An integrated process control (IPC) procedure is a scheme which combines the engineering process control (EPC) and the statistical process control (SPC) procedures for the process where the noise and a special cause are present. The most efficient way of reducing the effect of the noise is to adjust the process by its forecast, which is done by the EPC procedure. The special cause, which produces significant deviations of the process level from the target, can be detected by the monitoring scheme, which is done by the SPC procedure. The effects of special causes can be eliminated by a rectifying action. The performance of the IPC procedure is evaluated in terms of the average run length (ARL) or the expected cost per unit time (ECU). In designing the IPC procedure for practical use, it is essential to derive its properties constituting the ARL or ECU based on the proposed process model. The process is usually assumed as it starts only with noise, and special causes occur at random times afterwards. The special cause is assumed to change the mean as well as all the parameters of the in-control model. The linear filter models for the process level as well as the controller and the observed deviations for the IPC procedure are developed here. 相似文献

This study analyses weblog abortion-related content sampled via a search and snowball method. When weblogs located inside of established media Web sites and other weblogs are compared, they are equivalent in the use of advocacy versus objectivist frames. Media weblog posts contain a political frame more frequently than non-media weblog posts do. In terms of diversity of frame, media weblogs employ more frames in their stories. Various explanations for these findings are offered in the context of current abortion-related content patterns. 相似文献

This article examines the interplay of homophily (similarity breeds connection) at two levels in international trade—dyadic similarity (geographic, political, and cultural proximity) and systemic similarity (structural equivalence and world‐system status). First, there is a substitution effect between dyadic homophily and systemic homophily from structural equivalence. Both types of homophily generate favorable social structure that facilitates international trade. The existence of structural equivalence lessens the dependence of bilateral trade on dyadic homophily. Second, there is a stratification effect of world‐system status on dyadic homophily. Geographic homophily matters the most for bilateral trade between two noncore countries, while political and cultural homophily is the most influential for trade between a core country and a noncore country. These two findings have important implications. The substitution effect of structural equivalence prevents international trade from complete fragmentation along geographic, political, and cultural lines, while the stratification effect of world‐system status reveals unequal capacity across countries to overcome the structural constraints imposed by dyadic homophily. 相似文献

Most Racial Studies primarily focus on African Americans without paying attention to nonblack minorities, and it fails to capture recent increase in racial diversity. Based on previous theories and empirical findings, we propose a new model, minority comparison model, which accounts for theoretical shortcomings in Racial Studies. This model (1) captures psychological processes that compare blacks and nonblacks, and (2) explores the effects of whites’ multiracial evaluation on racialized policy preferences. Drawing on a 2008 national representative sample, this study finds that whites who have positive stereotype of nonblacks (e.g., Hispanics and/or Asians) but negative stereotype of blacks show substantially higher symbolic racism and stronger opposition to Affirmative Action, whereas whites who have positive stereotype of blacks but negative stereotypes of nonblacks have stronger opposition to expansive immigration policy. Our study offers new ways of understanding and accounting for symbolic racism in modern context, and shows how whites’ preferences in racialized policies are influenced by multiracial evaluation. 相似文献

2009年12月26日通过的《侵权责任法》明确规定在同一事故中可不考虑个人差异,以同一数额确定死亡赔偿金。该条同命同价条款引起社会各界的广泛关注。死亡赔偿并不是对死者生命价值的赔偿,而是对死者近亲属受损利益的救济。死亡赔偿从扶养丧失说改采继承丧失说,赔偿标准采定型化赔偿和客观计算,体现了立法没有为了逻辑自治而漠视社会现实,但对城乡居民采用了两分法的计算标准,显然违背了死亡赔偿金设立的初衷。今后死亡赔偿金制度的完善必然取决于对有关利弊的实证分析而非抽象的逻辑推理。 相似文献

从易心莹的求学经历看,儒学构成了其知识结构非常重要的一部分,故他才会采用<三字经>的形式来宣传道教知识.可以说,<道教三字经>是易心莹援儒人道的具体表现,易心莹虽身为道士,但其内心"笃守儒师与道家学理"却是一个不能忽略的事实. 相似文献
