Oil Refinery Heat Exchanger Network Cleaning Scheduling Strategy with Unit Cleanability Consideration
Authors: Huda Hairul , Handogo Renanto , Biyanto Totok Ruki , Wu Wei , Adi Vincentius Surya Kurnia
Published: June 2020

Heat exchanger networks (HENs) play an important role in the chemical industries. Unfortunately, fouling is inevitable in heat exchangers operation. Therefore, the optimal cleaning procedure is required to restore heat exchangers' performance periodically. A systematic cleaning scheduling strategy for the heat exchanger network in an oil refinery is proposed in this work. There are 11 operating heat exchangers in an oil refinery to be reviewed. Different cleaning decision scenarios based on the overall heat transfer coefficient are explored for optimal cleaning schedule performance. The daily number of exchangers available to be cleaned i.e., the unit cleanability, is investigated while minimizing the energy consumption and the additional heat requirement due to the offline heat exchanger under cleaning procedure. The HEN performance and the energy-saving from the cleaning procedures are benchmarked with the uncleaned HEN. The results indicate that the cleaning procedure significantly increases the HEN performance and simultaneously reduces the heat requirement if compared to the untreated HEN benchmark. The possible conflicting situation is discussed when some heat exchangers are waiting to be cleaned due to the unit cleanability restriction, which allows the overall heat transfer coefficient to be below the allowed limit. Therefore, nonconflicting cleaning scheduling is also addressed in this work by relaxing the unit cleanability limit. Furthermore, the optimal cleaning schedule is also suggested for user reference. In this work, the optimum cleaning schedule with minimum energy consumption and maximum energy saving could be achieved when cleaning decision limit is set at 40% decrease of overall heat transfer coefficient. In the contrast, the lowest number of cleaning procedures is associated with 90% decrease in the overall heat transfer coefficient as the cleaning decision limit.

Published: June 2020

Natural gas is one of the cleanest energy resources and may have potency to replace crude oil as main energy resource in several decades. There are some aspects which must be concern in the development of the natural gas industry including processing, storing, distributing and utilizing of the natural gas. The network of natural gas supply also should be generated to obtain the maximum natural gas recovery. However, it is difficult to determine the most suitable network system to connect the supply and demand of natural gas due to their different time scale, flowrate and capacity. There are some studies which investigating the network system to connect the supply and demand of natural gas but there are no systematical method in determination of the optimum natural gas network in single region supply-chain using pinch analysis. Therefore, in this study, a systematical method was developed to design natural gas network system in single region (East Java) using pinch analysis. The concept of natural gas cascade calculation was introduced. The heuristics of natural gas pairing between source and sink streams in grid diagram analysis was developed. Using 0-year time minimum difference give the amount of unutilized supply with value of 258.4 billion standard cubic feet (BCF) while 3-year time minimum difference give the amount of alternative and unutilized supply with value of 639.3 BCF and 897.7 BCF, respectively. The grid diagram heuristics developed in this study gives same results with the cascade calculation result.

Published: June 2020

A method known as Bicarbonate-based Integrated Carbon Capture andAlgae Production System (BICCAPS), is a growing study introduced as an alternative to current carbon capture and sequestration (CCS) methods. It is a closed-loop cycle involving inorganic carbon in the form of bicarbonates, which is consumed by microalgae for growth and utilizes the regenerated carbonates for another cycle of carbon capture. Existing literature requires more in-depth experimentation and analysis with regards to the viability of different microorganisms to the rising method. Spirulina platensis was evaluated in BICCAPS using 0.1M Na2CO3, employing three different culture media for growth, namely, modified Zarrouk’s, NPK- based, and NPK- based with A5 solution media. Biomass growth, productivity, and carbon dioxide utilization were investigated to determine the effectivity of BICCAPS as a carbon sequestration technique. At control conditions, NPK-based with A5 solution medium yielded the highest productivity with a value of 10.81 mg L-1 day-1. Likewise, using NaHCO3 as a carbon source, results show that the highest productivity was achieved also under NPK- based with A5 solution medium with a value of 6.80 mg L-1 day-1, as well as a high carbon conversion value of 2.092 day-1.

