"Psicologización y feminización": de la novela inglesa de ficción doméstica a la psicología de las revistas "femeninas" de divulgación
This project aims to analyze the problematic links between the historical processes of feminization and psychologizing, from the period conventionally known as “modernity”. According to Nancy Armstrong (1987/1991) about the rise of domestic fiction novel in England, will discuss the extent to which the imperatives of bourgeois femininity –collected and reorganized in these media-narrative– allowed the establishment of a psychological subjectivity innovatively. Before psychology came to be institutionalized, many of its future disciplinary domains were already in the domestic fiction. Our hypothesis, therefore, is to suggest that bourgeois codes –that tried to regulate an idea of the feminity focused on domesticity– promoted, at the same time, certain conditions for the emergence of psychology. After making a genealogy of such novels and reviewing some of the most important elements in the hybridization between psychologizing and feminization, we see the forms of regulation procured by these historical plots today. Specifically, we address this alliance through disclosure magazines aimed at women with the title “psychology”El presente proyecto tiene por objetivo analizar los problemáticos vínculos entre los procesos históricos de feminización y psicologización, a partir del periodo que conocemos convencionalmente como “modernidad”. Tomando como referencia el trabajo de Nancy Armstrong (1987/1991) sobre el surgimiento de la novela de ficción doméstica en Inglaterra, discutiremos en qué medida los imperativos de la feminidad burguesa –recogidos y reorganizados en estos soportes narrativos– posibilitaron la constitución de una subjetividad novedosamente psicológica. Antes de que la psicología deviniese en institución, muchos de sus futuros dominios disciplinares ya circulaban, en cierto modo, en la literatura de ficción doméstica. Nuestra hipótesis, por tanto, consiste en sugerir que los códigos burgueses –que trataron de regular una idea de lo femenino centrada en la domesticidad– avalaron, al mismo tiempo, determinadas condiciones de emergencia para la psicologización del yo y de la cultura. Tras esbozar una genealogía de este tipo de novelas y repasar algunos de los elementos más relevantes en la hibridación entre psicologización y feminización, veremos las formas de regulación procuradas por estas tramas históricas en la actualidad. En concreto, daremos cuenta de esta alianza a través de las revistas de divulgación dirigidas a mujeres con título “psicología”
Word embeddings for retrieving tabular data from research publications
Scientists face challenges when finding datasets related to their research problems due to the limitations of current dataset search engines. Existing tools for searching research datasets rely on publication content or metadata, do not considering the data contained in the publication in the form of tables. Moreover, scientists require more elaborate inputs and functionalities to retrieve different parts of an article, such as data presented in tables, based on their search purposes. Therefore, this paper proposes a novel approach to retrieve relevant tabular datasets from publications. The input of our system is a research problem stated as an abstract from a scientific paper, and the output is a set of relevant tables from publications that are related to the research problem. This approach aims to provide a better solution for scientists to find useful datasets that support them in addressing their research problems. To validate this approach, experiments were conducted using word embedding from different language models to calculate the semantic similarity between abstracts and tables. The results showed that contextual models significantly outperformed non-contextual models, especially when pre-trained with scientific data. Furthermore, the importance of context was found to be crucial for improving the results.Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.

