La Corte Constitucional ecuatoriana en la gobernanza del riesgo ante la COVID-19
Authors: Cahueñas Muñoz Hugo
Published: July 2021

Basado en un enfoque de gobernanza del riesgo de desastres, el artículo analiza los dictámenes de la Corte Constitucional del Ecuador ante los estados de excepción adopta-dos por la COVID-19 hasta enero de 2021. Se divide el análisis en tres momentos: a) los primeros dictámenes, donde la Corte presenta exhortos y recomendaciones; b) el dictamen No. 5-20-EE/20 donde se pone un ultimátum a los decretos de estados de excepción, se exige adoptar un régimen ordinario para responder a la COVID-19 y se iden-tifica marcos normativos ordinarios para gestionar la respuesta a la COVID-19; y, c) el dictamen No. 7-20-EE/20 donde la Corte Constitucional determina que el decreto de estado de excepción es inconstitucional. A lo largo de los dictámenes, la Corte también hace un exhorto por la adopción de una ley para responder a la pandemia. Bajo un enfoque de gobernanza del riesgo de desastres, resulta imperante adoptar un marco jurídico e institucional para la gestión integral de los riesgos de desastres, no solo por esta situación de la COVID-19, sino en general, un régimen ordinario que permita fortalecer las capacidades y disminuir las vulnerabilidades ante los riesgos de desastres. De igual manera, en futuros dictámenes de constitucionalidad relacionados con desastres, la Corte Consti-tucional debe tener en cuenta los parámetros internacionales de reducción del riesgo de desastres que buscan proteger los derechos de las personas.

Published: July 2021

El papel del modelado estadístico en la gestión de emergencias es fundamental para perfilar o apoyar las decisiones en torno a la atención de los eventos. En 2020 con el surgimiento de la pandemia por coronavirus, los países rápidamente se prepararon para la atención del comportamiento de contagio y el impacto que tendría en la salud pública. En Costa Rica, un equipo de especialistas preparó estudios sobre el comportamiento de la curva de contagio y su efecto en la ocupación de camas hospitalarias durante los primeros tres meses de la presencia de la epidemia. Los estudios se basaron en la estimación de modelos estadísticos de crecimiento exponencial y logístico, los cuales proporcionaron los pronósticos del número de casos diarios y acumulados. La predicción de casos permitió alimentar un modelo de simulación para la proyección de demanda de camas hospitalarias por pacientes de la COVID-19. Los análisis se basaron en los datos aportados por el Ministerio de Salud en torno a los casos confirmados por coronavirus desde la aparición del primer caso en Costa Rica. Se estimaron cuatro modelos: logístico, Richards, Gompertz y exponencial, los cuales generaron la predicción de casos diarios. También se estimó el número de reproducibilidad mediante estadística bayesiana para cuantificar la transmisibilidad del virus. Los resultados permitieron anticipar el comportamiento inicial del virus en Costa Rica y el potencial efecto de las medidas de contención que se adopta-ron a partir de la declaratoria de emergencia nacional.

Dynamic Impact Factor Determination of an Existing Pre-stressed Concrete I-Girder Bridge Using Vehicle-Bridge Interaction Modelling
Authors: Adhikary Shuvrodeb , Rana Shohel , Tasnim Jerin , Islam Nazrul
Published: July 2021

The dynamic Impact Factor (IM) of a bridge is influenced by many factors, including Vehicle-Bridge Interaction (VBI), vehicle speed and road roughness. This paper represents the dynamic effects of moving vehicles and the determination of IM of an existing Pre-stressed concrete I-girder bridge utilizing VBI modeling. Evaluation of the IM is expected to provide valuable information for condition assessment and management of the existing bridge. The interaction problem between the vehicle and the bridge includes a dynamic model for the bridge structure subsystem, a dynamic model for the vehicle subsystem, interaction constraints, road roughness modelling and numerical solution techniques for the dynamic systems. The Half-car model is utilized for modelling of the vehicle dynamics and the bridge dynamic model is idealized according to Finite Element Method (FEM). Then FEM along with the mode superposition method are utilized for determining the Equation of Motion (EOM) for the bridge subsystem. D’Alembert’s principle is used for developing EOM for the vehicle subsystem. The interaction between vehicle vibration and bridge vibration is established through the contact forces between the wheels and the bridge by employing the compatibility relationship between the contact points and by applying the static equilibrium condition. Lastly, Newmark’s-? method is used for solving the coupled mathematical model of the vehicle and bridge interaction problem to determine the responses of the two sub-systems. The whole procedure is then performed for different vehicle speeds and various bridge deck surface roughness conditions to determine the dynamic impact on the existing I-girder bridge named Teesta Bridge located in Bangladesh.

