Perception and Communication of Flood Risks: A Systematic Review of Empirical Research

Flood hazards are the most common and destructive of all natural disasters. For decades, experts have been examining how flood losses can be mitigated. Just as in other risk domains, the study of risk perception and risk communication has gained increasing interest in flood risk management. Because of this research growth, a review of the state of the art in this domain is believed necessary. The review comprises 57 empirically based peer‐reviewed articles on flood risk perception and communication from the Web of Science and Scopus databases. The characteristics of these articles are listed in a comprehensive table, presenting research design, research variables, and key findings. From this review, it follows that the majority of studies are of exploratory nature and have not applied any of the theoretical frameworks that are available in social science research. Consequently, a methodological standardization in measuring and analyzing people's flood risk perceptions and their adaptive behaviors is hardly present. This heterogeneity leads to difficulties in comparing results among studies. It is also shown that theoretical and empirical studies on flood risk communication are nearly nonexistent. The article concludes with a summary on methodological issues in the fields of flood‐risk perception and flood‐risk communication and proposes an agenda for future research.     

Improving Flood Risk Communication by Focusing on Prevention‐Focused Motivation

This article proposes an approach to flood risk communication that gives particular emphasis to the distinction between prevention and promotion motivation. According to E. Tory Higgins, the promotion system and the prevention system are assumed to coexist in every person, but one or the other may be temporarily or chronically more accessible. These insights have far‐reaching implications for our understanding of people's reasoning about risks. Flood risk communication framed in terms of prevention involves the notions of chance and harm, woven into a story about particular events that necessitate decisions to be more careful about safety issues and protect one's family and oneself from danger. The article describes how the insights worked out in practice, using a flood risk communication experiment among a sample from the general population in a highly populated river delta of the Netherlands. It had a posttest‐only control group design (n = 2,302). The results showed that risk communication had a large effect on the participants’ responses and that this effect was higher among chronic prevention‐focused people than among others. Any information that increased the fit between a prevention‐framed message and a person's chronic prevention motivation produced stronger situationally induced, prevention‐focused responses. This may significantly improve communication about risks. In contrast, the notion of water city projects, featuring waterside living, had more appeal to promotion‐focused people.     

Emotions,Trust, and Perceived Risk: Affective and Cognitive Routes to Flood Preparedness Behavior

Despite the prognoses of the effects of global warming (e.g., rising sea levels, increasing river discharges), few international studies have addressed how flood preparedness should be stimulated among private citizens. This article aims to predict Dutch citizens’ flood preparedness intentions by testing a path model, including previous flood hazard experiences, trust in public flood protection, and flood risk perceptions (both affective and cognitive components). Data were collected through questionnaire surveys in two coastal communities (n= 169, n= 244) and in one river area community (n= 658). Causal relations were tested by means of structural equation modeling (SEM). Overall, the results indicate that both cognitive and affective mechanisms influence citizens’ preparedness intentions. First, a higher level of trust reduces citizens’ perceptions of flood likelihood, which in turn hampers their flood preparedness intentions (cognitive route). Second, trust also lessens the amount of dread evoked by flood risk, which in turn impedes flood preparedness intentions (affective route). Moreover, the affective route showed that levels of dread were especially influenced by citizens’ negative and positive emotions related to their previous flood hazard experiences. Negative emotions most often reflected fear and powerlessness, while positive emotions most frequently reflected feelings of solidarity. The results are consistent with the affect heuristic and the historical context of Dutch flood risk management. The great challenge for flood risk management is the accommodation of both cognitive and affective mechanisms in risk communications, especially when most people lack an emotional basis stemming from previous flood hazard events.     

Customer satisfaction: Cost driver or value driver? Empirical evidence from the financial services industry

We investigate the relation between customer satisfaction, customer servicing costs, and customer value in a financial services firm. We find that customer satisfaction is positively associated with future customer servicing costs, as well as with customer value. The relation between customer satisfaction and customer value appears non-linear; higher customer satisfaction appears to have a higher return for the most profitable customer segments. Our findings indicate that customer satisfaction is a value driver; however, customer satisfaction is not cost-free and managers have to consider the costs, as well as the benefits, of increasing customer satisfaction.     

Older Parents Providing Child Care for Adult Children: Does It Pay Off?

This study examined whether past grandparental child care is related to present support from adult children. On the basis of social exchange theory, the authors expected that grandparental child care creates a debt that is repaid in the form of receiving support later in life. Using data from the Longitudinal Aging Study Amsterdam (N = 349 parents, N = 812 adult children), the authors found that grandparents who frequently provided child care for sons in the past more often received instrumental and emotional support from these sons approximately 13 years later than grandparents who less frequently provided child care. Investments in daughters did not pay off. Instrumental support other than child‐care provision did not predict receiving support from either sons or daughters, but emotional support did. These results support the notion of long‐term reciprocity in parent–child relationships, but its importance depends on the child's gender and the type of earlier investment.     

The rich and exacting role of the social worker in family foster care

This article is about the role of the professional social worker in a child placing agency. It emphasizes the worker's central role in coordinating or managing the various facets of family foster care.Many aspects of family foster care are discussed, with emphasis upon permanence and the tasks of the social worker with the respective participants. The article briefly examines these activities, such as working with the child, the birth parents and the foster parents, within the contexts of the primary mission which is to restore family relationships or to help the child to find and build new ones.Mr. Terpstra is employed by the U.S. Children's Bureau where he serves as a specialist in family foster care, child care insittutions and licensing of children's services.     

Weighted L1-estimates for the First-order Bifurcating Autoregressive Model

We developed robust estimators that minimize a weighted L₁ norm for the first-order bifurcating autoregressive model. When all of the weights are fixed, our estimate is an L₁ estimate that is robust against outlying points in the response space and more efficient than the least squares estimate for heavy-tailed error distributions. When the weights are random and depend on the points in the factor space, the weighted L₁ estimate is robust against outlying points in the factor space. Simulated and artificial examples are presented. The behavior of the proposed estimate is modeled through a Monte Carlo study.     

What's in a Frame? How Professionals Assess Clients in Dutch Work Reintegration Practice

With the increased attention on labour market participation, the field of work reintegration support has grown dramatically. In order to improve professionals' performance, standards and performance measures are introduced in this field. We question whether this will improve the quality of their work. Closer scrutiny needs to be paid to the inherently normative and structuring role of professional judging. We applied the concept of ‘frames of reference’ to the process of professional judgement in work reintegration. This concept helped us to understand how a work reintegration professional structures a client's story through implicit rules that escape formalization and control mechanisms. On the basis of 24 in‐depth interviews with diverse work reintegration professionals in the Netherlands, we distinguish five of these frames: a procedural, a work‐focused, a caring, a learning and a facilitating frame of reference. Furthermore, we show that professionals differ widely in the images they have of clients, leading to a large variety in judgement of, and interaction with, clients. Though differences between professionals are inherent to a complex and dynamic field as work reintegration, the current variety in professional‐client contact in work reintegration seems to depend too much on arbitrary professional preferences. Therefore, reflection on these differences, both among professionals and by policymakers, is needed in order to improve the professional practice of work reintegration service.     

A Nonparametric Test for the Ordered Alternative Based on Kendall's Correlation Coefficient
