Background: Despite the presence of evidence-based policies and guidelines, and in line with lingering issues in resource availability in low-income settings, inconsistencies are still being documented in the provision of adequate nutritional support and medication administration via the enteral route. Aims: The study aimed to, first, describe the practices of nurses in enteral nutrition and medication administration in the context of a low-resource setting and, second, explore the factors that are associated with the performance of such practices. Methods: The study used a descriptive correlational design. Quota sampling of nurses (n=138) working in wards and intensive care units of a tertiary hospital for adult patients requiring enteral nutritional support was performed. Enteral feeding and medication practices were assessed using a self-report survey. Ethical approval was obtained from an institutional review board. Findings: The majority of nurses correctly identified X-ray as the gold standard for determining tube placement (58.5%). However, only 13.5% correctly identified air insufflation as an unreliable method. Scores on knowledge and skills on enteral feeding and medication were found to have a significant, strong positive correlation (r=0.855, p<0.01). Conclusions: Strengthening of knowledge on standards of enteral nutrition and medication practices may improve the performance of the skill in actual bedside practice. Addressing documented gaps in practices and standards may have an impact on the provision of safe and quality nursing care.
How not to miss infective causes of hip pain in children
Authors: Oliver Emile , Sinha Pranab , Khwaja Murtaza , Thilagarajah Michael 
Published: May 2021

A referral from accident and emergency for a child with hip pain is a scenario commonly faced by orthopaedic juniors on call. The list of differentials is vast and can make assessment and diagnosis challenging, with severe consequences if diagnosis is delayed or missed. Three common causes of paediatric hip pain are septic arthritis, transient synovitis and osteomyelitis. These can all present as a child with atraumatic hip pain, irritability, fever and refusal to weight bear. Differentiating between them can be challenging. A thorough history and examination, combined with appropriate investigations and imaging, is essential. Early diagnosis and prompt treatment are key to reducing irreversible secondary sequelae of joint destruction and long-term functional impairment.
Effectiveness of e-learning to develop the ability to recognise and manage stroke
Authors: Mortimer Craig 
Published: May 2021

Background: With stroke continuing to affect people in the UK and around the world, the need to develop health professionals in the management of patients with the condition and ensuring staff can meet the requirements of guidelines is key. Aim: This study aimed to assess the effectiveness of e-learning to develop ambulance staff in the management of acute stroke and stroke mimics by looking at their engagement with the course and knowledge attainment. Method: A small-scale study focused on an e-learning course on stroke management and before and after questionnaires. Results: Participants demonstrated good engagement with the course. However, the before and after questionnaire results were mixed, with 46% of participants demonstrating an increase in their knowledge up to 6 weeks after undertaking the course, 32% remaining the same and 22% showing a decrease. Conclusion: The data suggest more around the general approach to e-learning rather than on the topic of stroke management. Regardless of the course's content and its overall effectiveness, if students do not afford a suitable amount of time to engage with the learning materials, their ability to develop is greatly diminished.

The lattice parameters, electronic bandgap, and imaginary and real parts of the dielectric function, along with the optical absorption coefficient, are calculated. Density functional perturbation theory is employed to compute the optical properties in the photon energy range from 0.0 to 30 eV. No structural or phase-type transformation is noticed under the applied pressure, which resulted in a uniform contraction of the unit cell. Bandgap variation is seen in all the structures, with the maximum (1.65 eV) and minimum (1.46 eV) decrease found for doped and undoped

Authors: Bondeelle Louise , Chevret Sylvie , Cassonnet Stéphane , Harel Stéphanie , Denis Blandine , de Castro Nathalie , Bergeron Anne ,   on behalf of The Saint Louis CORE Team Group
Published: May 2021

Objectives
Although some prognostic factors for COVID-19 were consistently identified across the studies, differences were found for other factors that could be due to the characteristics of the study populations and the variables incorporated into the statistical model. We aimed to a priori identify specific patient profiles and then assess their association with the outcomes in COVID-19 patients with respiratory symptoms admitted specifically to hospital wards.

Methods
We conducted a retrospective single-center study from February 2020 to April 2020. A non-supervised cluster analysis was first used to detect patient profiles based on characteristics at admission of 220 consecutive patients admitted to our institution. Then, we assessed the prognostic value using Cox regression analyses to predict survival.

Results
Three clusters were identified, with 47 patients in cluster 1, 87 in cluster 2, and 86 in cluster 3; the presentation of the patients differed among the clusters. Cluster 1 mostly included sexagenarian patients with active malignancies who were admitted early after the onset of COVID-19. Cluster 2 included the oldest patients, who were generally overweight and had hypertension and renal insufficiency, while cluster 3 included the youngest patients, who had gastrointestinal symptoms and delayed admission. Sixty-day survival rates were 74.3%, 50.6% and 96.5% in clusters 1, 2, and 3, respectively. This was confirmed by the multivariable Cox analyses that showed the prognostic value of these patterns.

