现代科技革命的方法论转变

哥白尼、牛顿、达尔文在科学领域的革命促成了近代的世界观、方法论从神学向科学的转变 ,动力与传播革命改变了人的活动方式。现代科学的相对论和量子力学革命是走出牛顿科学的开端 ,计算机网络造成的信息社会提出了新的问题。现代科学的方法论思想重点在于强调时间的不可逆性、未来的不确定性和系统的自组织性。     

The use of GIS in informal settlement upgrading: its role and impact on the community and on local government

The Urban Geographical Information Systems (GIS) Group within the Department of Civil Engineering at the University of Cape Town has been coordinating a pilot informal settlement upgrading in Cape Town since 1998. The project objective has been the evolution of a model-based approach to informal settlement upgrading that is both structured and replicable. It was felt that the only way this could be achieved was through the use of a spatial data management system operated through a GIS system. The spatial database has been used for all facets of data collection and data process and forms the basis for all decision-making. Thus it covers all physical data pertaining to the site, cadastral and shack data, demographic and socio-economic data (with an in-depth review of every household) economic opportunities and physical planning and design data. The result is a comprehensive, integrated, settlement upgrading methodology that is built upon a GIS-based spatial data management framework. Such a framework is seen as the basic building block for large-scale informal settlement upgrading.     

几组复合麻醉方法对犬麻醉效果比较

复方846、静松灵/氯胺酮、氯丙嗪/氯胺酮、氯丙嗪/乙醚、氯丙嗪/静松灵,均可使犬获得一定时间的麻醉效果。通过麻醉前、后体温(T℃)、呼吸(R),脉搏(P),镇痛反应,麻醉维持时间的检测;通过麻醉后手术安静顺利情况;从伤口愈合情况,以及术前、术后3天、7天白细胞、淋巴细胞、T淋巴细胞的变化表明:几组药物作用于犬后,体温间差异不显著(P>0.05),呼吸、脉搏部分呈显著性变化(P>0.05),各组术前、术后3天、7天的白细胞、淋巴细胞、T淋巴细胞变化组间差异不显著(P>0.05)。镇痛作用以复方846为好,其次为静松灵/氯胺酮、氯丙嗪/静松灵、氯丙嗪/氯胺酮、氯丙嗪/乙醚;麻醉维持时间复方846最长(133.70±9.66),其次为静松灵/氯胺酮(89±9.9);从手术安静顺利情况看,复方846、静松灵/氯胺酮优于其它组;从伤口愈合情况看,静松灵/氯胺酮优于其它组。综合比较:复方846、静松灵/氯胺酮用于大的临床麻醉,效果确实。     

What to do with “I Don't Know:” Elicitation in Ethnographic & Survey Interviews

When a researcher enters an interview, she has already construed it as being a standard type of communicative event. This article considers how a researcher's construal of a communicative event as either an ethnographic or survey interview shapes the production of information. Interview standards entail epistemological assumptions that directly inform the type of information sought and produced. I consider this process through a comparison of the elicitation techniques I employed in survey and ethnographic interviews conducted during research in Mexico. I draw on theory in linguistic anthropology on the nature of meaning in language, examining how dialogicality and interaction are essential to understanding the construal of communicative events.     

交际策略的教学与运用

汉语学现代转型的前提批判

在漫长的历史发展过程中,西方语言文字(印欧语)是沿着音声中心/文字弱化的路径演变的,音义二极性是西方语言学的大前提。而汉语言文字自秦汉以来发生的形态类型简化和汉字形声化的整体演变趋势,则是音声弱化/文字中心的演变路径,形音义三极性是汉语学的大前提。由于中西语言文字类型的体制性差异,汉语学理应把现代转型理解成一个包含三重辩证对立同一关系的概念体系:对立于传统,即现代与前现代应在本体论上实现辩证同一;对立于自身,即元语言与对象语言、主观语法与客观语法应在认识论上实现辩证同一;对立于西方,即个性与共性、民族性与现代性应在方法论上实现辩证同一。     

论发展观的历史研究

发展和发展观是发展观历史研究的前提,发展观历史研究是发展观理论研究的基础,发展观历史研究要把民族、国家作为基本单元,把发展阶段作为主要背景,把发展问题作为重点内容。     

词汇研究新趋势与英汉词汇对比研究的方法和内容

经过100多年的演变和发展,现代语言学研究取得了丰硕的成果,对词汇研究产生了巨大的影响。为适应词汇研究的新趋势,现代英汉词汇对比研究应突破传统的窠臼,找准确有可比性的研究对象,在理论和方法上显示现代哲学、现代语言学、现代语义学和数理语言学的特色。     

习近平治国理政的哲学方法论探略

党的十八大以来,以习近平同志为核心的党中央立足当代中国、把握世界大势,提出了一系列治国理政的新理念新思想新战略,有力推动中国特色社会主义进入新时代,形成了习近平新时代中国特色社会主义思想。习近平总书记高度重视学习和掌握辩证唯物主义和历史唯物主义,将其视为中国共产党人的“看家本领”。马克思主义哲学为习近平治国理政提供了总的方法论遵循。辩证唯物主义特别是其中的实事求是的实践观、事物联系发展的观点、具体问题具体分析的矛盾观提供了思维方法的总依据;历史唯物主义关于人民主体地位的思想和群众路线群众观点则贯穿于其治国理政全过程,彰显着中国共产党的价值自觉、理论自觉与实践自觉,奠定了习近平治国理政新理念新思想新战略的整个基石。     

An access network design problem with end-to-end QoS constraints

In this paper, we present an access network design problem with end-to-end quality of service (QoS) requirement. The problem can be conceptualized as a two-level hierarchical location-allocation problem on the tree topology with nonlinear side constraints. The objective function of the nonlinear mixed integer programming model minimizes the total cost of switch and fiber cable, while satisfying demand within the prescribed level of QoS. By exploiting the inherent structure of the nonlinear QoS constraints, we develop linearization techniques for finding an optimal solution. Also, we devise an effective exact optimal algorithm within the context of disjunctive constraint generation. We present promising computational results that demonstrate the effectiveness of the proposed solution procedure.
