This study aims to inform prospective listing firms, investors and regulators of the unique drivers of Chinese initial public offering (IPO) pricing on the Hong Kong Exchange.

Using a hand-collected IPO dataset, we investigate whether information uncertainty or investor exuberance drives underpricing and Chinese IPOs’ performance from 2002 to 2015, including 114 state-owned enterprises (SOEs).

Contrasting with the “listing bubble” in the China domestic stock market, generated by the overoptimism of retail investors, we highlight a “placing bubble” among Chinese firms listed in Hong Kong. This is driven by institutional investors’ buoyant demand for Chinese IPO shares, particularly those of SOEs. Chinese listing firms employ discreet earnings management strategies with their working capital accounts to smooth pre-IPO earnings, which becomes apparent to the market only in the long term.

This study is the first to examine the pricing of sought-after Chinese IPOs among international investors, who face various restrictions when investing in the Chinese domestic stock market. Additionally, it is the first study to measure earnings management using hand-collected pre-IPO data in IPO underpricing studies.

The purpose of this paper is to design and measure an H‐plane substrate integrated waveguide (SIW) 72 GHz backfired horn antenna chip. The SIW horn was fabricated on a standard 0.5‐μm GaAs process with substrate thickness of 100 μm.

Planar SIW horn design method with standard GaAs circuit design rule was adopted. The input reflection coefficient and output antenna gain was simulated at the FEM‐based 3D full‐wave EM solver, Ansoft HFSS and measured at the Agilent E8361C Network Analyzer and Cascade 110 GHz probe station.

The measured input −6 dB bandwidth is about 0.9 GHz at a center frequency of 72.39 GHz. The maximum antenna power gain extracted from the path loss at 72.39 GHz is about −3.64 dBi.

Thin substrate exhibits larger capacitance and energy stores rather than radiates. Flat cutting restricts the arc lens design and results in the radiation plane mismatches to the air. Simple taper transition design makes the input bandwidth much narrower. The problems can be further improved by selecting thicker substrate and the multi‐section input CPW GSG pads to microstrip transition.

Unlike the traditional anechoic chamber, the antenna measurement station is exposed to the open space and chip antenna was supported by the FR4 substrate and the metal probing station plate. A fully characterization of the antenna open space environment before the measurement is needed.

An H‐plane SIW 72 GHz horn antenna was designed and studied. The antenna was using the GaAs 0.5‐μm MMICs process design rule includes the SIW designed cylindrical metal bars all being restricted in standard rectangular shape. Compare to traditional bulky waveguide horn antenna, the antenna chip size is only 1.8×1.7 mm². The on‐wafer measurement is conducted to measure the input return loss and the maximum antenna power gain of the on‐chip antenna. The designed on‐chip SIW horn antenna is useful for the integrated design of the E band GaAs MMICs single‐chip RF transceiver.

Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

The purpose of this paper is to introduce a new device with eddy current microscope (ECM) to test the invisible and buried subsurface flaws in metallic specimens.

When coil is excited by intermittent impulse signal, the eddy current effect happens among the tested metal specimen which is near the coil. Because of magnetic‐optic effect caused by eddy current magnetic field, the magnetic‐optic film changes the polarization direction of the passing linear polarization beam. The beam, containing the defects' information, can be accepted by charge‐coupled device (CCD) after being reflected through beamsplitter, and the imperceptible flaws in subsurface of mental product can be visually tested.

Integrating the eddy effect fully with Faraday's magneto‐optic (MO) effect can realize the visual non‐destructive testing for the subsurface defects.

Manufacturing defected specimens and improving the resolving power of the MO image remain difficult and need further research. A better image processing system needs to be developed to ascertain the characters of the defects.

After additional experiments, this device may find practical application on the inspection of flaws under the surface of metal specimens.

The device presented in this paper can detect the small defects that are hardly seen by eyes at the surface and the subsurface of metal specimens, and have them detected by the CCD.

