Simplifying a system: a story of language change in Lelepa, Vanuatu

This paper focuses on the problem posed by the vowel surfacing during two encliticization processes in Lelepa (Oceanic, Vanuatu), with the nominalizer =na ‘NMLZ’ and the pronominal =s ‘OBL’. For instance, the verbs faam ‘eat’, mat ‘dead’ and fan ‘go:IRR’ are derived as nafaamina ‘food’, nmatena ‘funeral’ and nafanona ‘departure’. While the base forms have the same vowel /a/, those vowels surfacing before =na seem unpredictable. This paper discusses several possible explanations for these vowels and shows that both historical and phonological approaches are needed to account for them. Still, there is variation in the nominalisation of certain native verbs such as raik ‘fish with hand spear’, which is derived as either naraikana or naraikina ‘hand spear fishing’. It is shown that while naraikana is accounted for in diachrony, naraikina results from a reanalysis process indicated by intergenerational variation.ANU College of Arts & Social Sciences, School of Language Studies; ANU College of Asia and the Pacific, School of Culture, History and Languag

Possession in Lelepa, a language of Central Vanuatu

This thesis studies possession in Lelepa, a language from the Oceanic subgroup of Austronesian, spoken in Central Vanuatu. Investigating this particular feature of the language was achieved by collecting original data from Lelepa speakers. Language data is presented in the form of interlinearised examples taken from a corpus of texts and elicitation notes. Data was collected between 2006 and 2008 during fieldtrips to Lelepa and Mangaliliu. The core of the study is devoted to the possessive system of Lelepa. Like many other Oceanic languages, Lelepa has direct and indirect possessive constructions. This thesis shows that the direct possessive construction formally consists of a possessed noun to which a possessor suffix attaches. It encodes possession of semantic domains such as body parts, body products, reference kinship terms, items closely associated to the possessor and parts of wholes. Indirect possession is expressed by two distinct subtypes: the free and construct indirect constructions. The free indirect construction has pronominal possessors only, encoded by two distinct pronoun paradigms: general and part-whole possession pronouns. The former pronouns are used for possession of items that normally do not occur in the direct construction, and the latter are used for possession of parts of wholes. The construct indirect construction is characterised by the occurrence of either of two construct suffixes, -n or -g. The -n construct indirect construction has pronominal and nominal possessors, and the same semantic scope as the direct construction. The -g construct indirect construction has nominal possessors only, and the same semantic scope as the free indirect construction with general possession pronouns. This study also demonstrates that free variation between two possessive constructions, the direct construction and the -n construct indirect construction with pronominal possessors, occur in the language, although more work is needed to determine the scope of this feature

The languages of Vanuatu: Unity and diversity

With an estimated 138 different indigenous languages, Vanuatu is the country with the highest linguistic density in the world. While they all belong to the Oceanic family, these languages have evolved in three millennia, from what was once a unified dialect network, to the mosaic of different languages that we know today. In this respect, Vanuatu constitutes a valuable laboratory for exploring the ways in which linguistic diversity can emerge out of former unity. This volume represents the first collective book dedicated solely to the languages of this archipelago, and to the various forms taken by their diversity. Its ten chapters cover a wide range of topics, including verbal aspect, valency, possessive structures, numerals, space systems, oral history and narratives. The languages of Vanuatu: Unity and Diversity provides new insights onto the many facets of Vanuatu’s rich linguistic landscape

Un monde ouvert sur l’extérieur : mobilité et migrations dans l’élection de Poitiers au xviiie siècle

L’observation croisée des rôles de taille et des registres de translation de domicile aboutit à distinguer les rythmes et les caractéristiques sociales des migrations dans le Poitou rural du xviiie siècle. Le ralentissement de la mobilité à la fin du siècle se confirme, de même que l’effet amplificateur des crises de subsistances sur l’instabilité des professions les plus humbles, en particulier lors du grand hiver de 1709-1710. D’une façon générale, la mobilité est plus marquée chez les journaliers, les domestiques et les petits artisans temporaires du textile, mais aussi parmi certaines catégories plus bourgeoises, comme les chirurgiens. On constate, en revanche, un enracinement des laboureurs qui se renforce au cours du siècle et une importante stabilité des métiers au cœur de la vie communautaire, comme les maréchaux ou les cabaretiers.The cross observation of the rôles de taille et des registres de translation de domicile lead to distinguish the rhythms and social caracteristics of the migrations in the rural Poitou of the 18th Century. The slowing-down of the mobility at the end of the century confirms itself, as well as amplificating effects of sustenance crisis upon the instability of the humblest professions, especially during the great winter of 1709-1710. Generally speaking, mobility is more pronounced on day-labourers, servants and small temporary craftsmen of the textile industry, but also among richer social categories like surgeons. On the other hand a deep-rooting of labourers that is being renforced during the century and an important stability of trades at the heart of the community can be noted, like smiths or tavern-keepers

