Demand Estimation Under Uncertain Consideration Sets
Authors: Jagabathula Srikanth , Mitrofanov Dmitry , Vulcano Gustavo
Published: September 2023

In “Demand Estimation Under Uncertain Consideration Sets,” Jagabathula, Mitrofanov, and Vulcano investigate statistical properties of the consider-then-choose (CTC) models, which gained recent attention in the operations literature as an alternative to the classical random utility (RUM) models. The general class of CTC models is defined by a general joint distribution over ranking lists and consideration sets. Starting from the important result that the CTC and RUM classes are equivalent in terms of explanatory power, the authors characterize conditions under which CTC models become identified. Then, they propose expectation-maximization (EM) methods to solve the related estimation problem for different subclasses of CTC models, building from the provably convergent outer-approximation algorithm. Finally, subclasses of CTC models are tested on a synthetic data set and on two real data sets: one from a grocery chain and one from a peer-to-peer (P2P) car sharing platform. The results are consistent in assessing that CTC models tend to dominate RUM models with respect to prediction accuracy when the training data are noisy (i.e., transaction records do not necessarily reflect the physical inventory records) and when there is significant asymmetry between the training data set and the testing data set. These conditions are naturally verified in P2P sharing platforms and in retailers working on long-term forecasts (e.g., semester long) or geographical aggregate forecasts (e.g., forecasts at the distribution center level).

Docência, família e currículo: o vazio dos sentidos docentes na política curricular familista
Authors: Da Penha Silva Melanie Laura Mariano
Published: September 2023

O artigo discute o esvaziamento de sentidos docentes a partir do fortalecimento de políticas curriculares familistas no Brasil, as quais endereçando-se prioritariamente à família tradicional, como instância de ensino-aprendizagem, invertem a prioridade do interesse público para investir na ordem privada. Com o objetivo de analisar o esvaziamento discursivo da formação docente como um desdobramento da onda reacionário-conservadora da última década, realiza-se uma análise discursiva ancorada na pesquisa qualitativa documental, a partir de materiais do “Programa Conta pra Mim” que integra a Política Nacional de Alfabetização (PNA). Para tanto, este texto adota a perspectiva pós-estrutural da teoria do discurso de Laclau e Mouffe (2015) como arcabouço teórico-analítico, junto a considerações amparadas na filosofia da diferença de Derrida (2016) e no conceito de lógicas fantasmáticas de Glynos e Howarth (2007). Ante a isto, os achados permitem significar o “Conta pra Mim” como uma proposição de currículo embebida no familismo contemporâneo, afeita a sedimentação de sentidos neoconservadores e neoliberais e aliada aos interesses daqueles que intentam fragilizar os espaços-tempos da docência nas disputas por hegemonia educacional.

The synthesis of zeolite X from bituminous fl y ash (BFA) from the BLCP power plant in Rayong province of Thailand was examined. The initial Si/Al molar ratio of BFA was approximately 2, as determined via X-ray fl uorescence. A stock solution for the hydrothermal synthesis of zeolite X was prepared by extracting the Si and Al species from BFA using 3 M NaOH. The Si/Al molar ratio of the stock solution was 18.44. The Si/Al ratio, temperature, ageing time, and concentrations of NaOH and KOH were investigated during the synthesis of zeolite X. QXRD, SEM, and BET were used for the characterization of zeolite X. For the optimal sample conditions, the Si/Al molar ratio of the stock solution was adjusted to 3 using Na2AlO3 dissolved in a KOH solution, followed by ageing at room temperature for 24 h and after ageing, the hydrothermal synthesis was performed at 75 °C for 24 h; the sample prepared under these conditions contained the highest amount of crystalline zeolite X (98.7%), with a surface area of 527.59 m2/g.

Published: September 2023

This paper examines the analysis of meteorological observations concerning wind direction and intensity. These observations are typically found in regular weather reports, which play a crucial role in the safe arrival and departure of aircraft, and provide vital information about current conditions along airport runways. To ensure accuracy, the locations of wind sensors along runways must be specified in routine weather reports. Furthermore, reported wind information data should be linked to the specific sections of the runway for which the data are representative. In cases where wind observations are available from multiple tracks, the relevant track information should also be included
in routine weather reports, alongside the corresponding wind data. For surface wind conditions, the observations included in the METAR reports should accurately represent the entire runway, and it is important to indicate the specific runway or runway sections to which the observations pertain.

