Turismo sustentável e educação ambiental nos parques naturais de Montesinho e Douro Internacional

Esta Tese insere-se no âmbito das Ciências e Engenharia do Ambiente e aborda as temáticas do Turismo Sustentável, Educação Ambiental e Áreas Protegidas. Na atualidade o turismo é considerado como um dos fenómenos sociais e económicos mais importantes e um instrumento com grande importância para o desenvolvimento dos países e regiões. A discussão em torno do conceito de turismo sustentável, embora nem sempre coincidentes, orienta para uma conceção onde a componente ambiental, social e económica constituem as principais dimensões que devem ser consideradas no seu desenvolvimento. As áreas protegidas são territórios cuja principal função é conservação do ambiente. Estes espaços protegidos possuem um conjunto de recursos que os potenciam para o desenvolvimento do turismo sustentável e educação ambiental contribuindo, desta forma, para o desenvolvimento sustentado das regiões. Atualmente o turismo sustentável e a educação ambiental são uma realidade cada vez mais presente nas áreas protegidas contribuindo com benefícios sociais, económicos e para o desenvolvimento sustentável das regiões. Pretendeu-se com este trabalho analisar as opiniões e perceções dos visitantes, dos responsáveis dos empreendimentos turísticos, das associações locais e os dirigentes políticos, sobre o turismo sustentável e educação ambiental nos Parques Naturais de Montesinho e Douro Internacional com vista à apresentação de iniciativas para o seu desenvolvimento.Para a concretização deste desiderato geral foi selecionada uma metodologia que englobou, por um lado, uma análise empírica, através da implementação de inquérito por questionários aos visitantes dos Parques Naturais de Montesinho e Douro Internacional. A recolha de informação junto dos empreendimentos turísticos e associações locais, inseridos nos territórios dos parques naturais. Por outro lado, o inquérito por entrevista foi o instrumento de recolha de informação utilizado junto dos responsáveis políticos dos Concelhos que integram os Parques Naturais de Montesinho e Douro Internacional. Dos resultados obtidos, destaca-se que os visitantes, na maioria, são pessoas que visitaram estes parques pela primeira ou segunda vez, não ficam alojados na área e visitaram o parque acompanhados. Salienta-se a opinião favorável, destes, sobre a existência de áreas protegidas em Portugal e sobre a contribuição que estas podem dar para a conservação do ambiente, representando um recurso importante para as gerações futuras. Destaca-se, também, a opinião positiva sobre a visita aos parques e a consideração de que é importante o desenvolvimento do turismo e da educação ambiental. Em relação aos empreendimentos turísticos que participaram no estudo verificou-se que são, principalmente da tipologia de espaço rural. Além da oferta de alojamento, alguns empreendimentos turísticos disponibilizam atividades turísticas nos parques. Os responsáveis são da opinião que os parques são uma mais-valia para a região e tem uma opinião favorável sobre o desenvolvimento do turismo sustentável nas áreas em estudo. No que concerne às associações, verificou-se que as atividades que desenvolvem não estão vocacionadas para o turismo e educação ambiental. No entanto, estas associações também consideram importante a existência dos parques na região e que o turismo sustentável e a educação ambiental são duas componentes complementares que podem contribuir para o desenvolvimento sustentável das áreas dos parques. A opinião dos dirigentes dos municípios que integram os parques naturais de Montesinho e Douro Internacional orienta-se no mesmo sentido. Estes são de opinião que é necessário desenvolver uma estratégia e implementar medidas para o desenvolvimento do turismo sustentável nos parques naturais. Esperamos que os resultados desta investigação possam, de alguma forma, contribuir para orientar as iniciativas e ações de desenvolvimento do turismo sustentável e educação ambiental dos diversos agentes que atuam nos Parques Naturais de Montesinho e Douro Internacional.

