Nowadays, the cultivation of cane is the third most important in the country, mainly for representing an alternative and renewable source of energy. Environment and social equity concern have gotten stronger in the last years, especially due to market globalization. As a consequence of society s awareness, roused by this new attitude in the world, comes the need to adapt agriculture and agro industrial activities in order for all production systems to generate positive impacts to the environment and society. Therefore, sustainability has become the number one competition factor to the agricultural chains. A methodology entitled Sustain Sugar Method was developed in this research for the evaluation of sustainability in environmental, economical and social dimensions of the sugar cane production in the state of São Paulo. This methodology was made with adequate sustainability indicators to the case. A conceptual model of this system was developed in the state of São Paulo; it follows criteria and has attributes which represent the complexity of the theme sustainability. It can also effectively guide the gathering and validation of the sustainability indicators and its thresholds so that it is an effective tool to the responsible decisive organs and formulators of public policies. The methodology used for the model formulation as well as for the construction of the methodological proposal was: i) gathering of available information about sustainable sugar cane production; ii) formulation of indicators from specialized literature; e iii) the proposed indicators were systemized and organized in the Sustain Sugar Database and later validated by consulting specialists of the academic and production fields, plants and producers through remote consults (Applying the Delphi consult Technique to the specialists) and through a workshop. With this model and the method, the objective is to outline the sustainable sugar cane productive system in the state of São Paulo. / A cana-de-açúcar representa umas das mais antigas culturas do Brasil. Atualmente, o cultivo de cana é o terceiro mais importante em superfície ocupada no País, principalmente por representar uma fonte alternativa e renovável de energia. A preocupação com o ambiente e com a equidade social se fortaleceu nos últimos anos, especialmente devido à globalização dos mercados pois, com esta, vieram maiores cobranças sobre a produção dos produtos comercializados. Em consequência da conscientização da sociedade, despertada por essa nova postura mundial, surge a necessidade da adequação de atividades agrícolas ou agroindustriais, para que todo o sistema de produção gere impactos positivos para o ambiente e para a sociedade. Desse modo, a sustentabilidade atualmente figura como item fundamental para conferir competitividade às cadeias agrícolas. Neste trabalho foi desenvolvida uma metodologia, intitulada Método Sustenta-Cana , para a avaliação da sustentabilidade nas dimensões ambiental, agrícola/industrial, social, produtos/subprodutos, tecnológica e política do sistema de produção de cana-de-açúcar no estado de São Paulo. Para o desenvolvimento desta metodologia com indicadores de sustentabilidade adequados para o caso em questão foi desenvolvido um modelo conceitual desse sistema para o estado de São Paulo, com critérios e atributos norteadores que representem a complexidade do tema sustentabilidade e que orientem de modo eficaz o levantamento e a validação dos indicadores e seus limiares de sustentabilidade, de modo a possibilitar que esta seja uma ferramenta eficaz para os órgãos decisores e formuladores de políticas públicas. A metodologia consistiu, primeiramente, em: i) levantamento das informações disponíveis sobre sustentabilidade do sistema de produção da cana-de-açúcar; ii) formulação de indicadores a partir de literatura especializada; e iii) os indicadores propostos foram sistematizados e organizados no Banco de Dados Sustenta-Cana e posteriormente validados por consulta a especialistas dos setores acadêmico e produtivo, contemplando usinas e produtores, em rodadas remotas (aplicando-se a Técnica Delphi de consulta aos especialistas), e presencialmente, por meio de workshop. Com o modelo e o método desenvolvidos, espera-se fornecer subsídios para criar um retrato da sustentabilidade do sistema produtivo cana-de-açúcar no estado de São Paulo.

