Questionnaire of executive function for dancers: an ecological approach

There is a current debate about the ecological validity of executive function (EF) tests. Consistent with the verisimilitude approach, this research proposes the ballet executive scale (BES), a self-rating questionnaire that assimilates idiosyncratic executive behaviors of classical dance community. The BES was administrated to 149 adolescents, students of the Cuban Ballet School. Results present a Cronbach's alpha coefficient of .80 and a split-half Spearman-Brown coefficient r (SB) = .81. An exploratory factor analysis describes a bifactorial pattern of EF dimensions, with a self-regulation component, which explains more than 40% of variance, and a Developmental component, which accounts for more than 20% of variance. The questionnaire's total scores fit linear regression models with two external criteria of academic records, confirming concurrent validity. These findings support the hypothesis that the internalization of specific contextual cultural meanings has a mediating influence in the development of EF.     

License to Ill: The Effects of Corporate Social Responsibility and CEO Moral Identity on Corporate Social Irresponsibility

Although managers and researchers have invested considerable effort into understanding corporate social responsibility (CSR), less is known about corporate social irresponsibility (CSiR). Drawing on strategic leadership and moral licensing research, we address this gap by considering the relationship between CSR and CSiR. We predict that prior CSR is positively associated with subsequent CSiR because the moral credits achieved through CSR enable leaders to engage in less ethical stakeholder treatment. Further, we hypothesize that leaders’ moral identity symbolization, or the degree to which being moral is expressed outwardly to the public through actions and behavior, will moderate the CSR–CSiR relationship, such that the relationship will be stronger when CEOs are high on moral identity symbolization rather than low on moral identity symbolization. Through an archival study of 49 Fortune 500 firms, we find support for our hypotheses.     

Perceptual organization and artificial attention for visual landmarks detection

In biological vision systems, attention mechanisms are responsible for selecting the relevant information from the sensed field of view, so that the complete scene can be analyzed using a sequence of rapid eye saccades. In recent years, efforts have been made to imitate such attention behavior in artificial vision systems, because it allows optimizing the computational resources as they can be focused on the processing of a set of selected regions. In the framework of mobile robotics navigation, this work proposes an artificial model where attention is deployed at the level of objects (visual landmarks) and where new processes for estimating bottom-up and top-down (target-based) saliency maps are employed. Bottom-up attention is implemented through a hierarchical process, whose final result is the perceptual grouping of the image content. The hierarchical grouping is applied using a Combinatorial Pyramid that represents each level of the hierarchy by a combinatorial map. The process takes into account both image regions (faces in the map) and edges (arcs in the map). Top-down attention searches for previously detected landmarks, enabling their re-detection when the robot presumes that it is revisiting a known location. Landmarks are described by a combinatorial submap; thus, this search is conducted through an error-tolerant submap isomorphism procedure.     

The mental time line: An analogue of the mental number line in the mapping of life events

A crucial aspect of the human mind is the ability to project the self along the time line to past and future. It has been argued that such self-projection is essential to re-experience past experiences and predict future events. In-depth analysis of a novel paradigm investigating mental time shows that the speed of this “self-projection” in time depends logarithmically on the temporal-distance between an imagined “location” on the time line that participants were asked to imagine and the location of another imagined event from the time line. This logarithmic pattern suggests that events in human cognition are spatially mapped along an imagery mental time line. We argue that the present time-line data are comparable to the spatial mapping of numbers along the mental number line and that such spatial maps are a fundamental basis for cognition.     

Prejudice against Women in Male-congenial Environments: Perceptions of Gender Role Congruity in Leadership

Some authors assert that there is a feminine advantage in leadership, even though female leaders are often targets of prejudice. Our experiment tested how people’s expectations affect this prejudice in different work environments. Participants evaluated a male or a female candidate for a leadership position in an industry that was congruent or incongruent with the candidate’s gender role. Participants showed prejudice against the female candidate, especially when she worked in an industry incongruent with her gender role. Female and older participants showed more prejudice against the female leader than did male and younger participants. These results invoke role congruity theory (Eagly & Karau, Role congruity theory of prejudice toward female leaders. Psychological Review, 109, 573–598, 2002).     

Buridan’s Secular Demarcation of Logic

Philosophia - In his Tractatus de Consequentiis, the 14th century logician John Buridan states a theorem, which reads like a refutation of Aristotelian Syllogistics. Syllogistics in its usual form,...     

Reasons of love: an introduction

One of the main reasons for philosophers to have embraced Humean constructivism rather than Kantian constructivism is a negative one: they believe that in the end Kantian constructivism is an unstable position. Their idea is that the Kantian constructivist can either choose to hold on to the idea of categorical reasons for action but in that case she has to be prepared to commit to (robust) moral realism (which both Humean and Kantian constructivists reject) or alternatively, she might reject (robust) moral realism but in that case she has to give up on the idea of categoricity. The aim of this paper is to defend Kantian constructivism against Humean constructivism and more specifically against recent objections raised by Sharon Street. I will do so by arguing that Kantian constructivism follows from formal, normative commitments that pertain to instrumental reasoning that Humean constructivists like Sharon Street themselves accept. More specifically I will argue that categorical reasons for action follow from applying the principle of instrumental rationality to the first-person perspective of an agent, provided that there are certain necessary means for action in general. From this follows, I will argue, that Humean constructivists should either become Kantian constructivists or that they have to become sceptics about normativity.
