As part of the programme of study of the geology of the western approaches initiated at Bristol by Prof. W. F. Whittard (Whittard, 1962) information has been accumulated concerning the distribution and nature of the metamorphic rocks exposed in a series of inliers between Start Point in the east and Dodman Point in the west.Early dredgings in this area were described by Worth (1908). Six core samples and two dredgings of metamorphic rocks are listed by Hill & King (1953). Mica schist in situ is recorded by Holme (1953). Various cruises in R.V. ‘Sarsia’ from 1957 onwards have yielded seventeen cores and further dredged samples. Additional material, collected from the exposed parts of the Eddystone reefs or obtained by diving at critical localities, has become available through the kindness of members of the staff of the Marine Biological Laboratory at Plymouth.Sixteen cores and eight dredged samples serve to demarcate an area of schistose rocks, extending some 24 miles from east to west and 7 miles in maximum width from north to south, off the southernmost part of Devon (Fig. 1). These rocks, with an exception to be noted, compare closely with those exposed on land, between Bolt Tail and Start Point, south of a well defined east-west boundary (Ussher, 1904; Tilley, 1923). There are examples of quartz-muscovite-chlorite schists precisely like the Start Mica-schists and Bolt Mica-schists described by Tilley. Albite porphyroblasts, in a rock dredged near East Rutts (Fig. I, 1262) which is transitional to Tilley's ‘schists of composite origin’, show well the contorted swarms of carbonaceous inclusions which he describes (1923, p. 180).

AbstractThis note records the presence of Eocene limestones in situ on the bed of the English Channel along an east-west line to the west of the island of Jersey. The microfauna of samples of these limestones is compared with those of some other beds of similar age. There are comments on the relevance of the above discoveries to the structural history of the area.

The studies reported here focus on similarities and dissimilarities between the terminal value hierarchies ( Rokeach, 1973 ) ascribed to different groups ( Schwartz & Struch, 1990 ). In Study 1, n = 65 East Germans and n = 110 West Germans mutually assess the respective ingroup and outgroup. In this intra-German comparison the West Germans, with a mean intraindividual correlation of rho = 0.609, perceive a significantly greater East-West similarity between the group-related value hierarchies than the East Germans, with a mean rho = 0.400. Study 2 gives East German subjects either a Swiss (n = 58) or Polish (n = 59) frame of reference in the comparison between the categories German and East German. Whereas the Swiss frame of reference should arouse a need for uniqueness, the Polish frame of reference should arouse a need for similarity. In accordance with expectations, the Swiss frame of reference significantly reduces the correlative similarity between German and East German from a mean rho = 0.703 in a control group (n = 59) to a mean rho = 0.518 in the experimental group. Contrary to expectations, the Polish frame of reference does not lead to an increase in perceived similarity (mean rho = 0.712).

Fungi have an important role in nutrient cycling in most ecosystems on Earth, yet their ecology and functionality in deep continental subsurface remain unknown. Here, we report the first observations of active fungal colonization of mica schist in the deep continental biosphere and the ability of deep subsurface fungi to attach to rock surfaces under in situ conditions in groundwater at 500 and 967 m depth in Precambrian bedrock. We present an in situ subsurface biofilm trap, designed to reveal sessile microbial communities on rock surface in deep continental groundwater, using Outokumpu Deep Drill Hole, in eastern Finland, as a test site. The observed fungal phyla in Outokumpu subsurface were Basidiomycota, Ascomycota, and Mortierellomycota. In addition, significant proportion of the community represented unclassified Fungi. Sessile fungal communities on mica schist surfaces differed from the planktic fungal communities. The main bacterial phyla were Firmicutes, Proteobacteria, and Actinobacteriota. Biofilm formation on rock surfaces is a slow process and our results indicate that fungal and bacterial communities dominate the early surface attachment process, when pristine mineral surfaces are exposed to deep subsurface ecosystems. Various fungi showed statistically significant cross-kingdom correlation with both thiosulfate and sulfate reducing bacteria, e.g., SRB2 with fungi Debaryomyces hansenii.

Abstract A dual-station high-frequency Wellen Radar (WERA), transmitting at 16.045 MHz, was deployed along the west Florida shelf in phased array mode during the summer of 2003. A 33-day, continuous time series of radial and vector surface current fields was acquired starting on 23 August ending 25 September 2003. Over a 30-min sample interval, WERA mapped coastal ocean currents over an ≈40 km × 80 km footprint with a 1.2-km horizontal resolution. A total of 1628 snapshots of the vector surface currents was acquired, with only 70 samples (4.3%) missing from the vector time series. Comparisons to subsurface measurements from two moored acoustic Doppler current profilers revealed RMS differences of 1 to 5 cm s−1 for both radial and Cartesian current components. Regression analyses indicated slopes close to unity with small biases between surface and subsurface measurements at 4-m depth in the east–west (u) and north–south (υ) components, respectively. Vector correlation coefficients were 0.9 with complex phases of −3° and 5° at EC4 (20-m isobath) and NA2 (25-m isobath) moorings, respectively. Complex surface circulation patterns were observed that included tidal and wind-driven currents over the west Florida shelf. Tidal current amplitudes were 4 to 5 cm s−1 for the diurnal and semidiurnal constituents. Vertical structure of these tidal currents indicated that the semidiurnal components were predominantly barotropic whereas diurnal tidal currents had more of a baroclinic component. Tidal currents were removed from the observed current time series and were compared to the 10-m adjusted winds at a surface mooring. Based on these time series comparisons, regression slopes were 0.02 to 0.03 in the east–west and north–south directions, respectively. During Tropical Storm Henri’s passage on 5 September 2003, cyclonically rotating surface winds forced surface velocities of more than 35 cm s−1 as Henri made landfall north of Tampa Bay, Florida. These results suggest that the WERA measured the surface velocity well under weak to tropical storm wind conditions.

