Ambisyllabicity versus Foot in English Segmental Phonology

There have been controversies in English Phonology that center around the raison d'é e of ambisyllabicity in accounting for English phonological processes. The goal of this thesis is to argue that ambisyllabicity provides a more rigorous account of English phonological phenomena. Specifically, it is shown in this thesis that ambisyllabicity-based approach explains flapping glottalisation, I-velatisation, and palatalisation more accurately than foot-based approach. This thesis claims that the existence of ambisyllabicity is well justified while foot-boundaries are not well defined in foot-based approach. In sum, this thesis reveals that foot-based approach cannot substitute ambisyIIabicity-based approach. The notion of ambisyllabicity is necessary because ambisyllabicity-based approach has the explanatory adequacy. This thesis illustrates how ambisyllabicity is incorporated into Optimality Theory.Supported by the Grant for the Reform of University Education under the BK21 Project of SNU

Materialized Wishes: Long Banner Paintings from the Mogao Caves of Dunhuang

This paper explores the religious function and meaning of long banner paintings from Cave 17 of the Mogao Caves in Dunhuang, in conjunction with material culture in Northwestern China in the ninth and tenth centuries CE. The so-called forty-nine-chi banners have peculiar traits such as extremely long lengths, an optional triangular headpiece, and a paired or single strip of textile on which a series of standing bodhisattvas are painted. The author focuses on the large number of textiles used for such banners and questions how the extraordinary length and material used contributed to fulfilling the donor’s wishes. By examining both the banners’ physical characteristics, such as the type of textiles, pigments, and configurations, and the theological background based on the Buddhist and Daoist scriptures about longevity, repentance, and healing, the author suggests that the long banners are a materialized form of longevity and prosperity by physically lengthening the banner with multiple bolts of silk. This paper further argues that depicting multiple bodhisattvas in a pictorial form on a long strip of textile was regarded equally as a powerful means for obtaining good health, prolonging life, eliminating sins, and thus being reborn in the Pure Land

The Superiority Violation for Multiple Wh-Interrogatives in the Optimality Theory Framework on the Synthetic Constraints

In English multiple wh-interrogatives are particularly blocked as they violates the superiority condition (e.g., *What has seen who?) and remain an active issue of debate. There have been various analysis on the superiority violation (hereafter, SUV). For instance, Kuno and Robinson (1972) initially identified multiple wh-interrogatives. They used the syntactic approach on analysing SUV of wh-interrogatives. The higher wh- should c-command the lower wh-. (e.g., *What will who buy?) Next, the triple wh-, which first appeared on Chomsky (1973), results a problem according to the syntactic approach (e.g., John wonders what who say when.). Additionally, Pesetsky (1984) develops the D(discourse)-linking and the non-D-linking as the semantic approach to illustrate triple wh-interrogatives (e.g., What did which woman buy?). Futhermore, Dayal (2005) studied multiple wh-interrogatives as the phonological approach (e.g., Has who seem what?). Despite a lot of discussion have been done, previous papers are not sufficient for describing SUV. The upshot of this study is to investigate how well multiple wh-interrogatives as one of syntactic phenomenon can be controlled by an integrative alternative, the synthetic approach which utilize syntactic (e.g., Q-free, *Q-cross), semantic (e.g, *New), and phonological constraints (e.g., Rhythm) in OT framework and to refer rhythm patterns

Evaluation of Air Temperature, Photoperiod and Light Intensity Conditions to Produce Cucumber Scions and Rootstocks in a Plant Factory with Artificial Lighting

