This study offers a comprehensive bibliometric analysis of artificial intelligence (AI) applications in the field of second language (L2) teaching and applied linguistics, spanning from the early developments in 1995 to 2022. It aims to uncover current trends, prominent themes, and influential authors, documents, and sources. A total of 185 relevant articles published in Social Sciences Citation Index (SSCI) indexed journals were analyzed using the VOSviewer bibliometric software tool. Our investigation reveals a highly multidisciplinary and interconnected field, with four main clusters identified: AI, natural language processing (NLP), robot-assisted language learning, and chatbots. Notable themes include the increasing use of intelligent tutoring systems, the importance of syntactic complexity and vocabulary in L2 learning, and the exploration of robots and gamification in language education. The study also highlights the potential of NLP and AI technologies to enhance personalized feedback and instruction for language learners. The findings emphasize the growing interest in AI applications in L2 teaching and applied linguistics, as well as the need for continued research to advance the field and improve language instruction and assessment. By providing a quantitative and rigorous overview of the literature, this study contributes valuable insights into the current state of research in AI-assisted L2 teaching and applied linguistics and identifies key areas for future exploration and development.

Conceptually rooted in the efforts to ban indiscriminate weapons and both their immediate and long-term effects, humanitarian mine action and humanitarian disarmament operations have developed significantly since 1988, when the United Nations first took on work on mine action operations for the protection and benefit of local communities. A large part of those operations has been carried out by humanitarian disarmament NGOs such as the Mines Advisory Group (MAG), one of the first organizations to be established on this issue. Drawing on MAG's experience and perspective, this article explores how the humanitarian principles apply to humanitarian disarmament operations. The aim of the article is to show that as an operator on the humanitarian–development nexus, MAG considers the four humanitarian principles as a critical and necessary part of its reference framework due to the influence of the humanitarian disarmament framework, even when operating in the development space. All in all, the case of humanitarian disarmament and MAG's experience are good examples to illustrate where the humanitarian horizon is extended because of long-terms serious needs, and that humanitarian principles remain essential to keep the focus on the needs of affected populations.

This paper is concerned with the velarized lateral [ɫ] as a possible realization of the lateral phoneme /l/ in the rural Central Bavarian base dialects of German in Austria. So far, velarized laterals in Austrian German have mainly been described as a socially marked realization of /l/ in Vienna. However, descriptions of Austrian dialects mostly lack detailed acoustic analyses. Therefore, we analyzed the first two formants of alveolar laterals from dialect speakers in seventeen locations around Vienna that fall into the Central and South Central Bavarian dialect areas. Recordings were taken from the ‘German in Austria’ Corpus, from four speakers per location (two old, two young, each one male, one female), with thirty-two items per speaker with laterals in word-initial and twenty-two in word-final position. We asked whether the degree of velarization as measured by the difference between F2 and F1 (the smaller the more velarized) depends on this linguistic factor of position in the word – as has been shown for other Germanic languages – or social factors including the recording location’s distance from Vienna, age and gender of the speakers. Results showed that velarization was most frequently but not exclusively found in the Eastern region closest to Vienna (Central Bavarian dialects). Non-velarized and velarized laterals tended towards a complementary distribution in initial versus final word position and male speakers showed more velarization overall. Specifically, old speakers in locations close to Vienna tended towards more velarization in word-initial position compared to other regions, matching descriptions of Viennese dialect.

The increasing integration of digital technologies in business processes calls for a deeper understanding of their impact on business model efficiency. This study explores how digital alignment, composed by strategic decision support and operational support, affects business model efficiency, while also examining the extent to which strategic flexibility moderates this relationship. To test the proposed hypotheses, we adopt a quantitative approach on a sample of Italian small and medium-sized enterprises in the manufacturing industry. In particular, a regression analysis, complemented by a necessary condition analysis, is performed. We find that digital alignment, both in terms of strategic decision support and operational support, fosters business model efficiency. Strategic flexibility strengthens the relationship between strategic decision support and business model efficiency. To the best of our knowledge, this study is the first to operationalise digital alignment as composed of strategic decision support and operational support. Accordingly, this study contributes to the extant literature on digital alignment and business models.

