The social construction of the meaning of acute stressors: A qualitative study of the personal accounts of police officers using a stress counselling service

The police profession is one in which acute stressors are encountered more frequently than in other occupations. Using the personal accounts of 35 police officers attending an in-house stress counselling clinic, the aim of the present study was to provide a qualitative examination of how the institutional context of policing influenced the ways in which acute stressors signified to individual police officers experiencing felt distress. Using the framework of Rational Emotive Behaviour Therapy as an analytical tool, it is argued that beliefs contributing to the experience of felt distress are related to the way in which policing as both an identity and an activity is constructed through the police organizational culture. Not only do these constructions influence the ways in which officers perceive themselves and their environments, but they also operate at the collective level to 'normalize' some emotional responses and to 'pathologize' others which, it is argued, could impact upon the outcomes of interventions such as stress counselling.     

The behaviour of police officers in conflict situations: how burnout and reduced dominance contribute to better outcomes

Dominance plays an important part in police-civilian interactions. However, burnout is associated with a reduction in dominance, and this might, paradoxically, lead to more effective outcomes in conflict situations. There is a lack of knowledge about the effects of burnout in professional practice, and this multi-method study was conducted to better understand these dynamics. It is unique in that it combined self-reported burnout with observed behaviour in interactions with civilians. In this study, the relationships between the imbalance between demands and rewards, occupational burnout and police officers’ behaviour in conflict situations (in terms of dominance and effectiveness) were examined. A questionnaire was used to assess job demands, rewards and burnout among 358 Dutch police officers. In addition, police officers’ interactions with civilians were observed over 122 days. The results of structural equation modelling analyses showed that the imbalance between job demands and rewards was predictive of burnout (emotional exhaustion and depersonalization). Burnout, in its turn, predicted a decrease in dominant behaviour in conflict situations and, consequently, more effective conflict outcomes. These findings show that reduced dominance associated with burnout could in fact have positive consequences for professional behaviour in conflict situations. The benefits of reduced dominance in these situations should be taken into account in the training of professionals.     

Heart rate and blood pressure in male police officers and clerical workers on workdays and non-workdays

Abstract

Male police officers from a city police station in Tasmania (n = 20) and a matched group of clerical workers (n = 20) monitored their heart rate, blood pressure and self-reported levels of stress and arousal over a two-week period. Measurements on workdays during which stressful events occurred were compared to non-event workdays and non-workdays. Two group differences were demonstrated, with the clerical workers reporting higher levels of stress, and the police officers reporting higher levels of arousal. Support was evident for the distinction between workdays and non-workdays, and support was demonstrated for differences between different types of workdays. Evidence suggested that restricting the time frame of such research may lead to results that are inaccurate or inconsistent because workdays differ in content.     

Some law enforcement operations implications of crime seasonality

Criminal justice system policy makers have recently begun to utilize sophisticated techniques of analysis to explore questions of resource allocation and program evaluation.^{1, 2, 6, 8, 10} All too often, however, the benefits of such techniques have been denied to the large proportion of criminal justice units which lack access to extensive computer facilities and large technical staffs. This paper illustrates how one important crime data time series property—seasonal variation— may be adjusted for and utilized with some fairly simple procedures. The police operations and planning implications of the presence of seasonality in crime data are then examined. The authors develop their discussion with reference to seasonal variation in monthly data on major crimes for a large United States urban area, Miami, Florida. The time period of the study is 1949–1972.     

Self-perceived occupational stress and distress in a Scottish police force

Abstract

This paper describes an empirical study (n = 699) of occupational stress in a Scottish police force. The self-perceived stress associated with a variety of organizational and opearational stressors was examined along with the associated distress in the police officers in terms of symptoms of anxiety, somatic complaint, severe depression and social dysfunction. The analysis revealed that in spite of the potential that police work offers for exposure to adverse opeational situations such as violence or death, the highest levels of associated stress lie in relation to organizational factors such as officers' perceptions of staff shortages, inadequate resources, time pressures, lack of communication and work overload. Differential rates of perceived stress are reported accordng to gender, rank and working location. This paper further validates previsous research on stress in British police and addresses the situation from a Scottish perspective.     

