Precarização e empreendedorismo: o trabalho dos entregadores das plataformas digitais
Authors: Silva Elayne Cristina Menezes
Published: September 2024

O presente trabalho parte da realidade concreta do capitalismo contemporâneo, ao observarmos a disseminação do discurso do empreendedorismo permeando a publicidade das plataformas digitais – aplicativos de entregas – destinadas aos trabalhadores entregadores, numa reflexão teórica sobre a precarização do trabalho. A precarização do trabalho evidencia-se como dinâmica predominante desde a década de 1970 no Brasil, em resposta à crise estrutural do capital. As novas expressões da classe trabalhadora estão cada vez mais atreladas aos serviços, e o trabalho, a única mercadoria do trabalhador, permanece subjugado na era digital, na compressão do tempo via aceleração do trabalho. O controle do capital se reforça e se reproduz com a ideia de que os trabalhadores estão se autogerindo, são empreendedores e trabalhadores livres. Entretanto, as plataformas fixam frequentemente o preço do serviço, bem como definem os termos e condições do serviço, ou permitem aos clientes definir os termos (mas não ao trabalhador). Na perspectiva do materialismo histórico e dialético, a pesquisa ressalta a realidade dos entregadores dos aplicativos, no entendimento que ao invés de estarem a serviço do bem-estar social, as tecnologias digitais reforçam o caráter instrumental e opressor da lógica do modo capitalista de produção, reduzindo o trabalhador na exata medida das demandas do capital. O propósito do presente artigo é suscitar algumas reflexões sobre a condição do empreendedor individual e a desrealização do trabalho humano subjugado à ordem capitalista como caracterização do novo proletariado de serviços na era digital.

O arranjo espacial de plantas na cultura da soja, tem sido foco de diversos estudos que visam o aumento da produtividade, maior eficiência no uso da área e o maior retorno econômico da cultura. Dessa forma, o objetivo deste trabalho foi avaliar três arranjos espaciais de plantas (convencional, plantio cruzado e espaçamento reduzido), de maneira a identificar o que proporciona maior retorno econômico. O estudo de campo foi conduzido em área comercial de 100 hectares no município de Alto Garças, MT, por cinco safras consecutivas (2014/2015, 2015/2016, 2016/2017, 2017/2018 e 2018/2019), com alternância dos arranjos espaciais, em sistema de plantio direto. O arranjo convencional da soja mostrou-se cerca de 35% mais rentável que os demais. Os arranjos que utilizaram maiores populações de plantas (plantio cruzado e espaçamento reduzido) apresentaram menores produtividades de grãos e maiores custos efetivos e operacionais, além de baixa receita e índice de lucratividade negativo. A semeadura convencional garantiu menores custos, maior rendimento de grãos e maiores índices de lucratividade, que foramsuperiores de 30%. As características custo, produtividade de grãos de soja e preço médio pago na saca de soja possibilitam a predição da viabilidade econômica da soja na região estudada. Concluiu-se que o arranjo convencional apresenta maior produtividade, rentabilidade, lucratividade e melhor relação custo/benefício nas condições em que o estudo foi realizado.

The continued increase of spam and fake information in the digital age has raised serious concerns about the veracity and authenticity of digital content. To tackle this issue, we have developed a unified machine learning-based classification system thatdistinguishes between spam, fake, and legitimate information, addressing a gap in existing solutions which typically focuses either on spam or on fake information only. In this research, we collected a diverse dataset which includes both data from YouTube spam collection, email and SMS spam databases, as well as fake news from the some of the largest fake news datasets available—WELFake fake news dataset and GossipCop fake news dataset. Our approach underwent preprocessing and feature extraction steps and thereafter the implementation of different machine learning models like logistic regression, k-Nearest Neighbors, XGBoost, Extra Trees Classifier, andRandom Forest. The performance of these models, were examined using various performance metrics like accuracy, precision, recall and F1 Score. Result: the best-performing model, with the most optimal results was Extra Trees Classifier among the baseline models followed by XGBoost and Random Forest, and the Voting Classification significantly improved the accuracy of these baseline models. This unified approach offers a comprehensive solution for automating the filtering of digital content, substantially enhancing the reliability of information by simultaneously addressing multiple types of misinformation.

