Animacy matters: ERP evidence for the multi-dimensionality of topic-worthiness in Chinese
2013
Abstract An event-related potential (ERP) study was conducted to investigate how animacy interacts with givenness during topic processing. Both animacy and givenness have been considered as within-discourse factors that contribute to an element׳s potential to form an optimal topic (i.e., topic-worthiness). ERPs were recorded while participants read question–answer pairs, of which the target sentence induced either a continuation or an alternation of a previously introduced topic (i.e., given vs. new). Depending on the context, a potential topic further differed in its animacy from the preceding one (i.e., animate vs. inanimate). The data revealed a robust givenness effect with an N400 reduc…
Brain lateralization of metrical accenting in musicians.
2009
The perception of meter, or the alternation of strong and weak beats, was assessed in musically trained listeners through magnetoencephalography. Metrical accents were examined with no temporal disruption of the serial grouping of tones. Results showed an effect of metrical processing among identical standard tones in the left hemisphere, with larger responses on strong than on weak beats. Moreover, processing of occasional increases in intensity (phenomenal accents) varied as a function of metrical position in the left hemisphere, but not in the right. Our findings support the view of a relatively early, left-hemispheric effect of metrical processing in musicians.
Large Quadratic Hyperpolarizabilities with Donor–Acceptor Polyenes Exhibiting Optimum Bond Length Alternation: Correlation Between Structure and Hype…
1997
Donor-acceptor polyenes of various lengths, and that combine aro- matic electron-donating moieties with powerful heterocyclic electron-withdraw- ing terminal groups, have been synthe- sized and characterized as efficient non- linear optical (NLO) chromophores. Their linear and nonlinear optical proper- ties have been investigated, and variations in these properties have been related to ground-state polarization (dipole p) and structure. In particular, unprecedented quadratic hyperpolarizabilities (p) have been achieved (up to p(0) =I500 x 10-30esu) by reduction of the bond- length alternation (BLA) in the polyenic chain. In each series of homologous com-
Alternating Chain Magnetism in Catena-μ-Oxo-Hemiporphyrazinatoiron(IV), The First μ-Oxo Linear Chain Complex Of Iron
1984
Abstract X-ray studies, Mossbauer, and magnetism show FeOHp to be an antiferromagneticaly coupled alternating chain with J = -133 cm−1, g = 2.3 and an alternation parameter of 0.4.
The monadic quantifier alternation hierarchy over grids and pictures
1998
The subject of this paper is the expressive power of monadic second-order logic over two-dimensional grids. We give a new, self-contained game-theoretical proof of the nonexpressibility results of Matz and Thomas. As we show, this implies the strictness of the monadic second-order quantifier alternation hierarchy over grids.
Field-free two-direction alignment alternation of linear molecules by elliptic laser pulses
2005
We show that a linear molecule subjected to a short specific elliptically polarized laser field yields postpulse revivals exhibiting alignment alternatively located along the orthogonal axis and the major axis of the ellipse. The effect is experimentally demonstrated by measuring the optical Kerr effect along two different axes. The conditions ensuring an optimal field-free alternation of high alignments along both directions are derived.
Self-employment transitions and alternation in Finnish rural and urban labour markets
2008
. This paper deals with the transitions and alternation between self-employment, paid-employment and non-employment in Finland in 1987–1999, paying special attention to differences in self-employment dynamics between areas characterized by different labour market conditions, viz. rural and urban locations. Markovian analysis reveals significant differences by the type of area in the processes of transition between the three labour market states. Alternation between self-employment and other labour markets states turns out to be greater in rural than urban areas. Five major types of alternating working careers are identified. The type of area is importantly related to alternating working ca…
Resolving the locus of cAsE aLtErNaTiOn effects in visual word recognition: Evidence from masked priming.
2015
Determining the factors that modulate the early access of abstract lexical representations is imperative for the formulation of a comprehensive neural account of visual-word identification. There is a current debate on whether the effects of case alternation (e.g., tRaIn vs. train) have an early or late locus in the word-processing stream. Here we report a lexical decision experiment using a technique that taps the early stages of visual-word recognition (i.e., masked priming). In the design, uppercase targets could be preceded by an identity/unrelated prime that could be in lowercase or alternating case (e.g., table-TABLE vs. crash-TABLE; tAbLe-TABLE vs. cRaSh-TABLE). Results revealed that…
Subject case alternation in Latvian and Estonian existential clauses
2019
In Latvian and Estonian existential clauses, the subject’s case form alternates between nominative vs. genitive (in Latvian) and nominative vs. partitive (in Estonian). This article is a study of the case-alternation systems of existential clauses and related clause types, locative and possessive clauses in these languages. It includes a corpusbased analysis of Latvian existential clauses that is being compared with Estonian corpus-based findings on similar clause types in Estonian. *** Subjekti kaandevaheldus lati ja eesti keele eksistentsiaallausetes Nii eesti kui ka lati keeles esineb subjekti kaandevaheldust. Lati keeles saab subjekt olla lisaks nominatiivile ka genitiivis, eesti keeles…
Anatomy of a grammatical tone
2018
Abstract“Induced Creaky Tone (ICT)” is a grammatical tone in Burmese. It is the result of a process by which Low or High tone is changed into Creaky tone. This alternation is multifunctional, and one of its functions is possessor marking. This paper demonstrates several well-distinguished conditions of different nature and different domain for this tonal alternation. ICT is primarily induced by syntax, varies due to pragmatic factors, occurs only on the shared right boundary of phrases and stem forms, and its phonological condition has a domain stretching to the left boundary of the prosodic word. A comprehensive account of such conditions provides the basis for a grammatical analysis which…
