“I’m Very Hurt”: (Un)justly Reading the Black Female Body as Text in a Racial Literacy Learning Assemblage
Authors: Ohito Esther O. 
Published: August 2021

ABSTRACTThere has been a recent rise in research that has attuned to matters of the body in literacy learning. This article is a contribution to that emerging corpus of scholarship. Specifically, the article is a Black feminist narrative inquiry into the undertheorized role of embodiment―and relatedly, the embodied knowing that materializes as emotion or affect―in racial literacy learning. To illustrate, I employed a blend of embodiment, affect, and assemblage theories to examine an episode of a university‐based (self‐described) anti‐racist pedagogue’s racial literacy instruction in an English teacher education program in the United States. A sociomaterial approach to literacy frames my exploration of the relation between the emotions generated during classroom discourse about the contents of a curricular text used by the Black female pedagogue and the reproduction of anti‐racist ideology. Findings underscore that racial literacy instruction is (inter)embodied and affective and that each body is a particular racialized, sexed, gendered, and otherwise marked text. These findings underpin my clarion call for a turn to Black feminist racial literacy instruction, an approach entailing the enactment of reparative and healing pedagogical practices that care‐fully tend to the embodied and psychic wellness of Black women and girls in particular while simultaneously cultivating pedagogues’ and students’ commitments to justice and humanization in English teacher education classrooms.

Endotoxin contamination in ovalbumin as viewed from a nano‐immunotherapy perspective

Published: August 2021

AbstractOvalbumin (OVA) is a model antigen commonly incorporated in smartly designed nanoparticles for delivery into antigen‐presenting cells (APC), aiming to investigate the immune activity and therapeutic efficacy of nanoparticles that contain immunoregulatory compounds. However, the immunoresponse observed in nano‐immunotherapy may unexpectedly arise from endotoxin impurity of OVA in the nanoparticles. Literature review shows that most researchers did not notice the importance of endotoxin‐free OVA when used in nano‐immunotherapy studies. Concentration at as low as 5 μg/ml OVA from Sigma‐Aldrich (contains 0.625 ng/ml endotoxin) was able to activate APC such as dendritic cells and macrophages. Here, we proposed that the endotoxin impurity in OVA or the finished nanoproducts should be determined by both Limulus Amebocyte Lysate (LAL) and cell‐based assay, to ensure the endotoxin‐free quality of the nanoparticles. The endotoxin in OVA can be removed by endotoxin removal column and phase separation methods and endotoxin‐free OVA can be purchased. This perspective alerts the researchers of endotoxin impurity of OVA that may transfer into the finished nanoparticles and introduce an unfavorable immunoregulatory function with false‐positive results. OVA with minimal endotoxin level should be used in nano‐immunotherapy studies to accurately reflect the true effects of nanoparticles on the immune system.This article is categorized under:

Souveränität und Ambition: Die Transformation der Beziehungen im Kontext der Emanzipation Irans, 1964-1967
Authors: Popp Roland 
Published: August 2021

ZusammenfassungArmin Meyers Einschätzung der sich aus der Ablösung des amerikanischen Militärmonopols im Jahr 1966 ergebenden Folgen betonte die langfristigen Vorteile einer Distanzierung vom früheren Patron. Eine unabhängigere iranische Politik vergrößere mittelfristig die Chancen für interne Stabilität in Iran und habe zugleich im Falle einer Rückkehr der Instabilität in der Zukunft den entscheidenden Vorteil, dass die amerikanische Macht nicht automatisch mit dem Ancien Régime identifiziert werden würde. Damit habe Washington die Chance, auch mit einer möglichen Nachfolgeregierung einvernehmliche Beziehungen zu etablieren.

ZusammenfassungIm November 1979 – unmittelbar nach der Besetzung der US-Botschaft und der damit beginnenden Geiselkrise, aber noch vor der sowjetischen Militärintervention in Afghanistan – erhielt der Nationale Sicherheitsberater Zbigniew Brzezinski von seinem militärischen Berater William E. Odom ein Memorandum mit Vorschlägen für eine Neuorientierung der amerikanischen Politik in der Region des Persischen Golfs und gegenüber Iran. Odom benannte den einen zentralen strukturellen Wandel für die Formulierung der US-Strategie: „[…] we have lost Iran for the present.“ Somit müsse es nunmehr das Ziel sein, die unmittelbare Projektion amerikanischer Militärmacht in den Persischen Golf zu ermöglichen. In diesem Sinne schlug er eine ganze Reihe strategischer Neujustierungen vor, unter anderem – anschließend auch umgesetzt – eine auf die Arabische Halbinsel zentrierte US-Politik, also eine Vertiefung der strategischen Beziehungen zu Saudi-Arabien und den anderen arabischen Golfstaaten, sowie Absprachen über permanente bzw. temporäre Nutzung von Stützpunkten in den Staaten dieser Region.
Celestial superamplitude in $$ \mathcal{N} $$ = 4 SYM theory
Authors: Jiang Hongliang 
Published: August 2021

