Cloud-Services gelten als zukunftsträchtiges Konzept zur Bereitstellung von IT-Leistungen und verdrängen zunehmend klassische IT-Outsourcing-Modelle. Allerdings weichen noch viele Unternehmen auf traditionelle Bereitstellungskonzepte (z. B. Betrieb eines eigenen Rechenzentrums, Klassisches Outsourcing) aus. Ein Grund hierfür ist das fehlende Vertrauen in die „Cloud“. Der Kunde kann in der Regel die möglichen Risiken und das Sicherheitsniveau des Anbieters nicht beurteilen, da er meist auch keine direkte Einsicht in die Abläufe und Strukturen des Dienstleisters hat (Winkelmann, 2010).
Die weitere Verbreitung von Cloud-Diensten hängt stark davon ab, ob die Leistungsabnehmer ausreichend Vertrauen in die IT-Dienstleister, die technische Infrastruktur und das gesamte organisatorisch-rechtliche Umfeld (z.B. auch den jeweiligen Rechtsschutz, Anspruchs- und Klagemöglichkeiten) haben. Eine Möglichkeit, diese Situation im Sinne einer Entscheidungshilfe zu verbessern ist es, ein neutrales „Zertifikat für ITSicherheit von Cloud-Services“ zu nutzen. Im Rahmen der weiteren Vertrauensbildung in die „Cloud“ ist der unabhängigen Zertifizierung von Cloud-Services eine erhebliche Bedeutung beizumessen.
Dieses White-Paper beschreibt typische Kategorien von Cloud-Services, thematisiert die hohe Bedeutung des Vertrauens in die Cloud und geht auf Anforderungen an eine „vertrauenswürdige Zertifizierung von Cloud-Dienstleistungen“ (Trusted Cloud-Services) ein.
Abschließend wird ein praxisreifes Lösungsangebot zur Zertifizierung von Cloud-Diensten vorgestellt, welches die zuvor beschriebenen Anforderungen erfüllen kann.
Im Rahmen eines Forschungsaufenthaltes an der Universidad de Buenos Aires (UBA) wurde in Kooperation mit der Fakultät für Veterinärwissenschaften und dem Zentrum für Interdisziplinäre Wasserforschung (CETA) eine Befragung unter Studierenden und Mitarbeitenden (wissenschaftlichen und Verwaltungsmitarbeitern sowie Professoren) durchgeführt. Diese Befragung befasste sich inhaltlich mit Themen zur Einstellung argentinischer Konsumenten zu nachhaltigen und biologischen Lebensmitteln. Dabei spielte ebenfalls die Wahrnehmung dieser Lebensmittel anhand von Siegeln eine Rolle. Ferner wurden auch Fragen zum Bewusstsein für zertifizierte Produkte gestellt, das ein Präjudiz für ein spezifisches Einkaufsverhalten ist.
This policy brief investigates the costs of child poverty in the Balkans, including deprivation in terms of education, health, and social mobility. It then lays out the potential of social protection, most notably in terms of building resilence and fostering development. Set against recent case studies from around the world, including Cambodia and Uganda, the brief gives policy recommendations on various critical issues including transfer schemes, transformative measures, and (alternative) care for children with disabilities.
This policy brief is part of a wider research project entitled ‘Building the Economic Case for Investments in Social Protection’. The research aims at demonstrating the potential impacts of social protection on inclusive growth. The project is a collaborative effort between the Maastricht Graduate School of Governance at the University of Maastricht and United Nations University-MERIT, NL; the Global Development Institute at the University of Manchester, UK; the School of Social Science at the University of Makerere, Uganda; and the Expanding Social Protection Programme of the Ugandan Ministry of Gender, Labour and Social Development. This project is part of the research agenda of the Knowledge Platform Inclusive Development Policies and funded by the Ministry of Foreign Affairs of the Netherlands through the NWO-WOTRO programme.
