Alternative Questions with "or not" (NAQ) convey a cornering effect, which is not found with they polar counterparts (PQ). This effect has been claimed to consist of two parts (Biezma 2009): NAQs (i) cannot be used discourse-initially and (ii) they do not license followup questions/subquestions.
In this paper, we ask the following: Are both parts of cornering linked to the same property of NAQs? Or do they reflect distinct linguistic phenomena? We explore the issue by comparing the behavior of NAQs to Complement Alternative Questions (CAQ), a type of question that, like NAQs, presents logically opposite alternatives but, unlike NAQs, fully spells out the second one. Results from two experiments suggest that both parts of cornering can instead be explained in terms of independent semantic and pragmatic principles, which operate beyond the domain of alternative questions.
Sentences containing subjective predicates - e.g., "The movie was awesome"” - are intuitively anchored to a particular perspective; this makes them different from sentences describing objective facts - e.g., "The movie was set in 1995".
While authors have long debated on whether this intuition tracks a lexical distinction between subjective and factual predicates, much remains to be explored on whether, and how, the difference between these two assertions is reflected at the illocutionary level. Relying on evidence from two experiments, we show that assertions containing subjective predicates display different discourse behavior from objective assertions. We take these findings to support the idea that SAs should be assigned a special illocutionary profile, unveiling a genuine empirical difference between subjective and factual speech.
This paper analyses whether the post-crisis regulatory reforms developed by global-standard-setting bodies have created appropriate incentives for different types of market participants to centrally clear Over-The-Counter (OTC) derivative contracts. Beyond documenting the observed facts, we analyze four main drivers for the decision to clear: 1) the liquidity and riskiness of the reference entity; 2) the credit risk of the counterparty; 3) the clearing member’s portfolio net exposure with the Central Counterparty Clearing House (CCP) and 4) post trade transparency. We use confidential European trade repository data on single-name Sovereign Credit Derivative Swap (CDS) transactions, and show that for all the transactions reported in 2016 on Italian, German and French Sovereign CDS 48% were centrally cleared, 42% were not cleared despite being eligible for central clearing, while 9% of the contracts were not clearable because they did not satisfy certain CCP clearing criteria. However, there is a large difference between CCP clearing members that clear about 53% of their transactions and non-clearing members, even those that are subject to counterparty risk capital requirements, that almost never clear their trades. Moreover, we find that diverse factors explain clearing members’ decision to clear different CDS contracts: for Italian CDS, counterparty credit risk exposures matter most for the decision to clear, while for French and German CDS, margin costs are the most important factor for the decision. Clearing members use clearing to reduce their exposures to the CCP and largely clear contracts when at least one of the traders has a high counterparty credit risk.
In December 1965, in a smoke-filled hotel room in Morocco, South African journalist Terry Bell accepted a challenge: to paddle a kayak from London to Tangier. At the time, Terry and his wife Barbara were living as political exiles in London. By August 1967, they agreed it was time to get back to Africa. But they decided to up the ante. Their plan: paddle 11 000 kilometres from England to Dar es Salaam in a 5-metre glass fibre kayak.
A rare flowering event in a stand of Acacia pendula (Weeping Myall) (family Fabaceae, Mimosoideae) from the Hunter Valley of New South Wales is documented. This species flowers poorly in the region and (with the exception of horticultural specimens) has not been observed to fruit and develop viable seed for over a decade. One stand of this threatened Hunter Valley population of Acacia pendula was monitored over a seven month period (January to July 2018) to investigate this poor reproductive output. Despite copious bud production in January and February, the extent and condition of these, and all subsequent flowers rapidly declined, and none progressed to fruit.
