Competition, Contracts, and Creativity: Evidence from Novel Writing in a Platform Market
Authors: Wu Yanhui , Zhu Feng 
Published: March 2022

A growing number of people today are participating in the gig economy, working as independent contractors on short-term projects. We study the effects of competition on gig workers’ effort and creativity on a Chinese novel-writing platform. Authors produce and sell their works chapter by chapter under a revenue-sharing or pay-by-the-word contract with the platform. Exploiting a regulation that induced a massive entry of novels in the romance genre but not other genres, we find that, on average, intensified competition led authors to produce content more quickly, whereas its effect on book novelty was weak. However, revenue-sharing books responded to competition substantially more than pay-by-the-word books, particularly regarding novelty. Moreover, the effect of competition on novelty is considerably stronger for books at earlier stages of the product life cycle. Finally, the platform increased the promotion of contracted books, which disproportionately favored pay-by-the-word books. We discuss the implications of these results for creative workers, platform firms, and policy makers in the gig economy. This paper was accepted by Anandhi Bharadwaj, information systems.

Broadband NIR-emitting Te cluster-doped glass for smart light source towards night-vision and NIR spectroscopy applications

Published: March 2022

Broadband near-infrared (NIR)-emitting materials are crucial components of the next generation of smart NIR light sources based on blue light-emitting diodes (LEDs). Here, we report a Te cluster-doped borate glass, which exhibits ultra-broadband emission around 980 nm with a full-width at half-maximum (FWHM) of 306 nm under blue light excitation. We propose adjustments of glass chemistry and processing condition as a means for topo-chemical tailoring of the NIR photoemission characteristics in such materials. Through implementing strongly reducing conditions during glass melting, Te clusters with broad NIR photoluminescence can be generated and stabilized once the melt is vitrified to the glassy state. Tunability of the NIR emission peak over the wavelength range of 904 to 1026 nm is possible in this way, allowing for fine adjustments of spectral properties relative to the stretching vibrations of common chemical bonds, for example, in water, proteins, and fats. This potentially enables high sensitivity in NIR spectroscopy. We further demonstrate potential application of glass-converted LEDs in night vision.

Tracing a resonance frequency of a high quality factor (Q) optical cavity facilitates subpicometer displacement measurements of the optical cavity via Pound–Drever–Hall (PDH) locking scheme, tightly synchronizing a laser frequency to the optical cavity. Here we present observations of subfemtometer displacements on a ultrahigh-Q single-crystal

The effect of cognitive function and central nervous system depressant use on mortality—A prospective observational study of previously hospitalised older patients
Authors: Siddiqui Tahreem Ghazal , Bjelkarøy Maria Torheim , Cheng Socheat , Kristoffersen Espen Saxhaug , Grambaite Ramune , Lundqvist Christofer 
Published: March 2022

BackgroundOlder patients are often users of prolonged Central Nervous System Depressants (CNSD) (Z-hypnotics, benzodiazepines and opioids), which may be associated with reduced cognition. The long-term effects of CNSD use and reduced cognitive function in older patients are unclear. The aim of this study was to examine whether cognitive function and CNSD use at baseline hospitalisation were associated with all-cause mortality two years after discharge.MethodsWe conducted a prospective observational study, including baseline data (2017–2018) from previously hospitalised older patients (65–90 years), assessing all-cause mortality two years after discharge. We used logistic regression to assess the primary outcome, all-cause mortality two years after baseline hospitalisation. The primary predictors were cognitive function measured by The Mini Mental State Examination (MMSE) and prolonged CNSD use (continuous use ≥ 4 weeks). Adjustment variables: age, gender, education, the Hospital Anxiety and Depression Scale (HADS) and the Cumulative Illness Rating Scale for Geriatrics (CIRS-G), using receiver operating characteristics (ROC) to compare the predictive power of the models. In a sub-analysis we used, the Neurobehavioural Cognitive State Examination (Cognistat) and the Clock Drawing Test.ResultsTwo years after discharge, out of 246 baseline patients, 43 were deceased at follow-up, among these 27 (63%) were CNSD users, and 16 (36%) were non-users at baseline, (p = 0.002). In the multivariable models cognitive function (MMSE score) was a predictor of mortality (OR 0.81 (95% CI 0.69; 0.96), p = 0.014). CNSD use was associated with mortality (OR 2.71 (95% CI 1.06; 6.95), p = 0.038), with ROC AUC: 0.74–0.77 for these models. Results using Cognistat supported the findings. The Clock Drawing Test was not significant predictor of mortality.ConclusionTwo years after discharge from the hospital, older patients with reduced cognitive function and CNSD use during hospital stay had higher mortality. This underlines that inappropriate (prolonged and concurrent) use of CNSDs should be avoided by older patients, particularly in patients with reduced cognitive function.Trial registrationNCT03162081, 22 May 2017.
A systematic review on integrated care for traumatic brain injury, mental health, and substance use
Authors: Chan Vincy , Toccalino Danielle , Omar Samira , Shah Riya , Colantonio Angela 
Published: March 2022

