The Impact

The existing opinion dynamics models mainly concentrate on the impact of opinions on other opinions and ignore the effect of the social similarity between individuals. Social similarity between an individual and their neighbors will also affect their opinions in real life. Therefore, an opinion evolution model considering social similarity (social-similarity-based HK model, SSHK model for short) is introduced in this paper. Social similarity is calculated using individual properties and is used to measure the social relationship between individuals. By considering the joint effect of confidence bounds and social similarity in this model, the role of neighbors’ selection is changed significantly in the process of the evolution of opinions. Numerical results demonstrate that the new model can not only obtain the salient features of the opinion result, namely, fragmentation, polarization, and consensus, but also achieve consensus more easily under the appropriate similarity threshold. In addition, the improved model with heterogeneous and homogeneous confidence bounds and similarity thresholds are also discussed. We found that the improved heterogeneous SSHK model could acquire opinion consensus results more easily than the homogeneous SSHK model and the classical models when the confidence bound was related to the similarity threshold. This finding provides a new way of thinking and a theoretical basis for the guidance of public opinion in real life.

The Impact

This chapter focuses on a method, social network analysis (SNA) that can be used to assess the quantity and quality of connection, communication and collaboration mediated by social tools in an organization. An organization, in the Canadian public sector, is used as a real-life case study to illustrate how SNA can be used in a pre-test/post-test evaluation design to conduct a comparative assessment of methods that can be used before, during and after the implementation of organizational change in work processes. The same evaluation method can be used to assess the impact of introducing new social media such as wikis, expertise locator systems, blogs, Twitter and so on. In other words, while traditional pre-test/post-test designs can be easily applied to social media, the social media tools themselves can be added to the assessment toolkit. Social network analysis in particular is a good candidate to analyze the connections between people and content as well as people with other people.

Incorporating decision-making capability as an intelligence aspect into crowd dynamics models is crucial factor for reproducing realistic pedestrian flow. Crowd dynamics models are still suffering from poor representation of essential behaviors such as lane changing behavior. In this article, we provide the simulated pedestrians in the social force model more intelligence as an extension to the pedestrian’s investigation capability in bidirectional walkways, to let the model appear more representative of what actually happens in reality. In the proposed model, the lane’s structure is modeled as social network. Thereby, the simulated pedestrians with inconvenient walking can detect the available lanes inside his environment, investigate their attractions, and then make decisions to join the most attractive one. Simulations are performed to validate the work qualitatively by tracing the behavior of the simulated pedestrians and studying the impact of this behavior on lane formation. Finally, a quantitative measurement is used to study the effect of our contribution on the pedestrians’ efficiency of motion.

IntroductionPeople with schizophrenia exhibit deficits in neurocognitive and social cognitive (SC) processes which limit their social reintegration. SC was found to mediate in part the impact of neurocognitive dysfunctions on real-life functioning.ObjectiveThe purpose of this study was to implement a new intervention for patients with schizophrenia, the Social Cognition Individualized Activities Lab (So.C.I.A.L.) which trains both social cognition and neurocognitive functions.AimsTo determine the efficacy of the So.C.I.A.L in improving SC by a comparison with a validated cognitive remediation (CR) intervention: the Social Skills And Neurocognitive Individualized Training (SSANIT).MethodsNine stabilized patients accepted to participate in this pilot study. Five were randomized to So.C.I.A.L. and 4 to SSANIT. The two programs were matched for the overall treatment duration (20 weeks), as well as frequency and duration of the sessions. Both interventions included individual sessions of neurocognitive individualized training; So.C.I.A.L included group sessions on Emotion Recognition and Theory of Mind, while SSANIT group sessions of Social Skills Individualized Training.ResultsNo group difference was found for changes in neurocognition, while a significant group effect was observed for changes in SC, due to improvement only in the So.C.I.A.L. group.ConclusionsThe study results showed a specific effect of the So.C.I.A.L. on SC, beyond the effect on neurocognition. Further studies are needed to assess the impact of So.C.I.A.L. on real-life functioning in a larger group of subjects.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Second Largest Eigenvalue

We analyze the convergence time of opinion dynamics in a social network with community structure. Using matrix analysis, we prove that the convergence time is determined by the second largest eigenvalue modulus. This modulus is close to 1 if the social influence matrix is nearly uncoupled. Furthermore, we discuss and analyze the factors of community structure affecting the convergence time.

