Published: November 2022

ObjectivesThe effective implementation of a fast-changing healthcare delivery innovation, such as robotic-assisted surgery (RAS), into a healthcare system, can be affected (both positively and negatively) by external contextual factors. As part of a wider project investigating ways to optimise the implementation of RAS, this qualitative study aimed to uncover current issues of RAS and predictions about the future of robotic surgery. We refer to ‘current issues’ as the topical and salient challenges and opportunities related to the introduction of RAS in the UK healthcare system, from the perspectives of key stakeholders involved in the delivery and implementation of RAS.DesignSemi-structured interviews and focus groups were conducted. A thematic analysis was conducted to summarise salient issues that were articulated by the participants.Setting and participantsThe interview sample (n=35) comprised surgeons, wider theatre staff and other relevant personnel involved in the introduction and delivery of RAS services across the UK, including service managers and policymakers/commissioners. Two focus groups were also conducted with surgical trainees (n=7) and members of the public (n=8), respectively.ResultsThe results revealed a largely positive attitude towards the introduction of RAS technology and an expectation of continued rapid expansion. Areas perceived to be particularly pertinent and requiring ongoing attention were also highlighted, including the need to achieve improved quality control, expertise quantification and training issues and the need to educate the public. Issues of centralisation, service organisation and equity of access were also emphasised.ConclusionsOur study has highlighted a range of issues perceived to be particularly pertinent to the current and future provision of RAS which should be addressed. The areas outlined can enable healthcare managers and surgeons to plan for the adoption and/or expansion of RAS services.
Majorana propagator on de Sitter space
Authors: Prokopec Tomislav , Unnithan Vishnu Hari 
Published: November 2022

AbstractWe study the dynamics of Majorana fermions in an expanding de Sitter space and to that aim, by making use of the method of mode sums, we construct the vacuum Feynman propagator for Majorana fermions in de Sitter space. The Majorana condition implies nontrivial identities for the mode functions, which we carefully implement. We note that, under charge conjugation, the propagator transforms to minus itself, but do not discuss in detail the topological implications of this observation. We construct the propagator for a general complex mass and find that it is identical to the corresponding Dirac propagator, meaning that the coupling of fermions to the classical de Sitter gravitational background does not violate charge symmetry, i.e. it respects the Majorana condition. The complex mass propagator differs from its real mass counterpart in that the usual positive and negative energy projectors acquire a chiral rotation which depends on the phase of the mass term. We use our propagator to calculate the one-loop effective action for Majorana fermions, and find that it differs from that of Dirac fermions by a factor of 1/2, which accounts for the reduced number of degrees of freedom of the Majorana particle. Finally, we derive the Majorana and Dirac propagators for mixing n fermionic flavors and show that the number of CP-violating phases for Dirac fermions exceeds that of the Majorana fermions by $${n\left( n-1\right) }/{2}$$

Behold the Once and Future Me: Online Identity After the End of a Romantic Relationship
Authors: Pinter Anthony T. , Brubaker Jed R. 
Published: November 2022

After a romantic relationship ends, individuals are left to deal with the digital remnants of the relationship. These possessions and connections pose difficulties for users -- they are identity markers of an identity that one may no longer want legible to their online audiences. Further, they can cause upsetting moments that might impede moving on from the break-up.Through interviews with 11 women who had had a recent break-up, this empirical study examined how people managed their online identity after their break-up. We found that people took different actions towards their possessions and connections in service of creating a post-break-up identity. Using Brubaker & Hayes's (2011) representational framework, we find users attempting to deal with connections as if they were possessions, creating tensions that our current systems are ill-suited to address. Turning to Hogan's (2010) framework of the online identity 'exhibition', we see users creating exhibitions for an audience of one -- themselves -- while also making decisions about who is allowed to see their public-facing exhibitions. We conclude by arguing that existing tools are ill-designed to support competing desires to present authentic past and future online identities and offer design suggestions for consideration.
"I needed to solve their overwhelmness": How System Administration Work was Affected by COVID-19
Authors: Kaur Mannat , Parkin Simon , Janssen Marijn , Fiebig Tobias 
Published: November 2022

