The purpose of this study was to evaluate the traction characteristics of four different stud configurations on Fédération Internationale de Football Association (FIFA) 2-Star, third-generation artificial soccer turf. The investigated stud configurations were hard ground design, firm ground design, soft ground design, and an experimental prototype. The concept of this study combines performance, perception, biomechanical, and mechanical testing procedures. Twenty-five soccer players took part in the different testing procedures. Variables of this study were: running times, subjective rankings/ratings, ground reaction forces, and mechanical traction properties. Statistical discrimination between the four stud configurations was shown for performance, perception, and biomechanical testing (p < 0.05). Unsuited stud configurations for playing on artificial turf are characterized by less plain distributed and pronounced studs. 相似文献

The purpose of this article is to discuss and describe how a clinical research method can be used to generate knowledge about teaching and learning. This will be addressed from a teacher researcher’s perspective, taking a conducted Learning Study as the departure. Learning Study is an interventionist, iterative and collaborative research approach, focusing on the teaching of an object of learning. The actual study was conducted by a teacher researcher leading a teacher research team in a study about story-writing in primary school. The research process and the results are discussed using four areas that are described as dichotomies by Labaree (Labaree, D.F. 2003. “The Peculiar Problems of Preparing Educational Researchers.” Educational Researcher 32 (4): 13–22). Labaree states that teacher researchers need to go from being normative, experimental, personal and particular to being analytical, theoretical, intellectual and universal. By using examples from the Learning Study, I argue that these areas do not have to be seen as dichotomies; instead they can be combined and intertwined. Thus, in a Learning Study, elements from both the teaching practice and the academic practice matter, thus enhancing the possibility that results are useful for practitioners. 相似文献

The relationship between the judgments of professional reviewers and the economic success of cultural products, such as motion pictures, has been the topic of controversial debates involving both scholars and industry experts. This study builds on previous research that distinguishes an ??influencer effect?? of reviews from a ??predictor effect.?? By empirically separating consumers?? and reviewers?? perceptions of movie quality through an auxiliary regression approach (and thus effectively controls for consumers?? quality perceptions), this study advances the discussion by investigating whether and how isolated reviewer quality perceptions are associated with box office results. The authors empirically test a non-linear effect of reviewers?? quality perceptions on box office returns, including a comprehensive investigation of the moderating forces of this relationship, using regression and simple slope analyses. Data from all 1,370 narrative films released in the United States between 1998 and 2006 reveal that though the short-term box office generally is not influenced by isolated reviewer quality perceptions, a non-linear relationship exists between reviews and long-term box office returns, such that films rated highly by reviewers are more strongly influenced than those that are not. In terms of moderators, the authors find evidence for several arthouse and mainstream characteristics to moderate the relationship between isolated reviewer quality perceptions and box office results. 相似文献

The results of previous cross-section studies suggest that childhood hearing impairment may lead to parental psychosocial stress. The present study investigated whether modifications in parental psychic state can be ascertained in connection with the child's treatment events and the child's hearing and speech status, in a prospective study design. Data were available on 116 fathers and mothers regarding the pre-cochlear implant examination or hearing aid fitting of their child. In the course of the child's treatment, parental quality of life improved from a low to a normal level. Among children who were at the stage of pre-examination for a cochlear implant, better hearing and speech capacity was linked to more severe impairment of the parental state. It is emphasized that the parents whose children showed comparatively good language development at the time of pre-examination for a cochlear implant were especially subjected to stress. 相似文献

New technologies allow the display of text, static visuals, and animations. Although animations are inherently attractive,
they are not always beneficial for learning. Problems may arise especially when animations modify the learner's cognitive
load in an unintended way. In two learning experiments with 40 and 26 university students, the effects of animated pictures
on knowledge acquisition were investigated. Some pictures displayed visual simulations of changes over time, whereas other
pictures could be manipulated by learners to represent different states in time. Results showed that manipulation pictures
had an enabling function for individuals with high learning prerequisites, whereas simulation pictures had a facilitating
function for individuals with low learning prerequisites. However, the facilitating function was not beneficial for learning,
because learners were prevented from performing relevant cognitive processes on their own. A careful analysis of the interrelation
between different kinds of cognitive load and the process of learning is therefore required. 相似文献

The present multimethod longitudinal study aimed at investigating development and stability of implicit memory during infancy and early childhood. A total of 134 children were followed longitudinally from 3 months to 3 years of life assessing different age‐appropriate measures of implicit memory. Results from structural equation modeling give further evidence that implicit memory is stable from 9 months of life on, with earlier performance predicting later performance. Second, it was found that implicit memory is present from early on, and no age‐related improvements are found from 3 months on. Results are discussed with respect to the basic brain structures implicit memory builds on, as well as methodological issues. 相似文献

After nearly two decades of military dictatorship, democratic civic education has been integrated into the Ethiopian school curriculum. This paper examines the policy–practice concordance in implementing the civic education curriculum based on empirical evidence generated on the philosophical underpinnings, curricular contents, pedagogical approaches, and the role of instructional technology. Data were gathered through a questionnaire survey on 179 randomly selected high school students, key informant teachers, and content analysis of students’ textbooks, teachers’ guides, and official policy documents. The findings reveal that the existing civic and ethical education curriculum is eclectic in its character blending the minimal interpretation of democratic civic education with the inclusive conception of ethno-cultural diversity relevant to multicultural societies. Nevertheless, the manner in which the TV-instruction is used in classrooms is found to hinder interactive learning that is instrumental to nurture democratic and active citizens. 相似文献
