Language workbenches are environments for simplifying the creation and use of computer languages. The annual Language Workbench Challenge (LWC) was launched in 2011 to allow the many academic and ...industrial researchers in this area an opportunity to quantitatively and qualitatively compare their approaches. We first describe all four LWCs to date, before focussing on the approaches used, and results generated, during the third LWC. We give various empirical data for ten approaches from the third LWC. We present a generic feature model within which the approaches can be understood and contrasted. Finally, based on our experiences of the existing LWCs, we propose a number of benchmark problems for future LWCs.

This is the first comprehensive theoretical article on aesthetic emotions. Following Kant's definition, we propose that it is the first and foremost characteristic of aesthetic emotions to make a ...direct contribution to aesthetic evaluation/appreciation. Each aesthetic emotion is tuned to a special type of perceived aesthetic appeal and is predictive of the subjectively felt pleasure or displeasure and the liking or disliking associated with this type of appeal. Contrary to the negativity bias of classical emotion catalogues, emotion terms used for aesthetic evaluation purposes include far more positive than negative emotions. At the same time, many overall positive aesthetic emotions encompass negative or mixed emotional ingredients. Appraisals of intrinsic pleasantness, familiarity, and novelty are preeminently important for aesthetic emotions. Appraisals of goal relevance/conduciveness and coping potential are largely irrelevant from a pragmatic perspective, but in some cases highly relevant for cognitive and affective coping. Aesthetic emotions are typically sought and savored for their own sake, with subjectively felt intensity and/or emotional arousal being rewards in their own right. The expression component of aesthetic emotions includes laughter, tears, and facial and bodily movements, along with applause or booing and words of praise or blame. Aesthetic emotions entail motivational approach and avoidance tendencies, specifically, tendencies toward prolonged, repeated, or interrupted exposure and wanting to possess aesthetically pleasing objects. They are experienced across a broad range of experiential domains and not coextensive with art-elicited emotions.
Our theoretical model (Menninghaus et al., 2019) defines aesthetic emotions by reference to their role in aesthetic evaluation, and specifically as being predictive of aesthetic liking/disliking. ...Skov and Nadal (2020) dismiss the construct of "aesthetic emotions" as a "dated supposition" adopted from a "speculative" tradition and assert that there are no such emotions. Accordingly, they question all pieces of empirical evidence we referred to as supporting our model. In our response, we rebut these objections point by point and defend as well as expand the empirical evidence in support of our model.