Gris: metáfora, símbolo y relato en (inter)acción.
Authors:   Universidad Autónoma del Estado de Morelos (MÉXICO), Borunda Magallanes Ismael Antonio
Published: July 2021

Gris, an independent Spanish video game, explores the expressive possibilities of this creative medium through a story that is, on one hand, a symbolic representation of the psychological process of the protagonist, and, on the other hand, a foundational narrative about the loss and recovery of identity. This title employs the expressive tools of the history of art to build its aesthetic proposal; in particular, it is categorically placed in the line of surrealism as an artistic current. The analysis of this elements is realized through fundamental notions of rhetoric and poetics, referencing authors such as Helena Beristáin and Carmen Bobes, and the narrative hermeneutics of Paul Ricoeur, as well as theoretical perspectives that allow building bridges of analysis between literature and the visual arts.

Published: July 2021

The essence is nothing other than, in addition to being a phenomenological act, it is the interpretation and mental exercise. This exercise answers what makes tourism tourism? And what makes marketing be marketing? The aim is to try out the essence of tourism and marketing from phenomenological reflections. The phenomenological method is the study of intentional analysis, as an intuitive and reflective act. The essence of tourism and marketing, as well as of anything, is not limited to its mere purpose or utility, that is, it exceeds the sine que non conditions of the thing.
Quentin Meillassoux. Realismo especulativo y Narrativas desde la Contingencia.
Authors:   Universidad Autónoma de la Ciudad de México (MÉXICO), Navarro Fuentes Carlos Alberto
Published: July 2021

The objective of this work is to introduce Quentin Meillassoux's 'speculative materialist realism', establishing a critical stance against the metaphysical tradition of the 'absolute' that has prevailed in post-Kantian Western philosophy, based on the need for contingency that he proposes. This implies making a critique of what has been understood as realism, necessity and existing. To do this, key concepts of Meillassoux's philosophy are broken down, exemplifying its influence -and possible presence back in time- on other thinkers and artists in their respective narratives such as Graham Harman, Timothy Morton, Nick Land, and Florian Hecker, who delve into issues that generate discomfort, amazement, nihilism and pessimism in contemporary societies, such as probability and prediction in financial markets, the Anthropocene and nature, the conflictive relationship between subject and object, truth and chaos, between other things, subtracting ourselves from the humanist discourse on which the scientific, financial and environmental paradigms of our time rest and which have ended up cracking the identity of man, with capitalist production being the most determining geological factor. Let us to reflect on the following questions. What narratives can give an account of the current condition of the world? What narratives emerge when we stop focusing our attention on man? What habits of thought force us to change the awareness that everything around us is contingent?
Why the incidence in dialysis in the Lisbon and Tagus Valley Region (LVTR) is two to three times higher than in other regions of the country
Authors:   Professor of Nephrology, Prata Martins
Published: July 2021

