description: I see an elision or lacuna in these proceedings, possibly signif-icant: the lack of discussion, in a conference rather inspired to speculate  objects  in  the  mirror  of  medieval  works,  of  the  me-dieval origins of the concept and word object. Is this an over-sight, a structural failure of vision to bump into what it ought to  see?  Or  is  it  a  purer  kind  of  non-event,  the  causeless  not-happening  of  something?  Sometimes  I  get  the  feeling  that what  does not  h appen  is  inexplicably  powerful,  an  abyssically negative  spontaneity  ruling  and  seducing  all  existent  things from  its  universal  invisible  domain.  The  issue  might  provide an  interesting  playground  for  thinking  the  objecthood  of  the inexistent,  of  what  is  not there.  This  is  a  good  limit-problem for  any  philosophy  wanting  to  relate  to  reality  as  constituted by how things are. It is also a question that the medieval, as a zone  where  a  saint  recommends  preaching  to  non-existent creatures,  philosophers  theorize  divine  alteration  of  the  past, and mystics see nonbeing as an excess of being, is already an-swering.But  I  prefer  not  to  go  there,  wishing  that  I  could  instead move  (or  realize  that  I  am  only  ever  moving)  like  the  guild navigator in David Lynch’s Dune: “I did not say this. I am not here.”  Instead  I  will  close  the  event  by  trying  to  open  it  into some  avenues  of  understanding  along  which  the  medieval origination  of object  might  lead  the  way.  To  find  the  start  of these avenues, imagine a generic medieval intellectual, that is, someone  infused  with  ‘the  love  of  learning  and  the  desire  for God,’  encountering  contemporary  object-orientedness.  First the  bad  news:  there  is  no  absolute  knowledge,  no  arriving  at the  omnipresent  center.  Then  the  good  news:  we  really  have figured  out  what  everything  is:  objects.  Bad  news:  objects  in-commensurably  withdraw,  remain  irreducible  to  relation,  are never knowable in themselves, so no theosis, henosis, subject-object  union,  incarnation,  soul-body  suppositum,  eternal  in-dividuals, or anything like that. Good news: it is because of the above that anything is happening at all . . . and so forth. May-be the fellow would find relief, like a good bloodletting, in the demotion  of  his  desire  from  the  desire  to  be  everything  to  a desire to be with things. Perhaps he would despair. Perhaps he would think he was in paradise, intoxicated with the idea that these  objects  are  God.  Or  perhaps  he  would  object,  discover-ing  new  truth  through  his  own  understanding  of  the  word object

description: This paper aims to highlight the importance of tourism to strengthen the capacities of the different regions and their resources. With this goal in mind an empirical study was conducted in a tourist destination located in the inner part of Portugal (Beira Interior), which aimed to measure the satisfaction obtained by tourists and also to identify the elements of the supply that the demand considers more important to choose this destination. The research stated that the symbolic aspects related to the specific resources of the region were the most important elements that help tourists to choose their destination and the same elements are also those that make tourists more satisfied. Assuming that the symbolic contents are in fact the underlying identity of the region, one can conclude that the more the identity of the region is reinforced, the more the difference is motivating and the more this identity is a key factor of its attractiveness.

Evolução urbana e turistificação dos lugares: um olhar sobre o Rio de Janeiro
Creators: name: Machado, Marcello De Barros Tomé
Publisher: name: Revista Turismo & Desenvolvimento
Year: 2010

description: O Rio de Janeiro no início do século XX era considerado para os padrões da época uma cidade feia e insalubre, longe, portanto, de ser uma cidade moderna e turisticamente atrativa. Mas como o Rio de Janeiro veio a transformar-se numa das mais belas e atrativas cidades do Mundo? A fim de elucidar relevante indagação, definimos como objetivo desta pesquisa a análise do processo de evolução da estrutura urbana do Rio de Janeiro durante a primeira década do século XX, caracterizando o Turismo como indutor e, ao mesmo tempo, produto do projeto urbanístico da cidade do Rio de Janeiro. A metodologia utilizada nesta pesquisa foi baseada essencialmente na análise crítica de fontes primárias e principalmente documentos secundários, com destaque para a imprensa da época, responsável por farto material textual e iconográfico que muito contribuiu para a construção deste trabalho. Ressaltamos também que o embasamento teórico adotado neste trabalho visa articular as categorias e conceitos coerentes com a temática urbano-turística, na tentativa de relacionar o surgimento do Turismo na cidade do Rio de Janeiro ao processo de evolução urbana do espaço carioca. A análise preliminar desta pesquisa aponta para o processo de estruturação do espaço urbano carioca, como determinante para a turistificação da Cidade do Rio de Janeiro no período em questão.