Published: June 2020

A combination of the experimental and numerical methods was used to investigate the fluid flow behaviors in a proposed cyclone burner. Recirculation flow and pressure drop, two of the important fluid flow behaviors that affect the burner's performance, have been studied here. Experimentally, the recirculation flow phenomenon in the burner was observed through paper slices dynamic in a transparent burner, and pressure drop was measured using a tube manometer. Meanwhile numerically, the fluid flow behaviors were simulated using the standard k-e turbulence model, under Ansys-Fluent software. The simulation results showed that, at a certain value of inlet aspect ratio (RIA) and initial tangential intensity (IIT), especially for high IIT, the recirculation flow phenomenon was clearly observed in the center of the burner cylinder which closely resembles a tornado-tail. The indication of existence recirculation flow was also found from the experiment results. The study also exhibited that the results of simulated static pressure drop were closely approaching the experiment results, particularly for IIT values £ 4.3. The mean deviation of static pressure between the simulation and the experiment results, for a varied range of RIA and IIT,was about 15%. From the results above, it was obvious that fluid flow behaviors (recirculation flow and static pressure) in the proposed cyclone burner are greatly influenced by the RIA and IIT values, where the IIT effect was more significant compared to the RIA. This study also suggests that, the standard k-e turbulence model could be relied upon to well predict the behaviors of fluid flow in the proposed cyclone burner, at low to moderate swirl intensities.

HOW DOES ISLAMIC BANKING SUPPORT ECONOMICS GROWTH?
Authors: Mifrahi Mustika Noor , Tohirin Achmad
Published: June 2020

Some researchers have argued that the financial system has a vital role in economic growth. Islamic banking that has existed widely in many countries is expected to have a positive role in economic growth. This study aims to examine the impact of Islamic bank financing on economic growth in QISMUT countries. To compare with other full Islamic banking systems, Iran and Sudan also included in this study. By using annual panel data (2005-2015), this paper utilizes an approach to multiple mediating analysis models. The findings demonstrate that Islamic banking financing does not significantly impact economic growth directly. However, Islamic banking financing can possibly influence economic growth indirectly through investment and consumption spending.========================================================================================================Bagaimanakah Peran Perbankan Syariah dalam Pertumbuhan Ekonomi? Beberapa peneliti berpendapat bahwa system keuangan memiliki peran penting dalam pertumbuhan ekonomi. Perbankan Islam yang telah ada secara luas di banyak negara diduga memiliki peran positif dalam pertumbuhan ekonomi.

Iran dan Sudan dimasukkan dalam objek penelitian ini sebagai pembanding penggunaan sistem keuangan Islam. Menggunakan data panel tahun 2005-2015, penelitian ini menggunakan pendekatan analisis media dengan banyak faktor. Hasil penelitian menunjukkan bahwa pembiayaan bank Islam tidak dapat mempengaruhi pertumbuhan ekonomi secara langsung. Akan tetapi, Bank Islam dapat mempengaruhi pertumbuhan ekonomi secara tidak langsung, yaitu melaui investasi dan konsumsi.
Maslahat as Considerations of Islamic Law in View Imam Malik
Authors: Syarifuddin Said
Published: June 2020

This study aims to reveal the view of Imam Malik about maslahat as an independent proposition in the determination of Islamic law. Trying to explain the terminology of maslahat, uncovering the dimensions of maslahat in the determination of Islamic law, analyzing maslahat as a basis of Islamic law that stands alone to establish Islamic law according to Imam Malik, and citing examples of Imam Malik's fatwa based on consideration of maslahat. This paper is a qualitative descriptive study using a multidisciplinary approach including normative, philosophical, and sociological approaches. This study shows that maslahat contains two sides, namely attracting or bringing benefit and rejecting or avoiding harm in order to maintain the goals of shari'ah, the establishment of Islamic law aims at realizing human benefit that is universal, generally accepted and lasting for all humans and in all circumstances. Imam Malik is of the view that maslahat can be used as a basis for independent legal considerations, without the need for legitimation of the shar'i proposition. For example, Imam Malik establishes the saliva of a holy dog. The fatwa is not in line with the instructions of the hadith that classify it as unclean. Imam Malik was not the first scholar to settle such a law, but his companions had experienced such cases, they then resolved these problems by issuing fatwas that were "contrary to" the instructions of zhahir nas. Therefore, the renewal of Islamic law can be done through maslahat considerations, such as those taken by Imam Malik, in order to provide legal answers to problems faced by the community, so that Islamic law appears to live dynamically in a society that continues to experience changes and developments.
Harm Reduction: Assessing the Educational Needs of Family Medicine Residents in Care of Persons Who Inject Drugs
Authors: Sell Jarrett , Visconti Adam
Published: June 2020