This article focuses on Watchlist, a new play written by Alex Vickery-Howe, placing it in a context of contemporary Australian political writing for the stage which sees playwrights, such as Stephen Sewell and Suzie Miller, adopt an international outlook in order to tell stories of activism. By creating nuanced characters and engaging with the popular, these playwrights are inspiring activism in their audiences in engaging and challenging ways, arguing that what is deemed off-limits should not be left off-stage.

In this work we prove that every shift of finite type (SFT), sofic shift, and strongly irreducible shift on locally finite groups has strong dynamical properties. These properties include that every sofic shift is an SFT, every SFT is strongly irreducible, every strongly irreducible shift is an SFT, every SFT is entropy minimal, and every SFT has a unique measure of maximal entropy, among others. In addition, we show that if every SFT on a group is strongly irreducible, or if every sofic shift is an SFT, then the group must be locally finite, and this extends to all of the properties we explore. These results are collected in two main theorems which characterize the local finiteness of groups by purely dynamical properties. In pursuit of these results, we present a formal construction of free extension shifts on a group G, which takes a shift on a subgroup H of G, and naturally extends it to a shift on all of G.

The Soviet campaign in support of the Democratic Republic of Vietnam in the Vietnam War saturated Soviet public culture in the late 1960s and early 1970s. It was the longest solidarity action in Soviet history and the first to reach mass television audiences. This article examines the production and reception of a televised documentary film about the Vietnam War made by Konstantin Simonov – a celebrity writer who played a crucial role in Soviet culture during World War II, and then, in the post-war period, in the struggle to come to terms with terrible truths about Stalinism and the chaos and trauma that war had rendered. Simonov's film presented the Vietnam War in lyrical rather than analytical terms, calling upon viewers to draw connections between the suffering of the Vietnamese and the Soviet wartime experience and to enact their solidarity with the Vietnamese in terms of feeling. The film proposes a solidarity of pain and an understanding of war and wartime suffering as elemental and overwhelming. In dozens of letters to Simonov, we find an understanding and appreciation of this vision, which decentres Vietnam and instead sends viewers on a journey back to Soviet history and trauma.

The growing literature on Covid-19 and theatre has demonstrated how the pandemic has intensified gendered precarities in theatrical labour.1 However, the pandemic has also provided feminist theatre makers with unexpected or unlikely resources, albeit with limitations. The Istanbul Municipal Theatre's (İstanbul Büyükşehir Belediyesi Şehir Tiyatroları or İBBŞT) production of Melek that premiered in 2020 is an indicative example of such rare and largely invisible cases of pandemic theatre. Critically engaging with the archives and repertoires of tuberculosis (TB) melodrama and the Turkish lives of the genre, Melek conducts an experiential mapping of the performativity of death and the porous borders between everyday performance and artistic performance. The production offered independent feminist theatre practitioners, who otherwise maintain a precarious existence in Turkey's theatre world, access to new spaces, resources and audiences. Combining archival with ethnographic research, I will demonstrate how, in the case of Melek, the intersections between actual and fictive viral contagion – what I define as viral interstitiality – constitute inclusive economies amidst the Covid-19 pandemic. In somatics, the interstitial is theorized and enacted as suspensions of static schisms that shape relational empowerment.2 Drawing upon this grasp of the interstitial as connective thresholds, viral interstitiality sheds light on the practices and the economies of care that emerge from the porous dynamism between the viral and the theatrical.

