Authors: Falkenberg Helene , Hansen Rasmus Præstmann 
Published: February 2022

ResuméArtiklen sætter fokus på gadeidrættens fritids- og ungdomspædagogiske potentialer og bidrager med viden om nye former for fritidsorganiseringer omkring gadekulturelle praksisser, f.eks. skateboarding, parkour og panna. Vi zoomer ind på, hvilke forhåbninger gadeidrættens aktører har til gadepædagogiske praksisser, og hvordan disse forhåbninger rummer en rettethed mod at skabe fællesskaber blandt udsatte unge. Gennem et interviewbaseret empirisk studie fremanalyserer vi to forskellige, men forbundne forhåbninger om dels gadeidrættens pædagogiske bidrag i forhold til udsatte ungdomsliv og dels orkestreringen af ungefællesskaber via gadeidrætsaktiviteter. Analyserne afslører det høje ambitionsniveau, der cirkulerer omkring gadeidrættens fritidsorganiseringer om at bidrage til sociale forandringer og fællesskaber gennem gadepædagogiske praksisser i storbyen.

The analysis shows how these hopes frame the desires of different street sport project organisers to orchestrate communities among socially vulnerable youth. In conclusion, the paper reveals the high ambitions that circulate around these street sport project to create social change and communities for socially vulnerable youth through urban street pedagogical practices.
Pædagogstuderende kan nå til forståelse af det almene gennem personlige fortællinger med afsæt i privatfotos
Authors: Nielsen Andreas 
Published: February 2022

ResumeI denne artikel undersøger jeg, hvordan studerende på pædagoguddannelsen kan udvikle et kropsligt stemt og etisk retningsgivende sprog ved at fortælle om egne livserfaringer med afsæt i privatfotos. I analysen viser jeg, hvordan abstrakte ord som fx fællesskab, livskvalitet, frihed og dannelse bliver stemt af de studerendes egne livserfaringer, når de i undervisningen med afsæt i privatfotos fortæller om væsentlige hændelser i deres eget liv. Den kropsfænomenologiske analyse viser, at stemtheden kommer til udtryk i deres kropssprog, fx i stemme og ansigtsmimik, og forplanter sig til tilhørerne gennem interkropslig resonans. Dermed synes der i undervisningsrummet at opstå en form for samstemthed, som giver den faglige samtale mening og substans. På baggrund af analysen argumenterer jeg for, at pædagogstuderende i højere grad, end det nu er tilfældet, bør have mulighed for at øve sig i at være til stede i ordene og i samtalen som personer; som subjekter, dvs. med deres egen krop og historie. Det gør det også muligt at erfare, at forståelse hermeneutisk betragtet er noget, vi kommer til forskellige steder fra, fx har vi hver især mødt og oplevet fænomenet fællesskab på forskellige måder. Det er ikke bare en vigtig erkendelsesmæssig pointe, men også en etisk og dannelsesmæssig: At undersøge og tage stilling til, hvad de værdier, som ordene er behæftet med, egentlig betyder, er også forbundet med at undersøge og lytte til, hvad de betyder for andre.
AbstractPedagogy students can reach an understanding of the general through personal stories based on private photos – Resonance, education and ethicsIn this article, I investigate how pedagogy students can develop a bodily founded and ethically guiding language by telling about their own life experiences based on private photos. I analyse how abstract words such as community, quality of life and freedom are affectively attuned by the students’ own life experiences. The phenomenological analysis shows that this affective attunement is expressed in their body language, for example in their voice and facial expressions, and spreads to the audience through inter bodily resonance. Thus, a form of shared affective attunement seems to arise in the classroom, which gives the academic conversation meaning and substance. Also, the students seem to get the opportunity to practice being present in words and in conversation as persons; as subjects, i.e. with their own body and history.
Journal Club Review of “Comparison of Two Rituximab Induction Regimens for Antineutrophil Cytoplasm Antibody–Associated Vasculitis: Systematic Review and Meta‐Analysis”
Authors: Elfishawi Mohanad 
Published: February 2022

