Authors: De la Cruz-Elizondo Yadeneyro , Fontalvo Buelvas Juan Camilo
Published: October 2020

Los suelos de las ciudades tienen una historia de formación particular, lo que hace que tengan propiedades variables que deben ser ajustadas cuando se tiene la intención de darles un uso agrícola. En este trabajo evaluamos la calidad del suelo de un área verde urbana en Xalapa, Veracruz (México), previo a la implementación de un huerto universitario, a través de la determinación rápida de algunas propiedades físicas, químicas y biológicas. Se tomaron muestras de suelo mediante la técnica descrita por la NOM-021 RECNAT-2000 y el método de TSBF. Los resultados obtenidos mostraron que el suelo evaluado es de color café y de textura franco arenosa, con agregados de pobre estabilidad, la densidad aparente (DA) fue de (2.52 g/cm3), la capacidad de campo (CC) fue de 49.04 %, su pH es óptimo para el cultivo de hortalizas (6.58) y la materia orgánica (MO) es de clase media (6.45 %). A nivel biológico, la densidad de lombrices fue de 67.2 ind/m2 y el número grupos edáficos (5) por metro cuadrado resultó ser pobre. La cantidad de hojarasca en el mantillo (118.4 g/m2) y la profundidad de las raíces (30.3 cm) fue moderadamente buena; además, la respiración microbiana y los miligramos de glomalina mostraron indicios de que los procesos enzimáticos se están desarrollando eficientemente. La calidad del suelo evaluado fue de condición moderada; sin embargo, es necesario establecer un plan de manejo integral del suelo para mejorar algunas propiedades y fortalecer otras de forma sinérgica
EVALUACIÓN DE CORRECTIVOS DE ACIDEZ EN UN ANDISOL CULTIVADO CON AGUACATE “HASS”.
Authors: Gutiérrez Nathalia , Restrepo Francisco
Published: October 2020

La acidez del suelo es uno de los grandes limitantes para la producción de cultivos ya sea por deficiencias nutricionales o toxicidades en las plantas, comúnmente por aluminio en suelos tropicales. El objetivo de esta prueba de campo fue evaluar la efectividad de tres enmiendas formuladas a partir de diferentes fuentes en la corrección de acidez y su incidencia sobre el contenido de Calcio (Ca), Magnesio (Mg) y Aluminio (Al) intercambiable de un Andisol ubicado en Guática (Risaralda – Colombia). La composición y dosis de cada tratamiento fue: 1) M1  (30% CaO, 13% MgO, 3% P2O5, 3% S y 12% SiO2), 3 kg/árbol; 2) M2 (55% CaO y 45% MgO), 1 kg/árbol y 3) M3 (3.12% K2O, 27.5% CaO, 11.74% MgO y 4.7% S), 0.3 Kg/árbol respectivamente. Periódicamente se tomaron muestras de suelo a una profundidad de 0 a 20 cm para el análisis de pH, Ca+2, Mg+2 y Al+3 intercambiables. Adicional, se instalaron 3 sondas a profundidades de 20,40 y 60 cm para M1 y M2 y se tomó el pH directamente de la solución del suelo. El correctivo M1 compuesto con silicio y sulfatos resultó significativamente más eficaz en comparación con las otras mezclas al aumentar el pH de manera inmediata y permanente en el suelo y en la solución a las diferentes profundidades evaluadas, además de neutralizar y disminuir el aluminio intercambiable hasta 15 veces, respecto a la condición inicial.  En la medida que el pH aumentó y disminuyó el aluminio, los contenidos de Ca+2 y Mg+2 intercambiable aumentaron progresivamente sin diferencia significativa entre tratamientos.
LOS SUELOS Y LA AGRICULTURA ECOLÓGICA EN LA ERA DE LA POSTVERDAD
Authors: Ibáñez Juan José
Published: October 2020

