Skiing‐Skating

An articulated boot design is commonly used in skiing and skating sports because it allows sagittal plane ankle mobility while still providing critical frontal plane stability. Although articulated boots have been in use for several decades, current manufacturers of these boots differ in their articulation placement. In this study we determined an optimal position of the ankle articulation axis. We also calculated the amount of anterior skin movement that a boot tongue must account for during a full range of ankle motion. Three‐dimensional kinematic data were collected and analyzed from 40 participants moving their right foot through a full range of sagittal plane motion. The calculated horizontal position of the articulation axis was found to be highly predictable from foot length (r = 0.87, standard error of estimate = 3.44 mm), while its vertical component displayed less predictability (r = 0.49, standard error of estimate = 7.46 mm). The expansion required by the boot tongue had a moderate association with foot length and low variability (r = 0.58, standard error of estimate = 0.07 mm). An accurate axis placement will minimize relative motion between the boot cuff and the ankle, reducing friction and motion resistance. An expandable tongue will accommodate full plantar flexion and reduce pressure on the anterior ankle during dorsiflexion, eliminating common pressure‐related injuries.     

A simple microscopy assay to teach the processes of phagocytosis and exocytosis

Phagocytosis and exocytosis are two cellular processes involving membrane dynamics. While it is easy to understand the purpose of these processes, it can be extremely difficult for students to comprehend the actual mechanisms. As membrane dynamics play a significant role in many cellular processes ranging from cell signaling to cell division to organelle renewal and maintenance, we felt that we needed to do a better job of teaching these types of processes. Thus, we developed a classroom-based protocol to simultaneously study phagocytosis and exocytosis in Tetrahymena pyriformis. In this paper, we present our results demonstrating that our undergraduate classroom experiment delivers results comparable with those acquired in a professional research laboratory. In addition, students performing the experiment do learn the mechanisms of phagocytosis and exocytosis. Finally, we demonstrate a mathematical exercise to help the students apply their data to the cell. Ultimately, this assay sets the stage for future inquiry-based experiments, in which the students develop their own experimental questions and delve deeper into the mechanisms of phagocytosis and exocytosis.     

Using Kinesthetic Activities to Teach Ptolemaic and Copernican Retrograde Motion

This paper describes a method for teaching planetary retrograde motion, and the Ptolemaic and Copernican accounts of retrograde motion, by means of a series kinesthetic learning activities (KLAs). In the KLAs described, the students literally walk through the motions of the planets in both systems. A retrospective statistical analysis shows that students who participated in these activities performed better on examination questions pertaining to retrograde motion than students who did not. Potential explanations for this result, including the breaking of classroom routine, the effect of body movement on conceptual memory, and egocentric spatial proprioception, are considered.

Evolution and Diffusion of the Michigan State University Tradition of Organizational Communication Network Research

This article documents the 30‐year history of communication network research at Michigan State University (M.S.U.), providing a case study of the evolution and diffusion of an academic innovation. Three past and continuing issues for network scholars are identified: a lack of professional reward for developing user‐friendly computer programs, unresolved methodological problems, and a need for better theoretical and conceptual frameworks. The narrative also illustrates the difficulty communication as a discipline has in impacting broader intellectual traditions. The story begins with the first doctoral dissertation (Schwartz, 1968 Richards, W. D. and Barnett, G., eds. 1993. Progress in communication sciences: Advances in communication network analysis, Norwood, NJ: Ablex.  [Google Scholar]) and the first network analysis software program in 1970 (Richards’ Negopy), continuing to the last dissertation (Susskind, 1996 Susskind, A. M. 1996. The impact of an organizational downsizing effort on survivors’ communication network relationships and attitudes, East Lansing: Department of Communication, Michigan State University. Unpublished doctoral dissertation [Google Scholar]), and ending in 1998 when J. David Johnson left the M.S.U. faculty. Other major players in the M.S.U. network tradition included David K. Berlo, Eugene Jacobson, Everett M. Rogers, Vincent Farace, Peter Monge, and Erwin Bettinghaus. Ironically, Schwartz and Susskind met in 1998 while Schwartz was preparing to retire from Cornell University and Susskind was starting as an Assistant Professor in a different department, thus providing closure to the M.S.U. network.     

A Cross-Cultural Analysis of Organizational Dissent and Workplace Freedom in Five European Economies

Individuals in five European countries—Finland, France, Germany, Spain, and the United Kingdom (n = 1184)—completed a survey exploring the relationship between organizational dissent and workplace freedom of speech. Results revealed workplace freedom of speech is positively correlated with dissent among the entire sample in France and in Germany. Results in Spain were nonsignificant. In the United Kingdom, there was a negative relationship between workplace freedom of speech and dissent. There was a negative relationship between workplace freedom of speech and articulated dissent and a positive relationship with latent dissent in Finland. Moreover, MANCOVA testing showed nationality to have a significant effect on organizational dissent and workplace freedom of speech. Germans scored the highest on dissent and workplace freedom with Spain scoring the lowest.     

Radical Relocation: Adapting Print Collections to an E-Centric World

With the advent of e-journal preservation projects and publisher digitization of journal backfiles, academic libraries have begun to move their corresponding print volumes of these titles to storage to avoid duplication and save space. This article examines the supporting justifications, outreach mechanisms, and logistical procedures undertaken at American University Library to relocate the entire bound journal collection to offsite storage in order to address severe physical space constraints and to support patron use of and preference for electronic journal content. In addition, the article presents preliminary data regarding the use of bound volumes sent to storage and an overall analysis of this transformational project.     

Escaping the subject-based class: A Finnish case study of developing transversal competencies in a transdisciplinary course

Abstract

In 2014, the Finnish National Board of Education launched a new core curriculum with the aim of meeting the skills and competence requirements of the 21st century. The purpose of this case study was to find out what transversal competencies Finnish eighth graders developed and how they experienced studying in a problem-based transdisciplinary course, which was arranged for the transitional stage between the former and the new curriculum. The qualitative data consisted of questionnaires and interviews. The analysis followed the methods of qualitative content analysis. When asked about their learning, the students commented on not having learnt much, referring to the discipline-based knowledge. Instead, they had learnt skills through teamwork, problem solving, and expression of their views and opinions, an aspect that they did not clearly connect with the things to be learnt at school. Many students felt that they acquired the competencies that they would need later in their lives. The students’ teamwork had a crucial impact on their learning experience. The timeframe for the integrative approach needs careful consideration; the learning process in this course was perceived as being successful because it was long enough. Our study highlights that focusing on students’ views is critical when reforming curriculum.
