Students’ e-learning use intention post-COVID-19
Authors: Mahapatra Sabita , Pandey Shivendra Kumar 
Published: February 2025

PurposeThe COVID-19 pandemic compelled educational institutions to shift from classroom interactions to electronic learning (e-learning). This study uses eTAM with usability dimensions to examine the use of e-learning for core academic activities during the COVID-19 pandemic. Leveraging the switching value framework, it investigates students’ preference for extending the use of e-learning to extracurricular activities post-pandemic. The study also integrates eTAM and the switching value framework to conceptualize students’ e-learning usage behavior in a synchronous learning environment.Design/methodology/approachStructural equation modeling was used to test the proposed research framework using a cross-sectional design. Data were collected through a survey conducted at two premier management institutes with broad national representation in India.FindingsThe result revealed that emotional cost had a more significant impact on perceived switching value compared to learning, sunk and reduced performance costs. Also, perceived switching value had a stronger influence on e-learning than the eTAM factors. Interestingly, learning support negatively influenced perceived ease of use and usefulness.Originality/valueThe study provides evidence that while eTAM largely explains e-learning usage during the pandemic, perceived switching value significantly influences its extended use post-pandemic. Our study challenges the belief that eTAM factors influence the continuous use of e-learning post-pandemic. The study insights can guide educational institutions, educators and policymakers in expanding the application of e-learning beyond the pandemic.

Authors: Du Yishan , Xu Liguo , Luo Wenchun , Xue Xian 
Published: February 2025

PurposeImproving the management efficiency of new principals in low-performing schools has important practical value and theoretical significance. Based on organizational socialization theory, this study adopts a single case study method to analyze in-depth the organizational socialization process of a new principal after taking over a low-performing school.Design/methodology/approachThrough three years of longitudinal data analysis in a Chinese school, the study establishes four stages that the new principal experienced after taking office. Then, it analyzes the interaction between the new principal and school members (vice-principals, department heads and teachers) in each stage.FindingsThree main determinants can be perceived to affect the effectiveness of the new principal: the former principal’s imprint, school members’ internal contagion and school members’ demand contradiction. The study further shows that the new principal needed to pay attention to school members’ attitudes toward himself and the former principal as well as focus on building relationships with management.Originality/valueThis study expanded the analysis from teachers to school members (including vice-principals and department heads) to comprehensively analyze the organizational socialization of a new principal.
Research on leadership potential: where are we and where should we be heading?
Authors: Raj Geethika , T. N. Krishnan 
Published: February 2025

Purpose
The purpose of this study is to clarify the definitional inconsistencies around the concept of “leadership potential” and differentiate it from related constructs, provide a comprehensive review of the literature and propose a research agenda to guide future studies.

Design/methodology/approach
The authors adopt a systematic literature review method to achieve this purpose. Adhering to the established guidelines, they analyzed 81 empirical articles published in 27 leading journals from 2011 to 2024.

Findings
Despite its prominence in discussions of leadership emergence, development, effectiveness and promotability, the literature lacks consensus on operationalizing leadership potential. In response, the authors propose a novel operationalization based on Pinder’s (1988) three dimensions of motivation, namely – direction, intensity and persistence of behavior. The analysis of this paper structured through the theory-context-characteristics-method (TCCM) framework identifies several critical gaps: One-third of the reviewed studies lack a theoretical foundation, while the remaining predominantly rely on trait and cognition-based approaches; most research emphasizes individual-level predictors and outcomes, with limited exploration of contextual factors; and quantitative approaches dominate the field leaving room for alternative methodological approaches. Based on these observations, a future research agenda using TCCM has been proposed.

Originality/value
This study contributes uniquely to the leadership literature by clarifying the distinctions between “leadership potential” and related constructs, introducing an operationalization grounded in Pinder’s motivational framework and presenting a holistic view of the literature on leadership potential. Further, this study advances the field by proposing a future research agenda, an aspect previously unexplored. Additionally, the authors use the TCCM framework, a guided framework for systematic literature review that has not been adopted in the leadership literature.