description: Almost one in every three people worldwide is infected with Toxoplasma gondii (T. gondii). The biology and growth of the parasite’s bradyzoite form in host tissue cysts are not well understood. T. gondii’s metabolic state influences the morphology of its single mitochondrion, which can be visualized using fluorescence microscopy with specific dyes. Hence, fluorescence microscopy images of cysts purified from infected mouse brains carry biological information about bradyzoites, the poorly understood form of the parasite within them. With the help of fluorescence microscopy techniques, previous studies extracted images of the mitochondrion, nucleus, and the inner membrane complex (IMC) providing information on T. gondii’s cysts paving the way for image processing techniques and machine learning to analyze the bradyzoite form of the parasite. Previously, multivariate logistic regression (MLG) was used to classify shapes of mitochondrion. In the present study, in addition to the previously used MLG model, two other machine learning models, Support Vector Machine (SVM) and K Nearest Neighbors (KNN), were used to explore the possibility of better model selection for mitochondrial classification. A minimal model error was used to optimize the classification model performance. Error in any machine learning model is driven by bias, variance, and noise. Through trial and error, the optimal hyperparameters for each model were selected to minimize error. The dataset used consisted of 1940 labeled mitochondrial objects with 22 features, and consisted of five classes Blob, Tadpole, Donut, Arc, and Other. 50% of the dataset was used for training, and the other 50% was used for testing. The overall models’ accuracy of MLG, SVM, and KNN were 79.1%, 78.9%, and 80.3% respectively. Overall classification performance did not vary, but the F score for some classes like Tadpole and Donut showed improvement when using the two newer models. One of the 22 features used was an application of the Histogram of Oriented Gradients (HOG). The HOG feature was replaced with a novel feature that used linear regression of object boundary segments to extract the HOG for only the object’s boundary. The model that used Boundary HOG showed some improvement over the HOG feature. Finally, a new module including a graphical user interface was developed to process and extract shape and intensity information from TgIMC3 images which facilitate further investigations of the parasite biology.

description: A cidade do Conde está localizada no Norte do litoral do Estado da Bahia no Brasil, à margem da rodovia Linha Verde. Sua economia gira em torno da agricultura, mas outras atividades não-agrícolas fazem parte a economia do município, como é o caso do turismo. O objetivo desse estudo foi analisar os modelos de comunicação rural desenvolvido pela Administração Municipal do Conde na formação do Conselho Municipal de Turismo, que é composto por diferentes segmentos da sociedade civil organizada. A análise centra-se na representação dos pescadores neste Conselho através da Colônia de Pescadores. Foi definido como espaço da pesquisa o cotidiano dos pescadores por entender que é no cotidiano que essa categoria social produz, reproduz e dá sentido a sua vida. As técnicas de pesquisa foram a observação participante e as entrevistas semi-estruturadas. As conclusões indicam que não existe, de fato, Conselho Municipal de Turismo. Dessa forma, o modelo de comunicação utilizado para compor o Conselho foi o pseudo-participativo. Como a atividade pesqueira no Conde encontra-se em crise devido à ação predatória dos barcos pesqueiros, o turismo surge como uma atividade “redentora” para a população pesqueira, que já a incorporou na sua vida cotidiana.

description: O objetivo principal desta pesquisa científica foi o de analisar os instrumentos de participação popular no processo de concepção das políticas públicas na Amazônia, tendo como recorte o Proecotur (Programa de Desenvolvimento do Ecoturismo na Amazônia Legal), no município de Belém do Pará. Para isso, investigamos as diferentes práticas de participação popular que estão sendo desenvolvidas pelo Programa, mais especificamente nas comunidades de Caruaru e do Porto Pelé, distrito de Mosqueiro. Os resultados obtidos apontaram um baixo grau de participação popular na decisão de políticas públicas de turismo, resultado esse relacionado, principalmente, à dificuldade de acesso ao sistema educacional. Hoje, apesar dos avanços na busca por organização coletiva pela sociedade civil, na prática não observamos números significativos em termos de conquistas de benefícios sócio-econômicos.

