Beam-End Bond Tests of Textured-Epoxy-Coated No. 6 Reinforcing Bars
No full textIn this study, the bond strength of No. 6 textured-epoxy-coated reinforcement (TECR)–epoxy-coated reinforcement with a texturing surface treatment material–is evaluated. The bond strength of the TECR, produced by Sherwin-Williams, is compared to that of uncoated reinforcement using beam-end tests performed in accordance with ASTM A944 and A1124 using six pairs of TECR and uncoated bar specimens. The TECR exhibited a bond strength equal to 100.3 percent of that of uncoated reinforcement from the same heat of steel. The difference in bond strength is not statistically significant. The test results can be used to develop bond qualification recommendations for reinforcing bars with textured coating to be incorporated in ASTM A1124. Based on these results, it is recommended that the required bond strength of TECR be increased from 96% to 99.5% of the bond strength of uncoated bars and that the textured coating be considered as providing bond strength equivalent to that of uncoated bars.CRSI Education & Research Foundatio
Library-coordinated institutional membership in The Carpentries: A qualitative case study (Interview questions and coding scheme)
No full textThis deposit contains the questions used during the semi-structured interviews and focus group, as well as the qualitative coding scheme. To protect participant identities, the transcripts that constitute this project's data are not shared. Any codes in the coding scheme describing potentially identifiable aspects of research participants are excluded from this shared version of the codebook.This qualitative case study seeks to answer the question, “How does Carpentries membership work inside a member institution?” The Carpentries organization teaches data and computing tools and skills to researchers. Institutions can implement a regular program of Carpentries workshops taught by local instructors by joining the Carpentries as institutional members. While the steps to becoming a member are readily available, little public information exists about operating an institutional membership. To answer this question, this case study examines the first five years of the University of Oklahoma’s institutional Carpentries membership, focusing on its membership activities, workflows, sponsorship, and value to participants. The study reveals the complexity of Carpentries membership operations and suggests takeaways for existing and potential member institutions

About the Author:
Born in Toronto of Indian and Celtic heritage, Rakesh (Raj) Kumar Bhala is a dual Canadian-U.S. citizen prominent in the fields of International Trade Law, Islamic Law (Sharī‘a), and Law and Literature. Raj is a University Distinguished Professor at the University of Kansas, School of Law (KU Law). He is published widely world-wide – authoring over 100 scholarly articles and 13 books, including the International Trade Law Textbook, which has been used at over 100 law schools around the globe. Ingram’s Business Magazine designated him as one of “50 Kansans You Should Know.”
Raj has testified before the U.K. Parliament, House of Commons, International Trade Committee, on trade and human rights. Media frequently call upon Raj. Across 65 consecutive months (from January 2017-October 2022), “On Point” was his column on International Law and Economics, which Bloomberg Quint / BQ Prime (Mumbai) published and distributed to approximately 6.2 million readers globally.
Raj is a Harvard Law School (HLS) graduate (Cum Laude). As a Marshall Scholar, Raj earned two Master’s degrees, from the London School of Economics (LSE) in Economics, and from Oxford (Trinity College) in Management (Industrial Relations). His undergraduate degree is from Duke (Summa Cum Laude, Phi Beta Kappa), where he was an Angier B. Duke Scholar and double-majored in Economics and Sociology. After HLS, Raj practiced at the Federal Reserve Bank of New York, where he twice won the President’s Award for Excellence thanks to his service as a delegate to the United Nations Conference on International Trade Law (UNCITRAL), along with a Letter of Commendation from the U.S. Department of State. He is a member of the State Department’s Speaker Program.
