Supplicating, naming, offering: Tawassul in West Java
Authors: Millie Julian 
Published: December 2007

AbstractThe tawassul is a ritual invocation popularly used in West Java at grave visits and in other Islamic observances. In simple terms, it consists of two acts; the naming of figures who are considered as mediators (wasilah) between a supplicant and Allah, and the making of an offering for the benefit of the mediator. Participants in tawassul hold contrasting understandings of what is achieved by performing it. Furthermore, the invocation is easily adapted for diverse settings while retaining its basic syntax. This multivocality and flexibility provide keys to understanding the popularity of the tawassul as a religious observance for Sundanese Muslims.
‘Hinduism’ and ‘Taoism’ in Singapore: Seeing points of convergence
Authors: Sinha Vineeta 
Published: December 2007

AbstractThe paper begins by documenting the meanings the labels ‘Hinduism’ and ‘Taoism’ carry locally and highlights the complexities and ambiguities in discussions that invoke them. I then present data which demonstrate significant points of convergence between these two religious traditions, viewed as ‘ethnic religions’ and asserted to be ‘different’ in the Singaporean context. The turn to the organisational domain is instructive in revealing how ‘Hindu’ and ‘Taoist’ institutions have talked about their respective religions in the public sphere. This focus allows me to highlight overlaps in the two sets of discourses, to ask why these affinities should exist and to reflect on the sociological implications of such a phenomenon.
Power and factional struggles in post-independence Burmese governments
Authors: Yin Hlaing Kyaw 
Published: December 2007

AbstractThis article explains the ways in which power and factional struggles broke out and ended in post-independence Burma. In so doing, it argues that the key to a proper understanding of the situation resides in a careful examination of the internal power structure of an existing government. On the basis of the historical analysis as explicated in the article, it may be surmised that the existence of a hegemon that is able to mediate between factions while not relying on them in turn for his own influence and authority, yields a good possibility of a stable government. Conversely, the absence of such a hegemon results in an unstable government. Stability, however, being simply a condition, does not naturally predispose a hegemon towards virtuous governance.
Reference systems of maps and geographic information systems of Antarctica
Authors: Sievers Jörn , Bennat Heinz 
Published: December 2007

The necessity for uniform reference systems for conventional maps (analogue) and geographic information systems (digital) is discussed. It is recommended that the following scales and projections are used for Antarctic maps: general maps at scales smaller than 1:1 000 000 should use a stereographic projection. Maps up to a scale of 1:1 000 000 should be compiled according to the specifications of the International Map of the World (IMW) 1:1 000 000. Ellipsoids are used as reference surfaces for the various map projections. Differences of the ellipsoidal parameters of the WGS72 and WGS84 systems have to be considered if accuracies better than 10 m are required. Geographic information systems may store data in vector or raster format and in geographic or in geodetic coordinates. For a raster format which is referred to the geographic (spheroidal) grid the term of ‘geographic raster’ is introduced, in contrast to the ‘geodetic raster’ which is referred to a plane cartesian coordinate system. The Institut für Angewandte Geodäsie (IfAG) is establishing the ‘Geocoded Information System Antarctica’ (GIA) using digital satellite image recordings. Internal storage of data in the GIA is in the form of the geodetic raster (and not by spheroidal coordinates). For the scale range 1:250 000 to 1:1 000 000 the size of the raster element is 60 m × 60 m. For smaller scales, satellite image data of a raster width of 240 m × 240 m are preferred.‘All cartographers' trouble began with the abolition of the flat-Earth theory ’
Antarctic Science—5th BIG year!
Authors: Walton D. W. H. , Thomson M. R. A. , Mobbs S. D. 
Published: December 2007

