The Narrative Uses of Evidence

When scientific evidence is used in policy controversies, it is always embedded in narrative stories. The Narrative Policy Framework (NPF) is an empirical framework used to study the role of narratives in public policy. While the NPF has considered the relationship between evidence and narratives from different angles, it has not used a consistent approach in examining how evidence is embedded in narratives. This article develops a categorization of narrative uses of evidence. A narrative use of evidence is defined by the different roles that evidence plays in the plot of a narrative depending on which narrative element is addressed by a given piece of evidence. To distinguish different narrative uses of evidence, the article examines how competing coalitions use the Program for International Student Assessment (PISA) study in Swiss direct‐democratic campaigns on school policy. Quantitative and qualitative content analyses of newspaper articles and governmental documents show how evidence may relate to all main narrative elements and may play different roles in the plot of a narrative. The findings demonstrate significant differences in the narrative uses of PISA between coalitions related to the story types and narrative strategies that each coalition uses. Finally, the implications for future NPF research are discussed.

When Studies Collide*

Environmental epidemiology increasingly is being used as a foundation for environmental health policy. Since environmental epidemiologic studies have increased dramatically in number, approaches are needed to interpret them. Two approaches used in epidemiology are rules of evidence and meta-analysis. Rules of evidence pertain to the consistency, strength, uniqueness, and medical basis of the relationship between disease and risk factors such as chemicals. Meta-analysis is a systematic and rigorous approach to comparing studies and understanding their heterogeneity. Dioxins, benzene, and formaldehyde are three chemicals that are at the forefront of health policy debates. These chemicals illustrate some of the conditions under which researchers are drawn or are not drawn to approaches to compare studies. A meta-analysis was not conducted for dioxins or benzene, but was conducted for formaldehyde. Rather than addressing study comparisons, epidemiologic studies of dioxins are focusing on expanding the number of health effects studied and obtaining greater specificity for exposures, whereas studies of benzene are focusing on effects at low dose exposures. In the case of formaldehyde, meta-analysis has strengthened the evidence for some health effects beyond what individual studies could provide. Thus, whether rules of evidence and meta-analysis approaches to synthesizing information are used can depend upon where the debates are focused.     

Investigating the production and distribution of plain ware pottery in the Samoan archipelago with laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS)

This paper presents a provenance study of 170 ceramic artifacts and 21 ceramic tiles from three islands in the Samoan archipelago using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). Our analyses confirm that LA-ICP-MS can be used to differentiate between clay formations on a single island. We identify different distribution patterns for pottery recovered from lowland and highland sites on Tutuila Island. We also examine evidence for movement of pottery between islands, and find only limited evidence for such movement. Our findings suggest dynamic patterns of prehistoric interaction and site use that need to be evaluated with further data from across the archipelago.     

The Archaeology of Commoner Social Memories and Legitimizing Histories

In recent years, archaeologists have productively exploited historical documents and monuments as evidence for social memory and the selective writing, rewriting, and silencing of history for instrumental purposes. However, for a variety of theoretical and methodological reasons, less consideration has been given to such powerful uses of the past in the past by commoners in domestic contexts. In this article, we present a case study that demonstrates how the household remains of commoners can be used as rich, direct sources of evidence for the conscious manipulation and deployment of social memory. Our case study focuses on multiple lines of evidence from burials interred under a household patio at the pre-Aztec and Aztec site of Xaltocan between C.E. 1290 and 1520. Archaeological burial data, osteological analyses, a fine-grained chronology created with Bayesian statistical modeling of radiocarbon dates, and ancient DNA analyses are combined to reconstruct the household genealogical history inscribed by residents. This history—perhaps motivated by power and claims to land—entailed selective remembering and forgetting and the rewriting of the past of life on this house mound and was enabled by material mnemonics in the form of buried bones. Interestingly, this inscribed, instrumental genealogical history may have been structured by some of the same principles and representational canons that shaped pre-Hispanic pictorial genealogies used as evidence in colonial legal disputes.     

Stone tools for the hunt: points with impact scars from a Middle Paleolithic site in southern Italy

We present the find of impact scars on six Middle Paleolithic points from the rock shelter site of Oscurusciuto in southern Italy, dated to MIS 3. We review our knowledge of hunting weapons in the European Middle Paleolithic, the available evidence for the use of Mousterian points as spear tips and the interpretations of impact scars. Our identifications are based on comparisons to similar scars observed on experimental material and archaeological material of known function, made of the same raw materials (cryptocrystalline varieties of silica) as the points from the Oscurusciuto site. The scarce evidence available prior to our work suggested that at least some Mousterian points were used to tip hand-delivered spears already by MIS 6 (i.e. between 186 and 127 ka). The evidence from Oscurusciuto confirm that Neanderthals in Western Europe sometimes used Mousterian points to tip spears to hunt large and medium size mammals, like the fauna present at the Oscurusciuto site. The significance of this sample is not diminished by its small size, as indicated by a discussion of the factors that influence the frequencies of impact scars in different archaeological samples and a review of comparable evidence from residential sites of similar and younger ages.     