Los suelos y la agricultura ecológica han sido dos temas soslayados durante décadas de la corriente principal de la literatura científica. Sin embargo, más recientemente, el reconocido fracaso de la agricultura industrial, así como la comprensión del sistema climático, han relanzado el interés por ambas disciplinas. Ya no se discute la importancia de los suelos en el funcionamiento de la biosfera, ni la necesidad de reemplazar una agricultura despilfarradora de recursos y contaminante por otra basada en genuinos principios ecológicos. Sin embargo, desde finales del siglo XX, la ciencia ha ido cambiando, tanto en sus objetivos como es su praxis, siendo paulatinamente reemplazada por lo que actualmente se denomina Tecnociencia. Esta última no persigue tanto progresar en el conocimiento del mundo, como en ser el soporte del progreso e innovación del tejido empresarial de los países, en un mundo frenéticamente competitivo a la par que insustentable. De este modo la búsqueda de la verdad ha sido reemplazada por la posverdad, en la que los científicos somos meros elementos de un sistema muy complejo, dominado por intereses económicos y geopolíticos. En este contexto, la definición de agricultura ecológica depende de los intereses de los actores implicados, relegando los aspectos técnicos a un segundo plano. En este artículo, el autor intenta discernir el futuro de una agricultura genuinamente ecológica, conforme al método científico y que necesita inexcusablemente de una gestión sostenible de los suelos, de aquellas narraciones sesgadas por intereses ajenos a la ciencia, es decir repletas de posverdades.

To be able to determine the type of tobacco that provides maximum profit for farmers in Lita from the types of tobacco leaf forms that are sold, it is necessary to conduct a study entitled "Economic Efficiency of Virginia Tobacco Farming Based on the Forms of Selling Wet Leaves and Dry Leaves in Sakra Barat District, East Lombok Regency" . Efficiency measurement using Revenue Cost Ratio (R / C). The unit of analysis in this research is farmers who do Virginia tobacco farming in the form of selling wet and dry leaves. Of the 16 Villages in West Sakra Subdistrict, four villages were selected by purposive sampling with the consideration that the four villages had the highest number of Virginia tobacco farmers. The four villages are Rensing Village, Jero gunung Village, Pematung Village, Rensing Raya Village. Determination of respondents is done by Quota Sampling, namely sampling based on a certain amount / quota. Based on the results of the analysis, the average income of wet leaf farmers was IDR 7,670,120 / LL or IDR. 065,013 / Ha and the average income of dry leaf farmers was IDR 60,832,656 / LLG or IDR 40,555,104 / Ha. The average R / C value for the sale of wet leaves is 2.4 and the R / C value for dry leaves is 3.4, it means that the sale of wet leaves and dry leaves is equally feasible because they have a higher R / C value> 1. compared to wet leaf sales.

Published: October 2020

Motivated from the employment report which reveals the still high percentage of NEE in Indonesia, using the IFLS5 data we conduct studies related to the impact of sosio-demographic characteristics and local indicators and labor markets on NEE young age. NEE is a heterogeneous population based on attitudes and time availability from a young age towards work (Salvà-Mut, Tugores-Ques, Quintana-Murci, 2017) so that grouping can capture patterns of vulnerability and young age transition decisions to the labor market which is produce appropriate recommendations. The estimation results indicate that NEE carers-cared have characteristics as young women, low education, married status and come from underprivileged backgrounds and tend to be in rural areas with high local unemployment rates. While NEE unemployed is also characterized by young age, but the dominant of men with unmarried status and education is higher than non-NEE, besides it tends to be in urban areas and is influenced by high local unemployment rates. However, it is different from the previous categories, although NEE discourage is also young, male dominated and education level is low. But this category is not affected by regional indicators and the local labor market, due to their lack of perceptions and attitudes towards work. Termotivasi dari laporan ketenagakerjaan yang mengungkapkan masih tingginya persentase NEE di Indonesia, maka dengan menggunakan data IFLS5 kami melakukan kajian terkait dampak karakteristik-karakteristik individu, pendidikan, latar belakang keluarga dan indikator wilayah dan pasar kerja lokal terhadap usia muda yang NEE. Kami tertarik untuk meneliti NEE sebagai populasi yang heterogen dengan cara mengelompokkannya berdasarkan atas sikap dan ketersediaan waktu dari usia muda terhadap pekerjaan (SalvÃ -Mut, Tugores-Ques, Quintana-Murci, 2017), agar dapat menangkap pola kerentanan dan keputusan transisi usia muda ke pasar kerja sehingga dapat dihasilkan rekomendasi kebijakan yang tepat. Hasil estimasi menunjukkan bahwa NEE carers-cared mempunyai karakteristik sebagai perempuan yang berusia muda, tingkat pendidikan rendah, berstatus sudah menikah dan berasal dari latar belakang keluarga yang kurang beruntung terkait ekonomi dan cenderung di pedesaan dengan tingkat pengangguran lokal yang tinggi. Sedangkan NEE unemployed juga mempunyai karakteristik berusia muda, tapi dominan berjenis kelamin laki-laki dengan status belum menikah dan tingkat pendidikan lebih tinggi dibandingkan dengan bukan NEE, selain itu kategori ini cenderung di perkotaan dan juga dipengaruhi oleh tingkat pengangguran lokal yang tinggi. Namun berbeda dengan dua kategori sebelumnya, walaupun discourage juga cenderung berusia muda, berjenis kelamin laki-laki dan tingkat pendidikan rendah, tapi usia muda ini tidak terpengaruh oleh indikator wilayah dan pasar kerja lokal. Hal ini dikarenakan kurangnya persepsi dan sikap terhadap pekerjaan.

