    Introduction: The Third International Conference on Epigenetic Robotics

    This paper summarizes the paper and poster contributions to the Third International Workshop on Epigenetic Robotics. The focus of this workshop is on the cross-disciplinary interaction of developmental psychology and robotics. Namely, the general goal in this area is to create robotic models of the psychological development of various behaviors. The term "epigenetic" is used in much the same sense as the term "developmental" and while we could call our topic "developmental robotics", developmental robotics can be seen as having a broader interdisciplinary emphasis. Our focus in this workshop is on the interaction of developmental psychology and robotics and we use the phrase "epigenetic robotics" to capture this focus

    Humanoid Theory Grounding

    In this paper we consider the importance of using a humanoid physical form for a certain proposed kind of robotics, that of theory grounding. Theory grounding involves grounding the theory skills and knowledge of an embodied artificially intelligent (AI) system by developing theory skills and knowledge from the bottom up. Theory grounding can potentially occur in a variety of domains, and the particular domain considered here is that of language. Language is taken to be another “problem space” in which a system can explore and discover solutions. We argue that because theory grounding necessitates robots experiencing domain information, certain behavioral-form aspects, such as abilities to socially smile, point, follow gaze, and generate manual gestures, are necessary for robots grounding a humanoid theory of language

    Ongoing Emergence: A Core Concept in Epigenetic Robotics

    Get PDF
    We propose ongoing emergence as a core concept in epigenetic robotics. Ongoing emergence refers to the continuous development and integration of new skills and is exhibited when six criteria are satisfied: (1) continuous skill acquisition, (2) incorporation of new skills with existing skills, (3) autonomous development of values and goals, (4) bootstrapping of initial skills, (5) stability of skills, and (6) reproducibility. In this paper we: (a) provide a conceptual synthesis of ongoing emergence based on previous theorizing, (b) review current research in epigenetic robotics in light of ongoing emergence, (c) provide prototypical examples of ongoing emergence from infant development, and (d) outline computational issues relevant to creating robots exhibiting ongoing emergence

    This paper explores a number of important issues surrounding the certification of work-based learning (known as accreditation in the UK) for the award of university level qualifications. The paper is divided into two main sections. Section one of the paper defines, and explores the historical development of work-based certification and qualifications in the UK. This is followed in section two by defining various types of certification that are open to organizations, drawing upon real life case histories. The paper concludes by highlighting a number of factors certificating institutions and potential clients should consider when entering the certification marketplace

    Evaluation of National Institute of Learning Development (NILD) and Discovery Educational Therapy Program

    Get PDF
    This qualitative study evaluated the NILD and Discovery Therapy Educational Program at one Christian school, for effectiveness and academic progress of students with learning disabilities (LD) who receive the therapy. This study leads to positive social change as leaders of Christian schools and parents see the need and provide interventional programs for LD students.https://scholarworks.waldenu.edu/archivedposters/1075/thumbnail.jp

    Towards a Theory Grounded Theory of Language

    Get PDF
    In this paper, we build upon the idea of theory grounding and propose one specific form of theory grounding, a theory of language. Theory grounding is the idea that we can imbue our embodied artificially intelligent systems with theories by modeling the way humans, and specifically young children, develop skills with theories. Modeling theory development promises to increase the conceptual and behavioral flexibility of these systems. An example of theory development in children is the social understanding referred to as “theory of mind.” Language is a natural task for theory grounding because it is vital in symbolic skills and apparently necessary in developing theories. Word learning, and specifically developing a concept of words, is proposed as the first step in a theory grounded theory of language

    Parent Perceptions of Post-Secondary Programming Completed by Their Adult Children with Autism Spectrum Disorder

    Get PDF
    Texas Tech University\u27s Burkhart Center for Autism Education and Research works with communities & families in the greater West Texas area to provide supports and services to individuals with Autism Spectrum Disorder with a primary focus on building independent living and vocational skills in a post-secondary environment. In this study, parents of individuals with ASD who had completed the Burkhart Center’s Transition Academy completed an online survey. Parents identified areas in which they were satisfied with their child’s post-secondary experience as well as dissatisfaction, and of additional need. The findings of this current study may provide critical information to post-secondary programs who work with students with ASD

    Expression of Human CD4 and chemokine receptors in cotton rat cells confers permissiveness for productive HIV infection

    <p>Abstract</p> <p>Background</p> <p>Current small animal models for studying HIV-1 infection are very limited, and this continues to be a major obstacle for studying HIV-1 infection and pathogenesis, as well as for the urgent development and evaluation of effective anti-HIV-1 therapies and vaccines. Previously, it was shown that HIV-1 can infect cotton rats as indicated by development of antibodies against all major proteins of the virus, the detection of viral cDNA in spleen and brain of challenged animals, the transmission of infectious virus, albeit with low efficiency, from animal to animal by blood, and an additional increase in the mortality in the infected groups.</p> <p>Results</p> <p>Using <it>in vitro </it>experiments, we now show that cotton rat cell lines engineered to express human receptor complexes for HIV-1 (hCD4 along with hCXCR4 or hCCR5) support virus entry, viral cDNA integration, and the production of infectious virus.</p> <p>Conclusion</p> <p>These results further suggest that the development of transgenic cotton rats expressing human HIV-1 receptors may prove to be useful small animal model for HIV infection.</p
