Social Networking Addiction and Quality of Academic Life among First-Year High School Students in Saudi Arabia: The Mediating Role of Academic Procrastination
Authors: Khalifa Ayman Gamal 
Published: August 2021

Students with high levels of procrastination were unable to organize and achieve their academic goals. A student who procrastinates may face internal consequences such as low academic performance, bad learning habits, and low learning motivation. When he/she is unable to address procrastination, this will hinder his/her academic performance. The study group of the research consists of 258 boys studying in high schools in the Riyadh region in the 2019-2020 academic year. They aged 16-18 years, (M= 17.23,SD= 4.45). Social Media Addiction Scale - Student Form, High-School Satisfaction Scale, and Tuckman's procrastination scale –short form were used for gathering and analyzing data. Quality of academic life correlates negatively with social networking addiction and academic procrastination.
On the other hand, social networking addiction was found to be positively correlated with academic procrastination. Regression coefficients of the empirical model show that social networking addiction had a direct negative effect on the quality of academic life (b= -0.49, p<0.001) and a direct positive effect on academic procrastination (b=0.52, p<0.001). Results support previous research showing that social networking addiction negatively impacts academic achievement by creating academic procrastination, reducing sleep quality, and increasing academic stress. Evidence indicates a positive and significant correlation between inappropriate and problematic use of technology and quality of academic life. Procrastination may interrupt the academic performance, as procrastinators are likely to avoid completing the task at Hand until the last moment. They may also be unable to invest the time and effort necessary for performing as they underestimate the amount of time required for completing specific tasks.

Authors: Richartz Terezinha , Lemes de Oliveira Thiago 
Published: August 2021

Em uma sociedade diversificada e cada vez mais preocupada com a equidade humana, compete ao professor uma atualização constante de seus conhecimentos, e consequentemente, ressignificação didática. Objetiva-se, neste artigo, portanto, discutir a importância da formação continuada de professores face à inclusão de um aluno surdo em sala de aula, em um curso de Pedagogia no interior de Minas Gerais, bem como, apresentar o gênero autobiográfico para se conhecer o contexto histórico do discente no intuito de identificar e desenvolver metodologias que promovam sua interação e mediação. Destina-se, ainda, relatar a experiência vivenciada por todos os sujeitos envolvidos na busca de alternativas de mediação, ensino, avaliação e por último, descrever as adaptações realizadas para respeitar a singularidade linguística do discente Surdo. A partir dessa perspectiva, o referencial teórico se pauta em autores como, Frison; Simão, Oliveira, Nacarato, Nóvoa e Foucault. A metodologia utilizada configura o relato de experiência associada à autobiografia de um aluno Surdo. Como resultado, observa-se que a formação continuada, atrelada ao trabalho em conjunto de professores e tradutor e intérprete de Libras, foi fundamental para entender demandas apresentadas a partir da especificidade do aluno surdo, além de compartilhar ações práticas e vivências de seus participantes durante esse processo.

Published: August 2021

A partir de um estudo bibliográfico, analisaram-se os itinerários e resultados de duas pesquisas de Doutorado, defendidas em 2018 e 2019 no Laboratório de Estudos e Pesquisas em Ensino e Diferença (LEPED), da Universidade Estadual de Campinas (UNICAMP). A necessidade de encontrar caminhos que possibilitam uma formação continuada de professores para uma educação inclusiva originou essas investigações. Sabe-se que a formação inicial não é suficiente para preparar os professores para o desenvolvimento de um trabalho pedagógico inclusivo, uma vez que as demandas, nesse sentido, se atualizam constantemente. Assim sendo, os objetivos deste texto foram analisar as contribuições da valorização da narratividade dos professores participantes de dois processos de formação continuada, um presencial e outro à distância, e identificar quais os pontos em comum entre os dois processos que levaram os participantes a uma reflexão e reconstrução de práticas pedagógicas a fim de incluir todos os estudantes na sala de aula comum. Concluiu-se que, em ambas as teses, a valorização da subjetividade dos professores participantes e o fundamento na Política Nacional de Educação Especial na Perspectiva da Educação Inclusiva (PNEEPEI, BRASIL, 2008) foram pontos determinantes para o entendimento dos professores sobre o que é a inclusão e suas demandas. Ao narrarem as suas experiências docentes durante as duas formações investigadas, os participantes repensaram o modo como concebiam o ensino, a aprendizagem e a deficiência e entenderam que o papel de uma escola inclusiva é o de promover a plena participação de cada aluno, mas segundo a sua capacidade, sem a pretensão de que ocorra uma homogeneização da aprendizagem.

