Authors: Castañeda Garza Diego
Published: November 2023

This article presents the first complete 19th-century reconstruction of the Mexican wealth distribution, from independence to the Mexican Revolution. It uses an often underutilized source in Mexican historiography: will inventories/protocols. In addition, the present article estimates the levels and trends of historical wealth inequality using five different methods, among them the novel application of the properties of two theoretical parametric distributions to the measurement of historical inequality. The dynamics of wealth inequality in 19th century Mexico were dominated by the top 5% and the middle 40% of the wealth distribution; meanwhile, the top 10% and bottom 40% demonstrate remarkable stability. This article's main contributions are the reconstruction of historical wealth inequality combining classic and new methods, the examination of the distributive forces and their dynamics in a changing political economy environment and analyzing the historical developments in light of their potential effect on the distribution of economic resources.

The disregard for the spiritual dimension of children, particularly within the contemporary technological era, contributes significantly to the erosion of ethical values within familial domains. Therefore, the spiritual formation of children must be emphasized by parents, with a particular emphasis on mothers, who occupy the most proximate role in their children's lives. The exemplary source of spiritual formation is the teachings of Prophet Muhammad (PBUH), as he is the best example to follow in family life. Thus, this study aims to extract hadiths from Sahih al-Bukhari regarding the role of mothers in shaping the spiritual development of children. The extracted hadiths will be analyzed to identify the contextual meanings of these hadiths. This study employed the qualitative method based on the text analysis approach using the extraction of hadiths related to the role of mothers from Sahih al-Bukhari, applying the Theory of Semantic Fields (SFT) for the term "umm" (mother). This theory is applied to identify hadiths related to the role of mothers based on the term "umm" and its synonyms, antonyms, hypernyms, and meronyms. The result of the study shows a total of 5 hadiths directly related to the spiritual formation of children. These 5 hadiths encompass aspects of instilling faith, adopting an approach to train children in performing worship, and praying for children. In conclusion, spiritual formation within children, guided by the hadiths of the Prophet Muhammad, peace be upon him, serves as a comprehensive guide to shaping their character and nurturing them into pious individuals.

Usually, duty as a preacher is pioneered by a group of individuals with Islamic studies backgrounds. This is because as a preacher, they have to guide the individual spiritually when needed. Therefore, it is a must for a group of preachers to have a wide knowledge of Islamic studies. However, there is also a group of preachers who have standard knowledge or only know the basics of religion but are active in preaching. This intended group is made up of former drug users who have contributed devotion, time, and energy to making drug addicts awake to the nature of God and faith. Because this contribution of devotion is a challenging task and not so popular, this research is intended to study the main factors contributing to their hard work in delivering preaching for this group of active drug addicts. After that, every factor that has been found will be debated according to the hadith perspective. Thematic methods are used in this research to analyse the data that has been obtained through data collection methodology and an interview with the preacher. The obtained data will be analysed using thematic methods and NVIVO software. The results show that there are 7 reasons that contribute to and motivate preaching: get busy to control addiction; advise others as well as yourself; reduce longing for drugs; get close to religion; help others in need; experience makes them understand active drug users; and also make up for old mistakes that surround people in drug addiction.
The Acculturation and Adaptation of Syrian Refugee Students: A Systematic Review of the Literature
Authors: Şeker Betül Dilara , Sirkeci Ibrahim
Published: November 2023

In the contemporary landscape, we confront the global refugee crisis, a complex phenomenon rooted in a confluence of political, economic, and social factors. Refugees are compelled to immerse themselves in unfamiliar cultures, often markedly distinct from their places of origin. As they navigate the intricacies of integrating into novel social and cultural milieus, the concepts of acculturation and adaptation assume paramount significance, particularly within the sphere of education. The primary objective of our review paper is to provide a meticulous and systematic examination of academic studies undertaken to illuminate the experiences and outcomes of the acculturation and adaptation processes among Syrian refugee students in Turkey. To accomplish this, we conducted comprehensive keyword searches across ten English-language databases and three Turkish-language databases. In the initial sweep of the literature, we identified a total of 591 pertinent studies. Subsequently, following rigorous scrutiny, we selected and included 14 full-text articles, authored in both English and Turkish, spanning the period from 2011 to 2022, for our analysis. These fourteen articles were assessed and reported in accordance with the PRISMA criteria. Our analysis of the available sources revealed that language proficiency emerged as the most pivotal variable influencing educational outcomes and adaptation to the host culture. Indeed, our findings underscore the pivotal role that educational institutions play in facilitating the acculturation and adaptation of Syrian refugee students.
Social-integration courses serve as a bridging function for migrants by increasing peer support and life learning opportunities
Authors: Kiliç Emel
Published: November 2023

