Four lessons learned: Employees' perceptions of fundraising via reward‐based crowdfunding
Authors: van Teunenbroek Claire , Smits Rosa 
Published: April 2023

AbstractAn innovative way to support cultural institutions is through reward‐based crowdfunding, an online funding mechanism for a specific project, which offers donors a reward for their donation. We explored employees' perceptions of crowdfunding and focused on the question: “How do employees of cultural institutions running a crowdfunding campaign perceive the use of crowdfunding to collect funds?” To answer this question, we focus on interpretive research using semi‐structured interviews (n = 15) among Dutch cultural institutions' employees responsible for running the crowdfunding. We used earlier findings on psychological ownership to structure the interviews. Psychological ownership is the feeling that the project has become an employee's extension, and previous research linked it to success on the work floor. Our findings claim four lessons. First, crowdfunding is a full‐time job and not an extra activity. Second, crowdfunding differs from traditional fundraising: it contains specific content‐related tasks they do not perform as fundraisers. Third, crowdfunding asks for teamwork. While autonomy is valued, one employee should not be responsible for the campaign. Fourth, crowdfunding does not come naturally to all cultural institutions. This research provides a basis for further specification of crowdfunding and its implementation in the cultural sector.

AbstractObjectiveThe aim of this study was to clarify the relationships among large for gestational age (LGA) and cardiometabolic risk factors.MethodsPubMed, Web of Science, and the Cochrane Library databases were searched to identify studies on LGA and outcomes of interest, including BMI, blood pressure, glucose metabolism, and lipid profiles. Data were independently extracted by two reviewers. A meta‐analysis was performed using a random‐effects model. The Newcastle‐Ottawa Scale and funnel graph were used to assess the quality and publication bias, respectively.ResultsOverall, 42 studies involving 841,325 individuals were included. Compared with individuals born appropriate for gestational age, individuals born LGA had higher odds of overweight and obesity (odds ratios [OR] = 1.44, 95% CI: 1.31‐1.59), type 1 diabetes (OR = 1.28, 95% CI: 1.15‐1.43), hypertension (OR = 1.23, 95% CI: 1.01‐1.51), and metabolic syndrome (OR = 1.43, 95%; CI: 1.05‐1.96). No significant difference was found in hypertriglyceridemia and hypercholesterolemia. Stratified analyses showed that, compared with individuals born appropriate for gestational age, individuals born LGA had higher odds for overweight and obesity from toddler age to puberty age (toddler age: OR = 2.12, 95% CI: 1.22‐3.70; preschool: OR = 1.81, 95% CI: 1.55‐2.12; school age: OR = 1.53, 95% CI: 1.09‐2.14; puberty: OR = 1.40, 95% CI: 1.11‐1.77).ConclusionsLGA is associated with increased odds of obesity and metabolic syndrome later in life. Future studies should focus on elucidating the potential mechanisms and identifying risk factors.

AbstractObjectiveExcessive gestational weight gain (GWG) has been associated with autism spectrum disorder (ASD). This study sought to examine whether familial susceptibility for autism, intensity of ASD‐related behaviors, or prepregnancy BMI influences the association of GWG with ASD‐related behaviors.MethodsUsing data from the Early Autism Risk Longitudinal Investigation (EARLI) study (n = 136), a familial enriched cohort of mothers who had a previous child with ASD, and the Health Outcomes and Measures of the Environment (HOME) study (n = 253), a general population cohort, gestational age and prepregnancy BMI category‐specific GWG z scores were calculated. Caregivers completed the Social Responsiveness Scale (SRS) to assess the presence and severity of ASD‐related traits in children aged 3 to 8 years. Using quantile regression, the association between GWG z scores and ASD‐related behaviors in children was estimated.ResultsIn HOME, among mothers who had overweight or obesity prepregnancy BMI values, GWG z scores and SRS scores were positively associated in children with more ASD‐related traits (higher SRS scores), but not in children with fewer ASD‐related traits. Similar patterns were observed in EARLI among mothers with prepregnancy obesity.ConclusionsGWG may be associated with autism‐related behaviors among children who have a greater predisposition to these behaviors and who have mothers with prepregnancy overweight or obesity.