As Antarctic Science enters its fifth year, it is time to assess progress and review the opportunities for Antarctic research in the coming years. The journal appears to have filled a useful niche, established arange of regular (and irregular!) contributors, and is taken by the majority of major polar libraries world-wide. Quality of production has improved with new equipment but rate of publication has fallen with increasing numbers of acceptable contributions. Cross-disciplinary papers have been few — but perhaps that is because few Antarctic scientists have undertaken the challenge of cross-disciplinary studies? Glaciology and most aspects of atmospheric sciences are still under-represented.Our first special issue on the palynology of James Ross Island has been well received and a second, on a Southern Ocean cephalopod symposium, is planned for 1994. These special issues are a bonus to subcribers who get the extra pages free. The editors are keen to receive proposals for other special issues with offers of appropriate funding.
Science vs the Environment
Authors: Howard-Williams Clive 
Published: December 2007

The Environmental Protocol to the Antarctic Treaty is rapidly approaching ratification, and nations which have now signed it see the Protocol as a signal for considerable future debate, if not scrutiny. Everyone has begun to implement, at least in spirit, many of its requirements which are now beginning to have an effect on science on the continent. This is currently evident in at least four different ways:
a reallocation of funding from pure science, to ï¿½appliedï¿½ science relating to human impacts,an increase in funding to allow for studies of human impact and the meeting of Protocol obligations,a reassessment by the science community on what can be done with minimal impact, and an imposition on the science community of rules and codes which will restrict many types of scientific work that have been carried out in the past, and will force modifications of future work.
Because all science on the continent (as opposed too remote sensing from space) will have an impact
there will have to be tradeoffs between the benefit to science and the impact of doing the work. We can only evaluate impacts on those areas of science that we know about at present. The problem is that there will be future, presently unknown areas of science that may be compromised by operations currently considered ï¿½safeï¿½. Who knows, for instance, what viruses we are inadvertently spreading and what the importance of these will be in future studies? At present the effects of these organisms are difficult to measure but studies on the role of viruses in natural ecosystems are increasing as technology expands.
The stratigraphy and geochronology of Adelaide Island
Authors: Griffiths Chris J. , Oglethorpe Richard D. J. 
Published: December 2007

The Mesozoic-Cenozoic volcanic arc of the Antarctic Peninsula is represented on Adelaide Island by a sedimentary and volcanic succession intruded by plutons. 40Ar-39 Ar step-heating age spectra have been obtained from volcanic rocks and hornblende separates from sedimentary clasts of plutonic origin. These spectra show evidence for some argon loss, but, in general, have plateau ages which are consistent with the mapped stratigraphy and with other geochronological controls, suggesting that they approximate to original ages. As a result the following events in the evolution of Adelaide Island can be recognized:1) mostly marine Mesozoic sedimentation, 2) Early Cretaceous (c. 141 Ma) plutonism (recorded in clasts from conglomerates), 3) Cretaceous volcanism, 4) Late Cretaceous (possibly Tertiary) sedimentation, 5) Early Tertiary volcanism, which was acidic in eastern outcrops and intermediate elsewhere, and 6) Eocene intermediate volcanism and deposition of arc-derived conglomerates. Volcanism was possibly coeval with known Palaeocene-Eocene plutonic activity on Adelaide Island (part of the Antarctic Peninsula Batholith) and with volcanism of similar age in northern Alexander Island and the South Shetland Islands. The volcanism on Adelaide Island and the South Shetland Islands, at least, was associated with a westward migration of the Antarctic Peninsula arc.

Nigrospora sphaerica Causing Leaf Spot and Twig and Shoot Blight on Blueberry: A New Host of the Pathogen
Authors: Wright E. R. , Folgado M. , Rivera M. C. , Crelier A. , Vasquez P. , Lopez S. E. 
Published: December 2007

