The Urgency of a Legal Protection on Equity Crowdfunding Services Based on the Regulation of the Indonesian Financial Service Authority No. 57/POJK.04/2020
Authors: Yuspin Wardah , Rohmah Wati Nur
Published: February 2022

A crowdfunding service that is carried out through information technology-based stocks or commonly known as equity crowdfunding is an innovation in the development of the digital economy. It is a supporting factor of Indonesia’s economic development as stipulated in the Regulation of the Financial Service Authority (RFSA) No. 37/POJK.04/2018. In 2020, this regulation was perfected into RFSA No. 57/POJK.04/2020 concerning the crowdfunding activity expansion, starting from the issuer to the stock. In RFSA No.57/POJK.04/2020 there was a transitional provision that became a problem for equity crowdfunding service program organizers in expanding their business according to RFSA No.57/POJK.04/2020. It concerns the grace period and the revocation of the permit by the Financial Service Authority if the organizers fail to reregistered during the determined grace period, though in expanding the business activity, there needs to be a profound analysis to prevent users from experiencing loss. This limited grace period certainly brings loss to the organizers, thus there needs to be a solution to keep the crowdfunding services running. Because of that, this research analyses the transitional provision in the RFSA No.57/POJK.04/2020 concerning equity crowdfunding in Indonesia. This paper uses the normative approach with a literature review analysis. The results are presented qualitatively. Research results show that there needs to be an additional grace period in the transitional provisions so organizers have enough time to undergo analyses in expanding their business activities. This is to prevent organizers or users from experiencing losses in the future.

Authors: Radi Meybodi Fatemeh , Rasouli Saeedeh
Published: February 2022

Following the ratification of the Universal Declaration of Human Rights, Islamic countries also decided to adopt the Universal Declaration of Human Rights based on Islamic teachings. In this way, a declaration in accordance with Islamic principles is available to Islamic countries and the differences caused by the religion of Islam are considered, respected and acted upon. Different issues have been emphasized in both declarations, including women and the family. Therefore, the present study is a comparison between two declarations in the field of women and family issues. The method of collecting information is in the form of libraries and the method of processing them is descriptive-comparative. We see significant differences and similarities in both declarations on women and the family. Among the differences are the issues of paying alimony, raising children and equality between men and women.

La Calle, un Territorio con otras prácticas, otros saberes y otros sentidos
Authors: Forero Hurtado Andrea , Torres Poveda Andrés
Published: February 2022

Tras una intervención de la alcaldía de Bogotá en 2016 a una zona del centro de la ciudad, deprimida por fenómenos de narcotráfico, prostitución, miseria e ilegalidad, conocida como El Bronx o La Ele, se desarrollaron acciones para la atención de las personas que ocupaban el sector; algunas centradas en el arte, como la obra de teatro musical “Gloria, un canto a la vida”. De allí la investigación “Del territorio de la calle al territorio de la escena teatral”. La riqueza de los relatos sobre las prácticas y los saberes de La Calle como territorio, es decir como espacio de la construcción de sentidos, dieron pie a este artículo. El tema principal en este escrito, antes que el hecho teatral, es el fenómeno de habitabilidad de calle descubierto a través de las narrativas y que suscitaron reflexiones y tímidas propuestas de manejo.

Diseño de experiencias aplicado al interiorismo comercial en la Ciudad Autónoma de Buenos Aires. Casos de estudio: Herencia Custom Garage y Blackmamba
Authors: García Romero Paola
Published: February 2022

El Diseño de Interiores relacionado a espacios comerciales constituye una rama del diseño en potencial crecimiento que con los años se ha visto influenciada principalmente por el cambio constante de las demandas del mercado. Respecto a estos cambios, Zorrilla (2002) señala que hay que tener en cuenta que las estrategias de marketing tradicional ya no tienen el mismo éxito de antes y que los clientes están cada vez mejor informados, son más selectivos y están en búsqueda no sólo de opciones más económicas sino también más rápidas. Por otra parte, Schmitt (1999) sostiene que dedicarse solamente a diseñar productos o servicios, ya no es suficiente.

