Antler Tine Scraper Handles in the Central Plains

Abstract

In the perspectives of archaeology, it is evident that the widespread antler-handled fleshing adz used by most historic Plains Indian tribes was preceded in the region by other types of hafted skin-working tools. These, inferentially, varied in construction and materials from area to area, but were everywhere provided with planoconvex chipped stone blades - the familiar and omnipresent end scraper of the Plains. In early historic times in the Central Plains, curved antler handles with stone blades are thought from archaeological evidence to have been used not in adz fashion but with a pushing motion, away from the operator. The relative abundance, variety in size and form, and longevity as an artifact type of the plano-convex end scraper raises various questions that invite further inquiry.     

High Plains wheat mosaic virus: An enigmatic disease of wheat and corn causing the High Plains disease

Brief historyIn 1993, severe mosaic and necrosis symptoms were observed on corn (maize) and wheat from several Great Plains states of the USA. Based on the geographical location of infections, the disease was named High Plains disease and the causal agent was tentatively named High Plains virus. Subsequently, researchers renamed this virus as maize red stripe virus and wheat mosaic virus to represent the host and symptom phenotype of the virus. After sequencing the genome of the pathogen, the causal agent of High Plains disease was officially named as High Plains wheat mosaic virus. Hence, High Plains virus, maize red stripe virus, wheat mosaic virus, and High Plains wheat mosaic virus (HPWMoV) are synonyms for the causal agent of High Plains disease.TaxonomyHigh Plains wheat mosaic virus is one of the 21 definitive species in the genus Emaravirus in the family Fimoviridae.VirionThe genomic RNAs are encapsidated in thread‐like nucleocapsids in double‐membrane 80–200 nm spherical or ovoid virions.Genome characterizationThe HPWMoV genome consists of eight single‐stranded negative‐sense RNA segments encoding a single open reading frame (ORF) in each genomic RNA segment. RNA 1 is 6,981‐nucleotide (nt) long, coding for a 2,272 amino acid protein of RNA‐dependent RNA polymerase. RNA 2 is 2,211‐nt long and codes for a 667 amino acid glycoprotein precursor. RNA 3 has two variants of 1,439‐ and 1,441‐nt length that code for 286 and 289 amino acid nucleocapsid proteins, respectively. RNA 4 is 1,682‐nt long, coding for a 364 amino acid protein. RNA 5 and RNA 6 are 1,715‐ and 1,752‐nt long, respectively, and code for 478 and 492 amino acid proteins, respectively. RNA 7 and RNA 8 are 1,434‐ and 1,339‐nt long, code for 305 and 176 amino acid proteins, respectively.Biological propertiesHPWMoV can infect wheat, corn (maize), barley, rye brome, oat, rye, green foxtail, yellow foxtail, and foxtail barley. HPWMoV is transmitted by the wheat curl mite and through corn seed.Disease managementGenetic resistance against HPWMoV in wheat is not available, but most commercial corn hybrids are resistant while sweet corn varieties remain susceptible. Even though corn hybrids are resistant to virus, it still serves as a green bridge host that enables mites to carry the virus from corn to new crop wheat in the autumn. The main management strategy for High Plains disease in wheat relies on the management of green bridge hosts. Cultural practices such as avoiding early planting can be used to avoid mite buildup and virus infections.     

A Shoshonean Origin for the Plains Shield Bearing Warrior Motif

Abstract

The shield bearing warrior is a distinctive motif characteristic of the rock art of the Northwestern Plains. It also occurs commonly in the eastern Great Basin as an element of Fremont rock art. Detailed similarities between Plains and Great Basin shield figures suggest cultural relationships between the two areas. This has led some authors to propose that the motif originated in the Northwestern Plains and diffused to the Great Basin. Others argue that the motif spread from the Great Basin to the Plains. Relative dates recently obtained for shield figures at Northwestern Plains sites support the latter hypothesis. A Shoshonean origin for the Northwestern Plains shield figures is suggested by the dates, and the coincidence between the distribution of the motif, the distribution of diagnostic Shoshonean artifacts. and the ethnohistorically known range of the Plains Shoshone. It is suggested that the Shoshone borrowed the motif from the Fremont Culture during a period of interaction between the two groups.

