A multi-attribute approach to assess homeland security risk

The United States Department of Homeland Security manages a wide spectrum of risks involving crime, terrorism, accidents, and natural disasters. This paper supports disaster management by identifying which attributes should be used to describe risks comprehensively and assessing the need to incorporate such multiattribute information into risk management processes. Attributes for describing homeland security risks were selected through a literature review. These attributes were then used in a risk assessment of homeland security hazards that informed risk ranking sessions conducted with members of the general public. The results taken together support the use of a range of attributes and perspectives. While aspects of life/health and economic damage were considered most important by both experts and the lay public, other attributes were of widespread importance, including attributes related to dread and uncertainty. These results demonstrate how to present risks in a deliberative risk management process and the importance of doing so using a complete set of attributes to describe the risks.     

Public perception of scientific uncertainty in relation to food hazards

The research reported here aims to understand how people react to statements expressing risk uncertainty information in the context of a commonly experienced potential hazard, food related risks. Public perception of seriousness of risk for themselves, and for other people was examined for different types of uncertainty, for each of five different food hazards. The results indicated that participants responded to the different types of uncertainty in a uniform way, suggesting that perception of risk associated with uncertainty is not affected by the 'type' of uncertainty. The results further indicated that the seriousness of risk, in the presence of statements of uncertainty, was perceived to be greater for pesticides and genetic modification compared to BSE, high fat diets and Salmonella . It was argued that this could be due to the perceptions of low personal control, and high societal responsibility to protect people and societal control over exposure to the potential risks of pesticides and genetic modification. Under circumstances where people feel they have little personal control over their exposure to a particular hazard, and those social institutions that are perceived to be in control of protecting the public indicate that there is uncertainty associated with risk estimates, the hazard may appear to be 'out of control', which is associated with a perception of serious risk.     

Schöne Aussicht auf den Fluss? Wahrnehmung von Risiken aus Naturkatastrophen

Impacts of natural disasters have increased worldwide during the last decades. Facing the growing losses from natural hazards also in Germany, the question emerges how persons in likely affected areas perceive risks from natural hazards such as windstorm, flood, and earthquake. The everyday, ?intuitive“ perception of risks is basic for the individual, subjective assessment of natural risks. Consequently, perception and evaluation of risk is basic for behaviour in dangerous situations. It is also fundamental for decisions concerning preventive protective measurements. To be able to develop effective information and communication strategies and politics about natural risks, the perception and evaluation of these risks and influencing factors should be known. Therefore, the purpose of the study presented in this paper is to focus on the perception of storms, floods, and earthquakes and to study factors that influence risk perception. To study risk perception, a mail survey was conducted in summer 2001 in six regions of Germany which had been affected by windstorm, flood and / or earthquake within the last 30 years. Köln-Rodenkirchen, Passau, Karlsruhe, Neustadt/Donau, Albstadt and Rosenheim were selected as survey areas. In total, 450 persons responded the questionnaire. In the study a mixture of approaches to risk perception was applied, among them the psychometric paradigm. The project was conducted at the Institute for Insurance, Universität Karlsruhe (TH) and additionally funded by the Stiftung Umwelt und Schadenvorsorge der SV Versicherungen. The results show that storm, flood, and earthquake are rated heteroge-neously regarding their general dangerousness, several risk characteristics and attributions of causes. Personal characteristics, such as age, education level, and the experience of damage seem to play a role for the general risk rating. In addition, the risk perception of homeowners and tenants differs.     

Managing risk through the veil of ignorance

Background. We view overconfidence within risk management as a problem likely to manifest within philosophical preferences for anticipationism over resilienism, and in assumptions that risks are objectively real external powers or potentialities rather than subjective knowledge propositions. Methods. We argue that the realist tradition within Italian social theory, first crystallised by Niccolò Machiavelli and later elaborated by the sociologist Vilfredo Pareto, offers valuable lessons for corporate risk management praxis by demanding that we map out the complex relations between the risk subjectivities of risk managers, and their objective risk environments, from a standpoint of psychological and sociological realism which stresses the risk ignorance of practitioners. We caution that risk management efforts to improve risk subjectivities to achieve perfect veridicality to objective risk environments might often amount to a wishful bildungsroman of epistemological growth, reflecting the common aspirations of risk managers to demonstrate professional competence. We suggest that the profession should control this overconfidence problem by stressing the corrigibility of risk subjectivities with reference to sociological understandings that reflect on the widespread risk ignorance that can persist and even intensify where risk management effort is made. Results. Following the macrosociological framework sketched by Pareto, we show how two common ‘modes of uncertainty’ can be scrutinised for their adaptive fitness to two common types of risk environment. Conclusions. It can be helpful to think sociologically of organisations as engaging with some highly significant strategic risks blindly through a veil of ignorance.     

