The price effects of reducing payment card interchange fees
Authors: Shabgard Bita , Asensio Javier 
Published: April 2023

AbstractIn this paper we empirically address the issue of whether reductions in card payment interchange fees have a significant impact on prices paid by consumers. The answer to this question is at the core of most competition policy cases and regulations that have been applied to card payment markets. Relying on Rochet and Tirole’s (RandJEcon 33:549–570, 2002) model of this sector as a two-sided market, we identify the two channels through which interchange fee reductions may influence retail prices: the impact on cards’ demand and on the merchant service charge, which may be passed through to retail prices. We use Spanish sectoral data to estimate the resulting system of equations. Our results imply that a 1% reduction in the level of the interchange fee leads to a long run 0.17% reduction in the retail price index. Such outcome is almost exclusively the result of the interchange fees being passed through as lower prices by merchants, as we find that they have a negligible impact on payment cards’ usage.

AbstractWater security is the central mission of the sustainable development goals. The demand for potable and clean water has skyrocketed due to frequent borehole failures and population expansion, which requires adequate groundwater resource management strategies. Identifying groundwater potential zone, overburden protective index capacity and installations of alternative/artificial storage support mechanisms for water security and sustainability under the growing water challenge and demand is critical. This study identifies; (i) aquifer promising zones (ii) aquifer protective capacity through geophysical investigation and suggests (iii) improving aquifer recovery management strategy as the top three targets for groundwater development. An electric resistivity technique was applied to acquire a total of sixty (60) vertical electrical sounding points with Schlumberger arrays. The study indicates the resistivity layer of the aquifer unit ranges from 21 to 294 Ωm, while the aquifer layer thickness values spread from 8 to 59 m and the overburden thickness overlays the aquifer unit extends from 3 to 20 m. The deeper aquifer zones were encountered between 30 and 59 m, which could be suitable for groundwater development, and the shallow aquifer occurs between 8 and 14 m, which is not encouraging for groundwater development and may be susceptible to surface contaminations. However, for water security and sustainability, multiple boreholes should be sited at the delineated aquifer promising zone where the aquifer is fractured and occurs within a depth of 30 m and above. The weathered/fractured units constitute the regional aquifer units, which are largely responsible for the groundwater potential. The hydraulic conductivity of the regional aquifer was estimated to vary between 0.337 and 10.62 m/day, which invariably enhances the aquifer recovery processing. Groundwater quality and the risk of surface contamination were examined through overburden protective index capacity.

AbstractTo improve the phosphorus (P) recovery efficiency from livestock wastewater, a novel MgO doped mildewed corn biochar with thermal pre-puffing treatment (Mg-PBC) and without pre-puffing (Mg-BC) was synthesized and tested. The thermal-puffing pretreatment improved the effectiveness of metal soaking and MgO dispersion. P recovery time with Mg-PBC (7 h) was significantly shorter than that with Mg-BC (12 h). Moreover, Mg-PBC showed significantly higher P recovery capacity (241 mg g−1) than Mg-BC (96.6 mg g−1). P recovery capacity of the Mg-PBC fitted to the Thomas model was 90.7 mg g−1, which was 4 times higher than that of Mg-BC (22.9 mg g−1) under column test conditions. The mechanisms involved in P recovery included precipitation, surface complexation, and electrostatic interaction. After adsorption, both Mg-BC and Mg-PBC showed relatively low regeneration abilities. The P loaded Mg-BC (Mg-BC-P) and Mg-PBC (Mg-PBC-P), the later particularly, obviously increased the available P content and promoted plant growth. The release of P increased with time in the Mg-PBC-P treated soil, while it decreased with time in the P fertilizer treated soil. A cost–benefit analysis revealed that thermal-puffing pretreatment greatly increased the profit of MgO doped biochar from −0.66 to 5.90 US$ kg−1. These findings highlight that biomass pre-puffing is a feasible treatment to produce MgO modified biochar and to recover P from livestock wastewater, and that the Mg-PBC-P can be used as a slow-release P fertilizer.