Published: August 2021

Este texto nasce no seio das experiências formativas empreendidas na Licenciatura em Educação do Campo, da Universidade Federal do Espírito Santo, no campus de Goiabeiras/Vitória, ES. Tem como objetivo dialogar com as memórias e narrativas dos sujeitos em formação, registradas nos Cadernos da Realidade, buscando à luz destas conhecer, reconhecer e compreender os processos enredados. Investiga como o uso desses cadernos tem potencializado as aprendizagens construídas nos territórios formativos do tempo universidade e do tempo comunidade. Fundamenta-se nos estudos de Walter Benjamin (1996), em especial nas discussões sobre experiência, e produz interlocuções teóricas com autores que caminham com o Movimento Nacional da Educação do Campo e a Formação por Alternância. Como perspectiva metodológica, analisa narrativas e memórias registradas nos Cadernos da Realidade a partir das discussões de Josso (2004) e Bertaux (2010). Compreende que os Cadernos podem ser empregados como mediações didático-pedagógicas da formação por alternância, capazes de propulsarem o pensar reflexivo e problematizador da inserção comunitária dos estudantes, do desenvolvimento profissional docente no campo e, ainda, da própria trajetória dos sujeitos na licenciatura em Educação do Campo.
Effects of Changing Anticoagulation with Unfractionated Heparin into Enoxaparin in Hemodialysis Patients:Prospective Non Randomized Unicentre Study

Published: August 2021

Background: Maintaining the patency of the extracorporeal circuit (ECC) is required. The cost and long-term effect of anticoagulants on hemodialysis (HD) patients' parameters are still matters of concern. We aimed to study the effect of shifting to enoxaparin instead of unfractionated heparin (UFH) during HD and evaluate its efficacy, safety, and benefits.
Design and methodology: This study was conducted at Arar hospital, Kingdom of Saudi Arabia (KSA), and included 86 end-stage renal disease (ESRD) patients on HD for six months starting from October 2017. All patients had been on UFH as an anticoagulant during hemodialysis sessions before they were shifted to equivalent doses of enoxaparin sodium (Clexan®) as a therapeutic upgrade to start with. The patients’ files were examined retrospectively for the period of UFH therapy and then all patients were observed prospectively for at least 6 months while on Clexane. The occurrence of clotting in the dialysis sets were recorded and the need for urgent HD for each patient and the reasons.
Results: There was a reduction of filter clots even with the reduction of enoxaparin dose. There was a significant reduction of mean cholesterol, calcium, phosphorus, sodium, chloride, and serum osmolality. We found a significant reduction of pre-dialysis potassium among those who presented with a pre-dialysis potassium of higher than 5.5 mg/dl during the enoxaparin phase. Patients, who had thrombocytopenia while on UFH; showed improvement in platelet count after the shift to enoxaparin. However, patients who had platelet count lowered than 150000/mm3 6 months after having been shifted to enoxaparin; many of them received HD through a permanent catheter. No patients had a three-fold increase of normal values (3ULN) of liver function tests whether being on heparin or enoxaparin.
Conclusion: Low molecular weight heparin (LMWH) could be more efficacious and safe than UFH with the improvement of some variables in HD patients.

