Essential Skills for Corporate and Special Librarians     

Rebecca Davis 《图书馆管理杂志》2020,60(7):762-783

Abstract

Library science programs must be responsive to the wide variety of workplace needs to ensure that graduating students are prepared with appropriate knowledge and skills regardless of where their career path brings them, and to do so they must understand the various needs and expectations of the field. Through a nationwide study of over 2,000 current professionals and LIS faculty, this study examines the knowledge, skills, and abilities identified as core for special and corporate librarians. The results help establish a baseline of skills for corporate and special librarians, which will be of interest to current and emerging professionals interested in a career in these settings and could have implications for LIS education.  相似文献   

Disaggregated Effects of Device on Score Comparability          下载免费PDF全文

Laurie Davis  Kristin Morrison  Xiaojing Kong  Yuanyuan McBride 《Educational Measurement》2017,36(3):35-45

The use of tablets for large‐scale testing programs has transitioned from concept to reality for many state testing programs. This study extended previous research on score comparability between tablets and computers with high school students to compare score distributions across devices for reading, math, and science and to evaluate device effects for gender and ethnicity subgroups. Results indicated no significant differences between tablets and computers for math and science. For reading, a small device effect favoring tablets was found for the middle to lower part of the score distribution. This effect seemed to be driven by increases in performance for male students when testing on tablets. No interactions of device with ethnicity were observed. Consistent with previous research, this study provides additional evidence for a relatively high degree of comparability between tablets and computers.  相似文献

Educating the educators: developing those who support learning for students with additional learning needs     

Benita McLachlan  Geraldine Davis 《Support for Learning》2013,28(4):173-180

This article reports findings from a research project which developed and introduced the Enhanced Learning Support Assistant Programme (ELSAP) as a source of professional development for learning support assistants who were supporting students with additional learning needs in a college of further education in England. The purpose of this article is to share findings from the project and to highlight the benefits experienced when learning support assistants can participate in professional development activity. The research project was a mixed methods study with participants drawn from learning support assistants within one college of further education in England. Data were collected throughout the 14‐week intervention. Findings indicate that the programme had a positive effect on participants' confidence, sense of professional identify and of being valued, as well as improving their ability to perform their role.  相似文献   

Rediscovering the Role of Interscholastic Sports     

William J. Davis 《The Educational forum》2013,77(2):122-132

The goals of today's school athletic programs are vastly different from the original intentions of the administrators who established the first interscholastic athletic teams. For athletics to be anything more than a drain on school and taxpayer resources, these programs must undergo serious changes.  相似文献

The influence of moment of inertia on baseball/softball bat swing speed   总被引：1，自引：1，他引：0

The speed at which a player can swing a bat is central to the games of baseball and softball, determining, to a large extent, the hit speed of the ball. Experimental and analytical studies of bat swing speed were conducted with particular emphasis on the influence of bat moment of inertia on swing speed. Two distinct sets of experiments measured the swing speed of colege baseball and fast-pitch softball players using weighted rods and modified bats. The swing targets included flexible targets, balls on a tee and machine pitched balls. Internal mass alterations provided a range of inertial properties. The average measured speeds, from 22 to 31 m s⁻¹, are consistent with previous studies. Bat speed approximately correlates with the moment of inertia of the bat about a vertical axis of rotation through the batter's body, the speed generally decreasing as this moment of inertia increases. The analytical model assumes pure rotation of the batter/bat system about a vertical axis through the batter's body. Aerodynamic drag of the batter's arms and the bat is included in the model. The independent variable is bat moment of inertia about the rotation axis. There is reasonable agreement between the model and the measured speeds. Detailed differences between the two suggest the importance of additional degrees of freedom in determining swing speed.  相似文献
