Balancing Precision and Retention in Experimental Design
In experimental social science, precise treatment effect estimation is of utmost importance, and researchers can make design choices to increase precision. Specifically, block-randomized and pre-post designs are promoted as effective means to increase precision. However, implementing these designs requires pre-treatment covariates, and collecting this information may decrease sample sizes, which in and of itself harms precision. Therefore, despit…
Ignoring Women’s Performance
How does a politician’s gender shape citizen responses to performance in office? Much of the existing literature suggests that voters hold higher expectations of women politicians and are more likely to punish them for malfeasance. An alternative perspective suggests that voters view men politicians as more agentic and are, therefore, more responsive to their performance, whether good or bad. Using an online survey experiment in Argentina, we ran…
Exploring stakeholders perspectives on TB contact investigation in Cali, Colombia
Introduction: Contact investigation is a proven intervention for tuberculosis (TB) case finding and prevention. Although widely endorsed by national public health authorities and the World Health Organization, many countries struggle to implement it effectively. The objective of the study is to describe and characterize the barriers and facilitators of TB contact investigation in Cali, Colombia from the perspective and experience of the key stake…
Assessing the Validity of Prevalence Estimates in Double List Experiments
Social scientists use list experiments in surveys to estimate the prevalence of sensitive attitudes and behaviors in a population of interest. However, the cumulative evidence suggests that the list experiment estimator is underpowered to capture the extent of sensitivity bias in common applications. The literature suggests double list experiments (DLEs) as an alternative to improve along the bias-variance frontier. This variant of the research d…
Identification of Nontuberculous Mycobacteria in Drinking Water in Cali, Colombia
Nontuberculous mycobacteria (NTM) are ubiquitous microorganisms naturally resistant to antibiotics and disinfectants that can colonize drinking water supply systems. Information regarding the spread of NTM in specifically South America and Colombia is limited. We aimed to identify and characterize NTM present in tap water samples from Cali, Colombia. Drinking water samples and faucet biofilm swabs were collected in 18 places, including the city's…
Light in the midst of chaos
Assessment of anthropogenic threats to Chilean Mediterranean freshwater ecosystems
A new multi-proxy record of environmental change over the last 1000 years on Chiloé Island
Knowledge of past environmental and climatic conditions of lake ecosystems on Chiloé Island on a millennial scale is limited. Hence, this study fills a gap in our understanding of this part of southern Chile. The aim of this study was to reconstruct the environmental and climatic history of the last 1000 years of Lake Pastahué through a multi-proxy sediment core analysis. The 1-m-long core was subsampled every centimeter for the organic matter, m…