The shield bearing warrior, a distinctive motif that depicts a pedestrian warrior whose body is represented by a large circular shield (Fig. 1), is frequently encountered in the rock art of the western United States. It is especially common at sites on the Northwestern Plains and in the eastern Great Basin (Fig. 2).

Three ethnographic examples, two from the Plains and one from Australia, of the process of sharpening chipped stone tools with the teeth are noted.     

Jackson Fall-Leaf: A Multi-Component Occupation Site Inc Northeasternc Oklahoma

Abstract

The Jackson Fall-Leaf site is a deeply buried multi-component occupation site located in the Little Caney River Valley of Northeastern Oklahoma. The site, situated in the Cross Timbers province on the southeastern periphery of the Southern Plains, contains cultural debris from the Woodland and Plains Village periods. Excavation produced a large quantity of chipped stone artifacts and allowed the delineation of an activity area within the site. Typological cross dating, in combination with intensive paleo-environmental research at the site and at other locales in the Copan area, indicates that the site dates from the period between A.D. 500 and A.D. 1300.     

The Sister’s Hill Site: A Hell Gap Site In North-Central Wyoming

Abstract

The cultural horizon at the Sister’s Hill Site has produced typical Hell Gap points and a small group of associated artifacts. The radiocarbon date of 9650 ± 250 B. C. is in agreement with late Agate Basin or early post Agate Basin sites in the High Plains. On the basis of the current data, Hell Gap points appear to have developed from Agate Basin styles and seem to be developmental to Alberta, Scottsbluff and Eden types.     

Investigation of the Swift Bird House (39DW233) in the Oahe Reservoir,South Dakota

Abstract

The Swift Bird House (39DW233) is a prehistoric structure of indeterminate characteristics. The associated artifacts are directed to a Northern Plains horticulture and hunting complex. A tenuous relationship to the Anoka Focus and a possible occupation date of about A. D. 1500 is suggested for the site     

The Pelland and Moe Site Blades: Paleo-Indian Culture History in the Upper Midwest

Abstract

Analysis of artifacts recovered from the Moe site located in northwestern North Dakota reveals the presence of 15 blades and three blade-like flakes, the majority of which are made of Knife River Flint and have been modified by retouch flaking. A comparison of the Moe specimens to those from the Pelland site in northern Minnesota, the only other site from the study area which contains blades of Paleo-Indian age, indicates that the Moe specimens are smaller in all dimensions. The Pelland specimens are made of Knife River Flint and have been modified by retouch flaking. Examination of the literature on Paleo-Indian sites from the Plains region indicates that blade production is more common in Plano cultures particularly Agate Basin and Plainview-Goshen than in earlier Clovis or Folsom cultures or later Cody cultures. It is suggested that the Pelland and Moe site blades are Plano in age and most likely Agate Basin or Plainview-Goshen in cultural affiliation. A model provided by Leo Pettipas (1976) is used to suggest an eastward movement of Plains Plano cultures using Knife River Flint across southern Manitoba, eastern North Dakota, and into western and northern Minnesota following the recession of Glacial Lake Agassiz.     

The Grass Valley Horse

Abstract

The head and part of the neck of a baked clay horse figurine from an archaeological site in Lander County is described. It suggested the presence of the Grass Valley horse in Central Nevada reaffirms the strong cultural ties between the PlateauShoshone and the buffalo hunting; horse-nomad Shoshone of the Western Plains, ties already indicated by Shoshone pottery and other plains type artifacts indigenous to the area.     

Hell Gap: Paleo-Indian Occupation on the High Plains

Abstract

A resume of archaeological investigations in the Hell Gap Valley of southeastern Wyoming is presented. This research produced a detailed sequence of Plains PaleoIndian occupation of this section of the High Plains. from about 9000 to 5500 B.C. Identifiable complexes recognized include Goshen, Midland, Folsom, Agate Basin, Hell Gap, Alberta, Cody, and Frederick. Materials recovered represent camping activities rather than the better known game kills, and add dimension to our knowledge of Plains Paleo-Indian cultures.     

