How can I search multiple databases at the same time?
Yes, there is a way to search multiple databases at one time. Generally, we recommend doing a search on the library's homepage (https://www.lib.lsu.edu/) using the Discovery search box when just starting out with your research or class assignment. It functions like a Google search in that it searches across many of our databases and the library catalog. Finally, if you prefer to meet with a research librarian who can give you a much deeper dive into searching and using our resources, you can set up an appointment with one. Here (https://www.lib.lsu.edu/staff?field_staff_type=2&search_api_staff=&fiel…) is a list of our research librarians organized by their subject areas. We especially recommend that faculty and graduate students contact their subject specialists when working on major research projects. Answered by: Electronic Resources
Where is the Center located?
The T. Harry Williams Center for Oral History is on the 2nd floor of the Hill Memorial Library. From the stairs: Go up the left staircase, take a left through the double doors, and walk straight through Quiet Study Space Room 201. The Center offices are located in the back right corner of this large room. From the elevators: Take the elevator up to 2, take a right through the double doors, and proceed to walk straight through the Quiet Study Space, Rm 201. The Center offices are in the back right corner of this large room. Answered by: Jennifer Cramer
How does the Center decide whom to interview?
The Williams Center chooses interviewees whose recollections best fit within one of our projects. If you know someone whose life experience fits within one of our projects, let us know about that person and why you think their stories would contribute to our oral history collection. To nominate someone for an interview, complete and return our bio data form. However, due to limited resources, a better alternative may be to interview the person yourself. We can provide guidance and training in oral history techniques so that you can interview people whose stories and memories deserve preservation. To learn more about our training, please visit Create an Oral History (https://lib.lsu.edu/oralhistory) Answered by: Jennifer Cramer
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.

Slavery in America and the World: History, Culture & Law
This HeinOnline collection brings together a multitude of essential legal materials on slavery in the United States and the English-speaking world. This includes every statute passed by every colony and state on slavery, every federal statute dealing with slavery, and all reported state and federal cases on slavery. Our cases go into the 20th century, because long after slavery was ended, there were still court cases based on issues emanating from slavery. To give one example, as late as 1901 Chief Justice Oliver Wendell Holmes, Jr. of the Massachusetts Supreme Judicial Court had to decide if a man, both of whose parents had been slaves, could be the legitimate heir of his father, because under southern law, slaves could never be legally married. The library has hundreds of pamphlets and books written about slaverydefending it, attacking it or simply analyzing it. We have gathered every English-language legal commentary on slavery published before 1920, which includes many essays and articles in obscure, hard-to-find journals in the United States and elsewhere. We have provided more than a thousand pamphlets and books on slavery from the 19th century. We provide word searchable access to all Congressional debates from the Continental Congress to 1880. We have also included many modern histories of slavery. Within this library is a section containing all modern law review articles on the subject. This library will continue to grow, not only from new scholarship but also from historical material that we continue to locate and add to the collection.

Enhancing imputation accuracy for catch-all missing data mechanisms with DFBETAS and leverage
This paper addresses the challenge of missing data in scientific research. It specifically examines the case of missing data arising from a “catch-all” missing not at ran (MNAR) mechanism, where missing values are disproportionately from one category, such as income or ethnicity in surveys. The study introduces the use of the regression diagnostic DFBETAS along with Leverage to improve the imputation of categorical data under such conditions. DFBETAS, a measure of influence in regression, is adapted to capture the intrinsic information of missing values, thereby enhancing the imputation process within a Bayesian multiple imputation (MI) framework. We validate the proposed approach through Monte Carlo simulations with data generating mechanisms based on probability distributions. The results show that incorporating DFBETAS and Leverage significantly improves the accuracy of imputations, optimizes the balance between its sensitivity and specificity reduces bias, and enhances confidence interval coverage of imputed estimates, especially as the strength of the catch-all mechanism increases. The study demonstrates that MI with DFBETAS and Leverage outperforms standard MI methods, offering a robust solution for handling categorical data with catch-all MNAR mechanisms. This advancement in imputation methodology provides a more accurate and efficient means of dealing with missing data in various research fields.
Exploring the Relationship between Wall Drop Punt Kick and Catch (Tripela Sports) Performance and Manipulative Tests of the Motor Competence Assessment Battery in Early Adolescents
Our aim in this study was to analyze associations between the two manipulative tests of the Motor Competence Assessment (MCA) battery and the Wall Drop Punt Kick & Catch (WDPK&C) motor task. One hundred and twelve early adolescents (60 boys; 52 girls; M age = 12.67, SD = 1.78 years) participated. Overall, strong correlations were found between the WDPK&C and the MCA manipulative tests, either separately (r = 0.802 for kicking, r = 0.762 for throwing) or collectively (r = 0.835). In boys, correlations between WDPK&C and MCA kicking (r = 0.722) and MCA throwing (r = 0.754) were similar. In girls, MCA kicking was more closely related to WDPK&C performance (r = 0.612) than MCA throwing (r = 0.330). These results reinforce the possible use of WDPK&C as a gross manipulative coordination test, either by itself or when integrated into motor competence batteries.

