Information dissemination groups, especially those disseminating the same kind of information such as advertising, product promotion, etc., compete with each other when their information spread on social networks. Most of the existing methods analyze the dissemination mechanism mainly upon the information itself without considering human characteristics, e.g. relation networks, cooperation/defection, etc. In this paper, we introduce a framework of social evolutionary game (SEG) to investigate the influence of human behaviors in competitive information dissemination. Coordination game is applied to represent human behaviors in the competition of asynchronous information diffusion. We perform a series of simulations through a specific game model to analyze the mechanism and factors of information diffusion, and show that when the benefits of competitive information is around 1.2 times of the original one, it can compensate the loss of reputation caused by the change of strategy. Furthermore, through experiments on a dataset of two films on Sina Weibo, we described the mechanism of competition evolution over real data of social network, and validated the effectiveness of our model.

The modern media ecology has changed drastically over the last decade yet scholarly theoretical perspectives lag behind lay theories regarding news diffusion making it difficult to fully articulate and understand the processes driving dissemination of information and persuasion across networks and media contexts. The proposed theoretical framework takes into account extant research on the multiple mechanisms, specifically, cognitive ego involvement, the media environment, and interpersonal processes that operate in concert to influence the way information about societal issues is diffused through digital communication channels. The theoretical framework of mediated skewed diffusion of issues information provides 11 testable propositions. These are put forth to provide a foundation and encourage future research on information dissemination, online persuasion, and position polarization.

Full textAbstract:
Information dissemination has become one of the most important services of communication networks. Modeling the diffusion of information through such networks is crucial for our modern information societies. In this work, novel models, segregating between useful and malicious types of information, are introduced, in order to better study Information Dissemination Dynamics (IDD) in wireless complex communication networks, and eventually allow taking into account special network features in IDD. According to the proposed models, and inspired from epidemiology, we investigate the IDD in various complex network types through the use of the Susceptible-Infected (SI) paradigm for useful information dissemination and the Susceptible-Infected-Susceptible (SIS) paradigm for malicious information spreading. We provide analysis and simulation results for both types of diffused information, in order to identify performance and robustness potentials for each dissemination process with respect to the characteristics of the underlying complex networking infrastructures. We demonstrate that the proposed approach can generically characterize IDD in wireless complex networks and reveal salient features of dissemination dynamics in each network type, which could eventually aid in the design of more advanced, robust, and efficient networks and services.

Full textAbstract:
The Covid-19 pandemic is a situation that requires proper handling so that it does not spread further. Dissemination of Covid-19 information is one of the steps taken by the communication and informatics department of Payakumbuh (Diskominfo) to increase public participation by providing knowledge and changing people's attitudes to be able to take steps to prevent Covid-19. This study aims to determine the form of communication strategy of The Communication and Informatics Department of Payakumbuh in disseminating information on Covid-19 with supporting factors and inhibiting factors in its implementation. This research uses a qualitative approach with constructivism paradigm. The theory used in this study is the theory of diffusion of innovation. Data collection techniques were carried out through in-depth and semi-structured interviews, as well as observation. The results of the study show that the form of communication strategy is the stages of compiling communicants or communication targets, messages in the dissemination of Covid-19 information, media selection, determining the frequency of information dissemination, the role of communicators, and public response to the dissemination of information on Covid-19. One of the supporting factors in the dissemination of Covid-19 information is that The Communication And Informatics Department Of Payakumbuh’s public relations officer has understood the use of information and communication technology, thus facilitating the dissemination of Covid-19 information through new media, and one of the inhibiting factors is the lack of coordination at The Communication and Informatics Department Of Payakumbuh in managing the website, and the unopenness of hospital management in Payakumbuh in providing information updates on Covid-19 in Payakumbuh City.

The wide range of social hot news events on the Internet has made the Internet have a great impact on the public. However, there are few studies on Internet information. In order to improve the efficiency of user network information dissemination of Internet information based on complex network theory and model simulation, this paper makes a more in-depth study on information dissemination on the Internet, constructs a complex network of Internet information dissemination, and analyzes the static topology and dynamic evolution process of the network. Using the attention relationship between Internet users, the Internet information dissemination network, degree, and path were used to select multiple indicators. The static topology of the network is analyzed by using the complex network theory. The study found that the complex network of Internet information is different from other complex networks. The influencing factors of network dynamic evolution are studied from three aspects: overall structure, local structure, and time constraints. The evolution trend of different forms and overall network nodes in the evolution process was explored, and the network dynamic evolution process model was constructed. Practice shows that the model can better describe the evolution process of network information dissemination in complex networks. The degree values of the two networks are positively correlated with the corresponding average clustering coefficients, and the networks have a significant hierarchy. The correlation between news hot events and network nodes is not as good as users’ attention to the network.

