In Color
No full textIn Color is a collection of shorts, poems, and essays in which the author explores her identity, as well as her past experience and imagined future. While the document consists chiefly of nonfiction, the narratives contained within are based on faulty memory and the author’s imagination, and therefore, like all nonfiction, are purely speculative. The author presents a cohesive document in which form and content are hybrid in nature to reflect the impossibility of neat categorization, and the impossibility of cataloguing identity, which she has nonetheless attempted to do. In many ways, this collection is a failure. It could be no other way
The Natural Mother of the Child
Get PDFThe Natural Mother of the Child is a memoir-in-essays about Belc’s experiences as a transmasculine birth parent. These essays use text and images to explore parenting on the margins of both motherhood and fatherhood. They also examine the ways in which legal and identity documents are limiting in their ability to describe gender and family. Topics explored include pregnancy, birth, lactation, masculinity, top surgery, medical transition, the meaning of biological relationships between parents and children, and microaggressions against transgender people
UNDERSTANDING NEGLECT OF PLANT BIOLOGY EDUCATION IN MICHIGAN MIDDLE SCHOOLS
Get PDFThe purpose of this study was to identify historical trends of neglect in plant biology education, their continuation today in Michigan middle school classrooms, and to uncover reasons for this neglect. A content analysis of state and national science standards and an online survey of Michigan middle school life science teachers were conducted. Findings showed a trend of increasing references in national standards from animals or plants to general organisms, as well as a decrease in the overall number of specific references in the standards. The data also revealed that nearly half of the teachers surveyed spent less than ten percent of their life science class time on plants, indicating ongoing levels of plant neglect in middle school classrooms. Overall, the findings indicated providing teachers and students with direct experience growing, observing and having guided explorations with plants could increase their intrinsic and long-term interest in and understanding of plants. This approach would build upon constructivist theory of learners, including teachers and students alike, having need for baseline experiences upon which to develop and grow. Given the critical role plants play in the biosphere, in the functioning of human lives and in the increasing trend of consumer interest in plants, addressing identified levels of plant neglect and working towards building botanical capacity in school classrooms could be of benefit to the human race and support of healthy life on earth
THE NEXT STEPS FOR EXPANDING AND DEEPENING SPORT BIOMECHANICS
Get PDFStarting with introduction of the activities of biomechanics research projects of JAAF in which I was involved, how we conducted feedback of sport biomechanics data to athletes and coaches will be described. I will share ideas to find solutions to some long-standing questions in sport biomechanics and in the field, and to further expand and deepen sport biomechanics. Topics are learning from skilled athletes, exchanging basic and practical biomechanics, i.e. sport biomechanics，expanding sport biomechanics to practice in the field
RELATIONSHIPS BETWEEN MOTION OF THE SHOULDER JOINT AND THE MAXIMAL HEIGHT OF VAULTERS’ CENTRE OF GRAVITY
Get PDFThe purpose of this study was to clarify the effect of the shoulder joint motion during vaulting on the maximal height of vaulters‘ centre of gravity (CGv). Eight male vaulters (personal best record: 4 m 60 to 5 m 77) vaulted over a cross bar with run-ups and pole in the same set up as competitions. Three-dimensional coordinates of the body were collected using a motion capture system (250 Hz). The angular displacement of the shoulder joint on the lower grip side between take-off and swing and on the upper grip side between rock back and pole straight showed high correlations with the maximal height of the CGv (r = 0.78 and -0.91, respectively). These results suggest that the shoulder joint motions because this motion could make it easy for vaulters and poles to rotate around the lower tip and possible for them to receive the recoil force of the poles effectively
DIFFERENT MOVEMENT TASK STRATEGIES DURING UNANTICIPATED CUTTING MANOEUVRES – PILOT STUDY
Get PDFThe aim of this study was to describe different movement task strategies during unanticipated cutting manoeuvres based on initial foot contact and angle in the frontal plane at the instant of first contact with the ground. Four female athletes participated in this study. Nine infrared cameras and force platform were employed to collect the kinematic and kinetic data. Athletes used four different movement task strategies during unanticipated cutting manoeuvres (45°) in initial contact with the ground. The results of this pilot study showed that combination of rearfoot strike and knee valgus angle position at the initial contact may increase the risk of an ACL injury
LIMIT CYCLE DYNAMICS ACROSS ELITE MALE ARTISTIC GYMNASTS
Get PDFBiological systems described by their attractor dynamics provide a method to understand the fundamental characteristics of skilled movement. Here the limit cycle dynamics of the longswing were investigated across tiers of elite men’s gymnasts. Senior, junior and development elite gymnasts (N=21) performed three trials of eight consecutive longswings on high bar. Limit cycle analysis revealed a more symmetrical angular velocity of the centre of mass about the bar trajectory in phase space, higher recurrence, lower correlation dimension and lower variability for senior gymnasts suggesting a more deterministic, efficient and predictive technique. The addition of non-linear dynamics to traditional biomechanics offers complementary theoretical and coaching knowledge to movement coordination, control and skill
THE RELATIONSHIPS AMONG GAIT PARAMETERS AND SENIOR FITNESS VARIABLES IN EXPLAINING SENIOR FUNCTIONAL ABILITY OF KOREAN ELDERLY PEOPLE
Get PDFThe purpose of this study was to investigate the relationships among gait parameters and senior fitness variables in explaining the fitness ability of senior people. Two hundreds elderly people aged 65 to 85 participated in this study and they performed level walking at different speeds, senor fitness test, and composition measures. Among 33 measured parameters, principal component analysis (PCA) revealed five PCs such as gait characteristics, physical featue, gait variability, and fitness levels. In addition, the correlation analysis showed a fitness score is closely associated with single support time, walking speed, step and stride lengths, and flexibility of upper arms. In conclusion, gait parameters would a moderate indicator explaining health condition of elderly peopl
COMPARING AN INERTIAL SENSOR SYSTEM TO VIDEO FOR ACL INJURY RISK SCREENING
Get PDFQuantifying landing technique in sport-specific environments is desirable for effective injury prevention programs. The aim of this study was to compare an inertial sensor (Xsens) with high-speed cameras during landing. Ten participants performed double and single-leg drop vertical jumps while data from both systems were collected. Joint angle and excursion from Xsens was compared with the high-speed video. Bland and Altman plots and root mean of the squared difference quantified validity. Larger values of knee valgus excursion was reported with Xsens by 0.4-0.7cm. Additionally, Xsens overreported most joint flexion. Although an inertial sensor system may provide valuable information of landing kinematics in an applied environment, the resultant data must be carefully examined prior to drawing conclusions regarding the ACL injury risk of the athlete
