In a recent collection of essays on Germany''s relations with Latin America Natalja Karthaus argued that ‘Latin America was never a priority area for German foreign policy’. Natalja Karthaus, ‘Lateinamerika als Bezugsfeld der (bundes-) deutschen Außenpolitik’, in Manfred Mols and Christoph Wagner, eds., Deutschland-Lateinamerika: Geschichte, Gegenwart und Perspektiven (Frankfurt/Main: Vervuert, 1994), 53. Karthaus''s verdict can, in fact, be extended to the Luso-Hispanic world as a whole, thus including Portugal and also, for most of the nineteenth and twentieth centuries, Spain. On aspects of the history of German – Spanish relations see now Conrad Kent, Thomas K. Wolber and Cameron M. K. Hewitt, eds., The Lion and the Eagle; Interdisciplinary Essays on German – Spanish Relations over the Centuries (New York and Oxford: Berghahn, 2000). Even Hitler''s foreign policy, despite its global aspirations, is included in Karthaus''s assessment. The focus of this article is largely on Brazil, Argentina, Spain and Portugal. These four countries were of comparatively greater importance to the Nazi regime than the other Latin American countries. On the latter see, inter alia, Jobst-H. Floto, Die Beziehungen Deutschlands zu Venezuela 1933 bis 1958 (Frankfurt/Main, Vervuert, 1991); María M. Camou, Los vaivenes de la politica exterior uruguaya ante la pugna de las potencias; las relaciones con el Tercer Reich (1933–1942) (Montevideo: Fundación de Cultura Universitaria, 1990); Klaus Volland, Das Dritte Reich und Mexiko. Studien zur Entwicklung des deutsch-mexikanischen Verhältnisses 1933–1942 unter besonderer Berücksichtigung der Ölpolitik (Frankfurt/Main, Berr: Peter Lang, 1976). To Hitler, both Latin America and the Iberian Peninsula (with the exception of Spain during the first year of that country''s civil war and again in 1940/41) were of marginal relevance to his foreign policy objectives. This verdict notwithstanding Nazi Germany maintained regular, indeed in some areas close, relations to the countries of Latin America and the Iberian peninsula which warrant closer examination.

This article combines cross-national statistical analysis and in-depth historical case studies of Argentina and Chile to explore the relationship between two crucial dimensions of state capacity. We show that information capacity contributes to the development of fiscal capacity. When states have accurate information about their subject populations, territories, and economies, they are more effective at mobilizing revenues. In developing this argument this article makes three broader contributions. First, while existing scholarship either treats distinct dimensions of state capacity as separate entities, or simply assumes that they complement each other, our findings urge scholars to treat state development as sequential and to further investigate how multiple dimensions of state capacity are interrelated. Second, the paper suggests a broader underlying set of mechanisms – economies of scope – which connect these dimensions, and explores them in the specific context of how information capacity facilitates fiscal capacity. Third, we join the scholarship on the importance of societal compliance in the creation of the fiscal state, but with a focus on elite cooperation with the state's information collection efforts, which we show to be crucial to tax state development.

An annotated checklist of the cestode parasites of Argentinean wild birds is presented, as the result of a compilation of parasitological papers published between 1900 and April 2021. This review provides data on hosts, geographical distribution, sites of infection, location of material deposited in helminthological collections, references and taxonomic comments. A host/parasite list is also provided. During this period, 38 papers were published that gather information about 34 cestode nominal species and 11 taxa identified at generic level, belonging to three orders, ten families and 35 genera. The highest number of cestode taxa was recorded in the family Hymenolepididae, with 12 nominal species and two taxa identified at generic level, followed by Dilepididae, with eight nominal species and three taxa identified at generic level. Of the 1042 species of birds reported in Argentina, only 29 (2.8%) were reported as hosts of adult cestodes. The families of birds with the highest number of reported taxa were Laridae and Anatidae, with 20 and 14 taxa, respectively. [ABSTRACT FROM AUTHOR]

