Authors: Yang Yuting , Mirzaei Golrokh
Published: February 2024

Cancer, in any of its forms, remains a significant public health concern worldwide. Advances in early detection and treatment could lead to a decline in the overall death rate from cancer in recent decades. Therefore, tumor prediction and classification play an important role in fighting cancer. This study built computational models for a joint analysis of RNA seq, copy number variation (CNV), and DNA methylation to classify normal and tumor samples across liver cancer, breast cancer, and colon adenocarcinoma from The Cancer Genome Atlas (TCGA) dataset. Total of 18 machine learning methods were evaluated based on the AUC, precision, recall, and F-measure. Besides, five techniques were compared to ameliorate problems of class imbalance in the cancer datasets. Synthetic Minority Oversampling Technique (SMOTE) demonstrated the best performance. The results indicate that the model applying Stochastic Gradient Descent (SGD) for learning binary class SVM with hinge loss has the highest classification results on liver cancer and breast cancer datasets, with accuracy over 99% and AUC greater than or equal to 0.999. For colon adenocarcinoma dataset, both SGD and Sequential Minimal Optimization (SMO) that implements John Platt’s sequential minimal optimization algorithm for training a support vector machine shows an outstanding classification performance with accuracy of 100%, AUC, precision, recall, and F-measure all at 1.000.

Published: February 2024

Background

Acute Flaccid Paralysis (AFP) surveillance is the gold standard in the polio eradication initiative. The environmental component of polio surveillance can detect circulating Polioviruses from sewage without relying on clinical presentation. The effectiveness of the Environmental Surveillance (ES) is crucial to global polio eradication. We assessed the usefulness and attributes of the ES system in the Northern region and determined if the system is meeting its objectives.

Methods

We conducted a descriptive cross-sectional evaluation in the Northern region from 2019 to 2020 using the updated US Centers for Disease Control and Prevention guideline. We interviewed stakeholders, reviewed records, and observed surveillance activities from 29th March to 7th May, 2021. Quantitative data were analyzed manually as frequencies and proportions whiles thematic analysis was used for the qualitative data.

Results

One of 48 (2.1%) samples collected tested positive for circulating vaccine-derived Poliovirus (cVDPV). The cVDPV detection triggered enhanced AFP surveillance that resulted in the identification of a case of AFP. Three rounds of polio vaccination campaigns were organized. All surveillance officers interviewed were willing to continue providing their services for the ES. Reporting form has few variables and is easy to complete. The completeness of forms was 97.9% (47/48). Samples collected were dispatched on the same day to the testing laboratory. The system’s data was managed manually.

Conclusion

The system was useful in detecting polio outbreaks. Data quality was good, the system was simple, flexible, acceptable, representative, and fairly stable. Sensitivity was high but predictive value positive was low. Timeliness in reporting was good but feedback from the national level could not be assessed. There is a need to improve on the feedback system and ensure that, the surveillance data is managed electronically.

Authors: Ji Zhongkui , Gao Lijun , Guo Shuquan , Sun Kui , Ma Wanchao , Wu Boqiang , Xue Xiaoyuan , Chen Pan
Published: February 2024

In this study, the slurry diffusion in a cavity filled with coal gangue was studied by combining experimental and numerical simulation methods. By calibrating slurry and particle materials, the grouting process in coal gangue filling area is simulated successfully, and the change of slurry diffusion flow field and particle movement and settling process in different dimensions are deeply analyzed. Both experimental and numerical simulation results show that the particle settlement presents a bell-shaped curve, which is of great significance for understanding the particle movement and settlement behavior in the filling cavity. In addition, it is found that the grouting speed has a significant effect on the particle settlement during the slurry diffusion process. When the grouting speed increases from 0.1m /s to 0.2m /s, the particle settlement and diffusion range increases about twice. In the plane flow field, it is observed that the outward diffusion trend and speed of grouting are more obvious. It is worth noting that in the whole process of grouting, it is observed that with the increase of grouting distance and depth, both the velocity of slurry and particles show a trend of rapid initial decline and gradually slow down, and the flow velocity of slurry near the grouting outlet at a flow rate of 0.2m/s is 2–4 times that of 0.1m/s. This provides important enlightenment for the porous seepage effect at different grouting speeds.

