Mid-flight lateral trunk bending increased ipsilateral leg loading during landing: a center of mass analysis

Increased lateral trunk bending to the injured side has been observed when ACL injuries occur. The purpose was to quantify the effect of mid-flight lateral trunk bending on center of mass (COM) positions and subsequent landing mechanics during a jump-landing task. Forty-one recreational athletes performed a jump-landing task with or without mid-flight lateral trunk bending. When the left and right trunk bending conditions were compared with the no trunk bending condition, participants moved the COM of the upper body to the bending direction, while the COM of the pelvis, ipsilateral leg, and contralateral leg moved away from the bending direction relative to the whole body COM. Participants demonstrated increased peak vertical ground reaction forces (VGRF) and knee valgus and internal rotation angles at peak VGRF for the ipsilateral leg, but decreased peak VGRF and knee internal rotation angles at peak VGRF and increased knee varus angles at peak VGRF for the contralateral leg. Mid-flight lateral trunk resulted in an asymmetric landing pattern associated with increased ACL loading for the ipsilateral leg. The findings may help to understand altered trunk motion during ACL injury events and the discrepancy in ACL injuries related to limb dominance in badminton and volleyball.     

The NICE OECD countries' geographic search filters: Part 2—validation of the MEDLINE and Embase (Ovid) filters

Objective:We previously developed draft MEDLINE and Embase (Ovid) geographic search filters for Organisation for Economic Co-operation and Development (OECD) countries to assess their feasibility for finding evidence about the countries. Here, we describe the validation of these search filters.Methods:We identified OECD country references from thirty National Institute for Health and Care Excellence (NICE) guidelines to generate gold standard sets for MEDLINE (n=2,065) and Embase (n=2,023). We validated the filters by calculating their recall against these sets. We then applied the filters to existing search strategies for three OECD-focused NICE guideline reviews (NG103 on flu vaccination, NG140 on abortion care, and NG146 on workplace health) to calculate the filters'' impact on the number needed to read (NNR) of the searches.Results:The filters both achieved 99.95% recall against the gold standard sets. Both filters achieved 100% recall for the three NICE guideline reviews. The MEDLINE filter reduced NNR from 256 to 232 for the NG103 review, from 38 to 27 for the NG140 review, and from 631 to 591 for the NG146 review. The Embase filter reduced NNR from 373 to 341 for the NG103 review, from 101 to 76 for the NG140 review, and from 989 to 925 for the NG146 review.Conclusion:The NICE OECD countries'' search filters are the first validated filters for the countries. They can save time for research topics about OECD countries by finding the majority of evidence about OECD countries while reducing search result volumes in comparison to no filter use.     

The structure of research methodology competency in higher education and the role of teaching teams and course temporal distance

The development of research methodology competency is a major aim of the psychology curriculum at universities. Usually, three courses concentrating on basic statistics, advanced statistics and experimental methods, respectively, serve the achievement of this aim. However, this traditional curriculum-based course structure gives rise to the question whether an integrative research methodology competency is actually achieved or whether independent course-specific sub-competencies are established instead. To find out whether the course structure is favourable for the development of research methodology competency, items representing the contents of the three courses were applied to a sample of university students. Content validity was assured by a close relationship of the items with course contents and course tests. The investigation revealed a three-dimensional first-order structure in combination with a common second-order dimension. Differences between teaching teams and course temporal distance showed to have no influence.     

Judah L. Magnes and the Hebrew University

The horror of genocide in the twentieth century must be faced and must be told so that students of all races and religions understand the danger facing all peoples when human rights are denied to any one people. The Holocaust is a Jewish tragedy to be sure, but it not only that. It is a human tragedy, one which involves us all, whether directly or indirectly. It was not a phenomenon occurring long ago in a backward and primitive corner of the world. It occurred during the lifetime of millions still living and in a technologically and culturally advanced part of the world. Both the victims and the perpetrators sprang from groups that have contributed massively to the arts and sciences and to the uplifting of the human spirit. And yet, the Holocaust casts an ominous shadow over our civilization, as so it should, and as so it will until the end of time.     

