To enable computer designers to better evaluate the architectural needs of operating systems, we have developed Monster , a tool which combines hardware and software monitoring techniques to unobtrusively obtain system performance data. This report is split into two major parts. In Part I, we argue the need for OS performance evaluation tools, summarize previous hardware and software based moni...

BACKGROUND Information about the variation in the risk for venous thromboembolism (VTE) and in prophylaxis practices around the world is scarce. The ENDORSE (Epidemiologic International Day for the Evaluation of Patients at Risk for Venous Thromboembolism in the Acute Hospital Care Setting) study is a multinational cross-sectional survey designed to assess the prevalence of VTE risk in the acut...

CAPPA included caregiver assessments of global medication satisfaction, global symptom control, and satisfaction with ADHD medication attrib...

Frailty is an age-related syndrome that has been well-described in the last ten years. It can be characterized by diminished strength, endurance, and reduced physiologic function. With multiple causes and contributors, frailty is highly correlated with functional decline and chronic diseases. Currently, there are no standardized tests or biomarkers that can be used to identify frail patients, t...

The global mean OH concentration ([OH]GM ) has been used as an indicator of the atmospheric oxidizing efficiency and its changes over time. It is also used for evaluating the performance of atmospheric chemistry models by comparing with other models or with observationally-based reference [OH]GM levels. We contend that the treatment of this quantity in the recent literature renders it problemat...

BACKGROUND The correct knowledge of standard case definition is necessary for frontline health workers to diagnose suspected diseases across Africa. However, surveillance evaluations commonly assume this prerequisite. This study assessed the knowledge of case definitions for health workers and their supervisors for disease surveillance activities in rural Kenya. METHODS A cross-sectional surv...

The digital divide is widely recognized as a contemporary problem between society and techno logy. Strategies for bridging the digital divide are often informed and guided by quantitative assessments of the deployment of information communication technologies. There are few rigorous qualitative attempts to assess the digital divide from either an ethnographic or a futures-oriented perspective. ...
