A corpus-based lexical analysis of Chinese medicine research articles.

This is the final version of the article. Available from the publisher via the URL in this record.This study investigates the usefulness of two academic word lists - Coxhead’s (2000) Academic Word List (AWL) and Gardner & Davies’ (2014) Academic Vocabulary List (AVL) - for students of English for Chinese Medical Purposes. The two academic word lists were evaluated in terms of the coverage they achieved in a corpus of Chinese medical research articles (CMRAs) written in English. The AWL was found to cover 10.64% of tokens in the corpus, while the AVL was found to cover 21.17% overall. In both cases, the majority of the coverage was achieved by a relatively small subset of the lexical items on the lists. Analysis of the most frequently used words that are not included in the General Service List, Academic Word List and Academic Vocabulary List in the CMRAs shows that a small number of such words achieve a high level of coverage, suggesting that they should be given a great deal of attention by learners in this discipline. This suggests that a discipline-specific listing would be of great benefit to learners in this discipline. A list of the most prominent 100 off-list lexical items is provided

Novel Precursors for Boron Nanotubes: The Competition of Two-Center and Three-Center Bonding in Boron Sheets

We present a new class of boron sheets, composed of triangular and hexagonal motifs, that are more stable than structures considered to date and thus are likely to be the precursors of boron nanotubes. We describe a simple and clear picture of electronic bonding in boron sheets and highlight the importance of three-center bonding and its competition with two-center bonding, which can also explain the stability of recently discovered boron fullerenes. Our findings call for reconsideration of the literature on boron sheets, nanotubes, and clusters.Comment: 4 pages, 4 figures, 1 tabl

What are the educational needs and experiences of asylum-seeking and refugee children, including those who are unaccompanied, with a particular focus on inclusion? - A literature review

In a context of mass displacement and flows of asylum-seeking and refugee peoples across national borders, the need to respond and attend to the education of asylum-seeking and refugee children is urgent and pressing, though it is not without its challenges. This literature review focuses on the educational experiences of asylum seeking and refugee children, including those who are unaccompanied, with a particular focus on inclusion. It seeks to respond to the following three interconnected questions: 1. What does current educational literature tell us about the educational needs and experiences of asylumseeking and refugee children as they relate to inclusion? 2. What does current educational literature tell us about the educational needs and experiences of unaccompanied asylum-seeking and refugee children as they relate to inclusion? 3. What implications and recommendations can be drawn from existing literature? The review has a particular interest in the needs and experiences of unaccompanied asylum-seeking and refugee children, but recognises that though there is a developing literature specifically on unaccompanied asylum seeking and refugee children (see, for example, Stanley, 2001; Derluyn and Broekaert, 2008; Pastoor, 2015) such needs must be understood and positioned in relation to the wider educational needs and experiences of asylum seeking and refugee children more generally. While other literature reviews on asylum-seeking and refugee children are available (see, for example, Hek, 2005; McBrien, 2005), the present review adds to existing work by: • including an explicit focus on the educational needs and experiences of asylum-seeking and refugee children who are unaccompanied; • providing an up-to-date review of literature which analyses and reports the educational needs and experiences of asylum-seeking and refugee children. The review focuses in particular on post-migration experiences within school settings as they relate to asylum seeking and refugee children’s social inclusion

Inclusive educational provision for newly-arrived unaccompanied asylum-seeking and refugee children: a study in a single school in Kent

Recent migration flows – including those resulting from conflict, persecution and natural disaster – place a responsibility on nations to honour international and humanitarian commitments with respect to refugees. A central part of these commitments is to make provision for the educational needs of asylum-seeking and refugee children, including those whom are unaccompanied. Indeed, education and schooling play a crucial role in the complex relationship between newly-arrived immigrants and their new host communities. In the UK and elsewhere a body of research evidence has developed regarding the post-migration educational needs and experiences of asylum-seeking and refugee children. As we have reported elsewhere (Peterson et al., 2016), such research points to a range of approaches, relationships and practices through which asylum-seeking and refugee children are, and indeed at times are not, included within their new communities, including the school community. The study reported here was conducted in a national and local context of increased recognition (both positive and negative) of the humanitarian plight and presence of asylum-seeking and refugee people and children, including children whom are unaccompanied. The study focused on the approach of a single 11-18 school –Hartsdown Academy – situated in Margate, Kent. Working with Virtual School Kent, the school has developed its existing educational provision to include newly-arrived unaccompanied asylum-seeking and refugee children. The present study is concerned particularly with the perceived and actual social and cultural outcomes and benefits (including any notable challenges and barriers) of the school’s approach to including newly-arrived unaccompanied asylum-seeking and refugee children

Non-adjacent dependency learning in infancy, and its link to language development

To acquire language, infants must learn how to identify words and linguistic structure in speech. Statistical learning has been suggested to assist both of these tasks. However, infants’ capacity to use statistics to discover words and structure together remains unclear. Further, it is not yet known how infants’ statistical learning ability relates to their language development. We trained 17-month-old infants on an artificial language comprising non-adjacent dependencies, and examined their looking times on tasks assessing sensitivity to words and structure using an eye-tracked head-turn-preference paradigm. We measured infants’ vocabulary size using a Communicative Development Inventory (CDI) concurrently and at 19, 21, 24, 25, 27, and 30 months to relate performance to language development. Infants could segment the words from speech, demonstrated by a significant difference in looking times to words versus part-words. Infants’ segmentation performance was significantly related to their vocabulary size (receptive and expressive) both currently, and over time (receptive until 24 months, expressive until 30 months), but was not related to the rate of vocabulary growth. The data also suggest infants may have developed sensitivity to generalised structure, indicating similar statistical learning mechanisms may contribute to the discovery of words and structure in speech, but this was not related to vocabulary size

