This study examined the occurrence of color in dissertations and theses produced at the Pennsylvania State University over a nine year period. Since the most common preservation method for dissertations and theses is monochromatic microfilming, traditional treatment may result in a loss of information encoded in color in these resources. Results indicate a significant increase in the use of color over the time period studied. Variations in the amount of color use by discipline were also observed. Implications related to monochromatic microfilming and recommendations for long term preservation are discussed. 相似文献

The need to provide bibliographic access to a collection of original medical illustrations led the Library of the University of California, San Francisco, to search for a bibliographic control system and, not finding a satisfactory one, to develop one of its own, Part 1 of the report details the planning for such a development, including the need for bibliographic control of illustrations, the goals of the proposed system, design decisions and changes required, the type of system chosen, special subjects indexing needs, the required output, and staffing and budgetary needs. 相似文献

Two squirrel monkeys searched for a reward buried in 1 of 144 holes that formed a 12×12 grid (48×50 cm). An array of vertical, colored landmarks was placed on the grid, and their locations on the grid were changed from trial to trial. During training trials, the mealworm reward was placed either in the center of a square array of landmarks (Experiments 1 and 3) or midway between two landmarks (Experiment 2). On nonrewarded test trials, the monkeys searched among landmarks placed in the same arrays as those used in training and among landmarks placed in an expanded array (Experiments 1 and 2) or in an array intermediate between the two arrays used in training (Experiment 3). Distributions of searches on test trials indicated that the monkeys searched mostly within the configuration of the landmarks but that they had not coded the location of the reward as being either in the middle of the landmarks or at a fixed distance and direction from an individual landmark. 相似文献

This exploration of the role of information in helping people to develop and sustain feelings of belonging, or a sense of place, is based on a study that investigated the reasons for the high population turnover in the Northern Territory of Australia. The Northern Territory along with Darwin, its capital, has a number of unusual characteristics including geographical isolation. A key component of the theoretical framework for the research focuses on social information, which has similarities to the more commonly termed everyday life information. The specific concern is with the kind of information that helps people connect to a community and is clearly linked with social networking. The sample for the major empirical component for the article was recruited at Darwin's Mindil Beach Market. In telephone phone interviews with those who had agreed to participate, participants discussed how they learned about Darwin and the Northern Territory, and their views of Darwin as a place to live. Interpersonal contacts, including at the Market and at special events, were most often mentioned in relation to information, confirming literature findings on the importance of family and friends as an information source. Other sources were newspapers and physical markers around the City of Darwin. The conclusion is that the processes of social networking, which work well for some residents, could be enhanced through the use of information grounds, a concept widely discussed in the library and information science literature. Obvious information grounds in Darwin, where the usual processes could be enhanced by the distribution of information by formal information providers, include Mindil Beach Market and the special events for which Darwin is renowned. 相似文献

Both macroappraisal and the Australian records continuum-based DIRKS methodology have been influential in the New Zealand
debate on appraisal in recent years. The primary influence of macroappraisal has been in the area of prioritisation of appraisal
work. This paper considers New Zealand thinking on prioritisation, and the influences of risk management and functional analysis
on this issue. A lack of agreement on the purpose of appraisal in the professional literature is noted, and some personal
suggestions are offered on a model taking elements from macroappraisal and other methodologies. 相似文献
