A critically transformative education continues to be at the center of Tucson Unified School District's (TUSD) equity and academic excellence mission. Through the use of the Social Transformation paradigm and the lesson learned from the implementation of the Critically Compassionate Intellectualism Model, TUSD once again created a cutting edge transformative, cultural, ethnic, multicultural, equity-based curricula that seeks to stimulate the blossoming intellectual capacities of our students. It presents the opportunity to build foundations and structures of collective and individual agency. Along the lines of agency, it promotes what is called barriorganic intellectualism and the nurturing of gardens of intellectualism (jardines del intelectualismo) that provide opportunities for both the academic and personal transformation of our students.  相似文献

This paper describes the state of the art in knowledge structuring techniques. A classification of the most popular methods and tools is proposed. Stress is put on visual techniques as a powerful mind tool. Object-structured analysis, which works as a knowledge-stratification method, is discussed.  相似文献

Query suggestions have become pervasive in modern web search, as a mechanism to guide users towards a better representation of their information need. In this article, we propose a ranking approach for producing effective query suggestions. In particular, we devise a structured representation of candidate suggestions mined from a query log that leverages evidence from other queries with a common session or a common click. This enriched representation not only helps overcome data sparsity for long-tail queries, but also leads to multiple ranking criteria, which we integrate as features for learning to rank query suggestions. To validate our approach, we build upon existing efforts for web search evaluation and propose a novel framework for the quantitative assessment of query suggestion effectiveness. Thorough experiments using publicly available data from the TREC Web track show that our approach provides effective suggestions for adhoc and diversity search.  相似文献

The most granular level at which COUNTER currently requires reporting of usage is for the individual journal. A number of developments have, however, meant that it is now practical to investigate the development of a COUNTER standard for the recording, reporting, and consolidation of usage statistics at the individual article level. The aim of PIRUS2 (Publisher and Institutional Repository Usage Statistics 2) was to take forward the outcomes of the original PIRUS project and build on its recommendations, by developing a prototype service (including technical, organizational, and economic models) that will enable publishers, repositories, and other organizations to generate and share authoritative, trustworthy usage statistics for the individual articles and other items that they host. The PIRUS2 project was completed in June 2011. This article covers the aims, objectives, outputs and recommendations of the project.  相似文献

The authors observed 730 collegiate students in the library and recorded their study (or non-study) activities. Approximately 60% of behaviors were study related. The most commonly observed behavior was reading print material (18.8%). The second most common behavior was the use of social media (11.4%). These results have implications for understanding how students learn and study in the pervasive digital world.  相似文献

The growing ubiquity of mobile telephony able to send e-mail raises new questions, and renews old issues, about the effect of the medium on a message. This article reports experimental results testing effects of user- and medium-generated cues on perceptions of message senders. Grounded in warranting theory, we assess the interaction of low- and high-warrant cues on perceptions of the sender's professionalism, hypothesizing senders of grammatically accurate messages are perceived as more credible. However, we also hypothesize an interaction between grammatical accuracy and the system-generated high-warrant cues from the mobile device used to send the message. Responses from 111 students assessing the credibility of an e-mail sender indicate that, although a message's user-generated content (grammatically accurate vs. erred) influences receiver's perceptions, negative attributions are attenuated by cues reflecting the transmission medium (i.e., a message's mobile signature block). Findings offer theoretical implications for warranting theory. Additionally, results suggest practitioners need to craft a message and indicate the transmission medium strategically to mitigate any impacts on attributions of professionalism to message receivers.  相似文献

Adapted from Chang et al.'s (2006) models, this study examines factors that influence adoption and non-adoption of social network sites (SNS) in adopters (Continuers, Discontinuers) and non-adopters (Potentials, Resistors). Chi-square and t-test were used to analyze the survey data of Singapore's working adults and Internet users (N =222). The findings reveal innovation characteristics (relative advantage, compatibility, complexity) and perceived popularity differ significantly in three pairs of adopter categories. Results show Continuers and Potentials are concerned more about image than Discontinuers and Resistors, while technology cluster differs between adopter vs. non-adopter and Continuers vs. Discontinuers. Moreover, the study suggests younger people tend to adopt SNSs, females continue to use SNSs more, and potential SNS users are more innovative. Lastly, a regression model to forecast the adoption of SNSs is proposed in which age, compatibility, technology cluster, and perceived popularity are predictors.  相似文献

This study summarizes a survey conducted to discover the extent to which professional librarians in Nigerian university libraries have achieved academic/faculty status. The survey revealed that: (1) almost all professional librarians (16 or 80%) in Nigerian universities have full faculty status, coupled with mandatory research and publication for promotion, in 17 (85%) of the libraries; (2) publications in subject-fields and in library/information science carry equal ratings; and (3) academic librarians in Nigeria are entitled to the same rights, privileges and responsibilities as their teaching counterparts. This paper urges the Nigerian Library Association and the Committee of University Librarians to set standards for the attainment of faculty/academic status for professional librarians in Nigerian universities and colleges.  相似文献
