Preparing Students for Health Care Delivery of the Future: A Service Education Partnership

In conclusion, redesigning the senior leadership management theory course in our undergraduate baccalaureate nursing program to incorporate new concepts of managed care, case management, critical paths, and multidisciplinary collaborations was successful. Providing students with a "real world" project developing critical paths provided an opportunity for them to make a contribution to an organization while learning verbal and written collaborative skills that may prove crucial to their future in nursing. Critical path development projects will be pursued until those specific needs of the organization have been met. Other opportunities will become obvious for class projects as new challenges are presented for organizations to address in this ever-changing health care delivery system.

Assessing quality of nursing home care: the foundation for improving resident outcomes

Efforts to improve the quality of care and outcomes for nursing home residents are constantly of concern to state and federal regulators, nursing home providers, nursing home advocacy groups, and health policy researchers. The article describes a study that analyzed the quality indicators identified by the Health Care Financing Administration-sponsored Case Mix and Quality Demonstration Project using the Missouri nursing home Minimum Data Set database. The range of performance was considerable, and five of the indicators analyzed were risk adjusted to account for variation in resident acuity within facilities. Determining quality of care from assessment information that is routinely collected for nursing home residents has the potential to influence dramatically public policy decisions regarding reimbursement, recertification, and regulation and can play a vital role in improving resident outcomes.

Employee motivation: new perspectives of the age-old challenge of work motivation

In this qualitative study, the 1950s-1970s work of Frederick Herzberg, the father of work motivational research, was compared, and contrasted with current data study about management effectiveness to explore how employee motivation may have changed. Staff members and managers (N = 38), primarily from healthcare settings, but also from academic, public, and private sector businesses were interviewed. Interpersonal relations now ranks first as a motivating factor in this study. Recognition, the work itself, and responsibility are still ranked as critical motivating factors. These are important to understand as work is redesigned. Supporting positive interpersonal relations among subordinates, supervisors, and peers can be viewed as an effective management strategy to facilitate employee motivation. For employees, developing positive interpersonal relations with co-workers can enhance individual motivation and may improve job satisfaction.

Quantitative analysis of collagen gel contractile forces generated by dermal fibroblasts and the relationship to cell morphology

The force generated in granulation tissue during wound contraction is thought to be cell mediated; however, it is unclear whether contractile forces are generated by fibroblast locomotion or contraction of myofibroblasts. To help clarify this question the force of this contraction can now be determined accurately in a human dermal fibroblast collagen lattice system using a novel instrument known as a Culture Force Monitor. Three distinct phases of contraction of such collagen gels could be identified over the first 24 hours. Most of the force generated by human dermal fibroblasts was produced during the first stage in parallel with cell attachment and associated changes in cell shape, and the appearance of cell processes. During this initial 24 hours no evidence could be found for the presence of myofibroblasts, but stereoscopic and electron microscopic analysis at a range of time points indicated that migratory fibroblasts were present in the system. Comparison of the contraction profiles of cells extracted from other tissues (tendon and articular cartilage), and extracted by different means from the same tissue specimen, indicated that different populations of fibroblasts can be distinguished on the basis of their pattern of contractions. It would seem that most of the force generated in this model is a result of fibroblast attachment and movement within the collagen lattice. Furthermore, different groups of fibroblasts, even within the same tissue, may vary in their contraction (hence locomotory) activity.

A robust automatic clustering scheme for image segmentation using wavelets

The optimal features with which to discriminate between regions and, thus, segment an image often differ depending on the nature of the image. Many real images are made up of both smooth and textured regions and are best segmented using different features in different areas. A scheme that automatically selects the optimal features for each pixel using wavelet analysis is proposed, leading to a robust segmentation algorithm. An automatic method for determining the optimal number of regions for segmentation is also developed.
