Decolonial thinking as an alternative to “reverse racism” in soccer
Authors: Nogueira Otávio , Steffen João Alberto , Ferreira da Silva Gilberto
Published: August 2021

This article addresses the issue of reverse racism in soccer, considered as another subjugation mechanism of the elite of white people, and the criticism of this prejudice. The main objective is to propose an alternative “other” to fight “reverse racism” in soccer, beyond academic criticism. This is a descriptive and bibliographic study, with reflections based on theoretical contributions of thinkers, mainly Latin American. As an alternative “other”, an intercultural project is proposed for the discipline of soccer in Physical Education, with emphasis on decolonial thinking, both in college and in school. It is understood that, in order to respond to the competency dimensions required for an alternative “other”, the physical education teacher must know the theoretical body that supports his field of knowledge and its connection with other areas, as well as the popular knowledge as part of thinking and doing science. We bet on the physical education professional to break the dichotomy where the place for the physical is outside the classroom and the place for the intellect is inside, and to rethink school sports as a social practice of collective participation.

Authors: SÖNMEZ TOPCU Feyza , MEN Süleyman , DURAK Merih
Published: August 2021

Magnetic Resonance Imaging has the ability to describe vessel wall thickness, plaque structure, distinguish fibrotic, fatty, calcific or hemorrhagic plaque contents with excellent soft tissue contrast. Our aim in this study is to determine symptomatic and asymptomatic carotid plaque morphology and imaging properties. We tried to understand whether plaque components in images match with histopathological sections. MRI was performed in 37 patients known to have carotid stenosis and endarterectomy decision has been taken. 24 patients were symptomatic and 13 were asymptomatic for carotid disease. A surface coil used in MRI; 5 cm of carotid segment was imaged with the carotid bifurcation in the middle. Necrotic core, fibrous cap, hemorrhage, calcification and intraluminal thrombus were determined in MR images. After surgery, the specimens were evaluated by a pathologist who was blind to the radiological findings. All plaque contents (necrotic core, hemorrhage, calcification and fibrous cap) can be imaged and separated from each-other with MRI. Necrotic core was detected in 87.9% of patients on MR images. No significant difference was found between symptomatic and asymptomatic cases in terms of the rate and dimensions of necrotic core on MRI. The presence of calcification did not show a significant difference between symptomatic and asymptomatic cases. The sensitivity of MRI in detecting in-plaque hemorrhage was calculated as 82.3% and specificity as 68.75%. The calculated rates were interpreted as MRI is significant in distinguishing cases without bleeding. Fibrous cap was more preserved in asymptomatic patients. The structure of the atheroma plaque can be imaged and distinguished from each other with MRI. The statistical results did not show the expected performance mainly due to the small number of asymptomatic cases, which was the main limitation of the study.

TRANSMISI HARGA GABAH TERHADAP HARGA BERAS: TINJAUAN ARAH, BESARAN DAN LAMA PERUBAHAN
Authors: Andiojaya Agung
Published: August 2021

Policies to maintain rice prices are a sensitive policy in Indonesia so that the government controls the rice price tightly in every level of the rice market. To make sure it runs well, the government needs to take into account the magnitude, direction, and speed of transmission of the rice price changes. When these three things can be monitored and controlled well, the success rate of controlling prices is in hand. This study investigates the direction and speed of transmission of changes in grain prices at the farm level to changes in rice prices at various levels of trade. The empirical results utilizing Granger Causality Test and VAR indicate that changes in the price of grain at the farm level significantly cause changes in rice prices at the milling and wholesale levels in a unidirectional way. Meanwhile, there is a piece of additional information where changes in the retail price of rice significantly cause changes in the price of grain at the farm level rather than vice versa. By implementing the IRFs method reveal the transmission’s duration of price change takes place in the short term and long term. Considering these findings, the policy of stabilizing rice prices at the mill and wholesale levels should be implemented immediately when the price of farmers' grain begins to change.
DAYAH AND MEUNASAH IN ACEH: REFORM IN LOCAL CONTEXT
Authors: Raya Moch. Khafidz Fuad
Published: August 2021

