Abstract In June, 2001 the CITY2000 Foundation donated 500,000 photographic negatives, over 500 audio-and videotapes, and office archives to the University of Illinois at Chicago. The collection represents an image time capsule of a major American city during the year of the millennium. Every class of individual, event of the year, and neighborhood was explored by 200 professional photographers and brought together in this unique archive. As part of its agreement in accepting the archive, the UIC Library committed to making the collection available at least until the year 3000. This paper discusses the steps UIC is taking to make this possible. 相似文献

ABSTRACTAiming at contributing to the preservation of black and white (B&W) film-based negatives held by Portuguese archives, four photographic collections from the first half of the twentieth century were selected for study. During the macro assessment of the collections the preservation condition and hues found in photographic negatives from the Elmano Cunha e Costa (ECC) were noticed, distinguishing this collection from the remaining ones. Additional attention was given considering that the ECC collection was formed in a colonial context in the 1930s, while the others were formed on the Portugal mainland. The ECC collection results from an ethnographic survey of Angolan tribes recorded with B&W film-based negatives. In this collection, sets of negatives with pink, lemon yellow, greenish, orange brownish, and red brownish hues were found. To identify the origin of such hues, the image layer was analysed by microscale energy-dispersive X-ray fluorescence (μ EDXRF) and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX). Additionally, to assess the base decay and its effect on the formation of hues, the plastic supports were characterized by Fourier transform infrared microscopy (μ FTIR). To complement the assessment of the film-base decay, pH was measured by using combined microelectrodes. The identification of mercury, iodine, chromium, and iron by μ EDXRF allowed correlation of the hues found in the negatives with chemical corrective treatments performed to improve the image quality. SEM-EDX confirmed those results and proved that the elements found were in the photographic emulsion layer. The results obtained are relevant since the hues identified may now be used as markers to indicate the technical work performed on colonial photography. Additionally, the visual and molecular assessment of the negatives’ supports (good to fair condition) allow proposing that the original storage conditions may have had a beneficial contribution to their present condition. 相似文献

ABSTRACTThis experimental program, implemented by the Managing Collection Environment Initiative at the Getty Conservation Institute, has provided data about the response of historic objects to changes in relative humidity (RH). Alongside other less sensitive documentation techniques (visual observation, physical measurements, photography, and 3D scanning), acoustic emission (AE) was monitored for six historic, museum-like wooden objects exposed to gradually increasing RH variations. Quantitative calibration of AE sensors and an anti-correlation measuring scheme to reduce environmental noise allowed the AE system to effectively trace micro-damage development caused by environmentally induced stress. Using an epidemiological approach, with respect to sample selection and experimental protocol, the obtained results can be used to explore the acceptable range of climate fluctuations for museum collections. The study’s well-controlled environmental protocol also allowed for the examination of the concept of ‘proofed fluctuation’ by the analysis of object response to reoccurring conditions. 相似文献

While scholars have reviewed characterizations of photographers in feature films, they have neglected the image of real-world photographers in the documentary genre. This study incorporates visual representation theory to engage with several of the ways in which documentary filmmakers use the visual aspects of motion pictures to glamorize the lives and careers of photographers. As witnessed in four case study films, the analysis of this research highlights film's ability to generate representative character types. Specific aesthetic conventions of filmmaking are found to affect the on-screen projections of the photographer-subjects. The mostly positive depictions of “celebrity” or noteworthy real-world photographers also suggest that the documentaries under study primarily exist as marketing or publicity materials for the professional and his or her body of work. 相似文献

AbstractThere is a missing link in the strategic introduction of new materials in conservation, which lies between the identification of new processes/materials and their widespread use in conservation treatments. Clinical trials to monitor the results of treatment success provide an effective procedure to evaluate the conservation process. This is now possible due to the increasing power and widespread use in conservation laboratories of computers, which provide an analytical tool for evaluating and examining treatments and procedures. Information, such as object condition, is routinely generated during the conservation of objects. To use this information statistically, it has to be structured to answer specific questions. Medical professionals have already established epidemiological techniques as a means of evaluating patient health and treatment performance. These techniques can be applied to conservation questions to provide statistically valid answers. This is an important tool with which to judge and prioritize strategies in the conservation process. 相似文献

