description: (Abridged) We are conducting a survey of Galactic shell-type supernova remnants (SNRs) known or suspected to possess non-thermal components to their X-ray emission using new and archived observations made with such X-ray satellites as ROSAT, ASCA, RXTE, Chandra and XMM-Newton. This research is intended to probe the phenomenon of cosmic-ray acceleration by Galactic SNRs and estimate the maximum energy of cosmic-ray electrons accelerated by these sources. To illustrate this work, we examine the X-ray spectrum of the northwestern rim of an SNR suspected to have a non-thermal component to its X-ray emission, G156.2+5.7 (RX J04591+5147), over the energy range of approximately 0.7-12.0 keV using observations made by the ASCA GIS and the RXTE PCA. We compare fits made to the non-thermal component using two models, a simple power law and SRCUT. Both models give acceptable fits: the photon index derived from the fit made with the power law model, 2.0 (+0.2, -0.5), is comparable to values obtained for the bright rims of other SNRs with hard X-ray spectra. Using the SRCUT model, we derive a value of 2.42 (+0.24, -0.23) x 10^17 Hz for the cutoff frequency: based on this value and assuming a mean magnetic field strength of 14 microGauss, we estimate the cutoff energy of cosmic-ray electrons accelerated by G156.2+5.7 to be approximately 32 TeV. This energy value is well short of the "knee" feature of the cosmic-ray spectrum.

description: We present a novel approach to Gaussian Berezin correlation functions. A formula well known in the literature expresses these quantities in terms of submatrices of the inverse matrix appearing in the Gaussian action. By using a recently proposed method to calculate Berezin integrals as an expectation of suitable functionals of Poisson processes, we obtain an alternative formula which allows one to skip the calculation of the inverse of the matrix. This formula, previously derived using different approaches (in particular by means of the Jacobi identity for the compound matrices), has computational advantages which grow rapidly with the dimension of the Grassmann algebra and the order of correlation. By using this alternative formula, we establish a mapping between two fermionic systems, not necessarily Gaussian, with short and long range interaction, respectively.

description: This paper introduces the first objective space algorithm which can exactly find all supported and non-supported non-dominated solutions to a mixed-integer multi-objective linear program with an arbitrary number of objective functions. This algorithm is presented in three phases. First it builds up a super-set which contains the Pareto front. This super-set is then modified to not contain any intersecting polytopes. Once this is achieved, the algorithm efficiently calculates which portions of the super-set are not part of the Pareto front and removes them, leaving exactly the Pareto front.

description: We report the results of an XMM-Newton observation of the persistent X-ray source 1E1743.1-2843, located in the Galactic Center (GC) direction. We determine the position of the source at alpha_J2000=17h46m21.0s, delta_J2000=-28deg43'44" (with an uncertainty of 1.5"), which is the most accurate to date, and will enable cross-identifications at other wavelengths. The source was bright during this observation (L_2-10keV ~ 2.7 x 10^36 d^2_10kpc erg/s for a power-law continuum), with no significant variability. We propose that 1E1743.1-2843 may be explained in terms of a black hole candidate in a low/hard state. There is an indication that the source exhibits different states from a comparison of our results with previous observations (e.g., ART-P, BeppoSAX). However, the present spectral analysis does not rule out the hypothesis of a neutron star low-mass X-ray binary as suggested previously. If 1E1743.1-2843 is actually located in the GC region, we might expect to observe significant 6.4keV fluorescent iron line emission from nearby molecular clouds (e.g., GCM+0.25+0.01).

GL(2)-geometry and complex structures

description: We study $GL(2)$-structures on differential manifolds. The structures play a fundamental role in the geometric theory of ordinary differential equations. We prove that any $GL(2)$-structure on an even dimensional manifold give rise to a certain almost-complex structure on a bundle over the original manifold. Further, we exploit a natural notion of integrability for the $GL(2)$-structures, which is a counterpart of the self-duality for the 4-dimensional conformal structures. We relate the integrability of the $GL(2)$-structures to the integrability of the almost-complex structures. This allows to perform a twistor-like construction for the $GL(2)$-geometry. Moreover, we provide an explicit construction of a canonical connection for any $GL(2)$-structure.

