ABSTRACT
Pesquisas sobre gratidão têm se mostrado cada vez mais frequentes, sobretudo, devido às suas relações com o bem-estar. O objetivo desta pesquisa foi adaptar e buscar evidências de validade para o Brasil de uma medida de gratidão, o Gratitude Questionnaire. Foram realizados procedimentos controlados de tradução e aplicou-se o instrumento em 916 adultos, média de idade de 37 anos, predominantemente com ensino superior completo. Os resultados revelaram adequação dos dados à estrutura de um fator do instrumento, com adequada consistência interna e itens altamente discriminativos. As correlações entre gratidão e demais variáveis mostraram-se de acordo com o esperado teoricamente: positivas com autoestima, otimismo, satisfação de vida e afeto positivo. A gratidão ainda explicou o bem-estar subjetivo para além dos fatores de personalidade. O instrumento mostrou satisfatórias evidências de validade no contexto brasileiro, contudo, observou-se que ele carece de itens que cubram o espectro mais alto do traço latente. (AU)
Studies on gratitude are becoming increasingly frequent, mainly because of its relationship with well-being. The aim of this study was to adapt an instrument of gratitude, the Gratitude Questionnaire, and to seek evidence of its validity for Brazil. Controlled translation procedures were performed, and the instrument was applied to 916 adults, mean age 37 years, predominantly with higher education level. The results revealed adequacy of the data for a single factor structure of the instrument, with satisfactory reliability, and highly discriminative items. The correlations between gratitude and other variables were as theoretically expected: Positive with self-esteem, optimism, life satisfaction, and positive affect. Gratitude also explained subjective well-being beyond personality factors. The instrument showed satisfactory evidence of validity in the Brazilian context; however, it was observed that it lacks items that cover the higher spectrum of the latent trait. (AU)

After the progress made during the genomics era, bioinformatics was tasked with supporting the flow of information generated by nanobiotechnology efforts. This challenge requires adapting classical bioinformatic and computational chemistry tools to store, standardize, analyze, and visualize nanobiotechnological information. Thus, old and new bioinformatic and computational chemistry tools have been merged into a new sub-discipline: nanoinformatics. This review takes a second look at the development of this new and exciting area as seen from the perspective of the evolution of nanobiotechnology applied to the life sciences. The knowledge obtained at the nano-scale level implies answers to new questions and the development of new concepts in different fields. The rapid convergence of technologies around nanobiotechnologies has spun off collaborative networks and web platforms created for sharing and discussing the knowledge generated in nanobiotechnology. The implementation of new database schemes suitable for storage, processing and integrating physical, chemical, and biological properties of nanoparticles will be a key element in achieving the promises in this convergent field. In this work, we will review some applications of nanobiotechnology to life sciences in generating new requirements for diverse scientific fields, such as bioinformatics and computational chemistry.
