Photocatalyst with multiple modification sites (MSs) exhibited better performance than single site in photocatalytic H2O2 evolution, while the corresponding reaction mechanism is more complicated. However, neither experiment nor density functional theory (DFT) based on ground state wavefunction cannot precisely confirm the role of each site in photocatalyst with multiple MSs. Here, we propose a universal method that flexibly combines experiments, DFT and time-dependent DFT (TDDFT) calculations to reveal the photocatalytic mechanism and active site of nitrogen deficiency g-C3N4 (NDCN) containing two MSs (bicoordinated nitrogen vacancy and cyano group). Characterization techniques and control experiments prove that generation of H2O2 on NDCN is a two-step single electron transfer process, and NDCN exhibits enhanced charge separation efficiency and higher selectivity for two-electron oxygen reduction. DFT-TDDFT calculations further indicate that nitrogen vacancy is the real catalytic site for activating O2, which promotes O2 adsorption and continuously formation of •O2−, thus inhibiting electron-hole recombination.

Published: October 2020

BackgroundAutism Spectrum Disorders (ASD) is a neurodevelopment disorder. The cerebellum has been reported to be one of the key regions involved in ASD. However, the associations between the cerebellum and clinical traits remain unclear. MethodsHere we performed Amplitude of Low Frequency Fluctuations (ALFF) analysis to detect the alterations of brain spontaneous activity in ASDs and explore the associations between spontaneous brain activity and clinical traits. ResultsCompared with normal controls, cerebellum crus 2 showed significantly weaker average ALFF values. Other regions such as left cerebellum 6, cerebellum vermis 4 5, putamen, SMA and thalamus showed increased mean ALFF values. In ASD patients with SRS total score T above 59, the mean ALFF values of cerebellum vermis 4 5 was significantly correlated with SRS total score T (r=0.175, P=0.031), SRS cognition score T (r=0.169, P=0.036) and SRS motivation score T (r=0.176, P=0.028).ConclusionsThese findings were not observed in other brain regions and in normal controls. Our study suggests a role of cerebellum in cognitive impairments in ASD and supports a mechanistic basis for the targeted treatment of ASD disorders.Trial registrationNot applicable.

Published: October 2020

Background: With enhanced rollout of anti-retroviral therapy (ART) following prevention of mother to child transmission (PMTCT) and the associated burden of opportunistic infections in developing countries, human immunodeficiency virus-immune reconstitution inflammatory syndrome (HIV-IRIS) may remain a public health area of major concern especially, in pregnancy. Ascertaining the association between maternal HIV infection and adverse maternal and birth related outcomes could be conflicted by the relationship between maternal-HIV- IRIS and the adverse pregnancy-fetal outcomes (APFOs) in HIV-infected mothers. We sought to estimate the incidence and determine possible predictors for adverse pregnancy-fetal outcomes with maternal-HIV-IRIS in ART naïve HIV infected pregnant women. Methodology: Subjects grouped in to IRIS exposed and non-IRIS exposed were followed from the end of first trimester for six and half months. Chi-square test was used to establish the association between the variables at p-value < 0.05. Regression analysis was performed to identify independent predictors of APFOs. Adjusted Relative Risk at 95% confidence interval was determined. Results: The IRIS exposed pregnant women, had a 26.47% adverse pregnancy-fetal outcomes cumulative incidence compared to 10.78% among IRIS non-exposed women. The APFO incidence rate estimate was 0.012 and 0.0045 per person’s week respectively. IRIS cases had 2.46 times the risk of experiencing an APFO compared to those who did not [OR=3; 95%CI: 1.4-6.4; P=.004], at bivariate analysis, not sustained at the multivariate analysis [AOR=1.6; 95%CI: 0.4-5.8; P = .508]. Multiple logistic regression dropped maternal HIV-IRIS and revealed; HIV-RNA viral load at baseline of above 50 copies/ml [AOR=2.7; 95%CI: 1.2-6.3; P=.017], Maternal placental syndrome(MPS) characterized by hypertensive event [AOR=0.1; 95%CI:0.0-1.0; P = .052] and mother’s general health during delivery [AOR= 4; 95%CI: 4.0:1.8-9.1;P=.001] as independent predictors of APFOs. Conclusion: There is a higher incidence of APFOs among maternal HIV-IRIS diagnosed pregnant women as compared to non-HIV maternal IRIS diagnosed pregnant women. In particular, MPS characterized by an hypertensive event, HIV-RNA viral load at baseline of above 50 copies/ml and mother’s general health during delivery are key predictors of an adverse pregnancy outcome. Interventions to reduce the associated risk predictors identified in this analysis should be studied for their effects on reducing APFOs.
Pregnancy outcomes of infertile women with co-existing endometriosis and adenomyosis after laparoscopic surgery: a long-term follow-up
Authors: Shi Jinghua , Dai Yi , Zhang Junji , Li Xiaoyan , Jia Shuangzhen , Leng Jinhua
Published: October 2020

