1. Research design: Correspondents are usually the leaders of research, and they are responsible for designing and planning the whole research project. This includes determining research objectives, choosing appropriate research methods and designing experimental schemes. These tasks require profound professional knowledge and rich research experience, which is one of the main contributions of communication authors.
2. Data collection and analysis: Correspondents are usually also the main personnel responsible for data collection and analysis. They need to ensure the quality and integrity of the data, and correctly interpret and analyze the data. This requires rigorous scientific attitude and efficient data processing ability.
3. Paper writing: The correspondent is responsible for writing most of the contents of the paper, including introduction, methods, results and discussion. They need to express the complicated research process and results in a clear, accurate and logical way, which requires high language expression ability and writing skills.
4. Paper revision and peer review: Correspondents need to revise the paper several times to ensure its quality. They also need to be responsible for communicating with the reviewers, handling their feedback, and finally deciding whether to accept or reject the reviewers' opinions.
5. Academic leadership and guidance: As a correspondent, he also needs to play a leading and guiding role in the research team, help team members solve problems encountered in the research process, provide professional advice and promote research progress.
So the correspondent can prove his contribution in the paper through the above aspects. At the same time, they also need to have enough evidence to support their claims, such as providing relevant e-mail records and meeting records.
