Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Pedestrian survey and NRHP eligibility testing of sites within a proposed detention facility in Webb County, Texas
No full textThe Center for Archaeological Research (CAR) of The University of Texas at San Antonio was contracted by MACTEC Engineering & Consulting, Inc. (hereafter, MACTEC) to perform Phase I archaeological survey and Phase II testing prior to the construction of a detention facility in Webb County, Texas. Section 106 of the National Historic Preservation Act (NHPA) requires federal agencies to take into consideration the effects of proposed undertakings on cultural resources within the Area of Potential Effect (APE). While the proposed undertaking is being developed by The GEOGroup, Inc. on privately owned property and is funded by private resources, the anticipated use of the facility by the United States Marshals Service makes this project a federal undertaking as defined under 36 CFR part 800.16(y). As such, the project must comply with Section 106 of the NHPA. The Texas Historical Commission (THC) is the reviewing agency for the project. In December, 2004, CAR conducted an intensive survey of the APE for the proposed construction of the detention facility. The survey followed MACTEC's preliminary cultural resources assessment and included pedestrian survey with shovel testing within an approximate 160-acre tract, and backhoe trenching of selected locations within the approximate 30-acre APE of the proposed undertaking. Eleven field sites were defined as a result of the intensive survey (Field Site 1 [41WB634], Field Site 2, Field Site 3 [41WB636], and Field Sites 4-11). Subsequently, Phase II investigations were conducted by CAR to evaluate National Register of Historic Places (NRHP) eligibility and State Archeological Landmark (SAL) designation for eight of the originally identified field sites (numbers 2 and 5-11). The Phase II investigations included the hand excavation of test units as well as mechanical auger testing. Based on the combined results of the Phase I survey and Phase II investigations, seven sites were reported to the Texas Archeological Research Laboratory and assigned trinomials (41WB634 through 41WB640). Site 41WB639 was identified as containing archaeological components with significant research potential and therefore is recommended eligible for nomination to the NRHP and for formal designation as a SAL. The site contains a Middle Archaic component buried between 100 cm and 130 cm below surface that may yield information on a regional level. Based on the findings within the proposed project area, the site is interpreted as eligible for listing in the NRHP under Criterion D. Likewise, the site is interpreted as having the potential to contribute to a better understanding of the prehistory of Texas, and therefore eligible for SAL designation based on Criterion 1. Given the depth of the component and the shallow nature of the anticipated disturbances in the vicinity of the site (two feet or about 60 cm below surface), no construction impact is likely to effect the buried component and no further work is recommended at the site. However, in the case that construction parameters are changed and anticipated impacts reach below two feet (60cm) in depth, data recovery efforts are recommended at the site. In addition, site 41WB634 was identified during the survey as having some research potential, although the NRHP and SAL eligibility of the site has not been determined. According to present construction plans, the site falls outside of the facilities footprint and will not be disturbed by construction activities. No additional archaeological investigations are recommended at the present time. The site contains a temporally unassigned, shallowly buried (10-50 cm below surface) archaeological component. If at a future date the facilities footprint is relocated or hitherto unanticipated subsurface disturbances are planned in the vicinity of this site, Phase II testing is recommended to establish the NRHP eligibility of the site. Finally, archaeological components buried at a depth of 70 cm below surface or deeper have been identified at sites 41WB637, 41WB638, and 41WB639. The NRHP/SAL eligibility of these deposits has not been fully assessed. However, the impacts of activities above these sites will consist of the planting of a grass cover and will otherwise be limited to foot traffic and therefore will be consistent with the guidelines set in the Intentional Burial of Sites as defined by the Texas Historical Commission. Therefore, no adverse affects will come to the deeply buried deposits at sites 41WB637, 41WB638 and 41WB639. The cultural materials recovered during these investigations were processed at the CAR laboratory. Following analysis, several artifact classes possessing little scientific values were discarded in consultation with MACTEC and the landowner. These artifact classes included snail shells, unburned rocks, heat spalls, modern glass, plastic, and unidentified metal fragments. In all instances, discarded materials were documented and their counts included in the report and curation documentation. All data was entered into Access and Excel spreadsheets, and copies of electronic and paper records were submitted to the client. All artifacts, including human remains, were returned to the landowner and all copies of project records are permanently curated at the Center for Archaeological Research.MACTEC Engineering and Consulting, Inc
