Presents an obituary for Nicholas Hobbs. Just at the end of his stellar career of public service through psychology, Nick Hobbs received very appropriate honors showing that psychologists and many others knew what a precious national resource his life had been. Only days before his death from cancer on January 23, 1983, he participated in the dedication of the Nicholas Hobbs Laboratory of Human Development of the Peabody College for Teachers of Vanderbilt University, part of the Kennedy Center for Research on Education and Human Development that he founded and directed at its beginning. Two years earlier, he had received two parallel American Psychological Association (APA) awards--one for Distinguished Contributions to Psychology in the Public Interest and another for Distinguished Professional Contributions "utilizing psychological knowledge in the public interest and social policy." As the citations and testimonials on these occasions variously noted, Nick gave creative, responsible, and effective service to the institutions that he helped administer, to the Southern region from which he sprang, to the APA, and to the profession of psychology, but above all to the nation's children and youth, especially those who grew up with disadvantage and difficulty.

A complete and effective rehabilitation program begins with a thorough subjective and objective evaluation of the problem and injury presented. Biomechanical changes, whether they are anatomically induced or as a result of a form of compensation, must be identified and properly addressed. During the initial phase of rehabilitation, the issues of pain and swelling often must be resolved before full range of motion and return to normal strength can be achieved successfully during the more advanced stages. It is important to incorporate the entire lower quadrant in exercises that are designed to improve proprioception and function, using both in open and closed kinetic chain exercises. Finally, the demands to which the patient is returning to must be recognized to successfully complete the recovery phase. 相似文献

A new strategy for routing handover signalling in microcellular environments is proposed. Simulation results show that time delay for handover packets travelling across the fixed network could be reduced by diverting the signalling through the air interface between the serving and the candidate base station (BS) 相似文献

Although landmarks are an integral part of navigation, they have rarely been used explicitly within electronic pedestrian navigation aids. We describe a two-part study into the use of landmarks in such aids, using a set of field experiments. The first part investigated whether such devices can be effective for older adults (over 60 years old), who might particularly benefit from them due to declines in sensory, cognitive and motor abilities. The second part compared the effectiveness of different methods of presenting landmark information. We show that a pedestrian navigation aid based around landmarks is particularly useful for older people and demonstrate that text, speech and photographs are all effective ways of presenting landmark information, although speech on its own has some drawbacks. We found that different people prefer information to be presented in different modalities, indicating a need for personalisation, although multi-modality may also help to address this issue. 相似文献

We derive here a generalization to nonlinear problems of the “free steering theorem” of Ostrowski on sufficient conditions for convergence of linear SOR with varying relaxation parameters. 相似文献

Trained 14 Silver King pigeons in a symbolic matching-to-sample task in which food (access to grain) and no-food (blackout) samples were used. Responding to red test stimuli was reinforced on food sample trials, and responding to green test stimuli was reinforced on no-food sample trials. Samples of food and no food were rendered "expected" or "surprising" during subsequent testing by preceding samples with a previously established signal for either food (CS+) or no food (CS–). CS+ preceded food samples and CS– preceded no-food samples on surprising trials. Findings suggest that enhanced retention on surprising trials was apparent from the outset of testing to the extent that (a) surprising and expected trials were not markedly dissimilar to the trials of training, and (b) control over test responding by the CSs presented on expected and surprising trials was minimized. Results are discussed with regard to generalization decrement and directed remembering. It is concluded that surprising samples receive enhanced postperceptual processing and that the mechanism involved is that of retrieval-generated priming of short-term memory.

This paper introduces the development of a multimodal data visualisation system and its evaluations. This system is designed to improve blind and visually impaired peoples access to graphs and tables. Force feedback, synthesized speech and non-speech audio are utilised to present graphical data to blind people. Through the combination of haptic and audio representations, users can explore virtual graphs rendered by a computer. Various types of graphs and tables have been implemented, and a three-stage evaluation has been conducted. The experimental results have proven the usability of the system and the benefits of the multimodal approach. The paper presents the details of the development and experimental findings, as well as the changes of role of haptics in the evaluation. 相似文献

We present here a computational process which establishes the convergence of nonlinear successive-overrelaxation in finding the minimum of a strictly convex functional. The algorithm is designed in such a manner that the SOR parameter is computed appropriately to guarantee convergence. Numerical examples are presented. 相似文献

Just as Sigmund Koch was a good scientist without succumbing to scientism, he was a good humanist without succumbing to the popular distortions trading on the name of humanism. When humanistic psychology was seduced by the touchy–feely encounter group movement, Koch derided its technology of authenticity as shamelessly meretricious. Later, when postmodern humanists of deconstruction and textual analysis began to be heard in psychology, Koch wryly expressed his preference for the old-fashioned kind of humanism. Koch's interests and his conception of the domain of psychology thus transcended scientific and humanistic labels and boundaries. To be good science, human psychological studies have to start with and be guided by openness to all aspects of being human. No less in the present and future than during his lifetime, the implications of Koch's vision of psychological inquiry warrant discerning and disciplined attention.