The analysis of data from the Ministry of Health’s Integrated Chronic Kidney Disease Management Platform (PI -GID), reveals the existence of a striking regional difference in the incidence in dialysis. This difference is characterized by high levels of incidence in all regions, except the Alentejo, and extremely high levels in the Lisbon and Tagus Valley region. In this region, the incidence values are two to three times higher than in the others. The difference between regions is the result of a different number of patients starting hemodialysis, since the incidence in peritoneal dialysis is low and similar in all of them. It is difficult to find justification for such a discrepancy since the prevalence of factors usually responsible for the higher or lower level of incidence in dialysis does not differ significantly between them. A probable explanation may lie in the difference found in the concentration of public hemodialysis centers, a fact that may determine a difference in the criteria used for the entry of patients undergoing substitutive treatment of renal function. In fact, we found a close correlation between the number of public hemodialysis centers per million inhabitants and the level of incidence in dialysis. A more comprehensive analysis of the data from the Ministry of Health’s Integrated Chronic Kidney Disease Management Platform (PI -GID), if allowed, would be of enormous interest, not only to explain this discrepancy in the incidence of dialysis between regions, but because it could probably allow an explanation for Portugal having (one of) the highest levels of dialysis incidence in Europe
Bioethanol Production from Oil Palm Empty Fruit Bunches Using Saccharomyces cerevisiae Immobilized on Sodium Alginate Beads

Published: July 2021

Bioethanol is an environmentally benign renewable energy commonly obtained from glucose fermentation using Saccharomyces cerevisiae. The purposes of this study are to investigate the effects of time, temperature, pH, immobilized yeast cell loading, beads reuse during ethanol production through batch fermentation of glucose derived from oil palm empty fruit bunches by S. cerevisiae immobilized on Na-alginate beads and to compare the performance of fermentation using immobilized yeast cells and that of using a free cell system. The results revealed that time, temperature, pH, yeast mass and beads reuse significantly affected the ethanol and final glucose concentrations. As expected, a maximum ethanol concentration was obtained from fermentation using immobilized yeast cells at 30 °C, pH 5, and immobilized yeast cell loading of 0.75 g for 48 hours. However, fermentation with a free cell system at the same conditions resulted in lower ethanol yield. The highest ethanol concentration of 88.125 g/L with a productivity of 1.84 g/L·h was achieved from the second cycle fermentation using of immobilized cells beads. The results suggest that an immobilized cell system exhibits great potential applications for improved ethanol production due to its ability to sustain the stability of cell activity, reduce contamination tendency, and protect yeast cells from any possible inhibitions.

Published: July 2021

Drought is one of the main abiotic factors limiting agricultural productivity, capable of having a major impact on the yield of most crops. The knowledge of the physiological and biochemical mechanisms that differentiate resistance and susceptibility to water deficit among soybean strains can be used in the generation of more tolerant cultivars. In this sense, the objective of this study was to characterize physiologically, two soybean cultivars with different patterns of tolerance to drought in the field, by determining photosynthetic rates, lipid peroxidation levels and antioxidant enzyme activity under three levels of water potential. Upon reaching the V4 development stage, the irrigation of the plants was suspended and three data collection were performed: full irrigation (control); moderate water deficit (Ψ = -1.5 ± 0.2 MPa) and severe deficit (Ψ = -3.0 MPa ± 0.2 MPa). Variations in perspiration rate, stomatal conductance, as well as decrease in photosynthetic rate were significant between the two cultivars, where the water potentials in cultivar BR 16 anticipated on average two days achieving the same water potentials in Embrapa 48 cultivar, thus presenting better efficiency in water use. In addition, the increased activity of enzymes and lipid peroxidation were more significant in the cultivar BR 16, demonstrating that this cultivar is less tolerant to drought than Embrapa 48 cultivar, corroborating to agronomic data previously found in the field.
Lermontov’s ‘The Dream’, Chekhov’s ‘Dreams’: at the Brink of Life and Death
Authors: Festic Fatima
Published: July 2021

This text offers a comparative analysis of a lyric poem, The Dream (1841) by Mikhail Yurievich Lermontov and a short story, Dreams (1886) by Anton Pavlovich Chekhov, two major Russian authors embedded in the rigid Russian imperial structures. I examine their dream concepts and figurations, and their representations of various structures that permeate the human existence and human experience of the empire, as well as their poetic irony that comes as their brink. Further, I elucidate the meaning and function of the poetics and aesthetics of the written dream in the societal and political reality of life. The texts is outlined with the paradigmatic Shakespeare’s words from “The Tempest:” “We are such stuff as dreams are made on, and our little life is rounded with a sleep”.
Sebeok, Language and Communication
Authors:   University of Bari Italy, Petrilli Susan , Ponzio Augusto ,   University of Bari, Italy
Published: July 2021

