The article is a brief summary of current research results of the authors in the field of spatial modeling of air pollution based on spatio-temporal data streams from geosensor networks. The urban environment is characterized by the presence of a large number of different sources of emissions and rapidly proceeding processes of contamination spread. So for the development of an adequate spatial model is required to make measurements with a large spatial and temporal resolution. It is shown that geosensor network provide researchers with the opportunity to obtain data with the necessary spatio-temporal detail. The article describes a prototype of a geosensor network to build a detailed spatial model of air pollution in a large city. To create a geosensor in the prototype of the system, calibrated gas sensors for a nitrogen dioxide and carbon monoxide concentrations measurement were interfaced to the module, which consist of processing unit and communication unit. At present, the authors of the article conduct field tests of the prototype developed.

Sincere Voting

This chapter presents a unified model of legislative elections, parties, and roll call voting, built around a party leadership election. First, a legislative caucus selects a party leader who campaigns based on a platform of a disciplinary system. Once elected, that leader runs the legislative session, in which roll call votes occur. Then elections occur, and incumbents face re-election with the positions they incrementally adopted. When the caucus is ideologically homogeneous, electorally diverse, and policy motivated, members will elect a leader who solves the collective action problem of sincere voting with “preference-preserving influence.” That leader will threaten to punish legislators who bow to electoral pressure to vote as centrists. Consequently, legislators vote sincerely as extremists and get slightly lower vote shares, but they offset that lost utility with policy gains that they couldn’t have gotten without party influence. Party leaders will rarely pressure legislators to vote insincerely.
