description: "Ly$α$ nebulae" are giant ($\sim$100 kpc), glowing gas clouds in the distant universe. The origin of their extended Ly$α$ emission remains a mystery. Some models posit that Ly$α$ emission is produced when the cloud is photoionized by UV emission from embedded or nearby sources, while others suggest that the Ly$α$ photons originate from an embedded galaxy or AGN and are then resonantly scattered by the cloud. At least in the latter scenario, the observed Ly$α$ emission will be polarized. To test these possibilities, we are conducting imaging polarimetric observations of seven Ly$α$ nebulae. Here we present our results for LABd05, a cloud at $z$ = 2.656 with an obscured, embedded AGN to the northeast of the peak of Ly$α$ emission. We detect significant polarization. The highest polarization fractions $P$ are $\sim$10-20% at $\sim$20-40 kpc southeast of the Ly$α$ peak, away from the AGN. The lowest $P$, including upper-limits, are $\sim$5% and lie between the Ly$α$ peak and AGN. In other words, the polarization map is lopsided, with $P$ increasing from the Ly$α$ peak to the southeast. The measured polarization angles $θ$ are oriented northeast, roughly perpendicular to the $P$ gradient. This unique polarization pattern suggests that 1) the spatially-offset AGN is photoionizing nearby gas and 2) escaping Ly$α$ photons are scattered by the nebula at larger radii and into our sightline, producing tangentially-oriented, radially-increasing polarization away from the photoionized region. Finally we conclude that the interplay between the gas density and ionization profiles produces the observed central peak in the Ly$α$ emission. This also implies that the structure of LABd05 is more complex than assumed by current theoretical spherical or cylindrical models.

Lattice Distortion and Octupole Ordering Model in CexLa1-xB6

description: Possible order parameters of the phase IV in CexLa1-xB6 are discussed with special attention to the lattice distortion recently observed. A Γ_{5u}-type octupole order with finite wave number is proposed as the origin of the distortion along the [111] direction. The Γ_8 crystalline electric field (CEF) level splits into three levels by a mean field with the Γ_{5u} symmetry. The ground and highest singlets have the same quadrupole moment, while the intermediate doublet has an opposite sign. It is shown that any collinear order of Γ_{5u}-type octupole moment accompanies the Γ_{5g}-type ferro-quadrupole order, and the coupling of the quadrupole moment with the lattice induces the distortion. The cusp in the magnetization at the phase transition is reproduced, but the internal magnetic field due to the octupole moment is smaller than the observed one by an order of magnitude.

description: Genetic variation in defence against parasite infections is fundamental for host–parasite evolution. The overall level of defence of a host individual or population includes mechanisms that reduce parasite exposure (avoidance), establishment (resistance) or pathogenicity (tolerance). However, how these traits operate and evolve in concert is not well understood. Here, we investigated genetic variation in and associations between avoidance, resistance and tolerance in a natural host–parasite system. Replicated populations of Atlantic salmon (Salmo salar) and sea trout (an anadromous form of brown trout, Salmo trutta) were raised under common garden conditions and infected with the eye fluke Diplostomum pseudospathaceum. We demonstrate significant genetic variation in the defence traits across host populations and negative associations between the traits, with the most resistant populations showing the weakest avoidance and the lowest infection tolerance. These results are suggestive of trade-offs between different components of defence and possibly underlie the genetic variation in defence traits observed in the wild. Because the three defence mechanisms affect host–parasite evolution in profoundly different ways, we emphasize the importance of studying these traits in concert.

description: In the first part of article, the outline of territorial marketing development was introduced. At the beginning, marketing was characteristic for economy and it was designed for enterprises to increase its sale and – what fallows – bring in profit. In 70’s Kotler proposed, that marketing shouldn’t be limited only for enterprises, but we can use it for non-profit organization or public institutions too. Definitions of place marketing was introduced at the next part of this text. It follows, that it always relate to some territory. Questionable is to define, which entities should initiate its elements, because of its multiplicity and diverse. The shape of this activity is dependent of development strategy for given unit of territory. That’s why the main goal of place marketing is development of local community. In the end of article there was introduced most important – according to an author – obstacle in territorial marketing development and general perspectives.

