Using geochemical and pumping test data from 80 groundwater wells, the chemical, hydrologic, and hydraulic properties of the fractured Eocene carbonate aquifer located west of the Al-Minya district, the Western Desert, Egypt, have been characterized and determined to guarantee sustainable management of groundwater resources under large-scale desert reclamation projects. The hydrochemical data show that groundwater from the fractured Eocene carbonate aquifer has a high concentration of Na+ and Cl− and varies in salinity from 2176 to 2912 mg/L (brackish water). Water–rock interaction and ion exchange processes are the most dominant processes controlling groundwater composition. The carbonate aquifer exists under confined to semi-confined conditions, and the depth to groundwater increases eastward. From the potentiometric head data, deep-seated faults are the suggested pathways for gas-rich water ascending from the deep Nubian aquifer system into the overlying shallow carbonate aquifer. This mechanism enhances the dissolution and karstification of carbonate rocks, especially in the vicinity of faulted sites, and is supported by the significant loss of mud circulation during well drilling operations. The average estimated hydraulic parameters, based on the analysis of step-drawdown, long-duration pumping and recovery tests, indicate that the Eocene carbonate aquifer has a wide range of transmissivity (T) that is between 336.39 and 389,309.28 m2/d (average: 18,405.21 m2/d), hydraulic conductivity (K) between 1.31 and 1420.84 m/d (average: 70.29 m/d), and specific capacity (Sc) between 44.4 and 17,376.24 m2/d (average: 45.24 m2/d). On the other hand, the performance characteristics of drilled wells show that well efficiency ranges between 0.47 and 97.08%, and well losses range between 2.92 and 99.53%. In addition to variations in carbonate aquifer thickness and clay/shale content, the existence of strong karstification features, i.e., fissures, fractures or caverns, and solution cavities, in the Eocene carbonate aquifer are responsible for variability in the K and T values. The observed high well losses might be related to turbulent flow within and adjacent to the wells drilled in conductive fracture zones. The current approach can be further used to enhance local aquifer models and improve strategies for identifying the most productive zones in similar aquifer systems.

Published: September 2024

The enormous energy carried by discharged water poses a serious threat to the Piano Key Weir (PKW) and its downstream hydraulic structures. However, previous research on energy dissipation in PKWs has mainly focused downstream effects, and the research methods have been largely limited to physical model experiments. To deeply investigate the discharge capacity and hydraulic characteristics of PKW, this study established a PKW model with universally applicable geometric parameters. By combining physical model experiments and numerical simulations, the flow pattern of the PKW, the discharge at the overflow edges, and the variation in the energy dissipation were revealed for different water heads. The results showed that the discharge of the side wall constitutes the majority of the total discharge at low water heads, resulting in a relatively high overall discharge efficiency. As the water head increases, the proportion of discharge from the inlet and outlet keys increases, while the proportion from the side wall decreases. This change results in less discharge from the side wall and a consequent reduction in the overall discharge efficiency. The PKW exhibits superior energy dissipation efficiency under low water heads. However, this efficiency exhibits an inverse relationship with an increasing water head. The overall energy dissipation efficiency can reach 40% to 70%. Additionally, the collision of the water flows inside the outlet chamber and the mixing of the overflow jet play a primary role in energy dissipation. The findings of this study have significant implications for hydraulic engineering construction and PKW operational safety.

Published: September 2024

In the arid Arabian Peninsula, particularly within the United Arab Emirates (UAE), the perception of rainfall has shifted from a natural blessing to a significant challenge for infrastructure and community resilience. The unprecedented storm on 17 April 2024, exposed critical vulnerabilities in the UAE’s urban infrastructure and flood management practices, revealing substantial gaps in handling accumulated precipitation. This study addresses the necessity of updating the Intensity–Duration–Frequency (IDF) curves for the Sharjah Emirate by utilizing recent precipitation data from 2021 to April 2024, alongside previously published 2020 data. By recalibrating the IDF curves based on data from three meteorological stations, this study reveals a substantial increase in rainfall intensities across all durations and return periods. Rainfall intensities increased by an average of 36.76% in Sharjah, 26.52% in Al Dhaid, and 17.55% in Mleiha. These increases indicate a trend towards more severe and frequent rainfall events, emphasizing the urgent need to revise hydrological models and infrastructure designs to enhance flood resilience. This study contributes valuable insights for policymakers, urban planners, and disaster management authorities in the UAE and similar regions worldwide.
Hegemony and Colonialization in the Water Management Sector: Issues and Lessons for IWRM
Authors: Grigg Neil
Published: September 2024