Abstract
Celestial amplitude is a new reformulation of momentum space scattering amplitudes and offers a promising way for flat holography. In this paper, we study the celestial amplitudes in $$ \mathcal{N} $$
N
= 4 Super-Yang-Mills (SYM) theory aiming at understanding the role of superconformal symmetry in celestial holography. We first construct the superconformal generators acting on the celestial superfield which assembles all the on-shell fields in the multiplet together in terms of celestial variables and Grassmann parameters. These generators satisfy the superconformal algebra of $$ \mathcal{N} $$
N
= 4 SYM theory. We also compute the three-point and four-point celestial super-amplitudes explicitly. They can be identified as the conformal correlation functions of the celestial superfields living at the celestial sphere. We further study the soft and collinear limits which give rise to the super-Ward identity and super-OPE on the celestial sphere, respectively. Our results initiate a new perspective of understanding the well-studied $$ \mathcal{N} $$
N
= 4 SYM amplitudes via 2D celestial conformal field theory.
Dirac Integral Equations for Dielectric and Plasmonic Scattering
Authors: Helsing Johan , Rosén Andreas 
Published: August 2021

AbstractA new integral equation formulation is presented for the Maxwell transmission problem in Lipschitz domains. It builds on the Cauchy integral for the Dirac equation, is free from false eigenwavenumbers for a wider range of permittivities than other known formulations, can be used for magnetic materials, is applicable in both two and three dimensions, and does not suffer from any low-frequency breakdown. Numerical results for the two-dimensional version of the formulation, including examples featuring surface plasmon waves, demonstrate competitiveness relative to state-of-the-art integral formulations that are constrained to two dimensions. However, our Dirac integral equation performs equally well in three dimensions, as demonstrated in a companion paper.

ZusammenfassungAm 27.01.2020 wurde in Deutschland der erste Fall mit einer SARS-CoV-2-Infektion diagnostiziert. Für die Beschreibung des Pandemieverlaufs im Jahr 2020 wurden 4 epidemiologisch verschiedene Phasen betrachtet und Daten aus dem Meldesystem gemäß Infektionsschutzgesetz (IfSG) sowie hospitalisierte COVID-19-Fälle mit schwerer akuter respiratorischer Infektion aus der Krankenhaus-Surveillance eingeschlossen.Phase 0 umfasst den Zeitraum von Kalenderwoche (KW) 5/2020 bis 9/2020, in dem vor allem sporadische Fälle <60 Jahre und regional begrenzte Ausbrüche beobachtet wurden. Insgesamt wurden 167 Fälle übermittelt, die vorwiegend mild verliefen. Dem schloss sich in Phase 1 (KW 10/2020 bis 20/2020) die erste COVID-19-Welle mit 175.013 Fällen im gesamten Bundesgebiet an. Hier wurden vermehrt Ausbrüche in Krankenhäusern, Alten- und Pflegeheimen sowie ein zunehmender Anteil an älteren und schwer erkrankten Personen verzeichnet. In Phase 2, dem „Sommerplateau“ mit eher milden Verläufen (KW 21/2020 bis 39/2020), wurden viele reiseassoziierte COVID-19-Fälle im Alter von 15–59 Jahren und einzelne größere, überregionale Ausbrüche in Betrieben beobachtet. Unter den 111.790 Fällen wurden schwere Verläufe seltener beobachtet als in Phase 1. Phase 3 (KW 40/2020 bis 8/2021) war gekennzeichnet durch die zweite COVID-19-Welle in Deutschland, die sich zum Jahresende 2020 auf dem Höhepunkt befand. Mit 2.158.013 übermittelten COVID-19-Fällen und insgesamt deutlich mehr schweren Fällen in allen Altersgruppen verlief die zweite Welle schwerer als die erste Welle. Unabhängig von den 4 Phasen waren v. a. Ältere und auch Männer stärker von einem schweren Krankheitsverlauf betroffen.

Zusammenfassung
Hintergrund
Mitarbeitende in Gesundheitseinrichtungen sind direkt exponiert und damit besonders gefährdet in der anhaltenden COVID-19-Pandemie. Trotz diverser Berichte zu SARS-CoV-2-Infektionszahlen unter Mitarbeitenden deutscher Kliniken sind die Verläufe von COVID-19 bei dieser besonderen Population wenig beschrieben.

Fragestellung
In diesem Kurzbeitrag sollen die Merkmale und Verläufe von Infektionsfällen unter Mitarbeitenden am Universitätsklinikum Hamburg-Eppendorf in der ersten Welle der Pandemie dargestellt werden.