Published: September 2023

There is a close association between tumor response and survival in gastric cancer patients after receiving neoadjuvant treatment. An accurate and rapid assessment of therapeutic efficacy would be helpful for subsequent treatments and individual prognosis. At present, pathological examination is the gold standard for evaluating treatment response, however, it requires additional staining and the process is tedious, labor-intensive, as well as time-consuming. Here, we introduce a label-free imaging technique, two-photon imaging, to evaluate histopathological changes induced by pre-operative therapy, with a focus on assessing tumor regression as well as stromal response. Imaging data show that two-photon imaging allows label-free, rapid visualization of various aspects of pathological alterations in tumor microenvironment such as fibrotic reaction, inflammatory cell infiltration, mucinous response, isolated residual tumor cells. Moreover, a semi-automatic image processing approach is developed to extract the collagen morphological features, and statistical results show that there are significant differences in collagen area, length, width, cross-link space between the gastric cancer tissues with and without treatment. With the advent of a portable, miniaturized two-photon imaging device, we have enough reason to believe that this technique will become as an important auxiliary diagnostic tool in assessing neoadjuvant treatment response and thereby tailoring the most appropriate therapy strategies for the patients.

Published: September 2023

This is a phenomenological study in which seven female firefighters, who experienced emotional labor while performing public services like accident investigation and rescue, were interviewed about their difficulties, psychology and coping, and desires for institutional improvement due to emotional labor and violence during work. This study derived two categories, four theme clusters, and the following ten themes: “An emotional trash can that is required to be unconditionally kind,” “Violence and profanity from citizens flying out of nowhere,” “Female firefighters are seen as weak and unworthy,” “Female firefighters face discrimination even within the organization,” “Doubt and frustration about my job,” “Repeated anxiety and fear,” “My way of shaking off emotional labor” “Emotional labor coping system established within the organization,” “Slowly but surely changing atmosphere within the organization,” and “The beginning of a step toward a better environment.” This study’s findings provide several clinical, policy, and practical implications for creating safe working environments for women firefighters.
Qual o papel do ESG no value relevance? evidências na América Latina no período da pandemia
Authors: Santos Geovane Camilo dos , Tavares Marcelo
Published: September 2023

Objetivo: analisar o value relevance das práticas environmental, social and corporate governance (ESG) no período da pandemia.
Método: a amostra é composta por 1.937 observações de seis países das América Latina. Os dados foram coletados na Refinitiv Eikon® e tratados mediante painel de dados. O modelo de value relevance foi adaptado do estudo de Ohlson (1995).
Resultados: evidenciam que há uma relação positiva e significativa para o lucro por ação e valor patrimonial por ação, conforme o esperado. Todavia, a variável ESG apresentou relação significativa e negativa com o preço das ações para a análise sem separar por período da pandemia, e, quando realizou a segregação constatou que não houve relação significativa. Esses resultados permitem concluir que os investidores das empresas desses países ainda não estão considerando as práticas ESG como um fator preponderante para suas tomadas de decisões.
Contribuição: pode contribuir com investidores, visto que os Princípios de Investimento Responsável das Nações Unidas (PIRNU) recomenda que os eles considerarem as práticas ESG como um fator importante em suas decisões de investimentos. A pesquisa também pode contribuir com os gestores, visto que esses podem observar se o investimento em práticas ESG trazem benefícios para a empresa, uma vez que essas representam redução da assimetria da informação induzindo ao aumento da visibilidade dos negócios das organizações em longo prazo.
Erianin alleviates collagen-induced arthritis in mice by inhibiting Th17 cell differentiation
Authors: Tsai Sen-Wei , Wang Jou-Hsuan , Chang Yu-Kang , Lin Chi-Chen
Published: September 2023

