Using Consumer Data to Illustrate How the Library Channel Drives Digital Sales     

David Burleigh 《Publishing Research Quarterly》2017,33(4):380-391

The library channel is often underappreciated as a key part of a publisher’s business strategy. In an age where publishers are constantly seeking new revenue and marketing opportunities, presence in the library—digitally—can yield significant growth. This paper examines the library channel, its business model based on library lending, the performance of eBooks and audiobooks across all subjects, and consumer reading behavior. Digital Book Clubs, a relatively new phenomenon, are also defined and illustrated with examples demonstrating the library’s valuable role in increasing discoverability and ultimately sales.  相似文献

Social media use in the career development of graduate students: the mediating role of internship effectiveness and the moderating role of Zhongyong     

Changqing He  Jibao Gu  Wei Wu  Xuesong Zhai  Jun Song 《Higher Education》2017,74(6):1033-1051

This paper proves that social media use can contribute in important ways to employability outcomes. Specifically, results from a survey of 196 recent graduate students in China indicate that social media use is positively related to employability skills. Internship effectiveness serve as a mediating mechanism through which social media use affects employability skills. Zhongyong has a moderating effect on the social media use-internship effectiveness relationship. In addition to the direct moderating effect, Zhongyong is found to moderate the indirect relationship between social media use and employability skills. We discuss implications of these results for research and practice.  相似文献

International football tournaments,emotional entrainment and the reproduction of symbolic boundaries. A case study in Germany     

Sven Ismer  Manuela Beyer  Carolina Solms-Baruth  Christian von Scheve 《Soccer & Society》2017,18(4):554-574

Understanding the social consequences of major soccer events is important for social science researchers and policy-makers alike. On the one hand, socially integrative effects are ascribed to these events. On the other hand, they are suspected of increasing the devaluation of minorities and disadvantaged groups. Sociological theories in a Durkheimian tradition suggest that the emotional entrainment that goes along with football-related rituals might play a role. We thus investigated the effects of the World Cup 2010 on the derogation of minorities and disadvantaged groups in Germany and hypothesized that the emotional entrainment is a predictor of changes in derogation. Results of our naturalistic study show significant increases in derogative attitudes after the World Cup. Contrary to our expectations, emotional entrainment is not associated with this increase. We discuss possible alternative explanations, in particular the influence of public discourse.  相似文献   

Development of a markerless optical motion capture system for daily use of training in swimming     

Ferryanto Ferryanto  Motomu Nakashima 《Sports Engineering》2017,20(1):63-72

The main objective of this research was to develop a markerless optical motion capture system that can be used for daily use in swimming training. The butterfly stroke was targeted since it is considered bilaterally symmetric in motion. The system consisted of a segmentation process to obtain the participant’s silhouettes and a matching process to estimate the pose of the participant. A variable thresholding method was used to extract the silhouettes to solve non-uniform illumination in the recorded swimming video. Prior to the matching process, the human body was modeled as a series of nine segments to help the matching process. The model was then mapped so that it aligned with the silhouettes, which were investigated by similarity of intensity value. To minimize the degree of freedom in image matching, the available joint motion in the swimming human simulation model was used as a priori information for kinematics data of the swimming motion. As a result, the rotation angle’s correlation coefficients between the references and result of the matching process were around 0.95 for trunk, thigh, shank, upper arm, forearm, hand and 0.78 for head, hip and foot. The rotation angle and the velocity of the center of mass were put into the swimming human simulation model for a dynamics analysis. The simulation results show that the velocity obtained in the experiment corresponded to the fluid force exerted on the lower and upper limbs. Consequently, the proposed system of obtaining the joint motion of the butterfly stroke is suitable for daily training and coaching.  相似文献
