Inteligibilidade e Mediatismo

Neste artigo, dividido em duas partes, discute-se a validade, e a possibilidade, do discurso científico num contexto governado pelo mediatismo e imediatismo da comunicação. Na primeira parte é feito um breve excurso a propósito de questões epistemológicas. Na segunda parte, através de um exercício de natureza empírica, procura demonstar-se que a excessiva mediatização da informação impede uma visão criteriosa e fundamentada dos acontecimentos, ou seja, impede, mesmo em contexto académico, uma narrativa minimamente científica.info:eu-repo/semantics/publishedVersio

La moltiplicazione del melo con la tecnica della micropropagazione. Variazione del pH in substrati diversi durante la fase di moltiplicazione

10 páginas, 2 figuras, 5 tablas, 9 referencias.-- Esta revista es continuación de Rivista della Societa Toscana di Orticoltura y continuada por Advances in horticultural science.I numerosi studi condotti in questi ultimi 20 anni sulla applicazione della coltura in vitro a diverse specie coltivate, hanno focalizzato principalmente la messa a punto dei terreni nutritivi, il ruolo dei fitoregolatori nelle diverse fasi di crescita ed il controllo ormonale sulla morfogenesi. Quasi del tutto trascurata, come appare dai lavori riportati in bibliografia, sono state invece le indagini su altri fattori che probabilmente esercitano un ruolo di primo piano sulla crescita e sui processi morfogenetici che avvengono in vitro.Peer reviewe

Forecasting the risk of WRMSDs in home care nurses

Studies regarding work related musculoskeletal disorders (WRMSDs) in nurses have been carried out mostly in hospitals or in other institutional contexts. Information about this theme in providing home-based care is scarce. The main goals of this work are the characterization of musculoskeletal complaints in nurses who work at the Health Centers of the northern Portugal and that provide home-based care, the identification of the main risk factors present in the homecare context and the development of statistical models to forecast the risk in the same context. The principal methodology used in this work was a questionnaire developed in electronic format which was based on the “Standardized Nordic Questionnaire” for the analysis of musculoskeletal symptoms. It were used univariate models of binary logistic regression to estimate the risk of WRMSDs present in the practice of home-based care and also to assess which risk factors that could contribute to the appearance of complaints in the lumbar region in the professionals who provide homecare. The body areas with more musculoskeletal complaints are the back and the shoulders. The nurses who provide home care have nearly triple chance of having musculoskeletal complaints in the lumbar region than their counterparts of Health Centers (OR=3.19 (p<0.05), 95% Confidence Interval [1.26; 8.08]). We obtained various statistical models for forecast the risk of having low back complaints in home care nurses. From all of them was selected the one that presented more stability and reliability. The model performance was evaluated by ROC (Receiver Operating Characteristic) analysis yielding a value for the area under the ROC curve of 0.889 (p<0.05). This value reveals a high discriminating power, that is, the model is able to correctly forecast the complaints in the lumbar region in 88.9% of cases

Work-related musculoskeletal disorders in home care nurses: study of the main risk factors

BACKGROUND: Nurses are a risk group for work-related musculoskeletal disorders (WMSDs). Several studies reveal that nurses have high prevalence rates of injuries and symptoms related to WMSDs. However, many of these studies focus mostly on hospital nurses. Worldwide, few studies include home care nurses. Objective This work aimed to identify the body region most affected by musculoskeletal complaints in home care nursing, and subsequently develop a statistical model, that includes the main risk factors, to predict the risk of having musculoskeletal complaints in the identified region. Methods The research method was based on the Standardised Nordic Questionnaire applied to home care nurses working at Health Centres of northern Portugal. Univariate and multivariate models of logistic regression were used to meet the goals of this work. Results Home care nurses have a three times greater chance of having lumbar complaints than their counterparts working only at Health Centres (OR = 3.19 (p < 0.05), with a 95% confidence interval [1.256; 8.076]). A statistical model with seven variables (forearm posture; static postures; arm posture; arm supported; bed height; job satisfaction; assistive devices) was obtained to predict lumbar complaints. Conclusions The lumbar region was identified as the most affected by musculoskeletal complaints. These complaints were associated with seven factors.This work was financed by National Funds - Portuguese Foundation for Science and Technology, under UID/CEC/00319/2013.info:eu-repo/semantics/publishedVersio

Musculoskeletal disorders in nurses who provide home care

Work related musculoskeletal disorders (WRMSDs) have been described as the most important occupational health problem tormenting the nursing workers. This work demonstrated a preliminary analysis on the evaluation of responses to a questionnaire based on one developed by Kuorinka and colleagues. Main goal of this work is the characterisation and evaluation of the risk of WRMSDs on the home care nursing. The first results reveal that a great percentage of the respondents provide home care. The most frequent complaints are in spine and shoulders. There are no significant association between the related disorders and the home car
