Tabes dorsal y meningitis sifilítica en paciente con virus de inmunodeficiencia humana
Authors: Nassar Tobón Andrea Catalina , Rivera Rojas Neiby Johana , Mora Méndez Javier Mauricio , Gómez Suárez Andrés Mauricio
Published: December 2020

La neurosífilis es una infección causada por la bacteria Treponema pallidum, subespécie pallidum (T. pallidum). Se puede presentar en cualquier momento del curso de la sífilis, e ingresa al organismo por la primoinfección derivada de chancro primario sifilítico. La mayoría de los pacientes genera una repuesta inmunológica efectiva que evita el desarrollo de las complicaciones de la infección en el SNC, sin embargo, algunos no eliminan eficazmente tal invasión, por lo cual desarrollan neurosífilis asintomática o sintomática. La enfermedad, en cuanto a su evolución, se divide en etapas tempranas y tardías. Las primeras etapas incluyen meningitis asintomática, meningitis sintomática, goma sífilitica y sífilis meningovascular, mientras que las etapas tardías incluyen demencia paralítica y tabes dorsal. Dado que a la fecha no se cuenta con una prueba altamente específica y sensible, el diagnóstico se basa en la sospecha clínica, estudios serológicos y presencia de anormalidades del LCR. La importancia de su diagnóstico consiste en evitar complicaciones y secuelas potencialmente graves de la evolución de la enfermedad sin tratamiento. El manejo de la neurosífilis se circunscribe a recibir la terapia con penicilina. El seguimiento incluye el seguimiento de las pruebas serológicas y del LCR en pacientes específicos. Los pacientes con coinfección con VIH pueden tener un desarrollo más temprano de las características neurológicas que las personas sin la infección, así como alta probabilidad de una respuesta incompleta al tratamiento. Se presenta el caso de un hombre en la quinta década de la vida con infección por el virus de inmunodeficiencia humana (VIH) sin terapia antirretroviral, con cuadro subagudo de fiebre, compromiso de las funciones mentales superiores, pupila de Argyll Robertson, mioclonías y marcha atáxica. Las pruebas treponémicas desarrolladas en la hospitalización fueron positivas, se obtuvo un LCR anormal por la presencia de hiperproteinorraquia, así como anticuerpos antitreponemapallidum en 6,56 positivos en LCR. Se consideró el diagnóstico de tabes dorsal, por lo que se inició un tratamiento con penicilina cristalina intravenosa, 24 millones de unidades internacionales (UI)/día, durante 14 días, con evolución clínica favorable. Este artículo revisa la definición etiológica, la patogénesis, las manifestaciones clínicas, el diagnóstico y el tratamiento de la neurosífilis, con especial atención a la presencia de la neurosífilis con la coinfección con VIH y su relevancia para los clínicos en el ámbito de la neurología.
Parkinsonismo inducido por telmisartán: Reporte de caso
Authors: Fernández Yépez Luis José , Blanco Castiblanco Luis Alfredo , Fernández Fernández Elias José , Fernandez Fernández Erwin Javier
Published: December 2020

INTRODUCCIÓN:
El parkinsonismo es un síndrome clínico, caracterizado por temblor, rigidez y bradicinesia, debido a la alteración en el circuito dopaminérgico ganglio-basal, específicamente a nivel nigroestriatal. A continuación se presenta un caso de parkinsonismo inducido por telmisartán.

PRESENTACIÓN DE CASO:
Hombre de 78 años, con antecedentes de enfermedad de Parkinson de dos años de evolución, controlada con levodopa, pramipexol ER y amantadina, ingresa al servicio de urgencias por empeoramiento del parkinsonismo en las dos semanas previas a la consulta. Tenía antecedente de infarto cerebral en el territorio de la arteria cerebral posterior izquierda, hipertensión arterial crónica y diabetes mellitus tipo 2. Al examen neurológico presentaba bradicinesia y rigidez severa en las cuatro extremidades, con limitación significativa de la marcha, asociado a mioclonías. Se descartaron alteraciones infecciosas, metabólicas y lesiones agudas en la tomografía cerebral, por lo que se suspendió el telmisartán, posteriormente a lo cual los síntomas mejoraron.

