Authors: Polim Hidayat
Published: February 2023

This study gathered data from Pre-Service Teachers (PSTs) in preparation for teaching practicum at a university in Indonesia. The study utilized a qualitative approach to comprehend the current practices in preparing participants of the teaching practicum and identifying the essential aspects needed to be addressed by research participants (PSTs, Practicum Supervisors, and Classroom Supervisors). The study found several courses that have helped PSTs in scaffolding their journey toward their practicum, including curriculum and material development, micro-teaching, and practicum orientation. However, as PSTs conduct their practicum, the dynamic and challenges were inevitably evident throughout the journey. The skills and knowledge they have studied have not been able to be fully utilized in the teaching practicum. These are reflected in their responses related to their confidence handling classroom management, language skills, identifying their role as practicum teacher, and the effectiveness of the current practice of classroom observation. The study concludes the importance of adjusting and reflecting on relevant aspects and knowledge that need to be integrated into the preparation of the teaching practicum. A systematic and continual innovation will need to be the focus of stakeholders in the teacher education prior to the teaching practicum.

End-stage kidney disease: towards shared decision-making and patient-reported outcomes
Authors:   , van Eck van der Sluijs Anita
Published: February 2023

Over 12% of the Dutch population has chronic kidney disease. As chronic kidney disease progresses toward end-stage kidney disease, patients receive education on treatment options (kidney transplantation, dialysis, conservative care), with an increased focus on shared decision-making in recent years. This education process may lead to the choice of a form of dialysis, namely hemodialysis (dialysis through the bloodstream) or peritoneal dialysis (abdominal dialysis). Many studies have been done in the past on the risk of morbidity/mortality of dialysis patients, but there is increasing demand for studies on patient-reported outcomes, such as health-related quality of life.
The aim of this thesis is to gain insights in (1) patient education and shared decision-making, (2) traditional clinical outcomes of dialysis such as bleeding, hospitalization, technique failure and peritoneal dialysis peritonitis, and (3) an important patient-reported outcome; health-related quality of life.
Part I of this thesis shows that the commitment of healthcare professionals and availability of effective systems, that incorporate good practices, are vital for optimal patient education and shared decision-making.
Part II shows that that the occurrence of certain ‘traditional’ clinical outcomes differs between dialysis modalities, with a higher bleeding risk for hemodialysis patients but a higher hospitalization risk for peritoneal dialysis patients, mainly related to infections. Moreover, peritoneal dialysis-related infections lead to a high technique failure rate, which calls for more attention to infection prevention or a different approach to the treatment of specific peritoneal dialysis-related infections.
Part III shows that health-related quality of life is an important patient-reported outcome, but the effect of different dialysis modalities on health-related quality of life is not yet clear.
In summary, this thesis shows a shifts toward shared decision-making and the importance of patient-reported outcomes for patients with end-stage kidney disease.

Authors: Gwyn Jennifer C. V. , Veenith Tonny
Published: February 2023

Malignant middle cerebral artery (MCA) infarcts occur in a small subset of patients with ischaemic strokes and lead to high levels of disability and mortality. Over the last 10 years, surgical interventions, in the form of decompressive craniectomies, have become more popular. There is insufficient evidence to support current medical treatments including mannitol, glycerol, steroids, hypertonic saline, and therapeutic hypothermia. Several randomised controlled trials of early decompressive craniectomies in younger patients have shown a significant improvement in functional outcomes and mortality. Questions still need answering regarding the timing of this surgery, long-term survival benefits, and age thresholds. In this review article we will discuss the evidence and uncertainties surrounding the management of malignant MCA infarcts.
A Review of the Latest Advancements in Ovarian Cancer Care Featured at ESMO 2022
Authors: Scott Brigitte
Published: February 2023