description: History refers both to the past and to the systematic study of the past. Attempts to make a case for history in economics generally emphasize the first definition. There are benefits from increased attention to the past. This paper argues that significant benefits can be gained from increased attention to the systematic study of the past, the historian’s craft. The essence of the historian’s craft is the critical evaluation of sources. Failure to critically evaluate sources has the potential to lead to erroneous conclusions, whether one is using historical documents or more recently created data.

description: The Internet has been growing significantly and become worldwide within the last several years. Initially, it was a sheer research and scientific tool, only to be become a mass communication medium. Irrespective of place and time, Internet reaches all who have access to it. Everyone may broadcast information, may post whatever content they deem proper, provided that they do not infringe any provisions of laws. Therefore, the Internet has become the most universal medium that ever existed. Furthermore, it seems that the Internet is the least expensive and the most global marketing tool, which is used by various social and professional groups. Having a website that is targeted at a very specific geographic area may bring lots of profits: one may promote a given region, attract tourists (direct contribution to the wealth of a municipality, poviat, province and the state), and encourage businesses to invest in such a region. All this activities will eventually lead to cash inflow. In consequence, relatively modest outlays may help them to reach a broad audience. The author hereof conducted the analysis of websites hosted by the Lubuskie province municipalities in terms of: 1. ability to use websites to promote their respective regions, 2. ability to share the content that is aimed at increasing tourism 3. ability to encourage businesses to invest in a given area.

description: Chemistry researchers are frequently evaluated on the perceived significance of their work with the citation count as the most commonly-used metric for gauging this property. Recent studies have called for a broader evaluation of significance that includes more nuanced bibliometrics as well as altmetrics to more completely evaluate scientific research. To better understand the relationship between metrics and peer judgements of significance in chemistry, we have conducted a survey of chemists to investigate their perceptions of previously published research. Focusing on a specific issue of the Journal of the American Chemical Society published in 2003, respondents were asked to select which articles they thought best matched importance and significance given several contexts: highest number of citations, most significant (subjectively defined), most likely to share among chemists, and most likely to share with a broader audience. The answers to the survey can be summed up in several observations. The ability of respondents to predict the citation counts of established research is markedly lower than the ability of those counts to be predicted by the h-index of the corresponding author of each article. This observation is conserved even when only considering responses from chemists whose expertise falls within the subdiscipline that best describes the work performed in an article. Respondents view both cited papers and significant papers differently than papers that should be shared with chemists. We conclude from our results that peer judgements of importance and significance differ from metrics-based measurements, and that chemists should work with bibliometricians to develop metrics that better capture the nuance of opinions on the importance of a given piece of research.

description: In this research we argue that for jurisdictions where desalinated water has been introduced as a major supply source such that long run marginal cost is rising, marginal cost pricing is: (i) efficient; (ii) delivers revenue sufficiency; and (iii) is more equitable than traditional pricing approaches. To illustrate our result we compare outcomes under different pricing structures in Western Australia, a jurisdiction where desalinated water is responsible for almost half total potable water supply. We also show that a pure volumetric charge for wastewater services is more equitable than property value based charges or a uniform tariff. The results are based on analysis of water charges for over 700,000 individual households.

description: We present an alternative definition for the Goussarov--Habiro filtration of the Z-module freely generated by oriented integral homology 3-spheres, by means of Lagrangian-preserving homology handlebody replacements (LP-surgeries). Garoufalidis, Goussarov and Polyak proved that the graded space (G_n)_n associated to this filtration is generated by Jacobi diagrams. Here, we express elements associated to LP-surgeries as explicit combinations of these Jacobi diagrams in (G_n)_n. The obtained coefficient in front of a Jacobi diagram is computed like its weight system with respect to a Lie algebra equipped with a non-degenerate invariant bilinear form, where cup products in 3-manifolds play the role of the Lie bracket and the linking number replaces the invariant form. In particular, this article provides an algebraic version of the graphical clover calculus developed by Garoufalidis, Goussarov, Habiro and Polyak. This version induces splitting formulae for all finite type invariants of homology 3-spheres.

description: (abridged) The recent evidence obtained by Briceno et al. that star-formation in Taurus-Auriga (TA) may be producing significantly fewer brown dwarfs (BDs) per star than the ONC is investigated by setting up a realistic model stellar plus BD population and explicitly taking into account a high binary proportion and dynamical evolution in the TA groups and the ONC. The Briceno result is reproduced almost exactly despite an identical IMF in both systems because many BD-BD and star-BD binaries are disrupted in the ONC thus freeing BDs, while the TA groups remain unevolved dynamically. However, the resulting populations do not have the correct star-star, star-BD and expecially BD-BD binary properties, even if a variable BD IMF is allowed for. The conclusion is therefore that BDs need to be added as a separate population which has its own binary properties. Such an extra population can have various origins which are briefly discussed in this contribution but more fully in an associated paper.

