During a dengue-3 outbreak in Paraguay at the beginning of 2007, capillary blood samples absorbed onto filter papers were collected from 44 suspected cases. These samples were subjected to three molecular and serologic tests, and 31 of the 44 samples gave a positive result by at least one of the techniques used. Molecular analyses detected the dengue-3 serotype in 22 patients and additionally the dengue-2 serotype in two patients. Therefore two different serotypes were co-circulating during this outbreak. Overall, this study validates the use of dried-blood samples for field screening investigations. Indeed, all types of laboratory studies of dengue were possible with samples consisting of a few drops of dried blood from finger pricks.

As mosquito-borne diseases like dengue and Zika continue to develop, traditional approaches have not curbed the epidemics, and evidence suggests that community-based programs are an effective alternative. In Paraguay, more than 8,300 cases of dengue were reported in 2019. Recent entomological surveys found that the percentage of houses with Aedes aegypti larvae is as high as 20% in the capital. In this context and based on the experiences of Camino Verde and DengueChat in Nicaragua, we started the TopaDengue project, a community-based intervention, supported by ICTs (information and communication technologies), in one of the most vulnerable territories of the Paraguayan capital, the Bañado Sur of Asunción. To inform our design of the socio-technical ICT platform, our fieldwork in this community explored the dynamic of interaction among researchers, facilitators, volunteers, the extended community, and technologies. Combining both paper and digital technologies with a continuous feedback loop among research, design, and community action, within a citizen science initiative, were key to strengthening the socialization and management processes of a community-based entomological surveillance program.

A structural analysis of Cretaceous alkaline dykes swarm associated with the central segment of the Asunción Rift is reported here. Dykes are generally single near-vertical tabular bodies, less than 5m wide, although multiple and composite intrusions also occur. Many of these small bodies have been emplaced into Paleozoic sedimentary rocks and exhibit a regional NW-SE orientation pattern. Petrographical and geochemical data allow recognition of two different lineages of potassic dykes: a silicaundersaturated suite ranging from basanite to phonolite (B-P) and a silica-saturated suite ranging from alkali basalt to trachyte (AB-T). The morphological features, the regional en-échelon distribution, and the NW-SE orientation pattern suggest that the dykes were injected along fractures and faults, under a transtensional tectonic regime with σ1 NW/horizontal, σ2/vertical, and σ3 NE/horizontal.Detailed analysis, combining dyke petrography, orientation pattern, and relative chronology reveals a rotation from WNWtoward NNW during dyke emplacement. In terms of the paleostress field orientation, the evidence indicates that the dykes were diachronically formed under a similar stress condition. Finally, the pattern of orientation documented for the Cretaceous alkaline dykes of the Asunción Rift is consistent, temporally and spatially, with the phases of regional deformation that occurred during the process of the Atlantic Ocean opening.

Rural poverty in Paraguay led to the implementation of the 'Sembrando Oportunidades Familia por Familia' program (SOF), an initiative based on the graduation approach and one of the few government-run implementations of this kind of program. We evaluate the intervention outcomes in poverty. There are positive changes in the participants' income, productive capacity, savings behavior, and perception of well-being, but discrete consumption effects. These might suggest the need to complement the intervention in rural communities with other targeted interventions. The paper informs the scaling of graduation programs, so they help overcome extreme poverty in this and other developing countries. [ABSTRACT FROM AUTHOR]

Protected areas are a fundamental element for the protection of ecological integrity and, in some cases, the livelihood of local communities worldwide. They are also embedded in socio-ecological systems, and their management is subject to various political, economic, and social influences. Good governance of protected areas is recognized as a decisive aspect of ecological conservation, which is at risk in institutional contexts where there is a weak scope of action alongside issues with misrecognition of key actors and their representation in procedures. In this context, the present study case aims to assess the performance of the Río Negro National Park governance system in terms of effectiveness and justice to enable the identification of strategies to improve this protected area governance system for the achievement of its desired outcomes. Using the social-ecological systems approach, this paper proposes an analytical framework for the performance assessment, including both the effectiveness and justice of the governance of socio-ecological systems, stemming from the socio-ecological justice framework. It uses mixed methods based on semi-structured in-depth interviews supplemented by a focus group discussion, participant observation, and secondary data analysis. Results show that the governance of Río Negro National Park is negatively impacted by low-capacity, a lack of human, financial, and technical resources, as well as the lack of recognition of the indigenous community of the Yshiro and the rural community as key actors, leading to a lack of representation of their interests, values, and knowledge in norm-making and decision-making processes. The findings unveil some windows for improvement through better-designed environmental policies specifically based on collective action and social learning. The results demonstrate that effectiveness and justice influence each other and, therefore, are deeply intertwined. From the assessment conducted, the paper highlights the components of the governance system that should be improved to achieve good governance of the protected area as a socio-ecological system, promoting the ecological integrity and the dignity of life (socio-ecological justice) of the individuals and communities that are part of this system.

