By and large, we think (Strevens's [2005]) is a useful replyto our original critique (Fitelson and Waterman [2005]) of hisarticle on the Quine–Duhem (QD) problem (Strevens [2001]).But, we remain unsatisfied with several aspects of his reply(and his original article). Ultimately, we do not think he properlyaddresses our most important worries. In this brief rejoinder,we explain our remaining worries, and we issue a revised challengefor Strevens's approach to QD.
1 Strevens's ‘clarifications’
2 Strevens's new-and-improved ‘negligibility arguments’

Prior research on organizational routines in the ‘capabilities’ literature has either studied how new routines are created during an exploratory process of variation and selection or how existing routines are replicated during a phase of exploitation. Few studies have analyzed the life cycle of new routine creation and replication as an integrated process. In an in-depth case study of England’s Highways Agency, this paper shows that the creation and replication of a new routine across multiple sites involves four sequential steps: envisioning, experimenting, entrenching and enacting. We contribute to the capabilities research in two ways: first, by showing how different organizational levels, capabilities and logics (cognitive and behavioural) shape the development of new routines; and second, by identifying how distinct evolutionary cycles of variation and selective retention occur during each step in the process. In contrast with prior research on replication as an exact copy of a template or existing routine, our study focuses on the replication of an entirely new routine (based on novel principles) that is adapted to fit local operational conditions during its large-scale replication across multiple sites. We draw upon insights from adjacent ‘practice research’ and suggest how capabilities and practice studies may complement each other in future research on the evolution of routines.  相似文献

Digitization has resulted in great uncertainty for journalism, leading to disruption of business models, revenue streams, media distinctions, and production practices. This uncertainty has led to many articles, reports, blog posts, and general commentary discussing the future of both journalism and the skills required by journalists to succeed in this environment. This essay analyzes these discourses, focusing specifically on the nature of technology as the sole determiner of journalism’s future, with interventions aimed at journalism education and the structure of newswork. An idealized notion of the technologically adept journalist, ready to usher in digital stability, emerges as the object of these debates and, thanks in large part to the limited scope and ahistorical character of digital discourse, obscures more persistent, systemic critiques of technology and journalism.  相似文献

Pragmatic inclinations focused on health and wellness have begun to shape much of kinesiology. The wisdom of this trend is challenged as it tends to define leadership development. Chief among the problems with this trend is the loss of professional meaning. The inadequacy of pragmatism in establishing meaning for our professional activities is the central critique of this article. Michael Polanyi's understanding of the development of meaning, rooted in his theory of personal knowledge, is the basis for the critique. Polanyi's theory is expounded and then applied to the current pragmatic dispositions of our profession showing that such utilitarian approaches destroy meaning. A reorientation of the profession is then proposed toward a concept that has the capacity to capture a more genuine sense of professional meaning: play.  相似文献

This paper traces the evolution fitness testing from an athletic emphasis to one with a public health focus and examines the forces that brought about the change in an environment that was not totally receptive. An atmosphere for change was created during this era with the development of exercise physiology, exercise epidemiology, and measurement. The publication of a position paper of physical fitness by exercise scientists and the publication of state health-related fitness tests in the 1970s increased the pressure for change. Contemporary public health research clearly documents the positive role of physical activity, cardiorespiratory fitness, and body composition on health outcomes. During this era, exercise scientists developed valid laboratory and field tests of cardiorespiratory fitness and body composition that have become the standards of practice. Public health researchers have been able to provide valid fitness standards for health promotion. These validate the health-related approach.  相似文献
