An individual measure of relative survival

Summary.  Relative survival techniques are used to compare survival experience in a study cohort with that expected if background population rates apply. The techniques are especially useful when cause-specific death information is not accurate or not available as they provide a measure of excess mortality in a group of patients with a certain disease. Whereas these methods are based on group comparisons, we present here a transformation approach which instead gives for each individual an outcome measure relative to the appropriate background population. The new outcome measure is easily interpreted and can be analysed by using standard survival analysis techniques. It provides additional information on relative survival and gives new options in regression analysis. For example, one can estimate the proportion of patients who survived longer than a given percentile of the respective general population or compare survival experience of individuals while accounting for the population differences. The regression models for the new outcome measure are different from existing models, thus providing new possibilities in analysing relative survival data. One distinctive feature of our approach is that we adjust for expected survival before modelling. The paper is motivated by a study into the survival of patients after acute myocardial infarction.     

THE AURA OF "HIGH TECH" IN A WORLD OF MESSY PRACTICE

This study employs interlocking analytical devices from the perspectives of several disciplines to explore members' meanings through definitions of "high technology" given by workers in design engineering. The comparative analysis employs concepts from art history, sociology of culture, anthropology and science studies to explore the appeal of "high technology" in comparison with the aura of original artworks and the status accrued by symbolic tools. Additionally, the role standardization has played in the development of engineering as a profession is explored in historical context as are the recurring themes of speed and "the new." The findings reveal that how engineers use new technologies in the world of messy practice and their conceptual framework regarding so-called "high technology" do not map well onto one another. The study illustrates the perspective of science and technology studies that views all technology as socially shaped and society shaping, its construction accomplished through messy patched-up practices rather than clean, linear paths or perfect techniques.     

DETERMINING OPTIMAL SHIFT SCHEDULES FOR TELEPHONE TRAFFIC EXCHANGE OPERATORS

A branch and bound algorithm is presented for determining the minimum number of telephone operators, and their shift schedules, required to meet demand that varies over a 24 hour operating period. An integer linear programming formulation is used, and the algorithm is described in terms of its separation, relaxation, fathoming, and branching procedures. Computational results are provided, using actual operating data. The results indicate that practical sized problems can be solved by the algorithm, involving as many as 100 different shift type variables and demand profiles typical of those encountered in many telephone traffic exchanges.     

Wealth Inequality in Black and White: Cultural and Structural Sources of the Racial Wealth Gap

Using data from the 2013 Survey of Consumer Finances, this research examines competing and complementary cultural and structural explanations of the sources of racial differences in wealth. We use OLS regression and quantile regression to identify the major individual-level sources of wealth differences between African Americans and whites. Whites have more favorable wealth characteristics than do African Americans on all of the variables in the analysis: gender of household head, bankruptcies, spending patterns, stock ownership, business ownership, home ownership, inheritance, educational attainment, income, occupation, age, and number of children. Cultural factors, having a female-headed family, spending patterns, and inheritance account for little of the racial wealth gap. Racial differences in income, stock ownership, and business ownership account for much of the explained racial wealth gap. Moreover, compared with whites, African Americans receive significantly lower wealth returns to education, age, income, stock ownership, and business ownership. We discuss the implications of our findings.     

Predicting the recipients of social work support,and its impact on emotional and behavioural problems in early childhood

This paper examines the recipients of social work support in the Millennium Cohort Study. Using panel analysis and fixed effects models, it investigates the factors that lead to the receipt of any type of social work support for individuals with young children and the effects of this support on changes in the prevalence of emotional and behavioural problems in these children. We find that divorce or separation, and episodes of homelessness are two important factors that lead to the receipt of social work support. Mothers with male children are also more likely to receive social work support. However, we find no clear evidence that social work support has any effect on changes in children's emotional and behavioural problems over time. The implications of these findings for social work research and for practice and policy are discussed.     

Validation of the Australian Midwifery Standards Assessment Tool (AMSAT): A tool to assess midwifery competence

Background

There is no current validated clinical assessment tool to measure the attainment of midwifery student competence in the midwifery practice setting. The lack of a valid assessment tool has led to a proliferation of tools and inconsistency in assessment of, and feedback on student learning.

The Modern Mystique: Institutional Mediation of Hegemonic Motherhood

This study examines the means by which privileged mothers comply to the dominant expectations of intensive mothering. As women struggle with the complicated, and often contradictory, experience of meeting the demands of the dominant ideology, we examine the mediating role of an institution, in this case the most popular maternal support organization in the United States—Mothers of Preschoolers (MOPS). Organizations such as MOPS create an ideal cultural site for reinforcing ideologies that promulgate unattainable standards of perfection. Data were collected from observations of two MOPS groups, in‐depth interviews, and ethnographic content analysis of organizational materials. This dominant organization supports mothers by discouraging them from questioning the expectations of intensive mothering or considering alternative methods of parenting, which reinforces intensive mothering as the gold standard of parenting.     

Adoption Issues: Preparation of Psychologists and an Evaluation of the Need for Continuing Education

This study is an investigation of the level of preparation psychologists have in dealing with adoption issues and an assessment of the need for further education in treating triad members. A questionnaire was mailed to 497 psychologists randomly selected from the National Register of Health Service Providers in Psychology who received doctoral degrees between the years of 1990 and 1996. Two hundred and ten psychologists, all of whom were currently treating clients, participated in the study. Psychologists completed a Likert rating of their sense of preparation to treat triad members. The largest group (51%) rated themselves as Somewhat prepared, with the second largest group (23%) rating themselves as Not very prepared. Ninety percent reported they needed more education in adoption, and 81% reported interest in taking a continuing education course in adoption. Of the 210 participants, only 67 reported taking courses that dealt with adoption as part of their formal education. Of those psychologists who reported taking courses that involved adoption, they averaged only 1.3 courses during their undergraduate education, and 1.5 courses during graduate education, while the remaining 143 psychologists received no education in this area. When one considers the proportion of triad members seen clinically, this study suggests psychologists need more education and background information about the effects of the adoption process.
