Authors: Lv Panpan , Cao Zhen , Zhu Zhengqi , Xu Xiaoqin , Zhao Zhen
Published: September 2024

Background

The efficacy of artificial neural network (ANN) models employing laboratory variables for predicting fatty liver disease (FLD) remains inadequately established. The study aimed to develop ANN models to precisely predict FLD.

Methods

Of 12,058 participants undergoing the initial FLD screening, 7,990 eligible participants were included. A total of 6,309 participants were divided randomly into the training (4,415 participants, 70%) and validation (1,894 participants, 30%) sets for developing prediction models. The performance of ANNs was additionally tested in the testing set (1,681 participants). The area under the receiver operating characteristic curve (AUROC) was employed to assess the models’ performance.

Results

The 18-variable, 11-variable, 3-variable, and 2-variable models each achieved robust FLD prediction performance, with AUROCs over 0.92, 0.91, and 0.89 in the training, validation, and testing, respectively. Although slightly inferior to the other three models in performance (AUROC ranges: 0.89–0.92 vs 0.91–0.95), the 2-variable model showed 80.3% accuracy and 89.7% positive predictive value in the testing. Incorporating age and gender increased the AUROCs of the resulting 20-variable, 13-variable, 5-variable, and 4-variable models each to over 0.93, 0.92, and 0.91 in the training, validation, and testing, respectively.

Conclusions

Implementation of the ANN models could effectively predict FLD, with enhanced predictive performance via the inclusion of age and gender.

Authors: Akalonu Chinwendu Praise
Published: September 2024

Purpose

This study seeks to understand the relationship between a country's political system and its content removal request to Google. It also investigates the trends in content removal requests to Google over 11 years (2011–2021).

Design

The study uses secondary data derived from 2020 Google Transparency Report and Freedom House Report with information from 89 countries and three Google products – YouTube, Web search, and Blogger.

Findings

Countries with lower freedom scores (categorized as authoritarian) showed overall higher content removal requests as well as higher requests using reasons like national security and government criticism. Countries with higher freedom scores (categorized as libertarian) requested for more content removal using defamation. Results also show an increase in overall content removal overtime from 2011 to 2021.

Practical Implications

This study adds empirical evidence to the discourse on freedom of speech across countries. It also demonstrates the viability of online secondary data sources for empirical research purposes. It has implications for understanding global content moderation and its relationship with freedom of expression.

Social Implications

The study demonstrates the need to address the global decline in democracy across countries (both authoritarian and libertarian countries).

Originality Value

The study is one of the first to use Google’s Transparency report for post-publication censorship/ content moderation analysis.

MEMORABLE LITERARY ALMANACS AS A GENRE OF THE 80S OF THE 19TH CENTURY
Authors: Isachenko Tatiana
Published: September 2024

The article analyzes the significance of the commemorative literary grand ducal almanacs of the 1880s in modern humanitarian scientific knowledge. The literary almanac of the 1880s is considered as a special type of almanac, shedding light on the evolution of the genre and the literary tastes of the House of Romanov. The albums stored in the specialized departments of Russia`s largest libraries once belonged to the personal collections of “Their Imperial Majesty`s Own Libraries” in the Winter, Anichkov, Gatchina, Vladimir, Marble, Strelna and other imperial palaces. After the coup d`etat of 1917, they were merged with the collections of the RSL, the RNB, and the Pushkin House. Today, these books are of considerable interest in terms of their genre originality and role in the evolution of the almanac. Important evolution-related typological features that disrupt the established patterns are highlighted. This applies, first and foremost, to the correlation of the type of publication itself and the poetics of texts. The logic of the functioning of the calendar collection (calendar, “pocket book”, literary commemorative album) chronologically covers an extremely wide time range from the end of the Middle Ages to the beginning of the 20th century. The date sequence (the sequence of the annual circle) correlates with the filling principles. The timing of the analyzed texts can be traced to certain events. In this particular case, they are traced to the events in the life of the Imperial family. The calendar principle of publication structure sets an appropriate rhythm in the albums, where the pages, according to the epigraph (1885 ed.), are “filled with the memory of the heart.” In the aggregate of data, each extant instance is a complex compositional system of multilevel interpretation (“multilevel artifact”).

