The impact of group efficacy beliefs and transformational leadership on followers’ self-efficacy : a multilevel-longitudinal study

Using Social Cognitive Theory as our theoretical framework, we analyse how beliefs about group efficacy among team members, together with transformational leadership are two group-level constructs (aggregated members’ shared beliefs), which predicts individual members self-efficacy over time. We conducted a three-wave longitudinal study with 456 participants that were randomly distributed in 112 groups working in three simulated creative collective tasks. We computed random coefficient models in a lagged-effects design. Findings were as expected and group efficacy beliefs and group-level transformational leadership were relevant cross-level predictors of individual self-efficacy over time (even after controlling for baseline levels of individual self-efficacy). Results suggested that these group-level factors are relevant cross-level constructs that explain how individual self-efficacy among group members is developed over time

Long range effects on the optical model of 6He around the Coulomb barrier

We present an optical model (OM) analysis of the elastic scattering data of the reactions 6He+27Al and 6He+208Pb at incident energies around the Coulomb barrier. The bare part of the optical potential is constructed microscopically by means of a double folding procedure, using the Sao Paulo prescription without any renormalization. This bare interaction is supplemented with a Coulomb dipole polarization (CDP) potential, which takes into account the effect of the dipole Coulomb interaction. For this CDP potential, we use an analytical formula derived from the semiclassical theory of Coulomb excitation. The rest of the optical potential is parametrized in terms of Woods-Saxon shapes. In the 6He+208Pb case, the analysis confirms the presence of long range components, in agreement with previous works. Four-body Continuum-Discretized Coupled-Channels calculations have been performed in order to better understand the features of the optical potentials found in the OM analysis. This study searches to elucidate some aspects of the optical potential of weakly bound systems, such as the dispersion relation and the long range (attractive and absorptive) mechanisms.Comment: Accepted in Nucl.

Results from the application of new active methodologies for the toxicology subject learning

Con el fin de adaptar la asignatura de Toxicología (tercer curso) a los nuevos planes de estudio europeos del Grado de Farmacia, se han introducido nuevas metodologías activas basadas principalmente en el trabajo personal y en la participación del alumno en el proceso de enseñanza aprendizaje. La introducción de las nuevas metodologías activas tiene como objetivos un aumento de la capacidad de síntesis, análisis y esquematización por parte del alumnado, un aumento de la participación y del trabajo en grupo y la formación en competencias como el manejo de fuentes bibliográficas y la búsqueda de información. El fin último es mejorar la calidad de la docencia aumentando el interés de los alumnos por los conocimientos adquiridos mediante una forma de enseñanza más participativa, dinámica y práctica que además relacione los contenidos teóricos con la práctica en un futuro profesional aportando al alumno una visión más cercana a la realidad. Para incentivar la participación de forma voluntaria por parte del alumno se ha propuesto la realización de una de dos posibles actividades independientes, pero complementarias: 1) preparación de tres temas inéditos en pregrado y 2) resolución de dos problemas (ABP) para lo que tuvieron que aplicar conocimientos adquiridos en clases teóricas. Éstas se realizaron de forma tutorizada y supervisada por los profesores del Área. Además se contó positivamente la asistencia a clases teóricas y a dos conferencias impartidas por expertos en las áreas de Toxicología Forense y de Toxicología Alimentaria. La valoración de la experiencia ha sido positiva ya que se consiguió un aumento de la asistencia a clase y de la participación por parte de los alumnos, todo ello además se vio reflejado en una mejora de las calificaciones obtenidas.In order to adapt the subject of Toxicology to the new curricula in Europe, new active methodologies have introduced. They are mainly based in personal work and student participation in the process of teaching-learning. The introduction of new active methodologies aims to increase the capacity for synthesis, analysis and schematize in our students, as well as to increase its participation and group work and training in skills such as handling and searching bibliographical sources information. The ultimate goal is to improve the quality of teaching by increasing students' interest for knowledge gained through a more participatory form of education, dynamic and practical. In addition, students would be asked to interrelating theory contents with future professional practice by providing students a closer vision to reality. To encourage voluntary participation by the student, it was proposed to perform one of two independent but complementary activities: a) preparation of three new lessons in undergraduate classes; and 2) resolution of two problems (ABP) for what they had to apply theoretical knowledge acquired. These were carried out tutored and supervised by teachers of the area. In addition, attendance to theory classes and to lectures given by experts in the fields of Forensic Toxicology and Food was positively marked. The assessment of the experience was positive because an increase in class attendance and participation by students was achieved, which was also reflected in an improvement in grades

