For a given target node T and a given depth k ≥ 1, we propose an algorithm for discovering a local causal network around the target T to depth k. In our algorithm, we find parents, children and some descendants (PCD) of nodes stepwise away from the target T until all edges within the depth k local network cannot be oriented further. Our algorithm extends the PCD-by-PCD algorithm for prediction ...
Welcome to Volume 9 of Preventing Chronic Disease: Public Health Research, Practice, and Policy (PCD). Each year, I review our progress and articulate our plans for the next year, and I am excited to report that we have accomplished what we set out to do this past year and more. In 2012, we will realize the results of working during the past 2 years to accelerate our production process and more...
This paper presents comparisons among three item-selection criteria for the sequential probability ratio test. The criteria were compared in terms of their efficiency in selecting items, as indicated by average test length (ATL) and the percentage of correct decisions (PCD). The item-selection criteria applied in this study were the Fisher information function, the KullbackLeibler information f...
We propose a method-independent process model of user-centred design (UCD). It is based on recognised sources and its structure was developed in a set of assessments in industrial settings. The result is a process model that identifies six main processes of UCD. Each of these is defined through a set of outcomes. The model makes tangible the interface between the usability engineering and desig...
In this paper, we characterize the computational power of dynamical systems with piecewise constant derivatives (PCD) considered as computational machines working on a continuous real space with a continuous real time: we prove that piecewise constant derivative systems recognize precisely the languages of the ω th (respectively: ω + 1 th ) level of the hyper-arithmetical hierarchy in dimension...
This case study addresses how we applied user centered design (UCD) to the software development lifecycle for the new City of Austin Utilities Online Customer Care website. The case study focuses on the use of personas, prototypes, and user testing, discusses what worked well, and provides lessons learned.
This issue of Preventing Chronic Disease (PCD) illustrates some of the breadth of work in chronic disease prevention being undertaken throughout the world. The wide range of activity includes health promotion, descriptive epidemiology, behavioral risk-factor surveillance, and purely exploratory and descriptive research. The emphasis of this issue is on efforts being made in economically lessdev...
In this paper, we present a complete computational pipeline for extracting a compact shape descriptor for curve point cloud data (PCD). Our shape descriptor, called a barcode, is based on a blend of techniques from differential geometry and algebraic topology. We also provide a metric over the space of barcodes, enabling fast comparison of PCDs for shape recognition and clustering. To demonstra...
Rural ICT initiatives in India are not a new phenomenon. Identifying the performance attributes of these initiatives and preparing a road map for e-governance projects is essential. Any successful ICT initiative should undergo “user-centered design” process. But the real task is to create a useable “demand driven” ICT initiative for the rural sector. Scaling up of these chosen initiatives is an...
Privacy directly concerns the user as the data owner (datasubject) and hence privacy in systems should be implemented in a manner which concerns the user (user-centered). There are many concepts and guidelines that support development of privacy and embedding privacy into systems. However, none of them approaches privacy in a usercentered manner. Through this research we propose a framework tha...
