This paper looks at the implications of contemporary work in philosophy of science for nursing science. Early work on the nature of theories in nursing was strongly influenced by logical empiricism, and this influence remains even long after nurse scholars have come to reject logical empiricism as an adequate philosophy of science. Combined with the need to establish nursing as an autonomous profession, nursing theory's use of logical empiricism has led to serious conceptual problems. Philosophers of science have also rejected (...) many of the central tenets of logical empiricism, including its focus on the logical justification of theories and the idea that science is, or should be, unified. Instead, there has been an increasing focus on the practice of science, which in turn has led to a pluralist understanding of science that emphasizes the construction of scientific models that are appropriate for certain purposes or in certain contexts. I suggest that this approach to philosophy of science may provide better resources for nursing science. (shrink)

This study was designed to explore the concept of witnessed resuscitation. This was achieved through a serial approach to conceptually based research that systematically and incrementally developed understanding of the meaning of witnessed resuscitation in the context of emergency resuscitative care for adult victims of cardiorespiratory arrest. Theoretical investigation provided a strong conceptual foundation of existing knowledge and gave direction for further inquiry. Existential investigation comprised a hermeneuticphenomenological study to explore the phenomenon of lay presence during an adult cardiopulmonary resuscitation (...) attempt. Lived-experience material was subjected to thematic analysis and was revealing of five concepts that represented the essential nature of the lived experience. The concept of exposure emerged as the essence of this phenomenon. Research findings derived during theoretical and existential investigation were compared by adapting a method of template comparison. This process culminated in a synthesised conceptualisation of the meaning of witnessed resuscitation of a higher level of abstraction. Ongoing research is needed to determine whether this ‘state of the art’ conceptualisation of witnessed resuscitation holds its boundaries when applied to alternative phenomena, contexts and disciplines. Priority should be given to exploring the application of this concept in the context of patient and family-centred end-of-life care. (shrink)