Ovarian cancer is the seventh most commonly diagnosed cancer among females and the most lethal gynaecologic malignancy globally because of its vague presentation, insidious nature, recurrence, and drug resistance. There is a pressing need to improve survival and quality of life in patients with ovarian cancer in the context of rising global incidence, high risk of relapse, and poor prognosis. Presentations at the European Society for Medical Oncology (ESMO) Congress 2022 from 9th–13th September in Paris, France, showed the breadth and depth of research in ovarian cancer, including a first look at the highly anticipated data from Phase III studies on the impact on overall survival (OS) of poly(ADP-ribose) polymerase (PARP) inhibitors as first-line maintenance therapy. Clinically meaningful OS benefit was shown with olaparib at 5 years’ follow-up in PAOLA-1 and at 7 years’ follow-up in SOLO1. These positive results are a breakthrough in ovarian cancer treatment and are an important indicator that improvements in progression-free survival (PFS) may translate into OS benefits. Studies in which PARP inhibitors showed clinically meaningful efficacy, but OS data remain immature, include PRIMA, in which niraparib as a first-line maintenance therapy maintained clinically significant improvement in progression-free survival at 3.5 years’ follow-up. Research into chemotherapy resistance using a glucocorticoid receptor modulator in combination with nab-paclitaxel as part of second-line treatment showed that glucocorticoid receptor modulation can improve the efficacy of chemotherapy. Pre-clinical and early phase clinical studies are investigating a range of approaches for the treatment of ovarian cancer such as development of a chimeric antigen receptor T cell therapy, combination of a PARP inhibitor and an immune checkpoint inhibitor, and a bispecific antibody. Developments in these areas are awaited with interest. There is considerable focus on biomarkers for prognosis and progression in ovarian cancer, including research on breast related cancer antigen and homologous recombination deficiency testing, cancer antigen 125 (CA125) decline, and circulating tumour DNA (ctDNA); however, wider genetic testing, improved education of physicians on the importance of testing, and increased access to testing are recommended to optimise treatment and disease prevention. The research in ovarian cancer presented at ESMO 2022 marks important progress in this field.

Land use, like any other natural resource, involves loads on nature and causing harm to it. Therefore, completely harmless production today is considered impossible. Because of this, goals have been identified that establish the rationality of land use. Such goals include, taking into account natural conditions and economic indicators in the corresponding territory, ensuring the interests of society as a whole, the efficiency of the production process, as well as the protection of the quality of land and its reproduction. These goals are always unchanged, and their achievement depends on the technological development of production, the economic level, and the needs of society. In this article, the agricultural suitability level of Khachmaz district land was analyzed based on the cadastral database created on the basis of GIS technologies. It was also noted the need to take a number of measures to reduce the risk of soil erosion.

Published: February 2023

In the last decade, digital elevation models (DEMs) based on surveys from unmanned aerial vehicles (UAVs) have been increasingly used to obtain quantitative characteristics of geomorphological objects of the coastal systems. The information of the morphological objects structure obtained with the help of such DEMs makes it possible to refine the details of the large coastal forms development. The aim of the work is to identify micro relief forms on the Dolgaya Spit, in particular, beach ridges, based on UAV survey. The need for filtering both at the point cloud level and after the creation of a DEM before conducting a geomorphological analysis is discussed in the article. An automated procedure for identifying the lines of the coastal ridges crests based on the DEM is given. Coastal ridges in the central part of the Dolgaya Spit and calculation of their morphometric characteristics are presented. Their average height is about 0.5 m, the width — 16 m. Analysis of the automated identification of coastal ridges crests and their comparison with ground-based observations showed a significant scatter in the values of morphometric characteristics along the ridges and, as a result, a bias in their point estimates during direct ground-based measurements.

Published: February 2023

The results of computational and experimental studies of the parameters of a parametric light generator in the mid-IR range are presented. One of the main problems of OPO in the near and mid-IR range (1-8 μm) is the high divergence of the output radiation. The purpose of this study is to improve the spectral and amplitude-spatial characteristics for the out-of-cavity scheme of the IR-OPO ring resona-tor. In an in vitro experiment simulating the radiation of an IR parametric laser, the dependences of the spectral width and quality factor of the radiation of a tunable laser frequency on the wavelength were obtained. It is shown that the improved optical-geometrical parameters of the out-of-zone OPO scheme made it possible to achieve high values of the spectral radiation width (≤ 1 cm-1) and quality factor (≥ 4.106). It is shown that such a developed scheme of an out-of-cavity OPO based on new chalcogenide crystals will expand its application in the mid- and far-IR ranges.

