“Sobrevoando” a deficiência: do que os portugueses pensam ao que os políticos fazem
Creators: name: Sanches, Isabel
Publisher: name: Interacções
Year: 2015

description: Este “olhar” sobre a deficiência, em Portugal, procura dar conta do que para os portugueses significa ser contemplado com uma deficiência e de como os seus contextos a acolhem e a “tratam”. Constatou-se, através da reflexão que se fez, em função dos testemunhos vivenciados e escritos, que nascer deficiente ou adquirir a deficiência, é a maior tragédia que pode acontecer ao próprio e aos familiares (e não tem que ser!). Uma cultura de inferiorização, de incapacidade, de inutilidade e de comiseração está patente nas relações entre os ditos «normais» e os considerados deficientes, também presente nas próprias políticas sociais. A evolução das políticas e a sua operacionalização não têm acompanhado as várias conceções sobre a deficiência, desde o modelo médico até ao paradigma da cidadania.

description: In course of the MUCHFUSS project we found two new HW Virginis systems. J192059+372220 (J1920) has an orbital period of 0.169 d and an M dwarf companion with a mass of $0.116 M_{\odot}$. J162256+473051 (J1622) has the shortest period (0.069 d) of all known HW Virginis systems. Its companion has a mass of $0.0635\pm 0.004 M_{\odot}$ and is therefore the second close brown dwarf found orbiting a subdwarf B star.

description: The particle filtration efficiency (PFE) of a respirator or face mask is one of its key properties. While the physics of particle filtration results in the PFE being size-dependent, measurement standards are specified using a single, integrated PFE, for simplicity. This integrated PFE is commonly defined concerning either the number (NPFE) or mass (MPFE) distribution of particles as a function of size. This relationship is non-trivial; it is influenced by both the shape of the particle distribution and the fact that multiple practical definitions of particle size are used. This manuscript discusses the relationship between NPFE and MPFE in detail, providing a guide to practitioners. Our discussion begins with a description of the theory underlying different variants of PFE. We then present experimental results for a database of size-resolved PFE (SPFE) measurements for several thousand candidate respirators and filter media, including filter media with systematically varied properties and commercial samples that span 20%–99.8% MPFE. The observed relationships between NPFE and MPFE are discussed in terms of the most-penetrating particle size (MPPS) and charge state of the media. For the sodium chloride particles used here, we observed that the MPFE was greater than NPFE for charged materials and vice versa for uncharged materials. This relationship is observed because a shift from NPFE to MPFE weights the distribution toward larger sizes, while charged materials shift the MPPS to smaller sizes. Results are validated by comparing the output of a pair of automated filter testers, which are used in gauging standards compliance, to that of MPFE computed from a system capable of measuring SPFE over the 20 nm–500 nm range.

description: We report an experimental and computational study of the Hall effect in Mn$_{\rm 1-x}$Fe$_{\rm x}$Si, as complemented by measurements in Mn$_{\rm 1-x}$Co$_{\rm x}$Si, when helimagnetic order is suppressed under substitutional doping. For small $x$ the anomalous Hall effect (AHE) and the topological Hall effect (THE) change sign. Under larger doping the AHE remains small and consistent with the magnetization, while the THE grows by over a factor of ten. Both the sign and the magnitude of the AHE and the THE are in excellent agreement with calculations based on density functional theory. Our study provides the long-sought material-specific microscopic justification, that while the AHE is due to the reciprocal-space Berry curvature, the THE originates in real-space Berry phases.

