Comportamentos de cidadania organizacional em educadores de infância da rede pública e privada

Several studies have identified the nature and characteristics of organizational citizenship behaviors (OCB) in primary and secondary education teachers, but research in the field of preschool education is almost non-existent. Empirical evidence of the impact that this type of behavior has on the functioning of any organization and the particularities of the roles of preschool teachers in relation to those of other teachers, justify conducting studies on this topic with early childhood education professionals. This paper presents the conclusions of a qualitative study carried out with public and private preschool teachers. The organizational citizenship behaviors performed by these professionals are identified, as well as personal and contextual factors that influence them. The data was collected in interviews with preschool teachers and was analyzed following the Grounded Theory procedures, in particular the constant comparison technique (Glaser & Strauss, 1967). In a second moment, the data was discussed with different participants in a focus group. Data analysis indicates that although preschool teachers tend to view most of the activities they develop as central dimensions of their specific professionality, therefore not describing them as OCBs, it is possible to identify some forms of OCBs specific to preschool teachers, either at the professional level (pedagogical and/or organizational) and at the interpersonal level (activities focused on the relationship with children and families). Major divergences were identified in the dimension of providing care.info:eu-repo/semantics/publishedVersio

Caracterização agronômica de acessos de cevada de alta produtividade sob irrigação no Cerrado

O objetivo deste trabalho foi estimar parâmetros genéticos, fenotípicos e ambientais de 113 acessos de cevada (Hordeum vulgare), previamente selecionados com base em alta produtividade, em sistema de produção irrigado no Cerrado, para uso em programas de melhoramento no Brasil. O experimento foi realizado em 2013, em dois locais no Distrito Federal, tendo-se utilizado o delineamento experimental de blocos ao acaso, com três repetições. Avaliaram-se as características: rendimento de grãos, classificação comercial de primeira, peso de mil grãos, altura de plantas, acamamento e dias para espigamento. Foram observadas diferenças significativas entre ambientes e acessos para todas as características avaliadas, além de interação genótipo x ambiente. Os acessos MCU 3832 PI 402310, MCU 3484 PI 401962, CI 08053 Custer, MCU 3634 PI 402112 e MCU 3816 PI 402294 destacaram-se em relação ao rendimento de grãos e à classificação comercial de primeira. É possível obter altos ganhos de seleção com altos valores de herdabilidade. No entanto, a seleção indireta não é recomendada nas condições experimentais, em razão das baixas correlações genotípicas e fenotípicas obtidas. Também é possível a seleção simultânea de acessos de cevada com alto rendimento e ciclo de espigamento precoce, fator decisivo no processo de escolha de genótipos para futuros experimentos. Os acessos colombianos são os mais adaptados às condições de Cerrado.The objective of this work was to estimate the genetic, phenotypic, and environmental parameters of 113 barley accessions (Hordeum vulgare), previously selected based on high yield, in an irrigated production system in the Cerrado (Brazilian savanna), for use in breeding programs in Brazil. The experiment was conducted in 2013 at two sites in the Federal District, using a randomized complete block design with three replicates. The evaluated traits were: grain yield, kernel plumpness, thousand grain weight, plant height, lodging, and days to heading. Significant differences were observed between environment and accessions for all studied traits, as well as genotype x environment interaction. The MCU 3832 PI 402310, MCU 3484 PI 401962, CI 08053 Custer, MCU 3634 PI 402112, and MCU 3816 PI 402294 accessions stood out regarding grain yield and kernel plumpness. It is possible to obtain high selection gains with high heritability values. However, indirect selection is not recommended in the experimental conditions due to the low genotypic and phenotypic correlations obtained. It is also possible to select barley accessions with high yield and early heading date simultaneously, an important factor in the genotype selection process for future experiments. The accessions from Colombia are the most adapted to the Cerrado conditions

Genetic parameters and agronomic characterization of elite barley accessions under irrigation in the cerrado

There is a demand for barley cultivars that are suitable for the malt industry as well as genotypes that are stable and better adapted for irrigation in the Cerrado. This study aimed to estimate the genetic parameters by assessing 69 barley genotypes from different countries, from 2012 to 2014, under irrigation in the Cerrado. Six agronomic characteristics were assessed: grain yield, plumpness kernel, thousand seeds weight, plant height, degree of plant lodging and days to heading. Analysis of variance, cluster test and phenotypic, genotypic and environmental correlations were performed. Significant effects were observed for genotypes, years and the G x E interaction. High values of broad-sense heritability (> 86%) were found for all the characteristics, which enabled direct selection. The Colombian accession MCU363PI402112 stood out for its agronomic characteristics. Genotype selection based on the phenotypic evaluations was possible due to their good experimental accuracy and precision. Precocious genotypes with high grain yields and homogeneous grain sizes were selected. Due to the environmental influence on the grain yield, additional studies concerning the components of yield in this environment are necessary to facilitate the selection of more productive genotypes