Full textAbstract:
This article examines one of the approaches to the formalization of information dissemination processes based on the diffusion-limited aggregation model, using elements of cellular automata and their analogs. The model describes the dynamics of the information dissemination process without the influence of the mass media by taking into account the facts of information exchange that occurs during communication between participants of an arbitrary target audience. It is believed that the process is characterized by the property of self-similarity. An approach is proposed that makes it possible to study the dynamics of information dissemination processes, taking into account the attitude of the group members to each other and the attitude of the participants to the input information. As a result, an assessment of the effectiveness of the information dissemination process was obtained, which allows drawing conclusions regarding the success of information promotion measures. To demonstrate the processes of information dissemination modeled on the basis of the approach, the results of numerical experiments are presented, in which the implementation of the information exchange procedure for each person is limited to three members of the target group.

Quantitative analysis on human behavior, especially mining and modeling temporal and spatial regularities, is a common focus of statistical physics and complexity sciences. The in-depth understanding of human behavior helps in explaining many complex socioeconomic phenomena, and in finding applications in public opinion monitoring, disease control, transportation system design, calling center services, information recommendation. In this paper,we study the impact of human activity patterns on information diffusion. Using SIR propagation model and empirical data, conduct quantitative research on the impact of user behavior on information dissemination. It is found that when the exponent is small, user behavioral characteristics have features of many new dissemination nodes, fast information dissemination, but information continued propagation time is short, with limited influence; when the exponent is big, there are fewer new dissemination nodes, but will expand the scope of information dissemination and extend information dissemination duration; it is also found that for group behaviors, the power-law characteristic a greater impact on the speed of information dissemination than individual behaviors. This study provides a reference to better understand influence of social networking user behavior characteristics on information dissemination and kinetic effect.

Full textAbstract:
This article contrasts different perspectives concerning the diffusion of earthquake knowledge among non-scientific audiences. The perspective that underlies much of current information dissemination efforts is a “producer-user” model. This model assumes a stable set of knowledge producers and an identifiable set of knowledge users. An alternative perspective is an “issue networks” model. This model assumes a more fluid set of actors and issues linked by common concerns about earthquake hazards. This latter model is suggested as a more accurate depiction of knowledge diffusion within the state and local earthquake policy arenas. This portrayal also leads to consideration of new strategies for disseminating seismological, earthquake engineering and related knowledge.

Full textAbstract:
This paper is dedicated to exploring the dynamical behavior of information diffusion in the Device-to-Device (D2D) communication environment for information security, so as to study how to accelerate the dissemination of beneficial information and curb the spread of malicious information. A mathematical model of information diffusion considering the combined impact of user awareness and social tie between users is proposed. The equilibrium of the model and its stability are fully analyzed. Very importantly, there is a unique (viral) equilibrium that is globally asymptotically stable without any preconditions. This means that the spread of malicious information in the D2D communication environment cannot be completely eliminated whatever measures are taken, but its diffusion scale can be controlled by adjusting the value of the equilibrium, and then the goal of pursuing the best control effect at the minimum cost can be achieved. In the same way, the dissemination scale of beneficial information can be expanded. Finally, the obtained main theoretical results are illustrated by some examples, and some suggestions are also given.

With the development of social networks, the complexity of the factors affecting the users’ information dissemination is increasing and the complexity of online social networks and influencing factors of individual behaviors and attitudes make the development of online public opinion present a dynamic, complex, and multifactor evolution. Analyzing the influencing factors of public opinion dissemination is conducive to optimize company management and information diffusion management. However, there has been no comprehensive analysis of the complex factors that influence the dissemination of information; this study focused on synthesizing 20 empirical studies on the influencing factors of China public opinion dissemination from the perspective of the user, and a meta-analysis was conducted. We establish the influencing factors of users’ information adoption model from three aspects of information source reliability, perceived information quality, and the heat of public opinion events based on elaboration likelihood model. The results indicated that the main influencing factors of public opinion communication are authority, reliability, quality of information form, quality of information editing, quality of information utility, and event attendance preference. Among the factors, authority and quality of information editing have more significant impacts on users’ information adoption behavior in the dissemination of public opinion. In addition, whether the type of event was a public emergency had a moderating effect. The results are helpful to explore the universality of the influencing factors so as to help related regulators better build a multiangle supervision mechanism and conduct early warning of information diffusion.