Parallelizing a serial code: open–source module, EZ Parallel 1.0,
and geophysics examples
Authors: Turner Jason Louis , Stechmann Samuel N.
Published: October 2020

Abstract. Parallel computing can offer substantial speedup of numerical simulations in comparison to serial computing, as parallel computing uses many processors simultaneously rather than a single processor. However, it typically also requires substantial time and effort to convert a serial code into a parallel code. Here, a new module is developed to reduce the time and effort required to parallelize a serial code. The tested version of the module is written in the Fortran programming language,while the framework could also be extended to other languages (C++, Python, Julia, etc.). The Message Passing Interface is used to allow for either shared-memory or distributed-memory computer architectures. The software is designed for solving partial differential equations on a rectangular two-dimensional or three-dimensional domain, using finite difference, finite volume, pseudo-spectral, or other similar numerical methods. Examples are provided for two idealized models of atmospheric and oceanic fluid dynamics: the two-level quasi-geostrophic equations, and the stochastic heat equation as a model for turbulent advection–diffusion of either water vapor and clouds or sea surface height variability. In tests of the parallelized code, the strong scaling efficiency for the finite difference code is seen to be roughly 80 % to 90 %, which is achieved by adding roughly only 10 new lines to the serial code. Therefore, EZ Parallel provides great benefits with minimal additional effort.
Microbial communities and their predictive functional profiles in the arid soil of Saudi Arabia
Authors: Khan Munawwar A. , Khan Shams T.
Published: October 2020

Abstract. Saudi Arabia has the world's fifth-largest desert and is
the biggest importer of food and agricultural products. Understanding soil
microbial communities is key to improving the agricultural potential of the
region. Therefore, soil microbial communities of the semiarid region of
Abha, known for agriculture, and arid regions of Hafar Al Batin and Muzahmiya
were studied using Illumina sequencing. The results show that the microbial
communities of the Saudi desert were characterized by the presence of high
numbers of Actinobacteria, Proteobacteria, and Firmicutes. In addition to
Sahara desert signature phyla like Gemmatimonadetes, biogeochemically important
microorganisms like primary producers, nitrogen fixers and ammonia oxidizers
were also present. The composition of the microbial community varied greatly
among the sites sampled. The highest diversity was found in the rhizospheric
soil of Muzahmiya followed by Abha. Firmicutes, Proteobacteria and
Actinobacteria were the three main phyla detected in all the samples. Soils from
the agricultural region of Abha were significantly different from other
samples in containing only 1 % Firmicutes and 3–6 times higher
population of Actinobacteria and Bacteroidetes, respectively. The presence
of photosynthetic bacteria, ammonia oxidizers, and nitrogen fixers along
with bacteria capable of surviving on simple and unlikely carbon sources
like dimethylformamide was indicative of their survival strategies under
harsh environmental conditions in the arid soil. Functional inference using
PICRUSt analysis shows an abundance of genes involved in photosynthesis and
nitrogen fixation.
32-year record-high surface melt in 2019/2020 on north George VI
Ice Shelf, Antarctic Peninsula
Authors: Banwell Alison F. , Datta Rajashree Tri , Dell Rebecca L. , Moussavi Mahsa , Brucker Ludovic , Picard Ghislain , Shuman Christopher A. , Stevens Laura A.
Published: October 2020