description: Previous research has demonstrated that religious persuasion can have an impact on environmental attitudes, however less research of this kind has focused on the relationship between religious persuasion and climate change attitudes. Using a survey of 1,927 Australians we examined links between membership of five religious groupings and climate change attitudes, as well as membership of climate change household segments that differ in their acceptance of human induced climate change and the need for policy responses. Differences were found across religious groups in terms of their belief in human induced climate change, consensus among scientists, their own efficacy and the need for policy responses. Using ordinal regression, some of these differences were shown to be due to sociodemographic factors, knowledge, environmental attitude or political conservatism. However, significant effects due to religious persuasion remained, and they range from medium to large in size. Options for responding to these effects are discussed.

description: Few existing studies in the literature devoted efforts to examine the driver injury severity in left-turn crashes. To fill this research gap, this paper aims to provide a comprehensive study of the contributing factors of left-turn crashes and the corresponding injury severities. The hierarchical ordered probit (HOPIT) model is first applied to study driver injury severity in left-turn crashes. The HOPIT model can overcome the limitations of traditional ordered probit models since its thresholds are always positive and ordered. It is a function of unique explanatory parameters that do not necessarily affect the ordered probability outcomes directly. Considering the driving condition during the wintertime could be significantly different from other seasons, this study divided the overall crash dataset into “winter” and “other-season” subsets based on the temperature, snowing condition, and other factors. With the “other-season” dataset, results demonstrated that contributing factors, such as young drivers, male drivers, clear, light, and ramp intersection with crossroad, are associated with a decrease in injury severity. On the contrary, factors like drug, alcohol, disregard traffic control device, high-speed limit, the protected left-turn signal, etc., are related to an increase in injury severity. In winter, results revealed that only nine contributing factors are significant to the left-turn crash. Alcohol, disregard traffic control device, nighttime, high-speed limit, head-on collision, and state road are associated with an increase in injury severity. Also, two-vehicle involved, snow, ramp intersection with crossroad are related to a decrease in injury severity. The HOPIT model is applied to examine contributing factors of left-turn crashes and the corresponding injury severity, based on left-turn crash records from 2010 to 2017 in Utah. Eighteen significant factors of left-turn crash injury severity are identified in the overall dataset. In seasons rather than winter, the significant factors are almost the same as that of the entire year. In the winter, less significant factors and different patterns are found compared with the overall crashes.

Year: 2020

description: The embedded laminated glass connection belongs to the group of the most widely used ways of the glass components connecting. As it becomes common to use glass as a material for load-bearing elements, the connection must be able to bear stresses arising during the lifetime period. To find out the load capacity of the connection under different loads, experiments have to be performed. Within the ongoing research at the Faculty of Civil Engineering of Czech Technical University in Prague, two series of experiments of the embedded laminated glass connection have been performed. There were two sets of identical samples. Both sets included several combinations of glass panes and types of foils. The first series of tests was focused on the characteristics of this type of connection under the short-term tensile loads. The second one was dealing with the characteristics under the short-term eccentric shear loads. Due to using the identical samples for both series of tests, it was possible to compare the obtained results. The experiments show that the tensile load capacity of the connection is much higher than its eccentric shear load capacity. It also reveals reaching the tensile resistance limit of the weakened glass pane as a dominant mode of failure. However, further research consisting of numerical modelling and additional experiments is in progress.

In this work we analyse the effects of these background radiations on the observations of PSRs at 1400 MHz and SNRs at 1000 MHz. In the interval l=0$^o$$\pm60^o$ the PSRs with flux F$_{1400}$$>$0.2 mJy and the SNRs with surface brightness $Σ$$>10^{-21}$ Wm$^{-2}$Hz$^{-1}$sr$^{-1}$ are observable for all values of l and b. All the SNRs with $Σ$$>3\times10^{-22}$ Wm$^{-2}$Hz$^{-1}$sr$^{-1}$ can be observed in the interval 60$^o$$

description: To achieve water quality targets, management practice change in the sugar cane industry has been a large focus for natural resource management initiatives such as Reef Plan and Reef Rescue. Considerable public funds have been targeted at landholders to change on-ground management practices. However, the economic implications for landholders are not well understood. To further inform future policy development of the upcoming Reef Water Quality Protection Plan 3 and Reef Rescue 2, the economic costs and benefits to landholders are required. This research used a case study approach to consider the economic implications of improved soil management through an extended fallow period in the Mackay-Whitsunday region. The results demonstrate the complexity of creating effective policy design for adoption of improved management practices for water quality in a semi perennial farming system.

