description: Coastal coral reefs, especially in the Florida Keys, are declining at a disturbing rate. Marine ecologists and reef scientists have emphasized the importance of establishing nonmarket values of coral reefs to assess the cost effectiveness of coral reef management and remediation programs. The purpose of this paper is to develop a travel cost - contingent valuation model of demand for trips to the Florida Keys focusing on willingness to pay (WTP) to preserve the current water quality and health of the coral reefs. The stated and revealed preference models allow the marginal valuation of recreationists to adjust depending on current and planned trip commitments in valuing nonmarginal policy changes in recreational opportunities. The integrated model incorporates key factors for establishing baseline amenity values for tourist dive sites, including perceptions of reef quality and dive conditions, the role of substitute sites, and the quality and availability of tourist facilities and recreation opportunities. The travel cost and WTP model differ in identifying critical variables and provide insight into the adjustment of trip decisions across alternative destination sites and the valuation of trips. In contrast to the travel cost model, a measure of the availability of substitute sites and total recreation activities does not have a significant impact on WTP valuations reported by snorkelers. Snorkelers engage in a relatively focused set of activities, suggesting that these recreationists may not shift expenditures to other sites or other recreation activities in the Florida Keys when confronted with increased access costs for the snorkeling experience.

description: Fixed search costs associated with locating and purchasing pecans invalidate the Tobit model. Factors such as perceived quality, ease of purchase, and familiarity with marketing outlets influence the fixed costs of pecan purchases. These factors have differing impacts on the probability of purchasing and the amount purchased based on the Heckman model. Failure to apply self-selectivity corrections produces misleading assessments of key variables influencing pecan purchases. (Missing tables 1,2,3)

description: Reinforcement learning is a powerful framework for robots to acquire skills from experience, but often requires a substantial amount of online data collection. As a result, it is difficult to collect sufficiently diverse experiences that are needed for robots to generalize broadly. Videos of humans, on the other hand, are a readily available source of broad and interesting experiences. In this paper, we consider the question: can we perform reinforcement learning directly on experience collected by humans? This problem is particularly difficult, as such videos are not annotated with actions and exhibit substantial visual domain shift relative to the robot's embodiment. To address these challenges, we propose a framework for reinforcement learning with videos (RLV). RLV learns a policy and value function using experience collected by humans in combination with data collected by robots. In our experiments, we find that RLV is able to leverage such videos to learn challenging vision-based skills with less than half as many samples as RL methods that learn from scratch.

description: We present HST/ACS images and color-magnitude diagrams for 25 nearby galaxies with radial velocities V_LG < 500 km/s. Distances are determined based on the luminosities of stars at the tip of the red giant branch that range from 2 Mpc to 12 Mpc. Two of the galaxies, NGC 4163 and IC 4662, are found to be the nearest known representatives of blue compact dwarf (BCD) objects. Using high-quality data on distances and radial velocities of 110 nearby field galaxies, we derive their mean Hubble ratio to be 68 km/(s Mpc) with standard deviation of 15 km/(s Mpc). Peculiar velocities of most of the galaxies, V_pec = V_LG - 68 D, follow a Gaussian distribution with sigma_v = 63 km/s, but with a tail towards high negative values. Our data displays the known correlation between peculiar velocity and galaxy elevation above the Local Supercluster plane. The small observed fraction of galaxies with high peculiar velocities, V_pec < -500 km/s, may be understood as objects associated with nearby groups (Coma I, Eridanus) outside the Local volume.

description: The miltifractal properties and scaling behaviour of the exchange rate variations of the Iranian rial against the US dollar from a daily perspective is numerically investigated. For this purpose the multifractal detrended fluctuation analysis (MF-DFA) is used. Through multifractal analysis, the scaling exponents, generalized Hurst exponents, generalized fractal dimensions and singularity spectrum are derived. Moreover, contribution of two major sources of multifractality, that is, fat-tailed probability distributions and nonlinear temporal correlations are studied.

