A Systematic Literature Review of Concepts and Factors Related to Pro-Environmental Consumer Behaviour in Relation to Waste Management Through an Interdisciplinary Approach
Authors: Concari Alessandro , Kok Gerjo , Martens Pim
Published: June 2020

Although there has been a steady increase in the number of studies on consumer behaviour in relation to sustainable development, there is limited focus on the product disposal phase. This systematic literature review intends to: (1) clarify how concepts related to pro-environmental consumer behaviour are understood and analysed in the academic literature on waste management; (2) discover any interplay between pro-environmental consumer behaviour and generic consumer behaviour, and the conditions and factors that favour it. A typical systematic literature review methodology was applied to the papers available on Web of Science, Science Direct and EBSCO (Elton Bryson Stephens Company) host between 1975 and 2019, leading to the selection of 699 final papers. The findings reveal that: (1) Although scholars tend to create a variety of pro-environmental consumer behaviour models depending on their specific field of inquiry, all approaches can be traced back to a limited number of reference theories; (2) The overall level of interplay between pro-environmental consumer behaviour and generic consumer behaviour is limited, nevertheless a favourable context or a supportive institutional-legal framework can significantly influence it; (3) A plethora of conditions and factors favour this type of interplay, involving social psychology, laws, economics, institutions and more; (4) Several critical issues appear in the analysed papers, especially some scholars’ assumptions to be able to identify all key factors. It follows the need for a more interdisciplinary approach, a deeper analysis of the effectiveness of the intervention measures at the governmental and institutional level, and a clear classification of factors and conditions (as proposed by this review).
Development and Predictive Validity of the Computational Thinking Disposition Questionnaire
Authors: Jong Morris Siu-Yung , Geng Jie , Chai Ching Sing , Lin Pei-Yi
Published: June 2020

Providing humans with quality education is regarded as one of the core pillars supporting the sustainable development of the world. The idea of computational thinking (CT) brings an innovative inspiration for people to adapt to our intelligent, changing society. It has been globally viewed as crucial that 21st-century learners should acquire the necessary skills to solve real-world problems effectively and efficiently. Recent studies have revealed that the nurture of CT should not only focus on thinking skills, but also on dispositions. Fostering students’ CT dispositions requires the cultivation of their confidence and persistence in dealing with complex problems. However, most of the existing measurement methods related to CT pivot on gauging thinking skills rather than dispositions. The framework of the CT disposition measurement model proposed in this paper was developed based on three theoretical features of thinking dispositions: Inclination, capability, and sensitivity. A two-phase analysis was conducted in this study. With the participation of 640 Grade 5 students in Hong Kong, a three-dimensional construct of the measurement model was extracted via exploratory factor analysis (16 items). The measurement model was further validated with another group of 904 Grade 5 students by confirmative factor analysis and structural equation modeling. The results align with the theoretical foundation of thinking dispositions. In addition, a CT knowledge test was introduced to explore the influences between students’ CT dispositions and their CT knowledge understanding.
The Sustainable Development Goals in Scientific Literature: A Bibliometric Overview at the Meta-Level
Authors: Meschede Christine
Published: June 2020

In 2015, the UN adopted the Sustainable Development Goals (SDGs), addressing social, environmental, and economic targets. Global partnerships, transnational, and interdisciplinary research are essential for achieving progress towards the SDGs. This study analyzes 4593 research articles at the meta-level, explicitly referring to the SDGs. This a comparably small amount of research items directly addressing the goals. However, comparisons with existing approaches using different queries are possible. Research that links to the SDGs through its title, keywords, or abstract facilitates knowledge sharing on the goals as it is easier to identify relevant work. Using scientometric means, we assessed the corresponding sources, research areas, affiliated countries, thematic foci, and the availability of funding acknowledgments. The results are useful for identifying research gaps and potential collaboration possibilities. The outcomes suggest that most research referring to the SDGs comes from the research areas Life Sciences & Biomedicine and Social Sciences. The most predominant SDG among the analyzed research articles is SDG 3 (“good health and well-being”). A relatively high share of open access articles contributes to the idea of knowledge sharing for the SDGs. Nearly 37% of all articles count as international publications, i.e., as being co-authored by authors from affiliations of multiple countries.