¿Qué es lo más bello y adecuado? ¿Una cuchara de oro o de madera de higuera? […] ¿No es evidente que la de madera de higuera? Da más aroma a la legumbre y, además, no podría romper la marmita ni derramaría la verdura, ni apagaría el fuego, dejando sin un plato muy agradable a los que iban a comer. En cambio, la de oro podría hacer todas estas cosas, de manera que, según parece, podemos decir que la de madera de higuera es más adecuada que la de oro, a no ser que tú digas otra cosa.

Moda, clase social y habitus
Authors: Jiménez Gómez Joan
Published: February 2022

El debate sobre la ineficacia del concepto de clase como categoría de análisis sociológico, mencionado en los escritos de Ray E. Pahl en Divisiones del Trabajo y de Jan Pakulski y Malcom Waters The Death of Class; contribuyeron a acrecentar las críticas profundizando de forma negativa la teoría de la distinción de Bourdieu (2010), aludiendo a que se fundamenta en una relación entre clase, formación del gusto y consumo, superada por la fragmentación social y la globalización. En este sentido destacamos Coulangeon and Lemel en Social Status and Cultural Consumption del año 2010. Este escrito contrapone que, aunque en sociedades sumamente desarrolladas y democráticas, se observan consumos individualizados y omnivoristas, éstos se desarrollan a partir de diferenciaciones simbólicas, grupos de referencia, ocupaciones y niveles de renta. Por lo que la pertenencia a una clase social resultará un factor clave para la compra de moda. Sin embargo, respecto al habitus, que sea sobreestimado como un inconsciente de clase, aun siendo una estructura estructurante, induce a pensar que las prácticas de consumo son poco inteligibles. De ahí la relevancia de considerarlo como conciencia de clase.
El manierismo en la moda. Saturación y agotamiento del gusto
Authors: Fernández Diana
Published: February 2022

El carácter efímero de la moda constituye un elemento consustancial de su existencia. Es esa fugacidad arbitraria lo que la singulariza y marca la principal diferencia con otros comportamientos del ser humano. El manierismo como tendencia al rebuscamiento expresivo y gusto por la acentuación de determinadas características artísticas hasta que resultan afectadas, servirá de hilo conductor del presente texto, revelando su presencia en la moda como expresión del carácter autodestructivo de la moda y su reflejo en la exageración de estilos que anuncian el tránsito a uno nuevo, algo que se evidencia en varios momentos de la historia del vestir.
Desde el discurso médico: perspectivas sobre las disfunciones sexuales femeninas y masculinas en el Perú contemporáneo
Authors: Olivera Skarlet , Ramos Rosario , Herrera Alejandra
Published: February 2022

En sociedades históricamente heteropatriarcales como el Perú, el tema de la sexualidad se enmarca en un contexto de mitos, tabúes y desinformación, el cual es, en parte, construido por procesos de medicalización. Dentro de ello, las disfunciones sexuales son concebidas como trastornos o patologías que requieren ser diagnosticados y tratados por personal especializado. De este modo, la presente investigación se propone explicar las formas en que las disfunciones sexuales, tanto femeninas como masculinas, son abordadas actualmente desde el discurso médico. A través de una metodología eminentemente cualitativa que tiene como muestra a profesionales del campo de la salud, los principales hallazgos van referidos a las causas de las disfunciones sexuales y al enfoque de género presente en todo el proceso de diagnóstico, tratamiento y percepción. Como causa, el factor social juega un rol importante pero siempre circunscrito en lo que se considera psicológico o psicosomático. Asimismo, el aspecto generacional y de género en las personas entrevistadas es fundamental para explicar diferencias en torno a sus perspectivas médicas y heteronormativas. Finalmente, se concluye que, la percepción sobre disfunción sexual se ve afectada por construcciones de feminidades y masculinidades propias de sistemas hetero-cis-patriarcales.
Huertos universitarios y necesidades humanas: una aproximación bibliográfica y vivencial desde el huerto agroecológico de la Universidad Veracruzana en México
Authors: Fontalvo Buelvas Juan Camilo , De la Cruz Elizondo Yadeneyro
Published: February 2022

