当孤独的人生之旅走过生命的正午,如火的太阳灸烤着青春的脊背,向前眺望,那梦幻的巅峰仍遥遥无期,空蒙的远方一片迷茫,严寒酷暑,年复一年,那追梦的脚步疲惫了,奔放的热血平静了。蓦然回首,人生的四十年过去了。岁月的沟回,年轮般刻上青春的额角,那飘飞的黑发,让片片初霜飞落鬓角。哦,是谁,站在四十岁的伤感之野,面对苍穹点燃一支心香,遥记那掀去的四十年。那是诗与梦,笑与泪的四十年。梦幻的花朵缤纷绽放,青春的脚步步步生莲。回忆的宫殿里,到处是红帆船,蓝仙子和芝麻开门。在尘世的众生中,青春的头颅高高昂起;在岁月的激流里,年轻的臂膀逆流而上。未来的君主,梦幻的帝王,以青春为骄傲,把明天当作希望。在那流光溢彩的年华里,是谁,忘了把心中回荡的旋律谱成美丽的青春之歌,是谁啊,站在红烟绿雾的岁月河畔,却没有留下一幅人生的画图。回首青春,渺如蔚蓝的天空,美丽,而一无所有。岁月,象蛀虫一样噬咬着人的奋斗意志,泯灭着理想的火焰,偶然一天,当你走进从未去过的医院,竟一住就是四十天。你才知道,生命是如此脆弱。当你在牌桌上耗费一个又一个通宵而不能罢时,你才知道,生命的惰性是如此深重。当青云直上的童年好友面对你急切的请求冷冷一笑,你才知道,什么是世态炎凉。青春的明天就是这些吗?怎能料到,爱情的挫折,疾病的纠缠,生活的变故,人世的暗箭,更有生命的惰性和生活的负担。这一切,如一把把锋利的刀刃,削去青春 相似文献

Planning a conference at the best of times is intense. Add in a lingering pandemic and the first attempt at a hybrid conference then planning a conference can become extremely stressful. Selecting sessions for a conference can fall under the responsibilities of librarians contributing to the profession and completing service requirements. This paper maps the research, creation, and implementation of a rubric to guide the evaluation of session proposals for a technical services library conference and the creation of a webpage to inform those thinking of submitting a proposal. The deliverables were a page added to the organization website and a rubric. 相似文献

How are libraries used as meeting places, and by whom? Through survey data, six categories of places are identified: the library as a “square,” as a place for meeting diverse people, as a public sphere, as a place for joint activities with friends and colleagues, as a metameeting place, and as a place for virtual meetings. Representative samples of the population in three townships in Oslo, each with a markedly different demographic profile, are surveyed. Multivariate regression analyses are performed to analyze why some people use the library for a range of meetings and others do not, as well as to examine variations in the use of the library for different kinds of meetings. Public libraries are shown to be used for a variety of meetings. Community involvement is more important than township and demographic variables in explaining variations in use of the library as a meeting place. Correlations between low income and low education and high use of the library as a meeting place were found, indicating that the library as a meeting place plays a substantial role in equalizing the possibilities of being an active citizen across social and economic differences. The study contributes to understanding the role of the public library in a multicultural context. The public library as a unique and complex meeting place has important implications for future librarianship. 相似文献

Measuring Search Engine Quality 总被引：12，自引：3，他引：9
The effectiveness of twenty public search engines is evaluated using TREC-inspired methods and a set of 54 queries taken from real Web search logs. The World Wide Web is taken as the test collection and a combination of crawler and text retrieval system is evaluated. The engines are compared on a range of measures derivable from binary relevance judgments of the first seven live results returned. Statistical testing reveals a significant difference between engines and high intercorrelations between measures. Surprisingly, given the dynamic nature of the Web and the time elapsed, there is also a high correlation between results of this study and a previous study by Gordon and Pathak. For nearly all engines, there is a gradual decline in precision at increasing cutoff after some initial fluctuation. Performance of the engines as a group is found to be inferior to the group of participants in the TREC-8 Large Web task, although the best engines approach the median of those systems. Shortcomings of current Web search evaluation methodology are identified and recommendations are made for future improvements. In particular, the present study and its predecessors deal with queries which are assumed to derive from a need to find a selection of documents relevant to a topic. By contrast, real Web search reflects a range of other information need types which require different judging and different measures. 相似文献

