This study aims at both investigating bullying episodes occurring at school across different grades (from 6 to 8) and evaluating whether educational achievement in math can be predicted on the ground of students' perception of school violence. The sample was composed of 11,064 students coming from middle schools of Southern Italy. Standardized tests were submitted to measure students' performance in mathematics. Background questionnaires were used to assess students' perception of school violence in relation to some bullying episodes occurring in the last month. Students' perception of school violence, which tends to decrease from Grade 6 to 8, can be considered a valid predictor of their math performance, also controlling for both individual and family background, school context, and geographical characteristics.  相似文献

This study evaluates whether or not community college libraries have in place the characteristics necessary to develop digital branch libraries to meet the expanding and changing needs of their publics. Using Hon and Grunig’s (1999) relationship building criteria as a framework, 98 community college library websites were analyzed to determine if they can be considered digital branch libraries (King, 2009). Digital branches go beyond offering mere functionality to embody relational aspects that are critical to the success of service-based organizations. That is, they provide at least the same level of services as their brick and mortar counterparts through real staff, real collection, real building, and real community. Findings indicate that while aspects of all of King’s criteria were present, representation was inconsistent and often weak; further, the emphasis was on functional features, suggesting a need for greater relationship building practices in order to engage with their publics. Collective results are discussed, and recommendations for improvement and areas of future research are offered.  相似文献

To date the development of technical systems to support learning either in schools and universities (CSCL-systems), or in companies (knowledge-management systems) have largely developed separately concurrent, with no or little mutual exchange of experience. The approach presented here seeks to combine the strengths of both lines of development in order that both benefits from each others advantages achieve advantages for each development. Detailed requirements engineering is presented regarding, three research fields: communication theory; learning processes; and a study in companies. The requirements collected led to a sophisticated concept of annotations where annotations serve as communicative contributions, and (segmented) material is used as context. The combination and distinction between communicative contributions, and the material itself is a suitable approach for integrating the advantages of CSCL-systems (communication support) and knowledge management systems (support of content storage). These requirements are combined in a software system, KOLUMBUS, presented with its key features. To gather experience with KOLUMBUS and to convey potential for further improvement, two case studies were conducted. The main results, advantages and further potentials derived from these two case studies are described in this paper. The paper concludes with design recommendations for similar technical systems, as well as organizational hints for CSCL-groups (in schools or universities as well as in companies).  相似文献

This article aims to explore the ways in which the transformations that Rio de Janeiro experienced prior to hosting the Olympics echo in the soundscapes of Favela da Maré. Here, we draw from an (auto)ethnographic approach, and combine theoretical perspectives from sound studies, auditory culture, and studies of activist media. Our research indicates that some of the authorities’ oppressive impositions on favela residents’ daily lives manifest precisely through the suppression of sounds. We would like to argue that activist media in Latin America can be better understood if situated in a complex set of daily rhythms.  相似文献

Points of contact formulate the culture of any organization and shape the perceptions of decision makers and colleagues alike. This research project investigated the interactions between Cataloging and Metadata Services staff and other library employees by analyzing interactions. This article summarizes the results of data gathered from interaction assessments and compares them with surveys about the current perceptions of the cataloging unit at the Utah State University Libraries. It discusses the ways these results have influenced existing unit workflows to enhance awareness of cataloging and metadata contributions to the library and posits possible ways to continue such initiatives moving forward.  相似文献

Outreach to research centers and institutes is often overlooked in academic libraries. This article discusses a needs assessment conducted by the Liaison Services Department at the University of Houston Libraries that reviewed library services to centers and institutes at the University of Houston's main campus. The assessment was conducted for two purposes: to build collaborations with centers and to determine how the libraries might create new services and/or market existing services to meet the centers and institutes' growing research needs.  相似文献

Key points

  • Lean methods can give rich insights: Even a few, short sessions with a handful of users can generate useful inputs for a user‐centric design process.
  • Design for beginners: An interface that supports novices will also support experts.
  • Keep it simple: Focus on functionality that supports core search and discovery tasks.
  • Popular or high‐value features should have prime position and rarely used or low‐value features should be hidden or removed.
  • Visual cues are important for usability, as is balancing the visual space.
