New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a give thesis/dissertation in DRUM

    Effects of a Simulated Dicamba Misapplication on Non-tolerant Soybeans (Glycine max)
    (2015) Morris, Matthew; Ritter, Ronald L; Plant Science and Landscape Architecture (PSLA); Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Approval is pending for the registration of dicamba tolerant (DT) soybeans [Glycine max (L.) Merr.]. The use of dicamba on DT soybeans and other DT crops will increase. Risks associated with dicamba applications include off-target movement to sensitive crops. The objective of this study was to evaluate misapplication of dicamba on non-DT soybeans. Greenhouse and field studies examined a rate titration (0.004 to 0.5 lb ai a-1) of dicamba on non-DT soybeans (V3 stage - three trifoliates). Field studies also examined dicamba application to various growth stages (PRE- preemergence to R5- early pod fill) of non-DT soybeans. Results from the greenhouse and field studies showed that as the rate of dicamba increased, the level of injury to vegetative and yield components also increased. Soybean growth stage at time of application influenced the amount of injury. Less injury was observed when dicamba was applied at the PRE growth stage.

    The Influence of National Culture on Buyer-Supplier trust and Commitment
    (2005-12-02) Morris, Matthew; Corsi, Thomas M.; Logistics, Business and Public Policy; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Morgan and Hunt's (1994) Key Mediating Variable (KMV) Model has been demonstrated to be a useful means of exploring relationships between organizations. The model includes such key relational constructs as trust, commitment, cooperation, communication, shared values, and uncertainty, which have been studied extensively in the extant supply chain and marketing literatures. However, at present no comprehensive test of buyer-supplier relationships has used the KMV Model as the basis for analysis. In addition, no multi-industry study has applied the KMV Model to investigate its usefulness in other industries. Finally, the applications of the KMV Model thus far have not included testing for its usefulness across national boundaries. The present study addresses all three of the gaps above. Using responses from U.S.-based purchasing professionals, the current study replicates the KMV Model within a new population and addresses the three gaps: First, by investigating the buyer-supplier relationship; second, by sampling respondents from three industries (fabricated metal products; industrial machinery and equipment; and electronic and other electric equipment); and third, by collecting a sample with an internationally diverse supply base. The findings suggest that the KMV Model remains valid for predicting levels of trust and commitment in buyer-supplier relationships across the three industries. In addition, the analyses suggest that the KMV Model is a reliable predictor for trust and commitment, as well as for their respective sources and outcomes, in differing cultures at the national level.
