Arrow's axioms for social welfare functions are shown to be inconsistent when the set of alternatives is the nonnegative
orthant in a multidimensional Euclidean space and preferences are assumed to be either the set of analytic classical economic
preferences or the set of Euclidean spatial preferences. When either of these preference domains is combined with an agenda
domain consisting of compact sets with nonempty interiors, strengthened versions of the Arrovian social choice correspondence
axioms are shown to be consistent. To help establish the economic possibility theorem, an ordinal version of the Analytic
Continuation Principle is developed.

Asthma patients' health status may be especially sensitive to some types of air pollution, but the evidence on this is mixed. We explore the effects of ground-level ozone on asthma patient's activities, breaking apart the usual aggregated category of leisure into indoor and outdoor activities, and differentiating those by whether the activities were active or inactive. Applying the semiparametric censored estimation method we demonstrate that even though the period over which activities were observed was relatively low in ozone levels, there is a significant impact of ozone on a few activities. The (non-ozone) economic and demographic variables in the model play significant roles in explaining the allocation of time among seven activities, suggesting the suitability of the approach for other household decision-making contexts. 相似文献

The contemporary retreat from marriage in the United States has had a differential impact across socioeconomic and racial groups. Here, 1990 marriage rates and propensities for Virginia, North Carolina, and Wisconsin are analyzed regarding (a) the likelihood that persons in different groups ever marry and (b) patterns of partner choice with respect to race and educational level. Marriage remains strong in most race‐education groups but is substantially lower among Blacks and among those with less than 12 years of education. Patterns of partner choice have shifted to show greater symmetry between the educational levels of brides and grooms. Changes have been modest with regard to the level and pattern of interracial (Black‐White) marriage. Marriage is increasingly a union of equals, but a union chosen more by Whites than by Blacks and more by the well educated than by the poorly educated. 相似文献

西方资本主义生态现代化之路向是以全球性生态空间修复策略、时间修复策略掺杂生态霸权主义谋划而展现自身的生态叙事合法性的。它所证成的合理性,实质上不过是资本逻辑的生态隐性呈现及非正义剥夺。拒斥“资本丛林”成为新的生态文明创造的基本方向。从实践的生态本体论、认识论以及价值论出发,以构建“地球生命共同体”为鹄的,中国式现代化生态文明创造构筑了一个“人与自然是生命共同体”“人类命运共同体”“人与自然的生态伦理共同体”逐次展开的新路径。它摒弃人与自然对立关系的思维模式,建构了作为对象性的本质力量的生态主体性,塑造了以总体性环境正义为特征的伦理样态,实现了对资本主义生态空间生产的时代超越。中国式现代化生态文明创造的包容性与发展性为其能持续引领全球生态文明提供了可能。 相似文献

The 2003 Heat Wave in France: Dangerous Climate Change Here and Now 总被引:14,自引:0,他引:14
In an analysis of the French episode of heat wave in 2003, this article highlights how heat wave dangers result from the intricate association of natural and social factors. Unusually high temperatures, as well as socioeconomic vulnerability, along with social attenuation of hazards, in a general context where the anthropogenic contribution to climate change is becoming more plausible, led to an excess of 14,947 deaths in France, between August 4 and 18, 2003. The greatest increase in mortality was due to causes directly attributable to heat: dehydration, hyperthermia, heat stroke. In addition to age and gender, combinatorial factors included preexisting disease, medication, urban residence, isolation, poverty, and, probably, air pollution. Although diversely impacted or reported, many parts of Europe suffered human and other losses, such as farming and forestry through drought and fires. Summer 2003 was the hottest in Europe since 1500, very likely due in part to anthropogenic climate change. The French experience confirms research establishing that heat waves are a major mortal risk, number one among so-called natural hazards in postindustrial societies. Yet France had no policy in place, as if dangerous climate were restricted to a distant or uncertain future of climate change, or to preindustrial countries. We analyze the heat wave's profile as a strongly attenuated risk in the French context, as well as the causes and the effects of its sudden shift into amplification. Research and preparedness needs are highlighted. 相似文献

Chinese version of the OSI: A validation study 总被引:5,自引:0,他引:5
Luo Lu Cary L. Cooper Yen Ching Chen Chia Ho Hsu Hung Luan Wu Jian Bin Shih Chi Hua Li 《Work and stress》1997,11(1):79-86
This article examines the construct validity of the Occupational Stress Indicator (OSI) in its Chinese version as well as its criterion-oriented validity against self-reported data on absenteeism and accidents, using a final sample of 1054 workers in the Chinese manufacturing and power industries. The divergent and convergent validities of five of the OSI scales—Job satisfaction, Physical ill-health, Mental ill-health, Type A behaviour and Control—were examined by a multimethod-multitrait matrix technique. Results indicated that the Chinese OSI had fairly good validity in relation to other well-established measures as well as relevant organizational behaviours. 相似文献

In this article, we consider an ergodic Ornstein–Uhlenbeck process with jumps driven by a Brownian motion and a compensated Poisson process, whose drift and diffusion coefficients as well as its jump intensity depend on unknown parameters. Considering the process discretely observed at high frequency, we derive the local asymptotic normality property. To obtain this result, Malliavin calculus and Girsanov’s theorem are applied to write the log-likelihood ratio in terms of sums of conditional expectations, for which a central limit theorem for triangular arrays can be applied. 相似文献

以FDI与我国出口贸易品技术含量的关系作为切入点,选择通信设备、计算机制造业、医药制造业作为高新技术产业的代表,通用设备制造业、专用设备制造业作为传统制造业的代表。根据这4个行业1997—2011年利用外资与出口贸易品技术含量的数据,基于面板数据模型对高新技术产业和传统制造业FDI与出口贸易品技术含量之间的长期均衡关系及相关性进行实证分析。结果表明:高新技术产业利用外资与出口贸易品技术含量存在着长期均衡稳定关系,出口贸易品技术含量随着高新技术产业利用外资的增加而提高,并有明显的促进作用,而传统制造业利用外资对出口贸易品技术含量的影响有限。 相似文献