Gompertz Rayleigh (GomR) distribution was introduced in an earlier study with few statistical properties derived and parameters estimated using only the most common traditional method, Maximum Likelihood Estimation (MLE). This paper aimed at deriving more statistical properties of the GomR distribution, estimating the three unknown parameters via a competitive method, Maximum Product of Spacing (MPS) and evaluating goodness of fit using rainfall data sets from Nigeria, Malaysia and Argentina.
Properties of statistical distributions including distribution of smallest and largest order statistics, cumulative or integrated hazard function, odds function, rth non-central moments, moment generating function, mean, variance and entropy measures for GomR distribution were explicitly derived. The fitted data sets reveal the flexibility of GomR distribution over other distributions been compared with. Simulation study was used to evaluate the consistency, accuracy and unbiasedness of the GomR distribution parameter estimates obtained from the method of MPS. The study found that GomR distribution could not provide a better fit for Argentine rainfall data but it was the best distribution for the rainfall data sets from Nigeria and Malaysia in comparison with the distributions; Generalized Weibull Rayleigh (GWR), Exponentiated Weibull Rayleigh (EWR), Type (II) Topp Leone Generalized Inverse Rayleigh (TIITLGIR), Kumarawamy Exponential Inverse Raylrigh (KEIR), Negative Binomial Marshall-Olkin Rayleigh (NBMOR) and Exponentiated Weibull (EW). Furthermore, the estimates from MPSE were consistent as the sample size increases but not as efficient as those from MLE.

Global Dimensional Mathematics
Authors: Denis Olivier 
Published: August 2021

Here we build the fundamentals of global dimensional mathematics in order to build the new basis of the new theoretical scientific paradigm.
Research on the foundations of mathematics covering the definition of fundamental mathematical concepts such as point, line, direction, dimension, addition, multiplication, division, zeros, infinities, limits, factorization, integers and prime numbers, were carried out and further still the resolution of the Goldbach conjecture is now effective.
New original fundamental mathematical notions are established building the core of global dimensional mathematics based on the decomposition of integers into an addition of prime numbers terms and on fundamental geometric concepts such as the concept dimension based on the notion of direction and point, as well as research on set theory and work on the notion of limits and infinity.
The termization as a decomposition of integers into an addition of prime number terms by a python program, breaks the unique factorization theorem, the fundamental theorem of arithmetic while the geometric notions developed break Euclidean geometry leading to a new mathematical framework, geometry, topology and metrics leading to a total change of theoretical scientific paradigm.
Global dimensional mathematics forms the basis for the construction of the new scientific paradigm of the 21st century and beyond, opening up a still unknown perspective on the world of science in general.

Published: August 2021

AbstractHydrogel‐based soft electronics (HSE) is promising as implantable devices due to the similarity of hydrogel substrates to biologic tissues. Most existing HSE devices are based on conducting hydrogels that usually have weak mechanical properties, low conductivity, and poor patternability. Reported here is an HSE with good mechanical performance, high sensitivity, and versatile functions by stencil printing of liquid metal on a tough hydrogel, facilitating integration of multiple sensing units. Self‐shaping ability is imparted to the HSE by creating gradient structure in the hydrogel substrate. The resultant HSE actively deforms into 3D configurations with zero or nonzero Gaussian curvature to fix on objects or organs with sophisticated geometries and maintains the sensing functions. The versatilities and potential applications of this HSE are demonstrated by monitoring motions of a rice field eel and beatings of a rabbit heart. Such HSE based on morphing substrate should pave the way for implantable electronics with better fixation and interfacial contact with the organs. The concept of morphing hydrogel devices can be extended to other soft electronics with responsive polymer films or elastomers as the substrates.

Published: August 2021

AbstractTraditional drug delivery routes possess various disadvantages which make them unsuitable for certain population groups, or indeed unsuitable for drugs with certain physicochemical properties. As a result, a variety of alternative drug delivery routes have been explored in recent decades, including transdermal drug delivery. One of the most promising novel transdermal drug delivery technologies is a microarray patch (MAP), which can bypass the outermost skin barrier and deliver drugs directly into the viable epidermis and dermis. Unlike traditional MAPs which release loaded cargo simultaneously upon insertion into the skin, stimuli responsive MAPs based on biological stimuli are able to precisely release the drug in response to the need for additional doses. Thus, smart MAPs that are only responsive to certain external stimuli are highly desirable, as they provide safer and more efficient drug delivery. In addition to drug delivery, they can also be used for biological monitoring, which further expands their applications.

