Xenoxybelis

description: Genus Xenoxybelis Machado, 1993 resurrected
 Type species: Coluber argenteus Daudin, 1803, by original designation.
 Synonyms: Oxybelis Wagler, 1830; Philodryas Wagler, 1830.
 Content: (two species) Xenoxybelis argenteus (Daudin, 1803); Xenoxybelis boulengeri (Procter, 1923) species name revalidated.
 Diagnosis: Xenoxybelis can be distinguished from the other genera of Philodryadini by the following combination of characters: markedly elongated snout, forming an acuminated and sharp head shape; large number of prediastemal maxillary teeth (16-21), followed by one or two grooved postdiastemal teeth; short heart-shaped hemipenes with a well-defined papillate longitudinal crest, formed by the confluence of the body calyces, that runs medially in the asulcate surface; lateral surfaces of hemipenes covered with two to four rows of well-developed enlarged lateral spines (Fig. 4).
 Geographical distribution: Both species occur in the Amazonian region,from Colombia and Guianas to Bolivia and Paraguay (Cunha & Nascimento, 1978; Prudente et al., 2008).
 Etymology: The generic name of the South American Vine snake Xenoxybelis is formed by the Greek words Xenos- (adjective, ξέΝΟς, meaning “different”), -oxy- (adjective, Οξύς, meaning “sharp”), and -belos (noun, βέΛΟς, meaning “dart”), in reference to their external similarity with the unrelated Neotropical Vine snake genus Oxybelis Wagler, 1830.
 Comment: Zaher et al. (2009) and Grazziotin et al. (2012) placed Xenoxybelis and Pseudablabes under the synonymy of Philodryas. With this nomenclatural act, Philodryas boulengeri Werner, 1909 and Philodryas boulengeri (Procter, 1923) became secondary homonyms (Grazziotin et al., 2012),resulting in the proposition of the new replacement name georgeboulengeri for the latter species.According to our phylogenetic results, returning Philodryas georgeboulengeri (Procter,1923) to the revalidated genus Xenoxybelis eliminates the homonymy. Therefore, we revalidate the species name Xenoxybelis boulengeri (Procter, 1923).

description: Previous literature has demonstrated that low-income people are more likely to settle for poor health choices in developed countries. By using income as a budget constraint and signal for future wellbeing in a life-course utility model, we examine the connection amongst income and overweight. The data used for this study are from the China Health and Nutrition Survey (CHNS). Estimations are conducted for overweight initiation, cessation, and participation mirroring a decision to begin and a past decision to not terminate. Our findings propose that body weight and the likelihood of overweight commencement rise with additional income but at a diminishing degree, representing a concave relation; while the likelihood of overweight discontinuance declines with additional income but at an accelerating degree, suggesting a convex relation. We presume that, as opposed to developed countries, low-income people are less inclined to be overweight in China, a country in transition. This could be explained by an income constraint for unhealthy foodstuff. Nevertheless, it will switch when income surpasses the critical threshold of the concave or inverted U-shape curve indicating that low-income people appear to receive not as much utility from future health. Specifically, this adjustment seems to occur earlier for females and inhabitants of urban areas.
WATER FOR IRRIGATION, GROUNDWATER DEPLETION AND POLITICAL ECONOMY OF ENERGY SUBSIDY FOR INTENSIVE GROUNDWATER PUMPING IN IRAN

description: The depletion of groundwater resources due to irrigation water pumping in Iran has become a serious problem which threatens both rural life and sustainable development in the country. The latest estimates show that 70% of groundwater resources have been overexploited in the last 15 years. Intensive and ever-increasing use has become one of the primary reasons behind the devastation of groundwater resources, both quantitatively and qualitatively. For many years, huge energy consumption subsidies (electricity or gasoline) have been provided for pumping irrigation water from aquifers. The resulting cheap energy makes deep water pumping possible and huge investment in deepening and relocating wells feasible. Since the reforms appear to be very difficult to implement on the political level, we focus on the political economy of subsidy provision for irrigation water and energy for pumping in Iran. We analyse how the interests of rural inhabitants are represented in Iranian parliament and examine the decision-making process of the parliamentarians in voting for eliminating the subsidies. Results show that Iranian leaders follow the logic of regime maintenance and may have incentives to strategically overrepresent rural interests in the parliament. Importantly, we found that the decision to support subsidies for irrigation water is motivated by economic factors rather than by ideological incentives. Political economy appears to be a useful framework to understand the obstacles of phasing out subsidies depleting not only ground water resources but the state budget as well.