description: We solve a model of a qubit strongly coupled to a massive environmental oscillator mode where the qubit backaction is treated exactly. Using a Ginzburg-Landau formalism, we derive an effective action for this well known localization transition. An entangled state emerges as an instanton in the collective qubit-environment degree of freedom and the resulting model is shown to be formally equivalent to a Fluctuating Gap Model (FGM) of a disordered Peierls chain. Below the transition, spectral weight is transferred to an exponentially small energy scale leaving the qubit coherent but damped. Unlike the spin-boson model, coherent and effectively localized behaviors may coexist.

description: Connecting glass with heat bonds is a way to create all-transparent glass structures. Two methods have been researched in theory and practice, glass welding, through local heating, and glass fusion through global heating. Both methods have been applied to produce 10 mm thick T-sections of soda lime glass while preventing thermal shock failure and minimizing residual stress. These specimen, and specimen with an adhesive joint, have been tested destructively. It is concluded that it is possible to connect 10 mm thick soda lime glass by welding, if the glass is preheated and the surrounding temperature remains elevated during the welding process. Additionally, glass fusion of a similar product through global heating is possible for the applied temperature schedule. The mould has a paramount inﬂuence on the quality of the product. For both production methods, the annealing schedule was adequate to reduce residual stress. The average strength of the fused specimen was 44% larger. The standard deviation of the welded specimen was smaller: the standard deviation relative to the mean value was 9% for the welded specimen and 60% for the fused specimen. However, the amount of tested specimen is little. This research is a proof of concept for heat bonding soda lime glass of a structurally relevant thickness.

description: The paper explores the macroeconomic consequences of fiscal consolidations whose timing and composition - either tax- or spending-based - are uncertain. We find that the composition of the fiscal consolidation, its duration, the monetary policy stance, the level of government debt, and expectations over the likelihood and composition of fiscal consolidations all matter in determining the extent to which a given consolidation is expansionary or successful in stabilizing government debt. We argue that the conditions that could render fiscal consolidation efforts expansionary are unlikely to apply in the current economic environment.
description: L’étude explore les conséquences macroéconomiques de programmes d’assainissement budgétaire dont on ne connaît avec certitude ni le calendrier, ni la composition (l’État haussera-t-il les impôts ou réduira-t-il ses dépenses?). Les auteurs montrent que la composition d’un programme donné, sa durée, les anticipations relatives à la vraisemblance de sa mise en oeuvre et à sa composition, l’orientation de la politique monétaire et le niveau de la dette publique influent tous sur la mesure dans laquelle ce programme aura des effets expansionnistes ou réussira à stabiliser la dette publique. Ils jugent peu probable, dans le contexte économique actuel, que les conditions nécessaires pour que les efforts de redressement budgétaire stimulent l’activité économique soient réunies.

description: With increasing signs of climate change and the influence of national and international carbon-related laws and agreements, governments all over the world are grappling with how to rapidly transition to low-carbon living. This includes adapting to the impacts of climate change that are very likely to be experienced due to current emission levels (including extreme weather and sea level changes), and mitigating against further growth in greenhouse gas emissions that are likely to result in further impacts. Internationally, the concept of ‘Biophilic Urbanism’, a term coined by Professors Tim Beatley and Peter Newman to refer to the use of natural elements as design features in urban landscapes, is emerging as a key component in addressing such climate change challenges in rapidly growing urban contexts. However, the economics of incorporating such options is not well understood and requires further attention to underpin a mainstreaming of biophilic urbanism. Indeed, there appears to be an ad hoc, reactionary approach to creating economic arguments for or against the design, installation or maintenance of natural elements such as green walls, green roofs, streetscapes, and parklands. With this issue in mind, this paper will overview research as part of an industry collaborative research project that considers the potential for using a number of environmental economic valuation techniques that have evolved over the last several decades in agricultural and resource economics, to systematically value the economic value of biophilic elements in the urban context. Considering existing literature on environmental economic valuation techniques, the paper highlights opportunities for creating a standardised language for valuing biophilic elements. The conclusions have implications for expanding the field of environmental economic value to support the economic evaluations and planning of the greater use of natural elements in cities. Insights are also noted for the more mature fields of agricultural and resource economics.

