Simple Summary: This study was conducted to estimate the rate of Salmonella spp. isolation from cage papers, located in the bottom of canaries' cages and those of other exotic pet birds, in the 2015 Argentinean canary breeder championship. Furthermore, we determined the antimicrobial resistance profile of the isolates for antibiotics and commercial disinfectants. One pool of 258 cage paper pools was positive for Salmonella spp. (0.4%). Two strains of Salmonella serotype Glostrup were isolated, which were only resistant to sulfonamides and erythromycin and sensitive to alkali-based product PL301 AS. Although the rate of Salmonella spp. isolation from cage papers in an Argentinean canary breeder championship is low, this is the first study conducted in Argentina on Salmonella spp. isolation from these materials of pet birds. However, Salmonella ser. Glostrup isolated strains could be a source of human Salmonella outbreaks, and they show high resistance to disinfecting products. Birds, including canaries and other birds, have become increasingly popular as pets. Bird fairs, where breeders gather and show their production in a championship setting, present a setting for possible Salmonella spp. contamination and transmission. Therefore, this study estimated the rate of Salmonella spp. isolation from cage papers, located in the bottom of cages of exotic pet birds, including canaries. Collected Salmonella isolates were used to determine the antimicrobial resistance profile to 52 antibiotics and 17 commercial disinfectants, based on pure or a mixture of acids, alcohols, aldehydes, alkalis, halogens, peroxygen, and quaternary ammonium compounds. The samples consisted of 774 cage papers taken in the 2015 Argentinean canary breeder championship, pooling three cage papers into one sterile sampling bag. Only one pool of the cage papers was positive for Salmonella spp. (0.4%), which belonged to the sample from three frill canary cages. Two strains of Salmonella serotype Glostrup were isolated, which were only resistant to sulfonamides and erythromycin and sensitive to alkali-based product PL301 AS. Although the rate of Salmonella spp. isolation from cage papers in an Argentinean canary breeder championship is low, it should not be discounted because Salmonella ser. Glostrup can be a source of human Salmonella outbreaks and they show high resistance to disinfecting products. [ABSTRACT FROM AUTHOR]

This study proposes a methodology using OpenAlex (OA) for tracking Open Access publications in the case of Argentina, a country where a self-archiving mandate has been in effect since 2013 (Law 26.899, 2013). A sample of 167,240 papers by researchers from the Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) was created and analyzed using statistical techniques. We estimate that OA is able to capture between 85-93% of authors for all disciplines, with the exception of Social Sciences and Humanities, where it only reaches an estimated 47%. The availability of papers in Open Access was calculated to be 41% for the period 1953-2021 and 46% when considering exclusively the post-law period (2014-2021). In both periods, gold Open Access made up the most common route. When comparing equal periods post and pre-law, we observed that the upward trend of gold Open Access was pre-existing to the legislation and the availability of closed articles in repositories increased by 5% to what is estimated based on existing trends. However, while the green route has had a positive evolution, it has been the publication in gold journals that has boosted access to Argentine production more rapidly. We concluded that the OA-based methodology, piloted here for the first time, is viable for tracking Open Access in Argentina since it yields percentages similar to other national and international studies.

Lactation is a crucial reproductive stage in eutherian mammals and the most energetically and nutritionally expensive part of the life cycle. However, data on lactation parameters in cetaceans remain scattered and incomplete. In this paper, we present novel information on the nutritional compositions and fatty acid (FA) profiles of the milks of two small odontocete species that inhabit coastal waters of the southwest Atlantic Ocean: the endangered Franciscana dolphin (Pontoporia blainvillei) and the Burmeister's porpoise (Phocoena spinipinnis). Milk samples were collected from the fresh carcasses of two lactating females stranded in Argentina. The milk profiles of both species were consistent with existing knowledge on odontocetes worldwide, being characterised by low proportions of carbohydrates and high proportions of proteins and lipids. The FA profiles exhibited a predominance of long-chain FAs (≥18 C), with monounsaturated FAs representing nearly 50% of the total FAs. In both species, the main FAs were 18:1n9 and 16:0, which are common FAs in coastal prey species in this region. These findings are particularly relevant for the conservation of Franciscana dolphins, which are at risk of extinction throughout their distribution range. [ABSTRACT FROM AUTHOR]

This paper presents the results of a study on the isotopic ecology of guanacos in central western Argentina. We examine the historical population ecology of guanacos using stable isotope analysis of bone collagen from pre-Hispanic and modern guanaco populations (n = 129), considering variability in two ecoregions: the Monte hot desert and the Andean-Patagonian cold desert. Our study addresses the consistency of guanaco diets over time, evaluating palaeoecology to provide information for conservation of this taxon. We found significant differences in isotopic niche size between modern and archaeological guanacos. When analyzed by ecoregion, there were significant differences in niche size through time, indicating that guanacos had distinctive dietary habits and occupied different ecological niches across the ecoregions. Comparing Standard Ellipse Areas (SEA) through time and across space, we observed that the archaeological SEA for guanacos is smaller than its modern counterpart in the Andean-Patagonia ecoregion. Conversely, in Monte, the archaeological SEA is larger than the one established for modern samples. The contrast between pre-Hispanic and modern populations highlight the impact of human activity and conservation efforts on the distribution and ecology of guanacos. These findings have important implications for understanding guanaco ecology with consequences for conservation policies. [ABSTRACT FROM AUTHOR]