Published: June 2020

Gifted students are important for the development of knowledgeable societies. The present study examined Mexican elementary-school teachers’ knowledge about gifted students, specifically on screening criteria, educational strategies, and their social value. The relationships between teachers’ knowledge, teaching experience, and training in gifted education was analysed. A total of 1002 teachers (M age = 37.5, SD = 9.6 years old) from the 33 states of Mexico, 365 men and 510 females with 13.5 years of teaching experience, of whom 32% were trained in gifted education, completed an anonymous questionnaire. K-means cluster analysis revealed two clusters. Cluster 1 comprised teachers (61.2%) with poor knowledge, while Cluster 2 included teachers (38.8%) with basic knowledge and more teaching experience and training. Overall, the findings had implications for teachers’ training and educational policy.
Concrete Early-Age Crack Closing by Autogenous Healing
Authors: Roig-Flores Marta , Serna Pedro
Published: June 2020

Autogenous healing is mainly produced by continuing hydration or carbonation. The aim of this research is to quantify the crack closing produced by autogenous healing for early-age concrete. This healing was evaluated for two crack size levels, 0.1 mm and 0.4 mm, under three healing conditions: water immersion, a humidity chamber, and wet/dry cycles. Crack closing was evaluated after 7, 14, 28 and 42 days under healing conditions. The internal status of the cracks was verified visually and using phenolphthalein. The results show that specimens stored in the humidity chamber did not experience healing, while specimens under wet/dry cycles and water immersion achieved the complete closing of small-sized cracks (under 0.15 mm). Autogenous healing showed higher speed under wet/dry cycles but higher final efficiency under water immersion. However, the inspection of the interior of the specimens showed that self-closing occurred mostly on the surface, and carbonation in the crack faces was only noticed very near the specimen’s surface. Additionally, this study proposes a preliminary strategy to model autogenous healing in concrete in terms of crack closing.
Multi-Criteria Evaluation of Best Available Treatment Technology for Waste Lead-Acid Battery: The Case of China
Authors: Wang Wei , He Yi , Zhang Deyuan , Wu Yufeng , Pan Dean
Published: June 2020

Improper waste lead-acid battery (LAB) disposal not only damages the environment, but also leads to potential safety hazards. Given that waste best available treatment technology (BATT) plays a major role in environmental protection, pertinent research has largely focused on evaluating typical recycling technologies and recommending the BATT for waste LABs. First the evaluation indicators were selected based on the analysis of main factors affecting the pollution control of waste LAB treatment. The relative weights of each indicator were determined via the Delphi-attribute hierarchy model (AHM) in the second step. To determine the BATT, the attributive mathematics theory was adopted to calculate the attribute measure of single and multiple indices. Then, five recycling technologies commonly used in the secondary lead industry were estimated using the proposed evaluation system, and the feasibility of the recommended BATT was preliminarily verified. The results indicated that mixed smelting technology (MST), pre-desulfurization and multi-chamber smelting technology (PD-MCST), and direct smelting technology (DST) were found to perform well and were therefore deemed optimal for waste LAB disposal at this stage. The validation study showed that the DST can meet the requirements of pollution control, which is consistent with the evaluation results.
Participatory Research with Fishers to Improve Knowledge on Small-Scale Fisheries in Tropical Rivers
Authors: Silvano Renato Azevedo Matias , Hallwass Gustavo
Published: June 2020