Published: February 2024

Objectives

A positive work environment (WE) is paramount for healthcare employees to provide good quality care. To stimulate a positive work environment, employees’ perceptions of the work environment need to be assessed. This study aimed to assess the reliability and validity of the Dutch version of the Culture of Care Barometer (CoCB-NL) survey in hospitals.

Methods

This longitudinal validation study explored content validity, structural validity, internal consistency, hypothesis testing for construct validity, and responsiveness. The study was conducted at seven departments in two Dutch university hospitals. The departments were included based on their managers’ motivation to better understand their employees’ perception of their WE. All employees of participating departments were invited to complete the survey (n = 1,730).

Results

The response rate was 63.2%. The content of the CoCB-NL was considered relevant and accessible by the respondents. Two factor models were found. First, confirmative factor analysis of the original four-factor structure showed an acceptable fit (X2 2006.49; df 399; p = <0.001; comparative fit index [CFI] 0.82; Tucker-Lewis index [TLI] 0.80; root mean square error of approximation [RMSEA] 0.09). Second, explanatory factor analysis revealed a five-factor model including ‘organizational support’, ‘leadership’, ‘collegiality and teamwork’, ‘relationship with manager’, and ‘employee influence and development’. This model was confirmed and showed a better fit (X2 1552.93; df 395; p = < 0.00; CFI 0.87; TLI 0.86; RMSEA 0.07). Twelve out of eighteen hypotheses were confirmed. Responsiveness was assumed between the measurements.

Conclusions

The CoCB-NL is a valid and reliable instrument for identifying areas needing improvement in the WE. Furthermore, the CoCB-NL appears to be responsive and therefore useful for longitudinal evaluations of healthcare employees’ work environments.

Published: February 2024

Background

Obesity is a global health issue with increasing prevalence. Surgical procedures, such as surgical stabilization of rib fractures (SSRF), may be affected by obesity-related complications. The objective of the study is to investigate the effects of obesity on SSRF outcomes in multiple rib fractures.

Methods

This retrospective study analyzed data from adults aged ≥ 20 years in the Nationwide Inpatient Sample (NIS) database diagnosed with multiple rib fractures who underwent SSRF between 2005 and 2018. It investigated the relationship between obesity and in-patient outcomes, such as discharge status, length of stay (LOS), in-hospital mortality, hospital costs, and adverse events using logistic and linear regression analyses.

Results

Analysis of data from 1,754 patients (morbidly obese: 87; obese: 106; normal weight: 1,561) revealed that morbid obesity was associated with longer LOS (aBeta = 0.07, 95% CI: 0.06, 0.07), higher hospital costs (aBeta = 47.35, 95% CI: 38.55, 56.14), increased risks of adverse events (aOR = 1.63, 95% CI: 1.02, 2.61), hemorrhage/need for transfusion (aOR = 1.77, 95% CI: 1.12, 2.79) and mechanical ventilation ≥ 96 hours (aOR = 2.14, 95% CI: 1.28, 3.58) compared to normal weight patients. Among patients with flail chest, morbid obesity was significantly associated with tracheostomy (aOR = 2.13, 95% CI: 1.05, 4.32), ARDS/respiratory failure (aOR = 2.01, 95% CI: 1.09, 3.70), and mechanical ventilation ≥ 96 hours (aOR = 2.80, 95% CI: 1.47, 5.32). In contrast, morbid obesity had no significant associations with these adverse respiratory outcomes among patients without a flail chest (p > 0.05).

Conclusions

Morbid obesity is associated with adverse outcomes following SSRF for multiple rib fractures, especially for flail chest patients.

