The Creation of Muhajirat in America: Social Media as a Platform for Crafting Gender-Specific Interventions for the Domestic Radicalization of Women, 5 countries, 1970-2018 (ICPSR 37682)
This study examines the radicalization of Western women to extremist violence, both through the creation of a moral-situational-action risk model and the examination of their responses to various types of online propaganda. The Moral-Situational-Action Risk Model for Extremist Violence (MSA-RMEV) was developed using situational action theory from criminology and violence risk practice literature. The MSA-RMEV revolves around three domains reflective of propensity, mobilization, and capacity building, geared towards providing a violence risk assessment that can assist the intelligence community in preventing future acts of violence.
A sample of women who self-identified as conservative, liberal, and Muslim were exposed to jihadist, alt-right, and alt-left online propaganda. Physiological responses and self-report assessments were recorded. Eye-gaze, pupil dilation, galvanic skin response, heart rate, and facial emotions were documented, along with women's judgment of their emotional, cognitive, and arousal states, while viewing propaganda.
Based on their results, women were categorized as high-risk, medium-risk, or low-risk for violence. Additionally, numerous variables were created to identify participant's beliefs and behavior related to radicalization. Beliefs included religiosity, political affiliation, the presence of moral emotions, sacred values, developmental maturity, and militant thinking. Behaviors included group affiliations, extent of involvement in extremist activities, and presence on social media platforms such as Facebook, Reddit, and Twitter. Demographic variables such as age, marital status, number of children, race, ethnicity, country of origin, and educational status were included.

Dynamic, Graph-Based Risk Assessments for the Detection of Violent Extremist Radicalization Trajectories Using Large Scale Social and Behavioral Data, United States, Canada, United Kingdom, Germany, 1994-2020 (ICPSR 38135)
This project examines the trajectory of radicalization of jihadists and Incels with two broad objectives in mind. First, to develop new integrated computational technology that can mine, monitor, and screen for the occurrence of behaviors associated with dangerously escalating extremism in large heterogenous databases and provide early warnings of individuals or groups on behavioral trajectories toward extremist violence. Second, to harness data science methodologies to enable rapid, semi-automated support for law enforcement analysts and social science researchers to produce structured behavioral indicator profiles from text sources.
The study operated from the premise that being that violent extremists are a rare, complex phenomenon, it is futile to search for a profile of extremism. Rather, it is better to focus on explaining how people come to embrace violent extremism. This path, referred to here as a radicalization trajectory, implies that an arc exists leading the perpetrator from entertaining extremist ideas to action, and that there is a somewhat predictable pathway from a normal, if perhaps angry state, to the perpetration of a violent attack in the name of the ideology. Two teams were combined to analyze radicalization trajectories: data collection and analysis led by Brandeis University and technology development led by Colorado State University (CSU).
The questions revolving around the technological development were as follows: Can tools that rigorously examine and account for the activities of close associates better predict the likelihood that an individual would engage in violent extremism? Which risk assessment indicators for violent extremism in the extant literature are detectable via automated or semi-automated technologies, and what databases and datasets must be integrated to facilitate this detection? Can computationally efficient tools be used to mine these databases for the specific purposes of monitoring and screening for individuals and small groups posing a significant risk for violence?

In this study, researchers used capture-recapture sampling and multiple data sources to gauge the impact of drug trafficking in Quebec, Canada on the United States drug market. The main analyses were based on arrest data that were obtained for Quebec. In addition, analysis of the chemical composition and price assessments of the Quebec synthetic drugs was done.
The study includes one SPSS data file (Quebec Arrest Data (Synthetic Drugs Cases, September 2014; n=20261)-ICPSR.sav ; n=20,261 ; 13 variables) and one Excel data file (Chemical composition of seized synthetic drugs.xls ; n=365 ; 14 variables).
Spatial analyses of border seizure data was performed by the researchers, but these data are not available at this time. The data used for these analyses concerned synthetic drug seizures at Canadian borders from 2007 to 2012. The dataset was provided by the Canadian Border Services Agency (CBSA). For each seizure, the specific border crossing where the seizure was made was provided, as well as the value of the seizure (except for precursors), the country of origin and the type of drug seized. The types of drugs were classified into five types: (1) Precursors, (2) MDMA, (3) Amphetamine, (4) Methamphetamine and (5) Others. Most of the seizures (86.6 percent) were classified in this last category. The country of origin of the seizure was also provided.

