RESUMEN

PURPOSE: It is essential to regulate nursing to protect the population's health. As regulation constantly changes in response to societal trends, periodic reviews of nursing regulations become imperative. Therefore, we developed a legal framework by extracting essential elements for nursing regulation and explored its potential application. METHODS: This study consisted of two parts. First, the legal framework for nursing regulation was developed through reviewing literature that mentions the content that can be included in nursing regulations, and through a content validity assessment by five experts. Second, this legal framework was applied to the nursing laws of China, Hong Kong, Japan, and Taiwan to confirm the suitability of the framework. RESULTS: In the first part of the study, the legal framework for nursing regulation consisting of seven categories (purpose, definitions, standards for practice, license acquisition and registration to practice, regulatory body, protection of the legal authority of nurses, offences/penalties and disciplinary procedures) and 17 items was developed. As a result of applying this framework to nursing laws in four countries, the average utilization rate for all 17 items was 68.4%. The matching scores between the framework and the law were over 60% for all four laws. CONCLUSION: Regulations, especially in the form of legislation, must be carefully considered because laws involve enforcement and potential penalties. This study is significant for identifying essential nursing regulation elements and offering a practical reference tool, expected to be widely utilized in future nursing policy and regulatory research.

RESUMEN

Advanced driver-assistance systems (ADAS) are technologies that can enhance drivers' safety by relieving them from some driving related activities. However, police driving conditions and demands are different from those of civilian drivers. The objective of this study was to assess the impact of ADAS such as forward collision warning (FCW), automatic emergency braking (AEB), and blind spot monitoring (BSM) on police officers' driving performance, workload, and trust in vehicle safety to provide personalised solutions for police vehicles. A driving simulation study was conducted with 18 police officers. ADAS use was assessed under various driving conditions and while officers were engaged in non-driving related tasks. Findings suggested that the FCW and AEB systems improved officers' driving performance, while the BSM system had limited effectiveness due to low salience. ADAS were beneficial under normal driving conditions and when officers were using in-vehicle technology; however, they did not help officers in pursuit conditions.


A driving simulation study was conducted to assess the effect of ADAS in police vehicles under various driving and non-driving related task conditions. The results can help vehicle manufacturers improve the design and usability of ADAS in police cars.

RESUMEN

The COVID-19 pandemic has exposed and exacerbated existing disparities in various societies. This study investigates disparities among racial, ethnic, and linguistic groups in Hong Kong's society in COVID-19 infection rates and lockdown enforcement practices that was imposed 545 times from January 2021 to September 2022 and affected 9% of the population. It is found that neighborhoods with more white individuals had lower infection rates than the overall population, while those with more ethnically minoritized groups had higher infection rates. Furthermore, hit rate tests reveal that the government targeted more neighborhoods with a higher share of individuals from linguistically minoritized groups. This novel finding suggests that not only race, but linguistic difference of the same ethnicity can cause bias. The study highlights the positive impact of providing ethnic support services on health outcomes in neighborhoods with a higher share of individuals from ethnically minoritized groups.

RESUMEN

The objectives of this prospective study were to explore the health-related lifestyle of police cadets and assess changes in their health behaviors following entry into the police force. To do so, 190 police cadets completed an online questionnaire assessing their physical activity level, sedentary behaviors, diet quality, sleep hygiene, alcohol consumption, cigarette smoking, and stress level. One year following their graduation from the police training program, participants were invited to, once again, complete the questionnaire. Our results suggest that police cadets generally display healthy lifestyles, with very few cadets being physically inactive, smokers, reporting insufficient sleep duration, and displaying obesity. Nevertheless, paired-sample comparisons highlighted significant decreases in physical activity, fruit and vegetable intake, sleep duration, and sleep quality at the follow-up. Likewise, significant increases in fast-food consumption and BMI were observed.

