Comparing swimsuits in 3D

In competitive swimming, suits have become more important. These suits influence friction, pressure and wave drag. Friction drag is related to the surface properties whereas both pressure and wave drag are greatly influenced by body shape. To find a relationship between the body shape and the drag, the anthropometry of several world class female swimmers wearing different suits was accurately defined using a 3D scanner and traditional measuring methods. The 3D scans delivered more detailed information about the body shape. On the same day the swimmers did performance tests in the water with the tested suits. Afterwards the result of the performance tests and the differences found in body shape was analyzed to determine the deformation caused by a swimsuit and its effect on the swimming performance. Although the amount of data is limited because of the few test subjects, there is an indication that the deformation of the body influences the swimming performance.     

Differential mortality risks from violent causes for foreign- and native-born residents of the USA

This paper examines the differences in adult violent causes (homicide, suicide, vehicle accidents, and otheraccidents) for mortality risks between the Americanforeign- and native-born adult populations, whileconsidering the length of time lived in the USA and the influences of other socio-demographic characteristics. Data came from the National Health InterviewSurvey-National Death Index linked file for the years1989--1995. Cox proportional hazards modelsestimate the association between nativity, length ofstay, and mortality risk for each violent cause. Theresults show that foreign-born persons differ in their risks of violent death vis-á-vis the native-bornpopulation by the amount of the time they have livedin the USA. In particular, recent immigrants (lessthan 15 years) display higher risks fromhomicide, lower risks from suicide, and lower risksfrom other accidents (not vehicle) than thenative-born individuals. This pattern is differentfor longer-term immigrants (15 or more years) whohave, for the most part, similar risks from othercauses of violent death compared to native-bornresidents. The findings suggest that there arecompositional differences between immigrants by length of stay and that the process of acculturation mayinclude the amplification or diminution of risks ofvarious causes of violent death.     

The multiattribute evaluation of program-planning contractors

This note describes how the theory of measurable multiattribute value functions was used to evaluate the proposals of three competing subcontractors for a program-planning project undertaken by Los Alamos National Laboratory. The purpose of the program-planning project was to develop a methodology for the evaluation of alternative long-range strategies for the achievement of controlled thermonuclear fusion. A measurable multiattribute value function was developed based on eleven criteria. Eight judges made evaluations on each of these criteria, and their judgments were synthesized to identify the winning subcontractor. While we emphasize details associated with this specific application, we expect the problem structure and methodology to be amenable to other contractor-and proposal-evaluation efforts after only minor modifications.     

The Occupational Assimilation of Hispanic Immigrants in the U.S.: Evidence from Panel Data1

This study focuses on the occupational component of the labor market adjustment of Hispanic immigrants. The author asks whether Hispanic immigrants assimilate with natives and what factors influence occupational attainment. The findings suggest that years since migration narrow the socioeconomic gap between Hispanic immigrants, their U.S.‐born Hispanic counterparts, and non‐Hispanic whites. The level of human capital affects the rate of occupational mobility and determines whether convergence occurs in the groups’ socioeconomic occupational status. The occupational status of Hispanic immigrants with low human capital remains fairly stable and does not converge with that of non‐Hispanic whites. However, those with high human capital experience upward occupational mobility. In part, their occupational assimilation is driven by the acquisition of human capital among younger Hispanic immigrants.     

ABORIGINAL AUSTRALIA AND NATURAL JUSTICE

Aboriginal men and women continue to be grossly over-represented in police and prison custodial settings. In 1987 the Royal Commission into Aboriginal Deaths in Custody was established primarily because deaths in custody were far too common. Commission findings, including over 300 recommendations, were finally publicly released in 1991. In a number of significant ways, it was revealed that the ‘scene had been set’ for premature death both inside and outside custody. In part that ‘scene had been set’ because of the ongoing consequences of colonisation and the legal doctrine euphemistically known as ‘natural justice’. ‘Natural justice’ implies, rather than assures, equality for all before the law. Such fundamental inequality found, and continues to find, intense and tragic expression in high levels of incarceration and deaths in custody.     

Integrating acquired physician practices

Many strategies have been suggested to accomplish successful physician integration, including stock ownership in a for-profit entity created by the health system, sharing in the cost efficiencies caused by changing practice patterns, and compensation attached to service and access standards. One thing that executives overlook goes beyond financial concerns and yet hits at the heart of what is important to most physicians. That is maintaining their ability to make decisions regarding their own practice environment both clinically and administratively. United Health describes its physician-administrator team model, developed to enhance the physician integration process.     

Patient progress modelling and results in Wilm's Tumour

The report describes the development of a mathematical model of the progress of patients with Wilm's Tumour using the methodology developed by Jackson & Aspden [1, 2]. The model incorporates two prognostic factors which are shown to influence patient progress. These are the stage of the tumour and the age of the patient at presentation. The model proved adequate to represent an initial set of patient data, and comparison runs were performed with data from a later time period. These runs highlighted changes in patient progress between the two groups and illustrated the usefulness of the model in this type of analysis. The analysis also underlined the poor prognosis of patients over 5 years old who relapsed.     

PEGASE Program: Identification of babies in the child protection system at risk of developmental delays or disorders and the implementation of a ‘supra-optimal’ care pathway

The importance of the first three years of life for children's development and the consequences for their general health in adulthood have been widely documented in the international literature, including the benefits of early identification and intervention programs. Additionally, convergent research has highlighted wide-ranging negative trajectories attributable to both the short and long-term consequences of abuse and neglect and their neurobiological impact on health and development. However, formal identification processes and the use of standardised screening tools in child protection remain relatively rare despite the potential societal impact of child maltreatment in terms of public and economic health. Moreover, delays between the initial identification of mental health problems and health and developmental disorders, and the introduction of appropriate interventions persist. Abused and neglected infants risk an exacerbation of the consequences of early maltreatment due to insufficient access to prompt assessment and treatment, including appropriate responses to their health needs. The aim of this article is to present the PEGASE program, an innovative French program for very young children in care, which is modelled on the care of premature babies. By setting up an early care pathway, it aims to ensure adequate medical follow-up – both somatic and psychiatric – through standardised examination and tailored interventions in order to limit the adverse health and developmental consequences of abuse. The presentation of the PEGASE program is supplemented by a case study.
