Published: July 2023

Background
The Preterm Birth Initiative (PTBi)–Rwanda conducted a cluster randomized controlled trial to assess the impact of group antenatal care (group ANC) on preterm birth, using a group ANC approach adapted for the Rwanda setting, and implemented in 18 health centers. Previous research showed high overall fidelity of implementation, but lacked correlation with provider self-assessment and left unanswered questions. This study utilizes a mixed-methods approach to study the fidelity with which the health centers’ implementation followed the model specified for group ANC.

Methods
Implementation fidelity was measured using two tools, repeated Model Fidelity Assessments (MFAs) and Activity Reports (ARs) completed by Master Trainers, who visited each health center between 7 and 13 times (9 on average) to provide monitoring and training over 18 months between 2017 and 2019. Each center’s MFA item and overall scores were regressed (linear regression) on the time elapsed since the center’s start of implementation. The Activity Report (AR) is an open-ended template to record comments on implementation. For the qualitative analysis, the ARs from the times of each center’s highest and lowest MFA score were analyzed using thematic analysis. Coding was conducted via Dedoose, with two coders independently reviewing and coding transcripts, followed by joint consensus coding.

Results
A total of 160 MFA reports were included in the analysis. There was a significant positive association between elapsed time since a health center started implementation and greater implementation fidelity (as measured by MFA scores). In the qualitative AR analysis, Master Trainers identified key areas to improve fidelity of implementation, including: group ANC scheduling, preparing the room for group ANC sessions, provider capacity to co-facilitate group ANC, and facilitator knowledge and skills regarding group ANC content and process. These results reveal that monitoring visits are an important part of acquisition and fidelity of the “soft skills” required to effectively implement group ANC and provide an understanding of the elements that may have impacted fidelity as described by Master Trainers.

Conclusions
For interventions like Group ANC, where “soft-skills” like group facilitation are important, we recommend continuous monitoring and mentoring throughout program implementation to strengthen these new skills, provide corrective feedback and guard against skills decay. We suggest the use of quantitative tools to provide direct measures of implementation fidelity over time and qualitative tools to gain a more complete understanding of what factors influence implementation fidelity. Identifying areas of implementation requiring additional support and mentoring may ensure effective translation of evidence-based interventions into real-world settings.
Dupilumab-Induced Pancreatitis
Authors: Jasti Vivek V. , McCarthy Sean T. , Govani Shail M. 
Published: July 2023

ABSTRACT
Drug-induced pancreatitis (DIP) is a rare cause of pancreatitis with an extensive and growing list of offending medications. Drawing a causative relationship between a medication and pancreatitis can be challenging, requiring a thorough workup to exclude other potential etiologies. By using scoring systems to identify DIP, we have identified another case of suspected DIP. In this study, we present a case of pancreatitis 10 days after initiation of dupilumab. An evaluation for other causes was unrevealing. As dupilumab use increases, providers should be aware of this possible adverse effect.
Don’t Stop Me Now: Cross-Border Commuting in the Aftermath of Schengen
Authors: Parenti Angela , Tealdi Cristina 
Published: July 2023

Abstract
A Single European Labour Market has not been achieved yet, despite strong efforts in promoting cross-country labour mobility. In this paper, we assess the effectiveness of one of the most important policies implemented to reach this goal: the Schengen Agreement. Using data from the European Labour Force Survey, we show that the individual probability to become a cross-border commuter after the entrance of Switzerland in the Schengen area increased by 0.5 and 4 percentage points among labour force individuals and inter-regional commuters, respectively. We also show evidence of a substantial redirection of internal inter-regional commuters to Swiss regions.
A Higher-Order Markov Model for a Hybrid Inventory System with Probabilistic Remanufacturing Demand
Authors: Dhaiban Ali Khaleel 
Published: July 2023