Published: April 2023

AbstractThe High Line park (HLP) in New York City is one of the most successful contemporary greenway parks, inspiring urban planners, designers, artists, and administrators worldwide. This study provides a comprehensive understanding of user experiences in a long-term time frame (2011–2018) through the lens of online reviews. Using a mixed-methods approach, we conducted Latent Dirichlet Allocation (LDA) topic modeling to quantitatively identify the key topics that represent 34,060 reviews and 30,285 users, followed by qualitative analysis to inductively interpret the LDA topics. The results identified experiential, programmatic and physical elements of the HLP that are meaningful to users. Three primary components were found that make HLP successful according to users: spectacular visual and activity-related experiences, the historical transformation and cultural exploration, and the added value from park services ranging from amenities to on-site living performance. The article helps inform future decision-making and planning & design practices for future greenway projects.
Solubility of Na2O·xAl2O3 in NaF-KF-AlF3-based low-temperature electrolyte
Authors: Kuang Ye , Yan Hengwei , Liu Zhanwei , Yang Yonghui 
Published: April 2023

AbstractThe solubility of Na2O·xAl2O3 in a NaF-KF-AlF3-based low-temperature electrolyte was investigated, and the influence of electrolyte temperature at 750 ℃, CR = 1.3–1.4, CaF2, and LiF on the alumina solubility was studied. The dissolution rate of alumina in the electrolyte was determined by measuring the alumina concentration in the electrolyte at different times with an oxygen analyzer. The results showed that in the NaF-KF-AlF3-based low-temperature electrolyte, the dissolution rate of alumina in Na2O·xAl2O3 was faster than that of Al2O3. As the Na2O content in alumina increased, the dissolution rate increased. Similarly, a higher CR of NaF-KF-AlF3 and a higher temperature of the molten salt (750–850 °C) increased the dissolution rate of alumina in the electrolyte. The dissolution rate of alumina in NaF-KF-AlF3 decreased after adding CaF2 and LiF. According to the kinetics analysis, the dissolution rate of alumina followed the zero-order reaction rate law from 0–5 min, which showed that it depended on the amount of alumina absorbed in the electrolyte in the first five minutes.
Charting AI urbanism: conceptual sources and spatial implications of urban artificial intelligence
Authors: Palmini Otello , Cugurullo Federico 
Published: April 2023

AbstractThe aim of this paper is to tease out some of the key issues concerning the relationship between AI and urbanism. This relationship, which is presented in the academic literature as a new driving force of contemporary urbanism, will be investigated through an interdisciplinary approach that places urban studies and philosophy of technology in dialogue. Thus, the analysis will not focus on the technological development of artificial intelligence systems but on how their application can affect urbanistic thinking and vice versa. The chart that is produced by this method is based on two fundamental axes: time and space. AI urbanism will then be inquired first through key turning points in the history of the relationship between technology and the city (modern urbanism, cybernetics and the smart city paradigm). Secondly, the spatial implications of urban AI will be investigated from the point of view of the concrete applications of this technology to the city (Robots, AVs, Software agents) and their impact on the relationships between different urban actors. Ultimately, this work aims to offer a conceptual tool for understanding some decisive implications of the relationship between AI and urbanism, such as the connection between quantitative and qualitative approaches, the implications related to autonomous technology, the economic-political background of AI urbanism, the material urban impact of AI, and the relationship between AI and other urban intelligences. Understanding these implications will be valuable for future research on AI urbanism oriented toward transforming simple technological development into sustainable urban innovations.

Published: April 2023

AbstractThe demand for multi-point water quality monitoring is increasing to solve the global problem of safe drinking water supply and environmental water contamination by industries. Therefore, compact devices are needed for on-site water quality analysis. On-site devices require low cost and high durability because they are placed outdoors, exposing them to strong ultraviolet rays and a wide range of temperatures. Our previous study reported on a compact and low-cost water quality meter that uses microfluidic devices with resin to monitor chemicals. In this study, we extended the fabrication range of the glass molding method to fabricate a glass microfluidic device with a 300 µm deep channel on a 50 mm in diameter substrate for constructing a low-cost and high-durability device. Finally, we developed a low-cost, highly robust glass device with a diamond-like carbon-coated channel surface to measure residual chlorine. The experimental results indicated that this device can endure outdoor conditions and be attached to small internet of things devices for analyzing chemical substances, such as residual chlorine.

