The 1964 Wellington Study of Beatlemania Revisited  [PDF]
A. J. W. Taylor
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.515190
Abstract: In June 1964, an Honours class in clinical psychology set out to objectify the major parameters of crowd and audience reaction to the Beatles’ during the group’s three-day visit to Wellington, New Zealand. Advance publicity had warned of the “mass-hysteria” to be expected at the sight, sound and lyrics of the four lads from Liverpool. Adolescents anticipated their arrival eagerly, while the authorities were disparaging and somewhat fearful of the breakdown in law and order that might occur. The findings were published in Britain in 1966, taken a little further in the United States in1968, and the original published once more in Britain in 1992 by special request to encourage more psychologists to undertake research off campus. When writers from those countries mentioned the study recently near the 50th anniversary of the Beatles’ visit, it seemed interesting to review the accretion of similar studies that might have occurred. Sadly, the outcome showed that psychologists had not taken mass-audience research any further. Hence it was thought appropriate to lift the Wellington study from obscurity, in the hope of inspiring the next generation to make amends.
One Fungus = One Name: DNA and fungal nomenclature twenty years after PCR
J.W. Taylor
IMA Fungus , 2011,
Abstract: Some fungi with pleomorphic life-cycles still bear two names despite more than 20 years of molecular phylogenetics that have shown how to merge the two systems of classification, the asexual “Deuteromycota” and the sexual “Eumycota”. Mycologists have begun to flout nomenclatorial regulations and use just one name for one fungus. The International Code of Botanical Nomenclature (ICBN) must change to accommodate current practice or become irrelevant. The fundamental difference in the size of fungi and plants had a role in the origin of dual nomenclature and continues to hinder the development of an ICBN that fully accommodates microscopic fungi. A nomenclatorial crisis also looms due to environmental sequencing, which suggests that most fungi will have to be named without a physical specimen. Mycology may need to break from the ICBN and create a MycoCode to account for fungi known only from environmental nucleic acid sequence (i.e. ENAS fungi).

The Alpha-Melanocyte Stimulating Hormone Induces Conversion of Effector T Cells into Treg Cells
Andrew W. Taylor,Darren J. Lee
Journal of Transplantation , 2011, DOI: 10.1155/2011/246856
Abstract: The neuropeptide alpha-melanocyte stimulating hormone (-MSH) has an important role in modulating immunity and homeostasis. The production of IFN- by effector T cells is suppressed by -MSH, while TGF- production is promoted in the same cells. Such -MSH-treated T cells have immune regulatory activity and suppress hypersensitivity, autoimmune diseases, and graft rejection. Previous characterizations of the -MSH-induced Treg cells showed that the cells are CD4
Convergence of weighted sums of independent random variables and an extension to Banach space-valued random variables
W. J. Padgett,R. L. Taylor
International Journal of Mathematics and Mathematical Sciences , 1979, DOI: 10.1155/s0161171279000272
Abstract: Let {Xk} be independent random variables with EXk=0 for all k and let {ank:n ¢ ‰ ¥1, ¢ € ‰k ¢ ‰ ¥1} be an array of real numbers. In this paper the almost sure convergence of Sn= ¢ ‘k=1nankXk, n=1,2, ¢ € |, to a constant is studied under various conditions on the weights {ank} and on the random variables {Xk} using martingale theory. In addition, the results are extended to weighted sums of random elements in Banach spaces which have Schauder bases. This extension provides a convergence theorem that applies to stochastic processes which may be considered as random elements in function spaces.
Parasites of South African wildlife. XVIII. Cooperia pigachei n. sp. (Nematoda : Cooperiidae) from the mountain reedbuck, Redunca fulvorufula (Afzelius, 1815)
J. Boomker,W.A. Taylor
Onderstepoort Journal of Veterinary Research , 2010, DOI: 10.4102/ojvr.v71i3.256
Abstract: A new species of Cooperia, for which the name Cooperia pigachei n. sp. is proposed, was recovered from a mountain reedbuck, Redunca fulvorufula, from the Sterkfontein Dam Nature Reserve, Free State Province, and is described and illustrated. It is close to Cooperia neitzi M nnig, 1932 and the South African race of Cooperia rotundispiculum in having more than 14 longitudinal cuticular ridges and in that the lateral cervical synlophe is of the closed type. The new species differs from all the other species of the genus in that the lateral branches of the dorsal ray are large and T-shaped. The spicules are robust, over 0.3 mm long and have large, curved shoes on their tips.
The Alpha-Melanocyte Stimulating Hormone Induces Conversion of Effector T Cells into Treg Cells

