The Evolution of Climate Change Reporting in Business Media: Longitudinal Analysis of a Business Newspaper
Authors: Umamaheswaran Swarnalakshmi , Dar Vandita , Thaker Jagadish
Published: November 2022

The agenda-setting and attitude-forming role of media has been proven and endorsed over time. Media has played an instrumental role in the way the issue of climate change is perceived by various stakeholders in society. Although studies on media coverage of climate issues have been gaining prominence in recent years, there is a gap when we consider the Global South. Moreover, although the business sector is a critical stakeholder in climate change policy and action, studies that focus on how business media projects and highlights climate change are relatively sparse. This vacuum is even more pronounced in developing countries. This research is an attempt to address this gap. We have conducted a longitudinal analysis of climate change reporting in a leading Indian business newspaper, using automated content analysis. Results provide us with valuable insights about how climate frames and climate themes have evolved over time in business media. Our findings suggest that while climate cooperation is a prominent topic in business media, however, it has been declining in recent years. On the other hand, the share of domestic news covering sector specific issues is increasing, mirroring India’s change in stance. The insights derived will help in building consensus across stakeholders involving business decision-makers, media houses, policy makers, and civil society.
Examining Students’ Readiness toward Using Learning Management System at University of Ha’il: A Structural Equation Modelling Approach
Authors: Alshammari Mohammed Habib , Alshammari Sultan Hammad
Published: November 2022

During the past two decades, many universities around the world have deployed various types of learning management systems (LMSs) to manage the learning and teaching process electronically. The rapid spread of the coronavirus disease at the start of the COVID-19 pandemic quickened educational systems’ shifting from face-to-face to online instruction. Blackboard is the most used LMS during this transition in Saudi Arabian universities, institutions, and higher education institutions. Although previous research has widely investigated students’ adoption of Blackboard, few studies have examined the factors affecting their readiness toward e-learning. The present study used the model of Student Online Learning Readiness (SOLR) as the primary framework for examining the factors that may affect students’ readiness toward using Blackboard. A survey was delivered to undergraduate and postgraduate students at the University of Ha’il to collect data, and a total of 196 responses were received. A two-step process in AMOS was applied to analyse the data. The study findings showed that technical, social, and communication competencies had a significant positive influence on the readiness of students toward using Blackboard LMS. The study outcomes will provide educators, designers, decision-makers, and practitioners with a deeper understanding of the factors that could influence students’ readiness toward using Blackboard and, thus, enhance the successful usage of the system.

Published: November 2022

The precise assessment of environmental risks is significant in the transformation from treatment after pollution towards a precaution and management regime. Herein, we employed the linear combination of the Analytic Hierarchy Process (AHP) and Entropy-Weighted (EW) method to exam the impacts of 14 environmental risk factors of 70 enterprises in Lanzhou against the Yellow River aquatic safety. The results showed that enterprises that present a low-risk level to the aquatic safety of the Yellow River accounted for 73% of enterprises, and 27% of enterprises presented a medium level of risk. No enterprise presenting a high level of risk was found. In each administrative district/county, the total value of environmental risks in the Honggu, Xigu, and Anning Districts came to 22.87, 40.51, and 14.17, respectively, due to these districts being the location of a massive number of industries. Furthermore, this study found that the types of enterprises, the species of the risk substance, the shortest distance from the Yellow River, the river′s level, and the population density were the main contributors to the environmental risks. Other issues, such as weak outfall supervision and the shortage of emergency supplies also require increased attention.

Published: November 2022

In developing countries, motorcycle riders normally attempt to stop at their desired locations during queue formation on signalized intersection approaches. Under mixed-traffic conditions, motorcycle positioning in a queue affects the operational and safety performance of the intersection. This study aimed to identify factors influencing motorcycle riders’ stopping locations at signalized urban intersections. This study applied Unmanned Aerial Vehicles (UAVs) to observe the stopping behavior of 1413 motorcycle riders on 24 approaches from 10 signalized intersections in Thailand (N = 1413). Multinomial logistic regression analysis was used to determine the relationship between the stopping locations of motorcycle riders and rider- and motorcycle-related variables and traffic- and environmental-related variables. The statistical analyses presented a Cox and Snell R2 and Nagelkerke R2 of 0.466 and 0.499, respectively, indicating that the model accounted for almost 50% of the variation among the five stopping locations of motorcycle riders. The results showed that, under mixed-traffic conditions in Thailand with left-hand traffic, motorcycle riders intending to turn right, the morning peak period, the presence of shadows, motorcycle riders not wearing helmets, the presence of a larger vehicle in the queue, and the density of desired stopping locations significantly influenced the motorcyclists’ choice of stopping locations on signalized intersection approaches. Practical policy-related recommendations drawn from the findings are provided to improve motorcyclists’ safety on signalized intersection approaches.
A Further Study on the Degree-Corrected Spectral Clustering under Spectral Graph Theory
Authors: Liu Fangmeng , Li Wei , Zhong Yiwen
Published: November 2022

