Cost effective, quantifiable assessment of lower extremity movement represents potential improvement over standard tools for evaluation of injury risk. Ten healthy participants completed three trials of a drop jump, overhead squat, and single leg squat task. Peak hip and knee kinematics were assessed using an 8 camera BTS Smart 7000DX motion analysis system and the Microsoft Kinect® camera system. The agreement and consistency between both uncorrected and correct Kinect kinematic variables and the BTS camera system were assessed using interclass correlations coefficients. Peak sagittal plane kinematics measured using the Microsoft Kinect® camera system explained a significant amount of variance [Range_hip = 43.5–62.8%; Range_knee = 67.5–89.6%] in peak kinematics measured using the BTS camera system. Across tasks, peak knee flexion angle and peak hip flexion were found to be consistent and in agreement when the Microsoft Kinect® camera system was directly compared to the BTS camera system but these values were improved following application of a corrective factor. The Microsoft Kinect® may not be an appropriate surrogate for traditional motion analysis technology, but it may have potential applications as a real-time feedback tool in pathological or high injury risk populations.  相似文献   

News Habits Among Adolescents: The Influence of Family Communication on Adolescents’ News Media Use—Evidence From a Three-Wave Panel Study     

Adam Shehata 《Mass Communication and Society》2016,19(6):758-781

Keeping up with what’s going on in the world of politics and current affairs through various news media is commonly seen as important for civic engagement and informed citizenship. Today, however, citizens face more opportunities than ever to select media content according to their personal preferences and interests—leading to what previous research has identified as a polarization between news-seekers and news-avoiders. Given heightened concerns regarding growing shares of news-avoiders in particular, this study analyzes the development, stability, and family influences on Swedish adolescents’ news habits over time. The findings, based on panel survey data among adolescents and their parents, show that (a) news habits are fairly stable at the individual level, (b) parents’ own news consumption is the most consistent predictor of adolescents’ development of news habits, and (c) these family effects are distinct from adolescents’ personal motivations for seeking out news.  相似文献

Religious discrimination discourse in the mono-cultural school: the case of Poland     

Adam Anczyk  Joanna Grzymała-Moszczyńska 《British Journal of Religious Education》2018,40(2):182-193

The article forms an analysis of the religious discrimination discourse in Polish public schools, with special attention paid to the culturally specific, Polish understanding of the notion of religious discrimination. The introductory part presents the concept of religious discrimination as present in anti-discriminatory policies. The following part outlines the Polish system of religious education and its relation to the religious discrimination. Studies on religious discrimination in Poland are presented and discussed. Important context is supplied by a presentation of two recent cases of religious discrimination in Polish public schools, and the actions undertaken by the Freedom from Religion Foundation. Authors of the article point out the important influence of cultural context on the perception of religious discrimination. The attention is drawn to the seemingly homogenous environment of the Polish school and of the discriminative discourse used in political and social debates. The analysis shows that the presence of religion as a subject in Polish schools remains a cause of conflict between the religious and atheist citizens, a conflict in which concepts of religious discrimination and religious freedom are used as arguments by both sides.  相似文献   

Convergent designs in fine fashion: An evolutionary model for stylistic innovation     

Rossella Cappetta Author Vitae  Paola Cillo Author Vitae  Anna Ponti Author Vitae 《Research Policy》2006,35(9):1273-1290

In this paper we propose and test an evolutionary model of stylistic innovation, that is the change in the aesthetic and symbolic elements of products and services. Style is an increasingly relevant phenomenon in many industries and our goal is to develop a model of how styles get introduced and adopted. We build on existent literature on technological change to frame the dynamics of how style changes across time. In the model we propose, companies face periods of ferment with relevant stylistic variations and periods of convergence on a single trend—that is the stylistic convergent design versus the technologic dominant design. We identify the drivers of convergence in stylistic innovation. We test the model with a longitudinal empirical study (1984-2002) in the fine fashion industry, explaining the main differences between a stylistic and a technological evolutionary model.  相似文献   

