Using nonradial metafrontier data envelopment analysis to evaluate the metatechnology and metafactor ratios for the Taiwanese hotel industry
Authors: Huang Chin‐wei , Chen Hsiao‐Yin 
Published: December 2022

AbstractThe main purpose of this study was to develop nonradial metafrontier data envelopment analysis (DEA). Previous studies commonly used assumptions involving the redial measure and convexity of metafrontier to evaluate efficiency and the technology gap. The two assumptions have limitations, and a model that modifies the two assumptions simultaneously has not been proposed. In this study, a nonradial metafrontier DEA is proposed that incorporates the assumptions of nonconvexity as well as the nonradial measure. The study also developed the MFR index for measuring the technology gap based on individual factors.
Vertical integration to avoid monopsonistic exploitation
Authors: Alderman Brianna L. , Blair Roger D. 
Published: December 2022

AbstractFor decades, the suppliers of fed cattle have complained about monopsonistic exploitation by the dominant meatpackers. Recently, a group of ranchers and feedlot operators joined forces to build their own meatpacking plant in an effort to avoid such exploitation. In this context, we show that forward vertical integration by the suppliers of fed cattle will increase their profits while increasing output and lowering prices for consumers. In addition, we show that vertical integration improves both consumer welfare and social welfare. We also examine the use of a joint sales agency, which is an economically equivalent alternative to vertical integration.
Window of opportunity: screening for GCK monogenic diabetes in the antenatal diabetes clinic
Authors: Surendran Aarthi , Brackenridge Anna , White Sara L 
Published: December 2022

Abstract
Monogenic diabetes (MODY) is a rare, inherited form of diabetes, of which glucokinase (GCK) mutation is one of the most common forms. Correct diagnosis is important, particularly during pregnancy, as treatment should be tailored accordingly. In our antenatal diabetes clinic, we audited those eligible for genetic screening over a one‐year period as per European Best Practice guidelines (2008) and new NHS England criteria (2021), as well as those identified with the mutation. Our audit recorded a significant drop in the number of eligible women identified using new criteria (2.6% vs 5.2%), with a notable reduction in women of African ethnicity (15.2% vs 29.2%). The audit highlighted the need for increased health care professional awareness and the implementation of clear pathways within the antenatal diabetes service to facilitate identification of women for genetic screening and subsequent appropriate management. It also underlined the importance of ongoing assessment of the clinical performance of the new screening criteria. Copyright © 2022 John Wiley & Sons.
Sociotechnical interdependencies and tipping‐point dynamics in data‐intensive services
Authors: Ghaffarzadegan Navid , Mostafavi Sarah , Kim Hyunjung 
Published: December 2022

AbstractService science theories do not fully explain failure cases in data‐intensive services – high‐technology services that utilize large volumes of data and provide customized information for users. In these service systems, the technological and social elements are highly interconnected: firms cannot maintain databases and analytic capabilities if they lack market penetration, which itself is influenced by performance of analytic capabilities and databases; a positive feedback loop. Informed by a case study, we develop a simulation model, postulate that market adoption is highly sensitive to the launch conditions, specifically with respect to the initial states of the system, and offer a dynamic theory in which highly nonlinear relationships among the initial states of the system drive outcomes of the market adoption of data‐intensive services. We argue that a tipping point exists at which small technological differences in the launch period differentiates between market success and failure. Furthermore, our analysis points to a strong self‐fulfilling mechanism whereby initial positive customer perception can increase the service's likelihood of success by indirectly influencing technological improvement. In contrast to the conventional belief, having a large number of initial adopters may negatively influence market adoption in the long run. A major source of the patterns observed is the high level of interdependencies between social and technological elements of data‐intensive services. © 2022 System Dynamics Society.
Hybrid rubber‐concrete isolation slab system with various shape factors for structures subjected to horizontal and vertical vibrations
Authors: Fayyadh Nahal Kamil , Hejazi Farzad 
Published: December 2022

