El presente artículo analiza el rol de la comunicación en el trabajo que realiza la Asociación Bartolomé Aripaylla (ABA) para rescatar los saberes y prácticas ancestrales sobre el uso y la conservación del agua en la comunidad campesina de Quispillaccta, distrito de Chuschi, provincia de Cangallo (Ayacucho). Para ello, se describe y analiza la propuesta de acompañamiento que tiene la organización para construir proyectos de desarrollo rural.

Orchid bees (Apidae: Euglossini) are endemic to the Neotropics, with 134 species recorded in Colombia. These bees are distinguished by being attracted to fragrances from various botanical families and play an important role in natural ecosystems. Research has primarily focused on these natural areas, which is why this study aims to evaluate the taxonomic diversity of orchid bees and their relationship to certain environmental factors in two peri-urban areas (Parque de la Iguana and Mirador de la Virgen) in the city of Yopal, Casanare Department, Colombia. Two types of sampling were conducted: transects (bottle method) and Zigzag, using eucalyptus, vanilla, eugenol, and methyl salicylate fragrances as attractants. The collected specimens were transported for taxonomic identification and preservation in the entomological collection. A total of 280 individuals (4 genera and 11 species) were...

El presente trabajo de suficiencia profesional titulado "Propuesta de implementación de control interno en las cuentas por cobrar y su impacto en la liquidez de la empresa Marketlogic Publicidad y Marketing Perú SAC 2023" tiene como objetivo principal optimizar la gestión de las cuentas por cobrar a través de un sistema de control interno basado en el modelo COSO. Se identificó que la falta de controles internos adecuados en las cuentas por cobrar afecta la liquidez de la empresa, generando ineficiencias en la gestión del flujo de caja y errores en los registros contables. Se plantearon dos alternativas de solución. Alternativa A consiste en la contratación de una empresa consultora especializada para la implementación del control interno en las cuentas por cobrar, asegurando una intervención profesional y la aplicación de mejores prácticas. Alternativa B propone el desarroll...

This paper analyses competition conditions in the natural gas market in Argentina since the early 90 when the sector was privatized. These reforms aimed to improve efficiency. In order to achieve this goal, assets where privatized, the market was deregulated and competition was promoted. This paper analyses the effects of these reforms on competition conditions in the natural gas market. Concentration indexes show a high degree of concentration both at the national level and at the different basins. Also concentration has not decreased since the privatization process was launched. Finally, this market also presents high sunk costs that create barriers to entry for the entrance of new competitors. Competition conditions are more consistent with the performance of an oligopoly market. The Competition Authority and the Sectorial Regulator should monitor this performance since this ...

Coastal wetlands adjacent to urban areas, such as the Pantanos de Villa in the city of Lima, Peru, are subject to constant changes in land use due to anthropogenic interaction. This has led to the reduction of dense vegetation areas, giving way to built-up areas. Therefore, this article addresses the issue of the physical changes experienced in urban areas adjacent to the wetland, such as the environmental management units, in this case the Zone of Protection of Outcrop and Surface Runoff (ZPAES), and the Zone of Landscape Protection of Edge (ZPB), as well as the Pantanos de Villa Wildlife Refuge (RVSPV), as a result of rapid urban expansion. Therefore, the objective of this research is to analyze the spatial and temporal evolution of the Pantanos de Villa environment and urbanization within the Environmental Management Units ZPB, ZPAES, and RVSPV. To achieve this, the Google Earth Engin...

Parkinson’s disease (PD) is a gradually worsening neurodegenerative disorder affecting the nervous system, marked by a slow progression and varied symptoms. It is the second most common neurodegenerative disease, affecting over six million people in the world. Its multifactorial etiology includes environmental, genomic, and epigenetic factors. Clinical symptoms consist of non-motor and motor symptoms, with motor symptoms being the classic presentation. Therapeutic approaches encompass pharmacological, non-pharmacological, and surgical interventions. Traditional pharmacological treatment consists of administering drugs (MAOIs, DA, and levodopa), while emerging evidence explores the potential of antidiabetic agents for neuroprotection and gene therapy for attenuating parkinsonian symptoms. Non-pharmacological treatments, such as exercise, a calcium-rich diet, and adequate vitamin D suppl...