Background: Adenomyosis and endometriosis are often co-existent. Laparoscopic surgery is one of the main methods to diagnose and treat these conditions. However, very few studies have been done that concentrate on the pregnancy outcomes of infertile women with both adenomyosis and endometriosis after laparoscopic surgery, as well as the relevant influential factors.Methods: This is a retrospective, cross-sectional study including infertile women diagnosed with endometriosis and adenomyosis. All patients had undergone laparoscopic surgery and were divided into two groups according to pregnancy outcomes. Demographic data, operation records, and pregnancy outcomes were collected.Results: Ninety-seven patients had live births, including 81 full-term and 16 preterm deliveries. The biochemical pregnancy, clinical pregnancy, and live birth rates were 80.87%, 67.4, and 55.11% respectively. One hundred thirty-five patients received IVF with 70 (51.85%) patients having live births. Age, size of endometrioma, and size of uterus were significantly lower in those who had a successful delivery. There was no statistical difference in symptoms except anemia (13.40% vs. 25.32%, p=0.044). The group that failed to have a live birth had a higher percentage of ovarian and peritoneal endometriosis (P<.05), while the distribution of deep infiltrating endometriosis and adenomyosis types were similar. Mean uterus diameter (OR: 0.636, 95% CI: 0.434-0.932, p = 0.020) and endometriosis fertility index (EFI) (OR:1.299, 95% CI: 1.101-1.531, p = 0.002) were significantly correlated with live births in the multivariate analysis.Conclusions: Endometriosis and adenomyosis have an adverse effect on fertility. IVF is an important technology improving pregnancy rate even after surgery. The size of the uterus and EFI were independent risk factors for pregnancy outcomes.

On March 2, 2020, the first Coronavirus Disease (COVID-19) case was reported in Jakarta, Indonesia. One and half month later (15/05/2020), the cumulative number of infection cases was 16496 with a total of 1076 mortalities. This study is aimed to investigate the possible role of weather in the early cases of COVID-19 incidence in six selected cities in Indonesia. Daily data of temperature and relative humidity from weather stations nearby each city were collected during the period 3 March - 30 April 2020, together with data of COVID-19 cases. Correlation tests and regression analysis were performed to examine the association of those two data series. In addition, we analysed the distribution of COVID-19 with respect to weather data to estimate the effective range of weather data supporting COVID-19 incidence. Our results reveal that weather data is generally associated with COVID-19 incidence. The daily average temperature (T-ave) and relative humidity (RH) presents significant positive and negative correlation with COVID-19 data, respectively. However, the correlation coefficients are weak with the strongest correlations found at 5 day lag time i.e. 0.37 (-0.41) for T-ave (RH). The regression analysis consistently confirmed this relation. The distribution analysis reveals that the majority of COVID-19 cases in Indonesia occurred in the daily temperature range of 25-31oC and relative humidity of 74-92%. Our findings suggest that COVID-19 incidence in Indonesia has a weak association with weather conditions. Therefore, non-meteorological factors seem to play a larger role and should be given greater consideration in preventing the spread of COVID-19.

