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 this article we study the particularities of editorial practice in contexts of confinement in Argentina through the systematization and analysis of five publications, already published or in the process of being published, which were formulated within the framework of pedagogical-political practices carried on by the Prisons Extension Program of the Philosophy and Literature Faculty of the University of Buenos Aires. These five cases will be addressed in order to observe what meanings guide the editorial processes through the marks imprinted on them by the specificity of the writing that summons them and the territory to which they belong. Publishing in the context of a pedagogical project developed by the university configures collective territories where writing and publications can display and carry plural voices, which are strengthened in that plurality forged in the heat of individual and collective subjectivation processes made possible by education and writing. Editorial practice is inseparably intertwined with actions aimed at defending rights, narrating lived experiences and building a collective history which are part of the desires and expectations regarding publication.

Objective/Context: The article seeks to analyze the problematic and paradoxical normative-administrative translation of the paradigm of human rights in Argentina's current migration policies. The study of this case is of particular interest, on the one hand, because Argentina has been and is the leading Mercosur country receiving migrations in the past decades, and, on the other hand, because its migratory management model, inaugurated in 2004 with the sanction of the Law of Migrations 25871, even if it finds itself based around the human rights approach, coexists with an emphasized tendency towards securitization and control. Methodology: The investigation that supports this article is qualitative: the main ideas and conclusions have been extracted from the study of laws, decrees, regulations, reports, and resolutions emitted by different national and international public agencies, also from the comparison and contrast with secondary bibliography. Conclusions: The advancement of the securitarian approach on migration, centered more on control than regulation, together with the lack of normative and administrative adaptation of the different state agencies in the guaranty of rights recognized as universal, explain the ineffectiveness of the human rights paradigm in critical areas such as being the documentary regularization policy and the access to universal rights. Originality: The article seeks to deepen the analysis of Argentina's migration policies, focusing on the different supra, intra, and counter-state levels involved in its implementation.

Highlights • Definition of passive envelope indexes and caracterization of libraries in La Plata. • Environmental monitoring: achievement of preventive conservation indexes. • Correlation between passive envelope indexes and preventive conservation indexes. • Determination of the most influential passive envelope indexes for the achievement of preventive conservation indexes. Abstract The common approach for libraries to preserve their paper-based collections from irreversible deterioration is by controlling quantitative parameters, such as temperature and relative humidity. Variations of these parameters for preventive conservation can be expressed by the "performance index" (PI) and the "amplitude index" (AI). Building envelope is the first filter of the external climate, buffering the external weather fluctuations and maintaining the building's indoor climate stable. Its shape, window areas and envelope materials are the most influential parameters. As they capture the relationship of a few geometric and physical variables with the building's performance, the envelope characteristics can be expressed as certain passive envelope indexes. This paper studies the relationship of certain passive envelope indexes and the preventive conservation indexes for books for several libraries and archives located in La Plata, Argentina. The results show the impact of every passive envelope index upon the preventive conservation indexes. The compactness, heaviness, adjacency to spaces and adjacency to ground have a positive linear correlation meanwhile transparency and global transmittance are parameters with a negative correlation. In general, the most influential parameter is the relative area adjacent to other spaces, followed by global transmittance, transparency, heaviness, relative area adjacent to ground and compactness.

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 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]

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.

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]

The article presents the author's perspective on how indigenous people of the Argentinean Chaco used fetishization of ID papers, which have been previously denied to them, to accept their past alienation from citizenship rights. The author examines the oddities of ID-paper fetishism in the Chaco through the concept of state fetishism. Moreover, he focuses on the historical as well as the present experiences of the Western Toba and the Wichi on ID-papers.