Freshwater small-scale fisheries sustain millions of livelihoods worldwide, but a lack of monitoring makes it difficult to check the sustainability of these fisheries. We aim to compare and describe participatory research methods used in studies with fishers in the Tapajos River, a poorly known tropical river in the Brazilian Amazon. We address three interview approaches, two ways to do fisheries monitoring and two approaches for georeferenced mapping based on fishers’ knowledge, which can provide data about at least 16 topics related to fisheries. We highlight major advantages and shortcomings of these methods and illustrate their potential with examples of results on fisheries and fish biology of Peacock bass (Cichla spp. tucunaré in Brazil), an important commercial fish in the Brazilian Amazon. The interviews, participatory monitoring and mapping revealed which fish are more valued by local communities, how fish abundance and sizes varied over time, when fish are more often caught and show reproductive activity, and which sites or habitats fish need to reproduce. In addition to providing useful data from many sites in a cost-effective way, participatory methods can bring the additional benefit of including local stakeholders in the monitoring, management, and research activities.
OFDI Impact on Private Investment in the Gulf Economies
Authors: Shah Syed Hasanat , Ameer Waqar , Delpachitra Sarath
Published: June 2020

Gulf Cooperation Council (GCC) countries are highly dependent on hydrocarbons, which puts them at great risk to maintain stability in the long run. GCC countries need private investment to reduce their reliance on state and diversify their economies apart from hydrocarbon. The role of private investment is crucial to economic stability and development. Literature suggests that outward foreign direct investment (OFDI) can play a vital role in promoting private investment. Therefore, using feasible generalized least squares (FGLS) and panel corrected standard error (PCSE) techniques, we checked the impact of the GCC countries OFDI on private investment and found that OFDI significantly complement private investment in the GCC countries. The complementary impact of OFDI on private investment in the GCC countries can be used as a tool to promote private investment, diversify their economies and hedge against the pitfalls of addiction to the hydrocarbon.

Published: June 2020

The vast transformation the circular economy that will occur in the upcoming years inevitably will change the EU panorama, designing new scenarios from an economical-social-environmental perspective. To best build a circular economy, it is necessary innovative policy-planning with a holistic and systemic perspective that fosters a cohesive and smooth transition to circular business models. This paper explores the impacts of circular economy policy design processes driven by a systemic design and how this expertise could ease innovative and effective paths for policy-planning on a circular transition in EU regions. This examination of systemic design features recent approaches to design as a discipline addressing complex problems, and the literature review on systems and design thinking for sustainable development, and policy design, focusing on existing barriers to circular economy. The discussion is narrowed to the specific case study in which the systemic design methodology is applied to provide a path for five European regions towards the CE: the Interreg Europe RETRACE (A Systemic Approach for Regions Transitioning towards a Circular Economy) project. Including an in-depth examination of how systemic design can address current barriers for a circular transition within an effect in the short, medium, and long-term policy horizon in the transition of the European regions towards the circular economy.
Revenue Sharing of a TOT Project in China Based on Modified Shapley Value
Authors: Du Yanhua , Fang Jun , Zhang Jingxiao , Hu Jun
Published: June 2020

In recent years, China’s government has encouraged the adoption of the TOT (Transfer-Operate-Transfer) model to realize the marketization of China’s public service stock projects. The TOT model is a cooperation mechanism through sharing investment, revenue and risks between the government and private partner. Therefore, a fair and reasonable revenue sharing method (RSM) is the key to the success of the TOT project. This paper aims to provide a fair and reasonable RSM based on a modified Shapley value with a triangular symmetric fuzzy structure element, which has better motivation, flexibility, forecasting function and dynamic precise distribution function. According to the factors that affect revenue sharing, the Shapley value is improved with initial correction coefficient composed of investment ratio, risk-sharing ratio, execution degree, and fuzzy payment to achieve fairness and reasonableness. The methodology is illustrated by a case study of a TOT project selected from Laohekou city of Hubei province, China. The results testify that the revenue-sharing ratios of participants is positively correlated with the initial correction coefficient, which make the RSM more motivating; and the Shapley value with fuzzy payment by using triangular symmetric fuzzy element function make the RSM more flexible, and it has both forecasting function and precise dynamic distribution function under project revenue uncertainty.