Published: September 2024

Of the two species of the genus Robinia L., which are native to North America and introduced in Polesie, Black Locust (Robinia pseudoacacia L.) is traditionally used as a medicinal, technical and food plant. One of the least covered aspects of using Black Locust is making jam from the flowers of this plant. The aim of our study is to report the modern Black Locust use to make jam by local residents of Polesie. Sociological survey of the 250 adult local inhabitants on the use of Robinia pseudoacacia was conducted. The Black Locust syrup in Polesie is used as an effective antispasmodic, expectorant, diuretic, choleretic, sedative, hemostatic, antipyretic, laxative, hypotensive, anti-inflammatory and healing agent. The Black Locust flowers is perfect as an antipyretic, and also for the prevention of diseases of the lungs and bronchi, and also as an effective antispasmodic, that is, for spasms of internal organs or muscles. The article presents recipes of the Polesie local residents for making the Black Locust flowers jams, namely: Black Locust jam with apple juice, Black Locust jam with grape juice, Black Locust jam with honey, transparent Black Locust jam with white wine. Black Locust jams are not only tasty national products, but also have beneficial properties for human health. The claims of the Polesie local residents about the Black Locust flower products antibacterial action are not unfounded: scientific publications provide facts about the bactericidal effect of Robinia pseudoacacia flower extracts. The conducted research encourages further research into the properties of Black Locust as a potential raw material for use in the production of food products, as well as cosmetology and medical use.

Medical Home Care for Children with Deafness and Hearing Problems
Authors: Khalsa Inderpreet Kaur , Chan Dylan K.
Published: September 2024

BACKGROUND AND OBJECTIVES

Since 2001, the American Academy of Pediatrics (AAP) has advocated for improving the effectiveness of early hearing screening, diagnosis, and intervention (EHDI) and reducing hearing health disparities through the medical home model of care (MHMOC). However, the scope of the MHMOC and its components and potential disparities among US children with deafness or hearing problems (DHH) have not been identified.

METHODS

Data from the 2016 to 2020 National Survey of Children’s Health (N = 174 551) were analyzed, including 12 121 children with DHH, 171 523 children without DHH, and 38 722 with other special health needs (SHCN). Univariable statistics and multivariable logistic regression were used to analyze the association of hearing problems with medical home composite and components and cohort disparities.

RESULTS

After adjusting for sociodemographic characteristics, medical home care was less likely for children with DHH (adjusted odds ratio: 0.74; 95% confidence interval: 0.56–0.97) compared with children without DHH. Children with DHH and SHCN were also less likely to receive medical home care compared with other SHCN children (adjusted odds ratio: 0.71; 95% confidence interval: 0.55–0.92). Specific medical home components significantly less prevalent among children with DHH included family-centered care, ease of referrals, and effective care coordination, whereas a usual source for sick care was more prevalent, although not statistically significant.

CONCLUSIONS

Despite over two decades of efforts to improve EHDI through the medical home, rates of the MHMOC for children with DHH remain disparately low. Systems-level quality improvement efforts supporting the medical home will be necessary to allow the MHMOC to support early hearing detection and intervention (EHDI) systems.

Published: September 2024

The objective of the study was to identify and compare differences in the attitudes of non-disabled students towards the inclusion of a peer with a visual impairment in physical and sport education (PSE) classes. The research sample comprised a total of 419 primary school students of the 6th grade (n = 96; 11.7 ± 0.54 years) 7th grade (n = 120; 12.7 ± 0.57 years), 8th grade (n = 109; 13.7 ± 0.55 years), and 9th grade (n = 94; 14.6 ± 0.52 years) level. A modified version of a CAIPE-R was used as a primary research method. Students of the 6th, 7th and 8th grades have more positive attitudes towards the inclusion of a peer with visual impairment in PSE lessons compared to the 9th grade students in social interactions area as well as in rules modifications area. The 6th, 7th, and 8th grades student groups showed significantly more positive social interaction attitudes compared to sport-specific attitudes. No significant differences were found between social interactions and sport-specific attitudes in the group of the 9th grade primary school students. Regarding the most appropriate solutions for the inclusion of students with visual impairment in PSE lessons, more information on attitudes towards inclusion is also needed from teachers and school management.

