Autoeficacia académica, autorregulación del aprendizaje y rendimiento académico en estudiantes universitarios iniciales
The aim of this research was to determine the relationship between academic self-efficacy, self-regulated learning and academic performance of first-year university students in the Metropolitan Lima area. An assessment was made of 284 students (138 male and 146 female students) admitted to a private university of Lima for the 2013-2 term by using a non-probability and incidental procedure and the General Academic Self-Efficacy Questionnaire, the University Academic Self-Regulated Learning Questionnaire; and for the academic performance of every student, their registered weighted GPA was taken into account. Formulated hypothesis was accepted as correlation coefficients resulting from academic selfefficacy; self-regulated learning and academic performance were both positive and significant, but low. In addition, the correlation between academic selfefficacy and self-regulated learning were positive, significant and moderate.El objetivo del presente estudio fue determinar la relación entre la autoeficacia académica, la autorregulación del aprendizaje con el rendimiento académico en estudiantes universitarios iniciales de Lima Metropolitana. Se evaluó a 284 estudiantes (138 varones y 146 mujeres) ingresantes a una universidad privada de Lima Metropolitana en el período 2013-2, obtenidos a través de un procedimiento no probabilístico, incidental. Se utilizó el Cuestionario de Autoeficacia Académica General, el Cuestionario sobre Autorregulación para el Aprendizaje Académico en la Universidad y para el rendimiento académico se consideró el promedio ponderado consignado en el récord académico de cada estudiante. Se aceptan las hipótesis formuladas debido a que los coeficientes de correlación obtenidos entre la autoeficacia académica, la autorregulación del aprendizaje y el rendimiento académico fueron positivos y significativos en ambos casos, pero bajos. Además la correlación entre la autoeficacia académica y la autorregulación del aprendizaje resultó ser positiva, significativa y moderada.El objetivo del presente estudio fue determinar la relación entre la autoeficacia académica, la autorregulación del aprendizaje con el rendimiento académico en estudiantes universitarios iniciales de Lima Metropolitana.

Temporal reasoning for intuitive specification of context-awareness
One of the most important challenges of the creation of intelligent environments is the specifications of what intelligent behaviours the system will exhibit. The processing of these situations can be computationally demanding. We report on the advances of the specification of a rule-based language which allows for the natural expression of situations of interest as those which occur on Intelligent Environments. The language focuses on quasi real-time situations and includes new temporal operators which allow a natural reference to time instants and to intervals. We explained how the system is implemented and how the system was validated within a Smart Office scenario
Microstrip resonator for microwaves with controllable polarization
In this work the authors implemented a resonator based upon microstrip
cavities that permits the generation of microwaves with arbitrary polarization.
Design, simulation, and implementation of the resonators were performed using
standard printed circuit boards. The electric field distribution was mapped
using a scanning probe cavity perturbation technique. Electron spin resonance
using a standard marker was carried out in order to verify the polarization
control from linear to circular.Comment: 3 pages, 3 figures, submitted to Appl. Phys. Let
Determination of spin polarization in InAs/GaAs self-assembled quantum dots
The spin polarization of electrons trapped in InAs self-assembled quantum dot
ensembles is investigated. A statistical approach for the population of the
spin levels allows one to infer the spin polarization from the measure values
of the addition energies. From the magneto-capacitance spectroscopy data, the
authors found a fully polarized ensemble of electronic spins above 10 T when
and at 2.8 K. Finally, by including the g-tensor
anisotropy the angular dependence of spin polarization with the magnetic field
orientation and strength could be determined.Comment: 3 pages, 2 figures, Accepted Appl. Phys. Let
La relación mente-cerebro: Una propuesta de solución basada en formas de neguentropía intra y extra individuales
It is proposed that the problem of the mind-brain relationship can be overcome by a non-classical materialistic model of personality based on the information defined as a special form of negentropy with a structure and activity, which in five intra-individual categories, organizes all and each of the levels of the personality, and, in an extra-individual category organizes the society. This concept of information leads to a monistic view of the universe and turns into conceptions of society, personality, consciousness, and mental activity based on a theoretical framework that explains the nature of the social individual.Se propone que el problema de la relación mente-cerebro puede ser superado por un modelo materialista, no clásico, de la personalidad, basado en la información definida como una forma especial de neguentropía, con una estructura y una actividad que, en cinco categorías intraindividuales, organiza a todos y cada uno de los niveles de la personalidad, y que, en una categoría extraindividual, organiza a la sociedad. Ese concepto de información conlleva a una visión monista del universo y deviene en concepciones sobre sociedad, personalidad, conciencia y actividad psíquica basadas en un marco teórico que explica la naturaleza del individuo social.Se propone que el problema de la relación mente-cerebro puede ser superado por un modelo materialista, no clásico, de la personalidad, basado en la información definida como una forma especial de neguentropía, con una estructura y una actividad que, en cinco categorías intraindividuales, organiza a todos y cada uno de los niveles de la personalidad, y que, en una categoría extraindividual, organiza a la sociedad.

The 12 prophets dataset
The "Ajeijadinho 3D" project is an initiative supported by the University of
S\~ao Paulo (Museum of Science and Dean of Culture and Extension), which
involves the 3D digitization of art works of Brazilian sculptor Antonio
Francisco Lisboa, better known as Aleijadinho. The project made use of advanced
acquisition and processing of 3D meshes for preservation and dissemination of
the cultural heritage. The dissemination occurs through a Web portal, so that
the population has the opportunity to meet the art works in detail using 3D
visualization and interaction. The portal address is
http://www.aleijadinho3d.icmc.usp.br. The 3D acquisitions were conducted over a
week at the end of July 2013 in the cities of Ouro Preto, MG, Brazil and
Congonhas do Campo, MG, Brazil. The scanning was done with a special equipment
supplied by company Leica Geosystems, which allowed the work to take place at
distances between 10 and 30 meters, defining a non-invasive procedure,
simplified logistics, and without the need for preparation or isolation of the
sites. In Ouro Preto, we digitized the churches of Francisco of Assis, Our Lady
of Carmo, and Our Lady of Mercy; in Congonhas do Campo we scanned the entire
Sanctuary of Bom Jesus de Matosinhos and his 12 prophets. Once scanned, the art
works went through a long process of preparation, which required careful
handling of meshes done by experts from the University of S\~ao Paulo in
partnership with company Imprimate.Comment: Full dataset online at http://aleijadinho3d.icmc.usp.br/data.htm
A survey on the evolution of the notion of context-awareness
The notion of Context has been considered for a long time in different areas of Computer Science. This article considers the use of context-based reasoning from the earlier perspective of AI as well as the newer developments in Ubiquitous Computing. Both communities have been somehow interested in the potential of context-reasoning to support real-time meaningful reactions from systems. We explain how the concept evolved in each of these different approaches. We found initially each of them considered this topic quite independently and separated from each other, however latest developments have started to show signs of cross-fertilization amongst these areas. The aim of our survey is to provide an understanding on the way context and context-reasoning were approached, to show that work in each area is complementary, and to highlight there are positive synergies arising amongst them. The overarching goal of this article is to encourage further and longer-term synergies between those interested in further understanding and using context-based reasoning
