Abstract:
The article reflects the main results of comparative-typological study concerning the organization of terminological phrases on the basis of four closely related languages - French, Spanish, Italian and Romanian. Attention is focused on the study of theme-rheme organization of phrases on the material of multilingual and bilingual dictionaries in some of the most priority areas of electronics and electrical engineering. Despite the isomorphism of the studied languages, the complex use of a number of methods (comparative-typological method, quantitative analysis, actual division method, questioning of specialist informants) allowed to detect several allomorphic features in the theme-rheme organization of their word combinations. They consist in the use of possessive and definite articles, prepositions, and ordinal numbers. The presence of possessive articles in the Romanian language is recognized as the most striking allomorphic property, thanks to which theme-rheme organization of a Romanian word-combination becomes more transparent in comparison with other Romance languages. The importance of the study of allomorphic features of languages for lexicography, theory and practice of translation is emphasized.

Abstract:
Objective - The objective of this paper is to explore and understand the motivators of institutionalization of Performance Measurement Systems (PMS) in the Indonesian Local Government (ILG), particularly in the Batu municipality presenting the performance paradoxes. Performance accountability issues have been encouraging the Batu municipality to implement PMS since the beginning of the 2000s. Methodology/Technique - The theoretical framework and interpretation of this study are adopted from the institutional theory (coercive, mimetic, normative, and allomorphism) which is used to analyze the phenomenon. The researchers employ a single case study to scrutinize the motivators of institutionalization by elaborating on document analysis conducted from the interviews of 10 employees in a different range of management levels (top, middle, and lower). Findings - The results of this study reveal that exogenous (coercive, mimetic and normative) and endogenous (allomorphism) drivers encourage the institutionalization of PMS in the Batu municipality with coercive pressure as a major driver and allomorphism as a mere ceremonial driver (rather than an instrument). Novelty - The practical implications of this study can be used to improve the PMS process and the quality of performance reporting in the Batu municipality and in other local governments. This paper is also expected to fill the gap in existing literature on the implementation of PMS within a developing country (in this case, Indonesia). Type of Paper: Empirical Paper.

Abstract:
The paper deals with the problem of lacunarity, that is, the allomorphism of languages of different structures on heterogeneous material: translations of different times, lexicographic sources and opinion poll data of native speakers of the same language who study Russian, ways of eliminating lacunae at various historical stages in the development of the lexical system of different languages and the mismatch of signs of nomination, and also describes vector lacunarity in the speech etiquette of the Russian language from the point of view of translation into Arabic. The main approaches to the study of the phenomenon of lacunarity in modern linguistics are considered. A typology of lacunarity is proposed based on the material of languages with different structures.

Abstract:
Many cases of allomorphic alternation are restricted to specific lexical items but at the same time show a regular phonological distribution. Standard approaches cannot deal with these cases because they must either resort to diacritic features or list regular phonological contexts as idiosyncratic. These problems can be overcome if we assume that allomorphs are lexically organized as a partially ordered set. If no ordering is established, allomorphic choice is determined by the phonology—in particular, by the emergence of the unmarked (TETU). In other cases, TETU effects are insufficient, and lexical ordering determines the preference for dominant allomorphs.