Alone among the peoples of northern Europe, Scots historically have harboured an aversion to pork. The cause, extent and even existence of the aversion, at times ascending to phobia, have been subject to a certain amount of debate for over a century. The degree and scope of the aversion varied across time and space but existed well into the twentieth century. Neither economic nor ecological considerations can explain the phenomenon, which arises from cultural conditions peculiar to Scotland.

Published: September 2024

The comparative analysis of predictive methodologies highlights the original contribution of this study in optimizing the prediction of Rate of Penetration (ROP) in mining drilling operations. The emphasis on employing advanced Artificial Neural Networks (ANN), fuzzy logic, and linear regression models provides new insights into enhancing predictive accuracy and operational efficiency in mining practices. This study aims to quantify the effects of three pivotal drilling parameters: compressive strength, rotational pressure, and thrust pressure on the rate of penetration, a critical performance metric in mining drilling operations. Additionally, the study seeks to develop and evaluate advanced predictive methodologies for predicting ROP. The effects of compressive strength, rotational pressure, and thrust pressure on the rate of penetration were investigated through a Design of Experiments (DOE) approach. Initially, the main effects and two-way interactions among these variables were identified using DOE. Subsequently, three predictive methodologies: linear regression, fuzzy logic, and artificial neural networks, were developed and evaluated to predict ROP based on the identified factors. The evaluation of predictive methodologies revealed that the ANN model demonstrated superior accuracy in predicting the ROP, achieving over 95 % accuracy. Additionally, the fuzzy logic model provided effective handling of nonlinearities in the data, while the linear regression model offered initial insights into the relationships between the variables. The application of advanced predictive methodologies: artificial neural networks, fuzzy logic, and linear regression to optimize the prediction of rate of penetration in mining drilling operations offers precise insights into drilling parameter interactions, enhancing operational efficiency and supporting informed decision making in mining practices.
Evaluating technology capability in strategy implementation and firm performance of the furniture manufacturing sector in Kenya
Authors: Were Jane Nasimiyu
Published: September 2024

The object of the study is the performance of the furniture manufacturing sector in Kenya. The paper utilized descriptive and explanatory research design. The study targeted a population of 686 managerial staff and 195 CEOs in the furniture manufacturing sector. Structured questionnaires were distributed to the senior managers and a factor analysis was used to reduce the number of variables and establish the underlying constructs while analysis of moments of structures was applied to develop the theory.
Technology capability was found to explain 49 % of the variance in the firm performance. The fit indices suggested that the data was an adequate fit of the hypothesized model relating to technology capability and firm performance NFI=0.604, RFI=0.501, IFI=0.639, TLI=0.539 and CFI=0.634 with a p-value>0.05. In addition, the study found out that technology capability and firm performance had a positive and statistically significant contribution at 0.05 level of significance. This was depicted by the significance of the standardized regression coefficient of technology capability hypothesized path (β=0.878, S.E.=0.75, C.R.=11.743, and p-value<0.05). The findings also revealed that the size and age of the firm do not moderate technology capability in strategy implementation on firm performance. This was depicted by the significance of the standardized regression coefficient of firm size and firm age hypothesized path (β=-0.171, S.E.=2.015, C.R.=-0.085 and p-value>0.05). Therefore, the alternative hypothesis that size and age have a negative moderating contribution on firm performance was rejected at 0.05 level of significance.
To enhance a firm's performance in terms of profitability and growth, it is crucial to manage and sustain technology capabilities through an effective strategy implementation process. The study not only adds value to the existing body of knowledge in strategic management practice but points out that when implementing strategy, CEOs and senior managers should consider technology capability factors to improve the firm performance.
Determination of the influence of the surplus construction on the parameters of the shrinkage shells in the «Body»-type steel castings when casting in single sand molds

