Dialogando sobre educação em saúde e ética a partir da experiência do curso técnico em saúde comunitária do Movimento dos Trabalhadores Rurais Sem Terra
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde, Programa de Pós-Graduação em Saúde Pública, Florianópolis, 2009Trata-se de uma pesquisa descritivo-exploratória, realizada com sete egressos do Curso Técnico em Saúde Comunitária (CTSC) do Movimento dos Trabalhadores Rurais Sem Terra (MST). Seu principal objetivo foi analisar interações entre educação em saúde - questões éticas - questões políticas no cotidiano dos egressos do curso técnico em saúde comunitária do MST. A pesquisa mesclou pesquisa qualitativa com a Investigação Temática proposta por Paulo Freire. Com a exploração, inferência e interpretação do material de pesquisa foram encontradas cinco categorias, quatro que surgiram do momento específico de coleta de dados e uma que surgiu do próprio cenário de pesquisa, foram elas: (1) a amenidade do setor saúde; (2) saída dos militantes e estagnação do setor de saúde; (3) no curso aprendemos a lidar e valorizar o ser humano como um todo; (4) educação em saúde deve estar ligada a um projeto de sociedade; (5) quando precisa, o setor de saúde da conta. No processo de interpretação do material estas categorias foram agrupadas em três grandes grupos temáticos: Contra-hegemonia do setor saúde no interior do movimento, trabalho em saúde e educação em saúde. Com esta organização foi percebida a transversalidade da categoria: No curso aprendemos a lidar e valorizar o ser humano como um todo. Demonstrou-se como característica do processo de formação do MST uma contraposição a formação fragmentada ainda hoje hegemônica nos cursos da área da saúde, o que contribuiu para a compreensão de um dos principais desafios na formação de profissionais para atuarem no SUS: estimular processos educativos articulados com lutas maiores dos movimentos sociais, contribuindo para uma formação não fragmentada em que as pessoas são compreendidas como sujeitos históricos, sociais e coletivos.This is a descriptive-exploratory study, conducted with seven graduates of the Technical Course in Community Health (CTSC) of the Landless Workers Movement (MST). Its main objective was to analyze interactions between health education - ethical issues - political issues in the daily lives of the community health technicians of MST. The research blended qualitative research with the Thematic Research proposed by Paulo Freire. With the exploration, inference and interpretation of the research material were found five categories, four of which emerged in the time of collecting specific data and one that came out in the setting of research itself, they were: (1) the amenity of the health sector; (2) the output of the militants and health sector stagnation; (3) in the course we learned how to deal and to value with the human being as a whole; (4) health education should be linked to a society project; (5) when you need the health sector works. In the interpreting process of the material these categories were grouped into three broad thematic groups: counter-hegemony of the health sector within the movement, work in health and health education. With this organization was realized transversality in the category: In the course we learned how to deal and to value with the human being as a whole. It has been demonstrated as characteristic of the formation process of the MST a contraposition to a fragmented training courses still prevailing in the health area, which contributed to the understanding one of the main challenges in training professionals to work in SUS: to promote educational processes articulated with larger struggles of social movements, contributing to an unfragmented formation in which people are understood as historical, social and collective beings
Justicia distributiva e igualdad compleja en el pensamiento de Michael Walzer
No full textPartiendo de la concepción walzeriana de justicia distributiva, esta tesis trata de analizar, mostrar y desarrollar la aplicación práctica que la idea de igualdad compleja puede tener en diferentes sociedades. Es por esto por lo que se analiza como ideal regulativo que nos permita juzgar hasta qué punto una sociedad es justa y de qué forma podríamos intentar ir progresivamente acercándonos a ese ideal con el objetivo de configurar sociedades más justas, libres, plurales e igualitarias.
El trabajo se divide en dos partes: la primera de tipo fundacional, necesaria para poder seguir avanzando en la consecución de los objetivos propuestos y concerniente a los fundamentos filosóficos del pensamiento walzeriano. En el primer capítulo se analizan las diversas formas de hacer y acceder a la filosofía moral. Para ello, se ve cómo Walzer identifica tres modos, formas o senderos de hacer filosofía moral: descubrimiento, ya sea religioso o filosófico; invención, bien como una novedad o bien partiendo de determinados contextos; por último, Walzer analiza el modo interpretativo de llegar a la filosofía moral y por el cual se decanta. En el segundo capítulo se analiza en qué consiste la crítica social, cómo se hace ésta y desde qué posiciones se efectúa, con especial atención a la interpretación. En el tercer capítulo, se afronta la relación entre maximalismo y minimalismo moral, aclarando la concepción de mínimos morales que Walzer defiende en claro disenso respecto a otras propuestas. Para este fin, se analiza cuál es la relación de los mínimos y los máximos morales con la práctica de la crítica social y en general con respecto a la moralidad.
