Results suggest four predominant social groups (Elites, Athletes, Academic, and Deviants), and that students and adults are equally likely to identify these groups. In Study 2, students ( N = 29) and school staff members ( N = 10) identified opinion leaders from each of the four predominant social groups. Student and school staff members agreed on the primary opinion leader within the Elites, Athletes, and Academics groups, but identified different opinion leaders from the Deviants group. We conclude with relevance of these findings to schools and suggestions for further research.

A large amount of semantic content is generated during designer collaboration in open-source projects (OSPs). Based on the characteristics of knowledge collaboration behavior in OSPs, we constructed a directed, weighted, semantic-based knowledge collaborative network. Four social network analysis indexes were created to identify the key opinion leader nodes in the network using the entropy weight and TOPSIS method. Further, three degradation modes were designed for (1) the collaborative behavior of opinion leaders, (2) main knowledge dissemination behavior, and (3) main knowledge contribution behavior. Regarding the degradation model of the collaborative behavior of opinion leaders, we considered the propagation characteristics of opinion leaders to other nodes, and we created a susceptible–infected–removed (SIR) propagation model of the influence of opinion leaders’ behaviors. Finally, based on empirical data from the Local Motors open-source vehicle design community, a dynamic robustness analysis experiment was carried out. The results showed that the robustness of our constructed network varied for different degradation modes: the degradation of the opinion leaders’ collaborative behavior had the lowest robustness; this was followed by the main knowledge dissemination behavior and the main knowledge contribution behavior; the degradation of random behavior had the highest robustness. Our method revealed the influence of the degradation of collaborative behavior of different types of nodes on the robustness of the network. This could be used to formulate the management strategy of the open-source design community, thus promoting the stable development of OSPs.

ABSTRACT: This study aims to analyze the social networks of women workers in the KASBI Labor Union. The union was founded in 2005 to fight for women workers who work in the PT. Tirta Mahakam Resources Tbk. In a factory that is predominantly women, the need for a union is a must as a means of protection. For this reason, the existence of the Union is very dependent on the struggle of women in it. From the observations, it can be identified that six actors are the centers of information for women labor union members. Divided into categories of stars (Star) and opinion leaders (Opinion Leader) and recruitment. From the observations, six actors have the most extensive social networks among other individuals. The six actors also have different interaction models, this is a potential asset for both the actor and the Union. There are three networks in it, namely interest networking (interests), sentiment networking (emotional network), and power networking (power network). The typology of social capital of the Union is also to bridge the bridging of social capital, which is that it leads to the search for joint answers to solve problems faced by the group and is open to other unions. ABSTRAK: Penelitian ini bertujuan menganalisis jaringan sosial buruh perempuan di dalam Serikat Buruh KASBI. Serikat yang berdiri pada tahun 2005 dalam upaya perjuangan buruh perempuan yang bekerja di dalam pabrik PT. Tirta Mahakam Resources Tbk. didalam pabrik yang mayoritas perempuan, Kebutuhan akan adanya Serikat merupakan keharusan sebagai sebuah wadah perlindungan. Untuk itu eksistensi Serikat sangat tergantung pada perjuangan perempuan di dalamnya. Dari hasil pengamatan dapat diidentifikasi terdapat enam aktor yang menjadi pusat informasi bagi anggota Serikat Buruh perempuan.  Terbagi menjadi kategori bintang (Star) dan pemimpin opini (Opinion Leader) dan rekrutmen. Dari hasil pengamatan, terdapat enam aktor memiliki jaringan sosial yang paling luas diantara indivisu-individu lainya. Keenam aktor juga memiliki model interaksi yang berbeda-beda, hal tersebut merupkan modal yang potensial bagi aktor maupun Serikat. Terdapat tiga jaringan di dalamnya yaitu jaringan interest networking (kepentingan), sentiment networking (jaringan emosi), dan power networking (jaringan kekuasaan). Tipologi modal sosial Serikatpun bersifat menjembatani bridging social capital yaitu yang mengarah kepada pencarian jawaban bersama untuk menyelesaikan masalah yang dihadapi oleh kelompok serta terbuka kepada Serikat lain.

