This study explored, among persons undergoing drug treatment, whether one’s likelihood of possessing any felony charge differed depending upon their primary drug of choice. The results showed that individuals in drug treatment who reported cocaine or heroin/opioids as their primary drug of choice had significantly higher probabilities of having a felony charge than those who reported alcohol as their primary drug of choice.

Last October, progressive Jews were shocked by the raw antisemitism displayed by their erstwhile allies on the political left. After Hamas terrorists tortured, raped, or murdered more than 1200 Israeli civilians and took some 200 civilians hostage, some progressives – especially on college campuses – celebrated. They chanted the Palestinian mantra “from the river to the sea,” seeking to erase Israel (and Jews) from the face of the earth. The number of antisemitic incidents on campus soared, coming from both students and faculty. A Stanford lecturer forced Jewish students to the back of the classroom and labeled them “colonizers.” Jewish students had to barricade themselves inside a library at Cooper Union, and Jewish students at MIT were told by faculty to avoid the university’s main lobby for their own safety. Many university presidents who had previously sent out campus-wide emails condemning the murder of George Floyd, the Russian invasion of Ukraine, the overruling of Roe v. Wade, and countless other world events suddenly discovered the Kalven Principles and claimed it would be inappropriate for them to take sides, or issued weak statements about how the situation in the Middle East was complicated. This double standard continued as some universities responded to student calls for genocide of Jews by invoking principles of free speech, principles that had been notably ignored when the speech in question was directed at other groups. Most campus DEI (diversity, equity, and inclusion) offices, especially at the most elite universities, had nothing to say about the surging antisemitism. This essay explains why no one should have been shocked, or even mildly surprised, by the progressive response to the massacre. Progressive or “woke” culture –as exemplified by critical race theory, anti-racism of the Ibram X. Kendi variety, and, especially on college campuses, the DEI juggernaut – is necessarily and inevitably antisemitic at its core. That these related movements have now exposed their antisemitism publicly is no surprise: antisemitism is bred in their bones.

Combating violent crime ranks among the Department of Justice’s top priorities to improve community safety. Numerous law enforcement and criminal justice strategies target violent crime and gang violence, including both place- and person-based approaches. However, few of these strategies have been evaluated using the most rigorous of research designs, the randomized controlled trial (RCT). The current study helps to fill this gap by using an RCT to evaluate a focused deterrence program operated by the St. Louis, Missouri, Metropolitan Police Department (SLMPD) and the Missouri Department of Corrections (MODOC): the St. Louis Police Partnership. In fall 2016, the SLMPD and the St. Louis offices of MODOC’s Division of Probation and Parole entered into a partnership to monitor and facilitate service delivery to persons under probation or parole supervision at high risk for gun-related crimes (hereafter the Police Partnership). The Police Partnership is centered on face-to-face meetings in which a police officer and community corrections officer meet with a probationer or parolee who has committed a firearm-related offense. The meetings typically last between 15 and 30 minutes, and most meetings are held in the participant’s home, with the remainder held in a probation and parole office, at the participant’s place of employment, or via phone or video (the meetings are referred to hereafter as “home visits”). This evaluation focuses on meetings held since June 2020, when the National Institute of Justice began funding an evaluation of the program’s effectiveness in reducing criminal activity and increasing prosocial outcomes such as education, training, employment, and drug treatment. A total of six police officers, including replacements, have been involved with the program since its beginning. The Police Partnership continues to date. St. Louis is a strategically important site for this evaluation because it faces a critical problem of criminal violence, particularly firearm-related violence. In 2016, the year the Police Partnership began, the St. Louis homicide rate of nearly 60 per 100,000 city residents was the highest among the nation’s cities (Mirabile and Nass, 2018) and approximately five times greater than the average rate for cities of comparable size. In 2016, 92 percent of St. Louis homicides were committed with a firearm (Metropolitan Police Department, City of St. Louis, 2016). St. Louis’s rate of total violent crime (homicide, aggravated assault, rape, and robbery) was more than two-and-a-half times the rate in cities of similar size. The St. Louis violent crime rate of 1,913.2 crimes per 100,000 residents exceeded the rate in other cities confronting serious violent crime problems, including Baltimore (1,780.4), New Orleans (1,069.7), and Chicago (1,105.5). In 2016, 59 percent of aggravated assaults, the largest category of violent crime in St. Louis, were committed with a firearm (Metropolitan Police Department, City of St. Louis, 2017) . Firearm violence persists as a major public problem in St. Louis.

