Beyond traditional collaborative search: Understanding the effect of awareness on multi-level collaborative information retrieval     

Nyi Nyi Htun  Martin Halvey  Lynne Baillie 《Information processing & management》2018,54(1):60-87

Although there has been a great deal of research into Collaborative Information Retrieval (CIR) and Collaborative Information Seeking (CIS), the majority has assumed that team members have the same level of unrestricted access to underlying information. However, observations from different domains (e.g. healthcare, business, etc.) have suggested that collaboration sometimes involves people with differing levels of access to underlying information. This type of scenario has been referred to as Multi-Level Collaborative Information Retrieval (MLCIR). To the best of our knowledge, no studies have been conducted to investigate the effect of awareness, an existing CIR/CIS concept, on MLCIR. To address this gap in current knowledge, we conducted two separate user studies using a total of 5 different collaborative search interfaces and 3 information access scenarios. A number of Information Retrieval (IR), CIS and CIR evaluation metrics, as well as questionnaires were used to compare the interfaces. Design interviews were also conducted after evaluations to obtain qualitative feedback from participants. Results suggested that query properties such as time spent on query, query popularity and query effectiveness could allow users to obtain information about team's search performance and implicitly suggest better queries without disclosing sensitive data. Besides, having access to a history of intersecting viewed, relevant and bookmarked documents could provide similar positive effect as query properties. Also, it was found that being able to easily identify different team members and their actions is important for users in MLCIR. Based on our findings, we provide important design recommendations to help develop new CIR and MLCIR interfaces.  相似文献

Phonological Awareness Skills in Young Boys with Duchenne Muscular Dystrophy     

Phoebe Waring  Gail Woodyatt 《International Journal of Disability, Development & Education》2011,58(2):155-168

Substantial research has detailed the reading deficits experienced by children with Duchenne muscular dystrophy (DMD). Although phonological awareness (PA) is vital in reading development, little is known about PA in the DMD population. This pilot study describes the PA abilities of a group of five young children with DMD, comparing the results with those of a group of children with spinal muscular atrophy and with those of a group of typically developing children. The Preschool and Primary Inventory of Phonological Awareness was used to assess the PA skills of the participants. Results indicated that the children with DMD performed significantly poorer than the typically developing group on tests of Syllable Segmentation, Rhyme Awareness, Alliteration Awareness and Phoneme Isolation and significantly poorer than the spinal muscular atrophy group on Rhyme Awareness. The findings of this pilot study indicate that children with DMD may have an increased risk of having PA difficulties, thus requiring early PA training.  相似文献   

人·情·文——魏晋玄学与文学漫议     

郭常亮 《赣南师范学院学报》2004,25(4):76-77

魏晋南北朝是一个"人的觉醒"的时代,这集中体现为魏晋玄学中关于人的问题的哲学思考。"人的觉醒"带来了"文的自觉"。魏晋玄学中对人的情感的大胆肯定,直接影响到当时的文学创作和文学观念的变革与更新。"情感"在文学艺术中的重要性得到认同,文学艺术由重叙事到重抒情的转变,在一定程度上反映了这种影响。  相似文献

协奏曲的钢琴改编谱演奏初探     

岳磊  姜筑 《贵州教育学院学报》2011,(7):45-47

在演奏管弦乐队协奏曲总谱改编的钢琴谱时,应当具备对文本（乐谱）的分析能力。而当以钢琴替代乐队时,钢琴协奏者实际上就承担着双重的责任：演奏者、指挥者。对此,钢琴协奏者必须有明确的认识,建立起积极而非被动的协作意识。具备理性的分析和认识是第一步,但毕竟协奏曲钢琴部分的演奏与钢琴独奏有相当明显的区别,因此,在演奏理念和演奏技巧上也要作相应的调节。  相似文献