Journal of Transplantation , 2011, DOI: 10.1155/2011/246856
Abstract: The neuropeptide alpha-melanocyte stimulating hormone ( -MSH) has an important role in modulating immunity and homeostasis. The production of IFN- by effector T cells is suppressed by -MSH, while TGF- production is promoted in the same cells. Such -MSH-treated T cells have immune regulatory activity and suppress hypersensitivity, autoimmune diseases, and graft rejection. Previous characterizations of the -MSH-induced Treg cells showed that the cells are T cells expressing the same levels of CD25 as effector T cells. Therefore, we further analyzed the -MSH-induced Treg cells for expression of effector and regulatory T-cell markers. Also, we examined the potential for -MSH-induced Treg cells to be from the effector T-cell population. We found that the -MSH-induced Treg cells are T cells that share similar surface markers as effector T cells, except that they express on their surface LAP. Also, the -MSH treatment augments FoxP3 message in the effector T cells, and -MSH induction of regulatory activity was limited to the effector T-cell population. Therefore, -MSH converts effector T cells into Treg cells, which suppress immunity targeting specific antigens and tissues. 1. Introduction The melanocortin pathway is a highly conserved family of receptors and ligands that have important roles in regulating metabolism, pigmentation, and immunity [1–3]. The prototypic melanocortin, alpha-melanocyte stimulating factor ( -MSH), suppresses inflammation mediated by both innate and adaptive immunity. The neuropeptide -MSH inhibits NF-kB activation by blocking the intracellular signaling pathways initiated by TLR, scavenging, IL-1, and TNF receptors in macrophages, dendritic cells, and neutrophils through the melanocortin 1 receptor (MC1r) and the melanocortin 3 receptor (MC3r) [4–11]. In addition, -MSH induces MC1r expression, and transcription of proopiomelanocortin hormone in monocytes establishing a self-perpetuating immunosuppressive autocrine loop [12]. Because the serum levels of -MSH increase during the acute phase of inflammation [13] and the anti-inflammatory activity of -MSH has an antagonist relationship with proinflammatory mediators [2] suggests that -MSH has an important role in the resolution of inflammation and the maintenance of immune homeostasis. The analysis of the molecular mechanisms of ocular immune privilege demonstrates the importance of -MSH in preventing and suppressing inflammation within the healthy eye [14, 15]. Within the ocular microenvironment, the constitutively present -MSH has an important role in suppressing the activation of
Cirrus cloud-temperature interactions in the tropical tropopause layer: a case study

Atmospheric Chemistry and Physics (ACP) & Discussions (ACPD) , 2011,
Abstract: Thin cirrus clouds in the Tropical Tropopause Layer (TTL) have important ramifications for radiative transfer, stratospheric humidity, and vertical transport. A horizontally extensive and vertically thin cirrus cloud in the TTL was detected by the Cloud Aerosol LIDAR and Infrared Pathfinder Satellite Observations (CALIPSO) on 27–29 January 2009 in the Tropical Eastern Pacific region, distant from any regions of deep convection. These observations indicate that the cloud is close to 3000 km in length along the CALIPSO orbit track. Measurements over this three day period indicate that the cloud event extended over a region from approximately 15° S to 10° N and 90° W to 150° W and may be one of the most extensive cirrus events ever observed. Coincident temperature observations from the Constellation of Observing Satellites for Meteorology, Ionosphere, and Climate (COSMIC) suggest that the cloud formed in-situ as a result of a cold anomaly arising from a midlatitude intrusion. The event appears to last for up to 2 days and the temperature observations do not show any indication of the expected infrared heating. It is hypothesized that the cloud could be maintained by either nucleation of numerous small ice crystals that don't sediment or by multiple localized ice nucleation events driven by temperature variability at scales smaller than the overall cloud field, producing small ice-crystal sizes which have sufficiently long residence times (≈53 h) to maintain the cloud. It is possible that the residence times are augmented by vertical motion which could also act to offset the expected infrared heating. Further observations of similar events will be required in order to conclusively explain this curious cloud.
PSR J1518+4904: A Mildly Relativistic Binary Pulsar System
D. J. Nice,R. W. Sayer,J. H. Taylor
Physics , 1996, DOI: 10.1086/310178
Abstract: PSR J1518+4904 is a recently discovered 40.9~ms pulsar in an 8.6 day, moderately eccentric orbit. We have measured pulse arrival times for this pulsar over 1.4~yr at several radio frequencies, from which we have derived high precision rotational, astrometric, and orbital parameters. The upper limit for the period derivative of the pulsar, dP/dt<4x10^-20, gives a characteristic age of at least 1.6x10^10 yr, among the highest known. We find the orbit to be precessing at a rate of 0.0111+-0.0002 yr^-1, which yields a total system mass (pulsar plus companion) of 2.62+-0.07 M_solar according to general relativity. Further analysis of the orbital parameters yields a firm upper limit of 1.75 M_solar on the pulsar mass and constrains the companion mass to the range 0.9 to 2.7 M_solar. These masses, together with the sizable orbital eccentricity and other evidence, strongly suggest that the companion is a second neutron star.