description: Numerous health and safety hazards exist at U.S. onshore oil and gas extraction worksites. Higher fatal injury rates have been reported among drilling and servicing companies, which are more likely to employ workers in construction and extraction occupations, compared to operators that employ more workers in management and office and administrative support roles. However, there is little information describing the extent to which workers encounter these hazards, are provided hazard mitigation strategies by their employers, or use personal protective equipment (PPE). A cross-sectional survey of 472 U.S. oil and gas extraction workers was conducted to identify and characterize factors related to on-the-job fatalities, injuries, and illnesses and determine workers’ health and safety concerns. Workers were employed by servicing companies (271/472, 57.4%), drilling contractors (106/472, 22.5%), and operators (95/472, 20.1%). The likelihood of contact with hazardous substances varied by substance and company type. Drilling and servicing employees had significantly higher odds of self-reported contact with pipe dope (ORdrilling = 10.07, 95% CI: 1.74–63.64; ORservicing = 5.95, 95% CI: 2.18–18.34), diesel exhaust (ORdrilling = 2.28, 95% CI: 1.15–5.05; ORservicing = 4.93, 95% CI: 2.73–10.32), and drilling mud (ORdrilling = 24.36, 95% CI: 4.45–144.69; ORservicing = 3.48, 95% CI: 1.24–12.20), compared to operators. Safety policies, programs, and trainings were commonly reported by workers, although substance-specific training (e.g., respirable crystalline silica hazards) was less common. Differences in self-reported employer PPE requirements and worker use of PPE when needed or required for safety highlight a need for novel strategies to improve the use of PPE. Overall, this study highlights differences in work conditions by company type and uncovers gaps in employer administrative controls and PPE use.

description: Abstract

Tinea capitis, a common fungal infection primarily affecting children, presents challenges in diagnosis and management. This review provides a comprehensive overview of tinea capitis, including epidemiology, etiology, clinical manifestations, diagnostic approaches, treatment options, and prevention strategies. Epidemiological studies highlight the increasing incidence of tinea capitis worldwide, with varying prevalence rates across different regions and populations. The etiology involves dermatophyte fungi, primarily Trichophyton species, transmitted through direct contact with infected individuals or contaminated objects. Clinical manifestations range from inflammatory to non-inflammatory types, with diverse presentations and potential complications. Diagnostic approaches encompass direct microscopy, fungal culture, molecular techniques, Wood's lamp examination, and distinguishing features from other scalp conditions. Treatment modalities include systemic and topical antifungal agents, with considerations for special populations and adjunctive therapies. Prevention strategies emphasize personal hygiene practices, environmental measures, and education campaigns to mitigate transmission and reduce the burden of tinea capitis. Emerging research focuses on novel therapeutic approaches, including nanotechnology-based antifungals and host-targeted therapies. Overall, this review highlights the importance of early recognition, accurate diagnosis, and tailored management strategies in addressing tinea capitis effectively.

description: A diversidade é uma riqueza que importa saber preservar e apreciar (César, 2012b). Em Portugal, a região do Algarve apresenta um elevado índice de insucesso académico, sobretudo no 3.º ciclo do ensino básico (INE, 2009). Este fenómeno é mais frequente nos meios rurais (INE-DRA, 2004). Alguns autores observam conexões entre a construção de cenários educativos (mais) inclusivos, nos meios rurais, e as perspectivas assumidas por professores, alunos e encarregados de educação face à Educação Inclusiva (EI) (Loreman, Lupart, McGhie-Richmond, & Barber, 2008; Loreman, McGhie-Richmond, Barber, & Lupart, 2009; McGhie-Richmond, Barber, Lupart, & Loreman, 2009). O objectivo principal desta investigação consiste em conhecer as perspectivas face EI dos professores, alunos e encarregados de educação, referentes a escolas do 3.º ciclo do ensino básico regular diurno, nas áreas predominantemente rurais, da região do Algarve. Assumindo um paradigma interpretativo (Denzin, 2002), desenvolvemos um estudo de caso intrínseco (Stake, 1995). Os participantes são 151 professores, 471 alunos e 455 encarregados de educação. Os instrumentos de recolha de dados são a recolha documental e três escalas: (1) a escala TPIRC – Teacher Perceptions of Inclusion in Rural Canada (McGhie-Richmond et al., 2009); (2) a escala SPIRC – Student Perceptions of Inclusion in Rural Canada (Loreman et al., 2008); e (3) a escala PPIERC – Parent Perspectives on Inclusive Education in Rural Canada (Loreman et al., 2009). Este estudo mostra que os professores, alunos e respectivos encarregados de educação assumem perspectivas pouco inclusivas. Os alunos e encarregados de educação seleccionam posições pouco inclusivas face ao acesso ao envolvimento na comunidade. A análise dos dados permite inferir que muitos destes participantes se confrontam com formas subtis de exclusão cultural, o que sublinha a necessidade de facilitar o acesso a formas mais inclusivas de participação social.

