description: We continue the effort of defining and evaluating the quantum entropy function for supersymmetric black holes in 4d ${\cal N} = 2$ gauged supergravity, initiated in [1803.05920]. The emphasis here is on the missing steps in the previous localization analysis, mainly dealing with one-loop determinants for abelian vector multiplets and hypermultiplets on the non-compact space $\mathbb{H}_2 \times Σ_{\rm g}$ with particular boundary conditions. We use several different techniques to arrive at consistent results, which have a most direct bearing on the logarithmic correction terms to the Bekenstein-Hawking entropy of said black holes.

description: В статье представлен критический разбор понятия «модернистский рассказ», проанализированы современные тенденции в его изучении и продемонстрированы исследовательские возможности, которые открывает его расширенная трактовка. Классическое понимание английского модернистского рассказа сформировалось под влиянием короткой прозы таких авторов, как В. Вулф, К. Мэнсфилд и Дж. Джойс, и к последним десятилетиям XX в. оно оформилось в импрессионистическую концепцию жанра. Согласно данной концепции предметом изображения в модернистском рассказе является раздробленное и субъективное восприятие мира человеком, которое определяет такие ключевые черты жанра, как незначительность фабулы, повышенное внимание автора к форме выражения, использование новаторских повествовательных техник и сосредоточенность на работе сознания. В первые десятилетия XXI в. импрессионистическое понимание модернистского рассказа и перенос его характеристик на современный рассказ в целом были подвергнуты критике. Одна из ведущих тенденций новейших исследований состоит в отказе от сведения сущности модернистского рассказа к подчеркнуто новаторским в формальном отношении текстам узкого круга канонических авторов и включении в поле зрения тех рассказов, в которых рефлексия о субъективности и сознании человека в условиях исторического перелома принимает менее радикальные формы. Краткий анализ особенностей поэтики наследующих повествовательной традиции рассказов М. Синклер позволяет показать продуктивность расширенного понимания модернистского рассказа.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. 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. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

Correlation between the Mean Matter Density and the Width of the Saturated Lyman Alpha Absorption

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We report a scaling of the mean matter density with the width of the saturated Lyman alpha absorptions. This property is established using the ``pseudo-hydro'' technique (Croft et al. 1998). It provides a constraint for the inversion of the Lyman alpha forest, which encounters difficulty in the saturated region. With a Gaussian density profile and the scaling relation, a simple inversion of the simulated Lyman alpha forests shows that the one-dimensional mass power spectrum is well recovered on scales above 2 Mpc/h, or roughly k < 0.03 s/km, at z=3. The recovery underestimates the power on small scales, but improvement is possible with a more sophisticated algorithm.

description: We study the cyclical properties of sales, regular price changes and average prices paid by consumers (“effective” prices) using data on prices and quantities sold for numerous retailers across many U.S. metropolitan areas. Inflation in the effective prices paid by consumers declines significantly with higher unemployment while little change occurs in the inflation rate of prices posted by retailers. This difference reflects the reallocation of household expenditures across retailers, a feature of the data which we document and quantify, rather than sales. We propose a simple model with household store-switching and assess its implications for business cycles and policymakers.
description: Les auteurs analysent les propriétés cycliques des soldes, des variations de prix des articles non soldés et des prix moyens acquittés par les consommateurs (prix « effectifs »), à l’aide de données sur les prix et les quantités vendues provenant d’un grand nombre de détaillants dans de nombreuses agglomérations américaines. Ils observent qu’en ce qui a trait aux prix effectifs réglés par le consommateur, l’inflation diminue sensiblement lorsque le chômage augmente, alors que pour ce qui est des prix affichés dans les commerces, l’inflation varie peu. Cette différence tient moins aux soldes qu’à la réaffectation des dépenses des ménages entre les détaillants, caractéristique que les données recueillies permettent d’étayer et de quantifier. Les auteurs présentent un modèle simple dans lequel les ménages changent de magasin, et évaluent les implications de ces mouvements pour les cycles économiques et la politique monétaire.
TRANSLINGUALISM IN THE LIGHT OF SEMIOTICS (“Maybe Esther” by Katja Petrowskaja)
Creators: name: Бакши Наталия Александровна
Publisher: name: Новый филологический вестник
Year: 2021
Subjects: translingualism; Katja Petrowskaja; World War II; semiotic; Lotman; cultural memory

