Ranking 2010 in production and research productivity in Spanish public universities

The creation of the European Higher Education Area has brought the relevance of the scientific quality assessment in higher education. The result of this interest is a growing interest in the development of rankings of universities, both nationally and internationally. To continue the line started two years ago, the goal of this research is to update the ranking of research productivity in Spanish public universities with the data of 2010. We follow the same methodology to data from 2008 and 2009; although this year it includes measures of total production. The same indicators to evaluate research in 2009: journals articles indexed in the JCR, research periods, research + development projects, doctoral dissertations, grants for training university teachers, Doctoral Programs with Quality Mention and patents. From the results obtained show that universities with higher production were Complutense de Madrid, Barcelona and Granada. The most productive were the Pompeu Fabra University, the Pablo de Olavide, and the Autonoma de Barcelona.     

The Role of Maternal Depression on Treatment Outcome for Children with Externalizing Behavior Problems

Studies have shown that, on average, Parent Management Training combined with cognitive-behavioral therapy decreases children’s externalizing behavior, but some children do not improve through treatment. The current study aimed to examine the role of maternal depression in understanding this variability in treatment outcome. Children with externalizing behavioral problems and their parents were recruited from combined Parent Management Training and Cognitive-Behavioral programs in “real-world” clinical settings. At pre- and post treatment, maternal depression and children’s externalizing behavior were assessed. Results showed that treatment was less effective for children of depressed mothers compared to non-depressed mothers and that improvements in maternal depression were associated with improvements in children’s externalizing behavior. These findings suggest that treatment programs for children with externalizing problems may be able to improve outcomes if maternal depression is a target of intervention.     

Predicting depressive symptoms among the mothers of children with leukaemia: a caregiver stress model perspective

The aim of this study was to find out the predictors of depressive symptoms of mothers of children with leukaemia. The potential predictors were chosen in the light of the caregiver stress model [Pearlin, Mullan, Semple, and Skaff, 1990. Caregiving and the stress process: An overview of concepts and their measures. The Gerontologist, 30(5), 583-594.], which examines the caregiver stress as composed of many factors such as the background variables, primary and secondary stressors, mediators and psychological health outcomes. This study included the caregiving tasks, basic needs of the caregivers and role strain as the stressors; coping strategies and perceived social support as mediators and depressive symptoms as the outcome variable. The participants of this study were 90 mothers of children with leukaemia. The results revealed that the satisfaction level of the basic needs and role strain were the predictors of the depressive symptoms. While emotion-focussed coping and perceived social support mediated the stressors and the depressive symptoms relationship, problem-focussed coping did not. The possible explanations of the results were explored and the implications were discussed.     

Distinct and shared cognitive functions mediate event- and time-based prospective memory impairment in normal ageing

Prospective memory (PM) is the ability to remember to perform an action at a specific point in the future. Regarded as multidimensional, PM involves several cognitive functions that are known to be impaired in normal ageing. In the present study we set out to investigate the cognitive correlates of PM impairment in normal ageing. Manipulating cognitive load, we assessed event- and time-based PM, as well as several cognitive functions, including executive functions, working memory, and retrospective episodic memory, in healthy participants covering the entire adulthood. We found that normal ageing was characterised by PM decline in all conditions and that event-based PM was more sensitive to the effects of ageing than time-based PM. Whatever the conditions, PM was linked to inhibition and processing speed. However, while event-based PM was mainly mediated by binding and retrospective memory processes, time-based PM was mainly related to inhibition. The only distinction between high- and low-load PM cognitive correlates lies in an additional, but marginal, correlation between updating and the high-load PM condition. The association of distinct cognitive functions, as well as shared mechanisms with event- and time-based PM, confirm that each type of PM relies on a different set of processes.     

How Accurate are Recruiters' First Impressions of Applicants in Employment Interviews?

The ability of recruiters and laypersons (students) to detect applicant personality traits and deception was studied. Participants viewed mock videotapes of target applicants answering interview questions. They subsequently judged the applicants' personality on the Big Five dimensions. Then, they viewed another videotape with other applicants presenting themselves either truthfully or not, and subsequently guessed which version was truthful. Personality judgments were compared with targets' self‐assessments and peer assessments to create an accuracy score. Both recruiters and students accurately detected applicants' global personality profile. Recruiters were better at this than students. However, students were better at judging the specific traits of openness, extraversion, and conscientiousness, whereas recruiters only accurately detected openness. Recruiters detected lies above chance whereas students did not.     

