The Relation Between Information-Processing Variables and Test-Retest Stability for Questionnaire Items

Recently developed cognitive theories explain why some questionnaire items can be answered in a reliable and valid manner and others cannot. Those theories distinguish two components: (a) the interpretation or understanding of a question and (b) the role of memory. The present study investigates the ability of these two components to forecast the test-retest association coefficients of 207 pilot questionnaire items used in an international study of reading literacy in which 2 populations were involved: Grade 5 and Grade 2 of primary and secondary education, respectively. The analysis of the data showed that for both populations, both components forecast the relative sizes of the test-retest correlation coefficients. The results strongly suggest that if one wishes to use questionnaire items in research about relationships, then the items should be as unambiguous as possible. Moreover, the information needed to formulate an answer must be easily accessible in the respondent's memory.     

The effects of verbal scaffolding instruction on young children's private speech and problem-solving capabilities

This investigation examined the efficacy of a verbal scaffolding instructional program designed to teach young children how to use private speech while working on school tasks and problems. Two different contexts for solving problems were used; common school tasks and analogical reasoning problems. Thirty-four 5-year olds who attended public school kindergartens were assigned to either the comparison group or the treatment group. Comparison group subjects were presented with a series of 8 lessons which focused on a cognitive strategy to be used in the solutions of geometric analogy problems. Treatment group subjects were presented with a series of 8 lessons which employed cognitive self-instruction in a verbal scaffolding format. After initial instruction using self-verbalizations, treatment group subjects were shown how to apply the cognitive self-instruction to routine school tasks and geometric analogy problems. The data analysis revealed that there was an effect on the treatment group's use of 3 of the 4 levels of private speech. When the two groups were compared, the treatment group used significantly less task irrelevant private speech and significantly more task relevant private speech. There were no significant differences between the two groups on the post-assessment of geometric analogy reasoning. Additionally, when the two groups were compared there were positive effects of the instructional program on the treatment group's classroom behavior (near transfer) and locus of control scores (far transfer). The results of this study provide support for the use of cognitive self-instruction to improve young children's problem-solving private speech in the context of a public school classroom.Portions of this paper were presented at the 2nd Annual European Congress of Psychology, Budapest Hungary, July 1991 by the first author.This paper was presented at the 1993 annual meeting of the American Educational Research Association, Atlanta, GA.     

Continuing education and library services for physicians in office practice.

A program is described which incorporates library services into continuing medical education for physicians. The educational service is based on the actual needs of the physician rather than on his perceived needs. The needs assessment is accomplished by reviewing drug-prescribing habits. Current medical literature is then selected for the physician to coincide with his unique educational needs. The program is further designed to evaluate the change in the physician's drug-prescribing habits as a result of his study of the literature received.     

Functional phases and angular momentum characteristics of Tkatchev and Kovacs

Understanding the technical requirements and underlying biomechanics of complex release and re-grasp skills on high bar allows coaches and scientists to develop safe and effective training programmes. The aim of this study was to examine the differences in the functional phases between the Tkatchev and Kovacs skills and to explain how the angular momentum demands are addressed. Images of 18 gymnasts performing 10 Tkatchevs and 8 Kovacs at the Olympic Games were recorded (50 Hz), digitised and reconstructed (3D Direct Linear Transformation). Orientation of the functional phase action, defined by the rapid flexion to extension of the shoulders and extension to flexion of the hips as the performer passed through the lower vertical, along with shoulder and hip angular kinematics, angular momentum and key release parameters (body angle, mass centre velocity and angular momentum about the mass centre and bar) were compared between skills. Expected differences in the release parameters of angle, angular momentum and velocity were observed and the specific mechanical requirement of each skill were highlighted. Whilst there were no differences in joint kinematics, hip and shoulder functional phase were significantly earlier in the circle for the Tkatchev. These findings highlight the importance of the orientation of the functional phase in the preceding giant swing and provide coaches with further understanding of the critical timing in this key phase.     

Live-streaming: Time-lapse video evidence of novel streamer formation mechanism and varying viscosity

Time-lapse videos of growing biofilms were analyzed using a background subtraction method, which removed camouflaging effects from the heterogeneous field of view to reveal evidence of streamer formation from optically dense biofilm segments. In addition, quantitative measurements of biofilm velocity and optical density, combined with mathematical modeling, demonstrated that streamer formation occurred from mature, high-viscosity biofilms. We propose a streamer formation mechanism by sudden partial detachment, as opposed to continuous elongation as observed in other microfluidic studies. Additionally, streamer formation occurred in straight microchannels, as opposed to serpentine or pseudo-porous channels, as previously reported.
