区域旅游发展格局形成要素及演变机制研究——以中部六省为例 总被引:4,自引:0,他引:4
在对区域旅游基本概念梳理的基础上,本文对区域旅游发展格局的要素选择方法和核心要素进行了分析,并以中部六省为例对区域旅游发展格局的形成要素和评价体系进行研究。本文认为,区域经济中的增长极开发模式、点-轴开发模式、核心-边缘开发模式、协作网络开发模式和竞合模式等是可以在区域旅游发展格局演变中借鉴和应用的模式。 相似文献

目的地居民对旅游影响的评价研究——来自山东省的实证检验 总被引:2,自引:0,他引:2
运用Ap和Crompton(1998)提出的旅游影响量表,本文从经济、社会文化、拥挤程度、环境、服务和社区态度等方面实证检验了山东省的目的地居民对旅游影响的感知程度、对旅游影响的态度以及对旅游影响的综合评价,探讨了目的地居民对旅游影响的感知与他们对旅游影响的态度之间的关系。研究结果表明,多数情况下目的地居民对旅游影响的感知与态度之间并不相关。 相似文献

由于观念与技术等问题,我国现行的高校旅游就业统计范围,在专业和行业界定上存在着明显不足,以致人们对于旅游学科在教育体系中的地位以及旅游教育的投入与产出的认识出现严重误解。科学运用旅游卫星账户,参考相关旅游增加值,正确统计高校的旅游就业范围,符合国民经济就业统计的实际需要,也有利于端正人们对旅游就业范围的客观认识。 相似文献

SUMMARYThis essay discusses Hans Aarsleff's long battle to demonstrate the importance of the French and British thinkers of the mid-eighteenth century to the development of modern linguistic thought. Contesting claims that German scholars were the first to develop historicised theories of language, Aarsleff, along with his Princeton colleagues Lionel Gossman and Anthony Grafton, helped pioneer longue durée studies of the history of philology and of historiography that cross national boundaries as well as the so-called Sattelzeit (stretching from about 1780 until 1820). Although the importance of his work was, for a long time, little appreciated by modern intellectual historians, this essay argues that it is time that we fully learned Aarsleff's lessons. 相似文献

Both Canada and the United States have “pivoted” toward Asia in their foreign policy over the past decade, although emphases in those pivots differed between the two countries. The former focuses on an economic pivot initially, the latter on a security one. What factors explain these shifts? What was the magnitude of policy change by both? Utilizing some important theoretical works by Charles Hermann, we discuss the factors that appear to have brought about this policy change toward Asia, outline the actions and activities that both countries have initiated toward Asia in the past decade to illustrate the type and magnitude of policy change that has occurred, and compare some areas of political, economic, and military similarities between Canada and the United States toward this region. Finally, we assess the likely future of these pivots to Asia in light of the change in political leadership within both nations. 相似文献

In 2014, the Supreme Court of Canada ruled that the unelected nature of the Senate is an inherent feature of Canadian parliamentary democracy and is a central pillar of the constitution. Members of the Upper House are appointed by the Governor General, acting on the advice of the Prime Minister. The decision taken by the Prime Minister is not subject to review by Parliament or the provincial legislative assemblies. Patronage appointments have given the Senate a reputation as a dumping ground for political friends and party insiders. In 1989, the province of Alberta enacted the Senatorial Selection Act, arguing that it would serve as a stepping stone for substantive reform to the Senate. The province has held four elections in which the people of the province have chosen senators-in-waiting. This article argues that the Court’s opinion in Reference re Senate Reform undermines the foundation upon which the provincial statute rests. 相似文献

The extent to which Francisco Antonio Moreno y Escandón’s plan of the Viceroyalty of Santafé sparked a revival of cartographical activity has hitherto been overlooked. The Viceroyalty of Santafé was created as a major unit in the Spanish Empire in 1739 and included the present-day countries of Colombia, Ecuador, Venezuela and Panama. Moreno, a high-standing Creole functionary, mapped the region in 1772 in the context of its administrative organization. By drawing attention to Moreno’s official map, I hope to encourage the study of late-colonial and early-republican cartography of the northwestern part of the former Spanish-American dominion and the present-day constituent republics. 相似文献

This paper examines the dynamics of internationalist and nationalist political thought in the formation of International Relations (IR) scholarship in Germany during the early twentieth century. It argues that while liberal internationalism played a significant role in shaping the discipline, IR scholars were often devout nationalists and worked for their government rather than for international peace. German institutions for the study of IR, like their Anglo-American counterparts, were founded in the aftermath of the First World War. Celebrated during the 1920s as ‘bulwarks of democracy’, they were nationalised by the Nazi government, lost their academic profile and since then have been largely forgotten. This paper explains the origins of IR research at the Institut für Auswärtige Politik, based in Hamburg and directed by Albrecht Mendelssohn Bartholdy, as well as at the Deutsche Hochschule für Politik, led by Ernst Jäckh in Berlin. Formally inaugurated in 1923 and 1920 respectively, both institutions drew on pre-war intellectual traditions as well as wartime networks. In light of recent re-appraisals of inter-war IR scholarship in other countries, the German case offers new and important insights into the complex intellectual traditions of what has traditionally been oversimplified as a first ‘great debate’ between ‘idealists’ and ‘realists’. 相似文献

Based on William Morris Davis’ great Transcontinental Excursion of 1912, this article assesses and reviews the Geography by Rail® program (GbR) – a unique, short-term, field-based study abroad experience that takes an uncommon-in-the-US approach to international exploration and fieldwork, incorporating on-the-ground, regional geography-based learning experiences. Though it could be used as such, this is not intended as a “how-to” article, but instead, an examination of how the program’s alternative approach to short-term, field-based learning increases student engagement, enlivens the discipline of geography by championing the regional geography approach, and bridges the physical-human divide in geography. Examples are given of assessment techniques, relevant skills gained by student participants, student feedback received, and potential limitations of such a program. Our main goal rests in demonstrating that by being in the landscape, practicing in it, students often gain a perspective not achievable in the traditional classroom setting. In the regional and romantic geography sense, favoring breadth of learning over depth, we further argue that GbR represents a novel way to accomplish this important-yet-not-often-fostered and, oddly and unfortunately, difficult-to-find-in-geography concept. 相似文献
