Os modelos logísticos trinomiais podem ser interpretados como uma extensão natural do modelo logístico binomial para situações em que a resposta admite apenas três resultados. Introduzimos inicialmente os modelos logísticos trinomiais e discutiremos em seguida alguns aspectos inferenciais, tais como estimação e testes. Medidas de qualidade do ajuste são também apresentadas. Contudo, o principal foco deste trabalho é a apresentação de métodos de diagnóstico. Mostramos que as técnicas usuais de diagnóstico desenvolvidas para o modelo logístico binomial podem ser adaptadas para o caso trinomial. O desenvolvimento de métodos diretos para o modelo logístico trinomial é mais complexo do ponto de vista computacional, embora seja sempre possível. Discutimos alguns desses métodos, dentre os quais, o desenvolvimento de resíduos, de métodos para detectar pontos de alavanca, métodos de deleção de pontos e influência local. Comparamos os métodos adaptados com alguns métodos diretos através de exemplos. / The trinomial logistic models can be interpreted as a natural extension of the traditional binomial logistic model to situations in which the response allows only three possible results. We firts introduce the trinomial logistic modles and then some inferential aspects, such as estimation and hypothesis testing are discussed. Good-of-fit measures are also given. However, the aim of this work is the presentation of some diagnostic procedures for trinomial logistic models. We show that methods developed for binomial logistic models can adapted straightforward for trinomial models. The developement of direct methods, even though possible, in general requires more complex calculation. Some of these direct methods, suchs as evaluation of residuals, measures of high leverage points, deletion methods and local influence are apresented. Coparisons between adapted and direct methods are made via examples with real data.

This research explores one avenue for achieving sustainability within the fashion industry; which as it exists today is unsustainable. The Slow Fashion movement has an existing foundation in the larger fashion industry and is already making strides towards sustainability. The authors used this opportunity to examine a strategic approach, as its current approach is ad hoc. First, the authors assessed the Slow Fashion movement using the 5 level Framework for Strategic Sustainable Development. To analyze the Slow Fashion movement further, the concept of Leverage Points was used to provide a focused lens to assist the author’s in navigating through the fashion industry’s complex system. Findings were synthesized into thirty strategic recommendations that target various players in the Slow Fashion movement. Three key recommendations will provide the most leverage in strengthening the Slow Fashion movement: 1) Co-create Slow Fashion Principles to represent the values of the movement and a shared definition of sustainability 2) Establish an overarching global network and local chapters for the Slow Fashion movement 3) Harmonize global garment and textile labelling initiatives under a Slow Fashion label.

There is an increasing acknowledgement in Eco-municipalities – cities using the Framework for Strategic Sustainable Development (FSSD) as a tool for their planning process – of the need for Cross-Sector Collaboration, but the necessary expertise is often lacking. The purpose of this study is to better understand effective CSC in Eco-municipalities through indicating potential leverage points and inform the use of the FSSD in this specific context. An 'effective CSC' lens is constructed from general CSC literature and documents from Eco-municipalities. 187 barriers and enablers to effective cross-sector collaboration are identified from interviews with experts and interviews from the In-depth Case Study in the city of Eindhoven. An 'Importance Index' defined by alignment with Lens Factors is developed to select key indicators. These key indicators are clustered into 45 potential leverage points for effective CSC in Eco-municipalities. The use of these potential leverage points is checked in an In-depth Case Study through a Causal Loop Diagram in which nine leverage points were identified. Interrelations between these leverage points, unexpected results and methodology are discussed, conclusions are drawn, and further research is suggested.

Circular fashion has become a favoured option for the fashion industry to transition toward as the fast fashion industry becomes unsustainable. Current research within academia, business and policy focuses on the lifecycle stages of the garments, with the designer and design phase in focus. Research on circular economy predominantly looks at material flows and the lifecycle. This however fails to acknowledge potential innovation and the capacity for this change to occur. This study uncovers the perspectives of the designer, who are largely absent from the current research agenda, in order to identify leverage points in the current system which would allow accelerated transition toward a circular fashion system. Using workshops as a method to involve designers, paired together with critical systems theory; the study first highlights a large gap between academia and reality, and reveals that there is a large misconception between designers from fast fashion and designers from luxury fashion and the power influences they allow, while, underlying internal organizational structures pose as an obstacle minimizing capacities for change. Finally, using a three horizons framework as a technique, six leverage points are identified: cultural norm, strong teams, digitalization, leadership for sustainability, education & knowledge and reducing intergenerational conflicts. Overall, the study provides a holistic view of the current environment and the transition toward circular fashion, how lifecycle phases connect to circular economy frameworks and highlights innovation and the ways in which the designer can be re-empowered. The study bridges fashion business with sustainability science in a straightforward way and sets and refines the future research on solutions and challenges.

This thesis aims to understand the role of facilitated nature experiences for leadersas a step towards sustainability. Qualitative interviews were conducted with facilitators andparticipants of nature-based leadership programs (NBLP) and analyzed regarding 1) Transformative Learning Conditions, 2) Transformative Learning Outcomes, and 3) Professional Changes inspired by NBLP participation. Results show that facilitators foster Transformative Learning through six main conditions and that Transformative Learning ishappening as participants experience an increased understanding of interrelatedness within our socio-ecological system, change in worldviews, as well as realignment with purpose and gained confidence. Our findings indicate some evidence of professional changes after programcompletion that show potential to move society towards sustainability. The reconstruction of worldviews and increased human-nature connectedness depicts the potential for NBLP to address a deep leverage point that is highly effective for systemic change towards sustainability. Our research provides valuable insights for practitioners in the fields of education for sustainable development and sustainability leadership to increase both conscious and subconscious ecological systems understanding. The authors suggest NBLP should be further explored by decision-makers and researchers.

