Copyright @ 2010 Elsevier B.V.In ancestral human environments, muscularity and height (in males) and physical attractiveness (in both sexes) would theoretically have correlated positively with one’s social status, and thus with one’s ability to benefit from social inequality. We therefore hypothesized that individuals who are more characterized by these traits would be less egalitarian (i.e., less likely to believe that resources should be distributed equally in social groups). We used a white-light 3D body scanner to extract anthropometric measurements from 118 participants, and our four egalitarianism measures included social dominance orientation and social value orientation. We found that as hypothesized, muscularity and waist–chest ratio in males, and self-perceived attractiveness in both sexes, tended to associate significantly in the predicted directions with the four egalitarianism measures; most of these correlations were of medium size. Neither height, nor two anthropometrically-assessed attractiveness measures (volume height index and waist–hip ratio), associated significantly with any egalitarianism measure in either sex. Egalitarianism has crucial social repercussions (e.g., taxes, welfare and civil rights), and results from the current study shed light on its origins

When Models Interact with their Subjects: The Dynamics of Model Aware Systems

A scientific model need not be a passive and static descriptor of its subject. If the subject is affected by the model, the model must be updated to explain its affected subject. In this study, two models regarding the dynamics of model aware systems are presented. The first explores the behavior of "prediction seeking" (PSP) and "prediction avoiding" (PAP) populations under the influence of a model that describes them. The second explores the publishing behavior of a group of experimentalists coupled to a model by means of confirmation bias. It is found that model aware systems can exhibit convergent random or oscillatory behavior and display universal 1/f noise. A numerical simulation of the physical experimentalists is compared with actual publications of neutron life time and {\Lambda} mass measurements and is in good quantitative agreement.Comment: Accepted for publication in PLoS-ON

The Ethical Dilemma of Information Asymmetry in Innovation: Reputation, Investors and Noise in the Innovation Channel.

A sufficient and steady stream of innovations is widely seen as a basis for healthy modern economies. Governments divert substantial resources from other purposes in society to increase innovation. Yet the failure rate among innovative SMEs is high, suggesting that resources are wasted. Avoiding such waste is a challenge for both governments and investors, but also raises a question for the innovative company, namely how to build and fund the\ud enterprise on an ethical basis. The dilemma of giving in to temptations to ‘cut corners’ clearly exists, for example to exploit the inevitable asymmetry of information arising in innovation and potentially deploy this in support of misleading claims about specific capabilities and/or the unjustified creation and exploitation of reputation. This is consistent with Olaf Fisscher’s finding that entrepreneurs starting new ventures tend to exhibit an inherent bias towards compromising their own values in order to succeed at any cost. When the innoSME’s aspirations are unrealistic or the proposed innovations are of marginal value, the ethical issues are broader and extend also to those who are potential financiers. Noting this as a gap in the ethics literature, we argue that the current situation fails to match economic and ethical ideals and that work is needed to develop tools which allow those who provide finance and support for innovation to target it more effectively at those who have a prospect of successfully launching genuine innovations and thus reduce the ‘noise’ in the innovation field

Studying the Neurobiology of Social Interaction with Transcranial Direct Current Stimulation—The Example of Punishing Unfairness

Studying social behavior often requires the simultaneous interaction of many subjects. As yet, however, no painless, noninvasive brain stimulation tool existed that allowed the simultaneous affection of brain processes in many interacting subjects. Here we show that transcranial direct current stimulation (tDCS) can overcome these limits. We apply right prefrontal cathodal tDCS and show that subjects' propensity to punish unfair behavior is reduced significantl

Referendum Campaigns in the Digital Age: Towards (More) Comparative Analyses in Hybrid Media Systems

Referendum campaigns, which happen in many countries on the national or sub-national level, are highly important and special periods of political communication. Unlike elections, however, referendum campaigns are understudied phenomena. This thematic issue addresses patterns of referendum campaigns, which increasingly take place in digital and hybrid media environments, where political actors conduct campaigns through various channels, news media react to and shape debates on social media, and citizens receive a large share of political information from traditional and digital media. In this editorial, we provide a short overview of how research on referendum campaigns has evolved and how it has started to shift its attention away from news coverage and toward the role of campaign actors and the citizens who use (or engage with) search engines and social media platforms. The articles in this thematic issue reflect this shift but also show that news media remain important actors in referendum campaigns. Finally, we outline further research steps, which should include even more holistic analyses of the hybridity of referendum campaigns and hopefully more comparisons across cases

Effects of dopamine D2/D3 receptor antagonism on human planning and spatial working memory