Blueberries (Vaccinium corymbosum) have recently become an important alternative crop in different ecological regions of Argentina. In surveys, a new disease characterized by leaf spots and twig and shoot blight has been observed on plants cultivated in Arrecifes, Mercedes, and San Pedro (provinces of Buenos Aires) and Concordia (province of Entre Ríos) since July 2004. Spots initially appear brown, circular, 1 to 2 mm in diameter, and irregularly distributed on the leaves and they eventually coalesce. Fruiting twig and shoot blight developed from the tips toward the base. Affected plants of cvs. O'Neal and Reveille were distributed randomly in the field and with a low incidence (average of 2%). The objective of this work was to identify the causal agent of this disease. Symptomatic plant material was surface disinfested with 0.2% NaOCl for 1 min and 70% ethanol for 1 min, washed once with sterile distilled water, blotted dry with paper towels, and plated on potato dextrose agar. Colonies were initially white, becoming light to dark gray with the onset of sporulation with black, sphaerical to subsphaerical conidia that measured 14 to 19 × 12 to 16 μm. These characteristics agree with published descriptions of Nigrospora sphaerica (Sacc.) Mason (1,4). To evaluate pathogenicity, all leaves, petioles, and stems of seven healthy potted plants of cv. O'Neal were punctured with flamed needles and sprayed with a suspension of 1 × 108 spores of the fungus per milliliter of sterile distilled water. Another seven nonwounded plants were sprayed with the spore suspension. Seven plants similarly injured and seven nonwounded plants were sprayed with sterile distilled water and served as controls. Each plant was covered with a water-sprayed polyethylene bag and maintained in a controlled environment chamber at 20°C with a 12-h photoperiod. The bags were removed after 3 days. All wounded inoculated plants began to show disease symptoms similar to those observed in the field 20 days after inoculation. Controls and nonwounded inoculated plants remained symptomless. The pathogen was reisolated from diseased tissues fulfilling Koch's postulates. N. sphaerica is a well-known saprophyte on many plant species but has been mentioned as pathogen on many hosts (2,3). To our knowledge, this is the first reference of N. sphaerica as a wound pathogen of blueberry. In the field, the fungus would have gained access to the plant through wounds caused by insects or frost after a long-term wetness duration. References: (1) M. B. Ellis. Dematiaceous Hyphomycetes.

Occurrence of Sclerotinia Stem Rot on Canola Caused by Sclerotinia minor in Argentina
Authors: Gaetán S. A. , Madia M. 
Published: December 2007

Canola (Brassica napus) is a minor rotation crop grown since the 1990s in Buenos Aires Province, Argentina because of its potential as a source of biodiesel. During the spring of 2006, typical signs and symptoms of Sclerotinia stem rot were observed on canola plants (cv. Master) in one production field at 9 de Julio locality in Buenos Airs Province. Affected plants were distributed in patches throughout the rows at flowering and podfilling stages resulting in approximately 7 to 11% plant loss. Initial symptoms consisted of yellowing of mature leaves, decaying, and necrosis of lower stems. Ultimately, crowns and lower stems rotted, stems bleached, pods remained unfilled, and entire plants collapsed. White mycelium and numerous small sclerotia appeared on crown tissues. Samples of 20 infected plants were randomly collected in one production field, and 5- to 10-mm pieces of symptomatic tissues were cultured on potato dextrose agar (PDA) for 7 to 8 days after disinfestation with 2% sodium hypochlorite. Four colonies isolated from symptomatic tissues were identified as Sclerotinia minor Jagger (3) on the basis of white, fluffy mycelium containing black, irregularly shaped sclerotia (≤2 mm in diameter) abundantly scattered over the cultured surface. Crown inoculations were performed for two isolates by placing a plug taken from an actively growing culture of S. minor into wounds made on 6-week-old canola plants (cvs. Eclipse, Master, and Mistral). Control plants received plugs of sterile PDA. Inoculated and control plants were enclosed in plastic bags for 72 h. Symptoms similar to those in the affected fields were evident within 2 weeks of postinoculation on inoculated plants, whereas control plants remained healthy. The pathogen was successfully recovered from infected tissues fulfilling Koch's postulates. The experiment was repeated with similar results. Sclerotinia stem rot caused by S. sclerotiorum (Lib.) de Bary was previously reported on canola in Argentina in 2005 (2), and S. minor is a pathogen of B. napus in the United States (1). To our knowledge, this is the first report of Sclerotinia stem rot of canola incited by S. minor in Argentina. References: (1) D. F. Farr et al.

