Authors: Killington Maggie , Pearson Ginny , Campbell Emma , Snigg Michael 
Published: February 2021

Background/AimsFatigue after brain injury is common and enduring, and rehabilitation improves patient understanding and strategy development. The aim of this study was to determine whether therapy supporting fatigue management can be provided economically in groups to inpatients undertaking rehabilitation.MethodsA mixed-methods study was undertaken, including a pilot randomised control trial and a parallel qualitative investigation. A total of 78 adult inpatients with moderate to severe acquired brain injury were recruited to the study; 40 were allocated to routine usual care and 38 were allocated to the intervention, which consisted of routine usual care plus four group therapy sessions that took place over 2 weeks, run by an experienced occupational therapist. Participants were aged between 18 and 65 years and were considered to be able to manage learning in a group setting. Outcome measures were collected at baseline and at the end of the therapy intervention (Barrow Neurological Institute Fatigue Scale, Quality of Life after Brain Injury questionnaire and a Fatigue Knowledge questionnaire assessing knowledge related to the aims of the education modules). A qualitative study was conducted after the quantitative investigation in the form of patient interviews. A total of 10 patients were interviewed to discuss their fatigue journey and impressions of receiving fatigue management therapy in a group.ResultsA repeated measures analysis of variance with time as a within-subject factor and group as a between-subjects factor showed no interaction effect of group × time for fatigue, quality of life or acquisition of knowledge; however, knowledge improved over time, irrespective of group allocation (P<0.01). Although most participants found the group work satisfactory in terms of overall knowledge development, a number would have preferred to address their specific fatigue issues in an individual session. Participants described a confusing journey understanding fatigue symptoms before therapy, but reported an improved understanding and acquiring management strategies after receiving the educational therapy sessions.ConclusionsEducation regarding fatigue following brain injury can be provided successfully to inpatients receiving rehabilitation in group settings. However, it may be important to build in an additional individual therapy session to address each patient's individual issues and queries.

Aims Restarting planned surgery during the COVID-19 pandemic is a clinical and societal priority, but it is unknown whether it can be done safely and include high-risk or complex cases. We developed a Surgical Prioritization and Allocation Guide (SPAG). Here, we validate its effectiveness and safety in COVID-free sites. Methods A multidisciplinary surgical prioritization committee developed the SPAG, incorporating procedural urgency, shared decision-making, patient safety, and biopsychosocial factors; and applied it to 1,142 adult patients awaiting orthopaedic surgery. Patients were stratified into four priority groups and underwent surgery at three COVID-free sites, including one with access to a high dependency unit (HDU) or intensive care unit (ICU) and specialist resources. Safety was assessed by the number of patients requiring inpatient postoperative HDU/ICU admission, contracting COVID-19 within 14 days postoperatively, and mortality within 30 days postoperatively. Results A total of 1,142 patients were included, 47 declined surgery, and 110 were deemed high-risk or requiring specialist resources. In the ten-week study period, 28 high-risk patients underwent surgery, during which 68% (13/19) of Priority 2 (P2, surgery within one month) patients underwent surgery, and 15% (3/20) of P3 (< three months) and 16% (11/71) of P4 (> three months) groups. Of the 1,032 low-risk patients, 322 patients underwent surgery. Overall, 21 P3 and P4 patients were expedited to ‘Urgent’ based on biopsychosocial factors identified by the SPAG. During the study period, 91% (19/21) of the Urgent group, 52% (49/95) of P2, 36% (70/196) of P3, and 26% (184/720) of P4 underwent surgery. No patients died or were admitted to HDU/ICU, or contracted COVID-19. Conclusion Our widely generalizable model enabled the restart of planned surgery during the COVID-19 pandemic, without compromising patient safety or excluding high-risk or complex cases. Patients classified as Urgent or P2 were most likely to undergo surgery, including those deemed high-risk. This model, which includes assessment of biopsychosocial factors alongside disease severity, can assist in equitably prioritizing the substantial list of patients now awaiting planned orthopaedic surgery worldwide.

Published: February 2021

In this work, we report the performance study of InGaN-based green light-emitting diodes (LEDs) with on-chip photodetectors (PDs) based on wire-bonding and flip-chip configurations. Compared with a conventional wire-bonding design, the LED-PD device, which incorporates a flip-chip design, can offer superior optical and thermal performances and, under an LED current of 200 mA, its light output and detected photocurrent increase by 37.7% and 14.7%, respectively. The different extents of enhancement in both light output and photocurrent are also studied by analyzing their optical, electrical, and thermal properties under varying LED currents. The results provide important guidance for the design of LED-PD integrated systems operating at different current densities.
Biomechanical evaluation of high tibial osteotomy plate with internal support block using finite element analysis
Authors: Yang Jesse Chieh-Szu , Lin Kuan-Yu , Lin Hsi-Hsien , Lee Oscar K. 
Published: February 2021

Background/Objective
High tibial osteotomy (HTO) is a common treatment for medial knee arthrosis. However, a high rate of complications associated with a plate and a significant loss of correction have been reported. Therefore, an internal support block (ISB) is designed to enhance the initial stability of the fixation device that is important for successful bone healing and maintenance of the correction angle of the osteotomy site. The purpose of this study was performed to examine if an internal support block combined with a plate reduces the stress on the plate and screw area.

