NEGATION IS SOMETHING THAT WE DO. It is typically a judgment that we make, a judgment that something is not the case, and it usually—albeit by no means exclusively—takes the form of a statement. We make negative existential judgments (“There is no longer a Cold War,” “Inflation doesn’t exist in this economy”) and negative predicate judgments (“Two is not greater than three,” “The suspect’s not ...

We define crying as a multimodal behavior consisting of tears, nonverbal vocalizations (wails, sobs), and facial expressions of distress. Being most frequent in infants, and arguably less subject to cultural display rules, we take infant crying as the prototypical form. Correspondingly, we take distress (sadness, fear, anger, or pain) as the core condition expressed through crying since, althou...

My research interests are broadly defined by the field of Human-Computer Interaction (HCI), with a specific interest in the areas of Computer Supported Cooperative Work (CSCW) and Interaction Design. A central goal of my research is to contribute not only through the creation of applications and tools, but to contribute to science by providing an understanding of human-behavior and factors that...

In the last few years, my research has been in geometric group theory, which attempts to understand groups via the spaces upon which they act. The last two decades have seen tremendous progress in our understanding of infinite discrete groups, and many longstanding open problems have been solved using geometric methods. I am particularly interested in coarse negative and non-positive curvature,...

“Experimetrics” refers to formal procedures used in designed investigations of economic hypotheses. Fundamental experimetric contributions by Ronald A. Fisher provided the foundation for a rich literature informing the design and analysis of economics experiments. Key components of this foundation include the concepts of randomization, independence and blocking. Experimetric analysis plays a ce...

In this present study analytical method based on Riccati Equation as for converting the Nonlinear Lakshmanan-Porsezian-Daniel (LPD) equation into the nonlinear ODE and finding soliton solutions of this sustem discused. Obtaining solutions are new and obtained from wave transformation. The obtained results show that the presented method is effective and appropriate for solving nonlinear differen...
