Published: August 2022

E-Commerce has had a major impact on social and economic growth in society. However, E-Commerce system is not always profitable for UMKM actors themselves, there are several factors that cause UMKM quality assessments to decline from tight competitiveness. Many consumers consider buying products from the many existing E-Commerce systems. For this reason, this goal is to implement a decision support system in determining E-Commerce using the TOPSIS method with AHP method. Of course, in implementing a decision support system, it is necessary to have assessment criteria and a number of alternatives that will be used as a reference to determine E-Commerce for UMKM by calculating the TOPSIS method which will produce the final result of the value of each E-Commerce in the form of ranking.

An introduction to preventing the transmission of diseases is not only essential during a pandemic because viruses are the closest part of the children. However, this is not easy to teach in early childhood, which is in a substantial period; interesting methods are needed and accepted by children's logic. This study aimed to describe the process of introducing ways to prevent disease transmission in children through learning methods based on Science, Technology, Engineering, Art, and Mathematics (STEAM). This qualitative research method was presented with a descriptive approach. Informants in this study were teachers who teach children aged 5-6 years at TPA Gampong Daulat, Langsa, Aceh. Researchers collected data through observation techniques. The data were analyzed in three stages: data reduction, data presentation and conclusion drawing. The results showed that the STEAM-based learning method was integrated into the concept and practice of health protocols. Ways of transmitting diseases caused by viruses in the form of washing hands, wearing masks, and keeping a distance taught based on the STEAM method make children actively involved and think logically and critically. The effectiveness of the STEAM-based learning method in teaching other aspects of health can be studied further.

Differential expression of ZBTB43 in amyotrophic lateral sclerosis.
Authors: Mamoor Shahan
Published: August 2022

Neurodegenerative diseases that affect the motor neurons, including amyotrophic lateral sclerosis (ALS), have little treatment options and are generally rapidly fatal (1, 2). We harnessed the power of unbiased, whole transcriptome differential gene expression analysis, utilizing primary patient cells and tissues to discover genes whose expression defines sporadic ALS using published data (3, 4). We found significant differential expression of ZBTB43, encoding zinc finger and BTB domain-containing 43, in primary fibroblasts of patients with sporadic ALS (SALS). ZBTB43 transcript was present at significantly lower levels in SALS patient fibroblasts as compared to control, non-diseased fibroblasts. These analyses will begin to define the transcriptional landscape of sporadic ALS.
Human-likeness and attribution of intentionality predict vicarious sense of agency over humanoid robot actions
Authors: Roselli Cecilia , Ciardo Francesca , De Tommaso Davide , Wykowska Agnieszka
Published: August 2022

Sense of Agency (SoA) is the feeling of being in control of one’s actions and their outcomes. In a social context, people can experience a “vicarious” SoA over another human’s actions; however, it is still controversial whether the same occurs in Human-Robot Interaction (HRI). The present study aimed at understanding whether humanoid robots may elicit vicarious SoA in humans, and whether the emergence of this phenomenon depends on the attribution of intentionality towards robots. We asked adult participants to perform an Intentional Binding (IB) task alone and with the humanoid iCub robot, reporting the time of occurrence of both self- and iCub-generated actions. Before the experiment, participants’ degree of attribution of intentionality towards robots was assessed. Results showed that participants experienced vicarious SoA over iCub-generated actions. Moreover, intentionality attribution positively predicted the magnitude of vicarious SoA. In conclusion, our results highlight the importance of factors such as human-likeness and attribution of intentionality for the emergence of vicarious SoA towards robots.
The relationship between smartphone use and smartphone addiction: an examination of logged and self-reported behaviour in a pre-registered, two-wave sample
Authors: Hitcham Lucy , Jackson Hannah , James Richard J. E.
Published: August 2022

Measurements of smartphone addiction weakly correlate with actual behaviour logged from smartphones. Instead, smartphone addiction may probe distress rather than disordered behaviour, but this has not been adequately tested. This study examined the relative contributions of self-reported and actual smartphone behaviour alongside key mental health and individual differences in a pre-registered, two-wave study with a two week re-test. 511 smartphone users (391 at Time 2) completed measures of smartphone usage, attitudes towards smartphone usage, smartphone and other behavioural addictions, and individual differences. Smartphone addiction is principally driven by perceived rather than actual usage, especially where these are discordant. Self-reported smartphone usage, other behavioural addictions, and the impulsive facet of negative urgency are more predictive of smartphone addiction than logged behaviour. These results fail to support the idea that volume of smartphone usage is a sufficient criterion for an addictive behaviour and questions the validity of smartphone addiction measurements.
Más allá de las operaciones del pensamiento salvaje entre los shuar de la Amazonía ecuatoriana
Authors: Abad Espinoza Luis Gregorio
Published: August 2022