RESUMEN

BACKGROUND: In Australia, there is a lack of research on the impacts on law enforcement officers (LEO) and agencies (LEA) working with families impacted by child sexual abuse. PartnerSPEAK is the only Australian specialist not-for-profit, peer-led agency advocating for the secondary victims or non-offending partners and affected family members (NOP/AFM) of those who engage in the online sexual exploitation of children (OSEC). OBJECTIVE: This research explores the interactions between Australian specialised OSEC LEO and the perpetrators of NOP/AFM in OSEC and how these impact well-being and investigative efficacy. SETTING AND PARTICIPANTS: This research surveyed 48 Australian OSEC specialist investigators online from within the Australian Federal Police, Border Force, and local law enforcement agencies. DESIGN: This study employed a mixed-method design, including quantitative scaled responses and qualitative open-ended questions through an online survey. RESULTS: The results showed investigators reported responding to families as more distressing than viewing OSEC. Additionally, positive relationships with NOP/AFM enhanced well-being and justice outcomes. However, given the research design, methods, and sample size, we could not determine statistical significance from the findings. CONCLUSIONS: Responding to non-offending family members is not an adjunct to the investigator's role but is an integral part of OSEC investigations. Therefore, we recommend that law enforcement leadership prioritise improving the procedures and well-being of investigators and non-offending family members impacted by OSEC investigations. This study provides the first evidence in examining this topic and, as such, has meaningful practice implications for law enforcement and opportunities to build on these findings.

RESUMEN

Ryan Gainer, a 15-year-old African-American youth on the Autism-spectrum, was shot and killed by police officers in March 2024. The authors reflect on the tragedy of this incident and the harms that such police actions inflict on people living with disabilities and/or mental illnesses, as well as on their families, loved ones, and communities. Drawing on past research and similar incidents in recent years, the authors offer a series of systematic changes which may be effective in reducing the frequency and severity of police use of force on people on the autism spectrum.

RESUMEN

Working dogs are an essential part of modern society, and police canines (K9s) in the United States are amongst the most recognizable of all working dogs. Given the dearth of published data on active police canines in the U.S. and the calls for police reform, an interdisciplinary effort is necessary to comprehensively understand how these dogs are best used for the benefit of society. This review paper relies on veterinary public health expertise to present a comprehensive overview of police canine use by municipal law enforcement in the United States, including known impacts and gaps in knowledge. The existing literature from animal-assisted interventions (AAI) provides evidence to ensure working dog well-being, while human-animal bond research contributes to officer safety and canine partnership. Lastly, law enforcement and public health agendas (LEPH) assure the team's successful efforts in built environments and local neighborhoods. These frameworks acknowledge the complexity of police dog use, spanning from punitive to public relations, which mirrors the role of law enforcement in U.S. society. This paper proposes the use of a One Health framework to ensure police canine contributions to society, including suggested approaches to partner municipal police with veterinary medicine and public health, and integrate One Health in promoting public safety for local communities.

RESUMEN

BACKGROUND: Physical fitness is a key tenet of military organisations worldwide. Specifically, many consider aerobic fitness (AF) an essential physical attribute for ensuring optimal military performance and readiness. However, the intricate relationship between AF and various facets of military job performance necessitates comprehensive review to ascertain the appropriateness and effectiveness of its assessment. OBJECTIVE: This narrative review aims to describe the relationship between AF and factors influencing individual military performance and readiness, and explores the implications of the enforcement of in-service, generic AF test standards in military populations. METHODS: Databases (PubMed and Google Scholar) were searched for all relevant published peer-reviewed literature as at August 2023. RESULTS: Inconsistent associations were found between AF and outcomes influencing individual military performance (physical capabilities, cognitive capabilities, presenteeism and productivity, resilience, and technical/tactical capabilities) and readiness (mental health and wellbeing and physical health). Consequently, the level of AF needed for acceptable or optimal military performance remains uncertain. CONCLUSIONS: AF is a cornerstone of health and performance, yet linking generic AF test standards to job performance is complex, with multiple factors interacting to influence outcomes. From existing literatures, there does not appear to be a specific level of AF at, and/or above, which acceptable military performance is achieved. As such, the enforcement of and emphasis on in-service, pass/fail, generic AF test standards in military populations is questionable and requires thoughtful re-evaluation. Role/task-specific AF should be assessed through evidence-based PES and the use of generic AF tests limited to the monitoring and benchmarking of health-related fitness.

