Methods to Create a Longitudinal Integrated Demographic and Geographic Database on the Micro-Level

Abstract

The authors develop a methodology to create databases that can be used to add micro-level geographic context to longitudinal historical demographic analyses. The method transforms geographic objects as snapshots (digitized from historical maps) into temporal representations of longitudinal object lifelines and links individuals to these geographic objects. The methodology is evaluated via a case study using historical data from the Scanian Economic Demographic Database. The authors link approximately 53,000 individuals in five parishes for the period 1813–1914 to the property units in which they had lived. The results of this study are a unique contribution in terms of linking individuals to micro-level longitudinal geographic data over such long periods. Thus, these data may provide new knowledge for historical demographic research.     

LiDAR-aided reconnaissance and reconstruction of lost landscapes: An example of freshwater shell mounds (ca. 7500–500 cal b.p.) in northeastern Florida

Abstract

LiDAR datasets, from which high-resolution topographic maps can be generated, are becoming commonplace in archaeological analyses. Like any remote sensing technique, LiDAR records only a limited range of phenomena and the data are a snapshot of ground conditions at the time of collection. The temporally specific nature of LiDAR is problematic at sites with postdepositional destruction. This paper presents a method for identifying and recovering lost landscapes by combining LiDAR, archival aerial photographs, historical observations, and fieldwork. This method was developed to reconstruct the topography of ancient shell mounds constructed by hunter-gatherers on the St. Johns River in northeastern Florida (ca. 7500–500 cal b.p.) and altered by modern land use. The reconstructions demonstrate the influence of ancient communities on modern landscapes and can be used as a basis for further analyses of hunter-gatherer land use, social interaction, and cosmology.     

An alternative approach to hab 1,2‐2,20

Abstract

In the first part the ideological nature of the OT historical narrative is stressed, which means that it is hardly usable as a historical source alone. Therefore, in the second part three demands are formulated should we decide to use an OT text in a historical analysis: 1) the event we want to investigate has to be mentioned in the OT, 2) must correlate with material from archaeological excavations, and 3) must be mentioned in at least one external written source. The final part is devoted to an overview over the Scandinavian excavations at Tel Fukhar, Jordan.     

Record linkage in the Cape of Good Hope Panel*

Abstract

In this article, we describe the record linkage procedure to create a panel from Cape Colony census returns, or opgaafrolle, for 1787–1828, a dataset of 42,354 household-level observations. Based on a subset of manually linked records, we first evaluate statistical models and deterministic algorithms to best identify and match households over time. By using household-level characteristics in the linking process and near-annual data, we are able to create high-quality links for 84% of the dataset. We compare basic analyses on the linked panel dataset to the original cross-sectional data, evaluate the feasibility of the strategy when linking to supplementary sources, and discuss the scalability of our approach to the full Cape panel.     

PATIENT CASE RECORDS IN MEDICAL AND FAMILY HISTORY: EXAMINING THE RECORDS OF THE ROYAL FREE HOSPITAL

Abstract

The purpose of this article is to highlight the value and potential of patient case records as an historical source. Previous histories of the hospital (and of other healthcare providers more generally) have neglected to consider the patient. This is partly as a result of the ‘history from above’ approach of past histories which have focused on the founders and medical staff of such institutions and never on the people who were treated. During the early 1990s Porter called for the patient to be brought into the focus of medical history, and Risse and Warner drew attention to patient case records as a means of doing so. In the near twenty years which has passed since, however, patient records have still not been utilized by historians and the patient remains largely absent from history. By using the project ‘Royal Free Hospital Patient Case Records’ as a working example, this article will illustrate the benefits of using these records as a source as to patient identity, experience of medical treatment, use of the medical market, and life-cycle of individual, family, and community ill-health. The type of information the historian can extract from patient case records will be discussed and the example sampling method explained. The wider use and potential of patient records in history will then be considered and some practical advice given to help prepare historians to use such records to fill the void that is the history of the patient.     

Simple strategies for improving inference with linked data: a case study of the 1850–1930 IPUMS linked representative historical samples

Abstract

New large-scale linked data are revolutionizing quantitative history and demography. This paper proposes two complementary strategies for improving inference with linked historical data: the use of validation variables to identify higher quality links and a simple, regression-based weighting procedure to increase the representativeness of custom research samples. We demonstrate the potential value of these strategies using the 1850–1930 Integrated Public Use Microdata Series Linked Representative Samples (IPUMS-LRS)—a high quality, publicly available linked historical dataset. We show that, while incorrect linking rates appear low in the IPUMS-LRS, researchers can reduce error rates further using validation variables. We also show how researchers can reweight linked samples to balance observed characteristics in the linked sample with those in a reference population using a simple regression-based procedure.     

From Methodology to Ontology: Interdisciplinarity as a Principle of Constitution of Objectivity—Reflections from the Study of American Philosophy

Summary

The idea of interdisciplinarity can be articulated in different ways. The aim of the article is to criticise the view that interdisciplinarity is to be treated as a quality of the historian's approach to his subject-matter, and to argue for a constructivist interpretation of that notion. A constructivist account of interdisciplinarity relies on the thesis that the latter is one of the manifold ways in which it is possible to give sense to the historical records of which the historian wants to gain knowledge. In the paper it is maintained that the function of the notion of interdisciplinarity is to account for the clash of languages that can be found when disciplines converge. This new paradigm is highlighted by taking into consideration the history of American pragmatism.     

