IS Success Awareness in Community-Oriented Design Science Research

Design efforts on innovative IS artifacts are increasingly taking place in agile, small, and specialized long-tail communities supported by academic research. Long-tail communities need to reflect and develop awareness for the success of community-specific IS (CIS) artifacts in their particular practice context in an ongoing manner. In community-oriented DSR, researchers participate as active community members contributing CIS success awareness with the help of CIS success models resulting from ongoing CIS evaluation. However, CIS success awareness is challenging to achieve compared to organizational IS due to diversity, dynamicity, informal structures and permeable boundaries. In this paper, we emphasize the benefits of ongoing CIS success awareness with the help of custom-tailored CIS success models in community-oriented DSR contexts. We demonstrate our approach in a longitudinal case study of designing and evaluating therapeutic tools in an aphasia community

The deep structure of a sea-floor hydrothermal deposit

Hydrothermal circulation at the crests of mid-ocean ridges plays an important role in transferring heat from the interior of the Earth1, 2, 3. A consequence of this hydrothermal circulation is the formation of metallic ore bodies known as volcanic-associated massive sulphide deposits. Such deposits, preserved on land, were important sources of copper for ancient civilizations and continue to provide a significant source of base metals (for example, copper and zinc)4, 5, 6. Here we present results from Ocean Drilling Program Leg 169, which drilled through a massive sulphide deposit on the northern Juan de Fuca spreading centre and penetrated the hydrothermal feeder zone through which the metal-rich fluids reached the sea floor. We found that the style of feeder-zone mineralization changes with depth in response to changes in the pore pressure of the hydrothermal fluids and discovered a stratified zone of high-grade copper-rich replacement mineralization below the massive sulphide deposit. This copper-rich zone represents a type of mineralization not previously observed below sea-floor deposits, and may provide new targets for land-based mineral exploration
