description: The present work reports synthesis, as well as a detailed and careful characterization of structural, magnetic, and dielectric properties of differently tempered undoped and doped CaCu3Ti4O12 (CCTO) ceramics. For this purpose, neutron and x-ray powder diffraction, SQUID measurements, and dielectric spectroscopy have been performed. Mn-, Fe-, and Ni-doped CCTO ceramics were investigated in great detail to document the influence of low-level doping with 3d metals on the antiferromagnetic structure and dielectric properties. In the light of possible magnetoelectric coupling in these doped ceramics, the dielectric measurements were also carried out in external magnetic fields up to 7 T, showing a minor but significant dependence of the dielectric constant on the applied magnetic field. Undoped CCTO is well-known for its colossal dielectric constant in a broad frequency and temperature range. With the present extended characterization of doped as well as undoped CCTO, we want to address the question why doping with only 1% Mn or 0.5% Fe decreases the room-temperature dielectric constant of CCTO by a factor of ~100 with a concomitant reduction of the conductivity, whereas 0.5% Ni doping changes the dielectric properties only slightly. In addition, diffraction experiments and magnetic investigations were undertaken to check for possible correlations of the magnitude of the colossal dielectric constants with structural details or with magnetic properties like the magnetic ordering, the Curie-Weiss temperatures, or the paramagnetic moment. It is revealed, that while the magnetic ordering temperature and the effective moment of all investigated CCTO ceramics are rather similar, there is a dramatic influence of doping and tempering time on the Curie-Weiss constant.

On correlation between the emergence of finite verbs and the development of utterances in Russian and German
Creators: name: Gagarina, Natalia Vladimirovna
name: Bittner, Dagmar
Publisher: name: ZAS Papers in Linguistics
Year: 2003

description: The study examines the hypotheses that the acquisition of the finite verb is an indispensable and linking constituent of the development of SVO utterances. Four apparently separate or at least separable processes are analysed over 6 months in one Russian and one German child: a) the emergence of verbs in the child’s utterances, b) the occurrence of correctly inflected (finite) verb forms, c) the development of multi-component utterances containing a verb, and c) the emergence of (potential) subjects and objects. Russian and German exhibit rich verb morphology, and in both languages finiteness is strongly correlated with inflectional categories like person, number and tense. With both children we find a correlation in the temporal order of these four processes and – what is more relevant for our study – a dependency of a certain development on the utterance level on the emergence of finite verbs. Further, our investigation shows that language-specific development comes in to play already when children start to acquire verb inflection and becomes more contrastive when we observe the onset of the production of the SVO utterances.

description: Der Beitrag referiert Ergebnisse eines mit Erwachsenen durchgeführten Experiments zum Verständnis des bestimmten Artikels. Das Testmaterial entstammt einem für Kinder konzipierten Blickpräferenzexperiment. Die Durchführung des Tests mit Erwachsenen diente als Kontrolle der Verwendbarkeit der Materialien und der Überprüfung folgender Hypothese: Die referentielle Grundfunktion des Artikels besteht im Verweis auf begrenzte Ganze bzw. einen bestimmten (=begrenzten) Umfang einer Entität. Der interessante Aspekt des Experiments war, dass die Entscheidung zwischen [+begrenzt] vs. [-begrenzt] innerhalb einer pluralischen Kondition fallen musste, die Begrenztheitslesart wurde also nicht durch einzahlig auftretende zählbare Objekte erzeugt. Die Ergebnisse zeigen, dass die pluralische Kondition sich auf das Antwortverhalten der Probanden auswirkte. Probanden mit durchschnittlich längerer Reaktionszeit entscheiden sich anders als Probanden mit vergleichsweise kurzer Reaktionszeit. Während von der Gruppe mit spontanerem Entscheidungsverhalten die Hypothese im Hinblick auf den Artikel bestätigt wurde, scheint sich die Gruppe mit höheren Reaktionszeiten für das prototypischere Bild innerhalb der Pluralkondition zu entscheiden.

