This paper analyses the phenomenon of Suspended Affixation (SA) which refers to a situation in coordinated constructions when affixes on the final conjunct have scope over all the non-final conjuncts. The main goal of this paper is to look at the structure of SA for Noun Compound Coordination and to find out how pl and poss suffixes behave regarding suspension. Previous studies have shown that in N and NP coordination poss cannot be suspended leaving pl on the non-final conjunct. This study tests the suspendability of poss in the context of Noun Compound coordination. Since SA seems to represent gradient judgment data two acceptability judgment studies were conducted to find out the (un)grammaticality of Noun Compound constructions. The results show that pl and poss suffixes cannot be suspended for independent reasons. The suspendability of poss does not depend on the presence/absence of pl in the structure due to its structural position. This article proposes an analysis of SA in N and NP coordination which represents a combination of two approaches on SA already proposed in literature and is based on the idea of Parallel Merge proposed by Citko (2005). SA in N and NP coordination is considered to be a coordination of fully inflected conjuncts where the inflections are parallel-merged with two conjuncts (final and non-final). I show that due to the structure of Noun Compound coordination constructions, pl and poss cannot be parallel-merged because of a minimality condition: a non-final conjunct has to be a Minimal Morphological Word.

Ethylene (C₂H₄) production was monitored in twelve desert soils incubated moist at constant temperature for various incubation periods. In all but two soils with high organic matter content, C₂H₄ production was low. Statistical analysis showed a good correlation between organic matter content and C₂H₄ production. Minimum levels of C₂H₄ were observed in saline and sodic soils. Adding ethanol, glucose, glycerol and methionine to soil samples significantly increased C₂H₄ formation. Methionine induced the highest level of C₂H₄ in all soils tested. Increased concentrations of methionine resulted in further significant increases in C₂H₄ production possibly indicating its role as a precursor for C₂H₄. Chloramphenicol did not have a significant effect except in a saline soil suggesting that bacterial C₂H₄ production is of less significance in the other soils. The addition of salts to the high C₂H₄ producing soils suppressed C₂H₄ production most likely because of a direct effect on C₂H₄ producing microorganisms through toxic salt levels, high osmotic pressure and/or increased pH. Leaching of four saline soils and subsequent incubation resulted in significant increases in C₂H₄ in two soils. Ethylene producers, previously inhibited by salinity, were probably reactivated when the salts were removed. A Fusarium isolate obtained from the highest C₂H₄ producing soil, produced the most C₂H₄ in pure culture followed by isolates belonging to the genera Aspergillus, Penicillium, Curvillaria, and Rhizopus. In a comparative study, a number of species, some of which were known to produce C₂H₄, were tested in culture media. Nine species produced C₂H₄ in varying amounts of which Penicillium digitatum produced the highest concentration. A sterilized saline soil produced significant C₂H₄ when inoculated with spores of Mucor hiemalis and the Fusarium isolate, 5 to 14 times that in non-sterilized soil probably indicating an originally low population of C₂H₄ producing organisms. The amounts of C₂H₄ produced in sterilized inoculated mollisol and garden soils were only a fraction of that produced in non-sterilized samples probably indicating the involvement of a number of species in the production of C₂H₄ in these soils.

The sorption of five chlorinated benzenes and sixteen other organic solutes was investigated by determining the extent of sorption and the sorption rates in a series of 40 batch and 139 column experiments using surface-modified silica of known chemical composition. These surfaces were used to represent important functional groups in soil, and consisted of porous silica with patchy surface coatings of aliphatic chains (C₁, C₈, and C₁₈), and other substituent groups (phenyl, amine, alcoholic, and carboxylic). Three possible rate-limiting steps were examined: diffusion through immobile pore fluid, diffusion through bound organic matter, and the chemical binding and release rate. First-order desorption rate coefficients were observed to be 10⁻¹ to 10⁻² s⁻¹ on unbonded, and C₈, C₁₈, amine, and alcoholic modified surfaces, and 10⁻³ to 10⁻⁵ s⁻¹ on C₁ and phenyl-polymer modified surfaces. Diffusion through immobile pore fluid had only a minor effect on the sorption rate, as evidenced by similar rates on organic-bound porous and solid particles. The diffusion rate through the bound organic layer is not rate limiting due to the small organic layer thickness. The observed slow desorption on the phenyl-polymer surface is consistent with the rate limiting step being the chemical binding and release rate. The changes in the rate with temperature and within a series of chlorinated benzenes support this conclusion. The free energies for sorption onto the phenyl-polymer surface ranged from -4.0 kcal mol⁻¹ for chlorobenzene to -6.9 kcal mol⁻¹ for pentachlorobenzene, which are within the range expected for van der Waals interactions. The observed sorption energies are slightly stronger than predicted for hydrophobic surfaces, possibly reflecting strong binding due to multiple pi-pi electron interactions on the phenyl-polymer surface. Hydrophobic solute partitioning onto natural soils, as observed by others, is less than that observed on aliphatic and phenyl hydrophobic surfaces in this study, but greater than on amine or alcoholic modified surfaces. The sorption of di-, tri-, and tetra-chlorobenzenes onto the phenyl-polymer surface is apparently driven by the overall sorption enthalpy (ΔH° = -3.9 to -4.9 kcal mo1⁻¹) and to a lesser extent by the entropy (TΔS° = 0.5 to 1.5 kcal mol⁻¹). As equilibrium of the reactions observed in this study are reached within hours, these reactions are important at small field scales where residence times are hundreds of hours or less.