ABSTRACTEnglish medieval cathedrals are a group of buildings of exceptional significance and they contain collections of equal importance. Both the historic building fabric and the artefacts are vulnerable to environmental deterioration. However, unlike buildings owned by heritage organisations, the primary purpose of cathedrals is to further the Christian mission, and the conservation of the building and collections is required to be conducted within these constraints. Increasing visitor numbers and the installation of sophisticated exhibitions makes the task of conservation all the more demanding. Next to mechanical damage, environmental factors are the greatest source of deterioration to sensitive fabric and collections. However, until recently, there has been little systematic study of English cathedral environments and the effects of different uses and control measures. Detailed studies undertaken on 20 cathedrals in the past two decades have provided an insight into their environmental performance and how they differ as a group from many other historic buildings, as well as the passive conservation measures that can be implemented within their primary function. 相似文献

In recent years there has been an explosion of citizen-produced content appearing in mainstream media outlets. Terms such as convergent journalism, citizen journalism and user-generated journalism are all widely used in an attempt to define this growing phenomenon. This paper explores the specific genre of citizen photojournalism (CPJ). It is argued this is a definitive genre of its own and has important implications for audience perceptions due to the narrative or “storytelling” role of the visual mage. An “action genre” approach is used to examine how this new photographic genre has been enabled within current technological, cultural, political and economic environments That is to say, that photographic production processes, undertaken by amateur photographers are examined to identify patterns of activity that comprise the genre of CPJ. Through a review of existing literature on how citizens work in the field, and the way the resulting photographs are used in mainstream media, I offer a conceptual structure to delineate recognisable patterns of activity that comprise the genre of CPJ. The strength of this approach is that it allows me to describe CPJ in a way that reveals how external factors and the practice of citizens taking photojournalistic images impact upon the final product published in influential publications including popular press, books, magazines and internet publications. 相似文献

ABSTRACTLibrarians are increasingly embracing project management to guide their work outside of routine library operations. Some humanities scholars, too, especially within the digital humanities community, are bringing project management techniques to bear on scholarly digital projects. We argue that librarians and their diverse collaborators can apply project management practices to a broad range of research, teaching, and learning projects with collaborators beyond the library. Two case studies illustrate this argument, one from each author's experience: creating a community biodiversity wiki for West-Central Florida and redesigning an interdisciplinary first-year seminar around creating 3-D models of historic Venetian buildings. 相似文献

ABSTRACTThe impact of solvent vapour from two solvents, acetone and industrial denatured alcohol (IDA), commonly used in adhesive reactivation in textile conservation, when applied to artificially soiled silk fabric through either Gore-Tex® or Reemay® membranes for exposure times of either 1 or 3 min, was measured using microscopy and ImageJ to monitor the movement of the solid particulates of the soiling, and Fourier transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR) to monitor the movement of the oily components. Analysis using these techniques successfully showed the movement of large particulates through the textile and a decrease in the presence of oil. Analysis with FTIR-ATR showed that the application of solvent vapour by a poultice method produces more than just a surface change and the vapour can penetrate far enough into the fibres to cause a change in the level of oil through the entire textile. The results showed that the solvents and barrier membranes have characteristic differences which impact on the changes on the soiling. The application of acetone produced a greater change in the movement of oil on the front and back of the samples than the application of IDA, while a comparison between the barrier membranes showed a greater change occurring in the level of oil with the use of Gore-Tex® rather than Reemay®. The time of exposure to solvent vapour made little difference to the changes to the textile soiling. Quantitatively significant results were gathered from analysis of the changes in the oil measured with FTIR-ATR, and qualitative changes in the large particulate soiling, demonstrating the potential usefulness of ImageJ open access software in future historic textile soiling monitoring studies. 相似文献

Summary The Internet opens a wide range of possibilities for accessing materials from both traditional sources and more volatile areas-personal homepages, e-mail and discussion groups archives. Though the role of reference librarians to find the most relevant information for our users seems monumental in this medium, it is an area that needs the objective, ethical expertise of the librarian and archivist. In this 50th year of remembrance of the Holocaust, the Internet is especially active with information on that historic tragedy. Excerpts from accounts by one Hungarian and one Norwegian political prisoner interned in the camps are included as illustrations of material which may not have been found using more traditional research tools. 相似文献