From Band To Tribe On The Plains11

Abstract

Cultural ecologists, such as Steward and Shirnkin, hold that the core features of a culture, namely socio-political systems, are closely related to subsistence activities and economic arrangements which, in turn, are influenced but not ecessarily determined by the natural habitat of the group. A study of the Plains adaptations of the Piegan, Kiowa, Comanche, Plains Cree, and Plains Shoshone throw some doubt on this the sis. The Piegan (and other Blackfoot tribes), Plains Shoshone, and Kiowa share common forms of political organization with other Plains tribes but the Comanche and Plains Cree represent atypical cases in. this regard. The first three tribes developed pan-tribal sodalities while the latter two did not do so. The presence or absence of these pan-tribal sodalities conditioned the extent to which tribal integration occurred in these groups. The subsistence activities of these tribes alone do not account for the weak or strong development of pan-tribal structures. Factors in the total environment of each tribe, or niche, account for these differences. These differences in political organization cannot be attributed solely to differences in subsistence activities nor economic arrangements as they are influenced by the specific natural habitat of each tribe.     

A Possible Paleo-Indian and Archaic Site in the Swan Valley,Manitoba

Abstract

An archaeological site uncovered in the Swan Valley of Manitoba during road construction yie1ded a small group of artifacts including a Paleo-Indian projectile point and side-notched Archaic points. The site is significant as it lies in a corridor which probably served as a vital migration route between the Northern Plains and the diminishing lakes within the Lake Agassiz Basin.     

The Yuwipi Cult of the Oglala and Sicangu Teton Sioux

Abstract

The Yuwipi Cult of the Teton Sioux falls into the category of the Plains darkened room or darkened tent ceremonies involving monsters, usually diminutive. This type of ceremony with the tieing and subsequent freeing of the shaman by his personal spirits is old on the Plains but is also a circumpolar complex. A Woodland past, with some elements surviving from the even earlier southeastern home, is evident in various practices and artifacts connected with the cult.

The author takes issue with a previous statement that Yuwipi is like the Peyote cult marginal to the Teton religion. Rather, Yuwipi embodies all the basic elements of Teton cultism while peyotism lacks many of these.

A specific Yuwipi meeting is described in detail the preliminary arrangments with the shaman, sweat bath procedures, food preparation for the ceremony, preparation of the meeting room, as well as the altar and sacred area, scarification of volunteers, and finally the lightsout sessions of the Yuwipi ceremony.

It is concluded that, despite rrany stories of trickery common throughout the Sioux country, Yuwipi devotees continue to believe in the power of the Yuwipi men.     

Cody Knives and the Cody Complex in Plains Prehistory: A reassessment

Abstract

Discovery of the oldest dated Cody Knife in the New World calls for a redefinition of the Cody Complex in High Plains prehistqw. Its greater antiquity plus its association with an earlier culture gives new insight into the developmental sequence of certain Paleo-Indian tools.     

The Operative Treatment of Scapula Fractures: An Analysis of 10,097 Patients

BackgroundThe indications for operative treatment of scapula fractures have been debated over the past decade. Our purpose was to determine 1) the incidence and trends in the operative treatment of scapula fractures, 2) the incidence of conversion from operative fixation to total or hemi-shoulder arthroplasty (THSA) and 3) rates of associated injuries in scapula fractures. We hypothesized that the operative treatment of scapula fractures is increasing over time and that scapula fractures treated with open reduction and internal fixation (ORIF) would have increased risk for conversion to THSA.MethodsThe Humana Inc. administrative claims database was queried from 2008 to 2015. Patients with any scapular fracture, ORIF of scapula fracture, total or hemi-shoulder arthroplasty, and associated injuries were identified by ICD-9 and CPT codes. Analysis was performed for 1) all patients with a scapula fracture undergoing operative fixation (i.e. ORIF and THSA), 2) all scapular fractures treated with ORIF with subsequent conversion to ipsilateral THSA, and 3) all associated injuries.ResultsThere were 10,097 scapula fractures (28.4% glenoid, 48% female). 60% occurred in patients 65 years and older. There were 198 (1.96%) fractures (70% glenoid) treated with ORIF. There were 287 (2.84%) fractures (45% glenoid) treated with THSA (76% total shoulder). The rate of ORIF of scapular fractures did not significantly increase (RR=0.87, p=0.58). There was a significant increase in THSA as primary treatment of scapula fractures in 2015 compared to 2007 (RR=0.43, p=0.0016). Conversion from ORIF to THSA was 12.6% (25/198). Scapula fractures treated with ORIF were at significant risk for conversion to THSA (RR=4.77, p<0.0001). Associated injuries occurred in nearly 50% of scapula fractures—other fractures, lung contusion and pneumothorax/hemothorax ranking the highest, accounting for 37%, 14.5% and 8.3% of all associated injuries, respectively.ConclusionThe incidence of operative treatment of scapula fractures was 1.96% and 2.84% for ORIF and THSA, respectively. Scapular fractures previously treated with ORIF were at significant risk for conversion to THSA. Although ORIF in scapular fractures did not significantly increase over time, both THSA and overall (ORIF+THSA) operative treatment of scapula fractures increased significantly.

