Abstract A certificate is evidence of participating in a process, and anyone who holds a certificate is believed to have the prerequisites necessary to handle what the certificate qualifies them for. However, this perception might be incorrect if the certificate has been obtained by taking shortcuts. (Objective) In this paper, a compartmental model was developed to quantify factors that could put the authenticity of a certificate in doubt by examining the trade-off between academic standards and failure rates in the context of tertiary education institutions in Nigeria. (Methodology) The model was validated using several mathematical theorems. Equilibria for the model and the threshold for acceptable academic performance were derived. Stability analysis was carried out by using the stability theory of differential equations based on the derived acceptable academic performance threshold. (Results) The theoretical results for the model were validated through numerical simulations, and the results from the simulations linked acceptable failure rates to academic performance falling below the threshold of the institutions’ standards. (Conclusions) The policy implication of the result is that an increase in the supply of qualified graduates into Nigeria’s labor markets, as well as a reduction in the rate of unemployment, is a function of maintaining academic standards.

Abstract The United Nations claims that education is a crucial element in reducing poverty rates in any country if it is accessible, adaptable, acceptable, and affordable; known as the 4A’s of education, which are considered within the national education policy. This paper analyzes the effect of the 4A’s of education on multidimensional moderate-income poverty and extreme income poverty in Mexico in the years 2010 and 2020. This is achieved with the analysis of microdata from the Module of Socioeconomic Conditions of the National Survey of Household Income and Expenditure (MCS - ENIGH) 2010 and 2020 and with dichotomous logit models. The results indicate that the 4A’s have a greater effect on the reduction of multidimensional extreme income poverty than on moderate, even over different periods.

Resumen La Organización de las Naciones Unidas expone que la educación es un elemento crucial para disminuir los índices de pobreza de cualquier país si ésta es: accesible, adaptable, aceptable y asequible; conocidas como las 4A´s de la educación, las cuales están consideradas dentro de la política educativa nacional. El presente documento analiza el efecto de las 4A´s de la educación en la pobreza multidimensional moderada por ingresos y pobreza extrema por ingresos en México en los años 2010 y 2020. Lo anterior se logra con el análisis de microdatos del Módulo de Condiciones Socioeconómicas de la Encuesta Nacional de Ingresos y Gasto de los Hogares (MCS - ENIGH) 2010 y 2020 y con modelos dicotómicos tipo logit. Los resultados indican que las 4A´s tienen un efecto mayor en la reducción de la pobreza multidimensional extrema por ingresos que en la moderada, incluso en distintos periodos.

Abstract The paper aims to analyze how democracy is structured within the neoliberal capitalist system in the Brazilian context. While neoliberalism requires market liberalization, reduction of the social state, and financialization of life, democracy presupposes political and economic equality, public apparatus, and inclusion; thus, it is necessary to discuss this conflicting relationship. The first session of the work discusses the economic, political, and social system of neoliberalism, understanding its requirements and characteristics, as opposed to democratic pretensions, to enter into Brazilian particularities. The second topic analyzes the construction of a neoliberal society in the country, establishing the investigation through the clash between social development and neoliberal advancement in Brazil. Finally, it examines the presence of neoliberal capitalism from the Partido dos Trabalhadores (PT) governments to the first two years of the Bolsonaro government, questioning the place of democracy. For this, the research used the deductive approach method and type of bibliographical and documentary research with a qualitative approach. In conclusion, we highlight the obstacle that neoliberalism imposes to realize a substantial, egalitarian, and plural democracy, marginalizing its power and restricting it to the electoral sphere. context liberalization state life equality apparatus inclusion thus relationship characteristics pretensions particularities country Brazil Finally PT (PT government conclusion substantial egalitarian sphere