Abstract. In the 2019/2020 austral summer, the surface melt duration and extent on the northern George VI Ice Shelf (GVIIS) was exceptional compared to the 31 previous summers of dramatically lower melt. This finding is based on analysis of near-continuous 41-year satellite microwave radiometer (and scatterometer) data, which are sensitive to meltwater on the ice-shelf surface and in the near-surface snow. Using optical satellite imagery from Landsat 8 (since 2013) and Sentinel-2 (since 2017), record volumes of surface meltwater ponding are also observed on north GVIIS in 2019/2020, with 23 % of the surface area covered by 0.62 km3 of meltwater on January 19. These exceptional melt and surface ponding conditions in 2019/2020 were driven by sustained air temperatures ≥ 0 °C for anomalously long periods (55–90 hours) from late November onwards, likely driven by warmer northwesterly and northeasterly low-speed winds. Increased surface ponding on ice shelves may threaten their stability through increased potential for hydrofracture initiation; a risk that may increase due to firn air content depletion in response to near-surface melting.
Reproductive Coercion and Legal Recognition: Views of Domestic Violence Support Workers and Lawyers
Authors: Douglas Heather , Sheeran Nicola , Tarzia Laura
Published: October 2020

Reproductive coercion is increasingly recognised as a common part of women’s experiences of domestic violence. The term refers to behaviour that aims to compromise a woman’s control over her reproductive choices. It includes coercing a woman to become pregnant or to terminate a pregnancy and sabotaging contraception. There is no Australian research exploring how domestic violence support and legal services understand and respond to reproductive coercion when it is raised. Drawing on focus group discussions, this article questions the use of the terminology ‘reproductive coercion’ suggesting that ‘reproductive abuse’ may be more accessible. The article finds that the response to reproductive coercion in the legal context may be similar to sexual violence allegations, particularly regarding difficulties associated with reporting and with the victim being believed. This connection is worthy of further investigation. The article concludes that legislative change may improve the recognition of reproductive coercion.

Pursuing the Energetic yet Enigmatic Particle that Powers English Communication
Authors: Bryant Dennis Michael
Published: October 2020

English is determined to use words in multiple scenarios and her determination extends, unmistakeably, to one energetic preposition particle. However, an irony exists here because prepositions are generally rather small words, and easily overlooked by speakers and grammars. Indeed the particle under discussion is merely a two-letter word, but its usage must be described as phenomenal. This paper claims that this particle easily outstrips its preposition peers in aptitude, a talent that can be demonstrated by cataloguing its numerous placements. Apart from demonstrating a plethora of placements, this paper offers a single, yet innovative grammatical definition to cover the particle’s usage. In this regard, this paper advances the OF-insertion hypothesis. The methodology herein is to employ exemplar sentences to demonstrate the particle’s roles. Such a technique has proven its validity in recently published papers on English Grammar. It is true of course that such a particle did not appear out of the blue, hence some exemplars are necessary to demonstrate its growth over grammatical time. Beneficiaries of this paper’s findings will be English as a Second Language teachers, in that they will have a comprehensive endowment from which to teach which, it is hoped, will empower their ESL students’ progress towards full fluency.
Book Article Review: Defending and Creating Place Identities
Authors: Ahmed Ar. Sayed
Published: October 2020

The authors selected four neighborhoods in Melbourne. Two older suburbs, Camberwell and Fitzroy; were in threat from the new development challenges. Characters are something pre-existed. Here dominant architectural styles with heritage value also regarded as important factor. On the other hand, two new housings like Beaconcove and Caroline Springs were modeled after imposed character. They tried to find place identities in residential developments. For that, front gardens of suburbs had been identical marketing agenda which created instinct character of space. To find out the real character of space, authors asked several questions to the inhabitants: how they react about mixed ethnicity, building code’s impact over planning decisions and at which limit they might tolerate change for the sense of place? This review will try to find the place making extracts from the book ‘Becoming spaces'.