description: Translingualism emerged during the 2000s as a new concept, alongside polylingualism and metrolingualism, that is clearly distinct from the guiding concept of multilingualism. The concept relativizes rigid connections between language, people and territory on the one hand, whilst also calling into question the notion of languages as closed and clearly distinguishable units. It is predicated upon “dynamic bilingualism”, whereby the languages involved each represent their own respective system. Translingualism thus brings a new aspect of linguistic reflexion into play. Thus understood, translingualism will be explicated in relation to Katja Petrowskaja’s novel. The German author of Ukrainian extraction was awarded the Ingeborg-Bachmann-Prize in 2014 for her debut work “Maybe Esther” in which she describes, in a language that is foreign to her, the story of her family during the World War II, in the course of which a number of her Jewish relatives were murdered. For the purposes of the current paper, the prime interest is not the content of this quite typical 20th century story, but its linguistic conception. Petrowskaja is a professional philologist who graduated from the University of Tartu and its renowned semiotic school led by Jurij Lotman and Boris Uspenskij. Her text is deliberately constructed according to semiotic principles and can be read as a literary demonstration of Lotman and Uspenskij’s academic concepts. Behind the linguistic peculiarities, a hidden semiotic approach to language is evident, which regards language as a system of symbols. Translingualism in Petrowskaja’s writing, which purports to transcend linguistic boundaries by mixing languages and crossing over associatively from one language to the other, does not in fact dissolve linguistic boundaries. Rather, it activated reflexive processes across such boundaries. In the light of Lotman’s work on culture and cultural memory, Petrowskaja’s novel appears not only as a linguistic experiment but also, above all, as an experiment in engaging with diverse cultural codes. The translingual aspect illustrates the reflexion across apparently different and historically unconnected languages and cultures. On the other hand, the concept also contains a conscious denial of power structure associated with to the monolingualism of a national language.
Angular ordering effects in TMD parton distribution functions and Drell-Yan $q_{\bot}$ spectra

description: We present new results of our studies of soft-gluon angular ordering effects on the evolution of both collinear and transverse momentum dependent (TMD) parton distribution functions, and discuss their implications for precision predictions of Drell-Yan transverse momentum spectra at the LHC. Our method is based on the parton branching (PB) approach. We compare this with the implementation of angular ordering in the Kimber-Martin-Ryskin-Watt (KMRW) approach and with the Collins-Soper-Sterman (CSS) approach. We illustrate numerically the effects of different ordering scenarios ($p_{\bot}$, angular ordering), including definitions of the soft-gluon resolution scale and scale in the running coupling, on the theoretical accuracy of predictions in the low transverse momentum region of Drell-Yan spectra measured at the LHC.

Seasonality of Diesel Fuel Prices
Creators: name: Ibendahl, Gregg

Publisher: name: Unknown
Year: 2012
Subjects: Farm Management

description: Diesel fuel is a major expense for most farmers. Diesel fuel prices do exhibit some seasonality so farmers can try to lower their fuel expenses by buying their fuel in months when prices are lower. However, purchasing fuel before it is needed results in a carrying charge to the farmer. This paper examines the optimal purchase month for diesel fuel for both spring planting and fall harvest. Both risk neutral and risk-averse farmers are considered. Higher interest rates discourage advance purchasing, but in many cases farmers would be better served by purchasing diesel in advance of use.
Investigating the origin of breakage of panes subjected to blast loading by acoustic emission testing
Creators: name: Van Der Woerd, Jan Dirk
Publisher: name: Challenging Glass Conference Proceedings
Year: 2020

