Abstract:

The American Kennel Club and the Fédération Cynologique Internationale recognize two phenotypic variants of Great Dane breed denominated American and European varieties. Historically, these varieties have been segregated according to morphological characteristics. In an attempt to obtain a better characterization, breeders have been interested in the genetic parameters that could evaluate the within-breed diversity. In this document, we studied the genetic structure of Great Dane breed with 10 STR markers in 88 dogs using capillary electrophoresis. Cluster analysis, population differentiation and phylogenetic analyses revealed that American and European varieties are genetically independent. Nevertheless, within the American variety a genetic stratification was found. Additionally, a high misclassification (28%) was detected, which could be due to wrong registration or false paternity. Our results support the importance to deem genetic markers as useful tools in breeding control. Similarly, these studies serve as an accurate reference to establish standards by dog breeding associations and for choosing among dogs for inter-breeding. Nevertheless, genetic tools are only a complement of morphological methods, since both are reshuffling the control over the breeding line. Notwithstanding, this database provides an overall and scape concerning the impact of genetic diversity within-breed. Unmistakably, more databases are needed to increase the quality of the breeding line as well as the number of STR in order to study, with more detail, the genetic structure in the Great Dane race.

Abstract: Pelliciera rhizopharae Triana & Planchon es reported for the first time in the Atlantic Coast. This species has been considered so far as an endemics in the tropical American Pacific coast. Some biogeographical and taxonomic observations are included, as well as a description of the material found. Se reporta por primera vez el "mangle pi uelo" Pelliciera rhizophorae Triana & Planchon para la costa del Atlántico. Esta especie es considerada hasta la fecha endémica en la costa tropical del Pacifico americana. Acompa an el reporte algunas observaciones de carácter biogeográfico y taxonómico, así como una descripción de los ejemplares encontrados.

Pensamiento & Gestión , 2012,
Abstract: we present a detailed analysis of the various stages of a performance evaluation process and the main human resource trends and those generic trends that are related to the performance evaluation, which directly affect the conduct of an audit. the methodology is based mainly on literature and article reviews which were published in specialized publications. the results of this research are presented with a broad definition of performance evaluation, referencing mainly contemporary authors, and we continue with a theoretical and a graphic presentation of the evaluation process. subsequently, the major trends affecting human resource management are described, as well as performance evaluation, making a comparison between past and future visions of a series of concepts related to the evaluation, and concluding with contemporary references to concepts related with audits of performance evaluation.

Abstract: Se presenta un análisis detallado de las diversas etapas del proceso de evaluación de desempe o y las principales tendencias genéricas de recursos humanos y aquellas tendencias que se relacionan directamente con la evaluación, que inciden directamente al efectuar una auditoría. La metodología utilizada se basó principalmente en revisiones bibliográficas y de artículos en publicaciones especializadas. Los resultados de esta investigación se presentan con una definición amplia del concepto de evaluación, referenciando diversos autores, principalmente contemporáneos, y continúa con una presentación teórica y gráfica del proceso de evaluación; posteriormente se muestran las principales tendencias que afectan a la administración de recursos humanos, como también a la evaluación de desempe o, realizando comparaciones entre la visión pasada y futura de una serie de conceptos vinculados con la evaluación, y se concluye con referencias contemporáneas de conceptos relacionados con la auditoría a la evaluación del desempe o.

Abstract: the present work was designed in order to obtain the cut off point, to be used in a shelf life study on whole stirred strawberry yogurt. the study was simultaneously carried out in argentina, chile and costa rica, assaying the same kind of product, elaborated in each one of the countries. the sensory quality parameters obtained from trained panelists and the consumers acceptability, were correlated by using the cut off point methodology through a quality evaluation by the karlsruhe scale. according to preliminary studies, the storage at 42oc produced considerable damage on parameters such as ph, acidity (volumetric assay), viscosity and sensory quality. for each sample, the cut off point was determined. this value corresponds to the threshold score for the sensory quality, where the consumer starts to perceive negative changes in the product, when comparing with the fresh product. the rejection percentage was also calculated according to the cut off point. the cut off points and the percentage of rejection obtained by the three participating countries were similar. data obtained from costa rica showed changes in color, acidity and rancidity. argentinean yogurts developed acidity that had a negative effect on texture, appearance and residual flavors. chilean samples presented a sensory quality that remains almost without change through the studied time. the differences of the deterioration pattern amongst the three countries, demonstrates that the products are different in formulation and elaboration process, in spite of been the same kind of yogurt. this could be explained by differences specified in the regulation of each country. for instance the trading conditions are not similar; the local industry should satisfy the needs of their consumers and consider the variables that leads to the acceptability of the product by the objective market.

Abstract: justification: there is a group of patients with chronic refractory chest angina, who are not ideal candidates for surgical or percutaneous revascularization and who although having a good medical handling continue to experience severe episodes of angina. the spinal electrical stimulator is a neuromodulator used as an alternative to treat these patients. objectives: to realize a review of scientific literature regarding the spinal electric stimulation in the treatment of chest angina, its mechanism of action, benefits and its cost effectiveness. materials and methods: using the cochrane methodology, a search of articles published from january 1980 to january 2007 in medline using the terms ?spinal cord stimulation?, was realized. the papers considered most pertinent were selected. conclusions: the anti-ischemic effect of the electrical spinal stimulator reduces the episodes of chest angina, improves the quality of life and the tolerance to exercise, diminishes the hospital stay and delays the appearance of ischemic signs.