Developing and specifying Charles Peirce’s idea that the entire universe is perfused by signs, Charles Morris recognized that semiotics could be extended to the organic in its wholeness: for there to be a sign there must be interpretive activity by the living organism (cf. Petrilli 1999). Following Morris (1971), Thomas Sebeok developed this thesis to claim that the entire life sphere is made of signs. This means that even a microorganism, for example a cell, flourishes insofar as it interprets signs. Sebeok extends the boundaries of semiotics to a maximum degree with his “semiotics of life” or “global semiotics” which posits that life and semiosis converge. Anthroposemiosis is only a small part of the overall biosemiosic network. And within the sphere of anthroposemiosis an even smaller part is represented by verbal semiosis. Like all other animals belonging to the sphere of zoosemiosis, from a biosemiosic perspective human beings too communicate mostly through nonverbal signs (see Sebeok 1998, 2001). Moreover, voluntary communication is wholly subtended by endosemiosic processes such as those relative to the immunitary and neural systems.
A Socio-semiotic Analysis of Qat culture in Yemen
Authors:   Salem  Al-Baha University Yemen, Salem Nabil
Published: July 2021

Qat, Catha edulis has become synonymous with Yemen, as the phenomenon of Qat chewing in Yemen dates back hundreds of years in history. No social, cultural, or political gathering in the afternoon time can do without Qat. Afternoon time becomes the sign of Qat sessions and socialization. Despite Yemen's openness to other cultures and the recent revolution in all kinds of social media, Yemenis do not stop the habit of chewing Qat. The purpose of the present research work is to analyze 'Qat' as a linguistic sign consisting of a signifier and a signified to understand its various social, cultural, and political signifieds that give it the semiotic power to dominate all aspects of life in Yemen and to ground the coinage of many lexical items that are culturally specific to Qat culture and Yemeni dialects. The present paper uses semiotics as a research method in which it adopts Saussure's linguistic model of sign, signifier, and signified and Barthes' concepts of denotation and connotation. Semiotically, this paper shows that the Yemeni people are not addicted to Qat as a drug, as might be assumed by some foreigners who are not familiar with the sign system of Yemeni culture. The Yemeni people are addicted to Qat as a polysemous sign that is associated with values, norms, rituals, enjoyment, relationship, and socialization at the connotative level.

Published: July 2021

The aim of this study was to explore the possible molecular mechanisms of paeonol in preventing ventricular remodeling. The cell viability of neonatal rat cardiac fibroblasts was detected by the method of MTT. RT-PCR and Western blot were used to measure the expression of TGF-β1, type I collagen and type III collagen. After treating the cardiac fibroblasts with paeonol, the cell viability decreased (p<0.01), and the expression of TGF-β1, type I collagen and types III collagen was significantly reduced (p<0.01). Thus, paeonol can inhibit the proliferation of fibroblast cells induced by aldosterone. The molecular mechanism is related to the down-regulation of TGF-β1 and type I and III collagen gene expression.

Tarkastelu jaksottuu kolmeen ajanjaksoon, jotka liittyvät etenkin venäläisen rahapelijärjestelmän muutoksiin sääntelytasolla, ja suomalaisten rahapelitoimijoiden mahdollisuuksiin. Näitä ovat venäläisten rahapelimarkkinoiden kasvuaika 1990-luvulla, vuoden 2006 rahapeliuudistuksen rajoittama markkinaympäristö ja uusien markkinoiden synty sekä vuoden 2014 jälkeinen aika, johon on liittynyt niin ruplan romahtaminen kuin koronapandemian tuomat haasteet matkailulle

Finland and the Russian gambling market

Gambling operations in border regions are common internationally, but Finnish cross-border gambling offers have been scarce. This paper discusses how Finnish gambling operators have attempted to access the Russian market since the 1990s, based on previous literature and existing statistical information. The aim is to describe whether and how Finnish actors have exported gambling to Russia or Russians, and what kind of political and economic factors have influenced the commercial relationship. The analysis focuses on three periods determined by regulatory changes in Russian gambling and the related possibilities for the Finnish gambling offer. These are the growth period of the 1990s, the restrictive gambling law of 2006 and the new market environment, and the period starting from 2014 characterised by challenges to tourism and business following the financial crisis and the coronavirus pandemic.

