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]

In accordance with global migration trends, Russian geography became a source of emigration starting from the mid-19th century. On the other hand, following their independence in the early 19th century, Latin American countries became recipients of migration waves from different countries, including multinational Eurasian states such as Ottoman, Russian, and Austria-Hungarian empires. The migration wave from Russian Empire to Latin America started around the 1850s and lasted until the collapse of the empire in 1917. Argentina was the leading destination of emigration for the early migrant Russian citizens who were then officially called the “Ruso” and came from various ethnic and religious backgrounds. Within the context of this paper, which focuses on the migration and adaptation processes of Ruso immigrants in Argentina, the social, economic, cultural, and religious dimensions of their new lives are discussed. The paper concludes that early Ruso immigrants eventually constituted a labor diaspora and, despite being ethnically and religiously the most heterogeneous migrant movement from the Russian geography, Russian language, and culture continued their dominancy in the lives of at least the first immigrant generation.

This paper analyses slavery in the Les Malouines/Las Malvinas/Falklands Islands to advance the historical study of the geographies of race in Argentina with reference to marronage and critical place naming. These islands are an example of an assemblage of colonial military extractive powers. There still are disputes with Argentina since the armed conflict of 1982. However, Las Malvinas were a part of the Spanish Empire since the French colonial authorities sold this territory in 1766. Despite being seen as at the margins of this Empire, an infertile terrain with unbearable weather, and a place of punishment for those who defied colonial rule, it was of strategic value, expensive but worth maintaining to keep the British Empire removed from Buenos Aires and Montevideo. To reduce the islands' expenses, the plan was to relocate recaptured fugitives to this territory as a labour force. Archival records collected from the National General Archive of Uruguay, General Archive of the Indies, and National Historical Archive of Madrid show that Las Malvinas were not exempt from slavery. In 1770, Antonio and Miguel, ‘royal slaves’, were part of the islands' population among white Europeans and indigenous people held captive there. They were allowed to leave the islands to live and serve the King and they navigated through the ports of Montevideo and Buenos Aires, where their tracks end. This paper demonstrates how this insular space, meant for penance, was also a place where resistance linked with marronage broke an assemblage of colonial military powers. It also highlights that the historical geographies of slavery in Argentina are intrinsically assembled with the dispossession of indigenous and other disadvantaged groups proposing an Afro‐Marrón approach to their analysis with a potential extension to other racialised Latin American geographies.

The aim of this article is to outline an overview and to discuss some constraining factors related to teaching Spanish as L1 in the context of linguistic diversity in Argentina. The underlying argument of this paper is that diverse school materials and teaching methodology involved in teaching Spanish as L1 neglects linguistic diversity. Instead, they subscribe to discourses that reinforce a pyramidal normative structure where the Spanish Royal Academy is the apex, and therefore, so is its linguistic authority. Our suggestion in this regard is that the diversity of voices must have a space not only in the classroom and materials, but also in research processes and academia's knowledge management. For this purpose, and framed within a glotopolitical approach, this paper analyzes, firstly, the obstacle represented by the fixed categories included in school curriculum such as "language", "variety", "standard", and even "national language"; secondly, the paper reviews the role played by grammatization instruments (such as dictionaries and school textbooks, among others) and their monologic discursive wording. Finally, the article suggests didactic strategies to analyze linguistic varieties in class, and to reinforce a critical reading of norm distribution instruments. [ABSTRACT FROM AUTHOR]

Knowledge from customers, suppliers, competitors, universities, is a key input in the innovative process of firms. However, firms must have absorption capacity to take advantage of such external knowledge. Based on the concept of absorptive capacity, this paper aims to analyze the impact that knowledge spillovers have on obtaining technological innovations by industrial firms located in Argentina and explore the moderating role that the absorption capacity exerts on such impact. Knowledge spillovers are one of the mechanisms or channels for access to external knowledge by firms. In this paper, such knowledge spillovers are captured through the concept of external sources of information. The external sources of information are differentiated into market, academic and general sources. After applying the Oaxaca-Blinder gap decomposition technique, no results are found in favor of a moderating effect of the absorption capacity for any of the external sources of information analyzed. Limitations, future directions, and policy implications are discussed. [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.

This article examines how trauma and affective injustice permeate the school life trajectory of a female student (Sofia) in Argentina. The study is theoretically grounded in the field of trauma studies in education and contributes to this literature by attending to affective injustice, a concept that has not received much attention yet. This study foregrounds Sofia's experience of affective injustice and demonstrates that this concept is crucial in further understanding students' experiences of affective trauma in school. Assembling rich materials (report cards, interviews, psychologists' reports, social media posts, autobiographical texts) that span over a period of 17 years, the study uses qualitative perspectives to show how Sofia understands and experiences affective injustice in various phases of her school life. In particular, these experiences are presented in the form of an assemblage of expressions showing how Sofia communicates her claims of affective injustice using varied means and resources ranging from linguistic, behavioural, biographical, creative, emotional, bodily, and artistic expression. The paper concludes with a discussion of the educational implications of the study. [ABSTRACT FROM AUTHOR]

The influence of the International Baccalaureate (IB) has grown impressively on a global scale. In Latin America, the IB has been mainly introduced in private schools that cater for the most affluent sectors of society and, consequently, has been mostly interpreted as contributing to processes of social reproduction and the widening of inequalities However, since the mid-2000s the IB has been promoted in state schools in countries such as Ecuador, Peru, Costa Rica and in the City of Buenos Aires in Argentina. This paper analyses the enactment of the IBDP in public schools in Costa Rica and Peru drawing on a mixed methods multiple case study. It shows how, in countries with significant socioeconomic disparities, the possibility of offering the IBDP to students at public schools was mostly justified as a matter of equity, understood as opening access to an educational programme that was only available to the most privileged sectors of society. By problematising the notions of privilege and eliteness, we discuss the complex relations between inequalities and educational opportunities and question the extent to which these programmes are affecting social structures in Costa Rica and Peru.

