Jurors and other legal decision-makers are often required to make judgments about the likely memory accuracy of another person. Legal systems tend to presume that decision-makers are well-placed to make such judgments (at least in the majority of cases) as a result of their own experiences with memory. However, existing research highlights weaknesses in our abilities to assess the memories of others and suggests that these weaknesses are not easily ameliorated through the provision of information. In this work we examine the accuracy of layperson assessments of “real” eyewitness identifications following observation of a mock crime. We examine whether novel instructions, characteristics and beliefs of assessors, and underlying reasoning strategies are associated with improved or impaired judgment accuracy. The results support prior research in demonstrating a tendency towards over-belief in the accuracy of identifications. They suggest that reliance on what witnesses have said rather than attempts to make inferences from their statements (e.g., in relation to the level of detail provided or non-verbal cues in testimony) is associated with greater accuracy in assessments and that some individual differences and beliefs about memory are also associated with greater accuracy. However, there was no evidence that the instructions tested were effective. We discuss the implications of results for procedure surrounding the evaluation of memory in the legal context.

Background: Health and safety are critical pillars of functional higher education systems. In South African universities, recurring incidents have highlighted vulnerabilities, particularly concerning gender-based violence (GBV), student housing conditions, infrastructure safety, and campus crime. Methods: This study employed a document-based qualitative approach, analysing public records, police reports, campus press statements, and national media coverage of incidents reported at South African universities (2015 to 2024). The study is guided by public health and victimology frameworks to examine systemic risk factors and institutional responses. Results: The findings indicate increased reports of GBV, multiple student deaths related to substandard residence conditions, infrastructure-related fatalities, and a lack of consistent institutional safety policies. A pattern of poor infrastructure management, weak inter-institutional communication, and failure to implement recommendations following major incidents emerged across the dataset. Conclusions: South African universities remain exposed to preventable student risks. Targeted interventions, mandatory safety audits, emergency response units, and accountability structures are urgently needed to address systemic failings and protect student welfare. The study supports Sustainable Development Goals 3 and 4 by linking campus safety to student well-being and equitable access to higher education. Full article

The literature shows greenspaces generally increase nearby property values, but in Riyadh, this relationship is complex and understudied. Existing studies lack sector-specific analyses across Riyadh’s neighborhoods, overlook the impact of the Green Riyadh Project launched in 2019, and fail to address negative externalities associated with large greenspaces in an arid, privacy-conscious context. Such paradoxical impact of larger greenspaces bordering major roads at the neighborhood edge, unexpectedly reduce property values by 2–4% due to petty crime, congestion, poor upkeep, and privacy concerns, contrasting with 10–18% premiums for properties abutting greenspaces with restricted access in affluent neighborhoods. Global studies typically report positive greenspace effects, so negative impacts in specific Riyadh sectors are surprising. This highlights the city’s unique arid, cultural, and urban dynamics in addressing this research gap. The research uses purposive quota sampling of Riyadh neighborhood greenspaces and a mixed-methods approach of quantitative hedonic pricing analysis combined with qualitative semi-structured interviews with real estate agents. Findings underscore the need for tailored urban planning (e.g., mitigating petty crime, overcrowding, poor maintenance). This suggests the importance of integrating green infrastructure into urban planning, not only for its ecological and social benefits but also for its tangible positive impact on property values. Poor greenspace upkeep and safety concerns can reduce price premiums of abutting properties. Full article

Sexual assault crimes consist of acts committed without consent and represent a major global issue with serious implications for victims. These acts have both short- and long-term consequences on the physical, mental, and sexual health of victims, with sexually transmitted infections (STIs) being one of the direct outcomes of such crimes. Sexually transmitted infections constitute a serious global public health problem and can lead to severe consequences. These infections may be caused by bacteria, viruses, or parasites and are transmitted through sexual contact. Some of the most common STIs among the general population and victims of sexual crimes include gonorrhoea, chlamydia, trichomoniasis, and syphilis. In most carriers, these infections are asymptomatic, making their detection particularly challenging. Considering the importance of further research in this field, the primary objectives of this study are to review the existing literature on the incidence of major STIs in victims of sexual crimes, to identify the various risk factors associated with these infections, and to explore their public health implications. Additionally, this study aims to assess different STI detection techniques, analyzing their advantages and disadvantages. Studies on this topic are crucial for better understanding the role of sexually transmitted infections in the context of sexual crimes. However, throughout this work, it was verified that point-of-care methods are a good option to allow the diagnosis to be faster and more accurate, when compared to other methods of detecting sexually transmitted infections.

