the crossing number of a graph  is the minimum number of edge crossings over all possible drawings of  in a plane. the crossing number is an important measure of the non-planarity of a graph, with applications in discrete and computational geometry and vlsi circuit design. in this paper we introduce vertex centered crossing number and study the same for maximal planar graph.

Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Printer-friendly Version Interactive Discussion EGU Abstract In this technical note we present the exact form of the Zeldovich factor for heterogeneous nucleation on spherical pre-existing particles. We study the error caused by planar pre-existing surface approximations, which have been used in our earlier heteroge...

Much of what we recognize as political is a function of choice. Political phenomena such as elections, wars, legislation, and protests occur because people choose to take particular actions at particular times. For scholars, the concept of choice is important because it primes us to consider not just the existence of an action, but also the volition that produced it. Such priming of volition is...

Back-channel feedback, responses such as uh-uh from a listener, is a pervasive feature of conversation. It has long been thought that the production of back-channel feedback depends to a large extent on the actions of the other conversation partner, not just on the volition of the one who produces them. In particular, prosodic cues from the speaker have long been thought to play a role, but hav...

Information technology (IT) adoption research recognizes theoretical limitations in discerning if and when user behavior results from perceived external infl uences or from personal volition. A clear understanding of this issue requires a precise distinction between mandatory and volitional behaviors. Consistent with organismic integration theory (OIT), this study situates the locus of user mot...

This book aims at improving our understanding of the processes supporting voluntary action by looking at conditions in which the will is impaired or even breaks down. We use this introductory chapter to prepare the ground for contributions by philosophers, psychologists, neuroscientists, and psychiatrists that tackle the experience of acting intentionally, the ability to make decisions and impl...

Background: The notion of “just culture” has become a way for hospital administrations to determine employee accountability for medical errors and adverse events. Method: In this paper, we question whether organizational justice can be achieved through algorithmic determination of the intention, volition and repetition of employee actions. Results and conclusion: The analysis in our paper sugge...
