How might the co-creation of a situated working woodland begin to address some of the major pedagogical challenges of our time?

This thesis was written alongside the practical realisation of a new working woodland provision for young adults with special educational needs (SEN) in the West Midlands of the United Kingdom. The thesis traces the journey of the ‘responsable’ through the three-year design and implementation process in the hope that his experiences may offer insight into whether and how the co-creation of and co-operation of a working woodland may be of pedagogical value in these times. The essay sets out by defining just what is meant by ‘these/our times’, examining the current educational context, and considering current patterns and consequences of human orientation and activity on the planet, looking at depth into our relationship with nature and craft. Next, the author offers an auto-ethnographical account of his journey ‘here’, describing his experience through the modern education system, and his journey ‘into the woods’. Finally, the thesis outlines the nature of a ‘working woodland’, and examines the extent to which such a venture may begin to tackle the challenges described earlier in the report

The effects of daily fluctuating temperatures and dimethylnaphthalene contaminated food on the estuarine grass shrimp, palaemonetes pugio

The physiological effects of a natural perturbation (fluctuating. temperatures) and a petroleum-induced perturbation. (dimethylnaphthalene-contaminated food) on the grass shrimp. Palaemonetes pugio were compared. The resistance of shrimp to. environmental challenge, oxygen consumption rates (Vo(,2)) and(\u27 ). several physiological indices of stress were determined after a 32. day exposure to fluctuating temperatures (FT) (18-22�C) and/or dimethylnaphthalene (DMN)-contaminated food (0.24 (mu)g DMN/g wet wt) and again after a 16 day recovery period of stable temperatures (20�C) and uncontaminated food. Both FT and DMN-contaminated food reduced survival to the challenge of hypoxia + reduced salinity. FT were quantitatively more stressful than either stable temperatures or DMN-contaminated food. After the recovery period, FT did not affect survival to hypoxia, while shrimp, which had ingested DMN-contaminated food, exhibited enhanced survival to hypoxia. Ingestion of DMN-contaminated food for 32 days resulted in elevated Vo(,2)(\u27 )in shrimp exposed to declining oxygen concentrations. After the 32 day exposure period, FT had no significant effect on(\u27 )Vo(,2) at 15�C, 20�C and 25�C, tissue Vo(,2),(\u27 )Vo(,2) in declining oxygen and hemolymph copper concentrations. After the 16 day recovery period, shrimp from the FT regime exhibited depressed(\u27 )Vo(,2) when exposed to 25�C but not to 15�C. These depressed respiratory rates were offset by the stimulatory effect of DMN-contaminated food. The ratio of oxygen consumed to nitrogen excreted wwas elevated after the exposure and recovery periods in shrimp exposed to both FT and DMN-contaminated food at the same time. Water flux rates were elevated by FT after the exposure and recovery periods but not when DMN-contaminated food was also ingested. Both water flux rates and the ratio of oxygen consumed to nitrogen excreted were elevated in all shrimp after the recovery period relative to levels observed after the exposure period. After the exposure period, FT induced elevated hemolymph acid phosphatase activities in shrimp exposed to hypoxia. After the recovery period, hypoxia induced elevated hemolymph acid phosphatase activities in shrimp which had ingested nothing but uncontaminated food relative to those ingesting DMN-contaminated food

Localization and delocalization in two-dimensional quantum percolation

Quantum percolation is one of several disorder-only models that address the question of whether conduction, or more generally, delocalization, is possible in two dimensional disordered systems. Whether quantum percolation exhibits a delocalization-localization phase transition in two dimensions is an ongoing debate, but many recent studies point toward there being a delocalized phase at non-zero disorder, in contradiction to the behavior of the Anderson model, another disorder-only model. In this dissertation, I present my research on quantum percolation that shows a delocalized state is possible, both on isotropic lattices and on highly anisotropic lattices, and shows that the essential characteristics of the quantum percolation model are maintained even when the model is modified to allow tunneling through diluted sites. In Chapter 1, I provide an overview of the scaling theory for the Anderson model, the history of the quantum percolation model, and the computational methods used to study the quantum percolation model in two dimensions. In Chapter 2, I study the two-dimensional quantum percolation model with site percolation on isotropic square lattices using numerical calculations of the transmission coefficient T on a much larger scale and over a much wider range of parameters than was done previously. I confirm the existence of delocalized, power-law localized, and exponentially localized phases, and determine a detailed, quantitative phase diagram for energies 0.001 ≤ E ≤ 1.6 and dilutions 2% ≤ q ≤ 38%. Additionally, I show that the delocalized phase is not merely a finite size effect. In Chapter 3, I examine the same 2D quantum percolation model on highly anisotropic strips of varying width, to investigate why the isotropic lattice results show a delocalized phase, unlike work by others on anisotropic strips, in particular that of Soukoulis and Grest [Phys. Rev. B 44, 4685 (1991)] using the transfer matrix method . The model is studied over a dilution range extending to lower dilutions than those studied by Soukoulis and Grest, and I find evidence of a delocalized phase at these low dilutions, with phase boundaries that agree with my previous work. In Chapter 4, I modify the 2D quantum percolation model to allow for tunneling through and between diluted sites by making the hopping integral for diluted sites be a non-zero fraction of the hopping integral for occupied sites, while yet maintaining a binary disorder. Using numerical calculations of the transmission coefficient T as in Chapter 1, I determine a complete, detailed three-parameter phase diagram showing the effects of energy E, dilution q, and hopping integral w. I find that the three phases characteristic of quantum percolation persist for a fairly large range of w before the entire system becomes delocalized at sufficiently large w. Additionally, I examine the inverse participation ratio (IPR) to gain a complementary picture of how the particle’s wave function changes with respect to q and w. Lastly, in Chapter 5 I present my analysis and conclusions

An ROI Comparison of Initiatives Designed to Attract Diverse Students to Technology Careers

This study examines two alternative interventions designed to attract diverse students to pursue information technology or, more generally, STEM (science, technology, engineering, and math) careers from a Return on Investment (ROI) perspective. More specifically, this study examines the effectiveness and efficiency of single-day and multi-day program formats by comparing students’ propensity to pursue computer information systems and technology related careers. Using an ROI perspective of comparing relative costs to students’ perceived outcomes, our findings suggest that the single-day model is equally effective as the multi-day model at moving students’ propensity to pursue information technology careers, albeit at a lower cost. This suggests that the single day model is a better choice from an ROI perspective and offers the best investment opportunity for choosing which program format to use for future interventions. These findings, while specific to a single comparison of two alternative information technology interventions, are useful as they contribute valuable knowledge and may be applicable to the design and evaluation of other STEM-influencing programs
