Sources and Controls of Sulphur Export in Precambrian Shield Catchments in South-central OntarioEimers, M. Catherine January 2002 (has links)
A series of studies was undertaken at Plastic Lake-1 (PC1) to determine the sources and controls on S cycling in small headwater catchments on the Precambrian Shield in south-central Ontario. Two observations were made about the S cycle in this region: (1) all streams exhibit highly coherent temporal patterns in SO4 concentrations and export, and (2) most catchments exported more SO4 in stream water than is received in bulk deposition during the past 2 decades. Synchronous temporal patterns in annual SO4 concentrations in both upland and wetland-draining streams were related to changes in climate, specifically those factors that determine catchment dryness. The number of days with no stream flow or stream flow below a critical threshold was a good predictor of the average stream SO4 concentration in a particular year. Sulphate chemistry in the PC1 outflow is highly dependent on processes occurring in a conifer <i>Sphagnum</i> swamp located immediately upstream of the chemical sampling station. Hydrologic inputs to the swamp during the summer determine whether S is retained or released from peat on an annual basis. Drying and re-wetting of <i>Sphagnum</i>-derived peat caused a substantial increase in soluble SO4 in laboratory experiments, which was slightly enhanced at higher temperature, but alternating moisture conditions had no immediate effect on <i>Sphagnum</i>. Despite large inter-annual changes in SO4 release, over the long-term (<i>i. e. </i> 20-years) SO4 inputs and exports from the swamp are in approximate balance. In contrast, the upland portion of PC1 (<i>i. e. </i> PC1-08) consistently exports more SO4 than is input in bulk deposition in every year of record. Even when inputs are increased to account for potential underestimates in dry deposition or weathering, the majority of catchments in this region exhibit net export in many years. Two internal sources are suggested to account for negative budgets: desorption and mineralization. Adsorption/desorption reactions respond directly to changes in SO4 input concentration, and lysimeter data indicate the importance of these processes for buffering short-term changes in SO4 concentration in LFH percolate. Desorption may be the primary direct response of upland soil to decreasing SO4 inputs in deposition and may substantially extend the period of net SO4 export in catchments that have large adsorbed SO4 pools such as PC1. However, the adsorbed pool may be sustained by continuous net release from mineralization, and should also be considered in budget calculations. Mineralization was shown to be responsive to drying and re-wetting events and temperature, although results varied among different materials. Sulphate release from mineral soil did not appear to be influenced by changing moisture, temperature or deposition chemistry in laboratory experiments, although adsorption/desorption reactions may have largely masked small changes in SO4 release <i>via</i> mineralization. The magnitude of organic S storage in mineral soil indicates that this pool could be an important source of export over the long-term. While it is unknown why (or if) mineralization is a net source of SO4 to drainage streams, changes in climate and/or deposition could potentially influence SO4 release from organic compounds. Soil moisture and temperature are important controls on microbial processes in soil, and changes in climate that bring about changes in soil moisture or temperature conditions could affect decomposition and mineralization processes. Similarly, historically high inputs of S and N in deposition may have brought about slow shifts in litter quality (<i>i. e. </i> decreased C:N, C:S) which could also potentially influence decomposition and mineralization rates. In order to predict the future response of surface water chemistry to changes in SO4 (and N) deposition, it is important to consider not only the magnitude of S pools in soil, but also the potential for SO4 cycling between pools. Likewise, models that predict changes in stream SO4 by adsorption isotherm data alone will underestimate the importance of desorption unless the potential for continual replenishment of the adsorbed pool through the relatively slower process of mineralization is also considered. In general, predictions of recovery from S deposition can only be made from a complete understanding of S pools, transformations, and the effects of climate, which are superimposed upon the long-term trend in deposition.

GDP Elasticities of Export Demand : An analysis of Sweden’s export flows to Germany and other trading partnersNilsson, Camilla, Bönninger, Mareike January 2012 (has links)
Exports are an important source of income for Sweden. They are influenced by macroeconomic factors such as GDP. This paper examines the elasticity of Swedish export to changes in the GDP of Sweden’s 25 most important export partners. The sensitivity to changes in GDP, the elasticity, can be different for different goods. Therefore, we examine export elasticities for five different commodity groups, which include durable as well as non-durable goods. Moreover, special focus is put on the trade relationship between Sweden and Germany in order to see if their long common trade history has any impact on the elasticity of Swedish exports to Germany. The analysis is based on an export demand function that links exports to GDP and geographical distance. We include dummy variables in our regression model to control for EU-membership and common borders. For Swedish exports to Germany, we find that exports of food and live animals are least elastic, whereas exports of machinery and transport equipment are most elastic. This is coherent with previous empirical findings about demand elasticities of non-durable and durable goods. We find that exports in two out of five commodity groups are unit elastic. This means that when German GDP increases by one percent, Sweden’s export to Germany in these commodity groups also grows by approximately one percent. Thus, Sweden is not able to capture additional profit through over proportional increases in exports to Germany. For Swedish exports to its 25 most important trading partners, on average, we find that exports of manufactured goods as well as machinery and transport equipment are the least elastic exports. This gives them the lowest growth potential.