Traumatic brain injuries (TBI) and mental health or substance use disorders (MHSU) are global public health concerns due to their prevalence and impact on individuals and societies. However, care for individuals with TBI and MHSU remains fragmented with a lack of appropriate services and supports across the continuum of healthcare. This systematic review provided an evidence-based foundation to inform opportunities to mobilize and adapt existing resources to integrate care for individuals with TBI and MHSU by comprehensively summarizing existing integrated activities and reported barriers and facilitators to care integration. MEDLINE, EMBASE, PsycINFO, CINAHL, Cochrane Central Register of Controlled Trials, Sociological Abstracts, and Dissertations & Theses Global were independently reviewed by two reviewers based on pre-determined eligibility criteria. Data on the integration activity, level and type of integration, reported barriers and facilitators, and the strategies aligning with the World Health Organization’s (WHO) Framework on Integrated Person-Centred Care were extracted to form the basis for a narrative synthesis. Fifty-nine peer-reviewed articles were included, describing treatments (N = 49), programs (N = 4), or screening activities (N = 7). Studies discussing clinical integration at the micro- (N = 38) and meso- (N = 10) levels, service integration at the micro- (N = 6) and meso- (N = 5) levels, and functional integration at the meso-level (N = 1) were identified. A minority of articles reported on facilitators (e.g., cognitive accommodations in treatment plans; N = 7), barriers (e.g., lack of education on cognitive challenges associated with TBI; N = 2), or both (N = 6), related to integrating care. This review demonstrated that integrated TBI and MHSU care already exists across a range of levels and types. Given the finite and competing demands for healthcare resources, cognitive accommodations across treatment plans to facilitate integrated TBI and MHSU care should be considered. Multidisciplinary teams should also be explored to provide opportunities for education among health professionals so they can be familiar with TBI and MHSU.Trial registration:Prospero Registration:CRD42018108343.

Published: March 2022

Background
Acute kidney injury (AKI) in deceased donors is not associated with graft failure (GF). We hypothesize that hemodynamic AKI (hAKI) comprises the majority of donor AKI and may explain this lack of association.

Methods
In this ancillary analysis of the Deceased Donor Study, 428 donors with available charts were selected to identify those with and without AKI. AKI cases were classified as hAKI, intrinsic (iAKI), or mixed (mAKI) based on majority adjudication by three nephrologists. We evaluated the associations between AKI phenotypes and delayed graft function (DGF), 1-year eGFR and GF. We also evaluated differences in urine biomarkers among AKI phenotypes.

Results
Of the 291 (68%) donors with AKI, 106 (36%) were adjudicated as hAKI, 84 (29%) as iAKI and 101 (35%) as mAKI. Of the 856 potential kidneys, 669 were transplanted with 32% developing DGF and 5% experiencing GF. Median 1-year eGFR was 53 (IQR: 41–70) ml/min/1.73m2. Compared to non-AKI, donors with iAKI had higher odds DGF [aOR (95%CI); 4.83 (2.29, 10.22)] and had lower 1-year eGFR [adjusted B coefficient (95% CI): -11 (-19, -3) mL/min/1.73 m2]. hAKI and mAKI were not associated with DGF or 1-year eGFR. Rates of GF were not different among AKI phenotypes and non-AKI. Urine biomarkers such as NGAL, LFABP, MCP-1, YKL-40, cystatin-C and albumin were higher in iAKI.

Conclusion
iAKI was associated with higher DGF and lower 1-year eGFR but not with GF. Clinically phenotyped donor AKI is biologically different based on biomarkers and may help inform decisions regarding organ utilization.

