Maternal and fetal outcomes among pregnant women with endometriosis
Authors: Abdessamie Sara , Czuzoj-Shulman Nicholas , Abenhaim Haim Arie
Published: November 2024

Objectives

Endometriosis, a condition in which endometrial-like tissue grows outside of the uterus, is a common disorder among women of reproductive-age. The objective of the study is to examine the associations between endometriosis in pregnancy and adverse maternal and newborn events.

Methods

Data from the 1999–2019 Healthcare Cost and Utilization Project, Nationwide Inpatient Sample, which is from the United States, were used to perform a retrospective cohort study. Associations between endometriosis and maternal and newborn outcomes were examined using multivariate logistic regression models adjusted for baseline maternal characteristics.

Results

We identified 14,956 individuals with endometriosis and 16,911,497 individuals without endometriosis. The prevalence of endometriosis in pregnancy rose substantially from 34.9 to 160.6 per 100,000 births between 1999 and 2019. Individuals with endometriosis were more likely older in age, of Caucasian ethnicity, belonged to higher income quartiles, had private insurance, smoked, and were obese. Endometriosis in pregnancy was associated with greater odds of pre-eclampsia, gestational diabetes, placenta previa, placental abruption, preterm birth, chorioamnionitis, and postpartum hemorrhage. Growth restriction and congenital anomalies were more frequent among newborns born to individuals with endometriosis.

Conclusions

Endometriosis in pregnancy renders individuals and their newborns at greater risk for poor outcomes in pregnancy. Hence, it is prudent for obstetrical care providers to be aware of the adverse events associated with endometriosis and to closely follow the pregnancies of women with this condition.
Petrification in Contemporary Set Theory: The Multiverse and the Later Wittgenstein
Authors: Pérez-Escobar José Antonio , Rittberg Colin Jakob , Sarikaya Deniz
Published: November 2024

This paper has two aims. First, we argue that Wittgenstein’s notion of petrification can be used to explain phenomena in advanced mathematics, sometimes better than more popular views on mathematics, such as formalism, even though petrification usually suffers from a diet of examples of a very basic nature (in particular a focus on addition of small numbers). Second, we analyse current disagreements on the absolute undecidability of CH under the notion of petrification and hinge epistemology. We argue that in contemporary set theory the usage of construction techniques for set-theoretic models in which the Continuum Hypothesis holds and those in which it fails have petrified into the normative demand that CH remain undecidable. That is, the continuous and successful practices involving the construction of various set-theoretic models now act as a normative hinge shared among practitioners, i.e., have normative force in the discipline. However, not all hinges are universal, which is why we find disagreements in set theory. We will show that this is a refinement of, and partially conflicts with, the arguments presented by set theorist Joel David Hamkins.
Die Verbreitung antisemitischer Ressentiments unter Jugendlichen und Heranwachsenden in Deutschland: Zusammenhänge mit Migration und Religion
Authors: Fischer Jannik M. K. , Wetzels Peter
Published: November 2024

Es werden Ergebnisse einer von März bis Mai 2022 durchgeführten Online-Befragung einer bundesweit repräsentativen Einwohnermeldeamtsstichprobe von N = 3.270 jungen Menschen im Alter von 16 bis 21 Jahren zur Verbreitung und sozialen Verteilung klassischer Formen antisemitischer Einstellungen unter Jugendlichen und Heranwachsenden in Deutschland vorgestellt. 2.1 % der jungen Personen sind danach offen für antisemitische Ressentiments und weitere 2.0 % lassen eindeutig antisemitische Einstellungen erkennen. Damit sind die Prävalenzraten antisemitischer Einstellungen in Bezug auf die Gesamtpopulation der jungen Menschen nur etwa halb so hoch wie dies bei Erwachsenen in demselben Jahr mit den gleichen Messinstrumenten festgestellt werden konnte. Es sind allerdings erhebliche Differenzen für nach Migrationshintergrund und Religionszugehörigkeit bestimmte Teilgruppen zu erkennen. Personen mit Migrationshintergrund weisen signifikant erhöhte Raten antisemitischer Einstellungen auf. Besonders stark ausgeprägt ist das bei jungen Muslim:innen. Multivariate Analysen zeigen weiter, dass die hohe Verbreitung antisemitischer Ressentiments bei jungen Muslim:innen nicht auf deren ebenfalls nachweisbar erhöhten Belastungen durch individuelle Diskriminierungserfahrungen oder die Wahrnehmung einer kollektiven Marginalisierung ihrer Eigengruppe zurückzuführen ist. Wichtige Einflussfaktoren sind, neben geringer Bildung, vor allem eine Neigung zum Verschwörungsglauben sowie eine rigide, fundamentalistische Religionsauffassung. Eine hohe individuelle Religiosität und Gläubigkeit sind hingegen multivariat nicht bedeutsam. Auffallend ist die ganz erhebliche Überrepräsentation von Muslim:innen der ersten Migrantengeneration unter den antisemitisch eingestellten jungen Menschen. Die vorgelegten Befunde haben politische wie auch praktische Implikationen für die Antisemitismusprävention. Sie zeigen, dass die zu erreichende Zielgruppe für Antisemitismusprävention unter jungen Menschen zu erheblichen Teilen aus neu zugewanderten muslimischen Migrant:innen besteht.

