Silence and writing: the voices that inhabit us (Woolf, Duras, Perec, Celati)

My thesis investigates the forms, modalities and issues related to the notion of 'silence' in the texts and poetics of Virginia Woolf, Marguerite Duras, Georges Perec and Gianni Celati. This study relates to the 20th century European context and is set within the framework of music-literary studies, since silence is an acoustic phenomenon that concerns the whole word, thus also the written word. The material is structured according to a distribution that firstly involves the construction of a methodological framework that employs music-literary studies, the philosophy of language, the aesthetics of reception and psychoanalytic trauma studies; secondly, an analysis of some of the autobiographical works of the mentioned writers was undertaken, with a particular focus on the notion of trauma associated with silence; thirdly, the focus was placed on the theme of silence in the novelistic and fictional writings of the same authors; finally, a reflection on the poetics and aesthetics of silence was proposed. This study, which brings together several perspectives on silence, aims to shed light, through a comparative and transmedial approach, on the necessity of silence that is inherent in the word, and not a phenomenon opposed to it.

Incentives, Sustainability, and Law: The relationship between executive pay regulation and corporate social responsibility

What is the relationship between executive pay regulation and corporate social responsibility (CSR)? Currently, CSR is neither sufficiently included in economic research on executive pay, nor is pay regulation considered as a potential instrument in the growing body of CSR legislation. The successful proliferation of CSR in business practice and the attention policymakers and legislators now pay to it, however, have raised the importance of answering these questions. Thus, this blind spot in corporate governance—the relationship between compensation, CSR, and law—is the topic of this thesis. The dissertation approaches these issues in two subsequent research question: first, the role of executive pay regulation as an institutional determinant of CSR engagement is identified. From the results of this, the second research question arises: should legislators promote CSR engagement and—if so—how? Lastly, a case study is conducted to map how the influence of index funds as an important driver of CSR in corporate governance should be accommodated in the design of CSR legislation. The research project shows that pay regulation is part of the institutional determinants of CSR and, depending on its design, can incentivise or discourage different forms of CSR engagement. As a form of private self-regulation, CSR is closely interconnected with legal rules and the result of complex underlying drivers inside and outside the firm. The study develops a differentiation of CSR activities to accommodate this complexity, which is applied in an analysis of pay regulation. Together, these inquiries form a comprehensive picture of the ways in which pay regulation sets incentives for CSR engagement. Finally, the thesis shows how CSR-oriented pay regulation is consistent with the conventional goals of corporate governance and eventually provides a prospect for the integration of CSR and corporate law in general.

Water, sediment and soil physicochemical interactions in freshwater, brackish and saline systems

The physicochemical interactions between water, sediment and soil deeply influence the formation and development of the ecosystem. In this research, different freshwater, brackish and saline subaqueous environments of Northern Italy were chosen as study area to investigate the physicochemical processes which occur at the interface between water and sediments, as well as the effects of soil submergence on ecosystem development. In the freshwater system of the Reno river basin, the main purpose was to define the heavy metals hazard in water and sediments of natural and artificial water courses. Heavy metals partitioning and speciation allowed to assess the environmental risk linked to the critical action of dredging canal sediments, for the maintenance of the hydraulic safety of plain lands. In addition, some bioremediation techniques were experimented for protecting sediments from heavy metals contamination, and for giving an answer to the problem of sediments management. In the brackish system of S. Vitale park, the development of hydromorphic and subaqueous soils was investigated. The study of soil profiles highlighted the presence of a soil continuum among pedons subjected to different saturation degrees. This investigation allowed to the identification of both morphological and physicochemical indicators, which characterize the formation of subaqueous soils and describe the soil hydromorphism in transitional soil systems. In the saline system of Grado lagoon, an ecosystem approach was used to define the role of water oscillation in soil characterization and plants colonization. This study highlighted the close relationship and the mutual influence of soil submergence and aeration, tide oscillation and vegetation cover, on the soil development. In view of climate change, this study contribute to understand and suppose how soil and landscape could evolve. However, a complete evaluation of hydromorphic soil functionality will be achieved only involving physiological and biochemical expertise in these kind of studies.