First Report of Colletotrichum dracaenophilum on Dracaena sanderiana in Bulgaria
Authors: Bobev S. G. , Castlebury L. A. , Rossman A. Y. 
Published: December 2007

In the winter of 2007, severe damage was observed on numerous indoor potted plants of Dracaena sanderiana hort. Sander ex Mast. (“lucky bamboo”) in Plovdiv, Bulgaria, which were imported from a country of unknown origin. These plants were already in the retail distribution stream. Initially, the internodes of infected stems appeared pale green with yellowish lesions. An upward spreading necrosis led to a weakness of the stems with wilt and death of the plants occurring within 2 weeks. Eventually, entire stems were covered with numerous, black, globose-to-ellipsoid acervuli with sparse, black setae. The fungus was aseptically isolated from stem lesions on potato dextrose agar (PDA) on which it produced fast-growing, pale pink colonies. On the plant and in culture, the conidia were hyaline, broadly clavate to cylindrical, occasionally slightly curved, and measured 20 to 34 × 6.7 to 10.0 μm (average 28 × 8.5 μm). On the basis of the symptoms on the plant and morphological, cultural, and molecular characteristics, the fungus was identified as Colletotrichum dracaenophilum D.F. Farr & M.E. Palm (1). Pathogenicity of the fungus was confirmed by artificial inoculation of healthy plants of D. sanderiana (three replicates). Stems were inoculated by inserting small mycelial plugs from 7-day-old PDA cultures into wounds that were subsequently covered with Parafilm strips. After 2 weeks, pale green lesions started developing on all inoculated plants and the fungus was successfully reisolated. No symptoms were found around the pure agar control wounds. The specimen from Bulgaria was deposited in the U.S. National Fungus Collections (BPI 877337) with the derived culture deposited as CBS 121453. In addition, the internal transcribed spacer region of the nrDNA of this isolate was sequenced and deposited as GenBank Accession No. EU003533. To our knowledge, this is the first report of C. dracaenophilum on potted plants outside of China and is the first report of this species in Bulgaria. Reference: (1) D. F. Farr et al. Mycol.

First Report of Powdery Mildew Caused by Podosphaera xanthii on Calendula officinalis in Italy
Authors: Garibaldi A. , Gilardi G. , Gullino M. L. 
Published: December 2007

Calendula officinalis L. (Asteraceae) (pot marigold or English marigold) is an ornamental species grown in gardens and as potted plants for the production of cut flower. It was also used in ancient Greek, Roman, Arabic, and Indian cultures as a medicinal herb as well as a dye for fabrics, foods, and cosmetics. During the summer of 2007, severe outbreaks of a previously unknown powdery mildew were observed on plants in several gardens near Biella (northern Italy). Both surfaces of leaves of infected plants were covered with dense, white mycelia and conidia. As the disease progressed, infected leaves turned yellow and died. Mycelia and conidia also were observed on stems and flower calyxes. Conidia were hyaline, ellipsoid, born in short chains (four to six conidia per chain), and measured 27.0 to 32.1 (31.4) × 12.9 to 18.4 (18.2) μm. Conidiophores measured 49 to 77.3 (67.2) × 8 to 13.3 (10.8) μm and showed a foot cell measuring 44 to 59 (51.9) × 9.3 to 12.6 (11.3) μm followed by one shorter cell measuring 15.6 to 18.9 (17.6) × 10.4 to 13.6 (12.2) μm. Fibrosin bodies were present. Chasmothecia were spherical, amber colored, with a diameter of 89 to 100 (94.5) μm. Each chasmothecium contained one ascus with eight ascospores. On the basis of its morphology, the causal agent was determined to be a Podosphaera sp. (2). The internal transcribed spacer (ITS) region of rDNA was amplified using the primers ITS4/ITS6 and sequenced. BLASTn analysis (1) of the 588 bp showed a 100% homology with the sequence of Podosphaera xanthii (2). The nucleotide sequence has been assigned GenBank Accession No. EU100973. Pathogenicity was confirmed through inoculations by gently pressing diseased leaves onto leaves of healthy C. officinalis plants. Five plants were inoculated. Five noninoculated plants served as control. Plants were maintained in a greenhouse at temperatures ranging from 20 to 26°C. Eleven days after inoculation, typical symptoms of powdery mildew developed on inoculated plants. Noninoculated plants did not show symptoms. The pathogenicity test was carried out twice. To our knowledge, this is the first report of powdery mildew on C. officinalis in Italy. C. officinalis was previously described as a host to Sphaerotheca fuliginea (synonym S. fusca) in Great Britain (4) as well as in Romania (3).