Although migration and people’s encounters with other cultures are significant life events, factors that influence migrants’ relationships with host countries remain understudied. This study examined the socio-cultural integration of Turkish-speaking migrants in Belgium from their perspective, using a holistic approach for participants to share their stories. Fifty-nine Turkish-speaking migrants with different religious, national, and regional backgrounds who attended common classes in a (mixed) social integration course in Antwerp participated in the study. They were subdivided into six focus groups for interviews, which allowed participants to deconstruct their knowledge of local people, their subjective beliefs, and prejudices that separated them from other cultures. We found the focus-group interviews to be valuable interventions in the integration process. The study recommends that those who organise integration courses for migrants should approach this process with kindness, empathy, and an open mind.
Análisis del rendimiento de luminancias relativas de acabados de láminas metálicas con fotografías digitales

Published: November 2023

El sobrecalentamiento por cubierta causado por altos niveles de radiación solar es especialmente intenso en cubiertas metálicas. El aumento de la reflectancia del acabado superficial en las cubiertas ha demostrado ser una estrategia de control térmico, por lo que el presente estudio propone una metodología para conocer el comportamiento de las reflectancias solares de acabados comunes para láminas metálicas, mediante el seguimiento de sus luminancias relativas (LR) obtenidas por medio de imágenes de mapa de bits capturadas con una herramienta convencional como una cámara fotográfica digital. Para ello se dispuso de una escena con 8 muestras de láminas metálicas con los acabados objeto de estudio - incluidos blancos de conocida reflectancia solar alta - en condiciones de intemperie para comprobar el comportamiento de sus luminancias respecto a una muestra de referencia de color blanco. Se ingresaron las fotografías capturadas a lo largo de 10 meses en un software programado con este propósito pudiendo evidenciar que los acabados blancos conservaron sus niveles de LR a lo largo del estudio, no así el resto de los acabados, los cuales presentaron una disminución moderada de sus LR respecto a la muestra de referencia. Se concluye que el uso exterior de acabados blancos en cubiertas metálicas es una estrategia adecuada de control térmico ya que son capaces de conservar sus niveles de reflectancia solar por periodos de tiempo relativamente prolongado sin demandar un mantenimiento constante.

This study aims to analyze economic development towards improving the quality of human life in the Special Region of Yogyakarta from 2013 to 2019. Theoretically, the Human Development Index (IPM) measures human resources and is used as a standard indicator of human welfare. The HDI indicator is based on the quality of health, education and people's purchasing power. An increase in the HDI value indicates that there has been an increase in human welfare and rate in an area. Human Development Index (IPM) is the dependent variable, while capital expenditure, poverty, Regional Minimum Wage (UMP), and Gross Regional Domestic Product (GRDP) are independent variables. The research approach uses a fixed effect model: panel data. Partial research results show that capital expenditure has a positive but not significant effect on HDI, while poverty has a negative and insignificant influence on HDI. In addition, UMP and GRDP have a significant positive impact on HDI. Simultaneously, poverty, capital expenditure, UMP and GRDP substantially influence the HDI in the Special Region of Yogyakarta.

Keywords: Human Development Index, Poverty, Provincial Minimum Wage, Government Expenditure, Gross Regional Domestic Product.

The microstructure, tensile and fatigue properties of a martensitic stainless steel (MSS) plate with a thickness of 0.152 mm are investigated in this study. The microstructural properties were initially studied using electron backscatter diffraction microscopy. High dislocation densities were observed in the microstructure, along with the rolling texture revealed by the pole figure, following an initial cold rolling process of the as-received MSS plate. Tensile tests were conducted in both the rolling and transverse directions to compare the strength of the material in both directions. The results showed that the tensile strength was relatively low in the rolling direction. This can be attributed to the microstructure and crystallographic orientation of the material along that direction. Additional tensile tests were performed at various temperatures within the operating temperature range in the rolling direction. The results indicate that the highest tensile strength and elastic modulus are observed at room temperature. A high-cycle fatigue test was performed to determine the fatigue limit of the MSS plate. Furthermore, the microstructure was analyzed by controlling the fatigue cycles within the same stress range. The results revealed a proportional relationship between the accumulated deformation within the grains and the fatigue cycles. This can be helpful in understanding the fatigue damage mechanisms of the MSS plate.

