Scaling behavior of nucleotide cluster in DNA sequences

In this paper we study the scaling behavior of nucleotide cluster in 11 chromosomes of Encephalitozoon cuniculi Genome. The statistical distribution of nucleotide clusters for 11 chromosomes is characterized by the scaling behavior of P（S） ∝ e^-αs＇ where S represents nucleotide cluster size. The cluster-size distribution P（S1＋S2） with the total size of sequential C-G cluster and A-T cluster S1＋S2 were also studied. P（S1＋S2） follows exponential decay. There does not exist the case of large C-G cluster following large A-T cluster or large A-T cluster following large C-G cluster. We also discuss the relatively random walk length function L（n） and the local compositional complexity of nucleotide sequences based on a new model. These investigations may provide some insight into nucleotide cluster of DNA sequence.     

Science Teacher Efficacy and Extrinsic Factors Toward Professional Development Using Video Games in a Design-Based Research Model: The Next Generation of STEM Learning

Designed-based research principles guided the study of 51 secondary-science teachers in the second year of a 3-year professional development project. The project entailed the creation of student-centered, inquiry-based, science, video games. A professional development model appropriate for infusing innovative technologies into standards-based curricula was employed to determine how science teacher’s attitudes and efficacy where impacted while designing science-based video games. The study’s mixed-method design ascertained teacher efficacy on five factors (General computer use, Science Learning, Inquiry Teaching and Learning, Synchronous chat/text, and Playing Video Games) related to technology and gaming using a web-based survey). Qualitative data in the form of online blog posts was gathered during the project to assist in the triangulation and assessment of teacher efficacy. Data analyses consisted of an Analysis of Variance and serial coding of teacher reflective responses. Results indicated participants who used computers daily have higher efficacy while using inquiry-based teaching methods and science teaching and learning. Additional emergent findings revealed possible motivating factors for efficacy. This professional development project was focused on inquiry as a pedagogical strategy, standard-based science learning as means to develop content knowledge, and creating video games as technological knowledge. The project was consistent with the Technological Pedagogical Content Knowledge (TPCK) framework where overlapping circles of the three components indicates development of an integrated understanding of the suggested relationships. Findings provide suggestions for development of standards-based science education software, its integration into the curriculum and, strategies for implementing technology into teaching practices.     

女性群体的维权者“人主”--舅权在晋北地区的传播与发展

在晋北广大农村地区舅舅和外甥的关系是这样体现的,当进入村寨以后,经常听到人们在谈论“人主”的一些情况,尤其是在诞生礼、婚礼、丧礼等仪式当中。“人主”在严格意义上来说,是舅权的传播和发展。文章仅从人们的生活当中的仪式活动来认识“人主”这一概念,并且探讨了“人主”在当地社会生活中发挥的社会功能,以及这种功能是通过什么方式实现的。     

全日制工程硕士研究生工程实践能力调查

为有效加强全日制工程硕士研究生的工程实践能力培养,设计了以建构知识能力、表征问题能力、解决问题能力为三个一级指标的“全日制工程硕士研究生工程实践能力特征量表”,面向企业管理人员进行了调查.调查结果发现研究生工程实践能力与企业的期望之间有着明显的差距.提出高校要从更新培养方案、调整课程设置、加强案例教学、充分发挥企业导师作用等方面有的放矢地培养研究生的工程实践能力.     

论全真案例演示教学法

全真案例演示教学法是一种旨在提高学生法律实务技能的参与型案例教学方法。它包括真实的案例、学生的模拟、教师的演示和课后的总结四种主要的教学元素,与案例教学法、亚案例教学法和个案全过程教学法等均存在一定的联系和区别,具有"案例性"、"真实性"、"互动性"、"实践性"、"综合性"和"合作性"等突出特点。这一教学方法的运用具有软件和硬件两方面的要求,在操作流程上包括课前准备和课堂实施两个相对固定的阶段,能通过多种路径来提升学生的实务技能并实现多种重要的教育价值。     

从居住与交通的视角看桐城歌的民俗文化

桐城歌是安徽桐城的地方民歌,是国务院公布的首批国家级非物质文化遗产,具有鲜明的地域特色,题材广泛,内容丰富,影响广泛而深远。从当地居住与交通的视角看桐城歌的物质民俗,既展示了栩栩如生的地方风情,又彰显了魅力无穷的地方文化,为研究桐城地方民俗文化打开了又一扇窗。     

网络教学应用效果评估的定性研究

高校对于网络教学评估体系的研究刚刚起步。提出高职院校多维度评估网络教学效果的理念,明确整体性考评指标体系：不仅考评教师的教学和网络课程资源建设,更要全面考察职能部门给予的政策支持、IT部门的培训及技术服务、学生基础、系统软硬件环境等情况,并详细列出各项评估指标体系,梳理评估流程,以期提升高职院校网络教学的整体效能。     

秸秆类生物质热解的热重-红外联用分析

在氮气气氛下,利用热重-红外联用技术对来自上海市金山区的两种秸秆类生物质(水稻秸秆和芦苇秸秆)热解过程中的失重特性和气体产物释放特性进行了实时在线分析。结果表明,升温速率的增加会产生一定程度的热滞后现象,热裂解过程向高温侧移动;采用积分法对两种秸秆的热解过程进行了动力学分析,得到秸秆类生物质的热解动力学参数,水稻和芦苇秸秆的热解反应是一级反应;两种秸秆的热解产物主要为H2O、CO2、CO、CH4;水稻秸秆热解的DTG曲线及CO2的析出峰为单峰,而芦苇秸秆热解的DTG曲线及CO2的析出峰为双峰;气体析出规律的差异与秸秆中纤维素和半纤维素的比例有关。     

关于高职院校定位的思考

高职院校是职业教育与普通高等教育衔接的关键环节，它的发展使传统的职业教育在其上端重新归入国民教育体系，既完善了职业教育本身，也完善了国民教育体系。作为过渡性教育，高职院校既要有技能培养优势，又不能忽视个人的可持续发展，教育教学实施比普通高等教育更为复杂，教育教学模式创新十分迫切。