ObjectiveThe objective of this study was to compare the efficacy and safety of two rituximab (RTX) regimens for the induction of remission in severe antineutrophil cytoplasm antibody‐associated vasculitis (AAV): the four‐dose (375 mg/m2 intravenously weekly) versus the two‐dose (1000 mg intravenously biweekly) regimen.MethodsA systematic review was performed to identify studies using the four‐ and/or two‐dose RTX regimens for induction of remission in severe AAV. Disease status 6 months after RTX infusion was required for inclusion. Patients were excluded if they received concomitant cyclophosphamide or plasma exchange. The primary end point was the proportion of patients in complete remission at 6 months. The pooled estimate was obtained by using meta‐analysis methods for proportions with random effects. Secondary end points included antineutrophil cytoplasm antibody status, number of patients with B‐cell depletion, mean prednisone dose, infections, and death.ResultsA total of 27 studies and 506 patients were included for analysis: 361 patients received the four‐dose regimen, and 145 patients received the two‐dose regimen. Most patients had relapsing disease at inclusion (83% and 92% of patients, respectively). There was no significant difference between the four‐ and two‐dose regimens, with a complete remission achieved in 85% (95% confidence interval [CI]: 70‐96) and 91% (95% CI: 79‐99) of patients, respectively. At 6 months, both regimens were associated with a similar mean daily prednisone dose (8.1 mg), infections (12% in both), and death (1% vs. 0%, respectively).ConclusionNo difference was found in terms of efficacy or safety between the four‐ and two‐dose RTX regimens for induction of remission in severe AAV.https://onlinelibrary.wiley.com/doi/10.1002/acr2.11274Bénard V, Farhat C, Zarandi‐Nowroozi M, Durand M, Charles P, Puéchal X, et al.

AbstractThe power conversion efficiencies (PCEs) of organic solar cells (OSCs) have surpassed 19% thanks to the innovation of polymer donors and molecular acceptors. However, the batch‐to‐batch variations in polymer materials are detrimental to the reproducibility of the device performance. In comparison, small‐molecule donors (SMDs) possess some unique advantages, such as well‐defined molecular weights, easy purification, and excellent batch‐to‐batch repeatability. Herein, a pair of regioisomeric SMDs (BT‐O1 and BT‐O2) has been synthesized with alkoxy groups as S···O noncovalently conformational locks (NoCLs) at the inner and outer position, respectively. Theoretical and experimental results reveal that the regioisomeric effect has a significant influence on the light‐harvest ability, energy levels, molecular geometries, internal reorganization energy, and packing behaviors for the two SMDs. As a result, BT‐O2‐based binary device shows an impressive PCE of 13.99%, much higher than that of BT‐O1 based one (4.07%), due to the better‐aligned energy level, more balanced charge transport, less charge recombination, lower energy loss, and more favorable phase separation. Furthermore, the fullerene derivative PC71BM is introduced into BT‐O2:H3 as the third component to achieve a notable PCE of 15.34% (certified 14.6%). Overall, this work reveals that NoCLs is a promising strategy to achieve high‐performance SMDs for all‐small‐molecule OSCs.

AbstractSensor‐integrated wound dressings are emerging tools applicable to a wide variety of medical applications from emergency triage to at‐home monitoring. Uncomfortable, unnecessary wound dressing changes may be avoided by providing quantitative insight into tissue characteristics related to wound healing such as tissue oxygenation, pH, and exudate/transudate volume. Here, a simple cost‐effective methodology for quantifying oxygen and pH in a swellable hydrogel dressing using a single photograph is presented. The red and green luminescence of a novel dendritic polyamine Pt‐porphyrin and fluorescein conjugate quantitatively responds to oxygen and pH, respectively, and enables robust sensing. The porphyrin conjugate, when combined with a four‐arm star polyethylene glycol (PEG) amine polymer, rapidly crosslinks at room temperature with an N‐hydroxysuccinimide (NHS)‐PEG crosslinker to form a color‐changing hydrogel dressing with tunable swelling capabilities applicable to a variety of wound environments. An inexpensive digital single‐lens reflex (DSLR) camera modified with bandpass filters captures the hydrogel luminescence using simple macroscopic photography, and conversion to HSB colorspace allows for intensity‐independent image analysis of the hydrogels' dual modality response. The hydrogel formulation exhibits a robust and validated visible red‐orange‐green “traffic light” spectrum in response to oxygen changes, regardless of swelling state, pH, or autofluorescence from skin, thereby enabling the clinician friendly naked‐eye feedback.

Published: February 2022

AbstractThe harsh urine microenvironment (UME), as an inherent hurdle, endangers and renders urethral repair unreachable. Innovatively, the unfavorable UME is utilized as the design source to construct a UME‐responsive 3D‐printed hydrogel patch for realizing scarless memory repair, wherein laser‐excited reactive oxygen species (ROS) production and mechanical strength elevation using chemically crosslinked silicon quantum dots are accessible. Intriguingly, the proposed composite scaffolds can respond to Ca2+ in urine, cause structure reconfiguration, and repress swelling to further enhance scaffold stiffness. Systematic experiments validate that ROS birth and unexpected stiffness elevation in such UME‐responsive scaffolds can realize scarless memory repair of the urethra in vivo. Comprehensive mechanism explorations uncover that the activations of cell proliferation and collagen‐related genes (e.g., MMP‐1 and COL3A1) and the dampening of fibrosis‐related (e.g., TGF‐β/Smad) and mechanosensitive genes (e.g., YAP/TAZ) are responsible for the scarless memory repair of such UME‐responsive scaffolds via enhancing collagen deposition, recalling mechanical memory, decreasing fibrosis and inflammation, and accelerating angiogenesis. The design rationales (e.g., UME‐initiated structure reconfiguration and antiswelling) can serve as an instructive and general approach for urethra repair.
Synthesis, Photophysical and Electrochemical Study of 1,3,6,8‐Tetraarylsubstituted X‐Shaped Phenanthrene Derivatives
Authors: Nishida Jun‐Ichi , Matsuno Kouhei , Kawase Takeshi 
Published: February 2022