The ongoing global COVID-19 pandemic made working from home -- wherever working remotely is possible -- the norm for what had previously been office-based jobs across the world. This change in how we work created a challenging situation for system administrators (sysadmins), as they are the ones building and maintaining the digital infrastructure our world relies on.
In this paper, we examine how system administration work changed early in the pandemic from sysadmins' personal perspectives, through semi-structured interviews and thematic analysis. We find that sysadmins faced a two-sided crisis: While sysadmins' own work environment changed, they also had to react to the new situation and facilitate stable options to work online for themselves and their colleagues, supporting their users in adapting to the crisis. This finding embeds into earlier work on the connection between IT (security) work and the notion of 'care', where we substantiate these earlier findings with results from a repeatable method grounded in coordination theory.
Furthermore, while we find that sysadmins perceived no major changes in the way they work, by consecutively probing our interviewees, we find that they did experience several counter-intuitive effects on their work. This includes that while day-to-day communication became inherently more difficult, other tasks were streamlined by the remote working format and were seen as having become easier. Finally, by structuring our results according to a model of coordination and communication, we identify changes in sysadmins' coordination patterns. From these we derive recommendations for how system administration work can be coordinated, ranging beyond the immediate pandemic response and the transition to any 'new normal' way of working.
Open Source Software Sustainability: Combining Institutional Analysis and Socio-Technical Networks

Published: November 2022

Sustainable Open Source Software (OSS) forms much of the fabric of our digital society, especially successful and sustainable ones. But many OSS projects do not become sustainable, resulting in abandonment and even risks for the world's digital infrastructure. Prior work has looked at the reasons for this mainly from two very different perspectives. In software engineering, the focus has been on understanding success and sustainability from the socio-technical perspective: the OSS programmers' day-to-day activities and the artifacts they create. In institutional analysis, on the other hand, emphasis has been on institutional designs (e.g., policies, rules, and norms) that structure project governance. Even though each is necessary for a comprehensive understanding of OSS projects, the connection and interaction between the two approaches have been barely explored.
In this paper, we make the first effort toward understanding OSS project sustainability using a dual-view analysis, by combining institutional analysis with socio-technical systems analysis. In particular, we (i) use linguistic approaches to extract institutional rules and norms from OSS contributors' communications to represent the evolution of their governance systems, and (ii) construct socio-technical networks based on longitudinal collaboration records to represent each project's organizational structure. We combined the two methods and applied them to a dataset of developer digital traces from 253 nascent OSS projects within the Apache Software Foundation (ASF) incubator. We find that the socio-technical and institutional features relate to each other, and provide complimentary views into the progress of the ASF's OSS projects. Refining these combined analyses can help provide a more precise understanding of the synchronization between the evolution of institutional governance and organizational structure.
Paying Attention to the Algorithm Behind the Curtain: Bringing Transparency to YouTube's Demonetization Algorithms

Published: November 2022

YouTube has long been a top-choice destination for independent video content creators to share their work. A large part of YouTube's appeal is owed to its practice of sharing advertising revenue with qualifying content creators through the YouTube Partner Program (YPP). In recent years, changes to the monetization policies and the introduction of algorithmic systems for making monetization decisions have been a source of controversy and tension between content creators and the platform. There have been numerous accusations suggesting that the underlying monetization algorithms engage in preferential treatment of larger channels and effectively censor minority voices by demonetizing their content.
In this paper, we conduct a measurement of the YouTube monetization algorithms. We begin by measuring the incidence rates of different monetization decisions and the time taken to reach them. Next, we analyze the relationships between video content, channel popularity and these decisions. Finally, we explore the relationship between demonetization and a channel's view growth rate. Taken all together, our work suggests that demonetization after a video is publicly listed is not a common occurrence, the characteristics of the process are associated with channel size and (in unexplainable ways) video topic, and demonetization appears to have a harsh influence on the growth rate of smaller channels. We also highlight the challenges associated with conducting large-scale algorithm audits such as ours and make an argument for more transparency in algorithmic decision-making.