Zn-Promoted Selective Gas-Phase Hydrogenation of Tertiary and Secondary C4 Alkynols over Supported Pd
We have investigated the gas-phase (P = 1 atm; T = 373 K) hydrogenation of (tertiary alkynol) 2-methyl-3-butyn-2-ol (MBY) and (secondary) 3-butyn-2-ol (BY) over a series of carbon (C), non-reducible (Al2O3 and MgO), and reducible (CeO2 and ZnO) supported monometallic [Pd (0.6–1.2% wt) and Zn (1% wt)] and bimetallic Pd–Zn (Pd:Zn mol ratio = 95:5, 70:30, and 30:70) catalysts synthesized by deposition–precipitation and colloidal deposition. The catalysts have been characterized by H2 chemisorption, hydrogen temperature-programmed desorption (H2-TPD), specific surface area (SSA), X-ray photoelectron spectroscopy (XPS), and transmission (TEM) and scanning transmission electron microscopy (STEM) analyses. Reaction over these catalysts generated the target alkenol [2-methyl-3-buten-2-ol (MBE) and 3-buten-2-ol (BE)] through partial hydrogenation and alkanol [2-methyl-butan-2-ol (MBA) and 2-butanol (BA)]/ketone [2-butanone (BONE)] as a result of full hydrogenation and double-bond migration. The catalysts exhibit a similar Pd nanoparticle size (2.7 ± 0.3 nm) but a modified electronic character (based on XPS). Hydrogenation activity is linked to surface hydrogen (from H2 chemisorption and H2-TPD). An increase in H2:alkynol (from 1 → 10) results in enhanced alkynol consumption with a greater rate in the transformation of MBY (vs BY); H2:alkynol had negligible effect on product distribution. Reaction selectivity is insensitive to the Pd site electron density with a similar response (SMBE = 65 ± 9% and SBE = 70 ± 8%) over Pdδ− (on Al2O3 and MgO) and Pdδ+ (on C and CeO2). A Pd/ZnO catalyst delivered enhanced alkenol selectivity (SMBE = 90% and SBE = 96%) attributed to PdZn alloy phase formation (proved by XRD and XPS) but low activity, ascribed to metal encapsulation. A two-fold increase in the consumption rate was recorded for Pd–Zn/Al2O3 (30:70) versus Pd/ZnO with a similar alloy content (32 ± 4% from XPS), ascribed to a contribution due to spillover hydrogen (from H2-TPD) where high alkenol selectivity was maintained.This research was funded by the Engineering and Physical Sciences Research Council (EPRSC; grant number EP/L016419/1; Ph.D. studentship to A.G.-F., CRITICAT program), the Spanish Ministerio de Ciencia Innovación y Universidades, Generalitat Valenciana and FEDER (RTI2018-095291-B-I00, MAT2017-87579-R MINECO/FEDER and PROMETEO/2018/076)
Distribution of polymorphisms IL4 -590 C/T and IL4 RP2 in the human populations of Madeira, Azores, Portugal, Cape
Abstract: The IL4 gene is located on chromosome 5q23.3-31.2. Polymorphisms within this cytokine gene, like the derivative allele T of IL4-590, have been reported as being associated to elevated IgE serum levels and asthma. In the present work, the allelic and genotypic frequency of the IL4-590 and IL4 RP2 polymorphisms was carried out in 599 individuals from Madeira, Azores, Portugal mainland, Cape Verde and Guinea-Bissau and in a sample of 101 asthmatics from Madeira population. In all populations the polymorphisms were in LD and presented a significant dissimilar allelic and genotypic distribution (p<0.05) except between mainland Portugal and Madeira when compared
to Azores. Significant differences regarding both loci were found between Madeira population and the group of asthmatics.
Genotype 183183TT frequency is higher for African populations while 253253CC prevails in Caucasian populations.
The existence of a Hardy-Weinberg Disequilibrium in Guinea-Bissau population not observed in neutral markers
leads to the hypothesis of natural selection occurring in these loci probably associated to a rapid population
growth an hypothesis strengthened by neutral STRs D5S818 and CSF1PO gene diversity.info:eu-repo/semantics/publishedVersio
Factores de rendimiento en el desplazamiento del tenista influenciados por el calzado.
Los desplazamientos laterales son de gran importancia en el tenis. Sin embargo, no ha sido publicado ningún estudio sobre el efecto del calzado sobre el rendimiento en este tipo de movimientos. En el estudio participaron 5 jugadores habituales de tenis y se analizaron 10 calzados comerciales de tenis. El movimiento estudiado consistió en un desplazamiento lateral con parada y cambio de sentido, registrándose las fuerzas mediante una plataforma dinamométrica Dinascan-IBV y grabándose el movimiento con dos cámaras de vídeo S-VHS Panasonic WV-BL600. Los resultados de los ANOVAs realizados mostraron que algunas de las variables analizadas eran dependientes del calzado (p < 0.05). De éstas, destacan (1) la supinación máxima de la subastragalina y (2) el tiempo de apoyo. Se detectaron varias correlaciones (Pearson) significativas (p < 0.05) de especial relevancia, destacando la correlación positiva entre el tiempo de apoyo con los máximos de supinación. Como el impulso mecánico no se ha visto afectado por el calzado, esto indica que el calzado que limita la supinación permite realizar el movimiento analizado en un menor tiempo.Sideward cutting movements are very important in tennis. However, no studies on their effect on performance have been published. 5 tennis players (age 21.5 ± 0.8, weight 75.2 ± 2.8 kg, height, 1.78 ± 0.05 m) participated in the study on a voluntary basis and 10 tennis shoes were analysed. Subjects perform a sideward cutting movement. An extensometric force plate (Dinascan-IBV) was used to record the kinetic variables and 2 video cameras (Panasonic-WV-BL600) were utilized for the kinematic variables. ANOVA results showed several variables as shoe-dependent (p < 0.05), among these stands out (1) rearfoot supination movement and (2) contact time. Moreover these variables were positively correlated (p < 0.05). As mechanical impulse was not change, this means that shoes that limit supination allow perform sideward cutting movements [email protected] [email protected] [email protected]
