Despite weak to nonexistent evidence regarding the causal association of trauma and fibromyalgia (FM), literature and court testimony continue to point out the association as if it were a strong and true association. The only data that appear unequivocally to support the notion that trauma causes FM are case reports, cases series, and studies that rely on patients' recall and attribution - very...

We use a quantum analog of the polynomial ringZ[x1,1, . . . , xn,n] to modify the Kazhdan-Lusztig construction of irreducible Hn(q)-modules. This modified construction produces exactly the same matrices as the original construction in [Invent. Math. 53 (1979)], but does not employ the Kazhdan-Lusztig preorders. Our main result is dependent on new vanishing results for immanants in the quantum p...

The variety and complexity of human-made tools are unique in the animal kingdom. Research investigating why human tool use is special has focused on the role of social learning: while non-human great apes acquire tool-use behaviours mostly by individual (re-)inventions, modern humans use imitation and teaching to accumulate innovations over time. However, little is known about tool-use behaviou...

Abstract Although MNEs create inventions both internally and collaboratively with partners as well within across countries, we know very little about the effects that combining such inventive activities have on their profitability. This study develops an invention-based perspective considers how MNEs' profitability is influenced by ways they organize development of organizational boundaries (in...