Full textAbstract:
Social media, especially the microblogs, emerge as a part of our daily life and become a key way to information spread. Thus, information dissemination in the microblog became a research hotspot. Based on some principles that are summarized from the microblog users’ behaviors, this paper proposes a dynamic microblog network model. Through simulations this network has the features of periodicity of average degree, high clustering coefficient, high degree of modularity, and community. Besides, an information dissemination model through “@” in the microblog has been presented. With the microblog network model and the zombie-city model, this paper has modelled an artificial microblog and has simulated the information dissemination in the artificial microblog with different scenes. Therefore, some interesting findings have been presented. (1) Due to a better connectivity, information could spread widely in a random network; (2) information spreads more quickly in a stable microblog network; (3) the decay rate of the relationships will have an effect on information dissemination; that is, with a lower decay rate, information spreads more quickly and widely; (4) the higher active level of users in microblog could promote information spread widely and quickly; (5) the “@” mode of information dissemination makes a high modularity of the information diffusion network.

Aiming at the problem that the existing rumor dissemination models only focus on the characteristics of rumor dissemination and ignore anti-rumor dissemination, an evolution game model, SDIR, based on heat influence is proposed in this paper. Firstly, in order to solve the problem that rumor and anti-rumor information of emergency events disseminate simultaneously in social networks, the model extracts the factors that affect information dissemination: user behavior characteristics, user closeness and heat influence of participating topics. Secondly, anti-rumor information and an evolutionary game mechanism are introduced into the traditional SIR model, binary information is introduced to analyze the anti-rumor dissemination model SDIR, and the four state transitions and dissemination processes of SDIR are discussed. Finally, the SDIR model is experimentally validated in different datasets and dissemination models. The experimental results show that the SDIR model is in line with the actual dissemination law, and it can be proved that high self-identification ability plays a certain role in suppressing rumors; the anti-rumor information effectively inhibits the spread of rumor information to a certain extent. Compared with other models, the SDIR model is closer to the real diffusion range in the dataset.

Online platforms have become the primary source of information about scientific advances for the wider public. As online dissemination of scientific findings increasingly influences personal decision-making and government action, there is a growing necessity and interest in studying how people disseminate research findings online beyond one individual platform. In this paper, we study the simultaneous diffusion of scientific articles across major online platforms based on 63 million mentions of about 7.2 million articles spanning a 7-year period. First, we find commonalities between people sharing science and other content such as news articles and memes. Specifically, we find recurring bursts in the coverage of individual articles with initial bursts co-occurring in time across platforms. This allows for a ranking of individual platforms based on the speed at which they pick up scientific information. Second, we explore specifics of sharing science. We reconstruct the likely underlying structure of information diffusion and investigate the transfer of information about scientific articles within and across different platforms. In particular, we (i) study the role of different users in the dissemination of information to better understand who are the prime sharers of knowledge, (ii) explore the propagation of articles between platforms, and (iii) analyze the structural virality of individual information cascades to place science sharing on the spectrum between pure broadcasting and peer-to-peer diffusion. Our work provides the broadest study to date about the sharing of science online and builds the basis for an informed model of the dynamics of research coverage across platforms.

Axelrod's model describes the dissemination of a set of cultural traits in a society constituted by individual agents. In a social context, nevertheless, individual choices toward a specific attitude are also at the basis of the formation of communities, groups and parties. The membership in a group changes completely the behavior of single agents who start acting according to a social identity. Groups act and interact among them as single entities, but still conserve an internal dynamics. We show that, under certain conditions of social dynamics, the introduction of group dynamics in a cultural dissemination process avoids the flattening of the culture into a single entity and preserves the multiplicity of cultural attitudes. We also consider diffusion processes on this dynamical background, showing the conditions under which information as well as innovation can spread through the population in a scenario where the groups' choices determine the social structure.

Abstract This article explores the structure of connections between the hospitals that are members of a hospital management innovation and learning network. This study was based on the assumption that there are limitations to encourage the communication and diffusion of knowledge between health service organizations if they are not effectively connected through social networks. Social Network Analysis was used as a strategy for monitoring the dissemination of information between hospitals. Theoretical concepts of diffusion of knowledge allowed emphasizing the role of the phenomena and communication and learning processes as the driving forces for health service innovation. The results showed weak interactions between hospitals and a lack of cohesion within the network. Therefore, there is a need for policies to promote the flow of data and information, which requires network openness to foster the exchange of innovative processes. Interactions between these hospitals in horizontal and disseminated structures have yet to be stimulated, established, incorporated, and developed by individuals, institutions and health service organizations.

