How does the lecturer cadre contribute to higher education institutions?

Hello….In the context of higher education institutions, could you elaborate on the multifaceted contributions that members of the lecturer cadre make to the academic environment? I am particularly interested in gaining a nuanced understanding of how individuals in the lecturer cadre play a vital role in the educational landscape. Specifically, how do their responsibilities extend beyond conventional teaching roles, and in what ways do they contribute to the broader academic community?