RESUMEN

Decades of illegal hunting (poaching) have adversely affected wildlife populations and thereby limited sustainable wildlife conservation in the Luangwa Valley, Zambia. Despite intervention efforts to address the problem, the illegal hunting of wildlife has persisted. Therefore, this study was conducted to understand the persistence of illegal hunting by investigating the drivers of poaching and intervention measures using a mixed methods approach. Stratified random sampling was used to collect data from 346 respondents through structured questionnaires. Purposive sampling was used to collect data through nine focus group discussions and three in-depth interviews with experts. The study revealed that persistent illegal hunting was mainly driven by people's critical need for survival and sustaining their livelihoods and not by inadequate law enforcement as presumed by resource managers. Although law enforcement was the most prevalent intervention measure, it did not deter local illegal hunters because their main motivations for poaching were not effectively addressed. The key implication of these findings is that where the illegal harvesting of natural resources in protected areas by local resource users is driven by people's critical need for survival and a livelihood, which is ineffectively addressed, illegal harvesting may persist even with increased law enforcement. This study provides empirical evidence, novel conceptual knowledge and an understanding of how prevalent drivers of poaching and other factors may have influenced persistent illegal hunting in the Luangwa Valley.

RESUMEN

OBJECTIVE: Aim: To study the study the impact of negative factors of professional activities on the health of law enforcement officers. PATIENTS AND METHODS: Materials and Methods: The research involved 89 law enforcement officers (58 men, and 31 women) who served for a year in practical police units after graduating from a higher educational institution. Methods: analysis and generalization of scientific and methodological literature, anthropometry, physiometry, testing, and statistical methods. The health status was assessed by body mass index, Robinson index, and vital index. RESULTS: Results: It was found that the body mass index of law enforcement officers for one year of service in practical units deteriorated in both men and women by 1.3 kg/m2 and 0.9 kg/m2, respectively. More negative changes were observed in men. At the same time, after one year of service, the number of men with overweight (27.5 %) and even obesity of the first (13.9 %) and second (5.2 %) degrees increased significantly. In women, the changes were less pronounced. The dynamics of Robinson and vital indices, as well as the level of physical fitness, were also negative. CONCLUSION: Conclusions: The results of the research indicate a negative impact of professional factors in terms of professional activities on the health of law enforcement officers. It has been found that adherence to the principles of a healthy lifestyle, in particular, a regimen of rationally organized motor activity, is an important area in combating the impact of negative factors of professional activities on the health of law enforcement officers.

RESUMEN

OBJECTIVE: Aim: To determine the effectiveness of physical therapy on the functional state of law enforcement officers' knee joints after surgical intervention. PATIENTS AND METHODS: Materials and Methods: The research involved law enforcement officers from different units of the National Police of Ukraine (n = 56) who had suffered knee joint injuries in the line of duty, and underwent surgical intervention and rehabilitation procedures. RESULTS: Results: It was found that 78.2 % of respondents had suffered knee joint ligament injuries as a result of falls during rapid movement, while 43.9 % were in full gear (armored protection, helmet, etc.). It was determined that after surgical intervention, the functional state of the knee joint of law enforcement officers who followed the recommendations of physical therapy specialists and systematically performed special sets of physical exercises was significantly different (p < 0.001). Worse results were noted in people who partially followed the recommendations of rehabilitation therapists and performed part of the prescribed procedures and physical exercises. CONCLUSION: Conclusions: The effectiveness of the complex use of physical rehabilitation means for restoring the functioning of the knee joint after surgical intervention, which included arthroscopy, partial menisectomy of the damaged areas, debridement, vaporization of damaged cartilage, etc. was revealed. The positive effect of physical exercises on the functional state of the knee joint was proven. The sets of exercises that are advisable to use to restore the functioning of the knee joint were determined.

RESUMEN

OBJECTIVE: Aim: To investigate the dynamics of law enforcement officers' physical and mental health components while performing their duties during the war in Ukraine. PATIENTS AND METHODS: Materials and Methods: The research, which was conducted in 2022-2024, involved 114 law enforcement officers (male) from the Kharkiv oblast (Ukraine) of different ages: under 30 (n = 35), under 40 (n = 41), over 40 (n = 38). To test law enforcement officers' physical and mental health indicators, we used 3 methods: 1) "Fatigue-Monotony-Oversaturation-Stress"; 2) "Well-being-Activity-Mood"; 3) "Assessment of Nervous and Emotional Stress". RESULTS: Results: The negative dynamics of most components of the physical and mental health of law enforcement officers of all three groups while performing their duties during the martial law were revealed. The most pronounced significant changes occurred in such components as "Fatigue", "Oversaturation", "Stress", "Well-being", "Mood", "Nervous and Emotional Stress". The most pronounced negative changes in most components occurred in law enforcement officers over 40 years old, which is due to both the age characteristics of the subjects and their length of service. CONCLUSION: Conclusions: The research confirms the high complexity and extremity of law enforcement officers' service activities during the martial law, as well as the high requirements for law enforcement officers' readiness to perform tasks in the context of a significant expansion of the National Police's powers. The results obtained also necessitate the search for effective ways to preserve and maintain the physical and mental health of law enforcement officers.

