Homophobia, Heterosexism, and Ambivalence in the Premier Issue of \u3cem\u3eSports Illustrated Woman/Sport\u3c/em\u3e

The arrival of a magazine dedicated solely to the world of women\u27s sports was an exciting prospect for fans and proponents of women\u27s sports. But the first issue of Sports Illustrated Women/Sport disappointed many who considered it did not put women\u27s sports in the best possible light, who were worried and disappointed that its editors did not print the best stories or even focus on the most deserving athletes. Lisa Weidman decided to investigate further, using feminist theory and prior research findings to better understand the magazine\u27s messages. Through a critical analysis of the magazine\u27s editorial content - at the same time recognizing its advertisement, an aspect worthy of study - Weidman demonstrates how the first issue of Women/Sport marginalized women\u27s sports, expressed ambivalence about women\u27s participation in sports, and perpetuated homophobic and heterosexist attitudes

Eco-terrorism or Eco-tage: An Argument for the Proper Frame

What does the term “terrorism” mean? Is it accurate to lump illegal acts that destroy property but carefully avoid harming people into the same category as acts clearly intended to kill? Is this a difference of kind or just of degree? While we (the authors) don\u27t generally endorse the destruction of property as a method of generating social change, we believe that the destruction of property is fundamentally different from the intentional killing of people; therefore, to label acts of obstruction, trespassing, vandalism, sabotage, or arson as “terrorism” is inaccurate and has the potential to damage one\u27s understanding of real acts of terrorism, thereby reducing the potency of the term. We started this project with a hunch. In recent years, we have observed frequent use of the term “eco-terrorism,” in the news media and in conversations, in reference to the acts of environmentalists. Our observations were anecdotal, and we wanted to be sure they were accurate. We found no literature analyzing cultural acceptance of the term “eco-terrorism”; therefore, before embarking on an ethical analysis of this phenomenon, we set out to confirm our casual observation that the term was widely used in the United States. We conducted an analysis of the use of the term in US newspapers across a period of nearly 11 years. Our analysis indicates broad acceptance of the term among both journalists and their sources, making it all the more important to understand both the history and the implications of labeling obstruction, trespassing, vandalism, sabotage, and arson as “eco-terrorism.

Oscillatory oblique stagnation-point flow toward a plane wall

Two-dimensional oscillatory oblique stagnation-point flow toward a plane wall is investigated. The problem is a eneralisation of the steady oblique stagnation-point flow examined by previous workers. Far from the wall, the flow is composed of an irrotational orthogonal stagnation-point flow with a time-periodic strength, a simple shear flow of constant vorticity, and a time-periodic uniform stream. An exact solution of the Navier-Stokes equations is sought for which the flow streamfunction depends linearly on the coordinate parallel to the wall. The problem formulation reduces to a coupled pair of partial differential equations in time and one spatial variable. The first equation describes the oscillatory orthogonal stagnation-point flow discussed by previous workers. The second equation, which couples to the first, describes the oblique component of the flow. A description of the flow velocity field, the instantaneous streamlines, and the particle paths is sought through numerical solutions of the governing equations and via asymptotic analysis

Applicability of ERTS-1 to Montana geology

The author has identified the following significant results. Late autumn imagery provides the advantages of topographic shadow enhancement and low cloud cover. Mapping of rock units was done locally with good results for alluvium, basin fill, volcanics, inclined Paleozoic and Mesozoic beds, and host strata of bentonite beds. Folds, intrusive domes, and even dip directions were mapped where differential erosion was significant. However, mapping was not possible for belt strata, was difficult for granite, and was hindered by conifers compared to grass cover. Expansion of local mapping required geologic control and encountered significant areas unmappable from ERTS imagery. Annotation of lineaments provided much new geologic data. By extrapolating test site comparisons, it is inferred that 27 percent of some 1200 lineaments mapped from western Montana represent unknown faults. The remainder appear to be localized mainly by undiscovered faults and sets of minor faults or joints

Applicability of ERTS-1 to lineament and photogeologic mapping in Montana: Preliminary report

A lineament map prepared from a mosaic of western Montana shows about 85 lines not represented on the state geologic map, including elements of a northeast-trending set through central western Montana which merit ground truth checking and consideration in regional structural analysis. Experimental fold annotation resulted in a significant local correction to the state geologic map. Photogeologic mapping studies produced only limited success in identification of rock types, but they did result in the precise delineation of a late Cretaceous or early Tertiary volcanic field (Adel Mountain field) and the mapping of a connection between two granitic bodies shown on the state map. Imagery was used successfully to map clay pans associated with bentonite beds in gently dipping Bearpaw Shale. It is already apparent that ERTS imagery should be used to facilitate preparation of a much needed statewide tectonic map and that satellite imagery mapping, aided by ground calibration, provides and economical means to discover and correct errors in the state geologic map

Electro-optic characterization of synthesized infrared-visible light fields

The measurement and control of light field oscillations enable the study of ultrafast phenomena on sub-cycle time scales. Electro-optic sampling (EOS) is a powerful field characterization approach, in terms of both sensitivity and dynamic range, but it has not reached beyond infrared frequencies. Here, we show the synthesis of a sub-cycle infrared-visible pulse and subsequent complete electric field characterization using EOS. The sampled bandwidth spans from 700 nm to 2700 nm (428 to 110 THz). Tailored electric-field waveforms are generated with a two-channel field synthesizer in the infrared-visible range, with a full-width at half-maximum duration as short as 3.8 fs at a central wavelength of 1.7 µm (176 THz). EOS detection of the complete bandwidth of these waveforms extends it into the visible spectral range. To demonstrate the power of our approach, we use the sub-cycle transients to inject carriers in a thin quartz sample for nonlinear photoconductive field sampling with sub-femtosecond resolution

Efficient Nanosecond Photoluminescence from Infrared PbS Quantum Dots Coupled to Plasmonic Nanoantennas

Infrared (IR) light sources with high modulation rates are critical components for on-chip optical communications. Lead-based colloidal quantum dots are promising nonepitaxial materials for use in IR light-emitting diodes, but their slow photoluminescence lifetime is a serious limitation. Here we demonstrate coupling of PbS quantum dots to colloidal plasmonic nanoantennas based on film-coupled metal nanocubes, resulting in a dramatic 1300-fold reduction in the emission lifetime from the microsecond to the nanosecond regime. This lifetime reduction is primarily due to a 1100-fold increase in the radiative decay rate owing to the high quantum yield (65%) of the antenna. The short emission lifetime is accompanied by high antenna quantum efficiency and directionality. This nonepitaxial platform points toward GHz frequency, electrically modulated, telecommunication wavelength light-emitting diodes and single-photon sources.United States. Dept. of Energy.
