监测对于国家公园的科学保护管理与规划具有重要意义。中国正处于国家公园体制建设初期,有必要深入研究如何建立国家公园监测体系。以近20年来发展迅速的美国、加拿大和英国的国家公园监测体系为研究对象,基于文献调查和比较分析,从监测内容框架与指标、数据管理与转化、组织和保障3个方面梳理在各自资源与管理背景下国家公园监测体系的基本特点,并提取出面向规划管理的国家公园监测体系建设的16个基本要点,为我国提供借鉴和启示。 相似文献

The intense development of the tourism industry requires a skilled and qualified workforce. It is important to attract the right candidates to the tourism education, and subsequently provide relevant education to prepare students for the industry after graduation. While work placements may be useful and important to some extent, they are not the ideal solution. Hence, alternative approaches such as simulations and flipped classrooms may be applied. To provide realistic expectations, a closer collaboration between industry operators and education providers is needed. Education providers should assume a more proactive role by inviting tourism operators and integrated them in the tourism education programmes as guest lecturers. 相似文献

In this paper, we focus on the question to what extent machine learning (ML) tools can be used to support systematic literature reviews. We apply a ML approach for topic detection to analyze emerging topics in the literature—our context is accounting and finance research in the Asia–Pacific region. To evaluate the robustness of the approach, we compare findings from the automated ML approach with the results from a manual analysis of the literature. The automated approach uses a keyword algorithm detection mechanism whereby the manual analysis uses common techniques for qualitative data analysis, that is, triangulation between researchers (expert judgement). From our paper, we conclude that both methods have strengths and weaknesses. The automated analysis works well for large corpora of text and provides a very standardized and non-biased way of analyzing the literature. However, the human researcher is potentially better equipped to evaluate current issues and future trends in the literature. Overall, the best results might be achieved when a variety of tools are used together. 相似文献

实现区域经济协调发展是当前我国在块集聚与点极化双重压力下面临的现实难题,长江经济带尤其是欠发达省份承接发达地区产业转移是解决该难题的必然路径选择。产业转移活动因区域主客体特征变量不同,呈现出典型的多发式转移和门槛转移特征,使得区域政策制定缺乏科学指导,陷入盲目拼政策红利的状态。结合效率模型及考虑熵权的经济社会发展协同度分析,测算了2004-2016长江经济带各省(市)年综合产业转移效率,并考察了门槛效应值及变化趋势。结果表明:在考察期内,长江经济带各省(市)产业转移效率提升较为明显,但不少省(市)存在不协调的阶段性平衡关系,且这种关系还未显露经济总量驱动下的协同发展能力。 相似文献

虽然远程交流技术快速发展,但现有研究表明专利发明在很大程度上仍依赖于信息的地理邻近。以中国1992-2009年的1 331个新能源发明专利为研究对象,运用Jung Wonn,Jaffe等的实验设计方法,研究了专利引证的地理邻近是否会随时间递进而增大。结果表明,个人、大学、公司及其它种类发明专利引证的地理邻近会随着时间变化而增大,而政府受到的影响较小。另外,由于区域城市分属不同省份,因此并不能证明区域专利引证的地理邻近也会随着时间变化而增大。 相似文献

This paper examines the relationship between purpose and purposeful organizing and how such arrangements influence the entrepreneurial journey as sustainable ventures move from idea to markets. We leverage an iterative multi-stage process-tracing design to understand the mechanisms whereby 14 different B Corp certified organizations embed purpose before, during and after the certification process. Our analyses reveal three types of venture paths for purpose-driven entrepreneurs, which are shaped by distinct imprinting sequences with three critical sensitive windows playing a pivotal role: the definition of scope of purpose, timing of purpose formalization through B Corp Certification and shifts in the source of feedback. Different imprinters occurring within the critical sensitive windows shape particular imprinting sequences triggering situations of both productive and counterproductive path development. Our results challenge the assumed linear relationship between purpose and purposeful organizing and more specifically the belief that seeking (purposeful) B Corp certification at firm foundation is necessarily productive for society and for the ventures themselves regardless of when the certification is achieved. 相似文献

桥梁工程具有周期长以及范围大等特点。因此,在桥梁施工中任何一个环节出现偏差,都可能诱发裂缝或剥离等问题,最终影响整个桥梁的质量。路面防水工程是桥梁施工项目中的重要环节,防水工程的施工质量将直接影响桥梁结构的整体质量以及使用寿命。因此,在桥梁防水施工过程中,要选择合格的施工材料以及最优的施工方法,从而提高桥梁路面防水工程的施工质量。 相似文献

The effects of in-store music on consumer behavior have attracted much attention in the marketing literature, but surprisingly few studies have investigated in-store music in relation to employees. By conducting a field experiment in eight Filippa K fashion stores in Stockholm, Sweden, we investigate whether it is beneficial for store owners to give employees more opportunities to influence the in-store music. We randomly assigned the stores into a treatment group and a control group, with the employees in the treatment stores having the opportunity to influence the in-store music through an app developed by Soundtrack Your Brand (SYB). The experiment lasted 56 weeks and sales data were also gathered 22 weeks before the experiment, resulting in a total of 4626 observations. Our results show that sales decreased by 6% when the employees had the opportunity to influence the music played in the store, and the effect is driven by a reduction in sales of women's clothing. Interviews with the employees revealed that they had diverse music preferences, frequently changed songs, and preferred to play high-intensity songs. Employees thus seem to make choices regarding the in-store music that reduce sales, implying that store owners might want to limit their opportunities to influence the background music. 相似文献