Raj has served in officer positions at the International Bar Association (IBA) and Inter-Pacific Bar Association (IPBA), on the Executive Board of Directors of the Carriage Club of Kansas City (including as Treasurer), and been on the Alumni Association Board of the University School of Milwaukee (USM), his high school alma mater. He is grateful to his USM teachers for a liberal arts education that made all good things possible. Raj loves fitness training, has finished 115 marathons, including the “Big Five” of the “World’s Majors” (Boston twice, New York twice, Chicago twice, Berlin, and London). He enjoys studying Shakespeare and (especially since becoming Catholic at Easter Vigil 2001) Theology – and watching baseball.Volume Three, Customs Law, is about a (maybe the) “bread-and-butter” specialty within International Trade Law, namely, the clearance of merchandise exported from one country into the customs territory of another country. Every article of merchandise shipped across an international boundary must satisfy the customs rules of the importing country. Though the GATT-WTO regime contains treaties on Customs Law, most of the key rules are at the national level. So, the focus of this Volume is on U.S. Customs Law. As the dominant player in world trade, and the one with the most sophisticated set of customs rules dating to the founding of the American Republic, that focus is the most influential example.
Part One deals with the answer to an obvious question: how is it known whether a good is “foreign,” and thus being imported? The answer is a Rule of Origin. That answer belies the complexity of identifying and applying the correct ROO for a shipment of merchandise. This Part, however, expounds on the different conceptual types of ROOs, and how they are employed in practice. And, this Part explains that once the proper ROO is identified and applied, country-of-origin labelling rules may be triggered. That’s because it is U.S. Customs Law that every article of foreign-origin merchandise (or, in some cases, its container) must be accurately, legibly labelled with the country in which that merchandise originated.
Part Two deals with the answer to a non-obvious question: what options exist for bringing merchandise into an importing country? Most merchandise is entered for consumption, but there are other possibilities. Warehouses and FTZs are among the leading alternatives, and afford importers and exporters alike transactional and strategic flexibility.
Parts Three and Four deal with the heart of the customs clearance process – classification and valuation, respectively. Tariff liability owed by an importer of record depends on the proper classification of merchandise in the Harmonized Tariff Schedule, which yields an applied duty rate, multiplied by the value of the product, which thus yields a specific tariff figure. Both processes, classification and valuation, are zero-sum games: importers seek to minimize their tariff liability, while governmental customs authorities, like U.S. CBP, wish to maximize tariff revenue. The games are refereed, as it were, by rules on product classification, such as the GRI, and on methodologies for valuation. These rules and methodologies, along with the vast U.S. case law on them, and how to read a Tariff Schedule, are covered in this Part.
Finally, Part Five summarizes special Customs Law programs under U.S. Customs law. One program, drawback, allows importers to be refunded certain tariffs on inputs they previously paid, when finished merchandise is exported. A second program, pre-shipment inspection, can help speed up the customs clearance process by taking care of necessary checks in the exporting country. PSI can be especially helpful to developing and least developed countries, ensuring their merchandise – including perishable products – are not held up at entry ports in developed countries because they fail the checks. Likewise, poor countries can benefit from trade facilitation and the possibilities afforded by the WTO

Textured Epoxy-Coated Hooked Bars