Authors: Ayala-Chauvin Manuel , Avilés-Castillo Fátima
Published: September 2024

In the last decade, the advancement of artificial intelligence has transformed multiple sectors, with natural language processing standing out as one of the most dynamic and promising areas. This study focused on comparing the GPT-3.5, GPT-4 and GPT-4o language models, evaluating their efficiency and performance in Natural Language Processing tasks such as text generation, machine translation and sentiment analysis. Using a controlled experimental design, the response speed and quality of the outputs generated by each model were measured. The results showed that GPT-4o significantly outperforms GPT-4 in terms of speed, completing tasks 25% faster in text generation and 20% faster in translation. In sentiment analysis, GPT-4o was 30% faster than GPT-4. Additionally, analysis of response quality, assessed using human reviews, showed that while GPT-3.5 delivers fast and consistent responses, GPT-4 and GPT-4o produce higher quality and more de-tailed content. The findings suggest that GPT-4o is ideal for applications that require speed and consistency, while GPT-4, although slower, might be preferred in contexts where text accuracy and quality are important. This study highlights the need to balance efficiency and quality in the selection of language models and suggests implementing additional automatic evaluations in future research to complement the current findings

Study’s Excerpt

Hepatotoxic effects of amlodipine is evaluated in Wistar rats.
The research identifies mild degenerative changes in heart tissues and inflammatory responses in liver tissues at higher doses.
Safety evaluations of antihypertensive medications is recommended.

Full Abstract
There is a high prevalence of premature deaths worldwide because of hypertension, a common condition that greatly raises the risk of heart disease, brain abnormalities, and renal malfunction. Reaching more than a billion people worldwide, low- and middle-income nations are the main areas where the illness is found. In order to lessen vascular smooth muscle contraction and increase vasodilation, amlodipine, a drug often used for hypertension, inhibits L-type calcium channels. Daily use is appropriate due to its extended half-life and excellent bioavailability. This study looks at how amlodipine affects the liver and cardiac tissues of Wistar rats from a histological, biochemical, and physical perspective. For the duration of the trial, a standard pellet diet and water were provided to the control group (Group A, n = 4) of the twenty rats utilised in this study. The drug was administered using a 0-10µl micropipette with appropriate tips, and an oral gavage was used to ensure accurate delivery into the animals' mouths. This study found significant dose-dependent increases in liver enzyme levels (p<0.05) in the treatment groups compared to the control, indicative of potential liver toxicity indicative of potential liver toxicity. Histological analysis showed normal heart tissue at lower doses but mild degenerative changes at higher doses. Liver tissues exhibited minor inflammatory responses at higher doses. These findings emphasize the importance of ongoing safety assessments for antihypertensive medications to ensure their long-term safety.

Authors: tej Gonuguntla Varun , Khalid Amnah , Perwaiz Muhammad
Published: September 2024

Foreign Body (FB) aspiration incidence follows a bimodal distribution and is commonly seen in children under the age of 5 or adults with advanced age. The type of FB can be organic or non-organic and varies depending on age, region of the world, and socioeconomic status. In children, FB aspiration is often a consequence of development and exploration. Aspiration of FB in adults typically occurs when cough reflex is blunted due to altered sensorium (from drugs, medications, advanced age), trauma to the airway, poor swallowing, or anatomical variations in the GI tract (strictures, Zenker’s Diverticulum, etc. Symptoms can range from cough to asphyxiation depending on the acuity of the aspiration event. Initial management is focused on ensuring there is no airway compromise leading to respiratory failure. Bronchoscopy is the treatment of choice to retrieve the FB. This chapter will review the incidence of FB aspiration in children vs. adults and will focus on diagnosis and treatment including bronchoscopy, role of ECMO, and surgical intervention.
Downhole Steam Generation for Heavy Oil and Oil Sands Production
Authors: B. Hytken Kent
Published: September 2024