Los huertos universitarios son espacios de pequeña extensión, que han sido conformados en primera instancia con fines educativos y productivos; sin embargo, estas áreas verdes citadinas ofrecen mucho más que aprendizajes y alimentos. Desde la perspectiva del desarrollo humano, estos espacios cultivados podrían ser un canal para satisfacer de forma simultánea necesidades humanas fundamentales. Por tanto, el objetivo de este estudio es explicar la relación entre los huertos universitarios y la satisfacción de necesidades humanas fundamentales a través de una aproximación bibliográfica y vivencial desde el Huerto Agroecológico de la Facultad de Biología de la Universidad Veracruzana en México. Esta investigación exploratoria se realizó siguiendo la metodología de estudio de caso, la cual distingue cuatro etapas: formulación de la pregunta de reflexión, unidad de análisis, métodos e instrumentos de recolección de la información y análisis de la información. Los resultados mostraron que el huerto universitario puede responder primordialmente a la satisfacción de las necesidades de ocio, entendimiento, participación e identidad, y, en menor medida, a las necesidades de subsistencia, protección, creación, libertad y afecto. Algunos beneficios asociados a la satisfacción de necesidades en estos espacios cultivados están relacionados con la sustentabilidad urbana y el bienestar social, aspectos fundamentales que promueve la agroecología urbana. Las conjeturas aquí descritas pueden representar un punto de partida importante para una discusión más profunda sobre la relación existente entre los huertos y las necesidades humanas. En un siguiente momento será necesario visualizar aquellas herramientas metodológicas que permitan describir los procesos y fenómenos sociales aquí suscitados.
Un análisis econométrico sobre la influencia de la apertura comercial, capital humano, inversión y trabajo en la desigualdad en el Perú (1997-2019)
Authors: De la Cruz Flores Martha Sofía , Camino Escudero Mayra M.
Published: February 2022

El objetivo de este artículo se centra en analizar el impacto de la apertura comercial, el capital humano, el crédito privado y variables relacionados al trabajo y la especialización en la desigualdad de ingresos en el Perú durante el período de 1997 a 2019. Se emplea un modelo de regresión lineal múltiple basado en la metodología de mínimos cuadrados múltiples (MCO), usando datos de series de tiempo que matematizan la relación entre estas variables y la desigualdad de ingresos, que toma en consideración la especialización de la oferta laboral. Se comprobó la relación entre las variables independientes: capital humano y la apertura comercial, y la variable dependiente, el Gini, midiendo la desigualdad en el modelo final. Es importante mencionar que se han considerado los efectos de hechos históricos que afectaron al mercado en 2007, 2011 y 2019. El debate acerca del verdadero impacto de la apertura económica en la desigualdad de ingresos ha estado presente a lo largo de la historia. Por ello, la pertinencia de este trabajo radica en encontrar explicaciones prácticas en un escenario de profunda inestabilidad política y económica. Se busca hallar una de las causas de la desigualdad de ingresos que viene acompañando al Perú desde hace décadas. Dado que no se ha visto una reducción significativa, se requiere demostrar qué tipo de efecto tiene la globalización –durante las últimas dos décadas– en la lucha contra la desigualdad de ingresos en la sociedad peruana. Los resultados obtenidos demuestran que, en este caso, la apertura comercial sí tiene un impacto positivo en la reducción de la desigualdad de ingresos. Así mismo, se encuentran resultados inconclusos respecto de la naturaleza de la especialización y capacitación del capital humano en un entorno de apertura económica. En estos, se observan comportamientos contradictorios con la teoría económica y los estudios empíricos.
Using unfair means in undergraduate E-learning programmes in English: an analytical survey
Authors: Alkhaza'leh Bilal Ayed , Kumar Tribhuwan , Kumar Tribhuwan
Published: February 2022

This study aims to emphasize students’ views on using unfair means in e-learning programmes in English at undergraduate level. The research examines further how they trick, why they trick, and possible approaches to decrease this unfair practice. This investigation was carried out after the second half of 2020 when the whole world was witnessing the impact of COVID. Data from 60 students of undergraduate programmes in English offered different Indian universities in correspondence mode have been obtained. This study utilized a mixed-method research strategy by use of a tailor-made, fourteen closed-ended and one open-ended item questionnaire. Frequency and percentage analysis was performed in the quantitative portion and open questions were thematically analyzed. The data show that the majority of students cheated on others by receiving the right answers from or sending the right answers to their peers. Another technique, as claimed by some of them, being employed was copying answers from electronic website susing the internet resources and then pasting them onto the screen of the exam portal. The survey further indicated that grounds for fraudulent e-learning programmes, often without virtual classrooms, were not always attributable to technical difficulties and to students who wished to graduate and gain knowledge.