SummaryThe present framework proposed the development of a Hybrid Rubber‐Concrete Isolation Slab System (HRCISS) to support building structures subjected to horizontal and vertical vibration due to ground motion and machine or equipment operation in the structure. Given that the effect of the shape factor on both horizontal and vertical stiffness has yet to be reported, the proposed composite system was comprised of two layers under the nodal points of the upper layer near the slab corners with four High Damping Rubber (HDR) components positioned between the slab layers to dissipate multidirectional (horizontal and vertical directions) vibrations. The ABAQUS software was utilized to model the finite element model (FEM) and simulate the HRCISS subjected to cyclic horizontal and vertical displacements. For the optimal HDR design, the model was applied in five 3‐story buildings, and the effect of distinct shape factors (0
S
2) of the HDR bearings—the ratio of bearing's loaded area to unloaded area (free to bulge)—within the hybrid system was evaluated. For each building with a specific HDR shape factor, the HRCISS was installed in the first, second, and third stories, separately, to investigate the influence of the installation level of the isolation system on the overall structural performance. The multistory buildings were subjected to two types of vibration loads: the interior machine‐induced vibrations, and the exterior seismic‐induced vibrations in the horizontal and vertical directions. Based on the results, the FEM results proved the significant influence of the shape factors on the dynamic response of the HRCISS under both interior and exterior 3D vibrations when applied in multistory buildings. The lateral drift of the three‐story one‐bay buildings decreased with the decrement of shape factor with buildings of HRCISS installed in 1st story recording more reduction. Moreover, the deflection in the structural slab under the HRCISS decreased for lower shape factor bearings. Nevertheless, the reduced deflection was less affected by the level of the machine‐equipped story. The rubber layer also stiffened in shear and compression directions with a higher shape factor.
New York State’s WAVE Method - Evaluation of a Method for Water Quality Monitoring by Citizen Scientists using Benthic Macroinvertebrates
Authors: Onion Alene M. , Smith Alexander J. , Duffy Brian T. 
Published: December 2022

AbstractNew York State Department of Environmental Conservation (NYSDEC) has developed a robust citizen science macroinvertebrate sampling method. The metric relies on the presence and not the absence of key macroinvertebrates and therefore is resistant to collection and sorting errors. It identifies unimpaired streams with high confidence (0.1% type 1 errors) and at a reasonable efficiency compared to NYSDEC’s multimetric index of biological integrity (54%). We rank remaining stream samples for further investigation using a calculated probability of impairment. This method is valuable as a tool for large monitoring programs with limited resources for quality assurance checks. The value of this method goes beyond data collection, however, as data of known quality is an effective communication tool between citizen scientists and state regulatory agencies and/or local decision makers.
Continuous and discrete data assimilation with noisy observations for the Rayleigh-Bénard convection: a computational study
Authors: Hammoud Mohamad Abed El Rahman , Le Maître Olivier , Titi Edriss S. , Hoteit Ibrahim , Knio Omar 
Published: December 2022

AbstractObtaining accurate high-resolution representations of model outputs is essential to describe the system dynamics. In general, however, only spatially- and temporally-coarse observations of the system states are available. These observations can also be corrupted by noise. Downscaling is a process/scheme in which one uses coarse scale observations to reconstruct the high-resolution solution of the system states. Continuous Data Assimilation (CDA) is a recently introduced downscaling algorithm that constructs an increasingly accurate representation of the system states by continuously nudging the large scales using the coarse observations. We introduce a Discrete Data Assimilation (DDA) algorithm as a downscaling algorithm based on CDA with discrete-in-time nudging. We then investigate the performance of the CDA and DDA algorithms for downscaling noisy observations of the Rayleigh-Bénard convection system in the chaotic regime. In this computational study, a set of noisy observations was generated by perturbing a reference solution with Gaussian noise before downscaling them. The downscaled fields are then assessed using various error- and ensemble-based skill scores. The CDA solution was shown to converge towards the reference solution faster than that of DDA but at the cost of a higher asymptotic error. The numerical results also suggest a quadratic relationship between the ℓ2 error and the noise level for both CDA and DDA. Cubic and quadratic dependences of the DDA and CDA expected errors on the spatial resolution of the observations were obtained, respectively.
Miklós Zrínyi’s Efforts in Strengthening the Military Defenses of Međimurje, Hungary
Authors: Padányi József , Ondrék József 
Published: December 2022

AbstractKnowledge of the terrain and its use are essential for successful combat. This paper highlights the importance of these facts through the deeds of general Miklós VII Zrínyi (1620—64). His efforts to strengthen the defense of Međimurje resulted in a complex defense system that actively used the terrain to its advantage, established primarily for the protection of the Kakonya Crossing. The selection of the location of Novi Zrin, its strengthening, and the construction of the Zrínyi Ditch all prove that he was thinking of a complex system, and actively used the terrain to his advantage.
Slit-Strip Ising Boundary Conformal Field Theory 1: Discrete and Continuous Function Spaces
Authors: Ameen Taha , Kytölä Kalle , Park S. C. , Radnell David 
Published: December 2022

