This article describes a half-day preconference that focused on the library as publisher. It examined how the movement from print to online publication has impacted the roles of libraries and their ability to take on new roles as publishers. The session explored the benefits of libraries becoming publishers, and discussed Open Access, what it is and is not and its importance to libraries and scholarly communication. A detailed case study of the publishing operations of the University Library System at the University of Pittsburgh was presented as an example of a successful library publishing program. The session provided an opportunity for participants to discover ways that libraries can be involved in publishing. 相似文献

Company business models are vulnerable to various contingencies in the business environment that may unexpectedly render their business logic ineffective. In particular, technological advancements, such as the Internet of things, big data, sharing economy and crowdsourcing, have enabled new forms of business models that can effectively and abruptly make traditional business models obsolete. By disrupting or even diminishing companies’ revenue streams, environmental contingencies may present a significant threat to business continuity (BC). Evaluating the resilience of business models against these contingencies should therefore be a core area of BC. However, existing BC approaches tend to focus on the continuity of the resources and processes through which a particular business model is accomplished in practice but omit the business model itself. We argue that in order for BC approaches to become holistic and strategic, business models need to become a part of the BC considerations, entailing an expansion of the scope of BC from value preservation to value creation. We propose an approach of Strategic Business Continuity Management, which consists of two parts: (1) sustaining the continuity of the company business model (value preservation) and (2) evaluating and modifying the business model (value creation). We illustrate conceptually the value creation part with an example drawn from the sharing economy. 相似文献

研究模因与语言模因及其在传统外语教学中的体现和运用,分析模因论对英语教学带来的新挑战,使我们进一步认识到:在模因论指导下的传统外语教学模式在现代外语教学中应当给予足够的重视,只有将传统的教学模式和现代的教学模式相结合才是具有中国特色的外语教学。 相似文献

在查阅相关文献资料的基础上,对运动项目推广中的形象代言人进行研究,认为在选择形象代言人时,要充分考虑普通大众的想法和意见,运用科学的方法选择运动员形象代言人,充分展现运动项目的精神理念;选择明星运动员、有潜力的运动员和普通人作为形象代言人;选定形象代言人后,就要对其进行全方位的包装宣传和约束管理;我国各运动项目管理部门需要对运动项目的资源进行充分调查,有意识地选择合适的运动员形象代言人,促进各种运动项目在我国的发展。 相似文献

ABSTRACTThis study identified key somatic and demographic characteristics that benefit all swimmers and, at the same time, identified further characteristics that benefit only specific swimming strokes. Three hundred sixty-three competitive-level swimmers (male [n = 202]; female [n = 161]) participated in the study. We adopted a multiplicative, allometric regression model to identify the key characteristics associated with 100 m swimming speeds (controlling for age). The model was refined using backward elimination. Characteristics that benefited some but not all strokes were identified by introducing stroke-by-predictor variable interactions. The regression analysis revealed 7 “common” characteristics that benefited all swimmers suggesting that all swimmers benefit from having less body fat, broad shoulders and hips, a greater arm span (but shorter lower arms) and greater forearm girths with smaller relaxed arm girths. The 4 stroke-specific characteristics reveal that backstroke swimmers benefit from longer backs, a finding that can be likened to boats with longer hulls also travel faster through the water. Other stroke-by-predictor variable interactions (taken together) identified that butterfly swimmers are characterized by greater muscularity in the lower legs. These results highlight the importance of considering somatic and demographic characteristics of young swimmers for talent identification purposes (i.e., to ensure that swimmers realize their most appropriate strokes). 相似文献
