There is a sizeable group of self-described Christian companies which have declared their belief in the successful merging of biblical principles with business activities. As these companies have become more visible, an increasing number of anecdotal newspaper and magazine articles about these companies have appeared. Surprisingly, no rigorous research has been conducted prior to our recent study. This article provides national estimates of the size and predominant characteristics of self-identified Christian companies. In addition, the study investigated the types of relationships (...) these companies maintained with their employees, customers, communities, and suppliers. (shrink)

Finding an appropriate place for STS within the American science and engineering curriculum has never been easy. Convincing science, engineering, and medical students, and their professors, to pay serious attention to the broader context of their respective professions seems to require a sustained dialogue across conventional disciplinary boundaries. Otherwise, STS ends up talking mostly to itself and its critics rather than to its most important audience, students (at all levels) and the general public (especially museum visitors). This essay considers a (...) number of historical and present-day examples to argue that the founding vision of STS as a collaborative enterprise still offers some valuable lessons about how best to reach that audience.

Coalitional games raise a number of important questions from the point of view of computer science, key among them being how to represent such games compactly, and how to efficiently compute solution concepts assuming such representations. Marginal contribution nets , introduced by Ieong and Shoham, are one of the simplest and most influential representation schemes for coalitional games. MC-nets are a rulebased formalism, in which rules take the form pattern → value, where “pattern ” is a Boolean condition over agents, (...) and “value ” is a numeric value. Ieong and Shoham showed that, for a class of what we will call “basic” MC-nets, where patterns are constrained to be a conjunction of literals, marginal contribution nets permit the easy computation of solution concepts such as the Shapley value. However, there are very natural classes of coalitional games that require an exponential number of such basic MC-net rules. We present read-once MC-nets, a new class of MC-nets that is provably more compact than basic MC-nets, while retaining the attractive computational properties of basic MC-nets. We show how the techniques we develop for read-once MC-nets can be applied to other domains, in particular, computing solution concepts in network flow games on series-parallel networks. (shrink)

This comprehensive volume offers a wide-ranging perspective on the stories that art music has told since the start of the 20th century. Contributors challenge the broadly held opinion that the loss of tonality in some music after 1900 also meant the loss of narrative in that music. To the contrary, the editors and essayists in this book demonstrate how experiments in approaching narrative in other media, such as fiction and cinema, suggested fresh possibilities for musical narrative, which composers were quick (...) to exploit. The new conceptions of time, narrative voice, plot, and character that accompanied these experiments also had a significant impact on contemporary music. The repertoire explored in the collection ranges across a wide variety of genres and includes composers from Charles Ives and the Pet Shop Boys to Thomas Adès and Dmitri Shostakovich. (shrink)

In team-based tasks, successful communication and mutual understanding are essential to facilitate team coordination and performance. It is well-established that an important component of human conversation is the maintenance of common ground. Maintaining common ground has a number of associated processes in which conversational participants engage. Many of these processes are lacking in current synthetic teammates, and it is unknown to what extent this lack of capabilities affects their ability to contribute during team-based tasks. We focused our research on how (...) teams package information within a conversation, by which we mean specifically whether information is explicitly mentioned or implied, and how multiple pieces of information are ordered both within single communications and across multiple communications. We re-analyzed data collected from a simulated remotely-piloted aerial system task in which team members had to specify speed, altitude, and radius restrictions. The data came from three experiments: the “speech” experiment, the “text” experiment, and the “evaluation” experiment. We asked first whether teams settled on a specific routine for communicating the speed, altitude, and radius restrictions, and whether this process was different if the teams communicated in speech compared to text. We then asked how receiving special communication instructions in the evaluation experiment impacted the way the human teammates package information. We found that teams communicating in either speech or text tended to use a particular order for mentioning the speed, altitude, and radius. Different teams also chose different orders from one another. The teams in the evaluation experiment, however, showed unnaturally little variability in their information ordering and were also more likely to explicitly mention all restrictions even when they did not apply. Teams in the speech and text experiments were more likely to leave unnecessary restrictions unmentioned, and were also more likely to convey the restrictions across multiple communications. The option to converge on different packaging routines may have contributed to improved performance in the text experiment compared some of the conditions in the evaluation experiment. (shrink)
