Published: July 2021

Quantum emitters in hexagonal boron nitride (hBN) are emerging as bright and robust sources of single photons for applications in quantum optics. In this work we present detailed studies on the limiting factors to achieve Fourier transform limited spectral lines. Specifically, we study phonon dephasing and spectral diffusion of quantum emitters in hBN via resonant excitation spectroscopy at cryogenic temperatures. We show that the linewidths of hBN quantum emitters are phonon broadened, even at 5 K, with typical values of the order of

. While spectral diffusion dominates at increasing pump powers, it can be minimized by working well below saturation excitation power. Our results are important for future utilization of quantum emitters in hBN for quantum interference experiments.
Riset Sesar Aktif Indonesia dan Peranannya dalam Mitigasi Bencana Gempa dan Tsunami
Authors: Natawidjaja Danny Hilman 
Published: July 2021

Wilayah Indonesia yang terletak di antara lempeng tektonik aktif mempunyai aktivitas gempa yang sangat tinggi. Arsitektur seismo-tektonik Indonesia sangat beragam dengan berbagai fenomena gempa sehingga cocok untuk dijadikan laboratoriun alam riset gempa dan tsunami. Namun kondisi ini sekaligus menjadi tantangan besar untuk pembangunan yang aman dari bencana alam. Kontras dengan kebutuhan ini, bidang riset (sesar) gempa dan peranan sentralnya untuk mitigasi bencana belum begitu dipahami di Indonesia, bahkan dikalangan para ahli geologi dan geofisika sekalipun karena hampir seluruh komunitas geosains menekuni sisi ekplorasi dan eksploitasi sumber daya alam. Setelah bencana Aceh tahun 2004, riset gempa dan tsunami mulai mendapat perhatian luas. Baru pada tahun 2007 pemerintah mengeluarkan UU kebencanaan yang menjadi tonggak pertama dalam mewajibkan mitigasi bencana alam. Permasalahan utama yang harus dikerjakan adalah melakukan riset yang sistematis dan komprehensif dalam skala nasional untuk memahami dan mengkaji lebih lanjut berbagai sumber dan potensi bencananya. Karena tanpa pengetahuan dasar yang baik maka usaha mitigasi akan kehilangan arah, tidak efektif dan tidak tepat sasaran. Riset sesar aktif sumber gempa mulai dikembangkan sejak awal tahun 90-an, di wilayah Sumatra, kemudian diteruskan ke Jawa, Nusa Tenggara, Sulawesi, Papua, dan Maluku. Hasil riset memperlihatkan bahwa hampir seluruh wilayah Indonesia terancam bencana gempa (dan tsunami). Hasil riset juga dapat merinci bahwa sistem sesar aktif sumber gempa di Indonesia berbeda-beda karakteristik dan jenis potensi bahayanya dari satu wilayah ke wilayah lainnya. Oleh karena itu, karakter dan potensi sumber gempa dan tsunami yang spesifik untuk setiap wilayah membutuhkan penanganan mitigasi bencana yang juga harus dengan desain spesifik disesuaikan dengan kondisi sumber bencana-nya. Desain tersebut termasuk dalam hal materi pendidikan kebencanaan untuk masyarakat, desain program untuk menyiapkan masyarakat tangguh, dan juga desain sistem monitoring untuk peringatan dini-nya, tidak bisa asal-asalan. Inilah konsep mitigasi berbasis sains dan riset. Data sumber gempa hasil riset sesar aktif sudah dipakai sebagai input untuk membuat peta-peta seismic hazard Indonesia yang dipublikasikan Kementerian PUPR tahun 2010 dan 2017. Peta ini kemudian dipakai untuk membuat SNI Peraturan Konstruksi Tahan Gempa yaitu SNI 1726-2012 dan terakhir SNI 1726-2019. Namun hal ini belum mencakup mitigasi bahaya karena pergerakan di jalur sesar dan bahaya ikutannya. Kearifan lokal yang sering didengung-dengungkan dalam membangun masyarakat tangguh bencana (gempa) pada kenyataannya sudah banyak hilang dari Bumi Nusantara. Padahal sejatinya interaksi antara proses dan kejadian bencana alam dengan manusia Indonesia sudah berlangsung selama ribuan bahkan mungkin puluhan ribu tahun. Untuk menggali kearifan lokal yang hilang diperlukan bantuan riset paleoseismologi, dan arkeo-seismik untuk menemukan kembali fakta kejadian gempa besar di masa lampau yang terekam di alam.

