This case study examines patron record privacy and the Family Educational Rights and Privacy Act (FERPA) within a consortial environment. FERPA requirements were examined, as well as college and library policy and procedure. It was determined that information in library patron records is directory information and, under most circumstances, does not need FERPA protections. However, the needs of the confidential student, who requests confidentiality of all information, including directory information, were identified as not having been addressed. Reed Library adjusted policy and procedures to meet the needs of the confidential student and fulfill FERPA requirements. 相似文献

As an assignment for the Reference and User Services Association and as part of the American Library Association Emerging Leaders Program, the authors created a databank to house the results of a large-scale interlibrary loan staffing survey. After examining the pros and cons of several software solutions, the authors decided to use a Web-based database product, Dabble DB. The paper discusses the scope, outcomes, and value of the Reference and User Services Association interlibrary loan survey, the development of the authors’ project plan, and recommendations for the use of cloud-based database products in library operations. 相似文献

Curves are included showing the relationship between voltage and relative position of electrodes, and between voltage and counter gas pressure. Also included are experiments on the preparation of sensitive and insensitive points, and experiments with different electrode materials. These data are for a counter operated with the point at negative potential.Zeleny's conclusion that a high resistance layer of adsorbed gas exists at the point is adopted. In addition, the assumption is made that the field at the point at the onset of “self-counting” is sufficient to produce auto-electronic emission. This combination now leads to a theory which accounts for the various characteristics of the counter and explains the threshold of counting curve, the auto-counting curve, and the continuous discharge curve. Probability considerations account for the selective counting of different ionizing agents in certain voltage ranges, for the dependence of counting upon path of ionizing rays through the chamber, and for the increase of counts with increase of voltage from threshold of counting to the point where all rays are registered. 相似文献

Three examples of extant testing practices (i.e., a classroom instructor's use of a simple pre-post design, the practice of teaching to the test, and the think aloud verbal protocol) are discussed to illustrate the contention that assessment in the service of testing and learning does not necessarily involve radically different assessment practices. It is demonstrated that activities already familiar to teachers and assessment specialists can powerfully inform student learning and teaching practice. 相似文献

Increasing knee stability via appropriate muscle activation could reduce anterior cruciate ligament (ACL) injury risk during unplanned sidestepping. High-level athletes may activate their knee muscles differently from low-level athletes when responding to quasi-game realistic versus non game-realistic stimuli. Eleven high-level and 10 low-level soccer players responded to a non game-realistic arrow-planned condition (AP), a quasi game-realistic one-defender scenario (1DS) and two-defender scenario (2DS), and an arrow-unplanned condition (AUNP), that imposed increasing time constraints to sidestep. Activation from eight knee muscles during sidestepping was measured during pre-contact and weight-acceptance. Knee flexor-extensor co-activation ratios were established. Muscle activation levels increased by approximately 27% solely in the 1DS in both sidestepping phases. In the 2DS, the shift from a flexor dominant co-activation strategy in pre-contact toward extensor dominance in weight-acceptance commenced earlier for the high-level players. Quasi game-realistic information allowed for anticipatory increases in knee muscle activation regardless of expertise levels but only when the time demands to respond were low (1DS). High-level players were better at interpreting complex game-realistic information (2DS) to activate their knee extensors earlier in preparation for single-leg landing during weight-acceptance. 相似文献
