Academic Executives’ Perceptions of Team Relations and How These Relationships Impact Leadership and Institutions
Get PDFResearch suggests there are many factors that contribute to the success or failure of university leaders. This study explores one of these factors—the relationships between the university president and their executive team and the group’s collective sociability—and uses social capital theory to suggest executive teams utilize relationships to influence leadership and the institution. The researcher employs a qualitative phenomenological approach using purposeful sampling to reveal how presidents and their executive teams perceive how their relational experiences impact the team and university. The research found that three themes emerged that broadly cover how organizational structure promotes or hinders relationship building, how relations are maintained and how the environment provides obstacles and opportunities for these academic executives to navigate. This study contributes to the body of literature related to educational leadership by offering current university executives and individuals aspiring to be a university or college executive insight into how the relationships among the executive team can be helpful or a hindrance

Characterizing the function of lyases involved in the biosynthesis of Phycoerythrin I and II from marine Synechococcus cyanobacteria
No full textMarine Synechococcus are the second most abundant oxygenic phototrophs in the open ocean. They are efficient at harvesting available light using complex antenna, or phycobilisome, composed of allophycocyanin proteins and extended rod structures of phycocyanin and one or two types of phycoerythrin (PEI and PEII). This dissertation focuses on the enzymes called bilin lyases required for the biogenesis of PEI and PEII in marine strains of Synechococcus which undergo type 4 chromatic acclimation (CA4). I used interruption mutant analysis, high performance liquid chromatography, a protein expression system in E. coli, and liquid chromatography tandem mass spectrometry to characterize the role of these bilin lyases.
A candidate lyase, CpeY, in the strain Synechococcus sp. RS9916 was characterized. Using molecular techniques and a cpeY- interruption mutant, I show that CpeY adds phycoerythrobilin to C82 of CpeA in the presence or absence of the chaperone-like protein CpeZ in a recombinant protein expression system. These studies demonstrate that CpeY attaches phycoerythrobilin to as much as 72% of CpeA, making it one of the most efficient phycoerythrin lyases characterized to date.
CpeU is similar to the CpcS/U family of lyases hypothesized to be a putative lyase on a phycoerythrin subunit. Analysis of purified phycobilisomes by HPLC and mass spectrometry shows that the cpeU- mutant was defective in bilin addition to CpeA and MpeA in green light and to CpeA in blue light, suggesting it plays a role in bilin changes during CA4. In the recombinant expression system, CpeU interacts with PEB, potentially sequestering it away from CpeY, thus decreasing the PEB attachment capabilities of CpeY.
I compared the activity of two homologs of the candidate lyase-isomerase MpeV from two closely related strains of Synechococcus. I show that Synechococcus sp. RS9916 MpeV is the lyase-isomerase responsible for doubly-ligating phycourobilin at C50, 61 positions on the CpeB and MpeB proteins from RS9916. However, the strain Synechococcus sp. WH8020 MpeV demonstrated lyase-isomerase activity on RS9916 CpeB and both WH8020 and RS9916 MpeB, yet it ligated phycoerythrobilin to WH8020 CpeB, suggesting the substrate protein CpeB may have an influence on the isomerization activity in addition to the bilin lyase

The Jeep is Here to Stay! Projections of America and Franco-American Relations During World War II
Get PDFDuring World War II, the Office of War Information produced American and Allied propaganda that was used at home and abroad. Robert Riskin, head of the Bureau of Motion Pictures Overseas Branch, was responsible for creating Projections of America, a documentary film series made to introduce foreigners to America whilst combating negative impressions of Americans that arose in the interwar years. Films from Projections of America contained themes of American culture, ideology, industry and technology, and democracy. In France, these films were used to sway French opinion of Americans while promoting friendship and appreciation for American culture. Ultimately, the films served to prepare the French for the oncoming American occupation. This paper will argue that the Projections of America film series and its use in France successfully promoted American culture while also negating negative perceptions of Americans during World War II
Performance Funding and Stakeholder Perceptions: The Rise and Fall of the Louisiana GRAD Act
Get PDFPerformance based funding ideology creates a disconnect in communication ranging from state coordinating officials to academics responsible for the actual education to the students (Shin, 2010). The purpose of this dissertation was to analyze higher education stakeholders’ perceptions of performance funding by examining the development, design, implementation, and execution of the Louisiana Granting Resources and Autonomies for Diplomas Act (GRAD Act) and offer potential solutions based on the findings. A qualitative study using phenomenological methodology, and theoretical perspectives in the literature, was conducted amongst higher education participants involved with the GRAD Act at the state and campus levels in Louisiana. The findings from this study revealed shared experiences of higher education stakeholders in Louisiana concerning the development, design, implementation, and execution of the GRAD Act and strategies that can be useful in developing the next stages of a unified plan to meet and exceed higher education goals in Louisiana. The results of this study can be utilized as Louisiana leaders consider future funding policies for higher education. Overall, this study sought to add to the body of research on performance funding ideology by analyzing stakeholders’ perceptions of the GRAD Act and sharing implications for future development
Suitability of Fusing Vehicle Probe Data and Vessel Data to Contextualize the Multimodal Interaction Impacts on Corridor Mobility – a New Orleans Case Study
Get PDFUsing New Orleans as a case study, this thesis explores the conflation of vehicle probe data with various vessel datasets to characterize the interactions between container vessels and motor vehicles as it relates to interstate congestion in a port city. The case study investigates the impact of container vessel presence/size, fluctuations in container volumes, and container on barge services on roadway congestion. The exploration relies on comparing different conditions using cumulative distribution functions and the Innovative Trend Analysis. The results showed that fusing vehicle and vessel data is achievable and appropriate, but temporal and data completeness issues can effect results. The results also showed that by joining these modally disparate datasets together and analyzing them as one, additional context is added to discussions related to transportation operations and investment decision-making through either the confirmation or disproval of perceptions or expected results related to container truck traffic on an interstate
