Research assessed early stages of calcareous soil reclamation along the TMX-Anchor Loop pipeline through Jasper National Park. Calcareous soils are low in nutrients and highly prone to erosion after disturbances. Four sites were established in each of five calcareous soils, and divided into three pipeline right-of-way areas; work, trench and spoil. Ten amendment treatments, established within each right-of-way areaincluded a control and combinations of wood chips, fertilizer and compost with some plots having amendments incorporated. Wood chip treatments decreased availability of soil nutrients, with small plants contributing to high vegetation densities and low cover. Compost treatments increased soil nutrients and aided large plant establishment, creating lower plant densities and higher cover. Light application rates were most successful, with higher native plant densities and cover in relation to heavy application rates, which encouraged robust non-native plants. Pipeline right-of-way areas had no overall impact on early reclamation success. / Land Reclamation and Remediation

The ingestion of foods with TMX residues with a limit of 0.02 mg.Kg-1 (allowed by ANVISA) causes acute intoxications (headache, abdominal pain, nausea, vomiting) and in cases of chronic intoxication, the challenge is to relate the developed disease to the insecticide exposure over the time. It is evident the problem of the use of pesticides in Brazilian agriculture and consequently the contamination of food and water. It is necessary to develop accurate methods for quantification of these pesticides to monitor agricultural contamination and food quality control. Chromatographic methods are the most widely used in the detection of TMX, but are expensive and require a prior preparation of the sample. Electrochemical methods are also used as a high sensitivity method for determination of TMX, both in commercial formulations and in real environmental samples. Until the present work, no electroanalytical method has been using boron doped diamond electrodes (BDD) for the determination of (TMX) has not been described in the literature. In this way, this work had the objective of determining the TMX insecticide using electrodes (DDB5000 ppm and DDB8000 ppm) by means of the Cathodic Stripping Voltammetry technique coupled with Square Wave Voltammetry (CSV/SWV). The proposed method was applied in natural water samples from the parameters optimized as: Deposition Time (Dt); Deposition Potential (Ed); Frequency (f) and amplitude (a), in an electrochemical cell containing the supporting electrolyte (KCl 1M, pH = 6.4). For the DDB5000 ppm electrode, the limit of detection (LD) and limit quantification (LQ) in the standard solution were 10 μmol/L and 30 μmol/L, respectively. For the DDB8000 ppm electrode these values were 1.5 μmol/L and 4.5 μmol/L, respectively. Tests were also carried out on water samples collected from the Moraes river stream in Maués - AM. Thus, the concentrations found using the methodology proposed for TMX were 9.6 μmol/L at point 01, at point 02 it was 5.0 μmol/L and at 2.5 μmol/L at point 03. Thus, the electrode with higher doping level, revealed to be able to determine TMX in natural samples waters. / O tiametoxam (TMX) é um inseticida sistêmico, granulado, solúvel considerado altamente tóxico para insetos e menos tóxico para animais. A ingestão de alimentos com resíduos de TMX com o limite acima de 0,02 mg.Kg-1 permitido pela ANVISA, provocam intoxicações agudas (dor de cabeça, dor abdominal, enjôos, vômitos) e nos casos de intoxicação crônica, o desafio é conseguir relacionar a doença desenvolvida com a exposição ao inseticida ao longo do tempo. Fica evidente a problemática da utilização de agrotóxicos na agricultura brasileira e consequentemente a contaminação dos alimentos e águas. Torna-se, assim, necessário o desenvolvimento de métodos precisos na quantificação desses agrotóxicos para monitorar a contaminação agrícola e no controle de qualidade dos alimentos. Os métodos cromatográficos são os mais utilizados na detecção do TMX, mas são caros e exigem preparação prévia da amostra. Também se usa os métodos eletroquímicos por ser um método de alta sensibilidade para determinação do TMX, tanto em formulações comerciais como em amostras ambientais reais. Até o presente trabalho, não foi descrito na literatura nenhum método eletroanalítico utilizando eletrodo de diamante dopado com boro (DDB) para a determinação do (TMX). Desta forma, este trabalho teve como objetivo a determinação do inseticida TMX utilizando eletrodos (DDB5000 ppm e DDB8000 ppm) por meio da técnica de Voltametria de Redissolução Catódica acoplada com a Voltametria de Onda Quadrada (VRC/VOQ). O método proposto foi aplicado nas amostras de águas naturais a partir dos parâmetros otimizados como: Tempo de Deposição (Td); Potencial de Deposição (Ed); Frequência (f) e amplitude (a), em uma célula eletroquímica que continha o eletrólito suporte (KCl 1M, pH= 6,4). Para o eletrodo DDB5000 ppm, o limite de detecção (LD) e limite quantificação (LQ) na solução padrão foram de 10 μmol/L e 30 μmol/L, respectivamente. Estes valores para o eletrodo DDB8000 ppm foram de 1,5 μmol/L e 4,5 μmol/L, respectivamente. Também se realizou ensaios em amostras de águas coletadas do igarapé do rio Moraes em Maués - AM. De modo que as concentrações encontradas por meio da metodologia proposta para o TMX foi den9,6 μmol/L no ponto 01, para o ponto 02 foi de 5,0 μmol/L e de 2,5 μmol/L no ponto 03. Deste modo, o eletrodo de maior dopagem, revelou ser capaz de determinar TMX em amostras de águas naturais.

