Insurance for low-probability hazards: A bimodal response to unlikely events

Two insurance experiments using real-money consequences and multiple rounds to provide experience are described. In the first experiment, subjects bid for insurance to prevent a fixed loss of 4 at probabilities ranging from .01 to .9. Mean bids were near expected value except at the lowest probability of.01, for which a very bimodal distribution was observed (some subjects bid zero and others bid much more than expected value). A second experiment explored this bimodality at a probability of .01 with loss increased to4 at probabilities ranging from .01 to .9. Mean bids were near expected value except at the lowest probability of.01, for which a very bimodal distribution was observed (some subjects bid zero and others bid much more than expected value). A second experiment explored this bimodality at a probability of .01 with loss increased to 40. A similar bimodal distribution was obtained that persisted over 50 rounds of experience. These laboratory results are consistent with field evidence for low-probability hazards, for which people appear either to dismiss the risks or to worry too much about them.We would like to thank Alan Carlin, Ann Fisher, Risa Palm, and David Brookshire for their helpful comments on an earlier version of this article, and Rebecca Boyce, Julie Irwin, Glenn Russell, and Joy Smith for research assistance.

The Moral Economy of Intergenerational Redistribution in an Ageing Society: A Qualitative Analysis of Young Adults' Beliefs in the United States

In the USA, the largest generation, the Baby Boomers, is currently retiring and increasingly drawing from Old Age Social Security. In this context, young generations are said to be disadvantaged: they have to support a growing number of pensioners while expecting much lower pensions themselves. Drawing on 14 original semi‐structured interviews with young US citizens aged 20–36, this study analyzes the moral economy of intergenerational redistribution – defined as normative beliefs and justifications of a just distribution of contributions and benefits between generations. The qualitative content analysis resorts to the four constituent institutional principles of intergenerational redistribution: deservingness (being qualified to receive support), reciprocity (mutual support between generations), equity (relation between in‐ and outputs for one generation) and equality (corresponding conditions for different generations). The first main finding is that the young hold multiple normative beliefs in favour of intergenerational redistribution. The second main finding is that different normative beliefs and justifications can compensate for feelings of injustice attributable to the consequences of an ageing society. The qualitative findings' contributions to the field of study that is dominated by quantitative studies are concluded. Implications for public support for intergenerational redistribution in the ageing society of the USA and other countries are discussed.     

Critical Components in Implementing Evidence‐based Practice: A Multiple Case Study of Individual Placement and Support for People with Psychiatric Disabilities

When developing Community Mental Health Services to support people with psychiatric disabilities, European countries are advocating evidence ‐based practice (EBP ). Individual Placement and Support (IPS ) is an evidence ‐based model designed to support people in acquiring and maintaining competitive employment. Implementation science is a growing research field, with a focus on components that impact the process of implementing EBP programmes. In this multiple case study, we have followed three IPS demonstration sites for two years, in order to describe and analyze barriers and facilitators for implementation, according to constructs described in the Consolidated Framework for Implementation Research (Damschroder et al. 2009 ). The results highlight the importance of strategic networking, as well as the need for planning and preparations carried out before the start of an EBP programme, since deficiencies related to these constructs are difficult to compensate for.      

Suicide Prevention Training Program for Gatekeepers Working in Community Hospice Settings

Gatekeepers in community hospice settings encounter patients and caregivers struggling with suicidal thoughts. Limited guidance is available for training staff on the prevention of suicide in hospice care. This study evaluated one promising, evidence-based, suicide prevention program with a behavioral rehearsal practice session. A pre- and post-, one group design, was utilized to measure the training impact and educational needs of staff working in community hospice settings (N =39). Training increased awareness of the risk factors for suicide, as reported by nearly 80% of participants. Self-efficacy scores showed a statistically significant Increase, t(df = 35), ?9.59, p= .00 (two-tailed), from pretraining (n=36, M=2.21, SD= .65) to posttraining (n=36, M=3.03, SD=.56). Satisfaction and the need for additional devoted time for suicide prevention training were highly rated. Suicide prevention training programs can enhance self-efficacy, knowledge, and skills for gatekeepers working in community hospice settings.     

