The art of crowdfunding arts and innovation: the cultural economic perspective
Authors: Handke Christian , Dalla Chiesa Carolina 
Published: February 2022

AbstractCrowdfunding is an innovation from the cultural sector that has found broad applications in other aspects of the economy. We document that cultural economics provides a refined structure to explain much of the crowdfunding phenomenon, which will be useful for any research on this topic. Based on central themes of cultural economics (including quality and demand uncertainty, socially interdependent demand formation, public good attributes, and intrinsic motivation to create), we extend on the current understanding in the crowdfunding literature regarding three fundamental questions: (1) under what circumstances is crowdfunding a superior alternative to traded means of financing innovative projects? (2) What types of crowdfunding are best suited for specific (cultural and creative) industries (CCI)? (3) What is the potential of crowdfunding for cultural and creative industries? Overall, we describe crowdfunding as a flexible tool for mitigating various, fundamental challenges in CCI and beyond. We also identify limitations of crowdfunding, which for now, severely restrict its application. Arguably, the main boon of crowdfunding for cultural economics is not so much that it makes markets (for cultural products) much more efficient and fosters growth. Instead, crowdfunding enables sophisticated empirical research on central topics of cultural economics, and a rich and diverse literature has begun lifting that treasure.

AbstractFor transformers and inductors to meet the world’s growing demand for electrical power, more efficient soft magnetic materials with high saturation magnetic polarization and high electrical resistivity are needed. This work aimed at the development of a soft magnetic composite synthesized via spark plasma sintering with both high saturation magnetic polarization and high electrical resistivity for efficient soft magnetic cores. CoFe powder particles coated with an insulating layer of Al2O3 were used as feedstock material to improve the electrical resistivity while retaining high saturation magnetic polarization. By maintaining a continuous non-magnetic Al2O3 phase throughout the material, both a high saturation magnetic polarization, above 1.5 T, and high electrical resistivity, above 100 μΩ·m, were achieved. Through microstructural characterization of samples consolidated at various temperatures, the role of microstructural evolution on the magnetic and electronic properties of the composite was elucidated. Upon consolidation at relatively high temperature, the CoFe was to found plastically deform and flow into the Al2O3 phase at the particle boundaries and this phenomenon was attributed to low resistivity in the composite. In contrast, at lower consolidation temperatures, perforation of the Al2O3 phase was not observed and a high electrical resistivity was achieved, while maintaining a high magnetic polarization, ideal for more efficient soft magnetic materials for transformers and inductors.

AbstractThere are eight famous thermal water sources, with medium temperature, neutral pH, high ranges of TDS values located in different carbonate formations in Northern Vietnam. The chemical composition results showed the major elements present were Na, K, Mg, Ca, Sr, while trace amounts of rare earth elements (REE), Ag, As, Pb, Th, U were observed. The 210Po activity concentration and the annual committed effective doses for adults, children, and infants in all study areas were far less than 100 mBq L−1 and 0.1 mSv y−1, respectively. Some significant correlations between 210Po and other chemical components have been observed.

Authors: Kaltenbacher Barbara 
Published: February 2022

AbstractThe aim of this paper is to put the problem of vibroacoustic imaging into the mathematical framework of inverse problems (more precisely, coefficient identification in PDEs) and regularization. We present a model in frequency domain, prove uniqueness of recovery of the spatially varying nonlinearity parameter from measurements of the acoustic pressure at multiple frequencies, and derive Newton as well as gradient based reconstruction methods.
Homogeneity and trend analysis of rainfall and droughts over Southeast Australia
Authors: Yildirim Gokhan , Rahman Ataur 
Published: February 2022

AbstractThis study investigates rainfall and drought characteristics in southeastern Australia (New South Wales and Victoria) using data from 45 rainfall stations. Four homogeneity tests are adopted to determine inhomogeneities in the annual total rainfall (ATR) and monthly rainfall data, namely The Pettitt test, the SNHT, the Buishand range test and the Von Neumann ratio test at significance levels of 1%, 5%, and 10%. Temporal trends in rainfall (ATR, monthly, and seasonal) and droughts are examined using autocorrelated Mann–Kendall (A-MK) trend test at 1%, 5%, and 10% significance levels. We also assess meteorological droughts by using multiple drought indices (3-, 6-, 9-, 12-, 24-, and 36-month Standardized Precipitation Index (SPI) and Effective Drought Index (EDI)). Furthermore, spatial variability of temporal trends in rainfall and drought are investigated through interpolation of Sen’s slope estimator. The results represent an increasing trend in ATR between 1920 and 2019. However, southeast Australia is highly dominated by a significant negative trend in the medium term between 1970 and 2019. Winter is found to be dominated by a significantly negative trend, whereas summer and spring seasons are dominated by a positive trend. April is detected as the driest month according to magnitude of Sen’s slope and the A-MK test result. Positive trends on droughts are observed at inner parts of the study area, whereas a negative trend is detected in the south, southeast, and northeast of the study area based on SPIs and EDI. The findings of this study help to understand changes in rainfall and droughts in southeastern Australia.
Covid-19 and Capital Flows: The Responses of Investors to the Responses of Governments
Authors: Goldbach Stefan , Nitsch Volker 
Published: February 2022

