Soil quality response to land-use change for sugarcane expansion in Brazil

Globally, increasing demands for biofuels have intensified the rate of land-use change (LUC) for expansion of bioenergy crops. In Brazil, the world\'s largest sugarcane-ethanol producer, sugarcane area has expanded by 35% (3.2 Mha) in the last decade. Sugarcane expansion has resulted in extensive pastures being subjected to intensive mechanization and large inputs of agrochemicals, which have direct implications on soil quality (SQ). We hypothesized that LUC to support sugarcane expansion leads to overall SQ degradation. To test this hypothesis we conducted a field-study at three sites in the central-southern region, to assess the SQ response to the primary LUC sequence (i.e., native vegetation to pasture to sugarcane) associated to sugarcane expansion in Brazil. At each land use site undisturbed and disturbed soil samples were collected from the 0-10, 10-20 and 20-30 cm depths. Soil chemical and physical attributes were measured through on-farm and laboratory analyses. A dataset of soil biological attributes was also included in this study. Initially, the LUC effects on each individual soil indicator were quantified. Afterward, the LUC effects on overall SQ were assessed using the Soil Management Assessment Framework (SMAF). Furthermore, six SQ indexes (SQI) were developed using approaches with increasing complexity. Our results showed that long-term conversion from native vegetation to extensive pasture led to soil acidification, significant depletion of soil organic carbon (SOC) and macronutrients [especially phosphorus (P)] and severe soil compaction, which creates an unbalanced ratio between water- and air-filled pore space within the soil and increases mechanical resistance to root growth. Conversion from pasture to sugarcane improved soil chemical quality by correcting for acidity and increasing macronutrient levels. Despite those improvements, most of the P added by fertilizer accumulated in less plant-available P forms, confirming the key role of organic P has in providing available P to plants in Brazilian soils. Long-term sugarcane production subsequently led to further SOC depletions. Sugarcane production had slight negative impacts on soil physical attributes compared to pasture land. Although tillage performed for sugarcane planting and replanting alleviates soil compaction, our data suggested that the effects are short-term with persistent, reoccurring soil consolidation that increases erosion risk over time. These soil physical changes, induced by LUC, were detected by quantitative soil physical properties as well as by visual evaluation of soil structure (VESS), an on-farm and user-friendly method for evaluating SQ. The SMAF efficiently detected overall SQ response to LUC and it could be reliably used under Brazilian soil conditions. Furthermore, since all of the SQI values developed in this study were able to rank SQ among land uses. We recommend that simpler and more cost-effective SQI strategies using a small number of carefully chosen soil indicators, such as: pH, P, K, VESS and SOC, and proportional weighting within of each soil sectors (chemical, physical and biological) be used as a protocol for SQ assessments in Brazilian sugarcane areas. The SMAF and SQI scores suggested that long-term conversion from native vegetation to extensive pasture depleted overall SQ, driven by decreases in chemical, physical and biological indicators. In contrast, conversion from pasture to sugarcane had no negative impacts on overall SQ, mainly because chemical improvements offset negative impacts on biological and physical indicators. Therefore, our findings can be used as scientific base by farmers, extension agents and public policy makers to adopt and develop management strategies that sustain and/or improving SQ and the sustainability of sugarcane production in Brazil.

O papel da inteligência emocional na gestão de conflitos e o sucesso escolar

As escolas têm como objetivo primário preparar os jovens para a integração na sociedade. Como tal, estimulam o desenvolvimento de competências para tornar os alunos aptos para as adversidades do futuro. Tradicionalmente, admite-se que as capacidades cognitivas têm um grande peso no sucesso escolar. Contudo, as competências socio afetivas têm sido sugeridas como variáveis potencialmente explicativas do desempenho escolar. O presente estudo pretendeu verificar a associação entre a Inteligência Emocional (IE) na Gestão de Conflitos e no sucesso escolar de alunos (n=52; média ± desvio-padrão: 17,7±0,7 anos) do ensino secundário dos Estabelecimentos Militares de Ensino - não superior (EME’s). A metodologia de investigação apresentou duas fases: 1) pesquisa bibliográfica sobre a IE, gestão de conflitos e o sucesso escolar; 2) aplicação e análise dos questionários, o MSCEIT e o autodiagnóstico dos estilos de gestão de conflitos. Observou-se que os alunos dos EME’s contêm valores de IE superiores aos valores reportados na sua faixa etária, e que utilizam maioritariamente três estilos de gestão de conflitos, nomeadamente: a competição (preferencial), inação, e (o menos utilizado) a cedência. Verificou-se que a IE não prediz a gestão de conflitos, contudo observou-se uma correlação positiva, entre o estilo cedência e a IE. Verificou-se também que a IE prediz 33% da disciplina de matemática, e é diferenciadora quanto ao género.

