Accurate assessment of the brake torque on a rope-braked cycle ergometer

Sports Engineering - A Monark cycle ergometer is a device globally used in physiological studies to measure the work and energy levels of exercising humans. In this paper a rope-braked cycle...     

Expectancies as mediators in the differential-reward conditional discrimination performance of pigeons

In a series of within-subject experiments employing a two-choice delayed conditional discrimination task, pigeons chose correctly more often when kind of correct choice and kind of reinforcer were perfectly correlated than when uncorrelated. Correct choice behavior fell to chance levels when the correlation was reversed or when it was removed by using only one kind of reinforcer. Implications for mediation theories are discussed, with the conclusion being that, although the possibility that instrumental mediators are present in this situation cannot be dismissed, the overall pattern of results indicates that classical mediators are of principal importance in this type of task.     

Ratings by Counselors Without Teaching Experience And Their Principals Regarding Performance of Guidance Functions

This study compared principal and self ratings of performance of guidance functions for practicing counselors who did not have teaching experience. The sample consisted of 43 counselors and their principals from throughout the United States. The ratings indicate better-than-average initial counselor acceptance by administrators, teachers, students, and parents with the degree of acceptance being greater after they had counseled for a while. Principal and self ratings differed significantly on initial acceptance by students and present acceptance by other counselors. Ratings of acceptance by both school psychologists and social workers were below average. There was no significant difference in counselor and principal ratings of counselor understanding of various school procedures and policies or of their ability to perform basic guidance activities. A majority of the principals who had worked with the counselors with non-teaching backgrounds indicated they would recommend the hiring of such a person to their school board.     

Systematically inflected versus grapheme modified signing: An educational viewpoint

Inflections may be interpolated into signed sequences by adding fingerspelled English inflectional morphemes to signs and fingerspelling irregular forms in which the bound morpheme is changed (grapheme modified signing), or by introducing signs corresponding to the major English inflections which can be associated with existing or newly coined bound morphemes (systematically inflected signing). The SIS method may be much less complex than GMS if it does not attempt to provide cues to the spoken form, or it may be painstakingly matched to the production features of speech at the risk of increasing its complexity. Further knowledge on the extent to which inflected signs may be systematized and on the extent to which integration of SIS and GMS may be desirable is contingent upon research into the production, decoding and ease of learning parameters of gestural communication.     

Expert Workshop Assesses the Significance of Birth Location on Maternal and Infant Outcomes

On March 6–7, 2013, some of the greatest minds in research and the provision of maternity care came together for a workshop on “Research Issues in the Assessment of Birth Settings,” hosted by the prestigious Institute of Medicine (IOM) and sponsored by the W.K. Kellogg Foundation.
