城市化:中国少数民族语言使用功能的变化

城市化带来少数民族语言使用功能的变化.少数民族都广泛兼用国家交际共同语,在语言的选择和使用上表现出对共同语的广泛认同;少数民族自我母语出现代际差异;城市少数民族母语使用能力弱化.引起的主要原因在于杂居的分布局面及少数民族语言使用者自身观念的改变等.

Diversity change of microbial communities responding to zinc and arsenic pollution in a river of northeastern China

Pollution discharge disturbs the natural functions of water systems. The environmental microbial community composition and diversity are sensitive key indicators to the impact of water pollutant on the microbial ecology system over time. It is meaningful to develop a way to identify the microbial diversity related to heavy metal effects in evaluating river pollution. Water and sediment samples were collected from eight sections along the Tiaozi River where wastewater and sewage were discharged from Siping City in northeastern China. The main pollutants contents and microbial communities were analyzed. As the primary metal pollutants, zinc (Zn) and arsenic (As) were recorded at the maximum concentrations of 420 and 5.72 μg/L in the water, and 1704 and 1.92 mg/kg in the sediment, respectively. These pollutants posed a threat to the microbial community diversity as only a few species of bacteria and eukaryotes with strong resistance were detected through denaturing gradient gel electrophoresis (DGGE). Acinetobacter johnsonii, Clostridium cellulovorans, and Trichococcus pasteurii were the dominant bacteria in the severely polluted areas. The massive reproduction of Limnodrilus hoffmeisteri almost depleted the dissolved oxygen (DO) and resulted in the decline of the aerobic bacteria. It was noted that the pollution reduced the microbial diversity but the L. hoffmeisteri mass increased as the dominant community, which led to the overconsuming of DO and anaerobic stinking water bodies. Water quality, concentrations of heavy metals, and the spatial distribution of microbial populations have obvious consistencies, which mean that the heavy metals in the river pose a serious stress on the microorganisms.     

论玛丽·沃斯通克拉夫特的女性主义思想

作为西方女权主义历史上的奠基人物,玛丽·沃斯通克拉夫特以法国大革命天赋人权思想与自由主义哲学为理论依据探讨两性差异,分析女性从属地位的根源,提出通过教育培育女性的理性,主张社会政治制度的改革,呼吁给予女性与男性平等的社会权利,挑战男权主义传统。本文以文本资讯为依据,对沃斯通克拉夫特针对两性差异的哲学思考、性格培育理论、理性教育主张以及女性政治权利的诉求进行探讨分析。

Electric wheelchair control system using brain-computer interface based on alpha-wave blocking

A brain-computer interface （BCI） -based electric wheelchair control system was developed, which enables the users to move the wheelchair forward or backward, and turn left or right without any pre-learning. This control system makes use of the amplitude enhancement of alpha-wave blocking in electroencephalogram （EEG） when eyes close for more than 1 s to constitute a BCI for the switch control of wheelchair movements. The system was formed by BCI control panel, data acquisition, signal processing unit and interface control circuit. Eight volunteers participated in the wheelchair control experiments according to the preset routes. The experimental results show that the mean success control rate of all the subjects was 81.3%, with the highest reaching 93.7%. When one subject＇s triggering time was 2.8 s, i.e., the flashing time of each cycle light was 2.8 s, the average information transfer rate was 8.10 bit/min, with the highest reaching 12.54 bit/min.     

大学生网络成瘾及其影响因素的Logistic回归分析

目的：了解大理市高校在校大学生网络成瘾现状及其影响因素,为大学生网络成瘾预防、干预和治疗提供理论依据。方法：采用分层整群随机抽样方法,以网络成瘾诊断量表对大理市某高校在校的一至四年级学生进行流行病学现况调查。结果：该校大学生网络成瘾倾向发生率为16.5%,年龄、性别、上网目的、与同学的关系、初次上网年龄段和每次上网持续时间在正常组和成瘾组网络成瘾发生率之间存在统计学差异（P〈0.05）;通过Logistic多因素回归分析显示,性别、上网持续时间、初次上网年龄段和参加课外活动情况是个体网络成瘾发生的危险因素,社会人际交往能力是网络成瘾发生的保护性因素。结论：在校大学生中网络成瘾发生率较高,影响到了大学生的身心健康,应尽早采取有针对性的干预措施减少网络成瘾倾向的发生。
