Marksmanship data is a staple of military and law enforcement evaluations. This ubiquitous nature creates a critical need to use all relevant information and to convey outcomes in a meaningful way for the end users. The purpose of this study is to demonstrate how simple simulation techniques can improve interpretations of marksmanship data.

This study uses three simulations to demonstrate the advantages of small arms combat modeling, including (1) the benefits of incorporating a Markov Chain into Monte Carlo shooting simulations; (2) how small arms combat modeling is superior to point-based evaluations; and (3) why continuous-time chains better capture performance than discrete-time chains.

The proposed method reduces ambiguity in low-accuracy scenarios while also incorporating a more holistic view of performance as outcomes simultaneously incorporate speed and accuracy rather than holding one constant.

This process determines the probability of winning an engagement against a given opponent while circumventing arbitrary discussions of speed and accuracy trade-offs. Someone wins 70% of combat engagements against a given opponent rather than scoring 15 more points. Moreover, risk exposure is quantified by determining the likely casualties suffered to achieve victory. This combination makes the practical consequences of human performance differences tangible to the end users. Taken together, this approach advances the operations research analyses of squad-level combat engagements.

For more than a century, marksmanship evaluations have used point-based systems to classify shooters. However, these scoring methods were developed for competitive integrity rather than lethality as points do not adequately capture combat capabilities. The proposed method thus represents a major shift in the marksmanship scoring paradigm.

This study aims to investigate the clamour by the people of Plateau State, Nigeria, for more licences to bear firearms for self-defence because of the continuous failure of the Nigerian State to defend them against the Fulani herders’ aggression. More guns less crime deterrence theory served as the framework of analysis, which posits that because criminals are rational beings, they will choose not to attack when they know many people have legitimate firearms.

Data were collected from four purposefully selected local government areas of the state. This study’s sample size was 400. Therefore, 400 copies of the Google Forms questionnaire were administered. In addition, seven key informant interviews and nine focus group discussions were also conducted.

This research results showed the following: while self-defence and issuance of more licenses were supported by 84.8% and 85.0% of respondents, respectively, they also argued that the insurgency would likely end if more people carried legally acquired firearms. Again, the study showed a positive correlation between the government’s failure in security and the demand for self-defence exercises against the Fulani herdsmen’s insurgency, this study recommends more licensed firearms for the people of Plateau State.

This study recommends more licenced firearms for the people of Plateau State.

The focus of the current study is to assess whether officers' broad attitudinal orientations are linked with their situational perceptions of danger in various armed citizen encounters.

The authors draw on survey data from 672 officers employed at a large metropolitan police department. The police culture literature is used to inform measures of occupational stress, danger, citizen distrust, views of upper management, and role orientation in relation to how officers perceive danger across a series of scenarios involving armed citizens that varied in terms of firearm placement and citizen resistance. Along with a host of control variables, a series of multivariate models are used to evaluate the degree to which these aggregated cultural views may shape officers' situational perceptions of danger.

The results indicate that a stronger endorsement of broad attitudinal orientations involving occupational danger and citizen distrust are linked with higher perceptions of danger in armed-citizen encounters, especially as the situations become more discretionary.

Empirical research related to police culture has typically relied upon highly aggregated assessments of how officers view their occupational and organizational work environments. However, yet to be explored is whether these broad views impact officers' assessments of specific encounters, particularly those that are dangerous in nature. The findings from this study also have the potential to inform ambiguous use of force standards that are heavily influenced by officers' situational assessments of danger.

The purpose of this research paper is to review and synthesize the role of blockchain technology (BCT) in various types of illegal activities, including but not limited to fraud, money laundering, ransomware attacks, firearms, drug tracking, cyberattacks, identity theft and scams.

The authors conducted a review of studies related to illegal activities using blockchain from 2015 to 2023. Next, a thematic review of the literature was performed to see how these illegal activities were conducted using BCT.

Through this study, the authors identify the relevant themes that highlight the major illegal activities performed using BCT, its possible steps for prevention and the opportunities for future developments. Finally, the authors provide suggestions for future research using the theory, context and method framework.

