A Mediated Definite Delegation Model allowing for Certified Grid Job Submission

Grid computing infrastructures need to provide traceability and accounting of their users" activity and protection against misuse and privilege escalation. A central aspect of multi-user Grid job environments is the necessary delegation of privileges in the course of a job submission. With respect to these generic requirements this document describes an improved handling of multi-user Grid jobs in the ALICE ("A Large Ion Collider Experiment") Grid Services. A security analysis of the ALICE Grid job model is presented with derived security objectives, followed by a discussion of existing approaches of unrestricted delegation based on X.509 proxy certificates and the Grid middleware gLExec. Unrestricted delegation has severe security consequences and limitations, most importantly allowing for identity theft and forgery of delegated assignments. These limitations are discussed and formulated, both in general and with respect to an adoption in line with multi-user Grid jobs. Based on the architecture of the ALICE Grid Services, a new general model of mediated definite delegation is developed and formulated, allowing a broker to assign context-sensitive user privileges to agents. The model provides strong accountability and long- term traceability. A prototype implementation allowing for certified Grid jobs is presented including a potential interaction with gLExec. The achieved improvements regarding system security, malicious job exploitation, identity protection, and accountability are emphasized, followed by a discussion of non- repudiation in the face of malicious Grid jobs

Can regional community web portals become sustainable? : the Albany GateWAy : a case study

Asking the question can regional and community web portals become sustainable? demands a foray into many different disciplines. Sociology, education, business, strategic and knowledge management, organisational theory, relationship management and current technological trends and capabilities are some of the areas on which community projects, such us the development of communities on-line, are founded

Upsetting the offset : the political economy of carbon markets

xix, 363 p. : ill. ; 24 cm.Libro ElectrónicoUpsetting the Offset engages critically with the political economy of carbon markets. It presents a range of case studies and critiques from around the world, showing how the scam of carbon markets affects the lives of communities. But the book doesn’t stop there. It also presents a number of alternatives to carbon markets which enable communities to live in real low-carbon futures. ‘If you wondered whether capitalism could ever produce the perfect weapon of its own destruction, try this heady mix of carbon fuels, the trade in financial derivatives, and more than a dash of neo-colonialism, and boom! But this book is far from resigned to that fate. After examining the case against carbon trading… the book turns to alternatives, to hope, to sanity, and to the future.’ Professor Stefano Harney, Queen Mary, University of London, UKAlterar el desplazamiento involucra crítico con la política económica de los mercados de carbón. Se presenta una serie de estudios de caso y las críticas de todo el mundo, mostrando cómo la estafa de los mercados de carbono afecta a la vida de las comunidades. Pero el libro no se detiene allí. También presenta una serie de alternativas a los mercados de carbono que permitan a las comunidades a vivir en tiempo real de baja emisiones de carbono. "Si te has preguntado alguna vez si el capitalismo puede producir el arma perfecta de su propia destrucción, prueba esta embriagadora mezcla de combustibles de carbono, el comercio de los derivados financieros, y más de un toque de neo-colonialismo, y ¡bum! Pero este libro está muy lejos de resignarse a ese destino. Después de examinar el caso contra el comercio de carbono ... el libro se convierte en alternativas, a la esperanza, a la cordura, y para el futuro.Contributors xi Acknowledgments xix FOREWORDS The Business of Carbon is Different 1 Offsets Under Kyoto: A Dirty Deal for the South 2 Carbon Markets: A Fatal Illusion 5 INTRODUCTION 1 Upsetting the Offset: An Introduction 9 2 Neoliberalism and the Calculable World: The Rise of Carbon Trading 25 CASES 3 Double Jeopardy: Pursuing the Path of Carbon Offsets and Human Rights Abuses 41 4 How Sustainable are Small-Scale Biomass Factories?

Overcrowded as normal: governance, adaptation, and chronic capacity stress in the England and Wales prison system, 1979 to 2009

Why do public policy systems sustain chronic conditions despite general consensus that these conditions are detrimental to overall performance? The answer is because they are, in one way or another, sustainable. Systems find ways of sustaining manageable and acceptable equilibrium between demand for their services and their supply. Yet in doing so, they develop ways of coping with and normalizing situations of chronicness. This research is about chronic capacity stress (CCS) in a large and complex public policy system. CCS may be caused by excessive demand for services. It may also be caused by inadequate supply. Either way, it is a property of sustainable equilibrium between the two, and therefore must be understood in these dynamic terms rather than as just the product of one or the other. I examine overcrowding in the England and Wales prison system as an archetypal case of CCS. It starts with the assumption that the prison system should in theory be set up to deal with the demands made upon it. In doing so, it examines the way in which the system itself has coped with, normalized, and sustained crowding over the years. I have conducted in-depth interviewing with former ministers, top officials, governors, and other key actors, as well as extensive quantitative analysis covering three decades. I develop four inter-related themes as a part of a ‘problematique’ which explains why CCS is sustained: ambivalence towards rehabilitation, coping and crisis culture, benign resistance, and obsolescence and redundancy. Constrained autonomy of actors and their adaptive behaviours are key to understanding how the system sustains CCS, and how it is able to function despite CCS. Ultimately, I show how three groups of public policy theory – public choice, cultural theory, and governance - are vital aspects of an overall explanation, but that independently they are insufficient to explain why chronicness sustains, and therefore must be integrated into a more holistic, governance-style explanation. CCS can be seen as a function of governance dysfunction