Burden of care and general health in families of patients with schizophrenia

Background De-institutionalization of psychiatric patients has led to a greater emphasis on family management in the community, and family members are often overwhelmed by the demands that caring for a patient with schizophrenia involves. Most studies of family burden in schizophrenia have taken place in developed countries. The current study examined family burden and its correlates in a regional area of a medium income country in South America. Method Sixty-five relatives of patients with schizophrenia who were attending a public mental health out-patient service in the province of Arica, Chile, were assessed on Spanish versions of the Zarit Caregiver Burden Scale and SF-36 Health Survey (SF-36). Results Average levels of burden were very high, particularly for mothers, carers with less education, carers of younger patients and carers of patients with more hospitalisations in the previous 3 years. Kinship and number of recent hospitalisations retained unique predictive variance in a multiple regression. Burden was the strongest predictor of SF-36 subscales, and the prediction from burden remained significant after entry of other potential predictors. Conclusions In common with families in developed countries, family members of schizophrenia patients in regional Chile reported high levels of burden and related functional and health impact. The study highlighted the support needs of carers in contexts with high rates of poverty and limited health and community resources.

On measuring wealth: A case study on the state of Queensland

In order for policy makers to plan effectively for sustainable development, there is a need for measures of welfare that consider changes in the natural capital stock. Current measures based on conventional national accounting are flawed because they are based solely on flow measures and do not account for environmental effects. In this paper, we use an expanded measure of wealth to estimate the value of natural capital for Queensland. The state's stock of natural capital is valued at A$355.6 billion, of which non-timber forest resources account for 45.3%, ecosystem services 20.0%, and mineral resources 17.6%. This figure is a conservative estimate of the true value since some significant components such as the ecological and life-support functions of the environment are excluded. The estimates highlight the relative importance of different forms of natural capital and can be used to draw the attention of policymakers to the need to give adequate weight to the value of such services in decision-making processes.

RELAÇÃO ENTRE ESTILO DE LIDERANÇA E COMPROMETIMENTO ORGANIZACIONAL AFETIVO

A organização necessita de um capital humano efetivamente disposto a contribuir com as suas estratégias e metas. Vários estudos já comprovaram que o comprometimento das pessoas influencia nos resultados. O que mais tem relação com o desempenho é o comprometimento afetivo. As lideranças, através dos seus estilos, podem também contribuir para gerar um desempenho e resultados melhores para as organizações. O objetivo desta pesquisa foi analisar a relação entre os estilos de liderança e o comprometimento organizacional afetivo. Utilizando o método quantitativo, instrumento para coleta de dados foi construído um questionário de autopreenchimento composto por três escalas que medem as variáveis da pesquisa. Os dados, todos de natureza numérica, formaram um banco eletrônico que foi analisado por meio de estatística descritiva e multivariadas do teste de correlação de Pearson do software SPSS, versão 19.0. A pesquisa foi realizada com 92 trabalhadores de uma empresa privada na cidade de São Paulo, utilizando a escala de Siqueira (2008) para medir o comprometimento organizacional afetivo dos trabalhadores e a escala de avaliação do estilo gerencial de Melo (2004) para identificar o perfil dos líderes destes trabalhadores na visão dos mesmos, porem com variações em função do tamanho da amostra, reveladas pelo valor do t de Student nos teste de Bootstrap. Foram analisadas as correlações entre os três estilos de liderança tarefa, relacionamento e situacional com o comprometimento organizacional afetivo. As análises revelaram fracas correlações entre os estilos de liderança e o comprometimento organizacional afetivo, sendo significativas (com erro inferior a 5%) as correlações do comprometimento com o estilo tarefa e com o estilo situacional, porém com variações em função do tamanho da amostra. Estes resultados contribuem para o aprimoramento dos processos de gestão de pessoas, sendo úteis para as áreas de Recursos Humanos de maneira geral, a fim de promover melhorias no desenvolvimento das lideranças e no comprometimento das pessoas através das políticas da organização.

