The Relationship Between Basic Needs Satisfaction, Self-determined Motivation, and Burnout in Korean Esports Players
Authors: Hong Hee Jung , Wilkinson Guy , Rocha Claudio M. 
Published: May 2022

AbstractThis article aims to understand the relationship between basic needs satisfaction, self-determined motivation, and burnout in esports players. To achieve this, we investigate three research hypotheses: (1) The three dimensions of basic needs satisfaction have a positive effect on the self-determined motivation of esports players, (2) The self-determined motivation of esports players has a negative effect on their burnout, and (3) All three dimensions of basic needs satisfaction affect esports player’s burnout, indirectly via self-determined motivation. Data were collected through an online questionnaire (n = 608) administered to Korean esports players who play online games as a leisure activity. Results indicate that player competence has a negative relationship with self-determined motivation, suggesting that Korean players do not associate increased levels of competence with their intrinsic motivation. The results show that intrinsic motivation is negatively associated with burnout, particularly exhaustion and reduced sense of accomplishment. It should be noted that Korean players’ high level of competence can result in reduced levels of self-determined motivation, which can lead them to burnout. This should be addressed by the industry, practitioners, and researchers considering the cultural context and the relationship between the factors, which will contribute to the sustainable growth and prosperity of the esports.

AbstractThe Voyager spacecraft have left the heliosphere and entered the interstellar medium, making the first observations of the termination shock, heliosheath, and heliopause. New Horizons is observing the solar wind in the outer heliosphere and making the first direct observations of solar wind pickup ions. This paper reviews the observations of the solar wind plasma and magnetic fields throughout the heliosphere and in the interstellar medium.
Lipid metabolism is dysregulated in a mouse model of diabetes
Authors: Furse Samuel 
Published: May 2022

AbstractMuch evidence for diabetes mellitus being associated with dysregulated lipid metabolism has been accrued from studies using blood plasma. However, the systemic dysregulation these results point to is not understood. This study used Lipid Traffic Analysis on data from a mouse model of diabetes to test the hypothesis that the systemic control of lipid metabolism differed in a model of diabetes. This provided eidence for changes in the systemic control of both triglyceride and phospholipid metabolism that were not attributable to dietary intake. This supports the conclusion that diabetes is a systemic condition associated with dysregulated lipid metabolism through several pathways.
Conservative treatment of fractures involving the coronoid process

Published: May 2022

Abstract
Background
Fractures of the coronoid process require adequate treatment, as otherwise they often lead to chronic instability and the development of rapidly progressive cubital osteoarthritis. Commonly, such patients are treated surgically; however, a defined fraction of patients might benefit from conservative treatment.

Methods
We systematically reviewed the available literature searching Medline using the PubMed interface. The primary objective was to determine indications, treatment protocols, and associated functional outcomes and complications of entirely conservatively treated fractures of the coronoid. The PRISMA guidelines were applied.

Results
We included five studies, all retrospective in design, with a total of 62 patients. For the indication of conservative treatment, joint congruency on imaging was a prerequisite in all studies. This was supplemented on most occasions by dynamic clinical examinations, with a focus on pain, range of motion, and adequate joint stability. Treatment protocols included close-meshed imaging, early functional mobilization, and some form of resting immobilization. Treatment success, defined as excellent or good results according to the Mayo Elbow Performance Score, was 95.1% at an average follow-up of 36 months. Six patients (9.7%) underwent surgical treatment during follow-up; 19 patients (30.6%) suffered complications that did not result in surgery.

Conclusion
The data of this work indicate that most patients achieve satisfactory results following conservative treatment of coronoid fractures caused by rotational moments. Concentric reduction of the joint, clinical exclusion of even mild subluxations, systematic early functional aftercare, and close radiographic monitoring appear to be mandatory requirements. The evidence remains scarce, and conclusions drawn from this review should be viewed with caution, as prospective randomized controlled trials are not available to date.

Samenvatting
Inleiding
Midden door de Rotterdamse wijk Nesselande loopt een hoogspanningslijn. Wonen in de buurt van een hoogspanningslijn geeft mogelijk een verhoogd risico op leukemie bij kinderen. De GGD heeft een rol in de risicocommunicatie aan de inwoners en adviseert de gemeente over dit onderwerp. Uit eerder onderzoek is bekend dat mensen risico’s van straling hoog inschatten en dat vertrouwen in de overheid een rol speelt in de risicoperceptie.