Published: September 2024

The object of research is the technology of manufacturing «Body»-type shaped castings of the from medium carbon steel in one-time sand molds.
The existing problem is that the design of the casting and foundry equipment significantly affect the formation of internal defects in castings. This especially applies to steel castings, the technology of which is more complicated than the technology of cast iron castings due to much worse casting properties of steel.
To determine the influence of the location of surpluses on the «Body»-type steel castings of the on the formation of shrinkage shells, computer modeling was used, in the process of which 5 computer experiments were conducted with different sizes and geometries of surpluses.
According to the simulation results, it was found that with some technological options, there is a risk of the shrinkage shell penetrating into the casting body. The use of a cylindrical surplus of a rectangular cross-section with fillets ensures complete absorption of the shrink shell in the place of surplus installation. Using an excess round section at the installation location does not guarantee absorption of the shrink shell. The determining factor affecting the coefficient of increase in the depth of the shrinking shell is the excess volume. This influence can be described by a functional dependence of the logarithmic type with the coefficient of determination R2=0.82.
It was determined that the ratio of the diameter of the inlet to its height does not affect the coefficient of increase in the depth of the shrinking shell. The resulting functional dependence allows to set the excess volume that provides a minimum growth factor while simultaneously preventing excess metal consumption.
The presented study will be useful for machine-building enterprises that have foundries in their structure, where shaped castings are made in one-time sand molds.
Development of the stick-slip friction model for discrete elements modeling
Authors: Khellaf Abdelghani , Mansouri Mouloud
Published: September 2024

The object of the research is an intergranular friction model for use in discrete-element modeling of the mechanical behavior of granular materials under static and dynamic conditions. As in this approach grains are modeled by independent elements interacting through contact forces, the selection of contact force models, and in particular for the tangential component (friction), represents the most important task in obtaining the most realistic macroscopic behavior. There are many friction models that work well in dynamic regimes, but fail to model mechanical behavior in static or quasi-static regimes. In this work, an intergranular friction model is proposed based on Coulomb's regularized friction model, which takes into account the stick-slip phenomenon that appears at low sliding speeds at the contact. Three different examples are designed and modeled in order to demonstrate the robustness of the model in different situations including static, quasi-static and dynamic regimes. The first is a basic example consisting of the translational motion of a grain on a planar surface with a relatively low constant velocity. This example allowed to capture the stick-slip phenomenon. The second represents a grain subjected to its own weight and supported essentially by frictional forces. This example shows that the model works well in both quasi-static and static regimes. The third example consists of a grain sliding on a plate and subjected to accelerated motion. It showed the effect of friction velocity on the occurrence of stick-slip, as well as the evolution of friction force with sliding velocity. The obtained results demonstrated that the model effectively captures shear behavior in the different regimes. It could therefore be used in discrete element modeling of granular materials under both static and dynamic conditions. As in this work, the model is formulated in 2D, it would be interesting to develop a general 3D formulation so that it can be easily applied in 3D modeling.
Determination of the density of the surface which is exposed to various working bodies of the vibration plate VP-10
Authors: Yakovenko Andrii , Vasyliev Oleksii
Published: September 2024

The object of research is a vibrating plate with interchangeable working bodies developed by the authors. Vibrating plates are an integral part of small mechanization equipment and are mainly intended for layer-by-layer compaction of various materials, such as sand, gravel, bituminous mixtures, etc. Vibration compaction methods are widely used in the construction of road surfaces and other infrastructure facilities. Self-propelled vibrating slabs are also used effectively in other construction processes such as compaction, trench reinforcement, land work and laying paving slabs. They ensure effective compaction of materials due to vibration.
This paper is aimed at determining the optimal equipment for compaction of materials during the construction of small objects. Analyzing the characteristics of the machines that most affect the quality of compaction, it is also necessary to evaluate their influence in specific conditions. Studies show that for each type of material, a special working body should be selected, taking into account the specific conditions and requirements for compaction, to ensure optimal quality of work.
The authors seek to consider the selection of vibrating plates and their working bodies that best meet the requirements and needs of compaction of various materials on limited construction sites. The analysis of different types of working bodies for different surfaces helps to improve the compaction process and provides optimal conditions for different types of building materials, taking into account their unique properties.
The paper examines the influence of the working body on the processed environment, in particular, analyzes the ability of various factors to influence the quality of material compaction. Special attention is paid to the influence of the geometry and size of the contact area on the sealing efficiency of each material type. Overall, this analysis can significantly improve material compaction strategies in the construction industry, contributing to improved construction quality.