This special issue explores the multifaceted dimensions of men’s fashion, examining its intricacies through the lens of atmospheres. Atmospheres serve a dual role, functioning as a contextual frame that shapes men’s fashion and analytical frameworks that unify diverse influences on masculine dress. Articles within the issue explore the atmospheres of men’s fashion across various settings, including en plein air painting, online avatars, music videos, performative personas in popular music, raves and military uniforms. Employing historical, visual, textual, ethnographic and practice-led approaches, these investigations shed light on the interplay of spatial, bodily and affective dimensions of fashion. Atmospheres become a bridge, addressing the gap between these dimensions and providing a generative notion to understand interdependent interactions within masculine fashion contexts. Consequently, the issue underscores the significance of men’s fashion as a carrier of social life within broader socio-cultural, technological and political assemblages. By scrutinizing specific instantiations of men’s fashion, the special issue forges connections between typically distinct elements in the field, emphasizing the interdependence of individuals, equipment, technologies, practices and environments.
Modding masculinities: Video game glitches and transcending gendered dress
Authors: Drak Daniel , Barry Ben
Published: February 2024

Gaming avatars are often confined to a predetermined set of bodies, identities and clothing options that reinforce gender norms. In response, players have participated in modifying the existing bodies and clothing choices available for their avatars to represent their experiences. This article draws on concepts of the glitch and antigender fashion to engage in a textual analysis of The Sims 4. We explore how modifications for avatars’ appearance and clothing create spaces for players to transcend dominant notions of masculinity and produce a variety of gendered-dressed embodiments. Our analysis understands video games as atmospheres and modifications as glitches that expand the gendered possibilities within virtual worlds. However, the expansion of masculinities in The Sims 4 relies on the labour of players from marginalized communities and, as such, reaffirms gender power structures. Our article introduces video games as sites where players construct, negotiate and subvert dressed masculine embodiments.
Spectral cinema: Invisible things are not necessarily not there
Authors: Mortimer Roz
Published: February 2024

This editorial introduces the Special Issue of Moving Image Review & Art Journal (MIRAJ), ‘Spectral Cinema and Contested Landscapes’, a volume that has been created in response to the symposium of the same name that was held at University for the Creative Arts in 2022. In the journal, as in the symposium, we frame a discussion around how the spectral can be interpreted and re-evaluated through contemporary socially and politically motivated moving image practice. Articles by Struan Gray, Astrid Korporaal, Cecília Mello, Louise K. Wilson and Kate Woodward are accompanied by a conversation between artist-filmmaker Juanita Onzaga and philosopher Michaela Kinghorn. The editorial highlights how these discussions circle around animism, fear, unresolved trauma, totalitarianism, the agency and intention of affect, phantasmagorical cinema, and how the more-than-human can lead us to re-interpret positivist approaches to knowledge construction. The ghosts the authors bring to the page are variously disruptive, unruly, fantastical, playful and politically motivated. The spectres in these essays have no temporal boundaries, they can move backwards and forwards through time, not just pulling us back to the past, but more effectively bringing the past forwards to meet us in the present. As ghosts they are often bound to specific locations that are politically significant, and they manifest to remind us not to look away, that something unresolved needs to be attended to. The authors in this volume demonstrate these ideas through their discussions and analyses of the spectral within cinema, sonic arts and artists’ moving image.
Phantasmagorical realism in Memoria (Apichatpong Weerasethakul 2021)
Authors: Mello Cecília
Published: February 2024

This article proposes a close analysis of the film Memoria by Apichatpong Weerasethakul (2021). It begins by situating the film within a broader trend in contemporary East/South East Asian and Latin American cinemas, which incorporates elements of the phantasmagorical into an aesthetics of realism. The combination of these seemingly contradictory concepts gives rise to a sophisticated interplay of temporalities. This interplay comprises the present phenomenological reality, layers of the past and the realm of memory associated with posthumous presences, and the unusual occurrences that may belong to the future. I refer to this phenomenon as ‘phantasmagorical realism’, a recurring theme in Weerasethakul’s cinema. This concept is partly influenced by non-European philosophies and belief systems, such as Thai Buddhism and Animism. In Memoria, this is further accentuated by intermedial connections with Latin American magical realism and Chinese classical literature, both of which are also influenced by non-European philosophies and belief systems, including Amerindian Perspectivism and Daoism.

