Survival dilemmas: Case study of an adult child of a schizophrenic parent

This article describes aspects of the treatment of an adult child of a schizophrenic parent. Many theories on irrationality in the family setting illuminate the range of impingement on the child's reality when a parent is disturbed in this way. Current research has absorbed itself in interpretations of data on risk, vulnerability, disorder, and early trauma, which have implications for prevention as well as therapeutic treatment of the adult survivor. Profound effects on Ms. P's early development are elaborated in the therapy, in which the treatment stance is influenced by Kohut's theories of the self, particularly as applied to the establishment within the holding environment of specific transferences that facilitate reconstructive work.     

ON BOOTSTRAP HYPOTHESIS TESTING

We describe methods for constructing bootstrap hypothesis tests, illustrating our approach using analysis of variance. The importance of pivotalness is discussed. Pivotal statistics usually result in improved accuracy of level. We note that hypothesis tests and confidence intervals call for different methods of resampling, so as to ensure that accurate critical point estimates are obtained in the former case even when data fail to comply with the null hypothesis. Our main points are illustrated by a simulation study and application to three real data sets.     

Using Related Samples in Assessing Conformance to Safety Goals: A Nuclear Reactor Safety Application

Quantifying safety goals is a key to the regulation of activities which are beneficial on the whole but entail some risks in being performed. Determining compliance with safety goals involves dealing with uncertainties. A recent article by Bier^(I) describes some of the difficulties encountered using measures with uncertainty to determine compliance with safety goals for nuclear reactors. This paper uses a hierarchical Bayes approach to address two practical modeling problems in determining safety goal compliance under uncertainty: (1) allowing some modeling assumptions to be relaxed, and (2) allowing data from previous related samples to be included in the analysis. The two issues effect each other to the extent that relaxing some assumptions allows the use of a broader range of data. The usefulness of these changes and their impact on assessing safety compliance for nuclear reactors is shown.     

A BETA-OPTIMAL TEST OF THE EQUICORRELATION COEFFICIENT

This paper considers the problem of testing for nonzero values of the equicorrelation coefficient of a standard symmetric multivariate normal distribution. Recently, SenGupta (1987) proposed a locally best test. We construct a beta-optimal test and present selected one and five percent critical values. An empirical power comparison of SenGupta's test with two versions of the beta-optimal test and the power envelope shows the relative strengths of the three tests. It also allows us to assess and confirm Efron's (1975) rule of when to question the use of a locally best test, at least for this testing problem. On the basis of these results, we argue that the two beta-optimal tests can be considered as approximately uniformly most powerful tests, at least at the five percent significance level.     

NONPROFIT INCORPORATION AMONG MOVEMENTS OF THE POOR:

Social movement scholars have begun to note the widespread use of nonprofit incorporation by social movement organizations (SMOs) in the United States. They argue that nonprofit incorporation is a voluntary act that ultimately leads to moderation in goals and tactics. I examine this argument with ethnographic data on fifteen homeless SMOs that operated in eight U.S. cities. I identify six pathways to adoption or nonadoption of nonprofit form and find that moderation, when it occurs, is not a function of nonprofit incorporation per se but of the particular pathway by which an SMO came to adopt nonprofit form. I discuss the implications of these findings for SMOs in general and for understanding the broader debates about organizational autonomy and external control of SMOs.     

MODERN MAGIC

The suggestion that students at present day universities participate in magic at exam time may seem unusual. This study views "magic" as behavior directed toward achieving an outcome, involving many everyday and commonplace acts, but seeming to rely for success on some mystical element. Hundreds of personal accounts from students describing their exam-related behaviors provide the basis for a classification system of their "magical practices." The classification yields findings regarding the use of magic for luck and the avoidance of bad luck. Student magic is found to be idiosyncratic, inconsistent, and never malevolent as it often is in preliterate societies. Such differences between preliterate magic, other modern forms, and student magic are related to the complexity and heterogeneity of the larger society, the cultural norms, and the degree of collective action involved.     

Knowledge and information about drugs in Australia

This article uses a national population survey conducted in 1988 to examine drug information needs within the Australian population. The analysis concentrates on three types of informational needs--knowledge and contact with drug services, the nature of the drug information sought, and the sources of drug information. The results show that almost half of the respondents in the survey considered that they had an adequate amount of information about drugs and there were generally high levels of factual knowledge about the drug and alcohol services available in the community. Knowledge of drug services was found to be unrelated to the need for information, although high levels of knowledge did correlate with a willingness to use a variety of medical, welfare, and social support services to obtain information. The data indicated that contact significantly correlated with both a desire for information and a willingness to consult a variety of services. Finally, users of all types of drugs reported higher levels of knowledge, with users of illicit drugs, in particular, expressing a greater desire for information about all types of drugs and an increased willingness to use a variety of welfare and social support agencies.     

The trouble with foster care: the impact of stressful 'events' on foster carers

Summary The article draws on the first stages of a large-scale longitudinalstudy into foster care with 'looked after' children. It usesdata supplied by 950 foster carers in response to a postal questionnairedesigned to document the proportions who had experienced oneor more of six potentially stressful 'events': breakdowns ordisruptions, allegations, relationship with birth parents, familytensions, 'tug of love' cases, and other disagreements withsocial services. The article uses carers' comments to describetheir reaction to the 'events'. It then examines the relationshipbetween the 'events' and measures of carer stress, satisfactionwith fostering, and intentions to continue fostering. Overall,two-thirds of the sample had experienced one or more of these'events' and these were associated with a measure of mentalill-health and with attitudes towards continuing fostering.     

Who captures the marks for the Petersen estimator?

Summary.  We examine the claim that the well-known Petersen estimator which is used in population size estimation was not in fact used by the scientist after whom it is named. We show how, in the early years of the last century, the modern use of the Petersen estimator grew from that of the fishing coefficient. Contending with the somewhat conflicting claims that were made at the time, and what by modern standards is poor referencing of sources, we investigate where the credit lies for these concepts, and the principles and protocols which support them. We assess also how far attributions of credit were affected by practical considerations, and the history of the estimator by the nature of the problems being pursued. We identify scientists whose early work on marking and estimating fish populations deserves more credit than it has received.     

Estimation of the number of studies with positive trends when studies with negative trends are present

A two-point estimator is proposed for the proportion of studies with positive trends among a collection of studies, some of which may demonstrate negative trends. The proposed estimator is the y-intercept of the secant line joining the points (a, F?(a)) and (b, F?(b)), where F?(p) is the empirical distribution function of p-values from one-tailed tests for positive trend derived from the individual studies. Although this estimator is negatively biased for any choice of the points 0 ≤ a < b ≤ 1, the bias is less than that of the previously proposed one-point estimator defined by setting b = 1. The bias of the two-point estimator is smallest when a and b approach the inflection point of the true distribution function, E [F?(p)]. The utility of the two-point estimator is demonstrated by using it to estimate the number of male-mouse liver carcinogens among carcinogenicity studies conducted by the National Toxicology Program.