description: Surface Brightness Fluctuations (SBF) can provide useful information about the unresolved stellar content of early-type galaxies and spiral bulges. The absolute SBF magnitude Mbar in a given passband depends on the properties of the stellar population and can be predicted by population synthesis models. SBF measurements in different bandpasses are sensitive to different evolutionary stages within the galaxy stellar population. Near-IR SBF magnitudes are sensitive to the evolution of stars within the AGB phase, especially the thermally pulsing AGB, while SBF in the blue and UV are sensitive to the hot horizontal branch and post-AGB stages. Thus, multi-band SBF studies can constrain important evolutionary parameters. Empirically, SBF data at the red end of the optical spectrum (i, z, and potentially y) remain excellent distance indicators. I briefly review some recent work on stellar populations using SBF, primarily from an observational point of view.

description: Brenti and Welker have shown that for any simplicial complex X, the face vectors of successive barycentric subdivisions of X have roots which converge to fixed values depending only on the dimension of X. We improve and generalize this result here. We begin with an alternative proof based on geometric intuition. We then prove an interesting symmetry of these roots about the real number -2. This symmetry can be seen via a nice algebraic realization of barycentric subdivision as a simple map on formal power series in two variables. Finally, we use this algebraic machinery with some geometric motivation to generalize the combinatorial statements to arbitrary subdivision methods: any subdivision method will exhibit similar limit behavior and symmetry. Our techniques allow us to compute explicit formulas for the values of the limit roots in the case of barycentric subdivision.

Studies on the development of grammar in German, Russian and Bulgarian
Creators: name: Gagarina, Natalia

Publisher: name: ZAS Papers in Linguistics
Year: 2003

description: The papers of this 33th volume of the ZAS Papers in Linguistics present intermediate results of the ZAS-project on language acquisition. Currently we deal with the question of which functions children assign to the first grammatical forms they use productively. The goal is to identify grammatical features comprising the child's early grammar. This issue is investigated within the analyses of longitudinal data (cf. the papers of Gagarina/Bittner, Gagarina, Kühnast/Popova/Popov, Bewer) as well as within experimental research (see the papers of Bittner, Kühnast/Popova/Popov). The main topic of this volume is the acquisition of definite articles and verbal aspect. Bewer – who has worked as a student assistant in the project for a long time and wrote her MA-thesis on the topic of the project – investigates children's acquisition of gender features in German. Kühnast/Popova/Popov discuss the correlations between the acquisition of definite articles and verbal aspect in Bulgarian. Bittner presents results of an experimental study on definite article perception in adult German. Gagarina traces the emergence of aspectual oppositions in Russian and examines the validity of the 'aspect before tense' hypothesis for L1-speaking children. Additionally, the paper of Gagarina/Bittner deals with the interrelation between the acquisition of finiteness and verb arguments in Russian and German.

Phonetic and phonological aspects of Slavic sibilant fricatives
Creators: name: Zygis, Marzena
Publisher: name: ZAS Papers in Linguistics
Year: 2003

description: In this artiele I reanalyze sibilant inventories of Slavic languages by taking into consideration acoustic. perceptive and phonological evidence. The main goal of this study is to show that perception is an important factor which determines the shape of sibilant inventories. The improvement of perceptual contrast essentially contributes to creating new sibilant inventories by (i) changing the place of articulation of the existing phonemes (ii) merging sibilants that are perceptually very close or (iii) deleting them. It has also been shown that the symbol s traditionally used in Slavic linguistics corresponds to two sounds in the IP A system: it stands for a postalveolar sibilant (ʃ) in some Slavic languages, as e.g. Bulagarian, Czech, Slovak, some Serbian and Croatian dialects, whereas in others like Polish, Russian, Lower Sorbian it functions as a retroflex (ʂ). This discrepancy is motivated by the fact that ʃ is not optimal in terms of maintaining sufficient perceptual contrast to other sibilants such as s and ɕ. If ʃ occurs together with s (and sʲ) there is a considerable perceptual distance between them but if it occurs with ɕ in an inventory, the distance is much smaller. Therefore, the strategy most languages follow is the change from a postalveolar to a retroflex sibilant.

evolution of sibilants in Polish and Russian

Publisher: name: ZAS Papers in Linguistics
Year: 2003

description: In this paper we provide an account of the historical development of Polish and Russian sibilants. The arguments provided here are of theoretical interest because they show that (i) certain allophonic rules are driven by the need to keep contrasts perceptually distinct, (ii) (unconditioned) sound changes result from needs of perceptual distinctiveness, and (iii) perceptual distinctiveness can be extended to a class of consonants, i.e. the sibilants. The analysis is cast within Dispersion Theory by providing phonetic and typological data supporting the perceptual distinctiveness claims we make.