Abstract:
Cette thèse en Sciences du Langage se situe dans le cadre de la morphologie verbale historique et étudie le devenir des alternances de bases au présent de l’indicatif en français. Le cadre global est celui d’une étude linguistique associant description du système verbal du français et histoire des représentations du français, et ce dans une diachronie longue, dans la mesure où certains changements sont très anciens et d’autres sont le fait de la période médiévale, tandis que d’autres datent de l’époque moderne.Nous avons décrit le fonctionnement des paradigmes verbaux en synchronie et en diachronie, tout en définissant les concepts fondamentaux utilisés. Nous sommes ainsi revenue sur la notion de « verbe régulier » et de « verbe irrégulier » d’un point de vue historique. Nous avons distingué l’alternance de bases verbale et la variation phonologique de la base. Nous nous sommes arrêtée sur l’analogie, mécanisme d’alignement fondamental dans l’évolution du système verbal, qui peut jouer à l’intérieur du paradigme ou d’un ensemble de paradigmes du même verbe avec notamment l’extension d’une des bases au détriment de l’autre, comme celle la base aim- à tous les tiroirs et en P4 / P5 de l’indicatif présent du verbe aimer, AF amer. Par ailleurs, aux 16e et 17e siècles, où subsistaient encore de nombreuses hésitations, les grammairiens et remarqueurs ont joué un rôle de descripteur et prescripteur de la langue que nous avons essayé de cerner.Pour mener à bien cette étude, nous avons constitué un corpus de 27 verbes représentant plusieurs types d’alternances verbales, comme treuve/trouvons et aime/amons qui a donné 312 250 occurrences brutes en contexte dans Frantext de l’ancien français à 1799. Les verbes ont été regroupés selon leur alternance de départ pour une étude systématique des fréquences et autres paramètres, afin de comprendre pourquoi des verbes qui présentaient des alternances identiques en ancien français n’ont pas connu le même aboutissement en français moderne, et tenter de déterminer les facteurs favorisant le maintien de l’alternance de bases ou, au contraire, les facteurs qui favorisent l’extension d’une des deux bases verbales au présent de l’indicatif.Finalement, de multiples paramètres ont pu jouer dans les transformations et les normalisations des paradigmes verbaux au présent de l’indicatif : la fréquence d’emploi d’une forme, d’une base ou d’un paradigme, l’appartenance d’un verbe à une famille morphologique, l’analogie intra et interparadigmatique et la prescription linguistique aux 16e et 17e siècles. Nous proposons une hiérarchie des critères
This thesis in Linguistics is part of a study of historical verbal morphology and examines the evolution of alternation of verbal stems in the French present tense. The overall framework is that of a linguistic study combining a description of the French verbal system and the history of representations of French language, in a long diachrony context, as certain changes are very old, and others are the result of the medieval period, while some others date from the modern period.We described the functioning of verbal paradigms in synchrony and diachrony, while defining the fundamental concepts used. We thus redefinied the notion of ‘regular verb’ and ‘irregular verb’ from a historical point of view. The alternation of verbal stems and the phonological variation of the verbal stem have been distinguished. We analysed the concept of analogy, a fundamental alignment mechanism in the evolution of the verbal system, that can play a role within a paradigm or a set of paradigms of the same verb, in particular with the extension of one of the verbal stems to the detriment of the other, such as the aim stem - in all the tenses and in P4/P5 of the present tense of the verb aimer (to love), Old French amer. Moreover, in the 16th and 17th centuries, when there was still a lot of hesitation, grammarians and Remarqueurs played a role as descriptors and prescriptors of the language, rôle that we have tried to define.To carry out this study, we compiled a corpus of 27 verbs representing several types of verbal alternation, such as treuve/trouvons (to find) and aime/amons (to love), which yielded 312,250 raw occurrences in context in the Frantext corpus, from Old French to 1799. The verbs were grouped according to their initial alternation for a systematic study of frequencies and other parameters, in order to understand why verbs with identical alternations in Old French did not have the same outcome in modern French. We also tried to determine the factors favouring the maintenance of the verbal alternation or, on the contrary, the factors favouring the extension of one of the two verbal stems in the present tense.Finally, we observed several parameters may have played a part in the transformations and standardisation of verbal paradigms in the present tense: the frequency of use of a form, verbal stem or paradigm, whether a verb belongs to a morphological family, the intra and interparadigmatic analogy, and linguistic prescription in the 16th and 17th centuries. A hierarchy of criteria has been proposed

Abstract:
Allomorphic variation is a common linguistic phenomenon in Jersey (Jersey Norman French). Definite articles in Jersey each have at least two allomorphs. The occurrence of each allomorph has been attributed to the composition of word initial syllable following the article (Liddicoat 1994). Instead of using a ruled-based approach, this thesis examines the variation found among Jersey definite articles and uses sonority-based principles to analyze the allomorphic variation. Using Jersey phonotactics, this thesis first puts forth a Jersey specific sonority hierarchy and then utilizes that hierarchy and principles of syllabification to syllabify phrases containing definite articles. Then using sonority based principles, such as the Sonority Sequencing Principle and Syllable Contact Law, this thesis analyzes the syllabified phrases. The analysis identifies the sonority based conditions that trigger the allomorphic variation found in the data. This thesis contributes to the field of linguistics in several ways. It supports the use of both the Universal Sonority Hierarchy and language specific sonority hierarchies. This thesis also supports the practice of using available data sources for analysis. The analysis of a described but analyzed phenomenon contributes valuable information to the general knowledge of Jersey and sonority. Finally, this thesis also serves as an important resource for the study of Norman dialects in Europe such as Guernsey, Sark and Norman, as Jersey is a member of this linguistic group. This thesis contributes to both the field of Jersey linguistics and to the field of theoretical linguistics, while accounting for the allomorphic variation of Jersey definite articles.

