Monitoring of Shipwreck Sites

A three-year research project, The Monitoring of Shipwreck Sites (MoSS), was initiated in 2001 as a partnership between several European countries: Finland (project leader), Germany, Holland, United Kingdom, Denmark and Sweden. The aim was to establish a suitable programme for the monitoring, safeguarding and visualizing of shipwreck sites, based on the investigation of three wrecks located in the Baltic and North Seas. Phase I involved the monitoring process, with the investigation of physical, chemical and biological factors that will help to identify potential threats to buried and exposed archaeological material. Phases II and III considered safeguarding and visualizing of shipwreck sites.

ANALYSIS OF A DYNAMIC RESIDENTIAL LOCATION CHOICE MODEL WITH TRANSACTION COSTS*

ABSTRACT. This paper incorporates transaction costs in a residential location choice model. An individual's choice is assumed to be an outcome of a two-stage process: a decision to change, or to undertake a transaction and, conditional on a change occurring, a choice of a new alternative. The dynamic choice model is aggregated to yield a Markovian model of residential location patterns. It is shown that recent contributions to dynamical urban modeling correspond to special cases of the deterministic version of this model. The Markovian model is used in a theoretical analysis of the influence of transaction costs on the properties of the stationary state. The effects of residential mobility rates and of interdependencies among individuals, caused by supply-side and density-related interactions, are also analyzed. It is shown how these dynamical factors modify the stationary state, thereby demonstrating the type of errors which may occur with static models that omit them.     

The Ambiguities of Christian Sexual Discourse in Post‐War Britain: The British Council of Churches and Its Early Moral Welfare Work

This article extends and develops recent historical discussion on the relationship between British Christianity, sexuality, and modernity, proposing some ways forward for future scholarship. Recent accounts have concentrated on liberal Anglican positions on issues of sexuality, but here the focus is on the British Council of Churches, its early moral welfare work, and interdenominational efforts to reconsider Christian sex teaching in the immediate post‐war years. While examining broader trends towards positive statements about sex and attempts to assemble self‐regulating sexual citizens in Christian moral welfare thinking, the article suggests that, far from a narrative of relatively untroubled and gradual acceptance of progressive Christian views on sex, this was a halting and uncertain process. The article reflects closely on the complexities of post‐war Christian attempts to work with new ideas about sexuality and to formulate their own version of them, the difficulties and ambiguities involved in developing a cogent position in a debate where Christian opinion was so fiercely divided, as well as the complicated nature of institutional decision‐making. As a case study, the British Council of Churches reflects earlier, problematic attempts to alter Christian sex teaching, as well as the unfolding of later difficulties for the British churches.     

Inconspicuous Consumption: Non-Display Goods and Identity Formation

In the study of ancient material culture, archaeologists have primarily focused on the use of objects for display and communication. This social function of material culture could only have developed on the basis of individual cognitive capacity for the use of goods as materializations of symbolic behavior. To explore the deeply held relationship of identity to material culture, this paper focuses on goods that are utilized away from the gaze of others. Using examples from the ethnographic present such as pharmaceuticals, underwear, and hygiene products, I develop the idea of “reflexive identity” to describe how people use material objects in private to define themselves prior to and independent of their social roles as perceived by others. The act of daily identity creation and affirmation through goods, particularly those that are inexpensive and disposable, indicates the extent to which human cognition and psychological sense of self are inextricably linked to the handling of material culture. The archaeological application of a reflexive identity enables us to understand how ordinary goods are a fundamental component of identity formation prior to and independent of individuals’ engagement with others.     

Land and Sea Tenure at Erub,Torres Strait: Property,Sovereignty and the Adjudication of Cultural Continuity

Approaching property as social practice, and native title as a confluence of indigenous, ethnographic, and legal discourses, we address two themes: firstly, the ethnocentrism of the state's division of ‘property’ from ‘jurisdiction,’; applied to deny indigenous societies' practice of the latter; and secondly, the contradictions inherent in judicial evaluation of continuity and discontinuity in indigenous law and custom. We explore the relationship of ‘home place’ to tenure at Erub, where island, reef and ocean comprise a cultural and experiential continuum. Rights across a full spectrum of material/symbolic resources involve a dynamic tension between principles of exclusion and incorporative reciprocity. The issue of how to balance more particular against more collective rights is at play with each nesting of more local into more inclusive socio-territorial identities: from households and lineages, through island communities, sub-regional island groups, and Torres Strait regionally, to the encapsulating state and evolving international orders. At Erub, an island community long regarded as a vanguard of creolization for Torres Strait, newcomers have by-and-large been assimilated to indigenous systems of land- and sea-holding and authority. The connection between people and territory is a complex practice of social identities and interests responding to political opportunity, according to cultural forms that manifest substantial and traceable continuities to indigenous arrangements, as innovation has proceeded. The continuities appear sufficient to satisfy criteria for native title recognition as articulated in the Mabo decision, but the criteria themselves are too narrowly based to accommodate the processual dynamics of evolving culture and tradition. A reordering of territorial jurisdiction, predicated on the principle of Islander consent to development activities in their homelands/seas, would provide more authentic conditions for cultural autonomy.     

