The southern pine beetle (SPB) is among the leading biological agents killing southern pine species in the eastern United States. In light of recognized spatiotemporal autocorrelation in SPB outbreaks, we devise a spatiotemporal block bootstrapping method that can be applied to analyze spatiotemporally dependent infestations. We also identify the relevant risk determinants and evaluate their impacts on the frequency of SPB outbreaks. For example, we find forest type, climate, and natural disasters like storm and forest management are all significantly associated with SPB risks. Using the results of a statistical model, we design a county-level group index insurance plan that generates estimates of actuarially fair premium rates for timber stands containing southern pine species. Given that no government-provided compensation scheme for SPB epidemics currently exists, application of this new insurance product could reduce forest owners losses. Our study offers an approach to analyzing and protecting against risks of other destructive pests affecting the timber sector. 相似文献

Service workers are expected to maintain high‐quality service delivery despite customer mistreatment—the poor‐quality treatment of service workers by customers—which can be demeaning and threatening to self‐esteem. Although service work is increasingly delivered by middle‐aged and older workers, very little is known about how employees across the age range navigate abuse from customers on the job. Does advancing age help or hinder service performance in reaction to customer mistreatment? Drawing on strength and vulnerability integration theory, we proposed that age paradoxically both helps and hinders performance after customer mistreatment, albeit at different stages. We tested our proposed model in a two‐sample field investigation of service workers and their supervisors using a time‐lagged, dyadic design. Results showed that age heightens the experience of self‐esteem threat but, nevertheless, dampens reactions to self‐esteem threat, leading to divergent effects on performance at different stages. Implications for age and service work, as well as aging and the sense of self, are discussed. 相似文献

The legalization of graffiti in many cities has impacted urban landscapes and the way artists and the public view graffiti, street art and the city as well. This article considers the genesis, process and consequences of legal walls programmes firstly by introducing and differentiating the key terms ‘graffiti’, ‘street art’ and ‘legal walls’, then by examining an empirical case, that of Singapore. Renowned as a graffiti‐averse and litter‐free city, Singapore's recent about‐turn in legalizing illicit art forms illustrates changing government perspectives on creativity and legality in the country. Why the government has effected this change, how artists and members of the public have responded to it and the resultant art forms are critically explored. The conclusion reflects on four key lessons from Singapore for cities in general. 相似文献

This paper is amongst the first to examine coopetition strategy for sustainable development at the network level. Companies who want to successfully implement complex innovative technologies that support sustainable development need to collaborate with other actors of the innovation ecosystem, including their competitors, so that they can develop standards, interoperable products, pool knowledge, and resources and bundle forces to compete against other technologies. Collaboration with competitors brings benefits, but also many risks. We investigated how firms cope with these risks when establishing an innovation ecosystem to implement a new technology in society. We conducted research in the Dutch smart grids sector and explored how these firms minimize inherent risks of coopetition. We found that system‐building actors in the Dutch smart grid field not only minimize inherent risks, but from the start of their collaboration they implement so‐called enablers to prevent these risks upfront. 相似文献

The observed racial/ethnic gap in bank account ownership among older adults is substantial. We investigate socioeconomic, cognitive, and cultural barriers underling it. As additional potential barriers are accounted for, the residual gaps in financial inclusion with respect to Whites are reduced by 19% for blacks and 46% for Hispanics. We find that citizenship and “taste for privacy” play a limited role for both minority groups, while real asset ownership, health, cognitive ability, and cultural hurdles contribute substantially to the gap. For Hispanics, language barriers explain most of the gap, while neighborhood‐level socioeconomic characteristics are more salient for blacks. We also examine how the racial/ethnic composition of couples influences financial decisions. We estimate a significantly smaller residual gap between “mixed” and white couples than between minority and white couples. We provide empirical evidence suggesting that, other things equal, mixed couples are less concerned with the cultural/psychological barriers facing minority couples. 相似文献

ABSTRACTRapid technological advancements have led to the emergence of smart services and smart consumers. This study focuses on smart consumers who voluntarily engage in value creation activities, in order to conceptualise smart experience co-creation (SEC) and the smart servicescape. Drawing on the Stimulus-Organism-Response (SOR) framework, a model is proposed and tested around the impacts of smart servicescape dimensions (aesthetics, superior functionality, social presence, perceived interactivity and perceived personalisation) on smart consumer experience co-creation. SEC is conceptualised as a second-order construct consisting of cognitive, hedonic, social/personal, and pragmatic/economic first-order dimensions. Results show that the technological environmental cues of the smart servicescape (S) collectively influence smart experience co-creation (O), and this co-created experience eventually influences consumers’ service brand equity and word-of-mouth (WOM) intentions (R). A major novelty of this study lies in uncovering the relationship between experience co-creation and service brand equity. Findings have theoretical and managerial implications for smart services. 相似文献

Marketers are beginning to expand the roles that celebrities play in support of brands. Connections now go beyond the typical endorsement relationship to employing celebrities as Creative Directors. Study 1 demonstrates celebrity Creative Directors, as opposed to merely endorsers, result in increased attitudes toward the advertisement; an effect mediated by consumer perceptions of celebrity expertize and attenuated by skepticism toward advertising. Study 2 further investigates this phenomenon by considering whether it is the title of Creative Director that results in increased attitudes toward the advertisement or if consumers need to be made aware of the responsibilities associated with such a role. Results from Study 2 suggest that merely bestowing a celebrity with the title of Creative Director is not sufficient to enhance attitudes, the duties performed by the celebrity Creative Director must be made explicit. 相似文献