Abstract
This study develops a higher-order Markov model (HOM) for an inventory system with remanufacturing, substitution, and lost sales. Defective and disposed items are other factors that are considered in addition to probabilistic demand for both manufacturing and remanufacturing items. One year is the warranty period for items manufactured, and items sold return from customers to the manufacturer in increasing cumulative percentages over the months of the year. To the best our knowledge, a higher-order Markov model has rarely been used in a hybrid inventory system. The challenge is how to determine the steady state of the system with the probable demand for manufacturing and remanufacturing. We propose a new search algorithm to select the best control strategy from several strategies, and then compare it with the two-phase local search algorithm. Each state deals with (12) a probabilistic demand (policy), so the system steady state is set to (22632) policies in total for each production plan. The results showed profit maximization using the new search algorithm compared with the two-phase local search algorithm. Also, an increase in defective and returned items over time, and therefore an increase in remanufactured items. But it does not satisfy all the demand, so manufacturing increases over time due to substitution. Substitution strategy leads to increase the expected average profit.
Does Malapportionment Favor the Republican Party?
Authors: Tamas Bernard 
Published: July 2023

Abstract
This paper examines electoral bias within US politics, including as it relates to malapportionment in the US Senate and Electoral College. Specifically, with the Republican Party gaining significant support in rural areas and the Democratic Party becoming concentrated in urban areas, there is concern that the US electoral system increases the probability that the Republican Party will win a much higher percent of Senate seats than its public support and repeatedly win the presidency without having won a plurality of votes, as was the case in 2000 and 2016. I explore this concern using a relatively new measure called the Directional Proportionality Index (DPIx). Applying it to the Electoral College since 1872 and the US Senate since 1918, this paper demonstrates that while there does exist a small pro-Republican bias in the Electoral College owing to malapportionment, the pro-Republican malapportionment bias in Senate races is far more substantial. However, as long as the percent vote for Democratic and Republican presidential candidates remains close due to partisan polarization, this small bias in the Electoral College is likely enough to lead to more cases whereby the Republican Party loses the popular vote but still wins control over the White House and the United States Congress.

Boundary contact problems with regard to friction of couple-stress viscoelasticity for inhomogeneous anisotropic bodies (quasi-static cases)
Authors: Gachechiladze Roland , Gachechiladze Avtandil 
Published: July 2023

Abstract
In this paper, quasi-statical boundary contact problems of couple-stress
viscoelasticity for inhomogeneous anisotropic bodies with regard to friction are investigated.
We prove the uniqueness theorem of weak solutions
using the corresponding Green’s formulas and positive definiteness of the potential energy.
To analyze the existence of solutions, we equivalently reduce the problem
under consideration to a spatial variational inequality.
We consider a special parameter-dependent regularization of this variational inequality
which is equivalent to the relevant regularized variational equation
depending on a real parameter, and study its solvability by the Galerkin approximate method.
Some a priori estimates for solutions of the regularized variational
equation are established and with the help of an appropriate
limiting procedure, the existence theorem for the original
contact problem with friction is proved.

Authors: Kasimova Nina , Zhuk Tetiana , Tsyganivska Iryna 
Published: July 2023

Abstract
We consider the optimal control problem of a non-linear system of differential inclusions with fast-oscillating parameters on semi-axes. Using the averaging method, we find an approximate solution for the optimal control of non-linear differential inclusions with fast-oscillating coefficients on a semi-axes.
Thus, we prove the convergence of the optimal controls of the initial control problem to the optimal process of the averaged problem and the convergence of the corresponding cost functionals.

Published: July 2023

Abstract
This article presents the new linked employee-employer study of the Socio-Economic Panel (SOEP-LEE2), which offers new research opportunities for various academic fields. In particular, the study contains two waves of an employer survey for persons in dependent work that is also linkable to the SOEP, a large representative German annual household panel (SOEP-LEE2-Core). Moreover, SOEP-LEE2 includes two waves of self-employed surveys based on self-employed in the SOEP-Core (SOEP-LEE2-Self-employed) and three additional representative employer surveys, independent of the SOEP in terms of sampling employers (SOEP-LEE2-Compare). Survey topics include digitalisation and cybersecurity, human capital formation, COVID-19, and human resource management. Here, we describe the content, survey design, and comparability of the different datasets in the SOEP-LEE2 to potential users in different disciplines of research.
Effect of MIMO scheme on MWIR FSO link & comparison with SWIR wavelength in the presence of different visibility and strong turbulence circumstances
Authors: Mukherjee Shibabrata , Paul Sujoy , Mazumdar Saswati 
Published: July 2023

