    Tangible user interfaces : past, present and future directions

    In the last two decades, Tangible User Interfaces (TUIs) have emerged as a new interface type that interlinks the digital and physical worlds. Drawing upon users' knowledge and skills of interaction with the real non-digital world, TUIs show a potential to enhance the way in which people interact with and leverage digital information. However, TUI research is still in its infancy and extensive research is required in or- der to fully understand the implications of tangible user interfaces, to develop technologies that further bridge the digital and the physical, and to guide TUI design with empirical knowledge. This paper examines the existing body of work on Tangible User In- terfaces. We start by sketching the history of tangible user interfaces, examining the intellectual origins of this field. We then present TUIs in a broader context, survey application domains, and review frame- works and taxonomies. We also discuss conceptual foundations of TUIs including perspectives from cognitive sciences, phycology, and philoso- phy. Methods and technologies for designing, building, and evaluating TUIs are also addressed. Finally, we discuss the strengths and limita- tions of TUIs and chart directions for future research

    Demonstration farms

    The study aimed to review the concept of demonstration farms as a source of information for landscape architects. A review of agricultural history and the history of demonstration farms provided the context to current development. A range of types of demonstration farms were identified. These are presented as ten case studies and formed the basis of the information discussed. Four objectives for demonstration, production, landscape, education and recreation were considered. Trends in the development of these objectives are discussed independently. Overseas developments of historic farms and city farms are examined. The characteristics and effectiveness of demonstrations are considered. In the development of school farms, historic farms and farms which explain farming to the public, opportunities for landscape architects are indicated. Farms demonstrating production and landscape objectives are drawn together suggesting new directions for their joint development

    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

    Study of Population Dynamics of Sugarcane Aphid \u3ci\u3e(Melanaphis sacchari)\u3c/i\u3e in Rio Grande Valley, Texas

    Get PDF
    Chapter 1: This chapter incorporates detailed information about the biotype concept, aphids, their types and their biotypes, importance of studying insect biotypes and their role in mediating host plant defenses. Chapter 2: This chapter explains in detail about the biology, biotypes, feeding behavior, damage, and economic loss caused due to sugarcane aphid infestation. This chapter further elaborates on the need for studying population level differences and justifies the objectives and significance of this research study. Chapter 3: This chapter provides information about the comprehensive work done on three different populations of sugarcane aphid collected from three different locations in Rio Grande Valley, Texas. This chapter includes detail information on the life history traits and feeding behavior of three different sugarcane aphid populations along with host plant defense responses against post infestation of sugarcane aphids. Chapter 4: This chapter provides an overview of my major findings and possible future directions for research to understand the sugarcane aphids and the potential emergence of new biotype(s)

    Extending the Frontiers: Essays on the New Transatlantic Slave Trade Database

    Get PDF
    Since 1999, intensive research efforts have vastly increased what is known about the history of coerced migration of transatlantic slaves. A huge database of slave trade voyages from Columbus’s era to the mid-nineteenth century is now available on an open-access Web site, incorporating newly discovered information from archives around the Atlantic world. The groundbreaking essays in this book draw on these new data to explore fundamental questions about the trade in African slaves. The research findings—that the size of the slave trade was 14 percent greater than had been estimated, that trade above and below the equator was largely separate, that ports sending out the most slave voyages were not in Europe but in Brazil, and more—challenge accepted understandings of transatlantic slavery and suggest a variety of new directions for important further research

    \u3ci\u3eAMBYSTOMA\u3c/i\u3e: PERSPECTIVES ON ADAPTATION AND THE EVOLUTION OF VERTEBRATE GENOMES

    Get PDF
    Tiger salamanders, and especially the Mexican axolotl (Ambystoma mexicanum), are important model organisms in biological research. This dissertation describes new genomic resources and scientific results that greatly extend the utility of tiger salamanders. With respect to new resources, this dissertation describes the development of expressed sequence tags and assembled contigs, a comparative genome map, a web-portal that makes genomic information freely available to the scientific community, and a computer program that compares structure features of organism genomes. With respect to new scientific results, this dissertation describes a quantitative trait locus that is associated with ecologically and evolutionarily relevant variation in developmental timing, the evolutionary history of the tiger salamander genome in relation to other vertebrate genomes, the likely origin of amniote sex chromosomes, and the identification of the Mexican axolotl sex-determining locus. This dissertation is concluded with a brief outline of future research directions that can extend from the works that are presented here