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]

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]

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]

In recent years, the gender agenda has permeated all policy areas and has gained relevance through the constant work of organisations that have succeeded in making issues and challenges visible. This paper examines the interaction between international politics and the gender agenda in Argentina during the presidency of Alberto Fernández (2019-2023). Based on a triangulation of information gathered from interviews, official documents, and news reports, the paper aims to analyse, in the context of recent foreign policy, what kind of decisions are linked to the gender agenda, and at the same time, what international projection the gender policies implemented at the local level have. We propose that the gender agenda has opened up a space in Argentine foreign policy in a short period and that it has done so mainly based on the country’s trajectory in the international sphere linked to human rights and the discussion of inequalities in the world. The creation of the Ministry of Women, Gender and Diversity has been crucial, projecting the country into global gender debates in an institutionalised way. Although concrete policies are developing in some cases, the agendas in this dual track demonstrate that these profound social demands have come to the state to stay. [ABSTRACT FROM AUTHOR]

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.

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.

This paper analyzes the temporal evolution of streamflow for different rivers in Argentina based on information quantifiers such as statistical complexity and permutation entropy. The main objective is to identify key details of the dynamics of the analyzed time series to differentiate the degrees of randomness and chaos. The permutation entropy is used with the probability distribution of ordinal patterns and the Jensen–Shannon divergence to calculate the disequilibrium and the statistical complexity. Daily streamflow series at different river stations were analyzed to classify the different hydrological systems. The complexity-entropy causality plane (CECP) and the representation of the Shannon entropy and Fisher information measure (FIM) show that the daily discharge series could be approximately represented with Gaussian noise, but the variances highlight the difficulty of modeling a series of natural phenomena. An analysis of stations downstream from the Yacyretá dam shows that the operation affects the randomness of the daily discharge series at hydrometric stations near the dam. When the station is further downstream, however, this effect is attenuated. Furthermore, the size of the basin plays a relevant role in modulating the process. Large catchments have smaller values for entropy, and the signal is less noisy due to integration over larger time scales. In contrast, small and mountainous basins present a rapid response that influences the behavior of daily discharge while presenting a higher entropy and lower complexity. The results obtained in the present study characterize the behavior of the daily discharge series in Argentine rivers and provide key information for hydrological modeling. [ABSTRACT FROM AUTHOR]

Migrants' home gardens may be created from elements of both old and new landscapes. We assume that medicinal plant assemblages in migrants' gardens are shaped by plant diversity and availability, therapeutic needs, and heritagization processes. Which of the factors prevail: those related to biodiversity and ecology, epidemiology, or heritage and memory? In this paper we offer new knowledge on the garden landscapes of the Global South. The research was conducted in the Atlantic Forest in Argentina. We surveyed 120 home gardens: 60 of transborder Paraguayan migrants, and 60 of transcontinental Europeans who arrived in Misiones, Argentina before WW2 and their descendants. We compared the richness, composition, medicinal uses, and the relationships of garden plants (via plant networks) between these groups, taking into account everyday scales and the transnational scale. Paraguayans cultivated and protected 137 species, predominantly native, and people of European origin 119 spp., native and exotic in similar proportions. The similarity in plant composition (68%) and the consensus in the medicinal use of plants (62%) were high between the migrant groups. Plant network analysis revealed many overlaps in assemblages of plants, but certain particularities of each group remained because of cultural expressions and therapeutic needs. This high level of similarity suggests that plant diversity, both native and allochthonous, shared concepts of illness, and the flux of knowledge between these groups was more significant than heritagization practices in shaping home gardens' medicinal plant assemblages. People of Paraguayan and European origins do not make an active effort to convert their home gardens into heritage. Medicinal plants are connected to the lived emplacement--intimate daily practices--rather than to ethnic identity strategies. Nevertheless, the plant assemblages in gardens have been shaped by ecology, colonial legacy, nostalgia, and transfer of knowledge; therefore migrants' home gardens can be considered heritage in a broad sense.

