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.

A Pre-Selection-Based Ant Colony System for Integrated Resources Scheduling Problem at Marine Container Terminal

Marine container terminal(MCT)plays a key role in the marine intelligent transportation system and international logistics system.However,the efficiency of resource scheduling significantly influences the operation performance of MCT.To solve the practical resource scheduling problem(RSP)in MCT efficiently,this paper has contributions to both the problem model and the algorithm design.Firstly,in the problem model,different from most of the existing studies that only consider scheduling part of the resources in MCT,we propose a unified mathematical model for formulating an integrated RSP.The new integrated RSP model allocates and schedules multiple MCT resources simultaneously by taking the total cost minimization as the objective.Secondly,in the algorithm design,a pre-selection-based ant colony system(PACS)approach is proposed based on graphic structure solution representation and a pre-selection strategy.On the one hand,as the RSP can be formulated as the shortest path problem on the directed complete graph,the graphic structure is proposed to represent the solution encoding to consider multiple constraints and multiple factors of the RSP,which effectively avoids the generation of infeasible solutions.On the other hand,the pre-selection strategy aims to reduce the computational burden of PACS and to fast obtain a higher-quality solution.To evaluate the performance of the proposed novel PACS in solving the new integrated RSP model,a set of test cases with different sizes is conducted.Experimental results and comparisons show the effectiveness and efficiency of the PACS algorithm,which can significantly outperform other state-of-the-art algorithms.

Prevalence and associated factors of stress, anxiety and depression among emergency medical officers in Malaysian hospitals

BACKGROUND： Demanding profession has been associated with poor psychological health due to multiple factors such as overworking hours and night shifts. This study is to determine prevalence and associated factors of depression, anxiety and stress among medical officers working at emergency department in Malaysian hospitals.METHODS： A cross-sectional study was conducted on 140 emergency department medical officers working at general hospitals from seven Malaysia regions. They were randomly selected and their depression, anxiety and stress level were measured by the 21-item Depression, Anxiety, Stress Scale. RESULTS： The highest prevalence was anxiety （28.6%） followed by depression （10.7%） and stress （7.9%）. Depression, anxiety and stress between seven hospitals were not significantly different （P〉0.05）. Male medical officers significantly experienced more anxiety symptoms than female medical officers （P=0.0022）, however depression and stress symptoms between male and female medical officers were not signi？ cantly different （P〉0.05）. Depression, anxiety and stress were not associated with age, working experience, ethnicity, marital status, number of shifts and type of system adopted in different hospitals （P〉0.05）. CONCLUSION： The prevalence of anxiety was high, whereas for depression and stress were considerably low. Gender was the only factor significantly associated with anxiety. Other factors were not associated with depression, anxiety and stress. Future research should aim to gain better understanding on unique factors that affect female and male medical officers’ anxiety level in emergency setting, thus guide authorities to chart strategic plans to remedy this condition.