AbstractThis paper examines the effect of national government response measures to Covid-19 on German international capital flows. Analyzing highly disaggregated monthly data from the German balance of payments statistics over the period from January 2019 through January 2021, we find that bilateral financial interactions are negatively affected by stricter containment and closure policies as well as health system policies of a partner country, while German capital flows benefit from a partner’s economic support policies. Moreover, to the extent that public interventions to fight the pandemic affect financial interactions, the adjustment mainly takes place along the intensive margin.
Debiasing or regularisation? Two interpretations of the concept of ‘true preference’ in behavioural economics
Authors: Sugden Robert 
Published: February 2022

AbstractI reconsider Bleichrodt, Pinto Prades and Wakker’s (BPW) 2001 paper about eliciting utility measures from stated preference surveys. That paper pioneers a method that is now widely used in behavioural economics to correct individuals’ ‘biases’ and to recover their ‘true preferences’. However, BPW propose this method as way of dealing with inconsistent responses to stated preference surveys, in contrast to more recent applications which aim to help individuals to avoid supposed mistakes in their private choices. I argue that the concepts of true preference and bias are empirically ungrounded, but that BPW’s approach can be interpreted as not invoking those concepts. By ‘regularising’ preferences revealed in actual choice, this approach constructs measures of individual welfare that are broadly aligned with actual preferences and consistent with normative standards of rationality that are appropriate for public decision-making. Public decision-makers’ normative judgements are made explicit, rather than being disguised as apparently empirical claims about true preferences.

AbstractDuring the Deepwater Horizon (DwH) oil spill, an excessive production of marine snow was observed, and it was estimated that as much as 14% of the oil was transferred to the ocean floor by MOSSFA (Marine Oil Snow Sedimentation and Flocculent Accumulation). MOSSFA is an important pathway of transferring oil to the ocean floor. We performed experiments at laboratory scale in 15 aquaria, representing 5 exposures of marine snow with or without oil, only oil, and controls with only clay or sediment. We developed a method to produce artificial marine snow, which resembles the natural marine snow. Results showed 40% less biodegradation of alkanes in “marine snow with oil” compared to “only oil.” Most probably, this is due to preferred biodegradation of marine snow organics comparing to oil alkanes. Biodegradation of marine snow reduces the dissolved oxygen concentration, which might result in anaerobic conditions in the sediment layer. This finding can be projected to a potential ocean floor effect.
Black girls matter: A critical analysis of educational spaces and call for community-based programs
Authors: King Natalie S. 
Published: February 2022

AbstractThis forum paper dialogues with Crystal Morton and Demetrice Smith-Mutegi’s Making “it” matter: Developing African American girls and young women’s mathematics and science identities through informal STEM learning. Their article unveils the experiences of participants in Girls STEM Institute, and how they challenged beliefs about their ability to perform in science and mathematics. I extend the discussion to explore the importance of access through community-based initiatives and stand on the premise that we will continue to oxygenate master narratives and perpetuate inequities if the structure and function of our programs fail to challenge the status quo. Therefore, this paper serves as a call to action to (1) recognize and address spirit murdering from teachers and authority figures who dismiss the abilities of Black girls to perform in STEM; (2) create humanizing spaces within schools and the larger community for Black girls to access STEM with authenticity; and (3) leverage the multidimensional identities of Black girls in ways that validate their cultural resources and brilliance. When we commit ourselves to creating more equitable learning spaces in STEM, then our actions will align with our responsibility to make Black girls matter.

Abstract
Purpose
Excellent metabolic improvement following one anastomosis gastric bypass (OAGB) remains compromised by the risk of esophageal bile reflux and theoretical carcinogenic potential. No ‘gold standard’ investigation exists for esophageal bile reflux, with diverse methods employed in the few studies evaluating it post-obesity surgery. As such, data on the incidence and severity of esophageal bile reflux is limited, with comparative studies lacking. This study aims to use specifically tailored biliary scintigraphy and upper gastrointestinal endoscopy protocols to evaluate esophageal bile reflux after OAGB, sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB).