Full textAbstract:
In recent years, social networks have played a strong role in diffusing information among people all around the globe. Therefore, the ability to analyse the diffusion pattern is essential. A diffusion model can identify the information dissemination pattern in a social network. One of the most important components of a diffusion model is information perception which determines the source each node receives its information from. Previous studies have assumed information perception to be just based on a single factor, that is, each individual receives information from their friend with the highest amount of information, whereas in reality, there exist other factors, such as trust, that affect the decision of people for selecting the friend who would supply information. These factors might be in conflict with each other, and modelling diffusion process with respect to a single factor can give rise to unacceptable results with respect to the other factors. In this article, we propose a novel information diffusion model based on non-dominated friends (IDNDF). Non-dominated friends are a set of friends of a node for whom there is no friend better than them in the set based on all considered factors, considering different factors simultaneously significantly enhance the proposed information diffusion model. Moreover, our model gives a chance to all non-dominated friends to be selected. Also, IDNDF allows having partial knowledge by each node of the social network. Finally, IDNDF is applicable to different types of data, including well-known real social networks like Epinions, WikiPedia, Advogato and so on. Extensive experiments are performed to assess the performance of the proposed model. The results show the efficiency of the IDNDF in diffusion of information in varieties of social networks.

The article discusses a technique for constructing a model and a method for finding solutions in the problem of imitating the process of information dissemination based on the use of a boundary value problem for a fractional differential equation in partial derivatives. It is proposed to use the analogy technique for modeling information dissemination processes, which is based on the use of the features of a fractional analysis and the diffuse nature of information penetration processes. A method for constructing hybrid models is proposed, which makes it possible to take into account changes in the interval of values of the spatial variable over time. Homogeneous and inhomogeneous models of diffusion processes are considered, which make it possible to numerically obtain and analyze experimental data for solving problems of monitoring the levels of information dissemination in social groups.

Purpose Social media have attracted attention as an information channel for content generated in heterogeneous internet services. Focusing on social media platforms, the purpose of this paper is to examine the factors behind social transmission with content crossover from other services through hypertext link (URL). The authors investigate the effects of source influence and peer referrals on diffusion outcome and address their variations in the case of content crossover. Design/methodology/approach The authors use a Poisson regression model due to the discrete nature of the dependent variable. The authors conduct an empirical study using 233 million real transaction data generated by 1,203,196 Korean users of Twitter. Findings Source influence and peer referral have a positive impact on cascade size in the content dissemination process. In the case of content crossover, the impact of source influence decreases. However, the impact of peer referrals increases in the process of external content dissemination. Research limitations/implications The authors demonstrate source and peer effects on content diffusion and that these effects vary when shared content is linked from an external service by a URL. Practical implications The findings indicate that firms that wish to diffuse information through social media or enter the social media with new services to provide new ways of creating and sharing content should understand the nature of the social transmission process. Originality/value Given the growing popularity of social media, particularly SNSs with online social networks as information channels, the authors first consider online social transmission as a user-driven diffusion process. Based on social factors in the diffusion process, the authors derive source and peer effects on the social transmission process.

Full textAbstract:
Social networks are formed by individuals, in which personalities, utility functions, and interaction rules are made as close to reality as possible. Taking the competitive product-related information as a case, we proposed a game-theoretic model for competitive information dissemination in social networks. The model is presented to explain how human factors impact competitive information dissemination which is described as the dynamic of a coordination game and players’ payoff is defined by a utility function. Then we design a computational system that integrates the agent, the evolutionary game, and the social network. The approach can help to visualize the evolution of % of competitive information adoption and diffusion, grasp the dynamic evolution features in information adoption game over time, and explore microlevel interactions among users in different network structure under various scenarios. We discuss several scenarios to analyze the influence of several factors on the dissemination of competitive information, ranging from personality of individuals to structure of networks.

Purpose As a new communication paradigm, social networking sites (SNS) have boosted information diffusion and viral marketing. Prior researchers have identified various factors affecting information dissemination on SNS. However, they often focus on limited factors and there is a lack of an integrated theoretical framework that explains aspects of relevant factors. Besides, the research on the impacts of relationships on individual retweeting behavior is still controversial. The purpose of this paper is to propose a theoretical framework to systematically investigate the determinants of individual dissemination behavior on SNS based on the elaboration likelihood model (ELM). Moreover, the authors also examine the relative importance of those relevant factors. Design/methodology/approach The authors randomly selected 1,250 members of Twitter and crawled posts published by each member since he/she created the Twitter account using Twitter API. The authors processed the data to create panel data and tested hypotheses with the panel logit model. Findings Factors both on the central route and on the peripheral route of ELM have positive impacts on individual dissemination behavior. Among them, information receiver-related factor and relationships-related factors are the most influential. Contrastingly, source-related factors are the least influential. Furthermore, the authors find that social tie strength mediates almost 50 percent of the effect of value homophily on individual dissemination behavior. Originality/value The authors are the first to directly apply ELM to examine individual dissemination behavior on SNS. By integrating factors into the two information processing routes, They incorporate relevant factors into the model and systematically analyze their impacts on individual retweeting behavior on SNS. The research offers at least one explanation for the contradictory findings about the effect of homophily on individual sharing behavior in previous research. The authors propose new variables that gauge topical relevance and interpersonal value homophily on SNS.