Methods
Finite element models were reconstructed following three different implant combinations. Two loading conditions were applied to simulate standing and initial sit-to-stand postures. Data analysis was conducted to evaluate the axial displacement of the posteromedial tibial plateau, which represents the loss of the posteromedial tibial plateau in clinical observation. Moreover, the stresses on the bone plate and locking screws were evaluated.

Results
Compared to the TomoFix plate, the ISB reduced the axial displacement by 73% and 76% in standing and initial sit-to-stand loading conditions, respectively. The plate with an ISB reduced stress by 90% on the bone plate and by 73% on the locking screw during standing compared to the standalone TomoFix plate. During the initial sit-to-stand loading condition, the ISB reduced the stress by 93% and 77% on the bone plate and the locking screw, respectively.

Conclusion
The addition of the PEEK block showed a benefit for structural stability in the osteotomy site. However, further clinical trials are necessary to evaluate the clinical benefit of reduced implant stress and the internal support block on the healing of the medial bone tissue.
Canadian resource guides for individuals and families affected by primary immunodeficiency
Authors: Shama Wendy 
Published: February 2021

A diagnosis of immunodeficiency can be challenging for families as they navigate the emotional impact of this diagnosis, as well as the potential financial burden of treatment. For rare diseases such as primary immunodeficiency (PI), patients are often required to take a proactive role in managing their own care and may be engaged with health care providers who have minimal experience with PI disease. These providers may also have limited access to information on the resources available for this population. A review of the information available showed that a paucity of information existed for these families who were looking for appropriate resources related to their diagnosis. The PI Social Work Network was established in 2011 by Immunodeficiency Canada to develop a network of social workers across Canada who work with patients diagnosed with PI. This network has had a focus on support programs, education, and research. Resource guides were created by the network to support families by providing information on both provincial as well as national resources available. While these lists are not exhaustive, there is an attempt to keep them as up to date as possible. If additional psychosocial support would be beneficial or a family requires support accessing resources, they should be directed to their local hospital social worker, or they may contact Wendy Shama, MSW, RSW, at Immunodeficiency Canada. Statement of novelty: National and provincial resources guides have been created for families and individuals affected by primary immunodeficiency.

Zusätzlich wird eine Methode zur Schätzung des zukünftigen Fahrerverhaltens auf Basis der optimalen Regelung vorgestellt, mit der die zukünftigen Referenzwerte für die modellprädiktive Regelung geschätzt werden, um so den prädiktiven Charakter des Verfahrens auch in der Online-Anwendung voll ausnutzen zu können.
Christliche Identitäten und die Synchronisierung der Zeit in der Antike
Authors: Markschies Christoph 
Published: February 2021

Zusammenfassung
In dem Beitrag wird das Problem, wie unterschiedliche Zeitangaben, Zeitvorstellungen und Zeitmessungen synchronisiert werden können, an Beispielen aus der Antike behandelt. Dazu wird der Begriff »Synchronisation« und seine Bedeutungen untersucht, dann antike wissenschaftliche Literatur zur Bearbeitung von Synchronisationsproblemen (insbesondere die Chronik des Eusebius) in den Blick genommen, weiter die Bedeutung von Synchronisation im Alltag für die Identität von Gruppen und Untergruppen (anhand eines Festkalenders einer römischen Garnison im Osten des Imperium) studiert und schließlich einige Konsequenzen aus diesen Beobachtungen für das Verständnis antiker Gesellschaften formuliert.
Das sozialistische »Königreich Gottes auf Erden« als Erfüllung der Heilsgeschichte
Authors: Strube Julian 
Published: February 2021

Zusammenfassung
Die frühen sozialistischen Strömungen in Frankreich, und insbesondere ihre religiösen Ansichten, wurden von der marxistischen Historiographie als »utopisch« marginalisiert. Dieser Beitrag konzentriert sich auf die heilsgeschichtlichen Theorien der Saint-Simonisten, die eine Einheit von Religion und Politik anstrebten. Im Lichte der Polemiken zwischen ihnen und der neo-katholischen Bewegung um Félicité de Lamennais wird die Verflechtung von Sozialismus und Katholizismus von den 1820er bis in die 1840er Jahre herausgestellt. Es wird argumentiert, dass ein eschatologisches Geschichtsbild für die Frühsozialisten essentiell war und auch auf spätere Sozialisten nachhaltigen Einfluss ausübte.
Außerwestliche Konzepte von Zeit am Beispiel China
Authors: Meyer Christian 
Published: February 2021

