Corporate governance research is often limited in its ability to employ within-firm estimators, which address time-invariant endogeneity, when the variables of interest exhibit low time variation (for example, ownership and board independence). The problem is further exacerbated if data for multiple points in time needs to be hand-collected. We offer simulation-based methodological guidance to improve the statistical power of within-firm estimators in the presence of low time variation. We illustrate the usefulness of our simulation results by replicating two influential studies on ownership and board independence and extending them with a within-firm estimator. Based on widely used databases as well as a novel granular database, we document the different degrees and nature of time variation of ownership and board independence across jurisdictions and subgroups by listed status, family c...

La ingestión de nitrógeno líquido es una causa infrecuente de perforación gástrica, se conoce poco sobre como este compuesto afecta el tejido gastrointestinal, sus mecanismos de lesión y sus consecuencias clínicas. Cada vez es más frecuente el uso del nitrógeno líquido de forma comercial en productos de repostería y gastronomía, por lo que es importante reconocer sus potenciales efectos cuando la manipulación no es la adecuada. En este caso clínico describimos una perforación gástrica secundaria al consumo de helado preparado con nitrógeno líquido.

Forced displacement, the crime with the largest number of victims of the Colombian armed conflict, has few analyses emphasizing mental health. This article presents a characterization of this phenomenon, delving into issues of poverty, vulnerability, and types of mental health care for victims. Two methodological approaches are used: a quantitative one, complementing data from a psychiatric care center with information from Sisbén, a database with socioeconomic information used to classify the population according to their living conditions, and a qualitative one, examining patients’ clinical records. Thus, the text describes how the displaced population faces multiple vulnerabilities that combine victimization, poverty, and mental health affectations. This research confirms the high prevalence of depressive and anxiety disorders as reported in the literature. It was found that, despi...

El presente trabajo de investigación tiene por objeto la creación y comercialización de una bolsa ecológica reutilizable; la cual cuenta con un forro impermeable que permite multifuncionalidad siendo así, de fácil transporte y limpieza. Además, un cierre impermeable que asegura los productos dentro de la bolsa. Diseñada principalmente para el transporte de diversos productos frescos o que estén helados. Este producto contribuirá con la disminución de bolsas plásticas de uso único, ayudando al cuidado del medio ambiente y la adecuada conservación de los alimentos. Esta idea de negocio nace de la necesidad de una opción eco amigable, ya que el uso de bolsas plásticas en nuestro país no ha cesado a pesar de que su uso ha sido restringido. Añadido a esto, los productos actuales que ofrecen las empresas no son adecuados, ya que se enfocan principalmente en cubrir necesidades...
