Tourism and the Sustainable Development Goals in Southeast Asia
Creators: name: Trupp, Alexander

Year: 2020

description: The Sustainable Development Goals (SDGs), a set of 17 goals adopted in 2015, are aimed at reconciling economic, social, and ecological progress at a global level – ensuring a sustainable future for developed and developing countries alike. Tourism in Southeast Asia is particularly thought to make an important contribution – given its substantial economic role – to the SDGs. While the United Nations initially only linked three SDGs to tourism, it bears often underused potential to contribute to the entire set of goals. Yet, the relationship between tourism and sustainable development is regarded as ambiguous – an industry strongly characterized by an overdependence on international tourists and foreign investment, showing a patchy track record of negative impacts and conflicts. In addition, in times of COVID-19, tourism has become a dormant industry, leaving behind substantial economic gaps, particularly in Southeast Asia. With regards to the SDGs, little research exists to date that investigates whether and how tourism can contribute to reaching the goals’ targets to achieve a more sustainable development. This article thus outlines the current situation for tourism for development in Southeast Asia, and discusses the links between tourism and the SDGs, particularly at a time when the region – and theindustry at large – have been strongly impacted.

description: Language and tourism are essentially interconnected by the cross-border movement of tourists and the resulting encounters of people who often speak different languages. These relationships, however, have not been explored very much in the context of community- based tourism (CBT), a kind of tourism that has the potential to enhance communities’ socioeconomic growth, language skills, and cultural heritage. This study explores local communities’ perceived English language needs and challenges for tourism purposes in Thailand’s second-tier provinces of Chiang Rai and Buriram. Informed by fieldwork observations, semi-structured, and focus-group interviews, the findings reveal four key issues: i) the limitations of host-guest interaction and communication, ii) dependency on tour guides, iii) communities’ current communicative English needs, and iv) language users’ sociocultural and linguistic identities. In the cross-cultural tourism encounter, English was needed by the communities despite its limited use by CBT leaders and mem- bers. Cultural identities of the communities and individual speakers were constructed by tour guides whose interpretations of cultural meanings could have been lost in trans- lation. Despite the hegemonic lingua franca status of English, multilingual competence among CBT professionals should be promoted to facilitate community communication and more independence from external translators and cultural brokers. Driven by Thai- land’s current economic development model, information and communication technol- ogy (ICT) could be used to help meet Sustainable Development Goals (SDGs) 4 (Quality Education) and 8 (Decent Work and Economic Growth) by promoting lifelong learning opportunities and socioeconomic development for remote tourism destinations.

description: Justification of knowledge and the method of explanation are questions central to the philosophy of science. Well known problems occur if the attempt is made to develop a methodologically unified approach that encompasses both physics and history. These problems arise from the differentiation between explanation and understanding in science. In this paper, I introduce a concept of explanation in historical scholarship in order to address these problems. To do so, I outline an understanding of explanations based on the concept of simulating a certain historical space of events (Ereignisraum) as well as the opportunities, historical actors could have found within that space to act. Therefore, I argue that the way historical knowledge is produced can be understood as a closed circle of simulations.

1973: Chilean academics in the Emergency

description: Following the military coup d’état on 11 September 1973, the Chilean academic field went through a significant process of reconfiguration as thousands of students, teachers and researchers were excluded, numerous centres of study were closed, and areas of research and careers were terminated. In response, expressions of solidarity multiplied around the world. In the United Kingdom, British academics – mainly those involved in Latin American studies and development studies – were the first to get organized under the name Academics for Chile, in order to support their Chilean peers affected by the military coup. These endeavours were channelled through a programme of scholarships managed by the World University Service, United Kingdom (WUS UK). The paper focuses on that Scholarship Programme for Chilean Refugees. This programme is described as an experience born where British academia and the political world intersected. I propose a trans-national view of the phenomenon of exile that highlights particular nexuses – academic links, and political and social networks – between different national communities.