BackgroundTo evaluate the utility of age and chest radiography(CXR) in triaging COVID-19 patients for hospitalization versus isolation in non-hospital facilities, we examined how age and CXR at diagnosis were associated with clinical needs from late-January to early-April. MethodsClinical status of all COVID-19 cases was monitored for national disease surveillance. Cases were isolated in hospitals until SARS-CoV-2 RNA was undetectable on PCR. Age and CXR results on admission were analysed for association with oxygen supplementation and mechanical ventilation, the outcomes of interest.ResultsTill 4 April 2020, there were 1,481 COVID-19 cases in Singapore. Overall, 11.4% required supplemental oxygen while 4.8% required mechanical ventilation and intensive care. The respective proportions increased to 40.9% and 16.5% for cases aged ≥70 years. As a predictor of subsequent mechanical ventilation, age had an area under the receiver operator characteristic curve(AUROC) of 0.772 (95%CI:0.699-0.845). A combined criterion of either an abnormal CXR or age≥55 years had a sensitivity of 86.7% and specificity of 58.0% for the same outcome. A similar performance was observed for predicting oxygen supplementation needs.ConclusionsAge and CXR at diagnosis may be valuable in excluding severe disease, allowing safe triage for isolation in non-hospital facilities.

Harvest Time and Postharvest Behavior of Six Japanese Nonastringent Persimmon Cultivars Grown under Mediterranean Conditions
Authors: Fathi-Najafabadi Ayoub , Besada Cristina , Gil Rebeca , Salvador Alejandra
Published: October 2020

Persimmon cultivation has significantly grown in the Mediterranean Region in recent years. The production concentrates mainly in three astringent cultivars: Kaki Tipo in Italy, Triumph in Israel, and Rojo Brillante in Spain. Therefore, the varietal range expansion is one of the current challenges for persimmon producers in this area. Moreover, the introduction of nonastringent persimmon cultivars is particularly interesting because they can be commercialized immediately after harvest without applying deastringency treatment before commercialization. This study evaluated the harvest period and the postharvest response of six Japanese nonastringent cultivars (Kanshu, Shinshu, Soshu, Suruga, Youhou, Izu). During two seasons, fruit from each cultivar were harvested at two maturity stages. Fruit quality (external color, firmness, and total soluble solids) was evaluated after harvest and after different commercial scenarios (domestic market: 7 days at 20 °C, market to European Union (EU): 5 days at 5 °C plus 5 days at 20 °C, and market to countries with cold-quarantine treatment requirements: 21 days at 0 °C plus 5 days at 20 °C). Cultivars Kanshu, Shinshu, Soshu, and Izu were identified as early cultivars, and Soshu was the earliest one, which reached commercial maturity at the beginning of September. These four cultivars showed good quality after simulating commercialization on domestic and EU markets. Cultivars Suruga and Youhou overlapped the current harvest window, but their low chilling injury sensitiveness is highlighted, so they are of special interest to be cold-stored at the end of the season to be commercialized in overseas markets.
Performance of Sweetpotato Varieties Grown Using Black Plastic Mulch in Pennsylvania
Authors: Duque Luis O.
Published: October 2020

Sweetpotato (Ipomoea batatas) production in Pennsylvania and the northeastern United States has been increasing steadily. The performance of eight commercially available sweetpotato varieties and two unreleased accessions grown on raised beds and covered with black plastic mulch in Pennsylvania was evaluated. All varieties and accessions were evaluated in 2 successive years (2018 and 2019) at Rock Springs, PA. There were statistically significant differences in total marketable yield (TMY), but not in all yield components in both years. ‘Orleans’, ‘Beauregard’, ‘Averre’, and ‘Covington’ consistently produced high marketable yields and suitable U.S No.1 grade storage roots. ‘Bonita’ (tan skin/white flesh) and ‘Carolina Ruby’ [red skin/orange flesh (OF)] produced consistent yields in both years (range, 330–430 bushels/acre; 50-lb bushel). NC413 [purple skin (PS)/purple flesh (PF)] produced the lowest yield in 2018 and was discarded for future trials. In 2019, NCP13-0030 (PS/PF) produced good yields and shapes comparable to OF varieties. Overall total yields (TYs) measured in this study compared satisfactorily with average nationwide yields, with several varieties producing more than 500 bushels/acre.