Water resources management and the broad concept of Integrated Water Resources Management (IWRM) attract varied perspectives about their effectiveness and equity as they address diverse needs across sectors and contextual situations. Managers in the water sector generally support their current governance models, while anti-poverty advocates seek more equity in the distribution of resources. Another group of stakeholders claims a lack of inclusivity in decision-making, leading to inequitable outcomes due to hegemony and colonialization of the water management domain by sector experts, officials, and other actors. IWRM focuses on reforms in water governance to achieve greater participation and sharing of power by all sectors of society in decision-making. It can facilitate the involvement of all groups of stakeholders, including those who may in some cases need to engage in social action to address water issues. This paper reviews the claims about the validity of IWRM and analyzes them according to management scenarios where water is a connector among sector issues. The scenarios show that participation in utility and local government decisions is the main pathway for urban water, wastewater, and stormwater management, while the same pathway is more difficult to organize in dispersed situations for domestic supply and irrigation in rural areas, some cases of aquifer management, and management of sprawling flood risk zones. The body of knowledge about participation in water resources management is robust, but organizational and financial capacities among existing entities pose barriers. Water resources management and IWRM do involve hegemony, and the field of practice has been colonialized, but the existential issues and complexity of the decisions and systems involved challenge society to manage successfully while assuring equity and participation through governance reform. The debates over hegemony and colonialization in water management provide an opportunity to continue improving the norms of practice and water resources education.
Phytosorbents in Wastewater Treatment Technologies: Review
Authors: Vialkova Elena , Korshikova Elena , Fugaeva Anastasiya
Published: September 2024

Turning to green technologies in wastewater treatment is a well-known global trend. The use of natural sorbents of plant origin or phytosorbents in order to purify water from various types of pollutants is becoming more and more popular. This solves several important problems at once: the use of harmless natural materials, reducing the cost of processing, and waste disposal. Moreover, there is a global increase in waste in the agricultural, food, woodworking, and other industries. This review presents data on the modern use of natural materials, mainly vegetable waste, as sorbents in wastewater treatment technologies. Natural materials remove ion metals, dyes, crude oil and petroleum products, and other organic and non-organic contaminants. The techniques of obtaining phytosorbents from plant raw materials are considered. The methods for activation and modification of the various phytosorbents, which provide greater sorption efficiency, are presented. The adsorption mechanisms for various water contaminants are examined, and model descriptions are shown. It has been revealed that the effectiveness of sorption interaction mainly depends on the presence of functional groups. Studies over the past twenty years have shown good prospects for the use of such materials and technologies in practice.

Published: September 2024

This study investigated the efficacy of membrane bioreactor (MBR) technology in treating saline industrial wastewater, focusing on the impact of the organic loading rate (OLR) and the food-to-microorganism (F/M) ratio on treatment performance. This research utilized saline industrial wastewater from Al-Hasa, which had salinity levels ranging from 5000 to 6900 mg/L. It explored treatment processes at varying Chemical Oxygen Demand (COD) concentrations of 800, 1400, and 2000 mg/L, corresponding to an OLR of 0.80 ± 0.05, 1.41 ± 0.07, and 1.98 ± 0.12 g COD/L, respectively. The average F/M ratios used were 0.20, 0.36, and 0.50 g COD/g MLSS·d, maintaining a constant Sludge Residence Time (SRT) of 12 days, a hydraulic retention time (HRT) of 24 h (hrs.), and a flux of 10 L/m2·h. The MBR system demonstrated high COD removal efficiencies, averaging 95.7 ± 1.6%, 95.5 ± 0.4%, and 96.1 ± 0.3%, alongside Biochemical Oxygen Demand (BOD) removal rates of 98.3 ± 0.2%, 99.8 ± 0.1%, and 98.5 ± 0.1%, respectively. However, an increased OLR led to elevated residual COD and BOD levels in the treated effluent, with COD concentrations reaching 34.2 ± 12.8, 63.3 ± 5.9, and 76.5 ± 5.4 mg/L, respectively. This study also reveals a significant decline in ammonia and Total Kjeldahl Nitrogen (TKN) removal efficiencies as OLR increases, dropping from 96.1 ± 0.5% to 80.2 ± 0.9% for ammonia and from 83.8 ± 3.4% to 65.8 ± 2.3% for TKN. Furthermore, higher OLRs significantly contribute to membrane fouling and elevate the transmembrane pressure (TMP), indicating a direct correlation between OLRs and operational challenges in MBR systems. The findings suggest that for optimal performance within the Saudi disposal limits for industrial wastewater, the MBR system should operate at an F/M ratio of ≤0.33 g COD/g of Mixed Liquor Suspended Solid (MLSS)·d. This study underscores the critical role of the OLR and F/M ratio in treating saline industrial wastewater using MBR technology, providing valuable insights for enhancing treatment efficiency and compliance with environmental standards.