The paper explores the intricate character of public urban spaces, unveiling their almost contradictory nature as both a source of gendered fear and as potential spaces where subjects gain political visibility through collective interventions. Globally, nearly 90 per cent of young women below 30 years of age report feeling unsafe in public spaces. Despite the fear of public spaces, feminist mobilisations, exemplified in the paper by the dynamic movements for women's rights in Argentina between 2015 and 2022, carry the potential to reclaim public spaces. The research examines the Ni Una Menos (Not One [Women] Less), the National Campaign for the Right to Legal, Safe and Free Abortion, and the Plurinational Meeting of Women and Dissidents protests to understand young women's experiences of political mobilisations. I introduce the concept of 'subversive visibility' to capture instances where public spaces become fear-pacifying rather than fear-inducing spaces, disrupting traditional gendered spatial logic. The disruptions in the form of protests and occupations challenge the conventional division of private and public spaces, showcasing transformative potential. The paper employs theoretical perspectives on the gendered implications of the public–private binary, urban safety, and draws on scholarship related to massive protests and women's rights struggles.

The palaeofauna of the Quaternary is mostly known from the mammals' record, while the herpetofauna is less represented. In the same way, in northeastern Argentina reptile fossils records are scarce, usually represented by preliminary communications. This paper focuses on the study of herpetofauna remains from the Isla El Disparito archaeological site. The faunal materials collected at the site revealed an increase in taxonomic diversity related to the Quaternary herpetofauna in the IED site, with over 50% of the bone remains represented by anurans and at least six recognized squamates taxa. The purpose of this study is to properly identify these new records of herpetofauna remains from northeastern Argentina during the Holocene as well as to provide a dichotomous key of postcranial remains for identifying extant squamates taxa in other Quaternary sites from Argentina. The identified squamate assemblage includes the lizard Ophiodes sp., the snake families Typhlopidae, Dipsadidae, Viperidae and undetermined colubroids, along with anuran bone remains (Anura indet. and ?Hylidae). Additionally, the findings contribute to a better understanding of the herpetological assemblage in Argentina, providing insights into the composition of South American squamates during the Quaternary.

Technologies and social networks have modified the habits of their users, affecting their health and well-being. An exponent of these affectations of daily life is the phenomenon of vamping, this is the habit in which people use their mobile or computer during the night and early morning, with the consequence of symptoms such as insomnia, fatigue, and mood swings in those who practice it. In this paper, we propose a scale to assess the tendency to vamping in adults, for its validation in the Argentine context. With a sample of 1004 cases, whose mean age was 44.29 years (SD = 11.73) and a mean age of 18–65 years, with 51.89% (n = 521) being women and 48.11% men (n = 483). The scale showed an adequate consistency for 11 items and two dimensions. The first dimension is nocturnal habits, that is, the tendency to stay up late to surf the Internet and social networks, and the second dimension is behavioural commitment, that is, the affectation and daytime correlate caused by changes in sleep pattern.

This paper reviews the professional situation of school principals during COVID-19 in Argentina, where one of the longest school closures in the world was maintained. It analyzes the existence of burnout, concerns, constraints and needs of 252 principals at the end of the 2020 school year. The results indicate that there is a double phenomenon of Emotional Exhaustion and Personal Accomplishment, while tensions with regulations and working conditions are evidenced. We found a leadership open to the context, with greater autonomy and a strong emotional commitment, with implications and challenges for the post-pandemic future. [ABSTRACT FROM AUTHOR]

Student socioeconomic segregation is one of the main sources of educational inequity in Argentina. The objective of this paper is to study the explanatory factors of school attendance in privately managed institutions at the secondary level. Furthermore, given the differences in the participation of the private sector by provinces, we particularly aim to compare these determinants to identify possible discrepancies related to geographic location. Some evidence was found that, beyond purchasing power, various social, economic, and cultural characteristics of households are associated with the type of school attended. Moreover, it can be observed that these relationships are not totally homogeneous between the provinces. [ABSTRACT FROM AUTHOR]

Purpose: Using sentiment analysis (SA), this study aims to examine the impact of COVID-19 on mental health and virtual learning experiences among 1,125 students at a public Argentinean faculty. Design/methodology/approach: A study was conducted during the COVID-19 pandemic, surveying 1,125 students to gather their opinions. The survey data was analysed using text mining tools and SA. SA was used to extract the students' emotions, views and feelings computationally and identify co-occurrences and patterns in related words. The study also examines educational policies implemented after the pandemic. Findings: The prevalent emotions expressed in the comments were trust, sadness, anticipation and fear. A combination of trust and fear resulted in submission. Negative comments often included the words "virtual", "virtual classroom", "virtual classes" and "professor". Two significant issues were identified: teachers' inexperience with virtual classes and inadequate server infrastructure, leading to frequent crashes. The most effective educational policies addressed vital issues related to the "virtual classroom". Practical implications: Text mining and SA are valuable tools for decision-making during uncertain times, such as the COVID-19 pandemic. They can also provide insights to recover quality assurance processes at universities impacted by health concerns or external shocks. Originality/value: The paper makes two main contributions: it conducts a SA to gain insights from comments and analyses the relationship between emotions and sentiments to identify optimal educational policies. The study pioneers exploring the link between emotions, policies and the pandemic at a public university in Argentina. This area of research still needs to be explored. [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.