Powder samples of Zn1-xMnxO nanocrystal were synthesized at a temperature of 200 °C using solid phase method. Dopant concentrations of 0.005 ≤ x ≤ 0.5 were studied. Powder x-ray diffraction (PXRD) patterns of the samples were analyzed with a view of determining the onset of secondary phases, hence the solubility limit of the dopant. The solubility limit for Mn in ZnO samples synthesized at 200 °C is realized at x < 0.3. With a regular pattern in increment of the Mn concentration, there were variations observed in the trend of the relative intensity, 2θ position and d-spacing indicating uneven addition of Mn (thus Mn2+, Mn3+ or Mn4+).
Life-cycle costs approach for private piped water service delivery: a study in rural Viet Nam
Authors: Grant Melita , Foster Tim , Dinh Dao Van , Willetts Juliet , Davis Georgia
Published: October 2020

Sustaining rural water services in Viet Nam requires an improved understanding of the costs and relative opportunities, especially given the government's support for private sector involvement in expanding water schemes. In particular, the life-cycle costs associated with the delivery of safe and sustainable water services in rural Viet Nam, as indeed elsewhere, are not well known, potentially compromising their long-term sustainability. To address this gap, this study assessed the cost structures of 14 water schemes in Viet Nam managed by private enterprises. Results showed that both capital and operational expenditures varied widely across the schemes assessed, reflective of the diversity of the age and characteristics of the schemes studied. Twelve of the 14 schemes generated a cash profit in the most recent calendar year; however, when taking into account depreciation, as well as historical subsidies and connection fee payments, only four of the schemes were profitable based on a 20-year design life assumption. The study complements previous research demonstrating barriers to achieving universal access when relying on user-pays systems. The results provide a useful reference point to inform business planning for enterprises, as well as policy and support mechanisms important for securing sustainable rural water supply services.

Published: October 2020

Coronavirus pandemic in 2020 shock the entire world. Some countries with federal system have troubles, because the results of their functioning in the new conditions was inconsistent: some countries showed a low level of fatality from the coronavirus in general controlled the situation, but others had the highest incidence and in the background – the destabilization of the socio-economic and even political situation. The article analyzes the main trends of global development in the context of a pandemic, foreign and domestic experience of functioning of system of public authorities on federal, regional and local levels, measures to ensure the smooth operation of public authorities at all levels in a pandemic, as well as problems in the functioning of public authorities in the new conditions. This allows us to conclude that federal state system, on the one hand, has its advantages in countering these threats, including the possibility of a differentiated approach to different territories, well-established mechanisms of interaction between the levels of public power, and, on the other hand, it is characterized by a some types of risks, such as an imbalance of power, authority and resources in the federal system and a lag in making the necessary decision. It may be the reason of sharp decline in the pace of socio-economic development and the situation in the regions out of the control of the federal authorities. In the context of a pandemic, there are certain problems associated with insufficient coordination between levels of government, but they can be overcome through the use of various management mechanisms.
Consolidated Budgets of Russian Regions in the Context of the Crisis Provoked by the Global Pandemic
Authors: Lykova L. N.
Published: October 2020

In the first half of 2020, with a marked reduction in tax revenues, there was an increase in the total amount of revenues of the consolidated budgets of the subjects of the RF, which in most cases did not compensate for the rate of inflation. The growth of the total amount of revenue was provided by the outstripping growth of all types of Federal transfers to the regional budgets. The situation in different regions of the country varied significantly, and the most serious losses were incurred by the most economically developed regions. Moscow bear the burden of a significant part of the total revenue loss. The growth of expenditures of the consolidated budgets of the Russian regions was significantly faster than the growth of their revenues. Health and social policy funding has increased most significantly, supported in part by Federal transfers. With the total deficit of the consolidated budgets of the Russian regions, about half of the regions had a positive budget balance (partly of a technical nature) at the end of the half-year. At the same time, the growth rate of public debt is not yet critical.

The sanitary and epidemiological situation that developed at the beginning of this year due to the spread of a new coronavirus infection and the subsequent quarantine measures had a negative impact on the Russian economy. The government of the Russian Federation, the Central Bank, the Federal Assembly, and heads of state authorities responded to the pandemic as soon as possible and took measures to support the population, the sectors of the economy at risk, small and medium-sized businesses, and system-forming enterprises. Additional financial assistance was provided to families with children, citizens who lost their jobs, small and medium-sized businesses, and regional budgets. In addition, earned credit programs on concessionary terms In the article the basic state measures, which helped in difficult times of crisis to preserve the stability of the financial system and support demand of the population is presented indicators of the dynamics of business. However, the modern economy needs a broader set of measures that will allow businesses not only to overcome difficulties, but also to develop at a faster pace, since the negative effect on the Russian economy from a decrease in external demand and restrictive measures to combat the spread of coronavirus may have at the end of this 2020 year.
Retrospective Experience of Creating a Financial Security Cushion for Territorial Entities in Russia
Authors: Karavaeva I. V.
Published: October 2020