Published: April 2023

AbstractAdditive manufacturing (AM) is being used more widely because of the simplicity of the operating procedures. It decreases material consumption during part production and eliminates material waste. Fused deposition modeling (FDM), a well‐known AM process, uses thermoplastic polymer as a feedstock to manufacture the end design. Pure thermoplastic‐based products are still utilized as prototypes in several sectors due to their lack of strength and durability. This problem has been solved by strengthening the thermoplastics by adding a reinforcing element. Composites are made of polymers and various constituents known as reinforcing components. This article overviews natural reinforced polymer composites used in the FDM process. Mechanical and Thermal properties are presented based on natural filler percentage, and this article only considered natural composite filaments for the FDM process.

Published: April 2023

AbstractThe main obstacles for the commercial application of Lithium–Sulfur (Li–S) full batteries are the large volume change during charging/discharging process, the shuttle effect of lithium polysulfide (LiPS), sluggish redox kinetics, and the indisciplinable dendritic Li growth. Especially the overused of metal Li leads to the low utilization of active Li, which seriously drags down the actual energy density of Li–S batteries. Herein, an efficient design of dual‐functional CoSe electrocatalyst encapsulated in carbon chain‐mail (CoSe@CCM) is employed as the host both for the cathode and anode regulation simultaneously. The carbon chain‐mail constituted by carbon encapsulated layer cross‐linking with carbon nanofibers protects CoSe from the corrosion of chemical reaction environment, ensuring the high activity of CoSe during the long‐term cycles. The Li–S full battery using this carbon chain‐mail catalyst with a lower negative/positive electrode capacity ratio (N/P < 2) displays a high areal capacity of 9.68 mAh cm−2 over 150 cycles at a higher sulfur loading of 10.67 mg cm−2. Additionally, a pouch cell is stable for 80 cycles at a sulfur loading of 77.6 mg, showing the practicality feasibility of this design.

AbstractHydrogen energy is regarded as the ultimate energy source for future human society, and the preparation of hydrogen from water electrolysis is recognized as the most ideal way. One of the key factors to achieve large‐scale hydrogen production by water splitting is the availability of highly active and stable electrocatalysts. Although non‐precious metal electrocatalysts have made great strides in recent years, the best hydrogen evolution reaction (HER) electrocatalysts are still based on noble metals. Therefore, it is particularly important to improve the overall activity of the electrocatalysts while reducing the noble metals load. Alloying strategies can shoulder the burden of optimizing electrocatalysts cost and improving electrocatalysts performance. With this in mind, recent work on the application of noble metal‐based alloy electrocatalysts in the field of hydrogen production from water electrolysis is summarized. In this review, first, the mechanism of HER is described; then, the current development of synthesis methods for alloy electrocatalysts is presented; finally, an example analysis of practical application studies on alloy electrocatalysts in hydrogen production is presented. In addition, at the end of this review, the prospects, opportunities, and challenges facing noble metal‐based alloy electrocatalysts are tried to discuss.

AbstractThe starch yield of 23–28% (db) with 35–43% amylose content is recovered from different immature apple varieties. Scanning electron microscopy reveals the presence of the dome to spherical shaped granules of 3.1–11.62 µm size. The transition temperatures, onset temperature, peak temperature, conclusion temperature, and enthalpy of gelatinization are calculated using differential scanning calorimetry (DSC) ranges between 61.62 and 64.48 °C, between 64.61 and 68.07 °C, between 68.64 and 72.37 °C, and between 4.35 and 17.49 J g−1, respectively. The water absorption capacity and oil absorption capacity of starches range between 1.036 and 1.372 mL g−1 and between 0.876 and 1.125 mL g−1, respectively. The peak viscosity of 638–1942 cP is achieved in 3.8–6.10 min at a pasting temperature of 65–71 °C. A yield stress of 10–39 Pa is sufficient to instigate the Herschel Bulkley flow. The paste of Mollie's Delicious starch is more structured and elastic; its gel has a hardness of 3.5 N and maximum recovery strength.
Performance‐based approach in model code 2020: Working on future‐oriented standardization
Authors: Bigaj‐van Vliet Agnieszka , Matthews Stuart 
Published: April 2023

