Based on the 2019 satellite remote sensing data, survey was conducted open-pit stopes of building sand mines in Shigatse, Tibet, and relationship between number area, population density district/county, as well distribution characteristics main built-up areas, administrative villages traffic roads at county level were analyzed. This study tentatively links open pit mine with human aggregation a...

Several recent articles have studied judgment aggregation rules under the point of view of the normative properties they satisfy. However, a further criterion to choose between rules is their computational complexity. Here we review a few rules already proposed and studied in the literature, and identify the complexity of computing the outcome.

The new …eld of judgment aggregation aims to …nd group judgments on logically interconnected propositions. Recent impossibility results have established limitations on the possibility to vote independently on the propositions, hence notably on the possibility to use quota rules (rules with acceptance thresholds for the propositions). I show that, fortunately, the impossibilities fail to apply t...

Judgment aggregation investigates the problem of how to aggregate several individuals’ judgments on some logically connected propositions into a consistent collective judgment. The majority of work in judgment aggregation is devoted to studying impossibility results, but the relationship between the (social) dependencies that may exist between voters and the outcome of the voting process is tra...

How should we aggregate the ex ante preferences of Bayesian agents with heterogeneous beliefs? Suppose state world is described by a random process that unfolds over time. Different have different beliefs about probabilistic laws governing this process. As new information revealed time process, update their and via Bayes rule. Consider Pareto principle applies only to which remain stable in lon...

From bird flocks to fish schools and ungulate herds to insect swarms, social biological aggregations are found across the natural world. An ongoing challenge in the mathematical modeling of aggregations is to strengthen the connection between models and biological data by quantifying the rules that individuals follow. We model aggregation of the pea aphid, Acyrthosiphon pisum. Specifically, we ...
