Science has become progressively more complex, requiring greater integration and collaboration between individuals, institutions and areas. Networking research establishes common rules and offers a suitable framework for this cooperation. Therefore, it is a good choice for both scientists and policy-makers. The objective of this study is to know whether the scientists perform better within thes...

BACKGROUND Falling is a common but devastating and costly problem of aging. There is no consensus in the literature on whether the spatial and temporal gait parameters could identify elderly people at risk of recurrent falls. OBJECTIVE To determine whether spatiotemporal gait parameters could predict recurrent falls in elderly women. METHOD One hundred and forty-eight elderly women (65-85 y...

black stem is one of the most important fungal diseases of sunflower which is caused by phoma macdonaldii. this research was conducted to clarify the interactions between a few breeder lines and wild-type accessions of sunflower with seven isolates of phoma macdonaldii, the causal agent, under controlled conditions. the experiment was carried out in randomized complete block design with three r...

Five-year data of SO2, PM10, NO, NO2, O3 and CO levels recorded at two air pollution monitoring stations in the city of Salamanca were analysed using a HJ-Biplot Simultaneous Representation analysis method in order to determine the possible relationships among the different pollutants and to gain insight into the temporal evolution of pollution in this city. Use of this statistical method prove...

Background Gait is an extremely complex motor task; therefore, gait data should encompass as many gait parameters as possible. Objective To provide reference values for gait measurements obtained from a Brazilian group of community-dwelling elderly females between the ages of 65 and 89 years and to apply the PCA-biplot to yield insight into different walking strategies that might occur during t...

Se presentan algunos aspectos teóricos sobre la relación entre las técnicas clásicas de MANOVA y Biplot, que son base gráfica MANOVA-Biplot. aplica esta técnica a un conjunto datos referentes al uso del suelo en tres regiones definidas por el Ecuador. indagan sus diferencias con propósito lograr una caracterización sintética sirva para compararlas estadísticamente sea utilidad proceso toma deci...

The HJ biplot is a multivariate analysis technique that allows us to represent both individuals and variables in space of reduced dimensions. To adapt this approach massive datasets, it necessary implement new techniques are capable reducing the dimensionality data improving interpretation. Because this, we propose modern obtaining called elastic net biplot, which applies penalty improve interp...

In this paper Non-Symmetric Correspondence Analysis (NSCA, Lauro & D'Ambra, 1984; D'Ambra & Lauro, 1989, 1992) is proposed as an useful technique for evaluating contingency table with a dependence structure, in particular within the context of comparing market share di erences. Technical aspects of the method are discussed with a view towards application, giving special attention to the biplot ...