Enhancing the distribution of Swedish tourism services on international markets : Possible export-ready criteria requisitioned by European tour operatorsGahleitner, Hans-Peter January 2011 (has links)
This paper identifies subjects which are relevant for Swedish suppliers of tourism services beforeapproaching foreign markets. Most suppliers are micro, small or medium sized companies anduse intermediaries, such as tour operators, for internationalization. The research considers theopinion of British and German tour operators, which require some criteria beforehand in orderto simplify both the initialization and the development of cooperation. Destination marketingorganizations (DMOs) are hereby the go-betweens since they not only represent small-scalesuppliers on international markets, but also initiate first encounters between suppliers and touroperators. Suppliers need to provide DMOs with accurate information in order to ensure thebest possible representation. After initializing collaboration, business relationships are sought todevelop in order to facilitate long-term cooperation. Proper preparation forms therefore the basefor strengthening the competitiveness of Swedish tourism prior approaching internationalmarkets. The enhancement of distributing Swedish tourism services on foreign markets appearedto be a profitable way to enable further growth, which is strongly limited on the domestic market.Increasing the export share therefore secures and further facilitates tourism’s valuablecontributions to the Swedish economy.

Characterization of the Association of mRNA Export Factor Yra1 with the C-terminal Domain of RNA Polymerase II in vivo and in vitroMacKellar, April January 2011 (has links)
<p>The unique C-terminal domain (CTD) of RNA polymerase II (RNAPII), composed of tandem heptad repeats of the consensus sequence YSPTSPS, is subject to differential phosphorylation throughout the transcription cycle. Several RNA processing factors have been shown to bind the appropriately phosphorylated CTD, and this facilitates their localization to nascent pre-mRNA during transcription. In <italic>Saccharomyces cerevisiae</italic>, the mRNA export protein Yra1 (ALY/REF in metazoa) has been shown to cotranscriptionally associate with mRNA and is thought to deliver it to the nuclear pore complex for export to the cytoplasm. Based on a previous proteomics screen, I hypothesized that Yra1 is a <italic>bona fide</italic> phosphoCTD associated protein (PCAP) and that this interaction is responsible for the pattern of Yra1 cotranscriptional association observed <italic>in vivo</italic>. Using <italic>in vitro</italic> binding assays, I show that Yra1 directly binds the hyperphosphorylated form of the CTD characteristic of elongating RNAPII. Using truncations of Yra1, I determined that its phosphoCTD-interacting domain (PCID) resides in the segment comprising amino acids 18-184, which, interestingly, also contains the RNA Recognition Motif (RRM) (residues 77-184). Using UV crosslinking, I found that the RRM alone can bind RNA, although a larger protein segment, extending to the C-terminus (aa 77-226), displays stronger RNA binding activity. Even though the RRM is implicated in both RNA and CTD binding, certain RRM point mutations separate these two functions: thus, mutations that produce defects in RNA binding do not affect CTD binding. Both functions are important <italic>in vivo</italic>, in that RNA binding-defective or CTD binding-defective versions of Yra1 engender growth and mRNA export defects. I also report the construction and characterization of a useful new temperature sensitive <italic>YRA1</italic> allele (<italic>R107AF126A</italic>). Finally, using chromatin immunoprecipitation, I demonstrate that removing the N-terminal 76 amino acids of Yra1 (all of the PCID up to the RRM) results in a 10-fold decrease in Yra1 recruitment to genes during elongation. These results indicate that the PCTD is likely involved directly in cotranscriptional recruitment of Yra1 to active genes.</p> / Dissertation

The Competition Analysis of Aquatic Products in the International Markets between Taiwan and ChinaHsieh, Chung-hsien 21 July 2011 (has links)
In 1970,China carry out economic reform policy, development export-oriented agriculture, because of having the advantage of low-cost labor and land resource, loosen economic control and attract foreign capital investment gradually. In 1980, Taiwan entrepreneur start to investment agriculture related industry in China, and to bring in technology improved seed. but reviews the home, because environmental consciousness, the factory moves gradually toward the Southeast Asian country and China.Comparatively speaking, our country competitive power has the drop tendency. Separately, Taiwan and China joined one after another in WTO about in 2002, affect product wish of our country farmer because possible the low price to rob the market. We discuss bilateral in international market sales situation, the export market comparison from the Taiwan ten main aquatic products, the result discovered that the Taiwan most aquatic products all substitute by China, the government must propose in accordance to the plan and achieves the industry to continue forever to manage.