title: Development of deep learning modules for autonomous navigation in marine and aerial robotic applications
Creators: name: Balasooriya, Narmada M.
Publisher: name: Memorial University of Newfoundland
Year: 2024

description: This thesis develops two studies on deep learning-based autonomous navigation systems for marine and aerial field robotic applications. The first study involves developing a sea ice detection module to support the autonomous navigation of icebreakers using image semantic segmentation. This module aims to distinguish sea ice from water, sky, and the ship’s body when images captured onboard an icebreaker are received from a shipborne camera. The study compares the performance of the previous work on sea ice detection by the PSPNet model with a new-state-of-the art image semantic segmentation model called DeepLabv3. To evaluate the DeepLabv3 model, it is transfer-learned on the same image data used for the PSPNet model. The performance of both models is tested on a navigation module equipped with a Jetson AGX Xavier developer kit using standard evaluation metrics. The second study contains the development of a landing zone detection pipeline using Lidar semantic segmentation to support the vertical take-off and landing vehicle autonomy. The study evaluates different point cloud semantic segmentation approaches for their compatibility with the landing zone detection task. The main objective of this study is to use only the Lidar data to detect safe landable zones using deep learning-based architectures and to achieve an accuracy-runtime trade-off for real-time operations. The performance of the neural network models for point cloud semantic segmentation is evaluated using standard metrics and different variations of aerial Lidar data. The study also assesses the feasibility of integrating the landing zone detection module into a visual Lidar odometry and mapping pipeline for faster inference by the neural network models.
Enoturismo em Portugal: forma de desenvolvimento regional e afirmação cultural local

description: O Enoturismo é um fenómeno característico de Modernidade, com uma dupla valência e significado: constitui-se como uma actividade turística complementar à oferta turística nacional, predominantemente balnear. Encerra produtos turísticos onde o interesse pelo conhecimento do vinho e da vinha nas suas dimensões material, cultural e gastronómica, ou seja, simbólica, se materializam. Pode revelar-se uma actividade complementar da actividade rural e agro-vitivinícola, ou motor de outras actividades tradicionais, seguindo uma lógica de “pluriactividade”. Mundialmente esta bivalência é reconhecida. Em Portugal, esta actividade encontra-se ainda na sua primeira idade. O presente estudo tem por objectivo o entendimento destas lógicas de complementaridade, em que medida proporcionam o desenvolvimento rural e a afirmação cultural que o encerra. A opção de análise de escala regional permite melhor retratar as suas especificidades, optando-se pelas regiões do Minho, Douro, Alentejo e Setúbal. Formula-se como hipótese que, o Enoturismo é de particular relevância para estas regiões, não tanto pelos postos de trabalho ou lucros gerados, mas pelos processos de interiorização do prestígio e do valor que o trabalho da “arte de fabricar o vinho” induz. Esta imagem de um rural interessante para quem visita e prestigiante para quem nele participa podem constituir uma alavanca de dinâmicas locais necessárias à sua perpetuação e fixação de populações. Propõe-se, em certa medida, a “comercialização” do espaço rural, dos produtos e culturas, do passado e do presente, de forma a garantir-lhes um futuro.

description: Very recently the effect of equisized charged hard sphere solutes in a mixture with core-softened fluid model on the structural and thermodynamic anomalies of the system has been explored in detail by using Monte Carlo simulations and integral equations theory [J. Chem. Phys., 2012, 137, 244502]. Our objective of the present short work is to complement this study by considering univalent ions of unequal diameters in a mixture with the same soft-core fluid model. Specifically, we are interested in the analysis of changes of the temperature of maximum density (TMD) lines with ion concentration for three model salt solutes, namely sodium chloride, potassium chloride and rubidium chloride models. We resort to Monte Carlo simulations for this purpose. Our discussion also involves the dependences of the pair contribution to excess entropy and of constant volume heat capacity on the temperature of maximum density line. Some examples of the microscopic structure of mixtures in question in terms of pair distribution functions are given in addition.

description: Segundo a Organização Mundial do Turismo (OMT), o turismo tem experimentado um contínuo crescimento e profunda diversificação nas últimas décadas, o que lhe tem garantido destaque frente a outros setores da economia. Tal dinâmica o tem posicionado como um dos trunfos para o progresso sócio-econômico de muitas regiões. O turismo rural representa um dos segmentos desse grande setor e é hoje uma das possibilidades de desenvolvimento regional. Especificamente no Brasil, essa modalidade em muitos casos expõe deficiências em seu planejamento e promoção, não contribuindo de forma adequada para o incremento da economia e permanecendo aquém do potencial que realmente poderia conceber. Este trabalho objetiva analisar a aplicação das ferramentas de marketing no turismo rural, com ênfase na promoção do produto e identificar seu estágio atual no município de Lagoa Santa, localizado no Estado de Minas Gerais, Brasil. Para isso, faz-se uma análise dos conceitos de ambiente urbano e rural, assim como uma abordagem do turismo rural, segundo suas organizações estabelecidas pelo governo brasileiro.