Methoden
Im Zeitraum 01.07.–28.07.2020 wurden 67 vormals positiv auf SARS-CoV‑2 getestete Mitarbeitende via E‑Mail eingeladen, in einem anonymen Onlinefragebogen detaillierte Angaben zum Krankheitsverlauf zu machen; 39 Personen nahmen teil.

Ergebnisse
Die Teilnehmenden (58 %) waren überwiegend ≤ 39 Jahre alt (64 %) und weiblich (70 %). Die meisten berichteten über direkten Patientenkontakt (85 %), inklusive SARS-CoV-2-positiver Patient*innen (62 %). Die Beschwerden hielten im Median 19 Tage an. 85 % berichteten Fatigue, 67 % Geruchs- oder Geschmacksstörungen, 64 % Husten, 62 % Kopfschmerzen und 51 % Kurzatmigkeit. Die Verläufe waren überwiegend mild; 5 % wurden stationär behandelt. 38 % berichteten mehr als 4 Wochen nach Symptombeginn über anhaltende Beschwerden, insbesondere Geruchs- oder Geschmacksstörungen, Fatigue oder Kurzatmigkeit. Diese hatten häufiger Vorerkrankungen berichtet (53 % vs. 12 %, p = 0,010) und im Speziellen einen arteriellen Hypertonus (27 % vs. 4 %, p = 0,062).

Diskussion
COVID-19-erkrankte Gesundheitsarbeitende berichteten trotz regelhafter Kontakte zu SARS-CoV-2-infizierten Patienten zum größten Teil über milde Verläufe. Ein Teil gab allerdings auch nach Monaten noch Symptome an.

Published: August 2021

AbstractEndoscopic management of umbilical and incisional hernias has adapted to the limitations of conventional laparoscopic instruments over the past 30 years. This includes the development of meshes for intraperitoneal placement (intraperitoneal onlay mesh, IPOM), with antiadhesive coatings; however, adhesions do occur in a significant proportion of these patients. Minimally invasive procedures result in fewer perioperative complications, but with a slightly higher recurrence rate. With the ergonomic resources of robotics, which offers angled instruments, it is now possible to implant meshes in a minimally invasively manner in different abdominal wall layers while achieving morphologic and functional reconstruction of the abdominal wall. This video article presents the treatment of ventral and incisional hernias with mesh implantation into the preperitoneal space (robot-assisted transabdominal preperitoneal ventral hernia repair, r‑ventral TAPP) as well as into the retrorectus space (r-Rives and robotic transabdominal retromuscular umbilical prosthetic repair, r‑TARUP, respectively). The results of a cohort study of 118 consecutive patients are presented and discussed with regard to the added value of the robotic technique in extraperitoneal mesh implantation and in the training of residents.
A Potential Risk Index Dataset for Landfalling Tropical Cyclones over the Chinese Mainland (PRITC dataset V1.0)

Published: August 2021

AbstractA dataset entitled “A potential risk index dataset for landfalling tropical cyclones over the Chinese mainland” (PRITC dataset V1.0) is described in this paper, as are some basic statistical analyses. Estimating the severity of the impacts of tropical cyclones (TCs) that make landfall on the Chinese mainland based on observations from 1401 meteorological stations was proposed in a previous study, including an index combining TC-induced precipitation and wind (IPWT) and further information, such as the corresponding category level (CAT_IPWT), an index of TC-induced wind (IWT), and an index of TC-induced precipitation (IPT). The current version of the dataset includes TCs that made landfall from 1949–2018; the dataset will be extended each year. Long-term trend analyses demonstrate that the severity of the TC impacts on the Chinese mainland have increased, as embodied by the annual mean IPWT values, and increases in TCinduced precipitation are the main contributor to this increase. TC Winnie (1997) and TC Bilis (2006) were the two TCs with the highest IPWT and IPT values, respectively. The PRITC V1.0 dataset was developed based on the China Meteorological Administration’s tropical cyclone database and can serve as a bridge between TC hazards and their social and economic impacts.

AbstractCollisions between wildlife and aircraft are a serious and growing threat to aviation safety. Understanding the frequency of these collisions, the identity of species involved, and the potential damage that can be inflicted on to aircraft aid mitigation efforts by airfield managers. A record of all animal carcasses recovered from Dublin International Airport, Ireland’s largest civil aviation airport, has been maintained since 1990 where strikes with the endemic Irish hare (Lepus timidus hibernicus), a protected subspecies of mountain hare, are of particular concern despite substantial management efforts from the airfield authority. The first strike event with a hare was recorded in 1997, and strike events have substantially increased since then, with a sharp increase recorded in 2011. Over a 30-year period, a total of 320 strike events with the Irish hare have been recorded at the airfield. To date, no strike event with a hare has resulted in damage to an aircraft. However, carcasses can present as a major attraction to avian scavenger species in addition to posing as a risk of causing foreign object damage in the event of an undetected carcass. Hare strikes are discussed in the context of the rate of civil aircraft movements, possible direct and indirect damage to aircraft, and airfield wildlife hazard management. Here, we demonstrate that not only are strike events increasing by 14% on an annual basis, but that the kinetic energy of such an event has the potential to cause significant damage to an aircraft.
Threshold, budget and deadline: beyond the discourse of climate scarcity and control
Authors: Asayama Shinichiro 
Published: August 2021

