The Influence Of Social Identity On Psychological Safety, Organizational Performance, And Employee Learning, Antonio Meeks

Masters Theses and Doctoral Dissertations

Organizations struggle to recruit and retain top talent. The challenge to keep employee talent was exacerbated by COVID-19. However, there has been a downward trend of employees in the workplace and a continued struggle to fill key roles with eligible workers since 1999. Filling key roles is only one issue impacting organizational success. Another concern is keeping employees engaged to do the work. Research suggests that over 65% of employees are disengaged or actively disengaged at work (Burke, 2019; Iqbal, Shabbir, Zameer, Khan, & Sandhu, 2017; Motyka, 2018). Disengaged and actively disengaged workers do not help the organization meet its …

Understanding The Positive And Negative Aspects Of Different Calling Intensities, Sally Hoffman

Masters Theses and Doctoral Dissertations

This study examined the relationships among occupational calling intensity (OCI), personal calling intensity (PCI), occupational engagement (OE), personal engagement (PE), and need for resource recovery (NFRR). OCI, an all-consuming desire to have a significant positive impact through employment, is often associated with high OE but may also be linked to high NFRR, suggesting that OE mediates the relationship between OCI and NFRR. This study also explored whether PCI, which refers to a calling outside of employment, exhibits the same relationships with PE and NFRR as OCI. Data from 193 participants were analyzed using correlational and regression techniques. The findings revealed …

The State Of Herbaria In Tennessee, Meredith Woodward

Masters Theses and Doctoral Dissertations

The herbaria of Tennessee were the focus of substantial efforts to digitize southeastern plant specimens in the United States between 2014-2019. Because of that work, 13 of the 14 herbaria were digitized to varying degrees, producing approximately 894,000 digital vascular plant records. For the first time, the content of these collections could be elucidated and analyzed for bias. Defining their content demonstrates their disposition as a resource for Southeastern botany, and understanding biases can aid in intentionally allocating resources for future work regarding deeper digitization or on-the-ground documentation.