description: A novel Parallelised Bayesian Inference of the Multispecies Coalescent with new MCMC proposals has been implemented in the open-source BEAST 2 platform as the StarBeast3 package. This new approach avoids biases, such as being an inconsistent estimator of the tree topology. Furthermore, it explores the state space much more efficiently, allowing the handle of data sets one and a half orders of magnitude larger than StarBeast2 and more than two orders faster than *BEAST. Our goal was to establish the correct implementation of StarBeast3 by testing different numbers of taxa and genes. We performed well calibration studies by simulating alignments using parameters directly sampled from the prior distribution, and then we inferred the posterior estimates of these parameters using StarBeast3. We evaluated a strict and relaxed clock model, across varying tree sizes ( 4 species: 12 taxa; 16 species: 48 taxa), and multiple genes (10, 50, 100, and 200). With 100 independent runs, we estimated the coverage of the true value by the 95% highest probability density (HPD) estimates for various parameters in the model and its newly developed efficient MCMC operators. Our results show all coverage observed is in the expected range, from 90 to 99 inclusive, suggesting the correct implementation of StarBeast3 for all experiments performed. Furthermore, these experiments evidence that startbeast3 is suitable for multispecies coalescent inference on large datasets (100+ genes).
Are there field-free gaps near tau=1 in sunspot penumbrae?

description: The vertical stratification of the magnetic field strength in sunspot penumbrae is investigated by means of spectropolarimetric observations at high spatial resolution from the Hinode spacecraft. Assuming that the magnetic field changes linearly with optical depth we find that, in those regions where the magnetic field is more inclined and the Evershed flow is strongest (penumbral intraspines), the magnetic field can either increase or decrease with depth. Allowing more degrees of freedom to the magnetic field stratification reveals that the magnetic field initially decreases from \logτ_5 = -3 until \logτ_5 \simeq -1.0, but increases again below that. The presence of strong magnetic fields near the continuum is at odds with the existence of regions void of magnetic fields at, or right below, the τ_5=1 level in the penumbra. However, they are compatible with the presence of a horizontal flux-tube-like field embedded in a magnetic atmosphere.

Publisher: name: IMT Alti Studi Lucca
Year: 2014
Subjects: HB Economic Theory

description: The present work introduces the main regulatory issues faced nowadays in EU by policy-makers in the design of the electricity and natural gas markets.
The dissertation consists of the following parts: Chapter 2 introduces the new challenges that are currently engaging the European markets, under the perspective
of the stronger integration expected in the next years. The coordination of the investments in new facilities and the rules governing their access, the increasing
need of flexible resources as well as the integration of spot and forward markets will be some of the themes examined in this first section. Chapter 3 focuses on the
regulatory interventions aimed at increase the flexibility of the storage services in the Italian gas market. A first part of the work is devoted to describe the
storage technologies, the services they provide and their current regulatory framework. The rest of the chapter discusses the main issues related to the elicitation
of flexible resources and the attraction of investments in new storage infrastructures. Finally, chapter 4 builds a model of competition to study the bidding strategies
of the power generation firms in a dayahead electricity market based on zonal pricing. The analysis shows the role that investments in the transmission network
may have on the degree of market competition, final prices and social welfare.

description: The adiabatic quantum evolution of the Lipkin-Meshkov-Glick (LMG) model across its quantum critical point is studied. The dynamics is realized by linearly switching the transverse field from an initial large value towards zero and considering different transition rates. We concentrate our attention on the residual energy after the quench in order to estimate the level of diabaticity of the evolution. We discuss a Landau-Zener approximation of the finite size LMG model, that is successful in reproducing the behavior of the residual energy as function of the transition rate in the most part of the regimes considered. We also support our description through the analysis of the entanglement entropy of the evolved state. The system proposed is a paradigm of infinite-range interaction or high-dimensional models.

description: Starting in the late nineteenth century, German nationalist organizations in Imperial Austria sought to anchor their communities in specific territories. Since the Imperial Austrian state did not recognize territorial nations within its boundaries, nationalist activists tried to realize their nations in specific places by promoting a sense of commonality that would link all members of the nation throughout the Empire. Some nationalists saw tourism and travel writing as strategic activities that could specifically strengthen both a sense of national belonging and a sense of national space. Increasingly, nationalists exhorted Germans in Austria to use their leisure and travel opportunities to learn about their brethren in other parts of the Empire. After the First World War, the destruction of Austria-Hungary and the prevention of an Anschluss between Germany and the Austrian Republic, German nationalists in Austria used tourism and travel accounts as a means to remind their readers of the national territories that had been lost and of the German communities that now suffered under foreign rule. In particular this article examines the efforts of the German nationalist organization Südmark in Austria to use tourism and travel accounts as a way to give new meaning to older concepts of cultural borderlands in the popular imagination. By emphasizing the commonalities of diverse German communities across Central Europe, nationalist activists sought to portray the German-speaking communities of the former Habsburg Monarchy as parts of a larger nation whose reference point was now Germany.

