Documenting the Experiences of Gay Latinos in Higher Education through the use of Testimonio

This qualitative study focuses on the stories of six self-Identified Gay Latinos in a higher education. The participant’s stories are documented using Testimonio. The six men were uniquely situated to give their testimonios about their campus experiences of seeking support in that they were the narrators of the experiences. Key findings indicated a pipeline of support which began with supportive families. Multidimensional identity was well defined by the participants as understanding of being both Latino and Gay. The participants, while exploring campus spaces for support, found themselves navigating through one identity or the other resulting in a process of selective identity. Ultimately, the participants made decisions about safe-supportive spaces based on how they identity. Certain spaces such as LGBTQ resources did not meet their multidimensional needs. All participants found support with one or more campus resource from which they could identify as Latinos, but not necessarily as Latino and Gay men. The testimonios in this study allowed for deep exploration of the participants campus experiences of support. Their stories allowed for a theoretical analysis through the frameworks of Critical Race theory, Latino Critical Theory, and Queer Critical Theory. These stories can serve to inform higher education about the needs of LGBTQ students of color

Italy Is Fragile: Soil Consumption and Climate Change Combined Effects on Territorial Heritage Maintenance

The article looks for relations between growth of expanding cities, number of catastrophes and reduction of inhabitants in inland regions. The study explores these aspects through cartographic readings aimed at highlighting the relationship between soil consumption, the abandonment of peripheral areas, and environmental risks due to floods, landslides and earthquakes. The research analyzes the whole of Italy as a case study between 1990 and 2019 to get an accurate interpretation of the relations between these phenomena. The conclusions alert us to the need to redirect Italy\u2019s development and its resilience projects. The study outlines the need of a re-living plan for Italian inner areas. It would be the only security process really capable of taking care of the territory

Rethinking planning hierarchy considering climate change as global catastrophe

This article proposes overcoming the distinction between the effects of climate change and the effects linked to classical disaster hazards by considering Climate Change as global catastrophe. The theoretical approach to combining the two models has until now greatly emphasized the need for further research, but with poor results. Starting from a new conception of climate change as a catastrophe in progress, the paper proposes a revision of local planning hierarchy in order to give a primary role to risk assessment in every sector of local development

Integrability of 1D1D Lindbladians from operator-space fragmentation

We introduce families of one-dimensional Lindblad equations describing open many-particle quantum systems that are exactly solvable in the following sense: $(i)$ the space of operators splits into exponentially many (in system size) subspaces that are left invariant under the dissipative evolution; $(ii)$ the time evolution of the density matrix on each invariant subspace is described by an integrable Hamiltonian. The prototypical example is the quantum version of the asymmetric simple exclusion process (ASEP) which we analyze in some detail. We show that in each invariant subspace the dynamics is described in terms of an integrable spin-1/2 XXZ Heisenberg chain with either open or twisted boundary conditions. We further demonstrate that Lindbladians featuring integrable operator-space fragmentation can be found in spin chains with arbitrary local physical dimension.Comment: 8 pages, no figures; v2: minor revisio

Hydra-Amoeba system: a double infection with a lethal ending

Within each ecosystem, organisms and populations maintain a complex set of relationships. These interactions can determine the distribution area of a species and play an essential role in its evolution. Parasites are ubiquitous components of nature and have a high influence on various aspects of the biology and ecology of organisms, affecting the populations of their hosts and, therefore, their communities and ecosystems. Free-living amoebae are unicellular organisms that can be found in water, soil or air. Some species are of great importance in human health. In Hydra, there are several reports of Hydramoeba hydroxena infections. In this work we present a double parasitosis: two concatenated infectious periods in the host polyp of Hydra vulgaris and Hydra vulgaris pedunculata for three freshwater bodies in the province of Buenos Aires, Argentina. Hydramoeba sp. and Acanthoamoeba sp. unchain a series of anatomical lesions that in all cases cause the death of the polyps due to total disintegration. This finding becomes important at a sanitary level due to the appearance of Acanthoamoeba sp. in waters associated with human recreational activities; For the Hydra genus, the importance lies at an ecological and evolutionary level, considering the possible impact on its natural populations.Fil: Deserti, Maria Irene.

On a procedure to derive ϵ\epsilon-factorised differential equations beyond polylogarithms

In this manuscript, we elaborate on a procedure to derive $\epsilon$-factorised differential equations for multi-scale, multi-loop classes of Feynman integrals that evaluate to special functions beyond multiple polylogarithms. We demonstrate the applicability of our approach to diverse classes of problems, by working out $\epsilon$-factorised differential equations for single- and multi-scale problems of increasing complexity. To start we are reconsidering the well-studied equal-mass two-loop sunrise case, and move then to study other elliptic two-, three- and four-point problems depending on multiple different scales. Finally, we showcase how the same approach allows us to obtain $\epsilon$-factorised differential equations also for Feynman integrals that involve geometries beyond a single elliptic curve.Comment: 52 page

Albedo Urbis : Bianchezza e capacit\ue0 adattiva dei centri storici all'isola di calore

Fra le propriet\ue0 da considerare nei processi di adattamento della citt\ue0 al cambiamento climatico il colore e la natura delle superfici stanno assumendo un ruolo di sempre maggiore rilevanza. L\u2019albedo \u2013 la bianchezza dei materiali \u2013 \ue8 la propriet\ue0 che hanno le superfici caratterizzate da un colore chiaro di riflettere la radiazione solare e, con essa, il calore ricevuto. Con una particolare attenzione alla cromia del centro urbano consolidato, la ricerca prova ad esplorare le ricadute per le nostre discipline dei diversi aspetti della fisica tecnica e dell\u2019ingegneria ambientale che partecipano al contrasto ai fenomeni di \u201cisola di calore\u201d. Tali aspetti tecnici contribuiscono, retrospettivamente, a rileggere le razionalit\ue0 costitutive che si sono depositate nel centro storico definendone nel lungo periodo i criteri generativi e, prospettivamente, ci spingono a individuare gli strumenti di un possibile nuovo progetto di adattamento del patrimonio storico a condizioni ambientali che con il clima sono oggi in profonda mutazione
