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.     

The Ethics Minefield: Issues of responsibility in learning and research

Google Glass was deployed in an Urban Studies field course to gather videographic data for team-based student research projects. We evaluate the potential for wearable computing technology such as Glass, in combination with other mobile computing devices, to enhance reflexive research skills, and videography in particular, during field research. The utility as well as the limitations of Google Glass are discussed, including its actual and potential application for teaching and data gathering purposes in the field. As such, this article constitutes one of the first instances of evaluating Google Glass as a social science research tool.     

Editorial: Geography and the ‘European Year of Citizenship through Education’

The paper introduces a library of video podcasts (vodcasts) used to support the learning and teaching of geographical methods and techniques relating to physical geography and GIScience in particular. While the notion of video learning is not new, the accessibility of the multimedia snippets via lightweight mp4 players in a field context allows a geographical freedom to learning that goes beyond previous classroom-based work. Evaluation, conducted through the use of reflective diaries and focus groups, identified that all students thought the podcast reference library was a valuable learning resource, of particular appeal to students with a visual approach to learning.     

Simulating archaeologists? Using agent-based modelling to improve battlefield excavations

The study of material culture generated by military engagements has created an emergent sub-discipline of archaeological studies centred on battlefields. This approach has developed a particular and sophisticated methodology that is able to deal with the fact that archaeologists will often not find either structures or a useful stratigraphical record on the site, as the material remains of the battle will basically be metallic objects carried by combatants. It is therefore rather complicated not only to test hypotheses about battle events based on archaeological data, but also to validate the methodology used. Here we propose the use of agent-based models to explore these issues in the case of eighteenth-century battlefield archaeology. The simulation is divided into four different steps. Firstly, a battle is simulated in order to generate realistic virtual archaeological remains left by an engagement between two armies of this era. We then simulate the loss of information that the passing of time produces in the battlefield. The third step involves simulating the archaeological survey, enabling us to explore different survey strategies and the impact on the interpretation of the event itself. Finally, we design a confidence index in order to compare the results of the different virtual excavations using spatial analysis and statistics. The results show that the methodology is fully functional in terms of understanding a battle, and it allows us to suggest new strategies to improve fieldwork and to develop new ways of exploring these particular archaeological sites. It is concluded that the described approach illustrates how simulation can be used to explore methodological issues of archaeological science.

‘PastPort’: Reflections on the Design of a Mobile App for Citizen Heritage in Port Melbourne

This article reports the authors’ design and evaluation of a web-based app called PastPort for the locality of Port Melbourne. Created through an interdisciplinary collaboration between architectural history, planning, cultural heritage and human–computer interaction, PastPort allows local citizens and history groups to post and share historic materials, and is designed to be used by residents and visitors in situ as a mobile guide. We reflect on our design of PastPort, together with evidence from a study of early users, to explore how digital heritage tools quickly become inscribed with historiographic tendencies for how the past might be constructed, communicated and experienced.     

From abstract digital models to rich virtual environments: landscape contexts in Kilmartin Glen,Scotland

This study uses geographic information systems (GIS) based analyses and virtual reality (VR) reconstructions, to explore landscape context for two types of Neolithic monuments: cup and ring rock art and a stone circle. Specifically, the impacts of the contemporary vegetation at the study sites are analysed with regard to viewshed areas and views from the monument locations. Results show that while GIS-based viewshed analysis is useful for quantifying the absolute upper and lower limits for viewshed area, the virtual reality reconstructions allow the possibilities in between these extremes to be explored. In addition, VR provides the opportunity to explore visually rich representations of past environments for site interpretation and it is also a useful way for presenting uncertainty and testing different scenarios for landscape archaeology context.     

Students as Tour Guides: Innovation in Fieldwork Assessment

This paper introduces and details an innovative mode of fieldcourse assessment in which students take on the role of tour guides to offer their lecturer and peers a themed, theoretically informed journey through the urban landscape of Havana, Cuba. Informed by notions of student-centred learning and mobile methods, the tour offers an enjoyable, challenging, rigorous yet flexible form of assessment that can be effectively transferred to a wide range of contexts. Feedback suggests that students are very positive about the tours in relation to other potential modes of assessment both in terms of what they learn and as an experience. Ongoing efforts to develop the tours since they were first used in 2003 are described.     

Ödemiş-Dereuzunyer: Architectural Features of a Rural Settlement to Be Submerged by Dam Waters

ABSTRACT

The village of Dereuzunyer located in the Rahmanlar Valley of the Küçük Menderes Basin is a settlement that is a natural extension of a topography shaped by a joint contribution of culture and nature. It has preserved the authenticity and integrity of its traditional rural fabric and gives detailed information about the architectural approach, building technology, construction techniques, landscape features and traditional craftsmanship of past rural life. While some of the cultural assets in the settlement containing detailed information about the rural lifestyle of the past have survived to date despite the harsh natural conditions, the remainder have been neglected, become dilapidated, and fallen into ruin over time due to lack of maintenance by the local people because of rumors about the possible dam project and expropriations in progress. After completion of the Rahmanlar Dam in 2019, the cultural landscape values of Dereuzunyer will be lost irretrievably. This article aims to make a contribution to creating awareness about avoiding such losses, not only by introducing the non-renewable values of Dereuzunyer, by documentation of its historical development, its traditional architecture, its traditional building types, its construction techniques, and its plan and façade features, but also by promoting and interpreting its lost cultural heritage.     

