Historical discourse is a valuable contribution to the field of educational discourse analysis from a functional approach. Drawing heavily on systemic functional linguistics (SFL), in particular the work of Michael Halliday and Jim Martin, Coffin elucidates how to analyze, interpret, and evaluate historical discourse and compose good historical prose. Based on quantitative research, Coffin argues for the vital role of language in disciplinary teaching and learning. Historical discourse is composed of 8 chapters, plus an appendix, glossary, and index. Coffin starts with ten questions addressing the aim, approach, scope, and structure of the book. Chapter 2 presents SFL theories that understand language as a "meaning potential" which realizes particular social functions. Following the discussion of genre (the structuring of texts), Coffin concentrates on the three register variables of social context-field, tenor, and mode-and how they are related to the ideational, interpersonal and textual metafunctions of language. Chapters 3 and 4 are devoted to the elaboration of the three historical genre types, recording, explaining, and arguing, and subgenres of each. Each type serves different social purposes and therefore has different variable register features, realized by different lexicogrammatical resources. Coffin stresses that language use is a social act and a process of resource choosing. Text structures play important roles in history learning. According to Coffin, each (sub-)genre represents a perspective on the past, and the process of learning is one of acquiring linguistic strategies in construing history along a continuum from relatively personal and objective (recording) to public and more subjective (arguing). Chapters 5, 6 and 7 concentrate respectively on three central factors of historical discourse: time, cause-and-effect, and evaluation, all of which are closely related to the historical genre types. That is, each genre chooses among potential temporal, causal, and appraisal resources to realize its social functions. Coffin approaches temporal resources by establishing categories and analyzing vocabulary and grammar features of each category. Her corpus-based study illustrates that the linguistic resource deployment of time varies across historical genres. Coffin therefore argues that in learning historical time, students move from a chronological arrangement (recording) to complicated conceptual reshaping (explaining, arguing). It is a process during which students learn to manage linguistic strategies for representing time that are appropriate for different text types. Following a similar structure, in chapter 6 Coffin explores the linguistic resources for causation in historical discourses. History students develop their ability to produce recording, in which external connection dominates, before upgrading to the explanation and then to the arguing genres, in which internal and abstract reasoning is in control. Chapter 7 centers on how to recognize and employ the evaluative resources of language i...
Rationale:Madelung disease (MD), a rarely reported disease, also known as benign symmetric lipomatosis, a disorder resulting from alcoholic abuse. It's largely under-recognized and under-reported, possibly because of unawareness of the condition by physicians.Patient concerns:A 45-year-old Chinese man presented with intermittent fatigue and abdominal distension and progressive bilateral breast enlargement. He has been a heavy drinker for ten years before onset of the disease with an average daily alcohol intake of more than 120 g/day.Diagnosis:Due to the patient's symptoms, laboratory test results, radiographic findings, he was diagnosed with MD.Interventions:We treated him with abstinence from alcohol and supportive therapy.Outcomes:The patient is now in stable condition, with improvement in symptoms during follow-up.Lessons:Doctors, confronted with progressive bilateral breast enlargement in a patient with alcoholic liver disease, should be aware of the underreported MD. Recognition of this syndrome could help doctors establish diagnosis and emphasize the importance of alcohol abstinence as the mainstay of management.
Syringa oblata Lindl. is a popular ornamental shrub with aroma compounds. Here, we sequenced and assembled the complete chloroplast genome of S. oblata . The complete chloroplast genome of S. oblata is 155,648 bp in length, containing a pair of inverted repeated (IRa and IRb) region of 25,732 bp that are separated by a large single copy (LSC) region of 86,247 bp, and a small single copy (SSC) region of 17,937 bp. A total of 132 functional genes were annotated, including 88 protein-coding genes, 36 tRNA genes, and eight rRNA genes. The Neighbour-joining phylogenetic tree based on complete chloroplast genomes suggested that S. oblata is most closely related to S. vulgaris .
The purpose of the present paper is to offer a state-of-the-art review on the topic of Systemic Functional Linguistics (SFL) and its theoretical and practical implications on the field of language education, being the former widely recognized due to its potentiality to encourage both reflection and action for the participants involved. Recent empirical studies were located and thoroughly reviewed, which shed light on the three most researched areas including text analysis and literacy intervention, classroom discourse, and the language teaching and learning processes. As a final remark and taking into account the literature analysis, some prospective studies are briefly proposed.