German glide formation functionally viewed
Creators: name: Hamann, Silke
Publisher: name: ZAS Papers in Linguistics
Year: 2003

description: Glide formation, a process whereby an underlying high front vowel is realized as a palatal glide, is shown to occur only in unstressed prevocalic position in German, and to be blocked by specific surface restrictions such as *ji and *ʁj. Traditional descriptions of glide formation (including derivational as well as Optimality theoretic approaches) refer to the syllable in order to capture its conditions. The present study illustrates that glide formation (plus the distribution of long and short tense /i/) in German can better be captured in a Functional Phonology account (Boersma 1998) which makes reference to stress instead of the syllable and thus overcomes problems of former approaches.

description: Gliese 436 is an M dwarf with a mass of 0.45 Msun and hosts the extrasolar planet GL 436b [3, 6, 7, 2], which is currently the least massive transiting planet with a mass of ~23.17 Mearth [10], and the only planet known to transit an M dwarf. GL 436b represents the first transiting detection of the class of extrasolar planets known as "Hot Neptunes" that have masses within a few times that of Neptune's mass (~17 Mearth) and orbital semimajor axis <0.1 AU about the host star. Unlike most other known transiting extrasolar planets, GL 436b has a high eccentricity (e~0.16). This brings to light a new parameter space for habitability zones of extrasolar planets with host star masses much smaller than typical stars of roughly a solar mass. This unique system is an ideal candidate for orbital perturbation and transit-time variation (TTV) studies to detect smaller, possibly Earth-mass planets in the system. In April 2008 we began a long-term intensive campaign to obtain complete high-precision light curves using the Apache Point Observatory's 3.5-meter telescope, NMSU's 1-meter telescope (located at APO), and Sommers Bausch Observatory's 24" telescope. These light curves are being analyzed together, along with amateur and other professional astronomer observations. Results of our analysis are discussed. Continued measurements over the next few years are needed to determine if additional planets reside in the system, and to study the impact of other manifestations on the light curves, such as star spots and active regions.

Towards a typology of stop assibilation
Creators: name: Hall, Tracy Alan
name: Hamann, Silke
Publisher: name: ZAS Papers in Linguistics
Year: 2003

description: In this article we propose that there are two universal properties for phonological stop assibilations, namely (i) assibilations cannot be triggered by /i/ unless they are also triggered by /j/, and (ii) voiced stops cannot undergo assibilations unless voiceless ones do. The article presents typological evidence from assibilations in 45 languages supporting both (i) and (ii). It is argued that assibilations are to be captured in the Optimality Theoretic framework by ranking markedness constraints grounded in perception which penalize sequences like [ti] ahead of a faith constraint which militates against the change from /t/ to some sibilant sound. The occurring language types predicted by (i) and (ii) will be shown to involve permutations of the rankings between several different markedness constraints and the one faith constraint. The article demonstrates that there exist several logically possible assibilation types which are ruled out because they would involve illicit rankings.

Dissipation effects in the ratchetlike Fermi acceleration

description: Ac driven asymmetric pulses can be used to control the Fermi acceleration between three different motions, ${\bf A:}$ the {\it accelerated} mode; ${\bf D:}$ the {\it decelerated} mode and ${\bf H:}$ the {\it hyperaccelerated} mode. In this work we show that dissipation strongly affects the particles velocity, reducing the possibility for an accurate control of the dynamics. The saturation time, where the mean velocity starts to be constant due to dissipation, decays with a power law $\simγ^{-β}$, where $γ$ is the dissipation parameter and $β$ is close to 1. The value of the saturated mean velocity also decays with a power law with exponent $β\sim0.6$ for the case ${\bf H}$, and $β\sim0.3$ for the case ${\bf A}$. In the case ${\bf D}$ this velocity is almost constant for small dissipations.

