Online submission and peer‐review systems

We report on a research study commissioned by ALPSP into the current status of online submission and peer‐review systems, the perceptions of these by authors, referees and editors, and the impact of their introduction on journals.

Effect of postural changes on 3D joint angular velocity during starting block phase

Abstract

Few studies have focused on the effect of posture during sprint start. The aim of this study was to measure the effect of the modification of horizontal distance between the blocks during sprint start on three dimensional (3D) joint angular velocity. Nine trained sprinters started using three different starting positions (bunched, medium and elongated). They were equipped with 63 passive reflective markers, and an opto-electronic Motion Analysis® system was used to collect the 3D marker trajectories. During the pushing phase on the blocks, norm of the joint angular velocity (NJAV), 3D Euler angular velocity (EAV) and pushing time on the blocks were calculated. The results demonstrated that the decrease of the block spacing induces an opposite effect on the angular velocity of joints of the lower and the upper limbs. The NJAV of the upper limbs is greater in the bunched start, whereas the NJAV of the lower limbs is smaller. The modifications of NJAV were due to a combination of the movement of the joints in the different degrees of freedom. The medium start seems to be the best compromise because it leads, in a short pushing time, to a combination of optimal joint velocities for upper and lower segments.     

The Decline in Adult Activities Among U.S. Adolescents, 1976–2016

The social and historical contexts may influence the speed of development. In seven large, nationally representative surveys of U.S. adolescents 1976–2016 (N = 8.44 million, ages 13–19), fewer adolescents in recent years engaged in adult activities such as having sex, dating, drinking alcohol, working for pay, going out without their parents, and driving, suggesting a slow life strategy. Adult activities were less common when median income, life expectancy, college enrollment, and age at first birth were higher and family size and pathogen prevalence were lower, consistent with life history theory. The trends are unlikely to be due to homework and extracurricular time, which stayed steady or declined, and may or may not be linked to increased Internet use.     

Effects of Computerized Instruction on the Use of Punctuation Strategies by Students with LD

An interactive multimedia software program was developed for teaching punctuation strategies and then tested with middle‐school and high‐school students with learning disabilities. Students at each school level were randomly selected into an experimental or control group. Results showed that experimental students at both school levels performed similarly by earning significantly higher scores on a test of punctuation usage than the control students. Additionally, experimental students in both school cohorts inserted significantly fewer incorrect punctuation marks than the controls. Furthermore, the experimental students generalized their use of the strategies to a test where they wrote their own sentences. Thus, this study shows that students with LD can learn punctuation strategies at a high level of mastery and can generalize their skills to sentence editing and sentence construction tasks when taught through interactive multimedia.     

Turning the library upside down: Reorganization using total quality management principles

Professional staff at Samford University's Davis Library began to plan for vast organizational changes in the summer of 1990. This article describes their application of TQM principles to preparing for and implementing a restructuring of the Library and discusses the results of this reorganization.
