Resumen: El comercio electrónico del sector de la moda ha aumentado en los últimos años en Latinoamérica, especialmente a raíz de la pandemia, sin embargo, todavía existen problemas en la aceptación de este canal de compra. La presente investigación se centra en algunos factores que podrían influir en la intención de compra y tiene como objetivos comprobar cómo en ella influyen la confianza, los riesgos percibidos, los costos y la conveniencia. Para esto, se suministró un cuestionario a 223 estudiantes de cuatro universidades del Ecuador. Para el análisis de los datos obtenidos se desarrolló un modelo PLS-SEM, en el cual la confianza en el vendedor actúa como variable mediadora en la relación entre los otros tres factores y la intención de compra. Los resultados muestran que dicho modelo tiene un aceptable poder predictivo y explicativo. Asimismo, se comprueba que los riesgos, la conveniencia y la confianza afectan significativamente a la intención de compra, pero no los costos. Además, la confianza mediaría la relación entre las tres variables y la intención de compra en línea. Se concluye que el modelo propuesto puede servir de base para estudios similares y, a su vez, se considera que los resultados obtenidos pueden ser utilizados por las empresas en el sector de la moda que quieren vender a través de plataformas de e-Commerce para el desarrollo de estrategias de marketing.

Abstract: E-commerce in the fashion sector has increased in recent years in Latin America, especially in the wake of the pandemic, however, there are still issues in the acceptance of this shopping channel. The present research focuses on some factors that could influence purchase intention and aims to test how it is influenced by trust, perceived risks, costs and convenience. For this purpose, a questionnaire was given to 223 students from four universities in Ecuador. A PLS-SEM model was developed for the analysis of the data, in which trust in the seller has a mediating role in the relationship between the other three factors and purchase intention. Results show that this model has acceptable predictive and explanatory power. Likewise, it validates that risks, convenience and trust significantly affect intention, but not costs. In addition, trust would mediate the relationship between the other variables and online shopping intention. It is concluded that the proposed model can serve as a basis for similar studies, and, at the same time, it is considered that the results obtained can be used by business in the fashion sector that pursue to sell through e-commerce platforms for marketing strategies development.

Abstract As a result of COVID-19, new dynamics emerged in many urban systems, including the acquisition and distribution of food. The pandemic revealed vulnerabilities in the functioning of facilities and intensified problems such as informality, insecurity, and immigration. In order to contribute to the identification and characterization of these dynamics within food markets, a case study methodology was adopted for this article using mixed techniques - a quantitative approach using a survey and a qualitative approach featuring a focus group. Both methods were applied in the San Roque market in the Metropolitan District of Quito, an iconic food market and distribution facility. The results highlight new commercial dynamics and preferences, as in recent years informal trade and the presence of supermarket chains have proliferated; new logistic means have been created; and wholesale trade has intensified. In addition, the pandemic accentuated the vulnerability of the market at the administrative level and the precariousness of some informal jobs, in turn, accelerated changes among traders. It is concluded that these dynamics merit new conceptual, organizational, and spatial approaches in architectural and urban terms, as well as different policies that favor the sustainable management of markets.

Resumen A raíz de la covid-19 se dieron nuevas dinámicas en muchos sistemas urbanos entre las que destaca la de adquisición y distribución de alimentos. La pandemia mostró la vulnerabilidad en el funcionamiento de equipamientos e intensificó problemáticas como la informalidad, la inseguridad y la inmigración. Con el objetivo de aportar a la identificación y caracterización de estas dinámicas dentro de los mercados de alimentos, para el presente artículo se adoptó una metodología de caso de estudio con técnicas mixtas: cuantitativas por medio de una encuesta y cualitativas a partir de un grupo focal. Ambas técnicas se aplicaron en el mercado San Roque en el Distrito Metropolitano de Quito, equipamiento icónico en cuanto a la comercialización y distribución de alimentos. En los resultados sobresalen las nuevas dinámicas y preferencias comerciales, ya que en los últimos años han proliferado el comercio informal y la presencia de cadenas de supermercados, se han creado nuevos medios logísticos y se ha intensificado el comercio mayorista. Además, la pandemia acentuó la vulnerabilidad del mercado a nivel administrativo y la precarización de algunos trabajos informales, a su vez, aceleró un cambio entre el grupo de comerciantes. Se concluye que estas dinámicas ameritan nuevas aproximaciones conceptuales, organizativas y espaciales a escala arquitectónica y urbana, y también distintas políticas que favorezcan la gestión sostenible de los mercados.