description: The authors study the implications of fiscal policy behaviour for sovereign risk in a framework that determines a country’s fiscal limit, the point at which, for economic or political reasons, taxes and spending can no longer adjust to stabilize debt. A real business cycle model maps the economic environment - expected fiscal policy, the distribution of exogenous disturbances and private agents’ behaviour - into a distribution for the maximum sustainable debt-to-GDP ratio. Default is possible at any point on this fiscal limit distribution. Calibrations of the model to Greek and Swedish data illustrate how the framework can be used to study actual fiscal reforms undertaken by developed economies facing sovereign risk pressures.

Un modèle de cycles réels transpose le contexte économique - politique budgétaire attendue, distribution des chocs exogènes et comportement des agents privés - en une distribution de ratios dette/PIB viables maximaux. Une défaillance est possible en tout point de cette distribution. Le modèle est étalonné en fonction des données relatives à la Grèce et à la Suède afin d’illustrer comment il peut servir à étudier des réformes budgétaires réellement entreprises dans des pays développés dont la prime de risque souverain subit des pressions à la hausse.

Our results indicate that a DCE debrie ng question that asks respondents to rank the importance of attributes helps to explain the resulting choices. We also examine how mode of survey delivery (online and mail) impacts model performance, nding that results are not substantively a¤ected by the mode of survey delivery. We conclude that the ranking data is a complementary source of information about respondent utility functions within hypothetical DCEs.
Structural Silicone Glazing - Design & Modelling

Publisher: name: Challenging Glass Conference Proceedings
Year: 2020

description: The use of Structural silicone glazing (SSG) systems in large commercial glazed facades is well established in current practice, mainly due to the architectural aspiration of having a continuous smooth glass surface across the building elevation. Enhanced thermal and security (blast) performance are typically listed as an advantage for this particular type of systems. SSG façade systems are structurally complex due to the fact that multiple load-paths can be identified within the system. It is accepted as good practice to detail façade panels so that the dead load of the glass is not carried through the structural silicone. But can this be achieved in reality? The aim of this paper is to identify and discuss challenges with the assumption that the SSG is isolated from the glass self weight and provide a better understanding on the complexity of SSG systems. The influence of stress/strain and creep due to the long-term load on the system capacity will be investigated. Some degree of long term loads are usually present due to detailing and real system behaviour. Real project examples will be used to identify opportunities for improvement and findings will be summarised at the end of the paper.

title: Volatility and Liquidity Costs
Creators: name: Chaker, Selma
Publisher: name: Bank of Canada
Year: 2013

description: Observed high-frequency prices are contaminated with liquidity costs or market microstructure noise. Using such data, we derive a new asset return variance estimator inspired by the market microstructure literature to explicitly model the noise and remove it from observed returns before estimating their variance. The returns adjusted for the estimated liquidity costs are either totally or partially free from noise. If the liquidity costs are fully removed, the sum of squared high-frequency returns - which would be inconsistent for return variance when based on observed returns - becomes a consistent variance estimator when based on adjusted returns. This novel estimator achieves the maximum possible rate of convergence. However, if the liquidity costs are only partially removed, the residual noise is smaller and closer to an exogenous white noise than the original noise. Therefore, any volatility estimator that is robust to noise relies on weaker noise assumptions if it is based on adjusted returns than if it is based on observed returns.
description: Les prix des actifs observés à haute fréquence sont « contaminés » par des coûts de liquidité ou du bruit en raison de la présence d’effets de microstructure. S’inspirant de la littérature qui étudie la microstructure des marchés, l’auteure met au point un nouvel estimateur qui permet de modéliser explicitement le bruit à partir de ces données et de l’éliminer des rendements observés de l’actif avant d’estimer leur variance. Les rendements corrigés des coûts de liquidité estimés sont totalement ou partiellement exempts de bruit. Dans le cas où les coûts de liquidité sont entièrement retranchés, la somme des carrés des rendements à haute fréquence devient un estimateur convergent de la variance si celle-ci est calculée sur la base des rendements corrigés et non sur celle des rendements observés. Ce nouvel estimateur converge à une vitesse maximale. Toutefois, lorsqu’une partie seulement des coûts de liquidité est éliminée, le bruit résiduel est plus petit et plus proche d’un bruit blanc exogène que le bruit initial. En conséquence, un estimateur robuste de la volatilité n’exige pas d’hypothèses aussi fortes sur le bruit s’il est fondé sur les rendements corrigés plutôt que sur les rendements observés.
ДИХОТОМИЯ «СВОЙ» – «ЧУЖОЙ» В АНИМАЛИСТИЧЕСКОЙ КАЛМЫЦКОЙ БАЛЛАДЕ