description: Apart from being a prominent player in the eld of education and having produced Canada's "who's who" ranging from Nobel laureates to previous prime ministers, the University of British Columbia (UBC) has been proactive in its sustainability initiatives. UBC signed Talloires Declaration in 1990. It became the first university to adopt a sustainability development policy in 1997 and open an office devoted to campus sustainability in 1998. With the advent of recent worldwide calls for climate change emergency, UBC understands its place in society, industry, and politics and realises its ethical responsibility and the role it can play towards producing agents of change { students, alumni, industry, government partners, etc. { for environment sustainability. To realise its ethical responsibility, UBC has produced its 20-Year Sustainability Strategy that provides an insight into the vision and aspirations of the university to attain its long-term sustainability goals. UBC is excelling in most of the objectives laid out in its sustainability strategy, except for the ones that are heavily reliant on the sustainability habits of UBC community members. The Campus and Community Planning (C+CP) department at UBC recognises that improvements can be made to increase positive collaboration of its community members to fulll UBC's sustainability objectives. C+CP wants to use this opportunity to assess the state of sustainable education imparted during orientations for the new members at UBC. The C+CP and Social Ecological Economic Development Studies (SEEDS) department at UBC are undergoing a joint planning process for increasing sustainability literacy across students, staff, and faculty at UBC. To address sustainability education at UBC, C+CP and SEEDS aim to create effective orientation programming for students, staff and faculty. Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community. The reader should bear in mind that this is a student project/report and is not an official document of UBC. Furthermore readers should bear in mind that these reports may not reflect the current status of activities at UBC.

description: Existing multi-strategy adaptive differential evolution (DE) commonly involves trials of multiple strategies and then rewards better-performing ones with more resources. However, the trials of an exploitative or explorative strategy may result in over-exploitation or over-exploration. To improve the performance, this paper proposes a new strategy adaptation method, named explicit adaptation scheme (Ea scheme), which separates multiple strategies and employs them on-demand. It is done by dividing the evolution process into several Selective-candidate with Similarity Selection (SCSS) generations and adaptive generations. In the SCSS generations, the exploitation and exploration needs are learnt by utilizing a balanced strategy. To meet these needs, in adaptive generations, two other strategies, exploitative or explorative is adaptively used. Experimental studies on benchmark functions demonstrate the effectiveness of Ea scheme when compared with its variants and other adaptation methods. Furthermore, performance comparisons with state-of-the-art evolutionary algorithms and swarm intelligence-based algorithms show that EaDE is very competitive.

The photometric data were collected between August 1997 and January 2002 as a subproject of the OGLE survey. We determine the time delay in the light curves of images A and B of HE1104-1805 to be equal to 157+/-21 days with the variability in the image B light curve leading variability of the image A. The result is in excellent agreement with the earlier determination by Ofek and Maoz. OGLE photometry of HE1104-1805 is available to the astronomical community from the OGLE Internet archive.

description: We estimate the impact of land fragmentation and crop rotation on farm productivity in rural Albania. We employ stochastic production frontier estimation approach and Tobit regression on survey data collected among farm households in Albania in 2013. Our estimates suggest that land fragmentation improves farm efficiency likely because it allows a better use of household labour during the production seasons. Our estimates also suggest that crop rotation increases farm efficiency. However, the land fragmentation dominates the crop rotation in impacting farm efficiency.

description: Microscopic two-level system (TLS) defects at dielectric surfaces and interfaces are among the dominant sources of loss in superconducting quantum circuits, and their properties have been extensively probed using superconducting resonators and qubits. We report on spectroscopy of TLSs coupling to the strain field in a surface acoustic wave (SAW) resonator. The narrow free spectral range of the resonator allows for two-tone spectroscopy where a strong pump is applied at one resonance while a weak signal is used to probe a different mode. We map the spectral hole burnt by the pump tone as a function of frequency and extract parameters of the TLS ensemble. Our results suggest that detuned acoustic pumping can be used to enhance the coherence of superconducting devices by saturating TLSs.