Methode
Dit kwalitatieve onderzoek richt zich op de vraag hoe inwoners van Nesselande het wonen in de buurt van de hoogspanningslijn ervaren in relatie tot hun gezondheid. Er zijn dertien mensen geïnterviewd aan de hand van een topiclijst. Analyse heeft plaatsgevonden door axiale codering.

Resultaten
Deze respondenten schrijven geen gezondheidsklachten aan de hoogspanningslijn toe. Wel zijn er uiteenlopende ideeën en zorgen over mogelijke ziekten die de hoogspanningslijn kan veroorzaken. Alle respondenten geven aan behoefte te hebben aan meer informatie vanuit de gemeente. De GGD is nauwelijks bekend als informatiebron.

Conclusie
Door betere informatievoorziening is gezondheidswinst te behalen. Naast een reëler beeld van de gezondheidseffecten komen openheid en transparantie het vertrouwen in de overheid ten goede. Dat draagt volgens de theorie van de risicoperceptie bij aan het verminderen van het ervaren gezondheidsrisico.
On the antiquity and status of the Spalacidae, new data from the late Eocene of south-East Serbia

AbstractA new blind mole-rat species Debruijnia tintinnabulus nov. sp. is described from the late Eocene of south east Serbia. This find is approximately 10 Ma older than the hitherto oldest records of Spalacidae Vetusspalax and Pannoniamys, both from the late Oligocene of Bosnia and Herzegovina and Serbia. The antiquity of the new species (~34 Ma) is in accordance with recent genetically based age estimates of Spalacidae as an early branch of the Supramyomorpha. A review of the fossil record shows that the Spalacidae are probably not closely related to the Rhizomyinae and Myospalacinae. The spalacid finds from the Paleogene of the Balkans and the Neogene of Anatolia suggests that the family underwent a radiation during the Oligocene involving Debruijnia, Vetusspalax, Pannoniamys and Heramys. During the middle and late Miocene Heramys evolved into a large number of species, here all tentatively allocated to Pliospalax.

Published: May 2022

AbstractThe direct blending of polyether ether ketone (PEEK) with a solid lubricant such as polytetrafluoroethylene (PTFE) improves its tribological performance, but compromises its outstanding mechanical properties and processability. While these negative effects might be circumvented via the hybrid wear method, the influence of the contact temperature between multiple sliding components acting together is not fully understood. Herein, an analytical temperature model considering the influence of both micro- and macro-thermal behavior is extended to predict the contact temperature of a dual-pin-on-disk hybrid wear system. The interactions between several heat sources are investigated and experimentally verified. The analytical results show that the nominal temperature rise of the shared wear track is determined by the combined effect of the heat generated by both pin components, while the rise in flash temperature at the region in contact with each pin component is dependent upon its individual characteristics and working conditions. Hence, while different temperature peaks can coexist in the shared wear track, the maximum value dominates the performance of the system. For the experimentally investigated PEEK-PTFE-steel hybrid wear system, the formation of tribofilms is blocked, and the hybrid wear system fails, when the peak temperature exceeds the glass transition temperature of both pins due to an increase in applied load.
Planning laissez-faire: Supranational central banking and structural reforms
Authors: Braun Benjamin , Carlo Donato Di , Diessner Sebastian 
Published: May 2022

AbstractThe mandate of the European Central Bank (ECB) does not extend to labor market and social policies at the national level. Why, despite the reputational costs, did the ECB act as a staunch advocate of structural labor market reforms from 1999 through 2015? We discuss this question through the theoretical lens of Karl Polanyi’s The Great Transformation. Although Polanyi has been a key reference point for the debate on the social consequences of European economic and monetary integration, one of his key insights has received surprisingly little attention—that central banks have the power to mitigate the impact of international economic integration on domestic social protection. Polanyi regarded central banks—much like trade unions—as national-level institutions of non-market coordination, acting as a protective buffer against the functional pressures of the fixed-exchange-rate monetary regime that was the international gold standard. By contrast, the ECB, as a supranational central bank, embodies these functional pressures. This helps explain why, rather than protecting existing social structures against the logic of the fixed-exchange-rate monetary regime, the ECB has sought to protect the monetary regime by going out of its way to re-shape labor market institutions at the national level.

Background:
Sickle cell disease (SCD) is a wide prevalence disease worldwide. It has a spectrum of clinical manifestations. However, SCD patients are more susceptible to have a serious bacterial infection (SBI) as compared to other individuals.

