Gestão da informação na Embrapa Amazônia Oriental: uso relativo versus uso efetivo da literatura técnico-científica agropecuária periódica - 1990-1999

Análise bibliométrica de uso da coleção de periódicos, evidenciando o papel fundamental que as bibliotecas da Embrapa desempenham na estrutura organizacional e na estratégia competitiva da empresa. Bibliotecas formam a interface entre a geração e a disseminação do processo de pesquisa, desenvolvimento e inovações ( PD&I).Resultados apontaram que 77,05% dos títulos de periódicos utilizados efetivamente encontram-se no Catálogo de Periódicos da Embrapa (CCPE), dos quais 81,83% pertencem ao Catálogo de Periódicos da Unidade, demonstrando a eficácia do acervo da biblioteca para as atividades de PD&I na Unidade, no período estudado. Dos títulos estrangeiros adquiridos por compra, 20% atingiram um indicador de freqüência de uso no período > 10, merecendo priorização de manuteção de assinaturas e processos de preservação.

Consideracions sobre l'estudi i classificació de les comunitats arvenses

La clasificación y el estudio de las comunidades arvenses presentan en ocasiones problemas metodológicos y conceptuales compartidos, en gran manera. con la vegetación ruderal. Una parte de estos problemas tiene su origen eh los cambios profundos que han sufrido los sistemas de cultivo durante los últimos decenios, después de siglos de tratamientos agricolas relativamente homogéneos. También en la introducción continuada y creciente de plantas alóctonas, muchas de las cuales hallan acomodo en los cultivos. Todo ello confluye causando transformaciones diversas en la vegetación arvense.

Looking Back: Historical Hall, 1899-1904; State Historical, Memorial and Art Building, 1905-1999; Ola Babcock Miller Building, 1999-Present, June 2013

For more than 80 years, visitors to the Iowa State Historical, Memorial, and Art Building were treated to the state’s collection of historic documents, literature, portraits, and historical, geological, and archeological artifacts. Those who visited might have memories of the spectacular sand paintings by Iowan Andrew Clemens, the variety of taxidermy Iowa animals, the pioneer Conestoga wagon in the basement, the biplane hanging from the dome ceiling, the odd display by the medical library of things removed from stomachs, or the Native American display on the third floor. This booklet is a look back at the origins of the museum. It includes some of the Historical Department reports, legislation passed by the general assembly, newspaper and magazine articles, and photographs pertaining to the museum and library. It is not intended to be an exhaustive review and documentation of displays and exhibits. It is a brief overview of the building’s history and some photographs that may bring back memories, for some, of a field trip as a student. This booklet has been created from a variety of source materials: photographs, newspaper articles, and various reports. The following have contributed: State Library of Iowa, Iowa State Historical Society, the Iowa Judicial Branch, Susan Wallace, Helen Dagley, Barb Corson, Jerome Thompson, Pam Rees, Georgiann Fischer, and Jason Mrachina.

Response of Iowa Pavements to Heavy Agricultural Loads, HR-1075, 1999

Iowa's county road system includes several thousands of miles of paved roads which consist of Portland cement concrete (PCC) surfaces, asphalt cement concrete (ACC) surfaces, and combinations of thin surface treatments such as seal coats and slurries. These pavements are relatively thin pavements when compared to the state road system and therefore are more susceptible to damage from heavy loads for which they were not designed. As the size of the average farm in Iowa has increased, so have the size and weights of implements of husbandry. These implements typically have fewer axles than a truck hauling the same weight would be required to have; in other words, some farm implements have significantly higher axle weights than would be legal for semi-trailers. Since stresses induced in pavements are related to a vehicle's axle weight, concerns have been raised among county and state engineers regarding the possible damage to roadway surfaces that could result from some of these large implements of husbandry. Implements of husbandry on Iowa's highway system have traditionally not been required to comply with posted weight embargo on bridges or with regulations regarding axle-weight limitations on roadways. In 1999, with House File 651, the Iowa General Assembly initiated a phased program of weight restrictions for implements of husbandry. To help county and state engineers and the Iowa legislature understand the effects of implements of husbandry on Iowa's county roads, the following study was conducted. The study investigated the effects of variously configured grain carts, tank wagons, and fence-line feeders on Iowa's roadways, as well as the possible mitigating effects of flotation tires and tracks on the transfer of axle weights to the roadway. The study was accomplished by conducting limited experimental and analytical research under static loading conditions

Human capital spillovers, productivity and regional convergence in Spain

This paper analyses the differential impact of human capital, in terms of different levels of schooling, on regional productivity and convergence. The potential existence of geographical spillovers of human capital is also considered by applying spatial panel data techniques. The empirical analysis of Spanish provinces between 1980 and 2007 confirms the positive impact of human capital on regional productivity and convergence, but reveals no evidence of any positive geographical spillovers of human capital. In fact, in some specifications the spatial lag presented by tertiary studies has a negative effect on the variables under consideration.
