Performance of query processing implementations in ranking-based text retrieval systems using inverted indices

Similarity calculations and document ranking form the computationally expensive parts of query processing in ranking-based text retrieval. In this work, for these calculations, 11 alternative implementation techniques are presented under four different categories, and their asymptotic time and space complexities are investigated. To our knowledge, six of these techniques are not discussed in any other publication before. Furthermore, analytical experiments are carried out on a 30 GB document collection to evaluate the practical performance of different implementations in terms of query processing time and space consumption. Advantages and disadvantages of each technique are illustrated under different querying scenarios, and several experiments that investigate the scalability of the implementations are presented.

When a “sloppy copy” is good enough: Results of a state writing assessment

Students in grades 5 and 8 completed a state writing assessment, and their first and final drafts on the extended writing portion of the test were copied and scored using the state writing rubric. The rubric consisted of three primary traits: Content and Organization, Style and Fluency, and Language Use. Scorers were blind to the study purpose and scored either a student's first or final draft. No significant difference was found between the first and final drafts written by students in special education at both grade levels. Likewise, no significant difference was found for the writing of general education students in grade 8. A significant difference was found, however, between first and final drafts written by fifth-grade students in general education. Cross tabulations conducted at grades 5 and 8 revealed that over 50% of the first drafts received the same score or a better score than what was earned on the final draft.     

“Oh Yeah,I’m Mexican. What Type are You?” Changing the Way Preservice Teachers Interpret and Respond to the Literate Identities of Children

This writing describes a literacy project between preservice teachers enrolled in a small university in Montana and an inner city school classroom in Kansas. It shows how the preservice teachers and children negotiate meaning at the beginning of the project as well as what the preservice teachers were learning from the children and from their teacher, Scott. Twenty-three third grade children exchanged letters, cards, drawings, autobiographies, and writing about shared literature with 24 preservice teachers for 10 weeks. Scott, the third grade teacher who assisted with the project, was a former student in Rita’s university language arts classroom and was strongly committed to demonstrating to preservice teachers the rewards of teaching in an inner city classroom ... particularly those coming from communities where people of color or linguistic diversity were few. Through shared written responses and the negotiation of meaning between two age groups, this project opened pathways for greater insight into the cultures and lives of children that the university students might otherwise not have known. It also provided myriad glimpses into the lives of real children, each with his or her own interests, life experiences, and expressive modalities thus shaping the perceptions of the preservice teachers about their role as teacher in supporting and responding to the individual strengths of each child.     

竞技健美操运动员踝关节力量要求及训练方法的研究

采用文献资料、专家访谈、问卷调查、逻辑分析等研究方法,对踝关节解剖结构、竞技健美操运动员踝关节损伤现状、竞技健美操运动员踝关节力量要求及训练方法进行了调查、分析、归纳与总结。研究结果表明：人体踝关节解剖结构复杂,易出现该部位的运动损伤,竞技健美操运动项目特征对踝关节力量素质提出了较高的要求,应用赤脚加速跑、节奏性纵跳等练习提高学生的踝关节力量素质,进而达到提高竞技健美操运动员技术水平的目的。
