Program slice metrics and their potential role in DSL design, position paper

The advantages a DSL and the benefits its use potentially brings imply that informed decisions on the design of a domain specific language are of paramount importance for its use. We believe that the foundations of such decisions should be informed by analysis of data empirically collected from systems to highlight salient features that should then form the basis of a DSL. To support this theory, we describe an empirical study of a large OSS called Barcode, written in C, and from which we collected two well-known 'slice' based metrics. We analyzed multiple versions of the system and sliced its functions in three separate ways (i.e., input, output and global variables). The purpose of the study was to try and identify sensitivities and traits in those metrics that might inform features of a potential slice-based DSL. Results indicated that cohesion was adversely affected through the use of global variables and that appreciation of the role of function inputs and outputs can be revealed through slicing. The study presented is motivated primarily by the problems with current tools and interfaces experienced directly by the authors in extracting slicing data and the need to promote the benefits that analysis of slice data and slicing in general can offer.

Durkheim, ethnography and suicide: researching young male suicide in the transnational London Alevi-Kurdish community

This study of the unusually high incidence of young male suicides in the transnational Alevi-Kurdish community in London, demonstrates the benefits of combining a Durkheimian structural approach with a qualitatively driven ethnographic methodology. Examination of the life experiences of those who committed suicide is located within the underlying social organization of the transnational community in which the suicides occurred, enabling us to explore unanticipated events that render certain groups more at risk of committing suicide. Interviews with significant others facilitated a deeper understanding of the personal life paths of those who committed suicide. The suicide cases followed a particular assimilation trajectory that gradually positioned them in a “rainbow underclass”, an anomic social position leading to suicide. Despite the sensitivity of the subject, participants appreciated the opportunity to discuss their experience frankly and contribute towards a better understanding of the underlying causes in a desperate attempt to prevent further suicides.