Respecto a la segunda parte de la tesis, queda enmarcada en la filosofía política walzeriana y discurre próxima a los conceptos de justicia distributiva e igualdad compleja, conceptos a los que se dedica un capítulo a cada uno y que desembocan en propuestas prácticas en torno a la idea de igualdad compleja. Por esta razón, primeramente, se considera el concepto de justicia distributiva, partiendo del contexto interpretativo diseñado en la parte anterior. Se analiza cómo la justicia distributiva parte de contextos morales maximalistas en los que los significados sociales de los bienes distribuidos son densos y requieren de interpretación. Además se indaga en las características de la teoría de los bienes walzeriana y se examina la relación entre el arte de la diferenciación y el concepto de justicia distributiva. A su vez, se advierte cómo la concepción de justicia distributiva genera una serie de resultados entre los que destaca la igualdad compleja que no es sino el producto de la diferenciación que se produce al dilucidar e interpretar los significados sociales de los bienes distribuidos.
Una vez entendido el desarrollo de la idea de justicia distributiva en Walzer y de qué forma nace la igualdad compleja se pasa al quinto y último capítulo en el que se desarrolla la aplicación práctica del concepto walzeriano de igualdad compleja, con el objetivo de solventar algunos de los problemas de justicia que hoy están presentes en las diferentes sociedades y que en pleno siglo XXI se hacen más sangrantes.
En este sentido, se trata de vislumbrar cómo a través de la idea igualdad compleja se puede evaluar y liberar a las diversas sociedades de ciertos males endémicos que las corroen como son la corrupción, la dominación de unos sobre otros, la distribución de bienes conforme a criterios, en ocasiones, más que dudosos, etc. Además en este intento, se vincula la idea de igualdad compleja con algunas propuestas de carácter discursivo, como la encabezada por Adela Cortina acerca de la democracia comunicativa y considerada de enorme utilidad para los objetivos propuestos
Test-beam results of a silicon pixel detector with Time-over-Threshold read-out having ultra-precise time resolution
No full textA time-tagging hybrid silicon pixel detector developed for beam tracking in the NA62 experiment has been tested in a dedicated test-beam at CERN with 10 GeV/c hadrons. Measurements include time resolution, detection efficiency and charge sharing between pixels, as well as effects due to bias voltage variations. A time resolution of less than 150 ps has been measured with a 200 μm thick silicon sensor, using an on-pixel amplifier-discriminator and an end-of-column DLL-based time-to-digital converter
Changes in educational assortative mating in contemporary Spain
No full textThis article analyses patterns and trends in educational assortative mating of the Spanish women born between 1920 and 1969 using data from the 2001 Spanish Census. By means of loglinear models we examine the following issues: i) intensity and changes in educational assortative mating patterns; ii) crossing barriers across educational thresholds and iii) degree of symmetry between male and female patterns. Results show that education matters in the composition of unions: people tend to marry assortatively according to their education. However this pattern clearly differs across cohorts and between educational groups, being higher for the extreme categories. The most notable trends are 1) the increasing intensity of homogamy among the more educated and 2) the incipient extinction of the traditional female hypergamic pattern.2001 Census, assortative mating, educational attainment, marriage, Spain
Search for Leptonic Decays of Dark Photons at NA62
No full textThe NA62 experiment at CERN, configured in beam-dump mode, has searched for dark photon decays in flight to electron-positron pairs using a sample of 1.4×1017 protons on dump collected in 2021. No evidence for a dark photon signal is observed. The combined result for dark photon searches in lepton-antilepton final states is presented and a region of the parameter space is excluded at 90% confidence level, improving on previous experimental limits for dark photon mass values between 50 and 600 MeV/c2 and coupling values in the range 10-6 to 4×10-5. An interpretation of the e+e- search result in terms of the emission and decay of an axionlike particle is also presented
Pulsed Production of Antihydrogen in AEgIS
No full textLow-temperature antihydrogen atoms are an effective tool to probe the validity of the fundamental laws of Physics, for example the Weak Equivalence Principle (WEP) for antimatter, and -generally speaking- it is obvious that colder atoms will increase the level of precision.
After the first production of cold antihydrogen in 2002 [1], experimental efforts have substantially progressed, with really competitive results already reached by adapting to cold antiatoms some well-known techniques pre- viously developed for ordinary atoms. Unfortunately, the number of antihydrogen atoms that can be produced in dedicated experiments is many orders of magnitude smaller than of hydrogen atoms, so the development of novel techniques to enhance the production of antihydrogen with well defined (and possibly controlled) conditions is essential to improve the sensitivity.