description: Der deutsche Milchsektor ist möglicherweise durch einen eingeschränkten Wettbewerb um Rohmilch gekennzeichnet. Dies könnte ein Wettbewerbsnachteil für Landwirte gegenüber Molkereien sein. Neben der Diskussion um die vollständige Andienungspflicht bei Abnahmegarantie werden auch die Kündigungsfristen, zu denen Landwirte eine Molkerei verlassen können, immer wieder mit der Entstehung von Markterschließungseffekten in Verbindung gebracht. Die Milchauszahlungspreise, welche Landwirte im Jahr 2015 einschließlich aller Zuschläge erhalten haben, werden dazu in einem räumlichen ökonometrischen Modell durch strukturelle Merkmale des landwirtschaftlichen Betriebs und der regionalen Wettbewerbssituation um Rohmilch erklärt. Es zeigt sich ein negativer Zusammenhang zwischen Milchauszahlungspreis und Kündigungsfrist, d.h. Landwirte mit längeren Kündigungsfristen müssen eventuell unterdurchschnittliche Auszahlungspreise akzeptieren. Die jüngste Kritik des Bundeskartellamtes wird hierdurch grundsätzlich gestützt.

description: Die vorliegende Arbeit beschäftigt sich mit dem Auftreten außerlandwirtschaftlicher Investor*innen, die ohne eigene Flächen Biogas erzeugen. Basierend auf einer Literaturrecherche und zweier Experteninterviews erfolgt die Charakterisierung außerlandwirtschaftlicher Investor*innen, die als Grundlage der Modellierung im agentenbasierten Agrarstrukturmodell AgriPoliS dient. Modellregion dieser Arbeit ist die Altmark in Sachsen-Anhalt. Es werden zwei Szenarien modelliert: Ein Basisszenario ohne Investor und eines mit Investor. Der modellierte Investor wird hypothetisch als Agent in die Region implementiert. Ziel der anschließenden Simulationen ist die Ermittlung der Effekte, die durch die Aktivitäten dieses Agenten entstehen. Dabei liegt der Fokus auf der ökonomischen Analyse des Agenten „Außerlandwirtschaftlicher Investor“, den Auswirkungen auf dem Bodenmarkt, der Ermittlung agrarstruktureller Effekte in der Gesamtregion sowie einzelbetrieblicher ökonomischer Effekte. Der außerlandwirtschaftliche Investor kann seinen Betrieb in der Simulation ökonomisch rentabel führen. Er kann positive Gewinne erzielen und sein Eigenkapital erhöhen. Die einseitige Ausrichtung auf Biogas bringt den Investor allerdings auch in starke Abhängigkeit der politischen Rahmenbedingungen. Durch das Auftreten des Investors steigen die Pachtpreise in der Region an. Das gilt sowohl für Acker-, als auch für Grünland. Die Ergebnisse legen nahe, dass ein Investor den Strukturwandel nicht beschleunigt, da im Szenario mit Investor bis zum Ende der Simulation mehr Betriebe bestehen bleiben und insbesondere kleinere Betriebe ökonomisch bessergestellt sind. Durch den Investor ändert sich die Landnutzung der übrigen landwirtschaftlichen Betriebe. Sie bauen im Szenario mit Investor mehr Energiepflanzen zur Erzeugung von Biogassubstraten an, dafür sinkt der Anteil der Fläche, auf der Getreide erzeugt wird. Bei der Grünlandnutzung zeichnet sich eine Intensivierung ab. Weidehaltung wird zu Lasten von Grassilage reduziert.

description: Many development interventions involve training of beneficiaries, based on the assumption that knowledge and skills will spread “automatically” among a wider target population. However, diffusion of knowledge (or innovations) can be slow and incomplete. We use a randomized field experiment in Uganda to assess the impact of providing incentives for knowledge diffusion, and pay trained individuals a fee if they share knowledge obtained during a financial literacy training. Our main results are that incentives increase knowledge sharing, and that it may be cost-effective to provide such incentives. We also document an absence of assortative matching in the social learning process.

