In the present study we examined the effect of positional noise on spatial resolution in younger and older observers. We used a yes/no discrimination task in which observers indicated whether the size of two gaps in a Landolt-C-like contour was the same or not. The proportion of trials observers perceived one gap larger was measured when gaps-position was fixed (low positional noise) and random...

The information society has become increasingly dependant on programs that are subjected to frequent evolutive, basic and logical changes for a variety of reasons whereas the visual design of the program/program interface mostly remains the same or gets slightly modified. The development of technology has become to such an extent a commonplace that the use of redesigned programs implies icons t...

In an article, " Antimicrobial activity of antituberculosis agents against anaerobic bacteria, " in the May 1979 issue of Chest (75:569-570) Thadepalli et al have left the reader in confusion by opposing statements in the body of the paper and in the summary. In the body of the paper: " Rifampin therefore appears to be an ideal antibiotic for the treatment of anaerobic pulmonary infections asso...

In most cultures, “yes” is indicate by a vertical head movement (nod), while “no” is indicated by a left-right movement (shake). In this paper, we show that basic symmetries can explain this cultural phenomenon. 1 Formulation of the Problem In most cultures, “yes” is indicated by a vertical head movement (nod), while “no” is indicated by a left-right movement (shake); see, e.g., [1]. There are ...

Late-onset (adolescent) idiopathic scoliosis is the commonest spinal deformity seen in our clinics. Like many orthopaedic deformities the degree of the condition determines its importance. When schoolchildren are examined many small inconsequential curves may be seen since it is difficult to keep a straight spine in the face of threedimensional growth for 20 years. The condition becomes progres...
