Identity, positioning, and platforms: A case study of an older job seeker in a community technology center
Authors: Kobrin Jennifer D'haem 
Published: November 2023

AbstractRequests by education and workforce‐related technologies to reveal intimate aspects of adult learners' identities have become a common practice in a platform society, where personal information is monetized for “free” products and services. This article uses a sociomaterial lens to investigate how an older job seeker in a community technology center positioned her identity in and through a variety of literacy practices as she engaged with technology platforms in her job search. Drawing from data gathered over a 5‐month period with this job seeker as part of a larger ethnographic case study, this article shows the centrality of identity production in navigating and making sense of technologies, which entails negotiating one's sense of self across both front‐end user interfaces and back‐end infrastructures. Practical implications include creating space for students' critical agency of platforms, which can lead to meaningful change in policies related to data collection.

AbstractOn the way to the real industrial applications of the metal matrix composite foams, the machining issue is highly critical in terms of dimensional accuracy, surface quality, and design diversity. Therefore, especially for lightweight automotive and aerospace components, the drilling machinability properties of cellular glass‐added aluminum composite foams were examined in this paper, and this is the first initiative in the literature specific to millimeter‐scale glass and aluminum‐zinc matrix combination. To comprehend the drilling properties, the outputs of thrust force, cylindricity, material removal rate, specific cutting coefficient, circularity error, damage factor, surface roughness, and chip formation were measured elaboratively. The results showed that cylindricity and damage factor of foams elevated with the increased feed rates (from 0.05 mm×rev−1 to 0.2 mm×rev−1) and cutting speeds (from 25 m×min−1 to 100 m×min−1). Maximum thrust force value reached up to 150 N for 0.2 mm×rev−1 feed and 25 m×min−1 cutting speed. Besides, specific cutting coefficient values ranged between 360 MPa and 114 MPa. The highest surface roughness of 58.3 μm was obtained with the lowest cutting speed of 25 m×min−1, and the long/continuous chip structure converted into a separate/short structure based on rising feed and cutting speeds.

AbstractModeling and theoretical description of gas transport through mixed matrix membranes synthesized by including a covalent organic framework are essential for the efficient design of these membranes. This paper reports a theoretical analysis of various permeation models for gas transport through covalent organic framework‐based mixed matrix membranes. The existing models, such as Bruggeman, Maxwell, and Lewis Nielson, were analyzed. The Maxwell model calculated the permeation through voids and filler by considering interfacial defects in the covalent organic framework mixed matrix membrane's structure. Hence, dual Maxwell model was used to estimate gas transport through mixed matrix membranes. The percentage absolute average relative error of the dual Maxwell model was found to be less than 4 %. The results suggest that the dual Maxwell model effectively describes gas transport through a covalent organic framework mixed matrix membrane.

Published: November 2023

AbstractOffshore wind turbines are utilized for wind power harvesting through wind farms installed in bodies of water, normally at sea. The blades of the wind turbine resist the airflow and rotate and generate useful mechanical energy. Most of these wind blades are made of synthetic glass and carbon fibers. Synthetic fiber has higher mechanical strength but is non‐biodegradable in nature. The hybrid synthetic and natural composite materials overcome the non‐biodegradable issues to a certain extent and exhibit higher mechanical strength. In this prelude, the present work utilizes sisal, jute and rubber with epoxy‐based hybrid material used for wind blade manufacturing. The hybrid composite materials used in the present work have the volume fraction of synthetic fibers, natural fibers, and resin as 40 %, and 30 %, respectively. CATIA modelling software package is utilized to design the three‐dimensional model of the wind blade and is imported into the ANSYS Workbench. The structural, harmonic, and modal analyses are carried out, and the performance of the wind blades made of different hybrid composite materials is compared. Further, the computational fluid dynamic study is carried out to visualize the proposed composite offshore wind turbine's flow distribution. The results revealed that the proposed hybrid glass/jute/epoxy composite material yields better results and is more suited for offshore wind blade manufacturing.

