MIS Quarterly: Management Information Systems | Year: 2010

Information systems strategy is of central importance to IS practice and research. Our extensive review of the literature suggests that the concept of IS strategy is a term that is used readily; however, it is also a term that is not fully understood. In this study, we follow a perspective paradigm based on the strategic management literature to define IS strategy as an organizational perspective on the investment in, deployment, use, and management of IS. Through a systematic literature search, we identify the following three conceptions of IS strategy employed implicitly in 48 articles published in leading IS journals that focus on the construct of IS strategy: (1) IS strategy as the use of IS to support business strategy; (2) IS strategy as the master plan of the IS function; and (3) IS strategy as the shared view of the IS role within the organization. We find the third conception best fits our defi-nition of IS strategy. As such, we consequently propose to operationalize IS strategy as the degree to which the organi-zation has a shared perspective to seek innovation through IS. Specifically, our proposed IS strategic typology suggests an organization's IS strategy falls into one of the two defined categories (i.e., IS innovator or IS conservative) or is simply undefined. We also develop measures for this new typology. We argue that the proposed instrument, which was cross-validated across both chief information officers and senior business executives, has the potential to serve as a diagnostic tool through which the organization can directly assess its IS strategy. We contend that our reconceptualization and operationalization of IS strategy provides theoretical and practical implications that advance the current level of understanding of IS strategy from extant studies within three predominant literature streams: strategic IS planning, IS/business strategic alignment, and competitive use of IS.

Since November 2011 the standard DIN 4709 stipulates performance tests for Micro-CHP units in Germany. In contrast to steady state measurements of the CHP unit itself, the test according to DIN 4709 includes the thermal storage tank as well as the internal control unit, and it is based on a 24 h test cycle following a specified thermal load profile. Hence, heat losses from the storage tank are as well taken into account as transient losses of the CHP unit. In addition, the control strategy for loading and unloading the storage tank affects the test results. The DIN 4709 test cycle has been applied at the test stand for Micro-CHP units at Reutlingen University, and results for the Micro-CHP unit WhisperGen and the EC Power units XRGI 15® and XRGI 20® are available. During the analysis a method has been developed to evaluate the results in case the test cycle does not end in a time slot between 24 and 24.5 h after the starting as demanded by DIN 4709. Since this method has been successfully applied to the test of various CHP units of different size and technology so far, it is suggested to incorporate it to DIN 4709 during the next revision of the standard. The performance numbers obtained reveal the differences in efficiencies measured at steady-state on the one hand and following the DIN 4709 test cycle on the other hand. While the deviations in electrical efficiencies are small, thermal efficiencies according to DIN 4709 fall below steady state data by 3-6 percentage points. This is attributed to transient thermal losses and heat losses from the storage tank, which are not included in steady state and separate testing of the CHP unit, only. © 2013 Elsevier Ltd. Source

Journal of Bionic Engineering | Year: 2011

The optimisation of earthquake resistance of high buildings by multi-tuned mass dampers was investigated using bionic algorithms. In bionic or evolutionary optimisation studies the properties of parents are crossed and mutated to produce a new generation with slightly different properties. The kids which best satisfy the object of the study, become the parents of the next generation. After a series of generations essential improvements of the object may be observed. Tuned mass dampers are widely used to reduce the impact of dynamic excitations on structures. A single mass system and multi-mass oscillators help to explain the mechanics of the dampers. To apply the bionic optimisation strategy to high buildings with passive tuned mass dampers subject to seismic loading a special beam element has been developed. In addition to the 6 degrees of freedom of a conventional beam element, it has 2 degrees of freedom for the displacements of the dampers. It allows for fast studies of many variants. As central result, efficient designs for damping systems along the height of an edifice are found. The impact on the structure may be reduced essentially by the use of such dampers designed to interact in an optimal way. © 2011 Jilin University. Source

SMEs and academic spin-offs play an important role in generating innovations but face resource and competency constraints that have implications for commercializing their technologies. In two in-depth case studies we analyze how patent-based investment funds (PBIFs), operating as innovation intermediaries, help overcome these constraints. In contrast to other patent intermediaries, PBIFs acquire patents and patentable inventions at an early stage of technology development when access to capital is particularly critical. They invest in the technological and legal advancement of their portfolio, which is mostly conducted in close interaction with the technology-providing SMEs and their original inventors. These PBIFs not only provide high added-value in the course of technology commercialization but also operate international networks to facilitate the commercialization of SMEs technologies at an international scale. Although PBIFs are a promising new agent in the heterogeneous field of innovation intermediaries, their commercialization results and the actual rate of returns are not yet well established. © 2011 Elsevier Ltd.

This article examines the impact of international power politics on trade liberalization and organized labour. Using regional and bilateral free trade agreements (FTAs) in the Asia-Pacific region as a case study, it discusses how China's economic rise and the ensuing interstate rivalry in the region have contributed to the proliferation of FTAs. In examining the politics of nation-states and organized labour in the Asia-Pacific with regard to FTAs, it identifies economic nationalism as a barrier to transnational labour solidarity. With a critical examination of alternative trade policies, this article explores alternative venues for global social justice and labour solidarity. © 2014 © 2014 Taylor & Francis. Source