The analysis of the evolutionary development of local budgets revenue and spending at the turn of XIX and XX centuries allows us to abandon the point of view that has become familiar to Russian economic literature about the traditional and unconditional priority of the state’s economic interests over the economic and social interests of local territorial communities in Russia. The study of the process of formation of Zemstvo and city finances leads us to the conclusion that in retrospect there was a significant independence of territorial government bodies from the General system of state administration. The article presents the facts of the existence in Russia of a system of local taxes and property sources of income that ensure the financial independence of territorial entities. The article clearly shows that at the turn of XIX and XX centuries in Russia local administration structures were based on traditions similar to the principles of independence and self-sufficiency of local self-government systems widely used in modern practice in democratic countries.

ABSTRAKPendidikan Kewarganegaraan di Indonesia memiliki beberapa fungsi salah satunya sebagai pendidikan pendahuluan bela negara. Namun dalam praktiknya, proses pembelajaran Pendidikan Kewarganegaraan di perguruan tinggi masih belum menemukan formula yang sesuai dengan konsep pendidikan bela negara untuk warga negara sipil. Penelitian ini bermaksud untuk menjelaskan peranan Pendidikan Kewarganegaraan dalam konteks pendidikan pendahuluan bela negara di perguruan tinggi. Metode yang digunakan dengan pendekatan mix method dengan the dominant less dominant antara wawancara dan survey yang dilakukan kepada 400 peserta didik dan 8 dosen. Proses pengambilan data dilakukan pada peserta didik Universitas Pendidikan Indonesia yang berasal dari 10 (sepuluh) program studi yang berbeda. Hasil penelitian menunjukkan bahwa Pendidikan Kewarganegaraan di perguruan memiliki pengaruh terhadap nilai-nilai bela negara dengan kisaran yang berbeda. Hal tersebut dikuatkan dengan hasil wawancara bahwa Pendidikan Kewarganegaraan dapat meningkatkan kecintaan dan motivasi untuk membela negara namun masih dalam tataran pemikiran berbentuk pengetahuan belum pada tataran tindakan. Oleh sebab, praktik dalam pendidikan pendahuluan bela negara tergantung dari perilaku peserta didik itu sendiri. Hal tersebut memiliki implikasi bahwa Pendidikan Kewarganegaraan sebagai pendidikan pendahuluan bela negara untuk warga negara sipil syarat nilai tanpa makna yang tidak berpengaruh terhadap perilaku warga negara sipil secara aktual karena masih berada pada tataran konsep dan pengetahuan peserta didik semata. ABSTRACTCivic Education in Indonesia has several goals, one of which is as primary education for the country's defense. Nevertheless, in practice, the Civic Education learning process in tertiary institutions has not yet found a formula that is in line with the concept of state defense education for civilians. This study intends to explain the role of Civic Education in the context of primary education in state defense in tertiary institutions. The mixed-method approach method with the dominant less dominant between interviews and surveys conducted to 400 students and eight lecturers. The data collection process was carried out on the students of Universitas Pendidikan Indonesia, who came from 10 (ten) different study programs. The study results illustrate that Civic Education in universities influences the values of defending the country with different ranges. The interview results confirmed that Civic Education can increase the love and motivation to defend the country but still at the level of thought in the form of knowledge, not at the level of action. Therefore, practice in primary education in state defense depends on the behavior of the students themselves. It implies that Civic Education as primary education for civilians' defense is a condition without meaning that does not affect civilians' actual behavior because it is still at the students' concepts and knowledge only.

