    Accurate modeling of confounding variation in eQTL studies leads to a great increase in power to detect trans-regulatory effects

    Get PDF
    Expression quantitative trait loci (eQTL) studies are an integral tool to investigate the genetic component of gene expression variation. A major challenge in the analysis of such studies are hidden confounding factors, such as unobserved covariates or unknown environmental influences. These factors can induce a pronounced artifactual correlation structure in the expression profiles, which may create spurious false associations or mask real genetic association signals. 

Here, we report PANAMA (Probabilistic ANAlysis of genoMic dAta), a novel probabilistic model to account for confounding factors within an
eQTL analysis. In contrast to previous methods, PANAMA learns hidden factors jointly with the effect of prominent genetic regulators. As a result, PANAMA can more accurately distinguish between true genetic association signals and confounding variation. 

We applied our model and compared it to existing methods on a variety of datasets and biological systems. PANAMA consistently performs better than alternative methods, and finds in particular substantially more trans regulators. Importantly, PANAMA not only identified a greater number of associations, but also yields hits that are biologically more plausible and can be better reproduced between independent studies

    The paper reviews the salient features of officially dollarized economies (with particular reference to Panama) and discusses costs and benefits of official dollarization. Also, the paper reviews existing and some potential seigniorage sharing arrangements and discusses conditions that are conducive to official dollarization, especially in Latin America.dollarization monetary unions seigniorage Panama Latin America

    Do Exchange Rate Regimes Matter For Inflation And Exchange Rate Dynamics? The Case Of Central America.

    This paper makes an empirical contribution to the discussion on the optimal exchange rate regime. Using as astudy case the experience of the Central American countries, we compare the dynamics of the Real Exchange Rate (RER) and inflation persistence between dollarized economies and countries with some degree of exchange rate flexibility. Our results show that the two dollarized countries in the region, El Salvador and Panama, are quite different in terms of RER and inflation dynamics. While in El Salvador the RER spends more time away from the equilibrium level than the non-dollarized countries in the region, the opposite is true for Panama. We also find that inflation persistence in El Salvador is similar to that of the other countries, but smaller in Panama. This leads us to the conclusion that some degree of exchange rate flexibility helps countries to have a RER more aligned with its fundamentals. Nevertheless, a long-lived, highly credible dollarized economy, like Panama, can reduce inflation persistence to such an extent that RER misalignments are actually less frequent than in countries with more flexible exchange rate regimes.

    The State of the Upper Bay of Panama Wetlands: Ecological Significance, Environmental Policy, Urbanization, and Social Justice

    I conducted this research while studying abroad with SIT Panama: Tropical Ecology, Marine Ecosystems, and Biodiversity Conservation. This is a multidisciplinary investigation of the Upper Bay of Panama wetlands, a 49,000 hectare region east of Panama City that features mangrove, intertidal mudflat, and grassland habitat internationally recognized as a stopover site for two million shorebirds every migration season. However, with economic pressure to increase urban development in the area, this land’s protected status under the Ramsar convention was suspended for a year in April 2012. By compiling scientific studies, news articles, photographs, and interviews with local conservationists and community members, this project describes the ecological, political, and social conditions surrounding this area today. I found that this ecosystem contains plentiful nutrients from both seasonal upwelling and mangrove detritus, supporting a thriving aquatic food chain, including major fisheries, but also experiences garbage, agrochemical, and heavy metal inputs from human activities. Because of reduced infiltration caused by new developments, plus ongoing construction, much of the eastern Panama City district of Juan Díaz is now regularly subject to flooding too severe for its current drainage system to control, for which I provided photographic evidence, and receives little compensation. By law, though, Panama’s government is obligated to protect these people’s right to live in a healthy environment. Strategies for ecosystem management should be planned for the long-term and include economic incentives, citizen involvement, and government support. There is also a need to promote education of wetlands ecosystem benefits and the repercussions of their removal

    Some aspects of upwelling in the Gulf of Panama

    Get PDF
    ENGLISH: Strong coastal upwelling occurs in the Gulf of Panama regularly each year during the season, from about January through April, when strong northerly winds are blowing offshore. Because of the evident importance of upwelling to the ecology of the Gulf of Panama, we commenced in the fall of 1954 a study of various physical, chemical, and biological phenomena associated therewith. Observations were taken at bi-weekly intervals at a fixed location in the Gulf (approximately 10 miles SE of Taboga Island) to supplement the serial observations of sea level, sea temperature, and winds that have been gathered for many years by the Panama Canal Company. SPANISH: Cado año, en la estación de enero a abril, cuando los vientos del norte soplan vigorosamente frente a la costa, ocurre en el Golfo de Panamá un fuerte afloramiento costanero. Se cree que este afloramiento periódico en el Golfo de Panamá es responsable de la alta productividad biológica que sostiene considerables cantidades de organismos de importancia comercial. Esta región, por ejemplo, es una fuente importante de la especie Cetengraulis mysticetus) pez de carnada para el atún, (Alverson y Shimada, 1957) y mantiene una considerable pesca de camarones llamados langostinos (Burkenroad, Obarrio y Mendoza,1955).
