Many SaaS providers nowadays want to leverage the cloud’s capabilities also for their existing applications, for example, to enable sound scalability and cost-effectiveness. This thesis provides the approach CloudMIG that supports SaaS providers to migrate those applications to IaaS and PaaS-based cloud environments. CloudMIG consists of a step-by-step process and focuses on two core components. (1) Restrictions imposed by specific cloud environments (so-called cloud environment constraints (CECs)), such as a limited file system access or forbidden method calls, can be validated by an automatic conformance checking approach. (2) A cloud deployment option (CDO) determines which cloud environment, cloud resource types, deployment architecture, and runtime reconfiguration rules for exploiting a cloud’s elasticity should be used. The implied performance and costs can differ in orders of magnitude. CDOs can be automatically optimized with the help of our simulation-based genetic algorithm CDOXplorer. Extensive lab experiments and an experiment in an industrial context show CloudMIG’s applicability and the excellent performance of its two core components.
A culture of trust is usually claimed to have many public benefits--by lubricating markets, managing organizations, legitimating governments, and facilitating collective action. Any signs of its decline are, and should be, a matter of serious concern. Yet, In Praise of Skepticism recognizes that trust has two faces. Confidence in anti-vax theories has weakened herd immunity. Faith in Q-Anon conspiracy theories triggered insurrection. Disasters flow from gullible beliefs in fake Covid-19 cures, Madoff pyramid schemes, Russian claims of Ukrainian Nazis, and the Big Lie denying President Biden's legitimate election. Trustworthiness involves an informal social contract by which principals author...
Welcome to the European Conference on Software Architecture (ECSA), which is the premier European software engineering conference. ECSA provides researchers and practitioners with a platform to present and discuss the most recent, innovative, and significant findings and experiences in the field of software architecture research and practice. The fourth edition of ECSA was built upon a history of a successful series of European workshops on software architecture held from 2004 through 2006 and a series of European software architecture conferences from 2007 through 2009. The last ECSA was merged with the 8th Working IEEE/IFIP Conference on Software Architecture (WICSA). Apart from the tradit...
A fundamental challenge that management faces in the twenty-first century is how to exercise adequate control, i. e. how to guide and direct the behaviour of their subordinates. With increasing globalisation firms witness a cross-cultural impact too. Of particular interest is the question of whether to use the standardized form of control similar to the home base of firms or whether to adapt their control practices to the local specificities. Given the meagre state of the literature in management control with a cross-cultural emphasis, this study addresses a real world problem, namely the question whether management control practices are configured similarly or differently across cultures. R...
Using experimental surveys as a primary source, Kim and Kim compare a wide range of developed countries to assess the determinants of generalized social trust. With data from Belgium, France, Italy, Japan, Singapore, South Korea, the Netherlands, and the United States, Kim and Kim present a detailed picture of trust at the individual level, across different ethnic groups, and across different regions with economic and cultural distinctions. They focus on a range of concepts, including generalized trust and familism; causal relationships among cultural values, particularized trust, and institutional trust at the individual level; and relationships between culture, wealth, and governance at the macro-level. In doing so, they consolidate substantial quantitative data with rigorous theoretical analysis and advance our understanding of social trust and prosociality in general. A valuable resource for researchers and advanced students in political science, sociology, and social psychology around the world.
This book constitutes the proceedings of the 28th International Conference on Advanced Information Systems Engineering, CAiSE 2016, held in Ljubljana, Slovenia, in June 2016. The 35 papers presented in this volume were carefully reviewed and selected from 211 submissions. The program included the following paper sessions: Collaboration, Business Process Modeling. Innovation, Gamication, Mining and Business Process Performance, Requirements Engineering, Process Mining, Conceptual Modeling, Mining and Decision Support, Cloud and Services, Variability and Configuration, Open Source Software, and Business Process Management.
This book provides practical frameworks for anyone hoping to become a successful global leader, and outlines the challenges that international firms face when managing across cultures. It highlights the cognitive, affective, and behavioral actions leaders can take to understand the differences between foreign values and traditions, and how to develop a corporate environment where global leadership can thrive. Drawing on the latest research findings, interviews with executives, and the author’s own teaching and consulting experience, this book emphasizes the need to adopt a cultural intelligence that embraces flexibility, openness, curiosity, and empathy. It provides advice and guidance on how to develop universal people management skills and navigate language barriers to avoid cross-cultural miscommunication. This multi-disciplinary book is essential reading for students and researchers of international business and management, I/O psychology, and organizations hoping to interact effectively with employees and clients across borders.
Is democratic governance good for economic prosperity? Does it accelerate progress towards social welfare and human development? Does it generate a peace-dividend and reduce conflict at home? Within the international community, democracy and governance are widely advocated as intrinsically desirable goals. Nevertheless, alternative schools of thought dispute their consequences and the most effective strategy for achieving critical developmental objectives. This book argues that both liberal democracy and state capacity need to be strengthened to ensure effective development, within the constraints posed by structural conditions. Liberal democracy allows citizens to express their demands, hold public officials to account and rid themselves of ineffective leaders. Yet rising public demands that cannot be met by the state generate disillusionment with incumbent officeholders, the regime, or ultimately the promise of liberal democracy ideals. Thus governance capacity also plays a vital role in advancing human security, enabling states to respond effectively to citizen's demands.
A new, quantitative architecture simulation approach to software design that circumvents costly testing cycles by modeling quality of service in early design states. Too often, software designers lack an understanding of the effect of design decisions on such quality attributes as performance and reliability. This necessitates costly trial-and-error testing cycles, delaying or complicating rollout. This book presents a new, quantitative architecture simulation approach to software design, which allows software engineers to model quality of service in early design stages. It presents the first simulator for software architectures, Palladio, and shows students and professionals how to model re...
