Published: August 2023

This research discusses a concept in which the consequences of one's actions are immediate rather than borne out over a lifetime in Instant Karma! by John Lennon. This descriptive qualitative research focuses to find out how does karma associate with the world anthem against the evil portrayed in John Lennon’s song lyrics Instant Karma!, from the Psychoanalytic theory by Sigmund Freud. The song title is Instant Karma! itself is an implementation of a concept of accountability for your actions. Therefore, the view of the psychoanalytic put forward by Sigmund Freud (1901) is compatible to analyze Instant Karma! by John Lennon. Data were collected by studying, interpreting works of literature, and evaluating them. Studying means getting a better understanding of the song through close readings of the lyrics, contextual insights, and listening to it. Interpreting means trying to find the meaning or theme of the song through related interviews with John Lennon as the writer, composer, and singer. Analyzing through song lyrics was the only way to be done since there was no music video. Evaluating means giving criticism about the song lyrics themselves. Criticism is not all about finding fault or any mistakes, but about how we interpret the meaning of the song itself. The data was collected together one by one through the note-taking approach to discover the data to associate with valid information related. The conclusion shows Instant Karma! by John Lennon portrays the outcome of a person’s actions in past and present states of existence. Those actions lead us to our fate. What comes around, goes around, what we sow, so shall we reap. The Karma itself is not only associated with bad output but also as a good one. Good deeds will have a positive effect while bad deeds will bring negative consequences
Rethinking digital activism
Authors: Blaagaard Bolette , Roslyng Mette Marie 
Published: August 2023

This article explores the following research question: How is political activism expressed in connective, affective, and embodied ways, and how do these modes result in a rearticulation of the body and central activist signifiers? While connective and affective dimensions of digital activism offer invaluable insights into the new forms of activist organisation, it remains underexplored how the activist body and the concepts of “human” and “rights” are discursively produced through digital expressions of activism. Therefore, drawing on a purposive selection of digital content, we produce a discursive analysis of three illustrative cases of digital activism relating to three major political contemporary issues: Black Lives Matter, #MeToo, and Extinction Rebellion. We argue that they each present different modes of embodied and discursively constructed signifiers of “human” and “rights”, which allows for a range of political aims and outcomes to be expressed through different degrees of antagonism calling, respectively, for deconstruction, inclusion, and expansion of the signifiers.
Fundamentação epistemológica do paradigma da complexidade e a dialogia com a formação de professores
Authors: Lima Paulo Gomes 
Published: August 2023

O objetivo deste artigo é o de discutir a fundamentação epistemológica do paradigma da complexidade, a partir da contribuição de Edgar Morin e a dialogia com a formação de professores. Esta perspectiva defende que o ser (homem) e o saber (conhecimento) são elementos inseparáveis que possuem estruturas complexas multidimensionais que se ligam e religam de forma holística (físico, biológico, cerebral, mental, psicológico, cultural, social), isto é, “sem excluir aquele que conhece de seu próprio conhecimento.” O objetivo maior de Edgar Morin, ao propor o paradigma da complexidade é chamar a atenção para a necessidade de mudança de perspectiva de um mundo que “vive” e “vê” o real de forma fragmentada, dissociando as partes do todo como se fossem elementos independentes. Nessa diretriz a dialogia com a formação de professores, além de possível, encampa o compromisso de entender e viver a educação como fenômeno multidimensional que não dissocia os sujeitos de suas formas de intervenção no real.
Optimation of Energy Efficiency by Integrated Design of Folding Wall-BIPV and Users Behaviour in Office Building at Surabaya
Authors: Susan  , Ngurah Antaryama I Gusti 
Published: August 2023

AbstractEfficiency of BIPV measured by comparing electricity output and electricity demand. Electricity output generized by BIPV depends on the amount of solar radiation received by PV panel. Some factors that affect the amount of radiation received are the tilt angle and the orientation angle of PV panel. This research try to rise electricity output by collaborating this factor with orientation principle in folding concept. The collaboration results in bigger surface area to receive radiation. Meanwhile, the reducement of electricity demand will be described in relation with users behaviour, both individual behaviour and communal behaviour. As the object taken in this research is an office building, communal behaviour will take more impact to reduce energy demand. Policies and strategies related to energy efficiency made by central operational management in office building will control communal behaviour.
An Analysis of Students’ Perspectives on the Usage of Knowledge Maps in Open Learning Environments
Authors: Fasihuddin Heba , Skinner Geoff 
Published: August 2023

