CFP: (Digital) Retrospectives on Historiography from Africa: Decolonization, the African press, and the uses of knowledge (open)

CFP – (Digital) Retrospectives on Historiography from Africa: Decolonization, the African press, and the uses of knowledge (open)

Editors: Noemi Alfieri (CHAM, NOVA FCSH-UAc; Africa Multiple Cluster of Excellence, U. Bayreuth), Cassandra Mark-Thiesen (Africa Multiple Cluster of Excellence, U. Bayreuth)

The history of knowledge production in Africa is a rising topic in the backdrop of growing awareness of the uneven globalization of intellectual thought. Focusing on the era of decolonization in Africa, a growing number of scholars are especially exploring historiography as read in periodicals such as pamphlets, magazines, journals or newspapers (Mark-Thiesen, Alfieri, Thioub, Coquerey-Vidrovitch and others). They provide important impetus for understanding the link between media and emancipation,
political democracy, freedom of choice, self-awareness, and selective association.

This special issue of Práticas da História reflects on contemporary epistemological possibilities and constraints in the writing of history. Therefore, it welcomes both contributions that dwell on African journals (scholarly, literary, artistic and ephemeral periodicals) from the 1950s to 1980s, and on the histories behind said periodicals. We look forward to contributions that explore different and contested visions of decolonization and future-making for the African continent and its diaspora. We also invite articles investigating differently situated historiographies from Africa: that use local vernacular by incorporating idiom, local imagery, myth and folklore; that relate to the present or the deep past. We also encourage more nuanced takes on the “nationalist historiography” that when viewed as a monolith was so dominant at the time. For instance, Pan-Africanism and Négritude, while revolutionizing the political assets of the continent, remained contested as intellectual projects. Finally, articles problematizing the current conceptualisations of such historiography as either “colonial”, “traditional”, “radical”, eurocentric”, “afrocentric”, “Africa-centred”, and so forth, are highly welcomed.

Finally, on methodology, and given the current wave of digitisation and digitality, the guest editors encourage reflections on processes of digital preservation and recirculation of historiography from Africa, including their implications for Africa-based and African diasporic knowledge production in the arts, literature, and scholarship. How about their impact on the expansion of the public arena and community empowerment? How are online platforms fostering a re-positioning, re-calibrating and re-thinking of these bodies of knowledge from Africa? And what potentialities lie in the future? In short, we are interested in contributions that dwell on contemporary and future receptions of the above-mentioned publications and journals in the digital sphere.

Proposals (maximum 500 words) must be sent by 30 April 2024 to praticashistoria@gmail.com . Proposals must be accompanied by a short biographical note. The acceptance or refusal of the proposal will be communicated by 15 May 2024. The articles of accepted proposals must be submitted by 31 July 2024. Contributions in both English and Portuguese are welcome.

CFP: Spatial Humanities 2024

Call for Papers

Spatial Humanities 2024

Bamberg University, Germany, 25th–27th Sept 2024

https://spathum.uni-bamberg.de

We are delighted to announce that the 5th Spatial Humanities conference will be held in Bamberg on September 25th to 27th 2024.

Abstract submission deadline: 15th Feb 2024

Spatial Humanities 2024 welcomes submissions on all aspects of using geospatial technologies in humanities research, methodological innovations, and applied research that develops our understanding of the geographies of the past. We welcome contributions from anyone working on computational approaches to spatial questions in the humanities and arts. These disciplines include, but are not limited to, history (including fields from social history such as historical demography and environmental history), archaeology, heritage and conservation studies, literary studies, classics, linguistics, art history, anthropology and religious studies, as well as from interdisciplinary and/or technical fields including GIS, digital humanities, computational linguistics and computer science. Abstracts should be between 750–1000 words for full papers and 500–750 words for posters.

This year the conference will take place in Bamberg, Germany, a UNESCO World Heritage Site. Accordingly, the conference will feature a special session with a focus on Spatial Humanities and Heritage. Heritage has spatial dimensions and heritage processes are linked to place: architecture and urban conservation, the listing of historic buildings, sites, cultural landscapes or heritage districts. Maps of heritage ‘assets’ and archaeological sites shape the way we perceive and understand places, as well as their cultural identity. How can these be studied to reveal cultural boundaries and exclusivity in heritage discourses? How can innovative multi-layered maps show alternative and diverse aspects of heritage?

We are delighted to announce that this year’s keynote speakers will be Francesca Ammon (University of Pennsylvania) and Ross Purves(University of Zurich).