Abstract
Poly(propylene carbonate) (PPC) is an emerging low-cost biodegradable plastic with potential application in many fields. However, compared with polyolefin plastics, the major limitations of PPC are its poor mechanical and thermal properties. Herein, a thermoplastic PPC containing cross-linked networks, one-pot synthesized by the copolymerization of carbon dioxide, propylene oxide, and 4,4ʹ-(hexafluoroisopropylidene) diphthalic anhydride, had excellent thermal and mechanical properties and dimensional stability. The weight-average molecular weight and the polymer yield of the PPC5 were up to 212 kg mol−1 and 104 gpolym gcat
−1, respectively. The 5% thermal weight loss temperature reached 320°C, and it could withstand a tensile force of 52 MPa. This cross-linked PPC has excellent properties and is expected to be used under extreme conditions, as the material can withstand strong tension and will not deform.
Role of dry ozonization of basalt fibers on interfacial properties and fracture toughness of epoxy matrix composites
Authors: Kim Seong-Hwang , Park Sun-Min , Park Soo-Jin 
Published: July 2021

Abstract
The mechanical properties of basalt fiber-reinforced epoxy composites (BFRPs) are significantly dependent on the interfacial adhesion between basalt fibers (BFs) and the epoxy matrix. In this study, we proposed a simple and efficient method for deep and stable penetration of BFs into the epoxy matrix through dry-ozone treatments. To confirm the efficiency of the proposed method, BFRPs were fabricated using two types of composites: untreated BFs and dry-ozonized BFs in varying amounts, and the optimum amount of BFs for all the composites fabricated in this work was 60 wt%. With the addition of this amount of dry-ozonized BFs, the interlaminar shear strength and fracture toughness of the composites were enhanced by 21.2 and 23.2%, respectively, as compared with untreated BFs. The related reinforcing mechanisms were also analyzed, and the enhanced interfacial adhesion was mainly attributed to the mechanical interlocking effect. This approach shows that the dry-ozone treatment of BFs is a simple and efficient method for the preparation of BFRPs with excellent interfacial adhesion, which can be a potential application in the auto parts industry.
Duelling contexts: how action misalignment leads to impoliteness in a courtroom
Authors: Mitchell Nathaniel 
Published: July 2021

Abstract
This paper investigates linguistic and non-linguistic markers of negative evaluations of situated behaviours, termed impoliteness (Culpeper, Jonathan. 2011. Impoliteness: Using language to cause offence. In Drew Paul, Marjorie H. Goodwin, John J. Gumpertz & Deborah Schiffrin (eds.), Studies in interactional linguistics. Cambridge: Cambridge University Press). The paper takes an interactional pragmatic approach to a fixed institutional setting (a courtroom) to investigate how (not why) a series of reprimands and sanctions unfolded. It shows that the key participants, the judge and the defendant, orient to separate interactional cues from their unshared overhearing audiences (their unshared contexts), whilst orienting to each other’s institutional interaction turns (their shared context). This paper suggests that their contexts create competing architectures of intersubjectivity, termed duelling contexts, because the participants are not co-locative (in separate rooms connected through closed circuit TV).
Recent advances in the corpus-based study of ongoing grammatical change in English
Authors: Mair Christian 
Published: July 2021

Abstract
Comparing early and current corpus-based work on ongoing grammatical change in English, the present study argues that progress tends to manifest itself in the more comprehensive and systematic coverage of changes known to be under way rather than in the discovery of genuinely new diachronic processes. As will be shown in two case studies on modal/semi-modal verbs and the progressive, there are three reasons for this. First, corpus research on ongoing change has been helped by increases in the size of available corpora and even more so by better coverage of spoken English. Secondly, researchers have a much wider range of statistical methods to choose from. Thirdly, conceptual advances have been made in theoretical models of change, particularly with regard to the impact of language ideologies and prescriptivism. In the study of ongoing changes, the corpus-based approach remains indispensable because it remedies the errors of impressionistic observation and helps shift attention from a small number of shibboleths important to prescriptivists to the groundswell of grammatical change that generally proceeds below the level of speakers’ conscious awareness.