Anti-structure preservation effects in optimality theory
Creators: name: Hall, Tracy Alan
Publisher: name: ZAS Papers in Linguistics
Year: 2003

description: The present study examines a particular kind of rule blockage – referred to below as an 'antistructure-preservation effect'. An anti-structure-preservation effect occurs if some language has a process which is preempted from going into effect if some sequence of sounds [XY] would occur on the surface, even though other words in the language have [XY] sequences (which are underlyingly /XY/). It will be argued below that anti-structure-preservation effects can be captured in Optimality Theory in terms of a general ranking involving FAITH and MARKEDNESS constraints and that individual languages invoke a specific instantiation of this ranking. A significant point made below is that while anti-structure-preservation effects can be handled straightforwardly in terms of constraint rankings they typically require ad hoc rule-specific conditions in rule-based approaches.

independence of phonology and morphology: the Celtic mutations
Creators: name: Green, Antony D.
Publisher: name: ZAS Papers in Linguistics
Year: 2003

description: One of the most important insights of Optimality Theory (Prince & Smolensky 1993) is that phonological processes can be reduced to the interaction between faithfulness and universal markedness principles. In the most constrained version of the theory, all phonological processes should be thus reducible. This hypothesis is tested by alternations that appear to be phonological but in which universal markedness principles appear to play no role. If we are to pursue the claim that all phonological processes depend on the interaction of faithfulness and markedness, then processes that are not dependent on markedness must lie outside phonology. In this paper I will examine a group of such processes, the initial consonant mutations of the Celtic languages, and argue that they belong entirely to the morphology of the languages, not the phonology.

description: The Springer variety is the set of flags stabilized by a nilpotent operator. In 1976, T.A. Springer observed that this variety's cohomology ring carries a symmetric group action, and he offered a deep geometric construction of this action. Sixteen years later, Garsia and Procesi made Springer's work more transparent and accessible by presenting the cohomology ring as a graded quotient of a polynomial ring. They combinatorially describe an explicit basis for this quotient. The goal of this paper is to generalize their work. Our main result deepens their analysis of Springer varieties and extends it to a family of varieties called Hessenberg varieties, a two-parameter generalization of Springer varieties. Little is known about their cohomology. For the class of regular nilpotent Hessenberg varieties, we conjecture a quotient presentation for the cohomology ring and exhibit an explicit basis. Tantalizing new evidence supports our conjecture for a subclass of regular nilpotent varieties called Peterson varieties.

description: The dense cores of X-ray emitting gaseous halos of large elliptical galaxies with temperatures below about 0.8 keV show two prominent Fe XVII emission features, which provide a sensitive diagnostic tool to measure the effects of resonant scattering. We present here high-resolution spectra of five bright nearby elliptical galaxies, obtained with the Reflection Grating Spectrometers (RGS) on the XMM-Newton satellite. The spectra for the cores of four of the galaxies show the Fe XVII line at 15.01 Angstrom being suppressed by resonant scattering. The data for NGC 4636 in particular allow the effects of resonant scattering to be studied in detail and to prove that the 15.01 Angstrom line is suppressed only in the dense core and not in the surrounding regions. Using deprojected density and temperature profiles for this galaxy obtained with the Chandra satellite, we model the radial intensity profiles of the strongest resonance lines, accounting for the effects of resonant scattering, for different values of the characteristic turbulent velocity. Comparing the model to the data, we find that the isotropic turbulent velocities on spatial scales smaller than about 1 kpc are less than 100 km/s and the turbulent pressure support in the galaxy core is smaller than 5% of the thermal pressure at the 90% confidence level, and less than 20% at 95% confidence. Neglecting the effects of resonant scattering in spectral fitting of the inner 2 kpc core of NGC 4636 will lead to underestimates of the chemical abundances of Fe and O by ~10-20%.

Perturbative reconstruction of a gravitational lens: when mass does not follow light
Creators: name: Alard, C.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: The structure and potential of a complex gravitational lens is reconstructed using the perturbative method presented in Alard 2007, MNRAS, 382L, 58; Alard 2008, MNRAS, 388, 375. This lens is composed of 6 galaxies belonging to a small group. The lens inversion is reduced to the problem of reconstructing non-degenerate quantities: the 2 fields of the perturbative theory of strong gravitational lenses. Since in the perturbative theory the circular source solution is analytical, the general properties of the perturbative solution can be inferred directly from the data. As a consequence, the reconstruction of the perturbative fields is not affected by degeneracy, and finding the best solution is only a matter of numerical refinement. The local shape of the potential and density of the lens are inferred from the perturbative solution, revealing the existence of an independent dark component that does not follow light. The most likely explanation is that the particular shape of the dark halo is due to the merging of cold dark matter halos. This is a new result illustrating the structure of dark halos at the scale of galaxies.

