Abstract

As a direct consequence of exposure to microgravity, astronauts experience a set of physiological changes which can have serious medical implications when they return to earth. Most immediate and significant are the headward shift of body fluids and the removal of gravitational loading from bone and muscles, which lead to progressive changes in the cardiovascular and musculoskeletal systems. Cardiovascular adaptations result in an increased incidence of orthostatic intolerance (fainting) following flight, decreased cardiac output, and reduced capacity for exercise. Changes in the musculoskeletal system contribute significantly to impaired function experienced in the post-flight period. The underlying factor producing these changes is the absence of gravity, and countermeasures are therefore designed primarily to simulate earthlike movements, stresses, and system interactions. Exercise is one approach that has had wide operational use and acceptance in both the US and Russian space programmes, and it has enabled humans to stay relatively healthy in space for well over a year. Although it remains the most effective countermeasure currently available, significant physiological degradation still occurs. The development of other countermeasures will be necessary for missions of longer duration, for example for human exploration of Mars.  相似文献

The extimacy of space   总被引:1,自引:0,他引:1  
Jacques Lacan coined the neologism ‘extimacy’ (extimité) in order to theorize two interrelated modes of psychical apprehension: first, how our most intimate feelings can be extremely strange and Other to us. Second, how our feelings can be radically externalized on to objects without losing their sincerity and intensity. Attending to the socio-spatial dimensions of extimacy, this paper provides insight into the importance of topology in Lacan's work. In so doing, the paper challenges the enduring doxa in geography that Lacanian theories ultimately devalue the intricacies and liveliness of space. To substantiate this claim, I explore the extimacy of the most popular vehicle accessory in the USA since the 1980s' ‘Baby on Board’ signs: the ‘ribbon magnet’. Specifically, I elaborate the extimate contours of two ribbon magnet slogans, ‘Half Of My Heart Is In Iraq’ and ‘I Support More Troops Than You’. Affirming a recent critique that social and cultural geographers have ‘tamed’ psychoanalysis, that is, shied away from working through psychoanalysis's allegedly unseemly conceptualizations of politics and subjectivity, this paper suggests that we have yet to catch up with some of psychoanalysis's most fundamental and valuable theorizations about space itself.  相似文献

The automatic production of space   总被引:2,自引:0,他引:2  
This paper is concerned with the changing nature of space. More and more of the spaces of everyday life come loaded up with software, lines of code that are installing a new kind of automatically reproduced background and whose nature is only now starting to become clear. This paper is an attempt to map out this background. The paper begins by considering the nature of software. Subsequently, a simple audit is undertaken of where software is chiefly to be found in the spaces of everyday life. The next part of the paper notes the way in which more and more of this software is written to mimic corporeal intelligence, so as to produce a better and more unobtrusive fit with habitation. The paper then sets out three different geographies of software and the way in which they are implicated in the reproduction of everyday life before concluding with a consideration of the degree to which we might consider the rise of software as an epochal event or something much more modest.  相似文献

Bullying is an internationally pervasive problem that impacts significantly on the behaviour, health and wellbeing of children. Drawing on ideas developed in both the abundant psychology literature, and the landmark study by Percy-Smith and Matthews Tyrannical Spaces (2001) Percy-Smith, B. and Matthews, H. 2001. Tyrannical spaces: Young people, bullying and urban neighbourhoods. Local Environment, 6(1): 4963. [Taylor & Francis Online] [Google Scholar], this paper examines the psychosocial dynamics of bullying as they interrelate with various environments. The key groups involved in bullying are considered particularly with respect to their spatial rituals, actions and interactions. In the absence of sustained geographical research in this field, some broad directions for future geographies of bullying are suggested as the basis for future inquiry. Some initial indications are provided as to how these might involve, and connect to, existing disciplinary interests in geographies of exclusion, moral and emotional geographies.  相似文献

ABSTRACT. Because of their failure to distinguish enough between interpretation and creation, scholars of nationhood have tended to neglect the role of creativity in both the genesis and persistence of national communities. Giving creativity its due leads us to question the standard conception of nations, and of the states that recognise them, as secular. This, in turn, suggests that we need to interpret the significance that language has for nationalists in a new way. After showing how, the paper concludes with an argument about what this new interpretation should mean for language politics.  相似文献