Mass representations of the sublime use apostrophe as a mode of address that normalizes a moment of expected failure of discourse. Regardless of whether a viewer experiences “sublimity,” mass representations of what is supposedly beyond discourse embody the expected limits of communication, aestheticizing conditions of impossibility for discourse, and thereby constituting a space wherein the humanist subject may become a recognizable self in a public sense. Constituting a relationship between the spectator as human and the sublime objects as greater than human, a mass reproduced sublime thus helps establish discursive spaces of humanism. Although the aesthetics of the sublime can be exceptionally varied, the essay applies these ideas to popular Ansel Adams photographs, which illustrate the problems of attempting to represent the unrepresentable and the invocation of a particular kind of subjectivity as a commonplace. 相似文献

The unprecedented growth in U.S.-China film coproductions and Chinese companies’ high-profile investment in Hollywood studios and U.S. cinemas signal a shift in global power relationships and a reshaping of the global media structure. Combining textual and document analysis with interviews of policy makers and film professionals in China and Hollywood, this article explores the implications of U.S.-China coproduction for global communication. The article proposes three ways of understanding coproductions: as a market-driven and profit-seeking partnership, as a policy and power negotiation, and as a brave experimental adventure. This article contends that the current state of U.S.-China coproduction manifests the contradiction between desire and reality. Although coproductions have the potential to create a space for a new global culture, to develop innovative communication models, and to achieve a China-U.S. consensus, the fulfillment of these potentials will require a steadfast effort and the commitment of more than one generation of filmmakers from both China and the U.S.A. Nevertheless, a global culture and a reshaping of the global media structure are in the making. 相似文献

This phenomenological study examines the unique perceptions of immigrant women concerning the public library as a meeting place, a support to integration into American culture, and a provider of programs for acquisition of the English language. The library offers a place for observing the culture of the new country from a distance to active participation; it is an arena for comfort and consolation in a difficult life situation as well as an arena for activity and participation. It provides support in developing friendships, acclimating to a new culture, learning a new language, and providing avenues to employment. Three mothers, who fulfilled the criteria for the study, were selected from an initial focus group. Women from Kurdistan, Mexico, and Indonesia were interviewed individually to gain an understanding on the issues brought forth in the focus group. They participated in interviews over the course of 6 months. These programs became a fortuitous blending of an established community with a group of families looking for a support community in a new country. This study has implications for institutions serving immigrants as they look to find a community of support, to learn English, and to acclimate to American culture as they create a comfortable identity that blends their home country with the new country. 相似文献

Since 1962 the members of the loosely organized Detroit Medical Library Group have carried on a slow but steady self-examination program. They found a need to increase resources and developed a periodical exchange, then a need to identify these resources and did so by means of a serials list. More recently, a similar program for texts and monograph resources was begun. Data, more particularly that of the interlibrary loan process, is being gathered to show the flow within the area and the flow from outside to further identify the existing resources. They have made contact with the administrators of the biomedical institutions and gained their backing (a) to further study the makeup of the community and (b) to formulate an administrative structure through which these institutions can act. These activities are evidence of the beginning of a strong medical library network for the Metropolitan Detroit Area. 相似文献

A highly parallel single-chip image signal processor architecture has been derived by analysis of image processing algorithms. Available levels of parallelism and their associated demands on data access, control and complexity of operations were taken into account. The RISC-architecture, called “HiPAR-DSP”, consists of a control unit, 16 parallel ASIMD-controlled datapaths with autonomous addressing and instruction selection capability, a local data cache per data path, a shared memory with matrix type data access and a powerful DMA-unit. The proposed architecture was designed by assessing the results of an analysis of characteristic algorithm properties with respect to their inherent parallelization resources, achievable speed up and implementation costs. This resulted in a proper balance between the degree of parallelism and flexibility, leading to a high performance for a wide field of applications. Additional measures were taken to support an efficient high level programmability of the processor. This was achieved by the concurrent implementation of special architectural features and a C++-programming environment. It consists of an adaptation of the GNU C++-compiler and an optimizing assembler, supporting all levels of concurrence offered by the hardware. While most levels of parallelization are kept invisible to the programmer, data-level parallelism is expressed by the programmer using special new data types added to the standard C/C++-data-types. A sustained performance of about 2.0 Gigaoperations per second is achieved by the 100 MHz clocked processor for numerous image processing algorithms, leading to a processing time e.g. for a normalized correlation of a 512 × 512 image with a 32 × 32 correlation mask of 450 ms. Thus, a performance is achieved with a programmable parallel processor architecture that hitherto required the application of a dedicated integrated circuit. 相似文献