This paper examines the global soybean market in a holistic way, analyses the land use and other historical determinants of soybean exports, such as labour and capital endowments, soybean productivity, international prices and demand conditions through an empirical model. In addition, it pays particular attention to the role of leading exporters in the export changes and the nature of the connections between them in an interrelated system. The results suggest that the productivity per hectare and the land used to harvest soybeans are the main factors explaining soybean exports in a global context. The analysis also reveals that Brazil, the current market leader, positively influences the other exporters. On the contrary, minor exporters such as Ukraine, Paraguay, or Canada present competitive relationships with the major exporters. The nature of the relationships between the exporters and the pressure on natural resources highlight the importance of government involvement in developing joint strategies that ensure the growth of this sector and the achievement of United Nations Sustainable Development Goals.

This paper discusses the emergence of a hortative marker in Guaraché, a new mixed language in Paraguay, the result of language mixing of the Indigenous Aché language and Paraguayan Guaraní. After settlement on reservations, the formerly nomadic Aché hunter-gatherers began shifting to the national language Guaraní, resulting in Guaraché, which is currently learned by children as their first language. Guaraché speakers have incorporated parts of the lexicon and morphology from Aché and Guaraní into their verbal repertoires, including parts of the Guaraní inflectional morphology. Thereby, they are modeling their use of the Guaraní 1pl.in marker ja-/ña- on a specific function that it has in Guaraní, hortative mood. Neither Aché nor Guaraní have grammatical hortative markers. Such a reanalysis and transfer of only one function of ja-/ña- suggests that a novel grammatical distinction is emerging between ja-/ña- for the hortative and the free pronoun ñande/nande for all other cases of 1pl.in. This paper analyzes hortative constructions in a corpus of recordings of naturally occurring interactions from children and adults. This case of grammaticalization is a strong indicator of a gradual transformation of Guaraché from language-mixing practices into a new mixed language. [ABSTRACT FROM AUTHOR]

Critical scholarship about datafication reveals the implications of algorithmically driven digital transformations for both social processes and human experiences of subjectivity. Digital transformations embed ontological beliefs in the information systems that drive new organizational processes and are accompanied by techno-positivist discourses that promote the benefits of these schemes. The dual power of new information systems plus strong discursive influences has led to fears that data subjects will come to be defined by data and information systems – that their subjectivity will be subordinated by the algorithm. However, in this paper, we argue that real experiences of data sharing offer a means to reveal actual experiences with subjectification, and that often these experiences are multiple and complex. Drawing on the results of five digital literacy interventions carried out by partner organizations in Chile, Colombia, Paraguay, Peru, and Uruguay in 2021, we consider participants' lived experiences with datafication. Our work reveals how people experience, negotiate, reject, and accept data power's multiple manifestations in ways that strategically mobilize data resources, constituting a fractured data subjectivity that overlaps the bounds of any one information system. This leads us to suggest the idea of the 'unhomed' as a useful concept for understanding data subjectification in the contemporary moment. [ABSTRACT FROM AUTHOR]

This paper seeks to further conceptualise participation in International Large-Scale Assessment (ILSA) as a global ritual of belonging and apply it to understand the appeal of PISA for Development (PISA-D) in Ecuador and Paraguay. The paper develops the theoretical underpinnings of the global ritual of belonging through policy borrowing and lending theory. The paper draws on ethnographic observations and interviews carried out with high level policy actors in Ecuador and Paraguay during their first implementation of an OECD education programme to understand how global policy tools resonate locally. Beyond demonstrating global accountability, mobilizing resources, acquiring technical capacity, attracting investors, and accessing the transnational accreditation PISA provides educational systems, it emerges that PISA-D is valued for the global stage it provides and the relationship it entails with the OECD. In the era of ILSAs, having a relationship with the OECD and appearing on the OECD maps provides governments with a form of legitimization and denotes states as modern and responsible.

