In 2020, Australia's successful COVID-19 public health restrictions comprised a national “initial lockdown” (March–May) and “ongoing lockdown” (July–November) for metropolitan Victorian residents only. We evaluated associations between ongoing lockdown and family finances and mental health. In the June and September 2020 Royal Children's Hospital National Child Health Polls, caregivers of children in Victoria and New South Wales (NSW) reported the following: job/income loss; material deprivation (inability to pay for essential items); income poverty; mental health (Kessler-6); perceived impact on caregiver/child mental health; and caregiver/child coping. Data from caregivers (N = 1207/902) in June/September were analysed using difference-in-difference modelling (NSW provided the comparator). During Victoria's ongoing lockdown, job/income loss increased by 11% (95%CI: 3%–18%); Kessler-6 poor mental health by 6% (95%CI: −0.3%–12%) and perceived negative mental health impacts by 14% for caregivers (95%CI: 6%–23%) and 12% for children (95%CI: 4%–20%). Female (vs. male) caregivers, metropolitan (vs. regional/rural) families, and families with elementary school-aged children (vs. pre-/high-school) were the most affected. The ongoing lockdown was associated with negative experiences of mental health, employment and income, but not deprivation or poverty, likely because of government income supplements introduced early in the pandemic. Future lockdowns require planned responses to outbreaks and evidence-informed financial and mental health supports. 相似文献

A number of investigators have explored the use of value of information (VOI) analysis to evaluate alternative information collection procedures in diverse decision-making contexts. This paper presents an analytic framework for determining the value of toxicity information used in risk-based decision making. The framework is specifically designed to explore the trade-offs between cost, timeliness, and uncertainty reduction associated with different toxicity-testing methodologies. The use of the proposed framework is demonstrated by two illustrative applications which, although based on simplified assumptions, show the insights that can be obtained through the use of VOI analysis. Specifically, these results suggest that timeliness of information collection has a significant impact on estimates of the VOI of chemical toxicity tests, even in the presence of smaller reductions in uncertainty. The framework introduces the concept of the expected value of delayed sample information, as an extension to the usual expected value of sample information, to accommodate the reductions in value resulting from delayed decision making. Our analysis also suggests that lower cost and higher throughput testing also may be beneficial in terms of public health benefits by increasing the number of substances that can be evaluated within a given budget. When the relative value is expressed in terms of return-on-investment per testing strategy, the differences can be substantial. 相似文献

With the global penetration of Internet technologies, individuals may now cross organizational boundaries to communicate efficiently with others regardless of time and space. Thus, when looking for help in solving work tasks, knowledge workers may just as easily contact individuals in rival firms across the globe as a coworker sitting at the next desk. As a result, management faces questions such as (1) How should firms manage employees' knowledge‐sourcing activities when they span both intra‐organizational and extra‐organizational boundaries, and (2) What is the relationship between different knowledge‐sourcing activities and individual performance? Grounded in the knowledge‐based view of the firm, we investigate these questions using data from Europe's largest information technology (IT) services and management consulting company. Our results provide evidence that organizations should support boundary spanning and knowledge sourcing from both internal and external sources. Results suggest (1) a positive relationship between boundary spanning communication and creativity and general performance, and (2) a negative relationship between a reliance on colocated coworkers as knowledge sources and creativity. 相似文献

Teachers are instrumental in antibullying efforts given their position of authority in the classroom context, yet teachers can only be effective at reducing victimization and bullying in their classrooms if they are aware of who is involved. Consequently, teachers’ attunement to bullies and victims is a critical component of social dynamics management and antibullying practices. Given the importance of teacher attunement, there is a pressing need to identify relevant factors related to the degree to which teachers are attuned to bullies and victims. The major objective of the current investigation was to examine student- (gender, popularity status), classroom- (average bullying, norm salience of bullying, popularity hierarchy, class size), and teacher-level (gender, teaching experience) factors associated with teachers’ attunement to bullies and victims. Using a sample of students in 5th-grade classrooms, we analyzed the likelihood of teachers being attuned to 267 bullies (76.8% boys) nested in 112 classrooms and 343 victims (55.1% boys) nested in 120 classrooms using multilevel mixed-effects generalized linear models. Results indicated that teachers were more likely to be attuned to boy bullies and victims but less likely to be attuned to bullies and victims with higher popularity status. No classroom or teacher level factors related significantly to the likelihood of teachers’ attunement. Implications for social dynamics management and bullying intervention efforts are discussed. 相似文献
