Self-enhancement of Peer Acceptance: Implications for Children's Self-worth and Interpersonal Functioning

Changes in feelings of self‐worth and peer acceptance associated with self‐enhancing perceptions of their peer acceptance were examined for a normative sample and for a group of peer‐rejected children. Whether the correlates of self‐enhancement differed as a function of the way in which perceptions were assessed (i.e., general versus specific measures of self‐enhancement) or by the degree of enhancement were also studied. Using a longitudinal design, 670 students in grades 3 through 5 were assessed across an academic year. For the normative sample, general self‐enhancement of peer acceptance was associated with positive outcomes; specific self‐enhancement of peer acceptance was unrelated to changes in outcomes. Both general and specific self‐enhancement scores were associated with gains in one or more outcome measures in the rejected group. No support was found for the hypothesis that mild to moderate self‐enhancement is predictive of adjustment whereas extreme self‐enhancement is related to maladjustment.     

Acting Autonomously Versus not Acting Heteronomously

This paper presents a formal framework that purports to capture some aspects of Kant's theory of freedom. In particular, we argue that the analysis sheds further light on Kant's distinction between a negative and a positive concept of freedom. The paper shows that the two concepts are not equivalent: we not only argue that in a Kantian perspective negative freedom need not entail positive freedom, but also that there are situations in which a person can be said to be positively but not negatively free (in a Kantian sense).     

The advocate as gatekeeper: The limits of politeness in protective order interviews with Latina survivors of domestic abuse

Within institutions that provide assistance to victims of domestic violence, professionals and volunteers work as advocates for their clients at the same time that they act as gatekeepers for their agencies. While the labor of advocacy consists of empowering clients and validating their concerns and feelings, the task of gatekeeping entails making judgments about them in order to dole out goods and services. Thirty protective order interviews and their resulting affidavits form the data for this study. These interviews take place in a district attorney's office and in a pro bono law clinic. This micro-level analysis of the verbal interaction between protective order application interviewers (both paid and volunteer) and their Latina clients investigates what positive politeness strategies can reveal about how interviewers construct the conflicting discursive identities of advocate and gatekeeper. I examine what interviewers say to clients as well as how interviewers allow clients to give their accounts of abuse. The study points to specific linguistic techniques that may leave victims feeling unaccompanied in the sociolegal system. I suggest that one consequence of the gatekeeping required of interviewers is that victim-survivors may perceive a 'second assault' by the institutions meant to serve them. Linguistic phenomena particular to Latina women in the United States are also brought to light.

The Community Development for Healthy Children Initiative

Abstract

An increasing interest in positive youth development has led to the creation and expansion of programs and initiatives related to youth involvement and engagement. This article focuses on the Community Development for Healthy Children initiative, which envisions making Kansas the best state in the nation in which to raise a child. The initiative includes three primary strategies: A multi-media campaign; technical assistance and support to local communities; and mini-grant opportunities. The paper provides examples of activities from across the state that promote youth involvement. Outcomes across four areas are examined, and the benefits and challenges of this initiative are also discussed.

Young Children's Emotional Attachments to Stories

In the interest of developing a more holistic and integrated understanding of young children's experience of stories, this study describes preschoolers' emotional attachments to stories and the cultural beliefs and practices which surround such attachments. Thirty-two European-American, middle-class families, participated in an interview study of their children's story attachments, and five of these mothers also participated in a short-term, longitudinal diary study. Every child experienced at least two emotional attachments to stories. Children were captivated by stories presented in different media, with many attachments occurring around video stories in addition to books. They expressed their attachments by repeatedly requesting the story, expressing strong feelings, and enacting the story in pretend play. Story attachments were social in two fundamental ways: children created relationships with the characters in their favorite stories, and story attachments emerged in the context of relationships with caregivers whose beliefs and practices supported such attachments.

A family of bivariate binomial distributions generated by extreme bernoulli distributions

In this paper, bivariate binomial distributions generated by extreme bivariate Bernoulli distributions are obtained and studied. Representation of the bivariate binomial distribution generated by a convex combination of extreme bivariate Bernoulli distributions as a mixture of distributions in the class of bivariate binomial distribution generated by extreme bivariate Bernoulli distribution is obtained. A subfamily of bivariate binomial distributions exhibiting the property of positive and negative dependence is constructed. Some results on positive dependence notions as it relates to the bivariate binomial distribution generated by extreme bivariate Bernoulli distribution and a linear combination of such distributions are obtained.
