    Content: A Granger Causality study is conducted to understand the causality loop between online reviews and consumer acquisition in YouTube. This paper aims to refute the long-lasting assumption that online reviews are exogenous to sales. By doing so, this paper posts a challenge in understanding the impact of online reviews on sales. By tracking 75 videos for 64 days, this paper found that negative online reviews drive and reflect on consumer acquisition, but positive online reviews only drive sales. These findings not only suggest caution to scholars that treat online reviews exogenous, but also provide specific implications to practitioners regarding positive and negative online review valence

    Content: This thesis first reveals the mechanism of Görtler instabilities and then demonstrates how transitions at hypersonic flows can be effectively controlled (either promoted or suppressed) with Görtler or Klebanoff modes. It focuses on understanding and controlling flow transitions from mild laminar to fully turbulent flows at high speeds—aspects that have become crucial at the dawn of an incredible era, in which hypersonic vehicles are becoming available. Once this occurs, it will be possible to travel from Beijing to Los Angeles within just 2 hours, and we will all live in a genuinely global village—and not just virtually, but physically. Görtler instabilities have often been used to promote flow transition in hypersonic vehicles. However, how Görtler instabilities are excited and how they evolve in hypersonic flows are questions that have yet to be answered.
