We use LASSO methods to shrink, select, and estimate the high‐dimensional network linking the publicly traded subset of the world's top 150 banks, 2003–2014. We characterize static network connectedness using full‐sample estimation and dynamic network connectedness using rolling‐window estimation. Statically, we find that global bank equity connectedness has a strong geographic component, whereas country sovereign bond connectedness does not. Dynamically, we find that equity connectedness increases during crises, with clear peaks during the Great Financial Crisis and each wave of the subsequent European Debt Crisis, and with movements coming mostly from changes in cross‐country as opposed to within‐country bank linkages. 相似文献

This article focuses on the material and discursive constructions of nature and children in the city. While dominant representations and idealizations of nature and childhood depend on the binary logic of the nature/culture and rural/urban divide, there is also a simplification and romanticization of nature in children's geographies and a lack of children and their spaces in urban political ecology. We argue that children and nature in cities need to be removed from a binary model of being and attended to in more nuanced ways in urban political ecology and children's geographies. In this regard, we suggest that both nature and children in cities need to be queered. We need to ask how the production of urban spaces (re)creates particular romantic and idealized relations with natures that reify the binaries between nature/culture, and male/female through a heteronormative framework. The purpose of this article is to bring the critical nature–society theories of urban political ecology into conversation with work in children's geographies that explores the ‘nature' of childhood, and in doing so queer the relationship between children and nature. Drawing on research on queer ecologies, and queered childhoods, we aim to provide a framework to rethink and queer both nature and children in cities. 相似文献

This paper assesses the potential implications on off-season tourism of enhancing the cultural offer of Rimini, a popular Italian seaside holiday destination hosting about 12 million overnight stays per year. Since more than 9 million of these stays are concentrated in the summer season, in the last 20 years. Rimini has been undergoing a policy of seasonality smoothing, which mainly pivots around business and cultural tourism. This assessment has been carried out through discrete choice experiments submitted to a sample of about 800 tourists who visited Rimini outside the summer months. Since tourism can be viewed as a composite good, which overall utility depends on how the component characteristics are arranged, the choice experiments allow to disentangle the importance and the willingness to pay of tourists for different attributes of the holiday. The choice model incorporates a number of possible changes to actual tourism features (which are also the subject of public debate), including them in hypothetical alternative “holiday packages”. The conditional logit analysis of the choice experiments can highlight any synergy or trade-off between cultural and business tourism. Results suggest that business and leisure tourists share many features related to the use of the territory, while there are important trade-offs between these two groups and cultural tourists. Since business tourists have a higher willingness to extend their stay, a softer budget, and their demand is also complementary to the demand of summer tourists (Brau, Scorcu, & Vici, 2009), from the destination point of view investing in this market segment would be the best option. Although a “second best”, however, cultural tourists share with the local population of Rimini many aspects of the demand of territory (Figini, Castellani, & Vici, 2009). Hence, cultural tourism can play a fundamental role in the intermediate season as a tool for smoothing seasonality, to diversify investments and to give value to the city’s cultural heritage. 相似文献

We conduct the first study to examine the fetal health impact of light pollution based on a direct measure of skyglow, an important aspect of light pollution. Using an empirical regularity discovered in physics (called Walker's law) as an instrumental variable, we address the potential endogeneity problem associated with the skyglow variable. We find evidence of reduced birth weight, shortened gestational length, and increases in preterm births. Specifically, increased nighttime brightness, characterized by being able to see only one‐fourth to one‐third of the stars that are visible in the natural unpolluted night sky, is associated with an increase of 1.48 percentage points in the likelihood of a preterm birth. Our study adds to the literature on the impact of early‐life exposure to pollution, which so far has focused primarily on air pollution. Our study has important policy implications regarding the necessity of minimizing skyglow that is, for example, contributed by streetlights. 相似文献

This paper assesses whether and how common characteristics of jury members or peer voters affect the outcomes of voting systems.
In particular, we analyze to what extent these common features result in voting bias. We take as a case study the Eurovision
Song Contest for which an extensive amount of historical data is available. In contrast to earlier studies we analyze the
impact of common factors on the bias individually for each country, which is necessary to substantiate the publicly debated
accusations of regional block voting by certain groups of countries. We establish strong evidence for voting bias in the song
contest on the basis of geography, even after correction for culture, language, religion and ethnicity. However, these effects
do generally not correspond to the usual accusations. We believe that our findings extend to all instances where groups of
jury members or peer voters share certain common factors, which may cause voting bias. It is important to identify such structures
explicitly, as it can help avoiding bias in the first place.

Abstract Public sector organizations are simultaneously subject to three types of environmental pressure: institutional, economic and political. How do these pressures influence the strategic behaviour of public organizations when confronted with efficiency-oriented reforms? We focus on the strategic behaviour of Swiss municipalities facing the amalgamation wave: a reform characterized by a strong economic rationale. Results confirm that the success of reforms depends not only on its matching with economic underpinnings. It is also necessary to take the political leadership and the responsibility of reform implementation. 相似文献