Spectral clustering algorithms are often used to find clusters in the community detection problem. Recently, a degree-corrected spectral clustering algorithm was proposed. However, it is only used for partitioning graphs which are generated from stochastic blockmodels. This paper studies the degree-corrected spectral clustering algorithm based on the spectral graph theory and shows that it gives a good approximation of the optimal clustering for a wide class of graphs. Moreover, we also give theoretical support for finding an appropriate degree-correction. Several numerical experiments for community detection are conducted in this paper to evaluate our method.
Analytical View of Nonlinear Delay Differential Equations Using Sawi Iterative Scheme
Authors: Nadeem Muhammad , Edalatpanah Seyyed Ahmad , Mahariq Ibrahim , Aly Wael Hosny Fouad
Published: November 2022

This paper presents the idea of the Sawi iterative scheme (SIS) to derive the analytical solution of nonlinear delay differential equations (DDEqs). We apply the Sawi transform to construct a recurrence relation which is now easy to handle and the implementation of homotopy perturbation method (HPM) reduces the nonlinear components to obtain a series solution. This series is independent of any assumption and restriction of variables that may ruin the actual problem. A transformation that keeps the differential equations consistent is known as a differential equation symmetry. It is very simple and easy to obtain the solution of these differential equations in the presence of such symmetries. We deal with this approach in a very simple way and obtain the results in the form of convergence. We also demonstrate the graphical solution to show that this approach is very authentic and valid for linear and nonlinear problems.
A New Look at Physico-Chemical Causes of Changing Climate: Is the Seasonal Variation in Seawater Temperature a Significant Factor in Establishing the Partial Pressure of Carbon Dioxide in the Earth’s Atmosphere?
Authors: Kennedy Ivan , Runcie John , Zhang Shuo , Ritchie Raymond
Published: November 2022

Seasonal oscillations in the partial pressure of carbon dioxide (pCO2) in the Earth’s atmosphere, stronger in northern latitudes, are assumed to show that terrestrial photosynthesis exceeds respiration in summer, reducing the pCO2 in air but increasing its value in winter when respiration exceeds photosynthesis. We disagree, proposing that variation in the temperature of the surface mixing zone of seawater also reversibly regulates the pCO2 in air as a non-equilibrium process between air and seawater. We predict by thermal modelling that carbonate (CO32−) concentration in the surface mixed layer seawater declines in winter by conversion to bicarbonate with CaCO3 (calcite or aragonite) becoming more soluble and, proportional to the fall of temperature, calcite decalcifying more strongly, allowing more CO2 emission to air. Paradoxically, the increasing CO2 concentration in seawater favoring photosynthesis peaking in mid-summer declines simultaneously in autumn and early winter, forced by boundary layer fugacity into phase transfer to the atmosphere, supporting peak atmospheric pCO2 by late winter. These physico-chemical processes reverse in late winter and spring as seawater warms favoring calcification, fugacity forcing CO2 from the atmosphere as bicarbonate declines and carbonate increases, augmenting suspended calcite particles by several percent. Our numerical computation predicts that the larger range of thermal fluctuations in the northern hemisphere could reversibly favor absorption from air of more than one mole of CO2 per square meter in summer with calcite formation potentially augmenting shallow limestone reefs, despite falling pH, if there is a trend for increasing seawater temperature. Another assumption we challenge is that upwelling and advection from deeper water is the sole cause of increases in dissolved inorganic carbon (DIC) and alkalinity in surface waters, even in the southern hemisphere. Instead, some calcite dissolution is favored as water temperature falls near the surface. Standard enthalpy analysis of key DIC reactions indicates why this oscillation is more obvious in the northern hemisphere with seasonal variations in water temperature (ca. 7.1 °C) being almost twice those in the southern hemisphere (ca. 4.7 °C) with a greater depth of the surface mixing zone of seawater in the southern oceans. Questions remain regarding the relative rates of biotic and abiotic inorganic precipitation and dissolution of CaCO3 in the mixing zone. In summary, rapid biogenic calcification is favored by summer photosynthesis, but slower abiotic calcification is also more likely in warmer water. We conclude that the relative significance of terrestrial biotic and seawater abiotic processes in seawater on the seasonal oscillation in the atmosphere can only be assessed by direct seasonal measurements in seawater.
Small Peptides in the Detection of Mycotoxins and Their Potential Applications in Mycotoxin Removal
Authors: Zhao Zitong , Zhang Zhenzhen , Zhang Haoxiang , Liang Zhihong
Published: November 2022