The igneous rocks of Cerro Cacheuta are considered a typical expression of the Permian-Triassic magmatism within the Andes Precordillera of Mendoza, Argentina. In particular, the southwestern margin of this hilltop is characterised by intermediate volcanic and felsic intrusives from the Choiyoi Group, one of the most extensive volcano-sedimentary suites of southern South America. The Choiyoi magmatism is widely associated with dramatic tectonic and environmental changes in the Gondwana supercontinent. Therefore, a better characterisation of the igneous facies of Cerro Cacheuta is critical to understand the evolution of Gondwana and recognise the multiple events that occurred towards the end of the Permian. This paper presents new data about the mineralogy, petrography, and geochemistry of the plutonic and volcanic units of Cerro Cacheuta, which enables authors to draw additional conclusions about the genesis and evolution of the magmatism in the region. Microscope observations indicate that the volcanic rocks are largely consistent with intermediate facies dominated by a porphyry texture with plagioclase and sanidine phenocrystals within a trachytic groundmass. Coetaneous breccias of possible hydrothermal origin and geodes with cryptocrystalline silica, limonite, and quartz are also recognised in outcrops. Geochemical analysis suggests that the lavas would likely correspond to andesites from a calc-alkaline magmatic arc. Furthermore, trace elements show enrichment in LREE/HREE, a slight negative anomaly in Eu, and concentration ratios compatible with crustal extension during the initial stages of the Choiyoi Group. Based on their chemical similarities, the monzonites of the Boca del Río Pluton would correlate with the lower section of the Choiyoi Group, of Permian age. In contrast, granites of the Cacheuta Pluton show a signature typically recognised in units from the Triassic and, therefore, would be comparable to the upper member of the Choiyoi Group.

Background and aims: The Funga of the Patagonian Nothofagus forests is being studied since the late 19th century, but despite many efforts is still far from being completely known. The aim of this paper is to present detailed descriptions and data on geographical distribution of some genera and species of mitosporic ascomycetes that constitute new records for Argentina and for the Neotropical Region. M&M: Bark and woody debris from native Nothofagaceae were collected and studied. Reproductive structures were hand-sectioned and examined following traditional mycological techniques. Results: Six species of mitosporic ascomycetes were identified: Avettaea salvadorae, Bactrodesmium atrum, Dwiroopa ramya, Gilmaniella multiporosa, Monodictys paradoxa and Pycnopeziza quisquiliaris. Full descriptions, comments on identification and data on distribution and habitat of each species are provided, along with photographs illustrating diagnostic features. Conclusions: Two genera, Dwiroopa and Pycnopeziza, and one species, M. paradoxa, are registered for the first time in the Neotropical Region, two other species are first recorded in South America (B. atrum and G. multiporosa). This constitutes the second record of A. salvadorae in the continent, thus expanding its area of distribution. [ABSTRACT FROM AUTHOR]

This paper aims to investigate how Buddhism is related to science as a mechanism for legitimizing its meditative practices and worldview. The first part takes a historical review of the different moments that mark the dialogue between Buddhism and the scientific worldview in the Western sociocultural context. Then, the paper explores the narratives of various contemporary Buddhist leaders and personalities from the scientific field to identify the different argumentative modalities that support the compatibility between Buddhism and science. From this conceptual scheme, the last section of the article analyzes the stories of committed practitioners of Buddhist centers formed in Argentina in recent decades to investigate the modalities of reception and appropriation of this discourse.

The time-dependent traveling salesman problem with time windows (TDTSPTW) is a variant of the well-known traveling salesman problem with time windows, in which travel times are not assumed to be constant. The TDTSPTW accounts for the effects of congestion at the planning level, being particularly suited for distribution problems in large cities. In this paper we develop a labeling-based algorithm for the TDTSPTW that incorporates partial dominance and generalizes several state-of-the-art components from the time-independent related literature. We propose a framework general enough to be applied to the TDTSPTW and its variant without time windows, with the objective of minimizing the duration or the makespan. As part of the framework, we introduce a new state-space relaxation specifically designed for the time-dependent context. Extensive computational experiments show the effectiveness of the overall approach and the impact of the new relaxation, outperforming several recent algorithms proposed for these variants on more than 9,000 benchmark instances. In addition, we frame the minimum tour duration problem within the time-dependent literature and include it as a benchmark for our algorithm, obtaining improved computation times and 31 new optimal solutions. Summary of Contribution: In this paper, we study the time-dependent traveling salesman problem with time windows (TDTSPTW), a difficult single-vehicle routing problem that incorporates more realistic travel time functions than its classic time-independent counterpart. As a result, the TDTSPTW is harder to solve, as it requires more complex models and algorithms. Using state-of-the-art optimization techniques, we propose an efficient solution approach for the TDTSPTW and some related variants that outperforms the previous approaches in the literature. Our paper emphasizes the importance of algorithmic design and efficient implementations to tackle relevant practical combinatorial optimization problems—in particular, for time-dependent problems. Moreover, the resulting algorithm fosters a new research direction regarding exact algorithms for time-dependent problems using dynamic programming and relaxation techniques.

