Included in the Gallery for a Collector was Hamilton's 1957 painting Hommage à Chrysler Corp. The essay treats both the gallery and the painting as ,meta-aesthetic' practices that register something of the aesthetic historicity of their social and cultural moment. To demonstrate how the work relates to the historicity of perception (sensorial, social and political perception) and to the material culture of the time, the essay sets out a number of possible contexts for attending to the painting and the Ideal Home installation. [source] Raycasting of Light Field Galleries from Volumetric DataCOMPUTER GRAPHICS FORUM, Issue 3 2008C. Rezk-Salama Abstract The paper describes a technique to generate high-quality light field representations from volumetric data. We show how light field galleries can be created to give unexperienced audiences access to interactive high-quality volume renditions. The proposed light field representation is lightweight with respect to storage and bandwidth capacity and is thus ideal as exchange format for visualization results, especially for web galleries. The approach expands an existing sphere-hemisphere parameterization for the light field with per-pixel depth. High-quality paraboloid maps from volumetric data are generated using GPU-based ray-casting or slicing approaches. Different layers, such as isosurfaces, but not restricted to, can be generated independently and composited in real time. This allows the user to interactively explore the model and to change visibility parameters at run-time.

The new gallery cost over £100,000 and took ten years to complete, during which time Duveen worked hard to impose his vision of a new gallery , a vision often at odds with that of the Museum establishment, and one that generated controversy, including the unauthorized cleaning of the marbles.

[source] The Animated Muse: An Interpretive Program for Creative ViewingCURATOR THE MUSEUM JOURNAL, Issue 3 2005Austin Clarkson ABSTRACT Explore a Painting in Depth, an experiment presented in the Canadian Collection of the Art Gallery of Ontario, consisted of a booth that offered seating for two visitors and, opposite them, The Beaver Dam, a 1919 landscape painting by the Canadian artist J. E. H. MacDonald. In a 12-minute audio-guided Exercise for Exploring, visitors were invited to engage in a creative process with the imagery of the painting. This paper sketches how the experiment evolved, presents the background of the Exercise for Exploring, and surveys the effects of the exhibit on a wide range of visitors. The question is raised: How can facilitating visitors' creative responses to artworks be part of the museum's educational mandate and its arsenal of interpretive resources? More broadly: Do strategies that foster and privilege visitor creativity, as well as honor the creativity of artists, affect the accessibility and relevance of the museum for the general public?

It was led by artist Laurie Long with teachers and pupils from Pooles Park primary school in Islington, an inner city borough in North London. Based on the production of a postcard featuring an image of personal significance, the children were involved in exploring and constructing their own and others' identities whilst developing their technology skills in creative ways. The project raises interesting questions about the applicability of contemporary art practices to the primary classroom. The research is based on participant observation and includes the voices of the artist and teachers involved. [source] Gallery of the Future: New Directions in Arts EducationINTERNATIONAL JOURNAL OF ART & DESIGN EDUCATION, Issue 1 2000Ken Baynes The arts at the end of the 20th Century are dynamic: they are playing an increasingly important role in the life of individuals and the structuring of society. But they are also changing dramatically. It is my argument that arts education will need to change practice to match. The aim here is to discuss some of the key changes and values that will require a response from schools. Where do we look for evidence of these changes? Can we say what they are? I believe that we can. There are specific themes or directions now current in the arts which are likely to continue into the future. In the main they stem from the dynamism created by the interaction between art, technology and social change.

Work is primarily initiated by a senior undergraduate option studio offered in the Spring then augmented by a construction techniques elective open to both graduate and undergraduate students. Small Built Works has completed twenty-seven streetscape projects in Buffalo's urban core since 2001 under the management construct of six conceptual projects that have generated four approved building permits. These six projects are the Community Transformation Project (2001,2004), the Bus Shelter Project (2002,2005), the Gateway Project (Kiosk and Planter 2003,2005), the Totem Project (Mardi Gras float and the Connecticut Street Sculpture Park 2004,2006), the El Museo Gallery (2005,2006), and the Greening Collaborative Project (2006). In 2005, the Small Built Works Project won the National Council of Architecture Registration Boards Grand Prize for the creative integration of education and practice. This presentation is broken down into three aspects of the concept of 1:1 inherent in the work. [source] Nursing Education at an Art GalleryJOURNAL OF NURSING SCHOLARSHIP, Issue 2 2000Britt-Maj Wikström Purpose: To introduce an experiential teaching-learning method in nursing education based on art gallery visits. Works of art communicate a broad spectrum of human experiences and thoughts, and can be useful when studying interpersonal relations. Design: Theoretical framework on experiential learning was based on writings of Dewey and Burnard. Data were collected from nursing students (N = 206) at a university college of health sciences in Sweden during a 3-year period, 1995,1998. Method: The pedagogical approach was experiential and based on three phases: observation, conceptualisation, and reflection. When students visited the art gallery, they were encouraged to look for metaphoric expressions of interpersonal relations. Students were asked to interpret the art, report findings to fellow-students, and evaluate the program. Findings: Studying works of art was a powerful teaching-learning method for understanding interpersonal relations. Students related interpretations of a work of art to interpersonal relations in nursing. Conclusions: Nursing students' observations and understanding of interpersonal relations were enhanced by the art gallery program.