Published: June 2020

This study aims at achieving the generation laws of the iconic gas compositions produced during the process of the cotton smoldering. A mini tube furnace was used to heat a long-staple cotton sample from Xinjiang, China, and a gas chromatography-mass spectrometer (GC/MS) was applied to analyze the produced organic and inorganic gas composition at different low temperatures ranging from 95 °C to 185 °C. Besides, a thermogravimetric experiment under air atmosphere was done in order to verify the correctness of the inferences. The pathways of product generation by heating cotton were set forth, including the depolymerization of the cotton cellulose, the sequential generation of coke, low molecular weight products, long chain carboxylic acids, levoglucosenone, and acetone at 125 °C, and the generation of hydrogen at 95 °C, carbon dioxide, carbon monoxide at 145 °C, and methane during the heating process. The results showed that the alkanes, furans, alkenes, aldehydes, hydrazines, and acids could not be regarded as the iconic gas compositions because of their little proportion, the joint detection of the methane and hydrogen could be used to predicate the smoldering, and the acetone and carbon monoxide could be used to confirm the smoldering stage. The results of the thermogravimetric experiment are consistent with theoretical analysis, indicating that analyses are reliable. This work will provide significant practice foundation for the early warning and prevention of cotton fires.

Published: June 2020

Antibodies play a central role in host immunity by directly inactivating or recognizing an invading pathogen to enhance different immune responses to combat the invader. However, the cellular responses of pathogens to the presence of antibodies are not well-characterized. Here, we used different mass spectrometry techniques to study the cellular responses of the pathogenic fungus Histoplasma capsulatum to monoclonal antibodies (mAb) against HSP60, the surface protein involved in infection. A proteomic analysis of H. capsulatum yeast cells revealed that mAb binding regulates a variety of metabolic and signaling pathways, including fatty acid metabolism, sterol metabolism, MAPK signaling and ubiquitin-mediated proteolysis. The regulation of the fatty acid metabolism was accompanied by increases in the level of polyunsaturated fatty acids, which further augmented the degree of unsaturated lipids in H. capsulatum’s membranes and energy storage lipids, such as triacylglycerols, phosphatidylcholines, phosphatidylethanolamines and phosphatidylinositols. MAb treatment also regulated sterol metabolism by increasing the levels of cholesterol and ergosterol in the cells. We also showed that global changes in the lipid profiles resulted in an increased susceptibility of H. capsulatum to the ergosterol-targeting drug amphotericin B. Overall, our data showed that mAb induction of global changes in the composition of H. capsulatum membranes can potentially impact antifungal treatment during histoplasmosis.

Published: June 2020

Background

Demand for GP services in the Republic of Ireland (RoI) is increasing, and the resultant escalation in workload demands is an issue of growing concern. Accordingly, the accurate measurement and description of GP workload is essential to inform future healthcare planning.

Aim

To provide a real-time measurement of GP workload with respect to hours worked and of proportional time expenditure on typical workload activities.

Design and setting

A prospective study among GPs in the RoI that took place from January 2019 to March 2019.

Method

Participants were invited to enrol in the study by direct email invitation and via notifications posted within GP-specific monthly journals; online forums; and a social media platform. Participants used a time-management software program to self-record workload activity in real time over 6 weeks.

Results

In total, 123 GPs were included for final analyses with a total of 8930 hours of activity recorded. The mean duration of a two-session day (excluding break-time) was 9.9 hours (95% confidence interval [CI] = 9.7 to 10.0; interquartile range [IQR] 7.9 to 13.9). Of this time, 64% was spent on clinical consultations. In total, 25.4% of activity was recorded outside the hours of 9.00 am and 5.00 pm. An average of 12.4 face-to-face consultations were completed per session of activity. The mean duration of a 10-session week was greatest for the partner (50.8 hours; 95% CI = 49.8 to 51.9) and >55-year-old (50.8 hours; 95% CI = 49.3 to 52.2) demographics, relative to their respective colleagues.

Conclusion

To the authors’ knowledge, this is the first study to provide an objective, accurate, and granular real-time measurement of GP workload in the RoI, demonstrating the significant volume and variety of work undertaken by GPs in the RoI.

Published: June 2020

ways of production of ceramic materials with use as the plasticizing additive of the sulphitic and alcohol bards (SAB), the calcium citrate filtrate (CCF) which is liquid withdrawal of production of citric acid in the microbiological way are known. However introduction to raw mix of CoB reduces forming humidity and fall of the formed products insufficiently, and an essential lack of FTsK is the low durability of products on compression with a big volume mass of samples.

