Rigidity versus relativity in adverbial syntax
Creators: name: Kaufman, Daniel
Publisher: name: ZAS Papers in Linguistics
Year: 2004

description: Two diametrically opposed stances have emerged from recent theoretical debates on adverbial syntax. One approach, represented by Alexiadou (1997) and Cinque (1999), espouses a rigid hierarchy of functional projections hosting individual adverbs. The other, represented broadly by Jackendoff (1972), McConnell-Ginet (1982) and most recently Ernst (2002), takes adverb placement to be determined by the semantics of the adverbs themselves as opposed to the functional architecture of the clause. Under the latter view, adverbs may be divided into several categories based on their meaning with each category being licensed in a certain range within the sentence. Here, I undertake a detailed examination of Tagalog adverbs and compare the predictions of the two best articulated recent theories of adverbs, that of Cinque (1999, 2004) and Ernst (2002). The results offer support for some of the basic predictions of the semantically based approach of Ernst. Particularly important are scopal facts which do not obtain a clear explanation under a functional projection-based theory such as Cinque's.

description: Parallax is the most fundamental technique to measure distances to astronomical objects. Although terrestrial parallax was pioneered over 2000 years ago by Hipparchus (ca. 140 BCE) to measure the distance to the Moon, the baseline of the Earth is so small that terrestrial parallax can generally only be applied to objects in the Solar System. However, there exists a class of extreme gravitational microlensing events in which the effects of terrestrial parallax can be readily detected and so permit the measurement of the distance, mass, and transverse velocity of the lens. Here we report observations of the first such extreme microlensing event OGLE-2007-BLG-224, from which we infer that the lens is a brown dwarf of mass M=0.056 +- 0.004 Msun, with a distance of 525 +- 40 pc and a transverse velocity of 113 +- 21 km/s. The velocity places the lens in the thick disk, making this the lowest-mass thick-disk brown dwarf detected so far. Follow-up observations may allow one to observe the light from the brown dwarf itself, thus serving as an important constraint for evolutionary models of these objects and potentially opening a new window on sub-stellar objects. The low a priori probability of detecting a thick-disk brown dwarf in this event, when combined with additional evidence from other observations, suggests that old substellar objects may be more common than previously assumed.

通过三元平衡定律推导出物体间的引力，来自于内部无数电磁波磁场的复杂叠加的结果，天体之间的引力，实际上是它们之间的混沌磁场形成的一种作用力。三元平衡定律甚至推导出，电磁波是如何在三元平衡定律的影响下，是如何一步一步形成电子，基本粒子，原子，分子，物质等。通过这些论证，可以知道天体相对于绝对静止空间的运动，会产生一如果是天体之间形成的这个系统，则是通过混沌磁场力为连接，天体之间的混沌磁场力，包括引力和相对磁场力。如果将地球和它的卫星之间的关系，看做是一个三元平衡系统的话，那么这个系统之间就必然会存在趋同效应。而三元平衡系统的趋同效应，可以作为了解这个系统前世今生的一个突破口。

description: This paper examines substantive noun phrases in Niuean, a Polynesian language of the Tongic subgroup with VSO word order, isolating morphology, and an ergative case system. We describe the allowable orderings of elements in the Niuean noun phrase, which include certain variations in the placement of numerals and the genitive possessor, then we provide a phrasal movement analysis for these variations, treating first the possessor variation, then the numeral variation. Parallels will be drawn between the derivation of nominal and sentential word order.

