A monetary mechanism for sharing capital: Diamond and Dybvig meet Kiyotaki and Wright

A model is presented in which banks accept deposits of fiat money and intermediate capital. Alt though theories about the coexistence of money and credit are inherently difficult, the model offers a simple explanation for the dual role of financial institutions: Banks are well monitored, and can credibly allow fiat-money withdraws to whom needs its, thus qualifying to become safe brokers of idle capital. The model shares some features with those of Diamond and Dybvig (1983) and Kiyotaki and Wright (1989).

A monetary mechanism for sharing capital: Diamond and Dybvig meet Kiyotaki and Wright

Historically, payment systems and capital intermediation interact. Friedman (1959), and many observers of bank instabilities, have ad- vocated separating depositary from credit institutions. His proposal meets today an ever-increasing provision of inside money, and a short- age of monetary models of bank intermediation. In this paper, we eval- uate the proposal from a new angle, with a model in which isolating a safe payments system from commercial intermediation undermines information complementarities in banking activities. Some features of the environment resemble the models in Diamond and Dybvig (1983), and Kiyotaki and Wright (1989).

A personagem Bigger Thomas na obra de Richard Wright e a construção de identidade afro-americana

This paper analyzes the character Bigger Thomas Native Son’s American novel published in 1940 by African-American author Richard Wright. Through this character we try to study more the post-slavery racial issue in a country where racial segregation was legally sustained and how this issue was reflected in society and identity formation of their native sons African-American

Quatro Desenhos de Frank Lloyd Wright

O objetivo deste trabalho é discutir aspectos do processo de projeto e sua representação gráfica, num momento em que softwares de projeto 3D vem se tornando hegemônicos na prática do arquiteto e no ensino de arquitetura, em contraponto às práticas de desenho em prancheta. Os motivos e circunstâncias não são objeto do trabalho, cujo foco está numa prática de projeto e representação gráfica 2D, mas que tem muito a contribuir para o debate do quadro acima: os desenhos de projeto de Frank Lloyd Wright. Casos de estudo: quatro pranchas desenhadas por FLLW. É importante notar que, no vasto quadro da historiografia wrightiana, análises e interpretações originais, pioneiras, da arquitetura vem surgindo nas últimas décadas, mas ainda há poucos textos sobre desenhos e representação gráfica do arquiteto. Este constitui uma primeira aproximação do autor acerca de tema que oferece abrangente potencial. São exemplos em que, na relação imagem-objeto, a representação bidimensional constrói o projeto tridimensional. A arquitetura emerge como experimentação sem cair na especulação formal. Demonstram uma prática mais lenta, reflexiva e laboriosa do que a oferecida pelos software 3D atuais – mas onde cada traço, textura e grafismo implica um significado de espaço e materialidade.

Pliocene Paleoenvironment and Antarctic Ice Sheet Behavior: Evidence from Wright Valley

Investigations in Wright Valley, adjacent to the Transantarctic Mountains in East Antarctica, shed light on the question of whether high-latitude Pliocene climate was warm enough to cause widespread deglaciation of the East Antarctic craton with a concurrent Magellanic moorland-like environment. If Pliocene age diatoms, presently in glaciogenic deposits high in the Transantarctic Mountains, had come from seaways on the East Antarctic craton, an expanding Late Pliocene ice sheet must have first eroded them from marine sediments and then deposited the diatoms at their present high-altitude locations. This hypothetical expanding glacier would have had to have come through Wright Valley. Glacial drift sediments from the central Wright Valley were mapped, sampled, analyzed, and Ar-40/Ar-39 whole rock dated. Our evidence indicates that an East Antarctic outlet glacier has not expanded through Wright Valley, and hence cannot have overridden the Dry Valleys sector of the Transantarctic Mountains, any time in the past 3.8 myr. Rather, there was only moderate Pliocene expansion of local cola-based alpine glaciers and continuous cold-desert conditions in Wright Valley. Persistence of a cold-desert paleoenvironment implies that the sector of the East Antarctic Ice Sheet adjacent to Wright Valley has remained relatively stable without melting ablation zones since at least 3.8 Ma, in Early Pliocene time. A further implication is that Antarctic Ice Sheet behavior in the Pliocene was much like that in the Quaternary, when the ice sheet consisted of a stable, terrestrial core in East Antarctica and a dynamic, marine-based appendage in West Antarctica.

Glacial Lake Wright, a High-Level Antarctic Lake During the LGM and Early Holocene

We report evidence of a large proglacial lake (Glacial Lake Wright) that existed in Wright Valley in the McMurdo Dry Valleys region of Antarctica at the last glacial maximum (LGM) and in the early Holocene. At its highstands, Glacial Lake Wright would have stretched 50 km and covered c. 210 km(2). Chronology for lake-level changes comes from 30 AMS radiocarbon dates of lacustrine algae preserved in deltas, shorelines, and glaciolacustrine deposits that extend up to 480 m above present-day lakes. Emerging evidence suggests that Glacial Lake Wright was only one of a series of large lakes to occupy the McMurdo Dry Valleys and the valleys fronting the Royal Society Range at the LGM. Although the cause of such high lake levels is not well understood, it is believed to relate to cool, dry conditions which produced fewer clouds, less snowfall, and greater amounts of absorbed radiation, leading to increased meltwater production.