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
National Register of Historic Places Eligibility Testing of 41WN120 at the Helton San Antonio River Nature Park in Wilson County, Texas
No full textFrom January 18 through January 31, 2011 the Center for Archaeological Research (CAR) of the University of Texas at San Antonio (UTSA) conducted limited eligibility testing at 41WN120. The site was previously identified during a 2010 intense pedestrian archaeological survey of the proposed Helton San Antonio River Nature Park located near Floresville, in Wilson County, Texas (Munoz 2010). The site is on land that is slated for phased in park improvements. The construction of a park road, a turnaround, a pavilion, and a nature center will impact the southwestern portion of 41WN120, an area identified in the 2010 survey as containing a high-density of buried cultural materials. The testing, conducted under the requirements of the Texas Antiquities Code, was performed under Texas Antiquities Permit No. 5854, with Dr. Steve Tomka serving as Principal Investigator and Cynthia Moore Munoz serving as Project Archaeologist. The work was conducted in advance of the proposed improvements. The testing involved mechanical backhoe trenching, hand auger boring, and the hand excavation of a limited number of test units. Testing confirmed that the southwestern portion of 41WN120, located along a bluff overlooking Calaveras Creek, contains a high-density of cultural material. The site consists of two broad temporal components. The upper component produced one temporally diagnostic artifact, a Marcos point, dating the component to the Late Archaic period. The lower component contained three diagnostics, an Early Triangular point, an Angostura point, and a Guadalupe tool, associating the component with the Early Archaic period. One radiocarbon date, obtained from a piece of isolated charcoal in the upper portion of the lower component confirmed this time designation. No features were encountered but burned rock was collected from throughout the components suggesting the presence of buried thermal features. A detailed debitage and tool analysis suggests that the excavated lithic material from the lower component represents late stage reduction focusing on tool production. The high density of cultural materials, burned rock suggesting buried thermal features, intact sediments, diagnostic artifacts in good context in conjunction with a radiocarbon date, and the depth of buried prehistoric material suggest that the southwest portion of 41WN120, near the bluff, possesses high potential for future research. It is the CAR’s assessment that the integrity of deposits dating to the Early Archaic occupation of 41WN120 is good. The CAR recommends that the portion of 41WN120 with high-density cultural material be listed as eligible for the National Register of Historic Places (NRHP) under criterion D of 36CRF 60.4, in that the site has and is likely to yield information significant in prehistory. The CAR also recommends listing as a State Archaeological Landmark (SAL) under criterion 1, 2, and 3 of 13TAC26.8. We recommend that this portion of 41WN120 remain off limits to any construction activities and that the San Antonio River Authority (SARA) develop a plan to protect the area. If this portion of 41WN120 cannot be avoided, then the CAR recommends the development of a plan to recover significant data from the area of high-density artifact concentration. We further recommend that the remainder of site 41WN120, the area off of the high-density artifact concentration, does not contribute to the eligibility of the site and therefore, proposed improvements may proceed as planned away from the high-density concentration. In addition to the recommendation of eligibility, as a result of the 2010 survey of the property, the CAR recommended, that the historic brick ruin adjacent to the high-density artifact area be protected (see Munoz 2010). The Texas Historic Commission (THC) and SARA agreed with the CAR’s recommendation to protect of this historic building. Following laboratory processing and analysis, and in consultation with both SARA and the THC, all burned rock, snail, and sediment samples collected on the project were discarded. This discard was in conformance with THC guidelines. All remaining archaeological samples collected by the CAR, along with all associated artifacts, documents, notes, and photographs, were prepared for curation according to THC guidelines and are permanently curated at the Center for Archaeological Research at the University of Texas at San Antonio.San Antonio River Authorit
Alazán Creek Trail System Project, San Antonio, Bexar County, Texas