Identification of the NLS and NES of DaxxYang, Yi-Chin 30 August 2004 (has links)
SUMO is a small ubiquitin-like modifier. The fluorescent fused SUMO (active for sumoylation) localized in the nucleus, while C-terminal truncated SUMO (inactive for sumoylation) diffused in the cytoplasm. Daxx is a SUMO target protein, locates predominantly in the nucleus. It has been identified as a component of the PODs. During extracellular stimulation, Daxx could be recruited to the cytoplasm with the existence of Ask1. Therefore, it is a shuttle protein. Daxx should contain nuclear localization signal (NLS) and nuclear export signal (NES) motifs. To identify the NES and NLS motifs on Daxx, Daxx were truncated into four segments. Several amino acids on the predicted NES and NLS motifs were mutated. Our results showed that the truncated Daxx fragments D1 (containing NES) and D4 (containing NLS2) could be translocated into nucleus independently. However, either NES or NLS2 mutants disrupted their translocation into nucleus. It indicated that both NES and NLS2 motif of Daxx were involved in the nuclear transport. Nevertheless the co-transfection of SUMOs and Daxx showed that the interactions between SUMO active form and Daxx mutants and between inactive SUMO and Daxx wild type rescued the nuclear transport function of Daxx mutants and inactive SUMO. Therefore, SUMO may play a role in the nuclear transport of Daxx by either sumoylation or interaction with Daxx in cytoplasm, and Daxx may recruit inactive SUMOs into nucleus by interaction.

The Study of America's Export Control toward ChinaWu, Tsung-hsien 02 July 2007 (has links)
Analysis of the America¡¦s Export Controls toward China is based on theoretical framework that will explore the process of decision-making, transformation, strategy, and challenge of the America¡¦s export controls toward China. Since the Cold War, America adjusts her export controls towards China with two theoretical approaches: Neo-realism focuses on national security and Neo-liberalism focuses on economical benefits, while its export control towards China has been dictated by the transformation of her international and domestic political economic environments. Following the Cold War, instead of abolishing it¡¦s unilateral and multilateral export controls, and motivated by the 911 incident and its anti-terrorism policy, America further strengthens its export controls and appropriately adapts the rising China to become one of its major export control countries so to reach global governance. The flexible and waiting-for-opportunity characters of America¡¦s export controls bring about some vital implications to Taiwan¡¦s policy-making in issue-areas including cross-strait relations, defense policy, and foreign relations.

