The purpose of this brief is to present several case vignettes that illustrate omissions in the investigation of elder deaths. These vignettes demonstrate the need for a standardized approach in the conduct of medicolegal investigations of fatal elder abuse. For each of the described oversights, a recommendation is offered to address the gap in investigation processes, which in turn could improve the determination of cause and manner of elder death. Inherent limitations of resources and practical realities of death investigation are discussed and recommendations are made for future research. Viewed broadly, deficiencies in elder death investigations can lead to the underreporting of elder abuse and the reduction of legal options for victims, which may reflect a systemic pattern of social injustice. 相似文献

Contrary to the general belief, systemic risk does not only regard the risk posed by balance sheet relationships and interdependencies among institutions. It also features a temporal dimension related to the inappropriate responses of financial market participants to changes in risk over time. This paper proposes a method to simultaneously address the cross-sectional and the time dimension in which systemic risk materializes. The method is based on the TOPHITS algorithm. It provides three scores, namely borrowing, lending and time scores: the first two represent the systemic importance of the borrowing and the lending activity associated with each financial institution,while the third represents an empirical Early Warning Signal of the financial crisis. Our findings reveal that the identification of the time score as an indicator for an incoming market distress could be relevant to design macro prudential policies. 相似文献

Research on early-life mortality in contemporary and historical populations has shown that infant and child mortality tend to cluster in a limited number of high-mortality families, a phenomenon known as ‘mortality clustering’. This paper is the first to review the literature on the role of the family in early-life mortality. Contemporary results, methodological and theoretical shortfalls, recent developments, and opportunities for future research are all discussed in this review. Four methodological approaches are distinguished: those based on sibling deaths, mother heterogeneity, thresholds, and excess deaths in populations. It has become clear from research to date that the death of an older child harms the survival chances of younger children in that family, and that fertility behaviour, earlier stillbirths, remarriages, and socio-economic status all explain mortality clustering to some extent. 相似文献

Drawing on the complementary assets framework, this study explores the moderating effect of innovation‐focused complementary assets (CA‐I) on the relationship between a data‐driven supply chain orientation (DDSCO) and firm financial performance. To test the moderating effect, survey data gathered from 329 manufacturing firms in China were analysed using a moderated regression analysis. The results indicate that DDSCO has a significant positive effect on financial performance, and that capabilities for product and process innovation function as complementary assets moderating the DDSCO–performance relationship. The findings suggest that innovation‐focused complementary assets are performance differentiators when paired with a DDSCO and explain why some firms obtain financial benefits from the development of a DDSCO while others do not. Specifically, competitive advantage from a DDSCO may not be realized unless CA‐I and potentially other complementary assets are harnessed, thus providing useful practical guidance to managers. Hence, the study provides empirical support for the complementary assets framework. 相似文献

This paper presents an inventory problem related to the one-period stochastic inventory (or “newsboy”) problem. In this problem, the firm has to decide how much product to order to meet a random one-period demand. The version of the problem presented is novel in two respects. First, demand is explicitly permitted to be negative, and second, the penalty (or shortage) cost is assumed to be independent of the magnitude of the shortage. This situation is shown to change the form of the cost function and to complicate the determination of optimal policies. The form of the optimal policy is developed, and two example problems are presented in some detail. 相似文献

This paper addresses the questions of market penetration and locational conflict in a franchise system of distribution. The models developed provide a means to evaluate alternative scenarios and the effects of various franchise policies. It is shown that the market penetration and location goals of the members of a franchise system coincide only under a very limited set of circumstances. 相似文献

While it is well known that the widowed suffer increased mortality risks, the mechanism of this survival disadvantage is still
under investigation. In this article, we examine the quality of health care as a possible link between widowhood and mortality
using a unique data set of 475,313 elderly couples who were followed up for up to nine years. We address whether the transition
to widowhood affects the quality of care that individuals receive and explore the extent to which these changes mediate the
elevated mortality hazard for the widowed. We analyze six established measures of quality of health care in a fixed-effect
framework to account for unobserved heterogeneity. Caregiving and acute bereavement during the transition to widowhood appear
to distract individuals from taking care of their own health care needs in the short run. However, being widowed does not
have long-term detrimental effects on individuals’ ability to sustain contact with the formal medical system. Moreover, the
short-run disruption does not mediate the widowhood effect on mortality. Nevertheless, long after spousal death, men suffer
from a decline in the quality of informal care, coordination between formal and informal care, and the ability to advocate
and communicate in formal medical settings. These findings illustrate women’s centrality in the household production of health
and identify important points of intervention in optimizing men’s adjustment to widowhood. 相似文献

Obesity is considered a major cause of premature mortality and a potential threat to the longstanding secular decline in mortality
in the United States. We measure relative and attributable risks associated with obesity among middle-aged adults using data
from the Health and Retirement Study (1992–2004). Although class II/III obesity (BMI _ 35.0 kg/m2) increases mortality by
40% in females and 62% in males compared with normal BMI (BMI = 18.5-24.9), class I obesity (BMI = 30.0-34.9) and being overweight
(BMI = 25.0-29.9) are not associated with excess mortality. With respect to attributable mortality, class II/III obesity (BMI
_ 35.0) is responsible for approximately 4% of deaths among females and 3% of deaths among males. Obesity is often compared
with cigarette smoking as a major source of avoidable mortality. Smoking-attributable mortality is much larger in this cohort:
about 36% in females and 50% in males. Results are robust to confounding by preexisting diseases, multiple dimensions of socioeconomic
status (SES), smoking, and other correlates. These findings challenge the viewpoint that obesity will stem the long-term secular
decline in U.S. mortality. 相似文献

In this study, I examine disparities in schooling progress among children born to immigrant and U.S.-born blacks. I find that
in one- and two-parent families, children born to black immigrants are less likely to fall behind in school than those born
to U.S.-born blacks. In two-parent immigrant families, children born to two immigrant parents have a significant schooling
advantage over children born to one immigrant parent. While children born to two immigrant parents in the wealthiest black
immigrant families do better in the second generation than in the first, the reverse is observed among children in less wealthy
families. These findings contribute in two ways to our understanding of the assimilation processes of children born to black
immigrant parents. First, they show that there is a positive association between the number of immigrant parents in a family
and children’s schooling performance. Second, they suggest that disparities in the assimilation patterns of the children of
black immigrants are a likely product of the interaction between their parental characteristics and the socioeconomic circumstances
of their families. 相似文献

Population forecasts entail a significant amount of uncertainty, especially for long-range horizons and for places with small
or rapidly changing populations. This uncertainty can be dealt with by presenting a range of projections or by developing
statistical prediction intervals. The latter can be based on models that incorporate the stochastic nature of the forecasting
process, on empirical analyses of past forecast errors, or on a combination of the two. In this article, we develop and test
prediction intervals based on empirical analyses of past forecast errors for counties in the United States. Using decennial
census data from 1900 to 2000, we apply trend extrapolation techniques to develop a set of county population forecasts; calculate
forecast errors by comparing forecasts to subsequent census counts; and use the distribution of errors to construct empirical
prediction intervals. We find that empirically-based prediction intervals provide reasonably accurate predictions of the precision
of population forecasts, but provide little guidance regarding their tendency to be too high or too low. We believe the construction
of empirically-based prediction intervals will help users of small-area population forecasts measure and evaluate the uncertainty
inherent in population forecasts and plan more effectively for the future. 相似文献
