Adolescents' Emotional Experiences of Mother–Adolescent Conflict Predict Internalizing and Externalizing Symptoms

Research on adolescent emotion has generally focused on expressions of emotion; however, there are reasons to believe that adolescents' experiences of emotion may be related to adolescent development in unique and important ways. This study examined the relation of adolescents' emotional experiences of conflict with their mothers to their internalizing and externalizing symptoms at three time points, each a year apart. After participating in videotaped conflict negotiation tasks with their mothers, adolescents (N=80) watched the videotape of their interactions and used a joystick to make continuous ratings of how negative, positive, or neutral they felt during the discussions. Hierarchical Linear Modeling was used to assess relations among their continuous emotion ratings and their internalizing and externalizing symptoms 1 year before the interaction task, at the time of the interaction task, and 1 year later. Adolescents' externalizing symptoms at the time of the conflict task were associated with negative emotion that decreased across the conflict discussion. Relations between emotional experience and internalizing symptoms a year later were moderated by adolescent gender, revealing that a tolerance for increasing negative emotion predicts fewer future internalizing symptoms for girls. The importance of adolescents' ability to tolerate negative emotion during normal developmental conflicts is discussed.     

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.     

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.     

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.     

Ethnic Transformation in Rural California: Looking Beyond the Immigrant Farmworker

Abstract Communities in rural California are becoming increasingly Latino. Using a quantitative database of 288 rural communities, together with qualitative data collected in the San Joaquin Valley, we examine the processes through which this ethnic transformation is occurring. Most studies have focused on Latino immigration as the cause of changing ethnic composition. We find that non-Latino population growth, as well as Latino population growth, accounts for the relative differences in changing community ethnicity. Most important for explaining migration among Latinos are housing costs and year-round job availability. Among white non-Latinos, ethnic conflict and perceptions of community deterioration better explain migration decisions. As a result of these changes, places in rural California are becoming increasingly economically and ethnically differentiated.     

The Family Dynamics of School Phobics

Summary A casework based method of assessment was devised to examinethe family dynamics of school phobic children. There was significantdifferences found between the family interaction of male andfemale school phobic children. The relationships were dichotomizedalong gender lines, that were broadly oedipal in nature. Thesefindings and methodological problems were discussed     

Bayesian analysis of human movement curves

Summary.  We consider the Bayesian analysis of human movement data, where the subjects perform various reaching tasks. A set of markers is placed on each subject and a system of cameras records the three-dimensional Cartesian co-ordinates of the markers during the reaching movement. It is of interest to describe the mean and variability of the curves that are traced by the markers during one reaching movement, and to identify any differences due to covariates. We propose a methodology based on a hierarchical Bayesian model for the curves. An important part of the method is to obtain identifiable features of the movement so that different curves can be compared after temporal warping. We consider four landmarks and a set of equally spaced pseudolandmarks are located in between. We demonstrate that the algorithm works well in locating the landmarks, and shape analysis techniques are used to describe the posterior distribution of the mean curve. A feature of this type of data is that some parts of the movement data may be missing—the Bayesian methodology is easily adapted to cope with this situation.
