Efeitos de tarefas cognitivas no controle postural de idosos: Uma revisão sistemática

Demanding attention in order to keep postural balance increases with aging and with the presence of concurrent tasks that require information processing. Several studies have demonstrated that motor performance can be related to the complexity of the task and aging process, presenting a possible interaction between these factors. The aim of this review was to identify and analyze published papers about the effects of cognitive tasks on the postural control of elderly individuals. A systematic search in the Web of Science, SportDiscus, CINAHL, Science Direct on line, Biological Abstracts, PsycINFO, and Medline databases was made and 444 articles were found. Eight were selected that studied the variables of interest. These studies showed that postural control seems to be influenced by the individual's attention processes and that deficits in such ability may be associated to an increased risk of falls. © FTCD/CIDESD.

Multivariate models for correlated count data

In this study, we deal with the problem of overdispersion beyond extra zeros for a collection of counts that can be correlated. Poisson, negative binomial, zero-inflated Poisson and zero-inflated negative binomial distributions have been considered. First, we propose a multivariate count model in which all counts follow the same distribution and are correlated. Then we extend this model in a sense that correlated counts may follow different distributions. To accommodate correlation among counts, we have considered correlated random effects for each individual in the mean structure, thus inducing dependency among common observations to an individual. The method is applied to real data to investigate variation in food resources use in a species of marsupial in a locality of the Brazilian Cerrado biome. © 2013 Copyright Taylor and Francis Group, LLC.

Yeast diversity isolated from grape musts during spontaneous fermentation from a brazilian winery

Saccharomyces and non-Saccharomyces yeast species from a winery located in Brazil were identified by ribosomal gene-sequencing analysis. A total of 130 yeast strains were isolated from grape surfaces and musts during alcoholic fermentation from Isabel, Bordeaux, and Cabernet Sauvignon varieties. Samples were submitted to PCR-RFLP analysis and genomic sequencing. Thirteen species were identified: Candida quercitrusa, Candida stellata, Cryptococcus flavescens, Cryptococcus laurentii, Hanseniaspora uvarum, Issatchenkia occidentalis, Issatchenkia orientalis, Issatchenkia terricola, Pichia kluyveri, Pichia guilliermondii, Pichia sp., Saccharomyces cerevisiae, and Sporidiobolus pararoseus. A sequential substitution of species during the different stages of fermentation, with a dominance of non-Saccharomyces yeasts at the beginning, and a successive replacement of species by S. cerevisiae strains at the final steps were observed. This is the first report about the yeast distribution present throughout the alcoholic fermentation in a Brazilian winery, providing supportive information for future studies on their contribution to wine quality. © 2013 Springer Science+Business Media New York.

Inteligência coletiva: um olhar sobre a produção de Pierre Lévy

Collective intelligence is an interdisciplinary subject and it has been explored for many different knowledge areas. As a proposal totally tied to the concept of information and information technologies and communication, it is considered as relevant the discussion about the topic within the scope of Information Science. Therefore, a descriptive and exploratory study was carried out from Pierre Levy's work, identifying the precepts of collective intelligence and its ambiences and implications. The research is documental, focusing on determining the state of the art of the production about collective intelligence, verifying what was produced by Pierre Lévy and by other authors about the subject, in order to point out what possible interventions of Information Science on studies about collective intelligence. The research showed that that in the field of Information Science there is little research on the theoretical level about collective intelligence. Nevertheless, discussions about the representation and organization of collective intelligence in digital environments have been recurrent in the present, thus opening new fields of approach between Information Science and conceptual research and practice in collective intelligence.