RESUMEN

OBJECTIVE: Aim: To study the attitude of law enforcement officers to motor activity and investigate its impact on their health. PATIENTS AND METHODS: Materials and Methods: The research, which was conducted in 2022-2024, involved 163 law enforcement officers under the age of 30. Research methods: bibliosemantic, questionnaire, testing, medical and biological methods, methods of mathematical statistics. RESULTS: Results: It has been found that the vast majority of law enforcement officers (85.3 %) understand the importance of motor activity as a factor of a healthy lifestyle, its impact on physical and mental health, and quality of their professional activities. At the same time, only 27.6 % of law enforcement officers systematically engage in motor activity, 52.8 % do it sporadically, and 25.8 % do not engage in it at all. Among the reasons that prevent them from exercising are lack of time (65.6 %), lack of desire (31.3 %), and fatigue after a service day (28.1 %). It has been found that law enforcement officers who systematically engage in motor activity have a significantly better level of health (7.31 points) compared to those who engage in occasional motor activity (5.07 points) and do not engage at all (2.19 points). CONCLUSION: Conclusions: The positive impact of motor activity on the level of health of law enforcement officers has been proved. Good health is a guarantee of high resistance of law enforcement officers to negative factors of professional activities, professional longevity, and quality of their professional tasks.

RESUMEN

Protected area management often depends heavily on law enforcement to secure compliance with rules. However, this can contribute to conflict between protected area authorities and local people, negatively affecting both human well-being and conservation outcomes. Compliance is affected by many factors, including whether those who enforce rules are perceived to do so fairly, as well as the perceived rule-related behavior of others. We used factorial survey experiments to explore how fair respondents living around protected areas in Indonesia and Tanzania perceive sanctions distributed by law enforcers to be. We presented scenarios to respondents to assess how crime type, offender characteristics, and corruption influenced their judgments regarding the fairness of administered sanctions. We also assessed how descriptive norms and corruption influenced individuals' willingness to obey protected area rules. Data were collected from 229 people in Indonesia and 217 in Tanzania. Results showed that in both locations, lawful sanctions, such as arrests or warnings, were perceived as fairer, and sanctions that involved corruption were perceived as least fair. Attitudes toward protected area rules, corruption, and descriptive norms all influenced people's willingness to comply, whereas multidimensional poverty did not. Our results highlight the need for conservation policy and practice to move beyond narratives that focus on the need for more law enforcement. To improve protected area compliance and secure better outcomes for people and nature, conservation must focus on ensuring the fair administration of rules and enhancing the legitimacy of rules themselves.


Mejoras en el cumplimiento alrededor de las áreas protegidas mediante la administración imparcial de reglas Resumen El manejo de áreas protegidas casi siempre depende de la aplicación de la ley para asegurar el cumplimiento de las reglas. Sin embargo, esto puede contribuir al conflicto entro las autoridades de las áreas protegidas y los locales, lo que afecta negativamente al bienestar humano y a los resultados de conservación. El cumplimiento se ve afectado por muchos factores, incluido si se percibe que quienes aplican las reglas lo hacen de manera imparcial, así como el comportamiento relacionado a las reglas de las demás. Aplicamos experimentos de censo factorial para explorar cómo los respondientes imparciales que viven en torno a las áreas protegidas en Indonesia y Tanzania perciben las sanciones distribuidas por los agentes de la ley. Les presentamos escenarios para analizar cómo el tipo de crimen, características del ofensor y la corrupción influyen sobre sus juicios con respecto a la imparcialidad de las sanciones administradas. También analizamos cómo las normas descriptivas y la corrupción influyen sobre la voluntad individual de obedecer las reglas del área protegida. Recolectamos los datos de 299 personas en Indonesia y 217 en Tanzania. Los resultados mostraron que, en ambas localidades, las sanciones legales, como arrestos o advertencias, eran percibidas como más justas, y las sanciones que involucraban corrupción eran percibidas como las menos justas. Todas las actitudes hacia las reglas de las áreas protegidas, la corrupción y las normas descriptivas influyeron sobre la voluntad de las personas para obedecer, mientras que la pobreza multidimensional no influyó. Nuestros resultados enfatizan la necesidad de que las políticas y prácticas de conservación vayan más allá de las narrativas que se enfocan en la necesidad de una mayor aplicación de la ley. Para incrementar el cumplimiento en las áreas protegidas y asegurar mejores resultados para las personas y la naturaleza, la conservación debe enfocarse en garantizar la administración imparcial de las reglas e incrementar su legitimidad.

