Introduction: Most hospitals routinely examine microscopically all tonsillar and adenoid specimens from healthy pediatric patients complaining of recurrent infections or obstructive sleep apnea. Concern over missing the rare, unsuspected and significant diagnosis propagates this practice. Clinical examination for asymmetry could obviate the need for routine microscopic examination of tonsil and...
هدف تحقیق، بررسی تاثیر عدم اطمینان محیطی بر رابطهی بین مدیریت سود و عدم تقارن اطلاعاتی است. مدیریت سود با استفاده از اقلام تعهدی اختیاری حاصل از تخمین مدل معرفی شده توسط توسط کوتاری، لئون و وازلی (2005) سنجیده شـده است. عدم اطمینان محیطی از طریق ضریب تغییرات میزان فروش شش سال اخیر برای هر شرکت محاسبه شد. دادههای تحقیق برای ۱۴۲ شرکت نمونهی آماری از میان شرکت های پذیرفته شده در بورس اوراق بهاد...
هدف از این تحقیق بررسی ارتباط بین عوامل فرهنگی و عدم تقارن اطلاعاتی در گزارشگری مالی شرکتهای پذیرفته شده در بورس اوراق بهادار تهران میباشد. در این تحقیق برای اندازهگیری فرهنگ از پرسشنامه استاندارد هوفستد و برای بررسی عدم تقارن اطلاعاتی از شاخص شکاف قیمتی سهام استفاده شده است. در این تحقیق حدود 50 شرکت از شرکتهای پذیرفته شده در بورس اوراق بهادار تهران مورد بررسی قرار گرفته است و از متغیرهای...
In this study we investigated the association between morphological asymmetry and patterns of cognitive ability in dementia of Alzheimer's type (DAT). Digitized CT scans were used to estimate volumetric parameters of the brain. The volume of the cranium, brain parenchyma, the subarachnoid space, and lateral ventricles was computed. The volume of the subarachnoid space was used as an index of co...
Three major types of bilateral asymmetry (fluctuating asymmetry, directional asymmetry, and antisymmetry) have long been recognized in the literature. Little, however, is known about transitions between asymmetry types, especially in natural populations. It is often assumed that directional asymmetry and antisymmetry have a larger genetic basis than fluctuating asymmetry. This leads many scient...
Morphological asymmetry is widely used to measure developmental instability and higher levels of asymmetry often correlate with decreased mating success, increased inbreeding, increased stress and decreased habitat quality. We studied asymmetry and relationships between asymmetry and host identity in two flea species, host generalist Xenopsylla ramesis and host specialist Parapulex chephrenis, ...
OBJECTIVE To investigate the perception of facial asymmetry in young adults to identify the amounts of chin asymmetry that can be regarded as normal and may benefit from correction. MATERIALS AND METHODS Three-dimensional (3D) images of 56 individuals of mixed ethnicity were obtained and used to produce average 3D images of male and female faces. Distortion was then applied to these average f...
Gait asymmetry analyses are beneficial from clinical, coaching and technology perspectives. Quantifying overall athlete asymmetry would be useful in allowing comparisons between participants, or between asymmetry and other factors, such as sprint running performance. The aim of this study was to develop composite kinematic and kinetic asymmetry scores to quantify athlete asymmetry during maxima...
