The identification of quantitative fertility indicators for evaluating the sustainability of cropping and farming systems has become a major issue. This question has been extensively studied by the German agronomist Albrecht Daniel Thaer at the beginning of the 19h century. In this paper Thaer's work is set in its historical background, from the end of the 16th century (Palissy, 1580) to the middle of the 19th century (Liebig, 1840). Then the paper focuses on Thaer's quantitative and complex fertility scale (expressed in fertility degrees), which was based on soil properties, on the requirement of nutrients by plants, and on the cropping system (including crop rotation). Thaer expressed soil fertility and economic results as a function of rye production in scheffel of rye per journal (ca. 200 kg per hectare). He also proposed a scale to describe the intrinsic fertility of soil. Thaer used this approach to assess the effect of major German cropping systems on soil fertility. He applied it to eight theoretical systems and nine existing systems in a true modeling approach. Thaer completed the fertility evaluation for the nine existing systems with a detailed economical analysis commenting the limits and potentialities of each system. Thaer's approach was used with success during half a century as it combined numerous empirical findings on soils and fertilization with organic substances in a sophisticated model. Unfortunately and despite effective practical applications, the scientific foundations of Thaer's Humus Theory proved definitively false as soon as 1840 when Sprengel and Liebig published on mineral nutrition of plants. Thaer's work deserves to be rediscovered since it approaches the modern issue of the sustainability of cropping and farming systems.

Intra-Writer Variation in Historical Sociolinguistics
2023; Vol. 00005
Intra-individual variation is an emerging research field in linguistics with a rapidly growing number of studies. In historical sociolinguistics, this trend has been slow, as it is still largely dominated by the macroscopic approaches of earlier sociolinguistics. Microscopic studies focusing on intra-individual variation in writing, i.e. intra-writer variation, however, are able to reveal how writers functionalize social or text-type variation for reasons such as audience design or persona creation. They may also provide insights into how ongoing changes were perceived by speakers and writers. In general, micro-approaches are able to uncover a wide array of possible factors influencing variation, which may not always carry sociolinguistic functions. This volume comprises twenty-two research articles on a wide range of languages and periods, all closely connected by their focus on intra-writer variation in historical texts and by their use of empirical and corpus-based approaches. The studies demonstrate that the challenges that historical material have for research on intra-individual variation can certainly be met and that the insights gleaned from analysing variation in individual writers are considerable.

Exploring the Interior : Essays on Literary and Cultural History
2018
In this fascinating collection of essays Harvard Emeritus Professor Karl S. Guthke examines the ways in which, for European scholars and writers of the eighteenth and early nineteenth century, world-wide geographical exploration led to an exploration of the self. Guthke explains how in the age of Enlightenment and beyond intellectual developments were fuelled by excitement about what Ulrich Im Hof called'the grand opening-up of the wide world”, especially of the interior of the non-European continents. This outward turn was complemented by a fascination with'the world within” as anthropology and ethnology focused on the humanity of the indigenous populations of far-away lands – an interest in human nature that suggested a way for Europeans to understand themselves, encapsulated in Gauguin's Tahitian rumination'What are we?” The essays in the first half of the book discuss first- or second-hand, physical or mental encounters with the exotic lands and populations beyond the supposed cradle of civilisation. The works of literature and documents of cultural life featured in these essays bear testimony to the crossing not only of geographical, ethnological, and cultural borders but also of borders of a variety of intellectual activities and interests. The second section examines the growing interest in astronomy and the engagement with imagined worlds in the universe, again with a view to understanding homo sapiens, as compared now to the extra-terrestrials that were confidently assumed to exist. The final group of essays focuses on the exploration of the landscape of what was called'the universe within”; featuring, among a variety of other texts, Schiller's plays The Maid of Orleans and William Tell, these essays observe and analyse what Erich Heller termed'The Artist's Journey into the Interior.” This collection, which travels from the interior of continents to the interior of the mind, is itself a set of explorations that revel in the discovery of what was half-hidden in language. Written by a scholar of international repute, it is eye-opening reading for all those with an interest in the literary and cultural history of (and since) the Enlightenment.

