- O professor num contexto de liderança : valores, liderança e influência no ensino superior civil militarPublication . Ribeiro, Ana Catarina Carvalho Gomes da Silva Napierala; Ilharco, Fernando Albano Maia de MagalhãesApesar de ter surgido como um tema específico para as organizações empresariais, políticas e militares, a liderança contempla atualmente cada vez mais áreas, adaptando-se em larga escala ao quotidiano. Uma das áreas onde os conceitos e teorias de liderança têm sido aplicados é a educação. A figura do gestor das escolas, que é normalmente um professor com alguma experiência, tem sem dúvida um papel de destaque, pois lidera determinada instituição escolar. Este, através do seu exemplo, pode demonstrar o tipo de clima organizacional que pretende ter na sua instituição. Paralelamente, o professor também se encontra numa posição de influência sobre os alunos, através dos seus comportamentos e forma de comunicar. Desta forma, algumas teorias de liderança podem aconselhar e/ou explicar a eficácia de determinados comportamentos no contexto de sala de aula, com o objetivo de melhorar a sua performance enquanto transmissor de conhecimentos importantes para a formação do aluno e também enquanto educador, levando os alunos a atingirem os objetivos propostos com satisfação e empenho. Como exemplo ilustrativo da influência que o professor pode ter nos seus alunos, esta investigação apresenta um estudo realizado em duas instituições de ensino universitário, inquirindo professores e alunos acerca dos valores morais que ambos consideram mais importantes para que haja um clima que favoreça o ensino e, consequentemente, um bom funcionamento da sala de aula.
- Innovation by patients with rare diseases and chronic needsPublication . Oliveira, Pedro; Zejnilovic, Leid; Canhão, Helena; Hippel, Eric VonWe provide the first empirical exploration of disease-related innovation by patients and their caregivers. Our aims were to explore to what degree do patients develop innovative solutions; how many of these are unique developments; and do these solutions have positive perceived impact on the patients' overall quality of life? In addition, we explored the factors associated with patient innovation development, and sharing of the solutions that the patients developed. Methods: We administered a questionnaire via telephone interviewing to a sample of 500 rare disease patients and caregivers. The solutions reported were pre-screened by the authors for their fit with the self-developed innovation aim of the study. All the reported solutions were then validated for their novelty by two medical professionals. Logistic regression models were used to test the relationships between our key variables, patient innovation and solution sharing. Results: 263 (53%) of our survey respondents reported developing and using a solution to improve management of their diseases. An initial screening removed 81 (16%) solutions for being an obvious misfit to the self-developed innovation aim of the study. This lowered the sample of potentially innovative solutions to 182 (36%). Assessment of novelty and usefulness of the solutions, conducted by two medical evaluators, confirmed that 40 solutions (8%) were indeed novel, while the remaining 142 (28%) were already known to medicine. The likelihood of patient innovation increased as the education level increased (OR 2, p < 0.05), and as their perception of limitations imposed by their disease increased (OR 1.3, p < 0.05). 55 individuals diffused their solutions to some degree, with 50 of these sharing via direct diffusion to other patients. There is a positive relationship between the impact of a solution on the respondents' overall quality of life and likelihood of solution sharing. Conclusions: Given that hundreds of millions of people worldwide are afflicted by rare diseases, patient and their caregivers can be a tremendous source of innovation for many who are similarly afflicted. Our findings suggest that many patients could be greatly assisted by improved diffusion of known solutions and best practices to and among patients and their caregivers.
