The Examination of Organizational Respect in Relation to Organizational Culture
This paper is an in-depth examination of the connection between organizational respect and the strong roots of organizational culture. Throughout this thesis, we will examine the importance of management recognizing and implementing respect, how respect affects behaviors and characteristics of employees, and ways in which employees tend to feel the most respected. Additionally, we will closely examine the importance of establishing feelings of support, caring, and collaboration within an organization in efforts to create an environment filled with respect. Another concept that will be examined is the idea of person-culture fit, and how the alignment of values between employees and the overall organization can ultimately make or break its success. These concepts are important, because they collaboratively determine whether or not the organization will be able to sustain itself going forward. By the end of this paper, you will have a better understanding of the importance of organizational respect and how it contributes to organizational culture, as well as how organizational respect influences organizational culture and influences employee fit in organizations
A fibre optic, four channel comparative photometer
Development of a four channel comparative photometer is described. Tests have shown that it is stable from night to night and is capable of working in very poor sky conditions. Even when the sky conditions are so poor that stars are barely visible, light curves can still be obtained with an r.m.s. value of 0.0016 mag., provided that integration times that are long compared with the transparancy changes are possible
Real-time flutter analysis
The important algorithm issues necessary to achieve a real time flutter monitoring system; namely, the guidelines for choosing appropriate model forms, reduction of the parameter convergence transient, handling multiple modes, the effect of over parameterization, and estimate accuracy predictions, both online and for experiment design are addressed. An approach for efficiently computing continuous-time flutter parameter Cramer-Rao estimate error bounds were developed. This enables a convincing comparison of theoretical and simulation results, as well as offline studies in preparation for a flight test. Theoretical predictions, simulation and flight test results from the NASA Drones for Aerodynamic and Structural Test (DAST) Program are compared
Constructing transportable behavioural models for nonlinear electronic devices
We use radial basis functions to model the input--output response of an
electronic device. A new methodology for producing models that accuratly
describe the response of the device over a wide range of operating points is
introduced. A key to the success of the method is the ability to find a
polynomial relationship between the model parameters and the operating points
of the device.Comment: The file is in Revtex, it is 7 pages (two collumn format) with 13

Inference of epidemiological parameters from household stratified data
We consider a continuous-time Markov chain model of SIR disease dynamics with
two levels of mixing. For this so-called stochastic households model, we
provide two methods for inferring the model parameters---governing
within-household transmission, recovery, and between-household
transmission---from data of the day upon which each individual became
infectious and the household in which each infection occurred, as would be
available from first few hundred studies. Each method is a form of Bayesian
Markov Chain Monte Carlo that allows us to calculate a joint posterior
distribution for all parameters and hence the household reproduction number and
the early growth rate of the epidemic. The first method performs exact Bayesian
inference using a standard data-augmentation approach; the second performs
approximate Bayesian inference based on a likelihood approximation derived from
branching processes. These methods are compared for computational efficiency
and posteriors from each are compared. The branching process is shown to be an
excellent approximation and remains computationally efficient as the amount of
data is increased
Flight test trajectory control analysis
Recent extensions to optimal control theory applied to meaningful linear models with sufficiently flexible software tools provide powerful techniques for designing flight test trajectory controllers (FTTCs). This report describes the principal steps for systematic development of flight trajectory controllers, which can be summarized as planning, modeling, designing, and validating a trajectory controller. The techniques have been kept as general as possible and should apply to a wide range of problems where quantities must be computed and displayed to a pilot to improve pilot effectiveness and to reduce workload and fatigue. To illustrate the approach, a detailed trajectory guidance law is developed and demonstrated for the F-15 aircraft flying the zoom-and-pushover maneuver
The feeding behaviour and Plasmodium infection of Anopheles mosquitoes in southern Ethiopia in relation to use of insecticide-treated livestock for malaria control.
Anopheles arabiensis and An. quadriannulatus species B mosquitoes were collected at sites of human and livestock housing and analysed for blood feeding patterns and infection with malaria sporozoites. A low percentage of human blood meals at some sites suggested that zooprophylaxis could be effective in reducing challenge from Plasmodium falciparum
