Long-term performance evaluation of an earthen grouting mortar: the Nuraghic complex of Genna Maria,Sardinia

Abstract

This paper presents a critical assessment of the long-term performance of an earth-based material employed nine years ago in conservation work on a building of massive, Cyclopean-style construction at the Genna Maria Nuraghic complex in central-southern Sardinia (Italy). The material was used for filling the large gaps between stones in the masonry walls to create a barrier to ingress of water into the masonry walls. In situ observations and laboratory analyses were conducted on samples of the grouting material to assess its condition after nine years.     

The effectiveness of public participation in the environmental impact assessment process – a case study of the projected Sierilä hydropower station at Oikarainen,northern Finland

One of the most difficult challenges in environmental impact assessment (EIA) is the effectiveness of public participation. This article addresses this question by looking at evaluation criteria applied during the EIA process for a northern Finnish hydropower project. The problematics of public participation is discussed in connection with the EIA process and social impact assessment for the projected Sierilä hydropower station in the village of Oikarainen, near Rovaniemi, in northern Finland, during which the local population has been viewed as not being sufficiently competent as the project developer, Kemijoki Ltd. Nevertheless, carrying out an EIA seems to be a starting point in the long‐term process of increasing the effectiveness of public participation and the influence of local communities on hydropower planning processes in Finland.     

Prioritising Heritage Resources in a Time of Loss: Sea Level Rise and Archaeological Resources of the Middle Atlantic Region,US

ABSTRACT

The US Middle Atlantic region, known for its rich archaeological record and diverse topographic settings, is experiencing a range of climate change impacts, most notably: sea level rise and coastal erosion in its tidal zones. Documented palaeostratigraphic and palynological studies throughout the region provide a record of late Pleistocene/Holocene environmental response to changing climate, confirming observations from other disciplines that the magnitude of modern impacts exceeds past temporal and spatial patterns. The corresponding impact on archaeological resources is great, requiring a renewed effort to document threatened sites while also working with local and state governments to develop mitigation strategies. The Middle Atlantic Archaeological Conference (MAAC) created the Sea Level Rise and Storm Surge Committee to promote regional partnerships in site impact assessment and mitigation strategies. The network highlights the predicament of archaeology in this time of climate change: accelerated research and discovery in the face of catastrophic loss.     

U‐2 flights in the North: Western strategy,intelligence requirements and political risks

Reindeer herding in Scandinavia has in recent years been studied as a common‐pool resource problem. In such studies the size of the herds are often analysed in relation to issues like economics, demography, and technology. In this article the author discusses the size of reindeer herds in relation to social and organisational issues in the light of experiences from an environmental assessment.     

Brugge–Zeebrugge The New Belgian Harbour on the North Sea

Abstract

The history and prosperity of the Belgian city of Bruges has always been dependent on the sea. The growth of sea-borne traffic and the increasing size of vessels in recent years demanded new facilities to enable Belgium to exploit the natural advantages arising from its location. The construction of such port facilities during the last decade has employed the latest techniques in design, construction and environmental impact assessments. Contracts for the port development were drawn up to provide limits for quality control, timing and general but strict pricing, while enabling amendments during the course of the project. Now nearing completion, the major dredging and construction works have suffered no delays and will provide the most modern facilities in Zeebrugge, the port of the future.     

Organic Loss in Drained Wetland Monuments: Managing the Carbon Footprint

Abstract

The recent installation of land drains at Star Carr, Yorkshire, UK, has been linked with loss of preservation quality in this important Mesolithic buried landscape, challenging the PARIS principle. Historically captured organic carbon, including organic artefacts, is being converted to soluble organic compounds and less soluble carbon gases. At the same time sulphur and nitrogen compounds are oxidized to species that are chemically destructive of artefacts and ecofacts. Two of the carbon products, CO₂ and methane, are ‘greenhouse gases’ whose environmental impact can be costed in terms of carbon equivalents, which can be set against an assessment of the gain in agricultural productivity of the land arising from drainage, at Star Carr being the improved cereal crop. Wetland studies elsewhere suggest that such decay processes could be slowed by restoring the historic soil environment, and even reversed to create carbon capture, enabling the farmer to claim carbon credits.     

Modeling social interaction: Marital miscegenation in colonial Spanish America

Abstract

In this article, the author constructs new life tables for the white population of the United States in each decade between 1790 and 1900. Drawing from several recent studies, he suggests best estimates of life expectancy at age 20 for each decade. These estimates are fitted to new standards derived from the 1900–1902 rural and 1900–1902 overall death registration area life tables using a two-parameter logit model with fixed slope. The resulting decennial life tables more accurately represent sex- and age-specific mortality rates while capturing known mortality trends.     

