De‐controlling the fire service

Everyone is in favour of getting rid of unnecessary central government controls. The fire service offers an opportunity to do just that.     

Twenty‐five years of the Taffler z‐score model: Does it really have predictive ability?

Although copious statistical failure prediction models are described in the literature, appropriate tests of whether such methodologies really work in practice are lacking. Validation exercises typically use small samples of non‐failed firms and are not true tests of ex ante predictive ability, the key issue of relevance to model users. This paper provides the operating characteristics of the well‐known Taffler (1983) UK‐based z‐score model for the first time and evaluates its performance over the 25‐year period since it was originally developed. The model is shown to have clear predictive ability over this extended time period and dominates more naïve prediction approaches. This study also illustrates the economic value to a bank of using such methodologies for default risk assessment purposes. Prima facie, such results also demonstrate the predictive ability of the published accounting numbers and associated financial ratios used in the z‐score model calculation.     

Framing risks in a safety‐critical and hazardous job: risk‐taking as responsibility in railway maintenance

In risk management research, risk‐taking is mostly treated as deviation that calls for improved risk communication. I argue, however, that risk‐taking should be seen as expressing a rationale of its own; thus, improving safety requires that this rationale be adequately understood and that the conditions that reproduce risk‐taking be changed. This argument is supported by an ethnography of railway maintenance in Sweden. Railway technicians are charged with maintaining the railway infrastructure to support safe and punctual trains, an assignment that exposes them to occupational hazards. The technicians' claim of occupational responsibility for transportation safety risks is framed by two notions in occupational discourse: first, the safety‐critical nature of their tasks, and second, the notion of service to the general public. Technician interdependence in achieving occupational safety requires mutual responsibility in the team. Technicians justify occupational risk‐taking, claiming it is sometimes needed to achieve production goals given the available time and resources and the manageability of the risks taken. Finally, I stress the need for technicians to change their frames of reference and for employers to assume responsibility for reducing the need for risk‐taking.     

The effects of risk‐taking tendency on risk choice and pre‐ and post‐decisional information selection

Ideally, people seek and select information about unfamiliar risks with which they are confronted, before they make a risk choice. This study investigated what happens when people do not have this opportunity. The main question was how risk‐taking tendency influences intuitive risk decisions and how this impacts subsequent information search and subsequent choices. In the present study, participants had to make a choice about an unfamiliar risk, either before or after they had had the opportunity to search for (risk‐promoting or risk‐averse) information. In the condition where they could only seek for information after they had made a choice, they had to reconsider their first choice and make a second risk choice. We expected that (1) risk‐taking tendency would impact people's risk choices, but only in the situation where they have little information. On the basis of cognitive dissonance theory, it was furthermore predicted that (2) risk‐taking tendency and (3) initial risk choice would affect risk information selection. Furthermore, we predicted that (4) the first risk choice and (5) the risk information selected would influence the subsequent risk choice. The results suggest that if people make a first, intuitive decision about an unknown risk, risk‐taking tendency has an effect on the choice, but that this does not happen when people can first select information. Risk‐taking tendency did not influence information selection, but initial choice did (although in another way than we expected). Furthermore, both the first risk choice and the risk information selected affected subsequent risk choices. These findings suggest that people often make initial intuitive decisions that are influenced by personality characteristics, and that are subsequently difficult to change.     

Bias in the tone of forward‐looking narratives

We extend the prior literature on biased disclosure decisions by examining whether, when and how managers bias the tone of forward‐looking narratives. In order to measure tone we employ techniques of manual content analysis and we aggregate positive, neutral and negative statements into an overall measure of tone.We then analyse the frequency of positive and negative statements for firms with large impending year‐on‐year changes in sales and operating profit margin, and we regress tone cross‐sectionally on four managerial incentive variables that are unrelated to the private signal about future trading, namely loss status, sign of earnings change, business risk, and the existence of an analyst earnings forecast. We find that firms with large impending performance declines bias the tone in the outlook section upwards. Also, we find that loss firms, risky firms and firms with an analyst earnings forecast provide a more positive tone, while firms with an earnings decline provide a more negative tone. Finally, we observe that for a majority of our managerial incentive variables the main vehicle of biasing the tone is to change the number of negative statements, not the number of positive statements. Overall, our findings are difficult to reconcile with predictions from signalling models, but they are consistent with the alternative view of impression management. Our results have policy implications. In particular, they suggest that there is a need to reconsider the current largely unregulated nature of forward‐looking narratives.     

