O impacto das práticas sustentáveis na cadeia de abastecimento no desempenho da empresa

Ao longo da última década, a crescente preocupação com as ameaças suscitadas pelas mudanças climáticas e o esgotamento dos recursos naturais tem-se tornado evidente em diversas indústrias e na população global. Além da salvaguarda do ambiente natural, espera-se, das empresas, que respeitem princípios de equidade social nas suas práticas e processos produtivos. Existe uma perceção generalizada de que as empresas e os diversos governos nacionais devem ser mais eficientes na utilização dos recursos naturais e humanos, de modo a promover um desenvolvimento ambiental, social e económico equilibrado e sustentável. Consequentemente, todas as indústrias serão desafiadas a reorganizar as suas cadeias de abastecimento, preservando o ambiente natural e respeitando as comunidades locais. É neste contexto que se insere a presente investigação, que visa contribuir para a consolidação da teoria da gestão sustentável da cadeia de abastecimento. O objetivo geral deste trabalho é o de identificar e analisar os fatores que induzem e instigam as empresas à implementação de práticas ambientais e sociais, identificar e caracterizar as práticas sustentáveis utilizadas e perceber a relação destas práticas com o desempenho económico, ambiental e social. Para responder aos propósitos fixados para o estudo fez-se uso de uma abordagem qualitativa que integrou estudos de caso múltiplos, constituídos a partir de oito empresas de diferentes setores de atividade, que operam em Portugal, destinados a analisar as estratégias de sustentabilidade desenvolvidas e implementadas por essas das organizações. Ao longo da investigação empírica, identificam-se as práticas ambientais e sociais implementadas nas empresas e nas suas cadeias de abastecimento e os diferentes indicadores que as mesmas utilizam para medição do seu desempenho. Nos casos analisados, são apresentadas evidências de que a gestão sustentável da cadeia de abastecimento requer das empresas a criação de mecanismos formais de cooperação entre os vários membros da cadeia de abastecimento e de que existe uma relação entre a aplicação de práticas sustentáveis e o desempenho económico, ambiental e social.

Uma relação de parceria entre família e escola: contributos para a sua análise no caso de crianças com necessidades educativas especiais

Vários investigadores têm considerado que a relação entre a família e a escola tem um impacto significativo no desenvolvimento da criança e, principalmente no caso de crianças com Necessidades Educativas Especiais (NEE). Atualmente, verifica-se que os serviços de Intervenção Precoce (I.P.) têm procurado envolver as famílias nas suas intervenções, de modo a se promover uma verdadeira parceria, como se encontra sustentado por Correia e Serrano (2002) que defendem que para que se obtenham resultados eficazes é fundamental que os pais participem no processo educativo e na intervenção com a criança. O presente estudo tem como objetivo conhecer a parceria e o envolvimento estabelecido entre Pais e Profissionais de Educação (Educadoras de Infância do Ensino Regular e do Apoio Educativo) face ao apoio de crianças com NEE. Para atingir os objetivos delineados utilizaram-se quatro instrumentos, um questionário sócio-demográfico dirigido a Pais e Profissionais de Educação; um inquérito dirigido aos Pais e outro aos Profissionais de Educação sobre a colaboração e o envolvimento (adaptado de Silva, 2004; Martins, 1996); e o último instrumento, Families in Natural Environment Scale of Services Evaluation (FINESSE). Aos questionários responderam 90 sujeitos (N=90), por 3 grupos amostrais (30 Pais de crianças com NEE, 30 Educadoras do Ensino Regular e 30 Educadoras do Apoio Educativo). Os resultados demonstram que os Pais encontram-se envolvidos e colaboram com o jardim-de-infância da criança e consideram importante o seu envolvimento na I.P.. Observou-se também que a prática típica e a prática ideal das Profissionais de Educação se aproxima, mas não corresponde exatamente à prática idealmente recomendada em I.P.. Verificou-se que existem relações significativas entre a média da prática ideal e as habilitações literárias das Educadoras do Ensino Regular [H(2)=6,604, p=0,037] e no que diz respeito à média da prática ideal e à idade das Educadoras do Apoio Educativo [H(2)=6,170, p=0,046). No que concerne ás restantes variáveis sóciodemográficas e à média da prática típica e ideal das Profissionais de Educação não se verificam diferença significativas. Diante dos resultados apresentados é essencial que a parceria entre Pais e Profissionais de Educação seja promovida através de estratégias que permitam melhorar essa relação. Torna-se importante responder às necessidades dos técnicos, de modo a que as suas práticas se aproximem das práticas recomendadas.