Objectives

The 13-item pain catastrophizing scale (PCS) is the most commonly used measure of pain catastrophizing. A validated Finnish version of the PCS has previously been unavailable. The objectives were to translate the original English version of the PCS into Finnish (PCS-FI), then to evaluate (i) structural validity of the PCS-FI with a confirmatory factor analysis (CFA), (ii) internal reliability with Cronbach’s alpha, Omega, and Omega hierarchical, (iii) convergent validity with measures of well-being, quality of life, sleep quality, symptoms of central sensitization, and anxiety, and (iv) known-groups validity between participants with chronic low back pain (CLBP) and pain-free controls.

Methods

The translation process was performed with established guidelines. The PCS-FI was psychometrically validated using 92 participants with CLBP and 53 pain-free controls.

Results

Structural validity with CFA supported a bifactor solution. However, low reliability was found for the three specific factors (ω
h ranging from 0.14 to 0.18) compared to the general factor (ω
h = 0.88) suggesting that only the total score should be used. Convergent validity analysis showed satisfactory correlations and medium effect sizes with the other patient-reported outcome measures. Participants with CLBP had significantly higher total PCS-FI scores than pain-free controls.

Conclusions

The PCS-FI appears to be a valid and reliable instrument for assessing pain-related catastrophizing in Finnish-speaking populations. Ethical approval for this study was obtained from the Research Ethics Committee of the Northern Savo Hospital District, identification number 2131/2022, on the 31st of January 2022.

Authors: Lauber Dominique M.
Published: November 2024

Bei Bürgergeldbeziehenden mit Suchtverhalten liegen häufig komplexe Problemlagen vor, deren Bearbeitung sich über verschiedene Rechtskreise und Zuständigkeiten von Trägern des sozialen Hilfesystems erstreckt. Gleichzeitig ist im Rahmen der Beratung der Jobcenter eine umfangreiche Problembearbeitung nicht möglich. Im Rahmen des Bundesprogramms „Innovative Wege zur Teilhabe am Arbeitsleben – rehapro“ wird deshalb in einem Modellprojekt ein Case Management-Ansatz für diese Adressat*innengruppe erprobt. Dieser beinhaltet die Zusammenarbeit des Jobcenters und weiterer freier Träger von sozialen Hilfen vor Ort in einem Netzwerk und multiperspektivische Fallarbeit durch Case Manager*innen. Ziel ist dabei die durchgehende Versorgung mit individualisierten Hilfen sowie die Verbesserung der sozialen Teilhabe und der Erwerbsfähigkeit. Im Beitrag werden Ergebnisse der Evaluation des Modellprojekts vorgestellt, bei der der (Nicht-)Nutzen der Teilnahme aus Sicht der Nutzer*innen des Projekts erhoben wurde.
Self-Awareness from Whole-Body Movements
Authors: Kadambi Akila , Erlikhman Gennady , Johnson Micah , Monti Martin M. , Iacoboni Marco , Lu Hongjing
Published: November 2024

Humans can recognize their whole-body movements even when displayed as dynamic dot patterns. The sparse depiction of whole-body movements, coupled with a lack of visual experience watching ourselves in the world, has long implicated nonvisual mechanisms to self-action recognition. Using general linear modeling and multivariate analyses on human brain imaging data from male and female participants, we aimed to identify the neural systems for this ability. First, we found that cortical areas linked to motor processes, including frontoparietal and primary somatomotor cortices, exhibit greater engagement and functional connectivity when recognizing self-generated versus other-generated actions. Next, we show that these regions encode self-identity based on motor familiarity, even after regressing out idiosyncratic visual cues using multiple regression representational similarity analysis. Last, we found the reverse pattern for unfamiliar individuals: encoding localized to occipitotemporal visual regions. These findings suggest that self-awareness from actions emerges from the interplay of motor and visual processes.
Color and Spatial Frequency Provide Functional Signatures of Retinotopic Visual Areas
Authors: Loggia Spencer R. , Duffield Stuart J. , Braunlich Kurt , Conway Bevil R.
Published: November 2024