description: The Feynman, Metropolis and Teller treatment of compressed atoms is extended to the relativistic regimes. Each atomic configuration is confined by a Wigner-Seitz cell and is characterized by a positive electron Fermi energy. The non-relativistic treatment assumes a point-like nucleus and infinite values of the electron Fermi energy can be attained. In the relativistic treatment there exists a limiting configuration, reached when the Wigner-Seitz cell radius equals the radius of the nucleus, with a maximum value of the electron Fermi energy $(E_e^F)_{max}$, here expressed analytically in the ultra-relativistic approximation. The corrections given by the relativistic Thomas-Fermi-Dirac exchange term are also evaluated and shown to be generally small and negligible in the relativistic high density regime. The dependence of the relativistic electron Fermi energies by compression for selected nuclei are compared and contrasted to the non-relativistic ones and to the ones obtained in the uniform approximation. The relativistic Feynman, Metropolis, Teller approach here presented overcomes some difficulties in the Salpeter approximation generally adopted for compressed matter in physics and astrophysics. The treatment is then extrapolated to compressed nuclear matter cores of stellar dimensions with $A\simeq (m_{\rm Planck}/m_n)^3 \sim 10^{57}$ or $M_{core}\sim M_{\odot}$. A new family of equilibrium configurations exists for selected values of the electron Fermi energy varying in the range $0 < E_e^F \leq (E_e^F)_{max}$. Such configurations fulfill global but not local charge neutrality. They have electric fields on the core surface, increasing for decreasing values of the electron Fermi energy reaching values much larger than the critical value $E_c = m_e^2c^3/(e\hbar)$, for $E_e^F=0$. We compare and contrast our results with the ones of Thomas-Fermi model in strange stars.

Consistency and Complementarity of Ethical Values Across the System and Practice of Radiological Protection

description: In 2018, the International Commission on Radiological Protection (ICRP) released Publication 138, which highlights the ethical values foundational to the system of radiological protection. Additional work, both within and beyond the ICRP, has proposed or recommended ethical values associated with applications of the system in different areas, perhaps most notably in medical, veterinary, and environmental radiological protection. There are also existing ethical frameworks not specifically related to radiological protection that are nonetheless relevant to its practice; for example, the Beauchamp and Childress principles of biomedical ethics are highly relevant when it comes to medical uses of radiation and radioactivity. At first glance, it may seem as if there are unique or isolated sets of ethical values that need to be applied depending on the circumstance. Yet while each area of application will indeed have its own unique aspects and associated value judgements, there are consistent and complementary relationships between these ethical values. This presentation highlights similarities and differences of proposals made for different contexts, with emphasis on medical, veterinary, and environmental radiological protection.

description: We study the conductance through finite Aharonov-Bohm rings of interacting electrons weakly coupled to non-interacting leads at two arbitrary sites. This model can describe an array of quantum dots with a large charging energy compared to the interdot overlap. As a consequence of the spin-charge separation, which occurs in these highly correlated systems, the transmittance is shown to present pronounced dips for particular values of the magnetic flux piercing the ring. We analyze this effect by numerical and analytical means and show that the zero-temperature equilibrium conductance in fact presents these striking features which could be observed experimentally.

description: We investigate the problem of an ultracold atomic gas in the superfluid phase flowing in the presence of a potential barrier or a periodic potential. We use a hydrodynamic scheme in the local density approximation (LDA) to obtain an analytic expression for the critical current as a function of the barrier height or the lattice intensity, which applies to both Bose and Fermi superfluids. In this scheme, the stationary flow becomes energetically unstable when the local superfluid velocity is equal to the local sound velocity at the point where the external potential is maximum. We compare this prediction with the results of the numerical solutions of the Gross-Pitaevskii and Bogoliubov-de Gennes equations. We discuss the role of long wavelength excitations in determining the critical velocity. Our results allow one to identify the different regimes of superfluid flow, namely, the LDA hydrodynamic regime, the regime of quantum effects beyond LDA for weak barriers and the regime of tunneling between weakly coupled superfluids for strong barriers. We finally discuss the relevance of these results in the context of current experiments with ultracold gases.

description: The [O IV] 25.89 micron line has been shown to be an accurate indicator of active galactic nucleus (AGN) intrinsic luminosity in that it correlates well with hard (10-200 keV) X-ray emission. We present measurements of [O IV] for 89 Seyfert galaxies from the unbiased Revised Shapley-Ames (RSA) sample. The [O IV] luminosity distributions of obscured and unobscured Seyferts are indistinguishable, indicating that their intrinsic AGN luminosities are quite similar and that the RSA sample is well suited for tests of the unified model. In addition, we analyze several commonly used proxies for AGN luminosity, including [O III] 5007 A, 6 cm radio, and 2-10 keV X-ray emission. We find that the radio luminosity distributions of obscured and unobscured AGNs show no significant difference, indicating that radio luminosity is a useful isotropic luminosity indicator. However, the observed [O III] and 2-10 keV luminosities are systematically smaller for obscured Seyferts, indicating that they are not emitted isotropically.

