Analysis of affective instability on ecological momentary assessments data: successive difference, variance decomposition, and mean comparison via multilevel modeling
Temporal instability of affect is a defining characteristic of some psychological disorders such as Borderline Personality Disorder and mood cycling disorders. Use of Ecological Momentary Assessments (EMA) enables researchers to directly assess such frequent and extreme fluctuations over time. Two …

'Ex-ante' asset allocation strategies for global index portfolios
… in empirically assessing the extent of inter~temporal instability in the inputs to theglobal portfolio optimization problem and in developing appropriate multivariate estimation procedures that aim to assist investors in achieving superior out of sample portfolio performance. The empirical …

Tactical Allocation Through the Lens of Correlational Time-Variance, Determinants, and Regimes
… (WC) methodology, where our findings reveal temporal instability. Through a multi-method statistical approach, we present robust and persuasive evidence of macroeconomic factors as determinants of temporal change. Leveraging time-varying Granger causality, we unearth elusive yet significant …

A Mathematical Analysis of Digestive Processes in a Model Stomach
… mixing of two layers of creeping fluid through temporal instability of the perturbed fluid interface. Some attention is also paid to a more general study of the surrounding flow field. Linear, two-fluid flow next to a prescribed, sinusoidally moving wall is found to be stable in all cases. …

Studies of generalized worry in college students
… the threat. Therefore, better-understanding the temporal dynamics of information processing as a function of worry severity may lead to the identification of objective markers of pathological worry that can then be used as targets for anxiety treatment. The present studies were conducted to …

Theoretical And Experimental Investigation Of The Cascading Nature Of Pressure-Swirl Atomization
… remains constant. A new approach to analyze the temporally unstable waves was developed and compared with the measured maximum wavelengths. The new approach incorporates the attenuation of a film thickness, as the radius of a conical film expands, with the classical dispersion relationship for an …