description: We examine how media coverage of fluctuations in the price of agricultural commodities affects these prices and their volatility. We develop a unified empirical framework to analyze the media’s effects on both returns and volatility using insights from the literature. We use daily prices of futures contracts for soybeans, hard wheat, soft wheat, rice, and maize, complemented by a unique dataset that follows a comprehensive set of global media outlets and uses an algorithm to determine sophisticated relationships among phrases in a news article which signal an increase or decrease in the price of those four commodities. We find price effects that are economically important in size. Our estimates imply a net increasing effect of media coverage on the price of these four commodities; these effects are mostly concentrated in 2012 and from 2015 onwards, meaning that these effects are important in periods of both high and low prices. Across commodities, the price effects are concentrated in soybeans and maize. We find robust evidence that media coverage decreases volatility for these agricultural commodities on average for the period we study. The effects on volatility balance each other, with decreasing price coverage decreasing the variance of returns and increasing price coverage increasing the variance of returns of futures contracts of these commodities; however, the increase is than the decrease. Our results suggest that media coverage increases periods of normal volatility and decreases periods of excessive volatility. These results point to the potential of using media coverage to bring attention to price surges and to decrease volatility during food crises or times when there is above-normal volatility. The dynamics between the price of agricultural commodities and media coverage may help prevent knee-jerk policy reactions by discouraging market overreaction, encouraging market stability, and promoting food security. They highlight crucial role of providing appropriate information as fast as possible so media coverage and reflects the fundamentals that drive food commodity prices.

description: We present a formalism for coupling a density functional theory-based quantum simulation to a classical simulation for the treatment of simple metallic systems. The formalism is applicable to multiscale simulations in which the part of the system requiring quantum-mechanical treatment is spatially confined to a small region. Such situations often arise in physical systems where chemical interactions in a small region can affect the macroscopic mechanical properties of a metal. We describe how this coupled treatment can be accomplished efficiently, and we present a coupled simulation for a bulk aluminum system.

description: This thesis presents three independent paper-style empirical studies in computational finance, leveraging methods from computer science and complex network analysis.
In Chapter 1, we aim to contribute to the literature by introducing a novel classification model that takes into consideration unstructured Twitter data and metadata to categorise tweets based on the value-relevance of their information content. Our classifier shows promising results, achieving a 5-fold cross-validation accuracy of 82.1%. In Chapter 2, insider trading data from the U.S. Securities and Exchange Commission (SEC) are analysed to assess the profitability of their transactions. Sentiment analysis and social media data are incorporated to gauge the public sentiment surrounding these transactions. Insiders’ purchase transactions yield statistically significant abnormal returns in the short term, indicating their superior knowledge of their companies’ future performance compared to the general public. These findings can provide valuable insights for regulators, highlighting potential trading opportunities based on non-public information.
Chapter 3 examines a real central clearing counterparty network encompassing 15 central clearing counterparties (CCPs) and 350 clearing members (CMs). A simulation model is proposed to study the transmission of shocks in this network, particularly exploring the repercussions if CCPs were to face a common global stress event such as the default of multiple globally systemically important banks (GSIBs). We also investigate how variations in margin requirements as well as variations in the network structure could impact the default rate in the system. We find a positive correlation between the average default rate in the system and the number of defaulting GSIBs, and a non-linear relationship between changes in the variation margin and the default rate. Additionally, we find evidence that as the network grows, it becomes more resilient. This stress testing approach can help regulators capture and assess the shared cross-border risk factors among CCPs.

