The increase in weather and climate disasters in recent years has prompted an interest in analyzing their consequences and the mitigation and adaptation measures that can help minimize their potentially large impacts on individuals’ welfare. We match thirty-one billion-dollar disasters with individual survey data from the Behavioral Risk Factor Surveillance System to estimate the effect of extreme weather events on the subjective well-being of U.S. residents. Our results indicate that natural disasters have a negative and robust impact on subjective well-being in the affected communities, and that, on average, this impact peaks 6 months after the event, and then decays over time. We then investigate the attenuating impact of health care access, flood insurance, and governmental assistance programs and find a partial compensating role for risk-transfer and relief measures. We also find that stronger emotional and social support mitigates the negative impact of natural disasters. 相似文献

Aims: To examine healthcare resource utilization associated with refractory myasthenia gravis (MG) in England.Materials and methods: This was a retrospective cohort study of linked data from the Clinical Practice Research Datalink and the Hospital Episode Statistics database collected between 1997 and 2016. Included patients were ≥18?years of age at the index MG diagnosis. Patients with refractory MG were identified using an algorithm based on treatments received. Healthcare resource utilization since the index date was compared between refractory and non-refractory cohorts.Results: The study included 1149 patients with MG, of whom 66 (5.7%) were refractory. Sex and age at diagnosis did not significantly differ between the refractory and non-refractory cohorts. Rates of healthcare resource utilization per person-year were significantly higher (p?.05) for patients with refractory compared to non-refractory MG for GP visits, visits to other healthcare professionals, outpatient visits and inpatient hospitalization. Patients in the refractory cohort spent more total days hospitalized since the index visit than patients in the non-refractory cohort (median, 33 vs. 16?days [p?.0001]).Limitations: The algorithm for identifying refractory patients did not include clinical criteria. Also, treatments administered in hospitals or by specialists were not available in the databases.Conclusions: Patients in England with refractory MG more often visit healthcare providers, are hospitalized and visit an emergency room than patients with non-refractory MG. 相似文献

This study aims to broaden the current knowledge on the antecedents and consequences of customers’ psychological ownership (CPO) from new perspectives in the hotel context. Specifically, this study investigates how self-image congruity and functional congruity affect CPO through impression in memory based on self-congruity theory and also examines two types of customer engagement—customers’ social influence engagement and knowledge-sharing engagement—as new CPO outcomes. Using survey data collected from 433 Chinese hotel customers, this study finds that self-image congruity positively predicts CPO partially through impression in memory, whereas functional congruity positively influences CPO fully through impression in memory. Moreover, the findings indicate that CPO significantly drives customers’ social influence engagement and knowledge-sharing engagement. This study contributes theoretically to the CPO literature by further developing its linkages with congruity perceptions and customer engagement. Practical implications of the findings can help hotel managers effectively promote CPO and customer engagement. 相似文献

Deliberations about how to govern complex problems of urban health and wellbeing sustainably have often been implicitly biased by ideas such as being ‘human-scale’ or ‘people-centered.’ With increasing urban populations and increasing urban system interconnectivity, many cities have transformed into city regions or clusters, and the external effects of urban growth are carried mainly by the marginalized and the environment putting urban health increasingly at risk. Here we address the question of why human societies have not been better at collectively adapting to the challenges of urbanization and global environmental change? We build a theoretical framework of multi-level selection, complex systems evolution, and governance, following which we then present ‘human-scale’ and ‘people-centered’ ideas of urban development as expressions of two types of socio-political organization with different degrees of self-organization. We found several reasons for which the maladies of current urban development emerged and the seeming inability to resolve them. First, urban systems became increasingly interconnected and evolved into ultrasocial superorganisms, displaying preference to sustain themselves as a whole rather than their subordinates. Second, the difference in scaling effects between the biological and the social network contributed to the mismatch between rapid urban growth and slow adaptation. Furthermore, institutions of decreased variety reinforce themselves and become dominant, creating a positive feedback mechanism and promoting invasive and exploitative exponential growth, but they also reduce the creativity and resilience of urban systems. We also found that both the “human-scale” and the “people-centered” approaches acknowledge the exponential growth and decreasing variety in urban systems, and advocate for correcting the mismatches. To incorporate people's needs and values for long-term, truly sustainable urban health governance, we recommend combining the self-organizing, evolutionary feature of “human-scale” and the coordinative, political feature of “people-centeredness.” 相似文献

