The influence of water depth on kinematic and spatiotemporal gait parameters during aquatic treadmill walking

The purpose of this study was to investigate kinematic and spatiotemporal variables of aquatic treadmill walking at three different water depths. A total of 15 healthy individuals completed three two-minute walking trials at three different water depths. The aquatic treadmill walking was conducted at waist-depth, chest-depth and neck-depth, while a customised 3-D underwater motion analysis system captured their walking. Each participant’s self-selected walking speed at the waist level was used as a reference speed, which was applied to the remaining two test conditions. A repeated measures ANOVA showed statistically significant differences among the three walking conditions in stride length, cadence, peak hip extension, hip range of motion (ROM), peak ankle plantar flexion and ankle ROM (All p values < 0.05). The participants walked with increased stride length and decreased cadence during neck level as compared to waist and chest level. They also showed increased ankle ROM and decreased hip ROM as the water depth rose from waist and chest to the neck level. However, our study found no significant difference between waist and chest level water in all variables. Hydrodynamics, such as buoyancy and drag force, in response to changes in water depths, can affect gait patterns during aquatic treadmill walking.  相似文献   

The education of academically gifted students in South Korea: Innovative approaches in shadow education     

Young Chun Kim  Jaeseong Jo  Jung-Hoon Jung 《European Journal of Education》2020,55(3):376-387

Shadow education contributes to the learning and academic careers of Korean students. It benefits, in particular, gifted students who are strongly motivated and who outperform their peers academically. In this study, we explored the innovative characteristics of shadow education curricula for gifted students in terms of curricular programmes, methods, and teaching-learning materials. Also, we explored how shadow education practices meet the academic abilities and needs of students. Informed by a literature review and qualitative research methods, the results reveal how common shadow education is; effects of shadow education; and innovative elements used in shadow education for gifted students in Korea. Overall, we found that shadow education plays a crucial role in gifted education; it is a necessary component for understanding academic excellence among students in Korea. The findings are helpful for teachers, curriculum developers, and policymakers as they explore how public schooling can help to support strongly motivated and academically advanced students.  相似文献   

Platform War vs. Platform Synergy? A Longitudinal Analysis of Media Substitution between Personal Computers and Mobile Devices     

Su Jung Kim  Vijay Viswanathan  Hye Mi Lee 《广播与电子媒介杂志》2020,64(2):65-88

ABSTRACT

Research on media substitution theory has examined substitutional and/or complementary relationships between new and existing media. This study focuses on the growth of mobile platforms and investigates the relationship between mobile devices and personal computers. Using Nielsen’s panel data that provide electronically recorded media usage (N = 2,396), this study analyzes yearly changes in time allocation to mobile devices and PCs at total and content-specific usage levels during mobile 4G transition. Results suggest a complementarity dynamic between mobile devices and PCs; however, the patterns were more nuanced in light of the role of individual and structural factors when determining media choice.  相似文献   

欧洲九国共产党情报局机关刊物《争取持久和平,争取人民民主!》与中国关系考述(1949-1956)     

哈战荣 《图书馆杂志》2020,(4):21-26

《争取持久和平,争取人民民主!》是20世纪40年代中后期,欧洲九个社会主义国家的共产党和工人党为了一致行动而建立的情报局机关刊物。该刊物对新中国初期我国经济社会建设及成就进行了大量宣传与报道,对加强我国与世界其他爱好和平、渴求民主的各国人民加强互信、长存友谊贡献很大,也对当前学者研究新中国初期我国经济社会发展的过程、成就和经验等提供了原始史料,学术研究意义也很重大。但是,目前对这份刊物及其发挥过的重大作用了解的人少之又少,时值中国共产党成立100周年之际,对其创刊与发行的历史过程进行回顾、宣传中国社会经济发展的全貌进行展示、推动世界社会主义运动的作用进行肯定,意义都很重大。  相似文献   

Creating a Continuing Education Pathway for Newly Arrived Immigrants and Refugee Communities     

Aster S. Tecle  An Thi Ha 《Journal of Teaching in Social Work》2017,37(2):171-184

With the increase in the number of displaced peoples, the demand for skilled social workers from diverse backgrounds to serve them is critical. This article explores a continuing education program that prepares precollege individuals from newly arriving communities who will work as entry-level workers serving these immigrant and refugee communities. The article focuses on the development of a Case Management Certificate Program as a response to community-identified issues, then presents a discussion exploring the educational pathways and unique contributions of these individuals. The article calls for the profession to explore how continuing education pathways can bridge service gaps, contribute to the knowledge base of social work, and meet current labor market demands.  相似文献   

Assessing and tracking students’ problem solving performances in anchored learning environments     

Brian A. Bottge  Enrique Rueda  Jung Min Kwon  Timothy Grant  Perry LaRoque 《Educational technology research and development : ETR & D》2009,57(4):529-552

The purpose of this randomized experiment was to compare the performance of high-, average-, and low-achieving middle school students who were assessed with parallel versions of a computer-based test (CBT) or a paper-pencil test (PPT). Tests delivered in interactive, immersive environments like the CBT may have the advantage of providing teachers with diagnostic tools that can lead to instruction tailored to the needs of students at different achievement levels. To test the feasibility of CBT, students were randomly assigned to the CBT or PPT test conditions to measure what they had learned from an instructional method called enhanced anchored math instruction. Both assessment methods showed that students benefited from instruction and differentiated students by achievement status. The navigation maps generated from the CBT revealed that the low-achieving students were able to navigate the test, spent about the same amount of time solving the subproblems as the more advanced students, and made use of the learning scaffolds.

OCCUPATIONAL/CAREER INDECISION FOR ECONOMICALLY DISADVANTAGED HIGH SCHOOL STUDENTS OF HIGH INTELLECTUAL ABILITY: A MIXED‐METHODS COGNITIVE PROCESS MODEL          下载免费PDF全文

Jae Yup Jung  Marie Young 《Psychology in the schools》2017,54(7):718-735

A mixed‐methods design was employed to identify the cognitive processes that lead to occupational/career indecision for economically disadvantaged adolescents of high intellectual ability. In the first phase, interview data collected from 26 economically disadvantaged intellectually gifted Australian adolescents were analyzed using grounded theory to develop two alternative models of cognitive processes that lead to occupational/career indecision. In the second phase, these models were quantitatively tested and refined using structural equation modeling of survey data collected from 917 economically disadvantaged intellectually gifted Australian adolescents. The finally accepted model, identified using a competing models strategy, suggested that valuing the thoughts of family on general matters is positively predictive of a desire to live up to one's potential and the experience of amotivation about the occupational decision. In turn, occupational amotivation appears to be positively associated with occupational indecision, but negatively associated with multipotentiality and a desire to fulfill one's potential.  相似文献