The Scorpion Mud Turtle (Kinosternon scorpioides) has been recognized by most recent authors to be a single species (3 subspecies) ranging from Tamaulipas, Mexico, to northern Argentina. However, recent molecular analyses have demonstrated that it is not monophyletic, but rather paraphyletic relative to other Neotropical Kinosternon. Based on extensive genetic sampling across the range of this species, a recent paper elevated the 3 subspecies (albogulare, cruentatum, and scorpioides) to species status, confirmed the divergence of Pacific and Atlantic versant populations of K. cruentatum, and recommended that both be given species status. However, the type locality of K. cruentatum is imprecise, making the allocation of the name problematic. Our study sought to determine the provenance of the type using morphometric analysis of specimens from across the range. That analysis demonstrates unequivocally that the type of K. cruentatum was collected on the Atlantic versant, likely from an eastern population. Furthermore, the analysis also revealed that the type of K. mexicanum, previously synonymized with K. cruentatum, was collected from along the Pacific versant. Hence, the name K. cruentatum should be restricted to populations in Atlantic drainages, and the name K. mexicanum should be restricted to Pacific drainages. Our analysis also indicated divergence among the 3 allopatric Atlantic versant populations, but future genetic work will be needed to determine whether they merit taxonomic recognition.

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]

The application of stable isotope analyses allows a diachronic characterisation of species habitat and feeding behaviour, information of utmost importance for zooarchaeological research. In South America, the former distribution of the guanaco (Lama guanicoe) encompassed a much larger territory than the current one. Within the Argentinean Great Chaco, only a small native population persists in Northwestern Córdoba province, Central Argentina, where it was once widely distributed. In this paper, we present the first set of dentin and collagen δ13C and δ15N values for this relict population (N = 18) along with archaeological data of guanaco specimens (N = 19) dated to the Middle and Late Holocene from the nearby Ongamira valley. Neither deciduous and permanent teeth nor males and females show marked differences within the modern samples. Both modern and archaeological guanaco δ13C values indicate a mixed diet of C3 and, to a lesser extent, C4 plants. Conversely, the δ15N values exhibit distinct signals between the Arid and the Mountain Chaco subregions. The diet breadth of the archaeological guanacos suggests the use of transitional or ecotonal environments, also reflected in the size of their isotopic niche as opposed to modern guanacos. Regarding the timing of the species retraction in the region, there is no evidence of a shift in its habitat during the period between ~4700 and 190014C years BP. We suggest their retraction probably occurred later than previously proposed in regional zooarchaeological models. [ABSTRACT FROM AUTHOR]

In this paper we study the relationships between plants and extinct megafauna by examining the characteristics of the vegetation in the central region of Argentina (i.e. Espinal, Monte, and Chaco phytogeographic regions). First, we study the size, shape, quantity, and characteristics of fruits and seeds. We also evaluate the presence of mechanical (spinescence and wood density) and chemical (secondary metabolic compounds) defenses against high rates of herbivory. Complementarily, we assess the importance these plants had for human populations, using archeological, ethnographic, and current data. A high percentage of the analyzed plants met the criteria proposed for fruits and seeds dispersed by megafauna, together with a high frequency of spinescence, high density woods, and secondary metabolites. We propose that these traits cannot be explained by the herbivory pressure of extant fauna in the area, but rather developed in interaction with currently extinct fauna. We suggest that Pleistocene megafaunal extinction had important consequences in the region due to their role as ecosystem engineers and to vegetation's characteristics, which were probably strongly shaped by megafauna activities. Among these consequences, we discuss the loss of certain interactions between these animals and vegetation, such as loss of seed dispersal mechanisms, shrub invasion, and increased susceptibility of vegetation to fire. Other effects for hunter-gatherer groups were the generation of highly regulated mobility patterns and the formation of barriers for the dispersal of prey. Finally, we also discuss the importance of these plants for human populations as food, construction material, medicines and firewood. Likewise, the role of humans as "heirs" of the megafauna in the propagation of tree and shrub species is highlighted. [ABSTRACT FROM AUTHOR]

This paper analyzes spatial and temporal changes of aridity in Argentina (1961–2022). The aridity degree, using Climatic Research Unit (CRU) monthly data, was defined through six climate types classified by De Martonne Aridity Index (DMI). Argentina presents a very arid, arid and semiarid region that extends from Puna to Patagonia, alongside two humid and very humid regions: one located in the Chaco-Pampas Plains and Mesopotamia, and another in the Patagonian Andes. Between these regions, there are subhumid areas with marked aridity variations. These structures persist over time, but advances or setbacks were observed in their bordering areas, with significant changes in the Andes (leading to more arid conditions) and the southwestern Pampas Plains (leading to more humid conditions) during the historical period. The contribution of temperature and precipitation changes to these DMI changes was quantified, indicating that precipitation modulated the DMI spatial changes, while temperature intensified or weakened the change magnitudes. The extension variations of the arid and semiarid regions in Argentina were related to three climate variability modes (El Niño – Southern Oscillation [ENSO], Pacific Decadal Oscillation [PDO] and South Atlantic Ocean Dipole [SAOD]). Significant correlations were found with PDO (r < 0) and SAOD (r > 0), which indicate that an increase in the area occupied by arid and semiarid climates are associated with PDO negative phase or SAOD positive phase. Moreover, when these phases occur simultaneously, the expansion of arid and semiarid regions is larger than under the action of an individual forcing. [ABSTRACT FROM AUTHOR]