Performativity and the politics of identity: Putting Butler to work

Judith Butler occupies centre-stage in debates about gender identities. Butler's key concept is performativity: the ways in which gender identity is embodied and enacted, rather than a more or less adequate reflection of some underlying bodily reality. Butler draws on Foucault in several respects, not least her stress on the physicality of individual and social life, and her concern to understand identity as a social process. Identity is always provisional rather complete, a deeply ambiguous and unstable moment. Performativity is not reducible to performance and the degree of choice involved in identity construction both makes it appear more ‘natural’ for the individual and also open to reinterpretation. This is where Butler finds political hope. Foucauldian research on contemporary work identities has largely ignored Butler. Corporate, professional and occupational identities are too often portrayed as simply imposed on individuals in ways that leave little scope for ambiguity or negotiation. Butler's notion of performativity provides a way of understanding the ambiguities and paradoxes of contemporary identities at work.     

Sense-making of risk and role-taking emotions: how young Swedes construe road traffic risk

The aim of this study is to improve our understanding of how young people make sense of traffic risk. The study also aims to contribute to current theory by refining the concept of ‘sense-making of risk’. The focus is to explore, empirically as well as theoretically, how role-taking emotions can contribute to this particular area of research. In order to chart both the sense-making of social interaction and the respondents’ subjective sense of traffic risk, the present study used both in-depth interviews and focus group interviews: the in-depth interviews comprised a total of 11 interviews with as many interviewees, while a total of 36 people were included in the eight focus group interviews. All interviewees were Swedish residents aged between 16 and 20. It is found that by adopting the perspective afforded by theory of emotion, it is possible to deepen our knowledge of individual sense-making of risk. Both primary emotions and role-taking emotions seem to be central to how young Swedes form their understanding of traffic risk. A focus on role-taking emotions reveals the value of indirect social interaction for the individual’s sense-making of risk in general, and adds to our knowledge of the individual’s sense-making of traffic risk in particular.     

Complexity,uncertainty and future risks

Roger Kasperson’s paper prompts us to reflect on whether traditional risk communication tools and approaches might be inadequate for many of the tasks now emerging. One can point to the increasingly complex nature of some technological and environmental hazards; the need to scrutinise emerging technologies upstream of significant applications; and fundamental changes to risk identities within society. Perhaps, we now genuinely face a risk society, exemplified by the dysfunction of global financial systems, extreme inequalities and encroaching environmental threats, alongside the unwinding of traditional social identities? Strategic capacity to address many of these fundamental risk challenges is lacking.     

The meaning of risk-taking – key concepts and dimensions

Dealing with and taking risks are central issues of current societies which had been characterised by heightened debates and conflicts about risk (Beck, Giddens). Even though there is good knowledge available, policies and strategies to reduce people’s risk-taking are often less successful than expected. Experts are puzzled about common people not following good advice presuming people’s lack of understanding. While this might be true in many cases a growing body of research shows, rather than being merely ignorant or misinformed, people often have good knowledge when taking risks. A growing body of research provides knowledge about the complexities, dynamics and contradictions of people’s risk-taking. However, there have been little attempts to systematise this body of knowledge. This article contributes to such an enterprise. It suggests distinguishing between different motives for risk-taking, different levels of control and a number of ways how reflexivity about risk is rooted in the social realm. It also explores how risk-taking is part of developing and protecting a valued identity. The article concludes, across different domains there is good evidence for how structural and cultural forces combine and shape risk-taking while people take risks to develop a valued identity and to protect it. Advancing expert’s understanding of risk-taking and change people’s risk-taking require considering and approaching the larger social contexts and individual risk practices in everyday life.     

