Abstract The political and dramatic intentions behind the use of appeals to the early modern public (on and off stage) have already been examined by Shakespeareans. This article points out the technical workings of such appeals by using two new areas of research on decision-making: the ethnography of public meetings and behavioural economics on how to influence choosers. These theories can illuminate the strategies used by the tribunes in handling the citizens of Coriolanus, by Antony in dealing with the plebeians in Julius Caesar, and by Buckingham and Richard when gathering support from the Londoners in Richard III. Using six common psychological biases (anchor-and-adjust, availability, representativeness, priming, arousal, and group norms), Shakespeare’s politicians prompt their hearers to change their minds: a celebrity warrior is recast as a wily tyrant, an execution as a murder, and a regent as the legitimate king.

Recent Hiv Infection

AbstractBackgroundEarly diagnosis is crucial in securing optimal outcomes in the HIV care cascade. Recent HIV infection (RHI) serves as an indicator of early detection in the course of HIV infection. Surveillance of RHI is important in uncovering at-risk groups in which HIV transmission is ongoing. The study objectives are to estimate the proportion of RHI among persons newly-diagnosed in 2013–2017, and to elucidate epidemiological factors associated with RHI in Singapore.MethodsAs part of the National HIV Molecular Surveillance Programme, residual plasma samples of treatment-naïve HIV-1 positive individuals were tested using the biotinylated peptide-capture enzyme immunoassay with a cutoff of normalized optical density ≤ 0.8 for evidence of RHI. A recent infection testing algorithm was applied for the classification of RHI. We identified risk factors associated with RHI using logistic regression analyses.ResultsA total of 701 newly-diagnosed HIV-infected persons were included in the study. The median age at HIV diagnosis was 38 years (interquartile range, 28–51). The majority were men (94.2%), and sexual route was the predominant mode of HIV transmission (98.3%). Overall, 133/701 (19.0, 95% confidence interval [CI] 16.2–22.0%) were classified as RHI. The proportions of RHI in 2015 (31.1%) and 2017 (31.0%) were significantly higher than in 2014 (11.2%). A significantly higher proportion of men having sex with men (23.4, 95% CI 19.6–27.6%) had RHI compared with heterosexual men (11.1, 95% CI 7.6–15.9%). Independent factors associated with RHI were: age 15–24 years (adjusted odds ratio [aOR] 4.18, 95% CI 1.69–10.31) compared with ≥55 years; HIV diagnosis in 2015 (aOR 2.36, 95% CI 1.25–4.46) and 2017 (aOR 2.52, 95% CI 1.32–4.80) compared with 2013–2014; detection via voluntary testing (aOR 1.91, 95% CI 1.07–3.43) compared with medical care; and self-reported history of HIV test(s) prior to diagnosis (aOR 1.72, 95% CI 1.06–2.81).ConclusionAlthough there appears to be an increasing trend towards early diagnosis, persons with RHI remain a minority in Singapore. The strong associations observed between modifiable behaviors (voluntary testing and HIV testing history) and RHI highlight the importance of increasing the accessibility to HIV testing for at-risk groups.

The Right

The traditional market research paradigm believes that, the more data you measure, the more potential for insight the data will hold. However, this paper takes the counter-intuitive standpoint that ‘less is more’. Drawing on the authors’ familiarity with neuroscience and behavioural economics, as well as five years’ worth of panel behavioural data in three categories and data from 2,769 studies across 1.9 million respondents, the paper argues that, just as it is important to ask the right questions in a survey, it is similarly important to measure ‘just enough’ but not too much information about brands. We show that measuring too much data is unnecessary and can even be detrimental to the richness of your data. Readers should take away practical guidelines for creating shorter, smarter surveys that still maintain the integrity of their data … and perhaps even improve it.

Disease Free

A deterministic model for evaluating the impact of voluntary testing and treatment on the transmission dynamics of tuberculosis is formulated and analyzed. The epidemiological threshold, known as the reproduction number is derived and qualitatively used to investigate the existence and stability of the associated equilibrium of the model system. The disease-free equilibrium is shown to be locally-asymptotically stable when the reproductive number is less than unity, and unstable if this threshold parameter exceeds unity. It is shown, using the Centre Manifold theory, that the model undergoes the phenomenon of backward bifurcation where the stable disease-free equilibrium co-exists with a stable endemic equilibrium when the associated reproduction number is less than unity. The analysis of the reproduction number suggests that voluntary tuberculosis testing and treatment may lead to effective control of tuberculosis. Furthermore, numerical simulations support the fact that an increase voluntary tuberculosis testing and treatment have a positive impact in controlling the spread of tuberculosis in the community.
