This Special Issue of Genealogy examines the use of evidence, documentation, and methodology in family history and genealogical studies, and welcomes case studies that examine how to document individuals and relationships. A critical component of scholarly research focusing on the study of particular individuals or groups entails correctly identifying those individuals Historians, genealogists, historical demographers, and scholars in other disciplines sometimes undertake this sort of analysis. Often, research is uncomplicated if the research subject remained in a particular geographical area, or left a clear evidentiary trail, but what happens when historical documents do not clearly identify the research subject? Utilizing a case study approach, this essay employs four different research methods—the chronological study, family reconstitution, community study techniques, and the one-name study—to identify an individual whose correct historical identification was problematic. As such, it establishes a research strategy that can be employed in similar situations. Full article

Abstract

The COVID-19 pandemic caused a drastic reduction in air traffic passengers, especially during the period when the EU countries introduced a lockdown. Even after the relaunch of airline operators, passenger traffic did not return to the pre-pandemic trend. The aim of the study was to estimate the difference between the demand that was observed during the pandemic, and the demand that was forecast based on the pre-pandemic trend. The calculations were made for airports in selected EU countries. The first method was seasonality indicators, using quarterly data for 2015–2021. In the multiplicative model of seasonal fluctuations, the method of determining the seasonality indicators was used, based on the quotient of empirical values and the value of the trend. The one-name period trend method was used in the next step, then Fourier spectral analysis was applied. In the context of forecasts for the individual quarters of 2020 and 2021, all models indicate a further growing trend in the demand for passenger transport, which could have been observed if the COVID-19 pandemic had not occurred. As a result of the pandemic, the number of passengers handled at airports has significantly decreased. In the third quarter of 2021, freight growth was already noticeable, with the exception of Netherland, where a marked decline was recorded. Full article