Mechanisms of contrasting Korean velar stops: a catalogue of acoustic and articulatory parameters
Creators: name: Brunner, Jana
name: Fuchs, Susanne

name: Kim, Hyeon-Zoo
Publisher: name: ZAS Papers in Linguistics
Year: 2003

description: The Korean stop system exhibits a three-way distinction in velar stops among /g/, /k'/ and /kh/. If the differentiation is regarded as being based on voicing, such a system is rather unusual because even a two-way distinction between a voiced and a voicless unaspirated velar stop gets easily lost in the languages of the world especially in the case of velar stops. One possibility for maintainig this distinction is that supralaryngeal characteristics like articulators' velocity, duration of surrounding vowels or stop closure duration are involved. The aim of the present study is to set up a catalogue of parameters which are involved in the distinction of Korean velar stops in intervocalic position. Two Korean speakers have been recorded via Electromagnetic Articulography. The word material consisted of VCV-sequences where V is one of the three vowels /a/, /i/ or /u/ and C one of the Korean velars /g/, /k'/ or /kh/. Articulatory and acoustic signals have been analysed It turned out that the distinction is only partly built on laryngeal parameters and that supralaryngeal characteristics differ for the three stops. Another result is that the voicing contrast is not a matter of one parameter, but there is always a set of parameters involved. Furthermore, speakers seem to have a certain freedom in the choice of these parameters.

description: Two-flavor chiral expansions provide a useful perturbative framework to study hadron properties. Such expansions should exhibit marked improvement over the conventional three-flavor chiral expansion. Although one can theoretically formulate two-flavor theories for the various hyperon multiplets, the nearness of kaon thresholds can seriously undermine the effectiveness of the perturbative expansion in practice. We investigate the importance of virtual kaon thresholds on hyperon properties, specifically their masses and isovector axial charges. Using a three-flavor expansion that includes SU(3) breaking effects, we uncover the underlying expansion parameter governing the description of virtual kaon thresholds. For spin-half hyperons, this expansion parameter is quite small. Consequently virtual kaon contributions are well described in the two-flavor theory by terms analytic in the pion mass-squared. For spin three-half hyperons, however, one is closer to the kaon production threshold, and the expansion parameter is not as small. Breakdown of SU(2) chiral perturbation theory is shown to arise from a pole in the expansion parameter associated with the kaon threshold. Estimating higher-order corrections to the expansion parameter is necessary to ascertain whether the two-flavor theory of spin three-half hyperons remains perturbative. We find that, despite higher-order corrections, there is a useful perturbative expansion for the masses and isovector axial charges of both spin-half and spin three-half hyperons.

split margin approach to syllable structure
Creators: name: Baertsch, Karen
name: Davis, Stuart
Publisher: name: ZAS Papers in Linguistics
Year: 2003

description: In this paper we focus on the similarities tying together the second segment of an onset cluster and a singleton coda segment. We offer a proposal based on Baertsch (2002) accounting for this similarity and show how it captures a number of observations which have defied previous explanation. In accounting for the similarity of patterning between the second member of an onset and a coda consonant, we propose to augment Prince & Smolensky's (P&S, 1993/2002) Margin Hierarchy so as to distinguish between structural positions that prefer low sonority and those that prefer high sonority. P&S's Margin Hierarchy, which gives preference to segments of low sonority, applies to singleton onsets; this is our M1 hierarchy. Our proposed M2 hierarchy applies both to the second member of an onset and to a singleton coda. The M2 hierarchy differs from the M1 hierarchy in giving preference to consonants of high sonority. Splitting the Margin Hierarchy into the M1 and M2 hierarchies allows us to explain typological, phonotactic, and acquisitional observations that have defied previous explanation. In Section 2 of this paper, we briefly provide background on the links that tie together the second member of an onset and a singleton coda. In Section 3, we review P&S's Margin Hierarchy, showing that it becomes problematic when extended to coda consonants. We then offer our proposal for a split margin hierarchy. Section 4 extends the split margin approach to complex onsets. We then show how it is able to account for various typological, phonotactic, and acquisitional observations. In Section 5, we will conclude the paper by briefly sketching how the split margin approach enables us to analyze syllable contact phenomena without requiring a specific syllable contact constraint (or additional hierarchy) or reference to an external sonority scale.

