The performance of 32 tropical rainforest and eucalypt tree species grown in private, mixed species plantations was examined. There were two objectives: 1) to summarise the growth of species by soil and rainfall classes, 2) to investigate the degree of variability in growth rates with respect to environmental variables. Data were collected from 112 plots established in the Community Rainforest Reforestation Program (CRRP) plantations across sites in the humid tropics of central and north Queensland. Sites ranged from sea level to 1160 m above sea level, with annual rainfall from 800 mm to 4300 mm, on soils derived from basalt, metamorphic and granite parent material. Species performance was significantly related to climatic and edaphic variables but the strength of these relationships differed among taxa.

Esta dissertação surgiu de um projeto realizado na rede oficial de ensino do município de Santo André (SP) no período de agosto a dezembro de 2008 junto aos professores inscritos no curso Formação sobre culturas de língua espanhola e suas possibilidades no trabalho pedagógico . Tal projeto teve como aspecto fundamental inserir os professores dos anos iniciais na língua e na cultura espanhola, assim como na hispano-americana, direcionando-os a adquirirem uma visão globalizada das novas tendências existentes na aquisição de uma segunda língua. O curso permitiu aos professores compartilharem experiências e aprofundarem seus estudos na integração cultural e linguística, por meio de metodologias e técnicas facilitadoras, adequadas à faixa etária dos seus alunos crianças de 6 a 10 anos. A partir desse projeto, a pesquisa desenvolvida procurou teóricos para estruturar o trabalho, cuja pergunta norteadora possibilidades de introduzir o ensino de uma língua estrangeira no caso, o espanhol , nos primeiros anos do Ensino Fundamental I. Como no Brasil, não há um grande número de professores habilitados no ensino da língua espanhola, questionou-se sobre tal possibilidade, considerando ainda que as escolas municipais, que são as escolas que oferecem o Ensino Fundamental I, não apresentam em seu currículo o ensino de língua estrangeira. Com base em teóricos que apontam diferentes caminhos para se aprender uma língua estrangeira e frente ao exposto, o estudo buscou analisar os depoimentos e observações ocorridos na execução dos projetos individuais, que professores da rede municipal também sujeitos desta pesquisa elaboraram durante o curso. A análise dos questionários, da entrevista e do depoimento realizados junto a onze desses sujeitos possibilitou traçar o perfil de sua formação, da sua atuação e da sua trajetória profissional. Os dados colhidos foram analisados tendo como referencial teórico Jacques Rancière (2007) em referência a Jacotot e seu Mestre ignorante , que aborda conceitos de explicação, igualdade e vontade, submetendo-os à análise de conteúdo. Nesse contexto, foram extraídas as reflexões sobre as possibilidades de prática pedagógica na vivência dos professores durante a execução do projeto. O estudo considerou, após esta experiência, que existe a possibilidade de ministrar uma formação continuada de língua espanhola a professores que já atuem com alunos dos anos iniciais.(AU)

Purpose -The main aim of this paper is to examine the underlying drivers for the development and subsequent discontinuation of stand-alone corporate social responsibility (CSR) reporting in a multinational subsidiary in Bangladesh. Design/Methodology/Approach - The research approach employed for this purpose is a case study using evidence from a series of in depth interviews conducted during the period 2002-2010. Interview data is supplemented by examining other sources of information including annual reports, stand-alone social reports and relevant newspaper articles during the study period. Findings - It appears that the stand-alone CSR reporting process was initiated to give the subsidiary a formal space in which to legitimise its activities in Bangladesh where both tobacco control regulation and a strong anti-tobacco movement were gaining momentum. At the start of the process in 2002 corporate interviewees were very receptive of this initiative and strongly believed that it would not be a one off exercise. However, in the face of subsequent significant national policy shifts concerning tobacco control, irreconcilable stakeholder demands and increasing criticism of the CSR activities of the organisation at home and abroad the process was brought to an abrupt end in 2009. Research Limitations/Implications - The paper has a number of implications for policy makers concerning the future prospects for stand-alone social/sustainability reporting as a means of enhancing organisational transparency and accountability. In addition the paper discusses a number of theoretical implications for the development of legitimacy theory. Originality/value - Using the lens of legitimacy the paper theorises the circumstances leading to the initiation and subsequent cessation of CSR reporting in the organisation concerned. As far as we know this is the first study which theorises and provides significant fieldwork based empirical evidence regarding the discontinuation of stand-alone social reporting by a multinational company operating in a developing country. Thus, it extends previous desk-based attempts at using legitimacy theory to explain a decrease (or discontinuity) in CSR disclosures by de Villiers and van Staden (2006) and Tilling and Tilt (2010).