description: В статье рассматривается дихотомия «свой» – «чужой» в анималистической балладе калмыцких поэтов ХХ в. Актуальность исследования определяется недостаточной изученностью баллады калмыцких поэтов на тему литературного бестиария. Целью статьи является исследование поэтики калмыцкой литературной баллады на тему взаимоотношений человека и животных в аспекте позиции, оппозиции и диспозиции. В балладах Тимофея Бембеева «Җиврнь тәәрңхә тоһрун» («Баллада о подрезанных крыльях»), Владимира Нурова «Баргин туск баллад» («Баллада о псе Балтыке»), Михаила Хонинова «Әм залһсн шовум дуулна» («О птице, раненной в бою») 1960–1970-х гг. дихотомия «свой» – «чужой» манифестирует мир природы и мир человека как в конфликте друг против друга, так и в союзе. Если в героико-патриотических и политических балладах калмыцких авторов главные персонажи обычно обозначены конкретными именами, то в анималистических балладах люди обезличены: безымянный рассказчик актуализирует то или иное происшествие, акцентируя морально-нравственные ценности; персонажи-животные, как правило, не персонализированы, за исключением пса по имени Балтык в балладе В. Нурова. Историко-литературный и сравнительно-сопоставительный методы позволяют выявить авторские интенции в изображении людей и животных, диких и домашних, в конфликтных ситуациях войны и мира, свободы и неволи, добра и зла, преданности и вражды, силы и слабости. Поэтика калмыцкой баллады подчеркивает жанровую природу произведения, выраженную либо в названии, либо в подзаголовке оригинального текста или русского перевода. Экологическая тема в сюжетах транслируется авторами как любовь к родному краю, защита и сбережение мира животных. Национальное мировидение калмыцких поэтов проецирует картину степной фауны в ракурсе народной культуры, обычаев и верований. Сохраняя традиции национальной версификации, поэты структурируют тексты по-разному: без деления на строфику (Т. Бембеев), с делением на катрены (В. Нуров, М. Хонинов). Зоопоэтика анималистической баллады трех поэтов ближе к рассказу в стихах.
title: Real-financial Linkages through Loan Default and Bank Capital
Creators: name: Takamura, Tamon
Publisher: name: Bank of Canada

description: Many studies in macroeconomics argue that financial frictions do not amplify the impacts of real shocks. This finding is based on models without endogenous default on loans and bank capital. Using a model featuring endogenous interactions between firm default and bank capital, this paper revisits the propagation mechanisms of real and financial shocks. The model, calibrated to the US economy, shows that real shocks translate into a financial problem and cause persistent business cycle fluctuations through countercyclical firm default and interest-rate spread. Consistent with the previous studies, financial shocks lead the economy into booms and recessions, notably during the US financial crisis. Capital injections to banks through the Troubled Asset Relief Program were an effective policy response for mitigating the vicious cycle between loan default and interest-rate spread.
description: D’après de nombreuses études macroéconomiques, les frictions financières n’amplifieraient pas les répercussions des chocs réels. Cependant, cette constatation est fondée sur des modèles qui ne tiennent pas compte des défauts de paiement et des fonds propres bancaires endogènes. À partir d’un modèle intégrant des interactions endogènes entre défaillances d’entreprises et fonds propres bancaires dans l’économie américaine, la présente étude revisite les mécanismes de propagation des chocs réels et des chocs financiers. Les résultats montrent que les chocs réels deviennent un problème financier donnant lieu à des fluctuations persistantes du cycle économique du fait de défaillances d’entreprises et d’écarts de taux d’intérêt contracycliques. Conformément aux conclusions des autres études, les chocs financiers entraînent l’économie dans des cycles d’expansion et de récession, comme pendant la crise financière aux États-Unis. Les injections de capitaux que le gouvernement a alors offertes aux banques par l’intermédiaire du Troubled Asset Relief Program ont été efficaces pour combattre le cercle vicieux où les défauts de paiement mènent à des écarts de taux d’intérêt et viceversa.