Steam injection lowers the viscosity of heavy oil and oil sands trapped in underground formations. Steam injection is one of the most reliable thermal-enhanced oil recovery methods for heat introduction. Conventional steam applications generate steam from an inefficient high-pressure boiler, which has significant heat losses, degradation in steam quality, and uncertainty in steam distribution in the reservoir while emitting greenhouse gas emissions into the environment. In contrast to the high-pressure steam boiler, a downhole steam generator provides a step-change improvement with immense potential to produce heavy oil below 2500 ft., which can be a transformative thermal-enhanced oil recovery method and pave the way for an exciting advancement.

Authors: Albertus Jan-Willem Vos M.
Published: September 2024

The subfamily Caesalpinioideae contains 5096 accepted species and 519 unplaced species according to the World Flora Online (WFO) Plant List. For the past 10 years, we have experimented with 585 taxa of Acacias and other Caesalpinioideae. These seeds have very similar germination profiles. While there has been extensive research, especially in Australia, we have only found 173 research papers for 319 taxa. Upon the time of writing, we have done 1,754 experiments. This paper proposes a return to our experiments especially for species without any known research. Our methods are based on nursery work in view of planting in the botanical garden of Château Pérouse. For this to work, we have developed a range of tools in order to create microclimates as well as substrates for the nursery and the garden. These also give the possibility of testing the response to climate change in the garden.
A Quantum Leap for Waste and BECCS with B-VM Power Plant
Authors: Boeckmann Hubert
Published: September 2024

This chapter details the development of a so-called B-VM power plant from a patented bioenergy process B-V. The objective is the valorization of municipal waste and the implementation of an upstream waste system for the B-V to process the delivered waste. Intermediate products of the B-VM process are storable pyrolysis coke, pyrolysis oil and synthesis gas which generate electrical and thermal energy. A portion of this energy is used to extract carbon dioxide from the process emissions for realizing BECCS (Bioenergy with Carbon Capture and Storage). Compared to the combustion of waste or biomass, the following ecological and economic benefits and innovations are achieved: Optimal valorization of residual waste and biomass; decoupling of thermal and electrical energy production; doubling of the net electric efficiency of the power plant; potential to achieve negative emissions through BECCS; capable for base and peak load and also very strong grid balancing.
A Computational Study of Structure, Dynamics, and Spectral Properties of Ionic Liquids: Wavelet Spectra as a Tool to Assess Microscopic Dynamics of Ionic Liquids
Authors: Biswas Aritri , S. Mallik Bhabani
Published: September 2024

This perspective summarizes the recent advances in modeling ionic liquids to highlight structural as well as dynamical aspects and spectroscopic investigations in complex ionic environments. Wavelet transform serves as a valuable tool for spectral analysis in these liquids. The wavelet spectra obtained from this transform are found to be compared with the results of the conventional Fourier methods. The merit of the wavelet transform method representing the vibrational stretch spectral signature depends on the flexible intermolecular potentials. Wavelet transform is an effective tool for calculating frequency fluctuations based on molecular dynamics simulations. Here, we emphasize the methodology of calculating wavelet spectra based on trajectories derived from computer simulations, aiding a molecular-level interpretation that correlates experimental results satisfactorily.
Role of Microorganisms in Seed Germination
Authors: C. Garg Faquir
Published: September 2024

Quality of the seed, the backbone of modern agriculture, is an important factor in the successful establishment and performance of any crop. Two indicators of seed quality are uniform seed germination and seedling vigour. To enhance germination, many types of treatments, including beneficial microbes belonging to arbuscular mycorrhizal fungi, Trichoderma spp., rhizobia and other bacteria, have been tried on seeds before sowing via coating or bio-priming treatments and increase in seed germination of different crops including cereal crops, oil seeds and vegetables, have been reported. The role of endophytes and seed-borne microorganisms on seed germination and the mechanism of action of microorganisms in seed germination have also been discussed.
Pest Management in Sub-Saharan Africa: Mitigating the Challenges of Insecticides Use
Authors: Asamani Ebenezer , Asalma Nboyine Jerry , Quandahor Peter , Agrengsore Philip , Adomako Joseph
Published: September 2024