This study was designed to understand the economic and social structure of the market for stolen data on-line. This data provides information on the costs of various forms of personal information and cybercrime services, the payment systems used, social organization and structure of the market, and interactions between buyers, sellers, and forum operators. The PIs used this data to assess the economy of stolen data markets, the social organization of participants, and the payment methods and services used.
The study utilized a sample of approximately 1,900 threads generated from 13 web forums, 10 of which used Russian as their primary language and three which used English. These forums were hosted around the world, and acted as online advertising spaces for individuals to sell and buy a range of products. The content of these forums were downloaded and translated from Russian to English to create a purposive, yet convenient sample of threads from each forum.
The collection contains 1 SPSS data file (ICPSR Submission Economic File SPSS.sav) with 39 variables and 13,735 cases and 1 Access data file (Social Network Analysis File Revised 04-11-14.mdb) with a total of 16 data tables and 199 variables.
Qualitative data used to examine the associations and working relationships present between participants at the micro and macro-level are not available at this time.
Gang Affiliation and Radicalization to Violent Extremism within Somali-American Communities, 5 North American Cities, 2013-2019 (ICPSR 37466)
How is the process of radicalization understood over time? Do current radicalization to violence differ from earlier waves? How can these understandings be utilized to prevent radicalization to violence and--equally important--understand the reach and impact of programs designed to do so? The overall goal of this project was to pursue the following aims:
- Aim 1: To understand how adversity and social bonds relate to changes in openness to violent extremism over time.
- Aim 2: To evaluate experience and perception of, and the effectiveness of, Countering Violent Extremism (CVE) activities.
- Aim 3: To evaluate mechanisms of change in violent extremism.
- Aim 4: To understand similarities/ differences in experiences and/or histories of Somali youth who joined Al-Shabab vs. those known to have been killed in Syria, fighting with ISIS and other terrorist groups.
The above aims were accomplished through extending an ongoing longitudinal research program to span 5 years, and expanding a psychological autopsy sample to include Somali youth who have left Minneapolis and been killed fighting with ISIS and other terrorist groups in Syria. Data collection for the longitudinal study consisted of conducting an additional wave of structured interviews with Somali youth (between the ages of 21-33); interviews included assessments of structural adversity (resettlement hardships, trauma exposure, and discrimination), social factors (connection to the resettlement community and/or Somali diaspora community, internet use, and level of acculturation) delinquency, gang involvement, civic engagement, and support for legal and illegal (violent) actions in support of political change. The researchers used latent transition analysis (LTA), generalized estimating equation modeling, and linear regression modeling to accomplish Aims 1-3. Aim 4 was accomplished by using a combination of open source data analysis, psychological autopsy and case analysis methodology. The researchers expanded our current in-depth case studies of Somali youth who left Minneapolis to join al-Shabaab (N = 23, males aged 22-30) to include those who joined ISIS or Al-Nusra (N=4, males aged 18-29). Research questions associated with Aim 4 were analyzed using a psychological autopsy method of developing case histories. Case histories were coded for themes and analyzed for convergence or divergence with case histories of youth who joined Al-Shabab. Scholarly products include manuscripts in journals relevant to criminal justice, policy briefs, and interim and final reports. This project builds on partnerships between Boston Children's Hospital, Somali communities, and Georgia State University.

This study was a three part project which evaluated the procedural aspects of police lineups. The first part was a meta-analysis of existing laboratory data on comparative eyewitness accuracy rates for sequential versus simultaneous lineups. The second part was three experiments on the elements of current field lineup practices in simultaneous and sequential lineups. The third part was a field experiment in Tucson, Arizona, which tested double-blind simultaneous versus double-blind sequential lineups.
Rehabilitation Programs for Adult Offenders: A Meta-Analysis in Support of Guidelines for Effective Practice, 5 Countries, 1950-2014 (ICPSR 37281)
This is a comprehensive meta-analysis of available research on the effects of intervention programs for adult offenders, which is based on 801 eligible controlled studies reported through 2014 identified by researchers. Variables describing the intervention, participating offender samples, research methods, and effects found on a range of outcome constructs were coded into a database for analysis. The major outcome categories examined were recidivism, substance use, employment, mental health, anger/hostility, and aggression/violence. Broad intervention approaches included those such as cognitive behavioral, structured group, counseling, and drug court programs.
The meta-analysis seeks to examine outcomes of various types of interventions and identify the characteristics of programs and participants most closely associated with positive outcomes. It seeks to use the findings to construct and obtain feedback on effective practice guidelines within the adult correctional system.
Research and Evaluation on Domestic Radicalization to Violent Extremism: Research to Support Exit USA, United States, 2015-2019 (ICPSR 37684)
The spread of and involvement in domestic extremist organizations are some of the most pressing issues facing the criminal justice field. There is little research studying the trajectories of former members of extremist organizations. This project begins to address the gaps in knowledge about radicalization and exit by gathering firsthand accounts from former members of white supremacist organizations in the U.S.
The goal of this project was to understand the pathways to disengagement and deradicalization among former white supremacists to provide justice and community organizations with useful information to support prevention and intervention strategies. There is a dearth of systematic information about the motivations, trajectories, and barriers involved with the disengagement and deradicalization process. This project was designed to provide a necessary and foundational assessment of the processes involved with becoming a former extremist. This project charted the social and psychological processes involved in exiting domestic extremist organizations by analyzing the detailed life history accounts of 47 former domestic extremists.
Second International Self-Reported Delinquency Study, 2005-2007 (ICPSR 34658)
The Second International Self-Report Delinquency Study (ISRD-2) was a large international collaborative study of delinquency and victimization of 12 to 15 year-old students in seventh, eighth, and ninth grade classrooms. The study was a school-based study that drew on random samples from either city level or national level. In general, the cross-national description of the prevalence and incidence of delinquent behavior allowed for the assessment of national crime rates by comparison with the crime rates of other countries. The study was conducted in 31 mostly European countries, the United States, Caribbean and South American countries. The primary research questions explored included:
- Is juvenile delinquency normal, ubiquitous, and transitional?
- Is there a pattern of similarity in the offending behavior of juveniles across countries or are there any important differences? Descriptive comparisons of crime rates will call for explanations, especially if differences are observed.
- What are the national socio-economic or cultural differences, or the characteristics of legal or criminal policies that can explain such differences?