Psychopharmacological studies in humans suggest important roles for dopamine (DA) D2 receptors in human executive functions, such as cognitive planning and spatial working memory (SWM). However, studies that investigate an impairment of such functions using the selective DA D2/3 receptor antagonist sulpiride have yielded inconsistent results, perhaps because relatively low doses were used. We believe we report for the first time, the effects of a higher (800 mg p.o.) single dose of sulpiride as well as of genetic variation in the DA receptor D2 gene (DA receptor D2 Taq1A polymorphism), on planning and working memory. With 78 healthy male volunteers, we apply a between-groups, placebo-controlled design. We measure outcomes in the difficult versions of the Cambridge Neuropsychological Test Automated Battery One-Touch Stockings of Cambridge and the self-ordered SWM task. Volunteers in the sulpiride group showed significant impairments in planning accuracy and, for the more difficult problems, in SWM. Sulpiride administration speeded response latencies in the planning task on the most difficult problems. Volunteers with at least one copy of the minor allele (A1+) of the DA receptor D2 Taq1A polymorphism showed better SWM capacity, regardless of whether they received sulpiride or placebo. There were no effects on blood pressure, heart rate or subjective sedation. In sum, a higher single dose of sulpiride impairs SWM and executive planning functions, in a manner independent of the DA receptor D2 Taq1A polymorphism.This research work was funded by a Core Award from the Medical Research Council and the Wellcome Trust to the Behavioural and Clinical Neuroscience Institute (MRC Ref G1000183; WT Ref 093875/Z/10/Z).

Personalization of tech corporations: Examining personalized news and the media reputation of Google, Facebook, and Apple in Swiss news media

Tech corporations, such as Google, Facebook, and Apple, have increasingly become the focus of public media attention and are subject to public scrutiny due to their prominence and scandals. Often, the news media reports on the corporations’ chief executive officers and founders as representatives of the corporations to make complex company-related information comprehensible and gain more public attention. The personalization trend in the news media has turned some corporate leaders into celebrities and is linked to tech companies’ media reputations, that is, the evaluations of tech companies in the news media. However, research on personalization in corporate news is rare and conflicting, and whether and how personalization is linked to the media reputations of Big Tech corporations is not yet clear. By focusing on different personalization types, this study investigates the relationship between personalization and the evaluation of tech companies in the news. A quantitative content analysis of media articles ( N = 5234) in Swiss news outlets revealed that the news on tech companies is frequently personalized, and personalized news is more negative and more often related to the social aspects of tech corporations than non-personalized news. Our study indicates that personalization is used as a journalistic style in the news about tech corporations but is most common in negative reporting in which the role of tech corporations in society is critically assessed

Testosterone and Human Behavior: The role of individual and contextual variables

The study of testosterone and aggression originated in experimental studies of animals, showing a direct causal link in some species. Human studies showed an overall weak correlation between testosterone and aggression. A theoretical framework (“the challenge hypothesis”) enabled testosterone-behavior interactions in humans to be framed within a theory that emphasized hormonal responses to competition influencing subsequent aggressive behavior. The short-term administrations of testosterone to young women and to young men showed influences on behavioral and neural processes associated with aggression. Other findings are that testosterone influences aggression in high dominance men, and in those with low cortisol levels; and that testosterone can affect both aggressive and prosocial behavior, within the context of an experimental gam

Editorial: Reconceptualizing public sphere(s) in the digital age? On the role and future of public sphere theory

Theories of the public sphere—or more recently, of plural public spheres—are core elements of communication and media research. A lively and dynamic debate exists about the respective theories, and the approaches employed to do so have diversified in recent years. This special issue of Communication Theory aims to assess the role and future of public sphere(s) theory in digital societies: if, and where, are concepts of the public sphere(s) still useful and needed, which criticisms are (still) valid, which not, which new ones might be necessary, and which concepts need to be developed or elaborated to respond meaningfully to the digital transformation? This editorial introduces the topic of and contributions to the special issue as well as nine theses on the development of public sphere(s) theorizing

Change in News Access, Change in Expectations? How Young Social Media Users in Switzerland Evaluate the Functions and Quality of News

Online media environments have changed the way young people access news. Despite much research on the topic, the expectations of journalistic news by young adults who have turned their back on traditional news media remain unclear. We use a novel multimethod qualitative online study design to investigate the perceived quality, functions, and expectations toward journalistic news of young adults in Switzerland who use social media as their main source for news and rarely consume traditional media. Nineteen young adults between 20 and 25 years of age with different educational levels participated in our study in May 2020. Our results show that even though the participants only occasionally use traditional news media channels, they still consider journalistic news relevant and appreciate quality standards of professional journalism such as actuality and veracity (Swart 2021b). Among the functions of news, the participants highlighted sociability and identification. Exchange and discussion of news are, thus, of high relevance online but also offline. Also, the participants show a high affinity toward news on mobilizing topics, which are of interest to themselves and their peers, and motivate them to engage with news more intensely. According to the participants, news should be attractively prepared, such as with audiovisual formats and easy to understand and integrate into everyday life. The participants also expressed a preference to consume news articles from different media brands within a single platform. Our study outlines a fruitful path for comprehensive qualitative research with innovative online tools