Intensification of agricultural production practices has led to monocultures of crop varieties over large areas of land. This has elevated many insects to economic pests’ status. In these systems, farmers typically rely on insecticides to mitigate the damaging effects of insect pests. Although all insecticides have negative human and environmental health consequences when applied, the severity of the impact differs depending on the toxicity of their technical compound and on its formulation. Thus, the World Health Organization (WHO) recognizes five insecticide classes: (Ia) extremely hazardous, (Ib) highly hazardous, (II) moderately hazardous, (III) slightly hazardous and (U) unlikely to present an acute hazard. In African agriculture, farmers’ choice of insecticides to mitigate pest damage is based on efficacy and cost. This often leads to the purchase of cheap insecticides, the majority of which are classified as extremely or highly hazardous. This chapter therefore discusses the different systems of pesticide classification, why pesticides are needed in agriculture and assesses the justification for insecticide use in selected major crops. It further examines the effects of insecticides on natural enemies of pest species and on human health. Finally, the chapter discusses sustainable methods to mitigate the negative effects of insecticide use in smallholder crop production systems.
Insecticides: Treatment and Resistance in Insects
Authors: Singh Akanksha , Pande Himanshu , Kumar Gaurava
Published: September 2024

Insects are the most successful group of creatures, thriving in any habitat. Insect pests can have far-reaching consequences, such as destroying crops that are essential food supplies for humans and livestock. Insecticides are essential in modern-day agriculture; besides being effective as a crop safety measure, they can also prove beneficial in preventing the spread of hazardous pests that can cause human diseases. Because of economic and medicinal reasons, developing potent and efficient pest control chemicals is a critical challenge in agrochemical research and the industrial sector as well. In this chapter, we are concerned about the exorbitant use of insecticides and their negative impacts on agriculture and so on the environment as well. Excessive pesticide treatment can contribute to the development of resistance in target insects, requiring larger concentrations or stronger chemicals, raising production costs, and disrupting natural pest control systems. Consequently, non-target animals, such as beneficial insects and aquatic life, suffer the inadvertent outcomes of insecticide use, resulting in ecosystem disparities and possible food chain pollution. This section offers a valuable understanding of merging present-day advances in science and practical applications, insect pest management approaches, and the promise of greater resilience and sustainability in agriculture.
Long-term floodplain vegetation dynamics after a permanent water level regulation
Authors: Odland Arvid
Published: September 2024

This chapter is a review of studies on vegetation dynamics on a freshwater delta ecosystem after a permanent water level drawdown. Floodplain wetlands are globally threatened and have long been recognized as sensitive to changes in the hydrological regime. The original floodplain vegetation types were left “hanging” over the new water level, and secondary successions were immediately initiated both in the original vegetation and on the newly exposed sediments. Permanent transects were established running from the original vegetation toward the new water’s edge. Repeated analyses were conducted to document plant dynamics over a period of 33 years. The focus has been to analyze the dynamics of the decomposition of the original vegetation, the development of new vegetation on exposed sediments, and the varying fertility of plants. The plants’ responses are discussed in relation to effects of important environmental factors and why the original vegetation has not been reestablished after the regulation.
Using Educational Robotics (ER) to promote STEM Problem-solving in Preservice Teachers
Authors: Jaipal-Jamani Kamini
Published: September 2024