The history of Islamic education in the early 20th century led to various changes, especially the emergence of madrasas as an Islamic schooling system. Traditional Islamic educational institutions inevitably have to harmonise and open themselves to transformation, even though they initially experienced opposition. Using a qualitative approach with a narrative documentation method based on historical texts and observations in several Islamic educational institutions in Aceh, this article focuses on revealing the history of the dayah and meunasah as a traditional Acehnese Islamic educational institution that underwent some fundamental changes. The results found: First, the existence of the dayah is more long-term than the meunasah even though both forms of this institution are rooted in the same ideological principles with different patterns, seen from the early 20th century until implementing sharia law in Aceh after the Helsinki peace agreement, the dayah was still existed by maintaining its institutional form. Second, the emergence of madrasas as a formation of the government’s political policy on the social conditions of the people that occurred has provided space for traditional Islamic educational institutions (such as the dayah) to open themselves to including general subjects, although this second result has led to struggles; Third, there is a contestation between dayah, Islamic schools, and madrasas, with public schools driven by traditionalist and modernist groups in maintaining their existence. The contest has opened the history of the dayah and meunasah into the form of public schools and madrasas in the future, both of which apply Islamic religious material, where public schools are superior to madrasas in terms of curriculum, educational programs, and human resources.
Fibronectin: Molecular Structure, Fibrillar Structure, and Mechanochemical Signaling
Authors: Dalton Caleb J. , Lemmon Christopher A.
Published: August 2021

The extracellular matrix (ECM) plays a key role as both structural scaffold and regulator of cell signal transduction in tissues. In times of ECM assembly and turnover, cells upregulate assembly of the ECM protein, fibronectin (FN). FN is assembled by cells into viscoelastic fibrils that can bind upward of 40 distinct growth factors and cytokines. These fibrils play a key role in assembling a provisional ECM during embryonic development and wound healing. Fibril assembly is also often upregulated during disease states, including cancer and fibrotic diseases. FN fibrils have unique mechanical properties, which allow them to alter mechanotransduction signals sensed and relayed by cells. Binding of soluble growth factors to FN fibrils alters signal transduction from these proteins, while binding of other ECM proteins, including collagens, elastins, and proteoglycans, to FN fibrils facilitates the maturation and tissue specificity of the ECM. In this review, we will discuss the assembly of FN fibrils from individual FN molecules; the composition, structure, and mechanics of FN fibrils; the interaction of FN fibrils with other ECM proteins and growth factors; the role of FN in transmitting mechanobiology signaling events; and approaches for studying the mechanics of FN fibrils.
Analyzing the Contribution of Road Traffic to Changes of Air Pollutants Using Random Forest: Insights from COVID-19 lockdown in Wuhan
Authors: Wu Jiansheng , Qian Yun , Wang Yuan , Wang Na
Published: August 2021

During the COVID-19 lockdown in Wuhan, transportation, industrial production and other human activities declined significantly, as did the NO2 concentration. In order to assess the relative contributions of different factors to reductions of air pollutants, sensitivity experiments were implemented by random forest (RF) model, with the comparison of contributions of meteorology, road traffic, and emission sources between different periods. Besides, an emulator was operated to suggest an appropriate limit for control of transportation. The RF models showed different mechanisms for air pollutants. Within-city Migration index (WMI) was more important in the normal, pre-lockdown and post-pandemic model while Out-Migration Index (OMI) was emphasized in the lockdown model. In the COVID-19 lockdown period, 73.3% of the reduction can be attributed to the decreased road traffic, showing massive impact of road traffic on the air quality. In the post-pandemic period, meteorology controlled about 42.2% of the decrease and emissions from industry and household controlled 40.0% while road traffic only contributed to 17.8%. It was suggested that priority of restriction should be given to road traffic within the city. A limit of less than 40% on the control of the road traffic can get a better effect, especially for cities with severe traffic pollution.

Published: August 2021

The growth of regularly generated data from many financial activities has significant implications for every corner of financial modeling. This study has investigated the utilization of these continuous growing data by a means of an automated process. The automated process can be developed by using Machine learning based techniques that analyze the data and gain experience from the underlying data. Different important domains of financial fields such as Credit card fraud detection, bankruptcy detection, loan default prediction, investment prediction, marketing and many other financial models can be modeled by implementing machine learning models. Among several machine learning based techniques, the use of parametric and non-parametric based methods are approached by this research. Two parametric models namely Logistic Regression, Gaussian Naive Bayes models and two non-parametric methods such as Random Forest, Decision Tree are implemented in this paper. All the mentioned models are developed and implemented in the field of Credit card fraud detection, bankruptcy detection, loan default prediction. In each of the aforementioned cases, the comparative study among the classification techniques is drawn and the best model is identified. The performance of each classifier on each considered domain is evaluated by various performance metrics such as accuracy, recall, precision, F1-score and mean squared error. In the credit card fraud detection model the decision tree classifier performs the best with an accuracy of 99.1% and, in the loan default prediction and bankruptcy detection model, the random forest classifier gives the best accuracy of 97% and 96.84% respectively.
Assessing the Performance of Artificial Intelligence Systems for the Screening of Diabetic Retinopathy: A Systematic Review and Meta-Analysis
Authors: Sadjadi Ryan
Published: August 2021