description: Cet article analyse les modes de confrontation des logiques professionnelles des agriculteurs pourvoyeurs de biens publics (BP) d’origine agricole et les politiques publiques conçues pour soutenir la production de ces biens. L’introduction resitue dans une perspective de plus long terme les caractéristiques de la récente entrée en scène de la notion de biens publics dans les négociations de la Politique Agricole Commune. Elle présente également les éléments méthodologiques sur lesquels reposent les résultats, soient des enquêtes de terrain menées en 2012 et 2013 dans quatre zones agricoles d’Europe (Pieniny en Pologne, Haut Var et Marne en France, Parc national d’Exmoor en Grande-Bretagne). Puis l’article se compose de quatre sections. La première section montre que la confrontation des logiques professionnelles des agriculteurs et des politiques publiques donne naissance à deux types de BP : les premiers, de nature spontanée et principalement observés dans les Pieniny et dans le Haut Var, sont produits par la logique systémique de production des agriculteurs indépendamment de l’existence d’un soutien public. Les seconds, observés principalement dans la Marne et dans le parc national d’Exmoor, sont le fruit d’une injonction coercitive ou très fortement incitative de la politique publique, et correspondent à l’expression d’une demande sociale qui ne rencontre pas nécessairement la logique des agriculteurs. Les BP spontanés se présentent en « bouquet » cohérent du fait de la logique productive systémique qui les génère. La seconde section montre qu’aucune situation n’est figée, certains BP passant d’une catégorie à l’autre selon l’évolution des identités professionnelles des agriculteurs ou des dynamiques de destruction/protection de ces biens portées par l’action publique au fil des périodes historiques. La troisième et dernière section systématise ces observations dans un schéma de synthèse et propose quelques enseignements tirés de ces études de cas quant aux politiques publiques les plus à même de soutenir respectivement ces deux catégories de BP.

description: Ribet has proven remarkable results about non-optimal levels of residually reducible Galois representations. We focus on a non-optimal level $N$ that is the product of two distinct primes and where the Galois deformation ring is not expected to be Gorenstein. We prove a Galois-theoretic criterion for the deformation ring to be as small as possible -- that is, for there to be a unique newform of level $N$ with reducible residual representation. When this criterion is satisfied, we deduce an $R=\mathbb{T}$ theorem.

description: In this paper we show that evolution algebras over any given field $\Bbbk$ are universally finite. In other words, given any finite group $G$, there exist infinitely many regular evolution algebras $X$ such that $Aut(X)\cong G$. The proof is built upon the construction of a covariant faithful functor from the category of finite simple (non oriented) graphs to the category of (finite dimensional) regular evolution algebras. Finally, we show that any constant finite algebraic affine group scheme $\mathbf{G}$ over $\Bbbk$ is isomorphic to the algebraic affine group scheme of automorphisms of a regular evolution algebra.

Greenhouse Gas Emissions Reduction Opportunities in Business Air Travel Project

Year: 2020

description: This report is in response to the University of British Columbia’s Social Ecological Economic Development Studies’ project (SEEDS), which aims to reduce business air travel greenhouse gas emissions (GHG). Due to the global impact of COVID-19 and the social distancing measures that have been implemented, business air travel nearly came to a stop, causing a drastic reduction in GHG emissions. The University of British Columbia (UBC) has taken this opportunity to introduce a new goal in their Climate Action Plan: the reduction of business air travel emissions, with policies informed by the COVID pandemic. The SEEDS program from UBC Campus and Community Planning is creating student-led projects to focus on this goal. This project is for the SEEDS aviation emissions reduction initiative. It will focus on studying the university’s business air travel data prior to the pandemic, while also observing the approaches used to mitigate and reduce physical interaction and thus in person events, during the pandemic. Thus, drawing lessons on how these approaches can be used to continue emission reductions after the pandemic. The team conducting this project has collected pre-pandemic flight information from UBC faculties to inform the design of a framework of a tool that can be used to assess different future policy scenarios. The team also considered faculty members who are frequent business air travelers, as they may be directly affected by the outcomes of this project. However, the team was unable to consult with these travelers due to the short project timeline. With the flight data collected, the team has designed a data collection tool that will be able to analyze average GHG emissions prior to and during the pandemic, as well as a scenario analysis tool that will use the collected data to assess various policies for reducing emissions in the future. The team members are all equipped with background experience related to GHG emissions reduction and carbon life cycle assessment, which further ensures the successful completion of this project. It is expected that by 25 June 2020, the team will have finalized policy recommendations for SEEDS that will help the university in successfully reducing their air travel GHG emissions after the pandemic has ended.

