Epistemic logic in the tradition of Hintikka provides, as one of its many applications, a toolkit for the precise analysis of certain epistemological problems. In recent years, dynamic epistemic logic has expanded this toolkit. Dynamic epistemic logic has been used in analyses of well-known epistemic “paradoxes”, such as the Paradox of the Surprise Examination and Fitch’s Paradox of Knowability...

In recent years, strategic fit issues attract both academia and practitioners due to the debate of productivity paradox of information system (IS). This study provides a comprehensive literature review on the strategic fit issues in IS research and suggest some future research directions. In detail, conceptualization of strategic fit in IS research, operationalization of related constructs, and...

In 1903 Russell’s paradox came over the mathematical world with a double stroke. Bertrand Russell himself published it under the heading “The Contradiction” in chapter 10 of his Principles of Mathematics (Russell 1903 ). Almost at the same time Gottlob Frege (1848–1925) referred to Russell’s paradox in the postscript of the second and final volume of his Grundgesetze der Arithmetik (Frege 1903 ...

Governments want to provide a better life for their citizens all over the world. It is common thinking that people living in country with higher GDP, have satisfaction level. Richard Easterlin firstly challenged this idea, supporting increases after certain point GDP are meaningless developed countries. There many studies both support and criticize called “Easterlin Paradox”. This study aims ex...

Modeling and measurement issues have been considered the heart of information technology (IT) productivity paradox problem. By collecting data from seven mortgage ®rms, this research attempts to shed light on the causal relationships and complementarity properties among IT and performance variables. The result is a multi-level business value model that connects the use of IT to a ®rm's pro®t. I...

In this paper I take a closer look at a recently published paradox by Göran Sundholm involving the notion of knowability. I point out that this paradox is not a novel, genuine paradox, but rather an important variant of the Knower Paradox. I briefly discuss further variations of the Knower Paradox, and in a final section I try to show that it is not unproblematic to assume that knowability is f...

Parrondo’s paradox is a well-known situation where losing strategies can be combined to win, and is based on a thermodynamic Brownian ratchet principle. We demonstrate a new extension of Parrondo’s paradox called the Allison mixture where it is possible to paradoxically generate random sequences with nonzero autocovariance, out of subsequences of zero autocovariance. We explain the effect with ...

Geometric complexity theory (GCT) is an approach towards the P vs. NP and related problems. The article [GCTflip] describes its defining strategy, called the flip, to resolve the self referential paradox, which is the root difficulty in these problems. This article describes an approach based on positivity hypotheses in algebraic geometry and representation theory to implement the flip and ther...

Anaemia is a major public health issue in India today. Anemia can be called our national disease and in fact it is a national calamity. The figures for anemia among women and children of India are truly staggering. It is estimated that more than half of all Indian women and ¾th of Indian children suffer from anemia. The paradox about anemia is that, in India the level of anemia does not seem to...

One of the interesting phenomena due to topological heterogeneities in complex networks is the friendship paradox: Your friends have on average more friends than you do. Recently, this paradox has been generalized for arbitrary node attributes, called the generalized friendship paradox (GFP). The origin of GFP at the network level has been shown to be rooted in positive correlations between deg...