This paper offers a new framework to understand institutional change in human societies. An 'institutional fork' occurs when a society splits into two divergent paths with shared histories. The idea of forking comes from the open-source software community where developers are free to copy of a piece of software, alter it, and release a new version of that software. The parallel between institutional choice and software forking is made clear by the function and politics of forking in blockchain implementations. Blockchains are institutional technologies for the creation of digital economies. When blockchains fork they create two divergent communities with shared transaction ledgers (histories). The paper examines two instances of institutional forks. Australia can be seen as a successful fork of eighteenth-century Britain. The New Australia settlement in Paraguay can be seen as an unsuccessful fork of nineteenth century Australia. [ABSTRACT FROM AUTHOR]

Knowledge on seed ecology is foundational for effective seed‐based restoration including seedling production, direct seed sowing, topsoil transplant, and natural regeneration. Consequently, quantifying available knowledge and biases in seed‐based research allows practitioners to better plan and implement seed‐based restoration programs and identify research priorities. Using a systematic review comprising 45 papers, 401 species, and 2,415 case studies, we provide an overview of seed ecology research in the Pantanal, the world's largest tropical wetland. We identified geographic, taxonomic, and ecological biases, as well as knowledge gaps in seed functions including production, dispersal, dormancy, germination, predation, and stress tolerance. Studies concentrated near large cities resulting in extensive unexplored sites in central Pantanal, in Paraguay, and in Bolivia. Unexpectedly, the most studied species were conducted with dry‐fruited, terrestrial forbs, or shrubs with autochoric or zoochoric dispersal syndromes. Seed banks, stress tolerance, and dispersal were the most studied topics, whereas studies on dormancy and seedling establishment remain rare. We also found disproportionate research interest across the angiosperm tree of life with many examples of underrepresented and overrepresented families. Altogether, persistent knowledge gaps in seed‐based research in the Pantanal hinder upscaling restoration programs and consequently the likelihood of achieving the targets of UN Decade of Ecosystem Restoration. We propose an integrated agenda consisting of a series of orchestrated actions to overcome such barriers, close biodiversity knowledge shortfalls, and promote successful large‐scale restoration programs in the Pantanal.

The Paraguay River Waterway is a crucial axis for integration in South America, with a course of 3.442 km from Cáceres (Brazil) to Nueva Palmira (Uruguay). To provide the navigation, improve the safety, the reliability and efficiency of the waterway transport, for a minimum period corresponding to 90% of the year, interventions with amelioration works are necessary. Among them, dredging in critical stretches stand out, which currently present some form of obstacle to navigation, either by natural factors (widths, radius of curvature and depths) or by structures, such as bridges, and sand shoals. This paper proposes a reassessment of the current nautical dimensions based on new guidelines, assessing critical sections for depth, width, and radius of curvature. The aim is to increase safety and study the feasibility of expanding the waterway by accommodating larger convoys. [ABSTRACT FROM AUTHOR]

This paper analyses the effects that the Itaipú Hydropower Plant has had in the development of capabilities and the evolution of energy security aspects in Paraguay and Brazil. To do this, it applies a theoretical framework that integrates elements from the energy security literature with the concept of capabilities. Applying the framework sheds light on the evolution of the financial, organisational, and technical capabilities that developed in connection with the building and operation of the dam and its impact on energy security in both countries. The research design of the study is an in-depth case study drawing on qualitative data including original interviews collected between 2020 and 2021 as well as on an extensive review of official documents and statistical data. The paper finds that the dam had a deep and lasting impact in the evolution of the electricity sector in both Paraguay and Brazil with positive as well as negative impacts in energy security across all the analysed dimensions. The paper presents relevant case specific conclusions as well as general implications of the findings that emerge and can potentially inform similar situations in other settings where large electricity endowments are shared by two or more countries, irrespective of the technology. • Integrates elements of energy security and technical, organisational, and financial capabilities • Presents original research on the impacts of the Itaipú hydropower plant • Contrasts impacts of transboundary hydropower in Paraguay and Brazil • Draws on original qualitative and quantitative data collected in three countries [ABSTRACT FROM AUTHOR]

