The continuous opinion dynamics with group-based heterogeneous bounded confidences is considered in this paper. Firstly, a slightly modified Hegselmann-Krause model is proposed, and the agents are divided into open-minded-, moderate-minded-, and close-mindedsubgroups according to the corresponding confidence intervals. Then numerical simulations are carried out to analyze the influence of the c...

No facet of human development is more crucial than becoming symbol-minded. To participate fully in any society, children have to master the symbol systems that are important in that society. Children today must learn to use more varieties of symbolic media than ever before, so it is even more important to understand the processes involved in symbolic development. Recent research has greatly exp...

We consider complexity issues for a special type of combinatorial auctions, the single-minded auction, where every agent is interested in only one subset of the commodities. First, we present a matching bound on the communication complexity for the single-minded auction under a general communication model. Next, we prove that it is NP-hard to decide whether Walrasian equilibrium exists in a sin...

The goal of many randomized experiments and quasi-experimental studies in economics is to inform policies that aim to raise incomes and reduce economic inequality. A policy maximizing the sum of individual incomes may not be desirable if it magnifies economic inequality and post-treatment redistribution of income is infeasible. This paper develops a method to estimate the optimal treatment assi...

Uncritical assumptions about the perfect rationality of AI—coupled with single-minded focus on profit maximization and rational efficiency in organizations—have resulted business leaders believing that they can delegate critical morally sensitive decision-making to AI, potentially resulting harmful outcomes. As we will argue, education thus far has been largely complicit enabling such aspects A...

The Drosophila Single-minded and Tango basic-helix-loop-helix-PAS protein heterodimer controls transcription and embryonic development of the CNS midline cells, while the Trachealess and Tango heterodimer controls tracheal cell and salivary duct transcription and development. Expression of both single-minded and trachealess is highly restricted to their respective cell lineages, however tango i...
