Caracterización genética de poblaciones humanas de tres regiones del Perú, para su identificación mediante el uso de 30 marcadores de inserción y deleción

Zuñiga Ccoicca, Luis Armando January 2018 (has links)
Se caracterizó genéticamente 136 peruanos mestizos de las regiones norte, centro y sur del Perú, empleando un conjunto de 30 marcadores autosómicos no codificantes de inserción y deleción denominados INDELs. Se evaluó la diversidad genética como una medida de la heterosigosidad media en la población y se obtuvieron las frecuencias alélicas y genotípicas para los 30 marcadores estudiados. De los análisis de varianza molecular (AMOVA) y distancias genéticas entre poblaciones (Fst) no se observó diferencias significativas entre los grupos norte, centro y sur del Perú, pero si una alta diversidad genética a nivel de individuos (97.86%), es decir que la población mestiza del Perú se presenta en estos análisis como una unidad poblacional sin subestructura genética. Ninguno de los 30 marcadores INDELs mostraron desviaciones al Equilibrio de Hardy–Weinberg. Por otro lado los análisis de estructura poblacional en el Perú no muestran algún grado de agrupamiento que evidencie subestructura, sin embargo a una escala intercontinental se realizó una comparación con datos que emplearon el mismo sistema de marcadores en la población de España, País Vasco y Uruguay resultando un valor de K igual a 02 (dos), donde se observa que el Perú se muestra como un grupo poblacional con muy poco componente genético español a diferencia de Uruguay donde el componente español es predominante. De estos resultados se infiere que la población peruana posee mayormente un componente genético americano nativo que podría ser andino o amazónico. Adicionalmente se evaluó los parámetros estadísticos de interés forense. Este sistema de 30 marcadores muestra un alto Poder de Discriminación ( 99.99999999%) y una baja probabilidad de coincidencia (0.00000000001426561820), estas variables son importantes en genética forense ya que posee una alta capacidad de discriminar un perfil genético de ADN de otro que se haya encontrado en la misma escena del crimen, adicionalmente al poseer una baja probabilidad de coincidencia significa que la probabilidad de que dos individuos no relacionados tengan el mismo perfil genético en la escena del crimen es prácticamente cero. / Tesis

El indígena y el mestizo en la comunidad de Marcará incluyendo un apéndice sobre antropología aplicada en Marcará

Ghersi Barrera, Humberto January 1960 (has links)
El documento digital no refiere asesor / El año de publicación de la tesis ha sido obtenido del catálogo electrónico de la Biblioteca Central Pedro Zulen de la Universidad Nacional Mayor de San Marcos / La investigación en Marcará busca definir la personalidad social del grupo estudiando sus manifestaciones culturales peculiares; los cambios ocurridos debido al acrecentamiento y acentuación de los contactos culturales con núcleos cercanos y aún con los lejanos; los cambios producidos por la introducción de elementos tecnológicos correspondientes a la cultura occidental y por consiguiente los problemas derivados de ellos y, los conflictos suscitados por el impacto de la tecnología moderna en la región. Otro de los objetivos fue el de observar en esta comunidad tipo, la a reacciones personales e intergrupales.y la situación de tensión existente con las comunidades vecinas. Para hacer un estudio comparativo del fenómeno cultural en la región era necesario disponer correlativamente los resultados de las investigaciones antropológicas en áreas fines como Vicos, Pati, Recuayhuanca, Shumay, etc. que participen de un sistema de vida más o menos semejante, que tengan los mismos problemas, puesto que interpretando estos últimos, las conclusiones resultantes harían posible una solución adecuada. / Tesis

Mestizo Visionary Art of the Americas in the Late Twentieth Century: Hallucinogens, Politics, Aesthetics and Mass Consumer Culture in the United States, Mexico, and Colombia

Cadena Botero, Juan David January 2022 (has links)
Unlike their European predecessors in the experimentation with hallucinogens and aesthetics who undertook it as an exotic tradition brought from afar, many Latin American and North American authors turned to visionary practices and substances (cannabis, peyote, psilocybin mushrooms and ayahuasca, among others) as a main element of their own cultural heritage and territory. Though commonly restricted to the specific category of "psychedelia," the narratives in this corpus from the 20th century only acquire their true depth once included within a much vaster realm, that of visionary traditions, mostly originated in non-Western sources --with exceptions among divinators, witches and sorcerers in Europe -- both in the Old World of the Orient and Africa, but particularly in the New World, in America. Problematically blurring use and exchange value, the 20th century seized these substances as sources of forbidden pleasures which alienated laborers, while their prohibition generated immense fortunes that destabilized democracies throughout the continent, motivated violence, and funded mafias, guerrillas and paramilitary groups. Yet, visionary plants and practices spread with a transcultural power that even today allows for the survival of ethnic groups and traditional knowledge long hidden, while also feeding urban consumptions that generate innumerable subcultures, time and again misunderstood as a sign of decadence. In this dissertation these "underworld" practices are also manifestations of something prior and parallel to the birth of a culture of mass consumers: they mark an encounter between Indigenous, Afro, rural and mestizo influences in the voices of authors who contributed to culture from the margins of very hierarchical and racist societies, and assumed a leading role in their intellectual debate, capturing its mixtures, dark humor, conflicts and transculturations via writing and films. Initially marginalized in the low worlds of taverns, destitute neighborhoods, crime, prisons and prostitution venues, hallucination and hallucinogens--simultaneously a colonial anathema and a sacred pre-Columbian ritual of transcendence--survive and thrive, passing on to the urban minorities of artists and thinkers I will examine in this dissertation, now even including synthetics like Lysergic Acid Diethylamide (LSD). Late Avant-gardes between the 1950s and 1990s--beatniks, counterculture, yippies and Chicanos in the US, the Onda generation and the "jipitecas'' in Mexico, and the "nadaístas'' and the Cali group in Colombia--partially rescued this knowledge, but, above all, its consumptions, preserving some of them as an original heritage within their metaphysics, politics and aesthetics, and as a core part of many of their ideological and secular inquiries. Banned and misconstrued by the viceregal, republican, national and transnational elites, both in the colonial past, and in the contemporary moment of an hemispheric circuit -- within the geopolitics of Nixon‘s War on Drugs -- visionary and hallucinogenic uses continue shaping much of the cultural panorama of America today. The variety of films and texts observed in this project gives a measure of the true heterogeneity of Latin American and US authors of the 20th century: In their works we reconnect a fracture that divides not only two, but many worlds, while it makes possible, for once, to conceive the simultaneous reality of them all.
