Literary Studies: A Preparation for Tertiary Education (and Life Beyond)

My argument is that a literary education should build on a primary level of responsivity towards literature, involving empathy and immersion in the world of the text. To engage with literary works from the past involves a play between familiarity and strangeness, and this play should be located as part of a reader’s response to texts, rather than expecting students to imbibe the ‘dead knowledge’ about literary periods and authors in which textbooks and literary guides traffic. Literary responsiveness involves sensitivity towards the specific character of the text, which means locating it in relation to other texts belonging to that genre without reducing it to being merely illustrative of a genre’s so-called characteristics. In all these respects, contemporary educational standards reflect questionable assumptions about the development of a capacity to respond to literary texts, especially the supposition that a ‘mature’ response to literature somehow involves moving beyond personal response to more analytical forms of engagement.

生产力标准新探

探讨生产力标准应从多维度、多层次进行，既要坚持唯物主义原则，又要运用辩证法方法。文章指出：生产力标准既是真理标准又是价值标准，既具有一元性又具有多样性，是真理与价值、一元性与多样性的统一。生产力标准的多维性要求我们既要重视自然生产力，也要重视社会生产力；既要重视物质生产力，也要重视精神生产力和人才生产力；同时还要处理好它们之间的关系。

Modeling data quality for risk assessment of GIS

This paper presents a methodology to determine three data quality (DQ) risk characteristics: accuracy, comprehensiveness and nonmembership. The methodology provides a set of quantitative models to confirm the information quality risks for the database of the geographical information system (GIS). Four quantitative measures are introduced to examine how the quality risks of source information affect the quality of information outputs produced using the relational algebra operations Selection, Projection, and Cubic Product. It can be used to determine how quality risks associated with diverse data sources affect the derived data. The GIS is the prime source of information on the location of cables, and detection time strongly depends on whether maps indicate the presence of cables in the construction business. Poor data quality in the GIS can contribute to increased risk or higher risk avoidance costs. A case study provides a numerical example of the calculation of the trade-offs between risk and detection costs and provides an example of the calculation of the costs of data quality. We conclude that the model contributes valuable new insight.     

对归化和异化之争的再思考

翻译中有两种不同策略——归化和异化,它们在不同的时期、不同的场合各有其用,到底是归化还是异化,要遵循以读者的反应来检验其效果的原则。     

基于可靠性的平面凸轮机构的弹性动力学响应

将可靠性的理论用于平面凸轮机构的弹性动力学分析中，首先建立平面凸轮机构的弹性动力学分析模型，推导出基于可靠性的平面凸轮机构的弹性动力学响应的公式，并将这些公式应用于平面凸轮机构的弹性动力学分析的算例中，认为其在设计平面凸轮机构时具有指导性意义，这对高速机构的研究有着重要的理论和实际意义。
