Attentional suppression is in place before display onset

Huang, C.; Donk, Mieke; Theeuwes, Jan

Recent studies have shown that observers can learn to suppress a location that is most likely to contain a distractor. The current study investigates whether the statistically learned suppression is already in place, before, or implemented exactly at the moment participants expect the display to appear. Participants performed a visual search task in which a distractor was presented more frequently at the high-p...

A proposed experimental test of proton-driven plasma wakefield acceleration bas...

Xia, G.; Caldwell, A.; Lotov, K.; Pukhov, A.; Assmann, R.; Zimmermann, F.; Huang, C.; Vieira, J.; Lopes, N.; Fonseca, R. A.; Silva, L. O.; An, W.

Proton-bunch driven plasma wakefield acceleration (PDPWA) has been proposed as an approach to accelerate electron beam to TeV energy regime in a single plasma section. An experimental test has recently proposed to demonstrate the capability of PDPWA by using proton beams from the CERN SPS. The layout of the experiment is introduced. Particle-in-cell simulation results based on the realistic beam parameters are ...

Determinants of exports in China: A microeconometric analysis

Huang, C.; Zhang, M.; Zhao, Y.; Varum, C.A.

Based on data from more than 100,000 Chinese manufacturing firms, this study explores the reasons for the recent surge of manufacturing exports from China. Research and Development (R&D) investment has not been a contributing factor to the export success of Chinese firms, even in high-technology sectors. Although exportation of high-technology products has been dominated by foreign manufacturing firms, domestic...


The reform of S&T in China: policy & performance

Huang, C.; Varum, C.A.; Gouveia, J. B.

China’s transformation into a dynamic market economy and its integration into global economic system have been dramatic in the last quarter of the 20th century. In the transformation and rise of China, the policy towards innovation played an increasing role. The paper investigates in detail China's innovation policy in seven categories: reform in the governance model, transformation of the public S&T institutio...


Why the manufacturing firms in developing countries can be competitive? The evi...

Huang, C.; Zhang, M.; Zhao, Y.; Varum, C.A.

Based on the data of more than 95,000 Chinese manufacturing firms, this study explores the reasons for the recent surge of manufacturing exports from China. Contrary to common belief, neither unit labor cost nor Research and Development (R&D) investment has been a contributing factor to the export success of Chinese firms, even in hightechnology sectors. Although exportation of high-technology products has trad...



Scientific productivity paradox: the case of China's S&T system

Huang, C.; Varum, C.A.; Gouveia, J.B.

In 1985 China began the reform of its Science & Technology (S&T) sector inherited from the planned economy. To disclose the impact of the drawn-out reform on the efficiency of the whole sector, we measure the scientific productivity of China's S&T institutes. The analysis is based on R&D input and output data at the country aggregate and provincial level. We utilize Polynomial Distributed Lag model to uncover t...


The transition of Chinese S&T institutes since 1980s: policy, performance and i...

Huang, C.; Varum, C.A.; Li, Z.; Gouveia, J. B.

In 1985 China began its reform on the Science & Technology (S&T) sector which was inherited from a planned economy. The reform over the past 20 years is deemed to be a decisive factor in China’s science and technology progress. The paper first argues that two fundamental tasks of China’s S&T sector reform are to enhance scientific productivity and strengthen the industry-academic relationships. Subsequently, th...


Organization, programme, and structure: an analysis of Chinese innovation polic...

Huang, C.; Amorim, C.; Spignolio, M; Gouveia, B.; Medina, A.

The paper first identifies the stakeholders involved in the design and implementation of China’s innovation policy and compares them with different government systems in selected Organization for Economic Co-operation and Development (OECD) countries. In order to disclose the relative strength and weaknesses inside China’s innovation policy framework, we proceed to utilize policy practices in the OECD countries...
