Foreign direct investment and China's bilateral intra-industry trade with Japan and the US
No full textThis paper analyzes dynamic changes of China's intra-industry trade with its major trading partners, Japan and the US, from 1980 to 2004. It also investigates to what extent foreign direct investment promoted intra-industry trade. The empirical results show that, while shares of China's intra-industry trade with both Japan and U.S rose substantially, its intra-industry trade with Japan has reached 35 per cent of the overall trade, considerably larger than 10 per cent with the US. Sino-Japan intra-industry trade concentrated in the electrical and machinery sectors accounted for 52 per cent and 46 per cent of overall trade respectively. On the other hand, it is in the chemical and food sectors where intra-industry trade represented a relatively large proportion of Sino-US trade, 50 per cent and 30 per cent accordingly in each sector. In addition, the analysis indicates that Japanese direct investment in China performed a significant role in enhancing intra-industry trade between Japan and China. However, it found no evidence that the US direct investment in China contributed to the growth of the bilateral intra-industry trade between the two countries.intra-industry trade; FDI; China

Some modifications of MPS method for incompressible free surface flow
No full textAs a Lagrangian mesh-free method, the Moving Particle Semi-implicit (MPS)[1] method is very suitable for simulating violent flows, such as breaking waves on free surface. However, despite its wide range of applicability, the original MPS algorithm suffers from some inherent difficulties in obtaining an accurate fluid pressure in both spatial and time domain. Different modifications to improve the method have been proposed [2-5] in the literature. In this paper, the authors developed a particle position shifting and collision handling technique which could effectively suppress the pressure fluctuation. In addition, a new version of “cell-link” neighbour particle searching strategy, which reduces about 7/9 (~78%) of the searching area compared with traditional “cell-link” algorithm, is proposed.The developed MPS method with the proposed modifications has been tested on two free surface flow problems: 2D dam break and liquid sloshing. The numerical results obtained are found to be in good agreement with the available numerical and experimental results. With the proposed modifications, the stability and accuracy of the pressure field are improved in spatial and time domains
Longicornus furcatus Fang & Xing 2018, sp. nov.
No full textLongicornus furcatus sp. nov. Figs. 7–9; 27–33 Description. Vertex yellowish brown with some black stripes. Eyes brown. Pronotum with irregular yellowishbrown stripes (Fig. 7). Face with frontoclypeus broadly yellowish brown dorsally, without dark transverse streaks on both sides (Fig. 9). External features as in generic description. Male genitalia. Male pygofer side broadly rounded in lateral aspect, with 7 long postero-ventral setae (Fig. 27). Aedeagal shaft short and robust, with pair of furcate processes arising from ventral margin near base; gonopore apical (Figs. 30, 31). Connective with arms nearly 1/3 length of stem (Fig 32). Measurement. Length (including tegmen): Ƌ, 5.4–5.6 mm; ♀, 6.1–6.4 mm. Type Material. Holotype: 1 ♂, China: Sichuan Prov., Ya’an, Erlangshan, 4 August 2005, coll. Zhonghui Zhou (GUGC); Paratypes: 2♂♂ 4 ♀♀, same data as holotype. Remarks. The new species is similar to L. flavipuncatus Li & Song, 2008, but can be distinguished from the latter by the pale dorsal part of the frontoclypeus and the short and robust aedeagus with a pair of furcate processes arising from the ventral margin near the base. Etymology. The species name is derived from the Latin word “ furcatus ”, referring to the aedeagal shaft with a pair of furcate processes.Published as part of Fang, Yongqin & Xing, Jichun, 2018, Review of the leafhopper genus Longicornus Li & Song (Hemiptera: Cicadellidae: Deltocephalinae) with description of two new species, pp. 435-442 in Zootaxa 4462 (3) on page 439, DOI: 10.11646/zootaxa.4462.3.9, http://zenodo.org/record/144173

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
A power flow mode theory based on a system's damping distribution and power flow design approaches
No full textA power flow mode theory is developed to describe the natural power flow behaviour of a dynamic system based on its inherent damping distribution. The system's characteristic-damping matrix is constructed and it is shown that the eigenvalues and eigenvectors of this matrix identify natural power flow characteristics. These eigenvectors, or power flow mode vectors, are chosen as a set of base-vectors spanning the power flow space and completely describe the power flow in the system. The generalized coordinate of the velocity vector decomposed in this space defines the power flow response vector. A time-averaged power flow expression and theorems relating to its estimation are presented.Based on this theory, power flow design approaches are proposed to identify energy flow patterns satisfying vibration control requirements. The mode control factor defines the measure of the correlation between a power flow mode and a natural vibration mode of the system. Power flow design theorems are presented providing guidelines to construct damping distributions maximizing power dissipation or to suppress/retain a particular vibration mode and/or a motion.The developed damping-based power flow mode theory is compared with a mobility-based power flow model. It is shown that the proposed power flow model provides insight into the power flow dissipation mechanisms in dynamic systems.Examples are presented to demonstrate the applicability of the power flow mode theory and the power flow design approach. These examples demonstrate the generality of the theory, including non-symmetric damping matrices, and illustrate power flow design applications through modifications of the system's damping distribution using passive and/or active control components
Exchange rate policy and the relative distribution of FDI among host countries
No full textThis paper examines the FDI-exchange rate nexus in the context of one FDI source and two host countries. It focuses on the effect of exchange rates on relative FDI inflows between the two host countries. The theoretical analysis shows explicitly that relative FDI inflows are a function of relative real exchange rates. In particular, if one host country devalues its currency against that of the source country more than the other does, FDI into the former country will be expected to increase relative to the other country. The theoretical inference is examined with Japanese FDI in manufacturing industries of China and ASEAN-4 (Indonesia, Malaysia, the Philippines and Thailand). The empirical results generally support the theoretical conclusion, suggesting that the real devaluation of the Chinese Yuan undercut FDI into the ASEAN-4.FDI; exchange rate; China; ASEAN-4
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