Authors: Tuki Daniel
Published: February 2023

Using novel survey data collected from the states of Kaduna and Edo in Nigerias Northern and Southern Regions respectively, this study examined the relationship between educational attainment and attitudes towards gender equality. The measure for attitudes towards gender equality was derived from the question, A university education is more important for a boy than a girl, with responses on a 5-point scale ranging from strongly agree to strongly disagree. Educational attainment was measured on a 10-point scale ranging from no formal schooling to masters degree or higher. Educational attainment was found to correlate positively with support for gender equality in the two states. Being female increased the likelihood of supporting gender equality in both states, while Muslim self-identification reduced the likelihood of supporting gender equality only in Kaduna.
Agendas, Decisions, and Autonomy: How Government Lawyers Shape Judicial Behavior
Authors: Pavone Tommaso
Published: February 2023

Social scientists have long traced how private attorneys influence judicial behavior. By contrast, we lack a comparative agenda probing how government lawyers impact the courts. This paper identifies three ways that government attorneys influence judicial behavior: by shaping judicial agendas, decisions, and autonomy. I attribute each mode of influence to a type of government lawyer public prosecutors, government litigators, and executive branch attorneys and illustrate the mechanisms driving their influence over judges via examples. First, I spotlight how government lawyers in law enforcement roles can wield a “politics of discretion” to shape judges agendas by withholding or prioritizing lawsuits. Next, I highlight how attorneys representing governments in court can engage in a “politics of positionality,” leveraging their role as intermediaries and repeat players to influence judgments. Finally, I chronicle how attorneys in the executive branch can weaponize their legal training to undermine judicial independence what I call “power politics, lawyer-style.”
Deriving a theory of learning from social movement practices
Authors: Atta Mai , Holst John
Published: February 2023

The field of Adult Education is rich with general theories of learning but limited in terms of theories that inform social movement learning (SML). Today, there are several conceptualizations of SML, but little learning theory development based directly on empirical studies of SML. This article aims to present findings from a systematic literature review of empirical studies on social movement learning (SML). We collected and identified 69 empirical studies focusing on adult learning and education within social movements for this literature review. We purposely focused on empirical research studies and did not include works that conceptualise or theorise social movement learning outside of actual empirical studies of SML. From our review of empirical studies, we have identified five elements we believe could serve as the foundation of a theory of learning and education in social movements.
CASBERT: BERT-based retrieval for compositely annotated biosimulation model entities
Authors: Munarko Yuda , Rampadarath Anand , Nickerson David P.
Published: February 2023

Maximising FAIRness of biosimulation models requires a comprehensive description of model entities such as reactions, variables, and components. The COmputational Modeling in BIology NEtwork (COMBINE) community encourages the use of Resource Description Framework with composite annotations that semantically involve ontologies to ensure completeness and accuracy. These annotations facilitate scientists to find models or detailed information to inform further reuse, such as model composition, reproduction, and curation. SPARQL has been recommended as a key standard to access semantic annotation with RDF, which helps get entities precisely. However, SPARQL is unsuitable for most repository users who explore biosimulation models freely without adequate knowledge of ontologies, RDF structure, and SPARQL syntax. We propose here a text-based information retrieval approach, CASBERT, that is easy to use and can present candidates of relevant entities from models across a repository’s contents. CASBERT adapts Bidirectional Encoder Representations from Transformers (BERT), where each composite annotation about an entity is converted into an entity embedding for subsequent storage in a list of entity embeddings. For entity lookup, a query is transformed to a query embedding and compared to the entity embeddings, and then the entities are displayed in order based on their similarity. The list structure makes it possible to implement CASBERT as an efficient search engine product, with inexpensive addition, modification, and insertion of entity embedding. To demonstrate and test CASBERT, we created a dataset for testing from the Physiome Model Repository and a static export of the BioModels database consisting of query-entities pairs. Measured using Mean Average Precision and Mean Reciprocal Rank, we found that our approach can perform better than the traditional bag-of-words method.

Published: February 2023

Optimizing the pigment volume concentration of zinc phosphate pigments can protect Al alloy 6101 from alkaline media. Additionally, zinc phosphate pigments form a shielding film on the substrate and facilitate stopping the penetration of aggressive corrosion ions. The efficiency of eco-friendly zinc phosphate pigments is almost 98% during the corrosion analysis. A comparative study of physical aging of neat epoxy and Zinc Phosphate (ZP) pigment-modified epoxy coatings on Al alloy 6101 was conducted in Xi’an, China, for one year in all four seasons, where in summer for 3 months, results degraded more due to high UV radiation and humidity; it is found that peeling force of ZP pigments modified epoxy coatings is 50% higher of than that of the neat epoxy coatings though both peel-off adhesion strength and scratch test visibility decreased in both coatings; The electrochemical resistance of ZP pigments modified epoxy coatings is about 30% higher of than that of neat epoxy coatings, the corrosion rate of ZP pigments modified epoxy coatings is about 70% lower of than that of neat epoxy coatings, moreover the gloss retention is 20% higher in the modified epoxy; Optical surface observation of the coatings showed that the ZP modified epoxy coating could effectively restrict the crack and shrinkage in coatings after aging experimentation in the natural environment.