Published: September 2024

In recent decades, interest in gerontology has increased significantly. This is explained by the fact that among the most pressing problems facing the world community is the problem of population aging. As in many developed countries of the world, in Russia the number of people aged 80 years and older is increasing. The sharp aging of the population is the most important problem in the life of any state — that is why there is an urgent need to expand gerontological research. Target. Assessment of the existing system for placing elderly and senile people in a geriatric center (boarding house).Results. The working time costs of nursing staff were studied by conducting photo-timing and interviewing; an analysis of existing problems in the organization of nursing practice was carried out; real ways to improve the quality of life of an elderly person living in a boarding house are outlined. Conclusion. As sociological studies show, small boarding houses are indispensable in rural areas, where they take on the character of temporary institutions (for the autumn-winter period), largely solving the problems of many villagers who do not want to permanently move to boarding houses.

In modern obstetrics it is possible to regulate pain perception during childbirth. There are methods of both drug and non-drug pain relief during childbirth. Up to 25–30 % of women characterize labor pain as severe and excessive. Adequate labor pain relief provides psychological comfort and eliminates stress caused by pain. After labor pain, many women experience depression, decide to terminate the next pregnancy, or (up to 30 %) request a caesarean section without medical indications. Pain relief during labor is one of the priorities in obstetric care.

Authors: Yadav Pradhumna Kumar , Khizar Ahtesham , Bukhari Seeneen , Lamichane Somraj
Published: September 2024

Background: Calcified chronic subdural hematoma (CSDH) is unusual. The majority of calcified CSDHs are found near the convexity, and the amount of calcification varies greatly. The progression of calcification in a CSDH is unknown. Seizures, mental and physical impairment, hemiparesis, and gait abnormalities are some of the symptoms; nevertheless, some people are asymptomatic. Surgical intervention is preferred for a calcified CSDH that is expanding. However, there is no agreement on surgical therapy for asymptomatic calcified CSDHs.
Case Presentation: A 69-year-old man was reported to have had behavioural abnormalities and seizures in the past couple of years. He had a three-year history of minor head trauma. On clinical examination, he appeared confused and had no hemiparesis. His Computed Tomography (CT) brain revealed a calcified frontoparietal CSDH on the left side. A calcified CSDH was discovered in his brain by Magnetic Resonance Imaging (MRI) as well. This patient underwent a left-sided frontoparietal craniotomy, and the calcified CSDH was removed to the greatest extent possible. It was firmly attached to the underlying surface of the brain parenchyma. The postoperative period was straightforward, and the patient's behavioural alterations improved noticeably.
Conclusions: We described a patient who had a rare, persistent, calcified CSDH that was successfully removed, leading to a noticeable recovery. Based on our assessment of the literature and our patient's experience, we believe surgical treatment for calcified CSDH is viable and typically results in neurological improvement.

Authors: Gawad Kareem Abdel , Zidan Ashraf S. , Sabry Amin , Elsobky Hesham , Ramadan Mohamed
Published: September 2024