Garden plants in medieval Iberia: the archaeobotanical evidence

Of all the plants that were used in early medieval times, many were grown in gardens and orchards and contributed to the subsistence of medieval communities. Archaeobotany provides direct evidence of the range of species used either for food or for other purposes. In this contribution, we explore the evidence of garden produce in early medieval Iberia focusing on archaeobotanical data. First, we will analyse the available data, taking into consideration different types of preservation. Second, we will examine the diversity of species, trying to establish the uses and purposes of the taxa identified. Finally, we will discuss results within the better‐known wider European context.     

The identification of prehistoric dairying activities in the Western Isles of Scotland: an integrated biomolecular approach

The antiquity of dairying in regions considered to be marginal, such as the Western Isles of Scotland, has generated considerable debate. Complementary biomolecular methods are now available for identifying milk residues on ceramic vessels, which provides direct evidence for this practice in the past. A range of late Bronze Age and Iron Age ceramic cooking vessels were selected from two sites on South Uist, an island in the Outer Hebrides. The presence of milk proteins and lipids on a high proportion of potsherds confirms that these vessels were originally used to process dairy products. These data were integrated with evidence from the faunal remains and ethnographic accounts, in order to examine the wider significance and implications of dairy production in the Western Isles of Scotland during the first millennium BC. Further evidence from the pottery typologies and their depositional contexts were considered in order to comment on preparation and consumption practices.     

Direct evidence of the use of beehive products in pre-Roman Sardinia

Written sources and iconographic evidence suggest that honey and beehive products, used in culinary, medicinal, and technological functions since pre-Neolithic times, were likely known and used in Phoenician and Punic Sardinia. The role of these resources is nonetheless poorly understood because no direct evidence survives on a macroscopic level. Significant advances in the knowledge about beeswax and beehive products processing in the past have been offered in recent decades by organic residue analyses (ORA), an approach that enables the characterisation of surviving chemical compounds or suites of compounds that provide information relating to human activity in the past. The relatively recalcitrant nature of lipid compounds comprising beeswax means that this commodity is among the products that can be unambiguously identified through ORA. Here we present and discuss the results of analyses undertaken on 368 pottery sherds from Phoenician and Punic Sardinia (eighth to third century BCE). These analyses offer direct evidence for the presence of beehive products on the island, suggesting the use of honey for culinary purposes in pots, and possibly connecting one specific vessel category with beeswax decanting during beekeeping and honey production processes. Our results also now clearly illustrate the widespread use of beehive products in pre-Roman Sardinia.     

Early hominid hunting,butchering, and carcass-processing behaviors: Approaches to the fossil record

A major aim of paleoanthropology is to learn what ancient behaviors were related to the acquisition, processing, and consumption of meat and when these behaviors arose. For this reason, studies focusing on purported early hominid hunting and butchery sites are important if rigorous criteria for recognizing such sites are used. Different criteria currently used as evidence of hominid involvement with ancient bones are reviewed and it is concluded that the presence of cutmarks, verified by scanning electron microscope (SEM) inspection, is the most reliable. Successful application of this criterion depends upon a thorough knowledge of the normal variations in microscopic morphology of different types of marks that are found on bones. Therefore, variations in microscopic and gross morphology within and among a large sample of known stone tool cutmarks, carnivore tooth scratches, and rodent gnawing marks are documented. The effects of sedimentary abrasion, as caused by fluvial transport of bones, are also presented. Guidelines are presented for using microscopic criteria to identify unknown marks on fossils and possible applications of this approach are discussed. Further, it is suggested that evidence of hominid carcass-processing activities can be placed into one of three ranked categories of certainty according to the type of data used. Explicitly stating the category and type of evidence used to deduce hominid activities, and by extension to define site types (i.e., butchery, kill, base camp), may improve the clarity of hypotheses about and interpretations of early hominid behaviors.     