Networking Enforced – Comparing Social Services' Collaborative Rationales across Different Welfare Regimes

Collaboration and networking are ubiquitous, versatile features of social service provision in most Western countries. However, it is an open question whether networking means and entails the same across countries. Comparing regulatory frameworks in three jurisdictions representing distinctive ‘worlds of welfare services’ – Germany, Norway and Quebec – this article aims at eliciting the normative rationales that underpin and inform local service networks in child welfare and protection (CWP) systems. In Norway, where services are little diversified and largely insular, networking appears as a way of opening up for greater organizational plurality, within and beyond the public sector realm. In Germany in contrast, where services are highly pluralized and fragmented, networks are seen as an instrument for streamlining complexity. As for Quebec – an intermediate case in some respects – networking is envisioned as a catalyst for aligning two co‐existing service streams and mitigating the child protection–family support divide. Interestingly, in all three places, networking is now being enforced through similar highly formalized, top‐down regulatory provisions, even though the intended directions of change differ markedly. This has implications for CWP policy as well as research on networks at large.     

Re B‐S: a glass half full? An exploration of the implications of the Re B‐S judgment on practice in the family courts

The family courts in England and Wales are being significantly reformed in line with the coalition government's aim to speed up the process and increase the numbers of children being adopted from care. In September 2013, the Court of Appeal handed down a judgment, Re B‐S (Children) [2013] EWCA Civ 1146, that has wide‐ranging implications for professional practice and decision making in care proceedings. The judgment challenges the policy direction and provides guidance about what is required before courts can make orders separating children from their birth families, particularly in cases of non‐consensual adoption. In this paper, we outline the changes occurring in the family justice system, some key elements of Re B‐S, and examine the challenges for implementing practice consistent with the requirements of Re B‐S. It is argued that the standards set by Re B‐S are unlikely to be fully implemented without much further attention to the complexities posed by the policy and practice context of social work with children and their families involved in care proceedings.     

Coping and Post-traumatic Stress after Hurricanes Katrina and Rita: Racial Disparities in Social Work Student-Practitioners

ABSTRACT

Recent hurricanes have focused on lives and properties lost, however, additional mental health concerns may emerge in these post-disaster settings. Post-traumatic stress symptoms (PTSS) are particularly problematic for minorities due to pre-disaster disparities. Scholars must thus examine the antecedents of PTSS to support these and other vulnerable individuals and communities. This study examined racial disparities regarding active and avoidant coping, prayer, and subsequent relative contribution of each to PTSS following Hurricanes Katrina and Rita among social work student-practitioners. Using secondary data, results revealed that minority students (n = 233) used coping via prayer more often than their non-minority peers (n = 124; t = 7.18, p < .000; d = 0.76). Moderate, positive relationships emerged between avoidant coping and PTSS for both groups (r = .58–.63, p<.01), though prayer did not emerge as inversely related to PTSS as anticipated. Avoidant coping accounted for the largest variation in PTSS for both groups (β = .35–.51, p<.001). Sampling, survey methods, and PTSS measures limit generalizability and temper findings. Directions for future research include use of PTSS measures that account for severity and cultural context and examination of coping measure psychometrics. Practice implications include enhanced publicity regarding social services available to student-practitioners on college campuses and within the community.     

Modus Ponens and Modus Tollens for Conditional Probabilities,and Updating on Uncertain Evidence

There are narrowest bounds for P(h) when P(e)  =  y and P(h/e)  =  x, which bounds collapse to x as y goes to 1. A theorem for these bounds – Bounds for Probable Modus Ponens – entails a principle for updating on possibly uncertain evidence subject to these bounds that is a generalization of the principle for updating by conditioning on certain evidence. This way of updating on possibly uncertain evidence is appropriate when updating by ‘probability kinematics’ or ‘Jeffrey-conditioning’ is, and apparently in countless other cases as well. A more complicated theorem due to Karl Wagner – Bounds for Probable Modus Tollens – registers narrowest bounds for P(∼h) when P(∼e) =  y and P(e/h)  =  x. This theorem serves another principle for updating on possibly uncertain evidence that might be termed ‘contraditioning’, though it is for a way of updating that seems in practice to be frequently not appropriate. It is definitely not a way of putting down a theory – for example, a random-chance theory of the apparent fine-tuning for life of the parameters of standard physics – merely on the ground that the theory made extremely unlikely conditions of which we are now nearly certain. These theorems for bounds and updating are addressed to standard conditional probabilities defined as ratios of probabilities. Adaptations for Hosiasson-Lindenbaum ‘free-standing’ conditional probabilities are provided. The extended on-line version of this article (URL: ) includes appendices and expansions of several notes. Appendix A contains demonstrations and confirmations of elements of those adaptations. Appendix B discusses and elaborates analogues of modus ponens and modus tollens for probabilities and conditional probabilities found in Elliott Sober’s “Intelligent Design and Probability Reasoning.” Appendix C adds to observations made below regarding relations of Probability Kinematics and updating subject to Bounds for Probable Modus Ponens.      