Published: February 2024

Background and Aim: The threat of emerging and epidemic-prone diseases is a significant public health concern and there is an urgent need to work on the prevention and control of these diseases. In view of the limited time and other resources available to the animal and human health sector, it is crucial to prioritize the most essential and critical risk factors and diseases. This scoping review aims to document the available disease and risk prioritization tools by evaluating their characteristics and suitability from the One Health perspective.

Materials and Methods: Databases such as PubMed, Scopus, and Google Scholar were used to extract available tools for prioritization. We compared and synthesized the objective of the tool, methodology and prioritization process of the available tools.

Results: A total of six tools, including One Health Zoonotic Disease Prioritization, European Centre for Disease Prevention and Control, Strategic Toolkit for Assessing Risks, One Health Systems Mapping and Analysis Resource Toolkit, Health Hazard Assessment and Prioritization tool, Risk Ranger, are included in this scoping review. Various prioritization methods are available; however, multi-criteria decision analysis is the most commonly used.

Conclusion: A thorough analysis showed that different tools employ different prioritizing approaches, including mixed-method, quantitative, and qualitative approaches. The summary of the findings suggests the development of a new robust tool with a One Health approach, which will focus on risk prioritization and disease prioritization.

Keywords: disease prioritization, prioritization in public health, prioritization tool, risk prioritization.

Teoria da Reprodução Social
Authors: Arruzza Cinzia , Bhattacharya Tithi
Published: February 2024

Este texto retoma os elementos fundamentais da Teoria da Reprodução Social, enquanto aposta em um feminismo marxista contemporâneo. Ele começa pela definição do que é a reprodução social no capitalismo e segue para os debates sobre as relações entre produção e reprodução, o papel que a família desempenha, como pensar a sexualidade e os direitos reprodutivos e como os processos de espoliação neoliberal podem ser lidos com base na reprodução social. Esses tópicos são desenvolvidos em diálogo com outras tradições da teoria feminista, como o materialismo francês, a interseccionalidade, a aposta pelos “ Comuns” e o autonomismo.

Published: February 2024

O câncer de colo de útero é a principal neoplasia entre as mulheres, porém, não é a única patologia que acomete a população feminina. O programa “Previne Brasil” foi criado pelo Ministério da Saúde para traçar estratégias e medidas preventivas a populações específicas da Atenção Primária à Saúde. Pelo programa, a realização da coleta de citopatológicos atualmente faz parte do indicador 4 do “Previne Brasil”, que utiliza ações estratégicas na assistência à saúde da mulher. Assim, objetivou-se identificar os impactos do indicador 4 na assistência à saúde da mulher, através de um comparativo entre a percepção dos profissionais de saúde e das usuárias do serviço. Trata-se de um estudo descritivo de natureza quantitativa, utilizando questionários de autoria própria e realizado em todas as Unidades Básicas de Saúde do município de Imaculada-PB, com médicos, enfermeiros e mulheres com idades entre 25-64 anos que realizam coleta de citopatológico na UBS. A partir dos dados coletados, foi possível identificar que a implantação do indicador é de grande importância para melhoria na assistência à saúde da mulher, analisar a percepção das usuárias e profissionais sobre o atendimento prestado e expor fragilidades na realização do exame e no indicador, que não reflete bem o grupo alvo que se propõe, além de sugerir medidas que ampliem a assistência à saúde da mulher.
Kapitel 9 Expert*innenwissen und dialektisches Lernen: Dialoge über Praktiken des Teilens und urban commoning
Authors: Cermeño Helena , Koch Florian , Bretfeld Nada
Published: February 2024

