Promoting Latino self-management through use of information visualizations: A case study in New York City

Social determinants of health, including low health literacy and limited English proficiency, and other factors place Latinos at high risk for health disparities related to chronic diseases. Such diseases require self-management skills as well as medical management. Well-designed visualizations are suitable for visualizing data related to self-management because they can help narrow the comprehension gap between individuals with low and high levels of health literacy by leveraging existing visual analysis skills while reducing the demand on literacy and numeracy competencies. Use of information visualizations also supports a common visual representation across languages to address limited English proficiency. This report illustrates the use of information visualizations for communication related to self-management through research-based case examples and summarizes key lessons from studies with Latinos in New York City.

De l’analyse à la présentation. La visualisation d’informations pour la réification des questions et la re-énaction des idées dans l’analyse visuelle des données

We discuss the use of information visualization in digital sociology, (particularly in Controversy Mapping), and its role in outlining issues and objects of study through progressive insights. We believe the differences in visualizations between analysis and presentation are better understood as linked by a chain of transformations, rather than as two separate and stable levels of representation. We propose that, through such chain, two research movements are performed: the reification of issues, related to the construction of a stable consensus, and the reenaction of insights, that points to the role of visualizations as communication tools. We will illustrate such movements and effects by using a few examples of visualizations produced in the EMAPS research project.

Effects of Information Visualization on Older Adults' Decision-Making Performance in a Medicare Plan Selection Task: A Comparative Usability Study.

BackgroundTechnology gains have improved tools for evaluating complex tasks by providing environmental supports (ES) that increase ease of use and improve performance outcomes through the use of information visualizations (info-vis). Complex info-vis emphasize the need to understand individual differences in abilities of target users, the key cognitive abilities needed to execute a decision task, and the graphical elements that can serve as the most effective ES. Older adults may be one such target user group that would benefit from increased ES to mitigate specific declines in cognitive abilities. For example, choosing a prescription drug plan is a necessary and complex task that can impact quality of life if the wrong choice is made. The decision to enroll in one plan over another can involve comparing over 15 plans across many categories. Within this context, the large amount of complex information and reduced working memory capacity puts older adults’ decision making at a disadvantage. An intentionally designed ES, such as an info-vis that reduces working memory demand, may assist older adults in making the most effective decision among many options.ObjectiveThe objective of this study is to examine whether the use of an info-vis can lower working memory demands and positively affect complex decision-making performance of older adults in the context of choosing a Medicare prescription drug plan.MethodsParticipants performed a computerized decision-making task in the context of finding the best health care plan. Data included quantitative decision-making performance indicators and surveys examining previous history with purchasing insurance. Participants used a colored info-vis ES or a table (no ES) to perform the decision task. Task difficulty was manipulated by increasing the number of selection criteria used to make an accurate decision. A repeated measures analysis was performed to examine differences between the two table designs.ResultsTwenty-three older adults between the ages of 66 and 80 completed the study. There was a main effect for accuracy such that older adults made more accurate decisions in the color info-vis condition than the table condition. In the low difficulty condition, participants were more successful at choosing the correct answer when the question was about the gap coverage attribute in the info-vis condition. Participants also made significantly faster decisions in the info-vis condition than in the table condition.ConclusionsReducing the working memory demand of the task through the use of an ES can improve decision accuracy, especially when selection criteria is only focused on a single attribute of the insurance plan.

A Survey on Information Visualization for Network and Service Management

Network and service management encompasses a set of activities, methods, procedures, and tools, whose ultimate goal is to guarantee the proper functioning of a networked system. Computational tools are essential to help network administrators in their daily tasks, and information visualization techniques are of great value in such context. In essence, information visualization techniques associated to visual analytics aim at facilitating the tasks of network administrators in the process of monitoring and maintaining the network health. This paper surveys the use of information visualization techniques as a tool to support the network and service management process. Through a systematic literature review (SLR), we provide a historical overview and discuss the current state of the art in the field. We present a classification of 285 articles and papers from 1985 to 2013, according to an information visualization taxonomy, as well as a network and service management taxonomy. Finally, we point out future research directions and opportunities regarding the use of information visualization in network and service management.