Intraposition and Formosan adverbial heads
Creators: name: Holmer, Arthur
Publisher: name: ZAS Papers in Linguistics
Year: 2004

description: [W]hy are not all Malagasy adverbs postverbal with reverse Cinque order? The predicate raising mechanism […] operates around heads, and this leads Rackowski & Travis (2000: 122) to suggest that preverbal adverbs are not heads, but are phrasal, and are located in the Specifier positions themselves. The crucial consequence of this is that the specifier position is blocked, thus effectively preventing further predicate raising. Given that the entire analysis crucially rests on the assumption that certain elements are heads and others are phrases, it would be an advantage if some independent evidence for the X I XP status of the elements could be unearthed. Unfortunately, such evidence is hard to come by in Malagasy. However, other Austronesian languages with similar word order patterns do display rather robust evidence for the head status of certain elements. One such language in the Formosan language Seediq.

On statives and potentives in western Austronesian (mostly Tagalog)
Creators: name: Himmelmann, Nikolaus P.
Publisher: name: ZAS Papers in Linguistics
Year: 2004

description: This contribution is concerned with prefixed forms in western Austronesian languages which have been called a wide variety of names including 'stative', 'accidental', 'involuntary', 'potential', 'coincidence', 'momentary', and so on. Although widely neglected in the literature, these formations are of major import to the grammar of many western Austronesian languages, where for all event expressions there is an obligatory choice between a neutral form and a form marked for 'involuntariness', 'potentiality', 'coincidence', or the like. Furthermore, this distinction has implications for a wide range of theoretical issues, including the nature of unaccusativity and causativity, split-intransitivity, and the grammar of control and complementation. The main goal of this contribution is to bring some basic order to the fairly broad and, on first sight at least, somewhat heterogeneous range of uses and meanings associated with these forms. I will argue that the different uses can be grouped into two semantically and morphosyntactically quite different construction types, which I will call STATIVE (proper) and POTENTIVE, respectively. Section 2 presents the major uses of the 'stative' prefix ma- in Tagalog. In section 3, it is shown that despite superficial similarities the various examples with ma-marked predicates presented in section 2 involve two different constructions and that the prefix ma- belongs to two different morphological paradigms. Section 4, finally, provides a systematization of stative and potentive uses and discusses similarities and differences between the Tagalog system and superficially similar systems in so-called split-S languages.

description: Subjecting a solution of 228Th to ultrasound (20 kHz, 100W), Cardone et al. [Phys. Lett. A 373 (2009) 1956] claim to observe an increase in the transformation or decay rate of 228Th by a factor of 104. The evidence provided seems however far from conclusive and in part contradictory to the claims made. In fact, looking at the presented data we find it cannot be taken as justification to discard the null hypothesis, namely, that the data from exposed and non exposed samples are drawn from the same distribution. We suggest a number of additional tests that should be made in order to improve the quality of the study and test the hypothesis of so-called piezonuclear reactions.

description: Sneutrino-antisneutrino oscillation can be observed at the LHC by studying a charge asymmetry of the leptons in the final states. We demonstrate this in the context of an anomaly-mediated supersymmetry breaking model which can give rise to a large oscillation probability. The preferred region of the parameter space is characterized by the presence of a sneutrino next-to-lightest supersymmetric particle and a stau lightest supersymmetric particle. We show that the signals studied here have certain correlations with the pattern of the sneutrino oscillation.