The effect of pseudo‐immediacy on intertemporal choices

An interesting phenomenon, which we dub the ‘pseudo‐immediacy effect’, was detected in intertemporal choices. The majority of our participants preferred the smaller but sooner (SS) outcome to the larger but later (LL) outcome when a pseudo‐immediacy reward was framed, but a higher proportion of participants preferred the LL outcome to the SS outcome when the pseudo‐immediate format was removed. Such a shift violated the invariance principle which requires that the preference order between options does not depend on the manner in which they are described. With reference to the pseudo‐certainty effect reported by Kahneman and Tversky in 1984 Kahneman, D. and Tversky, A. 1984. Choice, values, and frames. American Psychologist, 39: 341–50. [Crossref], [Web of Science ®] , [Google Scholar], our findings typically support the notion that risk and delay are psychologically equivalent and that the same psychological process underlies risk and intertemporal choice.     

A longitudinal ethnographic study of night‐freight pilots

This paper records the lived reality of night‐freight operations at a UK‐registered airline. Observations were made over an 18‐month period. The paper answers calls for more research into the working and living conditions of night‐freight pilots. Pilots perceived numerous issues. These included cultural cleavage, terms and conditions, roster instability and the impact of night flying on physical and psychological health. Some issues (volatile rosters and deep first nights, for example) had the potential to increase operational risk. Two sub‐cultures were identified within the airline: the quality‐of‐working‐life sub‐culture and competitiveness and corporate survival sub‐culture. A ‘paradox of control’ was observed. While pilots controlled the aircraft in flight, their patterns and conditions of work were decided by roster managers, crewing officers and other office‐based technocrats. Technocrats’ directive power was resented by some pilots. Some claimed that technocrats did not understand the lived reality of the line, resulting in ‘uninformed’ decisions that augmented operational risk. The study involved a single airline. No claims are made for the generalisability of the findings. More studies are required.     

Public Panic and Morale: Second World War Civilian Responses Re‐examined in the Light of the Current Anti‐terrorist Campaign

Following September 11 in the US and July 7 in the UK, the threat to civilians from terrorist attack has become real yet considerable disagreement exists about how people might respond. The effect of aerial bombing on the public's morale during the Second World War and the incidence of psychiatric casualties have been explored to provide reference points for the current terrorist threat. Systematic study of restricted government investigations and intelligence reports into the effect of air‐raids on major British towns and contemporary medical publications have shown that panic was a rare phenomenon and arose in defined circumstances. Morale fluctuated according to the intensity of attacks, preparedness and popular perceptions of how successfully the war was being conducted. Resilience was in part a function of the active involvement of the public in its own defence but also reflected the inability of German bombers to deliver a concentrated attack over a wide area. Most civilians, by their very numbers, were likely to survive. Inappropriate or excessive precautionary measures may serve to weaken society's natural bonds and, in turn, create anxious and avoidant behaviour. Weapons that tap into contemporary health fears have the greatest psychological impact. Efforts by government to engage the public not only build trust but may also make an effective contribution to the campaign against terrorism.     

Evaluating lotteries,risks, and risk‐mitigation programs

Two experiments were designed to explore the existence of systematic differences in risk perceptions and risk attitudes between Chinese and US participants. The first experiment involved ranking monetary lotteries using measures of perceived riskiness and willingness to pay (WTP). Several simple heuristics were evaluated to predict perceived riskiness and WTP. Using WTP responses, Cumulative Prospect Theory functions were determined for participants from both countries. The second experiment involved ranking multi‐attribute real‐world risks and associated risk‐mitigation programs using measures of concern and preference, respectively. Compared to their US counterparts, Chinese participants are found to be less risk averse, more concerned about risks with higher catastrophic potential, and more in favor of risk‐mitigation programs with greater scope of benefit. The results also reveal higher within‐group agreement by Chinese participants for all tasks. For both national groups, the within‐group agreement was highest when ranking risk‐mitigation programs, but lowest when ranking lotteries with negative expected value. The implications of cross‐cultural versus cross‐task variation are discussed.     

Performance measures and short‐termism: An exploratory study

We examine the relationship between performance measurement systems and short‐termism. Hypotheses are tested on a sample of senior managers drawn from a major telecommunications company to determine the extent to which the diagnostic and interactive uses of financial and non‐financial measures give rise to short‐termism. We find no evidence to suggest that the use of financial measures, either diagnostically or interactively, leads to short‐term behaviour. In contrast, we find a significant association between the use of non‐financial measures and short‐termism. Results suggest that the diagnostic use of non‐financial measures leads managers to make inter‐temporal trade‐off choices that prioritise the short term to the detriment of the long term, while we find interactive use is negatively associated with short‐termism. We find an imbalance in favour of the diagnostic use over the interactive use of non‐financial performance measures is associated with short‐termism. Overall, findings highlight the importance of considering the specific use of performance measures in determining the causes of short‐termism.     