Objective:
The main objective of this study was to investigate the prevalence rate of serious bacterial infection (SBI) in febrile children with sickle cell disease (SCD), whose vaccinations are up to date and are on regular penicillin prophylaxis, presented to the emergency department (ED) to assist in the management approach of such patients.

Methods:
A retrospective study included febrile SCD children under 12 years of age between 2014 and 2019 at King Saud Medical City (KSMC) in Riyadh, Saudi Arabia. Patients were stratified according to the true culture result of each febrile event. Descriptive statistics were used to report data from the patient's medical records.

Results:
From 833 febrile events, 40 events were assessed for eligibility with positive culture results. Of these, 10 were excluded due to contamination. The rest, 30 children with confirmed SBI (3.6%, 30/833) (95% CI = 2.4%–5.1%) were recruited. The highest prevalence rate of SBI was for urinary tract infection (uti) (2.2%, 19/833) (95% CI = 1.4%–3.5%), followed by bacteremia (1.3%, 11/833) (95% CI = 0.7–2.4), osteomyelitis (0.24%, 2/833) (95% CI = 0.03–0.86) and meningitis (0.12%, 1/833) (95% CI = 0.00–0.67). Pneumococcal was the most common isolate among children with bacteremia (46%, 5/11) followed by Salmonella species (36%, 4/11). All the children fully recovered.

Conclusion:
As the prevalence of SBI, particularly bacteremia, continues to decline with a favorable outcome in our population, ambulatory management practices for well-presented febrile SCD children should be encouraged, for there are no further reasons for admission and the patient can return soon to their hospital if his condition worsens or there is growth in the blood culture. Further effort is needed to determine whether blood culture and empiric antibiotics are necessary for each febrile event in the probable highly active vaccination era.

Published: May 2022

AbstractPurpose:Sleep is essential for our overall health and wellbeing. Unfortunately, stroke often induces insomnia, which has been shown to impede rehabilitation and recovery of function. Cognitive behavioral therapy for insomnia (CBT-I) is the treatment of choice for insomnia in the general population and is efficacious both when delivered face-to-face or online. The primary aim of this study was to evaluate efficacy of blended CBT-I (eCBT-I) in five poststroke participants with insomnia according to DSM-5 criteria.Methods:A randomized multiple baseline design was used to evaluate improvements in total sleep time, sleep onset latency, sleep efficiency, nocturnal awakenings and sleep quality. The intervention included six weeks of eCBT-I combined with two face-to-face sessions.Results:All participants completed the intervention. One participant stopped using the diary, while the other four completed it fully. All five sleep diary measures improved, significantly so for nocturnal awakenings. Moreover, after completion of the treatment, four out of five participants no longer fulfilled DSM-5 criteria for insomnia disorderConclusions:This is the first study to show that blended CBT-I is potentially effective in participants with post-stroke insomnia. The findings justify extension to a randomized controlled trial.
Violent political rhetoric on Twitter
Authors: Kim Taegyoon 
Published: May 2022

AbstractViolent hostility between ordinary partisans is undermining American democracy. Social media is blamed for rhetoric threatening violence against political opponents and implicated in offline political violence. Focusing on Twitter, I propose a method to identify such rhetoric and investigate substantive patterns associated with it. Using a data set surrounding the 2020 Presidential Election, I demonstrate that violent tweets closely track contentious politics offline, peaking in the days preceding the Capitol Riot. Women and Republican politicians are targeted with such tweets more frequently than men and non-Republican politicians. Violent tweets, while rare, spread widely through communication networks, reaching those without direct ties to violent users on the fringe of the networks. This paper is the first to make sense of violent partisan hostility expressed online, contributing to the fields of partisanship, contentious politics, and political communication.

Her chronological account of the careers and activism of these women is not only a major contribution to the history of feminism but also a significant addition to the study of social democracy worldwide.
The Populist Challenge to U.S. Democracy: Renewing American Political Development's Comparative Perspective
Authors: Weyland Kurt 
Published: May 2022