description: Ida'an-Begak is a Western Malayo-Polynesian language spoken by approximately 6,000 people on the east coast of Sabah, Malaysia, Borneo and belongs to the Sabahan subgroup of the North Borneo subgroup (Blust 1998). Ida'an-Begak has three dialects, Ida'an, spoken in the villages of Segama to the west of Lahad Datu, Ida'an Sungai spoken in the Kinabatangan and Sandakan districts, and Begak spoken in Ulu Tungku, to the east of Lahad Datu (Banker 1984).1 Moody (1993) deals with Ida'an; this paper concentrates on the Begak dialect. In this paper I will present new data gathered in the field and provide an analysis of the allomorphy. The study is based on spontaneous data as well as examples elicited from my language informants.

description: We present the first results from a high sampling rate, multi-month reverberation mapping campaign undertaken primarily at MDM Observatory with supporting observations from telescopes around the world. The primary goal of this campaign was to obtain either new or improved Hbeta reverberation lag measurements for several relatively low luminosity AGNs. We feature results for NGC 4051 here because, until now, this object has been a significant outlier from AGN scaling relationships, e.g., it was previously a ~2-3sigma outlier on the relationship between the broad-line region (BLR) radius and the optical continuum luminosity - the R_BLR-L relationship. Our new measurements of the lag time between variations in the continuum and Hbeta emission line made from spectroscopic monitoring of NGC 4051 lead to a measured BLR radius of R_BLR = 1.87 (+0.54 -0.50) light days and black hole mass of M_BH = 1.73 (+0.55 -0.52) x 10^6 M_sun. This radius is consistent with that expected from the R_BLR-L relationship, based on the present luminosity of NGC 4051 and the most current calibration of the relation by Bentz et al. (2009a). We also present a preliminary look at velocity-resolved Hbeta light curves and time delay measurements, although we are unable to reconstruct an unambiguous velocity-resolved reverberation signal.

Prosodic realization of negation in Saisiyat and English

Publisher: name: ZAS Papers in Linguistics
Year: 2004

description: The current study focuses on the prosodic realization of negators in Saisiyat, an endangered aboriginal language of Taiwan, and compares its prosodic realization of negation with that of English. The results of this study indicate that sentential subjects are the most acoustically prominent items in the Saisiyat negative sentences measured. This contrasts sharply with the English experimental sentences, in which the negator itself was the most acoustically prominent item. These findings suggest that Saisiyat is a pitch-accent language; thus, the presence of negators does not significantly change the prosodic parameters of surrounding words. English, in contrast, is an intonation language, so the presence of negation results in substantial prosodic modification. This suggests that the phenomenon of negation is universally prominent; however, languages with different prosodic systems will adopt different strategies for realizing prominence.

Vowel dispersion in Truku

description: This study investigates the dispersion of vowel space in Truku, an endangered Austronesian language in Taiwan. Adaptive Dispersion (Liljencrants and Lindblom, 1972; Lindblom, 1986, 1990) proposes that the distinctive sounds of a language tend to be positioned in phonetic space in a way that maximizes perceptual contrast. For example, languages with large vowel inventories tend to expand the overall acoustic vowel space. Adaptive Dispersion predicts that the distance between the point vowels will increase with the size of a language's vowel inventory. Thus, the available acoustic vowel space is utilized in a way that maintains maximal auditory contrast.

description: Concepts developed in the gravitational lensing techniques such as shear, convergence, tangential and radial arcs maybe used to see how tenable inhomogeneous models proposed to explain the acceleration of the universe models are. We study the widely discussed LTB cosmological models. It turns out that for the observer sitting at origin of a global LTB solution the shear vanishes as in the FRW models, while the value of convergence is different which may lead to observable cosmological effects. We also consider Swiss-cheese models proposed recently based on LTB with an observer sitting in the FRW part. It turns out that they have different behavior as far as the formation of radial and tangential arcs are concerned.

