SINTOMAS DE BURNOUT EM PROFISSIONAIS DE ENFERMAGEM E SUA CORRELAÇÃO COM REAJUSTAMENTO SOCIAL E CONDIÇÕES DE TRABALHO

O presente estudo teve como principal objetivo correlacionar escalas psicométricas em trabalhadores da área de enfermagem de um Hospital de grande porte do Sudoeste do Paraná. Foram aplicados os seguintes instrumentos: Maslach Burnout Inventory General Survey em suas três dimensões envolvimento pessoal do trabalho, despersonalização e exaustão emocional, os inventários IDATE TRAÇO e IDATE ESTADO, a escala de Reajustamento Social de Holmes e Rahe, além de um Inventário Específico de Eventos de Enfermagem que fora construído de forma experimental para a aplicação na amostra pesquisada. Foram abordados 240 profissionais da área de enfermagem no respectivo ambiente de pesquisa, obtiveram-se um n=192 sujeitos. Como resultados expressivos encontraram-se uma correlação de Pearson entre a Escala de Maslach e suas três dimensões, além do Inventário IDATE ESTADO correlacionado com a Escala de Reajustamento Social. Considerou-se ainda que existiu uma correlação entre o Inventário IDATE ESTADO e um Escore Combinado no programa estatístico empregado na tabulação dos dados coletados. Concluiu-se neste estudo que fatores de reajustamento social podem influenciar positiva ou negativamente em estados de ansiedade em trabalhadores da área de enfermagem hospitalar, considerando ainda as três dimensões avaliadas pelo Maslach Burnout Inventory.

Critical noise levels for LDPC decoding

We determine the critical noise level for decoding low density parity check error correcting codes based on the magnetization enumerator , rather than on the weight enumerator employed in the information theory literature. The interpretation of our method is appealingly simple, and the relation between the different decoding schemes such as typical pairs decoding, MAP, and finite temperature decoding (MPM) becomes clear. In addition, our analysis provides an explanation for the difference in performance between MN and Gallager codes. Our results are more optimistic than those derived via the methods of information theory and are in excellent agreement with recent results from another statistical physics approach.

Using LatCrit, Autoethnography, and Counterstory to Teach About and Resist Latina/o Nihilism

Nihilism caused by inequalities and injustices hurts students of color. Educators can help these students with Critical Race theory and storytelling. Latina/o students also face nihilism but there is no clear solution. This study explores a way to use LatCrit in the K-12 classroom to fight for justice and equality.

The role of exploration and critical decision making and problem solving in making life choices

Although the literature on the types of abilities and processes that contribute to identity formation has been growing, the research has been mainly descriptive/correlational. This dissertation conducted an experimental investigation of the role of two theoretically distinct processes (exploration and critical problem solving) in identity formation, one of the first to be reported. The experimental training design (pre-post, training versus control) used in this study was intended to promote identity development by fostering an increase in the use of exploration and critical problem solving with respect to making life choices. Participants included 53 psychology students from a large urban university randomly assigned to each group. The most theoretically significant finding was that the intervention was successful in inducing change in the ability to use critical skills in resolving life decisions, as well as effecting a positive change in identity status.

Global compilation of benthic data sets I

Approaches to quantify the organic carbon accumulation on a global scale generally do not consider the small-scale variability of sedimentary and oceanographic boundary conditions along continental margins. In this study, we present a new approach to regionalize the total organic carbon (TOC) content in surface sediments (<5 cm sediment depth). It is based on a compilation of more than 5500 single measurements from various sources. Global TOC distribution was determined by the application of a combined qualitative and quantitative-geostatistical method. Overall, 33 benthic TOC-based provinces were defined and used to process the global distribution pattern of the TOC content in surface sediments in a 1°x1° grid resolution. Regional dependencies of data points within each single province are expressed by modeled semi-variograms. Measured and estimated TOC values show good correlation, emphasizing the reasonable applicability of the method. The accumulation of organic carbon in marine surface sediments is a key parameter in the control of mineralization processes and the material exchange between the sediment and the ocean water. Our approach will help to improve global budgets of nutrient and carbon cycles.

