To what extent can anti-corruption measures serve to limit patronage and corrupt networks effectively and sustainably in clientelist societies with a prevailing norm of corruption? We develop a political agency model in which office holders are motivated to reduce rent seeking behavior through re-election incentives operating via elections and audits (formal institutions), but also through reputational or self-image concerns that are influenced by the prevailing norm on corruption in their peer group (informal institutions). We show that, while the formal institutions of audits and elections have the desired direct effect of reducing corruption, they also affect informal rules of conduct, which can have unintended effects. In particular, in clientelist societies with high levels of corruption, the social concerns work in opposition to formal incentives provided by anti-corruption efforts. Applying the theory to data from Puerto Rico’s anti-corruption municipal audits program, we find evidence consistent with the idea that anticorruption measures are less effective due to social spillovers.

Background

Illicitly manufactured fentanyl (IMF) increases overdose mortality, but its role in infectious disease transmission is unknown. We examined whether IMF use predicts hepatitis C virus (HCV) and human immunodeficiency virus (HIV) incidence among a cohort of people who inject drugs (PWID) in San Diego, California and Tijuana, Mexico.

Methods

PWID were recruited during 2020–2022, undergoing semi-annual interviewer-administered surveys and HIV and HCV serological rapid tests through 2024. Cox regression was conducted to examine predictors of seroconversion considering self-reported IMF use as a 6-month lagged, time-dependent covariate.

Results

Of 398 PWID at baseline, 67% resided in San Diego, 70% were male, median age was 43 years, 42% reported receptive needle sharing, and 25% reported using IMF. HCV incidence was 14.26 per 100 person-years (95% confidence interval [CI]: 11.49–17.02), and HIV incidence was 1.29 (95% CI: .49–2.10). IMF was associated with HCV seroconversion, with a univariable hazard ratio (HR) of 1.64 (95% CI: 1.09–2.40), and multivariable HR of 1.57 (95% CI: 1.03–2.40). The direction of the relationship with HIV was similar, albeit not significant (HR 2.39; 95% CI: .66–8.64).

Conclusions

We document a novel association between IMF and HCV seroconversion among PWID in Tijuana–San Diego. Few HIV seroconversions (n = 10) precluded our ability to assess if a similar relationship held for HIV. IMF's short half-life may destabilize PWID—increasing the need for repeat dosing and sharing smoking materials and syringes. New preventive care approaches may reduce HCV transmission in the fentanyl era.

An agent-based model is a form of complex systems model that is capable of simulating how the micro-level behavior of individual system entities contributes to macro-level system outcomes. Researchers draw on theory and evidence to identify the key elements of a given system and specify behaviors of agents that simulate the individual entities of that system—be they cells, animals, or people. The model is then used to run simulations in which agents interact with one another and the resulting outcomes are observed. These models enable researchers to explore proposed causal explanations of real-world outcomes, experiment with the impacts that potential interventions might have on system behavior, or generate counterfactual scenarios against which real-world events can be compared. In this review, we discuss the application of agent-based modeling within the field of criminology as well as key challenges and future directions for research.

Criminology is haunted by state-structured biases. We discuss five. (a) With the spatial boundaries and the binary deontology they use to count crime, governments draw researchers into ecological fog and sometimes fallacy. (b) All legal systems encourage criminologists to promote untenable implications of socially stratified criminality. (c) To degrees that vary by time and place, the scope of criminological research is compromised by methodological nationalism. (d) State agencies use chronologies that repeatedly draw researchers away from examining the nonlinear temporalities that shape variations in criminal behavior. (e) State agencies produce data that facilitate explaining the why of crime, but scientific naturalism would first work out what is to be explained. We recommend a criminology that begins by describing causal contingencies in social life independent of governments’ labeling of crime.