Towards more sustainable urban forms in the city of Benghazi: a study of urban fragmentation at the neighbourhood level

Urban sprawl is a challenge to the sustainability of many cities around the world. Fragmented urban development and vacant land are widespread problems in many Arab cities (UN-Habitat, 2012) which are, according to Ben-Hamouch, mainly a result of inappropriate modern planning and poor land management (2013). This study addresses the problem of urban fragmentation at the neighbourhood level and examines to what extent the concept of compact urban form can contribute to the improvement of social and environmental sustainability in the Libyan city of Benghazi and Arab cities in general. The objectives and scope of the study have justified a morphological approach, where eleven case studies that present different urban typologies in the city have been investigated. The research strategy and selection of case studies were driven by the availability of data and meant to cover the main urban types and important issues defined within this context. This research, which has been conducted to explore and explain the relationships that exist between local urban forms and their performance in terms of sustainability, has produced valuable knowledge and helped to identify measures which target the improvement of people’s quality of life and environmental sustainability of the city. The research draws on the argument that adopting a type of human scale urban form, which is relatively compact and dense, well-connected and comfortably diverse, coupled with concepts of urban greening and flexible development relevant to the local context, would help to create a high quality urban form that is liveable and accessible, while causing minimum damage to the natural environment. This work is an attempt to respond and add to the ongoing debate on sustainable urban form in the developing countries (see: (Jenks, 2000)). The findings have contributed to the understanding of urban fragmentation and highlighted the relevance of the theory of compact city to sustainable development in Benghazi and the South in general. It is anticipated that this work would raise awareness on the impact of urban fragmentation on the sustainability of the built environment within this context and help to advance research on planning theory and practice based on real-life experience and responses to local circumstances.

Examining Chinese Tourists’ Nature-based Tourism Participantion Behavior: Incorporating Environmental Concern into a Constraint-Negotiation Modela

Finding the balance between economic development and preservation of the natural environment is a challenging yet important task. This is a particularly pressing issue in the case of China, as it is the largest and fastest-growing market for tourism. The purpose of this research is to examine Chinese tourists’ participation in nature-based, tourism activities by incorporating tourists’ environmental concern, measured by a revised New Environmental Paradigm (NEP) scale, into a tourism constraint-negotiation model. The responses of 409 Chinese tourists show environmental concern will positively affect tourists’ motivation, which, in turn, will affect their negotiation strategy and ultimately their participation behavior. The theoretical and managerial implications of this study are discussed in the context of the tourism literature.

The river solofrana bicycle network: a project of green mobility

The article presents the “LungoSolofrana” project, carried out during the course “Urban and Mobility” in the academic year 2009/2010, held during the bachelor in Environmental Engineering at the University of Naples “Federico II”. The work has also been chosen as a finalist at the “UrbanPromo 2010” contest, the urban and territorial marketing event sponsored by the National Institute of Urban Planning and Urbit which was held in Venice in 2010. The project consists in a green mobility proposal, developed with an approach based on the integration of the environmental redevelopment of a portion of river Solofrana, located in the Salerno Province, and of the renewal of seven local stations of the railway line Mercato San Severino – Nocera Inferiore, including the realization of a cycle-path network for the natural environment fruition. Furthermore the work drew attention to the local and regional administration. The main intent of the project is to integrate sustainable mobility themes with the environment recovery in a territory affected by high environmental troubles. The area includes the municipalities of Nocera Inferiore, Nocera Superiore, Mercato San Severino, Castel San Giorgio and Roccapiemonte, situated in Salerno’s province, with a total population about 114.000 (font Demo ISTAT 2010). The area extension is about 84,30 sqkm and it is crossed by river Solofrana that is the central point of the project idea. The intervention strategy is defined in two kinds of actions: internal and external rail station interventions. The external rail station interventions regard the construction of pedestrian-cycle paths with the scope of increasing the spaces dedicated to cyclists and to pedestrians along the river Solofrana sides and to connect the urban areas with the railway station. In this way, it’s also possible to achieve an urban requalification of the interested area. On the other side, the interventions inside the station , according to Transit Oriented Development principles, aim at redeveloping common spaces with the insertion of new activities and at realizing new automatic cycle parks covered by photovoltaic panels. The project proposal consists of the urban regeneration of small railway stations along the route-Nocera-Codola Mercato San Severino in the province of Salerno, through interventions aimed at improving pedestrian accessibility. The project involves in particular the construction of pedestrian paths protected access to the station and connecting with neighboring towns and installation of innovative bike parking stations in elevation, covering surfaces coated with solar panels and spaces information. The project is aimed to propose a new model of sustainable transport for small and medium shifts as an alternative to private transportation

