成长、转徙、回望——论徐则臣文学的发轫

徐则臣作为"70后"的代表作家,在当今文坛可谓炙手可热。目前,研究界大多将关注点放在他的"花街"系列及之后的作品,而对他的成长经历以及他步入文坛的过程鲜有论述。徐则臣将淮安视为文学故乡,在花街上建构自己的文学世界,而将现实故乡东海作为写作的素材库,两地分属一表一里,在徐则臣的小说中相互融合。本文在叙述徐则臣转徙经历的同时,兼谈他的转徙经历对其小说创作的影响。     

The design and development of a dyscalculia checklist based on a focus group interview

This article aims to explore the symptoms and characteristics of dyscalculia. This is a qualitative study. Five experts in the field of special education took part in a focus group interview. Each expert had more than ten years of experience in their area of expertise. To determine the content validity of the protocol, three experts in special education, language and qualitative research evaluated each of the eight items. Cohen's kappa analysis was used to assess inter-rater reliability. The findings of this study indicate that 59 items have been developed, based on six constructs in the dyscalculia checklist. The six constructs were subitising, estimating, Arabic numerals, verbal numbers, arithmetic facts and calculating processes. Following the focus group interview, a new construct emerged: math anxiety. The study implies that teachers might utilise this checklist to carry out early detection of students with dyscalculia in primary schools. This will enable appropriate intervention, resulting in significant benefits for the Ministry of Education, for educators and teachers, and for the students themselves. Although this study was based in Malaysia, the results have wider implications because dyscalculia is present everywhere.

A self-contained polymeric cartridge for automated biological sample preparation

Sample preparation is one of the most crucial processes for nucleic acids based disease diagnosis. Several steps are required for nucleic acids extraction, impurity washes, and DNA/RNA elution. Careful sample preparation is vital to the obtaining of reliable diagnosis, especially with low copies of pathogens and cells. This paper describes a low-cost, disposable lab cartridge for automatic sample preparation, which is capable of handling flexible sample volumes of 10 μl to 1 ml. This plastic cartridge contains all the necessary reagents for pathogen and cell lysis, DNA/RNA extraction, impurity washes, DNA/RNA elution and waste processing in a completely sealed cartridge. The entire sample preparation processes are automatically conducted within the cartridge on a desktop unit using a pneumatic fluid manipulation approach. Reagents transportation is achieved with a combination of push and pull forces (with compressed air and vacuum, respectively), which are connected to the pneumatic inlets at the bottom of the cartridge. These pneumatic forces are regulated by pinch valve manifold and two pneumatic syringe pumps within the desktop unit. The performance of this pneumatic reagent delivery method was examined. We have demonstrated the capability of the on-cartridge RNA extraction and cancer-specific gene amplification from 10 copies of MCF-7 breast cancer cells. The on-cartridge DNA recovery efficiency was 54-63%, which was comparable to or better than the conventional manual approach using silica spin column. The lab cartridge would be suitable for integration with lab-chip real-time polymerase chain reaction devices in providing a portable system for decentralized disease diagnosis.     

处女峰攀登路线的设计与实践研究——以若尼Ⅱ峰为例

设计攀登路线是成功攀登处女峰的关键,因为一条确定的攀登路线将为后续攀登者提供安全保障,也为后来者开辟新的攀登路线提供参考,所以每一次处女峰攀登的准备都是冒着生命危险勘测、设计攀登路线的过程.登山运动中,路线设计、选择的正确与否直接关系登山队员的生命安全和攀登的成败.以若尼Ⅱ峰为例,探索研究处女峰攀爬路线的设计和选择方法...

试论竞技体育教练员的理性思维

竞技体育教练员所从事的工作是属于创造性的工作，创造性的工作离不开创造性的思维，而创造性的思维又是以科学而严密的理性思维作为基础的。作为训练和比赛的直接控制者和指挥者，要使自己的工作建立在一种科学、严密的层次上，并且能使自己的训练具有超前性、先进性和创造性，科学抽象的思维方法、科学联想的思维方法、科学组合的思维方法、历史和逻辑的统一思维、分析和综合思维及创造性思维应是教练员必须具备的能力。