No full textThe University of Texas at San Antonio Center for Archaeological Research (CAR), in response to a request from RE/SPEC Company LLC (RESPEC), conducted archaeological testing and monitoring for the Alazán Creek Trail Project. The work was completed on behalf of the San Antonio River Authority (SARA) as part of the Westside Creeks Project. Multiple federal, state, and local agencies were involved, including the United States Army Corps of Engineers (USACE), the City of San Antonio (COSA) Office of Historic Preservation (OHP), and the Texas Historical Commission (THC). The Alazán Creek Trail Project consisted of two separate components. The first component was an Alamo Area Metropolitan Planning Organization (AAMPO) and COSA trail system that extends over three miles along the Alazán Creek, beginning at Lombrano Street continuing south to just north of S. Laredo Street. This first component was in part funded by the Federal Highway Administration administered by the Texas Department of Transportation. Projects receiving federal funding must comply with Section 106 of the National Historic Preservation of 1966, as amended, and its implementing regulations, 36 Code of Federal Regulations Part 800. In addition, a Section 404 permit of the Clean Water Act was granted to RESPEC in regard to any discharge into Alazán Creek. The project was assigned Project Number SWF-2017-413. This permit required consultation between RESPEC and the USACE. The work associated with the first component included background research of the project area, a pedestrian survey, shovel testing, and backhoe trenching of a 6.1 km (3.8 mile) long segment of a multi-use trail, with a 15.2 m (50 ft.) wide easement. The total area of the APE including the trail and trailheads is 1.9 hectares (4.7 acres). This work was completed between February 2018 and April 2018. The THC granted Dr. Paul Shawn Marceaux Texas Antiquities Permit
(TAP) 8309 to conduct this component of the project.
The second component was a COSA-funded package of trailheads, connections, landscaping, and amenities to enhance the connectivity of the trail system to the surrounding neighborhoods. COSA is defined as a political subdivision under the Antiquities Code of Texas, Section 191.003(4). As such, the project was obligated to consider the impacts that it would have on known and unknown historic properties. In addition, under COSA’s Unified Development Code, Chapter 35, the city is
required to consider the impact to known or potential archaeological sites and/ or deposits and to avoid or mitigate those effects. The second component involved CAR monitoring construction for street-level trailheads and trail connectors. The second component occurred at irregular intervals between March 2020 and July 2021. THC granted Dr. Marceaux TAP 8310 to conduct this component of the project. The project archaeologist was José Zapata. Leonard Kemp stepped in as Principal Investigator upon the departure of Dr. Marceaux.
No new sites or features were recorded by CAR during the pedestrian survey, shovel testing, backhoe trenching, or monitoring. However, during mechanical grading, two large historic trash deposits were uncovered and reported to CAR by SpawGlass. CAR documented the first deposit as an early twentieth century trash midden designated 41BX2433. CAR consulted with THC and the
OHP, who allowed the contractor to proceed with construction. A search of CAR records failed to find any documentation that we consulted with the USACE concerning 41BX2433. CAR recommends that the remaining portion of 41BX2433 is eligible for inclusion to NRHP and as SAL based on Criteria D under Section 106 of the National Historic Preservation Act. The property and associated materials are likely to contribute to our knowledge of the twentieth century West Side community. CAR recommends avoidance. If this is not possible, CAR recommends that a mitigation plan be developed and implemented to gather significant data.RESPEC, Castroville, Texa
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Archaeological Backhoe Trench Excavations on the West Bank of the San Antonio River, San Antonio, Bexar County, Texas
Get PDFOn June 22, 2021, the Center for Archaeological Research (CAR) at The University of Texas at San Antonio (UTSA) conducted survey level mechanical trenching at 230 to 250 Thelka Street in the historic Beanville neighborhood in San Antonio, Bexar County, Texas. The property is located on the T2 terrace of the west bank of the San Antonio River south of the confluence of Concepcion Creek. It covers an area of less than 1 acre. The monitoring was performed in response to a request from the City of San Antonio’s Office of Historic Preservation (COSA-OHP) for archaeological investigations in advance of approving a replat of the subject property. The investigation was warranted due to the high potential for historic and prehistoric archaeological deposits. The project falls under the COSA’s Historic Preservation and Design Section of the Unified Development Code (Article 6 35-630 to 35-634). Raymond Mauldin served as Principal Investigator on the project and Clinton McKenzie served as Project Archaeologist.
