Data analysis and the connectivity of random graphs

This paper presents empirical information on the adequacy of an asymptotic approximation developed by Erdös and Rényi dealing with the minimum number of lines needed to connect a random graph. It is shown that the approximation is poor for several data analysis applications of the result previously published in the behavioral sciences.     

OUTCOME EVALUATION OF BEHAVIORAL PARENT TRAINING AND CLIENT-CENTERED PARENT COUNSELING FOR CHILDREN WITH CONDUCT PROBLEMS1

The central question addressed was, how effective is parent training in reducing conduct problems in children in comparison to client-centered parent counseling? A secondary question was the relative effectiveness of the two treatment groups in comparison to a wait control group that when untreated during the 8-week period of treatment provided the other groups. Families of 36, 5- to 12-year-old conduct problem children were screened and assigned at random to treatment groups, but wait control group assignment depended upon therapist availability. Supervised graduate student therapists conducted 10 treatment sessions for each family. Parent reports and paper and pencil tests of child deviance and parent satisfaction showed a superior outcome for behavioral over the client-centered and wait control groups, and no differences between the latter two groups. At follow-up there was no maintenance of this superiority. Home observation data showed no advantage of behavioral over client-centered treatment, and these two groups did not improve significantly more than the wait control group. These results were discussed in the light of possible interactions between treatment and measurement, and methodological and sampling differences between this and other studies.     

Using empowerment theory in collaborative partnerships for community health and development

Models of community empowerment help us understand the process of gaining influence over conditions that matter to people who share neighborhoods, workplaces, experiences, or concerns. Such frameworks can help improve collaborative partnerships for community health and development. First, we outline an interactive model of community empowerment that describes reciprocal influences between personal or group factors and environmental factors in an empowerment process. Second, we describe an iterative framework for the process of empowerment in community partnerships that includes collaborative planning, community action, community change, capacity building, and outcomes, and adaptation, renewal, and institutionalization. Third, we outline activities that are used by community leadership and support organizations to facilitate the process of community empowerment. Fourth, we present case stories of collaborative partnerships for prevention of substance abuse among adolescents to illustrate selected enabling activities. We conclude with a discussion of the challenges and opportunities of facilitating empowerment with collaborative partnerships for community health and development. This work was supported by Kansas Health Foundation Grants 9206032B and 9206032A to support and evaluate community partnerships to prevent adolescent substance abuse. Thanks to Tom Wolff for sharing his wisdom about community coalitions so generously, and to Bill Berkowitz and anonymous reviewers for thoughtful comments on an earlier version of this manuscrpt. We also thank our colleagues from the Kansas Health Foundation, Mary K. Campuzano, Steve Coen, and Marni Vliet, and those from collaborating communities, who continue to teach us about ways to enhance community capacities to address local concerns.     

The Charles Bonnet syndrome: 'phantom visual images'.

The Charles Bonnet syndrome is a condition in which individuals experience complex visual hallucinations without demonstrable psychopathology or disturbance of normal consciousness. An analysis of the sixty-four cases described in the literature reveals that the syndrome can occur at any age though it is more common in elderly people. Reduction in vision, due to peripheral eye pathology as well as pathology within the brain, is associated with the syndrome. Individual hallucinatory episodes can last from a few seconds to most of the day. Episodes can occur for periods of time ranging from days to years, with the hallucinations changing both in frequency and in complexity during this time. The hallucinations may be triggered or stopped by a number of factors which may exert their effect through a general arousal mechanism. People, animals, buildings, and scenery are reported most often. These images may appear static, moving in the visual field, or animated. Emotional reaction to the hallucinations may be positive or negative. Several theories have been proposed to account for the hallucinations. This paper highlights the sensory deprivation framework, with particular emphasis on the activity in the visual system after sensory loss that produces patterns of nerve impulses that, in turn, give rise to visual experience.     

Parental Leave of Absence: Some Not So Family-Friendly Implications1

This experiment examined the effects of ratee gender, type of leave of absence, and level of performance on perceptions of organizational commitment, work commitment, family commitment, and recommendations for organizational rewards. The proposed 3-way interactions between gender, type of leave of absence, and performance level were not supported; however, main effects and 2-way interactions were revealed. Moreover, perceived organizational commitment and work commitment were found to moderate the relationship between performance level and reward recommendations. The findings also indicated that men who were depicted as taking a leave of absence from work for parental reasons were less likely to be recommended for rewards than were males who had not taken a leave of absence.     

Mastery motivation: Appropriate tasks for toddlers

Mastery motivation is the inherent drive which leads young children to explore and master their environment. This research explores the relationship between age and the ability to complete a task, and the appropriateness of using new shapes and mazes to assess mastery motivation in toddlers.     

Character Attacks and Their Effects on Perceptions of Male and Female Political Candidates

The study examined the perceptions of political candidates (male and female) who make negative statements about the personality and integrity of their political opponents. Male and female participants (Sex of Participant factor) indicated their impressions of a male or female political candidate (Sex of Candidate factor) who either attacked or did not attack the character of his/her opponent (Attack factor) in a political leadership debate. Participants who read a speech given by a candidate of their own gender tended to rate the candidate as having greater integrity when the candidate attacked his/her opponent than when he/she did not. When judging a candidate of the opposite gender, participants tended to rate the candidate who attacked his/her opponent as having less integrity than a candidate who did not attack his/her opponent. Results are discussed with regard to the impact that aggressive campaign tactics can have on voter perceptions, and how similarity between voters and candidates may affect perceptions of such tactics.
