The conceptualization of school and teacher connectedness in adolescent research: A scoping review of literature

This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/ licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.The aim of this scoping review was to map and summarize research relating to school and teacher connectedness, in order to increase current understanding of the ways these terms have been conceptualized in adolescent research. Specifically, this scoping review focuses on the analysis of the actual definitions used and the ways in which school connectedness and teacher connectedness are operationalized in existing measures. Using the terms connectedness, teacher and school as keywords, we searched SCOPUS, Web of Science, ERIC, the Cochrane Library and the EPPI Centre Database of Education Research for relevant peer-review articles published in English from 1990 to 2016. 350 papers were selected for the review. Many studies failed to provide a definition of school or teacher connectedness and there were some differences in the way these constructs were operationalized in the main measures. Future research should be thorough in the definition of these constructs, and ensure consistency between the definition used and the operationalization of the connectedness construct in the selected measure. Unpacking the global concept of school connectedness and examining the role of its different components (global feelings towards school, teacher connectedness, relationships with classmates, etc.) separately may also contribute to building a more coherent body of evidence in this area. Reflecting on the place of school and teacher connectedness in the broader context of the literature on school climate and bridging distances between the research on school connectedness and that on related constructs is another necessary step to move this field forward.Peer reviewedFinal Published versio

Holographic s+p Superconductors

We study the phase diagram of a holographic model realizing a U(2) global symmetry on the boundary and show that at low temperature a phase with both scalar s and vector p condensates exists. This is the s+p-wave phase where the global U(2) symmetry and also the spatial rotational symmetry are spontaneously broken. By studying the free energy we show that this phase is preferred when it exists. We also consider unbalanced configurations where a second chemical potential is turned on. They present a rich phase diagram characterized by the competition and coexistence of the s and p order parameters.Comment: 6 pages, 4 figures; v3: published version, clarifications and references adde

Holographic Type II Goldstone bosons

The Goldstone theorem implies the appearance of an ungapped mode whenever a continuous global symmetry is spontaneously broken. In general it does not say anything about the precise form of the dispersion relation nor does it imply that there is one massless mode for each broken symmetry generator. It is a well-established fact that even for relativistic field theories in the presence of a chemical potential Goldstone modes with quadratic dispersion relation, the type II Goldstone bosons, appear in the spectrum. We develop two holographic models that feature type II Goldstone modes as part of the quasinormal mode spectrum. The models are based on simple generalizations with U(2) symmetry of the well-studied holographic s-wave superfluid. Our results include Goldstone modes without broken generators but with unusual realization of symmetries and a frequency dependent conductivity of striking resemblance to the one of Graphene.Comment: 47 pages, 21 figures; v2: references and clarifications added, typos correcte

Compartmental Models for Infectious Disease

Mathematical modeling is the process of using various mathematical structures to represent real world situations. These models can be used to predict pandemics, natural disasters, population data, and other real world aspects. We can create a model to track a disease’s possible spread. By applying real world data, we can create a simulation of a disease. Using the information gathered from the model, we can understand how an outbreak may behave. The results can be put into perspective to create effective precautions and actions to combat an outbreak

Holographic Superfluids and the Landau Criterion

We revisit the question of stability of holographic superfluids with finite superfluid velocity. Our method is based on applying the Landau criterion to the Quasinormal Mode (QNM) spectrum. In particular we study the QNMs related to the Goldstone modes of spontaneous symmetry breaking with linear and quadratic dispersions.In the linear case we show that the sound velocity becomes negative for large enough superfluid velocity and that the imaginary part of the quasinormal frequency moves to the upper half plane. Since the instability is strongest at finite wavelength, we take this as an indication for the existence of an inhomogeneous or striped condensed phase for large superfluid velocity. In the quadratic case the instability is present for arbitrarily small superfluid velocity.Comment: 26 pages, 10 Figures; v2: authors's name corrected, reference adde

The contribution from relationships with parents and teachers to the adolescent sense of coherence (SOC). Do prosociality and hyperactivity-inattention also play a significant role?