Rheumatoid arthritis (RA) is a chronic autoimmune disorder. Its pathogenesis is complicated but highly related to aberrant Th17 overactivation. Uncontrolled Th17 cell expansion and activation in populations and associated activities contribute to the progression of RA. Although clinical RA remedies are available, not all RA patients respond to these treatments, and adverse effects are always a concerning issue during treatment. To expand the repertoire of possible anti-RA remedies, we chose the phytochemical compound erianin, isolated from Dendrobium sp., and evaluated its antiarthritic effect in vitro and in vivo. We found that erianin efficiently controlled the differentiation and activation of Th17 cell development from primary CD4 T cells, limiting IL-17A cytokine production and RORγT transcript generation. In line with molecular docking models, the essential signaling pathway for Th17 polarization, the JAK/STAT3 pathway, was inhibited upon erianin treatment, with dose-dependent inhibition of phosphorylation shown by western blotting. More importantly, erianin treatment reduced arthritic manifestations and proinflammatory cytokine levels in collagen-induced arthritis (CIA) mice, as well as protecting the joint histological microstructure. Overall, erianin revealed a promising inhibitory effect on Th17 overactivation and decreased disability in CIA mice. Therefore, erianin could be further developed as a candidate RA remedy.
Noise reduction and QRS detection in ECG signal using EEMD with modified sigmoid thresholding
Authors: Mohguen Ouahiba
Published: September 2023

Objectives

Novel noise reduction and QRS detection algorithms in Electrocardiogram (ECG) signal based on Empirical Mode Decomposition (EMD), Ensemble Empirical Mode Decomposition (EEMD) and the Modified Sigmoid Thresholding Function (MSTF) are proposed in this paper.

Methods

EMD and EEMD algorithms are used to decompose the noisy ECG signal into series of Intrinsic Mode Functions (IMFs). Then, these IMFs are thresholded by the MSTF for reduction of noises and preservation of QRS complexes. After that, the thresholded IMFs are used to obtain the clean ECG signal. The characteristic points P, Q, R, S and T peaks are detected using peak detection algorithm.

Results

The proposed methods are validated through experiments on the MIT-BIH arrhythmia database and Additive White Gaussian Noise (AWGN) is added to the clean ECG signal at different input SNR (SNR
in). Standard performance parameters output SNR (SNR
out), mean square error (MSE), root mean square error (RMSE), SNR improvement (SNR
imp) and percentage root mean square difference (PRD) are employed for evaluation of the efficacy of the proposed methods. The results showed that the proposed methods provide significant quantitative and qualitative improvements in denoising performance, compared with existing state-of-the-art methods such as wavelet denoising, conventional EMD (EMD-Conv), conventional EEMD (EEMD-Conv, Stockwell Transform (ST) and Complete EEMD with Adaptative Noise with hybrid interval thresholding and higher order statistic to select relevant modes (CEEMDAN-HIT).

Conclusions

A detail quantitative analysis demonstrate that for abnormal ECG records 207 m and 214 m at input SNR of −2 dB the SNR
imp value is 12.22 and 11.58 dB respectively, which indicates that the proposed algorithm can be used as an effective tool for denoising of ECG signals.
Serious Jokes: Friedrich Schlegel and the Philosophical Use of Irony
Authors: Clow James
Published: September 2023

Though irony is a category familiar to rhetoric and literature, its philosophical forms are far less explored, and this is especially true with regards to its articulation in the work of Friedrich Schlegel. Schlegel’s engagement with irony is essential to the Romantic philosophical project, one that is fundamentally concerned with contradiction and posits itself as a challenge to and continuation of idealism. Through exploring his relation to the philosophies of Kant and Fichte, this essay demonstrates that Schlegel can deploy irony as a method of taking up the philosophical paradigm of idealism without limiting himself to their systems. He can use Kant and Fichte against themselves, making sincere philosophical arguments through a brazen playfulness. Further, Schlegel’s concept of irony is shown to be a philosophical faculty that is concerned with the limits of philosophy in language. Irony is much more than a rhetorical device – it is a form that allows Schlegel to approach the limits of discursivity from within and so continually stage instances of philosophical contradiction, undermining systematicity. This centering of contradiction is one of Schlegel’s major contributions to the development of German philosophy, critical of those who precede him and spurning their presuppositions of univocal logic. The outworking of Schlegel’s philosophical concern with irony is unmistakably humorous, full of puns, jokes and witticisms, which nevertheless need to be taken seriously. This paper contends that irony is at the crux of Schlegel’s philosophical project, simultaneously the content and mode of his criticism, the source and justification of his humour, and one of Romanticism’s most significant conceptual developments.
A CA and ML approach for M-MIMO optical non-orthogonal multiple access power efficiency
Authors: Kumar Arun , Gour Nidhi , Sharma Himanshu
Published: September 2023