Abstract
In this article, the authors analyse the performance of the “multiple input multiple output (MIMO)” technique on a free space optical (FSO) communication link using the mid wavelength infrared (MWIR) and commonly used short wavelength infrared (SWIR) in the presence of various visibility conditions like clear weather, light haze, dense haze, fog, etc., and strong turbulence regime. A 5 km link range has been considered with different diversity MIMO schemes. The performance analysis has been made for both wavelengths in terms of bit error rate (BER) and link outage probability. As the MIMO diversity is increased, the performance has been improved compared to the single input single output (SISO) scheme. In the presence of foggy conditions and higher turbulence strength, the MWIR wavelength works properly, whereas the SWIR wavelength has not worked for the same signal to noise (SNR) ratio and the same link distance.
Analysis of throughput and error rate of 16-QAM, 64-QAM, and 256-QAM O-NOMA waveforms
Authors: Kumar Arun , Gour Nidhi , Sharma Himanshu 
Published: July 2023

Abstract
This study presents a comprehensive analysis of the throughput performance, spectrum efficiency, and block error rate (BLER) of optical non-orthogonal multiple access (O-NOMA) waveforms using 16-quadrature amplitude modulation (QAM), 64-QAM, and 256-QAM modulation schemes. The aim is to assess the trade-offs between data rate, spectral efficiency, and error performance in O-NOMA systems. The analysis reveals that higher-order modulations, such as 64-QAM and 256-QAM, offer higher data rates and improved spectrum efficiency compared to 16-QAM. Furthermore, the study investigates the spectrum performance of the O-NOMA waveforms. The results indicate that higher-order modulations may utilise the spectrum more efficiently, maximising the data throughput within the available bandwidth. Moreover, the BLER analysis provides insights into the error performance of the O-NOMA waveforms. It quantifies the probability of errors occurring in a block of transmitted data and evaluates the system’s reliability. The analysis reveals that 256-QAM O-NOMA achieves lower BLER and high throughput in uplink and downlink as compared with the 16 and 64-QAM O-NOMA frameworks.

Published: July 2023

Abstract

Objectives
To understand the effect of 50-g oral glucose tolerance test (OGTT) on fetal celiac artery and superior mesenteric artery (SMA) Doppler parameters.

Methods
A total of 43 healthy pregnant women followed in our hospital were included in the study. All Doppler parameters of the celiac artery and SMA (peak systolic velocity (PSV); pulsatility index (PI); resistance index (RI); systolic/diastolic ratio (SD); time average maximum velocity (TAMAX)) were obtained by ultrasonography before and 1 h after OGTT.

Results
The mean PSV value of the celiac artery decreased statistically significantly after OGTT (37.29 ± 11.96 cm/s; 29.51 ± 10.07 cm/s; p=0.002). While the mean of the PI was 2.09 ± 0.57 before the test, it was found to be 1.84 ± 0.64 after the test (p=0.027). Mean PSV (39.82 ± 13.07 cm/s; 35.19 ± 15.27 cm/s; p=0.104) and PI (2.21 ± 0.65; 2.11 ± 0.80; p=0.375) values of SMA were also found to be decreased without statistically significancy.

Conclusions
The data obtained from our study reveals that the PSV and PI values of celiac artery and SMA slightly decrease after OGTT.
The Offensiveness Torts
Authors: Abraham Kenneth S. , White G. Edward 
Published: July 2023

Abstract
Three established torts require the defendant’s behavior to be “offensive” or “highly offensive” in order to be actionable: offensive battery, public disclosure of true private facts, and intrusion on seclusion. Although what links these “offensiveness” torts together has not been recognized before, this Article demonstrates that they occupy a sub-category of tort liability that is coherent, insight-generating, and useful. The torts developed at different times and in a sense for different reasons, but all three rest on the same principle: the idea that individual autonomy involves not only inviolable bodily space, but also inviolable private and informational space. What counts as actionable wrongdoing for these torts depends on the cultural context, because what is considered offensive conduct may vary, as cultural conditions change. The typical victim (or observer) of one of these torts must plausibly have the reaction “How dare you?” for the offensiveness element of the tort to be satisfied. That is what links these three superficially disparate torts together, and warrants understanding them together, as protections against invasions of the different forms of inviolable space that are a core feature of every individual’s autonomy.
Novel metaphor and embodiment: comprehending novel synesthetic metaphors
Authors: Zhong Yin , Ahrens Kathleen , Huang Chu-Ren 
Published: July 2023