In the last 20 years, the social role of photography has shifted: from origins in scopic regimes that racialized and dispossessed Aboriginal peoples to an era of contemporary reappropriation, recontextualizing colonial archives, and producing new Indigenous high art photography. Photographs are no longer stable, visible testimony of Indigenous peoples' presumed imminent decline or innate savagery but are, rather, colonial objectifications now available for resignification as evidence of kinship networks, land claims, and local knowledge systems. In July 2006, two exhibitions were spearheading these important transitions. "Colliding Worlds" opened at Melbourne Museum, and "Michael Riley: Sights Unseen" premiered at the National Gallery of Australia (NGA) in Canberra. Together, these exhibitions destabilize historical legacies of the visual in Australia's national imaginary, resignifying photography as a medium of new knowledge production, aesthetic expression, and social change. [source] Front and Back Covers, Volume 21, Number 5.ANTHROPOLOGY TODAY, Issue 5 2005October 200 Front and back cover caption, volume 21 issue 5 Front cover Children in the favela (squatter community) of 'Caxambu', in the northern zone of Rio de Janeiro, Brazil. Although favelas are often depicted as dangerous and as the housing option of last resort, they are also characterized by dense and multi-stranded social ties between residents, long histories of occupation and settlement, and multi-generational families. Caxambu (a pseudonym) was originally settled at the beginning of the 20th century, and residents often describe the neighbourhood as a 'big family'. As the photo makes clear, the alleys, street corners and other public spaces in the favela often serve as giant playgrounds for local children. Back cover THE HUMAN BODY The photo on the back cover shows one of the exhibits from Gunther von Hagens' anatomical exhibition Body Worlds, discussed by Uli Linke in this issue. The exhibits in this show are fashioned from human corpses. The male figure shown here, the body of a man holding and gazing at his own skin, attempts to convey something about the human skin. The anatomical museum markets corpses, artfully transformed to appeal to the viewer. Body Worlds has toured internationally, and attracted millions of visitors. Dead bodies are transformed into sensually appealing 'works of art', playing to fantasies of the alluring body common to the dream worlds promoted by multinational media and entertainment industries. In the exhibition anatomy and pedagogy, economy and medical science, pathology and human rights are closely intertwined. But where do the bodies come from? The corpses, contrary to the exhibitor's claims, are not supplied by German donors - they are procured from Eastern Europe, Russia, Kyrgyzstan and China, from places where human rights and bioethical standards are not enforced. Von Hagens insists that bodies displayed are from donors, and his exhibition website (www.bodyworlds.com) welcomes donations to its body donation programme. In his body factory in Dalian, China, thousands of corpses, including the remains of executed prisoners, are flayed and prepared for later use. This trade in bodies, a multi-million-dollar enterprise, is highly problematic. For the trumpeted 'art of anatomy', with its beautified corpses and eroticized installations, also has a violent dimension, with human victims whose bodies are bought and sold for profit. In November 2002, Gunther von Hagens risked prosecution by holding the first public dissection of a (donated) body in the UK since the 1830s, in London's Atlantis Gallery. The issues surrounding procurement, preparation, dissection and display of human remains are central to anthropology, and in this article Uli Linke discusses in particular the various ways in which this exhbition was interpreted in Germany.

