Variability and trends in stratospheric NO2 in Antarctic summer, and implications for stratospheric NOy

NO2 measurements during 1990-2007, obtained from a zenith-sky spectrometer in the Antarctic, are analysed to determine the long-term changes in NO2. An atmospheric photochemical box model and a radiative transfer model are used to improve the accuracy of determination of the vertical columns from the slant column measurements, and to deduce the amount of NOy from NO2. We find that the NO2 and NOy columns in midsummer have large inter-annual variability superimposed on a broad maximum in 2000, with little or no overall trend over the full time period. These changes are robust to a variety of alternative settings when determining vertical columns from slant columns or determining NOy from NO2. They may signify similar changes in speed of the Brewer-Dobson circulation but with opposite sign, i.e. a broad minimum around 2000. Multiple regressions show significant correlation with solar and quasi-biennial-oscillation indices, and weak correlation with El Nino, but no significant overall trend, corresponding to an increase in Brewer-Dobson circulation of 1.4+/-3.5%/decade. There remains an unexplained cycle of amplitude and period at least 15% and 17 years, with minimum speed in about 2000

Encouragement of Employment of the Handicapped

Six million Americans of employable age have a physical impairment which is sufficiently serious to hinder them in finding employment. Included among the handicapped are orthopedics, those having defective vision, hearing or speech, cardiacs, diabetics, epileptics, and others. Employment of handicapped persons is in the interest of society. Employed, the handicapped are tax-payers; unemployed, they are tax-spenders. If they are not given the employment which they desire the handicapped are forced to become a charge on society. To secure their employment, however, is a problem of great magnitude, requiring the cooperation of employers, employees, interested civic organizations and governmental agencies seeking rehabilitation of the handicapped

A History of Miranda and Why It Remains Vital Today

Custodial interrogations and how they are conducted in light of Miranda and its progeny are an integral part of the American criminal justice process and a necessary tool for criminal law enforcement, not merely a source of catchy phrases for today\u27s popular television shows, for a very simple reason: The warnings set the ground rules for custodial interrogations and ensure that the interrogator and suspect are on a level playing field. A review of the case law surrounding the Miranda decision reveals that Miranda is a case that has encapsulated the nation\u27s beliefs and, while subject to the ebbs and flows that come with an elastic and accommodating form of government, remains a vital component of the American criminal justice system

The Relationship between Personality Traits and Preferences for Instructional Methods

The purpose of this study is to develop an instrument that will measure student preference toward different classroom teaching methods; and to test whether significant differences exist between each of the Guilford-Zimmerman Temperament Survey scales for individuals preferring group-oriented and lecture-oriented instruction

The high-resolution versions of the model show an increase in eddy kinetic energy that peaks 2–3 yr after a positive anomaly in the SAM index. Previous work has shown that the instantaneous temperature response to the SAM is characterized by predominant cooling south of 45°S and warming to the north. At all resolutions the model captures this temperature response. This response is also evident in the coarse-resolution implementation of the model with no eddy mixing parameterization, showing that eddies do not play an important role in the instantaneous response. On the longer time scales, an intensification of the mesoscale eddy field occurs, which causes enhanced poleward heat flux and drives warming south of the oceanic Polar Front. This warming is of greater magnitude and occurs for a longer period than the initial cooling response. The results demonstrate that this warming is surface intensified and strongest in the mixed layer. Non-eddy-resolving models are unable to capture the delayed eddy-driven temperature response to the SAM. The authors therefore question the ability of coarse-resolution models, such as those commonly used in climate simulations, to accurately represent the full impacts of the SAM on the Southern Ocean

Halocarbons associated with Arctic sea ice

Short-lived halocarbons were measured in Arctic sea-ice brine, seawater and air above the Greenland and Norwegian seas (∼81°N, 2 to 5°E) in mid-summer, from a melting ice floe at the edge of the ice pack. In the ice floe, concentrations of C2H5I, 2-C3H7I and CH2Br2 showed significant enhancement in the sea ice brine, of average factors of 1.7, 1.4 and 2.5 times respectively, compared to the water underneath and after normalising to brine volume. Concentrations of mono-iodocarbons in air are the highest ever reported, and our calculations suggest increased fluxes of halocarbons to the atmosphere may result from their sea-ice enhancement. Some halocarbons were also measured in ice of the sub-Arctic in Hudson Bay (∼55°N, 77°W) in early spring, ice that was thicker, colder and less porous than the Arctic ice in summer, and in which the halocarbons were concentrated to values over 10 times larger than in the Arctic ice when normalised to brine volume. Concentrations in the Arctic ice were similar to those in Antarctic sea ice that was similarly warm and porous. As climate warms and Arctic sea ice becomes more like that of the Antarctic, our results lead us to expect the production of iodocarbons and so of reactive iodine gases to increase