description: Stochastic frontier analysis is employed for a comparison of value-added and traditional measures of performance. Results indicate value-added measures are not significantly different from traditional measures of performance and thus little if any information is gained by replacing traditional measures with value-added measures. However, value-added measures may be useful to managers for value creation decisions resulting in excess profits.

description: Magnetic skyrmions are topological spin textures holding great potential as nanoscale information carriers. Recently, skyrmions have been predicted in antiferromagnets, with key advantages in terms of stability, size, and dynamical properties over their ferromagnetic analogs. However, their experimental demonstration is still lacking. Here, we show the imprint from ferromagnetic skyrmions into a thin film of an IrMn antiferromagnet, at room temperature and zero external magnetic field, using exchange-bias. Using high-spatial-resolution x-ray magnetic circular dichroism photoemission electron microscopy (XMCD-PEEM), we observed the imprinted spin textures within the IrMn from the XMCD signal of the uncompensated Mn spins at the interface with the ferromagnet. This result opens up a path for logic and memory devices based on skyrmion manipulation in antiferromagnets.

City for sale : planning for urban tourism in Vancouver
Creators: name: Schwartz, Shaugn Colin
Publisher: name: University of British Columbia
Year: 2009

description: Given the increase in tourism demand, this thesis examines how the City of Vancouver is currently planning for urban tourism for downtown Vancouver and identifies some alternative policy approaches adopted by other cities in the Northwest Region. A review of the urban tourism literature provides an overview of various ideas and conceptual frameworks related to urban tourism supply and demand with an emphasis on the relationship between visitor activity and urban planning. This review concludes with the identification of a set of issues that have planning implications for the built, natural, and cultural environments of the urban setting. Having determined that the City of Vancouver does not address tourism activity in the Central Area Plan, selected tourism activity and development issues specific to downtown Vancouver are highlighted to draw attention to the need for planners to plan for urban tourism. Urban tourism policy alternatives were derived from the planning documents and interviews with planners and destination managers from Seattle, Portland and San Francisco. The data was analysed and grouped according to the main urban tourism issues. An interesting progression is noted from minimal tourism land use planning in Seattle to moderate planning in Portland and finally, in San Francisco, thorough explicit and detailed land use planning which recognizes the impacts of tourism on the city. Suggestions for City of Vancouver planners and destination managers are advanced to address the potential adverse impacts of urban tourism. More study is required on how visitors behave in downtown Vancouver to better inform planning policy.

description: Let R be a ring, M a nonzero left R-module, X an infinite set, and E the endomorphism ring of the direct sum of copies of M indexed by X. Given two subrings S and S' of E, we will say that S is equivalent to S' if there exists a finite subset U of E such that the subring generated by S and U is equal to the subring generated by S' and U. We show that if M is simple and X is countable, then the subrings of E that are closed in the function topology and contain the diagonal subring of E (consisting of elements that take each copy of M to itself) fall into exactly two equivalence classes, with respect to the equivalence relation above. We also show that every countable subset of E is contained in a 2-generator subsemigroup of E.

description: Image guidance for minimally invasive interventions is usually performed by acquiring fluoroscopic images using a C-arm system. However, the projective data provide only limited information about the spatial structure and position of interventional tools such as stents, guide wires or coils. In this work we propose a deep learning-based pipeline for real-time tomographic (four-dimensional) interventional guidance at acceptable dose levels. In the first step, interventional tools are extracted from four cone-beam CT projections using a deep convolutional neural network (CNN). These projections are then reconstructed and fed into a second CNN, which maps this highly undersampled reconstruction to a segmentation of the interventional tools. Our pipeline is capable of reconstructing interventional tools from only four x-ray projections without the need for a patient prior with very high accuracy. Therefore, the proposed approach is capable of overcoming the drawbacks of today's interventional guidance and could enable the development of new minimally invasive radiological interventions by providing full spatiotemporal information about the interventional tools.