Abstract Healthy fish populations lead to healthy aquatic ecosystems and it is our responsibility to be a part of the solution. Fish is one of the most favored foods and is suitable for people of all ages. Fish is an essential source of protein, vitamins, and minerals and a source of income for millions of people. Human population growth and climate change are putting a strain on our food system, demanding the development of sustainable services to enhance global food production and its security. Food safety is an intricate problem in both developed and developing countries. Fresh fish is a highly perishable food with a limited life span; as a result, it must be delivered and kept carefully to minimize deterioration and assure safety. Fish spoilage is linked to biochemical changes that occur post-harvest, such as storage and transportation. These modifications can account for fish spoilage by altering the taste, texture, and appearance. Fish harvesting, distribution, and post-harvest handling are all unhygienic, resulting in poor and unpredictable fish quality in the market. Many innovative and effective control measurements of various bacteria in fish have been proposed and evaluated. This review is a systematic approach to investigating post-harvest fish spoilage, its assessment, and control strategies.
Assessment of fatty acid composition and amino acid profiles of three important fresh water fish species native to river Indus Pakistan

Published: September 2024

Abstract This study was carried out to analyze the fatty acid and amino acid compositions of three economically important freshwater fish species, Mali (Wallago attu), Raho (Labeo rohita), and Mahseer (Tor putitora), indigenous to Indus River, Pakistan.. Amino acid profiling was done by high-performance liquid chromatography (HPLC) while gas chromatography (GC) was used for fatty acid analysis. Glutamic acid, aspartic acid, arginine, alanine, leucine, lysine and isoleucine were the most predominant amino acid while palmitic acid (C16:0), oleic acid (C18:1c), palmitoliec acid (C16:1c), linolenic acids (C18:2c) and docosahexaenoic acids (DHA C22:6) were the notable fatty acids present in these species. Our results indicated that all species have comparable nutritional composition and are good source of healthy human diet. Our findings will help the people to make informed choice while selecting fish for consumption and will pave the way for future researchers in planning new strategies to enhance the growth and production of commercial fish species. It will also be helpful for theFrom the current finding it was concluded that all fish species under discussion are rich in amino acids and fatty acids. These species contain essential amino acids and important fatty acid such as omega3 and omega 6, thus raising the nutritional quality of these species.
Comparações, sínteses e extensões: a jurisprudência do Superior Tribunal de Justiça como metadados digitais
Authors: Munhoz Sara R.
Published: September 2024

Resumo Este artigo contribui para os debates acerca dos conceitos de acesso e de democratização do sistema de justiça por meio da atenção a circuitos técnico-burocráticos ainda pouco inspecionados pela antropologia interessada no direito: os que, depois de promulgadas as sentenças, se encarregam de sua organização e divulgação em ferramentas de busca digitais. Pelo exame de documentos institucionais do Superior Tribunal de Justiça (STJ), descrevo a jurisprudência não como o resultado direto dos julgamentos de tribunais superiores, mas como o produto de um complexo trabalho técnico-documental, realizado por analistas humanos e aplicativos computacionais, que recorre a comparações, sínteses e extensões de documentos abrigados em uma volumosa base de dados. Demonstro como a gestão desta base e a confecção de “representações digitais” das sentenças promulgadas intrincam-se ao conceito de uniformização, central às atividades do Tribunal. Argumento, enfim, que o apelo democrático do STJ, a despeito das numerosas cancelas que cerceiam suas entradas, ancora-se contemporaneamente na disponibilização cuidadosa de seus enunciados a todos os usuários que tenham acesso à internet.
Mapa, Território e Tudo o que há no Meio: dados ambientais e territorialização
Authors: Walford Tone
Published: September 2024