Argentina has a history of tumultuous agreements with the International Monetary Fund. While the IMF has provided essential economic support, their loan agreements have often caused further economic issues that most profoundly impact the middle and working class, such as high inflation and poverty rates. This has created much frustration among the people, and they have taken these frustrations into music, protesting the damage and harm that is produced by the IMF's involvement in Argentina. These protest songs can be analyzed through Jeneve Brooks' EMM-framing theory, with EMM standing for emotive, moral, and mnemonic, to understand how the IMF is negatively represented and how the songs can influence the public's opinion on the IMF. This paper makes use of this theoretical framework to analyze three examples of Argentine protest songs against the IMF: "Estoy tocando fondo" by Viuda e Hijas de Roque Enroll,"F.M.I. (Sufre Sudamérica)" by Fun People, and "Sinceramente militamos" by La Cámpora. This analysis provides insight into the increasing reactiveness of the Argentine people against the IMF, which was witnessed in 2021 and 2022 when protests broke out over negotiations between the IMF and the Argentine government even though an agreement had yet to be made.

This paper attempts to study the dynamics and influencing factors of China-Argentina cooperation in the multilateral framework from a multidimensional theoretical perspective, in order to reveal the external thrust and internal logic of the development of Sino-Argentine relations. The four theories discussed in the paper are not opposed but complementary to each other. Together, they explain the factors that drive and hinder Sino-Argentine cooperation at the multilateral level. This article also presents a study of Sino-Argentine cooperation practices at three different levels of multilateral platforms, namely the UN General Assembly and Security Council, the G20 and the China-CELAC Forum. Cooperation between China and Argentina in multilateral mechanisms not only helps communication, understanding and coordination of positions between China and Argentina on major international issues, but also contributes to jointly enhancing the voice and influence of developing countries in international affairs.

In Central Western Argentina (CWA), the incorporation of cultigens by hunter-gatherer populations has been much discussed. This paper explores the relationship between population dynamics, subsistence change, and burial patterns driven by the process of land use intensification and increasing reliance on maize. We hypothesize that territorial behavior emerged in the context of population growth and competition for resources with a high probability of failure, as expected in an arid environment. To evaluate this hypothesis, we explore four lines of inquiry in southern Mendoza (CWA): 1) the frequency of radiocarbon dates to estimate population dynamics; 2) the Juvenile Index as a fertility rate proxy; 3) the stable isotopes on human bone (δ 13C co , δ 15N, δ 13C ca) to reconstruct diet; and 4) burial patterns as an estimate of territorial control. Our results partially support our hypothesis: During an early stage, when maize started to appear in the diet, the population was increasing, and cemeteries emerged along with some signs of violence. The hypothesis is not supported in a second period, when maize consumption and population were highest, but large cemeteries disappeared. In light of this evidence, the effect of maize on human societies was not uniform and irrevocable, and the adoption of maize by human foragers contributed to a new and diverse set of human-environment relationships.

The Finochietto thoracic retractor is a familiar instrument to most surgeons. The contributions to surgery of its inventor, Argentinean surgeon Enrique Finochietto and his brother, Ricardo Finochietto, extend far beyond a single instrument. This paper reviews their careers and legacy. Both brothers were part of an international network of elite surgeons. Their contributions are reflected in the number of instruments and eponyms associated with their name. [ABSTRACT FROM AUTHOR]

This article proposes to review the categories through which the study of the relationship between national identities and football was founded in Latin America, especially those of "public arena", inspired by the work of Clifford Geertz, and that of "free zones" of a culture, introduced by the Argentine anthropologist Eduardo Archetti to investigate the foundation of a "popular sporting nationalism" in the early twentieth century. To this end, it examines the ways in which Argentina's recent victory in the Qatar 2022 World Cup was narrated in television accounts and in the experience of fans, as well as the vicissitudes of its (impossible) political capture. Finally, the paper explores the shift from political hero to post-political hero: the narrative games that make the passage from Maradona to Messi possible. [ABSTRACT FROM AUTHOR]

This paper examines the behaviour of credit rating agencies (CRAs) during the ebbing 'pink tide'. It claims that the actions of S&P Global, Moody's and Fitch contributed to dismantling left-wing regimes in Latin America, to the benefit of their right-wing competitors. The methodology draws on case studies of Brazil and Argentina, where the governments of Dilma Rousseff and Cristina Fernández de Kirchner were replaced by those of Michel Temer and Mauricio Macri, respectively. The research is based on sovereign ratings, reports and press releases the agencies issued during those transitions, which are analysed in the light of critical theories of their modus operandi and confronted with the political processes unfolding in both countries. This allows us to draw conclusions that are consistent with the presented argument, thereby contributing to advance the research agenda around the CRAs and to shed light on Brazil and Argentina's recent critical presidential transitions.

Based on China's multilevel engagement strategy in Latin America and the Caribbean, this paper seeks to investigate Argentina's subnational strategies towards the Asian giant in terms of energy transition in two areas: the production of renewable energies and the production of lithium as a storage medium. The perspectives of asymmetric interdependence and structuralism are used to explain the pattern of links between the two countries; and studies of paradiplomacy are used to understand the international actions of Argentina's provinces. The analysis focuses on energy initiatives between 2014 and 2023, using a qualitative methodology with case studies. The initial argument maintains that the development of clean energy is a complementary interest between the Argentine provinces and China, as the Asian country builds its leadership in the field of energy transition, and the provinces diversify their local production matrices.