description: We consider solutions of the one-dimensional equation $-u'' +(Q+ λV) u = 0$ where $Q: \mathbb{R} \to \mathbb{R}$ is locally integrable, $V : \mathbb{R} \to \mathbb{R}$ is integrable with supp$(V) \subset [0,1]$, and $λ\in \mathbb{R}$ is a coupling constant. Given a family of solutions $\{u_λ \}_{λ\in \mathbb{R}}$ which satisfy $u_λ(x) = u_0(x)$ for all $x<0$, we prove that the zeros of $b(λ) := W[u_0, u_λ]$, the Wronskian of $u_0$ and $u_λ$, form a discrete set unless $V \equiv 0$. Setting $Q(x) := -E$, one sees that a particular consequence of this result may be stated as: if the fixed energy scattering experiment $-u'' + λV u = Eu$ gives rise to a reflection coefficient which vanishes on a set of couplings with an accumulation point, then $V \equiv 0$.

description: Large organizations that collect data about populations (like the US Census Bureau) release summary statistics that are used by multiple stakeholders for resource allocation and policy making problems. These organizations are also legally required to protect the privacy of individuals from whom they collect data. Differential Privacy (DP) provides a solution to release useful summary data while preserving privacy. Most DP mechanisms are designed to answer a single set of queries. In reality, there are often multiple stakeholders that use a given data release and have overlapping but not-identical queries. This introduces a novel joint optimization problem in DP where the privacy budget must be shared among different analysts. We initiate study into the problem of DP query answering across multiple analysts. To capture the competing goals and priorities of multiple analysts, we formulate three desiderata that any mechanism should satisfy in this setting -- The Sharing Incentive, Non-Interference, and Adaptivity -- while still optimizing for overall error. We demonstrate how existing DP query answering mechanisms in the multi-analyst settings fail to satisfy at least one of the desiderata. We present novel DP algorithms that provably satisfy all our desiderata and empirically show that they incur low error on realistic tasks.

description: The progress of the studies on the orientation of galaxies in the Local Supercluster (LSC) is reviewed and a summary of recent results is given. Following a brief introduction of the LSC, we describe the results of early studies based on two-dimensional analysis, which were mostly not conclusive. We describe next the three-dimensional analysis, which is used widely today. Difficulties and systematic effects are explained and the importance of selection effects is described. Then, results based on the new method and modern databases are given, which are summarized as follows. When the LSC is seen as a whole, galaxy planes tend to align perpendicular to the LSC plane with lenticulars showing the most pronounced tendency. Projections onto the LSC plane of the spin vectors of Virgo cluster member galaxies, and to some extent, those of the total LSC galaxies, tend to point to the Virgo cluster center. This tendency is more pronounced for lenticulars than for spirals. It is suggested that 'field' galaxies, i.e., those which do not belong to groups with more than three members, may be better objects than other galaxies to probe the information at the early epoch of the LSC formation through the analysis of galaxy orientations. Field lenticulars show a pronounced anisotropic distribution of spin vectors in the sense that they lay their spin vectors parallel to the LSC plane while field spirals show an isotropic spin-vector distribution.

