Análisis comparativo sobre trabajo rural en la forestoindustria, las semilleras y la fruticultura (Argentina 2008-2011)

Este artículo analiza transversalmente estudios de caso sobre el trabajo rural en la Argentina entre 2008 y 2011 en unidades de producción de capital concentrado: fruticultura en el Alto Valle de Río Negro, forestación en el NO de Misiones y producción de semillas de maíz transgénico en la Zona Núcleo Cerealera. La metodología aplicada fue la etnografía multisitio. Para el análisis que se presenta en este artículo se aplicó el método comparativo, que permitió establecer continuidad entre los casos sobre la base de tres estrategias empresariales: la reducción de puestos de trabajo clásico distinguiendo producción y servicios; la ambientalización de las relaciones laborales y territorios diferenciados para la producción, y el trabajo y la residencia de los trabajadores

Relation between immersed weight and volume rates of longshore transport /

As presently used, the immersed weight rate, I sub l, is the volume rate, Q, of longshore transport, multiplied by a constant. For use in engineering problems, I sub l must be converted back to the equivalent Q. The I sub l formulation may be important where the unit weight of sand differs significantly from the unit weight of sand at the open-coast sites contributing data to the design curve. Increase in void ratio may result in a 10- to 20-percent increase in actual (as compared to predicted) shoaling volumes where sand accumulates in protected water. Void ratio should be measured in field studies of longshore transport.

Relações entre trabalho, consumo e criação de valor para as organizações: o caso Trendwatching

O objetivo desta tese é compreender, a partir das categorias trabalho e consumo, como se constituem as relações das redes de colaboração da empresa de tendências de consumo Trendwatching. No âmbito acadêmico, literatura recente revela o aparecimento de novos conceitos, como prosumer, co-criação e públicos produtivos para explicar as transformações no mundo do trabalho que envolvem cada vez mais a participação do consumidor para que o valor se realize. Dessa forma, os fundamentos teóricos que embasam esta tese providenciam elementos sobre os conceitos de valor, trabalho imaterial, consumo e suas interrelações. A coleta de dados ocorreu, em sua maior parte, na matriz da empresa em Londres durante o ano de 2015, sendo composta por: (1) realização de 31 entrevistas semi-estruturadas com spotters, funcionários e clientes da empresa; (2) observação em campo durante 3 meses, período este registrado em um diário de campo; (3) dados obtidos por meios virtuais, através do site da Trendwatching. Os dados foram analisados por meio da Análise de Conteúdo, onde, a partir de um processo de derivação, foram encontradas 49 categorias iniciais, 10 intermediárias e 3 finais. Por meio de um processo de derivação, chegou-se em 10 categorias intermediárias: (1) quem é o spotter; (2) busca de informações pelo spotter; (3) motivação e recompensa dos spotters; (4) spotters e a comunidade TW:IN; (5) formação dos spotters; (6) imagem da Trendwatching; (7) Ambiente de trabalho; (8) O que a Trendwatching vende; (9) base de dados; (10) tendências. Com estas categorias intermediárias em mãos, realizou-se novamente um processo de derivação para chegar nas categorias finais, que são: (1) spotters; (2) trabalho; (3) informação. Os resultados da pesquisa permitem mostrar que o spotter – assim chamado o indivíduo que compõe a rede a colaboração da Trendwatching – é o principal produto/serviço vendido pela empresa. A partir das categorias finais, retorna-se à pergunta de pesquisa, de modo a providenciar contribuições da tese para o campo, que são: (a) ampliar a discussão sobre criação de valor em Estudos Organizacionais, identificando diferentes conceitos e novas formas de apropriação do valor pelo capital implicados nas interações e interfaces entre trabalho e consumo; (b) demonstrar como a operacionalização da Análise de Conteúdo pode auxiliar na organização de dados empíricos virtuais (análise do site); (c) estimular que Estudos de Caso sejam, com mais frequência, realizados em organizações cujo trabalho seja imaterial por excelência.

Is the potential of Coccidoxenoides perminutus, a mealybug parasitoid, limited by climatic or nutritional factors?

