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.     

城市外来农民工街头非正规就业现象浅析

以做散工的方式就业,即非正规就业,是当前农民工在城市获取就业机会的一种重要方式.街头非正规就业以其容易进入、较少受到管制而得到一些农民工的欢迎.本文以在福州城区的实证调查为基础,分析了街头做散工的农民工群体的特征,指出农民工街头非正规就业实际上是他们一种不得已的选择.     

经济学的道德科学回归——兼论美国金融危机的深层原因

从亚当·斯密到凯恩斯,经济学始终是一门道德的科学,而新自由主义的效率中心导向把经济学引向一个类似于自然科学的领域,并使其逐渐上升为美国主流的政策过程.一种投机的、掠夺的资本积累方式,新自由主义实现了依存于美国的国际资金回流.经济学的道德科学回归是走出金融危机的根本路径.     

网络文化的意识形态渗透及其应对

游戏主义的滋生与网络游戏的流行有关.新自由主义在网络文化的喧嚣中被放大.技术主义源自于对信息技术的崇拜.全球主义借助全球网络化而泛滥.在宽松的网络环境下,这些非主流或反主流的网络文化渐渐汇聚成流,表达情绪、传播观点,一点一滴地改变着网络意识,形成对主流意识形态的分进舍围.巩固党的意识形态领导权,根本的是要提升主流意识形态在网络冲突中的自卫能力,这就要求它集中网络智慧,转向网络话语,关注网络心理,改进网络创作方式、包装方式和扩散方式,强化自身的渗透功能.     

西方发达国家社会建设的经验

进行社会建设是所有国家在现代化进程中的共性问题,在这方面,西方国家已经取得了一定的经验。首先是以自由、民主、人权为核心的主流价值观念及其外化的制度为西方社会建设提供了精神动力和制度支持;其次是强大的教育体系和人才吸引政策为西方社会建设提供了最重要的生产力因素,确保了社会的合理有序的流动;再次是一系列利益均衡和矛盾化解机制,促进了社会阶层的沟通,规避了社会风险;最后完善的社会保障体系,确保了社会利益结构中最不利人群的利益,避免了社会底层的“沉淀”和“固化”,弥合了社会断层和分裂。虽然各国的社会制度不同甚至相互对立,但是,在社会建设的体制、机制的具体环节上存在着一些“中性范畴”,主动借鉴和吸取他国的经验和做法,准确把握和谐社会建设的共同规律,有益于我国社会主义和谐社会的建设。     

认真学习深刻领会全面准确地把握十六大的基本精神

党的十六大精神非常重要、非常深刻、非常丰富。会议的重要神集中体现在江泽民同志的报告中,要认真学习,深刻领会,准把握报告的精神实质。一是要深刻理解大会的主题。党的十六大的主题是:“高举邓平理论伟大旗帜,全面贯彻‘三个代表’重要思想,继往开来,与俱进,全面建设小康社会,加快推进社会主义现代化,为开创中特色社会主义事业新局面而奋斗”。这一主题,顺应时代要求,合党心民心,鲜明地向世人昭示:在新世纪新阶段,中国共产党举的旗帜,就是马克思列宁主义、毛泽东思想、邓小平理论的旗,就是“三个代表”重要思想的旗帜;中国共产党要走的道…     

罪犯身体健康权的缺损与救济

罪犯权利有应有权利、法定权利和实有权利之分。身体健康权是罪犯的应有权利和法定权利。但在实践中,罪犯的身体健康权存在着种种缺损。罪犯的身体健康权的缺损应通过刑罚处罚、行政处分、民事损害赔偿和刑事赔偿等主要手段予以救济。

文化多元化进程中大学生道德人格的嬗变及其应对

当代中国,异质、开放、无政府的网络文化导致大学生的道德人格变异,商业化、标准化、通俗化的大众文化导致大学生的道德人格偏移,物欲泛滥、个性张扬、追求世俗的消费文化导致大学生的道德理性危机。大学道德教育应当预见并思考新的文化景观,建构网络教育与生活教育、实践教育与理论教育之间的联系,倡导全面、开放的教育方式,培育大学生健全的网络道德人格、日常道德人格和社会道德人格,使道德教育真正深入大学生的生活,触动大学生的心灵,发挥育人的功效。
