Noun Phrases in L2 French and Haitian: Clues on the Origin of Plantation Creoles

Patrick-Andre Mather 세종대학교 언어연구소 2005 Journal of Universal Language Vol.6 No.2

This article provides evidence from studies on second language acquisition in support of the gradualist model of creole genesis. According to this model, creole genesis is viewed as a gradual process away from the lexifier language, as successive generations of African slaves acquired increasingly divergent varieties of the emerging contact language. This article provides examples on the L2 acquisition of French, and compares interlanguage structures with Haitian, a radical French-lexifier creole. Using examples within the NP domain, I conclude that many creole features can be accounted for in terms of second language acquisition, either as 1) the transfer of L1 features (via e.g., relexification), 2) the acquisition of L2 features, or 3) interlanguage structures found neither in the L1 or the L2, including innovations (e.g., reanalysis or grammaticalization) or other developmental stages in second language acquisition. The article also discusses the origin of tense-mood-aspect markers, which are not attested in the L2 data and may be better explained in terms of first, rather than second language acquisition processes.

SOCIAL INVOLVEMENT AND CONSUMPTION MOTIVATION: CO-CREATION OF MAGIC IN THE BAR SERVICESCAPE

Lisa McNeill,Damien Mather 글로벌지식마케팅경영학회 2016 Global Marketing Conference Vol.2016 No.7

In service experiences, customers often look to create their own magic in the service environment, through interaction with other customers, not the producer of the experience (the provider) at all. The current study examines the bar environment, where hedonically-driven service encounter experiences are constructed, not by the provider, but by the social interactions of the consumers of the environment. The study surveys 130 consumers, measuring experiential, situational and social involvement levels in relation to consumption motivation and overall experience evaluation. The research finds that, while bar consumers are likely to be highly socially involved, they still need the company of close friends to become fully involved in the bar service experience. In addition, where atmospheric theory discusses the value of extraordinary or surprising service environments, consumers in the already hedonic bar environment may indeed prefer environments which are simply comfortable and consistent with their expectations (in regard to motivations to consume and overall positive evaluations).

Short Communication : Inheritance of Grain Filling Duration in Spring Wheat (Triticum aestivum L. em Thell)

( Kamaluddin ),( Rishi Muni Singh ),( Malik Zainul Abdin ),( Mather Ali Khan ),( Tanweer Alam ),( Salim Khan ),( Lal Chand Prasad ),( Arun Kumar Joshi ) 한국식물학회 2007 Journal of Plant Biology Vol.50 No.4

To understand the genetic control of grain filling duration (GFD), i.e., the number of days from anthesis to physiological maturity, we studied the F1, F2, BC1 and BC2 generations of six spring wheat crosses from nine varieties/genotypes. Generation mean analysis for gene effects indicated that one or more types of epistasis were significant in all crosses. In each pairing, the F1 and F2 means were either intermediate or closer to the mean of the parent having the longer GFD. Our narrow-sense heritability estimate was reasonably high, at 47.67 (based on diallel analysis). This demonstrated that progress could be made from the selection in these crosses for either long or short GFD. The two early varieties that had identical maturity durations differed in their GFD values, indicating that maturity dates are not good criteria when choosing parents for modifying GFD. To utilize favorable additive × additive effects during this selection, we suggest that a single seed descent (SSD) or bulk opulation approach be adopted. In comparison, dominance effects would prove quite useful in hybrid wheat breeding programs.

Field experiments were conducted to determine the physiological and biochemical basis of the interactive effect of sulphur (S) and nitrogen (N) application on seed and xanthotoxin yield of Ammi majus L. Six treatments were tested ($T_1$ = control-without manure and fertilizers, $T_2$ = manure @ 9 kg $plot^{-1}-10\;t\;ha^{-1},\;T_3=A_0N_{50}K_{25}P_{25},\;T_4=S_{40}N_{50}K_{25}P_{25},\;T_5=S_{40}N_{100}K_{25}P_{25}\;T_6=S_{20+20}N_{50+50}K_{25}P_{25})$). Nitrate reductase (NR) activity and ATP-sulphurylase activity in the leaves were measured at various phonological stages, as the two enzymes catalyze rate-limiting steps of the assimilatory pathways of nitrate and sulphate, respectively. The activities of these two enzymes were strongly correlated with seed and xanthotoxin yield. The highest nitrate reductase activity, ATP-sulphurylase activity and xanthotoxin yield were achieved with the treatment $T_4$. Any variation from this treatment decreased the activity of these enzymes, resulting in a reduction of the seed and xanthotoxin yield in Ammi majus L. The higher seed and xanthotoxin yield achieved in Ammi majus L. at treatment $T_4$ could be due to optimization of leaf soluble protein and photosynthetic rate, as these parameters are Influenced by S and N assimilation.