[pt] Este estudo analisou a influência exercida pela liderança compartilhada na inovação, investigando como a criatividade e o Team-Member-Exchange (TMX) explicariam esta conexão, e avaliando os efeitos da liderança compartilhada na capacidade absortiva e na eficácia das equipes. Pesquisas internacionais indicam que a liderança compartilhada permite às organizações superarem a complexidade de seus processos produtivos e construírem uma consistente e continua inovação, mas ainda são poucos os estudos realizados no Brasil. Desta forma, o presente estudo engloba uma análise no nível de grupo e tem como base uma amostra de 222 colaboradores e 19 líderes formais, permitindo investigar 76 grupos que atuam no segmento de Pesquisa e Desenvolvimento (P&D) de uma organização brasileira do ramo de energia. Os resultados sugerem uma influencia positiva da liderança compartilhada na capacidade absortiva e na eficácia global das equipes e confirmam os efeitos mediadores da criatividade, sugerindo que a mesma parece ser uma via relevante pela qual a liderança compartilhada promove a inovação dentro da organização. / [en] This study has analyzed the influence of shared leadership in innovation, investigating how creativity and Team-Member-Exchange (TMX) explain this connection and evaluating the effects of shared leadership on absorptive capacity and effectiveness of the teams. International research indicates that shared leadership enables organizations to overcome the complexity of its production processes and build a consistent and continuous innovation, but there are few studies in Brazil. Thus, the present study includes a descriptive analysis at the group level and is based on a sample of 222 employees and 19 formal leaders, allowing the investigation of 76 groups working in the Research and Development (R&D) of an energy Brazilian organization. The results suggests a positive influence of shared leadership in absorptive capacity and overall effectiveness of teams and confirm the mediating effects of creativity, suggesting that it appear to be a relevant route where shared leadership further innovation within the organization.

There is an increasing interest in within-group agreement in organizations, in response to evidence that agreement is predictive of various outcomes of interest. The model in this study suggests that within-group agreement on perceptions of the work environment is predicted indirectly by the quality of exchange relationships, specifically team-member exchange (TMX), leader-member exchange (LMX), social interaction and work interdependence, through the mediation of social influence, and directly by demographic homogeneity. Chan's (1998) typology of composition models was used to appropriately conceptualize the variables at the group level.Results suggest that average high quality LMX relationships are predictive of within-group agreement, and that high quality relationships within the team are predictive of perceptions of social influence within the team. The mediation model was non-significant, and contrary to existing literature, social interaction and work interdependence were not significantly related to any of the other variables in the model.Demographic homogeneity was related to both perceptions of social influence and to within-group agreement on perceptions of the work environment in the opposite direction from that hypothesized. Post-hoc analyses suggest that organizational cultural orientation (collectivist or individualist) may moderate the relationship between demographic homogeneity and within-group agreement on perceptions of the work environment.

