Human Computation and Convergence

Humans are the most effective integrators and producers of information, directly and through the use of information-processing inventions. As these inventions become increasingly sophisticated, the substantive role of humans in processing information will tend toward capabilities that derive from our most complex cognitive processes, e.g., abstraction, creativity, and applied world knowledge. Through the advancement of human computation - methods that leverage the respective strengths of humans and machines in distributed information-processing systems - formerly discrete processes will combine synergistically into increasingly integrated and complex information processing systems. These new, collective systems will exhibit an unprecedented degree of predictive accuracy in modeling physical and techno-social processes, and may ultimately coalesce into a single unified predictive organism, with the capacity to address societies most wicked problems and achieve planetary homeostasis.Comment: Pre-publication draft of chapter. 24 pages, 3 figures; added references to page 1 and 3, and corrected typ

Collective emotions online and their influence on community life

E-communities, social groups interacting online, have recently become an object of interdisciplinary research. As with face-to-face meetings, Internet exchanges may not only include factual information but also emotional information - how participants feel about the subject discussed or other group members. Emotions are known to be important in affecting interaction partners in offline communication in many ways. Could emotions in Internet exchanges affect others and systematically influence quantitative and qualitative aspects of the trajectory of e-communities? The development of automatic sentiment analysis has made large scale emotion detection and analysis possible using text messages collected from the web. It is not clear if emotions in e-communities primarily derive from individual group members' personalities or if they result from intra-group interactions, and whether they influence group activities. We show the collective character of affective phenomena on a large scale as observed in 4 million posts downloaded from Blogs, Digg and BBC forums. To test whether the emotions of a community member may influence the emotions of others, posts were grouped into clusters of messages with similar emotional valences. The frequency of long clusters was much higher than it would be if emotions occurred at random. Distributions for cluster lengths can be explained by preferential processes because conditional probabilities for consecutive messages grow as a power law with cluster length. For BBC forum threads, average discussion lengths were higher for larger values of absolute average emotional valence in the first ten comments and the average amount of emotion in messages fell during discussions. Our results prove that collective emotional states can be created and modulated via Internet communication and that emotional expressiveness is the fuel that sustains some e-communities.Comment: 23 pages including Supporting Information, accepted to PLoS ON

Magic mirror on the wall: Selfie-related behavior as mediator of the relationship between narcissism and problematic smartphone use

Objective: Recent research has suggested that problematic smartphone use is associated with several psychological factors and that mobile apps and smartphone-related behavior (i.e. selfi e behavior) may encourage the development of problematic smartphone use. However, little is known about how the interplay between dysfunctional personality characteristics and selfi e-related behavior can infl uence problematic smartphone use. The aim of this study was to examine the relationship between narcissism and problematic smartphone use, as well as the mediating role of selfi e-related behavior in this relationship among young men and women. Method: In the current study, a total of 627 undergraduate students (283 males and 344 females) completed a cross-sectional survey. A structural equation model was tested separately for males and females in order to evaluate the associations between narcissism, selfi e-related behavior and problematic smartphone use. Results: The results showed that greater narcissism was related to increased selfi e-related behavior, which in turn were positively associated with problematic smartphone use both for males and females. However, selfi e-related behavior mediated the relationship between narcissism and problematic smartphone use only for females. Conclusions: The study provides fresh insight into our understanding of the psychological mechanisms underlying problematic smartphone use, which may inform prevention and treatment interventions

Internet addiction and loneliness among children and adolescents in the education setting: an empirical pilot study

Research into various behavioural addictions has shown that such behaviour can negatively impact psychological wellbeing. One behavioural addiction that has been increasingly studied empirically is that of Internet Addiction (IA). Despite general consensus concerning the negative effects of IA on mental health and other indices of physical and psychosocial health, little research has been done in child and adolescent populations in specific contexts. The main objectives of this study were to (i) investigate the extent of problems caused by IA in children and adolescents, (ii) determine the socio-demographic and behavioural characteristics of children and adolescents with IA, and (iii) to provide a model capable of predicting IA in the educational context among the target population. A total of 131 Portuguese school children and adolescents participated in this study. Results indicated a relatively high incidence of IA in the sample (13%). Additionally, the correlational analyses revealed associations between IA and loneliness, social loneliness, and other variables related to the educational context. Results demonstrated that IA could be predicted using a model encompassing three variables (i.e., weekly Internet usage, loneliness, and classroom behaviour). Overall, the present findings corroborated results from other studies and added to the behavioural addiction literature by examining a younger cohort than previous empirical studies

