The current LiDAR-inertial odometry is prone to cumulative Z-axis error when it runs for a long time. This error can easily lead to the failure to detect the loop-closing in the correct scenario. In this paper, a ground-constrained LiDAR-inertial SLAM is proposed to solve this problem. Reasonable constraints on the ground motion of the mobile robot are incorporated to limit the Z-axis drift error. At the same time, considering the influence of initial positioning error on navigation, a keyframe selection strategy is designed to effectively improve the flatness and accuracy of positioning and the efficiency of loop detection. If GNSS is available, the GNSS factor is added to eliminate the cumulative error of the trajectory. Finally, a large number of experiments are carried out on the self-developed robot platform to verify the effectiveness of the algorithm. The results show that this method can effectively improve location accuracy in outdoor environments, especially in environments of feature degradation and large scale.

Digital evidence is rapidly emerging as a tool for migration authorities in refugee status determination (RSD)—the procedure for determining whether a person meets the criteria for protection as a “refugee.” Its growing popularity may be seen as a response to the relative dearth of “hard” evidence in asylum procedures, where decisions often hinge exclusively on the applicant's personal narrative and assessment of her credibility. In this essay, we critically examine the growing use of digital evidence in RSD by authorities and the human rights concerns that arise from some of these practices. We then move to outline some examples of how digital evidence might also present new opportunities for scholars, practitioners, and asylum seekers themselves, helping to substantiate claims and document underlying inequities in existing RSD practices. In the process, we seek to navigate a balance between the techno-solutionism that hails digital evidence as a panacea and those a priori dismissing digitization as techno-hype and inherently problematic.

The Bell Jar (1963) is a semi-autobiographical novel written by the confessional poet, novelist and short-story writer Sylvia Plath (1932–1963). It has been often cited as a recommended reading within the medical humanities, because of its powerful description of depression and the understanding-by-experience of the related psychiatric treatments. This brief article, primarily directed at the clinically oriented reader, presents a selection of excerpts from The Bell Jar to illustrate the main diagnostic features of clinical depression and the vital role of therapeutic relationship quality in hindering or facilitating treatment outcomes and recovery.

Research on serious mental disorders, particularly psychosis, has revealed highly variable symptom profiles and developmental trajectories prior to illness-onset. As Dante Cicchetti pointed out decades before the term “transdiagnostic” was widely used, the pathways to psychopathology emerge in a system involving equifinality and multifinality. Like most other psychological disorders, psychosis is associated with multiple domains of risk factors, both genetic and environmental, and there are many transdiagnostic developmental pathways that can lead to psychotic syndromes. In this article, we discuss our current understanding of heterogeneity in the etiology of psychosis and its implications for approaches to conceptualizing etiology and research. We highlight the need for examining risk factors at multiple levels and to increase the emphasis on transdiagnostic developmental trajectories as a key variable associated with etiologic subtypes. This will be increasingly feasible now that large, longitudinal datasets are becoming available and researchers have access to more sophisticated analytic tools, such as machine learning, which can identify more homogenous subtypes with the ultimate goal of enhancing options for treatment and preventive intervention.

Le présent article se propose de concevoir l’influence de la notion de légitimité au-delà du rôle lui étant communément attribué en droit international humanitaire (DIH), en s’intéressant particulièrement à la relation entre ce dernier et les causes de la guerre, la nature des acteurs impliqués dans les conflits armés ainsi que les motivations des parties. En remettant notamment en question de l’idée d’une stricte séparation entre jus in bello et jus ad bellum, il est soutenu que les tentatives visant à isoler le DIH de ces questions de légitimité sont à la fois vaines, mais également à rebours de l’évolution et des logiques du régime. Il est en revanche défendu que la notion de légitimité en DIH se manifeste à travers deux modes de légitimation — l’un dérivant du statut, l’autre de la cause — à partir desquels la distribution de droits, devoirs, immunités, privilèges ou encore statuts s’opère et se voit justifiée au sein du régime. Ce faisant, de nombreux discours empruntant au second registre, souvent qualifiés d’aberrations du point de vue du DIH, ou dont la nature juridique est contestée, s’avèrent finalement être des arguments juridiques parfaitement valides et ancrés dans l’évolution et les logiques du DIH.

According to moral encroachers, the moral stakes of a belief partly determine how much evidence we need for the belief to count as knowledge. This view concerns the beliefs of individual believers. In this paper, I argue for a social group version of moral encroachment: dominant groups, such as white people or men, need to have more evidence than the marginalised in order for some of their beliefs to constitute knowledge. I argue for this claim in three steps. First, I spell out the group moral stakes involved – the harms dominant knowers cause the marginalised and the knowledge economy. Second, I show off the theoretical benefits of having the notion of social group moral encroachment at our disposal: it can be an invaluable tool for decolonial and feminist epistemologists if they want to avoid the relativistic ring to their views (a ring that tends to put off many well-wishers). Finally, I start on a positive account of social group moral encroachment by addressing a potential puzzle and responding to objections.

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.