ABSTRACT The macroeconomic approach is a way of analyzing and studying issues related to the global analysis of the economy. The objective of this paper is to estimate the influence of macro- economic determinants on the achievement of the monetary poverty reduction targets in Paraguay during the period 1997-2020. It works specifically with the first two targets that have to do with the eradication of extreme poverty and the reduction to 50% of total poverty. The macroeconomic determinants analyzed are GDP, CPI, the Gini index and social spending. For this purpose, we propose the application of an econometric model which, based on regression models, allows us to calculate the incidence of each of the variables analyzed on monetary poverty. In addition, projections are made to infer whether or not the objectives of SDG 1 can be met and under what conditions. The results obtained allow us to affirm, on one hand, that all the determinants analyzed have a significant impact on monetary poverty and, on the other hand, allow us to infer that none of the targets can be met by 2030, either by maintaining constant or even increasing economic growth. This leads to the conclusion that the effectiveness of poverty reduction strategies lies in combining efforts that link GDP growth with equitable redistribution of resources and social investment.

RESUMEN Este trabajo tiene como objetivo estimar la influencia de los determinantes macroeconómicos en la consecución de las metas de reducción de pobreza monetaria en Paraguay durante el período 1997-2020. Los determinantes macroeconómicos analizados son el PIB, el IPC, el índice de Gini y el gasto social. Para el efecto, se propone la aplicación de un modelo econométrico, el cual, a partir de modelos de regresión, permite calcular la incidencia de cada una de las variables analizadas sobre la pobreza monetaria. Además, se realizan proyecciones para inferir si se pueden cumplir o no con los objetivos del ODS 1 y bajo qué condiciones. Los resultados obtenidos permiten afirmar, por un lado, que todos los determinantes analizados inciden significativamente sobre la pobreza monetaria y, por otro lado, permiten inferir que ninguna de las metas se puede cumplir al 2030, ya sea manteniendo constante o incluso aumentando el crecimiento económico. Esto permite concluir que la eficacia en las estrategias de reducción de pobreza radica en combinar esfuerzos que vinculen el aumento del PIB con la redistribución equitativa de recursos y la inversión social.

Resumen: Este trabajo aborda la transformación productiva y la nueva actualidad de las políticas industriales en América Latina, haciendo referencia a un nuevo desarrollismo. Se reflexiona sobre la transformación productiva de la región, cuyo estancamiento de productividad se basa en una desindustrialización prematura y la ausencia de cambio estructural, lo que contrasta con las experiencias exitosas del Sudeste Asiático. Frente al renacimiento de las políticas industriales, se señala que las nuevas políticas de transformación productiva deben considerar cuatro tipos de coordenadas fundamentales: cambio climático y reducción de emisiones, digitalización manufacturera o industria 4.0, nuevas autonomías y acortamiento de cadenas, e inclusión social. Se postula que, con base en las lecciones aprendidas y analizando los obstáculos desde una perspectiva estructuralista, se podrá avanzar en torno a un nuevo consenso sobre una propuesta para la transformación productiva con una perspectiva de integración regional.

Abstract: In this paper we discuss the productive transformation and the new relevance of industrial policy in Latin America with reference to a new developmentalism. We reflect on the productive transforma-tion of the region, where the stagnation of productivity is due to premature deindustrialization and the absence of structural change, in contrast to the successful experience of Southeast Asia. Given the renaissance of industrial policy, it is argued that the new policy for productive transformation should take into account four types of fundamental guidelines: climate change and emissions reduction, digitalization of production or Industry 4.0, new autonomies and shortening of chains, and social inclusion. We assume that, based on the lessons learned and the analysis of the obstacles from a structuralist perspective, it will be possible to find a new consensus for a productive transformation proposal with a regional integra-tion perspective.

Abstract The aim of this paper is to examine the effect of economic openness on wage dispersion. To this end, using a fixed effects panel model, we evaluate the impact of exports and foreign direct investment (FDI), as well as productivity and education, on wage dispersion in 14 economic subsectors in Mexico during the period 1999-2021. The main findings show that: i) increasing exports tend to diminish wage dispersion; ii) the flow of FDI seems to increase wage dispersion; iii) productivity and the heterogeneity of the productive network are determining factors in the dynamics of average wages. In this context, it is important to implement a variety of industrial and labour policies to effectively absorb the dynamic advantages associated with economic openness, such as the reduction of wage dispersion.