This report details the key trends and developments in human smuggling in Libya in 2023. In large degree, the year was one of continuity with the patterns seen in 2022. Over the course of the year, for example, 77 470 migrants departed the Libyan coast, only marginally higher than 2022’s figure of 75 500.1 Furthermore, hybrid migration, in which migrants travel to Libya regularly or semi-regularly before attempting the sea crossing to Europe, accounted for an estimated 75% of these departures, also roughly similar to the proportion recorded in 2022. Many of the migrants involved in hybrid journeys first arrived in Libya at Benina airport in the east of the country. This indicates the increasing importance of eastern Libya to human smuggling writ large. In addition to the migrant arrivals at Benina airport, eastern Libya also saw a dramatic rise in departures from the coastal areas in and around Tobruk in 2023, with some 40% of sea crossings in the first half of the year taking place from there. Some, though not all, of the migrants leaving from the east coast had arrived in Benina. While heightened enforcement by the Libyan Arab Armed Forces (LAAF) suppressed departures from the Tobruk hub in the second half of 2023, the body reportedly continued to allow Benina to be used as the main air travel arrival point for hybrid migration for the rest of the year. Thus, the LAAF clearly emerged as one of the main actors influencing hybrid migration in Libya in 2023. Following the shutdown of the Tobruk system, hybrid migration sea crossings were displaced to the west coast. By August, departures from this area had increased significantly and there were reports of migrants accumulating in warehouses in several hubs. In October, a notably large series of departures from Zuwara occurred at a remarkable rate. Increased departures from the west coast indicate that entrenched smuggling networks remain ready to seize opportunities. Given the political and security fragmentation of the region, these networks are likely to underpin the resilience of human smuggling in Libya for the foreseeable future. A notable element that remained marginal in 2023 was trans-Saharan smuggling through Libya. This was once a major route for migrants departing from Libya, but has declined significantly since 2017/18 due to insecurity and migrant abuse in Libya and law enforcement action in downstream countries. One of the few significant developments was the relatively moderate but growing number of Sudanese refugees fleeing the civil war in that country. However, this was not substantial enough to drive systematic changes in the dynamics of overland human smuggling. Similarly, Sudanese nationals did not leave the Libyan coast in large numbers. This is the latest GI-TOC monitoring report on human smuggling in Libya. It builds on the series of annual reports that has been issued since 2017, tracking the evolution of human smuggling in Libya, as well as the political, security and economic dynamics that influence it.2

Today, communities across Louisiana and Southeastern coasts are emerging from the shadow of Hurricane Ida. The storm has left New Orleans without power, surrounding areas flooded, and thousands evacuated from their homes.

Since Hurricane Katrina swept through Louisiana almost exactly 16 years ago, the National Academies have helped produce scientific insights and recommendations through initiatives such as the Resilient America Program to help policymakers avoid the worst impacts of future disasters — addressing questions like: How can we improve hurricane prediction? How can cities and states better manage evacuations? How can we make sure the electrical grid is ready for increasingly intense storms?

This handbook companion document supports Public Information and Warnings (AIDR 2021) and provides guidance on the elements of the Australian Warning System.

The role of warnings in a public information and warning context is to provide point-in-time information about a hazard that is impacting or is expected to impact communities. It describes the impact and expected consequences for communities and includes advice on what people should do.

Previously, there have been different warning systems for different hazard types across Australia. The Australian Warning System was adopted by ANZEMC in March 2021 and aims to provide a consistent warnings approach to Australian communities.

