Doctoral dissertations in logistics and supply chain management
Authors: Zachariassen Frederik , Stentoft Arlbjørn Jan 
Published: May 2010

PurposeThe purpose of this paper is to identify Nordic doctoral dissertations in logistics and supply chain management (SCM) published from the years 2002 to 2008. The paper then seeks to analyze the identified dissertations by categorizing them in various dimensions, including but not limited to subject, methodology, and type of contribution. Subsequently, the paper compares the analysis of the dissertations with results obtained in a previous study that also concerned Nordic dissertations only published from 1990 to 2001, effectively opening up for longitudinal interpretations.Design/methodology/approachThe paper is based on reviews of 70 Nordic doctoral dissertations within logistics and SCM published at relevant Nordic research institutions. All dissertations were reviewed according to a priori determined categories adopted from a similar, previous study in order to strengthen the validity of the longitudinal comparison.FindingsThis paper identifies a clear and significant trend towards: more dissertations based on a collection of articles than monographs; more dissertations focusing on manufacturing companies and fewer on carriers; a shift from a focal company perspective to more dyadic and supply chain‐related research and finally; and a decreasing focus on the philosophy in science.Research limitations/implicationsDespite the thorough method applied, there is possibility that a few dissertations might not have been identified in this paper.Originality/valueThis paper is a continuation of documenting the progress of doctoral work in logistics and SCM within the Nordic countries from the years 2002 to 2008.
Sleeping giant: Chinese teacher education system. Past, present and future (II)
Authors: Song Hongzhuan 
Published: May 2010

PurposeThe purpose of this paper is to explore how well Chinese teacher education positions itself in preparing qualified teachers for its vast K‐12 education system, especially in the transition from examination‐oriented to future‐oriented examination.Design/methodology/approachThe paper looks at literatures discussing background, strengths and weaknesses of current Chinese teacher‐training programs. It also employs a Delphi‐based scenario research method to explore plausible futures of curriculum design for teacher education.FindingsIn order to ensure its astonishing economic development and present itself as a constructive force for world betterment, it is crucial for China to carry on its ongoing educational reform, especially in the area of curriculum for its teacher‐training programs.Practical implicationsThe disciplinary curriculum currently employed in Chinese teacher education should be shifted to a trans‐disciplinary curriculum to produce future‐oriented, internationally‐prepared, and ICT‐savvy graduates with the high moral standards the country demands in its effort to play an important role on the international stage.Originality/valueThe research, while meriting the structured instruction displayed by the Chinese education system, argues that the system should strive to provide students with such skills as creativity, flexibility, initiative, leadership, all necessary in the globally connected future world. The second part of the paper will focus on four scenarios as a result of recent research among Chinese educators and administrators.
Why You Tube matters. Why it is so important, why we should all be using it, and why blocking it blocks our kids' education
Authors: Prensky Marc 
Published: May 2010

PurposeThe purpose of this paper is to highlight current changes in the way people communicate, and the role of You Tube in leading these changesDesign/methodology/approachThe approach takes the form of the author's observations and reflections.FindingsWith close to 100 million examples online, and growing exponentially, You Tube, and short video in general, are dramatically affecting the way in which today's Americans – especially young people – communicate and learn. In only five years, short video has moved from a medium for isolated, perhaps geeky young people to express themselves, to a two‐way medium used by mainstream people all over the world – including many experts and intellectuals – to share information and ideas. Today so much information is shared through video that, for perhaps 80 percent of Americans, reading and writing are rarely used skills, and becoming even more so.Practical implicationsWhile it is admitted that there remains a (relatively small) group for whom reading and writing will continue to be important, the question is “Should we continue to struggle to teach reading and writing to the great percentage of students, or should we focus on teaching clear communication of ideas through media that are easier to use?”Originality/valueThe paper provides a new perspective on the meaning of communication and the role of textual literacy in life and education in the near future.
Internationalization: the nexus of virtual worlds and reality
Authors: Roth Kate 
Published: May 2010

PurposeThis paper aims to describe the characteristics of virtual environments (VEs) that reinforce internationalization and to explore further implications for their utilization. Internationalization at universities is often argued as being key to developing global citizens. The use of VEs for global experiences is a relatively new phenomenon for universities. Understanding the aspects of VEs that develop global citizens will assist in their further development for internationalization.Design/methodology/approachThe paper presents a case study comparison of students and their experiences in the real world and VEs used in the Monash University Chinese Studies program. The student participants were interviewed using semi‐structured questions to establish the elements of the Monash Secondlife© Island contributing to their understanding of internationalization.FindingsThe case study concludes that students perceived the Monash Secondlife© Island useful for basic interactions in language learning and for students less confident with social interaction. Another outcome is the indication that students desire more technology (e.g. voice) to be used in subsequent developments.Originality/valueThe paper provides a unique analysis of the utilization of VEs to develop internationalization at university. It outlines the characteristics expected as part of internationalization, the current usage of VEs to develop internationalization, and articulates the specific characteristics that VEs enable as part of the internationalization process.

