“…Recently, intensive research based on these empirical data, seen as examples of complex dynamical systems in the physics laboratory, has been performed: this research contributed to quantitative study of social phenomena on Blogs [10,11], Diggs [12], Forums [13], online games [14,15], online social networks MySpace [16], Facebook [17], Twitter [18], online chats [19] and other online communication systems. By using different machine-learning methods of text analysis (a recent review of methods can be found in [20]), one can infer contents that are communicated in the text messages exchanged between users.…”

Collective emotional behavior of users is frequently observed on various Web portals; however, its complexity and the role of emotions in the acting mechanisms are still not thoroughly understood.In this work, using the empirical data and agent-based modeling, a parallel analysis is performed of two archetypal systems-Blogs and Internet-Relayed-Chats-both of which maintain self-organized dynamics but not the same communication rules and time scales. The emphasis is on quantifying the collective emotions by means of fractal analysis of the underlying processes as well as topology of social networks, which arise and co-evolve in these stochastic processes. The results reveal that two distinct mechanisms, which are based on different use of emotions (an emotion is characterized by two components, arousal and valence), are intrinsically associated with two classes of emergent social graphs. Their hallmarks are the evolution of communities in accordance with the excess of the negative emotions on popular Blogs, on one side, and smooth spreading of the Bot's emotional impact over the entire hierarchical network of chats, on the other. Another emphasis of this work is on the understanding of nonextensivity of the emotion dynamics; it was found that, in its own way, each mechanism leads to a reduced phase space of the emotion components when the collective dynamics takes place. That a non-additive entropy describes emotion dynamics, is further confirmed by computing the Entropy 2013, 15 5085 q-generalized Kolmogorov-Sinai entropy rate in the empirical data of chats as well as in the simulations of interacting emotional agents and Bots.

“…However, many condemned Swan as a flawed individual, mother and wife; sanctioned the "public policing of pregnant women"; and reinforced negative attitudes towards pregnant women who smoke. 6 While the malicious nature of many comments directed at Swan may be indicative of the negative and, at times, abusive environment of online forums in general 32 , a coherent public health response could have appealed for more understanding of Swan's struggle with quitting smoking. This response could have provided accurate smoking and health information, and important advice and information to support quitting.…”

Objectives: More than 12% of Australian women who gave birth in 2012 reported smoking during pregnancy. Smoking during pregnancy may be under-reported as a result of negative societal attitudes towards pregnant women who smoke. This study sought to identify the extent and nature of online news readers' reactions to online news stories reporting Australian celebrity Chrissie Swan's admission of smoking while pregnant, and whether any smoking and pregnancy health information was included. Study type:Quantitative media content analysis. Methods:Readers' comments posted online in response to Australian online news stories and blogs reporting that Chrissie Swan had admitted smoking while pregnant were coded for inclusion in one of two categories: (1) opposing the judgement of Swan or (2) supporting the judgement of Swan. These comments were then grouped into seven frames. Comments that reflected the readers' own experiences of smoking during pregnancy and the inclusion of any helpful health information were also assessed. Results:Comments that were critical of the judgement of Swan were most frequently found. Specific health facts and quit smoking advice rarely featured. Common frames were 'against making moral judgement' and 'smoking in pregnancy is wrong or harmful'. Conclusions:The lack of comments addressing the misinformation about smoking and quitting during pregnancy suggests a potential role for public health practitioners in future smoking and pregnancy communication programs. The increase in the number of Australians participating in online communities and blogs provides the opportunity for capacity building and resources to enable a proactive and rapid public health response to media opportunities.

“…The views gathered were from self-selecting individuals who were unlikely to be representative of the Australian population. Further, it has been reported that negative emotions motivate people to express their opinions and the most active people who post online comments are those with negative views on events 40 . It was not clear within the published paper whether commentators were posting more than once 33 .…”

INTRODUCTION To systematically review the evidence regarding the effect of standardized packaging on illicit tobacco use. METHODS Data sources were EMBASE, Web of Knowledge, Scopus, PsycInfo, Medline, and the British Library catalogue, from 01/01/1987 to 28/11/2016. Reference lists of included studies were hand searched for additional papers. Search strategies were based on the terms 'tobacco', 'packaging' and 'illicit'. The search was restricted to English language references. Two reviewers screened titles and abstracts for empirical studies that addressed the topic of standardized packaging and illicit tobacco use. This resulted in 153 full text papers retrieved for screening. Following exclusions, ten papers were included in the review. Two reviewers' extracted data using piloted standardized data extraction forms. Studies were assessed for quality and relevance using CASP. RESULTS There was little homogeneity between included studies, so a narrative synthesis was employed. Of the relevant studies five reported smokers did not intend to or actually purchase further illicit tobacco following standardized packaging, although one suggested a small number of responders to online news felt smokers would be more inclined to purchase illicit tobacco, following standardized packaging. Two studies reported retailers did not intend to or actually increase sales of illicit tobacco following standardized packaging. Finally, two studies reported industry data on illicit tobacco were of poor quality and not supported by independent data. CONCLUSIONS There were few studies examining tobacco standardized packaging and illicit trade, however those available showed no evidence that standardized packaging could lead to increases in illicit trade.