四川地区至迟到东汉末年至三国时期就已受到西来佛教思想的影响,并产生了一系列与之有关的遗物。成都从汉末佛教传来之初到南朝末年情况非常特殊,在南朝统治的264年中,它有一半时间不在其控制范围内,从未完全归属过南朝中央。在民族和化传统上成都与甘陇地区的关系比与中原或南朝中央地区更近,因此成都地区与中原及建康地区实际上是三个并立的化区。从东晋至南朝,因北方战乱,佛教在东传过程中的相当一段时间内,成都地区在三个化区中均有着特殊的地位,它的佛教思想及其造像特点兼容了南北的一些特点,同时形成了不同于南北的地方特色。历史背景和化因素的改变在佛教造像上都得到了反映。  相似文献

In practice, the care of historic urban space is dominated by planning professionals whose bias is towards the broad remit of the conservation of the built heritage; it remains the exception for other professions to take an active role in the protection of spatial elements of the historic townscape. Neither do these areas enjoy the same degree of statutory protection as their built counterpart, even though they may have played an equally important role in the evolution of our towns and are an integral part of the urban form. This study is the first stage of the author's on‐going research into the value of historic space within the modern urban environment and the level of protection afforded it by the planning system. The results of this pilot study are used to suggest a professional and statutory framework, based upon inter‐disciplinary co‐operation, from which the full value of townscapes may be safeguarded in the future.  相似文献

This article seeks to understand the production of lesbian space in the TV series The L Word (TLW) (Showtime 2004–2009). To do so, it departs from theories of the lesbian gaze to discuss the visibility of feeling. Specifically, I consider how TLW represents the visibility of feeling as constitutive of lesbian bodies, communities and spaces. In TLW, real spaces (actual locations) fold into virtual ones (on screen) in a deliberate construction of televisual lesbian space. TLW implicitly reflects and is embedded within real-life configurations of lesbian space. I identify four excerpts from the series – ‘gay LA’, ‘the pool’, ‘Olivia cruise’ and ‘High Art’ – that problematise lesbian visibility by foregrounding the relationship between feeling and place. Permission to feel, represented as permission to look, reproduces community as the threshold of lesbian identity. Critical to understanding this production of lesbian space is the way in which TLW associates feeling with social relationships as vividly depicted by ‘the chart’, a representational motif that maps lesbian sexual relations and the intelligibility of lesbian feeling. Finally, I develop my account of lesbian visibility through the example of the facial expression of feeling, at once a demonstration of the visible embodiment of lesbian feeling, and the intelligibility of lesbian space.  相似文献

Techniques for estimating the economic importance of plants represented on archaeological sites have usually assumed that plant samples were random in composition. The effects of crop-processing activities and other factors upon the composition of each sample have frequently been overlooked, or their importance minimized. This article proposes an alternative approach and suggests that the economic value of a prehistoric plant resource can be ascertained by considering its context within crop-processing activities. It is argued that the merits of this technique are that it provides a more accurate means, first, of distinguishing between actual and potential plant resources, and secondly, of evaluating their importance.  相似文献

Belgorod oblast is a highly successful region in Russia. The economic successes in Belgorod stem from the dynamic leadership is provided by Yevgeny Savchenko for the past 24 years. Savchenko supports agroholdings and industrial agriculture, while also adopting policies that foster the growth of small-forms of farming and organic farming. Savchenko’s agrarian policies have led to the so-called Belgorod Miracle. The Belgorod experience shows that despite a decline in gubernatorial power vis-à-vis the federal center, governors have vast powers within their regions. Personality and leadership characteristics are important variables that impact the performance of a region.  相似文献

Economic research has rarely considered the significance of the home and neighbourhood context of where business owners live for their business. Conversely, urban and neighbourhood research has overlooked how housing and neighbourhood shape business and entrepreneurship outcomes. This paper investigates the importance of housing and neighbourhood resources for microbusinesses using a random sample of microbusinesses in Edinburgh (UK) including those that are informal and home-based, and various characteristics of the neighbourhood in which the business owner lives were attached to the survey records. The data capture whether business owners have business premises outside their homes, and have used neighbourhood contacts, housing equity or space in the house for their business. In short, housing and neighbourhood resources are used by a large majority (82%) of microbusinesses. The findings challenge a number of common assumptions on the separation of commercial and residential functions, how neighbourhoods feature in the evolution of businesses, the nested conceptualization of home within a neighbourhood and on the nature of home-based businesses. It is concluded that multi-use (rather than mixed-use) neighbourhood planning would help foster more flexible and dynamic use of neighbourhoods and urban districts, although recognizing that this is a political issue.  相似文献