“I need somebody who knows about feet” a qualitative study investigating the lived experiences of conservative treatment for patients with posterior tibial tendon dysfunction

Background: Posterior tibial tendon dysfunction is a disabling, chronic, progressive tendon condition that detrimentally affects foot, ankle and lower limb function. Research suggests that posterior tibial tendon dysfunction is poorly recognised and difficult to treat. When posterior tibial tendon dysfunction is diagnosed, the clinician is faced with a weak evidence base and guidelines for the common conservative treatments to guide their management. Moreover, there are no current evidence-based guidelines for the conservative management of posterior tibial tendon dysfunction. Emerging research suggests that posterior tibial tendon dysfunction not only has a physical impact on the patient, but it also has psychosocial impact on quality of life. Conservative treatments for posterior tibial tendon dysfunction are generally undertaken during early management. The most common are foot orthoses, exercises, bracing, lifestyle changes and injections. Quantitative evidence supporting conservative treatments for posterior tibial tendon dysfunction in relation to function, pain and patient reported outcome measures are reported in the literature. There is a paucity of qualitative research investigating the psychosocial impact of the common treatments for posterior tibial tendon dysfunction. Interpretative phenomenology is concerned with lived experience which is involves the detailed exploration of experience which is embedded within the social and temporal contexts of the lifeworld of the person. The aim of study research is to investigate the lived experience of conservative treatments for patients who have posterior tibial tendon dysfunction using Interpretative Phenomenological Analysis. Methods: Five participants with posterior tibial tendon dysfunction were purposively recruited from a private podiatry practice and semi-structured interviews were conducted to examine their lived experiences of treatment for posterior tibial tendon dysfunction. The data for this study was collected and analysed using Interpretative Phenomenological Analysis. Results: This research identified three superordinate themes which influenced the lived experience of treatment for these patients (i) adverse experience during the patient journey (ii) treatment burden, and (iii) negative self-concept. Conclusion: This study highlights some of what is anecdotally known about the lived experience of treatment for patients with posterior tibial tendon dysfunction, but has never been studied in a qualitative, methodological manner. This study addresses the gap in the qualitative literature. It reveals novel aspects of the lived experience throughout the patient journey, the detrimental impact of treatment burden, loss and negative self-concept. This evidence is important because it highlights the need for a greater understanding of the psychological and social factors that can influence the lived experience of treatment for this group of patients

Energy versus electron transfer in organic solar cells: a comparison of the photophysics of two indenofluorene: fullerene blend films

In this paper, we compare the photophysics and photovoltaic device performance of two indenofluorene based polymers: poly[2,8-(6,6,12,12-tetraoctylindenofluorene)-co-4,7-(2,1,3-benzothiodiazole] (IF8BT) and poly[2,8-(6,6,12,12-tetraoctylindenofluorene)-co-5,5-(40,70-di-2-thienyl-20,10,30-benzothiodiazole] (IF8TBTT) blended with [6,6]-phenyl C61 butyric acid methyl ester (PCBM). Photovoltaic devices made with IF8TBTT exhibit greatly superior photocurrent generation and photovoltaic efficiency compared to those made with IF8BT. The poor device efficiency of IF8BT/PCBM devices is shown to result from efficient, ultrafast singlet F€orster energy transfer from IF8BT to PCBM, with the resultant PCBM singlet exciton lacking sufficient energy to drive charge photogeneration. The higher photocurrent generation observed for IF8TBTT/PCBM devices is shown to result from IF8TBTT’s relatively weak, red-shifted photoluminescence characteristics, which switches off the polymer to fullerene singlet energy transfer pathway. As a consequence, IF8TBTT singlet excitons are able to drive charge separation at the polymer/fullerene interface, resulting in efficient photocurrent generation. These results are discussed in terms of the impact of donor/acceptor energy transfer upon photophysics and energetics of charge photogeneration in organic photovoltaic\ud devices. The relevance of these results to the design of polymers for organic photovoltaic applications is also discussed, particularly with regard to explaining why highly luminescent polymers developed for organic light emitting diode applications often give relatively poor performance in organic photovoltaic devices

Viral antibody dynamics in a chiropteran host

1. Bats host many viruses that are significant for human and domestic animal health, but the dynamics of these infections in their natural reservoir hosts remain poorly elucidated.<p></p> 2. In these, and other, systems, there is evidence that seasonal life-cycle events drive infection dynamics, directly impacting the risk of exposure to spillover hosts. Understanding these dynamics improves our ability to predict zoonotic spillover from the reservoir hosts.<p></p> 3. To this end, we followed henipavirus antibody levels of >100 individual E. helvum in a closed, captive, breeding population over a 30-month period, using a powerful novel antibody quantitation method.<p></p> 4. We demonstrate the presence of maternal antibodies in this system and accurately determine their longevity. We also present evidence of population-level persistence of viral infection and demonstrate periods of increased horizontal virus transmission associated with the pregnancy/lactation period.<p></p> 5.The novel findings of infection persistence and the effect of pregnancy on viral transmission, as well as an accurate quantitation of chiropteran maternal antiviral antibody half-life, provide fundamental baseline data for the continued study of viral infections in these important reservoir hosts
