Mudança linguística em português: aspectos sociolinguísticos da neologia

Neste estudo, proponho-me reflectir sobre o conceito de neologismo, com vista a analisar o contributo deste fenómeno para a mudança linguística do português. Discutirei a relevância de alguns dos critérios propostos por Cabré (1993) e pela Rede Panlatina de Terminologia para a identificação do fenómeno neológico, sustentandome na observação de dados linguísticos relacionados com o domínio da aprendizagem electrónica. É meu propósito ponderar as motivações sociolinguísticas da neologia e analisar possíveis implicações deste processo de criação lexical no tecido linguístico português contemporâneo e no contexto educativo do ensino superior.

Undetectable Levels of CSF Amyloid-β Peptide in a Patient with 17β-Hydroxysteroid Dehydrogenase Deficiency

17β-hydroxysteroid dehydrogenase 10 (HSD10) deficiency is a rare X-linked inborn error of isoleucine catabolism. Although this protein has been genetically implicated in Alzheimer's disease pathogenesis, studies of amyloid-β peptide (Aβ) in patients with HSD10 deficiency have not been previously reported. We found, in a severely affected child with HSD10 deficiency, undetectable levels of Aβ in the cerebrospinal fluid, together with low expression of brain-derived neurotrophic factor, α-synuclein, and serotonin metabolites. Confirmation of these findings in other patients would help elucidating mechanisms of synaptic dysfunction in this disease, and highlight the role of Aβ in both early and late periods of life.

Analysis and visualization of energy use for university campus

The reduction of greenhouse gas emissions is one of the big global challenges for the next decades due to its severe impact on the atmosphere that leads to a change in the climate and other environmental factors. One of the main sources of greenhouse gas is energy consumption, therefore a number of initiatives and calls for awareness and sustainability in energy use are issued among different types of institutional and organizations. The European Council adopted in 2007 energy and climate change objectives for 20% improvement until 2020. All European countries are required to use energy with more efficiency. Several steps could be conducted for energy reduction: understanding the buildings behavior through time, revealing the factors that influence the consumption, applying the right measurement for reduction and sustainability, visualizing the hidden connection between our daily habits impacts on the natural world and promoting to more sustainable life. Researchers have suggested that feedback visualization can effectively encourage conservation with energy reduction rate of 18%. Furthermore, researchers have contributed to the identification process of a set of factors which are very likely to influence consumption. Such as occupancy level, occupants behavior, environmental conditions, building thermal envelope, climate zones, etc. Nowadays, the amount of energy consumption at the university campuses are huge and it needs great effort to meet the reduction requested by European Council as well as the cost reduction. Thus, the present study was performed on the university buildings as a use case to: a. Investigate the most dynamic influence factors on energy consumption in campus; b. Implement prediction model for electricity consumption using different techniques, such as the traditional regression way and the alternative machine learning techniques; and c. Assist energy management by providing a real time energy feedback and visualization in campus for more awareness and better decision making. This methodology is implemented to the use case of University Jaume I (UJI), located in Castellon, Spain.

Growth, optical characterization, and laser operation of a stoichiometric crystal KYb(WO4)(2)

We present our recent achievements in the growing and optical characterization of KYb(WO4)2 (hereafter KYbW) crystals and demonstrate laser operation in this stoichiometric material. Single crystals of KYbW with optimal crystalline quality have been grown by the top-seeded-solution growth slow-cooling method. The optical anisotropy of this monoclinic crystal has been characterized, locating the tensor of the optical indicatrix and measuring the dispersion of the principal values of the refractive indices as well as the thermo-optic coefficients. Sellmeier equations have been constructed valid in the visible and near-IR spectral range. Raman scattering has been used to determine the phonon energies of KYbW and a simple physical model is applied for classification of the lattice vibration modes. Spectroscopic studies (absorption and emission measurements at room and low temperature) have been carried out in the spectral region near 1 µm characteristic for the ytterbium transition. Energy positions of the Stark sublevels of the ground and the excited state manifolds have been determined and the vibronic substructure has been identified. The intrinsic lifetime of the upper laser level has been measured taking care to suppress the effect of reabsorption and the intrinsic quantum efficiency has been estimated. Lasing has been demonstrated near 1074 nm with 41% slope efficiency at room temperature using a 0.5 mm thin plate of KYbW. This laser material holds great promise for diode pumped high-power lasers, thin disk and waveguide designs as well as for ultrashort (ps/fs) pulse laser systems.