Transfer of technology to China:A Scandinavian and European perspective

This paper examines the question of technology transfer from the perspective of techno-economic security and how companies respond to the possibility of losing competitive advantage through misappropriation or leakage. It explores transfers from Europe to China and addresses in particular the operations of Scandinavian companies within the context of the general picture for other European firms. Its point of departure is the authors' earlier research that looked at the motivations for transfer and the awareness of companies of techno-economic security issues. This has been supplemented by new data gathered by the authors from a number of Scandinavian companies in China. Specific actions have been identified and the ownership issue is introduced together with consideration of the role of the companies against the 'Ferdows' model. The analysis shows that the nature of the security question has changed together with the evolving context in which the companies are operating. In turn, the response of companies is contingent on a number of factors including the time horizon of the strategy for a unit in China and the nature of the strategy. It is also influenced by the form of ownership and management style in a particular organisation. © 2002 Elsevier Science Ltd. All rights reserved.

Quality risk in global supply network

Purpose - The rise of recent product recalls reveals that manufacturing firms are particularly vulnerable to product quality and safety where goods and materials have been sourced globally. The purpose of this paper is to explore the issues of quality and safety problems in global supply networks, and introduce a supply chain risk management (SCRM) framework to reduce the quality risk. Design/methodology/approach - A conceptual SCRM framework for mitigating quality risk is developed. In addition, four SCRM treatment practices are proposed by consolidating the empirical literature in the operations management and supply chain management areas. The general feasibility was discussed based on literature. Findings - The research has identified the root causes of the recent product recalls and a series of product harm scandals ranging from automobiles to unsafe toys. Supply chains are extended by outsourcing and stretched by globalization, which greatly increase the complexity of supply networks and decrease the visibility in risk and operation processes. Originality/value - The paper identifies four SCRM practices, and proposes two distinct antecedents that can prompt the effectiveness of SCRM. © 2011 Emerald Group Publishing Limited.

Developing The Ladder To Professionalism

Developing The Ladder To Professionalism by Tom Baum, Manager, Curricula Development Unit and Patricia Reid, Training Advisor, Curricula Development Unit at the Council for Education, Recruitment and Training, State Agency for Hotels, Catering and Tourism in Dublin, Ireland: “Developments are currently in hand to promote increased professionalism in management within the hotel and catering industry in Ireland. The authors discuss the particular responsibility of educational agencies. Recent initiatives to provide a comprehensive and flexible career ladder encompassing craft training, in-service and “second-chance” education, as well as more conventional college-based initial management are reviewed, as are attempts by various industry associations to enhance the professionalism of members.” In this discussion, the authors have primarily devoted their attention to degree gaps in professionalism in the hospitality industry, and the measures that can be taken to mitigate these circumstances. “The hotel, catering, and tourism industry, in common with others involved in the service function, has been relatively slow to adopt modern approaches to management and technology at all levels,” Baum and Reid want you to know. The authors hail from Ireland and point to steps that the industry, in Ireland, is taking to address service problems. “Developments are taking place in Ireland toward professionalism in management in the context of the Irish hotel and catering industry; education and educationally related institutions have taken a role in contributing to the professionalization of work in this area,” say the authors. Baum and Reid point to CERT’s - The State Training Agency for Hotels, Catering and Tourism - involvement in promoting professionalism in the Irish hospitality industry, and provide a comprehensive graph to illustrate CERT’s paths to successful management. Worthy of note is, proprietor management is more common on that side of the Atlantic’, with most properties tending to be smaller than U.S. chain operations. That fact, by no means suggests that management style is indeed complete in the U.K, but it can be said that maybe such style is more congenial. “However, finding the balance between operationalism and the management and development functions seems to underpin perhaps the cardinal problems of professionalism in hotel and catering management in Ireland,” say the authors. “The dichotomy, clearly represented in the management of the industry, is equally evident within the educational and training system and also in the limited influence of associations…” Baum and Reid expand on that issue. The authors do concede that it is difficult to quantify what exactly constitutes good professionalism in the hospitality industry; it is, after all, a fairly subjective concept. They continue by describing some of the degree and sub-degree programs being offered in Ireland.