Corporate negative events have been frequently exposed in the information age. Research on the dissemination mechanism of negative emotional information for netizens contributes corporates to monitor public opinion trends and resolve public opinion crises. Combining emotional infection theory and the classic infectious disease model, we first divided emotional communication stage into individual and group propagation stages and constructed the SEI1I2R model of negative emotional information communication among netizens under corporate negative events. Then, we performed the model analysis and simulation. Results indicated that trust and communication conversion rates are in direct proportion to negative emotional diffusion speed; corporate response rate is inversely proportional to negative emotional diffusion speed; however, the effects of self-regulation are insignificant.

Full textAbstract:
Integrated Pest Management (IPM) is a holistic approach in reducing damage caused by pests without harming the environment. A study on cost effectiveness strategy to disseminate IPM technology was conducted in the Banke and Surkhet districts of Nepal. For assessing the spread of information, farmers were asked a series of questions during the survey to determine knowledge of IPM and degree of IPM adoption. Using descriptive statistics and differences in means, analysis was done on relationships among access to information, IPM knowledge and adoption, and word-of-mouth diffusion of IPM techniques to neighboring farmers. For the evaluation of dissemination methods efficiency and to examine the cost for using the different dissemination methods of IPM technology followed by IPM IL project in Banke and Surkhet district, the cost measurements was focused only on the dissemination methods of IPM technology with a public cost such as mass media, agricultural officers, MPC, collection centre, FFS, CBFs, cooperatives, neighboring farmers, agro-vets and field days. When the number of farmers needing to receive training for one farmer to adopt IPM practices is known, and then that value can be multiplied by the cost per farmer trained which allows in providing the cost per farmer adopting the technology by transfer method. Capacity building in IPM technology development and dissemination in the study area was I/NGOs working in that area. Market Planning Committee of Banke and Surkhet district has played a vital role in disseminating IPM technology in cost effective and efficiently.

The construction industry is undergoing a digital transformation, with the goal of developing long-term solutions that promote construction companies’ alignment with market demands and that empower them to reduce production losses as much as possible. The purpose of this paper was to evaluate a gamified model for disseminating production information in the construction industry using visual management. This was a qualitative exploratory study that employed the Design Science methodology and the Design Science Research method. The model was designed, developed, and evaluated by 35 people, including 10 off-site users who focused on usability, user experience, and model promotability, 15 engineers, and 10 workers who considered user experience and promotability. Employees and managers thought the model was excellent, while outside users thought it was good. Furthermore, the evaluators made suggestions for improvements aimed at achieving excellence. We conclude that the proposed model improves production information dissemination in construction by considering the target audience’s digital inclusion and knowledge diffusion within work teams.

Full textAbstract:
This study constructs the network diffusion model of food safety scare behavior under the effect of information transparency and examines the network topology and evolution characteristics of food safety scare behavior in a numerical simulation. The main conclusions of this study are as follows. (1) Under the effect of information transparency, the network degree distribution of food safety scare behavior diffusion demonstrates the decreasing characteristics of diminishing margins. (2) Food safety scare behavior diffusion increases with the information dissemination rate and consumer concern about food safety incidents and shows the characteristics of monotone increasing. And with the increasing of the government food safety supervision information transparency and media food safety supervision information transparency, the whole is declining characteristic of diminishing marginal. In addition, the extinction of food safety scare behavior cannot be achieved gradually given a single regulation of government food safety supervision information transparency and media food safety supervision information transparency. (3) The interaction effects between improving government food safety supervision information transparency or media food safety supervision information transparency and declining consumer concerns about food safety incidents or information transmission rate can engender the suppression of food safety scare behavior diffusion.

AbstractPrograms that disseminate information to health care practitioners often do so partly to encourage appropriate changes in practice. However, merely providing information is seldom enough to accomplish such changes. If information transfer programs are to influence practice, they must be designed to maximize the conditions facilitating change. Reliance on a diffusion model for thinking about how information reaches practitioners has led researchers to over-emphasize the importance of exposure to information and ignore other factors that determine whether change will occur, such as practitioners' motivation to change, the context in which clinical decisions are made, and how information is presented. The fact that successful dissemination will not necessarily produce change also has implications for how information transfer programs should be monitored and evaluated.