Lelepa: topics in the grammar of a Vanuatu language

This thesis discusses topics in the grammar of Lelepa, an Oceanic language spoken by about 500 people on the islands of Lelepa and Efate in the centre of the Vanuatu archipelago. The areas of grammar covered in the thesis are phonology (chapter 2), morphology (chapter 3), word classes (chapter 4), noun phrases (chapter 5), possession (chapter 6), clause structure and grammatical relations (chapter 7), verb classes and valency changing devices (chapter 8), the verb complex (chapter 9), complex predicates (chapter 10), aspect and modality (chapter 11), coordination and subordination (chapter 12). The phonemic inventory is of medium to small size, with fourteen consonants and five vowels. It includes two typologically rare labial-velar consonants. Stress is not phonemic. Syllables can be complex and consonant clusters are allowed in onset and coda positions. The most important phonological process is vowel reduction, which represent a significant driver of language change. Clausal word order is SVO. Oblique arguments follow the object(s), and adjuncts occur in initial or final position in the clause. An exception is the benefactive phrase, an adjunct encoding beneficiaries which occurs between the subject proclitic and the verb, and makes the verb complex a discontinuous structure. The benefactive phrase is cross-linguistically unusual and makes central Vanuatu languages distinctive. Of typological interest is the split dividing objects along two classes of transitive verbs. It has its source in a semantic distinction between significantly affected Ps and less affected Ps. However, the split is lexical because borrowed transitive verbs are systematically classified with verbs taking less affected Ps regardless of the degree of affectedness of their P. Lelepa has serial verb constructions but has also developed other verbal constructions grouped in the class of complex predicates, which comprise auxiliary verbs, serial verbs, post-verbs and viii clause-final particles. These encode a broad range of semantic distinctions including aspectual, modal and directional values, manner, intensification, cause-effect and result. Lelepa distinguishes between inalienable and alienable possession, but the possessive constructions have diverged from the typical Oceanic model. In particular, relational classifiers are not found in the language, and a construction reflecting alienable relationships distinguishes between human and non-human possessors. An unusual feature is the marking of mood and transitivity on certain verbs with Stem Initial Mutation. In this process, verbs switch their initial consonant from /f/ to /p/ according to particular mood and transitivity values. This process is known in Vanuatu language but often limited to mood marking, whereas Lelepa and other central Vanuatu languages also mark transitivity. The morphological structure is agglutinative, but many grammatical features are encoded by particles, especially in the verb complex. In the nominal domain, inflectional affixes include possessor-indexing suffixes, a prefixed article and derivational affixes generating deverbal nouns. Compounding is a feature of both nouns and verbs. Word classes are clearly defined, and the main open classes are nouns and verbs. Nominals can be derived through nominalisation of verb roots or substantivisation, a process deriving referential items from all word classes except nouns and pronouns

Diazo Compounds and Phenyliodonium Ylides in Inter- and Intramolecular Cyclopropanations Catalyzed by Dirhodium(II). Synthesis and Chiral Resolution by GC versus HPLC

Summary.: The dirhodium(II)-catalyzed intermolecular cyclopropanation of a set of olefins with either diazo free phenyliodonium ylides or diazo compounds afforded cyclopropanes derived from Meldrum's acid, dimethyl malonate, (silanoxyvinyl)diazoacetates, 3,3,3-trifluoro-2-diazopropionate, ethyl diazo(triethyl)- and (dimethylphenyl)silylacetate with moderate to high yield in either racemic or enantio-enriched forms. The intramolecular cyclopropanation of triethylsilyl-substituted allyl diazoacetates in the presence of the chiral rhodium(II) catalyst [Rh2(s-nttl)4] in toluene afforded the corresponding cyclopropanes with up to 37% ee. An efficient chiral separation method based on enantioselective GC and HPLC was developed. The method provides information about the chemical yields of the cyclopropane products, enantioselectivity, substrate specifity, and catalytic activity of the chiral catalysts used in the inter- and intramolecular cyclopropanation reactions and avoids time-consuming work-up procedure