Conscious and unconscious reward cues can affect a critical component of executive control

The present study investigates whether updating an important function of executive control can be driven by unconscious reward cues. Participants had to memorize several numbers and update those numbers independently according to a sequence of arithmetic operations. At the beginning of each trial, a reward (1 euro or 5 cents) was presented, either subliminally or supraliminally. Participants could earn the reward if they found the correct response on the updating task. Results showed better performance when a high (conscious or unconscious) reward was at stake compared to a low reward. This suggests that subliminal information can influence a component process of executive control traditionally thought to require consciousness.     

Statistical Significance of the Contribution of Variables to the PCA solution: An Alternative Permutation Strategy

In this paper, the statistical significance of the contribution of variables to the principal components in principal components analysis (PCA) is assessed nonparametrically by the use of permutation tests. We compare a new strategy to a strategy used in previous research consisting of permuting the columns (variables) of a data matrix independently and concurrently, thus destroying the entire correlational structure of the data. This strategy is considered appropriate for assessing the significance of the PCA solution as a whole, but is not suitable for assessing the significance of the contribution of single variables. Alternatively, we propose a strategy involving permutation of one variable at a time, while keeping the other variables fixed. We compare the two approaches in a simulation study, considering proportions of Type I and Type II error. We use two corrections for multiple testing: the Bonferroni correction and controlling the False Discovery Rate (FDR). To assess the significance of the variance accounted for by the variables, permuting one variable at a time, combined with FDR correction, yields the most favorable results. This optimal strategy is applied to an empirical data set, and results are compared with bootstrap confidence intervals.     

The influence of prior knowledge on the retrieval‐directed function of note taking in prior knowledge activation

Background. Prior knowledge activation facilitates learning. Note taking during prior knowledge activation (i.e., note taking directed at retrieving information from memory) might facilitate the activation process by enabling learners to build an external representation of their prior knowledge. However, taking notes might be less effective in supporting prior knowledge activation if available prior knowledge is limited. Aims. This study investigates the effects of the retrieval‐directed function of note taking depending on learners' level of prior knowledge. It is hypothesized that the effectiveness of note taking is influenced by the amount of prior knowledge learners already possess. Sample. Sixty‐one high school students participated in this study. A prior knowledge test was used to ascertain differences in level of prior knowledge and assign participants to a low or a high prior knowledge group. Method. A 2×2 factorial design was used to investigate the effects of note taking during prior knowledge activation (yes, no) depending on learners' level of prior knowledge (low, high) on mental effort, performance, and mental efficiency. Results. Note taking during prior knowledge activation lowered mental effort and increased mental efficiency for high prior knowledge learners. For low prior knowledge learners, note taking had the opposite effect on mental effort and mental efficiency. Conclusions. The effects of the retrieval‐directed function of note taking are influenced by learners' level of prior knowledge. Learners with high prior knowledge benefit from taking notes while activating prior knowledge, whereas note taking has no beneficial effects for learners with limited prior knowledge.     

Duration discrimination by musicians and nonmusicians

This study investigated the effects of stimulus modality, standard duration, sex, and laterality in duration discrimination by musicians and nonmusicians. Seventeen musicians (M age = 24.1 yr.) and 22 nonmusicians (M age = 26.8 yr.) participated. Auditory (1,000 Hz) and tactile (250 Hz) sinusoidal suprathreshold stimuli with varying durations were used. The standard durations tested were 0.5 and 3.0 sec. Participants discriminated comparison stimuli which had durations slightly longer and shorter than the standard durations. Difference limens were found by the method of limits and converted to Weber fractions based on the standard durations. Musicians had lower, i.e., better, Weber fractions than nonmusicians in the auditory modality, but there was no significant difference between musicians and nonmusicians in the tactile modality. Auditory discrimination was better than tactile discrimination. Discrimination improved when the standard duration was increased both for musicians and nonmusicians. These results support previous findings of superior auditory processing by musicians. Significant differences between discrimination in the millisecond and second ranges may be due to a deviation from Weber's law and the discontinuity of timing in different duration ranges reported in the literature.