AbstractObjectiveThere is substantial inter‐individual variability in response to weight loss interventions and emerging evidence suggests that weight loss during the early weeks of an intervention may be predictive of longer‐term weight loss. This secondary analysis of data from a commercial program therefore examined 1) the associations between early weight loss (i.e., week 4) with final visit weight loss and duration on the program, and 2) other predictors of lower weight loss at final visit.MethodsClient charts of adults with overweight or obesity (N = 748) were analyzed. Clients were stratified into categories of weight loss at the week 4 (< and ≥2%, 3% and 4%) and final visits (< and ≥5% and 10%). Multivariate logistic regression was used to assess predictors of <5% and <10% final visit weight loss.ResultsThe odds ratios for losing <5% or <10% of weight at the final visit were higher (49.0 (95% CI: 13.84, 173.63) and 20.1 (95% CI: 6.96, 58.06)) for clients who lost <2% or <3% compared to those who lost ≥2% or ≥3% at week 4. Other predictors of not losing a clinically relevant amount of weight included female sex, use of higher calorie meal plans and shorter time in the program, among others. Those who lost ≥2% at week 4 also had a significantly greater percent program completion (109.2 ± 75.2% vs. 82.3 ± 82.4, p < 0.01) compared with those who did not meet the 2% threshold.ConclusionsLower 4‐week weight loss was identified as a strong predictor of not losing a clinically relevant amount of weight. These results may be useful for the early identification of individuals who can be targeted for additional counseling and support to aid in attaining weight loss goals.

Published: November 2023

AbstractObjectiveTracheostomy tube change is a multistep skill that must be performed rapidly and precisely. Despite the critical importance of this skill, there is wide variation in teaching protocols.MethodsAn innovative operant conditioning teaching methodology was employed and compared to traditional educational techniques. Medical student volunteers at a tertiary care academic institution (Albert Einstein College of Medicine) were recruited and randomly distributed into 2 groups: operant vs traditional (control). Following the educational session, each group was provided with practice time and then asked to perform 10 tracheostomy tube changes. Performance was recorded and scored by blinded raters using deidentified video recordings.ResultsThe operant learning group (OLG) demonstrated greater accuracy in performing a tracheostomy tube change than the traditional demonstration group. Twelve of 13 operant learners performed the skill accurately each time compared to 3 of 13 in the traditional group (P = 0.002). The median lesson time was longer for the OLG (535 seconds) than for the traditional group, (200 seconds P < 0.001). The average time per tracheostomy change was not significantly different between the 2 groups (operant learners mean 7.1 seconds, traditional learners mean 7.5 seconds, P = 0.427).DiscussionAlthough the operant conditioning methodology necessarily requires a greater time to teach, the results support this methodology over traditional learning modalities as it enhances accuracy in the acquired skill. Operant learning methodology is under consideration for other skills and education sessions in our program. Future steps include the application and adaptation of this education model to students and residents in other settings and fields.Implications for PracticeOperant learning is effective for teaching multistep skills such as tracheostomy tube changes with decreased error rates.

AbstractIn cancer radiotherapy (RT), each step can be digitalized, from CT simulation, planning, dose verification, and image guidance to treatment delivery. Therefore, RT may be the most digitized discipline in the field of internal medicine. Then, questions arise. What potential development opportunities does the development of network transmission technologies, such as blockchain and 5G, provide to promote the progress of tumor RT? What will the future of smart RT (SART) look like? The purpose of this article is to introduce briefly the main characteristics of blockchain and 5G transmission technologies and share ideas to imagine the “tomorrow” of smart RT, hoping to provide a more accurate, safe, and comfortable RT experience for patients in the future.
Ethical considerations of using system dynamics in participatory settings: a social‐ecological‐systems perspective
Authors: Amorocho‐Daza Henry , van der Zaag Pieter , Sušnik Janez 
Published: November 2023

AbstractThe social‐ecological systems (SES) approach elicits a broad understanding of some of the most pressing socionatural challenges (e.g. resource scarcity, biodiversity loss, and climate change) and the responsibility that humans have in addressing them. System dynamics has proven a powerful paradigm for dealing with complex SES‐related issues. Here we discuss some ethical considerations of using system dynamics (SD) to model SES, something that is often either overlooked or discussed as an isolated issue. Sustainable development and human rights are used as ethical standpoints across the modelling cycle, opening the discussion around guiding principles that need to be considered when modelling SES. Based on these, a set of guiding ethical questions are identified and classified across a participatory SD modelling cycle. This structured approach is a simple yet potentially useful tool for SD practitioners to examine the ethical implications of their modelling endeavours in the context of grand societal challenges. © 2023 The Authors.

