Neoliberalism Goes to School: Neoliberalism\u27s Influence on Responses to Sexual Violence in Higher Education Institutions
This paper will begin by tracing the historical relationship between sexual violence and race, and then describe how neoliberalism compounded upon this history to create a carceral feminist response to sexual violence. After outlining the neoliberal trends present in national responses to sexual violence, I will narrow my focus to responses within higher education and attempt to demonstrate the parallels between them. I will focus on the commonalities of punitive responses and individualization, which result in a culture of compliance in higher education. I will conclude by describing alternatives to the current way higher education executes Title IX policy
Movement of Trace Elements During Residence in the Antarctic Ice: a Laboratory Simulation
Recent work has determined that differences in the trace element distribution between Antarctic eucrites and non-Antarctic eucrites may be due to weathering during residence in the ice, and samples that demonstrate trace element disturbances do not necessarily correspond to eucrites that appear badly weathered to the naked eye. This study constitutes a preliminary test of the idea that long-term residence in the ice is the cause of the trace element disturbances observed in the eucrites. Samples of a non-Antarctic eucrite were leached in water at room temperature conditions. Liquid samples were analyzed for rare earth element abundances using ion chromatography. The results for the short-term study showed little or no evidence that leaching had occurred. However, there were tantalizing hints that something may be happening. The residual solid samples are currently being analyzed for the unleached trace metals using instrumental neutron activation analysis and should show evidence of disturbance if the chromatography clues were real. In addition, another set of samples continues to be intermittently sampled for later analysis. The results should give us information about the movement of trace elements under our conditions and allow us to make some tentative extrapolations to what we observe in actual Antarctic eucrite samples
High Intrinsic Mobility and Ultrafast Carrier Dynamics in Multilayer Metal Dichalcogenide MoS2
The ultimate limitations on carrier mobilities in metal dichalcogenides, and
the dynamics associated with carrier relaxation, are unclear. We present
measurements of the frequency-dependent conductivity of multilayer
dichalcogenide MoS2 by optical-pump terahertz-probe spectroscopy. We find
mobilities in this material approaching 4200 cm2/Vs at low temperatures. The
temperature dependence of scattering indicates that the mobility, an order of
magnitude larger than previously reported for MoS2, is intrinsically limited by
acoustic phonon scattering at THz frequencies. Our measurements of carrier
relaxation reveal picosecond cooling times followed by recombination lasting
tens of nanoseconds and dominated by Auger scattering into defects. Our results
provide a useful context in which to understand and evaluate the performance of
MoS2-based electronic and optoelectronic devices.Comment: 13 pages, 8 figure
The Impact of Multi-Layered Diffusionary Processes on Musical Evolution: The Global Nature, and Hawaiian, Spanish and African Roots of Delta Blues Culture
As a distinct musical form, blues music from the Mississippi Delta has been extensively studied by musicologists, ethnomusicologists, historians and folklorists. As has been the case with the larger public attracted to this intriguing musical genre, much of this academic attention has treated blues as just that - something one listens to. We argue that blues represents far more than just sound or entertainment, rather it represents a broad cultural milieu from which a distinctive musical culture evolved. Moreover, the musical evolution associated with blues did not occur in a vacuum, it was generated and facilitated by various forms of cultural exchange occurring over time and space. Further, the forms of cultural exchange responsible for the evolution of Delta blues culture were and continue to be truly global in scope. In this paper, by highlighting Hawaiian, Spanish and African influences, we discuss the geographical processes associated with the evolution of blues music and focus on the multi-layered forms of global diffusion responsible for what has been referred to as “Delta blues.” Through a discussion of this form of blues music, we focus attention on the complex inter-relationships evident between and among different people and different places, and highlight how global interactions generated a truly unique music form
Evaluation of the mean excitation energy of liquid argon
Current and future experiments need to know the stopping power of liquid
argon. It is used directly in calibration, where commonly the minimum-ionizing
portion of muon tracks is used as a standard candle. Similarly, muon range is
used as a measure of muon energy. More broadly, the stopping power figures into
the simulation of all charged particles, and so uncertainty propagates widely
throughout data analysis of all sorts. The main parameter that controls
stopping power is the mean excitation energy, or I-value. Experimental
information for argon's I-value come primarily from measurements of gaseous
argon, with a very limited amount of information from solid argon, and none
from liquid argon. These measurements are reviewed, along with a discussion of
the difference in central value and uncertainty incurred by the difference of
phase. The values newly recommended by this note are eV for
gaseous argon and eV for liquid argon (68% C.L. in each case).Comment: 6 pages, 1 figur
