Analysis of psychological aspects of Lovemarks formation

El presente trabajo es una revisión de literatura que busca contribuir al entendimiento de los procesos psicológicos subyacentes en la Teoría de Roberts sobre Lovemarks que, dentro del campo del marketing, ha buscado reemplazar la idea que se tiene sobre las marcas. La primera parte proporciona una introducción de lo que ha sido la evolución de las marcas desde una perspectiva psicológica y de mercadeo. En la segunda parte se explica la teoría de Lovemarks haciendo énfasis en sus componentes: el eje amor/respeto, las características de misterio, sensualidad e intimidad. Adicionalmente, se soporta esta teoría a través de literatura complementaria y casos de aplicación exitosos. La tercera parte, corresponde a la identificación y análisis de los procesos y aspectos psicológicos que explican la formación de un Lovemark: percepción, memoria, motivación individual y social y emoción. La cuarta y última parte contiene las conclusiones e implicaciones en la formación de la relación entre el consumidor y una marca.

3D Analysis of the TCR/pMHCII Complex Formation in Monkeys Vaccinated with the First Peptide Inducing Sterilizing Immunity against Human Malaria

T-cell receptor gene rearrangements were studied in Aotus monkeys developing high antibody titers and sterilizing immunity against the Plasmodium falciparum malaria parasite upon vaccination with the modified synthetic peptide 24112, which was identified in the Merozoite Surface Protein 2 (MSP-2) and is known to bind to HLA-DR beta 1*0403 molecules with high capacity. Spectratyping analysis showed a preferential usage of V beta 12 and V beta 6 TCR gene families in 67% of HLA-DR beta 1*0403-like genotyped monkeys. Docking of peptide 24112 into the HLA-DR beta 1*0401-HA peptide-HA1.7TCR complex containing the VDJ rearrangements identified in fully protected monkeys showed a different structural signature compared to nonprotected monkeys. These striking results show the exquisite specificity of the TCR/pMHCII complex formation needed for inducing sterilizing immunity and provide important hints for a logical and rational methodology to develop multiepitopic, minimal subunit-based synthetic vaccines against infectious diseases, among them malaria.

The High Education Teacher, an Agent of Moral Development

The article shows the classroom like an workplace to move moral development, from the relationship between students and professors in the university atmosphere. It proposes elements to take to the practice the ethics education a transverse curriculum line. It assumes the ethics, from a plural perspective, founded on the knowledge and the human action. It joins the integral formation with the conceptions of education, curriculum, pedagogical models and methodologies of education. It proposes actions to demonstrate the commitment of the professor with the integral formation. Finally, concludes that the professor is agent of moral development and that in the classroom is constructed: identity, autonomy and responsibility, from open and plural relation between professors and students and between these and the knowledge.

Renovación curricular en programas de ciencias de la salud y su impacto en las prácticas pedagógicas de los profesores

Este artículo es un avance del proyecto de investigación “Transformaciones de las prácticas pedagógicas de los profesores en un proceso de renovación curricular”. Su marco conceptual se fundamenta en el análisis de cuatro ejes centrales: el primero hace referencia al concepto de currículo, que compromete varios aspectos relacionados con los diferentes actores del sistema educativo; el segundo afronta las renovaciones curriculares en programas de Ciencias de la Salud, que permite aclarar y determinar lo que la comunidad académica entiende al respecto, sus características, fines y efectos; el tercero analiza la información para identificar los factores que posibilitan la apropiación o no de los principios de las renovaciones curriculares reflejados en las prácticas pedagógicas de los profesores; el cuarto explora conceptualizaciones acerca de cómo el profesor interpreta y orienta su actuar educativo. Finalmente, se propone una discusión cuyo hilo conductor responde a las siguientes preguntas: ¿Cómo los procesos de renovación curricular en programas de formación profesional en Ciencias de la Salud impactan las prácticas pedagógicas de los profesores? ¿Cuáles son los factores que posibilitan la apropiación de los principios de las renovaciones curriculares en las prácticas pedagógicas de los profesores en programas de formación profesional en Ciencias de la Salud?

Health care network formation and policyholders' welfare

We develop a model in which two insurers and two health care providers compete for a fixed mass of policyholders. Insurers compete in premium and offer coverage against financial consequences of health risk. They have the possibility to sign agreements with providers to establish a health care network. Providers, partially altruistic, are horizontally differentiated with respect to their physical address. They choose the health care quality and compete in price. First, we show that policyholders are better off under a competition between conventional insurance rather than under a competition between integrated insurers (Managed Care Organizations). Second, we reveal that the competition between a conventional insurer and a Managed Care Organization (MCO) leads to a similar equilibrium than the competition between two MCOs characterized by a different objective i.e. private versus mutual. Third, we point out that the ex ante providers’ horizontal differentiation leads to an exclusionary equilibrium in which both insurers select one distinct provider. This result is in sharp contrast with frameworks that introduce the concept of option value to model the (ex post) horizontal differentiation between providers.

Heterogeneity and the formation of risk - sharing coalitions

We offer a new explanation of partial risk sharing based on coalition formation and segmentation of society in a risky environment, without assuming limited commitment and imperfect information. Heterogenous individuals in a society freely choose with whom they will share risk. A partition belonging to the core of the membership game obtains. Perfect risk sharing does not necessarily arise. Focusing on mutual insurance rule and assuming that individuals only differ with respect to risk, we show that the core partition is homophily-based. The distribution of risk affects the number and size of these coalitions. Individuals may pay a lower risk premium in riskier societies. A higher heterogeneity in risk leads to a lower degree of risk sharing. We discuss how the endogenous partition of society into risk-sharing coalitions may shed light on empirical evidence on partial risk sharing. The case of heterogenous risk aversion leads to similar results.

Natural resources, redistribution and Human capital formation

How do resource booms affect human capital accumulation? We exploit time and spatial variation generated by the commodity boom across local governments in Peru to measure the effect of natural resources on human capital formation. We explore the effect of both mining production and tax revenues on test scores, finding a substantial and statistically significant effect for the latter. Transfers to local governments from mining tax revenues are linked to an increase in math test scores of around 0.23 standard deviations. We find that the hiring of permanent teachers as well as the increases in parental employment and improvements in health outcomes of adults and children are plausible mechanisms for such large effect on learning. These findings suggest that redistributive policies could facilitate the accumulation of human capital in resource abundant developing countries as a way to avoid the natural resources curse.