description: We analyse the role of vertex operator algebra and 2d amplitudes from the point of view of the representation theory of infinite dimensional Lie algebras, MacMahon and Ruelle functions. A p-dimensional MacMahon function is the generating function of p-dimensional partitions of integers. These functions can be represented as amplitudes of a two-dimensional c=1 CFT. In this paper we show that p-dimensional MacMahon functions can be rewritten in terms of Ruelle spectral functions, whose spectrum is encoded in the Patterson-Selberg function of three dimensional hyperbolic geometry.

description: The use of filtering facepiece respirators (FFRs) of various types increased dramatically by both workers and the public during the ongoing COVID-19 pandemic. This increased use has, likewise, instigated a proliferation of research on the qualities of FFRs. An aspect of FFR development and optimization involves the use of mathematical models that predict filter efficiency based on various filter characteristics while also considering a number of particle capture forces. An evaluation of current literature failed to identify a publication that provides a comprehensive assessment of the models developed to predict filter efficiency. The purpose of this review was, therefore, to describe models developed to include the forces associated with diffusion, interception, impaction, and electrostatic attraction as they contribute to the efficiency of an entire filter. The literature review was augmented with figures created with the use of many of the models discussed to compare between different models of the same force as well as to illustrate the influence of electrostatic forces on overall filter efficiency.

description: The $^{18}$Ne($α$,$p$)$^{21}$Na reaction is thought to be one of the key breakout reactions from the hot CNO cycles to the rp-process in type I x-ray bursts. In this work, the resonant properties of the compound nucleus $^{22}$Mg have been investigated by measuring the resonant elastic scattering of $^{21}$Na+$p$. An 89 MeV $^{21}$Na radioactive beam delivered from the CNS Radioactive Ion Beam Separator bombarded an 8.8 mg/cm$^2$ thick polyethylene (CH$_{2}$)$_{n}$ target. The $^{21}$Na beam intensity was about 2$\times$10$^{5}$ pps, with a purity of about 70% on target. The recoiled protons were measured at the center-of-mass scattering angles of $θ_{c.m.}$$\approx$175.2${^\circ}$, 152.2${^\circ}$, and 150.5${^\circ}$ by three sets of $ΔE$-$E$ telescopes, respectively. The excitation function was obtained with the thick-target method over energies $E_x$($^{22}$Mg)=5.5--9.2 MeV. In total, 23 states above the proton-threshold in $^{22}$Mg were observed, and their resonant parameters were determined via an $R$-matrix analysis of the excitation functions. We have made several new $J^π$ assignments and confirmed some tentative assignments made in previous work. The thermonuclear $^{18}$Ne($α$,$p$)$^{21}$Na rate has been recalculated based on our recommended spin-parity assignments. The astrophysical impact of our new rate has been investigated through one-zone postprocessing x-ray burst calculations. We find that the $^{18}$Ne($α$,$p$)$^{21}$Na rate significantly affects the peak nuclear energy generation rate, reaction fluxes, as well as the onset temperature of this breakout reaction in these astrophysical phenomena.

Puesto que en la investigación EANCYT se han aplicado un gran número (82) de las cuestiones que forman el cuestionario de opiniones sobre ciencia tecnología y sociedad (COCTS), las más de 230000 respuestas de cerca de 4000 estudiantes participantes en la investigación ofrecen un conjunto de datos empíricos sólido para un doble objetivo: el diagnóstico de las concepciones sobre la naturaleza de la ciencia y tecnología (NdCyT) sobre una gran variedad de temas y cuestiones y la verificación empírica global de la eficacia de las secuencias de enseñanza aprendizaje aplicadas para mejorar las concepciones de los estudiantes sobre la NdCyT. Las concepciones de los estudiantes son pobres, y ofrecen rasgos de inconsistencia importantes que las hacen superficiales. Los resultados sobre la eficacia de las secuencias de enseñanza son cuantitativamente modestos pero muestran indicadores y tendencias de mejora claras en los grupos experimentales que recibieron enseñanza mediante las secuencias y cuyos cambios más relevantes pertenecen, principalmente, a temas sociales e institucionales de la comunidad científica. Se discuten algunas implicaciones educativas y las limitaciones de este análisis global que comprende datos muy heterogéneos.

description: A compact Raman LIDAR system with a spectrograph was used for express ice thickness measurements. The difference between the Raman spectra of ice and liquid water is employed to locate the ice-water interface while elastic scattering was used for air-ice surface detection. This approach yields an error of only 2 mm for an 80-mm-thick ice sample, indicating that it is promising express noncontact thickness measurements technique in field experiments.