My interest in criminology grew as the Vietnam War escalated. I applied to two Canadian graduate schools and flipped a coin. The coin recommended the University of Toronto, but I chose the University of Alberta, which had a stronger criminology program. I wrote a dissertation about criminal sentencing, which led to an Assistant Professorship at the University of Toronto. Dean Robert Pritchard of Toronto’s Law School encouraged my work and later successfully nominated me for a Distinguished University Professorship. My interests continued to grow in international criminal law. A MacArthur Distinguished Professorship at Chicago’s Northwestern University and the American Bar Foundation facilitated my research at the Tribunal for the Former Yugoslavia. I followed this by studying the crime of genocide in Sudan and later the trial of Chicago’s Detective Jon Burge. Burge oversaw the torture of more than 100 Black men on Chicago’s South Side. US Attorney Patrick Fitzgerald prosecuted Burge when Illinois prosecutors would not. Despite many good things about Chicago, the periodic corruption of the government and police was not among them.

The goal of this process evaluation was to determine how closely the RRC was following evidence-based practices for reentry and to determine how successful the RRC has been transitioning individuals from the jail to the community. To evaluate the effectiveness of the RRC, we (1) conducted a survey of county staff involved in the reentry process (n = 25) to better understand how staff perceive the reentry planning process and the RRC, (2) conducted observations of the intake and screening process at the MDC, and (3) reviewed client records for all inmates who passed through the RRC between 2018 and 2022. We found that there were challenges associated with how the RRC screened, assessed, and targeted individuals for intervention related to a lack of standardization across process components. Surveys collected from staff members provided insight into challenges related to reentry, such as the need for a single case plan to follow the individual through jail and into the community. Finally, analysis of the client-level data illustrated the services and needs of clients. While many individuals (n = 9,985) completed risk needs assessments (RNAs), the number of individuals that completed transition plans (TPs) is far less (n = 2,785). Due to the nature of the different challenges of the current process in place, determining the impact of the RRC on recidivism reduction remains complicated.

This study evaluates the predictive validity of the Public Safety Assessment (PSA) in Bernalillo County, New Mexico, using data from 22,387 felony cases between July 2017 and June 2023. The PSA, which generates scores predicting defendants' likelihood of failure to appear (FTA), new criminal activity (NCA), and new violent criminal activity (NVCA) during pretrial release, demonstrated "fair" to "good" predictive validity with AUC scores ranging from 0.58-0.69, aligning with results from our initial validation study from June 2021. While the PSA showed similar predictive performance across racial groups for FTA and NCA outcomes, the NVCA flag performed poorly for Black defendants, with predictive validity no better than chance. We also found that age-related risk factors embedded in the NCA and NVCA scales had limited predictive value. We documented significant increases in FTA rates during and after COVID-19, likely due to policy changes that increased court appearances through mandatory status hearings. Despite higher base rates of NCA and NVCA for male defendants, the PSA demonstrated similar predictive validity across genders. Analysis of NCA by charge severity revealed that even high-risk defendants rarely committed serious felonies while on pretrial release. Our findings suggest opportunities to optimize the PSA locally by adjusting how age-related factors are weighted and reconsidering the use of the NVCA flag for Black defendants.

The Department of Health, Housing, and Homelessness (HHH) launched the Albuquerque Peer to Peer: Opioid Coordination and Outreach Project in September 2017. The project aims to reduce opioid misuse, overdose, and death in the Albuquerque area by using peer support workers to connect individuals suffering from opioid use disorder with appropriate treatment and recovery support services. This report presents the results of CARA’s evaluation of the Peer to Peer project. We review the scientific literature on similar programs to establish a baseline for expected client outcomes and best practices, and then compare the Peer to Peer project to this baseline through an analysis of program documents and service data. The results of our analysis reveal that Albuquerque Peer to Peer is broadly designed and implemented according to best practices. However, we recommend clarifying the procedures for assessing client needs and facilitating client engagement in referred-to services. In terms of the short-term outcome -- proportion of clients who engaged in the treatment services to which they were referred – we found that Albuquerque Peer to Peer is performing as well as comparable, state-of-the-art peer outreach programs. We recommend the project track middle to long-term client outcomes, like rates of EMS involvement and overdose death, moving forward.