Conclusion
The cluster approach seems appropriate and pragmatic for the early identification of patient profiles that could help physicians segregate patients according to their prognosis.
Seeing faces, when faces can‘t be seen: Wearing portrait photos has a positive effect on how patients perceive medical staff when face masks have to be worn

Published: May 2021

Introduction
Since the onset of the coronavirus disease 2019 (COVID-19) pandemic, wearing surgical face masks has become mandatory for healthcare staff in many countries when interacting with patients. Recently, it has been shown that wearing face masks impairs social interaction by diminishing a person’s ability to read the emotion of their counterparts, an essential prerequisite to respond adequately in social situations. It is easily conceivable that this may have a tangible negative influence on the communication and relationship between patients and healthcare personnel. We therefore investigated whether it has an effect on how patients perceive healthcare professionals when physicians and nursing staff wear portrait photos with their smiling faces in addition to face masks.

Methods
During the study period of 16 days, the medical staff of our Department wore surgical face masks at all times during any kind of interaction with patients. In a pseudorandomized order, all members of our staff additionally affixed their portrait photos to their work clothes on 8 of the 16 days. After completion of their visit, 226 patients were interviewed anonymously in a cross-sectional study design using a questionnaire in which they rated the following three items: friendliness of staff, medical quality of treatment, and how well they felt taken care of during treatment in our Department.

Results
On days, on which staff wore photos, mean scores of the questionnaires were significantly higher than on non-photo days (p = 0.013; mean ± standard deviation = 92.8 ± 11.3 vs. 91.0 ± 12.6; median (range) = 97 (98) vs. 96 (76)). When analyzed separately, the increased scores were only significant for the item friendliness of staff (p = 0.009; mean ± standard deviation = 95.8 ± 6.3 vs. 92.2 ± 11.5; median (range) = 98 (39) vs. 97 (54)).

Conclusion
Our study suggests that the use of portrait photos with smiling faces has a positive effect on how patients perceive healthcare staff.
How recreational marathon runners hit the wall: A large-scale data analysis of late-race pacing collapse in the marathon
Authors: Smyth Barry 
Published: May 2021

Introduction
In the marathon, how runners pace and fuel their race can have a major impact on race outcome. The phenomenon known as hitting the wall (HTW) refers to the iconic hazard of the marathon distance, in which runners experience a significant slowing of pace late in the race, typically after the 20-mile mark, and usually because of a depletion of the body’s energy stores.

Aim
This work investigates the occurrence of significant late-race slowing among recreational marathoners, as a proxy for runners hitting the wall, to better understand the likelihood and nature of such slowdowns, and their effect on race performance.

Methods
Using pacing data from more than 4 million race records, we develop a pacing-based definition of hitting the wall, by identifying runners who experience a sustained period of slowing during the latter stages of the marathon. We calculate the cost of these slowdowns relative to estimates of the recent personal-best times of runners and compare slowdowns according to runner sex, age, and ability.

Results
We find male runners more likely to slow significantly (hit the wall) than female runners; 28% of male runners hit the wall compared with 17% of female runners, χ2(1, N = 1, 928, 813) = 27, 693.35, p < 0.01, OR = 1.43. Such slowdowns are more frequent in the 3 years immediately before and after a recent personal-best (PB) time; for example, 36% of all runners hit the wall in the 3 years before a recent PB compared with just 23% in earlier years, χ2(1, N = 509, 444) = 8, 120.74, p < 0.01, OR = 1.31. When runners hit the wall, males slow more than females: a relative slowdown of 0.40 vs. 0.37 is noted, for male and female runners, when comparing their pace when they hit the wall to their earlier race (5km-20km) pace, with t(475, 199) = 60.19, p < 0.01, d = 0.15. And male runners slow over longer distances than female runners: 10.7km vs. 9.6km, respectively, t(475, 199) = 68.44, p < 0.01, d = 0.17. Although, notably the effect size of these differences is small. We also find the finish-time costs of hitting the wall (lost minutes) to increase with ability; r2(7) = 0.91, p < 0.01 r2(7) = 0.81, p < 0.01 for male and female runners, respectively.