Nach einer kurzen Einführung in die akademische Diskussion über Sharing Economy, urban commoning und das Lernen über und in Stadtplanungssystemen, analysieren Helena Cermeño, Florian Koch, und Nada Bretfeld die drei Dialogveranstaltungen, die im Rahmen des Forschungsprojekts StadtTeilen durchgeführt wurden. Dabei werden bestehende Gemeinsamkeiten und Unterschiede von Sharing-Praktiken in den Städten Berlin, Kassel und Stuttgart unter Berücksichtigung der Variationen in Stadtgröße, Immobiliendynamik, Macht der Zivilgesellschaft und politischem Kontext betrachtet. Der Beitrag reflektiert auf eine Metaebene das dialektische Lernen das durch die Zusammenführung verschiedener Akteur*innen aus urbanen Initiativen, Stadtplanungsentscheidungen und akademischer Forschung in einer Dialogplattform entstehen kann. Hierbei spielen die vielfältigen und manchmal widersprüchlichen Wissensansprüche der Beteiligten eine entscheidende Rolle. Die präsentierten Sharing-Praktiken können unter bestimmten Bedingungen sozial vielfältige Nachbarschaften erhalten, Lernprozesse fördern und somit einen fruchtbaren Beitrag zum Aufbau von mehr Commons-basierter Resilienz in Städten betrachtet werden.

Sharp bounds on the survival function of exchangeable min-stable multivariate exponential sequences
Authors: Mai Jan-Frederik
Published: February 2024

We derive lower and upper bounds for the survival function of an exchangeable sequence of random variables, for which the scaled minimum of each finite subgroup has a univariate exponential distribution. These bounds are sharp in the sense that both bounds themselves are attained by exchangeable sequences of the same kind, for which the (non-scaled) minimum of each subgroup has the same univariate exponential distribution as the original sequence. This result is equivalent to inequalities between infinite-dimensional stable tail dependence functions, which leads to inequalities between multivariate extreme-value copulas. In addition, it is explained how an infinite-dimensional symmetric stable tail dependence function can be obtained from its upper bound by censoring certain distributional information. This technique is applied to derive new parametric families.
Synthesis of humic acid with the obtaining of potassium humate based on coal waste from the Lenger deposit, Kazakhstan
Authors: Smailov Bakyt , Aravind Usha
Published: February 2024

This article a synthesis of humic acid with the obtaining of potassium humate based on coal waste from the Lenger deposit. Accumulated industrial waste heavily pollutes the environment and has a direct impact on all living things. The accumulation of waste in landfills increases the pollution level of the atmosphere, soil, groundwater, and surface water, destroys the functioning of ecosystems, and damages agriculture and construction. A sieve analysis was carried out to study the fine fractions of coal waste, and a scanning electron microscope analysis was performed to study the mineralogical, structural state and X-ray chemical phase composition. The chemical composition of coal waste was studied using differential thermal analysis during heat treatment. The optimal parameters of the process for obtaining humic acids are established, and the results of experimental work are presented. The results are confirmed by mathematical planning of the experiment using the method of orthogonal plan of the second order. The mathematical planning results were tested according to the Student and Fischer criteria. Based on the conducted studies, it was identified that the degree of extraction of humic acid reaches up to 95.90% in terms of the organic phase, and the concentration of humic acid is 49.13%. From the humic acids obtained using potassium hydroxide, potassium humate was synthesized. The potassium humate obtained in its composition has fertilizer properties. Therefore, the obtained potassium humate will be used for the production of humic fertilizers to improve soil fertility and crop yields. The synthesis of humic acids with the production of potassium humate is aimed at reducing the accumulated industrial waste, which in turn allows you to regulate and improve the ecological situation and green ecology in the region.
Automatic boomerang attacks search on Rijndael

Boomerang attacks were introduced in 1999 by Wagner (The boomerang attack. In: Knudsen LR, editor. FSE’99. vol. 1636 of LNCS. Heidelberg: Springer; 1999. p. 156–70) as a powerful tool in differential cryptanalysis of block ciphers, especially dedicated to ciphers with good short differentials. They have been generalized to the related-key case by Biham et al. (Related-key boomerang and rectangle attacks. In: Cramer R, editor. Advances in Cryptology - EUROCRYPT 2005, 24th Annual International Conference on the Theory and Applications of Cryptographic Techniques, Aarhus, Denmark, May 22–26, 2005, Proceedings. vol. 3494 of Lecture Notes in Computer Science. Springer; 2005. p. 507–25. doi: 10.1007/11426639_30). In this article, we show how to adapt the model proposed in 2020 by Delaune et al. (Catching the fastest boomerangs application to SKINNY. IACR Trans Symm Cryptol. 2020;2020(4):104–29) for related-key boomerang attacks on the block cipher SKINNY to the Rijndael case. Rijndael is composed of 25 instances that could be seen as generalizations of the Advanced Encryption Standard. We detail our models and present the results we obtain concerning related-key boomerang attacks on Rijndael. Notably, we present a nine-round attack against Rijndael-128-160, which has 11 rounds and beats all previous cryptanalytic results against Rijdael-128-160.

