This study examined the occurrence of color in dissertations and theses produced at the Pennsylvania State University over a nine year period. Since the most common preservation method for dissertations and theses is monochromatic microfilming, traditional treatment may result in a loss of information encoded in color in these resources. Results indicate a significant increase in the use of color over the time period studied. Variations in the amount of color use by discipline were also observed. Implications related to monochromatic microfilming and recommendations for long term preservation are discussed.  相似文献

There is a widespread view held by health clinicians that their work effectiveness is impaired by 'information overload.' Building upon a previous work by Wilson, a review of the literature was undertaken to look for the evidence of this. It was found that the literature, particularly in the context of the clinical environment, was limited. This review explores the diverse overarching theories of information overload, effects of the phenomenon that are perceived to occur and proposed solutions to this problem. Many of the papers noted an information explosion but only three authors explicitly attempted to measure both the quantity and the complexity of this information. It was also found that the typology of the information studied was severely limited with most studies exploring information such as guidelines, access to journals, research findings and other knowledge intensive areas. Solutions proposed seem to concentrate on technological means rather than exploring the use of humans either in management of information or as a step in the filtering process.  相似文献

Chat reference refers to the use of instant messaging and call center software to support interactive text or voice communication with library patrons. Instant messaging has been integrated into many e-commerce environments, and into the social lives of many teenagers and young adults, affording a level of immediacy and intimacy not possible with e-mail applications. The convergence and interoperability of new and emerging technologies can be used to develop new communities of users that view libraries as being essential to their education, patient care, and research activities.  相似文献

In response to curricular changes, many academic health sciences librarians have participated in curriculum planning and/or developed informatics course requirements for students enrolled at health sciences universities. This article describes the use of clinical vignette assignments, student journal club activities, and vignette-type multiple choice questions to teach and assess skills related to managing biomedical information, communicating effectively, basic computing, and life-long learning.  相似文献

The development of English language learners (ELLs) was explored from kindergarten through eighth grade within a nationally representative sample of first-time kindergartners (N = 19,890). Growth curve analyses indicated that, compared to native English speakers, ELLs were rated by teachers more favorably on approaches to learning, self control, and externalizing behaviors in kindergarten and generally continued to grow in a positive direction on these social/behavioral outcomes at a steeper rate compared to their native English-speaking peers, holding other factors constant. Differences in reading and math achievement between ELLs and native English speakers varied based on the grade at which English proficiency is attained. Specifically, ELLs who were proficient in English by kindergarten entry kept pace with native English speakers in both reading and math initially and over time; ELLs who were proficient by first grade had modest gaps in reading and math achievement compared to native English speakers that closed narrowly or persisted over time; and ELLs who were not proficient by first grade had the largest initial gaps in reading and math achievement compared to native speakers but the gap narrowed over time in reading and grew over time in math. Among those whose home language is not English, acquiring English proficiency by kindergarten entry was associated with better cognitive and behavioral outcomes through eighth grade compared to taking longer to achieve proficiency. Multinomial regression analyses indicated that child, family, and school characteristics predict achieving English proficiency by kindergarten entry compared to achieving proficiency later. Results are discussed in terms of policies and practices that can support ELL children's growth and development.  相似文献

The referential, sequential, and inferential dimensions of discourse are explicated and discussed in order to obtain a vantage point from which to view the contributions of speech‐act theory to our understanding of human communication processes. A preview is then provided of four papers, each of which explores the intersection of two or more of these dimensions in order to enrich our understanding of speech‐act theory.  相似文献