AbstractRegarding the implications of the political developments of the last five years for the study of American political development (APD), this article argues that the unprecedented Trump phenomenon and its problematic repercussions for U.S. democracy have greatly enhanced the value of a comparative perspective, which can draw instructive lessons from the fate of attacks on liberal democracy by populist leaders in other countries. Comparativists examining the contemporary United States initially highlighted the risks of populist leadership (i.e., political agency), stressed the possibilities of democratic backsliding, and examined how popularly elected chief executives can undermine democracy from the inside—all of which fueled grave concerns. Yet for a more realistic assessment of populism's actual danger for U.S. democracy, one must analyze the probability of such a deleterious outcome. Therefore, researchers need to embed agency in contextual conditions and investigate what institutional, structural, cultural, and conjunctural factors empowered populist leaders to destroy democracy in some countries, whereas other constellations of these factors have impeded democratic backsliding in many other nations. With this move beyond a primary focus on agency, comparative analyses align with APD's longstanding attention to complex context factors. Interestingly, such a comparative perspective corroborates the distinctive institutional strengths and relative resilience of U.S. democracy.
Proof-relevance in Bishop-style constructive mathematics
Authors: Petrakis Iosif 
Published: May 2022

AbstractBishop’s presentation of his informal system of constructive mathematics BISH was on purpose closer to the proof-irrelevance of classical mathematics, although a form of proof-relevance was evident in the use of several notions of moduli (of convergence, of uniform continuity, of uniform differentiability, etc.). Focusing on membership and equality conditions for sets given by appropriate existential formulas, we define certain families of proof sets that provide a BHK-interpretation of formulas that correspond to the standard atomic formulas of a first-order theory, within Bishop set theory$(\mathrm{BST})$, our minimal extension of Bishop’s theory of sets. With the machinery of the general theory of families of sets, this BHK-interpretation within BST is extended to complex formulas. Consequently, we can associate to many formulas$\phi$of BISH a set${\texttt{Prf}}(\phi)$of “proofs” or witnesses of$\phi$. Abstracting from several examples of totalities in BISH, we define the notion of a set with a proof-relevant equality, and of a Martin-Löf set, a special case of the former, the equality of which corresponds to the identity type of a type in intensional Martin-Löf type theory$(\mathrm{MLTT})$. Through the concepts and results of BST notions and facts of MLTT and its extensions (either with the axiom of function extensionality or with Vooevodsky’s axiom of univalence) can be translated into BISH. While Bishop’s theory of sets is standardly understood through its translation to MLTT, our development of BST offers a partial translation in the converse direction.
Machine-Learning-Aided Quantification of Area Coverage of Adherent Cells from Phase-Contrast Images
Authors: Rosoff Gal , Elkabetz Shir , Gheber Levi A 
Published: May 2022

Abstract
The advances in machine learning (ML) software availability, efficiency, and friendliness, combined with the increase in the computation power of personal computers, are harnessed to rapidly and (relatively) effortlessly analyze time-lapse image series of adherent cell cultures, taken with phase-contrast microscopy (PCM). Since PCM is arguably the most widely used technique to visualize adherent cells in a label-free, noninvasive, and nondisruptive manner, the ability to easily extract quantitative information on the area covered by cells, should provide a valuable tool for investigation. We demonstrate two cases, in one we monitor the shrinking of cells in response to a toxicant, and in the second we measure the proliferation curve of mesenchymal stem cells (MSCs).
Lifetime of the Outer Solar System Nebula From Carbonaceous Chondrites

Published: May 2022

AbstractThe evolution and lifetime of protoplanetary disks (PPDs) play a central role in the formation and architecture of planetary systems. Astronomical observations suggest that PPDs evolve in two timescales, accreting onto the star for up to several million years (Myr) followed by gas dissipation within ≲1 Myr. Because solar nebula magnetic fields are sustained by the gas of the protoplanetary disk, we can use paleomagnetic measurements to infer the lifetime of the solar nebula. Here, we use paleomagnetic measurements of meteorites to constrain this lifetime and investigate whether the solar nebula had a two‐timescale evolution. We report on paleomagnetic measurements of bulk subsamples of two CO carbonaceous chondrites: Allan Hills A77307 and Dominion Range 08006. If magnetite in these meteorites can acquire a crystallization remanent magnetization that recorded the ambient field during aqueous alteration, our measurements suggest that the local magnetic field strength at the CO parent body location was <0.9 μT at some time between 2.7 and 5.1 Myr after the formation of calcium‐aluminum‐rich inclusions. Coupled with previous paleomagnetic studies, we conclude that the dissipation of the solar nebula in the 3–7 AU region occurred <1.5 Myr after the dissipation of the nebula in the 1–3 AU region, suggesting that protoplanetary disks go through a two‐timescale evolution in their lifetime, consistent with dissipation by photoevaporation and/or magnetohydrodynamic winds. We also discuss future directions necessary to obtain robust records of solar nebula fields using bulk chondrites, including obtaining ages from meteorites and experimental work to determine how magnetite acquires magnetization during chondrite parent body alteration.
