Finitary Polyadic Algebras from Cylindric Algebras

It is known that every α-dimensional quasi polyadic equality algebra (QPEA _α ) can be considered as an α-dimensional cylindric algebra satisfying the merrygo- round properties . The converse of this proposition fails to be true. It is investigated in the paper how to get algebras in QPEA from algebras in CA. Instead of QPEA the class of the finitary polyadic equality algebras (FPEA) is investigated, this class is definitionally equivalent to QPEA. It is shown, among others, that from every algebra in a β-dimensional algebra can be obtained in QPEA _β where , moreover the algebra obtained is representable in a sense.

Sensitivity of the 16 PF Motivational Distortion Scale to response bias

The shortened versions of the 16 PF (Forms C or D) were given to 227 college students (who took Form D twice), 33 prisoners (who took Forms C and D), and 95 substance abusers (who took Form C twice). All were asked to answer honestly, then retake these tests to appear in a better light. Significant differences in Motivational Distortion scores were found between test and retest in each group.

Phenomenology in Mexico: A historical profile

The paper presents a journey along the history of phenomenology (Husserlian Phenomenology or phenomenology derived from Husserl) in Mexico, dealing mainly with its appropriation in the field of philosophy proper. The survey covers almost the whole century, leaving out only the last years and the present situation. Although all those philosophers who came in touch with phenomenology in a significant way in that period are mentioned here, particular attention is laid upon three figures and their meaning in Mexican philosophical culture: they are Antonio Caso, the first influential thinker and professor to dedicate a book to Husserl's philosophy; José Gaos, who enjoys a well-deserved fame as teacher and translator of phenomenological works, and Jorge Portilla, the author of a most valuable phenomenological essay: Phenomenology of Relajo. Thus, in these three cases, their contributions are explored in a somewhat more detailed way.     

Support for collective action against refugees: The role of national,European, and global identifications,and autochthony beliefs

To understand recent anti-refugee protests in Europe, we examined how different levels of inclusiveness of group identities (national, European, and global) are related to intentions to protest among native Europeans. We focused on the mediating role of autochthony (a belief that the first inhabitants of a territory are more entitled) and the moderating role of threat. Survey data from 11 European countries (N = 1,909) showed that national identification was positively associated with autochthony, and therefore, with the intention to protest against refugees. In contrast, global identification was related to lower protest intentions via lower autochthony. These paths were found only among Europeans who perceived refugees as a threat. European identification was not related to the endorsement of autochthony or to collective action. These findings indicate why and when majority members are willing to participate in collective action against refugees, and underscore the importance of global identification in the acceptance of refugees.     

Value ascriptions: rethinking cognitivism

Effect of Concurrent Visual Feedback Frequency on Postural Control Learning in Adolescents

The purpose was to find better augmented visual feedback frequency (100% or 67%) for learning a balance task in adolescents. Thirty subjects were divided randomly into a control group, and 100% and 67% feedback groups. The three groups performed pretest (3 trials), practice (12 trials), posttest (3 trials) and retention (3 trials, 24 hours later). The reduced feedback group showed lower RMS in the posttest than in the pretest (p = 0.04). The control and reduced feedback groups showed significant lower median frequency in the posttest than in the pretest (p < 0.05). Both feedback groups showed lower values in retention than in the pretest (p < 0.05). Even when the effect of feedback frequency could not be detected in motor learning, 67% of the feedback was recommended for motor adaptation.     

Analysis of categorical moderators in mixed‐effects meta‐analysis: Consequences of using pooled versus separate estimates of the residual between‐studies variances

Subgroup analyses allow us to examine the influence of a categorical moderator on the effect size in meta‐analysis. We conducted a simulation study using a dichotomous moderator, and compared the impact of pooled versus separate estimates of the residual between‐studies variance on the statistical performance of the Q _{B (P)} and Q _{B (S)} tests for subgroup analyses assuming a mixed‐effects model. Our results suggested that similar performance can be expected as long as there are at least 20 studies and these are approximately balanced across categories. Conversely, when subgroups were unbalanced, the practical consequences of having heterogeneous residual between‐studies variances were more evident, with both tests leading to the wrong statistical conclusion more often than in the conditions with balanced subgroups. A pooled estimate should be preferred for most scenarios, unless the residual between‐studies variances are clearly different and there are enough studies in each category to obtain precise separate estimates.     

Adapting the Unique Minds Program: Exploring the Feasibility of a Multiple Family Intervention for Children with Learning Disabilities in the Context of Spain

The Unique Minds Program (Stern, Unique Minds Program, 1999) addresses the socio‐emotional needs of children with learning disabilities (LD) and their families. Children and their parents work together in a multiple family group to learn more about LD and themselves as people with the capacity to solve problems in a collaborative way, including problems in family school relationships. This article reports the cultural adaptation of the program for use in Spain and findings from a feasibility study involving three multiple family groups and a total of 15 children and 15 mothers, using a pre‐post design. This Spanish adaptation of the program is called “Mentes Únicas”. Standardized outcome measures indicated an overall statistically significant decrease in children's self‐rated maladjustment and relationship difficulties by the end of the program. Improvements were endorsed by most mothers, although they were not always recognized by the children's teachers. The program had a high level of acceptability: Mothers and children felt safe, understood, and helped throughout the sessions. The efficacy of the adapted intervention for the context of Spain remains to be tested in a more rigorous study.
