唯物史观的新视域——胡锦涛对唯物史观出发点和落脚点的新解读

马克思在<德意志意识形态>中把"现实的个人"视为唯物史观的前提或出发点;邓小平确立了人民既是价值主体又是评价主体,体现出价值主体和评价主体的一致性;"三个代表"重要思想反映了时代精神的精华,其出发点和落脚点就是实现和维护最广大人民的"根本利益";胡锦涛总书记通过"群众利益无小事"这一质朴的语言进一步解读了"三个代表"重要思想,在新时期对唯物史观的出发点和落脚点问题作出了新的阐释,丰富和发展了马克思的唯物史观.     

《林兰香》成书不早于乾隆中期考论

当下都把《林兰香》定位于清初小说,但是这些结论并没有进行严格的考证。《林兰香》第54回＂汾酒＂一词,经考证最早出现于乾隆二年（1737）,而从方志等文献记载看,＂汾酒＂成为名酒是在乾隆（1736—1795）中后期,而＂汾酒＂在小说中则出现更晚,小说中出现的＂香肠＂最早也出现于雍正朝。故可知《林兰香》成书不会早于乾隆中期,更不会成书于康熙朝。     

关于《归档文件整理规则》的实践探索

《归档文件整理规则》已实施多年,这是我国文书立卷改革的重大举措,是新形式下档案现代化管理的一项重要标准。《规则》将传统的以"卷"为单位的操作方法转变为以"件"为单位的操作方法,强化了档案的基础工作与计算机管理相结合,极大地促进了"办公一体化"进程。《规则》的重要作用和优越性随着档案信息化管理的发展更加凸现,同时引发其它类档案管理办法改革的思考。

模切机传纸机构驱动凸轮参数化设计

运用MATLAB强大的可视化编程功能,针对模切机传纸机构中的关键零件—凸轮进行了参数化设计计算,得到了驱动递纸牙按照规定的轨迹运动的2个凸轮轮廓轨迹曲线,并检验了凸轮压力角,以验证传纸机构的合理性。当需要进行机构的某方面调整时,可以利用修改凸轮个别参数从而非常方便的进行更新,大大提高了机构设计的调整适应性,提高了快速设计产品的进程。     

Comparative Risks of Cancer from Drywall Finishing Based on Stochastic Modeling of Cumulative Exposures to Respirable Dusts and Chrysotile Asbestos Fibers

Sanding joint compounds is a dusty activity and exposures are not well characterized. Until the mid 1970s, asbestos‐containing joint compounds were used by some people such that sanding could emit dust and asbestos fibers. We estimated the distribution of 8‐h TWA concentrations and cumulative exposures to respirable dusts and chrysotile asbestos fibers for four worker groups: (1) drywall specialists, (2) generalists, (3) tradespersons who are bystanders to drywall finishing, and (4) do‐it‐yourselfers (DIYers). Data collected through a survey of experienced contractors, direct field observations, and literature were used to develop prototypical exposure scenarios for each worker group. To these exposure scenarios, we applied a previously developed semi‐empirical mathematical model that predicts area as well as personal breathing zone respirable dust concentrations. An empirical factor was used to estimate chrysotile fiber concentrations from respirable dust concentrations. On a task basis, we found mean 8‐h TWA concentrations of respirable dust and chrysotile fibers are numerically highest for specialists, followed by generalists, DIYers, and bystander tradespersons; these concentrations are estimated to be in excess of the respective current but not historical Threshold Limit Values. Due to differences in frequency of activities, annual cumulative exposures are highest for specialists, followed by generalists, bystander tradespersons, and DIYers. Cumulative exposure estimates for chrysotile fibers from drywall finishing are expected to result in few, if any, mesothelioma or excess lung cancer deaths according to recently published risk assessments. Given the dustiness of drywall finishing, we recommend diligence in the use of readily available source controls.
