The importance of an awareness of the wider social context of any movement or individual is widely acknowledged, and does not need arguing. It constitutes a necessary criterion of the adequacy of any historical account. Yet there does not seem to have been any significant development in our critical appraisal of it among other criteria, and we still fail to produce agreed results. As a check on how things stand with other historians we may take, as a typical current survey, C. Behan McCullagh,Justifying Historical Descriptions. McCullagh makes a distinction that I have myself made before, but he makes it rather more elegantly. It lies in a contrast between the explanatory ‘scope’ and the ‘power’ of an historical account. An historical reconstruction may have a very wide scope, appearing to include all the data that is conventionally allowed to be relevant, and thus seem very persuasive. But the question remains to be asked, what power has it to exclude competing explanations?

Seasonal feeding and dietary overlap patterns between school mackerel (Scomberomorus queenslandicus) and spotted mackerel (S. munroi) in Queensland east-coast waters, Australia (16˚S to 28˚S), were examined from June 1992 to January 1995. School mackerel have a more diverse diet than spotted mackerel, with the diets of both species being dominated by pilchards, anchovies and herring. Dietary overlap between school and spotted mackerel appeared to be limited owing to temporal and spatial separation. The seasonal availability of certain prey items may play an important role in attracting mackerel into inshore waters where they become accessible to the commercial and recreational fisheries.

Snapper Chrysophrys auratus is a high-value food fish in Australia targeted by both commercial and recreational fisheries. Along the east coast of Australia, fisheries are managed under four state jurisdictions (Queensland, Qld; New South Wales, NSW; Victoria, Vic.; and Tasmania, Tas.), each applying different regulations, although it is thought that the fisheries target the same biological stock. An allozyme-based study in the mid-1990s identified a weak genetic disjunction north of Sydney (NSW) questioning the single-stock hypothesis. This study, focused on east-coast C. auratus, used nine microsatellite markers to assess the validity of the allozyme break and investigated whether genetic structure exists further south. Nine locations were sampled spanning four states and over 2000km, including sites north and south of the proposed allozyme disjunction. Analyses confirmed the presence of two distinct biological stocks along the east coast, with a region of genetic overlap around Eden in southern NSW, ~400km south of the allozyme disjunction. The findings indicate that C. auratus off Vic. and Tas. are distinct from those in Qld and NSW. For the purpose of stock assessment and management, the results indicate that Qld and NSW fisheries are targeting a single biological stock.A

This work summarises ichthyological research in the Tsitsikamma National Park (TNP) over the past 20 years, and an updated species check list of fishes has been compiled. A total of 202 species of fishes from 84 families has been recorded within the boundaries of the national park. All species which have been included were identified from visual transects, rotenone collections, estuarine surveys, ichthyoplankton surveys, mark/recapture studies and personal observations. The ichthyofauna is a diverse assemblage of chondrichthyans and teleosts, 75 (37.1) of which are components of commercial and recreational fisheries along the east coast. Surveys also indicate that the TNP provides refuge to all life history stages for 17 of the commercial and recreational teleost species. The need for more detailed collections of previously neglected teleost and chondrichthyan groups is recognised. The number of species and diversity demonstrates that the TNP appears not only to afford protection to exploited fish species, but also fulfills one of the basic requirements of Marine Protected Areas@that of conserving biodiversity (of fishes).

Purpose The purpose of this study was to investigate the relationship between oral language, literacy skills, age, and dialect density (DD) of African American children residing in two different geographical regions of the United States (East Coast and Midwest). Method Data were obtained from 64 African American school-age children between the ages of 7 and 12 years from two geographic regions. Children were assessed using a combination of standardized tests and narrative samples elicited from wordless picture books. Bivariate correlation and multiple regression analyses were used to determine relationships to and relative contributions of oral language, literacy, age, and geographic region to DD. Results Results of correlation analyses demonstrated a negative relationship between DD measures and children's literacy skills. Age-related findings between geographic regions indicated that the younger sample from the Midwest outscored the East Coast sample in reading comprehension and sentence complexity. Multiple regression analyses identified five variables (i.e., geographic region, age, mean length of utterance in morphemes, reading fluency, and phonological awareness) that accounted for 31% of the variance of children's DD—with geographic region emerging as the strongest predictor. Conclusions As in previous studies, the current study found an inverse relationship between DD and several literacy measures. Importantly, geographic region emerged as a strong predictor of DD. This finding highlights the need for a further study that goes beyond the mere description of relationships to comparing geographic regions and specifically focusing on racial composition, poverty, and school success measures through direct data collection.