This paper focuses on one orogenic belt that formed during the Rinconada phase on the final stage of the Famatinian orogeny, between 445 and 410 Ma, which is well exposed at Sierra de Ramaditas and neighbouring ranges in western Argentina. The Ramaditas Complex is formed by metasedimentary and meta-ultrabasic rocks and amphibolites. This complex forms the upper nappe of a thrust stack resulting from westward thrusting. Deformation consists of an early high-temperature S1 foliation (stromatic migmatites), coeval with thrusting and metamorphism. Metamorphism attained peak P–T conditions of 6.0–6.9 kbar and 795–810 °C, at c. 440 Ma, i.e. coincident with the Rinconada orogenic phase. The lower unit and intermediate nappes crop out in the nearby sierras of Maz and Espinal and underwent low- to medium-grade Silurian metamorphism, respectively, together with the upper nappe, defining an inverted Barrovian-type metamorphism with T decreasing and P increasing downwards across the thrust stack (i.e. westward). We argue that the Rinconada orogenic phase developed near the continental margin of SW Gondwana, during a magmatic lull following accretion of the Precordillera terrane to the continental margin at c. 470 Ma. The active margin jumped to the west after accretion, and flat-slab subduction resumed in the early Silurian, provoking thrusting and imbrication of nappe stack under the still hot root (800–900 °C) of the older Famatinian magmatic arc. This 'hot-iron' process explains both the inverted Barrovian-type metamorphism and the missing overburden of 21 to 24 km implied by the P estimate. [ABSTRACT FROM AUTHOR]

Bemisia tabaci is a complex of species, which is considered the most common and important pest of a wide range of crops belonging to many different botanical families. In Argentina, this species is recognized as a vector of geminiviruses, and Middle East-Asia Minor 1, Mediterranean, New World and New World 2 have been found to coexist in the same area. Landscape elements, like habitat patch area and isolation, define the habitat configuration and have a direct effect on insect populations between and within host patches. In this paper, we analyse the effect of potato patch configuration on the distribution and abundance of B. tabaci. Potato patches were identified using Landsat TM5 and TM7 images, and a supervised classification was performed to quantify the spatial distribution of the patches in the whole study area. Potato patch metrics were estimated using Fragstats 4.4. Generalized linear mixed models were employed to analyse the relationship between whiteflies and landscape configuration, through a multimodel inference approach, finding that B. tabaci abundance and landscape metrics were very variable. After a multimodel selection process, we found that perimeter-to-area ratio and Euclidean distance between patches were the variables that best explained whitefly abundance in potato patches. Implications of these findings are discussed. [ABSTRACT FROM AUTHOR]

This paper reports on an innovative survey of long-term care facilities for older people in the Argentine city of La Plata. It applies a range of qualitative methodologies, including a clandestine audit conducted by older people living in the community. The paper pays particular attention to the types and availability of services, perceived quality and the rigour of regulatory processes. It finds that there has been a rapid growth in the availability of formal services, but that there are many gaps in provision, especially for older people with complex care needs. There are strong indications that service quality is uneven and, in some cases, this amounts to the contravention of basic human rights. State regulation is hampered by institutional fragmentation and weak governance. A wider set of expert interviews and the limited available published information indicate that these findings are unlikely to be exceptional, and that similar issues affect rapidly emerging long-term care systems in many low- and middle-income countries.

The relationship between state and absent citizens is becoming more important since the globalization of the 1990s. Countries usually try to increase the number of their citizens through two methods. The first is by increasing the number of nationals living abroad using a dual-nationality system. The second is by expanding national power through dual culturalism. These methods increase the international capacity of the home state through the expansion of the de facto state territory from the perspective of network-power theory. Latin American countries have been relatively passive in this diaspora-engagement policy, but recently they have begun to show an active attitude by revising their migration policy—amendments to the Constitution and migration law, dual nationality, dual culturalism, voting rights abroad, and upgrading the status of diaspora agencies, etc. However, it is still unclear how the multinational and multi-ethnic Latin American countries conceptualize diaspora. This paper analyzes the diaspora-engagement policy of Latin American countries from the standpoint of network-power theory and tries to find out what its theoretical framework is. This paper concludes that the theorization work on diaspora should continue to track and analyze these policy changes, since it is difficult to understand what the diaspora concept is and what policy objectives the state is pursuing under the current diaspora-engagement policy.

