Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Lord of the lemons: Origin and dynamics of state capacity
Get PDFTo better understand the role of taxation in the emergence of states, this article presents an incomplete contract model of an agricultural society in which information asymmetries cause inefficient taxation, and hence outmigration, uprisings, and rent-seeking, but also urbanization. We propose a geographic index of information costs, observability, to test our model. Our case study is the Holy Roman Empire, which had a relatively homogeneous institutional framework, state of technology, culture, and ethnic composition across hundreds of observed states, for over 500 years. We find a robust link between observability and states' tax capacity, their size, and their survival
You Reap What You Know: Observability of Soil Quality, and Political Fragmentation
No full textWe provide a theoretical model linking limits to the observability of soil quality to state rulers' ability to tax agricultural output, which leads to a higher political fragmentation. We introduce a spatial measure to quantify state planners' observability in an agricultural society. The model is applied to spatial variation in the 1378 Holy Roman Empire, the area with the highest political fragmentation in European history. We find that differences in the observability of agricultural output explain the size and capacity of states as well as the emergence and longevity of city states. Grid cells with higher observability of agricultural output intersect with a significantly lower number of territories within them. Our results highlight the role of agriculture and geography, for size, political, and economic organization of states. This sheds light on early, though persistent, determinants of industrial development within Germany, and also within Central Europe
The fetters of inheritance? Equal partition and regional economic development
No full textHow can agricultural inheritance traditions affect structural change and economic development in rural areas? The most prominent historical traditions are primogeniture, where the oldest son inherits the whole farm, and equal partition, where land is split and each heir inherits an equal share. In this paper, we provide a theoretical model that links these inheritance traditions to the local allocation of labor and capital and to municipal development. First, we show that among contemporary municipalities in West Germany, equal partition is significantly related to measures of economic development. Second, we conduct OLS and fuzzy spatial RDD estimates for Baden-Württemberg in the 1950s and today. We find that inheritance rules caused, in line with our theoretical predictions, higher incomes, population densities, and industrialization levels in areas with equal partition. Results suggest that more than a third of the overall inter-regional difference in average per capita income in present-day Baden-Württemberg, or 597 Euro, can be explained by equal partition

How England Unified Germany: Geography and the Rise of Prussia After 1815
No full textWe analyze the formation oft he German Zollverein as an example how geography can shape institutional change. We show how the redrawing of the European map at the Congress of Vienna-notably Prussia's control over the Rhineland and Westphalia-affected the incentives for policymakers to cooperate. The new borders were not endogenous. They were at odds with the strategy of Prussia, but followed from Britain's intervention at Vienna regarding the Polish-Saxon question. For many small German states, the resulting borders changed the trade-off between the benefits from cooperation with Prussia and the costs of losing political control. Based on GIS data on Central Europe for 1818-1854 we estimate a simple model of the incentives to join an existing customs union. The model can explain the sequence of states joining the Prussian Zollverein extremely well. Moreover we run a counterfactual exercise: if Prussia would have succeeded with her strategy to gain the entire Kingdom of Saxony instead of the western provinces, the Zollverein would not have formed. We conclude that geography can shape institutional change. To put it different, as collateral damage to her intervention at Vienna,"'Britain unified Germany"'
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
