The role of the Magellan Strait on the southwest South Atlantic shelf
No full textWe analyze historical hydrographic data together with recent high-resolution hydrographic and underwater glider observations collected in the Magellan Strait to determine the water mass characteristics and exchanges between the continental shelves of the southeast South Pacific and southwest South Atlantic around southern South America. The near-surface salinity distribution and water mass analyses indicate a strong interoceanic connectivity associated with diluted subantarctic waters of the Pacific Ocean through the Magellan Strait which in turn are further diluted largely by inflows from the Almirantazgo Fjord via the Whiteside Channel. The lowest salinity waters reach the Atlantic shelf via the Magellan Strait. This core of low salinity waters (S < 31.5) are observed on the northern portion of the strait's Atlantic mouth and creates a strong baroclinic signal that leads to intense eastward geostrophic velocities suggesting a net Pacific to Atlantic transport (0.038–0.074 Sv, 1 Sv = 106 m3 s−1). This flow plays a significant role on the thermohaline characteristics and extent of the subantarctic shelf waters that occupy the Atlantic shelf. The low salinity inflow from the Magellan Strait combines with saltier inflows through the Le Maire Strait and farther east that feed the Atlantic shelf.Fil: Brun, Anahi Amaru.

Changes in hippocampal Arc protein expression and synaptic plasticity by the presentation of contextual cues linked to drug experience
No full textContextual cues linked to drug experience have been frequently associated to craving and relapse, with this phenomenon being described in human and experimental animals. Hippocampal synaptic plasticity has been related to learning, memory, and adaptive processes developed during chronic administration of drug abuse. In this study, we investigated if the environmental context associated with withdrawal experience was able to evoke the same behavioral alteration observed after chronic benzodiazepine administration. Furthermore, we studied the hippocampal synaptic plasticity and anatomical expression of Arc protein during withdrawal and the re-exposure to the context associated with anxiety expression (characteristic sign of benzodiazepines withdrawal). It was demonstrated that re-exposure evoked on days 15 and 25 after the first exposure the same behavior. An increased hippocampal synaptic plasticity, expressed as a lower threshold to induce long-term potentiation on dentate gyrus, was observed in animals dependent on diazepam and during retrieval, in the same group, until day 15. This plastic change disappeared 25 days after the first exposure. An overexpression of Arc protein in the dorsal dentate gyrus and CA1 on the first day of withdrawal in the dependent animals was observed.Fil: Monti, María Carolina.

Mapping the Horizon of Transformative Peace
No full textThis article explores what it means for peace to be transformative and discusses what it takes for a peace project and its institutions to enable transformative peace. To address these questions the article offers a theoretical and conceptual approach and draws on< some examples from case studies, especially Colombia. The article deals with the resistance that transformative projects might face from the victims they are meant to benefit. It promotes an understanding of conflict and resistance as essential dimensions to bring about positive transformations in violent contexts. In so doing, the author shows that the possibilities offered by normative-based frameworks to build transformative peace are curtailed by principles such as neutrality and impartiality of international law. These principles have resulted in institutional gender and race blindness that precludes the possibilities of a peace project being transformative.Thus, she offers a debate on two aspects that might condition or enable transformative forms of peace: the temporalities of peacebuilding and the inclusion of dissensus. Building on this the author proposes an understanding of transformative peace as an orientation that has on its horizon people’s emancipation from structural oppressions. This understanding will allow peace institutions more realistic time-space scales and the opportunity to benefit from the difference and dissensus that the practice of peacemaking might have left aside.Sonia Garzon Ramirez holds a PhD in Comparative Gender Studies from the Central European University, Budapest (Hungary). From 2020 to 2022, Sonia was a Marie Skłodowska-Curie postdoctoral fellow at the Department of International Politics, Aberystwyth University (UK). In 2021, she was a visiting researcher at swisspeace with the Dealing with the Past (DwP) team. Her current research examines nonviolent resistance and contestation to peacebuilding. Sonia combines feminist theory, intersectionality and agonistic theory to investigate how dissensus participates in shaping peacebuilding and bringing about transformative peace
Biodiversity and biogeography of hydrothermal vent species: thirty years of discovery and investigations
No full textAuthor Posting. © Oceanography Society, 2007. This article is posted here by permission of Oceanography Society for personal use, not for redistribution. The definitive version was published in Oceanography 20, 1 (2007): 30-41.The discovery of hydrothermal vents and the unique, often endemic
fauna that inhabit them represents one of the most extraordinary
scientific discoveries of the latter twentieth century. Not surprisingly,
after just 30 years of study of these remarkable—and extremely
remote—systems, advances in understanding the animals and microbial
communities living around hydrothermal vents seem to
occur with every fresh expedition to the seafloor. On average, two
new species are described each month—a rate of discovery that has
been sustained over the past 25–30 years. Furthermore, the physical, geological, and
geochemical features of each part of the ridge system and its associated
hydrothermal-vent structures appear to dictate which novel
biological species can live where. Only 10 percent of the ridge
system has been explored for hydrothermal activity to date (Baker
and German, 2004), yet we find different diversity patterns in that
small fraction. While it is well known that species composition varies
along discrete segments of the global ridge system, this “biogeographic
puzzle” has more pieces missing than pieces in place.E. Ramirez-Llodra is supported by

On the taxonomic status of Liolaemus filiorum Pincheira-Donoso & Ramirez, 2005 (Iguania: Liolaemidae): A response to Pincheira-Donoso
No full textArtículo de publicación ISII discuss the arguments put forth recently by Pincheira-Donoso, in which the author attempts to revalidate Liolaemus filiorum Pincheira-Donoso & Ramirez, 2005, a species which I had previously considered a junior synonym of L. puritamensis. The author of this revalidation omitted important information including: 1) the description was published without peer review, 2) one of the two types was deposited in a personal collection, 3) the diagnosis is weak and unclear, 4) the holotype was not explicitly described or illustrated. Additionally, the author did not discuss key aspects of my paper, most particularly, the incorrect designation of the holotype of L. filiorum
The port in the storm: Mario Ramirez, Hurricane Beulah, and the lower Rio Grande Valley
No full textThe author has granted permission for their work to be available to the general public.This historical analysis focuses on the Lower Rio Grande Valley, particularly Starr County. It reviewed thousands of pages of archival records, historical news reports, feature profiles, city, state, and federal government documents, interviews, videos, and academic examinations. This thesis borrows biographical, narrative, and borderlands history approaches to portray Dr. Mario E. Ramirez as a man who believed that he could make a difference in many Valley lives. It argues and demonstrates that he successfully and repeatedly realized that belief throughout the fields of medicine, politics, and education. The thesis examines 1967's Hurricane Beulah as a dramatic example of how Ramirez --who assumed a leadership role in the medical relief efforts on both sides of the Rio Grande -- utilized his community standing, his professional standing as a South Texas doctor, and his familiarity with a predominantly Mexican-American population to improve his Starr County community. The Beulah relief efforts enhanced his image as a role model, as a legitimate community voice, and as a state and national representative of Valley needs. Ramirez's political and professional achievements enabled him to guide thousands of Valley residents into medical careers. Many of them returned to the Valley, as he did, to care for their communities. His ambitions also made him a cornerstone of efforts to build and strengthen medical education and health care throughout South Texas.Histor