Phage‐derived proteins: Advancing food safety through biocontrol and detection of foodborne pathogens
Authors: Choi Dahee , Ryu Sangryeol , Kong Minsuk 
Published: February 2025

AbstractThe emergence of antimicrobial‐resistant foodborne pathogens poses a continuous health risk and economic burden as they can easily spread through contaminated food. Therefore, the demand for new antimicrobial agents to address this problem is steadily increasing. Similarly, the development of rapid, sensitive, and accurate pathogen detection tools is a prerequisite for ensuring food safety. Phage‐derived proteins have become innovative tools for combating these pathogens because of their potent antimicrobial activity and host specificity. Phage proteins are relatively free from regulation compared to phages per se, and there are no concerns about the transduction of harmful genes. With recent progress in next‐generation sequencing technology, the analysis of phage genomes has become more accessible, and numerous phage proteins with potential for biocontrol and detection have been identified. This review provides a comprehensive overview of phage protein research on food safety from 2006 to the present, a pivotal period marked by the certification of phages as Generally Recognized As Safe (GRAS). Emphasizing recent advancements, we investigated the diverse applications of various phage proteins for biocontrol and detection purposes. While highlighting the successful implementation of these proteins, we also address the current bottlenecks and propose strategies to overcome these challenges. By summarizing the current state of research on phage‐derived proteins, this review contributes to a deeper understanding of their potential as effective antimicrobial agents and tools for detecting foodborne pathogens.
Study of Aedes albopictus Hatching Rate by Low‐Temperature Stress
Authors: Won Min Hyeok , Choi Kwang Shik 
Published: February 2025

ABSTRACTAedes albopictus overwinters as eggs and lays diapause eggs under conditions of low temperatures, low humidity, and short photoperiods. We compared the hatchability of diapause and nondiapause eggs in response to cold stress. Nondiapause eggs were acquired at 27°C ± 1°C, 70% ± 5% humidity, and 16:8 (L:D) photoperiod, and diapause eggs were acquired at 21°C ± 1°C, 40% ± 5% humidity, and 8:16 (L:D) photoperiod. The obtained eggs were dried under the same conditions and then exposed to low‐temperature stress for each temperature and time. After that, eggs were transferred to a thermostat to induce hatching at room temperature, and the hatching rate and the time required for hatching were measured and analyzed by two‐way ANOVA and multiple regression analyses. When exposed to low temperatures for 1–24 h at a temperature of 0°C to −10°C, the diapause eggs had a hatching rate higher than that of nondiapause eggs in all sections. The difference in hatching rate according to temperature, exposure time, and diapause status was all considered significant at −6°C or less (two‐way ANOVA). A significant regression equation was calculated to estimate the hatching rate, a dependent variable (R2 = 0.439, p < 0.000). We found a significant difference in hatching rates for low‐temperature stress between diapause eggs and nondiapause eggs of Ae. albopictus, which may explain why Ae. albopictus spreads in high‐latitude regions. The morphological differences between diapause and nondiapause and variables such as dryness and light intensity should be studied to understand the overwintering of Ae. albopictus.
The impact of fruit size on internal browning in pineapples
Authors: Zhang Mengzhuo , Zhu Changsong , Na Qiting , Cao Hui , Tian Cong , Liu Guangsen , Meng Lanhuan 
Published: February 2025

