Authors: Safriyani Rizka , Rakhmawati Rakhmawati , Sadieda Lisanul Uswah
Published: August 2021

The development of research-based learning proliferates throughout the world, and it depicts the growth of an academic article's publication globally. To strengthen the paper's quality, particularly in Indonesia, the students need a guideline on writing an academic article. This qualitative and quantitative research would portray the needs analysis in developing a research-based textbook in academic writing. Fifty students and thirty lecturers were involved in the interview, documentation, and survey. The result shows that the skills needed to accommodate are referencing skills, writing the research's significance, and writing the conclusion. This study also suggested nine units of an Academic Writing Textbook needed by the students to produce a good article, namely  Introduction to Academic Article Writing, Strategies in avoiding plagiarism, Writing an introduction, writing a literature review, writing a research method, Presenting Findings and Discussion, Writing a conclusion, Tips on Referencing, choosing the title, and writing an abstract. These findings strengthen the previous studies, which states writing a conclusion of an academic article is challenging, particularly in the English Language Teaching context.

Authors: Putri Ni Made Anggi Arlina , Santosa Riyadi , Rochsantiningsih Dewi
Published: August 2021

A significant change in education instructional goals effects assessment techniques used to evaluate students’ progress. The root of this phenomenon highly offers to authentic assessment as an alternative assessment. This study deals with authentic assessment implementation and its effects within teaching and learning in the context of Year 7 English students. It employs case study to get a in-depth understanding of the case. Data of the study were gained from deep-interview, observation, and document analysis.  While, the data were analyzed by using Interactive model involving data reduction, data displays and conclusions: drawing/verification. The study finds that the relevance of implementation of authentic assessment becomes the main factor of determining its washbacks. Since most the authentic assessment stages undertaken by teachers are in line with National Regulation on how the assessment is designed and implemented, it provides more positive washbacks for both teachers and students such as motivated to be more creative and innovative in teaching and learning process. Nevertheless, the administration of assessment as guided by the government had a negative effect to teachers since it makes them feel overburdened and stressed.

Published: August 2021

Machine learning (ML) and artificial intelligence (AI) researchers play an important role in the ethics and governance of AI, including through their work, advocacy, and choice of employment. Nevertheless, this influential group's attitudes are not well understood, undermining our ability to discern consensuses or disagreements between AI/ML researchers. To examine these researchers' views, we conducted a survey of those who published in two top AI/ML conferences (N = 524). We compare these results with those from a 2016 survey of AI/ML researchers (Grace et al., 2018) and a 2018 survey of the US public (Zhang & Dafoe, 2020). We find that AI/ML researchers place high levels of trust in international organizations and scientific organizations to shape the development and use of AI in the public interest; moderate trust in most Western tech companies; and low trust in national militaries, Chinese tech companies, and Facebook. While the respondents were overwhelmingly opposed to AI/ML researchers working on lethal autonomous weapons, they are less opposed to researchers working on other military applications of AI, particularly logistics algorithms. A strong majority of respondents think that AI safety research should be prioritized and that ML institutions should conduct pre-publication review to assess potential harms. Being closer to the technology itself, AI/ML researchers are well placed to highlight new risks and develop technical solutions, so this novel attempt to measure their attitudes has broad relevance. The findings should help to improve how researchers, private sector executives, and policymakers think about regulations, governance frameworks, guiding principles, and national and international governance strategies for AI.

Dewatering of dredged slurry by horizontal drain assisted with vacuum and flocculation
Authors: Pu H. , Khoteja D. , Zhou Y. , Pan Y.
Published: August 2021