The system is a three-level scaled warning system and includes a nationally consistent set of hazard icons for each warning level to show warnings on various publishing platforms (e.g. websites and apps) and provides calls to action. There are icons for cyclone, bushfire, flood, extreme heat, storm, and other. There is a consistent shape and colour scheme, with icons increasing in size as the warning level increases.

Each warning level is to be combined with an action statement to give the community clearer advice about what to do. Calls to action can be used flexibly across all three warning levels and contextualised for each hazard within each state or territory.

The system builds on existing warning frameworks and applies to bushfire, flood, severe storm, cyclone and extreme heat – but is designed to be adaptable and scalable to other hazards.

The 2018 Tropical Cyclone Hazard Assessment (TCHA18) provides an evaluation of the likelihood and intensity (“how big and how often”) of the occurrence of tropical cyclone winds across the Australian region, covering mainland Australia, islands and adjacent waters. It is a probabilistic evaluation of the expected maximum gust wind speeds with a range of annual exceedance probabilities (or conversely, average recurrence intervals). The assessment is derived using a statistical-parametric model developed by Geoscience Australia called the Tropical Cyclone Risk Model (TCRM). Maximum 0.2-second duration, 10-metre above ground wind speeds are calculated for Standard Australia's AS/NZS 1170.2 (2011) terrain category 2 (0.02 m roughness length) surface conditions, over a 0.02 degree grid across Australia. Maps of average recurrence interval (ARI) wind speeds of 100- and 500-year ARI are provided in a separate product suite.

Ask a Queenslander where tropical cyclones occur and the inevitable response will be, North Queensland. While most of the tropical cyclones have made landfall north of Bundaberg, the cascading and concurrent effects are felt much further afield. The major flooding following Tropical Cyclone Yasi in 2011 and Tropical Cyclone Debbie in 2017 are 2 examples where impacts were felt across the state, and the damage to the banana plantation following Tropical Cyclone Larry (2006) was felt nationally. Acknowledging that climate is influencing the intensity and frequency of intense severe weather hazards, understanding how tropical cyclone hazard varies under future climate conditions is critical to risk-based planning in Queensland. With this climate influence, along with increasing population and more vulnerable building design in South East Queensland (relative to northern Queensland), there is an urgent need to assess the wind risk and set in place plans to reduce the effects of a potential tropical cyclone in South East Queensland.

Following a series of natural disasters, including Hurricane Katrina, that revealed shortcomings in the nation's ability to effectively alert populations at risk, Congress passed the Warning, Alert, and Response Network (WARN) Act in 2006. Today, new technologies such as smart phones and social media platforms offer new ways to communicate with the public, and the information ecosystem is much broader, including additional official channels, such as government social media accounts, opt-in short message service (SMS)-based alerting systems, and reverse 911 systems; less official channels, such as main stream media outlets and weather applications on connected devices; and unofficial channels, such as first person reports via social media. Traditional media have also taken advantage of these new tools, including their own mobile applications to extend their reach of beyond broadcast radio, television, and cable. Furthermore, private companies have begun to take advantage of the large amounts of data about users they possess to detect events and provide alerts and warnings and other hazard-related information to their users.

More than 60 years of research on the public response to alerts and warnings has yielded many insights about how people respond to information that they are at risk and the circumstances under which they are most likely to take appropriate protective action. Some, but not all, of these results have been used to inform the design and operation of alert and warning systems, and new insights continue to emerge. Emergency Alert and Warning Systems reviews the results of past research, considers new possibilities for realizing more effective alert and warning systems, explores how a more effective national alert and warning system might be created and some of the gaps in our present knowledge, and sets forth a research agenda to advance the nation's alert and warning capabilities.

As a strategy for manipulating the consequences of disasters, evacuation - that is, the relocation of people from a place of high threat to a relatively safer place - has a particularly long history and constitutes a common societal adjustment to environmental hazards. The Greek historian Herodotus described the Egyptians systematic evacuations to escape the seasonal flooding of the Nile River as early as the fourth century B.C. During the Middle Ages in Europe, significant movements of populations occurred as a function of people’s attempts to escape various epidemics. The history of warfare, from the Dorian invasion of central Greece in 1130 B.C., through the Vietnam conflict of the 1970s and the recent invasion of Afghanistan, is also a history of population movements, many of which began as evacuations. Thus, evacuation has been used by many societies for centuries as an adjustment to cope with disasters.