Resumen Este artículo profundiza en el conocimiento sobre la Lleuda de Mediona, una tasa sobre la compraventa de productos alimentarios, materias primas y ropa que fue aplicada en la ciudad de Barcelona en período preindustrial. Con el uso de documentación inédita de carácter contencioso o normativo, se presenta el origen y la evolución del impuesto entre los siglos XIII y XIV. Pare ello, se describen en sendas secciones gravámenes especiales ligados a la Lleuda: el mesuratge que afectaba la comercialización del aceite, y el quint del cuiram, aplicado sobre el comercio del cuero y de la cochinilla, materias generalmente importadas de las regiones islámicas del sur del Mediterráneo. El artículo subraya la importancia de estos productos en la economía urbana del momento. Finalmente, el estudio describe aspectos desconocidos sobre el origen de la Lleuda y de su mecánica.

Abstract This article focuses on the so-called Lleuda de Mediona, a tax on the sale of foods, raw materials and cloth applied in the city of Barcelona during pre-Modern times. With the use of unpublished sources of litigious and/or regulatory nature, the origin and evolution of the tax between the thirteenth and fourteenth centuries are discussed. Two separate sections describe special charges that were directly linked to the Lleuda: the socalled mesuratge, that affected the marketing of olive oil; and the quint of cuiram, applied to the trade of leather and cochineal. The latter were commodities usually imported from the Islamic regions of the southern shore of the Mediterranean. The article underlines the importance of these products in the urban economy of the period. Finally, this study describes some features about the origins of the Lleuda and its mechanics.

ABSTRACT Financing is relevant to deal with business crises, even more after the COVID-19 pandemic, therefore, the objective of the study is to determine the influence of the characteristics of the companies and the managers of the organizations registered in the Chamber of Commerce and Industry of Azogues on the decision of additional financing during the health crisis, for this a questionnaire was applied to 135 partners. Using Spearman's correlation and binary logistic regression, it is evident that the characteristics of the companies (economic sector, legal structure, experience, number of workers, paralysis of activities and capital structure) partially influence the decision of additional financing, given that only the capital structure has a positively significant relationship with the treatment variable, while the characteristics of the manager (age, sex, level of education and years of experience) have no influence.

RESUMEN El financiamiento es relevante para afrontar las crisis empresariales, más aún luego de la pandemia por la COVID-19, por tanto, el objetivo del estudio es determinar la influencia de las características de las empresas y de los directivos de las organizaciones registradas en la Cámara de Comercio e Industrias de Azogues en la decisión de financiamiento adicional durante la crisis sanitaria, para lo cual, se aplica un cuestionario a 135 socios. Mediante el uso de correlación de Spearman y regresión logística binaria, se evidencia que las características de las empresas (sector económico, estructura legal, experiencia, número de trabajadores, paralización de actividades y estructura de capital) influyen parcialmente en la decisión de financiamiento adicional, dado que únicamente la estructura de capital tiene una relación positivamente significativa con la variable de tratamiento, mientras que las características del administrador (edad, sexo, nivel de educación y años de experiencia) no tienen ninguna influencia.

