LENOCÍNIO E TRÁFICO DE PESSOAS PARA FINS DE PROSTITUIÇÃO: ANÁLISE SOBRE A VULNERABILIDADE DE GÊNERO E DE RAÇA E O PAPEL DO DIREITO PENAL INTERNACIONAL
Authors: Ribeiro Galarda Gabriela , Ramon Leonardo , Maiara Toniolo Cibelli
Published: August 2023

O presente estudo busca analisar, por meio de uma perspectiva interseccional, o crime de lenocínio, relacionando-o à prática de tráfico de pessoas para fins de prostituição; nesse tema, importante realizar um recorte de classe e raça, buscando demonstrar o ponto de vista de mulheres transexuais, às quais, devido ao preconceito estrutural, muitas vezes, veem a prostituição como única fonte de renda. Ao abordar o tema, necessário compreender o papel que o Direito Penal vem adotando internacionalmente. A partir da pesquisa, demonstra-se a importância de se atentar ao polo passivo do tipo, qual seja, a vítima, enxergando-a não só como estatística, mas principalmente como pessoa já vulnerável perante o sistema, seja por sua raça, classe, orientação sexual ou identidade de gênero. A metodologia utilizada foi a análise doutrinária e dogmática dos temas, demonstrando-se a realidade das mulheres vítimas de lenocínio e tráfico de pessoas por meio de casos concretos apresentados no premiado documentário "Cinderela, Lobos e um Príncipe Encantado" (2008), do diretor Joel Zito Araújo.

Published: August 2023

Introdução: O Infarto Agudo do Miocárdio (IAM) é uma emergência médica comum e potencialmente fatal, representando uma das principais causas de morbidade e mortalidade globalmente. Os marcadores de necrose miocárdica, como a troponina cardíaca e a creatina quinase-MB (CK-MB), desempenham papel crucial no diagnóstico e estratificação de risco do IAM. Metodologia: Foram consultadas bases de dados científicas em três idiomas (inglês, espanhol e português) para selecionar 20 artigos relevantes sobre o tema, publicados nos últimos cinco anos. Resultados e Discussão: A troponina cardíaca foi identificada como o "padrão-ouro" para o diagnóstico de IAM, devido à sua alta sensibilidade e especificidade. Sua dosagem seriada é essencial para identificar pacientes de alto risco, e a CK-MB pode ser útil como marcador complementar em casos específicos. A estratificação de risco e prognóstico baseados nos marcadores de necrose miocárdica são cruciais para a identificação de pacientes com pior evolução clínica e a adoção de abordagens terapêuticas mais intensivas. Pesquisas em novos biomarcadores, como a mioglobina e o BNP, oferecem perspectivas promissoras para aprimorar o diagnóstico e estratificação de risco no IAM. Conclusão: Os marcadores de necrose miocárdica são essenciais para um diagnóstico precoce e preciso do IAM proporcionando uma melhor assistência aos pacientes e redução da morbimortalidade associada a essa condição clínica de alta relevância na cardiologia.

In order to solve the problem of food emergency dispatching under emergencies, a food emergency dispatching method based on the optimal fireworks algorithm was proposed. The fitness function was used to measure the individual merits of fireworks, the tabu table was set to avoid the fireworks algorithm falling into the local optimal, and the tournament strategy was adopted as the iterative strategy of fireworks population. The goal of the fitness function is to maximize the satisfaction of demand points and minimize the vehicle travel time.In order to accurately predict the amount of food required at the point of demand, an infectious disease model (SEIR) was used.By comparing with the basic fireworks algorithm and genetic algorithm, the simulation results show that the proposed algorithm has higher computational efficiency and can be used in food emergency dispatching.

Graphical Image Rendering: Modeling, Animation of Facial or Wild Images
Authors: Kaushik Rohit , Vashisht Chirag , Kaushik Eva
Published: August 2023

In this comparative study, we intend to analyse different methodologies to perform 3-Dimensional modeling and printing, by using raw images as input without any supervision by a human. Since the input consists of only raw images, the foundation of the methods is finding symmetry in images. But the images that seem symmetric are not symmetric due to the perspective effect and utterance of other factors. The method uses factors like depth, albedo, point of view, and lighting from the input image to formulate 3D shapes. A 3D template model with feature points is created, and by deforming the 3D template model, a 3D model of the subject is then reconstructed from orthogonal photos. The number and locations of the proper amount of feature points are derived. Procrustes Analysis and Radial Basis Functions (RBFs) are used for the deformation. Images are then mapped onto the mesh following the deformations for realistic visualization. Characterization of the input image shows an asymmetric cause of shading, lighting, and albedo rendering the symmetry of images. The experiments show that using these methods can give exact 3D shapes of objects like human faces, cars, and cats.