South Asia, a home of 1.7 billion people houses the most poor and malnourished people globally. The region need to double its food production by 2050. Current scenario puts South Asian agriculture in a dilema facing triple challenges: to increase production to meet the food demand of growing human population with a lower environmental footprint, preserve natural resources and mitigate or adapt to the changing climatic scenarios. Conservation Agriculture offers a number of benefits such as arresting and reversing the resource degradation, decreasing cultivation costs, making agriculture more resource – use-efficient, competitive and sustainable whilst increasing resilience to climatic variability and improving livelihood incomes in South Asia. The CA approach for managing agro-ecosystems is of paramount significance in improving soil health, sustained productivity and maintaining natural biodiversity. However, there is still a large knowledge gap in understanding of nutrient and water management in CA systems.

Published: February 2022

O acesso à água é essencial a manutenção da vida dos seres humanos, entretanto mesmo sendo indispensável, a própria atividade antrópica a torna poluída. Faz-se necessário o desenvolvimento de técnicas alternativas que sejam eficientes na remoção de poluentes, de fácil implementação e possuam viabilidade econômica, dentre tais alternativas o processo de adsorção apresenta-se como uma boa solução. A adsorção consiste na separação de uma fase fluida denominada adsorvato, por meio de uma fase sólida porosa denominada adsorvente, que possui características para aderir uma das espécies que estavam contidas na fase fluida inicialmente, tal capacidade dos adsorventes varia dependendo das características dos materiais, da extensão das alterações químicas, e da concentração de adsorvato. Os compostos farmacêuticos são substâncias amplamente presentes na sociedade moderna, produzidos para atingirem rotas metabólicas de seres humanos e animais, causam por consequência efeitos colaterais, tais produtos estão sendo encontrados no ambiente em níveis que variam de ng L-1 a µg L-1, assim sendo conhecidos como contaminantes emergentes. O objetivo deste artigo foi analisar os trabalhos realizados dos últimos dez anos presentes nas principais bases de dados, para a obtenção de um levantamento qualitativo dos materiais publicados. Para tal, foram realizadas pesquisas quanto a utilização de diferentes adsorventes para a remoção de compostos farmacêuticos da água. Além disso, também foram verificados os melhores materiais e condições para execução deste método de tratamento.

O objetivo deste trabalho foi produzir e caracterizar extratos aquosos e concentrados de fibras alimentares obtidos a partir do subproduto da goiaba, utilizando diferentes condições de processo. Após a remoção da polpa, as cascas foram submetidas a secagem e moagem. Este material passou por diferentes tipos de tratamentos em shaker (SH), ultrassom (US), micro-ondas (MO), banho-Maria (BM) e homogeneizador (HO). Após centrifugação, os extratos foram avaliados quanto ao teor de compostos fenólicos totais (CFT) e atividade antioxidante (AA). Os precipitados foram secos, triturados, peneirados, sendo denominados concentrados fibrosos (CFs), os quais foram analisados quanto à composição e propriedades funcionais. Os resultados mostraram que os extratos obtidos em MO e US apresentaram o maior teor de CFT e AA, respectivamente, e que após estes tratamentos, os CFs produzidos continham os maiores teores de proteínas (9.71 g.100 g-1; 10.78 g.100 g-1) e de fibras alimentares (60.44 g.100 g-1; 65.63 g.100 g-1). Os tratamentos realizados permitiram reduzir o teor de açúcares redutores totais e aumentar o índice de absorção de água dos CFs quando comparado ao controle (sem extração aquosa). Assim, a obtenção de compostos antioxidantes e concentrados fibrosos são consideradas alternativas interessantes para valorizar a cadeia produtiva da goiaba, fornecendo destinos mais sustentáveis ao subproduto gerado no processamento industrial desta fruta, como uma fonte de nutrientes para enriquecimento de produtos alimentícios ou para ser utilizado como suplementos.
Grapevine rootstock genotypes influences berry and wine phenolic composition (Vitis vinifera  L. cv. Pinot noir)
Authors: Blank Magali , Samer Sabrina , Stoll Manfred
Published: February 2022

