Noun Incorporation

AbstractThis article proposes a novel account of noun incorporation in Northern Iroquoian. It is proposed that there is no special mechanism for noun incorporation and that this phenomenon falls out naturally from the geometry of the phrase structure under Moro’s theory of Dynamic Antisymmetry. In a nutshell, when the verbal head and the nominal head undergo Merge, they form a point of symmetric c-command, which is resolved by the nominal head moving to the specifier of the verb phrase. Further, it is proposed that, in noun incorporation constructions with a full DP double, the incorporated noun and the DP form a constituent, which is merged in theta-position.

Grammatical Structures

This study focuses on the survey of frequency and occurrence of phrase structure rules used in the written and oral mode of first year tertiary ESL students. It describes the sentence-embedded structures namely, nominal, adjectival and adverbial. As far as phrase structure rules are concerned, the constituents of the noun phrase, verb phrase, adjectival phrase and adverbial phrase are given structural labels. The researcher made use of the quantitative description of the oral and written structures of 76 first year students enrolled in a language class. The results of the study show that majority of the students write their essay using nominals followed by adverbials and the least used are adjectivals. In the oral mode, the most commonly used phrase structure rules are adverbials, followed by nominals and the least used are adjectivals. Though students have a good command of English in writing and speaking, they should be exposed to different communicative situations and develop a balanced style in expressing meaning using varied grammatical structures.

Abstract There have been several research studies that discussed verb phrases. But only some researchers analyse the X-bar theory concerning regional languages in Riau. The author attempts to demonstrate the structure of verb phrase in the Malay dialect of Kampar by using the X-bar theory.This study aims to find and analyse the rules structuring verb phrases contained in the Malay dialect of Kampar. This research was conducted through a field observation by using the descriptive method. According to the findings of the study, it is found that the principles for creating verb phrase structures in Kampar dialect were. 1) FV ---> V+N, ŋikIʸ umpʷIɁ ‘(me)motong rumput’/ Cut the grass; 2) FV ---> V+Spes, bagoɣaɁ lo ‘memasak’/ cook; 3) FV ---> Spes+V, ola makan ‘sudah makan’/ have got the food; 4) FV ---> NEG+V+Spes, ndaɁ dataŋ do ‘tidak datang’/ did not come; 5) FV ---> V+V, paʸ makan ‘pergi makan’/ get to eat;  6) FV ---> Adj+V, paya ŋasʷoňo ‘susah mengasuhnya/menjaganya’/ its hard to take care of; and 7) FV ---> V, motoŋ ‘menoreh/menyadap karet’/ tap the rubber.

Head Element

At the crossroads of linguistic theories: Verb combinatoricsThis paper discusses the limitations of syntactic research conducted within a single theoretical framework. The basic claim is that theories have both distinctive and common features, which can be taken into consideration and some interesting results and ideas can be encoded in terms of the original theory. The discussion of the theory interactions is focused around a particular linguistic issue – the head element of the simple verb phrase. Three basic syntactic models are analyzed in regard to their treatment of the head element in the verb phrase: Phrase Structure Grammar, Head-Driven Phrase Structure Grammar, Systemic Functional Grammar. The analysis shows some variations within the frameworks and similarities across them. In general, it is an attempt to point out that the modern linguist can build bridges between theoretical frameworks if the postulates of the original framework are not violated. Na skrzyżowaniu teorii językowych. Kombinatoryka czasownikowaArtykuł poświęcony jest omówieniu ograniczeń analizy syntaktycznej, dokonywanej w ramach jednej teorii składniowej. Autorka stoi na stanowisku, że poszczególne teorie zawierają zarówno elementy specyficzne (dystynktywne), jak i ogólne, wspólne wszystkim teoriom. Ta inspekcja może przynieść ciekawe rezultaty, które nadają się do wbudowania w oryginalną teorię. Problem przedstawiono na konkretnym przykładzie – elementu nadrzędnego frazy werbalnej. Pod uwagę wzięto trzy teorie syntaktyczne, w ramach których przeanalizowano charakterystykę funkcjonowania głównego elementu frazy werbalnej: Phrase Structure Grammar, Head-Driven Phrase Structure Grammar oraz Systemic Functional Grammar. Analiza wykazała pewną wariantywność wbudowaną w ramy pojedynczej teorii, jak i podobieństwa między poszczególnymi teoriami.Artykuł ma na celu zwrócenie uwagi na fakt, że współczesny lingwista ma prawo próbować przerzucać mosty pomiędzy różnymi teoriami, oczywiście jeśli nie narusza zasadniczych ram oryginalnej teorii.

English Syntax

The purpose of this study is to show that the theory of English syntax contains at least two phrase structure rules (cf. Chomsky, 1956, 1961) which introduce sentences. The first of these exemplifies the principle of NOUN PHRASE COMPLEMENTATION by which a sentence is introduced under the immediate domination of a noun phrase (NP). The second is VERB PHRASE COMPLEMENTATION, involving the introduction of a sentence under the immediate domination of a verb phrase (VP). These rules, couched in a workable phrase structure context, will be postulated at the outset. (For a more complete phrase structure component incorporating the principles of noun phrase and verb phrase complementation, cf. Rosenbaum & Lochak, 1966.) It will then be shown (i) that these rules follow as a consequence of syntactic theory previously formulated and independently justified and (ii) that the incorporation of these rules into the grammar of English leads to a compelling account of a wide range of English complex sentence phenomena.

Convergent Beam

Convergent Beam Electron Diffraction is now almost routinely used in the determination of the point- and space-groups of crystalline samples. In addition to its small-probe capability, CBED is also postulated to be more sensitive than X-ray diffraction in determining crystal symmetries. Multiple diffraction is phase-sensitive, so that the distinction between centro- and non-centro-symmetric space groups should be trivial in CBED: in addition, the stronger scattering of electrons may give a general increase in sensitivity to small atomic displacements. However, the sensitivity of CBED symmetry to the crystal point group has rarely been quantified, and CBED is also subject to symmetry-breaking due to local strains and inhomogeneities. The purpose of this paper is to classify the various types of symmetry-breaking, present calculations of the sensitivity, and illustrate symmetry-breaking by surface strains.CBED symmetry determinations usually proceed by determining the diffraction group along various zone axes, and hence finding the point group. The diffraction group can be found using either the intensity distribution in the discs

Polarity Establishment

Cellular asymmetries are vital for generating cell fate diversity during development and in stem cells. In the newly fertilized Caenorhabditis elegans embryo, centrosomes are responsible for polarity establishment, i.e. anterior–posterior body axis formation. The signal for polarity originates from the centrosomes and is transmitted to the cell cortex, where it disassembles the actomyosin network. This event leads to symmetry breaking and the establishment of distinct domains of evolutionarily conserved PAR proteins. However, the identity of an essential component that localizes to the centrosomes and promotes symmetry breaking was unknown. Recent work has uncovered that the loss of Aurora A kinase (AIR-1 in C. elegans and hereafter referred to as Aurora A) in the one-cell embryo disrupts stereotypical actomyosin-based cortical flows that occur at the time of polarity establishment. This misregulation of actomyosin flow dynamics results in the occurrence of two polarity axes. Notably, the role of Aurora A in ensuring a single polarity axis is independent of its well-established function in centrosome maturation. The mechanism by which Aurora A directs symmetry breaking is likely through direct regulation of Rho-dependent contractility. In this mini-review, we will discuss the unconventional role of Aurora A kinase in polarity establishment in C. elegans embryos and propose a refined model of centrosome-dependent symmetry breaking.
