Abstract

Purpose

This essay was written as a university assignment for an expert dementia practice module as part of the Masters in Applied Professional Practice. This paper aims to provide a critical discussion of the recognition and management of delirium superimposed on dementia.

Design/methodology/approach

The findings of this paper showed that the recognition of delirium superimposed of dementia is not well recognized, but early intervention and management can result in preferential outcomes. This requires the use of appropriate recognition tools and for all health-care staff to have specific training within this area.

Findings

Education is imperative to improving delirium recognition.

Research limitations/implications

Education is imperative to improving awareness.

Practical implications

The research implications of this paper demonstrate that appropriate training and education of health-care staff is imperative for the timely recognition of delirium and the improvement of care.

Originality/value

This paper was undertaken as an assignment for the University of Highlands and Islands.

Abstract

With the discovery of oil on Alaska's North Slope, the continued issues regarding the Alaska Native Land Claims Settlement Act, the oil spill of the Exxon Valdez in the Prince William Sound, the controversy over oil exploration in the Arctic National Wildlife Refuge, and the recent announcement by the United States Geological Survey that the Arctic will be the focal point for global change studies, Alaska, once known as “Seward's Follie” and a place that should be given back to Russia, continues to be in the forefront of national and international news.

Abstract

Purpose

The purpose of this mixed methods study is to define the core components of a system‐wide, acute care program designed to meet the needs of older adults.

Design/methodology/approach

Concept mapping methodology (multidimensional scaling and cluster analysis) was used to obtain data describing the core components of a geriatric acute care model. The input of 306 “stakeholders” (clinicians, administrators, consumers, educators, and researchers) was obtained through a world wide web interface, supplemented with consumer interviews.

Findings

The findings yielded eight clusters describing components of a geriatric acute care program: guiding principles, leadership, organizational structures, physical environment, patient‐ and family‐centered approaches, aging‐sensitive practices, geriatric staff competence, and interdisciplinary resources and processes. A total of 113 items that describe dimensions of quality were identified with these clusters.

Practical implications

The clusters and dimensions provide a framework for a hospital to use to plan, implement, and evaluate an acute care model for older adults.

Originality/value

There is not a common understanding of what constitutes a comprehensive set of resources, programs, and activities to address the needs of hospitalized older adults and their families and the staff who serve them. Concept mapping was an effective method of engaging the perspectives of various stakeholders in creating a framework to address these needs, as well as useful in illuminating areas for future research.

Abstract

Advanced laser micromachining techniques for a TFT‐LCD (thin film transistor‐liquid crystal display) module have been developed to repair various kinds of defects such as shorts, opens, and degraded TFTs. They have also been designed to analyse failures in the TFT‐LCD. The techniques are as follows: (i) The technique of zapping the excess metal: to repair short defects and/or to isolate the TFT being tested from the adjacent TFTs. This uses a pulse Xe or a Q‐switched YAG laser. (ii) Zapping, followed by the metal deposition technique: to repair open defects and/or to form electrical testing electrodes. This uses a Q‐switched YLF and an Ar ion laser. (iii) The technique of micro‐welding two metal lines separated by an insulating layer: to repair open defects. This uses a Q‐switched YAG laser. (iv) A separation technique utilised on a TFT‐LCD panel adhered with epoxy resin. This uses a pulse Excimer laser. (v) A micro‐annealing technique for a degraded TFT: to recover the TFT characteristics. This uses a Q‐switched YAG laser. Through the study described above, the authors have confirmed that these techniques are highly effective for obtaining TFT‐LCD modules without defects. The yield of TFT‐LCD modules may therefore be expected to improve.

Abstract

Purpose

The purpose of this paper is to study the effects of surface mass transfer on the steady mixed convection flow from a vertical stretching sheet in a parallel free stream with variable wall temperature and concentration.

Design/methodology/approach

An implicit finite difference scheme in combination with the quasilinearisation technique is employed to obtain non‐similar solutions of the governing boundary layer equations for momentum, temperature and concentration fields.

Findings

The numerical results are reported here to display the effects of mixed convection parameter, ratio of buoyancy forces, surface mass transfer (suction and injection), the ratio of free stream velocity to the composite reference velocity, Prandtl number and Schmidt number on velocity, temperature and concentration profiles as well as on skin friction, Nusselt number and Sherwood number.