Background and Objectives: Rates of injection drug use and associated medical complications have increased, yet engagement of persons who inject drugs (PWID) in primary care is limited, with significant barriers to care. Family physicians play an important role in caring for PWID, but residency training is limited. This study aimed to assess role responsibility, self-efficacy, and attitudes of family medicine residents in caring for PWID.
Methods: Using a cross sectional design, family medicine residents in 2018 at three different programs completed Likert and open-ended survey questions assessing role responsibility, self-efficacy, and attitudes in caring for PWID.
Results: Fifty-five percent (41/76) of residents completed surveys. Residents consistently agreed it is their responsibility to provide comprehensive care for PWID, while being less confident in key elements of screening, brief intervention, and referral to treatment (SBIRT). The largest gap between responsibility and confidence was in referral to treatment. Resident confidence was lowest for harm reduction strategies: discussing clean needle practices, prescribing naloxone and referral to medication-assisted treatment or needle exchange programs. Less than 60% of residents agreed they are able to work with or understand PWID.
Conclusions: This study identifies gaps between provider responsibility and current graduate medical education training. We identified training that increases screening, harm reduction practices, and referrals to community resources as needs. This baseline assessment of family medicine residents can be used to develop educational interventions to meet regional and national health needs for harm reduction for PWID and workforce development.

Authors: Flynn Mary M. , Monteiro Kristina , George Paul , Tunkel Allan R.
Published: June 2020

Background and Objectives: Food insecurity, defined as the lack of reliable access to sufficient quantities of affordable, nutritious food and present in 11.1% of the general population, has not been assessed in medical students. Food insecurity is related to adverse outcomes for both health and academics in undergraduate students. Assessing the presence of food insecurity in medical students, a population at high risk for burnout and depression, may allow for intervention in order to improve overall wellness in this population. The objectives of this study were to assess the prevalence of food insecurity in a medical student population and identify potential reasons for any measured food insecurity.
Methods: We used a questionnaire that included the US Household Food Security Survey Module: Six-Item Short Form. The survey was emailed to all students enrolled at a Northeastern medical school (N=588) to assess food insecurity in the previous 3 months. The questionnaire included potential reasons for food insecurity.
Results: The survey response rate was 22.4%. Food insecurity was present in 11.8% of these respondents. The main reasons selected for food insecurity were not being able to get to the store (33.9%), followed by insufficient funds (30.4%).
Conclusions: Prevalence of food insecurity in medical students may be similar to the general population. While the results of this study represent only one medical school, we believe these results are similar at other medical schools. Interventions to reduce food insecurity in this population are necessary to improve overall student wellness.

Background and Objectives: Schools of medicine in the United States may overstate the placement of their graduates in primary care. The purpose of this project was to determine the magnitude by which primary care output is overestimated by commonly used metrics and identify a more accurate method for predicting actual primary care output.
Methods: We used a retrospective cohort study with a convenience sample of graduates from US medical schools granting the MD degree. We determined the actual practicing specialty of those graduates considered primary care based on the Residency Match Method by using a variety of online sources. Analyses compared the percentage of graduates actually practicing primary care between the Residency Match Method and the Intent to Practice Primary Care Method.
Results: The final study population included 17,509 graduates from 20 campuses across 14 university systems widely distributed across the United States and widely varying in published ranking for producing primary care graduates. The commonly used Residency Match Method predicted a 41.2% primary care output rate. The actual primary care output rate was 22.3%. The proposed new method, the Intent to Practice Primary Care Method, predicted a 17.1% primary care output rate, which was closer to the actual primary care rate.
Conclusions: A valid, reliable method of predicting primary care output is essential for workforce training and planning. Medical schools, administrators, policy makers, and popular press should adopt this new, more reliable primary care reporting method.
A Rare Case of Secondary Cutis Verticis Gyrata on the Forehead
Authors: Jung Joo Sung , Lim Nam Kyu
Published: June 2020