Compulsory English Language Teaching in Taibah University at Undergraduate Level: Problems and Challenges
Authors: Ahmad Khan Waquar
Published: October 2020

Believe it or not, attitude can be an obstacle.To learn any language, positive attitude is prerequisite, and a learner needs to go for it. Learning English as a foreign language is certainly not an easy task. Particularly if you are learning English in a non-English-speaking country. English language teaching and learning always attracts the attention of young minds and young generations across the globe for many pedagogical, sociolinguistic, and economic reasons. The present study focuses on teaching English to the students of Arabic and Islamic studies as their compulsory paper at Taibah University. The research paper is based on action research carried out at Al Ula campus, Taibah University. Compulsory English course specification caters to a mixed and mostly large group of students who belong to different social, cultural, economic, and regional background. It is because of this reason; the primary focus of this study is to find out the problems and challenges among learners and teachers. More precisely, the impact and interference of mother tongue (Arabic), lack of opportunity to use English in day to day activities, approach concerning learning English, and inefficacy of EFL learning and teaching.

El objetivo de esta investigación fue analizar la autoeficacia, la participación social y la percepción de los servicios universitarios entre los hombres y las mujeres que estudian educación superior en una universidad de Michoacán, México. El estudio fue cuantitativo y transversal. Participaron 587 estudiantes universitarios, quienes respondieron a una Escala de Autoeficacia, a otra de Participación Social y a un Cuestionario sobre el Uso y Satisfacción de los Servicios de Atención Estudiantil. Se encontraron diferencias significativas entre hombres y mujeres en la autoeficacia deportiva y en la autoeficacia para resistir la presión. También se identificó mayor participación social en los hombres que en las mujeres y escaso contacto con la oferta de servicios universitarios en ambos. En conclusión, se requiere mayor difusión de los servicios universitarios de atención estudiantil, además de promover que estos aumenten la autoeficacia y la participación social, tanto en hombres como en mujeres.

El presente artículo, desarrollado en medio de un contexto de movilizaciones sociales nacionales y reformas globales, buscó develar las principales concepciones sobre la docencia que aparecen y se promueven a través del nuevo marco regulatorio del sistema escolar chileno. Para ello, se utilizó la metodología de análisis crítico del discurso, con la finalidad de identificar las concepciones históricas más recurrentes e interpretar cómo se posiciona a los/as docentes dentro del proceso educativo. La muestra fue elegida de manera intencional y consistió en cuatro leyes educativas chilenas y documentos asociados promulgadas entre los años 2008 y 2011. Los resultados más importantes refieren a que las leyes contienen un discurso empresarial que desplaza el educacional a la hora de referirse al sistema educativo. Así, se buscan transformar discursivamente los roles y concepciones docentes tradicionales, siendo reducida la docencia a tareas y habilidades técnicas constantemente estandarizadas y evaluadas. Sumado a esto, se les posiciona en un rol pasivo de participación e influencia en el proceso educativo de los estudiantes, donde los saberes pedagógicos son desplazados por los saberes de gestión.