Abstract The question of racial “purity” or “identity” was part of the fashionable discussion on human races in the 1930s. In 1938 a debate over Chopin’s “racial identity” took place in the Warsaw press, triggered by the publication a book entitled Polacy-chrześcijanie pochodzenia żydowskiego (Poles — Christians of Jewish Origin) by Mateusz Mieses, an outstanding Judaist and representative of one of Poland’s Jewish communities. Mieses’ aim was to familiarise the Polish reader with the very little-known scale on which the ethnically Jewish element had penetrated over the many centuries into the families of the Polish landed gentry, intelligentsia and even aristocracy. As a result, Mieses claimed, many eminent Poles known in Polish history had some Jewish blood in their veins. In addition to the more or less convincing examples of such assimilation, Mieses also quotes some rather dubious ones, including the genealogy of Chopin. On the basis of unconfirmed rumours and the composer’s facial features in some unidentified portrait he claims that Chopin was half Jewish through his mother Justyna Krzyżanowska. Mieses’ conclusions — as well as his entire methodology — were sharply criticised by the reviewer of Wiadomości Literackie as well as by Zofia Lissa, at that time a young scholar at the threshold of a brilliant musicological career. Lissa pointed out that establishing Chopin’s “racial affiliation” is difficult for a lack of reliable and objective sources. For a long time all images of Chopin available to researchers had been either portraits or sculptures, which — as artistic creations — used to deform his face. However, Lissa argued that most of his portraits point to his Dinaric characteristics, which were also confirmed by the two surviving real-life likenesses of the composer (referred to by the author as “racially unprejudiced” sources) — namely, his death mask and the only surviving daguerreotype. Taking into account the findings of contemporary (mainly German) anthropology, Lissa concluded that Chopin was a typical Dinaric with some Nordic features, and it was from his mother that Fryderyk inherited his few physical traits characteristic of that type. On the other hand, Lissa denied that there was any connection between Chopin’s music and his “racial identity”. It seems a paradoxical that Lissa — a scholar of Jewish descent — drew on Nazi theories formulated by German anthropologists to show that Chopin had no demonstrable Jewish ancestors. But if we place this debate in the context of its time, and of one specific period in the ideological and scholarly evolution of Zofia Lissa herself — things do not look so simple any more. Her emphasis on the role of the social environment and her rejection of Einchenauer’s theses concerning the impact of “race” on the character of music testify to Lissa’s intensifying links to the Marxist-Leninist ideology, which she most likely began to absorb in that very period.

Introduction: The television is a landmark of scientific invention and amazing devices that has become an integral part of our life and it has revolutionized the world of communication. According to same studies children at the age of 6 years watch television daily for 3-4 hours on an average. The increasingly competitive economy is creating an environment where parents are forced to spend longer hours at work and fewer hours with their children . As result outside influences have greater access and influence over our children than ever before. The internet and media are bringing the outside world into your home . It influence the children every day and leads to the negative effects . television will escapes the children from real life and enter into a fantasy world and it inactivates the study image of schoolchildren and television will avoids the social interaction with other and alsi it’s a time consuming activity. Design: Descriptive research design. Participinats: 300 group of mothers were selected using non probability convenient sampling technique. Tool: self structured questionnaire. Result: study show that out of 300group , in pretest mean was 7.12 . The pre test standard deviation was 4.35. The mean difference was 11.33 and the obtained t-value was 16.86 which are significant at 0.005 levels. Hence, the stated hypothesis was accepted. Conclusion: Mother having poor knowledge about the impact of television viewing on behaviour 6-12 year children.

This chapter examines one of nine critical forces behind purchase decisions that make mobile advertising so powerful: social dynamics. Recent studies have shown that the social company we keep changes our behavior. This is our social context. Beyond our individual location at any given time, our social context influences how we interact in real life as part of a group of friends, as a couple, or with family members. And these behaviors are fundamentally different than how we behave when we are on our own. The chapter discusses the impact of social dynamics on mobile purchases, the importance of group composition, and digging deeper into consumers' personalities.

Considering the impact that physical distance and other properties have on the change of opinions, this paper introduces an intension model of the Hegselmann-Krause (KH) model—heterogeneous interaction (HI) model. Based on the classical KH model, HI model designs new interaction rules and the interactive radius considering the impact of heterogeneous attributes, such as physical distance, individual conformity, and authority. The experiment results show that the opinion evolution of the HI model will be similar to the classic KH model when the interactive radius is above the particular threshold value (σ>600). Unlike the KH model, which leads to the polarization phenomenon; most agents reach a consensus in HI model when the confidence radius equals 0.2, and the interactive radius remains within regulatory limits (150<σ<520). The conclusions show that interactive radius affects public opinion evolution. HI model can explain more conscious opinion evolution in real life and has significance that effectively guides public opinion.

Bots Impact Opinions in Social Networks: Let’s Measure How Much There is a serious threat posed by bots that try to manipulate opinions in social networks. In “Assessing the Impact of Bots on Social Networks,” Nicolas Guenon des Mesnards, David Scott Hunter, Zakaria el Hjouiji, and Tauhid Zaman present a new set of operational capabilities to detect these bots and measure their impact. They developed an algorithm based on the Ising model from statistical physics to find coordinating gangs of bots in social networks. They then created an algorithm based on opinion dynamics models to quantify the impact that bots have on opinions in a social network. They applied their algorithms to a variety of real social network data sets. They found that, for topics such as Brexit, the bots had little impact, whereas for topics such as the U.S. presidential debate and the Gilets Jaunes protests in France, the bots had a significant impact.

Workplace Outcomes

Interpersonal accuracy, the ability to correctly assess other people’s states or traits, has been studied for over 60 years, and many correlates have been uncovered. Furthermore, theorists routinely propose that having this kind of skill matters for social and workplace outcomes. However, much of the empirical work concerned with interpersonal accuracy does not directly address real-life outcomes for people who have, or lack, this skill. The present article summarizes literature pointing to behavioral correlates of interpersonal accuracy and illustrates when and why interpersonal accuracy is related to favorable interaction outcomes. There seems to be no specific behavior associated with high interpersonal accuracy. Instead, interpersonal accuracy seems to foster behavioral adaptability, the ability to change one’s behavior to match the expectations of the social interaction partner. This behavioral adaptability might be responsible for the positive interaction outcomes related to interpersonal accuracy. We illustrate the mechanism and boundary conditions underlying and framing how interpersonal accuracy affects interaction outcomes and discuss future directions in research on interpersonal accuracy.