The internet and sexual offending: an international perspective

Although the sexual abuse of children is a long-standing problem that has received considerable scholarly attention, still little is understood about sex offenses that occur by means of, or are facilitated through, the Internet. Increasing awareness of the Internet as a platform for the perpetration of sexual crimes has raised new questions on this aspect of criminal behavior. Of interest, for example, is whether those who engage in Internet-related sex crimes are a distinct type of sexual offender, or whether these offenders “merely” use newer technological methods to facilitate or perpetrate offenses. Moreover, little is known about the patterns, motivations, or typological similarities among types of individuals who use the Internet to commit sexual crimes. Of further concern is the risk posed by this class of sexual offenders, particularly the extent or rate at which those with an Internet-based conviction will escalate to (or have already engaged in) other types of sexual offences, especially “hands on” or contact sexual offenses. In reviewing the current empirical literature and drawing attention to areas of research need, this chapter addresses these and other pertinent questions related to use of the Internet in the commission of sexual offenses This chapter also draws focus to the importance of international cooperation, including policing, industry, (e.g., Internet Service Providers [ISPs], finance companies), and non-governmental organizations (NGOs), in the control and persecution of these offenses. Given the still limited empirical knowledge in this area, coupled with the inherently global nature of the Internet and the pace of technological advancement, the prosecution of Internet-based sexual crimes poses unique challenges that require thoughtful and rigorous scholarly attention

Social media and eating disorder psychopathology: a systematic review

The relationship between socialization through social media (SM) and eating disorders (EDs) is a serious problem for public health, largely affecting the mental health of younger people. This work aimed to identify scientific works addressing ED psychopathologies, studying their relationship with SM usage. In this systematic review, we analyze the available scientific evidence, thereby providing tools for intervention, prevention, and treatment. A systematic review and PRISMA analysis of narrative syntheses was carried out. Works were selected from the databases of Web of Science, Scopus, PubMed, and PsycINFO. Out of a total of 257 references, 19 articles were identified and selected; among them, correlational studies predominated. A growing interest in the subject matter was identified, as it is undergoing constant changes. The investigations found that EDs and SM usage are influenced by the time spent on SM, the type of interactions, and shared photographs, as well as gender and sociocultural context

Online Stress and Offline Stress:Uniqueness, Differences, and Cumulative Effects on Multiple Well-Being Outcomes

There is an increasing interaction between our offline and online lives, which puts forward a challenge to understanding the relationship between stress and health, as online and offline stress may be mixed. This study used 4,127 adolescents to test the uniqueness of online stress, the distinction between online and offline stress, and their co-occurrence and cumulative effects. The results showed that after controlling for offline stress, online stress still contributed to multiple well-being outcomes. Correspondence analysis revealed that online stress was more similar to daily hassles/perceived stress (global stress) compared to major life events. Latent profile analysis (LPA) revealed that adolescents who experienced certain levels of offline stress also experienced similar levels of online stress, indicating that they co-occur. Besides, the predictions of online and the three types of offline stress are consistent with the cumulative damage hypothesis of stress. Its theoretical and practical implications are discussed

Traditional Bullying and Cyberbullying Victimization Independently Predict Changes in Problematic Internet Gaming in a Longitudinal Sample.

PURPOSE Bullying and problematic Internet gaming (PIG) are two concerning phenomena among adolescents. Research suggests an association between them; however, longitudinal studies are scarce. Therefore, this study examined whether traditional and cybervictimization are prospective risk factors for PIG and how gender, school type, and age influence these relationships. METHODS Adolescents (grades 5-13; N = 4,390) answered two surveys one year apart which were linked by individual codes. They were classified as "victims" based on the Olweus Bullying Questionnaire-Revised. Changes in PIG (T2-T1) were computed based on nine items reflecting the diagnostic criteria for DSM-5 Internet Gaming Disorder. RESULTS Traditional and cybervictimization independently predicted changes in PIG. The emergence of traditional victimization only, cybervictimization only, and particularly, both forms of victimization simultaneously, was associated with an increase in PIG. A decrease in PIG was only found if victimization terminated in both contexts. Further, an additive effect was found if traditional victimization newly extended to cyberspace. For boys and B-level students, the emergence of traditional victimization was associated with a larger increase in PIG than for girls and A-level students, when compared to the absence of traditional victimization. For boys, this also applied for cybervictimization. DISCUSSION The emergence of bullying victimization in either an offline or online context appears to be a risk factor for PIG. Importantly, victimization must be stopped in both contexts for a decrease in PIG. Therefore, prevention programs need to focus on bullying offline as well as online to counter PIG. Efforts should especially focus on boys and B-level students

Internet sex addiction: a review of empirical research

The advent of the internet has added another medium in which people can engage in sexual behaviour. This ranges from the passive consumption of online pornography to the interactive exchange of sexual content in cybersex chat rooms. It is believed that access, affordability and anonymity are critical factors that make the Internet viable for the acquisition, development and maintenance of online sexuality. For some, sexual behaviours online are fulfilling, whereas for others, they may take on addictive qualities. Internet sex addiction can be conceptualized as the intersection between Internet addiction and sex addiction and the current literature suggests that there does not appear a clear dividing line between these psychopathologies. The aim of this paper was to provide a comprehensive overview of the empirical studies that have investigated Internet sex addiction in adults. Based on these, it was concluded that engaging in sexual behaviours on the Internet can go awry and result in Internet sex addiction, as it can lead to a wide variety of negative consequences for the individuals affected. Particular attention is drawn to the implications for future research in order to establish the pathological status of Internet sex addiction as a sub-form of Internet addiction, that shares characteristics of real life sex addiction, but which is not to be equated with it. Accordingly, the need for a clear diagnostic framework to clinically assess Internet sex addiction is emphasized as the first step towards understanding the potentially psychopathological qualities and repercussions of sexual behaviours on the Internet
