This paper explores the relationship between national iconography, banal nationalism and conceptions of the state. It begins by reviewing scholarship on visual culture associated with official products of the state: namely, stamps and money. This reveals a preoccupation with content analysis and a tendency to assume state control over the symbolic content of money (and stamps) without clarifying the nature of design processes, the nature of state involvement in these processes, or how ‘the state’ is being conceptualized. The paper addresses these lacunae, beginning with an examination of approaches to banknote design and clarification of the role of the state in these processes. This analysis reveals that non-state actors and institutions are frequently responsible for this key mechanism of official iconographic representation and this, in turn, supports calls for a reassessment of the concept of the state. After outlining an alternative conception of the state, as an idea that produces ‘state effects’ rather than an empirical entity separate from society, the value of this concept is illustrated by showing how it can explain banknote production in the stateless nation of Scotland. The revelation that commercial banks can be co-constitutive of state effects – things like banknotes, national institutions, iconography and identity – challenges presumptions of a discrete state that controls its own representation and the regulation of society.  相似文献

Industrial land is under transition globally. Insights into this transition are important to plan a sustainable future. Since industrial land follows parcel shapes and the transition process requires multi-year data to observe the impacts of such changes, multi-year vector data should be used to analyse industrial land transition. This paper presents a framework to analyse path-dependent regional industrial land transition processes using vector data. A step by step instruction is presented. In the analysis, the changed percentages of land use in the surroundings of appeared or disappeared industrial land are visualized. The visualized surrounding land use compositions give planners an idea on what causes land use transitions, the most frequent transition forms and their impacts on the surroundings, purely from a land use point of view to reduce data collection efforts. The North Brabant region in the Netherlands is used as a case study. The region is split into urban and non-urban areas to show the generic applicability of this framework.  相似文献

Academic research on contemporary Dutch nationalism has mainly focused on its overt, xenophobic and chauvinist manifestations, which have become normalised since the early 2000s. As a result, less radical, more nuanced versions of Dutch nationalism have been overlooked. This article attempts to fill this gap by drawing attention to a peculiar self‐image among Dutch progressive intellectuals we call anti‐nationalist nationalism. Whereas this self‐image has had a long history as banal nationalism, it has come to be employed more explicitly for political positioning in an intensified nationalist climate. By dissecting it into its three constitutive dimensions – constructivism, lightness and essentialism – we show how this image of Dutchness is evoked precisely through the simultaneous rejection of ‘bad’ and enactment of ‘good’ nationalism. More generally, this article provides a nuanced understanding of contemporary Dutch nationalism. It also challenges prevalent assumptions in nationalism studies by showing that post‐modern anti‐nationalism does not exclude but rather constitutes essentialist nationalism.  相似文献

In this article, we address the international dimension of Stellenbosch University (SU) during the apartheid era, most notably during the academic boycott of South African universities between the early 1960s and the early 1990s. Based on information gathered from the documentary sources of the university and interviews with key role players at the university, the findings of the research will put some of the well-established hypotheses on South Africa’s academic isolation and an increasing localism in higher education during that period into perspective. The article will show that prior to 1990 there were different kinds of international activities going on at SU, despite the academic boycotts.  相似文献

This article investigates the Anglo–Dutch scholar and diplomat Isaac Dorislaus's sole published work, Praelium Nuportanum (PN; 1640), on the battle of Newport in 1600. After presenting some new or little known information about the work, it discusses PN's intellectual context and concludes that the work is a reminder of successful Anglo–Dutch cooperation in the past, of Dutch indebtedness to English assistance, and the Republic's importance as an ally for England, all relevant to the negotiations running in 1640 for an Orange–Stuart wedding, and their backgrounds in the British Civil Wars and Anglo–Spanish–Dutch relations at the time. After the troubles ensuing from Dorislaus's Cambridge lectures on Tacitus in 1627, PN shows the author reconciled with the Court and the Laudian faction. With respect to style and content, PN appears clearly Tacitist in style, with many direct quotations from Tacitus, but this Tacitism operates more on a literary than a political level. Much of PN's historical content is a reworking of Francis Vere's Commentaries (published 1657). From the perspective of the Protestant ‘Anglo–Scoto–Dutch public sphere’ recently discussed in the scholarship, PN might perhaps be read as a warning of the gradual emergence of an Anglo–Dutch Calvinist–parliamentarian ‘realm’ as a force opposing the Crown.  相似文献