Cutis verticis gyrata (CVG) is an unusual morphological condition of the scalp characterized by ridges and furrows resembling the surface of the brain. Most patients have lesions on the scalp, and only a few cases with forehead lesions have been described in literature. We report an extremely rare case of secondary CVG on the forehead. A 61-year-old female patient was referred to our outpatient clinic with a large area of hypertrophic skin on the forehead. A lesion measuring 12×3 cm extended across both eyebrows, the glabella, and the forehead. The patient reported that a pruritic erythematous lesion in that region had occurred 10 years ago after she performed acupuncture on herself on the forehead several times. She had no underlying diseases and no relevant family history. We removed the entire lesion and covered the defect with a forehead advancement flap. This solved the initial aesthetic problem. Her forehead skin became flattened, and the sagging upper eyelid skin was aesthetically corrected. Pathological findings showed nodular lesions with dense collagen fibers and microvascular proliferation, supporting the diagnosis of CVG. We achieved good results through surgical treatment for the extremely rare case of CVG on the forehead.

Published: June 2020

Nicolau syndrome is a rare iatrogenic adverse reaction caused by intramuscular injection of various medications. The clinical features include pain, erythematous swelling, infection, and local ischemic necrosis, but the pathogenesis is uncertain. This study presents the first case of Nicolau syndrome that presented with skin and soft tissue necrosis on both buttocks caused by the antibiotic agent kanamycin, which is used to treat multidrug-resistant tuberculosis. A 62-year-old man was referred due to infectious skin and soft tissue necrosis on both buttock areas. He received intramuscular kanamycin injections to both buttocks to treat pulmonary tuberculosis 4 months before presentation. After extensive debridement, skin and soft tissue defects sized approximately 10.0×6.0 cm and 5.0×5.0 cm were found on the right and left buttock, respectively, and two transpositional fasciocutaneous flaps were designed to cover the defects. The wounds healed without any complications. Nicolau syndrome has various presentations and, in rare cases, can be fatal. In this case, the patient presented with skin and fat necrosis superimposed with an infectious condition, which required immediate and extensive debridement.
Reverse Posterior Interosseous Artery Flap: A Reliable, Comfortable and Versatile Flap for Coverage of Soft Tissue Defects of Hand
Authors: Khurram Mohammed Fahud , Maurya Sudheer Kumar , Yaseen Mohd , Chowdhry Madhav
Published: June 2020

Background: Soft tissue defects of the hands require coverage with soft, pliable full-thickness skin. The posterior interosseous artery (PIA) flap fulfils all these requirements and also has significant advantages over other flaps; it is a single-stage procedure that does not sacrifice major vascular axis of the hand. However, the dissection can be challenging and requires meticulous skill. The objective of the study was to evaluate the reverse PIA flap for coverage of hand soft tissue defects in terms of its safety, reliability, comfort, function and aesthetic appearance.Methods: Over a period of 3 years, patients with soft tissue defects over the dorsum of the hand and first web space were observed. A standard PIA flap was raised using loupe magnification under general or brachial anesthesia. The size and location of the defect were noted along with the size and success of the flap.Results: Twelve patients, including nine males and three females, were taken up for this procedure. All the flaps survived completely except one with marginal necrosis not requiring a secondary procedure. All patients were quite satisfied with the procedure and went on to resume their work within a month or two.Conclusion: PIA flap is a safe, reliable option with great versatility for coverage of hand defects, especially over the dorsum. A well-planned flap surgery done under loupe magnification affords excellent results. The entire treatment also requires a shorter hospital stay and allows the patient to return to work quickly.

