This paper proposes a representation for syllable structure in HPSG, building on previous work by Bird and Klein (1994), Höhle (1999), and Crysmann (2002). Instead of mapping segments into a a separate part of the sign where syllables are represented structurally, information about syllabification is encoded directly in the list of segments, the core of the PHONOLOGY value. Higher level prosodic phenomena can operate on a more abstract representation of the sequence of syllables derived from the syllabified segments list. The approach is illustrated with analyses of some word-boundary phenomena conditioned by syllable structure in French.

Privileged Status

The following pages sketch a system of constraints intended to sharpen and organize a number of current assumptions surrounding the concept of “prosodic licensing”, as proposed in Itô (1988) and further developed in later work (Bagemihl 1991; Charette 1990; Goldsmith 1990; Inkelas 1991; Itô and Mester 1991; Kaye 1990; Lombardi 1991; Piggott 1991; Zec 1988; and others). The proposal to be developed below draws on Optimality Theory (Prince and Smolensky 1993); one of the goals is to explicate the notion of the coda as a “secondary licenser” (Goldsmith 1990) and to clarify the privileged status of geminate and partial geminate clusters (Prince 1984) with respect to syllabification. After laying out some background assumptions (Section 1), we present the definitions and constraints that form the core of our theory of licensing (Section 2). We illustrate the approach with an analysis of the syllable structure of Japanese (Section 3) and conclude the paper with a discussion of remaining issues and problems relating to the general typology of syllabification systems (Section 4).

Invariant Shape

This article introduces two phenomena that are studied within the domain of templatic morphology—clippings and word-and-pattern morphology, where the latter is usually associated with Semitic morphology. In both cases, the words are of invariant shape, sharing a prosodic structure defined in terms of number of syllables. This prosodic template, being the core of the word structure, is often accompanied with one or more of the following properties: syllable structure, vocalic pattern, and an affix. The data in this article, drawn from different languages, display the various ways in which these structural properties are combined to determine the surface structure of the word. The invariant shape of Japanese clippings (e.g., suto ← sutoraiki ‘strike’) consists of a prosodic template alone, while that of English hypocoristics (e.g., Trudy ← Gertrude) consists of a prosodic template plus the suffix -i. The Arabic verb classes, such as class-I (e.g., sakan ‘to live’) and class-II (e.g., misek ‘to hold’), display a prosodic template plus a vocalic pattern, and the Hebrew verb class-III (e.g., hivdil ‘to distinguish’) displays a prosodic template, a vocalic pattern and a prefix. Given these structural properties, the relation between a base and its derived form is expressed in terms of stem modification, which involves truncation (for the prosodic template) and melodic overwriting (for the vocalic pattern). The discussion in this article suggests that templatic morphology is not limited to a particular lexicon type – core or periphery, but it displays different degrees of restrictiveness.

Its Analysis

In this paper, attention is on the basic factors that come into force in determining whether or not vowel will elide and which of the V1 and V2 in a sequence should disappear in any environment. This paper also examines the phonological, morphological and syntactic reasons behind vowel elision as a syllable structure process in Ikhin language. As in the case of related African languages that have been previously described by various scholars, this paper presents how vowel elision works in Ikhin and the problems arising from its analysis. In this study, the focus is on the explanation and analysis of factors such as boundary, morpheme structure and vowel quality which actually determine whether or not elision should take place in Ikhin. Apart from factors such as vowel quality and boundary, one other factor with respect to elision or glide formation is the syllable structure of the verbs and nouns in Ikhin. Ikhin nouns are either disyllabic i.e. V(C)V or trisyllabic, etc. It is argued that the operation of vowel elision is blocked in disyllabic nouns as /i/, /o/ and /u/ form glides when either of them occurs as V1 whereas vowel elision rather than glide formation takes place in trisyllabic nouns. The study concludes based on data not previously discussed in the language that elision is driven by syllable-based and syntactic-based analyses and that a major strategy of discouraging vowel cluster in Ikhin is vowel elision because the syllable structure of the language prohibits cluster of vowels within word or across word boundary.

Structure Changes

One of the syllable structure changes that occur in rapid speech because of sounds influencing each other is elision. This paper provides an account of elision in Esahie, also known as Sehwi, a Kwa language spoken in the Western North region of Ghana. The paper discusses the processes involved in elision, and the context within which elision occurs in the language. The paper shows that sound segments, syllables and tones are affected by the elision process. It demonstrates that elision, though purely a phonological process, is influenced by morphological factors such as vowel juxtapositioning during compounding, and at word boundary. The evidence in this paper show that there is an interface between phonology and morphology when accounting for elision in Esahie. Data for this study were gathered from primary sources using ethnographic and stimuli methods.

