Rhétorique et dialectique chez Aristote

Rhetoric and dialectic are two distinct circles, but in intersection. Rhetoric is an application (among others) of the dialectic to public debates. The dialectic is then the intellectual tool of rhetoric, distinct from its emotive means of persuading. But each of them can be antistrophos to the other one because both of them belong to the same sublunar world, our world. Such is Aristotle's answer, both to the sophists and to Plato.

     

Plato's Theory of Punishment and Penal Code in the Laws

I argue that the degree to which a criminal should be punished is determined by three elements: a baseline amount that proportionally compensates the victim and an additional penalty that, first, reforms the criminal and, second, deters others from becoming unjust. My interpretation provides a solution to the interpretive puzzle that has most vexed commentators: the alleged tension between Plato's philosophical theory of punishment and the content of his penal code. I defend a two-step solution to the puzzle. First, on my interpretation, because of the broad role that deterrence must play, this alleged tension is—to a degree—merely apparent. Second, the actual tension can be explained by Plato's commitment to the rule of law, given the epistemic limitations of actual people.     

Cyclists’ handheld phone use and traffic rule knowledge

Phone use is likely to distract cyclists and possibly increase crash risk. Therefore, handheld phone use among cyclists is forbidden by law in some countries, even though cyclists use compensatory strategies to attempt to mitigate distractions and related effects. Both demographic, environmental, and psychological factors have been associated with cyclists’ phone use. This study extends the existing literature by including traffic rule beliefs as an explanatory measure in predicting cyclists’ handheld phone use and additionally explores how well cyclists know these rules in different legislative contexts. Online questionnaire responses were collected in 2019 among 1055 cyclists living in Denmark (N = 568), where handheld phone use for cyclists was forbidden, and in the Netherlands (N = 487), where it was legal. Responses on phone use, traffic rule knowledge, cycling behaviour, demographic, and psychological measures were used to identify factors contributing to the likelihood of handheld phone use in three regression models; one for all respondents and one for each country. In the combined model, believing there are no rules on handheld phone use increased the likelihood of handheld phone use while cycling. Other significant factors were subjective norm, perceived behavioural difficulty, self-identity as a safe cyclist as well as demographic factors. The country-specific models found that male gender was only associated with more handheld phone use in the Netherlands, while believing there was no ban was only connected to an increase in the likelihood of using handheld phone in Denmark. Correct traffic rule knowledge was almost three times higher in Denmark, where handheld phone use was forbidden. The results identify subjective norms, potential overconfidence, and traffic rule awareness (when there is a ban) as relevant factors in reducing the likelihood of cyclists’ handheld phone use. Findings from country-specific models possibly point to a connection between culture and traffic rules. Future research should focus on underlying mechanisms and awareness of traffic rules.     

Association rule learning in neuropsychological data analysis for Alzheimer’s disease

Efficient methods of analysis readily available for clinicians continue to be limited within neuropsychological assessment at the raw data level. Here, a novel approach for generating predictive response patterns and analysing neuropsychological raw data is offered. In order to assess the usefulness of association rule learning as an analysis tool for neuropsychological raw data, Frequent Pattern Growth (FP-Growth) was used to mine patterns from the Consortium to Establish a Registry for Alzheimer’s Disease Neuropsychological Battery (CERAD-NB) database. Complete assessment data for 84 post-mortem confirmed Alzheimer’s disease (AD) cases and 294 age, race, and education matched controls were analysed across baseline and one-year follow-up using FP-Growth, for the purpose of assessing the clinical utility of a finer analysis at the raw data level and the feasibility of predicting response patterns for clinical/control groups. Output from FP-Growth, in terms of the number of frequent itemsets retained across both evaluation timepoints, was discernable between controls, mild, and moderate to severe Alzheimer’s disease cases (p < .001, and η² = .488). Patterns within raw data scores, both in terms of frequent itemsets and predictive association rules, appear to be differentiable across groups within neuropsychological analysis, which indicates that FP-Growth is applicable as a supplementary analysis tool for neuropsychological assessment by means of offering an additional level of data analysis, predictive item response capabilities, and aiding in clinical decision making.     

Integrative and Distributive Negotiation in Small Groups: Effects of Task Structure, Decision Rule, and Social Motive

This study examined the interactive effects of task structure, decision rule, and social motive on small-group negotiation processes and outcomes. Three-person groups negotiated either within an asymmetrical task structure (in which a majority of group members have compatible interests) or within a symmetrical task structure (in which no such majority exists). Groups negotiated either under unanimity rule or under majority rule, and group members were either egoistically or prosocially motivated. Results revealed cumulative main effects and the predicted three-way interaction: Groups in an asymmetrical task structure engaged in more distributive and less integrative behavior, reached lower joint outcomes, and experienced a less positive group climate especially when they had an egoistic rather than prosocial motivation and unanimity rather than majority rule applied. Theoretical implications and avenues for future research are discussed.