From access to quality: migrant children’s education in urban China

An increasing number of migrant children are involved in public education due largely to the policy for migrant children education outlined by the Government of China from the late 1990s. In this article, we describe the unique and often difficult situation rural migrant children face after they enter urban public schools. Drawing from the Theory of Inclusive Education and data collected at two public junior high schools in Beijing, we provide an in-depth analysis on migrant children’s education from their own viewpoint and from the perspectives of their parents, teachers, and school administrators. Our survey results identify the need for further adjustments of the existing education system which can help improve migrant children’s education in China. Findings also highlight the dilemmas regarding how to best meet the needs for teachers, migrant parents, and migrant children who attend public schools. In order to provide a quality education for migrant children, we conclude by arguing that there must be a three-pronged partnership to best accommodate the unique education needs of migrant children in urban China.     

History of teaching anatomy in India: From ancient to modern times

Safe clinical practice is based on a sound knowledge of the structure and function of the human body. Thus, knowledge of anatomy has been an essential tool in the practice of healthcare throughout the ages. The history of anatomy in India traces from the Paleolithic Age to the Indus Valley Civilization, the Vedic Times, the Islamic Dynasties, the modern Colonial Period, and finally to Independent India. The course of the study of anatomy, despite accompanying controversies and periods of latencies, has been fascinating. This review takes the reader through various periods of Indian medicine and the role of anatomy in the field of medical practice. It also provides a peek into the modern system of pedagogy in anatomical sciences in India. Anat Sci Educ 6: 351–358. © 2013 American Association of Anatomists.     

The LINDSAY Virtual Human Project: An immersive approach to anatomy and physiology

The increasing number of digital anatomy teaching software packages challenges anatomy educators on how to best integrate these tools for teaching and learning. Realistically, there exists a complex interplay of design, implementation, politics, and learning needs in the development and integration of software for education, each of which may be further amplified by the somewhat siloed roles of programmers, faculty, and students. LINDSAY Presenter is newly designed software that permits faculty and students to model and manipulate three‐dimensional anatomy presentations and images, while including embedded quizzes, links, and text‐based content. A validated tool measuring impact across pedagogy, resources, interactivity, freedom, granularity, and factors outside the immediate learning event was used in conjunction with observation, field notes, and focus groups to critically examine the impact of attitudes and perceptions of all stakeholders in the early implementation of LINDSAY Presenter before and after a three‐week trial period with the software. Results demonstrate that external, personal media usage, along with students' awareness of the need to apply anatomy to clinical professional situations drove expectations of LINDSAY Presenter. A focus on the software over learning, which can be expected during initial orientation, surprisingly remained after three weeks of use. The time‐intensive investment required to create learning content is a detractor from user‐generated content and may reflect the consumption nature of other forms of digital learning. Early excitement over new technologies needs to be tempered with clear understanding of what learning is afforded, and how these constructively support future application and integration into professional practice.

Verbal Final Exam in Introductory Biology Yields Gains in Student Content Knowledge and Longitudinal Performance

We studied gains in student learning over eight semesters in which an introductory biology course curriculum was changed to include optional verbal final exams (VFs). Students could opt to demonstrate their mastery of course material via structured oral exams with the professor. In a quantitative assessment of cell biology content knowledge, students who passed the VF outscored their peers on the medical assessment test (MAT), an exam built with 40 Medical College Admissions Test (MCAT) questions (66.4% [n = 160] and 62% [n = 285], respectively; p < 0.001);. The higher-achieving students performed better on MCAT questions in all topic categories tested; the greatest gain occurred on the topic of cellular respiration. Because the VF focused on a conceptually parallel topic, photosynthesis, there may have been authentic knowledge transfer. In longitudinal tracking studies, passing the VF also correlated with higher performance in a range of upper-level science courses, with greatest significance in physiology, biochemistry, and organic chemistry. Participation had a wide range but not equal representation in academic standing, gender, and ethnicity. Yet students nearly unanimously (92%) valued the option. Our findings suggest oral exams at the introductory level may allow instructors to assess and aid students striving to achieve higher-level learning.
