Purpose: To investigate the factors affecting innovation in Six Sigma improvement teams. Based on Activation Theory, this study explores the possibility of an inverted U-shaped association between psychological safety and innovation and examines how intrinsic motivation moderates this relationship. Design/methodology/approach: Moderated regression analysis is carried out to test the curvilinear relationship, using data collected from 324 members of 102 Six Sigma improvement teams from two European manufacturing firms. Findings: The findings demonstrate that the beneficial effect of psychological safety reaches an inflection point, after which its relations with innovation cease to be linear and positive; this gives the relationship a curvilinear pattern (inverted U-shaped). Further, intrinsic motivation has a supportive effect in enhancing the beneficial impact of psychological safety on innovation, and in shifting the inflection points to a higher level; this demonstrates their synergetic influence on innovation. Originality/value: The impact of psychological safety on innovation is examined from the new perspective of a curvilinear relationship. This is one of the first studies to investigate the combined effects of individual (intrinsic motivation) and team-level antecedents (psychological safety) on innovation in Six Sigma teams. The study provides insights into how Six Sigma enhances innovation and offers some valid inputs to the current academic debate on this topic. [ABSTRACT FROM AUTHOR]

Precision nutrient management is a modern approach for optimizing nutrient supply in fruit crops, ensuring that plants receive the actual amount of essential elements at the right time and place. Traditional nutrient management methods often undergo deficiencies, leading to over-fertilization, uneven distribution of nutrients, environmental pollution, and economic inefficiency. These review paper challenges can be addressed by providing real-time data of soil conditions, plant health and nutrient levels. This strategy depends on advanced technologies such as remote sensing, variable rate technology, fertigation, slow/control release fertilizer, and organic amendments to weave nutrient application to the specific needs of each crop and individual plant within a field. It is emphasized by its potential for plant growth and development, increased crop yield, optimized resource utilization and mitigated environmental concerns. By fine-tuning nutrient application, farmers can achieve better economic returns while promoting sustainable agriculture. Precision nutrient management for fruit crops is characterized by a scarcity of studies exploring the application of advanced technologies and data-driven approaches. There is a need for more in-depth investigation to develop and validate precision nutrient management strategies tailored to the unique requirements of different crops. Closing this research gap will contribute to sustainable and optimized fruit crop production. In conclusion, precision nutrient management represents a paradigm shift in agricultural practices, offering a more sustainable and efficient approach to nutrient application in fruit crops. By untried advanced technologies and data-driven insights, farmers can optimize their resource use, enhance crop performance, and contribute to the long-term sustainability of agriculture.

Batteries play a crucial role in our daily lives, with separators being a key component influencing their functionality. The separators based on petrochemical for example polythene and polypropylene have been long favored for their chemical and thermal stability, their drawbacks in terms of sustainability, eco‐efficiency, and associated environmental risks are undeniable. In pursuit of sustainable development, there is a growing demand for biopolymer composite separators that offer a compelling combination of low cost, high mechanical and thermal stability, biodegradability, and renewability. Among these alternatives, cellulose‐derived separators have garnered significant attention from the scientific community. This review delivers a brief overview of cellulose's chemical structure, their types, delving into the intricate interplay of various electrodes and electrolytic solutions. The focus is then directed towards exploring diverse preparatory methods for cellulose‐derived separators, along with highlighting the promising factors associated with their adoption. Special attention is given to cellulose composite separators and the challenges they present. Highlights: Cellulose‐based composite separators in LIB/SIB batteries are discussed.Preparatory methods for eco‐friendly cellulose‐derived composite battery separators.Prominent affecting factors of separator performance have been elaborated.Special attention to the challenges cellulose composite separators present.