DISCUSIÓN:
El parkinsonismo secundario a fármacos constituye la primera causa de este síndrome, en varios modelos farmacológicos se describe la acción que estos ejercen sobre los receptores dopaminérgicos. Así, el parkinsonismo inducido por telmisartán se considera desencadenado por disrupción dopaminérgica secundaria al antagonismo de los receptores de la angiotensina II a nivel de la sustancia gris periacueductal.
Carotid web: septo o banda carotídea: presentación de dos casos
Authors: Romero Camilo , Ujueta David
Published: December 2020

Carotid web es un término usado para describir en imágenes una anomalía vascular del desarrollo del sistema braquiocefálico. Se trata de una causa poco reconocida de accidente cerebrovascular, especialmente en pacientes jóvenes. Su frecuencia en la población general no se ha determinado y se asocia con eventos cerebrovasculares isquémicos de tipo embólico. En este reporte describimos dos casos de web carotídeo sintomático, uno que se manifiesta como un ataque isquémico transitorio (AIT) y el otro como infarto cerebral. Hasta el momento, no existe un método diagnóstico establecido como óptimo; la angiografía por resonancia magnética y por tomo-grafía se presentan como una opción confiable y alternativa a la angiografía convencional. Una vez identificado el carotid web, la evidencia es escasa con respecto a su manejo; algunas opciones con las que contamos son antiagregación, anticoagulación y manejo invasivo con endarterectomía y colocación de stent. Se dispone de poca literatura en español sobre web carotídeo. A efectos de una mejor comprensión proponemos el término de septo o banda carotídea para denominar a esta anomalía vascular.

Authors:   The Far-Eastern Institute of Management – branch of RANEPA, Barbysheva T. M.
Published: December 2020

Public-private partnership (PPP) in the conditions of the set strategic tasks by the President of the Russian Federation until 2030 can become one of the sources of attracting financial resources for implementation of the large-scale projects. In this regard, it is relevant to systematize the forms of PPPs and the scope of their application. Based on a study of different views on the essence of PPP, as well as taking into account the development of public administration in Russia, the author proposed the use of public-public-private partnership as a form of development of cooperation between the state, private business and society. The polyformism of PPPs is reflected in the presented classification. Based on the analysis of PPP development in the regional context, hypothesis on the correlation between the level of PPP and the socio-economic development of the subject of the Russian Federation was confirmed.

Limitations and transformations in the social space of coronacrisis: assessments of regions during the COVID-19 pandemic
Authors:   The Russian Presidential Academy of National Economy and Public Administration, Gordeev Sergey
Published: December 2020

The realities of the coronavirus crisis caused by the COVID-19 pandemic, in many cases, become decisive for adjusting the prospects for socio-economic development. The article presents the main results of studying the social aspect of the pandemic in the context of social heterogeneity and specific regional differences. The main points of the study are focused on analyzing the dynamics of the pandemic spreading in Russia’s regions, the specifics and effectiveness of social restrictions, and the transformation of social space. The analysis of the pandemic dynamics was carried out taking into account the information from four large industrial regions in the center of Russia and the Urals. As part of the analysis, a number of problematic issues of the social constraints effectiveness are considered, among which there are the following ones: specificity of the pandemic dynamics by regions in the context of various options for self-isolation, factors of «Path Dependence» of the social space, the consequences of redundant restrictions, social «fatigue» and «erosion» of requirements for isolation. From the viewpoint of updating the transformation priorities - spatial transformations during a pandemic, the following aspects are considered: background for moving from isolation restrictions to spatial transformations, regional employment specificity, socio-economic priorities of spatial transformation, problem-oriented zoning of a heterogeneous socio-economic space. The study is aimed at developing an adequate authorities’ and society’s response to the problems of coronacrisis, forming a regionally adapted set of measures and strategies of socio-economic transformations during the pandemic, creating a basis for solving interdisciplinary issues in the subsequent situation of «normality 2020».
Philosophy for children: an effective tool for developing independent thinking
Authors:   Institute of Philosophy of the National Academy of Sciences of Belarus, Ilyushenko Nadezhda
Published: December 2020

The content of the article is in the thematic field of practical philosophy, designated as “philosophy for children”. Within the framework of the article, the author considers specificity of the philosophical language. The main linguistic means are explicated and described, making it possible to expand the usual descriptions of the world, to achieve expression of non-trivial philosophical intuitions, to outline new directions of philosophical search. Particular attention is paid to such techniques as using metaphors, tautologies and a vicious circle in the definition in philosophical texts, as well as a step-by-step, gradual refinement of thought by introducing “operational concepts”. In conclusion, the author gives examples of tasks aimed at acquiring the language of philosophy by school-aged children (10–13 years old) as part of the program of additional education for children and adolescents “Green Sun” (team of authors: N. Ilyushenko, N. Kutuzova, D. Kutuzov, O. Davydik).

