Embodied bicycle commuters in a car world

As an initiative to increase cycling, bike to work (BTW) events emphasize a pragmatic approach in which people learn through sensory experience. Pragmatism contends that the lived experience of the commuter within fluid geographies of social and physical conditions informs commuting knowledge and behavior. I researched how bicyclists participate in the 2012 BTW event in Lake Tahoe (USA) and how these experiences facilitate the process of becoming bicycle commuters. My study included participant observations, interviews, video observations, and route mapping. I analyzed this data with thematic and narrative analyses. I find that the BTW event illuminates bicycling, a normally invisible practice in a car world, and creates temporary bicycle-friendly spaces that provide the embodied experience and knowledge of bicycle commuting within context. Through this lived experience, participants can break free from unconscious car-based patterns and become embodied bicycle commuters who engage in active renegotiations of their commuting practices.     

Probabilistic Regionalization via Evidence Accumulation with Random Spanning Trees as Weak Spatial Representations

Spatial clusters contain biases and artifacts, whether they are defined via statistical algorithms or via expert judgment. Graph-based partitioning of spatial data and associated heuristics gained popularity due to their scalability but can define suboptimal regions due to algorithmic biases such as chaining. Despite the broad literature on deterministic regionalization methods, approaches that quantify regionalization probability are sparse. In this article, we propose a local method to quantify regionalization probabilities for regions defined via graph-based cuts and expert-defined regions. We conceptualize spatial regions as consisting of two types of spatial elements: core and swing. We define three distinct types of regionalization biases that occur in graph-based methods and showcase the use of the proposed method to capture these types of biases. Additionally, we propose an efficient solution to the probabilistic graph-based regionalization problem via performing optimal tree cuts along random spanning trees within an evidence accumulation framework. We perform statistical tests on synthetic data to assess resulting probability maps for varying distinctness of underlying regions and regionalization parameters. Lastly, we showcase the application of our method to define probabilistic ecoregions using climatic and remotely sensed vegetation indicators and apply our method to assign probabilities to the expert-defined Bailey's ecoregions.     

South Pacific Agendas in the Quest to Protect Natural Areas

In the South Pacific islands, development assistance agencies, financial institutions, and international NGOs approach conservation in ways that provide opportunities for foreigners to advise islanders about appropriate paths to development. They fund the intergovernmental South Pacific Regional Environment Programme (SPREP), which uses its organizational, legal and discursive powers to create opportunities for their work, and so helps validate inequitable political and economic relationships between the islands and developed regions, ensuring that these continue unchallenged by concerns about environmental degradation. But this outsider–insider dichotomy is too simplistic to describe all the endeavours connected with South Pacific protected areas. Amongst indigenous interests in the islands there is more than a single conservation agenda. The variety of agendas connected to efforts to protect natural areas in the South Pacific islands illustrates that conservation is more than a technical endeavour with a single moral goal. Conservationists’ success in preserving biodiversity and natural areas depends, therefore, upon forming explicit and open alliances with other individuals who, although they may have different aspirations and values, are prepared to work openly and effectively with them to achieve some agreed measures.     

Introducing δSr analysis in archaeology: a demonstration of the utility of strontium isotope fractionation in paleodietary studies

Isotopic methods are widely used in archaeology to investigate paleodiet. Here, we present a new method to identify trophic level in archaeological human populations and to investigate paleodiet. We demonstrate that strontium isotope compositions (reported as δ^88/86Sr) vary in a mass-dependent manner with increasing trophic level and can elucidate paleodiet in archaeological human populations. We present new mass-dependent strontium isotope data from tooth enamel and bone from individuals buried during the Late Intermediate Period (c. AD 1000–1300) in the large cemeteries of Chiribaya Alta, Chiribaya Baja, San Gerónimo, and El Yaral in the Ilo and Moquegua Valleys of southern Peru. We compare these data to radiogenic strontium isotope data (⁸⁷Sr/⁸⁶Sr) and light stable isotope data (δ¹⁵N_col and δ¹³C_col) from the same individuals to investigate geologic variability in strontium sources as well as marine food consumption among the Chiribaya. Our results demonstrate the utility of measurements of strontium isotope fractionation as a new tool for archaeological investigation of paleodiet. Importantly, this new technique can be used to generate paleodietary (δ^88/86Sr) and paleomobility (⁸⁷Sr/⁸⁶Sr) data from the same specimen, minimizing destructive analyses of invaluable archaeological material, and provides a new way to examine paleodiet through hydroxyapatite, which is particularly important when collagen is poorly preserved.     

Living above the shop: home, business, and family in the English "Industrial Revolution"

This article explores the living arrangements and familial relations of small business households in northwest English towns between 1760 and 1820. Focusing on evidence from inventories and personal writing, it examines the homes that such households lived and worked in and the ways in which space was ordered and used: indicating that access to particular spaces was determined by status. This study suggests both the continuance of the "household family" into the nineteenth century (rather than its more modern, "nuclear" variant) and the existence of keenly felt gradations of status within households making it likely that the constitution of "the family" differed according to one's place in the domestic hierarchy.     

Portrayals of Non-North Koreans in North Korean Textbooks and the Formation of National Identity

This article examines the portrayal of non-North Koreans in North Korean textbooks to assess the influences on the formation of North Korean identity, and how such identity formation is important in Kim Jeong-il's retention of power. This study not only looks closely at textual representations; it also examines how political and ideological changes in North Korea had a critical influence on these texts. The study encompasses both lexico-grammatical analysis and the analysis of textual and visual images, based on an examination of six North Korean language textbooks published from 1954 to 2000. It demonstrates that North Korean identity is defined through the portrayal of non-North Koreans, particularly enemy others. The portrayal of non-North Koreans facilitates the formation of a solid North Korean identity – an identity that entails serving their political leaders, remaining vigilant against threats to their country, and liberating South Koreans from poverty and oppression by America and its puppet states.     

Economic geography under postcolonial scrutiny

Because the economy is not found as an empirical object among other worldly things, in order for it to be 'seen' by the human perceptual apparatus it has to undergo a process, crucial for science, of representational mapping. This is doubling, but with a difference; the map shifts the point of view so that viewers can see the whole as if from the outside, in a way that allows them, from a specific position inside, to find their bearings.