Tax‐efficient irregular payout methods: The case of B share schemes and capital repayments via a court‐approved scheme of arrangement

Advance corporation tax (ACT) increased the tax cost to UK firms of distributing cash to shareholders. We demonstrate how the tax cost arising from ACT payments affected the channels through which UK firms returned capital to shareholders. In particular, we document and describe two unconventional irregular payout methods that enabled firms to avoid paying ACT. Firms choosing these methods are associated with significantly greater ACT problems than a control sample of firms that opted for conventional self‐tender offers and special dividends. Event study tests indicate that the decision to adopt tax‐efficient payout methods created significant additional value for shareholders beyond the basic cash distribution decision.     

Defensive capacity: the influence of the facilitation‐regulation space

In their paper ‘Loss of Defensive Capacity in Protective Operations: The Implications of the Überlingen and Linate Disasters’ Busby and Bennett attribute the ‘defensive capacity’ of an airspace system to the behaviour of those who constitute its production‐protection space (first‐line producers like avionics manufacturers, airlines, pilots' groups and airport authorities). This paper argues that an airspace system's defensive capacity is also a function of the behaviour of those who constitute its ‘facilitation‐regulation’ space – the rulemakers (and, to some degree, the non‐statutory bodies who seek to influence them). This elaboration recognises two aspects of regulation. First that some regulators are responsible for promoting both safety and efficiency (the Federal Aviation Administration (FAA) for example). Secondly that regulators who prioritise efficiency over safety may reduce overall system safety and/or create opportunities (affordances) for unsafe behaviour. The argument is illustrated with reference to the National Transportation Safety Board's criticism of the FAA's human factors training programmes for air traffic controllers, its aircraft surface‐movement standards and procedures and its air traffic controller rostering practices following the 2006 crash of a passenger aircraft at Lexington, Kentucky and FAA's implementation of the Traffic Alert and Collision Avoidance System.     

Poxvirus‐vectored Vaccines Call for Application of the Precautionary Principle

Genetically engineered viruses (GEVs) used as live vaccines are, and will increasingly become, important for prevention of disease in human as well as animal populations. Poxviruses have a number of attractive theoretical and practical advantages as gene expressing vaccine vectors: their large genomes render construction of multivalent vaccines feasible, the vaccines are easy to produce, the virus particles are very thermostable, and inoculation is followed by long‐lasting, protective immune responses. On the other hand, administration and environmental release of GEVs may represent potential unintended harms to human, animal and ecosystem health. We will argue that a strict application of risk‐cost/benefit analyses do not cope appropriately with the current lack of scientific understanding and the complexity of ecosystems that will become GEV recipients, and fail to take into account the deeper ethical groundings that shape the scientific and public opinions. To avoid serious, unintended ecological effects of GEVs, it may be necessary to elaborate the ethical basis for protecting health and the environment. The Precautionary Principle (PP) may provide a basis for adequate consideration of ecological and ethical issues of vital importance to protection of health and environment from unforeseen adverse effects of poxvirus‐vectored vaccines. To operationalise the PP, we suggest that there is a need to identify and systematise lack of scientific understanding, and to acknowledge uncertainty by initiating research with a broad focus involving interdisciplinary research. In this paper we present three main issues related to the employment of the PP: i) identification of scientific uncertainty and its ethical significance in risk assessment and risk management processes, ii) the need for broad risk assessment as a response to scientific uncertainty, and iii) the need for transparency and public involvement to enhance the debate about normative standards concerning acceptability of benefits, risks and uncertainty with regard to GEV use and release.     

Diversification of infrastructure projects for emergent and unknown non‐systematic risks

Allocating resources to competing large‐scale infrastructure projects involves multiple objectives. Traditional decision‐aiding methodologies focus on the trade‐offs among performance and resource objectives. Existing methodologies may fail to account for unknown and emergent risks that are typical of large‐scale infrastructure investment allocation problems. In modern portfolio theory, it is well known that a diversified portfolio can be very effective to reduce non‐systematic risks. The approach of diversification is equally important in choosing robust portfolios of infrastructure projects that may be subject to emergent and unknown risks. In this paper, we demonstrate a methodology to analyze and compare the diversification of portfolios of large‐scale infrastructure projects. We classify and explore several metrics of diversification and integrate them with risk and other performance objectives in a multiobjective approach. We test the new metrics and the methodology in a case study of hundreds of millions of dollars of infrastructure investments. The results suggest that the solutions that consider diversification are more robust to emergent risks, thus, identifying an opportunity to incorporate diversification‐based optimization methodologies to support a variety of problems involving large‐scale infrastructure investments.     

Individual differences in a switch from risk‐averse preferences for gains to risk‐seeking preferences for losses: can personality variables predict the risk preferences?