Published: December 2020

Objetivo: Averiguar a relação entre o consumo alimentar habitual de vitamina D e o peso corporal em diferentes faixas etárias de uma mesma população. Metodologia: Estudo epidemiológico transversal de base populacional, envolvendo 866 indivíduos de um município do Nordeste do Brasil. Foram coletados dados demográficos e recordatórios de 24 horas, além de avaliação antropométrica. A adequação de nutrientes foi estimada ajustando-se a variância intrapessoal da ingestão de nutrientes. Aplicou-se a regressão múltipla entre as variáveis estudadas. Resultados: Na amostra total, 45,27% dos participantes apresentavam sobrepeso ou obesidade. A média de ingestão habitual de vitamina D foi aproximadamente 2µg. Ocorreu uma relação entre o consumo alimentar habitual de vitamina D e o peso corporal na amostra total (t=-2,34; p=0,019), no grupo de adolescentes (t=-2,51; p=0,012) e de adultos (t=-2,75; p=0,006). Para as crianças e os idosos estas relações não foram observadas. Conclusão: A existência de uma relação entre o consumo alimentar habitual de vitamina D e o peso corporal em adolescentes e adultos, no entanto, não foi observada em crianças e idosos, sugerindo que nesses grupos etários, mais vulneráveis, as vias metabólicas da vitamina D que, provavelmente, favorecem a perda de peso, não estão sendo estimuladas ou atuantes, embora, o consumo das crianças tenha sido superior e o dos idosos semelhante aos demais grupos.
Carcinoma [ID 53101] CARCINOMA DUCTAL INVASIVO OU IN SITU: EXISTEM DIFERENÇAS DE ACORDO COM O PERFIL DAS PACIENTES?
Authors: De Melo Souza Felipe , Apolinário da Silva Leandro , Da Silva Solange Maria , Morais de Sousa Kleber , Vitalino de Almeida Sinara Mônica
Published: December 2020

Objetivo: Caracterizar e investigar diferenças nos pacientes com carcinoma ductal de mama segundo o diagnóstico in situ (CDIS) ou do tipo invasivo (CDI). Metodologia: Análise descritiva e exploratória de população atendida em setor de oncologia entre 2010 a 2018, a partir da distribuição comparativa para os grupos CDIS e CDI segundo variáveis relacionadas ao perfil sociodemográfico, aos fatores de risco reprodutivos e comportamentais, além dos tratamentos utilizados. Resultados: Os resultados obtidos para a amostra formada por 119 pacientes, 47,06% do tipo CDIS e 52,94% CDI, indicaram que ambos os grupos apresentaram maior frequência de surgimento da doença ≥ 50 anos de idade. Os fatores reprodutores foram diferentes no perfil in situ, provavelmente devido ao efeito protetor do número de partos e menarca na faixa etária entre 12 e 15 anos de idade. A maioria das pacientes apresentou positividade para receptores hormonais, evidenciando um perfil menos agressivo. O tratamento quimioterápico foi a principal abordagem terapêutica para ambos os grupos, com destaque para o grupo CDI. Conclusão: Os grupos CDI e CDIS apresentaram diferenças para os fatores reprodutores, enquanto as variáveis idade e positividade para os receptores hormonais não mostraram diferenças, o que pode justificar a adoção do mesmo esquema terapêutico. Existe, portanto, a necessidade de aprofundar a investigação sobre outros fatores que possam diferenciar as formas in situ e invasiva do câncer de mama.