Role of the 4Kscore test as a predictor of reclassification in prostate cancer active surveillance

Background: Management of active surveillance (AS) in low-risk prostate cancer (PCa) patients could be improved with new biomarkers, such as the 4Kscore test. We analyze its ability to predict tumor reclassification by upgrading at the confirmatory biopsy at 6 months. Methods: Observational, prospective, blinded, and non-randomized study, within the Spanish National Registry on AS (AEU/PIEM/2014/0001; NCT02865330) with 181 patients included after initial Bx and inclusion criteria: PSA =10 ng/mL, cT1c-T2a, Grade group 1, =2 cores, and =5 mm/50% length core involved. Central pathological review of initial and confirmatory Bx was performed on all biopsy specimens. Plasma was collected 6 months after initial Bx and just before confirmatory Bx to determine 4Kscore result. In order to predict reclassification defined as Grade group =2, we analyzed 4Kscore, percent free to total (%f/t) PSA ratio, prostate volume, PSA density, family history, body mass index, initial Bx, total cores, initial Bx positive cores, initial Bx % of positive cores, initial Bx maximum cancer core length and initial Bx cancer % involvement. Wilcoxon rank-sum test, non-parametric trend test or Fisher’s exact test, as appropriate established differences between groups of reclassification. Results: A total of 137 patients met inclusion criteria. Eighteen patients (13.1%) were reclassified at confirmatory Bx. The %f/t PSA ratio and 4Kscore showed differences between the groups of reclassification (Yes/No). Using 7.5% as cutoff for the 4Kscore, we found a sensitivity of 89% and a specificity of 29%, with no reclassifications to Grade group 3 for patients with 4Kscore below 7.5% and 2 (6%) missed Grade group 2 reclassified patients. Using this threshold value there is a biopsy reduction of 27%. Additionally, 4Kscore was also associated with changes in tumor volume. Conclusions: Our preliminary findings suggest that the 4Kscore may be a useful tool in the decision-making process to perform a confirmatory Bx in active surveillance management

Mortars Modified with Geothermal Nanosilica Waste: Effect on the Electrochemical Properties of Embedded Steel Rods

Nowadays, it is a common practice the incorporation of industrial wastes as alternative materials to replace ordinary Portland cement in the concrete manufacture. This technological implementation has as main objectives, the enhancement of concretes properties as well as mitigation of durability problem related to the corrosion phenomena; in order to increase the service life of reinforced concrete structures. Therefore, in this research was studied the electrochemical properties of black steel embedded in mortars. Mortars were fabricated using as a partial substitute of cement (0, 10, 20 and 30 wt. %) a geothermal nanosilica waste composed of amorphous nanosilica of ~20ηm and chlorides (0 and 0.4 wt. %). Mortars were subjected to a cure at 20°C (80% of relative humidity) and 60ºC (100% of relative humidity). The corrosion behaviour was periodically monitorized up to 65 days using electrochemical techniques of corrosion potential (Ecorr) and corrosion current density (icorr). Values of current density (icorr) were obtained by linear polarization resistance (LPR) technique applying Stern-Geary relation to Rp values. Electrochemical results were validated by comparing with gravimetric losses. The porosity, pH and loss of the evaporated water were also evaluated in mortars. Results obtained showed that the integrity of reinforcement rods was affected with the increase of GNW at high temperatures as well as the total chlorides content in mortars

