• #### THE SUPPLY CHAIN MANAGEMENT BID PROCESS: AN EXAMINATION OF PROPOSAL RESPONSE AND BIDDING DECISIONS

This research is intended to examine transportation suppliers coming up short due to participation in and response to bidding procedures. A mixed-methods approach is utilized to investigate the bid process and related outcomes for the transportation supplier. This study explores the bid process from the perspective of the transportation supplier. The first study is based on a quantitative approach, utilizing the Analytical Hierarchy Process methodology (AHP). The second study uses qualitative methodology, specifically utilizing semi-structured interview protocol. For the quantitative analysis, key factors related to the bidding process were studied, as the basis of the review. These factors were found through a systematic review of the literature, and are internal and external in nature. The results are that, of the factors studied, the Firm Related Internal Factor of Need for Work and Tender Related External Factor of Type of Bid are of the greatest significance when determining to bid. Key themes emerge from the semi-structured interviews, leading to the Assertation of Bid Submission Assessment, including a systematic review of relationships, current market conditions, and risk appraisal for the transportation supplier. This research explores economic, relational and strategic impacts on supplier performance aligned with the bid process, and how supply chain companies can build effective bid responses to enable practitioners to improve stability and financial performance, while avoiding supply chain disruptions. To better understand proposal response will aid the transportation supplier with restoring profitability levels lost, due to the bidding process (buyer to transportation supplier).
• #### Strategies in Acting for Operatic Performance: Empowering the Powerful

This thesis intends to explore the strategies, consequences and goals of acting in one of the most celebrated western artforms: opera. Told primarily through a first person narrative, and project based, the research of this piece culminated in three semesters teaching Oprea Workshop through Boyer School of Music at Temple University. Research methods included: Directing work before graduate school; Interviews and surveys with collaborators;Personal observation; and Scholastic work surrounding historic acting teachers. The main finding: My goals as a director and educator mimic many of the acting teachers before me: to connect gestures to the internal life of the performer and to strive towards a more perfect amalgamation of music text and stagecraft in presenting both new work and inherited repertoire for opera. I found disparities not in the goals, but in the “how”. My findings through my work are that the “how” is in bravery, kindness, and empowerment of the singer. Through scaffolded and varied techniques, each performer can cultivate their own collaborative strategies when developing characters and integrating movement into their vocal performances and storytelling. An empowered singer is an effective singer that can live and advocate for better art holistically in this world.
• #### The Origin, Present, and Future of Regional Art Museums — Using the Woodmere Art Museum as a Case Study

This paper uses the Woodmere Art Museum in Philadelphia as a case study to examine the origins and institutional evolution of American regional art museums, identify some of the challenges they currently face, and the important civic and cultural roles they play in their communities. The chapter “Origins” provides a basic overview of Woodmere’s founding and history and considers how, within an American context, such museums eventually evolved from private galleries to publicly engaged nonprofit organizations over the course of the twentieth century as their missions, stakeholders, and audiences evolved. Like other regional art museums that demonstrate the same model, Woodmere’s regional identity and its focus on local art deepen the ties between itself and the community it serves and creates cultural resonances that make regional art museums an irreplaceable part of the American museum industry. However, small regional art museums face important challenges as their finances are more vulnerable, and they must deal with some of the same social, institutional, and ethical issues faced by larger public-facing institutions with a smaller pool of resources. The chapter “Present Challenges” looks at the need to develop sustainable management and financial structures and inclusive strategies to understand and build on audience relationships as a way to survive and grow. The final chapter of the paper “Imagined Futures” concludes and specifically addresses the challenges and possibilities presented by the pandemic, various social justice movements, and the call for institutions to reckon with their own histories in order to form a clear path for the future of regional art museums.
• #### MOBILE POLLING AND SELF-REGULATION: HOW STUDENTS MAY BE TEMPTED WITH DISTRACTIONS

Mobile polling is a widely used classroom response system at the university level. The current study examines the predictors and outcomes of mobile polling including self-regulation and academic achievement. Furthermore, this study explores whether or not mobile polling benefits some students more than others, specifically those with higher levels of self-regulation. The data was collected from two separate University classrooms taught by the same teacher (n = 66). The first section of students were to use mobile polling software after taking their midterm exam and use the software for the remainder of the semester. The other section of students served as the control group and received the same instruction, Powerpoints, and assignments minus the usage of mobile polling. All students from both classes were given an 89 question survey known as the Barkley Deficits in Executive Function Scale (BDEFS) which measured their ability to self-regulate their behavior. A hierarchical regression model was used to find that mobile polling had no statistical significance on academic achievement at the end of the semester. The only significant predictor throughout the entire study was the initial achievement variable, which was the scores from the midterm exam. Another hierarchical regression model found that self-regulation, measured with the use of the BDEFS system, was not a significant predictor of academic achievement. When initial achievement was controlled for, the Overall EF score from the BDEFS system revealed that self-regulation had zero effect on the variance as denoted by R Square and the R Square change in the regression model. Supplemental analysis revealed that Overall EF is a significant predictor of academic achievement when a Repeated Measures ANOVA was used, though the R Square change was still low. Factor analysis was used to find which questions loaded together under five subscales, truncating the BDEFS system and revealing that Self-Restraint/Inhibition traits were a better predictor than the overall score from the BDEFS questionnaire yet was not a significant predictor of achievement. Finally, a 2 x 2 ANCOVA that investigated the interaction between high/low levels of Self-Regulation and usage of Mobile Polling and found that it did not significantly affect academic achievement. In fact, the highest mean came from the completely opposite group as expected, which was students in the control group with lower levels of self-regulation.

