Correlates of Male Adolescents Carrying Handguns Among Their Peers

Data from the National Longitudinal Survey of Youth 1997 were used to examine factors associated with carrying a handgun among adolescent males. We expected that carrying a handgun would be associated with characteristics of the individual and with aspects of the contexts that are important for adolescents, such as the family, the peer group, the school setting, and the neighborhood. Consistent with these expectations, we found that adolescent males were more likely than their peers to carry handguns if they engaged in other problematic behaviors, had witnessed someone else being shot or shot at, and were involved in gangs. Boys under the age of 15 were less likely to carry a handgun if they were closely monitored by their mothers and respected their mothers, and they were more likely to carry a handgun if they frequently heard gunshots in their neighborhood or had a relative or friend who was a gang member. Males who were 15 and older were more likely to carry a handgun if they associated with peers who engaged in problematic behaviors.     

Confidence intervals for nonparametric quantile regression: an emphasis on smoothing splines approach

In this paper we consider the problem of constructing confidence intervals for nonparametric quantile regression with an emphasis on smoothing splines. The mean‐based approaches for smoothing splines of Wahba (1983) and Nychka (1988) may not be efficient for constructing confidence intervals for the underlying function when the observed data are non‐Gaussian distributed, for instance if they are skewed or heavy‐tailed. This paper proposes a method of constructing confidence intervals for the unknown τth quantile function (0<τ<1) based on smoothing splines. In this paper we investigate the extent to which the proposed estimator provides the desired coverage probability. In addition, an improvement based on a local smoothing parameter that provides more uniform pointwise coverage is developed. The results from numerical studies including a simulation study and real data analysis demonstrate the promising empirical properties of the proposed approach.     

Warriors in suits: A Bourdieusian perspective on the construction and practice of military masculinity of Korean men

Within masculinity scholarship, there is a gap about how masculinity carries over from a broad social context to an organizational context. This article explores the construction and capitalization of masculinity through a series of experiences in social fields such as the military and college, and the transfer of militaristic masculinity into the workplace. Drawing on grounded theory methods, we conducted in‐depth interviews with 20 Korean men who completed their mandatory two‐year military service and subsequently joined large corporations in Korea. We uncovered a four‐phase model that depicts how Korean men's masculinity is constructed during military service and transferred to their organizational positions characterizing them as warriors in suits. Informed by a Bourdieusian perspective, this study shows how masculinities are constructed, reinforced and legitimatized by the structural influences of society, and how masculinity becomes the desired image of men at work, which perpetuates the gender and power gaps among organizational members.     

The Tasks and Characteristics of Supportive Support Brokers

ABSTRACT

In the United States, under the Cash and Counseling or budget authority model of self-directed personal assistance where the participant manages his or her own services and supports, the Support Broker role was established to assist and coach the participant. The support broker role grew out of a person-centered planning process where focus groups and surveys helped ascertain what potential participants wanted to help them establish a self-directed alternative. But, despite this role being described in policy guidance from the Center for Medicare and Medicaid, little research has been conducted examining the functions, activities and usefulness of this position. This study draws on 76 ethnographic case studies with early Cash and Counseling participants, examines what participants and their caregivers actually saw the support broker doing, and looks at what the participants found helpful and less than helpful. Participants and family caregivers saw support broker duties as falling into four areas: Coaching, Problem Solving, Advocacy and Monitoring. Equally important was how the support broker performed these duties. Key aspects of quality included: Familiarity, Supportive Relationship, Proactive Engagement, Responsiveness, Knowledge and Cultural Friendliness. These findings can provide the basis for establishing quality indicators for self-direction.     

“Racist Propaganda”: discursive Negotiations on YouTube of Perceived Anti-White Racism in South Korea

This article analyzes YouTube comments about a Munhwa Broadcasting Company report that White “expatriates” in South Korea called xenophobic and racist. The research is important because there is a paucity of scholarship on White discourse outside the West and because there is limited work on YouTube as a space to articulate and negotiate discourses about racism. This is despite the increasingly complex flows of people and discourse around the globe. In this article, I argue that YouTube acted as a site of ideological negotiation in which Orientalist discourses were advanced under the cover of color-blind racism. Many of the YouTube comments framed Korea as xenophobic and racist, and even for self-identified White commenters sympathetic to the report, they did not challenge the construction of Korea as racist or the normative belief in postracism.     

Bayesian inference and model selection in latent class logit models with parameter constraints: an application to market segmentation

Latent class models have recently drawn considerable attention among many researchers and practitioners as a class of useful tools for capturing heterogeneity across different segments in a target market or population. In this paper, we consider a latent class logit model with parameter constraints and deal with two important issues in the latent class models--parameter estimation and selection of an appropriate number of classes--within a Bayesian framework. A simple Gibbs sampling algorithm is proposed for sample generation from the posterior distribution of unknown parameters. Using the Gibbs output, we propose a method for determining an appropriate number of the latent classes. A real-world marketing example as an application for market segmentation is provided to illustrate the proposed method.     

Bayesian Estimation of the Two-Parameter Gamma Distribution

In this article, we present and discuss an original price index being a special case of a general formula for price indices. We show that the discussed formula satisfies most postulates coming from the axiomatic price index theory. We compare this index to other known and popular price indices in a simulation study.     

A local linear estimation of conditional hazard function in censored data

A local linear estimator of the conditional hazard function in censored data is proposed. The estimator suggested in this paper is motivated by the ideas of Fan, Yao, and Tong (1996) and Kim, Bae, Choi, and Park (2005). The asymptotic distribution of the proposed estimator is derived, and some numerical results are also provided.     

The Role of Heritage Language Development in the Ethnic Identity and Family Relationships of Adolescents from Immigrant Backgrounds

The influence of immigrant-background adolescents' heritage language (HL) proficiency and use of the language on parent–adolescent relationships and ethnic identity was investigated in a sample of 414 adolescents from Latin American and Asian backgrounds. HL proficiency, but not language use, was positively associated with the quality of parent–adolescent relationships. Although HL proficiency and language use were both associated with ethnic identity, when taken together, only HL proficiency was a reliable predictor. These findings indicate that it is the development of proficiency in the HL that influences adolescents' successful adjustment, rather than their choice of languages. It is therefore important to support HL development in order to help immigrant-background students to better cope with the stresses of adolescence.     

Stemming inequality? Employment and pay of female and minority scientists and engineers

When white men overwhelmingly dominated the science, technology, engineering, and mathematics (STEM) work force, the high pay in STEM occupations was a major source of gender and race inequality in the U.S. economy. As women, Blacks, and Latinos increasingly study STEM fields, new possibilities for achieving pay equality are opening. We test whether the reality matches the promise using two large data sets. Analysis of a five percent Public Use Microdata Sample (PUMS) of the 2000 Census and the 2001-06 American Community Surveys shows that women and minorities earn more, relative to comparable white men, in STEM than in non-STEM fields. This general pattern persists in analysis of a 1% sample of federal personnel records, which include better measures of work experience and education. Thus, federal efforts to increase the representativeness of the STEM workforce should increase pay equality in the economy by moving women and minorities into traditionally high-paying fields.