Diabetic retinopathy is the most common microvascular complication of diabetes mellitus and one of the leading causes of blindness globally. Due to the progressive nature of the disease, earlier detection and timely treatment can lead to substantial reductions in the incidence of irreversible vision-loss. Artificial intelligence (AI) screening systems have offered clinically acceptable and quicker results in detecting diabetic retinopathy from retinal fundus and optical coherence tomography (OCT) images. Thus, this systematic review and meta-analysis of relevant investigations was performed to document the performance of AI screening systems that were applied to fundus and OCT images of patients from diverse geographic locations including North America, Europe, Africa, Asia, and Australia. A systematic literature search on Medline, Global Health, and PubMed was performed and studies published between October 2015 and January 2020 were included. The search strategy was based on the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines, and AI-based investigations were mandatory for studies inclusion. The abstracts, titles, and full-texts of potentially eligible studies were screened against inclusion and exclusion criteria. Twenty-one studies were included in this systematic review; 18 met inclusion criteria for the meta-analysis. The pooled sensitivity of the evaluated AI screening systems in detecting diabetic retinopathy was 0.93 (95% CI: 0.92-0.94) and the specificity was 0.88 (95% CI: 0.86-0.89). The included studies detailed training and external validation datasets, criteria for diabetic retinopathy case ascertainment, imaging modalities, DR-grading scales, and compared AI results to those of human graders (e.g., ophthalmologists, retinal specialists, trained nurses, and other healthcare providers) as a reference standard. The findings of this study showed that the majority AI screening systems demonstrated clinically acceptable levels of sensitivity and specificity for detecting referable diabetic retinopathy from retinal fundus and OCT photographs. Further improvement depends on the continual development of novel algorithms with large and gradable sets of images for training and validation. If cost-effectiveness ratios can be optimized, AI can become a financially sustainable and clinically effective intervention that can be incorporated into the healthcare systems of low-to-middle income countries (LMICs) and geographically remote locations. Combining screening technologies with treatment interventions such as anti-VEGF therapy, acellular capillary laser treatment, and vitreoretinal surgery can lead to substantial reductions in the incidence of irreversible vision-loss due to proliferative diabetic retinopathy.

Mg zonation and heterogeneity in low-Mg calcite microcrystals of a depositional chalk
Authors: Rinderknecht Chanse J. , Hasiuk Franek J. , Oborny Stephan C.
Published: August 2021

Diagenetic low-magnesium calcite (LMC) microcrystals constitute the framework that hosts most micropores in limestone reservoirs and therefore create the storage capacity for hydrocarbons, water, and anthropogenic CO2. Limestones dominated by LMC microcrystals are also commonly used for paleoclimate reconstructions and chemostratigraphic correlations. LMC microcrystals are well known to exhibit a range of textures (e.g., granular, fitted, clustered), but there exists uncertainty with regard to how these textures form. One hypothesis is that during crystal growth, Mg is incorporated into diagenetic overgrowths (cement), where the chemical zonation and microtexture may reflect diagenetic processes. To evaluate small-scale geochemical zonation in LMC microcrystals, this study uses scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS) to measure the Mg/Ca ratio across the interiors of LMC granular microcrystals from a Late Cretaceous marine chalk from the Tor Fm. (Norwegian North Sea).

Mg/Ca zonation was identified in all LMC microcrystals with a diameter > 5 μm. Generally, the cores of large crystals have lower Mg/Ca (≈ 5.9 mmol/mol) and the rims have elevated Mg/Ca (≈ 13 mmol/mol). Smaller microcrystals (< 5 μm) show no resolvable zonation, but do exhibit a wide range in Mg/Ca content from 2.9 to 32.2 mmol/mol. Measured Mg/Ca values are arbitrarily divided into three populations: low Mg (average ≈ 5.9 mmol/mol), intermediate Mg (average ≈ 13.3 mmol/mol), and high Mg (average ≈ 20 mmol/mol). The observed zonation and Mg enrichment within LMC microcrystals is interpreted to reflect depositional as well as multiple diagenetic signals, such as constructive precipitation through recrystallization and pore-filling cementation.