The non-orthogonal multiple access (NOMA) multiple access approach can be used in future wireless communication systems to support massive connections and increase spectrum efficiency. Because user signal intensities and interference levels vary, precise channel assessment is essential in NOMA. Optimal power allocation and decoding order are made possible by precise algorithms, increasing system effectiveness and performance. However, NOMA can be adversely impacted by high peak-to-average power ratio (PAPR) values, leading to worsened system performance and more complex power amplifiers. In order to solve this issue, this paper recommends PAPR reduction in NOMA using companding methods for 512, 256, and 64 sub-carriers. Nonlinear companding techniques, such as MA and A-law companding, can efficiently reduce the high peak power of NOMA signals while reducing distortion and enhancing overall system dependability. The effectiveness of the proposed companding methods is evaluated using simulations, and the results demonstrate a significant decrease in PAPR, ensuring higher bit error rate (BER) effectiveness and transmission resilience in NOMA-based communication systems. The proposed approach is compared to the traditional Ml (C- Ml) and A-Law (C- A-Law).

Rapport-building attempts in technology-mediated job interviews during the COVID-19 crisis
Authors: De Dijn Melina , Van De Mieroop Dorien
Published: September 2023

The COVID-19 situation has turned job interview practices upside down: while it was common to organize face-to-face job interviews, there is now a surge in technology-mediated job interviews (TMJIs). This shift to a digital medium self-evidently affects these interactions and earlier research has indeed drawn attention to the – often negative – impact of technology on interactions. For job interviews in particular, the tendency for shorter “rapport-building stages” in TMJIs is regarded as an important disadvantage. In this article, we analyze TMJIs recorded after the start of the COVID-19 crisis from a multimodal discourse analytical perspective. We specifically focus on initial sequences that are hindered by technical issues, as the limiting impact of technology is most tangible in these segments. We found that the digital medium does not necessarily prevent rapport-building efforts. Furthermore, the COVID-19 situation turned out to offer interviewers an almost self-evident point of departure for rapport-building attempts which can be viewed in the light of more encompassing facilitative actions of the recruiters. Hence, this article demonstrates that interlocutors can agentively transform technology-related deficiencies into occasions affording opportunities for potential rapport-building, especially by drawing on the shared nature of the pandemic.

Structural characteristics and visible-light-driven photocatalytic of ZnO@octahedral NiFe2O4 microcrystal prepared via thermal decomposition process
Authors: Keereeta Yanee , Prasatkhetragarn Anurak , Sirirak Reungruthai , Klinbumrung Arrak
Published: September 2023

Owing to the confinement of ZnO in the photocatalytic application: the wide bandgap, the rapid photogenerated carriers recombination, and the expensive cost for the catalyst separation from the wastewater, the p-n heterojunction of NiFe2O4 magnetic phase and ZnO is considered to improve the photocatalytic efficiency and the catalyst separation by the external magnetic. The NiFe2O4/ZnO composites with 0–12 wt% of NiFe2O4 were prepared by an ordinary process and characterized using XRD, Raman, SEM, EDS, TEM, HRTEM, UV–Vis spectroscopy, and PL techniques. The Raman spectra confirm the crystallinity of ZnO and NiFe2O4, including their defects. As increasing NiFe2O4 incorporation, the crystallite size of ZnO phase depicts a lower value with changing from 53.14 to 40.49 nm, whereas NiFe2O4 phase reveals a greater value of 60.61–141.55 nm. The dislocation density, lattice constants, and atomic coordinates are also discussed in terms of ion diffusion. The morphology analysis reveals ZnO particles on the surface of NiFe2O4 microcrystals, confirming the p-n heterojunction formation. The energy bandgap of the as-synthesized samples is in the range of 1.52–2.85 eV, suggesting to the visible light photocatalysis. The prominent PL spectrum indices the forming of Zn interstitial defect state. Under the visible light irradiation, the dye degradation was investigated as a result of the photoreduction percentage and catalyst dosage. With prepared by a facile process, 12 wt% NiFe2O4-loaded ZnO displayed the high methylene blue degradation of 96.96 % within 150 min under visible light irradiation, confirming an excellent photocatalyst. Due to the microstructural composite, the active surface site and the p-n heterojunction were elucidated as the principal mechanism for the difference in reaction time. The dye degradation was discussed in association with the structural constants, morphology, and defects.
Activity level and quality of life among patients before and after total knee replacement surgery
Authors:   ,   PTE ETK Egészségtudományi Doktori Iskola, Alfatafta Huda Hamdan Naim
Published: September 2023