Esta tesis pretende aportar soluciones a los problemas de gestión de los recursos lingüísticos (RRLL) dentro de una organización dedicada a la producción de documentación técnica multilingüe (DTM). El problema general de la DTM está vinculada a la infrautilización de los recursos lingüísticos de mayor valor, esto es: diccionarios terminológicos y memorias de traducción. El objetivo de este análisis es diseñar e implementar un sistema de gestión de RRLL y de conocimiento que optimice la gestión de los proyectos de traducción dentro de una empresa dedicada a la producción de DTM, en concreto STAR Servicios Lingüísticos, SL. Para analizar el proceso de gestión y poder dar propuestas de solución se ha adoptado una propuesta metodológica utilizada en la gestión empresarial conocida como auditoría de la información cuyas fases son las siguientes: 1. Implicación en implantar una política de la información por parte de la dirección de la entidad 2. Identificación de necesidades y evaluación de la viabilidad del proyecto 3. Planificación de la auditoría de la información 4. Análisis e interpretación de los datos:·recogida de datos inventario, encuestas, diagramas de flujo ·catálogo de problemas ·catálogo de propuestas 5. Implementación de las propuestasLa aplicación de la auditoría de la información confiere especial relevancia a los RRLL y a sus informaciones asociadas. Desde la perspectiva empresarial los RRLL se entienden como activos lingüísticos y desde la perspectiva profesional de los traductores y gestores se entienden como bases de conocimiento. Tras el análisis e interpretación de los datos se propone una sistematización de la descripción semántica y estructuración lógica de los RRLL para optimizar la recuperación de la información. De la implementación de las propuestas se desarrolla COGNImática, una herramienta que soluciona la infrautilización de los RRLL y que se ha definido como un sistema de tres módulos relacionados entre sí: gestor documental de diccionarios, gestor de proyectos y gestor de corpus paralelos. COGNImática se basa en técnicas de técnicas de documentación recuperación y extracción de la información, y es una herramienta colaborativa. Y esto es así porque es un instrumento para la mejora de la política de la (in)formación empresarial por contribuir a un cambio abocado a compartir, consultar, sumar, unificar, proponer y construir, es decir, una mejora de la gestión del conocimiento y con ello una mejora de las condiciones laborales para los integrantes de la empresa analizada.

求職者與企業雙方都冀望尋求彼此契合的對象，新進人員藉以認同組織、發揮所長；企業藉以提升新人對組織的承諾感，進而獲得其良好績效。論及契合多以價值觀為核心，又由於直屬主管與部門同事是影響新人的關鍵角色，因此將其視為契合比較之重要對象，分別探討新進人員與直屬主管及與資深同事的價值觀契合度對新人組織承諾的影響。然而，新人與主管及同事的互動關係也影響了新人對組織的態度，故在價值觀契合度影響組織承諾的關係中，新進人員與主管的交換關係(LMX)以及新進人員與資深同事的交換關係(TMX)應存在著干擾作用。 因此，本研究分別以新進人員□直屬主管及新進人員□部門資深同事價值觀（四構面）契合度為自變數，新人組織承諾（三構面）為依變數，LMX和TMX為干擾變數，針對國內一製造業之新進人員、直屬主管、部門資深同事以問卷方式蒐集資料，總計發放635份卷，回收257份；經客觀配對成功之最後分析樣本：新進人員38人，直屬主管20人及部門資深同事93人。資料分析方法採敘述性統計分析、相關分析描述變項的特徵及變項間的關係，並以階層迴歸分析檢驗變項間的影響和干擾效果。研究假設檢驗結果如下： 1.新進人員□直屬主管之自我增進價值觀契合度對「努力承諾」和「價值承諾」有顯著的正向影響 2.新進人員□部門資深同事之自我增進價值觀契合度對「努力承諾」和「價值承諾」有顯著的正向影響 3. TMX在「新人□同事價值觀契合度對新人努力承諾關係」及「新人□同事價值觀契合度對新人價值承諾關係」中有顯著的干擾效果 研究結果顯示，直屬主管與資深同事皆是影響新人對公司態度的重要接觸群體。在涵蓋一般價值觀的四構面價值觀中，新人與直屬主管、資深同事「自我增進」價值觀契合度是影響新人組織承諾的重要因素，談及契合與否應重視與工作成效相關的「自我增進價值觀」。又基於高TMX在價值觀契合對組織承諾關係的干擾效果，在契合度低的情況下，員工與同事有好的交換關係品質時能夠使低組織承諾的情況不致產生。因而本研究欲提升員工組織承諾，可將發展重點放在建立與同事的關係上，以代替招募價值觀契合者，或企圖改變員工價值觀使與組織契合所做的努力。
