构建资源环境与经济协调发展模式的必要性及途径探讨

促进资源环境与经济协调发展,是构建和谐社会的一个重要方面。随着城市化进程的加快,资源环境的破坏和污染的程度也不断加剧,资源环境作为经济发展的物质基础保障,其对经济进一步发展的约束性也逐渐增强,因而加强资源环境与经济协调发展的研究、探讨资源环境与经济协调发展的模式成为社会经济发展的必然要求。     

Differentiation of Antemortem and Postmortem Appendicular Fractures Using Magnetic Resonance Imaging Signal Intensity Changes in Bone and Soft Tissues,

Intraosseous T1-weighted (T1W) and short-tau inversion recovery (STIR) magnetic resonance imaging (MRI) signal intensity changes—so-called bone marrow edema—may be able to differentiate antemortem and postmortem fractures in human forensic imaging. The primary objective of this study was to investigate this hypothesis using an animal model. Three juvenile Landrace pigs were anesthetized and underwent MRI of both tibiae and both radii using a 1.5 T magnet. T1W, T2-weighted (T2W), STIR, and T2* sequences were included. Antemortem fractures were induced in both tibiae and postmortem fractures in both radii, and MRI was repeated. Two board-certified radiologists blinded to fracture group jointly evaluated the images for intraosseous and soft tissue signal intensity changes. Sensitivity (Se) and specificity (Sp) in identifying antemortem fractures were calculated based on intraosseous, soft tissue, and combined intraosseous and soft tissue signal intensity changes. Intraosseous and soft tissue signal intensity changes, when present, were hyperintense in all sequences. Intraosseous hyperintensity in T1W and T2W sequences yielded Sp of 100% for antemortem fractures. Regardless of sequence, soft tissue hyperintensity was comparatively more sensitive than intraosseous hyperintensity. Sensitivity for each sequence could be maximized by assessment of soft tissue and intraosseous hyperintense signals together; for the T1W sequence, such assessment optimized diagnostic utility yielding a Se of 100% and Sp of 83%. In summary, MRI—particularly the T1W sequence—can differentiate antemortem and postmortem fractures and may be a useful adjunct to the forensic analyses of fractures.     

Globalization is What We Make of It: Contemporary Globalization Theory and the Future Construction of Global Interconnection

There are four perennial questions that preoccupy globalization theory. For those who write about globalization, there is a constant attempt to discover what globalization is, when it may have started, what benefits and burdens it offers for global cohabitation and whether globalization is ultimately a good thing or a bad thing. The purpose of this article is to review several new works in contemporary globalization theory and to assess what new answers they offer to these questions. Through this examination it will be argued that although these recent works provide significant improvements to former discussions on globalization, they still tend to lack an obvious insight. Namely, they fail to highlight fully the fact that whatever globalization is, it is as important to think normatively about directing its future as it is to understand its past. In other words, globalization is entirely what we make of it, both in how we cognitively come to understand it, but also in how we decide to shape its future.     

Race, religion, and informed consent--lessons from social science.

That minority patients have not figured at all in the literature about informed consent is an egregious omission which this article begins to repair. Moreover, the article demonstrates that by addressing identifiable harms which informed consent law now causes to racial, religious, and ethnic minority patients, the law may also better address many of the concerns legal commentators have been discussing for years with only majority patients in mind. Ironically, the solution to the discrimination felt by the excluded members of society may turn out to provide the remedy for the informed consent doctrine as a whole.     

Hanging — A review

A study of 201 cases of death due to hanging, 95% being suicidal in nature and 5% being accidental; in addition there was one judicial hanging. The majority of deaths were in persons over 50 years of age, males predominating particularly in the 50 – 60 age group. In contrast to the Registrar General's annual returns for suicide which show a steady decrease over the past 20 years, deaths due to hanging have increased considerably, particularly in the last decade. This trend could be related to the dramatic fall in carbon monoxide poisoning and more circumspect prescribing of barbiturate drugs.     

零和世界、合作世界,抑或杂乱世界?——全球性挑战、供选择的未来,以及中美两国的关系

应邀参加这次美国研究所成立30周年的纪念仪式并发表讲话,我感到非常荣幸。31年前,我曾经和李慎之先生聊到过他想要创建美国研究所的想法,因此对这个由他发起创办的重要机构,我有着一种格外的亲切感。更巧的是,我得以在1981年美国研究所成立的时候最先访问中国。所以,30周年纪念对我个人而言,意义尤
