The objective of this research is to provide a statistical measurement to predict the likely winners of international football tournaments with particular reference to the Euro 2008 football tournament. This research argues that there exists a positive relationship between the competitive balance and success in international football tournaments. The level of the competitive balance in a domest...

This paper used the Fédération International de Football Association (FIFA) world ranking points data to examine how linguistic heterogeneity has an impact on technology transfer from the most developed countries. The major findings are: (1) the learning effect from the most developed countries on team performance is larger for developing countries than for developed countries. (2) Linguistic h...

important producer countries of wood and paper products are identified by this study. identification of these countries is important for trade of wood and paper products. ranking of different regions of the world was done using mean values of the production based on fao 10 years reports from 1998 to 2007. results showed that the production value for the major part of the products was almost con...

Energy consumption has been essential to societies; because societies depend on the rising provisions of energy to meet their requirements for goods and services and endorse sustainable development. The major source of energy nowadays is oil; oil consumption is dependent on oil availability, production and price. Several Arab countries are considered as major suppliers of oil in the world; cons...

We study the (parameterized) complexity of SHIFT BRIBERY for multiwinner voting rules. We focus on the SNTV, Bloc, k-Borda, and Chamberlin-Courant, as well as on approximate variants of the Chamberlin-Courant rule, since the original rule is NP-hard to compute. We show that SHIFT BRIBERY tends to be significantly harder in the multiwinner setting than in the single-winner one by showing setting...

The recent years have witnessed an increasing attention to the methods of multiple attribute decision making in solving the problems of the real world due to their shorter time of calculation and easy application. One of these methods is the ‘permutation method’ which has a strong logic in connection with ranking issues, but when the number of alternatives increases, solving problems through th...

The goal of this paper is to propose and study properties of multiwinner voting rules (with a particular focus on rules based in some way on single-winner scoring rules). We consider, e.g., SNTV, Bloc, k-Borda, STV, and several variants of Chamberlin–Courant’s and Monroe’s rules, identify two natural approaches to defining multiwinner rules, and show that many of our rules can be captured by on...
