Several researchers have proposed that power, rather than gender, accounts for women using more powerless language than men. The present study examined the specific interaction context of bargaining and compared power with gender as potential predictors of the use of threats, one particular form of powerful language. Grounded in an interactional/social exchange view of power as dependence in social transactions, this study represented a marked departure from past studies of gender‐based language. The results largely supported power rather than gender as the best predictor of the use of powerful language in an interactional context involving bargaining.  相似文献

Isometric tests have been used to assess rate of force development (RFD), however variation in testing methodologies are known to affect performance outcomes. The aim of this study was to assess the RFD in the isometric squat (ISqT) using two test protocols and two testing angles. Eleven participants (age: 26.8 ± 4.5 years, strength training experience: 7.1 ± 3.03 years) completed test and retest sessions one week apart, whereby two test protocols with respect to duration and instructions were compared. Isometric peak force (ISqTpeak) and isometric explosive force (ISqTexp) tests were assessed at two joint angles (knee flexion angle 100° and 125°). Force-time traces were sampled and subsequently analysed for RFD measures. Average and instantaneous RFD variables did not meet reliability minimum criteria in ISqTpeak at 100° or 125°. The ISqTexp test at 100° met reliability criteria in the RFD 0–200 and 0–250ms variables. The ISqTexp test at 125° met reliability criteria in the RFD 0–150, 0–200 and 0–250ms variables. Force-time characteristics were optimized at the higher knee joint angle. Average and instantaneous RFD measures obtained using a traditional peak force test do not meet basic reliability criteria. Researchers assessing multi-joint RFD should employ the explosive RFD test protocol as opposed to the traditional isometric peak force protocol.  相似文献

This paper explores the role of digital media and creativity in the processes of learning that occur in groups of urban skateboarders. In particular, it examines how the production and consumption of amateur videos contribute to both skaters’ mastery of the techniques of the sport and their integration into the culture of the sport. The data come from an ethnographic study of skateboarders in Hong Kong, which included in-depth interviews, participant observation and the collection of texts and artifacts like magazines, blog entries and amateur skating videos. Skateboarders use video in a number of ways that significantly impact their learning and integration into their communities. They use it to analyze tricks and techniques, to document the stages of their learning and socialization into the group, to set community standards, to build a sense of belonging with their ‘crews’ and to imagine ‘idealized futures’ for themselves and their communities. Understanding the value and function of such ‘semiotic mediation’ in learning and socialization into sport cultures, I suggest, can contribute to helping physical educators design tasks that integrate training in physical skills with opportunities for students to make meaning around their experiences of sport and physical education.  相似文献

OBJECTIVE: Although many studies have identified associations between childhood maltreatment and later substance use and disordered eating, few have examined causal or explanatory pathways, and whether victim characteristics predict the development of one versus the other of these outcomes remains uninvestigated. Furthermore, relatively little childhood maltreatment research has examined Latino samples. To address these gaps, this study examined among Latina adolescents the effects of sexual abuse, physical/emotional abuse, neglect, disconnection from family, and parental alcohol problems on poly-substance use and disordered eating, and whether five individual characteristics explain or differentiate these outcomes. METHOD: Data from a community sample of 361 Latina adolescents were analyzed using structural equation modeling. RESULTS: Physical/emotional abuse predicted poly-substance use and weight concerns, and these associations were mediated by impaired current attachment. Disconnection from family predicted bulimic behaviors, and this association was mediated by dysphoria. One indirect path also emerged: Disconnection from family predicted low social conformity, and low social conformity predicted poly-substance use. Childhood sexual abuse did not uniquely predict any adverse outcome or individual characteristic examined. CONCLUSIONS: Dysphoria and impaired current attachment appear to play important roles in the development of substance use and disordered eating in Latina adolescents when physical/emotional abuse or disconnection from family predicts these outcomes. Dysphoria and low social conformity may differentiate the development of bulimic behaviors and poly-substance use, respectively, when family disconnection predicts these outcomes.  相似文献

Improving the quality of higher education for all students requires researchers to focus on factors that potentially influence learning. Of particular interest are student entry characteristics and effective teaching behaviors. Accordingly, structural equation modeling was used to examine the relationships between student differences, prior experience with the subject material, past performances, teaching behaviors, and perceived learning and achievement. A theoretical model containing 8 variables was formulated and tested on students who were either experienced or inexperienced with the course material. The data were gathered at a large midwestern university fitting the Carnegie classification as a research institution. Overall, student achievement is affected by test anxiety and high school GPA. Prior experience with the course content revealed that content-unfamiliar students' perception of learning is more positively influenced by instructor organization than by instructor expressiveness, whereas for content-familiar students, expressiveness is much more influential than organization. Additionally, content-unfamiliar students are more sensitive to both teaching behaviors than content-familiar students. These findings have important implications for administrators, instructors, and researchers.  相似文献

AECT and NCATE     
Rodney Earle 《TechTrends》2000,44(3):53-57
AECT is a committed partner with NCATE in its belief that every child in America has the right to be taught by a well-prepared, qualified teacher. AECT, always a strong proponent of accreditation and licensure, has been a strong ally and supporter of NCATE for over thirty years. In recent action, AECT’s Board of Directors reaffirmed its commitment to, partnership with, and acknowledgement of NCATE as the national organization that authorizes the professional accreditation programs that produce America’s teachers and other education specialists. We call upon all such programs to seek national accreditation  相似文献

The purpose of this article is to examine how and to what extent schools’ responses to accountability policies in the United States influence the ability of new teachers of color to draw on their own and their students’ cultural resources to engage in culturally responsive teaching. A 5-year study of 17 new teachers of color reveals that these teachers identified three principal tensions which correspond to the three dimensions of culturally responsive teaching: (a) cultural and linguistic relevance versus standardization, (b) community of learners versus teacher transmission, and (c) social justice versus enhanced test scores. The teachers also described two mechanisms by which accountability-based programs and policies were enforced: fear of monitoring and internalizing the link between testing and educational opportunity. We applied the metaphor of “double bind” to explain the tensions and enforcement mechanisms encountered by these teachers. The “double bind” forced the new teachers of color to enact contradictory systemic demands promoted by government policy and the teaching profession and exacted an individual toll. We conclude with implications for policy, practice, and research.  相似文献

Student engagement has rapidly developed a central place in the quality agenda of Australian universities since the introduction of the Australasian Survey of Student Engagement (AUSSE). The AUSSE is based on one developed in the USA. The main arguments given for adopting this survey in Australia are that it provides a valid instrument for measuring engagement and that it enables international comparisons. However, the survey instrument and scales have been adopted with little scrutiny of these arguments. This paper examines these arguments by considering different perspectives of engagement, examining the importance of contextual differences and evaluating the AUSSE engagement scales in the light of both. The paper concludes that the AUSSE results should be used by universities and policy‐makers with caution.  相似文献