Magnetism of isolated Mn12 single-molecule magnets detected by magnetic circular dichroism: Observation of spin tunneling with a magneto-optical technique

We report magnetic and magneto-optical measurements of two Mn12 single-molecule magnet derivatives isolated in organic glasses. Field-dependent magnetic circular dichroism (MCD) intensity curves (hysteresis cycles) are found to be essentially identical to superconducting quantum interference device magnetization results and provide experimental evidence for the potential of the optical technique for magnetic characterization. Optical observation of magnetic tunneling has been achieved by studying the decay of the MCD signal at weak applied magnetic field

Programa Helios-Espa??a : Informe final

Analizar y realizar la evaluaci??n global de los proyectos del programa Helios en Espa??a. 10 Instituciones donde se aplicaron proyectos del programa Helios dentro de las tres redes coordinadas por el INSERSO (CERS, ALM II, ALM III). Variables analizadas: nivel de logro de los objetivos en base a las variables resultados, eficiencia y utilidad de los objetivos; cambios producidos en el propio proyecto desde la perspectivas de modificaciones en los objetivos, objetivos suprimidos, estrategias modificadas y cambios imprevistos y no contrastados; transferencia de tecnolog??a de los proyectos; impacto interno y externo de los proyectos; valoraci??n de los proyectos. Se elabor?? un instrumento de an??lisis que recog??a, en base al principio de contraste entre evaluaci??n interna-externa, los datos suministrados por los participantes de los proyectos, los cuales manifestaban sus observaciones y valoraciones. El planteamiento evaluador se gu??a por una minuciosa sistematizaci??n de los an??lisis y una detenida valoraci??n de la relaci??n proyecto-desarrollo-logros. Los objetivos iniciales que alcanzan un mayor nivel son los dirigidos a la prestaci??n directa de servicios tales como formaci??n, adiestramiento de habilidades y valoraciones diagn??sticas; en cambio, los planteados en torno a iniciativas m??s novedosas o complejas de ejecuci??n como la adaptaci??n de transportes o modelos laborales no protegidos, han encontrado grandes dificultades para su consecuci??n. Los proyectos no han modificado apenas los objetivos pero s?? han cambiado ciertas estrategias como resultado de demandas puntuales. Las consecuencias o impactos que los distintos proyectos han conseguido en su entorno pueden considerarse, en general, como no significativas. ??nicamente los procedimientos de rehabilitaci??n de sujetos discapacitados pueden ser considerados dentro de un valor aceptable de transferencia; en un segundo nivel cabr??a incluir el desarrollo de instrumentos de recogida de informaci??n y de ciertas iniciativas de empleo protegido y apoyado. La actividad m??s relevante en todo el conjunto de proyectos espa??oles ha sido el intercambio de informaci??n y experiencias con los dem??s pa??ses miembros, las visitas de estudio y la participaci??n en reuniones, seminarios y conferencias. Por el contrario, la falta de coordinaci??n interna y de experiencias puede ser contemplada como una de las m??s graves deficiencias apreciadas por esta evaluaci??n final. El presente informe de evaluaci??n final ha de ser estimado y considerado junto a las evaluaciones de proceso realizadas previamente. Las conclusiones y sugerencias se pueden concretar en l??neas de desarrollo normativo aplicadas a la realidad espa??ola. Es necesario articular un sistema de planificaci??n y programaci??n de los proyectos. Los procesos de evaluaci??n, mejoran y mantienen la calidad de los proyectos.

Social network measures for "nosduocentered" networks, their predictive power on performance

Our purpose in this article is to define a network structure which is based on two egos instead of the egocentered (one ego) or the complete network (n egos). We describe the characteristics and properties for this kind of network which we call “nosduocentered network”, comparing it with complete and egocentered networks. The key point for this kind of network is that relations exist between the two main egos and all alters, but relations among others are not observed. After that, we use new social network measures adapted to the nosduocentered network, some of which are based on measures for complete networks such as degree, betweenness, closeness centrality or density, while some others are tailormade for nosduocentered networks. We specify three regression models to predict research performance of PhD students based on these social network measures for different networks such as advice, collaboration, emotional support and trust. Data used are from Slovenian PhD students and their s

Grain size analyses in tin-lead glazes based on 2d-sections

A problem in the archaeometric classification of Catalan Renaissance pottery is the fact, that the clay supply of the pottery workshops was centrally organized by guilds, and therefore usually all potters of a single production centre produced chemically similar ceramics. However, analysing the glazes of the ware usually a large number of inclusions in the glaze is found, which reveal technological differences between single workshops. These inclusions have been used by the potters in order to opacify the transparent glaze and to achieve a white background for further decoration. In order to distinguish different technological preparation procedures of the single workshops, at a Scanning Electron Microscope the chemical composition of those inclusions as well as their size in the two-dimensional cut is recorded. Based on the latter, a frequency distribution of the apparent diameters is estimated for each sample and type of inclusion. Following an approach by S.D. Wicksell (1925), it is principally possible to transform the distributions of the apparent 2D-diameters back to those of the true three-dimensional bodies. The applicability of this approach and its practical problems are examined using different ways of kernel density estimation and Monte-Carlo tests of the methodology. Finally, it is tested in how far the obtained frequency distributions can be used to classify the pottery
