Computational Intelligence Techniques for OES Data Analysis
… physics involved. Optical Emission Spectroscopy (OES) measurements can be collected non-intrusively during wafer processing and are being used more and more in semiconductor manufacturing as they provide real time plasma chemical information. However, the use of OES measurements is challenging due …

The Occupational Engagement Scale for Employed Adults - Revised (OES-EA-R): Further validation and correlations with personality and Holland code type
… the Job Satisfaction Blank (Hoppock, 1935). The OES-EA-R was also compared and contrasted with scales from the NEO-FFI (Costa & McCrae, 1992), an abbreviated Big Five personality measure. Additionally, the OES-EA-R was examined for any significant differences among occupations falling within …

Openness to Experience Rather than Overexcitabilities
… gifted individuals, called overexcitabilities (OEs). Most studies present OEs outside of the context of the original theory (Mendaglio, 2012). Atheoretically conceptualized, OEs seem to define the personality trait of openness to experience as each OE can be matched with a specific facet of …
