... The Youth Participatory Politics Survey Project (YPPSP) includes questions that examined the quantity, quality, and equality of youth new media practices; as well as political and civic attitudes, behavior, and engagement (collectively referred to as "participatory politics"). The study was conducted in three waves between 2011 and 2015, and this dataset includes respondents who completed both second and third waves (2013 and 2015, respectively). A total of 1,033 respondents, who were between the ages of 15 and 27 in 2013, completed both waves. The wave 2 survey collected data from 2,343 respondents ages 15-27. The survey was administered from July 2013 to November 2013 and June 2015 to November 2015 by the survey vendor Growth from Knowledge (GfK) Group. The 2013 survey was administered online and by telephone, and the 2015 survey was administered online. The survey included oversamples of African Americans, Asian Americans, and Latino respondents. The survey asked questions about political and civic attitudes, media practices, community involvement, political engagement, news sources, and social influences.

... This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a survey on the topic of Contingent Employment in the United States, which was administered as a supplement to the February 2017 CPS. In addition to administering the basic CPS, interviewers asked the supplementary questions in three-fourths of the sample households. The CPS, administered monthly, is a labor force survey providing current estimates of the economic status and activities of the population of the United States, for the week prior to the survey. Specifically, the CPS provides estimates of total employment (both farm and nonfarm), nonfarm self- employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. The Contingent Work Supplement questions were asked of all applicable persons age 16 years and older. The supplement data is comprised of information on contingent or temporary work that a person did without expecting continuing employment from the particular employer they happened to be working for. Also included is information about each worker's expectation of continuing employment, satisfaction with their current employment arrangement, current job history, transition into the current employment arrangement, search for other employment, employee benefits, and earnings. The supplement questions were not asked of unpaid family workers and persons not looking for work (this includes persons not in the labor force and unemployed persons on layoff who are not looking for work). Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, occupation, and income.

The qualitative data are not available as part of the data collection at this time. Numerous high-profile events involving student victimization on school buses have raised critical questions regarding the safety of school-based transportation for children, the efforts taken by school districts to protect students on buses, and the most effective transportation-based behavioral management strategies for reducing misconduct. To address these questions, a national web-based survey was administered to public school district-level transportation officials throughout the United States to assess the prevalence of misconduct on buses, identify strategies to address misconduct, and describe effective ways to reduce student misbehavior on buses. Telephone interviews were also conducted with a small group of transportation officials to understand the challenges of transportation-based behavioral management, to determine successful strategies to create safe and positive school bus environments, and to identify data-driven approaches for tracking and assessing disciplinary referrals. The collection includes 10 Stata data files: BVSBS_analysis file.dta (n=2,595; 1058 variables) Title Crosswalk File.dta (n=2,594; 3 variables) Lessons Learned and Open Dummies.dta (n=1,543; 200 variables) CCD dataset.dta (n=12,494; 89 variables) BVSB_REGION.dta (n=4; 3 variables) BVSB_SCHOOLS.dta (n=3; 3 variables) BVSB_STUDENTS.dta (n=3; 3 variables) BVSB_URBAN.dta (n=8; 3 variables) BVSB_WHITE.dta (n=3; 3 variables) FINALRAKER.dta (n=2,595; 2 variables)

This study presents a research-informed approach to identify the most efficient practices for addressing un-submitted sexual assault kits (SAKs) that accrue in U.S. law enforcement agencies (LEAs) as well as untested SAKs pending analysis in crime laboratories. The study examined intra- and interagency dynamics associated with SAK processing efficiency in a linked sample of crime laboratories. SAK outputs and inputs were assessed for laboratories that conduct biological forensic analysis and LEAs that submit SAK evidence to these laboratories. Production functions were estimated to examine effects of labor and capital inputs, in addition to policies, management systems, and cross-agency coordination on efficiency. Six jurisdictions were recruited for site visits, and qualitative methods were used to understand how LEAs, laboratories, and prosecutors implement practices that affect efficiency. This study contains 7 data files including: Crime Lab_Raw.dta (n=147; variables =242) Crosswalk File.dta (n=2337; variables=2) lab_analysis_sample_2017-04-06.dta (n=132; variables=92) LEA Communication LCAs.dta (n=321; variables=15 merged_analysis_file_JH2017-04-30.dta (n=273; variables=117) policy Class probabilities_LABS.dta (n=139; variables=19) SAK LAB COMMUNICATION LCA.dta (n=134; variables=15)

