To reduce congestion and air pollution, 20% driving restriction, a license plate-based traffic control measure, has been implemented in Beijing since October 2008. While the long-term impacts of this policy remain controversial, it is important to understand how and why the policy effects of driving restrictions change over time. In this paper, the shortand long-run effects of the 20% driving r...

Critical flicker fusion thresholds (CFFT) describe when quick amplitude modulations of a light source become undetectable as the frequency of the modulation increases. The threshold at which CFF occurs has been shown to remain constant under repeated testing. Additionally, CFF thresholds are correlated with various measures of intelligence, and have been regarded by clinicians as a general meas...

OBJECTIVE This study evaluates whether patients with severe sensory deficits in the hypopharynx are at increased risk for aspiration and determines the relationship between pharyngeal muscular weakness and hypopharyngeal sensory deficits. STUDY DESIGN AND SETTING Forty patients with dysphagia who underwent flexible endoscopic evaluation of swallowing with sensory testing were prospectively di...

The stimulation of the human sensory receptors by compounds present in virgin olive oils (VOOs) gives rise to the sensory attributes that describe its particular aroma. The sensor panel evaluation and the molecules responsible for sensory perceptions of virgin olive oil quality are elucidated. The methodology for the evaluation of the sensory characteristics of VOOs is reported, and typical fla...

This issue of the American}ournal of Occupational Therapy commemorates the work of A_ Jean Ayres, an occupational therapist and neuropsychologist who, as a consummate clinician, developed a theory of sensory integration, created standardized tests and other measures co evaluate sensory integration, and designed a treatment approach to remediate sensory incegrative dysfunction. Therapists throug...
