The Reasons for and the Impact of Antidumping Protection: The Case of People's Republic of China

Over the past few decades, the liberalization in international trade has progressed at a rapid speed. While tariffs and quotas have been and continue to be reduced, another type of trade barrier, antidumping, is being used more and more frequently as a measure of protection. This paper focuses on the case of China, explores the characteristics, the reasons for and implications of antidumping. China is the largest targeting economy of antidumping (AD) trade disputes and there is evidence that China is more susceptible to antidumping than other economies, even after controlling for factors such as the non-market economy (NME) status. Our paper analyzes the reasons for China being so broadly and intensively targeted. In particular, the domestic characteristics of exports structure and industrial structures are examined. Our analysis also reveals that foreign direct investment (FDI) may be a significant factor explaining AD cases against China. There is also evidence that low concentration ratios in Chinese industries have contributed to the competitive price and low profit margins. An earlier draft of this paper was presented at the APEC Capacity-Building Workshop on Quantification of NTMs and Trade Facilitation, October 8-10, 2003, in Bangkok, Thailand.

A Sketch-Based Educational System for Learning Chinese Handwriting

Learning Chinese as a Second Language (CSL) is a difficult task for students in English-speaking countries due to the large symbol set and complicated writing techniques. Traditional classroom methods of teaching Chinese handwriting have major drawbacks due to human experts’ bias and the lack of assessment on writing techniques. In this work, we propose a sketch-based educational system to help CSL students learn Chinese handwriting faster and better in a novel way. Our system allows students to draw freehand symbols to answer questions, and uses sketch recognition and AI techniques to recognize, assess, and provide feedback in real time. Results have shown that the system reaches a recognition accuracy of 86% on novice learners’ inputs, higher than 95% detection rate for mistakes in writing techniques, and 80.3% F-measure on the classification between expert and novice handwriting inputs

Does College Education Promote Entrepreneurship in China?

Abstract(#br)There is no consensus on the impact of education on entrepreneurial choice in both theory and empirics. China’s Higher Education Expansion (HEE) policy initiated in 1999 provides us a unique opportunity to identity the causal relationship between college education and entrepreneurship by exploiting the Fuzzy Regression Discontinuity Design (FRDD) approach. In this paper, we use the China Household Income Project (CHIP) 2013 database, finding that China’s HEE policy significantly increases the probability of obtaining college education by 12%. There is suggestive evidence that college education decreases overall and self-employed - type of entrepreneurial choices, but increases boss-type activities; none of the coefficients are precisely estimated, though. Our results are..

Photoinduced coupled twisted intramolecular charge transfer and excited-state proton transfer via intermolecular hydrogen bonding: a DFT/TD-DFT study

We discuss theoretically the geometric and electronic structure properties of the thiazolidinedione derivative A and its hydrogen-bonded complex in dimethylformamide (DMF) solution in the S0 and S1 states. To gain insight into the photoinduced coupled excited-state proton transfer (ESPT) and twisted intramolecular charge transfer (TICT) associated with intermolecular hydrogen bonding, the potential energy profiles are provided along the Osingle bondH bond and the twisted angle. It is predicted that TICT in S1 can facilitate ESPT initiated by intermolecular hydrogen-bond strengthening in the S1 state. The coupling of ESPT and TICT is energetically preferable

Identification of PTPN22 as a potential genetic biomarker for abdominal aortic aneurysm

Abdominal aortic aneurysm (AAA) is a severe life-threatening disease that is generally asymptomatic and is diagnosed at a very late stage. The genetic component underpinning AAA is considerable, with an estimated heritability of up to 70%. Therefore, identifying genetic biomarkers for AAA is valuable for predicting high-risk populations. We used integrative bioinformatics and cellular AAA model-based validation to reveal that the gene encoding protein tyrosine phosphatase non-receptor type 22 (PTPN22) may be a potentially useful diagnostic biomarker for AAA. Integrative bioinformatics analyses of clinical specimens showed that PTPN22 expression was consistently upregulated in aortic tissues and peripheral blood mononuclear cells (PBMCs) derived from patients with AAA. Moreover, transcriptomics data revealed that PTPN22 is a potential biomarker for AAA with limited diagnostic value in patients with thoracic aortic aneurysm/dissection. Single-cell RNA sequencing-based findings further highlight PTPN22 expression in aortic immune cells and vascular smooth muscle cells (VSMCs) is consistently upregulated in patients with AAA. A cellular AAA model was eventually employed to verify the increase in PTPN22 expression. Collectively, the results indicate that PTPN22 could be a potentially useful diagnostic biomarker for AAA
