First Case of Natural Infection in Pigs: Review of Trypanosoma cruzi Reservoirs in Mexico
Salazar-Schettino Paz María,Bucio Martha Irene,Cabrera Margarita,Bautista Jacobo
Memórias do Instituto Oswaldo Cruz , 1997,
Abstract: An epidemiological research project was performed in the State of Morelos including collection of samples for blood smears and culture, serological tests, and xenodiagnoses from a total of 76 domestic and peridomestic mammals. Two strains of Trypanosoma cruzi were isolated by haemocultures; one from a pig (Sus scrofa), the first case of natural infection reported in Mexico, and the other from a dog (Canis familiaris). This study summarizes current information in Mexico concerning confirmed reservoirs of T. cruzi

Memoria e identidad en la literatura sefardí y mizrahi en Latinoamérica
Sefamí, Jacobo
Sefarad : Revista de Estudios Hebraicos y Sefardíes , 2002,
Abstract: This is the first article that attempts to trace a panoramic view of Sephardi/Mizrahi literature in Latin America. It starts by giving basic information about the migration of these Jewish groups at the end of the 19th and beginning of the 20th century. Later, it identifies more than twenty writers, and establishes two ways to approach Sephardi/- Mizrahi identity: 1) Reflection and study of the splendor of the Golden Age of Medieval Jewish culture in the Iberian Peninsula; and 2) representations of contemporary Sephardim and Mizrahim. Finally, the article proposes Isaac Chocrón's novel, Rómpase en caso de incendio, as the foundational text for contemporary Sephardi/- Mizrahi literature in Latin America. Este es el primer artículo que intenta trazar un panorama de la literatura sefardí/-mizrahi en América Latina. Tras una información básica sobre la migración de esos grupos judíos a finales del siglo XIX y principios del XX, se identifica a más de veinte escritores y se plantean dos modos de acercamiento a la identidad sefardí/mizrahi: 1) la reflexión y estudio del esplendor de la edad dorada de la cultura judía medieval; y 2) vivencias de los sefardíes y mizrahis contemporáneos. Finalmente, se considera la novela Rómpase en caso de incendio, de Isaac Chocrón, como el texto fundacional de la literatura sefardí/mizrahi contemporánea en América Latina.
The family index theorem and bifurcation of solutions of nonlinear elliptic bvp
Jacobo Pejsachowicz
Mathematics , 2011,
Abstract: We obtain some new bifurcation criteria for solutions of general boundary value problems for nonlinear elliptic systems of partial differential equations. The results are of different nature from the ones that can be obtained via the traditional Lyapunov-Schmidt reduction. Our sufficient conditions for bifurcation are derived from the Atiyah-Singer family index theorem and therefore they depend only on the coefficients of derivatives of leading order of the linearized differential operators. They are computed explicitly from the coefficients without the need of solving the linearized equations. Moreover, they are stable under lower order perturbations.
Bifurcation of Fredholm Maps I; The Index Bundle and Bifurcation
Jacobo Pejsachowicz
Mathematics , 2010,
Abstract: We associate to a parametrized family $f$ of nonlinear Fredholm maps possessing a trivial branch of zeroes an {\it index of bifurcation} $\beta(f)$ which provides an algebraic measure for the number of bifurcation points from the trivial branch. The index $\beta(f)$ is derived from the index bundle of the linearization of the family along the trivial branch by means of the generalized $J$-homomorphism. Using the Agranovich reduction and a cohomological form of the Atiyah-Singer family index theorem, due to Fedosov, we compute the bifurcation index of a multiparameter family of nonlinear elliptic boundary value problems from the principal symbol of the linearization along the trivial branch. In this way we obtain criteria for bifurcation of solutions of nonlinear elliptic equations which cannot be achieved using the classical Lyapunov-Schmidt method.
Bifurcation of Fredholm Maps II; The Dimension of the Set of Bifurcation Points
Jacobo Pejsachowicz
Mathematics , 2010,
Abstract: We obtain an estimate for the covering dimension of the set of bifurcation points for solutions of nonlinear elliptic boundary value problems from the principal symbol of the linearization of the problem along the trivial branch of solutions.
Alternativas analíticas en el campo de la movilización social en Colombia: la acción colectiva de alto riesgo. Lecturas a propósito de la protesta campesina en el Tolima
Bautista Bautista,Sandra Carolina;
Estudios Políticos , 2012,
Abstract: this paper presents a theoretical and analytical approach for high-risk collective action, as an explicative tool for different aspects of social mobilization. this perspective allows a better understanding of certain dynamics, in which there seems to be an apparent contradiction between collective action processes and their own adversities. a theoretical contrastation exercise is carried out, based on important authors from the specialized literature, and proposing a conceptual definition for analyzing two experiences of peasant protests in colombia: el líbano and chaparral in the state of tolima. mentioned mobilization processes are described using collected information in the field, press reviews, and multiple documents, leading to the development of analytical categories based on actual information. the specifics of these collective actions are proven; hence, the potential of this approach remains as a powerful tool for future works.

Lecturas a propósito de la protesta campesina en el Tolima High-Risk Collective Action, an Analytical Alternative for Social Mobilization in Colombia: An Approach for Peasant Protests in the State of Tolima, Colombia
Sandra Carolina Bautista Bautista
Estudios Políticos , 2012,
Abstract: Este artículo aborda el debate teórico y analítico de la acción colectiva de alto riesgo, escasamente desarrollado en el contexto colombiano, como herramienta explicativa de diferentes procesos y tipos de movilización social. Esta perspectiva resulta trascendente al darle especificidad a dinámicas en las que existe una aparente contradicción entre procesos de acción colectiva y condiciones adversas a los mismos. Se realiza un ejercicio de contrastación teórica a partir de autores relevantes en la literatura internacional, proponiendo una definición conceptual aplicable para el análisis de dos procesos de movilización campesina ocurridos en los municipios de El Líbano y Chaparral en el Tolima. Se trabaja en la descripción de dichos procesos a partir de información recolectada mediante trabajo de campo, revisión de prensa y diversidad de documentos, haciendo uso de las categorías analíticas derivadas de la definición construida. Se constata la especificidad de este tipo de acciones colectivas y se abre la puerta a la exploración de esta alternativa analítica, a partir de su potencialidad explicativa.

Una estimación de una ecuación gravitacional para los flujos bilaterales de manufacturas Mercosur-Unión Europea
Jacobo, Alejandro D.;
Economia Aplicada , 2010, DOI: 10.1590/S1413-80502010000100005
Abstract: this paper explores the determinants of mercosur-eu bilateral trade flows for 28 manufacturing sectors. in doing so, a gravity equation is estimated for 16 countries for the period 1991-2004. asexpected, the combined output of trade partners, the distance between them, their population and a number of other control variables seem to explain the bilateral trade flows of manufactures.
