Determining the application sequence of hand-written pen ink and printer toner lines has attracted significant interest in questioned document examination. This study uses coaxial light to determine line-crossing sequences, with intersections observed under a VSC600 forensic document workstation and a Leica M205A Stereo-microscope. Results show that reflected light at intersections and color contrast between intersections and nonintersections was observed when a hand-written ink line passes over a toner line, while a toner line passing over a written line appeared dull, with no color contrast. The procedure was tested under a range of conditions, such as types of writing pens and laser printers, the writer, and writing pressure, with the latter playing an important role in the evaluation. To validate the results, a 90% detection rate and 98% accuracy rate were achieved from 50 samples of blind testing, which is more effective than optical microscopy. 相似文献

- This study explores the relationship among identities, goals, and public relations practices of an activist organization through in‐depth interviews and document analysis. Findings suggest different levels of the participant organization's identity in communication with its different audiences. In playing its dual role (as a “public” to its target organizations and a “public communicator” to its own publics), the organization acts as an honest representative voice and a credible source of information to both parties, a process that requires a balance position compatible with its mission. Its public relations practices were found to be consistent with the identities it appropriates and the values it respects.

国际汉学中的"误读"是外国汉学家接触中国文化时不可避免的。"误读"作为一个批评术语,它的出现明显受到了20世纪西方科学主义与人本主义哲学思潮及相关文论的影响。"误读"理论为我们正确对待汉学家的"误读"提供了可借鉴的方法论意义:汉学家研究中国、"误读"中国的根本目的是要借对汉学的研究审视自身;同时,其他民族对中国的研究也不妨成为我们自识的"镜像"。 相似文献

Mortgage foreclosures hit Detroit, Michigan hard between 2005 and 2014, especially in what we define as strong neighborhoods; there, more than one third of homes experienced foreclosure. Before the crisis hit, these selected tracts had largely intact physical environments and higher owner occupancy, household income and property value than the citywide median. In some of them residents worked intensely to abate the neighborhood effects of mortgage foreclosures. This study examines those efforts’ effectiveness. We selected neighborhoods with the most extensive efforts, as measured, for instance, by creation of community-based plans and applications for grants, and we conducted interviews and field observations to examine those efforts. To assess strengthening of neighborhood housing markets, we applied a modified adjusted interrupted time-series approach to evaluate changes in prices as one measure of neighborhood change. We found that strong resident initiative supported by community development organizations and external assistance led to increased neighborhood housing prices, compared with comparable neighborhoods. However, when initiative, context, and support were weaker, community-based efforts could not prevent considerable decline. 相似文献

This research combines insights from resource dependence and institutional theories to examine the growth of Chinese nonprofit revenues. The authors propose the concept of embedded government control (EGC) to capture the complexity of the government–nonprofit relationship along two dimensions: government regulation of nonprofits’ public fund‐raising qualifications and the political embeddedness of nonprofits with the government. Using a data set of 2,159 Chinese philanthropic foundations for the period 2005–12, the authors test hypotheses about the implications of EGC for nonprofit revenues in China following two major external shocks: the Wenchuan earthquake in 2008 and the Guo Meimei scandal in 2011. The empirical analysis shows that EGC can help philanthropic foundations obtain more government subsidies, donations, and market revenues. However, external shocks may either strengthen or weaken the enabling role of EGC in helping foundations acquire relatively more donations. 相似文献

党的十八大报告中首次提出"建设学习型、服务型、创新型的马克思主义执政党",而且将这个党的建设总目标写入了新修改的党章。从党的建设总目标的历史探索轨迹和党的建设总布局的形成发展轨迹看,从对执政党建设的理论意义和现实意义看,要把中国共产党建设成为学习型、服务型、创新型的马克思主义执政党确实是一项全新的重大课题。"学习型、服务型、创新型"既是一个系统的价值整体,同时,在这个系统中,又必须凸显全心全意为人民服务的根本宗旨,紧紧围绕改进服务方式、提高服务质量来加强学习、开拓创新,惟其如此,才能真正体现马克思主义执政党作为实现、维护和发展人民群众利益的工具的本质。 相似文献
