Las Comunidades Virtuales de Aprendizaje(CVA) muestran una visión más amplia la educación y mediante ellas se intenta mejorar las practicas pedagógicas habituales aportar beneficios a organización establecida en los contextos educativos. Una CVA genera través red un espacio donde compartir intereses comunes ella establece conexión humana dispositivos digitales que motivan afectan nuestras emoci...

In this study, five cultivars (Ceres, Zorro, Falcon, Express, and Samourai) of winter rapeseed were classified by using the common vector approach (CVA). For this purpose, seven yield characters (plant height, number of branches per plant, number of pods per plant, number of pods on main stem, number of seeds per pod, pod length and thousand seed weight) of each cultivar were used. The seven an...

Metabolic syndrome is characterized by clustering of metabolic abnormalities which includes insulin resistance, glucose intolerance, central obesity, dyslipidemia and hypertension. This study was carried out to analyse the prevalence of metabolic syndrome and its individual components in 200 patients, 100 each of coronary artery disease (CAD) and cerebrovascular accident (CVA). Subjects attendi...

This paper explores whether witnessing an Intelligent Virtual Agent (IVA) in what appears to be a socially engaging discussion with a Confederate Virtual Agent (CVA) prior to a direct interaction, can prime a person to feel and behave more socially engaged with the IVA in a subsequent interaction. To explore this social priming phenomenon, we conducted an experiment in which participants in a c...

The way monoline insurers estimate the FAS 157 credit value adjustments (CVA) on their ABS CDO insurance portfolios vastly overstates the benefits. We propose a simple method that is more accurate, especially when the counterparty default risk is high. The counterparty default recovery rate is also a critical input. Counterparty credit risk is an important topic today with credit crunch affecti...

A credit valuation adjustment (CVA) is an adjustment applied to the value of a derivative contract or a portfolio of derivatives to account for counterparty credit risk. Measuring CVA requires combining models of market and credit risk to estimate a counterparty’s risk of default together with the market value of exposure to the counterparty at default. Wrong-way risk refers to the possibility ...

[Purpose] The aim of this study was to investigate the effect of lumbar lordosis assistive support (LLAS) on craniovertebral angle (CVA) and mechanical properties of the upper trapezius (UT) muscle in subjects with forward head posture (FHP). [Subjects and Methods] This study recruited 20 subjects with FHP. CVA and muscle tone, viscoelasticity, and stiffness of the UT were measured using Myoton...

Several techniques have been used to quantify the cytotoxicity produced by Mycobacterium tuberculosis bacilli on cell monolayers; however, they are semi-quantitative or time consuming. Herein, a method based on crystal violet (CV) uptake by THP-1 cell monolayers is described. This colorimetric method quantifies the cytotoxic effect as a function of the number of remaining cells after the infect...