Authors: Apriliana Nana
Published: July 2021

In the rapid development of religion-based schools in Indonesia, especially Islam, this study intended to determine the problems experienced by students, parents, and teachers in Islamic primary school (Madrasah Ibtidaiyah) during online learning due to the pandemic Covid-19. This was a descriptive study using the online survey method. The data was collected using online open-ended questionnaires to 136 participants of elementary school students, parents, and teachers. It was found that students preferred play to study, they were lack of discipline in learning and felt bored studying at home. Whereas, the entire phone's memory, unstable internet connection, and lack of budget for internet connection were the most obstacle factors faced by parents and teachers. The teachers also had unlimited working time. Parents were also challenging to explain the materials for their children, challenging to build students' motivation, difficult to divide the time between work and guide their children to study. Therefore, the researcher recommends (1) applying learning rules to discipline students learning activities during online learning, (2) consulting with teachers or find appropriate sources to explain difficult materials i.e. free access to online learning media provided by the Ministry of Education and Culture (MoEC) to enrich learning sources, (3) creating a comfortable learning atmosphere, trying to learn outdoor and interspersed with fun activities are essential methods to kill children boredom in online learning, and (4) equipping teachers with online learning skills i.e. the use of technology, software, and teaching online method in long term teacher education program (Pendidikan Profesi Guru/PPG) to improve teachers' teaching quality in online teaching.
Production of Methyl ester from Coconut Oil using Heterogeneous K/Al2O3 under Microwave Irradiation
Authors: Suryanto Andi , Kalsum Ummu , Qadariya Lailatul , Mahfud Mahfud
Published: July 2021

Methyl esters derived from coconut oil are very interesting to study because they contain free fatty acids with a medium carbon chain structure (C12-C14), so most methyl esters (70%) can be bio-kerosene and the rest can be biodiesel. The process of preparing methyl ester by reaction of Trans-esterification triglyceride generally using a homogeneous KOH catalyst but this process requires a long catalyst separation process through washing and drying process. The use of heterogeneous catalysts in the production of methyl esters can remove the washing and drying processes, but trans-esterification reactions with heterogeneous catalysts require severe conditions (high pressure and high temperature), whereas at low temperatures and atmospheric conditions, the methyl ester yield is relatively low. Using microwave-irradiated trans-esterification reactions with heterogeneous catalysts, it is expected to be much faster and can obtained higher yields. Therefore, in this study we prepare a heterogeneous catalyst K/Al2O3 using solution KOH that impregnated in catalyst support Al2O3, and catalyst obtained are caracterized by XRD, BET dan SEM. Our objective was to compare the yield of methyl esters obtained through the trans-esterification process of coconut oil assisted by microwave using a heterogeneous K / Al2O3 catalyst with yield obtained using a homogeneous KOH catalyst. Experimental equipment consists of a batch reactor placed in a microwave oven equipped with a condenser, agitator and temperature controller. The batch process was carried out at atmospheric pressure with variation of K/Al2O3 catalyst concentration (0.5, 1.0, 1.5, 2.0, 2.5%) and microwave power (100, 264 and 400 W). In general, the process of producing methyl esters by heterogeneous catalysts will get three layers, wherein the first layer is the product of methyl ester, the second layer is glycerol and the third layer is the catalyst. The experimental results show that the methyl ester yield increases with increasing of microwave power, catalyst concentration and reaction time. The results obtained with K /Al2O3 catalysts are generally slightly lower than those obtained using a homogeneous KOH catalyst. However, the yield of methyl esters obtained by the K / Al2O3 heterogeneous catalyst process are relatively easy to separate rather than using a homogeneous KOH catalyst.

