The study aimed to examine how emotional design and digitalization/mobilization of textbooks influence students’ emotion, cognitive load, and cognitive performance. Research samples were 147 undergraduate students enrolling in the “Introduction to Internet” course at a university. They were randomly divided into three groups: 51 students in the control group using traditional paper textbooks;49 students in the experimental group I using e-textbooks with emotional design;47 students in the experimental group II consisted using e-textbooks without emotional design. The MANCOVA was adopted to analyze gathered data. The results revealed learners’ positive emotion was significantly higher when using e-textbooks with emotional design than when using paper textbooks. Three types of cognitive load was significantly better when using e-textbooks with emotional design than when using e-textbooks without emotional design and paper textbooks. Cognitive efficiency was significantly better when using two types of e-textbooks (with and without emotional design) than when using paper textbooks. In a word, “emotional design and digitalization/mobilization” of textbooks (i.e. e-textbooks with emotional design) would significantly improve positive emotion;emotional design would significantly decrease intrinsic and extraneous cognitive load when using e-textbooks, and significantly increase germane cognitive load;digitalization/mobilization of textbooks (i.e. e-textbooks) significantly improved cognitive efficiency. What the study learned was that learners might firstly adopt e-textbooks with emotional design, and those without emotional design secondly, and paper textbooks rank last;viz., digitalized/mobilized textbooks (namely e-textbooks) were better than paper textbooks. Practical and theoretical implications and suggestions were raised for practitioners and researchers to take as references. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, pa

This study aims to explore how e-textbooks with emotional design affect students' emotion, cognitive load and learning achievement. There were 147 freshman students in total: the experimental group I, II and control group consisted of 49, 47 and 51 students, using e-textbooks with emotional design, without emotional design and traditional paper textbooks. The results reveal the following: Students' emotion after using e-textbooks with emotional design is more positive than those using e-textbooks without emotional design and paper textbooks. Students' cognitive load after using e-textbooks with emotional design is significantly lower than those using etextbooks without emotional design. Students' learning achievement after using two types of e-textbooks is better than after using paper textbooks. Comparing all types of textbooks altogether, emotion has a significantly positive correlation with learning achievement, and both emotion and learnng achievement are significantly and negatively correlated with cognitive load. For the three types of textbooks, the relationship between emotion and learning achievement all becomes not significantly correlated. For two types of e-textbooks, cognitive load and learning achievement become not significantly correlated, disturbed by the digitalization of textbooks. Instructors are suggested to firstly adopt e-textbooks with emotional design, those without emotional design secondly, and paper textbooks rank last. © 2022 Informa UK Limited, trading as Taylor & Francis Group.

The purpose of the study is to investigate the effects of different combined annotations with first and second languages for verbal annotations and pictures and animation for visual annotations. It was administered on PDAs to further confirm whether the results are in agreement with those implemented on the desktop. According to the assigned annotation type, four classes of 121 senior high school freshmen in central Taiwan read 4 passages, each of which had 5 target English verbs, annotated in the following ways: L1 definition-plus-graphics, L1 definition-plus-animation, L2 definition-plus- graphics, and L2 definition-plus-animation. These participants took an immediate posttest after reading each and a delayed parallel posttest one month after the experiment. Two-way ANOVA analyses indicated no significant differences between the definition languages but significant differences between the visual aids, with animation more effective;besides, no interaction effects were observed. The findings of definition languages were in line with the previous studies', and this study offered evidence from younger adults and lower proficient English learners. The performance for animation over pictures supported the argument that dynamic animation is designed to illustrate concepts of changes and processes such as English verbs. Directions for future research and suggestions for language practitioners are also discussed.

The on-going energy crisis and environmental pollution have motivated the scientific community to develop a sustainable energy technology. The energy storage is one of the main focus areas in this development process and supercapacitors are gaining significant research importance on that context. The electrode material of a supercapacitor plays a crucial role in its charge storage capability. Fe–S based materials are cheap owing to their high natural abundance and shows high specific capacitance value. One-pot hydrothermal reaction is the widely used procedure for synthesizing transition metal sulfides;however, there exists the possibility of impurity formation in this process. The Fe2+ and Fe3+ salts are the common precursors of Fe and two extensively utilized S-sources are Na2S and thiourea. Four different iron pyrite samples were synthesized by varying the reaction precursor and this variation regulated the phase purity and morphology of the final product. The combination of Fe2+ and thiourea was more suitable for synthesizing pure FeS2 and little to higher amount of Fex−1Sx impurity was formed in other three cases. The charge transfer and ion diffusivity of FeS2 decreased with the incorporation of Fex−1Sx, which diminished its specific capacitance. The superiorly active pyrite-based electrode material achieved ~ 1142 F g−1 at a current density of 2 A g−1. This investigation revealed the necessity of choosing accurate precursors for synthesizing electrode material through a one-pot hydrothermal reaction. © 2021, The Institution of Engineers (India).