description: Reciprocal movement cannot be used for locomotion at low-Reynolds number in an infinite fluid or near a rigid surface. Here we show that this limitation is relaxed for a body performing reciprocal motions near a deformable interface. Using physical arguments and scaling relationships, we show that the nonlinearities arising from reciprocal flow-induced interfacial deformation rectify the periodic motion of the swimmer, leading to locomotion. Such a strategy can be used to move toward, away from, and parallel to any deformable interface as long as the length scales involved are smaller than intrinsic scales, which we identify. A macro-scale experiment of flapping motion near a free surface illustrates this new result.

The Experience of Retirement in Britain, Past and Present
Creators: name: Thane, Pat
Publisher: name: Austrian Journal of Historical Studies
Year: 2011

description: Until quite recently in Britain retirement was possible only for the better-off. Most poorer people, until the mid-twentieth century, worked for survival until they dropped. The rich could always retire when they chose, most others only when required by their occupation or pension scheme. In Britain, externally imposed retirement, with a pension, began in the 19th century in the public service, then spread to cover the whole working population after World War 2, often as a management strategy supposed to improve efficiency. When male manual workers were first obliged to retire they found the sudden transition in their lives an unwelcome shock. Women found it easier because domestic work continued and they generally had closer family and friendship networks to sustain them. Later generations, by the 1960s and 70s learned to look forward to a period of leisure in later life though for many, especially women, it was a life of poverty. But older people were healthier than in the past and often active in voluntary work, caring for grandchildren and others. Retirement ages fell in 1980s and 1990s, then rose again under pressure from government and employers concerned about declining numbers of younger workers and the costs of pensions to growing numbers of older people.

description: Hunting played a prominent role in the life of the political elite of the Kádár era; besides recreation, it also provided an excellent opportunity for relationship building. In our study we set out to identify certain features of power dynamics, as well as structural characteristics of the system based on the trophy presentation lists of one of the most remarkable hunting associations of the era, Egyetértés, founded exclusively for the members of the political elite. The results confirmed our initial hypotheses suggesting that a reflection of the slow decomposition of the system could be observed through the hunting customs. Over time the leading political members of the hunting association Egyetértés hunted less and less together, with the network of joint hunting collaterally losing its density, showing a diminished clustering coefficient and sabotage tolerance. Signs of the decay of the system were clearly reflected by hunting customs and the hunting network. Nevertheless, the data demonstrate more than that: they mark the actors’ informal position within the power structure, while at the same time outlining the path of power dynamics of the given figures.

Gateways to Modernity: Niccolo Machiavelli and Max Weber
Creators: name: Eliaeson, Sven
Publisher: name: Austrian Journal of Historical Studies
Year: 2012

description: Heinz Steinert’s recent work on Max Weber’s Calvinist thesis is challenging and thought provoking, but hardly convincing. There are reasons to believe that Weber’s views on the birth of Modernity will survive also this assault. Steinert, however, brings in a methodological dimension about how to interpret classics in the proper pursuit of intellectual history, in the search for a pragmatic balance between formative experiences, context and tradition. Niccolo Machiavelli and Max Weber are both manifestations of Modernity, in different epochs. There are amazingly many affinities between them. They both need to be understood and interpreted in context, yet being significant in a long line in intellectual history, characterized by anti-metaphysics, calculability and demise of natural law. Weber’s value-philosophy makes ready soil for rationalization of value-hierarchies, further developed by Gunnar Myrdal in his social engineering. Machiavelli’s amazing modernity is an embryonic early bird to instrumental means-end rational policy analysis and part of a tradition with Thomas Hobbes, Samuel Pufendorf and Jeremy Bentham as important way-stations. This tradition has many opponents. Steinert is right in most of his criticism of Weber’s analysis but has not much new to add, except a more clear emphasis on the Bismarckian Kulturkampf against cosmopolitan forces, such as Marxism and Catholicism, as main elements in Weber’s context.