The new direction on the link between a measure of exchange rate volatility on trade flows is to estimate nonlinear models to determine if trade flows respond to exchange rate volatility in an asymmetric manner. In this paper we consider the U.S. trade flows with 12 South American partners. Estimates of traditional trade models revealed that only U.S. exports to Paraguay and Venezuela and its imports from Peru responds adversely to exchange rate volatility in the long run. However, estimates of nonlinear models predicted that U.S. exports to Bolivia, Chile, Colombia, Paraguay, and Venezuela, and its imports from Argentina, Bolivia, Peru, Suriname, Uruguay, and Venezuela are affected asymmetrically. Clearly, the nonlinear approach yields relatively more significant outcomes than the linear approach and must be the norm for future research on the topic. [ABSTRACT FROM AUTHOR]

Prenatal exposure to pesticides of different chemical groups is associated with an increased risk of anthropometric, neurological, and neurodevelopmental alterations in children. The paper reports an evaluation of the neurodevelopmental, nutritional, and sensory status of a group of children belonging to birth cohorts with and without prenatal environmental exposure to pesticides, in the department of Alto Paraná, from a previously published study. A prospective observational study was conducted. The neurodevelopmental status was evaluated with the Battelle Developmental Inventory Screening test (BDIST). The sensory status was assessed through an ophthalmological examination and an otoacoustic emissions test. A total of 100 children aged 34 to 36 months, of whom only 50 were exposed to pesticides during the prenatal period, were included in the study. Results showed that 45% of the children studied had neurodevelopmental impairments. The cognitive area was the most affected (56%) and the risk of abnormal neurodevelopment was 5.6 times higher in children who had been prenatally exposed to pesticides than in the unexposed. Malnourished children were 4 times more likely to have an abnormal BDIST result. Results suggest that prenatal pesticide exposure is an important risk factor for lower neurodevelopment in children at 34 to 36 months of age, adjusted for socioeconomic factors.

This paper documents aftermaths of Indigenous collective land titling in Northern Paraguay, drawing on participant observation, interviews, and archives involving Indigenous Guarani, private landholders, NGO partners, and campesinos. While collective title attempts to safeguard Indigenous land, I argue that land available for Paĩ Tavyterã Guarani livelihoods was reduced, with sometimes violent sociopolitical impacts and challenges to land control. I contend that the unfinished, hegemonic process of land titling is contested through Guarani communities' sociopolitical creativity, where the Paĩ creatively adapt their ways of life on land reduced. This contributes to debates on territorialization, land titling and rights, and political economy. [ABSTRACT FROM AUTHOR]

For International Valuation Standards (IVS) the estimate of the "forced sale" value implies a value judgment with reference to a degeneration of the market value basis, since "a forced sale" is a description of the situation in which the exchange takes place, not a distinct basis of value (IVS 2022, Par. 170.1). The paper illustrates a model that can be used to measure the difference between market value and forced sale value, as an aid to real estate valuations related to real estate executions. The proposed method is aimed at determining the difference between the estimated values and the final sales values obtained through the executive process, on the basis of the Short Table Market Comparison Approach (MCA). This method contributes more appropriately to the estimate of the value obtainable from the outcome of the enforcement process than arbitrary reductions in the market value. An application on a small sample of residential properties undergoing enforcement procedure highlights the possibility of using the Short Table MCA even with a limited number of comparables.

Human immunodeficiency virus (HIV) drug resistance increases mortality and morbidity and antiretroviral therapy (ART) costs. We describe Paraguay's first nationally representative survey on pretreatment drug resistance (PDR) conducted among persons who initiated or reinitiated ART in 2019. ​​​​We conducted a cross‐sectional survey of antiretroviral (ARV) drug resistance in Paraguay in 2019. Participants were sampled at four comprehensive care clinics where 90% of patients with HIV in Paraguay initiate ART. Patients included were adults ≥18 years old who initiated first‐line ART or reinitiated the same first‐line ART regimen after ≥3 months of discontinuation. Of 208 patients, 93.8% had no prior ART exposure, 3.8% reinitiated the same regimen, 2.4% had unknown prior ART exposure; and 31.3% had a CD4 count <200 cells/µl. Mutations associated with resistance were present in 15.4% of patients. Mutations associated with resistance to nonnucleoside reverse transcriptase inhibitors (NNRTI) were present in 13.0% of patients, nucleoside reverse transcriptase inhibitors in 4.3%, and integrase inhibitors in 3.4%. Mutations associated with resistance to tenofovir were present in 1.0% of patients and emtricitabine/lamivudine in 1.4%. ​​Nearly one in six patients had PDR in Paraguay's first nationally representative sample. High NNRTI PDR prevalence underscores the need to accelerate the transition to dolutegravir‐based first‐line ART. The low PDR prevalence of tenofovir and emtricitabine is reassuring as these ARVs are part of the World Health Organization (WHO)‐recommended oral pre‐exposure prophylaxis regimen. The high proportion of individuals initiating ART at a late disease stage highlights the need to improve treatment linkage strategies and implement WHO rapid ART initiation recommendations.