Abstract This study aims to investigate the influence of user experience and online security on customer satisfaction and trust in e-commerce. The research method included a structural equation modeling that relates perceived security, user experience, trust, and customer satisfaction online. The findings showed that user experience and perceived security are significant factors that influence trust, and consequently, customer satisfaction. The relevant finding was to identify trust as the main factor in predicting customer satisfaction. The study's value is to provide companies with the opportunity to implement strategies based on trust and customer satisfaction online, which have been poorly studied in Mexico previously. The main limitation was the use of a specific sample of online consumers in Mexico; thus, the results may not be generalizable to other populations.

Resumen El objetivo es investigar la experiencia del usuario y la seguridad en línea como influencias de satisfacción y la confianza del cliente de e-commerce. El método de investigación incluyó un modelo de ecuaciones estructurales que relaciona la seguridad percibida, la experiencia del usuario, la confianza y la satisfacción del cliente en línea. Los resultados demostraron que la experiencia y la percepción de seguridad son factores importantes que influyen en la confianza y, en consecuencia, en la satisfacción. El hallazgo relevante fue identificar a la confianza como factor principal para predecir la satisfacción del cliente. El valor del estudio es brindar a empresas la oportunidad de implementar estrategias basadas en la confianza y la satisfacción del cliente en línea, poco estudiadas previamente en México. La limitación principal fue el uso de una muestra específica de consumidores en línea en México, por ello, los resultados pueden no ser generalizables a otras poblaciones.

In many South African universities, full research students receive little support during the research conceptualisation stage of the research journey, other than that provided by their supervisors, who tend to have limited time to engage with their students. Furthermore, during the proposal phase, scant attention is paid to the role of writing in research conceptualisation and scholarly development. In an attempt to address this neglect, the authors of this article worked collaboratively with academic staff from two schools within the Faculty of Commerce, Law, and Management at the University of the Witwatersrand to pilot academic literacies-informed projects aimed at integrating writing in the first year of existing postgraduate research programmes. This article provides insight into factors that constrain and enable such an integration endeavour. Data was collected through focus group discussions with the project teams from the participating schools. Drawing on Margaret Archer's structure, culture, and agency as the analytical framework, five themes emerged from the data: leadership and oversight, supervision and postgraduate pedagogy, supervisor awareness and support, the postgraduate research education curriculum, and student engagement and commitment. The authors discuss these themes in terms of their enabling and constraining dimensions, and conclude with observations that could inform similar initiatives in other postgraduate research programmes.

RESUMEN El cacao ha aportado sustanciales ingresos a la economía ecuatoriana, al punto de llamársele “pepa de oro” desde el siglo XIX, por ser la base de las primeras industrias y entidades bancarias y dinamizador del desarrollo socio-económico. En la cadena de producción y comercialización cacaotera intervienen múltiples actores, estableciéndose interrelaciones para posicionar los productos del cacao en el mercado interno, pero destinando la mayor parte a la exportación. Este estudio analiza el proceso de comercialización de productos a partir de la identificación de sus principales canales. Sobre la base de una metodología mixta con enfoque descriptivo, se caracterizó el producto y su comercialización a partir de los resultados de una encuesta a actores del sector comercio de la provincia de Manabí. Se demuestra la preferencia por el consumo de productos del cacao procedentes de distribuidoras locales con políticas de pago flexibles, ciclos operativos de reposición de productos y respetuosas de las normativas legales y sanitarias. Entre los derivados con mayor consumo se encuentra el chocolate en polvo y el chocolate en barra, con preferencias hacia los envases en funda y sachets. Los resultados pueden ser generalizados a otras localidades, para potenciar la comercialización de productos derivados del cacao.

ABSTRACT Cocoa has contributed substantial income to the Ecuadorian economy, to the point of being called “golden nugget” since the 19th century, for being the basis of the first industries and banking entities and driving socio-economic development. Multiple actors intervene in the cocoa production and marketing chain, establishing interrelationships to position cocoa products in the domestic market, but allocating the majority to export. This study analyzes the product marketing process by identifying its main channels. Based on a mixed methodology with a descriptive approach, the product and its marketing were characterized based on the results of a survey of actors in the commerce sector in the province of Manabí. The preference for the consumption of cocoa products from local distributors with flexible payment policies, operational product replacement cycles and respect for legal and health regulations is demonstrated. Among the derivatives with the greatest consumption are chocolate powder and chocolate bars, with preferences towards packaging in cases and sachets. The results can be generalized to other locations, to enhance the marketing of cocoa products.

