Strategic Information Planning – Insights from an Action Research Project in the Financial Services Industry

The core purpose of strategic information planning (SIP) lies in identifying future directions for investments in information technology, information systems and information supply that will assist an organisation to realise its business goals. SIP is a critical challenge and major concern to both academics and practitioners, in particular consultants. While the latter have proposed a number of formal methodologies and principles of good practice, these are normative recommendations that are hardly justified through theoretical insight. In fact, SIP is yet to be well understood theoretically and requires more empirical support. This motivated us to carry out an in depth case study on SIP in a financial service company. The study aimed at improving the SIP practices in place and was conducted in an action research-like manner. This research report at hand presents the results of the study. We firstly describe the enterprise, its situation and the SIP practices in place. We then reflect upon the SIP process, its contingencies and its outcome in light of the current academic literature. This leads us to a number of theoretically informed suggestions that concern the improvement of SIP as well as the direction of the resulting information strategy. These suggestions have already been debated with senior IT executives from the case enterprise. This debate helped to confirm some theoretical propositions from literature while other recommendations were not agreed upon by the practitioners. Our findings from the study are finally framed to give a fresh impetus to future research and perhaps challenge some current wisdom. <br

A Literature Overview on Strategic Information Systems Planning

Strategic Information Systems Planning (SISP) has been among the highest ranked issues on management agendas for many years. As such, SISP should be a major concern for researchers as well. However, SISP does not play that important of a role in the academic discussion, at least in Germany. Leading German textbooks on Information Management devote only small sections to strategy themes. Moreover, the recommendations given for conducting SISP in these textbooks are mainly normative and hardly take international research findings into account. Taking this as a motivation, we conducted a comprehensive literature review of German and Anglo-American information systems journals. Our objective was to understand more fully what we know about SISP through international research. On the flip side, our research aims at identifying fields that are in urgent need for closer academic investigation so that individual speculations and normative recommendations might still substitute for valid research insights. Overall, we found a considerable amount of research conducted in the field of SISP that we organised in five broad thematic fields: Strategic IT impact, approaches to SISP, information systems strategy, and strategic alignment. We give a short overview of research conducted so far and seminal publications available in the research fields. Moreover, based on a sub-sample of our literature base, we compute statistics which indicate the intensity of the academic discussion in the different thematic fields over time. Our statistics show that most attention has been paid to the competitive use of IT. The IS strategy in contrast has only been of limited interest, though it is central to any strategic considerations in IS. Our survey also suggests that German speaking researchers have devoted relatively few efforts to SISP in comparison to their Anglo-American colleagues

Probing IMF using nanodust measurements from inside Saturn's magnetosphere

We present a new concept of monitoring the interplanetary magnetic field (IMF) by using in situ measurements of nanodust stream particles in Saturn's magnetosphere. We show that the nanodust detection pattern obtained inside the magnetosphere resembles those observed in interplanetary space and is associated with the solar wind compression regions. Our dust dynamics model reproduces the observed nanodust dynamical properties as well as the detection pattern, suggesting that the ejected stream particles can reenter Saturn's magnetosphere at certain occasions due to the dynamical influence from the time‐varying IMF. This method provides information on the IMF direction and a rough estimation on the solar wind compression arrival time at Saturn. Such information can be useful for studies related to the solar wind‐magnetosphere interactions, especially when the solar wind parameters are not directly available. Key Points A new method to probe IMF with nanodust measurements inside the magnetosphere Under changing IMF, ejected nanoparticles can re‐enter Saturn‐s magnetosphere IMF direction and solar wind compression arrival time can be derivedPeer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/99078/1/grl50604.pd

On Two Models of the Light Pulse Delay in a Saturable Absorber

A comparative analysis of two approaches to description of the light modulation pulse delay in a saturable absorber is presented. According to the simplest model, the delay of the optical pulse is a result of distortion of its shape due to absorption self-modulation in the nonlinear medium. The second model of the effect, proposed at the beginning of our century, connects the pulse delay with the so-called "slow light" resulting from the group velocity reduction under conditions of the coherent population oscillations. It is shown that all the known experimental data on the light pulse delay in saturable absorbers can be comprehensively described in the framework of the simplest model of saturable absorber and do not require invoking the effect of coherent population oscillations with spectral hole-burning and anomalous modifications of the light group velocity. It is concluded that the effect of group velocity reduction under conditions of coherent population oscillations has not received so far any experimental confirmation, and the assertions about real observation of the "slow light" based on this mechanism are groundless.Comment: Regretfully, the journal version of the paper (in Optics and Spectroscopy) appeared to be strongly corrupted due to ignorant editing. In particular, "coherent population oscillations" (CPO) was replaced by "population coherent oscillations" (PCO), "bleaching" - by "clearing", and "bleachable absorber " - by "clearable absorber". Here we present original version of the pape

