Robot Composite Learning and the Nunchaku Flipping Challenge
Advanced motor skills are essential for robots to physically coexist with
humans. Much research on robot dynamics and control has achieved success on
hyper robot motor capabilities, but mostly through heavily case-specific
engineering. Meanwhile, in terms of robot acquiring skills in a ubiquitous
manner, robot learning from human demonstration (LfD) has achieved great
progress, but still has limitations handling dynamic skills and compound
actions. In this paper, we present a composite learning scheme which goes
beyond LfD and integrates robot learning from human definition, demonstration,
and evaluation. The method tackles advanced motor skills that require dynamic
time-critical maneuver, complex contact control, and handling partly soft
partly rigid objects. We also introduce the "nunchaku flipping challenge", an
extreme test that puts hard requirements to all these three aspects. Continued
from our previous presentations, this paper introduces the latest update of the
composite learning scheme and the physical success of the nunchaku flipping
challenge

Hands on - hands off: on hitting your thumb with a virtual hammer
In a wired world even the most physically embodied craft skills are affected by computer facilitated communication. To consider how different sorts of space â both real and virtual â influence the learning of craft skills this paper presents three types of space â the ârealâ space of a jewellery workshop, an online âwikiâ space for learning how to make a folding knife mediated by face to face interaction and an online discussion group about French Horn making. Some features common to the learning of any craft skill are discussed as well as some current ideas about the influence of networked communication on the way people relate to each other. Conclusions are drawn about the relationships between different types of learner, different types of skill and different types of learning space which demonstrate that while there may be no substitute for face to face contact in learning the most embodied craft skills, even in real-world settings a significant proportion of learning depends on social interaction which may be reproduced online.

Integrating Essential Elements of Person-Centered Transition Planning Practices Into the Development of the Individualized Education Program With All Students with Disabilities
This is the second of two white papers that were developed to look at the potential for integrating a person-centered approach into the design and implementation of transition planning with individuals with disabilities in high school across nine demonstration sites in New York State. While the first paper, Infusing a Person-Centered Approach into Transition Planning for Students with Developmental Disabilities, 2001, looked at the barriers present within and between systems of support, this paper provides a deeper view of the strategies, methods and approaches that proved to be effective in supporting and/or sustaining person-centered practices within the Individualized Education Program (IEP) process. Through an emphasis on the need to utilize post-school outcomes as a basis for transition planning, a real example is provided to highlight the contrast between the use of person-centered practices in the development of an IEP and the use of typical special education programming. A model that overlays person-centered practices into the existing IEP process is suggested along with several suggestions proven effective in leading to seamless transition across the school experience. The paper concludes with a review of the data across the project life (1998-2000) identifying the accomplishments and challenges experienced by project participants, as well as overall recommendations to the field
Cost-Effective Extracorporeal Membrane Oxygenation Simulation

For further information see: https://creativecommons.org/licenses/by-nc-nd/4.0/This invited review article was presented orally on the occasion of the South West Asian Chapter conference of the Extracorporeal Life Support Organization (ELSO) held in New Delhi, India in January 2018. It has an educational focus on the topic of extracorporeal membrane oxygenation (ECMO), which is increasingly being used as a lifesaving bridge therapy. A case is being made regarding the adage âpractice makes perfectâ to be considered in the context of simulation-based education to ensure patient safety. Technology-enhanced simulation-based deliberate practice should be used more commonly to support clinicians in the development of all their professional skills. This is an ethical imperative that may be addressed using low-cost simulation modalities that are sometimes proven to be as effective as more expensive approaches. Educators can now design their programs according to published best practice standards for the benefit of their learners, and ultimately the patients they care for. Simulation-based education clearly has a place and important role to play in preparing ECMO teams dealing with routine procedures as well as emergency situations. Several solution and approaches are being presented alongside innovative work currently being done in collaboration between a regional ELSO center of excellence and an academic institution. This innovative simulator is composed of several modules serving different functions required for the simulation of ECMO emergencies at a much lower cost than using the real machine and its various expensive disposable components.Peer reviewedFinal Published versio
Robot Autonomy for Surgery
Autonomous surgery involves having surgical tasks performed by a robot
operating under its own will, with partial or no human involvement. There are
several important advantages of automation in surgery, which include increasing
precision of care due to sub-millimeter robot control, real-time utilization of
biosignals for interventional care, improvements to surgical efficiency and
execution, and computer-aided guidance under various medical imaging and
sensing modalities. While these methods may displace some tasks of surgical
teams and individual surgeons, they also present new capabilities in
interventions that are too difficult or go beyond the skills of a human. In
this chapter, we provide an overview of robot autonomy in commercial use and in
research, and present some of the challenges faced in developing autonomous
surgical robots
The fourth dimension: A motoric perspective on the anxietyâperformance relationship
This article focuses on raising concern that anxietyâperformance relationship theory has insufficiently catered for motoric issues during, primarily, closed and self-paced skill execution (e.g., long jump and javelin throw). Following a review of current theory, we address the under-consideration of motoric issues by extending the three-dimensional model put forward by Cheng, Hardy, and Markland (2009) (âToward a three-dimensional conceptualization of performance anxiety: Rationale and initial measurement development, Psychology of Sport and Exercise, 10, 271â278). This fourth dimension, termed skill establishment, comprises the level and consistency of movement automaticity together with a performer's confidence in this specific process, as providing a degree of robustness against negative anxiety effects. To exemplify this motoric influence, we then offer insight regarding current theoriesâ misrepresentation that a self-focus of attention toward an already well-learned skill always leads to a negative performance effect. In doing so, we draw upon applied literature to distinguish between positive and negative self-foci and suggest that on what and how a performer directs their attention is crucial to the interaction with skill establishment and, therefore, performance. Finally, implications for skill acquisition research are provided. Accordingly, we suggest a positive potential flow from applied/translational to fundamental/theory-generating research in sport which can serve to freshen and usefully redirect investigation into this long-considered but still insufficiently understood concept
Implementation Science and Fidelity Measurement: A Test of the 3-5-7 Modelâ˘
Children and youths engaged with the child welfare system can experience grief and loss as a result of trauma, broken relationships, and inadequate attachments. Interventionists are often challenged to implement effective strategies that help youths to reestablish trusting relationships and to promote overall psychological well-being. A 5-year federal demonstration project funded by the U.S. Department of Health and Human Services, Childrenâs Bureau, guided by an implementation science model, sought to increase well-being in youths age 12â21 who were involved in the child welfare system. The 3-5-7 Modelâ˘, a strengths-based approach that empowers children, youths, and families to engage in grieving and integrating significant relationships, was studied. A fidelity system was created in order to test the model. Important lessons about implementation science guided the work of the demonstration project. Although definitive conclusions could not be reached, several indicators of psychological well-being were found to be associated with high levels of fidelity to the 3-5-7 ModelTM. Suggestions for future research are offered