游客旅游行为失范时有发生,威胁着旅游资源与环境安全。心理归因影响个体行为逻辑,归因偏差是解释心理归因的经典理论。本文引入归因偏差理论,采用实证方法探究旅游行为失范背后的归因偏差因素,为减少旅游行为失范提供心理学依据。研究发现,归因偏差能够引致旅游者心理认知偏差,后者直接引发和助推旅游行为失范。心理环境和群体心理对引致旅游者的心理认知偏差和行为失范具有显著作用,归因偏差成为旅游者弱化旅游行为失范结果的心理屏障,可激发或促进旅游行为失范的发生或持续。研究认为旅游地可从完善硬件监控、控制游客流量、强化失范行为负面教育、发挥在场监督作用等方式削弱归因偏差效应。 相似文献

This paper examines how power affects consumers’ responses to corporate social responsibility (CSR) initiatives of luxury brands. The results of three studies show that high‐power individuals evaluated a luxury brand's CSR campaign more positively than low‐power individuals. High‐power individuals viewed CSR activities as being more fluent than low‐power individuals. This study further demonstrates that power influences consumers’ responses to nonluxury brand's CSR activities. Low‐power individuals, who are more receptive to warmth, evaluated nonluxury brand's CSR more favorably rather than high‐power individuals. 相似文献

Previous empowerment research has focused on subordinate perceptions of empowering leadership and its outcomes. Met‐expectations theory suggests that subordinate expectations of leader behaviours are essential in forming their a posteriori evaluations. To address the lack of investigation of individual expectations in the empowerment literature, in this study, we explore how subordinates' empowerment expectations and perceptions combine to influence their job satisfaction and psychological empowerment based on three alternative, theoretically derived met‐expectation models, namely, the disconfirmation model, the ideal‐point model, and the experiences‐only model. The results of a 2‐stage study of 114 respondents indicate that employees are more satisfied with their work when perceived empowerment exceeds expectations. However, both empowerment perceptions and expectations positively contribute to higher psychological empowerment. We then discuss implications and directions for future research. 相似文献

We investigate the role of contract volition and motives for accepting temporary employment in the relationship between precariousness of life and negative psychological symptoms in a sample of 275 Italian temps. Results suggest that the negative effect of contract volition on negative psychological symptoms is partially mediated by precariousness of life. A moderated mediation model shows that specific motives moderate the negative effects of contract volition on precariousness of life, so that when contract volition is higher, workers with weaker motives feel less precarious. This study broadens our understanding of temporary employment outcomes by showing that the negative consequences of precariousness of life seem to be less troublesome among temporary workers with higher contract volition and lower motivation. © 2018 ASAC.

Under pressures related to economic growth and environmental protection, China is facing an increasingly severe “environment–health–poverty” trap risk. Fuel taxation is generally considered an effective policy to counter such a risk. Since 2009 China has raised the fuel tax rate many times to enhance tax reform. However, the effects of this policy remain unknown. Therefore, it is vitally important to estimate the impacts of China's current fuel taxation policy on environment, public health and the national economy. As the first attempt in existing literature on China, this paper builds a general equilibrium framework with the feedback effect of public health on economy. We find that that the fuel tax policy benefits the adjustment of the economic structure and improves human health; however, it is detrimental to economic growth, public welfare and price stability. In this sense, it plays a limited role in reducing the trap risk and might not be sustainable in the long term. 相似文献