AbstractA typical symptom of post‐harvest pineapple (Ananas comosus L.) internal browning is influenced by multiple factors. However, the precise mechanism through which fruit size influences the occurrence of browning remains unclear. Therefore, this study aimed to investigate the impacts of fruit size in browning and its possible mechanisms in harvested pineapple fruit using physical and biochemical analysis and RNA‐seq. Disease incidence was assessed in four groups of fruits (1, 1.5, 2, and 2.5 ± 0.2 kg), with the two most significant groups (1 and 2.5 ± 0.2 kg) selected for detailed analysis. The results showed that the large pineapple fruits had faster browning senescence and membrane lipid peroxidation, higher respiration intensity, more reactive oxygen species accumulation, and higher malondialdehyde content. Likewise, lower antioxidant capacity such as ascorbic acid, ascorbate peroxidase, catalase, and superoxide dismutase and higher polyphenol oxidase activity, peroxidase activity, phenylalanine ammonia‐lyase activity, and lipoxygenase activity. It can be concluded that the large pineapple fruits were severely subjected to oxygen stress and membrane lipid peroxidation during storage. Gene ontology enrichment reveals that this relates mainly to oxidoreductase and glutathione metabolism. The large pineapple fruits accelerated AsA–GSH cycle pathway metabolism. Real‐time quantitative PCR shows downregulated expression of AcAPX1, AcAPX6, AcAPX6 × 1, AcCAT2, AcSOD[Fe]2, and AcSODX2 in large pineapple fruits, whereas AcPPO and AcLOX upregulated expression. This study offers insights into fruit size and browning. Future molecular techniques may reduce fruit browning.

Authors: Tong Kai , Fu Jimei , Dai Liangli , Liao Yuxue , Zhang Liang , Ao Zonghua , Deng Mengsheng , Wang Wenting , Li Zhaoling 
Published: February 2025

AbstractGualou (Trichosanthes kirilowii Maxim) and Xiebai (Allium macrostemon Bunge) have been extensively studied for their diverse active ingredients, which include flavonoids, polysaccharides, and triterpenoids. This study employed a single‐factor experiment alongside the Plackett–Burman design and utilized response surface methodology to optimize the ultrasonic‐enzyme‐assisted extraction (U‐EAT) method for the functional components in Gualou and Xiebai (GLXB). The optimal extraction conditions were identified as a solid‐to‐liquid ratio of 1:11 g/mL, an alcohol concentration of 55%, an enzyme concentration of 1.2%, and an extraction temperature of 40°C. The yields of flavonoids, polysaccharides, and triterpenoids obtained were 0.94 ± 0.05, 260.46 ± 1.78, and 118.69 ± 0.71 mg/g, respectively, demonstrating increases of 59.19%, 29.03%, and 46.10% compared to HL (HL, the traditional reflux extraction method). Furthermore, in vitro digestion of the GLXB extract demonstrated significant lipid‐lowering and hypoglycemic effects. The GLXB extract facilitated the flocculation of lipid droplets during lipid digestion and exhibited the capacity to reduce the rate of fat digestion. These findings indicate that the U‐EAT significantly enhanced the content of active ingredients in GLXB and improved the hypoglycemic and lipid‐lowering activities of the GLXB extract, highlighting its potential for further development and application in functional foods.
Genetically Predicted Plasma Metabolome Mediates the Causal Link Between Immune Cells and Risk of Gout
Authors: Wei Yi , Yu Jiangyi 
Published: February 2025

ABSTRACTBackgroundGout is a prevalent metabolic disorder characterized by a multifaceted process of development. Recent research has emphasized a robust correlation between the immune response and gout. Nevertheless, it is still uncertain if this connection is causative. Hence, the objective of this study was to investigate the causal relationship between immune cells and gout, while also analyzing the role of the plasma metabolome as metabolic mediators in this biological process.MethodsThis study explored the causal link between different subtypes of immune cells and gout using two‐sample Mendelian randomization (MR). To confirm the reliability of the findings, reverse MR analysis, steiger test and sensitivity tests were conducted. A two‐step mediation analysis was used to gain insight into the role of plasma metabolites as intermediate mediators.ResultsThis two‐sample, bidirectional, two‐step MR analysis found a nominal causal link between 33 immune cells as well as 47 known plasma metabolites and gout. Reverse MR analysis and sensitivity tests demonstrated the reliability of the MR results. In addition, we found that Tetradecadienedioate (C14:2‐DC) played a partially mediating role in the CD4 on activated CD4 regulatory T cell and gout pathways, with a mediating proportion of 13.16%, (95% CI = 0.65%–25.67%, p = 0.034).ConclusionThe objective of our research was to investigate the possible causative connection between immune cells and gout. Our findings indicate that certain plasma metabolites may play a role in mediating this association. This study offers novel insights and sources of information that may contribute to the early detection and proactive measures to avoid gout in the future.
