用复杂性思维看教学

复杂性是二十一世纪的科学,它是“偶然性和无序性的不可消除”、“多样性的统一”、“非线性和非平衡”、“来自无序的有序”。复杂性研究改变了人们的思维方式,为教育教学研究的发展提供了新思路、新方法——教学目标的多元思维,教师备课的非线性思维,师生关系的悖论思维,教学活动过程的动态生成性和教育结果的不确定性。     

和谐社会与法律监督研究综述

第三届国家高级检察官论坛马上就要落下帷幕了,回顾两天的研讨,我感受颇深.这次论坛的特点可以概括为:"四多"、"四高"."四多"就是论文的数量多、与会的专家多、参会的代表多、浦东的投入多."四高"就是论文的质量高、专家的水平高、代表的规格高、浦东的热情高.     

草豆蔻有效部位对奶牛乳腺炎病原菌的抗菌活性研究

采用琼脂平板2倍稀释法测定了草豆蔻水提物、醇提物、醇-水提取物、挥发油4个活性部位对15个不同种属120株奶牛乳腺炎病原菌的最低抑菌浓度,用SPSS17.0软件中单因素方差分析法比较分析了4个活性部位分别对金黄色葡萄球菌、鲁氏不动杆菌和芽孢杆菌等11种菌株的抑菌活性的强弱;采用小鼠全身感染模型分析了草豆蔻油对金黄色葡萄球菌和大肠杆菌的体内抗菌活性。结果显示,草豆蔻4个活性部位对受试菌有不同程度的体外抗菌活性,且对革兰氏阳性菌的抗菌活性较对革兰氏阴性菌的活性强;在4个活性部位中,以挥发油的体外抗菌活性最强,除对4株单胞菌和7株大肠杆菌无抑菌活性外,对其余109株受试菌均有较强的活性,对革兰氏阳性菌的MIC50和MIC90分别为0.94～1.87mg/mL和0.47～1.87mg/mL,对革兰氏阴性菌的MIC50和MIC90均为0.47～29.92mg/mL。草豆蔻油在体内对金黄色葡萄球菌感染模型小鼠和大肠杆菌感染模型小鼠有强的保护作用。高、中、低3个剂量对金黄色葡萄球菌感染模型小鼠的保护率分别为100%、90%、80%,对大肠杆菌感染模型小鼠的保护率分别为100%、90%、40%,呈明显量效关系。结果表明,草豆蔻挥发油是中药草豆蔻对奶牛乳腺炎病原菌的抗菌活性物质,可用于奶牛乳腺炎等感染性疾病的防治和食品防腐剂的开发。     

三江并流地区经济活动对生态环境的影响及天然林的保护对策

三江并流地区属金沙江、澜沧江、怒江的上游地带,是属于全国仅存的几处天然林资源地区之一.近20年来,当地的天然林资源遭到极大的破坏.根据云南大学唤青社2000年7～8月对该地区的徒步考察,针对这一地区存在的薪柴消耗、畜牧业发展、矿产开发、旅游开发、森工企业对天然林及生态环境的影响形式,提出了调整产业结构、加强教育投资、实行矿产开发中的生态保护、谁受益谁补偿、提高群众环保意识等天然林保护对策,以促进西部环境保护和西部大开发的可持续发展.     

Comparison of 12-Year-Old Children with Prenatal Exposure to Cocaine and Non-Exposed Controls on Caregiver Ratings of Executive Function

Differences in caregiver reported executive function in 12-year-old children who were prenatally exposed to cocaine (PCE) compared to children who were not prenatally exposed to cocaine (NCE) were assessed. One hundred and sixty-nine PCE and 169 NCE, primarily African-American, low socioeconomic status children participated in a prospective longitudinal study. The Behavior Rating Inventory of Executive Function (BRIEF) Parent Form was administered. Two broadband BRIEF scores (Behavioral Regulation Index (BRI) and Metacognition Index (MI)) and a summary Global Executive Composite (GEC) were computed. Multiple and logistic regression analyses were used to assess the effects of amount of PCE on executive function, controlling for covariates including caregiver (rater) psychological distress, child’s gender and other prenatal drug exposure variables. After adjustment for covariates, amount of PCE was associated with the GEC and two MI subscales, Plan/Organize and Monitor, with heavier exposure associated with more problems of executive function. An amount of PCE by gender interaction revealed amount of PCE effects in other remaining subscales of the MI (Initiate, Working Memory, and Organization of Materials) only among girls. Head circumference did not mediate the effects of cocaine on outcomes. Higher current caregiver psychological distress levels were independently associated with poorer ratings on the executive function scales. Assessment and targeted interventions to improve metacognitive processes are recommended for girls who were prenatally exposed to cocaine.     

畋论刑事诉讼基本原理（上）

本文探讨了有关刑事诉讼基本原理的若干问题。所谓“刑事诉讼基本原理”,就是对刑事诉讼产生决定性影响的一些带有规律性的东西,或者说是具有指导意义的一些理念。本文概述了九项基本原理,它并非是与司法实践毫无关系的纯学术研究,而是对诉讼立法与司法实践都有重要的指导意义。

重视对思想政治教育接受问题的研究

思想政治教育接受问题是思想政治教育研究的新领域。重视这一问题的研究 ,不仅在理论上扩展了思想政治教育研究的广度和深度 ,而且在实践上有利于增强思想政治教育的针对性和有效性。     

Transnational Human Rights Networks

'Transnational human rights networks' has become a hot research topic for international human rights studies in recent years. It mainly documents and theorizes the transnationalization or internationalization of human rights norms and practices during the last several decades. It began as a distinctive field of research scholarship and has grown to challenge the traditional approaches to international studies. This review introduces the major tenets of this field and, without downplaying their contribution to international studies, it also tries to point out several problems in the conceptualization, theorization and methodology of the current studies on human rights networks. This critical analysis is followed by some suggestions for future studies.     

论刑事立案监督权能的强化
