The evolutionary process and collaboration in supply chains
Authors: Cheng Hsiu‐Chun , Chen Mu‐Chen , Mao Chi‐Kuo 
Published: March 2010

PurposeThe primary aim of this paper is to investigate the evolutionary process and collaboration within Taiwan's cut‐flower supply chains. The paper also go on to discuss the enablement of supply chain coordination through information technology (IT) adoption and network effects, as well as performance improvements achieved by the introduction of the wholesale information sharing hotline (WISH) system.Design/methodology/approachThis paper examines the evolutionary process in Taiwan's cut‐flower supply chains from a macro‐study perspective, based upon primary data obtained from in‐depth interviews. The paper also applies multiple regression analyses from a micro‐study perspective, in order to gain insights into the evolution of market share within the supply chains, thereby facilitating the investigation of the effectiveness of the WISH system.FindingsThe results reveal that the auction houses are heavily dependent upon reliable sources of supply, and that in the earlier stages of the evolutionary process, they played a mediating role in the formulation of auction lines based upon retailer demand through the adoption of the e‐auction mechanism. Since then, the operational performance of the auction houses has been improved considerably, with horizontal coordination being supported by information sharing through the WISH system. The network effect is found to have a positive correlation with the number of participants within the system.Originality/valueThis paper focuses specifically on the evolutionary process of the cut‐flower supply chains in Taiwan, examining the simultaneous achievement of both vertical and horizontal collaboration through the advancement of IT.

Published: March 2010

PurposeThe purpose of this paper is to determine undergraduate students' information‐seeking behavior and their thought processes involved in, criteria applied to, and methods of, evaluating the results of their searches, in determining which information to apply to their research.Design/methodology/approachThe paper observed, recorded and analyzed the processes and sources used by undergraduate students when seeking information on a given topic.FindingsStudents did not use as many of the criteria necessary for evaluating sources for a research paper as the authors had hoped to observe; therefore, the students identified relatively few scholarly sources.Practical implicationsEven though many of the students had had a course‐integrated library instruction session before participating in the study, it did not seem to increase their evaluative skills, leading the authors to think that research skills need to be integrated in the curriculum in more meaningful ways by teaching faculty.Originality/valueThe paper raises awareness of the search strategies and criteria that undergraduate students use to find information for their research papers.

PurposeThe purpose of this paper is to introduce a novel research area involved in fast compute‐online and electronic design automation (EDA) realization, so‐called COMPOL project or COMPOL software tool online (www.compute‐online.com) that is applied to designs of radio frequency integrated circuits/monolithic microwave integrated circuits (RFIC/MMIC) passive components.Design/methodology/approachThis research work will present an interactive software package that has been fitted and verified by the results based on full‐wave full domain Lagrange differential (FDLD) method and experimental approach to realize EDA of RFIC RFIC/MMIC passive components. The developed web platform is based on browser/server pattern, by use of VisualStudio.NET and ASP.NET technologies.FindingsIts functionality may include analysis, synthesis, optimization, interpolation, and modeling of spiral inductors and coplanar waveguide (CPW) with any shape on any material substrate for microwave and wireless applications. Through the complete online processing of the inductors and CPW designs, it is approvable to expand to design applications of other passive components such as resistor (R), capacitor (C), transmission line and connector, etc.Originality/valueThis compute‐online algorithm is first developed by the use of the originally established numerical method – FDLD makes one case design possible to be done online in the time range of seconds.