Helium tracer experiments were conducted to characterize conservative tracer behavior in a wedge-shaped lysimeter containing alternating layers of unsaturated silty sand, and clay loam. Experiments were conducted with trichloroethylene and 1,1,1-trichloroethane to determine if air stripping in unsaturated soil could be characterized by mass transfer from the sorbed to the liquid to the vapor phase. Batch experiments were conducted to measure liquid--vapor mass transfer. Solid-liquid-vapor mass transfer was characterized by measuring the vapor phase re-equilibration after the air stripping experiment. The Discrete State Compartment model was used to simulate a conservative gas tracer. The results were compared to the helium tracer. Liquid-vapor, and solid-liquid-vapor mass transfer were modeled by fitting simulated data to experimental data. The conservative tracer, and mass transfer models were combined to simulate air stripping in unsaturated soil.

The successful application of Tppts, and its derivatives, in biphasic transition metal-catalysed reactions opened up a new field of chemistry requiring a rational design of water-soluble ligands. The main objective of the research described in this dissertation was the preparation and the application of new water-soluble phosphine ligands. The ligands were prepared by the use of carbon nucleophiles and chlorophenylphosphine derivatives. The carbon nucleophiles included malonate derivates, which were subsequently reduced to the di-alcohols and were transformed into water-soluble phosphines by the reaction with 1,4-butanesultone. Secondary and tertiary malonate nucleophiles were used and the steric demands of compounds containing more than one malonate group were investigated. Various attempts to obtain water-soluble compounds from dimalonate phosphine oxides failed. TBDMS-protected aryl halides were also used as nucleophiles. One (or two) of these silyl ethers was reacted with chlorophenylphosphine derivatives and after deprotection with TBAF the compounds were made water-soluble by a reaction with 1,4-butanesultone. The hydrogenation of arylphosphine oxides to form cyclohexylphosphine oxide derivatives was also investigated. However, these cyclohexylphosphines were more easily obtained by the reaction between the previously mentioned carbon nucleophiles and chlorocyclohexylphosphine derivatives, which were freshly prepared. A series of cyclohexyl-containing water-soluble phosphines was prepared in this way. The oxygen sensitive nature of phosphines lead to two different approaches in the reaction route: the phosphines were either borane protected followed by a subsequent deprotection step, or the phosphines were allowed to oxidise and were reduced back to the free phosphine at a later stage. The efficiency of both approaches in the reaction routes was examined. The deprotection of phosphine-boranes was performed using various “new” deprotecting reagents and the borane-species and free phosphines were separated using water/organic extractions. The various extraction coefficients of the amine-borane complexes were determined. The newly prepared ligands were used in a variety of palladium-catalysed reactions as well as in the hydroformylation of 1-octene employing rhodium. The reactions were performed in both neat organic solvents as well as mixtures between water and DMF or toluene and the results were compared to the use of Tpp and Tppts. It was found that many of the new ligands afforded superior yields compared to those of Tpp and Tppts. In the last part of the study, various diphenylphosphinic amides were used as DoM-groups. Sec- and tert-BuLi were used together with a variety of electrophiles to facilitate ortho-substitution on either one or two rings on the amides. This was seen as a start of a new approach towards functionalised phosphine ligands. / Prof. D.B.G. Williams