Mycotoxins pose significant risks to humans and livestock. In addition, contaminated food- and feedstuffs can only be discarded, leading to increased economic losses and potential ecological pollution. Mycotoxin removal and real-time toxin level monitoring are effective approaches to solve this problem. As a hot research hotspot, small peptides derived from phage display peptide libraries, combinatorial peptide libraries, and rational design approaches can act as coating antigens, competitive antigens, and anti-immune complexes in immunoassays for the detection of mycotoxins. Furthermore, as a potential approach to mycotoxin degradation, small peptides can mimic the natural enzyme catalytic site to construct artificial enzymes containing oxidoreductases, hydrolase, and lyase activities. In summary, with the advantages of mature synthesis protocols, diverse structures, and excellent biocompatibility, also sharing their chemical structure with natural proteins, small peptides are widely used for mycotoxin detection and artificial enzyme construction, which have promising applications in mycotoxin degradation. This paper mainly reviews the advances of small peptides in the detection of mycotoxins, the construction of peptide-based artificial enzymes, and their potential applications in mycotoxin control.

Like the world over, Nepal was also hard hit by the second wave of COVID-19. We audited the clinical care provided to COVID-19 patients admitted from April to June 2021 in a tertiary care hospital of Nepal. This was a cohort study using routinely collected hospital data. There were 620 patients, and most (458, 74%) had severe illness. The majority (600, 97%) of the patients were eligible for admission as per national guidelines. Laboratory tests helping to predict the outcome of COVID-19, such as D-dimer and C-reactive protein, were missing in about 25% of patients. Nearly all (>95%) patients with severe disease received corticosteroids, anticoagulants and oxygen. The use of remdesivir was low (22%). About 70% of the patients received antibiotics. Hospital exit outcomes of most (>95%) patients with mild and moderate illness were favorable (alive and discharged). Among patients with severe illness, about 25% died and 4% were critically ill, needing further referral. This is the first study from Nepal to audit and document COVID-19 clinical care provision in a tertiary care hospital, thus filling the evidence gap in this area from resource-limited settings. Adherence to admission guidelines was excellent. Laboratory testing, access to essential drugs and data management needs to be improved.

Virus-based biopharmaceutical products are used in clinical applications such as vaccines, gene therapy, and immunotherapy. However, their manufacturing remains a challenge, hampered by the lack of appropriate analytical tools for purification monitoring or characterization of the final product. This paper describes the implementation of a highly sensitive method, capillary electrophoresis (CE)-sodium dodecyl sulfate (SDS) combined with a laser-induced fluorescence (LIF) detector to monitor the impact of various bioprocess steps on the quality of different viral vectors. The fluorescence labelling procedure uses the (3-(2-furoyl) quinoline-2-carboxaldehyde dye, and the CE-SDS LIF method enables the evaluation of in-process besides final product samples. This method outperforms other analytical methods, such as SDS–polyacrylamide gel electrophoresis with Sypro Ruby staining, in terms of sensitivity, resolution, and high-throughput capability. Notably, this CE-SDS LIF method was also successfully implemented to characterize enveloped viruses such as Maraba virus and lentivirus, whose development as biopharmaceuticals is now restricted by the lack of suitable analytical tools. This method was also qualified for quantification of rAAV2 according to the International Council for Harmonisation guidelines. Overall, our work shows that CE-SDS LIF is a precise and sensitive analytical platform for in-process sample analysis and quantification of different virus-based targets, with a great potential for application in biomanufacturing.
Generation of a Live-Attenuated Strain of Chikungunya Virus from an Indian Isolate for Vaccine Development
Authors: Nair Sreeja R. , Abraham Rachy , Sreekumar Easwaran
Published: November 2022

Chikungunya virus (CHIKV) re-emergence in the last decade has resulted in explosive epidemics. Along with the classical symptoms of fever and debilitating arthralgia, there were occurrences of unusual clinical presentations such as neurovirulence and mortality. These generated a renewed global interest to develop prophylactic vaccines. Here, using the classical approach of virus attenuation, we developed an attenuated CHIKV strain (RGCB355/KL08-p75) for the purpose. Repeated passaging (75 times) of a local clinical isolate of ECSA lineage virus in U-87 MG human astrocytoma cells, an interferon-response-deficient cell line, resulted in efficient adaptation and attenuation. While experimental infection of 3-day old CHIKV-susceptible BALB/c pups with the parent strain RGCB355/KL08-p4 resulted in death of all the animals, there was 100% survival in mice infected with the attenuated p75. In adult, immunocompetent, CHIKV-non-susceptible C57BL/6 mice, inoculation with p75 induced high antibody response without any signs of disease. Both p4 and p75 strains are uniformly lethal to interferon-response-deficient AG129 mice. Passive protection studies in AG129 mice using immune serum against p75 resulted in complete survival. Whole-genome sequencing identified novel mutations that might be responsible for virus attenuation. Our results establish the usefulness of RGCB355/KL08-p75 as a strain for vaccine development against chikungunya.