SnSe2 alloys have been investigated in recent times as potential n-type thermoelectric materials. In this study, the thermoelectric transport properties of a series of Sb-doped SnSe2, Sn(Se1-xSbx)2 (x = 0, 0.015, 0.03, 0.045, 0.06) alloys are investigated. The electrical conductivity was generally enhanced with Sb doping owing to a large increase in electron concentration. However, the Seebeck coefficient largely decreased with doping. Consequently, the power factor was significantly lower at a low doping of x = 0.015, and then began rising as the doping was increased beyond x = 0.015. It was found that the density-of-states effective mass and weighted mobility decreased with Sb doping, implying that the electrical transport properties of SnSe2 were degraded by Sb doping. The total and lattice thermal conductivities gradually decreased due to additional point defect scattering. Thus, the thermoelectric figure of merit declined significantly, from 0.30 of the pristine sample with a low doping of Sb (x = 0.015) at 750 K, to 0.18, and then for x = 0.06 it gradually recovered to the value of the undoped sample. The thermoelectric quality factor decreased as the Sb doping was increased, implying that Sb doping did not enhance the thermoelectric transport properties, despite the large increase in electron concentration.

A transformer is a static electric device that is used to change the alternating voltage to a higher or lower level and is used to transfer energy from one electric circuit to another without changing the frequency. When the transformer is working, there is a temperature rise in the transformer which affects the degradation of the insulating paper and transformer oil. This accelerated aging tester applies the drying and vacuuming process as well as the arrangement of paper insulation racks to achieve maximum test results. The research method refers to IEC 60216-3 2006 for aging time, IEC TS 62332-1 2014 and IEC TS 62332-1 2011 as a reference for the Development of Accelerated Aging Experimental Test Cells for Transformer Oil-immersed Paper Insulation Systems. After achieving the existing goals, the addition of the drying process resulted in quite good Breakdown Voltage test results, not only that after the addition of vacuum it produced a good oil color according to ASTM D1500 as well as after the presence of paper placement racks the results of good tensile strength testing were proven by a graph which relatively decreased from sample 1 to sample 3.

Along with technological advances in the digital era like today, which is growing faster, it has an impact on many fields. One field that has used a lot of technological developments is the CPNS Test which is based on the CAT (Computer Assisted Test) and uses many a lot of laptop/computer devices to support the implementation of the test. The many uses of computers, especially during the recruitment test, influence the quality of electrical power due to the typical character of the PC/laptop load, which is a non-linear single-phase load which results in neutral currents or currents containing harmonics. This is because the load on the pc/laptop has electronic components such as semiconductors where there is a switching process that creates an impure sinusoidal wave that causes harmonics. In the case study, the implementation of the CPNS CAT with the use of PC/laptop devices will certainly cause a fairly high THD and affect the electric current/power source. The thing that needs to be considered with a high THD and the supply of electricity from the generator is the effect on the performance of the generator and the influence of the generator’s lifetime. Briefly, the loading of the data is to reduce the derating generator set by 6,717 kVa so that the safe loading is 23.28 kVa with a maximum capacity of 30 kVa generator. Synchronous generator loading is recommended at 81% of its nominal value with a current THD of 50%.
Possível influência de Quincas Laranjeiras no desenvolvimento do estilo violonístico de Heitor Villa-Lobos
Authors: Amorim Humberto , Abreu Sérgio
Published: November 2023

Em fevereiro de 2007, ao comparar excertos de peças de Quincas Laranjeiras e Heitor Villa-Lobos até então pouco conhecidas (Dores d’Alma, Valse-Choro e Valsa Concerto N. 2), Sérgio Abreu (1948-2023) notou proximidades significativas na obra de ambos, esboçando considerar uma possível influência de Quincas na formação do “estilo violonístico” de Villa-Lobos. Em maio de 2023, no processo de organização e catalogação de seu espólio documental (Sérgio falecera em 19 de janeiro, poucos meses antes), foram encontradas seis páginas de um estudo aparentemente acabado, assinado e datado por Abreu em novembro de 2007, no qual apresenta argumentos, dados históricos e oito exemplos musicais comparativos de obras de Quincas e Villa-Lobos. Além de apresentar dados biográficos inéditos de Laranjeiras e de contextualizar o percurso de construção desse estudo, o artigo reproduz literalmente o trabalho de Sérgio, dando luz a uma de suas facetas menos conhecidas: a do músico-investigador capaz de traçar paralelos originais entre as obras de dois personagens seminais do violão no Brasil.