Dimensión de la violencia de género en los procesos de paz
Authors: Casas Godoy María Ruth
Published: August 2023

La necesidad de hablar sobre la construcción de paz implica la presencia de conflictos armados, guerras y descomposición del tejido social originada por diversas formas de violencia. La ausencia de ética y una adecuada educación aleja a la sociedad contemporánea de nociones y conocimientos fundamentales que permiten comprender la importancia del respeto a los derechos humanos, la correcta impartición de justicia, la igualdad, la equidad y la solidaridad.La violencia de género, igual que todo conflicto social, también tiene su origen en la falta de voluntad política para disminuir la violencia. Por el contrario, quienes detentan el poder la legitiman normalizando la constante violación a los derechos fundamentales. Por su parte, la violencia intrafamiliar y de género suscita violencia social y esa violencia estructural genera violencia al interior de las familias. La creación de estrategias que conduzcan al establecimiento de paz positiva es urgente y la inclusión de mujeres en el proceso es fundamental si se considera la necesidad de vincularlo con las teorías críticas de género y la desmitificación de la cultura patriarcal.

Worldwide, family business has gained prominence as one of the critical vehicles for creating employment and hence made a contribution in the efforts to eradicate poverty. However, most family business lack of leadership succession planning, which eventually lead to low levels of performance and lack of sustainability. The purpose of this study was to investigate the relationship between leadership succession planning, performance, and sustainability of family businesses. A qualitative methodological approach was utilized where participants were selected using purposive and snowball sampling methods. Semi-structured interviews were used in collecting data and the collected data was analyzed thematically. The study found that leadership succession planning is linked to sustainability and general performance within family businesses. Conversely, it was found that levels of sustainability and failure of family businesses are related to their inability to come up with effective succession leadership planning. This finding confirms the vital role that leadership succession planning plays in enhancing the performance and sustainability of a family business.

Published: August 2023

In emerging markets, where a substantial number of individuals live below the poverty datum line, status consumption and the desire to purchase luxury products has been increasing. This paper will examine the interrelationships between intrinsic aspirations, extrinsic aspirations, materialism and repurchase intentions of luxury alcohol brands in South Africa. The study followed a quantitative research design and data was collected from 222 participants in South Africa. Data analysis involved structural equation modelling (SEM) performed through AMOS 27 software. The findings of the study showed that there was a statistically significant relationship between extrinsic aspirations and materialism. On the other hand, it was noted that the relationship between materialism and repurchase intentions of luxury alcohol brands was not statistically significant. Similarly, it was noted that the relationship between intrinsic aspirations and materialism was not statistically significant. This study contributes to the understanding of status consumption and shows that extrinsic aspirations have an impact on materialism. Furthermore, marketers and practitioners in emerging markets can draw from the findings of study and note that materialism displayed by consumers does not directly influence the repurchase behaviour of luxury goods.

The Malay Peninsula, comprised of Malaysia, Brunei, Indonesia, and Singapore, is home to the lute-related term gambus. Gambus Hadramauth (Johor Gambus), Hadhrami Gambus (Malaysian Gambus), and Contemporary Gambus are the traditional varieties of Gambus in Malaysia. Gambus, which is renowned for producing music that warms and soothes the spirit, is truly accessible to people of all races and genders. Consequently, the purpose of this study is to follow the evolution of gambus in Malaysia. There are two objectives of the study, which are to study the development of gambus in terms of its physical structure, and then to identify the evolution of gambus from the perspective of its performance practice and repertoire. The research strategy involves qualitative descriptive techniques, in which data is collected through library procedures, analysed depending on the stated problem, and then the findings of the analysis are reported in writing. This study's data comes from scholarly books, theses, and periodicals. According to the findings of the researcher, the performance of gambus is significant to Malays and Muslims; even this musical instrument is viewed as a source of money for performers and producers.

A set of methods to evaluate the below-cloud evaporation effect on local precipitation isotopic composition: a case study for Xi'an, China
Authors: Xing Meng , Liu Weiguo , Hu Jing , Wang Zheng
Published: August 2023

