Images of brain localization from Brain's inception to the present are analyzed. Textual representations and their accompanying images are shown to coevolve; that is, the technological and conceptual development of the research program of localization is shown to evolve simultaneously with the exploitation of visual resources that support these developments. The semiotics of Peirce, the social semiotics of Kress and van Leeuwen, and the insights of Gestalt psychology provide a critical vocabulary with which to describe and to analyze these visual resources. I conclude that brain images evolve in a manner that reflects the uniformity in measuring instruments and the increase in their precision in the localization of brain functions; at the same time, they draw attention away from a persistent constraint: the brain functions so precisely localized are just those that are not constitutive of our humanity.  相似文献

Experiences following stimulation of the senses have been recorded for millennia, and they could be related to the gross anatomy of the sense organs. Examination of their microanatomy was to await the development of achromatic microscopes in the early nineteenth century. Among the microscopic structures that were isolated and described were specialized sensory cells, called receptors, and they could be related to the stimuli that excited them. Those located in well-defined sense organs (like the eyes, ears, nose, and tongue) were named on the basis of their morphology, whereas the receptors in or beneath the surface of the skin were generally named after those who first described them. Illustrations of early representations of sensory receptors are combined with “perceptual portraits” of the microanatomists who described them.  相似文献

Abstract

The potential for everyday soundscapes to evoke diverse emotions amongst different cultural and acoustic communities is increasingly recognised within the literature. However, few studies have examined how these soundscapes can shift with the onset and progression of specific hearing impairments. This paper explores such shifts, drawing on a series of in-depth narrative interviews conducted in the south west of England with individuals diagnosed with Ménière’s disease; a long-term progressive vestibular disorder characterised by episodes of vertigo, tinnitus, sensorineural hearing loss and, for some people, hyperacusis (high sensitivity to sudden irregular sounds). Located in the subfield of ‘emotional geographies’, the paper discusses how participants were forced to connect with and attune to previously unremarkable aspects of their everyday soundscapes in ways that were both emotionally and socially challenging. Four aspects of participants’ embodied, emotional soundscapes are critically explored: hearing life in ‘2D’; corporeal and environmental ‘sonic intruders’; corporeal sound ‘symbols’; and seeking to regain a semblance of control through soundscape (re)-negotiations. Such insights are important to inform conscious acoustic design efforts that respect the ‘ears and voice’ of people living with varying levels of auditory sensitivity, rather than urban and community planning policies that continue to prioritise vision and transit.  相似文献

This article investigates how presidential policy attention is allocated across policy tools and whether there is a channeling of tool use by policy area. I also examine whether there is evidence of disproportionate information processing within presidential policy attention allocation and whether it is common across presidential policy tools. Presidential messages, hearings on administrations' legislative proposals, amicus briefs, and executive orders are employed to capture presidential policy tools. The allocation of attention via these four instruments is examined from 1957–2007 in the policy areas of defense and foreign affairs, macroeconomics, banking and commerce, civil rights, law and crime, and labor and immigration. I find that there is a canalization of presidential policy attention by instrument, and that the opportunity structure of policy tools shapes attention allocation. Additionally, I find evidence for punctuated equilibrium theory in the allocation of presidential policy attention via these four tools. When presidents do shift their attention to an issue area, they often attack the issue with some coordination of their policy instruments.  相似文献

In the nineteenth century, there was a continuous debate on the structure and function of the brain, focusing on localization of function and on epilepsy. France, Germany, and England played a leading role. This article addresses the question of what happened with respect to the study of epilepsy in the Netherlands in that period. A systematic search of the literature has been performed and papers by Schroeder van der Kolk, Huet, Jelgersma, and Niermeijer are discussed. Also two dissertations were selected for discussion, those of Kroon and Langelaan. It is concluded that from a scientific point of view, only the paper by Schroeder van der Kolk deserved and received international attention.  相似文献