Linking Scottish vital event records using family groups

Abstract

The reconstitution of populations through linkage of historical records is a powerful approach to generate longitudinal historical microdata resources of interest to researchers in various fields. Here we consider automated linking of the vital events recorded in the civil registers of birth, death and marriage compiled in Scotland, to bring together the various records associated with the demographic events in the life course of each individual in the population. From the histories, the genealogical structure of the population can then be built up. Rather than apply standard linkage techniques to link the individuals on the available certificates, we explore an alternative approach, inspired by the family reconstitution techniques adopted by historical demographers, in which the births of siblings are first linked to form family groups, after which intergenerational links between families can be established. We report a small-scale evaluation of this approach, using two district-level data sets from Scotland in the late nineteenth century, for which sibling links have already been created by demographers. We show that quality measures of up to 83% can be achieved on these data sets (using F-Measure, a combination of precision and recall). In the future, we intend to compare the results with a standard linkage approach and to investigate how these various methods may be used in a project which aims to link the entire Scottish population from 1856 to 1973.     

Preparing Geography,Earth and Environmental Science (GEES) Students for Employment in the Enterprise Culture

Maps and related graphics are important means of representing key issues in development education and related themes. This paper examines the use of world maps in materials used in teaching development in higher education and concludes that many are not 'fit for purpose'. Many of these maps create false connotations, which can lead to misleading understandings of key issues.     

Paper 5: Historic Mortars from the Coudenberg Archaeological Site: Characterization and Source of Raw Materials

Abstract

The characterization of historic mortars by means of a concise methodology of material analyses can provide crucial information with regard to the origin of the raw materials and the ancient mortar technology. For the analysis of the historic mortars of the Coudenberg archaeological site, the methodology consists of optical and scanning electron microscopy, simultaneous thermal analysis, and an acidic treatment. These analyses were carried out on a total of seventeen samples lifted from various areas in the site, in function of the building chronology resulting from a historic built investigation. The type of binder and aggregate as well as their volumetric ratio were determined.

Both binder and aggregate present distinctive features, which made it possible to identify the probable geological provenance of the raw materials. The observations are verified with available historical records regarding the construction of the main banqueting hall — the Aula Magna — and the use of raw materials such as limestone and sand for the production of lime and construction purposes.     

Radiocarbon Dating and the Historical Archaeology of Korea: An Alternative Interpretation of Hongryeonbong Fortress II in the Three Kingdoms Period,Central Korea

Relying heavily upon historical records to build archaeological chronologies, many Korean historical archaeologists question the utility of radiocarbon dating. To challenge this tendency, we test a model based on historical records by analyzing radiocarbon dates. We dated two bulk samples from Hongryeonbong Fortress II, Seoul, South Korea, which is known historically to have been occupied between a.d. 500 and 551. By dividing bulk samples into smaller aliquots, we dated 40 subsamples and statistically estimated consensus dates. The consensus dates do not support expectations of the historical model, as they do not lie within the temporal range provided by historical records. We propose an alternative model that explains both the radiocarbon dates and the historical records. It is suggested that radiocarbon dating can be successfully applied to the reconstruction of historical periods and is a way of mitigating possible biases of models based solely on historical records.     

The Fabulous Tales of the Common People,Part 1: Representing Hadrian’s Wall

Abstract

Hadrian’s Wall is one of the most instantly recognizable ancient monuments in the UK. This paper explores the historical and contemporary visualization practices which have created this iconic image. Moving between the disciplines of archaeology, cultural geography, and heritage and tourism studies, the paper draws upon a variety of data sources such as paintings, photographs, models, and reconstructions to consider how the Wall is visually represented within contemporary public discourse. The paper focuses on digital photography and considers the ways in which images create and sustain particular readings of the Wall’s function and significance. These contemporary representational practices demonstrate strong continuities, and earlier images are used to provide historical context. Emphasis is placed on the monument’s landscape setting in visual representations and the importance of this environmental context for readings of the Wall’s cultural and political significance. The present paper deals primarily with representations of the Wall, but it is argued that these representational practices are also fundamentally embodied. The physical encounters of visitors and archaeologists will be considered in greater detail in the second part of this study (Witcher, forthcoming).     

Textual context in the history of political thought and intellectual history

ABSTRACT

We can easily misread historical texts if we take ideas and passages out of their textual contexts. The resulting errors are widespread, possibly even more so than errors through reading ideas and passages out of their historical contexts. Yet the methodological literature stresses the latter and says little about the former. This paper thus theorises the idea of textual context, distinguishes three types of textual context, and asks how we uncover the right textual contexts. I distinguish four kinds of textual-context error, and offer practical tips for avoiding these errors. However, the beating heart of this paper is the history–philosophy debate: in contrast to the prevailing assumption that historical and philosophical analysis are fundamentally different, I show that a commitment to textual context, which should be entirely uncontroversial, also commits one to think philosophically.     