Enantioselective Gas Chromatographic Analysis of Cyclopropane Derivatives

Chirasil-β-Dex was used as chiral stationary phase for the enantioselective gas chromatographic analysis of several new chiral cyclopropane derivatives. The GC method provides information about the chemical yields of the cyclopropane products, enantioselectivity, substrate specifity, and catalytic activity of the chiral catalysts used in the inter- and intra-molecular cyclopropanation reactions and avoids time-consuming work-up procedure

Simultaneous plasticization and blending of isolated soy protein with poly(butylene succinate-co-adipate)

International audienceAgrarian proteins, due to their good film forming properties, moderate cost, and biodegradable nature, have been extensively studied to develop affordable packaging materials. However, when compared to conventional polymers, isolated proteins based polymers have poor mechanical and barrier properties. Blending with others polymers seems to be a viable option to overcome these issues. The present work focuses on the preparation of isolated soy protein (ISP) / poly[(butylene succinate)-coadipate] (PBSA) blends with different ratios by extrusion and injection moulding using glycerol and water mixture as plasticizer. PBSA is bio-based, biodegradable, and its relatively low melting point is compatible with the processing temperature of ISP. Two different processing strategies were used and compared for the preparation of blends. In the novel single step approach, ISP, plasticizers (glycerol and water) and PBSA are dry mixed and extruded all together in a co-rotating twin-screw extruder. In the regular two-step approach, plasticized protein is prepared by extrusion of ISP with a glycerol/water mixture, followed by a second extrusion step of plasticized protein with PBSA. Prepared blends were characterized for their morphology, thermal, dynamic mechanical and mechanical properties. The mechanical properties of the blends prepared by single step process are roughly similar to those produced by two-step process; this indicates the efficiency of one-step melt processing of PBSA with isolated soy protein involving plasticization, denaturation, melt-melt mixing and morphology development in the extruder, this compounding method being moreover less time consuming

The yield and isotopic composition of radiolytic H2, a potential energy source for the deep subsurface biosphere

Author Posting. © The Authors, 2004. This is the author's version of the work. It is posted here by permission of Elsevier B.V. for personal use, not for redistribution. The definitive version was published in Geochimica et Cosmochimica Acta 69 (2005): 893-903, doi:10.1016/j.gca.2004.07.032.The production rate and isotopic composition of H2 derived from radiolytic reactions in H2O were measured to assess the importance of radiolytic H2 in subsurface environments and to determine whether its isotopic signature can be used as a diagnostic tool. Saline and pure, aerobic and anaerobic water samples with pH values of 4, 7 and 10 were irradiated in sealed vials at room temperature with an artificial γ source, and the H2 abundance in the headspace and its isotopic composition were measured. The H2 concentrations were observed to increase linearly with dosage at a rate of 0.40 ± 0.04 molecules (100 eV)-1 within the dosage range of 900 to 3500 Gray (Gy; Gy =1 J Kg-1) with no indication of a maximum limit on H2 concentration. At ~2000 Gy, the H2 concentration varied only by 16% across the experimental range of pH, salinity and O2. Based upon this measured yield and H2 yields for α and β particles a radiolytic H2 production rate of 10-9 to 10-4 nM sec-1 was estimated for the range of radioactive element concentrations and porosities typical of crustal rocks. The δD of H2 (δD = ((D/H)sample/(D/H)standard –1) × 1000) was independent of the dosage, pH (except for pH 4), salinity, and O2 and yielded an αDH2O-H2 of 2.05 ± 0.07 (αDH2O-H2 = (D/H)H2O to (D/H)H2), slightly less than predicted radiolytic models. Although this radiolytic fractionation value is significantly heavier than that of equilibrium isotopic exchange between H2 and H2O, the isotopic exchange rate between H2 and H2O will erase the heavy δD of radiolytic H2 if the age of the groundwater is greater than ~103 to 104 years. The millimolar concentrations of H2 observed in the groundwater of several Precambrian Shields are consistent with radiolysis of water that has resided in the subsurface for a few million years. These concentrations are well above those required to support H2-utilizing microorganisms and to inhibit H2-producing, fermentative microorganisms.This work is supported by grant from NSF LExEn program (EAR-9978267) to T.C.
