Enantiomorphy through the looking glass: literacy effects on mirror-image discrimination

To examine whether enantiomorphy (i.e., the ability to discriminate lateral mirror images) is influenced by the acquisition of a written system that incorporates mirrored letters (e.g., b and d), unschooled illiterate adults were compared with people reading the Latin alphabet, namely, both schooled literate adults and unschooled adults alphabetized in adulthood. In various sorting and same-different comparison tasks with nonlinguistic materials, illiterate participants displayed some sensitivity to enantiomorphic contrasts but performed far worse than all the other participant groups when the task required paying attention to such contrasts. The difficulties of illiterate participants were more severe with enantiomorphs than with rotations in the plane or shape contrasts. Learning a written system that incorporates enantiomorphic letters thus pushes the beginning reader to break the mirror invariance characteristic of the visual system, and this process generalizes beyond the realm of symbolic characters.

Importance and Explanatory Relevance: The Case of Mathematical Explanations

A way to argue that something (e.g. mathematics, idealizations, moral properties, etc.) plays an explanatory role in science is by linking explanatory relevance with importance in the context of an explanation. The idea is deceptively simple: a part of an explanation is an explanatorily relevant part of that explanation if removing it affects the explanation either by destroying it or by diminishing its explanatory power, i.e. an important part (one that if removed affects the explanation) is an explanatorily relevant part. This can be very useful in many ontological debates. My aim in this paper is twofold. First of all, I will try to assess how this view on explanatory relevance can affect the recent ontological debate in the philosophy of mathematics—as I will argue, contrary to how it may appear at first glance, it does not help very much the mathematical realists. Second of all, I will show that there are big problems with it.     

Assembling the Whale: Parliaments in the Politics of Nature

Abstarct

In the field of science and technology studies (STS), much research has been concerned with politics. Nevertheless STS research tends to disregard the work of conventional political institutions such as parliaments, especially in the politics of nature, which is often seen as delegating ‘nature’ to science. Parliaments work on nature-objects through documents; paperwork is crucial in its procedures for delegating an issue to be further worked upon at other sites, for securing the issue's return and for enabling a decision. This mode of circulating an issue amounts to a central infrastructure for taking nature into account in politics; this infrastructure enables ‘assembling work’ as a specific mode of parliamentary practice. In the late nineteenth century the Norwegian parliament handled a controversy over whaling. New species, questions and publics were entangled with the whale issue through the parliament's work, its tools and procedures. As such, parliament enabled, worked upon and modified the issue. By assembling the whale issue it performed a politics of nature in rich, complex ways. Hence, understanding the specific site where an issue is taken up is necessary in order to grasp its trajectory and to understand how conventional political sites do politics of nature in practice     

Do you get what you pay for? Sales incentives and implications for motivation and changes in turnover intention and work effort

This study investigated relations between pay-for-performance incentives designed to vary in instrumentality (annual pay-for-performance, quarterly pay-for-performance, and base pay level) and employee outcomes (self-reported work effort and turnover intention) in a longitudinal study spanning more than 2 years. After controlling for perceived instrumentality, merit pay increase, and the initial values of the dependent variables, the amount of base pay was positively related to work effort and negatively related to turnover intention, where both relationships were mediated by autonomous motivation. The amounts of quarterly and annual pay-for-performance were both positively related to controlled motivation, but were differently related to the dependent variables due to different relations with autonomous motivation.     

An Institution-Independent Proof of the Robinson Consistency Theorem

We prove an institutional version of A. Robinson’s Consistency Theorem. This result is then appliedto the institution of many-sorted first-order predicate logic and to two of its variations, infinitary and partial, obtaining very general syntactic criteria sufficient for a signature square in order to satisfy the Robinson consistency and Craig interpolation properties.

Childhood disruptive behaviors and family functioning in clinically referred children: Are girls different from boys?

Baseline assessments of 4 to 8-year-old children, 26 girls and 101 boys, referred to outpatient treatment for disruptive behaviors, were examined, focusing on possible differences between the functioning of boys and girls and their families. Child variables included diagnostic information, measures of disruptive behaviors, social competence, and independent observations of child behaviors. A variety of family variables, such as information regarding parenting practices, parental stress, and depression were included. Teacher reports of disruptive behaviors and social competence at school were included. Teacher ratings of child functioning indicated that boys displayed significantly more externalizing behaviors and they were less socially competent than girls. Parents perceived both girls and boys as highly oppositional and aggressive, and generally speaking, differences were few. Nevertheless, the level of stress was higher in girls' than in boys' families, and mothers of girls reported of higher levels of depressive symptoms. Girls and boys did not differ regarding diagnostic status.     

Aggressive driving in Romania: Psychometric properties of the Driving Anger Expression Inventory

The present research verified the psychometric properties of the Driving Anger Expression Inventory (DAX; Deffenbacher, Lynch, Oetting, & Swaim, 2002) on a Romanian sample (n = 262). Exploratory factor analysis revealed a three-factor structure: Verbal and Physical Aggressive Expression (α = .86), Adaptive/Constructive Expression (α = .88) and Using the Vehicle for Aggressive Expression (α = .83). The aggressive forms of expressing anger were summed up in the Total Driving Aggressive Expression Index (α = .90). Confirmatory factor analysis supported the three factors solution, by showing a good fit into a 30 items version of the DAX. All the aggressive forms of anger expression correlated positively with each other and with trait Aggression-Hostility, while the adaptive way of expressing anger correlated negatively with them, thus supporting the convergent validity of the DAX. Age differences were identified, in that younger drivers scored higher in Using the Vehicle for Aggressive Expression scale and in Total Driving Aggressive Expression Index, while older drivers scored higher in Adaptive/Constructive Expression scale. Several directions for future research concerning the DAX are suggested. Overall, our results showed that the Romanian version of the DAX is a valid tool for assessing aggressive driving.