Penelitian ini mengangkat permasalahan Sungai Citarum yang keadaannya sangat memprihatinkan walaupun pemerintah daerah telah berupaya menanganinya dengan berbagai program dan dengan biaya yang sangat besar.  Ecological citizenship merupakan gerakan sebagai upaya mengubah perilaku masyarakat agar sadar lingkungan. Civic responsibility adalah kesadaran akan hak dan kewajiban sebagai warga negara yang bertanggung jawab. Tujuan penelitian adalah menganalisis program agar dapat mengubah mindset masyarakat mempunyai kesadaran untuk mencintai lingkungan. Metode penelitian menggunakan pendekatan kualitatif dengan observasi, dan wawancara. Hasil penelitian masyarakat masih belum memiliki kesadaran untuk membantu program pemerintah daerah, hal ini disebabkan karena faktor pendidikan, status sosial dan ekonomi. Cara yang tepat untuk mempromosikan ecological citizenship dan civic responsibility adalah edukasi tingkat sekolah menengah untuk menghindari krisis lingkungan, ekonomi, dan budaya di masa depan dengan menambahkan Kurikulum Kewarganegaraan. Komunikasi aktif dari pemerintah daerah kepada masyarakat terbangun kesadaran untuk ikut membangun lingkungan. ABSTRACTThis research about the Citarum River problem is in deplorable condition even though the local government has tried to solve it with various programs and at a very high cost. Ecological citizenship is a movement to change people's behavior so that they are environmentally aware. Civic responsibility is an awareness of the rights and obligations of the citizen. The research objective is to analyze the program to change the mindset of having the awareness to love the environment. The research method used a qualitative approach with observation and interviews. The results of the community research still do not have the awareness to help local government programs. It is due to factors of education, social, and economic status. An appropriate way to promote ecological citizenship and civic responsibility is secondary school level education to avoid future environmental, economic, and cultural crises by adding a citizenship curriculum in school. Citizen awareness can build from a good partnership between government and society

Estado del arte en el desarrollo de aplicaciones web basado en ingeniería dirigida por modelos.
Authors: Cabrera Mondeja Alexis , Gómez Baryolo Oiner
Published: October 2020

Un enfoque que ha tomado auge en los últimos años es el uso de técnicas de inegeniería dirigida por modelos (MDE, Model Driven Engineering) para la actualización de software, éstas técnicas no se usan solamente para crear nuevos sistemas, sino también para modernizar o evolucionar el software existente. Un enfoque muy utilizado con este fin es la ingeniería web dirigida por modelos (MDWE, Model Driven Web Engineering) que permite aplicar los principios de MDE en el desarrollo de aplicaciones web. A pesar de que algunos enfoques ya usan MDE para el desarrollo de aplicaciones web, todavía falta mucho por avanzar. Existen muchas limitaciones aún, ya que muchas propuestas están atadas a tecnologías y estilos arquitectónicos específicos, limitando la creación parametrizable de aplicaciones usando tecnologías diferentes, generalemente solo crean aplicaciones cliente-servidor y usan tecnologías específicas como PHP, JSP, Python, etc. Esto limita la generación de aplicaciones a partir de modelos, así como la movilidad de las mismas. El presente artículo propone hacer un estudio de los enfoques más usados en la ingeniería dirigida por modelos, profundizando en aquellos que se centran en el desarrollo de aplicaciones web.

Published: October 2020

El sector energético es uno de los que más emisiones de gases de efecto invernadero (GEI) genera debido a la quema de combustibles fósiles, razón por la cual debe optar por medidas que le permitan controlar sus emisiones. En este sentido, el objetivo de esta investigación es determinar la eficiencia de 20 países desarrollados en el control del uso de combustibles fósiles para generar energía utilizando como herramienta el análisis envolvente de datos (DEA) desde dos modelos: CCR y BBC. El estudio se realizó con el programa computacional MATLAB®. Para ello se usó la data del banco mundial para cuatro indicadores desde 1997 hasta 2012, y se formaron cuatro periodos de cuatro años cada uno. De los indicadores seleccionados, dos se tomaron como entradas y dos como salidas. Los resultados muestran que Suiza y Suecia se ubicaron sobre la frontera eficiente en todos los periodos considerados, demostrando un correcto uso de los recursos para controlar las emisiones de GEI en el sector energía. Por otro lado, el método BCC al ser menos restrictivo que el CCR permite mejorar las eficiencias relativas de los países en los todos los periodos considerados.

