title: Advancing Green Construction through Synchrotron Analysis of Calcined Clay Concrete

description: Concrete heavily relies on Portland cement, whose demand has surged, contributing 8% to global CO2 emissions. Integrating waste materials like calcined clay as supplementary cementitious materials offers a sustainable solution, diverting waste from landfills (waste clays from industrial by-products, mine tailing, and construction works). Calcined clay reduces environmental strain, conserves resources, and lowers production costs due to its lower energy requirements. Additionally, it enhances concrete performance, extending product lifespan and reducing the need for frequent replacements, thus conserving resources in the long term. This research project aims to optimize early-age strength in calcined clay concrete by studying reaction kinetics within the initial 72 hours (in 2-hour intervals) and after seven days. Synchrotron X-ray diffraction (XRD) has the ability, which standard laboratory equipment does not, to identify and quantify crystalline phases formed during these periods. These findings will inform mix proportioning and clay-type selection for enhanced early-age strength by elucidating crystalline phase formation. Micro and nano computed tomography (CT) techniques will characterize the pore structure development and distribution of calcined clay concrete and enable correlation of these findings with strength development. Pore sizes reduce with time (at nanoscale, beyond standard CT resolution) as they are filled with hydration products. The use of synchrotron techniques will enable this refinement in the pore structure to be observed. The investigation spans from 1 and 7 days and to later ages (28 , 90, 180 and 360 days), shedding light on how calcined clay influences pore structure and porosity changes, and how the reactant constituents quantified via XRD, affect the refinement of pore structure of concrete. This will be beneficial in forming a relationship between quantified XRD data(phases forming), the pore structure (from micro/nano CT), and the strength of concrete at different ages (to be measured independently in standard lab experiments in accordance with international standards).

title: HIFLD Open 4-digit HU (Subregion)

description: The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. It defines the areal extent of surface water drainage to a point except in coastal or lake front areas where there could be multiple outlets as stated by the "Federal Standards and Procedures for the National Watershed Boundary Dataset (WBD)" (https://pubs.usgs.gov/tm/11/a3/). Watershed boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. This dataset represents the hydrologic unit boundaries to the 12-digit for the entire United States. Some areas may also include additional subdivisions representing the 14- and 16-digit hydrologic unit (HU). At a minimum, the HUs are delineated at 1:24,000-scale in the conterminous United States, 1:25,000-scale in Hawaii, Pacific basin and the Caribbean, and 1:63,360-scale in Alaska, meeting the National Map Accuracy Standards (NMAS). Higher resolution boundaries were developed where partners and data existed and were incorporated back into the WBD. WBD data are delivered as a dataset of polygons and corresponding lines that define the boundary of the polygon. WBD polygon attributes include hydrologic unit codes (HUC), size (in the form of acres and square kilometers), name, downstream hydrologic unit code, type of watershed, non-contributing areas, and flow modifications. The HUC describes where the unit is in the country and the level of the unit. WBD line attributes contain the highest level of hydrologic unit for each boundary, line source information and flow modifications.

title: THE MIDDLE EAST DEMOCRACY TRAP: Why Electoral Competition Undermines Property Rights in Islamic Countries

description: This dataset accompanies the research paper "The Middle East Democracy Trap: Why Electoral Competition Undermines Property Rights in Islamic Countries" which examines how electoral democracy affects property rights protection across 93 developing countries from 2007-2023.

Key Finding: Electoral democracy's effect on property rights is conditionally negative, depending on sectarian fragmentation and institutional capacity. In Islamic-majority countries, electoral democracy significantly undermines property rights (β=-4.73, p<0.01), while in non-Islamic developing countries, democracy shows positive or neutral effects (β=+1.82, n.s.). The interaction between electoral democracy and Islamic context is highly significant (β=-6.55, p=0.002).

Dataset Contents:



Cross-sectional data (2023) for 93 developing countries with complete variables

Panel data (2007-2023) with 1,526 country-year observations from 102 countries

Regression output tables (cross-sectional, panel, lagged variables, interaction models)

Visualization of regional heterogeneity in democracy-property rights relationships

Original data sources: International Property Rights Index (IPRI 2007-2025) and Varieties of Democracy (V-Dem v15)


Methodology: The analysis employs OLS regression with robust standard errors, country fixed effects panel models, lagged independent variables for causal identification, and difference-in-differences estimation using the Arab Spring as a natural experiment. Regional subsamples demonstrate the pattern is specific to MENA/Islamic countries, not universal.

Policy Implications: Results suggest democracy promotion requires institutional sequencing—building rule of law, judicial capacity, and civil society before competitive elections, particularly in sectarian contexts. Rapid democratization without institutional foundations can worsen property rights protection.

Replication: All analysis code (Python/Jupyter notebook), raw data files, and regression outputs are included for full reproducibility.