Abstract:
Les trois langues romanes sollicitées ici ne nous donnent plus l'occasion d'observer d'interaction riche entre dérivation, inflexion et phonologie que dans leurs systèmes verbaux.

Une conséquence de cet état de chose est que le marquage individuel des verbes et leur ségrégation selon des paradigmes différents pour chaque marque, sont universellement acceptés. L'idée qu'une morphologie sophistiquée reposant sur l'activation de mécanismes phonologiques serait à même de décrire la flexion des verbes de ces trois langues, est généralement considérée comme peu plausible.

L'ambition de cette thèse est justement de construire une telle morphologie qui capte les intuitions des locuteurs sur la conjugaison. Cette entreprise est sous-tendue par un double à priori :

- négliger totalement le rôle d'informations d'origine diachronique ;
- réduire totalement le rôle de catégories non-reconnues par la théorie linguistique dans la caractérisation de cette connaissance, notamment la notion dite de groupe de verbe.

Ce travail atteint trois objectifs :

1) Supprimer la notion de groupe dans la conjugaison, c'est dériver les formes de surface des verbes des différents groupes à partir d'une morphologie nourrissant des mécanismes phonologiques généraux.
2) Donner un statut à la supplétion et à la défection qui permette de comprendre comment un verbe supplétif ou défectif est représenté dans les grammaires intégrées des locuteurs. Autrement dit, nous voulons non seulement donner un lieu de lexicalisation aux supplétions et aux lacunes mais aussi étudier leur fonctionnement par rapport au paradigme de conjugaison unique que nous postulons.
3) Unifier le traitement des verbes réguliers et irréguliers en utilisant ce même paradigme unique pour tous les verbes. L'intuition couverte par cet objectif, est qu'à partir d'un échantillon de l'irrégularité d'un verbe, un locuteur est capable de faire un certain nombre de généralisation sur les autres irrégularités.

Abstract:
Cet ouvrage tente d'elaborer et d'appliquer au lexique construit (par affixation et conversion) du francais un ensemble coherent et hierarchise de regles et de principes constituant une grammaire generative du lexique. L'hypothese fondamentale sur laquelle repose ce travail est la suivante : les irregularites de tous ordres observables sur la partie attestee du lexique construit cachent des regularites profondes gouvernees par cette grammaire. Sont d'abord envisages les obstacles qui empechent le morphologue de depasser le niveau de l'"evidence": difficultes d'acces aux materiaux, pesanteur des conceptions et des outils traditionnels de l'analyse des mots construits. Les irregularites observables sont soumises a un tri qui permet d'isoler les fausses irregularites, d'origine essentiellement extralinguistique, les sous-regularites, d'ordre formel et semantique, et les veritables idiosyncrasies. Cette redistribution des exceptions apparentes permet de distinguer divers types de mots complexes, de definir de facon contrainte la notion d'operation derivationnelle, enfin de justifier la construction de divers types de regles lexicales hierarchisees entre elles. Est ensuite explicite le fonctionnement detaille d'un modele lexical reposant sur cette analyse stratifiee des donnees. Ce modele est organise en trois composants qui formalisent respectivement les materiaux non construits qui servent aux regles (composant de base), les regles de construction des mots (composant derivationnel), et un ensemble ordonne de filtres charges de conformer le lexique de droit au lexique de fait (composant conventionnel). Il presente vis-a-vis des modeles lexicalistes concurrents l'originalite d'etre a la fois associatif (les regles attribuent aux mots construits une structure morphologique et une interpretation semantique associees), surgeneratif par rapport au lexique atteste, et stratifie, puisque l'organisation du modele respecte la hierarchie des regularites et des diverses irregularites. L'ouvrage est complete par seize annexes developpant des points particuliers ou fournissant des inventaires, et quatre index
This work tries to construct a consistent set of rules and principles organized into a hierarchy and constituting a generative grammar of the lexicon, to be applied to the french lexicon built by affixation and conversion. The main hypothesis is : behind the various irregularities one may observe in the attested part of the "built lexicon", lie deep regularities governed by a grammar such as the one here constructed. First, i analyze the reasons why the morphologists cannot generally see further than the obvious level : difficulties in the access to the material, burdensomeness of the traditional conceptions and tools used for the analysis of the derived words. Second, i sift out the observable irregularities in order to select (i) the apparent irregularities, most of them being extralinguistical, (ii) the formal and semantic subregularities, and (iii) the pure idiosyncrasies. This new classification of the apparent exceptions enables to mark off various types of complex words, then to define restrictively the concept of "derivational operation", finally to justify the hierarchy of various types of lexical rules presented here. Third, the detailed functioning of a lexical model based on such a stratified analysis of the data is explicitly described. This model is organized in three components that formalize (i) the underived material to be used by the rules ("base component"), (ii) the word formation rules ("derivational component"), and (iii) an ordered set of filters which function it is to adjust the de jure lexicon to the de facto one ("conventional component"). In comparison with the other leicalist models, this one is original, being altogether associative (the rules give to the derived words a morphological structure and a semantical interpretation that are associated), overgenerative when compared to the attested lexicon, and stratified, since the model organization agrees with the hierarchy of the regularities and of the various irregularities. The work is completed by sixteen annexes detailing spcific topics or giving corpus, plus four indexes