Review of industrial safety management by international agreements and institutions

A review of the management of industrial safety on the basis of international agreements and institutions is presented. Focus is given to risks related to the chemical process industry. First, the key technical elements of the process to assess and manage industrial risks are described together with the related key legislative principles. Various techniques exist for the assessment of risk of industrial operations, and for the assessment of hazards to the environment and mankind. These techniques share common areas, e.g., with regard to data collection and interpretation, that offer the possibility of synergetic approaches via international agreements and institutions. In addition to technical risk assessment, cultural factors will need to be taken into account when addressing the topic of acceptable risk in any given social context. Next, various examples of current risk management frameworks in a multi‐ and bilateral context are given. Eventually, as a concrete example of an industrial risk management framework, the European Union's legislation to control major accident hazards, the Seveso II Directive, is discussed. An outlook on future actions concludes the paper.     

The consequences of perceived risk and objective knowledge for consumers’ investment behavior

Knowledge and risks have a focal role in consumer behavior. However, studies on consumers’ perceive risks in decision situations and the influence of objective knowledge and experience on risk perceptions, consumers’ attitudes and behavioral intentions are scarce. This paper introduces and tests a novel conceptual model that shows how consumers’ objective financial knowledge and investing experience affect their future investment intentions mediated by perceived risks, and attitudes toward investing. The data were analyzed using structural equation modeling. The proposed model fits the data and accounts for attitudes and intentions to investing. This study advances knowledge by directly measuring the behavior-related objective knowledge and experience. We also suggest new insights into the risk concept by showing that consumers perceive five types of risk in investing context and objective financial knowledge and investment experience has varying effects on different risks types, attitudes and intentions. The results also show significant gender differences.     

Visualizing risk: using participatory photography to explore individuals’ sense-making of risk

Although the field of risk research is increasingly alert to new theoretical and empirical perspectives, it is still the case that few studies take a visual approach, despite its obvious worth in capturing people’s experiences of everyday life. This paper considers how a visual approach can be used to deepen our knowledge of sense-making of risk, particularly young people’s views on risk. It presents empirical findings from a study that uses participatory photography to capture what individuals define as serious risks in everyday life and how these risks are expressed (722 participants in Sweden, aged 5–33, mostly children or adolescents). The conclusion is that focusing on stories embedded in images independently contributes new knowledge about how the individual makes sense of risk in everyday life, and especially that visual methods of data collection and analysis illuminate how individual sense-making of risk is intertwined with other aspects of meaning-making in everyday life. In other words, it is time for a visual turn in risk research.     

Convex risk measures for the aggregation of multiple information sources and applications in insurance

We propose a novel class of convex risk measures, based on the concept of the Fréchet mean, designed in order to handle uncertainty which arises from multiple information sources regarding the risk factors of interest. The proposed risk measures robustly characterize the exposure of the firm, by filtering out appropriately the partial information available in individual sources into an aggregate model for the risk factors of interest. Importantly, the proposed risks can be expressed in closed analytic forms allowing for interesting qualitative interpretations as well as comparative statics and thus facilitate their use in the everyday risk management process of the insurance firms. The potential use of the proposed risk measures in insurance is illustrated by two concrete applications, capital risk allocation and premia calculation under uncertainty.     

Precautionary principle and discursive strategies: classifying and managing risks

The paper covers an integral risk concept consisting of a criteria-based risk evaluation, a novel proposal for risk classification and corresponding risk management strategies aimed at an analytic-deliberative approach in risk regulation. For this purpose, technical and scientific as well as social scientific concepts were integrated into a single conceptual framework. Eight criteria were selected for evaluating risks: probability of occurrence, extent of damage, incertitude, ubiquity, persistency, reversibility, delay effect and potential of mobilization. With respect to these criteria, six risk classes were formed in which risks may exceed thresholds determined by deliberative action. Effective and practicable management strategies were deduced for each risk class. The characterization and classification of risks provide a knowledge base for designing risk policies and class-specific management strategies. Three major management categories were identified: risk-based, precautionary and discursive strategies. In deliberative processes actors need to agree on norms and procedures to manage risks. If the results reflect the agreement of previous discourse procedures, political decisions become more legitimate. Because the risk evaluation, risk classification and management strategies are based on the concept of analytic-deliberative processes, the essential requirements for an effective and democratic risk policy are met.     

