Behavioral training in neurofeedback has proven to be an essential complement to generalize the effects of pharmacological support in subjects who have Attention Deficit with Hyperactivity Disorder (ADHD). The goal is to stimulate cortical activation, especially in disorders that require increasing intervals of attention and capacity of self-regulation and control. Therefore, this investigation attempts to verify the efficacy of neurofeedback compared with Pharmacological support and the combination of both. Participants were classified into four groups: Control group, students with ADHD who did not receive either pharmacological support of neurofeedback (n = 33, 11 girls and 22 boys); neurofeedback group (n = 33, 11 girls and 22 boys); pharmacological support group (n = 34, 15 girls and 19 boys), and combined group (neurofeedback + pharmacological support; n = 31, 11 girls and 20 boys). Participants were assessed at three levels (assessment of symptoms –EDAHassessment of execution –TOVA- and assessment of cortical activation –QEEG-) at two different moments (before treatment initiation and after treatment). The EEG-Spectrum was used for the neurofeedback intervention. The design was an ex-post-facto descriptive with four treatment groups (pharmacological support, neurofeedback, combined) and a control group that did not receive intervention initially. Results indicate that the combined group obtained more benefits and that the neurofeedback group improved to a greater extent in executive control than the pharmacological support group. It is concluded that this kind of training is an excellent alternative to stimulate activation in subjects with ADHD.

While most of the exoplanets have been found orbiting around solar-type stars, low-mass stars have recently been recognized as ideal exo-life laboratory. Currently, stellar activity is one of the limiting factors for the characterization of Earth-twins and for assessing their habitability: understanding the activity of M dwarfs is thus crucial. In this contribution I present the spectroscopic analysis of the quiet early-M dwarfs monitored within the HADES (HArps-n red Dwarf Exoplanet Survey) radial velocity survey. The spectra allow us to analyze simultaneously the Ca ii H&K doublet and the Hydrogen Balmer series, while the intensive follow up gives us a large number of spectra ( 100) for each target. We complement this dataset with ground-based follow-up photometry and archival X-ray data. I present our results on the activity-rotation-stellar parameters and flux-flux relationships, and discuss the correlation of emission fluxes at low activity levels and the evolution timescales of active regions.

This research evidences the impact of Materials Science and Engineering Clubs as an outreach effort to expand the education and training required for a competitive Nanotechnology workforce beyond traditional STEM areas. An engineering perception questionnaire was implemented as a pre-test/post-test to track student perceptions and goals throughout the academic year to identify trends amongst gender and school level groups. Findings (107 students) show a perceived increase in student knowledge and interest for different fields of study, based on pre/post-test responses, with differences amongst gender and school level groups (middle school and high school). Also, significant differences in students’ aspirations for higher education degree were found among school level and gender. Results show that over 20% of participants increased their aspirations to higher education degrees and their interests in pursuing STEM degrees at end of the academic year. Specific findings on engineering perceptions and perceived level of knowledge and interest in science, engineering, materials, and nanotechnology as a result of club participation and student’s educational aspirations, expectations and future study plans are discussed along with implications for future STEM education.

Several studies have found that, after repeated exposure to new words, children form orthographic representations that allow them to read those words faster and more fluently. However, these studies did not take into account variables related to the words. The aim of this study was to investigate the influence of sublexical variables on the formation of orthographic representations of words by Spanish children. The first experiment used pseudo-words of varying syllabic structure and syllabic frequency. The stimuli for the second experiment were formed with or without context-dependent graphemes. We found that formation of orthographic representations was influenced by syllabic structure (easier for words with simple syllabic structure) and the context-dependency of graphemes (easier in the absence of context-dependent graphemes), but not syllabic frequency. These results indicate that the easier it is to read a word, the easier it is to form an orthographic representation of it.

Studies aimed to assess up to what extent farming and transport previous to slaughtering might affect physiology and meat quality in young goat kids are needed, with the ultimate purpose of promoting practices that minimize stress in these animals. In this regard the effects of on-farm management and transport duration on some physiological responses and meat quality parameters in goat kids were assessed. Two farms representing ‘high’ and ‘low’ welfare-friendly management practices were selected. In total, 32 suckling kids were withdrawn from each farm, transported by road for 2 or 6 h, and then slaughtered. Blood samples were collected both on-farm and in the slaughterhouse, and biochemistry, cell counts and haematocrit were determined. After slaughtering, carcass quality parameters were measured. Longissimus dorsi muscle was dissected and pH, colour parameters, water holding capacity and shear force were measured throughout 8-day ageing period. Results indicate that, regardless its duration, transport caused significant effects on some blood parameters suggesting stress in live animals, like glucose, cortisol or creatine kinase. Despite the marked stress status in animals, this condition was not decisively reflected on L. dorsi quality parameters, but some effects were observed regarding fat cover in carcasses and colour parameters. The results suggest that postmortem changes throughout ageing were more decisive in terms of meat quality than stressful management either on-farm or during transport.

Entrepreneurial attitudes of individuals are determined by different variables, some of them related to the cognitive and personality characteristics of the person, and others focused on contextual aspects. The aim of this study is to review the essential dimensions of enterprising personality and develop a test that will permit their thorough assessment. Nine dimensions were identified: achievement motivation, risk taking, innovativeness, autonomy, internal locus of control, external locus of control, stress tolerance, self-efficacy and optimism. For the assessment of these dimensions, 161 items were developed which were applied to a sample of 416 students, 54% male and 46% female (M = 17.89 years old, SD = 3.26). After conducting several qualitative and quantitative analyses, the final test was composed of 127 items with acceptable psychometric properties. Alpha coefficients for the subscales ranged from .81 to .98. The validity evidence relative to the content was provided by experts (V = .71, 95% CI = .56 - .85). Construct validity was assessed using different factorial analyses, obtaining a dimensional structure in accordance with the proposed model of nine interdependent dimensions as well as a global factor that groups these nine dimensions (explained variance = 49.07%; χ2/df = 1.78; GFI= .97; SRMR = .07). Nine out of the 127 items showed Differential Item Functioning as a function of gender (p < .01, R2 >.035). The results obtained are discussed and future lines of research analyzed.

