The Centre of Memories: work in progress. Case of the Michel Giacometti Labour Museum, Setúbal, Portugal

The work on Social Memory, focused on the biographic method and the paths of immaterial Heritage, are the fabric that we have chosen to substantiate the idea of museum. The social dimensions of memory, its construction and representation, are the thickness of the exhibition fabric. The specificity of museological work in contemporary times resembles a fine lace, a meticulous weaving of threads that flow from time, admirable lace, painstaking and complex, created with many needles, made up of hollow spots and stitches (of memories and things forgotten). Repetitions and symmetries are the pace that perpetuates it, the rhythmic grammar that gives it body. A fluid body, a single piece, circumstantial. It is always possible to create new patterns, new compositions, with the same threads. Accurately made, properly made, this lace of memories and things forgotten is always an extraordinary creation, a web of wonder that expands fantasy, generates value and feeds the endless reserve of the community’s knowledge, values and beliefs.

Alfredo Pareja: ensayista y crítico (Del Historiador y el Ensayista)

La autora revisa la ensayística de Alfredo Pareja sobre temas de arte colonial, cultura y literatura. Da cuenta de la evolución de su noción de lo artístico desde 1933, cuando Pareja marca distancia con la generación anterior y con el arielismo vigente, al hacer suya la defensa del realismo social, más adelante, sin embargo, matizaría estos juicios en otros ensayos. Su postura crítica, en términos generales, no defiende la originalidad ni la forma del texto por sí mismas, sino el valor del contenido, el humanismo empieza a ser el hilo conductor de su narrativa e iluminador de su estética. Por otro lado, siente la necesidad de resignificar lo local en su contacto con lo universal, reconociendo el afán de contemporaneidad de su generación, su defensa de lo mestizo está presente en sus reflexiones sobre el barroquismo latinoamericano. Finalmente, resulta interesante que Pareja aproxime dos grandes momentos del arte ecuatoriano: la pintura y escultura colonial de la llamada escuela de Quito, y la propuesta estética de su generación.

A comparison of cross-hole electrical and seismic data in fractured rock

Cross-hole anisotropic electrical and seismic tomograms of fractured metamorphic rock have been obtained at a test site where extensive hydrological data were available. A strong correlation between electrical resistivity anisotropy and seismic compressional-wave velocity anisotropy has been observed. Analysis of core samples from the site reveal that the shale-rich rocks have fabric-related average velocity anisotropy of between 10% and 30%. The cross-hole seismic data are consistent with these values, indicating that observed anisotropy might be principally due to the inherent rock fabric rather than to the aligned sets of open fractures. One region with velocity anisotropy greater than 30% has been modelled as aligned open fractures within an anisotropic rock matrix and this model is consistent with available fracture density and hydraulic transmissivity data from the boreholes and the cross-hole resistivity tomography data. However, in general the study highlights the uncertainties that can arise, due to the relative influence of rock fabric and fluid-filled fractures, when using geophysical techniques for hydrological investigations.

Earthworms produce granules of intricately zoned calcite

Earthworms of the family Lumbricidae, which includes many common species, produce and secrete up to millimeter-sized calcite granules, and the intricate fine-scale zoning of their constituent crystals is unique for a biomineral. Granule calcite is produced by crystallization of amorphous calcium carbonate (ACC) that initially precipitates within the earthworm calciferous glands, then forms protogranules by accretion on quartz grain cores. Crystallization of ACC is mediated by migrating fluid films and is largely complete within 24 11 of ACC production and before granules leave the earthworm. Variations in the density of defects formed as a byproduct of trace element incorporation during calcite crystall growth have generated zoning that can be resolved by cathodoluminescence imaging at ultraviolet to blue wavelengths and using the novel technique of scanning electron microscope charge contrast imaging. Mapping of calcite crystal orientations by electron backscatter diffraction reveals an approximate radial fabric to the granules that reflects crystal growth from internal nucleation sites toward their margins. The survival within granules of ACC inclusions for months after they enter soils indicates that they crystallize only within the earthworm and in the presence of fluids containing biochemical catalysts. The earthworm probably promotes crystallization of ACC in order to prevent remobilization of the calcium carbonate by dissolution. Calcite granules vividly illustrate the role of transient precursors in biomineralization, but the underlying question of why earth-worms produce granules in volumes sufficient to have a measurable impact on soil carbon cycling remains to be answered.

