Following a right cerebral stroke, the German artist Anton Raederscheidt produced a remarkable series of self-portraits that depicted his severe visual neglect and gradual recovery. These distorted images, like those drawn by others with this disorder, inform us about lateral balance in art and why it is common in the art of cultures separated in time and space. After describing how artists in various cultures have employed lateral balance, I present Arnheim's view that this aspect of art is the result of visual forces generated by the brain. Following a brief history of visual neglect, I present evidence that this disorder provides us with clues to the origin of the visual forces responsible for lateral balance in art. The relevant brain mechanisms control exploration of visual space by integrating orienting movements with visual spatial information. The prevalence of lateral balance in art becomes understandable when we consider that these brain mechanisms evolved to promote survival in our vertebrate ancestors. I end with a speculative neurological account of the aesthetics of lateral balance--why it is pleasing and its absence is displeasing.  相似文献

Despite its rich tradition, there are key limitations to researchers' ability to make generalizable inferences about state policy innovation and diffusion. This paper introduces new data and methods to move from empirical analyses of single policies to the analysis of comprehensive populations of policies and rigorously inferred diffusion networks. We have gathered policy adoption data appropriate for estimating policy innovativeness and tracing diffusion ties in a targeted manner (e.g., by policy domain, time period, or policy type) and extended the development of methods necessary to accurately and efficiently infer those ties. Our state policy innovation and diffusion (SPID) database includes 728 different policies coded by topic area. We provide an overview of this new dataset and illustrate two key uses: (i) static and dynamic innovativeness measures and (ii) latent diffusion networks that capture common pathways of diffusion between states across policies. The scope of the data allows us to compare patterns in both across policy topic areas. We conclude that these new resources will enable researchers to empirically investigate classes of questions that were difficult or impossible to study previously, but whose roots go back to the origins of the political science policy innovation and diffusion literature.  相似文献

This article examines the intersection between the Cold War and decolonisation in anti-Communist Asia in the 1950s. Drawing on the papers of former South Korean President Syngman Rhee housed at Yonsei University, the article explores both the motivations behind as well as the constraints upon South Korea's efforts to cultivate a military alliance in what it called ‘Free Asia’. Articulating some of the concrete political differences between South Korea and its potential partners in Asia, the article argues that Rhee's hardline views of the Cold War were interwoven with his ambivalence about Japan's reintegration in the post-war world. As a result of this intersection between the Cold War and decolonisation, the South Korean President was unable to achieve consensus with the rest of anti-Communist Asia. In exploring this chapter of South Korean diplomacy, the article calls on Cold War diplomatic history to integrate non-Communist Asia and for the historiography of decolonisation to investigate the legacies of Japan's empire in post-war Asia. It also suggests that scholars ought to reflect more deeply on the interrelationship between the Cold War and decolonisation.  相似文献

Tyranny in the modern era turned toward totalitarianism through the idea that human nature needed to be “perfected”; communism's enemy was a matter of class, Nazism's a matter of race. Democracy would seem by definition to resist such ideologies, but even the modern democratic state now possesses mechanisms that can be turned in tyrannical directions: regulatory powers, social welfare systems, and the new tools of artificial intelligence and “big data.” American democracy has been trending toward the “direct” form of democracy that the Founders recognized in ancient Athens and were determined to avoid, a degree of popular sovereignty capable of producing demands upon government that, in turn, could transform a people's government into a government's people. The best defense may be found in classic American literature's examination of national character and identity.  相似文献

Australia, like most other developed democracies, is often alleged to suffer from ‘casualty phobia’. The perception that the Australian public will not tolerate casualties in foreign conflicts has shaped the decisions of both civilian and military policy makers. Measures taken to protect Australian forces from casualties may, for instance, also serve to increase the risk to civilians in the country to which they are deployed. The USA underwent a similar debate some years ago. Innovative public opinion research techniques—especially ‘survey experiments’ which allow researchers to establish causal relationships by consciously manipulating one variable while holding others constant—have established that the American public are not reflexively casualty-phobic and that the impact of casualties on public opinion can be outweighed by other factors, such as the public's confidence in the mission's overall success. In this article, the author replicates one of the key survey experiments from the US debate, suitably adapted to Australian conditions, with a nationally representative sample of Australian voters. The author finds that the same pattern holds in Australia as in the USA: casualties do lower public support for a given mission, but the mission's chances of success matter more.  相似文献

The Nasca culture of the south coast of Peru developed during the first millennium ad and is known internationally for its elaborately decorated polychrome pots. Despite decades of iconographic analysis, little is known about the more technological aspects of Nasca pigment production and application. We present results from a pilot study on iron isotopes as a potential line of inquiry into the differences between red and black pigments in Nasca pigments. As well, we conduct a small firing experiment to examine potential changes in isotope composition. Our analyses show three significant results. First, firing does not change the isotopic ratios of Fe in pigments. Second, red and black pigments show differences in their iron isotope composition, which relate to differences in the minerals used to make the different colors. Third, naturally available hematite samples show greater isotopic variation than pigment samples, suggesting that people selected a limited range of iron oxides to produce pigments.  相似文献