This study examined differences in youth's mental health and substance abuse needs in seven different racial/ethnic groups of justice-involved youth. Using de-identified data from the Survey of Youth in Residential Placement (SYRP), it was assessed whether differences in mental health and substance abuse needs and services existed in a racially/ethnically diverse sample of youth in custody. Data came from a nationally representative sample of 7,073 youth in residential placements across 36 states, representing five program types. An examination of the extent to which there were racial/ethnic disparities in the delivery of services in relation to need was also conducted. This examination included assessing the differences in substance-related problems, availability of substance services, and receipt of substance-specific counseling. One SAS data file (syrp2017.sas7bdat) is included as part of this collection and has 138 variables for 7073 cases, with demographic variables on youth age, sex, race and ethnicity. Also included as part of the data collection are two SAS Program (syntax) files for use in secondary analysis of youth mental health and substance use.

... The Panel Study of Entrepreneurial Dynamics (PSED) research program was designed to longitudinally examine the startup process with multi-year cohort tracking, so as to enhance the scientific understanding of how individuals start businesses. The project provided data on the process of business formation based on nationally-representative samples of nascent entrepreneurs, those active in business creation. PSED I (available from ICPSR as study 37203) began with screening in 1998-2000 to select a cohort of 830 with three follow-up interviews. The panel participants were identified prior to launch of their firms and were tracked through gestation, launch and eventual growth or death of the firm. A control group of those not involved in firm creation were available for comparisons. PSED II began with screening in 2005-2006, followed by six yearly interviews. The information obtained as part of the PSED research program included data on the nature of those active as nascent entrepreneurs, the activities undertaken during the start-up process, and the characteristics of start-up efforts that become new firms. The PSED II data included as part of this collection includes: Dataset 1 and 2: Screener Data (58 variables, 31,845 cases) Dataset 3 and 4: Waves A-F plus Screener Data (7,821 variables, 1,214 cases) Demographic variables included as part of this collection comprises age, race, ethnicity, gender, household income, educational attainment, employment status, marital status, citizenship, household characteristics, and business characteristics.

... The Tsogolo La Thanzi (TLT): Biomarker collection contains data collected as part of the Tsogolo la Thanzi (TLT) Study. TLT is a longitudinal study in Balaka, Malawi designed to examine how young people navigate reproduction in an AIDS epidemic. Tsogolo la Thanzi means "Healthy Futures" in Chichewa, Malawi's most widely spoken language. New data is being collected to develop better understandings of the reproductive goals and behavior of young adults in Malawi -- the first cohort to never have experienced life without AIDS. To understand these patterns of family formation in a rapidly changing setting, TLT used the following approach: an intensive longitudinal design where respondents are interviewed every fourth months at TLT's centralized research center. Data collection began in May of 2009 and was completed in June of 2012. To assess changes on a longer time-horizon, a follow-up survey referred to as Tsologo la Thanzi 2 (TLT-2) was fielded between June and August of 2016. The biomarker data collection contains the results of HIV testing and pregnancy testing. These data sets include respondents from all waves.

Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed. This collection features secondary analyses of restricted-use data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), a nationally representative longitudinal study of a sample of U.S. adolescents who were in grades 7-12 in the 1994-95 school year, who were interviewed at three key developmental junctures from adolescence to young adulthood. Self-reported data were used for both maltreatment (measured at the latter two time points) and delinquent or criminal behaviors (measured at all three time points). Linear mixed-effects analyses were used to model growth curves of the frequency of violent and non-violent offending, from ages 13 to 30. Next, maltreatment frequency was tested as a predictor, and then potential protective factors (at peer, family, school, and neighborhood levels) were tested as moderators. Sex, race/ethnicity, and sexual orientation were also tested as moderators of delinquent or criminal offense frequency, and as moderators of protective effects. The study collection includes 1 Stata (.do) syntax file (AddHealthOJJDPAnalysis_StataSyntax.do) that was used by the researcher in secondary analyses of restricted-use data. The restricted archival data from the Add Health survey series are not included as part of this release.