El objetivo de este estudio fue relacionar la participación política y el autoritarismo, suponiendo que este implicaría un menor grado de participación política. Mediante el método de selección probabilística incidental, se obtuvo una muestra de 233 participantes voluntarios con edades comprendidas entre los 18 y los 73 años (M = 32,86; DT = 14,085). Los resultados aportan evidencias empíricas sobre las diferencias significativas en el factor “agresión autoritaria” de la Escala Autoritarismo de Derechas (RWA), suponiéndose una relación inversa con la participación política. No se hallaron diferencias en cuanto al sexo en la participación política, aunque sí respecto a la edad, donde se obtuvieron mayores puntuaciones de participación en las personas con edades superiores a 46 años. Asimismo, se encontraron diferencias significativas en la dimensión “electoral” del Cuestionario de Conductas de Participación (CCP) en relación con el nivel de estudios, considerando mayores niveles de participación electoral cuanto mayor es el nivel educativo. Además, se han hallado evidencias empíricas que apuntan a mayor autoritarismo en personas posicionadas en la derecha del espectro político. Se discute sobre las implicaciones de los resultados obtenidos y se plantean futuras líneas de investigación en la temática.

Authors: Pinto-Cortez Cristián , Guerra Cristóbal
Published: October 2020

El objetivo de la presente investigación es determinar la prevalencia de victimización sexual y características asociadas, en una muestra nacional de niños, y adolescentes chilenos. Se trabajó con datos secundarios de la Encuesta Nacional de Polivictimización (2017). La muestra fue de tipo probabilístico e incluyó a 19.684 participantes entre 12 y 18 años (M = 14,7, DT = 1,59) de todas las regiones de Chile continental. Los participantes respondieron una adaptación del Juvenile Victimization Questionnaire (JVQ) que evalúa diferentes formas de violencia. Para este estudio únicamente se consideraron siete ítems referidos a victimización sexual. Los resultados muestran que el 26,4% reporta al menos un tipo de victimización sexual a lo largo de su vida y que el 16,7% reporta al menos una victimización sexual durante los últimos 12 meses. Análisis de regresión logística muestran mayor probabilidad de sufrir victimización sexual en las mujeres, en adolescentes de mayor edad, provenientes de colegios de menor nivel socioeconómico y de regiones. Además, la probabilidad fue mayor en migrantes, en participantes pertenecientes a minorías étnicas y en aquellos con alguna discapacidad. Se discuten estos resultados en vías de la visibilización de la magnitud de la victimización sexual infantojuvenil y de la generación de estrategias de prevención.

Objective: The current study was carried out to assess the prognostic value of androgen receptor expression in urothelial carcinoma of the bladder and correlate it to the disease outcome.Methods: Histologically confirmed cases of bladder urothelial carcinoma were studied. Clinical, pathological, and radiological data were collected. Paraffin embedded tissue sections were submitted for hematoxylin and eosin staining, as well as immunohistochemical staining for androgen receptor in tumor cells.Results: Nuclear androgen receptor expression was positive in 75% of the studied histopathological specimens. Additionally, a significant positive association between androgen receptor expression and tumor grade, muscle invasion & tumor size were noticed.Conclusions: There is a significant association between large tumor size, high grade, deep invasion, and expression of Androgen receptor in urothelial bladder carcinoma. Antiandrogen could be an effective chemo preventive or therapeutic approach in treatment of urothelial bladder carcinoma.

The objective of this paper is to detail preliminary work revolving around modeling. It provides understanding and underpinning implementation procedures of dynamics of large-scale events with Hajj examples, where a large population of people is contained for a significantly long but limited period within certain areas. It is essential to note further that the motivation behind this subject’s discussion could also be fueled by sales, inquiries, or security concerns. However, knowledge emergence on service point procedures implementation suggests that service points implementing data are extinct, and this is obliged to implement the next feature. As such, there is a critical need to reform a process and how to analyze the work.

Developing this literature report requires extensive use of factual data for accuracy; as such, data mining and simulation techniques will be essential in explaining what services are needed. The simulation techniques used herein incorporate several databases targeting to exploit the advantage of proficiency in predicting distribution demand for population points based on available current estimates. Henceforth, data mining, in this case, is used to inform intelligent decision making on investing in services points as pushed for by customers’ demand.
Spatial Analysis of Urban Water Use Management in the Northern Border Region of Mexico
Authors: Castro-Rosales Gregorio , Esqueda-Walle Ramiro
Published: October 2020