AbstractX‐shaped phenanthrene derivatives containing aryl substituents at the 1,3,6,8‐positions were synthesized through Suzuki coupling reactions of two types of phenanthrenes possessing bromine and chlorine substituents. X‐shaped phenanthrenes, with four t‐butylphenyl, 9,9‐dimethyl‐9H‐fluoren‐2‐yl or 4‐diphenylaminophenyl (DPAP) groups, are highly emissive in the blue region and their fluorescence efficiencies increase as the extent of aryl π‐conjugation increases. To assess the effects of donor (D) and acceptor (A) groups at the 1,8‐ and 3,6‐positions on intramolecular charge‐transfer emission, two D−A compounds with two DPAP D‐groups and two 4‐pyridyl (Py) A‐groups were synthesized. Results of electrochemical studies reveal that the phenanthrene with four DPAP groups does not undergo oxidative polymerization in dichloromethane, but the two D−A analogs possessing both DPAP and Py groups do undergo oxidative polymerization, producing films which have electrochromic properties.
Beyond transcortical channels, a supraparietal vascular plexus: A newly recognized anatomical feature
Authors: Rothschild Bruce , Scott Elizabeth 
Published: February 2022

AbstractSurvey of transcortical channels across mammalian phylogeny exposes a previously unrecognized phenomena, localized to the most caudal third of aSus scrofaparietal. The current study is performed to assess the nature, ontogeny and phylogenetic distribution of this phenomenon. Dissection of a freshS. scrofais performed to characterize the nature of these structures and assess the relationship of the phenomenon to overlying tissues. The external surface of the parietal region of the skulls of recent Artiodactyla, Perissodactyla, Lagomorpha, and Rodentia and PleistocenePlatygonus compressusare systematically examined by surface microscopy. Dissection of the parietal region of aS. scrofahead revealed a structure localized to the most caudal third of the parietal bone. It is composed of anastomosing blood vessels interposed between the dermis and bone. The phenomenon is present among Artiodactyla in all examined Suidae and Tayassuidae, but limited among Cervidae toOdocoileusand apparently limited among Perissodactyla to Tapiridae, both extant and extinct and independent of sex and age. A previously undescribed anatomic structure is observed during survey of transcortical parietal circulation. There is connection between the structure and parietal diploic vessels. Interpreted as a vascular plexus, the possibility of a countercurrent system for brain thermoregulation is considered.

AbstractAnatomical science is a fundamental element of undergraduate medical education; thus, it is imperative that the course serves future medical professionals when entering clinical practice. However, anatomical education has faced challenges in recent years including decreased allocated time, increased class sizes and over‐stretched staff. Technological advancements in anatomical education may provide relief to these issues. Therefore, exploring clinicians' perspective on the clinical relevance and efficacy of anatomical education, within an African context, can inform its future. This study used a qualitative research approach within an interpretive paradigm. Eight semi‐structured one‐on‐one interviews were conducted with clinicians associated with Stellenbosch University and Tygerberg Hospital. Thematic analysis was employed to analyze the data, creating themes and codes. Trust worthiness of the data was ensured through peer debriefing and member checking. Results reveal that clinicians find clinically relevant anatomy valuable to students. However, some feel that this is not delivered effectively at present. Clinicians see potential for the incorporation of clinical technologies into anatomical pedagogy. Although clinicians are hopeful for new technological developments in anatomical education, concerns were reported about its autonomous nature. This study concludes that although clinically relevant anatomical education is beneficial to students, the time and the resources via which it is delivered should be considered. There is optimism for the future of anatomical education with the advancements of technologically based educational resources, however, new resources should be incorporated with planning and supervision.
Anisotropic Thermal Characterisation of Large‐Format Lithium‐Ion Pouch Cells**