Authors: Menićanin Aleksandar B. , Damnjanović Mirjana S. , Živanov Ljiljana D. 
Published: May 2010

PurposeThe appropriate selection of a testing method largely determines the accuracy of a measurement. Parasitic effects associated with test fixture demand a significant consideration in a measurement. The purpose of this paper is to introduce a measurement procedure which can be used for the characterization of surface mount devices (SMD) components, especially devoted to SMD inductors.Design/methodology/approachThe paper describes measurement technique, characterization, and extracting parameters of SMD components for printed circuit board (PCB) applications. The commercially available components (multi‐layer chip SMD inductors in the ceramic body) are measured and characterized using a vector network analyzer E5071B and adaptation test fixture on PCB board. Measurement results strongly depend on the choice of the PCB; the behaviour of the component depends on the environment where the component is placed.FindingsThe equivalent circuit parameters are extracted in closed form, from an accurate measurement of the board‐mounted SMD inductorS‐parameters, without the necessity for cumbersome optimization procedures, which normally follow the radio frequency circuit synthesis.Originality/valueIt this paper, a new adaptation test fixture in PCB technology is realized. It is modeled and it has provided the extraction of parameters (intrinsic and extrinsic) of SMD inductor with great accuracy.

Authors: Krishnasamy Jegenathan , Chan Kah‐Yoong , Tou Teck‐Yong 
Published: May 2010

PurposeThe purpose of this paper is to address the influence of deposition process parameters. The substrate heating mechanisms are also discussed.Design/methodology/approachDeposition duration, sputtering power, working gas pressure, and substrate heater temperature on substrate heating in the direct current (DC) magnetron sputtering deposition process were investigated.FindingsResults from the experiments show that, in DC magnetron sputtering deposition process, substrate heating is largely influenced by the process parameters and conditions.Originality/valueThis paper usefully demonstrates that substrate heating effects can be minimized by adjusting and selecting the proper sputtering process parameters; the production cost can be reduced by employing a higher sputtering power, lower working gas pressure and shorter deposition duration.

Authors: Patil S. , Puri Vijaya 
Published: May 2010

PurposeThe purpose of this paper is to report the effect of bismuth oxide thick films of various thicknesses on the X band (8‐12 GHz) response of Ag thick film microstrip rectangular patch antenna.Design/methodology/approachThe effect of bismuth oxide thick film overlay of different thickness on Ag thick film microstrip rectangular patch antenna was investigated in the X band (8‐12 GHz). The change in the resonance frequency, amplitude, band width, quality factor, and input impedance of the antenna were studied. Using the resonance frequency the permittivity and conductivity of bismuth oxide thick film was measured.FindingsThickness of Bi2O3 thick film overlay dependent changes in the patch antenna characteristics is obtained. The resonance frequency shifts to higher frequency end due to overlay. The input impedance decreases due to the overlay. The dielectric constant of bismuth oxide thick film calculated from shift in resonance frequency shows thickness dependent values.Originality/valueThe microwave permittivity and conductivity of Bi2O3 thick film have been reported for the first time using overlay on thick film patch antenna. Thickness of overlay dependent tuning of the antenna has been achieved.

Published: May 2010

PurposeThe purpose of this paper is to share valuable information about low‐cost microwave circuit research with academic and industrial communities that work, or want to work, in this field.Design/methodology/approachScreen‐printing technology has been chosen as the fabrication method because of simplicity and low costs. Different materials and printing parameters were tested in four generations of microstrip lines. After obtaining a satisfactory fabrication method, passive microwave components were printed, assembled, characterized and modeled.FindingsResults demonstrated that the proposed low‐cost method allows fabricating low loss microstrip lines (15.63×10−3 dB/mm at 10 GHz), filters, inductors, and capacitors that work well up to 12 GHz.Research limitations/implicationsModel accuracy of inductors and capacitors can be improved. The use of more precise calibration and de‐embedding techniques is necessary. More components can be fabricated and modeled to increase the flexibility and applicability of the proposed fabrication method.Practical implicationsThe presented information can help limited budget companies and small educational institutions in electronics to fabricate microwave circuits at low costs. This is an excellent approach for students who want to learn how to make microwave frequency measurements and circuits without the need of expensive fabrication equipment and clean rooms.Originality/valueThe step‐by‐step fabrication method described in this paper allows fabricating different microwave components at low costs. The presentation of electrical models for each component completes the design‐fabrication cycle. As this information is gathered in a single source, it makes easier the incursion of new actors in the microwave field.

