This paper examines a controversial research programme aimed at the production of transgenic cows in New Zealand. It emphasizes the contested representation of the research, in its promotion, in its governance, and in the opposition sparked amongst environmentallanti-genetic modification groups and within the Māori community. The paper contends that the case of New Zealand's genetically modified cows certainly reveals some unique features of the prevailing economic, geographical and cultural context, but nonetheless has salience for the broader understanding of the promotion, public reception and governance of genetic modification. 相似文献

Movement patterns and physical strain during a novel, simulated cricket batting innings (BATEX) 总被引:1,自引:1,他引:0
A simulated cricket batting innings was developed to replicate the physical demands of scoring a century during One-Day International cricket. The simulated innings requires running-between-the-wickets across six 5-over stages, each of 21 min duration. To validate whether the simulated batting innings is reflective of One-Day International batting, movement patterns were collected using a global positioning system (GPS) and compared with previous research. In addition, indicators of physical strain were recorded (heart rate, jump heights, sweat loss, tympanic temperature). Nine club cricketers (mean ± s: age 20 ± 3 years; body mass 79.5 ± 7.9 kg) performed the simulated innings outdoors. There was a moderate trend for distance covered in the simulated innings to be less than that during One-Day batting (2171 ± 157 vs. 2476 ± 631 m · h?1; effect size = 0.78). This difference was largely explained by a strong trend for less distance covered walking in the simulated innings than in One-Day batting (1359 ± 157 vs. 1604 ± 438 m · h?1; effect size = 1.61). However, there was a marked trend for distance covered both striding and sprinting to be greater in the simulated innings than in One-Day batting (effect size > 1.2). Practically, the simulated batting innings may be used for match-realistic physical training and as a research protocol to assess the demands of prolonged, high-intensity cricket batting. 相似文献

Schools are an important context for both basic and applied scientific research. Unlike the laboratory, however, the physical and social conditions of schools are not under the exclusive control of scientists. In this article, we liken collecting data in schools to putting on a theatrical production. We begin by describing the large cast of characters whose collaborative efforts make school‐based research possible. Next, we address the critics, including the university Institutional Review Board (IRB) and school administrators, whose feedback often improves the final study design. We then turn our attention to set building, stage directions, and rehearsals—key steps in the iterative process of refining study procedures. We end with a discussion of the day of data collection itself and activities that take place after the curtain drops. Throughout, we make recommendations based on our recent experience collecting data at several high schools. 相似文献

Bodystorming is a technique used by designers to better understand how the settings where interactive systems are deployed might affect their intended uses. The articulation of design concepts “in the wild” and using forms of performance and improvisation are intended to help designers become more aware of contextual issues that may not be revealed in traditional brainstorming exercises. Bodystorming can be a useful technique for designers of mobile learning experiences, as it helps make interactions between learners, devices, and locations more explicit. The general method is described in this paper and followed by two case studies of its use in the design of mobile learning experiences. 相似文献

Predictors of developmentally appropriate classroom practices in kindergarten through third grade 总被引:2,自引:0,他引:2

This study was designed to (a) test the psychometric properties of a new observation measure of developmentally appropriate classroom practices in kindergarten through third-grade classrooms, and (b) determine how well classroom and teacher characteristics predict developmentally appropriate classroom practices. Teacher-reported and observational data from 69 classrooms provided support for construct validity, internal consistency, and interrater agreement of the Assessment of Practices in Early Elementary Classrooms (APEEC) measure. Hierarchical multiple regression analyses indicated that classroom characteristics (grade, class size, number of children with disabilities), teacher characteristics (education level, years of experience) and teacher beliefs (developmentally appropriate beliefs and developmentally inappropriate beliefs) accounted for 42% of the variance in observed classroom practices. With all variables in the model, teacher education, grade, and beliefs in developmentally appropriate and inappropriate practice accounted for most of the variance in observed classroom practices. 相似文献

The study extends agenda-setting research by examining issuediversity as a consequence of media exposure. Results from twosurveysone conducted in the United States, the otherin Taiwanillustrate differences in the cultures of thetwo samples. In general, older individuals who find low utilityin advertising information but who read a variety of newspapersand feel a strong civic duty to keep informed believe thereare many important issues facing the United States. Younger,highly educated individuals who have a high interest in politicalnews and who read a variety of newspapers believe there aremany important issues facing Taiwan. 相似文献

Students of Project Adapt (PA), an instructional program for at-risk middle school students in Brooklyn NY, have displayed startling improvement on cognitive outcome measures. Teacher given grades and standardized tests illuminate the progress students have made since entering the program. The current investigation attempts to analyze PA on students' affective responses in a pre/post-test experimental design. Upon entering PA, students completed measures of interest, affect, and their previous teachers' behavior (pre). These ratings were then compared to end of year ratings on the same instruments (post). Results indicate students' perceive PA teachers utilizing different behaviors than their previous teachers. Additionally, student affect and interest increased significantly. Results of this study have implications for both instructional researchers and educational practitioners. 相似文献