This report explores the utility of using Vermont criminal histories to understand probation and parole violations. We conclude that criminal histories alone are not sufficient to understand the dynamics of probation and parole violations. Intensive Department of Corrections (DOC) resources would be needed to better understand the when, where, and what of violations. Methods We used two data sources to identify who was released on probation or parole. For parole releases we used the National Corrections Reporting Program (NCRP) report that is generated by the Vermont Department of Corrections and submitted to the federal government. This report is an offender-level report that captures entries and releases from correctional facilities. We used the reports that captured Federal Fiscal Year data from 2016, 2017, and 2018. We used this dataset to identify people who were released from facilities and therefore might have been placed on parole. We requested their Vermont criminal histories and identified if/when they were released on parole. They became our parole cohort. The probation cohort was generated from the Court Adjudication Database maintained by Crime Research Group (CRG). We selected people who were sentenced to probation or deferred sentences (which is also a probationary sentence) for the probation cohort. We had to exclude people sentenced to a split sentence. A split sentence is a type of sentence that is split between incarceration in a facility and then a subsequent period of time on probation. We did not include these people because we could not accurately identify when someone was released from a correctional facility to probation. In the NCRP data, the release could be the initial release or release from an incarceration due to a probation violation. The criminal histories no longer capture when someone is released on probation. The final cohort for probation, deferred, and parole are described below in Table 1. As is often the case with criminal justice data in Vermont, there were too few people of Asian, Indigenous, and Hispanic descent to provide detailed numbers without the possibility of someone being identified

Identity or self-concept has long been theorized to explain rule-violating behavior. Life-course criminology scholarship has incorporated identity as a core concept explaining desistance or disengagement from crime over time. Individuals who transform their identities from anti to prosocial or who are ready to move away from their past selves are more likely to desist from crime. However, the role of identity, particularly the forms of identity that have been theorized to influence desistance, has been understudied with respect to prison behavior. Understanding the ways in which identity relates to prison misconduct may help inform prison programming as well as theoretical perspectives drawing on the concept. The purpose of this study is to explore how various forms of identity are related to future prison misconduct, controlling for past misconduct and a host of other theoretical variables, in Minnesota prisons. The results indicate that two forms of identity, replacement self and cognitive transformation, are related to general misconduct but not violent misconduct in survival models. For general misconduct, both forms of identity are associated with a reduction in the risk of new convictions. Implications for theory and practice are discussed.

While specific responsivity factors are believed to either inhibit or facilitate successful involvement in programming, relatively little attention has been given to the validation of responsivity assessments used for correctional populations. Based on a sample of nearly 2,100 individuals confined in Minnesota prisons, this study examines the relationship between a needs and responsivity assessment system and multiple measures of program participation, dosage and completion. The responsivity domains—childhood trauma, mental health, religiosity, motivation and learning style—were significantly associated with at least one measure of programming. All but two of the needs domains also had a significant association with programming involvement. We discuss the implications of the findings for correctional research and practice.

This report estimates the cost of pure cybercrime to individuals in Australia in 2019. A survey was administered to a sample of 11,840 adults drawn from two online panels—one using probability sampling and the other non-probability sampling—with the resulting data weighted to better reflect the distribution of the wider Australian population.

Thirty-four percent of respondents had experienced some form of pure cybercrime, with 14 percent being victimised in the last 12 months. This is equivalent to nearly 6.7 million Australian adults having ever been the victim of pure cybercrime, and 2.8 million Australians being victimised in the past year.

Drawing on these population estimates, the total economic impact of pure cybercrime in 2019 was approximately $3.5b. This encompasses $1.9b in money directly lost by victims, $597m spent dealing with the consequences of victimisation, and $1.4b spent on prevention costs. Victims recovered $389m.

Objectives: Crime pattern theory and the related empirical research have remained rather a-temporal, as if the timing of routine activities and crime plays no role. Building on previous geography of crime research, we extend crime pattern theory and propose that an offender’s spatial knowledge acquired during daily routine activities is not equally applicable to all times of day. Methods: We put this extended theory to a first empirical test by applying a discrete spatial choice model to detailed information from the Netherlands on 71 offences committed by 30 offenders collected through a unique online survey instrument. The offenders reported on their most important activity nodes and offence locations over the past year, as well as the specific times they regularly visited these locations. Results: The results show that almost 40% of the offences are committed within the neighbourhoods of offenders’ activity nodes, increasing to 85% when including first-, second- and third-order neighbourhoods. Though not statistically significant in our small sample, the results further suggest that offenders are more likely to commit crime in neighbourhoods they have regularly visited at the same time of day than in neighbourhoods they have regularly visited at different times of day. Conclusion: Our extension of crime pattern theory is only tentatively supported. We argue for replication research with larger samples before any firm conclusions are warranted.

