Basics of qualitative research: Grounded theory procedures and techniques

Emerging adulthood is proposed as a new conception of development for the period from the late teens through the twenties, with a focus on ages 18-25. A theoretical background is presented. Then evidence is provided to support the idea that emerging adulthood is a distinct period demographically, subjectively, and in terms of identity explorations. How emerging adulthood differs from adolescence and young adulthood is explained. Finally, a cultural context for the idea of emerging adulthood is outlined, and it is specified that emerging adulthood exists only in cultures that allow young people a prolonged period of independent role exploration during the late teens and twenties.

Emerging adulthood. A theory of development from the late teens through the twenties.

It is hypothesized that collective efficacy, defined as social cohesion among neighbors combined with their willingness to intervene on behalf of the common good, is linked to reduced violence. This hypothesis was tested on a 1995 survey of 8782 residents of 343 neighborhoods in Chicago, Illinois. Multilevel analyses showed that a measure of collective efficacy yields a high between-neighborhood reliability and is negatively associated with variations in violence, when individual-level characteristics, measurement error, and prior violence are controlled. Associations of concentrated disadvantage and residential instability with violence are largely mediated by collective efficacy.

A Theory of Development From the Late Teens Through the Twenties

So far in this course we have dealt entirely with the evolution of characters that are controlled by simple Mendelian inheritance at a single locus. There are notes on the course website about gametic disequilibrium and how allele frequencies change at two loci simultaneously, but we didn’t discuss them. In every example we’ve considered we’ve imagined that we could understand something about evolution by examining the evolution of a single gene. That’s the domain of classical population genetics. For the next few weeks we’re going to be exploring a field that’s actually older than classical population genetics, although the approach we’ll be taking to it involves the use of population genetic machinery. If you know a little about the history of evolutionary biology, you may know that after the rediscovery of Mendel’s work in 1900 there was a heated debate between the “biometricians” (e.g., Galton and Pearson) and the “Mendelians” (e.g., de Vries, Correns, Bateson, and Morgan). Biometricians asserted that the really important variation in evolution didn’t follow Mendelian rules. Height, weight, skin color, and similar traits seemed to

Using data from the Project on Human Development in Chicago Neighborhoods (PHDCN), we identified a significant inverse association between the variety of youth organizations available at the neighborhood level and adolescents' exposure to community violence. We examined two non-competing explanations for this finding. First, at the individual level, we tested the hypothesis that access to a greater variety of neighborhood youth organizations predicts adolescents' participation in organized community-based activities, which, in turn, protects against community violence exposure. Second, at the neighborhood level, we tested the hypothesis that lower violent crime rates explain the inverse relation between neighborhood youth organization variety and community violence exposure. Our findings supported the latter of these two mechanisms. © 2009 Wiley Periodicals, Inc.

Adolescents' exposure to community violence: are neighborhood youth organizations protective?

Objective. This article describes the use of the Infant-Toddler Home Observation for Measuring the Environment measure (IT-HOME; Caldwell & Bradley, 1984) in large-scale studies with children in the 2nd and 3rd year of life and explores the psychometric properties of several conceptually based subscales created from HOME items. Design. Data from 4 large studies are examined: the 14-month and 24-month waves of the Early Head Start Research and Evaluation Project (Ns = 2,344 and 2,166, respectively), the National Longitudinal Survey of Youth-Child Supplement (N = 2,615), and the NICHD Study of Early Child Care (N = 1,217). In each individual data set, HOME items are grouped conceptually into subscales, and the subscales are analyzed with respect to internal consistency and external validity with later child developmental outcomes. Results. Four subscales were created, corresponding to the categories Parental Warmth, Parental Lack of Hostility, Support of Learning and Literacy, and Parental Verbal Skills. Bi...

The Infant-Toddler HOME in the 2nd and 3rd Years of Life

Recent analyses of menstrual distress have emphasized sociocultural influences. Yet beliefs and attitudes of men—an important socialization force in the lives of women—have received little attention. In the present study, 239 students (156 females and 83 males) from three colleges filled out a survey on expectations for menstrual and premenstrual symptoms, attitudes about mensturation, sources of menstrual-related information, and effects of menstruation upon daily activities. The major findings are as follows: First, although both males and females believed women experience certain cycle-related symptoms, females reported that women experience more severe menstrual and premenstrual symptoms (when compared to intermenstrual ones) than males reported, while males believed women experience more severe menstrual than premenstrual symptoms than females believed. Second, males learned less about menstruation from the majority of possible informational sources and rated most sources as more negative than did the females. Third, males believed that menstruation had more of an effect on women's moods and had a more debilitating effect on women's lives than did females. Fourth, females rated menstruation as more bothersome than did males. Fifth, more males believed their mothers experienced menstrual irritability and moodiness, while more females believed their mothers experienced swelling. The findings are discussed in terms of the role of socialization and the type of information imparted to males and females in America today.