In a country where the majority of crimes remain unreported, uninvestigated, and unpunished, law enforcement faces considerable challenges in obtaining high-quality data that are consistent, reliable, and timely to effectively plan and deploy their strategies. By leveraging publicly available data, this paper identifies high-vulnerability areas for commercial burglary within the Metropolitan Area of Monterrey, utilizing a variable that incorporates the key dimensions of routine activity theory in criminology. This is accomplished by constructing an index through principal component analysis, followed by spatially grouping the resulting variable using the global indicator of spatial association (LISA). The results allow us to focus strategies to combat commercial burglary on 16.82% of the studied territory and establish an order of priorities to address the most vulnerable areas one by one. Also, the results allow us to implement prevention actions in broader zones by generating clusters around areas that share similar attributes. Full article

Millions of young Africans earn a variety of qualifications annually, yet the majority return without prospects for employment. This challenge has become a catalyst for inequality, poverty, crime involvement, and international migration. Empirical discourse points to education—such as a pedagogy that is chiefly theory-oriented rather than aligned with a knowledge economy, mismatched skills, and irrelevant qualifications—as constraints that contribute to the unemployment of the continent’s vibrant young graduates. Amidst this surging issue, the call for transformation in higher learning has never been clearer. Focusing on rural landscapes, this case study analysed the contextual employability potential of graduates pursuing an entrepreneurial university trajectory in Africa, illustrating why the paradigm should be implemented. The findings, based on qualitative data collected using a semi-structured questionnaire through one-on-one and remote approaches from stakeholders in universities across five African countries, highlight three dimensions central to this pathway. These include (1) curriculum alignment to advance cutting-edge qualifications and skill development that resonate with industrial demand and local economic priorities; (2) stakeholder embeddings in which universities strive to partner with local organisations and established alumni to provide mentorship, job leads, and referrals; and (3) innovation hubs that offer a variety of entrepreneurial support, real-world experience, and Indigenous entrepreneurship practices, leading to unique new ventures and employment opportunities. Implementing this strategy will enable rural-based universities in Africa to innovate in promoting graduate employability, socioeconomic advancements, and sustainable development, ultimately shaping a brighter future for the continent. Further studies could test the assumptions for broader application using statistical analysis. Full article

While the impact of trade openness on economic growth has been widely studied, its effect on township economies remains underexplored. In view of this empirical gap, this study examines the impact of trade openness proxied by export intensity on the technical efficiency of five major township economies in South Africa—Soweto, Khayelitsha, Alexandra, Tembisa, and Soshanguve—while considering the moderating role of information and communication technology (ICT). This aim speaks to the ongoing quest to unravel factors limiting the transformation of South African townships since the advent of democracy in 1994. The analysis uses an instrumental variable stochastic frontier model and annual panel data covering the 1995–2023 period. On average, the five townships were found to have operated 19% below their full potential during the sampling period, with Soweto being the least efficient. Holding constant factors peculiar to township economies, such as crime rates and informality, the main results show that ICT plays a positive moderating role in reducing trade-related technical inefficiencies of these townships. This finding underscores the importance of targeted policy interventions, such as investments in digital infrastructure and digital literacy programs, to ensure that township economies benefit from global markets and achieve their full potential.

Recently, video surveillance systems have evolved from expensive, human-operated monitoring systems that were only useful after the crime was committed to systems that monitor 24/7, in real time, and with less and less human involvement. This is partly due to the use of smart cameras, the improvement of the Internet, and AI-based algorithms that allow the classifying and tracking of objects in images and in some cases identifying them as threats. Threats are often associated with abnormal or unexpected situations such as the presence of unauthorized persons in a given place or time, the manifestation of a different behavior by one or more persons compared to the behavior of the majority, or simply an unexpected number of people in the place, which depends largely on the available information of their context, i.e., place, date, and time of capture. In this work, we propose a model to automatically contextualize video capture scenarios, generating data such as location, date, time, and flow of people in the scene. A strategy to measure the accuracy of the data generated for such contextualization is also proposed. The pre-trained YOLO11n algorithm and the Bot-SORT algorithm gave the best results in person detection and tracking, respectively. Full article