By the mid-1960s, local-level development workers in Ghana were expected to act as the eyes and ears of the state, reporting on ‘the minds of the people’ and explaining their reactions to President Kwame Nkrumah's project of socialist reconstruction. This articles argues that through mass education, social welfare and community development plans, both the late colonial and early independent state sought to make its presence manifest in the everyday lives of its citizens, to bind them to a broader vision for their country, and to present their successes to the outside world. By identifying some of the competing models of social development that were promoted by British, Ghanaian and African-American experts in the aftermath of independence, this article investigates the role of specialist knowledge in the developmentalist authoritarianism which is often presented as a generic legacy of the colonial state in Africa.  相似文献

A number of problems associated with the calculation and use of indices for the minimum number of individuals are discussed. Special attention is directed to two of the methods currently in use based on the counting of paired skeletal elements. These methods are described, their ranges of variation determined, and the results of application of each to the same hypothetical faunal sample are described and compared. It is urged that caution be exercised in the application of any of these methods and that the imposition of standardized methods be delayed until a more adequate understanding of the behaviour of even the currently existing measures is available.  相似文献

Transport infrastructure is considered one of the main policy instruments to achieve the cohesion goal, although the inclusion of cohesion effects in assessment methodologies is scarce and uneven. Although most cohesion studies are constrained to the analysis of regional disparities in economic indicators, this approach can be broadened to include other regional performance indicators. One of these indicators could be accessibility measures, from the point of view that accessibility, representing a competitive advantage of locations, constitutes a “desirable good” closely related to the welfare of each region. This paper suggests using changes in the spatial distribution of accessibility as a proxy to assess regional cohesion effects of transport infrastructure investments. However, as the conclusions taken depend heavily on the formulation of the accessibility measure, we recommend computing a set of accessibility indicators and analysing their results in a complementary way. The proposed methodology is tested by assessing regional cohesion effects of the large-scale road and rail transport infrastructure investments carried out in Spain in the period 1992–2004. The results obtained show that cohesion has improved for the road mode, while regional disparities have increased for the rail mode. This paper identifies the main factors driving this final cohesion effect and explores the strengths and weaknesses of the different accessibility indicators that were considered. The approach suggested in this paper has the potential to be applied in transport planning processes, and may eventually complement existing strategic assessment methodologies.  相似文献

Philosophical instruments were designed to examine phenomena experimentally, rather than by naturalistic observation alone. In the nineteenth century, some instruments were called philosophical toys because they provided popular amusement as well as experimental assistance. They were applied widely in natural philosophy, but attention here is directed particularly to manipulations of perceived space and time and their influence on art. One of the earliest instruments, which had a profound impact on art as well as science, was the camera obscura. It assisted image formation in art before it was applied as an analogy to the eye at the beginning of the seventeenth century. Later philosophical toys were used to address visual perception of motion and depth. Development was initially driven by the need for stimulus control so that the methods of physics could be applied to the study of perceptual phenomena. The principal instruments were invented in the first half of the nineteenth century, and they consisted of simple contrivances that manipulated time and space in ways that had not previously been appreciated. They included thaumatropes, phenakistoscopes, stroboscopes, anorthoscopes, stereoscopes, tachistoscopes, and chronoscopes. Several of these philosophical toys proved to be phenomenally popular, particularly when combined with photography.  相似文献

The current pattern of spatial disparities in Europe increasingly reflects the different networking capacity and competitive orientation of European localities. The article focuses on the north-south pattern of disparities and discusses the particularities of the economic and socio-political contexts of urbanization and local governance in the southern states of Spain, Greece and Portugal. The European Union (EU) networking initiatives, it is argued, have limited provisions in their structures for the north-south divergence of European local governance, endangering an increase in disparities. The responses of seven northern and southern local authorities to two EU RECITE networks (1992-1997) are comparatively examined in this framework.  相似文献