In work the possibility of use as the plasticizing additive to a clay lot of withdrawal of the spirit industry – melasses bards is investigated. As a part of molasses the remains of amino acids and other organic substances which have the plasticizing effect on clay materials contain. On the example of natural clays of three various fields the plasticizing action melasses bards is proved, and the number of plasticity of the studied clays increases in direct ratio to increase in additive melassny bards in clay raw mix. It is shown that introduction to raw mix melasses bards leads to improvement of appearance of pottery, decrease in jointing, increase in durability for Veselovsky clay for 7%, for the Oryol clay for 67%, for Bessonovskaya – for 23%.

Research of the received ceramic samples on frost resistance according to requirements of GOST bards unlike the products which aren’t containing additive bards showed high frost resistance of products with additive melass. Also lowered decrease in durability and loss of mass of the samples containing additive melassny bards is noted

L'auteur donne une description abrégée d'une étude sur des systèmes d'équations différentielles non linéaires avec conditions aux limites également non linéaires. Basée sur la méthode de Newton généralisée, une procédure iterative à convergence quadratique est développée. Le fait que cette approche a un sens pratique est illustré au moyen d'un exemple numérique. Ensuite, des critères de convergence sont établis pour l'algorithme en question en utilisant une version modifiée du théorème de Newton-Kantorovic. Une application à ce même exemple numérique résulte en des approximations dont l'erreur est bien bornée.
Mystical Jerusalems
Authors: Stroumsa Guy S.
Published: June 2020

Between memory and imagination, the image of Jerusalem in the Western mind is deeply informed by the ambivalence of the city in Christian consciousness. The destruction of the Temple soon came to be perceived as a devine punishment visited upon the city for the killing of Christ. Parallel to the negative perception of Jerusalem, however, early Christian texts and traditions reflect the interplay of different conceptions of the city where Christianity was born : from the New Jerusalem of the Apocalypse, coming down from heaven in the messianic times to the spiritual Jerusalem in the heart of the believers. Already in Patristic literature, this conception of Jerusalem became the cornerstone of the mystical visio pacis. Since the early Middle Ages, various reproductions of Jerusalem, and in particular of its core for the Christians, i.e., the Church of the Anastasis, began to appear in Western Europe, as so many eidola of Jerusalem. In a sense, this phenomenon of the translatio Hierosolymae is the physical expression of the Christian conquest of Europe.

What is the nature of the links between the idea of a heavenly or spiritual Jerusalem and the multiple Jerusalems sprouting on European soil ? And what are the dialectical relationships between the multiple reproductions of the sacred space and the impetus to reconquer the Holy City itself ? The various mental (re)constructions of Jerusalem reflect different types of piety, different approaches to memory, cult, and religious imagination. From Origen to Swedenborg, this paper investigates some implications of the "blowing up" of Jerusalem, as it were, in Christian consciousness.

Published: June 2020

Gastric cancer is closely related to the stomach microbiota, especially Helicobacter pylori. Numerous reports and clinical studies have shown that microbial behavior in the stomach may lead to pathological changes in the gastrointestinal tract of the host, which ultimately leads to the production and development of gastric cancer. This review outlines the major pathogenic processes of Helicobacter pylori in the stomach, specifically focusing on CagA, VacA, inflammatory pathways and oxidative stress. In addition, we describe the effects of some non-Helicobacter pylori factors, such as other microbiota, alcohol, and tobacco, on the carcinogenesis induced by Helicobacter pylori. The effects of family history are also taken into account. We hope that understanding the stomach microbiota will make it possible to more easily prevent, detect and treat gastric cancer.
High Expression of CDCA7 Promotes Cell Proliferation, Migration, Invasion and Apoptosis in Non-Small-Cell Lung Cancer

Published: June 2020

Objective

Increased expression of CDCA7 is associated with a poorer prognosis in patients with nonsmall-cell lung cancer (NSCLC). This study was performed to investigate the effects of down-regulating cell division cycle-associated 7 (CDCA7) gene expression on the proliferation, migration, invasion, cell cycle and apoptosis of human NSCLC cell lines.

