Autobiographic and narrative research has recently grown in stature in the field of social sciences. Inspired by Asian TESOL researchers’ critical analyses of self-stories, this paper attempts to reflect upon the author’s personal history in relation to English and discuss ways in which she can position herself as both an English learner and a non-native English speaker (NNES) teacher. The self-reflection and discussion is followed by an argument for performativity, a notion drawing on poststructuralism to understand language itself and the global spread of English. This paper, itself a performative act conducted by a secondary school teacher, exemplifies the concept. The non-academic schoolteacher’s very act of writing in an academic journal aims to contribute to questioning assumptions underlying the relationship between theory and practice and to reconstituting the academic fields of applied linguistics and TESOL. 近年、自伝的かつ語りを含む研究が社会科学の分野で活発になってきている。本稿では、TESOLを専門とする、あるアジア人研究者が彼女たち自身の物語を素材として実施した批判的分析に着想を得て、英語にまつわる自己の歴史を振り返り、英語学習者としての、またNNESの英語教師としてのポジショナリティをどこに位置づけるのかという問題について議論する。さらに、この批判的自己内省を経て、言語そのもの、あるいは英語という言語の地球規模的広がりを理解するために、ポスト構造主義の概念であるパフォーマティヴィティについて検証する。なお、本稿これ自体がある高校教師によるパフォーマティヴな実践であることに言及しておきたい。研究者ではなく、一高校教師が学術雑誌に投稿することを通じ、理論と実践の関係性の背後にある前提に疑問を投げかけ、その結果、応用言語学やTESOLという学問分野の再構築に貢献できることを希望している。

The global spread of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) that causes COVID-19 has become a source of grave medical and socioeconomic concern to human society. Since its first appearance in the Wuhan region of China in December 2019, the most effective measures of managing the spread of SARS-CoV-2 infection have been social distancing and lockdown of human activity; the level of which has not been seen in our generations. Effective control of the viral infection and COVID-19 will ultimately depend on the development of either a vaccine or therapeutic agents. This article highlights the progresses made so far in these strategies by assessing key targets associated with the viral replication cycle. The key viral proteins and enzymes that could be targeted by new and repurposed drugs are discussed.

BACKGROUND The global spread of the 2019 coronavirus diseases (COVID-19) has caused emotional distress. However, whether auricular vagus nerve acupressure (AVNA) is effective in improving emotional distress under the COVID-19 has not been well-documented. OBJECTIVE To confirm whether AVNA is effective in improving emotional distress under the COVID-19 pandemic. METHODS A smartphone-based online, randomized, controlled trial was designed in four study sites, including Wuhan, Beijing, Shenyang, and Guangzhou of China, from 26 February 2020 to 28 April 2020. Participants were randomly assigned to three times of AVNA (n = 191) or usual care (UC, n = 215) for 14 days. The primary outcome was the response rate, which was the proportion of participants whose Hospital Anxiety and Depression Scale (HADS) score reduced from baseline by ≥ 50%. The assessment was conducted at baseline, 3 days, and 14 days. RESULTS The AVNA group had a markedly higher response rate than the UC group at 3 days (35.6% vs. 24.9%, P = 0.02) and at 14 days (70.7% vs. 60.6%, P = 0.02). The AVNA group showed significantly greater reduction in score of HADS at the two measurement points and BAI at 3 days (P ≤ 0.03), with average respective effect size of 0.217 and 0.195. Participants with AVNA spent less time falling asleep and rated their sleep quality being remarkably higher than those with UC at endpoint. CONCLUSIONS AVNA can be recommended for patients with emotional distress under the current COVID-19 pandemic and other emergent events. CLINICALTRIAL www.chictr.org.cn Identifier: ChiCTR2000030078.

The two main themes contained within the title The Biology of Urban Environments are explored. The initial focus is on urban environments. A discussion of the origins of cities and the global spread of urbanization leads on to a consideration of urban environments in the twenty-first century. In the second section, the focus switches to biology. The scope of the discipline is set out in terms of both the range of sub-disciplines and of biological scales. It is established from this discussion that in this book the topics considered span from genes to ecosystems and will be illustrated by examples of the biology of micro-organisms, plants, and animals. Importantly humans will be included within this consideration: our biology is affected by urban environments. The final part presents the structure of the book.

AbstractThe global spread of the SARS-CoV-2 virus during the early months of 2020 was rapid and exposed vulnerabilities in health systems throughout the world. Obstetric SARS-CoV-2 disease was discovered to be largely asymptomatic carriage but included a small rate of severe disease with rapid decompensation in otherwise healthy women. Higher rates of hospitalization, Intensive Care Unit (ICU) admission and intubation, along with higher infection rates in minority and disadvantaged populations have been documented across regions. The operational gymnastics that occurred daily during the Covid-19 emergency needed to be translated to the obstetrics realm, both inpatient and ambulatory. Resources for adaptation to the public health crisis included workforce flexibility, frequent communication of operational and protocol changes for evaluation and management, and application of innovative ideas to meet the demand.

Enteric fever is a life-threatening systemic febrile disease caused by Salmonella enterica serovars Typhi and Paratyphi (S. Typhi and S. Paratyphi). Unfortunately, the burden of the disease remains high primarily due to the global spread of various drug-resistant Salmonella strains despite continuous advancement in the field. An accurate diagnosis is critical for effective control of the disease. However, enteric fever diagnosis based on clinical presentations is challenging due to overlapping symptoms with other febrile illnesses that are also prevalent in endemic areas. Current laboratory tests display suboptimal sensitivity and specificity, and no diagnostic methods are available for identifying asymptomatic carriers. Several research programs have employed systemic approaches to identify more specific biomarkers for early detection and asymptomatic carrier detection. This review discusses the pros and cons of currently available diagnostic tests for enteric fever, the advancement of research toward improved diagnostic tests, and the challenges of discovering new ideal biomarkers and tests.
