Finding Vikings in the Danelaw

Historical, artefactual and place‐name evidence indicates that Scandinavian migrants moved to eastern England in the ninth century AD, settling in the Danelaw. However, only a handful of characteristically Scandinavian burials have been found in the region. One, widely held, explanation is that most of these Scandinavian settlers quickly adopted local Christian burial customs, thus leaving Scandinavians indistinguishable from the Anglo‐Saxon population. We undertook osteological and isotopic analysis to investigate the presence of first‐generation Scandinavian migrants. Burials from Masham were typical of the later Anglo‐Saxon period and included men, women and children. The location and positioning of the four adult burials from Coppergate, however, are unusual for Anglo‐Scandinavian York. None of the skeletons revealed interpersonal violence. Isotopic evidence did not suggest a marine component in the diet of either group, but revealed migration on a regional, and possibly an international, scale. Combined strontium and oxygen isotope analysis should be used to investigate further both regional and Scandinavian migration in the later Anglo‐Saxon period.     

The new patron state in South Korea: cultural policy,democracy and the market economy

ABSTRACT

This article explores conceptual frameworks for understanding Korea’s contemporary cultural policy by looking into the historical transformation of the culture-state-market relations in the country. It argues that Korea has become ‘a new kind of patron state’, which emulates the existing patron states in the West firmly within the statist framework and ambitiously renders government-led growth of cultural industries (and the Korean Wave) as a new responsibility of the state. The formation of Korea’s new patron state has been driven by a ‘parallel movement’ consisting of democracy and the market economy, which has defined the political and socio-economic trajectory of Korean society itself since the 1990s. Democracy has been articulated in cultural policy as cultural freedom, cultural enjoyment and the arm’s length principle; meanwhile, the market economy of culture has been facilitated by a ‘dynamic push’ of the state. After discussing the parallel movement, the article points out the tension, ambiguity and contradiction entailed in cultural policy of the new patron state.     

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.     

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.     

Probable human hair found in a fossil hyaena coprolite from Gladysvale cave,South Africa

Until now, the oldest known human hair was from a 9000-year-old South American mummy. Here we report fossil hairs of probable human origin that exceed that age by about 200,000 years. The hairs have been discovered in a brown hyaena (Parahyaena brunnea) coprolite from Gladysvale cave in South Africa. The coprolite is part of a hyaena latrine preserved in calcified cave sediment dated between 195,000 and 257,000 years ago. This find supports the hypothesis that hyaenas accumulated some of the early hominin remains found in cave sites, and provides a new source of information on Pleistocene mammals in the Sterkfontein Valley.     

The early history of the neuroscience of attention-deficit/hyperactivity disorder

Research on the neurobiology and pharmacotherapy of attention-deficit/hyperactivity disorder (ADHD) has grown exponentially since 1980. A reasonable question is whether this research has improved our understanding and treatment of ADHD. This article describes relevant developments that took place roughly between 1900 and 1970. During this time, the efficacy of stimulant therapy for the disorder was established and the symptoms of ADHD were linked to many possible nervous system disorders including in the brain-stem, reticular formation, diencephalon, basal ganglia, frontal lobes, and cortex. In 1970, the catecholamine hypothesis of ADHD was proposed. It is concluded that early theories about the neurobiologic basis of ADHD anticipated core ideas of modern theory.