description: Spin-orbit coupling (SOC) has gained much attention for its rich physical phenomena and highly promising applications in spintronic devices. The Rashba-type SOC in systems with inversion symmetry breaking is particularly attractive for spintronics applications since it allows for flexible manipulation of spin current by external electric fields. Here, we report the discovery of a giant anisotropic Rashba-like spin splitting along three momentum directions (3D Rashba-like spin splitting) with a helical spin polarization around the M points in the Brillouin zone of trigonal layered PtBi2. Due to its inversion asymmetry and reduced symmetry at the M point, Rashba-type as well as Dresselhaus-type SOC cooperatively yield a 3D spin splitting with alpha~ 4.36 eVA in PtBi2. The experimental realization of 3D Rashba-like spin splitting not only has fundamental interests but also paves the way to the future exploration of a new class of material with unprecedented functionalities for spintronics applications.

description: (abridged) We model the nucleosynthesis during the thermal pulse phase of a rotating, solar metallicity AGB star of 3M_sun. Rotationally induced mixing during the thermal pulses produces a layer (~2E-5M_sun) on top of the CO-core where large amounts of protons and C12 co-exist. We follow the abundance evolution in this layer, in particular that of the neutron source C13 and of the neutron poison N14. In our AGB model mixing persists during the entire interpulse phase due to the steep angular velocity gradient at the core-envelope interface. We follow the neutron production during the interpulse phase, and find a resulting maximum neutron exposure of tau_max =0.04 mbarn^-1, which is too small to produce any significant s-process. In parametric models, we then investigate the combined effects of diffusive overshooting from the convective envelope and rotationally induced mixing. Models with overshoot and weaker interpulse mixing - as perhaps expected from more slowly rotating stars - yield larger neutron exposures. We conclude that the incorporation of rotationally induce mixing processes has important consequences for the production of heavy elements in AGB stars. Through a distribution of initial rotation rates it may lead to a natural spread in the neutron exposures obtained in AGB stars of a given mass - as appears to be required by observations. Our results suggest that both processes, diffusive overshoot and rotational mixing, may be required to obtain a consistent description of the s-process in AGB stars which fulfils all observational constraints. Finally, we find that mixing due to rotation within our current framework does increase the production of N15 in the partial mixing zone, however still falling short of what seems required by observations.

Dynamic Behavior of Laminated Glass Plates

Publisher: name: Challenging Glass Conference Proceedings

description: This paper dealt with the theoretical and experimental dynamic behaviour of laminated glass. The developments are based on the contrasted plate model (Boutin and Viverge 2016) that accounts for the high contrast of mechanical properties between the glass layers and the soft viscoelastic interlayer through the additional kinematic variable describing the sliding between the glass layers. This yields an analytic tri-Laplacian representation that encompasses (i) the shear related to the sliding within the PVB, (ii) the local bending of each glass layer, and (iii) global bending of the whole laminate. In dynamics it is shown that three types of bending waves exist, two being evanescent and one being propagating. This enables the determination of the modes of laminated glass plates submitted to different boundary conditions. The energy balance enables to assess the local dissipation of the PVB, which results in the damping of the modes. This approach is compared to vibration tests performed at temperatures ranging from 30 to 50°C. The influence of the PVB on the eigen frequencies and on the damping is clearly evidenced. A good qualitative correspondence with the theory is obtained.

description: Spatial and visual connectivity are important metrics when developing workplace layouts. Calculating those metrics in real-time can be difficult, depending on the size of the floor plan being analysed and the resolution of the analyses. This paper investigates the possibility of considerably speeding up the outcomes of such computationally intensive simulations by using machine learning to create models capable of identifying the spatial and visual connectivity potential of a space. To that end we present the entire process of investigating different machine learning models and a pipeline for training them on such task, from the incorporation of a bespoke spatial and visual connectivity analysis engine through a distributed computation pipeline, to the process of synthesizing training data and evaluating the performance of different neural networks.

