Development And Validation Of Simulation Protocols For Assessing Stresses In A Network Tied Arch With A Posttensioned Tie Girder, Kanchani Lakamalika Kumari Basnayake Mudiyanselage

Dissertations

Posttensioned concrete members; especially the posttensioned tie girders, are critical load resisting elements in network tied arch bridges. The stresses in the structure are influenced by the prestress losses that depend on the posttension force magnitude, time-dependent concrete modulus of elasticity, and concrete creep and shrinkage. The use of performance-based, high-strength, ternary mixes to promote the carbon neutral concrete and the need for executing multiple construction stages challenge the assessment of the state of stress in a completed bridge. The primary objective of this study is the development and validation of simulation protocols for assessing stresses in a network tied …

What drives oystershell scale invasions?

Connor Crouch

Kristen Waring

If you work with aspen in the American West, you may have heard of the invasive insect oystershell scale (OSS; Lepidosaphes ulmi). OSS was first observed causing aspen mortality in Arizona in 2016, and occurrences have since been observed in Utah, Nevada, and Idaho. One of the first questions we hear from practitioners about OSS-infested aspen is, “what’s causing these outbreaks?” This is an interesting question because OSS has been in North America for centuries and was documented on aspen in Arizona as early as the 1990s, but elevated incidents …

The Role Internal Stakeholders Play In Innovation In Large Corporations, Heloisa Benevides Pontes Aragao

Management Dissertations - Archive

Despite the vast existing literature on innovation, the investigation of work conditions that support the generation of ideas to feed the innovative process remains elusive. Holding the assumption that the entire organization is responsible for innovation, not only a specific department or set of experts, I aim to investigate the role two internal stakeholders play in innovation – employees and CEO. I empirically examine the relationship between voice climate – or the workforce perception about its participation in current discussions with ideas, suggestions, and thoughts - and explorative and exploitative innovation. Further, I consider the impact of CEO attributes (origin …