Grapevine rootstocks can affect the nitrogen (N) status of the grafted plant due to discrepancies in their nutrient uptake and their efficiency in the allocation of assimilates. When N becomes a limiting factor, the production of phenolic compounds in grapes is enhanced as a result of a down-regulation of the flavonoid production pathway. However, it is still not fully understood if the impact of rootstocks on fruit and wine composition is mediated by their effect on the vegetative growth and N status of the scion. The main objective of the study was to test if rootstock influence on Pinot noir berry and wine phenolic composition could be related to the N status of the scion. An investigation was carried out on Pinot noir (Vitis vinifera L.) vines grafted onto six rootstocks over three vintages (2012–2014). A micro-scale fermentation technique was used to produce wines from each field replicate. Scions grafted onto SO4, a high vigour rootstock, were characterised by a 15 % higher tannin concentration in berry seed and skin compared to those grafted onto the low vigour Riparia Gloire de Montpellier, while final tannin concentration in wines depended on the rootstock. Anthocyanin concentration was higher in berries of Pinot noir grafted onto R110 compared to 125AA, which was also reflected in the wines. A Multiple Linear Regression analysis suggested that rootstock influence on berry anthocyanins was linked to the N status of scion leaves (higher Leaf NBI_R). Understanding the interaction between the N uptake efficiency of rootstocks and scion berry/wine phenolic composition will help improve the selection of suitable rootstocks that match the desired wine profile.
Reduced Numerical Modeling of Turbulent Flow with Fully Resolved Time Advancement. Part 1. Theory and Physical Interpretation
Authors: Kerstein Alan R
Published: February 2022

A multiscale modeling concept for numerical simulation of multiphysics turbulent flow utilizing map-based advection is described. The approach is outlined with emphasis on its theoretical foundations and physical interpretations in order to establish the context for subsequent presentation of the associated numerical algorithms and the results of validation studies. The model formulation is a synthesis of existing methods, modified and extended in order to obtain a qualitatively new capability. The salient feature of the approach is that time advancement of the flow is fully resolved both spatially and temporally, albeit with modeled advancement processes restricted to one spatial dimension. This one-dimensional advancement is the basis of a bottom-up modeling approach in which three-dimensional space is discretized into under-resolved mesh cells, each of which contains an instantiation of the modeled one-dimensional advancement. Filtering is done only to provide inputs to a pressure correction that enforces continuity and to obtain mesh-scale-filtered outputs if desired. The one-dimensional advancement, the pressure correction, and coupling of one-dimensional instantiations using a Lagrangian implementation of mesh-resolved volume fluxes is sufficient to advance the three-dimensional flow without time advancing coarse-grained equations, a feature that motivates the designation of the approach as autonomous microscale evolution (AME). In this sense, the one-dimensional treatment is not a closure because there are no unclosed terms to evaluate. However, the approach is additionally suitable for use as a subgrid-scale closure of existing large-eddy-simulation methods. The potential capabilities and limitations of both of these implementations of the approach are assessed conceptually and with reference to demonstrated capabilities of related methods.
Characterization of Biocomposites from Polylactic Acid and Cellulose of Oil Palm Empty Fruit Bunch
Authors: Paramitha Tika , Sitompul Johnner P
Published: February 2022

Biocomposites are polymers reinforced with natural fibers, such as cellulose. This research aims to synthesize cellulose from Oil Palm Empty Fruit Bunch (OPEFB) and biocomposites from PLA and cellulose. In this study, cellulose was obtained through alkalization, hydrolysis, and bleaching of OPEFB. Biocomposites production was carried out by mixing PLA and cellulose using the extrusion method. In the extrusion method, PLA and cellulose of OPEFB were mixed using an extruder above the melting point of PLA of 170°C. The output product of an extruder was then pressed using a compression moulding machine to form biocomposites. The tensile strength of biocomposites had a smaller value than pure PLA, whereas the modulus young of biocomposites with 5% by weight of cellulose had a higher value than pure PLA. The decrease in the mechanical properties of biocomposites was caused by poor adhesion between PLA and cellulose. The water absorption of biocomposites was greater than pure PLA, which was influenced by cellulose's characteristics as hydrophilic and PLA is hydrophobic. Also, the higher water absorption in biocomposites accelerated the weight loss of biodegradability.

