Population III by Popular Demand - Progress and Previews

I discuss the ongoing search for stars of the Milky Way which have been referred to as members of Population III. Following a discussion of possible definitions for these stars, I consider the reasons why astronomers have undertaken this search, and list some of the numerous astrophysical uses of the extremely metal-poor stars found along the way. I then review survey techniques which have been used in the past, and provide an update on plans for future investigations. Finally, the question of when one might consider the search for Population III Finished is addressed.Comment: 12 pages, 0 figures, to appear in proceedings of THE FIRST STARS meeting, held in Garching, Germany, August 199

Three New Species and a Key for the Genus Callidora (Hymenoptera: Ichneumonidae)

Excerpt: The genus Callidora (subfamily Porizontinae) has traditionally contained a single European species, Callidora albovincta (Holmgren). Townes (1969) redefined the genus and included a second species (Campoplex analis Gravenhorst). At the same time he referred to three undescribed species, two from North America and one from the Philippines. Descriptions of these three are presented here together with a key to all five species now in Callidora. Several relationships within this genus are noteworthy. The two North American species, tegularis and surata, are morphologically most alike. Quite distinct from these, but similar in body shape and propodeal sculpture is the European species analis. The remaining two, albovincta and atrognatha, have distinctive propodeal carinae in addition to a thorax which is more elongate in profile than that of the other species. Thus Callidora can be divided into two species groups which are easily distinguished on the basis of body shape and propodeal sculpture

Mississippian Communities in the St. Francis Basin: A Central Place Model

The development of Mississippian settlement models for northeast Arkansas is reviewed. It is argued that a five-tier central place hierarchy best accounts for the variability currently known to exist among Mississippian communities in the St. Francis basin

On base sizes for actions of finite classical groups

Let G be a finite almost simple classical group and let ? be a faithful primitive non-standard G-set. A base for G is a subset B C_ ? whose pointwise stabilizer is trivial; we write b(G) for the minimal size of a base for G. A well-known conjecture of Cameron and Kantor asserts that there exists an absolute constant c such that b(G) ? c for all such groups G, and the existence of such an undetermined constant has been established by Liebeck and Shalev. In this paper we prove that either b(G) ? 4, or G = U6(2).2, G? = U4(3).22 and b(G) = 5. The proof is probabilistic, using bounds on fixed point ratios

Problem of Site Definition in Cultural Resource Management

The strategies employed by the Cache River Archeological Project, the Little Black Watershed Project, and the 1976 Village Creek Archeological Project with regard to site definition are compared and assessed. It is argued that both the Cache and Little Black Projects used unnecessarily restrictive definitions of cultural resources. The more liberal approach of the Village Creek Project enables both the archeological community and governmental agencies to interpret and assess better the significance and general extent of the archeological context of the cultural resource base