Abstract. When hydrometeors fall from an in-cloud saturated environment toward the ground, especially in arid and semiarid regions, below-cloud processes may heavily alter the isotopic composition of precipitation through equilibrium and non-equilibrium fractionations. If these below-cloud processes are not correctly identified, they can lead to misinterpretation of the precipitation isotopic signal. To correctly understand the environmental information recorded in the precipitation isotopes, qualitatively analyzing the below-cloud processes and quantitatively calculating the below-cloud evaporation effect are two important steps. Here, based on 2 years of synchronous observations of precipitation and water vapor isotopes in Xi'an, China, we compiled a set of effective methods to systematically evaluate the below-cloud evaporation effect on local precipitation isotopic composition. The ΔdΔδ diagram is a tool to effectively diagnose below-cloud processes, such as equilibration or evaporation, because the isotopic differences (δ2H; d-excess) between the precipitation-equilibrated vapor and the observed vapor show different pathways. By using the ΔdΔδ diagram, our data show that evaporation is the major below-cloud process in Xi'an, while snowfall samples retain the initial cloud signal because they are less impacted by the isotopic exchange between vapor and solid phases. Then, we chose two methods to quantitatively characterize the influence of below-cloud evaporation on local precipitation isotopic composition. One is based on the raindrop's mass change during its falling (hereafter referred to as method 1), and the other is dependent on the variations in precipitation isotopic composition from the cloud base to the ground (hereafter referred to as method 2). By comparison, we found that there are no significant differences between the two methods in evaluating the evaporation effect on δ2Hp, except for snowfall events. The slope of the evaporation in proportion to the variation in δ2H (Fi/Δδ2H) is slightly larger in method 1 (1.0 ‰ %−1) than in method 2 (0.9 ‰ %−1). Additionally, both methods indicate that the evaporation effect is weak in autumn and heavy in spring. Through a sensitivity test, we found that in two methods, relative humidity is the most sensitive parameter, while the temperature shows different effects on the two methods. Therefore, we concluded that both methods are suited to the investigation of the below-cloud evaporation effect, while in method 2, other below-cloud processes, such as supersaturation, can still be included. By applying method 2, the diagnosis of below-cloud processes and the understanding of their effects on the precipitation isotopic composition will be improved.
Technical Note: Accurate, reliable and high resolution air quality predictions by improving the Copernicus Atmosphere Monitoring Service using machine learning techniques
Authors: Riccio Angelo , Chianese Elena
Published: August 2023

Abstract. Starting from the regional air quality forecasts produced by the Copernicus Atmosphere Monitoring Service (CAMS), we propose a novel post-processing approach to improve and downscale results on a finer scale. Our approach is based on the combination of Ensemble Model Output Statistics (EMOS) with a spatio-temporal interpolation process performed through the Stochastic Partial Differential Equation-Integrated Nested Laplace Approximation (SPDE-INLA). Our interpolation approach includes several spatial and spatio-temporal predictors, including meteorological variables. A use-case is provided, scaling down the CAMS forecasts on the Italian peninsula. The calibration is focused on the concentrations of several air quality pollutants (PM10, PM2.5, NO2 and O3) at daily resolution from a set of 750 monitoring sites, distributed throughout the Italian country. Our results show the key role played by conditioning variables to improve the forecast capabilities of ensemble predictions, thus allowing a net improvement of the calibration with respect to ordinary EMOS strategies. From a deterministic point of view, the predictive model performance shows a significant improvement of the performance of the raw ensemble forecast, with an almost zero bias, significantly reduced root mean square errors and correlations almost always higher than 0.9 for each pollutant; moreover, the post-processing approach is able to significantly improve the prediction of exceedances, even for very low thresholds, such as those recently recommended by the World Health Organisation. This is particularly significant if a forecasting approach is to be used to predict air quality conditions and plan adequate human health protection measures, even for low alert thresholds. From a probabilistic point of view, the forecast quality was verified in terms of reliability and credible intervals. After post-processing, the predictive probability density functions were sharp, and much better calibrated than the raw ensemble forecast. Finally, we present some additional outcomes based on a set of gridded (4 km x 4 km) daily maps covering the whole Italian country, for the detection of areas where pollution peaks forecasts (exceedances of the regulatory thresholds) occur.
Modelling of cup anemometry and dynamic overspeeding in average wind speed measurements