Since the 1990s, agribusiness expansion in Argentina involved the exponential growth of pesticide use throughout the country. Pesticide exposure has become a widespread problem in rural areas and farming towns, but protests and conflicts about this issue are the exception rather than the norm. Why? Based on archival work, interviews, and ethnographic observations, in this paper, we scrutinize pesticide governance at the subnational scale to elucidate this puzzle, focusing on a) informal arrangements (face-to-face negotiations between pesticide users and people affected by them), b) juridical conflicts (lawsuits against farmers over exposure of people and crops to herbicides), and c) regulatory challenges (when rural populations and environmentalists push for local ordinances to curb pesticide exposure). We find that local cultural codes encourage informal agreements and that social inequalities prevent conflicts from arising in the public sphere. The interventions of social movements and civil society organizations (or lack thereof) and the mobilization of expertise also shape pesticide governance. Our analysis highlights that pesticide governance is context-dependent or situated, and informed by subtle but significant power asymmetries. [ABSTRACT FROM AUTHOR]

Peronism deployed, especially since the 1950s, a set of devices for the attention and care of children in Argentina, not only through schools but also through other institutions, such as development societies, cooperatives, the Eva Perón Foundation, sports clubs, among others. The new social order was central to the rhetoric of the government, and it gave children a preeminent role, as is visible in the phrase "in the New Argentina the only privileged are the children". This paper focuses on Vacaciones útiles, a film made in 1948 that shows how educational cinema reflects a view of childhood and also how public policies aimed at it. This short film was part of a larger project called Cine Escuela Argentino, a Commission of the National Council of Education for the production of film material to be shown in schools and other public institutions. What particular view did Peronism have on childhood in it? To what extent can this film be thought of as an educational cinema or as a school cinema? In which ways do films like Vacaciones útiles or public policies like Cine Escuela Argentino show the figure of the State as author? [ABSTRACT FROM AUTHOR]

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]

The characteristics of South American biomass burning (BB) aerosols transported over northern and central Argentina were investigated from July to December 2019. This period was chosen due to the high aerosol optical depth values found in the region and because simultaneously intensive biomass burning took place over the Amazon. More specifically, a combination of remote sensing observations with simulated air parcel back trajectories was used to link the optical and physical properties of three BB aerosol events that affected Pilar Observatory (PO, Argentina, 31°41′S, 63°53′W, 338 m above sea level), with low-level atmospheric circulation patterns and with types of vegetation burned in specific fire regions. The lidar observations at the PO site were used for the first time to characterize the vertical extent and structure of BB aerosol plumes as well as their connection with the planetary boundary layer, and dust particles. Based mainly on the air-parcel trajectories, a local transport regime and a long transport regime were identified. We found that in all the BB aerosol event cases studied in this paper, light-absorbing fine-mode aerosols were detected, resulting mainly from a mixture of aging smoke and dust particles. In the remote transport regime, the main sources of the BB aerosols reaching PO were associated with Amazonian rainforest wildfires. These aerosols were transported into northern and central Argentina within a strong low-level jet circulation. During the local transport regime, the BB aerosols were linked with closer fires related to tropical forests, cropland, grassland, and scrub/shrubland vegetation types in southeastern South America. Moreover, aerosols carried by the remote transport regime were associated with a high aerosol loading and enhanced aging and relatively smaller particle sizes, while aerosols associated with the local transport pattern were consistently less affected by the aging effect and showed larger sizes and low aerosol loading.

Question: Do shrubs negatively affect the germination of perennial grass species in regeneration microsites? We experimentally analyzed the effect of soils from plant patches dominated by two shrub species (Larrea divaricata and Schinus johnstonii) and their propagules on the germination of three co‐dominant herbivore‐preferred perennial grass species (Poa ligularis, Nassella tenuis and Pappostipa speciosa). Location: Patagonian Monte, Chubut Province, Argentina (42°07′ S, 64°59′ W; 43°06′ S, 65°43′ W; 42°29′ S, 66°34′ W). Methods: We conducted two simultaneous microcosm experiments. In the first experiment, we sowed perennial grass propagules of the three species alone and combined with non‐scarified shrub propagules in Petri dishes with three substrate types (filter paper, inert soil and soil from shrub patches). In the second experiment, we sowed perennial grass propagules of each species combined with scarified and non‐scarified propagules of both shrub species in Petri dishes with soil taken from plant patches dominated by L. divaricata and by S. johnstonii. Both experiments lasted 3 months. We calculated the germination proportion and mean germination time (MGT) of propagules for each perennial grass species in each treatment. Results: Propagules from neighboring shrubs had a clearer negative effect on grass germination compared with shrub soils. Shrub propagules negatively affected the germination proportion of P. ligularis and N. tenuis, and induced longer MGT in the three perennial grass species. The combination of S. johnstonii soil and propagules negatively affected P. ligularis and P. speciosa germination. The combination of L. divaricata soil and scarified propagules completely inhibited P. speciosa germination. Conclusions: Our results highlighted the complexity of interactions between shrubs with high phenolic contents (soils and propagules) and the germination of perennial grass species in arid environments. Schinus johnstonii soil and propagules had stronger effects on perennial grass germination than L. divaricata soil and propagules. The negative effects of shrubs on microsite quality and germination processes depended on the specific shrub/grass interaction. [ABSTRACT FROM AUTHOR]

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.