This study proposes a new method using the combination of flocculation and prefabricated horizontal drain (PHD) assisted with vacuum pressure for rapid dewatering of high-water-content dredged slurry. First, to demonstrate the superiority of using PHD over the more commonly used prefabricated vertical drain (PVD), experiments were conducted to compare the dewatering performance between the PHD and the PVD. Then six model tests with the proposed dewatering method were performed with various contents of flocculant (anionic polyacrylamide (APAM)) to investigate the effect of APAM content on the dewatering process and soil properties (i.e. undrained shear strength, permeability and compressibility). Furthermore, particle size distributions of the slurry before and after model tests were measured to analyze the dewatering behavior and changes in material properties. Finally, particle loss during vacuum consolidation for various APAM contents were compared to study the flocculation effect on clogging problem. Results indicate that the proposed method can prevent significant bending deformation of the drain board and mitigate clogging of the drain filter and, thus, can significantly accelerate the dewatering process of high-water-content dredged slurry.
A hyperbolic model for mechanical behaviour of marginal soil-geosynthetic interface
Authors: Ensani A. , Razeghi H. R. , Mamaghanian J.
Published: August 2021

Locally available marginal soils are of great interest to use as backfill material in geosynthetic reinforced soil structures due to their cost-effectiveness. The advanced stress–strain analysis of these structures necessitates the correct evaluation and the accurate description of marginal soil-geosynthetic interface behaviour. Therefore, the primary objectives of this study are numerical and analytical analysis of the soil-geosynthetic interface behaviour with application of a hyperbolic nonlinear elastic perfectly plastic constitutive model. In this investigation a series of large-scale direct shear tests was performed to evaluate the shear stress-displacement interface behaviour considering two types of marginal soils in contact with five types of geosynthetic materials in different soil moisture conditions. Accordingly, the hyperbolic model was used to simulate the soil-geosynthetic interface behaviour. Moreover, a three-dimensional finite element model of the direct shear test was developed using ABAQUS software and a user-defined subroutine was implemented to consider the hyperbolic interface model. The results indicated a very good agreement between the experimental data and the predicted finite element simulations of the direct shear tests and analytical solutions. Finally, a numerical simulation of a pullout test is presented in this paper with application of the hyperbolic interface model.
A quantification of the short-term reliability of HDPE geomembrane seaming methods
Authors: Gilson-Beck A. , Giroud J. P.
Published: August 2021

This study provides a preliminary approximate quantification of the difference in seam reliability between fusion seams and extrusion seams of high-density polyethylene (HDPE) geomembranes based on leaks that exist at the end of installation. The two different seaming methods as well as seam testing methods are discussed. The reliability of the two seaming methods is compared using the number of leaks associated with extrusion seams versus fusion seams, which were found using electrical leak location surveys performed on a sampling of large geomembrane-lined facilities.

Published: August 2021

This study aimed to investigate new bacterial sources with the ability to produce inulinase and to optimize fermentation conditions for inulinase production. The inulinase production was carried out using newly isolated Bacillus licheniformis and Bacillus velezensis among identified sixteen bacterial strains. The four essential variables incubation time (1-3 days), temperature (25-40°C), pH (5-7), and Wheat Bran (WB) level (1-5%) determined by the Plackett–Burman design (PB) were selected for optimization studies with Box-Benhken Design (BBD). These parameters were found to be very effective on inulinase production. The maximum inulinase activities for B. licheniformis and B. velezensis were 401.18 EU/mL and 344.61 EU/mL. Both inulinases sustained 50% of their initial activity at 30°C for 9 days.. The results point out that bacteria are an important source as inulinase producer. The new isolates can be used in production of inulinase for industrial processes.

In the field of critical infrastructures such as natural gas, electricity, water, and energy systems, which are among the smart grids, its use has been increasing in Turkey and all over the world in recent years. With the increase in the use of smart grids, security problems have also gained importance. Cybersecurity attacks against these networks are increasing every year. In this research study, smart cities, smart networks, and the most common cybersecurity attack methods against these systems were investigated. The studies on security in smart grids in the last 10 years have been examined and presented in a table. As a result of these researches, cyber-attacks that are experienced and likely to occur in smart networks were determined. The 20 most used cyber-attack methods were analyzed. In addition, the measures that can be taken against cyber-attacks are analyzed in detail. In addition, in this article, studies on security problems in smart grids are examined and evaluated.
nà-Cleft (non-)exhaustivity: Variability in Akan
Authors: De Veaugh-Geiss Joseph P.
Published: August 2021