Pitch Accents

This paper examines the phonetic realization of rising pre-nuclear pitch accents in Persian. In a first experiment, the alignment of f0 valleys and peaks in pre-nuclear pitch accents was analyzed in controlled speech materials as a function of the syllable structure (open vs. closed) and vowel type (short vs. long) of the accented syllable. The results revealed that in words with antepenultimate stress, both the L and the H tones are anchored to specific segmental landmarks irrespective of syllable structure or vowel type. In particular, the L is consistently aligned with the onset of the accented syllable, and the H is placed with similar consistency in the vicinity of the first post-accentual vowel. In a second experiment, the variability in the timing and scaling of L valleys and H peaks was examined as a function of the proximity of the word boundary and of the following accent. The results revealed that while the alignment of the L was unaffected by changes in stress conditions, H peaks were significantly retracted as the syllable approached the end of the word. However, the proximity of the following accent did not produce a significant effect on H alignment. In addition, no significant differences were found on L and H scaling in different stress or tonal crowding conditions. Overall, the results contribute to a growing body of evidence that in the absence of upcoming prosodic pressure, the alignment of pitch targets is specified relative to segmental positions. A comparison between these findings and empirical findings from other languages reveals fine phonetic differences of segmental anchoring that are less likely to be interpreted in terms of distinct association-based phonological representations, and suggests that some aspects of segmental anchoring need to be explained in terms of continuous language-specific alignment rules.

A business model by definition is an abstract representation of the business logic of a firm and as such encapsulates the core aspects of a firm. Business model ideation is a sequential process composed of three precursors - surveying the technological landscape, identifying and incorporating customer outcomes, identifying and incorporating business requirements. These precursors serve as key inputs to the final business model ideation phase. This paper focuses onthe third precursor, identifying and incorporating business requirements into the business model,and this is termed as developing the business perspective.The paper consists of three sections. The first section explores the concept of business requirements - what it is and how to identify business requirements. The second section explores the concept of business model. Specifically, it will focus upon the concept of business model as defined in the Business Model Ontology. The final section details out how to develop the business perspective i.e. explicates methodology by which business requirements can be incorporated into the business model of a firm using Solution Summary matrix, Solution Comparison matrix and the Solution Canvas.

Abstract The target article carefully describes the memory system, centered on the temporal lobe that builds specific memory traces. It does not, however, mention the laterality effects that exist within this system. This commentary briefly surveys evidence showing that clear asymmetries exist within the temporal lobe structures subserving the core system and that the right temporal structures mainly underpin face familiarity feelings.

The authors have investigated the dissolution process of human cholesterol gallstones using a scanning electron microscope(SEM). This study was carried out by comparing control gallstones incubated in beagle bile with gallstones obtained from patients who were treated with chenodeoxycholic acid(CDCA).The cholesterol gallstones for this study were obtained from 14 patients. Three control patients were treated without CDCA and eleven patients were treated with CDCA 300-600 mg/day for periods ranging from four to twenty five months. It was confirmed through chemical analysis that these gallstones contained more than 80% cholesterol in both the outer surface and the core.The specimen were obtained from the outer surface and the core of the gallstones. Each specimen was attached to alminum sheet and coated with carbon to 100Å thickness. The SEM observation was made by Hitachi S-550 with 20 kV acceleration voltage and with 60-20, 000X magnification.

The fat body of insects has always been compared functionally to the liver of vertebrates. Both synthesize and store glycogen and lipid and are concerned with the formation of blood proteins. The comparison becomes even more apt with the discovery of microbodies and the localization of urate oxidase and catalase in insect fat body.The microbodies are oval to spherical bodies about 1μ across with a depression and dense core on one side. The core is made of coiled tubules together with dense material close to the depressed membrane. The tubules may appear loose or densely packed but always intertwined like liquid crystals, never straight as in solid crystals (Fig. 1). When fat body is reacted with diaminobenzidine free base and H2O2 at pH 9.0 to determine the distribution of catalase, electron microscopy shows the enzyme in the matrix of the microbodies (Fig. 2). The reaction is abolished by 3-amino-1, 2, 4-triazole, a competitive inhibitor of catalase. The fat body is the only tissue which consistantly reacts positively for urate oxidase. The reaction product is sharply localized in granules of about the same size and distribution as the microbodies. The reaction is inhibited by 2, 6, 8-trichloropurine, a competitive inhibitor of urate oxidase.

Grains of pigeonite, a calcium-poor silicate mineral of the pyroxene group, from the Whin Sill dolerite have been ion-thinned and examined by TEM. The pigeonite is strongly zoned chemically from the composition Wo8En64FS28 in the core to Wo13En34FS53 at the rim. Two phase transformations have occurred during the cooling of this pigeonite:- exsolution of augite, a more calcic pyroxene, and inversion of the pigeonite from the high- temperature C face-centred form to the low-temperature primitive form, with the formation of antiphase boundaries (APB's). Different sequences of these exsolution and inversion reactions, together with different nucleation mechanisms of the augite, have created three distinct microstructures depending on the position in the grain.In the core of the grains small platelets of augite about 0.02μm thick have farmed parallel to the (001) plane (Fig. 1). These are thought to have exsolved by homogeneous nucleation. Subsequently the inversion of the pigeonite has led to the creation of APB's.