Published: February 2023

Objectives

Non-invasive assessment of aortic hemodynamics using four dimensional (4D) flow magnetic resonance imaging (MRI) provides new information on blood flow patterns and wall shear stress (WSS). Aortic valve stenosis (AS) and/or bicuspid aortic valves (BAV) are associated with altered aortic flow patterns and elevated WSS. Aim of this study was to investigate changes in aortic hemodynamics over time in patients with AS and/or BAV with or without aortic valve replacement.

Methods

We rescheduled 20 patients for a second 4D flow MRI examination, whose first examination was at least 3 years prior. A total of 7 patients received an aortic valve replacement between baseline and follow up examination (=operated group = OP group). Aortic flow patterns (helicity/vorticity) were assessed using a semi-quantitative grading approach from 0 to 3, flow volumes were evaluated in 9 planes, WSS in 18 and peak velocity in 3 areas.

Results

While most patients had vortical and/or helical flow formations within the aorta, there was no significant change over time. Ascending aortic forward flow volumes were significantly lower in the OP group than in the NOP group at baseline (NOP 69.3 mL ± 14.2 mL vs. OP 55.3 mL ± 1.9 mL p = 0.029). WSS in the outer ascending aorta was significantly higher in the OP group than in the NOP group at baseline (NOP 0.6 ± 0.2 N/m2 vs. OP 0.8 ± 0.2 N/m2, p = 0.008). Peak velocity decreased from baseline to follow up in the aortic arch only in the OP group (1.6 ± 0.6 m/s vs. 1.2 ± 0.3 m/s, p = 0.018).

Conclusion

Aortic valve replacement influences aortic hemodynamics. The parameters improve after surgery.

Dilated Cardiomyopathy is a common form of heart failure. Determining how this disease affects the structure and organization of cardiomyocytes in the human heart is important in understanding how the heart becomes less effective at contraction. Here we isolated and characterised Affimers (small non-antibody binding proteins) to Z-disc proteins ACTN2 (α-actinin-2), ZASP (also known as LIM domain binding protein 3 or LDB3) and the N-terminal region of the giant protein titin (TTN Z1-Z2). These proteins are known to localise in both the sarcomere Z-discs and the transitional junctions, found close to the intercalated discs that connect adjacent cardiomyocytes. We use cryosections of left ventricles from two patients diagnosed with end-stage Dilated Cardiomyopathy who underwent Orthotopic Heart Transplantation and were whole genome sequenced. We describe how Affimers substantially improve the resolution achieved by confocal and STED microscopy compared to conventional antibodies. We quantified the expression of ACTN2, ZASP and TTN proteins in two patients with dilated cardiomyopathy and compared them with a sex- and age-matched healthy donor. The small size of the Affimer reagents, combined with a small linkage error (the distance from the epitope to the dye label covalently bound to the Affimer) revealed new structural details in Z-discs and intercalated discs in the failing samples. Affimers are thus useful for analysis of changes to cardiomyocyte structure and organisation in diseased hearts.

To explore the correlation between earthquakes and the pre-earthquake ionospheric shallow frequency (ELF) electric field perturbations phenomenon, the paper investigated the pre-earthquake ionospheric perturbations phenomenon, and then the Spatio-temporal evolution characteristics of the electromagnetic field before and after the global Ms ≥6.0 strong earthquakes from 2019 to 2021 were statistically analyzed. In this paper, the power spectrum data of the ELF (19.5–250 Hz) band of ionospheric electric field observed by the China Seismo-Electromagnetic Satellite (CSES) electric field detector are preclinically processed by the C-value method. A stable background field observation model was constructed using the data from 75 to 45 days before the earthquake observed by the CSES in the range of 15° above the epicenter. Then, the amplitude of the spatial electric field disturbance over the epicenter relative to the background field is extracted. Finally, the superposition analysis method statistically analyzes the spatial and temporal evolution of the spatial electric field before and after the earthquake with different characteristics. The statistical results show that the anomalies first appear in the fourth period (15–19 days before the earthquake) and the third period (10–14 days before the earthquake) and then reach the most vital and most evident during the pro-earthquake period (4 days before the earthquake and the day of the earthquake); In terms of the intensity of the anomalies caused, the magnitude seven earthquakes are stronger than the magnitude 6.0–7.0 earthquakes, and marine earthquakes are stronger than land earthquakes; in terms of the ease of observing the anomalies, the magnitude 7.0 and above are more accessible to observe than the magnitude 6.0–7.0 earthquakes, and marine earthquakes are more accessible to observe than land earthquakes.
An application of Bayesian inference to examine student retention and attrition in the STEM classroom
Authors: Bertolini Roberto , Finch Stephen J. , Nehm Ross H.
Published: February 2023