Data Justice and the Right to the City engages with theories of social justice and data-driven urbanism. It explores the intersecting concerns of data justice - both the harms and civic possibilities of the datafied society – and the right to the city - a call to redress the uneven distribution of resources and rights in urban contexts. These concerns are addressed through a variety of topics: digital social services, as cities use data and algorithms to administer to citizens; education, as data-driven practices transform learning and higher education; labour, as platforms create new precarities and risks for workers; and activists who seek to make creative and political interventions into these developments. This edited collection proposes frameworks for understanding the effects of data-driven technologies at the municipal scale and offers strategies for intervention by both scholars and citizens.

There is mounting concern over the potential harms associated with ultra-processed foods, including poor mental health and antisocial behavior. Cutting-edge research provides an enhanced understanding of biophysiological mechanisms, including microbiome pathways, and invites a historical reexamination of earlier work that investigated the relationship between nutrition and criminal behavior. Here, in this perspective article, we explore how this emergent research casts new light and greater significance on previous key observations. Despite expanding interest in the field dubbed ‘nutritional psychiatry’, there has been relatively little attention paid to its relevancy within criminology and the criminal justice system. Since public health practitioners, allied mental health professionals, and policymakers play key roles throughout criminal justice systems, a holistic perspective on both historical and emergent research is critical. While there are many questions to be resolved, the available evidence suggests that nutrition might be an underappreciated factor in prevention and treatment along the criminal justice spectrum. The intersection of nutrition and biopsychosocial health requires transdisciplinary discussions of power structures, industry influence, and marketing issues associated with widespread food and social inequalities. Some of these discussions are already occurring under the banner of ‘food crime’. Given the vast societal implications, it is our contention that the subject of nutrition in the multidisciplinary field of criminology—referred to here as nutritional criminology—deserves increased scrutiny. Through combining historical findings and cutting-edge research, we aim to increase awareness of this topic among the broad readership of the journal, with the hopes of generating new hypotheses and collaborations.

Research continues to explore factors that contribute to high rates of attrition among sexual assault cases. Comparatively little is known, however, about prosecutorial, as opposed to police, decision-making in these cases. Using a mixed-method approach to analyze (1) 175 case files from a midsize policing agency in the West with trained sexual assault investigators and (2) detailed prosecutor notes from 52 corresponding cases, we explore patterns in three key outcomes: (a) arrest, (b) referral for prosecution, and (c) charging. Logistic regression results indicate that fewer variables predicted case outcomes compared with previous studies, suggesting that specially trained officers may be more adept at dismissing “rape myth” factors. Qualitative analysis of prosecutorial case notes, however, revealed that prosecutors tended to compare specific case elements to an envisioned “ideal” case, which frequently aligned with some pervasive rape myths prevalent in society. Prosecutors focused heavily on convictability, anticipating how a potential jury would respond to the case. Although specially trained investigators may better disregard extralegal rape-myth factors, these myths still plague decision-making at the prosecutorial stage indirectly via concerns for juror interpretation of the facts. We find strong support for the “downstream” perspective of prosecutorial decision-making.