RESUMEN

This article briefly summarizes trust as a multi-dimensional construct, and trust in AI as a unique but related construct. It argues that because trust in AI is couched within an economic landscape, these two frameworks should be combined to understand the dynamics of trust in AI as it is currently implemented. The review focuses on healthcare and law enforcement as two industries that have adopted AI in ways that do and do not engender trust from stakeholders. The framework is applied to both industries to highlight where and why varying trust in AI is observed. Then seven research questions are posed, and researchers are encouraged to test the proposed framework in other AI-reliant contexts, like education and employment.

RESUMEN

BACKGROUND: The increase in online enticement has led to law enforcement agencies engaging in more proactive policing through undercover chat sting operations. OBJECTIVE: We aimed to identify the topics and communication strategies triggering suspicion in chats between law enforcement officers and offenders and why those topics do not result in suspicion in victim-offender conversations. METHODS: We conducted a thematic analysis identifying: (1) how LEOs trigger suspicion, (2) how offenders communicate suspicion, (3) how LEOs attempt recovery from suspicion, and (4) how these triggers were present but did not trigger suspicion in victim-offender chats. We examined 20 LEO-offender chats and 20 victim-offender chats from US ICAC task forces. RESULTS: We identified four themes that triggered suspicion: risk assessment by the LEO's persona, LEO avoidance measures, details related to the offense and evidence, and proof of identity of chat participants. Offender responses to triggers revealed three themes: discomfort navigating boundaries and uncertainty, risk identification, and risk mitigation. Themes for the LEO's responses to suspicion included: risk assessment for chatters, issues with technology, appeasement, and negative emotional reactions. Finally, juxtaposing triggers onto minor-offender chats yielded four themes: explicit boundary setting, victim risk assessment, deep relationship forming and disclosures, and technology issues. CONCLUSION: This study has implications for law enforcement agencies seeking to reduce suspicion and risk assessment by offenders during internet sting operations.

RESUMEN

Introduction: Law enforcement professionals who investigate crimes involving child sexual abuse material face increased risk of mental health challenges, including burnout. This study aims to develop a data-driven self-assessment tool for law enforcement personnel exposed to child sexual abuse material. The tool assesses burnout symptoms and related mental health issues, offering a proactive approach to identifying and supporting individuals at risk. Methods: A mixed-methods investigation involved 500 police investigators and forensic examiners across the U.S. The study utilized a convenience sample recruited through various channels connected with the National Criminal Justice Training Center. Results: Twenty percent of participants exhibited high burnout. The Burnout Self-Assessment Tool demonstrated a sensitivity of 69.6% and specificity of 74.6% at a cut-off point ≥2, correctly classifying 73.6% of the sample. Individuals with scores ≥2 were 3.47 times more likely to be experiencing high burnout than peers with a score of zero, with increasing odds with each additional score. High burnout was associated with longer tenure in current positions. Conclusions: The Burnout Self-Assessment Tool offers a short and simple self-assessment tool for law enforcement professionals exposed to child sexual abuse material, aiding in the early identification of burnout symptoms. A cut-off point ≥2 provides a data-driven strategy for identifying individuals at increased risk, promoting timely intervention and support to mitigate burnout's adverse effects on mental well-being and professional performance. The Burnout Self-Assessment Tool's sensitivity and specificity balance enhances its utility, providing a proactive approach to address the unique mental health challenges faced by law enforcement personnel combating crimes involving child sexual abuse material.