description: This paper reports on two XMM-Newton observations of the Seyfert 1 Galaxy H0557-385 obtained in 2006, which show the source at an historical low flux state, more than a factor of 10 lower than a previous XMM-Newton look in 2002. The low flux spectrum presents a strong Fe Kalpha line associated to a Compton reflection continuum. An additional spectral line around 6.6 keV is required to fit Kalpha emission from Fe XXV. The spectral curvature below 6 keV implies obscuration by neutral gas with a column density of 8*10^{23}cm^{-2} partially covering the primary emission, which still contributes for a few percent of the soft X-ray emission. Absorption by ionised material on the line of sight is required to fit the deep trough below 1 keV. The comparison of the two spectral states shows that the flux transition is to be ascribed entirely to intervening line-of-sight clouds with high column density.

description: We study the existence and stability of localized states in the two-dimensional (2D) nonlinear Schrodinger (NLS)/Gross-Pitaevskii equation with a symmetric four-well potential. Using a fourmode approximation, we are able to trace the parametric evolution of the trapped stationary modes, starting from the corresponding linear limits, and thus derive the complete bifurcation diagram for the families of these stationary modes. The predictions based on the four-mode decomposition are found to be in good agreement with the numerical results obtained from the NLS equation. Actually, the stability properties coincide with those suggested by the corresponding discrete model in the large-amplitude limit. The dynamics of the unstable modes is explored by means of direct simulations. Finally, while we present the full analysis for the case of the focusing nonlinearity, the bifurcation diagram for the defocusing case is briefly considered too.

description: An association scheme is called skew-symmetric if it has no symmetric adjacency relations other than the diagonal one. In this paper, we study 4-class skew-symmetric association schemes. In J. Ma [On the nonexistence of skew-symmetric amorphous association schemes, submitted for publication], we discovered that their character tables fall into three types. We now determine their intersection matrices. We then determine the character tables and intersection numbers for 4-class skew-symmetric pseudocyclic association schemes, the only known examples of which are cyclotomic schemes. As a result, we answer a question raised by S. Y. Song [Commutative association schemes whose symmetrizations have two classes, J. Algebraic Combin. 5(1) 47-55, 1996]. We characterize and classify 4-class imprimitive skew-symmetric association schemes. We also prove that no 2-class Johnson scheme can admit a 4-class skew-symmetric fission scheme. Based on three types of character tables above, a short list of feasible parameters is generated.

description: Die vorliegende Arbeit geht unmittelbar vom Konzept der Natürlichen Morphologie aus. Am Datenbereich der dt. Substantivflexion soll die explanative Adäquatheit und Prädiktabilität des Konzepts hinsichtlich des Aufbaus und der Veränderung eines Teilflexionssystems als Ganzes überprüft und auf dieser Basis ein Strukturmodell der dt. Substantivflexion vorgeschlagen werden. Insbesondere bei der Erfassung der Gesamtstruktur des Teilflexionssystems werden dabei Probleme des zugrundegelegten theoretischen Ansatzes deutlich werden. Mit der Diskussion und der Überprüfung theoretischer Annahmen, die diese Probleme lösen können, sowie der detaillierten Analyse des Flexionsverhaltens der dt. Substantive soll ein Beitrag zur weiteren Ausformulierung des in eine allgemeine Präferenztheorie einzuordnenden theoretischen Konzepts der Natürlichen Morphologie wie auch zur germanistischen Forschung geleistet werden.

description: We establish new $p$-estimates for the norm of the generalized Beurling--Ahlfors transform $\mathcal{S}$ acting on form-valued functions. Namely, we prove that $\norm{\mathcal{S}}_{L^p(\R^n;Λ)\to L^p(\R^n;Λ)}\leq n(p^{*}-1)$ where $p^*=\max\{p, p/(p-1)\},$ thus extending the recent Nazarov--Volberg estimates to higher dimensions. The even-dimensional case has important implications for quasiconformal mappings. Some promising prospects for further improvement are discussed at the end.