This paper examines in detail the morpho-syntax of the verbal phrase in Paraguayan Guarani, in root and complement clauses, and argues that while the ordering relation between the verb and its associated functional morphemes is congruent with the syntax (cf. the Mirror Principle), the ordering of post-verbal arguments is best understood in terms of phonological linearization. More specifically, it is argued that there are language-particular prosodic requirements that force the post-verbal arguments to be phonologically linearized outside the accentual domain defined by the verb and its associated functional morphemes.

The Jesuit missions in South America were an important factor in the evangelisation of the continent during the seventeenth and eighteenth centuries. However, although the history and cultural aspects of the distinctive settlements that the missionaries created for indigenous peoples have been examined extensively, studies that address issues relating to archaeoastronomy have only recently begun to appear, primarily in relation to the orientation of churches built for Guaraní peoples in the Jesuit Province of Paraquaria (Province of Paraguay). The current paper continues and complements these studies of the region with the first archaeoastronomical study of the nearby Jesuit missions of Chiquitos in eastern Bolivia, focusing on measurements taken at the ten mission churches, interpreted within the context of the surrounding landscape and the characteristics of the villages where the churches are located. Our results show that in contrast to the churches of the Province of Paraquaria, where north-south meridian orientations predominate, half of the studied Chiquitan Jesuit churches show potential canonical orientations that seem to be aligned to solar phenomena, with three exhibiting precise equinoctial orientation. In this paper I propose reasons for these orientations, including the possible relevance of illumination effects on significant internal elements within the churches - effects that were generally sought in Baroque church architecture.

The paper shows mechanisms and manifestations of the challenges for the security in the South American Tri-Border Area (Paraguay, Brazil and Argentina). It analyses the background of the activity of chosen organized crime and terrorist groups in this region. The article refers to some social and economic conditions for the spread of violence and illegal business in the area. It is focused on the most important dimensions of these problems and on the strategy implemented by South American governments to fight and prevent organized crime. The paper shows how the security forces deal with the threat and evaluate the impact of these efforts. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this paper is to do a systematic assessment and testing of identified human rights norms alongside social determinant approaches in relation to identified health issues of concern in four Latin American countries (Argentina, Chile, Paraguay and Uruguay) to show how social determinants and human rights frameworks improve population health. Design/methodology/approach: To do so, in the first part the authors analyze the inequalities both between and within each of the selected countries in terms of health status and health determinants of the population. Then, in the second section, the authors analyze the level of recognition, institutionalisation and accountability of the right to health in each country. Findings: From the data used in this paper it is possible to conclude that the four analysed countries have improved their results in terms of health status, health care and health behaviours. This improvement coincides with the recognition, institutionalisation and creation of accountability mechanisms of human rights principles and standards in terms of health and that a human rights approach to health and its relation with other social determinants have extended universal health coverage and health systems in the four analysed countries. Originality/value: Despite of the importance of the relation between human rights and social determinants of health, there are few human right scholars working on the issues of social determinants of health and human rights. Most of the literature of health and human rights has been focussed specific relations between specific rights and the right to health, but less human right scholar working on social determinants of health. On the other hand, just a few epidemiologists and people working on social medicine have actually started to use a universal human rights frame and discourse. In fact, according to Vnkatapuram, Bell and Marmot: "while health and human rights advocates have from the start taken a global perspective, social medicine and social epidemiology have been slower to catch up".