Abstract. Cup anemometers measure average wind speed in the atmosphere, and has been used for one and a half century by meteorologists. Within the last half century cup anemometers has been used extensively in wind energy to measure wind resources and performance of wind turbines. Meteorologists researched on cup anemometer behaviour and found dynamic overspeeding to be of an inherent and significant systematic error. The wind energy community has strong accuracy requirements for power performance measurements on wind turbines and this lead in the last two decades to new research on cup anemometer characteristics, which was taken to a new level with development of improved calibration procedures, cup anemometer calculation models and classification methods. Research projects in wind energy demonstrated by field and wind tunnel measurements, that angular response was a significant contributor to uncertainty, and that dynamic overspeeding was a significant but less important contributor. Earlier research was mainly made on cup anemometers with hemispherical cups on long arms, and dynamic overspeeding was considered an inherent and high uncertainty on cup anemometers. Newer research on conical cups on short arms showed that zero and low overspeeding at low to medium turbulence intensities is present. Different cup anemometer calculation models were investigated in order to find derived overspeeding characteristics. The general and often used parabolic torque coefficient model show that zero overspeeding is present when the speed ratio roots of the torque coefficient curve go through the equilibrium speed ratio and zero. The two-cup drag model is a special case of the parabolic torque coefficient model, but with the second root being reciprocal to the equilibrium speed ratio. The drag model always results in a positive maximum overspeeding in the order of 1.1 times the turbulence intensity squared. A linear torque coefficient results in maximum overspeeding levels equal to the turbulence intensity squared. Torque characteristics of a cup anemometer with hemispherical cups fits slightly well to the drag model, but a cup anemometer with conical cups do not fit to neither the drag model nor the parabolic model, but better to a partial linear model, and even better to an optimized torque model. Most accurate modelling of cup anemometer characteristics is at present made with the ACCUWIND model. This model uses tabulated torque coefficient and angular response data measured in wind tunnel. The ACCUWIND model is found in IEC wind turbine power performance standards, where it is used in a classification system for estimation of operational uncertainties. For an actual comparison of two cup anemometers, with hemispherical and conical cups respectively, the influence of dynamic overspeeding was found to be relatively low compared to angular response, but for conical cups it was specifically low.

Abstract. Recent research studies have significantly contributed in understanding physical mechanisms associated with the occurrence of Marine Heatwaves (MHWs). Building upon prior research, this study investigates the relative role of air-sea heat exchange and oceanic processes during the onset and decline phases of surface MHWs in the Mediterranean Sea, based on a joint analysis of remote sensing data and reanalysis outputs over the period 1993–2022. Our findings suggest that oceanic processes play a key role in driving SST anomalies during MHWs, as 44 % of the onset and only 17 % of the decline phases are primarily driven by surface heat fluxes. The role of surface fluxes becomes more important during warmer months and onset periods. Spatially, their contribution is greater in the Adriatic and Aegean sub-basins, where they become the major driver of most onset phases. Latent heat emerges as the most significant heat flux component in forming the SST evolution, across all seasons. Onset/decline phases lasting less than 5 days experience a weaker contribution of heat fluxes, compared to longer phases (lasting 5–10 or more than 10 days). Moreover, an inverse relationship between MHW severity and the contribution of heat fluxes is observed. At the subsurface, mixed layer shoaling is found over the entire duration of most MHWs, particularly for those of shorter duration. Therefore, the surface cooling right after the peak day is likely not associated with vertical mixing in such cases. These findings suggest that other oceanic processes, potentially horizontal advection, have key role in modulating SST at the beginning of most MHW declines. In turn, further dissipation of heat is commonly driven by vertical mixing, as indicated by a significant mixed layer deepening after the MHW end day in most cases. This study emphasizes the need for considering subsurface information for future studies of MHWs and highlights the importance of accounting for limitations associated with the definitions employed for MHW phases.
Is the North West European Shelf becoming more stratified with the occurrence of marine heatwaves?
Authors: Chen Wei , Staneva Joanna
Published: August 2023

Abstract. Marine heatwaves (MHWs) are characterized by anomalous and prolonged increases in sea surface temperatures, driven by atmospheric and oceanic factors. The intensification of MHWs is an evident consequence of ongoing global climate change. The question of whether the North West European Shelf (NWES) is experiencing increased stratification in recent decades is of significant interest in understanding the impacts of these extreme events. In this study, we leverage ocean physics reanalysis data obtained from Copernicus Marine covering the temporal span from 1993 to 2023 to conduct a rigorous examination of the NWES domain. The focus centers on the assessment of potential energy anomaly (PEA) and its role in shaping stratification dynamics. Our findings reveal an increase in both the frequency and duration of MHWs in the NWES area, especially in coastal areas where the duration of MHWs is increasing the fastest, generally by more than 2 days per year over the study period. However, despite the intensified MHWs, thermal stratification in the NWES is weakening, particularly in the middle and northern North Sea. This suggests that the warming effect due to MHWs is insufficient to counteract the overall decline in thermal stratification caused by global warming. Additionally, our study highlights the significance of seawater salinity in driving the trend of density stratification. Specifically, the discharge from the Baltic Sea plays a crucial role in influencing the stratification patterns in the North Sea region. The outcomes of this research transcend theoretical confines, bearing practical significance for diverse sectors. By unravelling the intricate interplay between MHWs, thermal stratification, and salinity dynamics, our study contributes to a more comprehensive understanding of climate change impacts on regional oceanic systems. The implications extend to domains such as ecosystem dynamics, fisheries, and related sectors, which are poised to be influenced by the enduring alterations in thermal stratification patterns that have far-reaching implications for the ecological and socio-economic fabric of the NWES region.
