This study focuses on the discourse of an intercontinental on-line Master’s programme in adult learning, using English as
the lingua franca of the programme and involving four collaborating universities in Sweden, South Africa, Canada and Australia.
The programme is highly interactive, emphasising communication between students. Taking the variation in participation as
the point of departure, a discourse analysis aiming at analysing the contingencies contributing to the pattern of communication
in the programme was undertaken. Data consist of a variety of texts on-line web-documents, written notes, and narratives that
participants wrote about their lives related to participation in the programme. The use of English as the lingua franca contributed
to a mistake anxiety, which for some students was hampering their communication in the programme. Aspects of the material
world such as the vast differences in the efforts and costs for participating in the programme were also highly interrelated
to the shaping of socio-culturally situated identities among the students and thereby contributing to the variation in frequency
in participation. The results show that the official discourse of the programme as a text, with its emphasis on equity, change
and development, gets subordinated to the discourses produced and reproduced by the students in the programme as a discursive
practice and social practice. The students’ accounts reveal that there are fragments of an alternative discourse emerging,
based on mutual concern and friendship, which might suggest a potential for changing the communicative patterns in the programme. 相似文献

The present observational study of child abuse has isolated parental control strategies and child response as a promising area of investigation. The social interaction of 10 abusive and 10 matched control mothers and their preschool children was videotaped in a simulated home environment involving both structured and unstructured activities. A coding scheme was developed to record interactional behavior in each dyad. Particular emphasis was placed on the analysis of mother command/child compliance sequences. Compared to controls, abusive mothers employed more commands, and more power-assertive and less positively oriented control strategies. They were also more intrusive, more inconsistent in their use of parenting techniques, displayed more flattened affect throughout their control interactions, and were less flexible in their attempts to gain compliance from the child. In turn, children of abusive mothers demonstrated far more noncompliant behavior than their control counterparts. 相似文献

Teaching faculty in ten entry-level professional fields reported varying amounts of time devoted to teaching, research, consulting, and professional practice but did not differ in time devoted to administration. The faculty member's own role view was most closely related to time use, but for time spent in teaching and research, faculty age and institutional type (but not gender) were also significant predictors. Even after several general demographic characteristics and environmental variables that potentially differentiate professional from discipline-based faculty are taken into account, different professional fields may be characterized by group climates which influence or reinforce certain faculty roles. 相似文献

Exploiting aspectual features and connecting words for summarization-inspired temporal-relation extraction 总被引:2,自引:0,他引:2
This paper presents a model that incorporates contemporary theories of tense and aspect and develops a new framework for extracting temporal relations between two sentence-internal events, given their tense, aspect, and a temporal connecting word relating the two events. A linguistic constraint on event combination has been implemented to detect incorrect parser analyses and potentially apply syntactic reanalysis or semantic reinterpretation—in preparation for subsequent processing for multi-document summarization. An important contribution of this work is the extension of two different existing theoretical frameworks—Hornstein’s 1990 theory of tense analysis and Allen’s 1984 theory on event ordering—and the combination of both into a unified system for representing and constraining combinations of different event types (points, closed intervals, and open-ended intervals). We show that our theoretical results have been verified in a large-scale corpus analysis. The framework is designed to inform a temporally motivated sentence-ordering module in an implemented multi-document summarization system. 相似文献

Multi-candidate reduction: Sentence compression as a tool for document summarization tasks 总被引:2,自引:0,他引:2

This article examines the application of two single-document sentence compression techniques to the problem of multi-document summarization—a “parse-and-trim” approach and a statistical noisy-channel approach. We introduce the multi-candidate reduction (MCR) framework for multi-document summarization, in which many compressed candidates are generated for each source sentence. These candidates are then selected for inclusion in the final summary based on a combination of static and dynamic features. Evaluations demonstrate that sentence compression is a valuable component of a larger multi-document summarization framework. 相似文献

Psychological science has much to contribute to preK‐12 education because substantial psychological research exists on the processes of learning, teaching, motivation, classroom management, social interaction, communication, and assessment. This article details the psychological science that led to the identification, by the American Psychological Association's Coalition for Psychology in Schools and Education, of the “Top 20 Principles from Psychology for PreK‐12 Teaching and Learning.” Also noted are the major implications for educational practice that follow from the principles. 相似文献

This study sought to advance understanding of the potential long-term consequences of the COVID-19 pandemic for child development by characterizing trajectories of maternal perinatal depression, a common and significant risk factor for adverse child outcomes. Data came from 393 women (86% White, 8% Latina; mean age = 33.51 years) recruited during pregnancy (n = 247; mean gestational age = 22.94 weeks) or during the first year postpartum (n = 146; mean child age = 4.50 months; 55% female). Rates of depression appear elevated, relative to published reports and to a pre-pandemic comparison group (N = 155). This study also provides evidence for subgroups of individuals who differ in their depressive symptom trajectories over the perinatal period. Subgroup membership was related to differences in maternal social support, but not to child birth outcomes. 相似文献

Although parent school councils are the archetypal arrangement for engaging parents in school improvement planning, their effectiveness is negligible when it comes to building parents’ capacity for and confidence in educational decision-making. Using Arnstein’s ladder of citizen participation, this qualitative case study investigated the nature and degree of parents’ participation on six school community councils (SCCs) in Saskatchewan, Canada. Focus groups and interviews with SCC parent members, and school and district leaders were the chief data sources. In most schools, the SCC structure did not dislodge time-honoured barriers that restricted parents’ influence on extracurricular issues. A conceptual examination of participation affords a process-oriented understanding of parent involvement that complements the existing focus on the factors that impact school council effectiveness as an outcome. 相似文献
