Pau Lawrence Dunbar’s Harriet Beecher Stowe and We Wear the Masks Represent the Life of Slaves Post Abolishment of Slavery
Authors: Aware Rupali , Alhat Swapnil Satish
Published: May 2023

In all the civilizations there has existed slavery of one or the other form and it had acceptance from the contemporary society. If you are a slave then there is nothing you can do about it you will have to bear it meekly. The American slaves were different, they were brought there from some other continent and their look and physique were also different than the Europeans settled in America, thereof their rights were ignored and assumed that they did not have any rights. Nonetheless when the slavery was abolished from America there was revolt and civil war took place. But no one thought about the slave’s livelihood post abolition of slavery and this is where Dunbar comments upon. His poetry throughs lights on this aspect of the former slaves and their kids, they were free but did not have any skill or way of livelihood. In this present paper I would endeavour to trace this aspect of Dunbar’s poets.

Демократизація науки і суспільства в глобальних умовах соціальної турбулентності
Authors: Kubalskyi Oleh
Published: May 2023

В умовах соціальної турбулентності, що характеризують розвиток глобальної цивілізації в останнє десятиліття, демократизаційні процеси набувають різноманітних, непередбачуваних форм. Це актуалізує соціально-філософську рефлексію щодо нових форматів, специфікацій та тенденції демократизації в різних країнах. На українському тлі особливо яскраво проявляються проблемати-чні аспекти демократизації у просторі соціальної турбулентності. У статті аналізується, наскільки важливою є демократизація науки для загального впровадження демократично-правових прин-ципів у державотворчий процес загальнонаціонального характеру. Наголошується, що демократизація науки продовжує демократизацію суспільства і є такою діяльністю, що в принципі передбачає і насправді сприяє демократичним практикам у ширшому соціальному контексті. Підсумовується, що демократизація передбачає поступовий перехід від недемократичних форм і методів управління та організації усіх сфер суспільного життя, включаючи науку, до демократії, запровадження демократичних інститутів, практик і цінностей. Потреба в демократизації науки спричинена не лише фактором тривалого розвитку вітчизняної науки в умовах спочатку тоталітаризму, потім демократичного транзиту, а й через величезний вплив результатів наукових досліджень на суспільне життя. Демократизація науки потрібна для прогресивного розвитку самої науки та всіх сфер, на які вона впливає, а також з метою покращення якості демократії й прискорення демократизації суспільства.

Material y método: La investigación se realizó auscultando a 61 escolares entre niños y niñas del nivel primaria de una Institución Educativa, para ello cada escolar fue llevado a un ambiente separado del aula de clases y se les revisó la cabeza, especialmente la zona retroauricular, los piojos en estadios adultos, ninfas o huevos fueron recogidos y depositados en viales de vidrio con alcohol a 70º y rotulados con un código para identificar a cada estudiante. Las muestras colectadas fueron transportadas al laboratorio donde fueron observados a través del estereoscopio para confirmar la infección con el parásito. Resultados: De los escolares examinados 20 dieron positivos a ésta infección, lo que equivale a una prevalencia de 32,8% y del análisis inferencial se obtuvo un Chi-cuadrado = 25,25 con un p-valor = 0,000 < 0,05, con lo que se determinó que existe relación entre la infección con piojos y el sexo de los escolares. Conclusiones: La prevalencia de infección por piojos es alta en población escolar del nivel primaria en las zonas urbanas periféricas de la ciudad de Lima y puede acrecentarse en las provincias de nuestro país, además, la pediculosis capitis tiene relación significativa con el sexo de los escolares, siendo el sexo femenino la población vulnerable para esta infección, debido a que las mujeres llevan el cabello largo lo que facilitaría la infección.
Comprehensive Self-evaluation of Teacher’s Literacy for Students Directed to Rural Schools
Authors: Xu Haiying , Hsu Wei-Ling , Bao Ruiwen , Zhu Hao , Song Shanyu
Published: May 2023