Abstract That English has spread in Asia is well-known, but this critical reflection, and the five contributions and book review that we hereby introduce, contribute to rectifying the relative absence in the sociology of language literature of studies approaching language ideologies and practices in specific Asian contexts from local perspectives. We are not alone; our inspections of journal archives show that scholars are increasingly responding to this relative absence in recent years. What this special issue offers is further diversity of both authors and cases, and moreover this special issue draws attention to the immutable, binary structure underlying the various globally-circulating discourses of the East and the West as part of investigating how socially constructed East-West binaries interact with language ideologies about English and other languages. It shifts the attention from fixity – East versus West – to diversity, extending East to Easts and West to Wests as our contributors identify and examine multiple, endogenous “imaginative geograph[ies]” (from Arif Dirlik’s [1996] “Chinese history and the question of Orientalism”, History and Theory 35(4): 97) constructed through various Orientalist ideologies. It founds this approach on a combination of the theory of recursive language ideologies and critical Orientalism scholarship. This is generative of new and useful sociolinguistic analyses. Having laid out this theoretical extension, this editorial then provides an overview of the issue’s contributions, which examine how socially constructed East-West binaries are interacting with language ideologies about English and other languages on sub-national scales in various Asian contexts including in Korea, China, Japan, Tajikistan and Pakistan.

Gain Access

Ever since the discovery of China by Western nations the West has continually tried to gain access to China, and sometime even to understand her. Conversely, many Eastern nations who came within China's reach have preferred to keep her at arms length. This dichotomy continues today, although the East/West division is less clear. The People's Republic of China's sheer geographical size, its location in the heart of Asia, its huge population and thus its potential as an economic and miitary superpower instils fear in many. Will the PRC become a ‘responsible power’, an irresponsible hegemon, or collapse into political disorder and chaos? In anticipation of the coming changes in the PRC, the foreign policy of those nations concerned with the PRC has oscillated between engagement and containment of China.

The Temple

On the east slope of Lower Gypsades hill, about 100 metres west of the Temple Tomb, a chamber tomb came to light in August 1958, when a cutting for a new water pipe was driven through the area (A in Plate 9 a). In the course of this operation, part of a plain larnax (iii) was sliced off, and much earth removed from the west end of the collapsed chamber: at no point, however, had the municipal workmen penetrated to the tomb floor.The chamber was approached by a sloping dromos (Plate 9 a: length 2·80 metres; max. width 1 metre), roughly cut into the natural kouskouras rock: its walls were approximately perpendicular. Although the gradient varied a good deal, there was no suggestion of a stairway.The blocking wall was found in good condition. Of especial interest were the numerous fragments of larnakes that had been built into its fabric: some of them could be recognized as belonging to each of the three fragmentary larnakes (i, ii, v) whose scattered pieces were found below and around the two undisturbed burials in the chamber (iii, iv). We may thus distinguish two periods in the history of the tomb: larnakes i, ii, and v were evidently smashed up in order to make room for iv and iii, which must have been deposited in that order. The debris of v was found under iv, with a few adult bones in its wreckage. Part of i lay on the floor near the south-west corner, where two plain vases (2, 3) were found in situ, hence, also, came most of the fragments of the fine L.M. IIIA 2 stirrup vase (1), although its other pieces were scattered all over the floor of the tomb. This small group of offerings may belong to the disturbed adult skeleton, whose skull lay up against the lower edge of iii. Curiously, some fragments of i and ii were also found above the broken lid of iv (Plate 9 b): perhaps the lid of the later larnax was accidentally smashed at the time of the funeral, in which case the debris from earlier burials could have been piled up above it, as a rough and ready means of protection.

Symbiont Acquisition

AbstractSymbiotic associations between animals and microorganisms are widespread and have a profound impact on the ecology, behaviour, physiology, and evolution of the host. Research on deep-sea mussels of the genus Bathymodiolus has revealed how chemosynthetic symbionts sustain their host with energy, allowing them to survive in the nutrient-poor environment of the deep ocean. However, to date, we know little about the initial symbiont colonization and how this is integrated into the early development of these mussels. Here we analysed the early developmental life stages of B. azoricus, “B”. childressi and B. puteoserpentis and the changes that occur once the mussels are colonized by symbionts. We combined synchrotron-radiation based μCT, correlative light and electron microscopy and fluorescence in situ hybridization to show that the symbiont colonization started when the animal settled on the sea floor and began its metamorphosis into an adult animal. Furthermore, we observed aposymbiotic life stages with a fully developed digestive system which was streamlined after symbiont acquisition. This suggests that bathymodiolin mussels change their nutritional strategy from initial filter-feeding to relying on the energy provided by their symbionts. After ~35 years of research on bathymodiolin mussels, we are beginning to answer fundamental ecological questions concerning their life cycle and the establishment of symbiosis.