On Not Settling the Issue of Realism
Creators: name: Braver, Lee
Publisher: name: punctum books
Year: 2013

description: Philosophy is a means of escape. Our presence in this world is an accident, in both senses of the word, an unfortunate fate that has befallen us as we have fallen into it. This is a world of shadows and reflections, of illusions and elisions, of waste and death. It is a reality in decay that has, paradoxically, always been in decay, a ruins that was never whole.We are in this world, but we do not belong here. We yearn for a reality that is real, and a truth that is true. Since these are not to be found among the detritus of everyday life, we must seek it in a world beyond or behind this one, a realm that truly exists because it has no whiff of non-existence about it—no destruction, no imperfections, no suffering, no death. Our duty in this life is to escape this life, to withdraw physically, emotionally, intellectually, spiritually from these shadows, to slip the bonds that hold us—to escape. And philosophy is what shows us our goal and guides us to it.

description: Food plays an important role in rural development through tourism, especially food routes. Tourists’ demand for discovering regional food is increasing. This paper focuses on olive oil tourism since olive oil is more than a mere product, it is a true culture. A case study analyses three olive oil routes linked to Protected Designations of Origin in the province of Cordoba: Baena, Montoro-Adamuz and Priego de Cordoba. From field work, the supply and the demand for olive oil tourism is analysed. The olive oil routes are not as well known or as frequently visited by the gastronomic tourist as the wine routes and the oil tourism consumer profile is different from the wine tourism consumer profile. However, the olive oil tourism is undoubtedly an opportunity to promote rural development in these areas.

Politics and Speculative Realism
Creators: name: Bryant, Levi R.
Publisher: name: punctum books
Year: 2013

description: Since its birth in 2007, speculative realism (SR) has generated a great deal of controversy in journals, the theory blogosphere, and at conferences. One would search in vain for a unified “speculative realist” position or doctrine. The four original speculative realists who coined the term—Ray Brassier, Gra-ham Harman, Iain Hamilton Grant, and Quentin Meillassoux—argue for very different ontologies and epistemologies, opposed to one another in a number of respects. If there is anything that unites their positions, it is 1) a defense of some variant of realism or materialism, and 2) a critique of correla-tionism. First coined by Meillassoux, correlationism is the thesis that we can only ever speak of being as a correlate of the subject and never the world and subject apart from one another.2 Beyond that, the sort of realism (or materialism) each of these think-ers defends and how they critique correlationism diverges quite substantially.

description: We provide quantitative evidence that the emergence of an effective notion of spacetime locality in black hole physics is due to restricting to the subset of observables that are unable to resolve black hole microstates from the maxi- mally entangled state. We identify the subset of observables in the full quantum theory that can distinguish microstates, and argue that any measurement of such observables involves either long times or large energies, both signaling the breaking down of effective field theory where locality is manifest. We discuss some of the implications of our results for black hole complementarity and the existence of black hole interiors.

title: Task offloading and proactive resource allocation in vehicular edge computing via reinforcement learning
Creators: name: Karimi, Elham
Publisher: name: Memorial University of Newfoundland
Year: 2024

