Reseña bibliográfica : poor economics. A radical rethinking of the way to fight global poverty

El libro recientemente publicado Poor Economics -y la técnica de evaluaciones aleatorias que dan sustento a sus conclusionestienen el potencial para cambiar radicalmente la manera de diseñar políticas para combatir la pobreza en el mundo. El libro fue escrito por Abhijit Banerjee y Esther Duflo, dos jóvenes reconocidos economistas del MIT (Massachusetts Institute of Technology). Duflo, nacida en Francia y educada en el École Normale Supérieure de Paris y MIT, fue ganadora en 2010 del premio John Bates Clark al mejor economista menor de 40 años y considerada por la revista Foreign Policy como una de los 100 intelectuales más influyentes del mundo. Abhijit Banerjee educado en la Universidad de Calcuta (su ciudad de origen) y la Universidad de Harvard también es ganador de numerosos premios.

La investigación comercial como instrumento básico para el conocimiento de las actitudes del electorado: un estudio empírico en la Universidad del País Vasco

[ES] Hoy en día, cualquier partido político debe utilizar el marketing para analizar su mercado y posicionarse en el mismo con una estrategia adecuada. Para ello, el papel de la investigación comercial resulta fundamental, dado que nos permite detectar las necesidades y deseos de los electores, pudiendo el partido adoptar decisiones tendentes a satisfacerlas.

Novus orbis regionum ac insularum veteribus incognitarum : una cum tabula cosmographica & aliquot alijs consimilis argumenti libellis, quorum omnium catalogus sequenti patebit pagina : his accessit copiosus rerum memorabilium index

Esta coleção, geralmente conhecida por Grineu, foi compilada por Johann Huttich e publicada por Simon Grineu, que também escreveu e assinou o prefácio. A primeira edição, "muito e rara e de inestimável valor", segundo Borba de Moraes, foi publicada na Basiléia por Jo. Hervagium, em 1532. Dessa edição, a Biblioteca Nacional do Rio de Janeiro possui um exemplar que pertencia à Biblioteca da Ajuda. A obra foi reimpressa em Paris, em 1532, e novamente na Basiléia, em 1537. Esta edição foi acrescida da carta de Maximilianus Transilvanus, secretário de Carlos V, ao Cardeal de Salzburgo. Dentre as várias ediçoes, a mais completa é a de 1555. Relata as grandes navegações e as expedições de Cristovão Colombo, Pedro Alonso, Pinzoni, Americo Vespucio, dentre outros

“Deborah Numbers”, Coupling Multiple Space and Time Scales and Governing Damage Evolution to Failure

Two different spatial levels are involved concerning damage accumulation to eventual failure. nucleation and growth rates of microdamage nN* and V*. It is found that the trans-scale length ratio c*/L does not directly affect the process. Instead, two independent dimensionless numbers: the trans-scale one * * ( V*)including the * **5 * N c V including mesoscopic parameters only, play the key role in the process of damage accumulation to failure. The above implies that there are three time scales involved in the process: the macroscopic imposed time scale tim = /a and two meso-scopic time scales, nucleation and growth of damage, (* *4) N N t =1 n c and tV=c*/V*. Clearly, the dimensionless number De*=tV/tim refers to the ratio of microdamage growth time scale over the macroscopically imposed time scale. So, analogous to the definition of Deborah number as the ratio of relaxation time over external one in rheology. Let De be the imposed Deborah number while De represents the competition and coupling between the microdamage growth and the macroscopically imposed wave loading. In stress-wave induced tensile failure (spallation) De* < 1, this means that microdamage has enough time to grow during the macroscopic wave loading. Thus, the microdamage growth appears to be the predominate mechanism governing the failure. Moreover, the dimensionless number D* = tV/tN characterizes the ratio of two intrinsic mesoscopic time scales: growth over nucleation. Similarly let D be the “intrinsic Deborah number”. Both time scales are relevant to intrinsic relaxation rather than imposed one. Furthermore, the intrinsic Deborah number D* implies a certain characteristic damage. In particular, it is derived that D* is a proper indicator of macroscopic critical damage to damage localization, like D* ∼ (10–3~10–2) in spallation. More importantly, we found that this small intrinsic Deborah number D* indicates the energy partition of microdamage dissipation over bulk plastic work. This explains why spallation can not be formulated by macroscopic energy criterion and must be treated by multi-scale analysis.

Tunas and tuna fisheries of the World: an annotated bibliography, 1930-1953

This bibliography attempts to list, with descriptive annotations and a subject index, important literature published between 1930 and 1953 dealing with the tunas and their fisheries in all parts of the world. It is thus a continuation of Corwin's (1930) work, which extended with similar scope through 1929, and an extension of Shimada's (1951), which was limited to the biology of Pacific tunas. The tunas with which it deals are those fishes customarily so-called in commercial parlance and usually classified in the genera Thunnus, Neothunnus, Parathunnus, Germo, Katsuwonus, Euthynnus and Auxis and their various synonyms. All aspects of the biology of the tunas are dealt with, as are descriptions and histories of all types of tuna fisheries, commercial and exploratory tuna fishing methods and results, fishing gear, catch statistics, and fishery management, but processing technology, economics and marketing, folklore, and purely literary references have been excluded.