Primate vision relies on retinotopically organized cortical parcels defined by representations of hemifield (upper vs lower visual field), eccentricity (fovea vs periphery), and area (V1, V2, V3, V4). Here we test for functional signatures of these organizing principles. We used functional magnetic resonance imaging to measure responses to gratings varying in spatial frequency, color, and saturation across retinotopically defined parcels in two macaque monkeys, and we developed a Sparse Supervised Embedding (SSE) analysis to identify stimulus features that best distinguish cortical parcels from each other. Constraining the SSE model to distinguish just eccentricity representations of the voxels revealed the expected variation of spatial frequency and S-cone modulation with eccentricity. Constraining the model according to the dorsal/ventral location and retinotopic area of each voxel provided unexpected functional signatures, which we investigated further with standard univariate analyses. Posterior parcels (V1) were distinguished from anterior parcels (V4) by differential responses to chromatic and luminance contrast, especially of low-spatial-frequency gratings. Meanwhile, ventral parcels were distinguished from dorsal parcels by differential responses to chromatic and luminance contrast, especially of colors that modulate all three cone types. The dorsal/ventral asymmetry not only resembled differences between candidate dorsal and ventral subdivisions of human V4 but also extended to include all retinotopic visual areas, starting in V1 and increasing from V1 to V4. The results provide insight into the functional roles of different retinotopic areas and demonstrate the utility of SSE as a data-driven tool for generating hypotheses about cortical function and behavior.

Published: November 2024

The resistance of epoxy composite modified with nanocellulose and tetraethoxysilane (TEOS) to decay by white rot (Trametes versicolor) and brown rot (Coniophora puteana) fungi was investigated using EN 113 (1996) as the guideline. The objective of this study was to investigate the effect of TEOS as a cross-linked agent in epoxy/nanocellulose composite, and its resistance against white rot and brown rot fungi. The epoxy resin was mixed with 10 wt% nanocellulose. The other three sets were prepared the same, but with the addition of 1%, 2%, and 3% TEOS for each set. All types of epoxy composites were air dried in a mold at ambient temperature for seven days followed by oven drying at 80 °C for 30 min. The composites were oven dried at 103 °C, sterilized, and exposed to the fungi at 22 °C for 16 weeks. It was found that the use of 1% to 3% TEOS in the composite reduced the percent weight loss following decay by T. versicolor, but not in the case of C. puteana. Overall, all types of the composite in this study were classified as highly durable and durable against the T. versicolor and C. puteana respectively. The surface and structure of all types of composites were still intact after 16 weeks of exposure period.

Published: November 2024

For sustainable use of lignocellulosic resources, pruned tree branches of cocoa, one of the major evergreen tropical tree crops with significant economic importance worldwide, were investigated as a potential source of kraft pulp. This study determined the chemical composition, fiber dimensions, kraft pulp, and paper properties of the cocoa tree (Theobroma cacao L.) branches compared to the deciduous trees traditionally used in the paper industry. A handsheet of cocoa pulp showed promising results with narrow fiber length distribution, high paper density, and high mechanical strength. The yield of kraft pulp made from cocoa branches wood was lower. The tensile and burst indices of cocoa pulp handsheet were 2 and 2.5 times higher than that of hardwood traditionally used in the paper industry. These results suggest a potential use of cocoa (Theobroma cacao L.) tree branch wood for pulp production using the kraft process.

Higher courses as the first higher school in Lithuania
Authors: Mančinskas Česlovas
Published: November 2024

After the newly independent Lithuanian state had been established, the necessity of development of economics, education, culture, and the state governing machinery became obvious. So the society needed a sufficient amount of educated specialists, which, at this moment, especially with a higher education, had only been a few. Because of the Russian tsarist governmental politics of national oppression, and having no higher school, the country remained undeveloped for almost a century. According to the data of the first general census of the population, only 42.18% of the population of Lithuania were literate, 25.18% were half-literate, and the others were illiterate persons.
In 1919 the Lithuanian government decided not to establish a national higher school and to send young people for education to foreign higher schools. On 27 January, 1920, the Lithuanian intelligentsia of a democratic orientation decided to establish and financially support the first private higher school in Kaunas — "The Higher Courses." Z. Žemaitis was the first head of them, and J. Vabalas-Gudaitis, the next one. There were 6 departments (faculties): Humanitarian, Law, Mathematical-Physical, Technical, and Medical at the Courses, and they were headed by the deans E. Volteris, A. Janulaitis, Z. Žemaitis, T. Ivanauskas, J. Šimoliūnas, and M. Nasvytis. There were 522 unattached students and 34 lecturers.