Authors: BİLGİN ŞİMŞEK Esra , ALKAY Taner
Published: June 2020

A three-layer Artificial Neural Network (ANN) model was employed to develop and estimate the effluent stream parameters of two different wastewater treatment plants (WWTP) in Kocaeli, Turkey. The chemical oxygen demand (COD), suspended solid (SS), pH and temperature as the output parameters were estimated by five input parameters such as flow rate, COD, pH, SS and temperature. The ANN model was developed with 400 data sets for prediction of effluent pH, temperature, COD and SS. The benchmark tests were employed to achieve an optimum network algorithm. The network model with optimum functions at hidden and output layers were applied for the forecasts of effluent streams of both WWTPs. The regression values of training, validation and test using this function were found as 0.94, 0.96 and 0.95, respectively. The optimum neuron numbers were determined according to the minimum mean square error values. ANN testing outputs revealed that the model exhibited well performance in forecasting the effluent pH, temperature, SS and COD values.

Ivory tower and barricades: Marcuse and Adorno on the separation of theory and praxis
Authors: Visic Maroje
Published: June 2020

The events of 1968/69 initiated a dispute between Adorno and Marcuse over the
(alleged) separation of theory and praxis. While Marcuse ?stood at the
barricades? Adorno sought recluse in the ?ivory tower?. Marcuse and German
students perceived Adorno?s move as departure from fundamental postulates of
critical theory as laid down in Horkheimer?s 1937 essay. Adorno died amidst
the process of clarifying his differences with Marcuse and thus the
?unlimited discussions? between the two remain unfinished. This paper sets
to examine how both Marcuse and Adorno remained dedicated to the unity of
theory and praxis, albeit in different ways. I argue that Adorno did not
separate theory and praxis; instead, he perceived the gap between critical
theory and concrete historical situation. Adorno rejected simple and
unreflective translation of theory into praxis. Hence his attempt to
recalibrate critical theory. Marcuse?s and Adorno?s differences lie in their
different evaluation of the student movement and this (mis)evaluation was
context related. My second argument is that Marcuse/Adorno disagreement is
partly caused by the absence of the two from the concrete historical
context.

Authors: Peric Tamara , Markovic Dejan , Tomic-Spiric Vesna , Petrovic Bojan , Peric-Popadic Aleksandra , Markovic Evgenija
Published: June 2020

Introduction/Objective. The purpose of this study was to compare clinical efficacy of casein phosphopeptide ? amorphous calcium phosphate (CPP-ACP) and casein phosphopeptide-amorphous calcium fluoride phosphate (CPP-ACFP) with 0.05% NaF, and to assess their influence on the quality of life among individuals with Sjogren?s syndrome. Methods. Thirty patients were randomized into three groups treated with different remineralizing agents: CPP-ACP, CPP-ACFP, and 0.05% NaF. Oral health was evaluated at the beginning of the study, after 28 days (short-term effects), and after six months. The diagnosis of dental caries was performed using the decayed, missing, and filled teeth (DMFT) / decayed and filled surfaces (DFS) criteria. Enamel demineralization was visually examined using the white spot lesion index (Gorelick). The gingival health was evaluated with the gingival index (Loe?Silness). Assessment of oral hygiene was done using the simplified oral hygiene index (Greene?Vermilion). The Xerostomia Inventory was used to quantify dry-mouth symptoms. The oral health-related quality of life was analyzed using the short form of the Oral Health Impact Profile (OHIP-14). Results. During the evaluation period, caries increment was not significant. Considerable regression of white spot lesions was noted in all three experimental groups (p < 0.001). No significant improvement in gingival health and oral hygiene was observed. Physical pain was decreased in all three experimental groups, and subjective feeling of dry mouth was reduced in CPP-ACP and CPP-ACFP groups. Conclusion. CPP-ACP and CPP-ACFP may reduce the caries activity and relieve the dry-mouth symptoms in patients with Sjogren?s syndrome.

De modo geral, observamos, a partir do discurso coletivo dos alunos, que há diversas razões para compreender por que as tecnologias nos aproximam do processo de ensino a distância, entretanto um dos achados da pesquisa, revelam a utilização do Google Earth, a partir de uma abordagem geográfica da natureza.
NARRATIVAS DIGITAIS E EXPERIÊNCIA: EXPLORAÇÃO DE CONCEITOS E IMPLICAÇÕES PARA A EDUCAÇÃO EM UMA PERSPECTIVA HUMANISTA
Authors: Rodrigues Alessandra
Published: June 2020