Introduction
Patients with high-consequence infectious diseases (HCID) are rare in Western Europe. However, high-level isolation units (HLIU) must always be prepared for patient admission. Case fatality rates of HCID can be reduced by providing optimal intensive care management. We here describe a single centre’s preparation, its embedding in the national context and the challenges we faced during the severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) pandemic.

Methods
Ten team leaders organize monthly whole day trainings for a team of doctors and nurses from the HLIU focusing on intensive care medicine. Impact and relevance of training are assessed by a questionnaire and a perception survey, respectively. Furthermore, yearly exercises with several partner institutions are performed to cover different real-life scenarios. Exercises are evaluated by internal and external observers. Both training sessions and exercises are accompanied by intense feedback.

Results
From May 2017 monthly training sessions were held with a two-month and a seven-month break due to the first and second wave of the SARS-CoV-2 pandemic, respectively. Agreement with the statements of the questionnaire was higher after training compared to before training indicating a positive effect of training sessions on competence. Participants rated joint trainings for nurses and doctors at regular intervals as important. Numerous issues with potential for improvement were identified during post processing of exercises. Action plans for their improvement were drafted and as of now mostly implemented. The network of the permanent working group of competence and treatment centres for HCID (Ständiger Arbeitskreis der Kompetenz- und Behandlungszentren für Krankheiten durch hochpathogene Erreger (STAKOB)) at the Robert Koch-Institute (RKI) was strengthened throughout the SARS-CoV-2 pandemic.

Discussion
Adequate preparation for the admission of patients with HCID is challenging. We show that joint regular trainings of doctors and nurses are appreciated and that training sessions may improve perceived skills. We also show that real-life scenario exercises may reveal additional deficits, which cannot be easily disclosed in training sessions. Although the SARS-CoV-2 pandemic interfered with our activities the enhanced cooperation among German HLIU during the pandemic ensured constant readiness for the admission of HCID patients to our or to collaborating HLIU. This is a single centre’s experience, which may not be generalized to other centres. However, we believe that our work may address aspects that should be considered when preparing a unit for the admission of patients with HCID. These may then be adapted to the local situations.

Longitudinal Strength Analysis Considering the Cargo Load on Very Large Crude Carrier (VLCC)
Authors: Suci Indah Melati , Sitepu Ganding , Muis Alie Muhammad Zubair 
Published: March 2022

The ultimate strength of the Very Large Crude Carrier (VLCC) is an important aspect that must be analyzed. The purpose of this study was to analyze the ultimate strength of the VLCC ship in terms of deformation under hogging and sagging conditions on the deck and bottom. Deformation is a change in the shape or size of a material due to a workforce that is applied to you. In this case, the deformation in question arises due to the working moment. This deformation analysis was carried out using the Non-Linear Finite Element Analysis (NLFEA) method. This analysis is carried out by presenting the support or Multi-Point Constraints (MPC) in the cross-section, as well as moments of 6.52 × 1012 for hogging conditions and -5.5 × 1012 for slack conditions.
Podmínky k udržitelnému rozvoji na venkově – jak podporovat transformační procesy v praxi?
Authors: Dlouhá Jana , Pospíšilová Marie , Vávra Jan 
Published: March 2022

Východiskem úvah o strategiích udržitelnosti regionálního rozvoje jsou Cíle udržitelného rozvoje (SDGs) a jak se promítají na místní úroveň. Článek soustřeďuje pozornost na cíl č. 4 – vzdělávání, které může významně podporovat implementaci dalších cílů, pokud cílí na důležité aktéry udržitelného rozvoje. Tuto (transformativní) roli by mělo vzdělávání plnit i na místní úrovni, což ovšem strategické rozvojové dokumenty plně nezohledňují, oblast celoživotního učení není systémově řešena vůbec. Cílem výzkumu bylo zmapovat aktuální situaci v regionech ČR a zjistit, jakou úlohu vzdělávání na místní úrovni v kontextu udržitelného rozvoje plní (a mělo by plnit), a jaké jsou v této souvislosti role jednotlivých aktérů rozvoje venkova. Otázky, které si řešitelský tým kladl v rámci školení pro představitele místních akčních skupin (MAS), byly formulovány a následně distribuovány formou plošného dotazníkového šetření mezi manažery/manažerkami MAS. Data byla vyhodnocena kvantitativními a především kvalitativními metodami, s důrazem na jedinečné zkušenosti a postřehy. Z výsledků vyplývá, že místní aktéři (reprezentovaní MAS) si uvědomují potřebu vzdělávání i nedostatky v této oblasti, a chápou též důsledky tohoto stavu pro udržitelný rozvoj v environmentální, ekonomické i sociální oblasti. Potenciál jednotlivých aktérů (jejich role v procesech udržitelnosti) zůstává nevyužit, což ovlivňuje schopnost inovací. Ačkoli jsou MAS aktérem, který svou roli spatřuje především v posilování sociálního kapitálu a dalších předpokladů rozvoje včetně vzdělávání, existují překážky exogenního charakteru, které naplnění této role brání. Součástí možných řešení je posílení leadershipu MAS v otázkách udržitelnosti, a to i prostřednictvím vzdělávání; vytvoření systému celoživotního učení, které využívá místní znalosti; a zapojení expertů nejen v oblasti technologií, ale například též odborníků na otázky sociální. Vymezení rolí jednotlivých aktérů v procesech rozvoje na úrovni regionů (a tím i specifik bottom-up procesů), by přispělo i k vyjasnění toho, jaké top-down podněty jsou nezbytné k prosazování veřejného zájmu, vyjádřeného např. v SDGs.
Catalytic performance of Na/Ca-based fluxes for coal char gasification
Authors: Liu Tao , Mao Lirui , Jiao Facun , Wu Chengli , Zheng Mingdong , Li Hanxu 
Published: March 2022