Brazilian savanna forest : conservation, medicinal reservoir and bioprospecting

This study aimed to analyse the Brazilian savanna forest from a Legal Reserve (LR) area from a perspective of conservation, reservoir of organic carbon and medicinal biomass for a prospective use of native medicinal plants. An ethnobotanical and ethnopharmacological survey was carried out close to a community settled in the rural area in the south of Tocantins, being selected 9 of the most cited species (cajuí- Anacardium othonianum; inharé-Brosimum gaudichaudii; jatobá-Hymenaeae courbaril; jenipapo-Genipa americana, aroeira-Myracrodruon urundeuva; negramina-Siparuna guianensis; barbatimão- Stryphnodendron obovatum; assa peixe-Vernonia brasiliana, embaúba-Cecropia pachystachya). Crude foliar extracts were subjected to a preliminary phytochemical prospection and triage of secondary metabolites with antimicrobial activity of potential interest in health and familiar agriculture. Phenolic compounds, terpenes and flavonoids were detected in the extracts of most species, which suggests the presence of antimicrobial, antioxidant and anti-insect activities. It was evident the need to better know the LR as a reservoir of medicinal biomass in an area under ecological tension where 35% (610ha) of the property is LR and should be protected by law. Therefore, a forest inventory of live woody species was performed using the allometric or indirect method. This identified a rare remnant of Semidecidual Seasonal Forest amidst the largest world savannah, the Cerrado biome. An analysis of the forest average productivity per basal area (m².ha), aerial live biomass (ton.ha-1) and carbon stock was carried out. The forest fragment was considered relatively rich in species and diversity, although showing signs of disturbance and dominance by a few species. Its horizontal structure suggests biotic regeneration conditions. It is an important reservoir of medicinal plants. Of the families (57.5%) presenting medicinal species, 19 from a total of 33 are represented in the area and contain 44% (27) of the total species (61) and 63% (432) of the total individuals catalogued. Medicinal species have ecological importance for the equilibrium of the local flora and represent 80% of the 10 species with higher Importance Value Index (IVI): Tetragastris altissima, Chrysophyllum marginatum, Oenocarpus distichus, Sclerolobium paniculatum, Simarouba versicolor, Alibertia macrophylla, Siparuna guianensis, Maprounea guianensis, Licania parvifolia e Physocalymma scaberrimum. Medicinal productivity was high for this type of phytophysionomy: 183,2 ton. ha-1 of biomass and 91,51 ton. ha-1 of carbon representing 66% of the total biomass and carbon of this Cerrado forest. From this stage S. guianensis (Siparunaceae) was selected for performing bioassays in order to verify its biological activity against microorganisms of health and agricultural relevance. This is a native aromatic medicinal plant recommended as priority for conservation, with local popular medicinal validation and availability of medicinal feedstock (3300 Kg.ha-1), with the foliar fraction giving 38Kg/ha of crude extract and 5L/ha of essential oil. Foliar crude extracts and essential oil were obtained and tested in vitro using a disk diffusion bioassay. Different concentrations of these natural products were tested against gram-positive bacteria (Staphylococcus aureus ATCC 29213), gram-negative bacteria (Escherichia coli ATCC 25922 and ATCC 35218; Pseudomonas aeruginosa ATCC 10145) and fungi (Candida albicans ATCC 6258 e Fusarium oxysporum). The essential oil inhibited the growth of S. aureus in its crude concentration (380μg.mL-1), as well as diluted to half (190μg.mL-1) and a quarter strength (95μg.mL-1). It’s likely that such action is due to sesquiterpenes major components, such as bisabolol and bisabolene (10.35%), measured by gas chromatography (GC-MS, GC-FID). Extracts did not exhibit any antimicrobial activity against the microorganisms tested. The native medicinal plants prospective market is an alternative that favours the conservation of biodiversity while generating benefits for the development of sustainable family productive activities within local ecosystems instead of the current inappropriate uses. This strengthens conservation policies of Legal Reserve in rural settlements and is in agreement with public policy on global warming and climate changes.

Spirituality and Basketball Fanship: An Interpretative Phenomenological Analysis and Synthesis

The world of competitive sport affords an individual the opportunity to enter a spiritual community adding meaning that transcends one’s current understanding of life (Parry et al. 2007). Previously established dimensions of sports fanship (group affiliation, psychological commitment and team identification) share characteristics commonly associated with religious or spiritual affiliation indicating that fans may generate substantial life meaning from observing sporting encounters. In the present study, 12 male basketball fans (M=32.42; SD=7.97) completed semi-structured interviews immediately prior to viewing a competitive match at the 2011 European Basketball Championships (Vilnius, Lithuania). Interviews were structured under four headings; 1) the most memorable moment as a basketball fan, 2) thoughts, feelings and emotions attached to their team, 3) affiliation to the team in the context of the fan’s meaning of life, 4) connection with members of the fan’s sporting community. Interpretative Phenomenological Analysis was employed to analyse interview transcripts. Raw data clustered into four dimensions; 1) devotion, 2) obscure emotions, 3) connectedness, and 4) universal values. The results indicate that sports fanship is characterised by, and synonymous with, an established understanding of spirituality derived from membership of wider spiritual and/or religious communities. The findings hold implications for the marketing and membership of local, amateur and professional sports clubs and brands, as well as community development, health and welfare.