Background Data: Lumbar instability is considered an essential aetiology of low back pain (LBP) which is always accompanied by considerable disability.  The term ‘instability’ remains poorly defined. But it is most broadly explained by any change of the normal mechanism of spinal motion which leads to pain and/or neurological impairment. It was reported that ‘Segmental instability can be defined as a pathological reaction to the applied loads, characterized by motion in motion segments more than normal constraints. The dynamic system can stabilize an unstable segment adequately but permits more mobility in the fixed levels than the conventional fixation systems.
Study design: prospective, consecutive study
Patients and Methods: This study was conducted in Mansoura University hospitals over one year (starting from September 2019 till August 2020) Twenty patients who presented with back pain fulfilled our criteria and were included in this study and underwent surgery for lumbar fixation using a hybrid performance system with dynamic coupler. The history of all patients was taken and they were subjected to clinical examination and preoperative full radiological examination. Visual Analogue Scale (VAS) was used to evaluate POP. Regular follow-up visits were arranged for our cases 6 weeks, three months and 6 months postoperative.
Results: This study included  20 patients (7 males and 13 females). The ages of the studied patients ranged from 20 to 33 years. 9 patients presented with L4- 5 affection, 8 patients with L3- 4 affection and three patients with L2-3 affection. The mean basal VAS score was 5.45 (range=4-6) while the mean six months VAS score was 0.40 (range=0-1) with a statistically significant difference from the basal VAS score (p ? 0.001). Also, the results show that post-operative QoL scale scores was significantly higher (p? 0.001) compared with pre-operative QoL scale scores (Physical function (54.30 vs. 67.10), limitations due to physical health (55.55 vs. 67.90)).
Conclusion: The current study suggested that Dynamic lumbar fixation provides favourable and stable clinical mid-term results in patients suffering from a degenerative lumbar spinal disease (DLSD) and can be a considerable alternative to fusion surgery in these patients.

Authors: Kingston Mark , Snooks Helen , Watkins Alan , Burton Christopher , Dale Jeremy , Davies Jan , Dearden Alex , Evans Bridie , Santos Gomes Bárbara , Jones Jenna , Kumar Rashmi , Porter Alison , Sewell Bernadette , Wallace Emma
Published: September 2024

Background

Emergency admissions are costly, increasingly numerous, and associated with adverse patient outcomes. Policy responses have included the widespread introduction of emergency admission risk stratification (EARS) tools in primary care. These tools generate scores that predict patients’ risk of emergency hospital admission and can be used to support targeted approaches to improve care and reduce admissions. However, the impact of EARS is poorly understood and there may be unintended consequences.

Aim

To assess effects, mechanisms, costs, and patient and healthcare professionals’ views related to the introduction of EARS tools in England.

Design & setting

Quasi-experimental mixed-methods design using anonymised routine data and qualitative methods.

Method

We will apply multiple interrupted time-series analysis to data, aggregated at former clinical commissioning group (CCG) level, to look at changes in emergency admission and other healthcare use following EARS introduction across England. We will investigate GP decision making at practice level using linked general practice and secondary care data to compare case-mix, demographics, indicators of condition severity, and frailty associated with emergency admissions before and after EARS introduction. We will undertake interviews (approximately 48) with GPs and healthcare staff to understand how patient care may have changed. We will conduct focus groups (n= 2) and interviews (approximately 16) with patients to explore how they perceive that communication of individual risk scores might affect their experiences and health-seeking behaviours.

Conclusion

Findings will provide policymakers, healthcare professionals, and patients, with a better understanding of the effects, costs, and stakeholder perspectives related to the introduction of EARS tools.
POSITIONING THE WORKING ORGAN OF REHABILITATION SYSTEM IN THE PRESENCE OF HUMAN STUMP TREMOR
Authors: Berro Somar , Timofeev A. , Kochneva O.
Published: September 2024

The problem of accurate positioning of objects using an active prosthesis hand is not widely investigated, where many factors can play a significant role in degrading of the prosthesis accuracy. An unorthodox rehabilitation system equipped with manipulator with elastic links aimed to help people without brushes in performing fine tool movements has been developed. In this system, a force/torque sensor is securing a physical hard connection between the stump and the prosthesis. In such human-prosthesis systems many factors contribute to tool positioning error, but when high accuracy is required, the human tremor in the residual stump becomes a key factor affecting the accuracy of the tool fine movements. Mathematical model of this system is developed and the error resulted by stump tremor is isolated. Depending of the force/torque sensor, two control strategies are presented in order to perform high accuracy working organ movement between two points. The first is to use the sensor to collect involuntary stump movements caused by the tremor. The second is to use the sensor as an input for the control system by recording all stump movements. In computer simulation, the effect of three main types of human tremor on the manipulation accuracy of the rehabilitation system is observed. As a result, a positioning accuracy of 0.1 mm is achievable by meeting some design criteria that would element the resonance effect in the system
TECHNOLOGICAL APPROACHES TO IMPROVING THE QUALITY OF FINE-GRAIN CONCRETE
Authors: Murtazaev S-A.Yu. , Salamanova M.
Published: September 2024

