The standard error of measurement (SEM) is the standard deviation of errors of measurement that are associated with test scores from a particular group of examinees. When used to calculate confidence bands around obtained test scores, it can be helpful in expressing the unreliability of individual test scores in an understandable way. Score bands can also be used to interpret intraindividual and interindividual score differences. Interpreters should be wary of over-interpretation when using approximations for correctly calculated score bands. It is recommended that SEMs at various score levels be used in calculating score bands rather than a single SEM value. 相似文献

This case study presents the development and implementation of a personal librarian program for a cohort-based, executive-style higher education administration doctoral program. Librarians and the program director collaborated to create a student-centered program based on individual research needs. The personal librarian program was designed to build a close relationship between the librarian and individual students; to help identify their research knowledge gaps; and to identify resources to meet each individual students' research needs. 相似文献

Starting from the notion of h-type indices for infinite sequences we investigate if these indices satisfy natural inequalities related to the arithmetic, the geometric and the harmonic mean. If f denotes an h-type index, such as the h- or the g-index, then we investigate inequalities such as min(f(X),f(Y)) ≤ f((X?+?Y)/2) ≤ max(f(X), f(Y)). We further investigate if: f(min(X,Y)) = min(f(X),f(Y)) and if f(max(X,Y)) = max(f(X),f(Y)). It is shown that the h-index satisfies all the equalities and inequalities we investigate but the g-index does not always, while it is always possible to find a counterexample involving the R-index. This shows that the h-index enjoys a number of interesting mathematical properties as an operator in the partially ordered positive cone (R+)∞ of all infinite sequences with non-negative real values.In a second part we consider decreasing vectors X and Y with components at most at distance d. Denoting by D the constant sequence (d,d,d, …) and by Y-D the vector (max(yr-d), 0)r, we prove that under certain natural conditions, the double inequality h(Y-D) ≤ h(X) ≤ h(Y?+?D) holds. 相似文献

Lincoln Memorial University‐DeBusk College of Osteopathic Medicine (LMU‐DCOM) offers an optional three‐week summer Anatomy Boot Camp course (ABC) to facilitate students' transition into medical school and promote retention of anatomy subject matter. The pre‐matriculation program is a supplemental instruction course that utilizes a small group learning format. Boot camp instruction is led by teaching assistants and two anatomy professors. Enrollees gain early exposure to Medical Gross Anatomy (MGA) course subject matter, which is taught in the fall semester, and learn study skills necessary to excel in medical school. No grade is assigned for the course, therefore participants can study without the fear of potentially affecting grades. This study evaluates the effectiveness of the LMU‐DCOM ABC course using data from four consecutive summers. Independent two‐sample t‐tests were used to compare ABC to non‐ABC students for the following variables: incoming grade point average (GPA) and Medical College Admission Test® (MCAT®) scores, MGA written and laboratory practical examination grades, and final MGA course grade. Additionally, a 26‐question survey was administered to 2012–2014 boot camp participants. There were no significant differences in incoming GPA and MCAT scores. However, boot campers scored significantly higher on the first two lecture and laboratory examinations (P < 0.05) for each year of the study. Thereafter scores varied less, suggesting a faster head start for boot camp participants. Mean MGA final grade was on average 3% higher for the boot camp cohort. The survey feedback supports that the ABC course assists with the academic and social transition into medical school. Anat Sci Educ 10: 215–223. © 2016 American Association of Anatomists. 相似文献

Conclusion Convergence is a very exciting model and one that holds, unforeseen opportunities. However in the current economic environment,
the investment community is hesitant to recommend that communications companies devote many resources in that area. The convergence
mode must prove that it can generate revenue and profits. Yet, it is limited to an advertising-supported model—a part of the
communications industry that has struggled during the past, year due to the recession. The increased advertising revenue that
would be generated by the convergence model is tainted—most likely taking advertising share away from the traditional media
segments that are supporting the model. Tied to the convergence model is a high dependency on the Internet. Internet advertising
is not local. In addition, financial data clearly illustrates that the Internet has caused profit margins to decrease substantially,
something that the traditional media company supporting the convergence model can not allow to happen. Finally, FCC deregulation
with regards to television station cap restrictions, cable system operators owning broadcasters in the same market, and cross
ownership of newspapers and television stations in the same market, will most likely have a negative impact on the convergence
model.
If a communications company should decide to go forward with convergence, there are five rules that should be followed:
The essay is based on a presentation made by Dr. Kivijarv at convergece: The Tour, a four-day conference sponsored by The American Press Institute. The purpose of the conference is to analyze the various
issues that communications companies should consider before attempting to build multimedia news operations that consolidate
newspaper, television, wired cable, and/or Internet divisions in a specific market. Dr. Kivijarv's presentation occurred on
the final day of the conference and spoke to the investment community's financial concerns. Veronis Suhler Stevenson publishes,
two of the leading annual reports on the communications industry—the Communications Industry Forecast and the Communications Industry Report. A majority of the data used in the presentation and this essay come from those reports and Dr. Kivijarv, as the Director
of Research & Publications at Veronis Suhler Stevenson, serves as the editor of the two reports. 相似文献