This paper presents two experimental studies on the exhaustive inference associated with focus-background nà-clefts in Akan (among others, Boadi 1974; Duah 2015; Grubic, Renans & Duah 2019; Titov 2019), with a direct comparison to two recent experiments on German es-clefts employing an identical design (De Veaugh-Geiss et al. 2018). Despite the unforeseen response patterns in Akan in the incremental information-retrieval paradigm used, a post-hoc exploratory analysis reveals striking parallels between the two languages. The results are compatible with a unified approach both (i) cross-linguistically between Akan and German; and (ii) cross-sententially between nà-clefts (α nà P, ’It is α who did P’) and definite pseudoclefts, i.e., definite descriptions with identity statements (Nipa no a P ne α , ’The person who did P is α ’) (Boadi 1974; Ofori 2011). Participant variability in (non-)exhaustive interpretations is accounted for with a discourse-pragmatic analysis of cleft exhaustivity (Pollard & Yasavul 2016; De Veaugh-Geiss et al. 2018; Destruel & De Veaugh-Geiss 2018).
The Long-Lived Cyclicality of the Labor Force Participation Rate
Authors: Cajner Tomaz , Coglianese John , Montes Joshua
Published: August 2021

How cyclical is the U.S. labor force participation rate (LFPR)? We examine its response to exogenous state-level business cycle shocks, finding that the LFPR is highly cyclical, but with a significantly longer-lived response than the unemployment rate. The LFPR declines after a negative shock for about four years—well beyond when the unemployment rate has begun to recover—and takes about eight years to fully recover after the shock. The decline and recovery of the LFPR is largely driven by individuals with home and family responsibilities, as well as by younger individuals spending time in school. Our main specifications measure cyclicality from the response of the age-adjusted LFPR, and we show that it is problematic to use the unadjusted LFPR when estimating cyclicality because local shocks spur changes in the population of high-LFPR age groups through migration. LFPR cyclicality varies across groups, with larger and longer-lived responses.
Student Loans, Access to Credit and Consumer Financial Behavior
Authors: Sommer Kamila , Mezza Alvaro , Ringo Daniel
Published: August 2021

This paper provides novel evidence that increased student loan debts, caused by rising tuitions, increase borrowers' demand for additional consumer debt, while simultaneously restricting their ability to access it. The net effect of student loan debt on consumer borrowing varies by market, depending on whether the supply or demand channel dominates. In loosely underwritten credit markets, increased student loan debt causes borrowing to increase, while in tightly underwritten markets, increased student loan debt reduces the use of credit. These findings match predictions of a standard lifecycle model of household consumption and borrowing, augmented with a realistic student loan repayment contract.
A Brief History of the U.S. Regulatory Perimeter
Authors: Tabor Nicholas K. , Di Lucido Katherine E. , Zhang Jeffery Y.
Published: August 2021

This paper provides a brief history of the U.S. financial regulatory perimeter, a legal cordon comprised of "positive" and "negative" restrictions on the conduct of banking organizations. Today's regulatory perimeter faces a wide range of challenges, from disaggregation, to new commercial entrants, to new varieties of charters (and new uses of legacy charters). We situate these challenges in the longer history of American banking, identifying a pattern in debates about the nature, shape, and position of the perimeter: outside-in pressure, inside-out pressure, and reform and expansion. We also observe a shift in this pattern, beginning roughly three decades ago, which gradually made the perimeter broader, more complex, and arguably more permeable. We show this trend graphically in an animation accompanying this paper.

Mapping of the determinants of satisfaction with life of portuguese seniors: proposal for preventive intervention at an organizational level
Authors: Pinto Ana , Tavares Aida Isabel , Carvalho Carla , Santos Costa Paulo , Parreira Pedro
Published: August 2021

