Encruzilhando espaços-tempos atra-versados e(m) cotidianos, juventudes , negritudes e quilombo
Authors: C Oliveira Beatriz Soares , Pires Andrade Elenise Cristina
Published: October 2024

O presente trabalho visa refletir acerca das questões que envolvem pensar sobre as juventudes quilombolas. Como parte de uma investigação ainda em andamento, objetiva-se no texto aborda aspectos e escolhas teóricas sobre a temática, bem como apontar caminhos e abordagens que vem sendo utilizadas, de forma a perceber as pluralidades que envolvem pensar cotidianos, juventudes e negritudes e quilombo. Parte-se principalmente dos conceitos de encruzilhada, encantamento e cotidianos. Entende-se e defende-se que, lançar os sentidos sobre esses jovens, é entende-los com sujeitos plurais, não fixos ou determinados por uma ou outra categorização - o quilombola, o rural, o jovem – mas, forjando-se e rasurando-se nas invenções cotidianas, além disso, afirma-se que o cotidiano enquanto espaçotempo de resistência e potência, permite refletir sobre os sentidos ligados a ideia de juventude quilombola. Percebe-se que, no fazer cotidiano, seja nas lutas pelos direitos da comunidade, nos eventos organizados, na relação com os mais velhos, essas juventudes se constroem e dão sentidos próprios ao ser quilombola.
Attention Deficit/Hyperactivity Disorder and Motor Planning Difficulties: A Confirmatory Study on the Overlap Between Neurodevelopmental Disorders
Authors: Zaccaria Valerio , Innocenti Alice , De Meo Giuliano , Giannini Maria Teresa , Romani Maria
Published: October 2024

Attention deficit/hyperactivity disorder (ADHD) and developmental coordination disorder (DCD) represent two frequent neurodevelopmental disorders, which may be comorbid or have common characteristics with each other. The aim of the present study was to explore the presence of DCD or motor planning difficulties in children with behavioral disorders and/or ADHD, as already stated in the literature. Motor abilities were assessed in a sample of children which underwent a comprehensive neuropsychological evaluation. A total of 43 children were included in the study and were subdivided in three groups: those with ADHD and DCD, those with DCD, and those with ADHD but also presenting motor-praxic difficulties. The first group obtained clinical scores at the considered tests, with worse performances in the balance area; in the second and third groups lower scores were observed in the manual dexterity and balance, with more homogeneous profiles. Overall, 27.3% of ADHD subjects received a diagnosis of DCD as well, whereas 31.8% showed documented motor-praxic difficulties. Our results confirmed an increased prevalence of DCD or general motor difficulties in children with ADHD compared to the general population. Further research should investigate whether a poorer motor performance assessed by standardized tests could be either due to a comorbid neurodevelopmental condition or a direct consequence of the pivotal symptomatology of the disorder.
On the Patrimonialization of Graffiti
Authors: Plesch Véronique
Published: October 2024

Abstract: "Graffiti" is not a word that one immediately associates with the concept of "heritage." In fact, the two are more often than not thought of as antonymic, and yet, as this article argues, we are at a crucial moment in what can be termed the "patrimonialization" of graffiti. Retracing the steps involved in this process of patrimonialization, starting with Raffaelle Garrucci's study of Pompeian graffiti in the first half of the nineteenth century, this essay surveys the steps that have paved the way for a recognition of graffiti's significance and of the need for its preservation. Recent initiatives demonstrate a new awareness, expressed in many ways through the work of heritage agencies and individual scholars. This article interrogates the mutations that have led to a renewed conception of graffiti as worthy of scholarly study, preservation, and display, while considering the implications and gains of its patrimonialization.

Published: October 2024

Security issues with optical access networks (OANs) are increasing as the number of users has dramatically grown. To address this problem, a full-system division multiplexing in both the time and wavelength domains has been utilized in a passive optical network second-generation (TWDM-NG-PON2) system. A secure approach to transfer data was presented by implementing the blowfish algorithm for image encryption and decryption in the OAN. Simulation results indicate effective realization of a bidirectional fiber link at 40 km with a splitting ratio of 1:256. The minimum accepted receiver sensitivity is −30.9dBm for uplink and −33.9dBm for downlink, and a symmetric high capacity of 160 Gbps rate has been obtained. The proposed algorithm in TWDM-PON offers high security with large bandwidth and an advanced long-haul network that provides effective resource usage and reinforced network authenticity.