Trauma-Focused Interventions for Justice-Involved and At-Risk Youth: A Meta-Analysis, 1980-2015 (ICPSR 37439)
The objective of the Trauma-Focused Interventions for Justice-Involved and At-Risk Youth meta-analysis was to systematically review and statistically synthesize all available research on the effectiveness of trauma-informed treatment programs for justice-involved youth and youth at-risk of justice system involvement who experienced some form of trauma in their lives. A systematic search identified 29 publications that met the eligibility criteria and represented 30 treatment-comparison contrasts. Of these studies, 6 evaluated the effectiveness of trauma-informed programs for justice-involved youth, and the remaining 24 evaluated programs for at-risk children and youth. From these studies, researchers extracted results related to delinquency, problem behaviors, aggression, antisocial behavior, substance use, and post-traumatic stress disorder (PTSD) outcomes. Most of these studies (24) used random assignment to conditions designs, with the remaining 6 using a quasi experimental design with a comparison condition.
Variables in this collection include type of publication, authors, country of study, type of primary study design, publication year, youth type (at-risk or delinquent), frequency and duration of treatment, treatment techniques and types of therapy, treatment and control group sample sizes, as well as variables summarizing respondent histories of abuse, neglect, trauma, violence, delinquency, institutionalization, homelessness, and involvement in foster care. Demographic information on primary study respondents includes overall sample, treatment, and control group percentage breakdowns by ethnicity and respondent age summary statistics.
Understanding Pathways To and Away From Violent Radicalization Among Resettled Somali Refugees, 4 North American cities, 2013-2015 (ICPSR 37449)
Somalis in North America offer a window into the remarkable potential that can be realized by refugees/immigrants despite experiences of severe adversity as well as the challenges some subgroups encounter when adjusting to life in a new country. Somalia has endured one of the longest and most brutal wars of the past 30 years. This enduring conflict has led to millions of Somalis being dispersed as refugees across the globe. As refugees with limited resources, many Somalis in North America are resettled in poor urban neighborhoods where they are visibly different, not only because of race or ethnicity but also because of dress, especially for women who wear a Muslim head covering.
In addition, the community has been plagued by violence. While the number of Somali American youth joining these groups are small and while the majority of Somali Americans are law-abiding citizens, the terrorist groups' ability to recruit these youth and to convince some of them to engage in violent acts is concerning, not only to policymakers and law enforcement, but also to the Somali community, which fears losing more youth to violence or having the community's reputation sullied by being associated with terrorism.
While some of the social and cultural factors affecting Somalis are unique to that ethnic group, they also share experiences common to many immigrants, navigating identity development and duality as they move between home and host cultures, contending with discrimination as religious, racial and ethnic minorities, and striving to achieve their dreams while struggling to gain socioeconomic stability. Thus, understanding their developmental trajectories may inform the understanding of other immigrant and refugee groups as well.
No valid and reliable measurement for risk for violent extremism exists; there is no single profile or set of risk factors that can accurately determine who is most at risk for engaging in violent extremist acts. The study did not attempt to determine who is most at risk. Rather, the researchers sought to identify broad attitudes that would indicate a general openness to, or rejection of, the use of violence or illegal actions in support of a political cause.
The qualitative interviews feature experiences of formal (e.g. police) and informal (e.g. community) institutions over the past year. Examples of interview prompts include questions related to social bonds with family and community, and interactions with police.