A new approach to online discussion, which situates student discussions in the margins of the course content, can enhance student engagement with course materials. However, in high-enrollment classes, the large number of comments can overwhelm and intimidate students. Some become frustrated by the volume of potential online interactions and by a perceived lack of immediate relevance to their studies. Likewise, instructors are disappointed when outstanding discussions, that they deem valuable for all to see, get lost in the clutter.
To address these challenges, we propose visual spotlighting mechanisms for increasing the saliency of selected comments. We piloted and deployed multiple designs in two high-enrollment biology courses at a large public university in the United States. Interviews, surveys, and a controlled experiment show that spotlighting relevant comments in heavily annotated texts positively affects students' engagement, measured in terms of their attention to comments, and their reported sense of validation and pride. Students also reported their preferences for certain spotlighting designs.
Life post-death: Colonization of a bat carcass by Microcerella halli (Engel, 1931) (Diptera: Sarcophagidae) in a Neotropical cave
Authors: Vasconcelos Simão Dias , Barbier Eder , Barbosa Taciano Moura 
Published: November 2022

Caves are habitats characterized by low light or total darkness, whose fauna is largely composed of animals that adapt to dark environments, such as bats and many arthropods. Here, we present the first record of bat carcass colonization by Diptera larvae in a cave in the Neotropics. Twenty-one adult specimens of Microcerella halli (Sarcophagidae), seven males and 14 females, emerged from larvae collected in a carcass of Pteronotus gymnonotus (Mormoopidae) found in a twilight zone, about 15 m from the cave entrance. The mean time between carcass collection and adult emergence was 17.99 ± 0.44 days. As colonization by M. halli only occurs after death, we estimated the mean duration of the pupal stage – by recording daily pupation and emergence data – and attempted a preliminary estimate of the post-mortem interval, which indicated that larviposition occurred at least 24 h before carcass collection. Furthermore, we discussed the fact that M. halli females can find and colonize carcasses in low light environments, reinforcing the forensic potential of the species.
Augustus, Advisors and the Senate
Authors: Lindholmer Mads Ortving 
Published: November 2022

Abstract
Cassius Dio’s narrative of Augustus’ reign is fundamental to our understanding of this period. This article will focus on D.C. 55.34.1. After a lacuna, the text reads: ‘… however, declare his opinion among the first, but among the last, his purpose being that all might be permitted to form their views independently’. It has been almost universally assumed for two centuries that this describes Augustus’ interaction with the senators but, through a comparison with Dio’s narrative of Tiberius, I will argue that 55.34.1 actually describes Augustus’ interaction with his advisors. Given the paucity of evidence about Augustus’ interaction with these two bodies, this correction has wide consequences. It also has consequences for research on Dio’s view of Augustus and the ideal monarch as well as scholarship on Dio more broadly.
‘Hybridity by Design’: Between Liberal Norms and Illiberal Peace in Turkey
Authors: Dilek Esra 
Published: November 2022

Abstract
This article investigates the interplay between liberal norms, hybridity, and illiberal peace by proposing ‘hybridity by design’ as a framework for understanding domestic agency of political actors in ‘homegrown’ peace processes. Hybridity by design refers to strategies used in peace processes that are not guided by external third parties for selectively adopting norms and practices associated with the liberal peace model while maintaining an illiberal peacemaking approach. The study focuses on the case of Turkey’s recent experience in peacemaking regarding the Kurdish conflict in two periods. First, the 2009–2015 period is analyzed as a ‘homegrown’ peace process during which ‘hybridity by design’ was the primary strategy used by the government to promote peacemaking combining liberal and illiberal norms and practices. In the post-2015 period, the government emphasized the ‘authentic’ aspects of the Kurdish issue, adopting a friend/enemy discourse, delegitimizing opponents, and rejecting negotiations as a means for solving the conflict.
Trans Auntologies
Authors: Fournier Mat 
Published: November 2022

Abstract
This article reads The Second Sex from the perspective of transmasculinity, using gender dysphoria as a critical approach. Following the threads of an intergenerational history of feminist and queer thinkers, the author is led to examine the particular position of trans men regarding feminism. How does one acknowledge that the category of woman is rooted in oppression without failing to support those who align with it? The true legacy of The Second Sex is a feminist transmasculine ethics.
Masculinity as an Impasse
Authors: Garcia Manon 
Published: November 2022

Abstract
The Second Sex can be read as a compelling philosophical exploration of masculinity. Beauvoir proposes to understand masculinity as a situation. It is an impasse as men are stuck in a position where they seek recognition from women, but they construct women in such a way that the recognition women can give them is incomplete and unsatisfying. This understanding of masculinity is crucial for Beauvoir’s emancipatory agenda and suggests that men have nonaltruistic reasons to take part in feminist movements.
Un existentialisme transatlantique
Authors: Provost Mickaëlle 
Published: November 2022

Résumé
En proposant une lecture intertextuelle de la philosophie de Simone de Beauvoir, cet article étudie la possibilité d’un « existentialisme transatlantique ». Y sont analysés le récit proposé par Beauvoir dans L’Amérique au jour le jour et la manière dont la conceptualisation phénoménologique beauvoirienne du racisme fait écho à la pensée de Richard Wright, mais aussi à celles de W.E.B. Du Bois et de Frantz Fanon. La mise au jour de ces parentés théoriques permet d’éclairer les différences et les conflits entre des vécus distincts d’oppression.