Authors: Paulino Portela Ana Rebeca , Rolim de Holanda Viviane , Pereira Melo de Albuquerque Geyslane
Published: December 2020

Objetivo: Conhecer a percepção de usuárias do Sistema Único de Saúde brasileiro sobre o plano de parto. Metodologia: Trata-se de uma pesquisa qualitativa de caráter exploratório e descritivo. Foram entrevistadas puérperas, que realizaram o pré-natal e o parto no serviço público de saúde, na Cidade de Vitória de Santo Antão, Pernambuco, Brasil. Utilizou-se o critério de saturação teórica para dimensionar a amostra e verificar, objetivamente, o esgotamento do conteúdo para análise. Os resultados obtidos nas entrevistas foram analisados segundo a técnica de análise de conteúdo temática proposta por Bardin. Resultados: Emergiram três categorias de análise: percepção sobre o plano de parto; o impacto do plano de parto na maternidade; vivências do parto. O incentivo à construção do plano de parto ainda é deficiente nas consultas individuais de pré-natal, no entanto, nos espaços coletivos de rodas de gestantes, diante da atuação multiprofissional, a sua divulgação vem se fortalecendo. Quanto à assistência hospitalar, foi possível perceber, nas falas das mulheres, a resistência dos profissionais em legitimar o plano de parto. Conclusões: Percebeu-se, nas falas das usuárias, o plano de parto como instrumento essencial para a construção de suas experiências na gestação e no momento do parto. As vivências relativas ao parto foram percebidas como satisfatórias, mesmo o plano de parto não sendo reconhecido pela equipe de profissionais, como um instrumento legal e de direito da gestante. Por outro lado, identificou-se, a partir dos discursos relativos ao momento do parto, a prática de intervenções não baseadas nas evidências científicas.
The impact of internal governance mechanisms on financial and stock market performance of listed companies: Evidence from an emerging market
Authors: Berbou Houcine , Sadqi Oumaima
Published: December 2020

The aim of this paper is to empirically test the impact of internal governance mechanisms on the financial and stock market performance of Moroccan listed companies. Board of directors’ characteristics such as independence and transparency, concentration, and presence of employees in the ownership structure, as well as some cognitive aspects of governance, represent the basis for discussion. Secondary data of a sample of 44 listed companies in the Casablanca Stock Exchange was analyzed using multiple linear regression. The results of this empirical study revealed that the financial and stock market performance of the companies that are captured by the return on equity (ROE) and the market to book ratio (M to B) significantly correlate with the adoption of the hybrid corporate governance approach. The relevance of this study is to enrich researches that deal with corporate governance and its impact on business performance in the context of Moroccan listed companies.

Published: December 2020

Anomalous Aortic Origin of Coronary Artery (AAOCA) is a rare finding,
with varied presentation and symptomatology. Increasingly recognized by
cardiac imaging, when found it raises questions about the appropriate
approach and management. We present a case of an 11-year-old female who
presented with episodes of shortness of breath, angina and syncope
during exercise. Further investigation demonstrated episodes of
nonsustained ventricular tachycardia on Holter and coronary
angiotomography revealed that the left coronary artery had an anomalous
origin from the right cusp with initial short intramural segment and
significant external compression in its initial course between the aorta
and the pulmonary artery. Patient was submitted to surgical correction
with dissection of left coronary artery posterior to the pulmonary
artery, coronary arteriotomy, roof ampliation with autologous
pericardium and creation of neo-ostium in aorta. Patient had
satisfactory postoperative recovery, was discharged on the fifth day
post op, and remains asymptomatic after six months follow-up. Herein we
present surgical video and postoperative echo and CT scan.
DrCaptcha: An interactive machine learning application
Authors: Glikis Rafael , Makris Christos , Tsirakis Nikos
Published: December 2020

The creation of a Machine Learning system is a typical process that is mostly automated. However, we may address some problems in the during development, such as the over-training on the training set. A technique for eliminating this phenomenon is the assembling of ensembles of models that cooperate to make predictions. Another problem that almost always occurs is the necessity of the human factor in the data preparation process. In this paper, we present DrCaptcha [15], an interactive machine learning system that provides third-party applications with a CAPTCHA service and, at the same time, uses the user's input to train artificial neural networks that can be combined to create a powerful OCR system. A different way to tackle this problem is to use transfer learning, as we did in one of our experiments [33], to retrain models trained on massive datasets and retrain them in a smaller dataset.
Protected areas management in public enterprise "Vojvodinasume": Sources and areas of subsidies use
Authors: Vasic Ivana , Rankovic Nenad , Nedeljkovic Jelena , Nonic Dragan
Published: December 2020