The shore line is the limit that separates the public water domain from the property of individuals, the criterion for its delimitation is stated by law, both in Argentina and in other countries of the world. But its practical analysis remains a matter of current discussion. In this paper, a geomorphological interpretation of the established criterion is proposed as well as a methodology for its delimitation. To achieve this, different international, national, provincial and papers on shore line works were analyzed, which allowed to establish a criterion adjusted to the natural form of the channel and to cartographically define the shore line by using products of Unmanned Aerial Vehicles (UAVs). If the waterfront is delimited on the basis of natural facts, its indubitable mark on the ground will be close to what actually belongs to the public water domain. [ABSTRACT FROM AUTHOR]

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.

This paper draws from some reflections on the relationship between power and knowledge coloniality and curricular field, since the analysis of curricular documents from Brazil and Argentine. This analysis intends to trace the coloniality elements of power and knowledge connected to the presence and the absence of Afro-Descendants and Africans in both secondary schools/highschools within an international background that fostered the visibilization of Afro-Descendant/African history and culture as well as educational policies prescribing the obligatory nature of level and extension of rights. The chosen period, 2006-2015, is characterized in the regional context by the expansion of educational rights and access at all levels and an increase in state financing, within the framework of the recognition of rights to excluded populations. In the international field, it was characterized by the gestation of the Declaration of the International Year of Afro-descendant by the United Nations Organization in 2011 and the proclamation, in 2013, of the International Decade for People of African Descent that runs from 2015 to 2024. In turn, further questions arise to propose reflections on the curricular field that may contribute to the development of an epistemology of the South. [ABSTRACT FROM AUTHOR]

This paper aims to characterise the modifications caused by the Pampas fox (Lycalopex gymnocercus) to the bones and teeth of its prey in the Espinal and Dry Chaco environments, in central Argentina. Plant remains, invertebrate remains, and vertebrate bones and teeth were recovered from a set of more than 180 faeces. From an actualistic perspective, we evaluated the taphonomic signature of this predator in the remains of snakes, birds and mammals recovered in its faeces. We achieved a high rate of taxonomical identification and recovered remains of exotic and native fauna, such as Ovis aries and Lagostomus maximus, respectively. The most remarkable aspects recorded in this taphonomic study were a high frequency of breakage, a low frequency of tooth marks (only observed in large prey), and a high frequency and intensity of digestion damage. The information generated in this study contributes to the evaluations of accumulating agents in archaeological and palaeontological sites of South America. [ABSTRACT FROM AUTHOR]

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]

What is the impact of large swings in economic policy on the risk-return trade-off faced by i nvestors? What is the impact of changes in policy regimes on investment strategies? In this paper we study the impact on returns of switches between periods of market-friendly economic policies and periods of populist policies. To quantify the impact of policy instability, we use data from Argentina--a country that has experienced frequent and very large regime changes--and find that the risk-return for individual assets and minimum variance portfolios are quite different across regimes. We then develop a dynamic model to understand optimal portfolios when investors are cognizant that regimes can change. We find that when portfolios are unrestricted, it is optimal for investors to take a large amount of risk. On the other hand, when portfolios are restricted to include only long positions, a real asset (real estate) dominates financial assets. [ABSTRACT FROM AUTHOR]

Despite significant progress has been made towards crop yield prediction with remote sensing, there exist knowledge gaps on (1) the impacts of temporal resolution of imaging frequencies on yield prediction, (2) transferability of the models among different genotypes and test sites, and (3) translation of these research developments to crop breeding that benefit farmers. Existing research predominantly provides an on-site perspective, frequently missing the complexities of real-world applications. The objectives of this paper are to investigate the transferability and generalization capabilities of yield prediction models for crop breeding across test sites located in North and South Americas. Toward that goal, we tested different machine learning techniques including Random Forest Regressor (RF), Gradient Boosting Regression (GB), and Deep Neural Networks (DNN) for soybean yield prediction with experiments conducted in different climate and growth conditions. A novel transfer learning approach was proposed for genotype selection and categorizing soybean yield for screening high-yield varieties. Furthermore, we studied the effect of temporal resolution on yield prediction, focusing on the critical development stages and optimal aerial survey frequencies for precise yield prediction using large 31,404 sample data. Results demonstrated that the combined dataset of Argentina and United States representing different climate regimes provided the highest performance with an R2 of 0.76 using RF and GB algorithms. The classification approach was proven to be most useful for crop breeding as demonstrated by accurately identifying the high-yielding genotypes. Increasing temporal sampling of key phenological stages significantly improved yield prediction. Although transfer learning yielded promising outcomes across trials within Argentina the efficacy of transferring models from Argentina to the United States was limited, attributed to significant seasonal and climate variations. This study pioneered the use of transfer learning for model adaptability in real-world breeding scenarios, training and transferring models within the South and North Americas, providing actionable insights and strategies for the breeding community, aiming to facilitate improved decision-making for agricultural productivity.

The Salado and Verde streams constitute the two main seasonally available freshwater courses that flow into the Atlantic coast of the Río Negro province (continental Patagonia, Argentina, 42° South). This would have favored their use in the past as corridors for human circulation between the coast and the interior. This paper presents the results of the technomorphological and geochemical analyses of the obsidian artifacts recovered in the area to constrain mobility. The results allow us to propose the existence of toolkit reconditioning or replacement activities, and the identification of different sources of provenance of the obsidians (Sacanana, Telsen, and Portada Covunco, distant up to 800 km from the study area), reinforcing the hypothesis of a coast–inland circulation, with the possible existence of circuits of exchange of this raw material.