No full textThese are the slides from a presentation given at ACI Concrete Convention on 03/30/2025.The ACI Building Code and AASHTO Bridge Specifications require the development lengths of epoxy-coated hooked bars to be 20 percent longer than for uncoated bars. A new textured epoxy coating produced by Sherwin-Williams provides corrosion protection along with improved bond strength and damage tolerance. Tests have demonstrated that the bond strength of straight textured epoxy-coated reinforcement (TECR) satisfying ASTM A1124 is equivalent to the bond strength of uncoated bars. Tests are now underway to compare the anchorage strengths of textured epoxy-coated and uncoated hooked bars that may permit the use of a coating factor of 1.0 for both within the ACI Building Code and the AASHTO Bridge Specifications. This study examines the bond strength of TECR using beam-end specimens, as required by ASTM A1124, and the anchorage strength of hooked TECR using simulated beam-column joint specimens. To date, 12 beam-end specimens - six pairs of TECR and uncoated bar specimens - were tested in accordance with ASTM A944 and A1124, and one pair of simulated beam column joint specimens containing TECR and uncoated No. 11 bars, embedded at 22 in. with a concrete compressive strength of 5000 psi, was tested. Figures 1 and 2 show the test setups for the beam-end specimens and the simulated beam column joint specimens, respectively. The TECR exhibited a bond strength equal to 100.3 percent of that of uncoated reinforcement from the same heat of steel in the beam-end test. Similarly, the TECR exhibited an anchorage strength equal to 107.3 percent of that of uncoated reinforcement in the simulated beam column specimen test. Additional tests are planned and will be reported
Terrorism and Voting Behavior: The case of Türkiye
No full textThese are the slides from a presentation given at MPSA on 04/11/2025.The literature suggests that terrorist activities have a significant effect on the voting attitudes of people. The growing body of studies suggested that terrorism has a positive effect on incumbent parties or hard-liners. However, the analyses were mostly limited to the district level. This research paper empirically analyzes the effect of terrorist activities on the voting behavior of Turkish citizens in the 2023 general election. A unique dataset is created that focuses on the funeral ceremonies of security officers at the sub-ward level (ilçe, belde, köy, mahalle) one year prior to the 2023 general election. The dataset provides a unique chance to analyze whether or not the deaths of members of security forces cause volatility over general elections at a sub-ward level. I hypothesized that a higher number of deaths increases volatility in the sub-ward level. The research paper aims to provide critical insights by focusing on deaths and their effect on volatility in Turkiye.
This paper empirically analyzes how terrorism affects voting behavior in Turkiye on a sub-ward level. A unique dataset is created based on the burial grounds of security forces who were killed six months prior to the 2023 general election
Type-I and type-II interfaces in a MoSe2/WS2 van der Waals heterostructure (Dataset)
No full textWe report experimental evidence that MoSe2 and WS2 allows the formation of type-I and type-II interfaces, according to the thickness of the former. Heterostructure samples are obtained by stacking a monolayer WS2 flake on top of a MoSe2 flake that contains regions of thickness from 1 to 4 layers. Photoluminescence spectroscopy and transient absorption measurements reveal a type-II interface in the regions of monolayer MoSe2 in contact with monolayer WS2. In other regions of the heterostructure formed by multilayer MoSe2 and monolayer WS2, features of type-I interface are observed, including the absence of charge transfer and dominance of intralayer excitons in MoSe2. Coexistence of type-I and type-II interfaces in a single heterostructure offers opportunities to design sophisticated two-dimensional materials with finely controlled photocarrier behaviors
The Hottest Ticket in the City! A Look at the Dew Drop Inn
No full textThis poster was presented at National Council on Public History on 03/27/2025.The Dew Drop Inn in New Orleans, LA, offers an impressive case study in economic resilience and social justice through community engagement and historical preservation. Established in 1939, the Dew Drop became a cornerstone of Black culture and Queer performance during the Jim Crow era. As one of the few Black-owned hotels in New Orleans, it was a vibrant hub for top entertainers and a crucial gathering place for the community. It embodied the resilience and spirit of Black New Orleanians cultivating a sound that would later become known as Rhythm and Blues.
Previously known as “the South’s swankiest spot”, in the 50’s and 60’s the place was known for hosting top acts like Ray Charles, Little Richard, Fats Domino, and more. During its original opening it served as a barbershop, nightclub, restaurant, and hotel in addition it was also featured in the notorious Green Book.
Today it is the only Black owned museum-hotel in Louisiana—showcasing a unique model of integrating historical preservation with contemporary community needs.