A temporal analysis of institutional repository research

Due to the vast array of fields that use or have used institutional repositories, and the varying degrees of technology used, it is important to identify the development of the field, institutional repositories, in order to understand the breadth and depth of studies involved. This longitudinal study of the subject terms associated with published journal articles allows for a clearer understanding of the field of institutional repositories as it developed, evolved, and changed over time. This study's uniqueness lies in its longitudinal nature, and its use of information visualization, multidimensional scaling, and parallel coordinate analysis provide information regarding the field of institutional repositories. The multidimensional scaling and parallel coordinate analysis in conjunction with temporal analysis reveal that institutional repositories transitioned through several development phases. Future studies of institutional repositories will most likely discover evaluation tactics and potential guidelines, resulting in a need for additional case studies. Observations from the parallel coordinate analysis reveal three major themes. The first theme is the maturity of institutional repositories as a field over time, the second is the fluctuation and developmental status of institutional repositories until 2010---2013 (Period IV), and the third theme is the emergence of the discipline information science and library science as the strong generator of institutional repository research. Through the visualization and temporal analysis, information was gained regarding the history, development, and future studies within institutional repositories.

DBA\'s Perspective on Use of Information Visualization in Electronic Health Records

DBA's perspective for Information Visualization (IV) assists in providing a detailed insight about patient history in Electronic Health Records (EHR). These data visualizations are used by different stake holders in public hospitals such as Doctors, Database Administrators (DBA) and visual designers in order to improve health services for patients. This is not possible without the contribution of DBAs, who are directly involved in launching efficient query system and required data retrieval for resulting visualization. EHR database is comprising of different forms of data i.e., numbers, texts, pictures and graphs resulting in a challenge for creating a meaningful visualization for single or multiple patients. DBAs have EHR knowledge gaps, lesser exposure to the transformation process of data into effective visualization and understanding about IV limitations result in poor and less efficient IV tools. This study highlights the challenging factors that affect DBAs in understanding, developing and controlling EHR visualization. These factors are selected after a literature review and further analysis by a questionnaire based study on DBAs in two different government hospitals. This will help in highlighting the limitations of DBAs skills and experience and assist in determining the contribution of their role in the development of future IV applications. This work is a second phase of our ongoing research for designing a model, CARE 1.0, as a future IV solution in multiple EHR.

Visualization of educational information with the use services of cloud technology

The purpose of the paper is the theoretical justification for the use of information visualization with the use services of cloud technology in educational process secondary school. Object of research supports the educational process in secondary school. The object is to use visualization training information with the use services of cloud technology. The feasibility of the use of these technologies in education due to their compliance psychological peculiarities inherent in the present generation of students and the need for a compact representation of the training material in the manner most convenient to its perception, understanding, learning and remembering. It is shown that the use of visualization develops cognitive interest of students, makes it possible to create a positive emotional atmosphere in the classroom and facilitates implementation of intersubject connections in learning. However, visualization is a powerful didactic tool, the use of which has to be motivated, pedagogically appropriate methodically backed up. In our opinion, the problem of training of future teachers to effective use of technology of visualization in teaching activities is a perspective direction for further research.

Transient or permanent fisheye views: A comparative evaluation of source code interfaces

Transient use of information visualization may support specific tasks without permanently changing the user interface. Transient visualizations provide immediate and transient use of information visualization close to and in the context of the user’s focus of attention. Little is known, however, about the benefits and limitations of transient visualizations. We describe an experiment that compares the usability of a fisheye view that participants could call up temporarily, a permanent fisheye view, and a linear view: all interfaces gave access to source code in the editor of a widespread programming environment. Fourteen participants performed varied tasks involving navigation and understanding of source code. Participants used the three interfaces for between four and six hours in all. Time and accuracy measures were inconclusive, but subjective data showed a preference for the permanent fisheye view. We analyse interaction data to compare how participants used the interfaces and to understand why the transient interface was not preferred. We conclude by discussing seamless integration of fisheye views in existing user interfaces and future work on transient visualizations.

Mapping Scientometrics (1981–2001)

AbstractWe investigate an integrated approach to scientometric studies with emphasis to the use of information visualization and animation techniques. This study draws upon citation and co‐citation patterns derived from articles published in the journal Scientometrics (1981–2001). The modeling and visualization takes an evolutionary and historical perspective. The design of the visualization model adapts a virtual landscape metaphor with document co‐citation networks as the base map and annual citation rates as the thematic overlay. The growth of citation rates is presented through an animation sequence of the landscape model. Issues concerning the visual‐spatial design are discussed from a citation analysis point of view.
