An empirical study of query expansion and cluster-based retrieval in language modeling approach     

Seung-Hoon Na  In-Su Kang  Ji-Eun Roh  Jong-Hyeok Lee 《Information processing & management》2007

The term mismatch problem in information retrieval is a critical problem, and several techniques have been developed, such as query expansion, cluster-based retrieval and dimensionality reduction to resolve this issue. Of these techniques, this paper performs an empirical study on query expansion and cluster-based retrieval. We examine the effect of using parsimony in query expansion and the effect of clustering algorithms in cluster-based retrieval. In addition, query expansion and cluster-based retrieval are compared, and their combinations are evaluated in terms of retrieval performance by performing experimentations on seven test collections of NTCIR and TREC.  相似文献   

Religious Development in African American Adolescents: Growth Patterns That Offer Protection     

Daniel B. Lee  Enrique W. Neblett 《Child development》2019,90(1):245-259

Although religiosity promotes resilient outcomes in African American (AA) adolescents, there is a lack of research that examines the protective role of religious development in the context of stressful life events (SLEs). In 1,595 AA adolescents, a cohort-sequential design was used from ages 12 to 18 to examine subtypes of religiosity, as well as distinct developmental patterns within subtypes. The protective role of religious development was also examined in the context of SLEs. The study findings indicated two subtypes of religiosity—extrinsic and intrinsic religiosity—as well as low and high developmental patterns in the identified subtypes. Furthermore, the protective influence of extrinsic and intrinsic religiosity gradually diminished from age 12 to 18 in the context of SLEs.  相似文献   

An Entity Theory of Intelligence Predicts Higher Cortisol Levels When High School Grades Are Declining

Grades often decline during the high school transition, creating stress. The present research integrates the biopsychosocial model of challenge and threat with the implicit theories model to understand who shows maladaptive stress responses. A diary study measured declines in grades in the first few months of high school: salivary cortisol (N = 360 students, N = 3,045 observations) and daily stress appraisals (N = 499 students, N = 3,854 observations). Students who reported an entity theory of intelligence (i.e., the belief that intelligence is fixed) showed higher cortisol when grades were declining. Moreover, daily academic stressors showed a different lingering effect on the next day's cortisol for those with different implicit theories. Findings support a process model through which beliefs affect biological stress responses during difficult adolescent transitions.  相似文献

Proposing an Effective Action Learning Process Model: Introducing the PAIR Model     

Yeol Huh  Dabae Lee 《Performance Improvement》2015,54(10):22-29

Action learning differentiates itself from other inquiry‐based learning approaches in that it requires learners to take actions based on project outcomes. While implementing their plans and reflecting on consequences of their actions, learners are given more and varied learning opportunities. Despite the apparent benefits of action learning, it entails a more complex process and a higher level of involvement from top management than do ordinary training programs. This article seeks to identify benefits and limitations of action learning and proposes a process model that enhances its benefits and helps to overcome its limitations. Thirty‐one research studies from academic journals were reviewed to identify espoused benefits and limitations of action learning. Those findings were used as the foundation for development of the PAIR model.  相似文献   

Beyond the Blockbuster: Good Exhibitions in Small Packages     

Ellen W. Lee 《Curator: The Museum Journal》1994,37(3):172-184

Many American and European art museums are now featuring small, highly-focused shows in their exhibition programs. In 1990, the Indianapolis Museum of Art organized an exhibition that reunited, for the first time in a century, the four landscape paintings created by neo-impressionist Georges Seurat during the last summer of his life. Using Seurat at Gravelines: The Last Landscapes as an example, this article addresses the advantages — for museums and their visitors — of the small temporary exhibition.  相似文献

Creating information resources and trainings for farmworker-serving community health workers     

Jamie E. Bloss  Catherine E. LePrevost  Leslie E. Cofie  Joseph G. L. Lee 《Journal of the Medical Library Association》2022,110(1):113

Background:Farmworker-serving community health workers have limited access to farmworker health research findings, training, and education resources. With funding from the National Library of Medicine, we are working to improve the health information literacy of both community health workers and farmworkers. We conducted focus group discussions with community health workers to explore their experiences providing health education and information to farmworkers, their information-seeking behaviors, and their technology and information needs. Data from the focus groups provided insights into the main areas in which community health workers would like to receive professional development.Case Presentation:Our team, which includes health sciences librarians, developed a resource list of educational materials for farmworker health, videos to increase community health workers'' skills finding health information online, and webinars to introduce these resources to community health workers. Videos, available in Spanish and English, included instruction on finding and evaluating online health information, accessing reputable online consumer health information sources, and advanced searching tips for Google and PubMed. Through three webinars, we introduced the resource list, videos, and design software for creating handouts and infographics to community health workers.Conclusions:Community health workers have a critical role in providing health education and information to farmworkers, and our efforts represent a first step in addressing community health workers'' limited access to professional development. Health sciences librarians are well positioned to partner with interdisciplinary teams working to reduce health disparities and provide resources and training to community health workers, farmworkers, and other underserved communities.  相似文献   

Curriculum-based measures of written expression for learning-disabled and nondisabled students     

Jodi T. Watkinson  Steven W. Lee 《Psychology in the schools》1992,29(2):184-191

This study examined differences in written expression between a sample of learning-disabled and nondisabled middle school students, matched by grade and sex, using eight curriculum-based measures. All of the learning-disabled students had been identified as having written language deficits as part of their handicapping conditions. The nondisabled students showed superior written expression skills, especially on the production-independent measures. Implications of these results are discussed in relation to psycho educational assessment, the use of CBM for ongoing assessment of written expression, and future studies.  相似文献   

Age,aging and mega-serials in Tamil Nadu     

C. Lee Harrington 《Popular Communication》2019,17(1):35-49

This qualitative, exploratory study examines issues of age and aging surrounding mega-serial (daily soap opera) production in Tamil Nadu, India. This study is timely for demographic reasons (a rapidly aging Indian population) and for the centrality of mega-serials to India’s entertainment landscape, coupled with the genre’s long history of engaging global audiences with real-world social issues. Two data sources are utilized: focus groups with 16 mega-serial viewers and interviews with 25 members of the Tamil mega-serial industry. Situated in scholarship on gerontology/age studies and media/culture industry studies, analysis yields two broad themes related to (a) representations of age/aging and elder-oriented storylines in contemporary Tamil mega-serials and (b) recent industry changes that may forestall mega-serials’ potential to center age and aging as core narrative elements. Overall, evidence points to an industry and audience(s) in considerable transition.  相似文献