Mare Nullius: Indigenous Rights in Saltwater Environments

This article uses two case studies to illustrate the subjection of indigenous peoples’ marine territories to a ‘double jeopardy’ of exclusion — jurisdictional and proprietary — through the legal and administrative practices of European ‘settler’ states in Australia and Canada. While the fiction of terra nullius as a legal rationale for refuting indigenous rights of property and governance has steadily eroded in recent decades, its counterpart mare nullius has proven, so far, more resistant. The authors examine how state conceptions of jurisdiction, property and boundary‐making in coastal areas accomplish the distortion and fragmentation of the coastal and marine spaces of Torres Strait Islanders in northern Queensland, Australia, and of the Cree and Inuit peoples of James and Hudson Bays in northern Que´bec, Canada. Assumptions of land–sea continuity underlie these peoples’ cultural constructions of coastal and marine environments. In examining the progress that each has made in reasserting ownership and control of coast and sea, it seems that recognition and reinforcement of their institutions for managing marine spaces and resources offer the best prospect for reconnecting fractured jurisdictional domains, and for bringing about social equity, environmental protection, and self‐determined regional development.     

Exploring patterns of movement suspension in pedestrian mobility

One of the main tasks in analyzing pedestrian movement is to detect places where pedestrians stop, as those places usually are associated with specific human activities, and they can allow us to understand pedestrian movement behavior. Very few approaches have been proposed to detect the locations of stops in positioning data sets, and they often are based on selecting the location of candidate stops as well as potential spatial and temporal thresholds according to different application requirements. However, these approaches are not suitable for analyzing the slow movement of pedestrians where the inaccuracy of a nondifferential global positioning system commonly used for movement tracking is so significant that it can hinder the selection of adequate thresholds. In this article, we propose an exploratory statistical approach to detect patterns of movement suspension using a local indicator of spatial association (LISA) in a vector space representation. Two different positioning data sets are used to evaluate our approach in terms of exploring movement suspension patterns that can be related to different landscapes: players of an urban outdoor mobile game and visitors of a natural park. The results of both experiments show that patterns of movement suspension were located at places such as checkpoints in the game and different attractions and facilities in the park. Based on these results, we conclude that using LISA is a reliable approach for exploring movement suspension patterns that represent the places where the movement of pedestrians is temporally suspended by physical restrictions (e.g., checkpoints of a mobile game and the route choosing points of a park).     

One Landscape, Many Tenants: Uncovering Multiple Claims, Visions and Meanings on the Theban Necropolis

The archaeology of the Theban Necropolis is well documented. Under represented in the literature are the studies which deal with the meaning of the site to the multitude of contemporary users who interact with the heritage landscape and with each other in the designated archaeological zone. This article will investigate how different stakeholders engage with the heritage ‘space’ and invest it with multiple meanings. By exploring the areas of agreement, difference and contradiction, we hope to show how contemporary experiences and future visions for the management of global heritage at the Theban Necropolis can be analogous and simultaneously worlds apart.     

Spatial distribution of innovation networks,technological competencies and degree of novelty in emerging economy firms

This paper analyses the relationship of the accumulation of technological competencies at the firm level, the spatial distribution of the firm's innovation networks and the degree of novelty of product innovation. Firm-based primary data collected in two innovative regions in emerging economies are used to predict higher degrees of novelty in emerging economy firms. Similarly to advanced economy firms, the results show that international linkages are associated with higher degrees of novelty. However, new-to-the-world innovation in emerging country firms is fundamentally externally driven, suggesting that international linkages seem to be a compensating mechanism for the initially lower technological capabilities rather than a complementary source of knowledge.     

Fishing gear from the Roman period in the Netherlands: An overview

This paper presents an overview of fishing gear recovered from Roman period sites in the Netherlands. Fish hooks, line sinkers, net sinkers, floaters, wickerwork fish traps, canoes with live wells and fish tanks have been identified. These artefacts provide additional insight into the widespread practice of fishing and thus of fish consumption during this time period and is a valuable addition to research on archaeological fish bone remains.
