OBJECTIVE To evaluate the role of self-efficacy, anticipated negative consequences, and relationship quality in patient-initiated sex partner notification following treatment for sexually transmitted infections. SUBJECTS Two hundred forty-one 13- to 20-year-old subjects (83% women; 83% African American) diagnosed with gonorrhea, chlamydia, trichomonas, or nongonococcal urethritis. Subjects we...

OBJECTIVE This study illuminates the degree of psychological stress response experienced by spouses of cancer patients when given bad news at three different times (notification of the name of the disease, notification of recurrence, and notification of terminality) as well as the factors that influence the response and the health status of the spouse as measured by health-related quality of li...

Service-based computing is rapidly replacing the more-traditional approaches to architecting distributed systems. The critical advantage of service-based architectures is that they require only a specification of protocol, and not of API. As such, they engender a significantly looser coupling than prior techniques, thus facilitating seamless collaboration across systems and across administrativ...

Time needed to report surveillance data within the public health service delays public health actions. The amendment to the infection protection act (IfSG) from 29 March 2013 requires local and state public health agencies to report surveillance data within one working day instead of one week. We analysed factors associated with reporting time and evaluated the IfSG amendment. Local reporting t...

There is a growing need for distributed teams to analyze complex and dynamic data streams and make critical decisions under time pressure. Although intelligent software capable of making decisions is becoming more and more prevalent, some highly ambiguous situations still demand the guidance of human experts. Via a case study, we discuss potential guidelines for the design of software tools to ...

This working paper describes a new software application for smartphones, designed to gather timeuse data about the working day. Called random time sampling (RTS), the software was developed to overcome a void in the standard time-use survey data: namely, the lack of detail about activities undertaken and their social context during paid employment. The RTS system addresses the twin problems of ...

OBJECTIVE To assess the impact of body mass index (BMI) screening with parental notification on weight status for California public school students. DESIGN A natural experiment wherein nearly all California school districts conducted annual BMI screening in the fifth, seventh, and ninth grades, but parental notification of BMI screening results was optional. SETTING Data from mandatory fitn...

Dependencies among software projects and libraries are an indicator of the often implicit collaboration among many developers in software ecosystems. Negotiating change can be tricky: changes to one module may cause ripple effects to many other modules that depend on it, yet insisting on only backwardcompatible changes may incur significant opportunity cost and stifle change. We argue that awar...

To minimize unwanted interruption and information overload during surveillance, mobile police officers need to be supported by a mobile, contextaware notification system. This system adapts message presentation to message priority and context of use. A prototype is designed and evaluated in a simulated surveillance task, requiring users to attend to videos while handling messages on a mobile de...

Internet-scale Web services-based event notification services face several new challenges that have not been addressed in traditional event notification systems. In this paper, an Open Publish/Subscribe (OPS) model is proposed to address these new challenges. The openness of OPS model enables collaboration among different event notification systems from different organizations. The layered arch...