Se presenta la escala de madurez gonadal del lenguado Paralichthys adspersus, elaborada en base al análisis y procesamiento histológico de 96 ovarios y 66 testículos de ejemplares capturados en la costa central del Perú y mantenidos en cautiverio. Los ovarios fueron clasificados micro y macroscópicamente, teniendo en cuenta el desarrollo de gametos y gonadas en: virginal, reposo, en maduración, maduro, desovante y recuperación; y a los testículos en virginal, reposo, en maduración, maduro, expulsante y post expulsante. La comparación de las características macro y microscópicas de las gónadas de peces en cautiverio no mostraron ninguna diferencia con respecto a las gónadas de los peces en su ambiente natural.

CCK, dietary variety, and food intake in rats /

Among the environmental factors that can affect food intake is the extent of dietary variety available in the environment. Numerous studies have demonstrated that variety in a meal can increase the amount of food consumed in humans, rats, and other species. A physiological mechanism that has been demonstrated to affect food intake is the gut peptide cholecystokinin (CCK) which is released from the upper small intestine during the ingestion of food. Peripherally administered CCK has a robust inhibitory effect on the intake of a single-food meal. Thus, dietary variety and CCK both affect meal size, with dietary variety increasing intake and CCK decreasing intake. This raises the question ofhow dietary variety and CCK might interact to affect meal size. Previous studies of CCK's effects have focused on situations in which only one food was available for consumption. However, in an animal's natural environment it would frequently occur that the animal would come across a number of foods either simultaneously or in quick succession, thus providing the animal access to a variety of foods during a meal. Accordingly, the effect ofCCK on food intake in single-food and multiple-food meals was examined. It was found that food intake was greater in multiple-food than in single-food meals provided that foods in the multiplefood meal were presented either simultaneously or in increasing order of preference. When foods in the multiple-food meal were presented in decreasing order of preference, intake was similar to that observed in single-food meals. In addition, it was found that CCK inhibited food intake in a dose-dependent manner, and that its effects on food intake were similar regardless of meal type. Therefore, the inhibitory effects ofCCK were not diminished when a variety of foods were available for consumption. Furthermore, the finding that CCK did not differentially affect the intake of the two types of meals does not provide support for the recent-foods hypothesis which postulates that CCK decreases food intake by reducing the palatability of only recently consumed foods. However, it is consistent with the all-foods hypothesis, which predicts that CCK reduces food intake by decreasing the palatability of all foods. The 600 ng/kg dose of the CCK^-antagonist lorglumide significantly antagonized the inhibitory effect of exogenous CCK on food intake, and the magnitude of this effect was similar for both types of meal. These results suggest that exogenous CCK inhibits food intake through the activation ofCCK^ receptors. However, when administered by itself, the 600^ig/kg dose of lorglumide did not increase food intake in either single-food or multiple-food meals, suggesting that peripheral endogenous CCK may not play a major role in the control of food intake.