Excavations at the location consisted of the intrusion of two backhoe trenches perpendicular to the San Antonio River, one on the lower terrace of the site and the second on the upper terrace. No cultural features or artifacts were encountered in the lower backhoe trench and only a thin drape of mid-twentieth century trash was encountered in the upper backhoe trench. CAR recommends that no additional work is necessary at the location. All records generated during this project were curated at the CAR in accordance with Council of Texas Archeologists (CTA) guidelines.City of San Antoni
A Cultural Resource Inventory of 550 Previously Surveyed Acres on Camp Swift, Bastrop County, Texas
No full textFrom November 2011 to January 2012, the Center for Archaeological Research (CAR) of The University of Texas at San Antonio (UTSA) conducted an intensive archaeological reconnaissance survey of 550 acres of previously surveyed land located on the Texas Military Forces’ (TXMF) Camp Swift Facility in north-central Bastrop County, Texas. The work was performed to fulfill contract requirements with the TXMF’s Adjutant General’s Office. The survey was conducted under the requirements of Section 106 and 110 of the National Historic Preservation Act (NHPA) of 1966. The survey was performed under interagency cooperation agreement TX11-ENV-09, with Dr. Steve Tomka, CAR Director, serving as Principal Investigator, Dr. Raymond Mauldin, CAR Assistant Director, serving as Project Manager, and Cynthia Moore Munoz serving as the Project Archaeologist. The work was conducted in advance of proposed improvements to the facility and in response to a large wildfire. The improvements will consist of an expansion of approximately 39 acres to an existing dropzone. Because the wildfire burned off most of the vegetation on 1,454 acres of the facility leaving high ground visibility, a resurvey of a portion of the area was also conducted. The goal of the pedestrian survey was to identify and document prehistoric and historic archaeological sites that may be impacted by the dropzone improvement or exposed and/or affected by the wildfire. This report summarizes the results of the fieldwork and provides recommendations regarding the management of cultural resources located on the project area. Pedestrian reconnaissance and 265 shovel tests were used to search for cultural resources on the 550 acre project area. Thirty-six isolated surface finds, including debitage, tools, a projectile point, a core, glass, ceramics, and a brick, were documented. Seven previously recorded sites were revisited. Ten new sites were identified during this survey. The CAR requested and was assigned trinomials (41BP859-868) for the sites. The TexSite records are on file at the Texas Archeological Research Laboratory (TARL). The ten new sites include two prehistoric surface scatters (41BP861 and 862), three prehistoric surface scatters with buried material (41BP859, 865, and 866), one buried prehistoric site with no visible surface scatter (41BP867), and four historic surface scatters (41BP860, 863, 864, and 868). Six of the ten sites (41BP860, 861, 862, 864, 867, and 868) were recommended by the CAR as not eligible for listing on the National Register of Historic Places. The remaining four sites (41BP859, 863, 865, and 866) were assessed as unknown with further investigations recommended. Following laboratory processing and analysis, and in consultation with the TXMF’s Adjutant General’s Office, all sediment samples were discarded. This discard was in conformance with Texas Historical Commission (THC) guidelines. All remaining archaeological samples collected by the CAR, along with all associated artifacts, documents, notes, and photographs, were prepared for curation according to THC guidelines and are permanently curated at TARL at the University of Texas in Austin.Texas Adjutant General's Departmen
Intensive Pedestrian Archaeological Survey of the Helton San Antonio River Nature Park, Wilson County, Texas