No other research has synthesized the illegal activities using BCT through a thematic approach to the best of the authors’ knowledge. Hence, this study will act as a starting point for future research for academic and technical practitioners in this area.

Football supporters have safety and security guarantees, but protection rights abuses in the Kanjuruhan Indonesia stadium tragedy. This study aims to create a design regulation to protect the protection rights of football supporters in the world.

This is a socio-legal study. The law, cases and conceptual methods are the research methodologies. The process of collecting data uses a literature review. The gathered facts and information are next examined both qualitatively and descriptively.

The tragedy that occurred at the Kanjuruhan Stadium is the worst tragedy of Indonesian football. The key factor behind the tragedy was the mechanism for securing football matches regulated in the acts and regulations in Indonesia, which were out of sync and contrary to Federation Internationale de Football Association (FIFA) regulations. The Indonesian National Police Regulation (Perkapolri) permits the use of firearms, tear gas and force, whereas this is actually prohibited by the FIFA Stadium Safety and Security Regulation (FSSSR). In this tragedy, protection rights abuses occurred. Then, the Indonesian Sport Act (ISA) 2022 does not yet regulate crucial matters, especially safety and security in sports competitions to protect players, referees, spectators/supporters and other match organizers.

This study examines various regulations relating to sports, especially football matches with a focus on studies in Indonesia.

The results of this research help realize protection rights for football supporters and create designs regulation to protect protection rights for football supporters worldwide.

The design regulation recommended in this study is useful for preventing disasters in football and protecting football supporters, players, referees and parties in matches from acts of violence.

Learning from the Kanjuruhan tragedy, to prevent this from happening again, the adoption of the FSSSR into Indonesian legislation, created the Safety of Sports Grounds Act and the establishment of the Indonesian Football Policing Unit are recommendations that need to be considered.

The purpose of this study is to explore the ideological gaps on police use of force.

In a national-level survey distributed via Mechanical Turk (MTurk) (n = 979), the authors explore the role that respondents' political ideology plays in the approval of police use of force across a range of scenarios.

Across all scenarios, self-identified conservative respondents maintain strong approval of police use of force. In comparison, liberal respondents provide more variance in their views on approval of police use of force based on the scenario. The scenarios where there are small gaps in approval between the two ideologies are when reasonable force is used toward a violent threat.

There are specific circumstances where the messaging surrounding use of force can create agreement (reasonable) or disagreement (excessive) among conservatives and liberals.

Conservatives and liberals demonstrate gaps across an even larger set of use of force scenarios.

Policing requires atypical work hours. The present study examined associations between shiftwork and pregnancy loss among female police officers.

Participants were 91 female officers with a prior history of at least one pregnancy. Shiftwork information was assessed using daily electronic payroll work records. Any prior pregnancy loss (due to miscarriage) was self-reported. Logistic regression estimated odds ratios (OR) and 95% confidence intervals (CI) for main associations.

On average, the officers were 42 years old, had 14 years of service, and 56% reported a prior pregnancy loss. Officers who worked dominantly on the afternoon or night shift during their career had 96% greater odds of pregnancy loss compared to those on day shift (OR = 1.96, 95% CI:0.71–5.42), but the result was not statistically significant. A 25% increase in percent of hours worked on night shift was associated with 87% increased odds of pregnancy loss (OR = 1.87, 95% CI:1.01–3.47). Associations were adjusted for demographic and lifestyle factors. Objective assessment of shiftwork via electronic records strengthened the study. Limitations include small sample size, cross-sectional design and lack of details on pregnancy loss or the timing of pregnancy loss with regard to shiftwork.

The present study is preliminary and cross-sectional.

With considerable further inquiry and findings into this topic, results may have an impact on police policy affecting shift work and pregnant police officers.

Implication on the health and welfare of police officers.

To our knowledge, there are no empirical studies which associate shiftwork and pregnancy loss among police officers. This preliminary study suggested an association between shiftwork and increased odds of pregnancy loss and points out the need for further study.
