This article examines the printed representation, and prosecutorial characterisation, of the movements, actions and motivations of early Quakers as vagrant. It argues that the prevalence and power of representing (and subsequently treating) early Quakers as vagrants is an understudied aspect of the social and cultural history of the Society of Friends, particularly in Interregnum England. As evidence, it interrogates a furious pamphlet debate between mid-century religious writers and preachers, who devoted much time and ink to painting Quakers as mendacious vagabonds, and Quaker ‘First Publishers’, who responded at length and in a striking way to these accusations. The article concludes that these images of Quakerism as a form of ‘spiritual vagrancy’ created historically significant echoes in English and Atlantic culture.  相似文献

鄯善乃西域古国之一,新疆出土的佉卢文书多涉及其国政治、经济、军事、文化和法律等诸多方面的问题,这批文书很好地反映了鄯善王的施政特点:鄯善王通过在全国建立严密的行政管理系统,使用严格细致的法律体系,再加上极力武装的胜兵体制、“专车”专用的交通制度以及事无巨细的统一管理使得鄯善逐渐富裕,成为西域城邦大国之一。  相似文献

Nostalgia and homesickness were well-known eighteenth-century ailments. Undertaking protracted travels, Grand Tourists were potential sufferers, yet these emotional afflictions are absent from the Tour's lengthy lists of hazards. Querying this and applying history of emotions approaches to the histories of the Tour, masculinity and the family, this article examines how Tourists and tutors navigated nostalgia and homesickness as emotions that sat uneasily with the Tour's wider aims of masculine formation. Such investigations offer a means of unpicking the complex, contradictory demands placed on young gentlemen during their emotional formation. Through this, it contributes to wider reconsiderations of eighteenth-century masculinity.  相似文献

This paper responds to a trend of contracting out subjective well-being econometrics to demonstrate social return on investment (SROI) for evidence-based policy-making. We discuss an evolving ecology of ‘external’ research taking place ‘between’ the academy and commercial consultancy. We then contextualise this as waves of research methodologies and consultancy for the cultural sector. The new model of ‘external between’ consultancy research for policy is not only placed between the University and the market, but also facilitates discourse between policy sectors, government, the media and the academy. Specifically, it enables seductive but selective arguments for advocacy that claim authority through academic affiliation, yet are not evaluated for robustness. To critically engage with an emergent form of what Stone calls ‘causal stories’, we replicate a publicly funded externally commissioned SROI model that argues for the value of cultural activities to well-being. We find that the author’s operationalisation of participation and well-being are crucial, yet their representation of the relationship problematic, and their estimates questionable. This case study ‘re-performs’ econometric modelling national-level survey data for the cultural sector to reveal practices that create norms of expertise for policy-making that are not rigorous. We conclude that fluid claims to authority allow experimental econometric models and measures to perform across the cultural economy as if ratified. This new model of advocacy research requires closer academic consideration given the changing research funding structures and recent attention to expertise and the contracting out of public services.  相似文献

This article explores the textual and historical poaching practices by Tumblr fans of the novels A Song of Ice and Fire and the television adaption Game of Thrones, a pseudo-historical fantasy series. Fans critique both the text (novels and TV show) and other fans’ interpretations of the text, as well as parallel real-world history with the world and characters of the series. Tensions arise around the “historical accuracy” of the novels and show, along with the role that dominant narratives and cultural norms play in interpreting a past that never was through the lens of a real-world past. Fantasy and history intersect in layered ways and are used by fans to support a variety of textual points of view. Issues of violence, presentism, colonialism, gender, and “historical truths” are argued in relation to the ahistoricism or historicism of the novels/show.  相似文献

ABSTRACT

This article analyzes different ontological categories and how they relate to the conservation of contemporary art. Faced with the necessity of apprehending the work of art from an ontological point of view, a theoretical approach is made on the concepts that most affect the conservation of contemporary art: quiddity, truth-authenticity, identity, quality, consistency, and interpretation. These are analyzed from an empirical perspective, based on the experience of conservation and restoration. Since conserving and restoring require making decisions that will affect the material and conceptual plane of the works, several possible paradigms that must be introduced into the deontological code of the profession are analyzed. In addition, the study of a new paradigm is provided, that of the death of the work of art. This paradigm can serve as a frame of reference, given the impossibility of bringing the ‘Truth’ of the artwork into the world of the sensitive. This may occur due to different conditioning factors and limitations of a material, technical, or intentional type, which affect issues that were once established as essential to the entity. On the other hand, different types of time that are related to the conservation of contemporary art are studied: biological time, the eternal present of the work, time as a constructor agent, and destructive time as a facilitator of the appearance of ruin or ruin-relic in the work of art.  相似文献

Abstract

The Program for Cooperative Cataloging (PCC) has formal relationships with the Library of Congress (LC), Share-VDE, and Linked Data for Production Phase 2 (LD4P2) for work on Bibliographic Framework (BIBFRAME), and PCC institutions have been very active in the exploration of MARC to BIBFRAME conversion processes. This article will review the involvement of PCC in the development of BIBFRAME and examine the work of LC, Share-VDE, and LD4P2 on MARC to BIBFRAME conversion. It will conclude with a discussion of areas for further exploration by the PCC leading up to the creation of PCC conversion specifications and PCC BIBFRAME data.  相似文献