RESUMEN El objetivo del presente artículo es analizar cuáles son los factores que inciden en la adopción del comercio electrónico por parte de las pymes en Guayaquil. La importancia e impacto que tiene el E-Commerce en las organizaciones es de gran magnitud en diferentes aspectos, es por ello que se han estudiado varios modelos de adopción de E-Commerce. Algunos de estos modelos estudiados son los de Kabanda & Brown modelo integrado de adopción de E-Commerce donde se mencionan tres factores relevantes como el organizacional, de innovación y ambiental, por otra parte, también se tiene el modelo de adopción de E-Commerce para pymes de Wang & Hou, donde definen el contexto tecnológico, organizacional y ambiental como factores determinantes en la adopción del E-Commerce. El factor organizacional hace referencia a las características propias de la organización y de los propietarios en el momento de adoptar las tecnologías de E-Commerce, mientras que el factor de innovación analiza los aspectos del por qué un usuario acepta o rechaza las nuevas innovaciones por medio del modelo de aceptación de tecnología. Para el desarrollo de este trabajo se emplea metodología de tipo descriptivo y método cuantitativo; se realiza una encuesta, a la muestra de 67 pymes comerciales de Guayaquil. En conclusión, se identifican los factores que influyen en la adopción del comercio electrónico por parte de las pequeñas y medianas empresas (pymes) en Guayaquil, revelando aspectos tecnológicos, organizativos, de innovación y transaccionales. Estos factores ejercen tanto impactos positivos como negativos durante el proceso de adopción del comercio electrónico.

ABSTRACT The objective of this project is to analyze the factors influencing the adoption of electronic commerce by small and medium-sized enterprises (SMEs) in Guayaquil. The importance and impact of E-Commerce on organizations are significant in various aspects, leading to the study of several E-Commerce adoption models. Some of these models, such as Kabanda & Brown's integrated E-Commerce adoption model, highlight three relevant factors: organizational, innovation, and environmental. Additionally, Wang & Hou's E-Commerce adoption model for SMEs defines technological, organizational, and environmental contexts as determining factors in E-Commerce adoption. The organizational factor refers to the characteristics of the organization and owners when adopting E-Commerce technologies, while the innovation factor analyzes aspects of why a user accepts or rejects new innovations through the technology acceptance model. This work employs a descriptive methodology and quantitative method, conducting a survey with a sample of 67 commercial SMEs in Guayaquil. In conclusion, factors influencing the adoption of electronic commerce by SMEs in Guayaquil are identified, revealing technological, organizational, innovation, and transactional aspects. These factors exert both positive and negative impacts during the E-Commerce adoption process.

ABSTRACT The COVID-19 pandemic imposed many market changes, driven partially by new consumer needs. In the electronic commerce field, changes occurred in parallel to an upsurge in demand, directly impacting logistics service quality. Within that context, this paper seeks a way of assessing the quality of e-commerce logistics, based on end-customer perceptions at the close of the purchasing cycle. The objective is thus to develop a mathematical model based on the artificial intelligence precepts that can interpret qualitative expressions captured through a questionnaire. Such values form partial indexes and the E-Commerce Logistics Quality Index (IQLE). After processing 180 records, it was noted that three of the seven analyzed attributes scored below 5.0, denoting some concern, but also opening up opportunities for improvement and the development of marketing solutions.