description: The Fraunhofer EMI shock-tube facility “Blast-STAR” is used to simulate blast loadings from high explosive detonations similar to realistic conditions. Mainly tests on explosion-resistant safety glazing and façades are carried out. Due to the extreme conditions during the test, it is not trivial to accurately analyze the specimen reaction and in particular to determine the start of breakage of the glass pane. Usually high-speed footage is used for this purpose. Since the size of tested elements is increasing, the determination of place and time of breakage becomes more challenging. Monk and Clubley successfully used piezo transducers in an alternative approach to measure the shock wave originating from glass breakage for detecting the point of initial cracking. They used long-duration blasts, characterized by small peak pressures and a long positive phase duration. In contrast, the blast waves generated with the “Blast-STAR” are characterized by higher peak pressures and a considerable shorter positive phase. The presented work examines the applicability of the approach for the “Blast-STAR” experiments and the accuracy compared to video recordings. Within the paper five shock tube tests are described and evaluated. The results and the experimental set-up are discussed and an outlook for further research is given.

ВОЗВРАЩЕНИЕ ИЗ ССЫЛКИ: ОПЫТ ПАНКРАТИЯ СУМАРОКОВА

description: В статье впервые на основе документальных и литературно-художественных произведений 1801–1810-х гг. реконструируется опыт возвращения из ссылки поэта, переводчика, редактора П.П. Сумарокова, находившегося в Сибири четырнадцать лет (1787–1801). Возвращение из ссылки понимается как лиминальная ситуация, биографическое событие и система мотивов. Исследование построено на сравнительном анализе системы мотивов возвращения из ссылки в документе «Прошение Панкратия Платоновича Сумарокова на Высочайшее имя о восстановлении его в сословных и имущественных правах» (1801) и литературно-художественных произведениях писателя. Методология исследования является интегративной: мотивный анализ текстов возвращения сосуществует с биографическим анализом, а также с методикой интерпретации обрядов перехода А. ван Геннепа. Показано, что ссылка в текстах возвращения связана с мотивами дома как внешнего и внутреннего пространства жизни; страдания / слез / травмы, а также с ситуацией «творчество как спасение», в основании которой – библиофилический культурный миф эпохи Просвещения. Сюжет возвращения из ссылки представлен тремя основными мотивами: дома (утраты сибирского и создания нового в родовом имении), превращения (метаморфоз), обновления / новизны. Установлено, что «включение» в новый порядок жизни после возвращения было для Сумарокова не только воссозданием тех форм творчества (журналы, переводные повести, стихотворения, домостроительные книги), которыми он занимался в Сибири, но и критическим переосмыслением библиофилического культурного мифа: в лиминальной ситуации «между книгами и жизнью» творчество жизни становится для него важнее сочинения книг.

description: Although Weyl semimetals have been extensively studied for exploring rich topological physics, the direct observation of the celebrated chiral magnetic effect (CME) associated with the so-called dipolar chiral anomaly has long intrigued and challenged physicists, still remaining elusive in nature. Here we propose a feasible scheme for experimental implementation of ultracold atoms that may enable us to probe the CME with a pure topological current in an artificial Weyl semimetal. The paired Weyl points with the dipolar chiral anomaly emerge in the presence of the well-designed spin-orbital coupling and laser-assisted tunneling. Both of the two artificial fields are readily realizable and highly tunable via current optical techniques using ultracold atoms trapped in three-dimensional optical lattices, providing a reliable way for manipulating Weyl points in the momentum-energy space. By applying a weak artificial magnetic field, the system processes an auxiliary current originated from the topology of a paired Weyl points, namely, the pure CME current. This topological current can be extracted from measuring the center-of-mass motion of ultracold atoms, which may pave the way to directly and unambiguously observe the CME in experiments.

title: A New Linear Estimator for Gaussian Dynamic Term Structure Models
Creators: name: Diez de los Rios, Antonio
Publisher: name: Bank of Canada
Year: 2013

