In order to help coaches analyse the techniques of professional in-line speed skaters for making the required fine adjustments and corrections in their push-off work, this study analysed the specific plantar pressure characteristics during a 300-m time-trial test. Fourteen elite in-line speed skaters from the national team were recruited in this study. The total completion time of the 300-m time-trial test, duration of each skating phase, and plantar pressure distribution were measured. The correlation between plantar pressure distribution and skating performance was assessed using Pearson correlation analyses. The results showed that the contact time of the total foot and force–time integral (FTI) in the medial forefoot were significantly correlated with the duration of the start phase, and the FTIs in the medial forefoot of the gliding (left) leg and lateral forefoot of the pushing (right) leg were significantly correlated with the duration of the turning phase. The maximum force in the medial heel, medial forefoot, and median forefoot and the FTI in the medial heel and medial forefoot were significantly correlated with the duration of the linear acceleration phase. The results suggest that a correct plantar loading area and push-off strategy can enhance the skating performance.  相似文献   

Sterilizing society: social order and policing sex work in Taiwan     

Ya-Fei Hsu 《Inter-Asia Cultural Studies》2013,14(2):272-286

This article utilizes Michel Foucault's view of state racism to analyze the criminalization of sex workers in Taiwan. To explore the political significance underlying the term “sex work” for anti-prostitution activists, we must historically situate their discourses and their impact on legal control in the late 1980s women's movements. Their efforts to reform society followed from their commitment to child protection and from their long-standing goal of eliminating women's sexuality through motherhood. An uphill battle, marshaled chiefly by the amendment of the Youth Welfare Act in 1988 and the legislation of CYSTPA in 1995, it became more furious in its assault on sex workers. By 2009, whereas those anti-prostitution activists had promoted anti-human trafficking provisions to protect victims under the age of 18, such provisions had in reality become mechanisms for arresting anyone related with the sex industry. This means that what was put forward as a principle for the integration of society and its visible order was based on sexual inequality. Contrasting the strategies and rhetoric of regulating sex workers in Taiwan, what is really necessary is to bring the cultural dynamics behind policies into a sharper view of state racism.  相似文献

Effects of different exercise intensities with isoenergetic expenditures on C-reactive protein and blood lipid levels     

Tsao TH  Yang CB  Hsu CH 《Research quarterly for exercise and sport》2012,83(2):293-299

We investigated the effects of different exercise intensities on C-reactive protein (CRP), and whether changes in CRP levels correlated with blood lipid levels. Ten men exercised at 25%, 65%, and 85% of their maximum oxygen consumption rates. Participants' blood was analyzed for CRP and blood lipid levels before and after the exercise sessions. Although there was an intensity effect for postexercise high-density lipoprotein levels, there were no significant differences or correlations for postexercise CRP levels or between CRP and lipid levels across the three exercise intensities. In an acute aerobic bout model with isoenergetic expenditures, CRP was not affected by the exercise intensity. Additionally, changes in blood lipid levels might not have been connected to CIRP levels for physically fit participants.  相似文献   

An Analysis of Teacher Discourse that Introduces Real Science Activities to High School Students   总被引：1，自引：0，他引：1  

Pei-Ling Hsu  Wolff-Michael Roth 《Research in Science Education》2009,39(4):553-574

Most academic science educators encourage teachers to provide their students with access to more authentic science activities. What can and do teachers say to increase students’ interests in participating in opportunities to do real science? What are the discursive resources they draw on to introduce authentic science to students? The purpose of this ethnographic and discourse-analytic study is to investigate the ways in which the activities of scientists are discursively presented to high school students in a biology/career preparation course. Data sources were collected by means of observation, field notes, interviews, and videotaped lessons in an eleventh-grade biology/career preparation course. Drawing on discourse analysis, we investigate the discursive resources—or, more specifically and technically, the interpretative repertoires—teachers used to explain and promote opportunities to engage students in real science activities. Our analysis identifies and characterizes six types of interpretative repertoires: specialized, a-stereotypical, relevant, empirical, emotive, and rare-opportunity. To better understand the “big picture” of how these discursive resources are drawn on in the classroom, we also report on the frequencies of the repertoires in the discourse and the ways in which repertoires changed in the course of teacher-student interactions. The findings of this case study offer teachers and researchers with a better understanding of how specific forms of discourse—i.e., the repertoires—can serve as resources to enhance teacher-introduction of authentic science to students and provide students a bridge between school and authentic science.  相似文献   

Value of video-assisted thoracoscopic surgery in the diagnosis and treatment of pulmonary tuberculoma: 53 cases analysis and review of literature   总被引：1，自引：0，他引：1  

Kun-Yen Hsu  Hwa-Chan Lee  Chien-Chih Ou  Shi-ping Luh 《Journal of Zhejiang University. Science. B》2009,10(5):375-379