Primary reasons for reproductive failure were postulated to be a combination of mass desiccation of capitula following extended dry conditions, infestation by native flower- and phyllode-galling midges and thrips (Asphondylia sp., Dasineura glomerata, Kladothrips rugosus), fungal galls (Uromycladium sp.), caterpillars (Ochrogaster lunifer), and mistletoe (Amyema quandang). Collectively, these stressors appear to be eliminating seed production from the study
population; survival is maintained only by the copious root-suckering observed around most plants, particularly after the pressure from stock grazing (cattle, sheep) has been removed. The age of trees studied, based on measures of girth and comparison with growth rates reported for other semi-arid Acacia, was inferred to be between 50 and 150 years. The level of Amyema quandang (mistletoe) infestation on Acacia trees was independent of tree size, and there was no evidence to suggest that mistletoe density alone influenced flowering progress.
Consequences of these observations on future management of Acacia pendula in the Hunter Valley are briefly discussed.
In this article, we profile an empirically grounded, cognitive approach to immersion in digital fiction by combining text-driven stylistic analysis with insights from theories of cognition and reader-response research. We offer a new analytical method for immersive features in digital fiction by developing deictic shift theory for the affordances of digital media. We also provide empirically substantiated insights to show how immersion is experienced cognitively by using Andy Campbell and Judi Alston’s (2015) digital fiction piece WALLPAPER as a case study. We add ‘interactional deixis’ and ‘audible deixis’ to Stockwell’s (2002) model to account for the multimodal nature of immersion in digital fiction. We also show how extra-textual features can contribute to immersion and thus propose that they should be accounted for when analysing immersion across media. We conclude that the analytical framework and reader response protocol that we develop here can be adapted for application to texts across media.
Summary statement When echolocating under demanding conditions e.g. noisy, narrow space, or cluttered environments, frugivorous bats adapt their call pattern by increasing the call rate within biosonar groups.
Abstract For orientation, echolocating bats emit biosonar calls and use echoes arising from call reflections. They often pattern their calls into groups which increases the rate of sensory feedback over time. Insectivorous bats emit call groups at a higher rate when orienting in cluttered compared to uncluttered environments. Frugivorous bats increase the rate of call group emission when they echolocate in noisy environments. Here, calls emitted by conspecifics potentially interfere with the bat’s biosonar signals and complicate the echolocation behavior. To minimize the information loss followed by signal interference, bats may profit from a temporally increased sensory acquisition rate, as it is the case for the call groups. In frugivorous bats, it remains unclear if call group emission represents an exclusive adaptation to avoid interference by signals from other bats or if it represents an adaptation that allows to orient under demanding environmental conditions. Here, we compared the emission pattern of the frugivorous bat Carollia perspicillata when the bats were flying in noisy versus silent, narrow versus wide or cluttered versus non-cluttered corridors. According to our results, the bats emitted larger call groups and they increased the call rate within the call groups when navigating in narrow, cluttered, or noisy environments. Thus, call group emission represents an adaptive behavior when the bats orient in complex environments.
Strong convergence rates for numerical approximations of stochastic partial differential equations
(2018)
In this thesis and in the research articles which this thesis consists of, respectively, we focus on strong convergence rates for numerical approximations of stochastic partial differential equations (SPDEs). In Part I of this thesis, i.e., Chapter 2 and Chapter 3, we study higher order numerical schemes for SPDEs with multiplicative trace class noise based on suitable Taylor expansions of the Lipschitz continuous coefficients of the SPDEs under consideration. More precisely, Chapter 2 proves strong convergence rates for a linear implicit Euler-Milstein scheme for SPDEs and is based on an unpublished manuscript written by the author of this thesis. This chapter extends an earlier result1 by slightly lowering the assumptions posed on the diffusion coefficient and a different approximation of the semigroup. In Chapter 3 we introduce an exponential Wagner-Platen type numerical scheme for SPDEs and prove that this numerical approximation method converges in the strong sense with oder up to 3/2−. Moreover, we illustrate how the (mixed) iterated stochastic-deterministic integrals, that are part of our numerical scheme, can be simulated exactly under suitable assumptions.
