Abstract
Purpose
The purpose of this paper is to develop a methodology for automatically determining the optimal allocation of police officers in accordance with the division and organization of labor.
Design/methodology/approach
The problem is defined as the problem of the goal programming for which the mathematical model of mixed integer programming was developed. In modeling of the scheduling problem the approach police officer/scheme, based on predefined scheduling patterns, was used. The approach is applied to real data of a police station in Bosnia and Herzegovina.
Findings
This study indicates that the determination of monthly scheduling policemen is complex and challenging problem, which is usually performed without the aid of software (self-rostering), and that it can be significantly facilitated by the introduction of scheduling optimization approach.
Research limitations/implications
The developed mathematical model, in its current form, can directly be applied only to the scheduling of police officers at police stations which have the same or a similar organization of work.
Practical implications
Optimization of scheduling significantly reduces the time to obtain a monthly schedule. In addition, it allows the police stations to experiment with different forms of organization work of police officers and to obtain an optimal schedule for each of them in a short time.
Originality/value
The problem of optimal scheduling of employees is often resolved in other fields. To the authors knowledge, this is the first time that the approach of goal programming is applied in the field of policing.

Abstract
Purpose
The purpose of this paper is to improve the efficiency of accident management from the angle of reducing highway accident response times while taking into account total daily work hours.
Design/methodology/approach
The authors developed a patrol beat scheduling model, which is formulated as a chance-constrained optimization model, with the objective of minimizing the sum of officer work hours. Along with the model, a simulation program was also developed to help evaluate the effectiveness of the model-generated beat schedule in terms of response times.
Findings
This study concluded that, first, the current manually designed beat schedule could be improved should the National Highway Police Bureau adopt the proposed model. Second, the total daily work hours of the model-generated schedule at the confidence level of 100 percent were 64 hours, 21 hours less than the average work hours recorded in the 2006 data, or about an improvement of 24 percent. Should the model be adopted, not only response times will be improved, the 24 percent reduction in work hours could be translated into a cut in personnel cost.
Research limitations/implications
The scheduling model and simulation program are both built upon one-year historical data whose accuracy and completeness is prerequisite.
Practical implications
The proposed model can be adopted by other public service agencies such as fire departments, or emergency service centers. By replacing the historical data used in the study with their own data, agencies can evaluate the efficiency of their existing schedule or generate various schedules based on institutional needs.
Originality/value
This model utilizes historical accident data to generate optimal beat schedule and evaluate the efficiency of such schedule. Similar models have not been found in other studies.

Abstract
Purpose
The purpose of this research is to examine ritualistic humor or joking that exists in a small, rural police department in Western New York.
Design/methodology/approach
Data were collected through participatory observations and interviews during the summer of 2014. Both authors worked in tandem to capitalize on individual expertise to maximize data collection and analyses.
Findings
Results suggest that humor is leveraged by officers to socialize, cope and demarcate authority. Depending on the circumstance, humor can be orchestrated or spontaneous, given the intentions of the officer.
Originality/value
Humor is an important lens through which to view police behavior. The current research underscores the importance of levity as a gauge of organizational and individual health.

This paper aims to provide an in-depth exploration of the code of silence in Korean policing and its relationship to perceptions of disciplinary fairness.
Abstract
Purpose
This paper aims to provide an in-depth exploration of the code of silence in Korean policing and its relationship to perceptions of disciplinary fairness.
Design/methodology/approach
The authors separately surveyed 370 Korean police officers in 2008 and 356 Korean police officers in 2019. The respondents were asked to evaluate seven hypothetical scenarios measuring different types of police misconduct from police corruption to the use of excessive force.
Findings
The results demonstrated that the strength of the code of silence decreased over a decade. The code of silence seems to protect less serious examples of police misconduct more strongly than more serious examples of police misconduct. Furthermore, the extent of the code of silence and perceptions of discipline severity are closely related in situations in which the expected discipline is evaluated by officers as too harsh. When police officers evaluated the expected discipline as fair, they were less likely to adhere to the code of silence than when they evaluated the expected discipline as too harsh, providing support for the simple justice model. On the other hand, the results are mixed for comparisons of the code of silence among respondents who evaluated discipline as fair and those who evaluated discipline as too lenient.
Originality/value
This is one of few studies focusing on the potential changes in the code of silence over time and on its relationship with the perception of disciplinary fairness. South Korea has conducted a reform of the police (the Grand Reform) in the late 1990s and more recently enacted the new laws regulating police misconduct. This study relies on two independent surveys of the same population of police officersto empirically assesses potential changes resulting from these societal and organizational transformations.

The purpose of this study is to examine the contours of police integrity among Korean police officers a decade after police reform was started.
Abstract
Purpose
The purpose of this study is to examine the contours of police integrity among Korean police officers a decade after police reform was started.
Design/methodology/approach
The data were collected in 2009 at the Korean National Police University (KNPU) and the Police Comprehensive Academy (PCA). The questionnaires distributed to police officers contained 14 vignettes describing various forms of police misconduct. The sample consists of 329 police officers, mostly non‐supervisors, attending courses at the KNPU and PCA.
Findings
Results indicate that the contours of police integrity vary across different forms of misconduct. Regardless of whether the respondents' views were measured through questions about misconduct seriousness, appropriate discipline, willingness to report, or knowledge about official rules, the findings suggest that Korean police officers perceived corruption as a serious form of police misconduct, while they considered the use of excessive force to be substantially less serious. In addition, a strong code of silence among the police was detected.
Research limitations/implications
The study examines the contours of police integrity among a convenience sample of police officers from South Korea.
Practical implications
The Korean police administrators interested in controlling police misconduct could utilize this methodology to explore the contours of the code of silence among the Korean police. The results of the study indicate that substantial focus should be put on changing police officer views about the use of excessive force and narrowing the code of silence in general.
Social implications
The results show that the contours of police integrity among South Korean police officers clearly reflect the attitudes and views of the society at large toward corruption and use of excessive force. The lenient attitudes that South Korean police officers have expressed regarding the use of excessive force reflect both the historical attitudes and the lack of clarity of official rules. The strong code of silence is related to the insufficient protection for whistleblowers and the adherence to Confucianism among Korean citizens.
Originality/value
Prior research predominantly measured police integrity as the opposite of police corruption in Western democracies and East European countries in transition. This research expands this by focusing on different forms of police misconduct. In addition, it explores integrity in an Asian democracy with the police agency undergoing extensive reform.