Al tratar de disolver la neta separación entre una mente racional y la materia inerte abogada por el dualismo Cartesiano, el monismo lucha por reunificar estas distintas realidades ontológicas. Tal como para Claude Lévi-Strauss y Baruch Spinoza, esa dicha unificación no puede prescindir de la trascendencia de la mente humana como locus del pensamiento y conocimiento de la naturaleza externa. A través de una discusión entre las abstracciones de la etnología Amerindia (animismo-perspectivismo), las teorizaciones del estructuralismo y las relaciones que estos tienen con algunas especulaciones filosóficas occidentales, este artículo trata de analizar las intricadas interacciones humano-naturaleza entre los Shuar de la Amazonía Ecuatoriana. De esta forma, se argumenta que las realidades metafísicas de las experiencias oníricas y visionarias están ontológicamente determinadas por el grado de intensidad de contacto que los humanos establecen con las subjetividades materiales del ecosistema.

The Sky is the Limit: Feng Xiaoning’s Leitmotif Cinema, Chinese Soft Power, and Ideological Fantasy
Authors: Green Frederik H.
Published: August 2022

This article explores the intersection of politics and popular entertainment in contemporary Chinese leitmotiv cinema (zhuxuanlü dianying), a genre that conflates political didacticism with Hollywood-style entertainment. Through my reading of three movies by Feng Xiaoning – the hero-epos Qingzang xian/A Railway in the Clouds (2006) about the building of a rail link to Tibet, the disaster movie Chaoqiang taifeng/Super Typhoon (2008) about a Chinese metropolis hit by a storm, and the war-action movie Jiawu dahaizhan/Naval Battle (2012) about the Sino-Japanese naval conflict of 1895 – I will illustrate how leitmotiv cinema negotiates demands for doctrinal orthodoxy with expectations for box-office success. Feng’s cinematic aesthetics are thus symptomatic of the discursive complexity of post-socialist Chinese Cinema where multiple temporalities and modes of production coexist in a climate of state-enforced ideological hegemony and revenue-driven market economics.
Digitalization of Special Economic Zones in China
Authors: Huang Jie
Published: August 2022

Special Economic Zones (SEZ) have become the forefront in China to test legal and technological reforms for digital trade. This chapter explores three cutting-edge case studies in China’s SEZs: the Beijing blockchain-based Single Window deposit box; newly established big data exchanges in Beijing, Tianjin, and Shanghai SEZs; and pilot projects in financial, medical care and automobile industries to flow data across the border in the Shanghai SEZ. It scrutinizes China's experiments in the context of its applications to join the Comprehensive and Progressive Trans-Pacific Partnership and the Digital Economy Partnership Agreement. It argues that the development of Chinese domestic law for digital trade is shifting away from the traditional paradigm that uses international commitments to push domestic reform or make domestic law according to international law. The development of Chinese domestic law for digital trade relies much more on China’s domestic needs than what FTAs negotiations require. FTAs are increasingly becoming a tool for China to shape international law rather than a benchmark for legislating domestic Chinese law.
A Data-Driven Analysis of Biases in the Juvenile Justice System
Authors: Sundar Ankita
Published: August 2022

Our understanding of the biases in the United States justice system has evolved over the years and the impact of these biases has become of vital importance regarding the disparities in the juvenile justice system. Juveniles entering the judicial system often face punishments and consequences for their actions that lead to long-term damage well into their adulthood. To analyze whether bias is present in the processing of juvenile defendants, I formulated three unique approaches: (1) comparing the juvenile hearing dispositions of ethnic groups to determine which group is more subject to entering the juvenile justice system, (2) comparing the ‘Department of Justice (DOJ) Criminal Justice Statistics Center for California’ data with the overall U.S. consensus and demographic population to understand the ratios of which ethnic groups out of the total population are entering the juvenile justice system, and (3) testing an Artificial Intelligence (AI) algorithm to analyze the contribution of various features (race, gender, age) in determining which juveniles are entering the juvenile justice system. Using these three approaches, I analyze how bias factors such as race, gender, and age play a critical role in disproportionate conviction of juvenile defendants. My findings also show how studies like this can provide valuable insights to ensure greater equity in the criminal justice system, leading to a fair and effective justice system providing equal treatment for all individuals irrespective of race, gender, and age.
Knowing When to Step In: Linking Teachers’ Behavioural Responses to Workplace Dissatisfaction with Intent to Leave
Authors: Pendola Andrew
Published: August 2022