Background and Objectives: Alcohol consumption has been a longstanding public health concern and known link to violence. The aims of this study were to analyze alcohol-related homicide cases in Lithuania, focusing on the prevalence of binge drinking among perpetrators and victims, the situational and behavioral patterns leading to violence, and the legal outcomes of these cases. Materials and Methods: This study employed a retrospective analysis of court case law of criminal cases of the year 2019. The analysis was conducted by combining qualitative and quantitative analytical approaches. Results: The findings revealed that 84.6% of homicides occurred during binge drinking events. Alcohol intoxication was prevalent among both perpetrators (92.3%) and victims (86.5%), emphasizing the dual role of alcohol in homicide cases. Interpersonal violence was the primary pattern of homicide (78.8%), while planned homicides accounted for 21.2%. Thematic content analysis of the cases revealed that Lithuanian courts consistently regard alcohol consumption as an aggravating factor that contributes to the commission of violent crimes and influences the severity of criminal punishment. This reflects a judicial position that voluntary intoxication does not lessen legal responsibility, despite its effects on impairing judgment, heightening aggression and impulsivity, and escalating conflicts into deadly violence. Conclusions: Our findings revealed that the majority of alcohol-involved homicides occurred during binge drinking events, in a domestic environment, and because of unplanned acts of interpersonal violence. Targeted public health interventions should focus on strengthening alcohol control policies and enforcing stricter regulations to discourage binge drinking environments. Full article

Background: Cargo theft represents a persistent challenge to last-mile logistics in the peripheral regions of São Paulo, Brazil, compromising transportation security and increasing operational costs. These high-crime areas disrupt supply chain stability and hinder e-commerce growth. Traditional security methods often fail to address the complexity and uncertainty present in these environments, necessitating adaptive approaches. Methods: This study applies an Expert System based on Paraconsistent Annotated Evidential Logic Eτ to assess the effectiveness of security interventions. Logic Eτ is particularly suited for analyzing uncertain, incomplete, and contradictory data in complex logistics settings. A mixed-methods approach was employed, integrating evaluations from nine experts representing different hierarchical levels within a logistics company. Six key security measures, including GPS tracking, armed escorts, optimized delivery windows, and the hiring of local drivers, were analyzed using favorable degrees and unfavorable degrees for each parameter. Results: The results demonstrated that five measures were effective, contributing to a 58% reduction in security costs in Arujá and 75% in Cajamar, two major distribution hubs. Conclusions: This study highlights the potential of combining Expert Systems and Eτ Logic to enhance cargo transport security, offering a scalable decision support framework for companies operating in high-risk urban regions.

The proliferation of Internet of Things (IoT) devices has facilitated the exchange of information among individuals and devices. This development has introduced several challenges, including increased vulnerability to potential cyberattacks and digital forensics. IoT forensic investigations need to be managed in a forensically sound manner using a standard framework. However, adopting traditional digital forensics tools introduces various challenges, such as identifying all IoT devices and users at the crime scene. Therefore, collecting evidence from these devices is a major problem. This paper proposes a permissioned blockchain integration solution for IoT forensics (PBCIS-IoTF) that aims to observe data transactions within the blockchain. The PBCIS-IoTF framework designs and tests Hyperledger blockchains simulated with a Raspberry Pi device and chaincode to address the challenges of IoT forensics. This blockchain is deployed using multiple nodes within the network to avoid a single point of failure. The authenticity and integrity of the acquired evidence are analysed by comparing the SHA-256 hash metadata in the blockchain of all peers within the network. We further integrate webpage access with the blockchain to capture the forensics data from the user’s IoT devices. This allows law enforcement and a court of law to access forensic evidence directly and ensures its authenticity and integrity. PBCIS-IoTF shows high authenticity and integrity across all peers within the network. Full article