Although chalk from the Tor Fm. is dominated by granular euhedral LMC microcrystals, using SEM-EDS to find Mg/Ca heterogeneity in other LMC microcrystal textures may provide insight into the diagenetic processes that create textural variations in micropore-dominated limestones. The Mg data also more broadly suggest that there is useful, measurable diagenetic information in material that is otherwise considered homogeneous. Distinguishing between possible primary compositions and secondary cementation has implications for studies that rely on the primary chemistry of fine-grained carbonate deposits (e.g., micrite), such as paleoclimatology, Mg paleothermometry, and chemostratigraphy.

Published: August 2021

Yogurt was a functional drink that was high in nutritional value but had a relatively short shelf life. Roselle extract had a high content of bioactive compounds, namely anthocyanin, polypHenol, and vitamin C. The integration of yogurt with roselle extract was expected to improve product performance both from the properties of health and sensory. This study aimed to determine the effect of roselle extract addition and fermentation time on the characteristics of roselle-based yogurt products.  The research method used was an experimental method with a completely randomized design with Duncan's further test with treatments (1) the addition of rosella extract consisted of 3 levels, namely 0.5, 1.5, and 2.5 %. (2) Fermentation time: 8, 12, and 16 hours. The observed variables included chemical (pH, total titrated acid/TTA, anthocyanins), microbiology (lactic acid bacteria/LAB), and sensory.  The fermentation time affects the pH value and TAT.  The 12 hours of fermentation time gave pH and TTA values, respectively: 3.77 and 1.23%. The variation in the addition of roselle extract significantly affected the anthocyanin, TTA, and LAB values.

Financing risk is a condition of uncertainty that affects the success of a business to gain profit. Meanwhile, profitability is the ability to generate profits based on the capital owned. This study aims to analyze the risk and profitability of financing in the tapioca agro- industry using an interest-free calculation basis. The data used are primary data from field observations at the center of tapioca agro-industry in Ciluar, Bogor Regency, and secondary data from literature studies. The analysis is carried out by calculating the risk of loss and profitability of financing using the assumption of an acceptance rate of 10% of the total capital and when the level of acceptance falls -10% of the total capital owned. Furthermore, a comparison is made between tapioca agro-industries that use an interest-bearing financing scheme and an interest-free financing scheme which includes variables of risk of loss, income level, and profitability level. The research results prove that the bigger the loan used, the greater the risk to be borne. Another finding, interest-free financing in the tapioca agro- industry has a higher rate of return and income than interest-bearing financing

The white shrimp (Penaeus merguensis)is abundant in Indonesia which could be made the jerky product to increase its shelflife. This study was aimed to determine the quality and shelflife of vacuum and non- vacuum  packed white shrimp jerky stored at room temperature. And,  the packed of white shrimp jerky was stored at room temperature for 0, 3, 6 and 9 days. The data obtained were analyzed using paired sample t-test. The condition of packaging had affected the quality and storage times for this jerky. The average water content  value was 23,01% (dry basis,db) for all the treatments. For 9 days, the TVB-N (total volatile based- nitrogen) and TPC (total plate count) were 22,41% mgN/100g and 3,27 log CFU/g (vacuum packed), then 26,52 mgN/100g and 6.12 log CFU/g (non-vacuum packed), respectively. During storage,  total yeast and fungi, as well as  aw (activity water), have increased. The vacuum- packaged white shrimp jerky was the best option for storing this product, and it has a shelflife of up to 9.

Most research on the ecology of the Yellow-billed Magpie (Pica nuttalli) has been focused in oak woodlands and savannas in California’s Coast Ranges; urban and suburban populations, some of which are sizable, have received little attention. In 2020, we studied eight colonies in six parks around Sacramento and in 2021 expanded the survey to 43 sites, detecting 827 breeding magpies. Population estimates based on nest counts were generally higher than those from direct counts, and nest counts were more repeatable and efficient. Counts of recently fledged young in family groups yielded reproductive rates similar to those observed near the coast before arrival of West Nile virus in 2003, suggesting that the virus is not currently affecting nestlings’ survival. Sacramento magpies nested in the upper canopy of a wide variety of large trees, both native and non-native. They foraged preferentially in low herbaceous habitat—irrigated turf and unirrigated annual grassland that was mowed or grazed. The presence of rivers and streams influenced occupancy strongly. Colony size was strongly related to the amount of low herbaceous foraging habitat within 0.5 km of colony sites with nearby flowing water. Our results suggest that at least 4 ha of low herbaceous foraging habitat is needed to support a small nesting colony. Retention of herbaceous habitat near large trees and flowing water, plus mowing or grazing to keep herbaceous growth low, should benefit urban Yellow-billed Magpies.
Detecting Global Influence of Transcription Factor Interactions on Gene Expression in Lymphoblastoid Cells Using Neural Network Models.
Authors: Patel Neel , Bush William S.
Published: August 2021

