[source] The Creation of a Vocational Sector in Swiss Higher Education: balancing trends of system differentiation and integrationEUROPEAN JOURNAL OF EDUCATION, Issue 4 2003Juan-Francisco Perellon The article discusses the establishment of a vocational sector in Swiss higher education as a complement to the existing two-tier system of cantonal Universities and federal Institutes of technology. The origins of this new player, its missions and organisational features are discussed. This overall discussion is placed into the context of changing landscape of Swiss higher education policy characterised by increasing pressures for geographical reorganisation of the higher education sector under the auspices of a more direct role of the federal government. The article makes two points. First, it argues that the creation of a vocational sector in Swiss higher education combines two contradictory trends. On the one hand, this new sector tends to provide differentiation at the system level, through the creation of a new, more marked-oriented sector of higher education. On the other hand, system differentiation at the system level is threatened by increased demands for greater inter-institutional cooperation and system integration, emanating principally from the federal level. Second, the article also argues that the distinction between ,academic/scientific' vs. ,vocational/professional' education generally referred to when studying the emergence of non-university sectors in higher education, is not pertinent for the analysis of the Swiss case. Two reasons are brought forward to sustain this argument. First, this distinction reinforces an artificial binary divide, no longer relevant to assess the evolution of higher education institutions placed in a context of academic and vocational drifts. Second, the ,academic' vs. ,professional' opposition does not take into consideration the political organisation of the country and how this impacts on policy making in higher education; a crucial element in the Swiss context. [source] An organisational approach to European integration: Outline of a complementary perspectiveEUROPEAN JOURNAL OF POLITICAL RESEARCH, Issue 2 2004Morten Egeberg Intergovernmentalists usually preclude any profound impact of European Union (EU) institutions and organisations. Institutionalists (other than rational-choice institutionalists), on the other hand, claim that EU institutions are able to shape and reshape individual actors' preferences and sense of belonging. Seen from an organisational perspective, however, institutionalists often fail to specify (and theorise) the organisational components that institutions may contain. This ,unpacking' of institutions is necessary in order to clarify the conditions under which transformation of actors and policy processes might occur. This article tries to illustrate what an organisational approach has to offer in fields like committee governance and Commission decision making. In addition, organisational theory provides a yardstick for assessing the degree of overall system integration. [source] A comprehensive techno-economic analysis method for power generation systems with CO2 captureINTERNATIONAL JOURNAL OF ENERGY RESEARCH, Issue 4 2010Gang Xu Abstract A new comprehensive techno-economic analysis method for power generation systems with CO2 capture is proposed in this paper. The correlative relationship between the efficiency penalty, investment increment, and CO2 avoidance cost is established. Through theoretical derivation, typical system analysis, and variation trends investigation, the mutual influence between technical and economic factors and their impacts on the CO2 avoidance cost are studied. At the same time, the important role that system integration plays in CO2 avoidance is investigated based on the analysis of a novel partial gasification CO2 recovery system. The results reveal that for the power generation systems with CO2 capture, the efficiency penalty not only affects the costs on fuel, but the incremental investment cost for CO2 capture (U.S.$,kW,1) as well. Consequently, it will have a decisive impact on the CO2 avoidance cost. Therefore, the added attention should be paid to improve the technical performance in order to reduce the efficiency penalty in energy system with CO2 capture and storage. Additionally, the system integration may not only decrease the efficiency penalty, but also simplify the system structure and keep the investment increment at a low level, and thereby it reduces the CO2 avoidance cost significantly. For example, for the novel partial gasification CO2 recovery system, owing to system integration, its efficiency can reach 42.2%, with 70% of CO2 capture, and its investment cost is only 87$,kW,1 higher than that of the reference IGCC system, thereby the CO2 avoidance cost is only 6.23$,t,1 CO2. The obtained results provide a comprehensive technical,economical analysis method for energy systems with CO2 capture useful for reducing the avoidance costs. Copyright © 2009 John Wiley & Sons, Ltd. [source] A survey in indexing and searching XML documentsJOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 6 2002Robert W.P. Luk XML holds the promise to yield (1) a more precise search by providing additional information in the elements, (2) a better integrated search of documents from heterogeneous sources, (3) a powerful search paradigm using structural as well as content specifications, and (4) data and information exchange to share resources and to support cooperative search. We survey several indexing techniques for XML documents, grouping them into flat-file, semistructured, and structured indexing paradigms. Searching techniques and supporting techniques for searching are reviewed, including full text search and multistage search. Because searching XML documents can be very flexible, various search result presentations are discussed, as well as database and information retrieval system integration and XML query languages. We also survey various retrieval models, examining how they would be used or extended for retrieving XML documents. To conclude the article, we discuss various open issues that XML poses with respect to information retrieval and database research. [source] 5.8 GHz orientation-specific extruded-fin heatsink antennas for 3D RF system integrationMICROWAVE AND OPTICAL TECHNOLOGY LETTERS, Issue 7 2008Lance Covert Abstract In high-power RF transmitter applications, the heatsink can be used as an antenna for improved antenna performance and increased integration. Extruded-fin heatsink antennas designed at 5.8 GHz are orientation-specific when the heatsink base replaces the patch of a patch antenna. In this case, the orientation of the fins with respect to the patch edges plays a significant role in the antenna performance and must be considered. The results show that the heatsink antenna using a lossy, low-cost FR4 substrate increases the bandwidth from 3.1 to 17.6% and radiation efficiency from 62 to 87% compared with the patch antenna on the same substrate. Also, the orientation has a significant effect on the directivity, gain, and radiation pattern. By combining two functions into one structure, the component count in a system is reduced and the antenna performance can be improved. © Wiley Periodicals, Inc.

Bramklev Abstract Globalization pressures have now caused significant changes in the way industrial enterprises are organized and how products are developed, manufactured and brought to market. In global enterprises, the handling, transportation and storage of parts, sub-assemblies and final products demand for an efficient and effective development of the product,package-system (PPS). The objective set in this paper is to present the development of a generic package development process that facilitates the establishment of integrated product and package development and also provides a more proactive and holistic approach to the development of new and innovative packages for the global market. In an extensive review of the package development literature and through five multiple case studies within the package manufacturing industry, results on the package development process are generated and, in this paper, presented and synthesized into an updated version of the package development process. The process consists of the phases package planning, package system development, package concept design, package design, production ramp-up, package system integration and package system production ramp-up. The package development model proposed here takes its starting point in the development of the package system, thus providing the holistic perspective needed for being truly generic. Being generic in the given context assures or at least facilitates the possibility to support the development of the new and innovative package systems and package designs needed in the product manufacturing industry to enhance competitiveness.

[source] The Impacts of Enterprise Resource Planning Systems on Accounting Practice , The Australian ExperienceAUSTRALIAN ACCOUNTING REVIEW, Issue 22 2000PETER BOOTH This paper reports on the enteqbrise resource planning (ERP) systems experiences of Australian companies. It examines the degree of information system integration and associated benefits that respondent companies believe they have achieved, and the impact of ERP systems on the adoption of new accounting practices. The results indicate that while ERP users report high levels of information integration for many functional areas, the pattern is similar to that of non- users. Also, ERP systems seem to perform better in transaction processing and ad hoc decision- support than in sophisticated decision-support and reporting. Finally, ERP systems were found to have little influence on the use of new accounting practices. [source] | ||||||||||
