This paper studies collective choice rules whose outcomes consist of a collection of simultaneous decisions, each one of which is the only concern of some group of individuals in society. The need for such rules arises in different contexts, including the establishment of jurisdictions, the location of multiple public facilities, or the election of representative committees. We define a notion ...

This project addresses the design of a framework for the development of learning contexts through virtual learning communities, based on the development of learning activities. It endeavours to establish a framework to rethink the management of learning and knowledge as processes of social participation within virtual contexts of collective learning. It builds on the conviction of the importanc...

We define generalized (preference) domains D as subsets of the hypercube {−1, 1}, where each of the D coordinates relates to a yes-no issue. Given a finite set of n individuals, a profile assigns each individual to an element of D. We prove that the outcome of issue-wise majority voting φm belongs to D at any profile where φm is well-defined if and only if this is true when φm is applied to any...

Collective intelligence is the result of the proper aggregation of local information from many individuals to generate an optimal global solution to a problem. Often, these solutions are more optimal than what any individual could have provided. In this article, we focus on prediction markets as the aggregation mechanism for collective intelligence. Prediction markets, like commodity markets, c...

This paper contains a review of the main results of a search of regularities in collective variables properties in multiparticle dynamics, regularities which can be considered as manifestations of the original simplicity suggested by QCD. The method is based on a continuous dialog between experiment and theory. The paper follows the development of this research line, from its beginnings in the ...

Macroeconomic Performance and Collective Bargaining: An International Perspective This paper critically reviews the research on how collective bargaining systems influence macroeconomic performance in industrialized countries. The review considers effects of bargaining level, coordination, and corporatist institutional arrangements. Key empirical results turn out to be quite fragile, and much o...

We show that the system where CP 1 model coupled to Hopf term can reveal fractional spin in a collective coordinate quantization scheme, provided one makes a transition to physically inequivalent sector within a same solitonic sector characterized by a nonvanishing topological number

In a mixed strategy, game-theoretical scenario mimicking the behaviour of fishing vessels competing for a limited renewable resource, agents following either a Collective Intelligence or a purely selfish strategy quickly outperform fully-cooperative teams as well as agents not planning for future action by acting randomly. The stable balance between fully selfish agents and the Collective Intel...

We use the Method of Collective Marks to analyze some time-dependent processes in the M/G/1 queue with single and multiple vacations. With the server state specified at a fixed time t > 0, the Laplace transforms with respect to t of mixed transforms for the joint distribution of the number of departures by time t, the queue length, the virtual waiting time, the elapsed and remaining service/vac...