AbstractThis is the first in a series of articles about recovering the full algebraic structure of a boundary conformal field theory (CFT) from the scaling limit of the critical Ising model in slit-strip geometry. Here, we introduce spaces of holomorphic functions in continuum domains as well as corresponding spaces of discrete holomorphic functions in lattice domains. We find distinguished sets of functions characterized by their singular behavior in the three infinite directions in the slit-strip domains, and note in particular that natural subsets of these functions span analogues of Hardy spaces. We prove convergence results of the distinguished discrete holomorphic functions to the continuum ones. In the subsequent articles, the discrete holomorphic functions will be used for the calculation of the Ising model fusion coefficients (as well as for the diagonalization of the Ising transfer matrix), and the convergence of the functions is used to prove the convergence of the fusion coefficients. It will also be shown that the vertex operator algebra of the boundary conformal field theory can be recovered from the limit of the fusion coefficients via geometric transformations involving the distinguished continuum functions.
Regularized conditional estimators of unit inefficiency in stochastic frontier analysis, with application to electricity distribution market
Authors: Zeebari Zangin , Månsson Kristofer , Sjölander Pär , Söderberg Magnus 
Published: December 2022

AbstractIn stochastic frontier analysis, the conventional estimation of unit inefficiency is based on the mean/mode of the inefficiency, conditioned on the composite error. It is known that the conditional mean of inefficiency shrinks towards the mean rather than towards the unit inefficiency. In this paper, we analytically prove that the conditional mode cannot accurately estimate unit inefficiency, either. We propose regularized estimators of unit inefficiency that restrict the unit inefficiency estimators to satisfy some a priori assumptions, and derive the closed form regularized conditional mode estimators for the three most commonly used inefficiency densities. Extensive simulations show that, under common empirical situations, e.g., regarding sample size and signal-to-noise ratio, the regularized estimators outperform the conventional (unregularized) estimators when the inefficiency is greater than its mean/mode. Based on real data from the electricity distribution sector in Sweden, we demonstrate that the conventional conditional estimators and our regularized conditional estimators provide substantially different results for highly inefficient companies.
Academics’ Attitudes Toward Engaging in Public Discussions: Experimental Evidence on the Impact of Engagement Conditions
Authors: Püttmann Vitus , Ruhose Jens , Thomsen Stephan L. 
Published: December 2022

AbstractGrowing demands and expectations on the side of policy makers and the public have changed the conditions for academics’ engagement in public discussions. At the same time, risks related to this engagement for the professional and even private lives of academics have become apparent. Conducting a survey experiment among 4091 tenured professors in Germany, we study how these conditions causally affect academics’ attitudes toward engaging. Consistent with the crowding-out of intrinsic motivation, we find less-positive attitudes when emphasizing demands for engagement by public authorities and public expectations toward science’s societal relevance. Effects are particularly strong among professors endorsing science–society relations. Moreover, effects are similar when highlighting risks associated with engagement, but more pronounced for females and younger professors. Emphasizing public support for academics’ engagement has no discernible effects. We conclude that considering individual incentive structures and safeguarding against negative repercussions may promote academics’ engagement and an adequate representation of the diversity of academics in the public.
Detecting large-scale underwater cracks based on remote operated vehicle and graph convolutional neural network
Authors: Cao Wenxuan , Li Junjie 
Published: December 2022

AbstractIt is of great significance to quickly detect underwater cracks as they can seriously threaten the safety of underwater structures. Research to date has mainly focused on the detection of above-water-level cracks and hasn’t considered the large scale cracks. In this paper, a large-scale underwater crack examination method is proposed based on image stitching and segmentation. In addition, a purpose of this paper is to design a new convolution method to segment underwater images. An improved As-Projective-As-Possible (APAP) algorithm was designed to extract and stitch keyframes from videos. The graph convolutional neural network (GCN) was used to segment the stitched image. The GCN’s m-IOU is 24.02% higher than Fully convolutional networks (FCN), proving that GCN has great potential of application in image segmentation and underwater image processing. The result shows that the improved APAP algorithm and GCN can adapt to complex underwater environments and perform well in different study areas.
Incidental finding of Clostridium perfringens on human corpses used for the anatomy course

Published: December 2022

AbstractPost-mortem specimens used for anatomy teaching are commonly embalmed using compositions of chemicals, with the objective to maintain tissue quality and to avoid putrefaction. Monitoring for bacterial or fungal contamination is becoming increasingly important especially when measures are taken to minimize exposure by chemicals such as formaldehyde. In this case, random swabs were taken from six corpses embalmed with ethanol-glycerin and Thiel embalming. Cultures and MALDI-TOF analyses yielded four cases of Clostridium perfringens contamination. C. perfringens is of special interest as a human pathogen. A potential source was identified in the containers filled with the moistening solution. Cross contamination with Clostridium species has likely occurred between corpses sharing the moistening solution and soaking the cover linen directly within the containers. To minimize any risk for those exposed, the moistening solutions were discarded and all equipment thoroughly disinfected. The specimens had to be cremated as they formed a potential source of Clostridium spores. Deviating from previous routines it was formalized that the cover linen must not be submerged in the moistening contains rather than moistening the specimens directly with dedicated vessels. Follow-up analyses yielded no further contamination with C. perfringens.