Methods

Cultured A549 and NCI-H292 cells were transfected with siNC(control group) or siCDCA7(experimental group). Cell activity was detected using the CCK-8 and a Real Time Cell Analyzer (RTCA). Cell migration and invasion were also measured by RTCA. In addition, flow cytometry was used to assess the cell cycle progression and apoptosis in the cells, and Western blotting was used to detect the expression level of proteins in key signaling pathways.

Results

Compared with the cells transfected with siNC, the cell proliferation was significantly reduced (P < 0.05), the migration and invasion were decreased, and the cell cycle was blocked in the G0/G1 phase (P < 0.05) in the cells transfected with siCDCA7. The number of cells undergoing apoptosis was also increased (P < 0.05). Western blotting revealed that P-ERK, Cyclin-D1, Vimentin and Bcl-2 were all downregulated. However, the expression of E-cadherin was not affected by the down-regulation of CDCA7, suggesting that it is upstream of this gene.

Conclusion

Silencing the CDCA7 gene inhibited the proliferation, migration and invasion of A549 and NCI-H292 cells, hindered the cell cycle transition to the S phase, and promoted cell apoptosis. These findings indicate that CDCA7 may represent a new therapeutic target for NSCLC.
Reporte de caso clínico: Infarto isquémico cerebral por mecanismo embólico paradójico a través de fístula arterio-venosa pulmonar secundaria a enfermedad de Rendu-Osler-Weber

El infarto isquémico cerebral representa la mayoría de los accidentes vasculares cerebrales y se caracteriza por la disminución del flujo sanguíneo cerebral que resulta en muerte celular. El síndrome de Rendu-Osler-Weber o telangiectasia hemorrágica hereditaria, HHT por sus siglas en inglés, es una enfermedad genética de tipo autosómica dominante. Se presenta con malformaciones arteriovenosas por la expresión del gen afectado sobre las células endoteliales. Este reporte describe el caso clínico de una femenina de 44 años con antecedente de cefalea crónica episódica de características migrañosas desde la juventud. Consulta por cuadro de inicio súbito caracterizado por pérdida del equilibrio, cefalea holocraneal y hemiparesia del hemicuerpo izquierdo. Además, se documenta que la paciente realizó un viaje en avión de más de 11 horas de duración, lo cual favorece la enfermedad trombótica. Se realizan distintos estudios radiológicos y se demuestra la oclusión de la arteria cerebral media derecha, la arteria cerebral anterior derecha y de la arteria cerebral posterior izquierda. Además, una resonancia magnética nuclear cardiotorácica pone en evidencia la presencia de una fístula arteriovenosa pulmonar. Se aplica tratamiento fibrinolítico con Alteplase y se realiza una embolización percutánea de la fístula. El estudio genético confirma la presencia de HHT.
Çinko-Demir Kaplı Elektrot Yüzeyindeki Poli(anilin-co-pirol) ve Poli(anilin-co-N-metilpirol) Kopolimerlerin Korozyon Performansı
Authors: AKDAĞ Abdurrahman
Published: June 2020

Poli(anilin-co-pirol) (PANI-co-PPy) ve poli(anilin-co-N-metilpirol) (PANI-co-PNMP) kopolimer filmler ZnFe kaplı karbon çelik (KÇ/ZnFe) elektrot yüzeyine elektrokimyasal olarak sentezlenmiştir. ZnFe kaplama için galvanostatik yöntem, kopolimer kaplamalar için ise dönüşümlü voltametri yöntemi kullanılmıştır. PANI-co-PPy film 0.05 M anilin + 0.05 M pirol içeren 0.3 M okzalik asit çözeltisinde sentezlenmiştir. PANI-co-PNMP film ise 0.05 M anilin + 0.05 M N-metilpirol içeren 0.3 M okzalik asit çözeltisinde sentezlenmiştir. PANI-co-PPy ve PANI-co-PNMP kopolimerleri ile kaplı elektrotlar doğrusal taramalı voltametri, elektrokimyasal empedans spektroskopisi ve anodik polarizasyon teknikleriyle karakterize edilmiştir. Doğrusal taramalı voltametri sonuçları kopolimer kaplamaların altında ZnFe alaşımının bulunduğunu göstermiştir. Elektrokimyasal empedans spektrsokopisi bulguları PANI-co-PNMP kaplı KÇ/ZnFe (KÇ/ZnFe/PANI-co-PNMP) elektrodun polarizasyon direncinin (Rp) PANI-co-PPy kaplı KÇ/ZnFe (KÇ/ZnFe/PANI-co-PPy) elektroda göre daha yüksek olduğunu ortaya koymuştur. Anodik polarizasyon eğrileri en düşük akım ve en yüksek korozyon potansiyeline sahip elektrodun KÇ/ZnFe/PANI-co-PNMP elektrot olduğunu göstermiştir.

