    This paper reports the findings of a 1 year project which focussed solely on the potential of handheld computers for teacher professional development. The paper considers the fit between theory and practice, viewing the developing literature on mLearning as it might apply to teacher professional development, in the light of research evidence from project teachers using handheld computers. The teachers themselves used the analytical framework for teacher professional knowledge developed by Banks, Leach and Moon to consider their own experiences with the handheld computers. The study finds that handheld digital tools hold a number of pedagogic and pragmatic advantages over laptop or desktop computers for teachers, especially in rural communities; however, further technical development is required to fully orient the devices to classroom rather than office practices

    The real SAP® Business one cost : a case study of ERP adoption in an SME

    Get PDF
    This paper reports on a UK based service management Small and Medium-sized Enterprise (SME) that invested into SAP® Business One. The action research case study highlights the real cost and difficulties faced in moving to the one single SAP system and the process that was followed in order to identify third-party vendors that can integrate or customise SAP® Business One. This paper highlights the additional costs required to ensure a ‘fit-for-purpose’ solution to close the gap between strategic needs and the existing SAP Business One solution. The gap itself is illustrated by highlighting 10 key functionalities expected by the given service management SME. The actual implementation cost of the Enterprise Resource Planning (ERP) was found to be approximately double the initial SAP costs. The real costs involve time for, among other things, process reengineering, strategic decision making, software add-ons, staff-training, project-management and software maintenance

    The determinants of the quality of Sales-Marketing Interface in a Multinational Customer Brand Focused Company: The Latin American Branches

    Get PDF
    Customer evolution and changes in consumers, determine the fact that the quality of the interface between marketing and sales may represent a true competitive advantage for the firm. Building on multidimensional theoretical and empirical models developed in Europe and on social network analysis, the organizational interface between the marketing and sales departments of a multinational high-growth company with operations in Argentina, Uruguay and Paraguay is studied. Both, attitudinal and social network measures of information exchange are used to make operational the nature and quality of the interface and its impact on performance. Results show the existence of a positive relationship of formalization, joint planning, teamwork, trust and information transfer on interface quality, as well as a positive relationship between interface quality and business performance. We conclude that efficient design and organizational management of the exchange network are essential for the successful performance of consumer goods companies that seek to develop distinctive capabilities to adapt to markets that experience vertiginous change

    A 300-800MHz Tunable Filter and Linearized LNA applied in a Low-Noise Harmonic-Rejection RF-Sampling Receiver

    Get PDF
    A multiband flexible RF-sampling receiver aimed at software-defined radio is presented. The wideband RF sampling function is enabled by a recently proposed discrete-time mixing downconverter. This work exploits a voltage-sensing LNA preceded by a tunable LC pre-filter with one external coil to demonstrate an RF-sampling receiver with low noise figure (NF) and high harmonic rejection (HR). The second-order LC filter provides voltage pre-gain and attenuates the source noise aliasing, and it also improves the HR ratio of the sampling downconverter. The LNA consists of a simple amplifier topology built from inverters and resistors to improve the third-order nonlinearity via an enhanced voltage mirror technique. The RF-sampling receiver employs 8 times oversampling covering 300 to 800 MHz in two RF sub-bands. The chip is realized in 65 nm CMOS and the measured gain across the band is between 22 and 28 dB, while achieving a NF between 0.8 to 4.3 dB. The IIP2 varies between +38 and +49 dBm and the IIP3 between -14 dBm and -9 dBm, and the third and fifth order HR ratios are more than 60 dB. The LNA and downconverter consumes 6 mW, and the clock generator takes 12 mW at 800 MHz RF.\ud \u

    Technological Frames of Reference in Software Acquisition Decisions: Results of a Multiple Case Study

    Get PDF
    Packaged software has gained importance across organizations. While literature has studied the adoption and implementation of packaged software extensively, research on software acquisition has been limited. Especially, scholars have called for more research from a sociological point of view. Software acquisition projects are complex endeavors during which multiple stakeholders and perspectives interact. With this study, we strive to illustrate social interactions in software acquisition decisions through the theoretical lens of technological frames of reference. We conducted a multiple case study with 15 experts from IT, business, and procurement. We find evidence for distinct technological frames across departments that are combined during the software acquisition process, ultimately resulting in common understanding and consensus. Furthermore, we identify eight salient framing effects that facilitate this dynamic alignment of frames. Our results allow for an extension of technological frames of reference theory and support decision makers in optimizing their software acquisition decisions and processes

    Social Shaping of Enterprise System Acquisition and Development: The Influence of Reference Users in XiZi Holdings

    Get PDF
    In this research-in-progress paper, we present a preliminary model of how reference users shape enterprise systems (ES) acquisition and development based on the case study of Xizi Holdings, one of the largest private enterprises in China. Our model draws on the theoretical lens of the social shaping of technology in the context of streamlining complex packaged ES adoption. The model is built on stage-wise observations of the roles that reference users play across the ES acquisition and development process. Our preliminary model identifies three intermediary mechanisms (i.e. attaching, staging and shaping of technology) that are enabled by reference users in the process of negotiating ES acquisition and development. It contributes to the existing discourse in recent IS research on the expanding role of users in influencing the development of packaged enterprise systems and their acquisition
