Nanoethics and the Breaching of Boundaries: A Heuristic for Going from Encouragement to a Fuller Integration of Ethical,Legal and Social Issues and Science

The intersection of ELSI and science forms a complicated nexus yet their integration is an important goal both for society and for the successful advancement of science. In what follows, I present a heuristic that makes boundary identification and crossing an important tool in the discovery of potential areas of ethical, legal, and social concern in science. A dynamic and iterative application of the heuristic can lead towards a fuller integration and appreciation of the concerns of ELSI and of science from both sides of the divide.     

Hardy personality, self-efficacy, and general health in nursing professionals of intensive and emergency services

In this study, the predictive power of hardy personality and generalized self-efficacy on general health perception was investigated in a sample of nursing personnel working in emergency and intensive care services. A cross-sectional retrospective design was used, and the following measurement instruments were applied: a sociodemographic and work questionnaire, Goldberg's GHQ-28 Health Questionnaire, the Baessler and Schwarzer General Self-efficacy Questionnaire, and the Hardy Personality Subscale of Moreno's Nursing Burnout Questionnaire (CDPE). The results revealed a positive and statistically significant relationship between the individual variables of generalized self-efficacy and hardy personality. A canonical correlation analysis carried out on the psychological distress symptoms with self-efficacy and hardy personality as predictor variables, led us to emphasize the relevance of the construct total hardy personality as a predictor and, consequently, as a protective factor against the onset of psychological distress symptoms in the sample of professionals studied. Lastly, the implications of the results for clinical practice are discussed.     

Psychological treatment of physical maltreatment and negligence in children and adolescents: a meta-analysis

The results of a meta-analysis about the efficacy of psychological treatment for children who have suffered physical maltreatment and neglect by their parents or tutors are presented. Sixteen studies that met our selection criteria were included, providing 22 treated groups and 8 control groups. The results showed an absence of clear differences among the diverse treatments, although all of them exhibited a low-to-medium practical significance. The longer they are, the more effective are the treatments and also when neglect was the type of maltreatment suffered by the children. The effect estimates do not seem to be affected by biases. Finally, the clinical implications of the results, as well as those for future research, are discussed.     

The aha effect in groups and other dynamic learning contexts

The aha effect is a memory advantage for initially ambiguous stimuli (e.g., "The notes were sour because the seam split.") that are subsequently resolved ("Bagpipe") over stimuli that are comprehensible from the outset (see P M. Auble, J. J. Franks, & S. A. Soraci, 1979; T. W. Wills, S. A. Soraci, R. A. Chechile, & H. A. Taylor, 2000). The authors examined the influence of learning context on the aha effect by manipulating whether generative tasks were completed in a group setting or alone. In Experiment 1, participants in a group context either discussed difficult aha sentences, or overheard the discussion. In Experiments 2 and 3, lone participants were exposed to the sentences, and either spoke their thoughts aloud or thought silently. Participants in a group context did, as predicted, exhibit the aha global deletion of quotation marks effect. Moreover, in all experiments an aha effect was found for the active, speaking condition only. The authors discuss implications for generative learning and collaborative discourse processes.     

Self regulation processes measurement through self-report methodology

Nowadays the evaluation of self-regulated learning processes is having a critical time due to the problems concerning the assessment instruments. This paper presents the outcomes of a research study having a main goal: evaluate to what extent student's consciousness of his/her own self-regulated learning and study processes (and the involved strategies and activities) has a significant impact on the quality of his/her answers on self-report type instruments. In order to prove this hypothesis an experimental study was designed and built including a pre and a post-test, having no control group, using a sample of 90 college students from different degree courses. The intervention program lasted 45 hours, divided into 8 work sessions of 5 hours each. The developed work included both theoretical and practical tasks dealing with strategies and activities involved in the self-regulated learning and study processes. The results show that the collected data using a self-report instrument is much more significant and accurate after the intervention program has taken place and that the intervention greatly improves the obtained information using these kind of instruments.     

What works for serious juvenile offenders? A systematic review

This study examines the outcomes of best available empirical research regarding the effectiveness of treatment programs implemented in secure corrections to prevent the recidivism of serious (violent and chronic) juvenile offenders (from 12 to 21 years old). In this review 30 experimental and quasi-experimental studies are analyzed, comparing 2831 juveniles in the treatment groups and 3002 youths for the control groups. The global effect size of these 30 studies in terms of standardized mean difference was d = 0.14 in favour of the treatment groups. This size effect, in terms of "r" coefficient reached the value of 0.07, of low magnitude. The cognitive-behavioral methods of treatment were the most effective in decreasing recidivism. These results report that the rehabilitation programs for serious offenders achieve to reduce the general recidivism in comparison with the control juveniles in approximately seven percent.     

A brief scale to assess cognitive impairment in psychiatric patients

The Screen for Cognitive Impairment in Psychiatry(SCIP) is a brief instrument designed to assess cognitive deterioration in patients with psychiatric disorders, for example, schizophrenia. This study presents the first results obtained with the Spanish version of the SCIP in its three parallel forms with a sample of university students, these results being compared with those obtained with the English version. It is concluded that although there are no form effects, and that therefore the different forms can be used without distinction, there are certain practice effects on some of the instrument's sub-scales. There is also a language effect that may be due to sample and/or cultural characteristics. Finally, in both versions intra-class correlation coefficients and factorial structure are very similar.     

Academic goals, cognitive and self-regulatory strategies

In this paper we analyze differences between cognitive (selection, organizational, elaboration and rehearsal) and self-regulatory (planning, monitoring-regulating) strategies depending on academic goals. A total of 447 obligatory secondary education students (55% boys and 44,7% girls) participated in this study. The results indicated that as well as learning goals, other goals (obtain social approval or a good job) are related to the use of strategies and study engagement. Even performance-approach and performance-avoidance goals are significantly related to cognitive and self-regulatory strategies use.     

Estimation of speakers' weight and height from speech: a re-analysis of data from multiple studies by Lass and colleagues

Research on identification of speakers' weight and height from their speech has yielded controversial results. Conclusions from a series of reports conducted by Lass and colleagues must be interpreted with caution because they are based on comparisons of only two types of data, mean of actual values and mean of estimated values. Cohen and others clearly demonstrated that this method of analysis overstated the accuracy of listeners' judgments. Following Van Dommelen's procedure, data from six of Lass's reports were re-analyzed with more appropriate statistics. Results of re-analysis show that (a) listeners are not very efficient guessing the weight or height of speakers, as only 14%, of the estimations correlated significantly with actual values. (b) Judgments are highly consistent under different acoustic conditions, suggesting that listeners follow vocal stereotypes about the body size of speakers, even though these stereotypes are wrong.     

Exclusion performance and learning by exclusion in dogs

Responding by exclusion is a type of emergent repertoire in which an individual chooses an alternative by the apparent exclusion of other available alternatives. In this case it is possible to respond appropriately to an undefined stimulus (one that has not previously acquired discriminative functions) by excluding the defined alternatives. There is evidence of exclusion in humans and nonhuman animals, although learning as an outcome of exclusion does not always occur. This study aimed to investigate exclusion in visual simple discriminations and learning of new simple discriminations resulting from exclusion in four border collies. Subjects were trained to perform simple simultaneous discriminations between pairs of tridimensional objects, and were then tested for exclusion, novelty control and learning of new simple discriminations. All dogs successfully responded by exclusion, choosing an undefined stimulus displayed with an S‐. For three dogs, it was possible to conclude that these previously undefined stimuli acquired S+ functions, documenting learning of new simple discriminations. However, this required up to four exposures to exclusion trials with each pair of stimuli.
