Phytoplankton Responses to Changing Irradiance and Carbon Fertilization
Phytoplankton play a crucial role in marine ecosystems due to their innate ability to fix carbon. As atmospheric CO2 levels continue to rise from fossil fuel combustion, the resulting increase in dissolved CO2 and the concurrent decrease in ocean pH are likely to impact the phytoplankton community. The response of phytoplankton to elevated CO2 can vary significantly among species and environmental conditions (e.g. light, temperature, nutrient availability). To address these variations, an experiment was conducted using a controlled photobioreactor system, maintaining high and low light, constant temperature, nutrient levels, and two pCO2 concentrations. This study focused on two regionally relevant phytoplankton in the northern Gulf of Mexico. Skeletonema (a diatom) increased growth rates with the combination of high light and high carbon, but this was not accompanied by increases in particulate organic carbon and nitrogen (POC/N). In contrast, Micromonas commoda (a green alga) did not show changes in growth rate or POC/PON but allocated more energy towards photosynthesis. Additionally, Skeletonema displayed a decoupling between growth rate and silicification, leading to higher biogenic silica content per cell in elevated pCO2 environments. These results highlight the necessity for genera-specific and regionally focused research, as the physiological plasticity among phytoplankton can vary
Relation of Linguistic Awareness Skills to Reading and Spelling for Autistic and Non-Autistic Elementary School–Age Children
For non-autistic children, it is well established that linguistic awareness skills support their success with reading and spelling. Few investigations have examined whether these same linguistic awareness skills play a role in literacy development for autistic elementary school–age children. This study serves as a first step in quantifying the phonological, prosodic, orthographic, and morphological awareness skills of autistic children; how these skills compare to those of non-autistic children; and their relation to literacy performance.We measured and compared the phonological, prosodic, orthographic, and morphological awareness skills of 18 autistic (with average nonverbal IQs) and 18 non-autistic elementary school–age children, matched in age, nonverbal IQ, and real-word reading. The relations between linguistic awareness and the children\u27s word-level literacy and reading comprehension skills were examined, and we explored whether the magnitude of these relations was different for the two groups. Regression analyses indicated the relative contribution of linguistic awareness variables to performance on the literacy measures for the autistic children. The non-autistic children outperformed the autistic children on most linguistic awareness measures. There were moderate-to-strong relations between performances on the linguistic awareness and literacy measures for the non-autistic children, and most associations were not reliably different from those for the autistic children. Regression analyses indicate that the performance on specific linguistic awareness variables explains unique variance in autistic children\u27s literacy performance.Although less developed than those of their non-autistic peers, the linguistic awareness skills of autistic elementary school–age children are important for successful reading and spellin
Incorporating Generative AI to Promote InquiryBased Learning: Comparing Elicit AI Research Assistant to PubMed and CINAHL Complete
Generative artificial intelligence (GenAI) is transforming education, and faculty can either incorporate GenAI in intentional course design to promote inquiry-based learning (IBL) or resist its use. This study identified an effective strategy to intentionally integrate GenAI in the course design to promote IBL. A descriptive study design was used for graduate nursing students to compare the effectiveness of a GenAI literature search tool, Elicit: The AI Research Assistant, to PubMed and CINAHL. A two-phase framework was utilized to organize complex information and justify a preference. A rubric was designed to promote and assess critical thinking through IBL in educating graduate nursing students on information literacy and structuring a literature search. Discovering a relationship between the search tools, students identified the strengths (pros) and weaknesses (cons) of each tool and determined which tool was more effective in terms of accuracy, relevance and efficienc

Development of an Algorithm to Identify and Calculate the Amount of File Slack on an Image of a Given Drive
As society increasingly relies on technology, the rates of cyber crime have been increasing at exponential rates. Cyber criminals are also discovering new ways to hide evidence of their crimes. This study develops a forensic analysis algorithm to evaluate the amount of file slack on an image of a drive. Slack space, leftover drive space on a disk sector after a file has been written, can be exploited to hide data. The algorithm aims to detect and calculate this slack space to help direct forensic investigations. The algorithm was evaluated on a population dataset of 100,000 files with random data and random sizes from 1 to 4096 bytes. The initial ten experiments returned a 100% success rate, identifying all filenames and slack space accurately. To ensure reliability of the algorithm and to test against false-positives, two additional experiments were conducted with intentionally altered control data. In these experiments, the algorithm was able to accurately detect discrepancies. Future work can be done to enhance the algorithm for specific use cases, like reproducing data in slack space or navigating fragmented files. The algorithm’s success rates indicate that it can be useful in forensic investigations
Vase Made in Occupied Japan
This vase was made in Occupied Japan. It was found at the Maryland Street Site near downtown Mobile during excavations for the I-10 Mobile River Bridge Archaeological Project. This video was produced by the USA Center for Archaeological Studies and Motivation Media Inc. This project was funded by the Alabama Department of Transportation and the Federal Highway Administration. Project partners include the USA Center for Archaeological Studies, Wiregrass Archaeological Consulting, The Doy Leale McCall Rare Book and Manuscript Library, and the USA African American Studies Department.https://jagworks.southalabama.edu/cas-videos_artifact-highlights/1017/thumbnail.jp