Introduction

As artificial intelligence (AI) technology becomes more widespread in the classroom environment, educators have relied on data-driven machine learning (ML) techniques and statistical frameworks to derive insights into student performance patterns. Bayesian methodologies have emerged as a more intuitive approach to frequentist methods of inference since they link prior assumptions and data together to provide a quantitative distribution of final model parameter estimates. Despite their alignment with four recent ML assessment criteria developed in the educational literature, Bayesian methodologies have received considerably less attention by academic stakeholders prompting the need to empirically discern how these techniques can be used to provide actionable insights into student performance.

Methods

To identify the factors most indicative of student retention and attrition, we apply a Bayesian framework to comparatively examine the differential impact that the amalgamation of traditional and AI-driven predictors has on student performance in an undergraduate in-person science, technology, engineering, and mathematics (STEM) course.

Results

Interaction with the course learning management system (LMS) and performance on diagnostic concept inventory (CI) assessments provided the greatest insights into final course performance. Establishing informative prior values using historical classroom data did not always appreciably enhance model fit.

Discussion

We discuss how Bayesian methodologies are a more pragmatic and interpretable way of assessing student performance and are a promising tool for use in science education research and assessment.
Multi-armed bandit based device scheduling for crowdsensing in power grids
Authors: Zhao Jie , Ni Yiyang , Zhu Huisheng
Published: February 2023

With the increase of devices in power grids, a critical challenge emerges on how to collect information from massive devices, as well as how to manage these devices. Mobile crowdsensing is a large-scale sensing paradigm empowered by ubiquitous devices and can achieve more comprehensive observation of the area of interest. However, collecting sensing data from massive devices is not easy due to the scarcity of wireless channel resources and a large amount of sensing data, as well as the different capabilities among devices. To address these challenges, device scheduling is introduced which chooses a part of mobile devices in each time slot, to collect more valuable sensing data. However, the lack of prior knowledge makes the device scheduling task hard, especially when the number of devices is huge. Thus the device scheduling problem is reformulated as a multi-armed bandit (MAB) program, one should guarantee the participation fairness of sensing devices with different coverage regions. To deal with the multi-armed bandit program, a device scheduling algorithm is proposed on the basis of the upper confidence bound policy as well as virtual queue theory. Besides, we conduct the regret analysis and prove the performance regret of the proposed algorithm with a sub-linear growth under certain conditions. Finally, simulation results verify the effectiveness of our proposed algorithm, in terms of performance regret and convergence rate.

Biochars provide several agricultural and environmental benefits, such as soil health improvement, better crop growth and yield, carbon sequestration, decreasing greenhouse gas (GHGs) emissions, and regulation of nutrient dynamics. This review highlights the role of biochar in transforming the soil’s physiochemical and biological properties, and their impact on improving seed germination and seedling growth, altering crop physiological attributes, enhancing crop resistance against biotic and abiotic stresses, improving crop productivity, curtailing GHGs, and controlling nutrient leaching losses. However, the type of feedstock used, pyrolysis temperature, application rate and method, soil type and crop species largely influence the biochar performance under different environmental conditions. Application of biochars at low rates help to promote seed germination and seedling growth. Biochar modified the abiotic and microbial processes in the rhizosphere and increased nutrient mineralization and enhanced the nutrient availability for plant uptake. Hence, biochar enhanced the plant resistance against diseases, reduced the availability of heavy metals and improved the plant resilience against environmental stressors. By providing a comprehensive analysis about the variable impacts of biochars on soil physicochemical properties, plant growth, development and productivity and mitigating environmental problems, this review is quite valuable for developing an efficient soil and crop specific biochar with desired functionalities. It could be helpful in improving crop productivity, ensuring food security and better management of environment. Furthermore, this review identifies the knowledge gaps and suggests future outlooks for the commercialization of biochar applications on large-scale.