This paper explores the connection between leadership behaviors and employee engagement to build a proposed conceptual model. A conceptual link between employee needs (Herzberg, 1959; Maslow, 1970), emotional intelligence (Goleman, 1998), and transformational leadership (Bass, 1985) is discussed.

This dissertation focused on developing an integrated surface – subsurface hydrologic simulation numerical model by programming and testing the coupling of the USGS MODFLOW-2005 Groundwater Flow Process (GWF) package (USGS, 2005) with the 2D surface water routing model: FLO-2D (O’Brien et al., 1993). The coupling included the necessary procedures to numerically integrate and verify both models as a single computational software system that will heretofore be referred to as WHIMFLO-2D (Wetlands Hydrology Integrated Model). An improved physical formulation of flow resistance through vegetation in shallow waters based on the concept of drag force was also implemented for the simulations of floodplains, while the use of the classical methods (e.g., Manning, Chezy, Darcy-Weisbach) to calculate flow resistance has been maintained for the canals and deeper waters. A preliminary demonstration exercise WHIMFLO-2D in an existing field site was developed for the Loxahatchee Impoundment Landscape Assessment (LILA), an 80 acre area, located at the Arthur R. Marshall Loxahatchee National Wild Life Refuge in Boynton Beach, Florida. After applying a number of simplifying assumptions, results have illustrated the ability of the model to simulate the hydrology of a wetland. In this illustrative case, a comparison between measured and simulated stages level showed an average error of 0.31% with a maximum error of 2.8%. Comparison of measured and simulated groundwater head levels showed an average error of 0.18% with a maximum of 2.9%.

Increased device density, switching speeds of integrated circuits and decrease in package size is placing new demands for high power thermal-management. The convectional method of forced air cooling with passive heat sink can handle heat fluxes up-to 3-5W/cm2; however current microprocessors are operating at levels of 100W/cm2, This demands the usage of novel thermal-management systems. In this work, water-cooling systems with active heat sink are embedded in the substrate. The research involved fabricating LTCC substrates of various configurations - an open-duct substrate, the second with thermal vias and the third with thermal vias and free-standing metal columns and metal foil. Thermal testing was performed experimentally and these results are compared with CFD results. An overall thermal resistance for the base substrate is demonstrated to be 3.4oC/W-cm2. Addition of thermal vias reduces the effective resistance of the system by 7times and further addition of free standing columns reduced it by 20times.

The Tara Oceans Expedition (2009-2013) was a global survey of ocean ecosystems aboard the Sailing Vessel Tara. It carried out extensive measurements of evironmental conditions and collected plankton (viruses, bacteria, protists and metazoans) for later analysis using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set includes properties of seawater, particulate matter and dissolved matter that were measured from discrete water samples collected with Niskin bottles during the 2009-2013 Tara Oceans expedition. Properties include pigment concentrations from HPLC analysis (10 depths per vertical profile, 25 pigments per depth), the carbonate system (Surface and 400m; pH (total scale), CO2, pCO2, fCO2, HCO3, CO3, Total alkalinity, Total carbon, OmegaAragonite, OmegaCalcite, and dosage Flags), nutrients (10 depths per vertical profile; NO2, PO4, N02/NO3, SI, quality Flags), DOC, CDOM, and dissolved oxygen isotopes. The Service National d'Analyse des Paramètres Océaniques du CO2, at the Université Pierre et Marie Curie, determined CT and AT potentiometrically. More than 200 vertical profiles of these properties were made across the world ocean. DOC, CDOM and dissolved oxygen isotopes are available only for the Arctic Ocean and Arctic Seas (2013).