Considering the increase in housing tenants (inquilinización) and financialization in Latin America, this paper explores the emergence of short-term rentals in the City of Buenos Aires, as a growing trend of housing commodification, barely incorporated into the agenda of urban studies in Latin America. To do so, we take the case of Airbnb and examined four basic dimensions to characterize the phenomenon: quantity and evolution of offers, spatial distribution, housing prices and types of owners, then comparing them with the long term rental market. Results show that short term rental shows sustained growth both over time and territory; it is a real estate market segment which is operated by concentrated and intermediary actors. Due to the low occupancy rate of the properties, the rent obtained is currently lower than in the long-term rental market. However, the post-pandemic context (still in the process of recovery) and other significant non-economic factors must be considered when interpreting these results. The paper concludes by proposing future possibilities of advance in the research of the phenomenon in Argentina. [ABSTRACT FROM AUTHOR]

In this paper, we study wage convergence and flexibility in the labour market of Argentinean provinces. We first review historical determinants and propose a theoretical interpretation: the higher the level of convergence in wages, the lower the convergence in employment and eventually in the product level, because of the low competitiveness of the Interior Area, which conspires, via a restriction of the balance of payments, against their growth. Then, we empirically analyze wage convergence and the degree of wage flexibility in provincial labour markets for the period 1997-2013. We find evidence of real wage convergence and low wage flexibility. This indicates that wages do not depend on provincial factors such as labour productivity or local unemployment but on national determinants such as centralized wage agreements.

The absence of specifications for the granulometry a quarry must produce causes a serious problem, making it difficult for quarries to adjust their processes to produce within the range required by clients, and for costumers, making it a difficult process to design asphalt mixes and concretes that conform to the granulometric curves established in regulations. It is essential to develop limit granulometric curves for quarries, adapted to customer requirements. In this paper, a methodology for granulometric control in the quarry is proposed, which includes the collection of process information, the preparation of control charts and the process capability analysis according to the established specifications. Moreover, an example of the development of limit granulometric curves is proposed for the quarry under study located in Argentina, in the province of Buenos Aires, which would allow to produce aggregates whose granulometry can be used in asphalt mixes CAC D19 and concrete pavements.

In Argentina, there is a clear consensus between neoliberals and neodevelopmentalists regarding the increase of exports as the first step towards development, consolidating the political and economic power held by the exporting business elite and, at the same time, creating an unsustainable development path in socio-environmental terms. A labyrinth with no way out. This paper has set out to retrace this labyrinth, building bridges between different currents of economic heterodoxy that enable the construction of an exit. The powerful consolidation of neodevelopmentalism at the academic and political level in Argentina shows the relevance of this discussion, which transcends national boundaries to become a global development problem due to the elements at stake.

This paper studies the mechanization of agriculture in the rural regions of the Rio de la Plata during the First Globalization (1880-1916). Uruguay and Argentina developed an important growth and diversification of their agricultural production during this period. This growth accompanied the great livestock dynamism that both economies had achieved since the first decades of the 19th century. We analyze the process by dispensing national approaches. A geo-referenced database is constructed at a micro-regional level to identify the location of the main agricultural production areas and to trace their evolution throughout the period. A clustering analysis is also carried out to explore the spatial heterogeneity that characterized the River Plate agriculture and provide elements for its interpretation. [ABSTRACT FROM AUTHOR]

The problems linked to the training trajectories of those who enter the university are not limited to social issues, personal history or the mere transition between levels, but have strong institutional conditioning factors. This paper questions the devices that national universities have designed to regulate access to the level. The objective is to present a mapping of these devices in the national universities in Argentina built from a comparative perspective. A survey of institutional regulations was carried out, as well as information available on the official website of the institutions. After the construction of a systematized data matrix, trends are identified from a cross-sectional reading of the constructed map. There is a high presence of regulatory devices for admission in national universities, with variable characteristics regarding their mode of organization, curricular components, duration and planned evaluation methodology.

