Objective and subjective measures for sleep disorders

Objective and subjective sleep disorders in automated peritoneal dialysis

BACKGROUND Automated peritoneal dialysis (APD) is one of the fastest growing dialysis modalities. It is unknown whether sleep and mood are disturbed while performing repeated overnight exchanges. OBJECTIVES In this report, we aim to describe and compare the prevalence of sleep-disordered breathing (SDB), periodic limb movements (PLMS), poor sleep quality (SQ), and depression among APD patient...

Comparing objective and subjective error measures for color constancy

We compare an objective and a subjective performance measure for color constancy algorithms. Eight hyper-spectral images were rendered under a neutral reference illuminant and four chromatic illuminants (Red, Green, Yellow, Blue). The scenes rendered under the chromatic illuminants were color corrected by 5 color constancy algorithms that are based on zero-, firstand second-order image statisti...

Website Complexity: Objective versus Subjective Measures

Site complexity has been defined both as a single construct and as multi-dimension construct and operationalized in terms of objective measures or user perceptions. In this research, we distinguish between objective and subjective (perceived) site complexity and examine the relationship between the two. Objective site complexity is measured by how varied a website is; subjective site complexity...

Subjective Sleepiness and Sleep Quality in Adolescents are Related to Objective and Subjective Measures of School Performance

This study investigated the relation between sleep and school performance in a large sample of 561 adolescents aged 11-18 years. Three subjective measures of sleep were used: sleepiness, sleep quality, and sleep duration. They were compared to three measures of school performance: objective school grades, self-reported school performance, and parent-reported school performance. Sleepiness - "I ...
