Archaeological Investigations of Three Historic House Sites in HemisFair Park
(Center for Archaeological Research, The University of Texas at San Antonio, 2024-07-22) McKenzie, Clinton M. M.; Burns, David; Wall, Peggy
Between August 2022 and October 2023, the Center for Archaeological Research (CAR) monitored grading, utility trenching, and foundation pier drilling for the redevelopment of the former site of the Huebaum House and the adjacent Espinosa House in HemisFair Park, San Antonio. CAR performed the work on behalf of the Project Sponsor, Sprinkle & Company. The City of San Antonio (COSA) owns the property. Compliance with the Texas Antiquities Code and the Unified Development Code of the COSA (Article 6 35-630 to 35-634) was therefore required. CAR conducted this work under Texas Antiquities Permit (TAP) Number 30745, issued to David Yelacic, former CAR Director, who served as the initial Principal Investigator (PI). The permit was later transferred to Cynthia Muñoz, CAR Director, who served as PI for the completion of the report writing. The project area covered 1.2 hectares (0.298 acres). It fronts on the west side of HemisFair Boulevard, including the addresses 603, 607 and 611, north of the intersection with E. Cesar Chavez. The lot at 603 was vacant at the time the project started, but was the former site of Huebaum House, 41BX982. The 603 lot saw the greatest impact as a part of the Sprinkle Co.’s redevelopment work. Impacts were also made to the side and front of 607, the extant historic Espinosa house, 41BX593. The work also included excavations along the front and a portion of the north side of the CommonWealth Coffee House and Bakery, addressed at 611. The establishment is located within the historic Koehler House, 41BX592. Both extant historic structures are designated State Antiquities Landmarks (SALs) and listed on the National Register of Historic Places (NRHP). The CAR monitored all excavations within the project boundary which included backhoe trenching for utility installation and landscaping, and auguring using a skid-steer with a mechanical auger for the installation of foundation piers. CAR found five features, one on the Koehler House Site, one on the Espinosa House Site, and three on the Huebaum House Site. The Koehler House Site feature was infrastructure associated with the 1965-1968 development work for HemisFair (Feature 1). A late nineteenth to early twentieth century historic sidewalk at an angle to the front walk of the Espinosa House was designated as Feature 5. The three features found on the Huebaum House Site included remnants of the north and south exterior limestone wall foundations, designated Features 3 and 4, and a sub-floor foundation contemporaneous with the original construction composed of a slurry of limestone, mortar and caliche, designated Feature 2. Additionally, sparse historic artifacts were collected from the spoil during the process of the excavations, including cut and extruded wire nails, mid-to-late nineteenth century ceramic sherds, and pieces of historic glass. No distinct artifact deposits were noted or warranted designation as features. All project related materials, including the final report, are permanently stored at the CAR facilities in accession file number 2878. The production of the archival and historical portion of the report resulted in the identification of several misleading or erroneous citations and related attributions to two of the three trinomials investigated. The research also found that 41BX982, the Huebaum House, was not correctly plotted on the Sites Atlas. These identified deficiencies are fully described in Chapter 3. As a result of these prior errors, CAR recommends that the name of the Koehler House be revised to Koehler Rent House and that the Sites Atlas entries for the Koehler Rent House and for the Huebaum House be revised to match correct attribution terms, geographic placement, and correct citations. Five separate archaeological investigations, including the present undertaking, have occurred that have involved these three sites (Cox 1985; Fox and Cox 1999; Cox 1992a; Zapata et al. 2018). Both the amount and geographic scale of excavations, archival research and analysis of the results show that there is limited, if any, research potential remaining relative to the three residential trinomials. For this reason, CAR recommends that no further subsurface monitoring be required for future work on any of these three sites. CAR does not include the Acequia Madre de Valero, 41BX8, which forms the western/northwestern property line of the three lots for 41BX592, 593 and 982, as a part of that recommendation. This irrigation canal dates to the first quarter of the eighteenth century and had a use life extending to 1905-1906. CAR recommends that, at a minimum, a 4.5 m buffer be maintained, centered on the mid-line of the acequia channel eastward/southeastward into each adjoining lot. CAR recommends that any work undertaken on these properties that fall within the buffer would require archaeological monitoring.
Plasma-Assisted One-Step Direct Methanol Conversion to Ethylene Glycol and Hydrogen: Process Intensification
(2024-06-29) Ayodele, Olumide Bolarinwa
This perspective reports a process intensification strategy that converts methanol into ethylene glycol (MeOH-2-EG) in a single step to circumvent multi-step naphtha cracking into ethylene followed by ethylene epoxidation to ethylene oxide (EO) and the subsequent hydrolysis of EO to ethylene glycol (EG). Due to the thermodynamic restriction for the direct MeOH-2-EG, plasma-assisted catalysis was introduced, and platinum group metals were identified as prospective transition metal catalysts that can achieve the formation of strong metal hydride bonds and guarantee the controlled C–C coupling of two plasma-activated hydroxymethyl radicals (*CH2OH) from methanol, both of which are essential for the single-step MeOH-2-EG.
