ScreenTrack: Using a Visual History of a Computer Screen to Retrieve Documents and Web Pages

Computers are used for various purposes, so frequent context switching is inevitable. In this setting, retrieving the documents, files, and web pages that have been used for a task can be a challenge. While modern applications provide a history of recent documents for users to resume work, this is not sufficient to retrieve all the digital resources relevant to a given primary document. The histories currently available do not take into account the complex dependencies among resources across applications. To address this problem, we tested the idea of using a visual history of a computer screen to retrieve digital resources within a few days of their use through the development of ScreenTrack. ScreenTrack is software that captures screenshots of a computer at regular intervals. It then generates a time-lapse video from the captured screenshots and lets users retrieve a recently opened document or web page from a screenshot after recognizing the resource by its appearance. A controlled user study found that participants were able to retrieve requested information more quickly with ScreenTrack than under the baseline condition with existing tools. A follow-up study showed that the participants used ScreenTrack to retrieve previously used resources and to recover the context for task resumption.Comment: CHI 2020, 10 pages, 7 figure

The impact of History teaching/learning resources on student performance in KCSE History examinations: A case of Tigania and Igembe districts Meru County, Kenya

This study set to establish the impact which influenced academic performance in Kenya Certificate of Secondary Education (KCSE) History examination in Tigania and Igembe Districts, Meru County Kenya. This study aimed at establishing how learning and teaching resources impact on performance in Kenya Certificate of Secondary Education (KCSE) History examination in Tigania and Igembe Districts, Meru County Kenya. The study covered the period between 2005 and 2009. It involved public and private secondary schools (mixed and single sex, boarding and day school). The study was conducted using descriptive survey design. The study used probability sampling where simple random sampling was employed. The collection of data was done using questionnaires for head teachers and teachers, interview guide for parents, and focus group discussion with form three History students. The data was analyzed using statistical package for social sciences (SPSS) computer program and descriptive statistics. Chi square was used to test the null hypotheses. It was found that teaching-learning resources are statistically significant in learning and teaching of History. From the findings, most schools in the two districts (75%) lacked a library and of those schools which have a library only 18.2% are adequately stocked with History learning /teaching resources. Key Words: Learning/Teaching Resources on student performance, Tigania and Igembe Districts

The value of teaching history with technology -- a professor's evolution

Thesis (Ed.D.)--Boston UniversityThis study examined the added value technology in the form of computer-based resources brought to the teaching of history of an experienced, tenured university history professor. This added value was measured by following the evolution of this history professor's adoption of computer-based resources in teaching. During his evolution the use of technology enhanced Dr. K. 's ability to deliver, explain and deepen the meaning of complicated historical lessons. From summer 2000 to summer 2003 the researcher helped design, develop and create computer-based resources for two history classes at a large northeastern U.S. urban university taught by this fulltime history professor. The researcher also oversaw the implementation, which involved the layering of those multimedia resources. In 2001, some of the computer-based resources developed for these classes were also partially implemented at a nearby urban high school. Overall the lectures were all put into Microsoft Power Point slides. They included audio clips (WAV) and video clips (AVI, WMV). Some slides also included animations that were created in Macromedia Flash. Other animations were created within Microsoft Power Point to help understanding of elaborate dynamic processes

Are all reversible computations tidy?

It has long been known that to minimise the heat emitted by a deterministic computer during it's operation it is necessary to make the computation act in a logically reversible manner\cite{Lan61}. Such logically reversible operations require a number of auxiliary bits to be stored, maintaining a history of the computation, and which allows the initial state to be reconstructed by running the computation in reverse. These auxiliary bits are wasteful of resources and may require a dissipation of energy for them to be reused. A simple procedure due to Bennett\cite{Ben73} allows these auxiliary bits to be "tidied", without dissipating energy, on a classical computer. All reversible classical computations can be made tidy in this way. However, this procedure depends upon a classical operation ("cloning") that cannot be generalised to quantum computers\cite{WZ82}. Quantum computations must be logically reversible, and therefore produce auxiliary qbits during their operation. We show that there are classes of quantum computation for which Bennett's procedure cannot be implemented. For some of these computations there may exist another method for which the computation may be "tidied". However, we also show there are quantum computations for which there is no possible method for tidying the auxiliary qbits. Not all reversible quantum computations can be made "tidy". This represents a fundamental additional energy burden to quantum computations. This paper extends results in \cite{Mar01}.Comment: 7 pages, 1 figure ep

Assessing the Effect of High Performance Computing Capabilities on Academic Research Output

This paper uses nonparametric methods and some new results on hypothesis testing with nonparametric efficiency estimators and applies these to analyze the effect of locally-available high performance computing (HPC) resources on universities efficiency in producing research and other outputs. We find that locally-available HPC resources enhance the technical efficiency of research output in Chemistry, Civil Engineering, Physics, and History, but not in Computer Science, Economics, nor English; we find mixed results for Biology. Out research results provide a critical first step in a quantitative economic model for investments in HPC

So you want to be part of it? CAL Resources for New York’s Lower East Side

First paragraph: This article reviews a number of computer-assisted learning (CAL) resources intended for use in teaching American social history of the late nineteenth-century and early twentieth centuries: first, a tutorial package on the socially sensitive photography of the progressive reformer, Jacob Riis; second, an impressive, self-contained dataset, based on the 1900 census, relating to the composition and nature of immigrant communities on New York's Lower Eastside; and third, a range of websites that provide public access to hypertext materials on urban life. Similar such reviews have appeared in previous issues of Craft and our objectives remain straightforward and functional. Our initial purpose was to assess these resources on their own terms, as teaching aids, and, as with any textual source, assess their contribution to the study of U.S. social history. But there were more practical considerations, however: whether any of these resources could be integrated into existing courses in American history at Stirling University, either with or without some modification to the curricula and teaching methods. Inevitably, the exercise raised some wider pedagogic issues, including whether cognitive problems pertaining to the use of visual images generally are too readily ignored by teachers and lecturers

Introduction to the Special Issue on Human Resource Information Systems and Human Computer Interaction

In this special issue, we focus on the role that human-computer interaction (HCI) can play in the development and successful use of human resource information systems (HRIS) in organizations. There is no doubt that information systems have transformed the practice of human resources. From online/e-recruiting to e-learning and the growing interest in data analytics, the practice of human resources has become technology centric. Given the overlap of human resource practice and information systems, both fields need to work together to develop models and theories that advance the practice of HRIS in organizations. Therefore, this special issue a) briefly reviews the history of the HRIS field, b) advances theory and research that stands at the intersection of HRIS and HCI, and c) suggest new directions for research at the intersection of HRIS and HCI