Resumen El objetivo de esta investigación es analizar el efecto de la apertura económica en la dispersión salarial. Con este fin, mediante un modelo panel de efectos fijos, evaluamos el impacto de las exportaciones y la inversión extranjera directa (IED), así como de la productividad y la educación, sobre la dispersión salarial en 14 subsectores económicos de México durante el periodo 1999-2021. Los resultados principales muestran que: i) el incremento de las exportaciones reduce la dispersión salarial; ii) el flujo de IED parece inducir un aumento de la dispersión salarial; iii) la productividad y la heterogeneidad de la malla productiva constituyen factores determinantes de la dinámica de las remuneraciones medias. En este contexto, es importante instrumentar una miscelánea de política industrial y laboral que permita absorber en forma efectiva las ventajas dinámicas asociadas con la apertura económica, como la reducción de la dispersión salarial.

Abstract: Digital mammogram plays a key role in breast cancer screening, with microcalcifications being an important indicator of an early stage. However, these injuries are difficult to detect. In this paper, we propose a lightweight Convolutional Neural Network (CNN) for detecting microcalcifications clusters in digital mammograms. The architecture comprises two convolutional layers with 6 and 16 filters of 9×9, respectively at a full scale, a global pooling layer that eliminates the flattening and dense layers, and a sigmoid function as the output layer for binary classification. To train the model, we utilize the public INbreast database of digital mammograms with labeled microcalcification clusters. We used data augmentation techniques to artificially increase the training set. Furthermore, we present a case study that encompasses the utilization of a software application. After training, the resulting model yielded an accuracy of 99.3% with only 8,301 parameters. This represents a considerable parameter reduction as compared to the 67,797,505 used in MobileNetV2 with 99.8 % accuracy.

Abstract: Processing, visualizing and understanding data from meteorological networks can present several challenges due to the variety and complexity of the data and must be accessible in real time and in different formats, protocols and standards. This paper presents the development of an innovative technological framework for handling heterogeneous climatological data in a NoSQL environment. The framework was developed following the Action Research methodology and enables the extraction of heterogeneous data, their homogenization, and the creation of a dataset. Its real-case application took place in data repositories used for climatological data management in a specialized regional center in Ciudad Juarez, Mexico. The main repository use MongoDB and contain 631,202 documents with data from several meteorological stations. A 70% reduction in data processing time is evidence that the methodology and framework developed were effective in the case of the application. In addition, the generated data sets are homogenized and in formats compatible with advanced analysis tools.

SYNOPSIS Ferrochrome (FeCr) is a vital ingredient in stainless steel production and is commonly produced by smelting chromite ores in submerged arc furnaces. Silicon (Si) is a componrnt of the FeCr alloy from the smelting process. Being both a contaminant and an indicator of the state of the process, its content needs to be kept within a narrow range. The complex chemistry of the smelting process and interactions between various factors make Si prediction by fundamental models infeasible. A data-driven approach offers an alternative by formulating the model based on historical data. This paper presents a systematic development of a data-driven model for predicting Si content. The model includes dimensionality reduction, regularized linear regression, and a boosting method to reduce the variability of the linear model residuals. It shows a good performance on testing data (R² = 0.63). The most significant predictors, as determined by linear model analysis and permutation testing, are previous Si content, carbon and titanium in the alloy, calcium oxide in the slag, resistance between electrodes, and electrode slips. Further analysis using thermodynamic data and models, links these predictors to electrode control and slag chemistry. This analysis lays the foundation for implementing Si content control on a ferrochrome smelter.