Developing countries are especially vulnerable to climate change, as they often depend on agriculture and have less adaptation possibilities. The present paper assesses the economic implications of climate change in Paraguay, by incorporating projected crop productivity impacts due to climate change in a global multi-region and multi-sector general equilibrium model. The results suggest that despite projected decreases in crop productivity Paraguayan production and exports of wheat and soybeans may increase because of climatic changes, and lead to increased household income and welfare in Paraguay. This is because the projected decreases in crop productivity are generally larger in other regions than in Paraguay, giving the competitive advantage, allowing Paraguay to increase their share on global and regional soybean, wheat, and rice markets. Although these results seem promising for Paraguay, it highlighted the need for future improvements in estimating climate impact on crops at regional and global levels considering integrated agricultural and economic models.

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.

Purpose: This study explores the determinants of growth of credence-based exports of yerba mate from Paraguay, potential for increased export growth, and the fragility of the credence-based export model. Much of the growth in value of yerba mate exports from Paraguay is due to positioning of the good within the universe of products where consumption is driven by perceptions of sustainable production and health benefits to consumers. Credence claims for yerba mate—benefits to indigenous producing communities, environmental sustainability under certain production processes, healthful alternatives to energy drinks—are now widely known, but the growth of this awareness came via a new entrepreneurial strategy of a single firm. Design/methodology/approach: Primary information was collected through interviews of actors in the Paraguayan yerba mate value chain during spring/summer 2020. These included representatives from three exporting companies, processors, public institutions and indigenous producers. Findings: The Paraguayan yerba mate export boom was stimulated through the careful cultivation of an image of healthful consumption and sustainable production processes. The cost of this cultivation was borne mainly by a single firm. Findings suggest that future marketing efforts will need to reinforce credence claims, highlighting the benefits to indigenous producers. Research limitations/implications: This case study explores the determinants of growth of credence-based exports of yerba mate from Paraguay, potential for increased growth, and the fragility of the credence-based model. Originality/value: Findings are supported by field interviews with value chain participants and detailed analysis of extant data. The paper is the first to discuss the fragility of relying on credence attributes for long-term demand growth. [ABSTRACT FROM AUTHOR]

Eugenia uniflora linnaeus, known as Brazilian cherry, is widely distributed in Brazil, Argentina, Uruguay, and Paraguay. E. uniflora L. extracts contain phenolic compounds, such as flavonoids, tannins, triterpenes, and sesquiterpenes. The antimicrobial action of essential oils has been attributed to their compositions of bioactive compounds, such as sesquiterpenes. In this paper, the fruit extract of E. uniflora was used to synthesize silver and gold nanoparticles. The nanoparticles were characterized by UV–Vis, transmission electron microscopy, elemental analysis, FTIR, and Zeta potential measurement. The silver and gold nanoparticles prepared with fruit extracts presented sizes of ~32 nm and 11 nm (diameter), respectively, and Zeta potentials of −22 mV and −14 mV. The antimicrobial tests were performed with Gram-negative and Gram-positive bacteria and Candida albicans. The growth inhibition of EuAgNPs prepared with and without photoreduction showed the important functional groups in the antimicrobial activity. [ABSTRACT FROM AUTHOR]

Background: Irrational antimicrobial consumption (AMC) became one of the main global health problems in recent decades. Objective: In order to understand AMC in Latin-American Region, we performed the present research in 6 countries. Methods: Antimicrobial consumption (J01, A07A, P01AB groups) was registered in Argentina, Chile, Colombia, Costa Rica, Paraguay, and Peru. Source of information, AMC type, DDD (Defined Daily Doses), DID (DDD/1000 inhabitants/day), population were variables explored. Data was analyzed using the Global Antimicrobial Resistance and Use Surveillance System (GLASS) tool. Results: Source of information included data from global, public, and private sectors. Total AMC was highly variable (range 1.91-36.26 DID). Penicillin was the most consumed group in all countries except in Paraguay, while macrolides and lincosamides were ranked second. In terms of type of AMC according to the WHO-AWaRe classification, it was found that for certain groups like "Reserve," there are similarities among all countries. Conclusion and Relevance: This paper shows the progress that 6 Latin-American countries made toward AMC surveillance. The study provides a standardized approach for building a national surveillance system for AMC data analysis. These steps will contribute to the inclusion of Latin-America among the regions of the world that have periodic, regular, and quality data of AMC. [ABSTRACT FROM AUTHOR]