ABSTRACT
On Nov.11, 2001, Taiwan obtained the accession of World Trade Organization and became a formal member of WTO on Jan 1st of 2002. As a member of WTO, Taiwan has equal rights to participate in the setting of global trade rules as well as sharing the benefits of liberalization. In the meantime, Taiwan must fulfill its WTO commitments completely, whether resulting from its bilateral and multilateral negotiations or from its standard WTO obligations. The accession to WTO means to Taiwan a big impact on all aspects of its general economics, people¡¦s everyday living as well as industrial policies.
After 35 years of development, Export Processing Zone (EPZ) has emerged from focusing on traditional labor-intensive industry to capital and technical intensive industry then to global logistic type of industry. Facing the impact of WTO, the need to make next transition is becoming even more urgent now. In an effort to upgrade the industry and strengthen the competence of the country, the government has assigned another responsibility on EPZ by expanding its range of function from pure manufacturing to high value-added economics activities like Off-Territory Shipment Center, Logistics Center, Software Design Center, etc.
Mainland China obtained its WTO membership same time as Taiwan. They are leveraging their fast economic development and huge market potential to attract foreign and Taiwanese investments. Hence we can not exclude the influence of Mainland China while trying to discuss the WTO impacts on EPZ and how EPZ can face the big change of economic environment.
This study has set following three topics:
1. The impact on EPZ as a result of Taiwan¡¦s accession to WTO.
2. What is the outlook of EPZ¡¦s new positioning.
3. Suggestions to the government, EPZ Administrations and Companies inside and outside of EPZ.
This study will firstly make a brief review on both WTO and EPZ. Then explore the impacts, as well as the opportunities and threats, of WTO on both the industries in Taiwan and in EPZ. Then we will study the two major directions of EPZ¡¦s new positioning: (1) New developments as a result of new economic relationship between Taiwan and Mainland China, this includes Off-Territory Shipment Center, a base for China¡¦s companies to enter Taiwan, and the ¡§deep processing¡¨ that utilizes the advantage of integrating operations across the Taiwan Strait, and (2) New developments as a result of the expanding of EPZ¡¦s new service function, that includes R&D center, headquarter for off-shore Taiwanese companies, International Trade Companies, center for specific industry cluster and logistic center, etc.
Based on the results of this study, we have made suggestions to the government, the EPZ Administration and companies inside and outside EPZ. The suggestions to the Government are: Try to form Free Trade Zone with Asia-Pacific countries and also form a ¡§Greater China Free Trade Zone¡¨ with Mainland China and Hong Kong under the condition that the political disputes are settled. Also to promote business opportunities in the developing countries by utilizing Taiwan¡¦s strengths of manufacturing and technology. Regarding the suggestions to the EPZ Administration and companies inside and outside EPZ, the suggestions are all regarding how EPZ can strengthen their service and improve the investment environment, and how companies are to fully utilize these EPZ improvements.
The conclusion of this study shows following four items:
1. The accession of Taiwan to WTO is not only a crisis for EPZ, but also an opportunity.
2. EPZ has built up sound infrastructure and set the direction for its new positioning to face this challenge.
3. Whether the new positioning is fulfilled and new investment poured in will decide if the next phase transition of EPZ is successful or not.
4. EPZ acted as the pilot model for Taiwan¡¦s economic success 35 years ago, we are hoping it acts one more time the same model for Taiwan¡¦s next economic re-form.

An Exploration of Key Factors of Attracting Investments in Kaohsiung Export Processing ZoneHuang, Ti-fen 11 July 2008 (has links)
Since the EPZ was set up in 1966, it has attracted foreign investment, introduced technology, opened up foreign trade and provided employment opportunities. When EPZ was first set up, it had every kind of investment-rewarding regulations, ¡§One-stop Window¡¨ administrational measures, so it could attract a lot of foreign and overseas Chinese capitals. But, after 2 years, the 68-hectare area was not enough for using. The EPZA has continuously expanded the zones up to 9 so far: the total area is about 576.81 hectares. The EPZs are export-oriented, their products are all exported, and the professions have increased step by sep, including trade, logistics and warehouses, software consulting and related industries. Its capital resources were mainly from Europe, U.S., Japan and Hong Kong, but converts into domestic mostly now, with 47.79%, the highest ratio. The Zones¡¦ industrial structure also changed from the original garments, plastics and leather with more than 55% to electronics & electric machinery with 80% the most now.
The Export Processing Zone Administration (EPZA) has also coped with the era trend changes by innovating the policies and functions, such as efforts in zone transformation, deregulations, trade liberalization and industrial clustering. As the accumulations of Taiwan¡¦s capital and technology and the enormous changes both in global politics and economy, the in-zone enterprises have also changed the industrial structures and production processes, walk out the OEM shadows and walk in the ODM, so as to produce and do marketing by themselves and to expand the markets. They have transformed from labor-intensive industries of garments, plastics, leather to capital-intensive high-tech industries of IC, LCD, optics, precise tools, information software and digital content and so on. When Taiwan¡¦s producing costs are rising little by little, the enterprises form all over the world are moving to the mainland China and the booming southeastern Asian countries to reduce costs and grip the markets. It is the question how to mold the more suitable investment environment to lure the Taiwanese enterprises come back home and the foreign investment turn around to Taiwan.
This study made the in-depth interviews and did the questionnaires to scholars, government agencies and the industrial circle for over 30 copies. This study also analyzes the key factors of attracting investment by AHP hierarchical analysis method. The results revealed that, firstly, the enterprises¡¦ interactions and the neighboring of customers, the benefits of industrial cluster and the completion of supply chain of down and up stream, are vital to attract investment. Secondly, the completion of the in-zone infrastructure is the most important key factor for attracting investment. Thirdly, The EPZA ¡¥s favorable measures and administrative efficiency are also the prior considering factors.
This study suggested that the administration units should upgrade the functions of their in-zone administrative steps, build the modern facilities of the infrastructure and attach importance to the living functions, strengthen the cooperation between industries, governments and schools, and propagate the investment-rewarding measures offered by governments to the enterprises, so that the governments¡¦ good policies can truly do favors to the in-zone enterprises, and thus construct the zones¡¦ better investment environment and attract investment.
