Query Technologies and Applications for Program Comprehension

Industrial software systems are large and complex, both in terms of the software entities and their relationships. Consequently, understanding how a software system works requires the ability to pose queries over the design-level entities of the system. Traditionally, this task has been supported by simple tools (e.g., grep) combined with the programmer's intuition and experience. Recently, however, specialized code query technologies have matured to the point where they can be used in industrial situations, providing more intelligent, timely, and efficient responses to developer queries. This working session aims to explore the state of the art in code query technologies, and discover new ways in which these technologies may be useful in program comprehension. The session brings together researchers and practitioners. We survey existing techniques and applications, trying to understand the strengths and weaknesses of the various approaches, and sketch out new frontiers that hold promise.

Sustainable investment in land in the Global South: What would it require from a coherence perspective? The case of Sierra Leone

Large scale acquisitions of land in the Global South have signifi-cantly increased since the millennium. It is often the case that foreign investors are involved in such acquisitions, which are commonly aimed at facilitating the export of commodities. These investments in land tend to transform conventional, rather small scale agricultural systems into large scale, industrial agricultural systems. While investment in ag-riculture in the Global South is much needed, large-scale investments in land often goes hand-in-hand with environmental and human rights re-lated challenges. As a consequence, lawyers need to address questions of sovereignty over natural resources (this paper focuses in particular on land resources), to peoples’ right to self-determination, to the responsi-bilities of the home and host states of the investors, including public-private relationships, and the role of international institutions who are involved, as well as relevant jurisprudence. This paper approaches these questions from the perspective of a theory on policy coherence for sus-tainable development.
