对大型土遗址的植物病害研究——以西安阿房宫遗址为例

在植物对土遗址作用的研究中,鲜有就真实的遗址来展开调查,以及讨论植物给土遗址带来的负作用及其机理。为此,本研究选取西安地区大型土遗址秦阿房宫为研究对象,利用现场调查结合样带法、图像分析法并采集土样,开展对遗址区植物分布、根系产生的裂隙和土壤环境的研究。结果表明:造成土遗址病害现象的主要原因为植物根系作用,加之雨蚀、风化作用及人为破坏的叠加作用,使遗址保存面临严重威胁;其中酸枣、臭椿等萌生树种所产生的根劈裂隙及植物根系对土壤环境的影响十分明显。现存土遗址由植物以及风雨作用而引发的主要病害,其类型包含了边缘夯土的基础掏蚀、洞穴遗存、开裂坍塌、冲沟发育、表面剥蚀,这些是阿房宫遗址面临的主要威胁,也是半干旱地区土遗址存在的特有问题。研究结果既有助于揭示植被对土遗址的作用机理,又能为土遗址保护的植物选择提供理论依据和技术支撑。

The Rise in Power of Crown Prince Mohammed bin Salman

Crown Prince Mohammed bin Salman is moving across the international stage as the future King of Saudi Arabia. He has the support of his father, Saudi royals, and the oil income of his country. He also has 10‐year plan he agreed upon with the King called Vision 2030. The three components of the Vision are to diversify the oil‐based economy to include technology and tourism, to make the country the heart of Islam and Arab culture and to become the economic and geographic hub of Asia/Europe and Africa. His rise in power will depend upon his skill in expanding the religious tolerance of Saudi people, the current economic structure of the country, and the education of the youth. He is simultaneously addressing all these challenges in order to cement the country's future sustainability. Suggestions for enhancing his multifaceted impact on his country are provided.     

Linking Heritage Preservation and Community Development: An Assessment of Grassroots Heritage Based Projects as Vehicles for Socio-Economic Development and Sustainable Heritage Preservation in Zimbabwe

This paper engages the practical aspects of linking heritage, in particular, archaeological heritage, with both individual and community economic development. In recent years, there has been growing realisation that culture, inclusive of cultural heritage, can be both a driver and an enabler of economic development, especially in developing countries. However, few documented examples demonstrate the validity of such arguments. The paper explores some practical examples of how, at the grassroots level, individuals and communities are attempting to exploit archaeological heritage sites as well as other cultural and natural heritage resources for income generation in Zimbabwe. The major thrust of the paper is to assess the manner of use and the viability of such ventures. Since the ability of archaeological heritage to generate revenue and support people around the sites has a direct effect on long-term survival of such heritage, ultimately, the paper contributes to the discourse on linking heritage and economic development as well as the theme of sustainable heritage preservation.     

Of Peaceable Kingdoms and Lawless Frontiers: Exploring the Relationship between History,Mythology and Gun Culture in the North American West

The United States is more violent than Canada and it always has been. Even in the face of mass shootings, most Americans remain culturally and politically resistant to the sorts of gun control measures that have long existed in Canada. America’s unique gun culture is embedded in the history, imagery, and especially the mythology of the American frontier. Canada had its own frontier experience and has its own history of gun ownership, but it does not have a parallel gun culture. This article presents a comparative analysis of post-Civil War/post-Confederation frontier history and mythology, and examines the construction of contrasting cultural narratives of America’s “Wild West” and Canada’s “Mild West.” It suggests that US–Canadian differences in gun laws and gun culture—even in the borderlands region of Alberta/Montana—are better explained by the countries’ two different frontier mythologies than by their actual western histories.     