description: Sejak sebelum Indonesia merdeka, diaspora Nusantara yang tinggal di Eropa sudah mempunyai jiwa nasionalisme dan berperan aktif dalam bela negara. Mohammad Hatta, Soetan Sjahrir, dan kawan-kawan adalah contoh diaspora di kalangan mahasiswa di Belanda yang ketika itu memotori organisasi “Perhimpoenan Indonesia (PI)”. Mereka motor transformasi Indische Vereeninging yang awalnya organisasi yang hanya berfungsi social dan informatif menjadi organisasi yang secara eksplisit memperjuangkan kemerdekaan Indonesia dan mempopulerkan kata “Indonesia” sebagai kata pemersatu masyarakat Nusantara. Tidak hanya di Belanda, diaspora Nusantara di negara Eropa lain, seperti Sam Ratulangi, seorang mahasiswa yang belajar di Zürich, juga bertransformasi dari berjiwa kesukuan Minahasa menjadi berjiwa nasionalisme Indonesia. Dan tidak hanya mahasiswa, diaspora yang menetap lama di Eropa pun juga mengambil peran dalam perjuangan menuju kemerdekaan Indonesia, seperti Usman Idris, akademisi di Universitas Hamburg yang lahir di Minangkabau dan Sosrokartono, wartawan asal Jawa yang bekerja di Wina. Webinar kali ini akan mendiskusikan perspektif dan peran diaspora Indonesia di Jerman dari kalangan mahasiswa dan profesional dalam bela negara, setelah 75 tahun Indonesia merdeka atau hampir seabad setelah tokoh-tokoh tersebut mengambil peran mereka di Eropa. Webinar kali ini akan menghadirkan Dr. Ir. Zainal Abidin, praktisi pendidikan dari Indonesia yang memiliki segudang pengalaman dalam pengembangan konsep pendidikan bela negara di tingkat perguruan tinggi. Diaspora professional akan diwakili oleh dr. Prasti Pomarius, seorang dokter di Jerman yang meluangkan waktu senggangnya untuk memperkenalkan budaya Indonesia di Jerman serta terjun ke Indonesia untuk meningkatkan layanan kesehatan di pelosok-pelosok. Mas Mochammad Mirza Ilham Tontowi, seorang mahasiswa di TU Berlin yang juga aktif di kegiatan kemahasiswaan sebagai ketua PCI PMII Jerman, akan menyampaikan perspektifnya tentang bela negara sebagai seorang yang belum pernah mencicipi pendidikan tinggi di Indonesia. Webinar akan menghadirkan Kyai Syaeful Fatah dan Pendeta Favor Bancin untuk meninjau konsep bela negara dari perspektif agama. Akan menarik disimak apakah persepsi diaspora professional dan mahasiswa yang hampir tidak pernah mendapatkan materi pendidikan tinggi bela negara, selaras dengan konsep bela negara yang dikembangkan praktisi pendidikan Indonesia.

description: We calculate the gravitational waves (GWs) induced by the density fluctuations due to inhomogeneous distribution of primordial black holes (PBHs) in the case where PBHs eventually dominate and reheat the universe by Hawking evaporation. The initial PBH density fluctuations are isocurvature in nature. We find that most of the induced GWs are generated right after evaporation, when the universe transits from the PBH dominated era to the radiation dominated era and the curvature perturbation starts to oscillate wildly. The strongest constraint on the amount of the produced GWs comes from the big bang nucleosynthesis (BBN). We improve previous constraints on the PBH fraction and find that it cannot exceed $10^{-3}$. Furthermore, this maximum fraction decreases as the mass increases and reaches $10^{-9}$ for $M_{\rm PBH}\sim 5\times10^8 {\rm g}$, which is the largest mass allowed by the BBN constraint on the reheating temperature. Considering that PBH may cluster above a given clustering scale, we also derive a lower bound on the scale of clustering. Interestingly, the GW spectrum for $M_{\rm PBH}\sim 10^4 -10^8 {\rm g}$ enters the observational window of LIGO and DECIGO and could be tested in the future. Although we focus on the PBH dominated early universe in this paper, our methodology is applicable to any model with early isocurvature perturbation.

description: A big mystery in deep learning continues to be the ability of methods to generalize when the number of model parameters is larger than the number of training examples. In this work, we take a step towards a better understanding of the underlying phenomena of Deep Autoencoders (AEs), a mainstream deep learning solution for learning compressed, interpretable, and structured data representations. In particular, we interpret how AEs approximate the data manifold by exploiting their continuous piecewise affine structure. Our reformulation of AEs provides new insights into their mapping, reconstruction guarantees, as well as an interpretation of commonly used regularization techniques. We leverage these findings to derive two new regularizations that enable AEs to capture the inherent symmetry in the data. Our regularizations leverage recent advances in the group of transformation learning to enable AEs to better approximate the data manifold without explicitly defining the group underlying the manifold. Under the assumption that the symmetry of the data can be explained by a Lie group, we prove that the regularizations ensure the generalization of the corresponding AEs. A range of experimental evaluations demonstrate that our methods outperform other state-of-the-art regularization techniques.

