润色如下内容：This letter serves as a graduate study recommendation letter for Miss Dingning Yang, one of my exceptional undergraduate students. As her instructor of the Organisational Behaviour course, as well as the project leader who supervised her, I have known Dingning for years and highly recommend her to apply for the designated programme at your university and firmly believe that her academic background has equipped her with essential skills and theories to support her further research on behavioural science. 
She was one of the most active students in the class of Organisational Behaviour and always vigorously answered questions and led groups to complete discussions and assessments. She has also demonstrated excellent commitment and is highly persuasive during the group decision-making process, making other team members focus on main objectives of group work and assessment and cooperate with each other. The group which was led by Dingning was ranked the first in the final group assessment in the class. Besides, she participated in several research projects related to Organisational Behaviour and acted as an efficient and professional researcher who extremely accelerated the progress of these projects. She conducted five focus groups as part of my involvement in behavioural lab research focusing on conflict management and social influences and cultivated her qualitative research skills and communication skills by providing professional guidance to research participants and designing feasible schemes of focus groups. She also played a significant role in crafting survey scenarios for social networks, generating stimuli related to social class and status cues, and collecting data that illuminates the impact of AI on organizational behaviours, which shows her skills in creative writing, experiment design, and literature review. Finally, she suggested a comprehensive plan for recruiting survey participants and executing a longitudinal study aimed at predicting how group dynamics, particularly within dormitories, influence academic performance and career planning. In another study on consumers’ behaviour and pink tax, she combined consumer and organisational behaviour theories and highlighted extensive humanistic care for gender equality regarding the pink tax and female-based industries. She presented extraordinary research skills, such as knowing how to establish sophisticated experiment design and collect high-quality datasets. Taking advantage of several programming languages, she is able to perform essential data analysis to offer quantitative research outcomes. 
As far as I know, Dingning excels in English and is highly motivated to acquire proficiency in this language using various resources, such as TV series, podcasts, newspapers, and magazines in English. She organised the “First-Year English Student-Helper Programme” to collect numerous materials such as speech transcripts of the US presidents and TED talk shows to provide training sessions to improve oral English and English writing for first-year students. It is very impressive to have witnessed that she voluntarily assisted other students to support their individual development by improving their English speaking and writing skills, and her public spirit and enthusiasm are remarkable.
To summarise, this applicant has advanced potential for research, keen perceptions of research ideas, amazing communication skills and leadership, higher-than-average writing skills, and most importantly, her ambitions in further research on behavioural science. Thus, I hope that she can be admitted to your university and contribute to relevant research fields by obtaining world-leading theories and networks from your academic community.
