Presencia portuguesa en México colonial
No full textThe article presents a panoramic view of portuguese presence in New Spain, whose early members were participants in the conquest of the land, amongst which was Juan Rodríguez Cabrillo. Without being exhaustive, the author gives information about different groups of portugueses that along three centuries of colonialism take residence in the regions of New Spain. Not few of them were jews that came with the hope of living in peace according with the religion of their elders, situation that made them prisoners of the Inquisition tribunal. Deserve special attention those who participated in the so called "Great Conspiracy", apparent symphatizers of the rebellion that the duke of Braganza organized in Portugal against Philip the IVth of Spain. To such "Great Conspiracy" was linked the irish Guillén de Lampart. It is also mentioned the portuguese presence in the colonizing enterprise in California. Finally, there are multiple references to the varied origin of the novohispanic portugueses, whom came from many different cities of the old country.El artículo ofrece un panorama de la presencia portuguesa en Nueva España, cuyos primeros exponentes participaron ya en la conquista de estas tierras, entre los cuales se contó Juan Rodríguez Cabrillo. Sin ser exhaustivo, el autor da información sobre diversos grupos de portugueses que a lo largo de los tres siglos de la colonia se avecindaron en estas regiones. De entre ellos, no pocos eran judíos que venían con la esperanza de vivir en paz según la religión de sus mayores, por lo que se hicieron reos del tribunal inquisitorial. Merecen especial atención aquellos que participaron en la llamada "Conspiración grande", aparentemente simpatizantes de la rebelión que el duque de Braganza había organizado en Portugal contra Felipe IV. A dicha "Conspiración grande" se vinculó el irlandés Guillén de Lampart. Asimismo se aborda la presencia portuguesa en la empresa colonizadora de la California. Finalmente, a lo largo del trabajo se hace referencia en múltiples ocasiones al origen tan variado de los portugueses novohispanos, quienes venían de muy distintas ciudades de aquel país

Search for Top Squark Pair Production in Compressed-Mass Scenarios in Proton-Proton Collisions at S=8 Tev Using the Αt Variable
No full textAn inclusive search is performed for supersymmetry in final states containing jets and an apparent imbalance in transverse momentum, p→T miss, due to the production of unobserved weakly interacting particles in pp collisions at a centre-of-mass energy of 8 TeV. The data, recorded with the CMS detector at the CERN LHC, correspond to an integrated luminosity of 18.5 fb−1. The dimensionless kinematic variable αT is used to discriminate between events with genuine p→T miss associated with unobserved particles and spurious values of p→T miss arising from jet energy mismeasurements. No excess of event yields above the expected standard model backgrounds is observed. The results are interpreted in terms of constraints on the parameter space of several simplified models of supersymmetry that assume the pair production of top squarks. The search provides sensitivity to a broad range of top squark (t˜) decay modes, including the two-body decay t˜→cχ˜1°, where c is a charm quark and χ˜1° is the lightest neutralino, as well as the four-body decay t˜→bff¯′χ˜1°, where b is a bottom quark and f and f¯′ are fermions produced in the decay of an intermediate off-shell W boson. These modes dominate in scenarios in which the top squark and lightest neutralino are nearly degenerate in mass. For these modes, top squarks with masses as large as 260 and 225 GeV are excluded, respectively, for the two- and four-body decays. © 2017 The Autho
La recepción de la obra de Jean-Baptiste Say en España: la teoría económica del empresario
No full textEste trabajo analiza la difusión de la teoría del empresario de Jean-Baptiste Say
en España, como último eslabón de una línea de pensamiento que tiene su origen
en Richard Cantillon. Se prueba que la particularidad de este autor es su gran difusión
en el siglo XIX español –siendo uno de los más traducidos– y la escasa
influencia de su teoría económica del empresario. Explicamos las razones de una
paradoja que deja sin fundamentos teóricos a cualquier política económica destinada
al desarrollo del tejido empresarial nacional. Son presentados los mecanismos
de difusión, tanto directos, por medio de traducciones, como indirectos, por
medio de autores españoles que pudieron difundir esta teoría de la función empresarial.
Nos interesa conocer la recepción por parte de los autores españoles de
la teoría del empresario de Say, determinar su grado de comprensión, de interpretación
en relación con la realidad nacional, de revisión teórica, e incluso conocer
si la fuente real de la idea a transmitir es el propio autor o alguna otra.This paper illustrates the spread of Jean-Baptiste Say’s entrepreneur theory in Spain –a last contribution within the French tradition in which Richard Cantillon and A. R. J. Turgot were predecessors. We attempt to demonstrate that this is a special case, because, even though J. B. Say was the most important author from a publishing point of view, his economic theory of entrepreneurship had very little influence. The spread of economic ideas by way of translation and Spanish authors which employed J. B. Say’s economic theory, give possible explanations to a
paradox which had left economic policy without a theoretical reference. We analyse how Say’s entrepreneur theory was received among Spanish authors in the 19th century, its degree of comprehension and the analytical additions made, and attempt to identify the real source of transmission

Roberta Jaffe, Founding Director, Life Lab Science Program, Co-Founder of Community Agroecology Network
No full textRoberta (Robbie) Jaffe grew up in New York in the 1950s, and moved to Florida when she was sixteen. She attended the University of Florida and University of South Florida, and graduated with a degree in sociology. During and after college she was deeply involved in the United Farm Workers (UFW) movement as a field organizer and boycott organizer for the state of Florida. Jaffe first came to the Santa Cruz area with her then-husband, Jerry Kay, who was also active in the sustainable agriculture movement. They farmed ten acres near Elkhorn Slough, and in 1976, Jaffe helped start the first farmers’ market in Santa Cruz County, at Live Oak School.After that marriage ended, Jaffe studied horticulture at Cabrillo College with Richard Merrill, and took a position with a CETA (Comprehensive Employment and Training Act) program called Project Blossom. As part of that program, she co-founded a school garden at Green Acres School in Live Oak, a semi-rural area near Santa Cruz, California. This was the genesis of the Life Lab Science Program, which grew into a groundbreaking nonprofit organization that works with schools throughout the United States to develop school gardens and curriculum for teaching science and nutrition. Jaffe served as founding executive director of the program for many years.Jaffe earned a second master’s degree in education from UC Santa Cruz, with an emphasis in agroecology. She met and married Steve Gliessman (also the subject of an oral history in this series). In 2001, they co-founded the Community Agroecology Network (CAN). CAN defines its goals as, “to help a network of rural, primarily coffee-growing communities in Mexico and Central America develop self-sufficiency and sustainable growing practices, and direct market coffee to consumers in the United States.”Jaffe is the co-author of “From Differentiated Coffee Markets Towards Alternative Trade and Knowledge Networks,” in Confronting the Coffee Crisis: Sustaining Livelihoods and Ecosystems in Mexico and Central America, and many Life Lab publications, including The Growing Classroom.Ellen Farmer interviewed Robbie Jaffe on May 5, 2007, at Jaffe's house in Santa Cruz, California. Farmer’s MA thesis (in public policy) at California State University at Monterey Bay focused on the coffee crisis. As a graduate student, she worked with Jaffe at CAN, and brought her knowledge of the economics and politics of coffee growing in Latin America to the interview