L'heterogeneite en morphologie flexionnelle est traitee sur un plan general puis sur l'exemple de la flexion substantivale allemande (distribution des allomorphes de pluriel). Apres l'etude des desequilibres intenes du paradigme, examine differentes representations de l'heterogeneite au sein d'une meme categorie morpho-syntaxique (classes flexionnelles, relations logiques, prototypes) et les couplages entre proprietes flexionnelles et non-flexionnelles, les secondes participant a la motivation des classes flexionnelles. L'heterogeneite apparait ainsi comme un reflet de la diversite lexicale. Les faits synchroniques sont replaces dans une conception centree autour du locuteur, apte a manier les formes normales mais aussi a produire des formes nouvelles non-normales susceptibles d'etre reprises par la communaute. La multiplicite des facteurs de motivation 'couplages, processus d'uniformisation) constitue le fondement de l'heterogeneite flexionnelle. La motivation de l'allomorphie peut etre l'objet d'hypotheses plausibles elaborees a partir d'une analyse synchronique et diachronique (avec une attention toute particuliere aux "exceptions". Une telle analyse est ensuite menee sur la flexion substantivale allemande, avec l'etude des relations entre flexion casuelle et symbolisation du pluriel et l'avaluation des differents allomorphes sur la base des differents facteurs qui les motivent
After a general approach of the problem of heterogeneity in inflexional morphology, a second part deals with the domain of german noun inflexion (distribution of plural allomorphs). After investigating the assymetries within a paradigm, different representations of the heterogeneity in a same domain are analysed (inflexional classes, logical relations, prototypes), with special consideration to the linking between inflexional and non-inflexional properties, the latter contribue to the motivation of the inflexional classes ; inflexional heterogeneity reflects lexical diversity. The synchronoc facts are replaced into a speaker-centered conception : the speaker can use normal forms, but also produce new, non-normal ones, which may be adopted by the communauty. The plurality of motivation factors (linkings, uniformisation processes) is analysed as the base inflexional heterogeneity. To explain the motivation of allomorphy, plausibel hypotheses are developed on the base of a synchronic and dischronic analysis (with special consideration to "exceptions"). - the german noun inflexion is then analysed in line with these principles. The specific purposes of the investigation are the relation between case inflexion and number symbolisation and the evaluation of the motivation of the plural allomorphs

Full text
Abstract:

The primary cell wall is a complex multipolymer system whose composite structure has been mostly determined from chemical and biochemical studies. Although the primary cell wall serves a central role, with regard to the connective properties of fibres, knowledge about the interactions among the polymers, when it comes to the mechanical properties, is very limited. The physical properties of the polymers, i.e. their elastic and viscous deformations, as well as the ultrastructure of the polymers, i.e. the interactions among the polymers in the outer fibre wall layers that lead to this behaviour, are still not fully understood.

