This paper considers street performance, or busking,focusing on differences between performance in thisenvironment compared with the standard concertsetting. First, in contrast with a set, known ticketprice, the price of street performance isendogenously determined. Second, busking generallyinvolves a joint product: music and charity, wherecharity is produced internally by the audience andhas as its principal input the price paid for music.We show that these facts call into question somegeneral conclusions of conventional public financemodels, which suggest that the major efficiency problemwith busking is its inability to preventfreeriding behavior, and that freeriding, while efficient at the individuallevel, is inefficient at the societal level. In contrast, we argue in thispaper that busking, with freeriding and all, is not unambiguously inferior toconcert hall performance in terms of efficiency. 相似文献

ABSTRACTThis case study describes two iterations of a Digital Humanities (DH) “Studio” course on scholarly text encoding as a model for a DH curriculum at a small liberal arts college. Designed to accompany a three-credit humanities course, the one-credit DH Studios are taught by library faculty. The paired courses share a final project—a digital edition of a short work of literature encoded in the Text Encoding Initiative. The DH Studio creates a methodology-focused environment for students to practice information and digital literacies. 相似文献

Providing access to relevant biomedical literature in a clinical setting has the potential to bridge a critical gap in evidence-based medicine. Here, our goal is specifically to provide relevant articles to clinicians to improve their decision-making in diagnosing, treating, and testing patients. To this end, the TREC 2014 Clinical Decision Support Track evaluated a system’s ability to retrieve relevant articles in one of three categories (Diagnosis, Treatment, Test) using an idealized form of a patient medical record. Over 100 submissions from over 25 participants were evaluated on 30 topics, resulting in over 37k relevance judgments. In this article, we provide an overview of the task, a survey of the information retrieval methods employed by the participants, an analysis of the results, and a discussion on the future directions for this challenging yet important task. 相似文献