The quality of training rural students in schools is related to the sustainable development of rural education. Thus, it is important to analyze the characteristics of the self-cognition evaluation of teachers’ quality in rural schools. Taking Huaiyin Normal University as an example and conducting a questionnaire survey of 144 students, we drew the following important conclusions through descriptive statistical analysis and chi-square test. (1) The self-evaluation of self-development was relatively lower than average. (2) The self-evaluation of students’ morality, professional competence, and self-development of students in the middle of Jiangsu was slightly worse than that of northern Jiangsu. (3) The difference between urban and rural areas was not significant. (4) The higher the grade, the greater the self-evaluation, but the self-development literacy was not improved significantly. In response to these problems, the following suggestions were made. Geography-oriented teacher training assessment must be introduced in an elimination system. Also, teachers need to focus on career planning and enhance the sense of educational mission. At the same time, teachers are required to focus on self-reflection and enhance their self-learning ability.
Ekosocjalizm: między ruchem społecznym a teorią marksowską
Authors: Bielińska Katarzyna
Published: May 2023

Celem tego artykułu jest analiza znaczeń pojęcia ekosocjalizmu we współczesnym dyskursie filozoficznym i politycznym.

W pierwszym kroku przeprowadzam rozróżnienie pomiędzy ekosocjalizmem jako ruchem a ekosocjalizmem jako teorią. Globalny ruch ekosocjalistyczny jednoczą postulaty polityczne. W jego skład wchodzą jednak nurty o różnorodnych założeniach teoretycznych. Skupiam się na opozycji pomiędzy nurtami nawiązującymi do tradycji marksistowskiej a nurtami, które w ślad za Joanem Martinezem-Alierem można nazwać „neonarodnictwem ekologicznym”, czyli odwołującymi się do tradycyjnych etyk i wartości istniejących społeczności, tak jak w przypadku licznych ruchów rdzennych i ekofeministycznych. Nurty te różnią się poglądami na wiele kwestii, w tym na kwestię rozwoju.

W drugim kroku, rozważając ekosocjalizm jako teorię, wyróżniam dwa stanowiska. Zgodnie z pierwszym z nich, reprezentowanym przez Joela Kovela i Michaela Löwy’ego, myśl Marksa należy uzupełnić o wymiar ekologiczny. Zgodnie z drugim stanowiskiem, którego przedstawicielem jest John Bellamy Foster, ekosocjalizm to idea Marksowska, przedstawiona w Kapitale. Wysuwając na pierwszy plan pojęcia metabolizmu i rysy metabolicznej, Foster odkrywa ekologiczny, we współczesnym sensie, wymiar myśli dojrzałego Marksa.

Wykazuję, że należy odróżnić ekosocjalizm w znaczeniu politycznym od ekosocjalizmu w znaczeniu filozoficznym. Na poziomie filozoficznym natomiast, rozbieżność stanowisk ma swoją genezę w interpretacji ontologii Marksa: Kovel i Löwy są kontynuatorami tradycji marksizmu-humanizmu, a Foster zrywa z tą tradycją i odczytuje ontologię Marksa w perspektywie materializmu epikurejskiego.
Hybrid βΩ-Indexing Fractal Slotted Multiband Antenna for Electronics Wireless Sensor Applications
Authors: Shindhja N.M.Mary , Varshney Atul
Published: May 2023

In this proposed work a compact, low profile, inset-fed βΩ-space-filling curve-based slotted fractal antenna for multi-band wireless applications and narrow band operations is designed, fabricated, and successfully tested. The measured results of the reflection coefficient and E-plane and H-plane gain radiation patterns are found to be very concord with simulated corresponding results. The antenna resonates at five resonance frequencies 1.91GHz (1.86-1.93GHz), 3.12GHz (3.03-3.21GHz), 5.56GHz (5.50-5.60GHz), 10.75GHz (10.55-11.20GHz) and 13.94GHz (13.72-14.17GHz) with narrow band. Therefore the proposed antenna is adopted for the applications like PCS-1900 (n2 band: 1850-1910MHz), rail mobile radio (1900-1910MHz), DCS-IMT gap (n98/n39 band: 1880-1920MHz), WCDMA (1900MHz), X-band (10.55-11.20GHz) and Ku-band (13.72-14.17GHz) applications. The antenna parameters gain, directivity, and efficiency are greatly improved by the 50% reduction in ground length. A  Good impedance matching is achieved by the use of inset feeding with a 50Ω port at an operating frequency 3.1GHz. The antenna exhibits 2.94dBi gain at the operating frequency. A new hybrid βΩ- space-filling curve has been utilized for the slotted fractal proposed antenna design. The antenna is fabricated on an FR4 substrate with compact dimensions (39.05mm x 32.25mm x 1.6mm) at a frequency 3.1GHz.

