THE ARCHAEOLOGY OF COMMUNICATIONS’ DIGITAL AGE

Abstract

This paper reviews the history of the digital age of communications that began with the invention of the stored program computer in 1948 and is today realised by the World Wide Web, super fast broadband and the smart phone. Taking a predominantly UK focus, the paper examines the key technological advances that were made, where they occurred and what archaeological evidence remains of their existence. The paper begins by examining how digital technology was applied to the telephone network, how that network then provided the means by which early computers could be connected together, and from there to subsequently offer access to information services. Packet switching, the home computer, modems, optical fibre and the Internet are reviewed in terms of their importance in the creation of and growth in the World Wide Web. Finally, the application of digital technology to the mobile phone is discussed in terms of the development of mobile networks and the evolution of the handset into today’s smart phones. The paper concludes by recognising that much of the archaeological evidence of communication’s digital age has already been lost and that urgent action is needed to put in place appropriate preservation strategies.     

Enacting nationalism through youthful mobilities? Youth,mobile phones and digital capitalism in a Lao‐Vietnamese borderland

Mobile phone use has become a defining feature of what it means to be young, and the relatively remote Lao‐Vietnamese borderland area that is the focus of this study is no exception. Drawing on Benedict Anderson's Imagined Communities, this article investigates the interplay between the everyday styles of being young, the forces of digital capitalism and the enactment of nationalism. We do this with a focus on ethnic minority youth's appropriation of the mobile services offered by Viettel, the most popular mobile services provider in the study area and owned by the Vietnamese Ministry of Defence. We suggest that the everyday performances of being young, revolving around the mobile phone, are affected by the forces of digital capitalism. We further suggest that the cultural context of Viettel's digital capitalism is embedded in a fabric of Vietnamese nationalism, leading ethnic minority youth, consciously and unconsciously, to enact nationalism through their everyday styles of being young.     

New Philadelphia: using augmented reality to interpret slavery and reconstruction era historical sites

Does a historical site lose its significance or become less worthy of interpretation if there are no surviving buildings? Can technology help present the stories of disadvantaged and disenfranchised groups whose heritage lacks well-preserved architecture or material culture? The emerging technology of augmented reality (AR) offers new ways of designing and shaping the public’s experience when visiting landmarks by enabling an unprecedented means to combine 3D historical visualization with historical landmarks. This especially applies to underrepresented groups whose heritages have not been well served by traditional modes of preservation and interpretation due to a variety of factors. These range from disadvantages relating to material culture to a greater emphasis on intangible heritage which have placed them outside the bounds of what archaeologist Laurajane Smith calls authorised heritage discourse. A project at the New Philadelphia National Historic Landmark, located in Pike County Illinois, seeks to address these issues through AR. The technology, while offering opportunities for historical interpretation, poses challenges in terms of designing AR systems that coordinate content presentation with specific locations as well as developing virtual historical content with varying levels of source materials.     

Civil War heritage as American diplomacy, 1957–1965

This paper explores the role of Civil War heritage in U.S. public diplomacy during the Cold War era. Especially during the celebration of the Civil War’s centennial, between 1961 and 1965, the Americans endeavoured to harness the conflict’s heritage to promote U.S. interests in Europe. How they intended to do this is demonstrated primarily through an examination of Colonel Sidney Morgan’s mission to Europe to find how the commemoration of the Civil War could be used for public diplomacy. Additionally, by exploring how Civil War heritage was spread and used in the British public sphere, the paper examines and underlines the key role saved to unofficial cultural agents, such as Civil War re-enactment clubs and private people, in heritage diplomacy. The focus on unofficial agents and networks enable this study to show how heritage diplomacy works at the un-institutionalised level and to explore the interaction between the official and unofficial level in heritage diplomacy. The historical perspective and methodology cast new light on the use of history, historical memory and heritage for diplomatic ends and introduces both historians and heritage scholars with new avenues to explore, such as the role of memory and historical consciousness in shaping international relations.     