One fifth of Earth's volcanoes are covered by snow or ice and many have active geothermal systems that interact with the overlying ice. These glaciovolcanic interactions can melt voids into glaciers, and are subject to controls exerted by ice dynamics and geothermal heat output. Glaciovolcanic voids have been observed to form prior to volcanic eruptions, which raised concerns when such features were discovered within Job Glacier on Qw̓elqw̓elústen (Mount Meager Volcanic Complex), British Columbia, Canada. In this study we model the formation, evolution, and steady-state morphology of glaciovolcanic voids using analytical and numerical models. Analytical steady-state void geometries show cave height limited to one quarter of the ice thickness, while numerical model results suggest the void height h scales with ice thickness H and geothermal heat flux $\dot {Q}$ as $h/H = a H^b \dot {Q}^c$, with exponents b = −n/2 and c = 1/2 where n is the creep exponent. Applying this scaling to the glaciovolcanic voids within Job Glacier suggests the potential for total geothermal heat flux in excess of 10 MW. Our results show that relative changes in ice thickness are more influential in glaciovolcanic void formation and evolution than relative changes in geothermal heat flux.

To safeguard peace in multi-ethnic countries, scholars and practitioners recommend territorial autonomy. However, there is limited cross-national research on how autonomy affects subnational ethnic conflict, and increasing concern that it redirects ethnic violence from the national to the subnational level. Addressing this gap, I argue that autonomy generates tensions over subnational government control and the distribution of local economic goods. However, whether these turn violent depends on ethnic representation in the central government. If groups are unequally represented, violent escalation is more likely due to information and commitment problems and subnational majoritarianism. To test these arguments, I provide new time-variant data on subnational boundaries, territorial autonomy, and ethnically attributed violence. I conduct a systematic analysis of all multi-ethnic countries between 1989 and 2019, instrumental variable analyses, and tests of my argument’s intermediate implications. My findings underline the importance of complementing autonomy with inclusive central governments to attenuate the risks of subnational violence.

The history of Soviet “rights defenders” is seemingly well known. Emerging in the 1960s in response to fears of a creeping re-Stalinization, the rights movement was part of the broader dissident milieu that coalesced in the Khrushchev and Brezhnev eras. Drawing on new documents from the Ukrainian KGB, this article broadens the canon of what we consider “Soviet rights talk” by focusing on a group completely ignored in the existing history of Soviet rights defenders: African students. As the article demonstrates, Soviet citizens were not the only people to draw on a discursive repertoire of civil and universal rights to articulate their demands against the Soviet state. By closely examining the letters and petitions activists produced, it becomes clear that African students’ language of rights grew alongside and, in many respects, pre-empted the Soviet rights movement. The article concludes by considering why, despite sharing the same discursive and physical spaces, neither African nor Soviet rights defenders succeeded in building bridges between their respective islands of protest. Examining this failure to build meaningful solidarities demonstrates the value of pursuing the social history of internationalism; it is only in the banality of the everyday that the capacity for Soviet internationalism to create unanticipated frictions and conflicts reveals itself.

Excluding children with Shiga toxin-producing Escherichia coli (STEC) from childcare until microbiologically clear of the pathogen, disrupts families, education, and earnings. Since PCR introduction, non-O157 STEC serotype detections in England have increased. We examined shedding duration by serotype and transmission risk, to guide exclusion advice. We investigated STEC cases aged <6 years, residing in England and attending childcare, with diarrhoea onset or sample date from 31 March 2018 to 30 March 2022. Duration of shedding was the interval between date of onset or date first positive specimen and earliest available negative specimen date. Transmission risk was estimated from proportions with secondary cases in settings attended by infectious cases. There were 367 cases (STEC O157 n = 243, 66.2%; STEC non-O157 n = 124, 33.8%). Median shedding duration was 32 days (IQR 20–44) with no significant difference between O157 and non-O157; 2% (n = 6) of cases shed for ≥100 days. Duration of shedding was reduced by 17% (95% CI 4–29) among cases reporting bloody diarrhoea. Sixteen settings underwent screening; four had secondary cases (close contacts’ secondary transmission rate = 13%). Shedding duration estimates were consistent with previous studies (median 31 days, IQR 17–41). Findings do not warrant guidance changes regarding exclusion and supervised return of prolonged shedders, despite serotype changes.