The Dew Drop Inn Hotel epitomizes the intersection of Black history, community activism, and innovative museum practices. This case study illustrates how historical preservation and community engagement can create dynamic experiences that honor the past while addressing contemporary needs. This research underscores the importance of preserving spaces where minority communities connect with their history and influence their present, paving the way for a more inclusive and vibrant future in historical spaces
Influence of Parental Anxiety on Child Performance on the Behavioral Approach Task: Comparing Outcomes With and Without Parental Presence
No full textThis poster was presented at Anxiety and Depression Association of America on 04/04/2025.Clinical anxiety occurs in 10-20% of youth, with specific phobia considered the leading anxiety disorder in children (Merikangas et al., 2010). Anxiety disorders lead to significant impairment and predict a chronic course of psychiatric conditions later in life (Bittner et al., 2007). Evidence suggests that parenting behaviors and parental psychopathology contribute to the maintenance and exacerbation of child anxiety. In particular, parental anxiety may be indirectly transferred to children through specific parenting practices (e.g., overcontrol, accommodation) and can lead to worsened anxiety outcomes (Kerns et al., 2017; Ollendick & Horsch, 2007). This can be studied in a lab setting using the Behavioral Approach Task (BAT) to capture behavioral avoidance associated with specific phobias. In an attempt to replicate past work in a larger sample (Ollendick et al., 2012), this study aimed to investigate the impact of parent phobic and general anxiety on the BAT performance of phobic children. It was hypothesized that parental general and phobic anxiety would be related to worse child BAT performance, but only when parents were present during the BAT. Youth (n=125, Mage=8.86, 50.4% Female, 88% White) with a specific phobia completed two BATs: one with a parent present and one without (Öst et al., 2001). Both BATs required them to approach their specific phobic stimulus/situation. Child performance was measured by the Subjective Units of Distress (SUDS) rating at the last step of the BATs (when the BAT was completed or when youth indicated that they wished to stop) and percent steps completed (% steps) on the BAT. Parents (n=125, 76% mothers) completed a self-report measure of psychopathology [Brief Symptom Inventory (BSI); Derogatis, 1975] and the phobic and general anxiety subscales were used. Four repeated measures analyses of variance were conducted to examine the effects of parental presence and its interaction with both parent general and phobic anxiety on SUDS and % steps during the BATs. Findings revealed a significant main effect of parental presence on both SUDS, Wilks’ Λ=0.724, F(1, 120)=45.73, p<.001, partial η²=.276, and % steps, Wilks’ Λ= 0.724, F(1, 120) = 45.69, p < .001, partial η² = .276. Children’s SUDS ratings were 1.726 units lower and they completed 19% more steps when their parents was present during the BAT, compared to when they completed it alone., However, the interactions between parental presence and both phobic and general parental anxiety were not significant for SUDS (p = .759, p = .504) or % steps (p = .34, p = .31). This study highlights the significant impact of parental presence on phobia child performance during a Behavioral Approach Task, with children reporting lower distress and completing more steps when their parent was present compared to when they were alone. However, our hypotheses that parental phobic and general anxiety would moderate these effects were not supported, suggesting that the mere presence of a parent, regardless of their anxiety level, may decrease a child’s behavioral avoidance and distress during anxiety-provoking situations. It may be that overall anxiety levels of parents in this study were too low to negatively impact child performance and results may be different in a sample of clinically anxious parents. Alternatively, it may be that general parental anxiety is not a good predictor of parent behavior during a specific task. Future work should assess the impact of state-level parent anxiety during the BAT, or measure parenting behavior directly
Truth and Democratic Accountability: Considerations for the Public Sphere, Public Leadership and Performance Management
No full textThis essay draws on the extensive legacy of political philosophy to examine the relationship between truth and the administration of liberal democracies. The essay includes a discussion of the relationship between truth and the “reason” of classical, small ‘l’ liberalism, the role of science as an institution and a generator of truth claims, and differences between truth and opinions in relation to political discourse. Contemporary challenges with truthfulness in liberal democracies are explored, including the role of postmodernism and the current climate of conspiracy, conflation of truth claims and opinions, and organized lying. The essay looks at the ways that truth and public accountably can be reclaimed in the public sphere, calling for a renewed focus on the ethics of public leadership, and inviting the reconsideration of the narrative functions of performance management systems. The essay concludes with a call for public accountability scholars to consider the basis of truthfulness as a metastandard for democratic accountability
