What Have Corporations Got To Do With It? A Political Economy Approach To Organizations And Climate Change, Annika Rieger

Research Collection School of Social Sciences

Ecological issues are often seen as only one of the many “problems” societies face today, even though they go deep and affect everything – from physical disruption and displacement to perhaps more subtle long-term changes in temperature, flora, and fauna that alter the face of the planet and the norms of everyday life. As a result of this view, the study of the environment has been siloed into the realm of “environmental sciences” with a few “environmental fill-in-the-social-science-blank” subfields scattered about. This is not to say that only “environmental” problems are important, but that across all disciplines and subfields, greater …

On Fractional Dunkl-Type Laplacian, Saba Ibrahim Aldan

Theses

This thesis presents a comprehensive study of the fractional Dunkl-type Laplacian operator (−∥x∥ Δ��)^σ for 0<σ<1, through four equivalent key characterizations: the heat semigroup characterization, the pointwise characterization, the spherical mean characterization, and through an extension theorem. These characterizations offer different perspectives on the operator ∥x∥Δ_��, generalizing known results for the Euclidean Laplace operator by incorporating reflection symmetries, making it highly relevant in the harmonic analysis of root systems.

By exploring these characterizations, the thesis highlights the deep connections between the fractional operator (−∥x∥Δ_��)^σ and harmonic analysis, as well as its broader applicability in mathematical physics and partial differential equations.

The Fantasy Genre In Spanish Music Videos, Julia Sainz Cortés

Capítulos de libros

If we were to take the launch of MTV as the beginning of what we know as music video, we could affirm that the dialogue between this medium and the fantasy genre has been a constant to this day.

The first and most evident case of this synergy was found in 1983 with an experiment driven by CBS to demonstrate the commercial impact of music videos on record sales. In Billy Jean (Barron, 1983) and Thriller (Landis, 1983), fantasy narrative is presented from two different approaches.

Michael Jackson stars in both music videos. The first one provides a social critique …