Healed limb amputations in human osteoarchaeology and their causes: A case study from Ipswich,UK

An adult male skeleton of Medieval date from Ipswich, UK, shows amputation of the right hand. The morphology of the bones suggests a quiescent stump, in which healing had been completed some time before death. Osteometric, morphological and radiographic data show that the mutilated limb continued to function but was used to a lesser degree than the intact side. A review of some of the literature on the osteoarchaeological evidence for healed limb amputations showed that interpretations generally fall into three broad categories: surgical intervention, judicial punishments and blade injuries. In the Ipswich case the skeletal evidence offered few clues as to the reasons for the mutilation, but historical evidence suggested a possible personal identification for the burial and that the cause of the amputation was a blade injury sustained as a result of a violent assault.     

The role of shellfish in hunter–gatherer societies during the Early Upper Palaeolithic: A view from El Cuco rockshelter,northern Spain

The role of coastal resources in the subsistence strategies of Palaeolithic human populations has only recently become an important topic in Old World archaeology. Information on the exploitation of these resources, both as foodstuffs and symbolic elements, can be used to infer the emergence of modern human behaviour as well as to track the diversification and intensification of human diet over time. The excavations carried out at El Cuco rockshelter, located in northern Spain have provided evidence for the exploitation of marine resources during the Early Upper Palaeolithic. The accumulation of Patella shells at El Cuco provides the largest accumulation and the first clear evidence of collection and consumption of molluscs during the Aurignacian on the Atlantic Façade of Europe. A deposit of ornamental shells appeared in a very homogeneous context dated to the Gravettian, suggesting that the shells belonged to the same item. The analysis of this evidence has allowed us to conclude that marine resources were systematically used at least from the beginning of the Upper Palaeolithic in the region. However, a comparison with the Mesolithic shows that intensive shellfish gathering did not occur until the end of the Upper Palaeolithic. Regarding the ornaments, it is interpreted that the identified shell beads were used as social or personal status markers.     

Research on the history of the third world in Scandinavia

The aim of this paper is to challenge some of the established views on monetary and economic aspects of medieval Norwegian history. This challenge is not only based on a different understanding of the evidence, but also on new interpretations of documentary and numismatic evidence. Contrary to what has been the general understanding I argue that money was available, and it was, in longer periods of time, available within a framework of a well organized monetary system with large coinages. In the second half of the 12th century, coins became distributed and used among a larger group of people in rural areas than ever before. In market places and towns, money economy was emerging in the 11th and 12th, and probably seen partly in effect in the 13th and 14th century. If we accept the evidence for coinage and the use of money as being widely distributed, or even accept it partly, it opens up a range of new perspectives to use as starting points for understanding medieval monetary and economic history in Norway.     

The Pyrenean Neighbour; or,the Vicinal System in the Western Pyrenees

Excavations have recently produced valuable new evidence for the structural types used in the vernacular architecture of lowland and eastern Britain during the sixth-eighth centuries A.D. The evidence from a number of contemporaneous sites suggests that a highly characteristic building tradition was in widespread use. The identifying features of this building tradition are defined and its affinities discussed.     

New Evidence for Seasonal Human Presence at the Early Mesolithic Site of Thatcham,Berkshire, England

Important new seasonal evidence has been derived from the early Mesolithic site at Thatcham, Berks based upon tooth development stages in dentally immature red deer (Cervus elaphus). Radiographs and visual examination of the developing mandibular molars and premolars have been used to provide an accurate indication of age at death by comparing them with modern known age specimens. Knowledge of their age when killed indicates at what time of the year humans were present at the sites. Determining whether a site was occupied seasonally or year round is critical to subsequent interpretations of human economic and social activity. For the first time clear seasonal evidence has been derived from this important early Mesolithic site. Based on this new line of enquiry there is strong evidence for winter killing red deer at the site. The winter evidence at Thatcham may indicate presence at the site by hunters during the winter months for the express purposes of killed red deer. Alternatively, and more likely, the site was visited for a variety of economic and social purposes at all times of the year.     

Iron knees in wooden vessels—an attempt at a typology

Knees were brackets in the structure of a wooden ship. They were introduced in the second half of the 18th century and were in common use for naval and merchant ships in the 19th century. They were fashioned in various designs. A typology of these is proposed based on archaeological and documentary evidence. Iron knees could used to assist the dating of unidentified shipwrecks.     

Flaked-Stone Artifacts in Greece during the Historical Period

Abstract

The evidence for historical flaked-stone artifacts in Greece is summarized. In recent years a number of such artifacts have been recognized in stratified deposits of the early Iron Age, the Protogeometric, Geometric, and Classical periods. Historical flaked-stone artifacts were probably used for making agricultural tools and were low-cost substitutes for metal. The evidence indicates that an ancient Greco-Roman flaking tradition may bridge the gap between the latest Bronze Age tradition and the gun-flint and threshing sledge flint knappers of recent times. An economic model of innovation is used to explain the use of stone tools after the introduction of metal.