El plátano (Musa paradisiaca L.) representa el principal producto de exportación del Ecuador, especialmente de la provincia de Manabí; sin embargo, se presenta un fenómeno de deterioro de la fertilidad y degradación del suelo, por lo que existe la necesidad de mitigarlo mediante estrategias de fertilización. Se realizó un estudio en la granja experimental Río Suma, Universidad Laica Eloy Alfaro de Manabí, con el objetivo de evaluar la eficiencia de la dosis de fertilización y el fraccionamiento de P en plátano 'Barraganete' en una finca de Manabí, Ecuador. Se utilizó una densidad de población alta (2200 plantas ha-1) y se aplicó una dosis estándar de 100 kg ha-1 de N, 200 kg ha-1 de K2O y 70 kg ha-1 de MgO. Los factores de estudio fueron fertilización con P en tres niveles (20, 40 y 60 kg ha-1 de P2O5) y fraccionamiento en dos niveles (100 y 40-60 % de P2O5), lo que resultó en un arreglo de tratamientos factorial 3 × 2 + 1 de tratamientos, distribuidos en un diseño experimental en bloques completos al azar con tres repeticiones; la unidad experimental estuvo conformada por 21 plantas, de las cuales se seleccionaron cinco de la parte central para las evaluaciones. Las variables evaluadas fueron eficiencia agronómica (EA), factor parcial de productividad (FPP), balance parcial de nutrientes (BPN), biomasa seca del fruto, rendimiento, concentración y exportación de P2O5; esta última fue mayor con 40 kg ha-1 y fraccionamiento de 100 % (6.01 kg ha-1). EA, FPP y BPN presentaron los valores mayores: 211.3, 1002.5 y 0.21 kg ha-1 con la dosis de 20 kg ha-1 y fraccionamiento 40-60 %. El fraccionamiento 40-60 % con dosis de 20 kg ha-1 generó el rendimiento mayor (20,050 kg ha-1). La relación entre la dosis y el fraccionamiento fue inversamente proporcional, mientras que entre el rendimiento y la eficiencia agronómica del P la relación fue cuadrática. Así, las recomendaciones apropiadas pueden establecerse para la fertilización del cultivo con P2O5.
Estados Unidos y el combate contra el narcoterrorismo como lineamiento de política exterior central en el vínculo con América Latina:
Authors: Calderón Emilse
Published: June 2020

Partiendo del supuesto de que las relaciones entre Estados Unidos y América Latina están fuertemente determinadas por la agenda de seguridad, este artículo propone examinar el vínculo cooperativo que establece Washington con Bogotá en función del combate contra el narcotráfico y el terrorismo como modo de aproximación al tipo de relacionamiento que propone el país del norte para la región latinoamericana en el siglo XXI. Consecuentemente, se intenta sustentar la observación de dos tendencias, por un lado, el afianzamiento de la militarización de la influencia norteamericana y de su conducción por parte del Departamento de Defensa y, por el otro, la participación militarizada de Estados Unidos en el conflicto armado colombiano mediante la inclusión de éste como parte de la lucha contra el terrorismo internacional. La metodología utilizada para la confección del escrito es cualitativa y se aplica a un proceso investigativo basado en fuentes primarias y, también, secundarias.