This paper focuses on the intellectual path through which Raúl Prebisch placed industrialization at the center of his economic thought and policy recommendations. It shows how the changing international context of the 1930s and 1940s made him depart from laissez-faire and adopt countercyclical policies, gradually abandoning the agrarian export-led growth model and finally embracing industrialization as the new growth strategy for Argentina and Latin America.

This paper examines the tension between law's opportunity to deliver social transformation and the normative limitations that shape its effectiveness as a tool of social struggle. The role of law's normative limitations on legal mobilisation strategies, or the effect of entrenched social interests on permissible legal claims, has not been properly conceptualised in legal mobilisation scholarship. In response, this paper presents a conceptual framework that comprehends the opportunity and limitation of legal mobilisation as caught in the tension between the interpretive opportunity to redetermine legal meaning and the normative deficit inherent to this task. By re-engaging with the theoretical underpinnings of legal mobilisation, we will evaluate the potential for certain types of social transformation using law and revisit the rationale for strategic legal action. We will bring together our conceptual treatment of legal mobilisation with a sobering analysis of the Argentinian factory recuperation movement's mobilisation of legal demands. The movement's relative success in confronting the legal system's commitment to private property rights and winning protections for worker co-operatives presents an opportunity to learn about the effective potential of legal strategy and the extent to which it can be used to confront the normative commitments of a legal system.

Based on the analysis of the mobilisation processes of the middle classes in Argentina, from the events that took place in the context of the 2001 crisis, Ozarow examines how the middle class responds to collective economic and political crisis by moving beyond economic reaction in the direction of political revolt. As Kessler and I pointed out in a previous paper ('Impoverishment of the Middle Class in Argentina: The "New Poor" in Latin America', I Laboratorium i , 2 (2010)), by affecting almost all dimensions of daily life impoverishment is a constant engine of change. Daniel Ozarow takes up the challenge of analysing why non-politically active middle-class citizens engage in radical protest movements and why they eventually demobilise.

Faced with a society that demands the reduction of negative environmental impacts of agriculture while producing high-value, healthy food for local and export markets, Argentina is currently in a debate on the alternative paths toward sustainability in agricultural production. Argentina is ranked second in the world in terms of land under organic certification. Extensive sheep production in Patagonia natural grasslands accounts for most of this area and harvested organic area remains a very small fraction of total harvested land (0.6%). This paper aims to contribute to the discussion of opportunities and limitations in organic farming as an ecological intensification alternative for Argentina's Pampas. A case study was conducted on Pampa Orgánica Norte. This is a group of nine organic farmers that manages field crops and livestock-certified organic production. Farmers interviewed in this study considered different criteria including economic and environmental attributes when choosing to produce organically. However, the main drivers for conversion to organic production are related to environmental factors, in particular ecosystem protection. The main limitations in organic production are related to crop management practices, primarily weed control. To achieve the goal of increasing organic production a more active role of the public sector in technology generation and transfer was demanded by farmers. [ABSTRACT FROM AUTHOR]

This paper presents a new haploporid digenean that expands the number of species of Saccoccoelioides to 27. The new species, Saccocoelioides kirchneri n. sp. was collected from the intestine of Cnesterodon decemmaculatus (Poeciliidae: Cyprinodontiformes) from Lago del Bosque, La Plata, Argentina. The new species possesses the diagnostic features for Saccocoelioides: a sac like ceca; the vitellarium confined in two irregular groups of follicles distributed between the ventral sucker and the anterior margin of the testis; and a uterus confined largely in the hind-body, but encroaching into the range of the ventral sucker. The new species is differentiated from the 26 congeners by the body size, pharynx size, ventral sucker size, posterior extent of ceca, posterior extent of uterus and egg size. S. kirchneri n. sp. also is supported by the molecular analysis. [ABSTRACT FROM AUTHOR]

In a context of rapid technological innovation and expensive new products, the paper calls for the generation of real-world data to inform decision-making and an international discussion on the affordability of new medicines, particularly for low- and middle-income countries. Without these, the challenges of health judicialization will continue to grow. [ABSTRACT FROM AUTHOR]

