This article examines People-Based Marketing (PBM) to theorize the cultural economies of attribution metrics. Through an analysis of marketing discourses, acquisition patterns, and marketing collaborations, it examines how platform capitalism is increasingly directed towards developing cross-device identity standards that consolidate performance metrics across digital markets. PBM extends the processes of platform capitalization across media properties, and the ways that claims of value and relevance are imbricated with the metricization of behavioral change in digital markets. The imperative of PBM to standardize techniques of identification and to make media increasingly measurable across markets has been a catalyst for new forms of data resolutions through strategic acquisitions and identity resolution consortiums. Moreover, emerging regulatory changes such as GDPR may in effect further reinforce trends towards the consolidation of data management and analytics platforms necessary to resolve identity across markets. 相似文献

Phenomenologies of sport predominantly focus on an analysis of the experience of participating in sport, either as a part of a team or individually. In this essay, the author argues that a vital avenue for the phenomenology of sport has not been adequately explored, that is, an analysis of the experience of the spectator. Taking up Heidegger’s phenomenological method as outlined in Being and Time, the author argues that Heidegger’s notions of the they-self, idle talk, and falling prey offer critical insights into why sports-talk among fans comes to focus on truth and blame. The object of the phenomenology of sport is thus suggested to be not limited solely to the field of play but is also, as the title suggests, in the bleachers as well. 相似文献

Sporting performance is often investigated through graphical observation of key technical variables that are representative of whole movements. The presence of differences between athletes in such variables has led to terms such as movement signatures being used. These signatures can be multivariate (multiple time-series observed concurrently), and also be composed of variables measured relative to different scales. Analytical techniques from areas of statistics such as Functional Data Analysis (FDA) present a practical alternative for analysing multivariate signatures. When applied to concurrent bivariate time-series multivariate functional principal components analysis (referred to as bivariate fPCA or bfPCA in this paper) has demonstrated preliminary application in biomechanical contexts. Despite this, given the infancy of bfPCA in sports biomechanics there are still necessary considerations for its use with non-conventional or complex bivariate structures. This paper focuses on the application of bfPCA to the force-angle graph in on-water rowing, which is a bivariate structure composed of variables with different units. A normalisation approach is proposed to investigate and standardise differences in variability between the two variables. The results of bfPCA applied to the non-normalised data and normalised data are then compared. Considerations and recommendations for the application of bfPCA in this context are also provided. 相似文献

Relations among child care quality, teacher behavior, children's play activities, emotional security, and cognitive activity in child care 总被引:1,自引:0,他引:1
Eight hundred forty children (435 girls) enrolled in full-time, center-based child care participated in the study. Children ranged in age from 10 to 70 months. Sixty-six percent of the children were European American, the remainder African American. Children's play activities and cognitive activities as well as their relationships with caregivers were observed within the child care setting. The study tested the prediction that variation in children's cognitive activities could be directly and indirectly explained by child care quality, positive social interaction with teachers, and children's play activities and attachment security with their child care teachers. The prediction was examined and at least partially supported in eight subsamples of infant-toddler and preschool age European American and African American children in subsidized and nonsubsidized child care. Specifically, in seven of the eight subsamples, 15 to 30% of the variability in children's cognitive activities could be predicted from positive social interaction with teachers, attachment security, and participation in creative play activities. 相似文献

ABSTRACTZoos and aquariums are popular visitor destinations, with around 30 million visits made to them annually throughout the UK and Ireland. The role and mission of modern zoos have evolved, with the conservation of world’s remaining biodiversity now being their major purpose. They seek to aid biodiversity through a combination of public education, in situ and ex situ conservation programmes, and applied scientific research. Directly relevant to this paper, they are also institutions that actively recruit, attract and utilise volunteers. However, the impacts of volunteering in zoos and aquariums, on the volunteers themselves, are under-researched. Here we show that, in a survey of more than 500 volunteers at 19 different zoological collections in the UK, zoo volunteers report positive impacts, specifically in relation to increases in their human and social capital. We also found that these benefits were more pronounced in younger volunteers, and with those volunteers who received more initial training. We conclude that while volunteering in UK zoos correlates with significant personal benefits to individuals, zoos could aim higher and should seek to do more to maximise the positive effects of connecting volunteers with the wildlife and nature found in zoo settings, as well as tailoring their volunteer training programmes for different age groups. 相似文献

Adopting an integrated achievement goal (Nicholls, J. G. (1989). The competitive ethos and democratic education. Cambridge, MA: Harvard University Press.) and self-determination theory (Deci, E. L., & Ryan, R. M. (2000). The “what” and “why” of goal pursuits: Human needs and the self-determination of behavior. Psychological Inquiry, 11, 227–268. doi:10.1207/S15327965PLI1104_01) perspective as proffered by Duda, J. L. (2013). (The conceptual and empirical foundations of empowering coachingTM: Setting the stage for the PAPA project. International Journal of Sport and Exercise Psychology, 11, 311–318. doi:10.1080/1612197X.2013.839414), the aim of the current study was to observe empowering and disempowering features of the multidimensional motivational coaching environment in training and competition in youth sport. Seventeen grass-roots soccer coaches were observed and rated in training and competitive settings using the multidimensional motivational climate observation system (MMCOS; Smith, N., Tessier, D., Tzioumakis, Y., Quested, E., Appleton, P., Sarrazin, P., … Duda, J. L. (2015). Development and validation of the multidimensional motivational climate observation system (MMCOS). Journal of Sport and Exercise Psychology, 37, 4–22. doi:10.1123/jsep.2014-0059). In line with our hypotheses, coaches created different motivational environments in the two contexts. More specifically, coaches were observed to create a less empowering and more disempowering environment in competition compared to in training. The observed differences were underpinned by distinctive motivational strategies used by coaches in the two contexts. Findings have implications for the assessment of the coach-created motivational environment and the promotion of quality motivation for young athletes taking part in grass-roots-level sport. 相似文献

Purpose: An objective database for physical education (PE) is important for policy and practice decisions, and the System for Observing Fitness Instruction Time (SOFIT) has been identified as an appropriate surveillance tool for PE across the nation. The purpose of this review was to assess peer-reviewed studies using SOFIT to study K–12 PE in U.S. schools. Method: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses informed the review, and 10 databases were searched for English-language articles published through 2016. A total of 704 records identifying SOFIT were located, and 137 full texts were read. Two authors reviewed full-text articles, and a data extraction tool was developed to select studies and main topics for synthesis. Results: Twenty-nine studies that included direct observations of 12,256 PE lessons met inclusion criteria; 17 were conducted in elementary schools, 9 in secondary schools, and 3 in combined-level schools. Inconsistent reporting among studies was evident, including not all identifying the number of classes and teachers involved. All studies reported student physical activity, but fewer reported observer reliabilities (88%), lesson context (76%), teacher behavior (38%), and PE dosage (34%). The most frequently analyzed independent variables were teacher preparation (48%), lesson location (38%), and student gender (31%). Conclusions: SOFIT can be used reliably in diverse settings. Inconsistent reporting about study procedures and variables analyzed, however, limited comparisons among studies. Adherence to an established protocol and more consistent reporting would more fully enable the development of a viable database for PE in U.S. schools. 相似文献