Dengue fever is one of the significant fatal mosquito-borne viral diseases and is considered to be a worldwide problem. Aedes mosquito is responsible for transmitting various serotypes of dengue viruses to humans. Dengue incidence has developed prominently throughout the world in the last ten years. The exact number of dengue cases is underestimated, whereas plenty of cases are misdiagnosed as alternative febrile sicknesses. There is an estimation that about 390 million dengue cases occur annually. Dengue fever encompasses a wide range of clinical presentations, usually with undefinable clinical progression and outcome. The diagnosis of dengue depends on serology tests, molecular diagnostic methods, and antigen detection tests. The therapeutic approach relies completely on supplemental drugs, which is far from the real approach. Vaccines for dengue disease are in various stages of development. The commercial formulation Dengvaxia (CYD-TDV) is accessible and developed by Sanofi Pasteur. The vaccine candidate Dengvaxia was inefficient in liberating a stabilized immune reaction toward different serotypes (1–4) of dengue fever. Numerous promising vaccine candidates are now being developed in preclinical and clinical stages even though different serotypes of DENV exist that worsen the situation for a vaccine to be equally effective for all serotypes. Thus, the development of an efficient dengue fever vaccine candidate requires time. Effective dengue fever management can be a multidisciplinary challenge, involving international cooperation from diverse perspectives and expertise to resolve this global concern.

Published: November 2022

Vaginal myiasis is one of the most serious parasitic diseases in Bactrian camels. At present, there are no reports on biological control measures of the disease. In this paper, the metabolomic analysis of vaginal secretions from susceptible and non-susceptible camels was performed by ACQUITY UPLC H-Class Ultra Performance Liquid Chromatograph. The results matched in 140 vaginal compounds. Methylheptenone, 1-octen-3-ol, and propyl butyrate and their mixtures were selected for gas chromatography-electroantennography (GC-EAD), electroantennography (EAG), behavioral experiments and trapping experiments of Wohlfahrtia magnifica (W. magnifica). Results showed that the W. magnifica had EAG responses to the three compounds, respectively. The EAG responses of female flies to different concentrations of methylheptenone were significantly different, but to the others had no significant difference, and there was no significant difference in the same compounds between the different sexes. Behavioral and trapping experiments showed that methylheptenone and 1-octen-3-ol have significant attraction to W. magnifica, but there was no significant difference to propyl butyrate. When methylheptenone and 1-octen-3-ol were mixed in different proportions, it was found that a mixture at the ratio of 1:1 and 0.5:1 had extremely significant and significant attraction, respectively, to both male and female W. magnifica. The study showed that, except for propyl butyrate, the higher the concentrations of the other two compounds, the stronger the attractivity to the W. magnifica, and a mixture at the ratio of 1:1 could enhance the attractivity to the W. magnifica.

The case study presented in the paper is the first in the field to find microplastic (MP) particles in both grey water (GW) and post-treatment sewage (TS) samples, which can also be legally discharged into specially protected areas. Compiling a data set of 50 water samples collected from the GW and TS samples of 5 transport ships involved in the case study, we show that the mean number of separated microparticles in the GW samples n = 72 particles per litre, and in the TS samples n = 51 particles per litre. Of the 614 separated particles, the most common were fibres n = 285 (46.4%), followed by other (various) hard particles n = 226 (36.8%) and soft particles n = 104 (16.8%). Attenuated total reflectance Fourier transform infrared spectroscopy (ATR FT-IR) identification was mainly in the form polyethylene (PE), polypropylene (PP) (solid particles and films), polyesters, polyamides, and acrylic fibres. Scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) analysis revealed ecotoxic chemical elements on the surface of these particles. Our results show that the sewage treatment facilities installed on ships need to be improved, and we developed a solution for this. The findings of the case study certainly deserve further attention and serve as an impetus for research on the improvement of ship wastewater treatment facilities.