Published: July 2021

Family Sport Clothing convection is Mr. Raharjo’s family business in textile industry which produces training pants, made of lotto fabric. The company only has one criterion in supplier selection process, and in this convection is the cost. In this convection, problems that usually occur in selecting the supplier of raw materials are the production process is delayed since the raw materials are not enough; the quality of the raw materials does not meet the company standards; and supplier that does not deliver on time. This study was conducted with the aim of identifying the criteria used in selecting supplier and determining the ranking or the best supplier priority. The researcher implemented AHP (Analytical Hierarchy Process) method by distributing questionnaires to the owners of convection, and TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) by measuring the shortest distance between positive ideal solutions and the longest distance with negative ideal solutions. The criteria were adopted from previous researches, and processed by using Pareto diagrams. Based on the results of calculations using Pareto diagram, the criteria used in this study are quality, cost, service, delivery, feasibility, and capacity. Based on the results of calculation using AHP method, the order of the most prioritized criteria is: quality (0.37), cost (0.29), capacity (0.13), feasibility (0.12), delivery process, (0.07,) and service (0.03). In addition, the priority order of the suppliers based on TOPSIS is: Libeng Kiantana (0.45), Yudi Hartono (0.23), Abdul Ghofur (0.23), Panorama Shop (0.06) and Indigenous Face Shop (0.02).

Knowledge sharing among employees has been identified as one of the factors that contribute to improved job performance. Thus, this study examines the relationship between engineer’s perceived enjoyment, perceived status and subjective norm on their intention towards knowledge sharing in public oil and gas firms in Iraq. The study selects 240 engineers from oil and gas companies in Iraq to participate in the research. A questionnaire designed in a Likert scale format was used for the data collection. The data were analysed using descriptive statistical analysis and Correlation analysis. The results of the analysis show that there is a positive relation between engineer’s perceived enjoyment, perceived status and subjective norm on their intention towards knowledge sharing in public oil and gas firms in Iraq. The paper makes some recommendations on how to increase engineers’ perceived enjoyment, perceived status and subjective norm and eventually increase intention towards knowledge sharing.

Sea urchins are considered the most important grazers in Mediterranean shallow sublittoral rocky reef ecosystems, but fish can also have an important role in overgrazing and the reduction of habitat complexity. In this study, the trophic behavior of fish was recorded when provided access to experimental surfaces with increased macroalgal biomass and associated benthic fauna, created by herbivore exclusion cages. After a sufficient period for substantial algal growth, the cages were removed and the activity of fish on these surfaces was recorded for 3 h by an automated photographic camera system. Control surfaces with no restriction on grazers were defined on similar substrates for comparison. To quantify the effects of fish feeding activity on macroalgal coverage, photographic samples were taken immediately after the opening of the cages and after each 3 h recording. The response of fish when the cages were removed was immediate and intense. Feeding activity by 13 different fish species was recorded in total, of which the most frequent were the omnivores Diplodus vulgaris, Coris julis and Thalassoma pavo, and to a lesser extent the herbivore Sarpa salpa. The coverage of erect algae was substantially decreased on the experimental surfaces due to fish feeding activity. The algae were either directly consumed by the fish or cut off when the fish were feeding on macroinvertebrates. We conclude that in addition to grazing by herbivores, fish of higher trophic levels can also significantly affect macroalgal assemblages and restrict the recovery of erect algae in overgrazed reefs where prey is scarce.
"Papeles" comprados: procedimientos no ortodoxos implementados por guatemaltecos para adquirir documentos mexicanos de identificación personal
Authors: Bedoya Luis
Published: July 2021

This article analyzes a series of extralegal procedures implemented by Guatemalans to acquire Mexican personal identification documents. The research focuses on the experiences of descendants of families who took refuge in Mexico during the 1980s and 1990s and returned to Guatemala between 1994 and 1996. These young people, born in Guatemala after their parents returned to their country of origin, employed the practice of buying Mexican birth certificates which were later used to enter Mexico legally. The fieldwork was carried out in two Guatemalan villages, as well as two Mexican ones, located in Cancun and Playa del Carmen. The main argument is that for them Mexican identification documents become a singular force that confers recognition and offers them the possibility to be incorporated into governmental logic which grants material benefits. Such forms of political imagination are related to the experiences of multiple documentation accumulated by older generations during their refuge period and are now encouraged by the Mexican State’s new border security strategy.

