1. Antecedents and Consequences of Three Selling Strategies in Social Enterprises
Abstract Purpose This paper analyzed the effect of a long-term strategic orientation and selling capability on three selling strategies, and their effect on the social impact of hybrid social enterprises. Theoretical framework This study relied on the conceptual effect of a long-term orientation and selling capability on selling strategies, as well as the

2. A Novel In Silico Monte Carlo Approach to Optimize a PSD Estimation Problem. Generation of Data Fusion Experiment Rules
ABSTRACT This article analyzes the performance of combining information from Scanning Electron Microscopy (SEM) micrographs with Static Light Scattering (SLS) measurements for retrieving the so-called Particle Size Distribution (PSD) in terms of experimental features. The corresponding data fusion is implemented using a novel Monte Carlo-based method consist

3. Drivers of floristic variation in biogeographic transitions: insights from the ecotone between the largest biogeographic domains of South America
ABSTRACT Ecological transitions usually represent vulnerable ecosystems and high biodiversity. Investigating their drivers is important from both biogeographic and conservationist perspectives. One of these transitions is situated between the two largest biogeographic domains of South America - the Amazon and the Cerrado. We evaluated variation in tree flori

4. Reference sample size for multiple regression in corn
Resumo: O objetivo deste trabalho foi determinar o número de plantas necessário para modelar a produtividade de grãos de milho (Y) em função do comprimento de espiga (X1) e do diâmetro de espiga (X2), por meio do modelo de regressão múltipla Y = β0 + β1X1 + β2X2. Os caracteres Y, X1 e X2 foram mensurados em 361, 373 e 416 plantas, respectivamente,

5. ESTIMATION OF PARAMETERS AND STATES USING A BAYESIAN PARTICLE FILTER FOR THE SULFATE ION ADSORPTION PROCESS IN A FIXED BED COLUMN
Abstract Ensuring that industrial effluents meet quality standards to be released into water bodies is still one of the major environmental concerns. Liquid phase adsoption in fixed bed collumns is one of the most known treatments. Measurements are needed to monitor the process. However, as they are often corrupted by noise from the measuring equipment, perf

6. Sample size for the estimation of Pearson’s linear correlation in crotalaria species
Resumo: O objetivo deste trabalho foi determinar o tamanho de amostra necessário para estimar os coeficientes de correlação linear de Pearson em quatro espécies de crotalária, em níveis de precisão. O experimento foi realizado com Crotalaria juncea, Crotalaria spectabilis, Crotalaria breviflora e Crotalaria ochroleuca, no ano agrícola 2014/2015. Oito

7. Plot size for evaluation of Arabica coffee yield
ABSTRACT. In most cases, in genetic breeding of Arabica coffee, plot size is defined in an empirical manner. It is often based only on the experience of the breeders and the availability of resources, potentially leading to a reduction in precision. Therefore, the aim of this study was to estimate the size of the experimental plot for evaluation of coffee yi

8. Study of repeatability and phenotypical stabilization in kale using frequentist, Bayesian and bootstrap resampling approaches
ABSTRACT. The aim of this study was to obtain information for the genetic improvement of kale through repeatability and phenotypic stabilization studies and to compare methodologies that represent the reliability of the estimated parameters. Thirty-three half-sib progenies were evaluated in a randomized block design with three replicates and six plants per p

10. Metabolisable energy prediction in energy feedstuffs and evaluation of the stepwise validation procedure using bootstrapping
RESUMO A utilização de valores preditos de energia metabolizável aparente (EMA), obtidos a partir de equações de regressão, pode ser útil para instituições de pesquisa e indústrias de nutrição. Contudo, há a necessidade de validação em amostras independentes para assegurar que a equação de predição da EMA seja confiável. Neste estudo, for

11. Optimum plot size of planting and bio-agroeconomic revenues from arugula-carrot intercropping systems in a semi-arid region
Abstract The production of vegetable crops has been characterized as a highly intensive activity in the use of soil, water, inputs and labor in semi-arid regions, being practiced mostly by small family farmers as a way of subsistence, or in the small-scale commercialization of surplus production. Among the agricultural practices that have been successfully u

12. Sample size for estimating mean and coefficient of variation in species of crotalarias
ABSTRACT The objective of this study was to determine the sample size necessary to estimate the mean and coefficient of variation in four species of crotalarias (C. juncea, C. spectabilis, C. breviflora and C. ochroleuca). An experiment was carried out for each species during the season 2014/15. At harvest, 1,000 pods of each species were randomly collected.