AbstractThe vision for fib MC2020 is to go beyond the point reached by fib MC2010, recent ISO codes, such as ISO 16311, and the current Eurocode activities to extend the application of Eurocodes to existing structures. The contents of fib MC2020 suit these forward‐looking objectives, dealing both with the design of new structures and all the activities associated with the life‐cycle management of existing concrete structures including matters, such as in‐service assessment and interventions upon them, including situations where new structural members are incorporated as parts of existing structures. With the fib MC2020 adaptations taking sustainability as a fundamental requirement, defining implications for subsidiary performance requirements critical to structural design and assessment procedures, it is logical that Model Code 2020 explicitly introduces and consequently seeks to make use of performance‐based concepts. A focus on performance provides a potential way to better align the interests of owners, users, technical consultants (such as structural engineers, material engineers, etc.), contractors, as well as material suppliers and manufacturers. It is envisaged that implementing the concept of the performance‐based approach in design and assessment will encourage rational design and technological progress which will facilitate the creation of superior structures for future generations, by removing constraints to the use of novel types of concrete and reinforcing materials and offering possibilities for optimization of solutions that better fit the needs of stakeholders. This paper addresses the principles of the performance‐based approach to design and assessment and discusses the manner in which it has been introduced in fib MC2020. The benefits and burdens associated with the performance‐based approach and the traditional prescriptive approach to engineering specification are discussed, both from a technical and process/commercial/contractual point of view, to describe the overall benefits of the performance‐based approach. Finally, the future outlook for a coherent integration of the performance‐based approach in design and assessment is addressed, paving the way for further work on standardization for sustainable concrete structures.
The effect of graphene oxide on dune sand cementitious composites reflected in enhancing freeze–thaw resistance: An experimental study

Published: April 2023

AbstractTo advance the utilization of dune sand, a sustainable albeit flawed resource, for structural engineering, the incorporation of graphene oxide (GO) is suggested as a potential means for improving durability of dune sand cementitious composites (DSCC). In this study, DSCC samples with varying GO concentrations were prepared. The effect of GO on the freeze–thaw resistance of DSCC was then studied by freeze–thaw cyclic test and mechanical test. In addition, to elucidate the mechanism underlying the observed enhancement in freeze–thaw resistance due to GO incorporation, thermogravimetric, mercury injection, adsorption, and morphological analyses were performed. The experimental results showed that incorporating GO into DSCC can enhance its freeze–thaw resistance without compromising its mechanical properties. The weight loss and relative dynamic modulus of elasticity of the specimen with 0.06 wt% GO decreased by 92.83% and 64.96%, respectively, as well as the compressive strength increased by 22.76% after 150 freeze–thaw cycles compared with the control specimen. The enhancing effect of adding GO on the freeze–thaw resistance of DSCC was found to be attributed to the promotion of hydration and the control of internal structure. Notably, the modification of GO on the smooth dune and the reinforcement of GO on the interface between dune sand particles and cement matrix was identified, which may be the new evidence for testifying the GO enhancement on the freeze–thaw resistance of dune sand cementitious composites.

Published: April 2023

AbstractCarbamoyl fluorides, fluoroformates, and their analogues are a class of important compounds and have been evidenced as versatile building blocks for the preparation of useful molecules in organic chemistry. While major achievements were made in the synthesis of carbamoyl fluorides, fluoroformates, and their analogues in the last half of 20th century, an increasing number of reports have focused on using O/S/Se=CF2 species or their equivalents as the fluorocarbonylation reagents for the direct construction of these compounds from the parent heteroatom‐nucleophiles in recent years. This review mainly summarizes the advances in the synthesis and typical application of carbamoyl fluorides, fluoroformates, and their analogues by the halide exchanges and fluorocarbonylation reactions since 1980.

Published: April 2023

AbstractEnamines are formed by reacting a carbonyl compound with an amine under dehydration conditions. A vast array of transformations has been achieved via preformed enamine chemistry. Recently, by introducing conjugating double bonds to the enamine functionality, dienamines, and trienamines have propelled the discovery of several previously unattainable remote‐site functionalization reactions of carbonyl compounds. Comparatively, alkyne‐conjugating enamine analogues have recently shown high potential in multifunctionalization reactions while remaining underexplored. In this account, we systematically summarized and discussed recent advances in synthetic transformations based on ynenamine‐containing compounds.