[source] From the Gallery to the Parliament: Journalists in the House of Representatives and Senate, 1901,2007AUSTRALIAN JOURNAL OF POLITICS AND HISTORY, Issue 4 2009Wayne Errington In this article we examine the extent of career cross-over from journalism to politics in Australia using biographical data on the pre-parliamentary careers of federal politicians since 1901. We find that while journalists continue to be over-represented in Australia's national Parliament, there is evidence of a decline in the number making the career switch to politics. We argue that one explanation for this is the growing professionalisation of both vocations, and of journalism especially. Journalism education inculcates in graduates a strong sense of the media's Fourth Estate role, contributing to a professional identity that militates against taking up a political career. We also find that in recent decades, in spite of a small number of celebrated cases of journalists joining the ranks of the ALP, prior careers in journalism have been more prevalent among Coalition MPs. We argue that this reflects an ALP pre-selection system that has become less accommodating of all pre-parliamentary occupations other than trade union official and political staffer.

[source] Bacteria in oral secretions of an endophytic insect inhibit antagonistic fungiECOLOGICAL ENTOMOLOGY, Issue 6 2006YASMIN J. CARDOZA Abstract 1.,Colonisation of host trees by an endophytic herbivore, the spruce beetle, Dendroctonus rufipennis, is accompanied by invasion of its galleries by a number of fungal species. Four of these associated species were identified as Leptographium abietinum, Aspergillus fumigatus, Aspergillus nomius, and Trichoderma harzianum. 2.,Trichoderma and Aspergillus significantly reduced spruce beetle survival and reproduction in controlled assays. 3.,A previously undescribed behaviour was observed, in which spruce beetle adults exuded oral secretions, especially within fungus-pervaded galleries. 4.,These oral secretions inhibited the growth of fungi except A. nomius, and disrupted the morphology of the latter. Administration of these secretions indicated a dose-dependent inhibitory effect. 5.,Oral secretions cultured on microbiological media yielded substantial bacterial growth. 6.,Filter-sterilised secretions failed to inhibit fungal growth, evidence that the bacteria are responsible for the antifungal activity. 7.,Nine bacterial isolates belonging to the Actinobacteria, Firmicutes, Gammaproteobacteria, and Betaproteobacteria taxa were obtained from the secretions. 8.,Bacterial isolates showed species-specific inhibitory activity against the four fungi antagonistic to spruce beetle. The bacterium with the strongest fungal inhibition activity was the actinomycete Micrococcus luteus. 9.,The production of bark beetle secretions containing bacteria that inhibit fungal growth is a novel finding. This suggests an additional level of complexity to ecological associations among bark beetles, conifers, and microorganisms, and an important adaptation for colonising subcortical tissue. [source] Density-mediated responses of bark beetles to host allelochemicals: a link between individual behaviour and population dynamicsECOLOGICAL ENTOMOLOGY, Issue 4 2002Kimberly F. Wallin Abstract ,1. Bark beetles (Coleoptera: Scolytidae) accept or reject host conifers based partly on concentrations of phloem monoterpenes. They colonise trees in aggregations, in response to pheromones that attract flying beetles to trees undergoing colonisation. A series of entry and gallery construction assays was conducted to determine whether responses by individual beetles to monoterpenes are altered by pheromones and/or the presence of other beetles. 2. Entry into the amended media by Ips pini and the length of time until entry were not influenced by the presence of aggregation pheromones. 3. Entry into amended media was influenced by the presence of other beetles on the surface of, or constructing galleries in, the substrate. The effects of alpha-pinene and limonene on host entry behaviour were mediated by the density of beetles on the surface of the assay arena, and by the density of beetles constructing galleries within the medium. 4. The percentage of beetles entering medium amended with higher concentrations of monoterpenes increased with increased density of beetles on the surface of the assay arena, until a threshold density of three or four beetles per assay arena, after which entrance rate declined. 5. The presence of other beetles constructing galleries elicited more rapid entry by the test beetles. 6. Gallery lengths were generally higher in the presence of aggregation pheromones. 7. Gallery lengths increased with increased density of beetles within the assay arena. 