In this paper, a shear stiffness model for corrugated-core sandwich structures is proposed. The bonding area is discussed independently. The core is thought to be hinged on the skins with torsional stiffness. The analytical model was verified by FEM solution. Compared with the previous studies, the new model can predict the valley point of the shear stiffness at which the relationship between the shear stiffness and the angle of the core changes from negative correlation to positive correlation. The valley point increases when the core becomes stronger. For the structure with a angle of the core smaller than counterpart for the valley point, the existing analytical formulations may significantly underestimate the shear stiffness of the structure with strong skins. The results obtained by some previous models may be only 10 persent of that of the present model, which is supported by the FEM model.

In his article, A. Zholkovsky discusses the contemporary detective mini-series Otlichnitsa [A Straight-A Student], which mentions O. Mandelstam’s poem for children A Galosh [Kalosha]: more than a fleeting mention, this poem prompts the characters and viewers alike to solve the mystery of its authorship. According to the show’s plot, the fact that Mandelstam penned the poem surfaces when one of the female characters confesses her involvement in his arrest. Examining this episode, Zholkovsky seeks structural parallels with the show in V. Aksyonov’s Overstocked Packaging Barrels [Zatovarennaya bochkotara] and even in B. Pasternak’s Doctor Zhivago [Doktor Zhivago]: in each of those, a member of the Soviet intelligentsia who has developed a real fascination with some unique but unattainable object is shocked to realize that the establishment have long enjoyed this exotic object without restrictions. We observe, therefore, a typical solution to the core problem of the Soviet, and more broadly, Russian cultural-political situation: the relationship between the intelligentsia and the state, and the resolution is not a confrontation, but reconciliation.

В статье исследуются события бескоролевья 1733 г. в Речи Посполитой. Согласно «трактату Левенвольде» компромиссным кандидатом на избрание монархом Речи Посполитой был португальский инфант дон Мануэль, которого предложила Австрия. Россия больше склонялась к кандидатуре «пяста». Россия оказалась не подготовленной к началу бескоролевья. Бывшие российские союзники магнаты ВКЛ рассорились с российским послом Фридрихом Казимиром Левенвольде и перешли на сторону Франции. В конце февраля 1733 г. в ВКЛ направили Юрия Ливена, который от имени российской царицы предложил поддержку в получении короны Михаилу Вишневецкому и Павлу Сангушке. Принятое на конвокационном сейме решение об избрании королем «пяста» и католика показало популярность Станислава Лещинского. В результате вслед за Австрией Россия поддержала кандидатом на корону Фридриха Августа. Магнаты ВКЛ до последнего оставались конкурентами о короне. Оппозиция Лещинскому объединилась под лозунгом защиты «вольного выбора» и поэтому в ней остались кандидаты «пясты», которые не могли уступить друг другу, и согласились на компромисс – кандидатуру Фридриха Августа. Для противодействия возможному избранию Лещинского Россия создала в ВКЛ новоградскую конфедерацию. Ее организатором стал новоградский воевода Николай Фаустин Радзивилл. Эта конфедерация становится основой Генеральной Варшавской конфедерации, которая 5 октября 1733 г. избирает королем саксонского курфюрста. The article examines the events of the «kingless» year of 1733 in the Polish-Lithuanian Commonwealth. According to the Levenwolde Treaties the compromise candidate for the Commonwealth’s throne was the Portuguese Infante Don Manuel, who’s candidacy was proposed by Austria. Russia, in turn, leaned towards the «pyasta» candidate. The Russian Empire was clearly unprepared for the start of the kingless period. Russia’s former allies – magnates of the Grand Duchy of Lithuania – came into conflict with the Russian ambassador Frederick Kazimir Levenwolde and sided with France. In late February of 1733, Empress Anna Ioanovna of Russia sent Yuri Liven to the Grand Duchy of Lithuania, who offered official support in the struggle for the crown to Mikhail Vishnevetsky and Pavel Sangushka. The electoral decision made at the Sejm proved the popularity of the «pyast» and Catholic candidates, specifically – Stanislaus Leschinsky. In turn, Russia – following Austria – showed its support for the candidacy of Frederick August. The magnates of the Grand Duchy of Lithuania remained in opposition in the crown issue until the very last. Opposition to Leschinsky was united under the motto of «free choice». For that reason, it was comprised of «pyasta» candidates, who were in a deadlock with one another, and were now ready for the compromise candidacy of Frederick Augustus. In order to counter the possible election of Leschinsky, Russia created the Novograd Confederation in the Grand Duchy of Lithuania. It was organized by the Novograd Voevoda Faustin Radzivill. This confederation became the core of the General Warsaw Confederation that – on October 5th 1733 – elected the Saxon King to the throne of the Polish-Lithuanian Commonwealth.

This volume revisits the debates and disputes known collectively in the literature on late sixteenth- and early seventeenth-century England as the ‘Archpriest Controversy’. We argue that this was an extraordinary instance of the conduct of contemporary public politics and that, in its apparent strangeness, it is in fact a guide to the ways in which contemporaries negotiated the unstable later Reformation settlement in England. The published texts which form the core of the arguments involved in this debate survive, as do several caches of manuscript material generated by the dispute. Together they tell us a good deal about the aspirations of the writers and the networks that they inhabited. They also allow us to retell the progress of the dispute both as a narrative and as an instance of contemporary public argument about topics such as the increasingly imminent royal succession, late Elizabethan puritanism, and the function of episcopacy. Our contention is that, if one takes this material seriously, it is very hard to sustain standard accounts of the accession of James VI in England as part of an almost seamless continuity of royal government, contextualized by a virtually untroubled and consensus-based Protestant account of the relationship between Church and State. Nor is it possible to maintain that by the end of Elizabeth’s reign the fraction of the national Church, separatist and otherwise, which regarded itself or was regarded by others as Catholic had been driven into irrelevance.