Throughout this time, a large number of organizations and individuals have formulated responses and expressed concern about the criteria and the process through which the criteria were developed. Collectively, our organizations consider that the “Data Repository: Selection Criteria that Matter” recommendations - as currently conceived - will act as an impediment to achieving these aims. As such, we are issuing this Joint Position Statement to highlight the community’s concerns and request that the authors of these criteria respond with specific actions.

description: A food system at the University of British Columbia (UBC), which obtains food from local sources can have direct benefits to consumers in the form of fresh and nutritious food. As well, the local economy is boosted when local farmers and food producers are supported, and reduced food mileage saves the environment. Finally a sense of caring and community can be fostered at UBC as consumers build a connection to their food source. Supporting and strengthening the local food shed is essential in creating a sustainable campus. The UBC Food Systems Project (UBCFSP) is implementing new initiatives to move the UBC food system towards sustainability. Guided by the objectives of Scenario 4 of the UBCFSP: Extending BC local food purchasing on campus, Group 4 investigated the following: Local food initiatives adopted by the University of Toronto (U of T) in collaboration Local Flavor Plus (LFP), The Vancouver Food Policy Council, Small Potato Urban Delivery (SPUD), UBC Food Services (UBCFS), Sage Bistro and Natty King (a local producer). Data was collected via literature reviews, phone interviews and email correspondence. Group 4 acted as a catalyst in initiating a business relationship between Sage Bistro, SPUD and UBCFS. The project culminated as a focus group attended by representatives of the organizations listed above as well as Liska Richer, UBCFSP Coordinator and Group 4 members. As a result of the focus group Sage Bistro will incorporate local foods acquired from SPUD into their menu on a trial bases to test customer reception and further explore the business potential of incorporating local foods into their menu. In the long-term alternative local food producers and distributors will need to be explored as a means to meet increased quantity and variety demands by Sage Bistro and potentially other UBC food providers.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions.

description: The efficiency of the Slovak agriculture, when compared with the EU and CEFTA countries, is influenced by a number of factors. Their importance is varied since it is determined especially by the level of development of a particular national economy. In Slovakia, the 1996 GDP per capita reached only 45 per cent of the average GDP in the EU countries. Other factors include the agricultural trade deficit, constantly low investment of foreign capital into agriculture as well as high level of technical and economic obsolence of agricultural property. Despite the fact that Slovak agriculture has preserved its large scale production character, with the average size of an enterprise being 1 600 ha of land, its current efficiency parameters fall behind not only the EU level, but the potential efficiency level of the production factors as well. The 1996 agricultural production reached not more than 95 per cent of the pre-transformational level - both in the animal and plant production parameters. Despite the fact that there has been a decrese of the number of agricultural employees, they still represent a higher percentage (6,7 per cent) of the total countrys employment than in the EU countries (5,2 per cent). As far as the support of domestic producers is concerned, the subsidies represent 70 - 80% of the Uruguay Round of GATT subsidizing policy. If compared with the EU, there are also differences in the Producer Subsidy Equivalent which is the subject of discussions in spite of the fact that it reaches only 50 per cent of the EU level. The future direction of the subsidy policy is also discussed.

description: A microscopic calculation of ground state entanglement for the XY and Heisenberg models shows the emergence of universal scaling behavior at quantum phase transitions. Entanglement is thus controlled by conformal symmetry. Away from the critical point, entanglement gets saturated by a mass scale. Results borrowed from conformal field theory imply irreversibility of entanglement loss along renormalization group trajectories. Entanglement does not saturate in higher dimensions which appears to limit the success of the density matrix renormalization group technique. A possible connection between majorization and renormalization group irreversibility emerges from our numerical analysis.

description: We have developed a new halo finding method, Physically Self-Bound (PSB) group finding algorithm, which can efficiently identify halos located even at crowded regions. This method combines two physical criteria such as the tidal radius of a halo and the total energy of each particle to find member particles. Two hierarchical meshes are used to increase the speed and the power of halo identification in the parallel computing environments. First, a coarse mesh with cell size equal to the mean particle separation $l_{\rm mean}$ is used to obtain the density field over the whole simulation box. Mesh cells having density contrast higher than a local cutoff threshold $δ_{\rm LOC}$ are extracted and linked together for those adjacent to each other. This produces local-cell groups. Second, a finer mesh is used to obtain density field within each local-cell group and to identify halos. If a density shell contains only one density peak, its particles are assigned to the density peak. But in the case of a density shell surrounding at least two density peaks, we use both the tidal radii of halo candidates enclosed by the shell and the total energy criterion to find physically bound particles with respect to each halo. Similar to DENMAX and HOP, the \hfind method can efficiently identify small halos embedded in a large halo, while the FoF and the SO do not resolve such small halos. We apply our new halo finding method to a 1-Giga particle simulation of the $Λ$CDM model and compare the resulting mass function with those of previous studies. The abundance of physically self-bound halos is larger at the low mass scale and smaller at the high mass scale than proposed by the Jenkins et al. (2001) who used the FoF and SO methods. (abridged)

