As part of emerging disciplinary interests in well‐being and emotions, geographers have recently begun to pay attention to common but often neglected psychological conditions that have the potential to impact considerably upon individuals and their daily lives. Specifically extending the scope of geographical inquiry on phobias, this paper considers acrophobia (known as being scared of heights). Through interviews with ten sufferers, the spatial character and intensity of the condition is articulated. The findings tell us that underpinning acrophobia is mathematical height: the vertical elevation from the lowest possible resting point of the body to the point at which the symptoms of acrophobia occur. This point is however ‐ even for each individual ‐ highly variable, context dependant and, in terms of explanatory potential, does not convey personal experiences. Instead, the idea of ‘encounter spaces’ provides far greater elaboration. Created by sufferers ‘dysfunctional’ spatial perceptions, these are the occupied spaces of mixed emotional and physical responses (such as fear and rapid breathing) and reactionary practices that are tactical yet somewhat involuntary in nature (such as gripping tighter or getting lower). Depending on the particular circumstances, sufferers might choose to, feel forced to, or might inadvertently enter encounter spaces. Their impacts also extend beyond immediate effects to sufferers’ longer term lives and well‐being. This might be negatively impacted, for example, through cumulative encounters, worrying about potential encounters or missing out on life events. At this level, reactionary practices ‐ again which are tactical yet somewhat involuntary ‐ are often employed in order to avoid height. Ultimately, the overall impact of acrophobia on an individual depends on a number of factors including the severity of their condition, the attitudes of the people they associate with, their job, lifestyle and the environments which they have to, or would like to, frequent. Consequently, while some sufferers cope with ease, others constantly navigate the altitude of their lives. 相似文献

The parliamentary organisation of the whig Junto in the reign of Queen Anne was far superior to that of the tory party. At the centre were the meetings in which three or four of the five members of the Junto were present together with some of their followers. Evidence of such meetings is rare but here is presented a letter giving the details of a meeting of all five in April 1713 at the home of Lord Somers, together with their ally, the tory earl of Nottingham, probably to discuss the forthcoming peace proposals, to end the war of the Spanish Succession, and the protestant succession to the British throne. 相似文献

This article examines the political history of the parliamentary borough of Ripon between the Great Reform Act of 1832 and the Second Reform Act of 1867. It challenges the notion that Ripon remained a ‘pocket borough’ during this era; rather, the Reform Act rendered Ripon's politics much more open, vibrant and participatory than they had been during the ‘unreformed’ era. In demonstrating this, the article calls into question the alleged prevalence of ‘pocket boroughs’ in the reformed era. 相似文献

In Zambia, the ways in which social change intersects with rural livelihoods to increase children’s workload and commodify their labour are poorly understood. In this article, changing patterns of rural children’s work are seen as necessitated by their evolving household roles and contributions in an increasingly rural cash-based economy. Drawing on child-focused qualitative research in rural Lundazi district in Zambia, it is explored how children use a traditional labour practice called ‘ganyu’ (piecework) to ameliorate poverty. The infiltration of the cash-based economy, amplified by the Economic Structural Adjustment Programmes, a predominantly adult-centred traditional informal socio-economic levelling mechanism of ganyu, and its evolution into more cash-oriented transactions increasingly involving children are discussed. Although ganyu has largely been seen as characterized by exploitative labour relations, the empirical findings from this research indicate the complex ways in which the practice is empowering children and their families. The resources accrued through ganyu are vital for both personal and household well-being. The findings of this study have important implications to rethink not only contentious issues of child labour but also dominant narratives of childhood that fail to take into account children’s lived experiences as situated in local, social, economic, and cultural contexts. 相似文献