One of the most complex issues in a protected area (PA) management is the
provision of adequate financial resources. Managers of PAs in Serbia are
financed from several different sources: budget through the allocation of
subsidies, fees for the PAs use, revenues generated through the business
operating and management, funds provided for project implementation,
donations, gifts, aids, etc. Public enterprise (PE) "Vojvodinasume" is the
manager of 16 and the user of 19 PAs in the territory of Vojvodina. In this
paper, two research goals are defined. The first goal refers to the
determination of a statistically significant difference in the sources of
subsidies according to the selected PAs, and those are special nature
reserves: ?Obedska bara?, ?Koviljsko-petrovaradinski rit?, ?Bagremara?,
?Gornje Podunavlje? and ?Deliblatska pescara?. The second goal is the
determination of a statistically significant difference in the areas of
subsidising, related to the selected PAs. In this paper, PE ?Vojvodinasume?
internal data for the period 2009-2019 were used. The research has
determined funds provided by the national and provincial budgets as the most
important sources of subsidies for the observed PAs. Concerning the areas of
subsidising, most of the funds were allocated for the monitoring and
improvement of the PAs conditions, which determined PE ?Vojvodinasume? for
taking an active approach to nature conservation.

Authors: Malisic Vanja , Tomic Natasa , Vuksanovic Marija , Balanc Bojana , Stevic Zoran , Marinkovic Aleksandar , Jancic-Heinemann Radmila , Putic Slavisa
Published: December 2020

Thermal properties of acrylate-based composite combined with alumina-based
particles were investigated. The composites were made of poly (methyl
methacrylate) (PMMA) modified with dimethyl itaconate (DMI) as a matrix.
Neat alumina particles (Al2O3) and alumina doped with iron oxide (Al2O3-Fe)
modified with 3-aminopropyl-trimethoxylane (AM) and flax oil fatty acid
methyl esters (biodiesel - BD) were used as reinforcement. Thermal
conductivity measurements showed that composite with alumina particles with
the highest alpha phase content had the highest thermal conductivity values.
Mechanical properties (tensile strength, modulus of elasticity and
elongation at break) were improved by the addition of modified alumina
particles to PMMA/DMI matrix. The thermal properties are the most improved
for composite with 3 wt.% Al2O3-Fe-AM particles that had the lowest
temperature in a crack zone was noticed (10.28 %) compared to PMMA added due
to the better stiffness and highest thermal conductivity.
Local provenance of raw materials for prehistoric pottery production at the Spasovine tin placer site (Western Serbia)
Authors: Powell Wayne , Pacifico Lina , Mitchell Terrence , Cruse Steffanie , Bankoff Arthur
Published: December 2020

Archaeological finds at Spasovine, on the south flank of Mt Cer, near the
town of Milina, indicate that it was settled in the Eneolithic and
seasonally inhabited for tin placer mining in the Late Bronze Age. The site
is highly disturbed and abraded domestic pottery is the most common material
found. An analysis of the mineralogical assemblages that comprise the temper
sand in a subset of the prehistoric pottery sherds from the site indicate
that the sand was obtained from the adjacent Milinska River. Key minerals
that link the pottery to on-site production from local materials include
almandine-spessartine series garnets, the tin-bearing mineral cassiterite
(SnO2) and a microlite group mineral ([Ca,Sn,U]2[Ta,Nb]2O6(OH,F]). The
unusually common occurrence of cassiterite within the pottery sherds
relative to the abundance in the Milinska today suggests that the tin ore
grade in the Milinska River may have been significantly higher in
prehistory.
Revisiting “Tin in South-eastern Europe?”
Authors: Powell Wayne , Mladenovic Ognjen , Cruse Steffanie , Bankoff Arthur , Mathur Ryan
Published: December 2020