Authors: Forte Silva Marcus Vinícius , Garat de Marín Mirtha Silvana
Published: May 2023

Los cambios provocados por la globalización han construido una nueva realidad para los medios de producción y comunicación, la calidad de vida y el comportamiento, favoreciendo el surgimiento de proyectos en todo el mundo. Durante el gobierno del Partido de los Trabajadores (2003-2016), Brasil siguió esta tendencia, transformándose en un gran sitio de construcción, donde la ingeniería de exploración de petróleo y gas asumió un papel importante para la economía nacional. La alta demanda mundial de energía y el descubrimiento de la provincia del presal permitirían al país convertirse en exportador de energía y superpotencia para el año 2030, definiendo el carácter estratégico de los megaproyectos de exploración de petróleo y gas en la Cuenca de Santos, São Paulo. El programa de gobierno en la era del PT ofreció a Brasil un terreno fértil para el desarrollo económico, pero también para la ilegalidad, cuando una nueva realidad sacada a la luz en 2014 por la Operación Lava Jato desencadenó el mayor escándalo de corrupción en la historia de Brasil. La combinación de complejidad y corrupción provocó retrasos en la entrega de petróleo al mercado de consumo y enormes pérdidas financieras. La situación exigía iniciativas de apoyo a la gestión de horarios que estén a la altura del desafío, donde la respuesta esperada es la aplicación de un método de análisis de horarios – el Método FORTE v. 1.0 – responsable de la primera iniciativa integrada dirigida al cumplimiento, gestión de proyectos y conocimiento corporativo, ajustada a la realidad de los grandes proyectos de ingeniería en Brasil. La situación requería una solución de TI con diferentes características – Oracle Primavera P6 – y el resultado de la iniciativa es un conjunto de logros más allá de la gestión de proyectos, permeando todo el tejido organizacional.

Authors: Arora Anil , Pandav Karan , Asnake Getnet
Published: May 2023

Osteomyelitis around the knee joint if not treated in time will lead to degeneration of knee joint and those patients will have symptoms for which a total knee arthroplasty would be indicated. Very few studies are available in the literature, in which the surgeons have performed primary total knee arthroplasty in cases of previous quiescent osteomyelitis around the knee. The objective of these reports is to investigate whether prior quiescent osteomyelitis around the knee joint would result in high rate of recurrence of infection after primary total knee arthroplasty? Which antibiotics should be used if intraoperative cultures are negative in patients with quiescent osteomyelitis and what would be the duration of antibiotics? Here we present case reports of 2 patients who underwent total knee arthroplasty after previous distal femur osteomyelitis and their functional outcomes aftertotal knee arthroplasty with a follow-up period of 2 years. Both the patients preoperatively were limited to indoor ambulation and had signicant difculties with stair climbing, reported signicant improvement in climbing up and down stairs, ambulatory distance and activities of daily living in the post-operative period. None of the patients had clinical signs of deep prosthetic joint infection at 2 years follow-up

MRI AS A DIAGNOSTIC TOOL FOR LOW BACK PAIN: ADVANTAGES AND LIMITATIONS-OBSERVATIONAL STUDY
Authors: Senthil Velmurugan V. , Ragupathi Siddharth , Ragupathi Ashwin
Published: May 2023