Distinguishing traumatic, vicarious and routine operational stressor exposure and attendant adverse consequences in a sample of police officers

Problems in studying occupational stress within the police service are identified and the paucity of work on operational duties as potential stressors are discussed. The present study reports the results of a factor analysis of operational stressors (N = 601 serving British police officers) that revealed three factors: exposure to death and disaster; violence and injury; sexual crime. These were demonstrated to be reliable scales and were included in logistic regression models together with a range of demographic and psychological variables. Models were applied to men and women separately, which showed there to be different predictors of the likelihood of suffering distress (measured by the General Health Questionnaire, GHQ) in terms of the officer's gender and operational role. Overall the model for women officers was better at predicting psychological distress than that for men. These findings are related to aspects of the police occupational culture. Further discussion is offered that conceptualizes police operational stressors as traumatic, routine and vicarious. Finally, some implications are drawn for the provision of stress intervention in the light of this differentiation.     

Burnout,job stress and violent behaviour among Dutch police officers

Much has been published on burnout in the human services. However, despite the extensive literature on job stress in policing, burnout in police officers has rarely been studied. The present study examined stressors in police work, focusing specifically on the lack of reciprocity that officers experience in relations with civilians, colleagues and the police service. It also investigated the relationship between burnout and the attitudes of officers towards violence, as well as to their own use of violence. Dutch police officers (N = 358) completed a self-report questionnaire. The results showed that: (1) organizational stressors were more prevalent than task-related stressors; (2) compared to other service jobs, police officers report a particular profile on the three scales of the Maslach Burnout Inventory (MBI)?a relatively low level of emotional exhaustion,an average level of depersonalization, and a high level of personal accomplishment; (3) burnout is associated with a lack of reciprocity between investments and outcomes in the relations that officers have with citizens, colleagues and their organization; and (4) burnout is positively related to attitudes towards use of violence and the use of violence during the officers' duty.     

Should I Text or Call Here? A Situation‐Based Analysis of Drivers’ Perceived Likelihood of Engaging in Mobile Phone Multitasking

This study investigated how situational characteristics typically encountered in the transport system influence drivers’ perceived likelihood of engaging in mobile phone multitasking. The impacts of mobile phone tasks, perceived environmental complexity/risk, and drivers' individual differences were evaluated as relevant individual predictors within the behavioral adaptation framework. An innovative questionnaire, which includes randomized textual and visual scenarios, was administered to collect data from a sample of 447 drivers in South East Queensland‐Australia (66% females; n = 296). The likelihood of engaging in a mobile phone task across various scenarios was modeled by a random parameters ordered probit model. Results indicated that drivers who are female, are frequent users of phones for texting/answering calls, have less favorable attitudes towards safety, and are highly disinhibited were more likely to report stronger intentions of engaging in mobile phone multitasking. However, more years with a valid driving license, self‐efficacy toward self‐regulation in demanding traffic conditions and police enforcement, texting tasks, and demanding traffic conditions were negatively related to self‐reported likelihood of mobile phone multitasking. The unobserved heterogeneity warned of riskier groups among female drivers and participants who need a lot of convincing to believe that multitasking while driving is dangerous. This research concludes that behavioral adaptation theory is a robust framework explaining self‐regulation of distracted drivers.     

Strategy and the “business portfolio”

In this article the author goes on to develop the conclusion reached in his previous article which appeared in the December edition of Long Range Planning. These conclusions concerned the requirements for strategic success for an individual business, here they are developed into their implications for strategy development in the typical multibusiness company.It is argued that relative competitive position and growth are the two fundamental parameters which must be considered in determining the strategy that an individual business should follow when viewed within the context of the company's overall ‘business portfolio’. The likely patterns of business strategy which will lead to overall corporate success are discussed and contrasted with those which can lead to disaster.The key is that strategies should be made to differ widely from business to business, as a function of the growth and relative competitive position of each business and the company's overall resource position particularly with respect to cash. The ‘across the board’ defensive measures which many companies have adopted in recent years as their response to the pressures of inflation and recession are therefore argued to be singularly inappropriate for the long term. The ‘business portfolio’ concept provides a superior approach for developing the differentiated strategic business objectives which are necessary for any company to make the most of its opportunities.     

Three energy scenarios for the United Kingdom

The general principles of constructing scenarios and using them to explore policy options have been described in an earlier paper¹. This paper summarizes the results of a preliminary examination of the three scenarios described there and referred to as ‘business-as-usual’, ‘technical-fix’ and ‘low-growth’. The investigation departs from conventional discussions of fuel policy in that it emphasizes the management of fuel demand, and the interaction between fuel demand and life-style, rather than emphasizing fuel supply policies. The relationship between life style and fuel demand can be quantified using the methods of energy analysis.² This method is capable of fine disaggregation and relatively high accuracy. However the aim of the studies reported here was to establish the range of feasible options and the types of policies needed to accomplish them. For this purpose high accuracy is not important so considerable data aggregation has been retained. The detailed analyses presented in this paper are estimated to be accurate to ±15 per cent.The first part of the paper sets out the analysis of the base year (1968) on which the future projections are based. This involves explaining the principles of energy analysis and the method of projection used. The next sections examine the three scenarios in some detail, starting with the estimation of fuel demand and then looking at the fuel supply and management policies needed.     