The destiny of the electric vehicle (EV) marketplace will depend upon the behaviour of potential buyers and on how emerging markets allow EVs to be perceived as a mobility solution to the externalities generated by internal combustion (IC) vehicles. To this end it is important to ascertain the role played by psychological factors, along with instrumental attributes, especially among younger adults (future purchasers) in not yet mature markets. Our paper analyses and models the propensity to purchase an EV with respect to an equivalent IC vehicle. It contributes to the existing literature investigating younger adults' behaviour in an emerging market, focusing on the role of attitudes and perceptions. A stated preferences survey, built on real commercial scenarios (Renault ZOE vs Renault Clio), was designed and disseminated at the University of Cordoba (Argentina). Respondent behaviour was modelled within the random utility paradigm. First, heterogeneity among users was investigated through mixed multinomial logit formulation; The role of psycho-attitudinal factors was then explored through the specification of hybrid choice models with latent variables. Estimation results indicate the significant role of attitudes and perceptions in emerging markets. [ABSTRACT FROM AUTHOR]

The interplay of digital technologies and inequalities are increasingly discussed in contemporary research, mostly focusing on different forms of digital divides and often addressed as a 'problem' that societies should face. Hence, digital education and its governance becomes a major arena for addressing inequalities. In this paper, we offer a cross-country and multi-voiced perspective on how socio-digital inequalities are problematized in digital education policy in three world regions – Latin America, Africa and Europe – studying cases through policy documents in Argentina, Mexico, South Africa, Botswana, Germany and Sweden. Our analysis shows how differences and similarities between digital education policy are rooted in various sociotechnical imaginaries that go beyond the national as they are highly situated in spatial–temporal contexts and rooted in historical trajectories. Our contribution aims at a further exploration of the entanglements of educational technology and in/equalities through global conditions and local (hi)stories. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic has produced controversies, and its mode of concrete social existence is strongly assembled in multiple ways of world-making that mobilize particular human-non-human relations. This paper analyzes the ways in which the people of the Andean valleys of northwestern Argentina understand and live the pandemic, in the partial coexistence of ways of understanding the body, the person, and wellbeing. On the one hand, we identify the so-called traditional way of life, which implies a relational sociality; on the other hand, the Pentecostal way of life, which promotes an interpretative current under an apocalyptic key. In sum, we are interested in thinking about the coexistence and assembly between ways of living suffering and well-being in the context of the pandemic, associated with expanded and relational socialities and with ways of imagining and living the "end of the world" as a specific manifestation of the Pentecostal tradition. Thus, the article proposes to overcome the perspective of COVID-19 as a given and universal phenomenon that produces different interpretations or cultural fictions, and consider it as a component in a wide network of human and non-human agencies, forming a scenario of epistemic plurality. Resumen: La pandemia de COVID-19 ha producido controversias variadas y su modo de existencia social se encuentra fuertemente ensamblado en múltiples formas de hacer mundo que movilizan particulares relaciones entre humanos-no humanos. Este trabajo analiza los modos en que la gente de los valles andinos del noroeste argentino entiende y vive la pandemia, teniendo en cuenta las formas de entender el cuerpo, la persona y el bienestar. Considera tanto el modo de vida identificado como tradicional, que implica una socialidad relacional, y el del pentecostalismo, que fomenta una corriente interpretativa bajo una clave apocalíptica. En suma, se propone pensar la convivencia y ensamblaje entre formas de vivir el padecimiento y el bienestar en el contexto de la pandemia, asociados con socialidades ampliadas y relacionales y con modos de imaginar y vivir el "fin del mundo" como manifestación específica de la tradición pentecostal. De este modo, se entiende al COVID-19 más que como un fenómeno dado y universal que produce diferentes interpretaciones o ficciones culturales, como un componente en una red amplia de agenciamientos entre humanos y no humanos, conformando un escenario de pluralidad epistémica.

Simple Summary: Anatomy is considered critical to understanding the size and shape of the different systems of animals belonging to the same group or individuals that are close in the phylogenetic scale. In the case of the Franciscana dolphin or Pontoporia blainvillei, the digestive apparatus shows some differential characteristics compared to other dolphins or other marine mammals. In the present work, the authors try to demonstrate whether these characteristics are conditioned by the animal's own diet or if they have more to do with certain phylogenetic adaptations. Considering that the Franciscana dolphin is an endangered species, any work that could facilitate better knowledge of these individuals has a high social, ecological, and scientific value because it will help in their care and conservation, and this is of utmost importance to implement effective management strategies for this species. The Franciscana (also known as the La Plata River Dolphin) is a small dolphin that lives in the coastal waters of Brazil, Uruguay, and Argentina. This species is considered the most endangered marine mammal in the western South Atlantic Ocean. Anatomic dissection of the digestive system of 19 animals of different ages, including 2 neonates, 12 juveniles, and 5 adults, was performed. Parameters related to length, breadth, weight, and diameter of the digestive viscera were considered in each case. Our results show that the Franciscana dolphin presents differential characteristics in relation to several parts of the digestive system, including, specifically, the tongue, the teeth, the stomach, and the small intestine. Thus, this paper add precious information to the actual knowledge of this vulnerable marine mammal species in order to improve conservation efforts. [ABSTRACT FROM AUTHOR]

