Researcher Dennis E. Muñoz Ramírez has become the first person with severe visual impairment to defend a doctoral thesis at the Universitat Jaume I in Castelló. The doctoral student of the Doctoral Programme in Economics and Business has had the support of the Diversity and Disability Unit (UDD) of the UJI, ONCE and the ONCE Foundation, which has guaranteed inclusion throughout the defense process.

The accompaniment and support provided by the UDD (which belongs to the Vice-Rector's Office for Social Responsibility, Inclusive Policies and Equality) had already begun during her time as an undergraduate student, at the beginning of her academic career at the public university of Castelló (with technical assistance to the teaching staff or adaptations to the materials of the Virtual Classroom), always in collaboration with ONCE, with whom the UJI has been working since 1994.

The defense of Dennis Muñoz's thesis is the first to be carried out within the framework of the UDD's monitoring and support of doctoral students. She has had additional technical resources (to facilitate the projection of the slides from the doctoral student's adapted device), support staff (a volunteer has provided assistance), and additional time.

In addition, all the information necessary for adaptation to these needs has been provided to the Doctoral School, the examining board and the codirectors, to guarantee the right of the doctoral student to carry out the defense under conditions of full equality and in line with the commitment of the Universitat Jaume I for equal opportunities for people with disabilities and full inclusion, recently renewed by the approval of its Plan for Inclusion and Non-Discrimination.

**THE IMPACT OF DISSEMINATION ON CORPORATE SUSTAINABILITY**

The thesis "Impacto de la divulgación sobre sostenibilidad en la dimensión medioambiental en los informes no financieros de las empresas europeas que utilizan la metodología GRI para su elaboración y publicación" [Impact of sustainability reporting on the environmental dimension in the non-financial reports of European companies that use the GRI methodology for their preparation and publication] was directed by David Cabedo Semper and José Miguel Tirado Beltrán, from the HAGAS - Social Dimensions of Finance, Economics and Accounting research group of the Faculty of Legal and Economic Sciences.

The work analyzes the impact of environmental disclosure in the non-financial reports of European companies prepared with the GRI methodology (a set of internationally recognized principles and guidelines on sustainability aspects). For this reason, it has examined the reports of chemical, energy and electricity companies for the year 2018 with a computational analysis tool, DICTION, proposing a measure of compliance, the Environmental Disclosure Index (EDI).

Conclusions indicate that companies strictly disclose what is required by regulations in a neutral tone (neither optimistic nor pessimistic), although the level of certainty detected in the tone of the information makes it difficult to evaluate environmental development and also calls transparency into question. In addition, a positive and statistically significant relationship is detected between disclosure and the environmental risk of operations. The research recommends more stringent regulations to promote sustainability and corporate transparency.