Conceptualizing Work/Employment in India

description: This paper examines chakri as a distinct category of work in colonial Bengal. It traces the emergence of chakri in Bengal’s encounters with colonialism, and the subsequent association of the category with ”English education” and the bhadralok (literally, ”respec- table ones”). Chakri was and continues to be a referent of white-collar jobs in Bengal. In addition, it was crucial to consolidating respectability, as the bhadralok distinguished themselves from those who engaged in manual or menial labour (e.g., peasants, domestic workers etc.). However, a closer look at the terms chakure (employee) and chakor (servant) reveals differing connotations. Characteristics embedded in the notion of chakor – service, servitude and loyalty – noticeably blurred the lines that divided respectable work from manual-menial labour. Yet divisions between these two were maintained, even as the undertones of servant varied morally within the socioeconomic categories of chakure and chakor. At the same time, this study extends beyond immediate concerns of livelihood in order to encompass broader yet interrelated realms of citizenship and nation building.

description: The origin of supermassive black holes (with $\gtrsim\!10^9\,M_{\odot}$) in the early universe (redshift $z \sim 7$) remains poorly understood. Gravitational collapse of a massive primordial gas cloud is a promising initial process, but theoretical studies have difficulty growing the black hole fast enough. We focus on the magnetic effects on star formation that occurs in an atomic-cooling gas cloud. Using a set of three-dimensional magnetohydrodynamic (MHD) simulations, we investigate the star formation process in the magnetized atomic-cooling gas cloud with different initial magnetic field strengths. Our simulations show that the primordial magnetic seed field can be quickly amplified during the early accretion phase after the first protostar formation. The strong magnetic field efficiently extracts angular momentum from accreting gas and increases the accretion rate, which results in the high fragmentation rate in the gravitationally unstable disk region. On the other hand, the coalescence rate of fragments is also enhanced by the angular momentum transfer due to the magnetic effects. Almost all the fragments coalesce to the primary star, so the mass growth rate of the massive star increases due to the magnetic effects. We conclude that the magnetic effects support the direct collapse scenario of supermassive star formation.

description: Here we review scanning tunneling microscopy research on the surface determination for various types of kagome materials, including 11-type (CoSn, FeSn, FeGe), 32-type (Fe3Sn2), 13-type (Mn3Sn), 135-type (AV3Sb5, A = K, Rb, Cs), 166-type (TbMn6Sn6, YMn6Sn6 and ScV6Sn6), and 322-type (Co3Sn2S2 and Ni3In2Se2). We first demonstrate that the measured step height between different surfaces typically deviates from the expected value of +-0.4~0.8A, which is owing to the tunneling convolution effect with electronic states and becomes a serious issue for Co3Sn2S2 where the expected Sn-S interlayer distance is 0.6A. Hence, we put forward a general methodology for surface determination as atomic step geometry imaging, which is fundamental but also experimentally challenging to locate the step and to image with atomic precision. We discuss how this method can be used to resolve the surface termination puzzle in Co3Sn2S2. This method provides a natural explanation for the existence of adatoms and vacancies, and beyond using unknown impurity states, we propose and use designer layer-selective substitutional chemical markers to confirm the validity of this method. Finally, we apply this method to determine the surface of a new kagome material Ni3In2Se2, as a cousin of Co3Sn2S2, and we image the underlying kagome geometry on the determined Se surface above the kagome layer, which directly visualizes the p-d hybridization physics. We emphasize that this general method does not rely on theory, but the determined surface identity can provide guidelines for first-principles calculations with adjustable parameters on the surface-dependent local density of states and quasi-particle interference patterns.
A Stochastic Model for Block Segmentation of Images Based on the Quadtree and the Bayes Code for It

Year: 2021

description: In information theory, lossless compression of general data is based on an explicit assumption of a stochastic generative model on target data. However, in lossless image compression, the researchers have mainly focused on the coding procedure that outputs the coded sequence from the input image, and the assumption of the stochastic generative model is implicit. In these studies, there is a difficulty in confirming the information-theoretical optimality of the coding procedure to the stochastic generative model. Hence, in this paper, we propose a novel stochastic generative model of images by redefining the implicit stochastic generative model in a previous coding procedure. That is based on the quadtree so that our model effectively represents the variable block size segmentation of images. Then, we construct the Bayes code optimal for the proposed stochastic generative model. In general, the computational cost to calculate the posterior distribution required in the Bayes code increases exponentially for the image size. However, we introduce an efficient algorithm to calculate it in the polynomial order of the image size without loss of the optimality. Some experiments are performed to confirm the flexibility of the proposed stochastic model and the efficiency of the introduced algorithm.