Vertical profiles of environmental parameters measured on discrete water samples collected with Niskin bottles at station TARA_132 during the Tara Oceans expedition 2009-2013

The Tara Oceans Expedition (2009-2013) was a global survey of ocean ecosystems aboard the Sailing Vessel Tara. It carried out extensive measurements of evironmental conditions and collected plankton (viruses, bacteria, protists and metazoans) for later analysis using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set includes properties of seawater, particulate matter and dissolved matter that were measured from discrete water samples collected with Niskin bottles during the 2009-2013 Tara Oceans expedition. Properties include pigment concentrations from HPLC analysis (10 depths per vertical profile, 25 pigments per depth), the carbonate system (Surface and 400m; pH (total scale), CO2, pCO2, fCO2, HCO3, CO3, Total alkalinity, Total carbon, OmegaAragonite, OmegaCalcite, and dosage Flags), nutrients (10 depths per vertical profile; NO2, PO4, N02/NO3, SI, quality Flags), DOC, CDOM, and dissolved oxygen isotopes. The Service National d'Analyse des Paramètres Océaniques du CO2, at the Université Pierre et Marie Curie, determined CT and AT potentiometrically. More than 200 vertical profiles of these properties were made across the world ocean. DOC, CDOM and dissolved oxygen isotopes are available only for the Arctic Ocean and Arctic Seas (2013).

Revisión sistemática y metanálisis del rendimiento diagnóstico de los hallazgos ecográficos componentes del sonograma genético realizado en el segundo trimestre de gestación para la detección de Síndrome de Down

El impacto que tienen los defectos congénitos sobre la salud de las personas afectadas, sus familias y sobre la sociedad en su conjunto es muy considerable. En España se estima que existe una prevalencia de anomalías cromosómicas hasta 2010 de 1,49% de los recién nacidos vivos. El Síndrome de Down (SD) es la tercera causa de defecto congénito y la primera de cromosomopatía, con una prevalencia de 23 por cada 10000 nacidos vivos. La importante morbilidad asociada en los individuos con síndrome de Down se acompaña de un alto coste económico, estimándose en 329750,63 euros por cada nuevo caso, constituyendo un cargo a lo largo de la vida de 1316 millones de euros. Por todo ello, la detección de esta alteración es la indicación más frecuente de diagnóstico prenatal invasivo. Las pruebas invasivas, como amniocentesis, biopsia de vellosidades coriales y cordocentesis, se asocian con un aumento del 1% del riesgo de aborto y, por tanto, sólo se realizan cuando se considera que hay una probabilidad elevada de que el feto tenga un defecto cromosómico, siendo por tanto fundamental una buena selección del grupo de gestantes de alto riesgo...

Human rhinovirus-induced inflammatory responses are inhibited by phosphatidylserine containing liposomes

Human rhinovirus (HRV) infections are major contributors to the healthcare burden associated with acute exacerbations of chronic airway disease, such as chronic obstructive pulmonary disease and asthma. Cellular responses to HRV are mediated through pattern recognition receptors that may in part signal from membrane microdomains. We previously found Toll-like receptor signaling is reduced, by targeting membrane microdomains with a specific liposomal phosphatidylserine species, 1-stearoyl-2-arachidonoyl-sn-glycero-3-phospho-L-serine (SAPS). Here we explored the ability of this approach to target a clinically important pathogen. We determined the biochemical and biophysical properties and stability of SAPS liposomes and studied their ability to modulate rhinovirus-induced inflammation, measured by cytokine production, and rhinovirus replication in both immortalized and normal primary bronchial epithelial cells. SAPS liposomes rapidly partitioned throughout the plasma membrane and internal cellular membranes of epithelial cells. Uptake of liposomes did not cause cell death, but was associated with markedly reduced inflammatory responses to rhinovirus, at the expense of only modest non-significant increases in viral replication, and without impairment of interferon receptor signaling. Thus using liposomes of phosphatidylserine to target membrane microdomains is a feasible mechanism for modulating rhinovirus-induced signaling, and potentially a prototypic new therapy for viral-mediated inflammation.

Time-series of snow spectral albedo and superficial snow specific surface area at Dome C in Antarctica, 2012-2015

Spectral albedo has been measured at Dome C since December 2012 in the visible and near infrared (400 - 1050 nm) at sub-hourly resolution using a home-made spectral radiometer. Superficial specific surface area (SSA) has been estimated by fitting the observed albedo spectra to the analytical Asymptotic Approximation Radiative Transfer theory (AART). The dataset includes fully-calibrated albedo and SSA that pass several quality checks as described in the companion article. Only data for solar zenith angles less than 75° have been included, which theoretically spans the period October-March. In addition, to correct for residual errors still affecting data after the calibration, especially at the solar zenith angles higher than 60°, we produced a higher quality albedo time-series as follows: In the SSA estimation process described in the companion paper, a scaling coefficient A between the observed albedo and the theoretical model predictions was introduced to cope with these errors. This coefficient thus provides a first order estimate of the residual error. By dividing the albedo by this coefficient, we produced the "scaled fully-calibrated albedo". We strongly recommend to use the latter for most applications because it generally remains in the physical range 0-1. The former albedo is provided for reference to the companion paper and because it does not depend on the SSA estimation process and its underlying assumptions.