As teacher shortages sweep across the United States, increasing attention has been paid to strategies for improving teacher retention. While a large body of research has focused on the dispositions and conditions that lead to teacher attrition, little attention has been paid to warning signs of teacher exits, leaving many building-level leaders without a chance to properly address the issue. In response, we aim to demonstrate how teachers behave in response to specific sources of workplace dissatisfaction, so that leaders may recognize traits of teachers who may be entering a withdrawal or exit phase. Through a mixed methods approach combining interviews with a state-representative survey of over 500 Alabama teachers, we use the Exit-V oice-Loyalty-Neglect framework to look for dissatisfaction behaviors along the ‘unfolding’ process of teacher withdrawal. We ask (1) what workplace behaviors are expressed when feeling dissatisfied in teaching, and (2) which behaviors are most closely aligned with actual intent to leave? Results demonstrate that (1) teachers mainly respond to dissatisfaction by burrowing into their work, becoming rigid to change, and limiting communication; (2) they do this most often when they feel they are stuck with conflicting expectations of their jobs; and (3) more than half actively consider leaving when bothered. This paper offers school leaders an opportunity to identify pre-exit behaviors and redirect teacher dissatisfaction towards positive retention techniques.

Authors: Yazdanipoor Forouzan , Faramarzi Hady , Bicharanlou Abdollah
Published: August 2022

The aim of this paper is to provide a map of the economy of social media platforms. We analyse digital labour on Instagram. The article asks: How are the users, who provide unpaid labour on Instagram, exploited? What kinds of labour do we find on Instagram? In doing so, the paper contributes to the literature on digital labour and the attention economy. Social media platforms exploit paid and unpaid labour in the creation and realisation of value. They capture user-generated content, transform it into commodities and sell it to companies. The article presents the results of a case study of the digital labour of Persian Internet users on Instagram. We conducted a Netnography of popular Instagram users (influencers, Internet users who make shoutouts to brands and influencers) and a survey where 600 Instagram users participated.
The Complexity of Pragmatic Competence: A Comparative Analysis of Native English Speakers’ and Turkish ESL Students’ Advice-giving Strategies
Authors: YİLMAZ Tuba
Published: August 2022

Studies revealed that English as a second language (ESL) speakers and native English speakers (NES) often used different strategies to offer advice in English. Since these differences can cause cross-cultural misunderstandings and misattribution of intent between ESL speakers and NES, it is important to identify them. For this purpose, this study analyzed the structural and pragmatic differences between the advice-giving strategies of NES and Turkish ESL speakers. 18 NES and 20 Turkish ESL students were recruited and asked to offer written advice to the given cases in a WCDT questionnaire. The analysis revealed that while the NES students tended to use the modal ‘would’, the pronoun ‘I’, and some other politeness features in their advice, Turkish ESL speakers tended to use the modal ‘should’ and the pronoun ‘you’ more. These results indicated that Turkish ESL speakers employed their pragmatic competence in Turkish to construct their discourses in English.
GRAVITY EFFECTS IN THE RETRACTION OF LIQUID FILAMENTS RESTING ON AN INCLINED PLANE

We study the retraction of liquid filaments resting on inclined solid substrates under partially wetting condition. This one causes each extreme of the filament to retract and form a region of mass accumulation (head) that subsequently develops a neck at its rear part. This neck then breaks up into a separate drop, while the rest of the filament restarts the sequence. In the horizontal case, this process is symmetric and leads to a regular arrangement of evenly spaced drops. When the substrate is inclined, gravity acts differently at each end, thus modifying the distance retracted by each end, the retraction speed and the final distance between drops, which also ceases to be uniform. We find that in the case of the inclined plane, the maximum distance retracted by the end that recedes against (in favor of) gravity decreases(increases) with respect to the horizontal case. This effect turns out to be a useful mechanism for the self–positioning of the resulting drops at the end of the process. Our experimental results, such as end positions, thickness profiles in the longitudinal section, etc., are contrasted with numerical simulations of the Navier–Stokes equations, obtaining a good agreement. This is achieved by using in the contact line the boundary condition known as Cox–Voinov–Blake (CVB)relationship, which includes both the effects of macroscopic hydrodynamics as well as molecular dynamics.

