Convergence, the digital takeover of communication and information, produces a new kind of interchangeability and interconnectedness among different media forms. The rise of digital media results in: ♦ the coming together, in a single application or service, of information content from telephony, sound broadcasting, television, motion pictures, photography, printed text publishing, and electron...

The recent elucidation of etiologic agents of infantile diarrhea has markedly improved our understanding of the pathophysiology and epidemiology of acute nonbacterial gastroenteritis. In addition, the study of these agents has led to the formulation of potential strategies for the prevention and treatment of these infections. The agent of nonbacterial gastroenteritis in children which has recei...

For many years, nurses in international clinical and academic settings have voiced concern about horizontal violence among nurses and its consequences. However, no known framework exists to guide research on the topic to explain these consequences. This paper presents a conceptual model that was developed from four theories to illustrate how the quality and safety of patient care could be affec...

What cortical inputs are provided to motor control areas while they drive complex learned behaviors? We study this question in the nucleus interface of the nidopallium (NIf), which is required for normal birdsong production and provides the main source of auditory input to HVC, the driver of adult song. In juvenile and adult zebra finches, we find that spikes in NIf projection neurons precede v...

Technology and market changes introduce uncertainty and equivocality in the product development arena, and firms are considering various structural relationships to help them cope with these changes. Concurrent engineering (CE) is a mechanism that can reduce uncertainty and equivocality and improve an organization’s competitive capabilities. CE is typically manifested through concurrent work-fl...

This paper provides an introduction to the specification language Z from a logical perspective. The possibility of presenting Z in this way is a consequence of a number of joint publications on Z logic that Henson and Reeves have co-written since 1997. We provide an informal as well as formal introduction to Z logic and show how it may be used, and extended, to investigate issues such as equati...

Nearly a century and a half after the destruction of the institution of slavery, and a half-century past the dawn of the civil rights movement, social life in the United States continues to be characterized by significant racial stratification. Numerous indices of well-being—wages, unemployment rates, income and wealth levels, ability test scores, prison enrollment and crime victimization rates...

The equivalence of the random-oracle model and the idealcipher model has been studied in a long series of results. Holenstein, Künzler, and Tessaro (STOC, 2011) have recently completed the picture positively, assuming that, roughly speaking, equivalence is indifferentiability from each other. However, under the stronger notion of reset indifferentiability this picture changes significantly, as ...
