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.

With the growing pursuit of leisure and health in life, the goods and services of the traditional beauty industry produce a great impact due to the aromatherapy has different levels of approach to cosmetology and health protection. In response to the typical industrial styles of aesthetic economy and experience economy times, Spa industry not only requires high-quality service system, but also relies on the aromatherapist to provide the skills of cure for body and soul. The professional performance of aromatherapist is the core competence for establishing the brand image. It is different from the traditional beauty industry which is performanc-eoriented for job performance. aromatherapist must bear a high degree of physical and mental labor. In addition to providing technical services, they also have to meet the customers' demands for the knowledge of commodities in a consultative way. Behind these reasons, the higher work threshold, adaptation and movement of persons have become the major problems for the Spa industry. This research discusses the diversity of organizational commitment of aromatherapist with different background, and analyses the relationships among their organizational commitment and job performance. The presented result may serve as a reference for aromatherapy organization in developing human resource management and development. The population of research is the Spa aromatherapist in Taipei city. Of the 300 questionnaires the researcher took out 198 responded which is with the response rate of 66%. All the data for this research was analyzed by using the methods of t-test, product-moment correlation, and multiple regression analyses. The results indicate that there is a significant relationship between the aspects of organizational commitment and job performance for aromatherapist. The degrees of organizational commitment of aromatherapist whose ages up to 31 is higher than the age less than 30 has significant difference in the aspects of retenti

Journal of Environmental Management 2025年 387卷 125865页

作者： Mensah, Philip Opoku Yong, Jing Yi Dura, Codruța Cornelia Mensah, Henry Kofi University of Strathclyde Department of Work Employment and Organisation Scotland United Kingdom School of Management and Marketing Faculty of Business and Law Taylor's University Malaysia University of Petroşani Department of Economics Romania University of Oradea Doctoral School of Economic Sciences Romania Kwame Nkrumah University of Science and Technology Department of Human Resource and Organisational Development Ghana

This study explores the influence of Green human resource Management Strategy (GHRMS) on supply chain environmental sustainability in manufacturing SMEs, emphasising the mediating role of green dynamic capability and the moderating effect of institutional networking capability. Quantitative data was gathered from 263 owners and managers in Ghana's manufacturing sector. The Covariant-Based Structural Equation Modelling (CB-SEM) approach within Amos (v.23) was employed to test the proposed hypotheses. The findings revealed that GHRMS significantly enhances supply chain environmental sustainability by fostering eco-conscious HR practices. Green dynamic capability partially mediates this relationship, enabling firms to develop and adapt sustainable competencies. Additionally, institutional networking capability strengthens the indirect effect of GHRMS on supply chain sustainability, demonstrating the crucial role of external networks in achieving environmental goals. These findings underscore the importance of both internal organisational capabilities and external collaborations in driving sustainable supply chain practices in emerging economies. This study provides strategic insights for firms aiming to integrate GHRMS into their environmental sustainability initiatives, fostering a greener and more resilient supply chain ecosystem. © 2025 Elsevier Ltd