We present here some experimental results achieved by the AEgIS Collaboration, based at the CERN AD (Antiproton Decelerator) on the production of antihydrogen in a pulsed mode where the production time of 90% of atoms is known with an uncertainty of ~ 250 ns [2]. The pulsed antihydrogen source is generated by the charge-exchange reaction between Rydberg positronium (Ps*) and an antiproton (p¯): p¯ + Ps* → H¯* + e−, where Ps* is produced via the implantation of a pulsed positron beam into a mesoporous silica target, and excited by two consecutive laser pulses, and antiprotons are trapped, cooled and manipulated in Penning-Malmberg traps. The pulsed production (which is a major milestone for AEgIS) makes it possible to select the antihydrogen axial temperature and opens the door for the tuning of the antihydrogen Rydberg states, their de-excitation by pulsed lasers and the manipulation through electric field gradients.
In this paper, we present the results achieved by AEgIS in 2018, just before the Long Shutdown 2 (LS2), as well as some of the ongoing improvements to the system, aimed at exploiting the lower energy antiproton beam from ELENA [3]
Subjetividades, intersecções e implicações na pesquisa e intervenção ocupacional com mães adolescentes
No full textThis reflection article aims to answer the question: What are the implications, subjectivities and intersectionalities, from a feminist stance, present in the investigation and occupational intervention with adolescent mothers? For this purpose, the viewpoints of “Las Mercedes” (name that refers to adolescent mothers under State protection; their stories and life expe- riences) will be presented for dialogue, together with my own viewpoint as an occupational therapist as a researcher and intervener. The article addresses topics such as intersectionali- ties, ideas of employment and of being a woman, among other aspects, creating the challen- ge of the research/intervention from a decolonial posture in the hope that we can recogni- zing the subjectivities we have from being part of a system and, in this manner, discuss and cooperatively build knowledge under the light of the unveiled positionalities.Este artículo de reflexión pretende responder a la pregunta: ¿cuáles son, desde una postura feminista, las implicaciones, subjetividades e interseccionalidades presentes en la investi- gación y en la intervención ocupacional con madres adolescentes? Para tal fin, se pondrán en diálogo las posturas de Las Mercedes (nombre que encarna las madres adolescentes bajo protección del Estado, sus historias y vivencias) y las mías como terapeuta ocupacional, investigadora e interventora. El artículo logra abordar temas como las interseccionalidades, las ideas de trabajo y de ser mujer, entre otros aspectos, dejando como desafío la inter- vención desde una postura decolonial, en aras de reconocer nuestras subjetividades como parte de un sistema y así conversar y co-construir saberes a la luz de las posicionalidades develadas.A reflexão deste artigo objetiva responder à questão: quais são as implicações, subjeti- vidades e interseccionalidades presentes na pesquisa e na intervenção ocupacional com mães adolescentes em uma perspectiva feminista? Para isso, as posições de “Las Mercedes” (nome que se refere às mães adolescentes sob proteção do Estado, suas histórias e expe- riências) e as minhas, como terapeuta ocupacional, pesquisadora e intervencionista, serão postas em diálogo. O artigo propõe abordar questões como intersetorialidade, ideias de trabalho e ser mulher, dentre outros aspectos, deixando como desafio a intervenção, a par- tir de uma postura descolonial, a fim de reconhecer nossas subjetividades como parte de um sistema e, assim, conversar e co-construir conhecimento à luz das posições desveladas
First Full Beta-Strength Measurement With Dtas Across N=126 at Fair Phase-0
No full textAn experiment was performed at GSI with the objective of measuring theβ-intensity distribution in the decay of Hg, Au and Pt isotopes around N=126 using the total absorption gamma-ray spectroscopy technique. The aim is to benchmark theoretical models used to make predictions of half-life and neutron emission probabilities of exotic nuclei involved in the rapid neutron capture process, leading to the synthesis of very heavy elements. This paper presents some experimental details and the current status of the analysis
Observation of short range three particle correlations in e+ e- annihilations at LEP energies
No full textMeasurements are presented of short range three-particle correlations in e+e− annihilations at LEP using data collected by the DELPHI detector. At small values of the four-momentum difference, strong three-particle correlations are observed for like-sign (+++ and −−−) and for unlike-sign (++− and +−−) pion combinations which are not a consequence of two-particle correlations. A possible explanation of the observed effects in like-sign combinations is the existence of higher order Bose-Einstein interference, which significantly changes the particle distributions in jets