Miniature Compact Tension Specimens for Upper Shelf Fracture Toughness Measurements on RPV Steels
Authors: Lucon Enrico , Scibetta Marc
Published: February 2024

Miniature compact tension, MC(T), specimens (thickness B = 4.15 mm) have been recently investigated at SCK∙CEN for measuring the fracture toughness of steels under fully ductile conditions (upper shelf regime). The first results of this assessment, made by comparison with results obtained from 1TC(T) samples of various RPV steels with quite different toughness properties, have been described in a previous paper by the same authors. It was observed that, although a systematic and significant underestimation of both critical toughness values and crack propagation resistance was observed for the MC(T) samples with respect to the bigger specimens, it is possible to establish an empirical correlation between the two geometries which allows deriving acceptable estimates of the material's critical toughness. In this work, further investigations are presented, related to: (1) the behavior of MC(T) and 1TC(T) specimens in the crack tip blunting phase; (2) the role of work hardening in decreasing the tearing resistance of MC(T) specimens; and (3) the use of alternative parameters (crack-tip opening displacement, crack-tip opening angle, Ernst's modified J-integral JM). Evidence is also presented which could justify a revision of the specimen measuring capacity (Jmax) in the current ASTM Standard E1820-05, which appears too severe and could be relaxed. Further work will include validating on irradiated materials the empirical correlations established between 1TC(T) and MC(T) test results.
Application of Subsize Specimens for Re-Irradiation Embrittlement Monitoring of the First Generation of VVER-440 RPV Steels
Authors: Shtrombakh Ya. I. , Nikolaev Yu. A. , Nikolaeva A. V.
Published: February 2024

The first generation of VVER-440 Units were not supplied with RPV steel surveillance programs. Therefore, cutting out of samples (tem-pletes) from the inner side of RPV wall is the only possibility for re-irradiation embrittlement monitoring of the first generation of VVER-440 RPV steels. Calculations showed that it is possible to cut out a sample of 7×60×95 mm (with consequent repair) from a RPV core weld. Thus, it is impossible to machine the standard 10×10×55 mm Charpy V-notch specimens to determine RPV steel radiation embrittlement. Therefore it is necessary to use subsize specimens (5×5×27.5 mm and 3×4×27 mm) for ductile-to-brittle transition temperature evaluation of templet material. The small samples were cut out from the inner surface of the all old Russian VVER-440 RPVs to assess the actual condition of the RPV material before and after post-irradiation annealing and after re-irradiation. Special monitoring programs of periodic sampling of RPVs and re-irradiation of the templet material in surveillance channels of VVER-440∕213 RPVs were developed. The state of the art of application of subsize specimens for re-irradiation embrittlement monitoring of the first generation of VVER-440 RPV steels is discussed.

In this paper, a method is applied for the identification of hardening parameters in the brittle-ductile transition region and the determination of Weibull parameters in the brittle region using small-punch tests. A small-punch-test device is developed to measure the load-displacement curve for non-irradiated and irradiated specimens of a reactor vessel steel at different temperatures inside a hot cell. In a global optimization algorithm for the identification of hardening properties, time-consuming finite element method (FEM) calculations are avoided by using neural networks that were trained with the help of a database previously generated by FEM. Identified material properties are compared with data from tensile tests, where available. The influence of irradiation and temperature on the material and fracture behavior is analyzed.