As tecnologias verdes assumiram uma posição importante para o desenvolvimento da sustentabilidade global, e a transferência de tecnologias pode ser um mecanismo pelo qual as indústrias podem conquistar e manter sua competitividade no mercado e garantir a sustentabilidade, promovendo uma atitude de mudança e de acompanhamento das necessidades humanas, econômicas, sociais e ambientais da era atual. O objetivo geral da tese consistiu em desenvolver um modelo conceitual de processo de transferência de tecnologia verde para os Institutos de Ciência e Tecnologia brasileiros, tendo o NIT como o agente facilitador para a cooperação. Com a revisão sistemática da literatura realizada sobre os processos e modelos de transferência de tecnologia, foi possível verificar que ainda não existem modelos aplicados para tecnologias verdes. Através da ferramenta proposta para avaliar a estrutura de transferência de tecnologia, identificou-se quais as dimensões que integram o modelo e sua relação com os grupos de pesquisa e NITs. O modelo proposto elaborado consistiu em três macrofases: pré-transferência, desenvolvimento e pós-transferência. Através deste modelo é possível apontar, antecipadamente, as principais barreiras que impedem esse processo, além de fomentar desenvolvimentos científicos e tecnológicos futuros, capazes de influenciar de forma significativa nas indústrias, uma vez que anteciparia futuros problemas relativos à propriedade intelectual que possam inviabilizar a cooperação entre universidade-indústria no Brasil. / Green technologies have assumed an important role towards global sustainability development. Technology transfer processes could become the responsible mechanism for industries to assure and keep market competitiveness and sustainability, promoting a change of attitude and monitoring nowadays economical, social and human needs. The main purpose of this study was to develop a conceptual model of green technology transfer process for Brazilian Science and Technology Institutes, focusing on the Technology Transfer Offices (TTO) as the facilitators of such cooperation. Literature review on processes and methodology for technology transfer showed that there is no specific methods for green technologies. Through the proposed tool designed to evaluate technology transfer processes, it was possible to identify the dimensions integrated into the model and into the research group and TTOs. The elaborated model consists of three distinct phases: before, during and after technology transfer process. Such tool besides being able to point out, beforehand, the barriers which interfere negatively on such process, it is able to promote future scientific and technological development capable of significantly influence on industries specially because it can anticipate intellectual property issues that could undermine industry-university cooperation in Brazil.

Os investimentos no setor de água potável no Brasil, apesar de significativos, ainda não apresentam os resultados esperados na melhoria da saúde e da qualidade de vida da população, especialmente nas pequenas comunidades do país. A aplicação de recursos continuará limitada enquanto não forem fortalecidos os aspectos técnicos, econômicos, institucionais, ambientais, sociais e culturais que permitam a seleção de obras sanitárias eficientes e sustentáveis. Neste contexto, foi desenvolvido um modelo conceitual de seleção de tecnologias de tratamento de água constituído por 17 sub-níveis que progressivamente \"filtram\" as opções tecnológicas aplicáveis em comunidades brasileiras inferiores a 20.000 habitantes. Os aspectos envolvidos no modelo se relacionam: i) ao risco presente na fonte de abastecimento superficial; ii) à eficiência das tecnologias para eliminar ou reduzir o risco a valores de acordo à Portaria no 518 (2004); iii) ao tratamento, aproveitamento e disposição dos resíduos gerados e iv) aos custos dos sistemas com vazões de projeto de 10 a 40 L/s. As principais conclusões da pesquisa foram: i) a aplicabilidade do modelo está restrita à estações de tratamento de água - ETAs que cumprem todos seus requisitos de domínio, ii) os valores-limite das variáveis de risco podem conduzir o engenheiro a uma seleção preliminar das possíveis alternativas de tratamento; entretanto, somente a partir de estudos de tratabilidade da água e de testes em instalação piloto será possível definir a ETA mais conveniente, iii) as seleções das tecnologias para tratamento, aproveitamento e disposição do resíduo não devem ser avaliadas de forma independente às empregadas nas ETA; iv) Os custos calculados pelo modelo dificilmente podem ser comparados com sistemas já existentes; v) os resultados do modelo variam em função dos dados de entrada; assim, o usuário deve ter consciência da qualidade da informação fornecida para obter resultados satisfatórios. / Despite being significant the investments in the brazilian drinking water sector still have not presented the expected results regarding the improvement of both health and population\'s life quality, especially in the small communities of the country. The application of resources will continue limited while the technical, economical, institutional, environmental, social and cultural aspects that allow for the selection of efficient and maintainable sanitary works are not strengthened. In this context, a conceptual model to select technologies for water treatment has been developed. It consists of 17 sub-levels that progressively \"filter\" the applicable technological options in brazilian communities of under 20.000 inhabitants. The aspects involved are related to: i) the risk present in the source of superficial supply; ii) the efficiency of the technologies to lither eliminate or reduce the risk to the values according law no 518 (2004); iii) the treatment, use and disposition of the generated residues and iv) the costs of the systems with project flows from 10 L/s to 40L/s. The main conclusions of the research were: i) the applicability of the model is restricted to water treatment plants - WTPs that accomplish all their domain requirements, ii) the limit values of the risk variables can lead the engineer to a preliminary selection of the possible treatment alternatives; however, only from studies of water treatment and tests in pilot installations it will be possible to define the most convenient WTP, iii) the selections of the technologies for treatment, use and disposition of residues should not be appraised in an independent way of the ones employed in WTPs, iv) the costs calculated by the model can hardly be compared with systems already existent; v) the results of the model vary in function of the input data; therefore, the user should be aware of the quality of the information supplied to obtain satisfactory results.