El objetivo general de la investigación que se perseguía era determinar el impacto del ciclo económico en el sector de la construcción en Ecuador durante el periodo 2007- 2015. Para poder hacerlo se utilizó herramientas metodológicas carácter cuantitativo para relacionar las variables que corresponden al Producto Interno Bruto y al sector de la construcción. Los resultados indican que durante el periodo 2007-2015 la relación entre las variables ha sido positivo pues dada la expansión que ha tenido la economía, así como los periodos de desaceleración de la misma este nunca dejó de crecer, es decir existe una relación directamente proporcional entre ambos, cuando crece el uno crece el otro, y este es un síntoma de recuperación o recesión en la economía. Debe hacerse la puntualización de que el más grande inversionista y constructor del Ecuador es el Estado y que esto representa obras de infraestructura, viabilidad, represas, vivienda entre otras, Se sugiere que los fondos provenientes de los impuestos y su eficiencia en la recaudación se sigan sumando a la Inversión y que el endeudamiento externo sea racional además del fomento de las exportaciones tradicionales y no tradicionales.

La modelación matemática tiene como objetivo fundamental reproducir con la mayor exactitud posible el comportamiento real del sistema físico que representa, es la base que se utiliza en el cálculo hidráulico para simular diferentes estados que se producen en la red de distribución de agua sin tener que llegar a experimentarlos físicamente. El proceso de elaborar un modelo matemático para una red de distribución de agua presupone recopilar toda la información posible acerca de su estructura y funcionamiento y tratarla posteriormente para que pueda ser asimilada por los programas de análisis correspondientes. El modelo matemático permite calcular todas las variables que caracterizan su comportamiento, al tener en cuenta el conjunto de líneas y nodos que representan a las tuberías, las bombas y estaciones de bombeo, las válvulas reguladoras y las automáticas, los depósitos y embalses, y los puntos de consumo o inyección que forma la red. La formulación matemática es aplicada a redes ramificadas, malladas y mixtas, al emplear el Método del Gradiente para realizar el cálculo del modelo hidráulico. El caso de estudio presentado muestra la diversidad de criterios a tener en cuenta durante el diseño de una red de abastecimiento, los cuales deben considerarse en el modelo matemático.

En la última década a nivel mundial el reconocimiento social a la gastronomía autóctona de los pueblos indígenas ha alcanzado crecientes niveles, por su gran aporte al valor competitivo de la oferta turística, convirtiéndose en muchos casos el actor principal del descubrimiento de nuevos placeres sensoriales y experiencias culinarias, y eje aglutinador de varias modalidades turísticas. El presente trabajo aborda la restauración de la comida típica amazónica, su incidencia en los turistas y el desarrollo de una gestión, para lo cual se inició con el diagnóstico de los seis (6) restaurantes catastrados como turísticos, mediante la técnica observación directa y participativa con cuatro (4) instrumentos denominados listas de chequeo, que previamente a su aplicación fueron validados usando los métodos DELPHI y ANOCHI. Esto para los procesos de elaboración culinaria y servicio gastronómico, sub-proceso de prestación del servicio, y oferta gastronómica y carta menú, considerados como claves en la actividad. Resultados que mostraron los puntos fuertes y débiles existentes, y que se analizaron a través de una matriz DAFO de impactos cruzados que posicionó el objeto de estudio en el cuadrante III adaptativo o de reorientación. Por lo que, se determinaron 8 estrategias compuestas por 15 acciones y 12 actividades para mejorar la calidad del servicio, con miras a fortalecer la modalidad de turismo gastronómico sostenible.

Xenofobia y racismo en contra de los emigrantes representados en la cuentística ecuatoriana
Authors: Salazar Estrada Yovany
Published: October 2020

El artículo se propone analizar las expresiones de xenofobia y racismo en contra de los ecuatorianos que han emigrado con rumbo hacia Estados Unidos y España, conforme se representa en los cuentos publicados durante las últimas cuatro décadas. En el desarrollo del estudio se fundamenta, ejemplifica y analiza la recreación literaria de dos aspectos problemáticos que golpean a los protagonistas de la emigración: el tratamiento discriminatorio que reciben al ser tratados como los “otros” en los países de destino; y, algunas manifestaciones de xenofobia y racismo, en contra de los ecuatorianos mientras permanecen en el extranjero.