Kharkiv Okruha in the 1920s: Number and Ethnic Composition of the Population
Authors: Skliar Volodymyr
Published: November 2024

The ethno-cultural environment of Ukraine, in particular the ethnic structure of the population and its territorial features, is an important topic of Ukrainian ethnology. The materials of censuses are the main sources for studies of the ethnic composition. The results of the 1926 census, the publication of which has been the most complete, are of unique importance for conducting such scientific research. The population of not only areas, towns, districts, but also every rural settlement without exception, as well as the ethnic composition of the population of each village council, has been promulgated. There is currently no separate investigation devoted to the study of the population and ethnic composition of the population of Kharkiv Okruha as a whole, its urban and rural population. The author’s tables have been prepared based on the processing of statistical materials of the 1926 census. In 1926 Ukrainians have constituted an absolute majority in the ethnic population of the Kharkiv Okruha as a whole, among the urban and rural population, among the population of 24 out of 27 districts, as well as among the population of 348 out of 411 village councils. In 1926 most of the territories of Kharkiv region have been characterized by the dominance of Ukrainians in terms of number and ethnic homogeneity of the population with a minimal territorial representation of scattered ethnic minorities. The level of the share of Russians and Jews among the entire population of Kharkiv is noticeable, but the majority of them are migrants. Russians have made up the majority of the population in 3 districts of the okruha. The territories of the former Kharkiv Okruha in the borderlines of 1926 now belong not only to Kharkiv Oblast (established in 1932), but also to Sumy Oblast (founded in 1939). The territory of 12 districts of the former Kharkiv Okruha has been under Russian occupation completely or partially from the end of February to the beginning of September, 2022 and suffered significant human losses and material damage from Russian aggression.
Group Sacrifice as a Marker of National Identity: Ukrainian Experience
Authors: Diedush Oleksii
Published: November 2024

The article is dedicated to the development and analysis of the group sacrifice concept. It can be defined as a group of deceased, suffered, less commonly, repressed individuals performing an act of heroic deed that influenced significantly the course of a certain more large-scale phenomenon or had significant symbolic meaning, contributing to the ideological filling of the continuation of the struggle in one form or another. In this understanding, the fallen or sufferred individuals are not objects of criminal violation by enemies but rather subjects of active, motivational embodiment of national identity. Therefore, significant attention is devoted to the theoretical and conceptual apparatus of the issue. An established name, the fact of heroism, an especially implacable enemy, initial journalistic or oral-historical coverage of the act of group sacrifice, fixation in national historiography, a specific list of group sacrifice, localization in a place and time, and a defined purpose for which the feat was accomplished are distinguished among the characteristics of group sacrifice. The functions of group sacrifice include the transmission of national identity, the formation of a national historical narrative, the glorification of civic-religious culture, and the approval of the cultural-identification basis of the nation. Ukrainian group sacrifices in the struggle for independence have taken place as early as the beginning of our modern statehood during the period of national liberation struggles of 1917–1921. The memory of them has been preserved thanks to the active work of exiled scholars in Humanities. A new chapter in the group sacrifice of Ukrainians is opened in February 2014, when a new stage of the fight against Russian imperialism have started. Thus, the Heavenly Hundred, the Cyborgs, defenders of the hero cities of Ukraine, and others have inscribed themselves in the list of fighters for Ukrainian independence through their heroic deeds. The stress-motivational potential of the group sacrifice has a huge impact on contemporary Ukrainian nation-identity practices.
Chernihivshchyna is a Northern Advanced Post: Occupation, Liberation, Prospects of Living on the Borderland
Authors: Bekh Mykola
Published: November 2024

