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

Purpose
Metalloproteinases are a key component of the pathogenesis of abdominal hernias. Obesity is considered a risk factor in herniogenesis and hernia recurrence. The aim of this study was to evaluate the serum concentrations of metalloproteinase-2 (MMP-2), MMP-9, MMP-13, and adiponectin in morbidly obese and nonoverweight controls.Materials and methods
The participants were recruited from among patients undergoing bariatric and non-bariatric surgery and divided into two groups: I (body mass index (BMI)≥35 kg/m2, n=40) and II (BMI<25 kg/m2, n=30). Serum concentrations of MMP-2, MMP-9, MMP-13, and adiponectin were measured using enzyme-linked immunosorbent assay (ELISA).Results
A statistically significant difference between groups was observed for MMP-2 concentration. The median MMP-9 concentration was higher in the obese group, but the difference was not statistically significant. Median MMP-13 concentrations did not differ between groups. Serum adiponectin concentration was insignificantly higher in the non-obese group.Conclusions
The elevated serum MMP-2 and MMP-9 concentrations in obese individuals may be related to the higher incidence of incisional hernias in this population.5.

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

The article forms an analysis of the religious discrimination discourse in Polish public schools, with special attention paid to the culturally specific, Polish understanding of the notion of religious discrimination. The introductory part presents the concept of religious discrimination as present in anti-discriminatory policies. The following part outlines the Polish system of religious education and its relation to the religious discrimination. Studies on religious discrimination in Poland are presented and discussed. Important context is supplied by a presentation of two recent cases of religious discrimination in Polish public schools, and the actions undertaken by the Freedom from Religion Foundation. Authors of the article point out the important influence of cultural context on the perception of religious discrimination. The attention is drawn to the seemingly homogenous environment of the Polish school and of the discriminative discourse used in political and social debates. The analysis shows that the presence of religion as a subject in Polish schools remains a cause of conflict between the religious and atheist citizens, a conflict in which concepts of religious discrimination and religious freedom are used as arguments by both sides. 相似文献

There is no need nowadays to convince people that modern education cannot function properly without the help of scientific research, and especially of pedagogical research. It is true that there still appear many pedagogical works inflated by wind, as Comenius expressed it more than three hundred years ago, and these publications may even acquire a temporary popularity. But the general trend towards the development of pedagogy as a discipline based on research has been established for quite some time and is constantly gaining strength in the developed countries. Concurrently, pedagogical disciplines have had increasing influence on the development of education.The question of how these disciplines have developed in Poland and how they have influenced the educational system calls for a broader review, such as to allow one to draw conclusions on how to harmonise more effectively the domain of educational research with that of education. Such a review is the aim of the present paper. The following issues are considered: the functions of educational research, the kinds of educational investigations conducted in Poland, ways of disseminating their findings, and the organisation of research in Poland. The paper ends with a discussion of some of the more important conclusions reached.
Zusammenfassung Heutzutage ist es nicht mehr nötig, viele Worte darüber zu verlieren, daß ein modernes Bildungswesen ohne Unterstützung durch wissenschaftliche, insbesondere pädagogische Forschung nicht richtig funktionieren kann. Zwar erscheinen immer noch viele pädagogische Arbeiten, die vom Wind aufgeblasen sind, wie sich Comenius vor über 300 Jahren ausdrückte, und diese können sogar zeitweilig grossen Anklang finden. Aber der allgemeine Trend, die Pädagogik als eine auf Forschung beruhende Disziplin anzusehen, besteht seit längerer Zeit und verstärkt sich in den Industrieländern ständig. Gleichzeitig üben pädagogische Disziplinen zunehmenden Einfluß auf die Entwicklung des Bildungswesens aus.Die Frage, wie sich diese Disziplinen in Polen entwickelt und wie sie das Bildungssystem beeinflußt haben, erfordert eine umfassendere Übersicht, die es ermöglicht, Schlußfolgerungen darüber zu ziehen, wie die pädagogische Forschung am besten mit dem Bildungswesen harmonisiert werden kann. Eine solche übersicht versucht der vorliegende Artikel zu geben. Er behandelt die folgenden Themen: die Funktionen der pädagogischen Forschung; die Art der in Polen angestellten Untersuchungen; die Verbreitungsmöglichkeiten ihrer Ergebnisse; und die Organisation der Forschung in Polen. Abschließend werden einige der wichtigeren Schlußfolgerungen besprochen.
Résumé De nos jours il n'est plus nécessaire de convaincre les gens que l'éducation moderne ne peut fonctionner de façon satisfaisante sans l'aide de la recherche scientifique, et plus spécialement de la recherche pédagogique. Il est vrai que l'on voit encore paraître de nombreux ouvrages pédagogiques gonflés de vent comme le disait déjà Comenius il y a plus de trois siècles, et ces publications peuvent éventuellement connaître une popularité passagère. Mais le courant général selon lequel la pédagogie est une discipline en developpement basée sur la recherche est désormais irréversible et il prend sans cesse plus d'importance dans les pays développés. Concurrement, les disciplines pédagogiques exercent une influence croissante sur le développement de l'éducation.Comment ces disciplines se sont-elles développées en Pologne et comment y ontelles influencé le système de l'éducation, sont deux questions qui demandent une étude approfondie si l'on veut en tirer des conclusions permettant d'harmoniser plus efficacement le domaine de la recherche en éducation et celui de l'éducation. C'est là l'objet de cet article. L'auteur considère les fonctions de la recherche en éducation, les différentes sortes d'enquêtes éducationnelles menées en Pologne, les moyens de diffusion des résultats et l'organisation de la recherche dans ce pays. Il termine par une discussion des conclusions les plus importantes auxquelles les Polonais sont parvenus.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