Evaluation of Some Physical and Health Parameters in a Local Physical Activity Program for Seniors

Background: About 1/5 of the population of Évora Municipality in Portugal is aged 65 and over, and there has been a continued deterioration in the ageing index (159 in 2016). Évora City Hall offers the Active Seniors program which aims to promote physical activity and healthy lifestyles among older adults (at least 55 years). This study aims to evaluate the effect on some physical and medical parameters of the participants in this program within a period of 6–12 months, showing why it is worthwhile for the municipalities to elect this type of programs. Methods: A 1-year follow-up of three groups of seniors was conducted that covered participants enrolled for the first time in the Active Seniors program and individuals who had participated in the Active Seniors program in previous years and who would maintain or increase the number of sessions per week. Participants self-reported sociodemographic and past health information and were submitted to medical tests, and anthropometric and physical evaluations. Differences in medical and physical parameters were evaluated using analysis of covariance and mixed models. Results: In just 6 months, seniors who participated in the Active Seniors program for the first time improved several medical tests results and improved their performance in physical fitness tests (all p < 0.05). The increase in the number of sessions per week decreased the systolic blood pressure values after only 6 months (p < 0.001) and improved the physical fitness tests over 12 months (p < 0.05). Conclusions: The Active Seniors program is an effective way to improve the health and physical fitness of older adults. The continuation of the program, with or without the increase in the number of weekly sessions, allows controlling the medical parameters and increasing the functional fitness of the participants. © 2019 The Author(s).

A Câmara Municipal de Évora oferece o programa Seniores Ativos que visa promover a atividade física e estilos de vida saudáveis junto dos adultos com pelo menos 55 anos. Este estudo visa avaliar o efeito em alguns parâmetros físicos e médicos com a participação neste programa ao longo de 6 e 12 meses, procurando também mostrar que vale a pena que os municípios apostem nesse tipo de programas. Métodos: Durante 12 meses foram seguidos três grupos de adultos, com 55 ou mais anos, que abrangiam indivíduos que participavam pela primeira vez neste programa e indivíduos que já participavam no programa Seniores Ativos em anos anteriores e que iriam manter ou aumentar o número de sessões por semana. Os participantes forneceram informações sociodemográficas e do seu estado de saúde, e foram submetidos a exa­mes médicos e a avaliações antropométricas e físicas. As diferenças nos parâmetros médicos e físicos foram avaliadas usando testes paramétricos e não paramétricos, análise de covariância e modelos mistos. Resultados: Em apenas 6 meses, os seniores que participaram pela primeira vez no programa Seniores Ativos melhoraram os resultados dos seus testes médicos e melhoraram o seu desempenho em todos os testes de aptidão física (todos p < 0.05). O aumento do número de sessões por semana originou uma diminuição do valor da pressão sanguínea sistólica em apenas 6 meses (p < 0.001) e uma melhoria nos resultados dos testes de aptidão física ao longo dos 12 meses (p < 0.05). Conclusões: O programa Seniores Ativos é um meio eficaz para melhorar a saúde e a aptidão física dos idosos. A permanência no programa, com ou sem aumento no número de sessões semanais, permite controlar os parâmetros médicos e melhorar a aptidão funcional dos participantes

E. Globulus Vessel and Fibre Chemical Analysis

Hardwood species have a complex cellular structure consisting of fibres, vessel elements and parenchyma cells with different chemical compositions. However, the presence of vessels with significant dimensions in their structure is a recurrent problem in the operation of industrial UWF paper printing. Since the 1980s, vessel picking and ink refusal are problems that paper professionals have tried to solve, but solutions for these have not yet been fully found. If vessels are concentrated in a stream, they can be pre-treated (e.g., by mechanical refining) and reincorporated into the pulp. Other strategies aim at vessel enzymatic and/or chemical passivation and sheet surface chemical treatment, altering the vessel adhesion to the fibre network. This requires vessel concentration at laboratorial level for proper chemical studies, such as FE-SEM, μ-XPS, TOF-SIMS and μFTIR. The main objective of our experimental study was to examine bleached kraft pulp E. globulus vessel and fibre composition. For this we performed EDX and μ-FTIR analysis on both fibre and vessel elements, and obtained the carbohydrate composition, the total acids content, the hexenuronic acids content and the zeta potential. Keywords: E. globulus, vessel, EDX, μ-FTIR, sugar content, zeta potentia