Published: April 2023

AbstractIn recent years, the demand for quantifying the five senses has increased in the industrial and medical fields. In particular, the sense of touch is a complex sensation consisting of contact force, sliding force, and cold‐warm sensation. The cold‐warm sensation is perceived by the difference in heat transfer between the object and the skin, and the difference in the heat capacity of the object. In our previous research, we developed a MEMS tactile sensor that can measure contact force, sliding force, and cold‐warm sensation with a single sensor. However, the measurement of the cold‐warm sensation requires a long measurement time to stabilize the temperature and relatively high‐temperature conditions of 40°C or higher. In this study, we report on a method for measuring the cold‐warm sensation at a temperature similar to that of a human fingertip. © 2023 Institute of Electrical Engineers of Japan.

Published: April 2023

AbstractBackgroundIn this study, the role of autophagy in hepatic fibrosis and its effects on macrophage polarization and exosomes (EVs) were verified by establishing hepatic fibrosis model and co‐culture model, providing evidence for treatment.MethodsIn this study, CCL4 was used to establish hepatic fibrosis model. The morphology and purity of exosomes (EVs) were verified by transmission electron microscopy, western blotting (WB), and nanoparticle tracing analysis (NTA). Real‐time quantitative PCR (qRT‐PCR), WB and enzyme‐linked immunoadsorption (ELISA) were used to detect hepatic fibrosis markers, macrophage polarization markers and liver injury markers. Histopathological assays were used to verify the liver injury morphology in different groups. The cell co‐culture model and hepatic fibrosis model were constructed to verify the expression of miR‐423‐5p.ResultsHepatic fibrosis model showed that CCL4 promoted early autophagy increase but inhibited autophagy flux in liver. mRFP‐GFP‐LC3 detection showed that both LPS group and Baf group inhibited autophagy flux. This inhibitory effect was reversed by Rap combination therapy. The M1/M2 markers of macrophage polarization were further tested, and it was found that LPS and Baf could promote M1 polarization and inhibit M2 polarization. Rap processing reverses this phenomenon. These data suggest that autophagy can regulate the polarization process of liver macrophages. WB and NTA showed that LPS induced EVs generation. In addition, LPS‐induced EVs could promote HSC proliferation, cell cycle, migration, and the expression of fibrosis markers. Macrophage‐EVs could affect the fibrosis process of stellate cells through the secretion of miR‐423a‐5p expression. The hepatic fibrosis model was further established to verify the regulation of autophagy and EVs on the fibrosis process.ConclusionThis study was showed that autophagy could regulate fibrosis by promoting HSC activation by regulating macrophage polarization and exosome secretion.

ABSTRACTObjectiveTo assess the effectiveness, cost and cost‐effectiveness of four screening strategies for first‐trimester (T1) cytomegalovirus (CMV) primary infection (PI) in pregnant women in France.MethodsIn a simulated pregnant population of 800 000 (approximate number of pregnancies each year in France), using costs based on the year 2022, we compared four CMV maternal screening strategies: Strategy S1, no systematic screening (current public health recommendations in France); Strategy S2, screening of 25–50% of the pregnant population (current screening practice in France); Strategy S3, universal screening (current medical recommendations in France); Strategy S4, universal screening (as in Strategy S3) in conjunction with valacyclovir in case of T1 PI. Outcomes were total cost, effectiveness (number of congenital infections, number of diagnosed infections) and incremental cost‐effectiveness ratio (ICER). Two ICERs were calculated, comparing Strategies S1, S2 and S3 in terms of euros (€) per additional diagnosis, and comparing Strategies S1 and S4 in € per avoided congenital infection.ResultsCompared with Strategy S1, Strategy S3 enabled diagnosis of 536 more infected fetuses and Strategy S4 prevented 375 congenital infections. Strategy S1 was the least expensive strategy (€98.3m total lifetime cost), followed by Strategy S4 (€98.6m), Strategy S2 (€106.0m) and Strategy S3 (€118.9m). In the first analysis, Strategy S2 was dominated and Strategy S3 led to an additional €38 552 per additional in‐utero diagnosis, compared with Strategy S1. In the second analysis, Strategy S4 led to an additional €893 per avoided congenital infection compared with Strategy S1, and was cost‐saving compared with Strategy S2.ConclusionsIn France, current screening practice for CMV PI during pregnancy is no longer acceptable in terms of cost‐effectiveness because this strategy was dominated by universal screening. Moreover, universal screening in conjunction with valacyclovir treatment would be cost‐effective compared with current recommendations and is cost‐saving compared with current practice. © 2023 The Authors.