The main events in the outlying villages of Chernihiv during the period of occupation / deoccupation are described in the article, based on the collected expeditionary materials. The interviews have been recorded in the villages of Ivanivka and Yahidne. They have been occupied by Russian regular troops for almost a month. Chernihivshchyna is one of the first regions to meet the hostile invasion of the northern neighbour. The rapid passing of Russian troops through the region, as well as their deployment among the housing stock of the population, which was a human shield for the invaders, led to catastrophic consequences in some settlements: damaged infrastructure (roads, schools), destroyed cultural heritage sites, polluted environment, and human lives were cut short. Thus, today it is important to record the state of development of the social, domestic, and cultural spheres of everyday life in the region. The attempt is made to describe the attitude of the local population to Russians in different periods of coexistence (Soviet times, independence, occupation), since the local population of the border region has always had close trade and economic ties. The testimonies recorded from the locals are extremely important not only for understanding the full consequences of the occupation of Chernihiv region, but also for Ukrainian society’s understanding of the trends in relations with its northern neighbour and for outlining an action plan to secure sovereign territories from both external invasion and internal destabilization. The communication of the local population with the occupiers through field evidences is considered in the published work. These are, in particular, illustrative aspects of the invaders’ inability to explain their own purpose of occupation, their lack of understanding of Ukrainian history and culture, the rejection of the local civic position by the military men of the RF, etc. The peculiarities of the life of villagers under occupation and during the period of deoccupation are also analysed in the article; the trends in the region’s reconstruction both at the expense of local and volunteer resources as well as through projects with Ukraine’s external European partners are considered.
Entre o antropoceno e o afrofuturismo
Authors: Antunes da Silva Raissa Lauana
Published: November 2024

A literatura contemporânea tem se reinventando através de escritoras/es que propõem novos olhares para os problemas que nos cercam, novas formas de visualizar o amanhã, as quais são capazes de apresentar os impactos das nossas ações enquanto sociedade ou de reconstruir e repensar a realidade em que vivemos. Essas transformações que acontecem no âmbito literário perpassam áreas sociológicas, filosóficas, históricas e, por que não, ecológicas, evidenciando um contato direto da ficção com os espaços que nos cercam, um emaranhamento que nos abre novas discussões, novas temáticas e novas análises literárias. Atentando-se a isso, o presente artigo tem por objetivo criar um diálogo entre o afrofuturismo e o antropoceno, aplicando essas duas discussões na literatura contemporânea para a análise das obras literárias: A parábola do semeador (2018), da escritora norte-americana Octavia Butler, distopia escrita em 1993 que aborda o fim da sociedade norte-americana nos anos de 2024 até 2027; e Um céu entre mundos (2021), da escritora brasileira Sandra Menezes, utopia que narra o retorno da personagem central para uma Terra que está sendo reconstruída após a degradação humana. Considerando que ambas as escritoras trabalham com a literatura afrofuturista, ou seja, são escritoras negras pensando através da ficção científica novas ideias de futuro, o presente artigo entrelaça a literatura negra com o antropoceno. As duas narrativas serão atravessadas por esse diálogo teórico, a fim de revisitar e repensar a literatura afrofuturista também como uma literatura que dialoga com a desconstrução e com a reconstrução do mundo. Para tanto, parto de uma confluência entre teóricos afrofuturistas, como Mark Dery (1994), Samuel Delany (1984) e Lisa Yaszek (2012), bem como com Malcom Ferdinand (2022), para pensar a literatura afrofuturista a partir do livro Uma ecologia decolonial.
Ficções da zona de sacrifício
Authors: Corrêa da Silva de Araujo André , Petrucci Sperb Maria
Published: November 2024

Este artigo examina a interseção entre o horror contemporâneo e o fenômeno do Antropoceno na obra da escritora argentina Samanta Schweblin. Inicialmente, aborda-se a conexão intrínseca entre o horror e as mudanças climáticas, destacando como a literatura de gênero é capaz de refletir e reagir aos desafios ecológicos da era atual. Schweblin, por sua vez, utiliza uma espacialidade específica em suas narrativas, focando nas monoculturas de soja transgênica no interior argentino, no que pode ser enquadrado sob o conceito de Zona de Sacrifício. Essa escolha não apenas fornece um pano de fundo vívido, mas também funciona como um meio de problematizar os cronotopos, conceito introduzido por Mikhail Bakhtin, especialmente os cronotopos clássicos do horror do norte global, que no texto são caracterizados como desempenhando um funcionamento de horror de periferia. Em seguida, o texto analisa como Schweblin desenvolve uma literatura de horror singular que desafia a história colonial da América Latina, a partir de uma perspectiva tranversal e sistêmica, que conecta as dimensões corporais, sociais e ambientais. Sua escrita evoca um sentido de estranhamento e inquietação, mergulhando nas complexidades das relações humanas e ecológicas na era do Antropoceno. Ao situar suas narrativas em um contexto latino-americano, Schweblin oferece uma perspectiva singular sobre os efeitos devastadores do colonialismo e da exploração humana sobre o meio ambiente. Em suma, o trabalho de Schweblin não apenas oferece uma visão original do horror contemporâneo, mas também serve como uma reflexão sobre as interações entre humanidade, natureza e poder em um mundo cada vez mais dominado pelo impacto humano.