The PIM-passive sampler is a passive sampler using PIM as a diffusion layer. This research aimed to optimize the concentration of PIM plasticizer and the concentration of phosphate ions in bulk solution to produce a PIM-passive sampler for phosphate measurement with high accuracy. In this study, a passive sampler was made of a 15 ml glass bottle containing 0.2 M H2SO4 solution as the receiving phase and PIM as a diffusion membrane. PIM was prepared by mixing polyvinyl chloride (PVC) as the base membrane, Aliquat 336-Cl as a carrier, and 1-decanol as a plasticizer. Sampling was done by immersing the passive sampler in the bulk phase solution for three hours. The phosphate concentrations in bulk and receiving phases were determined regularly every 30 minutes using the visible spectrophotometric method at a wavelength of 690 nm. The results showed that the optimum concentration of 1-decanol for PIM was 15% w/w. The higher the plasticiser concentration, the PIM was oily, thus preventing the analyte from contacting the extractant. The range of phosphate ion concentrations in the sample that the PIM-passive sampler could detect was 0.1-1.3 mg P/L. The calibration curve for phosphate measurement was CTWA = 1.0664. Cs – 0.0088 with a correlation coefficient (R2) was 0.9998. This shows that the PIM-passive sampler can be used for the measurement of phosphate ions with high accuracy.

As características morfofisiológicas e biofísicas de clones de palma forrageira foram investigadas neste estudo como indicativo à adequação do manejo da cultura sob prática de irrigação e uso de cobertura morta. O experimento foi conduzido com os clones IPA Sertânia e Miúda, ambos Nopalea cochenillifera (L.) Salm-Dick, e Orelha de Elefante Mexicana, Opuntia stricta (Haw.) Haw., em blocos casualizados, com três repetições, e sob três ambientes de crescimento: RH(-) - regime hídrico inferior à normal climatológica; RH(+) - regime hídrico superior à normal climatológica; e, RH(+C) - regime hídrico superior à normal climatológica e adoção de cobertura morta. Medidas biométricas foram obtidas ao longo do tempo e a matéria seca na ocasião da colheita, a partir dos quais, calculou-se índices morfofisiológicos e biofísicos. Os ambientes de crescimento e sua interação com os clones afetaram apenas a magnitude do índice de distribuição dos cladódios de 5ª ordem (p < 0,05), mas foram decisivos na sazonalidade do acúmulo de matéria seca pelos clones. A maioria dos índices morfofisiológicos e biofísicos foi influenciada pelo tipo de clone (p < 0,05). Os índices biofísicos se mostram ótimas opções de substituição ou complementação dos índices morfofisiológicos quando se dispõem apenas de dados biométricos e de matéria seca da ocasião da colheita da palma forrageira.

EIGEN 6C4 gravity anomalies are interpreted to determine the lateral and vertical variations in the crust and upper mantle structure and their influence on the isostasy of the coastal plain, transition zone between the Congo Craton (CC), the Pan-African Belt (PAB), and adjacent areas. The regional gravity anomalies have been inverted in an attempt to provide a Moho depth map. The inversion process was based on the Parker-Oldenburg method with a density contrast of 0.55 g/cm3 and an average depth reference of 39 km. In addition, various tests have been performed to validate the resulting Moho model and estimate the efficiency of the 3D gravity inversion by varying the density contrast for a fixed Moho reference depth. Inversion results reveal that the Moho depths generally agree with those obtained from previous geophysical studies. The computation of the isostatic models using the ETOPO1 digital elevation model (DEM) and its comparison with the Moho models obtained from gravity induce the following main conclusions: (1) an overcompensated crust beneath the coastal plain and the Yaounde Domain, (2) the crust beneath areas located in the southern end of the Adamawa-Yade Domain is thin and undercompensated, and (3) main volcanoes of the Southwestern Cameroon Volcanic Line (CVL) are isostatically undercompensated. This study also revealed that the local isostatic compensation law is not satisfied for most of the tectonic provinces of the study area, and we suggest alternative tectonic mechanisms to support topography below these tectonic features. Additionally, most seismic events (M>3.5) occurred in areas marked by abrupt changes in compensation amplitude. Thus, we concluded from this study that the northern limit of the CC, the Mount Cameroon, and its surroundings are tectonic extension areas that may play a crucial role in the occurrence of future earthquakes.