description: This article is concerned with the derivation of numerical reconstruction schemes for the inverse moving source problem on determining source profiles in (time-fractional) evolution equations. As a continuation of the theoretical result on the uniqueness, we adopt a minimization procedure with regularization to construct iterative thresholding schemes for the reduced backward problems on recovering one or two unknown initial value(s). Moreover, an elliptic approach is proposed to solve a convection equation in the case of two profiles.

description: The paper analyzes the recent transformation of the Venezuelan agriculture within the framework of the macroeconomic adjustments implemented since the early eighties. The improvement of performance of the Venezuelan agriculture can not take place unless there is economic stability and adequate macroeconomic policies are undertaken. There is need to continue market-oriented reforms to gain from trade based on comparative advantages. Reformers must be aware of costs associated with the transition period.
Implementing a Language for Distributed Systems: Choices and Experiences with Type Level and Macro Programming in Scala

description: Multitier programming languages reduce the complexity of developing distributed systems by developing the distributed system in a single coherent code base. The compiler or the runtime separate the code for the components of the distributed system, enabling abstraction over low level implementation details such as data representation, serialization and network protocols. Our ScalaLoci language allows developers to declare the different components and their architectural relation at the type level, allowing static reasoning about about distribution and remote communication and guaranteeing static type safety across components. The compiler splits the multitier program into the component-specific code and automatically generates the communication boilerplate. Communication between components can be modeled by declaratively specifying data flows between components using reactive programming. In this paper, we report on the implementation of our design and our experience with embedding our language features into Scala as a host language. We show how a combination of Scala's advanced type level programming and its macro system can be used to enrich the language with new abstractions. We comment on the challenges we encountered and the solutions we developed for our current implementation and outline suggestions for an improved macro system to support the such use cases of embedding of domain-specific abstractions.

description: Second-order finite volume (FV) methods are still the predominant technique for industrial CFD applications. The meshes used for the simulation of steady state fluid flows have been automated and are designed to capture the required aerodynamic forces. However, these meshes lack the ability to resolve the unsteady features. To address this limitation, additional meshes that are refined along the path of all unsteady features have to be generated. This work proposes a scheme that combines the advantages of both second-order vertex-centred FVs and high-order HDG, to enable the computation of wind gust effects on aerodynamic shapes using the same meshes employed to simulate steady flows within a FV framework. The use of vertex-centred FVs in the vicinity of the aerodynamic shape ensures a minimum number of degrees of freedom when compared to FV methods and it avoids the need for generating a high-order curvilinear mesh. The use of HDG guarantees a low number of degrees of freedom compared to other DG methods. The coupling between both techniques is performed by introducing a set of transmission conditions between the FV and HDG subdomains, thus ensuring conservation.

description: A growing number of teachers have undertaken National Board for Professional Teaching Standards (NBPTS) certification training since its inception over twenty-five years ago. Previous empirical research on the impact of NBCTs on student performance has focused on state or districtlevel exams in individual states and found mixed results. This study examines the relationship between National Board Certified Teachers (NBCTs) and student achievement on the reading and math assessments of the National Assessment of Educational Progress (NAEP). We argue that achievement can be affected both directly by the certified teacher and indirectly as NBCTs provide mentoring to colleagues and assume school leadership positions. This study focuses on a nationally representative assessment to measure student achievement rather than state- or district-level assessment exams. We find that the percentage of National Board certified teachers in a state is positively related to scores on state-level NAEP Reading and Math assessments.

description: We contrast the experimental signatures of low energy supersymmetry and the model of Universal Extra Dimensions and discuss various methods for their discrimination at hadron colliders. We study the discovery reach of the Tevatron and the LHC for level 2 Kaluza-Klein modes, which would indicate the presence of extra dimensions. We find that with 100 ${\rm fb}^{-1}$ of data the LHC will be able to discover the $γ_2$ and $Z_2$ KK modes as separate resonances if their masses are below 2 TeV. We also investigate the possibility to differentiate the spins of the superpartners and KK modes by means of the asymmetry method of Barr.