RESUMO É fato que com a pandemia da COVID-19 ocorreram muitas mudanças de mercado, em parte, impulsionadas pelas novas necessidades dos consumidores. No âmbito do comércio eletrônico, as mudanças aconteceram em paralelo com o aumento rápido de demanda, impactando diretamente na qualidade do serviço logístico prestado. É nesse contexto que este artigo busca desenvolver uma forma de avaliar a qualidade da logística do e-commerce, baseando-se na percepção do cliente final ao final do ciclo do pedido. Para tanto, objetiva-se desenvolver um modelo matemático, baseando-se nos preceitos da inteligência artificial, que possa interpretar expressões qualitativas, capturadas por intermédio de questionário, transformando-as em valores quantitativos, passíveis de análise no mundo real. Tais valores formam índices parciais e o IQLE (Índice da Qualidade da Logística do E-commerce). Após o processamento de 180 registros, observou-se que dos sete atributos analisados, três deles redundaram em nota abaixo de 5,0, denotando certa preocupação, mas oportunidade de melhora e desenvolvimento de soluções mercadológicas.

ABSTRACT This article presents and analyzes the history and connections among various black bookstore experiences in Southeast Brazil between 1972 and 2018. Given the lack of research on the topic in Brazil, this study relies heavily on structured interviews with some of the individuals in the sector, as well as on the analysis of secondary data and news. The stores studied are Livraria Contexto, Livraria Eboh, Livraria Griot, Sobá Livraria e Café, Kitabu Livraria Negra, Iná Livros and Livraria Africanidades, located in the states of São Paulo, Minas Gerais and Rio de Janeiro. They are owned by black women and men devoted to selling black and African literature, some of whom have been activists in different segments of Brazil’s black movements. Our findings have advanced a deeper understanding of the social meanings black traders assign to their activity, their reach, the connections among their purposes, and their limitations.

RESUMO Limitando-se à ordenação moral do comércio defendida por Aquino, afirma-se que, como efeito inverso de estancar a interpretação, a Suma teológica tanto motivou a alimentação do imaginário cristão em narrativas como A divina comédia, de Dante Alighieri, de modo a ampliar a reflexão sobre as categorias dos pecadores pelo dinheiro, como também forneceu subsídios para a construção de antimodelos em parte das narrativas emolduradas da obra Contos da Cantuária, de Geoffrey Chaucer, recheada de tipos avarentos, simoníacos e fraudadores. Este artigo objetiva apresentar as instruções de Aquino a respeito dos usos do dinheiro, cotejando, em alguns momentos, com textos literários. Para isso, passagens bíblicas, comentadores da Bíblia de tradição católica e textos de economistas são trazidos à medida que o texto da Suma teológica é analisado. Teóricos do pensamento cristão, como Agostinho e Boécio, e do pensamento econômico, como Molina e Robbins, são utilizados. Limitandose Limitando se afirmase afirma interpretação comédia Alighieri dinheiro Cantuária Chaucer avarentos fraudadores cotejando momentos literários isso bíblicas analisado Boécio econômico Robbins utilizados

ABSTRACT As a reverse effect of constraining interpretation and limiting itself to the moral ordering of commerce defended by Aquinas, the Summa Theologica both motivated the enrichment of the Christian imaginary in narratives like Dante Alighieri’s Divine Comedy and Geoffrey Chaucer’s work, The Canterbury Tales. In the case of the Divine Comedy, it expanded the reflection on the categories of sinners related to money, and as regards The Canterbury Tales, it provided support for the construction of anti-models in some of the framed narrative types of misers, simoniacs, and fraudsters. This article aims to present Aquinas’ instructions regarding the uses of money, juxtaposing, at times, with literary texts. For this purpose, biblical passages, commentators of the Catholic tradition Bible, and texts from economists are brought in as the Summa Theologica is analyzed. Theoretical thinkers of Christian thought, such as Augustine and Boethius, and economic thought, such as Molina and Robbins, have been used. Aquinas Alighieris Alighieri s Chaucers Chaucer work Tales money antimodels anti models misers simoniacs fraudsters juxtaposing times purpose passages Bible analyzed thought Boethius Robbins used

