Capacidades de internet banking e desempenho das pequenas empresas: o valor de negócio da TI na perspectiva de capacidades externas

The purpose of this research is to identify the extent to which Internet Banking Capabilities are related to the performance of small business (bank customers) at the processes and firm levels. As a research method, a survey with small businesses which use internet banking has been conducted. For data analysis, we used Structural Equation Modeling estimated with Partial Least Squares (PLS). The results indicate the direct impact of Internet Banking Capabilities on process performance, which sequentially impacts the performance at the firm level. On the other hand, there is no direct impact of Internet Banking Capabilities on firm performance. Limitations and research opportunities are included in the conclusions.Keywords: IT value, Internet Banking Capabilities, process performance, firm performance.Esta pesquisa objetiva identificar em que medida as capacidades de internet banking estão associadas ao desempenho de pequenas empresas (clientes bancários) nos níveis de processos e de firma.

Abundância de gavião-real e gavião-real falso numa área sob impacto de reservatório no Baixo e Médio rio Xingu

In the Brazilian Amazon, two monospecific genera, the Harpy Eagle and Crested Eagle have low densities and are classified by IUCN as Near Threatened due to habitat loss, deforestation, habitat degradation and hunting. In this study, we evaluate occurrence of these large raptors using the environmental surveys database from Belo Monte Hydroelectric Power Plant. Integrating the dataset from two methods, we plotted a distribution map along the Xingu River, including records over a 276-km stretch of river. Terrestrial surveys (RAPELD method) were more efficient for detecting large raptors than standardized aquatic surveys, although the latter were complementary in areas without modules. About 53% of the records were obtained during activities of wildlife rescue/flushing, vegetation suppression or in transit. Between 2012 and 2014, four Harpy Eagles were removed from the wild; two shooting victims, one injured by collision with power lines and one hit by a vehicle. Also, seven nests were mapped. The mean distance between Harpy Eagle records was 15 km along the river channel, with a mean of 20 km between nests near the channel, which allowed us to estimate 20 possible pairs using the alluvial forest, riverine forest and forest fragments. Territories of another ten pairs will probably be affected by inundation of the Volta Grande channel, which is far from the main river. The average distance between Crested Eagle records was 16 km along the river channel. The only nest found was 1.3 km away from a Harpy Eagle nest. The remnant forests are under threat of being replaced by cattle pastures, so we recommend that permanently protected riparian vegetation borders (APP) be guaranteed, and that forest fragments within 5 km of the river be conserved to maintain eagle populations. © 2015, Instituto Internacional de Ecologia.

Impacto das Capacidades de Internet Banking no Desempenho: Um estudo na perspectiva de clientes utilizando Partial Least Squares (PLS)

Esta pesquisa objetiva identificar em que medida as Capacidades de Internet Banking impactam o Desempenho do cliente/usuário nos níveis de Processos e de Firma. Como método de pesquisa, realizou-se uma Survey com empresas de pequeno porte que utilizam o Internet Banking. Para análise de dados, utilizou-se Partial Least Squares (PLS). Os resultados apontam para o impacto direto das Capacidades de Internet Banking sobre o Desempenho no nível de Processos, que por sua vez impacta o Desempenho em nível de Firma. Por outro lado, inexiste relação de impacto direto das Capacidades de Internet Banking sobre o Desempenho no nível de Firma. Limitações e oportunidades de pesquisa constam nas conclusões

Predictive equations for resting metabolic rate are not appropriate to use in Brazilian male adolescent football athletes.

High accuracy in estimating energy expenditure is essential for enhancing sports performance. The resting metabolic rate (RMR), as a primary component of total energy expenditure (TEE), is commonly estimated using predictive equations. However, these references may not be applicable to adolescent athletes. The purpose of this cross-sectional study was to analyse the differences between predicted RMR in relation to energy expenditure measured by indirect calorimetry (IC) among 45 Brazilian male adolescent football athletes. Indirect calorimetry (IC) and anthropometric (bioimpedance) measurements were recorded at a single visit to the laboratory after fasting overnight. The mean age was 15.6 ± 1.14 years, body mass was 63.05 ± 7.8 kg, and height was 172 ± 7.5 cm. The RMR values predicted by equations proposed by the Food and Agriculture Organization (FAO) (United Nations), Henry and Rees (HR), Harris Benedict (HB), and Cunningham (CUN) were compared with IC RMR values, by correlation analysis. The FAO and HR predictive equations yielded different values from IC (IC: 1716.26 ± 202.58, HR: 1864.87 ± 147.78, FAO: 1854.28 ± 130.19, p = 0.001). A moderate correlation of 0.504 was found between the results of HB and IC. In the survival-agreement model, the CUN equation showed low disagreement with the IC RMR, with error values between 200 and 300 kcal/day. The results showed that HB and CUN yielded similar values as IC, with the CUN equation showing low disagreement with IC; hence, adolescent athletes should undergo evaluation with precise laboratory methods to ensure that accurate information about RMR is recorded