The production of high quality and reliable fine-grained concrete using resource-saving technologies is a current and important task. The popularity of fine-grained concrete is determined by the possibility of eliminating coarse aggregate. It is expensive and in short supply in many regions of the country, and the ability to regulate within a wide range the structure and technical properties of the concrete mixture and concrete, by the quality of concreting of densely reinforced structures of complex configuration, increasing the impact strength of reinforced concrete elements. In this regard, to increase the demand for this product, research is carried out on the production of fine-grained concrete using locally available technogenic materials and technical methods based on established patterns of influence of recipe and technological parameters on physical, mechanical and operational characteristics. The lack of high-quality coarse sands in the region was a prerequisite for the search for new solutions to control the processes of contact formation between cement particles and fine aggregate. The recipe-technological method proposed in the work, which consists in the complex use of fractionated filler surface activated by the cationic additive of alkyldimethylbenzylammonium chloride, modified with microsilica binder, contributed to the enhancement of adhesive strength in the contact zone “cement stone-aggregate” and the formation of a dense structure composed of high-strength and poorly soluble formations. The proposed technology for producing fine-grained concrete will make it possible to create high-quality composites using technogenic raw materials, thereby solving the problem of the shortage of coarse natural sands suitable for construction.
AESTHETICAL MODELS OF INCLUSION RECOVERED INDUSTRIAL OBJECTS INTO EXSISTING URBAN STRUCTURE
Authors: Shein V.
Published: September 2024

The article presents models of aesthetic formation of reconstructed industrial objects of the Soviet period in the surrounding development in the context of sustainability at the level of the city structure, taking into account the growth of the urban fabric. The industrial enterprises in question, as a rule, initially located on the outskirts of the city. Due to the dynamics of urbanization processes, they have become tightly integrated into the urban fabric, and are currently so-called exclusion zones, since they are large-sized relative to the surrounding development objects, including residential buildings and elements of the infrastructure of its social and domestic services. It is also necessary to note the enterprises that are city-forming and located in the structure of the historical center of the urban settlement, where it is especially important to preserve the authenticity of the historical development: to introduce reconstructed industrial facilities as delicately as possible (to select the aesthetic model of the reconstructed enterprise) into the historically established visual and aesthetic code of the city. Thus, two models of aesthetic inclusion of existing industrial enterprises being restored into the city structure have been identified: mimicry, related to objects located in the historical part of the city, and accentual – forming a visual center of attraction outside the historical part of the city, on the periphery and outside the city. The article also examines options for aesthetic inclusion of industrial objects being reconstructed depending on their urban development features: the presence of buffer zones and sanitary protection zones, the presence of external railway routes adjacent to the objects

Authors: Oleynikov A. , Gnezdilov D.
Published: September 2024

With the development of modern digital technologies, many industries began to need the creation and development of tools for processing and systematization of information, their visual representation. In the architectural and urban planning sphere, digital technologies are reflected in the application of information modeling technologies (BIM modeling), which are effectively used in the design processes, during the construction of various facilities and their further operation. This study examines the effectiveness of the use of BIM technologies in the development of projects for the renovation and reconstruction of urbanized areas. Three-dimensional modeling of BIM technologies in renovation and reconstruction projects allows to simulate scenarios for the development of produced concepts and design solutions, assess the effectiveness of their impact on the territory, and predict their further development. Through the use of BIM technologies in renovation and reconstruction projects, it is possible to monitor the implementation of the developed solutions, monitor the current state of local facilities after their commissioning, identify and prevent the development of crisis situations. The authors have considered the definition of information modeling technology, and some basic ways of using BIM technologies are given. The main stages of work on the BIM model during renovation and reconstruction of the territory have been clarified and divided into four main stages. The first is the stage of collecting data on the existing situation; the second is the stage of building a model of the existing situation; the third is the stage of developing a project proposal for renovation and reconstruction and the forth is the stage of creating additional information models and detailed study of objects. Based on the analysis of the city of Belgorod, the need for renovation and reconstruction of the territory of the neighborhood "Savino" is justified, a project proposal for renovation and reconstruction using BIM technologies has been developed.