Ineffective knowledge dissemination contributes to clinical practice and service improvements not being realised. Meaningful knowledge translation can occur through the understanding and matching of appropriate communication mediums that are relevant for different stakeholders or audiences. To this end, we present a dissemination instrument, the ‘REAch and Diffusion of health iMprovement Evidence’ (README) checklist, for the communication of research findings, integrating both traditional and newer communication mediums. Additionally, we propose a ‘Strategic Translation and Engagement Planning’ (STEP) tool, for use when deciding which mediums to select. The STEP tool challenges the need for communicating complex and simple information against the desire for passive or active stakeholder interaction. Used collaboratively by academics and health professionals, README and STEP can promote co-production of research, subsequent diffusion of knowledge, and develop the capacity and skills of all stakeholders.

In political science, it is rarely possible to work with a topic of extremely significant social problems that has not yet found a proper understanding by the scientific community. This includes the concept of cognitive freedom, which already claims to be the new political freedom of the 21st century but is practically not represented in the scientific discourse. This article does not claim to be a complete theoretical and methodological representation of cognitive freedom as a political freedom, it is only an invitation to a discussion about its essence, features, practical significance, and many other aspects of this unique phenomenon. A review of publications on the topic of cognitive freedom from the point of view of psychological, neuro-ethical, epistemological, and cognitive trends is conducted; the degree of its study is evaluated; and the results obtained are summarized. The author's contribution to the understanding of cognitive freedom was the substantiation of the diffusive concept of cognitive freedom using a combination of two approaches: implicit cognitive science and political diffusionism. The diffusive concept of cognitive freedom can be formulated as follows: cognitive freedom is the freedom of representation, dissemination, and transmission of knowledge or information by individuals in diffusion networks. The concept “knowledge transfer” is introduced, meaning that its dissemination is carried out under conditions of some restriction of freedom in the form of prohibition, influence, pressure. This is the political nature of diffusion that acquires signs of managing or manipulating participants in the interaction. This concept should develop the concept of cognitive freedom in terms of one of the conditions for its implementation - the freedom to present, receive, distribute, and transmit knowledge in diffusion networks (a communication channel through which information and knowledge flow). The practical significance of the diffusive concept of cognitive freedom lies in its suitability for identifying the possibilities of managing the free process of political diffusion. Several cognitive technologies based on the principles of “cognitive control”, which in fact plays the role of a kind of “limiter” or even an obstacle to the freedom of obtaining, storing or distributing knowledge, are described. The types of cognitive technologies are identified: technologies for managing human cognitive abilities at the level of the unconscious, technologies for managing the process of organizing information, technologies for strategic narratives, and framing technology: technologies for managing mnemonic practices, technologies for controlling social media as communicators.

Abstract This paper proposes a new information dissemination and opinion evolution IPNN (Information Propagation Neural Network) model based on artificial neural network. The feedforward network, feedback network and dynamic evolution algorithms are designed and implemented. Firstly, according to the ‘six degrees separation’ theory of information dissemination, a seven-layer neural network underlying framework with input layer, propagation layer and termination layer is constructed; secondly, the information sharing and information interaction evolution process between nodes are described by using the event information forward propagation algorithm, opinion difference reverse propagation algorithm; finally, the external factors of online social network information dissemination is considered, the impact of external behavior patterns is measured by media public opinion guidance and network structure dynamic update operations. Simulation results show that the proposed new mathematical model reveals the relationship between the state of micro-network nodes and the evolution of macro-network public opinion. It accurately depicts the internal information interaction mechanism and diffusion mechanism in online social network. Furthermore, it reveals the process of network public opinion formation and the nature of public opinion explosion in online social network. It provides a new scientific method and research approach for the study of social network public opinion evolution.

Reducing fake news and rumor propagation through social media may be challenging to achieve when dealing with sensible contents and communities with free access to online shared resources. Controlling rumor dissemination and promoting true news are the main techniques used to strangle false information that may result in dramatic effect on human wellbeing in an open or closed environment. In this article, we studied a predator-prey model with constant delay in both predator and prey equations and applied the proposed model to the underlying relationship between the existing rumor propagating through social media and the related authoritative information containing the truth broadcast to reduce the respective rumor negative effect on the targeted community. We showed that the proposed system was very responsive to small perturbations and exhibited complex dynamical behavior around the steady-state equilibrium when interaction occurs and delay is applied, considering the controlled situations. Numerical results suggested applying relatively small delay, which represents the ideal time to publish the related propagating rumor curative content to reduce its diffusion speed and promote the truth.