The second part of this thesis, i.e. Chapter 4 and Chapter 5, is devoted to strong convergence rates for numerical approximations of SPDEs with superlinearly growing nonlinearities driven by additive space-time white noise. More specifically, in Chapter 4, we prove strong convergence with rate in the time variable for a class of nonlinearity-truncated numerical approximation schemes for SPDEs and provide examples that fit into our abstract setting like stochastic Allen-Cahn equations. Finally, in Chapter 5, we extend this result with spatial approximations and establish strong convergence rates for a class of full-discrete nonlinearity truncated numerical approximation schemes for SPDEs. Moreover, we apply our strong convergence result to stochastic Allen-Cahn equations and provide lower and upper bounds which show that our strong convergence result can, in general, not essentially be improved.
"... et quod hodie exemplis tuemur, inter exempla erit." Mit diesen Worten beendete der römische Historiograph Publius Cornelius Tacitus die von ihm konzipierte Version der Gallierrede aus dem Jahr 48 n. Chr., die er dem römischen Princeps Claudius in den Mund gelegt hatte. Tacitus griff hier mit den Exempla der Vorfahren ein wichtiges Argument der konservativen römischen Nobilität auf, durch das diese ihr Handeln häufig legitimierte, und ließ es seinen Claudius dafür nutzen, um die Aufnahme von gallischen Notabeln, also eine auf den ersten Blick noch nie dagewesene Neuerung, zu rechtfertigen. Dazu wählte er beispielhafte Episoden aus der römischen Geschichte, die verdeutlichten, dass die Vorfahren selbst ebenfalls Neuerungen zugelassen hatten, die sich im Nachhinein als sehr wichtig für die römischen Erfolge herausgestellt hatten. Damit widersprächen Neuerungen folglich nicht dem mos maiorum, dem für das römische Moralverständnis grundlegenden Wertekanon, sondern seien vielmehr integraler Bestandteil desselben. ...

Cultural psychology assumes that the ecocultural conditions of a particular setting shape children’s pathways, resulting in multiple adaptive solutions to universal developmental tasks. While the adaptivity of attachment and children’s psychosocial development during the early years has been thoroughly investigated, attachment research during middle childhood continues to reflect Western ideals of family. Adhering to ideas of monotropy, most studies only focus on parental attachment figures. However, this restricted empirical perspective does not only result in a Eurocentric bias, it also neglects theoretical reflections on the growing complexity of attachment during middle childhood, thus only considering a limited selection of all individuals contributing to the children’s feeling of security, even in Western settings. To investigate the variability and adaptivity of attachment during middle childhood, this study assessed children’s attachment figures in two extreme settings of development, introducing an exhaustive network perspective on attachment during this developmental stage. Children of the Cameroonian Nseh (N = 11) and German children from Bad Nauheim (N = 11) identified and differentiated all individuals contributing to their attachment need in an exploratory and transdisciplinary approach. The socio-structural composition of children’s attachment networks follows the context-specific systems of care and concepts of interconnectedness and the ecological features of each setting, resulting in marked differences between both contexts. The functional composition, however, reflects children’s preoccupation with similar developmental challenges across settings. Same-aged peers contribute to the children’s feeling of safety in both settings, thereby deviating from previous reflections on their subordinate relevance during middle childhood. Overall, these results support the adaptiveness of children’s attachment patterns while also demonstrating universal trends across contexts. They highlight the collective nature of attachment during middle childhood that exceeds the impact of individual dyads. Thus, broad and context-sensitive research strategies become a necessary addition to attachment research in order to generate an exhaustive understanding for children’s development across cultural contexts.
