Spotlight on an emerging market: Assessing the footwear and apparel industries in Vietnam
Authors: Buchanan F. Robert , Anwar Syed Tariq , Tran Thien Xuan 
Published: December 2012

AbstractMultinational corporations and foreign direct investment have played a key role in Vietnam's transformation into a high‐potential, full‐scale manufacturing emerging market. Yet, there are few US companies operating in Vietnam, even though trade relations between the two nations have been normalized since 1995 and English is now the second language of choice in Vietnamese business circles. To date, neither Vietnam's status as an emerging market nor the growing sophistication of its businesses and consumers have been well investigated. Recent research and interviews with Vietnamese executives reveal that Vietnamese factories and value chains have undergone substantial transformation since their turbulent early days, and the nation's low‐cost labor pool makes it a desirable manufacturing location for the footwear and apparel industries. The challenge for such an emerging market is to leverage its current competitive advantage into a sustainable development model. To that end, businesses, policymakers, and government will need to deploy a long‐term strategy that will bring the domestic infrastructure and education to the next level. © 2013 Wiley Periodicals, Inc.
Meeting the global imperative of local leadership talent development in Hong Kong, Singapore, and India
Authors: Dunnagan Kelly , Maragakis Mireille , Schneiderjohn Nicole , Turner Cameron , Vance Charles M. 
Published: December 2012

AbstractAs companies continue to expand abroad, there remains a paramount challenge of ensuring strategic control to meet company standards and goals and to coordinate global operations. Traditionally, such control has been maintained by sending tried and true managers from company headquarters as expatriates to head up foreign operations. But in the face of this costly traditional approach for leadership staffing in foreign operations, there is increased awareness among multinational firms that their potential leadership talent is not restricted by their headquarters' national boundaries. MNCs are increasingly looking to their employees worldwide as a viable source of future talent for leadership staffing throughout their global operations. The results of field interviews with local leaders of American firm subsidiaries located in Singapore, India, and Hong Kong revealed four key local leadership development approaches: reinforcing a company culture of leadership development, identifying and codifying leadership talent, enhancing high potentials' visibility, and developing pervasive mentoring relationships. The cases examined here show that talent identification and development are essential elements of an effective long‐term talent management strategy that should be ingrained within a company's deep cultural values and priorities, as well as reinforced by performance evaluation and reward systems. © 2013 Wiley Periodicals, Inc.

AbstractOver the last two decades, the nature and practice of global business have radically changed, necessitating a new business model for achieving organizational excellence. To keep abreast of worldwide developments and stay ahead of the competition, enterprise leaders must take an expanded view of global business built on six cornerstones: the union of mission, policy, and strategy; attention to culture; a combination of technology, innovation, and creativity; the development of human capital; motivational leadership; and consideration of the overarching business environment. © 2013 Wiley Periodicals, Inc.
Effect of Different Counterions of the Manganese Salt as Catalyst on the Kinetics of Resorcinol‐Based Belousov–Zhabotinsky Reaction
Authors: Ganaie Nadeem B. , Peerzada Ghulam M. , Shah Ishfaq A. 
Published: December 2012

ABSTRACTKinetic studies on the Belousov–Zhabotinsky (BZ) system with various metal ions as catalysts have been carried out for a long time, but the effect of counteranions associated with the metal ion solution used as the catalyst in the BZ reaction has not been explored. Thus, we have chosen some metal salts as catalysts having the metal ion (Mnn+) but with various anions to study the role of different anionic moieties of catalyst on the oscillatory behavior of the resorcinol‐based BZ reaction system. It is found that organic‐type anionic moieties marginalize the role of organic substrates in the reaction system. On the other hand, the inorganic counterions of the catalyst show salting out effects, thereby increasing the ionic strength, which affects the mobility (diffusion) of the ions in our system performed under batch conditions.

