论文摘要中的主位推进模式探讨

主位推进模式是语类分析的一个重要内容。论文摘要的主位推进模式主要可分为主位同一型，延续型、述位同一型、交叉型四种，通过对《应用语言学》杂志中任选的15篇论文摘要的主位推进模式的分析，可以发现这种语类基本的主位推进模式选择趋向及其对句际语义的影响。     

To Read or Not to Read: A Qualitative Study of Students’ Justifications for Document Selection in Task-Oriented Reading

When navigating through the vast amount of information that we encounter in our everyday lives, we constantly make decisions concerning what information to read more closely and what information to disregard. Consideration of the relevance and trustworthiness of information sources facilitates those decisions. In the present study, we interviewed 25 upper-secondary students after they had selected documents to use in completing a task, and we asked them to justify their selections. A qualitative analysis of the interview data showed that students’ justifications could be related to (1) content relevance, (2) source features, and (3) prior topic knowledge. The results demonstrate that students are able to evaluate content relevance and source features as part of their document selection strategies but that perceived prior knowledge seems to influence both selections and justifications.     

语篇中指称选择的认知语用解释

叙述语篇中的指称选择主要受到三个因素的影响：指称距离，指称对象是否引起歧义，指称对象与话题焦点的关系。这三个因素归根结底可以从心理学方面得到解释。人类的记忆系统和认知特点决定了人类对指称选择的认知加工方式。     

Off with a theme: Emergent curriculum in action

Early childhood teachers can plan developmentally appropriate classrooms through a fusion of thematic and emergent curriculum approaches. Ernie, a preschool teacher/university professor working in a campus laboratory setting, designed and implemented a space theme which was relevant to young children, allowed them many opportunities to demonstrate their knowledge and skills and expand upon them in significant ways, and incorporated a variety of materials and resources. Overall, the use of this theme reflected the initial and emergent interests of both the teachers and children, as they interacted in the social environment.

The publication fate of abstracts presented at the Medical Library Association conferences

Objective:We sought to determine how many abstracts presented at the 2012 and 2014 Medical Library Association (MLA) annual conferences were later published as full-text journal articles and which features of the abstract and first author influence the likelihood of future publication. To do so, we replicated a previous study on MLA conference abstracts presented in 2002 and 2003. The secondary objective was to compare the publication rates between the prior and current study.Methods:Presentations and posters delivered at the 2012 and 2014 MLA meetings were coded to identify factors associated with publication. Postconference publication of abstracts as journal articles was determined using a literature search and survey sent to first authors. Chi-squared tests were used to assess differences in the publication rate, and logistic regression was used to assess the influence of abstract factors on publication.Results:The combined publication rate for the 2012 and 2014 meetings was 21.8% (137/628 abstracts), which is a statistically significant decrease compared to the previously reported rate for 2002 and 2003 (27.6%, 122/442 abstracts). The odds that an abstract would later be published as a journal article increased if the abstract was multi-institutional or if it was research, specifically surveys or mixed methods research.Conclusions:The lower publication rate of MLA conference abstracts may be due to an increased number of program or nonresearch abstracts that were accepted or a more competitive peer review process for journals. MLA could increase the publication rate by encouraging and enabling multi-institutional research projects among its members.     

Plan and generate: Explicit and implicit variational augmentation for multi-document summarization of scientific articles

Multi-Document Summarization of Scientific articles (MDSS) is a challenging task that aims to generate concise and informative summaries for multiple scientific articles on a particular topic. However, despite recent advances in abstractive models for MDSS, grammatical correctness and contextual coherence remain challenging issues. In this paper, we introduce EDITSum, a novel abstractive MDSS model that leverages sentence-level planning to guide summary generation. Our model incorporates neural topic model information as explicit guidance and sequential latent variables information as implicit guidance under a variational framework. We propose a hierarchical decoding strategy that generates the sentence-level planning by a sentence decoder and then generates the final summary conditioned on the planning by a word decoder. Experimental results show that our model outperforms previous state-of-the-art models by a significant margin on ROUGE-1 and ROUGE-L metrics. Ablation studies demonstrate the effectiveness of the individual modules proposed in our model, and human evaluations provide strong evidence that our model generates more coherent and error-free summaries. Our work highlights the importance of high-level planning in addressing intra-sentence errors and inter-sentence incoherence issues in MDSS.