On Becoming in Sync with Yourself and Others: An Adaptive Agent Model for How Persons Connect by Detecting Intrapersonal and Interpersonal Synchrony

Published: April 2023

AbstractResearch indicates that interpersonal synchronisation leads to more closeness, mutual coordination, alliance, or affiliation between the synchronized persons. There is a pathway leading from interpersonal interaction to interpersonal synchronisation, and then to interpersonal affiliation. If persons act on temporal patterns of synchrony, this suggests that they possess a facility to detect such patterns. Therefore, we assume here that persons indeed detect when temporal patterns of synchrony occur and that a stronger affiliation or connection may grow from this detection. We developed a multi-adaptive agent model that contains detector states for both intrapersonal and interpersonal synchrony, which in turn dynamically affect interpersonal affiliation. We evaluated the behaviour of two agents in multiple simulation experiments in which stochastic stimuli were manipulated. Several expected types of patterns were reproduced computationally, and our multi-adaptive agent model may serve as base for the development of virtual agents that can synchronise with their users. By multiple simulation experiments for stochastic stimuli from the environment, it was found that indeed several expected types of patterns are reproduced computationally.
Sustainability of the plastron on nano-grass-covered micro-trench superhydrophobic surfaces in high-speed flows of open water

Published: April 2023

This paper studies the sustainability of plastrons on superhydrophobic (SHPo) surfaces made of longitudinal micro-trenches covered by nano-grass with the main interest on hydrodynamic friction drag reduction in high-speed flows of open water, which represent the operating conditions of common watercraft. After revising the shear-driven drainage model to address the air diffusion for SHPo surfaces, the existing theories are combined to reveal the trends of how the immersion depth, air saturation level and shear stress affect the maximum attainable plastron length. Deviations from the theories by the dynamic effect at the two ends of the trench, the interfacial contaminations and turbulent fluctuation are also discussed. A combinatorial series of well-defined SHPo trench surfaces (4 cm × 7 cm in size with varying trench widths, depths, lengths and roughnesses) is microfabricated and attached underneath a 4 m long motorboat on seawater in turbulent flows up to 7.2 m s−1(shear rate ∼83 000 s−1and friction Reynolds number ∼5500). Because the plastron can provide a substantial slip only while its air–water interfaces are pinned (or only slightly depinned) at the trench top, two underwater cameras are employed to differentiate the pinned (and slightly depinned) interfaces from the depinned (and no) interfaces. In addition to achieving pinned plastrons on 6 cm long trenches aligned to high-speed flows in open water, the experimental results corroborate the theoretical estimations, supporting the design of SHPo surfaces for field applications.
Corporate Political Ties and Firm Performance in a Transition Economy: A Replication and Extension of Peng and Luo (2000)

Published: April 2023

ABSTRACTHow do corporate political ties impact firm performance in a transition economy? This topic has attracted wide attention in the strategy field. Accordingly, our study replicates a highly influential study, ‘Managerial ties and firm performance in a transition economy: The nature of a micro-macro link’ (Peng & Luo, 2000). The original study found that managerial political ties greatly improve organizational performance, and that this ‘micro-macro’ link varies across ownership types, business sectors, firm sizes, and industry growth rates. This replication study offers a hierarchical view of political ties by extending it from the individual to the organizational level and explores the complex link between the two levels of corporate political ties and firm performance. The results of a staged quasi-replication exercise show some similarities with the original study in the mechanism of corporate political ties on firm performance but, more importantly, reveal some key differences in the effect size and contingent effects. Furthermore, an extended test shows that corporate political ties are multilevel, and different levels of political ties vary in their mechanisms and effects on firm performance. The findings reveal temporal and contextual sensitivities of political ties studies in transition economies.

AbstractWe describe the design, validation, and commissioning of a new correlator termed ‘MWAX’ for the Murchison Widefield Array (MWA) low-frequency radio telescope. MWAX replaces an earlier generation MWA correlator, extending correlation capabilities and providing greater flexibility, scalability, and maintainability. MWAX is designed to exploit current and future Phase II/III upgrades to MWA infrastructure, most notably the simultaneous correlation of all 256 of the MWA’s antenna tiles (and potentially more in future). MWAX is a fully software-programmable correlator based around an ethernet multicast architecture. At its core is a cluster of 24 high-performance GPU-enabled commercial-off-the-shelf compute servers that together process in real-time up to 24 coarse channels of 1.28 MHz bandwidth each. The system is highly flexible and scalable in terms of the number of antenna tiles and number of coarse channels to be correlated, and it offers a wide range of frequency/time resolution combinations to users. We conclude with a roadmap of future enhancements and extensions that we anticipate will be progressively rolled out over time.
Challenges in Applying Colonial Boundary Treaties to the Resolution of the Djibouti–Eritrea Border Dispute

