Alonso and the Scaling of Urban Profiles

How urban characteristics change with total population, their scaling behavior, has become an important research field since one needs to better understand the challenges of urban densification. Yet urban scaling research is largely disconnected from intra-urban structure, and this seriously limits its operationalization. In contrast, the monocentric model of Alonso provides a residential choice-based theory to urban density profiles. However, dedicated comparative static analyses do not completely solve how the model scales with population. This article bridges this gap by simultaneously introducing power laws for land, income and transport cost in the Alonso model. We show that the equilibrium urban structure of this augmented model matches recent empirical findings about the scaling of European population density profiles and satisfactorily represents European cities. This result is however not compatible with the observed scaling power of housing land profiles, and challenges current empirical understanding of wage and transport cost elasticities with population. Our results call for revisiting theories about land development and housing processes as well as the empirics of agglomeration benefits and transport costs.     

Scenarios of climate change and natural resource development: Complexity and uncertainty in the Nechako Watershed

Climate change and resource development interact to have significant impacts on both natural and human systems within watersheds. It is, however, difficult to conceptualize and communicate these intersections, as climate change and resource development are each independently uncertain and complex. We facilitated a process whereby stakeholders created plausible future scenarios for the Nechako Watershed in British Columbia, Canada. This region is reliant upon, and has been significantly affected by, many types of resource exploitation. During a full-day workshop, 32 stakeholders created scenarios for 2050 envisioning high and low levels of both resource development and climate change. The high and low levels of climate change were based on downscaled projections from global emissions scenarios, and the resource development levels were determined at the beginning of the workshop by the participants. The exercise was educational, and motivated stakeholders to conceptualize plausible future changes and their impacts, and the outcomes should motivate stakeholders to work towards realizing a more desired future. All scenarios (even low-low) were deemed to have significant negative impacts, suggesting that the Nechako Watershed is in a vulnerable state. The complexity of the exercise suggests that more capacity building may be necessary.     

Revisiting interregional wage differentials: New evidence from Spain with matched employer-employee data

This article examines wage differences across Spain's NUTS-2 regions along the entire wage distribution based on matched employer-employee microdata from 2006 to 2014. Unlike previous related studies, we properly control for differences in regional purchasing power parities, which are very large in practice. Although part of the raw regional wage differences observed is explained by differences between regions in productive structures, and, to a much lesser extent, in labor forces, noteworthy, very similar throughout the wage distribution regional differences net of composition effects arise even after controlling for a broad set of individual and firm characteristics.     

Open space preservation in an urbanization context

The objective of this paper is to address the question of open space preservation in an urbanization context. We study the possibility of preserving two different types of open spaces, namely, large open spaces at cities’ outskirts and small intraurban open spaces. Thus, we contribute to the debate of land sharing versus land sparing in an urban context. We analyze these questions by way of a theoretical microeconomic framework that takes into account both households’ preferences for open space and regulators’ interest in the preservation of natural habitat for biodiversity. We compare land use patterns at private equilibrium and when the social planner maximizes social welfare.     

Race and the Pitfalls of Emotional Democracy: Primary Schools and the Critique of Black Pete in the Netherlands

A centrepiece of the Dutch festival of Sinterklaas, the blackface character Black Pete, has met with growing contestation in the past decade over its caricatural representation of people of African descent. Attacks on this national “happy object” elicited a host of majority responses that converged in professing non‐racism. As the celebration is primarily thought of as a children's festival, schools across the Netherlands had to decide whether to maintain, alter or suppress the Black Pete character. This article considers the spatial politics of race that informed school decisions about the festival. We show geographical variation in the distribution between change and non‐change. However, we find that both strategies were justified in the name of respect for “black feelings”, even as majority calls for mutual tolerance between proponents and opponents of Black Pete normatively portrayed multicultural society as conflict free and ultimately strove to disarm anti‐racist critique by framing it as anti‐democratic.     

“Dying out”: conversion and the complexity of neighbourliness on the Polish Belarussian border

This paper addresses the way that religious affiliation and conversion shape ongoing tensions over historical periods of exile, resettlement, exodus and elimination in a small town on the Eastern Polish border. I explore how local Roman Catholic and Eastern Orthodox Christian’s negotiations of a troubled past are materialized and managed through narrating family histories of conversion, In particular, this paper focuses on the compromises that enable mixed faith marriages and the conflicts that emerge over the burial of religious converts. In these negotiations, members of both congregations deploy the local model of “neighbourliness” and the ideal of the borderlander, to greater and lesser success. Day-to-day the practice of considered neighbourliness helps local people to acknowledge and minimize religious and ethnic difference. However, conversion brings the realms of religion and relatedness into conjunction in a risky manner: marriage may offer an opportunity to enhance neighbourly connections, but burial is an event where the tensions over histories of conflict become apparent disrupting neighbourly relations and practices.     

How much does urban location matter for growth?

This paper analyses the effect of location characteristics on urban growth using regression cubic splines. Our empirical analysis shows that in Spain, differences in accessibility to major urban centres and geographic isolation help explain differences in population growth rates across municipalities between 2001 and 2014. Moreover, even though physical proximity to large cities is usually assumed to be closely related to the attractiveness of a municipality, we found that urban population growth is even more related to the joint effect of distance to major centres and agglomeration. In this respect, there seems to be a threshold from which agglomeration diseconomies come into play such that a greater proximity to major cities and/or being localized within a more densely populated area goes against local growth.     

CHARMed PyMca,Part I: A Protocol for Improved Inter‐laboratory Reproducibility in the Quantitative ED‐XRF Analysis of Copper Alloys

This paper describes a protocol for quantification of heritage copper alloys by energy‐dispersive X‐ray fluorescence spectroscopy (ED‐XRF). The protocol, nicknamed CHARMed PyMca, is designed for users who wish to maximize inter‐laboratory reproducibility of quantitative ED‐XRF results for the wide range of copper alloys found in heritage materials. By maximizing reproducibility, this protocol should facilitate collaboration and allow the rigorous use of shared data and databases. The protocol uses free, open‐source, fundamental parameters software called PyMca. PyMca allows for a consistent and transparent application of the fundamental parameters approach independent of the ED‐XRF instrumentation used. The proposed protocol calls for calibration of standardless PyMca results against a set of certified reference materials designed specifically for use with heritage copper alloys, the so‐called copper CHARM set. Finally, this protocol calls for the calibration‐to‐standards to be carried out following a consistent strategy, including error modelling and the incorporation of a validation procedure. A reproducibility study was conducted using CHARMed PyMca and eight different ED‐XRF instruments of six different types. In comparison to a 2010 study conducted according to the same method, CHARMed PyMca showed a dramatic improvement in reproducibility and method sensitivity.
