Frivolous Units: Wider Networks Are Not Really That Wide

Are Social Networks Really Balanced?

There is a long-standing belief that in social networks with simultaneous friendly/hostile interactions (signed networks) there is a general tendency to a global balance. Balance represents a state of the network with lack of contentious situations. Here we introduce a method to quantify the degree of balance of any signed (social) network. It accounts for the contribution of all signed cycles ...

Are Nonsignificant Differences Really Not Significant?

Many researchers and reviewers hesitate to publish data when treatments are not “significantly” different. Most of us were taught to use a particular probability value (usually 5% or 1%) as a critical value to test hypotheses. The term “significant” has come to be synonymous with the phrase “significant at the 5% level.” Using relatively conservative critical values prevents readers from evalua...

Are technological and social networks really different?

MULTIPLICATION MODULES THAT ARE FINITELY GENERATED

Let $R$ be a commutative ring with identity and $M$ be a unitary $R$-module. An $R$-module $M$ is called a multiplication module if for every submodule $N$ of $M$ there exists an ideal $I$ of $R$ such that $N = IM$. It is shown that over a Noetherian domain $R$ with dim$(R)leq 1$, multiplication modules are precisely cyclic or isomorphic to an invertible ideal of $R$. Moreover, we give a charac...

Peer-Selected “Best Papers”—Are They Really That “Good”?

BACKGROUND Peer evaluation is the cornerstone of science evaluation. In this paper, we analyze whether or not a form of peer evaluation, the pre-publication selection of the best papers in Computer Science (CS) conferences, is better than random, when considering future citations received by the papers. METHODS Considering 12 conferences (for several years), we collected the citation counts f...