AbstractOpen learning is a new form of online learning that allows learning materials and courses to be freely available on the Internet and accessible to anyone who is interested. Massive Open Online Courses is the term used for courses provided in these open environments. The authors believe that open learning environments are still in their early stages of evolution in terms of providing effective learning models with many aspects still needing to be considered. These aspects can be addressed with consideration to principles of cognitive science and herein lies our research. Based on the concept of schema theory, the knowledge map has been chosen to organize and present learning concepts. This paper presents a study that has been held to evaluate the use of knowledge maps as an approach to presenting and organizing learning materials in open learning environments. A prototype has been developed and piloted on a group of IT students. The students’ perspectives on the use of the knowledge maps and how they affect their learning have been collected through two surveys. The result is promising and an indication of the likely success of such an approach.
Automatic and Semi-Automatic Test Generation for Introductory Linguistics Courses Using Natural Language Processing Resources and Text Corpora
Authors: Wood Peter 
Published: August 2023

AbstractThis paper describes a collection of Natural Language Processing (NLP) modules which automatically generate exercises for introductory courses on structural linguistics and English grammar at a Canadian University.While there is a growing demand for electronic exercises, online testing tools, and self contained linguistics and grammar courses, the exercises and tests offered on companion websites for popular textbooks consist largely of multiple choice type questions.The modules create exercises to practice and test part-of-speech identification, morphological analysis of complex words, and the analysis of sentences into phrase structure trees. They are part of an infrastructure capable of delivering instructional material, exercises for for self assessment, and online testing tools for courses which either use blended instruction or are taught exclusively online.Modules which are work in progress will be briefly discussed in the final section of this paper.

Published: August 2023

ImportanceOne in 5 US adults older than 60 years takes fish oil supplements often for heart health despite multiple randomized clinical trials showing no data for cardiovascular benefit for supplement-range doses. Statements on the supplement labels may influence consumer beliefs about health benefits.ObjectivesTo evaluate health claims made on the labels of fish oil supplements in the US, and to examine doses of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in commonly available formulations.Design, Setting, and ParticipantsThis cross-sectional study used data from labels of on-market fish oil (and nonfish ω-3 fatty acid) supplements obtained from the National Institutes of Health Dietary Supplement Label Database. The study was conducted and data analyzed from February to June 2022.Main Outcome and MeasuresThe frequency and types of health claims made on fish oil labels (US Food and Drug Administration [FDA]–reviewed qualified health claim vs a structure/function claim) and the organ system referenced were evaluated. The total daily doses of combined EPA and DHA (EPA+DHA) were assessed for supplements from 16 leading manufacturers and retailers.ResultsAcross 2819 unique fish oil supplements, 2082 (73.9%) made at least 1 health claim. Of these, only 399 (19.2%) used an FDA-approved qualified health claim; the rest (1683 [80.8%]) made only structure/function claims (eg, “promotes heart health”). Cardiovascular health claims were the most common (1747 [62.0%]). Across 16 leading brands/manufacturers, 255 fish oil supplements were identified. Among these, substantial variability was found in the daily dose of EPA (median [IQR], 340 [135-647] mg/d), DHA (median [IQR], 270 [140-500] mg/d), and total EPA+DHA (median [IQR], 600 [300-1100] mg/d). Only 24 of 255 supplements (9.4%) evaluated contained a daily dose of 2 g or more EPA+DHA.ConclusionsResults of this cross-sectional study suggest that the majority of fish oil supplement labels make health claims, usually in the form of structure/function claims, that imply a health benefit across a variety of organ systems despite a lack of trial data showing efficacy. Significant heterogeneity exists in the daily dose of EPA+DHA in available supplements, leading to potential variability in safety and efficacy between supplements. Increasing regulation of dietary supplement labeling may be needed to prevent consumer misinformation.

