After smoking, exposure to radon and its progeny is the second leading cause of lung cancer. The probability of inducing lung carcinomas by inhaled radon progeny depends on the deposited radiation dose, and is significantly affected by physiological and morphometric changes induced by smoking. Due to irritation of the airways, the inhalation of cigarette smoke leads to the hyperproduction of mucus. Two concurrent processes occur: on one hand, increased production of mucus protects the target cells against radiation damage; on the other hand, in the case of long-term smokers, a chronic lung obstruction develops, causing an increase in the radiation dose to the lungs. Depending on the duration and intensity of smoking, these processes contribute to the final radiation dose with different weights. The primary objective of this study was to investigate to what extent these smoke-induced changes can modify the resulting absorbed dose of inhaled radon progeny relative to healthy nonsmokers. Since the bronchial dose depends on the degree of lung tissue damage, we have used this dose as a tool for detecting the effects of smoking on the lung epithelium. In other words, the biological effect of radon served as a tracer of changes induced by smoking. 相似文献

This paper addresses the question whether regional mortality differences within developed countries reflect differences in characteristics of medical care service. It adds two new elements to previous studies on this subject: it concentrates on selected ‘avoidable’ causes of death, and it makes parallel analyses for ten EC countries. The results show that levels of medical care supply contribute little to the explanation of regional differences in mortality from the selected conditions. It is concluded that if regional mortality differences are related to health care, factors other than the level of supply are probably involved. 相似文献

We consider an incomplete markets economy with capital accumulation and endogenous labor supply. Individuals face countercyclical idiosyncratic labor and asset risk. We derive conditions under which the aggregate allocations and price system can be found by solving a representative agent problem. This result is applied to analyze the properties of an optimal monetary policy in a New Keynesian economy with uninsured countercyclical individual risk. The optimal monetary policy that emerges from our incomplete markets economy is the same as the optimal monetary policy in a representative agent model with preference shocks. When price rigidity is the only friction the optimal monetary policy calls for stabilizing the inflation rate at zero. 相似文献

This article reconstructs how, under the umbrella of the Europea Union (EU), discreet opportunities for EU social policy agenda setting opened for academic expertise from the late 1990s to the 2020s. This began with the Dutch presidency of the EU in the first half of 1997, endorsing the notion of ‘social policy as a productive factor’, followed by the 2000 Lisbon strategy for Growth and Social Cohesion in the open economy. The social investment landmark publication was Why We Need a New Welfare State, written by Gøsta Esping-Andersen et al., for the Belgian presidency of 2001. Ultimately, cumulative academic insights and feedback from country-specific reform experiences found their synthesis in the Social Investment Package in 2013. EU political codification of social investment took effect with the adoption of the European Pillar of Social Rights in December 2017. The paper concludes on the future for social investment with some personal reflections as an engaged scholar. 相似文献

Since about 1990, when sustainability became a key concept for a wide range of scientific disciplines, the need for multidisciplinary collaboration has increased. We present five illustrative cases from the long-standing environmental research work at the University of Groningen. The projects described are about hazardous materials risk, odor annoyance, energy scenario evaluation, climate decision analysis, and household consumption, respectively. The various case discussions emphasize experiences in research conceptualization, project design and execution, main findings, policy advice and surplus value, and difficulties met. Conclusions and recommendations are presented about the practice of multidisciplinary research. Finally, some challenges for research and development about environmental sustainability are discussed. 相似文献
