Exploring Structure-Property Relationships Of Gags To Tailor Ecm-Mimicking Hydrogels, Ralf Zimmermann, Carsten Werner, James Sterling

Business and Information Technology Faculty Research & Creative Works

Glycosaminoglycans (GAGs) are a class of linear polysaccharides that are ubiquitous in the extracellular matrix (ECM) and on cell surfaces. Due to their key role in development, homeostasis, pathogenesis, and regeneration, GAGs are increasingly used in the design of ECM-mimicking hydrogels to stimulate tissue formation and regenerative processes via specifically orchestrated cell-instructive signals. These applications first and foremost build on the ability of GAGs to effectively bind, protect, and release morphogens. The specificity and strength of morphogen-GAG interactions are largely governed by the number and spatial distribution of negatively charged sulfate groups carried by GAGs. Herein, we summarize a mean-field …

Point/Counterpoint: Is There A Case For Subsidizing Sports Stadiums?, Victor Matheson

Economics Department Working Papers

In recent decades, governments have committed enormous public resources to subsidize construction of new stadiums, and the dollar value of taxpayer contributions for these subsidies continues to climb. Spending of taxpayer dollars includes both direct subsidies from state and local governments, as well as indirect subsidies from the use of tax-exempt bonds to finance construction. In granting stadium subsidies, governments claim that the stadiums are a public good that attracts tourists and businesses, thereby generating increased spending and job creation—benefits that flow to the community rather than to team owners. But do such benefits exist, and are they large enough …

Instead Of Predicting The Future, We Should Get On With Creating The Future, Shweta Midgil, Richard Smith

Research Collection Lee Kong Chian School Of Business

It is important to note that there is a lot of hype about “Digital Disruption” these days. We see too many organizations trying to take on the topic of “Digital” without really focusing their efforts on something that is meaningful to the people in the organization. Leaders going around talking about digital disruption or digital transformation does not serve any purpose – only creates anxiety and uncertainty. In other words, leaders would be better served to break down the topic into meaningful topics that are linked to areas of the business.
