Interaction Devices and Web Design for Novice Older Users     

Pei-Luen Patrick Rau  Jia-Wen Hsu 《Educational gerontology》2013,39(1):19-40

ABSTRACT

This study investigated the effects of interaction devices on the Internet performance of novice older users, and ways to provide appropriate voice assistance to enhance browsing and searching performance of such users. Three experiments were designed and conducted to test three hypotheses. The results indicated that touch screen and handwriting recognition are better than mouse and keyboard in browsing time in the third trial. Touch screen was also found to be better in terms of performance time for keyword search tasks than mouse and voice input in the second trial, and is better in terms of user error for keyword search tasks than mouse and voice input in the first trial. Learning effects were found for using touch screen and handwriting recognition, and mouse and keyboard for browsing and searching tasks. Furthermore, voice-menu assistance was associated with higher satisfaction for browsing tasks.  相似文献   

Evaluation of a Community-Based Aging Intervention Program     

Hui-Chuan Hsu  Chun-Hou Wang  Yi-Chun Chen  Ming-Chen Chang  Jean Wang 《Educational gerontology》2013,39(7):547-572

This study evaluated the outcome and process of a community-based aging intervention program for the elderly in Taiwan. The program included education on nutrition and dietary behavior and on physical activities. Outcome and process evaluations were conducted. The program may have had some effects on decreasing some dietary behavioral problems and increasing regular exercise, but the effect on health outcome was not proved. The strength of this program was its proper design, dosage, and implementation; the weaknesses included a low participation rate, low commitment and continuity, and selection bias for the nonparticipants who might be frailer than the actual participants.  相似文献   

Physical Self-Concept,Possible Selves,and Well-Being Among Older Adults in Taiwan     

Yawen Hsu  Frank J. H. Lu  Linda L. Lin 《Educational gerontology》2013,39(9):666-675

Possible selves is an important self-related construct for older adults' health behaviors and well-being. This study examines the relationships among older adults' current physical self-concept, possible selves, and physical activity participation, and it examines the mediating effect of possible selves on the relationships between physical self-concept and well-being. One hundred and sixty-three community-dwelling older adults (M _age = 70.91, SD = 6.39) in Taiwan completed the survey packet assessing physical self concept, possible selves, health-related qualities of life, and life satisfaction. Bivariate correlation analyses showed that older adults' possible selves were positively related to physical self-concept and moderate physical activity participation. In addition, the link between older adults' physical self-concept and psychological well-being was mediated partially by possible selves. The results show the significance of using the construct of possible selves to examine and promote older adults' physical activity/exercise behaviors and psychological well-being.  相似文献   

Gain-scheduled control of PVTOL aircraft dynamics with parameter-dependent disturbance     

Sun-Li Wu  Chih-Hua Hsu 《Journal of The Franklin Institute》2008,345(8):906-925

This paper presents a gain-scheduled control approach for the vertical takeoff and landing aircraft. The non-linear aircraft dynamics are formulated as a linear parameter varying (LPV) system with external parameter-dependent disturbance, which arisen from the equilibrating between gravity force and nozzles thrust. The disturbance is dependent on the system varying parameter, roll angle, and a constant parameter denoting the normalized gravity force. The controllers are designed in terms of mixed optimization of H^∞ performance for disturbance attenuation and relative stability for tracking position command in pitch-yaw plane. The characteristics of the parameter-dependent disturbance are described by an equality condition with a defined annihilation matrix. By exploring the parameter-dependence condition on disturbance into the controller design algorithms based on linear matrix inequalities (LMIs), it is showed that a better performance can be achieved than simply considering it as an external disturbance. The design results are demonstrated by time response simulations.  相似文献   

An Assessment of Environmental Literacy and Analysis of Predictors of Responsible Environmental Behaviour Held by Secondary Teachers in the Hualien Area of Taiwan     

Shih‐Jang Hsu  Robert E. Roth 《Environmental Education Research》1998,4(3):229-249

This study assessed teachers' environmental literacy and analysed predictors of teachers' responsible environmental behaviour (REB). A nine page instrument was administered by mailed questionnaire to 300 randomly selected secondary teachers in the Hualien area of Taiwan with a 52.3% effective response rate. As a result of stepwise multiple regression analyses, the most parsimonious set of predictors of REB for all teachers included: perceived knowledge of environmental action strategies (KNOW), intention to act, area of residence and perceived skill in using environmental action strategies (SKILL, total r² = 0.3867). For urban teachers, the most parsimonious set of predictors included: intention to act, SKILL, major sources of environmental information and membership in environmental organisations (total r² = 0.4711). For rural teachers, the most parsimonious set of predictors included: KNOW, intention to act and perceived knowledge of environmental problems and issues (total r² = 0.3200). Implications for programme development and instructional practice are presented. Recommendations for further research are also provided.  相似文献

Collegiate baseball players with more optimal functional movement patterns demonstrate better athletic performance in speed and agility     

Yu-Pin Liang  Yi-Liang Kuo  Hsiang-Chin Hsu  Yen-Ysung Hsia  Ya-Wen Hsu 《Journal of sports sciences》2019,37(5):544-552

Sports injuries are common among baseball players and may result in abnormal movement patterns, increased risks of future injury, and unsatisfactory performance. The Functional Movement Screen (FMS?) has been developed to detect abnormal functional movement patterns and can be used for predicting risks of sports injury. However, whether FMS? scores are associated with athletic performance remains unclear. The goal of this study was to determine the association between functional movements and athletic performance in elite baseball players. Core stability, muscular strength and flexibility of the lower extremities, and FMS?, as well as athletic performance in sprinting, agility, and balance tests were assessed in 52 male collegiate Division I baseball players placed into two groups based on FMS? scores. The high-scoring group demonstrated better athletic performance than the low-scoring group, with a shorter duration of the agility test. No group differences were found in core stability, muscular strength, or muscle flexibility, except for rectus femoris flexibility. Thus, the FMS? score is associated with sprinting and agility performance in elite baseball players. These findings indicate that the FMS? may have a role in predicting athletic performance and thereby help determine the goals of training regimens or return-to-play strategies.  相似文献   

Using characteristics of serious leisure to classify rock climbers: a latent profile analysis     

KoFan Lee  John Bentley  Hsien-Yuan Mark Hsu 《Journal of Sport Tourism》2017,21(4):245-262

The growth of the climbing industry enables more people to use this sport to promote a healthy lifestyle. Given this trend, it is important to understand the heterogeneity of rock climbers and differences in their attributes, motivations and behaviors. In this study, the characteristics of serious leisure (SL) were used to classify rock climbers. Four hundred and eighty-six rock climbers recruited in this study were classified into three groups: low commitment (LC; N?=?82), high commitment (HC; N?=?355) and dedicated groups (N?=?49). A high mean on the financial return item distinguished the dedicated group (M?=?7.52) from the other two. Subsequently, the results of multinomial logistic regression, with the dedicated group as the baseline category, showed that with increases in experiences (i.e. days of climbing in the past year and years of climbing) and internalized motivations (i.e. intrinsic, identified and introjected motivations), a climber is less relatively likely of being in the LC group. Further, comparing the HC group with the dedicated group, with increases in experiences and introjected motivation, a climber is less likely of being in the HC group. The results of the classification complemented the results of previous qualitative SL studies regarding diverse participation in leisure commitment. The results with respect to motivation supported that internalization is associated with increases in commitment. Service providers should keep current regarding dynamic climbing culture and help clients fulfill diverse needs of commitment to rock climbing. The findings of this study enhance existing knowledge of recreationists’ development in the pursuit of adventure recreation.  相似文献