As more organisations apply project management to perform projects in order to deliver high quality products and services, the demand for project managers grows, and thus more research is required on the effectiveness of project managers (Crawford, 2005). Hence, this research project aims to provide an in-depth understanding of the effectiveness of project managers within project-oriented organisations.The purpose of this research project is to fill the research gap by bringing the practical perspective of the effectiveness of project managers, from different informants in various fields, into the theoretical perspective in the form of a conceptual model (i.e. the combination of the constructs: core categories, categories, and concepts) through in-depth interviews and the grounded theory method. This qualitative study attempts to provide a fresh insight into the leading and managing projects, and hence into the effectiveness of project managers in project-oriented organisations.This research project is one of the very rare studies investigating the matter of an effective project manager, particularly within project-oriented organisations. It is also one of the very few studies investigating the role of leadership in the effectiveness of project managers, particularly within project-oriented organisations. In addition, it is one of the very rare studies providing the conceptual model as the criteria for project managers to become effective within project-oriented organisations. Furthermore, it is one of the very rare studies providing the practical model as the tool to evaluate the effectiveness of project managers within project-oriented organisations. The research project provides an insightful understanding of the notion of leadership, management, and emotional intelligence, and uncovers their roles in the effectiveness of project managers within project-oriented organisations.The research project highlights the value of qualitative inquiry for exploring individuals’ perceptions and lived experiences, as well as investigating phenomena which have been relatively under-investigated to date. It also highlights the usefulness of grounded theory, which builds concepts grounded in empirical data.

Dès le début du 20ème siècle, les eaux souterraines de l’aquifère transfrontalier Milk River (MRA) ont constitué une importante ressource dans le sud de l’Alberta (Canada) et le nord du Montana (USA). L’utilisation intensive de cette ressource sous un climat semi-aride a provoqué une baisse importante des niveaux d’eau localement, si bien que des inquiétudes concernant la pérennité du MRA sont apparues dès les années 60. Les études précédentes du MRA étaient limitées par les frontières nationales, empêchant ainsi une compréhension complète de la dynamique de l’aquifère. L’objectif de cette thèse était de réaliser une étude transfrontalière du MRA afin de caractériser cette ressource régionale d’eau souterraine selon ses limites naturelles. À cette fin, trois modèles transfrontaliers ont été réalisés: un modèle géologique, un modèle conceptuel hydrogéologique et un modèle numérique d’écoulement souterrain. Des travaux de terrain de part et d’autre de la frontière Canada/USA et une revue de littérature exhaustive des études précédentes ont supporté la réalisation de ces modèles. De plus, une première évaluation des niveaux d’exploitation historiques du MRA a été réalisée en Alberta.Le modèle géologique 3D (50 000 km2) représente le MRA (Membre Virgelle de la Formation Milk River/Eagle) et ses unités confinantes continûment à travers la frontière internationale. Le développement de ce modèle a requis une harmonisation des nombreuses nomenclatures stratigraphiques de la région et la délimitation transfrontalière du MRA.Le modèle conceptuel hydrogéologique du MRA a montré deux flux d’écoulement souterrains transfrontaliers, dirigés du Montana vers l’Alberta. La Milk River intercepte la majeure partie du flux souterrain venant du sud, si bien que l’écoulement au nord de la rivière est très faible. Les analyses isotopiques confirment que les eaux du MRA sont principalement fossiles à l’exception de la zone de recharge située le long de la zone d’affleurement du MRA. Les zones du MRA avec une forte conductivité hydraulique et de faibles concentrations en chlorures correspondent à des voies d’écoulement préférentielles. L’émergence des eaux du MRA a lieu via la drainance à travers les unités confinantes notamment le long des vallées enfouies.Le modèle numérique (26 000 km2) d’écoulement souterrain du MRA en régime permanent est une transposition des modèles géologique et conceptuel. Il montre que le modèle conceptuel précédemment développé est hydrauliquement plausible. Le modèle d’écoulement donne une meilleure compréhension du système aquifère en représentant la dynamique de l’écoulement souterrain dans la situation pré-exploitation. Le traçage de particules indique des temps de résidence advectifs de près de 