Published: December 2012

AbstractDiode lasers are by far the most efficient lasers currently available. With the ever‐continuing improvement in diode laser technology, this type of laser has become increasingly attractive for a wide range of biomedical applications. Compared to the characteristics of competing laser systems, diode lasers simultaneously offer tunability, high‐power emission and compact size at fairly low cost. Therefore, diode lasers are increasingly preferred in important applications, such as photocoagulation, optical coherence tomography, diffuse optical imaging, fluorescence lifetime imaging, and terahertz imaging. This review provides an overview of the latest development of diode laser technology and systems and their use within selected biomedical applications.670 nm external cavity diode laser for Raman spectroscopy built on a 13 × 4 mm2 microbench (Copyright FBH/Schurian.com).
On the Formation and Electropolymerization of a Star Copolymer With Peripheral Carbazoles
Authors: Cao Peng‐Fei , Felipe Mary Jane , Advincula Rigoberto C. 
Published: December 2012

AbstractUtilizing a hyperbranched cored ring‐opening polymerization of caprolactone, carbazole peripheral groups are extended to afford electropolymerizable star‐like copolymers. Different arm lengths are obtained on the basis of different degrees of polymerization from the polyethyleneimine core. This is confirmed by NMR and Fourier transform IR (FTIR) spectroscopy, size‐exclusion chromatography (SEC), and quantitative spectral characterization. Atomic force microscopy (AFM) imaging shows two distinct particle aggregation characteristics, before and after functionalization with carbazole groups. Cyclic voltammetry verifies the electrochemical cross‐linking properties. The results indicate that the conformational freedom of the electroactive peripheral functional groups can be controlled. Moreover, an interesting “loop effect” together with solid‐state polymerization is observed.

AbstractA printed microstripline‐fed parallelogram monopole antenna for wideband applications is presented.This antenna is composed of a parallelogram monopole, a ground plane with three symmetrical parasitic elements, and a 50‐Ω microstrip feedline. By using short‐circuited parasitic elements including a symmetrical parallelogram patch and a pairs of strip lines, the proposed antenna can excite extra resonate modes to achieve wideband operation. The measured results show that the proposed antenna offers a large impedance bandwidth for 10‐dB return loss is 4.74 GHz (1.82–6.56 GHz), corresponds to fractional bandwidth of 113% for central frequency at 4.19 GHz, and can cover the personal communication services, IMT‐2000, 2.4/5.2/5.8 GHz wireless local area network, and 2.5/3.5/5.5 GHz worldwide interoperability for microwave access standards.

Published: December 2012

AbstractAn isolation technique for two small‐size triband wireless wide area network (WLAN) multiple‐input multiple‐output (MIMO) laptop computer antennas covering the 2.4/5.2/5.8 GHz bands is presented. The proposed WLAN MIMO antennas have measured isolation of better than −21 dB in the 2.4 GHz band and −32 dB in the 5.2/5.8 GHz bands in this study. In addition to enhanced isolation achieved, good antenna efficiencies of better than about 70 and 90%, respectively, in the 2.4 GHz and 5.2/5.8 GHz bands are obtained for the two antennas. The WLAN MIMO antenna array having a planar structure of size 9 × 55 mm2 is to be mounted at the top edge of the supporting metal plate of the laptop display. The two antennas can be fabricated at low cost on a thin FR4 substrate and are of a simple structure comprising a driven strip and a shorted strip, which provides two wide operating bands to cover the 2.4 and 5.2/5.8 GHz bands. Between the two antennas, there is an isolation element formed by a protruded ground plane and a spiral open slot embedded therein. The isolation element leads to enhanced isolation between the antennas in the 2.4/5.2/5.8 GHz WLAN bands and good antenna efficiencies for the antennas as well. Details of the isolation technique for the WLAN MIMO antennas are described, and the obtained results are presented and discussed. © 2012 Wiley Periodicals, Inc.

Published: December 2012

AbstractIn this article, a novel wideband wavelength conversion is demonstrated using a highly nonlinear fiber consisting of a fluorine‐doped fiber that has a high delta core and surrounded by a deeply depressed ring as opposed to the use of photonic crystal fibers.The wavelength conversion range is from 1460 to 1640 nm, which covers the S‐, C‐ and L‐bands of the optical network. The interacting waves consist of an arrayed waveguide grating tuned dual‐wavelength fiber laser output together with a tunable laser source signal.

Published: December 2012

AbstractRecently, the improved electric field integral equation (IEFIE) is proposed to efficiently solve large dense complex linear system arising from three‐dimensional electromagnetic scattering problems. In this article, the shifted symmetric successive over‐relaxation preconditioner is constructed which combines the near‐field matrix of the EFIE and the principle value term of the magnetic field integral equation. The present method can achieve stably faster convergence of iterations than IEFIE with low cost for construction and implementation. Numerical results demonstrate the efficiency and validity of the present method. © 2012 Wiley Periodicals, Inc.

