The importance of qualitative methodology in management empirical research

Purpose: The aim of this paper is to highlight the importance of qualitative research within the scope of management scientific studies, referring to its philosophy, nature and instruments. It also confronts it with quantitative methodology, approaching its differences as well as its complementariness and synergies, with the purpose of explaining, from a more analytic point of view, the relevance of qualitative methodology in the course of an authentic and real research despite its complexity. Design/methodology/approach: Regardless of its broad application, one may attest the scarcity literature that focuses on qualitative research applied to the management scientific area, as opposed to the large amount that refers to quantitative research. Findings: The paper shows the influence that qualitative research has on management scientific research. Originality/value:. Qualitative research assumes an important role within qualitative research by allowing for the study and analysis of certain types of phenomena that occur inside organisations, and in respect of which quantitative studies cannot provide an answer.

Multiple Linear Regression and Artificial Neural Networks to Predict Time and Efficiency of Soil Vapor Extraction

The prediction of the time and the efficiency of the remediation of contaminated soils using soil vapor extraction remain a difficult challenge to the scientific community and consultants. This work reports the development of multiple linear regression and artificial neural network models to predict the remediation time and efficiency of soil vapor extractions performed in soils contaminated separately with benzene, toluene, ethylbenzene, xylene, trichloroethylene, and perchloroethylene. The results demonstrated that the artificial neural network approach presents better performances when compared with multiple linear regression models. The artificial neural network model allowed an accurate prediction of remediation time and efficiency based on only soil and pollutants characteristics, and consequently allowing a simple and quick previous evaluation of the process viability.

Relatório de estágio em educação pré-escolar e ensino do 1º ciclo do ensino básico

O presente relatório – requisito parcial para obtenção do grau de mestre em Educação Pré-Escolar e Ensino do 1.º Ciclo do Ensino Básico – reflete as experiências e conhecimentos desenvolvidos, resultantes da prática pedagógica supervisionada desenvolvida em dois contextos de estágio: Educação Pré-Escolar e 1.º Ciclo do Ensino Básico. Com efeito, a estudante teve como objetivo descrever, compreender e refletir acerca do processo de prática segundo o desenvolvimento de capacidades e competências substanciais à prática docente. Enquanto (futura) profissional de educação, verifica-se pertinente a mobilização de saberes científicos, pedagógicos e culturais, adquiridos ao longo da formação inicial para que se torne exequível uma prática sustentada. Similarmente, o docente, baseando-se em quadros teóricos e concetuais (amplificados de forma subjetiva e continuada), desenvolverá a sua forma pessoal de pensar e agir nos contextos de práticas reais visando a inclusão e equidade educativas, e a colaboração profissional e reflexiva. Conforme a metodologia de investigação-ação (constituída por várias etapas interligadas – observação, planificação, ação e avaliação, reflexão), a ação da mestranda desenvolveu-se de forma cíclica e articulada, numa perspetiva construtivista – e holística – do conhecimento a erigir pelas crianças (atores centrais do processo) ressalvando-se, igualmente, a pertinência dos demais instrumentos orientadores elaborados no decorrer da ação. Concludentemente, os estágios desenvolvidos nos dois contextos facultaram a edificação de uma postura profissional, reflexiva e investigativa, promotora da tomada de decisões em contexto de prática reafirmando-se competências profissionais e pessoais e valorando-se, efetivamente, a formação ao longo da vida para aquele que se constitui um docente generalista.

Is mental practice an effective adjunct therapeutic strategy for upper limb motor restoration after stroke? A systematic review and meta- analysis

Stroke is one of the most common conditions requiring rehabilitation, and its motor impairments are a major cause of permanent disability. Hemiparesis is observed by 80% of the patients after acute stroke. Neuroimaging studies showed that real and imagined movements have similarities regarding brain activation, supplying evidence that those similarities are based on the same process. Within this context, the combination of mental practice (MP) with physical and occupational therapy appears to be a natural complement based on neurorehabilitation concepts. Our study seeks to investigate if MP for stroke rehabilitation of upper limbs is an effective adjunct therapy. PubMed (Medline), ISI knowledge (Institute for Scientific Information) and SciELO (Scientific Electronic Library) were terminated on 20 February 2015. Data were collected on variables as follows: sample size, type of supervision, configuration of mental practice, setting the physical practice (intensity, number of sets and repetitions, duration of contractions, rest interval between sets, weekly and total duration), measures of sensorimotor deficits used in the main studies and significant results. Random effects models were used that take into account the variance within and between studies. Seven articles were selected. As there was no statistically significant difference between the two groups (MP vs control), showed a - 0.6 (95% CI: -1.27 to 0.04), for upper limb motor restoration after stroke. The present meta-analysis concluded that MP is not effective as adjunct therapeutic strategy for upper limb motor restoration after stroke.
