La Gran Depresión en Europa y en Estados Unidos (1929-1939)

[ES] En el trabajo se realiza un análisis del periodo de entreguerras, centrando su atención en el crack de la bolsa de 1929 y la Gran Depresión que le siguió. Primeramente se encuadra el contexto en la época en la que tuvo lugar, y seguidamente se entra en profundidad en el análisis del crack de la bolsa de valores de Nueva York en el año 1929, sus causas y sus consecuencias. Más tarde se habla sobre la Gran Depresión, explicando sus causas, y finalmente se recogen las consecuencias perversas que tuvo tal hecho.

Estudio de una serie musteriense de La Quina (Charente, Francia): el ejemplo de la trinchera C (excavaciones DR. L. y G. Henri-Martin)

[ES] El análisis de una serie industrial correspondiente a los cinco niveles arqueológicos de la trinchera C de La Quina (Charente, Francia), proveniente de las excavaciones del Dr. L. Henri-Martin y de G. Henri-Martin, pone de manifiesto, junto a la caracterización del conjunto estratigráfico por la presencia de raederas, el progresivo incremento de los denticulados en el devenir temporal. Este hecho asociado a otros particulares fenómenos secundarios (en el alargamiento de las formas, en la tipología de las raederas, en la elaboración del retoque, ... ) traducen una complicación diacrónica creciente en la dinámica de este complejo musteroide, presagiando, quizás, su relativa afinidad con el proceso leptolitizante de las series industriales evolucionadas del Paleolítico medio.

A questão nuclear na relação argentino-brasileira (1968-1984)

Este trabalho visa explorar a dinâmica da relação nuclear entre Argentina e o Brasil ao longo do período 1968-1984. Em particular, ele procura analisar a interação de duas dimensões desta relação. A primeira, de ordem bilateral, centra-se no estudo da rivalidade argentino-brasileira e procura medir o seu impacto tanto nas decisões nucleares de cada país como nas tentativas de estabelecer um acordo de cooperação nesta área. A segunda dimensão, de ordem internacional, analisa o impacto que teve sobre o relacionamento argentino-brasileiro a coincidente postura de ambos os países frente o regime de não proliferação nuclear (Tlatelolco e TNP) e a pressão internacional que ambos tiveram que suportar sobre os seus programas nucleares. Com esse objetivo, o trabalho se concentra em uma abordagem histórica guiada por fontes primárias (pesquisa de arquivo e entrevistas pessoais) com o objeto de reconstruir a narrativa histórica e contribuir a novas interpretações sobre o relacionamento argentino-brasileiro no período em questão em base à nova evidencia apresentada. São apresentadas quatro conclusões centrais: (1) mesmo sob uma situação de competição regional e crescente disputa geopolítica na Bacia da Prata, não houve uma corrida armamentista para a obtenção da bomba devido à natureza da rivalidade argentino-brasileira; (2) em todo momento os dois países têm incentivos para cooperar no campo nuclear por causa da sua visão compartilhada respeito à ordem nuclear global e a falta de informação perfeita sobre as atividades nucleares do outro país; (3) a dinâmica da rivalidade regional argentino-brasileira é fundamental para explicar por que, apesar de numerosas tentativas de cooperação nuclear de ambos os lados, escolhem uma lógica de não-cooperação entre as décadas de 1960 e 1970, e posteriormente, passam a uma de cooperação no começo de 1980 (4) a democratização como variável central para explicar o rapprochement nuclear teve um papel menor do que a literatura sugere.

Spatial and temporal variability in the relative contribution of king mackerel (Scomberomorus cavalla) stocks to winter mixed fisheries off South Florida

King mackerel (Scomberomorus cavalla) are ecologically and economically important scombrids that inhabit U.S. waters of the Gulf of Mexico (GOM) and Atlantic Ocean (Atlantic). Separate migratory groups, or stocks, migrate from eastern GOM and southeastern U.S. Atlantic to south Florida waters where the stocks mix during winter. Currently, all winter landings from a management-defined south Florida mixing zone are attributed to the GOM stock. In this study, the stock composition of winter landings across three south Florida sampling zones was estimated by using stock-specific otolith morphological variables and Fourier harmonics. The mean accuracies of the jackknifed classifications from stepwise linear discriminant function analysis of otolith shape variables ranged from 66−76% for sex-specific models. Estimates of the contribution of the Atlantic stock to winter landings, derived from maximum likelihood stock mixing models, indicated the contribution was highest off southeastern Florida (as high as 82.8% for females in winter 2001−02) and lowest off southwestern Florida (as low as 14.5% for females in winter 2002−03). Overall, results provided evidence that the Atlantic stock contributes a certain, and perhaps a significant (i.e., ≥50%), percentage of landings taken in the management-defined winter mixing zone off south Florida, and the practice of assigning all winter mixing zone landings to the GOM stock should

Efficiency and catch dynamics of collapsible square and conical pots used in the red king crab (Paralithodes camtschaticus) fishery

We compared the capture efficiency and catch dynamics of collapsible square and conical pots used in resource assessment and harvesting of red king crabs (Paralithodes camtschaticus [Tilesius, 1815]) in the Barents Sea. After two days of soaking, square pots caught three times as many crabs as conical pots, and their catches consisted of a higher proportion of male crabs and male crabs larger than 160 mm carapace length compared to the catches in the conical pots. Catches in the square pots did not increase as soak times were increased beyond two days, which indicates equilibrium between the rate of entries into and the rate of exits from the pots. Catches in conical pots, however, increased with increasing soak times up to eight days, the longest soak time examined in this study. These findings demonstrate the higher efficiency of square pots and the importance of understanding catch dynamics when making population assessments based on catchper-unit-of-effort data. The favorable catch characteristics and handling properties of the collapsible square pot may make this pot design suitable for other crab fisheries, as well.

Depredation of catch by bottlenose dolphins (Tursiops truncatus) in the Florida king mackerel (Scomberomorus cavalla) troll fishery

We documented depredation by bottlenose dolphins (Tursiops truncatus) in the Florida king mackerel (Scomberomorus cavalla) troll fishery. Between March and June 2003, we conducted 26 interviews of charter and commercial fishermen in Islamorada, Florida, and 23 along Florida’s east coast from Fort Pierce south to Lake Worth Inlet. All fishermen indicated they had observed bottlenose dolphins depredating bait or catch—king mackerel being the species most often taken by dolphins. During on-board observations of depredation between March and June 2003, we found that dolphins took 6% of king mackerel caught by charter fishermen and 20% of fish caught by commercial fishermen. We concluded that depredation by bottlenose dolphin occurs commonly in this fishery and has the potential to incur a significant economic cost to king mackerel fishermen. To address this concern, we conducted preliminary tests of a gear modification designed to reduce depredation in the king mackerel fishery between December 2003 and January 2004. These tests demonstrated that a modification to the outrigger planer will successfully deter bottlenose dolphins from engaging in depredation, without causing a reduction in ca

Freshwater Biological Association 1929-1979. The first fifty years

Booklet telling the story of the FBA from its founding in 1929 until its Golden Jubilee in 1979. The booklet aimed to produce a readable account of those aspects of freshwater biology that have been among the main themes of the Association's research, as well as some aspects of its history and the philosophy guiding its foundation. The publication includes many images of the FBA's work and history as well as images and illustrations on lake ecology and applied science.
