Most nutrient enrichment studies in aquatic systems have focused on autotrophic food webs in systems where primary producers dominate the resource base. We tested the heterotrophic response to long-term nutrient enrichment in a forested, headwater stream. Our study design consisted of 2 years of pretreatment data in a reference and treatment stream and 2(More)
We maintained elevated but moderate concentrations of nitrogen and phosphorus continuously for 2 years in a heavily shaded headwater stream and compared effects on stream periphyton with a reference stream. Both streams were sampled for 1 year before treatment. Some measures of periphyton biomass (ash-free dry mass and chlorophyll a) responded positively to(More)
Action research aims to generate and test action theories and thereby to develop and potentially emancipate practitioners. The precise nature of such action theories and what their generation and validation can potentially develop in practitioners are described. The possible costs of emancipatory action for nurses and a novel and potentially powerful(More)
Responses of detrital pathways to nutrients may differ fundamentally from pathways involving living plants: basal carbon resources can potentially decrease rather than increase with nutrient enrichment. Despite the potential for nutrients to accelerate heterotrophic processes and fluxes of detritus, few studies have examined detritus-nutrient dynamics at(More)
BACKGROUND A network of nine Clinical Development Units (Nursing) (CDU(N)) were recently created in the Western Sydney Area Health Service. These units are designed to develop patient-focused nursing practice through group process and action research, based on principles of transformational leadership. AIMS OF THE STUDY Although there is documented(More)
Despite the importance of peatlands, the algal ecology of peatlands and the periphyton communities which are abundant in these habitats are relatively understudied. We performed an in situ manipulation of pH in an intermediate fen in northern lower Michigan in order to examine how hydrogen ion concentrations structure an epiphytic algal community. Levels of(More)
It is argued that the structures and processes of traditional patterns of pre-registration nurse education in the United Kingdom led to an apparent and relative desensitization of student nurses to human need. The processes underpinning this apparent desensitization were those which promoted both a 'compartmentalization' of concepts for theory and concepts(More)
The common-sense construction of Buddhism is that of a general power for good; the less positive aspects of Buddhism's power, especially when reinforced by folklore and ancient superstition, is infrequently recognised. In this article we make explicit Buddhism's less positive power, particularly as it relates to the status of women and, by implication, its(More)
AIMS AND OBJECTIVES This purpose of this study was to describe the process of expertise acquisition in nephrology nursing practice. BACKGROUND It has been recognized for a number of decades that experts, compared with other practitioners in a number of professions and occupations, are the most knowledgeable and effective, in terms of both the quantity and(More)
AIM This paper elucidates the nature of metaphor and the conditions necessary to its use as an analytic device in qualitative research, and describes how the use of metaphor assisted in the analytic processes of a grounded theory study of nephrology nursing expertise. BACKGROUND The use of metaphor is pervasive in everyday thought, language and action. It(More)