Ozone and UVC radiation as disinfection strategies of textile substrates

The emergence of COVID-19 triggered changes in routines and other concerns, such as the disinfection of textile clothing, to avoid the transmission of the disease. The application of ozone and UV radiation to textiles are interesting disinfection methodologies that do not use harmful chemicals. Ozone has been used for several years as a disinfectant, and UVC radiation has been shown to destroy viruses and bacteria. These technologies can be applied in hospitals, clinics, clothing stores, hotels, among others. This study aimed to investigate the impact of ozone (at different concentrations) and UVC radiation treatments and their combination (at different treatment times) in the elimination of pathogenic microorganisms (Acinetobacter ESB260 and Escherichia coli ATCC 8739) applied to different textile substrates. These treatments were applied in a prototype of the MTEX PHYS Sterilizer. The results demonstrated that ozone is more effective than UVC radiation. The highest bacterial inactivation with UVC radiation was that lasting 60 minutes. The best results with ozone treatments were obtained at concentrations of 50 and 60 ppm for 60 minutes, and log reductions of up to 5 log cycles were obtained. Apparently, the treatment time is more relevant than the ozone concentration. The combined treatment triggered a synergy of the treatments, in which values of logarithmic reduction were identical to those of the ozone treatment, but in a shorter time. The effectiveness of the treatments depends on the type of fabric and the bacterial species/strain.info:eu-repo/semantics/publishedVersio

Percepção de fisioterapeutas sobre facilitadores e barreiras no uso de diferentes ferramentas para treinamento resistido em pacientes com DPOC: estudo de método mistos

O objetivo do estudo foi quantificar e analisar qualitativamente a percepção de fisioterapeutas sobre facilitadores e barreiras no uso de diferentes ferramentas para treinamento resistido em pacientes com doença pulmonar obstrutiva crônica (DPOC). O método utilizado foi desenvolvido em um centro de reabilitação. Seis fisioterapeutas que participaram como terapeutas de um ensaio clínico randomizado foram entrevistados. O protocolo consistiu na avaliação de três ferramentas para treinamento resistido: tubos elásticos, bandas elásticas e treinamento convencional com equipamentos de musculação. Depois da finalização do ensaio clínico randomizado, os fisioterapeutas foram convidados a participar de um grupo focal para análise qualitativa e responder questionário fechado para análise quantitativa. Os profissionais opinaram sobre vantagens e desvantagens de cada uma das três ferramentas na prática clínica. A análise do grupo focal resultou em oito temas: insegurança em relação à carga e manuseio das ferramentas; implementação de tratamento domiciliar; melhorias para ferramentas; vantagens e desvantagens das ferramentas; incidência de lesões com ferramentas elásticas; preferência dos pacientes; e particularidades de cada ferramenta. Fisioterapeutas apontaram diferentes barreiras e facilitadores para o treinamento resistido. Características das ferramentas – como custo, portabilidade, manuseio, praticidade e percepção do paciente e fisioterapeuta – foram citadas como fatores que influenciam a prática clínica. Na análise quantitativa, nenhuma diferença foi observada quando comparados os escores para cada instrumento. As três ferramentas são aplicáveis na prática clínica do fisioterapeuta. Adicionalmente, as características e particularidades de cada uma delas devem ser consideradas.This study sought to quantify and qualitatively analyze the perception of physical therapists about facilitators and the challenges in the use of different types of tools for resistance training in chronic obstructive pulmonary disease (COPD) patients. This was a mixed-model study with qualitative analysis developed in a rehabilitation center. Six physical therapists who performed a randomized clinical trial were interviewed. The protocol consisted of the evaluation of three types of resistance training: elastic tubes, elastic bands, and training with conventional weight machines. After completion of the randomized trial, therapists were invited to participate in a focus group to collect qualitative data. Physical therapists also answered a quantitative questionnaire containing closed questions. The main outcome measures were the opinion of physical therapists about the advantages and disadvantages in clinical practice of each of the analyzed tools. The focus group analysis resulted in eight themes: Insecurities regarding load and handling tools, implementation of home-based treatment, improvements of tools, advantages and disadvantages of tools, incidence of injuries with elastic tools, patient’s preferences, and particularities of the tools. Physical therapists pointed out different challenges and facilitators for resistance training. Characteristics of the tools such as costs, portability, handling and practicality were cited as factors that influence clinical practice. In the quantitative analysis, no differences were observed when comparing the scores of each instrument. The three tools analyzed are applicable and feasible in the clinical practice of physical therapists; moreover, they present different characteristics and particularities that should be considered, such as cost, clinical applicability, portability and perception of the patient and therapists.El objetivo del estudio fue cuantificar y analizar cualitativamente la percepción de fisioterapeutas sobre facilitadores y barreras en el uso de diferentes herramientas de entrenamiento de resistencia en pacientes con enfermedad pulmonar obstructiva crónica (EPOC).
