title: De novo heterozygous variants in EHMT2 genocopy Kleefstra syndrome via loss of G9a methyltransferase activity - Histone modifications mass spect

description: Histone modifications quantified by mass spectrometry dataset used in: De-novo heterozygous variants in EHMT2 genocopy Kleefstra syndrome via a loss of G9a methyltransferase activity. A. Hnizda, B. Martinez-Delgado et al.

 
description: Mass spectrometry was performed by Active Motif. Histones were acid extracted from a cell pellet containing 2.5x106 cells, derivatized via propionylation, digested with trypsin, newly formed N-termini were propionylated as previously described. Histones were extracted by incubating samples at room temperature for 1 hour in 0.2M sulfuric acid with intermittent vortexing. Histones were then precipitated by the addition of trichloroacetic acid (TCA) on ice, and recovered by centrifugation at 10,000 x g for 5 minutes at 4°C. The pellet was then washed once with 1mL cold acetone/0.1% HCl and twice with 100% acetone, and then air dried in a clean hood. The histones were propionylated by adding 1:3 v/v propionic anhydride/2-propanol and incrementally adding ammonium hydroxide to keep the pH around 8, and subsequently dried in a SpeedVac concentrator. The pellet was then resuspended in 100 mM ammonium bicarbonate and adjusted to pH 7-8 with ammonium hydroxide. The histones were then digested with trypsin, resuspended in 100mM ammonium bicarbonate overnight at 37°C, and dried in a SpeedVac concentrator. The pellet was resuspended in 100mM ammonium bicarbonate and propionylated a second time by adding 1:3 v/v propionic anhydride/2-propanol and incrementally adding ammonium hydroxide to keep the pH around 8, and subsequently dried in a SpeedVac concentrator. Histone peptides were resuspended in 50 µL of 0.1% TFA and 3 µl were injected with 3 technical replicates in a Thermo Scientific TSQ Quantum Ultra mass spectrometer coupled with an UltiMate 3000 Dionex nano-liquid chromatography system. The data was quantified using Skyline and represents the percent of each modification within the total pool of that amino acid residue. A total of 92 modification states were quantified, including unmodified ones.

title: Dual Enrollment, Institutional Characteristics, and the 2025 Carnegie Classifications for U.S. Higher Education Institutions (2023-2024)

description: This dataset provides an institutional-level analysis of dual enrollment programs at 2,118 Title IV-eligible colleges and universities across the United States. It was compiled to support policy research on the landscape of early college credit opportunities and their relationship with institutional mission, structure, and student outcome profiles.

A key feature of this dataset is the integration of dual enrollment activity with the newly released 2025 Carnegie Classifications, including the Basic, Social and Economic Mobility, and Research classifications. The dataset contains detailed dual enrollment counts by race, ethnicity, and gender, along with numerous institutional characteristics such as sector, urbanicity, and HBCU status.

It also includes several key derived variables created for analysis, most notably "Dual Enrollment Intensity," which measures the size of an institution's dual enrollment program relative to its full-time equivalent undergraduate population. This curated dataset is designed to facilitate research on which types of institutions are the primary providers of dual enrollment and how this form of engagement aligns with their broader mission and performance on access and earnings metrics.

The dataset was constructed on September 29, 2025, by merging data from three primary sources using the unique institutional identifier (UnitID):





Integrated Postsecondary Education Data System (IPEDS) 2024-2025 Collection Year:





Dual enrollment counts are from the 12-Month Enrollment (EFFY) survey component, reflecting the 2023-2024 academic year.




The denominator for the intensity metric (FTEUndergraduate24) is the 12-month full-time equivalent (FTE) unduplicated undergraduate count from the 12-Month Enrollment (E12) survey component.




Other institutional characteristics are also sourced from various IPEDS survey components.






2025 Carnegie Classifications of Institutions of Higher Education:





Sourced from the public data files provided by the American Council on Education (ACE). This includes the basicclass24, succaccessclass24, and researchclass24 variables.





The primary derived metric, dualenrollintensity, was calculated as: (Total Dual Enrollment Students / 12-Month Unduplicated FTE Undergraduate Enrollment)

Dichotomous variables for institutional control, level, urbanicity, and research activity were generated for regression analysis.

title: Literature Analysis: Comparative Law in Germany and the Global South

description: This dataset accompanies the article “Comparative Law and the Global South Gap: An Empirical Analysis of Comparative Legal Academia in Germany”. It contains five interrelated datasets generated through systematic literature analysis of academic scholarship on comparative law, legal transplants, and sustainable corporate law. The datasets are as follows: Legal Transplants Data (focusing on observed legal transplants in German literature), Comparative Literature Data (focusing on conducted comparisons within German comparative literature), Comparative Authors Data (referencing the Comparative Literature Data connecting it with biographical data on the authors of comparisons with the Global South), Sustainable Corporate Law Data (maps references to foreign legal systems and comparative reasoning in German-language debates on sustainable company law), SCL Scoring (referencing the Sustainable Corporate Law Data and providing a scoring matrix to quantify the engagement with different legal systems). Each dataset contains metadata and qualitative coding to facilitate further analysis. Together, they offer empirical insight into epistemic hierarchies and comparative engagement between Germany and the Global South in legal scholarship.

title: MAGIC_AND_SUPERSTITION_IN_THE_WORLDVIEW_OF_LATVIAN_PEASANTS_16TH18TH_CENTURIES

description: The project focuses on the ideas of Latvian peasants about the world around them and their place in it, which are explored through the analysis of magical rituals and superstitions widespread in this social group in the 16th - 18th centuries. Magic is rituals associated with belief in a person’s ability to supernaturally influence people, animals, natural phenomena, as well as imaginary spirits and gods. In turn, superstition is understood as belief in the miraculous, supernatural, belief in cause and effect, where a cause-and-effect relationship is not visible. The project examines the following issues: factors that influenced the formation of magical rituals and superstitions; belief in miracles; ideas about the earthly and otherworldly worlds; man in the earthly and otherworldly worlds; nature in superstitions and magic; magical rituals, and superstitions in everyday life of peasants; peasants in witch trials. The research is based on an interdisciplinary and phenomenological approach.
