    Innovation is considered essential for today's organizations to survive and thrive. Researchers have also stressed the importance of leadership as a driver of followers' innovative work behavior (FIB). Yet, despite a large amount of research, three areas remain understudied: (a) The relative importance of different forms of leadership for FIB; (b) the mechanisms through which leadership impacts FIB; and (c) the degree to which relationships between leadership and FIB are generalizable across cultures. To address these lacunae, we propose an integrated model connecting four types of positive leadership behaviors, two types of identification (as mediating variables), and FIB. We tested our model in a global data set comprising responses of N = 7,225 participants from 23 countries, grouped into nine cultural clusters. Our results indicate that perceived LMX quality was the strongest relative predictor of FIB. Furthermore, the relationships between both perceived LMX quality and identity leadership with FIB were mediated by social identification. The indirect effect of LMX on FIB via social identification was stable across clusters, whereas the indirect effects of the other forms of leadership on FIB via social identification were stronger in countries high versus low on collectivism.

    Food Legumes and Rising Temperatures: Effects, Adaptive Functional Mechanisms Specific to Reproductive Growth Stage and Strategies to Improve Heat Tolerance

    Ambient temperatures are predicted to rise in the future owing to several reasons associated with global climate changes. These temperature increases can result in heat stress- a severe threat to crop production in most countries. Legumes are well-known for their impact on agricultural sustainability as well as their nutritional and health benefits. Heat stress imposes challenges for legume crops and has deleterious effects on the morphology, physiology, and reproductive growth of plants. High-temperature stress at the time of the reproductive stage is becoming a severe limitation for production of grain legumes as their cultivation expands to warmer environments and temperature variability increases due to climate change. The reproductive period is vital in the life cycle of all plants and is susceptible to high-temperature stress as various metabolic processes are adversely impacted during this phase, which reduces crop yield. Food legumes exposed to high-temperature stress during reproduction show flower abortion, pollen and ovule infertility, impaired fertilization, and reduced seed filling, leading to smaller seeds and poor yields. Through various breeding techniques, heat tolerance in major legumes can be enhanced to improve performance in the field. Omics approaches unravel different mechanisms underlying thermotolerance, which is imperative to understand the processes of molecular responses toward high-temperature stress

    The current study was designed to investigate the effect of eugenol on histopathological changes and oxidative stress caused by torsion/detorsion in the ovary of adult female rats. In this study, forty-eight female Wistar rats were classified into six groups; Sham and 2 healthy group receiving 30, 60 mg/kg eugenol; ovarian torsion/detorsion; and 2 experimental groups receiving 30, 60 mg/kg eugenol. After ten days, the plasma levels of oestrogen, testosterone, and some oxidative stress markers were assessed. also, the histomorphometric study was performed. A marked degenerative changes in the TD group was observed (p < .001). The oestrogen, GPX, and SOD levels were remarkably declined in the G2 group, while they were reversed to the baseline values in groups receiving eugenol. The concentration of malondialdehyde (MDA) was remarkably increased during the ischaemia (p < .001). The treatment with eugenol significantly diminished MDA levels in different groups (p < .001). Our finding indicated that eugenol could protect the ovarian tissue against oxidative stress and tissue injury induced by torsion/detorsion.IMPACT STATEMENT What is already known about this subject? Ovarian torsion is one of the commonest gynecological emergencies in all age groups of the female gender. Timely diagnosis and management of ovarian torsion are crucial, especially for women of reproductive age. Detorsion is one of the interventions used for the prevention of ovarian tissue damage. Ovarian ischaemia/reperfusion is a pathophysiological condition in which decreased blood flow, and oxygen deficiency (ischaemia) are observed in ovarian tissues as a result of ovarian torsion. Following torsion, the inflammatory response induced by detorsion (reperfusion) leads to vascular endothelial cell apoptosis and microcirculation abnormalities, which are responsible for the cause of ovarian tissue damage. What do the results of this study add? This study found that eugenol, an antioxidant and anti-inflammatory agent, could be used experimentally to diminish the I/R damage in the ovary through the attenuation of detrimental histological events, decreasing the serum level of MDA and testosterone, and increasing the level of SOD and GPX enzymes. To date, there is no report on the application of eugenol for diminishing T/D-induced oxidative stress in the ovary. What are the implications of these findings for clinical practice? Eugenol has been shown to possess therapeutic properties in patients with ovarian torsion. Further clinical studies are necessary to prove the beneficial effect of eugenol on the prevention of I/R-induced ovarian damage
