The over-production of US sports and the new International Division of Cultural Labor

This article focuses on how US professional sports utilize the New International Division of Cultural Labor to supplement an overly costly local labor pool and over-supplied local market. We argue that while the classic problem of over-production is slowly eroding the sealed-off nature of US culture, the forces of its hyper-protectionist capitalism continue to characterize sports, precluding equal exchange.

Electropalatographic assessment of tongue-to-palate contacts exhibited in dysarthria following traumatic brain injury: Spatial characteristics

Consonant imprecision has been reported to be a common feature of the dysarthric speech disturbances exhibited by individuals who have sustained a traumatic brain injury (TBI). Inaccurate tongue placements against the hard palate during consonant articulation may be one factor underlying the imprecision. To investigate this hypothesis, electropalatography (EPG) was used to assess the spatial characteristics of the tongue-to-palate contacts exhibited by three males (aged 23-29 years) with dysarthria following severe TBI. Five nonneurologically impaired adults served as control subjects. Twelve single-syllable words of CV or CVC construction (where initial C = /t, d, S, z, k, g/, V=/i, a/) were read aloud three times by each subject while wearing an EPG palate. Spatial characteristics were analyzed in terms of the location, pattern, and amount of tongue-to-palate contact at the frame of maximum contact during production of each consonant. The results revealed that for the majority of consonants, the patterns and locations of contacts exhibited by the TBI subjects were consistent with the contacts generated by the group of control subjects. One notable exception was one subject's production of the alveolar fricatives in which complete closure across the palate was demonstrated, rather than the characteristic groove configuration. Major discrepancies were also noted in relation to the amount of tongue-to-palate contact exhibited, with two TBI subjects consistently demonstrating increased contacts compared to the control subjects. The implications of these findings for the development of treatment programs for dysarthric speech disorders subsequent to TBI are highlighted.

Production of proteinases by psychrotrophic bacteria in raw milk stored at low temperature

Raw milk samples from two different sources were stored at 2degreesC, 4degreesC and 7degreesC for 10 days and the growth of psychrotrophic bacteria, production of proteinase and proteolysis in the milks were measured during storage. Peptide analyses by the fluorescamine method and RP-HPLC were used in determination of proteolysis and proteinase activity. The average times taken for the psychrotroph counts to reach 10(7) cfu/mL at 2degreesC, 4degreesC and 7degreesC were approximately 9, 7 and 4 days, although there was considerable variation in growth rates in the different milks. There was little correlation between psychrotroph counts and either proteolysis or proteinase activity levels. At 2degreesC, no milk stored showed significant proteolysis by the fluorescamine method after 10 days' storage, but significant proteinase activity could be measured in some of these milks at 8 and 10 days. RP-HPLC analysis was a more sensitive means of detecting peptides than the fluorescamine method.

Mitigated directness in Honglou meng: directive speech acts and politeness in eighteenth century Chinese

This paper is situated within a theoretical discussion that asserts a positive correlation between indirectness and politeness, and uses these claims as a springboard for an examination of polite ways of issuing directives in eighteenth century Chinese. On the basis of an analysis of directive speech acts from dialogue in the novel Honglou meng, it argues that the concept of indirectness, as it applies to the illocutionary transparency of individual speech acts, has no particular value in the culture and language of eighteenth century Chinese men. It is found that other linguistic devices such as particles, the reduplication of verbs, terms of address, and the presence and sequencing of supportive moves are far more significant to the communication of politeness. The findings suggest a need to rethink current theoretical positions on this subject and move beyond the analysis of individual speech acts to examine the role discourse structure and management play in the enactment of politeness.

Structural variations and formation constants of first-row transition metal complexes of biologically active aroylhydrazones

Iron chelators of the 2-pyridinecarbaldehyde isonicotinoylhydrazone (HPCIH) class show high potential for the treatment of iron overload diseases. In the present study, selected first-row transition metal (from Mn to Zn) complexes with HPCIH and 2-pyridinecarbaldehyde (4'-aminobenzoyl)hydrazone (HPCAH) were synthesised and characterised. Crystallography reveals that HPCAH exclusively forms bis complexes with divalent transition metals, with each ligand coordinating meridionally through its pyridine-N, imine-N and carbonyl-O atoms, forming distorted octahedral cis-MN4O2 complexes. Complexes of HPCIH were more varied and unpredictable, with metal/ligand ratios of 1:1, 1:2, 2:2 and 3:2 obtained with different metal ions. The isonicotinoyl ring N-atom in HPCIH was found to be an effective ligand, and this resulted in the varied metal/ligand ratios observed. The formation constants of divalent metal complexes with HPCIH were determined by potentiometric titrations and the values obtained were consistent with similar tridentate ligands and with the Irving-Williams order.
