Get PDFThese items include materials from Informational Services at Marshall University from 1994-2011. Items were received in 2022 and include notable materials about various filmed events across campus during the period year. Items are on disc and are labeled numerically and by title of event. For the discs with just numbers but no titles, we have not examined these discs digitally to see what is on them. This is not an exhaustive list, but the attached inventory will give a broad overview of what is contained in each of the boxes...when possible
Longitudinal Associations of Conscientiousness and Neuroticism With Perceived Mastery and Constraints for Aging Adults
Get PDFIt has not been well understood how conscientiousness and neuroticism are associated with two related but distinct dimensions of perceived control (i.e., perceived mastery and constraints) among aging adults. The present study examined these associations and their change over time, while addressing whether they differ by age or gender. For respondents aged 50+ at baseline (N = 2,768) in the Midlife in the United States (MIDUS) study, multilevel modeling analyses were conducted to assess how conscientiousness and neuroticism predicted perceived mastery and constraints over 2 decades. As expected, higher conscientiousness and lower neuroticism (for both between- and within-person variability) predicted higher perceived mastery and lower perceived constraints overall. Nuanced findings emerged related to age, gender and change over time for different associations of conscientiousness and neuroticism with the outcomes. These findings can inform future research suggesting directions of further investigations for these complex associations
Longitudinal Associations Between Personal Growth and Cognitive Functioning in Adulthood
Get PDFObjectives: While personal growth has been found to be associated with multiple aspects of health in adulthood, its associations with cognitive functioning have not been fully understood. The present study aimed to assess both directions of such longitudinal associations.
Method: Using data from the second wave (Time 1 [T1]) and third wave (Time 2 [T2]) of the Midlife in the United States (MIDUS) study (N = 4,206; mean age = 56.0 [standard deviation (SD) = 12.3]), a longitudinal measurement model containing latent variables of episodic memory and executive function was first constructed. Built on the measurement model, a cross-lagged panel model was analyzed to assess relationships between personal growth and the two areas of cognitive functioning, in which T1 personal growth predicted residualized changes in episodic memory and executive function, and T1 episodic memory and executive function predicted change in personal growth, controlling for covariates.
Results: T1 personal growth significantly predicted smaller decreases in episodic memory, whereas it did not predict change in executive function. T1 episodic memory, but not T1 executive function, significantly predicted smaller decreases in personal growth.
Discussion: The present findings were unique, particularly implying potential longitudinal reciprocity between personal growth and episodic memory. These findings and implications can inform future research aimed at exploring approaches to promoting personal growth and cognitive functioning among aging adults
Leveraging Herbaria Specimens: A New 3D Imaging Protocol and Analyses of Diversity of West Virginia Rosids
Get PDFHerbaria are repositories of plant natural history, whose data can provide insights into the life histories of plant taxa over space and time. Recent initiatives to digitize herbarium data have made studies over broad geographic and taxonomic extents possible, with the ability of scientists to access data from large databases of herbaria. Most of the digitization initiatives have focused on flat 2D herbaria sheets, but herbaria also include 3D collections, such as fungi, mosses, lichens, and dry fruits. In Chapter 1 we propose an easy and cost-effective workflow that uses free photogrammetry software to produce 3D images of 3D herbaria specimens. We tested four free to use photogrammetry software and created 3D images of five types of 3D specimens: a fungus, a moss, a lichen, a pinecone, and a compound fruit. With our workflow using equipment already present in most herbarium digitization stations, we produced 3D specimens in less than an hour. The software 3DF Zephyr Free gave the best results across each specimen type. Our workflow has provided an easy and low-cost method of producing 3D images that can be used to digitize 3D specimens in a similar manner to 2D herbaria sheets. In Chapter 2 we used herbaria data to analyze the spatial patterns of diversity of a major clade of plants, the Rosids, that contain most hardwood trees in West Virginia, and are the dominant plant species in the state. We used phylogenetic diversity to assess the diversity of this clade across the Level IV Ecoregions of West Virginia. Phylogenetic diversity (PD) is a metric that incorporates the evolutionary history of an area of interest. Ecoregions are defined by the Environmental Protection Agency (EPA) as areas of similar habitat, climate, and species composition. Our results indicated high PD in the eastern portion of the state in the Monongahela National Forest and low PD in the southern portion of the state in the Dissected Appalachian Plateau ecoregion. Analyses such as ours are important for informing conservation priorities, as they identify specific areas that are more biodiverse