Published: October 2024

This paper discusses the impact of pump-phase noise in the χ(2)-based optical parametric amplification process on the phase-conjugated idler. We show that the dispersive fiber propagation of the phase-conjugated idler causes the optically enhanced pump-phase noise (OEPN) effect including a group-velocity jitter. The signal penalty caused by the OEPN in the mid-link optical phase conjugation systems was quantified analytically and proved by numerical simulations. We also experimentally evaluated the OEPN with an optical parametric phase conjugator using periodically poled LiNbO3 waveguides. With a 96-Gbaud probabilistically constellation-shaped 64QAM signal, the experimental results were in good agreement with the analytically derived penalty in a standard single-mode fiber link up to 800 km.
Multi-receptive-field physics-informed neural network for complex electromagnetic media
Authors: Wang Yinpeng , Zhang Shihong
Published: October 2024

Acquiring the electromagnetic response of intricate media at the nanoscale constitutes a pivotal phase in the design intricacies of nanophotonic apparatuses. Conventional numerical algorithms often necessitate intricate and specialized treatments to accommodate the unique properties of the medium, coupled with substantial computational time and resource demands. In recent years, the advent of deep learning technology has heralded numerous advancements in the domain of computational electromagnetics, albeit with a scarcity of solvers tailored for versatile complex media. Consequently, this study introduces an innovative multi-receptive-field physics-informed neural network (MRF-PINN) designed to tackle nano optical scattering predicaments inherent in media exhibiting dispersion, inhomogeneity, anisotropy, nonlinearity, and chirality. This framework adeptly captures electromagnetic perturbations surrounding scatterers via variable-scale receptive fields, thereby enhancing prediction precision. Within the training regimen, a scale balancing algorithm is proposed to expedite network convergence. Empirical findings demonstrate that a fully trained MRF-PINN proficiently reconstructs electromagnetic field distributions within complex nanomaterials within a mere tens of milliseconds of inference time. Such quasi real-time capabilities herald a novel approach to supplant the arduous forward calculation processes inherent in nanomaterial design workflows.
SCAPS numerical modeling of CBTS/WO3 thin film solar cell
Authors: Chowdhury Towhid Adnan
Published: October 2024

The quaternary compound Cu2BaSnS4 (CBTS) has emerged as a suitable and attractive light-harvesting material due to its promising optoelectronic features as well as nontoxic and low-cost constituent elements. Yet efficiency of CBTS-based solar cells did not reach the Shockley-Queisser limit. Here, what we believe to be a novel structure ITO/WO3/CBTS heterojunction solar cell is designed and modeled using a solar cell capacitance simulator in one-dimension (SCAPS-1D). In this work, a what we also believe to be a novel WO3 as a buffer layer is proposed for the first time for the efficiency enhancement of CBTS thin film solar cells. Numerical investigation of the performance of CBTS-based solar cells without and with cuprous oxide (Cu2O) back surface field (BSF) is explored. The impact of thickness, doping density, bulk, and interface defect density of an absorber, buffer and window layer, working temperature, shunt and series resistance, back contact work function, and back surface recombination velocity were analyzed and optimized without and with the BSF layer. In this work, the optimized solar cell achieved an efficiency of 18.8%, fill factor (FF) of 83.79%, short-circuit current density (JSC) of 15.99 mA/cm2, and open circuit voltage (VOC) of 1.4 V without Cu2O BSF layer at optimal CBTS absorber and WO3 buffer layer thickness of 2 µm and 0.04 µm respectively. Furthermore, the efficiency boosted to 21.12% with VOC of 1.43 V, JSC of 16.8 mA/cm2 and FF of 87.77% by inserting 0.1 µm Cu2O BSF layer. Therefore, these results will facilitate the fabrication of an efficient and low-cost CBTS-based solar cell with promising WO3 and Cu2O as buffer and BSF layer, respectively.

Published: October 2024

While midwives are recognized as primary care-providers for maternal and new-born care in many parts of the world, India is transitioning to professional midwifery. The pathway to midwifery in India has been through integrated nursing and midwifery education. Since 2018, India has introduced an 18-month post nursing midwifery education programme. To establish a baseline for midwives’ competence and measure progress, there is a need for a quick, easy-to-administer and low-cost tool that can be used at scale to guide programme efforts. This paper describes the process of validation and testing of a tool to assess the confidence of practicing nurse-midwives as a proxy indicator for competence against the seven competency domains of the International Confederation of Midwives (2013). A total of 2198 nurse-midwives, providing maternal and new-born services at the time of the study, from 442 public and private hospitals across six states in India, responded to a self-administered questionnaire. The tool is psychometrically sound and can potentially be used in low-middle-income countries to measure confidence of midwives and nurse-midwives against international competence standards. It is suitable for quick large-scale programmatic assessments within a short time period, providing evidence to inform midwifery strengthening initiatives. The tool can be contextualized to suit specific country contexts. Since it was tested in India, where a distinct cadre of midwives is not yet established and nurse-midwives provide maternity care, the tool can be easily adapted for use in other countries in the South East Asia Region with similar contexts.