description: This paper proposes a novel regression-based approach to the estimation of Gaussian dynamic term structure models that avoids numerical optimization. This new estimator is an asymptotic least squares estimator defined by the no-arbitrage conditions upon which these models are built. We discuss some efficiency considerations of this estimator, and show that it is asymptotically equivalent to maximum likelihood estimation. Further, we note that our estimator remains easy-to-compute and asymptotically efficient in a variety of situations in which other recently proposed approaches lose their tractability. We provide an empirical application in the context of the Canadian bond market.
description: Un cadre de régression novateur permettant d’éviter l’optimisation numérique est proposé pour l’estimation de modèles dynamiques gaussiens de la structure par terme des taux d’intérêt. Ce nouvel estimateur est un estimateur des moindres carrés asymptotiques et est défini par les conditions d’absence d’arbitrage à la base de ces modèles. L’auteur analyse les caractéristiques d’efficience de son estimateur et montre que celui-ci est asymptotiquement équivalent à un estimateur du maximum de vraisemblance. De plus, il reste simple à calculer et asymptotiquement efficient dans un éventail de situations où d’autres approches récentes deviennent très difficiles à utiliser. L’auteur présente une application empirique de son cadre au cas du marché obligataire canadien.

description: В статье изучаются сюжетные роли Вернера, одного из ключевых персонажей «Княжны Мери». Автор стремится выяснить, как эти роли определяют способы и формы участия Вернера в сюжетных событиях. Специальный анализ позволяет понять их значение для развития действия. Автор подробно рассматривает роли доктора и приятеля, которые выполняет Вернер в разных эпизодах, и показывает, как в сюжетно значимых ситуациях эти роли совмещаются. Вернер, как доказывает автор, не просто доктор, т.е. персонаж, обладающий определенным профессиональным статусом, но курортный доктор. Печорин вовлекает Вернера в интригу, чтобы использовать возможности доктора узнавать и сообщать ему о циркулирующих на курорте слухах и новостях, а также об интересующих его пациентах. Нарушение доктором врачебной тайны, когда он делится с Печориным сведениями о состоянии здоровья и личной жизни пациентов, свидетельствует о его нравственном релятивизме. Вернер предстает в повести не только как курортный доктор, но и как курортный Мефистофель, напоминающий внешним обликом и речевым поведением героя Гёте. С прозвищем, данным ему молодежью, соотносятся окружающие его фигуру демонические коннотации. Прозвище выделяет его из курортной толпы, но не уподобляет духу отрицания. Печорин отмечает способность Вернера к высоким движениям души. В основе взаимной симпатии Печорина и Вернера, ставших приятелями, лежит не эмоциональная близость и не общность интересов, а сознание собственной исключительности. Себя и Вернера Печорин, следуя универсальной романтической антитезе, причисляет к избранным, противостоящим непосвященной толпе. Однако, манипулируя всеми, с кем он встречается, Печорин не делает исключение и для Вернера. В комедии, режиссером которой выступает Печорин, Вернер должен играть по предложенным им правилам. Но ее развязка служит для Вернера знаком исчерпанности приятельских отношений. Роли доктора и приятеля, как доказывает автор, сужают границы личности Вернера, для которого этические категории сохраняют свое абсолютное значение.

description: The study examined resource productivity analysis of small scale root and tuber crop farmers in Niger State, Nigeria. Data used for the study were obtained from primary source using a multi-stage sampling technique with structured questionnaires administered to 150 randomly selected root and tuber crop farmers from the study area. Descriptive statistics such as means, standard deviations, frequency distribution table and percentages were used to summarize the variables used in the analysis while data envelopment analysis was used to empirically determine the resource productivity in the study area. The DEA result on the overall technical efficiency of the farmers showed that 6% of the sampled root and tuber crop farmers in the study area were operating at frontier and optimum level of production with mean technical efficiency of 1.00. Decomposition of technical efficiency also showed mean efficiency scores of 0.25 and 0.32 for overall technical efficiency and scale efficiency respectively meaning that, on average, the sampled farms were more scale efficient than they are technically efficient. The study further revealed that most of the farms could reduce total expenditures on the farm land, labour, planting material, agrochemical, fertilizer and capital inputs by 8.17%, 5.17%, 29.53%, 23.71%, 0.09% and 10.08%, respectively without reducing their current level of production. The study therefore recommended that root and tuber crop farmers in the study area should form cooperative societies so as to enable them have access to productive inputs that will enable them expand. This will as well increase efficiency of resource utilization. Also, since few farms were robustly efficient, the farmers in the study area, enhanced research, extension delivery and farm advisory services should be put in place for farmers to learn the best farm practices carried out on the robustly efficient farms. This will go a long way to increase the efficiency level of the farmers in the study area.