description: We study the renormalization of a non-magnetic impurity's scattering potential due to the presence of a massless collective spin mode at a ferromagnetic quantum critical point. To this end, we compute the lowest order vertex corrections in two- and three-dimensional systems, for arbitrary scattering angle and frequency of the scattered fermions, as well as band curvature. We show that only for backward scattering in D=2 does the lowest order vertex correction diverge logarithmically in the zero frequency limit. In all other cases, the vertex corrections approach a finite (albeit possibly large) value in the zero frequency limit. We demonstrate that vertex corrections are strongly suppressed with increasing curvature of the fermionic bands. Moreover, we show how the frequency dependence of vertex corrections varies with the scattering angle. We also discuss the form of higher order ladder vertex corrections and show that they can be classified according to the zero-frequency limit of the lowest order vertex correction. We show that even in those cases where the latter is finite, summing up an infinite series of ladder vertex diagrams can lead to a strong enhancement (or divergence) of the impurity's scattering potential. Finally, we suggest that the combined frequency and angular dependence of vertex corrections might be experimentally observable via a combination of frequency dependent and local measurements, such as scanning tunneling spectroscopy on ordered impurity structures, or measurements of the frequency dependent optical conductivity.

Optimal superconductivity is achieved at a doping concentration p beyond which further increases in doping cause a weakening and eventual disappearance of superconductivity. A potential explanation for this demise is that ferromagnetic fluctuations compete with superconductivity in the overdoped regime. In this case a ferromagnetic phase at very low temperatures is predicted to exist beyond the doping concentration at which superconductivity disappears. Here we report on a direct examination of this scenario in overdoped La2-xSrxCuO4 using the technique of muon spin relaxation. We detect the onset of static magnetic moments of electronic origin at low temperature in the heavily overdoped nonsuperconducting region. However, the magnetism does not exist in a commensurate long-range ordered state. Instead it appears as a dilute concentration of static magnetic moments. This finding places severe restrictions on the form of ferromagnetism that may exist in the overdoped regime. Although an extrinsic impurity cannot be absolutely ruled out as the source of the magnetism that does occur, the results presented here lend support to electronic band calculations that predict the occurrence of weak localized ferromagnetism at high doping.

description: A dynamic scheme basing on equation for T-matrix momentum transfer spectral density and integral representation for Jost function is proposed for local Dirac Hamiltonians in arbitrary N- dimension spaces and for Schrodinger one with singular or nonlocal generalized Yukawa-type potentials. A generalization of the off-shell-Jost function method for that Hamiltonians and universal renormalization procedure of Jost function calculation for singular and nonlocal potentials is proposed.

Cluster strong lensing in the Millennium Simulation: The effect of galaxies and structures along the line-of-sight
Creators: name: Puchwein, Ewald

Publisher: name: arXiv

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: We use ray-tracing through the Millennium simulation to study how secondary matter structures along the line-of-sight and the stellar mass in galaxies affect strong cluster lensing, in particular the cross-section for giant arcs. Furthermore, we investigate the distribution of the cluster Einstein radii and the radial distribution of giant arcs. We find that additional structures along the line-of-sight increase the strong-lensing optical depth by ~10-25%, while strong-lensing cross-sections of individual clusters are frequently boosted by as much as ~50%. The enhancement is mainly due to structures that are not correlated with the lens. Cluster galaxies increase the strong-lensing optical depth by up to a factor of 2, while interloping galaxies are not significant. We conclude that these effects need to be taken into account for predictions of the giant arc abundance, but they are not large enough to fully account for the reported discrepancy between predicted and observed abundances. Furthermore, we find that Einstein radii defined via the area enclosed by the critical curve are 10-30% larger than those defined via radial surface mass density profiles. The contributions of radial and tangential arcs to the radial distribution of arcs can be clearly distinguished. The radial distribution of tangential arcs is very broad and extends out to several Einstein radii. Thus, individual arcs are not well suited for constraining Einstein radii.