Na tentativa de contornar os problemas ainda existentes para a detecção e identificação de erros grosseiros (EGs) no processo de estimação de estado em sistemas elétricos de potência (EESEP), realiza-se, neste trabalho, uma análise da formulação dos estimadores aplicados a sistemas elétricos de potência, em especial, o de mínimos quadrados ponderados, tendo em vista evidenciar as limitações dos mesmos para o tratamento de EGs. Em razão da dificuldade de detectar EGs em medidas pontos de alavancamento, foram também analisadas as metodologias desenvolvidas para identificação de medidas pontos de alavancamento. Através da formulação do processo de EESEP como um problema de álgebra linear, demonstra-se o porquê da impossibilidade de detectar EGs em determinadas medidas redundantes, sendo proposto, na seqüência, um método para identificação de medidas pontos de alavancamento. Para reduzir os efeitos maléficos dessas medidas no processo de EESEP verifica-se a possibilidade de aplicar outras técnicas estatísticas para o processamento de EGs, bem como técnicas para obtenção de uma matriz de ponderação adequada. / To overcome the problems still existent for gross errors (GEs) detection and identification in the process of power system state estimation (PSSE), the formulations of the estimators applied to power systems are analyzed, specially, the formulation of the weighted squares estimator. These analyses were performed to show the limitations of these estimators for GEs processing. As leverage points (LP) represent a problem for GEs processing, methodologies for LP identification were also verified. By means of the linear formulation of the PSSE process, the reason for the impossibility of GEs detection in some redundant measurements is shown and a method for LP identification is proposed. To minimize the bad effects of the LP to the PSSE process, the possibility of applying other statistic techniques for GEs processing, as well as techniques to estimate an weighting matrix are also analyzed.

Human society as a whole has a reached a tipping point in its relationship with the socio-ecological systems upon which it depends. All sectors of society need to be involved in addressing this crucial challenge through a raised awareness of the issues and pro-active solutions to it. This research focuses on small urban towns and cities, where half the world’s urban population lives, and looks at the ways in which local government in these key areas can play an active role in leading sustainability through education and training. Municipalities and communities that use the framework for strategic sustainable development (FSSD) were investigated, and the conditions were identified that helped and hindered training to be really effective. Effective training, in its many forms, was found to be essential in fomenting a common language of sustainability, engaging the community, and bringing concerted strategic actions that together could foster a culture of sustainability. / <p>jpbaronb@yahoo.co.uk, rifat.pal@gmail.com, quynhvan86@gmail.com</p>

[pt] As crises climática e de biodiversidade que afetam o planeta requerem mudanças profundas nos modelos socioeconômicos que têm sido apontados como uma das causas da degradação ambiental recente. Valores e comportamentos adotados pela sociedade moderna são uma das maiores ameaças à integridade dos processos naturais. A interação da humanidade com o meio ambiente é parte de um sistema socioecológico no qual é possível intervir para reverter ou mitigar seus efeitos negativos na natureza. O conceito de pontos de alavancagem propõe a identificação de componentes de um sistema complexo nos quais se pode intervir com grande potencial de mudança nos seus resultados. A conexão das pessoas com a natureza representa um ponto de alavancagem de alto impacto dentro desse sistema, pois tem o potencial de gerar uma nova mentalidade, criar valores e estimular comportamentos favoráveis à causa da sustentabilidade. O contato direto com ambientes naturais preservados, as atividades ao ar livre, a observação da vida selvagem e o conhecimento da história e culturas de determinadas regiões estimulam a conexão das pessoas com o mundo natural, que tem se perdido com o modelo de vida moderno, concentrado em ambientes urbanos e afastado da natureza. A criação de unidades de conservação públicas ou privadas que possam ser acessadas pela população é um importante vetor de conexão das pessoas com a natureza e, portanto, um importante elemento na mudança de valores e comportamentos danosos ao meio ambiente. A partir da apresentação e discussão das bases conceituais da conexão das pessoas com a natureza, este trabalho articula o tema como base para o plano de manejo de uma unidade de conservação privada (RPPN) cujo foco principal é a conexão das pessoas com a natureza, reforçando valores e comportamentos de respeito à vida e ao meio ambiente. / [en] The climate and biodiversity crises affecting the planet require profound changes in socioeconomic models that have been identified as one of the root causes of recent environmental degradation. The values and behaviours adopted by contemporary society stand as a formidable menace to the integrity of natural processes. Human interaction with the environment is a component of a socio ecological system in which it is possible to intervene to reverse or mitigate its negative effects on nature. The concept of leverage points proposes the identification of components of a complex system in which it is possible to intervene with great potential for changing its outcomes. Human-nature connectedness represents a high-impact leverage point within this system, as it has the potential to generate a new mindset, create values and stimulate behaviours favourable to the cause of sustainability. Direct contact with preserved natural environments, outdoor activities, wildlife observation and knowledge of the history and cultures of certain regions stimulate people s connection with the natural world, which has been lost with the modern urban-centric lifestyle. Establishing easily accessible public or private conservation areas plays a crucial role in rekindling this connection between people and nature, consequently serving as a pivotal element in reshaping values and behaviours that harm the environment. This work not only presents but also delves into the foundational concepts underpinning the connection between people and nature. It weaves this theme into the foundation of a management plan for a private reserve (RPPN) that centres around fostering the connection between individuals and the natural world. This endeavour aims to reinforce values and behaviours that revere life and champion nature conservation.