AbstractDue to the manufacturability of highly well‐defined structures and wide‐range versatility in its microstructure, SiO2 is an attractive template for synthesizing graphene frameworks with the desired pore structure. However, its intrinsic inertness constrains the graphene formation via methane chemical vapor deposition. This work overcomes this challenge by successfully achieving uniform graphene coating on a trimethylsilyl‐modified SiO2 (denote TMS‐MPS). Remarkably, the onset temperature for graphene growth dropped to 720 °C for the TMS‐MPS, as compared to the 885 °C of the pristine SiO2. This is found to be mainly from the Si radicals formed from the decomposition of the surface TMS groups. Both experimental and computational results suggest a strong catalytic effect of the Si radicals on the CH4 dissociation. The surface engineering of SiO2 templates facilitates the synthesis of high‐quality graphene sheets. As a result, the graphene‐coated SiO2 composite exhibits a high electrical conductivity of 0.25 S cm−1. Moreover, the removal of the TMP‐MPS template has released a graphene framework that replicates the parental TMS‐MPS template on both micro‐ and nano‐ scales. This study provides tremendous insights into graphene growth chemistries as well as establishes a promising methodology for synthesizing graphene‐based materials with pre‐designed microstructures and porosity.

AbstractThe rational design of inexpensive metal electrocatalysts with exciting catalytic activity for overall water splitting (OWS) remains a significant challenge. Heterostructures of NiFe layered double hydroxides (NiFe‐LDHs) with abundant oxygen defects and tunable electronic properties have garnered considerable attention. Here, a self‐supporting heterostructured catalyst (named MoO3/NiFe‐NF) is synthesized via a hydrothermal method to grow NiFe‐LDH with oxygen vacancies (OV) in situ on inexpensive nickel foam (NF). Subsequently, MoO3 is anchored and grown on the surface of NiFe‐LDH by electrodeposition. The obtained catalysts achieved outstanding oxygen/hydrogen evolution reaction (OER/HER, 212 mV/85 mV@10 mA cm−2) performance in 1 m KOH. Additionally, when MoO3/NiFe‐NF is utilized as the cathode and anode in OWS, a current density of 10 mA cm−2 can be obtained as an ultralow battery voltage of 1.43 V, a significantly lower value compared to the commercial electrolyzer incorporating Pt/C and IrO2 electrode materials. Finally, density functional theory (DFT) calculations and advanced spectroscopy technology are conducted to reveal the effects of heterojunctions and OV on the internal electronic structure of the electrical catalysts. Mainly, the present study provides a novel tactic for the rational design of remarkable, low‐cost NiFe‐LDH electrocatalysts with heterostructures for OWS.

Published: November 2023

ABSTRACTObjectivesFetal premature atrial contractions (PAC) are usually benign but may be associated with congenital heart defect (CHD) and tachyarrhythmia, which in turn carry a risk of cardiac failure and fetal death. We aimed to explore the frequency of adverse outcome and to identify risk factors for tachyarrhythmia in pregnancies complicated by fetal PAC.MethodsThis was a retrospective cohort study of fetuses diagnosed with PAC at two academic centers in Amsterdam, The Netherlands, between 2007 and 2022. Cases with a congenital anomaly and those with a prior diagnosis of CHD or other arrhythmias were excluded. M‐mode and Doppler tracings were reanalyzed and the frequency of PAC was recorded. The incidence of the following adverse outcomes was examined: underlying CHD not identified at the 20‐week fetal anomaly scan, tachyarrhythmia, other arrhythmia, administration of antiarrhythmic therapy and death. Risk factors for tachyarrhythmia were analyzed using odds ratios (OR).ResultsIn 24.1% of 1439 referred cases, PAC resolved before confirmation at the fetal medicine unit (FMU). Of the 939 included cases with confirmed PAC, the total incidence of adverse outcome was 6.8% (64/939). CHD was diagnosed in 14 (1.5% (95% CI, 0.9–2.5%)) cases, of which eight were diagnosed prenatally and six postnatally. Compared with baseline, the incidence of CHD was higher in the presence of fetal PAC (OR, 1.8 (95% CI, 1.0–3.3); P = 0.034). Tachyarrhythmia occurred prenatally and/or postnatally in 32 (3.4%) cases, of which eight (25.0%) showed signs of cardiac failure, and in 23 (71.9%) cases, antiarrhythmic therapy was required. No cases of tachyarrhythmia led to fetal or infant death. Risk factors for tachyarrhythmia were PAC with short runs of supraventricular tachycardia (OR, 98.7), blocked PAC (OR, 30.3), PAC in bigeminy (OR, 21.8), frequent PAC (one per 5–10 beats) (OR, 6.9), signs of cardiac failure (OR, 14.2) and the presence of a foramen ovale aneurysm (OR, 5.0).ConclusionsPAC are generally benign and often resolve spontaneously. However, fetuses with an irregular heart rhythm should be referred for advanced ultrasonography, which should focus on classifying the type of PAC and risk of adverse outcome. When risk factors for tachyarrhythmia are identified, weekly fetal heart‐rate monitoring is advised until resolution of the PAC. In the absence of risk factors, standard obstetric care may be sufficient, with additional instructions to report reduced fetal movements. Should tachyarrhythmia or cardiac failure develop, referral back to the FMU is indicated. © 2023 The Authors.