Purpose With the popularity of the internet and the increasing numbers of netizens, tremendous information flows are generated daily by the intelligently interconnected individuals. The diffusion processes of different information are not independent, and they interact with and influence each other. Modeling and analyzing the interaction between correlated information play an important role in the understanding of the characteristics of information dissemination and better control of the information flows. This paper aims to model the correlated information diffusion process over the crowd intelligence networks. Design/methodology/approach This study extends the classic epidemic susceptible–infectious–recovered (SIR) model and proposes the SIR mixture model to describe the diffusion process of two correlated pieces of information. The whole crowd is divided into different groups with respect to their forwarding state of the correlated information, and the transition rate between different groups shows the property of each piece of information and the influences between them. Findings The stable state of the SIR mixture model is analyzed through the linearization of the model, and the stable condition can be obtained. Real data are used to validate the SIR mixture model, and the detailed diffusion process of correlated information can be inferred by the analysis of the parameters learned through fitting the real data into the SIR mixture model. Originality/value The proposed SIR mixture model can be used to model the diffusion of correlated information and analyze the propagation process.

This study was part of broader PhD research which investigated how access to, and use of, information enhances adaptation to climate change and variability in the agricultural sector in semi-arid Central Tanzania. The research was carried out in two villages using Rogers’ Diffusion of Innovations theory and model to assess the dissemination of this information and its use by farmers in their adaptation of their farming practices to climate change and variability. This predominantly qualitative study employed a post-positivist paradigm. Some elements of a quantitative approach were also deployed in the data collection and analysis. The principal data collection methods were interviews and focus group discussions. The study population comprised farmers, agricultural extension officers and the Climate Change Adaptation in Africa project manager. Qualitative data were subjected to content analysis whereas quantitative data were analysed to generate mostly descriptive statistics using SPSS.  Key findings of the study show that farmers perceive a problem in the dissemination and use of climate information for agricultural development. They found access to agricultural inputs to be expensive, unreliable and untimely. To mitigate the adverse effects of climate change and variability on farming effectively, the study recommends the repackaging of current and accurate information on climate change and variability, farmer education and training, and collaboration between researchers, meteorology experts, and extension officers and farmers. Moreover, a clear policy framework for disseminating information related to climate change and variability is required.

This study utilized social network analysis to identify the top 10 Twitter influentials during the Hurricane Irma crisis period and examined the relationship between social media attributes and the bridge influence of controlling information flow. The number of a user’s followers and tweets significantly predicted one’s control of information. Crisis information tended to be shared in scattered subgroups. Social network boundaries impeded information diffusion, and the communication pattern was largely one-way. The findings partially supported the opinion leader argument while indicating that influentials can directly generate information, which is consistent with the social-mediated crisis communication model. Such findings will contribute to crisis literature and help emergency management professionals advance social media usage to disseminate crisis information, build effective communication, and provide immediate disaster relief responses

Purpose Recent research on word-of-mouth (WOM) has presented consistent evidence on the importance of secondary WOM (sWOM) on online user-generated content (UGC) and on diffusion of positive and negative commercial information. The purpose of this paper is to investigate what motivates consumers to spread, via electronic WOM communication, negative information about commercial entities adversity using malicious verbal narratives. Based on concepts related to the joy of pain (schadenfreude) and gloating behavior the authors propose a set of hypotheses designed to test two key moderators (perceived deservingness and entity’s status) as well as the process of spiteful dissemination like content assimilation, dissemination time and duration. Design/methodology/approach The research consists on a series of four studies using different research methods (surveys and experiments) and a mix of quantitative and qualitative analyses. Findings Results show that actively communicating about others’ adversity (i.e. gloating behavior) provides an outlet to the passive observation of others’ adversity (i.e. schadenfreude feelings). Results indicate that schadenfreude and gloating are linked to the perceived deservingness of a commercial entity and entity status (the tall poppy syndrome). Results also show that malicious feelings and gloating behavior cause consumers to disseminate information more widely, more rapidly, for a longer period and frequently distort its content. Research limitations/implications The findings contribute to literature on WOM by introducing an approach that highlights the potential negative effects of WOM on the dissemination of commercial information that might harm the relevant commercial entity’s reputation and goodwill. Originality/value This study illuminates the prevalence of negative rhetoric in WOM and supports the theory schadenfreude motives as a trigger for gloating behavior in the form of disseminating negative, malicious and intense WOM regarding commercial setbacks. This research is the first to examine and demonstrates that when it comes to WOM communication, schadenfreude feelings and gloating behavior might play a central role in the dissemination of negative information and the two constructs’ role in understanding infostorms, the sudden flow of large quantities of negative WOM using strong gleeful exultation. This study is the first to examine these phenomena in the business setting.