This document is the Accepted Manuscript version. The final, definitive version of this paper has been published in YOUNG, Vol 25 (4), November 2017, doi: https://doi.org/10.1177/1103308816646672, published by SAGE Publishing, All rights reserved.Sense of coherence (SOC) is receiving increasing attention from a number of disciplines interested in the study of adolescent positive development. Given the significant links between SOC and well-being, attention is now moving to the precursors of SOC. The aim of this study was to analyze the contribution of relationships with parents and teachers (contextual factors) to young people’s SOC while taking into account the potential role of individual differences in prosociality and hyperactivity-inattention (individual factors). The sample consisted of 2,979 adolescents aged 15–18 who had participated in the 2010 edition of the World Health Organization (WHO) survey ‘Health Behaviour in School-aged Children’ (HBSC) in Spain. Data were collected by means of anonymous online questionnaires, and statistical analyses included factorial analysis of variance (ANOVA) and analysis of covariance (ANCOVA). Both contextual and individual factors made significant contributions to the adolescents’ SOC. Importantly, the significance of relationships with parents and teachers remained once prosociality and hyperactivity-inattention were taken into account.Peer reviewedFinal Accepted Versio

Cytomegalovirus drug resistance mutations in transplant recipients with suspected resistance

Resistant CMV infections are challenging complications after SOT and HSCT. Prompt recognition of ARMs is imperative for appropriate therapy. 108 plasma samples from 96 CMV + transplant recipients with suspected resistance were analysed in CNM in a retrospective nationwide study from January 2018 to July 2022 for resistance genotyping. ARMs in UL97 and UL54 were found in 26.87% (18/67) and 10.60% (7/66) of patients, respectively. Patients' ARM distribution in UL97 was as follows: L595S n = 3; L595S/M460I n = 1; L595S/N510S n = 1; L595W n = 1; C603W n = 4; A594V n = 3; A594E n = 1; C607Y n = 1; L397R/T409M/H411L/M460I n = 1; L397I n = 1; H520Q n = 1; four patients showed ARMs in UL54 as well (F412C n = 1; T503I n = 2; P522S n = 1), whereas three patients exhibited ARMs in UL54 only (L501I/T503I/L516R/A834P n = 1; A987G n = 2). L516R in UL54 and L397R/I and H411L in UL97 have been found for the first time in a clinical sample. L595S/W was the most prevalent ARM found to lend resistance to GCV. In UL54 all ARMs lent resistance to GCV and CDV. In addition, A834P, found in one patient, also lent resistance to FOS. CMV load did not differ significantly in patients with or without ARMs, and no differences were found either between patients with ARMs in UL97 or in UL97 and UL54. Despite extensive use of classical antivirals for the treatment of CMV infection after HSCT and SOT, ARMs occurred mainly in viral UL97 kinase, which suggests that CDV and mostly FOS continue to be useful alternatives to nucleoside analogues after genotypic detection of ARMs.This work was supported by a grant from Instituto de Salud Carlos III.

Autonomous video compression system for environmental monitoring

[EN] The monitoring of natural environments is becoming a very controversial topic because people are more and more concerned about preserving and monitoring these natural spaces. The monitoring tasks are usually complemented with a network infrastructure composed by cameras and network devices that make easy the remote visualization of the monitored environments. This work presents the design, implementation and test of an autonomous video compression system for environmental monitoring. The system is based on a server in charge of collecting the videos and analyzing the network constraints. As a function of the measured parameters and the predominant color of the requested video, the system determines the best compression codec for transmitting the video through the network. Additionally, the server should run an algorithm developed in Python and MATLAB(c) in charge of analyzing the RED-GREEN-BLUE (RGB) components of the video and performing the transcoding tasks. The system has been tested with different videos and the results of Quality of Service (QoS) and Quality of Experience (QoE) shows that H264 is a good option when the predominant color of videos are black or white while XVID is one the codecs that offer interesting results when colors as red, green or blue are predominant in the video.This work has been supported by the Programa para la Formación de Personal Investigador (FPI-2015-S2-884) by the Universitat Politecnica de Valencia .