Published: October 2024

Background and objective

Dyslipidemia is a major modifiable factor in elderly people. The study objective was to assess the prevalence and associated risk factors of dyslipidemia among the Iranian population aged over 50.

Methods

This population-based cross-sectional study is part of the Iranian Longitudinal Study on Ageing conducted in Ardakan, Iran. In total, 5,197 participants aged over 50 years old were included through a stratified random sampling method. Dyslipidemia was defined in compliance with the Adult Treatment Panel III criteria. The Chi-square and independent sample t-test were used to compare categorical and quantitative variables, respectively. A logistic regression analysis was applied to determine associated factors of dyslipidemia.

Results

The mean age of the participants was 62.24±7.52. The prevalence of dyslipidemia was 68.85%. High levels of total cholesterol, triglyceride, low-density lipoprotein, and low level of high-density lipoprotein were seen among 9.74%, 24.66%, 5.54%, 19.20% of the participants, respectively. In addition, 66.05% of the study participants were under the treatment of lipid-lowering medications. Among the possible investigated risk factors of dyslipidemia, male gender (odds ratio (OR) = 0.56, 95% confidence interval (CI): 0.47, 0.68), waist circumference (OR = 1.03, 95%CI: 1.02, 1.04), diabetes mellitus (OR = 2.28, 95%CI: 1.96, 2.66), and hypertension (OR = 1.59, 95%CI: 1.38, 1.83) showed a statistically significant association (p<0.05).

Conclusion

Dyslipidemia is highly prevalent in Ardakanˈs older population. So, lipid management interventions are necessary for this population.
An ensemble deep learning model for medical image fusion with Siamese neural networks and VGG-19
Authors: Allapakam Venu , Karuna Yepuganti
Published: October 2024

Multimodal medical image fusion methods, which combine complementary information from many multi-modality medical images, are among the most important and practical approaches in numerous clinical applications. Various conventional image fusion techniques have been developed for multimodality image fusion. Complex procedures for weight map computing, fixed fusion strategy and lack of contextual understanding remain difficult in conventional and machine learning approaches, usually resulting in artefacts that degrade the image quality. This work proposes an efficient hybrid learning model for medical image fusion using pre-trained and non-pre-trained networks i.e. VGG-19 and SNN with stacking ensemble method. The model leveraging the unique capabilities of each architecture, can effectively preserve the detailed information with high visual quality, for numerous combinations of image modalities in image fusion challenges, notably improved contrast, increased resolution, and lower artefacts. Additionally, this ensemble model can be more robust in the fusion of various combinations of source images that are publicly available from Havard-Medical-Image-Fusion Datasets, GitHub. and Kaggle. Our proposed model performance is superior in terms of visual quality and performance metrics to that of the existing fusion methods in literature like PCA+DTCWT, NSCT, DWT, DTCWT+NSCT, GADCT, CNN and VGG-19.

Authors: Mehmood Asif , Amin Javeria , Sharif Muhammad , Kadry Seifedine , Kim Jungeun
Published: October 2024

Human gait recognition (HGR) is the mechanism of biometrics that authors extensively employ to recognize an individuals based on their walking traits. HGR has been prominent for the past few years due to its surveillance capability. In HGR, an individual’s walking attributes are utilized for identification. HGR is considered a very effective technique for recognition but faces different problematic factors that degrade its performance. The major factors are variations in clothing, carrying, walking, etc. In this paper, a new hybrid method for the classification of HGR is designed called Stacked-Gait. The system is based on six major steps; initially, image resizing is performed to overcome computation problems. In the second step, these images are converted into grey-scale to extract better features. After that, the dataset division is performed into train and test set. In the next step, the training of the autoencoders and feature extraction of the dataset are performed using training data. In the next step, the stacking of two autoencoders is also performed. After that, the stacked encoders are employed to extract features from the test data. Finally, the feature vectors are given as input to various machine learning classifiers for final classification. The method assessment is performed using the CASIA-B dataset and achieved the accuracy of 99.90, 98.10, 97.20, 97.20, 96.70, and 100 percent on 000, 180, 360, 540, 720, and 900 angles. It is pragmatic that the system gives promising results compared to recent schemes.
La agencia de la hija del gran Prior. La princesa María Catalina Isabel de Austria, entre Borgoña, Milán, Castilla y Flandes (1658-1714)
Authors: Bravo Martín Alberto , Quirós Rosado Roberto
Published: October 2024