Knee osteoarthritis (OA) is a serious musculoskeletal injury and the leading cause of disability, low activity level, and low quality of life in Hungary and worldwide. Various treatments are currently available to address knee OA that could be knee valgus brace and total knee replacement (TKR). The two different interventions aim to reduce pain and increase the activity level to enhance the quality of life; however, some questions are still poorly addressed, or insufficient information is available about these two types of interventions. So, this thesis covered four aspects and found that using the knee valgus brace could reduce pain and enhance the quality of life, but using the knee valgus brace could be more recommended and suitable for patients with mild and moderate knee OA than others. In addition, total knee replacement surgery is an effective surgery, and the number of steps significantly increased after surgery; however, the sedentary time was still high and could reduce the efficiency of the surgery. Therefore, to increase the efficiency of TKR surgery, it is important to reduce sedentary time. Furthermore, the activity level and pain among the recruited Hungarian patients were enhanced one year after surgery; however, the sedentary time after surgery should be reduced more to reach the maximum benefits of surgery. Moreover, the recruited Hungarian patients with severe knee OA had low activity levels and high pain level, and the recruited Hungarian women with severe knee OA had lower functional levels due to emotional problems than the included Hungarian men. Hence, it is necessary to include intensive emotional treatment in the rehabilitation strategy for patients with severe knee OA in Hungary to enhance their quality of life. Finally, further studies are recommended with more participants and longer follow-ups.

Sua concepção de sentido da vida tenta captar o que há de essencial nas duas grandes visõescompartilhadas pelo senso comum sobre o assunto, segundo as quais: a) a morte é um obstáculo paraque a vida tenha sentido, e b) cumprir o propósito de Deus é necessário para o sentido. Nozickconfrontará ambas as noções, mostrando-as insustentáveis, mas ainda assim trazendo, no seu íntimo,aspectos importantes a serem levados em conta na constituição da noção de sentido da vida. A partirdisso, Nozick defenderá que o sentido tem a ver com estabelecer conexões que transcendem os limitesdo eu, levando-nos a uma discussão metafísica sobre o ilimitado. Ao mesmo tempo em que flerta comuma posição poder-se-ia dizer religiosa, verificaremos que o filósofo tenta escapar dos seus impasses,encontrando uma alternativa para viabilizar o sentido mesmo em um universo que não conta com aexistência do ilimitado. Nozick acreditará encontrar tal alternativa na noção de valor. Defenderemos queessa reviravolta naturalista é um tanto problemática e guarda, na tentativa de garantir a possibilidade desentido sem depender do transcendente, fragilidades internas

No caso, o projeto do Observatório Global de Patologias Sociais, vinculado ao Print/UFPel, tem-se mostrado em exemplo de solidariedade conjunta entre pesquisadores de áreas distintas, como a educação, filosofia, odontologia e outros campos da pesquisa e do conhecimento.
A DOR DO PONTO DE VISTA CLÍNICO
Authors: Boscato Noéli , Garcia Torino Gabriela
Published: September 2023

