In service-oriented organizations such as banks, learning, knowledge management, and digital innovation enhance the efficient utilization of the organization's available time, resources, and capabilities. The need to generate new knowledge using information technology is one of the challenges that managers face today. In the new paradigm, characterized by a competitive and knowledge-oriented environment, organizations should view innovation as an essential strategy to maintain competitiveness. Through digital innovation, new opportunities to access markets and gain competitive advantages at the national and international levels will be created. One of the challenges that organizations face today is the need to develop new knowledge based on information technology due to changes in the environment. Therefore, this research aims to determine the impact of knowledge management through organizational learning on digital innovation in Refah Bank.

This research is quantitative. A cross-sectional and hierarchical fuzzy logic approach was conducted with a sample size of 2022. The research population consisted of 9063 managers and employees from Refah Bank across the country. A simple random sampling method was used, with a sample size of 368 people. An electronic questionnaire, which incorporates the Lawson Knowledge Management Questionnaire, the short form of the Sange Organizational Learning Questionnaire, and the Kane and Ho Digital Innovation Questionnaire, draws on digital knowledge from research literature. Its validity and reliability have been confirmed, and it is utilized for data collection. Data analysis is conducted using Smart PLS 2 software, and the research's conceptual model is tested using the partial least squares technique. Partial Least Squares (PLS) method is utilized to validate and fit the research model.

The study confirms the mediating effect of organizational learning on the relationship between the dimensions of knowledge management and digital innovation. Knowledge management variables have an impact on organizational learning. Organizational learning has a significant impact on digital innovation.

According to the research findings, the acquisition, creation, sharing, and maintenance of knowledge, as well as digital knowledge, have an impact on digital innovation through organizational learning. The research results indicate that organizational learning plays a crucial role in connecting knowledge management and digital innovation. In previous research, little attention has been given to organizational learning in the context of knowledge management's impact on digital innovation. Therefore, the current research aims to address this gap. The qualitative research conducted by Di Vaio et al. in 2021 on the content of articles related to knowledge management and digital innovation indicates that there has been no research on the impact of knowledge management and digital innovation. Furthermore, there has been no governance framework to measure the impact of digital transformation and knowledge management on each other. Knowledge management, like a system, is considered an important input, with organizational learning as a key process, and digital innovation as a vital output for today's organizations. Banks can enhance their organization's digital innovations by implementing knowledge management and organizational learning systems. It is essential for the management to understand the concept of knowledge management and to support the knowledge management program through resource allocation and revising the priorities of Refah Bank. Digital innovation tools should align with the expected processes of knowledge management and organizational learning. Careful planning is essential in this case. It is suggested to establish a knowledge creation working group to reduce the influence of individual biases. It is important to prioritize the role of human resources in advancing knowledge management and to make decisions that facilitate the production, storage, and dissemination of knowledge within the organization. Banks can share knowledge by updating electronic archives of documents and through the organizational portal, software groups, proposal management systems, and thus improve employee efficiency and document knowledge. This also allows for the utilization of valuable hidden employee knowledge in future work. As a result, they achieve organizational innovation, which is considered a crucial outcome for organizations today. Other mediating variables, such as industry type, management style, organizational culture, and other factors influencing digital innovation, should be considered in future research.

Marketing channels are the systems consisting of interdependent operators. Interdependence should be managed, and power is the way to manage it. Attention to brand social power to gain power, its proper usage and power maintanance, is one of the most important issues in marketing channels. The purpose of this article is to elaborate the power factors deriving from the French and Raven's typology and the importance of each base in the marketing channel of the teachers and master students of marketing management at Alzahra University. The innovation of this research in explaining the factors of power in this channel is reached through using the social network analysis approach. Using this approach in explaining power factors as well as brand social power, has not been considered in other researches so far.In this study, the characteristics of the communication network and social brand position of faculty members and students of the marketing management group in Alzahra University organizational network are investigated. The social network analysis method was used for data gathering and data analysis is done by NodeXl. This study examines brand social power as one of the social power approaches in the marketing channel of Alzahra University professors and students. Findings show that the power of channel members does not necessarily depend on the organizational hierarchy, but rather on the social brand of each of them and their position in the minds of the individuals. In other words, people with high social brand power may be inferior or inferior to other powers. Specifically, the most influential people on the network are not necessarily persons with higher position, and even these people may tend not to have relationship with others or may have less influence in their relationships.

Seed priming is a method in which the water absorption in a controlled manner is allowed to seed before plantinguntil the first germination activities begin, but without allowing radicle emergence.In order to investigate the possibility for increasing wheat tolerance to water tension by seed priming technique, the present experiments was performed as factorial and as a randomized complete blocks design with three replications in Greenhouse Agriculture Faculty of Shiraz University. The experimental treatments included two cultivars of wheat (Azar2 and Shiraz), four levels of priming (non-priming, osmo-priming and phosphopriming and hydropriming) and four levels of water tension (intervals of irrigation 2 (non-tension), 4, 6 and 8 days). For both the two wheat cultivars, the highest tension level (8 days irrigation intervals) caused increasing in catalase amount activity at the probable level of 5 percentage. Increasing in water tension leads to increasing in the amount of catalase at the probable level of 5 percentage. By increasing the water tension, the amount of ascorbic peroxidase and peroxidase enzymes increased significantly. Types of different priming treatments did not result in significant difference at the probable level of 5 percentage in catalase enzyme activity. In this research, Azar2 cultivar compared to Shiraz cultivar was known as the more resistant to water tension. Peroxidase and ascorbic peroxidase enzymes activity is influenced by osmopriming treatment increased by 01/10 and 21.4 percentage respectively, compared to the no-priming. The maximum proline content (13l/68 micromole per gram fresh weight(was related to osmopriming treatment in Azar2 cultivar under the highest tension levels (8 days irrigation intervals). According to the results of this research, it appears that osmopriming treatment by effect on antioxidant defense system of plant, would be involved in the process of increasing drought resistance in wheat seedlings.

Abstract In order to determine the actual evapotranspiration of tomato in the greenhouse, crop and soil-water stress coefficients were surveyed. To compare the actual evapotranspiration at different irrigation intervals (1, 2, 4, 6 and 8-day), a completely randomized blocks design with four replications was performed. The present study was carried out in a greenhouse covered by 4 mm thick glass. Maximum and minimum temperatures and solar radiation were measured inside the greenhouse once in 24 h. Relative humidity was measured in the greenhouse once in 2 h. Microclimate data were measured in a metrological station, 100 m from the greenhouse, simultaneously, at outside the greenhouse. Reference crop evapotranspiration was calculated by FAO Penman-Monteith method for inside and outside of the greenhouse. Results indicated that the reference evapotranspiration in the inside of the greenhouse was 73% of outside the greenhouse. The actual evapotranspiration of tomato for inside of the greenhouse was determined by using the water balance method. By using the pergeometer and albidometer data, the crop coefficient for inside the greenhouse at three different stages (development, mid, and end) of growth was determined as 0.85, 1.0 and 0.77, respectively. Soil-water stress coefficient, with readily available coefficient of 0.7, was determined to be in the range of 0.53 to 0.98 for all the treatments. This coefficient was 0.88 for water-stressed 4-day treatment, and reduced to 0.72 for 8-day treatment.
