解读人与自然的和谐

人与自然和谐包含着丰富和深刻的内涵 ,从理论层面上看 ,它应是人与自然互相适应的辩证统一 ;从实践层面上讲 ,它应是人与自然双方均处于既被改造又应保护的关系之中。必须反对在这个问题上的各种片面的观点与看法

自我·故我·他人——谈索尔·贝娄的人物塑造

索尔·贝娄以“对人类文化富于人性的理解和精妙的分析”获得诺贝尔文学奖,这种理解和分析在人物塑造上则表现为对人的完整认识和对人性的深刻分析。在他的作品中,贝娄将人物的自我作为叙述的中心,在自我、故我与他人的对立统一中塑造自我。本文结合当代哲学的相关理论具体探讨贝娄的人物塑造,和其表现出的对人的本质的深刻理解。     

Media Technologies, Images of Drugs, and an Evocative Telepresence

I regard electronic media technologies as framing devices for how viewers perceive issues associated with illegal drugs. Controllers of electronic media technologies produce and disseminate images of illegal drugs and users of such drugs to which viewers respond. People who control the images of electronic media production create an evocative telepresence, or a visual context that relies on appeals to authority and emotion. However, viewers do not merely respond to images of illegal drugs; rather, they actively interpret such images and draw their own conclusions. To demonstrate the complex relationship between electronic stimuli and viewer responses, I report on a classroom experiment comparing those who saw and heard a heroin user with those who only heard this user. I also report findings from student perceptions of and reactions to four drug films. Results of the experiment and the readings of films indicate that viewers, especially those who can see and hear electronic displays, are sophisticated consumers who respond to immediate stimuli while making reference to distal stimuli. In the main, I contend that electronic images of illegal drugs and users in an evocative telepresence are powerful stimuli, but they do not cause viewer perceptions.     

后殖民主义视角下的《地之国》解读

约瑟夫·奥尼尔的《地之国》被认为是近年来最出色的表现"9.11事件"后美国的作品之一,但字里行间表现出的后殖民主义特征才是其最引人瞩目之处。小说以回忆录的方式记叙了两个不同肤色、不同阶层的男人在美国的境遇和友谊。本文试图从后殖民主义理论出发,从移民的美国梦想、身份建构和文化认同几个方面阐释作品的深刻内涵,探索众多移民在西方文化中心论依旧盛行的今天,在全球化的时代获得物质和精神双重满足的途径。     

一种应用于药品泡罩包装检测的改进分水岭算法研究

针对分水岭算法存在的过分割问题以及泡罩包装药品图像的特点,提出一种改进的分水岭分割算法对泡罩包装的药品进行分割。该方法将形态学重建运算与使用控制标记符的方法相结合,首先对原图像进行开闭重建,根据邻域像素连通性提取重建后图像的局部极大值作为标记,从而抑制其他的局部极小值,然后依据标记对原始的梯度图像进行修正,最后对修改后的梯度图像进行分水岭分割。试验表明,该方法在缺陷药品检测中,可以有效的抑制传统分水岭的过分割,分割效果良好。     

社会工作专业教学组织机制：问题与选择

优化教学组织机制是提高社会工作专业教育质量不可或缺的重要一环。面对社会工作专业课堂教学和实践教学他组织与自组织相分离的现实困境,教师要科学选择介入策略,勇于革新教学方法,以实现教学组织机制的优化。     

上海外来白领生存压力与社会信心调查

上海外来白领生存压力与社会信心调查显示,外来白领对上海整体较为满意,对上海的社会信心较高,同时在工作生活中也面临住房、健康、经济收支、身份认同等四大突出压力。上海应积极出台有效政策措施,努力疏解当前上海外来白领工作生活中的突出压力。     

孙中山的人学思想及其现实意义

孙中山的人学思想产生于19世纪末20世纪初的近代中国,是在其"致力国民革命四十年,求中国之自由平等"的斗争实践中逐渐形成的。它内涵丰富、意蕴深远,涉及互助人性论、民生观、自由平等观、"生元"说以及人生观等方面的内容。探讨发掘孙中山的人学思想中蕴含的积极合理成分,在当代无疑具有重要的现实意义。     

Testing for bioequivalence of highly variable drugs from TR‐RT crossover designs with heterogeneous residual variances

Traditional bioavailability studies assess average bioequivalence (ABE) between the test (T) and reference (R) products under the crossover design with TR and RT sequences. With highly variable (HV) drugs whose intrasubject coefficient of variation in pharmacokinetic measures is 30% or greater, assertion of ABE becomes difficult due to the large sample sizes needed to achieve adequate power. In 2011, the FDA adopted a more relaxed, yet complex, ABE criterion and supplied a procedure to assess this criterion exclusively under TRR‐RTR‐RRT and TRTR‐RTRT designs. However, designs with more than 2 periods are not always feasible. This present work investigates how to evaluate HV drugs under TR‐RT designs. A mixed model with heterogeneous residual variances is used to fit data from TR‐RT designs. Under the assumption of zero subject‐by‐formulation interaction, this basic model is comparable to the FDA‐recommended model for TRR‐RTR‐RRT and TRTR‐RTRT designs, suggesting the conceptual plausibility of our approach. To overcome the distributional dependency among summary statistics of model parameters, we develop statistical tests via the generalized pivotal quantity (GPQ). A real‐world data example is given to illustrate the utility of the resulting procedures. Our simulation study identifies a GPQ‐based testing procedure that evaluates HV drugs under practical TR‐RT designs with desirable type I error rate and reasonable power. In comparison to the FDA's approach, this GPQ‐based procedure gives similar performance when the product's intersubject standard deviation is low (≤0.4) and is most useful when practical considerations restrict the crossover design to 2 periods.