description: Given the rapid increase of various applications in vehicular networks, it is crucial to consider a exible architecture to improve the Quality-of-Service (QoS). Utilizing Multi-access Edge Computing (MEC) as a distributed paradigm with computation capabilities closer to the vehicles can be a promising solution to reduce response time in such a network. However, MEC nodes are deprived of processing all tasks offloaded by the vehicles and suffer from limited resources compared with the central cloud. The offloaded tasks usually have different priorities for processing and various resource demands, and they even are dropped when the response time for task processing expires. Due to the workload dynamics at MEC nodes and the randomness of task arrivals, it is challenging to determine proper MEC servers for task offloading and how to manage resources for the application's demands. This dissertation proposes cooperation between MEC and central cloud decisions for different vehicular application offloading. First, we formulate a new NP-hard resource allocation problem to guarantee the required response time. We transform the environment into a finite Markov decision process that only depends on the current state and action space. We utilize deep reinforcement learning, a proper computational model, to automatically learn the dynamics of the network state and rapidly capture an optimal solution based on the current state and action space. In this dissertation, we develop an intelligent workload prediction of each MEC node utilizing Multivariate Long Short-Term Memory (LSTM) to propose a proactive resource allocation algorithm for various tasks in a dynamic vehicular network. In our algorithm, we classify tasks based on their priorities and migrate the tasks with lower priority to provide service for those with higher priority. Moreover, we apply distributed deep reinforcement learning to solve our problem to increase the efficiency and accuracy of the proactive resource allocation algorithm. Extensive numerical analysis and results illustrate how our proposed algorithms can increase the ratio of accepted high-priority tasks and reduce response time.
O património cultural da região do Alto Tâmega e Barroso como produto turístico

description: Inicialmente ligado à ideia de herança paterna ou familiar, o conceito de património cultural foi sofrendo alterações com o decurso do tempo entendendo-se hoje, não apenas como sinónimo de passado, memória daquilo que ficou como herança, mas também como presente, na medida em que não se pode entender o presente, nem pensar no futuro, sem olhar a “memória”, ou seja, sem que haja uma conjunção de um “antes”, com um “agora” e um “depois”, de forma a criar uma “imagem” representativa do social ou memória social, a que pertencemos. O projecto de investigação a que nos referimos neste artigo nasceu do fascínio e interesse que o património sempre exerceu sobre nós e de forma particular o da região do Alto Tâmega e Barroso. Com ele pretendemos verificar a possibilidade de desenvolver – com base no património cultural - um produto turístico novo, face à necessidade de se diversificar a oferta turística da região em causa, que actualmente está quase exclusivamente voltada para o produto saúde e bem‑estar.

description: RE J1034+396, a narrow-line Seyfert-1 active galactic nucleus (AGN), is the first example of AGNs that exhibited a nearly coherent quasi-periodic oscillation (QPO) for the data collected by XMM-Newton in 2007. The spectral behaviors and timing properties of the QPO have been studied since its discovery. We present an analysis of the QPO in RE J1034+396 based on the Hilbert-Huang transform (HHT). Comparing other time-frequency analysis methods, the Hilbert spectrum reveals the variation of the QPO period in great detail. Furthermore, the empirical mode decomposition provides band-pass filtered data that can be used in the O -- C and correlation analysis. We suggest that it is better to divide the evolution of the QPO in this observation into three epochs according to their different periodicities. In addition to the periodicities, the correlations between the QPO periods and corresponding mean count rates are also different in these three epochs. Further examining the phase lags in these epochs, we found no significant phase lags between the soft and hard X-ray bands, which is also confirmed in the QPO phase-resolved spectral analysis. Finally, we discuss the indications of current models including a spotted accretion disk, diskoseismology, and oscillation of shock, according to the observed time-frequency and spectral behaviors.

description: Spatially periodic modulation of the intersite coupling in two-dimensional (2D) nonlinear lattices modifies the eigenvalue spectrum by opening mini-gaps in it. This work aims to build stable localized modes in the new bandgaps. Numerical analysis shows that single-peak and composite two- and four-peak discrete static solitons and breathers emerge as such modes in certain parameter areas inside the mini-gaps of the 2D superlattice induced by the periodic modulation of the intersite coupling along both directions.The single-peak solitons and four-peak discrete solitons are stable in a part of their existence domain, while unstable stationary states (in particular, two-soliton complexes) may readily transform into robust localized breathers.

