In the first issue of Significance , Roland Caulcutt suggested that a common feature of many successful companies is their development of a "management-by-fact" culture. He further suggested that such a culture requires that managers focus on processes, and that control charts be used at all levels throughout the organisation. In this follow-up article he explains how the various types of control chart are set up and used in practice. 相似文献

We compare the patterns of household division of labor in Germany and Israel—two countries that share key elements of the corporatist welfare regime but differ in their gender regimes—and evaluate several hypotheses using data from the 2002 International Social Survey Program. Although time constraints and relative resources affect the division of household labor and women’s housework in both societies, we find that in Germany the gender order of household labor is more rigid, whereas in Israel the spouses’ linked labor market status exerts distinctive effects. We also find significant relationships between gender ideology and the division of household labor. We discuss the theoretical advantages of approaching the comparative study of gender inequality from the vantage point of family and gender regimes. 相似文献

The authors examined nineteen nonprofit performing arts organizations, investigating the distribution of influence among organizational members, the grouping of volunteers and staff in organizational structures, and the effectiveness of the organizations. The organizations' effectiveness was assessed using multiple performance indicators. The analysis revealed five groupings or configurations of influence, which correlated to the organizations exhibiting the highest and lowest levels of organizational effectiveness. The authors conclude that a variety of structures are associated with good performance but structural dysfunctions are associated with organizational failure, and that members' commitment to an organization's structure is an important element of success. 相似文献

This study examines the possibility that estimation of the effect of breast-feeding on infant survival is affected by selection bias, in that children who are healthier at birth may be more likely to be breast-fed. Data are from the 1976 Malaysian Family Life Survey. "Ordinary logit models for breast-feeding and survival are estimated, and the results suggest that selection is indeed present. For example, children of higher birth weight appear to be more likely to be breast-fed and likely to survive. In addition, weight at birth and the duration of breast-feeding appear to be linked." Using birth weight as an indicator for the child's health, the authors conclude that "the direct influence of breast-feeding on survival remains of overwhelming importance even after corrections for selection bias are made." 相似文献

With the passage of the Patient Protection and Affordable Care Act (ACA) of 2010, the health insurance literacy of Americans became a critical issue. In response, a consumer education program was created and tested by university researchers and educators associated with Cooperative Extension. This article draws extensively on the emerging literature on health insurance literacy and on data from participants in the Smart Choice Health Insurance? program. The intent of the study was to understand socio-demographic and environmental variables that predict initial health insurance literacy and gains in health insurance literacy. A standardized instrument measuring health insurance literacy was used to collect the data. Multivariate analysis showed higher income consumers demonstrated greater initial health insurance literacy scores compared to middle income consumers, whereas younger, male and lower educated consumers reported lower initial health insurance literacy. After participating in the Smart Choice Health Insurance? program, consumers who made greater gains in their health insurance literacy tended to be female, higher income, and consumers residing in states that showed supportiveness of the ACA. The findings highlight the importance of considering sociodemographic characteristics in program design and delivery, as well as how contextual issues, such as the political environment, might impact the delivery of educational efforts. Findings from the analyses help inform ways to adapt and tailor educational opportunities that focus on health insurance literacy for a range of consumers. 相似文献

We treat robust M-estimators for independent and identically distributed Poisson data. We introduce modified Tukey M-estimators with bias correction and compare them to M-estimators based on the Huber function as well as to weighted likelihood and other estimators by simulation in case of clean data and data with outliers. In particular, we investigate the problem of combining robustness and high efficiencies at small Poisson means caused by the strong asymmetry of such Poisson distributions and propose a further estimator based on adaptive trimming. The advantages of the constructed estimators are illustrated by an application to smoothing count data with a time varying mean and level shifts. 相似文献

This paper deals with job search strategies and wages among cross‐border commuters residing in the Central European Region (CENTROPE). Our main aim is to investigate the role of social networks as constitutive for job searching and for successful labor market integration. We build upon a theoretical framework developed by Aguilera and Massey, reflecting on the nexus of social networks, job search methods, and related labor market outcomes. Methodologically, we use a new quantitative survey on the employment careers of cross‐border commuters residing in the regions of the Czech Republic, Slovakia, and Hungary bordering on Austria, conducted in the winter/spring of 2012/2013 (N = 2,573). Our results corroborate the hypothesis that human and social capital resources as well as labor market characteristics serve as key factors for job search and labor market integration among cross‐border commuters in the CENTROPE transnational labor market. 相似文献

Western societies have experienced an increasing flexibilization and deregulation of their labour markets in the last decades. These developments led to an expansion of non-standard work as well as low-paid employment. Nevertheless, there has been little systematic research on flexibilization and low-paid employment in Austria. Against this background, we discuss the growth of low-wages in Austria and analyse which social groups are especially affected by lowpaid work, using data from EU-SILC as well as ECHP for the years 1996–2010. While we find that those with better qualification tend to be better protected against low-pay risks, our results underline that employees in personal services and hospitality industry as well as non-standard workers are increasingly exposed to low-pay risks in the last 15 years. 相似文献

Rhetoric and Reality of Economic Self-sufficiency Among Rural,Low-Income Mothers: A Longitudinal Study 总被引:3,自引:3,他引:0

This study examined the contributions of maternal labor force participation and marital status on economic self-sufficiency
over time for rural mothers. Data were from 174 rural families participating in three waves of data collection in Rural Families Speak. χ
2 and multiple logistic regression were utilized. Results revealed only one-third of mothers moved toward economic self-sufficiency
over three years. Maternal education, employment status, and weekly work hours were associated with improved economic well-being.
Compared to single-parent families, unmarried-couple and married-couple families had increased odds of improving economically.
In an analysis of all mothers with partners, married or unmarried, martial status was not significant in economic improvement.
Findings suggest the role of marriage in welfare reform for rural families should be reconsidered.

We propose a phase I clinical trial design that seeks to determine the cumulative safety of a series of administrations of a fixed dose of an investigational agent. In contrast with traditional phase I trials that are designed solely to find the maximum tolerated dose of the agent, our design instead identifies a maximum tolerated schedule that includes a maximum tolerated dose as well as a vector of recommended administration times. Our model is based on a non-mixture cure model that constrains the probability of dose limiting toxicity for all patients to increase monotonically with both dose and the number of administrations received. We assume a specific parametric hazard function for each administration and compute the total hazard of dose limiting toxicity for a schedule as a sum of individual administration hazards. Throughout a variety of settings motivated by an actual study in allogeneic bone marrow transplant recipients, we demonstrate that our approach has excellent operating characteristics and performs as well as the only other currently published design for schedule finding studies. We also present arguments for the preference of our non-mixture cure model over the existing model. 相似文献