Individual differences on a framing problem and a reflection problem were examined in light of the Myers–Briggs Type Indicator. The predictions on information processing style, derived from Jungian personality type theory, were tested for the much‐discussed framing effect in the Asian Disease Problem and for the reflection effect on which the framing effect presumably depends. As anticipated, the results revealed that business students with higher iNtuition/Extraversion scores and lower Judging score were more likely to be consistently risk‐seeking. Conversely, those with higher Sensing/Judging scores were more likely to be consistently risk‐averse. Both framing and reflection effects were displayed by those with higher Sensing/Judging scores. However, the second expected result was not supported. Rather, a so‐called ‘gray hair/clouds’ effect (effect name inspired by Medin and Shoben's research in 1988), questioning the validity of risk propensity, was observed and analyzed. The somewhat surprising results and their theoretical and practical implications are discussed.     

Scientist and public responses to BSE‐related risk: A comparative study

Social studies of risk repeatedly have found substantial divergences in the way that experts/scientists and members of the general public appraise risks associated with health and environmental hazards. However, empirical evidence for these differences remains controversial. A recent review of literature suggests in particular that divergences between experts and lay people may potentially result from confounding socio‐demographic factors. The purpose of the present article is to investigate and to compare how medical scientists and members of the general population reacted to BSE (“mad cow disease”) in France. A sample of 401 scientists belonging to the French Institute of Health and Medical Research (INSERM) and a representative sample of 902 French citizens were asked about their cognitive, affective and behavioural responses to BSE. Results show that non‐scientists tended to express much more concern about BSE‐related risk than scientists, even when socio‐demographic variables were controlled. However, (1) no significant differences were found between these two groups concerning subjective epidemiological predictions, and (2) scientists manifested greater avoidance of beef or beef by‐products avoidance following the BSE epidemic than lay respondents did. The implications of these paradoxical results are discussed.     

A meta‐level analysis of major trends in environmental health risk governance

Internationally but also within countries, large differences exist regarding how environmental health risks (EHRs) are governed. Despite these differences, at a meta‐level some general trends can be discerned that may point to a convergence of EHR governance regimes. One, EHR governance regimes are increasingly taking into account cost‐benefit considerations, sectoral goals outside the health risk domain, public concerns and stakeholder interests in early stages of decision‐making. Two, EHR objectives are increasingly integrated in other, sectoral policies such as land use planning. Three, an increased differentiation of EHR standards is observed (partly as a consequence of the former characteristic). Still little systematic empirical research has been conducted on the dynamics in EHR governance regimes and their causes, on what EHR governance regimes have produced in terms of (perceived) risk reduction and on how these results can be explained. This paper proposes a systematic framework for analysing, explaining and evaluating shifts in EHR governance regimes. The framework in turn is applied to examine and understand the shift towards more integrated and differentiated EHR governance regimes.     

Evaluating an analytic–deliberative risk‐ranking process in a Chinese context

In previous research, a deliberative process for integrating stakeholder perspectives in the ranking of risks was introduced and empirically tested with lay groups composed predominantly of Americans. In this paper, we explore the viability of this process with lay groups of Chinese, because previous research has shown that Americans and Chinese differ substantially along many dimensions of cognition and social organization relevant to decision‐making. Using 10 environmental hazards based on current Chinese environmental regulatory programs as the risk domain, five groups of 8–9 participants ranked hazards using both holistic and multi‐attribute approaches. Results show that (1) risk rankings from the holistic and multi‐attribute approaches are consistent, (2) participants indicate that they are satisfied with the procedures and resulting rankings, and (3) agreement between participants increases over the course of the ranking exercise. Results for Chinese participants were compared with previously reported results for Americans to look for cultural effects involving deference to technical expertise and quantitative analysis, and skepticism toward public participation in policy‐making. Although there were some hints of cultural differences, neither difference significantly affected measures of the method’s validity or replicability. Because this process offers a scientifically sound and measured approach to stakeholder involvement in risk management, it may be attractive to Chinese leaders as they respond to growing demand for public participation in the policy‐making process. Whether Chinese citizens would consider the process described here to be satisfactory in a real policy context remains to be tested.     

Comparative optimism and risky road traffic behaviors among high‐risk sports practitioners

This study examines the relationship between participation in risky sports, comparative optimism (CO), and risky road traffic behaviors among a sample of adult men. We surveyed high‐risk (n = 313) and low‐risk (n = 53) sports practitioners, and non‐sportsmen (n = 89), assessing their CO, as well as their self‐reported risky behaviors and their accident experiences while driving a car. Results show that high‐risk sports practitioners expressed CO regarding the quality of their reflexes while driving and their vulnerability to traffic accidents. High‐risk sportsmen reported more risky behaviors while driving a car than the members of the other groups, and some of them, namely BASE‐jumpers, have experienced more traffic accidents. High‐risk sportsmen’s risky behaviors and accident experiences did not prevent them from expressing CO regarding their vulnerability to road accidents. Results are discussed, as well as putative psychological mechanisms underlying high‐risk sport practitioners’ CO and risky behaviors while driving.