Increasing Vocational Awareness through an 'Environmental Impacts of Business and Industry' Module

ABSTRACT

The initiative described in this paper is an undergraduate module called Environmental Impacts of Business and Industry. It has been taught at Roehampton Institute London since 1994. Its aims include increasing student awareness of the workplace, developing understanding of how environmental policies interact with working practices and equipping students with skills for investigating and reporting employment-related environmental issues. Students conduct an environmental assessment of a site-specific business or industry and produce a 3000 word case study report which identifies environmental impacts and makes recommendations for improving environmental performance. The paper first describes the departmental/institutional context and the development of the module. It then considers the structure and content of the module and the selection of case studies-illustrating them by reference to some of the lecturing material and work produced by the students.     

The Acoustics of Stringed Musical Instruments

Abstract

Attempts to understand the action of musical instruments at a level having some impact on the problem of musicians and instrument maker must face formidable unsolved problems in psychoacoustics as well as in classical physics. This review outline what is known about the physical properties of stringed instruments, with emphasis on the violin family, and tries to identify basic outstanding problem where progress may be hoped for within the next decade. One such area is assessment of the widely used simplest idealization of violin behaviour in which the driving at the bridge is assumed to be transverse, and the body is modelled as a 'black box' with one input and one output. Other major problem include the physical nature and psychoacoustical relevance of complex fine detail in the behaviour of the bowed string.     

Comparing expeditious procedures for the seismic vulnerability assessment on the European territorial context: reliability,feasibility, cost,and time consumption

ABSTRACT

The definition of strategies for the preservation and protection of cultural heritage is a topical issue, especially in view of the increasing relevance of the theme of seismic risk mitigation and reduction.

The prediction of the impact an earthquake could have on existing buildings requires the knowledge of their dynamic behaviour. The procedure to be adopted for this purpose is quite complex and onerous in terms of costs, time, and implementation, especially when the study concerns territorial areas rather than single buildings. The definition of methodologies aimed at respecting the principles of economic sustainability and preserving human life and architectural heritage is of paramount importance to assess seismic vulnerability using available resources. Rapid methods for the seismic vulnerability assessment, aimed at defining buildings vulnerability and intervention priority lists, must be implemented to guarantee the preservation of historical centers.

This article describes the application to some case studies of different methods aimed at creating fragility curves for the vulnerability assessment on the European territorial context. The comparison between a deterministic approach and a new probabilistic one is performed for all case studies, to define the most suitable methodology in terms of reliability and savings in cost and time.     

Framing the High North: Public Discourses in Norway after 2000

Abstract

The article presents an overview of the main public debates in Norway that can be said to have framed and defined the High North since the turn of the Millennium. It is based on a qualitative study of over 3000 articles published in four Norwegian newspapers issued between 2000 and 2006. Our discussion is structured around three overarching, interconnected narratives that we think capture the essence of the Norwegian public discourses on the High North between 2000 and 2006. These are “Fragments from the 1990s”; “The great narrative of the High North”; and “Mixing cold water with hot blood”. The first half of the 2000s is characterised by an almost total absence of the High North as a discursive and politically coherent concept. From 2004, however, usage grew fivefold, alongside an extensive, dynamic discursive mobilisation. When the Russians decided in 2006 to shelve the Shtokman project and critical voices were heard condemning Norway's environmental performance in northwest Russia, public opinion swung back again. A feeling of cold reality replaced the sense of optimism towards the energy potential of the north, and an exercise in collective soul-searching commenced – similar to that of the early years of the decade. We believe the type of discursive change we document in this article constitutes policy trends in connection both with the High North and with other sectors where policy is subject to intense public debate and appraisal. We hope that discourse analysis has enabled us to investigate and share how Norwegian public discourses on the High North are socially produced, framed and maintained but at the same time are always in flux and open to “new” directions which should be possible – at least in theory – to trace by going back in time.     

Veiqati Vaka Viti and the Fiji Islands Elections in 1999

ABSTRACT

The question of demographic decline in the Marquesas Islands is here reinvestigated through an integrated approach to the particular case of Ua Huka. We first attempt to propose a new population estimate for the period prior to European contact, thanks to an archaeologically based method that relies on the length of sleeping areas available in the housing structures recorded in the valleys. From this estimate, we then use ethnohistorical accounts to reassess local demographic evolution throughout the 19th century. This leads us to partly nuance the impact of Westerners, especially the introduction of diseases, which on Ua Huka appears to have been less critical than other factors such as sociopolitical conditions, including intense warfare, linked to unfavourable environmental conditions.     

What is scepticism and can it be found in the Hebrew Bible?

Abstract

This is the first installment of a two part study examining scepticism and irinic correlations in the joy statements of Qoheleth. In this article, a synoptic overview of scepticism is provided from Pyrrho to Descartes, Hume and Kant. The article then examines scepticism's methodology and provides a working definition followed by a critical assessment of the above. The article then examines both the general views of a sceptical tradition in the Hebrew Bible and Dell's specific view of scepticism in the Book of Job followed by a critical assessment of them. Finally, a conclusion is provided for this article.     