Focus marking in Kikuyu

Publisher: name: ZAS Papers in Linguistics
Year: 2003

description: Im Kikuyu, einer in Kenia gesprochenen Bantusprache, wird Fokus systematisch durch Wortstellung markiert. In dieser Arbeit werden die verschiedenen Varianten der Markierung von Fokus in Frage-Antwortsequenzen dargestellt. Nach einem Überblick über in der Literatur vorhandene Diskussionen des Phänomens wird auf der Grundlage von mit einem Muttersprachler erhobenen Daten eine syntaktische Analyse von Fokuskonstruktionen mit der Partikel ne vorgeschlagen. Ferner werden neue Daten zur Fokussierung verschiedener Satzteile, z.B. der VP, des ganzen Satzes und des Wahrheitswerts, präsentiert. Ziel der Arbeit ist somit, die deskriptive Datenbasis zu Fokuskonstruktionen im Kikuyu zu erweitern und einen theoretischen Beitrag zu ihrer Analyse im Rahmen der generativen Grammatik zu liefern. Die Arbeit wurde im Sommer 2003 als Magisterarbeit an der Humboldt-Universität zu Berlin, Institut für deutsche Sprache und Linguistik, angenommen. In Kikuyu, a Bantu language spoken in Kenya, focus is marked systematically by means of word order. In this study, the different possibilities for marking focus in question answer sequences are presented. After an overview of the discussions of the phenomenon in the literature, a syntactic account for focus constructions with the particle ne is proposed. This account is based on original data that was gathered with a native speaker. In addition, new data on focusing different parts of the sentence, e.g. the VP, the entire sentence, or the truth-value, are presented. The aim of this study thus is to broaden the descriptive basis for focus constructions in Kikuyu and to provide a theoretical contribution to their analysis in the framework of generative grammar.

Zweifelsfall: zweifeln im Deutschen
Creators: name: Fischer, Markus
Publisher: name: ZAS Papers in Linguistics

description: Two main types of sentences are traditionally distinguished in the context of semantic theories of questions and answers: declarative sentences, corresponding to statements, and interrogative sentences, corresponding to questions. The interrogative forms can be further subdivided into dialectical ones (yes-no-questions) and non-dialectical ones (constituent questions). These distinctions are made for both root and embedded sentences. The predicates that select sentential complements fall into three classes: predicates that license only declaratives, those that allow only for interrogatives, and those that embed both types of sentences. In this connection, verbs of doubt are interesting in that they allow for declaratives as well as dialectical interrogatives, while non-dialectical interrogatives do not seem to be appropriate complements. In what follows, our main concern will be with the German verb of doubt zweifeln and its possible sentential complements. Speaker intuitions as to which constructions are grammatical or acceptable vary, particularily with respect to rare expressions like zweifeln. Therefore, interviews and corpus analysis were applied as a means to acquire reliable linguistic data. These as well as data from historical sources and from some languages other than German (esp. English and Italian) are presented and analysed. In the last section, based on the notion of ‘subjective probability’, an attempt is made at explaining the observations.

description: We study the spatial distribution of X-ray selected AGN in the framework of hierarchical co-evolution of supermassive black holes and their host galaxies and dark matter haloes. To this end, we have applied the model developed by Croton et al.(2006), De Lucia & Blaizot(2007) and Marulli et al.(2008) to the output of the Millennium Run and obtained hundreds of realizations of past light-cones from which we have extracted realistic mock AGN catalogues that mimic the Chandra deep fields. We find that the model AGN number counts are in fair agreement with observations, except at fluxes <1e-15 erg/cm^2/s. The spatial two-point correlation function predicted by the model is well described by a power-law relation out to 20 Mpc/h, in close agreement with observations. Our model matches the correlation length r_0 of AGN in the Chandra Deep Field North but underestimates it in the Chandra Deep Field South. When fixing the slope to gamma = 1.4, as in Gilli et al. (2005), the statistical significance of the mismatch is 2-2.5 sigma, suggesting that the predicted cosmic variance, which dominates the error budget, may not account for the different correlation length of the AGN in the two fields. While our results are robust to changes in the model prescriptions for the AGN lightcurves, the luminosity dependence of the clustering is sensitive to the different lightcurve models adopted. However, irrespective of the model considered, the luminosity dependence of the AGN clustering in our mock fields seems to be weaker than in the real Chandra fields. The significance of this mismatch needs to be confirmed using larger datasets.

description: Der vorliegende Band präsentiert zwei Arbeiten, die sich im Themenkreis Frage - Fokus bewegen. Während die Konruenz von Fragen und Fokussierung in einem Kernbereich von Daten gut etabliert ist, bleibt weitgehend unverstanden, welcher Teil der (jeweils sprachspezifischen) Daten im Umfeld von Frageform und Fokussierungskonstruktionen eine kontingente "Korona" dieses Kernbereichs darstellt bzw. wie weit der systematische Zusammenhang zwischen Fragen und Fokussierung reicht. Beide Arbeiten tragen zu einem besseren Verständnis dieses Aspekts bei.
