    Ergometer

    Get PDF
    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

    Evaluation of the Effect of Consultant Characteristics on Telemedicine Diagnosis and Treatment

    This study examined teleconsultants' specialty, practice setting, type of employment, years and training in telemedicine to evaluate the effect of these characteristics on diagnoses and treatment. A postuse survey was conducted during 1998–2003 (n = 454 consultations) in the University of Arkansas for Medical Sciences' Rural Hospital, Telehealth Project. There were 61 consultants who conducted the teleconsultations. The teleconsultants established a diagnosis in 121 consultations and reported a change in diagnoses in 29 consultations. The consultants established a treatment plan in 219 consultations and reported a change in the treatment plan in 100 consultations. Dermatologists were significantly more likely to establish (P < .01) and change (P = .005) the diagnosis and to establish a treatment plan (P = .03), when compared to all other specialties. Teleconsultants who were self-employed were significantly more likely to change the treatment plan (P = .012). The findings suggest that teleconsultants' characteristics can affect diagnoses and treatment in telemedicine

    Resident connection to nature and attitudes towards tourism : findings from three different rural nature tourism destinations in Poland

    Get PDF
    Despite the growing literature arguing for the consideration of community perspectives in tourism destination governance, little is understood about how residents' connection to nature affects their perceptions of and responses to tourism. This is especially relevant for rural areas rich in nature as many of them have become refugees for urban dwellers seeking recreation during the COVID-19 pandemic. This study combines the Nature's Contributions to People framework and Weber's Theory of Formal and Substantive Rationality to shed light on how rural residents of three nature-based tourism destinations connect with nature and how this connection to nature affects perceptions of empowerment from tourism and ultimately support for tourism. Results provide credence to the importance of including measures of residents' connections to nature when examining attitudes towards tourism in nature areas with connections to nature having significant and positive influences on psychological empowerment and social empowerment at all three destinations and direct and positive effects on support for tourism across two of the three destinations. Furthermore, results suggest that understanding the role nature connection plays in how residents perceive changes within their community can help manage locally emerging conflicts within rural tourism-dependent communities

    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