Buddhism and the earth : environmental thought in early Buddhist philosophy

Introduction Fundamental to the philosophy of Buddhism, is the insight that there is "unsatisfactohness" (dukkha) in the world and that it can be eliminated through the practice of the Noble Eight Fold Path. Buddhism also maintains that the world as we experience and entities that exist are bereft of any substantiality. Instead existence is manifest through dependent origination. All things are conditional; nothing is permanent. However, inherent in this dependent existence is the interconnectedness of all beings and their subjection to the cosmic law of karma. Part of cultivating the Eight Fold path includes a deep compassion for all other living things, 'trapped' within this cycle of dependent origination. This compassion or empathy (karuna) is crucial to the Buddhist path to enlightenment. It is this emphasis on karuna that shows itself in Mahayana Buddhism with respect to the theory of the boddhisatva (or Buddha-to-be) since the boddhisatva willingly postpones his/her own enlightenment to help others on the same path. One of the ramifications of the theory of dependent origination is that there is no anthropocentric bias placed on humans over the natural world. Paradoxically the doctrine of non-self becomes an ontology within Buddhism, culminating in the Mayahana realization that a common boundary exists between samsara and nirvana. Essential to this ontology is the life of dharma or a moral life. Ethics is not separated from ontology. As my thesis will show, this basic outlook of Buddhism has implications toward our understanding of the Buddhist world-view with respect to the current human predicament concerning the environment. While humans are the only ones who can 4 attain "Buddhahood", it is because of our ability to understand what it means to follow the Eight fold path and act accordingly. Because of the interconnectedness of all entities {dharmas), there is an ontological necessity to eliminate suffering and 'save the earth' because if we allow the earth to suffer, we ALL suffer. This can be understood as an ethical outlook which can be applied to our interaction with and treatment of the natural environment or environment in the broadest sense, not just trees plants rocks etc. It is an approach to samsara and all within it. It has been argued that there is no ontology in Buddhism due to its doctrine of "non-self". However, it is a goal of this thesis to argue that there does exist an original ontology in Buddhism; that according to it, the nature of Being is essentially neither "Being nor non-being nor not non-being" as illustrated by Nagarjuna. Within this ontology is engrained an ethic or 'right path' (samma marga) that is fundamental to our being and this includes a compassionate relationship to our environment. In this dissertation I endeavour to trace the implications that the Buddhist worldview has for the environmental issues that assail us in our age of technology. I will explore questions such as: can the Buddhist way of thinking help us comprehend and possibly resolve the environmental problems of our day and age? Are there any current environmental theories which are comparable to or share common ground with the classical Buddhist doctrines? I will elucidate some fundamental doctrines of early Buddhism from an environmental perspective as well as identify some comparable modern environmental theories such as deep ecology and general systems theory, that seem to share in the wisdom of classical Buddhism and have much to gain from a deeper appreciation of Buddhism.

Socially Constructed Environmental Issues and Sport: A Content Analysis of Ski Resort Environmental Communications

Due to the impact of sport on the natural environment (UN, 2010), it is important to examine the interplay between environmental issues and sport (Hums, 2010, Mallen & Chard, 2011; Nauright & Pope, 2009; Ziegler, 2007). This research content analyzed 82 ski resort environmental communications (SRECs). These communications were rated for their prominence, breadth, and depth using the delineation of environmental issues provided by the Sustainable Slopes Program (SSP) Charter. This data was compared to the resorts’ degree of environmentally responsible action as rated by the Ski Area Citizens’ Coalition (SACC). An adaptation of Hudson and Miller's (2005) model was then used to classify the ski resorts as inactive, reactive, exploitive, or proactive in their environmental activities. Recommendations have been made for standardization and transparency in environmental disclosures and an environmental management system to aid ski resorts in moving from ad hoc processes to a systematic and comprehensive framework for improving environmental performance.

Greener Golf Operations: A Comparative Case Study of Ontario Golf Courses Engaged in Environmental Sustainability Initiatives

This research explored environmental sustainability (ES) initiatives at five top-ranked Ontario golf courses that were members of the Audubon Cooperative Sanctuary Program for Golf (ACSP). Research Questions: (1) How are golf courses adapting to safeguard the natural environment? (2) Why or why not are golf courses moving to ES? and (3) What are the arising barriers to ES in golf and how can they be overcome; what role does communication play? Overall, the research was framed with an adaptation of the dimensions of convergence by Houlihan (2012), including the motives, inputs, implementation, momentum, and impact. Additionally, impression management and message framing constructs were utilized to address the issue of communicating ES initiatives. Data collection involved in-depth interviews, observations, and unobtrusive document collection. Environmental aspects of the examination were guided by the Canadian Standards Association (CSA) Requirements and Guidance for Organizers of Sustainable Events and Sustainable Sport and Event Toolkit (SSET).
