The main purpose of this study is to investigate the effect of environmental transformational leadership on organizational citizenship behavior through the mediating role of perceived meaningful work in Tehran District 22 Municipality. The study population in this study is the employees of the municipal district of District 22 of Tehran. The number is about 400 people, and the sample size was obtained according to Cochran’s 196 formula. The research method in the present study is applied in terms of purpose and descriptive in terms of implementation method. The Kolmogorov-Smirnov test was used to test the normality of the data, which proved with 95% confidence that the variables had an abnormal distribution. Therefore, due to the abnormality of the data distribution, Pls software was used to analyze the data. The results showed that environmental transformational leadership has an effect on organizational citizenship behaviors.

This paper provides a comprehensive review of SURF (speeded up robust features) feature descriptor, commonly used technique for image feature extraction. The SURF algorithm has obtained significant popularity because to its robustness, efficiency, and invariance to various image transformations. In this paper, an in-depth analysis of the underlying principles of SURF, its key components, and its use in computer vision tasks such as object recognition, image matching, and 3D reconstruction are proposed. Furthermore, we discuss recent advancements and variations of the SURF algorithm and compare it with other popular feature descriptors. Through this review, the aim is to provide a clear understanding of the SURF feature descriptor and its significance in the area of computer vision.

The purpose of this study is to investigate whether the strategic orientations of organizations have an impact on the resilience levels of employees in the digitalized world. The sample for this research is based on the convenience sampling method. In this study, the sub-factors of strategic orientation, namely innovation, technological orientation, customer focus, and competitor focus, are examined, and their potential effects on resilience are analyzed. Our research emphasizes the importance of psychological resilience in organizations that undergo continuous changes due to the impact of digital transformation, as it enhances employee performance and has positive implications for firms. The field study associated with this research was conducted on 316 individuals working in the service sector in the context of Turkey. The data collected for the research were analyzed using SPSS 25 software. The research findings indicate that the components of strategic orientation have an impact on the levels of psychological resilience.

Forest transition is a trend change process from decreasing to increasing forest area in a country or region. Since the 1990s, ecological and environmental problems such as climate change and loss of biodiversity have received constant attention. The research theory and method of forest transformation has gradually become the frontier and hot topic pursued by international academic circle. With forest transformation as the theme, on the basis of introducing the origin of forest transformation research, along the development vein and internal logic of forest transformation research, this paper reviews the research progress of forest transition theory from the perspectives of Kuznets curve of forest environment and forest transition path, and summarizes the major issues in forest transformation research. The main direction of future research is proposed, including the impact of economic globalization on forest transition, the refinement of research units and the analysis of forest quality transition.

Cucumis sativus is an important vegetable crop in the world. Agrobacterium mediated transgenic technology is an important means to study plant gene function and variety improvement. In order to further accelerate the transgenic research and breeding process of cucumber, aiming at the Agrobacterium mediated genetic transformation method of cucumber, this paper expounds the research progress and existing problems of Agrobacterium mediated transgenic cucumber from the aspects of influencing factors of cucumber regeneration ability, genetic transformation conditions and various added substances in the process, and prospects the future of improving the efficiency of cucumber genetic transformation and the application of safety screening markers, in order to provide reference for cucumber stress resistance breeding and fruit quality improvement.
