Imputation procedures for categorical data: their effects on the goodness-of-fit chi-square statistic

An imputation procedure is a procedure by which each missing value in a data set is replaced (imputed) by an observed value using a predetermined resampling procedure. The distribution of a statistic computed from a data set consisting of observed and imputed values, called a completed data set, is affecwd by the imputation procedure used. In a Monte Carlo experiment, three imputation procedures are compared with respect to the empirical behavior of the goodness-of- fit chi-square statistic computed from a completed data set. The results show that each imputation procedure affects the distribution of the goodness-of-fit chi-square statistic in 3. different manner. However, when the empirical behavior of the goodness-of-fit chi-square statistic is compared u, its appropriate asymptotic distribution, there are no substantial differences between these imputation procedures.     

School context influences the ethnic identity development of immigrant children in middle childhood

The present paper describes a study investigating the ethnic identity development of Latino immigrant children (n = 155) in middle childhood (ages 8–11) in a predominantly White community. The study examined how ethnic identity was related to children's school context. School context was operationalized at the structural level, as the ethnic composition of the teachers and peers, as well as the schools' implicit messages about their valuing of multiculturalism; and the proximal interpersonal level, as children's perceptions of peer discrimination and teacher fairness. Results indicated that both the structural and proximal context predicted children's ethnic label choices, the importance placed on their ethnic identity, the positivity of their ethnic identity, and their American identity.     

An Interview with Ariel Gore and Bee Lavender of Hip Mama

Abstract

Every small, unassuming zine has the potential to be big. Case in point: Hip Mama, a zine that began in the early '90s as Ariel Gore's senior project using a $1,000 student loan and blossomed into a nationally acclaimed alternative parenting resource. Together with Bee Lavender, Gore continues to publish the journal much as she did with that first issue. But today new readers and new technologies are pushing the zine onto the Web and into larger communities. Read all about how a little zine became a giant in this interview with Ariel Gore and Bee Lavender of Hip Mama. Serials Review 2002; 28:159–162.     

Changing Directions in HIV Prevention: The Move Toward a Psychosocial Model

ABSTRACT

Although some HIV prevention programs have been successful in helping gay and bisexual men change their sexual behaviors, rates of HIV infection continue to increase. In an attempt to address this problem, social workers need to move beyond traditional HIV prevention approaches to a psychosocial model of HIV prevention. Based on the work of previous researchers, this approach assumes that a combination of individual, psychological, and social factors contribute to risky sex in gay and bisexual men. Because social workers are trained to view problems from a psychosocial framework, they are already in a position to develop programs incorporating the psychosocial model. This article examines the psychosocial model of HIV prevention and the various psychosocial factors that may contribute to high-risk sexual behavior and concludes with examples of prevention research that have already incorporated the model.