Published: August 2021

AbstractElectrocatalytic oxygen evolution reaction (OER) plays a key role in sustainable energy conversion and storage, but is severely hampered by the lack of efficient catalysts, whose development remains a critical and challenging issue. Herein, it is reported for the first time that pure and Fe2O3‐containing Co3O4‐based OER electrocatalysts are grown on highly porous Ni foams by plasma enhanced‐chemical vapor deposition and/or radiofrequency sputtering. Thanks to the inherent advantages of cold plasma synthesis routes, Ni foam supports are efficiently infiltrated by Co3O4 nanostructures and eventually nanosized Fe2O3, allowing a fine‐tuning of their mutual content, nano‐organization, and oxygen defectivity. For Co3O4‐Fe2O3 systems, these issues enable current densities up to ≈120 mA cm−2 at 1.79 V versus the reversible hydrogen electrode, an overpotential of ≈350 mV at 10 mA cm−2 and a Tafel slope as low as 60 mV dec−1, favorably comparing with literature values for most cobalt‐based OER catalysts reported so far. Such features, accompanied by a good time stability, represent an important goal for eventual practical applications and candidate the proposed fabrication route as a valuable tool for the design of efficient electrocatalysts with precisely engineered properties and based on naturally abundant transition elements.
Preparation of Quasi‐Thermoplastic Phase Change Polymer with Intrinsic Antileakage Performance for Battery Thermal Management

Published: August 2021

AbstractPhase change material (PCM) shows great potentials in battery thermal management (BTM) application, but there are significant challenges including PCM leakage, low secondary heat dissipation capability, and poor reprocessability. Herein, a type of phase change polymer (PCP) with intrinsic antileakage, reprocessability and heat dissipation capability is prepared via the copolymerization of octadecyl acrylate (OA) and methyl methacrylate (MMA). The rigid segment of MMA guarantees the shape stability of the PCP while avoiding using the crosslinkers, and thus simultaneously endows the linear PCP with quasi‐thermoplastic property for reprocessing. The chemical‐bonded phase changeable side chains from the OA segments provide a large latent heat of 100.5 J g–1 and fundamentally overcome the leakage problem. Additionally, the obtained PCP demonstrates a higher crystalline temperature favorable for secondary dissipation of the absorbed heat to the environment. Consequently, the obtained PCP demonstrates superior cooling performances in BTM applications. The temperature of the battery module with PCP cooling can be stably controlled below 52.5 °C under a harsh working environment of 3C‐3C charge–discharge at 35 °C for 15 cycles. In contrast, the battery module adopting classical physically blended PCM cooling shows a much higher and gradually increasing maximum temperature during the cycles.
Manipulating Second Harmonic Generation in Higher‐Order Topological Photonic Crystals

Published: August 2021

AbstractHigher‐order topological photonic crystals (TPCs) have attracted much attention in the past several years since they do not obey the conventional bulk‐boundary correspondence in topological insulating phases. This characteristic offers a new dimension with which to trap and manipulate the flow of light. In this work, 2D higher‐order TPCs for engineering optical second harmonic generation (SHG) are designed. In the TPCs, a topological corner‐state is achieved and it is demonstrated that the high localization of photons at the corner‐state can significantly promote optical SHG. In addition, topological edge‐states are obtained by breaking the Dirac degeneracy point near the SHG frequency. They are also topologically protected and immune to bending resistance. Therefore, the enhanced SHG signal from the corner‐state can be manipulated precisely for transmitting through the designed interface with relatively low loss due to the topological‐protection edge waves. This design strategy combines the advantages of corner‐state and edge‐state in higher‐order TPCs, demonstrating potential applications of topological photonic devices, such as optical communication and optical computing technologies.
