- Since the onset of the global economic crisis, financiers and the institutions regulating their behavior have been subject to far-reaching criticism. At the same time, leading geo-scientists have been insisting that future environmental change might be far more profound than previously anticipated. Finance capital has long been a crucial mechanism for melting present solidities into air to create different futures. This article asks what the prospects are for the switching of credit money into green infrastructures-a switching increasingly recognized as necessary for climate change mitigation and (especially) adaptation. Most research into geographies of finance has ignored ecological questions and few contemporary society-nature researchers examine major fixed-capital investments. Unlike those geographers who criticize capitalism without offering feasible alternatives, we take a pragmatic view underpinned by democratic socioenvironmental values and attempt to identify leverage points for meaningful change. This programmatic article identifies reasons and examples to be cautiously hopeful that liquidity can be fixed in less ecologically harmful future infrastructures, thereby addressing crucial extraeconomic challenges for the century ahead.

- There continues to be cross-disciplinary interest in the patterns, extent, and changing contexts of segregation and spatial inequality more generally. The changes are clearly context dependent but at the same time there are broad generalizations that arise from the processes of residential sorting and selection. A major question in U.S. segregation research is how the growth of Asian and Hispanic populations is influencing patterns of segregation and diversity at the neighborhood level. In this article we use a variant of a nearest neighbor approach to map, graph, and evaluate patterns of race and ethnicity at varying scales. We show that using a multiscalar approach to segregation can provide a detailed and more complete picture of segregation. The research confirms work from other studies that segregation is decreasing between some groups and increasing between others, and the patterns, and processes can be described as dynamic diversity. In a series of maps of ethnic clusters and population homogeneity we show how metropolitan areas, represented in this case by Los Angeles, now display patterns of complex living arrangements with multiple groups inhabiting both local neighborhoods and wider community spheres.

- One problem encountered in analyses based on data aggregated into areal units is that the results can depend on the delineation of the areal units. Therefore, a particular aggregation at a specific scale can yield an arbitrary result that is valid only for that specific delineation. This problem is called the modifiable areal unit problem (MAUP), and it has previously been shown to create issues in analyses of clusters and segregation patterns. Many analyses of segregation and clustering use the ratio or difference between a value for an areal unit and the corresponding value for a larger area of reference. We argue that the results of such an analysis can also be rendered arbitrary if one does not examine the effects of varying the geographical extent of the area of reference to test whether the analysis results are valid for more than a specific areal delineation. We call this the part of the MAUP that is related to the area of reference. In this article, we present and demonstrate a multiscalar approach for studying segregation and clustering that avoids the MAUP, including the part of the problem related to the area of reference. The proposed methods rely on multiscalar aggregation of the k nearest neighbors of a location in a statistical comparison with a larger area of reference consisting of the K nearest neighbors. The methods are exemplified by identifying clusters and segregation patterns of the Hispanic population in the contiguous United States.

- It is well established that map projections make it difficult for a map reader to correctly interpret angles, distances, and areas from a world map. A single map projection cannot ensure that all of the intuitive features of Euclidean geometry, such as angles, relative distances, and relative areas, are the same on the map and in reality. This article adds an additional difficulty by demonstrating a clear pattern of naïveté regarding the site at which a route that crosses the edge of a world map reappears. The argument is that this naïve understanding of the peripheral continuation is linear, meaning that the proposed continuation is along the straight line that continues tangentially to the original route when it crosses the edge. In general, this understanding leads to an incorrect interpretation concerning the continuation of world maps. It is only in special cases—such as radial routes on a planar projection and peripherally latitudinal routes on a cylindrical or pseudocylindrical projection with a normal aspect—that the actual peripheral continuation of the world map is linear. The data used in this article are based on questionnaires administered to 670 children aged nine to fifteen and eighty-two adults. This naïve understanding of the peripheral continuation, which leads to errors, was found to be entirely dominant among the children, regardless of the projection, and was clearly observed among the adults when the projection was cylindrical with a normal aspect.

From Middle Ground to Common Ground : Self-Management and Spaces of Encounter in Organic Farming Networks
- 2015
-

- This article deploys the anarchist notion of self-management to critically investigate the global organic farming network World-Wide Opportunities on Organic Farms (WWOOF) as an initiative that offers insights into the possibilities and challenges of encounter. WWOOF facilitates the giving of food, accommodation, and hands-on learning experiences for volunteers, in exchange for their labor on organic farms. It operates as a moneyless sharing economy, designed as a site of mutual learning and cultural exchange. Literatures on encounter divide between brief tourist encounters of difference and everyday encounters in diverse, usually urban, communities. In linking these two bodies of work, I argue that the principle of self-management, as conceived by anarchist thinkers, can help develop a unified, critical framework for making sense of encounter event spaces. This adds important nuance to theorizations of encounter by recognizing the entwinement of the intimate and the structural, foregrounding the capacity of people to autonomously create shared spaces of interdependence. The case study indicates that structural contradictions and inequalities in voluntary relationships within statist-capitalist systems can seriously undermine otherwise promising interpersonal encounters. By articulating self-management as a tool for both analyzing and producing spaces of encounter, this article offers new possibilities for a more holistic and unified analytical framework.

