Investing in newsrooms during the layoff era
(University of Missouri--Columbia, 2020)
that reverse dwindling circulation numbers remain a worthy pursuit. This study examines medium-sized newspapers from around the country during what's described as the "layoff era" -- the period of time following the economic recession that began in 2007...
Multilevel models for intensive longitudinal data with heterogeneous error structure : covariance transformation and variance function models
(University of Missouri--Columbia, 2008)
Recent developments in data collection methods in the behavioral and social sciences, such as Ecological Momentary Assessment (EMA) enables researchers to gather intensive longitudinal data (ILD) and to examine more detailed ...
Classification of rock glaciers in southern Colorado based on ice content using radar interferometry and thermal remote sensing
(University of Missouri--Columbia, 2020)
Remote sensing provides a means of assessing potential water resources stored in alpine ground ice; this study focuses on rock glaciers, in particular. A rock glacier is a landform composed of block of loose debris (talus) ...
Cognitive load and time based forgetting
(University of Missouri--Columbia, 2009)
Recently, various researchers have claimed that time does not play a direct role in shortterm forgetting. Instead, they claim that time is only related to forgetting because it is correlated with other factors that cause ...
Is maturing out of problematic alcohol involvement related to personality change?
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Problematic alcohol involvement typically peaks in the early 20s and declines with age. This "maturing out" of alcohol involvement is usually attributed to individuals' attaining...
Effect of plagioclase crystallization on liquid and magma viscosity in the Anorthite-diopside-dorsterite-quartz system
(University of Missouri--Columbia, 2006)
SiO2 (CMAS) glasses were synthesized as analogs for dacitic and basaltic lavas. Liquid viscosities were measured between 101 and 1013 Pa s, over the temperature range of approximately 1600 to 700⁰C, using concentric cylinder ...
Influences of anxiety on golf performance: a field test of catastrophe theory
(University of Missouri--Columbia, 2005)
The purpose of this study was to test the basic tenets of Fazey and Hardy's (1988) catastrophe model. Specifically, the purpose was to examine the interaction effects of cognitive anxiety (worry) and physiological arousal (activation) on golf...
Director ties, board experience, and firm strategic outcomes : board experience effects on post-acquisition performance
(University of Missouri--Columbia, 2006)
of the entire assets of target firms. Results generally do not support the notion that acquiring firms benefit through positive post-acquisition performance from the past experience of their outside directors. However, significant results with respect to board...
How sweet it is to be loved by you : toward an understanding of why close relationships buffer existential fear
