A systematic study of the adaptive maintenance process is undertaken. The research aims to better understand how developers adapt and migrate systems in response to such things as large API changes. The ultimate goal is to support the construction of automated methods and tools to support the adaptive maintenance process. The main case study involves an exhaustive manual investigation of a number of open source systems (e.g., KOffice, Extragear/graphics, and OpenGL) during a time when a large adaptive maintenance task was taking place. In each case the adaptive maintenance task involved a substantial API migration (e.g., Qt3 to Qt4) that took place over multiple years. Additionally, the systems were also undergoing other modifications (perfective and corrective) such as bug fixing and the addition of new features. The main goal of the study was to identify and distinguish the adaptive maintenance changes from the other types of changes. These adaptive maintenance commits are then analyzed to identify common characteristics and trends. The analysis examines the amount of change taking place for each commit, the vocabulary of the commit messages, the authorship of the changes, and the stereotype of modified methods. The data provides a point of reference for the study of these types of changes. This is also the first published in-depth and systematic examination of large adaptive maintenance tasks. The results show that adaptive maintenance tasks involve a relatively few number of large changes. There are also few developers involved in this task and they use a somewhat standard vocabulary in describing the associated commits. This information is they used as a means to automatically identify adaptive changes. An information retrieval technique, namely Latent Semantic Analysis, is used to retrieve relevant adaptive commits when querying the commits available in the version control system. The approach was found to have good accuracy. Our results show that the approach accurately retrieves relevant adaptive commits, with nearly 90% recall. Additionally, a means to uncover a set of traceability links between source code files and other artifacts resulting from adaptive maintenance tasks is developed. The validation results show highly precision predictions using TraceLab components.

Managing Organizational Change provides managers with an awareness of the issues involved in managing change, moving them beyond "one-best way" approaches and providing them with access to multiple perspectives that they can draw upon in order to enhance their success in producing organizational change. These multiple perspectives provide a theme for the text as well as a framework for the way each chapter outlines different options open to managers in helping them to identify, in a reflective way, the actions and choices open to them. Changing organizations is as messy as it is exhilarating, as frustrating as it is satisfying, as muddling-through and creative a process as it is a rational one. This book recognizes these tensions for those involved in managing organizational change. Rather than pretend that they do not exist it confronts them head on, identifying why they are there, how they can be managed and the limits they create for what the manager of organizational change can achieve.

The Working Group II contribution to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) provides a comprehensive assessment of the scientific literature relevant to climate change impacts, adaptation and vulnerability. The report recognizes the interactions of climate, ecosystems and biodiversity, and human societies, and integrates across the natural, ecological, social and economic sciences. It emphasizes how efforts in adaptation and in reducing greenhouse gas emissions can come together in a process called climate resilient development, which enables a liveable future for biodiversity and humankind. The IPCC is the leading body for assessing climate change science. IPCC reports are produced in comprehensive, objective and transparent ways, ensuring they reflect the full range of views in the scientific literature. Novel elements include focused topical assessments, and an atlas presenting observed climate change impacts and future risks from global to regional scales. Available as Open Access on Cambridge Core.

What has happened globally on the climate change issue? How have countries' positions differed over time, and why? How are problems and politics developing on an increasingly globalised planet, and can we find a solution? This book explores these questions and more, explaining the key underlying issues of the conflicts between international blocs. The negotiation history is systematically presented in five phases, demonstrating the evolution of decision-making. The book discusses the coalitions, actors and potential role of the judiciary, as well as human rights issues in addressing the climate change problem. It argues for a methodical solution through global law and constitutionalism, which could provide the quantum jump needed in addressing the problem of climate governance. This fascinating and accessible account will be a key resource for policymakers and NGOs, and also for researchers and graduate students in climate policy, geopolitics, climate change, environmental policy and law, and international relations.

This is an open access book. Histories we tell never emerge in a vacuum, and history as an academic discipline that studies the past is highly sensitive to the concerns of the present and the heated debates that can divide entire societies. But does the study of the past also have something to teach us about the future? Can history help us in coping with the planetary crisis we are now facing? By analyzing historical societies as complex adaptive systems, we contribute to contemporary thinking about societal-environmental interactions in policy and planning and consider how environmental and climatic changes, whether sudden high impact events or more subtle gradual changes, impacted human responses in the past. We ask how societal perceptions of such changes affect behavioral patterns and explanatory rationalities in premodernity, and whether a better historical understanding of these relationships can inform our response to contemporary problems of similar nature and magnitude, such as adapting to climate change.