Abstract
Flux, able to improve the ash fusibility, usually contains catalytic metal compounds. Unfortunately, the quantitative analysis of synergistic catalysis effects between different fluxing agents on coal gasification has not been investigated thoroughly. In this study, the effect of the kinds and content of Na/Ca-based fluxes on char gasification was investigated in thermogravimetry analyzer (TGA). The synergistic catalysis effects and mechanism between the two kinds of fluxes were also studied. Finally, based on the TGA tests, the kinetics models for char gasification with flux addition were developed. The results showed that all the four Na-based fluxes could increase the char reactivity. Na2CO3, which afforded the best activity, could increase the reactivity by 5.3 times when the content was 5%. The five Ca-based fluxes had a weaker catalysis effect compared with Na-based fluxes. CaCl2, exhibiting the best activity among the five Ca-based fluxes, could increase the reactivity by 2.3 times when the content was 5%. For composite fluxes, Na2CO3–CaO and Na2CO3–CaCO3 had a remarkable synergistic effect, whereas others had less effect. Na2CO3 could inhibit the aggregation of Ca, which might cause the synergistic effects between Na and Ca fluxes. The random pore model was more suitable to describe the catalytic gasification process.
Experimental and Theoretical Study on the Performance of an Extruder for Cross-linkable PE
Authors: Harlin A. , Syrjälä S. 
Published: March 2022

Abstract
The performance of a single-screw extruder for the processing of cross-linkable low-density polyethylene in cable coating applications is examined. In particular, the aim is to demonstrate that the melt quality is markedly dependent on the melting efficiency. An instrumented 120 mm, 24 : 1 L/D extruder is used to perform the study. So-called pull-out tests are carried out for investigating the melting behavior inside an extruder. At the beginning of the melting zone, a typical Maddock melting mechanism is observed. Thereafter, as melting proceeds, the solid polymer becomes totally surrounded by melt according to the Lindt-Decker melting mechanism, and finally a solid-bed break-up occurs in many circumstances. This undesirable phenomenon can be avoided by screw cooling which, however, has its own drawbacks. In addition to the experimental work, numerical simulations of the melting behavior are conducted. The results provided by the simulation are in accord with the experimental findings.
Simulation Opportunities by a Three-dimensional Calculation of Injection Moulding based on the Finite Element Method
Authors: Michaeli W. , Hoffmann S. , Kratz M. , Webelhaus K. 
Published: March 2022

Abstract
The simulation of injection moulding is essential to meet quality requirements and to increase the efficiency of the design process. In this paper a 3D-finite element model for the simulation of injection moulding is presented. The model's capability comprises the calculation of velocity, pressure and temperature fields as well as the prediction of the flow front position. The numerical approach is mainly based on the Galerkin formulation. Special emphasis is placed on the handling of polymer compressibility in order to enable a realistic simulation of the packing phase. The numerical efficiency has been largely enhanced through the employment of an automatic time step control. In order to demonstrate the code's capabilities and outline advantages and disadvantages over other simulation systems, the calculation results are compared to experimental data and to results obtained from other numerical models.
