The DECIDE Project: Designing and Implementing a Prototype Service for Supporting Early Diagnosis of Alzheimer's Disease

This paper will present the design and implementation challenges of the innovative DECIDE service, to support research and early diagnosis of Alzheimer’s and other neurodegenerative diseases. DECIDE service, which is based on a Grid eInfrastructure, offers a set of tools providing quantitative measurements, to help researchers and clinicians make more informed diagnosis. As the service specifically targets the clinical community, it differs significantly from other initiatives since it needs to comply with the requirements imposed by the clinical routine in terms of accuracy, robustness, ease of use, data handling policies, adherence to clinical praxis. Moreover, sustainability aspects will also be discussed, since DECIDE aims to propose such service as a reference at European level, possibly extending it to other pathologies. We will then summarize the main results obtained to date, and the possible future developments

The usability of open source software: analysis and prospects

Open source communities have successfully developed many pieces of software although most computer users only use proprietary applications. The usability of open source software is often regarded as one reason for this limited distribution. In this paper we review the existing evidence of the usability of open source software and discuss how the characteristics of open-source development influence usability. We describe how existing human-computer interaction techniques can be used to leverage distributed networked communities, of developers and users, to address issues of usability

Information for Impact: Liberating Nonprofit Sector Data

This paper explores the costs and benefits of four avenues for achieving open Form 990 data: a mandate for e-filing, an IRS initiative to turn Form 990 data into open data, a third-party platform that would create an open database for Form 990 data, and a priori electronic filing. Sections also discuss the life and usage of 990 data. With bibliographical references

Our Space: Online Civic Engagement Tools for Youth

Part of the Volume on Civic Life Online: Learning How Digital Media Can Engage YouthThe popularity of Facebook, MySpace, IM, and email with youth in developed countries demonstrates how second nature the online world has become for youth. People behind youth civic engagement initiatives are starting to see that the best way to engage youth is on their own terms and in the way they expect -- that is, online. With this in mind, this chapter examines the emerging world of online civic engagement sites for youth and by youth. Through a close examination of TakingITGlobal, an global online civic engagement site, combined with a landscape survey of sites with a mandate to civically engage youth, we present some initial findings on how youth are civically engaged and what it is they are actually doing on these sites

Enhanced Search for Educational Resources - A Perspective and a Prototype from ccLearn

Users of search tools who seek educational materials on the Internet are typically presented with either a web-scale search (e.g., Google or Yahoo) or a specialized, site-specific tool. The specialized search tools often rely upon custom data fields, such as user-entered ratings, to provide additional value. As currently designed, these systems are generally too labor intensive to manage and scale up beyond a single site or set of resources.However, custom (or structured) data of some form is necessary if search outcomes foreducational materials are to be improved. For example, design criteria and evaluative metrics are crucial attributes for educational resources, and these currently require human labeling and verification. Thus, one challenge is to design a search tool that capitalizes on available structured data (also called metadata) but is not crippled if the data are missing. This information should be amenable to repurposing by anyone, which means that it must be archived in a manner that can be discovered and leveraged easily.In this paper, we describe the extent to which DiscoverEd, a prototype developed by ccLearn, meets the design challenge of a scalable, enhanced search platform for educational resources. We then explore some of the key challenges regarding enhanced search for topic-specific Internet resources generally. We conclude by illustrating some possible future developments and third-party enhancements to the DiscoverEd prototype

Merging Special Collections with GIS Technology to Enhance the User Experience

This analysis evaluates how PhillyHistory.org merged their unique special collection materials with geospatial-based progressive technology to challenge and educate the global community. A new generation of technologically savvy researchers has emerged that expect a more enhanced user experience than earlier generations. To meet these needs, collection managers are collaborating with community and local institutions to increase online access to materials; mixing best metadata practices with custom elements to create map mashups; and merging progressive GIS technology and geospatial based applications with their collections to enhance the user experience. The PhillyHistory.org website was analyzed to explore how they used various geospatial technology to create a new type of digital content management system based on geographical information and make their collections accessible via online software and mobile applications