ABSTRACT Objective: To analyze the compliance with the commercialization of children's products included in the Brazilian Code of Marketing of Infant and Toddlers Food and Childcare-Related Products (NBCAL) in drugstores in Uberlândia/MG. Methods: A cross-sectional study was carried out in 143 drugstores that sold infant products: infant formula (IF), follow-up IF, nipples, teats, pacifiers and nipple shields; FI for young children, transition foods and cereal-based foods, fluid or powdered milk, modified/similar milks of plant origin and dairy compounds. The location of drugstores in the five geographic sectors was performed by geoprocessing. The data collected were: types of promotion and types of drugstore administration (drugstore chains/drugstores with independent administration). Irregular commercial promotion was expressed as absolute and relative frequencies. Results: Irregular commercial promotion was found in 11.7% of nipples, pacifiers and bottles, in 10.0% of IF and follow-up formula, in 9.5% of IF for young children, in 11.1% fluid or powdered milk, in 25.0% of transition foods and cereal-based foods and in 59.1% of dairy compounds. In commercial drugstore chains, the presence of promotion for dairy (81.8 vs. 28.6%, respectively) was higher than in drugstores with independent administration. The opposite ocurred for fluid or powdered milk, modified and similar milks of plant origin. The downtown and eastern sectors had the highest percentages of promotions (26%). Conclusions: NBCAL violations still occur in drugstores, mainly in the sale of young children's foods and in the commercial network drugstores.

RESUMO Objetivo: Analisar a conformidade da comercialização dos produtos infantis incluídos na Norma Brasileira de Comercialização de Alimentos para Lactentes e Crianças de Primeira Infância, Bicos, Chupetas e Mamadeira (NBCAL) e de compostos lácteos em drogarias de Uberlândia/MG. Métodos: Estudo transversal realizado em 143 drogarias que vendiam produtos infantis: fórmulas infantis (FI) para lactentes, FI de seguimento para lactentes, mamadeiras, bicos, chupetas e protetores de mamilo; FI para crianças de primeira infância, alimentos de transição e alimentos à base de cereais, leites fluidos/em pó, leites modificados/similares de origem vegetal e composto lácteo. A localização das drogarias nos cinco setores geográficos foi realizada por geoprocessamento. Os dados coletados foram: tipos de promoção comercial irregular e tipo de administração da drogaria (rede/independente). As promoções comerciais irregulares foram expressas em frequências absoluta e relativa. Resultados: Verificamos a presença de promoção comercial irregular em 11,7% dos bicos, chupetas e mamadeiras, em 10,0% das FI lactentes/seguimento de lactentes, em 9,5% das FI para crianças de primeira infância, em 11,1% dos leites, em 25,0% de alimentos de transição e em 59,1% dos compostos lácteos. Nas drogarias de rede, a presença de promoção comercial irregular foi maior para compostos lácteos (81,8 vs. 28,6%, respectivamente) e, para leites, foi maior nas drogarias independentes (30,8 vs. 6,0%). Os setores central e leste apresentaram os maiores percentuais de promoção comercial irregular (26%). Conclusões: As violações à NBCAL ainda ocorrem nas drogarias, principalmente para os produtos destinados às crianças de primeira infância, e nas drogarias de rede.

Résumé: L'objectif de la présente étude est d'identifier le contexte historique et la position actuelle du débat sur la mise en place d'une monnaie régionale entre le Brésil et l'Argentine. Cette recherche a été motivée par la proposition d'adopter une monnaie régionale pour les transactions commerciales bilatérales, lors de la visite officielle du dirigeant brésilien en Argentine le 23 janvier 2023. L'idée d'adopter une monnaie régionale entre ces deux pays n'est pas récente et a même été envisagée dans le cadre du Mercosur. Pour cette étude, la base de la recherche repose sur l'analyse des indicateurs économiques, des textes académiques, ainsi que des reportages journalistiques, des procès-verbaux de réunions et des normes du Mercosur. Cela a permis de comprendre comment la proposition a évolué au fil des années et dans quel contexte ces changements ont eu lieu. Cette étude se divise en trois phases distinctes. La première phase se concentre sur les avantages et inconvénients potentiels, ainsi que sur les impacts sur les coûts de transaction liés à l'adoption de devises alternatives dans le commerce bilatéral, en fournissant également la terminologie nécessaire. La deuxième phase se penche sur l'évolution historique de la proposition d'adopter une monnaie régionale, et dans la troisième phase, l'étude se focalise sur la proposition actuelle elle-même.