Social assistance in Shanghai: Dynamics between social protection and informal employment

China's social assistance programme (dibao 低保) was introduced in Shanghai in 1993 and gradually extended to cover all urban areas by 1998. Due to massive economic restructuring, starting in the early 1990s, many urban dibao recipients were laid‐off, that is, state‐owned enterprise (SOE) employees. Shanghai was the epicentre of SOE reform, and the dibao system was primarily introduced to provide a safety net for laid‐off workers. In 2010, approximately 3 per cent of urban, permanent residents were on dibao, and 72 per cent of its recipients were working‐age adults. We conducted longitudinal qualitative interviews five times over 2 years with 40 dibao families that contained adults of working age in a Shanghai district. The current study demonstrates how they managed their employment, income and the dibao system. Findings suggested that, for various reasons, there was insufficient motivation for recipients to gain reemployment and leave dibao. Furthermore, local cadres, which were responsible for assessing and recommending dibao applicants to the district government, likely just assumed the incomes of adults with working capabilities.     

Complementary relations in the theory of preference

(1) This paper uses the following binary relations: > (is preferred to); ⩽ (is not preferred to); < (is less preferred than); ~ (is indifferent to). (2) Savage used primitive ⩾, postulated to be connected and transitive onA (the set of acts), to define the others: [x ~ y ⇔ (x ⩽ y and y ⩽ x)]; [y < x ⇔ notx ⩽ y]; [x > y ⇔ y < x]. Independently of the axioms, this definition implies that ⩽ and > are complementary relations onA: [x < y ⇔ notx > y]. (3) Pratt, Raiffa and Schlaifer used primitive ⩽, postulated to be transitive onL (the set of lotteries), to define the others with a different expression for <: [x < y ⇔ (x ⩽ y and noty ⩽ x)]. Thus, ⩽ and > are not necessarily complementary onL; since ⩽ is not postulated to be connected onL, but connected ⩽ is necessary and sufficient for such complementarity. Since the restriction of ⩽ to the subsetA ofL is connected, ⩽ and > are complementary onA. (4) Fishburn used primitive < onA to define the others with different expression for ~ and ⩽: [x ~ y ⇔ (notx < y and noty < x)]; [x ⩽ y ⇔ (x < y orx ~ y)]. His version of Savage's theory then assumed that < is asymmetric and negatively transitive onA. Thus, ⩽ and > are complementary, since asymmetric < is necessary and sufficient for such complementarity. (5) This analysis provides a new proof that the same list of elementary properties of binary relations onA applies to all three theories: ⩽ is connected, transitive, weakly connected, reflexive, and negatively transitive; while both < and > are asymmetric, negatively transitive, antisymmetric, irreflexive, and transitive; but only ~ is symmetric.     

Signed orders in linear and nonlinear utility theory

Self-reflecting signed orders on a set A and its anti-set A ^* were introduced previously as a way to account for negative as well as positive feelings about the inclusion of items in A in potential subsets of choice. The present paper extends the notion of signed orders to lotteries on A A ^*, describes reflection axioms for the lottery context, and shows how these axioms simplify utility representations for preference between lotteries. The simplified representations are then used to guide procedures for extending preferences from A A ^* and its lotteries to preferences between subsets of items.     

Helping Field Instructors Become More Effective Group Work Educators

Process recording can be a powerful tool for strengthening the link between theory and practice in group work education. The S.O.D.A. recording form (Summary, Observation, Developmental stage, Assessment) was developed by the authors as a tool for helping students and field instructors conceptualize group work practice. The article describes the S.O.D.A. format and its potential effectiveness in overcoming contemporary obstacles in group work field education. The need for a broad strategy involving collaborative efforts to promote and strengthen group work education in the classroom and the field is also discussed.     

