This study provides the first causal analysis of the impact of expanding Computer Science (CS) education in U.S. K-12 schools on students' choice of college major and early career outcomes. Utilizing rich longitudinal data from Maryland, we exploit variation from the staggered rollout of CS...

In an environment where privacy is an increasing concern to users that communicate through a public network, anonymity systems can play a fundamental role in helping safeguard users' identities. The peer-to-peer (P2P) architecture has emerged as a promising paradigm for designing large-scale...

Many applications require predicting not a just a single variable, but multiple variables that depend on each other. Recent attention has therefore focused on structured prediction methods, which combine the modeling flexibility of graphical models with the ability to employ complex, dependent...

Local area networks (LANs) provide links between computing devices, such as workstations, file servers, and printers, over a relatively small geographic area (usually within a single building or organization). While computer networks have existed for almost thirty years, networking technology...

Program dependences are syntactic relationships between program statements, which are used in several areas of computer science to obtain "approximate" information about semantic relationships between statements. There are two basic types of program dependences: control dependences, which are...

This study examines the design and development of computer-aided composition (CAC) software and its implications for Composition in general. The aims of the study were to identify the who and how of CAC software design and possibly construct models for CAC software development. In addition, the...

In recent years, fast spreading worms have become one of the major threats to the security of the Internet. Code Red, Nimda, Slammer, Blaster, MyDoom... these worms kept hitting the Internet and caused severe damage to our society. However, until now we have not fully understand the behaviors of...

Information dissemination is the very reason for the existence of the Internet. Within the community of independent entities that make up the Internet, the quality of openness that has contributed to scalability and connectivity has also introduced numerous security and privacy challenges. This...

Social and computer networks permeate our lives. Large networks, such as the Internet, the World Wide Web (WWW), AND wireless smartphones, have indisputable economic and social importance. These networks have non-trivial topological features, i.e., features that do not occur in simple networks...
