Women entrepreneurs use virtual social networks in their professional relationships. These relationships with higher quality leads to better performance in their businesses. The present study aimed to analyze the effects of virtual social networks on improving rural women’s entrepreneurship. The statistical population of the study included all members of the Agricultural Development Specialized Holding Companies in Fars province in Iran. The study was conducted using survey and stratified random sampling methods with 269 individuals participated via questionnaires. The results indicated that virtual social networks had a favorable effect on rural women’s businesses. There was a significant difference between women in the different studied counties regarding the effects of virtual social networks on business. In addition, a significant difference was observed between women in various groups regarding the effect of virtual social networks on business. In addition, greater effect of virtual social networks on women’s businesses led to higher business resilience among the women entrepreneur and their businesses, which resulted in increasing the women’s information about business activities and their entrepreneurial activities in their businesses. Further, more use of social networks by the women led to more use of marketing methods and strategies. Therefore, it is suggested that Agricultural Development Specialized Holding Companies use the functions of virtual social networks in order to information transfer, networking and online training for members when necessary. Also provide the necessary training in the application of appropriate marketing methods and strategies to rural women entrepreneurs using these networks.

Every year, approximately one-third of the total food produced for human consumption is lost or wasted due to various reasons. This level of wastage has substantial adverse impacts on the environment, economy, and society. Numerous studies have proposed various policies to address the issue of food waste, such as incorporating technology into existing supply chains. However, concerns about their effectiveness and unintended consequences have led researchers to emphasize market-based approaches for waste reduction. The present study was carried out to estimate waste and investigate the potential for developing different marketing channels as market-based approaches to reduce waste in the leafy vegetable supply chain in Kermanshah province. To achieve this purpose, a system dynamics modelling of the waste system in the leafy vegetable supply chain was developed by using the literature review and interviews with experts and stakeholders. The tool for collecting research data was a questionnaire. The statistical population of this study is two groups including 22 experts and 728 actors in the leafy vegetable supply chain. Based on the findings, around 31,000 tonnes (39%) of leafy vegetables are wasted annually across the supply chain. The research scenarios indicate that the establishment of processing industries will effectively decrease the overall waste of leafy vegetables from around 31,000 tons to approximately 20,000 tons annually. Therefore, government initiatives and policies in the field of leafy vegetable exchange in the study area must focus on supporting businesses associated with leafy vegetable processing industries and establishing infrastructure prerequisites for these industries.

Knowledge, as one of the pillars of success, is an essential factor for innovation, production and economic growth. Knowledge management is a new strategy that organizations, would need that so as to increase their performance and success. In case companies don’t use knowledge management system correctly and at proper time, they would be either faced with failure or obliged to leave the arena of contest. Agricultural knowledge-based companies have a key role for the regeneration of the agriculture and increase of the employment of agricultural graduates in this field. As presently the challenge of managers is to provide a suitable environment for the growth of the human mind in knowledge-oriented companies that embrace a cutting-edge approach to knowledge management, wherein knowledge is tailored to fit the specific context, are poised for success. By fostering effective learning, this approach leads to enhanced performance and improved efficiency. In this study, many studies were reviewed and generations of knowledge management were analyzed with a paradigmatic approach. Almost 100 related books and articles were reviewed through archival research. The findings showed that knowledge-based companies should go from the first generation of knowledge management to the use of the fourth generation; that way the internet use, social networks, analytical tools, intelligent agents, etc., might have a great participation with one another, which leads to their stay in the contest scene, and their faster achievement of future-oriented and dynamic results. Therefore, it is suggested that agricultural knowledge-based companies have focus on transformational management and its characteristics.

Purpose: The purpose of this article is to depict inequality cases and examine the complexity of black teachers' experiences in the British white system. For this reason, the researchers of this article applied concepts of whiteness, intersectionality, and battle fatigue to Boakye's I Heard What You Said (2022). Methodology: This is qualitative research and its nature is deductive. The theoretical framework primarily was based on Crenshaw and Bradbury's definitions of intersectionality, Kincheloe’s of whiteness, and Smith’s of battle fatigue. Loden and Rosener's diversity wheel was also used to clarify various cases of intersectionality. I Heard What You Said (2022) contains 56 experiences of a black teacher in the British white education system. The sample size includes all 56 experiences of the black teacher. Findings: Finding shows that Whiteness and the internalization of white characteristics play a significant role in defining black identities. They are inferior not only because of their different skin color but also because of numerous criteria and the differences from whites. In this educational system, all learning is also consistent with white beliefs and the norms that define them within the system. Boakye mentions that “‘white is light’ imagery and ‘white is right’ ideology” is imposed on students from the early days of attending schools which demonstrates white supremacy in the British education system. In the British educational system, not only are teachers marginalized, but also they have to make an effort in order to institutionalize white beliefs and ideas in students’ minds. The British education system ignores diversity in its curriculum, wanting to follow the concept of “sameness” in education. The narrator criticized the aim of the National Curriculum of England in the late 1860s, based on the view of Mattew Arnowl, citing some ambiguous concepts such as “essential knowledge”, “educated citizens”, “the best that has been thought and said”, and “…engender an appreciation of human creativity and achievements …” He explained the condition in Arnold's time in 1860. It highlighted that the white education system shows no changes in its aim through time. It seeks to stabilize its characteristics in the educational system in relation to ignorance of differences and white supremacy in all parts of the educational system in British. Furthermore, applying the concept of intersectionality, it becomes clear that each proof emphasizes the connection of the particular sections, which to some extent differs from others. Considering the concept of intersectionality in the context of whites being superior, makes the causes more complex. Applying the concept of battle fatigue shows that the black teachers fight against racism even if they believe they could bring insignificant changes to the British educational system. Conclusion: The research shows that black teachers' experiences of discrimination in the British education system are based not only on their skin color as black but on the connection between different dimensions of diversity and criteria in different areas of the personal, sociocultural, and organizational sphere. There is a need to revise the National Curriculum of Britain to start work on eliminating inequalities in the education document and to extend it to the whole education system.