The main objective of the study is to identify the effects of various sources of job-related strains on police managers' turnover intentions.
Abstract
Purpose
The main objective of the study is to identify the effects of various sources of job-related strains on police managers' turnover intentions.
Design/methodology/approach
Data from a sample of American police managers (N = 179) were used to construct a path model that estimated the direct and indirect effect of environmental and organizational stressors on turnover intentions while considering the mediating role of negative emotionality.
Findings
Although most of the surveyed police managers (61%) did not report turnover intentions, those who did were more likely to have experienced burnout, frustration and/or emotional drain. Strenuous relationships with police supervisors and work–life imbalances were the main sources of these negative emotions. Turnover intentions were expressed by managers at the operational/technical level (sergeants) and by those who perceived a lack of procedural justice at the agency level. Highly educated managers were significantly less likely to report burnout and turnover intent.
Research limitations/implications
Since this analysis is based on a relatively small convenience sample of police managers, readers should interpret the results cautiously.
Practical implications
To reduce turnover in police organizations, police administrators should implement and follow policies and procedures to ensure a fair, consistent and just treatment of all employees.
Originality/value
This is one of the few recent studies that focused exclusively on police managers' turnover intentions.

Abstract
Purpose
This paper aims to explore a critical component of the successful transition into a democratic police agency – the state of police integrity – among the Croatian police officers. The paper also analyzes the police officers' views about the community policing efforts.
Design/methodology/approach
The questionnaire administered to police officers in Croatia focuses on various forms of police misconduct, as well as the respondents' views about community policing. A random sample of 811 Croatian police officers was collected at the end of 2008.
Findings
The results of 2008 survey portray a more optimistic picture of integrity of the Croatian police than the results of the 1995 survey did. The respondents in 2008 seem to expect more serious discipline than the respondents in 1995 did. Furthermore, the code of silence – one of the key elements of police integrity theory – seems to be weakening. However, the evaluations of scenario seriousness remain relatively similar, indicating a common hierarchy of seriousness. Finally, the support for the idea of community policing is perceived to be much stronger at the top than at the lower levels of the organizational hierarchy or among individual police officers.
Research limitations/implications
The 1995 and 2008 samples are random samples and thus do not constitute a panel data set.
Practical implications
The methodology can be utilized by police administrators to explore the contours of police integrity in their agencies. More specifically, the administrators can explore whether police officers know the official rules, how serious they evaluate police misconduct, what they think the appropriate and expected discipline is, and how willing they are to tolerate police misconduct in silence.
Originality/value
Prior studies of police integrity focused almost exclusively on one form of police misconduct – police corruption. Following the idea that police integrity encompasses the inclination to resist all temptations (and not just for‐gain ones) to abuse the rights and privileges, the questionnaire used in the study tests the police officers' tendency to resist a variety of temptations and thus yields a more comprehensive picture of police integrity. Furthermore, this methodology enables measurement of the changes in police integrity, which is particularly relevant for a police agency in transition or a police agency undertaking efforts to improve its state of police integrity.

Abstract
Purpose
The purpose of this paper is to illustrate the use of the p-median model to construct optimal patrol areas. This can improve both time spent traveling to calls, as well as equalize call load between patrol areas.
Design/methodology/approach
The paper provides an introduction to the use of integer linear programs to create optimal patrol areas, as many analysts and researchers in the author’s field will not be familiar with such models. The analysis then introduces a set of linear constraints to the p-median problem that are applicable to police agencies, such as constraining call loads to be equal and making patrol areas geographically contiguous.
Findings
The analysis illustrates the technique on simplified simulated examples. The analysis then demonstrates the utility of the technique by showing how patrol areas in Carrollton, TX can be made both more efficient and equalize the call loads given the same number of patrol beats as currently in place.
Originality/value
Unlike prior applications of creating patrol areas, this paper introduces linear constraints into the p-median problem, making it much easier to solve than programs that have non-linear or multiple objective functions. Supplementary code using open source software is also provided, allowing other analysts or researchers to apply the model to their own data.

Abstract
Labour scheduling heuristic methods have been applied in service operating environments using both actual and synthetic demand patterns. Two important characteristics of these demand patterns are (1) demand smoothness and (2) mean demand. Investigates the effects of demand smoothness and mean demand on the solution quality associated with four prominent heuristic methods. Indicates that both characteristics can affect the performance of the heuristic methods. An especially important finding is that the two methods which use information from linear programming solutions are far more robust to changes in the degree of demand smoothness. Concludes that managers should consider linear programming methods as an alternative or supplement for making their scheduling decisions. Also recommends that labour scheduling researchers use multiple levels of mean demand and demand smoothness when evaluating new heuristic methods.
