This book presents the reader with an understanding of the role played by matrix metalloproteinases (MMPs) in the normal and diseased central nervous system (CNS). These enzymes may be important to brain development, and may also contribute to tissue destruction, which is observed with inflammatory and degenerative conditions of the brain. The book provides a background on the biology of MMPs, and on the stimuli and conditions that are linked to an increase in their production and activity. It describes the targets of MMPs, which include matrix proteins such as collagen, soluble cytokines and chemokines, and cell surface receptors. Studies implicating MMPs in neuronal process outgrowth and cell migration in CNS development are covered. The book also touches on studies suggesting that, in certain situations, dysregulated MMP activity and/or production may be critical to blood-brain barrier breakdown and neuronal damage./a

This thesis presents the discovery of a surprising phase transition between a topological and a broken symmetry phase. Phase transitions between broken symmetry phases involve a change in symmetry and those between topological phases require a change in topological order; in rare cases, however, transitions may occur between these two broad classes of phases in which the vanishing of the topological order is accompanied by the emergence of a broken symmetry. This thesis describes observations of such a special phase transition in the two-dimensional electron gas confined in the GaAs/AlGaAs structures. When tuned by hydrostatic pressure, the ν = 5/2 and ν = 7/2 fractional quantum Hall states, believed to be prototypical non-Abelian topological phases of the Pfaffian universality class, give way to an electronic nematic phase. Remarkably, the fractional quantum Hall states involved are due to pairing of emergent particles called composite fermions. The findings reported here, therefore, provide an interesting example of competition of pairing and nematicity. This thesis provides an introduction to quantum Hall physics of the two-dimensional electron gas, contains details of the high pressure experiments, and offers a discussion of the ramifications and of the origins of the newly reported phase transition.

I'm Jeremiah Jones." He extended his hand to her. "I know," Dawn said. She had known that she would be around famous racecar drivers, but this was her first encounter. She was a little awestruck. "I'm Dawn Montgomery, Bryan Richardson's new personal assistant." "Nice to meet you," he said with a smile. Dawn was embarrassed. She was still in awe from meeting her first celebrity, and now she realized that she was standing there holding his hand and staring at him. She dropped his hand. She could feel her face getting warmer and warmer, but she refused to look away from him. Two weeks before her wedding day, Dawn's fiance cheated on her. Heartbroken, Dawn moves across the country looking for a fresh start. What she finds is a job as the personal assistant for racecar driver Bryan Richardson...and perhaps another chance at love. Jeremiah's a successful racecar driver, known to fans by his blue and black #91 Dodge. The tragedy in his life has left him isolated, both from God and from lasting relationships. When Dawn is almost run over by a tool cart, Jeremiah comes to the rescue, and they are both swept off their feet. As their love grows, Dawn must make the hardest decision of her life-her faith or her infatuation. Find out if Dawn puts on the brakes or gives in to the impulses of their Revved Up Hearts
Introduction to Positive Media Psychology summarizes and synthesizes the key concepts, theories, and empirical findings on the positive emotional, cognitive, and behavioral effects of media use. In doing so, the book offers the first systematic overview of the emerging field of positive media psychology. The authors draw on a growing body of scholarship that explores the positive sides of media use, including fostering one’s own well-being; creating greater connectedness with others; cultivating compassion for those who may be oppressed or stigmatized; and motivating altruism and other prosocial actions. The authors explore these issues across the entire media landscape, examining the ways that varying content (e.g., entertainment, news) delivered through traditional (e.g., film, television) and more recent media technologies (e.g., social media, digital games, virtual reality) can enhance well-being and promote other positive outcomes in viewers and users. This book serves as a benchmark of theory and research for current and future generations of advanced undergraduate students, graduate students, and scholars in communication, psychology, education, and social work.