8. These results suggest a link between the density of bark beetles and responses of individuals. This linkage may partially explain behavioural changes observed during population eruptions. [source] Effect of termites on clay minerals in tropical soils: fungus-growing termites as weathering agentsEUROPEAN JOURNAL OF SOIL SCIENCE, Issue 4 2002P. Jouquet Summary Termites of the subfamily Macrotermitinae play an important role in tropical ecosystems: they modify the soil's physical properties and thereby make food available for other organisms. Clay is important in the architecture of Macrotermitinae termite nests, and it has been postulated that termites could modify the mineralogical properties of some clays. We have tested this hypothesis of clay transformation by termites in the laboratory under controlled conditions, using Odontotermes nr. pauperans termite species, one of the main fungus-growing species at Lamto Research Station (Côte d'Ivoire). Soil handled by termites in nest building was saturated with SrCl2, glycol or KCl and afterwards heated at 250°C for X-ray diffraction analyses. Termite handling led to an increase in the expandable layers of the component clay minerals. Heating and saturation by potassium of modified clays did not close the newly formed expandable clay layers. However, differences occurred between parts of the constructions built by termites, and the clays can be ranked according to their degree of alteration in the following order: unhandled soils < galleries < chamber walls. Consequently, termites can be seen as weathering agents of clay minerals, as previously shown for micro-organisms and plants. [source] Selection on defensive traits in a sterile caste , caste evolution: a mechanism to overcome life-history trade-offs?EVOLUTION AND DEVELOPMENT, Issue 1 2009Estelle A. Roux SUMMARY During development and evolution individuals generally face a trade-off between the development of weapons and gonads. In termites, characterized by reproductive division of labor, a caste evolved,the soldiers,which is completely sterile and which might be released from developmental trade-offs between weapons and testes. These soldiers are exclusively dedicated to defense. First, we investigated whether defensive traits are under selection in sterile termite soldiers using allometric analyses. In soldiers of the genus Cryptotermes phragmotic traits such as a sculptured and foreshortened head evolve rapidly but were also lost twice. Second, we compared the scaling relationships of these weapons with those in solitary insects facing a trade-off between weapons and gonads. Defensive traits consistently had lower slopes than nondefensive traits which supports the existence of stabilizing selection on soldier phragmotic traits in order to plug galleries. Moreover, soldier head widths were colony specific and correlated with the minimum gallery diameter of a colony. This can proximately be explained by soldiers developing from different instars. The scaling relationships of these termite soldiers contrast strikingly with those of weapons of solitary insects, which are generally exaggerated (i.e., overscaling) male traits. These differences may provide important insights into trait evolution. Trade-offs constraining the development of individuals may have been uncoupled in termites by evolving different castes, each specialized for one function. When individuals in social insect are "released" from developmental constraints through the evolution of castes, this certainly contributed to the ecological and evolutionary success of social insects. [source] Botryozyma mucatilis sp. nov., an anamorphic ascomycetous yeast associated with nematodes in poplar slime fluxFEMS YEAST RESEARCH, Issue 8 2004Julia Kerrigan Abstract A new species of Botryozyma, Botryozyma mucatilis, was isolated from the surface of free-living nematodes, Panagrellus dubius, inhabiting slime flux from hybrid poplars, Populus deltoides×trichocarpa, in Oregon, USA. This species was discovered in relatively close proximity to the teleomorphic species Ascobotryozyma americana and Ascobotryozyma cognata, both collected from P. dubius nematodes inhabiting beetle galleries in Populus spp. and Populus and Salix spp., respectively. B. mucatilis is recognized as a distinct species based on molecular and morphological data. Sequence divergence in both the D1/D2 domain of the nuclear large-subunit rDNA and internal transcribed spacer region rDNA, low DNA reassociation values, notably different amplified fragment-length polymorphic fingerprints, and significantly longer cells all support the designation of a novel species. [source] Fungi isolated from Picea abies infested by the bark beetle Ips typographus in the Bia,owie,a forest in north-eastern PolandFOREST PATHOLOGY, Issue 2 2010T. Kirisits Summary The assemblage of fungi occurring in the sapwood of Norway spruce (Picea abies) and in bark beetle galleries following attack by the Eurasian spruce bark beetle Ips typographus was investigated in the Bia,owie,a forest in north-eastern Poland. Fungi were isolated from blue-stained sapwood of beetle-infested spruce trees in June 2002, and a few isolates were also obtained from ascospores and conidia taken from perithecia and asexual structures occurring in the gallery systems of the insects. The mycobiota of I. typographus in the Bia,owie,a forest was dominated by ophiostomatoid fungi, which were represented by seven species. Four species, including Ceratocystis polonica, Grosmannia penicillata, Ophiostoma ainoae and Ophiostoma bicolor were isolated at high frequencies, whereas three other taxa, Ceratocystiopsis minuta, Ceratocystiopsis