Published: April 2023

AbstractDjibouti and Eritrea have been in conflict since June 2008 when their troops fought along the Djibouti–Eritrea border. The conflict revolves around the location of the border and sovereignty over the strategically located Doumeira Islands and adjacent reefs. In 2010 Qatar brokered a mediation agreement and began to implement it, but withdrew in 2017 without notifying Eritrea and without providing reasons to either country. The dispute raises a number of international law issues. This article focuses on the validity and application of three relevant colonial treaties (from 1900, 1901 and 1935) that defined the boundary, one of which (the 1935 Treaty) did not enter into force. Issues relevant to the determination of the borderline and sovereignty over the disputed islands and the unique challenges that may arise are discussed in light of the colonial treaties, relevant International Court of Justice jurisprudence and other international law principles, particularly uti possidetis juris.
Effects of Zeowine and compost on leaf functionality and berry composition in Sangiovese grapevines

Published: April 2023

AbstractMeteorological extremes such as heatwaves and water limitations during the ripening season could negatively impact vine ecophysiology and berry metabolism resulting in lower yield per vine. This project aimed to compare two different soil managements during two growing-production seasons (2021 and 2022) with respect to control without any treatment (control). The two managements were: Zeowine (30 t/ha; a soil conditioner made with clinoptilolite and compost proceeding of industrial wine-waste) and compost (20 t/ha). The trial was organized at Col d'Orcia Estate (Montalcino, Tuscan wine region, Italy). The purpose was twofold: (1) to evaluate the effects of Zeowine treatments on leaf gas exchanges, midday stem water potential, chlorophyll fluorescence and leaf temperature (ecophysiology); and (2) to determine any repercussions on the quality of the grapes (technological and phenolics analyses). The parameters plant yield, yeast assimilable nitrogen, fractionation of anthocyanins (cyanidin, delphinidin, malvidin, peonidin and petunidin), caffeic acid, coumaric acid, gallic acid, ferulic acid, kaempferol and quercetin were also analysed. Zeowine showed higher photosynthesis, less negative midday water potential and lower leaf temperature. Essentially, no significant difference was found between the compost and the control. Furthermore, Zeowine grapevines showed higher anthocyanin accumulation and less quercetin content. In general, compost applied together with zeolite could alleviate the adverse effects of water stress and improve plant growth, yield and quality. The control management strategy proved to be the least beneficial for the well-being of the plant and the final quality of the product, confirming the need for amendments in critical years.
Identity, ethics and behavioural welfare economics

Published: April 2023

AbstractMultiple selves is a conventional assumption in behavioural welfare economics for modelling intrapersonal well-being. Yet an important question is which self has normative authority over others. In this paper, we advance an argument for what we call the ‘ontological approach’ to personal identity in behavioural welfare economics. According to this approach, ethical questions – such as which preference should be granted normative authority over another – can be informed by the ontological criterion of personal persistence, which aims at determining what it takes for an individual to persist from one time to another.

AbstractSudden cardiac death is the most common mode of death during childhood and adolescence in hypertrophic cardiomyopathy, and identifying those individuals at highest risk is a major aspect of clinical care. The mainstay of preventative therapy is the implantable cardioverter-defibrillator, which has been shown to be effective at terminating malignant ventricular arrhythmias in children with hypertrophic cardiomyopathy but can be associated with substantial morbidity. Accurate identification of those children at highest risk who would benefit most from implantable cardioverter-defibrillator implantation while minimising the risk of complications is, therefore, essential. This position statement, on behalf of the Association for European Paediatric and Congenital Cardiology (AEPC), reviews the currently available data on established and proposed risk factors for sudden cardiac death in childhood-onset hypertrophic cardiomyopathy and current approaches for risk stratification in this population. It also provides guidance on identification of individuals at risk of sudden cardiac death and optimal management of implantable cardioverter-defibrillators in children and adolescents with hypertrophic cardiomyopathy.
Forgotten Pasts and Imagined Futures: The First International Webern Festival and the 1962 Seattle World's Fair
Authors: MILLER DAVID H. 
Published: April 2023

AbstractIn an April 1962 article previewing the First International Webern Festival, Hans Moldenhauer promised that Anton Webern's music would one day be known as ‘the music of the space age’. Moldenhauer chose his words carefully. The Webern Festival was set to take place in Seattle at the same time as the World's Fair (an event also known as the ‘Century 21 Exposition’ and ‘America's Space Age World's Fair’) and its opening night concert would be held on the grounds of the World's Fair. Yet the two ‘W.F.s’ made for an awkward pairing. Far from space-age music, the lush textures and sweeping gestures of the Webern's Festival's posthumous premieres revealed a young Webern rooted in nineteenth-century Romanticism. Critics and scholars’ responses to these premieres reveal much about the contested place of Webern's music – and modernist music more generally – within mid-century mainstream culture.
