John Nathan Cobb (1868–1930): Founding Director of the College of Fisheries, University of Washington, Seattle

John Nathan Cobb (1868–1930) became the founding Director of the College of Fisheries, University of Washington, Seattle, in 1919 without the benefit of a college education. An inquisitive and ambitious man, he began his career in the newspaper business and was introduced to commercial fisheries when he joined the U.S. Fish Commission (USFC) in 1895 as a clerk, and he was soon promoted to a “Field Agent” in the Division of Statistics, Washington, D.C. During the next 17 years, Cobb surveyed commercial fisheries from Maine to Florida, Hawaii, the Pacific Northwest, and Alaska for the USFC and its successor, the U.S. Bureau of Fisheries. In 1913, he became editor of the prominent west coast trade magazine, Pacific Fisherman, of Seattle, Wash., where he became known as a leading expert on the fisheries of the Pacific Northwest. He soon joined the campaign, led by his employer, to establish the nation’s first fisheries school at the University of Washington. After a brief interlude (1917–1918) with the Alaska Packers Association in San Francisco, Calif., he was chosen as the School’s founding director in 1919. Reflecting his experience and mindset, as well as the University’s apparent initial desire, Cobb established the College of Fisheries primarily as a training ground for those interested in applied aspects of the commercial fishing industry. Cobb attracted sufficient students, was a vigorous spokesman for the College, and had ambitions plans for expansion of the school’s faculty and facilities. He became aware that the College was not held in high esteem by his faculty colleagues or by the University administration because of the school’s failure to emphasize scholastic achievement, and he attempted to correct this deficiency. Cobb became ill with heart problems in 1929 and died on 13 January 1930. The University soon thereafter dissolved the College and dismissed all but one of its faculty. A Department of Fisheries, in the College of Science, was then established in 1930 and was led by William Francis Thompson (1888–1965), who emphasized basic science and fishery biology. The latter format continues to the present in the Department’s successor, The School of Aquatic Fisheries and Science.

Educação nas redes: professores em cotidianos de produções televisivas

O que fazem profissionais de educação numa produção televisiva? Nesta pesquisa, por meio de 'conversas' com praticantespensantes que atuam em produção de TV, e no uso de outros documentos (programas editados, argumentos, textos e roteiros), busco responder a essa pergunta e compreender as redes de conhecimentos e significações relativas aos espaçostempos de ação desses profissionais, entendidos como entre-lugares de educação e comunicação. A pesquisa, na perspectiva dos estudos com os cotidianos, se articula ao GRPESQ Currículo, redes educativas e imagens, do Laboratório Educação e Imagem/ProPEd/UERJ, e busca apoio em conversas/narrativas com/de professores que trabalharam/trabalham em televisão em especial, no programa Salto para o Futuro integrando a equipe de educação da TV Escola (MEC), ou atuando como consultores de séries temáticas. Sobre o assunto, também foram ouvidos responsáveis pela assessoria pedagógica dos canais Encuentro e Pakapaka, na Argentina, em doutorado-sanduíche, com o apoio da Capes. Como fundamentação teórica, além de pesquisas com os cotidianos, a partir de textos de Michel de Certeau, de Nilda Alves e de Inês Barbosa de Oliveira, dos quais emergem algumas das noções que permeiam essa investigação, ressalto a contribuição de autores da sociologia, como Pierre Bourdieu e Boaventura de Sousa Santos e, ainda, de represe ntantes dos chamados estudos culturais, entre eles Jesús Martín-Barbero, Nestor Canclini, Stuart Hall, Homi Bhabha entre outros. A questão do outro, da alteridade, que permeia a tese, em sua tessitura com narrativas e imagens, busca inspiração também nos escritos e em conversas com Carlos Skliar e nos textos de Jorge Larrosa. As conclusões possíveis destacam a importância das ações desses profissionais (professores) nesses espaçostempos televisivos.

Liquid crystal over silicon device characteristics for holographic projection of high-definition television images.

We discuss some fundamental characteristics of a phase-modulating device suitable to holographically project a monochrome video frame with 1280 x 720 resolution. The phase-modulating device is expected to be a liquid crystal over silicon chip with silicon area similar to that of commercial devices. Its basic characteristics, such as number of pixels, bits per pixel, and pixel dimensions, are optimized in terms of image quality and optical efficiency. Estimates of the image quality are made from the noise levels and contrast, while efficiency is calculated by considering the beam apodization, device dead space, diffraction losses, and the sinc envelope.