The core objective of the present work is to explore the reasons why workers from different employment sectors join training courses to improve their job. To this end we assessed achievement motivation, locus of control and professional qualifications according to the participants’ employment sector. The final sample consisted of 1460 active Spanish workers from four different employment sectors: services, catering, metal construction, and others. Of the sample, 40.1% were male and 59.9% female, with a mean age of 33.3 years (SD = 9.7). The results show that the new scale developed to assess achievement motivation, locus of control and workers’ qualifications presents adequate psychometric characteristics. Statistically significant differences were found in relation to employment sector. The areas studied showed satisfactory levels of workers’ effort and achievement motivation to perform their jobs, though their attitudes toward the training courses as a basis for improving their employability are varied. Workers in the catering sector had higher levels of external attribution and the lowest interest in training. Those in the service sector had higher levels of achievement motivation and effort at work. Future research should develop a joint program covering the public and private sectors for the modification of these beliefs, attitudes and attributions.

Three 10-mm-long miniscrews commonly employed in orthodontic treatment were compared in four different situations involving diverse thicknesses of cortical bone. The finite element method (FEM) was used in the study, in which a force of 250 g was applied in two directions: perpendicular and parallel to the bone surface. As the parameter under study was the thickness of cortical bone, simulations were performed in four different bone loss situations: 2.5, 2, 1.5 and 1 mm. Our aim was also to quantify the stresses and displacements generated when applying a force of 250 g perpendicular and parallel to the bone surface under the same skeletal conditions. The results reveal similar performance in the three analysed samples, with increased stresses and displacements in the surrounding bone in relation to similar variations in the thickness of cortical bone.

Since 2005, the University of Puerto Rico-Mayagüez (UPRM) has co-facilitated materials science and engineering (MSE) clubs at low-income middle and high schools in Western Puerto Rico to increase awareness and interest in the areas of materials science, nanotechnology, and engineering. In this article, we describe the club activities and share the results of the 2009 end-of-year assessment regarding knowledge, interest, and educational aspirations in MSE, along with differences based on gender, parent education level, and school level. Overall, participants expressed positive opinions about engineering as a career. While students expressed high interest in pursuing university studies in science and engineering, some differences became apparent based on gender, parent education level, and school level. There were also differences between boys and girls in perceived knowledge gains. The results of this assessment provide promising evidence that school-based MSE clubs may help attract underserved students into the MSE pipeline.

27 Creole and 27 Plymouth Rock×Rhode Island Red hens (cross) 47 months old were used to estimate the effect of three diets; commercial diet, corn+alfalfa and homemade diet on egg weight, white, yolk, egg shell, dry matter, protein, fat and ash content of the yolk; lipid fraction and fatty acid profile of the yolk was estimated too. Eggs were collected at 53 weeks of age, 30 eggs per treatment were randomly selected for laboratory analysis. No differences (P>0.05) were found on egg, white, yolk and egg shell weight between genetic groups; inside groups there was a significant effect of diet on yolk weight in both groups. There was no effect of diet and genetic group on yolk composition (P>0.05); however there was a trend of less content of dry matter and more ash with the homemade diet in both groups. There was a group effect (P<0.05) on cholesterol, cholesterol esters and lecithin content; inside groups there was a diet effect (P<0.05) on total lipid content and triglycerides. No differences (P>0.05) between groups were found for the fatty acid profile; inside groups stearic acid was higher (P<0.05) in the yolk of hens fed with no commercial diet and linoleic acid percentage was higher (P<0.05) with corn plus alfalfa diet. Results indicated that corn+alfalfa and homemade diet seem to alter the egg components, yolk lipids and fatty acid profile.

The diversity within 20 rice varieties used as progenitors in Cuban rice breeding programmes was analysed with respect to agro-morphological traits, pedigree and DNA markers. Eleven agro-morphological traits were scored, and phenotypic (Euclidian) distances between the rice varieties were calculated. Sixty random amplified polymorphism DNA (RAPD) and 115 amplified fragment length polymorphism (AFLP) bands served to determine Dice's distance estimates. Cluster analyses were performed based on genetic distance matrices using the unweighted pair-group method of arithmetical means (UPGMA) as the clustering method. This analysis showed five phenotypic, six genealogical, five RAPD and six AFLP diversity groups. Genetic diversity estimates based on RAPD data, but not on AFLP, efficiently represented the genetic parentage and phenotypic diversity between rice varieties. Combined diversity estimates allowed the identification of 11 different genetic pools and permitted a more effective separation of the progenitor set than those obtained solely by phenotypic and genealogical information. The results of this study stress the necessity to diversify rice parental stocks for further breeding purposes.

Some results of the photometry multi-site observations of two δ Scuti stars, V624 Tau and HD 23194, are presented. The observations were carried out in the framework of a STEPHI network in 1999. We collected 343 hours of useful data and detected seven frequencies in V624 Tau and two frequencies in HD 23194.

Giant lymph node hyperplasia (Castleman's disease) is usually reported as a solitary mediastinal tumour, although involvement of other anatomical sites and a multicentric form have been reported. We describe a rare case of Castleman's disease due to its localisation (the left infratemporal fossa) and histology (plasma-cell variant). A brief review of the main clinico-histological characteristics of Castleman's disease is also presented.
