突破边界——评彼得-保罗·维贝克的《将技术道德化:物之道德的理解与设计》

彼得-保罗·维贝克的著作《将技术道德化》,是现代技术哲学史上伦理转向的开端。该书揭示了存在于道德和技术人工物相互作用领域中的两个维度:新技术的应用带来了新的伦理问题,以及用经过专门设计的技术来改变人的道德行为。维贝克借此所提出的是一种物质化的伦理学观点。在与行动主体相互结合、相互构成的意义上,各种技术产品对道德抉择及行动也具有影响力,进而技术设计者可以被认为是"实践的伦理学家"。同时,对维贝克为实现技术民主而提出的"建构性的技术评价"进行了商榷。《将技术道德化》为技术哲学中经验转向和伦理转向的融合,做出了有益的尝试。     

朱子美学视域下的闽北古民居审美文化研究--以武夷山古民居为例

闽北古民居建筑肃穆质朴、英华内敛,其独特的审美风格深受闽学骨干--朱熹理学美学思想的影响。其中影响最为深刻、直接的是“文从道出”的装饰理念,“托物言辞”的造物手法和“气象浑成”的艺术理想。本文结合武夷山古民居的装饰、布局、色彩实例,分别对以上三方面影响进行了诠释,以探索闽北古民居这一民族历史文化遗产的美学意义。     

Improving teacher preparation and selection: lessons from the Pennsylvania experience

This paper examines Pennsylvania's teacher preparation and selection processes over the last decade. Teacher test scores are examined across colleges of education, and extreme differences in teacher test scores are found. Also, extreme variations are evident among districts' employed teachers. A unique survey of district employment practices reveals that, on average, 40% of a district's teachers previously attended there as students. An exploratory econometric model indicates that the higher the unemployment rate in a district, the more likely it will hire its former students to teach, and that the greater the fraction of former students now in the district's teacher force, the lower is student achievement. The paper concludes with a discussion of conventional and unconventional strategies to improve the quality of teachers actually hired by school boards.     

Rethinking Mobile Delivery: Using Quick Response Codes to Access Information at the Point of Need

This article covers the use of Quick Response (QR) codes to provide instant mobile access to information, digital collections, educational offerings, library website, subject guides, text messages, videos, and library personnel. The array of uses and the value of using QR codes to push customized information to patrons are explained. A case is developed for using QR codes for mobile delivery of customized information to patrons. Applications in use at the Libraries of the University of Utah will be reviewed to provide readers with ideas for use in their library.

基于变长Turbo码的低复杂度联合信源信道译码

基于变长Turbo码的联合信源信道译码通过构造联合译码平面网格图,具有比比特级译码更好的性能.但平面网格图复杂,使变长Turbo码译码复杂度高.基于此,构造了一个空间网格图,提出基于变长Turbo码的低复杂度联合信源信道译码方法.仿真结果表明,该算法比平面网格图计算复杂度减少约3.8%,在SER(symbol error ratio)为10-4时,获得Eb/N0增益约为0.2dB.

本文主要讨论了环Zp+uZp+u2Zp(u3=0,p为奇素数)上自对偶码,通过环Zp上的对偶码得出环Zp+uZp+u2Zp上自对偶码的个数。     

Tracking the History of Romani Publications: Challenges Presented by Flawed Data

Romani is a language of northern Indic origin spoken natively by an estimated 2.5 million people, primarily in Eurasia but also in North America. The history of publication patterns in Romani has not been well documented. Extracting data about this history based on available information in large bibliographic databases such as OCLC WorldCat has been hampered by unfortunate misapplication of certain language codes, making it all but impossible to filter search results efficiently using Romani language as a parameter. The author discusses how he was able to correct much of this inaccurate data in OCLC WorldCat.     

Writing for Publication and the Role of the Library: “Do Have a Cow,Man!” (“Don't Have a Cow,Man”-Bart Simpson)

The aim of this small-scale research project was to identify the main concerns of editors, academics, researchers, and librarians involved in the writing for publication (WfP) process. This would provide library and information services (LIS) staff with a clearer understanding of the process to enable them to articulate and develop their own role in supporting this activity. A novel “one thing” approach was used to determine the perspectives of editors, researchers, librarians, and research students on key issues surrounding WfP. The results indicate that there are many opportunities for LIS staff to contribute to the WfP process. One major concern which emerged was just how isolated researchers could feel. Suggestion: Having a CoW (Community of Writers) in the library could provide a potential LIS role. Another best practice to support WfP is also identified.