Particularly with regard to riverine flooding, pre-impact evacuation of the threatened population is an important management strategy which may be used by authorities. Of course, evacuation is not the only, or even the “best”, means of coping with flood hazards. Other options include controlled building in flood plains and enhanced building design and construction techniques. Such measures, however, are easily incorporated into new construction and communities, but not so easy to institute in established comnites where such protections tend to be developed slowly in connection with continuous building and renovation. Thus, many communities must depend, in part or completely, upon measures other than elaborate land use planning or restrictive construction codes in their plans to adjust to floods.

“Operations research” and “sociology” are infrequently discussed together. Though an analytic approach is positioned to benefit society through quantitative measurement and evaluation. This research reviews literature surrounding the sex trafficking victimization experience during a lifetime: namely sex trafficking, lifetime experiences, and Markov modelling. With the results of the literature review, a framework is defined to evaluate and assess the experience of sex trafficking victimization during a lifetime for individuals and/or populations. Particularly valuable outcomes of this research are the extensive review of related literature and the definition of a fully interconnected framework of the experiences individuals face within sex trafficking victimization. The defined framework is presented to support current analytic interests of anti-trafficking and policy-maker groups, as well as provide the foundation for further developments to better support impacted communities and society.

Although it is particularly pronounced in Oregon, there is no question that the fentanyl epidemic is imposing severe economic costs across the nation. The current report quantifies some of these costs and describes the state policy environment. Public policy regarding drug use is evolving rapidly in Oregon as we speak. As with all CSI does, the primary goal of this report is to educate and inform Oregonians on policy issues such as this that impact their lives. Key Findings • The economic cost of Oregon’s fentanyl crisis is more than $31 billion annually, up from $5.88 billion in 2017. • Enough fentanyl was seized last year to kill every Oregonian more than 20 times over. • Most western states have seen above-average growth in fentanyl use during recent years. Even so, Oregon’s experience stands out relative to its neighbors. Since the pandemic began, fentanyl-related overdose deaths in Oregon have increased by over 1,000%, more than in any other state. Alaska’s experience is the only one that even comes close. • Although Oregon’s decriminalization experiment cannot be blamed for all the disproportionate local impact of the fentanyl epidemic, it is clearly playing a role. When decriminalization went into effect in February 2021, Oregon ranked 38th out of 48 states with available data in the rate of fentanyl related overdose deaths. By January 2024, Oregon’s rank rose to 13th. • Many voters and policymakers quickly experienced regrets associated with the decriminalization effort and are making some efforts to improve the law. During the 2023 legislative session, legislators enacted House Bill 4002, which created a new misdemeanor for simple drug possession. The new law gives leeway to counties on how to implement it locally, and we are likely to learn much as the different programs evolve.

Introduction: Forensic nurses routinely provide services to sexual assault victims who are uncertain about reporting their assault to police. The purpose of this study was to determine whether assault characteristics are related to the concerns about police reporting expressed by sexual assault victims who have forensic evidence collected but do not report their assault to police at that time. Methods:We Analyzed Medical records of patients who received services at a hospital-based forensic nursing program between 2010 and 2021. Records were included if a sexual assault evidence kit was collected, the patient declined to report the assault to police, and the patient completed a nonreport sexual assault evidence kit supple ment form that included a question asking why they chose not to report the assault (N = 296). We qualitatively analyzed patients' reasons for not reporting the assault and then used two-variable case-ordered matrices and chi-square analyses to explore relationships between reasons for not reporting and assault characteristics. Results: Identified reasons for not reporting included lacking information about the assault, fear of harm/retaliation, andself-blame/minimization. Physicalforce,drug/alcohol consumption,andvictim–offender relationships were related to patients referencing lacking information and fearing harm/retaliation as reasons for not reporting, but not related to the frequency of patients referencing self-blame/minimization. Implications: Results indicate that assault characteristics are related to reasons for not reporting at the time of the medical forensic examination. Being aware of these