Authors: Ruan A.W. , Liao Y.B. , Li P. , Li W.C. 
Published: March 2010

PurposeWith the growing system‐on‐a‐chip (SOC) design complexity, SOC verification has become a major congestion. In this context, efficient and reliable verification environment is requested for SOC design before it is committed to production. The purpose of this paper is to judge whether the hardware and or software (HW/SW) co‐verification environment can handle SOC verification and provide the necessary performance in terms of co‐verification speed and throughput, power and resource consumption, timing analysis, etc.Design/methodology/approachA finite‐impulse‐response filter is utilized as a device‐under‐test to compare pure SW simulation, Modelsim simulator in this case, and HW/SW co‐verification approaches to decide on whether the HW/SW co‐verification environment can do work or not. In addition, the performance of the HW/SW co‐verification environment is estimated based on specifications such as co‐verification speed and throughput, power and resource consumption, and timing analysis.FindingsFrom experiment results, conclusions can be drawn that the more complicated SOC is, the greater the potential speedup of the co‐verification approach over SW simulation is. However, the communication between SW and HW in HW/SW co‐verification system is a major congestion, which may offset the acceleration achieved by moving large computation from the SW to the HW side.Originality/valuePerformance estimation for the HW/SW co‐verification environment has been conducted in terms of co‐verification speed and throughput, power and resource consumption, timing analysis, etc.

Published: March 2010

PurposeThere are a lot of applications available for infrared focal plane array (IRFPA). Thus, advanced functions are required to support a wide range of IRFPAs applications. The purpose of this paper is to present a control circuit for a user reconfigurable 320×256 readout integrated circuit (ROIC) designed for IRFPA applications.Design/methodology/approachIn order to implement reconfigurable ROIC, several advanced functions can be realized by the control circuit such as global reset, capacitive transimpedance amplifier (CTIA) gain selectable, CTIA bandwidth selectable, random access opening (RAO), dynamic image transposition, selectable outputs, and adjustable power dissipation. These advanced functions can be implemented by loading corresponding control words into a 60‐bit control register. There are seven types of control words available with 14‐bit control words reserved for the realization of other functions in the future to control corresponding seven advanced functions.FindingsDesign and simulation of the control circuit based on CSMC 0.5 μm process technology have been conducted to confirm these functions. Based on these functions, wide scene dynamic range can be achieved, and the application of ROIC is more flexible.Originality/valueThis paper describes more functions such as CTIA bandwidth selectable, global reset, and also improved functions of RAO.

Authors: Wu Jun , Wang Luyu 
Published: March 2010

PurposeThe purpose of this paper is to present a broadband parallel coupled‐line quadrature coupler implemented with lumped‐elements.Design/methodology/approachThe even‐ and odd‐mode method is used to compute the proposed coupler, and the analysis and optimization are done using the computer‐aided design tools. A design example of a broadband tunable quadrature coupler is provided.FindingsThis novel structure is clearly increasing the conductor spacing and decreasing the whole structure size, at the same time, the bandwidth is much wider.Originality/valueThis paper shows how a parallel coupled‐line quadrature coupler with lumped‐elements has been analyzed and designed, and proposes a simple and convenient method to calculate this structure. Compared with the normal parallel coupled‐line structure, the conductor spacing of this coupler is increased effectively, while the structure size is decreased. In addition, because of the tunable embedded capacitors, the bandwidth becomes much wider – a broadband up to 77 percent is achieved.

Authors: Lv Rui , Qing Linbo , Yu Yanmei , He Xiaohai , Zeng Qiangyu 
Published: March 2010

PurposeThe first purpose of this paper is to propose a scalable video coding scheme providing flexibility in video transmission, especially under wireless environment. The second purpose is to analyze the problem of lengthening the key frame interval in distributed video coding (DVC), and propose an approach to improve the rate‐distortion (RD) performance of DVC for long group‐of‐frames (GOF) size.Design/methodology/approachIn the proposed scheme, a base layer is first obtained from an H.264 coder. When a DVC coder is then used to code the enhancement layer, information in processing the base layer is extracted and analyzed to make multiple side‐information available and reduce error accumulation for DVC coding, thus further improving the performance of the DVC coder.FindingsBy dividing video into base and enhancement layers, the combined video coding architecture enables a flexible video transmission. In addition, several methods are used to improve the RD performance in DVC coding. Simulation shows that the proposed scheme outperforms non‐scalable DVC for long GOF size.Originality/valuePrediction from the decoding loop in base layer encoder largely reduces enhancement layer spatial redundancy. Multiple side‐information provides better estimation for DVC reconstruction. Long prediction loop is more reliable because error accumulation is effectively compensated.