Chagas disease is one of the most important public health problems in America, involving triatomines (Hemiptera: Reduviidae: Triatominae) in the vectorial transmission of Trypanosoma cruzi (Protista: Kinetoplastea: Trypanosomatidae). In Argentina, 15 species of triatomines are distributed, of which seven are the most common in the domicile and peridomicile, while the rest are mainly associated with wild environments. Due to the lack of updated data of geographic distribution, the GeoVin Project arises to provide not only a triatomine digital tool of triatomine notification, but also resources with information about Chagas and triatomine vectors. The aim of this paper is to present, describe and highlight the progress of the project, emphasizing the principles of participatory science and entomological surveillance. So far, more than 2,300 web visits have been recorded and the application has been downloaded over 3,400 times. The contribution of the project in articulating with the corresponding government health agencies and the immediacy of the interaction with the community are key elements for the project success. At the same time, the information collected is a constant input for updating the geographical distributions of Argentinian triatomines. [ABSTRACT FROM AUTHOR]

Austral Yungas cloud forest (Southern Bolivia and NW Argentina) is known for its high diversity, steep landscape and low accessibility. Anacroneuria Klapálek (Plecoptera: Perlidae) species in this ecoregion have been seldom studied. We aim to know its species diversity (based on adult characters) and explore larval characters important for their recognition. We have reared dozens of larvae from different localities and collected adults with light traps. Reared adults and associated larval exuviae were studied, photographed and drawn. We have identified 13 species (based on male aedeagus) and successfully associated larval and adult stages for seven species. In the present paper we describe seven new species: Anacroneuria tafi sp. nov., A. flavinigra sp. nov., A. saican sp. nov., A. triplex sp. nov., A. calilegua sp. nov., A. lutea sp. nov., and A. tupacamaru sp. nov. For six species previously described we present new data and stage descriptions: A. arrazayalensis Orce, A. handlirschi Klapálek, A. reedi (Navás), A. tucuman Stark, A. saltensis Froehlich, and A. chimborazo Stark. Genetic divergence for some of these species was studied using the barcode region of the mitochondrial gene COI. A key to the male adults of all the species of Anacroneuria from Northwestern Argentina is presented. [ABSTRACT FROM AUTHOR]

In this paper we seek to describe a series of short food marketing circuits with local markets in the district of Quilmes (Province of Buenos Aires, Argentina), particularly those that incorporate consumption nodes. Our aim is to identify, characterise and analyse the functioning of these experiences within the framework of the Social, Solidarity and Popular Economy. To this end, we first describe the methodology employed - which is mainly based on certain ontological, epistemological and methodological assumptions of the interpretative paradigm - as well as the spatio-temporal context of the research. Then, resorting to the notion of geographical space and network, we describe the main characteristics of these circuits involving the distribution of food of agricultural origin. Subsequently, we carry out a more detailed analysis of some of the dimensions involved in local markets organised around consumption nodes. Finally, we offer some reflections by way of conclusions.

Background: Reproductive behaviour under natural conditions is hard to record, especially in rare and cryptic species, such as the Casuhatien anole (Pristidactylus casuhatiensis). This medium size lizard is endemic to the Sierras Australes Bonaerenses, a rocky outcrop in the Southern Pampas of Argentina. Methods: During spring and summer from 2018 to 2022, we surveyed five hills at above 600 m altitude, where specimens were known to occur. Every time we detected a courtship or copulation event, we took photographs of the specimens for their individual identification, and recorded the body temperature of the participating individuals as well as air temperature, wind speed and relative humidity. We recorded the duration in minutes of each phase of the event (immobilization, juxtaposition of the cloacae followed by copulation, and finally, restraint and separation) and described the main habitat features of the site where it happened. Results: We detected 12 reproductive events; all of them occurred in October and November, on Funke, Puntudo and Tres Picos hills, mostly between 1300 and 1700 h. The mean duration of each copulation phase was 6 min (95% CI = ± 1.4, n = 10), 4.3 min (95% CI = ± 1.8, n = 10) and 3.8 min (95% CI = ± 3.42, n = 10), respectively. Conclusion: The reproductive activity of the Casuhatien anole is concentrated in the spring, particularly in the early afternoon, following the patterns described for other species of lizards. During these events, the greatest exposure of individuals could make them more vulnerable. This, together with other features related to their reproductive behaviour revealed in this paper may contribute to the planning of conservation actions. [ABSTRACT FROM AUTHOR]