Authors: Lima Fogaca Janaina , Lee Saemi , Joseph Courtney , Clifford Dawn E , Papini Natalie , Lee Jonathan S 
Published: November 2022

Introduction: Peer-led health coaching is a realistic and sustainable way to support health behaviour change on university campuses. Motivational Interviewing (MI) is an effective framework to guide behaviour change conversations in peer health coaching sessions. However, research on the perceptions of peer coaches who provide health coaching using MI is scarce. Objective: The aims of this study were to examine (1) university peer health coaches’ experiences as peer educators after participating in the training and implementation of MI; and (2) university peer health coaches’ supervision experiences as they learn to use MI for health coaching. Design: Cross-sectional in-depth qualitative study using Interpretative Phenomenological Analysis (IPA). Setting: Peer health coaching programme in a mid-sized southwestern US university. Method: Five peer health coaches were interviewed about their training, implementation and supervision of using MI in a university health coaching programme. IPA was used to analyse the findings. Results: We identified four main themes: (1) learning MI, (2) using MI, (3) challenges of time and availability and (4) supervision and peer support. Results illustrated the developmental processes peer health coaches perceive as they develop their MI skills. Individual and group supervision supported MI growth and development while also building a sense of community. Conclusion: Apart from challenges in learning and using MI, supervision was an important factor that helped peer health coaches develop. Future research should investigate training methods and supervision strategies to improve the quality of peer health coach programmes.
Groundwater Governance in India: A Legal and Institutional Perspective
Authors: Khara Deepratan Singh 
Published: November 2022

Availability of and accessibility to groundwater have played a considerable role in India’s development, especially in the agriculture sector. Although the groundwater boom has provided numerous advantages, it has also created a slew of intractable problems in terms of overexploitation and resource depletion, leading to the emergence of a groundwater crisis. Although there exists a policy structure to address these concerns, India’s legal framework for groundwater governance and management is complex and multi-layered, with constitutional and statutory provisions of both the Central and state governments. The present article aims to explore the nuances of groundwater governance in India from legal and institutional perspectives in an integrated manner. It examines the constitutional and right-based aspects of groundwater management as well as the evolution of associated groundwater policy measures undertaken so far.

Published: November 2022

Objectives To determine the effects on sedentary behaviour of an approach that promotes reduction in sedentary behaviour in patients with minor ischaemic stroke after intervention and at follow-up. Design A randomised controlled trial. Setting During hospitalisation and after hospital discharge Subjects In total, 86 patients with minor ischaemic stroke admitted to an acute care hospital were assigned to the intervention (n = 43) and control (n = 43) groups. Intervention An intervention group that received an approach to reduce sedentary behaviour upon hospital admission until 3 months after discharge (education, self-monitoring, phone calls, etc.) and a control group that received the usual care during hospitalisation. From 3 to 6 months after discharge, no group received any intervention. Main Outcome The primary outcome was the change (%) in sedentary behaviour from baseline to post-intervention (3 months after discharge) and follow-up (6 months after discharge). Sedentary behaviour was measured at baseline (upon hospital admission), post-intervention, and at follow-up using accelerometers. Results At the post-intervention stage, the intervention group showed a significantly greater change in sedentary behaviour from baseline than that shown by the control group (sedentary behaviour: intervention group, −22.7%; control group, −14.9%; P = 0.013; effect size = 0.58). At follow-up too, the intervention group showed a significantly greater change in sedentary behaviour from baseline than that shown by the control group (sedentary behaviour: intervention group, −20.4%; control group, −13.6%; P = 0.025; effect size = 0.54). Conclusions An approach to reduce sedentary behaviour in patients with minor ischaemic stroke effectively reduces sedentary behaviour, which is sustained up to follow-up.
