Protest Records,Data Validity,and the Mexican Media: Development and Assessment of a Keyword Search Protocol

While considerable attention has been focused in recent years on questions of selection and coverage biases in media-derived protest data, little has been said about the procedures used to sample media records and scant attention has been paid to non-English-language news sources. This article outlines a Spanish-language keyword search protocol for finding protest event articles, and systematically evaluates it in terms of search validity and efficiency using a two-year dataset constructed from a full-text article search of the Mexican national news agency Noticias de Mexico. Results suggest that this protocol generates data with a high degree of search validity with respect to locating reports of conventional protest event forms, but is problematic with respect to the identification of unconventional protest forms. The significance of these findings for the broader investigation of media-derived protest data is discussed, and directions for future research are outlined.     

LEARNING TO FORECAST PRICE

We study learning in an individual choice price forecasting task in which subjects must learn coefficients of two independent variables in stationary linear stochastic processes. The 99 subjects each forecast in 480 trials with feedback. Learning is tracked by fitting individual forecasts to the independent variables. Results: (1) Learning is fairly consistent with respect to objective values, but with slight tendency toward overresponse. (2) Learning is noticeably slower than the Marcet-Sargent ideal. Two striking treatment effects are tendencies toward (3) overresponse with high background noise and (4) underresponse with asymmetric coefficients.     

Building the next generation of leaders in the disabilities movement

The results from this study highlight ways that the disabilities community within the USA can begin to further promote the numbers and qualities of its leaders. Twenty-one grassroots and statewide leaders of the disabilities movement in one state described how they became a leader and identified ways that the disabilities movement can more effectively promote leadership within its ranks. Overall, our informants highlighted the need for the disabilities movement to re-examine its current definitions of and approaches to leadership development. They described the need for a more collective, versus individualistic, approach to leadership within the disabilities movement and the adoption of a more integrated, action learning approach to leadership development. Implications for the disabilities movement are discussed.     

Children as Research Subjects: a Risky Enterprise

This paper is based on a qualitative research study, Children, Parents and Risk. This study looks at the ways in which risks to children are understood and managed by children and parents. The paper focuses on two areas of the research—gaining access and interviewing—in order to show how the research process itself has constituted an important source of data on childhood and risk.     

Behavior problems in children raised by grandmothers: The role of caregiver distress, family resources, and the home environment

Over the past few decades there has been a dramatic increase in children being raised by grandparents due to a variety of factors including child maltreatment, parental abandonment, substance abuse, and incarceration. The purpose of this study is to examine the extent of behavior problems in children being raised by grandmothers and to determine factors in their current environment that are related to child behavior problems. The study draws on McCubbin's resiliency model of family stress, adjustment and adaptation.The sample comprised of 230 children ages 2 to 16 years who were being raised by grandmothers in parent-absent homes. The families were predominantly low income and African American. The grandmothers ranged in age from 37 to 80 years. Grandmothers responded to several self-report measures pertaining to child behavior problems, family resources, social support, and caregiver psychological distress. Trained research assistants completed a standardized observational measure of the home environment.Results indicated that 31.3% of child participants scored in the clinically elevated range for total behavior problems, with 21.3% and 32.6% scoring in the elevated range for internalizing and externalizing behaviors, respectively. Hierarchical regression analyses revealed that of the variables examined, increased psychological distress in grandmothers was most predictive of child behavior problems, followed by less supportive home environments and fewer family resources.Results of the present study underscore the need for interventions that focus on reducing child behavior problems, as well as enhancing the parenting skills of grandmothers raising grandchildren. Findings also support the need for strategies to reduce stress in grandmother caregivers and to improve access to resources needed to provide supportive home environments for their grandchildren.     

Saving,dependency and development

The widely-observed finding in the literature showing little or no relationship between population growth (and dependency) and saving requires modification based on panel and cross-section estimation of aggregate country data. While such a relationship is still weak in the hybrid Leff-type model, it is now found consistently over time and by stage of development in the Mason variable-growth life-cycle framework, where changes in demographic factors account for a notable part of saving.     

Factors Associated With Growth in Daily Smoking Among Indigenous Adolescents

North American Indigenous adolescents smoke earlier, smoke more, and are more likely to become regular smokers as adults than youth from any other ethnic group, yet we know very little about their early smoking trajectories. We use multilevel growth modeling across five waves of data from Indigenous adolescents (aged 10–13 years at Wave 1) to investigate factors associated with becoming a daily smoker. Several factors, including number of peers who smoked at Wave 1 and meeting diagnostic criteria for major depressive episode and conduct disorder, were associated with early daily smoking. Only age and increases in the number of smoking peers were associated with increased odds of becoming a daily smoker.