The important role of the Balkans in the origin and development of metallurgy
is well established with respect to copper. In addition, Aleksandar Durman,
in his 1997 paper ?Tin in South-eastern Europe??, essentially initiated
studies into the role of the Balkans in Europe?s Bronze Age tin economy. He
identified six geologically favourable sites for tin mineralisation and
associated fluvial placer deposits in the former Yugoslavian republics, and
suggested that these may have added to the tin supply of the region. The
viability of two of these sites has been confirmed (Mt Cer and Bukulja,
Serbia) but the exploitation potential for the other locations has remained
untested. River gravels from these four sites (Motajica and Prosara in
Bosnia and Herzegovina; Bujanovac in Serbia; Ograzden in North Macedonia)
were obtained by stream sluicing and panning. The sites of Prosara and
Bujanovac were found to be barren with respect to cassiterite (SnO2).
Streams flowing from Motajica and Ograzden were both found to contain
cassiterite, but in amounts several orders of magnitude less than at Mt Cer
and Bukulja. Although it is possible that minor tin recovery occurred at
Motajica and Ograzden, it is unlikely that they could have contributed
meaningfully to regional tin trade. This is supported by the fact that the
isotopic signature (?124Sn) of cassiterite from Motajica is highly enriched
in light isotopes of tin compared to that associated with Late Bronze Age
artefacts of the region.
Monumental altar from Singidunum with scenes of a sacrificial procession - pompa et immolatio
Authors: Gavrilovic-Vitas Nadezda
Published: December 2020

A monumental altar was found in the very centre of Belgrade, ancient
Singidunum, in 1932, with iconographic scenes of the sacrificial procession
for a ritual animal sacrifice - immolatio. The scenes depict the procession
of sacrificial animals to the altar known as pompa, by the victimarii, but
also represent priests of a lower rank (flamines minores), with ritual
utensils like a wine-pitcher, patera and acerra, used for the ritus of
purification which precedes the sacrifice and for ritual acts during the
sacrifice. The altar from Singidunum represents a unique monument with the
described iconography in the territory of Moesia Superior and it has only

Block-type military balneum in Timacum Minus its spatial arrangement, social impacts, and architectural analogies
Authors: Bjelic Igor
Published: December 2020

The remains of a Roman bath are situated northeast of the remains of the
Timacum Minus castrum. The discovered building is small in size, with a
total area of about 242 m?. According to the specific layout of rooms, with
a reduced spatial organization of its plan, the building belongs to the
reduced block-type of military small baths - balneae. In the territory of
Serbia, no military balneae of this type have been discovered so far, which
are otherwise common for border areas throughout the Roman Empire. The
specific spatial relationship between the individual rooms and the
characteristic building forms registered in the building plan indicate that
the origin of the architecture of the military balneum in Timacum Minus
should be associated with the Roman architecture of the balneae that belong
to the villae rusticae in Central Europe.

Published: December 2020

In this paper, efforts have been taken to generalise the notion of anti-fuzzy subgroup. Proposed definition was supported by graphical comparison with our previous result and suitably constructed examples. Based on the introduced definition, we derive not only some results of anti-fuzzy subgroup but also we redefine lower level set and lower level subgroup, and derive some essential theorems to study some algebraic characteristics. Further, a modified notion of lower level subgroup is given.

Oscillating laser hot-wire tungsten inert gas (TIG) hybrid welding of 10 mm thick 316LN austenitic stainless steel in the vertical position was performed. The characteristics of droplet transfer, molten pool formation, and forming mechanism of different oscillating parameters were investigated by the experimental method. A high-speed camera was employed to observe the arc, droplet transfer, and molten pool formation. Results showed that the larger molten pool area, more intense fluid flow, and better weld bead formation were achieved when the oscillating laser joined to TIG as compared to TIG or normal laser-TIG hybrid welding. Due to the dynamic wire feed, the form of droplet transfer was mainly contact transfer, and the frequency of droplet transfer was equal to the frequency of wire feed and was independent of the parameters of the heat source. The electrical signals in the TIG and oscillating laser-TIG weld processes were collected, respectively, and the results showed that the change of conductivity might be the reason why the laser can compress the arc. The addition of laser increased the arc voltage and active power and improved the efficiency of hybrid welding.
Análisis del consumo hedonista del reguetón en mujeres millennials del estado de Jalisco, México
Authors: Machaen López Luz Elena , Carrillo Torres Paulo Alberto , Quiroz García Elisander
Published: December 2020