is a gram-negative oral pathobiont that is associated with severe form of periodontitis. This bacterium has various virulence factors which enables the bacterium to colonize the oral cavity, invade and evade the host defences. Leukotoxin and cytolethal distending toxin are the important virulence factors that causes periodontal destruction. Periodontal infections with seems to be refractory to conventional therapy and systemic antibiotics. Hence, leukotoxin represents an ideal anti-virulence target and inhibition of its immunosuppressive activity would eliminate the colonization advantage provided to the bacteria by the toxin. This review provides a comprehensive update of with an emphasis on its virulence factors leukotoxin and cytolethal distending toxin and its role in periodontal destruction and recent developments in the management.

Postgraduate Internationalisation in Brazil
Authors: McManus Concepta , Baeta Neves Abilio Afonso , Oliveira Cyntia , De Oliveira Castro Henrique 
Published: July 2021

Understanding the current state of the Internationalisation of postgraduate courses in Brazil was essential to serve as a basis for constructing effective policies in funding agencies. It also helps to understand the capacity of the higher education institution to carry out more effective strategic planning and internationalisation plans. This study looks at replies to a Brazilian national funding agency (CAPES) questionnaire on Internationalisation within Higher Education Institutes in Brazil, based on the postgraduate experience. Results showed that Internationalisation is based on mobility with little comprehensive thinking on its role towards academic achievement within the Postgraduate Programs realities, beyond the mobile individual. English language skills need to be improved. While most institutions have offices that treat this theme, they lack an active engagement with the postgraduate programs and strategic planning, seen as vital for almost all institutions. Resources are necessary to build infrastructure and capacitate lecturers and staff to this end.

Written Languaging and Engagement with Written Corrective Feedback: The Results of Reflective Teaching
Authors: Falhasiri Mohammad 
Published: July 2021

For corrective feedback (CF) to contribute to second language (L2) development, some cognitive processes need to be completed. Learners need to notice and comprehend the CF, reflect on and deeply process it, and finally integrate it into their interlanguage (Gass, 1997). Written languaging (WL), which requires learners to explicitly explain to themselves why they have received CF, has been proposed as a technique which can stimulate deep cognitive processing of the written CF. In an effort to improve learners’ writing accuracy, I adopted WL, whereby upon receiving online direct corrections, learners typed their selfexplanations regarding the underlying reasons for their writing mistakes. Then, I engaged in systematic reflection and journaling during a 10-week semester to critically analyze the affordances and limitations of WL. The conclusion, drawn from my perceptions of the usefulness of WL originating from my journal writing, is that WL has the potential to not only facilitate learning for students but also can provide teachers with a rich description of learners’ cognitive and affective engagement with CF. Some recommendations are made for better implementation of this instructional technique.
Pour que la rétroaction corrective (RC) contribue au développement de la langue seconde (L2), des processus cognitifs doivent se produire. Les apprenants doivent remarquer et comprendre la RC, y réfléchir, la traiter profondément et pour finir, l’intégrer dans leur interlangue (Gass, 1997). La mise en langue écrite (MLE), qui exige des apprenants qu’ils s’expliquent à eux-mêmes de façon explicite pourquoi ils ont reçu de la RC, a été proposée comme une technique qui peut stimuler le traitement cognitif profond de la RC écrite. Dans le but d’améliorer la précision de la rédaction des apprenants, j’ai adopté la MLE, où, lorsqu’ils recevaient les corrections directes en ligne, les apprenants tapaient leurs propres explications sur les raisons pour lesquelles ils avaient commis des erreurs écrites. Ensuite, je me suis employé à réfléchir systématiquement et à tenir un journal pendant les 10 semaines que durait le semestre, afin d’analyser de façon critique les opportunités et les limitations de la MLE. La conclusion, tirée de mes perceptions de l’utilité de la MLE puisées dans mon journal, est que la MLE a non seulement le potentiel de faciliter l’apprentissage des apprenants, mais peut aussi fournir aux enseignants une riche description de l’engagement cognitif et affectif des apprenants eu égard à la RC. Des recommandations sont faites pour une meilleure mise en œuvre de cette technique d’enseignement.