Get PDFDuring August 2010, The Center for Archaeological Research (CAR) of The University of Texas at San Antonio (UTSA) conducted an intensive pedestrian archaeological survey of the proposed Helton San Antonio River Nature Park located near Floresville, Texas in Wilson County to fulfill contract requirements with the San Antonio River Authority (SARA). The survey, conducted under the requirements of the Texas Antiquities Code, was performed under Texas Antiquities Permit No. 5716, with Dr. Steve A. Tomka, CAR Director, serving as Principal Investigator and Cynthia Moore Munoz and Antonia Figueroa serving as the Project Archaeologists. The work was conducted in advance of proposed improvements to the property. Multiple phased improvements proposed for the park include roads, three parking areas, hike and bike trails, scenic overlooks, picnic areas, campsites, recreational vehicle (RV) campsites, an overnight research cabin, multiple toilets and water stations, a multi-use pavilion, an environmental education center, an amphitheater, river accesses for paddling, a pond, a bridge, a riparian land management demonstration area, and a tree and native plant farm. Four existing structures on the property are planned to be used as the park headquarters building and an operations facility. The principal goal of the pedestrian survey was to identify and document all prehistoric and/or historic archaeological sites that may be impacted by the proposed improvements within the park. This report summarizes the results of the fieldwork and provides recommendations regarding the management of cultural resources located on the project area. Pedestrian reconnaissance, 100 shovel tests, 3 hand-auger tests, and 9 backhoe trenches were used to search for cultural resources on the 98 acre project area. Two new sites, 41WN120 and 41WN121, were documented within the project area. 41WN120 is a large multi-component site directly adjacent to and located on a previously plowed field on the northeastern quadrant of the project area. One diagnostic prehistoric artifact was recovered from the surface dating to the Archaic Period, several diagnostic historic artifacts dating from the late 1800s to the mid 1900s, and two structures, one constructed in the late 1800s and one in the mid 1900s, were documented on 41WN120. Subsurface cultural material was present in all levels of shovel testing of this site. Burned plant and bone was recovered off of the plowed field near the bluff adjacent to the Calaveras Creek flood plain in Level 5 (40-50 cmbs) suggesting the possibility of a subsurface hearth feature. Shovel tests in the vicinity of this location contained the deepest deposits of cultural material on the site. The results of magnetic soil susceptibility testing of sediments recovered from the site suggest two buried prehistoric surfaces. The depth of buried prehistoric material near the edge of the bluff off of the plowed area, the possibility of a buried hearth, the indications of two buried surfaces from soil susceptibility analysis, the diagnostic dart point, as well as the historic significance of the late 1800s structure suggest that 41WN120 possesses potential for future research. Therefore, the CAR recommends that the site be considered potentially eligible for listing on the National Register of Historic Places. The CAR also recommends further testing of the portion of the site containing deeply buried prehistoric material via test units and additional backhoe trenches. The CAR recommends protection of the late 1800s structure. Because the pier and beam house does not contribute to the potential eligibility of 41WN120, no further work regarding the house is necessary. 41WN121, located on a previously plowed field on the northwestern quadrant of the project area, consists of historic artifacts recovered from shovel tests (0-30 cmbs). The artifacts, including ceramics, glass, metal, and brick, suggest the site was occupied from the late 19th century into the early decades of the 20th century. The location of the artifacts in the upper 30 cm of a plowed field and lack of features indicate that 41WN121 possesses a low potential for future research. The CAR recommends that the site be considered ineligible for listing on the National Register of Historic Places. Following laboratory processing and analysis, and in consultation with both SARA and the Texas Historical Commission (THC), all burned rock and sediment samples collected on the project were discarded. This discard was in conformance with THC guidelines. All remaining archaeological samples collected by the CAR, along with all associated artifacts, documents, notes, and photographs, were prepared for curation according to THC guidelines and are permanently curated at the Center for Archaeological Research at the University of Texas at San Antonio. The CAR requested and was assigned trinomials (41WN120 and 41WN121) for the sites. The TexSite records are on file at The Texas Archeological Research Laboratory (TARL).San Antonio River Authorit