• #### ANION EFFECTS IN HOMOGENOUS PALLADIUM CATALYSIS AND LUMINESCENT PROPERTIES OF COPPER(I) COMPLEXES BEARING A WEAKLY-COORDINATING ANIONIC N-HETEROCYCLIC CARBENE LIGAND

The general theme of this dissertation concerns how the locality of an anionic moiety, be it a weakly coordinating anion or an anionic ligand, affect the spectroscopic and structural properties of organotransition metal complexes. Probing the columbic interactions between traditional and novel weakly coordinating anions with transition metal complexes, enables synthetic chemists to select anions that can improve catalytic transformations, impart stability of reactive intermediates, or develop new mechanistic insights. Additionally, presented herein is the manifestation of a new class of luminescent copper complexes which bear a weakly coordinating anionic N-heterocyclic carbene ligand.Firstly, a qualitative scale of coordinating ability is prepared by pairing traditional anions and weakly-coordinating anions with [Pd(IPr)(C(O)C9H6N)]+. NMR, IR, Computation, %Vbur, and X-ray crystallographic techniques are used to study the solution and solid-state interactions of these salts. During this study, a novel anion, denoted IMP- is prepared where two B(C6F5) groups are bridged by a phenyl imidazole core. Ultimately, it was found that sterics dictate coordinating ability observed by NMR and %Vbur, while IR and computation show the electronic effects of anion coordination. Continuing our understanding of the interplay between cation and anion, anionic Au(I) complexes are synthesized and paired with the same palladium cation in our first investigation. The framework of these Au(I) anions features a weakly coordinating N-heterocyclic carbene ligand that bears a borate moiety of the NHC backbone. Facile dissociation of a dimethyl sulfide ligand with metal alkoxide/phenoxides/thiophenoxides affords sodium or potassium salts. With these anions in hand, ion pairs are isolated in polar solvents and in the solid state. Au anions reside in the outer sphere of the palladium cation; like that of weakly coordinating anions such as BArF4-. Lastly, Luminescent group 11 organometallic complexes featuring N-heterocyclic carbene (NHC) ligands offer a swath of applications; catalytic transformations in organic chemistry to inorganic material uses in light emitting technologies. Conventional complexes are of the type NHC-M-X, where M is Cu, Ag, or Au and X represents anionic ligands that are often prone to hydrolysis. In this dissertation, Cu(I) complexes featuring this N- heterocyclic carbene ligand bearing a weakly coordinating anionic substituent (WCA-NHC) are prepared. (WCA-NHC)-M-L are air and moisture stable and differ from conventional NHC-M-X in that the metal can be supported by 2 datively-bound ligands. Initial computation reveals a change in dipole of (WCA-NHC)-Cu-PR3 charge transfer compared to that of reported NHC-M-X. By exchanging triphenylphosphine for diphenyl-2-pyridyl phosphine, we can change the emission wavelength by about 200 nm.
• #### GEOSPATIAL APPROACHES FOR UNDERSTANDING THE ROLE OF RESIDENTIAL MOBILITY AND AREA-LEVEL FACTORS IN COLON CANCER SURVIVAL DISPARITIES.

A primary reason geospatial approaches are important in cancer research is that health and disease are shaped not only by factors such as age, race/ethnicity, genes, and clinical care but also by the environment where individuals work and act. While the use of geospatial approaches in cancer research is growing, several limitations remain. For example, for most population-based studies, cancer patients' neighborhood environments are based on only a single location derived from the residence at the time of diagnosis.This dissertation aimed to address this limitation by using a unique dataset of colon cancer patients diagnosed in New Jersey that include residential histories obtained through a data linkage with LexisNexis, a commercial data collection company. By incorporating residential histories, I moved beyond a cross-sectional approach to examine how residential histories and socio-spatial mobility can change a patient’s geographic context over time and influence survival. To demonstrate the application of these data in this dissertation, I completed three case studies. In the first case study, I compared whether including residential histories changed the risk of death estimates by neighborhood poverty compared to the traditional approach when including only the location at the time of diagnosis. Results suggested that the risk of death estimates from neighborhood poverty were generally similar in strength and direction regardless of residential histories inclusion. This finding was likely a result of minimal socio-spatial mobility of colon cancer patients (i.e., patients generally moving to census tracts with similar poverty levels). The second study aimed to compare the geographic risk of death estimates when using single location and residential histories in spatial models. Results overall showed that the geographic patterns of the risk of death estimates were generally similar between the models. However, not accounting for residential mobility resulted in underestimated geographic risk of death in several areas. This finding was related to the fact that approximately 35% of the colon cancer patients changed the residency, and 12% of the initial study population left New Jersey after the diagnosis. In the third case study, I examined whether landscape characteristics (e.g., built environment) were associated with the risk of death from colon cancer independent of individual-level factors, residential mobility, and neighborhood poverty. The results indicated that an increasing proportion of high-intensity developed-lands substantially increased the risk of death, while an increase in the aggregation and connectivity of vegetation-dominated low-intensity developed-lands reduced the risk of death. These findings suggested that places lacking greenspaces could have worse access to recreational sites that promote physical activity. Overall, this dissertation expands our knowledge about the geographic disparities in colon cancer in New Jersey. It also provides specific examples of integrating residential histories and remote sensing-based products into cancer disparities research. Including residential histories opens up new avenues of inquiry to better understand the complex relationships between people and places, and the effect of residential mobility on cancer outcomes. Combining multiple socio-demographic and environmental domains to estimate the neighborhood effects on cancer outcomes will increase our potential to understand the underlying pathways.