Enhancing field research methods with mobile survey technology

This paper assesses the experience of undergraduate students using mobile devices and a commercial application, iSurvey, to conduct a neighborhood survey. Mobile devices offer benefits for enhancing student learning and engagement. This field exercise created the opportunity for classroom discussions on the practicalities of urban research, the survey data was available for immediate analysis, and students felt they were conducting meaningful research. The module experience supports recent research finding that mobile devices offer significant benefits for instructors, but using mobile devices also creates potential risks (to the students, equipment, and data) that must be considered while planning modules and during instruction.

THE VIRTUALIZATION OF URBAN YOUNG PEOPLE'S MOBILITY PRACTICES: A TIME‐GEOGRAPHIC TYPOLOGY

A time‐geographic approach, including time–space diaries and in‐depth interviews, is used to investigate the daily use and implications of information and communication technologies (ICTs) among a group of Swedish urban youth. We identify individual variations and nuances in ICT‐based practices in our respondents' social and spatial contexts. Using individual cases and detailed time‐geographic trajectories, we demonstrate how daily communicative actions – physical and virtual – are combined and integrated. From this we identify four ideal types of mobility practices: (i) home‐oriented, heavy Internet users; (ii) physically mobile, heavy mobile phone users; (iii) physically mobile, heavy Internet and mobile phone users; and (iv) home‐oriented, rarely mobile people (virtually and physically).

Untangling Palimpsest Landscapes in Conflict Zones: A “Remote Survey” in Spin Boldak,Southeast Afghanistan

Remote survey using high-resolution satellite images allows archaeologists to study ancient landscapes in regions made inaccessible by ongoing conflict as well as in regions located between zones of better archaeological knowledge. Such studies frequently suffer from a lack of chronological information. This paper presents the results of remote landscape survey in the territory of Spin Boldak (“white desert”) in Kandahar province, Afghanistan, and methodological efforts to detangle the chronology of a landscape made inaccessible by conflict. The studied region crosscuts several environmental zones (desert, alluvial plain, river, and hills) and lies within an important corridor of movement toward mountain passes on the Afghanistan–Pakistan border. Morphological comparisons of surveyed sites to better-documented examples and synthesis of data from a variety of sources allow us to draw chronological and taphonomic conclusions about three types of documented sites: fortified enclosures, caravanserai, and mobile pastoral camps. These methods provide time depth to our understanding of the remotely-mapped landscape and allow us to consider Spin Boldak as a place shaped by local and regional historical processes rather than merely as a timeless thoroughfare between more intensively inhabited locales.     

Mundane mobilities,performances and spaces of tourism

The extension of information and communication technologies is purported to provide great opportunities for women, with the potential for empowerment and feminist activism. This paper contributes to the debate about women and cyberspace through a focus on the role of the internet in the lives of a group of technologically proficient, socially advantaged white heterosexual new mothers. The internet played a central role in providing virtual social support and alternative information sources which increased these women's real sense of empowerment in the transition to motherhood. Simultaneously, however, very traditional stereotypes of mothering and gender roles persisted. A paradox is evident whereby the internet was both liberating and constraining: it played an important social role for some women while at the same time it encouraged restrictive and unequal gender stereotypes in this particular community of practice. An examination of new virtual parenting spaces therefore has a contribution to make in understanding changing parenting practices in the new millennium.

Mobile Media as New Forms of Spatialization

Abstract

The physical space has historically served as an important support for human expression. However, the production of location-based information has been consciously used as means of social control by the hegemonic power, which decides what can be publicly displayed, and what should be hidden. With the development of mobile media, space has gained new dimensions, resulting in a sort of hybrid space where digital information overlays the physical space revealing what was previous unknown about a place. As mobile devices become increasingly present in our society, they should be understood as a social interface to our experience of space, serving not only as means to consume information, but also tools for communication. This paper discuss the current mobile media practices, such as mapping, urban electronic annotations, location-based mobile games, and smart mobs, which creates opportunities for new forms of human expression, reappropriations of space, and contestation of hegemonic power.     

Augmenting Phenomenology: Using Augmented Reality to Aid Archaeological Phenomenology in the Landscape

Explorations of perception using GIS have traditionally been based on vision and analysis confined to the computer laboratory. In contrast, phenomenological analyses of archaeological landscapes are normally carried out within the particular landscape itself; and computer analysis away from the landscape in question is often seen as anathema to such attempts. This paper presents initial research that aims to bridge this gap by using augmented reality (AR). AR gives us the opportunity to merge the real world with virtual elements, including 3D models, soundscapes, and social media. In this way, aspects of GIS analysis that would usually keep us chained to the desk can be experienced directly in the field at the time of investigation.