Modification of Angular Kinematics and Spatiotemporal Parameters during Running after Central and Peripheral Fatigue
Fatigue causes kinematics modifications during running, and it could be related to injuries. The aim was to identify and compare the effects of central and peripheral fatigue on angular kinematics and spatiotemporal parameters during running. Angular kinematics and spatiotemporal parameters were evaluated using an infrared motion capture system and were registered during 2 min treadmill running in pre- and post-fatigue states in eighteen male recreational runners. Central fatigue was induced by a 30 min running fatigue protocol on a treadmill, while peripheral fatigue in quadriceps and hamstrings muscles was induced by an isokinetic dynamometer fatigue protocol. Central fatigue increased the anterior shank oscillation during the initial contact, knee flexion during the maximum absorption, posterior shank oscillation during propulsion, and stance time (p < 0.05). Peripheral fatigue decreased ankle dorsiflexion during initial contact and increased knee flexion and posterior shank oscillation during propulsion (p < 0.05). Moreover, central fatigue increased to a greater extent the hip and knee flexion and ankle dorsiflexion during initial contact and maximum absorption as well as stance time and propulsion time (p < 0.05). These results suggested that central fatigue causes greater increases in the range of movements during the midstance than peripheral fatigue
Validity and Reliability of an Instrumented Treadmill with an Accelerometry System for Assessment of Spatio-Temporal Parameters and Impact Transmission
Running retraining programs focused on concurrent feedback of acceleration impacts have been demonstrated to be a good strategy to reduce running-related injuries (RRI), as well as to improve running economy and reduce acceleration impacts and injury running incidence. Traditionally, impacts have been registered by mean of accelerometers attached directly to the athletes, which is inaccessible to the entire population, because it requires laboratory conditions. This study investigated the validity and reliability of a new device integrated directly into the treadmill, compared to a traditional acceleration impact system. Thirty healthy athletes with no history of RRI were tested on two separate days over the instrumented treadmill (AccTrea) and simultaneously with an acceleration impact system attached to the participant (AccAthl). AccTrea was demonstrated to be a valid and reliable tool for measuring spatio-temporal parameters like step length (validity intraclass correlation coefficient (ICC) = 0.94; reliability ICC = 0.92), step time (validity ICC = 0.95; reliability ICC = 0.96), and step frequency (validity ICC = 0.95; reliability ICC = 0.96) during running. Peak acceleration impact variables showed a high reliability for the left (reliability ICC = 0.88) and right leg (reliability ICC = 0.85), and peak impact asymmetry showed a modest validity (ICC = 0.55). These results indicated that the AccTrea system is a valid and reliable way to assess spatio-temporal variables, and a reliable tool for measuring acceleration impacts during running.This research was funded by Bodytone International Sport, S.L., grant number CFE-BODYTONE-03-18

Extended Endoscopic Endonasal Approaches for Cerebral Aneurysms: Anatomical, Virtual Reality and Morphometric Study
Introduction. The purpose of the present contribution is to perform a detailed anatomic and virtual reality three-dimensional stereoscopic study in order to test the effectiveness of the extended endoscopic endonasal approaches for selected anterior and posterior circulation aneurysms. Methods. The study was divided in two main steps: (1) simulation step, using a dedicated Virtual Reality System (Dextroscope, Volume Interactions); (2) dissection step, in which the feasibility to reach specific vascular territory via the nose was verified in the anatomical laboratory. Results. Good visualization and proximal and distal vascular control of the main midline anterior and posterior circulation territory were achieved during the simulation step as well as in the dissection step (anterior communicating complex, internal carotid, ophthalmic, superior hypophyseal, posterior cerebral and posterior communicating, basilar, superior cerebellar, anterior inferior cerebellar, vertebral, and posterior inferior cerebellar arteries). Conclusion. The present contribution is intended as strictly anatomic study in which we highlighted some specific anterior and posterior circulation aneurysms that can be reached via the nose. For clinical applications of these approaches, some relevant complications, mainly related to the endonasal route, such as proximal and distal vascular control, major arterial bleeding, postoperative cerebrospinal fluid leak, and olfactory disturbances must be considered