description: The variational auto-encoder (VAE) is a deep latent variable model that has two neural networks in an autoencoder-like architecture; one of them parameterizes the model's likelihood. Fitting its parameters via maximum likelihood (ML) is challenging since the computation of the marginal likelihood involves an intractable integral over the latent space; thus the VAE is trained instead by maximizing a variational lower bound. Here, we develop a ML training scheme for VAEs by introducing unbiased estimators of the log-likelihood gradient. We obtain the estimators by augmenting the latent space with a set of importance samples, similarly to the importance weighted auto-encoder (IWAE), and then constructing a Markov chain Monte Carlo coupling procedure on this augmented space. We provide the conditions under which the estimators can be computed in finite time and with finite variance. We show experimentally that VAEs fitted with unbiased estimators exhibit better predictive performance.
The teaching of Italian in British Columbia : theories, methods, computers and MAE

description: The teaching of a foreign language involves the use of methods, rooted in an approach to language teaching, and often incorporates the use of technology such as computers and multimedia. In order to examine the approach, method, and use of multimedia technology in the teaching of Italian in British Columbia at the elementary and secondary levels, it is important to first define these critical elements. The first chapter examines the global shift from using a Grammar-Translation Approach to teaching foreign languages towards using a Communicative Approach. It is interesting to note that this shift spans numerous centuries and develops gradually through a series of innovative foreign language teaching approaches and methods. The second chapter provides an in-depth look at this Communicative Approach. It examines the theories it is based on, the components a Communicative Language Teaching or CLT syllabus incorporates, as well as the classroom manifestations of CLT, including the types of activities used, the role of grammar, the learning resources used, the teacher's role, and the student's role. The chapter also reviews criticism levied against CLT. The third chapter examines the role of computer technology in foreign language teaching. As computers become ubiquitous, it is important to highlight the reason why computers go hand in hand with CLT; computer technology incorporates aspects of the theories which Communicative Approach is based upon. As such, computer technology should be part of the CLT classroom but only after the most effective Computer Assisted Language Learning or CALL program has been chosen. This chapter identifies criteria for the selection of effective CALL as well as identifying how to implement CALL in the classroom setting. In trying to examine CALL's overall value to CLT, the chapter also highlights some of the positive and negative attributes of CALL. The final chapter uses the terminology and approaches introduced in previous chapters and relates them to the actual panorama of Italian taught at the elementary and secondary levels in British Columbia. The driving force behind the use of the Communicative Approach and the use of computer technology in the local teaching of Italian comes from the Italian Ministero degli affari esteri, or MAE. This can be seen through MAE's foreign policy, their financial assistance, their trained personnel sent to assist local teachers of Italian, and their ongoing commitment to the teaching of Italian abroad. The chapter, through a questionnaire completed by local teachers of Italian, also tries to ascertain whether the resources offered by MAE are being used to their fullest.

description: We explore integrability properties of superstring equations of motion in AdS_5 x S^5. We impose light-cone kappa-symmetry and reparametrization gauges and construct a Lax representation for the corresponding Hamiltonian dynamics on subspace of physical superstring degrees of freedom. We present some explicit results for the corresponding conserved charges by consistently reducing the dynamics to AdS_3 x S^3 and AdS_3 x S^1 subsectors containing both bosonic and fermionic fields.