Using photo elicitation to introduce a network perspective on attachment during middle childhood
(2018)
In this article, we develop a child-centered network approach to attachment during middle childhood. Following monotropic ideas, current attachment research focuses on parental attachment figures despite the expansion of the children’s social environment during middle childhood, failing to generate a comprehensive and structured overview of all individuals who ensure the children’s feeling of safety. Relying on quantitative methods, these studies are also dominated by an adult perspective, limiting the children’s contributions. While there have been theoretical drafts of attachment networks during childhood, this article constitutes the first practical implementation. Using photo elicitation interviews and participant observations, we developed an innovative assessment strategy that allows children to exhaustively identify and characterize all their attachment figures on sociostructural and functional dimensions, thus positioning the children at the center of their comprehensive attachment networks that collectively contribute to their feeling of security. We combine qualitative and quantitative data to assess the children’s own understanding of their feeling of security and to locate the individual attachment figure on context-specific social dimensions, thus making the research setting, a clan in Cameroon, an inherent part of the methodological development. The data are translated into multidimensional network diagrams to visualize the children’s perception of their attachment environment and the emerging patterns of their selection. We present an exemplary network, supplementing it with observational data to discuss the ecological validity of our approach.
Bindung bildet in der Erforschung langfristiger psychosozialer Entwicklung ein zentrales Konstrukt. In Bezug auf die Phase der mittleren Kindheit liegt dabei jedoch oft eine eingeschränkte Forschungsperspektive vor: dem Konzept der Monotropie folgend, wird trotz des wachsenden sozialen Umfelds allein Eltern eine besondere Aufmerksamkeit in ihrer Rolle als Bindungsfiguren zugeordnet. Zudem fehlen Studien jenseits westlich-europäischer Entwicklungsverläufe. Ziel der vorliegenden Arbeit ist die explorative Erforschung der transkulturellen Spannbreite und der kontextspezifischen Adaptivität in der Auswahl und Funktionalität von Bindungsfiguren der mittleren Kindheit. Dazu werden Daten in zwei ökokulturell gegensätzlichen Settings erhoben, um kontextspezifische und globale Trends betrachten zu können.
Zunächst erfolgt eine ethnologische Annäherung an die frühste Kindheit im kamerunischen Setting der Nseh entlang des Tragetuchs als zentralem Care-Objekt. Diese offenbart eine symbiotische Beziehungsgestaltung, aber auch strenge Regeln des Aufbaus und der Abgrenzung im geteilten Care-System.
Anschließend wird eine methodische Strategie zur Erforschung der mittleren Kindheit entwickelt, die eine Netzwerkperspektive beinhaltet und der kindlichen Wahrnehmung folgt. Dabei werden teilnehmende Beobachtungen mit Photo Elicitation Interviews verbunden, um das vollständige Kollektiv der Bindungsfiguren zu identifizieren und in ihren soziostrukturellen und funktionellen Eigenschaften zu charakterisieren. Indem das Setting zum inhärenten Teil der Datenerhebung wird, werden dabei adaptive Prozesse zugänglich.
In Umsetzungen dieser kontextualisierend explorativen Strategie bei den kamerunischen Nseh und im deutschen Bad Nauheim werden die Bindungsnetzwerke der mittleren Kindheit erfasst und in ihrer Adaptivität diskutiert. Der Kontrastvergleich offenbart, dass die Kinder der Nseh im Vergleich zu den Kindern aus Bad Nauheim in der Altersstruktur vielfältigere, räumlich enger begrenzte und zeitlich stabilere Netzwerke beschreiben. In beiden Settings identifizieren die Kinder eine Aufteilung der inhaltlich-funktionelle Verantwortlichkeiten, die bei den Nseh gemäß den Altersgruppen verläuft.
Insgesamt zeichnet sich für die mittlere Kindheit ein komplexes Bindungsumfeld ab. Dabei verbinden sich settingspezifische Kindheitsbedingungen mit globalen Entwicklungsthemen. Das mehrdimensionale kindliche Sicherheitsgefühl kann auf die Wirkung eines Kollektivs an Bindungsfiguren zurückgeführt werden, zu dem kontextunabhängig in einem bedeutsamen Ausmaß auch Peers gehören.