The aim of this study was to examine how the different wood polymers, viz. lignin, protein, pectin, xyloglucan and cellulose, interact in the outer fibre wall layers of the spruce wood tracheid. The initial objective was to separate an enriched primary cell wall material from a first stage TMP, by means of screening and centri-cleaning. From this material, consisting of the primary cell wall (P) and outer secondary cell wall (S1) materials, thin sheets were prepared and analysed using a number of different analytical methods. The major measuring technique used was dynamic Fourier transform infra-red (FT-IR) spectroscopy in combination with dynamic 2D FT-IR spectroscopy. This technique is based on the detection of small changes in molecular absorption that occur when a sinusoidally stretched sample undergoes low strain. The molecular groups affected by the stretching respond in a specific way, depending on their environment, while the unaffected molecular groups provide no response to the dynamic spectra, by producing no elastic or viscous signals. Moreover, the dynamic 2D FT-IR spectroscopy provides useful information about various intermolecular and intramolecular interactions, which influence the reorientability of functional groups in a polymer material.

Measurements of the primary cell wall material, using dynamic FT-IR spectroscopy, indicated that strong interactions exist among lignin, protein and pectin, as well as among cellulose, xyloglucan and pectin in this particular layer. This was in contrast to the secondary cell wall, where interactions of cellulose with glucomannan and of xylan with lignin were dominant. It was also indicated that the most abundant crystalline cellulose in the primary cell wall of spruce wood fibres is the cellulose Iβ allomorph, which was also in contrast to the secondary cell wall, where the cellulose Iα allomorph is more dominant. The presence of strong interactions among the polymers in the primary cell wall and, especially, the relatively high content of pectin and protein, showed that there is a very good possibility of selectively attacking these polymers in the primary cell wall. The first selective reaction chosen was a low degree of sulphonation, applied by an impregnation pretreatment of chips with a very low charge of sodium sulfite (Na2SO3). This selective reaction caused some structural modification of the lignin, a weakening of the interactions between lignin;pectin, lignin;protein and pectin;protein, as well as an increased softening of the sulphonated primary cell wall material, when compared to the unsulphonated primary cell wall material. All this resulted in an increased swelling ability of the material.