description: In the marketing industry, ‘brand storytelling’ has become a buzz word for the intersection between organic narratives and strong advertising. To create this organic branded content, marketers are increasingly contracting filmmakers and documentaries to produce branded documentaries. The shift from overt ads to subtle messaging in branded documentaries has helped a large number of businesses connect with consumers. Therefore, the objective of this thesis is to explore the effect of utilizing documentary film- making styles on brand content marketing. This is a work of qualitative research examining the use of storytelling via documentary film to market brands. This research aims to understand what makes the combination of storytelling and documentary filmmaking more effective than traditional overt marketing. I hope this paper can provide small businesses and marketing consultants with guidelines on how they can produce branded documentaries to improve their marketing strategy. In this thesis, I analyze brand sponsored videos and short films to identify common elements and themes present in the videos. To select the videos, I build a heuristic based on research of common metrics and categories used to define videos, such as audience retention, ability to connect with consumers, length of film. Research from published works, visual rhetoricians, and interviews from practitioners in the marketing and film industry will also inform my analysis of how documentary film styles are being adapted or imitated in brand marketing and how those strategies operate to create effective brand content.

description: If the mysterious Fermi-LAT GeV gamma-ray excess is due to an unresolved population of millisecond pulsars (MSP) in the Galactic bulge, one expects this very same population to shine in X rays. For the first time, we address the question of what is the sensitivity of current X-ray telescopes to an MSP population in the Galactic bulge. To this end, we create a synthetic population of Galactic MSPs, building on an empirical connection between gamma- and X-ray MSP emission based on observed source properties. We compare our model with compact sources in the latest Chandra source catalog, applying selections based on spectral observables and optical astrometry with Gaia. We find a significant number of Chandra sources in the region of interest to be consistent with being bulge MSPs that are as yet unidentified. This motivates dedicated multi-wavelength searches for bulge MSPs: Some promising directions are briefly discussed.

Universal Mass Scale for Bosonic Fields in Multi-Brane Worlds

description: In this paper we find an universal mass scale for all $q-$ forms in multi-brane worlds model. It is known that this model provides an ultralight mode for the fields. However, to get this, the Lagrangians considered in the literature are not covariant. In order to solve this, we propose a covariant version to multi-localize $q-$ form fields. As a consequence of the covariance, we show that all the $q$-form fields have an ultralight mode with the same mass as the gravitational one. That way we show that there is an universal mass scale for the ultralight modes of the bosonic fields. This suggests that a new physics must emerge, for all these fields, at the same scale.
description: We have separated the results of the previous version in two parts: this one, that deals just with the universal scale of mass for bosonic fields, and the other related to the crystal manyfold. The last part will be published elsewhere

description: We report on the formation and evolution of two large-scale, synchrotron-emitting jets from the black hole candidate H 1743-322 following its reactivation in 2003. In November 2003 after the end of its 2003 outburst, we noticed, in observations with the Australia Telescope Compact Array, the presence of a new and variable radio source about 4.6" to the East of H 1743-322, that was later found to move away from H 1743-322. In February 2004, we detected a radio source to the West of H 1743-322, symmetrically placed relative to the Eastern jet. In 2004, follow-up X-ray observations with {\em Chandra} led to the discovery of X-ray emission associated with the two radio sources. This likely indicates that we are witnessing the interaction of relativistic jets from H 1743-322 with the interstellar medium causing in-situ particle acceleration. The spectral energy distribution of the jets during the decay phase is consistent with a classical synchrotron spectrum of a single electron distribution from radio up to X-rays, implying the production of very high energy ($>$ 10 TeV) particles in those jets. We discuss the jet kinematics, highlighting the presence of a significantly relativistic flow in H 1743-322 almost a year after the ejection event.

description: We uncover new behaviors of the transmission of information by three quantum channels in superposition of causal orders subject to some level of noise. We find that the transmission can exhibit three different behaviors as the level of noise is varied. This multifold behavior can be explained by the different equivalence classes of quantum switch matrices related to specific combinations of causal orders. We classify these matrices using their characteristic polynomials and matrix invariants, and we calculate analytical expressions for the Holevo information in three representative cases. Our results are a step forward to understand and harness quantum control of causal orders with different levels of noise. We also study the Holevo information as function of a continuous order parameter and analyse transitions at integer values.