The effects of the PCM-based cold storage system operated under periodic (P12) and continuous (P24) storage conditions on the physico-chemical characteristics of mango fruits were investigated. Fruits in P12 and P24 storage conditions underwent weight loss, peel colour change, soluble solid concentration and maintained high firmness, titratable acidity and ascorbic acid along with the conventional cold storage system (G24). Temperature response and energy consumption revealed that PCM-based cold storage conditions P12 and P24 maintain the temperature within the permissible range and consume less energy than the conventional system. An effective reduction of 39 and 18% of energy consumption was noticed in P12 and P24 PCM-based cold storage conditions. As per these results periodic PCM-based cold storage (P12) can be effectively used as an energy-saving cold storage technology alternative to a conventional cold storage system to maintain the mango fruit quality during power failure and off-peak load conditions. © 2022 Informa UK Limited, trading as Taylor & Francis Group.

Meditation is a family of ancient and contemporary contemplative mind-body practices that can modulate psychological processes, awareness, and mental states. Over the last 40 years, clinical science has manualized meditation practices and designed various meditation interventions that have shown therapeutic efficacy for disorders including depression, pain, addiction, and anxiety. Over the past decade, neuroimaging has been used to examine the neuroscientific basis of meditation practices, effects, states, and outcomes for clinical and nonclinical populations. However, the generalizability and replicability of current neuroscientific models of meditation have not yet been established, because they are largely based on small datasets entrenched with heterogeneity along several domains of meditation (e.g., practice types, meditation experience, clinical disorder targeted), experimental design, and neuroimaging methods (e.g., preprocessing, analysis, task-based, resting-state, structural magnetic resonance imaging). These limitations have precluded a nuanced and rigorous neuroscientific phenotyping of meditation practices and their potential benefits. Here, we present ENIGMA (Enhancing Neuro Imaging Genetics through Meta Analysis)–Meditation, the first worldwide collaborative consortium for neuroscientific investigations of meditation practices. ENIGMA-Meditation will enable systematic meta- and mega-analyses of globally distributed neuroimaging datasets of meditation using shared, standardized neuroimaging methods and tools to improve statistical power and generalizability. Through this powerful collaborative framework, existing neuroscientific accounts of meditation practices can be extended to generate novel and rigorous neuroscientific insights that account for multidomain heterogeneity. ENIGMA-Meditation will inform neuroscientific mechanisms that underlie therapeutic action of meditation practices on psychological and cognitive attributes, thereby advancing the f

Background: Sustainable development Goal 2 aims at ending hunger, achieving food security, improving nutrition and promoting sustainable agriculture. Whilst some smallholder farmers are aware of this goal, others are not. The question that arises is whether or not awareness translates into food security. Therefore, this study assessed whether or not smallholder farmers’ awareness of Sustainable development Goal 2 improves household food security in the Northern Region of Ghana. Methods: The study used cross-sectional primary data collected from two districts and two municipalities in the region. An endogenous switching regression treatment effects model with ordered outcome was used to estimate the effects of smallholder farmers’ awareness of Sustainable development Goal 2 on household food insecurity level. Results: The age of household head, distance of households to the regional capital, membership of farmer-based organizations, access to e-extension, education, and ownership of radio are the key drivers of farmers’ awareness of Sustainable development Goal 2. The results from the endogenous switching regression treatment effects model with ordered outcome showed that households who are aware of the second goal are more food secure than their counterparts. Conclusions: It is therefore prudent for stakeholders promoting and championing Sustainable development Goals to educate farmers on goal 2 as their awareness of the goal is critical to achieving food security. © 2021, The Author(s).

This study integrated Chinese, Geography, and computer science courses, with teachers from those disciplines collaborating to prepare their courses. The study employed mobile devices in the learning activities, used the situated learning strategy, and involved the students in real-life investigation in the interdisciplinary literacy curriculum. The students observed, learning in the real-life environment, and utilized mobile technologies to support their data collection and information searching. The students made connections between the knowledge in the textbook and the real-life situation in the literacy-based learning activities. After they came back to the classroom, they used the data and photos they had collected to design the virtual reality of the environment they had visited in order to recall and reflect on the activity. This study primarily explored the learning effectiveness of Chinese, and found that the students made significant progress. However, from the investigation of motivation, it was found that the students did not prefer to practicing writing based on the virtual reality situation in comparison with the real-life situation. © 2018 Asia-Pacific Society for Computers in Education..All Rights Reserved.