description: A procura de espaços naturais para o desenvolvimento de actividades turísticas tem vindo a crescer bastante nas últimas décadas. Portugal apresenta bastantes recursos de qualidade para o desenvolvimento destas actividades. Em 90 000 mil quilómetros quadrados, 22% do território português é ocupado por áreas protegidas. Um terço do país (3,3 milhões de hectares) é constituído por floresta e existem inúmeros espaços agrícolas. No entanto, para além de ser necessário uma eficiente gestão dos espaços naturais também se torna pertinente conhecer os gostos e a percepção da paisagem por parte dos seus vistantes. Neste artigo apresentamos um estudo, de âmbito exploratório, onde se comparam pessoas que procuram actividades na natureza (pedestrianistas, tanto de origem doméstica como internacional) com pessoas que não apresentam o hábito de desfrutar a natureza para fins de lazer e turismo, para verificar quais as respectivas preferências e percepções face à natureza. Verificou-se que, geralmente, os inquiridos preferiam ambientes naturais que apresentem a presença do homem e paisagens que possuam elementos aquáticos, embora haja diferenças entre os grupos analisados. Estes resultados são bastantes pertinentes para a promoção e o desenvolvimento de actividades em espaço natural direccionadas para segmentos de mercados específicos.

description: Elsewhere I have told the history of Speculative Realism, and will not repeat it here.1 Though some prefer the lower-case phrase “speculative realism,” I deliberately use capital letters, since Speculative Realism is a proper name. It originally referred to an assembly of four philosophers for an April 2007 workshop in London: Ray Brassier, Iain Hamilton Grant, Quentin Meillassoux, and the author of this article. So much for the history of the movement.Any discussion of Speculative Realism needs to begin by avoiding the intermittent and pointless debate over whether Speculative Realism “really exists.” This question comes five years too late to be meaningful, and generally takes the form of a put-down rather than a bona fide question. Speculative Realism is now the topic of a thriving book series at a major university press, and the subject of at least one forthcoming monograph.2 It is embedded in the editorial policy of several philosophy journals. It has become a terme d’art in architecture, archae-ology, geography, the visual arts, and even history. It has crossed national boundaries with ease, and is surely the central theme of discussion in the growing continental philosophy blogosphere. Speculative Re-alism is the topic of several postdoctoral fellowships offered in the United States this year. It has been the subject of semester-long classes at universities as well as graduate theses in Paris. Though there are still tough tests ahead concerning the breadth and durability of Speculative Realism, it has long since passed the “existence” test to a far greater degree than most of its critics.

description: The focus of this research is to design a sensor data aggregation system and centralized sensor-driven trajectory planning algorithm for fixed-wing aircraft to optimally assist atmospheric simulators in mapping the local environment in real-time. The proposed application of this work is to be used in the event of a hazardous contaminant leak into the atmosphere as a fleet of sensing unmanned aerial vehicles (UAVs) could provide valuable information for evacuation measures. The data aggregation system was designed using a state-of-the-art networking protocol and radio with DigiMesh and a process/data management system in the ROS2 DDS. This system was tested to consistently operate within the latencies and distances tolerated for the project while being highly extensible to sensor configurations. The problem of creating optimal trajectory planning for exploration has been modelled accurately using partially-observable Markov decision processes (POMDP). Deep Reinforcement learning (DRL) is commonly applied to approximate optimal solutions within a POMDP as it can be analytically intractable for complex state spaces. This research produces a POMDP that describes this exploration problem and applies the state-of-the-art soft actor-critic (SAC) reinforcement learning algorithm to create a policy that produces near-
optimal trajectories within this new POMDP. A subset of the spatially relevant input
is used instead of complete state during training and a turn-taking sequential planner is designed for using multiple UAVs to help mitigate scalability problems that come with multi-UAV coordination. The learned policy from SAC can outperform a greedy and fixed trajectory on 1, 2, and 3 UAVs by a 30% margin on average. The turn-taking strategy provides small, but repeatable scaling benefits while the windowed input results in a 50%-60% increase in reward versus trained networks without windowed input. The proposed planning algorithm is effective in dynamic map exploration and has the potential to increase UAV effectiveness in atmospheric contaminant leak monitoring as it is expanded to be integrated on real-world UAVs.

title: Heritage policy landscapes of Nunatsiavut: approaching the development of historic resource management policy and law in Northern Labrador
Creators: name: Brake, Jamie E. S.

description: As a result of the Labrador Inuit Land Claims Agreement (being schedule to SNL 2004, c L-3.1) and the Nunatsiavut Government Organization Order (NGSL-2019-07) the Nunatsiavut Government (NG) has the power to develop and implement heritage policy and law. An approach to the development of recommendations for heritage policy and law in the region involving critical use of the Nunatsiavut Government’s policy cycle and public engagement is outlined in this dissertation. The research presented here was conducted through the lens of landscape archaeology which can accommodate multiple perspectives, and which can help bridge theoretical and ontological divides. Relevant discussions that took place during annual regional heritage forums from 2010-2018, and during three public engagement tours on heritage that took place between 2017 and 2019 were thematically reviewed using qualitative data analysis software. The results were then compared to the results of a review of international heritage agreements and Canadian provincial and territorial heritage laws. This allowed for the development of recommendations for both legislative and non-legislative policy measures that the NG can consider as it works towards passing its own heritage law, and as it continues to develop related policy in accordance with the Agreement, and the NG Organization Order. The idea that policy work aimed at effectively managing historic resources has the potential to create societal opportunities beyond the heritage domain was also explored.

