title: Census Linking Project: 1850-1860 Crosswalk

description: This crosswalk consists of individuals matched between the 1850 and 1860 complete-count US Censuses. Within the crosswalk, users have the option to select the linking method with which these matches were created. This version of the crosswalk contains links made by the ABE-exact (conservative and standard) method, the ABE-NYSIIS (conservative and standard) method, ABE-EI exact (conservative and standard) method, and the ABE-EI NYSIIS (conservative and standard) method, with variants in which race is used as a matching variable. For any chosen method, users can merge into this crosswalk a wide set of individual- and household-level variables provided publicly by IPUMS, thereby creating a historical longitudinal dataset for analysis.

title: Replication Data for: Juon, Andreas (2025): Ethnic accommodation and the backlash from dominant groups. Journal of Conflict Resolution (2025).

description: This collection includes all data and the R script to replicate all figures and tables included in the main article text and online appendix. Abstract: When does the accommodation of subordinate ethnic groups generate a backlash from the politically dominant group? I argue that power-sharing, regional autonomy, and multiculturalism lend themselves to the articulation of grievances and fears among members of dominant groups, especially if they explicitly recognize subordinate groups' collective identities. In turn, nationalist parties can exploit such sentiment to organize protests, incite violence, and increase their electoral prospects. To test these arguments, I combine new monthly data on ethnic accommodation in 125 multi-ethnic electoral regimes between 1990 and 2018 with information on dominant group mobilization in anti-government protests and communal violence. I find systematic increases in dominant group mobilization around times when group-based accommodation is first introduced or expanded. These results enhance our understanding of mass mobilization by dominant ethnic groups. Moreover, they point to concrete proposals to reap the benefits of ethnic accommodation while avoiding a potentially destabilizing backlash against it.

title: Supplementary Material for: Determining the threshold concentration of birch pollen for inducing allergic symptoms using an allergen challenge chamber

description: Background: To determine threshold concentrations of pollen inducing symptoms in seasonal allergic rhinitis patients has been a challenge for decades. Allergen challenge chambers (ACC) allow a controlled, reproducible experimental design to address this problem. Hitherto, ACCs were only run with high pollen concentrations. 
Methods: The Fraunhofer ACC was technically modified to deploy very low pollen concentrations. Then, adults with birch pollen-induced allergic rhinitis were challenged with varying birch pollen concentrations using a patient-blinded, sham challenge-controlled, part-randomized, titrate-to-effect clinical study setting. Mean increase in Total Nasal Symptom Score (TNSS) ≥0.55 compared to sham challenge was regarded as minimal clinically important difference (MCID). Further endpoints were nasal secretion weight, exhaled nitric oxide (FeNO) and inflammatory cells from nasal lavage. 
Results: 15 participants with mild to moderate allergic rhinitis participated in the experimental study part (mean age 45 years [22 – 64]; 7 females). Mean TNSS was: 1.08 at 0 pollen/m3; 1.05 at 10 pollen/m3; 1.2 at 50 pollen/m3; 1.74 at 100 pollen/m3; 1.61 at 200 pollen/m3; 2.79 at 1,000 pollen/m3. MCID of TNSS was observed at 100, 200, and 1,000 pollen/m3. More than half of the study population showed a lack of response at 10, 50, and 200 pollen/m3. Nasal secretion increased slightly with concentration. No clinically meaningful results could be derived from FeNO and inflammatory cells.
Conclusions: The applied technical modification of the Fraunhofer ACC produced stable, low pollen concentrations. Based on mean TNSS data, the threshold concentration for inducing symptoms with birch pollen was 50-100 pollen/m3.