The aim of this article is to review five years (2014–2018) of research in English language teaching (ELT) in Argentina. In this overview, 115 publications (conference proceedings, journal articles, and edited collections) were analysed in terms of topic and research methodologies to map out the major areas of interest and developments in ELT in Argentina. The publications are reviewed according to nine topics: (1) interculturality and citizenship, (2) language teacher education and professional development, (3) technology-enhanced language learning, (4) learner differences, (5) language skills development, (6) language systems, (7) English for academic and specific purposes, (8) assessment, and (9) language curriculum development. The review discusses trends in research practices identified in the 2014–2018 period and suggests implications and further areas of inquiry to advance research skills as well as knowledge of ELT.

ABSTRACT Since 2002, government nationalizations and contractual breaches in general around the world have surged. South America has witnessed a wave of nationalizations of private enterprises, mostly foreign. Some analysts contend that this trend is shaped by the left-wing ideological orientation of the governments, whereas others argue that a more robust explanation is the combination of economic pressure and constraint factors. This article contributes to the debate by using a nuanced institutional analytical framework based on the concept of company versus government opportunism, applied to the recent nationalization of previously privatized companies. It examines Argentina, a country that in the last two decades has seen radical policy reversals, from sweeping privatization of state-owned enterprises in the 1990s to a renationalization effort with some of the same companies in the early 2000s.

Beyond removing restrictions, trade reform in Latin American in the 1980s and 1990s was in significant part an attempt to change the domestic politics of trade and to reformulate the culture of policy management by introducing procedural characteristics that WTO trade remedy rules advance. This paper examines how trade reform in Peru and Argentina has gone since the reforms of the 1990s. Peru provides a valuable example of sustaining reforms. Leaders have used negotiations and other international instruments to disseminate among Peruvians a positive vision of Peru in the international economy, and to extend the application of WTO-based governance principles. Peru has introduced few new restrictions and all of them have been through WTO-sanctioned policy instruments. Argentina, on the other hand, has introduced multiple restrictions, through procedures that eschew WTO governance principles. Moreover, leaders there have returned trade politics to the dependencia philosophy that sees the international economy as an exploitive environment.The paper brings out the weakness of international obligations to limit Argentina's return to import substitution and the pains at which Peru has gone to maintain the management of its economy within the same rules that Argentina has so easily violated. To have commercial value, the GATT/WTO principle that members apply only approved methods of trade control must have operational expression in national institutions. [ABSTRACT FROM AUTHOR]

Courts prosecuting corruption serve a critical horizontal accountability function, but they can also play a role in moments of vertical accountability when voters can sanction corrupt candidates. This article documents the strategic use of corruption lawsuits, demonstrating the presence of an electoral cycle in filing new corruption accusations against politicians. Using an original dataset of daily corruption complaints filed in federal courts against members of Argentina's main political coalitions between 2013 and 2021, we document increased corruption accusations against and by politicians in the periods immediately preceding an election. A second dataset of daily media coverage of corruption accusations in two leading newspapers suggests that corruption is more salient before elections, offering politicians a temporal focal point to prepare and launch especially impactful lawsuits. Our findings shed new light on using courts for accountability and debates about the so-called 'lawfare' in Latin America. [ABSTRACT FROM AUTHOR]

This article explores the unpublished text of the opening lecture given by Albert Einstein for his course on the theory of relativity at the University of Buenos Aires (UBA) in Argentina in 1925. It gives a brief account of the individuals, institutions and events related to the text and compares it with the text of several lectures given by Einstein in Argentina where he briefly considered matters related to the philosophy of science. It references a short paper written by Mauricio Nirenstein in which he made some interesting remarks on the visit and the visitor.