Published: March 2010

PurposeThe purpose of this paper is to present a wireless sensor network system which can monitor human physiological signals of heartbeat rate and body temperature.Design/methodology/approachWhen physiological activity occurs, signals are generated. By measuring these signals, human activity can be monitored. With the help of a new network module named Waseda Hibikino Module‐2, which can transmit not only data, but also based of physiological signals, a wireless sensor network is established.FindingsWhile measuring physiological signals, a stable system is required. From human body to the terminal in a hospital, data must be sent completely, especially for example the heartbeat rate. And a stable transmission protocol must be applied during this process of wireless transmission.Originality/valueThis technology represents a new real‐time monitoring system of human physiological signals. With single data processing, it can prevent different kind of situations before a bad status like a heart attack occurs.

Authors: Andrew Alex M. 
Published: March 2010

PurposeThe purpose of this paper is to review a variety of developments during the summer of 2009, with the most significant being an interview with James Lovelock in which he discusses dire predictions that appear in his latest book. Others refer to definitions and educational material on cybernetics. Comments are made on a debate about torture, on which cybernetics theory has been brought to bear. An appreciative comment on the early work of Vallée is noted, as is the sad passing of Barbara Vogl of the American Society for Cybernetics.Design/methodology/approachThe aim is to review developments on the internet, especially those of general cybernetic interest.FindingsThe main aim is to review significant items from ongoing discussions, sometimes with interpretation that is additional to the original material, especially in the torture context.Practical implicationsThe interview with Lovelock has important implications for management of the ecology.Originality/valueIt is hoped this is a valuable periodic review.
National workshop on technical services in law libraries: an overview
Authors: Anyaogu Uluocha 
Published: March 2010

PurposeThis paper aims to explore the need for training and retraining of law librarians and other information professionals on the critical art of technical services. That exploration becomes even more critical in view of the exponential growth of available legal information in primary, secondary and web sources and the attendant change in legal information processing and management. The topic was discussed in a Nigerian Institute of Advanced Legal Studies' (NIALS) workshop in June 2007.Design/methodology/approachAn exploratory research design was adopted. The method was to first examine the course objectives of the workshop to ensure that it is well packaged to empower and re‐equip law librarians and information professionals. The next approach was to discuss the NIALS as the apex Institute for research and advanced studies in law. Then, the general overview of the workshop was discussed.FindingsLaw libraries and law librarians are challenged to develop better retrieval tools that enable access to legal and other subject‐specific information needed by the library's critical public and clientele system – user community. This is being necessitated by the fact that computer and other electronic systems are now used in the provision of technical services such as the production of catalog cards, indexing and abstracting of legal materials, to mention but a few.Originality/valueThe paper's originality lies in its discussion that new law librarians and other information professionals often find it difficult to relate their academic library training to real‐life professionals practice situation, especially in the sophisticated discipline of law. Older professionals on the other hand need retraining to adapt to the new era of technology‐driven information handling methodologies.
Market orientation in universities
Authors: Hemsley‐Brown Jane , Oplatka Izhar 
Published: March 2010

PurposeThe paper's purpose is to test: whether there are significant differences between England and Israel, in terms of perceptions of market orientation (MO) in higher education (HE); which MO dimensions (student, competition, intra‐functional) indicate more positive attitudes and whether the differences are significant; and the reliability of the instrument for using a larger sample of respondents internationally.Design/methodology/approachA comparative (online) survey of 68 academics in England and Israel was conducted during the academic year 2007. The MO questionnaire used comprises 32 factor items rated on a six‐point scale, categorised using three headings: market (student‐customer) orientation; competitor orientation; and inter‐functional coordination.FindingsOverall, academics in both countries indicated that their HE institution is oriented towards meeting students' needs and desires, and cares for students' well‐being, teaching and learning. In addition, the respondents alluded to their contribution to internal marketing, i.e. to the promotion of their university through their own work tasks and performance.Research limitations/implicationsThe study was restricted to a comparison of only two universities, one in Israel and one in England, and the sample size is small.Practical implicationsThe meeting of student needs, and a student centred approach can be an institutional mission, as well as a government driven initiative imposed on universities through the introduction of a market.Originality/valueAs MO frequently underpins the development and implementation of successful organisation‐environment relationships, the current paper is a first attempt to trace the contextual determinants of this orientation by comparing its frequencies and elements in two different HE systems.
