Strategies to Improve Recycling in Natural Areas: Examples from Zion National Park

The next life of a product, either a landfill or recycling center, is largely dependent on which bin products are placed in. As important as this may be, many people throw recyclable commodities in the trash, wasting valuable resources. ecause it is difficult to encourage sustainable behavior, this fact sheet outlines tips to increase the ease and accuracy of recycling in high traffic areas, using Zion National Park as a case study

Treasure in Jars of Clay: Towards a new Pauline Pastoral Theology of Mission to Generation Y in Australia

Within the contemporary Australian context, it is evident that the young people who represent Generation Y (born, 1981 – 1995) are not engaged by a Christian faith. This thesis will set out an approach that will seek to re-envisage the transmission of a Christian faith to the members of Generation Y in Australia through a Pauline pastoral theology of mission. Hence, this thesis aims: 1. To provide a theological hermeneutic of pastoral mission that may be a partner in dialogue with other approaches to ministry among Generation Y. 2. To assist the Christian churches in their consideration of some of the issues surrounding the general absence of Generation Y in their communities by drawing on scripture as a historical source of Christian theology. 3. To serve Generation Y with a pastoral response that endeavours both to draw from the foundational elements of the Christian faith and to suggest theological conclusions fitting for the post-modern world they inhabit. The methodological structure of this thesis is based upon Whitehead and Whitehead’s theological process of ‘attending’, ‘asserting’ and ‘deciding’. In ‘attending’, this thesis engages with sociological, psychological, neurophysiological and theological data regarding the spirituality of Generation Y in Australia. It also ‘attends’ to a Pauline theology of faith as it is presented in the text of 2 Corinthians 4. Further, it brings the worlds of Paul and Generation Y into dialogue and ‘assertion’ through the epistemology and theology of mission of Lesslie Newbigin. The final phase of this thesis involves the proposal of a set of pastoral dispositions (habitus) which may guide the ‘decisions’ of the Christian churches as they seek to reach out to Generation Y in mission. Three fields of mission – authenticity, proximity and intelligibility – are considered in relation to an encounter between Australia’s Christian churches and Generation Y. Through this process a new Pauline habitus of transmission is offered. The missional roles of kenosis, patience and apprenticeship in the Christian tradition are all discussed as ways that the Christian churches may re-engage with Generation Y in Australia through a renewed disposition of mission.

Effects of ultrafast laser energy deposition on a hypervelocity boundary layer

This paper presents a preliminary study of hypersonic boundary layer phenomena resulting from the energy deposition of an ultrafast laser pulse in proximity to the tip of a 7° half-angle axisymmetric cone within the Oxford High Density Tunnel (HDT) facility. An ultrafast Ti:Sapphire laser was integrated into the facility’s systems, providing temporally precise and synchronous delivery of a single tightly focussed laser pulse to the target location in the HDT test section. This investigation independently assessed the variation of the freestream unit Reynolds number (Reunit,∞) on the disturbed boundary layer for laminar to turbulent conditions bound by the extrema unit Reynolds numbers 5.7 and 24.1 ± 0.9 × 106/m, while keeping laser settings constant. For all test conditions, the boundary layer state was characterised using high-speed schlieren imaging at 1 MHz for visualising the flow field, focussed laser differential interferometry (FLDI) to assess small density fluctuations, and surface-mounted highfrequency bandwidth pressure transducers (PCBs 132A31 and 132B32). Flow features associated with the energy deposition in the boundary layer, included the formation of a spherical shock wave that expanded radially and decayed, an elliptical high-temperature ‘hot spot’ region, and a trailing turbulent wake. The hot spot and turbulent wake density gradients increased linearly with unit Reynolds number, suggesting a relation to the local mean density or pressure. Normalising these values by mean density gave an estimate of turbulence intensity, which appeared independent of unit Reynolds number. The size of the hot spot decreased with unit Reynolds number, which is hypothesised to be caused by the higher mean pressure compressing the hot spot. The increasing instability of the boundary layer with unit Reynolds number led to longer duration turbulent wakes before the laminar boundary layer re-establishes

Anxious/depressed symptoms are related to microstructural maturation of white matter in typically developing youths

AbstractThere are multiple recent reports of an association between anxious/depressed (A/D) symptomatology and the rate of cerebral cortical thickness maturation in typically developing youths. We investigated the degree to which anxious/depressed symptoms are tied to age-related microstructural changes in cerebral fiber pathways. The participants were part of the NIH MRI Study of Normal Brain Development. Child Behavior Checklist A/D scores and diffusion imaging were available for 175 youths (84 males, 91 females; 241 magnetic resonance imagings) at up to three visits. The participants ranged from 5.7 to 18.4 years of age at the time of the scan. Alignment of fractional anisotropy data was implemented using FSL/Tract-Based Spatial Statistics, and linear mixed model regression was carried out using SPSS. Child Behavior Checklist A/D was associated with the rate of microstructural development in several white matter pathways, including the bilateral anterior thalamic radiation, bilateral inferior longitudinal fasciculus, left superior longitudinal fasciculus, and right cingulum. Across these pathways, greater age-related fractional anisotropy increases were observed at lower levels of A/D. The results suggest that subclinical A/D symptoms are associated with the rate of microstructural development within several white matter pathways that have been implicated in affect regulation, as well as mood and anxiety psychopathology.</jats:p

The plasticity of near space: evidence for contraction

The distinction between near space and the space farther away has been well established, as has the relation of this distinction to arm length. Recent studies provide evidence for the plasticity of near space, showing that it is possible to expand its extent ("size") through tool-use. In the present study, we examine the converse effect, whether contraction of near space results from increasing the effort involved on a line bisection task. Adult participants bisected lines at different distances, while, in some cases, wearing weights. In Experiment 1, the arms, specifically, were weighted (wrist weights), and in Experiment 2, more general body weights were used (heavy backpack). As in previous studies, unencumbered participants showed leftward bias when bisecting lines at the closest distances and a rightward shift in bias with increasingly farther distances. With wrist weights, but not a heavy backpack, participants showed more rightward bias at the closest distances, and a more gradual rightward shift with increasing distance, as if the nearest locations were represented as being farther away. These results suggest that increased effort, when specifically related to the arm, can serve to reduce the size of near space, providing support for the generally symmetrical plasticity of near space representations
