An Evaluation of Suicidality and Its Predictors in Police Officers in Lagos, Nigeria

Background: The many dangers and stressors associated with police work often place police officers at a great risk of a variety of mental health morbidity, including suicidality. The causation of suicidality is multi-dimensional, however, there are insufficient studies which have examined the burden and risk factors of suicidality in Nigerian police officers. Objective: To determine the prevalence and predictors of suicidality among police officers in Lagos, Nigeria. Methods: This was a cross-sectional study of 600 police officers who were selected using a non-probability sampling method. Questionnaires used were: Suicide Behaviour Questionnaire-Revised (SBQ-R), State-Trait Anxiety Inventory (STAI), and a Socio-Demographic Questionnaire. Results: Prevalence of suicidality was 14%, and the predictors of suicidality were: state anxiety (p 0.001), trait anxiety (p 0.001), substance use (p = 0.03), being unmarried (p = 0.03), and female gender (p = 0.02). Conclusion: Suicidality is prevalent among Nigerian police officers, with a higher risk in those who are vulnerable. The creation of government policies and infrastructure which promote mental health in police officers is necessary.

Strategies for Countering Freezing in Police Operational Activities

The term“freezing”refers to an innate defensive reaction characterized by the sudden cessation of all movements(Stote&Fanselow,2004;Eilam,2005).The freezing effect involving a police officer exposes him to a risk to himself and others.Materials and Methods:400 anonymous questionnaires administered to law enforcement personnel in Switzerland were evaluated with the aim of testing their knowledge about the freezing phenomenon.In addition,semi-structured interviews involving police personnel were conducted.The authors also analyzed two cases of police officers who had experienced freezing.Results and Conclusions:From the results obtained,it emerges that freezing is not known to most of the police officers interviewed.Therefore,specific and innovative training seems to be necessary.The authors described the brain mechanisms that are involved in freezing.Innovative integrated training modules have been proposed by applying some neuroscientific knowledge,particularly using the potential of mirror neurons.The authors propose a strategy for supporting police officers who have experienced an episode of freezing.The ultimate goal is to provide more scientific tools to protect police officers and civilians.

Assessing the Spatial Equality of COVID Testing Sites Maintaining Zero COVID Policy

Rapid and timely testing is essential to minimize the COVID-19 spread. Decision makers and policy planners need to determine the equal distribution and accessibility of testing sites. This study mainly examines the spatial equality of COVID-19 testing sites that maintain a zero COVID policy in Guangzhou City. The study has identified the spatial disparities of COVID testing sites, characteristics of testing locations, and accessibility. The study has obtained information on COVID testing sites in Guangzhou City and population data. Point pattern analyses, Euclidian distance and allocation, and network analyses are the main methods used to achieve the research objectives, and 1183 total COVID testing sites can be recognized in Guangzhou City. Results revealed that spatial disparities could be noticed over the study area. Testing locations of Guangzhou City are highly clustered. The most significant testing sites are located in Haizhu District, which has the third largest population. The highest population density can be identified in Yuexiu District. However, only 94 testing sites are located there. According to all the results, higher disparities can be identified, and a lack of testing sites is located in the north part of the study area. Some people in the northern part have to travel more than 10 km to reach a testing site. Finally, this paper suggests increasing the number of testing sites in the north and south parts of the study area and keeping the same distribution, considering the area, total population, and population density. This kind of research will be helpful to decision-makers in making proper decisions to maintain a zero COVID policy.

Accessibility and Fairness of Public Service Facilities from the Perspective of Supply and Demand Coordination: A Case Study of Old Urban Area of Guangzhou City

The accessibility and fairness of public service facilities are important manifestations of the convenience and equality of urban public service resource allocation.Optimizing the layout of urban public service facilities is an inevitable requirement for promoting the construction of people centered cities.This paper takes the old urban area of Guangzhou as the research area,measures the accessibility of multiple types of public service facilities based on an improved two-step floating catchment method,and combines Palma Ratio and location quotient methods to explore the fairness of urban public service facilities from two dimensions:social equity and spatial equity,with supply and demand relationship analysis as the main line.Research has shown that:①there is a significant spatial difference in the accessibility of public service facilities in the old urban areas of Guangzhou,and the comprehensive accessibility is generally higher in the central and southeastern regions of the old urban areas with fewer residential populations;②from the perspective of social equity,the resource allocation of public service facilities in the old urban areas of Guangzhou is in a seriously unfair state(with a fairness index of 2.99),and there are also varying degrees of unfairness within the streets;③from the perspective of spatial equity,the location quotient of public service facilities in the old urban areas of Guangzhou shows a pattern of multil center circles decreasing,indicating a significant spatial mismatch between the accessibility supply side of public service facilities and the demand side of the residential population.The research conclusion will provide scientific basis for optimizing the allocation of urban public service facilities and ensuring the equalization of public services.

Police Emergency Commitment Powers in Cases of Persons Experiencing Mental Health Crisis in “Public Spaces”: Review of the Commitment Process in England and Wales, in Comparison to the Practice in the United States of America (USA)

Police emergency commitment powers for detention of persons in the community perceived to be seriously mentally ill for further specialist examination in a designated facility have always raised interest in medical and legal circles on both sides of the Atlantic. The objective of this article is to detail the police commitment procedure in England and Wales, as dictated by the mental health act of 1983 (MHA 1983) amended in 2007 (MHA 2007);and compare this with similar legal provisions as prevails under current state mental health statutes in the United States of America (USA). The comparative review of the commitment processes in England and Wales to that of the USA reveals that the process in England and Wales seeks to primarily ensure that persons with mental disorder (PWMD) in crisis are directed to a specialist hospital for evaluation and appropriate specialist care. In the USA such persons in a good number of cases may end up in the criminal justice system due to application of the “dangerousness” standard. Additionally whereas in England and Wales the commitment law is uniform in law and application, the federal system in the USA is such that the commitment law may have minor variations depending on the individual states. The minor variation in state commitment laws may engender a situation where the commitment law in England and Wales may seem relatively equitable and just towards PWMD in crisis, compared to the state commitment laws in the USA.

Perceptions of People on Police Efficiency and Crime Prevention in Urban Areas in Malaysia

Crime cases from snatch thefts to murders, are becoming increasingly common in Malaysia according to the database of the Royal Malaysian Police （RMP）, the current overall Crime Index in Malaysia was 147,062 for 2013 compared with 65,237 in 1977. The database also revealed that the number of property crimes reported in this country has always exceeded the number of violent crimes. Although in 2013, crimes related to property are higher （117,687） than violent crime （29,375）, the gradual increase in the latter does worry Malaysians. Likewise, Malaysian Government had implemented a ＂safe community＂ concept, inspired by the Malaysian Crime Prevention Foundation （MCPF）, a non-government organization, as they were concerned that the threat of violent crime and non-violent crime would eventually reduce the quality of life for many individuals. The concept is very important to the public as it is perceived as improved safety for the public with less crime. This study analyzes the public safety through their perceptions on the effectiveness of the policeman and suggesting few prevention actions against crime. The data were collected using a self-administered survey questionnaire. Specifically, this study focuses on the more developed states in this country. From the cross tabulation analysis, the majority of respondents agreed that the police are effective in controlling crime. Approximately, 72.1% of respondents felt that the police are efficient in controlling crime.