In this work, a computational model of thin film lubrication applied to a knee prosthesis was designed in order to make a comparison between three constitutive models, i.e. a power law, the Carreau-Yasuda model and the Cross model. The equivalent model of the knee prosthesis was modeled as a rigid cylinder on a deformable plane. The mechanical behavior of the deformable component representing the tibial base was assumed as a viscoelastic Standard Linear Solid(SLS). The governing equations were solved simultaneously with the determination of a free-moving boundary by implementing it in COMSOL Multiphysics software. The results obtained showed that the Cross model presents the highest shear rate value, the lowest film thickness and the dynamic viscosity with less variation along the lubrication channel, reaching a minimum viscosity value of 0.02 Pa.s. The Carreau-Yasuda model presents the highest value of friction coefficient, being 21.5 % higher than for the Power Law model and 3.67 % higher than the Cross model.

Hydraulic fracturing is a technique used to stimulate the production of conventional and unconventional hydrocarbons, being this type of resource a strategic part of Argentina’s energy reserve. The procedure consists in injecting fluids at high pressure into the wellbore to create fractures in the formation that later act as highly conductive paths through which hydrocarbons can flow. Since releasing the pressure of fracturing fluids causes the fracture to close, proppant(granular materials) is pumped together with fracturing fluids. For that reason, the way proppant is transported and deposited into the formation determines the future conductivity of the fracture. We present experimental results on the transport and settling of particles carried by water in a narrow vertical fracture scaled from typical field conditions. We discuss some basic features of the dynamics of the settlement of the proppant dune and the final placement for different types of proppant. The effect of the chosen material on the proppant transport is significant, yielding a much deeper placement of the dune when in lower density materials are used.

ПАТОГЕНЕТИЧНІ ТА ФАРМАКОЛОГІЧНІ ПРОБЛЕМИ КІСТКОВОГО ГОМЕОСТАЗУ ПРИ ОСТЕОПОРОЗІ
Authors: Kanzyuba A. I. , Stroblia V. V.
Published: August 2022

Остеопороз – системне захворювання, що характеризується погіршенням мікроархітектоніки кісток та зменшенням кісткової маси, що призводить до ризику переломів. Втрата кісткової маси, яка пов’язана з дефіцитом естрогену, часто є причиною переломів у жінок старше 50 років. Дефіцит естрогену порушує нормальний цикл кісткового гомеостазу за рахунок підвищення резорбційної активності остеокластів без відповідного збільшення активності остеобластів, що призводить до втрати кісткової тканини. Переломи призводять до інвалідності, погіршення якості життя, підвищеного ризику смертності. Через те, що ризик остеопоротичних переломів збільшується з віком, остеопороз є серйозною проблемою охорони здоров’я у всьому світі. У цьому огляді проаналізовані дані літератури відносно патогенетичних механізмів кісткового гомеостазу, вторинних факторів, що впливають на розвиток остеопорозу та застосування фармакологічних препаратів для збільшення щільності кісток і підвищення їх міцності. Оскільки остеопороз характеризується резорбцією кістки, що перевищує кісткоутворення, антирезорбтивні препарати є одним із терапевтичних варіантів при даному захворюванні. Іншим терапевтичним варіантом може бути використання анаболічних препаратів, які посилюють формування кісток. Замісна гормональна терапія не тільки запобігає втраті кісткової маси та деградації мікроархітектоніки кістки, але й значно знижує ризик переломів. Окрім того, добавки кальцію і ергокальциферол (вітамін D) залишаються важливим доповненням до фармакологічного лікування остеопорозу. В статті показано, які краще застосовувати фармакологічні варіанти лікування при остеопорозі для зменшення ризику переломів. Проаналізовані дані літератури, отримані в результаті пошуку клінічних та патогенетичних особливостей, методів діагностики і лікування остеопорозу на платформах PubMed і Google Scholar.
Intérêt des registres dans la recherche sur la douleur neuropathique
Authors: Paris P. , Pagé M.G. , Moisset X.
Published: August 2022

