Using rotated principal component analysis, 200mb wind data from the First GARP Global Experiment are analyzed in the East Asia winter monsoon region. It is found that there exist slowly eastward-moving disturbances with a wind-speed maximum embedded in the jet stream (jet streak). The implied vertical circulation that is transverse to the jet streak is thermally direct in the entrance region of jet streak and thermally indirect in the exit region. The Lagrangian momentum equation for transient part of the flow indicates that the magnitude of westerly acceleration of an air parcel moving through the jet streak is related to the Coriolis acceleration of the transient ageostrophic flow, the advection of mean momentum by transient flow and momentum conversion between mean and transient flow due to transient eddies. Estimates of terms in this equation in the entrance region of jet streak suggest that the increase of westerly momentum due to the Coriolis acceleration of the ageostrophic flow is mostly balanced by the decrease due to the mean easterly momentum advection by the transient jet-streak flow. Thus, the confluence theory of Namias and Clapp (1949) appears to be valid for the slowly moving jet streaks in the East Asia jet stream. / Graduation date: 1989

This thesis analyzes the ways in which the Japanese state uses the disabled body and disability athletics as a tool of governance and how that affects the incorporation of disabled people into Japanese society. Throughout Japan's history the disability identity has been a subject of negotiation between social actors including the government, general public, those with disabilities, and powerful international collectives. After World War II, disabled former soldiers were celebrated for their national sacrifice while other disabled bodies were displaced. In later decades, disability athletics became a space where the symbol of the ideal disabled body has been promoted for public consumption. On the stage of athletics, various actors have shaped and influenced each other by advocating different visions of the disabled body in Japanese society. Disabled athletes negotiate depictions of disability as idealized (the 'super crip') or stigmatized (the 'pitiable disabled person'), and these depictions in turn create public expectations for what the disabled body should be but at times glosses over the struggles of many disabled people. The purpose of this thesis is to consider how notions of the disabled body are used to negotiate nationalism, modern ideas of care and social responsibility, and expectations to become a body of inspiration for the disabled community and the general public. The core question is: What are the implications of the disabled body being used as a tool on the stage of disability athletics for governance in modern day Japan? The thesis will provide a basis for deeper understanding about the relevance of disability athletics as both a form of governance and a site of identity formation for the disabled.

The current study examines cranial variation of contemporary East Asians with an aim to comprehensively describe and define the morphology of people in this region. In doing so, a better understanding of the causes of variation within East Asia and compared to other geographic populations is sought. The study encompasses a broad range of samples from Northeast Asia to island Southeast Asia. Traditional linear and angular data and analytical methods (e.g Box and Whisker, Principal Components Analysis) were used to assess cranial variation. Thus the results may be compared to published studies using traditional craniometric approaches. Innovative geometric morphometric data collection and analysis techniques are also used here for the first time. Results show East Asians are distinguishable from non-Asians on the basis of their tall, round, vault, shorter cranial length, tall faces that are flattened in the upper and mid-facial regions, short malars (anteroposterior length), narrow interorbital breadth and orthognathism. A north-south East Asian cline was also detected, with the northern samples exhibiting tall, orthognathic faces, and a long low vault. This long, low vault shape is in contradiction to the purported shape of cold-climate adapted populations. Southern East Asians possess a tall, rounded vault and a short, projecting (prognathic) face. Island Southeast Asians inhabiting the Andaman and Nicobar Islands exhibit a 'mixed' morphology, possessing the southern East Asian facial form, but the long, low vault seen in northern East Asian samples. The long, low vault also characterises non-Asian samples from Australia, Africa and Melanesia. Shape differences were significantly associated with latitude, explaining most of the variation. The identification of ancestral East Asian features in recent samples suggests phylogenetics may also be contributing to variation in part. The study concludes that there is clear evidence for geographical variation among modern East Asians, some if it being continuous (clinal) and some discontinuous. Importantly, much of the variation reflects adaptation to climate, with a phylogenetic component also recognised. The study contributes to our understanding of human evolution in a region that today constitutes around half of the world?s population.

The work presented in this thesis document reflects the results of a study carried out to better quantify the magnitude and fate of the anthropogenic air pollutants emitted from East Asia. Simulations of anthropogenic sulfur compounds by a regional on-line coupled chemistry-climate model suggest that large portions of East Asia have high SOx concentrations, and most subregions within East Asia are net exporters of SOx (SO2+SO4) (i.e. the anthropogenic S emissions from the region are greater than the deposition to the region). Among them, China is responsible for ~ 85% of the total emissions, and ~ 50 % of its total emitted SOx is exported to locations outside its borders. During the later winter to early spring when the continental outflow conditions predominate, about 20% of the total emitted SOx within the investigated area has been exported to North Pacific Ocean based on our model simulations. Those exported anthropogenic SOx from East Asia (mainly in the form of sulfate) is likely large enough to perturb the sulfate aerosol concentration over the North Pacific Ocean. Our investigation by integrating numerical simulations through a regional off-line full chemistry transport model, which is driven by the meteorological conditions calculated by a regional climate model, with field measurements of both gaseous and particulate species at a rural site adjacent to the largest industrialized area in China suggests that CO emissions from China, especially eastern China are likely underestimated by ~ 50 % in the current East Asia anthropogenic emission inventories. In addition, a 60-90 % underestimation of particulate carbonaceous emission in the inventories is suggested. Further statistical diagnoses, together with the back-trajectory analysis show that the missing CO sources are likely associated with SO2 sources that are already accounted for in the current inventories. This in turn suggests the emission factors of coal-combustors used in the current inventories are likely underestimated.
