A insurreição contestada: William Styron e As confissões de Nat Turner

This work presents intricacies of "truth" in the historical novel Confessions of Nat Turner, by William Styron, considering the point-of-view of the novel's narrator. When speaking about the black, Styron somehow keeps the white's perspective, and also perpetuates the distance created by the slavery and segregationist system of the United States of America.

William Boyce White, Jr. Papers - Accession 1488

The William Boyce White, Jr. Papers consists of his genealogical research as well as his research related to the history of York County and Rock Hill, SC. The papers also include records and manuscripts relating to several of his published works. Mr. White is a Rock Hill native and taught at the Winthrop Training School (WTS) from 1958-1965 and taught at Rock Hill High School following the closing of the high school portion of the WTS. He also taught in Clover before coming to Winthrop. He was the organist at First Presbyterian Church in Rock Hill from 1945 until he moved to Virginia. His interest in local history covers the Rock Hill train depot (included in the collection is a tintype of the original depot ca. 1860s), Colonel William Hill, the Catawba River, Catawba Indians, Rock Hill and York County schools, historic homes (includes several photographs, many of which were used by Elizabeth Reed in her long running series on historic homes in Rock HillEvening Herald), local churches, as well as Rock Hill, Fort Mill, Blackstocks, and York County in general. Of special interest is a copy of the Indian Land Chronicle dated January 21, 1859. Only three copies of the Chronicle are known to exist in the state of South Carolina. The genealogical research conducted by Mr. White covers many of the prominent names of York County and of South Carolina in general. Below is a list of the prominent family names covered in Mr. White’s research: Anderson; Bankhead; Barringer; Bell; Black; Button; Campbell; Carpenter; Coffey; Cowan; Crawford; Culp; Davis; Fennell; Fewell; Graham; Hanna; Hayes; Hill; Hutchison; Irwin/ Erwin; Johnson; Lee; Martin; Massey; McClain; McConnell; McCullough; McFadden; Miller; Mobley; Morrow; Neely; Neil; Patton; Pettus; Plexico/Plaxco; Rives; Robinson; Roddey; Setzer; Stephenson; Strait; Sturgis; Sutton; Templeton; Waggoner; Wallace; Wherry; White; Williams; Williamson; Workman; Wylie.

The collection consists of a photocopy of a typescript account of William Joseph Miller’s experiences as a soldier in the Confederate army, 12th Regiment, South Carolina Volunteers detailing his role in campaigns in South Carolina, Virginia and Maryland. Also included is a genealogy of William Joseph Miller’s family with his dates of birth and death and a photograph of Miller.

A Memorial for William V. Sliter

William V. (Bill) Sliter, an internationally known micropaleontologist and research geologist for the U.S. Geological Survey, passed away suddenly, October, 1997, while talking to a colleague in his office. In his honor, B. Huber, T. Bralower, and M. Leckie organized a keynote symposium ‘‘Paleoecological and Geochemical Signatures of Cretaceous Anoxic Events’’ at the 1998 annual meeting of the Geological Society of America in Toronto, Canada. This theme issue of the Journal of Foraminiferal Research contains the published papers from the symposium and is dedicated to his memory.

Dynamics of cell and tissue genesis in the male reproductive system of ticks (Acari: Ixodidae) Amblyomma cajennense (Fabricius, 1787) and Amblyomma aureolatum (Pallas, 1772): a comparative analysis

Ticks are classified into three families: Argasidae, Ixodidae, and Nutalliellidae. The taxonomy and phylogeny within Ixodidae are still discussed by the specialists, thus requiring further studies. Amblyomma cajennese and Amblyomma aureolatum (Brazil) belong to two species complexes known as “cajennese” and “ovale”, respectively, and are directly related to the transmission of the Brazilian spotted fever. This confirms the medical and veterinary significance of these species, as well as the need for further morphological studies that will bring a better understanding of their taxonomy, phylogeny, and control. In this context, the present study aimed to characterize the morphology of the male reproductive system of A. cajennese and A. aureolatum when unfed and after 4 days of feeding, thereby seeking to: (a) distinguish the two species or “complexes”, and (b) study an internal system which has the potential to be targeted by acaricides. Therefore, males from both species (unfed and after 4 days of feeding) were cold-anesthetized, dissected, and had their reproductive systems removed for histological analysis. The results showed that the morphology of the male reproductive system is generally similar between both species, like in other Ixodidae ticks, exhibiting a multilobed accessory gland complex related to seminal fluid secretion, a pair of vasa deferentia and a pair of testes housing germ cells (spermatocytes) in different stages. The main differences were found in the development of the accessory gland complex cells and germ cells, showing that the maturation of the male reproductive system starts later in A. aureolatum, when compared to A. cajennese. However, during the blood meal, A. aureolatum development is increased, thus making germ cell maturation and gland complex activity higher than in A. cajennese. This study shows the differences in the development of the male reproductive systems of both species, while providing information that can assist in the establishment of new control methods.