This article argues that Henry Savile's widely admired Tacitus of 1591 should not be read as an implied call for a more aggressive English stance against Spanish advances on the Continent (as one recent article suggests), but precisely for a more restrained and prudential approach. Secondly, it calls into question the generally accepted view that Robert Devereux, Earl of Essex, played a prominent role in the composition of the book. It argues that in reconstructing the work's original intellectual context and especially that of the supplement The Ende of Nero and the beginning of Galba, the main emphasis should not be on Essex's political and military career, but on that of his stepfather Robert Dudley, Earl of Leicester. The article provides an investigation (as far as the surviving information allows) of the background in Continental politics and political thought in relation to the text of The Ende, which suggests that it should primarily be read from the perspective of the unsuccessful English intervention in the Low Countries in 1585–88.  相似文献

When estimating spatial regression models by maximum likelihood using spatial weights matrices to represent spatial processes, computing the Jacobian, ln(|I ? λW|), remains a central problem. In principle, and for smaller data sets, the use of the eigenvalues of the spatial weights matrix provides a very rapid resolution. Analytical eigenvalues are available for large regular grids. For larger problems not on regular grids, including those induced in spatial panel and dyadic (network) problems, solving the eigenproblem may not be feasible, and a number of alternatives have been proposed. This article surveys selected alternatives, and comments on their relative usefulness, covering sparse Cholesky and sparse LU factorizations, and approximations such as Monte Carlo, Chebyshev, and using lower‐order moments with interpolation. The results are presented in terms of component‐wise differences between sets of Jacobians for selected data sets. In conclusion, recommendations are made for a number of analytical settings. Al estimar modelos de regresión espacial con el método del máxima verosimilitud (máximum likelihood) y usando matrices de pesos espaciales para representar procesos espaciales, cálculo del término jacobiano (jabobian)—ln(| I ?λ W |)‐ sigue siendo un problema central. En principio, y para bases de datos más pequeñas, el uso de los valores propios (eigenvalues) de la matriz de pesos espaciales proporciona una solución muy rápida. Los eigenvalues analíticos para retículas o grillas grandes y regulares son ya conocidos. Para problemas más grandes, que no se presentan en mallas regulares ‐incluyendo aquellos que se inducen en problemas de paneles espaciales y en problemas de (redes) diádicas‐, es posible que resolver el eigenproblem no sea posible. Este artículo estudia una selección de alternativas y comenta acerca de su relativa utilidad. Se cubren las facorizaciones de tipo Cholesky disperso (sparse Cholesky) y de tipo LU dispersas (sparse LU), las aproximaciones Monte Carlo, y Chebyshev, así mismo se utiliza momentos de bajo‐orden (lower‐order) con interpolación. Los resultados se presentan en términos de diferencias de componentes entre sets de términos jacobianos para bases de datos seleccionadas. En conclusión, se hacen recomendaciones para una serie de contextos analíticos. 当采用表征空间过程的空间权重矩阵对空间回归模型进行最大似然估计时,雅可比矩阵ln(|I?λW|)的计算仍是核心问题。对于小数据集,原则上可利用空间权重矩阵的特征值提供一种快速的解决方案,对于大型规则格网数据特征值分析同样有效。但对于不规则格网大型问题,包括从空间面板和二元(网络)问题中引伸的问题,利用特征值的解决方案可能不适用,对此学术界提出了多种可选替代方案。本文选取已有的几种替代方案并评论各自的相对有效性,其中包括稀疏Cholesky分解和稀疏LU分解法,Monte Carlo和 Chebyshev近似模拟法以及低阶矩插值法。结果以所选数据集雅可比矩阵间特定组份的差异方式显示。最后,推荐了一些分析设定。  相似文献

According to the 13th century Icelandic Saga writer Snorre Sturlasson, there was a marketplace (in old Norwegian: Kaupstadir) in the T?nsberg area by the end of the 9th century. The origin of the medieval town of T?nsberg has therefore been much discussed in the light of this statement. Viking Age and early medieval settlements often lack material datable by archaeology alone. In T?nsberg radiocarbon dating has been used to distinguish between Viking Age deposits and medieval deposits, when stratigraphy alone does not state the differences. However, this dating method has produced various results and there is obvious need for a local calibration.  相似文献