Zusammenfassung
Der Beitrag zeigt anhand von Schlaglichtern aus dem vormodernen China, dass es in außerwestlichen Kontexten im Vergleich zu den europäisch-vorderasiatischen respektive abrahamitischen Traditionen zwar durchaus Konvergenzen, aber auch gravierende Unterschiede im Zeitverständnis gibt. Dabei finden sich zyklisch-kalendarische, historisch-unilineare und situationelle Zeitkonzepte nebeneinander in jeweils unterschiedlichen Funktionskontexten.
Incidental L2 Vocabulary Acquisition and Reading: Concerns, Progresses and Future Directions
Authors: Wang Qian 
Published: February 2021

Abstract
There has been a consensus that vocabulary knowledge has become a major contributor to L2 learners ’ efficient communication and comprehension. Incidental vocabulary acquisition relates to lexical gains as a by-product resulting from accomplishing another activity which is not aimed at learning vocabulary. This article intends to provide a digest of research on incidental vocabulary acquisition over the past few decades by primarily focusing on related theoretical frameworks, possible explanatory variables mediating incidental vocabulary learning, and tasks targeted at enhancing incidental lexical growth. In line with analyses of findings yielded from an impressive number of illuminating studies conducted, this article calls for a diversification of efforts in relation to multi-word lexical items, multi-modal e-learning technologies, and insights from neuroscience that may warrant more scholarly attention. These possible areas would further enrich the current scope of L2 incidental vocabulary acquisition research.
Lectura Dantis: Paradiso VII
Authors: Kilian Sven Thorsten 
Published: February 2021

Riassunto
Nel sottolineare gli aspetti narrativi del canto, la lectura intende concentrarsi sul problema della rappresentabilità della fede. Conforme alla dottrina dei quattro elementi, il ragionamento di Dante distingue tra la facoltà di percezione limitata della natura lapsa, che descrive in termini di cecità, e l’autorizzazione a trascendere, grazie alla perfezione di Beatrice, mediatrice del logos divino, quella natura data al protagonista e ai lettori del poema. Questa messinscena della trascendenza corrisponde alla necessità storica di una delimitazione teologica della setta ebraica.
Ethnolinguistic Identity, Coping Strategies and Language Use among Young Hungarians in Slovakia
Authors: Vincze Laszlo , Dragojevic Marko , Gasiorek Jessica , Miočević Milica 
Published: February 2021

Abstract
The purpose of the present paper was to investigate the propositions of ethnolinguistic identity theory among young Hungarian speakers in Slovakia. Specifically, we aimed to explore the role of ethnolinguistic identification, vitality and boundary permeability in coping with negative ethnolinguistic identities, and also how these effects impact language use. Self-report questionnaire data were collected among Hungarian-speaking secondary school students in (N = 311). The data were analyzed using a Bayesian moderated mediation analysis with informative priors for coefficients based on an earlier study. The results provided mixed support for the hypotheses. Ethnolinguistic mobility appeared to be an outcome of a complex process, where identification, vitality and permeability operate interactively; at the same time, ethnolinguistic competition was independent of the perception of vitality and permeability, but a sole consequence of strong Hungarian identification. In addition, the results indicated that identification, vitality and competency in the outgroup language were factors predicting language use, whereas there was no support for the anticipated mediating effect of coping strategies. Findings are discussed in relation to ethnolinguistic identity theory and to the particular qualities of the local context.
From foreign language teaching methodology to comparative glottodidactics
Authors: Gębal Przemysław Ernest , Nawracka Monika Janina 
Published: February 2021

AbstractThe article presents the results of a diachronic analysis of language education in Poland from the 1950 s to the present day. We reflect on the evolution of theoretical thinking on language teaching methodology and its influence on everyday teaching practice. The approach taken is chronological, both in terms of the description of theory which is developed and implemented as well as the language education. This is an arbitrary choice which we feel is justified by the socio-political context. The analysis starts with a presentation of the tradition of teaching foreign languages in Poland followed by a description of use of terminology. Qualitative empirical research from structured interviews with researchers who have significantly influenced contemporary Polish glottodidactics is used to complement the analysis.
Localising Chinese language curriculum construction: A case study in an Australian primary school
Authors: Zhao K. 
Published: February 2021