Methods
Fifty-eight participants underwent OAGB (20), SG (15) or RYGB (23) between November 2018 and July 2020. Pre-operative reflux symptom assessment and gastroscopy were performed and repeated post-operatively at 6 months along with biliary scintigraphy.

Results
Gastric reflux of bile was identified by biliary scintigraphy in 14 OAGB (70%), one RYGB (5%) and four SG participants (31%), with a mean of 2.9% (SD 1.5) reflux (% of total radioactivity). One participant (OAGB) demonstrated esophageal bile reflux. De novo macro- or microscopic gastroesophagitis occurred in 11 OAGB (58%), 8 SG (57%) and 7 RYGB (30%) participants. Thirteen participants had worsened reflux symptoms post-operatively (OAGB, 4; SG, 7; RYGB, 2). Scintigraphic esophageal bile reflux bore no statistical association with de novo gastroesophagitis or reflux symptoms.

Conclusion
Despite high incidence of gastric bile reflux post-OAGB, esophageal bile reflux is rare. With scarce literature of tumour development post-OAGB, frequent low-volume gastric bile reflux likely bears little clinical consequence; however, longer-term studies are needed.

AbstractRobot-assisted radical prostatectomy (RARP) is the most adopted treatment for localized prostate cancer. The aim of this study was to explore the learning curves (LC) for overall and site-specific positive surgical margins (PSM) occurrence after RARP of multiple surgeons within a step-structured mentor-initiated training program. The study included consecutive patients undergoing RARP between January 2013 and March 2020, by three surgeons: a mentor and his two trainees. Prospectively collected patients’ data were retrospectively analyzed. The cumulative summation (CUSUM) method was used to generate the LCs, with turning points indicating the number of cases to reach proficiency levels. Furthermore, the association between PSM and surgical experience was evaluated, adjusting for case mix. A total of 761 consecutive patients were included, 370 treated by the Mentor surgeon, 247 and 144 treated, respectively, by the two Trainees. Mentor and Trainees had similar PSM rates (31.6% vs 28.0% vs 31.3%, p = 0.6). CUSUM charts showed different LC shapes for different PSM locations (postero-lateral, bladder neck, apex, and multifocal/> 3 mm). Surgical experience was significantly associated with overall, postero-lateral, and multifocal/> 3 mm PSMs, in the Mentor series only. Trainees reached their turning points after far fewer cases then the Mentor, both for overall (12 and 31 vs 153), postero-lateral (24 and 30 vs 120), and multifocal/> 3 mm PSMs (9 and 31 vs 153). The achievement of stable SM proficiency takes involved different LCs depending on the prostatic location being considered. Monitoring site-specific LC can indicate the surgical steps for which there may be still room for further technical refinements, even when an apparent proficiency status seems achieved.
Research progress and prospects of complete ammonia oxidizing bacteria in wastewater treatment
Authors: Luo Shaoping , Peng Yi , Liu Ying , Peng Yongzhen 
Published: February 2022

AbstractComplete ammonia oxidizing bacteria, or comammox bacteria (CAOB), can oxidize ammonium to nitrate on its own. Its discovery revolutionized our understanding of biological nitrification, and its distribution in both natural and artificial systems has enabled a reevaluation of the relative contribution of microorganisms to the nitrogen cycle. Its wide distribution, adaptation to oligotrophic medium, and diverse metabolic pathways, means extensive research on CAOB and its application in water treatment can be promoted. Furthermore, the energy-saving characteristics of high oxygen affinity and low sludge production may also become frontier directions for wastewater treatment. This paper provides an overview of the discovery and environmental distribution of CAOB, as well as the physiological characteristics of the microorganisms, such as nutrient medium, environmental factors, enzymes, and metabolism, focusing on future research and the application of CAOB in wastewater treatment. Further research should be carried out on the physiological characteristics of CAOB, to analyze its ecological niche and impact factors, and explore its application potential in wastewater treatment nitrogen cycle improvement.
A Mixed-methods Exploration of Young Adults’ Views of the Sexual Double Standard
Authors: Wesson Charlotte 
Published: February 2022

