What does bento search?

Bento searches all of the available resources at LSU Libraries. Please note that while Discovery does include Catalog results, the dedicated Catalog search can still be accessed.

Discovery
Searches our local print and electronic materials including e-books, journal articles, peer-reviewed articles, news, and magazines.
Research Guides
Searches the full-text of research guides published by LSU Libraries. A research guide is a curated, librarian‑built document that pulls together the most important resources for a topic, course, or assignment. It’s designed to help students, faculty, and researchers quickly find high‑quality, relevant information without having to sift through everything on their own.
Scholarly Repository
Searches the full-text of the Scholarly Repository. The LSU Scholarly Repository collects, preserves, publishes, and makes openly accessible the research and scholarship contributed by LSU faculty, staff, students, and units. Research and scholarly archived materials can include articles, monographs, books, theses & dissertations, audio-visual presentations, working papers, technical reports, conference proceedings, special collections, data, and publicly funded research.

Navigating the bias danger zone: Evaluating the (in)Efficiency of Linear Sequential Unmasking (LSU-E) as a bias countermeasure
Linear Sequential Unmasking (LSU-E) is a method of managing the flow of information so as to improve decision making and minimize cognitive bias in expert domains. This article examines the specific factors determining the (in)efficiency of LSU-E. Central to this evaluation is the “bias danger zone,” where decisions involve human judgement, complex data near decision thresholds, and strong directional bias. In these situations, LSU-E reduces bias by prioritizing information based on its objectivity, relevance, and biasability. However, research indicates that the sequencing of information, a core component of LSU-E, is not always effective. LSU-E's (in)efficiency depends on whether the experts perceive specific information as exceptionally strong or weak. Overpowering information can dominate a decision regardless of its position in the sequence, whereas weak information may be disregarded even if presented early. As part of a broader “Context Management Toolbox,” LSU-E must be deployed proportionately and with an understanding of these boundary conditions. Recognizing these factors is critical for forensic science to successfully navigate contextual contamination through appropriate and effective countermeasures.
110 years of rice breeding at LSU: realized genetic gains and future optimization
KEY MESSAGE: Strategic resource allocation in breeding programs is key to balancing cost-effectiveness and genetic improvement. This research aimed to understand the critical role of adopting advanced breeding tools and optimizing breeding strategies to ensure the sustainability and success of public breeding programs in meeting future food security challenges. In this context, there are two main objectives: estimate the genetic gains achieved over 110 years in the rice breeding program of Louisiana State University (LSU); evaluate through stochastic simulations the impacts of modern selection tools such as genomic selection (GS) and high-throughput phenotyping (HTP) on future genetic gains. Considering the 110 years, the average increase was 4.55 kg/ha per generation (23 breeding cycles). However, from 1994 to 2018, we observed more substantial trends in genetic gains, particularly for grain yield, which increased by approximately 56.54 kg/ha per year. Based on simulations, integrating GS and HTP demonstrated significant advantages, including shorter breeding cycles, enhanced selection accuracy, and reduced costs. Also, simulation results showed that this approach yielded the highest response to selection (4.68% per year) due to the synergistic effects of combining advanced phenotyping techniques with GS. Finally, we assessed the effects of balancing the number of parents, crosses, and progeny sizes to maximize genetic gains and maintain genetic variability. Variance component analysis indicated that progeny size had the greatest impact on total variance (36%), followed by the number of crosses (23%) and the number of parents (3.4%). The findings highlight the need for strategic resource allocation in breeding programs to balance cost-effectiveness and genetic improvement.
A practical tool for information management in forensic decisions: Using Linear Sequential Unmasking-Expanded (LSU-E) in casework
Forensic analysts often receive information from a multitude of sources. Empirical work clearly demonstrates that biasing information can affect analysts' decisions, and that the order in which task-relevant information is received impacts human cognition and decision-making. Linear Sequential Unmasking (LSU; Dror et al., 2015) and LSU-Expanded (LSU-E; Dror & Kukucka, 2021) are examples of research-based procedural frameworks to guide laboratories' and analysts' consideration and evaluation of case information. These frameworks identify parameters—such as objectivity, relevance, and biasing power—to prioritize and optimally sequence information for forensic analyses. Moreover, the LSU-E framework can be practically incorporated into any forensic discipline to improve decision quality by increasing the repeatability, reproducibility, and transparency of forensic analysts’ decisions, as well as reduce bias. Future implementation of LSU and LSU-E in actual forensic casework can be facilitated by concrete guidance. We present here a practical worksheet designed to bridge the gap between research and practice by facilitating the implementation of LSU-E.

What is a "collection?"
A collection is an interview, and as such, it is assigned a specific collection number, such as 4700.1234. There can be several recordings (indicated by a unique Tape #) within one collection if the person was interviewed on more than one occasion by the same interviewer.

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.

Do I have to come to campus to view the materials that I need?
The short answer is yes. Most of our special collections are only available in their physical formats. However, we do have some digital collections online, which are made available through the Louisiana Digital Library. We do participate in interlibrary loan services for select materials (typically microfilm) and we offer a variety of duplication options.