Spatial and temporal assessment of sediment contamination in Sado estuary: a methodological approach

For better management of estuarine ecosystems their contamination assessment should be easily communicated to local managers and decision makers. The problem is the lack of available data and the search of methodologies to enable that assessment using only few data. The Sado estuary in Portugal is as good example of a site where human pressures and ecological values collide with each other and where the degree of metal and organic contamination has not been subject to an overall assessment, either in terms of spatial or temporal variability, in a way that managers can understand.

Creativity and problem solving in the development of organizational innovation

This research focuses on creativity and innovation management in organizations. We present a model of intervention that aims at establishing a culture of organizational innovation through the internal development of individual and team creativity focusing on problem solving. The model relies on management’s commitment and in the organization’s talented people (creative leaders and employees) as a result of their ability in defining a better organization. The design follows Min Basadur’s problem solving approach consisting of problem finding, fact finding, problem definition, solution finding and decision implementation. These steps are carried out using specific techniques and procedures that will link creative people and management in order to initiate the process until problems are defined. For each defined problem, project teams will develop possible solutions and implement these decisions. Thus, a system of transformation of the individual and team creativity into organizational innovation can be established.

Genetic structure at range edge: Low diversity and high inbreeding in Southeast Asian mangrove (Avicennia marina) populations

Understanding the genetic composition and mating systems of edge populations provides important insights into the environmental and demographic factors shaping species’ distribution ranges. We analysed samples of the mangrove Avicennia marina from Vietnam, northern Philippines and Australia, with microsatellite markers. We compared genetic diversity and structure in edge (Southeast Asia, and Southern Australia) and core (North and Eastern Australia) populations, and also compared our results with previously published data from core and southern edge populations. Comparisons highlighted significantly reduced gene diversity and higher genetic structure in both margins compared to core populations, which can be attributed to very low effective population size, pollinator scarcity and high environmental pressure at distribution margins. The estimated level of inbreeding was significantly higher in northeastern populations compared to core and southern populations. This suggests that despite the high genetic load usually associated with inbreeding, inbreeding or even selfing may be advantageous in margin habitats due to the possible advantages of reproductive assurance, or local adaptation. The very high level of genetic structure and inbreeding show that populations of A. marina are functioning as independent evolutionary units more than as components of a metapopulation system connected by gene flow. The combinations of those characteristics make these peripheral populations likely to develop local adaptations and therefore to be of particular interest for conservation strategies as well as for adaptation to possible future environmental changes.

Optical and mechanical analysis on a biological cell in optical tweezers

La réponse mécanique d’une cellule à une force externe permet d’inférer sa structure et fonction. Les pinces optiques s’avèrent une approche particulièrement attrayante pour la manipulation et caractérisation biophysique sophistiquée des cellules de façon non invasive. Cette thèse explore l’utilisation de trois types de pinces optiques couramment utilisées : 1) statiques (static), 2) à exposition partagée (time-sharing) et 3) oscillantes (oscillating). L’utilisation d’un code basé sur la méthode des éléments finis en trois dimensions (3DFEM) nous permet de modéliser ces trois types de piégeage optique afin d’extraire les propriétés mécaniques cellulaires à partir des expériences. La combinaison des pinces optiques avec la mécanique des cellules requiert des compétences interdisciplinaires. Une revue des approches expérimentales sur le piégeage optique et les tests unicellulaires est présentée. Les bases théoriques liant l’interaction entre la force radiative optique et la réponse mécanique de la cellule aussi. Pour la première fois, une simulation adaptée (3DFEM) incluant la diffusion lumineuse et la distribution du stress radiatif permet de prédire la déformation d’une cellule biconcave –analogue aux globules rouges—dans un piège statique double (static dual-trap). À l’équilibre, on observe que la déformation finale est donnée par l’espacement entre les deux faisceaux lasers: la cellule peut être étirée ou même comprimée. L’exposition partagée (time-sharing) est la technique qui permet de maintenir plusieurs sites de piégeage simultanément à partir du même faisceau laser. Notre analyse quantitative montre que, même oscillantes, la force optique et la déformation sont omniprésentes dans la cellule : la déformation viscoélastique et la dissipation de l’énergie sont analysées. Une autre cellule-type, la tige cubique, est étudiée : cela nous permet d’élucider de nouvelles propriétés sur la symétrie de la réponse mécanique. Enfin, l’analyse de la déformation résolue en temps dans un piége statique ou à exposition partagée montre que la déformation dépend simultanément de la viscoélasticité, la force externe et sa forme tridimensionnelle. La technique à force oscillante (oscillating tweezers) montre toutefois un décalage temporel, entre la force et la déformation, indépendant de la forme 3D; cette approche donnerait directement accès au tenseur viscoélastique complexe de la cellule.