AbstractNaturally occurring pigments used by Aborigines in rock paintings have been collected in Western Australia. They area red pigment (mainly hematite, Fe2O3)(from a red ochre mine worked until historic times by Aborigines, and a white pigment (huntite, Mg3Ca(CO3)4) which is still collected and used by Aborigines. Samples were also taken from rock paintings in which these pigments were used or were thought to have been used. The pigment samples were analysed to establish chemical, mineralogical, and physical properties. The paint samples were examined microscopically and with an electron probe to study their relationship with the rock surface and with other paint layers. The relationship between the pigments’ properties and their durability is discussed. 相似文献

PurposeThis paper aims to examine whether Altmetric data can be used as an indicator for identifying predatory journals.Design/methodology/approachThis is an applied study which uses citation and Altmetrics methods. The study selected 21 predatory journals from the Beall's list and Kscien's list, as well as 18 non-predatory open access journals from the DOAJ's list, in the field of Library and Information Science. The Altmetric score for articles published in these journals was obtained from the Altmetric Explorer, a service provided by Altmetric.com. Web of Science was used to search for citation data of articles published in these journals.FindingsThe predatory journals almost have no presence in social media, with poor Altmetric score. In contrast, non-predatory open access journals have a high presence rate and Altmetric score. There is a significant positive correlation between the number of articles cited and the number of articles having Altmetric score among non-predatory open-access journals, but not among predatory journals. Poor Altmetric score may be viewed as a potential characteristic of predatory journals, but other indicators would also need to be considered to determine whether a journal is predatory.Originality/valueDistinct from the traditional research methods, this study combined citation analysis and Altmetrics analysis. By comparing the characteristics of predatory journals and non-predatory open access journals, the findings contribute to the identification of predatory journals. 相似文献

AbstractInsect pests are an important source of concern in historic houses as the larval stages in particular can feed on a variety of important heritage materials, causing significant and sometimes irreparable damage to collections. Damage to wood and textiles is a special problem. The lifecycles of insects are sensitive to climate and require relatively warm conditions. There has been a significant increase in the presence of insect pests within historic houses in the early twenty-first century. The reasons may include: warmer winters, widespread use of natural fibres, less potent insecticides, and occupation of new niches indoors. The interior climate, especially increasing warmth, offers the potential for greater insect growth and survivability. Modelling changes in the temperature and humidity within the Cartoon Gallery at Knole, southern England, for the period 1770–2100 suggests a dramatic increase in favourable temperature conditions through the current century. 相似文献

ABSTRACTThis paper analyzes the process of crack saturation, which is fundamental to understanding why panel paintings have survived remarkably well in the uncontrolled environments of historic houses or places of worship for several centuries. The process of crack saturation was analyzed using finite element modeling. A double layer elastic model with fractured overlying paint layer was subjected to uniaxial tension. The critical separation between cracks was determined and compared with patterns observed in real paintings. In addition, the generation and propagation of delamination were studied to elucidate the effect of their propagation on the saturation distance of cracks, as well as the load carrying ability of the paint layer. Contributing modes of crack propagation and their significance are also discussed. The results demonstrate that shearing fracture mode dominates the process of delamination. The impact of crack saturation on the degree of relative humidity variation that is allowable is also discussed. 相似文献

AbstractA very moderate, non-destructive radioactivation of oil paintings, induced by thermal neutron bombardment, such that approximately only one in 1012 of the atoms comprising any painting is transformed into a radioactive species, has been found to produce temporary radioactivity sufficient to expose photographic film placed in direct contact with the paintings.The resulting autoradiographs resemble conventional X-radiographs in that they reveal structural details in depth of both the painting and its support. Since the radioactivities arising from the different elements within a painting decay in different manners and at different rates, a series of significantly distinct auto radiographs can be obtained of any painting by making exposures through appropriate filters and at varying times following the original activation. Analysis of such a series of autoradiographs permits the identification of a number of the pigments used in a painting, together with information about the manner in which they were originally laid down by the artist and their distribution throughout the body of the painting.Preliminary investigations have shown that the stability of oil paintings is unaffected by the activation procedure. The inherently necessary radiation dose absorbed by a painting as a result of activation sufficient for autoradiography is of the order of 50 rads. Paintings subjected to absorbed doses one hundred times as great as the dose necessary for autoradiography exhibit no changes in color, hardness, flexibility and solubility three years after their original activation. 相似文献
