A CONCEPTUAL FRAMEWORK FOR CASE STUDY ANALYSIS ON THE INTERNATIONALIZATION OF LATIN AMERICAN COMPANIES

A conceptual framework for case study analysis is developed through qualitative meta-analysis on N=26 articles on the internationalization of Latin American companies in countries with a GDP of more than $ 100 billion, published between 2010 and 2018. Key findings revealed a matrix comprising nine dimensions, and suggest that case studies should be improved through consistent (i) statement of the unit of analysis, (ii) the diversification of the use of data collection sources, and (iii) the use of analysis software for qualitative research. This article is provided scholars with a new perspective and taxonomy on the case study analysis, and implications of these findings are discussed

Guerra e Negócios: o que a Literatura Tem a Dizer sobre o Assunto?

This article aims to analyze the contemporary scientific production that relates war to business through an exploratory review of the corresponding literature in which we sought to identify the main research themes and theoretical-empirical contributions on the topic. As a result, it was observed that war entails both risks and opportunities for business, presenting itself as a dichotomous environment: at times propelling, at times repulsive of investments. Another aspect highlighted in this work refers to the dispersion of literature in different areas of knowledge, which has made it difficult to build a research agenda that explores the multifaceted nature of the phenomenon. In that regard, the purpose of this article is to contribute to the articulation of such evidence by generating seven theoretical propositions and an analytical framework to point out research opportunities related to the topic in question.Este artigo objetiva analisar a produção científica contemporânea sobre a temática que relaciona a guerra com os negócios por meio da revisão exploratória da literatura correspondente, em que procurou-se identificar os principais temas de pesquisa e as contribuições teórico-empíricas acerca do tópico em tese. Como resultado da análise, observou-se que a guerra enseja tanto riscos como oportunidades para os negócios, apresentando-se como um ambiente dicotômico: ora propulsor, ora repulsor de investimentos. Outro aspecto evidenciado neste trabalho se refere à dispersão da literatura associada ao tema entre diversas áreas do conhecimento, o que tem dificultado a construção de uma agenda de pesquisa que explore a natureza multifacetada do fenômeno analisado. Nesse sentido, o propósito deste artigo é contribuir para a articulação de tais evidências por meio da geração de sete proposições teóricas e de um framework analítico para apontar oportunidades de pesquisa referentes ao tema em questão

Producción primaria y dinámica del fitoplancton en un estuario subtropical: un enfoque múltiple de escalas de tiempo

Temporal variability of physicochemical parameters and phytoplankton primary productivity, abundance and composition were investigated at Babitonga Bay, southern Brazil, using a hierarchical sampling design on the scales of months, weeks and days during spring 2012 and summer 2013. Only temperature, respiration rates and concentrations of dissolved oxygen and silicate exhibited significant differences in the greatest timescale (seasons: spring; summer). In contrast, most physicochemical parameters, such as salinity and the concentration of nitrogen compounds, varied mainly among weeks and days. This short-scale variability was similarly observed for the microphytoplankton abundance, ranging from 0.04 to 1.7.106 cells L–1 during a bloom of the diatom Skeletonema costatum. Two major phytoplankton assemblages were associated with high primary production rates: > 30 μm centric diatoms such as Cyclotella spp. and Cymatodiscus sp., in spring; and a summer assemblage dominated by smaller, bloom-forming diatoms (S. costatum and Eucampia cornuta). Primary production ranged from 10.5 to 1793 mg C m–2 d–1 and varied significantly between days and months, being associated with the photosynthetic active radiation level and weather conditions on the sampling day. Abundance of specific plankton taxa appeared controlled by trophic interactions, as revealed for the mixotrophic, toxic dinoflagellate Dinophysis acuminata complex and its prey, the ciliate Mesodinium rubrum.Se investigaron la variabilidad temporal de los parámetros físico-químicos y la producción primaria (PP), abundancia y composición del fitoplancton en la Bahía de Babitonga, sur de Brasil, utilizando un diseño de muestreo jerárquico en las escalas de meses, semanas y días, durante la primavera/2012 y verano/2013. Sólo la temperatura, las tasas de respiración y las concentraciones de oxígeno disuelto y silicato mostraron diferencias significativas en las escalas de tiempo mayores (estaciones: primavera; verano). En contraste, la mayoría de los parámetros fisicoquímicos, tales como la salinidad y la concentración de compuestos de nitrógeno, varió principalmente entre semana y días. Tal variabilidad de corta escala se observó de manera similar para la abundancia de microfitoplancton, oscilando desde 0,04 a 1.7.106 céls. L–1 durante una floración de la diatomea Skeletonema costatum. Se asociaron dos importantes grupos de fitoplancton con altas tasas de PP: diatomeas céntricas > 30 μm como Cyclotella spp. y Cymatodiscus sp., en primavera; y un grupo de verano dominado por pequeñas diatomeas formadoras de floraciones (S. costatum y Eucampia cornuta). La PP varió de 10.5 a 1793 mg C m–2 d–1 y varió significativamente entre días y meses, siendo asociada con el nivel de radiación fotosintética activa y las condiciones meteorológicas en el día de muestreo. La abundancia de taxa específicos de plancton parece controlada por interacciones tróficas, como las revelada para el dinoflagelado tóxico mixotrófico, complejo Dinophysis acuminata y su presa, el ciliado Mesodinium rubrum
