Economic Analysis and Impact of Sod Production in Texas
This paper presents analysis of the cost structure for a medium-sized sod producing operation in Texas and results of a mail survey providing information on the production economics and marketing of sod in Texas. Results are compared with findings from previous studies conducted in Florida and Alabama.Crop Production/Industries,
A new paradigm for SpeckNets:inspiration from fungal colonies
In this position paper, we propose the development of a new biologically inspired paradigm based on fungal colonies, for the application to pervasive adaptive systems. Fungal colonies have a number of properties that make them an excellent candidate for inspiration for engineered systems. Here we propose the application of such inspiration to a speckled computing platform. We argue that properties from fungal colonies map well to properties and requirements for controlling SpeckNets and suggest that an existing mathematical model of a fungal colony can developed into a new computational paradigm

Journeys to Open Educational Practice: UKOER/SCORE Review Final Report
In 2008 the JISC Good Intentions report concluded that the landscape around learning materials had changed sufficiently to support a range of sustainable models for sharing. The report charted and acknowledged the long history of approaches to support sharing that had helped to shape the landscape.
Most of the models highlight a growing acknowledgement of the need to build and support open and sustainable communities to share practice and resources. Indeed such communities are often the key to sustaining the service, whichever model is adopted. This is the type of model most likely to encourage sharing between teachers as well as learners.
The growing OER community is taking collaborative approaches to tackling the ongoing challenges of raising awareness, licensing and trust issues, and standards and technologies. The challenge for the UK now is to ensure that our HE institutions are enabled to create policies, practices and support their staff to accelerate the transformations required to contribute and benefit from this global movement. It is also vital to ensure that we capture the real picture of use and re-use of such services and collections to inform future OER programmes.
HEFCE funding for OER initiatives followed this report in 2009 and has, in many ways, provided some of the scaffolding and support for a variety of individuals, communities and institutions to move forwards in their own journeys, whether they started years before in other contexts or had just joined on the road to open sharing
Generalised dimensions of measures on almost self-affine sets
We establish a generic formula for the generalised q-dimensions of measures
supported by almost self-affine sets, for all q>1. These q-dimensions may
exhibit phase transitions as q varies. We first consider general measures and
then specialise to Bernoulli and Gibbs measures. Our method involves estimating
expectations of moment expressions in terms of `multienergy' integrals which we
then bound using induction on families of trees
EVALUATING APPROPRIATE RENTAL RATES FOR RICE ACREAGE
The levels and risk-free nature of rice market transition payments associated with the FAIR Act of 1996 have encouraged many rice landowners to reconsider their tenure contracts. A methodology for comparing landowners' decision to "self-operate" versus "rent to a tenant" is presented.Crop Production/Industries, Land Economics/Use,
Persistent organic pollutants in the Atlantic and southern oceans and oceanic atmosphere
Persistent organic pollutants (POPs) continue to cycle through the atmosphere and hydrosphere despite banned or severely restricted usages. Global scale analyses of POPs are challenging, but knowledge of the current distribution of these compounds is needed to understand the movement and long-term consequences of their global use. In the current study, air and seawater samples were collected Oct. 2007āJan. 2008 aboard the Icebreaker Oden en route from Gƶteborg, Sweden to McMurdo Station, Antarctica. Both air and surface seawater samples consistently contained Ī±-hexachlorocyclohexane (Ī±-HCH), Ī³-HCH, hexachlorobenzene (HCB), Ī±-Endosulfan, and polychlorinated biphenyls (PCBs). Sample concentrations for most POPs in air were higher in the northern hemisphere with the exception of HCB, which had high gas phase concentrations in the northern and southern latitudes and low concentrations near the equator. South Atlantic and Southern Ocean seawater had a high ratio of Ī±-HCH to Ī³-HCH, indicating persisting levels from technical grade sources. The Atlantic and Southern Ocean continue to be net sinks for atmospheric Ī±-, Ī³-HCH, and Endosulfan despite declining usage
A DECISION SUPPORT AID FOR BEEF CATTLE INVESTMENT USING EXPERT SYSTEMS
The beef cattle investment decision provides an excellent opportunity to increase the economic efficiency of beef cattle production. The investment questions that face beef cattle producers are of interest to beef cattle producers, educators, and financial institutions involved in lending to beef cattle producing firms. This study develops a decision support aid utilizing expert system technology to assist beef cattle producers in making well-founded investment decisions with respect to the firm's beef cattle herd.Beef cattle investment, Decision support, Export systems, Livestock Production/Industries,
Economic Analysis of High Fertilizer Input, Over-seeded Clover and Native Pasture Production Systems in the Texas Coastal Bend
This paper examined the cost and risk of three grazing systems to provide information on economically sustainable systems for cattle producers in the Texas Coastal Bend. Results indicate the medium input (over-seeded clover) grazing system displays first degree stochastic dominance relative to the high input and no input grazing systems.grazing system economics, forage production economics, Crop Production/Industries, Livestock Production/Industries, Production Economics,
A multifractal zeta function for cookie cutter sets
Starting with the work of Lapidus and van Frankenhuysen a number of papers
have introduced zeta functions as a way of capturing multifractal information.
In this paper we propose a new multifractal zeta function and show that under
certain conditions the abscissa of convergence yields the Hausdorff
multifractal spectrum for a class of measures