description: À la fois inscrits dans l’histoire de l’agriculture et renouvelés par de nouveaux modes de vente, les circuits courts alimentaires sont restés peu étudiés en France jusque dans la période récente. Initiée en 2009 dans le cadre d’une expertise pour l’État, la recherche présentée ici vise à montrer en quoi ces circuits, dans leur diversité, révèlent les mécanismes de construction d’alternatives au modèle de marché dominant. En associant sociologie économique et sciences de gestion sur le cas des exploitations maraîchères, nous identifions trois modèles stratégiques pour les circuits courts, visant chacun des objectifs de performance spécifiques au regard des trois piliers du développement durable. Nous montrons le rôle joué à la fois par les relations sociales et les outils de gestion dans la construction de ces modèles. Ces résultats contribuent à l’analyse du lien complexe entre performance et encastrement des pratiques. Ils ont l’originalité de prendre en compte un encastrement de type gestionnaire, qu’une approche interdisciplinaire doit aider à approfondir. Ils amènent à discuter l’usage des typologies dans la recherche pour l’action et les enjeux liés à la possibilité d’un désencastrement.

description: The main goal of this paper is to set up a numerical laboratory for the study of the slow evolution of the density and of the pressure tensor profiles of an otherwise collisionless stellar system, as a result of the interactions with a minority component of heavier "particles".The effects that we would like to study are those attributed to slow collisional relaxation and generically called "dynamical friction". We start by revisiting the problem of the sinking of a satellite inside an initially isotropic, non-rotating, spherical galaxy, which we follow by means of N-body simulations using about one million particles. We then consider a quasi-spherical problem, in which the satellite is fragmented into a set of many smaller masses with a spherically symmetric initial density distribution. In a wide set of experiments, designed in order to bring out effects genuinely associated with dynamical friction, we are able to demonstrate the slow evolution of the density profile and the development of a tangentially biased pressure in the underlying stellar system, while we briefly address the issue of the circularization of orbits induced by dynamical friction on the population of fragments. The results of the simulations presented here and others planned for future investigations allow us to study the basic mechanisms of slow relaxation in stellar systems and thus may be of general interest for a variety of problems, especially in the cosmological context. Here our experiments are conceived with the specific goal to clarify some mechanisms that may play a role in the evolution of an elliptical galaxy as a result of the interaction between the stars and a significant population of globular clusters or of the merging of a large number of small satellites.

description: We present a learning algorithm for human activity recognition in videos. Our approach is designed for UAV videos, which are mainly acquired from obliquely placed dynamic cameras that contain a human actor along with background motion. Typically, the human actors occupy less than one-tenth of the spatial resolution. Our approach simultaneously harnesses the benefits of frequency domain representations, a classical analysis tool in signal processing, and data driven neural networks. We build a differentiable static-dynamic frequency mask prior to model the salient static and dynamic pixels in the video, crucial for the underlying task of action recognition. We use this differentiable mask prior to enable the neural network to intrinsically learn disentangled feature representations via an identity loss function. Our formulation empowers the network to inherently compute disentangled salient features within its layers. Further, we propose a cost-function encapsulating temporal relevance and spatial content to sample the most important frame within uniformly spaced video segments. We conduct extensive experiments on the UAV Human dataset and the NEC Drone dataset and demonstrate relative improvements of 5.72% - 13.00% over the state-of-the-art and 14.28% - 38.05% over the corresponding baseline model.

