This chapter discusses a bottom-up design strategy to support the principles of Universal Design and Universal Design for Learning adapted for online course development. The concept of Universal Design demands a holistic, bottom-up instructional design model for online course development that integrates technology, accessibility, recent instructional and learning theories, and a participatory postmodern worldview. This study is intended for faculty, instructional designers, administrators, assistive technology staff, and Web multimedia software vendors associated with higher education. The research assists these target audiences to design and develop online courses that are accessible without special adaptation or modification. The components of Universal Design for online learning support newer emergent approaches to instructional design, various programming solutions used in the software engineering field for efficiency, Universal Design for Learning, and legal guidelines associated with accessibility.

Pew and Mavor (1998) called for an integrative representation of human behavior for use in models of individual combatants and organizations. Models with integrated representation of behavior have only been achieved at rudimentary levels according to those performing the studies (e.g. Pew & Mavor, 1998; Tulving, 2002) and those building the models (e.g. Warwick et al., 2002). This chapter will address aspects of cognitive performance that are important to incorporate into models of combat based on acceptance of theory, strength of empirical data, or for other reasons such as to bridge gaps where incomplete knowledge exists about cognitive behavior and performance. As a starting point, this chapter will assess which of Pew and Mavor’s recommendations are still appropriate as determined by a review of selected literature on cognition and its representation. We will also provide some review and extensions of key literature on cognition and modeling and suggest a way ahead to close the remaining gaps. Different aspects of cognition are described with recent findings, and most are followed by an example of how they have been represented in computer models or a discussion of challenges to their representation in modeling.

The chapter provides instruction on how public libraries can improve the services that they provide to community members with print-related disabilities.

A combination of methods was used (interview, survey, document analysis, usability testing, and expert inspection), to investigate the current level of service provided to community members who are blind or low vision by the Baltimore County Public Library, in five areas:

1. Web Accessibility and Maintenance

2. Staff Awareness and Training

3. Physical Environment of the Library

4. Library offerings, including databases, materials, and equipment: what we have now and what we should have

5. Marketing materials: what, how, and where to be more visible

In all five areas, there were important findings about current barriers to accessibility, and suggestions for improvement in the future were made in the chapter.

The chapter details the steps taken by a large public library system, in a challenging budget environment, with changing leadership, to make improvements in the quality of service provided to people who are blind or low vision.

In the past, people with print-related disabilities were often referred to the Maryland State Library for the Blind and Physically Handicapped. However, over time, the nature of materials acquisitions at public libraries has changed. A large percentage of materials acquired by public libraries is now in digital format, which provides an opportunity for public libraries to start providing services to people with print disabilities.

Digital inclusivity is about making web sites available to users regardless of a user’s device or disability. This study seeks to find out how accessible and mobile ready state library web sites are and if there is a relationship between web site accessibility and mobile readiness.

I examined web site accessibility through automated code evaluation and manual code inspection of the web site homepage. I evaluated mobile readiness by comparing how homepages displayed on a desktop computer vs. a smart phone.

Most state library web sites had accessibility problems, including missing alternative text for images (82%), inaccessible forms (54%), and poor contrast between text and background (56%). Only 36% of the sites were mobile ready. A Spearman rho analysis of accessibility and mobile readiness found that the more accessible a site is, the more likely it is mobile ready (and vice versa).

While this study identified accessibility and mobile readiness issues, it does not address why these problems exist. In addition, the unit of analysis was limited to the web site homepage. The study’s results emphasize the need to combine manual code inspection with automated analysis, particularly for images’ alternative text.

The study suggests that state libraries need to take greater care in meeting accessibility standards, particularly easily followed standards such as providing appropriate alternative text for images.

Despite the importance of state libraries in organizing and funding local libraries, there has been little research to date on state library web sites.

This chapter draws on analysis of the spatial and material configuration as well as analysis of use to establish whether and how open spaces contribute to an increased spatial justice in Comuna 13. Location, and visual and physical accessibility have been found to be limiting factors for the spaces’ usability by diverse user groups. Regulations and management issues have also been found to be highly influential on the sites’ usability, the diversity of its users or the regulation of behaviour deemed ‘inappropriate’, such as informal trade. On the other hand, design and spatial organisation into subspaces increased the spaces’ usability and accessibility for a diversity of user groups, thus increasing spatial justice. Analysis of use underlines the multifunctionality of people’s everyday spaces for pedestrian traffic, recreation and socialising as well as informal trade. It also shows that not all new spaces are accepted equally, and that new spaces fall into disuse especially if they fail to provide a design and functionality that relate to people’s everyday activities.

Purpose — To develop methodologies to evaluate search engines according to an individual's preference in an easy and reliable manner, and to formulate user-oriented metrics to compare freshness and duplication in search results.

Design/methodology/approach — A personalised evaluation model for comparing search engines is designed as a hierarchy of weighted parameters. These commonly found search engine features and performance measures are given quantitative and qualitative ratings by an individual user. Furthermore, three performance measurement metrics are formulated and presented as histograms for visual inspection. A methodology is introduced to quantitatively compare and recognise the different histogram patterns within the context of search engine performance.

Findings — Precision and recall are the fundamental measures used in many search engine evaluations due to their simplicity, fairness and reliability. Most recent evaluation models are user oriented and focus on relevance issues. Identifiable statistical patterns are found in performance measures of search engines.

Research limitations/implications — The specific parameters used in the evaluation model could be further refined. A larger scale user study would confirm the validity and usefulness of the model. The three performance measures presented give a reasonably informative overview of the characteristics of a search engine. However, additional performance parameters and their resulting statistical patterns would make the methodology more valuable to the users.

Practical implications — The easy-to-use personalised search engine evaluation model can be tailored to an individual's preference and needs simply by changing the weights and modifying the features considered. A user is able to get an idea of the characteristics of a search engine quickly using the quantitative measure of histogram patterns that represent the search performance metrics introduced.

Originality/value — The presented work is considered original as one of the first search engine evaluation models that can be personalised. This enables a Web searcher to choose an appropriate search engine for his/her needs and hence finding the right information in the shortest time with the least effort.