Does gender matter in computer ethics?   总被引：6，自引：0，他引：6  

Alison Adam  Jacqueline Ofori-Amanfo 《Ethics and Information Technology》2000,2(1):37-47

Computer ethics is a relatively young discipline,hence it needs time both for reflection and forexploring alternative ethical standpoints in buildingup its own theoretical framework. Feminist ethics isoffered as one such alternative particularly to informissues of equality and power. We argue that feministethics is not narrowly confined to women's issues but is an approach with wider egalitarianapplications. The rise of feminist ethics in relationto feminist theory in general is described and withinthat the work of Gilligan and others on an ethic of care. We argue for the need to connect theory toempirical evidence. Empirical studies of gender andbusiness and computer ethics are reviewed. We noteconcerns with surveying a student audience, the issueof how far questionnaires and interviews can get tothe heart of ethical beliefs and problems ofperforming statistical analyses of quantitative data.Although we recognize them, our own small surveycannot avoid all these problems. Nevertheless byrefining our scenarios we are able to offer analternative reading of a hacking problem in terms ofan ethic of care thereby pointing a way forward forfuture research in computer ethics inspired byfeminist theory.  相似文献

Impact of Contact With Grandparents on Children's and Adolescents’ Views on the Elderly     

Allison Flamion  Pierre Missotten  Manon Marquet  Stéphane Adam 《Child development》2019,90(4):1155-1169

Stereotypes, prejudice, and discrimination against the elderly (ageism) may manifest themselves in children at an early age. However, the factors influencing this phenomenon are not well known. Using both explicit and open-ended questions, this study analyzed the influence of personal and familial parameters on the views of 1,151 seven- to sixteen-year-old Belgian children and adolescents on the elderly. Four factors were found to affect these views: gender (girls had slightly more positive views than boys), age (ageism was lowest in 10- to 12-year-old, reminiscent of other forms of stereotypes and cognitive developmental theories), grandparents’ health, and most importantly, quality of contact with grandparents (very good and good contacts correlated with more favorable feelings toward the elderly, especially in children with frequent contacts).  相似文献   

What Does a Modern Anatomist Look like? Current Trends in the Training of Anatomy Educators     

Audra F. Schaefer  Adam B. Wilson  J. Bradley Barger  Homaira M. Azim  James J. Brokaw  William S. Brooks 《Anatomical sciences education》2019,12(3):225-235

Anatomical sciences are foundational to the health professions, yet little is known about the qualifications of anatomy educators at the graduate and professional level in the United States. Moreover, there is concern that the number of qualified anatomy educators being trained may be insufficient to meet the growing demand posed by new and expanded programs in medicine and allied health specialties. The authors surveyed anatomists from across the country to (i) characterize the educational credentials of current anatomy educators and (ii) assess the perceived need for education-focused postdoctoral positions or formal mentorships to prepare anatomists for teaching-intensive faculty positions. To probe the survey responses more deeply, one-on-one interviews were conducted with eight individuals selected to represent a diverse sample of respondents in terms of institution, gender, and academic rank. Results indicate that 30–40% of educators at the graduate level and approximately 60% of those at the undergraduate level lack graduate coursework in histology, embryology, and neuroanatomy. Forty-five percent of respondents had completed a postdoctoral fellowship. Eighty-six percent replied “yes/maybe” to the question of whether an anatomy education postdoctoral fellowship would benefit doctoral graduates. The top 3 reasons for this recommendation were to (i) establish independent educational research, (ii) improve a publication record, and (iii) gain additional teaching experience. Notable weaknesses of education-focused postdoctoral training were related to finances, fear of exploitation, and undervaluing of teaching. Moving forward, postdoctoral fellowships and other forms of postgraduate training may represent a key strategy for training anatomists in the current educational climate.
