Ferguson, K. M., Bender, K., Thompson,S.J., Maccio, E.M., and Pollio, D. (2012). Employment status and income generation among homeless young adults: Results From a five-city, mixed-methods study. Youth & Society, 44. 385-407.
This mixed-methods study identified correlates of unemployment among homeless young adults in five cities. Two hundred thirty-eight homeless young people from Los Angeles (n = 50), Austin (n = 50), Denver (n = 50), New Orleans (n = 50), and St. Louis (n = 38) were recruited using comparable sampling strategies. Multivariate logistic regression results indicate that homeless young adults were more likely to be unemployed if they had been on the streets longer, currently lived on the streets, earned an income from panhandling, and were addicted to drugs. Quantitative findings are expanded on with focus-group data from a group of homeless young people in Los Angeles regarding their challenges in locating and maintaining employment. Employment-related barriers for this population include prior homelessness, geographic transience, previous felonies, mental illness, and addiction. Findings suggest that homeless young adults’ employment status and use of specific income-generating activities may be influenced by demographic, environmental, and geographic contexts.

Bail, C. (2008). The configuration of symbolic boundaries against immigrants in Europe. American Sociological Review, 73(1). 37-59.
Recent studies report significant cross-national variation in the conceptual distinctions or “symbolic boundaries” used by majority groups to construct notions of “us” and “them.” Because this literature compares only a handful of countries, the macro-level forces by which certain symbolic boundaries become more salient than others remain poorly understood. This article provides the first panorama of these processes by comparing the relative salience or “configuration” of multiple symbolic boundaries in 21 European countries. I use fuzzy-set analyses of data from the 2003 European Social Survey to create a typology of symbolic boundary configurations. The results indicate that the symbolic boundaries deployed by the general public do not correspond to the official “philosophies of integration” emphasized in the literature. Moreover, the data suggest previous comparisons have focused too heavily on Western Europe, overlooking important variation in other regions of Europe where immigration began more recently. I generate hypotheses to explain this newfound variation using demographic, socioeconomic, institutional, and historical data from quantitative and qualitative sources. The article concludes with examples of how these hypotheses can be combined by future studies toward a theory of “boundary-work.”

Budig, M. and Hodges, M. (2010). Differences in disadvantage: Variation in the motherhood penalty across white women's earnings distribution. American Sociological Review, 75(5). 705-728.
Earnings inequality has grown in recent decades in the United States, yet research investigating the motherhood wage penalty has not fully considered how the penalty itself, and the mechanisms producing it, may vary among low-wage, middle-wage, and high-wage workers. Pooling data from the 1979 to 2004 waves of the NLSY and using simultaneous quantile regression methods with fixed effects, we test whether the size of the motherhood penalty differs across the distribution of white women’s earnings, and whether the mechanisms explaining this penalty vary by earnings level. Results show that having children inflicts the largest penalty on low-wage women, proportionately, although a significant motherhood penalty persists at all earnings levels. We also find that the mechanisms creating the motherhood penalty vary by earnings level. Family resources, work effort, and compensating differentials account for a greater portion of the penalty among low earners. Among highly paid women, by contrast, the motherhood penalty is significantly smaller and largely explained by lost human capital due to childbearing. Our findings show that estimates of average motherhood penalties obscure the compounded disadvantage mothers face at the bottom of the earnings distribution, as well as differences in the type and strength of mechanisms that produce the penalty.

“Sampling Error.” Encyclopedia of Social Science Research Methods. (2004): 992-993.
Any attempt to use a sample survey as a means of studying a larger population of interest runs the risk that the selected sample will not have exactly the same characteristics as the population. In consequence, sample-based estimates will not necessarily take the same numeric values as the population parameters of which they are estimates. The term sampling error is used to refer to this general tendency of sample estimates to differ from the true population values. A main aim of sample design is to minimize the risk of sample characteristics differing greatly from population characteristics.