Determinants and Differences in Satisfaction with the Inhaler Among Patients with Asthma or COPD

Satisfaction with the inhaler is an important determinant of treatment adherence in patients with asthma and chronic obstructive pulmonary disease (COPD). However, few studies have compared these 2 groups to identify the factors associated with satisfaction with the inhaler. To assess and compare satisfaction with the inhaler in patients with asthma or COPD and to determine the variables associated with high inhaler satisfaction. A multicenter, cross-sectional study of 816 patients (406 with asthma and 410 with COPD) was conducted. Satisfaction was assessed with the Feeling of Satisfaction with Inhaler (FSI-10) questionnaire. All participants completed the Test of Adherence to Inhalers and either the Asthma Control Test (ACT) or the COPD Assessment Test (CAT). Overall, the asthma group was significantly more satisfied with the inhaler (mean [standard deviation] FSI-10 scores: 44.1 [6.5] vs 42.0 [7.7]; P <.001) and more satisfied on most (7 of 10; 70%) items. Patients with asthma were significantly more satisfied with the inhaler regardless of the adherence level or the type of nonadherence pattern. Younger age, good disease control (ACT ≥20 or CAT ≤10), previous inhaler training, and absence of unwitting nonadherence were all independently and significantly associated with high inhaler satisfaction. Age, disease control, and training in inhalation technique all play a more significant role than the specific diagnosis in explaining satisfaction with the device in patients with asthma and COPD. These findings underscore the need to provide better training and more active monitoring of the inhalation technique to improve patient satisfaction, treatment adherence, and clinical outcomes

Spectroscopy of 18^{18}Na: Bridging the two-proton radioactivity of 19^{19}Mg

The unbound nucleus $^{18}$Na, the intermediate nucleus in the two-proton radioactivity of $^{19}$Mg, was studied by the measurement of the resonant elastic scattering reaction $^{17}$Ne(p,$^{17}$Ne)p performed at 4 A.MeV. Spectroscopic properties of the low-lying states were obtained in a R-matrix analysis of the excitation function. Using these new results, we show that the lifetime of the $^{19}$Mg radioactivity can be understood assuming a sequential emission of two protons via low energy tails of $^{18}$Na resonances

The starburst-active galactic nucleus connection in the merger galaxy Mrk 938: An infrared and X-ray view

Mrk 938 is a luminous infrared (IR) galaxy in the local Universe believed to be the remnant of a galaxy merger. It shows a Seyfert 2 nucleus and intense star formation according to optical spectroscopic observations. We have studied this galaxy using new Herschel far-IR imaging data in addition to archival X-ray, UV, optical, near-IR and mid-IR data. Mid- and far-IR data are crucial to characterize the starburst contribution, allowing us to shed new light on its nature and to study the coexistence of active galactic nuclei (AGN) and starburst activity in the local Universe. The decomposition of the mid-IR Spitzer spectrum shows that the AGN bolometric contribution to the mid-IR and total IR luminosity is small [Lbol(AGN)/LIR ? 0.02], which agrees with previous estimations. We have characterized the physical nature of its strong IR emission and constrained it to a relatively compact emitting region of ?2 kpc. It is in this obscured region where most of the current star formation activity is taking place as expected for luminous IR galaxies. We have used Herschel imaging data for the first time to constrain the cold dust emission with unprecedented accuracy. We have fitted the integrated far-IR spectral energy distribution and derived the properties of the dust, obtaining a dust mass of 3 × 107 M . The far-IR is dominated by emission at 35 K, consistent with dust heated by the ongoing star formation activityThanks to F. Schweizer for kindly providing the optical image of Mrk 938, to J. Gallimore for providing the MIPS SED data, and to H. Krimm and W. Baumgartner for the analysis of the BAT ob- servations.