Difference Between the Self and the Heathen. European Imperial Culture in Dutch Missionary Exhibitions, 1909–1957

‘Imperial culture’ is a concept coined by British historiography to describe the influence of imperialism on metropolitan British culture. Although it is now used in other national historiographies as well, it would appear that we have not yet realised the concept's full potential. This article, drawing on recent scholarship emphasising the transnational connections in European imperial cultures, investigates the implications of seeing imperial culture as a European phenomenon and as a European mentality. For this purpose, this article uses the narrative that was propagated at a specific national practice where empire met a metropolitan European society as a case study: missionary exhibitions in the Netherlands in the first half of the twentieth century. Here, Catholic and Protestant missionaries displayed objects from the indigenous, colonised populations who they were trying to convert and hereby legitimised and underpinned imperialism in Dutch culture. However, their significance went deeper than that. This article argues that the missionaries’ narrative transcended the national level and promoted ideas of Christianity as a European religion and civilisation as a European trait. A European community based on religious, cultural, and racial traits was set against a generic non-European heathen world. However, national and denominational frames of reference also remained in place. With this case study, the article explores the possibilities and difficulties that arise from studying imperial culture as a European mentality.     

Cooperative Competition

This article focuses on the collision between the communal-based and individual-based business cultures within the merchant community of Pori. The conflict is analysed by examining divergent petitions, complaints, and statement letters written to and by various authorities at the local, provincial, and national levels during the first half of the 19th century. The case study concentrates on confrontations between a nobleman of Swedish origin, Frans Fredrik Wallenstråle (1771–1857), and members of the local merchant community. The article strives to explain how and why the merchant community and the members of the town council made every possible effort to prevent Wallenstråle from developing his business activities and participating in communal cooperation within the community. In contrast to earlier literature, this article does not concentrate on petitions, their rhetoric, or the interaction between individual and state authorities. It analyses petitions as historical sources that resulted from collisions between the communal, cooperative business culture and vested interests.     

Marketplaces and Morality in Papua New Guinea: Place,Personhood and Exchange

In Papua New Guinea (PNG) more rural people, and especially rural women, earn cash from selling in marketplaces than from any other source. PNG's marketplaces are critical for food security, and for the redistribution of wealth. They are also important meeting places where people gather to see friends, hear the latest news, attend court cases, play cards and be entertained. This introduction to this special issue on ‘Marketplaces and Morality in Papua New Guinea’ reviews the history of PNG marketplaces and their contemporary forms. It charts their transformation from introduced colonial spaces into dynamic Melanesian places, which, as places to buy, sell and socialise, have become pervasive institutions in the lives of both urban and rural Papua New Guineans, and places where people interact with both known and unknown others. From this, marketplaces emerge as important spaces of moral evaluation and contestation in relation to what constitutes morally acceptable exchange and what practices are acceptable in these places. The paper demonstrates that exchange in the marketplace should not be reduced to commodity transactions, and questions assumptions about the types of people marketplaces create. It argues that the country's marketplaces are productive sites to consider ideas of exchange, social relations and social personhood, and that there is a critical need to understand the concrete details of what takes place in contemporary marketplaces.     

Rethinking the role of the arts in politics: lessons from the Négritude movement

The arts can be a powerful tool for emancipation, community building and political expression. This article makes the argument that artistic and cultural expression should be viewed by politicians and policy makers as an effective form of political engagement and an important feedback loop for understanding the political dissatisfaction of the electorate. It draws on one particular historical example, the Négritude movement, to highlight the value and strength of cultural movements in responding to questions of politics and to draw out lessons for current policy makers in recognising the value of culture in effecting political change. Against a contemporary political and scholarly narrative of disaffected citizenship, this article demonstrates that a lack of trust in a political model does not necessarily demonstrate a disinterested citizenry; rather it can suggest a citizenry who have found new and innovative ways to engage. The Négritude movement provides one such historical example.     

How Political Support Influences Red Tape through Developmental Culture

This study examines the interrelationship between external political support, internal organizational factors, and red tape, using a sample of information managers from state health and human service agencies. The study defines a red tape model and tests the model by structural equation modeling method. The study finds that political support has a direct effect on red tape. The higher the political support, the lower the level of red tape. The study also confirms an indirect effect of political support on red tape, mediated by developmental culture. Indirect effect through goal clarity has the correct sign but is not statistically significant. Practical recommendations are made for the political environment to provide the opportunity for managerial reforms that are often advocated.