НЕРАЗГАДАННЫЙ ГОГОЛЬ. Рецензия на книгу: Манн Ю.В. Н.В. Гоголь. Тайны биографии и тайны творчества. М.: РГГУ, 2019. 143 с.

description: В статье рецензируется новая книга доктора филологических наук, профессора РГГУ Ю.В. Манна, одного из авторитетнейших в мире исследователей русской литературы и особенно Гоголя. Однако для автора Гоголь остается одним из самых загадочных писателей. Такова, по мнению ученого, и репутация Гоголя в читающем мире. Его «Мертвые души» и «Нос» входят в число книг (1001 произведение), которые, по мнению современного британского исследователя, следует прочитать раньше, чем умереть, – а вместе с тем современники – соотечественники Гоголя считали его творчество понятным только для России. В этом, показывает Манн, один из парадоксов, или загадок Гоголя. Сегодня же он рассматривается Манном в мировом контексте литературоведения, прозы и философии – так можно обозначить внутренний сюжет рецензируемой книги. Соединяя историко-функциональный подход с анализом поэтики, автор показывает, как происходило восприятие гоголевского творчества в России и в мире. Здесь же намечаются и новые возможности интерпретаций произведений Гоголя. Исследуя историю вхождения Гоголя в мировую литературу, Манн касается как переводов его произведений на европейские языки, начиная с первых, так и постановок (вплоть до современных). Таким образом, выстраивается картинарецепции гоголевского художественного мира европейскими читателями / зрителями / исследователями. В западном литературоведении Гоголь, с одной стороны, занимает положение рядом с Сервантесом, а с другой –делается родоначальником литературы абсурда. Главные же тайны Гоголя, его творчества и жизни, – это второй том «Мертвых душ» и «Прощальная повесть». Автор считает, что «истоки трагедии – в эволюции Гоголя, писательской, творческой, духовной; в характере замысла ”Мертвых душ” как итоговой, главной книги; в особенностях созданной ею ситуации, личной и общественной». С одной стороны – мессианские ощущения творца, которому властью свыше дано было явить миру некую открывшуюся ему истину. С другой – намеренное подключение автором читателя к своему миру, что противоречило самому складу личности Гоголя и привело к трагическому финалу.

description: Global health is becoming increasingly relevant to GPs in the UK. A gap analysis revealed many global health capabilities are not currently in the GP curriculum. We undertook a survey of 240 GP educators to understand their views on global health and capacity to deliver global health teaching to GP trainees. This revealed a wide variation of experience, training, and confidence in global health teaching. It is important that the needs of GP trainers are taken into account when considering how global health training will be delivered

description: This paper reports on the experimental design process and considerations of a discretecontinuous choice experiment conducted in collaboration with landholders in northern Australia. The purpose of the research is to inform the design of effective and efficient payments-for-ecosystem services schemes to safeguard north Australia’s biodiversity values by promoting the contractual provision of biodiversity conservation services by landholders, in particular pastoralists and graziers. The paper focusses in particular on the discrete choice experimental (DCE) aspects. The DCE is employed to estimate landholders’ preference heterogeneity for supplying ecosystem services, specifically their willingness to accept remuneration for the on-farm conservation of biodiversity, based on potential program attributes. The design of the choice experiment draws on best practice standards (Hoyos 2010), a recognition of the benefits of embedding design in a consultative process (Klojgaard et al. 2012) and recent advances in accounting for response certainty (Brouwer et al. 2010; Hensher et al. 2012). DCE design decisions relating to attribute selection, attribute levels, alternatives and choice tasks are explained based on literature, focus group discussions, expert interviews and an iterative process of efficient DCE design. Additional design aspects include (i) a set of supplementary questions after each choice set to measure respondents’ choice certainty and elicit decision heuristics; (ii) embedding of the experiment in a socio-economic-psychological questionnaire, and (iii) logistical design.