The act of scalping has long been associated with Native American conflict‐related human body part trophy taking. Reasons for their removal were varied and often included communal and personal factors. Previous research has identified several different types of scalp removals based on the amount of soft tissue affected during the process of scalping. One of these types can involve the removal of the ears. Through reanalysis of known scalping victims within the middle Tennessee Valley of North Alabama, we have identified five cases where victims were both scalped and had their ears removed. These cases provide a unique understanding of the practice of human body part trophy taking. They support ethnographic accounts that indicate ear removal has great time depth and was geographically widespread. Although the five cases presented here are similar to total compound scalpings, they actually represent total simple scalpings. Unlike total compound scalpings, where the ears are removed attached to the skin of the scalp, these cases show evidence of secondary removal of the ears after the scalp was already detached. This secondary removal of the ears after the act of scalping supports the interpretation that the aggressors intended different purposes for each trophy. It is likely that the scalp and ears each had their own meaning. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

Our paper draws on research in two sites where large goldmining projects are located — Misima and Lihir islands in Papua New Guinea. We examine the socio‐economic context in which criticisms of environmental degradation arise. We discuss the social and political meanings embedded in local demands for compensation for environmental damage, drawing attention to the disparities between local Melanesian conceptions of the environment and global, Western ideas that inform international environmentalist criticisms of mining. We dispute the ‘romantic primitivism’ of some environmentalist discourse, using the work of ethno‐ecologists and case studies of specific incidents on these islands, contesting the view that there is a natural conservationist ethic in Melanesia. The image of the ‘noble primitive ecologist’ that some environmentalists appeal to, would in most circumstances be rejected by Melanesians as racist and paternalistic, but is embraced as a strategy in conflicts with mining companies and when making legal claims for compensation. Alliances formed between landowners, environmentalists and western lawyers against mining companies such as BHP and Rio Tinto are based more on shared political ends than on the epistemological consistency of their perceptions of environmental damage from mining. Local Melanesian communities claim sovereignty over all resources and their compensation claims for environmental degradation constitute a new form of resource rent.  相似文献

A total of forty-nine stringed instruments of the Conservatory Cherubini collection, at the Musical Instruments Department of the Accademia Gallery in Florence, were submitted to a dendrochronological investigation in order to date them, check the validity of their attribution and to find out more about their construction characteristics. Thirty-seven instruments were successfully dated, thereby determining the terminus post quem date of manufacture. The correlation values of the statistical cross-dating tests were generally very high. The dendrochronological analyses determined which instruments had been made from wood of the same provenance and, in some cases, from the same tree trunk. The mean chronology built from the musical instrument series, named “Accademia Master Chronology”, is 558 years long and dates from 1396 to 1953AD. The interval between the youngest ring dated dendrochronologically and the given date of manufacture increased constantly in the course of the centuries, from a mean value of just over eleven years for instruments built in the eighteenth century, to nearly 74 years in the twentieth century, when the use of old wood from other artefacts became more frequent. Furthermore, in the Cherubini Collection, the average tree rings on violins are smaller than those of other stringed instruments; in fact, they increase in proportion to instrument size and are widest in cello and double bass.  相似文献

The influence of environmental policy on innovative behaviour of companies has so far received little attention in scientific discourse. Based on recent literature, the paper analyzes the impact of requirements, levies, permits, liability laws, and the EC‐eco‐audit regulation with respect to the generation of environmentally benign innovations. Most theoretical studies come to the conclusion that direct requirements provide little incentives for dynamic effects and that emission taxes and permits are better instruments to promote innovations. However, the empirical studies show that the dynamic effects of environmental policy instruments in practice partly differ from the ideal instruments analyzed in theoretical studies.  相似文献

ABSTRACT

The development of non-core regions has attracted growing interest within the current debates of economic geography, regional studies and spatial planning. The divergence between economically successful core regions and less privileged non-core regions continues despite policy interventions aimed at tackling spatial disparities and income inequalities. While traditional growth-oriented policies raise concerns over their effectiveness and relevance beyond large cities and metropolitan regions, there is growing interest in exploring new research paths and policy options that are better able to address development challenges in non-core regions. Contributors to this special issue engage with these debates by reflecting on planning policies and practices in five European countries, paying special attention to identifying planning strategies for non-core regions. This paper argues that alternatives to growth-oriented models require additional conceptualization and analysis to translate values into policies and institutions.  相似文献