AbstractThe effect of flooding on the dormancy level of Setaria parvifloraseeds from a non-flooded upland and a seasonally (winter?spring) flooded lowland in the Pampa grasslands of Argentina was investigated. Seeds from both communities were subjected to reciprocal burial treatments in the two habitats, and exhumed during and after the flooding season. Effect of immersion in water at 5?C was compared to incubation of seeds on the surface of water-saturated paper at the same temperature. After exhumation of the buried seeds or immersion treatments, germination was assayed at 25?C and at 20/30?C in the dark or in combination with light. Burial in the lowland, which was flooded in winter?spring, significantly reduced germination, while burial in the non-flooded upland did not reduce germination. Similarly, immersion in water at 5?C significantly reduced germination compared to non-immersed controls. During summer, seeds buried in the lowland showed increased capacity to germinate, particularly when exposed to fluctuating temperatures or light. Thus, flooding induced secondary dormancy in S. parvifloraseeds, and it was broken during the non-flooding season. These responses of the seeds would prevent germination until there was no further risk of flooding. Remarkably, in S. parvifloraseeds harvested from both habitats, we observed essentially the same germination requirements after flooding. However, some slight differences were detected between the seed populations exhumed from the lowland site, indicating that flooding had larger effects on the seeds from the upland community. This suggests some differentiation of these populations evident only after flooding in the field. [ABSTRACT FROM AUTHOR]

Based on archival research and on multi-sited fieldwork, this article offers the first available description of the food lootings that took place in Argentina in December 2001. The paper joins the current relational turn in the study of collective violence. It examines the existing continuities between everyday life, routine politics and extraordinary massive actions, and scrutinises the grey zone where the deeds and networks of looters, political entrepreneurs and law enforcement officials meet and mesh. The article reconstructs the looting dynamics at one specific site and highlights the existence of three mechanisms during the episodes: 1. the creation of opportunities by party brokers and police agents, 2. the validation of looting by state elites, and 3, the signalling spiral carried out by party brokers.

This paper analyses testimonies of survivors of the detention camps operated by the last military dictatorship in Argentina, with special attention to the functions served by the referencing of testimonies of the Shoah (above all in Ese infierno, a collective testimony by five women in dialogue form). The intertextuality herein assumes different functions in the shaping of discourses and representations, whether in the form of a quotation, an epigraph, a metaphor, an endeavour to legitimise what is being said, a comparison, or an effort to incorporate one’s own experience into a narrative of the catastrophe already so well known in human history.

This paper presents new descriptions of Anacardiaceae fossil woods from the Ituzaingó Formation (late Cenozoic) at the Toma Vieja, Curtiembre, and Arroyo El Espinillo localities, Argentina. We describe eight silicified woods assigned to four different species in three genera, one of which, Parametopioxylon crystalliferum n. gen. n. sp., is new. Similarities between these three genera and the six Anacardiaceae species previously recorded from the late Cenozoic in northeastern Argentina are investigated using multivariate analysis techniques (correspondence and cluster analysis). Our study is based on 33 characters scored for 17 fossil specimens (10 Astroniumxylon Brea, Aceñolaza, and Zucol 2001; five Schinopsixylon Lutz, 1979; and two Parametopioxylon n. gen.) and four extant species (Astronium balansae Engl., Astronium urundeuva Engl., Schinopsis balansae Engl., and Metopium sp.). Our main goal is to determine the wood anatomical features useful for distinguishing among these species. Results of the multivariate analyses support the previous classification where Schinopsixylon is distinguished from Astroniumxylon by having exclusively paratracheal axial parenchyma, ≥30% multiseriate rays, and multiseriate rays that are ≥5 cells wide and commonly 301–400 μm in height. Additionally, we propose that Schinopsixylon heckii Lutz, 1979 is synonymous with S. herbstii Lutz, 1979. A diagnostic key for the fossil species studied is given. Wood anatomy of Anacardiaceae fossil woods from Argentina (late Cenozoic) suggests a warm, dry to semi-humid climate for this region, supporting previous studies. [ABSTRACT FROM AUTHOR]