What are the main characteristics of sectors that take advantage of the real exchange rate stimulus after a large and long-lasting devaluation? We aim to answer this question by analyzing the development of export sectors in Argentina during 2003–2008, after the crisis and large devaluation of 2002. This six-year period shows the highest number of sectors with export surge episodes from 1980 to 2015. We find, first, that the probability of export surge episodes increased 2.5% by each standard deviation of the higher labor intensity index during the large and long-lasting devaluation period because non-tradable costs prevail in their production function. Second, we show that export surges are more likely to occur in sectors related to already competitive sectors (mainly upstream sectors). Finally, the new export volumes in those sectors show persistent dynamics despite the end of the period of currency competitiveness, a signal of trade hysteresis. • This paper aims to unpack the connection between RER levels and the take-off and development of export sectors in a developing economy. • We found a positive effect of RER on the probability of export surge episodes by taking advantage of the theoretical channel through which the RER should affect export performance. • Labor-intensive sectors showed a higher probability of an export surge episode during the stable and competitive RER period (2003–2008). • We were also able to establish the relevance of productive linkages to already competitive sectors on the probability of an export surge episode during the RER stimulus. In particular, we found evidence that sectors supplying inputs to already competitive industries (upstream linkage) are more likely to achieve export surges. • We evaluated the subsequent performance of the sectors that had an export surge episode during 2003–2008 once the exchange rate stimulus ended. We find evidence of persistence in their export levels compared to the rest of the export sectors, favoring the hypothesis of sunk costs or learning by exporting effects that generate hysteresis in trade.

Weather radars with dual-polarization capabilities enable the study of various characteristics of hydrometeors, including their size, shape, and orientation. Radar polarimetric measurements, coupled with Doppler information, allow for analysis in the spectral domain. This analysis can be leveraged to reveal valuable insight into the microphysics and kinematics of hydrometeors in precipitation systems. This paper uses spectral polarimetry to investigate precipitation microphysics and kinematics in storm environments observed during the RELAMPAGO field experiment in Argentina. This study uses range height indicator (RHI) scan measurements from a C-Band polarimetric Doppler weather radar deployed during the field campaign. In this work, the impact of storm dynamics on hydrometeors is studied, including the size sorting of hydrometeors due to vertical wind shear. In addition, particle microphysical processes because of aggregation and growth of ice crystals in anvil clouds, as well as graupel formation resulting from the riming of ice crystals and dendrites are also analyzed here. The presence of different particle size distributions because of the mixing of hydrometeors in a sheared environment and resulting size sorting has been reported using spectral differential reflectivity (sZdr) slope. Spectral reflectivity (sZh) and sZdr have also been used to understand the signature of ice crystal aggregation in an anvil cloud. The regions of pristine ice crystals are identified from vertical profiles of spectral polarimetric variables in anvil cloud because of sZh < 0 dB and sZdr values around 2 dB. It is also found that the growth process of these ice crystals causes a skewed bimodal sZh spectrum due to the presence of both pristine ice crystals and dry snow. Next, graupel formation due to riming has been studied and it is found that the riming process produces sZh values of about 10 dB and corresponding sZdr values of 1 dB. This positive sZdr indicates the presence of needle/columnar secondary ice particles formed by ice multiplication processes in the riming zones. Lastly, the temporal evolution of a storm is investigated by analyzing changes in hydrometeor types with time and their influence on the spectral polarimetric variables. [ABSTRACT FROM AUTHOR]

Hydrogen, seen as a promising secondary renewable energy carrier, can becompressed or liquefied as well as chemically bound to enable a more economic storage and transportation. All conditioned hydrogen options obtain specific advantages and disadvantages. Thus, this paper assess the energy efficiency and the cost of a green hydrogen supply from well to tank exemplified for fuel cell heavy-duty vehicles in Germany related to the years 2030 and 2050. Therefore, compressed gaseous hydrogen, liquid hydrogen, liquid organic hydrogen carriers, methanol and ammonia are considered and different hydrogen production regions in North and Central Germany, as well as an import from Tunisia and Argentina (Patagonia) are assumed. The assessment shows that a hydrogen supply chain in its state of aggregation as finally demanded is the lowest cost option leading to 700 bar compressed gaseous hydrogen filling costs of 5 € 2020 /kg H2 in 2030 and 4 € 2020 /kg H2 in 2050 and liquid hydrogen filling costs around 7 € 2020 /kg H2 in 2030 and 6 € 2020 /kg H2 in 2050. • Well to tank analysis for a hydrogen supply of filling stations. • Gaseous hydrogen supply chains are the lowest cost options for gaseous filling. • Liquid hydrogen supply chains show the lowest supply costs for liquid filling. • LOHC obtain high supply costs, especially for long transportation distances.

During the 20th century, there has been an ongoing agricultural expansion and global warming, two of the main determinants influencing biodiversity changes in Argentina. The red hocicudo mouse (Oxymycterus rufus) inhabits subtropical grasslands and riparian habitats and has increased its abundance in recent years in central Argentina agroecosystems. This paper describes the long‐term temporal changes in O. rufus abundance in Exaltación de la Cruz department, Buenos Aires province, Argentina, in relation to weather fluctuations and landscape features, as well as analyzes the spatio‐temporal structure of captures of animals. We used generalized liner models, semivariograms, the Mantel test, and autocorrelation functions for the analysis of rodent data obtained from trappings conducted between 1984 and 2014. O. rufus showed an increase in abundance across the years of study, with its distribution depending on landscape features, such as habitat types and the distance to floodplains. Capture rates showed a spatio‐temporal aggregation, suggesting expansion from previously occupied sites. O. rufus was more abundant at lower minimum temperatures in summer, higher precipitation in spring and summer, and lower precipitations in winter. Weather conditions affected O. rufus abundance, but there was local variation that differed from global patterns of climate change. [ABSTRACT FROM AUTHOR]

