This article provides a spatial analysis of the conceptual framework of fluid dynamics during the nineteenth century, focusing on the transition from the Euler equation to the Navier–Stokes equation. A dynamic version of Peter Gärdenfors's theory of conceptual spaces is applied which distinguishes changes of five types: addition and deletion of special laws; change of metric; change in importance; change in separability; addition and deletion of dimensions. The case instantiates all types but the deletion of dimensions. We also provide a new view upon limiting case reduction at the conceptual level that clarifies the relation between the predecessor and successor conceptual framework. The nineteenth-century development of fluid dynamics is argued to be an instance of normal science development. 相似文献

This article picks up from William James's pragmatism and metaphysics of experience, as expressed in his “radical empiricism,” and further develops this Jamesian pragmatist approach to uncertainty and ignorance by connecting it to phenomenological thought. The Jamesian pragmatist approach avoids both a “crude naturalism” and an “absolutist rationalism,” and allows for identification of intimations of the sacred in both scientific and religious practices—which all, in their respective ways, try to make sense of a complex world. Analogous to religious practices, emotion and the metaphysics of experience play a central role in science, especially the emotion of wonder. Engaging in scientific or religious practices may create opportunities for individuals to realize that they are co‐creators of the world in partnership with God, in full awareness of uncertainty and ignorance and filled with the emotion of wonder. 相似文献

Abstract Rescue tasks under heavy strain may act as traumatic events creating stress reactions among the rescue workers. After a major rail accident the rescue workers were examined by questionnaire at 3 and 7 months postaccident using the General Health Questionnaire-28 (GHQ), Impact of Event Scale (IES) and a structured questionnaire made for the purpose. Eighteen percent of the 77 rescue workers who participated in the study had GHQ-case-score and 10% had IES-case-score at 7 months using the usual GHQ-cut-off (4/5) and a low IES-cut-off (19/20). For the case-scorers there was a tendency towards increased GHQ- and IES-scores from 3 to 7 months. Five (6%) had post-traumatic stress disorders (PTSD) of low to moderate severity at 7 months. 相似文献

Abstract We have recently developed and psychometrically evaluated an HIV-specific quality of life instrument. The new instrument is called the HIV Overview of Problems-Evaluation System (HOPES) which was adapted from an established cancer-specific quality of life instrument called the CARES. In this paper we review the psychometric properties of the HOPES, examine the quality of life impact of HIV infection in a cross-sectional evaluation of 318 patients using data from the HOPES and describe other work in progress or planned using the HOPES. 相似文献

This brief report describes a programmatic approach to health promotion that can help address the social determinants of mental-health and associated risky behaviours. Using a South African case example, we illustrate that while micro-system interventions help to strengthen individual resilience and immediate proximal protective influences, group system interventions can assist to promote health enhancing social identities and representations. We conclude that multi-level interventions that assume a systemic focus can strengthen community transformative efforts to address social determinants of mental and behavioural health. 相似文献