The Impact of Mobile Technology on Low‐Income Communities in Lebanon

This article attempts to study the impact of mobile technology, as represented by mobile phones, on low income communities, as represented by farmers in the Bekaa Valley, the largest farmland of Lebanon. It aims to identify areas where the mobile phone has a positive impact on farmers' lives, family, friends, work, finance, and health; and areas where the mobile phone has a negative impact on farmers' lives, in addition to identifying some important associations among the variables. The results show that more than 38 percent of farmers own a mobile phone. The benefits of having a mobile phone are improved work, better income, improved family and social ties, more freedom and independence, better health, and better finance. High cost and accessibility were the two major drawbacks. Owning a mobile phone is associated with education, better work, better income, better health, and better finance. It is independent of gender and income. The study recommends that telecommunication companies in the area should expand their services to low‐income communities, improve coverage, and reduce cost.     

Duty to God/my Dharma/Allah/Waheguru: diverse youthful religiosities and the politics and performance of informal worship

This paper draws on a case study of the Scout Movement in the UK to explore the everyday, informal expressions of ‘worship’ by young people that occur outside of ‘designated’ religious spaces and the politics of these performances over time. In analysing the explicit geographies of how young people in UK scouting perform their ‘duty to God’ (or Dharma and so forth), it is argued that a more expanded concept of everyday and embodied worship is needed. This paper also attends to recent calls for more critical historical geographies of religion, drawing on archival data to examine the organisation's relationship with religion over time and in doing so contributes new insights into the production of youthful religiosities and re-thinking their designated domains.     

Student geographies and homemaking: personal belonging(s) and identities

Studies of the ‘geographies of students’ have become increasingly prevalent across the social sciences and are particularly concerned with the predilection for young UK University undergraduates to be mobile in their institutional choice. A more recent focus within this work has been upon student identities, with attention given to how the spaces to which students move and in which they settle can have both positive and negative consequences for the evolution of the student identity, and how such identities are often framed within the context of social activities; learning environments; friendship networks; or other sociocultural factors. This paper contributes to these discussions by considering the role of student accommodation – a site which often remains on the periphery of discussions of student identities – in offering students opportunities to construct, adapt and manage their student identities. This adds to the important contemporary geographies of student accommodation, which are currently debating, among others, purpose-built student accommodation and the broad housing ‘careers’ and strategies of students. In contrast, this paper explores the micro-geographies of student accommodation (and more specifically, the bedroom) to highlight its value in providing young, mobile students with an anchor within which they can draw together their learner, social and domestic dispositions into one geographical location.     

Heritage as sector,factor and vector: conceptualizing the shifting relationship between heritage management and spatial planning

Heritage is a highly malleable concept that is constantly in flux and whose substance and meaning are continuously being redefined by society. From such a dynamic perspective, it is inevitable that new approaches and practices have developed for dealing with heritage in the context of planned development. While most scholars acknowledge the existence of various heritage approaches, one of the major defining features is often neglected: their distinctive outlook on spatial dynamics. In this article, the shifting role and purpose of heritage conservation in Dutch spatial planning is analysed. A conceptual framework is introduced that frames three approaches to the planning treatment of heritage; the sector, factor and vector approach, respectively. Although these approaches have developed in a historical sequence, the new did not replace the old but rather gained ground amongst different actors. Thus, three quite different ways of treating the past in the present now coexist in Dutch planning practice. Although this coexistence can raise conflict, we argue that contemporary heritage planning does not call for a one-size-fits-all approach, but rather for a mixed-mode model.     