Published: September 2024

This study aims to relate how the Covid-19 pandemic affects social life, what kind of inequalities it creates, and how it affects existing social inequalities with the social class structure. In this context, the differentiation of the results of the pandemic according to class position has been problematized in the study, based on the daily life practices of individuals. In the literature review, it is seen that the social dimension of the Covid-19 pandemic is generally neglected. From this point of view, in this article, the social dimension of the pandemic has been discussed within the scope of class perspective. In this study, a total of 30 participants from different socioeconomic classes were interviewed using the semi-structured in-depth interview technique. In the interviews, it is understood that the main reason for the different experiences of individuals during the Covid-19 epidemic process is class differentiation. In the interviews conducted for this study, it was observed that individuals in the lower socioeconomic class experienced more income and job losses than other individuals, and therefore they faced more social risks. Considering the participants' experience of alternative working forms which was implemented in this period, it is one of the important findings that the participants in the lower socioeconomic class are the class with the least experience of alternative working styles, and accordingly, these individuals feel more insecure during the pandemic period. In the study, it is evaluated that the Covid-19 pandemic has increased the social inequalities that already exist in the society.

This study delves into the integration of the philosophical concepts of space and time within the context of Diriyah's rich cultural and historical backdrop, aiming to leverage these concepts as foundational pillars for innovative artistic design within the visual arts and design domain. It adopts a hybrid methodology that combines descriptive and analytical techniques for its theoretical framework with experimental approaches for practical application. The outcomes underscore the feasibility and potential of melding space and time philosophies to foster unique design ideas for installation art, thereby enriching the visual arts and design landscape. Some recommendations were presented including engaging deeply with philosophical themes such as the essence of space and time. This research not only contributes to the artistic valorization of Diriyah's heritage within the framework of Saudi Arabia's Vision 2030 but also propels forward the discourse on integrating architectural heritage with contemporary art practices.

Published: September 2024

The results of a study on modern instruments of science and innovation policy in foreign countries and Ukraine, based on research of publications by international organizations, government authorities of foreign countries, legal acts of Ukraine, and scientists, are presented. It has been identified that in many countries, there is a system of financial incentives aimed at accelerating research and development, innovations, expanding production, achieving environmental sustainability, and increasing employment. In Ukraine, legal documents mention various forms of state support for innovation, including (government funding programs, technoparks and innovation hubs, startup accelerators and incubators, investment funds and business angels, educational and research programs, tax incentives, international cooperation, etc.). However, the analysis revealed that in practice, tax incentives and benefits for R&D and innovation in Ukraine are implemented for a limited range of activities, such as aviation production and defense (during wartime), among others. It is concluded that there is a need for monitoring and evaluating the outcomes of implementing state support instruments for scientific and innovative activities to assess their relevance and effectiveness in Ukraine. The study is intended for government officials, experts, scientific and engineering staff, and faculty members of higher education institutions.
problemática da angústia em Freud
Authors: Moreira Jacqueline de Oliveira , Drawin Carlos Roberto
Published: September 2024

O presente artigo pretende tecer uma reflexão teórica histórica e crítica acerca das movimentações da problemática da angústia no texto freudiano. Não seguimos esse fio cronológico como se pudéssemos voltar no tempo para refazer o caminho do pensamento freudiano. Não há como retornar no tempo, e, sendo assim, todo retorno a Freud é uma reconstrução que utiliza materiais estranhos ao edifício original. Assim, primeiro, teceremos algumas considerações acerca das primeiras formulações freudianas sobre a angústia. Em seguida, a ideia é expor a inter-relação entre angústia e recalque. Por fim, assinalar as modificações introduzidas por Freud em seu último esforço de teorização sobre essa problemática atravessada pelo conceito de pulsão de morte.
que é uma pessoa?
Authors: Donati Pierpaolo
Published: September 2024