This Keynote essay argues for a supplement to existing studies in children’s geographies, one that explores the potential of a non-child-centric children’s geography alert to the work done by the figure of ‘the child’ in all manner of worldly situations. Taking a cue from the poetry of John Betjeman, notably his 1960 Summoned by Bells, the essay considers both the intimate spaces of childhood – ones gauged by the immediacies of ‘sounds and sights and smells’ – and the challenges posed by a wider world raddled by adult preoccupations and abuses, those characterised by Betjeman as stemming from ‘the dark of reason’. The essay builds from this foundation to address the ‘darkness’ in two sets of Nazi children’s wartime geographies, as well as engaging with the complexities of Theodor Adorno and Max Horkheimer’s claims, in the horizon of WWII, about the ‘dialectic of enlightenment’. Within the latter – and also, notably, in Adorno’s later writing – the figure of ‘the child’ surfaces as one miniscule crumb of hope, of experiencing and knowing the world otherwise, set against the face of adult Enlightenment’s seemingly inevitable decay. At the close, Adorno’s own brief dalliance with imagining a small slice of children’s geographies allows the essay to arc back towards its original claims, and to a renewed sense of why childhood ‘sounds and sights and smells’ continue to matter far beyond just the domain of geographers researching children. 相似文献

The Basilica of San Francesco in Assisi endured stronger earthquakes for centuries before 1997 earthquake, which generated the collapse of the two vaults. Experts blame as possible reasons of collapse the damage cumulated from previous earthquakes and/or the retrofitting made to the structure over its lifetime. This article presents the history of the retrofit interventions of the Basilica through the centuries, focusing mainly on the roof, which has been subjected to three major restorations through its life. It is shown using simple analytical models that the cumulative effects of the changes made to the roof of the Basilica affected the structure’s dynamic behavior in a negative manner, increasing the seismic loads on the existing structural members. In particular, the numerical results show that the 1958 roof intervention has stiffened the structure, redistributing the seismic loads on the façade and the transept. This overload might explain the collapse of the two Gothic vaults during 1997 earthquake. 相似文献

A framework for quick seismic assessment and retrofit of traditional unreinforced masonry (URM) structures is presented. The proposed methods build on simple principles of structural dynamics and are used as an alternative to detailed time-history analysis, in recognition of the prevailing need for simple and practical methods, compatible with the low-budget and the limited level of knowledge regarding materials, internal force paths, connectivity and condition of older URM structures. An objective is to identify areas in the building that are particularly susceptible to damage and for guiding the types of the required global interventions to improve seismic response. Demand and supply are expressed in terms of relative drift ratios that quantify the intensity of out-of-plane differential translation and in-plane shear distortion of masonry walls. A characteristic traditional building type of timber-laced masonry is used as a model structure for illustration of concepts. The morphology and geometry of the building correspond to a statistical sample of the actual traditional unreinforced masonry buildings (TURM) found in historical centers of many towns in the greater region of Northern Greece. The methodology is particularly useful for setting retrofit priorities and management of the collective seismic risk of historical entities. 相似文献

The ‘Troubles’ is a euphemism associated with sectarian conflict in Northern Ireland from the late 1960s until the late 1990s. Similarly, that term also is used to depict turmoil in all of Ireland between 1916 through 1924. During both eras, political imprisonment coupled with various forms of political violence (e.g. bombings, executions, and prisoner abuse) marred Irish society in ways that invoke socio-religious meaning. In particular, the sanctity of death captures the intense semiotics of those events and points to further theorising along lines of the Durkheimian tradition. As we shall examine herein, violations of the sanctity of death compound social conflict and the resistance it creates. Fieldwork was undertaken in Dublin and Belfast where official landmarks were explored in-depth: Kilmainham Gaol and the Crumlin Road Prison, respectively. Additionally in Belfast, other – unofficial – cultural sites provide further evidence of socio-religious symbolism, most notably the Irish Republican History Museum, Roddy McCorley’s Club in West Belfast, and murals in both Loyalist and Republican communities. Whereas Durkeimian theory remains at the forefront of the analysis, insights also are informed by heritage studies, in particular notions of cultural performance in contested societies. 相似文献