Published: November 2022

Intensity–duration–frequency (IDF) curves are widely used in the hydrological design of hydraulic structures. This paper presents a wide review of methodologies for constructing IDF curves with a specific focus on the choice of the dataset type, highlighting the main characteristics, possible uncertainties, and benefits that can be derived from their application. A number of studies based on updating IDFs in relation to climate change are analyzed. The research was based on a comprehensive analysis of more than 100 scientific papers and reports, of which 80 were found to be suitable for the aim of this study. To classify the articles, the key was mainly intensity–duration–frequency curves in relation to the types of datasets most used for their construction, specific attention was paid to the case study area. The paper aims to answer the following research questions. (i) What is the contribution of a data-rich era? (ii) Are remotely sensed data reliable to build IDFs in ungauged or partially gauged watersheds? (ii) How is uncertainty dealt with when developing IDFs? Remotely sensed data appear to be an alternative to rain-gauge data in scarcely gauged or ungauged areas; however, rain-gauge data are still a preferred dataset in the development of IDFs. The main aim of the present work is to provide an overview of the state of the art on the use of different types of data to build IDFs. The paper is intended to support the inclusion of different data types in hydrological applications.

Published: November 2022

Rivers are dynamic geological agents on the earth which transport the weathered materials of the continent to the sea. Estimation of suspended sediment yield (SSY) is essential for management, planning, and designing in any river basin system. Estimation of SSY is critical due to its complex nonlinear processes, which are not captured by conventional regression methods. Rainfall, temperature, water discharge, SSY, rock type, relief, and catchment area data of 11 gauging stations were utilized to develop robust artificial intelligence (AI), similar to an artificial-neural-network (ANN)-based model for SSY prediction. The developed highly generalized global single ANN model using a large amount of data was applied at individual gauging stations for SSY prediction in the Mahanadi River basin, which is one of India’s largest peninsular rivers. It appeared that the proposed ANN model had the lowest root-mean-squared error (0.0089) and mean absolute error (0.0029) along with the highest coefficient of correlation (0.867) values among all comparative models (sediment rating curve and multiple linear regression). The ANN provided the best accuracy at Tikarapara among all stations. The ANN model was the most suitable substitute over other comparative models for SSY prediction. It was also noticed that the developed ANN model using the combined data of eleven stations performed better at Tikarapara than the other ANN which was developed using data from Tikarapara only. These approaches are suggested for SSY prediction in river basin systems due to their ease of implementation and better performance.

Interest in using various nanoparticle catalysts to activate H2O2 with light for organic contaminant and wastewater treatment is steadily increasing. We successfully synthesized magnetically recoverable Cu0.5Mn0.5Fe2O4 nanoparticles using a simple co-precipitation method followed by melamine-assisted calcination. Material characterization revealed that melamine acted as a coordinating agent during the calcination process that promoted a ferrite structure. Copper (Cu)-substitution effectively decreased material aggregation and promoted catalytic activities. Cu0.5Mn0.5Fe2O4 nanoparticles showed outstanding catalytic performance on several organic contaminants (87.6–100.0% removal within 2 h). Using oxytetracycline (OTC) as a surrogate wastewater constituent, we found that the hydroxyl radical (•OH) and superoxide anions (•O2−) were the active radical species involved in OTC degradation. Cu0.5Mn0.5Fe2O4 nanoparticles exhibited excellent photo-Fenton catalytic ability in real wastewater and demonstrated high material stability, even after four consecutive uses (i.e., fourth cycle). In a pilot-scale experiment (10 L), we provide proof that our rigorous treatment system was able to remove remnant OTC, TOC, and also any available colloidal particles to only 1 NTU. Ecotoxicity studies using an aquatic plant (Hydrilla verticillata) and zooplankton revealed that treated water could be reused in various ratios. Furthermore, at 5% of treated water, rapid leaf recovery and a significant increase in rotifer numbers were reported. These observations support the use of Cu0.5Mn0.5Fe2O4/H2O2/light as an efficient and environmentally friendly catalytic system for treatment of organic contaminants, and a radical generating mechanism is proposed.
The Impact of Water Temperature on In-Line Turbidity Detection
Authors: Shi Meixia , Ma Jingbo , Zhang Kai
Published: November 2022

Turbidity measurements are influenced by environmental factors such as water temperature. We designed experiments to study whether water temperature affects in-line turbidity detection and the potential influence mechanism. A turbidity meter installed in-line could self-record data, including the water temperature and turbidity values. From our experimental analysis, we verified the influence of water temperature on the in-line turbidity. Moreover, the temperature coefficient should not be obtained from the experiment directly because the intrinsic impact of in-line turbidity detection does not come from water temperature. Instead, the effect is derived from the optical components’ heat change. When the water temperature change is insignificant, the in-line turbidity deviation caused by the water temperature can be ignored. However, when the water temperature changes substantially, the in-line turbidity sensor should compensate for the temperature drift.

