The Evualation of the Position of Economic Zone of the West Coast of the Taiwan Strait from the Perspective of Taiwan¡¦s Global Economic & Trade Strategy

Chen, Wei-cheng 05 September 2011 (has links)
In this paper I start from the exploration of the change of industrial structure during the economic development in Taiwan after World War II. Through the document analysis, I find out the reasons why the manufacture and service industries move outside to mainland China and other areas around the world are because of the extension of market and the cut down of cost. Since China is the most important trade partner of Taiwan, I focus the study on the economic zones in China, especially the economic zone of West Coast of Taiwan Strait (West Coast economic zone). The argument of this paper is that Taiwan should take advantage of the favor policy of economic zones in China and build the supply chain in the certain economic zones with local comparative advantage industries. And the evaluation of Taiwan¡¦s economic strategy depends on which economic zone in China can offer the supply chain advantage industries with the need of Taiwan¡¦s industries. After the comparison of the current trends of the investment of Taiwanese businessmen in West Coast economic zone and other economic zones in mainland China, I find out West Coast economic zone is not Taiwanese businessmen¡¦s best choice to invest. To attract more investments from Taiwan, the authority of West Coast economic zone should alter its favor policy according to co-opettion strategy and to meet the need of Taiwan industries. In conclusion, I suggest the authorities on both side of Taiwan strait should offer the need of local comparative advantage industries according to the supply chain theory, by this way, we can get a win-win result for the both side of Taiwan Strait.

Does coastal western hemlock respond to fertilization?

Klinka, Karel January 2001 (has links)
Response to fertilization is a function of the degree to which nutrients are limiting growth, the capacity of individual trees to respond to nutrient inputs, the degree to which other factors limit growth, and the possible extrinsic effects of treatment (e.g., root mortality due to fertilizer-induced soil pH effects). Recognition and examination of these factors is essential if response to fertilization is to be predictable. Over the past 25 years numerous western hemlock fertilizer trials have shown responses ranging from negative to positive with no clear trends. Theories for this erratic response include: (a) different nutritional requirements during different stages of stand development; (b) high native N availability or low supplies of other nutrients (P and S, in particular); (c) differential adverse effects of N fertilizers on surface roots, mycorrhizal populations and P nutrition; (d) a requirement for slow release N; and (e) induced water stress. The objective of this study was to develop site-specific guidelines for western hemlock fertilization decision-making for industrial use. This study reports on the first and third growing-season response to two different fertilizer treatments, and identification of possible relationships between fertilizer response and site and stand conditions.

Estimated decrease in productivity for pacific silver fir as elevation increases

Klinka, Karel January 1998 (has links)
When making decisions on which areas to harvest in a sustained yield, even-flow manner in mountainous areas such those in coastal British Columbia, it is important to know how timber productivity changes with elevation. This information allows foresters to decide at what elevation to start increasing the rotation age and to decide at what elevation sustainable harvesting becomes infeasible due to low productivity. Since Pacific silver fir (Abies amabilis Dougl. ex Forbes) has an elevation range that extends from sea level nearly to the tree line (0 m to approximately 1,650 m; from the Coastal Western Hemlock zone, through the Mountain Hemlock zone; to the lower limits of the Alpine Tundra zone), productivity-elevation relationships are especially important. To acquire quantitative measures of productivity decrease with increasing elevation a regression equation relating site index (the height of the dominant trees at a base age of breast height age of 50 years) to elevation in southern coastal BC was developed. In turn, we used this regression as an input into the height driven yield model named the Variable Density Yield Prediction model (VDYP). The use of the VDYP model allows the site index values to be translated into actual productivity measures (e.g., volume per hectare, mean annual increment at culmination age).

Comparison of soil acidification and intensity of podzolization beneath decaying wood versus non-woody forest floors in coastal BC

Klinka, Karel, Kayahara, Gordon J., Chourmouzis, Christine January 2001 (has links)
Forest managers concerned with maintaining soil productivity must consider the impacts of forestry practices upon the features of a site. One critical feature is the amount and type of organic matter on a site, which may affect soil development. This study addresses the question of whether CWD accumulations increase the intensity of podzolization, thus reducing the long-term productivity of a site.

West Coast Apocalyptic: A Site-Specific Approach to Genre

MELSOM, RYAN J 26 January 2011 (has links)
Key studies of apocalypse in previous years have consciously and unconsciously understood the genre in terms of its paradigmatic consistency across examples. This emphasis points out valuable similarities among a wide range of texts, but also diminishes the significance of a text’s locally and historically rooted ways of depicting experience. This study reflects an effort to rebalance the meaning of apocalypse by looking at a specific locale – the North American West Coast. I examine popular, critical, and literary representations of the West Coast to trace out the unique ways that they configure regional identities. Ultimately, I make the case for site-specific criticism, which values provisional, locally rooted terminologies and tropes for analyzing cultural problems. / Thesis (Ph.D, English) -- Queen's University, 2011-01-26 14:00:17.35

A GIS approach to landslide hazard management for the West Coast region, New Zealand.

England, Kevin January 2011 (has links)
Landslides, in their various forms, are a common hazard in mountainous terrain, especially in seismically active areas and regions of high rainfall. The West Coast region of New Zealand is dissected by many active faults, experiences frequent earthquakes and in many locations annual rainfall exceeds ten meters. Consequently, landslides are widespread in the region and since European settlement began, have been responsible for 27 deaths, along with frequent damages to road and rail infrastructure, settlements and agricultural land. This study identifies areas that are susceptible to rainfall triggered landslides in the West Coast region. To achieve this, a landslide susceptibility map was produced using bivariate statistics and the analytical hierarchy process. It has an accuracy that predicts 80% of all the landslides in the top 40% of the susceptibility scores on the map. As part of this process, 3221 rainfall triggered landslides and 522 earthquake (or other trigger) triggered landslides have been mapped and digitised into a Geographic Information System. In parallel with this, a descriptive historical catalogue of 1987 landslides has been compiled from the available sources. These new tools provide decision-makers with an enhanced means of managing landslide hazards in the West Coast region. In order to avoid misinterpretation the study has been carried out in compliance with the “Guidelines for landslide susceptibility, hazard and risk zoning for land use planning”, which was published in 2008 by the Joint Technical Committee on Landslides and Engineered Slopes. The tools developed in this thesis represent a fundamental step in land-use planning and set-up of landslide hazard management in the West Coast region.

The Gumboot Navy: Securing or Sundering British Columbia

Kier, Gregory David 26 August 2014 (has links)
In 1938 the Canadian government approved a plan to train fishermen as naval reservists in British Columbia. The fishermen were recruited as whole crews and trained to shoot accurately, form fours, navigate, signal properly and drop depth charges – all aboard their own converted fishing vessels. On paper, and to the general public, the specialized reserve known as the Fishermen’s Reserve or “Gumboot Navy”, was a patriotic group of fishermen doing their bit and better preparing for emergencies. However, in reality, the Canadian government instituted the Fishermen’s Reserve in 1938 for a very specific reason – to round up and remove Japanese Canadians and their boats from the coast prior to the outbreak of war between Canada and Japan. This thesis explores various aspects of the Fishermen’s Reserve from 1938 to 1941 in order to better understand the Canadian Government’s wartime policies. As there are almost no secondary sources on the subject, this paper uses extensive primary sources to uncover and analyze the Royal Canadian Navy’s recruitment policy, unconventional regulations and racist underpinnings in instituting the Fishermen’s Reserve. / Graduate / 0334 / 0750 / 0740 / gregory.kier@gmail.com