With the recent emphasis on learning STEM skills across the k-12 curriculum globally, there is need to provide elementary preservice teachers (PTs) with knowledge of what STEM skills are and how to teach STEM problem-solving skills. In many k-12 curricula, the teaching of STEM skills is mainly incorporated into the science and mathematics curricula. The literature suggests that educational robotics (ER) is an instructional activity that can support school students learn STEM skills. This chapter reports on a study that explored how middle school PTs engaged in STEM problem-solving during a robotics activity. A qualitative, comparative case study design was employed. Data sources included a problem-solving worksheet, audio-recordings of group interactions, and video-recordings or photographs of artifacts. The discourse of six PT groups was analyzed using a STEM problem-solving framework. The results provide insights into the STEM problem-solving decisions of PTs during these ER activities such as PTs drawing on mainly everyday, practical experiences and some basic STEM knowledge to frame and plan the problem, and solving through trial-error-trial feedback loops. Recommendations are made for enhancing PTs STEM problem-solving and the design and implementation of ER activities for elementary students.
The Role of Pre-Desert Vegetation in the Rehabilitation of Degraded Soil
Authors: Hamida Mallem
Published: September 2024

In arid and Saharan zones, drought and human activities accentuate the risk of degradation of pre-desert rangelands. Some plants disappear, while others persist and adapt. In this study, we aimed to list the plants that can grow in a sandy environment and investigate their distribution levels and effect on sand dunes. We conducted vegetation inventories in Laghouat province in Algeria, and we calculated the ecological parameters using the transect method. The height of fixed windblown deposits was measured under all inventoried plants. Under three perennial plants (Retama raetam, Aristida pungens, and Astragalus armatus), soil texture, and physical and microbiological characteristics were analyzed. We found that the area studied is species-poor but has certain diversity, so the plant biological type influenced sand fixation. Fixed Aeolian deposits stabilized by plants ranged in height from 28 to 63 cm. Micro-dunes stabilized by R. raetam exhibited higher nitrogen, carbon, and bacterial richness compared to those stabilized by A. pungens. In contrast, A. pungens micro-dunes had greater calcium carbonate, electrical conductivity, and fungal richness. Our findings highlight the distinct contributions of each species to soil rehabilitation. Moreover, the complementary effects of these plants suggest their potential for synergistic wind erosion control.

Published: September 2024

An advanced waste management system has been developed specifically for high-rise residential buildings, aiming to achieve zero-food waste emissions through efficient biomass recovery. In response to the global trend of increasing high-rise construction, this system includes two main components: a food waste cutting and transfer device installed under household sinks, and a centralized automatic module located in the building’s basement. The system efficiently handles solid-liquid separation, dehydration, and bio-drying, converting food waste into high-quality biomass with low moisture content that is suitable for long-term storage. Fully automated and equipped with remote monitoring capabilities, the system ensures a sanitary and convenient environment for residents. Successfully implemented in two large-scale apartment complexes in Korea, it has operated seamlessly for over three years without causing any inconvenience to residents. Additionally, the system has encouraged greater resident participation in sustainable waste management practices, such as the separation of recyclable and special wastes in communal sorting rooms. The implementation of this integrated system is proposed as a viable technical solution for sustainable waste management in high-rise buildings, aligning with global trends in eco-friendly urban development and addressing the challenges posed by climate change.

Authors: Yosimar Jaen-Cuellar Arturo , Alejandro Elvira-Ortiz David , Gustavo Manriquez-Padilla Carlos , Cueva-Perez Isaias , Perez-Cruz Angel , Jose Saucedo-Dorantes Juan
Published: September 2024

Currently, postgraduate students have greater difficulty in the problems they must solve during the development of their projects since more specialized strategies are required to provide an adequate solution. Because the basic tools that they learned during the degree are no longer sufficient to solve the complexity that arises from these problems, it is necessary to rethink the way in which they approach them, and to allow them, through review and feedback cycles, to evaluate whether their procedure is correct. Therefore, this chapter presents a strategy based on the appropriate design of flowcharts that allow the student to divide a complex engineering problem into stages that are easier to work on, while allowing them to organize their times and manage them. Likewise, this strategy will serve as a generalized tool to be applied to any engineering problem. A case study is presented in which the flowchart design strategy is applied and validated through simulated tests and real experimentation.

