The Emergence of Partnership Networks in the Enterprise Application Development Industry - A Global Corporation Perspective

Currently, dramatic changes are happening in the IS development industry. The incumbent system developers (hubs) are embracing partnerships with less well established companies (spokes), acting in specific niches. This paper seeks to establish a better understanding of the motives for this strategy. Relying on existing work on strategic alliance formation, it is argued that partnering is particularly attractive, if these small companies possess certain capabilities that are difficult to obtain through other arrangements than partnering. Again drawing on the literature, three categories of capabilities are identified: the capability to innovate within their niche, the capability to provide a specific functionality that can be integrated with the incumbents’ systems, and the capability to address novel markets. These factors are analyzed through a case study. The case represents a market leader in the global IS development industry, which fosters a network of smaller partner firms. The study reveals that temporal dynamics between the identified factors are playing a dominant role in these networks. A cyclical partnership model is developed that attempts to explain the life cycle of a partnership within such a network.

Wissenschaftliche und Religiöse Welterfassung. Ein Kommentar zu Martin Bubers Perspektive auf ein spannungsreiches Thema

Befindet sich die Religion auf dem Rückzug gegenüber der vordringenden Wissenschaft? Welche Theorien gibt es zur Verhältnisbestimmung von Wissenschaft und Religion und was ist ihre wirkliche Differenz? Martin Buber geht diesen Fragen in einem bis vor kurzem noch unveröffentlichten Zürcher Referat nach. Der Essay kommentiert die Bemühungen Bubers um eine Klärung dieser Verhältnisbestimmung und stellt sie in den Kontext der heute international geführten Diskussion über Wissenschaft und Religion.

Sideband-Ratio and Harmonic Response of Sub-Millimeter Wave Mixers measured with a Martin Puplett Interferometer

Heterodyne receivers at millimeter and submillimeter wavelength are widely used for radiometric spectral line observations for atmospheric remote sensing or radio astronomy. The quantitative analysis of such observations requires an accurate knowledge of the mixers's sideband ratio. In addition, its potential sensitivity to spurious harmonics needs to be well understood. In this paper, we discuss a measurement technique for these receiver characteristics, which is based on a scanning Martin Puplett Interferometer used in conjunction with a wide band digital autocorrelation spectrometer for the analysis of the intermediate frequency band. We present measurement results of different double sideband and sideband separating mixers, which were developed for the proposed 340GHz multi-beam limb sounder STEAMR.

Speech Understanding with a New Implant Technology: A Comparative Study with a New Nonskin Penetrating Baha System

Objective. To compare hearing and speech understanding between a new, nonskin penetrating Baha system (Baha Attract) to the current Baha system using a skin-penetrating abutment. Methods. Hearing and speech understanding were measured in 16 experienced Baha users. The transmission path via the abutment was compared to a simulated Baha Attract transmission path by attaching the implantable magnet to the abutment and then by adding a sample of artificial skin and the external parts of the Baha Attract system. Four different measurements were performed: bone conduction thresholds directly through the sound processor (BC Direct), aided sound field thresholds, aided speech understanding in quiet, and aided speech understanding in noise. Results. The simulated Baha Attract transmission path introduced an attenuation starting from approximately 5 dB at 1000 Hz, increasing to 20–25 dB above 6000 Hz. However, aided sound field threshold shows smaller differences and aided speech understanding in quiet and in noise does not differ significantly between the two transmission paths. Conclusion. The Baha Attract system transmission path introduces predominately high frequency attenuation. This attenuation can be partially compensated by adequate fitting of the speech processor. No significant decrease in speech understanding in either quiet or in noise was found.

Laura Kalauz & Martin Schicks CMMN SNS PRJCT

Aktuelle Inszenierungen denken den ästhetischen Rahmen, in dem sie sich ereignen, oftmals dezidiert mit. Sie machen ihn zum Thema, stellen ihn zur Disposition oder üben praxisimmanent Kritik am Kunstsystem, in dem sie operieren und von dem sie abhängig sind. Exemplarisch für diese Tendenz fokussiert dieser Aufsatz die 2011 im Rahmen von Freischwimmer entstandene Produktion CMMN SNS PRJCT von Laura Kalauz und Martin Schick. Es wird aufgezeigt, wie Kalauz und Schick einerseits mit den Mitteln des Theaters gesellschaftspolitische Themen in spielerischen Interaktionen gemeinsam mit dem Publikum aushandeln und andererseits das Aufführungsdispositiv sowie Rolle von Rezipienten und Produzenten stets aufs Neue zur Disposition stellen.

Long-Term Effects of the Treatment of Depressive Female Inpatients in a Naturalistic Study: Is Early Improvement a Valid Predictor of Outcome?

Objectives: To examine the predictive value of early improvement for short- and long-term outcome in the treatment of depressive female inpatients and to explore the influence of comorbid disorders (CD). Methods: Archival data of a naturalistic sample of 277 female inpatients diagnosed with a depressive disorder was analyzed assessing the BDI at baseline, after 20 days and 30 days, posttreatment, and after 3 to 6 months at follow-up. Early improvement, defined as a decrease in the BDI score of at least 30% after 20 and after 30 days, and CD were analyzed using binary logistic regression. Results: Both early improvement definitions were predictive of remission at posttreatment. Early improvement after 30 days showed a sustained treatment effect in the follow-up phase, whereas early improvement after 20 days failed to show a persistent effect regarding remission at follow-up. CD were not significantly related neither at posttreatment nor at follow-up. At no time point CD moderated the prediction by early improvement. Conclusions: We show that early improvement is a valid predictor for short-term remission and at follow-up in an inpatient setting. CD did not predict outcome. Further studies are needed to identify patient subgroups amenable to more tailored treatments.