ILS and RTP: Support to Researchers Provided by Information and Learning Services as Part of the Research Training Programme at the University of Worcester, Past, Present and Future.

The purpose of this article is to investigate the involvement of Information and Learning Services staff in the delivery of the Research Training Programme at the University of Worcester, UK with a focus on researcher receptivity. I believe that by constantly reflecting on the development of that part of the programme delivered by ILS and by examining feedback from the sessions, it is possible to improve and increase the level of researcher receptivity. It is hoped that such examination and reflection will be of value and relevance to the IL community since by reflecting on success and failure in a local context and by mapping this reflection to existing research enables librarians to improve the support provided to researchers within their institutions. This article outlines the support given to research students at the University of Worcester in the past, examines the changes leading to present programme delivery and reflects on considerations for future support. The article is underpinned by reference to current research undertaken in international (albeit Western-centric) contexts. I note that the rationale behind changes is embedded in current adult learning and teaching theory. In an increasingly competitive research environment where funding is dependent on a statistically monitored research output, the aim of such support is to integrate any IL contribution into the wider research training programme. Thus resource discovery becomes part of the reflexive research cycle. Implicit in this investigative reflection is the desire of the IL community to constantly strive towards the positive reception of IL into research support programmes which are perceived by researchers as highly valuable to the process and progress of their work.

Understanding community empowerment in urban regeneration and planning in England: putting policy and practice in context

Community involvement in the fields of town planning and urban regeneration includes a wide range of opportunities for residents and service users to engage with networks, partnerships and centres of power. Both the terminology and degree of the transfer of power to citizens varies in different policy areas and contexts but five core objectives can be identified. This article approaches the subject of community empowerment by exploring the theoretical literature; reviewing recent policy pronouncements relating to community involvement in England and by discussing a recent case study of an Urban II project in London. The conclusions suggest that community empowerment is always likely to be partial and contingent on local circumstances and the wider context.

Investigating the causal role of rightOFA in holistic detection of Mooney faces and objects: an fMRI-guided TMS study

Background The right occipital face area (rOFA) is known to be involved in face discrimination based on local featural information. Whether this region is involved in global, holistic stimulus processing is not known. Objective We used fMRI-guided transcranial magnetic stimulation (TMS) to investigate whether rOFA is causally implicated in stimulus detection based on holistic processing, by the use of Mooney stimuli. Methods Two studies were carried out: In Experiment 1, participants performed a detection task involving Mooney faces and Mooney objects; Mooney stimuli lack distinguishable local features and can be detected solely via holistic processing (i.e. at a global level) with top-down guidance from previously stored representations. Experiment 2 required participants to detect shapes which are recognized via bottom-up integration of local (collinear) Gabor elements and was performed to control for specificity of rightOFA's implication in holistic detection. Results In Experiment 1, TMS over rOFA and rLO impaired detection of all stimulus categories, with no category-specific effect. In Experiment 2, shape detection was impaired when TMS was applied over rLO but not over rOFA. Conclusions Our results demonstrate that rOFA is causally implicated in the type of top-down holistic detection required by Mooney stimuli and that such role is not face-selective. In contrast, rOFA does not appear to play a causal role in in detection of shapes based on bottom-up integration of local components, demonstrating that its involvement in processing non-face stimuli is specific for holistic processing.