A dor do ponto de vista clínico é definida como estímulo e resposta a partir de fenômeno biológicos complexos e subjetivos nas dimensões sensorial-discriminativa, afetivo-motivacional e cognitivo-avaliativo. Sua definição tem sido um desafio ao longo da história, desde a sua percepção como uma experiência espiritual e mística nos primórdios tempos, até o seu entendimento em termos biológicos como uma sensação física e mecânica que passa pelas fibras e alcança o cérebro. A dor é um efeito extremamente necessário uma vez que é um sinal de alarme de que algum dano ou lesão está ocorrendo, embora a dor possa também estar presente na ausência de qualquer estímulo, dano ou doença detectável. Preponderantemente a dor é eliminada uma vez que o estímulo nocivo é removido, no entanto, a dor pode persistir apesar da remoção do estímulo e cicatrização aparente do tecido sendo denominada de dor crônica, com influência multidimensional. O limiar de dor fisiológico é definido como o ponto ou momento em que um dado estímulo é reconhecido como doloroso, o que pode variar de um indivíduo para o outro, e ainda estar associado as experiências prévias com lesão tecidual real ou potencial e a fatores psicológicos. Dessa forma, esta análise aborda a etimologia, histórico e evolução na concepção da definição da dor do ponto de vista clínico baseada na antiga e recente definição de dor pela Associação Internacional para Estudos da Dor frente ao contexto biológico que inevitavelmente é influenciado pelas condições psicossociais. Pode-se finalmente, estabelecer que há fortes indícios de associação entre lesão tissular e dor biológica com o sofrimento, comportamentos dolorosos e incapacidade. É evidente que o sofrimento e o comportamento originados a partir da dor do ponto de vista clínico, não se devem inteiramente à nocicepção originada por uma lesão tissular, pois os comportamentos dolorosos podem perpetuar-se em decorrência de fatores ambientais e de influências que não podem ser objetivamente avaliadas. A partir desse contexto, os bons programas de controle de dor devem ter uma abordagem cognitivo-comportamental e incorporar estratégias terapêuticas físicas, farmacológicas e psicológicas. Nenhum tratamento isolado é tão eficaz para a redução da dor crônica refratária como a conduta multidisciplinar.

Este artigo apresenta uma revisão de literatura, que possui como objetivo investigar como o fenômeno corpolatria está inserido em publicações científicas. Teve como lócus três portais de buscas (Scielo, Portal de Periódicos da CAPES e Google Acadêmico) e recorte temporal de 2012 a 2021. Os dados foram analisados qualitativamente, no qual, averiguou-se a conceituação de corpolatria destacada na literatura e o local de origem dos estudos. A partir dos resultados, inferiu-se que a temática ainda é incipiente entre os pesquisadores brasileiros, embora haja boa distribuição geográfica dos estudos. Percebeu-se que corpolatria é uma patologia da modernidade, caracterizada pelo culto exagerado do corpo, referendada como uma espécie de ditadura corporal, estabelecida pelo discurso do corpo perfeito. Disseminada pela mídia, pelas redes sociais e pela sociedade, caracteriza-se como uma patologia social à medida que causa mal-estar social, pois pode gerar consequências físicas, transtornos psicológicos e insegurança.

Este texto aborda as bases teóricas e metodológicas desenvolvidas no Observatório Global de Patologias Sociais. Tal observatório visa diagnosticar patologias sociais nas áreas da saúde e da educação, além de, como prognóstico, fornecer subsídios para a organização de um instrumento capaz de captar a percepção de patologias sociais em distintas populações. A partir das discussões técnicas e filosóficas, com base nas leituras de autores da Teoria Crítica, principalmente Honneth (2006; 2011; 2016), têm-se desenvolvido, desde 2019, a organização de um conjunto de perguntas que são a base do instrumento denominado de questionário de patologias sociais. De forma concomitante, o trabalho de construção do Glossário de Patologias Sociais ampliou as reflexões teóricas dentro do grupo, possibilitando ainda a consolidação nacional e internacional de redes de investigação e colaboração dentro do espaço do Observatório. Todos esses movimentos permitem o aprimoramento de nossa caminhada como grupo transdisciplinar, tanto na construção do instrumento como no aprofundamento de bases teóricas-conceituais. Assim, torna-se a cada instante mais clara a necessidade de cumprir com um dos objetivos primários do Observatório: compreender e monitorar como as patologias sociais são percebidas pelos cidadãos e como esses são afetados física e emocionalmente por essas patologias. Deste modo, os desafios têm sido, além de consolidar nosso arcabouço teórico, o de construir um instrumento próprio e capaz de mensurar a percepção a partir do olhar do cidadão comum. Um desafio adicional a elaboração do instrumento, tem sido nossos esforços de construí-lo seguindo os princípios de integridade em pesquisa e usando práticas de ciência aberta. Levando em conta as discussões teórico-práticas, o Observatório tem se destacado como um espaço de pesquisa e estudo relevante e eficaz diante das demandas contemporâneas de compreender a sociedade onde vivemos.
HABERMAS, RAWLS E ARENDT
Authors: José Volpato Dutra Delamar
Published: September 2023

