Social media applications such as Twitter, YouTube and Facebook have attained huge popularity, with more than three billion people and organizations predicted to have a social networking account by 2015. Social media offers a rapid avenue of communication with the public and has potential benefits for communicable disease control and surveillance. However, its application in everyday public health practice raises a number of important issues around confidentiality and autonomy. We report here a case from local level health protection where the (...) friend of an individual with meningococcal septicaemia used a social networking site to notify potential contacts. (shrink)

This paper posits that ethical leadership increases important organizational and individual outcomes by reducing politics in the workplace. Specifically, we propose that perceptions of organizational politics serve as a mechanism through which ethical leadership affects outcomes. We further argue that the modeled relationships are moderated by political skill. By means of data from 136 matched pairs of supervisors and subordinates employed by a state agency in the southern US, we found support for our predictions. Specifically, we found that perceptions of (...) organizational politics fully mediated the relationship between perceptions of ethical leadership and helping and promotability ratings. In addition, political skill was found to moderate the direct and indirect effects. (shrink)

The appeal to expert opinion is an argument form that uses the verdict of an expert to support a position or hypothesis. A previous scheme-based treatment of the argument form is formalized within a Bayesian network that is able to capture the critical aspects of the argument form, including the central considerations of the expert's expertise and trustworthiness. We propose this as an appropriate normative framework for the argument form, enabling the development and testing of quantitative predictions as to how (...) people evaluate this argument, suggesting that such an approach might be beneficial to argumentation research generally. We subsequently present two experiments as an example of the potential for future research in this vein, demonstrating that participants' quantitative ratings of the convincingness of a proposition that has been supported with an appeal to expert opinion were broadly consistent with the predictions of the Bayesian model.

Bayesian probability has recently been proposed as a normative theory of argumentation. In this article, we provide a Bayesian formalisation of the ad Hitlerum argument, as a special case of the ad hominem argument. Across three experiments, we demonstrate that people's evaluation of the argument is sensitive to probabilistic factors deemed relevant on a Bayesian formalisation. Moreover, we provide the first parameter-free quantitative evidence in favour of the Bayesian approach to argumentation. Quantitative Bayesian prescriptions were derived from participants' stated subjective (...) probabilities (Experiments 1 and 2), as well as from frequency information explicitly provided in the experiment (Experiment 3). Participants' stated evaluations of the convincingness of the argument were well matched to these prescriptions. (shrink)

Biologists, historians, lawyers, art historians, and literary critics all voice arguments in the critical dialogue about what constitutes evidence in research and scholarship. They examine not only the constitution and "blurring" of disciplinary boundaries, but also the configuration of the fact-evidence distinctions made in different disciplines and historical moments the relative function of such concepts as "self-evidence," "experience," "test," "testimony," and "textuality" in varied academic discourses and the way "rules of evidence" are themselves products of historical developments. The essays and (...) rejoinders are by Terry Castle, Lorraine Daston, Carlo Ginzburg, Ian Hacking, Mark Kelman, R. C. Lewontin, Pierre Vidal-Naquet, Mary Poovey, Donald Preziosi, Simon Schaffer, Joan W. Scott, Eve Kosofsky Sedgwick, and Barbara Herrnstein Smith. The critical responses are by Lauren Berlant, James Chandler, Jean Comaroff, Arnold I. Davidson, Harry D. harootunian, Elizabeth Helsinger, Thomas C. Holt, Francoise Meltzer, Robert J. Richards, Lawrence Rothfield, Joel Snyder, Cass R. Sunstein, and William Wimsatt. (shrink)

The conventional paradigm for developing new treatments for disease mainly involves either the discovery of new drug targets, or finding new, improved drugs for old targets. However, an ion channel found only in invertebrates offers the potential of a completely new paradigm in which an established drug target can be re‐engineered to serve as a new candidate therapeutic agent. The L‐glutamate‐gated chloride channels (GluCls) of invertebrates are absent from vertebrate genomes, offering the opportunity to introduce this exogenous, inhibitory, L‐glutamate receptor (...) into vertebrate neuronal circuits either as a tool with which to study neural networks, or a candidate therapy. Epileptic seizures can involve L‐glutamate‐induced hyper‐excitation and toxicity. Variant GluCls, with their inhibitory responses to L‐glutamate, when engineered into human neurons, might counter the excitotoxic effects of excess L‐glutamate. In reviewing recent studies on model organisms, it appears that this approach might offer a new paradigm for the development of candidate therapeutics for epilepsy. (shrink)

Following Brunswik (1952), social judgement theorists have long relied on regression models to describe both an individual's judgements and the environment about which such judgements are made. However, social judgement theory is not synonymous with these compensatory, static, structural models. We compared the characterisations of physicians' judgements using a regression model with that of a non-compensatory process model (called fast and frugal). We found that both models fit the data equally well. Both models suggest that physicians use few cues, that (...) they disagree among themselves, and that their stated cue use is discrepant with the models' stated cue use. However, the fast and frugal model is easier to convey to physicians and is also more psychologically plausible. Implications for how social judgement theorists conceptualise the process of vicarious functioning are discussed. (shrink)

The rapid rise of international collaborative science has enabled access to genomic data. In this article, it is argued that to move beyond mapping genomic variation to understanding its role in complex disease aetiology and treatment will require extending data sharing for the purposes of clinical research translation and implementation.

Neotraditional organizations are those that exist to sustain indigenous cultures, practices, and institutions as they compete in modern markets. This study examines how a single mechanism, leader transparency, influences change outcomes in neotraditional organizations. We predict that leader transparency will enhance employee cognition- and affect-based trust toward leadership during times of change, thereby supporting relational dynamics within the organization that enable a smooth transition. We also predict that leader transparency will elevate employee acceptance of new technology during change, thereby enhancing (...) desired functional adjustments within the organization. Finally, we predict that leaders who embrace the indigenous heritage of the firm while implementing change will benefit more from being transparent than leaders who ignore the indigenous heritage of the firm. We find overall support for our predictions. These results enhance our understanding of how leaders of neotraditional organizations can manage change successfully while preserving historical cultures, practices, and institutions. (shrink)

The Science and Religion Forum (SRF) seeks to be the premier organization promoting the discussion between science and religion in the United Kingdom. Each year, the SRF holds a conference tackling a topical issue, and in 2017 focused on mental well‐being, neuroscience, and religion. This article introduces the thematic section which is made up of five papers from that conference. As a new field within the science and religion academy, these articles are both wide‐ranging and detailed. This introductory article locates (...) this section within the academy and argues that its place is not only valid but vital, given the increase of mental health problems and the need for medicine, church, and society to answer this problem and present ways to help.

Simple heuristics and regression models make different assumptions about behaviour. Both the environment and judgment can be described as fast and frugal. We do not know whether humans are successful when being fast and frugal. We must assess both global accuracy and the costs of Type I and II errors. These may be “smart heuristics that make researchers look simple.”.

Passionate readers both, Olivia Langdon and Mark Twain courted through books, spelling out their expectations through literary references as they corresponded during their frequent separations. Surprisingly, in the process Olivia Langdon reveals herself not as a hypochondriacal hysteric, as many twentieth-century critics have portrayed her, but as a thoughtful intellectual, widely read in literature, history and modern science. Not so surprisingly, Samuel Clemens reveals himself as a critic and a sceptic, lampooning Langdon's physics lessons and her literary heroines. He also (...) shows himself as an astute strategist, carefully manipulating Langdon and her parents. At the same time, Clemens's letters exhibit his own conservatism about women's nature and women's roles, while Langdon's show her carefully choosing from her culture's array of possible role models.
