美国文学中的“美国梦”——美国戏剧、小说统计分析

在美国,人们普遍相信,只要通过不懈努力和辛勤劳作,上天总会眷顾他们而赐予他们财富和幸福,这便是＂美国梦＂。不同历史时期,＂美国梦＂的影响或大或小,或推动社会的进步,或遭舆论谴责质疑。文学,作为社会变更的直接反映,吸收＂美国梦＂这一主题并出现在小说、戏剧、影视作品中。追溯美国历史长河,漫游美国文学巨作,我们可以找到一条＂美国梦＂的兴衰轨迹,它与美国历史紧密相关。文章旨在收集殖民时期以来,美国文学作品中以＂美国梦＂为主题的小说、戏剧作品,统计他们在全美文学同类作品中所占的比例,以图表的方式呈现,针对各个时期的不同特征,分析文学作品与社会因素的关联性。结果表明,文学作品与社会因素的联系是显而易见的。相关变化趋势亦预示着,随着新时代的到来,新秩序的建立,＂美国梦＂必将重新主导美国大众主流思潮,再度成为文学界的关注重点。

Bowling ball dynamics revealed by miniature wireless MEMS inertial measurement unit

This paper presents a novel sensor technology to deduce the dynamics of a bowling ball. The sensor, a miniature wireless inertial measurement unit (IMU), incorporates MEMS accelerometers and angular rate gyros, a microcontroller, a low power RF transceiver, and a rechargeable battery. When embedded in a bowling ball, the IMU transmits the acceleration and angular velocity data that define the dynamics of the ball starting with the bowler’s delivery and its motion in the lane. Example results from professional bowlers illustrate how this technology can be used to assess bowler skill and ball performance. For instance, the IMU accurately measures the spin dynamics of the ball which are crucial to develop the ball “hook.” An analysis of ball dynamics in the lane is distilled to a measurable “hook potential” metric for further assessing bowler skill. Finally, the sensor presented herein is believed to be the world’s smallest, wireless IMU. This highly miniaturized and wireless design will enable parallel training systems for many sports, including basketball, baseball, crew, cricket, golf, fly fishing, soccer, softball, tennis, rowing, among others.     

浅析方言地区普通话教学

在当前大力推广普通话的前提下,方言地区的学生面临着学习普通话中的一个硬伤:方言。方言给交际带来不便,为了克服方言给交际带来的隔阂,就要有沟通各种方言的共同语言存在。因此推广普通话应是一项长期而深入的工作。文章将从方言地区学生学习普通话的现状入手,从而找出一些普通话教学的方法与对策。

我国应制定公共部门信息资源增值利用法

政府行政机关在履行职责过程中制作、累积了海量的信息资源.随着<政府信息公开条例>的实行,政府制作或者获取的信息将向社会公开.对这些信息资源进行增值利用具有重要的社会意义与经济意义,也是政府信息功能的重要延伸.法律保障是建立信息资源增值利用制度的关键.我们需要制定一部<信息资源增值利用法>,对信息资源增值利用的程序、保障与监督、救济、法律责任等进行规范,以促进我国信息资源开发利用,促进信息资源产业的发展.

Effect of Vitamin E on sP-Selectin Levels in Pre-Eclampsia

P-selectin, a cell adhesion molecule is elevated in many inflammatory conditions including preeclampsia which is characterized by generalized endothelial dysfunction and vasoconstriction presumably due to free radicals or mediators released by defective placentation. Vitamin E has been documented to protect cell membranes from oxidative damage and also decrease platelet aggregation. The role of vitamin E in pre-eclampsia is contradictory and hence the study was undertaken. Soluble P-selectin was measured by ELISA and Vitamin-E levels in plasma was estimated spectrofluorometrically. In our study the effect of supplementation of 400 IU/day of Vitamin E (a-tocopheryl acetate) to patients of pre-eclampsia showed significant decreased levels of soluble P-selectin by 2nd week as compared to patients given placebo (P = 0.005). In this short period of study no direct correlations were observed between Vitamin E or P-selectin levels with blood pressure as well as with proteinuria. Future studies may focus on the effect of a-tocopheryl acetate or the phosphate form of Vitamin-E, recently proposed to be the more active form on other inflammatory markers like IL-6, an important stimuli of P-selectin release in pre-eclampsia.     

Role of Plasma MMP 9 levels in the Pathogenesis of Chronic Pancreatitis

Pancreatic fibrosis is a key pathological feature in the etiology of chronic pancreatitis that leads to obliteration of exocrine and endocrine pancreatic tissues and its replacement by fibrous tissue resulting in clinical manifestations. Matrix metalloproteinase 9 is a member of the MMP family that is also known as gelatinase B, degrades type IV collagen of extracellular matrix and basal membrane. The present study is aimed at evaluating the clinical significance of plasma concentration of MMP-9 in chronic pancreatitis. The samples were obtained from 112 chronic pancreatitis patients and an equal number of age and sex matched healthy controls. MMP-9 levels were quantitatively measured by ELISA assay. Statistical analysis was applied to test the significance of results. The present study revealed a significant increase of plasma MMP 9 levels in chronic pancreatitis patients compared to control subjects. Elevated levels were also observed in all the patient groups compared to control subjects with regard to sex, age, addictions etc. MMP-9 degrades the type IV collagens in normal basement membrane, which in turn activates the pancreatic stellate cells which promote the development of pancreatitic fibrosis. Thus, elevated plasma levels of MMP-9 may act as a susceptibility factor for the development of chronic pancreatitis.