Margaret Archer aborda o conceito de pessoa humana no quadro da vexata quaestio das relações entre indivíduo e sociedade. Resumindo o problema: é a sociedade (formas sociais e instituições) que faz a pessoa humana ou é a pessoa que faz a sociedade? Esta questão dominou toda a teoria social desde o início da modernidade. Nas últimas décadas, o debate dividiu os acadêmicos entre aqueles inclinados a colocar em primeiro plano o livre agency da pessoa e aqueles que, em vez disso, deram o primeiro lugar às restrições das estruturas sociais; as duas soluções em certa medica foram mescladas, mas o resultado foi sempre um tanto nebuloso. A solução que Archer oferece é que nenhuma das respostas está correta, nem qualquer mescla das duas, porque elas não nos permitem compreender como ação e estrutura estão entrelaçadas. O desafio é compreender como e por que existe este emaranhado, ou melhor, vínculo, que preserva a autonomia tanto da pessoa (a sua liberdade) como das estruturas sociais (o seu poder condicionante), sem confundi-las.
UBERIZAÇÃO

Os avanços tecnológicos na sociedade do capital vêm possibilitando novas formas de exploração e mercantilização da força de trabalho através das plataformas digitais, afetando todas as dimensões da vida dos seres sociais. Atenta a estas novas morfologias, esta pesquisa tem como objetivo contribuir para a análise do fenômeno da Uberização a partir da compreensão de dois aspectos primordiais, quais sejam: como vem se dando o processo de reestruturação da atividade de trabalho na chamada Indústria 4.0, principalmente a dos motociclistas entregadores vinculados às empresas-aplicativo e quais são as determinações sociais implicadas neste processo. Para tanto, combinamos uma revisão de literatura sobre a categoria trabalho e a reestruturação das forças produtivas a partir de obras marxianas e análise de entrevistas semiestruturadas com entregadores de empresas-aplicativo na cidade de Belo Horizonte. Identificamos seis questões centrais: (i) a categoria trabalho continua sendo central para a existência e realização humana; (ii) a uberização não é um fenômeno disruptivo, sendo, na verdade, a apropriação, pelas empresas-aplicativo, por meio das plataformas digitais, da exploração da força de trabalho, utilizando-se destes novos recursos tecnológicos para aprofundar a precarização dentro da sociedade do capital.; (iii) o trabalho dos entregadores é controlado, gerenciado e fiscalizado através de algoritmos, restando evidente a subordinação destes às empresas-aplicativo; (iv) a intensificação da jornada e a negação da condição de assalariamento são os elementos centrais para a extração do mais-valor nesta forma de trabalho; (v) as condições socioeconômicas dos trabalhadores e as condições de empregabilidade são fatores determinantes para a entrada e permanência dos entregadores neste trabalho; (vi) mesmo reconhecendo certa autonomia, os entregadores se veem como superexplorados, precarizados e à margem das regulações legislativas e da proteção social. A partir disso concluímos que a uberização do trabalho é o reflexo de um capitalismo acentuadamente destrutivo, que vem se apropriando de uma massa de trabalhadores informais, utilizando-se das tecnologias mais avançadas, para acentuar ainda mais a superexploração da força de trabalho através de novas formas de controle e gestão, que ocultam a forma de trabalho assalariado, levando o trabalhador a se reconhecer como autônomo, enquanto que, em sua concretude, se mantém sendo trabalhadores informais, sendo subutilizados na medida das necessidades empresariais, ou seja do capital.

Published: September 2024

O surgimento da pandemia do COVID-19 alterou todos os aspectos da vida em sociedade. As instituições de ensino superior precisaram buscar formas de se adequar a essa nova realidade e, para isso, foi implementado o ensino remoto emergencial, uma modalidade de ensino na qual todas as atividades pedagógicas foram realizadas no formato remoto. Esta pesquisa foi desenvolvida com o objetivo de analisar como se deu a dinâmica de implementação do ensino remoto emergencial no curso de administração a partir da perspectiva dos integrantes do colegiado do curso, da chefia de departamento e da gestão da universidade. Para alcançar esse objetivo, utilizou-se a Teoria da Aprendizagem Situada e a Teoria da Aprendizagem Transformadora como abordagens teóricas. Foi realizado um estudo qualitativo básico, em que os sujeitos pesquisados foram os docentes integrantes do colegiado do curso de administração, a chefia do departamento didático-científico e a gestão da universidade, foi realizado também uma pesquisa documental com os documentos institucionais que se referiram à implementação do ensino remoto emergencial. A partir dos resultados observou-se como todo o processo de implementação do ensino remoto emergencial foi organizado na instituição estudada, identificando como se deu a comunicação entre todos os envolvidos e as consequências desse novo formato de ensino para os docentes e discentes.