description: El principal objetivo de este trabajo es estudiar las creencias de profesorado de Educación Primaria en formación inicial sobre algunos aspectos relacionados con la naturaleza de la ciencia (NdC) y evaluar el potencial de la secuencia de enseñanza aprendizaje (SEA) “Investigando dragones” para promover actitudes más adecuadas sobre la NdC. Para ello se ha aplicado un diseño de investigación pre-test/pos-test utilizando como instrumento de evaluación un conjunto de cuestiones del Cuestionario de Opiniones sobre Ciencia Tecnología y Sociedad (COCTS) relacionadas con la epistemología y la sociología interna de la ciencia. Los resultados ponen de manifiesto la existencia de creencias ingenuas en el profesorado en formación inicial, relacionadas con la objetividad de las observaciones y las teorías científicas, con la provisionalidad del conocimiento científico y con la naturaleza de las leyes y las teorías científicas. Estas creencias ingenuas se reducen en más de un 7% tras la aplicación de la SEA “Investigando dragones”. El análisis de los índices actitudinales globales por cuestión y por categoría aporta una visión más compleja y pone de manifiesto el gran desafío asociado al cambio de actitudes sobre la NdC, mostrando limitaciones y sugiriendo futuras líneas de trabajo.

description: By using the Nikiforov-Uvarov method, we give the approximate analytical solutions of the Dirac equation with the shifted Deng-Fan potential including the Yukawa-like tensor interaction under the spin and pseudospin symmetry conditions. After using an improved approximation scheme, we solved the resulting schrödinger-like equation analytically. Numerical results of the energy eigenvalues are also obtained, as expected, the tensor interaction removes degeneracies between spin and pseudospin doublets.

description: Der Anspruch, wie landwirtschaftliche Nutztiere auf Basis des Österreichischen Tierschutzgesetzes gehalten werden sollten und die Realität insbesondere der Intensivtierhaltung klaffen weit auseinander. Nebst dem Umstand, dass Tierhalter reichlich den Interpretationsspielraum des Tierschutzgesetzes ausnutzen und der Vollzug des Tierschutzgesetzes zu wünschen übrig lässt, wird vor allem der Inhalt verschiedener Bestimmungen des Tierschutzgesetzes durch Regelungen insbesondere der 1. Tierhaltungsverordnung aufgeweicht oder manchmal sogar konterkariert. Die Biologie der Tiere wird viel zu wenig berücksichtig. So sind Tierhaltungen oft tierschutzwidrig, aber nicht tierschutzrechtswidrig. Der vorliegende Beitrag soll diese Widersprüchlichkeit aufzeigen.

description: In this letter, a simple technique is proposed to induce strong density modulation into the electron beam with small energy modulation. By using the combination of a transversely dispersed electron beam and a wave-front tilted seed laser, three-dimensional manipulation of the electron beam phase space can be utilized to significantly enhance the micro-bunching of seeded free-electron laser schemes, which will improve the performance and extend the short-wavelength range of a single-stage seeded free-electron laser. Theoretical analysis and numerical simulations demonstrate the capability of the proposed technique in a soft x-ray free-electron laser.

description: In the early morning hours of June 1, 2009, during a flight from Rio de Janeiro to Paris, Air France Flight AF 447 disappeared during stormy weather over a remote part of the Atlantic carrying 228 passengers and crew to their deaths. After two years of unsuccessful search, the authors were asked by the French Bureau d'Enquêtes et d'Analyses pour la sécurité de l'aviation to develop a probability distribution for the location of the wreckage that accounted for all information about the crash location as well as for previous search efforts. We used a Bayesian procedure developed for search planning to produce the posterior target location distribution. This distribution was used to guide the search in the third year, and the wreckage was found with one week of undersea search. In this paper we discuss why Bayesian analysis is ideally suited to solving this problem, review previous non-Bayesian efforts, and describe the methodology used to produce the posterior probability distribution for the location of the wreck.

