文化多样性与都市竞争力——国际化语境中的上海文化发展战略研究

文化是一个城市的竞争力和软实力的重要决定性因素,而文化多样性对于城市尤其是国际化大都市的持续发展来说意义重大,是国际化大都市持续发展的活力源泉和魅力体现。在比较和借鉴伦敦、纽约、香港等大都市的多样性文化战略的基础上,重点分析上海自身的文化优势、不足和潜力,求索方案和建议,以打造上海作为国际文化大都市的发展战略,同时前瞻性地反思在发展文化多样性中应注意的平衡关系。     

《诗·豳风·七月》研究

《诗豳风七月》作于早周公刘之世,其时在公元前十六世纪中叶,约当夏桀之世。这在《七月》的礼俗、社会状况、名物、艺术形式等方面均有所体现。《七月》作为早期周族诗历,通篇皆用周历记事。周历的“七月流火”正是夏代才有的天象,成为判断此诗作年的坚强证据。     

关于高校招标采购监管工作的调查研究

当前高校招标采购的运作方式大致可分为专职模式、兼职模式和分散模式。不少高校存在采购计划性不强、缺乏开展招标工作的专业条件、招标信息发布不广、审批程序不规范和监督不到位等问题。应加强基本条件建设,进一步理顺内部管理机制,加强监督和制约,以保证高校招标采购工作的健康发展。     

南宁与越南产业合作对策研究

南宁与越南产业合作是南宁与东盟诸国产业合作的起始、实验田、模板,是中国-东盟自由贸易区建设的重要途径探索。目前,南宁与越南产业合作渐具规模,但也存在诸多问题。为此,应采取多种措施进一步促进南宁与越南的产业合作。     

Buffers of Racial Discrimination: Links With Depression Among Rural African American Mothers

The current study examines racial discrimination as a predictor of depression in a sample of 414 rural, low‐income African American mothers of young children. The potential moderating role of optimism and church‐based social support was also examined. Mothers completed questionnaires when their child was 24 months old. Hierarchical regression revealed that mothers' perception of racism was a significant predictor of depression even after controlling for a variety of distal demographic characteristics and environmental stressors. Significant interactions suggested the importance of psychological and social characteristics in understanding maternal depression. Specifically, high levels of optimism and church‐based social support buffered mothers from increased depressive symptomology attributable to perceived racism.     

走生态文明建设康庄大道——争当生态文明建设排头兵战略与对策研究

生态文明是人们正确认识和处理人类社会与自然生态系统相互关系的理念、态度及生存和发展方式.建设生态文明新概念和新战略的提出把马克思主义生态文明理论与实践推进到了一个新阶段.在借鉴国外经验和分析国情省情的基础上,云南省要走生态文明建设道路,争当生态文明建设排头兵,必须确立和实施环境优先、生态立省,生态、经济、政治、社会、文化"五位一体"的发展战略,"十二五"经济社会发展规划应成为包括生态相对独立领域在内的"五位一体"全面协调可持续发展规划.     

Estimating the Causal Effect of Low Tidal Volume Ventilation on Survival in Patients with Acute Lung Injury

Acute lung injury (ALI) is a condition characterized by acute onset of severe hypoxemia and bilateral pulmonary infiltrates. ALI patients typically require mechanical ventilation in an intensive care unit. Low tidal volume ventilation (LTVV), a time-varying dynamic treatment regime, has been recommended as an effective ventilation strategy. This recommendation was based on the results of the ARMA study, a randomized clinical trial designed to compare low vs. high tidal volume strategies (The Acute Respiratory Distress Syndrome Network, 2000) . After publication of the trial, some critics focused on the high non-adherence rates in the LTVV arm suggesting that non-adherence occurred because treating physicians felt that deviating from the prescribed regime would improve patient outcomes. In this paper, we seek to address this controversy by estimating the survival distribution in the counterfactual setting where all patients assigned to LTVV followed the regime. Inference is based on a fully Bayesian implementation of Robins' (1986) G-computation formula. In addition to re-analyzing data from the ARMA trial, we also apply our methodology to data from a subsequent trial (ALVEOLI), which implemented the LTVV regime in both of its study arms and also suffered from non-adherence.     

慢性阻塞性肺疾病患者肺通气功能检查结果分析

目的探讨肺功能检测中通气各项指标在高龄慢性阻塞性肺疾病（COPD）诊断及病情评估中的意义。方法对我科2007年11月至2008年11月200例70岁以上COPD患者肺功能检查中通气指标进行回顾性分析．并使用SPSS13．0软件对肺功能各项指标进行分析。结果COPD轻、中、重、极重度患者的FEV1、FVC、FEV1／FVC、PEF、MMEF、V50V25MVV与正常对照组均有下降（P〈0．001）;COPD各个组间FEV1均有统计学差异（P〈0．001）;COPD轻度患者的MMEF、V50、V25与正常对照组相比即有明显下降（P〈0．001）;中度、重度及极重度COPD患者的VC与其他各组相比有明显下降（P〈0．001）;各组MVV、PEF与FEV,均有高度正相关性。结论肺通气功能检查是诊断COPD的金标准,MMEF、V50、V25为检测早期COPD患者的敏感指标;FEV1、PEF、MVV均是反映COPD气流阻塞程度的指标。
