A Administração Financeira surge no início do século XIX juntamente com o movimento de consolidação das grandes empresas e a formação dos mercados nacionais americano enquanto que no Brasil os primeiros estudos ocorrem a partir da segunda metade do século XX. Desde entãoo país conseguiu consolidar alguns centros de excelência em pesquisa, formar grupo significativo de pesquisadores seniores e expandir as áreas de pesquisa no campo, contudo, ainda são poucos os trabalhos que buscam retratar as características da produtividade científica em Finanças. Buscando contribuir para a melhor compreensão do comportamento produtivo dessa área a presente pesquisa estuda sua produção científica, materializada na forma de artigos digitais, publicados em 24 conceituados periódicos nacionais classificados nos estratos Qualis/CAPES A2, B1 e B2 da Área de Administração, Ciências Contábeis e Turismo. Para tanto são aplicadas a Lei de Bradford, Lei do Elitismo de Price e Lei de Lotka. Pela Lei de Bradford são identificadas três zonas de produtividade sendo o núcleo formado por três revistas, estando uma delas classificada no estrato Qualis/CAPES B2, o que evidencia a limitação de um recorte tendo como único critério a classificação Qualis/CAPES. Para a Lei do Elitismo de Price, seja pela contagem direta ou completa, não identificamos comportamento de uma elite semelhante ao apontado pela teoria e que conta com grande número de autores com apenas uma publicação.Aplicando-se o modelo do Poder Inverso Generalizado, calculado por Mínimos Quadrados Ordinários (MQO), verificamos que produtividade dos pesquisadores, quando feita pela contagem direta, se adequa àquela definida pela Lei de Lotka ao nível de α = 0,01 de significância, contudo, pela contagem completa não podemos confirmar a hipótese de homogeneidade das distribuições, além do fato de que nas duas contagens a produtividade analisada pelo parâmetro n é maior que 2 e, portanto, a produtividade do pesquisadores de finanças é menor que a defendida pela teoria.

In the context of future scenarios of progressive accumulation of anthropogenic CO2 in marine surface waters, the present study addresses the effects of long-term hypercapnia on a Mediterranean bivalve, Mytilus galloprovincialis. Sea-water pH was lowered to a value of 7.3 by equilibration with elevated CO2 levels. This is close to the maximum pH drop expected in marine surface waters during atmosextracellular pHric CO2 accumulation. Intra- and extracellular acid-base parameters as well as changes in metabolic rate and growth were studied under both normocapnia and hypercapnia. Long-term hypercapnia caused a permanent reduction in haemolymph pH. To limit the degree of acidosis, mussels increased haemolymph bicarbonate levels, which are derived mainly from the dissolution of shell CaCO3. Intracellular pH in various tissues was at least partly compensated; no deviation from control values occurred during long-term measurements in whole soft-body tissues. The rate of oxygen consumption fell significantly, indicating a lower metabolic rate. In line with previous reports, a close correlation became evident between the reduction in extracellular pH and the reduction in metabolic rate of mussels during hypercapnia. Analysis of frequency histograms of growth rate revealed that hypercapnia caused a slowing of growth, possibly related to the reduction in metabolic rate and the dissolution of shell CaCO3 as a result of extracellular acidosis. In addition, increased nitrogen excretion by hypercapnic mussels indicates the net degradation of protein, thereby contributing to growth reduction. The results obtained in the present study strongly indicate that a reduction in sea-water pH to 7.3 may be fatal for the mussels. They also confirm previous observations that a reduction in sea-water pH below 7.5 is harmful for shelled molluscs.