La formación de competencias investigativas en los estudiantes del Instituto Tecnológico de Formación Profesional, Administrativa y Comercial se concibe implícitamente en el Plan de estudio con actividades interdisciplinarias y transdisciplinarias que se llevan a cabo por los docentes durante el paso de los estudiantes por la institución como parte del proceso enseñanza –aprendizaje. En conjunto con esto se desarrollan actividades como las Jornadas Científicas Estudiantiles que han sido un elemento importante en la motivación de los estudiantes para investigar sobre diversas temáticas. En el presente trabajo se hace una contextualización de la formación de competencias investigativas en los estudiantes del instituto a través del análisis de la participación de los mismos en las cinco Jornadas Científicas Estudiantiles que se han desarrollado hasta la actualidad.

La presente investigación determina si el crédito otorgado por los Bancos Privados del Ecuador influyó de alguna forma sobre el sector de comercialización y exportación de camarón en el Ecuador para el periodo 2005-2016. Para comprobar dicha relación se realizó una recolección de datos en páginas oficiales como la Súper Intendencia de Bancos, Trade Map y Banco Central del Ecuador los cuales sirvieron de base para la realización de varios test econométricos como Modelos De Vectores Autorregresivos, Prueba de Causalidad de Granger, Prueba de Raiz Unitaria, entre otros. Obteniendo como resultado la inexistente relación entre los montos de créditos otorgados y los niveles de exportación para el periodo 2005-2016, esto significa que el papel de la banca dentro del sector exportador de camarón no juega un rol importante sino por el contrario el sector exportador es totalmente independiente con respecto a la banca.
innovación en el pensamiento económico. Un debate abierto.
Authors: García Leonard Yureidys , Sorhegui Ortega Rafael Antonio
Published: October 2020

La innovación es considerada paradigma de la competitividad de las naciones y por ende influye en el desarrollo de los países, razones por las cuales se convierte en una de las temáticas más estudiada y que preocupa a los gobiernos en el trazado de sus políticas industriales. Si bien es cierto que con el desarrollo de la escuela evolucionista se comienza a formalizar una teoría independiente a los modelos de crecimiento económico acerca del desarrollo tecnológico, este estuvo presente en el pensamiento económico. Los aportes de las diferentes escuelas sentaron pautas acerca de su concepción como un proceso: social, inclusivo y sostenible, no obstante a su desarrollo conceptual y a la proliferación de estudios empíricos que devienen en marcos normativos, no se puede concluir que se está en presencia de un concepto acabado de la innovación, aún en el debate científico quedan aristas por explotar en cuanto a la inclusión y al desarrollo de capacidades científicas y de innovación en economías en vías de desarrollo, donde la fortaleza de los sistemas de innovación constituyen un reto. El artículo que se presenta persigue analizar la evolución del concepto de innovación a través de los aportes de las escuelas del pensamiento económico, de modo que permita delimitar las brechas que existen en su metodología de estudio y que limitan el despunte de economías menos desarrolladas en tal sentido.
Crowdfunding: una revisión de la literatura
Authors: Sánchez Riofrío Angélica María , Palma Reyes Connie Pamela
Published: October 2020

El crowdfunding es una herramienta de financiamiento que brinda apoyo económico a aquellas personas que desean convertir un proyecto en realidad. Este instrumento de financiamiento busca ser un medio para la creación de nuevos negocios y para el desarrollo de los mismos. A pesar de los beneficios que otorga esta herramienta, en Ecuador es poco conocido este término. Debido a esta problemática se ha realizado una investigación exploratoria de la literatura aplicando herramientas cualitativas. El objetivo del trabajo es realizar una investigación exploratoria de la literatura relacionada con esta temática, para reconocer las contribuciones teóricas desarrolladas y las tendencias actuales de su investigación. Esta revisión cuenta con una metodología basada en tres criterios: el número de veces que los artículos científicos han sido citados, palabras claves y la indexación de las revistas consultadas. Se concluye que los jóvenes universitarios deben recibir por parte de la academia la motivación necesaria del tema. Por el lado empresarial y gubernamental deben trabajar para garantizar el bienestar de todos los miembros del crowdfunding. Para terminar el artículo, se invita a otros investigadores a seguir evaluando la información existente sobre las diversas plataformas de crowdfunding que se desenvuelven en la sociedad ecuatoriana.
