Determination of aerosol content in the atmosphere

This investigation is designed to demonstrate the feasibility of determining the aerosol content in the atmosphere from contrast measurements of ground features, and from radiance measurements. Theoretical relationships between aerosol content and contrast reduction and radiance have been derived for ideal model atmospheres. The preliminary data analysis of the MSS transparencies has shown promising results for the contrast-aerosol content relationship in the Salton Sea/desert region

The educational scorecard: The Start of our Journey

Against a backdrop of public sector cuts, increasing university fees and high youth unemployment, we are facing challenges in Higher Education to demonstrate the value of our courses. Assessing the value of learning, however, is not straight forward. This paper reports on a study of evaluation processes on a post-graduate, professionally accredited diploma delivered at a selection of post 1992 universities. The driver for the study was a concern that current evaluation processes do not fully demonstrate the value of the course nor take into account the needs of multiple stakeholders. The project included benchmarking University evaluation processes and conducting a dialogue with stakeholders. The study adopted a qualitative management research approach, involving: a review of current practice, comparison with a sample of equivalent courses, and consultation (in the form of focus groups and semi-structured interviews) with a sample of students and employers. The paper discusses findings and proposes recommendations for future evaluation procedures in the design of an ‘educational scorecard’ for the course. Kaplan and Norton’s ‘balanced scorecard (1996) concept was adapted to provide a mechanism to represent and balance the needs of different stakeholder groups in the education process. We argue that we cannot truly assess accountability and comparability without engaging a range of stakeholders, not only in soliciting their views on the outcome of the learning but also in the design and implementation of evaluation processes. The ‘educational scorecard’ presented in this paper is developed specifically for the post-graduate diploma in Human Resource Management (PDHRM) at Leeds Metropolitan University and the report concludes with some initial reflections on the benefits of adopting the scorecard methodology The proposed model is flexible and may be adapted for other HE institutions and courses

Determination of aerosol content in the atmosphere from ERTS-1 data

The author has identified the following significant results. Significant results, relating the radiance over water surfaces to the atmospheric aerosol content, have been obtained. The results indicate that the MSS channels 4, 5, and 6 centered at 0.55, 0.65, and 0.75 microns have comparable sensitivity, and that the aerosol content can be determined within + or - 10% with the assumed measurement errors of the MSS. The fourth channel, MSS 7, is not useful for aerosol determination due to the water radiance values from this channel generally being less than the instrument noise. The accuracy of the aerosol content measurement could be increased by using an instrument specifically designed for this purpose. This radiance-aerosol content relationship can possibly provide a basis for monitoring the atmospheric aerosol content on a global basis, allowing a base-line value of aerosols to be established. The contrast-aerosol content investigation shows useful linear relationships in MSS channels 4 and 5, allowing the aerosol content to be determined within + or - 10%. MSS 7 is not useful due to the low accuracy in the water radiance, and MSS 6 is found to be too insensitive. These results rely on several assumptions due to the lack of ground truth data, but do serve to indicate which channels are most useful

CHARACTERIZATION OF AMBIENT NOISE RECORDED IN THE NORWEGIAN SEA

This thesis characterizes mid-frequency (1–9 kHz) ambient noise collected with an acoustic array over a two-week period in the Norwegian Sea. Noise characterization is an important prerequisite for many applications, including department of defense applications, environmental and biological research. The basic methodology consists of calibrating single hydrophone data for power spectral density (PSD) in dB re 1 μPa^2/Hz. We present omni-directional ambient noise statistics over time, including percentiles and standard deviation for a variety of temporal averages, ranging from 1 to 60 min. These results compare well to historic observations. Wenz suggests spectrum level of approximately 45 (dB re 1 μPa^2/Hz) for a sea state 2, while the result from this thesis finds spectrum level of approximately 43 (dB re 1 μPa2/Hz). Furthermore, results are compared to a wind-based ambient noise model. The model prediction tracks with the data presented relatively well with a slight offset. The slight offset is further explored and gives details of the prevailing sea state. As predicted, the model slightly overestimates the PSD level of the data at sea state 2. This misfit is explored for different sea states and wind speeds.Office of Naval Research, 875 Randolph St., Arlington, VA, 22217NPS Naval Research ProgramThis project was funded in part by the NPS Naval Research Program.Lieutenant, United States NavyApproved for public release.

Consequences of Using Fear as a Motivator and Its Effects on the Employer / Employee Relationship

The following work is an in-depth analysis of the consequences of using fear as a motivator, specifically, in the workplace, and the effects fear has on employees. The empirical research identifies the successful, and often, unsuccessful components of the employer/employee relationship. For many, using fear would seem to be a powerful way of getting employees to produce more, work harder, increasing motivation. This is not always the answer. The study provides reasons why fear can be a negative motivator and detrimental to an organization
