While opioid prescribing rates have drawn researchers' attention, little is known about the mechanisms through which income inequality affects opioid prescribing rates and even less focuses on whether there is a rural/urban difference in mediating pathways. Applying mediation analysis techniques to a unique ZIP code level dataset from several sources maintained by the Centers for Medicare and Medicaid Services, we explicitly examine two mechanisms through residential stability and social isolation by rural/urban status and find that (1) income inequality is not directly related to opioid prescribing rates, but it exerts its influence on opioid prescribing via poor residential stability and elevated social isolation; (2) social isolation accounts for two‐thirds of the mediating effect of income inequality on opioid prescribing rates among urban ZIP codes, but the proportion halves among rural ZIP codes; (3) residential stability plays a larger role in understanding how income inequality matters in rural than in urban ZIP codes; and (4) beneficiary characteristics only matter in urban ZIP codes. These findings offer nuanced insight into how income inequality affects opioid prescribing rates and suggests that the determinants of opioid prescribing rates vary by rural/urban status. Future research may benefit from identifying place‐specific factors for opioid prescribing rates.  相似文献

This paper examines the impact of relative income on income satisfaction with given absolute income. We conducted an experiment in China where participants earned three different levels of income according to their relative performance in a task. While the treatment group was informed about their relative income, the control group only knew their own absolute income. We found that while controlling for absolute income and other factors, information about relative income increases the satisfaction of the high-income group and reduces the satisfaction of the low-income group. Relative income may interact with individual characteristics, such as gender, to affect income satisfaction. We also found that relative income treatment significantly increases income satisfaction inequality, primarily by causing social comparisons among different income groups, which has some welfare implications.  相似文献

The extant literature highlights numerous different factors influencing the timeliness and intensity of incumbent response to discontinuous technological change. However, this literature has so far not been synthesized and is therefore limited in its analytical, predictive, and normative power. We develop a comprehensive model of incumbent response that organizes different explanatory factors into the three distinct dimensions of (1) identification and interpretation, (2) decision making, and (3) organizational implementation. We also conceptualize how response intensity and timeliness affect business performance in new technological domains. We test the model against data from 320 firms from the German dental lab industry, finding substantial support for the majority of our hypotheses. This study offers unique empirical insight in observing that cognitive constructs such as framing and management flexibility have the strongest impact on both intensity and timeliness of incumbent response to technological, and thus, strategic discontinuities. Together, our findings have important implications for both theory and practice.  相似文献

Abstract

The ordered probit and logit models, based on the normal and logistic distributions, can yield biased and inconsistent estimators when the distributions are misspecified. A generalized ordered response model is introduced which can reduce the impact of distributional misspecification. An empirical exploration of various determinants of life satisfaction suggests possible benefits of allowing for diverse distributional characteristics. These improvements are confirmed using a Monte Carlo study to contrast the performance of the flexible parametric specifications to the probit and logit specifications.  相似文献

The issue of transracial adoption has been a controversial issue in foster care and adoption placement decisions. In 1994, the 104th Congress passed the Multiethnic Placement Act (MEPA), forbidding agencies receiving federal funds from solely considering race, culture, and ethnicity in making foster care and adoption placement decisions. Congress mandated that the Department of Health and Human Services (DHHS) develop policy guidelines for child placement agencies to follow. In April 1995, DHHS issued the guidelines that agencies were to follow. The authors of the paper discuss the MEPA, DHHS's policy guidelines for agencies and the guidelines' legal support, and the implications for social work practice in foster care and adoption placements.  相似文献

Abstract Multiple indicators of the structure of agriculture were extracted from the U.S. Census of Agriculture for the years 1982, 1987, and 1992, and used to extend previous work by Wimberley (1987). Exploratory factor analysis results for each year yielded three dimensions of agri-structure: corporate-commercial, farming-firm, and small-farm. Factor-scores used to estimate scales had high reliabilities (omega coefficients > .9) and strong inter-temporal correlations for each scale across years were observed. The content of each scale was consistent across the three years, suggesting that structural shifts in the elements defining “agri-structure” were minimal. Because the 1980s were a turbulent period for U.S. agriculture, the patterns describing heterogeneity among counties in each year were investigated. Cluster analysis of each year's three factor scales produced five homogeneous groups of counties: three, dominated respectively by small-farms, farming-firms, and corporate-farms and two mixed groups, which we interpreted as reflecting transitional situations. Comparisons of these cluster groupings across the three years identified the emergence of counties typified by organizational patterns of firm-oriented and corporate-commercial farming. Moreover, the patterns of temporal movement by U.S. counties across this typology suggest a fundamental change from homogeneous family-centered small-farming concentrations dominant during most of this century. Implications of the findings are discussed.  相似文献

Predictable patterns in early parent–child interactions may help lay the foundation for how children learn to self‐regulate. The present study examined contingencies between maternal teaching and directives and child compliance in mother–child problem‐solving interactions at age 3.5 and whether they predicted children's behavioral regulation and dysregulation (inhibitory control and externalizing behaviors) as rated by mothers, fathers, and teachers at a four‐month follow‐up (N = 100). The predictive utility of mother‐ and child‐initiated contingencies was also compared with that of frequencies of individual mother and child behaviors. Structural equation models revealed that a higher probability that maternal directives were followed by child compliance predicted better child behavioral regulation, whereas the reverse pattern and the overall frequency of maternal directives did not. For teaching, stronger mother‐ and child‐initiated contingencies and the overall frequency of maternal teaching all showed evidence for predicting better behavioral regulation. Findings depended on which caregiver was rating child outcomes. We conclude that dyadic measures are useful for understanding how parent–child interactions impact children's burgeoning regulatory abilities in early childhood.  相似文献

In contrast to younger populations, little attention has been paid to the increase in seniors using Internet-based venues to find relationships and the potential risk for adverse outcomes this poses. This study examined data collected via an online survey from 45 ethnically diverse women aged 50+ “seeking relationships” on MySpace. The majority of women reported a relationship with someone they met online (85%). They also reported experiencing adverse events including financial exploitation (40%), threats (55%), and physical harm (38%) by someone they met online at levels greater than traditional relationship seeking in the general population. Directions for future research are explored.  相似文献

Recent studies of the relationship between parenting and child development have included a focus on the parent's capacity to treat the child as a psychological agent. Several constructs have been developed to refer to this capacity, for example maternal mind-mindedness, reflective functioning, and parental mentalizing. In this review article, we compare and contrast different constructs from diverse theoretical backgrounds that have been developed to operationalize parental mentalizing. We examine the empirical evidence to date in support of each of the constructs and review the relevant measures associated with each construct. Next, we discuss the possibility that these apparently diverse constructs may tap into the same underlying neurobiological socio-cognitive system. We conclude by proposing a testable model for describing the links between parental mentalization, the development of mentalizing in children, and child psychopathology.  相似文献
