Age Optimal Information Gathering and Dissemination on Graphs
We consider the problem of timely exchange of updates between a central
station and a set of ground terminals , via a mobile agent that traverses
across the ground terminals along a mobility graph . We design the
trajectory of the mobile agent to minimize peak and average age of information
(AoI), two newly proposed metrics for measuring timeliness of information. We
consider randomized trajectories, in which the mobile agent travels from
terminal to terminal with probability . For the information
gathering problem, we show that a randomized trajectory is peak age optimal and
factor- average age optimal, where is the mixing
time of the randomized trajectory on the mobility graph . We also show that
the average age minimization problem is NP-hard. For the information
dissemination problem, we prove that the same randomized trajectory is
factor- peak and average age optimal. Moreover, we propose an
age-based trajectory, which utilizes information about current age at
terminals, and show that it is factor- average age optimal in a symmetric
setting
Open-source digital technologies for low-cost monitoring of historical constructions
This paper shows new possibilities of using novel, open-source, low-cost platforms for the structural health monitoring of heritage structures. The objective of the study is to present an assessment of increasingly available open-source digital modeling and fabrication technologies in order to identify the suitable counterparts of the typical components of a continuous static monitoring system for a historical construction. The results of the research include a simple case-study, which is presented with low-cost, open-source, calibrated components, as well as an assessment of different alternatives for deploying basic structural health monitoring arrangements. The results of the research show the great potential of these existing technologies that may help to promote a widespread and cost-efficient monitoring of the built cultural heritage. Such scenario may contribute to the onset of commonplace digital records of historical constructions in an open-source, versatile and reliable fashion.Peer ReviewedPostprint (author's final draft

MASTER OF SCIENCE, FAMILY PRACTICE NURSEIn 2009, the Centers for Medicare & Medicaid (CMS), established “Meaningful Use”
regulations through an incentive program, as part of the American Recovery and Reinvestment
Act of 2009 (Gance-Cleveland, Gilbert, Gilbert, Dandreaux, & Russell, 2014). Meaningful Use
(MU) is tied to reimbursement and focuses on how the Electronic Health Record (EHR) is being
used (Center for Disease Control and Prevention, 2012). The goal of MU is to transform the use
of the EHR from a documentation tool, to a data reservoir which allows for meaningful reviews
and interpretations of the quality of care (Gance-Cleveland et al, 2014).Project / Background / Significance / Review of Literature / Problem Overview / Problem Statement / Purpose / Design / Method / Plan Do Study Act (PDSA) / Ethical Considerations / Significance to Nursing / Dissemination / Conclusion
Demographic Data for Development Decisionmaking: Case Studies From Ethiopia and Uganda
Analyzes the lack of demographic and socioeconomic data, limited access to and use of existing data, and insufficient demand for their application in policy making and resource allocation. Makes recommendations for greater access, demand, and use of data
Land use, urban, environmental, and cartographic applications, chapter 2, part D
Microwave data and its use in effective state, regional, and national land use planning are dealt with. Special attention was given to monitoring land use change, especially dynamic components, and the interaction between land use and dynamic features of the environment. Disaster and environmental monitoring are also discussed

Bank relationships and small firms’ financial performance
We examine the relationship between the number of bank relationships and firms’ performance, evaluating possible differential effects related to firms’ size. Our sample of firms from Italy includes many small firms, 99 percent of which are not listed and for which bank debt is a major source of financing. In the sample, 4 percent of the firms have a single bank relationship, and 66 percent of them have five or fewer relationships. We find that return on equity and return on assets decrease as the number of bank relationships increases, with a stronger relationship for small firms than for large firms. We also find that interest expense over assets increases as the number of relationships increases. Particularly for small firms, our results are consistent with analyses indicating that fewer bank relationships reduce information asymmetries and agency problems, which outweigh negative effects connected to holdup problems.