Under the framework of dual-route theory of speech comprehension, two neurological routes are simultaneously active during speech decoding, the dorsal stream and the ventral stream. The dorsal stream is argued to be a sound processor whereas the ventral stream is a meaning processor, hence in cognitive terms, they are called the sound component and the meaning component respectively. Hypotheses concerning the processing speed and response accuracy of these two cognitive components were tested on compound words in Modern Mandarin Chinese. Four experiments were run contrasting, the sound-based task and the meaning-based task, corresponding to each of the two cognitive components. In Experiment 1 and 2, the Task effect was tested on one set of words in which the word-level and word-initial-syllable frequencies were controlled. In Experiment 3 and 4, the Task effect was tested on a different set of words in which semantic transparency was controlled. Multiple regression analyses integrating the data collected in Experiment 1-4 were conducted to test which language theory was preferred, the probability-based theory, the rule-based theory or the integrative theory. The probability-based theory suggests that speech comprehension of compound words relies only on the probability distribution of linguistic units. The rule-based theory suggests that speech comprehension of compound words relies only on phrase-structural rules. The integrative theory suggests that speech comprehension of compound words relies on both the probabilities of linguistic units and phrase-structural rules. It was suggested that the integrative theory explains the data best, but further data testing is needed to confirm this hypothesis. The results of the present study provide evidence for functional trade-off of the sound and meaning components, garden path effects during parsing opaque words and the possibility of the role of a mirror system in human speech comprehension.

This study is an investigation on the spatial span of Persian prepositions in colloquial speech, focusing on the locative use of prepositions. The results are compared with English prepositions as well. In order to show the functional span of various prepositions, the Typological Relations Picture Series known as TRPS or BowPed is used. This study demonstrates that the spatial span of Persian locative prepositions consists of twenty-eight prepositions, including three primary, seven compound and sixteen secondary prepositions. In some unusual relations in the BLCs (basic locative construction), the Persian prepositions reflect the opposite relation between the figure and ground. In addition, this study shows that there is greater variety of locative prepositions in Persian than English. Finally, the study concludes that like English, Persian allows the use of BLC over the entire range of the (eight) scenes; however, there is an overlap with the scope of BLC construction, which allows the use of resultative construction in Persian as well.

Thesis advisor: Jianmin Gao / Thesis advisor: Eranthie Weerapana / Cyclic peptides provide a privileged scaffold when optimizing interactions with various biological targets. Their rigidified structure decreases the entropic cost of binding by preorganizing residues in a fixed conformation, which may enhance binding affinity. These molecules occupy a larger chemical space than typical small molecule drugs and may provide good candidates for inhibiting protein-protein interactions or being able to interact with previously undruggable targets. Given the benefits of these structures we aim to develop a one-bead-one-compound peptide library for screening against relevant biological targets. Herein we describe several routes to achieving cyclic peptides through side chain interactions and head-to tail amide bond linkages. Additional considerations for the development of the on resin library such as linker strategies and sequencing methods will be discussed. / Thesis (MS) — Boston College, 2015. / Submitted to: Boston College.

Esta dissertação investiga o comportamento do acento nos compostos do idioma japonês. Os compostos do japonês falado em Tóquio apresentam apenas um acento, ou queda tonal H*L, por frase fonológica. Isso faz com que não se possa manter os acentos que estariam originalmente nas palavras simples. Apenas um acento sobrevive e seu local é de difícil determinação, porque, na maioria das vezes, não coincide com o local do acento anterior. Muitos linguistas já se debruçaram sobre esse tópico (McCAWLEY, 1965; SAITOU, 1997; KUBOZONO, 2001; TANAKA, 2001; LABRUNE, 2012) e com o auxílio dessas diferentes pesquisas, conseguimos estabelecer que diversos fatores influenciam no processo de acentuação dos compostos, especialmente aspectos morfológicos e fonológicos, como a fronteira de palavra e o pé fonológico. Assim, a acentuação do japonês não é determinada por cada membro do composto, mas pela distância em que a fronteira entre os membros está da margem direita da palavra. / This dissertation investigates the behavior of the accent of Japanese compounds. Compounds in Tokyo Japanese only have one accent, or pitch drop H*L, in a phonological phrase. Therefore, it cannot maintain the accent of the simple words which make it up. Only one accent survives and its location is hard to determine, because, most of the time, it does not coincide with the location of the previous accents. Many linguists have tackled this topic (McCAWLEY, 1965; SAITOU, 1997; KUBOZONO, 2001; TANAKA, 2001; LABRUNE, 2012) and with the help of these different analyses, we established that several factors influence the accentuation of a compound, especially morphological and phonological aspects, such as word boundary and phonological feet. Thus, the accentuation of Japanese compounds is not determined by each member of the compound in particular, but from the distance that the boundary between the compound \'s member is from the right margin of the word.
