Tibetan Market Participation in China

Since the Chinese government began implementing economic reforms in the late 1970s, China has experienced profound economic change and growth. Like other parts of China, Tibetan areas of China have also experienced wide-ranging economic change with growth even higher than the China-wide average in certain years. Though China s strategic policy of developing the West provided many opportunities for economic and business activities, Tibetans have proven poorly equipped to respond to and take advantage of these opportunities. This study is about people, about market participation and specifically about why Tibetans do not effectively participate in the market in the context of China s economic development process. Many political, social, cultural and environmental factors explain the difficulties met by Tibetan communities. However, this study focuses on three factors: the social and culture context, government policy and education. The Buddhistic nature of Tibetan communities, particularly the political and economic system in traditional Tibetan society, explains this, especially after implementation of new national economic policies. An inclusive economic development policy that promotes local people s participation in the market demands serious consideration of local conditions. Unfortunately, such considerations often ignore local Tibetan realities. The economic development policy in Tibetan areas in China is nearly always an attempt to replicate the inland model and open up markets, even though economic and sociopolitical conditions in Tibet are markedly unlike much of China. A consequence of these policies is increasing numbers of non-Tibetan migrants flowing into Tibetan areas with the ensuing marginalization of Tibetans in the marketplace. Poor quality education is another factor contributing to Tibetan inability to effectively participate in the market. Vocational and business education targeting Tibetans is of very low quality and reflective of government failing to consider local circumstances when implementing education policy. The relatively few Tibetans who do receive education are nearly always unable to compete with non-Tibetan migrants in commercial activity. Encouraging and promoting Tibetan participation in business development and access to quality education are crucial for a sustainable and prosperous society in the long term. Particularly, a localized development policy that considers local environmental conditions and production as well as local culture is crucial. Tibet s economic development should be based on local environmental and production conditions, while utilizing Tibetan culture for the benefit of creating a sustainable economy. Such a localized approach best promotes Tibetan market participation. Keywords: Tibet cultural policy education market participation

Imaging of knee injuries with special focus on tibial plateau fractures

Acute knee injury is a common event throughout life, and it is usually the result of a traffic accident, simple fall, or twisting injury. Over 90% of patients with acute knee injury undergo radiography. An overlooked fracture or delayed diagnosis can lead to poor patient outcome. The major aim of this thesis was retrospectively to study imaging of knee injury with a special focus on tibial plateau fractures in patients referred to a level-one trauma center. Multi-detector computed tomography (MDCT) findings of acute knee trauma were studied and compared to radiography, as well as whether non-contrast MDCT can detect cruciate ligaments with reasonable accuracy. The prevalence, type, and location of meniscal injuries in magnetic resonance imaging (MRI) were evaluated, particularly in order to assess the prevalence of unstable meniscal tears in acute knee trauma with tibial plateau fractures. The possibility to analyze with conventional MRI the signal appearance of menisci repaired with bioabsorbable arrows was also studied. The postoperative use of MDCT was studied in surgically treated tibial plateau fractures: to establish the frequency and indications of MDCT and to assess the common findings and their clinical impact in a level-one trauma hospital. This thesis focused on MDCT and MRI of knee injuries, and radiographs were analyzed when applica-ble. Radiography constitutes the basis for imaging acute knee injury, but MDCT can yield information beyond the capabilities of radiography. Especially in severely injured patients , sufficient radiographs are often difficult to obtain, and in those patients, radiography is unreliable to rule out fractures. MDCT detected intact cruciate ligaments with good specificity, accuracy, and negative predictive value, but the assessment of torn ligaments was unreliable. A total of 36% (14/39) patients with tibial plateau fracture had an unstable meniscal tear in MRI. When a meniscal tear is properly detected preoperatively, treatment can be combined with primary fracture fixation, thus avoiding another operation. The number of meniscal contusions was high. Awareness of the imaging features of this meniscal abnormality can help radiologists increase specificity by avoiding false-positive findings in meniscal tears. Postoperative menisci treated with bioabsorbable arrows showed no difference, among different signal intensities in MRI, among menisci between patients with operated or intact ACL. The highest incidence of menisci with an increased signal intensity extending to the meniscal surface was in patients whose surgery was within the previous 18 months. The results may indicate that a rather long time is necessary for menisci to heal completely after arrow repair. Whether the menisci with an increased signal intensity extending to the meniscal surface represent improper healing or re-tear, or whether this is just the earlier healing feature in the natural process remains unclear, and further prospective studies are needed to clarify this. Postoperative use of MDCT in tibial plateau fractures was rather infrequent even in this large trauma center, but when performed, it revealed clinically significant information, thus benefitting patients in regard to treatment.