As discussões sobre a temática das narrativas digitais têm se expandido, nos últimos anos, em diferentes áreas do conhecimento – desde o Design e a Comunicação até a Educação e a Linguagem. Ainda assim, escassos são os estudos dedicados a uma abordagem conceitual do tema. Nesse contexto, este artigo resulta de uma revisão narrativa de literatura e apresenta um estudo teórico-conceitual acerca das narrativas digitais em diálogo com o conceito de experiência em Heidegger (2003) e Larrosa (2002; 2004; 2011a; 2011b). Desde essas perspectivas, em interlocução com a área da Educação e com autores que defendem que ela seja humanista e emancipatória, o texto explora os dois conceitos (narrativas digitais e experiência). A partir daí, o estudo busca indicar caminhos possíveis para integração dessas narrativas à prática docente e aos currículos em diferentes contextos formativos para uma educação mediada pelas tecnologias que contribua para que o humanismo se mantenha como o fundamento de nossas relações também no contexto da cultura digital.

O presente trabalho tem o objetivo de apresentar resultados obtidos em uma experiência envolvendo o uso de tecnologias no ensino de Matemática em uma turma de calouros do curso de Engenharia Elétrica. A partir da literatura consultada, considera-se que a inserção das tecnologias no ambiente de ensino pode possibilitar que os alunos construam seus próprios conhecimentos e assumam um papel ativo nesta construção. Buscando ilustrar sua utilização e benefícios em sala de aula, foi desenvolvida uma atividade que faz uso do software GeoGebra cujo objetivo principal era estudar as funções trigonométricas e suas propriedades. Os resultados mostraram que o uso do software GeoGebra contribuiu para a compreensão dos conceitos envolvidos, para o desenvolvimento da capacidade de análise e argumentação, para a socialização e colaboração dos discentes durante o desenvolvimento da atividade, para a motivação para o estudo e para a inserção dos estudantes em um ambiente de ensino com uso de tecnologias.
Bpop: an efficient program for estimating base population allele frequencies in single and multiple group structured populations
Authors: Stranden Ismo , Mäntysaari Esa A.
Published: June 2020

Base population allele frequencies (AF) should be used in genomic evaluations. A program named Bpop was implemented to estimate base population AF using a generalized least squares (GLS) method when the base population individuals can be assigned to groups. The required dense matrix products involving (A22 )-1v were implemented efficiently using sparse submatrices of A-1, where A and A22 are pedigree relationship matrices for all and genotyped animals, respectively. Three approaches were implemented: iteration on pedigree (IOP), iteration in memory (IM), and direct inversion by sparsity preserving Cholesky decomposition (CHM). The test data had 1.5 million animals genotyped using 50240 markers. Total computing time (the product (A22)-11) was 53 min (1.2 min) by IOP, 51 min (0.3 min) by IM, and 56 min (4.6 min) by CHM. Peak computer core memory use was 0.67 GB by IOP, 0.80 GB by IM, and 7.53 GB by CHM. Thus, the IOP and IM approaches can be recommended for large data sets because of their low memory use and computing time.

Published: June 2020

Climate change is not something scary, dangerous. Urgent, exceptional and most importantly is that climate change was not known when it happened. And the thing to do is not frightened by the climate change, but it must be to explain to the people and groups that climate change is inevitable and things to do is to minimize the impact of climate change. One of them is by not cutting down trees carelessly, can manage waste and preserve family environment such as that done by the community Pangerwangi village, Lembang, West Java. The village which has been awarded as the climate village for being able to survive and adapt to climate change .. Because the essence of Kampung climate is how the community to survive and adapt to the climate because it is people who have to adjust to the climate. And achievements that have been achieved not in spite of community participation and community-based organizations.
El rol de Brasil en el regionalismo latinoamericano: la apuesta por una inserción internacional solitaria y unilateral
Authors: Vadell Javier A. , Giaccaglia Clarisa
Published: June 2020