Tuberculoma of the lung is one of manifestations in tuberculosis and usually presents as a solitary pulmonary nodule (SPN). It is difficult to differentiate tuberculoma from SPN by other benign or malignant diseases. At present, the crucial role of video-assisted thoracoscopic surgery (VATS) in diagnosis and treatment of pulmonary diseases has been well acknowledged. Here, we reported 53 patients undergoing VATS resection for tuberculomas in our series. No postoperative mortality was found and only two patients experienced prolonged air-leakage (>7 d) and two had minor wound infections that were recovered after anti-tuberculosis or antibiotic treatment. Anti-tuberculosis chemotherapy from 6 to 12 months was routinely used postoperatively. We conclude that VATS is a satisfactory tool for the diagnosis and treatment of tuberculoma and can also establish a reliable diagnosis for all patients with SPNs.  相似文献   

Chest wall abscess due to Prevotella bivia     

Gwo-jong Hsu  Cheng-ren Chen  Mei-chu Lai  Shi-ping Luh 《Journal of Zhejiang University. Science. B》2009,10(3):233-236

Prevotella bivia is associated with pelvic inflammatory disease. A 77-year-old man developed a rapidly growing chest wall abscess due to P. bivia within days. He underwent surgical resection of the infected area; his postoperative course was uneventful. This is the first case of chest wall abscess due to P. bivia infection. Its correct diagnosis cannot be underestimated because fulminant infections can occur in aged or immunocompromised patients if treated incorrectly. Prompt, appropriate surgical management, and antibiotic therapy affect treatment outcome.   相似文献   

Linguistic intergroup bias tells ingroup/outgroup orientation of bicultural Asian Americans     

Ling-Hui Hsu 《Int J Intercult Relat》2011,35(6):853-866

Traditional studies of ethnic relations focus on racialization between Whites and Blacks, or ethnic stratification between Whites and people of color. This study aims at broadening conventional studies of interethnic relations to examine racial attitudes among people who have internalized more than one culture – i.e., the biculturals and multiculturals. Social psychological research suggests that bicultural individuals are capable of switching between two cultural meaning frames depending on contextual demands. Bicultural individuals vary in how well they integrate the two cultural identities internalized in them – i.e., their bicultural identity integration levels (BII levels). Their BII levels lead to either culturally congruent or culturally incongruent behaviors among bicultural individuals. The underlying assumption of linguistic intergroup bias indicates that people tend to describe more abstractly observed positive ingroup behaviors and negative outgroup behaviors and describe more concretely observed negative ingroup behaviors and positive outgroup behaviors. In this study, bicultural Asian American participants are hypothesized to use language of either higher or lower abstraction to describe actions of positive and negative valence performed by either ethnic Asians or European Americans depending on the cultural priming they received and their BII levels. The demonstrated pattern of ingroup enhancement and outgroup derogation of the bicultural participants point out the perceived ingroup/outgroup orientation of these biculturals towards their coethnics and people of the mainstream culture. Effects of the cultural priming and impact of BII levels are also discussed.  相似文献   

Effects of performance visualization on employment interviews     

Joe Ayres  Tanichya K. Wongprasert  John Silva  Traci Story  Chia‐Fang Sandy Hsu  Darshan Sawant D. 《Communication quarterly》2013,61(2):160-171

Two studies were undertaken to assess the value of exposing people to performance visualization in order to help them cope with communication apprehension (CA) in employment interviews. The first study, which took place in a laboratory, employed a pre/post‐test experimental design. Seniors who were preparing to enter the job market took part in mock interviews, completed a state communication apprehension (CA) measure, a trait CA measure, and a scale designed to measure negative thinking. Participants were then assigned to performance visualization, placebo, or control conditions. After exposure to the requisite treatment, they participated in another mock interview and completed the same battery of measures. The second study took place in the field. In this study, participants, who were about to undergo a screening interview for a job, completed state and trait CA measures, were exposed to performance visualization, and completed the state and trait CA measures the second time. These studies indicated that exposure to performance visualization related negatively to CA and negative thoughts, as well as positively to being offered a job. It showed no relationship to being asked back for a second interview. The implications of these findings are discussed in the conclusion of this report.  相似文献   

Autonomy and Acceptance of Long-Term Care     

Hui-Chuan Hsu  Yu-Shan Ting  Ting-Wen Jiang  Ming-Chih Chien  Chih-Hsin Chien 《Educational gerontology》2013,39(11):949-962

This study explored the relationship between four types of autonomy (health autonomy, informational autonomy, living autonomy, and financial autonomy) and the acceptance of five types of long-term care (adult day care, respite care, assisted living, unit care, and group home) for the elderly in Taiwan. Data were collected from 167 middle-aged and older people. The acceptance of five types of long-term care ranged from 75.9–84.9%. Financial autonomy and information autonomy were significantly related to acceptance of all five types of long-term care. Living autonomy is related to assisted living and group homes. Policy implications are discussed.  相似文献
