Revisiting a study performed 30 years ago, researchers at three institutions surveyed undergraduate and graduate students in marketing courses to determine their attitudes toward and knowledge of library services and collections. Results found that 21st-century students are more likely to believe in the importance of library research, to have had library instruction, and to use Web sites and Internet search engines to begin their research. However, they are less likely to read business periodicals. Faced with a list of information sources, they are generally able to pick out a useful resource, although not always the most efficient. Implications for library service to business students are discussed. 相似文献

Stereo camera systems have been used to track markers attached to a racket, allowing its position to be obtained in three-dimensional (3D) space. Typically, markers are manually selected on the image plane, but this can be time-consuming. A markerless system based on one stationary camera estimating 3D racket position data is desirable for research and play. The markerless method presented in this paper relies on a set of racket silhouette views in a common reference frame captured with a calibrated camera and a silhouette of a racket captured with a camera whose relative pose is outside the common reference frame. The aim of this paper is to provide validation of these single view fitting techniques to estimate the pose of a tennis racket. This includes the development of a calibration method to provide the relative pose of a stationary camera with respect to a racket. Mean static racket position was reconstructed to within ±2 mm. Computer generated camera poses and silhouette views of a full size racket model were used to demonstrate the potential of the method to estimate 3D racket position during a simplified serve scenario. From a camera distance of 14 m, 3D racket position was estimated providing a spatial accuracy of 1.9 ± 0.14 mm, similar to recent 3D video marker tracking studies of tennis. 相似文献

A Class Performance System (CPS) is applied as an assessment tool to assist in determining the level of information literacy knowledge already possessed by adult students enrolled in a graduate Educational Leadership and Technology program. The CPS data collected reveals that students possess varying degrees of technology expertise and information literacy skills. Study results suggest that clickers facilitate differentiated information literacy pedagogy and increase engagement for graduate students. 相似文献

In the light of predictions of future protein shortages the non-agricultural routes to protein production have become an industrial reality. These routes are based on the continuous fermentation of micro-organisms to produce single cell proteins. Seen as only a long-term possibility a few years ago, many commercial enterprises now have successful SCP production facilities, while research and development in this field continues at a rapid pace. 相似文献

本研究试图通过分析高考英语完形填空数据和考试者的心理过程来探讨干扰项如何通过文段的语境来干扰考试者的考试行为。研究发现,不同类型的干扰项对考试者的干扰程度不尽相同,它们对考生做题过程中启动的信息处理机制的影响也不完全相同。在研究结果基础上,作者对考试策略、教学以及出题方法提出了建议。 相似文献
