Prediction of Burnout in Volunteers

This work studies the personal experience of volunteering and several antecedent and consequent variables. We studied the effect of the amount of time dedicated to the organization, motivation, social support, integration in the organization, self‐efficacy, and characteristics of the work on a consequent variable of the volunteering experience; that is, burnout, with its 3 components of efficacy, cynicism, and exhaustion. The statistical analysis shows that the time dedicated to volunteering and the extrinsic motivations (i.e., social and career) predicts higher levels of burnout, whereas intrinsic motivations (i.e., values and understanding), life satisfaction, and integration in the organization are negatively related to burnout.

Learning in High-Tech and Multimedia Environments

ABSTRACT— When do high-tech environments promote learning? The goal of this article is to offer one answer to this question by examining the classic distinction between media and method, in terms of their roles in promoting learning with technology. To this end, I first propose a cognitive theory of learning with media, from which a set of instructional design principles are derived. Then I review research in which the relative learning contributions of method and media are investigated, and I offer final reflections for future research.     

Mosaic trisomy 20 and mitigation in capital crimes sentencing: A review and case report

Trisomy 20 is a genetic abnormality in which individuals have an extra copy of chromosome 20. Complete trisomy 20 is rare and believed to be incompatible with life. A mosaic form of trisomy 20, in which only some cells or tissues contain the extra chromosome, is a relatively commonly encountered chromosomal abnormality found during prenatal testing, and c. 90% result in a normal phenotype. However, despite the absence of a consistent phenotype, certain findings have been reported across multiple cases of mosaic trisomy 20. These include an array of morphological findings, developmental delays, and learning disabilities. Beyond physical manifestations, a wide range of developmental and learning delays have also been reported. In this work, we provide an overview of the trisomy 20 literature and a case report of a young adult male with mosaic trisomy 20 who committed homicide. His developmental and life history, eventual diagnosis of mosaic trisomy 20, similarities and differences in his condition compared with prior research findings, and potentially new phenotypic findings associated with trisomy 20 that he manifested (childhood visual hallucinations, self‐injury, polydactyly) are presented. Additionally, the potential role of this genetic diagnosis in his neuropsychiatric history and its successful application as a mitigating factor at his capital sentencing trial are described. We did not identify other similar cases during our search of major scientific and legal databases. As a backdrop, the use of genetics in criminal trials is on the rise, and courts are increasingly likely to accept behavioral genetics evidence; therefore, it is crucial that the legal system is well acquainted with the opportunities and limitations of these approaches.     

Analysis of the conceptual structure of natural and artifactual categories in Alzheimer's disease patients

This work has two goals, the first one is to study in detail the conceptual structure of some natural and artifactual categories, by using multidimensional scaling (MDS). According to our theoretical approximation, conceptual structure is composed of semantic features, and these features have different entities and nature. As an index of relevance in mental representation of semantic categories, we took the frequency of production of semantic features on a free verbal production task. Our second goal was to compare the structure of conceptual representations in two populations, healthy elderly and Alzheimer's disease (AD) patients, assuming that conceptual representation is impaired in this last population. We assume that the impairment in the conceptual representations of AD patients will show, when the disease reaches a determined level, loosing specific features. This impairment will have serious consequences in the whole conceptual structure.     

Nursing Motives for Helping Scale (N-MHS): reliability and validity

This paper presents the Nursing Motives for Helping Scale (N-MHS), an instrument designed for the evaluation of three of the four motives for helping derived from Batson's helping pathway theory. Dimensionality was analyzed by means of principal component analysis (n = 113), followed by confirmatory factor analysis. A 3-factor structure (corresponding to Batson's differentiation among altruistic motivation, reward-seeking motivation, and punishment-avoidance motivation, respectively), with 9 items distributed in three latent variables, revealed an acceptable fit to the data. Alpha values (.60 - .74) showed that internal consistency was acceptable for a newly developed subscale with a small number of items. Convergence validity was evaluated with correlations between N-MHS subscales scores and scores on the Professional Expectations Scale (Garrosa, Moreno-Jiménez, Rodríguez-Carvajal, and Morante, 2005). The three resulting subscales are a promising instrument for the evaluation of three nursing motives for helping that can contribute to reduce the potential risks and to improve the potential benefits both for the nurse and the patient.
