Towards Universal Text Retrieval: Tipster Text Retrieval Research at New Mexico State University     

Mark W. Davis  William C. Ogden 《Information Retrieval》2000,3(4):339-356

New Mexico State University's Computing Research Lab has participated in research in all three phases of the US Government's Tipster program. Our work on information retrieval has focused on research and development of multilingual and cross-language approaches to automatic retrieval. The work on automatic systems has been supplemented by additional research into the role of the IR system user in interactive retrieval scenarios: monolingual, multilingual and cross-language. The combined efforts suggest that universal text retrieval, in which a user can find, access and use documents in the face of language differences and information overload, may be possible.  相似文献

External stimulus control of target-directed attack and biting elicited by tailshock     

Stephen F. Davis  James W. Voorhees  Mary Nell Travis-Neideffer 《Learning & behavior》1979,7(1):95-98

Two experiments evaluating the effects of external stimuli on attack and biting in rats elicited by electric tailshock are reported. In the first experiment, stimuli presented to four groups of test subjects consisted of a stimulus animal, a stimulus animal plus taped vocalizations of a rat experiencing shock, an inanimate object, and an inanimate object plus taped vocalizations. Subjects in a fifth (control) group were tested in the absence of these stimuli. The presence of another animal in the test situation significantly increased the amount of target-directed responding. A decrease in responding, rather than increase, was shown by the subjects tested under the stimulus-object plus taped-vocalization conditions. Experiment 2 investigated the salient features of the stimulus animal and found a combination of both olfactory and visual cues to be most effective in eliciting target-directed responding. These studies indicate that the amount of target-directed attack and biting shown in this situation may be related causally to the type of sensory input received by the test animal.  相似文献

The role of feedback from phonology to orthography in orthographic learning: an extension of item‐based accounts     

Meredith McKague  Chris Davis  Chris Pratt  Michael B. Johnston 《Journal of Research in Reading》2008,31(1):55-76

Skilled readers were trained to recognise either the oral (n=44) or visual form (n=40) of a set of 32 novel words (oral and visual instantiation, respectively). Training involved learning the ‘meanings’ for the instantiated words and was followed by a visual lexical decision task in which the instantiated words were mixed with real English words and untrained pseudowords, and the instantiated words were to be considered as words. The phonology‐to‐orthography consistency (feedback consistency) of the instantiated words was manipulated to investigate the role of feedback from phonology in orthographic learning. Masked consonant and vowel‐preserving form primes were used in the lexical decision task as probes of orthographic learning. Feedback‐consistent instantiated words were recognised significantly faster in lexical decision than feedback‐inconsistent instantiated words, and facilitation was significantly greater from consonant‐preserving than vowel‐preserving primes for orally but not visually instantiated words. The results support the hypothesis that orthographic representations based on a consonant frame can be generated from the speech signal before encountering the printed forms, and that feedback from phonology is involved in the early stages of orthographic learning.  相似文献   

Educational administration and history Part 1: debating the agenda     

Helen M. Gunter  Tanya Fitzgerald 《Journal of educational administration and history》2008,40(1):5-21

In this first editorial paper we scope the terrain on which the JEAH is located and consider the knowledge production process that will shape the journal and, in turn, enable the journal to shape what is known and what is worth knowing. We begin by making a case for productive pluralism where we assert that the JEAH is not directly connected to a particular society or epistemic group, and so the opportunity exists for a range of work that focuses on historical understandings of educational administration to be published. We make the argument that educational administration is a field of study and practice, and that it can draw on historical perspectives and research designs to enable new insights and theoretical explanations to be developed.  相似文献   

Intersecting communities of practice in distance education: the program team and the online course community     

Ana‐Paula Correia  Niki Davis 《Distance Education》2008,29(3):289-306

This article is a case study that aimed at understanding the dynamics of two complementary communities involved in a distance education graduate program: one community of practice formed by the instructors and instructional developers, who designed and developed the program, and another created by the students and instructor in one of the online courses. The relationship between both communities and the evolution that occurred within the online course are analyzed. Emergent themes are discussed and recommendations are made for similar contexts and communities.  相似文献   

Education for citizenship: The role of progressive education and interdisciplinary studies     

Newell  William H.  Davis  Allen J. 《Innovative Higher Education》1988,13(1):27-37

Critiques of education from both the left and right conclude that educational institutions hold the key for involving more citizens in the political process. While neither progressive nor interdisciplinary education is sufficient by itself to prepare students for what we identify as the chief requirements for citizenship in the 21st century-civic literacy, critical thinking, social conscience, tolerance and respect for diversity, global citizenship, and political action-a combination of the two can meet all six requirements. We propose an action agenda for high education that includes promoting student involvement in off-campus political projects and on-campus governance, modifying mission statements and promotion/tenure criteria, and offering interdisciplinary general education courses at the beginning and end of college that are progressively taught, and registering students to vote.Newell was the founding president of the Association for Integrative Studies, author ofInterdisciplinary Undergraduate Programs and several articles on interdisciplinary higher education, and a veteran of 19 years of interdisciplinary teaching.Dr. Davis has administered progressively taught institutions for college students, high school students, and the elderly. He is currently Executive Director of the United Way of Franklin County, Massachusetts, applying the same principles to community service agencies.  相似文献   

Giving the “Viewser” a Voice? Situating the Individual in Relation to Personalization,Narrowcasting, and Public Service Broadcasting     

Tanya Kant 《广播与电子媒介杂志》2014,58(3):381-399

This article undertakes a critical comparison of contemporary personalization practices on Web platforms such as YouTube and Facebook with long-established practices of narrowcasting. Though such platforms appear to adhere to goals of universality similarly adhered to by public service broadcasting (PSB), the implementation of personalization on these platforms proves problematic to their discursive positioning as free “public” services. Furthermore, though public service broadcasters have embraced personalization in the name of pluralism, critics suggest that the narrowcasting inherent in personalization exists in tension to PSB's enduring commitments. Finally, the article argues that system-initiated personalization negates the “consumer sovereignty” that narrowcasting has traditionally mobilized.  相似文献   

From a System of Journals to a Web of Objects     

Herbert Van de Sompel  Susan Davis 《期刊图书馆员》2015,68(1-4):51-63

Herbert Van de Sompel, Prototyping Team Leader, Research Library of the Los Alamos National Laboratory, took the audience on a journey from a paper-based scholarly communication system to a web of objects. Increasingly, the research process, not just its output, is web-based. Objects created and used as part of that process do not have the same sense of fixity that traditional publications had. Van de Sompel explored the problems inherent in the transition and the consequences of failing to proactively archive the full context of the scholarly record on the web.  相似文献