Fundamentos filosóficos e praxiológicos da meditação vipassana de Mahasi Sayadaw (1904-1982) e S. N. Goenka (1924-2013) e suas raízes no budismo Theravada
Authors:   , Vieira Otávio Augusto Diniz
Published: November 2022

A presente tese tem por objetivo apresentar a genealogia histórica das escolas contemporâneas do Movimento Vipassana, surgidas no século XIX no sudeste asiático, mais especificamente em Mianmar, e investigar os fundamentos filosóficos e praxiológicos de duas das mais reconhecidas dessas escolas e seus respectivos métodos, a saber, a escola de Mahāsī Sayādaw (1904-1982) e a escola de S. N. Goenka (1924-2013) e suas respectivas literaturas. Mais especificamente, a tese trata dos fundamentos canônicos dessas duas escolas de meditação, com foco na tripartição disciplinar da “virtude” (sīla), “concentração” (samatha) e “sabedoria analítica” (vipassanā), cujas fontes canônicas são o Mahāsatipaṭṭhāna Sutta – O Grande Sutras dos Fundamentos da Consciência Plena, e o tratado Visuddhimagga – O Caminho da Purificação, de Buddhaghosa. Na investigação dos dois métodos discutem-se seus fundamentos filosóficos e praxiológicos, suas estruturas disciplinares representadas pelos retiros, pelas práticas cotidianas e pela relação mestre-discípulo/professor-aluno, e as continuidades e descontinuidades com relação aos mestres predecessores e com a tradição Theravāda como um todo.
O conceito de exterioridade: constantemente referido à pseudonímia kierkegaardiana
Authors:   , Lopes Paulo Henrique da Silva
Published: November 2022

A Modernidade pode ser entendida pelo processo de interiorização do fundamento metafísico para o âmbito do sujeito de tal modo que a interioridade moderna, sob o mote da autenticidade e da autonomia, pode se tornar um essencialismo. Ao produzir subjetividades fechadas sobre si mesmas, esta atomização ontológica contribui para o afloramento de problemas como o relativismo, o subjetivismo e o individualismo. Esta tese mostrará que a superação destes problemas não pode se dar em se apelando para mediações universais e objetivantes – que chamaremos de externalidades –, mas em se promovendo o exílio radical do fundamento metafísico do âmbito do sujeito – que chamaremos exterioridade. Para tanto, identificamos que, já no século XIX, a obra kierkegaardiana se apresenta como uma precursora deste exílio ontológico que tomará força principalmente com o pós-estruturalismo francês do século XX e suas discussões sobre alteridade. Desde a sua pseudonímia, e apelando a um paradigma protestante para promover tal exílio ontológico, a obra kierkegaardiana desautoriza Kierkegaard (19813 – 1955) enquanto autor moderno, ao mesmo tempo em que performa a desconstrução daquela interioridade do sujeito moderno enquanto fundamento ontológico de sua própria individualidade. Isto quer dizer que, a partir deste exílio, o indivíduo torna um si mesmo não mais por um processo de autoconhecimento de sua voz interior, mas da resposta a uma convocação exterior ao exercício de si mesmo. É neste contexto que a presente tese proporá o conceito de exterioridade, referindo-se constantemente à pseudonímia kierkegaardiana para discutir as implicações existenciais e, sobretudo, éticas deste exílio ontológico. Pois quando o indivíduo e a multidão deixam de ser o critério para o próprio devir, aqueles problemas modernos podem ser encaminhados: a tautologia moderna se esgota em um paradoxo. Uma vez que a relação com esta exterioridade radical demanda uma relação que foge da mediação logocêntrica, o devir se torna, portanto, uma questão que compete à religião – um outro paradigma de subjetividade, menos autoritário, é colocado. Por isso mesmo, por depender de um critério radicalmente fora dos limites da especulação, o conceito de exterioridade mostra a sua relevância para a delimitação epistemológica de nossa área: o conceito de exterioridade é um dos poucos que é próprio do estudo pela Ciência da Religião.
Modelagem de técnicas de controle populacional do mosquito Aedes aegypti
Authors:   , Silva Monalisa Reis da
Published: November 2022