Uno de los personajes más desconocidos dentro del universo dinástico de los Habsburgo es la princesa María Catalina Isabel de Austria (1658-1714). Hija natural de don Juan José de Austria y, por ende, sobrina de Carlos II, desarrolló sus primeros años de vida entre el Franco Condado de Borgoña, Milán y Castilla hasta que, en 1690, pasaría a residir en los Países Bajos españoles. Allí, establecida en el convento bruselense de Berlaymont, permaneció hasta su muerte. Ante sus constantes problemas económicos, la dama desplegó una activa labor de negociación cortesana para ver reconocido su estatus como persona de sangre real y asegurar el cobro de la pensión y las ayudas de costa que el monarca le concediese para su manutención. Su situación se complejizaría tras la muerte del último soberano madrileño de la Casa de Austria y el estallido de la guerra de Sucesión española. A partir de entonces no dudó en desplegar su agencia política tanto ante las Dos Coronas borbónicas como en las Provincias Unidas o la corte habsbúrgica de Barcelona e, incluso, enviando a su propio representante ante los plenipotenciarios del Congreso de Utrecht para que defendiera sus intereses.
La Casa de los Cinco Señores de México, un edificio olvidado de época virreinal
Authors: Nieto Márquez Miguel Ángel
Published: October 2024

El presente artículo da a conocer parte de la historia de un edificio de época virreinal de la Ciudad de México, la Casa de los Cinco Señores. Aunque dicho inmueble no se conserva, la consulta de diferentes documentos del Archivo General de Indias (Sevilla) ha permitido hallar múltiples datos que demuestran la relevancia que tuvo a finales del siglo XVIII. Así pues, ha podido documentarse que esta casa de vecinos se convirtió en sede provisional del Tribunal de la Acordada y posteriormente en cuartel de dragones. En dicho proceso participaron personalidades relevantes de la capital mexicana, caso del arquitecto Francisco Guerrero y Torres y del ingeniero Pedro Ponce Camacho, quienes protagonizaron una serie de polémicas que condicionaron la materialización de las obras proyectadas.
Max Weber y la renovación de liderazgo político en el liberalismo de izquierda weimariano 1919-1920
Authors: Lemke Duque Carl Antonius
Published: October 2024

Este estudio versa sobre el discurso político de los liberales de izquierda en Alemania durante la joven República de Weimar. Max Weber (1864-1920) y su concepto de liderazgo político son significativos a este respecto, precisamente, de cara al conflicto interno del liberalismo alemán entre una vertiente de izquierda y otra de derecha. Dicha crispación. originada en el siglo diecinueve, fue persistente debido al profundo escepticismo entre la burguesía liberal respecto al nuevo elemento plebiscitario de la Constitución de Weimar, rechazado por el conservadurismo. Ante este contexto, los liberales de izquierda buscaban incrementar su perfil político y renovar su personal dirigente.
Disability and prognostic factors of MS severity: An Algerian cohort study
Authors: HECHAM N. , TAZIR M.
Published: October 2024

Background
The evolution of multiple sclerosis (MS) is highly variable. Predicting this evolution at the beginning of the disease will help in the therapeutic management. The objective of this study was to describe the clinical characteristics and to identify early predictors of long-term disability among MS patients in Algeria.

Methods
We performed a descriptive and retrospective study of 400 MS patients followed over a 4-years period from July 2012 to July 2016 in the neurology department of Mustapha Bacha hospital in Algiers. The following parameters were systematically assessed for each patient: Age at onset, gender, relapses, initial demyelinating event, interval between first and second attack, residual deficit after first attack, onset of the progressive course, time of assignment of the successive scores of irreversible disability and type of disease modifying therapies. Univariate and multivariate Cox models were used to determine factors influencing time to Expanded Disability Status Scale (EDSS) 4 and 6.

Results
During the follow-up of this cohort of MS patients, a total of 144 (36%) and 83 (20%) patients reached EDSS scores 4 and 6 respectively. The median times from the onset of MS to assignment of a score 4 and 6 was 10 years and 19 years, respectively. Using the MSSS severity score, and after univariate analysis we identified several risk factors predictive of disease severity. These included male sex (P= 0.002), age of onset ≥ 40 years (P= 0.001), pyramidal (P= 0.0001), cerebellar (P= 0.002), and poly-symptomatic (P=0.0001) onset of the disease, incomplete recovery after the first attack (P= 0.0001), a high number of attacks during the first 2 years (P= 0.04) and the progressive form (P=0.001), and all these factors were correlated with a high MSSS score. However, prognostic factors in the multivariate binomial logistic regression analysis were limited to pyramidal onset, incomplete recovery after the first attack, short interval between the first and second attack, and progressive onset.