Published: November 2023

Abstract
We investigate the twelve-dimensional gauge-Higgs unification models with an eight- dimensional coset space as the extra space. For each model, we apply the coset space dimensional reduction procedure and examine the particle contents of the resulting four-dimensional theory. All combinations of inputs to the procedure are exhaustively analyzed under several assumptions. As a result, some twelve-dimensional SO(18) gauge theories lead to models of the SO(10) × U(1) grand unified theory in four dimensions, where fermions of the Standard Model appear in multiple generations along with scalars that may break the electroweak symmetry. The representations of the obtained scalars and fermions are summarized.
Phylogeographic analysis points toward invasion of the Timanfaya National Park (Lanzarote; Canary Islands) by a translocated native plant (Rumex lunaria)

AbstractRumex lunaria is an endemic shrub of the Canary Islands, which is colonizing the Timanfaya National Park (TNP) in Lanzarote. Whether the arrival of R. lunaria to Lanzarote has been natural or by human intervention is still a matter of debate. To address this question, 100 specimens of R. lunaria were collected from the seven main Canary Islands, and genetic analysis of four chloroplast DNA loci were performed, covering a total length of 4809 nucleotide positions. Multiple alignments revealed 49 nucleotide substitutions, which define 30 different haplotypes. Island-specific haplotypes were found in Tenerife, La Gomera, La Palma and Gran Canaria, with the greatest diversity found in the first island. Interestingly, the unique haplotype detected in El Hierro is shared with almost all plants from Lanzarote (95%), including all individuals sampled in the TNP. The most frequent haplotype present in Gran Canaria was detected in only one sample from Lanzarote (5%). These results were corroborated by a robust phylogenetic analysis, which supports the hypothesis of a common origin of R. lunaria populations from El Hierro and the vast majority of those from Lanzarote. In addition, this study rules out the genetic singularity of the R. lunaria specimens that are colonizing the TNP.
Role of the hydrolytic-acidogenic phase on the removal of bisphenol A and sildenafil during anaerobic treatment

Published: November 2023

AbstractThis paper presents the main results of the removal of two pharmaceutical and personal care products (PPCPs), bisphenol A (BPA) and sildenafil (SDF), by applying anaerobic biological batch tests. The biomass used was previously acclimatized and the experiment lasted 28 days. The effect of factors such as compound (BPA and SDF), concentration and type of inoculum was assessed, considering the factorial experimental design. The results indicated that evaluated factors did not significantly affect the PPCPs elimination in the evaluated range with a confidence level of 95%. On the other hand, the removal percentages obtained with BPA were mainly related to mechanisms, such as sorption and abiotic reactions. Regarding SDF, biodegradation was the predominant mechanism of removal under the experimental conditions of this study; however, the degradation of SDF was partial, with percentages lower than 43% in the tests with hydrolytic/acidogenic inoculum (H/A) and lower than 41% in the tests with methanogenic inoculum (MET). Finally, these findings indicated that hydrolysis/acidogenesis phase is a main contributor to SDF biodegradation in anaerobic digestion. The study provides a starting point for future research that seeks to improve treatment systems to optimize the removal of pollutants from different water sources.