Published: December 2022

AbstractBiochar supported nano-scale zerovalent iron (nZVI/BC) for persulfate (PS) activation has been studied extensively for the degradation of pollutants on the lab scale, but it was rarely applied in practical soil remediation in the field. In this research, we developed a facile ball-milling method for the mass production of nZVI/BC, which was successfully applied to activate persulfate for the remediation of organic polluted soil on an in-situ pilot scale. In-situ high-pressure injection device was developed to inject nZVI/BC suspension and PS solution into the soil with a depth of 0–70 cm. The removal efficiency of target pollutants such as 2-ethylnitrobenzene (ENB, 1.47–1.56 mg/kg), biphenyl (BP, 0.19–0.21 mg/kg), 4-(methylsulfonyl) toluene (MST, 0.32–0.43 mg/kg), and 4-phenylphenol (PP, 1.70–2.46 mg/kg) at different soil depths was 99.7%, 99.1%, 99.9% and 99.7%, respectively, after 360 days of remediation. The application of nZVI/BC significantly increased the degradation rates of contaminants by 11–322%, ascribed to its relatively higher efficiency of free radical generation than that of control groups. In addition, it was found that nZVI/BC-PS inhibited soil urease and sucrase enzyme activities by 1–61% within 55 days due to the oxidative stress for microbes induced by free radicals, while these inhibition effects disappeared with remediation time prolonged (> 127 days). Our research provides a useful implementation case of remediation with nZVI/BC-PS activation and verifies its feasibility in practical contaminated soil remediation.

A CRITERION FOR HYPERSYMMETRY ON DISCRETE GROUPOIDS
Authors: FLORES F. 
Published: December 2022

AbstractGiven a Fell bundle
$\mathscr C\overset {q}{\to }\Xi $
over the discrete groupoid
$\Xi $
, we study the symmetry of the associated Hahn algebra
$\ell ^{\infty ,1}(\Xi \!\mid \!\mathscr C)$
in terms of the isotropy subgroups of
$\Xi $
. We prove that
$\Xi $
is symmetric (respectively hypersymmetric) if and only if all of the isotropy subgroups are symmetric (respectively hypersymmetric). We also characterise hypersymmetry using Fell bundles with constant fibres, showing that for discrete groupoids, ‘hypersymmetry’ equals ‘rigid symmetry’.
Democratic Illusions: The Protestant Campaign for Conscientious Objection in the Early Federal Republic of Germany
Authors: Bloch Brandon 
Published: December 2022

AbstractDuring the early-Cold-War controversy over West German rearmament, the Protestant Church emerged as a center of activism for the right of conscientious objection to military service, departing from decades of precedent. This article uses the dramatic about-face of the Protestant Church to throw new light on how West Germans reimagined democratic politics after Nazism. Building on recent challenges to paradigms of postwar liberalization, it argues that illusory narratives of the Nazi past played a key role in West Germany's transition to democracy. Protestant activists for the right of conscientious objection drew on an imagined legacy of anti-Nazi resistance to reframe the idea of “conscience,” long associated with patriotic loyalties, as a uniquely Protestant contribution to democratic culture. In doing so, they came to identify their church as a pillar of West German democracy, even as they ensconced tendentious accounts of the Nazi past in postwar law and politics.
On a planar Schrödinger–Poisson system involving a non-symmetric potential
Authors: Molle Riccardo , Sardilli Andrea 
Published: December 2022

AbstractWe prove the existence of a ground state positive solution of Schrödinger–Poisson systems in the plane of the form
\[ -\Delta u + V(x)u + \frac{\gamma}{2\pi} \left(\log|\cdot| \ast u^2 \right)u = b |u|^{p-2}u \quad\text{in}\ \mathbb{R}^2, \]where $p\ge 4$, $\gamma,b>0$ and the potential $V$ is assumed to be positive and unbounded at infinity. On the potential we do not require any symmetry or periodicity assumption, and it is not supposed it has a limit at infinity. We approach the problem by variational methods, using a variant of the mountain pass theorem and the Cerami compactness condition.
Pseudo-holomorphic dynamics in the restricted three-body problem
Authors: MORENO AGUSTIN 
Published: December 2022

AbstractIn this paper, we identify the five dimensional analogue of the finite energy foliations introduced by Hofer–Wysocki–Zehnder for the study of three dimensional Reeb flows, and show that these exist for the spatial circular restricted three-body problem (SCR3BP) whenever the planar dynamics is convex. We introduce the notion of a fiberwise-recurrent point, which may be thought of as a symplectic version of the leafwise intersections introduced by Moser, and show that they exist in abundance for a perturbative regime in the SCR3BP. We then use this foliation to induce a Reeb flow on the standard 3-sphere, via the use of pseudo-holomorphic curves, to be understood as the best approximation of the given dynamics that preserves the foliation. We discuss examples, further geometric structures, and speculate on possible applications.