Aim: Shoulder pain is the third most prevalent musculoskeletal condition that impairs function. Subacromial impingement syndrome is among the most typical causes of shoulder pain. The aim of this study was to evaluate inter-machine reliability of acromiohumeral distance measurements performed with standard ultrasound and wireless ultrasound devices in patients with subacromial impingement syndrome. Material and methods: A total of 61 participants diagnosed with subacromial impingement syndrome were included. Acromiohumeral distance was measured with wireless and standard ultrasound devices in a neutral position and at 60-degree abduction, respectively. The inter-machine intraclass correlation coefficient, standard error of measurements, and minimum detectable changes were calculated. Results: Inter-machine reliability measured in the neutral position was excellent (ICC = 0.97, 95% CI = 0.95–0.98); the standard error of measurement was 0.23 mm, and the minimum detectable change was 0.63 mm. Inter-machine reliability measured at 60 degrees abduction was excellent as well (ICC = 0.96; 95% CI; 0.93–0.97). The standard error of measurements was 0.20 mm, and the minimum detectable change was 0.55 mm. The mean difference between the two machines was 0.04 mm for the neutral position and 0.02 mm for the 60-degree abduction position. Conclusions: The study showed that wireless ultrasound devices were similar to standard ultrasound devices in measuring the acromiohumeral distance in patients with subacromial impingement syndrome. The findings could contribute to a significant improvement in the clinical use of wireless ultrasound devices.

Authors:   Emergency Medicine, The Rotherham NHS Foundation Trust, Rotherham, United Kingdom, Ahmed Ayman S. , Abdelhady Ahmed E. ,   Emergency Medicine, East Jeddah Hospital, Ministry of Health, Jeddah, Saudi Arabia
Published: November 2024

Purpose: Distal forearm fractures are one of the commonest injuries in children due to falling on an outstretched hand. Plain X-ray is the gold standard test for diagnosing fractures of long bones but it exposes patients to radiation with its associated health hazards. The use of ultrasonography has been proposed as a safer diagnostic test. This review aimed to summarize the evidence regarding the diagnostic accuracy of bedside ultrasonography for identifying distal forearm fractures in pediatric patients. Methods: Electronic search of MEDLINE, EMBASE, Cochrane Library, Google Scholar, and Best Bets databases was conducted for studies published from inception to May 2017. The search terms used included “forearm” and “fractures” and “children.” Results: Seven studies were included in the review. The overall accuracy of ultrasonography ranged from 78.6% to 99.5%. The sensitivity and specificity ranged from 85% to 100%, and from 73% to 100%, respectively. The area under the curve for ultrasonography ranged from 0.79 to 1.00. Conclusion: Ultrasound is a reliable diagnostic tool for the diagnosis of distal forearm fractures in children when performed by well-trained emergency doctors and through using an appropriate viewing method. Conducting larger prospective blinded studies on long bone injuries would be recommended.

Mainland China's 2021 restrictions on under-18s' video game time were imposed when older 2019 restrictions already applied: Omitting the historical regulatory context is misleading
Authors: Xiao Leon Y.
Published: November 2024

Investigating the impacts of addiction policymaking following implementation is important. Effective policies should be considered for emulation elsewhere, whilst ineffective policies should be repealed. Zhou et al. (2024) reported how Mainland Chinese under-18s responded to the 2021 restrictions on their online videogame playtime, which were intended to curb online gaming addiction. However, Zhou et al. failed to mention that Mainland China had previously tried to achieve the same regulatory aim by imposing rules in 2019 that were more lenient than the 2021 rules but nonetheless restricted under-18s' gameplay time. These 2019 restrictions were neither acknowledged as crucial background in the introduction section nor accounted for by Zhou et al. when interpreting their results, thus giving readers the incorrect impression that the 2021 rules were the first ones introduced and that under-18s' gameplay time was not restricted at all prior to 2021. Importantly, Zhou et al.’s entire sample of young people therefore consisted not merely of ‘heavy gamers’ as they euphemistically described them as, but ‘counterplayers’ who actively contravened the 2019 rules. The misleading omission of this context is a major limitation and misrepresentation. The results should be interpreted accordingly and not overgeneralised.