Effect of loop diameter on the performance of MKR‐based dual‐wavelength erbium‐doped fiber laser
Authors: Sulaiman Azlan , Harun Sulaiman Wadi , Norizan S. F. , Dimyati K. , Ahmad H. 
Published: December 2012

AbstractA dual‐wavelength Erbium‐doped fiber laser (EDFL) is demonstrated using a 1.5‐m long EDF with a microfiber knot resonator (MKR) structure at the output end. The MKR is fabricated by heating and stretching a 3‐cm long piece of EDF to form a microfiber, which is then manipulated to create a knot. The performance of the EDFL is investigated for two different MKR loop diameters. At a loop diameter of 4 mm, dual‐wavelength laser is obtained at 1532.4 and 1556.0 nm with peak powers of −7.5 and −7.1 dBm and the corresponding optical signal‐to‐noise ratios of 22 and 32 dB, respectively. As the MKR diameter is reduced to 2 mm, the operating wavelength of laser shifts to a shorter wavelength, especially for the second lasing with a significant drop in output power due to the bending loss, which is more pronounced at smaller loop diameter. The slope efficiency of the EDFL drops from 0.55 to 0.09% as the MKR diameter decreases from 4 to 2 mm. © 2012 Wiley Periodicals, Inc.

Published: December 2012

AbstractThis article presents a novel method for the design of tunable and miniaturized power dividers.It is based on three impedance transformers and requires a single bias voltage command, instead of three commands needed for more classical designs. This single voltage simplifies the power divider in terms of design and use. For a proof‐of‐concept, a power divider with a 950 MHz working frequency has been designed, with two output varactors tuning the power repartition through the two output ports. Thanks to the developed approach, the miniaturization ratio between our power divider and the Wilkinson one is equal to 75.5% at 950 MHz. Measurements show a wide tunable power ratio between the two output ports (1:3.4), a very good matching in the pass band (return loss better than 16 dB), low insertion loss (0.6 dB), and a tunable bandwidth of ±15%. © 2012 Wiley Periodicals, Inc.

Low voltage‐low power full‐band UWB receiver front‐end
Authors: Lee Ji‐Young , Yun Tae‐Yeoul 
Published: December 2012

AbstractThis article proposes a low‐voltage, low‐power, low‐noise, wideband receiver front‐end consisting of a low‐noise amplifier (LNA) and a mixer. The LNA stage uses a current‐reuse technique for low‐power consumption and high gain. A switched biasing technique is then used to reduce the flicker noise of the mixer. A bulk injection structure is adopted for low‐voltage operation of the mixer. The proposed receiver front‐end achieves input impedance matching of less than −10 dB from 3.1 to 10.6 GHz, a minimum noise figure of 4.9 dB, and a maximum power gain of 17.7 dB while consuming 8.25 mW from 6.87 mA and 1.2 V. This receiver front‐end is fabricated using a 0.18‐μm CMOS process. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:278–281, 2012; View this article online at wileyonlinelibrary.com.

Measurement accuracy enhancement using an optical probe system for electrically small MIMO antennas
Authors: Chung Jae‐Young , Hong Wonbin 
Published: December 2012

AbstractWell‐known measurement inaccuracy issues for electrically small multiple‐input–multiple‐output (MIMO) antennas incurred by conventional metallic cable and feed effects are mitigated by adopting an optical probe based measurement method.To demonstrate this, a closely packed MIMO antenna consisting of a pair of spirally wound antenna elements is designed and characterized using both the metallic cable feeding and the optical probe feeding methods. The measured MIMO antenna parameters, such as envelope correlation, radiation efficiency, and diversity gain, ascertain significantly improved agreement with simulation, when the optical probe feeding method is used. © 2012 Wiley Periodicals, Inc.

Published: December 2012

AbstractThis article presents a novel metal bezel antenna structure and its performance in user vicinity. The antenna is designed by keeping in mind the insensitivity in usage environments. In the antenna structure, a mobile chassis and a bezel are combined as one antenna element. Symmetrical feeding is used to excite the antenna. The characteristics of the metal bezel are compared with those of a conventional planar inverted‐F antenna in terms of user effect at E‐GSM band (880–960 MHz). Both antennas are measured and compared with four different hand phantom grips representing a browsing mode. The grips are designed so that the chassis is under the hand phantom in different variable usage conditions. Results are compared in terms of S11, total efficiency, total body loss, radiation efficiency, reflection loss, and in Smith chart presentation. Finally, antenna structures are compared with hand and head phantom measurements representing a calling mode. The comparison is done in terms of average total body loss. The used hand grips are the same as in the case of the hand phantom measurements. © 2012 Wiley Periodicals,v Inc.