O mosquito Aedes aegypti é o principal vetor transmissor de várias doenças como dengue, zika, chikungunya e febre amarela. Dentro estas, a dengue se espalhou mais rapidamente no mundo, nos últimos 50 anos. Seu controle requer um melhor entendimento da dinâmica populacional espacial do mosquito, incluindo seu ciclo de vida. A maioria dos modelos descreve a dinâmica da população total dos mosquitos com um número grande de parâmetros indefinidos. Esta abordagem não nos permite tratar aspectos topográficos e espaciais do Aedes aegypti, importantes do ponto de vista da saúde pública. Nesta tese foi modelada a dinâmica populacional espacial do mosquito Aedes aegypti usando equações diferenciais parciais. Foi apresentada uma modelagem que descreve o fenômeno de maneira satisfatória minimizando o número de variáveis e parâmetros. Mostrou-se como estimar os valores destes parâmetros a partir de dados experimentais encontrados na literatura, usando conceitos de sistemas dinâmicos e equações diferenciais parciais. O modelo desenvolvido foi aplicado em três estudos comparando os casos homogêneos (os valores dos parâmetros não dependem da topografia) e heterogêneos (alguns valores dos parâmetros mudam com a topografia, i.e., diferenciam ruas, casas e parques). São muitos os fatores que influenciam na disseminação do vetor transmissor da dengue. São apresentados resultados que evidenciam a importância de se considerar a dependência da temperatura na simulação da dinâmica populacional do Aedes aegypti. A abordagem por EDOs permite uma aplicação, uma vez que a partir de dados experimentais sobre um número máximo de mosquitos em cada fase é possível estimar a capacidade suporte da fase aquática. É apresentada uma análise sobre a frequência para a utilização de duas técnicas de controle do mosquito Aedes aegypti. No contexto das análises feitas, é possível inferir sobre a periodicidade mais eficaz de cada técnica de controle. Dessa forma, é possível adequar às formas de combate de acordo com a situação de disseminação do vetor, possibilitando aos órgãos públicos um planejamento de estratégias de prevenção e combate
Investigação estrutural e aplicações de silicatos lamelares do tipo Magadiita a partir de cálculos ab initio baseados na DFT.

A Na-Magadiita (Na2Si14O28(OH)2·8H2O) é um silicato lamelar hidratado formada por lamelas de siloxanos (SiO4) e silanóis/silanolatos (SiO3OH/SiO3O - ) neutralizadas por cátions de sódio hexacoordenados com moléculas de água. Este sólido é muito conhecido por produzir materiais modificados para uso em adsorventes de gases poluentes e/ou catalisadores. Sua estrutura passou muito tempo sem elucidação estrutural e várias propostas foram, sem sucesso, sugeridas na literatura. Assim, o objetivo principal desta tese é apresentar a investigação estrutural Na-magadiita, descrita recentemente através do refinamento de Rietveld da difração de elétrons 3D aliado aos cálculos DFT apresentados neste trabalho. A estrutura do refinamento experimental foi otimizada em suas geometrias, mantendo o padrão de picos principais no DRX. A região interlamelar mostrou duas posições de águas (axiais e equatoriais) coordenadas ao sódio, com ligações de hidrogênio com os oxigênios da lamela de 1,8 Å e 2,0 Å, respectivamente, e interações distintas confirmadas pela densidade de carga. Espectros simulados de RMNES corroboraram os dados experimentais quanto aos sítios Q3 (- 95,0 ppm) e Q4 (-105,0 a -114,0 ppm) para o núcleo de 29Si, sinal de geometria octaédrica (0,0 ppm) no núcleo 23Na, e sinais relativos à água (3,0 a 10,0 ppm) diferenciados dos grupos silanol (15,0 ppm) no núcleo 1H. Em seguida, foram realizadas análises termodinâmicas de três etapas de calcinação deste sólido. A desidratação da região interlamelar mostrou duas curvas distintas para Gibbs, em que ΔGº < 0 kJ.mol-1 com a saída de H2O axial a partir de 32 ºC, enquanto ΔGº < 0 kJ.mol-1 para moléculas de H2O equatorial a partir de 150 ºC. Para ambas, as curvas de entalpia mostraram reações endotérmicas. Na segunda etapa, a curva de Gibbs sugeriu que o silicato de sódio zeolítico é termodinamicamente mais favorável em relação à zeólita Si14O28 durante a condensação das lamelas. As etapas finais mostraram ΔGº < 0 kJ.mol-1 para formar silicato de sódio e quartzo. Na última parte, foram avaliados os modelos de troca catiônica: K-, Ca- e Mg-magadiita. A região interlamelar de cada material otimizado mostrou comportamento de águas semelhantes à forma sódica, reproduzindo mesmo padrão de picos de DRX em 25º – 30º em 2θ. Cátions bivalentes apresentaram maior interação água-lamela e menor comprimento de ligação coordenada, comparado a K+ e Na+ . Bandas distintas relativo aos movimentos de águas equatoriais e axiais no infravermelho sugeriram que, nas isotermas de adsorção experimentais, as primeiras coordenações ao redor do cátion desidratado acontecem em águas axiais e, somente após o preenchimento da esfera de hidratação, posições equatoriais são identificadas na estrutural final.
A verdade da existência na existência da verdade: a epistemologia paradoxal-amorosa de Kierkegaard
Authors:   , Oliveira Fernanda Maria Leite Winter de
Published: November 2022