Reflexive sensegiving: An open-ended process of influencing the sensemaking of others during organizational change

In this paper, we contribute to the understanding of how managers engage in efforts to influence the sensemaking of others without prescribing a specific redefinition of organizational reality, and doing this while trying to empower their subordinates. Through observations of leadership conferences and interviews, we followed an attempt to establish a new management philosophy in the Swedish police. The aim of the initiative was to facilitate the development of independent co-workers with little or no hierarchical support. The results show how managers utilize reflexivity in sensegiving to facilitate participants’ sensemaking. We suggest the following definition for reflexive sensegiving: a multivocal process aiming to influence how the sensemaking and construction of meaning evolves. Reflexive sensegiving has four distinctive features: open-endedness, low control over cues given, several sources of cues, and the encouragement of complexity and ambiguity. Our contribution, which has conceptual and theoretical consequences, is centred around new outlooks on the content, agent(s), and process of sensegiving.     

Sample Size Allocation for Food Item Radiation Monitoring and Safety Inspection

The objective of this study is to identify a procedure for determining sample size allocation for food radiation inspections of more than one food item to minimize the potential risk to consumers of internal radiation exposure. We consider a simplified case of food radiation monitoring and safety inspection in which a risk manager is required to monitor two food items, milk and spinach, in a contaminated area. Three protocols for food radiation monitoring with different sample size allocations were assessed by simulating random sampling and inspections of milk and spinach in a conceptual monitoring site. Distributions of ¹³¹I and radiocesium concentrations were determined in reference to ¹³¹I and radiocesium concentrations detected in Fukushima prefecture, Japan, for March and April 2011. The results of the simulations suggested that a protocol that allocates sample size to milk and spinach based on the estimation of ¹³¹I and radiocesium concentrations using the apparent decay rate constants sequentially calculated from past monitoring data can most effectively minimize the potential risks of internal radiation exposure.

A Bayesian Belief Network Model Assessing the Risk to Wastewater Workers of Contracting Ebola Virus Disease During an Outbreak

During an outbreak of Ebola virus disease (EVD), hospitals’ connections to municipal wastewater systems may provide a path for patient waste bearing infectious viral particles to pass from the hospital into the wastewater treatment system, potentially posing risks to sewer and wastewater workers. To quantify these risks, we developed a Bayesian belief network model incorporating data on virus behavior and survival along with structural characteristics of hospitals and wastewater treatment systems. We applied the model to assess risks under several different scenarios of workers’ exposure to wastewater for a wastewater system typical of a mid‐sized U.S. city. The model calculates a median daily risk of developing EVD of approximately 6.1×10⁻¹² (90% confidence interval: 1.0×10⁻¹² to 5.4×10⁻⁹; mean 1.8×10⁻⁶) when no prior exposure conditions are specified. Under a worst‐case scenario in which a worker stationed in the sewer adjacent to the hospital accidentally ingests several drops (0.35 mL) of wastewater, median risk is 5.8×10⁻⁴ (90% CI: 8.8×10⁻⁷ to 9.5×10⁻²; mean 3.2×10⁻²) . Disinfection of patient waste with peracetic acid for 15 minutes prior to flushing decreases the estimated median risk to 3.8×10⁻⁷ (90% CI: 4.1×10⁻⁹ to 8.6×10⁻⁵; mean 2.9×10⁻⁵). The results suggest that requiring hospitals to disinfect EVD patient waste prior to flushing may be advisable. The modeling framework can provide insight into managing patient waste during future outbreaks of highly virulent infectious pathogens.     