ABSTRACT: As an essential way to enhance farmers’ self-development ability, off-farm employment plays an indispensable role in farmers’ multidimensional poverty reduction in many countries. Employing a survey of 1926 farmers in five provinces of the Yellow River Basin in China, this paper examined the multi-dimensional poverty reduction effect of off-farm employment and the heterogeneous influence of different dimensions of off-farm employment (modes, levels, distances and frequency). The results showed that (1) although absolute poverty in the income dimension was largely eliminated in the Yellow River Basin, the poverty in social resources, transportation facilities, employment security were the key bottlenecks restricting farmers’ self-development. (2) The province with the best multidimensional poverty reduction effect for non-farm employment was Shaanxi, with the largest contribution to employment security. (3) Improving off-farm employment level, distance and time can significantly alleviate the multi-dimensional poverty of farmers. Therefore, to lessen the multi-dimensional poverty of farmers in the Yellow River Basin, it is necessary to focus on the governance of multi-dimensional key poverty-stricken areas, such as the middle and upper courses of the Yellow River, adopting multidimensional poverty alleviation strategy of off-farm employment according to local conditions, working on the farmers’ deficiencies in social resources, mobility, employment security, and deepening the effect of off-farm employment on benefiting farmers and helping the poor.

RESUMO: Como uma forma essencial de aumentar a capacidade de autodesenvolvimento dos agricultores, o emprego fora da fazenda desempenha um papel indispensável na redução da pobreza multidimensional dos agricultores em muitos países. Empregando uma pesquisa com 1926 agricultores em cinco províncias da Bacia do Rio Amarelo na China, este documento examina o efeito multidimensional de redução da pobreza do emprego e a influência heterogênea de diferentes dimensões do emprego fora da fazenda (modos, níveis, distâncias e frequência). Os resultados mostram que (1) embora a pobreza absoluta na dimensão da renda tenha sido em grande parte eliminada na Bacia do Rio Amarelo, a pobreza em recursos sociais, facilidades de transporte e segurança no emprego são os principais gargalos que restringem o autodesenvolvimento dos agricultores. (2) A província com o melhor efeito multidimensional de redução da pobreza para o emprego não agrícola foi Shaanxi, com a maior contribuição para a segurança no emprego. (3) A melhoria do nível de emprego fora da fazenda, distância e tempo pode aliviar significativamente a pobreza multidimensional dos agricultores. Portanto, para diminuir esta pobreza é necessário concentrar-se na governança de áreas-chave multidimensionais atingidas, tais como os cursos médio e superior do Rio Amarelo, adotando uma estratégia multidimensional de redução da pobreza de emprego fora da fazenda de acordo com as condições locais, trabalhando nas deficiências dos agricultores em recursos sociais, mobilidade, segurança no emprego e aprofundando o efeito do emprego fora da fazenda em benefício dos agricultores e ajudando os pobres.

Abstract This paper will propose an innovative compact, low-cost, low-profile inverted U-shaped patch antenna with a single and dual band-notched ultra-wideband (UWB) with split ring resonators (SRRs). To achieve our main goal based on the reduction of electromagnetic interference in narrowband communications (WLAN, WiMAX, and satellite), four-element rectangular split-ring resonators (SRRs) array are placed nearby the feedline to create notch band at approximately 5.15-5.35 and 5.725-5.85 GHz. The SRRs antenna's measured data indicate a directivity of 8.52 dBi, a gain of 7.18 dBi, a reflection coefficient of -27 dB, and an efficiency of 84.3%. The realized prototype, including the SRRs and CSRRs structures, were carried out using a PCB prototyping machine. Reflection coefficient measurement is obtained using a vector network analyzer (VNA) PNA-X from Agilent Technologies. The measured values of the proposed antenna, with 50 x 38 x 1.6 mm3 in total and constructed on a FR4 substrate with permittivity of ɛr = 4.3, loss tanδ = 0.0024 and substrate thickness of h = 1.6 mm, correlate well with the simulated values.