The encyrtid Coccidoxenoides perminutus is a widely distributed parasitoid of citrus mealybug (Planococcus citri). Worldwide, it has been implicated in successful biocontrol in only a few widely separated localities. C perminutus contributes little to control P. citri in field situations in south-east Queensland, Australia, but invades insectary cultures and reduces mealybug populations considerably under these controlled conditions. This discrepancy between poor field performance and good performance under controlled conditions was investigated to establish whether climatic factors inhibit the field performance of this species in the biological control of P. citri. Subsequent laboratory examination of the influence of varied humidities and temperatures on the activity levels and survival of C perminutus revealed a low tolerance for high saturation deficits (i.e., low % RH at high T degreesC) with reduced reproductive output. The influence of different food sources on adult survival and reproduction was also quantified, to establish if the adverse effects of climate could be overcome by supplementing adult diet. Neither honeydew from their mealybug hosts nor nectar from Alphitonia flowers significantly enhanced parasitoid survival. A subsequent test of five nectar species revealed a significant difference in their influence on C. perminutus survival and reproduction, with only Alpinia zerumbet proving to be as suitable as honey. The floral species that proved suitable in the laboratory need to be checked for their attractiveness to C perminutus in the field and for their ability to enhance the survival and reproductive output of parasitoids. This information suggests that the prevailing dry conditions in south-east Queensland citrus-growing areas apparently impede successful biological control of P. citri by C perminutus, but possibilities are available for habitat manipulation (by providing suitable nectar sources for adult parasitoids) to conserve and enhance C perminutus activity in the field.

Why is Coccidoxenoides perminutus, a mealybug parasitoid, ineffective as a biocontrol agent - Inaccurate measures of parasitism or low adult survival?

Coccidoxenoides perminutus achieves only low levels of parasitism of its host Planococcus citri in southeast Queensland citrus. Two possible causes were investigated. Adult survival under natural conditions was assessed to determine whether providing adult food sources could enhance survival. Behavioural changes of hosts, induced by C perminutus parasitism, was also investigated to establish if parasitised P. citri move from their feeding site to seek protected shelters some distance away and are thus not accounted for in field assessments of parasitism rates. Unparasitised mealybugs placed in the field for two periods were retrieved before the effects of parasitism were manifested and parasitism rates were still low (0.3% at 5 days and 1.2% at 10 days). Levels of locomotion of P. citri exposed to C perminutus were compared with those of unexposed ones. Parasitised mealybugs, regardless of instar, undergo behavioural changes. In comparison to unparasitised controls, the mealybugs become highly active 7-14 days after exposure to wasps. All parasitised mealybugs undergo physical changes, their body becomes cylindrical, their legs go so rigid that the mealybugs become immobile, and this signifies the typical mummy appearance. All mealybugs that became mummies eventually fell from the host lemon fruit because of impaired locomotion and were caught on sticky traps that had been placed beneath the lemons. Consequently, their final site of mummification was not established. C perminutus adults provided with nectar or honey survived longer (about 5 days) in the field than those without food (about a day). Nectar from two plant species, Alpinia zerumbet and Datura candida, proved to be good sources of food for the adult wasps, and were comparable in quality to honey. The low level of parasitism achieved by C perminutus in southeast Queensland citrus thus appears to be a consequence of the short adult life and the negative effects of a harsh environment. Provision of a suitable food source (e.g., nectar) may well enhance levels of parasitism in the field. (c) 2005 Elsevier Inc. All rights reserved.

Einstein-Podolsky-Rosen correlations via dissociation of a molecular Bose-Einstein condensate

Recent experimental measurements of atomic intensity correlations through atom shot noise suggest that atomic quadrature phase correlations may soon be measured with a similar precision. We propose a test of local realism with mesoscopic numbers of massive particles based on such measurements. Using dissociation of a Bose-Einstein condensate of diatomic molecules into bosonic atoms, we demonstrate that strongly entangled atomic beams may be produced which possess Einstein-Podolsky-Rosen (EPR) correlations in field quadratures in direct analogy to the position and momentum correlations originally considered by EPR.

Enhanced energy status of corals on coastal, high-turbidity reefs

Sedimentation and high turbidity have long been considered a major threat to corals, causing world-wide concern for the health of coral reefs in coastal environments. While studies have demonstrated that sediment conditions characteristic of inshore reefs cause stress in corals, the consequences of such conditions for the physiological status of corals require testing in field situations. Here, I compare the size of energy stores (as lipid content), a proxy for physiological condition, of 2 coral species (Turbinaria mesenterina and Acropora valida) between coastal and offshore environments. Corals on coastal reefs contained 4-fold (T mesenterina) and 2-fold (A. valida) more lipid than conspecifics offshore, despite 1 order of magnitude higher turbidity levels inshore. Results were consistent across 4 sites in each environment. Reproductive investment in A. valida (a seasonal mass spawner) did not vary between environments, suggesting that the larger lipid stores in corals on coastal reefs are mainly somatic energy reserves. These results demonstrate that the environmental conditions on inshore, high-turbidity reefs do not always impact negatively on the physiology of corals. The contrasting lipid levels of T. mesenterina between environments may explain its greater success on coastal reefs.