Full text
Abstract:
La présente thèse constitue une étude typologique contrastive des allomorphies pronominales dans deux langues finno-ougriennes : en hongrois et en mordve erzya. On entend ici par typologie contrastive une approche typologique fondée sur la mise en contraste des structures de deux ou plusieurs langues, y compris des langues de la même famille linguistique, afin d’explorer des propriétés à la fois spécifiques et universelles. De ce point de vue, le hongrois et le mordve s’avèrent particulièrement pertinents en termes de structuration des systèmes de marques pronominales, en raison de propriétés morphologiques caractéristiques de l’ouralien central et oriental, tels que l’existence d’une double conjugaison (subjective et objective, voire « objective définie », en mordve), qui induit des séries allomorphiques complexes, tout en suivant des principes réducteurs universels (syncrétisme, sous-spécification et surspécification de certaines marques ou conditions de marquage morphonologique). Cette thèse comprend neuf chapitres, distribués sur trois volets. Le premier volet décrit les structures et les étapes de la modélisation des systèmes pronominaux dans les deux langues. Dans le premier chapitre, nous présentons des généralités historiques et structurales du hongrois et du mordve erzya, ainsi que la place que ces langues occupent parmi les langues finno-ougriennes, du point de vue de la classification et de la typologie. Une série de particularités importantes pour la compréhension des deux systèmes, en termes d’organisation structurale, concerne les propriétés allomorphiques des unités fonctionnelles et relationnelles de type pronominal, telles que l’harmonie vocalique, les suffixes casuels, le système verbal, et l’ordre des mots. Le deuxième chapitre concerne le lien entre les pronoms personnels et des catégories grammaticales fondamentales telles qu’animacité, nombre, personne, définitude, et aboutit à la conclusion que c’est le pronom personnel qui est particulièrement marqué par ces catégories grammaticales – les mêmes qui peuvent avoir, dans les langues du monde, une incidence sur la construction ou l’organisation des systèmes de classes flexionnelles. Le troisième chapitre présente une approche historiographique du hongrois et du mordve erzya; le quatrième chapitre propose une réanalyse de la flexion pronominale erzya, en suivant les mêmes principes que ceux jadis préconisés par András Kornai dans son analyse du système de la flexion nominale du hongrois (Kornai 1994), dans la mesure où ce modèle morphologique traite l’affixation comme une opération sur des traits combinés. Le deuxième volet de cette recherche développe des études de cas exploratoires dans une perspective de TAL : un corpus d’erzya littéraire et un corpus d’erzya biblique sont analysés contrastivement en suivant les démarches et le paramétrage requis par le logiciel Trameur. Le troisième volet sort de l’analyse des registres stylistiques au sein d’une langue donnée pour revenir à une typologie contrastive structurale hongrois-mordve. Dans le dernier chapitre, nous proposons une synthèse de ces deux aspects de la typologie contrastive : contrastes de registres intralangue, contraste de structures interlangues, en fonction d’un ensemble de paramètres partagés. La synergie entre la méthode lexicométrique et la typologie générale constitue l’un des principaux apports heuristiques de cette thèse, dont le but est de développer une typologie des langues finno-ougriennes qui tienne davantage compte de la contrastivité des structures et de leur relativisme que des grands traits catégoriels interlangues, davantage sujets aux biais empiriques et méthodologiques que peuvent recéler les grands corpus
This dissertation provides a contrastive and typological study of pronoun allomorphy in two Finno-Ugric languages: Hungarian and Erzya Mordvin. Contrastive typology is a typological approach aiming at contrasting the structures of two or more languages, including from the same language family, to explore specific and universal properties. From this standpoint, Hungarian and Mordvin are particularly relevant as to the structure of pronoun markers, due to some morphological characteristics of the central and eastern languages of the Uralic language family, such as double conjugation paradigms (subjective and objective, moreover the "objective definite inflectional paradigm" in Mordvin). This results in complex allomorphic patterns, while following universal principles (syncretism, sub-specification and over-specification of certain markers, or the conditions of morphonologic exponence). The first part describes the structures and modelling stages of the pronominal system in both languages. In the first chapter, we present historical and structural generalities about the Hungarian and Mordvin Erzya languages, and the place they occupy within the Finno-Ugric group, from the point of view of classification and typology. A series of important features to understand the two systems in terms of structural organization, concerns the allomorphic properties of functional and relational units of pronominal type such as vowel harmony, the casual suffixes, the verbal system, and word order. The second chapter deals with the relationship between personal pronouns and basic grammatical categories such as animacity, number, person, definiteness, and concludes that it is the personal pronoun that is most marked by these grammatical categories - the same that may affect, in the languages of the world, the construction or organisation of inflectional classes. The third chapter is a historiographical approach of Hungarian and Erzya to show the outline of the research on the evolutionary periods of both systems. The fourth chapter provides a reanalysis of pronominal inflection in Erzya, following the same principles as those previously recommended by András Kornai's analysis of the nominal inflection system of Hungarian (Kornai, 1994), as it deals with the morphological model considering affixation as an operation on the combined features. The second part of this research develops exploratory case studies from the perspective of NLP (French: TAL) a literary corpus and a biblical corpus of Erzya are analysed following the steps and the settings required by the Trameur software. The third part departs from the contrastive analysis of stylistic registers within a given language to return to a Hungarian-Mordvin contrastive structural typology. In the last chapter, we propose a synthesis of these two aspects of contrastive typology: contrasting registers of intralanguage, contrast-linguistic structures, based on a set of shared parameters. The synergy between the lexicometric method and the general typology is one of the main contributions of this thesis’s heuristics to develop a typology of Finno-Ugric languages that takes greater account of the contrastivity of structures and their relativism as major categorical traits of interlanguage, resulting more sensitive to empirical and methodological biases that may conceal a large corpus

