Further Surface Collecting and Shovel Testing Investigations at the Sanders Site (41LR2), Lamar County, Texas
No full textArchaeological investigations at the Sanders site (41LR2), an important ancestral Caddo mound center and village on the Red River in Lamar County, Texas, have been ongoing since 2013. The latest round of work at the Sanders site primarily concerned Dr. Chester P. Walker’s conducting geophysical work there in December 2014. Bo Nelson went to the site to show Walker the areas where artifactual materials have been collected from surface clusters in earlier investigations.
The weather was cold and rainy the entire time. Dr. Walker was able to work in between rain episodes. The fields were wet and muddy. Most of the Crawford property was planted in winter wheat, except the fields just east of the mounds, that still had dried corn stalks covering the ground surface. The fields with the corn stalks had no surface visibility. The Sanders’ property was recently disked, and there was about 50–60 percent surface visibility.
Mr. R. P. “Dick” Crawford, Julia Crawford’s father, made several visits to the site while Nelson and Walker were there. He has a routine that involves checking for feral hogs, and seeing if there had been any damage they may have done to the fields since his last visit. During his visits, he was able to show to Nelson and Walker a small strip of property that was owned by the Crawford’s that we had originally assumed to be included with the Sanders’ family property. This strip of property extends up to the West mound, making the Sanders’ property “L–shaped” instead of a block–shaped tract
FOURIER TRANSFORM INFRARED EMISSION SPECTROSCOPY AND AB INITIO STUDY OF HBO AND BO
No full textAuthor Institution: Department of Chemistry, University of York, Heslington, York, YO10 5DD, UKThe Fourier-transform infrared emission spectra of HBO and BO were recorded using a Bruker IFS-125HR Fourier transform spectrometer. HBO molecules were synthesized using a high temperature tube furnace at 1450 ^irc}C. Our spectra of the HBO molecule in the cm region contain the and fundamental vibrational modes plus numerous hot bands. An accurate potential energy surface using the MRCI method with correlation consistent core-valence basis sets aug-cc-PCVnZ (n=3, 4, 5) is being calculated and a vibrational configuration interaction (VCI) calculation based on this surface will be performed to assist in the assignment of the HBO hot bands. BO molecules were produced by applying a DC discharge to the furnace containing HBO. Our spectrum of BO in the cm region contains the fundamental bands of both isotopic species, BO, BO, and one hot band of the main isotopologue BO. The fundamental band of BO contains 95 lines roughly equally distributed between the P and R branches. A combined least-squares fit with ground state microwave data was performed to determine the spectroscopic constants. Further results on this ongoing project will be presented
A Descriptivist Refutation of Kripke's Modal Argument and of Soames's Defence
No full textThis article systematically challenges Kripke's modal argument and Soames's defence of this argument by arguing that, just like descriptions, names can take narrow or wide scopes over modalities, and that there is a big difference between the wide scope reading and the narrow scope reading of a modal sentence with a name. Its final conclusions are that all of Kripke's and Soames's arguments are untenable due to some fallacies or mistakes; names are not rigid designators; if there were rigid designators, description(s) could be rigidified to refer fixedly to objects; so names cannot be distinguished in this way from the corresponding descriptions. A descriptivist account of names is still correct; and there is no justification for Kripke's theory of rigid designation and its consequences.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000308094800005&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701PhilosophyA&HCI0ARTICLE3225-2607
Social Constructivism of Language and Meaning
No full textTo systematically answer two questions “how does language work?” and “where does linguistic meaning come from?” this paper argues for Social Constructivism of Language and Meaning (SCLM for short) which consists of six theses: (1) the primary function of language is communication rather than representation, so language is essentially a social phenomenon. (2) Linguistic meaning originates in the causal interaction of humans with the world, and in the social interaction of people with people. (3) Linguistic meaning consists in the correlation of language to the world established by collective intentions of a language community. (4) Linguistic meaning is based on the conventions produced by a language community in their long process of communication. (5) Semantic knowledge is empirical and encyclopedic knowledge distilled and condensed, and the uses of language accepted by a linguistic community. (6) Language and meaning change rapidly or slowly as the communicative practice of a linguistic community does. The crucial point of SCLM is to focus on the triadic relation among language, humans (a linguistic community) and the world, rather than the dyadic relation between language and the world
Socio-historical Causal Descriptivism. A Hybrid and Alternative Theory of Names
No full textThis paper argues for a hybrid and alternative theory of names—Sociohistorical Causal Descriptivism, which consists of six claims: (1) the referring relation between a name and an object originates from a generalized “initial baptism” of that object. (2) The causal chain of the name N fi rstly and mainly transmits informative descriptions of N’s bearer. (3) The meaning of N consists of an open-ended collection of informative descriptions of N’s bearer acknowledged by a linguistic community. (4) With respect to practical needs of agents there is s weighted order in the collection of descriptions of N’s bearer. (5) The meaning or even partial meaning of N, together with the background of a discourse, the network of knowledge, speaker’s intention, etc., determines the referent of N. (6) All names have their own referents, including physical individuals, and parasitic, fictional, or intensional objects; there are few names absolutely without reference
2016 Archaeological Investigations at the T. M. Sanders Site (41LR2), Lamar County, Texas
No full textOn March 4th and 5th, 2016, Bo Nelson and Mark Walters returned to the T. M. Sanders site (41LR2) to inspect the property after Julia Trigg Crawford, the main landowner of the site, informed us that the fields at the site had been prepped for this year ’s planting. This article summarizes the findings from these archaeological investigations, which also included the surface examination of the 40 acres of the Sanders site owned by the Sanders family.