O texto analisa quais teriam sido as razões estruturais pelas quais Habermas, no seu texto sobre a desobediência civil de 1983, estranhamente, não referencia o nome de Arendt, mas o de Rawls. Para isso, apresenta alguns elemen tos do t ratamento arendtiano da desobediên cia civil que inviabilizaram o alinhamento do trabalho de Habermas sobre a desobediência civil [1983] com aquele da pensadora. Por fim, aponta para as prox imidades da teoria de Habermas com aq uela de Rawls, muito embora com ciência das diferenças importantes entre as duas propostas.
A HESITAÇÃO DE JÜRGEN HABERMAS
Authors: F. L. Gomes David
Published: September 2023

este artigo objetiva apresentar um panorama sobre o modo como Habermas aborda a relação entre capitalismo, democracia e crise no marco de suas análises sobre o Estado de Bem-Estar Social. Para tanto, divide-se sua obra em 4 momentos: o primeiro de 1962 a 1971; o segundo de 1973 a 1981; o terceiro de 1985 a 1992; e o último de 1992 até os dias de hoje. Sua principal justificativa é a relevância contemporânea dessa discussão, em face das recentes ameaças autoritárias na América Latina e no mundo. A hipótese fundamental é que com esses três elementos conceituais – capitalismo, democracia, crise, Jürgen Habermas coloca a si mesmo em uma encruzilhada paralisante, pois ele enxerga as tensões inevitáveis entre tais elementos, mas hesita diante das opções para sair do amálgama que eles hoje formam. Dois são os motivos principais para essa hesitação: um reducionismo empiricista e um paradoxal déficit de complexidade em sua teoria social.
Sports and Alzheimer’s Disease: The Role of Physical Activity in Cognition Health
Authors: Kaur Nhu , Ng Terry Lee
Published: September 2023

Alzheimer’s disease (AD) is an advancing neurodegenerative condition distinguished by a gradual deterioration of cognitive functions, including memory impairment and diminished functional capabilities. The issue presents a substantial global public health concern, as there is a growing prevalence of affected persons annually. In the pursuit of innovative strategies to delay or mitigate the beginning of AD, scholars have turned their attention to the exploration of physical activity as a potentially fruitful area of study. This review aims to investigate the correlation between engagement in sports activities and the development of AD. It will analyze the potential advantages of physical exercise on cognitive well-being and discuss the significance of these findings for strategies related to the prevention and treatment of the disease. We integrate data derived from epidemiological investigations, clinical trials, and neuroscientific inquiries, thereby emphasizing the existing body of knowledge in this pivotal domain.
How Crystalline is My Cellulose Specimen? Probing the Limits of X-ray Diffraction
Authors: French Alfred D.
Published: September 2023

Cellulose serves as a skeleton for many of the useful products upon which we rely on each day. When we want to learn about a skeleton, it makes sense to think about X-ray methods. The same can be said when it comes to learning about the crystallinity of cellulose. Over the past six decades, the Segal X-ray diffraction (XRD) method has been popular for judging the percent crystallinity of powder samples. However, XRD patterns for ideal cellulose crystals can be easily simulated, and limitations of the Segal and other methods become obvious. Calculated patterns for model 100% crystalline powder particles are predicted to be less crystalline by the Segal method. Except for the Rietveld method, current approaches do not account for particle orientation or different shapes of crystallites. The Rietveld method has so many variables that it can easily overfit the data. The take-away message is that routine XRD examination is important for showing sample characteristics, but fractional crystallinity values are affected by constraints related to simplifications required for the analysis.

This study investigated the possibility of furniture factory waste sawdust (FFWS) utilization in polypropylene (PP) composites and producing furniture support leg prototypes. Test samples were manufactured using a single screw extruder and injection molding machine utilizing 10, 15, 20, 25, 30, and 35% by weight of FFWS and 0% or 3% maleated polypropylene (MAPP). Selected mechanical and physical properties of manufactured samples were determined. The presence of FFWS and MAPP significantly improved mechanical properties compared to neat PP. The higher FFWS amount increased the flexural strength, flexural modulus, tensile modulus, impact resistance, and density. Tensile strength and elongation at break decreased with filler amount, but the addition of MAPP caused a dramatic increase in tensile strength. In addition, flexural strength, flexural modulus, tensile strength, elasticity modulus, and density values of the composites containing MAPP had higher values than the ones without MAPP. However, impact resistance and elongation at break values were slightly decreased with the addition of MAPP. Optimization results showed that formulation mixtures containing 20% filler and 3% MAPP fit best for prototype furniture legs manufacturing.
