Matrix Roots of Eventually Positive Matrices

Eventually positive matrices are real matrices whose powers become and remain strictly positive. As such, eventually positive matrices are a fortiori matrix roots of positive matrices, which motivates us to study the matrix roots of primitive matrices. Using classical matrix function theory and Perron-Frobenius theory, we characterize, classify, and describe in terms of the real Jordan canonical form the $p$th-roots of eventually positive matrices.Comment: Accepted for publication in Linear Algebra and its Application

Did intelligence matter in the Cold War?

For forty years the superpower conflict between the United States and the Soviet Union dominated the world stage. In popular culture the conflict produced a plethora of “spy” books and films about the daring exploits of intelligence agents. In contrast, the scholarly investigation of the role of intelligence in the Cold War had to await the gradual opening, since 1990, of “Top Secret” archives. It is now time to make a first attempt at assessing the role that intelligence played in the overall development of the conflict. Did intelligence help to avoid the Cold War becoming “hot”? We have invited three prominent intelligence scholars to give their views

The Fruitcake Capital of the World

Two different fruitcake companies in the same small town are discussed and their widely different strategies are presented. Each of the entrepreneurs began working with a “master baker” as little boys but later followed different paths to develop a successful fruitcake business. A brief history of the fruitcake is offered as evidence that the product has been around for hundreds of years and will likely not go away anytime soon in spite of the ridicule and humor that has surrounded fruitcakes during the past twenty-five years

A Cross Country Comparison of Best Practices in Recruitment and Selection

This study examines best practices in hiring related to the recruitment and selection process in English-speaking countries with an Anglo-Saxon heritage. Since such countries share a similar cultural backgrounds and histories, best practices are likely to be somewhat similar. Studies of best practices were examined in the following countries: United States of America, Australia, United Kingdom, Canada, and New Zealand. After looking at commonalities across “best practices” studies, the current investigation presents a common set of such practices in terms of usage

The changing face of the Portuguese parties : strategic innovation and the dimensionality of the party policy space

We provide a comprehensive analysis of the Portuguese parties and their policy space. We show how and how well the parties have been able to adapt to the changing environment in the party system. Our analyses show that, not only are we able check existing static expert assessments of the Portuguese party and policy space, but we are also able to track the dynamics of the system. In this way, we expand on what little has been said thus far about the Portuguese party system. We conclude with three important ideas. First, we confirm that the Portuguese policy space is unidimensional, with the parties lining up from Left to Right, as some but not all experts, have suggested. Second, we propose that the environment of the Portuguese party system is one of compression, that is, parties have been office-seekers in that they have all been approaching the Centre of the political spectrum for a number of reasons we explore in detail. Last, we learn that only through issue dimensions and how parties pronounce themselves on these dimensions are the smaller parties able to survive and avoid extinction in the compressing environment of the party system