Resumo: A finalidade do presente estudo é identificar o panorama histórico e a posição atual do debate acerca da implementação de uma moeda de uso regional entre o Brasil e a Argentina. Essa pesquisa foi motivada pela proposta de adoção de uma moeda regional para uso nas transações comerciais bilaterais, por ocasião da viagem oficial do atual mandatário brasileiro à Argentina, em 23 de janeiro de 2023. A ideia de adoção de uma moeda regional, inclusive, ventilada entre esses dois países, não é recente e chegou a ser considerada no âmbito do Mercosul. Para o presente estudo foram utilizados como base da pesquisa a análise de indicadores econômicos, textos acadêmicos e, sobretudo, reportagens jornalísticas, atas de reuniões e a própria norma do Mercosul. Dessa forma, foi possível entender como a proposta mudou ao longo dos anos e em qual contexto isso ocorreu. Esse estudo possui três momentos distintos, o primeiro deles focado nas possíveis vantagens e desvantagens, bem como nos impactos nos custos de transação com a adoção de alternativas monetárias no comércio bilateral, além de prover a conceituação terminológica necessária. Em um segundo momento centrou-se na evolução histórica da proposta de adoção de uma moeda regional para que, em um terceiro momento fosse possível focar na proposta atual em si.

Abstract: The purpose of this study is to identify the historical context and current status of the debate surrounding the implementation of a regional currency between Brazil and Argentina. This research was motivated by the proposal to adopt a regional currency for bilateral commercial transactions, which was discussed during the official visit of the current Brazilian leader to Argentina on January 23, 2023. The idea of adopting a regional currency has been under consideration between these two countries for some time and was even discussed within the framework of Mercosur. For this study, the research is based on the analysis of economic indicators, academic texts, and, most importantly, news reports, meeting minutes, and the Mercosur norm itself. This allowed for an understanding of how the proposal has evolved over the years and in what context these changes occurred. This study can be divided into three distinct phases. The first phase focuses on the potential advantages and disadvantages, as well as the impact on transaction costs associated with the adoption of alternative currencies in bilateral trade. It also provides the necessary terminology and conceptual framework. In the second phase, the historical evolution of the proposal to adopt a regional currency is examined, and in the third phase, the current proposal itself is explored.

To evaluate the effects of glutamine (Gln) supplementation on sow performance during late gestation and lactation and their offspring, eighty pregnant, multiparous sows of a commercial hybrid line were used in a completely randomized, 2 χ 2 experimental design at the end of gestation and lactation, respectively. Females were subjected to a control diet or a Gln-supplemented diet (1% of L-glutamine) from 85 d of gestation until farrowing. During lactation, the dietary treatment groups were CON_C: without Gln supplementation; CON_G: Gln only during lactation; GLN_C: Gln only during gestation; GLN_ GLN: Gln during gestation and lactation. At 105 d of gestation, there was no statistical difference regarding the body weight of the sows, however, sows fed the Gln-supplemented diet had greater backfat thickness at P1 and loin depth at P2 than control sows. Placental weight and efficiency showed no effect between treatments. Litters born from Gln-supplemented sows tended to be heavier at birth compared to control litters, reducing the probability of piglets weighing less than 1.5 kg. In addition, litters from supplemented sows had a lower standard deviation of BW at birth. There were no effects of dietary treatments on the performance of sows and offspring during the lactation period. Maternal Gln supplementation during late gestation improved piglet weight and litter uniformity at birth without affecting sow body composition after farrowing.