Abstract Design loads for parking garages should be reviewed every few years due to changes in fleet characteristics and the impact of design loads on carbon emissions by the built environment. Specifically for Brazil, the authors are unaware of existing studies to justify the design values and corresponding exceedance probabilities stated in NBR 6120:2019 - Design Loads for Structures. In this paper, a simplified probabilistic model for live loads in parking garages is presented. A set of updated statistics characterizing the gross curb weight of the fleet in circulation was obtained based on technical specifications and sales reports between 2003 and 2022. These statistics and the probabilistic load model are employed to derive the equivalent uniform design load corresponding to a 30% probability of being exceeded in 50 years, according to the definition stated in NBR 6120:2019 and NBR 8681:2003. The results provide support for a significant reduction of the current design load for light-duty vehicle parking garages, from the current 3.0 kN/m2 to at least 2.5 kN/m2. Such a reduction has a significant impact on new building construction costs and carbon emissions and would not compromise the structural safety of parking garages built in Brazil. environment Brazil 61202019 6120 2019 6120:201 Structures paper presented 200 2022 30 5 86812003. 86812003 8681 2003. 8681:2003 lightduty light duty 3 0 3. kNm2 kNm kN m2 m kN/m 25 2 2. 6120201 612 201 6120:20 20 202 8681200 868 8681:200 612020 61 6120:2 868120 86 8681:20 61202 6 6120: 86812 8 8681:2 8681:

Resumo Cargas de projeto para garagens devem ser periodicamente revisadas em função de mudanças nas características da frota de veículos, bem como devido ao impacto nas emissões de carbono do ambiente construído. Especificamente no caso do Brasil, os autores desconhecem estudos que justifiquem os valores de projeto e as probabilidades de excedência preconizados na NBR 6120:2019 - Ações para o cálculo de estruturas de edificações. Neste artigo, um modelo estocástico simplificado para cargas variáveis em garagens e estacionamentos é apresentado. Com base nas especificações técnicas dos veículos e em dados de vendas entre 2003 e 2022, foram obtidas estatísticas para caracterizar os pesos operacionais da frota de veículos em circulação. Estas estatísticas e o modelo probabilístico são utilizados para obter a carga uniforme equivalente que corresponde à probabilidade de 30% de ser ultrapassada em 50 anos, conforme a definição da NBR 6120:2019. Os resultados obtidos fornecem suporte para uma redução na carga de projeto para garagens, dos atuais 3.0 kN/m2 para pelo menos 2.5 kN/m2. Tal redução teria um impacto significativo no custo de novos edifícios-garagem/estacionamentos subterrâneos, bem como nas emissões de carbono, sem comprometer a segurança destas estruturas. construído Brasil 61202019 6120 2019 6120:201 edificações artigo apresentado 200 2022 circulação 30 5 anos 61202019. 2019. 3 0 3. kNm2 kNm kN m2 m kN/m 25 2 2. edifíciosgaragem/estacionamentos edifíciosgaragemestacionamentos edifícios garagem/estacionamentos garagem subterrâneos 6120201 612 201 6120:20 20 202 edifíciosgaragem garagemestacionamentos 612020 61 6120:2 61202 6 6120:

Abstract The production of eco-efficient cement-based materials is essential to reduce CO2 emissions from the construction industry. A substantial reduction in global CO2 emissions can be achieved by using clinker in mortar and concrete more efficiently and using low-CO2 minerals as partial replacements for Portland cement. However, the proportioning of eco-efficient composites is complex and the reduction in clinker content may affect its properties. This paper aims to optimize the mix design of high-strength mortars containing supplementary cementitious materials (limestone filler, fly ash, metakaolin, silica fume). The compressible packing model associated with a simplex mixture design were used together with chemical parameters, to limit the amount of active SCMs for the model iterations. The results show a significant decrease in the environmental impact of the mortars, which presented compressive strengths between 76 and 118 MPa at 91 days and binder indexes between 10 and 15 kg/m3/MPa. The reactivity of the SCMs (based on the modified Chapelle test) were successfully used to establish the Portland cement substitution (up to 13%), preventing the presence of unreacted SCMs and optimizing the use of limestone filler and sand, which have a lower environmental impact. The high-performance blends reached 8.73 kg CO2e/MPa, up to a 30% reduction in CO2e emissions compared to the mortar with only Portland cement. ecoefficient eco efficient cementbased based CO industry lowCO2 lowCO low low-CO However properties highstrength high strength ash metakaolin fume. fume . fume) parameters iterations 7 11 9 1 kgm3MPa kgmMPa m3 m kg/m3/MPa test 13%, 13 13% , 13%) sand highperformance performance 873 8 73 8.7 CO2eMPa COeMPa e CO2e/MPa 30 COe kgm 87 8. eMPa 3