Full textAbstract:
In this paper, a homogeneous continuous time Markov chain (CTMC) is used to model information diffusion or dissemination, also to determine influencers on Twitter dynamically. The tweeting process can be modeled with a homogeneous CTMC since the properties of Markov chains are fulfilled. In this case, the tweets that are received by followers only depend on the tweets from the previous followers. Knowledge Discovery in Database (KDD) in Data Mining is used to be research methodology including pre-processing, data mining process using homogeneous CTMC, and post-processing to get the influencers using visualization that predicts the number of affected users. We assume the number of affected users follows a logarithmic function. Our study examines the Indonesian Twitter data users with tweets about covid19 vaccination resulted in dynamic influencer rankings over time. From these results, it can also be seen that the users with the highest number of followers are not necessarily the top influencer.

The extreme levels of uncertainty and complexity surrounding disaster relief operations call for the rapid diffusion of information. Thus, to collect and share information, humanitarian organizations have become largely dependent on Internet-based social media platforms. This paper presented a field study examining the effective way information can be diffused for the coordination of relief local organizations during their response to the humanitarian crisis in Yemen. The study made use of a statistical method of quantitative to obtain the results through social media use in access decision-making information of response and promotion of social coordination among the local relief organizations and study of humanitarian needs and the equitable distribution of relief. This finding is indicating information posted on social media during a disaster was exhibited expediently compared to other means of dissemination that provides needed information at later disaster phases, however, the participation in the diffusion of information decreases with more communications.

This paper aims to explore the impact of user behavior on information diffusion in D2D (Device-to-Device) communications. A discrete dynamical model, which combines network metrics and user behaviors, including social relationship, user influence, and interest, is proposed and analyzed. Specifically, combined with social tie and user interest, the success rate of data dissemination between D2D users is described, and the interaction factor, user influence, and stability factor are also defined. Furthermore, the state transition process of user is depicted by a discrete-time Markov chain, and global stability analysis of the proposed model is also performed. Finally, some experiments are examined to illustrate the main results and effectiveness of the proposed model.

A Review of:
Rabina, D. L., & Walczyk, D. J. (2007). Information professionals’ attitude toward the adoption of innovations in everyday life. Information Research, 12(4), 1-15.
Objective – This study examined the general characteristics and patterns of librarians in connection with their willingness to adopt information and communication technologies.
Design – Online questionnaire.
Setting – General distribution to information professionals through online inquiry. More than 70% of responders worked in public or academic libraries.
Subjects – Librarians and library staff at mostly public and academic libraries.
Methods – The study was conducted during a two week period in April 2006 through an online questionnaire that was sent to library and librarian-related electronic mail lists. The questionnaire was divided into two parts and contained a total of 39 questions. Part one contained eight questions that asked for demographic data and the respondent’s daily attitude toward the adoption of information and communication technologies. Questions regarding age, number of years worked in a library, career, type of library environment worked in, and primary responsibilities within that environment were asked. For one question the respondents were asked to identify which of the categories they fall under when adopting a new technology. The results from part one were used to consider the innovativeness of librarians. The results from part two were used for a study of opinions on innovations and their relative advantage.
Main Results – A total of 1,417 responses were received. Of those, 1,128 were fully completed and considered valid and used for inquiry. The majority of respondents worked in public or academic libraries. Nine hundred and twenty-six respondents, or 88%, were from the U.S. and represented more than 300 distinct zip codes. Two hundred and two respondents, or 12%, were international respondents.
This study notes that the sociologist, Everett Rogers, identified and defined five adopter categories in 1958. Those categories are: innovators, early adapters, early majority, late majority, and laggards. The findings of this study indicate that regardless of the demographic variables considered, more than 60% of respondents, the majority of librarians surveyed, fall into two contrasting adapter categories: early adopters and early majority. The study suggests that the efficient and effective diffusion of new technologies in library settings may be difficult. Three problematic areas among librarians for the dissemination of innovation were identified: conflicting opinions among multiple opinion leaders, deceleration in the rate of adoption, and improper re-invention. The findings of the study also suggest that “contrary to common beliefs, librarians in academic or special libraries are no more innovative than public or school librarians” (Conclusion, ¶3).
Conclusion – The study concludes that librarians’ attitudes are unevenly distributed with most either accepting new innovations or being late adopters. The variables of age, role, tenure, and library type had little impact on the approach of the professional toward innovation. The identification of the three problem areas: opinion leadership, deceleration of adoption, and improper re-invention, represents where more time and effort may need to be spent to make the implementation of new technology a smoother process.