Air temperature and light conditions are important factors not only to produce high-quality seedlings but also to promote energy efficiency in a plant factory with artificial lighting. In this study, we conducted two experiments in order to investigate the favorable conditions of air temperature, light intensity and photoperiod for the production of cucumber scions and rootstocks in a plant factory with artificial lighting. Cucumber scions and rootstocks were cultivated in two combined treatments: the combination of three different levels of difference between the day and night temperature (DIF), 25/20, 26/18 and 27/16 °C and five different light intensity conditions of photosynthetic photon flux, 50, 100, 150, 200 and 250 μmol·m−2·s−1 was set for the first experiment, and the combination of three different photoperiod conditions, 12, 16 and 20 h·d−1 and five different light intensity conditions, 50, 100, 150, 200 and 250 μmol·m−2·s−1 was set for the second experiment. In the air temperature and light intensity treatments, the hypocotyl elongation of cucumber scions and rootstocks was affected more largely by light intensity than DIF. The highest DIF treatment (27/16 °C) affected negatively on the accumulation of dry mass. On the contrary, the smallest DIF treatment (25/20 °C) was favorable for seedling growth due to lesser stress by rapid change of air temperature between photo- and dark-period. In the photoperiod and light intensity treatments, an increased DLI (daily light integral) promoted the growth of scions and rootstocks. Under the same DLI condition, the growth of scions and rootstocks increased with increasing photoperiod and decreasing light intensity. In both of experiments, while the dry weight increased with increasing the light intensity, the light use efficiencies were reduced by increasing the light intensity. Considering the growth and quality of seedlings and energy efficiency, the optimal environment conditions were represented by 25/20 °C of air temperature, 150 μmol·m−2·s−1 of light intensity and 16 h·d−1 of photoperiod

A role for subducting clays in the water transportation into the Earth’s lower mantle

Subducting sedimentary layer typically contains water and hydrated clay minerals. The stability of clay minerals under such hydrous subduction environment would therefore constraint the lithology and physical properties of the subducting slab interface. Here we show that pyrophyllite (Al2Si4O10(OH)2), one of the representative clay minerals in the alumina-silica-water (Al2O3-SiO2-H2O, ASH) system, breakdowns to contain further hydrated minerals, gibbsite (Al(OH)3) and diaspore (AlO(OH)), when subducts along a water-saturated cold subduction geotherm. Such a hydration breakdown occurs at a depth of ~135 km to uptake water by ~1.8 wt%. Subsequently, dehydration breakdown occurs at ~185 km depth to release back the same amount of water, after which the net crystalline water content is preserved down to ~660 km depth, delivering a net amount of ~5.0 wt% H2O in a phase assemblage containing δ-AlOOH and phase Egg (AlSiO3(OH)). Our results thus demonstrate the importance of subducting clays to account the delivery of ~22% of water down to the lower mantle

The stability of subducted glaucophane with the Earth’s secular cooling

The blueschist to eclogite transition is one of the major geochemical–metamorphic processes typifying the subduction zone, which releases fluids triggering earthquakes and arc volcanism. Although glaucophane is an index hydrous mineral for the blueschist facies, its stability at mantle depths in diverse subduction regimes of contemporary and early Earth has not been experimentally determined. Here, we show that the maximum depth of glaucophane stability increases with decreasing thermal gradients of the subduction system. Along cold subduction geotherm, glaucophane remains stable down ca. 240 km depth, whereas it dehydrates and breaks down at as shallow as ca. 40 km depth under warm subduction geotherm or the Proterozoic tectonic setting. Our results imply that secular cooling of the Earth has extended the stability of glaucophane and consequently enabled the transportation of water into deeper interior of the Earth, suppressing arc magmatism, volcanism, and seismic activities along subduction zones

Graphite resistive heated diamond anvil cell for simultaneous high-pressure and high-temperature diffraction experiments

International audienceHigh-pressure and high-temperature experiments using a resistively heated diamond anvil cell have the advantage of heating samples homogeneously with precise temperature control. Here, we present the design and performance of a graphite resistive heated diamond anvil cell (GRHDAC) setup for powder and single-crystal x-ray diffraction experiments developed at the Extreme Conditions Beamline (P02.2) at PETRA III, Hamburg, Germany. In the GRHDAC, temperatures up to 2000 K can be generated at high pressures by placing it in a water-cooled vacuum chamber. Temperature estimates from thermocouple measurements are within +/−35 K at the sample position up to 800 K and within +90 K between 800 and 1400 K when using a standard seat combination of cBN and WC. Isothermal compression at high temperatures can be achieved by employing a remote membrane control system. The advantage of the GRHDAC is demonstrated through the study of geophysical processes in the Earth’s crust and upper mantle region