Kinetic theory for the density plateau in the granular flow down an inclined plane

The striking lack of observable variation of the volume fraction with height in the center of a granular flow down an inclined plane is analysed using constitutive relations obtained from kinetic theory. It is shown that the rate of conduction in the granular energy balance equation is O(delta(2)) smaller than the rate of production of energy due to mean shear and the rate of dissipation due to inelastic collisions, where the small parameter delta = (d/(1 - e(n))H-1/2), d is the particle diameter, en is the normal coefficient of restitution and H is the thickness of the flowing layer. This implies that the volume fraction is a constant in the leading approximation in an asymptotic analysis in small delta. Numerical estimates of both the parameter delta and its pre-factor are obtained to show that the lack of observable variation of the volume fraction with height can be explained by constitutive relations obtained from kinetic theory.

Origin of the plateau in the low-temperature thermal conductivity of silica

Thermal conductivities of glasses at low temperatures show strikingly similar behavior irrespective of their chemical composition. While for T<1 K the thermal conductivity can be understood in the phenomenological tunneling model; the ‘‘universal plateau’’ in the temperature interval 15>T>2 K is totally unexplained. While Rayleigh scattering of phonons by structural disorder should be the natural cause for limiting the mean free path of phonons in this temperature range, it has been concluded before that in glasses a strong enough source of such scattering does not exist. In this study we show by a proper structural analysis in at least one material (namely, silica) that a strong enough source of Rayleigh scattering of phonons in glasses does exist so that the ‘‘universal plateau’’ can be explained without invoking any new mechanism. This may be for the first time that the low-temperature property of a structural glass has been correlated to its structure.

Vertical and seasonal distribution of phytoplankton in the Shen Reservoir Plateau State, Nigeria

The phytoplankton distribution of the Shen Reservoir, Bukuru in the Jos Plateau, Nigeria was monitored at 6 depths. Higher floral abundance occurred within the upper 00-03 meters with highest values at the first 1 meter. Bacillariophyceae and Dinophyceae recorded higher values in March-April with lower values in July and January respectively. Phytoplankton were most abundant in the rainy season. Secchi disc transparency was lowest in the peak of the rainy season (July) due to higher levels of suspended matter resulting from the increased run-off from surrounding farmlands of allochthonous materials as well as higher levels of phytoplankton population arising from the former factor. The low water temperature of December/January 15 degree C plus or minus 2 degree C might have depressed growth among the major groups of plankters but enhanced rapid multiplication of the Chlorophyta, Trachelomonas which showed a bloom at this season

Investment prospects of fish farming in the Jos-Plateau, Nigeria

The investment prospects of fish farming in the Jos-Plateau, Nigeria, strategically located in about the centre of the country are discussed with special reference to its numerous abandoned mine lakes and the tripartite role of government, universities and individuals. In the Jos-Plateau, about 17.0 km super(2) is covered by these disused mine lakes, making up about 20-30% of the area covered. In such enterprise, problems commonly encountered, like population growth and government planning policies, fish demand and supply, manpower, feed and seed availability, preservation, processing and marketing are discussed. Inspite of these, prospects still abound with regards to land-use of these numerous disused mine lakes and feed availability based on the principles of using both industrial and farm by-products for fish culture, processing and marketing. These potentials, if properly harnessed, will help to supplement the protein insufficiency in the diet of the populace. In this regard, proposals on the economics of production and sales, strategies for achieving these development goals, cost-benefit analysis and their implications in further development of fish culture are discussed
