Studying Public Policy through Immigration Policy: Advances in Theory and Measurement

This essay provides a critical review of the field of immigration policy studies from the perspective of measurement and modeling. It serves to contextualize and broaden the views presented in the special issue. As such, we combine insights from American and comparative politics, pinpoint key limitations and challenges in the field, and identify areas of strength within each subfield which could inform theory and measurement development for the other. Ultimately, the concerns about conceptualization, definition, and measurement that we identify and discuss herein, do not apply only to immigration policy studies but to policy studies writ large.     

'The purity of the blood': Poncet de la Grave,pronatalism and empire

This article will analyze key publications of Guillaume Poncet de la Grave (1725-1803), formerly the monarchy’s representative to the Admiralty Court, who worked during the Ancien Régime to restrict immigration to France, particularly that of people of color. He was also a passionate advocate for French imperial expansion. After the Revolution, in his political tract Réflections on the Unmarried, he expressed his anxiety over a declining French birthrate and a desire to have the state monitor marriage, sexuality, and reproduction in order to increase legitimate births. In this work he identified threats to what he referred to as ‘the purity of the blood’ within and without France, and proposed to the Republic legislation designed to eliminate them. Poncet de la Grave’s career has been largely neglected but his former position merits a closer look at his political writing, which expressed significant, constant objectives that demonstrate thematic continuity over a tumultuous time. French fears of depopulation and national ‘degeneration’ were still strong at the turn of the century, and remain of great interest to historians eager to understand how they were discussed in the context of great historical change.     

High-throughput mass spectrometric analysis of 1400-year-old mycolic acids as biomarkers for ancient tuberculosis infection

The cell wall of mycobacteria includes an unusual outer membrane of extremely low permeability. This cell envelope consists of a characteristic cell wall skeleton, a mycoloyl arabinogalactan peptidoglycan complex, and related hydrophobic components that contribute to the cell surface properties. In this study 1400-year-old mycolic acids as unique tuberculosis biomarkers have been extracted and identified for the first time by using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI TOF MS) and Fourier transform infrared spectroscopy (FT-IR). The data suggest that the MALDI TOF MS has potential as a rapid and reproducible technique for the detection and identification of ancient mycobacterial infections.     

The Choir of Auxerre Cathedral and the Question of a Burgundian Gothic Architecture

Despite criticisms, the classification of the choir of Auxerre Cathedral as Burgundian persists in recent literature. Yet the cathedral’s choir, begun c. 1215, demonstrates the problematic nature of the existing regional categories for French medieval architecture. Based on the 19th-century idea of progress, the conceptual model that conceives Gothic France as consisting of ‘centre and periphery’ and notions such as regional styles or period styles are deeply at odds with medieval concepts of innovation as inclusive of tradition, as evidenced in the biography of Bishop William of Auxerre (1207–20). Indeed, 20th-century studies in support of the classification are contradicted by recent archaeological findings, and neither the historical evidence nor the architectural evidence support a Burgundian label for the choir. The architecture’s distinctly trans-regional character with a mixture of both traditional and up-to-date architectural elements as well as the fact that patronal identities were strongly based on local affiliations and not attached to the duchy of Burgundy, invite a profound reconsideration not only of the position of the choir in the architectural landscape of the early 13th century but also of Gothic architecture of north-eastern France in more general terms.
