As Web-related techniques and equipment grow, the Internet has become popular as a major channel for providing a wide variety of information. However, users face the serious problem of information overload when acquiring increasing amounts of information from the Internet. This problem is one of the most important issues in providing information services to meet users’ requirements in an electronic commerce environment. In this paper, we propose an information push-delivery system, which applies fuzzy information retrieval and fuzzy similarity measurement to avoid the information overload problem. This proposed system is helpful for users to acquire suitable information from the Internet. An empirical investigation of the proposed system is implemented in this study. The results show that the degree of satisfaction for the received information for all participants was as high as 71%, indicating that the proposed system can effectively provide correct and interesting information for users.  相似文献

The emergence of the new format of electronic/digital records provides the opportunity for archivists to reconsider the presumed format-neutrality of professional practice. As research in electronic records has served to re-emphasise, without an understanding of the needs and forms of material, then the work of archivists can have a profound impact on the evidential value and long-term research potential of the material. This paper attempts to broaden the debate about the requirements of all archival formats, and to build a new regime of 21st-century format specialists.

The present study examined the role of verbal working memory (memory span and tongue-twister), two-character Chinese pseudoword reading (two tasks), rapid automatized naming (RAN) (letters and numbers), and phonological segmentation (deletion of rimes and onsets) in inferential text comprehension in Chinese in 31 less competent comprehenders compared with 37 reading comprehension control students and 23 chronological age controls. It was hypothesized that the target students would perform poorly on these cognitive and linguistic tasks as compared with their controls. Furthermore, verbal working memory and pseudoword reading would explain a considerable amount of individual variation in Chinese text comprehension. RAN would have a nonsignificant role in text comprehension. Structural equation analyses and hierarchical multiple regression analyses generally upheld these hypotheses. Our findings support current literature of the role of verbal working memory in reading comprehension found in English. The results, however, suggest differential role of the constructs and the tasks in reading comprehension and provide some answers for comprehension impairment in Chinese students.  相似文献

As current graduate instructors of labs and class discussions, teaching assistants (TAs) play a critical role in Science, Technology, Engineering, and Math (STEM) undergraduate education, especially as some graduate students may choose a faculty career in the future. Because of the importance of TAs and their development as scholars and instructors, we sought to determine the most effective methods of preparing engineering TAs at two research universities. We compare the impact of a teaching orientation with one of four teaching development programmes (Pedagogy Course, Advanced Practice Teaching, Workshop Attendance with Written Reflection, or Mid-Semester Student Feedback with Written Reflection) on engineering TAs’ teaching efficacy and definitions of active learning. Results indicated that the Pedagogy Course consistently increased TAs’ teaching efficacy and attitudes toward teaching compared with the other programmes. We also found that stand-alone Mid-Semester Student Feedback with Written Reflection enhanced TAs’ efficacy for reflection and beliefs about teaching. We discuss implications for providing teaching development for graduate students and directions for future research.  相似文献

By the early 1980s, many life scientists had begun to maintain small collections of cryopreserved tissues for their own specific research purposes. It became apparent that these materials could be successfully reused as new techniques and research questions emerged. This realization led several American leaders in the field of systematic taxonomy (the science of biological classification) and conservation genetics to argue for the need to take stock of and coordinate these heterogeneous collections. Their strategy, which they called ‘planned hindsight,’ was meant to organize the present in a way that appeared to anticipate the needs of future scientists. In this paper I examine how the seemingly paradoxical strategy of ‘planned hindsight’ has functioned as a strategy for choreographing life, time, and value at two centralized biospecimen collections: The Frozen Zoo in Escondido, CA, USA, and the Ambrose Monell Cryo Collection at the American Museum of Natural History in New York City. I conclude that, in practice, ‘planned hindsight’ not only contributes to the endurance of frozen tissues but also preserves widely divergent speculative visions of the many different individuals involved with their creation, maintenance, and re-use.  相似文献

中国当代文学传播目前面临一种两难选择,即客观上迫切需要传播媒体的介入,但主观上又对最时新的网络媒体采取一种"半推半就"的态度;按照文学的审美性质,文学作品最忌讳功利性的行为,但市场经济对文学的冲击又使文学不得不"低声下气"。  相似文献

The relationship between inappropriate breast support and upper-extremity kinematics for female runners is unclear. The purpose of this study was to investigate the effect of breast support and breast pain on upper-extremity kinematics during running. Eleven female recreational runners with larger breasts (UK D and E cup) completed a 7 min 20 s treadmill run (2.58 m · s?1) in a high and low breast support condition. Multi-planar breast and upper-extremity kinematic data were captured in each breast support condition by eight infrared cameras for 30 s towards the end of the run. Breast pain was rated at the end of each treadmill run using a numeric analogue scale. The high support bra reduced breast kinematics and decreased breast pain (P < 0.05). Upper-extremity kinematics did not differ between breast support conditions (P > 0.05), although some moderate positive correlations were found between thorax range of motion and breast kinematics (r = 0.54 to 0.73). Thorax and arm kinematics do not appear to be influenced by breast support level in female runners with large breasts. A high support bra that offers good multi-planar breast support is recommended for female runners with larger breasts to reduce breast pain.  相似文献
