Innovative application of portable X-ray fluorescence (XRF) to identify Göktepe white marble artifacts

An efficient and non-destructive method to classify white marble artifacts by using a hand-held, portable XRF analyzer (pXRF) is here reported. The identification is based on the uniquely high strontium content of this marble and has been verified by testing 32 artifacts, most of which had already been provenanced, using conventional micro-destructive analyses. Besides strontium, other potential provenance indicators, such as manganese and iron, were analyzed and their concentration values obtained after empirical calibration of the instrument by using 17 quarry samples of known composition. The results show that Göktepe/non-Göktepe discrimination is almost always possible (30 artifacts) and that additional analyses are required only when the Sr value is at the lower edge of the Göktepe field (2 artifacts). The success of the method, however, resides in the particular composition relative to trace elements of Göktepe and is not easily extended to other marble varieties. Main reasons are related to insufficient accuracy at low concentration values, intrinsic trace variability of marble artifacts, surface effects that may produce not representative results. Interest in the method therefore is tightly linked to the exceptional importance of Göktepe as a sculptural marble, in which case, detailed data, obtained with a fast and totally non-destructive method, may provide relevant information concerning chronology, workshops, and places of production of the artifacts.     

Soybeans,Development and Conservation on the Amazon Frontier

Bolivia's rate of deforestation throughout the 1990s was among the most rapid anywhere in the Amazon Basin. This drastic clearing stood in sharp contrast to the relatively slow rates of landscape change that had prevailed in previous decades. This article reviews the models used for explaining deforestation, and argues that the new context of globalization, structural adjustment, regional integration and rapid technological change contributed to accelerated forest cutting during the 1990s. The author suggests that many environmental policy approaches developed during the 1970s and 1980s no longer address the current clearing situation effectively, and that today's frontiers differ profoundly from previous ones. The widely held idea that intensive production per se reduces forest destruction may not be valid on tropical agro‐industrial frontiers, such as the soybean zones of Bolivia and Brazil.     

COMPANY WELFARE PROGRAMMES AND INDUSTRIAL MODERNIZATION IN FINLAND

Prior to the modern welfare state, many large companies provided extensive welfare programmes for their employees. In this article, such welfare programmes – or corporate welfarism – in Finnish manufacturing firms in the early 20th century are the focus of attention. I analyse the content of these programmes and how they changed over time as part of the modernization and professionalization of management and industrial and societal change. I also discuss how company managers perceived the role of welfare provisions in corporate development and what happened with these programmes when the first steps towards the modern welfare state were taken. I show that these programmes started as a necessity and part of industrial paternalism, but gradually became part of labour management, in particular for the creation of a loyal workforce and productivity improvements. These programmes often developed in collaboration with local municipalities, which led to intertwined relationships at the local level, marked by both trust and tension in local communities. Once general welfare reforms emerged, companies often abandoned their voluntary programmes, while some services were taken over by the municipalities. I also ask to what extent these programmes were managerial strategies to counteract growing state involvement in their affairs.     

Florence baptistery: chemical and mineralogical investigation of glass mosaic tesserae

A recent restoration of the mosaics of the Baptistery in Florence enabled the collection and analysis of a group of glass tesserae. Twenty-three tesserae, dated between the end of the 13th century and the first half of the 14th century, showing different colors were sampled and analyzed to identify the raw materials, colorants and opacifiers employed in their production.     

Interpretation of archaeological small-scale features in spectral images

The paper's focus is the use of spectral images for the distinction of small archaeological anomalies on the basis of the authors work. Special attention is given to the ground truthing perspective in the discussion of a number of cases from Norway. Different approaches to pattern-recognition are considered in the light of the increasing availability of hyperspectral images that are difficult to analyse using visual inspection alone.     

World Heritage and Tourism Innovation: Institutional Frameworks and Local Adaptation

Abstract

The interest in heritage as a tool for destination development has recently been substantial in Sweden, especially when it comes to receiving World Heritage (WH) status. The possibility of using the WH brand in developing tourism products and marketing destinations has great potential for many heritage destinations. The aim of this paper is to discuss innovation processes within heritage tourism. The focus is on the role of WH status as a factor influencing innovative practices at different Swedish WH sites. This study uses qualitative methods, such as interviews and analysis of written material from five selected Swedish WH sites, with in-depth analysis of the Great Copper Mountain in Falun. To what extent does WH status change the preconditions for tourism development at WH destinations? What is the role of institutional frameworks in this process? This paper will show how WH may facilitate tourism innovation mainly through developing new products and marketing strategies, but also by institutional innovations concerning new forms of collaboration and networks.     

Liminality in nature-based tourism experiences as mediated through social media

Abstract

The intersection between social media, liminality and nature-based tourism experiences hasn’t been the focus of previous tourism research. Such intersection, on the other hand, is illustrative of how social media relate to the constitution and performance of tourism spatialities, tourist identities, storytelling and place-making, and can lead to relevant theoretical contributes. We aim to investigate how liminality is expressed in relation to nature-based experiences by tourists on social media, and what role social media plays in mediating liminality during nature-based tourism experiences. The analysis is based on a participatory netnography of images and text posts, as well as online interviews with users of the popular social media Instagram. Findings show that the expression of tourism experiences in nature is closely related to specific notions of liminal otherness as opposed to the urban life and the everyday, where nature and wilderness are expressed as related to the genuine, the authentic and a true inner self. Creative combinations of pictures, captions and hashtags make it easier for tourists to express the contrast between the natural landscape and the everyday landscape once they returned home. These combinations also relate closely to performances of resistant and alternative selves and communities. At the same time, such performances are mediated and contested between freedom of self-expression, surveillance and social norms, an aspect that makes their liminal nature ambiguous.