Conclusions
While the findings from this study are consistent with qualitative results from earlier single-race or smaller-scale studies, the new insights into the risk and nature of slowdowns, based on the runner sex, age, and ability, have the potential to help runners and coaches to better understand and calibrate the risk/reward trade-offs that exist as they plan for future races.
An Uncommon Cause of Biliary Obstruction in a Patient With Budd-Chiari Syndrome
Authors: Mago Sheena , Mavilia Marianna , Swales Colin Thomas 
Published: May 2021

ABSTRACT
Biliary varices (BVs) are an infrequent complication of chronic portal hypertension. Most cases of BVs are asymptomatic and are likely underdiagnosed. We present a case of a 34-year-old woman with Budd-Chiari syndrome who was found to have BVs caused by a significant inferior vena cava (IVC) stenosis. This case demonstrates that preprocedure imaging for variceal screening should be considered before biliary tract procedures to prevent complications.
More Future? Straight Ecologies in British Climate-Change Theatre
Authors: de Waal Ariane 
Published: May 2021

AbstractAttempts to convey the urgency of the climate crisis often rely on the figure of the child. From Greta Thunberg via school-striking students to the grandchildren invoked in the titles of bestselling books about global warming, appearances of children seem especially effective in protesting the loss of a habitable planet. The iconic child that needs saving (or becomes the planet’s saviour) is equally prominent in British plays about climate change. Drawing on queer critiques of the conceptual short circuit between the child and the future, this article identifies two waves of UK eco-theatre: the first wave endorses hetero-nuclear family bonds and future-oriented thinking; the second wave traces alternative relations to nonhuman, ageing, or ailing Others in the present. The first part of the article revisits critiques of reproductive futurism; the second examines the straight ecologies that characterise the first wave of eco-theatre, based on a detailed analysis of Duncan Macmillan’s playLungs(Studio Theatre, Washington, DC/Sheffield Crucible, 2011). The final part considers climate-change plays that sever reproductive timelines, as exemplified by Caryl Churchill’sEscaped Alone, Lucy Kirkwood’sThe Children, and Stef Smith’sHuman Animals(all Royal Court, 2016).
String Figures of Response-ability and the Refusal to Respond in Clare Pollard’sThe Weather
Authors: Wächter Cornelia 
Published: May 2021

AbstractThis article discusses Clare Pollard’sThe Weather(Royal Court, 2004) with a focus on how the play critiques the widespread failure to assume responsibility for both personal and collective wrongdoing as symptomatic of the Anthropocene and Capitalocene. More specifically, the paper reads Pollard’s play through the prism of Donna Haraway’s conception of science fiction as a figure, denoting “science fiction, speculative fabulation, string figures, speculative feminism, science fact, so far” (2) in order to demonstrate that it does contain a utopian kernel in its uncovering of the (affective) strings that bind individuals to the logic of the society of consumers (Bauman) and in its final appeal to cut those strings, even though the play does not actually transcend the capitalist imaginary.
Travel Beyond Stars: Trauma and Future in Mojisola Adebayo’s STARS
Authors: Baas Renzo 
Published: May 2021

Abstract
The article explores Mojisola Adebayo’s two-hander STARS (preliminary workshop performance, Ovalhouse, 2018) through the lens of Afrofuturism. The play will be discussed in regard to future-making technologies. By analysing the overt as well as subtle references to science fiction and its tropes, this article lays out how Afrofuturism informs the play and how it is formative in liberating the main character. Furthermore, questions of violence against women, forms of resistance, and the function of the imagination will be examined. Adebayo deftly weaves Afrofuturist concerns into the everyday experiences of marginalised groups who face discrimination and exclusion, irrespective of whether their marginalisation is based on culture, gender, or age. Through this, the play offers ways of dealing with bodily and historical trauma and exclusion, while simultaneously addressing violent and harmful practices and power relations. The play may be set in the present and deals with current issues, but its performance of the future – in regard to resistance and liberation – proves to be its central feature.
Dehn functions of finitely presented metabelian groups
Authors: Wang Wenhao 
Published: May 2021

AbstractIn this paper, we compute an upper bound for the Dehn function of a finitely presented metabelian group. In addition, we prove that the same upper bound works for the relative Dehn function of a finitely generated metabelian group. We also show that every wreath product of a free abelian group of finite rank with a finitely generated abelian group can be embedded into a metabelian group with exponential Dehn function.
Planned Obsolescence with Network Effects
Authors: Gutiérrez Oscar 
Published: May 2021

Abstract
This paper appeals to the interplay between network effects and quality to justify the use of planned obsolescence by well-settled firms. We propose a simple contagion model to analyze an asymmetric duopoly market where an incumbent firm benefits, at least initially, from the first‐mover advantages attributed to network industries, while the entrant offers a product with higher quality. The simpler version of the model describes the evolution of the market shares, showing that network effects can overtake the quality effect if the market is sufficiently small. If the market lasts enough, network effects end up enhancing the effect of quality and the entrant gets a higher market share. If the incumbent can set the size of the market by launching a new product every so often, the model provides a rationale for the use of planned obsolescence from a strategic point of view. Social efficiency is then challenged.
Symbolische Verfassungsgebung in Aushandlungsprozessen von Religion. Die Verfassungsdynamik einer Handschlagverweigerung
Authors: Kühler Anne 
Published: May 2021