Patterns of socioeconomic segregation and mix in the capital cities of fast-track reforming post-socialist countries

- Socioeconomic disparities have been rising on both sides of the Atlantic for the last forty years. This study illuminates the relationship among economic inequality, other contextual and institutional factors, and socioeconomic intraurban segregation in Eastern Europe. We draw our empirical evidence from the capital cities of so-called fast-track reforming postsocialist countries: Estonia, Hungary, Lithuania, Poland, and the Czech Republic. The analysis consists of two stages. First, we use the traditional indexes of segregation to assess the global levels of socioeconomic segregation in the case cities. Second, we investigate the global patterns and local geographies of socioeconomic residential intermixing and introduce a typology of neighborhoods based on the socio-occupational composition of their residential tracts. Despite rapidly growing income inequality, the levels of socioeconomic segregation in the postsocialist city are either low or very low. The scale of segregation differs between the cities and the patterns of residential intermixing in the large cities of central and Eastern Europe are fundamentally different from those found in the Baltic states. The results lead to two important conclusions. One is that the link between socioeconomic distance and spatial distance in postsocialist cities is moderately sensitive to the level of economic inequality and to other contributory factors. The other key finding is that inertia effects have offset the immediate catalyzing effect of economic liberalization, globalization, and growing socioeconomic inequality on the patterns of segregation, at least in the first decade after the collapse of socialism.

Nature, Poetry, and Public Pedagogy: The Poetic Geographies of the Khmer Rouge

- Between 1975 and 1979, more than 2 million men, women, and children died in what has become known as the Cambodian genocide. In just under four years, approximately one-quarter of the country's prewar population succumbed to arbitrary murder, torture, detention, starvation, and disease. Amidst these acts of destruction, however, the Communist Party of Kampuchea (CPK; the Khmer Rouge) advanced various pedagogical practices, including the promotion of poetry. Superficially, poems produced by the Khmer Rouge are literary forms of propaganda. Such a conclusion is incomplete. Through a reading of Khmer Rouge–era poetry, this article contributes to two themes in geography: fictive and public pedagogy. We argue that the Khmer Rouge used poetry as a form of public pedagogy. More specifically, Khmer Rouge–era poetry presented nature as the fulcrum on which society was to be transformed. The cultivation of a proper political consciousness required the nurturing of a community identity of what Democratic Kampuchea was to become. This argument is developed in five sections. First, we provide a brief overview of literary geographies. We then consider the transformative power of public education. Third, we provide an overview of educational policies under the Khmer Rouge. This is followed by a discussion of nature as conceived by the CPK. Our main empirical analysis of Khmer Rouge poetry is presented in the fifth section. Finally, we conclude with a consideration of the politics of creative interventions as a form of public pedagogy.

Using Satellite Data on Nighttime Lights Intensity to Estimate Contemporary Human Migration Distances

- © 2017 by American Association of Geographers. For well over a century, migration researchers have recognized the lack of adequate distance measures to be a key obstacle for advancing understanding of internal migration. The problem arises from the convention of spatially defining migration as the crossing of administrative borders. Because administrative regions vary in size, shape, and settlement patterns, it is difficult to tell how far movers go, raising doubts about the generalizability of research in the field. This article shows that satellite data on nighttime lights can be used to infer accurate measures of migration distance. We first use the intensity of nighttime lights to locate mean population centers that closely correspond to mean population centers calculated from actual population data. Until now, locating mean population centers accurately has been problematic, as it has required highly disaggregated population data, which are lacking in many countries. The nighttime lights data, which are freely available on a yearly basis, solve this challenge. We then show that this information can be used to accurately estimate migration distances.

HIGH-CONTRAST IMAGING OF INTERMEDIATE-MASS GIANTS WITH LONG-TERM RADIAL VELOCITY TRENDS

Tidskriftsartikel (refereegranskat)abstract
- A radial velocity (RV) survey for intermediate-mass giants has been in operation for over a decade at Okayama Astrophysical Observatory (OAO). The OAO survey has revealed that some giants show long-term linear RV accelerations (RV trends), indicating the presence of outer companions. Direct-imaging observations can help clarify what objects generate these RV trends. We present the results of high-contrast imaging observations of six intermediate-mass giants with long-term RV trends using the Subaru Telescope and HiCIAO camera. We detected co-moving companions to gamma Hya B (0.61(-0.14)(+0.12)M(circle dot)), HD 5608 B (0.10 +/- 0.01M(circle dot)), and HD 109272 B (0.28 +/- 0.06M(circle dot)). For the remaining targets (iota Dra, 18 Del, and HD 14067), we exclude companions more massive than 30-60 M-Jup at projected separations of 1 ''-7 ''. We examine whether these directly imaged companions or unidentified long-period companions can account for the RV trends observed around the six giants. We find that the Kozai mechanism can explain the high eccentricity of the inner planets iota Dra b, HD 5608 b, and HD 14067 b.