ImportanceOlder adults with atopic dermatitis (AD) face unique treatment challenges, including comorbidities, polypharmacy, and a higher risk for infections (eg, herpes zoster). Furthermore, limited data are available from clinical trials for treatments in this population. In phase 3 studies, tralokinumab showed superior efficacy in moderate-to-severe AD vs placebo, but results were not stratified by age group.ObjectiveTo evaluate the safety and efficacy of tralokinumab in older (≥65 years) patients with moderate-to-severe AD.Design, Setting, and ParticipantsA post hoc analysis for adults 65 years or older was conducted from a subset of patients in the US, Canada, Europe, and Asia in 3 randomized, placebo-controlled, phase 3 trials (ECZTRA 1 and 2 [monotherapy] and ECZTRA 3 [tralokinumab + topical corticosteroids as needed]). The post hoc data were analyzed in 2022.Main Outcomes and MeasuresPooled data from up to 16 weeks of treatment from ECZTRA 1, 2, and 3 were used to assess safety. Statistical analyses followed prespecifications of primary end points. Separate efficacy analyses were conducted in these trials respectively at 16 weeks.ResultsA total of 75 older adults (42 women [56%]) treated with tralokinumab from the ECZTRA 1, 2, and 3 trials were included in this post hoc analysis. Similar proportions of patients reported adverse events (AEs) with tralokinumab and placebo (44 [58%]). Three patients (4%) in the tralokinumab arm and 3 (10.3%) in the placebo arm experienced severe AEs, and 4 (5.3%) and 2 (6.9%), respectively, had AEs leading to discontinuation. More patients achieved 75% or greater improvement in Eczema Area and Severity Index scores with tralokinumab than placebo (33.9% vs 4.8%; P &amp;lt; .001) in ECZTRA 1 and 2. Similar trends, although not statistically significant, were seen in ECZTRA 3. Safety and efficacy outcomes in this population were similar compared with the younger patient cohorts. The small sample size limited generalizations from this analysis.Conclusion and RelevanceThe results of this post hoc analysis suggest that tralokinumab is well tolerated and efficacious in patients 65 years or older with moderate-to-severe AD.

Published: August 2023

AbstractWearable electronics have impacted many aspects of human life including health monitoring, disease diagnosis, and human‐machine interfacing. However, the rapid development also accelerates the generation of electronic waste (e‐waste), which is threatening the health of ecological systems. Accordingly, high‐performance biodegradable materials suitable for transient electronics are highly demanded and challenging. In this work, a fully biodegradable and biocompatible ionotronic skin is designed based on double‐network natural polyelectrolytes derivatives. It consists of carboxylated chitosan (CCS) and sulfobetaine methacrylate (SBMA) polymerized in glycerol and water followed by cross‐linking with hydrogen bonds and electrostatic attraction (namely SBMAX‐CCSY‐Glyz). By macromolecular engineering, the ionotronic skin exhibits high ionic conductivity, good compliance with skin, as well as complete degradability, which is capable of transient measurement of electrophysiology. Applied on the sciatic nerve of bullfrog, it can accurately record action potentials and fully degrade in only 3 days without any residue. Such biodegradable and biocompatible ionotronic skin will shed light on the design of ionotronic materials for future transient electronics.

Published: August 2023

AbstractAs a promising candidate for next‐generation nonvolatile memory devices, ferroelectric oxide films exhibit many emergent phenomena with functional applications, making understanding polarization switching and domain evolution behaviors of fundamental importance. However, tracking domain wall motion in ferroelectric oxide films with high spatial resolution remains challenging. Here, an in situ biasing approach for direct atomic‐scale observations of domain nucleation and sideways motion is presented. By accurately controlling the applied electric field, the lateral translational speed of the domain wall can decrease to less than 2.2 Å s−1, which is observable with atomic resolution STEM imaging. In situ observations on a capacitor structured PbZr0.1Ti0.9O3/La0.7Sr0.3MnO3 heterojunction demonstrate the unique creeping behavior of a domain wall under a critical electric field, with the atomic structure of the creeping domain wall revealed. Moreover, the evolution of the metastable domain wall forms an elongated morphology, which contains a large proportion of charged segments. Phase‐field simulations unveil the competition between gradient, elastic, and electrostatic energies that decide this unique domain wall creeping and morphology variation. This work paves the way toward a complete fundamental understanding of domain wall physics and potential modulations of domain wall properties in real devices.