De la permisibilidad a la restricción. Un análisis de la incidencia de los condicionantes sistémicos sobre la política exterior del kirchnerismo (2003-2015)*
Authors: Actis Esteban , Busso Anabella , Calderón Emilse , Zelicovich Julieta
Published: June 2020

Existe un consenso amplio sobre la importancia que los condicionantes domésticos tuvieron en el diseño de la política exterior durante los gobiernos de Néstor y Cristina Kirchner. En consonancia con ese diagnóstico los condicionantes sistémicos han tendido a ser dejados de lado en los estudios referidos a la política exterior argentina durante esa etapa. Por ello, en este trabajo, pretendemos cubrir parte de esa laguna. Consecuentemente argumentamos, a modo de hipótesis, que los condicionantes sistémicos no fueron constantes en los doce años de gestión kirchnerista, sino que mudaron desde un perfil permisivo a uno más restrictivo en el segundo mandato de Cristina Fernández. Esta dinámica tuvo impacto sobre múltiples dimensiones de la Política Exterior, pero fue más evidente en el ámbito económico

Cambio Climático y Energía:
Authors: Bueno María del Pilar , Calcagno Duilio Lorenzo
Published: June 2020

El presente artículo tiene como objetivo analizar algunos aspectos del debate relativo a la díada cambio climático-transición energética en el contexto de adopción e implementación del Acuerdo de París. En tal sentido, primero se identifican tres posturas características en la bibliografía respecto a dicho binomio: optimista, transnacionalista y tecnocrático; pesimista; y realista, gradualista. Luego, y a partir de una breve caracterización del proceso multilateral en la Convención Marco de Naciones Unidas sobre Cambio Climático, se estudian las contribuciones nacionales presentadas por los diez países que generan mayor cantidad de emisiones totales de GEIs a nivel global con el fin de identificar en qué sentido los esfuerzos comprometidos se orientan hacia dicha transición.

Bolivia y Chile ante la CIJ:
Authors: Ceppi Natalia
Published: June 2020

El 24 de abril de 2013 Bolivia presentó una demanda versus Chile ante la Corte Internacional de Justicia (CIJ) reclamando la falta de cumplimiento por parte de su vecino de negociar una salida soberana al Océano Pacífico. A diferencia de otros momentos de la relación bilateral, el objeto del reclamo no consistió en denunciar el Tratado de 1904, sino que el foco estuvo puesto en la presencia de un sinnúmero de hechos que darían cuenta de la existencia de dicha obligación entre las partes. Luego de atravesar las fases escritas y orales establecidas por reglamento, el tribunal internacional desestimó, el 1º de octubre de 2018, la demanda boliviana, poniendo así punto final al abordaje jurídico del conflicto. En este artículo, se identifican los ejes centrales que atraviesan transversalmente las posturas de Bolivia y Chile, como demandante y demandado, respectivamente, para luego, reflexionar sobre el futuro de este vínculo tan complejo y particular
“Sin sangre en la cara…”: (des) honestidad, normas sociales y procesos económicos
Authors: Rocha Torrico José Antonio , Rocha Balboa José Manuel
Published: June 2020

En base al método de Mazar et al. (2008), el presente estudio investiga sobre el grado de (des)honestidad en el que incurren los individuos. Se llevaron a cabo dos experimentos conductuales en los que participaron 685 estudiantes de dos facultades de la Universidad Mayor de San Simón (UMSS). Ambos experimentos generaron, mediante análisis de varianza (ANOVA) y pruebas de suma de rangos de Kruskal-Wallis, dos hechos fundamentales: i) los individuos son deshonestos, aunque sin llegar al máximo nivel de engaño, y ii) la descripción de un contexto que involucra discernimiento moral incentiva en mayor grado a la honestidad en estudiantes de Ciencias Humanas, en contraste con los estudiantes de Ciencias Económicas. Ambas evidencias corroboran, por un lado, que la toma de decisiones de los agentes está influenciada por un conglomerado de normas informales, asumidas individualmente y/o determinadas socialmente y, por otro, ponen en duda el postulado del homo economicus.