O uso de softwares em projetos de engenharia tem crescido de forma exponencial nos últimosanos. Por serem ferramentas que permitem armazenar e processar grande quantidade de dados,realizar análises numéricas complexas com rapidez, visualizar e simular o comportamento defundações e estruturas, analisando seu desempenho e níveis de segurança, são grandes aliadospara a realização de projetos com qualidade e eficiência com grande importância na área defundações. As fundações superficiais ou rasas transmitem cargas ao terreno devido às pressõesdistribuídas sobre a base da fundação. Dentre os tipos de fundações superficiais usualmenteempregados, encontram-se os radiers. O radier é um tipo de fundação rasa que funciona como umalaje (podendo ser de concreto armado ou protendido) e recebe todos os esforços provenientes dospilares advindos da estrutura. Neste trabalho foi abordado e analisado um projeto real deengenharia de fundações: a construção de um radier (laje sobre o solo) como fundação paratubulações num pátio industrial. Para tal, foi utilizado o SAP2000, para a modelagem do radierbaseado no projeto original para a análise dos momentos gerados na estrutura e verificação datensão do solo.

A cultura data driven, ou seja, se tomar decisões baseadas em dados, têm se tornado cada vez mais forte dentro do mundo corporativo, pois se entende que os dados, transformados em informações, podem ser um balizador para decisões que façam a empresa crescer e economizar custos. Este conceito tem saído do mundo corporativo e sendo inserido no mundo do futebol, onde clubes usam modelos e dashboards para analisar o mercado em busca de jogadores que supram suas carências táticas e melhorar sua performance. Porém, este conceito ainda é embrionário no Brasil, seja pelo fato de que as decisões são tomadas única e exclusivamente pelos chamados “cartolas” (dirigentes de clubes) ou pela falta de recursos para acessar estas tecnologias, dado isto, este trabalho abordará uma nova proposta de mapeamento de mercado de jogadores no futebol brasileiro, usando modelo de clusterização de machine learning, alimentado por dados abertos da internet, para a aproximação de perfis de atletas e trazer a discussão de como pode ser benéfico para aumentar a competitividade de uma equipe.

Com o decorrer dos anos o mundo onde vivemos apresenta um mercado de trabalho cada vez mais competitivo e a visão crítica e a melhoria contínua se fazem necessárias e fundamentais para que as companhias consigam se manter no mercado de trabalho, otimizar processos e diminuir custos da receita do empreendimento. Esse trabalho foi realizado com a finalidade de mover um layout produtivo para uma empresa de desenvolvimento de soluções para abastecimento, localizada na Zona Norte da cidade do Rio de Janeiro-RJ, com o objetivo de aumentar o espaço destinado a produtos com o status de espera, bem como a redução dos deslocamentos realizados dentro da Célula produtiva estudada. O setor produtivo encontra se desorganizado e mal aproveitado, fruto de pouco tempo para análise e estudos de melhoria contínua para o dimensionamento do layout. Com uma estratégia competitiva e necessitando de aumento do espaço para produtos em espera devido à atual irregularidade de fornecimento de produtos imposta ela Pandemia de COVID19, se fez necessário fazer o translado de uma célula produtiva que será descrita nesse trabalho. Conclui-se que apesar dos avanços significativos na otimização dos espaços, ganhos no ciclo produtivo e melhorias em termos de segurança do trabalho, fica evidente que ainda há muito a ser explorado.

Published: February 2024

Modeling is a core practice in science and is a meaningful way to learn the subject. This article introduces a modeling-based approach that highlights the idea that modeling is an iterative process and integrates the fundamental parts of scientists’ work and key suggestions for teaching through modeling. The lesson “The Structure and Function of Kidneys” from a middle school biology course serves as an example of how to conduct the suggested modeling-based approach. By the end of the lesson, almost all students demonstrated a scientific understanding of the structure of nephrons and their functions. On the basis of the implementation of this lesson, we also provide further suggestions for modeling-based teaching.
De las promesas incumplidas de la paz liberal, al liderazgo autoritario en El Salvador