Plains Apache Archaeology: A Review

Abstract

A review of the literature on the Dismal River Aspect in the light of recent additional work at Plains Apache sites has led to more specific suggestions as to probable sources of various Dismal River traits. Most of the traits that appear to have been borrowed from sedentary neighbors seem to have an eastern Plains origin. Many trade items from the Southwest may have been secured from or through the Jicarilla Apaches. Frequency of some triJ, its at Dismal River sites form a gradient from north to south. Many problems remain unsolved.     

The Scoggin Site: a Study in Mckean Typology

Abstract

The Scoggin Site, an Early Middle Period Bison kill in south-central Wyoming, yielded two distinct stylized projectile point varieties from the one bone layer present. This single component affords optimum opportunity to study the two varieties of points in one context. The technology for the projectile point assemblage is described, and literature concerning the deep side-notched Early Middle Period or Archaic age points from the Northwestern Plains and the northern Great Basin is discussed.

In order to discover if the deep side-notched projectile points from Scoggin (reminiscent of much later projectile point types) were indeed part of the McKean classification, their dimensions were compared to those of the indented base McKean lanceolate projectile points from the same site. The measurements overlap or can be otherwise explained for both lanceolate and side-notched forms. The Statistical Package for the Social Sciences (SPSS) was used to demonstrate that the two types of points are quite homogeneous.

The question as to why the points differ stylistically has several possible answers. For example, the two types may represent interacting but identifiable ethnic groups, or the numerical superiority of the side-notched point may reflect hafting superiority. At any rate, the deep side-notched point is an integral part of the Early Middle Period and can be classified as McKean.     

The AvonLea Point

Abstract

The authors define a readily distinguished type of small, triangular, side-rotched projectile point previously assigned to the Late Prehistoric Period of the northwestern Plains but which was thought too generalized to be used in studies of cultural and ethnic affiliation.

Type sites are described, geographical distributions made, and factors considered which may have influenced the development of this point type in southwestern Saskatchewan.

It is concluded that the Avonlea point is sufficiently unique and temporally delimited to serve as a useful marker for the early Late Prehistoric Period in the northwestern Plains.     

Experimental Artifacts and the Analysis of Ligand Binding Data: Results of a Computer Simulation

Abstract

Use of computerized analysis techniques for ligand binding data have recently become generally available, and are now used quite routinely. When used appropriately, these tools can improve the precision of the estimated parameters for binding affinity, K, and capacity, R. Furthermore, such programs can also calculate the uncertainty of the estimates e.g., as a percent coefficient of variation (%CV). However, because of unmeasured variability in specific activity, tracer purity, counting efficiency, counter background, efficiency of separation, etc., the actual uncertainty in the parameters K and R is usually much larger than stated. In an attempt to examine the effects of such artifacts, we have developed a computer program which simulates data arising from a number of commonly used experimental designs, and then intentionally distorted with each of these artifacts. Finally, the data are converted to B/F and B and plotted in the conventional Scatchard plot. Distortions revealed in this graph are indicative of the effect each artifact has on the parameter estimates. The computer program is generally written to simulate the binding of 2 or more ligands to one, two or many classes of independent or cooperative specific sites as well as to nonspecific sites. Thus, the program is applicable in a wide variety of situations. Results show that low tracer purity (“bindability”) or low filtration efficiency will significantly alter the measured R value. Poorly determined specific radioactivity may significantly alter the measured K value as well. Imprecise measurement of machine background may result in the specious appearance of positive cooperativity, or of additional high or low affinity classes of binding sites. Finally, under some circumstances, it is possible to detect and correct for the presence of these artifacts.