What Can Causal Process Tracing Offer to Policy Studies? A Review of the Literature

Causal process tracing (CPT) has emerged as an important method of causal inference in qualitative social science research, most notably in case study research designs. There is now a considerable literature on the aims, philosophical groundings, and methods of process tracing. This paper reviews the CPT literature to assess what new directions it may suggest for policy studies. The first part of the paper sets out the methodological advantages CPT offers in building and testing theories of policy change, most notably in supporting a theoretical pluralism to address the problem of complexity in policy studies. Building on recent scholarship across the social sciences, the second part examines step by step the recently minted “best practice” for undertaking CPT in policy studies. This part includes discussion of the possible pitfalls of CPT as a method; common errors involved in its use are set out and minimization strategies offered. In particular, while acknowledging the usefulness of Bayesian tests for causality as heuristic devices, we emphasize the limitations of applying such tests in practice. Possible correctives are suggested. The final part of the paper speculates more generally on the potential of CPT to improve our investigation of patterns of policy change over time.     

Ming dynasty maritime provisions transport during the second stage of the East Asian War (1597–98)

Abstract

This article discusses the issue of the Ming army's maritime shipping of supplies during the second stage of the East Asian War of 1597–8. Despite the lack of historical sources and difficulty in finding accurate numbers, Zhang Yangmeng's 張養蒙 memorials include records of maritime transport decisions, implementation, effectiveness, and limitations and are of great help to filling in the blank areas of research in Ming army logistics.     

3D imaging of Skoteino Cave,Crete, Greece: Successes and difficulties

Abstract

Interpreting cave use, especially from antiquity, requires the perception of subterranean space in all dimensions (floor to ceiling to lateral extent) including spatial variability resulting from geological factors. Subterranean conditions, coupled with variable atmospheric conditions, create a special environment not readily conveyed by conventional mapping techniques limited to two-dimensional floor plans. Skoteino Cave in north central Crete, Greece was used as a ritual and refuge site in the Bronze Age and later. Mapping of the cave attempted to depict and interpret prehistoric and historical use of this space by employing two mapping techniques: EDM total station mapping and terrestrial/point cloud laser scanning. Comparisons with earlier methods used to map cave show the advantages and disadvantages of various mapping schemes. To date, this was the first use of three-dimensional (3D) scanning to explore the complex shapes and space of a subterranean archaeological site on Crete (and the second such use in Greece), and this use demonstrates its own consequent successes and difficulties.     

New Methods of Census Record Linking

The Minnesota Population Center (MPC) has released linked datasets through its NAPP and IPUMS projects, making them readily accessible to researchers. Prior to the availability of complete count census microdata from the MPC, researchers applied various forms of record-linking software. This essay describes the techniques used in the MPC's linking program and briefly compares this technique with those used by other researchers. The key feature of the MPC linking method is the construction of cumulative name similarity scores, based on approximately 2.5 billion record comparisons; we also use support vector mechanics to classify potential links. This article explains modifications made for the final linked datasets and includes a discussion of the role of weighting variables when using linked data.     

Surveying the Boundaries of Historical Linguistics and Archaeology: Early Settlement in South Central Africa

Drawing on evidence from South Central Africa, this paper explores two methods for linking the linguistic and archaeological records. Since the 1960s, scholars have correlated the hypothesized spatial and temporal overlaps of linguistic speech communities and pottery traditions, with varying success in the face of revisions to linguistic classifications and debates over pottery typologies. This paper assesses similar correlations between speech communities within the Bantu-Botatwe family and ceramic traditions of South Central Africa. Then, it proposes direct associations for specific activities and tools attested in both the linguistic and archaeological records in order to test correlations between pottery traditions and speech communities as well as the reliability of glottochronology. The development of a dense cluster of direct associations between the two records converging on the “when and where” of historical processes allows for the incorporation of theoretical and historical interpretations founded on one body of evidence into narratives developed from another type of data and, therefore, facilitates a “peer” engagement between the disciplines.     

Retracing Rivers and drawing swamps: Using a drawing tablet to reconstruct an historical hydroscape from army corps survey maps

Abstract

This article presents a novel geospatial approach to reconstructing and analyzing environmental change over extensive spatial and temporal scales, even in systems such as rivers and streams that are comparatively difficult to digitize. We used a drawing tablet and stylus to digitize features found on historical Army Corps maps across the spatially extensive landscape of the Lower Wabash River’s riparian zone, in Indiana and Illinois, USA. The methodology allows for an efficient reconstruction of sinuous and irregular environmental features, such as sloughs, and demonstrates the utility of digitizing historical maps to understand the evolution of surface water quantity and location across a landscape. We then compared these historical data to contemporary environmental datasets for the same study area to understand what changes have occurred over a 100?year period. This reveals that the hydroscape of the Lower Wabash River has been significantly altered by past human activity, notably through the reduction of swamps, wetlands, and sandbars, and the increase in drainage ditches and overall stream area. Notably, many of these historical alterations are not captured within current environmental datasets.