Authors: Nahar R.K. , Singh Vikram 
Published: May 2010

PurposeHigh‐dielectric thin films are considered as future dielectric for Si based advanced integrated circuit technology and also for the development of organic thin film transistors and micro sensors. The conventional dielectric SiO2 is grown by thermal oxidation of silicon whereas the HfO2 films are grown by both physical and chemical methods. Depending on film deposition technique, the film and interface characteristics are affected. The purpose of this paper is to investigate the effect of thermal annealing in oxygen and nitrogen ambient on the electrical properties of HfO2‐based metal oxide semiconductor (MOS) capacitor and evaluate thermal stability of the characteristics.Design/methodology/approachHfO2 films are deposited by rf sputtering and Al‐HfO2‐Si MOS capacitor fabricated. The electrical I‐V and C‐V characteristics are measured and the effect of temperature in the range of 25‐200°C is evaluated for films annealed in oxygen and nitrogen.FindingsIt is found that thermal annealing in nitrogen reduces oxide trap density and improves the temperature stability compared to the film annealed in oxygen for MOS devices. From the conductance characteristics Dit oxide trap density in the film is estimated to be 2.1×1011/cm2 for nitrogen and 3.23×1011/cm2 for oxygen, which indicates the role of nitrogen in reducing oxide traps. The thermal activation energy of electron traps is found to be about 0.19 eV for nitrogen and 0.58 eV for oxygen annealed films in the temperature range of 25‐150°C.Originality/valueThe paper examines and compares the role and effect of thermal annealing in nitrogen ambient and oxygen ambient on the electrical properties of sputtered HfO2 thin film for improved MOS device reliability.

Authors: Gupta Sanjeev K. , Azam A. , Akhtar J. 
Published: May 2010

PurposeThe purpose of this paper is to electrically examine the quality of thin thermally grown SiO2 with thickness variation, on Si‐face of 4H‐SiC <0001> (having 50 μm epitaxial layer) by current‐voltage (I‐V) and capacitance‐voltage (C‐V) methods.Design/methodology/approachMetal‐oxide‐silicon carbide (MOSiC) structures with varying oxide thickness have been fabricated on device grade 4H‐SiC substrate. Ni has been used for gate metal on thermally oxidized Si‐face and a composite layer of Ti‐Au has been used for Ohmic contact on the highly doped C‐face of the substrate. Each structure was diced and bonded on a TO‐8 header with a suitable wire bonding for further testing using in‐house developed LabVIEW‐based computer aided measurement setup.FindingsThe leakage current of fabricated structures shows an asymmetric behavior with the polarity of gate bias ( + V or −V at the anode). A strong relation of oxide thickness and temperature on effective barrier height at SiO2/4H‐SiC interface as well as on oxide charges have been established and reported in this paper.Originality/valueThe paper focuses on the development of 4H‐SiC based device technology in the fabrication of MOSiC‐based integrated structures.

Authors: Yang Jian‐hong , Wei Ying , Cai Xue‐yuan , Ran Jin‐zhi 
Published: May 2010

PurposeThe paper aims to investigate the influences of the tensile strain and the threading dislocations (TDs) in the germanium (Ge) epitaxial layer on the performance of the Ge vertical p‐i‐n photodetectors on Si substrate.Design/methodology/approachThe dark current, photo responsivity and time responsivity of detector were calculated using two‐dimensional drift‐diffusion device modeling and compared with experimental data.FindingsThe incorporation of the tensile strain and the reduction of the TDs in the Ge epilayer can increase the performance of the detector.Originality/valueAn optical design of detector is suggested with lower TD in the Ge buffer layer, which can exhibit superior performance.

Authors: Ramizy Asmiet , Aziz Wisam J. , Hassan Z. , Omar Khalid , Ibrahim K. 
Published: May 2010

PurposeThe purpose of this paper is to describe how fabricate solar cell based‐on porous silicon (PS) prepared by electrochemical etching process is fabricated and the effect of porosity layer on the solar cell performance is investigated.Design/methodology/approachThe techniques used include SiO2 thermal oxidation, ZnO/TiO2 sputtering deposition and PS prepared by electrochemical etching. Surface morphology and structural properties of porous Si were characterized by using scanning electron microscopy. Photoluminescence and Raman spectroscopy measurements were also performed at room temperature. Current‐voltage measurements of the fabricated solar cell were taken under 80 mW/cm2 illumination conditions. Optical reflectance was obtained by using optical reflectometer (Filmetrics‐F20).FindingsPore diameter and microstructure are dependent on anodization condition such as HF: ethanol concentration, duration time, temperature, and current density. On other hand, a much more homogeneous and uniform distribution of pores is obtained when compared with other wafer prepared with different electrolyte composition.Originality/valuePS is found to be an excellent anti‐reflection coating against incident light when it is compared with another anti‐reflection coating and exhibits good light‐trapping of a wide wavelength spectrum which produce high efficiency solar cells (11.23 per cent).

