Hume’s theory of justice and Vanderschraaf’s Vulnerablity Objection

In ‘Strategic Justice’, Vanderschraaf argues that many existing theories of justice as mutual advantage, including Hume’s, are not ‘proper accounts of justice’ because they deny the benefits of justice to people who are unable to contribute to the cooperative surplus. Vanderschraaf presents a model in which a practice of giving aid to vulnerable people can be a convention, and argues that this exemplifies justice as mutual advantage. I argue that this convention is not mutually advantageous. According to Hume’s theory, it creates moral obligations of humanity but not of justice

Association of kidney disease measures with risk of renal function worsening in patients with type 1 diabetes

Background: Albuminuria has been classically considered a marker of kidney damage progression in diabetic patients and it is routinely assessed to monitor kidney function. However, the role of a mild GFR reduction on the development of stage 653 CKD has been less explored in type 1 diabetes mellitus (T1DM) patients. Aim of the present study was to evaluate the prognostic role of kidney disease measures, namely albuminuria and reduced GFR, on the development of stage 653 CKD in a large cohort of patients affected by T1DM. Methods: A total of 4284 patients affected by T1DM followed-up at 76 diabetes centers participating to the Italian Association of Clinical Diabetologists (Associazione Medici Diabetologi, AMD) initiative constitutes the study population. Urinary albumin excretion (ACR) and estimated GFR (eGFR) were retrieved and analyzed. The incidence of stage 653 CKD (eGFR < 60 mL/min/1.73 m2) or eGFR reduction > 30% from baseline was evaluated. Results: The mean estimated GFR was 98 \ub1 17 mL/min/1.73m2 and the proportion of patients with albuminuria was 15.3% (n = 654) at baseline. About 8% (n = 337) of patients developed one of the two renal endpoints during the 4-year follow-up period. Age, albuminuria (micro or macro) and baseline eGFR < 90 ml/min/m2 were independent risk factors for stage 653 CKD and renal function worsening. When compared to patients with eGFR > 90 ml/min/1.73m2 and normoalbuminuria, those with albuminuria at baseline had a 1.69 greater risk of reaching stage 3 CKD, while patients with mild eGFR reduction (i.e. eGFR between 90 and 60 mL/min/1.73 m2) show a 3.81 greater risk that rose to 8.24 for those patients with albuminuria and mild eGFR reduction at baseline. Conclusions: Albuminuria and eGFR reduction represent independent risk factors for incident stage 653 CKD in T1DM patients. The simultaneous occurrence of reduced eGFR and albuminuria have a synergistic effect on renal function worsening

Trust Responsiveness. On the Dynamics of Fiduciary Interactions

Trust and trustworthiness are key elements, both at the micro and macro level, in sustaining the working of modern economies and their institutions. However, despite its centrality, trust continues to be considered as a “conceptual bumblebee”, it works in practice but not in theory. In particular, its behavioural rationale still represents a puzzle for traditional rational choice theory and game theory. In this paper “trust responsiveness”, an alternative explanatory principle that can account for trustful and trustworthy behaviour, is proposed. Such principle assumes that people can be motivated to behave trustworthily by trustful actions. The paper discusses the philosophical roots, the historical development, as well as the relational nature of this principle as well as its theoretical implications. © 2010 Elsevie

Empathy, Guilt-Aversion, and Patterns of Reciprocity

This paper reports the results of an experiment aimed at investigating the link between empathy, anticipated guilt, and pro-social behavior. In particular, we test the hypothesis that empathy modulates the anticipatory effect of guilt in bargaining situations and, more specifically, that it correlates with subjects' willingness to give and to repay trust in an investment game. We also control for the effect of individual risk attitude. Our main results show that empathy significantly influences players' pattern of restitution in the investment game and that risk-propensity weakly affects the decision to trust; we also find a significant gender difference in the distribution of empathy. These results seem to indicate that empathy affects pro-social behavior in a more complex way than previously hypothesized by existing models of social preferences.
