Palliative and curative care nurses' attitudes toward dying and death in the hospital setting

This paper explores the errors involved in the approximation of both the maximum and sum of two independent Beta random variables, each by another Beta random variable. The principal area of application is the time analysis of PERT networks, and the results are interpreted and discussed in terms of this application. The error was found to be acceptable for the greater part of the range of the parameters involved. The results will help practitioners estimate the mean and standard deviation of the completion time of PERT networks.     

Assessing Engineering Resilience for Systems with Multiple Performance Measures

Recently, efforts to model and assess a system's resilience to disruptions due to environmental and adversarial threats have increased substantially. Researchers have investigated resilience in many disciplines, including sociology, psychology, computer networks, and engineering systems, to name a few. When assessing engineering system resilience, the resilience assessment typically considers a single performance measure, a disruption, a loss of performance, the time required to recover, or a combination of these elements. We define and use a resilient engineered system definition that separates system resilience into platform and mission resilience. Most complex systems have multiple performance measures; this research proposes using multiple objective decision analysis to assess system resilience for systems with multiple performance measures using two distinct methods. The first method quantifies platform resilience and includes resilience and other “ilities” directly in the value hierarchy, while the second method quantifies mission resilience and uses the “ilities” in the calculation of the expected mission performance for every performance measure in the value hierarchy. We illustrate the mission resilience method using a transportation systems‐of‐systems network with varying levels of resilience due to the level of connectivity and autonomy of the vehicles and platform resilience by using a notional military example. Our analysis found that it is necessary to quantify performance in context with specific mission(s) and scenario(s) under specific threat(s) and then use modeling and simulation to help determine the resilience of a system for a given set of conditions. The example demonstrates how incorporating system mission resilience can improve performance for some performance measures while negatively affecting others.     

Is Managed Mental Health Treatment Psychotherapy?

The corporate takeover of mental health treatment has dramatically affected mental health treatment. Two essential constituents of psychotherapeutic process, the relationship between patient and therapist and the special communicative process associated with a talking treatment, have been significantly compromised. Therapists and patients are being forced to consider whether in the absence of confidentiality, self determination, and a secure treatment partnership managed mental health care can be called psychotherapy. Drawing on several detailed sessions from the managed treatment of a young woman, the writer concludes that the answer is no.     

Statistical and Historical Analyses of Nations Which Deviate From the Size-Density Law

We examine nations which deviate significantly from the ?2/3 sizedensity slope previously observed for the aggregated political subdivisions of 98 modern nations and previously derived from the theory of timeminimization. We correct Stephan’s original list of deviant nations, demonstrate that all slopes more negative than ?2/3 were due to the erroneous inclusion of cities in the original data sets, develop a theory to account for the less negative deviant slopes, and test the theory both through statistical manipulation of current data and through analysis of available historical data.     

Perceived importance of “social goals” in business organizations

Business organizations operate within a complex socio-technical environment. Interactions between these socio-technical dimensions and the managers' personal value systems are thought to influence managerial role patterns and decisions. This paper investigates shifts in perceived importance of “social goals” from a set of organizational goals. The research concludes that there has been no significant changes occurring in either the ordering or the clustering of organizational goals.     

Quality improvement in patient distribution at a major university student health center

Healthcare in a major university setting poses unusual challenges and great opportunities. Two traditionally challenging areas in patient distribution are the initial intake of allergy/immunization patients and the triage of outpatients in the general medical clinic. The authors describe the use of the FOCUS-PDCA quality improvement (QI) problem-solving process for each situation. After identifying major problems, the health center established cross-functional teams of experts representing the allergy/immunization and general medical clinics. The teams analyzed the problems with a flow chart and undertook studies to further elucidate causes and potential solutions. They listed potential solutions in order of priority and submitted them to the student health center director for review and initiation. Each team then used the PDCA (plan-do-check-act) cycle to put approved solutions into effect. Permanent improvements made in each area resulted in a more effective and efficient patient distribution system, favorable staff comment, and greater patient satisfaction.

Casual sex among Australian schoolies

This study of the casual sexual partnering of 570 male and 776 female Australian high school students on a schoolies week vacation expands on earlier research on factors that influence the sexual activity of vacationing youth. Over 60% of the men and nearly 40% of the women who engaged in sexual intercourse during schoolies week did so with a casual partner. We used logistic regression to test an expanded version of Triandis Theory of Interpersonal Behavior (TIB) in explaining casual sexual partnering. Situational experiences (similar to what others have called situational disinhibition), prior sexual experiences and intentions (similar to what others have called spillover) influenced casual sexual partnering. Different causal pathways were demonstrated for men and women.
