Multivariate distributions defined in terms of contours

The paper deals with the problem of using contours as the basis for defining probability distributions. First, the most general probability densities with given contours are obtained and the particular cases of circular and elliptical contours are dealt with. It is shown that the so-called elliptically contoured distributions do not include all possible cases. Next, the case of contours defined by polar coordinates is analyzed including its simulation and parameter estimation. Finally, the case of cumulative distribution functions with given contours is discussed. Several examples are used for illustrative purposes.     

Asymptotic posterior normality for multiparameter problems

For asymptotic posterior normality in the one-parameter cases, Weng [2003. On Stein's identity for posterior normality. Statist. Sinica 13, 495–506] proposed to use a version of Stein's Identity to write the posterior expectations for functions of a normalized quantity in a form that is more transparent and can be easily analyzed. In the present paper we extend this approach to the multi-parameter cases and compare our conditions with earlier work. Three examples are used to illustrate the application of this method.     

Children of Adolescent Mothers: Cognitive and Behavioral Status at Age Six

The cognitive and behavioral status at age six years of 185 children of adolescent mothers (60.5% boys) were assessed using the mother (CBCL) and teacher (TRF) report forms of the Child Behavior Checklist and the Bracken Basic Concepts Scale. There was evidence for impairment in all areas of functioning. More than half of the sample exceeded the borderline clinical cutoff (T = 60) on either the CBCL or TRF Total Problem score, and nearly half the sample had Bracken scores that were more than 1 SD below the normative mean. Only 26.9% of the children were in the normal range on all three measures. These results are discussed in terms of implications for social work practice with children and adolescent mother families.     

Gender Competition and the Preservation of Community in the Allocation of Administrative Positions in Small Rural Towns in Montana: A Research Note1

Abstract Assignment of administrative positions in a sample of rural towns is demonstrated to be significantly associated with gender. Most civil administrators are women, while most legal and educational administrators are men. The difference indicates structural assignment of positions by gender. Gender and administrative position are demonstrated to have zero-order correlations with perceptions of two important behaviors for community: migration and social problems. The characteristics of the occupation and of the administrators are qualitatively different. The data are compiled from interviews with seventy administrators in five pairs of small towns in Montana, ranging in size from about 200 to approximately 7,000 residents. Each pair contains one agricultural and one scenic recreational town. Comparatively, more women were employed in agricultural towns. Many rural women who become administrators, particularly long-term administrators, may be selected for reasons that help preserve the community by providing opportunities for themselves and their families.     

Interparental Conflict and Preschoolers' Peer Relations: The Moderating Roles of Temperament and Gender

The relations between destructive interparental conflict (IPC) and three‐ to six‐year‐olds’ (N = 62) peer relations were examined as a function of child temperament and gender. Regression analyses indicated that effortful control moderated the relations of IPC with children's amount of peer interaction as well as with their problematic relations with peers. Specifically, high IPC was associated with low amount of interaction and high problematic relations for preschoolers low in effortful control, but it was related to high amount of interaction and low problems for those high in effortful control. Additionally, gender differences in the relations between IPC and the amount of peer interaction indicated that IPC was negatively related to the amount of interaction for girls but positively related to the amount for boys. The findings highlight the need for examining individual differences in the relations between IPC and the development of early peer relations.     

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.     

The parenting of adolescents in Britain today

In this paper it is noted that increased attention has been paid to the topic of parenting in recent years. However, most of this attention has been concentrated on the parenting of young children, with the parenting of adolescents being largely ignored by both practitioners and academics. The paper reviews the available research on the parenting of teenagers, and shows how this could be of use to those who live with young people. The article concludes with some suggestions for new research, and argues that there is an urgent need for greater support and information for this group of parents.     

Urban tree cover: an ecological perspective

Analysis of urban tree cover is generally limited to inventories of tree structure and composition on public lands. This approach provided valuable information for resource management. However, it does not account for all tree cover within an urban landscape, thus providing insufficient information on ecological patterns and processes. We propose evaluating tree cover for an entire urban area that is based on patch dynamics. Treed patches are classified by their origin, structure, and management intensity. A patch approach enables ecologists to evaluate ecological patterns and processes for the entire urban landscape and to examine how social patterns influence these ecological patterns and processes.     

Informing the Public About Uncertain Risks

Many problems arise in connection with the communication of risk information. In this article the content of the information communicated is taken as a starting-point for analyzing the risk communication process. We studied the way in which authorities communicated health risks to local residents in Dutch soil pollution situations and found that communication problems were characterized more by misunderstanding and conflict between parties with different views and interests than by a lack of understanding. Therefore, it is important to look more closely at the way the communicators of information (in our cases, officials) select risk information from risk assessments, and to study the effects that the information selected has on the receivers (in our cases, residents). Both the process of selection by the officials and the process of interpretation by the residents will be shown to be influenced by the different institutional backgrounds. The article presents a new approach to risk communication. Both the risk information presented by the authorities and the public reactions to this risk information are considered to reflect the institutional background of authorities and residents, and can be analyzed in these terms. Such an approach has consequences for the study of risk communication and the manner in which it is practiced.
