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

This paper takes up understandings of organisations where practices constitute and frame past and present work, as well as
future work practice possibilities. Within this view, work practices, and thus organisations, are both perpetuated and varied
through employees’ enactments of work. Using a practice lens, we are particularly interested in the ways workers simultaneously
maintain and alter practices in their workplace—we characterise this as re-making one’s job. This perspective challenges ways
in which managers often depict jobs and everyday work—as rational, linear and easily describable. We suggest that workers
at various levels of responsibility contribute more to the formation of organisational practices than is often assumed. The
processes of re-making jobs and remaking organisational practices create tensions that we posit as sites for learning. This
paper addresses these issues through a focus on work practices in two Australian organisations that have been undergoing significant
cultural change. 相似文献

Customer Relationship Management (CRM) is a very important growing business practice in today's environment. It is used for managing the interaction between a company and its future and current customers. CRM approach's task is analyzing data about the history of customers with a company. It focuses on a way to retain customers, therefore it helps the growth of sales. This leads to improvement of company's business relationship with customers. Current study's goal is to determine how technology, organizational capability, customer orientation, and customer knowledge management influence CRM success. We try to see that how the performance of an organization is affected by the achievement of CRM. For testing the hypotheses, Partial Least Squares Structural Equation Modeling (PLS-SEM) was adopted. Results have indicated that the success of CRM is highly influenced through “information technology use”, also “customer orientation”, “organizational capability”, and “customer knowledge management” are related to CRM success. Finally, along with the future research avenues and limitations, study implications and findings are discussed. 相似文献

Stronger protection of patent rights is thought to spur innovation through securing returns to R&D investments. Those investments must be financed, however, suggesting that the responsiveness of R&D to patent reforms varies with financial development levels. We examine the joint impact of domestic and international financial-market development and patent protection on R&D intensities in 22 manufacturing industries in 20 OECD countries for the period 1990-2009. We show that stronger patent rights increase R&D intensities in patent-intensive industries, accounting for the need for external financing and the amount of tangible assets. The primary impact varies across types of financial development: patent protection raises R&D in high-patent industries where countries have more limited equity and credit markets. In contrast, in countries with more developed bond markets industry R&D is more sensitive to patent rights. Interestingly, patent rights in countries that are more exposed to foreign direct investment increase R&D intensities at all levels of financial development. 相似文献