RESUMEN

Ingestion of L-theanine and L-tyrosine has been shown to reduce salivary stress biomarkers and improve aspects of cognitive performance in response to stress. However, there have been no studies to concurrently examine the impact of both L-theanine and L-tyrosine ingestion during a mental stress challenge (MSC) involving a brief cognitive challenge and a virtual reality based active shooter training drill. Thus, the purpose of this study was to determine the impact of ingestion of L-theanine and L-tyrosine on markers of stress and cognitive performance in response to a virtual reality active shooter drill and cognitive challenge. The cognitive challenge involved a Stroop challenge and mental arithmetic. Eighty subjects (age = 21 ± 2.6 yrs; male = 46; female = 34) were randomly assigned L-tyrosine (n = 28; 2000 mg), L-theanine (n = 25; 200 mg), or placebo (n = 27) prior to MSC exposure. Saliva samples, state-anxiety inventory (SAI) scales, and heart rate (HR) were collected before and after exposure to the MSC. Saliva was analyzed for stress markers α-amylase (sAA) and secretory immunoglobulin A (SIgA). The MSC resulted in significant increases in sAA, SIgA, HR, and SAI. Ingestion of L-theanine and L-tyrosine did not impact markers of stress. However, the L-tyrosine treatment demonstrated significantly lower missed responses compared to the placebo treatment group during the Stroop challenge. These data demonstrate that ingestion of L-theanine or L-tyrosine does not impact markers of stress in response to a MSC but may impact cognitive performance. This study was pre-registered as a clinical trial ("Impact of supplements on stress markers": NCT05592561).

RESUMEN

Fitness testing is employed by some law enforcement agencies to assure performance in occupational tasks. The aim of this study was to investigate associations between musculoskeletal fitness assessment scores and performance in police occupational tasks. Retrospective data from 106 law enforcement officers who completed five musculoskeletal fitness assessments (vertical jump (VJ), hand grip strength, leg back dynamometer, 1-minute push-ups and sit-ups) and three routine occupational tasks (1.22m fence jump (FJ), 8.5m victim drag (VD) with 101kg and a get-up (GU)) were collected. A standard multiple regression was performed to determine if the results in fitness assessments were predictive of performance in the occupational tasks. Models combining all fitness assessments significantly predicted performance in FJ (F(5,88)=12.228, p<0.001; adjusted R2=0.38), VD (F(5,88)=9.407, p<0.001; adjusted R2=0.31) and GU (F(5,87)=14.319, p<0.001; adjusted R2=0.42). Further analysis of individual predictors highlighted that performance in the VJ test was a significant contributor for all models, uniquely predicting 15% of FJ (p<0.001), 4% of VD (p=0.03) and 8% of GU (p=0.001) performance. Grip strength uniquely contributed 3% to performance in the VD (p=0.05) and performance in the sit-up test contributed 8% to GU performance (p=0.001). Performance in police-specific occupational tasks requires a combination of muscular strength, power, and endurance. These musculoskeletal fitness components should be ideally assessed in recruitment and return-to work practices to ensure officers can safely and optimally perform their occupational requirements.

RESUMEN

BACKGROUND: Occupational trauma is heightened among police officers due to their exposure to physical, biological, chemical, and psychological hazards. Sustained occupational trauma results in mental illness among members of the police, which is a public health issue of concern. This study aimed to report a scoping review of the literature on strategies employed by police officers for coping with occupational trauma around the globe. METHODS: A search string, formulated from the review question of what is known about the strategies of police officers for coping with occupational trauma, was used to search for articles from databases. A total of 588 hits were screened against inclusion criteria, resulting in 36 full-text studies between 1983 and 2022 being included in this review. Data were extracted using a standardised data extraction tool. The multi-step process was used to analyse the extracted data, integrating quantitative and qualitative approaches. RESULTS: From this review, 'adaptive coping mechanisms', involving confrontation; 'maladaptive coping mechanisms', such as self-isolation, distancing and substance use; 'resilience', relating to mental preparation, and 'seeking support systems' from family, colleagues and professionals reflected the strategies used by police officers to cope with occupational trauma. Social stigma related to mental health disorders impacts the strategies used by police officers to cope with occupational trauma. CONCLUSIONS: the police management and healthcare practitioners must collaborate towards providing constructive environments that support and strengthen police officers' strategies for coping with occupational trauma.