Practical challenges and special threats from scam-related fraud exist for regional and local communities in Southeast Asia during and after the COVID-19 pandemic. The rise in pig-butchering operations in Southeast Asia is a major concern due to the increased use of digital technology and online financial transactions. Many of these operations are linked to organized crime syndicates operating across borders, posing challenges for law enforcement. As a first study in Vietnam, we combined the primary and secondary databases to unveil the nature of transnational scam-related fraud. Findings show that scammers are using advanced methods such as phishing, fraudulent investments, and identity theft to maximize their sophisticated tactics for achieving financial possession. There are organized crime rings operating in Vietnam and Cambodia, with Chinese groups playing a leading role behind the scenes. Social media and its various applications have become common platforms for these criminal activities. This study also calls for practical recommendations to consider specific challenges in combating these crimes, including building a strong framework with clear policies, encouraging multiple educational awareness campaigns in communities, enhancing effective cooperation among law enforcement and others, and supporting evidence-based approaches in research and application. While we recognized and assumed that pig-butchering operations with scam-related fraud are a complex problem that requires a well-rounded and coordinated response, the exact approach would depend on each country’s specific circumstances.

In Rwanda, following the 1994 Genocide against the Tutsi, many people were found guilty of genocide crimes and imprisoned. Their children ended up in a situation of ambiguous loss during and after a parent’s imprisonment. The article presents the multidimensional impact of this loss on the everyday lives of these children and their families according to key themes as they emerged from an ethnographic study in which 21 children and their family members participated. Themes include changed family dynamics and family stress, economic deprivation, incomprehension of a parent’s criminal past, the social stigma of being a child of a génocidaire, and strategies used to make the loss bearable. The uniqueness of the ambiguous loss as experienced by children of perpetrators of genocide in Rwanda compared to those of perpetrators of the Holocaust or other mass crimes relates to an amalgam of factors specific for the context of post-genocide Rwanda; major ones being the severity of genocidal crimes and gacaca courts Rwanda chose as its main form of transitional justice. The case study illustrates how using the prism of intergenerational relations helps to understand some of the transformative and enduring effects of a crisis that deeply affects a society.

This article examines the challenges posed by criminal subcontractors in the construction industry. It aims to delineate the specific crimes committed by these subcontractors and assess their impact against the broader backdrop of industry-related criminality. Employing a scoping literature review, the study explores the existing research, summarizes key findings, and highlights gaps in the current knowledge. The construction industry’s inherent complexities and reliance on extensive subcontracting create an environment ripe for criminal activities. The research questions addressed are the following: (1) What crimes are carried out by subcontractors? (2) What are the consequences of crimes carried out by subcontractors? This study identifies several major concerns: (1) adverse impacts on project management in terms of timelines, quality, and budgetary control; (2) widespread exploitation within supply chains, ranging from wage disparities to modern slavery; (3) prevalent fraudulent practices, such as bribery, collusion, and embezzlement; and (4) the detrimental effect on Health, Environment, and Safety (HES) standards. The article underscores the diversity of legal frameworks across jurisdictions and signals the need for concerted efforts to enhance crime prevention measures, foster industry-wide collaboration, and establish robust control systems. There is an urgent need for a profound understanding of the contractor–subcontractor dynamic and procurement of substandard materials. The findings suggest that the construction industry faces formidable challenges due to criminal elements, profoundly affecting project efficiency, legal compliance, and worker welfare. Full article

Authorities and civilians can make a report-of-concern to Social Services if they suspect a child is experiencing or witnessing violence. In 2021, Sweden implemented new legislation that considers children as victims of crime not only when abused but also when witnessing family violence, i.e., Barnfridsbrott. This study aimed to describe and analyze reports-of-concern regarding children witnessing family violence. Are there any changes in number of reports over the years? Who is reporting? And what interventions are most frequent? This is a register-based study of reports-of-concern in Gävle municipality in Sweden for the years 2018–2022. This unique register makes it possible to identify and follow up reported cases as long as they are active by Social Services. Results show there was already a major increase in the number of reports-of-concern in 2020. Most reports are made by Social Services and the police. Of all reports related to family violence, an increasing number lead to further investigations. In most of those cases, the children stay with their families, and Social Services offer counselling. Conclusion: there was a distinct increase in reports related to children witnessing family violence already starting in 2020 in the studied municipality, before the new legislation was implemented.