Ethical consumption? There's an app for that. Digital technologies and everyday consumption practices

Ethical consumption mobile phone apps are increasingly popular. These apps allow consumers to scan the barcodes of products they are considering purchasing and determine whether or not they align with their ethics. App technologies are often applauded for their potential to provide consumers with targeted, crowd-sourced information about products while shopping and to foster more political, and less individualistic, consumption practices by connecting users to one another and to campaigns. There is a growing field of scholarship conceptually examining the role of information and digital technologies in ethical consumption. However, there is little empirical research on how consumers engage with ethical consumption apps in everyday ways. Drawing on an in-depth study with 21 participants, this paper explores how app use mediates people's experiences of ethical consumption. We contend that the app design structures and limits how individuals engage in ethically motivated consumption and influences their conceptualizations of ethical consumption as a political practice. We conclude by illustrating that critically examining what it means to be “ethical” in a digital world is a crucial area of research for geographers, particularly as these ethics play out through the everyday use of mobile technologies.     

Action heritage: research,communities, social justice

Societies are unequal and unjust to varying degrees and heritage practitioners unavoidably work with, perpetuate and have the potential to change these inequalities. This article proposes a new framework for undertaking heritage research that can be applied widely and purposefully to achieve social justice, and which we refer to as action heritage. Our primary sources are semi-structured conversations we held with some of the participants in three heritage projects in South Yorkshire, UK: members of a hostel for homeless young people, a primary school, and a local history group. We examine ‘disruptions’ in the projects to understand the repositioning of the participants as researchers. The disruptions include introducing a scrapbook for personal stories in the homeless youth project and giving the school children opportunities to excavate alongside professional archaeologists. These disruptions reveal material and social inequalities through perceptible changes in how the projects were oriented and how the participants thought about the research. We draw on this empirical research and theorisations of social justice to develop a new framework for undertaking co-produced research. Action heritage is ‘undisciplinary’ research that privileges process over outcomes, and which achieves parity of participation between academic and community-based researchers through sustained recognition and redistribution.

Universal Access for Universal Value: Creating Disabled Access at Heritage Sites for those with Mobility Impairments

Abstract

In today's society it is recognized that all people, regardless of disability, should be welcomed at heritage sites. As mobility impairments are one of the most common types of disability faced by visitors to heritage sites, this study will look at how the changing views on disability discrimination have affected heritage sites by reviewing current legislation and comparing it with visits to heritage sites in the UK and the US. For this purpose, site visits looking at adaptations for mobility impairments were carried out at fifteen sites in the UK and six sites in the US. There are additionally three case studies: a comparison between a UK and a US early nineteenth-century naval vessel, a site with traditional adaptation methods, and one that has creatively designed access. Overall, both the UK and the US have adopted similar methods for creating disabled access. Yet, the research shows that although many sites have designed some type of access, there is no conformity as to how this access is achieved. In addition, many sites use the loopholes in legislation to ensure that little is changed in the physical material. In the end, it is evident that more must be done to find a compromise between accessibility and preservation.     

Aspects of Archaeological Heritage in the Cultural Landscapes of Western Anatolia

Throughout the course of time, environments built within landscapes have been transformed into conserved archaeological heritage sites through natural, but mostly anthropogenic, forces. Today, cultural heritage is the product of visual and spatial features of architectural material and landscapes created through conservation, but also through social and economical needs and interests. In Western Anatolia, archaeological heritage sites with ecologically rich areas, countryside, coastlines and seascapes are the most essential visual, spatial and structural features of cultural (historical) landscapes. Moreover, western Anatolian landscapes have retained their authentic character regarding intangible cultural diversity, ecology, rural traditional systems and agricultural practices. However, rapid changes and developments due to urbanisation and mass tourism have made their impacts on cultural historical landscapes in recent years. In this paper, an attempt is made to explore the cultural heritage within the evolution of cultural archaeological landscapes in Western Anatolia and to propose a sustainable approach for development and conservation options for cultural heritage and their landscapes.     

