The Quasi-lattice of Indiscernible Elements

The literature on quantum logic emphasizes that the algebraic structures involved with orthodox quantum mechanics are non distributive. In this paper we develop a particular algebraic structure, the quasi-lattice ( \mathfrakI{\mathfrak{I}}-lattice), which can be modeled by an algebraic structure built in quasi-set theory \mathfrakQ{\mathfrak{Q}} . This structure is non distributive and involve indiscernible elements. Thus we show that in taking into account indiscernibility as a primitive concept, the quasi-lattice that ‘naturally’ arises is non distributive.     

A Meta-analytic Review of the Role of Child Anxiety Sensitivity in Child Anxiety

Conflicting findings exist regarding (1) whether anxiety sensitivity (AS) is a construct distinct from anxiety in children and (2) the specific nature of the role of AS in child anxiety. This study uses meta-analytic techniques to (1) determine whether youth (ages 6–18 years) have been reported to experience AS, (2) examine whether AS differentiates anxiety disordered youth from youth without diagnoses, and (3) ascertain whether AS distinguishes youth with panic disorder from those with other anxiety disorders. The weighted mean effect size analyses included 15 studies and 6,579 participants. Results suggested positive correlational relationships between AS and anxiety for children (r = 0.26) and adolescents (r = 0.36) and higher levels of AS for anxiety disordered youth than non-clinical youth (d = 0.64). Findings tentatively suggested higher levels of AS for youth with panic disorder than youth diagnosed with other anxiety disorders. Implications and future directions in the research of child AS are discussed.     

Interpersonal coordination and ball dynamics in futsal (indoor football)

Here, we report an investigation of the patterned movement behavior of players for a specific sub-phase of the game of futsal, namely when the goalkeeper for the attacking team is substituted with an extra outfield player. The movement trajectories of the ball and players were recorded in both lateral and longitudinal directions and investigated using relative phase analysis. Some differences in phase relations between different playing dyads were noted, indicating specificity of phase attractions, or otherwise, for certain players. In general terms, the defenders demonstrated strong in-phase attractions with the ball and with each other, whereas weaker phase attractions, indicated by increased relative phase variability, were observed for the attackers and ball, as well as between attackers themselves. These results demonstrate different coordination dynamics for the defending and attacking dyads, from which we interpret evidence for different playing sub-systems consistent with different team objectives linked together in an overarching game structure. In keeping with dynamical systems theory for complex systems, we view this sub-phase of futsal as being characterized by coordinated behavior patterns that emerge as a result of self-organizing processes. These dynamic patterns are generated within functional constraints, with players and teams exerting mutual influence on each other.     

If-Clauses and Probability Operators

Adams’ thesis is generally agreed to be linguistically compelling for simple conditionals with factual antecedent and consequent. We propose a derivation of Adams’ thesis from the Lewis-Kratzer analysis of if-clauses as domain restrictors, applied to probability operators. We argue that Lewis’s triviality result may be seen as a result of inexpressibility of the kind familiar in generalized quantifier theory. Some implications of the Lewis-Kratzer analysis are presented concerning the assignment of probabilities to compounds of conditionals.     

Implementation of training programs in self-regulated learning strategies in Moodle format: results of a experience in higher education

This paper tests the efficacy of an intervention program in virtual format intended to train studying and self-regulation strategies in university students. The aim of this intervention is to promote a series of strategies which allow students to manage their learning processes in a more proficient and autonomous way. The program has been developed in Moodle format and hosted by the Virtual Campus of the University of Oviedo. The present study had a semi-experimental design, included an experimental group (n=167) and a control one (n=206), and used pretest and posttest measures (self-regulated learning strategies' declarative knowledge, self-regulated learning macro-strategy planning-execution-assessment, self-regulated learning strategies on text, surface and deep learning approaches, and academic achievement). Data suggest that the students enrolled in the training program, comparing with students in the control group, showed a significant improvement in their declarative knowledge, general and on text use of learning strategies, increased their deep approach to learning, decreased their use of a surface approach and, in what concerns to academic achievement, statistically significant differences have been found in favour of the experimental group.     