Resumo A produção de materiais ecoeficientes à base de cimento é essencial para reduzir as emissões de CO2 na indústria da construção civil. Pode-se alcançar reduções importantes nas emissões globais de CO2 pelo uso mais eficiente do clínquer em argamassas e concretos, e pela utilização de adições minerais de baixo teor de CO2 como substitutos parciais do cimento Portland. No entanto, a dosagem de compósitos ecoeficientes é complexa e a redução do teor de cimento pode afetar suas propriedades. Este artigo tem como objetivo otimizar a dosagem de argamassas contendo adições minerais (fíler de calcário, cinza volante, metacaulim, sílica ativa). O modelo de empacotamento compressível associado a um planejamento de mistura simplex foi utilizado juntamente com parâmetros químicos, para limitar a quantidade de adições minerais reativas para as iterações do modelo. Os resultados mostram uma redução significativa no impacto ambiental das argamassas, que apresentaram resistências à compressão entre 76 e 118 MPa aos 91 dias e índices de ligante entre 10 e 15 kg/m3/MPa. A reatividade das adições minerais (baseada no teste de Chapelle modificado) foi utilizada com sucesso para estabelecer a substituição do cimento Portland (até 13%), evitando a presença de adições minerais sem reagir e otimizando o uso de fíler calcário e areia, que apresentam menor impacto ambiental. As misturas de alto desempenho atingiram 8,73 kg CO2e/MPa, redução de até 30% nas emissões de CO2 comparativamente às argamassas contendo apenas cimento Portland.

ABSTRACT The purpose of this paper is to prioritize which waste should be treated by Lean Healthcare in a medical clinic of a middle-sized Brazilian hospital, using the multicriteria decision support method THOR 2. It focusses on structuring the problem, establishing alternatives through the study hospital and Lean interventions already made in it, and determining the criteria and parameters of THOR 2 with the help of Value Focus Thinking (VFT) and the hospital directors. THOR 2 was able to identify, taking into account its preference relationships in S2, that establishing a Kanban within the hospital’s medical clinic is the preferred and the main contribution and novelty to the literature is the way that multicriteria methods can help in Lean Healthcare decision making. As conclusions, it was possible to establish a prioritization order, maintaining the concept of continuous improvement, arising from Lean Healthcare, while respecting the limits and restrictions of the hospital. middlesized middle sized problem VFT (VFT directors identify S2 S hospitals s making conclusions order improvement

Abstract This paper presents the strategies and initial implementations of a data culture conversion process at a company in the electricity sector. Solutions are being developed within the scope of the construction management macro-process, which involves multiple sectors of the company, as well as external agents. The strategy is based on implementing Proofs of Concept as tools for converting the data culture within the company and, at the same time, supporting the essential activities of construction management. The proofs of concept aligned with the change in data culture have two components: technology and people. The first consists mainly of intelligent automation and process optimization. The second component involves sensitization, training and developing solutions together with the company's employees. The results involve a reduction in workload since some activities have been partially or totally transferred to the software. Greater assertiveness in estimating numerical data, such as prices and budgets. Increased reliability by reducing human intervention and complex calculations. Greater controllability by monitoring multiple activities and sectors, simplifying management. Finally, the integration of technology and people has shown significant advances in organizational culture, enabling employees to have a greater understanding of advanced tools and methods and to be able to identify opportunities and share solutions within the company. sector macroprocess, macroprocess macro process, macro-process agents time components optimization sensitization companys s software budgets calculations Finally
