Specific Yield as Determined by Type‐Curve Analysis of Aquifer‐Test Data

AbstractType‐curve analysis of water‐table aquifer pumping‐test data has often resulted in values of specific yield that are unrealistically low when compared with values obtained by volume‐balance calculations. It has been suggested that such values are the result of inadequate representation of drainage processes in the unsaturated zone. The commonly used analytical solution developed by Neuman for a homogeneous, water‐table aquifer assumes that the drainage of pores in the zone above the water table due to lowering of the water table occurs instantaneously. Published pumping‐test data from three relatively homogeneous, unconsolidated, granular aquifers with significantly different hydraulic conductivities are used to show that type‐curve analysis based on the Neuman model will result in estimates of specific yield that agree with volume‐balance calculations, provided that established procedures are followed. These involve the use of composite plots of drawdown observed at more than one location and inclusion of effects of partial penetration. Noninstantaneous drainage of pores in the unsaturated zone accounts for the finding that both type‐curve analysis and volume‐balance calculations yield values of specific yield that are slightly less than those obtained from laboratory column‐drainage experiments. It may also account for a slight underestimation of vertical hydraulic conductivity as obtained by type‐curve analysis.

Role analysis of the advanced practice nurse using the Neuman Health Care Systems Model as a framework.

The role of the advanced practitioner of nursing is perceived and operationalized differently from practice setting to practice setting. These differences should compel practitioners to analyze and differentiate role expectations within specific practice situations. The Neuman Health Care Systems Model provides a systematic framework for role analysis, development, enactment, and evaluation. The analysis should serve to decrease role stress, strain, and ambiguity while ultimately increasing role implementation success. The purposes of this article are: (a) to describe the general systems theory that is the basis of the Neuman model, (b) to describe the Neuman Health Care Systems Model to provide a basis for role analysis, and (c) to provide a structure for role analysis of the CNS. The benefit of a systematic microanalysis of the role of the CNS will be to develop a template to be used in the analysis of a particular position in the real world.

Adapting the Neuman systems model for family nursing.

Family nursing is in the early stages of development, and there is often difficulty in translating nursing conceptual frameworks into terms that are less abstract and more readily usable in the family practice arena. Yet the conversion of abstract ideas to concrete descriptions is necessary if nursing theory-based practice is to expand. This article describes the client system known as family within the Neuman systems model. Based on clinical data and the experience of nurses using the Neuman model in practice, a description of the family as client is developed. The five variables of Neuman's model are identified and the terms used in describing the family system are clarified. A rationale for the application is also presented.

The Betty Neuman Systems Model applied to practice: a client with multiple sclerosis

The importance of nursing theories and models for the growth and development of the profession of nursing is widely acknowledged. The variety of nursing phenomena and situations demands some flexibility in the choice of specific conceptualizations to be used. This paper demonstrates the goodness of fit of the Betty Neuman Systems Model to the care of clients with multiple sclerosis. An adapted assessment tool, based on Neuman's tool, but more useful in the acute care medical setting, is used to gather data related to a woman with recently diagnosed multiple sclerosis. A nursing care plan illustrating the use of Neuman's model is generated, implemented and evaluated. The Neuman Model is demonstrated to be useful and effective in the implementation of the nursing process in this case.

A Comparative Analysis of Neuman's Model Using the Individual and Family as the Units of Care

AbstractThis paper identifies the similarities and differences between nursing an individual as client and nursing a family as client when one uses the Betty Neuman systems model as a guide to practice. Several factors contribute to the decision to initiate an individual‐ or a family‐centered approach. Within the context of the Neuman systems model, a clinical situation illustrates several characteristics that highlight features of the two approaches.
