The Management Of Feral Pig Socio-Ecological Systems In Far North Queensland, Australia, Gabriela Shuster
Antioch University Dissertations & Theses
The development of management programs for socio-ecological systems that include multiple stakeholders is a complex process and requires careful evaluation and planning. This is particularly a challenge in the presence of intractable conflict. The feral pig (Sus scrofa) in Australia is part of one such socio-ecological system. There is a large and heterogeneous group of stakeholders interested in pig management. Pigs have diverse effects on wildlife and plant ecology, economic, health, and social sectors. This study used the feral pig management system as a vehicle to examine intractable conflict in socio-ecological systems. The purpose of the study was …

Three Essays On The Efficiency Of Rural Hospitals In The United States, Iustin Cristian Nedelea
LSU Doctoral Dissertations
The Critical Access Hospital (CAH) Program was created in response to the dramatic deterioration of financial conditions and the potential threat of closure of small rural hospitals under the Prospective Payment System (PPS). CAHs receive cost-based reimbursement for services provided to Medicare patients in exchange for accepting a number of restrictions. The PPS, which pays a fixed price per case, provides an incentive for hospitals to reduce costs and increase efficiency. In the first essay, I examine the impact of conversion to CAH status on hospital efficiency. The estimated results show that CAHs are less cost and allocatively efficient than …

Modeling An Improvement In Phosphorus Utilization In Tropical Agriculture, David Edelstein, David J. Tonjes
Technology & Society Faculty Publications
Studies of Terra Preta soils have generated interest in recreating their fertility elsewhere. Much of the research has focused on soil amendment charcoal (“biochar”). Terra Preta also contains bone fragments, producing a high concentration of phosphorus. Some forecast worldwide declines in phosphorus supplies, and better agricultural system management is required to improve phosphorus use efficiency. A conceptual model is offered to consider the influence of charcoal on bioavailability of phosphorus. The model describes a system where improvements in the chemical and biological condition of the soil result in increased phosphorus availability and cycling. Mechanisms of phosphorus/charcoal interaction are considered, and …

Development And Application Of Methods Used To Source Prehistoric Southwestern Maize: A Review, Larry Benson
United States Geological Survey: Staff Publications
Archaeological cobs free of mineral contaminants should be used to source the soils in which they were grown. Mineral contaminants often contain much higher concentrations of metals than vegetal materials and can alter a cob’s apparent metal and heavy-isotope content. Cleaning a cob via immersion in an acid solution for more than a few minutes will result in the incongruent and sometimes complete leaching of metals, including strontium (Sr), from the cob. When using 87Sr/86Sr to determine the location of potential agriculture fields, it is best to either integrate several depth-integrated soil samples or to integrate several …

The priming strategies used were hydropriming, CaCl_2, PEG-8000 (-1.1 M Pa), MLE (concentrate; 1:10, 1:20, 1:30, and 1:40 dilutions with distilled water), and matripriming using saturated jute mat for 24 h. The primed seeds were placed between 2 moist Whatman No. 1 filter …
An Evaluation Of Seed Spacing Accuracy Of A Vacuum Type Precision Metering Unit Based On Theoretical Considerations And Experiments, İsmet Önal, Adnan Deği̇rmenci̇oğlu, Arzu Yazgi
Turkish Journal of Agriculture and Forestry
Currently the most widely used machine for precision seeding of cotton and maize seed is vacuum type. The capture of seeds by vacuum plate and the release of seeds from the vacuum plate should be performed precisely without missing or doubling. The physical phenomena should be clarified theoretically to understand how the precision seeding mechanism works. To solve these problems, an attempt was made to develop a nomogram using equations describing the technical characteristics of the seeder used in this study and to describe the seed capture mechanism relying on basic principles of fluid mechanics and aerodynamic properties of seeds. …

Turkish Journal of Agriculture and Forestry
The impact of pretreatment with high temperature (45 °C for 45 min) on the UV-B tolerance of 4 barley cultivars (Hordeum vulgare L. 'Bülbül-89', 'Kalaycı-97', 'Tarm-92', and 'Tokak-157/37') was examined. The response of the plants to treatment was evaluated by measuring the pigment content, chlorophyll a fluorescence, oxygen evolution, fraction of oxygen-evolving complex, proline content, UV-B-absorbing compounds (A_{535} and A_{300}), and stress markers (malondialdehyde, H_2O_2, and UV-B marker). Regardless of high temperature pretreatment, UV-B irradiation decreased the photosynthetic pigment content, photosystem II activity, oxygen evolution, and the fraction of oxygen-evolving complex in almost all of the barley cultivars. UV-B treatment …