Published: November 2024

Management of human resources (HR) is important to achieve company goals. One of the activities in HR management is recruitment, selection, and training. Recruitment and selection are usually done not using a system so that the calculations are still done manually. But by processing data using the system can produce a decision in recommending prospective employees that can have a positive impact on the company. The company selection process is carried out through two stages: administrative selection and final selection in the form of psychological test assessment, interviews, ability tests and communication. The use of the Elimination Et Choix Traduisant La Realite (ELECTRE) method in the administrative selection stage and the Weighted Product (WP) method in the final selection stage is a new discovery made to get the best decision in accordance with the required criteria. By using this method the final results will be obtained namely the recommendation of several prospective employees who are fit to work in the company. The performance results of this system reach one hundred percent, the data from the system is in accordance with the expected calculation.
Development of financial literacy and fintech adoption on women SMEs business performance in Indonesia
Authors: Kurniasari Florentina , Lestari Elissa Dwi
Published: November 2024

Women-owned small businesses are crucial to the Indonesian economy. Despite this contribution, women entrepreneurs face many challenges when building their businesses, especially getting business loans. Women entrepreneurs adopt less technology and have less financial expertise than men. This study aims to determine financial literacy factors affecting women SMEs' business success and the extent of financial technology (FinTech) use as an alternative funding source to formal financial institutions. The study examines FinTech adoption using the Unified Theory of Acceptance and Use of Technology (UTAUT Theory). This study also examines how FinTech adoption mediates the indirect effect of financial literacy on SME business performance. The study uses a quantitative research approach using a judgmental sample of 270 women entrepreneurs who have previously used FinTech. The data is analyzed with SEM-PLS.

The object of research are models of optimal logic circuits based on universal Peirce-Webb functions. The problem solved is the efficiency of the technique for simplifying the Peirce-Webb functions. The extension of the non-standard system to the simplification of Peirce-Webb functions makes it possible to discover new rules of equivalent transformations of Boolean functions, and to complete the simplification procedure in one step. A feature of the simplification of functions in the Peirce-Webb basis by a non-standard system is fixing the digital project at the level of abstraction, followed by the application of the mechanism of logical synthesis to generate the corresponding equivalent at the level of gates of the logic circuit. The result of the transformation of the terms of the binary matrix in the end is some combinatorial system, metadata that can explain other data, for example, determine the minimum function for another logical basis.
The interpretation of the result consists in the use of combinatorial properties of binary structures of functions in the Peirce-Webb basis and binary structures of functions in the basic basis. These properties do not depend on the selected logical basis, which makes it possible to carry out equivalent transformations on binary matrices of Peirce-Webb functions according to the rules of the algebra of the main basis.
It has been experimentally confirmed that a non-standard system enables:
– to reduce the algorithmic complexity of simplifying the Peirce-Webb functions;
– to increase the performance of the simplification of Peirce-Webb functions by 200–300 %;
– to demonstrate the visibility of the process of simplifying functions.
In terms of application, the non-standard system of simplifying the Peirce-Webb functions could ensure the transfer of innovations to material production: from conducting fundamental research, expanding the capabilities of digital component design technology to organizing serial or mass production of novelties.

The object of this study is the process related to the fall of an uncontrolled cargo from a height of 400–600 meters relative to sea level in an air environment under the influence of gravity, air drag, and wind in the presence of an initial air speed of about 20 m/s. The study solves the task to build a ballistic model of the movement of an unguided cargo during autonomous high-precision dropping from an unmanned aerial vehicle of aircraft type. A system of equations was derived that explicitly describes the dependence of the cargo's travel speed and coordinates on time and takes into account the effect of gravity, air drag, and the influence of wind. The scope of application of the equations corresponds to drop heights of up to 400 m relative to the surface of the earth and the initial horizontal speed of the cargo up to 20 m/s. The resulting equations were analyzed using an example of a spherical load weighing 10 kg and the largest cross-sectional area of 7.1·10-2 m2 when it falls from heights of 200, 300, and 400 m relative to the earth's surface. In the absence of wind, the horizontal component of the load's speed at the moment of falling is ≈(13–15) m/s, and the vertical component is ≈(50–60) m/s. At the same time, the horizontal displacement of the load under the conditions of a weak crosswind can reach ≈(150–220) m. With a vertical wind speed profile, the equivalent constant wind speed can be determined, resulting in the same effect on the load as a variable speed wind. An algorithm for determining the point of unloading the cargo has been proposed. The cargo delivery error has been evaluated. The most important parameters are the flight time of the cargo and the drop height. In order to achieve a hit accuracy of ±5 m, an error in determining the time of the fall of the load is not more than ≈0.16 s, and an error in determining the height of the drop is not more than ±8 m

