Processed vs unprocessed collection--what's the difference?
A processed collection has gone through several steps to become a cataloged record, thus available to the researching public. Those steps include a thorough vetting of copyright and restrictions, a verbatim transcription or thorough indexing of the interview including time-stamped calibration, the opportunity for the interviewee to review the transcription, the creation of a finding aid that includes important metadata about the collection, the preservation and optimization of audio files, the creation of user-copies, and cataloging. This process requires the efforts of several LSU Libraries staff members and it has been calculated that for every hour of recording, it takes 35-50 hours to fully process. For a detailed breakdown of the stages and fees associated with archiving oral histories, please see The Oral History Budget. All processed collections are found in the catalog record and many are available on the Louisiana Digital Library. An unprocessed collection is one that has not reached the final stage of completion and is not yet ready to be cataloged. Depending on the stage of processing, more or less of the interview will be available to patrons. See below for the availability of unprocessed collections. An unprocessed collection is not in the catalog record nor the Louisiana Digital Library.

What are Special Collections?
Special collections refer to unique materials that provide both primary and secondary sources to people conducting original research. Our collections are special due to their scarcity or rarity, historical value, monetary value, or research value. Archives are collections of original records created throughout the lifespan of a person, family, organization, or business. These materials essentially provide evidence of the activities, events, functions, and/or responsibilities of the creator(s). Archives and special collections differ from libraries in the types of materials collected and the ways in which they are acquired, organized, described, and made publicly accessible. These differences prompt us to create specific policies and procedures to ensure that our collections can continue to be used for decades or even centuries to come.

Catch Me If You Can: A Multi-Agent Synthetic Fraud Detection Framework for Complex Networks
Detecting fraudulent behavior across diverse domains presents a significant challenge due to the adaptive and elusive activities of fraud agents. Furthermore, imbalanced data distributions and limited labeled examples increase the difficulty of detecting fraud agents. To address these challenges, we propose Catch Me If You Can—a Multi-Agent Framework to generate synthetic datasets and simulate various types of fraudulent behavior, including but not limited to anti-money laundering (AML), credit card fraud, bot attacks, and malicious traffic. Our framework comprises two core agent types: (1) Detectors, trained to identify suspicious patterns in scenarios, and (2) Transaction Agents, including both legitimate participants and adversarial fraud agents employing strategies to evade detection. In this framework, detectors iteratively refine their detection strategies while fraud agents evolve adaptive tactics to disguise illicit activities, creating an adversarial coevolutionary environment. This dynamic fosters the generation of high-dimensional and realistic datasets for training and testing. By integrating synthetic pre-training with transfer learning, the framework leverages a variety of real-world datasets—including IEEE-CIS Fraud Detection, Credit Card Fraud Detection, and Elliptic++—demonstrating its broad applicability across multiple fraud domains. Our approach significantly improves detection performance, bridging the gap between simulation and real-world applications. It enables robust training across heterogeneous fraud behaviors, contributing to the development of resilient, generalizable solutions for financial security and fraud prevention.
“They Had to Catch Me Like an Animal” : Exploring Experiences of Involuntary Care for People with Psychosocial Conditions in South Africa
Protecting the rights of people with psychosocial conditions is an important and controversial global aim, particularly in light of multiple calls for reduced coercion catalyzed by General Comment 1 of the United Nations Committee on the Rights of Persons with Disabilities, which stipulates the replacement of substituted care with supported care. Responding to this and other global calls for reduced coercion is complex globally but can entail particular challenges in developing countries, where resource shortages and environmental barriers are sometimes a significant factor in how people with mental conditions experience involuntary care and encounter limitations to their autonomy. To better understand these complexities, our study explored experiences of involuntary care among people with psychosocial conditions in South Africa. Participants described varying degrees of coercion within involuntary care and found that different approaches from professionals when they were in crisis significantly impacted their illness experience, including their ability to make decisions and feel dignified. Participants’ reports include variable feelings and embodied experiences of coercion in different forms and degrees, ambivalence about compliance and resistance while being treated against their will, and gray areas between conventional separations of autonomy and paternalism. On the whole, our analysis troubles binaries about the use or disuse of involuntary care and illustrates the complexity of participants’ experiences and views of coercive intervention, which could hold multiple possibilities for both care and autonomy.
Executive functions and associated brain volumetry in children with persistent stunting and catch-up growth
Early childhood stunting can result in sub-optimal executive functions (EF), affecting academic achievements and economic potential in later life. This study hypothesized that children always stunted (AS) at ages 2, 5 and 9 years had lower EF than those who were never stunted (NS). A birth-cohort in Vellore, India was followed up with periodic anthropometric and development/cognitive measures over 2, 5 and 9 years of age. Based on stunting status at these time points, children were classified as NS, stunted at 2 years and caught up by 5 years (S2N5), stunted at 2 and 5 years but caught up later (S5N9), and AS. At 9th year, children underwent neuroimaging using 3T MRI scanner and EF assessment using FAS phonemic fluency test, colour cancellation test and colour trials tests (CTT). From the original birth-cohort of 251, 205 children were reviewed at 9 years. FAS phonemic fluency test showed NS group had significantly higher test scores compared to AS (11.52 vs. 7.4, p = 0.02). In CTT, a significant difference in near misses score was observed between NS and AS groups (0.12 vs. 0.38, p = 0.03). Upon evaluating unimodal brain association areas, volumes of right occipital fusiform gyrus (9991 mm3 vs. 9313 mm3; p = 0.04; η2 = 0.11), and left lateral occipital cortex (13458 mm3 vs. 12559 mm3; p = 0.03; η2 = 0.07) were significantly higher among NS compared to AS group. Considering higher order association areas, only left pars triangularis was found to be significantly reduced among AS children compared to NS group (4284 mm3 vs. 3291 mm3; p = 0.01; η2 = 0.07). Similarly, there were also significance visible in the basal ganglia regions and the cerebellum. Current study demonstrated EF dysfunction in verbal fluency and inhibitory control in a dose response fashion in groups AS-to-NS with corresponding EF-related brain volumetric changes, highlighting the need for focused nutritional and nurturing approaches in early childhood for gain in human capital.