To systematize them, we combine the classic Sartorian approach to classification with the more recent insights on explanatory typologies. At the outset, we classify per genus et differentiam – distinguishing between the genus and the different species within it. By drawing on the technique of explanatory typologies to introduce a basic model of policy learning, we identify four major genera in the literature. We then generate variation within each cell by using rigorous concepts drawn from adult education research. Specifically, we conceptualize learning as control over the contents and goals of knowledge. By looking at learning through the lenses of knowledge utilization, we show that the basic model can be expanded to reveal sixteen different species. These types are all conceptually possible, but are not all empirically established in the literature. Up until now the scope conditions and connections among types have not been clarified. Our reconstruction of the field sheds light on mechanisms and relations associated with alternatives operationalizations of learning and the role of actors in the process of knowledge construction and utilization. By providing a comprehensive typology, we mitigate concept stretching problems and aim to lay the foundations for the systematic comparison across and within cases of policy learning.European Research Council, grant no 230267 on Analysis of Learning in Regulatory Governance, ALREG

Space science applications for conducting polymer particles: synthetic mimics for cosmic dust and micrometeorites

Over the last decade or so, a range of polypyrrole-based particles have been designed and evaluated for space science applications. This electrically conductive polymer enables such particles to efficiently acquire surface charge, which in turn allows their acceleration up to the hypervelocity regime (>1 km s(-1)) using a Van de Graaff accelerator. Either organic latex (e.g. polystyrene or poly(methyl methacrylate)) or various inorganic materials (such as silica, olivine or pyrrhotite) can be coated with polypyrrole; these core-shell particles are useful mimics for understanding the hypervelocity impact ionisation behaviour of micro-meteorites (a.k.a. cosmic dust). Impacts on metal targets at relatively low hypervelocities (10 km s(-1)) generate predominately atomic species, since many more chemical bonds are cleaved if the particles impinge with higher kinetic energy. Such fundamental studies are relevant to the calibration of the cosmic dust analyser (CDA) onboard the Cassini spacecraft, which was designed to determine the chemical composition of Saturn's dust rings. Inspired by volcanism observed for one of the Jupiter's moons (Io), polypyrrole-coated sulfur-rich latexes have also been designed to help space scientists understand ionisation spectra originating from sulfur-rich dust particles. Finally, relatively large (20 mu m diameter) polypyrrole-coated polystyrene latexes have proven to be useful for understanding the extent of thermal ablation of organic projectiles when fired at ultralow density aerogel targets at up to 6.1 km s(-1) using a Light Gas Gun. In this case, the sacrificial polypyrrole overlayer simply provides a sensitive spectroscopic signature (rather than a conductive overlayer), and the scientific findings have important implications for the detection of organic dust grains during the Stardust space mission

Information strategy-towards a comprehensive model of information strategy

Strategic information planning is an important topic in practice as well as in research. So far, work has mainly focused on the process of Strategic Information Planning (SIP) rather than on its result - the information strategy. But as long as the output of the planning process has not been well defined, all discussions on the process itself necessarily remain vague, too. Hence, research has been challenged with elaborating the concept of information strategy more precisely and in more detail. This paper discusses a comprehensive and comprehensible model of information strategy. The paper starts by analysing different views on information strategy from academic literature, the most advanced of which is perhaps the conceptualisation of information strategy as a system of plans. However, most interpretations found in the literature are implicit while the few explicit conceptualisations are not satisfactorily argued in terms of completeness, structure and rationale. The model proposed in this paper takes into account the interpretations of information strategy prevailing in the academic literature. It is based on a closer investigation of the domain of information strategies and distinguishes different subject matter of information processing. Our model helps to clarify and integrate the ongoing discussions devoted to information strategy as a functional and enterprise-wide strategy, as well as to strategic alignment and to the role of the CIO. It allows for an integration of traditionally separated interpretations on information strategy