WIMPs are taken as neutralinos in the context of the minimal super-symmetric extension of the standard model (MSSM). The dependence of the results with the adopted MSSM parameters is discussed.

description: Using the cut-and-paste procedure, we construct static and dynamic plane symmetric wormholes by surgically grafting together two spacetimes of plane symmetric vacuum solutions with a negative cosmological constant. These plane symmetric wormholes may be viewed as domain walls connecting different universes, having planar topology, and upon compactification of one or two coordinates, cylindrical topology or toroidal topology, respectively. A stability analysis is carried out for the dynamic case by taking into account specific equations of state, and a linearized stability analysis around static solutions is also explored. It is found that thin shell wormholes made of a dark energy fluid or of a cosmological constant fluid are stable, while thin shell wormholes made of phantom energy are unstable.

description: Actively participating in body movement such as dance, sports, and fitness activities is challenging for people who are blind or have low vision (BLV). Teachers primarily rely on verbal instructions and physical demonstrations with limited accessibility. Recent work shows that technology can support body movement education for BLV people. However, there is limited involvement with the BLV community and their teachers to understand their needs. By conducting a series of two surveys, 23 interviews and four focus groups, we gather the voices and perspectives of BLV people and their teachers. This provides a rich understanding of the challenges of body movement education. We identify ten major themes, four key design challenges, and propose potential solutions. We encourage the assistive technologies community to co-design potential solutions to these identified design challenges promoting the quality of life of BLV people and supporting the teachers in the provision of inclusive education.

description: We study the transport coefficients of Quark-Gluon-Plasma in finite temperature and finite baryon density. We use AdS/QCD of charged AdS black hole background with bulk-filling branes identifying the U(1) charge as the baryon number. We calculate the diffusion constant, the shear viscosity and the thermal conductivity to plot their density and temperature dependences. Hydrodynamic relations between those are shown to hold exactly. The diffusion constant and the shear viscosity are decreasing as a function of density for fixed total energy. For fixed temperature, the fluid becomes less diffusible and more viscous for larger baryon density.

Static dielectric screening and exchange in the layered electron gas
Creators: name: Glaus, Ulrich Walter
Publisher: name: University of British Columbia
Year: 2010

description: The static screening properties of the layered electron gas are studied using a very idealized model. Exchange and correlation have been included to first order. A generalized susceptibility is obtained, which is consistent with the results of other authors. The induced charge density in linear response to a positive point charge in one of the planes predicted by the new susceptibility exhibits slowly decaying long range oscillations. Finally, a formula for the screened potential of external charges between layers is given, which might be of some use in an application to intercalation compounds.

description: To test the validity of replacing a composite fermion by an elementary fermion, we here calculate the transition rate from a state made of one free electron and one trion to a similar electron-trion pair, through the time evolution of such a pair induced by Coulomb interaction between elementary fermions. To do it in a convenient way, we describe the trion as one electron interacting with one exciton, and we use the tools we have developed in the new composite-exciton many-body theory. The trion-electron scattering contains a direct channel in which ``in'' and ``out'' trions are made with the same fermions, and an exchange channel in which the ``in'' free electron becomes one of the ``out'' trion components. As expected, momenta are conserved in these two channels. The direct scattering is found to read as the bare Coulomb potential between elementary particles multiplied by a form factor which depends on the ``in'' and ``out'' trion relative motion indices $η$ and $η'$, this factor reducing to $δ_{ηη'}$ in the zero momentum transfer limit: In this direct channel, the trion at large distance reacts as an elementary particle, its composite nature showing up for large momentum transfer. On the contrary, the fact that the trion is not elementary does affect the exchange channel for all momentum transfers. We thus conclude that a 3-component fermion behaves as an elementary fermion for direct processes in the small momentum transfer limit only.