alba and a Pesotum sp. were rare. The anamorphic fungus Graphium fimbriisporum and yeasts also occurred occasionally. In addition, the basidiomycete Gloeocystidium ipidophilum was relatively common. The pathogenic blue-stain fungus C. polonica was the dominant fungal associate of I. typographus in the Bia,owie,a forest, which is consistent with a previous study at this area in the 1930s. Ceratocystis polonica was the most frequently isolated species at the leading edge of fungal colonization in the sapwood and had on an average penetrated deeper into the wood than other fungal associates. This suggests that it acts as a primary invader into the sapwood after attack by I. typographus in the Bia,owie,a forest, followed by O. bicolor, O. ainoae, G. ipidophilum and G. penicillata. Thus far, the Bia,owie,a forest is one of the few areas in Europe, where C. polonica has been reported as a dominate fungal associate of I. typographus. [source] Associations between Pityogenes bidentatus and fungi in young managed Scots pine stands in PolandFOREST PATHOLOGY, Issue 3 2008R. Jankowiak Summary The association between Pityogenes bidentatus and fungi was studied in young, managed Pinus sylvestris stands in Poland. Fungi were isolated from emerged adults and their galleries collected from four populations. In total, 2089 fungal isolates including 42 species, were obtained. Penicillium sp. 1 and Geosmithia sp. 1 were the most commonly isolated fungi from beetles (49% and 41% of beetles respectively). Geosmithia sp. 1 species was the dominant species in P. bidentatus galleries with a frequency of occurrence of 57.9%. Hormonema dematioides was the second most abundant fungus in gallery systems (17.1% of wood samples). Two of the isolated Geosmithia species were previously undescribed. Pityogenes bidentatus also vectored three ophiostomatoid species: Ophiostoma minus, O. piceae and Graphium sp. ,W'. These species were occasionally isolated from beetles and their galleries, suggesting a non-specific relationship.

[source] TEM-fast small-loop soundings to map underground tunnels and galleries connecting the rock-hewn churches of Lalibela, EthiopiaGEOARCHAEOLOGY: AN INTERNATIONAL JOURNAL, Issue 5 2005Gaetano Ranieri As one of the first attempts to utilize the technique for intrasite archaeological prospection, a series of coincident square-loop TEM-fast geophysical surveys were carried out over the compounds of the largest of the rock-hewn churches of Lalibela,Bete Maryam and Bete Amannuel,in North Ethiopia. Archaeologists have long believed that the different churches within each group were connected by underground tunnels. The aim of this survey was to identify, delineate, and map these underground channels and galleries. A total of 33 sounding surveys were conducted, the majority of which used a 3-m-side square loop. The survey traverses explored around the sides of the churches where underground connections to the other churches are possible. The results of the surveys, which are presented in terms of resistivity and depth pseudosections, clearly depict the presence of anomalies that could be associated with cavities, whose orientation suggests the presence of connecting galleries between the different churches. Whether these cavities were actually connecting galleries with religious implications or designed to be used as drainage paths remains a subject requiring further study involving additional geophysical investigations and physical excavation. © 2005 Wiley Periodicals, Inc. [source] Moderate Bioclogging Leading to Preferential Flow Paths in BiobarriersGROUND WATER MONITORING & REMEDIATION, Issue 3 2006Katsutoshi Seki Permeable reactive barriers (PRBs) are an alternative technique for the biological in situ remediation of ground water contaminants. Nutrient supply via injection well galleries is supposed to support a high microbial activity in these barriers but can ultimately lead to changes in the hydraulic conductivity of the biobarrier due to the accumulation of biomass in the aquifer. This effect, called bioclogging, would limit the remediation efficiency of the biobarrier. To evaluate the effects bioclogging can have on the flow field of a PRB, flow cell experiments were carried out in the laboratory using glass beads as a porous medium. Two types of flow cells were used: a 20- × 1- × 1-cm cell simulating a single injection well in a one-dimensional flow field and a 20- × 10- × 1-cm cell simulating an injection well gallery in a two-dimensional flow field. A mineral medium was injected to promote microbial growth. Results of 9 d of continuous operation showed that conditions, which led to a moderate (50%) reduction of the hydraulic conductivity of the one-dimensional cell, led to a preferential flow pattern within the simulated barrier in the two-dimensional flow field (visualized by a tracer dye). The bioclogging leading to this preferential flow pattern did not change the hydraulic conductivity of the biobarrier as a whole but resulted in a reduced residence time of water within barrier. The biomass distribution measured after 9 d was consistent with the observed clogging effects showing step spatial gradients between clogged and unclogged regions.