Resumo Este artigo argumenta que, a fim de lidar com formas emergentes de governança e de política ambiental, as alegações desespacializadas e não situadas das iniciativas de dados abertos (open data) precisam ser interrogadas. Com base em uma etnografia com um projeto científico internacional na Amazônia brasileira, o artigo explora a coleta cotidiana de dados ambientais em campo como uma forma de criação do espaço, por meio de processos simultâneos de reterritorialização e desterritorialização. O artigo traz à luz o trabalho contínuo e as complexas estratificações e dobragens destas formações territoriais, bem como suas capacidades de fomentar mundos sociais e afetivos ambivalentemente diferenciados. Embora estes mundos emerjam de tecnologias de territorialização, eles não são totalmente definidos por elas. A seguir, o artigo aborda um caso contrastante de infraestruturas de dados e portais aparentemente virtuais em iniciativas de dados abertos, questionando que formas de territorialização eles poderão constituir. Ao final, apresenta a sugestão provisória de que a “abertura” não é uma forma espacial que o mundo supostamente assume, mas o próprio aparato de extensão, a maquinaria social e política de desterritorialização e reterritorialização.
O caminho da pluralidade: alternativas e possibilidades nas ciências sociais
Authors: Soares Joice de Souza
Published: September 2024

Resumo Nas ciências sociais, alguns autores destacaram-se em suas tentativas interpretativas acerca da realidade social, tornando-se referências para pesquisas em várias áreas do conhecimento. A despeito de divergências teóricas, tais autores possuíam algumas características comuns: todos homens, brancos, oriundos de países europeus – quando muito, nascidos na América do Norte. Todavia, os esforços para entender as relações sociais não se restringiram à produção daqueles que se notabilizaram e aos quais fora concedido grande prestígio. Em diferentes disciplinas, as últimas décadas têm sido marcadas pela descoberta, emergência e visibilidade de possibilidades distintas daquelas estabelecidas no modelo hegemônico de intelectualidade moderna ocidental. Em se tratando das ciências sociais, o sociólogo e antropólogo Celso Castro publicou, em 2022, uma obra que caminha nessa mesma direção. Além do cânone: para ampliar e diversificar as ciências sociais demonstra que as abordagens consagradas não são as únicas possibilidades existentes. No livro, Castro apresenta ao público leitor uma seleção de cientistas sociais que, a partir de diferentes territórios, buscaram compreender a sociedade – as sociedades, aliás – com formas originais para explicá-las. A coletânea traz ao Brasil textos inéditos, excertos das obras produzidas pelas dezesseis autoras e autores selecionados. O principal objetivo da obra é despertar o interesse e a curiosidade de pesquisadoras e pesquisadores brasileiros sobre possibilidades novas e plurais para interpretar os fenômenos sociais. Neste texto, busca-se evidenciar o empenho de Castro, alinhando-o ao movimento amplo em direção à superação da razão moderna como única alternativa para a compreensão das sociedades.
Assistência ao trabalho de parto e parto de mulheres privadas de liberdade: revisão de escopo

RESUMO Objetivo: Mapear e analisar as evidências científicas sobre a assistência prestada a mulheres privadas de liberdade durante o trabalho de parto e parto. Método: Revisão de escopo, desenvolvida em conformidade com o método JBI, cujas fontes de informação foram acessadas em bases de dados e na literatura cinzenta. A seleção foi realizada entre outubro e dezembro de 2023, a partir da leitura dos títulos, resumos e descritores, considerando os seguintes critérios de elegibilidade: artigos, dissertações e teses com diferentes desenhos metodológicos disponíveis na íntegra, sem delimitação de idioma e tempo. A análise foi conduzida por dois revisores independentes, utilizando-se a análise de conteúdo indutiva. Resultados: Foram incluídos 15 estudos. A partir da síntese dos resultados, emergiram duas categorias: Da cela para a sala de parto: assistência de mulheres privadas de liberdade; Experiências de mulheres privadas de liberdade durante o trabalho de parto e parto. Conclusão: Este estudo aponta a fragilidade das práticas assistenciais durante o trabalho de parto e parto, impondo desafios significativos e resultando em experiências adversas que comprometem a qualidade da maternidade e violam os direitos fundamentais das mulheres.