Background: Asthma is the most common chronic non-communicable disease in children and one of the most common in adults, and the majority of asthma-related deaths are attributed to middle- and low-income countries. Physicians’ knowledge and practice have been recognized as fundamental elements in the approach to the asthmatic patient with an impact on the treatment and control of the disease. This study aimed to assess the knowledge and practice of Angolan physicians in the management of asthma, as well as to identify the main gaps. Methods: It was a cross-sectional study carried out in Angola. The data were collected through an online questionnaire to assess the knowledge about asthma among the physicians and the Physicians Practice Assessment Questionnaire. Categorical variables were described with frequencies and percentages. All associations between good practice and possible predictors were established with logistic regression analysis. P<0.05 was considered statistically significant. Results: A total of 204 physicians throughout Angola participated; the majority of whom were female, aged ­between 31 and 40, and from the Luanda province. The average percentage of correct answers for all domains was 65.8% (±SD11.1%). The lowest percentages were in the answers about the diagnosis, drugs, and the signs of an asthma attack. Out of the 204 participants, 81.9% of physicians confirmed seeing patients with asthma. The average percentage of them who reported practicing asthma management based on recommended guidelines was 59.8% (±SD27.8%). More than half of the physicians did not achieve that percentage. The lowest percentages of correct answers concerned assessment of the inhaler technique, provision of a written referral for asthma education, and use of the GINA guidelines to assess the patient’s asthma control. Concerning the predictors of best practices, our results showed that being a physician of older age and with more work experience, as well as having the category of specialist were significant predictors of adherence to recommended practices for asthma management. Conclusions: The physicians’ level of knowledge about asthma was moderate, but there are important practical gaps in asthma management regarding standard guidelines.

Unintelligent Ingenium: The Failure of Ingenium in Intelligent Design
Authors: Temple Nicholas ,   Pennsylvania Communication Association
Published: September 2024

Intelligent Design provides scholars with a very recent case study of an attempt to once again utilize such a conceptual framework, but in this case the rhetoric of the framework seems to be failing. A rhetorical examination of how and why the rhetoric of ID is proving ineffective is thus in order and should prove of interest to rhetorical scholars examining other similar movements to rhetor-ically unite religion and science.
“Even with the Professors it’s Expected”: An Analysis of College Students’ Discussion of Campus Drinking Culture
Authors: King Mary E. , La Valley Angela G. ,   Pennsylvania Communication Association
Published: September 2024

Underage and dangerous drinking on college campuses is a prevalent concern for universities and individuals. We conducted four focus groups with a total of 20 undergraduate students and asked them questions about their college drinking and alcohol experiences. Specifically, our study highlights the narratives and unique experiences of undergraduates in a public university. This research sought to identify themes related to student perceptions of drinking on campus. A content analysis of the focus group transcripts identified nine themes related to students’ experience and discussion of alcohol. Our findings are consistent with previ-ous research that suggests the culture of drinking on college campuses is influenced by multiple sources and affects various individuals and communities. We make recommendations that future research should aim to establish programing to benefit students and foster faculty education.
Just Keep Dancing: Reclaiming African American Identity through Dance Performance
Authors: De Jesus Marquita ,   Pennsylvania Communication Association
Published: September 2024

Dance as a form of communication in marginalized communities recognizes the degree to which the body is both implicated in the reproduction of trauma and also a meaningful site for embodied activism. While dance is both art and rigorous physical activity, it also develops psychological reasoning abilities that allow the dancer to use performance opportunities to internally and exter-nally reason, express, and transmute marginalizing experiences. Dance as a form of embodied activism works to support change in the relational fabric of experiences so that structural shifts correspond with authentic transformations in attitude that allow for self-definition and somatic reclamation. This paper explores the ways in which African Americans have and continue to crea-tively use embodied practices to reclaim identity, re-imagine body stories, and access to new futures through dance performance.