Low back pain (LBP) is one of the most common health problems among the population all over the world including all age groups. LBP has become an epidemiological burden globally. It is the number one cause of years leading with disability. The most common age group affected includes 31-50 years. Advanced imaging studies, including computerized tomography (CT) and magnetic resonance imaging (MRI), are frequently ordered in the setting of LBP. Structural abnormalities are commonly identied by CT and MRI in patients complaining of low back pain, however, these ndings are also found in asymptomatic patients. [1] The study aims to evaluate the cause of low back pain using MRI as a diagnostic tool. This is an observational study conducted in The Department of Radiology, at Mahatma Gandhi Memorial Government Hospital, Trichy. The study was conducted over a period of 1 month. The study population size is 100 and includes the 10-70 years age group. Low back pain can have a variety of underlying causes, including spinal pathologies and other abnormal ndings involving organs beyond the spine. While spinal or vertebral pathologies can contribute the majority to LBP, they may not always be signicantly associated with it. As a result, MRI should not be the rst line of investigation for LBP. Instead, a comprehensive evaluation should be conducted to identify all possible pathologies. It is crucial to work closely with the patient's primary care physician to determine the most appropriate course of investigation and treatment for each case of low back pain.

Authors: Tatsuoka Tetsuro , Kawabata Shigenori , Hashimoto Jun , Hoshino Yuko , Shibuya Tomohiko , Adachi Yoshiaki , Okawa Atsushi
Published: May 2023

An adjustable helmet-style magnetoresistive (MR) sensor array, a room-temperature magnetic flux sensor, was developed to demonstrate simultaneous multipoint measurement of the somatosensory evoked magnetic field (SEF). The SEF was measured in three healthy subjects using an array of 30-channel MR sensors placed on the left hemisphere of the head with median nerve stimulation in the right wrist and averaged over 8,000 measurements. An M20 component (maximum amplitude of 725 ± 257 fT, peak latency of 20.5 ± 0.45 ms), considered to originate from the primary somatosensory cortex, was observed at an approximate latency of 20 ms of the magnetic field waveform in all cases. The phase inversion observed around C3 corresponded to the palmar area of the primary somatosensory cortex on the contour map of the magnetic field at the M20 peak. The MR sensor, a relatively inexpensive and easy-to-use magnetic sensor that does not require a zero-field environment, was successfully used for simultaneous multipoint SEF measurements in humans and may be a promising option to realize a reasonable magnetoencephalography application device.

Instability in the Centers of Radially Induced Subgraphs
Authors: Grassi Chris
Published: May 2023

Centrality measures identify vertices that are potentially important when compared to the rest of the graph. When applied to an induced subgraph for which all vertices are within a given radius of the center, we sometimes find the center of the subgraph is different. Here, we provide some insight into how these “fulcrum” points can arise in graphs, and show that the degree to which the center can change is generally unbounded.
Resilience-Oriented Extreme Weather Conditional Renewable Scenario Generation Based on Diffusion Models and Few-shot Learning
Authors: Zhu Yuhong , Zhou Yongzhi , Xia Yanghong , Wei Wei
Published: May 2023

Several natural disasters worldwide have demonstrated that the severity of extreme weather events (EWEs) on power systems can be increased by adversely affecting renewable power. Generating renewable scenarios specific to EWEs is crucial for the effective implementation of resilience-oriented operations and planning in power systems that incorporate a high proportion of renewable energies. Despite the significant progress achieved recently, it remains a formidable challenge to produce high-quality samples from a limited dataset due to the low occurrence probability of EWEs. A conditional diffusion model-based method is firstly introduced to discern spatiotemporal correlations of renewable series assoicated with common conditional like diurnal, season, and temperature without suffering from prevalent issues like statistical assumptions and mode collapse. To guarantee the specificity of the generated samples to EWEs while maintaining diversity, a fine-tuning mechanism is proposed for the pre-trained diffusion models using a few-shot learning technology in conjunction with a self-supervised loss function. The effectiveness of the proposed method is verified on two real-world dataset. Numerical results demonstrate that the scenarios generated by the proposed method exhibit distinct advantages in terms of diversity and EWE-specific consistency. This facilitates scenario-based two-stage robust optimization and enhances the performance of resilience-oriented decisions in out-of-sample scenarios.