This paper aims to conceptually argue that China's trade surplus with the USA is not good.

Net exporters (like China) give up current consumption in order to gain claims against future production. This paper argues that the reasons why China is trading current consumption for claims on future production are not good.

There are strong reasons to believe that China's trade surplus with the USA is not healthy for either China or the USA.

Other scholars have discussed the trading of the present for the future that is involved in trade surpluses, but no one (to the author's knowledge) has discussed when such a trade is good or bad.

An international marketing strategy can only be as good as its implementation. Because implementation becomes more and more difficult through changes in international relations, economic ideologies, pressures of competition and growing professional competence, the negotiations by which implementation largely takes place assume an increasing significance in the outcomes.

For the West, the opening up of China has raised the prospect of a vast market for a range of goods and services and their associated technologies. For the interested observer, it has provided an opportunity to obtain answers to issues which, since 1949, have been a source of constant speculation. China, coping with one in four of the world's population and organised according to a unique political experience, can hardly fail to stimulate interest and curiosity. The open‐door policy, whilst undoubtedly providing answers to many questions, has also raised many more which show the degree of difference between East and West, indicating the efforts in understanding that will have to be made by anyone wishing to establish relations with the Chinese. A recent publication on Trade with China began with the following sobering comment:

Songkhla Lake is the largest lake in Thailand along the Bay of Thailand, situated at latitude 7°08′ and 7°50′ north and longitude 100°07′ and 100°37′ east (Fig. 4.1). The lake covers an area of approximately 1,042km², and consists of four interconnected lake ecosystems (Ratanachai & Sutiwipakorn, 2005): Thale Noi (approximately 27km²), Thale Luang (approximately 473km²), Thale Sap (approximately 360km²), and Thale Sap Songkhla (approximately 182km²).

This paper aims to generate an obstacle free real time optimal path in a cluttered environment for a two-wheeled mobile robot (TWMR).

This TWMR resembles an inverted pendulum having an intermediate body mounted on a robotic mobile platform with two wheels driven by two DC motors separately. In this article, a novel motion planning strategy named as DAYANI arc contour intelligent technique has been proposed for navigation of the two-wheeled self-balancing robot in a global environment populated by obstacles. The developed new path planning algorithm evaluates the best next feasible point of motion considering five weight functions from an arc contour depending upon five separate navigational parameters.

Authenticity of the proposed navigational algorithm has been demonstrated by computing the path length and time taken through a series of simulations and experimental verifications and the average percentage of error is found to be about 6%.

This robot dynamically stabilizes itself with taller configuration, can spin on the spot and rove along through obstacles with smaller footprints. This diversifies its areas of application to both indoor and outdoor environments especially with very narrow spaces, sharp turns and inclined surfaces where its multi-wheel counterparts feel difficult to perform.

A new obstacle avoidance and path planning algorithm through incremental step advancement by evaluating the best next feasible point of motion has been established and verified through both experiment and simulation.

Post-acquisition control is a crucial factor affecting acquisition performance. We investigate how post-acquisition control strategy affects cross-border acquisition performance of Chinese multinational enterprises (MNEs) through a configurational perspective.

Based on 70 cross-border acquisition cases by Chinese MNEs, we adopt fuzzy-set qualitative comparative analysis (fsQCA) to study the combined effects of strategic control, operational control, institutional distance, cultural distance, relative capacity and business relatedness on the cross-border acquisition performance.

On the basis of fuzzy set analysis of multiple interdependent factors, we identify six configurations that are conductive to achieving high cross-border acquisition performance and two configurations that relate to the absence of high performance, thus shedding light on the casually complex nature of performance drivers of acquisitions.

This study provides a holistic, configurational approach to investigating cross-border acquisition performance by emerging market firms. Our results provide some compelling evidence that accounts for the causal complexity of post-acquisition control strategies and acquisition outcomes in the context of emerging economies.