Objective: To assess the association between the consumption of ultra-processed foods (UPF) and diet quality among preschool children and women of reproductive age from Argentina. Design: Cross-sectional and nationally representative survey. The food items were classified according to the NOVA system. Consumption of fruits, vegetables, legumes, nuts, seeds and wholegrains was estimated, and the energy and nutrients related to non-communicable disease (NCD) intake. Linear regression was used to assess the associations. Setting: Argentina. Participants: Children aged 2–5 years (n 7022), female adolescent aged 10–19 years (n 2165) and women aged 20–49 years (n 4414). Results: UPF represented more than a quarter of total energy intake, 27 % in children, 31 % in female adolescents and 26 % in women. Across all age groups, the major contributors to UPF consumption were cookies and pastries (about 6·0–7·0 %), soft drinks (about 2·7–3·7 %), candies (about 1·8–4·6 %), and juices (about 1·3–1·7 %). The consumption of fresh vegetables, fresh fruits and legumes was negatively associated with UPF consumption. A significant positive association was found between the dietary share of UPF and the dietary content of NCD-promoting nutrients such as free sugars and total saturated and trans -fats. In contrast, a significant negative association was found with the content of NCD-protective such as fibre and protein. Conclusions: UPF were associated with lower consumption of healthy foods and higher intake of nutrients related to NCD in children and women of reproductive age in Argentina. It is necessary to design food policies that simultaneously reduce the consumption of UPF while promoting the intake of fresh and whole foods to improve the dietary quality. [ABSTRACT FROM AUTHOR]

This paper describes the helminth community of the Pampean grassland mouse (Akodon azarae) inhabiting poultry farms in central Argentina. Winter diversity (season of high rodent abundance) has been compared to spring diversity (season of low rodent abundance). Species richness was seven in both seasons: five nematodes (Syphacia carlitosi, Stilestrongylus spp., Trichuris laevitestis, Pterygodermatites (Paucipectines) azarai and Protospirura numidica criceticola) and two cestodes (adults of Cyclophyllidea and Taenia taeniaeformis hepatic cysts). No difference in richness was detected between host sexes in each season or among host age classes. However, the helminth community showed 67% similarity between winter and spring, with diversity being significantly higher in spring (H = 0.873) than in winter (H = 0.546; P < 0.0005). This could be attributed to different factors, such as host abundance, host diet or environmental factors, that affect the transmission of each species differently. On the other hand, Stilestrongylus spp. and S. carlitosi showed higher dominance and intensity in both seasons compared to their cohabiting species, P. (P.) azarai and T. laevitestis, respectively. The lower values of the latter two species may be related to a crowding effect due to their large body sizes. This is the first report of cestodes in A. azarae. The finding of T. taeniaeformis strobilocerci could be important in the epidemiology of parasitosis in domestic animals of the farms. [ABSTRACT FROM PUBLISHER]

This paper examines relations between the state and capital in Argentina with respect to agricultural biotechnology. Argentina is one of the world's leading exporters of genetically modified (GM) crops and is a key player in the global politics of biotechnology. Whereas in other parts of the world, including other countries in Latin America, active civil societies and some governments have rejected the technology, Argentina has adopted it as a central accumulation strategy. The desirability of this strategy has been secured in material, institutional and discursive arenas of power, producing a particular expression of 'bio-hegemony'. Looking at the role of business in the political economy of agricultural biotechnology is revealing both of the extent and forms of corporate power and contributes to an understanding of hegemony in practice.

This paper links the theory of interest groups influence over the legislature with that of congressional control over the judiciary. The resulting framework reconciles the theoretical literature of lobbying with the negative available evidence on the impact of lobbying over legislative outcomes, and sheds light to the determinants of lobbying in separation-of-powers systems. We provide conditions for judicial decisions to be sensitive to legislative lobbying, and find that lobbying falls the more divided the legislature is on the relevant issues. We apply this framework to analyze supreme court labor decisions in Argentina, and find results consistent with the predictions of the theory. [ABSTRACT FROM AUTHOR]

This paper analyzes the conditions in which the governments of Argentina and Brazil founded security institutions in the early 1990s, while they were democratizing. It advances the hypothesis that international cooperation in the security field is often linked to the evolution of civil-military relations. Civilian leaders in both countries established institutions and sought international participation deliberately to achieve civilian control and gain leverage over the military establishment, which they sorely distrusted. The need to stabilize civil-military relations at home was therefore the prime motivating force behind the emergence of security institutions in the Southern Cone. Three mechanisms were at work: omnibalancing, policy handling, and managing uncertainty. These mechanisms are derived from three different schools of thought: realism, organizational-bureaucratic models, and theories of domestic political institutions. Besides explaining the sources of nuclear bilateral cooperation, this argument also serves as a critique of two prominent theories in international relations that attempt to explain cooperation and peaceful relations among democracies: neoliberal institutionalism and democratic peace theory.