This paper proposes a methodology for the estimation of the current account equilibrium exchange rate - the exchange rate that guarantees the intertemporal current account equilibrium for a country. Moreover, the methodology is tested throughout appropriate econometric technics (VECM Models) for Argentina, Brazil, Chile, and Colombia, using quarterly data from around 2000 (according to data availability for each country) to 2020. The model includes both long-term structural variables such as terms of trade, goods and service trade as percentage of GDP and GDP per capita as well short term policy variables such as interest rate differential and EMBI plus. Apart from proposing an innovative methodology for estimating the current account equilibrium exchange rate, the paper brings important insights in terms of chronicle and cyclical appreciation (depreciation) of the exchange rate in LA countries. In addition, it shows high correlation between the exchange rate negative (positive) misalignments and the current account deficits (surpluses) in the countries analyzed. [ABSTRACT FROM AUTHOR]

The paper develops a model in which the relation between the real exchange rate and the real wage, in the context of conflictive income distribution, is made explicit. It is noted that the central bank tries to regulate the distributive relation exchange rate and real wages through the changes in the interest rate. The theoretical point is that, under certain circumstances, a relatively depreciated or high level of the real exchange rate might reduce real wages and have a negative impact on economic growth. The paper also provides some evidence for the Argentine case, and suggests that the Classical Developmentalist elasticity pessimism seems, in the case of Argentina, to be validated. Also, the use of the exchange rate as an instrument to bolster redistribution away from the working class, and to promote investment and growth is also not born in the data. [ABSTRACT FROM AUTHOR]

This paper studies an adjacent accumulation discrete grey model to improve the prediction of the grey model and enhance the utilization of new data. The impact of COVID-19 on the global economy is also discussed. Two cases are discussed to prove the stability of the adjacent accumulation discrete grey model, which helped the studied model attain higher forecasting accuracy. Using the adjacent accumulation discrete grey model, non-renewable energy consumption in G20 countries from 2022 to 2026 is predicted based on their consumption data from 2011 to 2021. It is proven that the adjacent accumulation exhibits sufficient accuracy and precision. Forecasting results obtained in this paper show that energy consumption of all the non-renewable sources other than coal has an increasing trend during the forecasting period, with the USA, Russia, and China being the biggest consumers. Natural gas is the most consumed non-renewable energy source between 2022 and 2026, whereas hydroelectricity is the least consumed. The USA is the biggest consumer of Nuclear energy among the G20 countries, whereas Argentina consumed only 0.1 Exajoules of nuclear energy, placing it at the end of nuclear energy consumers.

This paper formulates a proposal for the construction of two composite indicators of social inequality intended for the comparative analysis of the social stratification between Spain and Argentina as a result of various comparative research advances carried out in different projects over the last few years. A multidimensional theoretical perspective on social stratification is adopted and an analysis model for comparative study between the two countries is implemented, which incorporates the gender dimension, which reduces coverage bias selecting the entire society and which takes into account household as an analysis unit, thus avoiding population dismemberment. We hypothesize that both countries maintain similar general patterns in terms of social stratification that structure the social inequalities of households. Although structuring patterns are common, the levels of inequality they entail are accentuated in the case of Argentina. We also understand that these levels are reproduced both when whole of society is taken into account and when only households with an employed population are considered. To account for the hypothesis, the article presents two strategies that seek to obtain two measures of social stratification as composite indicators. On the one hand, following the typological construction methodology that we call structural and articulated, where we seek to obtain a qualitative measure through a Typology of Social Stratification (TSS). On the other hand, and in the context of this methodology, we propose to generate an alternative composite indicator that measures inequalities with a quantitative variable through a Social Stratification Index (SSI). In both cases, the ultimate objective is to use these measures in the comparative study of social stratification over time and through space. In this paper, Spain and Argentina are compared with 2018 sectional data and the hypothesis is partially corroborated. [ABSTRACT FROM AUTHOR]