The Sanders site is a large and impressive ancestral Caddo mound center and village situated on an alluvial terrace (450 ft. amsl) at the mouth of Bois d’Arc Creek and the Red River (Figure 1). The Sanders site was first investigated by archaeologists from the University of Texas in 1931 (Chelf 1939; Jackson 2000; Jackson et al. 2000; Krieger 1946, 2000; Pearce and Jackson 1931), where the work concentrated on the excavation of a number of burial features in Mound No. 1 or the East Mound, the trenching of Mound No. 2 or the West Mound, and the trenching of thick midden deposits that were present between the two mounds. The collections from this work are at the Texas Archeological Research Laboratory at The University of Texas at Austin. Members of the Dallas Archeological Society excavated burial features and obtained surface collections in the 1940s-1950s (Hanna 1950; Harris 1953; Housewright 1940) from the Sanders site. R. King Harris, in particular, amassed a large collection of artifacts from the Sanders site that are now held by the National Museum of Natural History at the Smithsonian Institution (Perttula et al. 2015).
Other than a number of bioarchaeological studies of the human remains from the East Mound burial features (Hamilton 1997; Maples 1962; Wilson 1993, 1994, 1995, 1997; Wilson and Cargill 1993), there were no professional archaeological investigations conducted at the Sanders site again until 2011, when survey and/or test excavations were carried out in the proposed right-of-ways for the Keystone pipeline where they crossed non-mound habitation areas (Acuna et al. 2011; Perttula and Marceaux 2011; Peyton 2013). This work renewed attention to the significance of the Caddo archaeological deposits at the Sanders site, including both mound and non-mound areas, and with the permission of the Crawford family and the Sanders family, periodic archaeological and geophysical investigations have been conducted across much of the 200+ acres of the Sanders site since 2013 (Perttula 2013; Perttula et al. 2014, 2015, 2016; Perttula and Nelson 2016; Walker and Perttula 2016). The 2016 work represents a continuation of this effort
Frequency-uniform decomposition method for the generalized BO, KdV and NLS equations
No full textAbstractSufficient and necessary conditions for the embeddings between Besov spaces Bp,qs1 and modulation spaces Mp,qs2 are obtained. Moreover, using the frequency-uniform decomposition method, we study the Cauchy problem for the generalized BO, KdV and NLS equations, for which the global well-posedness of solutions with the small rough data in certain modulation spaces M2,1s is shown
Spherically symmetric solution of f(R,G) gravity at low energy
No full textThe weak-field and slow-motion limit of f(R,G) gravity is developed up to (v/c)(4) order in a spherically symmetric background. Considering the Taylor expansion of a general function f around vanishing values of R and G, we present general vacuum solutions up to (v/c)(4) order for the gravitational field generated by a ball-like source. The spatial behaviors at (v/c)(2) order are the same for f(R,G) gravity and f(R) gravity, and their corresponding real valued static behaviors are presented and compared with the one in general relativity. The static Yukawa-like behavior is proved to be compatible with the previous result of the most general fourth-order theory. At (v/c)(4) order, the static corrections to the Yukawa-like behavior for f(R,G) gravity, f(R) gravity, and the Starobinsky gravity are presented and compared with the one in general relativity.National Natural Science Foundation of China [11120101004, 11475006]SCI(E)[email protected]; [email protected]