Abstract:
Cellulose-based materials draw their good mechanical properties from the cellu-lose crystal. Improved understanding of crystal properties could lead to a wider range of applications for cellulose-based materials, Cellulose crystals show high axial Youngs modulus. Cellulose can attain several allomorphic forms which show unique structural arrangements in terms of both intra-molecular and inter-molecular bonding, as well as unit cell parameters and chain packing. Although several studies have confirmed that mechanical tensile properties of cellulose differ between different allomorphic forms, few reports have investigated the deformation mechanisms explaining the differences.In the first part of this thesis, the tensile elastic Youngs modulus of cellulose allo-morphs Iβ, II and III I were calculated under uniform conditions using Molecular Dynamics simulation techniques. As expected, a difference in modulus valuesc ould be observed, and the cooperative nature of energy contributions to crys-tal modulus is apparent. The allomorphs also show large differences in terms of how contributions to elastic energy are distributed between covalent bonds,angles, dihedrals, electrostatic forces, dispersion and steric forces.In the second part of this thesis, the cellulose Iβ and II allomorphs were sub-jected to a more detailed structural study. The purpose was to clarify how the deformation of the central glucosidic linkage between the monomer units depends on the hydrogen-bonding structures. This was carried out by studying simulated vibrational spectra and local deformations in the crystals.The results presented in this thesis confirm the differences in the tensile elastic properties of these cellulose allomorphs. These differences can in part be explained by the different intra-molecular hydrogen bonding patterns between allomorphs. Deformation mechanisms are discussed. The results are in supportof the so called ”leverage effect” proposed in the literature. The present analysis shows significant differences in details of deformation mechanisms compared with previous simpler analyses.

Abstract:
Thesis (M.Sc. (Agriculture)) --University of Limpopo,2008
Cellulose is regarded as the most abundant polymer in nature and the first on which X-ray investigations had been performed, a year after the discovery of diffraction of X-rays on crystalline materials in 1912. It is one of the most abundant and important polymers on the planet. It comprises of four allomorphs, cellulose Iβ, II, III and IV1 and IV2 of which Iβ and II are the most stable and industrially important. Cellulose I is the native form of cellulose. Molecular dynamics (MD) simulations have been carried out to study the structural and mechanical properties of cellulose, cellulose Iβ, II, III and IV1 and IV2 bulk systems. Simulations were carried out using Polymer Consistence Force Field (PCFF) and Compass force field in conjunction with the Discover simulation program at various temperatures. We used molecular dynamics simulation to obtain a better insight about temperature dependence of cellulose. Further investigations on mechanical properties of this material at various temperatures were carried out. Using pair correlation functions g(r) or radial distribution functions (rdf’s) we were able to investigate phase transitions wherein as the temperature was increased we observed peak broadening. These enabled us to study the similarities between the structures investigated. Also studied was water uptake in celluloses by way of introducing water at different concentrations. Analysis of lattice parameters compared reasonably well with the experimental. Lattice parameters were calculated using PCFF and they compared well with results found using Compass force field. Calculation of temperature and pressure dependence on bulk systems has been done and it was noted that as the pressure increases the lattice parameters decrease.

Full text
Abstract:
Inflectional classes are an instance of autonomous morphology, where expression in form cross-cuts syntactically relevant distinctions. However, most analyses assume some kind of ‘containment’, where choice of inflectional allomorphs is largely restricted to a part of speech. In default inheritance accounts of morphology higher defaults are assumed to correspond to recognizable parts of speech. Data from Archi and Noon indicate that violations of containment are not so implausible, but even here there is a role for principles, such as Network Morphology’s ‘morphological projection’, or Spencer’s ‘morpholexically coherent lexicon’, that entail a relationship between parts of speech and default morphological classes.

Full text
Abstract:
This chapter develops an explicit theory of vowel harmony based on unary elements and lateral and positional licensing which is embedded in a general dependency-based theory of phonological structure (called ‘Radical CV Phonology’). Harmony is analyzed in terms of a licensing requirement, which results in ‘agreement’, both intra-morphemically and inter-morphemically, that is, within the domain of the word In essence, the view put forward is that lexical vowel harmony involves the selection of lexically listed allomorphs. Licensing will be the selection mechanism for the proper allomorph. The chapter discusses the treatment of morpheme-internal harmony, trigger and targets in harmony, and the notion of cyclicity.

Full text
Abstract:
This chapter identifies a pattern of morphomically distributed root allomorphy—distributed historically, but no longer associated with the perfect aspect of the Latin verb. The allomorphs show a wide variety of phonological forms but they consistently distributed over all and only the tense forms that locally survive from the Latin perfective. The pattern, labelled ‘PYTA’, is repeatedly defended against morphological innovations liable to compromise its integrity, and repeatedly provides the model for a wide range of different morphological innovations. The status of apparent counetrexamples (notably in Aragonese and Aromanian) is explored. The possibility that in Daco-Romance the distributional pattern retains a residual semantic motivation in terms of ‘anteriority’ is examined.