There have been numerous debates regarding the educational practice of grade retention and social promotion. This study analyzes the effect of an exogenous policy reform in China that abolishes grade retention during the compulsory education period. We exploit the staggered introduction of the reform across provinces and estimate a flexible difference-in-differences model that can capture the effect of exposure to the reform in different grades. The results indicate that abolishing grade retention significantly decreases the probability of junior high school completion, and most of these negative impacts are concentrated among students exposed to the reform in early grades. Moreover, rural children and boys are more likely to be negatively affected by the reform. Finally, we find that the reform increases the likelihood of later criminal behavior in early adulthood.

Crime has undeniably and dramatically increased over the last decade in Colorado. The pandemic-related policy restrictions and resulting economic disruptions brought further stress to society, which exacerbated problems related to crime. The result has been billions of dollars in additional costs borne by Coloradans. These costs are felt in many ways, both directly by the victims, and indirectly by the community. It is important to distill the jaw-dropping impact of crime down to numbers that everyone can grasp. The numbers show trends and enable conclusions, which in turn can be tested. Numbers remove the emotional impact and personal tragedy of crime and lead to dispassionate, practical solutions to what is, in part, an economic issue. All victims know that crime is intensely personal. Most people never fully recover from the impact of being victimized. Behind every statistic of violent crime, theft of valued possessions or any violation of one’s right to live a safe and secure life, is a person and that person’s family and friends – are each damaged by a criminal act. The primary and consistent policy trend in Colorado has been to discourage the jailing of those arrested for committing crimes and to reduce the severity of punishment for those convicted. However well intended, these recent policies must be monitored to ensure the costs from the unintended – albeit predictable consequences do not outweigh the anticipated benefits. Given the concerning trends and high costs, it is imperative that policy makers implement timely, transparent, and actionable accountability metrics, that allow them to diagnose specific system level problems and individual policy decisions across the multiple dimensions of criminal justice in Colorado. Let us move forward with the important work of understanding the impact of public policy on the lives of our community. While we’re interpreting data and delving deeper into cause-and-effect, we must also remember the thousands and thousands of victims who have suffered and deserve justice. Colorado’s crime surge increased over the last two years but started long before the pandemic - - - From 2010 through 2019, Colorado’s population-adjusted annual murder rate increased by an annual average of 8%, motor vehicle theft by 6%, and assault by 3%. Average monthly crime in 2021 per 100,000 Coloradans is 28% higher than in 2011, and 11% higher than in 2020 The monthly murder rate increased 20% in both 2019 and 2020. The 2021 total rate of crime is 14% higher than it was in 2019. This trend exceeds the 12% increase Colorado experienced between 2009 and 2012. etc........

Research Question -  Which method for deriving a Crime Harm Index (Policing 10:171 183, 2016) for Sweden from criminal justice sources offers the best evidence for providing a sensitive indicator of differences in harm levels across offence categories? Data The number of days of imprisonment for each offence category associated with five different kinds of scales were extracted and compared: consensus by an expert panel of judges, the statutory maximum penalties, statutory minimum penalties, the average of maximum and minimum penalties and the average of actual sentences imposed in a recent time period for each crime type. Unlike the UK, for which the Cambridge Crime Harm Index draws on sentencing guidelines, Sweden has no such guidelines to offer. Methods - The data were compared for sensitivity defined as the difference in length of imprisonment days between high and low severity crimes, as well as other characteristics of the data sources. Findings - Given the available alternatives, the sentencing data average of actual sentences handed down by crime type provided the greatest reliability and sensitivity across the penalties for offences of high and low severity. Applying that method to both crime trends and crime mapping produces substantially different results from counting all crimes with equal weight and can be used by police and others to allocate resources with greater precision in relation to harm prevention. Conclusions - On both empirical and normative grounds, the average sentences in a recent time period for each crime category provides the most sensitive and democratic method for establishing an officially recognized Swedish Crime Harm Index.