This study focuses on the impact of demographic, socioeconomic, geographic and health determinants on Portuguese seniors’ life satisfaction. The aim of this research is, therefore, to map the determinants of satisfaction with the life of the Portuguese seniors at a national and regional level. This knowledge brings insights to improve quality of life, starting with prevention in their active life (organizational level). We used data collected by the National Health Survey of 2014 and estimated a linear OLS regression both for Portugal and its regions. The main results show that determinants that contribute positively to the level of satisfaction with life are: marital status of being “married”; higher levels of education; higher levels of income; being men and people living in rural areas. The determinant that contributed negatively to the level of satisfaction with life is the existence of chronic diseases.The results at the regional level maintain the trends observed at the country level, showing income and chronic diseases as determinants that have an impact on life satisfaction in all regions. A general profile of the Portuguese seniors is provided for the country and by region, as well as proposals, generic and transversal, at the organizational level are outlined.
Percepción de la aceptación y el rechazo de los iguales en escolares de educación primaria
Authors: Cedeño Coppiano Carolina , Barajas Esteban Carmen , Linero Zamorano María José
Published: August 2021

La aceptación que los niños/as reciben por parte de sus iguales puede ser muy desigual, así como la percepción que tienen de la aceptación recibida. Tanto la aceptación real como la precisión (o los sesgos) con que la perciben pueden tener consecuencias en la normal adaptación de los niños/as a su entorno social. El objetivo de este estudio es explorar la relación entre la aceptación/rechazo que reciben de sus iguales niños y niñas de Educación Primaria y la percepción de tal aceptación/rechazo, comparando los perfiles de las distintas categorías sociométricas. El estudio se llevó a cabo con una muestra de 97 niños/as (50 niñas y 47 niños) de 6 a 12 años, pertenecientes a centros educativos de Educación Básica de Quito (Ecuador). Se administró un cuestionario sociométrico, a partir del cual se estimó para cada participante su estatus sociométrico (popular, rechazado, controvertido, ignorado, promedio) y medidas de percepción de la aceptación y del rechazo, tanto generalizada como diádica. Los resultados indican que los niños/as rechazados sobrevaloran la aceptación global recibida (piensan que tienen más aceptación de la que realmente tienen); y que, en cuanto a la percepción diádica (o percepción exacta de compañeros/as concretos que los eligen o rechazan), los niños/as ignorados subestiman la aceptación de los escasos compañeros que los eligen, mientras que los populares y promedio subestiman los casos de rechazo que reciben. Los resultados aportan claves interesantes para el diseño de situaciones educativas en las que los escolares tengan la oportunidad de comprobar y ajustar la percepción de la aceptación y/o rechazo de sus compañeros/as.

En marzo de 2020, la pandemia de la COVID-19 hizo que, a lo largo del mundo, muchos países adoptaran medidas basadas en confinamientos domiciliarios. El objetivo era detener la propagación, así como la crisis hospitalaria y las muertes derivadas de la infección por SARS-CoV-2. Las personas tuvieron que reajustar sus hábitos de vida para adaptarse a la nueva situación. El objetivo principal de esta investigación fue evaluar la percepción poblacional sobre los cambios en el estilo de vida experimentados durante su confinamiento domiciliario en torno a cuatro parámetros: (a) su alimentación, (b) la frecuencia/intensidad de ejercicio físico, (c) el estado emocional y (d) el uso de medios digitales de salud digital (eSalud). Con este objetivo, el 31 de marzo y el 1 de abril, se envió el enlace de una encuesta diseñada en Formularios de Google a través de WhatsApp. Se reclutó una muestra de 320 participantes, con edades comprendidas entre los 15 y los 78 años (=32.97; s=11.51), residentes de distintos países americanos y europeos, principalmente de República Dominicana (73.8%) y España (17.2%). Los resultados evidenciaron, respecto a la alimentación, que el 27,2% sentía que su alimentación había empeorado (37.8% que era igual, mientras que 35,0% que incluso había mejorado); en cuanto al ejercicio, 52.5% manifestaba que había disminuido su frecuencia / intensidad (23.1% que era igual, mientras que 24.4% que había aumentado); a nivel emocional, 34.4% señaló que había empeorado (51.6% que era igual, mientras que 14.0% que era más positivo). Se observó una asociación estadísticamente significativa entre los cambios en el uso de herramientas de eSalud en la alimentación (c2[4, n = 320]= 11.75, p =. 019) y el ejercicio físico (c2 [4, n= 320] = 85.35, p =.000). No se observó asociación estadísticamente significativa entre los cambios emocionales y en el uso de herramientas de eSalud.