Authors: Ladekar Ashvini , Takey Sristy , Nimbolkar Ujjawala , Nanaware Samruddhi
Published: May 2023

 A simple IOT-based soil and water testing system for evaluating the characteristics of arid soil was created. To track the changing soil quality and water availability while maximising water use effectiveness across the seasons, a sensor-based monitoring system with ethernet connectivity and mobile IoT is developed. This study is centred in the Indian state of Maharashtra, which is one of the major producers of oil and pulses and has a diversity of soil types. The primary crop that was taken into account was soybean because it is a crop that is widely grown in the area. Up until seed germination and roots, this crop was under observation. When compared to seeds produced using the traditional way of production, those produced using the IoT-based smart system were larger.  

Any automated irrigation system can benefit from this IOT-based monitoring system's assistance. This method makes it very simple to collect data, analyse that data, and use that understanding to distribute water without the need for manual labour.

Authors: Fahim Raouf Amir Hossein , Maeng Sung Joon , Guvenc Ismail , Ozdemir Ozgur , Sichitiu Mihail
Published: May 2023

The ever-growing demand for wireless connectivity, coupled with limited spectrum resources, has resulted in spectrum congestion and interference. This research investigates the probability of occupancy in common sub-6 GHz cellular network bands  based on measurements conducted in urban and rural environments. Specifically, we analyze the spectrum occupancy of various long-term evolution (LTE), 5th generation (5G) and Citizens Broadband Radio Service (CBRS) bands used in the United States, considering both uplink and downlink transmissions at altitudes up to 180 meters. Additionally, we explore the influence of altitude on the probability of spectrum occupancy in these bands.

Our findings reveal that the probability of occupancy is generally higher in the downlink compared to the uplink. Moreover, we observe that line-of-sight (LoS) signals play a critical role in higher altitudes. These results provide insights spectrum utilization in various cellular bands across different altitudes, with implications on  interference and spectrum coexistence between terrestrial networks and unmanned aerial systems (UASs) in the future.

Authors: Hancock Cody , Klement Peter , Schmeling Lucas , Hanke Benedikt , Maydell Karsten von
Published: May 2023

This publication devises a method which formulates a national strategy for the renovation of single family houses by treating each era of initial construction independent of all the others, and applies a universally adoptable procedure to evaluate the cost efficiency of carbon emission reduction. A multi-objective optimization was conducted which varied the building envelope and energy systems while optimizing for annual cost and carbon emissions. The optimization was carried out in oemof.solph and PyGMO on typical German building stocks from 11 different construction eras between 1860 and 2020. The buildings were modelled in TEASER using TABULA building stock data. The results indicate that post-war era construction has the greatest improvement potential by saving over 16 tons of CO2/yr with respect to its business as usual case.

Communication refers to the process of exchanging information between individuals, namely the sender and the receiver, with the aim of achieving mutual understanding. In an educational setting, communication strategies serve as a blueprint for how information is exchanged. In particular, the use of effective communication strategies by teachers is critical in constructing classroom discourse in English as a Foreign Language (EFL) classrooms. Such strategies and feedback from teachers are indispensable for students to enhance their abilities and performance in the classroom. Classroom discourse plays a vital role in the learning process, and teachers should consider it during the teaching and learning process. Consequently, this study aims to investigate the communication strategies utilized by teachers in constructing classroom discourse in EFL classrooms, as well as the types of feedback they employ to maintain interaction with their students during teaching and learning processes. To collect the required data, the researcher conducted qualitative descriptive research, using interview notes, note-taking, and observation. The participants were male and female English teachers who taught at different grade levels, including tenth and eleventh grades. The researcher interviewed English teachers regarding their communication strategies and the types of feedback they use during teaching and learning processes. The findings revealed that teachers employed five types of communication strategies, including literal translation, code-switching, nonverbal signals, fillers and hesitation-gambits, self and other-repetition, and appeals for help. The results indicate that the use of such strategies is effective in improving students' performance and ability in class. Additionally, the feedback that teachers use during teaching and learning processes can be categorized into two types, namely oral and visual feedback, which can be given on an individual or group basis.