A inicios del siglo xxi, Brasil se constituyó en un protagonista crucial como principal articulador del proyecto integracionista de Sudamérica. Al ya existente Mercosur se le sumó la creación de Unasur, reafirmando la construcción de políticas regionales en torno a la idea de “Sudamérica”. En la actualidad, sin embargo, la retracción del liderazgo brasileño, junto con los virajes y desorientaciones ocurridos en Unasur y en Mercosur, han dañado la credibilidad de las iniciativas de la región, así como la posibilidad de identificar una voz conjunta en Sudamérica. Pese a ello, creemos que difícilmente podría hablarse de un desacoplamiento total de Brasil de la subregión o, dicho de otro modo, de un abandono efectivo de los regionalismos. El reconocimiento de las vicisitudes distintivas por las que han atravesado los Estados latinoamericanos nos lleva más bien a pensar en un entramado complejo y desordenado, en el cual el devenir político institucional de Brasil tendrá relevantes repercusiones para el futuro de la región.
El comercio México-Guatemala: retos y oportunidades para mejorar la relación bilateral
Authors: De la Mora Luz María
Published: June 2020

Este trabajo analiza la dinámica y los retos del comercio transfronterizo México-Guatemala. Ofrece un diagnóstico sobre la dinámica del comercio y las inversiones entre ambos países y aporta recomendaciones precisas para impulsar el desarrollo de la región fronteriza vía la inversión productiva y el comercio. La eliminación de aranceles al comercio bilateral en el marco del tratado de libre comercio no ha sido suficiente para detonarlo debido a barreras regulatorias, burocráticas y administrativas, además de deficiencias institucionales y de infraestructura. Se sugiere que, para optimizar el comercio y la inversión entre ambos países, los gobiernos nacionales y estatales den prioridad a la relación bilateral en las agendas de política exterior de ambos, lo que tendría que materializarse con recursos económicos, políticos y humanos.
The Vagueness of Religious Beliefs
Authors: Bertini Daniele
Published: June 2020

My paper characterizes religious beliefs in terms of vagueness. I introduce my topic by providing a general overview of my main claims. In the subsequent section, I develop basic distinctions and terminology for handling the notion of religious tradition and capturing (religious) vagueness. In the following sections, I make the case for my claim that religious beliefs are vague by developing a general argument from the interconnection between the referential opacity of religious belief content and the long-term communitarian history of the precisification of what such content means. I start from describing an empirical example in the third section, and then I move to settle the matter in a conceptually argumentative frame in the fourth one. My conclusions in the final section address a few of consequences relevant to debates about religious epistemology and religious diversity.
Religious Protest and Religious Loyalty
Authors: Sagi Avi , Sagi Nir
Published: June 2020

In the accepted view, the basic disposition of believers is one of absolute obedience, humility, and lack of critique, doubt, or, indeed, defiance of God. Only through such a disposition do believers convey their absolute faith and establish the appropriate hierarchy between God and humans. This article challenges this view and argues that, in mainstream rabbinic tradition, the believer is not required to renounce his or her moral autonomy and certainly not his or her understanding of God and the world. Indeed, faith rests on such understanding; moreover, human autonomy is the mechanism through which humans convey God’s goodness and perfection. Their questions and criticism are part of a persistent effort to close the evident gap between their assumptions about God’s goodness and the flawed imperfect reality. The analysis focuses on rabbinic tradition but its implications go beyond it, presenting a model of a life of faith that compels subjects, as believers, to preserve their constitutive foundations as rational autonomous creatures.

Estudo que objetivou conhecer a percepção dos jovens universitários acerca da sexualidade e descrever as condutas sexuais dos estudantes em seus relacionamentos. Pesquisa descritiva, qualitativa, realizada numa instituição de ensino superior privada, no Rio de Janeiro, com universitários de 18-29 anos. Dados coletados com emprego da técnica de grupo focal, sendo analisados com a técnica de análise de conteúdo temático-categorial, com auxílio do software Nvivo 9.0. Emergiram três categorias, sendo apresentadas neste artigo: relacionamentos, iniciação sexual e o diálogo com as crenças religiosas na perspectiva dos jovens universitários. As condutas sexuais do grupo são influenciadas pela cultura, religiosidade e relações entre os gêneros, e há interferência desses aspectos no entendimento desses conceitos. Os universitários se ressentem de uma maior participação dos pais na sua orientação sexual. A educação em saúde para orientação e preservação da saúde sexual e prevenção de agravos do grupo jovem é uma prática fundamental e necessária.
