Foot-Notes
The major disagreement here is that Foot, contra Kant, denies that moral ends are ends that the agent has a duty to adopt. Though I, in part, agree with Foot, it is difficult to see what is paradoxical about the view that she denies. Foot’s position is the one that appears paradoxical. Her position is that I may have duties within morality, but I cannot have a duty to adopt the ends of morality. On the contrary, morality is inescapable
Market Structure, Organizational Structure, and R&D Diversity
We examine the effects of market structure and the internal organization of firms on equilibrium R&D projects. We compare a monopolist's choice of R&D portfolio to that of a welfare maximizer. We next show that Sah and Stiglitz's finding that the market portfolio of R&D is independent of the number of firms under Bertrand competition extends to neither Cournot oligopoly nor a cartel. We also show that the ability of firms to pre-empt R&D by rivals along particular research paths can lead to socially excessive R&D diversification. Lastly, using Sah and Stiglitz's definition of hierarchy, we establish conditions under which larger hierarchies invest in smaller portfolios.
Scalable Wavelet-Based Active Network Stepping Stone Detection
Network intrusions leverage vulnerable hosts as stepping stones to penetrate deeper into a network and mask malicious actions from detection. This research focuses on a novel active watermark technique using Discrete Wavelet Transformations to mark and detect interactive network sessions. This technique is scalable, nearly invisible and resilient to multi-flow attacks. The watermark is simulated using extracted timestamps from the CAIDA 2009 dataset and replicated in a live environment. The simulation results demonstrate that the technique accurately detects the presence of a watermark at a 5% False Positive and False Negative rate for both the extracted timestamps as well as the empirical tcplib distribution. The watermark extraction accuracy is approximately 92%. The live experiment is implemented using the Amazon Elastic Compute Cloud. The client system sends marked and unmarked packets from California to Virginia using stepping stones in Tokyo, Ireland and Oregon. Five trials are conducted using simultaneous watermarked and unmarked samples. The live results are similar to the simulation and provide evidence demonstrating the effectiveness in a live environment to identify stepping stones
Experimental study of hydro-mechanical behaviour of granular materials
Inadequate knowledge of the behaviour of wet granular materials such as unsaturated
soils or wet and sticky industrial bulk solids formed the basis of the current research
project in which selected granular materials were experimentally characterised. The
main objective was to investigate the hydro-mechanical behaviour. Specifically, the
following were studied: effect of particle size, particle shape, drying-wetting cycles and
void ratio on the water retention behaviour of granular materials, and effect of suction
on the shear behaviour and flowability of granular materials. A total of 85 pressure plate
tests, 13 triaxial compression tests with the axis translation technique used to control
suction in unsaturated tests and 52 silo model tests were successfully conducted to
respectively measure water retention characteristics, stress-strain and shear strength, and
flowability of glass beads of high sphericity (~95% roundness) and Leighton Buzzard
sand (~82% roundness). With these deliberately simple materials each considered factor
was isolated and investigated at a time something hugely challenging to achieve with
many unsaturated soils.
Many pertinent features of hydro-mechanical behaviour observed for most soils were
well captured with spherical glass beads meaning that particle-water interaction alone
can produce the typical unsaturated behaviour and the particle size and shape
significantly affected the behaviour. Further drying-wetting cycles did not alter the
WRCs of both glass beads and sand except in the saturated capillary regime suggesting
that factors other than the inert water-particle interaction through the liquid bridges are
responsible for the discrepancy between the first drying-wetting cycle WRC and the
subsequent drying-wetting cycles WRCs often observed in clayey soils. It’s discovered
that the additional inter-particle bonding force introduced through the liquid bridges
maintained by the matric suction serves to increase the stiffness, volumetric stability
and shear strength of the material. The rate of increase of strength diminished with
increase in matric suction. The study noted that the Beverloo law is valid for estimation
of the dry mass discharge rate and that moisture alone is sufficient to maintain stable
arching action depending on the hopper outlet. The study generated new knowledge in
form of the effect of the material particle properties on the bulk hydro-mechanical
behaviour of granular materials. An approach has also been proposed for estimating the
flowability and minimum hopper outlet diameter for the wet noncohesive bulk solids
Development of Agroecology Based Garden System and Educational Program at Grand Valley State University
This study was part of a twelve- week project to introduce agroecology growing principles and educational models at the Community Garden on the campus of Grand Valley State University in Allendale, Michigan. This project was set up to be a demonstration for the further development of the garden space as an area for agroecology focused education, extension, and outreach. To accomplish this, three areas of change became essential components to developing a garden space that can serve as a living laboratory, demonstration area, and outdoor classroom. The first project goal was to develop and create a demonstration garden plot that would include diverse growing models in order to explore the best land management practices for small- scale community garden growing. The second project goal was to develop an agriculture education program that would include preschool students, K-12 students, and university students. These programs would be instrumental in introducing students to the diverse topics in agricultural education and to present the opportunity to experience working in outdoor fieldwork that adheres to ecologically aware principles. The third project goal was to use sustainability as a measure of the quality of our garden management while determining how to assess the environmental, resource consumption, and economic impacts of our garden. The purpose of this twelve- week project was to initiate a preliminary project to expand research and education in the future at the community garden site. The purpose of this paper is to provide a summary of the work that was done throughout the summer as this project was sponsored by the Undergraduate Research Council at Grand Valley State University as part of the Student Summer Scholars (S3) grant program
Lime requirement of pond soils for aquaculture around Cochin backwaters
The use of lime in pond fish culture has been advocated by fish culturists over a large part of the world. Liming increases the pH of bottom mud and thereby increases the availability of phosphorous added as fertilizer. The application of lime to improve the fertility as well as production is already being practiced by traditional farmers and aquaculturists in the culture systems bordering the Cochin Backwaters and the Vembanad Lake. In the present investigation soil samples were collected from different seasonal and perennial prawn culture fields during the premonsoon and monsoon seasons. The samples were estimated for their lime requirement during both the seasons
