Measuring the Scale of Segregation Using k‐Nearest Neighbor Aggregates

Nearly all segregation measures use some form of administrative unit (usually tracts in the United States) as the base for the calculation of segregation indices, and most of the commonly used measures are aspatial. The spatial measures that have been proposed are often not easily computed, although there have been significant advances in the past decade. We provide a measure that is individually based (either persons or very small administrative units) and a technique for constructing neighborhoods that does not require administrative units. We show that the spatial distribution of different population groups within an urban area can be efficiently analyzed with segregation measures that use population count‐based definitions of neighborhood scale. We provide a variant of a k‐nearest neighbor approach and a statistic spatial isolation and a methodology (EquiPop) to map, graph, and evaluate the likelihood of individuals meeting other similar race individuals or of meeting individuals of a different ethnicity. The usefulness of this approach is demonstrated in an application of the method to data for Los Angeles and three metropolitan areas in Sweden. This comparative approach is important as we wish to show how the technique can be used across different cultural contexts. The analysis shows how the scale (very small neighborhoods, larger communities, or cities) influences the segregation outcomes. Even if microscale segregation is strong, there may still be much more mixing at macroscales.     

A feminist-phenomenology of women’s activism against hydropower plants in Turkey’s Eastern Black Sea region

Taking a feminist-phenomenological perspective of the body, this article provides an empirically grounded analysis of the embodied subjectivity of women in the movement against hydropower plants (HPPs) in the culturally and spatially specific context of the Eastern Black Sea region of Turkey. Informed by a feminist engagement with Merleau-Ponty’s concepts of ‘the body-subject’, ‘the flesh’ and Einfühlung, the article places subjectivity within a relational ontology of sentience and intelligence in which corporeal experiences, senses and affects condition cognitive and agential processes. Bodily senses and affects are thus treated as media of subjectivity. The relationship between water and identity, established through memory, heritage and history, is also produced and/or conserved by the embodied relation between women’s bodies and bodies of water, within the connective ‘flesh’ of the physical world. The case of the Eastern Black Sea demonstrates how political subjectivity of women in the movement against HPPs is conditioned by an intimate embodied relationship with river waters that is sustained by a series of sensory-affective experiences. Their statements emphasize, over and over again, an interconnectedness with the rivers, which makes the cause of anti-HPP struggle vital and urgent for them. This feeling of urgency is a source of women’s radicalism in opposing HPPs. The article maintains the female subject as embodied and transversal, and stresses the centrality of corporeal experience, sense and affect in formation of political subjectivity. By developing a body-centred feminist-phenomenological approach to political subjectivity, it introduces a novel way of analysing women’s activisms within and beyond environmental movements.     

Collaborative Networks for Effective Ecosystem‐Based Management: A Set of Working Hypotheses

Ecosystem‐based management (EBM) represents a comprehensive approach to better govern the environment that also illustrates the collaborative trend in policy and public administration. The need for stakeholder involvement and collaboration is strongly articulated, yet how and for what purposes collaboration would be effective remains largely untested. We address this gap by developing and evaluating a set of hypotheses specifying how certain patterns of collaborations among actors affect their joint ability to accomplish EBM. Content analyses of management plans drawn from five EBM planning processes in Sweden are combined with analyses of the collaborative networks through which these plans have been developed. Our results indicate that system thinking and the ability to integrate across different management phases are favored by collaborations between different kinds of actors, and by project leaders being centrally located in the networks. We also find that dense substructures of collaboration increase the level of specificity in the plans in regards to explicating constraints on human activities. Having many collaborative ties does however not enhance the overall level of specificity. Our results also show that different network characteristics can give rise to similar EBM outcomes. This observed equifinality suggests there is no single blueprint for well‐performing collaborative networks.     

Meaning in a Changing Context: Towards an Interdisciplinary Approach to Authorial Revision

Summary

In this article, I seek to develop a genetic/diachronic approach to the phenomenon of authorial revision, and to the interpretation of texts that exist in multiple versions. In all such cases, the reconstruction of textual meaning cannot be separated from the reconstruction of the process through which the text in its ‘final’ form came into being; furthermore, an understanding of the author's intentions in (re)writing cannot be entirely separated from an understanding of his/her motives for (re)writing. This article is divided into three sections. In the first section, I consider recent trends in editorial and literary theory that aim at characterising texts in terms of processes rather than products, in order to uphold the equal dignity of each version without losing sight of its connectedness to other stages in the history of the text. In the second section, I discuss how Quentin Skinner's views on meaning and context apply to cases of authorial revision, and I suggest that some key aspects of Skinner's contextualism need to be reconsidered. In the concluding section, I focus on a case study in order to demonstrate the operational value of such a genetic and motive-based approach to authorial revision: more particularly, I seek to show how a close examination of Jean Bodin's rewriting practices in the Methodus (1566–1572) and the République (1576) can throw new light on his shift from a concept of limited sovereignty to one of absolute sovereignty.     

The Role of Government Policies and Strategies Behind the Shrinking Urban Core in an Expanding City Region: The Case of Izmir

Over the last few decades, the term urban shrinkage has come to be accepted as a valid concept in international academic circles, and has gradually gained importance, with its causes the subject of well-documented discussion. While previous discussions of urban shrinkage have directed attention to cities shrinking as a whole, recent research started to recognize the case of shrinkage in growing cities and regions. As such, recent discussions of urban shrinkage indicate that patterns of shrinkage vary considerably from city to city, and from sub-region to sub-region, with the importance of local dynamics in responding to changing economic pressures given much consideration. Recent studies have tended to disregard the role of government policies and strategies put in place to facilitate the adaptation of the urban economies to the new conditions. Taking Izmir as an example, being a fast-growing metropolitan region in Turkey, this paper presents evidence of government policies and strategies aimed at enhancing the development of peripheral areas that have led to shrinkage of the metropolitan core. This paper focuses on this experience and discusses its implications.     

Chemical analyses of the earliest pigment residues from the uttermost part of the planet (Beagle Channel region,Tierra del Fuego,Southern South America)

This paper presents the results of chemical analyses of the organic and inorganic fractions of pigment residues found in three archaeological sites located in the Beagle Channel region, Tierra del Fuego, Southern South America. Twenty-one archaeological samples have been analysed through XRD, SEM–EDX, FT-IR and GC–MS in order to characterise their inorganic colouring components and to search for the presence of organic substances used as binders. Lipids found in some samples are considered as potential binders. These organic components are compared to those found in archaeological sediment samples from the same layers where the pigments have been found, in order to search for potential taphonomic contaminations of the latter by the former. Results show that such contaminations are unlikely, hence the lipid contents are deemed of anthropic origin. The pigment sample results are also compared to data from analyses of natural sediment samples collected in several localities of the Beagle Channel in order to search for potential natural pigment sources. Results show that organic and inorganic components of these sediments are not the same than those present in the archaeological pigment samples, hence the pigment raw material sources have not been yet located. All these data provide for the first time evidence of the existence of ancient activities of pigment sourcing and paint preparation with organic binders which range from 6000 BP to 1900 BP in the southernmost region of the planet.
