It is shown that a p+q node graph Gc representation can be drawn for a chessboard C(p,q) i.e. an array of p rows and q columns. It is shown further that the coefficients of the rook polynomial for C(p,q) correspond 1:1 inversely with the coefficients of the chromatic polynomial for Gc written in factorial form. 相似文献

Three groups of social bookmarking users, namely experienced users, users with moderate level of experience, and novice users, were investigated, in terms of their reported tagging behaviors, perceived usefulness of social bookmarking in information discovery and management, and perceived usefulness of the bookmarking features provided. Based on the empirical analysis of the Connotea users, who are primarily in academia, the study shows that experienced academic users generally prefer to use social bookmarking while moderately experienced and novice users still prefer to use the traditional bookmarking methods, such as creating and using bookmarks on a dedicated computer. Experienced academic users were also found to create more tags per bookmark comparing to the other two groups. Most novice academic users, however, only created one tag per bookmark, which just met Connotea's minimum requirement. Surprisingly different from the collaborative design nature of the social bookmarking systems, the study finds that our participants, particularly experienced academic users, prefer to create and use their own bookmarks rather than sharing bookmarks created by others. In fact, experienced users have significantly higher frequency (once every two weeks) of creating bookmarks than the other two groups (once a month or less). In addition, website design features and functions, such as automatic collection of bibliographic information, are regarded by all participants as helpful for information discovery. The in-depth examination and discussion of the opinions of Connotea users may be useful for further improvement of the design features and usage applications, particularly for academic social bookmarking websites. The results may also have potential implications to the future development of social bookmarking services in general. 相似文献

The purpose of this study was to examine the perceptions of African American faculty on their organizational socialization in kinesiology-based (i.e., sport pedagogy, exercise physiology, motor behavior, sport management/history) programs at predominantly White American institutions of higher education (PW-IHE). Participants were 9 African American tenure-track faculty members from various kinesiology-based programs at PW-IHE. Data were gathered via interviewing and analyzed within the framework of critical race theory (Ladson-Billings, 2000). Findings are presented using storytelling and thematic narratives. Interviews with the participants revealed four major recurring themes with regard to: (a) resources, opportunities, and power structures; (b) programmatic neglects and faculty mentoring needs; (c) social isolation, disengagement, and intellectual inferiority issues; and (d) double standards, marginalization, and scholarship biases. This study suggests that faculty and administrators at PW-IHE should develop sensitivity toward organizational socialization issues relevant to faculty of color. 相似文献

Changes have been occurring in the character of the present-day engineering product which require a review of the education for such engineering. A number of studies and reports have been made which seek to assess the needs and to suggest ideas for meeting the real challenge that exists. A separate study has been conducted by a group at the Case Institute of Technology along these same lines. This paper discusses the general educational problems and the broad philosophy which have been established to guide our subsequent curriculum development. The result is the need for a complete reappraisal of the existing curricula, with a degree of depth and integration among subject matter far beyond anything that has heretofore been attempted. 相似文献