Antipassive and specificity in Tagalog
Creators: name: Aldridge, Edith
Publisher: name: ZAS Papers in Linguistics
Year: 2003

description: It is common knowledge in the field of Philippine linguistics that an ang-marked direct object in a non-actor focus clause must be definite or generic, while a ng-marked object in an actor focus clause typically receives a nonspecific interpretation. However, in contexts like wh-questions, the oblique object in an antipassive may be interpreted as specific, as noted by Schachter & Otanes (1972), Maclachlan & Nakamura (1997), Rackowski (2002), and others. […] In this paper, I propose to account for the specificity effects […] within the analysis of Tagalog syntax put forth by Aldridge (2004). I analyze Tagalog as an ergative language […]. Cross linguistically, antipassive oblique objects receive a nonspecific interpretation, while absolutives are definite or generic. I show in this paper how the Tagalog facts can be subsumed under a general account of ergativity.

Summary of the Third SFRP/IRPA Workshop on the Application of the Concept of Tolerability
Creators: name: Lecomte, Jean-François
Publisher: name: Zenodo
Year: 2021
Subjects: Tolerability
Reasonableness

description: Following the discussion during the IRPA 14 Congress in 2016 about the need to a greater visibility of the decision processes to a reasonable level of protection, the SFRP organised three workshops. The two first were face-to-face meetings in Paris in February 2017 and in October 2018. Their objective was to investigate the practical implementation of the optimised principle in three sectors: nuclear, medical, existing exposure situations (radon, radium, post-accident), based on case-studies and working groups. The main conclusion was that optimisation remains a challenge in all sectors and is a proactive and deliberative process to achieve a reasonable “compromise” with all informed stakeholders. The third workshop, organised virtually in May 2021, was focused on the notion of tolerability (or non-tolerability) and its link with the notion of reasonableness for three topics: radon exposure, exposure from Naturally Occurring Radioactive Materials (NORM) and the dismantling of nuclear installations. Like the previous workshops, the work was based on case-studies and working groups. There were around 50 participants from 15 countries. According to the so-called tolerable risk model set for practices by ICRP in its Publication 60 (1991), the range of a tolerable risk is between an unacceptable risk and an acceptable risk. In this model, set only for practices, now planned exposure situations, the boundary between a tolerable risk and an unacceptable risk is the compliance with the dose limits and the risk may be acceptable when the protection is optimised. In the ICRP Publication 138 (2018) on the ethical foundations of the system of radiological protection, the term tolerability is defined as: the degree or extent to which something can be endured. The purpose of the 3rd SFRP/IRPA workshop was to investigate whether the model from Publication 60 is still valid and to try to answer some questions such as: what could be the boundary between tolerable and unacceptable in in diverse exposure situations? What is the rationale of the considered criteria? Who should set this criteria? How? When? What should be done if the situation is not tolerable? If actions are implemented to improve the situation, what process or criteria should be used to determine that the situation became acceptable? Etc. The aim of the presentation is to present the main conclusions drawn from the workshop.

An axiomatic formulation of the Montevideo interpretation of quantum mechanics

description: We make a first attempt to axiomatically formulate the Montevideo interpretation of quantum mechanics. In this interpretation environmental decoherence is supplemented with loss of coherence due to the use of realistic clocks to measure time to solve the measurement problem. The resulting formulation is framed entirely in terms of quantum objects without having to invoke the existence of measurable classical quantities like the time in ordinary quantum mechanics. The formulation eliminates any privileged role to the measurement process giving an objective definition of when an event occurs in a system.

Erwerb des Artikels als Genus-Anzeiger im deutschen Erstspracherwerb
Creators: name: Bewer, Franziska
Publisher: name: ZAS Papers in Linguistics
Year: 2003

