Half sphere exposure Half sphere exposure Half Sphere Exposure (HSE) is a protein solvent exposure measure that was first introduced by . Like all solvent exposure measures it measures how buried amino acid residues are in a protein. It is found by counting the number of amino acid neighbors within two half spheres of chosen radius around the amino acid. The calculation of HSE is found by dividing a contact number (CN) sphere in two halves by the plane perpendicular to the Cβ-Cα vector. This simple division of the CN sphere results in two strikingly different measures, HSE-up and HSE-down. HSE-up is defined
Public sphere pedagogy sphere pedagogy might alienate students and community members unaccustomed to this type of dialectic experience. In addition to its exclusionary nature, attention has also been called to Habermas' privileging of a hegemonic public sphere. Michael Warner argues that the bourgeois public sphere was structured to be affable to those privileged few who made up the powerful upperclass. While students participating in public sphere pedagogy application receive special training in their classrooms, the same is not necessarily true of community members who participate. This specialized student training draws two critiques. First, conceiving of public pedagogy as a form of instruction risks
