About the Lab

Professor Jong-min Na's research lab specializes in criminology, criminal justice, and public policy, with a strong focus on youth delinquency, desistance from crime, and the long-term impacts of social and educational interventions. The lab investigates how factors such as self-control, social bonds, school engagement, and co-production in public services shape individual behavior and public safety outcomes. Drawing on longitudinal data and experimental designs, the lab explores the interplay between individual development, institutional responses (e.g., school policing, crisis management), and systemic factors in shaping crime and justice outcomes.

Police Officers in Schools: Effects on School Crime and the Processing of Offending Behaviors
Chongmin Na, Denise C. Gottfredson
SJR Q1Justice Quarterly

The use of police in schools has increased dramatically in the past 12 years, largely due to increases in US Department of Justice funding. This study used data from the School Survey on Crime and Safety to assess the extent to which the addition of police in schools is associated with changes in levels of school crime and schools responses to crime. We found that as schools increase their use of police, they record more crimes involving weapon and drugs and report a higher percentage of their n

CAN SELF‐CONTROL CHANGE SUBSTANTIALLY OVER TIME? RETHINKING THE RELATIONSHIP BETWEEN SELF‐ AND SOCIAL CONTROL*
Chongmin Na, Raymond Paternoster
SJR Q1Criminology

The primary goals of this study were to test the long‐term stability thesis of Gottfredson and Hirschi's (1990) general theory of crime and to examine the relationship between self‐control and social control over time. The data come from a field experiment where the “treatment” consisted of an intentional effort to improve the childrearing behaviors of a sample of caregivers whose children were at high risk of criminal behavior. Caregivers in the control condition were given no such training. Th

Learning From the Past: Distributed Cognition and Crisis Management Capabilities for Tackling COVID-19
Seulki Lee, Jungwon Yeo, Chongmin Na
SJR Q1The American Review of Public AdministrationOA

The outbreak of coronavirus disease 2019 (COVID-19) has presented an unprecedented public health crisis across the globe. Governments have developed different approaches to tackle the complex and intractable challenge, showing variations in their effectiveness and results. South Korea has achieved exceptional performance thus far: It has flattened the curve of new infections and brought the outbreak under control without imposing forceful measures such as lockdowns and travel ban.

The Consequences of School Dropout among Serious Adolescent Offenders
Chongmin Na
SJR Q1Journal of Research in Crime and Delinquency

Objectives: Drawing on labeling and routine activities perspectives, this study investigates whether within-individual change in the school dropout status is associated with the risk of subsequent offending and arrest among serious adolescent offenders. Methods: Longitudinal panel data and a modified version of conventional random-effects models are used as a potential outcome model of causality to directly compare the outcomes before and after the change in the school dropout status. Results: S

Why Citizens Engage in Co-Production: A Theoretical Framework and Experimental Evidence
Seulki Lee, Chongmin Na
SJR Q1Public Performance & Management ReviewOA

Co-production has been embraced as a robust strategy to improve service quality and create public value. Despite growing interest in citizens’ motivations to engage in co-production, there remain some major gaps in the literature. This study proposes a theoretical framework of factors that influence co-production and offers experimental evidence as to the effects of those factors from an online survey experiment with a sample of 1,297 Koreans. The findings show that public service motivation, dr

Prosocial Identities and Youth Violence
Chongmin Na, Ray Paternoster
SJR Q1Journal of Research in Crime and DelinquencyOA

Objective: Despite a recent surge of interest in the important role that identity change plays in the desistance process, much of the empirical work has been qualitative and conducted with small samples, usually of serious adult offenders. Drawing on a nationally representative sample of adolescents in South Korea, this study explores how the development of their prosocial identity is related to their own social bond and network and collectively how this process relates to a downward trend in vi

Learning before and during the COVID-19 outbreak: a comparative analysis of crisis learning in South Korea and the US
Seulki Lee, Jungwon Yeo, Chongmin Na
SJR Q2International Review of Public Administration

© 2020 The Korean Association for Public Administration.Learning is imperative in government responses to crises like the COVID-19 pandemic. This study examines the South Korean and United States governments responses to COVID-19 from a comparative perspective. The analysis focuses on crisis learning conducted before and during the COVID-19 outbreak, using the conceptual categories of intercrisis/intracrisis learning and single-/double-loop learning. The findings suggest that double-loop, interc

Public Service Motivation and Job Satisfaction Amid COVID-19: Exploring the Effects of Work Environment Changes
Seulki Lee, Chongmin Na
SJR Q1Public Personnel ManagementOA

The COVID-19 pandemic has brought critical changes to job demands and resources, which in turn affect employee motivation and outcomes. This study explores how COVID-19–induced work intensity and COVID-19–related organizational support influence public service motivation (PSM) and job satisfaction. Using survey data from a nationally representative sample of 1,430 South Korean central government employees collected during the pandemic (May–June 2020), we find that COVID-19–induced work intensity

Evaluation of Random Forest in Crime Prediction: Comparing Three-Layered Random Forest and Logistic Regression

SJR Q1Deviant Behavior

This study evaluated random forest’s accuracy in predicting violent or criminal behavior of juveniles compared to that of conventional logistic regression using different sets of risk factors. Drawing on the National Longitudinal Study of Adolescent Health (Add Health), we predicted three outcomes – arrests, convictions, and incarcerations – using three sets of predictors, starting with sociodemographic variables only (Model 1) and incrementally adding behavioral/situational (Model 2) and emotio

Police Effectiveness and Procedural Justice as Competing Public Values: Moving Beyond the Instrumental-Versus-Normative Model of Police Legitimacy
Chongmin Na, Seulki Lee, Inkyu Kang
SJR Q1Policing A Journal of Policy and PracticeOA

Abstract This study argues that the dichotomy of instrumental-versus-normative motives in mainstream policing literature can mislead the ways in which police effectiveness and procedural justice shape people’s judgments about the police. Effective policing may be important even for individuals who do not directly benefit from it, while procedurally just policing can bring instrumental benefits, particularly for underprivileged social groups. We propose an alternative framework that characterizes