SUSTAINABLE FINANCING AND ESG PRINCIPLES IN MULTILATERAL DEVELOPMENT BANKS
Authors:   Group B1-Consult, Moscow, Russia, Sunguryan Artem S.
Published: May 2023

Multilateral banks are the first institutional investors to use dedicated climate and financial finance. Raised through green, social and sustainability-linked bonds, these organizations are funding priority projects related to the energy transition, climate change mitigation and recovery, and develop social infrastructure. As interest in the above financial instruments has grown, Multilateral Development Banks have lost the lead to private financial and non-financial corporations, but are still innovators in the field of sustainable finance, as evidenced by the recent experience of the emerging blue finance. One of the problems of multilateral development banks in terms of sustainable financing is their strategic goal setting in this area. Focusing only on a quantitative indicator in the form of climate finance, as well as the lack of quantitative indicators in terms of the social sector in their strategies, do not allow us to assess the effectiveness of the measures taken by these institutions.

Abusive supervisory behaviour is a significant problem in today’s workplace that can have serious consequences for both employees and organisations. The purpose of this article is to provide a comprehensive review of research and theoretical work on the topic of abusive supervision by examining its manifestations, preconditions and consequences. The paper begins with a conceptualisation of the concept. It then discusses the factors that contribute to the emergence of hostile supervisory behaviour, such as organisational culture, personality traits and situational factors. It also examines the negative effects of this type of supervisor behaviour on employees, including decreased job satisfaction, increased stress and decreased work productivity, as well as consequences for organisations, such as increased employee turnover and reduced productivity.

The article discusses the main options for conducting competitive purchases within the framework of 44-FZ in terms of their advantages and disadvantages arising from the specifics of the purchase of insurance services. The main risks posed by the digitalization of procurement and the low insurance culture of the customer’s contract services are analyzed. Proposals are made on the need to introduce standardization of risks in terms of those types that are not covered by the legislation on compulsory insurance, for example, property insurance. The option of purchasing from a single supplier was considered separately from the point of view of transparency and expediency. Conclusions are drawn about the need to further reduce the options for purchasing insurance services and their standardization within the framework of 223-FZ.

Purpose: Gait changes are more prominently observed in older adults than in young adults, especially in kinematics of lower extremities and trunk. These changes can result in incidental falls during gait, possibly leading to inability to perform activities of daily living independently. This study aimed to investigate the effect of gender and age on gait changes, such as spatiotemporal parameters and peak joint angles in lower extremities and trunk during gait. Methods: A total of 387 participants (223 women) were included. The Microsoft Kinect V2 sensor was used to obtain the coordinate data of lower extremities and trunk during gait. The coordinate data obtained were processed using the software. Walking speed, stride length, stride time and cadence were calculated as spatiotemporal variables of walking. Forward trunk tilt angle (FTT), hip flexion and extension, and knee flexion and extension were measured as peak angles during one-gait cycle. Participants were categorized into five groups according to age by five years. Multivariate analysis of variance was performed to compare the spatiotemporal and kinematical data among groups. Results: Significant differences among age groups were noted in terms of the walking speed and stride length. Significant differences were also observed in the FTT and hip extension angle. Conclusions: Increased gait changes, increased peak FTT and decreased peak hip extension angle were observed with an increase of age. These altered symptoms may contribute to the screening of older adults at risk of declined physical function at an early stage

Purpose: The purpose of this work was to understand the biomechanical response and injury risk of thorax and abdomen of vehicle front seat occupants caused by seat belt load under different frontal crash pulses. Methods: A vehicle-seat-occupant subsystem finite element (FE) model was developed using the a assembly of vehicle front seat and seat belt together with the THUMS (Total Human body Model for Safety) AM50 (50th% Adult Male) occupant model. Then the typical vehicle frontal crash pulses from different impact scenarios were applied to the vehicle-seat-occupant subsystem FE model, and the predictions from the occupant model were analyzed. Results: The modeling results indicate that the maximum sternal compression of the occupant caused by seat belt load is not sensitive to the peek of the crash pulse but sensitive to the energy contained by the crash pulse in the phrase before seat belt load reaching its limit. Injury risk analysis implies that seat belt load of the four crash scenarios considered in the current work could induce a high thorax AIS2+ injury risk (>80%) to the occupants older than 70 years, and a potential injury risk to the spleen. Conclusions: The findings suggest that control of the energy in the first 75 ms of the crash pulse is crucial for vehicle safety design, and thorax tolerance of the older population and spleen injury prevention are the key considerations in developing of seat belt system.