Why this guide? A wide variety of forms of misogyny and genderbased bigotry have spiked in recent years.1 This includes a documented rise in forms of male supremacist violence that are now recognized as part of the spectrum of domestic violent extremism, including threats, plots and attacks from misogynist incels. 2 3 Everyday forms of misogyny and hostile sexism, especially online, have also increased, with one study showing that misogynistic tweets positively predict domestic and family violence in the United States.4 Further, anti-feminist sentiments have been rising among Generation Z boys and young men.5 This rise in gender-based bigotry includes a surge of anti-LGBTQ+ ideas and beliefs, evidenced through the hundreds of discriminatory bills introduced across the United States in 2024.6 At the intersection of anti-Black racism, anti-LGBTQ+ hate and misogyny, Black women, girls and transgender women experience an outsized amount of harm and violence. On the community level, these harms manifest from harassment at Pride month events and attacks on LGBTQ+ friendly businesses to unequal reproductive health care access and deadly transmisogynist violence. These surges are partially explained by the sheer breadth of online spaces where gender-based hate is fostered and thrives, such as video game chats, comment trolls on mainstream social media sites, and dedicated Reddit pages focused on ways to manipulate and denigrate women. Because hateful comments, memes and short-form videos are often infused with irony, satire or other forms of humor, gender-based hate online is sometimes disguised as “just a joke” or hidden behind the excuse of having two different meanings. Hate and policing individuals’ gender have also been legitimized and normalized by politicians, elected officials, and online influencers who peddle supposed success stories of wealth and status that rely on the exploitation and domination of women. And extremist groups who embrace racism and political violence, like the Proud Boys, have joined the fray by directly targeting bookstores that host Drag Story Hours and demonstrations advocating for abortion rights. Falsely linking drag performances and LGBTQ+ people with sexual predation, sometimes called “grooming,” they have sought new ways to build sympathy among mainstream conservatives.7 Collaboration & Scope A collaborative team of experts from the Southern Poverty Law Center (SPLC) and the Polarization & Extremism Research & Innovation Lab (PERIL) drafted this guide. It is part of a broader public health approach for the prevention of violence and harm stemming from extremism, manipulative disinformation and dehumanizing rhetoric. Our organizations root our development of this approach in communities’ needs and by centering support for targeted individuals and survivors. And our approach is necessarily noncarceral, so that we can emphasize education and prevention over monitoring, surveillance and other security-based approaches. This guide is a resource for caregivers who surround and support young people – parents and relatives, teachers and educators, counselors and therapists, coaches and youth mentors, and more. It includes an overview and introduction to the concepts, trends and risks related to gender-based bigotry alongside the tools to build resilience and awareness, as well as ways to intervene. It also provides strategies and resources to support survivors and targeted individuals and communities. While this guide cannot cover every harm that young people will encounter related to gender-based bigotry, we aim for as wide a breadth as possible.

The metaverse is an emerging convergence of technologies (e.g., virtual reality and blockchains) that enables users to experience mixed/extended realities for various legitimate purposes (e.g., gaming, tourism, manufacturing and education). Unfortunately, the crime and security implications of emerging technologies are often overlooked. To anticipate crimes that the metaverse might facilitate, we report the findings of a nominal group technique (NGT) study, which involved a state-of-the-art scoping review of the existing literature and elicitation exercises with two groups of experts (one a diverse group from the UK and Europe, the other representing international law enforcement) with a wide range of expertise. A total of 30 crime threats were identified in the literature or by participants. The elicitation exercises also explored how harmful, frequent, achievable and defeatable participants anticipated that the crimes identified would be. Ratings for these aspects were largely consistent across the two samples, with crimes of a sexual nature (e.g., child sexual abuse material), and crimes against the person (e.g., hate crime) being rated as presenting the highest future risks (i.e. being high harm and high frequency) and being the most difficult to address. The findings illuminate understanding of the most (and least) harmful and likely crime threats the metaverse could facilitate and consequently help stakeholders to prioritise which offences to focus on. In discussing how the crime threats might be addressed, we consider roles and responsibilities and how theory about the management of physical places might inform crime prevention in the metaverse(s).

The presence of law enforcement in schools has been a controversial issue for decades. Dual concerns about rising rates of violence among youth coupled with increased attention paid to school shootings were a catalyst for federal funding for more police, frequently referred to as “School Resource Officers” (SROs), in schools. In fact, rates of youth violence were plummeting independent of law enforcement interventions and the impact of SROs on school shootings has been dubious at best. Additionally, SROs have been linked with exacerbating racial disparities in justice involvement and youth being driven deeper into the juvenile and adult criminal justice systems. Rather than preventing crime, SROs have been linked with increased arrests for non-criminal, youthful behavior, commonly known as the school-to-prison pipeline.
