Adapting the jury trial for program evaluation: A report of an experience

A portion of the graduate program in clinical community psychology at SUNY Buffalo was subjected to a jury trial as a form of program evaluation. The theory of the trial as evaluation, the problems of implementation, and a posttrial evaluation are discussed. The trial, while time-consuming, especially in its pretrial phases, has the potential for presenting a dramatic picture of a program through the medium of human testimony. The jury was able to arrive at clear decisions on questions put to it, with a high degree of confidence. Decision makers accepted some of the jury's conclusions, and subjective evidence suggests that many of the controversial issues which generated the trial were resolved for the group by the procedure. The posttrial evaluation revealed limitations, such as evidence which was not presented at the trial. The experience proved useful for purposes of interdisciplinary education, providing another lens through which the evaluation problem could be viewed.     

The dangers posed by saddle points, and other problems, when using central composite designs

This paper discusses two problems, which can occur when using central composite designs (CCDs), that are not generally covered in the literature but can lead to wrong decisions-and therefore incorrect models-if they are ignored. Most industrialbased experimental designs are sequential. This usually involves running as few initial tests as possible, while getting enough information as is needed to provide a reasonable approximation to reality (the screening stage). The CCD design strategy generally requires the running of a full or fractional factorial design (the cube or hypercube) with one or more additional centre points. The cube is augmented, if deemed necessary, by additional experiments known as star-points. The major problems highlighted here concern the decision to run the star points or not. If the difference between the average response at the centre of the design and the average of the cube results is significant, there is probably a need for one or more quadratic terms in the predictive model. If not, then a simpler model that includes only main effects and interactions is usually considered sufficient. This test for 'curvature' in a main effect will often fail if the design space contains or surrounds a saddle-point. Such a point may disguise the need for a quadratic term. This paper describes the occurrence of a real saddle-point from an industrial project and how this was overcome. The second problem occurs because the cube and star point portions of a CCD are sometimes run as orthogonal blocks. Indeed, theory would suggest that this is the correct procedure. However in the industrial context, where minimizing the total number of tests is at a premium, this can lead to designs with star points a long way from the cube. In such a situation, were the curvature test to be found non-significant, we could end with a model that predicted well within the cube portion of the design space but that would be unreliable in the balance of the total area of investigation. The paper discusses just such a design, one that disguised the real need for a quadratic term.     

Using Auxiliary Time-Dependent Covariates to Recover Information in Nonparametric Testing with Censored Data

Murrayand Tsiatis (1996) described a weighted survival estimate thatincorporates prognostic time-dependent covariate informationto increase the efficiency of estimation. We propose a test statisticbased on the statistic of Pepe and Fleming (1989, 1991) thatincorporates these weighted survival estimates. As in Pepe andFleming, the test is an integrated weighted difference of twoestimated survival curves. This test has been shown to be effectiveat detecting survival differences in crossing hazards settingswhere the logrank test performs poorly. This method uses stratifiedlongitudinal covariate information to get more precise estimatesof the underlying survival curves when there is censored informationand this leads to more powerful tests. Another important featureof the test is that it remains valid when informative censoringis captured by the incorporated covariate. In this case, thePepe-Fleming statistic is known to be biased and should not beused. These methods could be useful in clinical trials with heavycensoring that include collection over time of covariates, suchas laboratory measurements, that are prognostic of subsequentsurvival or capture information related to censoring.     

The im/mobilities of ‘sometimes-migrating’ for abortion: Ireland to Great Britain

ABSTRACT

This paper furthers the concept of im/mobilities through an investigation of the reproductive mobilities of women migrating for abortion from Ireland (north and south) to Great Britain. Where more often the focus of reproductive mobilities concerns the movement of people and matter in order to reproduce, there is less (although some) attention to movement aligned with the prevention of reproduction. We consider the variegated im/mobilities of conception not brought to birth, in the frictional movement of people, things, ideologies and imaginations in staying with and moving beyond the dichotomy of mobility and immobility. We engage in transdisciplinary dialogue between mobilities and migration studies. Hence, underlying this exploration is the concept of the ‘sometimes-migrant’, used to challenge binary oppositions between mobility and immobility, broader conceptualisations of ‘migrants’ as ‘exceptional’, and more specifically the notion of travelling for abortion as ‘abortion-tourism’. We adopt the call to focus on different incarnations of the ‘sometimes-migrant’ in the form of women travelling temporarily across national borders of intermittent porosity in order to seek care that is not available in their own country. Intersections of migration and mobilities reveal the ways women are im/mobilised through geopolitical and cultural practices at local and global scales.     