This study is an exploratory review about teaching practices at Argentinean public universities published between 2010 and 2019. The sample was constituted by 20 papers. The methodology was qualitative based on content analysis in three axes: work methodology, teaching practices description and characterization of the public university. The results showed a predominance of qualitative methodology, in particular of narrative approach. The aim of studies was teaching practices themselves in most of the papers, followed by directly related issues and, finally, in a few papers teaching practices were part of the aim of the study. Almost all of the papers collected data on public universities, but only a small number included the analysis of the university context in their studies. The results are discussed based on the particularities of university education in the local context. [ABSTRACT FROM AUTHOR]

The provinces of Northwest Argentina have a series of competitive advantages for the development of the cannabis industry: abundant sunshine and low rainfall, agro-industrial production specialization, an associated private sector such as textiles and pharmaceutical laboratories, among others. This paper presents the productive advances and raises a series of management and articulation challenges for the provincial management firm Agrogenética Riojana to lead the emergence of the medical cannabis industry in the NOA. The conceptual approach combines elements from the literature on the entrepreneurial state, resources and capabilities and innovation systems. Through a case study, we contribute to document and discuss the advances and challenges faced by state-owned companies of the subnational level in Argentina, which are still little explored. The experience of La Rioja is relevant in this sense, given that it is currently the most expressive in terms of the number of state-owned companies at the provincial level in Argentina.

In recent decades, at the same time that the problems of women and diversity in relation to entry and permanence in the labor market have gained visibility, gender and diversity issues have occupied a relevant place on the public agenda. In this framework, this work aims to know and analyze the gender and diversity policies implemented in national public companies in Argentina. This is an exploratory and descriptive study where regulations, documents and public information on the development and implementation of policies aimed at reducing gender inequalities in national public companies were surveyed. Specifically, this paper presents a systematization of the surveyed actions, their link with current regulations and ministerial authorities, and the presence of heterogeneity of actions carried out in the different companies.

The objective of this article is to analyze the forms that organizational hybridity assumes in subnational state-owned enterprises in Argentina --specifically, in those at the provincial level--; as well as the characteristics of the relations with the owner state and the national state, as a basis for the study of their interjurisdictional governance. The paper is based on a comparative analysis of four cases of provincial state-owned enterprise, using primary and secondary sources. Among other aspects, it is highlighted that the orientation of the companies analyzed includes a relevant presence of their public mission, although coexisting with varying degrees of commercial objectives. Likewise, the link with the owner state is mostly hierarchical, without ignoring different levels of managerial autonomy. Finally, the predominant relations with the national state are generally characterized by cooperation, usually in terms of the implementation of public policies, which reinforces the centrality of the companies' public mission.

The purpose of this paper is to analyze the economic-financial performance of public enterprises under the Sindicatura General de Empresas Públicas (SIGEP), during the Argentine democratic transition (1983-1989). For this purpose, the performance often state-owned firms is examined in four indicators: sales revenues, prices and tariffs, real fixed investment, and level of internal and external indebtedness. The statistical analysis was carried out with secondary sources, based on the balance sheets and publications of the syndicate. In conclusion, two decouplings are observed in the indicators examined, which significantly eroded the financial capacities of the companies, continuing with the dynamics installed during the last civil-military dictatorship.

This article is part of the studies on intercultural policies corresponding to the formal education system of the Argentine Republic between 1993 and 2010. As context, it considers the return of democracy, the development of new areas of social sciences, the claims of recognition and identity of the descendants of native peoples, the constant internal and external migratory movements, among other aspects. The purpose of this paper is to analyse the way in which intercultural education was/is approached by the national government -first as a program (under the Federal Education Law) and then as a modality of the educational system, incorporated by the National Education Law- and by the laws passed by the legislature of the province of Cordoba.