Esta tese tem como objetivo situar o problema epistemológico em Kierkegaard como um problema existencial-amoroso. Iremos, especialmente através das obras do pseudônimo Johannes Climacus, explorar as noções de conhecimento e verdade, as quais nos fornecerão a estrutura da epistemologia kierkegaardiana. Apontaremos a partir disso duas dimensões epistemológicas: uma negativa, que afirma a impossibilidade do conhecimento; e uma paradoxal, que afirma a possibilidade do conhecimento. Veremos que a segunda dimensão remete ao que Climacus denomina nas Migalhas Filosóficas de Paradoxo Absoluto e que apenas na relação com esse paradoxo é possível ao indivíduo colocar-se numa relação com a verdade. Climacus ainda nos apontará, através de seu PósEscrito, o aspecto subjetivo dessa relação. É apenas com as obras de Anti-Climacus, contudo, que esse conhecimento nos será apresentado como uma relação dinâmica e viva, a qual engloba, mas ao mesmo tempo transborda, seu aspecto cognitivo. Por fim, buscaremos através de uma obra não-pseudônima, As Obras do Amor, compreender em que sentido essa relação transborda o cognitivo e revela uma dimensão não apenas subjetiva, mas também intersubjetiva quando compreendemos esse conhecimento paradoxal como conhecimento amoroso
Fronteiras e abismos: a ficção realista em Jimmy Corrigan
Authors:   , Costa Bernard Martoni Mansur Corrêa da
Published: November 2022

Este texto propõe um estudo da estética realista na história em quadrinho Jimmy Corrigan: o menino mais esperto do mundo (2009), do autor estadunidense Chris Ware. A tese se fundamenta em um olhar atento e interessado, uma análise das escolhas estéticas que caracterizam essa HQ de Ware. O trabalho pode ser lido em duas questões centrais que se atravessam ao longo do texto. Uma delas trata de uma melhor compreensão dos conceitos, discussões e percepções em torno do termo “realismo” nas histórias em quadrinhos e de seus desdobramentos dentro dos processos narrativos. Outra busca compreender como a história em quadrinho de Chris Ware se estabelece como uma ficção realista. Desse modo, recorri a teóricos que discutem a narrativa e suas manifestações realistas; textos a respeito do histórico e linguagem das histórias em quadrinhos; obras dedicadas ao trabalho e processos criativos de Chris Ware. Também são trazidas ao texto diversas narrativas em quadrinhos de autores estadunidenses, bem com alguns canadenses, pelo diálogo estético dessas publicações com o trabalho de Ware.

Published: November 2022

O presente artigo falará dos direitos humanos e a segurança pública: suas prioridades e conflitos. O objetivo do artigo é delimitar os ramos dos direitos humanos aplicáveis a segurança pública, apresentado de forma coerente e coesa os conflitos entre direitos fundamentais no procedimento policial brasileiro. Tendo inspiração nos princípios constitucionais, em tratados internacionais, ser policial não é unicamente um trabalho é estabelecer a ordem pública, garantir a dignidade da pessoa humana, as liberdades e direitos essenciais, proporcionando a paz na sociedade, é manter manter um Estado Democrático de Direito embasado no desenvolvimento da sociedade, acesso absoluto à justiça e proteção aos direitos sociais e individuais. Justifica-se na segurança pública relacionada às políticas públicas, seja nas suas proposições, na avaliação de suas particularidades, por ser obrigação coletiva constituida de estrutura e base de sustentação. O estudo trata-se de uma revisão integrativa de literatura, cujo método visa agrupar de maneira sistemática e abrangente os resultados atualizados, incluindo todos os tipos de metodologias.  A dignidade do homem o possibilita a fazer tudo o que a lei não proíbe, diante de uma sociedade complexa que aciona as polícias para desfazer uma situação delituosa coletiva ou individual. E os políciais agem embasados nas legislações, na Constituição e nos direitos humanos. Garantindo que a lei seja aplicada e os direitos das pessoas sejam respeitados, estes esforços contribuem e se revelam instrumentos de uma nova mentalidade voltada para a polícia mais proxima da comunidade, com ênfase na atividade preventiva e ao mesmo tempo proativa.