Research limitations/implications

Thermophysical properties of the fluid in the flow model are assumed to be constant except the density variations causing a body force term in the momentum equation. The Boussinesq approximation is invoked for the fluid properties to relate density changes, and to couple in this way the temperature and concentration fields to the flow field. The concentration of diffusing species is assumed to be very small in comparison with other chemical species far away from the surface. Hence the Soret and Dufour effects are neglected. The stretching sheet is assumed to be subject to a power‐law wall temperature as well as to a power‐law wall concentration, in a parallel free stream.

Practical implications

Convective heat and mass transfer over a vertical stretching sheet in a parallel stream is very important for various design of technological process are hot rolling, wire drawing, glass‐fiber paper production, both metal and polymer sheets, for instance, in cooling of an infinite metallic plate in a cooling bath, the boundary layer along material handling conveyors, etc.

Originality/value

The paper studies the combined effects of thermal and mass diffusion over a vertical stretching sheet with surface mass transfer.

Abstract

Purpose

The purpose of this paper is to study the influence of thermally stratified medium on a free convection flow from a sphere, which is rotating about the vertical axis, immersed in a stably thermally stratified medium.

Design/methodology/approach

An implicit finite‐difference scheme in combination with the quasi‐linearization technique is applied to obtain the steady state non‐similar solutions of the governing boundary layer equations for flow and temperature fields.

Findings

The numerical results indicate that the heat transfer rate at the wall decreases significantly with an increasing thermal stratification parameter, but its effect on the skin friction coefficients is rather minimum. In fact, the presence of thermal stratification of the medium influences the heat transfer at wall to be in opposite direction, that is, from fluids to the wall above a certain height. The heat transfer rate increases but the skin frictions decrease with the increase of Prandtl number. In particular, the effect of buoyancy force is much more sensitive for low Prandtl number fluids (Pr = 0.7, air) than that of high Prandtl number fluids (Pr = 7, water). Also the skin friction in rotating direction is less sensitive to the buoyancy force as the buoyancy force acts in the streamwise direction for the present study of thermally stratified medium.

Research limitations/implications

The ambient temperature T∞∞ is assumed to increase linearly with height $h$. The viscous dissipation term, which is usually small for natural convection flows, has been neglected in the energy equation. The flow is assumed to be axi‐symmetric. The Boussinesq approximation is invoked for the fluid properties to relate density changes to temperature changes, and to couple in this way the temperature field to the flow field.

Practical implications

Free convection in a thermally stratified medium occurs in many environmental processes with temperature stratification, and in industrial applications within a closed chamber with heated walls. Also, free convections associated with heat rejection systems for long‐duration deep ocean powder modules where ocean environment is stratified are examples of such type.

Originality/value

The research presented in this paper investigates the free convection flow on a sphere, which is rotating with a constant angular velocity along its vertical axis in a stably thermally stratified fluid.

Abstract

Purpose

The purpose of this paper is to consider steady two‐dimensional mixed convection flow along a vertical semi‐infinite power‐law stretching sheet. The velocity and temperature of the sheet are assumed to vary in a power‐law form.

Design/methodology/approach

The problem is formulated in terms of non‐similar equations. These equations are solved numerically by an efficient implicit, iterative, finite‐difference method in combination with a quasi‐linearization technique.

Findings

It was found that the skin‐friction coefficient increased with the ratio of free‐stream velocity to the composite reference velocity and the buoyancy parameter while it decreased with exponent parameter. The heat transfer rate increased with the Prandtl number, buoyancy parameter and the exponent parameter.

Practical implications

A very useful source of information for researchers on the subject of convective flow over stretching sheets.

Originality/value

This paper illustrates mixed convective flow over a power‐law stretched surface with variable wall temperature.

Abstract

Reports on the authors' experience with a patient safety quality improvement program, intended to reduce the incidence and severity of adverse outcomes for emergency department (ED) patients aged ≥75. The Identification of Seniors at Risk scale was used for screening, and those at high risk were referred for appropriate intervention. The plan‐do‐study‐act improvement cycle was followed, conducting process evaluation to diagnose and correct implementation difficulties. Reports that: implementing an ED screening and referral program is deceptively difficult; process evaluation multidisciplinary working group meetings are an essential improvement tool; screening inclusion criteria had to be adapted to the subject population in order to make efficient use of staff time; the screening questions and process required ongoing assessment, revision, and local adaptation in order to be useful; and high‐risk screening in the ED is critical to a hospital system's ability to anticipate clinical problems; the plan‐do‐study‐act improvement cycle is a practical and useful tool for improving quality and systems in a real care setting.