AbstractThe traditional sexual double standard occurs when men and women are evaluated differently for the same sexual behaviours. Typically, women are judged more punitively than their male counterparts regarding promiscuous behaviour. There is much research surrounding this double standard. However, there has been less investigation into what factors individuals consider responsible for this phenomenon. The present study aimed to use qualitative and quantitative methods to examine young adults’ attitudes to this double standard. Three main themes were observed and are discussed across this article. These themes include, Theme (1) Attitudes from the past, Theme (2) (Un)acceptability of behaviour and Theme (3) Media portrayal.
Psychophysiological stress response in SCUBA divers: The contribution of negative automatic thoughts and negative emotions

Published: February 2022

AbstractThe research questions in this study were to examine the contribution of negative automatic thoughts and negative emotions, measured by two newly-constructed questionnaires, to psychophysiological stress responses among more experienced military and less experienced recreational divers. Further, we examined whether daily variations in cortisol levels could be attributed to the impact of negative thoughts/emotions rather than diving experience. Altogether 15 recreational and 14 military male divers participated in the dive wherein stress responses were measured by anxiety measures (DASS-21 and STAI) and cortisol salivary concentrations. The results of factor analysis and principal component analysis demonstrated acceptable construct validity and internal consistency of both questionanires. Recreational and military divers did not differ significantly in the proportion of negative thoughts and emotions, while recreational divers had significantly higher levels of cortisol release after awakening and immediately before/after diving, indicating their more intense stress responses. A significant interaction between daily variations in cortisol secretion and negative emotions indicated a greater importance of emotions in response to diving stress rather than diving experience. Accordingly, using a multiple regression analysis showed that more pre-diving negative emotions predicted higher levels of pre-diving anxiety and depression as well as more cortisol release. More negative thoughts predicted higher levels of depressive symptoms, while belonging to a group of recreational divers was a significant predictor of higher pre-diving anxiety. This study points to the importance of considering cognitive and emotional experiences, particularly in recreational divers, for the purpose of prevention of negative psychophysiological stress responses prior to diving.
How humor is experienced: An embodied metaphor account
Authors: Xu Tingting , Liu Meichun , Wang Xiaolu 
Published: February 2022

AbstractThe study explores the humor-body association from the perspective of embodied cognition. According to the Conceptual Metaphor Theory, abstract concepts tend to be understood with concrete experiences through embodied mappings. Therefore, the current study attempts to investigate how humor, an understudied abstract concept, is perceived in the Chinese context by means of textual analysis and a behavioral experiment. Firstly, 6,500 entries of the corpus data related to laughter and humor in Chinese were used for the textual analysis. Extensive uses of embodied humor metaphors were found, which provided important linguistic evidence for the interaction between laughter, humor, and body. Secondly, a behavioral study was conducted based on some frequently-used embodied metaphorical expressions of humor (e.g.,pěngfù dàxiào捧腹大笑, meaning ‘to hold one’s sides laughing’) identified in the corpus. Specifically, the participants were instructed to either do embodied metaphor or non-metaphor actions as bodily primes (i.e., ‘holding one’s belly while bending forward and backward repeatedly’ vs. ‘turning one’s upper body from side to side with both hands on the back’) or perform no actions before completing the subsequent joke rating task and the mood rating task. Results showed that the participants who were primed with the embodied metaphor actions rated the jokes higher than those in the control groups who were primed with non-metaphor actions or had no primes. Also, there was no significant difference in the mood ratings across the groups. These findings suggest that embodied humor metaphors indeed affect humor experience and shape how humor is conceptualized. The current study supports not only the embodied view of humor understanding but also the conceptual metaphor account of abstract reasoning, which sheds new light on the theoretical development of the embodiment of abstract concepts.
Data-Augmentation Method for BERT-based Legal Textual Entailment Systems in COLIEE Statute Law Task

Published: February 2022

AbstractA legal textual entailment task is a task to recognize entailment between a law article and its statements. In the Competition on Legal Information Extraction/Entailment (COLIEE), this task is designed as a task to confirm the entailment of a yes/no answer from the given civil code article(s). Based on the development of deep-learning-based natural language processing tools such as bidirectional encoder representations from transformers (BERT), many participants in the task used such tools, and the best performance system of COLIEE 2020 was a BERT-based system. However, because of the limitation of the size of training data provided by the task organizer, training such tools to adapt to the variability of the questions is difficult. In this paper, we propose a data-augmentation method to make training data using civil code articles for understanding the syntactic structure of the questions and articles for entailment. Our BERT-based ensemble system, which uses this augmentation method, achieves the best performance (accuracy = 0.7037) in Task 4 of COLIEE 2021. We also introduce the results of additional experiments to discuss the characteristics of the proposed method.
