Fluctuating asymmetry, random departure from perfect symmetry in bilateral traits, has been proposed as an indirect indicator of individual quality. Sexually selected traits, such as deer antlers, are hypothesized to demonstrate decreasing level of fluctuating asymmetry with increasing trait size and decreasing level of fluctuating asymmetry with increasing age. These hypotheses have been previ...
In the literature, numerous statistical analyses are used to quantify asymmetry in gait. This study tested the effect size (ES) statistic for quantifying asymmetry in nondisabled and pathological populations. The plantar pressure peaks on eight footprint locations of 27 nondisabled subjects and 18 patients with hemiparesis were bilaterally compared. Asymmetry quantifications were performed with...
نوسان پذیری بازده سهام که به تغییرات در قیمت سهام گفته میشود تحت تأثیر عوامل متعددی در بازار است. از عوامل اثر گذار بر نوسان پذیری بازده سهام، عدم تقارن اطلاعاتی است (آینفوس، 2015) عدم تقارن اطلاعاتی نیز میتواند تحت تأثیر کیفیت افشای اطلاعات باشد (هرمالین و ویس بچ، 2007). بر این اساس تبیین ارتباط بین این متغیرها و چگونگی ارتباط بین آنها در بازار سرمایه ایران نیر میتواند قابل توجه باشد. ب...
BACKGROUND While asymmetry in the fusiform gyrus (FFG) has been reported in functional and structural studies in typically developing controls (TDC), few studies have examined FFG asymmetry in autism spectrum disorder (ASD) subjects and those studies are limited by small sample sizes, and confounded by cognitive ability or handedness. No previous work has examined FFG surface area or cortical t...
Hippocampi are asymmetrical in children and adults, where the right hippocampus is larger. To date, no literature has confirmed that hippocampal asymmetry is evident at birth. Furthermore, gender differences have been observed in normal hippocampal asymmetry, but this has not been examined in neonates. Stress, injury, and lower IQ have been associated with alterations to hippocampal asymmetry. ...
Developmental stability, as measured by fluctuating asymmetry, has been purported to be an indicator of individual quality, and low asymmetry can be selected for by sexual selection processes. However, low asymmetry can also arise due to biomechanical constraints operating on trait design, as it is predicted that asymmetry will decrease mechanical efficiency. Specifically, it has been predicted...