AbstractChinese is now the second most commonly spoken language in Australia. There is a growing interest in learning Chinese in local schools. However, it is reported that the principally English-speaking learners in Australia have great difficulties and challenges in learning Chinese. The high dropout rate in Chinese courses demonstrates this. This paper presents a case study conducted in a local public school in New South Wales. The purpose of this study is to explore and employ the local students’ daily recurring sociolinguistic activities, performed in English at school, for creating suitable learning content. In this way, a localised Chinese curriculum is constructed in the Australian educational environment. The case study shows that the local students’ translanguaging aptitudes between English and Chinese are developing and becoming influential, as they have engaged in learning Chinese in the form of a local practice – playing chess, which is a typical instance of their daily recurring sociolinguistic activities in school. Therefore, in the process of such contextualised learning practices, not only can Chinese be made learnable for them, but also the specific vocabulary learnt can be the basis for their wider learning of Chinese in the future.
Microstructure and Tribological Properties of TPU/Fluoropolymer Composites
Authors: Rohm K. , Amirkhosravi M. , Manas-Zloczower I. 
Published: February 2021

Abstract
A network of poly(tetrafluoroethylene) (PTFE) microfibers in a thermoplastic polyurethane (TPU) was prepared by melt mixing the TPU with solid PTFE particles. The effect of rotor speed on the fiber dimensions was investigated. Higher shear stress was found to be the critical parameter for producing thinner PTFE fibers, rather than the shear rate imposed by the mixer. Shear stress transfer from the melt to the PTFE crystal results in solid phase plastic deformation, and the efficiency of the deformation depends on the shear stress in the matrix. All of the PTFE fiber/TPU composites show lower coefficients of friction compared with the neat TPU. The magnitude of the coefficient of friction was found to correlate with the interfacial area between PTFE and TPU generated by the microfiber network. However, for macroscale PTFE agglomerates, the reduction in the coefficient of friction is mostly affected by the uneven distribution of PTFE in the bulk and on the molded part surface.

Authors: Cassagnau P. 
Published: February 2021

Abstract
This paper presents so-called inverse rheology methods to determine various parameters that are essential to go further in terms of modelling and/or simulation in the field of polymer processing. The following systems from our previous works are presented: i) Determination of the molecular structure of a poly(e-caprolactone) polymerized in-situ by ring-opening; ii) Measurement of the mutual diffusion coefficient: two cases are considered, namely the diffusion of a plasticizer and the diffusion of an organic peroxide in a polymer melt and iii) Determination of the average length of polymer nanofibers in suspension and study of the universal behavior of nanofibers of different natures in dilute and semi-dilute suspensions. The application of these different studies in the field of reactive extrusion, blending and multi-scale structuring are presented and discussed.
Preparation, Characterization and Processing of PCL/PHO Blends by 3D Bioplotting
Authors: Gopi S. , Ramsay B. A. , Ramsay J. A. , Kontopoulou M. 
Published: February 2021

Abstract
Blends of polycaprolactone (PCL) and poly(3-hydroxyoctanoate) P(3HO) were prepared by melt compounding. These immiscible blends exhibited droplet-matrix morphology at compositions up to 30 wt% P(3HO). Even though the addition of amorphous P(3HO) decreased the crystallinity of PCL, the crystallization temperature of the blends increased by 6 to 7 8C. Blends containing up to 30 wt% P(3HO) had higher crystallization rates, and lower crystallization half-times compared to neat PCL. The viscosity of PCL decreased upon addition of P(3HO), making the blends suitable for processing using a 3D bioplotter. Compositions with 10 to 30 wt% P(3HO) were ideal for processing, because of their improved crystallization kinetics, reduced stickiness and good flow properties. Estimation of the interfacial tension by fitting the Palierne model to the linear viscoelastic properties of the blends revealed good compatibility, which gave rise to synergistic effects in the thermal and mechanical properties. The fibres prepared by 3D bioplotting maintained droplet matrix morphology, with finer particle size than the original compounded material. In addition to favourable viscosity and thermal properties, the extruded fibres containing 30 wt% P(3HO) had comparable modulus to the neat PCL, while exhibiting good ductility. These blends may be suitable alternatives to PCL for biomedical applications, because they provide a range of crystallinities, crystallization rates and viscosities.
A Christian Art? Søren Kierkegaard’s Views on Music and Musical Performance Reconsidered
Authors: Petersen Nils Holger 
Published: February 2021

Abstract
While the only extensive discussion of music in Kierkegaard’s work is the famous treatise based on Mozart’s opera Don Giovanni in the first part of the pseudonymous Either/Or (1843), Kierkegaard did write other brief passages, in which he made comments on musical aspects. Two recent articles have pointed to attitudes toward music in such passages which seem to differ from the negative evaluation of music as a religious or theological medium in the first part of Either/Or by the fictitious aesthete A. With a point of departure in the two mentioned articles, I attempt to further discuss the possible relationship between the ethical and the aesthetic in Kierkegaard’s musical thought, involving passages from both parts of Either/Or as well as a few journal-entries. Finally, Erika Fischer-Lichte’s distinction between staging and performativity is brought to bear on these issues.