Conclusion
On the whole, the early predictive factors of disability in MS among Algerian patients were age of onset over 40 years, pyramidal onset, incomplete recovery after the first attack, short interval between the first and second attack and progressive form at onset. To increase the generalizability of findings, a national MS registry is strongly recommended, as well as long-term follow-up epidemiological studies.
Параметрическая идентификация сосредоточенных воздействий в многомерных обратных задачах теплопроводности
Authors: Diligenskaya Anna Nikolaevna , Bochkareva Irina S.
Published: October 2024

Работа посвящена дальнейшему исследованию и построению конструктивных методов последовательной параметрической оптимизации неизвестных характеристик нестационарных процессов технологической теплофизики на компактном множестве непрерывных и непрерывно-дифференцируемых функций. Предложенная методика распространяет разработанный алгоритмически точный метод решения на многомерную постановку обратных задач технологической теплофизики и позволяет отыскать физически обоснованную идентифицируемую характеристику на последовательно сходящихся компактных множествах.
В качестве объекта исследования рассматривается двумерное осесимметричное тело канонической формы, где искомой функцией является сосредоточенная величина мощности внутренних теплоисточников. Задача сформулирована в равномерной метрике оценивания температурного отклонения расчетного состояния от экспериментального. В качестве математической модели рассматриваемого объекта используется его модальное описание, на основе которого проведена редукция исходной обратной задачи теплопроводности, сформулированной в экстремальной постановке, к задаче оптимального управления.
Использование предварительной параметризации искомой характеристики процесса приводит к ее представлению в форме кусочно-параболических функций, конкретизируемых в рамках выбранной структуры с помощью вектора параметров. Количество учитываемых параметров определяет точное представление идентифицируемой величины, а их значения отыскиваются в результате решения полученной задачи параметрической оптимизации. Для решения полученной задачи математического программирования относительно оптимальных значений вектора параметров используются, аналогично одномерному случаю, альтернансные свойства искомых экстремалей, в результате чего задача сводится к замкнутой системе соотношений.
Полученные результаты демонстрируют эффективность распространения конструктивного метода последовательной параметрической оптимизации, опробованного на одномерных обратных задачах теплопроводности, на решение двумерных задач с использованием их модального представления. Увеличение числа параметров решений, образующих кусочно-параболическую форму искомой зависимости, приводит к уменьшению погрешности восстановления как искомой сосредоточенной функции, так и пространственно-временного температурного поля во всей двумерной области определения пространственных переменных.
Гравитационное поле однородного куба. Классический и релятивистский случай
Authors: Makarov Valeriy Nikolaevich , Shleiger Leonid Alexandrovich , Karasev Alexander Alexanderovich
Published: October 2024

Вопрос исследования гравитационного поля тел сложной формы (не относящейся к шарообразной) представляет большой интерес для геофизики, астрофизики, математической физики и других областей. Статья состоит из двух частей. В первой части представлен краткий литературный обзор различных методов расчета потенциала гравитационного поля однородного куба в рамках классической механики: получение аналитического решения; как частный случай задачи нахождения гравитационного поля полиэдра; методом конечных элементов; методом мультипольного разложения. Более подробно проанализирован метод расчета потенциала гравитационного поля однородного куба с помощью аналитического решения и мультипольного разложения. Во второй части статьи описан релятивистский случай гравитационного поля однородного куба в рамках постньютоновского формализма в первом и втором приближении. Данный метод расчета выбран по причине чрезвычайной сложности получения решения с помощью уравнений Эйнштейна. Ранее подобные задачи для тел с формой куба не рассматривались. Для решения задачи выбрана физическая модель - координатный равновесный куб, заполненный несжимаемой жидкостью с нулевой скоростью и постоянной плотностью. Получены релятивистские поправки для временной и пространственной координаты. Получен точный аналитический вид этих поправок для области вне куба, а также компоненты метрического тензора. Дано краткое сравнение полученных результатов для релятивистского случая с результатами классического ньютоновского случая. Для области внутри куба решение получено с помощью численных методов. Полученные результаты с достаточной точностью определяют параметры гравитационного поля для однородного куба, рассмотренного в рамках релятивистского подхода. Основное приложение этой задачи в рамках релятивистской физики относится к области математической физики (или, шире, математики).
Математическое моделирование массопереноса в электромембранных системах в гальванодинамическом режиме с учетом электроконвекции и реакции диссоциации/рекомбинации молекул воды
Authors: Uzdenova Aminat М.
Published: October 2024