Integrated solar water splitting devices that produce hydrogen without the use of power inverters operate outdoors and are hence exposed to varying weather conditions. As a result, they might sometimes work at non-optimal operation points below or above the maximum power point of the photovoltaic component, which would directly translate into efficiency losses. Up until now, however, no common parameter describing and quantifying this and other real-life operating related losses (e.g. spectral mismatch) exists in the community. Therefore, the annual-hydrogen-yield-climatic-response (AHYCR) ratio is introduced as a figure of merit to evaluate the outdoor performance of integrated solar water splitting devices. This value is defined as the ratio between the real annual hydrogen yield and the theoretical yield assuming the solar-to-hydrogen device efficiency at standard conditions. This parameter is derived for an exemplary system based on state-of-the-art AlGaAs//Si dual-junction solar cells and an anion exchange membrane electrolyzer using hourly resolved climate data from a location in southern California and from reanalysis data of Antarctica. This work will help to evaluate, compare and optimize the climatic response of solar water splitting devices in different climate zones.
This paper seeks to explore the framework within which the International Labour Office should promote a principled, practical approach to social security policy in the new millennium. Integration has to be built around a joint coherent policy vision and building such a policy vision requires debate. This paper is a product of a joint effort of members of the ILO Social Security Department and social security specialists working in the ILO field offices.
Using a life-cycle approach, we identify key gaps for social reform in Georgia. The reduction of informal work is the most pressing of these, since formal employment is the backbone of any robust and reliable social insurance scheme. At the same time, greater financial resources are required through taxation in order to enable systematic social reform in Georgia. Both interventions are needed in order to fill the gaps in the current social protection system, which include the limited scope of pension and health insurance, as well as the lack of permanent unemployment insurance and universal child benefits.
Against the background of Germany’s long experience with social protection, we outline the main principles of the German welfare state and present the design of three main social insurance branches (pensions, health and unemployment). Based on the mixed experience that has emerged in Germany, in particular due to path dependencies and political deadlock, we derive lessons that inform a clear and coherent vision for social reform in Georgia.
This study aims to highlight the significance of social protection as an autonomous strategy for migration policies and research. It focuses particularly on the German strategies for combating the causes of flight and migration. By managing migration flows, stabilizing societies and encouraging economic development, social protection can play an important role in reducing migration flows. At the same time, social protection can act as a stabilizer in the countries of origin and accelerate economic growth as well as supporting individual decisions to return to the countries of origin.
This paper documents the reversal of pension privatization and the reforms that took place in the 1990s and 2000s in Poland. The report analyses the political economy of different reform proposals, and the characteristics of the new pension system, including laws enacted, coverage, benefit adequacy, financing and contribution rates, governance and social security administration, social dialogue, positive impacts and other key issues of Poland’s pension system.
The short survey „Green IT 2009“ got a very pleasant feedback. The authors received 132 useful answers within only two weeks of survey (15th January until 31st January 2009). The electronic forms were sent to 1.000 companies in Germany and some neighbouring countries. The results show very clearly that the companies are already acting. Green IT has found its way into the companies in different ways and activities. But Green IT is known as a technical topic of IT management or building services engineering. The investments are made mostly in technical activities (energy saving hardware, virtualisation, cooling and more). From a business view the sourcing departments have to change their strategies and processes. The type and amount of IT investment decisions are not concerned by Green IT activities. The main targets of the companies are saving energy and costs followed by advancements in marketing and innovation.

Im Projekt wurden die Nachhaltigkeitspotentiale partizipativer landwirtschaftlicher Produktionskonzepte exemplarisch untersucht und der Versuch gemacht, deren Zufriedenheitspotential für Erzeuger und Bürger zu erfassen. Die landwirtschaftlichen Betriebe konnten dabei auf der Grundlage der Leitlinien der Sustainability Assessment of Food and Agriculture (SAFA) in den Dimensionen gute Unternehmensführung, ökologische Integrität, ökonomische Resilienz und soziales Wohlergehen bewertet werden. Die einzelnen Ergebnisse sind nach Dimensionen und korrespondierenden Indikatoren in diesem Working Paper beschrieben. Zudem konnten Handlungsempfehlungen auch dazu erarbeitet werden, wie Untersuchungen anhand der SAFA-Leitlinien erfolgreich durchgeführt werden können.
The Participation Act, introduced in the Netherlands in 2015, puts into practice the idea that every individual has to make a contribution in a participatory society. The Act includes aspects of income support, compulsory activities in return for benefits, and labour market reintegration. Drawing on 45 interviews, we provide insights into interactions between the individual financial and social situation, an individual’s position in society, and reintegration activities. The narratives show the fundamental need for individual freedom and societal meaning, recognition, and appreciation, as well as the complex circumstances in which social assistance recipients make decisions. Conflicts between those needs and the Act lead to the question of how personal and societal objectives can be reconciled.