Morphological awareness: development trends and patterns of evolution in kindergarten and primary education

We present a study that investigates changes in the acquisition and development of morphological awareness in children from 5 to 7 years old. This investigation was carried out on three separate occasions over two academic years, in which morphological awareness was assessed according to two levels. The data indicate an increase in the morphological awareness development from the kindergarten to primary education, verifying the acquisition in the first instance of the morphological judgment level and secondly, of morphological production level. It also generates a pattern of acquisition of the various parameters that make up morphology.     

Psychometric Properties of the Alabama Parenting Questionnaire-Preschool Revision (APQ-Pr) in 3 Year-Old Spanish Preschoolers

Parenting practices should be assessed and taken into account at an early age, since it is well documented that they are strongly related to children’s development. This study provides data on the psychometric properties of a Spanish version of the Alabama Parenting Questionnaire for Preschool children (APQ-Pr). A community sample of 622 (310 boys and 312 girls) 3 year-old children and their parents, participated in the study. Data were obtained from parents’ reports and correspond to a semi-structured diagnostic interview and self-report questionnaires evaluating parenting and children’s psychological states. Confirmatory factor analysis supported a three-factor solution: positive parenting, inconsistent parenting and punitive parenting. These scales scores showed moderate to good internal consistence (omega values ranged from .54 to .86). Inconsistent parenting scores achieved the strongest associations with external measures of psychopathology, especially for externalizing and conduct problems, as well as for functional impairment, the poorest associations being for the positive parenting scores. Results support the validity of the Spanish APQ-Pr, which is potentially a useful measure for the study of parenting practices regarding preschool children and their relation to conduct problems.     

Evidence-Based Assessment in Children and Adolescents with Obsessive–Compulsive Disorder

The assessment of varied psychiatric disorders, including obsessive–compulsive disorder (OCD), is shifting towards the use of evidence-based assessments (EBAs). This shift has fostered the development, validation and adaptation of several measures to rate obsessive–compulsive symptoms and other related problematic areas such as functional impairment or family attitudes among others. The aim of this paper is to present a systematic review of psychometric studies on pediatric OCD-specific measures to classify these according to assessment evidence-based criteria. Selection criteria that determined which studies were included in the review were: (1) analyzing an OCD measure and (2) including participants’ age being 18 years or younger. The literature search procedure was conducted in Medline, PsycINFO, PsycARTICLES, ERIC, Cochrane Library, and Scholar Google databases and enabled us to locate 42 studies which analyzed psychometric properties of 14 OCD measures studied in children and adolescents. Instruments were grouped into the following assessment areas: symptom presence and severity, functional impairment, family functioning and cognitive dimensions of OCD. Psychometric data regarding internal structure, internal consistency, reliability, validity and diagnostic precision were also reported. Further, measures were classified as well-established, approaching well-established and promising assessments in terms of reliability and validity. We concluded that the assessment of OCD in pediatric populations is a growing field that in a short-medium term could provide a wide variety of EBAs for the evaluation obsessive–compulsive symptoms and other OCD-related dimensions. The paper concludes by highlighting directions for future research.     

Semen Loss and Sexual Anxiety Among Young Unmarried Men: Being Young and Vulnerable in Rural India

Premarital sex remains stigmatized even as the unmarried period of life is lengthening in India. This paper examines how young unmarried men in rural central India conceptualize and understand their sexual health and vulnerability. The data is qualitative, derived from four focus group discussions (N = 38 persons) of young unmarried males that were carried out in conjunction with a larger study on male involvement in reproductive health in the central Indian state of Madhya Pradesh in 2005. Young, unmarried rural men experience a wide range of functional situations which are culturally defined as health problems, such as “weakness,” thought to be caused by masturbation, nocturnal ejaculations, and the loss of semen. Despite constraints on communication on sexuality with married men, young unmarried men largely share with them the culturally hegemonic notion of semen loss as a health hazard. All four discussions pointed to the negative image of psycho-physiological changes related to maturation and further, to the belief that the reproductive functions of men can render them vulnerable and even harm them. Sexual anxiety in young men may in part reflect young men’s socially dependent and insecure life situation and social suffering. Young, unmarried rural men see marriage as the only release from sexual health problems although temporary relief is sought from private health care providers. In the future, men’s unmarried life stage is bound to lengthen in rural India, and consequently sexual health prior to the commencement of active intercourse should receive more attention in public health services and sex education.