The object of this study is the technology of bread baking based on liquid sourdough and gluten-free flour mixture. The problem with this technology is that gluten-free raw materials do not contain gluten proteins, which ensure the elasticity and firmness of the dough and increase the porosity of the bread. To improve the structural and mechanical properties of the dough, new types of flour were introduced into the recipe compared to the analog recipe: quinoa, buckwheat, and oat. The positive effect of quinoa on dough quality has been known for a long time but the limitation in its use is the bitter taste caused by the content of saponins. A method of removing saponins using ultrasound (40 kHz, τ=20 min) has been proposed, which made it possible to remove 60 % of saponins and completely remove the bitterness of grains. At the same time, the content of proteins remained unchanged while the content of phenols decreased by only 0.1 mg GAE/g. The addition of 18 % (to the mass of the flour mixture) of quinoa flour and the reduction of the starch content in the recipe had a positive effect on the organoleptic parameters of the bread quality. The acidity of dough (4.4–5.2 °Н) and bread (0.6 °Н) decreased compared to the control sample, but it was sufficient for a normal fermentation process. Bread with quinoa flour had increased moisture (more than 66 %), which can negatively affect its stability during storage. An increase in the proportion of quinoa flour in the recipe by 5 % contributed to an increase in the porosity of the crumb by 2.1 %. The proposed technology for making gluten-free bread with Quartet quinoa flour based on liquid sourdough can be industrially implemented as it makes it possible to obtain a product with desirable consumer properties. The total duration of dough ripening was reduced by 1–1.5 hours, compared to the steam method, which increases the economic efficiency of the proposed technology.

The object of this study is models for predicting students’ success, constructed on the basis of machine learning methods. The paper reports results of research into the problem of improving their accuracy by expanding the data set for training the specified models. The most available are data on student actions, which are automatically collected by learning management systems. Entering additional information about students’ work increases time and resources but allows the improvement of the accuracy of the models. In the study, information about students’ work with video materials, particularly the number and duration of views, was entered into the original data set. To automate the collection of this data, the plugin for the Moodle system has been developed, which stores information about user’s actions with the video player and the duration of watching video materials in the database. Model training was carried out using Naive Bayes (NB), logistic regression (LR), random forest (RF), and neural networks (NN) algorithms with and without video data. For the models using video viewing data, accuracy increased by 10 %, balanced accuracy by 15 %, and overall performance, expressed as area under the curve (AUC), increased by 14 %. The highest prediction accuracy, with a difference of 1.8 %, was obtained by models built using RF algorithms – 87.1 % and NN – 85.3 %. At the same time, the accuracy of the models obtained by the NB and LR algorithms was 70.7 % and 76.5 %. The increase in accuracy for them was 2.3 % and 8.1 %, respectively. Analysis of calculations confirms the assumption that students’ work with educational video materials is correlated with their success. The results make it possible to find a reasonable compromise between model development costs and its accuracy at the stage of data preparation for model training.

The use of heat pumps makes it possible to reduce energy consumption in drying processes. This study addresses the problem of efficient use of a heat pump for drying, low-temperature processing, and storage of food products. The object of the study is a heat pump unit capable of operating under the drying mode or under the refrigeration processing and storage mode. Studies have been conducted to design an experimental unit, as well as to improve the energy efficiency of the cooling system. The unit includes a single-stage freon compressor, two air condensers, a water-cooled coil heat exchanger-precondenser, an air evaporator, a thermostatic valve, axial fans, and a unit control system. It has been experimentally established that, depending on the temperature level of condensation of the refrigerant (from +20 °C to +50 °C), the increase in specific cooling capacity with the heat exchanger-precondenser turned off is from 82 kJ/kg to 135 kJ/kg, and with it turned on – from 98 kJ/kg to 143 kJ/kg. In this case, the specific work of compression of refrigerant vapors in the compressor with the heat exchanger-precondenser switched off changes from 36 kJ/kg to 18 kJ/kg. And when it is switched on – from 32 kJ/kg to 10 kJ/kg. That is, the reduction in specific energy consumption is from 4 kJ/kg to 8 kJ/kg, which indicates the advisability of including the precondenser in the installation scheme. In the installation, refrigeration treatment and storage of the product can be carried out in the temperature range from –20 °C to +20 °C and drying – from +10 °C to +40 °C. Under such modes, it is possible to obtain high-quality products with long shelf lives. The results could be used to improve the designs and optimize the operation of heat-transfer drying units and their engineering calculations