El objetivo de este estudio de caso es describir y analizar los intereses nacionales desde la concepción de India y Noruega durante el contexto histórico del conflicto en Sri Lanka, además examinar cómo estos intereses influenciaron la consolidación de las estrategias y tácticas de negociación. La hipótesis aprobar es que las mediaciones de India y Noruega se desarrollan de forma distinta debido a sus intereses, sin embargo, ambas lograron formas de entendimiento entre el Gobierno de esrilanqués y el Grupo Insurgente Tigres de Liberación de la Tierra Tamil (LTTE). Para esto, se revisan los límites de las mediaciones conforme a los intereses. Siguiendo distintas perspectivas académicas del realismo, neorrealismo y cientificismo se utilizan distintos conceptos desarrollados por Hans Morgentau, Robert Osgood, Johan Galtung, Oliver Ramsbothan, Saddia Touval e Isak Svensson. Desde el método descriptivo histórico y análisis cuantitativo se describen los intereses nacionales y su influencia en las mediaciones que se llevaron a cabo en Sri Lanka.

El objetivo de esta monografía es interpretar, desde la biopolítica, la construcción de un racismo de Estado en Alemania a través de la política inmigratoria bajo el mandato de Angela Merkel (2005-2014). Por medio de tres apartados se presenta de manera organizada la teoría de la biopolítica desarrollada por Michel Foucault, con sus postulados y conceptos principales, resaltando el concepto de racismo de Estado. También se enuncia de manera breve la historia de la inmigración en Alemania, su ley de inmigración actual y la ley de nacionalidad. De esta forma, se puede analizar que en Alemania se ha construido un racismo de Estado, desde la visión teórica de la biopolítica de Foucault, a través de la consolidación de la política inmigratoria vigente en dicho Estado (2005-2014), que reúne el tema de la migración internacional regular.

El trabajo de investigación es un estudio de caso que pretende analizar la forma en que factores del contexto institucional y la capacidad de influencia de ciertos actores se reflejan en la discusión y aprobación de la Ley 975 de 2005. Factores del contexto institucional y la capacidad de influencia sobre las posiciones asumidas por los actores políticos y sociales en las diferentes etapas del proceso legislativo y sobre las decisiones que se tomaron para la aprobación de la Ley, en torno a dos elementos fundamentales de ésta que son el delito político y la rebaja de penas. Para ello, se tiene en cuenta el enfoque neo-institucional y el concepto de agencia.

The BRITE Project undertook six innovation case studies of building and construction projects in 2005. The purpose of the program was to demonstrate the benefits of innovation and highlight the nature of successful implementation strategies. The cases were selected following a public call in industry magazines across Australia, which resulted in approximately 50 nominations. The six selected case studies resulted in three prominent contributions to knowledge

Alvin Toffler’s image of the prosumer (1970, 1980, 1990) continues to influence in a significant way our understanding of the user-led, collaborative processes of content creation which are today labelled “social media” or “Web 2.0”. A closer look at Toffler’s own description of his prosumer model reveals, however, that it remains firmly grounded in the mass media age: the prosumer is clearly not the self-motivated creative originator and developer of new content which can today be observed in projects ranging from open source software through Wikipedia to Second Life, but simply a particularly well-informed, and therefore both particularly critical and particularly active, consumer. The highly specialised, high end consumers which exist in areas such as hi-fi or car culture are far more representative of the ideal prosumer than the participants in non-commercial (or as yet non-commercial) collaborative projects. And to expect Toffler’s 1970s model of the prosumer to describe these 21st-century phenomena was always an unrealistic expectation, of course. To describe the creative and collaborative participation which today characterises user-led projects such as Wikipedia, terms such as ‘production’ and ‘consumption’ are no longer particularly useful – even in laboured constructions such as ‘commons-based peer-production’ (Benkler 2006) or ‘p2p production’ (Bauwens 2005). In the user communities participating in such forms of content creation, roles as consumers and users have long begun to be inextricably interwoven with those as producer and creator: users are always already also able to be producers of the shared information collection, regardless of whether they are aware of that fact – they have taken on a new, hybrid role which may be best described as that of a produser (Bruns 2008). Projects which build on such produsage can be found in areas from open source software development through citizen journalism to Wikipedia, and beyond this also in multi-user online computer games, filesharing, and even in communities collaborating on the design of material goods. While addressing a range of different challenges, they nonetheless build on a small number of universal key principles. This paper documents these principles and indicates the possible implications of this transition from production and prosumption to produsage.