This paper presents the first sociophonetic study of Sanapaná (Enlhet-Enenlhet), spoken by around one thousand people in Paraguay. It examines the effects of L2 (Spanish/Guaraní) fluency and loss of L1 exposure on vowel quality and within-category variability of /e, o/ productions in the Sanapaná /e, a, o/ system. Data from eleven native Sanapaná speakers suggest that age and multilingualism may have little explanatory power by themselves. Speakers living in a majority-L2 environment show greater within-category variability and increased convergence of /e, o/ toward the L2 high vowels /i, u/ than daily users of Sanapaná. This suggests that decreased L1 exposure is the main factor driving language shift-related change in Sanapaná. I explain these findings in an exemplar-theoretic framework. Although the number of speakers sampled is limited, these data provide a valuable addition to our knowledge of sociolinguistic variation in small, underrepresented communities.

This paper contributes to the lack of longitudinal studies concerning online information access to corporate governance (CG) practices in the banking sector of Latin American countries. In particular, this study aims to analyze the factors that influence information transparency, both mandatory and voluntary, related to CG practices of banks that operate in Paraguay via their websites from 2016 to 2019. Findings indicate the need to improve the level of information available on websites, with disclosure of voluntary information on CG practices being more prevalent than the disclosure of mandatory information. Likewise, banks that operate in Paraguay have made scant "progress" regarding online access to their governance information over the years analyzed. Moreover, the factors "Bank size" and "listed status" positively influence the information transparency regarding CG practices of Paraguayan banks. In contrast, "leverage," "liquidity," "size of the audit firm," and "credit risk rating" are factors that have a negative relation with the extent of CG disclosure. [ABSTRACT FROM AUTHOR]

The drought resistance mechanism of typical mosses in the karst area was studied, and the water and photosynthetic physiological adaptation of mosses to karst environmental change was analyzed in this paper, which provided the basis for the restoration and control of karst rocky desertification ecological environment. Three superior plants in the rocky desertification area of Guizhou province were selected; they are, respectively, Erythrodontium julaceum (Schwaegr.) Par., Barbula unguiculata Hedw., and Bryum argenteum Hedw. Results show that the three kinds of plant rock mosses of leaf water potential (Ψs), free water content ( V a ), total water content, and relative water content (RWC) decreased; bound water ( V s ), water saturation deficit (WSD), and V s / V a ratio increased; transpiration rate (Tr) fell slightly, under drought stress. The physiological indexes of water have different degrees of recovery after rehydration. The total chlorophyll content shows a trend of first increasing followed by falling and then rising. RWC was negatively related to qN and positively related to F v / F m , yield, ETR, and qP. After rewetting, the fluorescence parameters are returned to average level under mild-to-moderate stress. At the same time, it is hard to get back to the control level under severe pressure. The water use efficiency (WUE) decreased with stress and recovered to different degrees after rehydration.

Aim: Mapping species distributions is a crucial but challenging requirement of wildlife management. The frequent need to sample vast expanses of potential habitat increases the cost of planned surveys and rewards accumulation of opportunistic observations. In this paper, we integrate planned‐survey data from roost counts with opportunistic samples from eBird, WikiAves and Xeno‐canto citizen‐science platforms to map the geographic range of the endangered Vinaceous‐breasted Parrot. We demonstrate the estimation and mapping of species occurrence based on data integration while accounting for specifics of each dataset, including observation technique and uncertainty about the observations. Location: Argentina, Brazil and Paraguay. Methods: Our analysis illustrates (a) the incorporation of sampling effort, spatial autocorrelation and site covariates in a joint‐likelihood, hierarchical, data integration model; (b) the evaluation of the contribution of each dataset, as well as the contribution of effort covariates, spatial autocorrelation and site covariates to the predictive ability of fitted models using a cross‐validation approach; and (c) how spatial representation of the latent occupancy state (i.e. realized occupancy) helps identify areas with high uncertainty that should be prioritized in future fieldwork. Results: We estimate a Vinaceous‐breasted Parrot geographic range of 434,670 km2, which is three times larger than the "Extant" area previously reported in the IUCN Red List. The exclusion of one dataset at a time from the analyses always resulted in worse predictions by the models of truncated data than by the Full Model, which included all datasets. Likewise, exclusion of spatial autocorrelation, site covariates or sampling effort resulted in worse predictions. Main conclusions: The integration of different datasets into one joint‐likelihood model produced a more reliable representation of the species range than any individual dataset taken on its own, improving the use of citizen‐science data in combination with planned‐survey results.