The objective. To systematize the clinical manifestations of skin lesions associated with COVID-19 and to propose the classification of these disorders. Materials and methods. The literature data describing skin lesions associated with COVID-19 and the results of observation of 31 patients with skin lesions and coronavirus infection were summarized. In the postcovid period patients with skin diseases were admitted to the hospital. They were divided into two groups: first – patients who did not suffer from skin diseases earlier; the second – patients with exacerbation of chronic dermatoses. All patients were examined by standard clinical and laboratory methods. Results. The proposed classification makes it possible to separately distinguish lesions caused precisely by COVID-19 and exacerbation of chronic dermatoses against the background of coronavirus infection, as well as as a result of the treatment of this disease (first of all, this consider to systemic corticosteroids, which are known to affect the course of psoriasis: cause the development of common forms that are resistant to other methods of therapy), which leads to their severe course. Photos of own observations are presented. This classification will improve the quality of diagnosis of COVID-19, especially in asymptomatic or low-symptomatic forms of the disease, and will also help prevent a number of complications associated with both the treatment of patients with coronavirus infection and the presence of concomitant diseases, in particular chronic dermatoses. Conclusions. The proposed classification, on the one hand, expands the possibilities of timely diagnosis of COVID-19, especially in asymptomatic or low-symptomatic forms of the disease, and also directs the doctor to the need to prevent a number of complications associated with both the treatment of patients and the presence of concomitant diseases, in particular chronic dermatoses.
The Riemann Hypothesis
Authors: Vega Frank
Published: July 2021

Robin criterion states that the Riemann Hypothesis is true if and only if the inequality $\sigma(n) < e^{\gamma } \times n \times \log \log n$ holds for all $n > 5040$, where $\sigma(n)$ is the sum-of-divisors function and $\gamma \approx 0.57721$ is the Euler-Mascheroni constant. This is known as the Robin inequality. We obtain a contradiction just assuming the smallest counterexample of the Robin inequality exists for some $n > 5040$. In this way, we prove that the Robin inequality is true for all $n > 5040$. Consequently, the Riemann Hypothesis is also true.
Assessing psychosis risk using quantitative markers of transcribed speech
Authors: Morgan Sarah
Published: July 2021

Behaviourally and cognitively, psychosis expresses itself by subtle alterations in language. Recent work has suggested that Natural Language Processing markers of transcribed speech might be powerful predictors of later psychosis (Mota et al 2017, Corcoran et al 2018). However, it remains unclear which NLP measures are most likely to be predictive, how different NLP measures relate to each other and how best to collect speech data from patients. In this talk, I will discuss our research tackling these questions, as well as the wider challenges of translating this type of approach to the clinic. Ultimately, computational markers of speech have the potential to transform healthcare of mental health conditions such as schizophrenia, since they are relatively easy to collect and could be measured longitudinally to quickly identify changes in patients' disease trajectories.

When dealing with predictive modeling on credit-granting, different types of attributes are used: Cadastral, Behavioral, Business / Proposal, Credit Bureaux, in addition to Public, Private or Subsidiaries Sources. The Postal Address Code (Código de Endereçamento Postal CEP in Portuguese) in Brazil, in particular, has a unique contribution capacity (uncorrelated with most other attributes in general) and reasonably good predictive power. CEP is frequently used by truncating its numeric representation, considering the first d digits, for example. In this report, a preliminary methodology is proposed, aiming to elaborate clustering sets of CEPs by considering the information of clients' defaults over a period of time. Additionally, we tested the number of clusters obtained using the Information Value criterion. Promising solutions are obtained using statistical and optimizing approaches. Other methodologies are suggested and could be complementary with the principal methodology proposed.
