Technology Portfolios: A Metaphor For Usersʼ Technology Selections While Mobile?

Humans employ metaphors to understand, communicate and appropriate new, complex or perplexing aspects of their lives. This paper suggests that the rapid diffusion and widespread acceptance of mobile technologies have not been accompanied by a rich set of metaphors. Apt metaphors might help us to make sense of these technologies and the new practices that are emerging around them. The metaphor of a technology portfolio is proposed for users\u27 selections and deployment of technologies while mobile. Three case studies examining users’ technology selections while mobile are described. Observed practices can be understood and explained using the technology portfolio metaphor. The metaphor is particularly valuable given the changing nature of mobile technologies and the resulting difficulties in envisioning likely future needs and practice

Free/Libre/Open Source Software (Floss): Lessons for Intellectual Property Rights Management in a Knowledge-Based Economy

International audienceThe aim of this paper is to focus on the emerging situation in which open source software is nowadays produced not only by individual developers but in a growing proportion by firms that hire programmers for their own objectives of development in open source or for contributing to open source projects in the context of dedicated communities. As commercial firms it is important to analyze how and why they are capable of drawing benefits from such involvement and their connected activities. Moreover, we want to stress the different types of business model these firms rely on and the possible evolution they are likely to follow in the near future. We shown how Open Source principles provide an alternative way of thinking and managing intellectual property that do not come up against the same problems but needs a radical change in the way of drawing commercial benefits from knowledge development tasks. Then we analyze the growing involvement of commercial actors by setting up a typology of the different business models that can be observed in the OS landscape, how they correspond to the different strategies of industrial firms according to the main characteristics of their technical skills and market position. Finally, in a conclusive section we will draw the main lessons of the FLOSS experience for a possible enlargement of those principles of IPR management and business to other knowledge based commercial activities

The Interactive Lecture: Teaching and Learning Technologies for Large Classrooms

Conventional lectures in large classrooms are connected to fundamental didactic problems due to a lack of interactivity and feedback opportunities. In an interactive lecture each student is equipped with a light-weight, mobile device that can be used to interact with the lecturer during the lesson, thus creating an additional channel of communication. These devices support new teaching and learning paradigms such as participatory simulations. In this paper, we present our experiences with the usage of mobile devices in lectures. After discussing the didactic benefits of interactive lectures, we introduce the software toolkits used in our scenarios, we highlight selected tools like a quiz tool or a support tool for participatory simulation, and present major results from six studies we have conducted

Load flow studies on stand alone microgrid system in Ranau, Sabah

This paper presents the power flow or load flow analysis of Ranau microgrid, a standalone microgrid in the district of Ranau,West Coast Division of Sabah. Power flow for IEEE 9 bus also performed and analyzed. Power flow is define as an important tool involving numerical analysis applied to power system. Power flow uses simplified notation such as one line diagram and per-unit system focusing on voltages, voltage angles, real power and reactive power. To achieved that purpose, this research is done by analyzing the power flow analysis and calculation of all the elements in the microgrid such as generators, buses, loads, transformers, transmission lines using the Power Factory DIGSilent 14 software to calculate the power flow. After the analysis and calculations, the results were analysed and compared

Contemporary trends in banking

Over the recent decades, serious changes occurred in the economic, technological and social development, having reflected on banking operations. Changes ensuing today in the field of banking are of utmost significance. Banks are becoming multifunctional or in a certain fashion, are becoming genuine department stores of modern age. The globalization of financial and banking flows is realized by conceiving a new banking concept, due to bank adjustment to the new conditions of management. The traditional bank role has been evidently altered, hence banks in present-day conditions, apart from the standard banking operations, conduct a major number of unconventional banking operations, for instance, operations with securities, bank guarantees, mortgage services etc. Modern banks offer their clients a wide range of services, thus aggressively entering certain non-banking areas, by which they transform themselves into universal financial institutions. In the modern world banking system, we encounter banking and financial institutions which according to their activities and prevalence in their operations exceed national borders and enter the domain of international banking system. Nowadays, we can discuss about alleged planetary banking with engineering and re-engineering. It is characterized by its sophisticated, processing and globalized banking features. In short time interval, within the international banking system, several large-scope changes occurred, revolutionary in its essence, not solely in terms of banking, as well as in terms of the total monetary-financial-banking system. The determinants of such changes are as follows: altered conditions of fierce competition and fight to remain on the financial market; electronic and technological revolution which resulted in substitution of banking products with production of segmented banking process; and creation of new planetary banks which place their segmented banking processes on the so-called globalized supranational market
