This project involved qualitative primary research into criminality within seaports, by observing how ports, as microcosmic realities run through formal and informal relationships and have specific security vulnerabilities, which facilitate different types of illegal or deviant behaviours. Research has been carried out in two European ports (Liverpool and Genoa) and three non-European ones (Montreal, New York and Melbourne), which are either targets of, or transit zones for, criminal activities and criminal networks.  The main aim of this comparative research project was to improve policy understanding of how the complex relationships within ports act as conduits or facilitators in how criminal networks operate in the territory of and around the ports. With specific attention to the changing geopolitical conditions surrounding the port of Liverpool within the Brexit scenario, the study has looked at what could be learned in the British experience from international ones both in terms of security and in terms of transnational risk assessments.

Crime and policing activities routinely involve interactions between strangers and require the interacting parties to make highly consequential decisions under time pressure. Under such conditions, stereotypes based on visual or other cues can influence behavior. This review considers the role of stereotypes in shaping the manner in which such interactions proceed and the likelihood with which they occur in the first place. Our focus is primarily on robbery, murder, police stops and searches, and the use of deadly force, but the arguments apply more generally. We also consider how stereotypes can become entrenched through the behavioral changes they induce, given large differences across offenses in rate of arrest and prison admission.

In 1962, the FBI reported a national homicide clearance rate of 93%. That rate dropped 29 points by 1994. This Great Decline has been studied and accepted as a real phenomenon but remains mysterious, as does the period of relative stability that followed. The decline was shared across regions and all city sizes but differed greatly among categories defined by victim race and weapon type. Gun homicides with Black victims accounted for most of the decline. We review the evidence on several possible explanations for the national decline, including those pertaining to case mix, investigation resources, and citizen cooperation. Our preferred explanation includes an upward trend in the standard for arrest, with strong evidence that although clearance-by-arrest rates declined, the likelihood of conviction and prison sentence actually increased. That result has obvious implications for the history of policing practice and for the validity of the usual clearance rate as a police performance measure.

It is generally believed that the use of alcohol and cocaine alone and especially in combination elicits aggression and violent behaviour. Though there is overwhelming proof that heavy alcohol use is associated with violence, this is not the case for cocaine. Still, in the popular press and by spokesmen of the police, cocaine use is seen as a cause of violent incidents. In the current systematic review, available data from human studies on the relation between cocaine and violent behaviour is presented. In particular, we present scientific data on the acute induction of violence by cocaine alone, as well as, that by the combination of cocaine and alcohol known to be frequently used simultaneously.

Results: show that there is only weak scientific evidence for the acute induction of violent behaviour by cocaine, either when used alone or in combination with alcohol. Based on these data we were also able to refute misconceptions about the relation between cocaine and violence published in the popular press and governmental reports, because it appeared that there was hardly any empirical support for this widely shared opinion. Probably, contextual factors, including cocaine use disorder and personality disorder, may better explain the assumed association between cocaine and violence.

Much research has shown that the first lockdowns imposed in response to the COVID-19 pandemic were associated with changes in routine activities and, therefore, changes in crime. While several types of violent and property crime decreased immediately after the first lockdown, online crime rates increased. Nevertheless, little research has explored the relationship between multiple lockdowns and crime in the mid-term. Furthermore, few studies have analysed potentially contrasting trends in offline and online crimes using the same dataset. To fill these gaps in research, the present article employs interrupted time-series analysis to examine the effects on offline and online crime of the three lockdown orders implemented in Northern Ireland. We analyse crime data recorded by the police between April 2015 and May 2021. Results show that many types of traditional offline crime decreased after the lockdowns but that they subsequently bounced back to pre-pandemic levels. In contrast, results appear to indicate that cyber-enabled fraud and cyber-dependent crime rose alongside lockdown-induced changes in online habits and remained higher than before COVID-19. It is likely that the pandemic accelerated the long-term upward trend in online crime. We also find that lockdowns with stay-at-home orders had a clearer impact on crime than those without. Our results contribute to understanding how responses to pandemics can influence crime trends in the mid-term as well as helping identify the potential long-term effects of the pandemic on crime, which can strengthen the evidence base for policy and practice.

How does crime develop over the life course? And how do age, life circumstances, and prior offending affect this development? This thesis seeks to answer these two questions that are central to present day developmental and life course criminology. The research presented is based on the Criminal Career and Life course Study (CCLS), a longitudinal study covering the criminal careers of over 5,000 offenders from early adolescence to late adulthood. Employing a range of statistical techniques especially designed for analyzing longitudinal data, this research gives insight in issues such as the reality of life course persistent offenders, the influence of marriage and parenthood on offending, and the role of prior offending in generating stability and change in offending over time.