Background Transcription factor(TF) interactions are known to regulate gene expression in eukaryotes via TF regulatory modules(TRMs). Such interactions can be formed due to co-localizing TFs binding proximally to each other in the DNA sequence or between distally binding TFs via long distance chromatin looping. While the former type of interaction has been characterized extensively, long distance TF interactions are still largely understudied. Furthermore, most prior approaches have focused on characterizing physical TF interactions without accounting for their effects on gene expression regulation. Understanding how TRMs influence gene expression regulation could aid in identifying diseases caused by disruptions to these mechanisms. In this paper, we present a novel neural network based approach to detect TRM in the GM12878 immortalized lymphoblastoid cell line. Results We estimated main effects of 149 individual TFs and interaction effects of 48 distinct combinations of TFs for their influence on gene expression based on the neural networks trained to predict gene expression using multi-omics TF regulatory features. We identified several well-known TF interactions and discovered multiple previously uncharacterized TF interactions within our detected set of TRMs. We further characterized the pairwise TF interactions using long distance chromatin looping and motif co-occurrence data. We found that nearly all the TFs constituting TRMs detected by our approach interacted via chromatin looping, and that these TFs further interact with promoters to influence gene expression through one of four possible regulatory configurations.Conclusion We have detected TRMs using neural network models based on regulatory features. We have also described these TRMs based on their regulatory potential along with presenting evidence for the possibility of TF interactions forming the TRMs occurring via chromatin looping.

Background: Tracheostomy is one of the more commonly performed procedures in critically ill patients. Postoperative scarring is one of the bothersome sequelae of tracheostomies. Scars distorted the physical appearance, especially when found on the head and neck, which could cause a negative impact on quality of life. The aim of this study was to evaluate and assess the impact on quality of life of post-tracheostomy`s scars, depending on the method of tracheostomy.Methods: The prospective, single-center observational case-control study was conducted. One hundred and fifty-six persons with more than four months of post-tracheostomy surgical scars presence were observed using the Patient and Observer Scar Assessment Scale and Dermatology Life Quality index questionnaire. Persons were divided on two groups depending on method of performed tracheostomy, and duration of cannulated period was considered in both groups. Statistical analyses were performed by using SPSS ver. 16.0 (SPSS Inc., Chicago, IL, USA) and p-values of <0.05 were considered significant.Results: The patients who had a tracheostomic tube cannulation period of less than 15 days had better cosmetic results than those who had tracheostomic tubes for more than 15 days, regardless of the method of tracheostomy 6.64± 0.082 vs. 16.15± 0.096 (p<0.001) in surgical tracheostomy group and 7.26± 0.211 vs.14.17± 0.379 (p<0.05) in percutaneous dilatational group. The Dermatology Life Quality index scores have shown a mean value of 0.6 ±0.01, which means that post-tracheostomy scarring in the presented study, had no effect on the person's quality of life.Conclusions: Aesthetic outcomes of post-tracheostomy`s scars after the open surgical tracheostomy technique, performed using a minimally invasive approach, did not statistically differ from those of the percutaneous dilatational technique. Persons with a long duration of tracheostomic tube ventilation showed worse aesthetic outcomes compared with short-term tracheostomic cannulation, not dependent on the tracheostomy performing technique.The Dermatology Life Quality index have shown that post-tracheostomy`s scarring in the presented study had no effect on the person's quality of life.Trial registration: ISRCTN24668317 (IRB no.YSMU №7/18-19).

Published: August 2021

Enydra fluctuans DC. (Asteraceae) is an edible semi-aquatic floating or trailing herbaceous plant widely distributed in tropical Africa, South and South East Asia, and Australia. Its leaves, which are consumed as a vegetable, are also used in traditional medicine to treat several diseases. The efficacy of this plant in removal of copper and lead from aqueous medium was tested in the present study. Accumulation of both Cu and Pb was significantly higher in root than that in leaf and stem. Though all the bioconcentration factor (BCF) values were greater than unity, none of the translocation factor (TF) values was greater than unity, indicating that this plant could not be considered a hyperaccumulator of these metals. Nevertheless, E. fluctuans could remove Cu from aqueous medium at rates ranging from 98.8–99.7 %, with a mean reduction of 99.2 % after 96 h exposure at various concentrations. The removal of Pb ranged from 97.1–99.1 %, with a mean reduction of 98.2 %. Thus, E. fluctuans showed high potential in removal of Cu and Pb from aqueous medium, and has the prospect of being used in phytoremediation of these metals.
