Extreme weather events in northeastern New Brunswick (Canada) for the period 1950–2012: Comparison of newspaper archive and weather station data

In the context of global warming, changes in extreme weather and climate events are expected, particularly those associated with changes in temperature and precipitation regimes and those that will affect coastal areas. The main objectives of this study were to establish the number of extreme events that have occurred in northeastern New Brunswick, Canada in recent history, and to determine whether their occurrence has increased. By using archived regional newspapers and data from three meteorological stations in a national network, the frequency of extreme events in the study area was established for the time period 1950–2012. Of the 282 extreme weather events recorded in the newspaper archives, 70% were also identified in the meteorological time series analysis. The discrepancy might be explained by the synergistic effect of co‐occurring non‐extreme events, and increased vulnerability over time, resulting from more people and infrastructure being located in coastal hazard zones. The Mann Kendall and Pettitt statistical tests were used to identify trends and the presence of break points in the weather data time series. Results indicate a statistically significant increase in average temperatures and in the number of extreme events, such as extreme hot days, as well as an increase in total annual and extreme precipitation. A significant decrease in the number of frost‐free days and extreme cold days was also found, in addition to a decline in the number of dry days.     

Running with the ball? Making a play for sport heritage archives in Higher Education contexts

For considerable time, academia (in particular, the Humanities) has been in an intellectual, economic and pragmatic par des deux with the culture and arts sector (in this case, heritage, museums and archives). In many ways, given their respective pursuits of scientific enquiry and learning, valuable contribution to a knowledge economy, commitment to public enlightenment, and exploration of critical and creative endeavour, a relationship between the sectors makes sense. Unity notwithstanding, the relationships have become increasingly now influenced by (en)forced contextual constraints (e.g. government policy development and intervention, neoliberal market forces, structural and ideological shifts in funding acquisition and allocation, patronage changes and demands, and/or individual political priorities). Drawing on education and heritage scholarship, and theoretical frameworks of sport culture spaces, this paper examines efforts undertaken at one specific Higher Education establishment in the United Kingdom in which institutional agendas (vis-à-vis historical and cultural foci, encouraging ‘impactful’ academic activity, brand exposure, economic efficiency, and community engagement) have contoured, and become entwined with, an embryonic sport heritage and archive project. Recalling similar arrangements elsewhere, the aim of this case study is to explore how the wider education and cultural policy context have precipitated an increasingly symbiotic and dependent relationship between university and cultural/arts initiatives. The paper considers how the impetus to develop a sports-based (basketball) heritage archive and study centre reflects the current fragilities of the two sectors, yet, concomitantly, reveals the potentials that might be developed from fostering greater intellectual and pragmatic alliances. The paper concludes by advocating the practical, political and ideological usefulness of network formation, sustainability measures and continued cross-sector dialogue.     

Practices of photography on kibbutz: The case of Eliezer Sklarz

This article explores how socialist egalitarian ideology affected forms of documentation on the kibbutz in Israel, by examining its practices of photography. The study analyzes the work of one photographer, Eliezer Sklarz, and his role and function in the community, focusing on the visual content and style of his work. The article also describes the role of the kibbutz archive in promoting his work and in constructing kibbutz identity through its photographic archive, as a mechanism for creating Zionist kibbutz historiography. The study addresses the conflicted approach of kibbutz society towards photography: promoting documentation through the function of the archive on the one hand, while maintaining a dismissive role towards photography as a highbrow, middle-class practice, on the other.     

Application of Landsat satellite imagery to monitor land‐cover changes at the Athabasca Oil Sands,Alberta, Canada

A major advantage of satellite remote sensing is that the imagery acquired provides a synoptic view of the landscape. Thus, repeat coverage by the satellite on a regular basis permits the detection of changes in land‐cover over time. This study demonstrates the application of remote sensing technology to the monitoring of mining activities at the Athabasca Oil Sands region of Alberta, Canada. First, we describe the techniques used to match a time sequence of Landsat imagery, both spatially and spectrally, to ensure that the spectral changes through time are due to land‐cover variations. A series of spectral trajectories were then extracted to assess changes in land‐cover through time. Secondly, a land‐cover classification was produced from the baseline 1984 imagery and, using historic and future mine extents, the classification was analyzed to determine the proportion of each land‐cover type affected through development. Results of the analysis indicate that since 1984 there has been a larger reduction in mixedwood dense and broadleaf vegetation classes than mixedwood sparse or dense conifer stands in the area. Based on the delineations of mine‐site activity, the area of woodland and wetland habitat subject to development has increased from approximately 2,520 hectare (ha) in 1984 to 32,930 ha in 2005.     