Массоперенос в электромембранных системах в режимах интенсивного тока сопровождается возникновением дополнительных механизмов переноса, которые существенно влияют на эффективность их функционирования. Согласно современным представлениям для разбавленных растворов электролитов среди таких механизмов особенно важными являются электроконвекция и реакции диссоциации/рекомбинации молекул воды. Эти процессы оказывают противоположное действие на эффективность электромембранных технологий.
В исследованиях мембранных систем активно применяются математические модели, учитывающие влияние указанных механизмов, однако они обычно описывают только потенциодинамический режим, при котором устанавливается скачок потенциала в системе. Для интерпретации обширной базы экспериментальных данных по гальванодинамическому режиму (при фиксированной плотности тока) также необходимы инструменты теоретического анализа.
Цель данной работы заключается в разработке математической модели массопереноса в слое раствора электролита у ионообменной мембраны с учетом электроконвекции и диссоциации воды в гальванодинамическом режиме. Модель основана на системе связанных уравнений Нернста-Планка-Пуассона-Навье-Стокса, дополненной новым гальванодинамическим граничным условием для потенциала.
С использованием разработанной модели впервые рассчитаны хронопотенциограммы мембранной системы с учетом влияния как электроконвекции, так и реакции диссоциации/рекомбинации молекул воды. Результаты показали, что отношение концентрации продуктов диссоциации воды к концентрации ионов соли определяет баланс эффектов электроконвекции и диссоциации.
Рассмотрены следующие варианты соотношения эффектов электроконвекции и диссоциации молекул воды:
1) значимое влияние на массоперенос оказывает электроконвекция, в то время как влияние диссоциации воды минимально;
2) электроконвекция и диссоциация существенно влияют на процессы переноса: образование дополнительных носителей заряда в результате диссоциации молекул воды снижает скачок потенциала в слое раствора электролита, что уменьшает интенсивность электроконвекции, в то время как развитие электроконвекции, в свою очередь, замедляет процесс диссоциации;
3) продукты интенсивной диссоциации молекул воды тормозят развитие электроконвекции.
Macroeconomic Trends in the Development of the Russian Far East in the First Half of 2024
Authors:   Economic Research Institute FEB RAS, Prokapalo Olga
Published: October 2024

Based on operational statistical, analytical and expert information, an analysis of the economic and social situation in the Far Eastern Federal District in the first half of 2024 is carried out in comparison with 2022–2023. It is shown that while instability and contradictory development trends in certain sectors of the economy persist, a sharp decline in the macroeconomic context is not observed. The output index of basic economic activities shows positive dynamics, but the active growth rate has slowed down. This does not currently allow us to talk about a stable phase of economic growth. The formation of growth rates in the industry of the Far Eastern Federal District was positively influenced by an increase in mining production for the main raw materials, an increase in the production of aviation and engineering products, certain types of non-metallic mineral products, and prefabricated wooden building structures. The positive dynamics and growth of investments in fixed assets were associated with the implementation of large investment projects in the field of railway and port infrastructure, mining, and manufacturing. There is a high level of inflation despite tight monetary policy. Consumer demand continues to expand in certain categories due to the growth of real incomes of the population

Published: October 2024

Wild macrofungi have potential functions in ecosystems and sustainable developments through their roles in waste management, human health and societal upliftment. However, there is limited knowledge of wild macrofungi in Iraq. Three interesting collections within Chlorophyllum, Mycenastrum and Ossicaulis genera related to basidiomycetes were discovered in central and northeastern parts of Iraq in 2022 during a field investigation on wild macrofungi. Molecular identification and morphological characterization were carried out for these collections. The molecular phylogenetic and phenotypic analyses confirmed that isolates are related to three species within two families )Agaricaceae and Lyophyllaceae) belonging to the order Agaricales and class Agaricomycetes. Based on the current publications, these species were the first records from Iraq. Chlorophyllum agaricoides, Mycenastrum corium and Ossicaulis salomii sequences were submitted as the first sequences from Iraq into the international biological database GenBank. The molecular phylogenetic tree formed three independent lineages in each genus with high support. The introduced species can easily be separated from closely related species in an evolutionary framework. The study's results might aid in further investigations into the macrofungi in Iraq.

V mlekarni Hruševje smo povečali število parametrov za oceno kakovosti surovega mleka in zaostrili kriterije za njegovo razvrščanje v plačilne razrede. Analizo podatkov smo opravili za 439 pridelovalcev iz občine Postojna, ki so oddajali surovo mleko v obdobju junij 93 - marec 95. Število pridelovalcev, katerih surovo mleko je bilo uvrščeno v kakovostni razred "Ekstra", se je kljub stalnemu zaostrovanju kriterijev povečalo iz 40 (13%) na 106 (43%) in tistih v zadnji kakovostni razred znižalo iz 142 (46%) na 1 (0,40%). Povprečna mesečna količina oddanega surovega mleka na pridelovalca se je povečala iz 534 na 970 litrov. Kljub zmanjšanemu številu pridelovalcev pa se je povečala tudi skupna mesečna količina oddanega surovega mleka in sicer iz 206 553 na 241 566 litrov. Iz napisanega lahko zaključimo, da je "Pravilnik o določanju odkupne cene kravjega mleka" pozitivno vplival na kakovost in strukturo pridelovalcev ter tako uresničil namen zakonodajalca po nekoliko večji intenzivnosti in posodobitvi pridelave.