Archaeological Investigation of the Upper Labor Acequia, San Antonio, Bexar County, Texas
(Center for Archaeological Research, The University of Texas at San Antonio, 2024-07-03) Kemp, Leonard
The Center for Archaeological Research (CAR) conducted an archaeological investigation of a section of the Upper Labor Acequia (ULA; 41BX2043) in Brackenridge Park, San Antonio, Texas. The work was in response to a request from the City of San Antonio (COSA) Public Works Department to provide information to the structural engineer for future remediation of the acequia. The project area is also within a previously designated site, 41BX1425 described as a large prehistoric campsite. The ULA is a contributing element to the Brackenridge Park National Register District and is also listed as a State Antiquities Landmark. The work described here was conducted under Texas Antiquities Permit (TAP) 31262, with Cynthia Munoz serving as the Principal Investigator. The investigation, conducted in July 2023 and January 2024, included the excavation of three trenches to describe the exterior wall of the acequia and three test units to describe the interior wall of the acequia. In general, the acequia in the project area has been impacted, to varying degrees, as evidenced by highly fragmented wall sections, collapsing wall sections, missing stone, and/or wall sections with cracks. Trenching revealed that the exterior wall is comprised of stacked limestone rubble and larger stone that is not mortared. The interior of the wall consists of a mortared limestone facade. The foundation of the interior wall is limestone rubble resting on a clay matrix. No definitive acequia channel floor was found during the excavation. The test unit excavations within the acequia recovered modern debris, although a single flake was observed in the spoil pile of one of the test units. All three external trenches contained prehistoric artifacts, including debitage and/or burned rock. The CAR documented an amorphous, ashy deposit in the floor of Trench 2 at approximately 80 cm below the top of the acequia wall. Designated Feature 1, it included burned earth, burned clay, ash, charcoal, and two burned rocks. The feature covers an area roughly 50 by 30 cm, with an unknown depth. A radiocarbon date on charcoal extracted from a sediment sample collected from the feature yielded a median date of 1306 cal BP with a two-sigma range of from 1345 to 1291 cal BP, documenting an occupation at the end of the Late Archaic Period. A burned rock cluster and a single flake was present in the western wall of the trench, roughly 30 cm above where the feature was defined. While the association of this material with Feature 1 is not clear, it is the case that an unknown portion of the feature was removed by the backhoe prior to the feature identification. Burned rock and debitage were also observed in Trench 1. Trench 3 contained these materials as well as faunal bone. Following the trench and test unit excavations the structural engineer, Shawn Franke, P.E., the City Archaeologist Matthew Elverson, and the THC’s Dr. Emily Dylla reviewed the exposed portion of the ULA. Given the recovery during this investigation of cultural material and an archaeological feature with chronological information and integrity, CAR recommends that the deposits adjacent to the acequia on site 41BX1425 are eligible for listing on the National Register of Historic Places (NRHP) under criterion D, in that the deposits have yielded, and are likely to yield, information important to prehistory. In addition, the CAR recommends that this area of the site is eligible for designation as a State Antiquities Landmark (SAL) in that the site has the potential to contribute new and important information and thereby lead to a better understanding of Texas prehistory. Given that recommendation, and our current understanding of the proposed work, the CAR further recommends the development of a proactive testing program to mitigate impacts to this area of the site. CAR will submit a site update (41BX1425) of this recent investigation to the Texas Archaeological Sites Atlas following comments by the COSA Office of Historic Preservation (OHP) and the Texas Historical Commission (THC), along with a GIS shapefile of the site and other information relevant to TAP No. 31262. Following completion of the fieldwork, all project-related materials, including the final report, were permanently stored at the CAR’s curation facility under accession number 2868.
Size Matters? Penis Dissatisfaction and Gun Ownership in America
(SAGE Publications, 2024-05-31) Hill, Terrence D.; Zeng, Liwen; Burdette, Amy M.; Dowd-Arrow, Benjamin; Bartkowski, John P.; Ellison, Christopher G.
In this study, we formally examine the association between penis size dissatisfaction and gun ownership in America. The primary hypothesis, derived from the psychosexual theory of gun ownership, asserts that men who are more dissatisfied with the size of their penises will be more likely to personally own guns. To test this hypothesis, we used data collected from the 2023 Masculinity, Sexual Health, and Politics (MSHAP) survey, a national probability sample of 1,840 men, and regression analyses to model personal gun ownership as a function of penis size dissatisfaction, experiences with penis enlargement, social desirability, masculinity, body mass, mental health, and a range of sociodemographic characteristics. We find that men who are more dissatisfied with the size of their penises are less likely to personally own guns across outcomes, including any gun ownership, military-style rifle ownership, and total number of guns owned. The inverse association between penis size dissatisfaction and gun ownership is linear; however, the association is weakest among men ages 60 and older. With these findings in mind, we failed to observe any differences in personal gun ownership between men who have and have not attempted penis enlargement. To our knowledge, this is the first study to formally examine the association between penis size and personal gun ownership in America. Our findings fail to support the psychosexual theory of gun ownership. Alternative theories are posited for the apparent inverse association between penis size dissatisfaction and personal gun ownership, including higher levels of testosterone and constructionist explanations.
Dealing with the social-emotional effects of the COVID-19 pandemic: School administrators’ leadership experiences in Texas, USA
(SAGE Publications, 2024-05-22) Okilwa, Nathern S. A.; Barnett, Bruce
The onset of COVID-19 in March 2020 presented unprecedented disruption to the education systems across the globe. Given that school leaders were at the forefront of guiding schools during the tumultuous times, the purpose of this article is to highlight the aftereffects of the COVID-19 pandemic on schools and examine how school leaders addressed these challenges, particularly the lingering social-emotional disruptions the students and teachers are experiencing. This qualitative study utilized an online survey to collect the perspectives of South Texas school leaders on the challenging circumstances of the COVID-19 pandemic. The findings are organized by: leadership experiences during the COVID-19 pandemic (lessons learned and critical practices), additional knowledge and skills (social-emotional well-being, resources to address social-emotional well-being, and parental engagement), and suggestions for preparation programs (students’ social-emotional learning (SEL) and teachers’ well-being). The scale of emerging pandemic-related challenges has left school leaders scrambling to seek innovative approaches to maintain a safe and orderly teaching and learning environment. Implementing SEL for students and educators seems to hold promise.