Bounded Confidence Model

Seeking truth is an important objective of agents in social groups. Opinion leaders in social groups may help or hinder the other agents on seeking the truth by symmetric nature. This paper studies the impact of opinion leaders by considering four characteristics of opinion leaders—reputation, stubbornness, appeal, and extremeness—on the truth-seeking behavior of agents based on a bounded confidence model. Simulations show that increasing the appeal of the leader whose opinion is opposite to the truth has a straightforward impact, i.e., it normally prevents the agents from finding the truth. On the other hand, it also makes the agents who start out close to the truth move away from the truth by increasing the group bound of confidence, if there is an opinion leader opposite to the truth. The results demonstrate that the opinion of the leader is important in affecting the normal agents to reach the truth. Furthermore, for some cases, small variations of the parameters defining the agents’ characteristics can lead to large scale changes in the social group.

Purpose This study aims to identify how the personal social capital of opinion leaders contributes to the market adoption of start-up innovations. Design/methodology/approach A design-oriented case study is undertaken with a start-up company focusing on the development and commercialization of innovations in the veterinary market. Based on a literature review, the authors examine the social capital in value creation and the role of opinion leaders and use qualitative methodology and semi-structured in-depth interviews to collect data. Findings The adoption of innovations could start with opinion leaders that will later share their experience with other members of the professional community. In turn, social capital allows for creating a collaboration between start-ups and leaders based on a number of specific parameters. Originality/value This paper contributes to marketing literature by providing new insights regarding collaboration between start-ups and opinion leaders. The collaboration between opinion leaders and start-ups could be implemented not only in the veterinary industry but also in other industries with minor adaptations. Authors demonstrate how the social capital of external stakeholders may be used as a resource of the company for business development. The main contribution of this study is to demonstrate that social capital could be used as a parameter for the adoption of innovations. The key parameters that allow creating cooperation between start-up and opinion leader have been identified.

This study examined the individual and collective influence of conspiracy theories, misinformation and knowledge revolving around COVID-19, on public adoption of the Nigerian government’s containment policies. The study adopted the Survey, and Focus Group Discussion (FGD) methods. For the survey, a sample of 466 respondents were drawn from Facebook, Instagram, Messenger and WhatsApp, while 24 participants were selected for the FGD. The Statistical Package for Social Sciences (SPSS) and thematic approach were used to analyse data generated from the study. Results revealed a COVID-19 conspiratorial thinking among survey respondents and FGD participants, who were also familiar with the orgy of unbridled dissemination of misinformation and conspiracy theories in the social media space. Majority of respondents were knowledgeable about government’s COVID-19 containment policies and were practicing the recommended safety measures. Their decision was influenced by trust in opinion leaders, especially family members and medical experts.

To remember or forget our acquaintances’ strategies can influence our decision-making significantly. In this paper, we explore the evolutionary prisoner’s dilemma (PD) game model with punishment and memory mechanism in the time-varying network. Our results show that a larger temptation gain [Formula: see text] or a larger the number of connected edges of activated individuals [Formula: see text] would result in the decrease of the final fraction of cooperators. However, with the increase of the maximum penalty cost, the maximum punishment intensity or the value of individual’s “memory factor”, players are more inclined to choose cooperative strategy. In addition, an effective way to promote the cooperation is to improve the social subsidy. Remarkably, only when the social subsidy is greater than the temptation gain, the density of cooperators could increase significantly. Interestingly, there is a linear relationship between the threshold of social subsidy and the temptation gain. The final results show that ones’ activity rates have no significant correlation with their strategies.

The Public

Health opinion leaders have widely embraced social media for health promotion and public health communication which can make a strong influence on the public decision making. However, despite the growing relevance of public health threats such as infectious diseases, pandemic influenza and natural disasters, research has paid little attention to the qualities of opinion leaders. Moreover, there is limited evidence that public health organisations use social media appropriately to engage in meaningful conversations with audiences. Thus, the aims of the study are to describe principles of communication practised by online opinion leaders to promote health issues, to discuss the strategies of social media used, to explain the opinion leaders’ influence attributes in health decision making and finally to develop a model of online opinion leader in the contemporary health promotion era. Content analysis was conducted on Facebook postings of five selected health opinion leaders. In addition, semi-structured interviews with 10 followers were conducted. The findings of the study revealed that there are three principles of communication practised by online opinion leaders, which are language, interaction and themes. There are three strategies opinion leaders use to influence the public: social connectivity, social support and social consultation. Furthermore, there are five opinion leaders’ attributes that influence the public’s decision making, namely personality, authenticity, trust/credibility, professional knowledge and social position. The model would be beneficial in educating and guiding the current public health opinion leaders in order to establish health and social well-being. Keywords: Online opinion leader, online health communication, public health, two-step flow theory, decision making.