Published: February 2024

El objetivo del artículo es relacionar el ascenso de liderazgos autoritarios en estados que atraviesen fases de posconflicto, por cuenta de las promesas incumplidas de la paz liberal inscritas en los acuerdos firmados para cesar la violencia. Ello, será evidenciado a través del análisis de El Salvador, entre 1992 y 2022, período que cubre la firma del acuerdo de Chapultepec y los primeros tres años del gobierno de Nayib Bukele. Para ello, se emplean tres variables: estancamiento económico, deuda pública y migración; corrupción; violencia e inseguridad. El resultado de la investigación establece cómo el avance de las opciones neoliberales y la preservación de las élites políticas, menoscabó el estado y la institucionalidad —para el caso salvadoreño—, lo que perpetuó el estatus quo y la inequidad; proceso que generó migración y violencia, junto a la llegada de remesas por parte de la diáspora que dejó el país. Asimismo, se resalta cómo estas crisis convergentes, llevaron a un mayor pedido de seguridad por parte de la población, en detrimento de la democracia y las libertades civiles. El trabajo utiliza un marco teórico que identifica las modalidades de paz liberal (esto es, histórica, de centro, y periférica), así como una metodología de estudio de caso que permite encontrar interrelaciones y contextos sobre el problema planteado. Adicionalmente, se articula el desarrollo del texto con un modelo mixto, que aplica el estudio hermenéutico de fuentes secundarias y bases de datos pertenecientes al Banco Mundial (BM), la Organización Internacional para las Migraciones (OIM), Transparency International, Varieties of Democracy (V-Dem) y Latinobarómetro. A manera de conclusión, se resaltan algunos logros en seguridad alcanzados por el gobierno de Bukele, a la vez que se erosiona el estado de derecho, lección que llama la atención sobre el surgimiento de tendencias similares en otros contextos de postconflicto.

Background: Informal carers of people with dementia verbalize guilt. Guilt is a feeling associated with depressive disorder, so the intervention is directed at the global depressive process without defining specific interventions to the phenomenon of guilt. Aims: Our goal was to translate, adapt the language, and evaluate the psychometric properties of the Caregiver Guilt Questionnaire (CGQ) in a Portuguese population sample. Design: An instrumental and cross-sectional study design with a 2week test-retest was used. Methods: A convenience sample of 189 informal caregivers of people with dementia was obtained by non-random sampling. Results: The procedures of the original authors of the CGQ were followed. In the principal components analysis with varimax rotation, five factors stood out, with saturation >40 per item, which explained 65.8% of the total variance. Item 16 was eliminated. Most of the 21 items were grouped differently from the authors. By content analysis we renamed the factors and formed the Portuguese version of CGQ, the QCC. The QCC has good fidelity: alpha Cronbach α = 0.90 and stability with r values of Pearson between 0.93 and 0.99 in test-retest. Conclusion: The analysis of the psychometric properties of the CGQ applied to dementia caregivers sample shows that the Portuguese version is a valid tool.
Transitional justice, a pending subject

Published: February 2024

This article shows important aspects that have to do with Transitional Justice as a pending subject in Mexican Law for social development with a descriptive, critical and analytical methodology that refers to the design of the research, critical observation of problems and analysis of sources of information that will be carried out on the topic in the context of the contemporary Mexican political situation. Several relevant topics are presented with a pluralistic perspective based on traditional justice and the theory of law, with the purpose of exposing how this model of justice works and under what criteria in our country. The first topic is the definition of Transitional Justice, the prevailing need to apply it in Mexican law as well as a current overview of the usefulness of its development to establish a deductive reference framework that allows us to elucidate what the current situation is like. in the life of the nation. Following this, there is a brief and concise contribution on the problems involved in Transitional Justice, as well as the methodological solutions that are presented, as well as the main theoretical approaches to address its study. The way is then clear to expose the topic regarding transitional justice in our country today. In this way, the necessary issues to conclude will be exposed: Transitional justice is located between those who fight against it based on an ideological conception and, on the other side, those who adopt it as a means to implement or consolidate an ideological project of longer range. Transitional justice becomes a tool to generate a connection between justice and peace, generating equality between victims and perpetrators and forming scenarios of compensation and social reconciliation.
