title: Holostic microplastics assesment in small urban lake (Velnezers, Latvia)

description: The data explores the presence, seasonal variations, historical accumulation and deposition rates of microplastics (MPs) in an urban lake within the Baltic region of Northern Europe. The dataset includes detailed information on MP concentrations in surface water, sedimentation rates, and the distribution of MPs within lake sediments. 
Key findings from the dataset include: Surface water MP concentrations were highest in summer (5.71 particles/m³) and decreased during winter (0.75 particles/m³), indicating seasonal variations; The MP deposition rate was calculated at 9.47 particles/cm²/year (or 4.31 μg/cm²/year); The sediment core analysis revealed MPs in layers older than 1950, predating the mass production of plastics; The predominant polymer types were polyethylene, polystyrene, and polypropylene, with fibres being more abundant in surface water and fragments in sediment layers.
The data provides a comprehensive snapshot of MPs in an urban lake, from seasonal fluctuations in surface water to long-term deposition patterns in sediment cores. Researchers can use this dataset to explore the dynamics of MP pollution in freshwater ecosystems, the impact of urbanisation on MP concentrations, and the relationship between seasonal variation and MP presence. Additionally, the data can be used to refine monitoring methods for MPs, particularly in urban lakes, where rapid, cost-effective approaches are crucial for ongoing surveillance.
The data was collected using well-established MP research methods:
Manta trawling for surface water sampling to measure MP concentrations, sediment trapping to assess MP sedimentation rates over one year, sediment coring to examine MP distribution in dated sediment archives. MP particles were identified and characterised using Attenuated Total Reflection (ATR) and micro-Fourier Transform Infrared (FTIR) spectroscopy. Sediment core chronology was determined using 210Pb dating and the Bayesian Plum model, which revealed sediment layers corresponding to periods before large-scale plastic production.
This dataset is valuable for researchers studying MP pollution in freshwater environments, particularly in urban settings. It can be used to establish baselines for future monitoring efforts and to develop more effective, resource-efficient methods for MP surveillance.

title: Advancing neonatal jaundice screening with mHealth: a mixed-methods randomized controlled feasibility study in a resource-limited setting in Mexico

description: This study evaluates the feasibility of Picterus JP in real-world conditions, in a resource limited setting in Oaxaca, Mexico by employing a mixed-methods approach including an RCT with both qualitative and quantitative assessments of the implementation process. The control group received standard jaundice screening and the intervention group was screened with Picterus JP plus the standard screening. Feasibility outcomes, including recruitment capability, device practicality, and fidelity to the study protocol were assessed.

Results:  the intervention group showed a statistically significant higher proportion of newborns who screened positive, were successfully referred to ER  (both p<0.001) and a higher proportion of newborn requiring  and receiving treatment (p<0.05) compared to the control group. There was a high recruitment rate (86%), low failure rate of the device (2.2%) and high adherence to the protocol.

title: Data and Code for: Declining Wage Inequality in Developing Countries: The Case of Brazil

description: This is the replication package for the paper Declining Wage Inequality in Developing Countries: The Case of Brazil. It includes data and codes necessary for replication.<br><br><b>Paper abstract</b>: Despite rising inequality in rich countries, many developing economies have experienced a decline in inequality in recent decades. Brazil is a notable example. From 1995 to 2015, its Gini index decreased from 58 to 48 points. An extensive body of research has investigated a diverse set of explanations for this reduction. This article reviews this literature, using Brazil as a privileged case study to understand the broader phenomenon of inequality decline in many parts of the developing world. We present stylized facts about inequality during this period, focusing on the results of decomposition methods. We then examine research that employs quasi-experiments and structural models to assess mechanisms related to labor supply and demand, trade, technological changes, and institutional factors such as the minimum wage and race and gender discrimination. We end by discussing some unanswered questions.