Children of the closet: a measurement of the anxiety and self-esteem of children raised by a non-disclosed homosexual or bisexual parent

This research examined whether a parent's non-disclosure of his or her homosexual or bisexual orientation within the family unit negatively affects self-esteem and anxiety in children, as measured in adulthood. Thirty-six subjects indicated that they had not known of their parent's sexual orientation until an average age of sixteen for the children of lesbian or bisexual mothers, and twenty-two for the children of gay or bisexual fathers. This group's scores on the Rosenberg Self-Esteem Scale, the Marlowe Crowne Social Desirabilty Scale and the State-Trait Anxiety Scale were compared to scores obtained by sixty-three participants who did not have a homosexual/bisexual parent. The number of years a secretive environment surrounded the child was measured, as were participants' attitudes about the secret sexual identity. Although the study did not find that adults previously raised with a closeted parent had significantly higher levels of anxiety or lower levels of self-esteem, results indicated that those who had been raised as children with non-disclosed lesbian mothers showed a significantly higher level of self-esteem than participants with heterosexual parents. Implications of the findings for the targeted population are discussed.     

Global patterns of healthy life expectancy for older women

This paper focuses on patterns of healthy life expectancy for older women around the globe in the year 2000, and on the determinants of differences in disease and injury for older ages. Our study uses data from the World Health Organization for women and men in 191 countries. These data include a summary measure of population health, healthy life expectancy (HALE), which measures the number of years of life expected to be lived in good health, and a complementary measure of the loss of health (disability-adjusted life years or DALYs) due to a comprehensive set of disease and injury causes. We examine two topics in detail: (1) cross-national patterns of female-male differences in healthy life expectancy at age 60; and (2) identification of the major injury and disability causes of disability in women at older ages. Globally, the male-female gap is lower for HALE than for total life expectancy. The sex gap is highest for Russia (10.0 years) and lowest in North Africa and the Middle East, where males and females have similar levels of healthy life expectancy, and in some cases, females have lower levels of healthy life expectancy. We discuss the implications of the findings for international health policy.     

For the love of the children: the coming out process for lesbian and gay parents and stepparents

This research investigated the coming out decision and process for 23 lesbian and gay custodial stepfamilies. We argue that lesbian and gay stepfamilies represent a unique type of family, distinct from heterosexual stepfamilies and from lesbian and gay families who have children within the context of a lesbian or gay relationship. The coming out process is one developmental challenge that distinguishes lesbian and gay stepfamilies from these other types. Through interviews with both lesbian and gay parents and stepparents we explored their coming out process to significant others: the children, families of origin and ex-spouses. We discuss those factors influencing the decision and the consequences that developed in light of these decisions. Findings show that the coming out process for lesbian and gay co-parents is a flexible and familial one, primarily influenced by and centered around the needs of the children.     

The developing program on social indicators at the U.S. Bureau of the Census

The Bureau of the Census Fiscal Year 1978 Budget provides funds for the first time for beginning a modest but coordinated effort in the field of social indicators and associated activities. The Bureau, buttressed by the advice and participation of other Government agencies, organizations and individuals outside of the Federal establishment long interested in social indicators, intends to:

1. consolidate and extend the development of the concepts and principles advanced previously relating to social indicators;
2. continue and expand the efforts and communication network established at the Office of Management and Budget, in connection with the preparation of the Social Indicators 1973 and 1976 reports;
3. systematically identify and assemble information sets and bits that are contained in censuses and surveys, household and establishment universes, administrative records, studies and projects capable of contributing to social indicator and social accounting development;
4. establish the basic analytic framework and an orderly set of detailed interrelated social accounts capable of being aggregated or disaggregated to appropriate levels of abstraction; and
5. prepare research and analytic studies and make available information generated from the social indicator and social accounting efforts at the Bureau, subject to limitations associated with confidentiality and copyright provisions pertaining to private sources of information.

The organizational structure to carry out this program consists of four primary work centers: information, social indicators, social accounts, and special studies. The structure is designed to provide for continuity of purpose, improve chances for individual achievement and group benefit, and to generate products that will contribute to a more accurate understanding of life experiences in the context of the interplay of social and economic forces and political and juridical institutions.