description: Clouds seem like an every-day experience. But -- do we know how clouds form on brown dwarfs and extra-solar planets? How do they look like? Can we see them? What are they composed of? Cloud formation is an old-fashioned but still outstanding problem for the Earth atmosphere, and it has turned into a challenge for the modelling of brown dwarf and exo-planetary atmospheres. Cloud formation imposes strong feedbacks on the atmospheric structure, not only due to the clouds own opacity, but also due to the depletion of the gas phase, possibly leaving behind a dynamic and still supersaturated atmosphere. I summarise the different approaches taken to model cloud formation in substellar atmospheres and workout their differences. Focusing on the phase-non-equilibrium approach to cloud formation, I demonstrate the inside we gain from detailed micro-physical modelling on for instance the material composition and grain size distribution inside the cloud layer on a Brown Dwarf atmosphere. A comparison study on four different cloud approaches in Brown Dwarf atmosphere simulations demonstrates possible uncertainties in interpretation of observational data.

description: We have developed a new method to improve the transit detection of Earth-sized planets in front of solar-like stars by fitting stellar microvariability by means of a spot model. A large Monte Carlo numerical experiment has been designed to test the performance of our approach in comparison with other variability filters and fitting techniques for stars of different magnitudes and planets of different radius and orbital period, as observed by the space missions CoRoT and Kepler. Here we report on the results of this experiment.

description: User trajectory data is becoming increasingly accessible due to the prevalence of GPS-equipped devices such as smartphones. Many existing studies focus on querying trajectories that are similar to each other in their entirety. We observe that trajectories partially similar to each other contain useful information about users' travel patterns which should not be ignored. Such partially similar trajectories are critical in applications such as epidemic contact tracing. We thus propose to query trajectories that are within a given distance range from each other for a given period of time. We formulate this problem as a sub-trajectory similarity join query named as the STS-Join. We further propose a distributed index structure and a query algorithm for STS-Join, where users retain their raw location data and only send obfuscated trajectories to a server for query processing. This helps preserve user location privacy which is vital when dealing with such data. Theoretical analysis and experiments on real data confirm the effectiveness and the efficiency of our proposed index structure and query algorithm.

description: We present here the first results of a spectropolarimetric analysis of a small sample (about 20) of active stars ranging from spectral type M0 to M8, which are either fully-convective or possess a very small radiative core. This study aims at providing new constraints on dynamo processes in fully-convective stars. Results for stars with spectral types M0-M4 -- i.e. with masses above or just below the full convection threshold (about 0.35Msun) -- are presented. Tomographic imaging techniques allow us to reconstruct the surface magnetic topologies from the rotationally modulated time-series of circularly polarised profiles. We find strong differences between partly and fully convective stars concerning magnetic field topology and characteristic scales, and differential rotation. Our results suggest that magnetic field generation in fully convective stars relies on different dynamo processes than those acting in the Sun and other partly convective stars, in agreement with theoretical expectations.

description: In E-commerce, vouchers are important marketing tools to enhance users' engagement and boost sales and revenue. The likelihood that a user redeems a voucher is a key factor in voucher distribution decision. User-item Click-Through-Rate (CTR) models are often applied to predict the user-voucher redemption rate. However, the voucher scenario involves more complicated relations among users, items and vouchers. The users' historical behavior in a voucher collection activity reflects users' voucher usage patterns, which is nevertheless overlooked by the CTR-based solutions. In this paper, we propose a Deep Multi-behavior Graph Networks (DMBGN) to shed light on this field for the voucher redemption rate prediction. The complex structural user-voucher-item relationships are captured by a User-Behavior Voucher Graph (UVG). User behavior happening both before and after voucher collection is taken into consideration, and a high-level representation is extracted by Higher-order Graph Neural Networks. On top of a sequence of UVGs, an attention network is built which can help to learn users' long-term voucher redemption preference. Extensive experiments on three large-scale production datasets demonstrate the proposed DMBGN model is effective, with 10% to 16% relative AUC improvement over Deep Neural Networks (DNN), and 2% to 4% AUC improvement over Deep Interest Network (DIN). Source code and a sample dataset are made publicly available to facilitate future research.
