In this study, we first build two empirical cross-correlationmatrices in the US stockmarket by two different methods, namely the Pearson’s correlation coefficient and the detrended cross-correlation coefficient (DCCA coefficient). Then, combining the twomatriceswith the method of random matrix theory (RMT), we mainly investigate the statistical properties of cross-correlations in the US stock m...

In order to undertake controlled investigations into perceptual effects that relate to the interaural cross-correlation coefficient, experiment stimuli that meet a tight set of criteria are required. The requirements of each stimulus are that it is narrow band, normally has a constant cross-correlation coefficient over time, and can be altered to cover the full range of values of cross-correlat...

Using real time student response systems (clickers) in Management Information Systems classes (as well as in other disciplines) has previously been shown to lead to better student engagement and better student performance. This paper considers how the students’ overall performance in the class correlates with the students’ performance on various assessment tools used in the class. For medium si...

Background Chronic rhinosinusitis (CRS) is one of common health conditions that affects patients' health-related quality of life. Our purpose is to assess the reliability and validity of Thai-version of Sino-Nasal Outcome Test 22 in chronic rhinosinusitis. Methods Permission for translation of SNOT-22 from English language to Thai language was obtained from the developer. The translation proc...
