X-ray free electron lasers (XFELs) enable unprecedented new ways to study the electronic structure and dynamics of transition metal systems. L-edge absorption spectroscopy is a powerful technique for such studies and the feasibility of this method at XFELs for solutions and solids has been demonstrated. However, the required x-ray bandwidth is an order of magnitude narrower than that of self-amplified spontaneous emission (SASE), and additional monochromatization is needed. Here we compare L-edge x-ray absorption spectroscopy (XAS) of a prototypical transition metal system based on monochromatizing the SASE radiation of the linac coherent light source (LCLS) with a new technique based on self-seeding of LCLS. We demonstrate how L-edge XAS can be performed using the self-seeding scheme without the need of an additional beam line monochromator. We show how the spectral shape and pulse energy depend on the undulator setup and how this affects the x-ray spectroscopy measurements. (C) 2016 Optical Society of America
The PSM-leadership fit
(2013)
This article examines the use of performance information by public managers. It conceptualizes purposeful data use as a type of extra-role behaviour which requires additional effort on the part of the managers and which is not extrinsically rewarded. The article sheds light on one potential antecedent of performance information use – the motivation of the users. It argues that we can observe high levels of data use if managers driven by public service motivation (PSM) work under transformational leaders. Using a needs-supply perspective on supervisors and followers we suggest that there is a PSM-leadership fit which fosters the performance of this extra-role behaviour. The article is based on data from German local government and its findings contribute to the literatures on PSM as well as on performance management.
Nachdem die deutsche Ministerialverwaltung seit nunmehr zwei Jahrzehnten die Anwendung von Folgenabschätzungen weitestgehend ignoriert hat, beschloss das Bundeskabinett im April 2006 ein neues Instrument der better regulation einzuführen: das Standardkosten-Modell (SKM). Ziel der vorliegenden Studie ist es, die Wirksamkeit dieses Instruments zu untersuchen. Dazu wird ein qualitativer Bewertungsmaßstab deduktiv hergeleitet, operationalisiert und empirisch getestet. Das SKM wird demzufolge dann als wirksam erachtet, wenn es 1.) das Kräfteverhältnis zwischen Regulierungsbefürwortern und Regulierungsskeptikern zu Gunsten Letzterer verschiebt und 2.) mit der Einführung des Instruments die Weichen für einen Wandel der Regulierungskultur in der Ministerialverwaltung gestellt werden. Es zeigt sich, dass das Instrument gemäß Annahme 1 als Erfolg bewertet werden kann. Allerdings relativiert sich das Ergebnis, da Annahme 2 nicht erfüllt wird.
This article examines the use of performance information by public managers. It reviews literature on the impact of attitudes and social norm and puts forward a psychological-cognitive model based on the theory of planned behavior. The article finds support for this model emphasizing that performance data use is a goal-directed, reasoned action. Another critical result is that managers who consciously intend to use performance data also make sure that the data in their division are of good quality which, in turn, fosters information use. These findings indicate thatin addition to organizational routinescognitive factors are promising starting points for interventions to foster managers' data use. The article is based on survey data from German cities.

We present an excerpt of the document "Quantum Information Processing and Communication: Strategic report on current status, visions and goals for research in Europe", which has been recently published in electronic form at the website of FET (the Future and Emerging Technologies Unit of the Directorate General Information Society of the European Commission, http://www.cordis.lu/ist/fet/qipc-sr.htm). This document has been elaborated, following a former suggestion by FET, by a committee of QIPC scientists to provide input towards the European Commission for the preparation of the Seventh Framework Program. Besides being a document addressed to policy makers and funding agencies (both at the European and national level), the document contains a detailed scientific assessment of the state-of-the-art, main research goals, challenges, strengths, weaknesses, visions and perspectives of all the most relevant QIPC sub-fields, that we report here
The literature on performance information use explains how public managers deal with mainly quantitative data that are systematically collected and formally reported. This article argues that such a narrow understanding is incomplete, as it excludes all kinds of nonroutine performance information, including verbal, ad hoc, and qualitative feedback. To understand how responsive public managers are to performance feedback, alternative sources of performance information need to be taken into account. A literature review suggests considering two important sources of nonroutine feedback: organizational insiders and relevant external stakeholders. Using survey data from German local government, this article shows that public managers prefer to use nonroutine feedback over routine data from performance reports. Furthermore, a regression analysis indicates that different sources of performance information require different determinants to trigger their use. This finding is essential because it suggests that explanations of performance information use can covary with the information source studied.