Published: October 2024

The paper reports the results of different investigations done by scientists of FG Milcherzeugung in the past. A short introduction about the defence mechanisms of the teat against invasion of pathogens shows the importance of the liner and its movement in mastitis prevention. Hamann' s model of "pressure changes and mastitis" - slightly changed - serves as starting point for discussion of the results of our investigations of influence of vacuum fluctuations on liner movement, liner movement and stripping, control of liner movement to decrease strippings without increasing machine on time. The discussion is supplemented by results of investigations of the role of milking systems in udderhealth of herds.

A pedagogical evaluation of an institution's digital assessment platform (DAP): Integrating pedagogical, technical and contextual factors
Authors: Slade Christine , Mahon Kathleen , Lynagh Jacqueline , McGrath Dominic , Sheppard Karen , Ahsan Syed Qasim Muhammad , Benson Karen
Published: October 2024

An assessment for learning approach is foundational for student learning. The necessity to shift teaching and learning online as a response to COVID-19 has propelled digital assessment into the mainstream within higher education institutions. User experience is a common indicator of effectiveness of technologically enhanced initiatives; however, measuring the pedagogical impact of digital assessment initiatives has not been straightforward. This paper presents a pedagogical evaluation, incorporating staff and student perspectives, of a digital assessment platform (DAP) at a large Australian metropolitan university. Data were collected using surveys, interviews, focus groups and case studies and incorporated findings from student evaluations of courses and a student-staff partnership project. Results highlight strong pedagogical reasons for continuing the digital assessment initiative, while also identifying constraints and opportunities for improvement. The insights generated through this evaluation emphasise the importance of considering technical, pedagogical and contextual factors and the interplay between the factors. In a quality assurance climate, where the demand for this type of institution-wide evaluation is increasing, this study contributes an approach that addresses some of the complexities and challenges of evaluating digital assessment initiatives in higher education. Future research is needed to understand more fully the relationships between pedagogical and contextual factors when undertaking an evaluation.
 
 Implications for practice or policy:

The DAP enabled the (re)design of authentic, inclusive, engaging and secure assessment tasks.
Educator support is critical in learning the system and  creating assessment with high pedagogical merit.
Student familiarisation opportunities with using the DAP are beneficial.
The DAP’s longevity within the institution is crucial considering the significant effort required of educators and students.
Contextual influences blur understanding of pedagogical factors.
Fostering a “Culture of Conflict” among Children
Authors: Cywińska Małgorzata
Published: October 2024

This article aims to explore the constructive resolution of interpersonal conflicts, with a particular focus on childhood. It highlights the necessity for “conflict education” and the cultivation of a “culture of conflict” from early stages of life, emphasizing the importance of developing appropriate competencies during childhood for harmoniously resolving both personal and interpersonal conflicts. These are especially emotional-social and cognitive skills as well as problem-solving abilities. Well-designed programs for fostering constructive conflict resolution among children, along with specific methods and heuristic techniques, facilitate the development of a range of these competencies in children.

The article deals with the broadly defined topic of supporting the emotional and social development of children and its impact on the formation of mental resilience. The text consists of 3 parts. The first one provides an overview of the theoretical representations of key concepts such as emotional-social development and its support and mental resilience. The second part presents the results of our own research on the developmental support of young children as perceived and experienced by their care-givers. The study concludes with a summary.
Betweenness isomorphisms in the plane — the case of a circle and points
Authors: Doležal Martin , Kolář Jan , Morawiec Janusz
Published: October 2024

Two subsets A, B of the plane are betweenness isomorphic if there is a bijection f : A → B such that, for every x, y, z ∈ A, the point f(z) lies on the line segment connecting f(x) and f(y) if and only if z lies on the line segment connecting x and y. In general, it is quite difficult to tell whether two given subsets of the plane are betweenness isomorphic.

We concentrate on the case when each of the sets A, B is of the form C ∪ D where C is a circle and D is a finite set. We fully characterize the betweenness isomorphism classes in the family of all circles with three collinear points inside. In particular, we show that there are only countably many isomorphism classes, for which we provide an algebraic description.
Trust and Safety work: internal governance of technology risks and harms
Authors: Shulruff Toby
Published: October 2024

Trust and Safety work mitigates certain social risks and harms of digital technologies. In a landscape that is only slowly establishing regulatory oversight mechanisms, Trust and Safety work performs a type of internal governance by attempting to mitigate disinformation, online harassment, extremism, and other harms accelerated or amplified by technology products and services. With origins in content moderation, Trust and Safety work now also includes product advice for online services and IRL (in real life) products. Attention to Trust and Safety work can complicate a monolithic view of what tech work is and who does it, as well as point to locations for intervention as we seek to promote Public Interest Technology in globally impactful sociotechnical systems.
An Eteocypriot-Greek bilingual inscription and the meaning of Cypriot eupatridai
Authors: Pestarino Beatrice
Published: October 2024