Published: August 2023

AbstractDue to the relatively inferior dielectric constant, Sn‐based perovskites exhibit lower defect tolerance and insufficient dielectric shielding effect compared with Pb‐perovskites. Upgrading built‐in electric field (BEF) in Sn‐based perovskite solar cells (PSCs) can be effective to reduce large voltage deficit and improve poor performance caused by the low defect tolerance resulting from the intrinsic inferior dielectric of Sn‐based perovskites. Herein, 2‐methylbenzimidazole (MBI) molecular ferroelectric with low coercive field and high Curie‐temperature is introduced to construct an additional ferroelectric field in FASnI3‐based PSCs. The ferroelectric effect of MBI can promote exciton dissociation, enhance carrier population, and suppress the adverse effect of the residual defects on carriers, and the directional polarization of MBI in FASnI3 film can be driven by the BEF in PSCs to broaden the width of depletion region. Additionally, the MBI molecules with amine functional groups effectively regulate perovskite crystallization, passivate Sn‐related defects, and enhance the oxidation barrier. Profiting from the above advantages, the MBI‐modified device achieves a champion power conversion efficiency (PCE) of 12.91%, keeping over 94% average PCE after 1056 h in N2 glovebox for the unencapsulated device. This study highlights the significant role of molecular ferroelectrics in perovskite photovoltaics.

AbstractFerromagnetic materials with a strong spin‐orbit coupling (SOC) have attracted much attention in recent years because of their exotic properties and potential applications in energy‐efficient spintronics. However, such materials are scarce in nature. Here, a proximity‐induced paramagnetic to ferromagnetic transition for the heavy transition metal oxide CaRuO3 in (001)‐(LaMnO3/CaRuO3) superlattices is reported. Anomalous Hall effect is observed in the temperature range up to 180 K. Maximal anomalous Hall conductivity and anomalous Hall angle are as large as ∼15 Ω−1 cm−1 and ∼0.93%, respectively, by one to two orders of magnitude larger than those of the typical 3d ferromagnetic oxides such as La0.67Sr0.33MnO3. Density functional theory calculations indicate the existence of avoid band crossings in the electronic band structure of the ferromagnetic CRO layer, which enhances Berry curvature thus strong anomalous Hall effects. Further evidences from polarized neutron reflectometry show that the CaRuO3 layers are in a fully ferromagnetic state (∼0.8 μB/Ru), in sharp contrast to the proximity‐induced canted antiferromagnetic state in 5d oxides SrIrO3 and CaIrO3 (∼0.1 μB/Ir). More than that, the magnetic anisotropy of the (001)‐(LaMnO3/CaRuO3) superlattices is eightfold symmetric, showing potential applications in the technology of multistate data storage.

AbstractFurther commercialization of Ni‐rich layered cathodes is hindered by severe structure/interface degradation and kinetic hindrance that occur during electrochemical operation, which leads to safety risks and reduced range in electric vehicles (EVs). Herein, by selecting elements with different solubility properties, a multifunctional strategy that synchronously fabricates perovskite‐type SrZrO3 coating and Sr/Zr co‐doping is employed to strengthen the structure/interface stability and the Li+ transport mobility of LiNi0.85Co0.10Mn0.05O2 (NCM). Perovskite‐type SrZrO3 protective layers formed on the particle surface can substantially mitigate the unexpected interfacial side reactions and surface phase transitions. In addition, a robust crystal framework is constructed by optimizing local O coordination through the introduction of strong Zr−O bonds. Notably, Li+ diffusion kinetics is effectively improved due to expanded cell parameters and O‐Li‐O slab spacing with the incorporation of large‐diameter Sr pillar ions, as revealed by X‐ray diffraction. As a result, the Sr/Zr‐modified NCM achieves a remarkable capacity retention of 99.4% after 200 cycles at 1 C, and a high rate capacity of 168.9 mAh g−1 at 10 C. This work opens new avenues to develop high‐performance NCM cathodes with high energy and high power for EVs with long calendar life.
