We prove an identity conjectured by Adin and Roichman involving the descent set of λ-unimodal cyclic permutations. These permutations appear in the character formulas for certain representations of the symmetric group and these formulas are usually proven algebraically. Here, we give a combinatorial proof for one such formula and discuss the consequences for the distribution of the descent set ...

Excavations undertaken in 1980 in the western Coronation Gulf area, arctic Canada, are described. Work concentrated on the Clachan site (NaPi-2), a small Thule winter village. Stylistic analysis of the artifacts recovered suggests affiliation with Alaskan rather than Canadian Thule, despite a comparatively recent date for the site. Also briefly described are two “protohistoric” Copper Inuit sit...