Perception of technological risk: insights from research and lessons for risk communication and management

Technology has become a familiar companion in all areas of life. Production consumption, administration, education, communication, and leisure activities are all shaped by the use of technologies. However, people often associate with the term ‘technology’ attributes, such as catastrophic and potentially dangerous, and tend to take the benefits of technological products for granted. This asymmetry in risk–benefit perception is one of the main reasons why many consumers are concerned about ‘hidden’ risks of technologies and why they demand stringent regulatory actions when they feel unduly exposed to potential emissions or waste products associated with the lifecycle of technologies. This situation is often aggravated by social amplification processes, by which even small risks receive high media attention and are blown out of proportion in the public arena. At the same time, however, one needs to acknowledge that many technologies have the potential to harm the human health and the environment. The purpose of this article is to review our knowledge about risk perception with respect to technologies, in particular emerging technologies, and to suggest possible strategies to use this knowledge for improving our risk management practice. Technological risk perception is defined in this article as the processing of physical signals and/or information about a potentially harmful impact of using technology and the formation of a judgment about seriousness, likelihood, and acceptability of the respective technology. Based on the review of psychological, social, and cultural factors that shape individual and social risk perceptions, we have attempted to develop a structured framework that provides an integrative and systematic perspective on technological risk perception and that may assist risk management and regulation in taking perceptions into account.     

Differences in the strengths of evidence matters in risk–risk trade-offs

Making decisions between alternatives are challenging when there is weak or unreliable knowledge about the risks and benefits of the alternatives. This requires a trade-off between risks (and benefits). Here, we comment on a recent paper on risk–risk trade-offs and highlight the difficulties of making such trade-offs when the available evidence is of different strength. One current example of a risk–risk trade-off under weak evidence is the restriction and reevaluation of the risks of neonicotinoid insecticides to bees conducted by the European Food Safety Authority (EFSA). We argue that a risk–risk trade-off is essential in this context. Although considerable research efforts have been focused at determining the risks of neonicotinoids to bees, the evidence base is still limited. However, focus on strengthening evidence on impacts of one substance may lead policy-makers and public to believe that its substitutes are less harmful, when in fact evidence is weak on the impacts of these substitutes as well. We argue that a broader management of uncertainty is needed and that the difference in uncertainty underlying evidence of risk for different alternatives needs to be communicated to policy-makers. We suggest that this can be done, for example, using measures of uncertainty, which take into account strength in evidence, and combine these with principles to guide decision-making.     

Social vulnerability indexes as planning tools: beyond the preparedness paradigm

This article draws from the experience of the ongoing drafting of the Regional Plan of the Centre Region of Portugal, and the empirical application of the Social Vulnerability Index proposed by Susan Cutter. It consists in the construction of an index of social vulnerability to natural and technological hazards and to social risks for all the municipalities of the region. Methodologically, it extends the vulnerability analysis to technological hazards and social risks, as a more encompassing view is necessary for the elaboration of prevention and civil protection policies. The results confirm the interactive nature of social vulnerability, and they also reflect the diffuse urbanisation and industrialisation patterns that characterise Portugal. The scattered nature of social facilities and security and health infrastructures pose specific challenges to planners concerning risk prevention and mitigation, and the elaboration of effective risk communication strategies adapted to specific hazards and risks in the studied municipalities. The article concludes with some reflections on the need to revise established paradigms of disaster analysis and emphasise the importance of pre‐event planning and the social cartography of vulnerable populations for effective prevention and security policies that take into account social inequalities and citizenship rights.     