This paper addresses the dispute brought to the World Trade Organization (WTO) by Argentina concerning certain Chilean measures affecting the importation of wheat, wheat flour, oil seeds, edible vegetable oils and sugar. The complaint by Argentina challenged two types of policies – a ‘price band system’ that was applicable to four of those product categories, and safeguard measures that were applicable to three of them. The WTO panel ruled in favor of Argentina on both sets of measures. It found that the price band system violated Article IV of the Agriculture Agreement and Article II of GATT 1994. The safeguard measures, according to the panel, violated various provisions of the Safeguards Agreement, as well as Article XIX of GATT 1994. Chile elected not to appeal the panel ruling regarding the safeguard measures, but did appeal the adverse finding as to the price band system. The Appellate Body subsequently affirmed in substantial part the finding that the price band system violated Article 4 of the Agriculture Agreement, but reversed the finding of a violation under Article II of GATT 1994. Chile has since indicated an intention to comply with the ruling, and an arbitration pursuant to Article 21.3 of the DSU determined that the reasonable period of time for compliance would expire on December 23, 2003.

Light and temperature conditions trigger germination in specific temporal windows and microhabitats, thus determining the germination niche of plant species. Manihot species grow in fire-prone ecosystems and their seeds show heat tolerance. Successful establishment in disturbed environments might be related to seed attributes that allow seeds to cope with or avoid stressful environments. We studied some characteristics of the germination niche of Manihot grahamii , a pioneer woody species present in dry subtropical forests of central Argentina, to understand its successful establishment in disturbed environments. We evaluated the germination ecology of the seeds of M. grahamii with the aims to (1) characterize seed traits (viability, mass and moisture content); (2) determine whether it has dormancy and if it is physical or physiological; (3) evaluate the effect of several pre-treatments (gibberellic acid, after ripening, dry prechilling and dry prechilling + warm) on seed dormancy; and (4) assess the effect of different environmental events of high temperatures on the germination process simulating two treatments: fire intensities (with three levels of heat shock) and a gap temperature. M. grahamii seeds have large mass (0.24 g), low moisture content (8%), physiological dormancy, negative photoblastic behaviour and high heat tolerance. Dormancy was alleviated and seeds became insensitive to light when they were exposed to pre-treatments of dry prechilling + warm and high-temperature treatments. This germination strategy promotes secure germination timing into the rainy season on undisturbed habitats as well as a cue for competition-released gaps which in turn favour recruitment in open, disturbed and dry habitats, respectively. In the context of global change, with an increasing habitat fragmentation and fire frequency, M. grahamii could become more abundant and extend its geographic distributional range in central Argentina.

Firms should be considered as actors that potentially mediate between social movement pressures and policy outcomes. This article shows that at the mining project level, social mobilization can generate important changes in corporate practices toward nearby communities, and that these practices can undermine the cohesion of social movement coalitions advocating for regulatory intervention or reform, thus limiting their ability to make compelling claims on the state. In this way, company interpretations of and responses to protest are an important mediating process that conditions civil society efforts to activate state institutions in their favor. This argument extends recent work on the social foundations of regulation in Latin America by including corporate actors. The article is based on a comparative case study of the Pascua Lama/Veladero mining projects in both Argentina and Chile, using both secondary sources and primary field research.