Association of weekend catch-up sleep with depression: A systematic review and meta-analysis
Background Weekend catch-up sleep (WCS) may alleviate weekday sleep deprivation, but its relationship with depression risk remains unclear. This systematic review and meta-analysis aims to explore the association between WCS and depression risk.Methods A comprehensive search was conducted in PubMed, Cochrane Library, Embase, Web of Science, and Scopus for observational studies published up to June 1, 2024. Data extraction and bias assessment were independently performed by two reviewers. Odds ratios (ORs) and 95 % confidence intervals (CIs) were calculated, with model selection based on the I2 statistic. Sensitivity analyses and publication bias tests were also conducted.Results A total of ten cross-sectional studies (326,871 participants) were included. Meta-analysis showed that WCS was significantly associated with a reduced risk of depression (OR = 0.80, 95 % CI: 0.68–0.90). Subgroup analyses showed moderate amounts of WCS (0–2 h) may be protective, but WCS beyond 2 h had limited protective effects against depression. Qualitative analyses showed that the protective effect of WCS against depression was more pronounced in men and middle-aged adults, and was particularly applicable to those who were sleep-deprived on weekdays.Limitations The cross-sectional design of included studies limits causality inference, and the sample primarily represents populations from the United States and South Korea, potentially affecting generalizability.Conclusions Moderate WCS is associated with lower depression risk in those with weekday sleep deficits, while excessive WCS may have diminishing or adverse effects. Further research should examine optimal WCS duration and underlying mechanisms.
Prediction of fish (Coilia nasus) catch using spatiotemporal environmental variables and random forest model in a highly turbid macrotidal estuary
Fish populations in estuaries are declining due to the changes in environmental conditions and fishing pressures. The estuarine fish behaviour is highly variable, influenced by both upstream fluvial and downstream tidal conditions. This study aims to predict the catch per unit effort (CPUE) of the Japanese Grenadier Anchovy (Coilia nasus) in the Chikugo River estuary by analyzing an extensive dataset of hourly fish catches and environmental variables through Random Forest (RF) models. The fish catch data for C. nasus, collected at 14.6–16 km upstream from the river mouth during the spawning season of every year from 2009 to 2020 using traditional fishing methods, was used. Along with these catch records, hydro-environmental variables such as salinity, turbidity, and temperature were monitored during the same period. The longitudinal variation of these environmental variables along the estuary (0–16 km) was measured during a fortnightly tidal cycle in September 2010. A total of 32 models (M1-M32) were developed to identify the optimal set of environmental variables influencing CPUE. The analysis highlights the significant impact of variables such as salinity, suspended sediment concentration (SSC), temperature, river discharge, and mean tidal range on CPUE. The results revealed that model M19, which incorporated salinity, SSC, and discharge, achieved the highest predictive accuracy (R2 = 0.89) and closely matched actual field conditions. Further, the results agree with previous research, as spatial distribution plots showed a preference for mature C. nasus habitats 15–16 km upstream from the river mouth. Additionally, the study found that temperature had a negligible effect on short-term CPUE predictions, likely due to its pronounced seasonal variability, suggesting that temperature may not be a critical factor for short-term CPUE predictions. This study highlights the significance of utilizing environmental variables to predict CPUE, emphasizing their role in understanding fish catch dynamics across spatiotemporal variations. The findings provide valuable insights for fisheries management, particularly in optimizing fishing zones based on environmental conditions to improve catch efficiency.
