Factor analysis, path analysis, structural equation modeling, and related multivariate statistical methods are based on maximum likelihood or generalized least squares estimation developed for covariance structure models...

New software, OLEX2 , has been developed for the determination, visualization and analysis of molecular crystal structures. The software has a portable mouse-driven workflow-oriented and fully comprehensive graphical use...

Los cambios en la estructura salarial de un país es un área importante de investigación. Sin embargo, la evidencia empírica sobre la evolución de salarios en los países en desarrollo aún es escasa. En este artícu...

We describe a model-based clustering method for using multilocus genotype data to infer population structure and assign individuals to populations. We assume a model in which there are K populations (where K may be unkno...

Increasingly, adult Indigenous language learners are being identified as the “missing generation” of learners who hold great potential to contribute to the revival of Indigenous languages by acting as the middle grou...

The Web has became an obiquitous resource for distributed computing making it relevant to investigate new ways of providing efficient access to services available at dedicated sites. Efficiency is an ever-increasing dema...

MolProbity is a structure-validation web service that provides broad-spectrum solidly based evaluation of model quality at both the global and local levels for both proteins and nucleic acids. It relies heavily on the po...

Abstract For a successful analysis of the relation between amino acid sequence and protein structure, an unambiguous and physically meaningful definition of secondary structure is essential. We have developed a set of si...

SUMMARY: GenAlEx: Genetic Analysis in Excel is a cross-platform package for population genetic analyses that runs within Microsoft Excel. GenAlEx offers analysis of diploid codominant, haploid and binary genetic loci and...

The teaching of qualitative analysis in the social sciences is rarely undertaken in a structured way. This handbook is designed to remedy that and to present students and researchers with a systematic method for interpre...

AIM: This paper is a description of inductive and deductive content analysis. BACKGROUND: Content analysis is a method that may be used with either qualitative or quantitative data and in an inductive or deductive way. Q...

This paper uses an intertemporal general equilibrium asset pricing model to study the term structure of interest rates. In this model, anticipations, risk aversion, investment alternatives, and preferences about the timi...

BACKGROUND: The Avogadro project has developed an advanced molecule editor and visualizer designed for cross-platform use in computational chemistry, molecular modeling, bioinformatics, materials science, and related are...

The Guañacos fold and thrust belt, located between 37° and 38° S in the eastern foothills of the Main Andes is characterized at its eastern border by a series of NE, NW and N- neotectonic faults associated with the An...

El tamaño y la estructura de la población canina de San Martín de los Andes se describió utilizando información proveniente de encuestas obtenidas a través de un muestreo estratificado (9 estratos y 624 lotes) y de...

Comparative protein modeling is increasingly gaining interest since it is of great assistance during the rational design of mutagenesis experiments. The availability of this method, and the resulting models, has however ...

Se estudió la estructura espacial de poblaciones de herbívoros silvestres -guanacos, choiques y maras- en Península Valdés (PV), Provincia de Chubut. Se utilizaron modelos que dan cuenta de la variación en la abunda...

Modern requirement engineering approaches divide the elicitation process in two different stages: one focused on analyzing the context where the system-to-be will be used and another centered on designing software soluti...

Continuing his groundbreaking analysis of economic structures, Douglass North develops an analytical framework for explaining the ways in which institutions and institutional change affect the performance of economies, b...

En el presente trabajo se analizan mediciones de dos y tres componentes instantáneas de la velocidad del viento, adquiridos simultáneamente a dos y cuatro alturas, en el seno del bosque y por arriba del mismo, en una t...