Remédiation cognitive portant sur les aspects fluide et cristallisé de l’intelligence auprès d'adolescents présentant un fonctionnement intellectuel limite : approche par le jeu.

L’objectif principal de cette thèse était de créer, d’implanter et d’évaluer l’efficacité d’un programme de remédiation cognitive, intervenant de façon comparable sur les aspects fluide (Gf) et cristallisé (Gc) de l’intelligence, au sein d’une population d’intérêt clinique, les adolescents présentant un fonctionnement intellectuel limite (FIL). Compte tenu de la forte prévalence de ce trouble, le programme de remédiation GAME (Gains et Apprentissages Multiples pour Enfant) s’est développé autour de jeux disponibles dans le commerce afin de faciliter l’accès et l’implantation de ce programme dans divers milieux. Le premier article de cette thèse, réalisé sous forme de revue systématique de la littérature, avait pour objectif de faire le point sur les études publiées utilisant le jeu comme outil de remédiation cognitive dans la population pédiatrique. L’efficacité, ainsi que la qualité du paradigme utilisé ont été évaluées, et des recommandations sur les aspects méthodologiques à respecter lors de ce type d’étude ont été proposées. Cet article a permis une meilleure compréhension des écueils à éviter et des points forts méthodologiques à intégrer lors de la création du programme de remédiation GAME. Certaines mises en garde méthodologiques relevées dans cet article ont permis d’améliorer la qualité du programme de remédiation cognitive développé dans ce projet de thèse. Compte tenu du peu d’études présentes dans la littérature scientifique concernant la population présentant un FIL (70

Understandings of transnational families in debates on Migration and development

International migration sets in motion a range of significant transnational processes that connect countries and people. How migration interacts with development and how policies might promote and enhance such interactions have, since the turn of the millennium, gained attention on the international agenda. The recognition that transnational practices connect migrants and their families across sending and receiving societies forms part of this debate. The ways in which policy debate employs and understands transnational family ties nevertheless remain underexplored. This article sets out to discern the understandings of the family in two (often intermingled) debates concerned with transnational interactions: The largely state and policydriven discourse on the potential benefits of migration on economic development, and the largely academic transnational family literature focusing on issues of care and the micro-politics of gender and generation. Emphasizing the relation between diverse migration-development dynamics and specific family positions, we ask whether an analytical point of departure in respective transnational motherhood, fatherhood or childhood is linked to emphasizing certain outcomes. We conclude by sketching important strands of inclusions and exclusions of family matters in policy discourse and suggest ways to better integrate a transnational family perspective in global migration-development policy.

A representação social do papel de gestores em organizações não governamentais

The discussions concerning the absence of a management model appropriate to the peculiarities of third sector organizations have not been impeditive to their emphasized expansion in the last decades. In the attempt of understanding this phenomenon from the perspective of those who manage social organizations, this work based on the theory of social representations to understand the notion that organization managers of the third sector - based in Fortaleza CE - have of the part that they play and how this notion influences the direction of their activities. Social representations of managers of four different categories of non-governmental organizations have been investigated, each category composed of two unities. The categories researched were: social integration through art and education, prevention and treatment of alcohol and drug abuse, children s health assistance and community action. By using Doise s Societal Approach, the role of social managers translated in intraindividual, interindividual and situational processes of their actions, has been analysed within the social representations, focusing on beliefs, values, symbols and stories that give meaning to the existence of non-governmental organizations. Analysis and discussion of data displayed the existence of diversity in the understanding of managers within their practice, in other words, the management profile is also its own manager s. The branch where an organization acts is also preponderant in the shaping of a management style. It could be deduced, from to the organizations researched, that professional formation and the manager s social insertion mainly, are determinative factors in the outlining of a management model of its own. It was concluded that, due to heterogeneity of interests and action segments, there is no systematic process for social management among organizations. Management styles are supported by their director s own perception of achievement, who model organizations according to their contingencies
