An Analysis of Item Response Theory and Rasch Models Based on the Most Probable Distribution Method

The most probable distribution method is applied to derive the logistic model as the distribution accounting for the maximum number of possible outcomes in a dichotomous test while introducing latent traits and item characteristics as constraints to the system. The item response theory logistic models, with a particular focus on the one-parameter logistic model, or Rasch model, and their properties and assumptions, are discussed for both infinite and finite populations.     

Above Analysis and Amazement: Some Contemporary Muslim Characterizations of ‘Miracle’ and Their Interpretation

This article aims at contributing to the study of miracles on multiple levels. First, it provides an update on current scholarship in contemporary Muslim interpretations of miracles by summarizing and comparing some positions that, despite their originality and/or potential influence on the wider Muslim readership, are not normally taken into account in a number of recent reconstructions of the concept within Islam. Second, it proposes some complementary philosophical interpretations of those positions, interpretations that involve identifying similarities and commonalities among the positions, despite deep differences and explicit mutual oppositions. As well, this article argues that these interpretations have far-reaching consequences for the philosophical debate on miracles within other traditions and cultures; at stake will be the very meaningfulness of engaging in a univocal, overarching, rationalized interpretation of miracles.     

Happy but unhealthy: The relationship between social ties and health in an emerging network

Social connections are essential to health and well‐being. However, when pursing social acceptance, people may sometimes engage in behavior that is detrimental to their health. Using a multi‐time‐point design, we examined whether the structure of an emerging network of students in an academic summer school program correlated with their physical health and mental well‐being. Participants who were more central in the network typically experienced greater symptoms of illness (e.g., cold/flu symptoms), engaged in riskier health behaviors (e.g., binge drinking), and had higher physiological reactivity to a stressor. At the same time, they were happier, felt more efficacious, and perceived less stress in response to a strenuous math task. These outcomes suggest that social ties in an emerging network are associated with better mental well‐being, but also with poorer physical health and health behaviors.

Exclusive and inclusive protest in Europe: Investigating values,support for democracy,and life conditions

Dissatisfaction with the economic situation and perceived governmental inefficacy in regard to the financial crisis has spawned a widespread feeling of political distrust across Europe. This distrust has been translated into protests against institutional authority that aims at either expanding democratic procedures or supporting xenophobic and populist measures. This research uses European Social Survey data to compare exclusive and inclusive protesters with regard to a number of personal and social values, attitudes toward democratic principles, and different life conditions and socio‐economic resources. It also considers contextual factors to investigate how different protesters' profiles are interwoven with socio‐economic conditions. The results of a multilevel latent profile analysis show that exclusive and inclusive protesters, despite sharing similar levels of political distrust, differ with regard to key values and political attitudes, and these differences are related to individual and collective living conditions. We argue that unfavourable living conditions play a non‐negligible role in increasing the probability of easy (i.e., populist) scapegoat political attitudes. Further support for this hypothesis is provided by the cross‐country analysis, which shows that higher levels of exclusive protest are present in countries that were characterized by worse living conditions before the economic crisis.     

Learning by observation and learning by doing in Down and Williams syndromes

New skills may be learned by active experience (experiential learning or learning by doing) or by observation of others’ experience (learning by observation). In general, learning by observation reduces the time and the attempts needed to learn complex actions and behaviors. The present research aimed to compare learning by observation and learning by doing in two clinical populations with different etiology of intellectual disability (ID), as individuals with Down syndrome (DS) and individuals with Williams syndrome (WS), with the hypothesis that specific profiles of learning may be found in each syndrome. To this end, we used a mixture of new and existing data to compare the performances of 24 individuals with DS, 24 individuals with WS and 24 typically developing children on computerized tasks of learning by observation or learning by doing. The main result was that the two groups with ID exhibited distinct patterns of learning by observation. Thus, individuals with DS were impaired in reproducing the previously observed visuo‐motor sequence, while they were as efficient as TD children in the experiential learning task. On the other hand, individuals with WS benefited from the observational training while they were severely impaired in detecting the visuo‐motor sequence in the experiential learning task (when presented first). The present findings reinforce the syndrome‐specific hypothesis and the view of ID as a variety of conditions in which some cognitive functions are more disrupted than others because of the differences in genetic profile and brain morphology and functionality. These findings have important implications for clinicians, who should take into account the genetic etiology of ID in developing learning programs for treatment and education.     

The analyst's awkward gift: balancing recognition of sexuality with parental protectiveness

The author describes the many roles that the analyst is called upon to fulfill in the transference during the course of an analysis. The loving transference is distinguished from the erotic transference and the erotized transference. Repetition is discussed, as is narcissism, especially in the light of clinical situations in which oedipal issues take center stage. Four brief clinical examples are presented.     

Sharing moral values: anticipated ingroup respect as a determinant of adherence to morality-based (but not competence-based) group norms

This research examines how moral values regulate the behavior of individual group members. It argues that group members behave in line with moral group norms because they anticipate receiving ingroup respect when enacting moral values that are shared by ingroup members. Data from two experimental studies offer evidence in support. In Study 1 (N = 82), morality-based (but not competence-based) ingroup norms determined whether members of a low-status group opted for individual versus collective strategies for status improvement. This effect was mediated by anticipated ingroup respect and emerged regardless of whether group norms prescribed collectivistic or individualistic behavior. These effects were replicated in Study 2 (N = 69), where no comparable effect was found as a result of moral norms communicated by a higher status outgroup. This indicates that social identity implications rather than interdependence or more generic concerns about social approval or importance of cooperation drive these effects.