The Politics of Nature at the Former Auschwitz-Birkenau Concentration Camp

ABSTRACT

This article seeks to develop a new approach in Holocaust studies, namely an environmental history of the Holocaust. A case study of the former concentration camp at Auschwitz-Birkenau demonstrates the extent of the entanglement of the politics of memory and the politics of nature, or political ecology, to use Bruno Latour’s term. I suggest that memorials should be treated as an environment, and thus explored as an assemblage of human and nonhuman (f)actors. Analysing both the official preservation strategies adopted by the Auschwitz-Birkenau Memorial and Museum as well as artistic projects (including ?ukasz Surowiec’s Berlin-Birkenau), I consider commemorative practices’ environmental impact. My investigation thus primarily focuses on the role of the figure of the tree-as-witness in preservation work and in the use of powerful herbicides (namely Roundup) in preserving traces of the camp. This study could open the way to further comparative studies of ecocide and genocide.     

Bias in Fish Bone Recovery from Differential Collection Techniques and Its Impact on Cultural Interpretation in California

ABSTRACT

While studies on recovery bias are numerous in the literature, the current research focuses on defining best practices in field collection techniques to provide a more accurate representative of site constituents, particularly fish remains. Methods to determine best practices included use of 1/4-inch, 1/8-inch, and 1/16-inch mesh to process excavated material from 10 × 10?cm and 40 × 40 cm-sized bulk column samples and from a 1 × 1 m test unit. Fish remains were compared to determine density and diversity differences between the samples and how these different data sets may impact cultural interpretations. This research shows that while collection of larger column samples processed using a smaller mesh size provides a more robust data set, the taxonomic richness present in a 1 × 1 m test unit provides complimentary data that are critical to understanding subsistence trends as a whole.

Placing Masculinities and Geography

Introduction There has been an increasing focus in feminist and pro-feminist inspired studies on examining men, male subjectivities and masculinities in the decade since Gender, Place and Culture began publication. Our aim in this article is to provide readers with a brief overview of some of this recent research, and then to place these works within a critique of the Anglocentric character of geographic knowledge production. The article proceeds in the following manner. We begin with a brief definition of masculinity, in order to stress its temporal and geographical contingency. We follow this discussion with a brief review of some of the research on masculinities undertaken in the past two decades, with a particular emphasis on studies of the social and cultural geographies of masculinity completed in the decade since Gender, Place and Culture began publication. It is important to note that our review is far from exhaustive, but rather, more indicative. Our purpose here is to provide a context for our subsequent critique of a specific scaling of knowledge that constitutes much of the context for the way that work on masculinities is understood in Anglo-American geography.     

Depositional Context as the Foundation to Determining the Palaeolithic and Mesolithic Archaeological Potential of Offshore Wind Farm Areas in the Southern North Sea

Abstract

There is currently limited evidence on which to assess the submerged prehistoric potential in areas of renewable energy development. This paper presents a geomorphological approach to examine the Palaeolithic and Mesolithic archaeological potential in relation to the Round 3 offshore wind farm (OWF) areas of the southern North Sea. The depositional context and major stratigraphic correlations between the terrestrial sequence on east coast of Britain and offshore marine sequence of the southern North Sea are used to provide a first-order assessment for identifying horizons of archaeological interest in OWF zones. Using the examples Triton Knoll and East Anglia One OWF, the nature of renewable energy development on identified archaeological horizons is discussed, noting that any impact needs to be considered on a site-by-site basis. Studies are not only needed on the practical assessment of any development impact but also on the impacts of natural processes in OWF zones.     

A Critical Review of European and American Provisions for the Seismic Assessment of Existing Steel Moment-Resisting Frame Buildings

The publication of Part 3 of Eurocode 8 (EC8-3), dedicated to the seismic assessment of existing buildings, took place a decade ago. However, its application in engineering practice has been limited. Moreover, no studies have been conducted regarding the application of EC8-3 to steel structures. In this paper, a critical review and practical application of EC8-3 and ASCE41-13 are carried out. Issues related to the definition of the performance requirements, compliance criteria, and the consistency of the analysis procedures proposed by both standards are identified. Conceptual differences between both documents are highlighted, and several inconsistencies in EC8-3 are discussed.     

Archaeology in the age of the Anthropocene: A critical assessment of its scope and societal contributions

Abstract

Recent decades have witnessed heightened public and governmental awareness of the nature and scale of environmental challenges likely to face the planet over the course of the next fifty to one hundred years. Scholars from across a broad range of disciplines have been drawn into these debates and have begun to reorient their research towards finding solutions to some of the most pressing problems and to devising more sustainable and resilient livelihoods. Archaeologists, with their conventional orientation toward past events and processes have been rather slower to engage with these issues. Recently, however, there has been a steady shift within the discipline so as to incorporate more future-oriented perspectives, and ‘the use of the past to plan for a better future’ is rapidly becoming a common theme within archaeological research projects and publications. While welcoming some of these developments, this paper offers a critical assessment of the various claims that are now being made of archaeology's potential to help overcome current environmental challenges and its contributions to defining and understanding ‘the Anthropocene.’
