A Qualitative and Quantitative Assessment of Readiness for Organizational Change Literature
The purpose of this thesis is to take a step in integrating the change literature and accumulate the empirical results using meta-analytic techniques. First, a literature review of existing research on organizational change was conducted. Second, existing models of organizational change were integrated to create a theoretical structure. Third, a meta-analysis was performed to derive the corrected correlation values for each relationship in that structure. Finally, the readiness for change literature was qualitatively assessed. In addition, a quantitative review was done by accumulating the results across 25 studies in an effort to provide a current quantitative assessment of change management will update Robertson et al\u27s (1993) findings to produce a representative and generalizable guide to organizational change readiness
Technocratic Teamwork: Mitigating Polarization and Cultural Marginalization in an Engineering Firm
Many corporations attempt to establish a unified corporate culture as a way of orienting employees toward corporate goals and objectives. However, a technocratic organizational structure has been found to exist in many high-tech corporations, which divides employees into an expert and non-expert sector based on differences in credentials and technical expertise. Because of this division, employees working within these two sectors experience differences in corporate rewards, worker autonomy, and creative freedoms. These factors have been found to lead to a polarized, divided, and discontented workforce. To understand how a technocratic structure influences and affects a dominant corporate culture and organizational efficacy, we conducted a qualitative study of a high-tech corporation named SYS, located in the Southwestern United States. We chose three occupational groups to participate in this study: engineers, technicians, and administrative assistants. The intent of this study was to determine how employees from these three occupational groups, who differ according to gender, education, and technical expertise, see and interpret the dominant culture within a technocratic organizational structure. The data from this study suggest that a strong and vibrant team-based organizational structure appears to mitigate the polarization that has been found to exist within many technocracies. The results obtained from this case study also suggest that despite differences between these occupational groups, a teaming environment appears to bridge significant differences between these occupational groups and to create a cohesive workforce
Cardiac mass in glucocorticoid-hypertensive rats with and without circulating adrenaline.
There is evidence that catecholamines may promote the development of cardiac hypertrophy in hypertension. To test the hypothesis that adrenaline directly determines left ventricular mass, normotensive Wistar rats were made adrenaline-deficient by adrenalectomy and hypertensive by administration of glucocorticoid. Blood pressure, heart rate, and body weight of the adrenalectomised group were not significantly different from a glucocorticoid treated control group with intact adrenals. Heart weight was significantly lower in the adrenalectomised rats, but this difference disappeared when heart weight was adjusted for body weight. It appears therefore that the presence or absence of adrenaline does not significantly affect cardiac mass in the presence of hypertension in this animal model
Conceptual Model-Based Reasoning for Knowledge-Based Software Project Management
This paper presents a conceptual model for software project management and the power derived from using a conceptual model-based reasoning approach in building intelligent decision-support systems. The Software Project Manager (SPM) has been prototyped in Inference Corporation\u27s Automated Reasoning Tool (ART) on Symbolics artificial intelligence (Al) workstations. This prototype conceptual model is an outgrowth of research con- ducted under the Knowledge-Based Software Project Management project at Lockheed Software Technology Center in Austin, Texas. In this paper, we present an overview of the management model underlying SPM and define the essential concepts and relationships needed to model the project management domain. We then describe the knowledge representation strategy used to implement this conceptual model. Finally, we illustrate the power of using conceptual model-based reasoning in building intelligent decision-support systems for the project management domain
Debris and micrometeorite impact measurements in the laboratory
A method was developed to simulate space debris in the laboratory. This method, which is an outgrowth of research in inertial confinement fusion (ICF), uses laser ablation to accelerate material. Using this method, single 60 micron aluminum spheres were accelerated to 15 km/sec and larger 500 micron aluminum spheres were accelerated to 2 km/sec. Also, many small (less than 10 micron diameter) irregularly shaped particles were accelerated to speeds of 100 km/sec

Hunting for the New Symmetries in Calabi-Yau Jungles
It was proposed that the Calabi-Yau geometry can be intrinsically connected
with some new symmetries, some new algebras. In order to do this it has been
analyzed the graphs constructed from K3-fibre CY_d (d \geq 3) reflexive
polyhedra. The graphs can be naturally get in the frames of Universal
Calabi-Yau algebra (UCYA) and may be decode by universal way with changing of
some restrictions on the generalized Cartan matrices associated with the Dynkin
diagrams that characterize affine Kac-Moody algebras. We propose that these new
Berger graphs can be directly connected with the generalizations of Lie and
Kac-Moody algebras.Comment: 29 pages, 15 figure
Neutron-Capture Elements in the Early Galaxy: Insights from a Large Sample of Metal-Poor Giants
New abundances for neutron-capture (n-capture) elements in a large sample of
metal-poor giants from the Bond survey are presented. The spectra were acquired
with the KPNO 4-m echelle and coude feed spectrographs, and have been analyzed
using LTE fine-analysis techniques with both line analysis and spectral
synthesis. Abundances of eight n-capture elements (Sr, Y, Zr, Ba, La, Nd, Eu,
Dy) in 43 stars have been derived from blue (lambda = 4070--4710, R~20,000, S/N
ratio~100-200) echelle spectra and red (lambda = 6100--6180, R~22,000, S/N
ratio~100-200) coude spectra, and the abundance of Ba only has been derived
from the red spectra for an additional 27 stars. Overall, the abundances show
clear evidence for a large star-to-star dispersion in the heavy element-to-iron
ratios. The new data also confirm that at metallicities [Fe/H] <~ --2.4, the
abundance pattern of the heavy (Z >= 56) n-capture elements in most giants is
well-matched to a scaled Solar System r-process nucleosynthesis pattern. The
onset of the main r-process can be seen at [Fe/H] ~ --2.9. Contributions from
the s-process can first be seen in some stars with metallicities as low as
[Fe/H] ~ --2.75, and are present in most stars with metallicities [Fe/H] >
--2.3. The lighter n-capture elements (Sr-Y-Zr) are enhanced relative to the
heavier r-process element abundances. Their production cannot be attributed
solely to any combination of the Solar System r- and main s-processes, but
requires a mixture of material from the r-process and from an additional
n-capture process which can operate at early Galactic time.Comment: Text + 5 Tables and 11 Figures: Submitted to the Astrophysical

A Formalization of the Theorem of Existence of First-Order Most General Unifiers
This work presents a formalization of the theorem of existence of most
general unifiers in first-order signatures in the higher-order proof assistant
PVS. The distinguishing feature of this formalization is that it remains close
to the textbook proofs that are based on proving the correctness of the
well-known Robinson's first-order unification algorithm. The formalization was
applied inside a PVS development for term rewriting systems that provides a
complete formalization of the Knuth-Bendix Critical Pair theorem, among other
relevant theorems of the theory of rewriting. In addition, the formalization
methodology has been proved of practical use in order to verify the correctness
of unification algorithms in the style of the original Robinson's unification
algorithm.Comment: In Proceedings LSFA 2011, arXiv:1203.542
