Sportainment: Changing the Pace of Limited-overs Cricket in South Africa

This study addresses the need to deepen the understanding of sports marketing in an emerging market context. The in-depth case study of Standard Bank Pro20 Cricket explores the strategy, execution and results of the successful launch of a new cricket format in South Africa. As such, it contributes to the theory and practice of sport marketing, especially sport event sponsorship. Schwartz and Hunter (2008) highlight the “lucrative” (p. 251) nature of tournaments and championships sponsorships, given the opportunity for media and advertising exposure related to the event. This study documents the effective use of a partnership approach to sponsorship (Meenaghan, 2002) and the creative use of multiple sponsorship activations to achieve the sponsorship’s objectives

Frequency distribution of conception dates in a white-tailed deer herd

Conception dates of white-tailed deer, Odocoi/eus virginia1111s (Zinunennann, 1780) were estimated for the breeding periods of 1974 - 76 and 1984 using fall and winter- spring fetal data. Conception dates estimated from data collected in the fall were biased. This bias resulted in an earlier mean conception date than that based on information which included data from later breeding females. Mean breeding dates differed significantly between female age classes due to delayed conception in fawns which also resulted in a skewed frequency distribution of conception dates. The frequency distribution of conception dates was leptokurtotic, suggesting that the distribution is constrnincd in time by some factor(s). Conception date estimates did not differ by habitat type but were influenced significantly by period of data collection. Mean breeding date for deer on Lhe Savannah River Site, corrected for age class sampling bias, is 20 November± 27 days (adults plus fawns) and 13 November± 15 days (only adults)

Genetic Structure of Mosquitofish Populations in the Altamaha and Ogeechee Drainages of Georgia: Reporting an Undescribed Form in the Ocmulgee River

An electrophoretic survey of genetic variation in mosquitofish populations of the Altamaha and Ogeechee drainages in Georgia revealed significant divergence (fs,=O.270) among populations within the Altamaha. Cluster analysis showed two lineages: one formed by populations from the Ogeechee drainage and the eastern and central Altamaha branches and another consisting of populations from the Ocmulgee River, the westernmost branch of the Altamaha drainage. These lineages may represent two independent forms. Average modified Rogers’ genetic distance was 0.25% between the two groups. The O_cmulgee lineage had significantly higher multilocus heterozygosity (H=0.206) than the other one (I-/=0.120). The high heterozygosity in the Ocmulgee lineage is consistent with the hypothesis that it originated by hybridization. Populations in the Altamaha and Ogeechee exhibit spatial patterns of genetic characteristics similar to those previously described for populations in other drainages

Assessment of Fawn Breeding in a South Carolina Deer Herd

Annual variation in breeding success among female white-tailed deer (Odocoileus virginianus) fawns on the Savannah River Plant (1967 to 1985) was determined from direct counts of pregnancy in spring-collected fawn females and evidence of lactation and measurements of udder thickness in fall-harvested 1. 5-yearolds. Percent lactation in 1.5-year-old females collected during September and October gave the best estimate of fawn breeding in the previous year. The overall mean fawn breeding estimate from September and October was 41 % , and the yearly variation in fawn breeding was significant. An estimate of the average yearly contribution to recruitment was 43 fetuses per 100 fawn females

Ground-layer wavefront reconstruction from multiple natural guide stars

Observational tests of ground layer wavefront recovery have been made in open loop using a constellation of four natural guide stars at the 1.55 m Kuiper telescope in Arizona. Such tests explore the effectiveness of wide-field seeing improvement by correction of low-lying atmospheric turbulence with ground-layer adaptive optics (GLAO). The wavefronts from the four stars were measured simultaneously on a Shack-Hartmann wavefront sensor (WFS). The WFS placed a 5 x 5 array of square subapertures across the pupil of the telescope, allowing for wavefront reconstruction up to the fifth radial Zernike order. We find that the wavefront aberration in each star can be roughly halved by subtracting the average of the wavefronts from the other three stars. Wavefront correction on this basis leads to a reduction in width of the seeing-limited stellar image by up to a factor of 3, with image sharpening effective from the visible to near infrared wavelengths over a field of at least 2 arc minutes. We conclude that GLAO correction will be a valuable tool that can increase resolution and spectrographic throughput across a broad range of seeing-limited observations.Comment: 25 pages, 8 figures, to be published in Astrophys.

Kinematics of the ion tail of comet P/Swift-Tuttle

We have obtained long-slit high resolution spectra of the H_2O^+ 6199 Å complex in the near tail of comet P/Swift-Tuttle. The observations were made using the Hamilton echelle spectrometer fed by the Lick Observatory 0.6 m coude auxiliary telescope. For most of our observations, the spectral slit was aligned along the Sun-tail axis and the cometary nucleus was placed at one end of the slit, giving us spectra having the spatial and spectral resolution needed to measure the radial velocity and velocity dispersion continuously down the cometary tail out to a distance of 4 x 10^5 km. The radial velocities confirm the earlier more restricted observations by Rauer & Jockers [Icarus, 102, 117 (1993)] and by Wyckoff & Lindholm (1994) showing that the tail motions are indeed bulk flows in the antisolar direction. Out to 3 x 10^5 km in the tail typical bulk flows are at a speed of -30 km s^(-1). The velocity dispersion, (σ_r), of the H_2O^+ lines follows a pattern that is quite systematic; σ_r is smallest near the cometary nucleus, and steadily increases down the tail. The highest velocity dispersions are found ahead of the nucleus and off the tail axis. These velocity dispersions are equivalent to ion temperatures ranging from 10^5 to 10^6 K. We note a clear anticorrelation between the H_2O^+ line intensities (related to the ion density) and the bulk flow and dispersion velocities; direct mass loading of the solar wind by the observed water ions may be responsible. We discuss several approximate equipartition methods used to infer local magnetic fields induced by the interaction of the cometary ions with the solar wind particle/field stream. Typical fields derived are near 50 nT. The measured tailward accelerations are consistent with this order of magnitude B field