In order to launder large amounts of money, (drug) criminals can seek help from financial facilitators. According to the FATF, these facilitators are operating increasingly business like and even participate in professional money laundering networks. This study examines the extent to which financial facilitators in the Netherlands exhibit business-like charac teristics and the extent to which they organize themselves in money laundering networks. We further examine the relationship between business-like behavior and individual money launderers’ position in the social network. Using police intelligence data, we were able to analyze the contacts of 198 financial facilitators who were active in the Netherlands in the period 2016–2020, all having worked for drug criminals. Based on social network analysis, this research shows that financial facilitators in the Netherlands can be linked in extensive money laundering networks. Based on the facilitators’ area of expertise, roughly two main types of professional money laundering networks can be discerned. Some subnetworks operate in the real estate sector, while others primarily engage in underground banking. Furthermore, the application of regression models to predict business-like behavior using individual network measures shows that facilitators with more central positions in the net work and those who collaborate with financial facilitators from varying expertise groups tend to behave more business-like than other financial facilitators

Aim

There is a growing literature analyzing money laundering and the policies to fight it, but the overall effectiveness of anti-money laundering policies is still unclear. This paper investigates whether anti-money laundering policies affect the behavior of money launderers and their networks.

Method

With an algorithm to match clusters over time, we build a unique dataset of multi-mode, undirected, binary, dynamic networks of natural and legal persons. The data includes ownership and employment relations and associated financial ties and is enriched with criminal records and police-related activities. The networks of money launderers, other criminals, and non-criminal individuals are analyzed and compared with temporal social network analysis techniques and panel data regressions on centrality measures, transitivity and assortativity indicators, and levels of constraint.

Findings

We find that after the announcement of the fourth EU anti-money laundering directive in 2015, money laundering networks show a significant increase in the use of foreigners and corporate structures. At the individual level, money launderers become more dominant in criminal clusters (increased closeness centrality). This paper shows that (the announcement of) anti-money laundering policies can affect criminal networks and how such effects can be tested.

 It is important to understand the amounts and types of money laundering flows, since they have very different effects and, therefore, need different enforcement strategies. Countries that mainly deal with criminals laundering their proceeds locally, need other measures than countries that mainly deal with foreign illegal investments or dirty money just flowing through the country. This paper has two main contributions. First, we unveil the country preferences of money launderers empirically in a systematic way. Former money laundering estimates used assumptions on which country characteristics money launderers are looking for when deciding where to send their ill‑gotten gains. Thanks to a unique dataset of transactions suspicious of money laundering, provided by the Dutch Institute infobox Criminal and Unexplained Wealth (iCOV), we can empirically test these assumptions with an econometric gravity model estimation. We use this information for our second contribution: iteratively simulating all money laundering flows around the world. This allows us, for the first time, to provide estimates that distinguish between three different policy challenges: the laundering of domestic crime proceeds, international investment of dirty money and money just flowing through a country

Objectives: This paper examines the impact of local economic activity on criminal behavior. We build on existing research by relaxing the identification assumptions required for causal inference, and estimate the impact of local economic activity on recidivism.

Methods: We use the fracking boom as a source of credibly exogenous variation in the economic conditions into which incarcerated people are released. We replicate and extend existing instrumental variables analyses of fracking on how many released offenders return to state prison seperately from aggregate crime and arrests.

Results: Our instrumental variables estimates imply that a ten thousand dollar increase in the value of per capita production is associated with a 2.8% reduction in the 1-year recidivism of ex-offenders at the county level. Improved labor market conditions, specifically an increase in wages for young adults, may explain a non-negligible fraction of the reduction in recidivism associated with economic booms. In contrast, we replicate existing work finding that fracking increased aggregate measures of crime and arrests.

Conclusion: Increased economic opportunity appears to have a different impact of overall crime than on recidivism. This suggests that the relationship between economic opportunity and offending may be conditioned by local social ties. Further research examining how social connections and labor markets affect individual criminal behavior is needed.