750 000 ans à la limite nord du MRA, ce qui est inférieur aux âges obtenus par les analyses isotopiques (2 Ma).Les bilans en eau des modèles conceptuels et numériques montrent tous les deux que l'extraction de l'eau souterraine dépasse de loin la recharge au nord de la Milk River.Un modèle d'écoulement transitoire serait requis pour définir le volume d'eau provenant de l'emmagasinement dans le MRA et préciser le rôle des aquitards durant le pompage. Par ailleurs, en tant que ressource internationale partagée, une gestion transfrontalière des eaux du MRA serait justifiée dans la région comprise entre la zone de recharge au Montana et le sud de la Milk River en Alberta. Ainsi, ces trois modèles transfrontaliers du MRA forment une base commune internationale de connaissances scientifiques à l'échelle de l'aquifère et pourraient supporter l'évaluation future du meilleur usage possible de cette ressource partagée et limitée. De futurs travaux peuvent inclure l'effet des champs de gaz localisés aux limites du MRA et les conditions paléo-hydrogéologiques liées à l'évolution géochimiqie de l'au souterraine. / Since the beginning of the 20th century, groundwater from the Milk River Aquifer (MRA) has been an important water resource in southern Alberta (Canada) and northern Montana (USA). The intensive use of this resource under a semi-arid climate has locally led to important drops in waters levels, thus raising concerns on the MRA sustainability since the 1960’s. Previous MRA studies were limited by the national boundaries, thus preventing a full understanding of the aquifer dynamics. The objective of this thesis was to carry out a transboundary study of the MRA to define this regional groundwater resource within its natural boundaries. For this purpose, three cross-border models were developed: a geological model, a conceptual hydrogeological model and a numerical groundwater flow model. These developments were supported by focused field work on both sides of the Canada/USA border and a comprehensive review of previous studies. Furthermore, a first assessment of the historical exploitation levels of the MRA was done for southern Alberta.The 3D geological model (50,000 km2) continuously represents the MRA (Virgelle Member of the Milk River/Eagle Formation) and confining units through the international border. Development of this model required harmonization of various stratigraphic nomenclatures in the study area and the transboundary delineation of the MRA extent.The hydrogeological conceptual model of the MRA indicated two transboundary groundwater fluxes from Montana to Alberta. The Milk River intercepts most of the groundwater flux incoming from the south, thus leading to limited groundwater flow north of the Milk River. Isotopic analyses confirm that the MRA contains mostly fossil groundwater, with the exception of the recharge area located along the outcrop area of the aquifer. Areas within the MRA with a high hydraulic conductivity and low chloride concentrations correspond to preferential groundwater flowpaths. Discharge from the aquifer occurs as vertical leakage through the overlying confining units, especially along bedrock valleys.The numerical steady-state groundwater flow model of the aquifer system (26,000 km2) is a transposition of the geological and conceptual models, and it shows that the previously developed conceptual model is hydraulically plausible. The groundwater flow model provides a better understanding of the aquifer system by representing the dynamics of groundwater flow under pre-development conditions. Particle tracking indicates advective residence times of up to 750,000 years in the northern limit of the aquifer, which is lower than ages obtained from isotopic analyses (2 Ma).The area south of the Milk River benefits from all of the transboundary groundwater flux from Montana whereas north of the Milk River, only a portion of the recharge flux coming from the south is transmitted due to the interception of the Milk River.Groundwater budgets from both the conceptual and numerical models show that groundwater extraction far exceeds recharge north of the Milk River. A transient model would be required to determine how much water is derived from storage in the MRA and to assess the role of the confining units during pumping. Furthermore, as an internationally shared resource, a transboundary management of the MRA would be appropriate, especially in the area comprised between the recharge area in Montana and the Canadian reach of the Milk River.Together, these transboundary models of the MRA constitute a common international basis of scientific knowledge at the aquifer scale and could support further assessments of the best possible exploitation of the shared but limited resource.Future works could include the study of the effects of the gas fields located at the limits of the MRA as well as paleo-hydrogeological conditions relative to the geochemical evolution of groundwater.

