Abstract

Formal logic has often been seen as uniquely placed to analyse mathematical argumentation. While formal logic is certainly necessary for a complete understanding of mathematical practice, it is not sufficient. Important aspects of mathematical reasoning closely resemble patterns of reasoning in non-mathematical domains. Hence the tools developed to understand informal reasoning, collectively known as argumentation theory, are also applicable to much mathematical argumentation. This chapter investigates some of the details of that application. Consideration is given to the many contrasting meanings of the word 'argument'; to some of the specific argumentation-theoretic tools that have been applied to mathematics, notably Toulmin layouts and argumentation schemes; to some of the different ways that argumentation is implicated in mathematical practices; and to the social aspects of mathematical argumentation.If you are present at a game of chess, it will not suffice, for the understanding of the game, to know the rules for moving the pieces. That will only enable you to recognize that each move

Gratitude in Organizations: Psychometric Properties of the Italian Version of the Gratitude Resentment and Appreciation Test–Revised Short (GRAT–RS) in Workers

“…Four models were examined: unidimensional (all items load on a single general factor), correlational (three oblique correlated factors), second order (three factors are regressed onto a second order factor), and bifactor (items are simultaneously regressed on their respective three factors and onto a general factor). Models were analyzed considering different fit indices: the Comparative Fit Index (CFI) [ 64 ] and the Non-Normed Fit Index (NNFI) [ 65 ] (values greater than 0.90 show a good fit; [ 64 ]); the Root Mean Square Error of Approximation (RMSEA) and the Standardized Root Mean Square Residual (SRMR) [ 66 ] (values lower than 0.08 show good fit; [ 67 ]). The reliability of the Italian version of the GRAT–RS was analyzed by calculating the Cronbach alphas.…”

Androgen Receptor and Cardiovascular Disease: A Potential Risk for the Abuse of Supplements Containing Selective Androgen Receptor Modulators

“…It has been suggested that testolone has an acceptable safety profile in a recent cancer study [42], and anecdotal evidence suggests increases in lean muscle mass and strength [1] and decreases in fat mass [43]. In a recent study in mice, however, it has been reported that testolone did not significantly increase skeletal muscle but did increase liver injury biomarkers [44]. This same study mentioned the possibility that RAD140 may act as an agonist for the AR outside of the muscles since RAD 140 supplementation decreased the effects of testosterone on the prostate and seminal vesicles [44].…”

Unperverting the perverse: Sacrificing transgression for normalised acceptance in the BDSM subculture

“…Stigmatised individuals must continually choose what to disclose and what to conceal about their participation in BDSM (Meeker, 2013). Fear of discovery may mean that practitioners become secretive, have pseudonyms and live double lives which can lead to stress, reduced quality of life, dissatisfaction and disengagement from aspects of mainstream society (Brown, 2010;Moser, 1999).…”
