Logical structuralism and Benacerraf’s problem

There are two general questions which many views in the philosophy of mathematics can be seen as addressing: what are mathematical objects, and how do we have knowledge of them? Naturally, the answers given to these questions are linked, since whatever account we give of how we have knowledge of mathematical objects surely has to take into account what sorts of things we claim they are; conversely, whatever account we give of the nature of mathematical objects must be accompanied by a corresponding account of how it is that we acquire knowledge of those objects. The connection between these problems results in what is often called “Benacerraf’s Problem”, which is a dilemma that many philosophical views about mathematical objects face. It will be my goal here to present a view, attributed to Richard Dedekind, which approaches the initial questions in a different way than many other philosophical views do, and in doing so, avoids the dilemma given by Benacerraf’s problem.     

Attention to faces modulates early face processing during low but not high face discriminability

In the present study, we investigated whether attention to faces results in sensory gain modulation. Participants were cued to attend either to faces or to scenes in superimposed face—scene images for which face discriminability was manipulated parametrically. The face-sensitive N170 event-related potential component was used as a measure of early face processing. Attention to faces modulated N170 amplitude, but only when faces were not highly discriminable. Additionally, directing attention to faces modulated later processing (~230—300 msec) for all discriminability levels. These results demonstrate that attention to faces can modulate perceptual processing of faces at multiple stages of processing, including early sensory levels. Critically, the early attentional benefit is present only when the “face signal” (i.e., the perceptual quality of the face) in the environment is suboptimal.     

Dynamic epistemic logic with branching temporal structures

van Bentham et al. (Merging frameworks for interaction: DEL and ETL, 2007) provides a framework for generating the models of Epistemic Temporal Logic (ETL: Fagin et al., Reasoning about knowledge, 1995; Parikh and Ramanujam, Journal of Logic, Language, and Information, 2003) from the models of Dynamic Epistemic Logic (DEL: Baltag et al., in: Gilboa (ed.) Tark 1998, 1998; Gerbrandy, Bisimulations on Planet Kripke, 1999). We consider the logic TDEL on the merged semantic framework, and its extension with the labeled past-operator “P _ϵ” (“The event ϵ has happened before which. . .”). To axiomatize the extension, we introduce a method for transforming a given model into a normal form in a suitable sense. These logics suggest further applications of DEL in the theory of agency, the theory of learning, etc.     

Five Years, Twelve Steps, and REBT in the Treatment of Dual Diagnosis

A five-year NIDA-funded grant is described that compared client-centered 12-step-oriented and REBT/SMART Recovery-oriented intensive outpatient treatment/partial hospitalization programs with severely impaired clients with dual diagnosis (serious mental illness/substance abuse). Results are presented and suggestions made for applying the findings.

Nature et significations des échanges entre domaines de vie : l’exemple des nouveaux cadres de l’Action Sociale

Accessing to a management position for the first time implies, for professionals, reflecting on their commitments in different fields and times of their socialization, on their articulation, and on their compatibilities. Referring to the model of an active socialization – active because plural and then conflicting – which rejects a dichotomous approach of the “work/non work” relations, the meaning people give to the relations between their different life spheres, communicating with others, orientates the organization of exchanges between life domains. Content analysis of interviews conducted with new social work managers brought us to distinguish six types of exchanges: temporal, informational, relational, emotional, axiological, ideological and symbolic.     

Can Students be Too Happy in School? The Optimal Level of School Satisfaction

Research to date has assumed linearity in the relationships been school satisfaction (SS), with more positive presumed outcomes associated with increasing levels of school satisfaction (cf. Huebner & Gilman, 2006). Given recent concerns over possible negative consequences associated with the very highest levels of general subjective well-being (Oishi, Diener, & Lucas, 2007), this study investigated the relationships of very high levels of SS, in particular, to measures of academic achievement and interpersonal relationships among middle school students. Analyses based on those of Oishi et al. demonstrated that for both academic achievement and interpersonal relationship measures, the non-linear effect was not significant for this sample of US middle school students. Limitations of the study as well as implications for future research are discussed.     

Gender Differences in the Relations among Patriarchal Beliefs,Parenting, and Teen Relationship Violence in Mexican Adolescents

Teen relationship violence is a global phenomenon associated with adverse outcomes. As in other countries, teen relationship violence is of concern in Mexico. However, few studies have examined the risk and protective factors of teen relationship violence among Mexican adolescents. This study examined whether patriarchal beliefs and exposure to authoritarian parenting among Mexican adolescents are associated with perpetration and victimization of physical and verbal-emotional teen relationship violence. Two hundred and four students (15–18 years old) from Monterrey, Mexico, completed questionnaires. Hierarchical regression analyses controlling for age revealed that among girls, authoritarian parenting was associated with physical and verbal-emotional victimization and verbal-emotional violence perpetration. Among boys, higher endorsement of patriarchal beliefs was associated with lower reports of physical perpetration and physical victimization.