The coronavirus disease 2019 (COVID-19) pandemic has caused disruption to professional and recreational sports across the world. The SARS-CoV-2 virus can be transmitted by relatively large respiratory droplets that behave ballistically, and exhaled aerosol droplets, which potentially pose a greater risk. This review provides a summary of end-to-end SARS-CoV-2 transmission risk factors for sport and an overview of transmission mechanisms to be considered by all stakeholders. The risk of SARS-CoV-2 transmission is greatest indoors, and primarily influenced by the ventilation of the environment and the close proximity of individuals. The SARS-CoV-2 transmission risks outdoors, e.g. via water, and from fomites, appear less than initially thought. Mitigation strategies include good end-to-end scenario planning of activities to optimise physical distancing, face mask wearing and hygiene practice of individuals, the environment and equipment. The identification and removal of infectious individuals should be undertaken by means of the taking of temperature and COVID-19 symptom screening, and the use of diagnostic monitoring tests to identify asymptomatic individuals. Using adequate video footage, data from proximity technology and subject interviews, the identification and isolation of ‘close contacts’ should also be undertaken to limit SARS-CoV-2 transmission within sporting environments and into the wider community. Sports should aim to undertake activities outdoors where possible, given the lower SARS-CoV-2 transmission risk, in comparison to indoor environments.

Good Behavior Game: History and Modern Trends
Authors: Statnikov A.I.
Published: July 2021

The Good Behavior Game is a behavioral procedure aimed to change the behavior of all members of the student group through an interdependent group contingency. Since the middle of 60s years of XX century the Game is used in primary school and preschool groups, as well as in the secondary and high school, in different cultural contexts and in the context of inclusive education also. In presented paper the following points are reflected: the history of the development of the procedure, typical options for conducting, possible categories of participants, types of the aimed behavior, studies of the effectiveness of the Game usage and the factors influencing it. The paper includes step-by-step description of the one of the possible ways of conducting the procedure. Special attention is paid to the issue of using the Game in groups, which include students with autism. The existing precedents are analyzed. The theoretical perspectives for conducting the Game in such conditions are discussed including methodological base and the match between the procedure and cognitive features, which are often found in people with ASD.
Designing a Energy Efficient Node Disjoint Multipath Routing technique to achieve energy efficiency in Mobile Ad Hoc Networks
Authors: Vivek Arya Haru Gandhi,
Published: August 2021

Mobile Ad Hoc Networks (MANETs) are wireless networks which comprise of mobile nodes with limited energy resources. Every node cooperates to perform routing and expends energy on a frequent basis. Nodes are mobile thus link breakages are common and new routes need to be established quickly. Traditional routing protocols tend to find shortest routes to destination providing best-effort delivery service. However due to limited energy and bandwidth resources shortest path routes may not suffice and may usually degrade the performance of the network. In this paper an Energy aware Node Disjoint routing technique END-AODV is proposed that is based on the traditional AODV protocol. The technique designed is based on the argument that node disjoint multipath routing can conserve energy more efficiently as compared to link disjoint routing. Link Disjoint routing leads to overuse of a subset of nodes thus decreasing the overall network lifetime. The technique proposed incorporates energy drain rate metric to establish energy aware routes which are node disjoint in nature. Simulation results with ns2.34 simulator show efficiency of the proposed technique in terms of packet delivery ratio, average energy consumption per data bit delivered, network lifetime and average end to end delay.