New Methods for Resolving Conflicting Requests with Examples from Medical Residency Scheduling

In scheduling medical residents, the objective is often to maximize resident satisfaction across the space of feasible schedules, relative to the many hard constraints that ensure appropriate patient coverage, adequate training opportunities, etc. A common metric of resident satisfaction is the number of time‐off requests that are granted. Simply maximizing this total, however, may lead to undesirable schedules since some requests have higher priority than others. For example, it might be better to grant one resident's request for a family member's wedding in place of two residents’ requests to attend a rugby game. Another approach is to assign a weight to each request and maximize the total weight of granted requests, but determining weights that accurately represent residents’ and schedulers’ preferences can be quite challenging. Instead, we propose to identify the exhaustive collection of maximally feasible and minimally infeasible sets of requests which can then be used by schedulers to select their preferred solution. Specifically, we have developed two algorithms, which we call Sequential Request Selection Via Cuts (Sequential RSVC) and Simultaneous Request Selection Via Cuts (Simultaneous RSVC), to identify these sets by solving two sequences of optimization problems. We present these algorithms along with computational results based on a real‐world problem of scheduling residents at the University of Michigan C.S. Mott Pediatric Emergency Department. Although we focus our exposition on the problem of resident scheduling, our approach is applicable to a broad class of problems with soft constraints.     

A Game Theory Approach for Assessment of Risk and Deployment of Police Patrols in Response to Criminal Activity in San Francisco

An efficient police patrol schedule must ensure the allocation of an appropriate number of officers sufficient to respond to the danger of criminal incidents, particularly in an urban environment, even when the available number of personnel is limited. This study proposes a framework that incorporates two game theory models designed for the allocation of police officers to patrol shifts. In the first step, the interactions of three factors between the criminal and the operation captain are modeled as a zero-sum, noncooperative game, after which a mixed strategy Nash equilibrium method is used to derive the risk value for each district to be patrolled. In the second step, the risk values are used to compute the Shapley value for all 10 districts, for three different threat levels. A fair allocation of police personnel based on the Shapley value is made with a minimum set of personnel deployment costs. The efficacy of the proposed method is verified using openly available data from the San Francisco City Police detailing incidents from the year 2016. The experimental results show that police planners can use this framework to quantitatively evaluate the criminal threat in each district when deciding upon the deployment of patrol officers for three shifts per day.     

Adjustable robust strategies for flood protection

Flood protection is of major importance to many flood-prone regions and involves substantial investment and maintenance costs. Modern flood risk management often requires determining a cost-efficient protection strategy, i.e., one which has the lowest possible long run cost and which satisfies flood protection standards imposed by the regulator throughout the entire planning horizon. There are two challenges that complicate the modeling: (i) uncertainty - many of the important parameters on which the strategies are based (e.g. the sea level rise) are uncertain, and will be known only in the future, and (ii) adjustability - decisions implemented at later time stages need to adapt to the realized uncertainty values. We develop a new mathematical model addressing both issues, based on recent advances in integer robust optimization, and we apply it to the Rhine Estuary - Drechtsteden area in the Netherlands. Our approach shows, among others, that (i) considering 40% uncertainty about the sea level rise leads to a solution with less than 10% increase in the total cost, (ii) solutions taking the uncertainty into account are cheaper in the long run if the ‘bad scenarios’ for the uncertainty materialize, even if the ‘optimistic solutions’ are allowed to be repaired later on, and (iii) the optimal here-and-now investment decisions change when uncertainty and adjustability are included in the model.

Whose company is it? The concept of the corporation in Japan and the west

This article examines the differences in the concept of the corporation and their possible implications for corporate performance, between Japan on the one hand and the United States and Europe (Germany, UK and France) on the other. The Japanese concept is used as the standard against which the other models are compared. The concept of the corporation is defined here as the answer to the question: ‘In whose interest should the firm be managed?’¹ This is the foundation on which corporate governance and the monitoring system for the CEO is built. The analysis is focused on large publicly-held corporations with widely diffused ownership.     

Measurement of the subjective work environment

Abstract

This paper considers the various issues that frame the development and use of measures of the subjective work environment. It begins by questioning the role of the work environment in determining occupational health, and explores the possible mechanisms by which that environment might exert its influence. It concludes that one of the important final common pathways is psycho-physiological in nature, and is rooted in individual perception and cognition and the experience of stress. Important for this model are the concepts of mediation and moderation. The measurement of the subjective work environment has often been idiosyncratic to the study in hand, and there are few well-established measures in common use. It is argued that researchers should be careful when deciding not to use established measures and effectively ‘invent’ their own. In developing new measures, decisions have to be made concerning the nature of the measure along with its ‘granularity’ and complexity. It is also argued that it is important that researchers should follow good psychometric practice in the development of those measures. Suggestions for ‘good practice’ are discussed. Attention is drawn to the issues of reliability and validity, and this paper discusses the role of triangulation in the planning and execution of data collection and analysis. The paper ends by reviewing the recommendations made towards the development and use of measures of the subjective work environment.
