The COVID-19 pandemic has highlighted the importance of childcare to national economies in general and women's economic participation in particular, spurring renewed interest in childcare policy in many countries that have implemented lockdowns. This paper adopts a circle of care framework to analyzes how COVID-19 has affected paid childcare, unpaid childcare and other paid work, and the relationship between these sectors. Analysis is grounded in the lived experiences of parents and childcare educators, documented through 16 semi-structured interviews during the initial lockdown (March–June 2020) in British Columbia, Canada. Experiences from educators suggest their safety was not prioritized, and that their contributions were undervalued and went unrecognized. Mothers, who provided the majority of unpaid care, not only lost income due to care demands, but struggled to access necessities, with some reporting increased personal insecurity. Those attempting to work from home also experienced feelings of guilt and distress as they tried to manage the triple burden. Similarities of experiences across the circle of care suggest the COVID-19 childcare policy response in BC Canada downloaded care responsibilities on to women without corresponding recognition or support, causing women to absorb the costs of care work, with potential long-term negative effects on women's careers and well-being, as well as on the resilience of the circle of care. Pandemic recovery and preparedness policies that aim to promote gender equality must consider all sectors of the circle of care and the relationships between them.  相似文献

The framework for a unified statistical theory of spline regression assuming fixed knots using the truncated polynomial or “+” function representation is presented. In particular, a partial ordering of some spline models is introduced to clarify their relationship and to indicate the hypotheses that can be tested by using either standard multiple regression procedures or a little-used conditional test developed by Hotelling (1940). The construction of spline models with polynomial pieces of different degrees is illustrated. A numerical example from a chemical experiment is given by using the GLM procedure of the statistical software package SAS (Barr et al. 1976).  相似文献

Baseball performances are an imperfect measure of baseball abilities, and consequently exaggerate differences in abilities. Predictions of relative batting averages and earned run averages can be improved substantially by using correlation coefficients estimated from earlier seasons to shrink performances toward the mean.  相似文献

Interaction is very common in reality, but has received little attention in logistic regression literature. This is especially true for higher-order interactions. In conventional logistic regression, interactions are typically ignored. We propose a model selection procedure by implementing an association rules analysis. We do this by (1) exploring the combinations of input variables which have significant impacts to response (via association rules analysis); (2) selecting the potential (low- and high-order) interactions; (3) converting these potential interactions into new dummy variables; and (4) performing variable selections among all the input variables and the newly created dummy variables (interactions) to build up the optimal logistic regression model. Our model selection procedure establishes the optimal combination of main effects and potential interactions. The comparisons are made through thorough simulations. It is shown that the proposed method outperforms the existing methods in all cases. A real-life example is discussed in detail to demonstrate the proposed method.  相似文献

As a result of a recent federal government mandate, an increasing number of hospitals have decided to adopt electronic medical record (EMR) systems. This initiative is expected to lead toward more efficient and higher quality health care; however, little is known about governance characteristics and organizational performance for EMR adopters. Our goal is to inform theory and practice by examining hospitals with a sophisticated EMR and comparing those hospitals to similar hospitals (with a less sophisticated EMR) to understand the association between information technology (IT) governance characteristics and the implications on financial performance. Leveraging elements of the upper echelon theory, we posit that hospitals in which the chief information officer (CIO) reports to the chief executive officer, CIO turnover is low, and an IT steering committee is present are more likely to have a sophisticated EMR. We argue that EMR sophistication leads to improved financial performance. Our results underscore the importance of continuity in the CIO position on successful EMR implementations. Results also show that hospital size and financial performance are strongly associated with EMR sophistication. In addition, we find that a sophisticated EMR appears to be a fundamental element in improving hospitals’ revenue cycle management. Moreover, we find that hospitals with a sophisticated EMR appear to be more profitable. Finally, we observe that total payroll expense adjusted by total discharges drops among the sophisticated hospitals, potentially due to an increase in employee productivity. These insights can serve as a basis for tempering expectations relative to the financial impact of EMR adoption.  相似文献