Objetivos: Determinar los hallazgos tomográficos pulmonares asociados a severidad y mortalidad en pacientes con la COVID-19 del Hospital Nacional Edgardo Rebagliati Martins (HNERM), y proponer puntos de corte para una puntuación tomográfica de severidad (PTS). Materiales y métodos: Estudio de cohorte retrospectivo en 254 pacientes con la COVID-19 que contaban con tomografía de tórax clasificado según severidad clínica. Se realizó un análisis multivariado mediante regresión logística para determinar asociación con la severidad clínica, un análisis de regresión de Cox para evaluar mortalidad, y curvas ROC para evaluar la PTS. Resultados: Los hallazgos tomográficos asociados a severidad clínica fueron el patrón difuso de las lesiones (OR: 3,23, IC 95%: 1,46-7,14), patrón en «empedrado» (OR: 2,48; IC 95%: 1,08-5,68) y mayor valor en la PTS (OR: 1,73; IC 95%: 1,49-2,02). Los hallazgos asociados a mortalidad fueron el patrón en «empedrado» (HR: 1,78; IC 95%: 1,03-3,06) y mayor valor en la PTS (HR: 1,33; IC 95%: 1,20-1,48). Un valor de 7 en la PTS tuvo una sensibilidad de 94,4% y especificidad de 100% para identificar casos moderados y un valor de 13 tuvo una sensibilidad de 84,9% y una especificidad de 70,6% para casos severos. Conclusiones: El patrón difuso de las lesiones se asoció a una mayor severidad clínica. El patrón en «empedrado» y un mayor valor en la PTS se asociaron a mayor severidad clínica y a mortalidad. Se proponen los valores de 7 y 13 como puntos de corte de la PTS para identificar casos moderados y severos.

El objetivo del estudio fue determinar la frecuencia de resistencia a la colistina en Pseudomonas aeruginosa provenientes de tres establecimientos de salud de Lima, criopreservados en el banco de cepas del Laboratorio de Resistencia a Antimicrobianos e Inmunopatología de la Universidad Peruana Cayetano Heredia (UPCH). El método de elución de discos de colistina en caldo fue empleado para la identificación fenotípica de la resistencia a la colistina; la detección de la expresión del gen mcr-1 se realizó mediante el método fenotípico de difusión de discos combinados de colistina y ácido etilendiaminotetraacético (EDTA) y la reacción en cadena de la polimerasa (PCR) para la identificación molecular del gen. De los 97 aislados estudiados, 7 (7,2%) fueron resistentes a la colistina y ninguno fue portador del gen mcr-1. Este estudio constituye el primer reporte en el Perú de aislados clínicos de Pseudomonas aeruginosa resistentes a la colistina, lo que implica la necesidad de implementar metodologías apropiadas para la vigilancia epidemiológica de patógenos resistentes a la colistina.

As immersive technologies have become ubiquitous today, traditional museums are finding success augmenting existing exhibits to increase visitors’ satisfaction. However, due to the immutable nature of house museums, and their tendency to place visitors in direct contact with historical artifacts, museum managers are seeking original approaches to cultural preservation. Implementing mixed reality systems into historic house museums is one such approach. The goal of this study is to develop and test a conceptual matrix that guides how designers use the affordances of mixed reality systems to create experiences that align with the range of historical narratives found in house museums. Experiences that can contribute to improving visitors’ satisfaction, self-interpretation, and understanding of the homeowner’s life and the community within which they lived. Building on human-centered design methods, the researcher developed and tested a prototype of an augmented reality (AR) mobile application centered on the Pope House Museum in Raleigh, North Carolina. The outcome of the research suggests house museum visitors should have agency in deciding the lens through which they experience the variety of historical narratives present in the home.

Published: August 2021

This study determines the optimum insulation layer thickness to be applied to external building walls considering the heating degree-day (HDD) method, then energy saving costs, payback periods, and carbon dioxide (CO2) emissions are calculated accordingly. The optimisation analysis is performed for four different thermal insulation materials (glass wool, rock wool, extruded polystyrene, and expanded polystyrene). Natural gas is chosen as fuel for heating purposes, and horizontal perforated brick is preferred in the wall. One of the original features in this study is environmental analysis to determine the CO2 emission for the insulated wall in Turkey provinces. Another feature is that it has the most up-to-date data about HDD values and fuel and insulation material costs. The worst and best insulation materials are obtained as rock wool and glass wool, respectively. The optimum insulation layer thickness for the best case is varied between 0.07 m and 0.23 m, depending on the HDD values of provinces. The annual total energy saving cost is in the range of 4.4–53.5 $/(m2year), and the payback period is 0.11–0.38 years. Besides, the reduction in annual CO2 emission is changed between 53.2% and 94% for the best case, compared to the uninsulated wall.
