Ethnographies of the imagined, the imaginary and the critically real: Blackness, whiteness, the north of England and rugby league

Rugby league is part of the white, working-class (male) culture of the north of England, and is a sport that is used by its supporters to (re)produce both an imagined community of nostalgic northernness and an imaginary community of locally situated hegemonically masculine belonging. The invented traditions of its origins link the game to a white, working-class twentieth-century culture of mills, pits, terraced houses and pubs; a culture increasingly marginalised, reshaped and challenged in this century. In this paper we use two medium-term, ethnographic research projects on rugby league (one from Spracklen; the other an on-going project by Timmins) to explore northernness, blackness, whiteness and our own roles in the ethnographies as 'black' and 'white' researchers researching 'race' and identity in a community that remains (but not exclusively) a place for a working-class whiteness to be articulated. We argue that our own histories and identities are pivotal in how we are accepted as legitimate ethnographers and insiders, but those histories and identities also posea critically real challenge to us and to those in the community of rugby league with whom we interact. © 2010 Taylor & Francis

Derivation of transformation formulas between geocentric and geodetic coordinates for nonzero altitudes

Four formulas, for the nonzero altitude transformation from geodetic coordinates (geodetic latitude and altitude) to geocentric coordinates (geocentric latitude and geocentric distance) and vice versa, are derived. The set of four formulas is expressed in each of the three useful forms: series expansion in powers of the earth's flattening; series expansion in powers of the earth's eccentricity; and Fourier series expansion in terms of the geodetic latitude or the geocentric latitude. The error incurred in these series expansions is of the order of one part in 3 x 10 to the 7th power

The Mayflies (Ephemeroptera) of Tennessee, With a Review of the Possibly Threatened Species Occurring Within the State

One hundred and forty-three species of mayflies are reported from the state of Tennessee. Sixteen species (Ameletus cryptostimulus, Choroterpes basalis, Baetis virile, Ephemera blanda, E. simulans, Ephemerella berneri, Heterocloeon curiosum, H. petersi, Labiobaetis ephippiatus, Leptophlebia bradleyi, Macdunnoa brunnea, Paraleptophlebia assimilis, P. debilis, P. mollis, Rhithrogenia pellucida and Siphlonurus mirus) are reported for the first time. Rare and vulnerable species occurring in the state are also discussed. This represents the first comprehensive statewide list of mayflies for Tennessee

Effects of various experimental parameters on errors in triangulation solution of elongated object in space

The effects of various experimental parameters on the displacement errors in the triangulation solution of an elongated object in space due to pointing uncertainties in the lines of sight have been determined. These parameters were the number and location of observation stations, the object's location in latitude and longitude, and the spacing of the input data points on the azimuth-elevation image traces. The displacement errors due to uncertainties in the coordinates of a moving station have been determined as functions of the number and location of the stations. The effects of incorporating the input data from additional cameras at one of the stations were also investigated

Thermoluminescent aerosol analysis

A method for detecting and measuring trace amounts of aerosols when reacted with ozone in a gaseous environment was examined. A sample aerosol was exposed to a fixed ozone concentration for a fixed period of time, and a fluorescer was added to the exposed sample. The sample was heated in a 30 C/minute linear temperature profile to 200 C. The trace peak was measured and recorded as a function of the test aerosol and the recorded thermoluminescence trace peak of the fluorescer is specific to the aerosol being tested