First Report of Puccinia kuehnii, Causal Agent of Orange Rust of Sugarcane, in the United States and Western Hemisphere
Authors: Comstock J. C. , Sood S. G. , Glynn N. C. , Shine J. M. , McKemy J. M. , Castlebury L. A. 
Published: December 2007

In June 2007, approximately 8 km east of Belle Glade, FL, a rust disease was observed on a sugarcane (a complex hybrid of Saccharum L. species) cultivar (CP 80-1743) considered resistant to brown rust caused by Puccinia melanocephala Syd. & P. Syd. Approximately 10 km south of Canal Point, FL, another cultivar (CP 72-2086), also considered resistant to P. melanocephala, was found to be infected with a rust. Samples were sent to the USDA-APHIS National Mycologist and the USDA-ARS Systematic Mycology and Microbiology Laboratory in Beltsville, MD for identification. Observed morphological features were consistent with P. kuehnii E.J. Butler. Uredinial lesions were orange and variable in size, measuring 650 to 850 × 26 to 32 μm, hypophyllous, ellipsoidal to fusiform in shape, and distinctly lighter than pustules of P. melanocephala that were present in the area along with P. kuehnii. Urediniospores were mostly obovoid to pyriform or broadly ellipsoidal, variable in size, 32 to 45 × 25 to 30 μm, and moderately echinulate with mostly evenly distributed spines 2 to 4.5 μm apart. Walls were orange-to-light cinnamon brown, 1 to 2.5 μm thick with a pronounced apical wall thickening as much as 7 μm, and 4 to 5 equatorial pores. Similar orange uredinial lesions were subsequently observed on the same two cultivars and several other cultivars, including CPCL99-1777 and CPCL01-1055, at different locations in South Florida. Telia and teliospores were not observed. The nuclear large subunit rDNA region of the rust infecting cv. CP 80-1743 (BPI 878243, GenBank Accession No. EU164549) and the ITS1, 5.8S, and ITS2 rDNA regions of the rust infecting CP 80-1743 (GenBank Accession No. EU176009) and CP 72-2086 (GenBank Accession No. EU176008) were sequenced (1,4). All sequences were identical to sequences of P. kuehnii and distinct from known sequences of P. melanocephala (4). To our knowledge, this is the first confirmed record of P. kuehnii infecting sugarcane in the Western Hemisphere, and the disease appears to be distributed widely in the South Florida sugarcane-growing area. Although listed by P. Holliday (3) as occurring in Cuba, the Dominican Republic, and Mexico, CMI map no. 215 ed. 4 (2) does not include these three countries in the known distribution of P. kuehnii. P. kuehnii has also been reported in the literature as present in Hawaii (4). However, examination of the specimen label found that the specimen cited in those papers (BPI 079624) was actually collected in Tahiti. Therefore, the report from Hawaii is erroneous.
