The Taste of the Eye and the Sight of the Tongue: the Relations between Sight and Taste in Early Modern Europe

This article examines the articulation between the senses of taste and sight through the representations of their organs, the tongue and the eye, in early modern Europe. The relationship between taste and sight first brings to mind gastronomical aesthetics, and the part played by the eye in the relish of beautifully presented dishes. The first part of this article is therefore devoted to exploring the taste of the eye (or the foretaste of sight) and highlights the harmony of taste and sight in early modern cuisine. However, the forms of reciprocity between taste and sight cannot be reduced to the sole figure of culinary aesthetics, which tends to blur the other multiple modalities that this sensorial association could reveal. The second part, the sight of the tongue (or the invisibility of taste), thus examines more complex layers of the relationship between the sense of sight and the taste organ, through a study of the representations of the tongue and of the gaping mouth in early modern visual culture. Drawing on early modern textual and iconographic resources and exploring: cookbooks; physiognomic works; conduct books; and also engravings and paintings related to the culinary arts, the seven deadly sins, and representations of madness and the fool in early modern visual culture, this essay argues that examining the representations of the sense organs is a suggestive way to explore the relationship between the senses.     

Local Influence Analysis in AB–BA Crossover Designs

The aim of this article is to develop methodology for detecting influential observations in crossover models with random individual effects. Various case‐weighted perturbations are performed. We obtain the influence of the perturbations on each parameter estimator and on their dispersion matrices. The obtained results exhibit the possibility to obtain closed‐form expressions of the influence using the residuals in mixed linear models. Some graphical tools are also presented.     

Drivers of biodiversity patterns in parks of a growing South American megacity

How urban habitats contribute to biodiversity conservation is a key challenge in a rapidly urbanising world. Urban parks can provide important habitats for native species, but previous studies are geographically biased; fast growing megacities, in particular in South America, are clearly understudied. To assess habitat functions and underlying drivers in parks of Santiago de Chile, we analysed the assemblages of wild growing plant species in two ubiquitous park habitat types (grasslands, wooded areas) in 15 parks (150 plots) along an urban-rural gradient. We first used linear contrasts to compare species richness, beta diversity and the proportion of introduced species. We then tested for the explanatory value of environmental variables operating at different spatial scales (plot, park, urban matrix). Unlike in most previous studies, biodiversity patterns were not related to the position of the parks on the urban-rural gradient. Introduced species, mostly from Europe, generally dominated both habitat types (>90 %). Socio-economic (population growth or density), but not spatial, variables were retained in most models. Maintenance intensity was most influential in predicting species assemblages, complemented by park age in wooded areas. A high proportion of European grassland species indicates a trend of homogenisation in park grassland at a cross-continental scale. We conclude that habitat functions of urban parks for native species that have been mainly demonstrated for Europe cannot be generalised to South American megacities. This highlights the need for innovative and locally appropriate conservation approaches (e.g., re-introduction of native species) to foster biodiversity functions in urban parks of South American megacities.

Could diamonds become an investor’s best friend?

Currently, the role of diamonds in the global financial system is under intense discussion in the financial media because individual investors and portfolio managers have begun to consider them as potential investment assets. To address the growing interest in diamonds, this article examines the historical performance of investments in various diamond quality grades. Furthermore, it investigates their relation to stock market and currency risk. Specifically, we focus on two important practical investment questions: Can diamonds function as a hedge or a safe haven against stock market volatility or fluctuations of the US dollar? Can diamonds be regarded as effective diversifiers in a stock or a currency portfolio context? Key findings are as follows: (1) The investment performance of diamonds is lower than the one of gold and silver. (2) Diamonds have only acted as a weak hedge and a weak safe haven against stock market downturns and currency risk associated with the US dollar. (3) Within global stock and currency portfolios, 1.0 carat fine diamonds show valuable diversification potential in that they can increase portfolio performance to an economically significant extent. Interestingly, this final result is fairly robust to the choice of performance measure.     

Mediating Effects Between Objective and Subjective Indicators of Urban Quality of Life: Testing Specific Models for Safety and Access

Enhancing the urban quality of life (QoL) is an explicit policy goal of many countries, yet it is rarely studied using models that relate objective measures of the urban environment to the subjective evaluations of residents. It thus often remains unclear how planning interventions in the urban environment may influence residents’ satisfaction with their living conditions. In particular, during periods of significant urban growth, such as those recently observed in Switzerland, which result in diverse, unwanted threats to the local QoL (e.g., loss of green spaces, traffic congestions, and fear of crime). This study uses data from a sample of 1,693 residents that participated in a postal survey about urban QoL. The responses were combined with objective attributes of residential conditions, using geographic information systems. Structural equation models were calibrated to examine the direct and indirect effects of important indicators of urban QoL, namely safety in public spaces and access to central urban facilities. The study sheds further light on the mediating effects between objective characteristics and subjective evaluations that influence the urban QoL. The results showed predominantly low correlations between objective characteristics and subjective evaluations of urban QoL, which confirmed the findings of the few previous studies on this topic. Surprisingly, this study also found a strong link between objective access and perceived accessibility. This relation was explained by the spatial scope of the study region and suggested that the scale discordance theory should be tested in future research. The findings implied that variations in objective measures do not reliably represent differences as evaluated by residents.     

Trade Credit and the Propagation of Corporate Failure: An Empirical Analysis

Using an exhaustive data set on claims held by trade creditors (suppliers) on failed trade debtors (customers), we quantify the importance of trade credit chains for the propagation of corporate bankruptcy. We show that trade creditors experience significant trade credit losses due to trade debtor failures and that creditors' bankruptcy risks increase in the size of incurred losses. By exploring the roles of financial constraints and creditor‐debtor dependences, we infer that the trade credit failure propagation mechanism is driven by both credit losses and demand shrinkage. Finally, we show that the documented propagation mechanism constitutes a significant part of the overall bankruptcy frequency, suggesting that it has measurable implications for the aggregate level.