Indiana University-Purdue University Indianapolis (IUPUI) / The purpose of this study is to advance theoretical understanding of how an adolescent with incurable cancer prepares for end-of-life (EOL). A theoretical model was developed to link awareness, acceptance, and willingness to take action to EOL preparedness (knowledge about EOL, acknowledgement of grief and emotion, identification of the meaning of death and spirituality, and conceptualization of personal plan) and communication about EOL preferences and priorities; and to determine impact on quality of life (QOL). Method: Case study research method was used to guide data collection and analyses on two adolescent cases across two time points. The theoretically-based model was developed prior to data collection and based on research studies conducted in adult and pediatric EOL literature. Multiple sources of data were collected and triangulated to assess relationships between qualitative and quantitative data. Through an iterative process of pattern matching, data were compared to constructs in the conceptual model for both across cases, and across time. Results: Results indicate awareness (cognitive recognition of incurable prognosis) and acceptance (emotional acknowledgement of incurable prognosis) are both fluid concepts and varied within each time point and across time. Contextual factors (demographic, environmental, personal, and social support characteristics) influenced awareness, EOL preparedness, and willingness to take action; and directly influenced QOL. Level of awareness influenced involvement in EOL preparedness. Information preference and willingness to engage in discussions regarding knowledge about EOL were incongruent with actual knowledge about EOL. Adolescents demonstrated a willingness to discuss potential disease progression in order to conceptualize an EOL advanced care plan regardless of emotional acceptance of incurable prognosis. In contrast, acknowledgment of grief and emotions, and identification of the meaning of death and spirituality were related to acceptance of incurable prognosis and further determined conceptualization of immediate EOL priorities. Social constraint or lack of ability to discuss prognosis, was identified as an important construct that influenced communications. Implications: This study provides increased theoretical understanding of how adolescents living with advanced cancer confront EOL. Insight led to theory modification and expansion which may serve as a guide for future research to assist clinicians caring for adolescents living with incurable cancer. Victoria L.

A geochemical study of major springs and wells in Spring Valley, Nevada, and Snake Valley, Utah-Nevada was initiated in response to the Clark, Lincoln and White Pine Counties Groundwater Development Project proposed by the South Nevada Water Authority (SNWA). Water budget estimates suggest that interbasin flow accounts for a significant portion (~25%) of the water budgets in Spring and Snake Valleys. Although interbasin flow is possible in some areas, alternative plausible explanations place significant uncertainty on water budget allocations. To examine the plausibility of local and interbasin flow paths the groundwater flow in Spring and Snake Valleys was evaluated using solute and isotopic data. Evidence for local flow paths includes: 1) stable isotope values in local areas which are similar to isotope values in adjacent recharge zones; 2) measurable 3H content and 14C activities ≥ 50 pmc in most samples which suggests short residence times; and 3) plausible geochemical models of local flow paths. Previously defined interbasin flow paths in southern Spring Valley are marked by samples that have low 14C activities (mean = 20.14 pmc), which are consistent with long residence times and can be explained by either interbasin flow from adjacent basins or deep circulation in the basin-fill sediments of Spring Valley. Interbasin flow from southern Spring Valley to southern Snake Valley cannot be confirmed or rejected based on the current data and modeling constraints, which result in plausible models involving both local flow paths and interbasin flow paths. Interbasin flow from northern Spring Valley to northern Snake Valley is unlikely and can be explained by the deep circulation of groundwater that is mixed with modern recharge. The plausibility of alternative explanations to describe previously defined interbasin flow paths suggests that water budget allocations in Spring and Snake Valleys should be redistributed or reevaluated. The use of existing water budgets that allocate large components of water to interbasin flow to determine the distribution of water resources may result in incorrect estimations of available resources.