Les douleurs neuropathiques sont fréquentes dans la population générale et d’évolution chronique chez 7 à 10 % des adultes. Actuellement, la méthode de référence pour évaluer un traitement correspond aux essais randomisés contrôlés. Néanmoins, de telles études ne peuvent être mises en place que pour des échantillons de population limités et pendant une période déterminée. En outre, certains traitements ne pourront ainsi jamais être comparés directement, faute d’échantillons suffisamment grands et représentatifs. L’utilisation des données réelles de santé pourrait être une façon de surmonter ces difficultés. En effet, l’Association internationale d’étude de la douleur (International Association for the Study of Pain) comprend un groupe d’intérêt spécial axé sur les registres et encourageant l’utilisation de ces approches pour la douleur. Dans cette brève revue narrative, plusieurs des principaux registres de douleur chronique sont répertoriés. Les forces et les faiblesses de cette approche sont présentées. Le biais d’indication est fréquent dans les études observationnelles, car le choix du traitement est généralement influencé par les caractéristiques des patients. Cependant, un score de propension (PS) peut être utilisé pour minimiser l’impact de ces différences. L’utilisation du PS est brièvement expliquée. Certaines données spécifiques aux douleurs neuropathiques sont discutées.
Dormir ! Souffrir peut-être ! C’est toute la question
Authors: Bastuji H.
Published: August 2022

La douleur, signe d’alerte, de danger, est difficilement compatible avec l’installation du sommeil. La douleur phasique ne réveille le dormeur que dans 30 % des cas de façon transitoire, sans laisser de souvenir le matin au réveil. Les facteurs qui favorisent l’interruption du sommeil semblent impliquer la réapparition transitoire d’une connectivité cérébrale effective et d’un traitement cérébral de haut niveau. Dans la douleur chronique, des mécanismes top-down permettent à 25 % des patients de dormir correctement, et des facteurs de vulnérabilité empêcheraient ces mécanismes chez les autres.
Academic productivity in pediatric neurosurgery in relation to elective surgery slowdown during the COVID-19 pandemic

Published: August 2022

OBJECTIVE

COVID-19 has not only impacted healthcare systems directly via hospitalizations and resource utilization, but also indirectly via adaptations in healthcare practice, such as the evolution of the academic environment and the rise of telemedicine and virtual education. This void in clinical responsibilities has been filled with academic productivity in various fields. In this study the authors investigate the influence of COVID-19 on the academic focus within pediatric neurosurgery.

METHODS

All data were obtained from the Journal of Neurosurgery: Pediatrics (JNS Peds). The number of submissions for each month from January 2017 to December 2021 was collected. Data including number of publications, publication level of evidence (LOE), and COVID-19–related articles were collected and verified. Each publication was categorized by manuscript and LOE according to adaptations from the Canadian Task Force on Periodic Health Examination. Publication groups were categorized as pre–COVID-19 (January 2017–February 2020), peri–COVID-19 (March 2020–July 2020), and post–COVID-19 (August 2020–December 2021). Statistical analysis was performed to compare pre–COVID-19, peri–COVID-19, and post–COVID-19 academic volume and quality.

RESULTS

During the study time period, a total of 3116 submissions and 997 publications were identified for JNS Peds. Only 2 articles specifically related to COVID-19 and its impact on pediatric neurosurgery were identified, both published in 2021. When analyzing submission volume, a statistically significant increase was seen during the shutdown relative to pre–COVID-19 and post-shutdown time periods, and a significant decrease was seen post-shutdown relative to pre–COVID-19. LOE changed significantly as well. When comparing pre–COVID-19 versus post–COVID-19 articles, a statistically significant increase was identified only in level 4 publications. When analyzing pre–COVID-19 versus post–COVID-19 (2020) and post–COVID-19 (2021), a statistically significant decrease in level 3 and increases in levels 4 and 5 were identified during post–COVID-19 (2020), with a rebound increase in level 3 and a decrease in level 5 during post–COVID-19 (2021).

CONCLUSIONS

There was a significant increase in manuscript submission during the initial pandemic period. However, there was no change during subsequent spikes in COVID-19–related hospitalizations. Coincident with the initial surge in academic productivity, despite steady publication volume, was an inverse decline in quality as assessed by LOE.