description: Esta investigação envolveu problemas relacionados ao ensinar com qualidade a Natureza da Ciência e Tecnologia (NdC&T). O objetivo foi mostrar a possibilidade de ensinar e analisar questões e aspectos inovadores da compreensão da NdC&T, tendo como iniciativa uma intervenção didática realizada em sala de aula em um curso de formação de professores com auxílio de uma Sequência de Ensino-Aprendizagem (SEA). A abordagem metodológica foi uma intervenção-experimental, pois reuniu etapas de pré-teste – intervenção didática - pós-teste, com um grupo experimental e grupo controle. Foram participantes da pesquisa estudantes do último ano de graduação (licenciatura) em Ciências Biológicas de uma instituição privada da cidade de São Paulo. Entre os resultados verifica-se uma modesta melhora do pré-teste para o pós-teste com o grupo controle e o grupo experimental uma melhora expressiva, superando o grupo controle. Ademais com esse trabalho foi possível identificar as áreas onde foram produzidas melhoras. Como contribuição essa pesquisa inclui a própria SEA e os instrumentos de avaliação, sendo que pode-se constatar sua funcionalidade, tornando-se transferíveis para Ensino de Ciências. Concluímos que através da atividade desenhada, realizada e avaliada em sala de aula, possibilitou aos estudantes alcançar uma melhora nas concepções atitudinais acerca da NdC&T.

Chandra Survey of Nearby Highly Inclined Disc Galaxies - III: Comparison with Hydrodynamical Simulations of Circumgalactic Coronae

description: X-ray observations of circumgalactic coronae provide a valuable means by which to test galaxy formation theories. Two primary mechanisms are thought to be responsible for the establishment of such coronae: accretion of intergalactic gas (IGM) and/or galactic feedback. In this paper, we first compare our Chandra sample of galactic coronae of 53 nearby highly-inclined disc galaxies to an analytical model considering only the accretion of IGM. We confirm the existing conclusion that this pure accretion model substantially over-predicts the coronal emission. We then select 30 field galaxies from our original sample, and correct their coronal luminosities to uniformly compare them to deep X-ray measurements of several massive disc galaxies from the literature, as well as to a comparable sample of simulated galaxies drawn from the Galaxies-Intergalactic Medium Interaction Calculation (GIMIC). These simulations explicitly model both accretion and SNe feedback and yield galaxies exhibit X-ray properties in broad agreement with our observational sample. However, notable and potentially instructive discrepancies exist between the slope and scatter of the Lx-M200 and Lx-SFR relations, highlighting some known shortcomings of GIMIC, e.g., the absence of AGN feedback, and possibly the adoption of constant stellar feedback parameters. The simulated galaxies exhibit a tight Lx-M200 correlation with little scatter. Having inferred M200 for our observational sample via the Tully-Fisher relation, we find a weaker and more scattered correlation. In the simulated and observed samples alike, massive non-starburst galaxies above a typical transition mass of M*~2e11Msun or M200~1e13Msun tend to have higher Lx/M* and Lx/M200 than low-mass counterparts, indicating that the accretion of IGM plays an increasingly important role in establishing the observable hot circumgalactic medium with increasing galaxy mass.

description: Este artículo presenta la experiencia formativa que desarrolló una profesora colaboradora del proyecto EANCYT, al aplicar la Secuencia de Enseñanza y Aprendizaje-SEA- “Predecir el Clima”, en un curso de ciencias naturales para estudiantes de grado 6º (11-12 años), con el propósito de enseñar un tema específico de Naturaleza de Ciencia y Tecnología relacionado con la investigación y el desarrollo (I+D). En el proceso de investigación, la profesora realiza una planeación reflexiva de su actividad, que le permite comprender qué deben aprender sus estudiantes en relación con el trabajo científico y tecnológico; reflexiona sobre su enseñanza y el uso de actividades significativas de aprendizaje que incluyen el planteamiento de problemas, la formulación de hipótesis, el diseño experimental y la generación de conclusiones sobre los fenómenos cotidianos que determinan el clima. La profesora utiliza dos formas complementarias para recoger y presentar por escrito la información relacionada con el Conocimiento Didáctico del Contenido (CDC) propuestas por Loughran y otros (2012) y adaptadas por Vázquez (2014), que le permiten dar cuenta de la construcción de nuevos conocimientos relacionados con la NdCyT en la enseñanza de las ciencias naturales y reconocer la importancia de favorecer aprendizajes integrales y con sentido para los estudiantes.