Sponges, especially Calcarea, are minor components of benthic associations, especially during the Mesozoic. In the Lower Cretaceous of the Neuquén Basin, small calcareous sponges have been found building a small monospecific meadow. It is restricted to a marlstone lens-shaped bed in a quiet outer-ramp setting in the Cerro Marucho Locality (Picún Leufú depocentre), above a shell bed of small exogyrid oysters; oysters and sponges were the only preserved macrobenthic faunal elements. Individual sponges were small, under 4 cm high, and presented a sub-cylindrical morphology with one or more rounded, apical osculi, many inhalant openings and triactine spicules. Specimens studied here were assigned to Endostoma sp. aff. Endostoma nodosa. These sponges are quite commonly encrusted by exogyrid oysters, serpulids, sabellids, agglutinating foraminifers and cyclostome bryozoans. Overgrowths among sclerobionts were common, though no undoubtedly in vivo interaction has been recorded. Disarticulated left oyster valves were frequently bioclaustrated by the sponges, showing that in vivo settlement upon sponges was common. Many oysters settled in the periphery of the osculum suggesting a commensal relationship. The study of this sponge meadow and its sclerobiont community allowed the identification of different stages of ecological succession. The pioneer stage was characterised by sponge settlement on oyster valves, within an otherwise soft consistency bottom. High sedimentation or high nutrient inputs, either individually or in combination, could explain the great abundance of oysters. During the climax stage, sponges thrived and harboured several sclerobiont taxa, developing a relatively dynamic palaeocommunity. Finally, an intensification in either sedimentation rates or nutrient input (or both) past the tolerable threshold for sponges may have been the cause(s) of the meadow's demise. Endostoma and similar forms were up to now reported mostly from the Jurassic and Cretaceous of Europe as accessory builders, or as accompanying fauna in reefal settings. This new record shows that in rare occasions they could form low-relief meadows on their own. [ABSTRACT FROM AUTHOR]

In this paper, we assess the impact of the introduction of cultigens on human organization and the resultant degree of dependence on food production and domesticated plants in central western Argentina. The study compares three sites with human skeletal remains (Jaime Prats-1, Rincón del Atuel-1, Cañada Seca-1) separated by a maximum distance of 40 km and located in the southernmost region of Andean prehispanic agriculture. The sites have regional temporal occupation continuity dating back to 1900 (300 years after introduction of domesticated plants) to 1400 years BP. Data from stable isotopes (13C, 15N, 18O), and cranial, mandibular, and dental morphometry are compared, along with archaeological information. Jaime Prats-1 and Cañada Seca-1 exhibit isotopic and morphologic similarities, despite not being chronologically contemporaneous. At the same time, these two sites have differences with Rincón del Atuel-1, temporally placed among them. Our results point to a greater importance of maize (although its dietary contribution is less than 30%) and lower residential mobility in Rincón del Atuel-1. Human systems that occupied the agricultural frontier during the first 500 years since the introduction of domesticated plants show high variability in their organizations, with agriculture playing a minor role in sustenance.

Intense aeolian processes in arid and semi-arid environments play an essential role in the preservation and destruction of archeological sites. This is especially the case in the lower basin of the Colorado River at the eastern Pampa-Patagonia Transition of Argentina, as is illustrated by geoarchaeological and chronostratigraphic studies at a mid-Holocene hunter-gatherer site, La Modesta, where aeolian processes strongly influence the archeological record in dune sediments. At La Modesta, surface archaeological materials are numerous and well preserved, although the stratigraphic record is incomplete. Optically stimulated luminescence (OSL) dating of sediments that contain cultural material provides a chronology dating from ca. 8.2 ka but shows one or more hiatuses from ca. 6–2 ka in the sedimentary succession. Intense morphogenesis related to arid climates likely caused gaps in sedimentation, affecting the integrity and resolution of the archaeological record. This study helps explain mid-Holocene archaeological discontinuities throughout central Argentina and highlights the importance of considering taphonomic and geologic biases when dealing with the absence or reduction of the archaeological record in dryland regions.

This article investigates the drivers of trade union choices in the social policy arena in the age of austerity. Against the background of a political economy literature mostly emphasising trade union support for their stronger constituency – i.e. the 'insiders' – the article shows the existence of mechanisms potentially inducing trade unions to broaden their demands. Empirically, the study rests on an in-depth comparative analysis of the political process inducing the two largest trade unions in Argentina and Italy, the CGT and the CGIL, to support 'pro-outsider' social policy actively. Besides the comparison of two different geographical areas – though not so different in terms of original welfare state configuration – the main contribution of this article is outlining how the combination of dwindling organizational resources and growing competition from social movements and/or new radical unions leads traditionally insider-oriented unions to reach out to new constituencies and advocate expanded redistributive demands.
