Post-traumatic stress symptoms in adolescents exposed to an earthquake: Association with self-efficacy,perceived magnitude,and fear

The objective of this study was to evaluate th×e relationship between the magnitude of an earthquake, the fear experienced, the self-efficacy beliefs, and post-traumatic stress symptoms in adolescents. We expected self-efficacy beliefs to predict post-traumatic stress symptoms, and this relation to be mediated by fear. We used data from a longitudinal project on adolescent normative development that was under way at the time of the 2010 earthquake in Chile. Six months before the earthquake, 218 adolescents responded to a self-efficacy beliefs scale; three months after the earthquake they reported the perceived magnitude of the event, the fear they experienced, and their post-traumatic stress symptoms. Results showed that perceived magnitude was not associated with fear or post-traumatic stress symptoms, but self-efficacy beliefs and fear were associated with post-traumatic stress symptoms. The hypothesized role of fear as a mediator in the relation between self-efficacy beliefs and post-traumatic stress symptoms was supported by the data. The results of the study, suggest that preventive interventions aimed to increase awareness of how to face a disaster may not only contribute to save lives but may also increase adolescentś sense of personal efficacy, reducing subsequent emotional reactivity associated with the event.     

A systematic review of sexual satisfaction

The present theoretical study is a systematic review of research publications in which sexual satisfaction was the dependent variable. After conducting a literature search in major electronic databases and following a selection process, we provide a summary of the main findings of 197 scientific papers published between 1979 and 2012. The review revealed the complexity and importance of sexual satisfaction, which was associated with the following variables and factors: a) individual variables such as socio-demographic and psychological characteristics as well as physical and psychological health status; b) variables associated with intimate relationships and sexual response; c) factors related to social support and family relationships; and d) cultural beliefs and values such as religion. In conclusion, we observed that sexual satisfaction is a key factor in individuals’ sexual health and overall well-being. However, despite its importance, there is a lack of theoretical models combining the most important factors to explain sexual satisfaction.     

Psychometric properties of a Spanish version of the Dyadic Adjustment Scale

The Dyadic Adjustment Scale (DAS) is a self-report instrument measuring marital satisfaction, which has been widely used in different cultures. In Spain, there are to date no studies analysing the psychometric properties of the scale in functional and dysfunctional couples, nor performing independent factor analysis of men and women's data. The objective of this study is to determine some psychometric properties of a Spanish DAS version on a sample of 915 participants: 403 who requested couple therapy, and 512 who did not request therapy. Results support the reliability of the instrument for both subsamples. The confirmatory factor analysis showed a four-factor internal structure that corresponds to the one proposed by the author of the original scale. Furthermore, the Spanish DAS has high discriminant power between both subsamples, and presents as a valid and reliable instrument to measure marital quality in Spanish couples who request couple therapy and those who do not request it.     

Interacting plans

The paper explores certain phenomena which arise in stories, conversations, and human activity in general when the plans of two individuals are formed and carried out in an interactive situation. A notation system for representing interacting plans is introduced and applied in the analysis of a small portion of “Hansel and Gretel.” The analysis illustrates how a single actor plan can be modified by the needs of cooperative interaction with others and how cooperative interactive episodes can be transformed and used deceptively by one party in achieving his or her own covert goals.     

Diagnostic models for procedural bugs in basic mathematical skills

A new diagnostic modeling system for automatically synthesizing a deep-structure model of a student's misconceptions or bugs in his basic mathematical skills provides a mechanism for explaining why a student is making a mistake as opposed to simply identifying the mistake. This report is divided into four sections: The first provides examples of the problems that must be handled by a diagnostic model. It then introduces procedural networks as a general framework for representing the knowledge underlying a skill. The challenge in designing this representation is to find one that facilitates the discovery of misconceptions or bugs existing in a particular student's encoding of this knowledge. The second section discusses some of the pedagogical issues that have emerged from the use of diagnostic models within an instructional system. This discussion is framed in the context of a computer-based tutoring/gaming system developed to teach students and student teachers how to diagnose bugs strategically as well as how to provide a better understanding of the underlying structure of arithmetic skills. The third section describes our uses of an executable network as a tool for automatically diagnosing student behavior, for automatically generating “diagnostic” tests, and for judging the diagnostic quality of a given exam. Included in this section is a discussion of the success of this system in diagnosing 1300 school students from a data base of 20.000 test items. The last section discusses future research directions.     

‘It’s Not Just about Faith’: Narratives of Transformation When Moving Out of Islam in the Netherlands and Britain

ABSTRACT

This article investigates the narratives of people with Islamic backgrounds in the Netherlands and Britain who have moved out of Islam. Rather than focusing primarily on ‘leaving faith’ (i.e. a predominantly negative and religiously centred approach), it will present four types of thematic trajectories that consider the broader life-worlds and experiences of the interlocutors. These themes will illustrate the relative weight of the religious voice in trajectories, rather than presupposing the centrality of religion in one’s (former) identity or trajectory. It will thereby display a broader understanding of the interlocutors’ experiences as being in a negative relation to religion alone: not only religious, but also political, social, ethnic and gender boundaries provided the contexts in which people moved out of Islam. The themes (‘religious break’, ‘social break-away’, ‘the entrance’ and ‘unconscious secularization’) will be illustrated by four case studies. A fifth case will be presented to illustrate the potency of the intertwinement of the themes.     

Comparing natural and abstract categories: A case study from computer science

In order to address the issue of whether abstract and concrete objects are categorized similarly, this paper looks at how computer scientists categorize the common concepts of their field. Using the methodology of Rosch, Mervis, Gray, Johnson, and Boyes-Braem (1976) and of Rosch and Mervis (1975) to identify the categorizations used by computer scientists, this study found that the categorization phenomena reported for concrete objects are quite general, operating over a wider range than was previously thought.
