Command/response protocols and concurrent software

A version of the program to control the parallel jaw gripper is documented. The parallel jaw end-effector hardware and the Intel 8031 processor that is used to control the end-effector are briefly described. A general overview of the controller program is given and a complete description of the program's structure and design are contained. There are three appendices: a memory map of the on-chip RAM, a cross-reference listing of the self-scheduling routines, and a summary of the top-level and monitor commands

A software toolbox for robotics

A system of programs was developed to simulate the concurrent command/response interaction between a parallel jaw end effector and the LISP program controlling it. The overall structure of the simulation system was described in a paper submitted to the IEEE Conference on Automation and Robotics. A user's guide for the system was written. A line numbering program on the VAX (Pascal), a program for aiding in file transfer from the VAX to an LSI11 over the RTNET (FORTRAN), and a file scanning program (a crude SCAN) for the LSI11 (FORTRAN) were also developed

Ergometer

An ergometer is described that has a pedal driven direct current motor as a load and includes a frame for supporting the body of a person in either a sitting or a prone position. The pedals may be operated by either the feet or the hands. The electrical circuitry of the ergometer includes means for limiting the load applied to the pedals as a function of work being performed, heart rate, and increases in heart rate

Multimode ergometer system

System overcomes previous ergometer design and calibration problems including inaccurate measurements, large weight, size, and input power requirements, poor heat dissipation, high flammability, and inaccurate calibration. Device consists of lightweight, accurately controlled ergometer, restraint system, and calibration system

Why impaired wellness may be inevitable in medicine, and why that may not be a bad thing

Context: A wellness crisis exists among physicians and medical trainees. High rates of burnout, depression, stress and other states of impaired wellness have driven a sense of urgency to create solutions, and the medical education community has mobilised impressively. However, we argue—and data suggest—that this rush to find solutions has outpaced our efforts to more fully understand the nature of impaired wellness in medicine. This, we believe, has led to the implementation of solutions informed by limited understanding of the problems we intend to solve. Methods: In this paper, we explore three contributors to this situation: (i) shaky definitions and conceptualisations of wellness, (ii) the predominance of deductive, quantitative research informing our understanding and current solutions, and (iii) the reliance on a ‘disease-focused’ approach to addressing impaired wellness in physicians and trainees. We discuss how these contributors have led to the current state of the science of wellness in medicine: one characterised by an expanding array of solutions built upon narrow conceptualisations of wellness and how it can be impaired. Discussion: Moving beyond the current state of the science on wellness in medicine will require three critical developments: (i) consistent use of clear definitions of wellness; (ii) expanding our methodologies to include those utilising direct interaction with participants; and (iii) moving beyond solutions informed by a disease-model approach. We propose a different way of thinking about wellness: one based on what we view as an inherent—and potentially unavoidable—risk of experiencing impairment during a career in medicine. We argue that efforts to extinguish and eliminate all states of impaired wellness may also eliminate opportunities to develop constructive coping mechanisms and future resilience, and that wellness may best be conceptualised as healthy and authentic engagement with the inevitable adversity of a career in medicine

An operating system for future aerospace vehicle computer systems

The requirements for future aerospace vehicle computer operating systems are examined in this paper. The computer architecture is assumed to be distributed with a local area network connecting the nodes. Each node is assumed to provide a specific functionality. The network provides for communication so that the overall tasks of the vehicle are accomplished. The O/S structure is based upon the concept of objects. The mechanisms for integrating node unique objects with node common objects in order to implement both the autonomy and the cooperation between nodes is developed. The requirements for time critical performance and reliability and recovery are discussed. Time critical performance impacts all parts of the distributed operating system; e.g., its structure, the functional design of its objects, the language structure, etc. Throughout the paper the tradeoffs - concurrency, language structure, object recovery, binding, file structure, communication protocol, programmer freedom, etc. - are considered to arrive at a feasible, maximum performance design. Reliability of the network system is considered. A parallel multipath bus structure is proposed for the control of delivery time for time critical messages. The architecture also supports immediate recovery for the time critical message system after a communication failure

Metacognitive Awareness and Mindset in Current and Future Principals

Metacognition is a key component in education, yet little is known about whether or not instructional leaders are metacognitively aware. Metacognition is described as thoughts about one\u27s knowledge and control over their own cognitive processes (Flavell, 1979). Kuhn (2000) indicated that metacognition develops from an early age, and asserted that the more explicit metacognitive thinking is, the more effective one would be able to engage in metacognitive thinking and control of their cognitive processes. Some examples of metacognitive strategies include planning, monitoring, and evaluating, and can be used by educators or students (Fathima, Sasikuman, & Roja, 2014). Metacognitive strategies should be selected based on tasks, contexts, and an awareness of situational activities (Bjork, Dunlosky, & Komell, 2013)

Getting grants

Attracting financial support is a critical element of success in science, but we have entered a time of cost constraint with little hope of relief coming soon. For principal investigators, developing a broad base of research support is a valuable strategy for attaining financial stability for the laboratory. New investigators working on problems related to virulence and just beginning to build their careers and laboratories must attain NIH funding. But they should also look beyond that agency to the other federal organizations, state and regional agencies, and non-profits that support research. This review will discuss the general principles of how to understand funders, their intentions, and their funding programs. An investigator who grasps what drives the funders will be better able to write fundable proposals

Observed Racial Socialization and Maternal Positive Emotions in African American Mother-Adolescent Dyadic Discussions about Racial Discrimination

This study examined patterns of: (1) racial socialization messages in dyadic discussions between 111 African American mothers and adolescents (M age = 15.50) and (2) mothers’ positive emotions displayed during the discussion. Mothers gave more total racial socialization responses to a hypothetical dilemma involving potential mistreatment by a White teacher than a dilemma involving rude treatment by a White salesperson. Mothers displayed more advocacy on behalf of their adolescents in response to the teacher dilemma than to the salesperson dilemma. Mothers displayed consistent emotional support of adolescents’ problem solving across both dilemmas but lower warmth in response to the salesperson dilemma. The role of adolescent gender in mothers’ observed racial socialization responses is also discussed