Full text
Abstract:
The chapter outlines a formal theory of inferential-realizational morphology that eliminates (ordered) rule blocks. I show that rule blocks not only stand in the way of a more general treatment of variable morphotactics, but that they also artificially restrict the scope of Pāṇinian competition, effectively ruling out operation at a distance. Instead, it argues for a purely information-based model of global competition that reconciles competition with extended exponence by means of a distinction between realization and allomorphic conditioning. It shows, in particular, that arbitrary decisions with respect to this distinction can be eliminated, once Carstairs’s (1987) notion of Pure Sensitivity has been turned into a formal principle of our theory. Finally, the chapter shows how Information-based Morphology can account for symmetric cases of extended exponence by simultaneous introduction of exponents since the theory is able to capture many-to-many relations between form and function at the level of individual rules.

Full text
Abstract:
Nivkh (Paleosiberian group), spoken on the lower reaches of the Amur River and on Sakhalin island in Siberia by a few hundred speakers in four main varieties, but rapidly dying out, is a polysynthetic head-marking but configurational SOV language, with defective polypersonalism, noun incorporation, verb root serialization, and complex noun forms. Its dominant structural principle and characteristic design is dependent-head-synthesis, with dependents lexically head-marked and still referentially active. Nivkh displays compositional polysynthesis with a mixed internal structure, as the suffixal domain of a word-form may be described by a template, whereas the pre-root domain is scope-ordered due to dependent chaining. The evolutionary path of complex forms is best conceived of as coalescence of formerly adjacent words. Morphophonemic processes at the word-internal morpheme boundaries, especially consonant dissimilation and assimilation, and bound allomorphs prove the wordhood of the complexes. Non-root bound morphemes encode modalities, degree, scalar, and focus operators and phase of action.

Full text
Abstract:
This paper offers a new perspective on the derivation and distribution of nominalised adjectives in Gã. It claims that they are formed by combining an adjectival base and the nominaliser morpheme e‑. Observing that the nominaliser has a variant, the paper argues that the occurrence of the two allomorphs is phonologically constrained. In respect of their distribution, the paper argues that properties like number and agreement marking and co-occurrence with determiners suggest that they are true nominals. Nonetheless, we can clearly distinguish them from other morpho-syntactic units in similar structural positions. The paper also provides new empirical insights for reassessing hitherto assumptions about the distribution of such nominals, including their ability to occur as complement of copulas and depictives.

Full text
Abstract:
Many varieties of Arabic have one or more pre-verbal imperfect markers. While some, like the Egyptian future prefix ħa- or ha-, have a clearly profiled meaning, many defy simple definition. We concentrate on two of these with numerous shared attributes: Iraqi da- and an Upper Egyptian morpheme with many allomorphs conventionally identified as ʕan-. Using corpora of Iraqi and Upper Egyptian Arabic, we describe the syntax-pragmatics of da- and ʕan-, highlighting their pragmatic, procedural basis: both basically signal text coherency. Da- encompasses a global scope while ʕan- is typically used locally in an adjacency pair. We conclude by developing a rough typology of pre-verbal imperfect markers in Arabic, da- and ʕan- constituting a hitherto neglected class of pragmatic prefixes.

Full text
Abstract:
Spanish verbs derived via prefixation prescriptively retain the morphological complexity of their root verbs. However, some verbs derived from decir and hacer show allomorphic variation in the future and conditional, which is documented by the RAE for decir but not at all for hacer. The results of this study of historical variation suggest decreased morphological transparency of some verbs but not of others. Verbs derived from hacer continue to resist regularization, with the notable exception of satisfacer. The set of decir-derived verbs is much more complex in its tendencies. This may be attributable to either (a) perceived opacity of contradecir or (b) increased analogical pressure from maldecir and bendecir which are completely regularized in modern usage. The presence of regularized bendecir and its possible effects on etymologically related verbs contrasts with the resistance of regularization of hacer-derived verbs and the consequent absence of analogical pressure.
