Unlike static documents, version-controlled documents are edited by one or more authors over a certain period of time. Examples include large scale computer code, papers authored by a team of scientists, and online discussion boards. Such collaborative revision process makes traditional document modeling and visualization techniques inappropriate. In this paper we propose a new visualization te...

This paper makes some preliminary steps towards a dynamic theory of consumer choices, restricted to the case of repeated small decisions. We assume that the consumer chooses among products, rather than among bundles, and that she bases her decision on a cumulative satisfaction index. Such a consumer is not necessarily "optimizing" and may be "satisficing" in the sense of Simon (1957). The aggre...

Cumulative logics are studied in an abstract setting, i.e., without connectives, very much in the spirit of Makinson’s [11] early work. A powerful representation theorem characterizes those logics by choice functions that satisfy a weakening of Sen’s property α, in the spirit of the author’s [9]. The representation results obtained are surprisingly smooth: in the completeness part the choice fu...

This research report presents an extension of Cumulative of Choco constraint solver, which is useful to encode over-constrained cumulative problems. This new global constraint uses sweep and task interval violation-based algorithms.

The effects of cell density on drug-induced cell kill kinetics were studied by means of clonogenic assay using 3 human leukaemia-lymphoma cell lines. Mitoxantrone, daunorubicin, doxorubicin, vincristine and bleomycin were progressively less efficacious when cell density increased (positive inoculum effects), whereas the effects of cis-platin and carboplatin were not influenced by cell density. ...

In this paper, borrowing the intuition in Rao et al. (2004), we introduce a cumulative version of the inaccuracy measure (CIM). Also we obtain interesting and applicable properties of CIM for different cases based on the residual, past and interval lifetime random variables. Relying on various applications of stochastic classes in reliability and information theory fields, we stu...

In a narrow critique of two early papers in the literature on cumulative cultural evolution, Vaesen et al. (1) misunderstand the work they criticize, mischaracterize multiple lines of research, and selectively ignore much evidence. While largely recycling prior criticisms, they provide no new models, evidence, or explanations (2). Not only do their criticisms of Henrich’s (3) and Powell et al.’...

Directed acyclic graphs (DAGs) are a popular framework to express multivariate probability distributions. Acyclic directed mixed graphs (ADMGs) are generalizations of DAGs that can succinctly capture much richer sets of conditional independencies, and are especially useful in modeling the effects of latent variables implicitly. Unfortunately, there are currently no parameterizations of general ...

Divergent cumulative cultural evolution occurs when the cultural evolutionary trajectory diverges from the biological evolutionary trajectory. We consider the conditions under which divergent cumulative cultural evolution can occur. We hypothesize that two conditions are necessary. First that genetic and cultural information are stored separately in the agent. Second cultural information must b...