The Application of Waste Float Glass, Recycled in Structural Beams made with the Glass Casting Method
Creators: name: Yu, Rong
Publisher: name: Challenging Glass Conference Proceedings
Year: 2020

description: It is not obvious to talk about glass recycling when we realize that a mature recycling procedure for glass bottles is already working well. However, apart from glass bottles, unfortunately, that a large amount of glass will disappear into landfills. This large quantity of unrecycled glass indicates that there is a large potential in upgrading the glass recycling process. In the field of architecture, we see a fast-growing interest in using glass, also for structures. The glass bricks of Crystal Houses in Amsterdam are a good illustration. Aiming at maximizing the recyclability of glass, this paper focuses on the structural use of the glass components made from recycled glass through kiln casting method. An overview of the existing glass recycling industry is given at the beginning, followed by a discussion of glass type to be recycled. After this the experimental process of the glass recycling is introduced, which uses coated float glass with tints as the basic material to be recycled. Following this, a further exploration in three structural properties of the recycled products is conducted, namely: Young’s modulus, coefficient of thermal expansion and the fracture strength, with mechanical experiments. Finally, the test results are analyzed together with the chemical composition of the recycled products, which is derived from X-ray fluorescence (XRF) analysis. The result contains the value of mechanical properties and it evaluates the possibility of the structural use as a recycled-float-glass beam. In the end of this paper, the future possibility and feasibility in structural application of recycling waste float glass are discussed.

Year: 2013

description: A longstanding finding in the forecasting literature is that averaging forecasts from different models often improves upon forecasts based on a single model, with equal weight averaging working particularly well. This paper analyzes the effects of trimming the set of models prior to averaging. We compare different trimming schemes and propose a new one based on Model Confidence Sets that take into account the statistical significance of historical out-of-sample forecasting performance. In an empirical application of forecasting U.S. macroeconomic indicators, we find significant gains in out-of-sample forecast accuracy from our proposed trimming method.
description: Les études consacrées au travail de prévision ont fait ressortir depuis longtemps que la moyenne des projections de plusieurs modèles a souvent un degré de précision plus élevé que les projections tirées d’un seul modèle, et qu’à ce titre, la technique qui consiste à établir une moyenne en pondérant les prévisions avec les mêmes coefficients donne de très bons résultats. Les auteurs se demandent ce qu’apporterait l’élagage de modèles avant le calcul des projections moyennes. À cette fin, ils comparent différentes méthodes d’élagage et proposent une nouvelle démarche (Model Confidence Set ou approche MCS) fondée sur la sélection de modèles selon un seuil de confiance défini par la valeur statistique de la qualité passée des prévisions hors échantillon. Un exercice empirique - la projection d’indicateurs macroéconomiques pour les États-Unis - leur permet de constater que leur démarche améliore de manière notable la précision des prévisions hors échantillon.

description: Improving smallholder farmer market participation (agricultural commercialization) has seen the advent of a number of initiatives from collective action, extension service provision and even programs that utilize ICT tools in the provision of market information. Collective action through farmer groups is an important social asset for smallholders that continue to face challenges in accessing both input and output markets. The objective of this study was to assess the effect of participation in collective action initiatives on household agricultural commercialization (market access) and household agricultural income. The study utilizes propensity score matching technique to assess the effect of collective action initiatives on household agricultural commercialization and on household agricultural income. Results indicate that farmers participate in collective action initiatives for good reasons which include enhanced access to markets and improvement of their incomes. This study brings into perspective the effects of participation in collective action initiatives both on market participation and on smallholder incomes. It finds that participation in collective action initiatives significantly increase household output and input market participation by about 9 percent and 8 per cent respectively. It also improve household welfare by increasing incomes (by about Ksh. 3400 per growing season). We discuss implications for policy and practice.
title: Jump-Diffusion Long-Run Risks Models, Variance Risk Premium and Volatility Dynamics
Creators: name: Jin, Jianjian
Publisher: name: Bank of Canada
Year: 2013