Published: February 2022

AbstractTemperature strongly impacts battery performance, safety and durability, but modelling heat transfer requires accurately measured thermal properties. Herein we propose new approaches to characterise the heat capacity and anisotropic thermal‐conductivity components for lithium‐ion pouch cells. Heat capacity was estimated by applying Newton's law of cooling to an insulated container within which the cell was submerged in warmed dielectric fluid. Thermal conductivity was quantified by heating one side of the cell and measuring the opposing temperature distribution with infra‐red thermography, then inverse modelling with the anisotropic heat equation. Experiments were performed on commercial 20 Ah lithium iron phosphate (LFP) pouch cells. At 100 % state‐of‐charge (SOC), the heat capacity of a 489 g, 224 mL pouch cell was 541 J K−1. The through‐plane and in‐plane thermal conductivities were respectively 0.52 and 26.6 W m−1 K−2. Capturing anisotropies in conductivity is important for accurate thermal simulations. State‐of‐charge dependence was also probed by testing at 50 % SOC: the heat capacity dropped by 6 % and thermal conductivity did not significantly change.

AbstractBackgroundUsing data from the global burden of disease (GBD) between 1990 and 2019 to report the leading etiological factors and hazards for liver cancer by HBV (LCHB), HCV (LCHC), alcoholic use (LCAL), NASH (LCNA), and other causes (LCOT).MethodThe estimated annual percentage change (EAPC) and age‐standardized incidence rate (ASR) in different districts, sex, and age are used to quantify the change of etiologies of liver cancer. Age‐period‐cohort models were performed to predict the primary liver cancer incidence and case numbers.ResultsBased on the GBD database of the whole world for the five etiologies of liver cancer in 2019, the percentage of incidence of LCAL, LCHB, LCHC, LCNA, and LCOT are 18.4%, 41%, 28.5%, 6.8%, and 5.3%, respectively. Fiver etiologies of liver cancer show gender differences, with LCHB and LCAL being more prevalent in men, and LCHC, LCNA being more prevalent in women. Besides, live cancer of males is because of alcohol using and smoking, while the reason of liver cancer of females is drug use, high BMI and high fasting plasma glucose. Interestingly, the incidence of LCHC in women over 85 years old, LCNA in women over 75 years old, and LCOT in women over 75 years old were all higher than that in men. According to the future prediction, the incidence rate of liver cancer itself, as well as the five causes of liver cancer, tends to decrease gradually after 2019, while the incidence rate of LCNA in males will continue to increase until 2025.ConclusionsThe incidence of liver cancer has been increasing and its major causes vary considerably at global, regional, or national levels, also vary by gender and age group.
Distancing from the worst or facing the inescapable? Social representations and positioning of people in marginalised groups
Authors: Savonen Jenni , Kataja Kati , Sakki Inari 
Published: February 2022

AbstractThis article draws from a social representations approach (SRA) to present a qualitative inquiry of identity construction in interaction and as part of the social context. We argue that the concept of positioning, inherent to our understanding of SRA, provides a bridge between social representations and identities. Focusing on societally marginalised groups and with illustrative interview samples gathered from two different studies in Finland, this article aims to show how people who use hard drugs position themselves within dominating social representations of ‘addict’, ‘junkie’ and ‘polydrug user’. Two ways of positioning are employed to negotiate with negative social representations: resistance and partial acceptance. ‘Distancing from the worst’ as a way of positioning characterises resistance and illustrates how a positive identity is constructed by describing the ‘ingroup other’ in negative ways, enabling justification of why the responded is not like that. In contrast, ‘facing the inescapable’ as a way of positioning illustrates partial acceptance that is engaged when people feel they cannot control their use or their lives more generally and cannot justify another position than that of a prototypical user. Our article advances the literature on the role of positioning within representational fields as enabling individuals to reject, challenge or accept the dominating social representations, while at the same time serving as a resource to cope with identity threats and maintain a positive identity.

Authors: Güler Osman , Savaş Serkan 
Published: February 2022

AbstractThe Ministry of National Education of Turkey equipped all schools with interactive boards (IBs) within the scope of the FATİH project. The need for appropriate materials has arisen for the effective use of IBs in educational activities. Three‐dimensional (3D) technologies are also among these materials. It has been determined in the study that IBs have the necessary hardware to run stereoscopic 3D (S3D) training materials, but the panel has not got an S3D imaging feature. Therefore, only the anaglyph S3D imaging method can be applied to IBs. Thus, an anaglyph S3D training material was prepared for the interaction of the skeletal system and interactive 3D material design for IBs with its effects in education was investigated. Besides, S3D imaging methods with features of IBs were examined. A Likert‐type scale was developed to measure the usability of the training material on IBs and the material was evaluated by 20 experts. The data were analyzed by the SPSS statistical program and the results were interpreted. According to the results, educational material seems to be positive in terms of image characteristics, content, navigation, and ease of use, font sizes were moderate for readability, the feedback process and the help menu were moderately effective.