Abstract This practice report describes how Chinese meditators understand the “four foundations of mindfulness” (satipaṭṭhāna, sinianzhu 四念住) as a remedy for both mental and physical suffering. In the tradition of Theravāda Buddhism, satipaṭṭhāna is particularly recognized as the core knowledge for understanding the relationship between mind and body, and the core practice leading to liberation from suffering. Based on interviews with Chinese meditation practitioners, this study develops three main themes concerning how they have alleviated afflictions through the practice of satipaṭṭhāna. The first theme highlights how practitioners learn to overcome meditation difficulties with “right attitude.” The second theme is about practicing awareness with “six sense doors” open in order to facilitate the balance of the “five faculties.” The third theme explores how practitioners cultivate daily life practice through an understanding of the nature of mind and body as impermanent and as not-self. This paper details how these themes and embodied practices of satipaṭṭhāna constitute ways of self-healing for urban educated Buddhists in the contemporary Chinese context.

No matter how fascinating the discoveries in the field of molecular biology are, in the end it is the phenotype that matters. In this paper we pay attention to various aspects of plant phenotyping. The challenges to unravel the relationship between genotype and phenotype are discussed, as well as the case where ‘plants do not have a phenotype’. More emphasis has to be placed on automation to match the increased output in the molecular sciences with analysis of relevant traits under laboratory, greenhouse and field conditions. Currently, non-destructive measurements with cameras are becoming widely used to assess plant structural properties, but a wider range of non-invasive approaches and evaluation tools has to be developed to combine physiologically meaningful data with structural information of plants. Another field requiring major progress is the handling and processing of data. A better e-infrastructure will enable easier establishment of links between phenotypic traits and genetic data. In the final part of this paper we briefly introduce the range of contributions that form the core of a special issue of this journal on plant phenotyping.

This article concerns the relationship between policy and voter elasticity on either side of the political spectrum as an explanation of the left's post-war political failure. The core contention is that left-oriented voters are more responsive to slight deviations in policy. This is used to explain partially Labour's post-war failure to dominate power even when the ‘left's vote’ was over 50 per cent.

Abstract This article analyzes the relationship between the core concepts of disability policy and the three generations of inclusive practices. Specifically, we review the three generations of inclusive practice, highlighting the core concepts that have been most strongly emphasized during each generation of inclusive practices. Because we are early in the third generation of inclusive practices, we conclude by examining how the core concepts can guide and direct third generation inclusive practices and how future research, policy, and practice can actualize the aspirational values of all of the core concepts to enable desired outcomes.

Background. The present study investigated whether a failure of self-monitoring contributes to core syndromes of schizophrenia.Method. Three groups of patients with a DSM-IV diagnosis of schizophrenia (n=27), with either prominent paranoid hallucinatory or disorganization syndrome, or without these symptoms, and a matched healthy control group (n=23) drew circles on a writing pad connected to a PC monitor. Subjects were instructed to continuously monitor the relationship between their hand movements and their visual consequences. They were asked to detect gain changes in the mapping. Self-monitoring ability and the ability to automatically correct movements were assessed.Results. Patients with either paranoid-hallucinatory syndrome or formal thought disorder were selectively impaired in their ability to detect a mismatch between a self-generated movement and its consequences, but not impaired in their ability to automatically compensate for the gain change.Conclusions. These results support the claim that a failure of self-monitoring may underlie the core symptoms of schizophrenia.


This volume offers an overview of current research on grammatical number in language. The chapters Part i of the handbook present foundational notions in the study of grammatical number covering the semantic analyses of plurality, the mass–count distinction, the relationship between number and quantity expressions and the mental representation of number and individuation. The core instance of grammatical number is marking for number distinctions in nominal expressions as in English the book/the books and the chapters in Part ii, Number in the nominal domain, explore morphological, semantic, and syntactic aspects of number marking within noun phrases. The contributions examine morphological marking of number the relationship between syntax and nominal number marking, and the interactions between numeral classifiers with semantic number and number marking. They also address cases of mismatches in form and meaning with respect to number displayed by lexical plurals and collective nouns. The final chapter reviews nominal number processing from the perspective of language pathologies. While number marking on nouns has been the focus of most research on number, number distinctions can also be found in the event domain. Part iii, Number in the event domain, presents an overview of different linguistic means of expressing plurality in the event domain, covering verbal plurality marking, pluractional modifiers of the form Noun preposition Noun, frequency adjectives and dependent indefinites. Part iv provides fifteen case studies examining different aspects of grammatical number marking in a range of typologically diverse languages.

This article presents some considerations into metaphor in language and thought- 'the topic and title of the first conference of its kind in Brazil'. The paper focuses on the discussions presented in the round table, which were mostly directed to the empirical research on metaphor in Applied Linguistics. This integrative and retrospective reflection on the papers presented will be conducted from the perspective of the debate into the relationship between metaphor in language and in thought. This central issue is at the core of my proposal for four different approaches to metaphor, based on the interdependence between language and thought as system and as use:1) metaphor in language as system; 2) metaphor in thought as system; 3) metaphor in language as use and 4) metaphor in thought as use. It is within the framework of these categories that metaphors should be studied, with a certain degree of autonomy, so that their interdependence can be better understood.
