Falhas de memória são comuns no cotidiano. Contudo, elas podem indicar ocorrências de problemas cognitivos, principalmente entre idosos. O artigo traz a tradução e a adaptação do Prospective and Retrospective Memory Questionnaire (PRMQ). O instrumento, no original constituído de 16 itens, avalia auto-relatos de falhas de memória prospectiva e retrospectiva. O estudo contou com 642 participantes, com idade variando entre 16 e 81 anos, recrutados em uma universidade e em grupos comunitários. A análise fatorial exploratória dos dados do PRMQ apontou a validade de construto apenas para oito itens. Então, optou-se por reconsiderar mais dois itens que apresentaram carga fatorial aceitável e compor uma escala de 10 itens, sendo cinco para cada dimensão da memória. A correlação para validade convergente e discriminante foi realizada com o Questionário de Percepção Subjetiva de Queixas de Memória para idosos (MAC-Q), em uma amostra de 38 participantes idosos, com idade média de 69 anos. O PRMQ-10 apresentou validade e confiabilidade (a = 0,80), com boas perspectivas para uso em pesquisa.
RESUMOA percepção de auto-eficácia geral em jovens e idosos serviu de base para o estudo das diferenças entre o auto-relato de falhas de memória prospectiva e retrospectiva. Uma amostra de 642 participantes, com idade entre 16 e 81 anos (26,62±13,89), respondeu ao Questionário Sociodemográfico, à Escala de Auto-eficácia Geral Percebida (EAEGP), e ao Questionário de Memória Prospectiva e Retrospectiva (PRMQ-10). De acordo com os resultados obtidos, auto-eficácia geral apresentou maior correlação com o auto-relato de falhas de memória prospectiva, enquanto idade e escolaridade correlacionaram com o auto-relato de falhas de memória retrospectiva. Como resultado adicional, verificou-se que existem pontos de reciprocidade entre auto-relato de falhas de memória e resultados de desempenho em tarefas de memória. Tais resultados assinalam maior vinculação entre as dimensões de auto-eficácia e a memória prospectiva. Palavras-chave: auto-eficácia; memória; auto-relato ABSTRACT Perception of self-efficacy and self-report of prospective and retrospective memory failuresThe general perception of self-efficacy in young and old people was taken as the basis for the study of the differences among self-reported prospective and self-reported retrospective memory. The participants were 642 aged between 16 and 81 years old (26,62±13,89), who have answered the Sociodemographic Questionnaire, the General Perception of Self-efficacy Scale (GPSES), and the Prospective and Retrospective Memory Questionnaire (PRMQ-10). Self-efficacy showed higher correlation with self-reported prospective memory failures while years of formal education and age correlated with self-reported retrospective memory failures. As a further result it was verified reciprocity between self-reported memory failures and performance in memory tasks, suggesting a strong association between the dimensions of self-efficacy and prospective memory.
This work is a semiotic phenomenological approach of writing in personal journal blogs to define and verify their potential as continuous and sustained movement toward personal change or self-innovation. The analysis juxtaposes, by quantitative and qualitative methods, chronological self-referential text data (semiotics) with the meaning of internal conversation disclosed in discourse (phenomenology). We take a specific blog domain for posts from random bloggers that would present self-referent terms as "I feel", "I think", "I believe", "my life", etc. Then we selected those posts with dense self-descriptions and expression of disparate personal thoughts and feelings. Approximately 150 posts were analyzed, resulting in a final sample of 12 homogeneous posts from a heterogeneous group of bloggers, nine females and three males, all native English speakers. We conclude that personal blog texts help convey psychological well-being through dialogical self-clarification, facilitate the emergence of new perspectives or self-actualizing, and can lead to self-innovation.Keywords: Blogs; Inner speech; Self-deliberation; Self-innovation. , como "eu sinto" "eu penso", "eu acredito", "minha vida" etc Resumo O presente trabalho recorre à fenomenologia semiótica para analisar diários pessoais em blogs com o objetivo de definir e verificar suas potencialidades como movimento contínuo e sustentado para mudanças pessoais e autoinovação. A análise justapõe, por métodos quanti e qualitativos, dados cronológicos e linguísticos de textos autorreferenciados (semiótica) com o sentido de conversas internas reveladas em discurso (fenomenologia). Foi tomado um domínio específico para postagens aleatórias de blogueiros que apresentassem termos autorreferentes
The modelling of wave-structure interaction (WSI) has significant applications in understanding natural processes as well as securing the safety and efficiency of marine engineering. Based on the technique of Computational Fluid Dynamics (CFD) and the opensource simulation framework -OpenFOAM, this paper provides a state-of-the-art review of WSI modelling methods. The review categorises WSI scenarios and suggests their suitable computational approaches, concerning a rigid, deformable or porous structure in regular, irregular, non-breaking or breaking waves. Extensions of WSI modelling for wave-structureseabed interactions and various wave energy converters are also introduced. As a result, the present review aims to help understand the CFD modelling of WSI and guide the use of OpenFOAM for target WSI problems.