It is shown that the description of a relativistic fluid at local thermodynamic equilibrium depends on the particular quantum stress-energy tensor operator chosen, e.g., the canonical or symmetrized Belinfante stress-energy tensor. We argue that the Belinfante tensor is not appropriate to describe a relativistic fluid whose macroscopic polarization relaxes slowly to thermodynamic equilibrium and that a spin tensor, like the canonical spin tensor, is required. As a consequence, the description of a polarized relativistic fluid involves an extension of relativistic hydrodynamics including a new antisymmetric rank-two tensor as a dynamical field. We show that the canonical and Belinfante tensors lead to different predictions for measurable quantities such as spectrum and polarization of particles produced in relativistic heavy-ion collisions.
The aim of this study is to trace back the translator of "Reinhold Lubenau Seyahatnamesi [Osmanlı Ülkesinde, 1587-1589]" and focus on her translation approach through paratexts. The traveller portrays the Muslim 'other' whom he met in the Ottoman Empire where he spent his time between the years 1587-1589, when the Ottoman Empire had the power and Islam was being perceived as a threat to them versus his own culture which he belonged to as a Prussian Protestant. The translation of this itinerary is available to Turkish readers after approximately 400 years in 2012. What makes this translation interesting is the translation of a source text, in which the target culture was being portrayed from the perspective of the 'other', into a target language. How was this 'foreign' perspective constructed by the traveler translated and reflected in the paratext? What was the approach of the translator against the challenges he encountered during the translation process? Answers to these questions among many others were being searched through an examination of paratexts. In addition, it was also discussed whether the author moved to the reader or the reader moved to the author. Paratexts encourage reading and direct the reception (Genette 2016). In this study, book covers, names, titles, genre, graphics illustration and footnotes were examined. Translator footnotes, which were provided by the translator in order to make the text clear, were classified in order to underline the functions of these footnotes. Translator footnotes are the tools, which make translators visible and help them to raise their voices in the texts. In peritexts, translator can provide extra information to the readers, explain and justify his/her translation decisions.
This paper traces the military role of Tibnīn and its rulers in the Latin East against the Muslims until 1187/ 583. Tibnīn played a key role in overcoming the Muslims in Tyre and controlled it in 1124. It also played a vital role in the conflict between Damascus and the Kingdom of Jerusalem. Tibnīn participated in defending Antioch, Banyas, Hebron and Transjordan several times. Furthermore, its soldiers and Knights joined the army of the Kingdom of Jerusalem to capture Ascalon in 1153, and joined the campaigns of Amaury I, King of Jerusalem, against Egypt from 1164 to1169. The military situation of Tibnīn under the rule of the royal house until its fall to the Muslims in 1187/ 583 will be studied as well
Rolf Schneider gehörte zu jenen DDR-Schriftstellern, deren Romane um 1970 überwiegend in der Bundesrepublik herauskamen. Auch war er Teil der Gruppe von Autoren, die von 1978 bis 1981 langfristige Visa erhielten und zwischen Ost- und Westdeutschland hin- und herpendelten. Es ist anzunehmen, dass der Umstand, gleichsam zwischen den Stühlen zu sitzen, Schneiders Autorschaft in hohem Maß bedingte. Damit ist zugleich die Frage aufgeworfen, in welcher Weise dies der Fall war. Im Beitrag soll dem anhand der 1965 erschienenen Erzählung Metamorphosen nachgegangen werden. Sie bietet sich hier deshalb als Textgrundlage an, da sie eine intertextuelle Relation zu Die Verwandlung von Franz Kafka aufweist, dessen Werk von den Kulturfunktionären der DDR bis in die 70er Jahre hinein abgelehnt und aus dem offiziellen "Erbe"-Kanon ausgeschlossen wurde. Vor diesem Hintergrund ist davon auszugehen, dass die in Metamorphosen enthaltenen Anspielungen auf den Kafka-Text Schneider zur Inszenierung seiner regimekritischen Autorschaft dienten. Wie dies im Einzelnen aussah, ist Gegenstand der Untersuchung, die sich den intertextuellen Bezügen von verschiedenen Seiten annähern wird, um so die Aspekte zu beleuchten, die für die literarische Selbstdarstellung Schneiders maßgeblich sind.