description: This paper calibrates a class of jump-diffusion long-run risks (LRR) models to quantify how well they can jointly explain the equity risk premium and the variance risk premium in the U.S. financial markets, and whether they can generate realistic dynamics of risk-neutral and realized volatilities. I provide evidence that the jump risk in volatility of long run consumption growth is a key component of the equity risk premium and the variance risk premium in financial markets. Moreover, I find that matching the VIX dynamics during the calibration process is crucial when comparing different jump channels. Specifically, a jump-in-growth LRR model generates a good fit of the average variance risk premium, but a poor fit of the dynamics of the VIX or realized stock volatility. In contrast, a jump-in-volatility LRR model generates a smaller variance risk premium but better fits the VIX and the realized stock volatility dynamics. Finally, jump-in-volatility models generate predictability of returns by the variance risk premium that is more consistent with the data.
description: L’auteur calibre une classe de modèles de diffusion avec sauts et risques de long terme, afin d’évaluer leur aptitude à générer les primes de risque sur actions et de risque de variance observées dans les marchés financiers américains et des dynamiques des volatilités réalisée et risque-neutre reflétant la réalité. Il démontre que le risque de saut associé à la volatilité de la croissance de la consommation à long terme est une composante clé de ces deux primes. L’auteur constate par ailleurs que reproduire les évolutions de l’indice VIX durant le processus de calibrage est un aspect indispensable de la comparaison des différentes sources de sauts. Plus précisément, les modèles avec sauts dans la croissance anticipée de la consommation répliquent assez bien la prime moyenne liée au risque de variance mais plutôt mal l’évolution de l’indice VIX et de la volatilité réalisée du marché des actions. À l’opposé, les modèles avec sauts dans la volatilité génèrent une prime de risque de variance inférieure à la véritable prime, mais ils reproduisent mieux la dynamique de l’indice VIX et de la volatilité réalisée du marché des actions. Enfin, cette seconde catégorie de modèles explique mieux la capacité de la prime de risque de variance à prédire les rendements du marché des actions, telle qu’elle ressort des données empiriques.

description: Compared to urban regions, rural areas can be seen as historicaly marginal space. They, as a rule, leve behind in the process of participation in general developmental trends, mainly due to lack of local capital stock and personalities. Marginality, however, is a context dependet phenomenon and some of its formating features can be converted into factors local development can be based on. The process of commodification of 'non-marginal parameters' may, in the end, lead to opening of rural areas to general trends of globalisation. Embedding of rural areas into global context raises at least one question - what is the role of local communities in decision making proces on future development of a region or locality they live in? Should such a decision be taken primarily on local level or is the future of a particular locality predetermined by decisions taken on national or even international levels? In this context, the article disusses problem of distribution of power in decision making process between local community and representatives of 'external force' by use of empirical evidence taken from two examples -blocking of foreign investment aimed at building of huge leisure park in pristine landscape of South Bohemia, and long term clashes between Sumava national park administration and local communities.
КОРАНИЧЕСКИЕ МОТИВЫ В РУССКОЙ ПОЭЗИИ XIX В.

description: Целью данной статьи является попытка исследовать коранические мотивы и образы в творчестве ряда русских поэтов, таких как Лукьян Якубович (1805–1839), Яков Полонский (1819–1898), Николай Греков (1807–1866), Михаил Михайлов (1829–1862) и Лев Кобылинский-Эллис (1879–1947). Анализируя вопрос заимствования содержания аятов Корана и интерпретации их смысла как способа выражения коранических мотивов в творчестве отмеченных поэтов, автор статьи выявляет точное следование стихов кораническому смыслу и коннотации. Методология работы определяется теорией системно-комплексного подхода к изучаемому материалу, позволяющего рассматривать определенные стихотворения указанных поэтов как образец ориентальной поэзии с ярко выраженной коранической тематикой. Новизна исследования заключается в том, что в нем предпринята попытка детального анализа коранической тематики в восточной лирике названных поэтов, чьи отдельные сочинения на коранические темы не введены в научный оборот, недостаточно разработаны в критике и остаются малоисследованными. Автор статьи приходит к выводу, что в творчестве русских поэтов, чьи стихотворения служили объектом анализа в настоящей статье, кораническая литература сыграла важную роль.