Ideen, Methoden und Entwicklungen der Geschichte des ökonomischen Denkens. : Studien zur Entwicklung der ökonomischen Theorie XXII.
2009; Vol. 00115
Der Band enthält die Referate der 21. Tagung des Dogmenhistorischen Ausschusses: Dieter Schneider plädiert für eine taxonomische Neugliederung der Geschichte des ökonomischen Denkens und für eine Neubewertung der Klassischen Politischen Ökonomie und ihrer Vorläufer. Karl-Heinz Schmidt arbeitet Merkmale und Entwicklungstendenzen in der jüngeren ökonomischen Ideengeschichtsschreibung heraus. Bertram Schefold erläutert die leitenden Gedanken und Probleme bei der Zusammenstellung der hundertbändigen Faksimile-Edition'Klassiker des ökonomischen Denkens'und stellt Überlegungen zur zukünftigen Entwicklung der Theoriegeschichte an. Heinz Rieter legt eine mehr als 850 Titel umfassende und mit dem 17. Jahrhundert beginnende Dokumentation der Autobiographien von Ökonomen aus dem deutschen und dem angelsächsischen Sprachraum vor. Gottfried Eisermann analysiert Leben und Werk des'Romantikers'Adam Müller (1779 - 1829), und Mark Perlman liefert am Beispiel der Ökonomen Kuznets, Schumpeter und Burns eine auf persönliche Erinnerungen zurückgreifende Fallstudie zum Thema'Meinungsunterschiede und Kontroversen zwischen Ökonomen'.

A brief and comprehensive history of the development and use of feed analysis: A review.
Open Agriculture; Jan2022, Vol. 7 Issue 1, p837-846, 10p
Currently, there are no general reviews that focus on feed analysis and its development from early to modern use. An objective of this review was to create a brief chronology of people, discoveries, and activities that were part of the development of modern feed analysis. Peer-reviewed, extension, and trade literature were used as resources in this review. Conference and symposia proceedings were also referenced. Some textbooks and PhD dissertations were cited. Finally, historic agricultural and other scientific literature dating from 1725 to 1936 were all used as sources. In modern society, feed analysis is more widely used than ever before in history, and interest in and utilization of feed analysis steadily increases. The history of feed analysis is not a simple chronological construct, since feed analysis has developed in conjunction with advancements and discoveries in chemistry, nutrition, and agricultural sciences. Using different systems of analysis, the evaluation of feeds has been practiced for millennia. Feed analysis, its categories, systems, methods, and applications are topics of universal interest among extension, education, and agricultural professionals. This review of people, practices, and events leading to the development of feed analyses can be a useful resource for anyone who wants to convey unique information about feed analysis and its history.

''An Image of Science'': Cameralism, Statistics, and the Visual Language of Natural History in the Nineteenth Century.
Historical Studies in the Natural Sciences; Feb2018, Vol. 48 Issue 1, p56-109, 54p
This paper traces the emergence of a new visual language for statistical paleontology in the early nineteenth century as part of a broader project to uncover a deep genealogy of modern practices in data visualization. In the first decades of the nineteenth century, natural historians had amassed large quantities of taxonomic data, but lacked quantitative and visual methods to produce and communicate knowledge derived from their data collections. As our ''main witness'' (in Ian Hacking's sense), we call on the German paleontologist H. G. Bronn--one of the earliest proponents of a ''data-driven'' approach to statistical natural history--to highlight two unexpected sources of a transformative visual idiom introduced at the time: so-called spindle diagrams representing historical patterns in taxonomic diversity. The first source--which informed Bronn's general statistical approach to fossil data--was the bureaucratic science of cameralism, in which Bronn was steeped as a student and professor at the University of Heidelberg. The second was an earlier tradition of historical visualization popularized by Joseph Priestley and others, which represented time--or the ''timeline''--as measured graphical space on the horizontal axis of a chart. In combining the tabular statistical approach of Heidelberg cameralism and the historical timeline, Bronn contributed to the emergence of a powerful new visual language for producing and communicating aggregative statistical generalizations.

The Intellectual Origins of Modern Economic Growth.
Journal of Economic History; Jun2005, Vol. 65 Issue 2, p285-351, 67p
The intellectual origins of the Industrial Revolution are traced back to the Baconian program of the seventeenth century, which aimed at expanding the set of useful knowledge and applying natural philosophy to solve technological problems and bring about economic growth. The eighteenth-century Enlightenment in the West carried out this program through a series of institutional developments that both increased the amount of knowledge and its accessibility to those who could make best use of it. Without the Enlightenment, therefore, an Industrial Revolution could not have transformed itself into the sustained economic growth starting in the early nineteenth century. [ABSTRACT FROM AUTHOR]
