This study investigated the relationships between types of activity and quality of life (QOL) for older men and women at different ages. Based on cross-sectional data that included 220 community-dwelling elderly persons aged 65 and older in southern Taiwan, the results showed that the participation rates in many activities declined with age for both genders. Social activity and solitary leisure activity were significantly associated with QOL for old-old men, but not for young-old men. Only social activity was significantly associated with QOL for young-old women, but there was no significant association between any activity and QOL for old-old women. 相似文献

Federal and other regulatory agencies often use or claim to use a weight of evidence (WoE) approach in chemical evaluation. Their approaches to the use of WoE, however, differ significantly, rely heavily on subjective professional judgment, and merit improvement. We review uses of WoE approaches in key articles in the peer‐reviewed scientific literature, and find significant variations. We find that a hypothesis‐based WoE approach, developed by Lorenz Rhomberg et al., can provide a stronger scientific basis for chemical assessment while improving transparency and preserving the appropriate scope of professional judgment. Their approach, while still evolving, relies on the explicit specification of the hypothesized basis for using the information at hand to infer the ability of an agent to cause human health impacts or, more broadly, affect other endpoints of concern. We describe and endorse such a hypothesis‐based WoE approach to chemical evaluation. 相似文献

As medical and surgical advances improve, more young adults with congenital heart disease (CHD) are attending college. This case study illustrates some of the issues that these young adults may face as they attend college and discusses the role that college health practitioners can play in easing that transition. Participants: A case of a male with CHD presenting to the college health clinic with a new onset headache. Methods: The authors discuss some of the unique challenges that college health practitioners may face when caring for students with CHD. In addition, they make recommendations on how best to care for these patients and how best to coordinate care with CHD students other care providers. Results: This student with a history of coarctation of the aorta presented with new onset headaches and was found to have high blood pressure. He was diagnosed with recurrent coarctation, underwent percutaneous treatment with stenting and quickly resumed classes. Conclusions: As more students with CHD enter college, college health providers will need to understand some of the health risks that CHD students face. In addition, understanding some of the optimal ways to coordinate care with CHD providers can ease the transition that CHD students face as they enter college. 相似文献

Suppose an arbitrator needs to allocate an asset among two players, whose claims on the asset are incompatible. The allocation outcome is said to be fair if the arbitrator awards an outcome that brings the same utility payoff to the two players whenever the two players' claims are symmetric and the allocation set is symmetric. In conjunction with other natural axioms, this fairness requirement implies a unique allocation outcome for any claims problem. We propose a mechanism which can be used by the arbitrator to implement this allocation outcome, even when the players' preferences are unknown to the arbitrator. (JEL C78, D63, J52) 相似文献

Nonstationary time series are frequently detrended in empirical investigations by regressing the series on time or a function of time. The effects of the detrending on the tests for causal relationships in the sense of Granger are investigated using quarterly U.S. data. The causal relationships between nominal or real GNP and M1, inferred from the Granger–Sims tests, are shown to depend very much on, among other factors, whether or not series are detrended. Detrending tends to remove or weaken causal relationships, and conversely, failure to detrend tends to introduce or enhance causal relationships. The study suggests that we need a more robust test or a better definition of causality. 相似文献

Today's data-heavy research environment requires the integration of different sources of information into structured datasets that can not be analyzed as simple matrices. We introduce an old technique, known in the European data analyses circles as the Duality Diagram Approach, put to new uses through the use of a variety of metrics and ways of combining different diagrams together. This issue of the Annals of Applied Statistics contains contemporary examples of how this approach provides solutions to hard problems in data integration. We present here the genesis of the technique and how it can be seen as a precursor of the modern kernel based approaches. 相似文献

本文以新制度理论与交易成本理论进行对话,从合法性视角构建中国情境下制度环境、风险感知与供应链网络治理模式选择之间影响机理的理论模型。通过问卷调查的方式收集117份有效问卷,并采用结构方程模型方法实证检验制度环境、风险感知对供应链网络治理模式的"形塑"作用。研究结果表明,制度环境是影响供应链网络治理模式选择的重要因素,强制制度对供应链网络治理模式选择具有显著影响,规范制度的影响作用不显著。在供应链网络治理模式选择过程中关系风险感知具有完全中介作用,而绩效风险感知具有部分中介作用。 相似文献

《愤怒的葡萄》是约翰·斯坦贝克的代表作。小说讲述了在20世纪30年代美国经济萧条背景下,乔德一家人向加利福尼亚逃荒,以图获得美好的生活。然而,现实的残酷造成等待他们的仍然是饥荒、贫穷和失业,美梦的破碎导致成千上万像乔德这样的家庭奋起反抗。以权力话语理论为切入点,对小说中的主要人物进行解读,有助于实现微观权力和宏观权力的结合,进一步加深对小说的理解。 相似文献

选取我国三大经济区2001—2017年的数据,运用面板数据模型分析了政府财政、金融市场及其相互作用对区域自主创新能力提升的影响,结果表明:政府财政对自主创新能力的提升作用较金融市场更为显著,但三大经济区存在差异;就全国总体而言,金融支持效率指标在是否存在政府中介的情况下均不显著,金融市场对自主创新的支持效率还很低下;误差修正模型表明区域自主创新能力提升还受自身前期自主创新能力水平影响;人力资本的投入对区域自主创新能力的提升起到至关重要的作用。 相似文献