Zusammenfassung
Der sogenannte Fall Therwil führte zu Bestrebungen, in der Verfassung des Kantons Basel-Landschaft einen Vorbehalt bürgerlicher Pflichten zu verankern. Diese geplante und schlussendlich gescheiterte Verfassungsrevision ist Anlass, der Frage nach der Bedeutung des Vorbehalts der bürgerlichen Pflichten nachzugehen. Es zeigt sich, dass dessen Bedeutung nicht in seiner rechtlich verbindlichen und durchsetzbaren, sondern in seiner symbolischen Dimension liegt. Diese wird im Fall Therwil eingesetzt, um einer bestimmten politischen Zielsetzung zu dienen. Dies zeigt sich deutlich mit Blick auf den migrationspolitischen Hintergrund der sog. Handschlag-Affäre, werden mit der geplanten Verfassungsrevision doch implizite wie explizite Imaginationen von Zugehörigkeit ausgedrückt. Es ist dabei kein Zufall, dass mit dem Vorbehalt bürgerlicher Pflichten ein Konzept aufgegriffen wurde, das dem Kontext des Kulturkampfes im 19. Jahrhundert entstammt.
Ein lokales Ereignis im globalen Fokus: Das Zusammenfallen geografischer, zeitlicher und sozialer Räume in der medialen Verbreitung einer Handschlagverweigerung
Authors: Stahel Lea 
Published: May 2021

Zusammenfassung
Lokale, religionsbezogene Ereignisse werden vermehrt global diskutiert – auch die „Handschlag-Affäre“. Bauend auf Forschung zu Öffentlichkeit, zusammenfallenden Kontexten und islamfeindlichen Online-Diskursen argumentiert der Beitrag, dass in der medialen Verbreitung der Affäre geografische, zeitliche und soziale Räume zusammenfielen, was die negativen Folgen für die involvierten Akteure miterklärt. Das geografische und zeitliche Zusammenfallen wird anhand von Metadaten von 279 Nachrichten- und 152 Webseiten-/Blog-Artikeln (dt. und engl.; veröffentlicht 2015–2017) veranschaulicht. Das soziale Zusammenfallen wird durch eine thematische Analyse von 45 Webseiten-/Blog-Artikeln der islamfeindlichen Online-Öffentlichkeit illustriert. Ergebnisse zeigen eine mediale Ausbreitung von lokal zu global (geografische Räume), eine Zeitverzögerung zwischen Ereignis und Skandalisierung (zeitliche Räume) und eine ideologische Rekontextualisierung in der islamfeindlichen Öffentlichkeit (soziale Räume).

Abstract
Diese Veröffentlichung ist der zweite Teil zu KI-Studien für KMU. Im ersten Teil wurden Herausforderungen beschrieben. In diesem zweiten Beitrag wird ein Bewertungsinstrument vorgestellt. Im Bereich des Technologiemanagements ist die Bewertung neuer digitaler Technologien ein anspruchsvoller Prozess. Die meisten Bewertungen konzentrieren sich auf Kosten und Nutzen. Diese Ansätze scheitern oft, weil wesentliche Punkte vernachlässigt werden. In diesem Beitrag wird der ganzheitliche Ansatz der „Five Dimension of Digital Technology Assessment Cycle“ am Beispiel von KI beschrieben. Der „5-Dimensionen Assessment Cycle“ beginnt mit dem Nutzen, bewertet die Technologiebereitschaft und die Usability, fährt fort mit der Unternehmensbereitschaft und endet mit der Bewertung der Kosten.

Konzept einer automatisierten und modularen Befundungsstation in der wandlungsfähigen Produktion
Authors: Kaiser Jan-Philipp , Mitschke Norbert , Stricker Nicole , Heizmann Michael , Lanza Gisela 
Published: May 2021

Abstract
Inspektionsprozesse werden im Remanufacturing auch heute noch vorwiegend manuell durchgeführt, da die Einschätzung des Qualitätszustands von rückläufigen Gebrauchtprodukten komplex und damit schwer zu automatisieren ist. Dies ist darauf zurückzuführen, dass Abnutzungsgrade, Deformationen und Schädigungen eine individuelle Bewertung des Gebrauchtprodukts nach sich ziehen und somit schwer standardisierbar sind. In diesem Beitrag werden die Anforderungen an ein System für die Bewältigung der Herausforderung der automatisierten Inspektion im Remanufacturing abgeleitet. Darauf aufbauend wird das Konzept einer Befundungsstation, welches diese Anforderungen erfüllt, präsentiert und Anwendungsfälle im Rahmen des von der Carl-Zeiss-Stiftung geförderten Forschungsprojekts „AgiProbot - Agiles Produktionssystem mittels mobiler, lernender Roboter mit Multisensorik bei ungewissen Produktspezifikationen“ vorgestellt.
