Desirable system performance in the face of threats has been characterized by various management concepts. Through semistructured interviews with editors of journals in the fields of emergency response and systems management, a literature review, and professional judgment, we identified nine related and often interchangeably used system performance concepts: adaptability, agility, reliability, resilience, resistance, robustness, safety, security, and sustainability. A better understanding of these concepts will allow system planners to pursue management strategies best suited to their unique system dynamics and specific objectives of good performance. We analyze expert responses and review the linguistic definitions and mathematical framing of these concepts to understand their applications. We find a lack of consensus on their usage between interview subjects, but by using the mathematical framing to enrich the linguistic definitions, we formulate comparative visualizations and propose distinct definitions for the nine concepts. We present a conceptual framing to relate the concepts for management purposes. 相似文献

Revolutionary theorists are currently immersed in a critical debate about the future of the field. Allinson has argued that a fifth generation of revolutionary theory has passed us by without our noticing, while I have contended that it is revolutionary theory's fourth generation that is decidedly imperilled. Ritter and Beck – for their part- contend that we should reject the very idea of theoretical ‘generations’, and instead think of progress in revolutionary theory as a series of ongoing and settled debates about certain key topics. The pair contend that revolutionary theory has reached a consensus on two core debates: defining our object of study and determining appropriate methods. Contrary to this position, I argue that while there is much to praise about rejecting generational imagery, doing so necessarily entails that we also critique the self-proclaimed ‘fourth generation' with which such imagery is intertwined. Furthermore, I argue that there does not yet exist consensus among revolutionary theorists about a single definition of revolution, or on the question of which methods to use. Finally, I call for a regeneration of revolutionary theory which moves genuinely beyond the generational mythologies of the past. 相似文献

Although getting married is no longer a requirement for social acceptance, most people do marry in their lifetimes, and couples across the socioeconomic spectrum wish their marriages to be satisfying and long lasting. This review evaluates the past decade of research on the determinants of satisfaction and stability in marriage, concluding that the scholarship of the past 10 years has undermined three assumptions that were formerly accepted as conventional wisdom. First, research exploiting methods such as latent class growth analyses reveal that, for most couples, marital satisfaction does not decline over time but in fact remains relatively stable for long periods. Second, contrary to predictions of behavioral models of marriage, negative communication between spouses can be difficult to change, does not necessarily lead to more satisfying relationships when it is changed, and does not always predict distress in the first place. Third, dyadic processes that are reliably adaptive for middle-class and more affluent couples may operate differently in lower income couples, suggesting that influential models of marriage may not generalize to couples living in diverse environments. Thus, the accumulated research of the past 10 years indicates that the tasks of understanding and promoting marital satisfaction and stability are more complex than we appreciated at the start of the decade, raising important questions that beg to be answered in the years ahead. 相似文献

Over the last few years, marijuana has become legally available for recreational use to roughly a quarter of Americans. Policy makers have long expressed concerns about the substantial external costs of alcohol, and similar costs could come with the liberalization of marijuana policy. Indeed, the fraction of fatal accidents in which at least one driver tested positive for tetrahydrocannabinol has increased nationwide by an average of 10% from 2013 to 2016. For Colorado and Washington, both of which legalized marijuana in 2014, these increases were 92% and 28%, respectively. However, identifying a causal effect is difficult due to the presence of significant confounding factors. We test for a causal effect of marijuana legalization on traffic fatalities in Colorado and Washington with a synthetic control approach using records on fatal traffic accidents from 2000 to 2016. We find the synthetic control groups saw similar changes in marijuana-related, alcohol-related, and overall traffic fatality rates despite not legalizing recreational marijuana.

AbstractObjective: The current study examined the role of family influences on the vaccine behavior of emerging adults. Participants: In Spring 2017, we conducted anonymous online surveys of undergraduate students (n?=?608) at a large, public university in the mid-Atlantic. Methods: Logistic regression was used to examine associations between family factors and students’ awareness of the HPV vaccine, vaccine receipt, and vaccine intentions. Family factors included sex communication, religiosity, parental monitoring, family structure, and parents’ birthplace. Results: More comprehensive family sex communication is associated with less uncertainty regarding HPV vaccine receipt and greater likelihood of being already vaccinated. More frequent family religiosity and more parental monitoring are associated with greater likelihood of having decided against vaccination rather than already being vaccinated. Significant gender and racial disparities exist. Conclusion: Further research, policy, and programmatic intervention are needed to reduce disparities and to improve emerging adults’ compliance with HPV vaccine recommendations. 相似文献

In 2016, without the knowledge of its citizens, Baltimore City Police deployed a military aerial surveillance technology called Wide Area Motion Imagery (WAMI), which can track the movements of every person in public view over the entire city. Though the trial of the “spy plane,” as the program was dubbed, quickly ended in scandal, organizers from Baltimore’s low-income minority neighborhoods successfully rebooted the program in 2020, this time framing WAMI partly as a tool of “sousveillance” (watching “from below”) that can track the movements of police officers. The paper shows how organizers “rebranded” WAMI around two conceptions of sousveillance—“citizen-centered” and “state-centered”—creating an unlikely coalition of supporters from both pro- and anti-policing sides of the criminal justice reform debate. But while the renewed program has vowed to be a “Big Brother” to the state, it will continue to be used for traditional surveillance, raising troubling questions about privacy. The article sheds light on the politics of watching and being watched in the era of technology-driven criminal justice reform. 相似文献

Early maternal resolution with preterm birth was assessed at one month corrected age (CA), and potential maternal and infant characteristics that may be associated with early resolution were examined. Fifty‐five mothers of preterm infants (≤34 weeks) participated. Data regarding pregnancy, prenatal risk, delivery, infant's medical risk, maternal well‐being status, and infant's early developmental status were collected. Resolution was examined using the Reaction to Diagnosis Interview (RDI). A total of 38.2% of the mothers were classified as resolved. Only completion of antenatal corticosteroids (ACS) treatment and high prenatal risk significantly predicted maternal resolution. Early maternal resolution of preterm birth is associated with early knowledge regarding the preterm birth. 相似文献

Using micro‐level thermostat data from 27,000 U.S. households, we analyze how home heating/cooling decisions respond to weather. Responses are greater for extreme heat than for extreme cold and persist for at least 30 days after exposure, due in part to transaction costs but also to changes in intrinsic preferences. Failure to understand habit can lead us to overestimate the impact of short‐term policy nudges but underestimate the long‐run impact of small changes. Higher frequency estimates of how behavior responds to weather improve our understanding of climate adaptation as climate change affects not only mean temperatures but also variances.

ABSTRACTSocial work education has embraced a major shift towards competency based education. A core component of competency based education is that students must actually demonstrate competence. The ability to define terms or even to explain principles of effective social work practice is no longer sufficient. In this vein, social work educators are tasked with providing students a means of demonstrating an ability to practice necessary social work skills. Digital badges are a recent trend in higher education that can facilitate the shift towards competency based education. With this shift in mind, this paper outlines the requirements and benefits of a self-care badge. Students who completed the self-care badge completed readings on self-care, completed self-assessments and worksheets, developed written self-care plans, enacted the plans, monitored progress and completed a final report on the self-care practices. Overall, students described the benefits of the badge and the focus on actually practicing self-care rather than simply increasing their knowledge about self-care. 相似文献