description: Estuda as revistas científicas brasileiras de acesso aberto a partir dos critérios de qualidade não cumpridos por periódicos reprovados na avaliação de indexadores. A pesquisa caracterizou-se como quantitativa em relação aos procedimentos empregados e descritiva quanto aos objetivos, com levantamento de dados por meio de consulta a duas bases de dados: Directory of Open Access Scholarly (ROAD) e Sistema Regional de Información en Línea para Revistas Científicas de América Latina, el Caribe, España y Portugal (Latindex). O universo foi delimitado pelas revistas brasileiras extraídas do ROAD, posteriormente verificadas no Latindex. Como principais resultados, encontramos que existem 1.128 revistas científicas brasileiras de acesso aberto. No que concerne à presença destas em indexadores internacionais, reparou-se que 329 títulos (29,16%) são cobertos por um a cinco serviços de indexação, 7,97% são cobertas pelo Web of Science, 22,69% pelo Scielo e 78,01% pelo Latindex. Especificamente nesse indexador, apenas 59 periódicos não atendem aos critérios mínimos de qualidade, o correspondente a 5,23% do universo de revistas científicas brasileiras de acesso aberto. Sobre a investigação dos critérios não cumpridos, mais da metade não adota geração contínua de conteúdo (81,36%), indicação das datas de submissão e aceitação de artigos (66,10%), e cumprimento da periodicidade (50,85%).

Bootstraps to Strings: Solving Random Matrix Models with Positivity

description: A new approach to solving random matrix models directly in the large $N$ limit is developed. First, a set of numerical values for some low-pt correlation functions is guessed. The large $N$ loop equations are then used to generate values of higher-pt correlation functions based on this guess. Then one tests whether these higher-pt functions are consistent with positivity requirements, e.g., $\langle \text{tr }M^{2k} \rangle \ge 0$. If not, the guessed values are systematically ruled out. In this way, one can constrain the correlation functions of random matrices to a tiny subregion which contains (and perhaps converges to) the true solution. This approach is tested on single and multi-matrix models and handily reproduces known solutions. It also produces strong results for multi-matrix models which are not believed to be solvable. A tantalizing possibility is that this method could be used to search for new critical points, or string worldsheet theories.

description: Suite à la libéralisation des échanges qui s’est accentuée en 2000, certains pays ont publié des réglementations nationales visant à limiter les importations de produits d’origine animale. Toutefois, il n’a pas été clairement démontré que ces instruments de politique avaient été liés à des objectifs sanitaires, ou à d’autres logiques sociales, politiques ou économiques. Au Sénégal, une mesure d’interdiction des importations des produits de l’aviculture et de matériels avicoles usagers, officiellement justifiée par des garanties sanitaires dans le contexte de la crise de la grippe aviaire, avait été prise en 2005. Cependant, cette mesure a soulevé des débats importants au sein des pays de l’OMC du fait que certains acteurs nationaux et pays exportateurs de viande de volaille la considèrent comme une mesure protectionniste. Ce constat peut amener à mettre l’accent sur les acteurs et la multiplicité des intérêts nationaux et même internationaux en concurrence, dans ces processus. L’objet de cet article est d’expliciter la manière dont les risques et les incertitudes sanitaires peuvent être instrumentalisés par divers acteurs. L’approche instrumentale de l’action publique (Lascoumes et Le Galès, 2004) a permis d’appréhender cet objet. Cette recherche a été menée entre 2009 et 2010 sur la base d’entretiens conduits auprès des acteurs économiques (aviculteurs, importateurs, provendiers, accouveurs), les services étatiques et la société civile (les associations d’aviculteurs, de commerçants, d’industriels, de provendiers, les interprofessions, les ONG, les associations de consommateurs, etc.) et de données statistiques, documents officiels et communiqués de presse, etc. L’analyse des résultats montre qu’a priori, la mesure de suspension des importations de produits et matériels avicoles découle de la propagation de la grippe aviaire au niveau de certains pays exportateurs. Cependant, l’analyse du processus dans une perspective diachronique montre que le processus a été initié par les actions menées par les organisations interprofessionnelles, les associations de consommateurs et les industries nationales. L’analyse laisse apparaître l’importance des idées, des règles, et même des stratégies qui sont à la base des actions des acteurs. Elle a également permis de comprendre le positionnement de ces acteurs par rapport aux discours dominants et aux règles commerciales.
