La reputación como ventaja competitiva sostenible
2019
En los actuales contextos globalizados, las empresas se encuentran en una búsqueda incesante por diferenciarse. La oferta de bienes y servicios en general ha crecido, tanto en cantidad como en calidad. A tal grado se produce este fenómeno que, si la empresa no encuentra una buena razón (y la comunica correctamente) para ser elegida por los consumidores, se condena a perder mercado y/o rentabilidad. Las tradicionales fuentes de ventaja competitiva se encuentran sobreexplotadas. Además de presentar problemas con su sostenibilidad. En principio, es necesario definir la reputación corporativa y diferenciarla de otros conceptos con los cuales se relaciona. Con esta base, se procederá a referirse…

Biopiracy in India: Seed diversity and the scramble for knowledge.
2018
Abstract Background: Biopiracy has usually been discussed mostly in the context of the life sciences, sometimes in dialogue with legal debates or political implications. This paper provides a humanities perspective on contemporary discussions of biopiracy and biopatenting. Hypothesis It proceeds from the hypothesis that contemporary debates and practices of biopiracy can be understood as harking back to colonial legacies, which systematically disregard “native” knowledge or seek to appropriate it for their own purposes. Results Drawing on the work of Vandana Shiva, the present article seeks to redefine the notion of ownership of knowledge from a cultural studies perspective. Exploring the 2…

The leisure construction in adolescents and this influence for development of criminal careers
2013
La construcción de actividades de ocio incide directamente en el desarrollo evolutivo de los adolescentes, capacitándolos para una sana socialización en sus espacios cotidianos. La complejidad que plantea el diseño de actividades y programas de ocio requiere el esfuerzo común de los diferentes agentes; así, tanto las administraciones públicas, como los padres, profesionales, los propios adolescentes y las entidades gestoras de estos programas han de coordinar sus esfuerzos en pro de desarrollar equilibradamente los espacios con las propuestas para el ocio. De estas actividades, las encaminadas hacia el recreo supervisado permiten crecer en positivo, pero la alarma aparece cuando los espacio…
Data from: Large birds travel farther in homogeneous environments
2019
Aim: Animal movement is an important determinant of individual survival, population dynamics, and ecosystem structure and function. Yet it is still unclear how local movements are related to resource availability and the spatial arrangement of resources. Using resident bird species and migratory bird species outside of the migratory period, we examined how the distribution of resources affect the movement patterns of both large terrestrial birds (e.g., raptors, bustards, hornbills) and waterbirds (e.g., cranes, storks, ducks, geese, flamingos). Location: Global Time Period: 2003 - 2015 Major taxa studied: Birds Methods: We compiled GPS tracking data for 386 individuals across 36 bird specie…
Analysis of complement C3 activation products in human atherosclerotic lesions.
1991
Abstract Cleavage of the complement C3 protein is essential for complement activation. Saline extracts of human atherosclerotic lesions were examined by various techniques for the presence of C3 cleavage fragments. Crossed intermediate gel immunoelectrophoresis revealed that native C3 was the predominate C3 protein in extracts and that the C3dg fragment was also detected. SDS-PAGE/ Western blot analyses of lesion extracts employing monoclonal antibodies directed at C3c and C3dg fragment determinants demonstrated molecular weight bands corresponding to the known molecular weights of all the physiologic C3 cleavage fragments, except Cab which is known to have a short half-life. After C3, the …
Investigations on the Steroidal Anti-Inflammatory Activity of Triterpenoids fromDiospyros leucomelas*
1995
Three triterpenes were isolated from Diospyros leucomelas and identified as betulin, betulinic acid, and ursolic acid. They showed anti-inflammatory activity in the carrageenan and serotonin paw edema tests and TPA and EPP ear edema tests. The blockade of their effects by progesterone, actinomycin D, and cycloheximide has served to determine the mechanism of action in relationship with that of glucocorticoids. Betulinic acid was the most affected and therefore a mode of action similar to these drugs may be postulated for it.
Clinical pharmacology of citrus aurantium and citrus sinensis for the treatment of anxiety
2018
Objective. The aim of this review is to analyze preclinical and clinical studies investigating the anxiety effects ofCitrus aurantiumorCitrus sinensisessential oils (EOs).Design. The bibliographic research was made on the major scientific databases. Analysis included only articles written in English and published on peer-reviewed scientific journals describing preclinical experiments and clinical trials carried out to investigate the antianxiety effects ofCitrus aurantium or Citrus sinensisEOs on anxiety disorders. Clinical studies reporting the antianxiety effects of products containingCitrus aurantiumorCitrus sinensisEOs in combination with other active substances, including medicinal pla…
Monoclonal antibodies against components of the classical pathway of complement.
1989
Activation of the classical pathway of complement involves several binding and enzymatic cleavage processes. Binding and enzymatic activation results in the appearance of new structures in the individual components. This report describes the different activation steps for C1q, C1r, C1s, C4 and C2 and summarizes monoclonal antibodies reported so far which recognize either conserved epitopes or activation-dependent epitopes with particular emphasis on neoepitopes occurring during the activation cascade.