Influences of individual-level characteristics on risk perceptions to various categories of environmental health and safety risks

Over the last five decades, social science researchers have examined how the public perceives the risks associated with a variety of environmental health and safety (EHS) hazards. The body of literature that has been emerged diverse both in the methodology employed to collect and analyze data and in the subject of study. The findings have confirmed that risk perceptions vary between groups of individuals as well as between categories of EHS risks. However, the extant literature on EHS risk perceptions has failed to provide empirical insights into how risk perceptions can be best explained according to the interplay of both (1) the category of EHS hazard appraised and (2) the prominent individual-level characteristics that best explain observed risk perception differences. This study addresses this deficiency in the literature by providing insights into the individual and cumulative roles that various individual-level variables play in characterizing risk perceptions to various categories of EHS risks including ‘agentic risks’ like street drug use and cigarette smoking, ‘emerging technological risks’ like nanoparticles and cloning, and ‘manufacturing risks’ like air and chemical pollution. Our data are drawn from the 2009 Citizens, Science, and Emerging Technologies national study of United States households that investigated public perceptions of EHS risks, traditional and emerging media use, and various individual characteristics like personal demographics, socioeconomic factors, and perceptual filters. The findings show that some categories of EHS risks like those associated with emerging technologies may be more easily predicted than other categories of risks and that individual-level characteristics vary in their explanative power between risk categories even among a single sample of respondents.     

Local facility hazard risk controversy and non-local hazard risk perception

Facility siting disputes are as much about the socio-politics in a place as they are about the risks posed by the facility; yet not much is known about how localized controversy about one hazard effects the perception of other, non-local, hazard risks. Our exploratory study tests the idea that a local facility risk controversy (landfill expansion) is tied to an overall sensitivity to risks from a wider range of potentially hazardous facilities. We use logistic regression models of questionnaire survey responses from 205 residents living near two landfills that were recently expanded or proposed to be expanded. Psychometric risk variables, cultural theory of risk variables, and sociodemographic variables are used as controls to see if risk-in-place/context variables related to threat and governance (e.g. fairness and fiduciary equity) predict not only risk from the landfill but also risk from three other potentially hazardous facilities (incinerator, chemical, and nuclear). The risk-in-place/context variables are predictive across all hazards but there is little consistency in the mix of predictors across models. The results suggest that facility controversy is linked to how residents view risks from non-local facility hazards and that this effect varies by place. This points to the need for more research in this area, and is suggestive that risk-hazard controversy may foster localized risk-averse places or wider risk-averse communities.     

Risk cultures and dominant approaches towards disasters in seven European countries

This paper builds upon the risk culture concept started with Mary Douglas’ and Aaron Wildavsky’s seminal work on risk and culture. Based upon the empirical results of a qualitative sociological study on sociocultural factors affecting risk perception and crisis communication in seven European countries, a theoretical model, illustrating how differences in disasters framing imply diverse approaches to risk and disaster management, is suggested. According to this framework, culturally bounded assumptions and conventions strongly influence how communities make sense of risks and hazards and how these communities consider some ways of dealing with disasters more appropriate than others. The framework suggested in this article distinguishes between risk cultures of a given society, which do not necessarily respond to nation states. In order to explain differences in how cultures deal with risks and disasters, and to define the main features of our typology, three main interrelated dimensions have been selected: disaster framing, trust in authorities and blaming. By analyzing differences and similarities in how people perceive and interpret disasters, as well as to whom the responsibility for risk prevention and crisis management is attributed, in seven European countries, three specific ideal types of risk cultures emerged: state-oriented risk culture, individual-oriented risk culture and fatalistic risk culture. Implications for crisis management and communication in case of a disaster will be addressed for each of these risk cultures.     

极端气候对商业银行风险承担的影响——来自中国地方性商业银行的经验证据

深化对气候相关金融风险的认识,对于促进绿色低碳发展,防范系统性金融风险具有重要意义。本文以2004—2018年期间281家中国地方性商业银行为样本,实证检验了极端气候对银行风险承担的影响及其机制。研究发现,极端强降水气候显著提升了银行风险承担,极端高温和极端低温气候对银行风险承担不存在明显影响。极端强降水主要通过给银行信贷主体带来经济损失,影响违约概率和银行信贷资产质量,进而影响银行风险承担水平;提高灾前的保险保障水平、强化碳减排机制以及确保银行资本的充足性均有利于弱化极端气候对银行风险承担的影响;相较于以地级和省会城市工商业和居民为主要服务对象的地方性商业银行,极端强降水对以“三农”为主要服务对象的县域地方性商业银行风险承担的影响更大。因此,提升商业银行应对极端气候风险意识,提高气候灾害保险保障水平,强化碳减排机制和银行资本充足管理,均有利于降低极端气候对银行风险的影响。
