Rooting for the story: Institutional sports journalism in the digital age

This dissertation examines contemporary daily sports journalism through the lenses of media sociology and new institutional theory. In-depth interviews with 25 sports journalists (reporters and editors) identified the institutionalized norms, values, practices and routines of American sports journalism, demonstrated how that institutionalization affects story selection, and showed how the profession is changing due to digital and social media. The interviews show that although traditional sports journalism is highly institutionalized, digital sports journalism is far less so. Traditional sports journalism is still centered around a story, and digital sports journalism follows Robinson\u27s (2011) journalism-as-process model. The journalists interviewed are expected to perform acts of both traditional and digital journalism during the same work day, which leads to tension in how they do their jobs

Using RIXS to uncover elementary charge and spin excitations in correlated materials

Despite significant progress in resonant inelastic x-ray scattering (RIXS) experiments on cuprates at the Cu L-edge, a theoretical understanding of the cross-section remains incomplete in terms of elementary excitations and the connection to both charge and spin structure factors. Here we use state-of-the-art, unbiased numerical calculations to study the low energy excitations probed by RIXS in undoped and doped Hubbard model relevant to the cuprates. The results highlight the importance of scattering geometry, in particular both the incident and scattered x-ray photon polarization, and demonstrate that on a qualitative level the RIXS spectral shape in the cross-polarized channel approximates that of the spin dynamical structure factor. However, in the parallel-polarized channel the complexity of the RIXS process beyond a simple two-particle response complicates the analysis, and demonstrates that approximations and expansions which attempt to relate RIXS to less complex correlation functions can not reproduce the full diversity of RIXS spectral features