Colonial encounters,local knowledge and the making of the cartographic archive in the Venetian Peloponnese

Current research on the cartography of the Venetian Empire rests on a state-centred perspective which reduces maps to mere technical tools in the service of maritime expansion and colonial government. In contrast, this paper argues that such an approach cannot sufficiently account for the multiple ethnocartographic transactions between Venetian authorities and local communities which defined Venetian map-making projects. Taking the seventeenth-century conquest of the Peloponnese as its focus, the paper proposes to rethink the Venetian cartographic archive as constituted through a set of socio-cultural and political practices involving both colonial surveyors and native inhabitants. By analysing the assemblage of cartographic knowledge in the context of the encounter between colonisers and colonised, the paper examines topographical surveys as the product of cross-cultural communication shaped through negotiation, competition and unequal dialogue. Ultimately, the paper aims to show the heuristic value of a dialogic approach to cartography for a better understanding of both the colonial society of the Venetian Peloponnese and the making of knowledge in Venice's overseas empire.     

ALL WRITTEN UP

This edited collection of conference papers moves historiographical debate beyond the cultural, linguistic, subjective, and archival “turns,” and beyond historiographical questions asked from the “postcolony,” to consider the historian's role as writer and in relationship to his or her (dead) subjects. Wider cultural appropriations of the Holocaust frame several contributions and underpin the ethics of historical reconstruction discussed. This review of Unsettling History considers “raising the dead” as a paradigmatic activity of Western social historians, first articulated in the European nineteenth century. Using the perspective of its editors and contributors, it argues for a yet more detailed attention to historians' acts and performances of writing.

Museums and the ‘Death of Experience’: singularity,interiority and the outside

This paper discusses a number of well-known critiques of the museum that seek to identify it as a problematic space for experience. The key argument put forward is that we can find within that analysis a critical geography around the museum that help us to understand the work that it does in relation to experience. Three spatial motifs are drawn from this analysis and discussed: the singular, the interior and the outside. The paper argues that museums since the nineteenth century have established a topos for experience based on a mimetic realism around the experience of both culture and history through the first two of these spatial expressions. Through them museums produces a fabulation of culture and history that supplements for the lack of topos for experience found within modern society as a whole. The latter spatiality – that of the outside – is found in the form of the absent–presence of the event in relation to the archiving principle of the museum, thereby continually unsettling the first two expressions and calling them into question. This dynamic reveals the museum as a space to critically think about what it does with experience and the importance of spatial analysis for that.     

Hair in the Disraeli Papers: A Victorian Harvest

The Hughenden Collection of Disraeli Papers at the Bodleian Library in Oxford comprises over 50,000 items relating to the life and work of Benjamin Disraeli and his family. This article tracks hair through the Hughenden Collection in order to explore the collecting habits of Mary Anne Disraeli. It argues that reading Mary Anne Disraeli's story through hair – both hair as object, held in an archive and hair as represented in archival text – reveals aspects of that story occluded by reading only those archival texts with self-evident documentary value. It thus makes the case for a holistic reading of the Disraeli archive, and Victorian collections of personal papers more generally, by taking Mary Anne Disraeli as its central case study. In so doing it also illuminates her story, and points to the necessity of reading the stories of forgotten women through archival silences and absences. Section I reviews recent scholarship on hair in nineteenth-century Britain in order to contextualize Mary Anne Disraeli's case. Section II anatomizes the Hughenden hair collection in order to illuminate Mary Anne's history, her impulses as a collector, and the extent to which her activities complicate scholarly narratives about the sentimental commodification of Victorian hair. Section III gestures towards recent work on the archive and material culture to tease out the consequences of her example for our reading of the archive and our understanding of the texture of Victorian ‘thing culture’ more generally.
