Sectors sensitive to carbon prices, e.g., the power generation sector and the iron and steel industry, are given priority to be covered by the ETS. Interregional carbon trading should be carried out as early as possible. The cap of the ETS should be based on China's carbon intensity reduction target with the floor carbon price for the market being set in the beginning. Suggestions on the infrastructure of ETS are also proposed, including the national wide carbon measuring, reporting, verification system building. account registration system and the legislation to national展开更多

The research results indicate that there is long-term dynamic and equilibrium relationship between foreign trade and economic growth, and the economic growth is the Granger cause of trade import. Since 1979, rapid growth of economy motivates the expansion of trade import, but the pulling effect of import on economic growth is not evident. In addition, trade import promotes economic growth in the long run. But we can see that from the economic data in Shanghai that the promotion has not become the source motivate force of growth for trade expert.展开更多

At a time of economic crisis, Slovakia acceded to the adoption of a common currency--the euro. Prior to the adoption of the euro, apprehensions were raised due to currency decreased export from Slovakia to countries V4. In this article, author analyses the mutual foreign trade of Slovakia with countries of V4 for all commodities in standard international trade classification (SITC) codes. The analysis covers the time before the adoption of the euro from 2004 to 2008 and after the adoption of the euro in the years from 2009 to 2013. It compares the percentage change over the previous year, the balance of foreign trade, and foreign trade turnover. The same analysis is also done for the period prior to the adoption of the euro as a whole and after the adoption of the euro. In the calculations, data from UN Comtrade Database were used, which are indicated in USD. The results indicate that in the transition to the common currency, the euro did not mean for Slovakia worsening trade with V4 countries. Economies of these countries have long been linked and even the possibility of its own monetary policy does not endanger Slovakia's export to these countries.展开更多

A large number of susceptibility genes and key biological pathways in disease development have been identified. So far, studies in inflammatory bowel diseases, and in particular Crohn’s disease, have been especially successful in def ining new susceptibility loci using the GWAS design. The identification of associations related to autophagy as well as several genes involved in immunological response will be important to future research on Crohn’s disease. In this review, key methodological aspects of GWAS, the importance of proper cohort collection, genotyping issues and statistical methods are summarized. Ways of addressing the shortcomings of the GWAS design, when it comes to rare variants, are also discussed. For each of the relevant conditions, fi ndings from the various GWAS are summarized with a focus on the affected biological systems.展开更多

Since the self-similar queuing system performance analysis is often carried out under the condition of infinite buffer, it is difficult to deduce the upper boundary of buffer overflow probability. To overcome this shortcoming, a simple overflow condition is proposed, which defines a buffer overflow occurrence whenever the arrival rate exceeds the service rate. The analytic formula for the buffer overflow probability upper boundary is easily obtained under this condition. The required bandwidth upper boundary with long-range dependence input and determined overflow probability is then derived from this formula. Based on the above analytic formulas, the upper boundaries of the admission control regions for homogeneous and heterogeneous long-range dependence traffic sources are separately obtained. Finally, an effective admission control scheme for long-range dependence input is proposed. Simulation studies with real traffic have confirmed the validity of these results.展开更多

Maritime transportation is the backbone of contemporary world trade and therefore special attention should be paid to all subjects concerning this mode of transportation. It is also necessary to complement maritime transportation by other modes, such as rail and/or truck (road). This article deals with the problems of maritime transportation and provides the summary of recent developments, trends and statistics mainly on transatlantic maritime routes (Europe to US). Besides maritime transportation, this thesis also reviews the trends and statistics of rail and truck (road) transportation in US and Europe. The authors considers four Czech biggest cities (points of origin), five European ports, eight US ports and 10 biggest cities in US (points of destination). The adapted TCMMSP (transnational collaborative multi-mode shipping problem) is applied to this case study and it seeks to solve the transportation of a set of five shipments with unique O-D (origin-destination) pairs and volume. The end of the thesis summarizes the results and analyses the average costs, optimal set volume, optimal shipment routing and port analysis.展开更多

The factors affecting successful accounting information are two variables including accounting professional and accounting information system (AIS) competency. Population and sample of this research is the companies listed in the Stock Exchange of Thailand (SET). A questionnaire mail was used for collecting the data from chief accountant officer of the companies listed in the SET. The results indicate that accounting professional has a positive significant effect on successful accounting information in all dimensions including effective planning, efficient controlling, and promoting decision and communication. Moreover, AIS competency has a positive significant effect on successful accounting information only in dimension of promoting decision and communication. Overall, the results indicate that internal resource and capabilities including accounting professional and AIS competency are the primary factors that influence successful accounting information of Thai-listed companies.

To protect the free trade world economic system, China has stood up to fight this trade bullying. When the US administration continued with harsher actions, the escalation in trade friction increased the potential harm for both countries. China has been very clear that Trump's trade tariffs cannot improve the bilateral trade imbalance. Tit-for-tat ought to be a last resort but China is open to talking. Now the ball is in Trump's court. As two big,influential economies, China and the US should calm down and go back to negotiating table to avoid a trade war trap.

Thus, this research aimed to examine the relationship CSR and economic performance of the companies of corporate sustainability index (ISE) of mercantile and futures exchange of Silo Paulo stock exchange (BM&FBOVESPA). The amount of companies allowing online access to their responses of the ISE questionnaire determined the sample of this research. Thus, for the study period from 2011 to 2012, it has been possible to access the responses of 12 companies, composing the overall sample of this research. The results of the regression analysis allow to statistically assert that for the sample used, environmental performance (EP) contributes to improving economic performance, measured by all financial metrics used: return on equity (ROE), return on assets (ROA), and net profit (NP). Statistically, it is only possible to say that social performance (SP) contributes to improving NP. In terms of market metrics, none of the null hypothesis was rejected, i.e., in any cases, it has been possible to affirm, on a statistical base, that SP and EP contribute to improving the market value (MV) and systematic risk. Thus, it is understood that the stakeholder theory has potential to explain the Brazilian situation regarding the aspects of CSR and financial ones under the accounting and the shareholder theory explains this relation, when viewed with the aid of market measurements.展开更多

Up to now, the international fur industry has not been thoroughly described or analyzed. A major reason is the rather limited availability of national and international statistics about the fur sector. This article analyzes the production and international trade in fur based on information from official statistics, trade associations, companies, scientific papers and reports, interviews with experts, etc.. Markets and market conditions play a very important role with regards to the fur sector, and the price of fur is volatile in the short and long run. A new world trade pattern and international specialization have emerged in recent years. The comparative advantages of the fur sector change along the fur value chain, while China's position on the global fur market has changed significantly.展开更多

文摘The fur industry and the entire fur cluster are in many ways an interesting and instructive example from which many lessons can be learned. Up to now, the international fur industry has not been thoroughly described or analyzed. A major reason is the rather limited availability of national and international statistics about the fur sector. This article analyzes the production and international trade in fur based on information from official statistics, trade associations, companies, scientific papers and reports, interviews with experts, etc.. Markets and market conditions play a very important role with regards to the fur sector, and the price of fur is volatile in the short and long run. A new world trade pattern and international specialization have emerged in recent years. The comparative advantages of the fur sector change along the fur value chain, while China's position on the global fur market has changed significantly.