“茶马古道”遗产保护中的文化品牌建设

文化遗产可以展现一个地区的文化脉络,也是评价该地区文化深度与厚度的要素之一。对待历史功能在现代社会发生了一些转变的文化遗产,应该加以保护还是改善开发是学界引发广泛讨论的论题。而冻结与封存并不能体现文化遗产的价值,尽管茶马古道的部分历史功能已经消逝或改变,但其在过去近20年问已经以一个文化标签的形式进入了大众文化视域,成为一个区域形象符号。树立品牌建设观念,遵循文化品牌建设的原则、规律进行综合性的保护与利用,是此类跨区域、跨民族、跨文化类型的文化遗产保护与传承的重要方式。     

基于手机信令数据的大型足球赛事球迷当日空间行为特征研究

利用手机信令数据,以2014年3月上海申花与杭州绿城、上海上港对上海申鑫两场足球赛为研究对象,分析和归纳了观赛球迷的分布特征、活动特征,并进一步探索了球迷的行为对于球场周边商业体的影响,以此来分析大型赛事球迷的空间行为特征,希望能够对未来的城市相关设施规划起到一定的指导作用。研究表明,球迷的分布涵盖市域、呈现类圈层结构。球迷的出发时间与球赛开始时间相关,大部分球迷的出行目的较为明确。球迷对于球场周边一定距离范围内的商业体有影响,且商业体距离球场越远,影响越弱。最后,对于手机信令数据在大型活动或特定人群特征分析方面的应用提出了一些讨论思考。     

Community-based Heritage Management: a case study and agenda for research

Heritage sites regarded as important are safely managed by the state, voluntary or private sectors but the majority of sites, despite statutory protection, remain unrecognised and without a role in their host communities. New schemes such as the Local Heritage Initiative in the UK aim to encourage communities to recognise their heritage assets and in managing them effectively to contribute to their preservation. With reference to the case of Nether Poppleton near York (UK), the present study explores the factors and conditions for effective community management displayed in one locality by groups who are successfully conserving and managing a diverse set of local heritage sites. Interviews and joint tasks enabled an analysis of the complex range of factors and conditions that can lead to a successful community-based initiative. Future research will determine the extent to which these factors, if applied to other sites, might produce the same results. The importance of this agenda is underscored by the increasing reliance on community-based heritage management in the UK and elsewhere.

Absence/presence and the ontological politics of heritage: the case of Barrack 57

19 July 2009. A barn burns down in a small Dutch town. Afterwards, this invisible and insignificant ‘barn’ became widely known as ‘Barrack 57’. The destruction triggered attention and led to the barn’s association with a Nazi Second World War transit camp and with Anne Frank. Its material destruction made this barn/barrack both present and absent in various networks. We use the case of Barrack 57 to study the interplay between presence/absence and non-existence of objects in these networks, an exercise which connects to and contributes to the development of constructivist perspectives on object formation in heritage studies. Our analysis of presence/absence and non-existence therefore is based on different concepts developed in actor network theory and Niklas Luhmann’s theory of social systems. Of particular importance is Luhmann’s distinction between first- and second-order observation. We argue that heritage objects themselves are the result of different enactments of (non) human properties in various relational configurations. With this view, a new task for critical heritage scholars emerges. Understanding the dynamics of presence/absence and non-existence of heritage objects in different networks deepens insight into the broader issues of the formation of heritage objects and their delineating technologies and the policies of normalisation and naturalisation.     

Reconsidering Relocated Buildings: ICOMOS,Authenticity and Mass Relocation 1

ICOMOS charters guide global heritage conservation practices. Fundamental to most is the notion that a ‘monument is inseparable from the history to which it bears witness and from the setting in which it occurs.’ Yet buildings have been moved for centuries. Neither the fabric nor the size of a building, nor planning regulations, nor even heritage listing, have prevented their relocation. This article briefly examines the history of relocation, reviews attitudes to relocation in ICOMOS charters, and analyses two case studies involving the mass relocation of heritage buildings in the UK and in New Zealand to question the assumption that buildings lose their authenticity if moved.
