The roles of interaural time difference (ITD) and interaural level difference (ILD) were studied in free-field source localization experiments for sine tones of low frequency (250-750 Hz). Experiments combined real-source trials with virtual trials created through transaural synthesis based on real-time ear canal measurements. Experiments showed the following: (1) The naturally occurring ILD is...

OBJECTIVE Many musculoskeletal fellowships are nonaccredited, leading to heterogeneity of educational experiences. There is no governing body for these nonaccredited fellowships, leaving program content and rules to the program directors' discretion. In addition, imaging fellowships in general currently face many external pressures that challenge their capacity to provide a high-quality educati...

a simple and efficient method for the chemoselective 1,1-diacetate protection of aromatic aldehydes with acetic anhydride by using ni2+ supported on hydroxyapatite-core-shell magnetic γ-fe2o3 nanoparticles (γ-fe2o3@hap-ni2+) under solvent free conditions. this method has several advantages, including high yield, short reaction time, simple work-up and recyclable property of the catalyst. the ca...

this descriptive cross sectional census study identified the perceptions of extension and outreach employees of iowa state university in the united states about job autonomy and control after two years of a major restructuring. employees perceived autonomy and control over expressing views and ideas about their work and spending time on the job but perceived little influence over budget allocat...

in this paper, the deformation of a thick-walled circular cylindrical shell of incompressible isotropic elastic material is considered. the shell, which is made of three-term strain energy function is subjected to the combined external and axial loading pressure. in order to obtain the relevant eigenvalues, which is the main objective of the work, the incremental equilibrium equations are so...

This study examined a model of meaningful work among a diverse sample of working adults. From the perspectives of Self-Determination Theory and the Psychology of Working Framework, we tested a structural model with social class and work volition predicting SDT motivation variables, which in turn predicted meaningful work. Partially supporting hypotheses, work volition was positively related to ...
