OBJECTIVES To understand when patients use secure e-mail messaging with healthcare providers across several types of questions or concerns, associations between out-of-pocket costs for in-person visits and use of secure messaging, and to examine patient-reported impacts on care-seeking behavior and overall health. STUDY DESIGN Cross-sectional survey of patients in an integrated healthcare del...

Online criminals have adapted traditional snail mail and door-to-door fraudulent schemes into electronic form. Increasingly, such schemes target an individual's personal email, where they mingle among, and are masked by, honest communications. The targeting and conniving nature of these schemes are an infringement upon an individual's personal privacy, as well as a threat to personal safety. We...

In this paper we study supervised and semi-supervised classification of e-mails. We consider two tasks: filing e-mails into folders and spam e-mail filtering. Firstly, in a supervised learning setting, we investigate the use of random forest for automatic e-mail filing into folders and spam e-mail filtering. We show that random forest is a good choice for these tasks as it runs fast on large an...

The signature block is a common structured component found in e-mail messages. Accurate identification and analysis of signature blocks are important in many multimedia messaging and information retrieval applications such as email text-to-speech rendering. It is also a very challenging task, because signature blocks often appear in complex twodimensional layouts which are guided only by loose ...

We describe TripletMail, a system for outsourcing e-mail backups. The typical corporate mail server that handles receiving, sending and storing e-mails is replaced by two components: A mail server for SMTP/IMAP and a storage system which maintains several encrypted copies of each e-mail in racks of inexpensive servers. In this thesis, we focus on two problems of the storage system: In inexpensi...

This paper describes a portable electronic mail bouncer which sends detailed information back to the sender when a mail message can not be delivered to it’s intended recipient. The bouncer was originally written to handle a large merger between multiple DNS domains, and is implemented entirely in Perl5 as a mail delivery agent. The bouncer operates under the concept of "least privilege" so it’s...

Protocols to facilitate secure electronic delivery are necessary if the Internet is to achieve its true potential as a business communications tool. We present a protocol for secure e-mail that protects both the sender and the receiver, and can be implemented using current e-mail products and existing Internet infrastructure.

Artful processes are informal processes typically carried out by those people whose work is mental rather than physical (managers, professors, researchers, engineers, etc.), the so called “knowledge workers”. In this paper we propose the MailOfMine approach, to automatically build, on top of a collection of email messages, a set of workflow models that represent the artful processes laying behi...

Abstract A susceptible–infected–susceptible (SIS) model of multiple contagions on multilayer networks is developed to incorporate different spreading channels and disease mutations. Upper lower bounds basic reproductive numbers are derived rapid mutation processes analytically analyzed. In the special case where only two considered, analytical results obtained for network model, a competition w...

A study into the effects of bullying at work, including bullying via e-mail, was conducted in a large Multi National Corporation. A considerable amount of bullying was found on the e-mail system, with negative outcomes similar to those of conventional bullying. Bullying was associated with anxiety and tendency to quit, and negatively associated with job satisfaction and performance. The results...