Authors: Clacher Iain 
Published: May 2010

PurposeThe purpose of this paper is to review the issues, difficulties, importance for public policy and current initiatives associated with developing a more comprehensive national accounting framework in relation to public and private sector investments in intangible assets.Design/methodology/approachThe paper analyses and evaluates the most salient statistics on intangible asset investments and the implications for public and private sector policy makers.FindingsThe UK economy has a high representation of firms and activities that invest in intangible assets that are not traditionally included in national accounts and that their exclusion has a significant impact on the UK's apparent growth and productivity performance.Originality/valueThe paper discusses a range of measurement and other difficulties in significantly developing a comprehensive national accounting framework that fully incorporates the impact of intangible asset investments upon national growth and productivity metrics.
Fair value accounting and intangible assets
Authors: Lhaopadchan Suntharee 
Published: May 2010

PurposeAdvocates of greater intangible asset reporting frequently make the criticism that the published financial statements of companies do not adequately reflect the value of intangible assets and hence provide potentially misleading information to the users of the financial statements. The purpose of this paper is to evaluate whether since the introduction of “fair value accounting,” particularly in respect of the treatment of acquired “goodwill” shown on consolidated balance sheets, these criticisms retain any validity. The paper investigates the extent to which it can be confidently asserted that the recognition of acquired goodwill and the post‐acquisition rules for recognizing any goodwill “impairment” has materially improved the information available to the users of financial statements and/or whether these developments have resulted largely in providing self‐interested managers with greater opportunities to engage in earnings and balance sheet manipulations that are of doubtful value to users.Design/methodology/approachThe paper critically reviews the rules and the intentions of accounting policy makers in relation to fair value acquisition accounting and evaluates the empirical evidence relating to corporate behavior in this area.FindingsDespite the presumed benefits associated with fair value accounting, it is shown that in practice managerial self‐interests and earnings management concerns appear to motivate many goodwill impairment decisions. However, as investors and analysts have always had the option to adjust, or indeed totally ignore, reported accounting numbers it is far less certain whether this reporting behavior actually misleads users or significantly reduces the information content (reliability and relevance) of the financial statements.Originality/valueThe paper provides an overview of the accounting treatment and reporting consequences associated with the introduction of fair value accounting in respect of acquired goodwill.

Authors: Bonsón Enrique , Cortijo Virginia , Escobar Tomas , Flores Francisco , Monreal Sergio 
Published: May 2010

PurposeThe purpose of this paper is to analyse the way in which the insurance industry is facing the renewal of its regulatory framework with respect to the levels of solvency that insurance entities should maintain. This paper also addresses how technological initiatives in general, and the eXtensible Business Reporting Language (XBRL), in particular, are making a key contribution to the process of adaptation to the new regulation.Design/methodology/approachThe paper analyses the particular advantages that the application of the XBRL standard can offer in this process, and highlight new lines for further research.FindingsAfter analysing the current situation of the insurance industry, the paper concludes that technological systems, such as XBRL, are necessary to support the consolidation of financial information, and to ensure the digital transparency of the insurer organisations that are engaged in this new regulatory challenge.Practical implicationsXBRL is a key resource in the European Common Reporting Project whose objective is the implementation of Basel II in the European Union. The implementation of Solvency II can benefit from this previous experience. Therefore, it suggest a proposal for action.Originality/valueThe affiliation of the authors to the insurance sector, the academia and the XBRL community contributes to create a complete view of the possibilities of this breaking project.
The dual role of the government: securities market regulation in China 1980‐2007
Authors: Ma Jingyun , Song Fengming , Yang Zhishu 
Published: May 2010

PurposeThe purpose of this paper is to examine the evolution of China's securities market regulation from 1980 to 2007 and the dual role of the government in this process.Design/methodology/approachWhen the government is simultaneously the owner and regulator of the securities market, the evolution of securities market regulation follows a path of compulsory institutional change. China's Government authorities have played a dual role in this process by acting both as the securities market regulator and the controlling owner of the stock exchanges. The paper uses the evolution of China's securities market regulation from 1980 to 2007 to illustrate this theoretical framework.FindingsUsing the case of China, this paper provides unique evidence of how securities regulation evolves in response to government direction and supervision if the government is both the owner and the regulator of the securities market.Originality/valueThe paper offers insight into issues of securities market regulation in China and other emerging markets.