description: Constituindo-se como uma das formas de turismo mais remota, o Turismo termal associa-se hoje a uma abrangência conceptual que ultrapassa o termalismo clássico o que é fundamental para a consolidação de projectos turísticos estruturantes, atractivos e sustentáveis, em áreas normalmente debilitadas no que diz respeito ao desenvolvimento económico. Neste sentido, analisar os contornos dos contextos de mudança que caracterizam o novo paradigma do termalismo em Portugal, e que parecem querer sobressair na sua imagem actual, constituiu a matriz orientadora deste artigo. Assim sendo, foi com base num estudo empírico sustentado por um corpo teórico prévio e no exemplo de excelência do caso alemão, bem como das possíveis adaptações de medidas e de políticas à situação lusa, que se procedeu a um estudo qualitativo e quantitativo da oferta termal portuguesa, procurando evidenciar a(s) sensibilidade(s) da oferta termal, na sua globalidade, e o posicionamento da mesma face ao eclodir dum novo paradigma – o da afirmação de destinos de interior. Os resultados das análises permitiram concluir, que apesar da resistência de alguns obstáculos actuais, os responsáveis pela revitalização termal reconhecem a inevitável articulação e complementaridade entre o termalismo curativo, preventivo e lúdico e a sua complementaridade regional/local. Neste contexto, tornou-se evidente que o reposicionamento dos destinos turísticos termais em Portugal baseado numa maior agressividade e originalidade em termos de marketing, consubstanciado na implementação de um modelo inovador e qualitativo, constitui uma necessidade e um desafio ao turismo português através do produto “Saúde e Bem-estar” bem evidenciado no Plano Estratégico Nacional de Turismo – PENT.

description: “Mega-events” describe happenings of international importance and high profile which have a major impact on the image of the host city. These events supply prestige to the host cities, and afford a profile related with the welcomed activities, and a important tourism potential. If mega events are of a sufficiently high quality then people will be prepared to travel some distance to attend. The “European Culture Capital” (ECC) mega event was created with the main objectives of bringing close together the people of the EU member states through cultural expression, and to give the EU and its cities an attractive image. Nowadays is a powerful tool to attract cultural tourists, promote urban and economic renewal and development in the cities. In this paper we will analyse the importance of “ECC” event to cultural tourism development,cultural publics enlargement, city’s equipments renewal, residents pride generation and “local” creative industries enhancement. Through “Porto 2001” event and its realizations, a critical discussion will be developed. Several short and long run will be identified, as well as implications in terms of city’s image. In this case-study, we will also verify the aims’ heterogeneity that’s present in this events development, which not permeates an exclusive “tourism analysis”.

description: UV ice photodesorption is an important non-thermal desorption pathway in many interstellar environments that has been invoked to explain observations of cold molecules in disks, clouds and cloud cores. Systematic laboratory studies of the photodesorption rates, between 7 and 14 eV, from CO:N2 binary ices, have been performed at the DESIRS vacuum UV beamline of the synchrotron facility SOLEIL. The photodesorption spectral analysis demonstrates that the photodesorption process is indirect, i.e. the desorption is induced by a photon absorption in sub-surface molecular layers, while only surface molecules are actually desorbing. The photodesorption spectra of CO and N2 in binary ices therefore depend on the absorption spectra of the dominant species in the subsurface ice layer, which implies that the photodesorption efficiency and energy dependence are dramatically different for mixed and layered ices compared to pure ices. In particular, a thin (1-2 ML) N2 ice layer on top of CO will effectively quench CO photodesorption, while enhancing N2 photodesorption by a factors of a few (compared to the pure ices) when the ice is exposed to a typical dark cloud UV field, which may help to explain the different distributions of CO and N2H+ in molecular cloud cores. This indirect photodesorption mechanism may also explain observations of small amounts of complex organics in cold interstellar environments.