description: Die vorliegende Arbeit befasst sich mit dem muttersprachlich Erwerb (L1) des Genus im Deutschen. Im Zentrum der Untersuchung steht die Frage, wie ein Kind aus dem ihm angebotenen Sprachinformationen das komplexe System der Genusmarkierung erwirbt. Sie wird anhand von Daten aus einer Langzeitstudie eines monolingual aufwachsenden deutschen Kindes erörtert. Der Rahmen dieser Arbeit erforderte bei ihrem Aufbau gewisse Einschränkungen. So habe ich mich in der Auswertung der Erwerbsdaten auf den bestimmten Artikel als Genusanzeiger konzentriert. Als Artikel zeichnet er sich gegenüber den ebenfalls genusabhängigen Adjektiven dadurch aus, dass er eine meist obligatorische Konstituente einer Nominalphrase (NP) mit einem Substantiv darstellt. Der bestimmte Artikel wiederum ist einerseits der frequenteste unter den Artikelwörtern und weist andererseits das differenzierteste Formeninventar auf, wobei er als einziger Artikel im Nominativ alle drei Genera differenziert. Auch habe ich mich entschlossen, auf eine Gegenüberstellung und Diskussion verschiedener Spracherwerbstheorien zu verzichten und stattdessen ausführlicher auf die Aspekte, die im Erwerbsprozess selbst und somit für die Datenanalyse relevant sind, einzugehen. Dabei sollen unterschiedliche Ansätze berücksichtigt sowie die aktuelle Forschungslage dargestellt werden.

Year: 2003

description: Ziel der Untersuchung ist der Erwerb von aspektuellen Markierungen im Bulgarischen. Da Bulgarisch über ein nominales Artikelsystem und über eine verbale Aspektkategorie verfügt, liefert es eine ausgezeichnete Gelegenheit, die Verwendung von nominalen und verbalen Aspektmarkierungen im frühen Spracherwerb aufzuzeigen. Der Artikel präsentiert die Daten aus einer Langzeitstudie und einer experimentellen Testreihe. Die Ergebnisse belegen, dass die bulgarischen Kinder am Anfang vom Prinzip der Aspektkomposition Gebrauch machen. Aspektuell unmarkierte Verben werden durch definite Objekte ergänzt, um begrenzte Handlungen auszudrücken. Der schnelle Erwerb der Aspektmorphologie verschiebt die Gewichtung im Satz von den nominalen zu den verbalen Aspektmarkern. Im Alter von zweieinhalb Jahren beherrschen die bulgarischen Kinder die sprachspezifische syntaktische Anforderung, dass perfektiv markierte Prädikate quantitativ definite Argumente verlangen.

Does the acquisition of aspect have anything to do with aspectual pairs?
Creators: name: Gagarina, Natalia Vladimirovna
Publisher: name: ZAS Papers in Linguistics
Year: 2003

description: The purpose of this research was to trace the developmental steps in the acquisition of aspectual oppositions in Russian and to examine the validity of the 'aspect before tense' hypothesis for L1-speaking children. Imperfective/perfective verbs and their inflections, as well as aspectual pairs, were analysed in the first five months of verb production (and the respective months in the input) in three children. Additionally, the first four months of verb production were investigated in one boy with less data. Verb forms marked for the past and for the present occur simultaneously in all children. These early forms relate to 'here and now' situations: verbs marked for the past denote 'resultative' events that are perceived by the children as occurring during the speech time or immediately before it, while verbs marked for the present typically denote on-going events. Thus, with early tense oppositions (or tense morphology) children mark aspectual contrasts in the moment of speech: evidence in favour of the 'aspect before tense' hypothesis. A strong preference in using the perfective aspect for the past and the imperfective aspect for the present events has been found in both adults and children. Further, only very few aspectual pairs were documented within the analysed period (from the onset of verb production to the period when children produce rule-driven inflectional forms). The productive use of the finite forms of perfective and imperfective verbs doesn't concord with the ability of the productive use of the contrastive forms of one lemma. Data suggest that children (start to) learn aspectual forms in an item-based manner. The acquisition of aspectual oppositions (aspectual pairs) is lexically dependent and is guided by the contextual 'thesaurus'. Aspectual pairs are learned in a peace-meal way during much longer, than observed for this article, period of time. Generally, aspect is not learned as a rule, also because there are no (uniform) rules of forming of aspectual pairs, but as the 'satellite' of the inherent lexical meaning of verbs of diverse Aktionsarten. The issues addressed here are relevant for other Slavic languages, exhibiting the morphological category of aspect.
