    Girls without Faces & Other Stories

    Get PDF
    Girls without Faces & Other Stories is a work of magic realist fiction. These are stories in which a starfish speaks, an artist is born with a third eye in her bellybutton, and a young girl is sent to summer camp in a sanatorium to become more creative. These stories observe everyday human thoughts and emotions through a fantastical lens and present the unexpected in a new and honest way

    Understanding the Drivers of Urban Heat; Case Study in Burlington, Vermont

    Get PDF
    Urban Heat Islands (UHI), the phenomenon of cities being hotter than their rural surroundings, are a matter of growing concern as they affect public health, air and water quality, and energy consumption. With predictions by climate scientists for heat waves of increasing intensity and duration, addressing the problem of UHIs has become increasingly urgent. Urban areas experience increased temperatures because of the thermodynamic properties of the materials that make up the built environment, the geometric configuration of buildings and infrastructure, and the relative lack of vegetation. Research in the field has predominantly focused on large cities, neglecting small to midsize cities such as Burlington, Vermont where the UHI effect is also known to exist although population vulnerabilities and infrastructure characteristics may differ from large urban centers. CAPA Strategies has high resolution UHI mapping Burlington, Vermont to map ambient air temperature at a granularity of 10m resolution using mobile sensors. To further address this area of research, a high-resolution heat intensity sample of the city of Burlington, Vermont, USA was created using novel sampling data collected during the summer of 2021 and analysis to find the correlation between impervious surface and urban heat. These sample points were then compared against the CAPA Strategies maps. It was found that the percentage of roads within a buffer are the highest drivers of observed temperature and urban heat in Burlington, Vermont. These findings have implications on mitigation strategies, as well as highlighting the urban heat that exists within mid-size cities such as Burlington, Vermont. The comparison between the high resolution map created using our sampling method and the CAPA map can indicate if this method can be transferred to areas outside of Burlington, Vermont. Through this research I am attempting to address the following questions: What is the correlation between land use, specifically impervious surfaces, and heat intensity in Burlington, Vermont? Do the results across multiple days conform?Looking at places were CAPA data was collected, does the sampling approach mean that our results are substantially different

    Breaking bad news: Penal populism, tabloid adversarialism and Brexit

    Get PDF
    This article analyses the role that British conservative tabloid newspapers play in promoting penal populism and delegitimising liberal prison reform initiatives. Principally, we consider how different sections of the British press reacted to the then Prime Minister David Cameron's prison reform speech of 8 February 2016. The analysis illustrates how different newspapers cohered around two diametrically opposing interpretations of the scandalous state of the prison system, reflecting distinctive penal philosophies and moral positions. In the context of penal populism and the populist furies unleashed by the Brexit campaign, the central research finding is that the comparatively passive and equivocal support offered by the broadsheets was no match for the vitriolic attack mounted by the conservative tabloids on the ‘soft justice’ parts of Cameron's prison reform agenda. We conclude by arguing that the stark lesson to be learned is that the scandal‐ridden prison is a particularly toxic issue marked by serial policy failure. Consequently, in a febrile, intermediatised penal populist context, why would any political leader take on the manifest risks associated with embarking on liberal prison reform

    Acute Effects of Plyometric and Resistance Training on Running Economy in Trained Runners

    Results regarding the acute effects of plyometric and resistance training (PRT) on running economy (RE) are conflicting. Eight male collegiate distance runners (21 +/- 1 years, 62.5 +/- 7.8 ml/kg/min V[Combining Dot Above]O2 peak) completed V[Combining Dot Above]O2 peak and 1 repetition maximum (1RM) testing. Seven days later, subjects completed a 12 minute RE test at 60% and 80% V[Combining Dot Above]O2 peak, followed by a PRT protocol or a rested condition of equal duration (CON). The PRT protocol consisted of 3 sets of 5 repetitions at 85% 1RM for barbell squats, Romanian deadlifts, and barbell lunges; the same volume was utilized for resisted lateral lunges, box jumps, and depth jumps. Subjects completed another RE test immediately following the treatments as well as 24 hours later. Subjects followed an identical protocol six days later with condition assignment reversed. RE was determined by both relative V[Combining Dot Above]O2 (ml/kg/min) as well as energy expenditure (kcal/min). There was a significant (p \u3c 0.05) between-trial increase in V[Combining Dot Above]O2 (37.1 +/- 4.2 ml/kg/min PRT vs. 35.5 +/- 3.9 ml/kg/min CON) and energy expenditure (11.4 +/- 1.3 kcal/min PRT vs. 11.0 +/- 1.4 kcal/min CON) immediately post-PRT at 60% V[Combining Dot Above]O2 peak, but no significant changes were observed at 80% V[Combining Dot Above]O2 peak. Respiratory exchange ratio (RER) was significantly (p \u3c 0.05) reduced 24 hours post-PRT (0.93 +/- 0.0) as compared to the CON trial (0.96 +/- 0.0) at 80% V[Combining Dot Above]O2 peak. Results indicate that high intensity PRT may acutely impair RE in aerobically trained individuals at a moderate running intensity, but that the attenuation lasts less than 24 hours in duration

    Dynamical Monte Carlo Study of Equilibrium Polymers : Static Properties

    Full text link
    We report results of extensive Dynamical Monte Carlo investigations on self-assembled Equilibrium Polymers (EP) without loops in good solvent. (This is thought to provide a good model of giant surfactant micelles.) Using a novel algorithm we are able to describe efficiently both static and dynamic properties of systems in which the mean chain length \Lav is effectively comparable to that of laboratory experiments (up to 5000 monomers, even at high polymer densities). We sample up to scission energies of E/kBT=15E/k_BT=15 over nearly three orders of magnitude in monomer density ϕ\phi, and present a detailed crossover study ranging from swollen EP chains in the dilute regime up to dense molten systems. Confirming recent theoretical predictions, the mean-chain length is found to scale as \Lav \propto \phi^\alpha \exp(\delta E) where the exponents approach αd=δd=1/(1+γ)0.46\alpha_d=\delta_d=1/(1+\gamma) \approx 0.46 and αs=1/2[1+(γ1)/(νd1)]0.6,δs=1/2\alpha_s = 1/2 [1+(\gamma-1)/(\nu d -1)] \approx 0.6, \delta_s=1/2 in the dilute and semidilute limits respectively. The chain length distribution is qualitatively well described in the dilute limit by the Schulz-Zimm distribution \cN(s)\approx s^{\gamma-1} \exp(-s) where the scaling variable is s=\gamma L/\Lav. The very large size of these simulations allows also an accurate determination of the self-avoiding walk susceptibility exponent γ1.165±0.01\gamma \approx 1.165 \pm 0.01. ....... Finite-size effects are discussed in detail.Comment: 15 pages, 14 figures, LATE