This paper investigates the eupatridai of Cyprus and their roles on the island. It examines the only two attestations of the Greek term eupatridēs in inscriptions from Amathous and Kafizin, namely IG XV 1.1 n° 7, an original Eteocypriot- alphabetic Greek monumental decree and IG XV 2.1 n° 67, an alphabetic Greek private dedication. Contrary to previous scholarship, which claims that Cypriot elites easily assimilated into the emerging Ptolemaic administrative apparatus, a deeper analysis of the title eupatridēs demonstrates that the integration process was protracted and uneven. While the assimilation of the upper class did occur, it only happened at a later stage. The study shows that this title was introduced to the island in the late Classical period, likely from Greece, retaining primary meanings it had in Classical Athens. It designates members of local elites who fought to maintain their superior status and preserve the traditional Cypriot socio-political structure - which entailed their great prestige and privileges - during a transitional period from the end of the 4th century BCE until the second half of the 3rd century BCE. During those years, the wars among the diadochi, who aimed to take possession of Cyprus, threatened the traditional subdivision of the island into city-kingdoms, which ultimately dissolved under Ptolemaic rule (c. 294-258 BCE). The appearance of the title eupatridēs in late Classical and early Hellenistic inscriptions may be a significant testimony to the Cypriots’ initial reaction against contemporary political upheavals and the introduction of a new administration.

This article presents a corrected reading of the traces of the Old Phrygian inscription on the Arslan Kaya monument in the Phrygian Highlands, attesting to the name of the goddess, Materan, and providing notice of stylistic details that confirm the dating of this monument to the first half or middle of the sixth century BCE.
A misidentified Old Phrygian parietal graffito from Salihler
Authors: Obrador-Cursach Bartomeu
Published: October 2024

This paper revisits a previously published graffito read among other Greek inscriptions on rock near Salihler, reinterpreting it as an Old Phrygian text that features an anthroponymic sequence. While one of the names, urakas, has been documented previously in Gordion, aᴪiyas is entirely new to the Phrygian corpus. Notably, this identification provides a new instance of the much-debated Phrygian letter no. 22.
New Urban Tourism: an On-Site Analysis of City Tourism’s New Trend in Selected Spots in the Destination of Munich, Germany
Authors: Rübesamen Francesca , Pillmayer Markus
Published: October 2024

A shift in travel behavior is taking place within urban tourism. Experienced repeat visitors want to discover cities away from tourist centers and traditional attractions. They want to gain insights into everyday life in the city and explore it off the beaten track. This phenomenon is called New Urban Tourism (NUT).

This paper aims to determine whether NUT is a noteworthy phenomenon in Munich. For this purpose, three research questions were formulated.

A qualitative content analysis of travel blog entries about insider tips in Munich was conducted to answer the research questions. The goal was to identify the two insider tips that were most often mentioned. Here, face-to-face interviews with tourists and residents were conducted. The tourists were asked questions about their travel and information behavior to determine whether they could be classified as New Urban Tourists. The residents, in contrast, were asked to indicate whether they notice the presence of tourists and how this influences their perception of the neighborhood.

NUT can be described as a notable phenomenon in the city of Munich. Recommendations for future research include examining the impact of NUT on Munich and identifying the specific aspects of urban ordinariness that New Urban Tourists deem worth experiencing.
Identifying
mïmï
as ‘Linseed’
Authors: Russell Jonny
Published: October 2024

mïmï
appears to have diverse applications, appearing in administrative documents, jar labels, depictions of commodity transportation, as well as being used in therapeutic recipes. To date, a consensus for its translation has not been reached. This article re-evaluates the suitability of past identifications in terms of new perspectives in Egyptology, and explores an extended corpus of source material that together suggest a new identification, ‘linseed’, is more appropriate. The hypothesis is further supported through the recreation and discussion of the materiality of ancient Egyptian medical recipes composed of mïmï and other ingredients with secure translations, and demonstrates: 1) that linseed was a commodity which was taxed, stored, and distributed by the ancient Egyptian administration; 2) that the effect of this product upon the body was observed and harnessed in therapeutic medical recipes.
Boston MFA 38-2-5: A Limestone Fragment with a Hieratic Inscription Presumably from the Reign of Khufu
Authors: Jüngling Johannes
Published: October 2024

This article contains the description, translation, and discussion of Boston MFA 38-2-5, a limestone block found during excavation works at mastaba G(iza) 1203 carried out in 1938 under the supervision of G. A. Reisner. The object bears a dated hieratic inscription in red paint that for the first time is comprehensively translated and analysed. Using up-to-date digital image-enhancement processes, the reading of the date is improved, and certain lexical and grammatical features (the apparent use of a cardinal number instead of an ordinal, names of workforce units, etc.) are discussed. It is argued that the object had been deposited intentionally within the filling of the mastaba during its construction. The article contains a small palaeographic overview of the hieratic signs employed in the inscription.
