Academic goals orientation questionnaire for Colombian nursing students:Validity and reliability study

Background Academic motivation guides students toward the achievement of academic objectives and influences their learning. However, there is little research on this subject in nursing education, and validated instruments are not available in Latin America. Objective To determine the validity and reliability of the Academic Goals Orientation Questionnaire in Colombian nursing students. Design Cross-sectional psychometric study developed in the second semester of 2016. Settings and participants. Undergraduate students in nursing at the National University of Colombia (n = 323). Methods The Academic Goals Orientation Questionnaire was administered electronically. In addition, the variables of age, sex and academic year were collected. An analysis of construct validity was carried out by exploratory and confirmatory factor analysis. The reliability of the questionnaire was studied with Cronbach's alpha. Results The exploratory factor analysis revealed the presence of four factors that explain 53.4% of the total variance and that correspond to the dimensions of the original instrument. The overall reliability was α = 0.714. The confirmatory factor analysis verified a good fit of the model (χ2 = 128, p = .024); its standardized mean square residue (SRMR) was 0.0471; the root mean square error of approximation (RMSEA) was 0.03 (IC95% = 0.011–0.044), and the comparative fit index (CFI) was 0.972. The learning or task goal obtained the highest average score (m = 4.67, 95% CI = 4.629–4.712), and the Work avoidance goal was the worst rated (m = 2.126, 95% CI = 2.055–2.198) by the students. Conclusion The Academic Goal Orientation Questionnaire has an adequate validity and reliability in the Colombian context that allows it to be applied in nursing students. However, it is recommended to expand the study with larger samples and other countries in the same context

Stress compensation by gap monolayers for stacked InAs/GaAs quantum dots solar cells

In this work we report the stacking of 10 and 50 InAs quantum dots layers using 2 monolayers of GaP for stress compensation and a stack period of 18 nm on GaAs (001) substrates. Very good structural and optical quality is found in both samples. Vertical alignment of the dots is observed by transmission electron microscopy suggesting the existence of residual stress around them. Photocurrent measurements show light absorption up to 1.2 μm in the nanostructures together with a reduction in the blue response of the device. As a result of the phosphorus incorporation in the barriers, a very high thermal activation energy (431 meV) has also been obtained for the quantum dot emission

Acerca de una novela institucional universitaria construida entre renglones

Notas críticas al artículo "Los antecedentes del ITESO", publicado en el número 1 de la revista Renglones. La intención de estas notas, además de responder a la invitación que hace la propia revista a discutir sus contenidos, es completar el ciclo de las novelas de origen de las tres universidades más antiguas del Occidente de México. El escrito en cuestión se constituye a partir de la constante alusión y elusión de dos puntos: 1. La colaboración y la relación entre jesuitas, autoridades y alumnos de la Universidad Autónoma de Guadalajara: ¿en qué consistía esa relación-colaboración?, ¿cuáles fueron sus características?, ¿cuándo y por qué empezó su discrepancia? 2. Los intereses corporativos de la Compañía de Jesús: los jesuitas que se integran al proyecto del ITESO ¿no tenían realmente ningún interés corporativo?, ¿realmente, como parece señalar el escrito, son inducidos por los profesionistas e industriales a comprometerse en un proyecto "apresurado" que tienen que asumir por "obediencia" y presiones externas? Al final se incluye la respuesta de los autores del texto aludido.ITESO, A.C

Effects of Dry-Land Training Programs on Swimming Turn Performance: A Systematic Review.

Swimming coaches have prescribed dry-land training programs over the years to improve the overall swimming performance (starts, clean swimming, turns and finish). The main aim of the present systematic review was to examine the effects of dry-land strength and conditioning programs on swimming turns. Four online databases were scrutinised, data were extracted using the Preferred PRISMA guidelines and the PEDro scale was applied. A total of 1259 articles were retrieved from database searches. From the 19 studies which were full-text evaluated, six studies were included in the review process. The review indicated that plyometric, strength, ballistic and core training programs were implemented for improving swimming turn performance. Strength, ballistic and plyometric training focusing on neural enhancement seem to be effective for improving swimming turn performance. The data related to training of the core were not conclusive. Coaches should consider incorporating exercises focusing on improving the neuromuscular factor of the leg-extensor muscles into their daily dry-land training programs. More researches are needed to provide a better understanding of the training methods effects and training organisations for improving swimming turn performance.post-print626 K

Sustained exocytosis after action potential-like stimulation at low frequencies in mouse chromaffin cells depends on a dynamin-dependent fast endocytotic process

Under basal conditions the action potential firing rate of adrenal chromaffin cells is lower than 0.5 Hz. The maintenance of the secretory response at such frequencies requires a continuous replenishment of releasable vesicles. However, the mechanism that allows such vesicle replenishment remains unclear. Here, using membrane capacitance measurements on mouse chromaffin cells, we studied the mechanism of replenishment of a group of vesicles released by a single action potential-like stimulus (APls). The exocytosis triggered by APls (ETAP) represents a fraction (40%) of the immediately releasable pool, a group of vesicles highly coupled to voltage dependent calcium channels. ETAP was replenished with a time constant of 0.73 � 0.11 s, fast enough to maintain synchronous exocytosis at 0.2-0.5 Hz stimulation. Regarding the mechanism involved in rapid ETAP replenishment, we found that it depends on the ready releasable pool; indeed depletion of this vesicle pool significantly delays ETAP replenishment. On the other hand, ETAP replenishment also correlates with a dynamin-dependent fast endocytosis process (τ = 0.53 � 0.01 s). In this regard, disruption of dynamin function markedly inhibits the fast endocytosis and delays ETAP replenishment, but also significantly decreases the synchronous exocytosis during repetitive APls stimulation at low frequencies (0.2 and 0.5 Hz). Considering these findings, we propose a model in where both the transfer of vesicles from ready releasable pool and fast endocytosis allow rapid ETAP replenishment during low stimulation frequencies.Fil: Moya Diaz, José Abelino.

Co-evolutionnary network approach to cultural dynamics controlled by intolerance

Starting from Axelrod's model of cultural dissemination, we introduce a rewiring probability, enabling agents to cut the links with their unfriendly neighbors if their cultural similarity is below a tolerance parameter. For low values of tolerance, rewiring promotes the convergence to a frozen monocultural state. However, intermediate tolerance values prevent rewiring once the network is fragmented, resulting in a multicultural society even for values of initial cultural diversity in which the original Axelrod model reaches globalization