This paper explores the implications of the conformation of formal burial areas in the southernmost limit of agricultural dispersion in South America. Previous research proposed the development of cemeteries or formal burial areas due to specialization in using specific habitats and the development of territorial ownership. From a paleoecological background, we hypothesize that hunter‐gatherers intensified resource exploitation and develop territoriality in population growth and pressure over resources. The expectation is that formal burial areas emerged in this context to legitimize the ties with the territory and ensure exclusive access to the land and its resources. To evaluate this hypothesis, we analyzed a mortuary context from southern Mendoza (Central Western Argentina), named Ojo de Agua, by describing the site's characteristics, burial modality, presence of grave goods, age at death profile, and evidence of violence. This site has two main conditions for handling our hypothesis: (1) the chronology and spatial localization coincide with the temporal and geographic dispersion of pre‐Hispanic cultigens; (2) systematic procedures during fieldwork led us to access a significant amount of information not available in other mortuary contexts of the area. Our results point to Ojo de Agua as a cemetery that emerged in the frame of increasing territoriality and conflict with neighboring groups and permitted us to improve our knowledge about the dynamic relationship between human population, environment, and cultural responses in the context of intensification and contact with food production. These results deepen recent studies in the same line but with a greater resolution. [ABSTRACT FROM AUTHOR]

The medical literature has shown that populations under high stress have a lower sex ratio at birth (i.e. number of males for every 100 females). In this paper, I examine the relationship between income, as a source of economic stress, and the sex ratio at a subnational level for the 1895–2010 period. For this, I use census microdata from Argentina -a developing country that experienced rapid growth at the end of the 19th century and stagnated in recent decades- and I estimate from a two-way fixed effects model that exploits the wide temporal and geographic variability in income. The results show that as per capita income increases, the sex ratio at birth also increases. In particular, for every US$ 1,000 increase in per capita income, the sex ratio increases between 0.3 and 0.6 points. These findings make it possible to quantify the lost boys (i.e. those boys who were not born due to high economic stress on their parents) and constitute a call for attention in favor of the implementation of prenatal care policies -especially in periods of stagnation or income decline- to maintain a more balanced sex ratio.

The purpose of this study was to develop and to, subsequently, validate a Spanish version of the Short Work-Family Enrichment Scale (sp-wfes-6). Using cross-sectional (n = 438) and multi-wave (n = 103) data from a sample of workers with different backgrounds, this paper conducted a thorough examination of the psychometric properties of the sp-wfes-6 in terms of its internal consistency, test-retest reliability, dimensionality, factor invariance, gender invariance, convergent validity, discriminant validity, and predictive validity. The results from the cfa revealed that the sp-wfes-6 comprised two factors and that this two-factor structure remained statistically invariant across gender and sample. Furthermore, both factors reported adequate levels of internal consistency, test-retest reliability, convergent validity, discriminant validity and predictive validity. Altogether, the findings of this study demonstrated that the spwfes-6 is a reliable and valid instrument to measure work-family enrichment in Argentina and, possibly, in other Spanish-speaking countries.

Objectives: The therapeutic alliance (TA) has been shown to be a predictor of psychotherapy treatment success. In the case of psychotherapy with children, there is a dearth of information on TA's role. The aims of the paper are: (1) To estimate the therapist effects on children TA; (2) to investigate if therapists' TA predicts children's TA; (3) to analyze if children's age and sex predict children's TA; (4) to evaluate if the therapist's characteristics predict children's TA. Methods: The sample consisted of 77 children undergoing psychotherapy in Argentina, and the therapists (N = 29) providing services to those children. The assessment tools utilized for the study included the Therapy Alliance Scale for Children and the Personal Style of the Therapist Questionnaire (PST‐Q). Results: Findings indicated that 2% of the children's TA was explained by the therapists (ICC = 0.02), while 17% of the therapists' TA was explained by the therapists (ICC = 0.17). Therapists' TA predicted children's TA. Children's age and sex did not have an effect on their own TA. Moreover, therapists with more experience achieved higher scores of children's TA. Finally, the Operative dimension of the PST had a negative effect on children's TA (i.e., therapists who prefer more spontaneous interventions over structured ones may experience higher levels of therapeutic alliance with child patients). Conclusion: We found a positive effect of the therapist's TA on children's TA, especially in the preference for using more spontaneous intervention techniques. We discuss the implications of the findings on the training of psychotherapists who provide services to children. [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 will develop what is understood by the right to education and how it is specifically regulated in the contexts of confinement, taking into account how the educational stimulus regulated in article 140 of Law 24.660 operates and its importance in the process of social reintegration of inmates. A comparison will be made between what is sanctioned by the National Education Law and the international human rights instruments with constitutional hierarchy that support this right and what actually happens in the penitentiary system. Likewise, an analysis will be made of Argentine jurisprudence that recognizes the right to education of persons deprived of liberty and its importance for the system of progressiveness regulated by the law of penal execution. On the other hand, an analysis will be made of how, in practice, the reduction regulated by article 140 has lost its virtuality due to the introduction of a group of offenses that are not eligible for the liberatory institutes through Law 27.375. The main objective lies in the need to emphasize that education in prison contexts is essential for social reintegration and that the State has the obligation to guarantee this right.

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.