description: The authors use the Financial Stress Index created by the International Monetary Fund to predict the likelihood of financial stress events for five developed countries: Canada, France, Germany, the United Kingdom and the United States. They use a semiparametric panel data model with nonparametric specification of the link functions and linear index function. The empirical results show that the semiparametric early warning model captures some well-known financial stress events. For Canada, Germany, the United Kingdom and the United States, the semiparametric model can provide much better out-of-sample predicted probabilities than the logit model for the time period from 2007Q2 to 2010Q2, while for France, the logit model provides better performance for non-financial stress events than the semiparametric model.
description: Les auteurs s’appuient sur l’indice de tension financière créé par le Fonds monétaire international afin de prévoir le risque de matérialisation de tensions financières dans cinq pays développés : l’Allemagne, le Canada, les États-Unis, la France et le Royaume-Uni. Ils utilisent un modèle semi-paramétrique avec données sur panel et spécification non paramétrique de fonctions de lien et d’une fonction linéaire indicielle. Les résultats empiriques montrent que le prédicteur avancé constitué par leur modèle restitue des épisodes bien connus de tensions financières. Dans le cas de l’Allemagne, du Canada, des États-Unis et du Royaume-Uni, le modèle semi-paramétrique peut fournir des prévisions des probabilités hors échantillon qui sont de qualité nettement supérieure à celles du modèle logit pour la période comprise entre le 2e trimestre de 2007 et le 2e trimestre de 2010. Pour la France, le modèle logit produit de meilleures prévisions des tensions non financières que le modèle semi-paramétrique.
Experimental Analysis of Laminated Embedded Steel Insert in Load Bearing Connections

Publisher: name: Challenging Glass Conference Proceedings

description: Use of glass as a load bearing structural elements has increased significantly in last years. The glass is brittle material, which behaves elastically until brittle failure which occurs suddenly without any warning. Therefore, special emphasis shell be devoted to the connections with load bearing role. Their inappropriate design can lead to local peaks of stress or eccentricity of the connections and the generation of additional moments, resulting in a reduction of the load-bearing capacity. Currently, mechanical (clamped, friction-grip and bolted connections) or adhesive joints are commonly used, the latter being characterized by a more uniformly distributed stress along the connection and the undisturbed surface of the glass panels. The disadvantage of polymeric adhesives is however the sensitivity of the load-bearing capacity to the ageing, technology of the production - the proper cleaning of the surfaces as well as the application of adhesive, UV stability during the lifetime etc. Although, there is still a lack of information about all aspects of the adhesive behaviour in the load bearing joint, their use in structural applications is considered very promising. In the last years, a novel typology of enhanced adhesive connections, known as laminated adhesive connection, has been developed. These connections are formed during the lamination process of the laminated glass fabrication and they are characterized by transparency and high aesthetic appearance especially when the size of the laminated metal insert is limited. Paper is focused on the experimental investigation of novel embedded laminated connection with thick steel plate and built-in internal thread pre-prepared for common bolts, used to assembly glass element to another one, or directly to the steel or concrete substructure. Mechanical behaviour of this connection is main goal of the research. Small scale test specimens were tested to obtain mechanical behaviour of the connection. Embedded stainless steel plate in laminated glass is in vertical position and enables connection between the glass cantilever beam and supporting structure. The specimens were loaded until maximum strength of connection was reached.

description: This paper discusses the challenges that the next EU programming period has given to rural policy. In the case of Finland the most important level of implementing regional and rural policies so far has been provinces (NUTS 3) but in 2007—2013 both the EU Commission and our national rural policy highlight the role of sub-regions (NUTS 4). The schedule of preparation of regional rural programmes has been very tight in Finland, which was due to both too late and inappropriate instructions from the Ministry of Agriculture and Forestry and to some changes in the organizations, which were responsible for the preparation. Our case study area, Raahe sub--region, is especially interesting since there were two rural development actors with almost the same aims but with quite different backgrounds. The problems in the creation of cooperation between them were connected e.g. to inadequate social capital and to the operation areas. The empirical part of the paper describes what kind of challenges and tensions different actors faced when preparing a rural development programme on the sub-regional level.