Poly(vinyl alcohol) (PVA)/sulfonated polyhedral oligosilsesquioxane (sPOSS) hybrid membranes for direct methanol fuel cell applications

Chang, Young-Wook,Wang, Erdong,Shin, Geumsig,Han, Jung-Eun,Mather, Patrick T. JOHN WILEY & SONS LTD 2007 POLYMERS FOR ADVANCED TECHNOLOGIES Vol.18 No.7

<P>Organic/inorganic hybrid membranes based on poly(vinyl alcohol) (PVA) and sulfonated polyhedral oligosilsesquioxane (sPOSS), crosslinked by ethylenediaminetetraacetic dianhydride (EDTAD), were prepared as candidate materials for proton exchange membranes in direct methanel fuel cell (DMFC) applications. Fourier transform infrared (FT-IR) spectroscopy and ion exchange capacity measurements for the prepared networks clearly revealed sPOSS incorporation. We found that proton conductivity increased and methanol permeability decreased with increasing sPOSS content in the hybrid membrane. In particular, our hybrid membranes demonstrated proton conductivities as high as 0.042 S/cm, which is comparable to that of Nafion™, while exhibiting two orders of magnitude lower methanol permeability as compared to Nafion™. We postulate that the polar sulfonic acid groups of the incorporated sPOSS cages assemble to provide ion conduction paths while the hydrophobic portions of the same sPOSS cages combine to form a barrier to methanol permeation with improved thermal stability of the hybrid membrane.

Molecular Composite Coatings on Nafion Using Layer-by-Layer Self-Assembly

Lefaux, Christophe J.,Kim, Byoung-Suhk,Venkat, Narayanan,Mather, Patrick T. American Chemical Society 2015 ACS APPLIED MATERIALS & INTERFACES Vol.7 No.19

<P>Controlled growth of nanometer-scale multilayered coatings of negatively charged sulfonated poly(benzobisimidazole) (SPBI), complexed with positively charged poly(2-vinylpyridine) (P2VP) on quartz, and Nafion membrane as substrates has been explored. Both polymers, SPBI and P2VP, possess a net charge in methanol as a result of the dissolution of SPBI by complexation with triethylamine (TEA) and the protonation of P2VP with HCl, respectively, and thereby can form a multilayered molecular composite of alternating anionic SPBI and cationic P2VP via an electrostatic layer-by-layer (LbL) self-assembly. UV–vis absorption spectrophotometry was used to monitor the buildup and growth rate of such SPBI/P2VP multilayer films. Atomic force microscopy (AFM) was used to determine the roughness and thickness of the resulting SPBI/P2VP multilayers. As a result, it was found that a steady-state linear growth regime for the LbL self-assembled SPBI/P2VP multilayer films and coatings onto quartz and Nafion membranes was observed after completion of the first few deposition cycles, indicating the successful formation of the SPBI/P2VP multilayered assembly in methanol solutions. In addition, the SPBI/P2VP multilayer films in the perpendicular direction (flat view) demonstrated isotropic orientation distribution on the Nafion membrane, while the SPBI/P2VP multilayer films examined by X-ray scattering in the parallel direction (edge view) revealed anisotropic orientation, the combined observations indicating confinement of SPBI rods to the plane of the coating. We further found that the SPBI/P2VP multilayer coated Nafion possesses good thermal stability, as indicated by isothermal gravimetric analysis at 310 °C, and it was further observed that SPBI/P2VP multilayer coatings using the LbL self-assembly technique on Nafion membrane significantly increased the membrane stiffness, despite the small coating thickness employed.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/aamick/2015/aamick.2015.7.issue-19/acsami.5b01371/production/images/medium/am-2015-01371j_0010.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/am5b01371'>ACS Electronic Supporting Info</A></P>