Abstract
Linguistic synesthesia links two concepts from two distinct sensory domains and creates conceptual conflicts at the level of embodied cognition. Previous studies focused on constraints on the directionality of synesthetic mapping as a way to establish the conceptual hierarchy among the five senses (i.e., vision, hearing, taste, smell, and touch). This study goes beyond examining the directionality of conventionalized synesthetic terms by adopting a Conceptual Metaphor Theory approach (i.e., the Conceptual Mapping Model) to test if conventional synesthetic directionality still holds when it comes to novel metaphorical expressions. The subjects, 308 native English speakers, are asked to judge the degree of commonness, appropriateness, understandability, and figurativeness in order to measure the degree of comprehensibility of novel synesthetic metaphors. Our findings demonstrate that novel synesthetic metaphors that follow conventional directionality are considered more common, more appropriate, and easier to comprehend than those that violate conventional mapping principles; they are also judged as more literal than those that do not follow conventional directionality. This study explores linguistic synesthesia from the perspective of comprehension of novel synesthetic metaphors, posits a pivotal position for mapping principles in synesthetic directionality, and supports an embodied account of linguistic synesthesia.
A Compass for What Matters: Applying Virtue Ethics to Information Behavior
Authors: Gorichanaz Tim 
Published: July 2023

Abstract
Out of the three major approaches to ethics, virtue ethics is uniquely well suited as a moral guide in the digital age, given the pace of sociotechnical change and the complexity of society. Virtue ethics focuses on the traits, situations and actions of moral agents, rather than on rules (as in deontology) or outcomes (consequentialism). Even as interest in ethics has grown within information behavior (IB), there has been little engagement with virtue ethics. To address this lacuna and demonstrate further research opportunities, this article provides an overview of virtue ethics for application in IB (broadly defined). It provides a primer on virtue ethics, gives examples of existing IB work that is compatible with virtue ethics, and suggests avenues for further virtue-oriented research in IB.
Chaotic characteristics and mixing performance of pseudoplastic fluids in a stirred tank
Authors: Zhang Xiang , Si Wen , Zhao Chengzhi , Luan Deyu 
Published: July 2023

Abstract
The key for improving the mixing efficiency of pseudoplastic fluids is to enhance the chaotic degree in the flow field. The xanthan gum solution was used to study the chaotic characteristics and mixing performance in a stirred tank with the impeller of perturbed six-bent-bladed turbine. Based on the velocity time series collected by the experiment of particle image velocimetry (PIV), the distributions of the largest Lyapunov exponent (LLE) and Kolmogorov entropy (K entropy) of the system were obtained through the programming calculation using the software MATLAB (R2016a) for characterizing the chaotic degree. The mixing performance of the fluid was numerically investigated using the Computational Fluid Dynamics package, and the velocity distributions were compared with the results obtained by the experiment of PIV. The relevance between the chaotic degree and the mixing performance was clarified. Results showed that the numerical results of velocity distributions agreed well with the experimental data which validated the Computational Fluid Dynamics model established. When the speed reached 600 rpm, the LLE and K entropy climbed the maximal values at the same time, which meant the greatest degree of chaos, and the mixing energy per unit volume was minimal at that moment, which was corresponding to the highest mixing efficiency. As the speed increased further, the LLE and K entropy decreased instead, which meant the chaos reduction, and the corresponding mixing energy per unit volume increased with the low mixing efficiency.

Preparation and application of foamed ceramic panels in interior design
Authors: Wang Bin 
Published: July 2023

Abstract
A new type of foam ceramics was prepared with fly ash (CFA). Before sintering, the CFA underwent alkali activation, resulting in an even layer of hydroxy sodalite crystals covering the CFA particles. The pre-treatment of the CFA-alkali-activated material caused it to exhibit a reaction in sintering. The foamed ceramics had the best qualities when sintered at 1,300°C; the leaching toxicity studies of a material used in interior design revealed that during sintering.