El género musical reguetón de origen latino, es un híbrido compuesto por diversos géneros y ritmos populares, que ha sido criticado desde sus inicios por ser precursor de la violencia, detonante de actos criminales, portador de contenido sexual explicito e implícito, misógino y promotor del perreo (baile en el que se explota sexualmente a la mujer a través de movimientos eróticos y soeces de manera semidesnuda). Además ha sido considerado artísticamente deficiente, como una representación muy elemental de expresión musical. Aun así, hoy en día ha alcanzado un éxito comercial mundial, escuchado por hombres y mujeres de todas las edades lo cual ha provocado que intérpretes de otros géneros incursionen en él con excelentes resultados. Considerando estas observaciones, en el presente estudio se planteó la siguiente interrogante: ¿cuáles son las razones que motivan a mujeres de la generación millennials (es decir, aquellas nacidas entre 1981 y 1997), a consumir por placer este tipo de música?

            Para intentar ofrecer una respuesta se construyó una encuesta semiestructurada en la cual se emplearon técnicas proyectivas, así como la reproducción del audio y la lectura de letra de la canción. La selección de las mujeres se concretó mediante un muestreo en cadena o bola de nieve. En total participaron seis universitarias del estado de Jalisco (México).

Los resultados evidencian que las millennials escuchan el género debido a que les provoca activación y energía para realizar sus actividades cotidianas, así como alegría, diversión y bienestar. El género, en otras palabras, logra cambiar su estado anímico de tristeza o ansiedad por relajación y felicidad. También se encontró que no prestan demasiada atención a las letras de las canciones y que el ritmo es lo que las estimula a consumirlo, salvo en aquellas ocasiones donde las letras son altamente denigrantes o pervertidas.

Published: December 2020

This article figures out ideological biases in AbÅ« Rashtah Bookâ€™s, al-TaysÄ«r fÄ« 'UlÅ«m al-TafsÄ«r: Tafsir al-Baqarah. As a figure of á¸¥izb al-taá¸¥rÄ«r, AbÅ« Rashtah's interpretation strengthens his organization's ideology and to oppose the ulama's interpretation. This article questions how the al-TaysÄ«r methodology was used by AbÅ« Rashtah for interpreting al-Qur'an and how the biases of AbÅ« Rashtah's interpretation in his book. By using thematic writing techniques on khilÄfah verses and using descriptive analysis methods, This research concludes that the method of interpretation applied in his book prioritizes linguistic analysis and the use of reason. Through this method of language based on reason, it was found that there were ideological biases. One of them is the persuasion of the enforcement of the khilÄfah Islamiyyah system when he interprets the QS. Al-Baqarah: 30. AbÅ« Rashtah is of the view that this verse is the normative basis for the enforcement of the khilÄfah system. Apart from the above verse, the invitation to enforce the khilÄfah system can also be found in the QS interpretation of al-Baqarah: 105. AbÅ« Rashtah believes that the KhilÄfah Islamiyyah will soon be established on the face of the earth according to Allah's promise.
Tafsir Pendidikan Perempuan Menurut Qasim Amin
Authors: Munfarida Elya
Published: December 2020

The encounter between Arab Islam and colonialism and modernity resulted in a revival of Arab Islamic intellectuals with an orientation to reinterpret the Islamic tradition. Qasim Amin as one of the Nahdah figures tries to reinterpret Islamic teachings and traditions, especially those related to women, by accommodating modern ideas and culture. Based on his criticism of the reality of the restriction and subordination of women in the public sphere, Amin tries to reinterpret women's education in Egypt by re-exploring the texts of the Koran and hadiths that talk about women's rights and obligations, the interpretations of the scholars of the two texts, the values â€‹â€‹and basic principles of Islamic shari'ah that underlie Islamic legislation, as well as sociological theories and liberal feminist thinking. According to Amin, women's education is very significant with three interests, namely society in the form of participation in various fields in the public sphere, the family in the form of the ability to be able to better protect their children, and the state in the form of producing offspring with good intellectual and moral qualities that have an impact on the progress of the country. The realm of education that must be accessed by women includes intellectual, moral, and physical education.
