Adoption of Individual Flood Damage Mitigation Measures in New York City: An Extension of Protection Motivation Theory

This study offers insights into factors of influence on the implementation of flood damage mitigation measures by more than 1,000 homeowners who live in flood‐prone areas in New York City. Our theoretical basis for explaining flood preparedness decisions is protection motivation theory, which we extend using a variety of other variables that can have an important influence on individual decision making under risk, such as risk attitudes, time preferences, social norms, trust, and local flood risk management policies. Our results in relation to our main hypothesis are as follows. Individuals who live in high flood risk zones take more flood‐proofing measures in their home than individuals in low‐risk zones, which suggests the former group has a high threat appraisal. With regard to coping appraisal variables, we find that a high response efficacy and a high self‐efficacy play an important role in taking flood damage mitigation measures, while perceived response cost does not. In addition, a variety of behavioral characteristics influence individual decisions to flood‐proof homes, such as risk attitudes, time preferences, and private values of being well prepared for flooding. Investments in elevating one's home are mainly influenced by building code regulations and are negatively related with expectations of receiving federal disaster relief. We discuss a variety of policy recommendations to improve individual flood preparedness decisions, including incentives for risk reduction through flood insurance, and communication campaigns focused on coping appraisals and informing people about flood risk they face over long time horizons.     

Firth adjustment for Weibull current-status survival analysis

Abstract

Analysis of right-censored data is problematic due to infinite maximum likelihood estimates (MLE) and potentially biased estimates, especially for small numbers of events. Analyzing current-status data is especially troublesome because of the extreme loss of precision due to large failure intervals. We extend Firth’s method for regular parametric problems to current-status modeling with the Weibull distribution. Firth advocated a bias reduction method for MLE by systematically correcting the score equation. An advantage is that it is still applicable when the MLE does not exist. We present simulation studies and two illustrative analyses involving RFM mice lung tumor data.     

The Emergence of Career Development Facilitators

This article describes the collaborative efforts of the National Career Development Association, National Occupational Information Coordinating Committee, and Career Development Training Institute at Oakland University, which resulted in the emergence and recognition of the important role of career development facilitators (CDFs). The development of the CDF competencies, curriculum, and certification is summarized, and examples of counselor‐facilitator collaboration are provided.     

Statistical review by research ethics committees

This paper discusses some of the issues surrounding statistical review by research ethics committees (RECs). A survey of local RECs in 1997 revealed that only 27/184 (15%) included a statistician member at that time, although 70/175 (40%) recognized the need for such. The role of the statistician member is considered and the paper includes a summary of a meeting of the Royal Statistical Society to discuss statistical issues that frequently arise in the review of REC applications. A list of minimum qualifications which RECs should expect from anyone claiming to be a statistician would be useful, together with a list of statisticians who are well qualified and willing to serve on RECs, and a list of training courses for REC members covering the appropriate statistical issues.     

The Complementary Roles of Mitigation and Insurance in Managing Catastrophic Risks

This paper examines the impact that insurance coupled with specific risk mitigation measures (RMMs) could have on reducing losses from hurricanes and earthquakes as well as improving the solvency position of insurers who provide coverage against these hazards. We first explore why relatively few individuals adopt cost-effective RMMs by reporting on the results of empirical studies and controlled laboratory studies. We then investigate the impact that an RMM has on both the expected losses and those from a worst case scenario in two model cities—Oakland (an earthquake-prone area) and Miami/Dade County (a hurricane-prone area) which were constructed respectively with the assistance of two modeling firms. The paper then explores three programs for forging a meaningful public-private sector partnership: well-enforced building codes, insurance premium reductions linked with long-term loans, and lower deductibles on insurance policies tied to mitigation. We conclude by briefly examining four issues for future research on linking mitigation with insurance.     

Devil in the Details: A Critical Review of “Theoretical Loss”

In their review of Internet gambling studies, Auer and Griffiths (J Gambl Stud 30(4), 879–887, 2014) question the validity of using bet size as an indicator of gambling intensity. Instead, in that review and in a response (Auer and Griffiths, J Gambl Stud 31(3), 921–931, 2015) to a previous comment (Braverman et al., J Gambl Stud 31(2), 359–366, 2015), Auer and Griffiths suggested using “theoretical loss” as a preferable measure of gambling intensity. This comment extends and advances the discussion about measures of gambling intensity. In this paper, we describe previously identified problems that Auer and Griffiths need to address to sustain theoretical loss as a viable measure of gambling intensity and add details to the discussion that demonstrate difficulties associated with the use of theoretical loss with certain gambling games.     

Students' Experiences of University and an Australian Social Work Program: Coming,Going, Staying

Student engagement, retention, and professional commitment is strongly influenced during the early stages of the university experience. However, a number of factors can undermine engagement, which has implications for the individual, the professional workforce, and university funding and reputation. This paper reports on cooperative inquiry research that explored the beginning experiences of 17 social work students from one regional Australian university. In-depth, qualitative data were collected during six discussions that focused on understanding the experiences that influenced university retention, enjoyment, and success. Data analysis revealed three primary themes: (i) purpose and timing, (ii) balancing commitments, and (iii) a sense of belonging. Findings suggested that students often struggled to balance life, work, and family commitments, while appreciating university processes that reduced stressors and contributed to a sense of belonging.     

Australian Workers’ Narratives about Emergency Relief and Employment Service Clients: Complex Issues,Simple Solutions

This paper illuminates two under-investigated, and often intersecting, frontline services accessed by unemployed people. It reports on the narratives of 32 Australian service providers working in emergency relief or employment services during 2012, including perceptions of clients’ presenting issues and problems, and rationale for intervention. Workers tended to use reductionist and individualistic terms to describe complex client issues suggesting self-motivation and personal responsibility were key to gaining employment or alleviating poverty. Clients were often viewed as having the power to change their circumstances, while workers appeared unaware of their positional power and drew from dominant conservative discourse about welfarism and unemployment to fortify their compliance requirements. The findings are discussed in relation to service delivery and reform.