This paper estimates water price elasticity and examines spatial patterns of urban water management variables in 70 localities of more than 2 500 inhabitants of the six northern border Mexican states. By using ordinary least squares, spatial econometrics, Lagrange Multipliers, and exploratory spatial data analysis techniques, four variables were analyzed: water price (P), a Non-revenue water index (NRWI), total urban water connections, and water billed volume (BV). In accordance with the literature, we found that water demand is price sensitive but inelastic. Then price as an instrument for controlling water consumption does not offer an efficient alternative for reducing it, as water price increases would have to rise very high to reflect changes in consumption habits. Instead, it could be just a revenue-raising tool. Our findings also confirm a significant spatial autocorrelation in P and the NRWI. More interestingly, we found robust spatial effects on BV. This result implies that the performance of urban water utilities is determined by its counterparts' performance in the region. Given the results and characteristics of water resources in the region, we argue that management policies must consider a regional approach to be effective.
Integrating Diffusion of Innovations and Theory of Planned Behavior to Predict Intention to Adopt Electric Vehicles
Authors: Jung Moon Sun
Published: October 2020

Electric vehicles (EVs) are recognized as effective solutions to the global air pollution problem, attracting much attention from businesses, governments, and consumers. Despite the heightened interest, EV penetration rates remain low. This study thus focuses on consumers’ evaluation of EV innovation to provide implications for promoting EV adoption by proposing a theoretical model that integrates the diffusion of innovations theory and the theory of planned behavior to examine the relationship between consumers’ perceived innovation characteristics and the adoption of EVs; the study findings indicate that the evaluation of consumers’ EV innovation has a significant impact on consumers’ attitudes toward and intention for EV adoption. Several important innovation characteristics promote practical implications for spreading EV acceptance.
Analyzing UK’s Biogas from Waste Scheme Through the Lens of Circular Economy
Authors: Acharya Abhijeet
Published: October 2020

The biogas from waste has emerged as a realistic and reliable renewable energy proposition and can deliver social-economic benefits when integrated with local communities. In the last decade, the biogas sector in European countries has seen unprecedented growth due to favorable policy supports and perceived social-economic benefits. Among different biogas producing schemes, waste to biogas using anaerobic digestion is considered most environment friendly due to minimum carbon leakage and positive waste resource recycling impact. Many countries, including the UK, envision creating a circular economy utilizing Biogas from Waste (BfW) recycling potential. This paper aims to analyze the state of the UK’s BfW scheme through the lens of circular economy and discern areas that need attention to usher BfW potential in supporting a circular economy. The paper also discussed key challenges and barriers to create a local circular economy using the BfW scheme. Based on the analysis, it is observed that the BfW scheme in the UK is currently impeded due to lack cross-sectoral policy coherence, and far from contributing to a circular economy. Additionally, the UK's waste to energy concept is concentrated around incinerator-based systems without much attention on improving resource efficiency and waste recycling. This paper makes three recommendations to improve prospects of the BfW scheme in the UK (1) decentralized approach in the BfW scheme development, (2) considering bio-waste and digestate as value streams, and (3) creating a policy cohesiveness across multiple departments.
El problema eléctrico chileno. Un estudio de caso de controversia sociotécnica (1935-1939)
Authors: Soto Vejar José Eduardo , Sanhueza Cerda Carlos
Published: October 2020

En este artículo estudiamos las controversias sobre la creación de una red eléctrica en Chile que un conjunto de ingenieros mantuvo entre 1935 y 1939. Estas surgieron en conferencias dadas en el Instituto de Ingenieros de Chile. Nuestro objetivo principal es probar que dichas controversias (centradas en el rol del Estado, el mercado y la infraestructura en el desarrollo de la red eléctrica en Chile) definieron una política estatal energética nacional. Estas discusiones también muestran el despliegue de una red sociotécnica y el papel que tuvieron los ingenieros en las políticas de Estado. Así, abordamos un caso propio de los estudios de ciencia, tecnología y sociedad para destacar los vínculos de lo político y lo técnico en el ámbito de la electrificación. Para este artículo, nos basamos principalmente en fuentes primarias de la administración estatal y artículos de la revista Anales del Instituto de Ingenieros de Chile.