Children’s reasoning about unequal gender‐based distributions

Children ages 7 (N = 56, M_age = 7.24, SD = 0.83), 9 (N = 55, M_age = 9.25, SD = 0.52), and 11 (N = 52, M_age = 11.60, SD = 0.79), and emerging adults (N = 50, M_age = 20.76, SD = 0.87) judged distributions of different items to boys and girls, when the items distributed varied by gender valence (related or unrelated to gender norms) and equivalency (equivalent or unequal). Distributions were judged to be acceptable most when the items were consistent with gender norms, especially for participants at ages 7 and 9, indicating that in middle childhood, children judge unequal treatment as fair when it is related to gender norms. Items were judged to be more likable when they were gendered, and likability judgments predicted more positive evaluations of the distributions, even when controlling for age.     

Caregivers' Coping and Self-Forgiveness After the Death of a Care-Receiver

ABSTRACT

This study explores the relationship of self-forgiveness with adaptive coping and nonadaptive coping. This study addresses self-forgiveness as part of the grieving process of Alzheimer's disease caregivers. One hundred and thirty-three caregivers who had recently lost a loved one were surveyed. The bivariate analysis revealed a significant relationship between self-forgiveness and adaptive coping and non-adaptive coping. Furthermore, stepwise regression models computed for the study variables revealed that adaptive coping and non-adaptive coping were statistically significant in explaining the variation in self-forgiveness. Based on these findings, future directions in research are explored.     

Parenting Style and Religiosity as Predictors of Antisocial Behavior Among Nigerian Undergraduates

Abstract

The relationship between parenting style, religiosity and antisocial behavior (ASB) was investigated in this study. Participants were 228 (120 males and 108 females) undergraduates. Participants’ age ranged from 16 to 20?years (M?=?18.9?years). They responded to the ASB scale, Parental authority questionnaire and centrality of religiosity scale. The study utilized a cross-sectional design and hierarchical regression was used for data analysis. Results showed that the model of the three dimensions of parenting styles (i.e., authoritarian, authoritative and permissive) predicted ASB and accounted for additional 11.2% variance in ASB over and above the control variables. However, only authoritarian (β?=?0.13, p?=?0.043) and permissive (β?=?0.32, p?β?=?0.25, p?相似文献   

The Effects of South Korean Social Workers' Professional Resources on their Understanding of a Patient's Right to End‐of‐Life Care Decisions in Long‐term Care Facilities

The aims of this study were to examine South Korean social workers' understanding of a patient's right to end‐of‐life care decisions (EOLCD) in long‐term care facilities and to explore the effectiveness of their professional resources in their understanding of this issue. A survey was conducted of 297 social workers from multiple long‐term care facilities in South Korea using structured questionnaires and face‐to‐face interviews. A multiple regression model was used, controlling for gender and religion. The participants' professional resources were measured by years of work, license type, number of beds, knowledge of advanced directives, experience in the EOLCD process, and training. The results demonstrated that South Korean social workers' understanding of a patient's right to EOLCD was moderate (mean 3.46), and their general (β = 0.576, P < 0.001) and medical knowledge (β = 0.117, P < 0.001) of advance directives, experience in the EOLCD process (β = 0.222, P < 0.001), and training (β = 0.028, P < 0.001) positively and significantly increased their understanding of patient rights (R² = 0.449, P < 0.001). The findings suggested that the development of academically supported and legally enforced standards and regulations for an EOLCD practice manual for long‐term‐care social workers would be beneficial.     

On the Relative Strengths of Altruism and Fairness

Some researchers have attributed deviations from selfish behavior to fairness. Violations of fairness theories, however, are observed in experimental dictator games with transfer rates greater than 1 (a transfer of x from the dictator yields an income of tx for the beneficiary, where x < tx): the dictator’s final income is less than the beneficiary’s. We theoretically propose that dictator giving also involves altruism, further supporting our claim with empirical evidence from four separate samples of dictator game experiments. Our nonlinear specification allows the relative measurement of the independent motives in dictator behavior.     

Target Rules for Public Choice Economies on Tree Networks and in Euclidean Spaces

We consider the problem of choosing the location of a public facility either (a) on a tree network or (b) in a Euclidean space. (a) (1996) characterize the class of target rules on a tree network by Pareto efficiency and population-monotonicity. Using Vohra's (1999) characterization of rules that satisfy Pareto efficiency and replacement-domination, we give a short proof of the previous characterization and show that it also holds on the domain of symmetric preferences. (b) The result obtained for model (a) proves to be crucial for the analysis of the problem of choosing the location of a public facility in a Euclidean space. Our main result is the characterization of the class of coordinatewise target rules by unanimity, strategy-proofness, and either replacement-domination or population-monotonicity.
