Este texto, derivado de una ponencia en una conferencia, es un informe preliminar de un proyecto a larga escala para trazar las transformaciones en las estructuras de las redes de la élite florentina a lo largo de dos siglos. En este artículo me limito únicamente a la descripción de tendencias anteriores, desconocidas en modelos amplios, de los matrimonios cruzados florentinos. Los lectores informados verán inmediatamente que dichas tendencias tienen implicaciones importantes para los debates en la historiografía florentina (que desarrollaré más adelante). En último término, estoy interesado en las implicaciones políticas de las tendencias aquí descritas. Pero por ahora no entro en una interpretación, explicación o argumentación. Trataré únicamente de mostrar hechos nuevos. ; This conference paper is an interim report from a large-scale project to trace transformations in Florentine elite network structures over two centuries. In this paper, I confine myself solely to a description of previously unknown trends in broad patterns of Florentine inter-marriage. Knowledgeable readers will immediately see that these trends have important implications for debates in Florentine historiography (which I will develop in the future). Ultimately, I am primarily interested in the political implications of the trends I herein describe. But for now I do not engage in interpretation, explanation, or argumentation. I intend simply to lay out some new facts.

Two bounded rationality theories of federal budgetary decision making are operationalized and tested within a stochastic process framework. Empirical analyses of Eisenhower, Kennedy and Johnson domestic budget data, compiled from internal Office of Management and Budget planning documents, support the theory of serial judgment over the theory of incrementalism proposed by Davis, Dempster and Wildavsky. The new theory highlights both the structure of ordered search through a limited number of discrete alternatives and the importance of informal judgmental evaluations. Serial judgment theory predicts not only that most programs most of the time will receive allocations which are only marginally different from the historical base, but also that occasional radical and even "catastrophic" changes are the normal result of routine federal budgetary decision making. The methodological limitations of linear regression techniques in explanatory budgetary research are also discussed.

The social sciences have sophisticated models of choice and equilibrium but little understanding of the emergence of novelty. Where do new alternatives, new organizational forms, and new types of people come from? Combining biochemical insights about the origin of life with innovative and historically oriented social network analyses, John Padgett and Walter Powell develop a theory about the emergence of organizational, market, and biographical novelty from the coevolution of multiple social networks. They demonstrate that novelty arises from spillovers across intertwined networks in different domains. In the short run actors make relations, but in the long run relations make actors. This theory of novelty emerging from intersecting production and biographical flows is developed through formal deductive modeling and through a wide range of original historical case studies. Padgett and Powell build on the biochemical concept of autocatalysis--the chemical definition of life--and then extend this autocatalytic reasoning to social processes of production and communication. Padgett and Powell, along with other colleagues, analyze a very wide range of cases of emergence. They look at the emergence of organizational novelty in early capitalism and state formation; they examine the transformation of communism; and they analyze with detailed network data contemporary science-based capitalism: the biotechnology industry, regional high-tech clusters, and the open source community.