Analysis and application of ichnofabrics

Bioturbation at all scales, which tends to replace the primary fabric of a sediment by the ichnofabric (the overall fabric of a sediment that has been bioturbated), is now recognised as playing a major role in facies interpretation. The manner in which the substrate may be colonized, and the physical, chemical and ecological controls (grainsize, sedimentation rate, oxygenation, nutrition, salinity, ethology, community structure and succession), together with the several ways in which the substrate is tiered by bioturbators, are the factors and processes that determine the nature of the ichnofabric. Eleven main styles of substrate tiering are described, ranging from single, pioneer colonization to complex tiering under equilibria, their modification under environmental deterioration and amelioration, and diagenetic enhancement or obscuration. Ichnofabrics may be assessed by four attributes: primary sedimentary factors, Bioturbation Index (BI), burrow size and frequency, and ichnological diversity. Construction of tier and ichnofabric constituent diagrams aid visualization and comparison. The breaks or changes in colonization and style of tiering at key stratal surfaces accentuate the surfaces, and many reflect a major environmental shift of the trace-forming biota. due to change in hydrodynamic regime (leading to non-deposition and/or erosion and/or lithification), change in salinity regime, or subaerial exposure. The succession of gradational or abrupt changes in ichnofabric through genetically related successions, together with changes in colonization and tiering across event beds, may also be interpreted in terms of changes in environmental parameters. It is not the ichnotaxa per se that are important in discriminating between ichnofabrics, but rather the environmental conditions that determine the overall style of colonization. Fabrics composed of different ichnotaxa (and different taphonomies) but similar tier structure and ichnoguild may form in similar environments of different age or different latitude. Appreciation of colonization and tiering styles places ancient ichnofabrics on a sound processrelated basis for environmental interpretation. (C) 2002 Elsevier Science B.V. All rights reserved.

Confronting social defence mechanisms: avoiding disorganization during crises

Crises cause social disturbances within their host organisation and the patterns of interpersonal ties that emerge are an important determinant of crisis management efficiency. In this article, social network analysis is used within a construction project context, to demonstrate that efficient crisis management depends upon the design and maintenance of an appropriate social fabric. However, crises have defence mechanisms that make management difficult by inducing forces that encourage people to pursue inappropriate social ties. Purposeful social intervention is therefore an essential part of the crisis management process to confront and avoid disorganisation.

Interdependency and care over the lifecourse

Interdependency and Care over the Lifecourse draws upon theories of time and space to consider how informal care is woven into the fabric of everyday lives and is shaped by social and economic inequalities and opportunities. The book comprises three parts. The first explores contrasting social and economic contexts of informal care in different parts of the world. The second looks at different themes and dynamics of caring, using fictional vignettes of illness and health, child care, elderly care and communities of care. The book examines the significance to practices of care throughout the lifecourse of: understandings and expectations of care emotional exchanges involved in care memories and anticipations of giving and receiving care the social nature of the spaces and places in which care is carried out the practical time-space scheduling necessary to caring activities. Finally the authors critically examine how the frameworks of caringscapes and carescapes might be used in research, policy and practice. A working example is provided. This book will be of interest to students and researchers of care work, health and social care, geography, sociology of the family and social policy as well as those in business and policy communities trying to gain an understanding of how work and informal care interweave

Taxonomical musings

In the ‘Object as Subject’ exhibition held at the Stephen Lawrence Gallery, Greenwich University, myself and two other artists showed work which explores the use of the ‘found object’ in their respective practices. My work was selected by the gallery curator David Waterworth. The work exhibited by me, two multi-media pieces and two films, continues my (practice as research) investigation into using everyday objects as starting points for creating work in a variety of mediums including: sculpture, films, installations and multiples. In this work I address a range of subject matters – philosophical, social and cultural. The history of the use of found object in art began in early 20th century European art when Marcel Duchamp and Pablo Picasso independently introduced everyday objects into their practice. My work continues this research.
