Stephen C. Kleene [7] introduced the notion of realisability for analysing the relation between intuitionism and the theory of recursive functions. In particular he was able to show that intuitionistic number theory is closed under a (weak) Church rule: If ∀x∃yA(x, y) is provable, then there is a recursive function f such that for every natural number n, A(n, f(n) ) is provable. Using this it w...

Kurt Weichselberger, one of the influential senior members of the imprecise probability community, passed away on February 7, 2016. Almost throughout his entire academic life the major focus of his research interest has been on the foundations of probability and statistics. The present article is a first attempt to trace back chronologically the development of Weichselberger’s work on interval ...

In this paper a description is provided of the history of what was to become the specialty of clinical neuropsychology as it occurred in New York City over a period extending from about 1930 to 1960. An effort will be made to demonstrate that the field of clinical neuropsychology was essentially founded in New York because of a number of historical forces that will be discussed. Beginning with ...

Kurt Lewin famously proclaimed, “There is nothing so practical as good theory”, signifying that a good theory lends itself to being applied in a variety of contexts. This paper uses the lens of Max Weber’s theory of bureaucracy to examine contemporary EGovernment related research and literature. Two major, prevailing themes emerge from this exercise. The first theme that emerges is that IT (inf...

Patients discharged from The Methodist Hospital, Houston, TX, are contacted post discharge and asked to assess the care provided; specific questions are focused on pain management. Responses to these questions were initially unfavorable: only approximately 72.4% of patients were completely satisfied. An interdisciplinary team was developed on an acute-care unit at the hospital to individualize ...

In his introduction, Pinna (2010) quoted one of Wertheimer’s observations: “I stand at the window and see a house, trees, sky. Theoretically I might say there were 327 brightnesses and nuances of color. Do I have ‘327’? No. I have sky, house, and trees.” This seems quite remarkable, for Max Wertheimer, together with Kurt Koffka and Wolfgang Koehler, was a pioneer of Gestalt Theory: perceptual o...

At schools of nursing nationwide, surging enrollments in the early 2000s necessitated changes in administrative structures and departmental organization. The authors describe a collaboration between faculty and administrators at their midwestern liberal arts college that aided a reorganization of the school of nursing. Kurt Lewin's 1951 change theory provided the framework for the restructuring...
