This article explains the position(s) of the United States in the maritime dispute adjacent to Svalbard. While the United States has regarded Norway's exclusive claim to the natural resources outside Svalbard as everything from “wishful thinking” to legally plausible, Washington maintains that it may have rights under the 1920 Svalbard Treaty to exploit the maritime zones adjacent to the archipelago. The U.S. reservation is the result of assessments and reassessments of legal considerations as well as national interests.  相似文献

The issue of the status of the Northwest Passage has ebbed and flowed in U.S.-Canada relations for decades, but the effect of global warming in the Arctic has moved this issue from the largely academic and legalistic realms to the forefront of bilateral (and international) relations. Intimately linked to Canadian nationalism, U.S. adherence to the doctrine of freedom of the seas, and to politics in both nations, the opposing positions held by the two states can no longer afford to be implacably held. Rather, it is time to put pride and politics aside and return to the “special relationship” between Canada and the United States in order to effect meaningful and mutually beneficial continental security.  相似文献

The United States is the sole superpower in the contemporary world and its role in the development of the law of the sea cannot be ignored. Although having not yet acceded to the U.N. Convention on the Law of the Sea, the United States has contributed to the development of the international law of the sea in numerous ways, including responding to the so-called excessive maritime claims in East Asia and creating new rules of maritime enforcement. This article assesses this recent U.S. practice.  相似文献

I respond to a review by C. Matthew Snipp, revisiting how my book connects abolitionist leanings to acceptance of racial mixing in the Early Republic. I reiterate that, contrary to the reviewer's claims, the book does not suggest that the defence of interracial marriage has been a thriving social movement. I correct his reading of my chapter on the Civil War era, referring to both the variety of voices present, and the claims of reformers' opponents, who were the only ones who claimed racial mixing was an aim of the abolitionist movement. Lastly, I defend The United States of the United Races against Professor Snipp's characterization of it as a work anticipating a ‘post-racial’ ideal, embodied by racially mixed people, who would be the end point of the obsolescence of race as a relevant analytic tool.  相似文献

Background

Recent studies have emphasized the role of psychosocial stressors as a determinant of asthma, and neighborhoods can be a potential source of such stressors. We investigated the association between parental perception of neighborhood safety and reported lifetime asthma among children.

Methodology/Principal Findings

Data for the study came from the 2003–04 National Survey of Children Health (NSCH); a nationally representative cross-sectional sample of children aged 0–17 years. Demographic, socioeconomic and behavioral covariates were included in the study. Models were estimated after taking account of weighting and complex survey design. Parental report of whether the child has ever been diagnosed with asthma by a physician was used to define the outcome. Parental report of perception of neighborhood safety was the main exposure. In unadjusted models, the odds ratio (OR) for reporting asthma associated with living in neighborhoods that were perceived to be sometimes or never safe was 1.36 (95% confidence intervals [CI] 1.21, 1.53) compared to living in neighborhoods that were perceived to be always safe. Adjusting for covariates including exposure to second hand tobacco smoke, mother''s self-rated health, child''s physical activity and television viewing attenuated this association (OR 1.25, 95% CI 1.08, 1.43). In adjusted models, the increased odds ratio for reporting asthma was also higher among those who perceived neighborhoods as being usually safe (OR 1.15 95% CI 1.06, 1.26), as compared to always safe, suggestive of a dose-response relationship, with the differentials for usually safe and never safe being statistically significant (p = 0.009).

Conclusion

Psychosocial stressors may be important risk factors that may impact the pathogenesis of asthma and/or contribute to asthma morbidity by triggering exacerbations through neuroimmunologic mechanisms, as well as social mechanisms.  相似文献

Cow's milk is accorded a high cultural value in the contemporary United States. Its white color, association with the maternal and the pastoral, and repeated mention in the Bible add positive symbolic weight to this major national agricultural commodity. Thus, it comes as no surprise that influential policy-making institutions in the United States recommend milk consumption for all U.S. groups. This is despite variation in adult populations' abilities to digest milk, which has been documented by biological anthropologists. This article assesses various U.S. "stories" about milk consumption and its relationship to biological variation against the biological anthropological explanation of variation in lactase activity/lactose tolerance. Many of these serve as normalizing discourses that ultimately pathologize biological difference and may undermine the dietary traditions of some ethnic groups. In particular, the close relationship between government and the dairy industry leads to policies that fail to seriously consider variation in digestive physiology among the diverse U.S. populations.  相似文献

Ataxia-telangiectasia (A-T) is an autosomal recessive neurological syndrome of considerable interest because homozygotes are highly predisposed to cancer. Vigorous casefinding in the United States in 1970-72 and 1980-84 identified 231 white, 29 black, and three Oriental A-T cases that provide information about the incidence and gene frequency of A-T. White patients identified in this study were born at the rate of 3.0 per million live births in the U.S. in the years 1965-69. The highest observed incidence was in the state of Michigan for 1965-69, where identified white A-T patients were born at the rate of 11.3 per million births. Based on the incidence data, the minimum frequency of a single hypothetical A-T gene in the U.S. white population was estimated to be .0017. Pedigree analysis, which estimates the gene frequency from the proportion of affected close blood relatives of homozygous probands, estimated the most likely gene frequency to be .007 on the assumption that A-T is a single homogeneous genetic syndrome, with 95% confidence limits of .0012-.02. Given that complementation analysis has demonstrated the genetic heterogeneity of A-T, the A-T heterozygote frequency will probably fall between 0.68% and 7.7%, with 2.8% being the most likely estimate.  相似文献

There is increasing national recognition that while our nation''s health care system is the most expensive in the world, the health care status of Americans overall ranks poorly compared with other Western, industrialized nations. In the United States we tend to look at minority-majority variations of health status, as well as the variations of many other indicators by race or ethnicity, because race and ethnicity are particularly important components of our society. In general, health status indicators of minority Americans are worse than those of whites. In some locales, death rates of minority Americans are comparable to those of Third World nations. At the same time, minority Americans make up a rapidly increasing proportion of the nation''s population and work force. Our baseline national data on some minority groups, however, currently are inadequate to detect shifts in health status. Finally, the rapidly expanding problem of the acquired immunodeficiency syndrome among some minority populations provides both an imperative and an opportunity to learn how model prevention programs should be designed and executed.  相似文献