AbstractSince its inception, the Intergovernmental Panel on Climate Change (IPCC) has always been at the centre of the global climate debate. Its authoritative reports provide cultural resources for public understanding on the challenge of climate change. While the IPCC maintains its perception as a policy-neutral adviser, the IPCC in practice acts as a powerful discursive agent that guides policy debates in a certain direction by enacting influential scientific concepts. These concepts include three prominent metaphors—temperature threshold, carbon budget and climate deadline—that have been widely circulated across science, policy and advocacy. Three metaphors differ on ways in which the risk of climate change is expressed in terms of space and time. But they all constitute the discourse of climate scarcity—the cognitive view of that we have (too) little space and time to stay below a physical limit for avoiding dangerous climate change. This discursive construction of physical scarcity on climate change has significant political and psychological implications. Politically, the scarcity discourse has the risk of increasing a post-political tendency towards managerial control of the global climate (‘scarcity of politics’). Psychologically, however, scarcity has a greater risk of generating a ‘scarcity mindset’ that inhibits our cognitive capacity to imagine human life beyond managing physical scarcity. Under a narrow mindset of scarcity, the future is closed down to the ‘point of no return’ that, if crossed, is destined to be the end. To go beyond the scarcity discourse, a new discourse of emancipation has to be fostered. Climate change can be reframed not as a common single destination but as a predicament for actively reimagining human life. Such a narrative can expand our imaginative capacity and animate political action while embracing social losses.

AbstractAnxiety sensitivity (AS) is implicated in the development and maintenance of several psychopathological conditions. Non-clinical individuals with high autistic traits may develop anxiety disorders and depressive symptoms. Here, we investigated the relationships of autistic traits with AS dimensions and depression, considering sex. We referred to the two-factor model of the autism spectrum quotient to distinguish social and non-social autistic traits and assessed 345 university students on AS and depression scales. Results showed that only social autistic traits predicted general AS and anxiety-related concerns regarding social and cognitive domains. The present results emphasize the need of assessing multiple domains of anxiety in individuals on the autistic spectrum, differentiating social and non-social traits.

AbstractWe study a multi-group version of the mean-field Ising model, also called Curie–Weiss model. It is known that, in the high-temperature regime of this model, a central limit theorem holds for the vector of suitably scaled group magnetisations, that is, for the sum of spins belonging to each group. In this article, we prove a local central limit theorem for the group magnetisations in the high-temperature regime.
Can Ethical Political Leadership Restore Public Trust in Political Leaders?
Authors: Mozumder N. A. 
Published: August 2021

AbstractThis article presents findings from a qualitative study (via in-depth interviews with 121 local political leaders from 65 local authorities in the UK) that aims to understand how ethical leadership practices can restore public trust in political leaders. The study finds that being a moral person, an ethical political leader sets good examples of behaviour, sets the tone at the top and challenges those who do not behave ethically, as well as encourages, supports and rewards those who perform and conduct themselves well. As a result, the level of public trust in political leaders is likely to increase gradually.
Critical Review of Electro-kinetic Remediation of Contaminated Soils and Sediments: Mechanisms, Performances and Technologies

Published: August 2021

AbstractRemediation of contaminated soil and sediment is important for improving the eco-environmental quality. Electro-kinetic remediation (EKR) is an environmentally friendly technology to migrate and remove pollutants from the soil and sediment matrix. This paper analyses the mechanism and performance of EKR of heavy metals, organic pollutants, and compound pollutants. Moreover, the effect of optimizing individual EKR through soil and sediment pre-treatment (adding acid/oxidant/co-solvent/surfactant, stirring, heating, etc.), electrode optimization (exchange electrode, anode approximation, electrode matrix, etc.), and applying multi-technology combination (electro-kinetic permeable reaction barrier/Fenton/ion, exchange membrane/ultrasonic/electrolyte enhancement, etc.) was evaluated. Factors including incomplete separation of pollutants, variation in physico-chemical properties and microstructure of soil/sediment, and difficulties in in situ practice have restrained the field application of EKR. To solve the above technical challenge, an integrated EKR technology based on pollutant in situ separation, followed by separated contaminant treatment, and subsequent valuable elements recovery is proposed.