Themes

Proposals are welcomed on, but not limited to, the following themes:

  • Gazetteers, e.g. urban, regional, national and international
  • Artificial intelligence, e.g. computer vision, NLP, deep learning, etc.
  • Spatial explorations of narratives, literary and imaginary places
  • GIS and spatial analysis including 3D modeling and spatial statistics
  • Deep mapping, experiences of places
  • Territorial representations, transgressions, subalternity and boundaries
  • Mapping mobility, spatial connections and networks
  • Linking the map and the text: mixed-method approaches
  • Geospatial ‘collections as data’, enrichment and annotation
  • Historical maps and georeferencing
  • Environmental humanities: landscapes, waterscapes and the blue humanities
  • Linked Open (Geo)Data
  • IIIF applications for maps and spatial data
  • Labs notebooks, workflows and infrastructure
  • Data mining, visualisation and the challenges of geolocation
  • Building, mapping and spatially analysing heritage inventories

Venue

Bamberg University, Markusstraße 8a, D-96047 Bamberg, Germany. The conference will be held in person.

Early Bird Rates

Full registration costs 170 €, reduced to 120 € for students including teas & coffees and lunches days. The conference dinner can be booked in addition.

Winners of the 2023 Janette Harley Prize announced

Written by Amanda Engineer, BRA Secretary

The British Records Association is delighted to announce the winners of the 2023 Janette Harley Prize. The Prize is shared between two entries as follows:

Dr Ian Forrest and Christopher Whittick (translators and editors), for The Visitation of Hereford Diocese in 1397 (Canterbury & York Society, vol. CXI, 2021)

Dr Imogen Peck (Birmingham University), for “‘Of no sort of use’?: Manuscripts, Memory, and the Family Archive in Eighteenth Century England” (Cultural and Social History, vol. 20:2 for 2023, pp.183-204), and the accompanying blog series and online resources, part of the ‘Family Archives in Early Modern England’ research project supported by the Leverhulme Trust.

These contrasting prize-winners show the breadth and value of archival records, and the different ways in which they can be studied and made more accessible.

Forrest and Whittick: Bishops learn about their dioceses through visitations. Surviving medieval visitation records are rare and of great value to historians. Bishop John Trefnant’s visitation of his diocese of Hereford in 1397 is contained in Hereford Cathedral Archives (HCA) 1779. The visitation offers unparalleled insight into social life, sexual behaviour, religious belief and practice, and gender relations during a period of religious and political turmoil, revealing how the clergy were disciplined, how English- and Welsh-speakers interacted, and how the congregation experienced worship. It is also a treasure trove of information about the fabric of local churches and the administration of parishes before the Reformation. The document is a major early source for Welsh naming practices – indeed Bishop Trefnant himself came from a Welsh area, had a Welsh name, and employed Welsh-speaking scribes in his household.

This edition is designed for the non-professional reader, being the first of the Canterbury and York Society’s 111 volumes to be published in the original Latin with a facing English translation. Conscious attempts have been made to preserve the word-order of the original as far as is consistent with fluency of translation, and to avoid technical vocabulary. The edition has greatly increased the accessibility of the manuscript, which now is consulted as a matter of course by the Diocesan Advisory Committee on questions of church fabric.

Imogen Peck: Dr Peck’s work explores the role of family archives during Britain’s long eighteenth century, especially in the formation of memory and identity. This was a period of growing archival consciousness, yet the archives curated by families have hitherto been almost entirely overlooked. This research establishes their significance. It also challenges the tendency to value the institutional and formal (and often patriarchal) over the informal and domestic.

Tracing the curation of three family collections across several generations, the article in Cultural and Social History shows how the creation and transmission of family archives played a significant role in the memory and identity of relatively modest families. The article is supported by blog posts by the author and by undergraduate and A-level students which highlight other family archives held in record offices across the country. The author has also established a ‘Family Archives’ network where historians, archivists, and members of the public working on family collections can share their work. The recordings from the network’s online workshops are available on the project website.

Highly Commended

Prof. Steven King (Nottingham Trent University) and Paul Carter (TNA), and others, In Their Own Write: Contesting the New Poor Law, 1834–1900 (McGill-Queen’s University Press, 2022).

The prize was established in memory of Janette Harley, a member of the British Records Association, who died in 2015. It is intended to raise awareness of research and achievements in the world of archives, and is awarded for the best or most original piece of published work which reflects the aims of the Association: to promote the preservation, understanding, accessibility and study of our recorded heritage for the public benefit.

A call for entries to the 2024 Janette Harley Prize will be made in April.

CFP: Ukranian Oral History Association

Ukrainian Oral History Association (UOHA)—which unites, represents, and supports oral history scholars in Ukraine and abroad—is convening the international conference UOHA-2024 “Oral History in Wartime: Academic Knowledge and the Researcher’s Responsibility.” The conference will take place June 13-15, 2024, on the grounds of and with the support of Uzhhorod National University and Zakarpattia Museum of Folk Architecture and Life (Uzhhorod, Ukraine), the Huculak Chair in Ukrainian Culture and Ethnography, Canadian Institute of Ukrainian Studies at the University of Alberta (Edmonton, Canada), and the Ukrainian Institute of National Memory (Kyiv, Ukraine).

With the beginning of the full-scale phase of the Russian war against Ukraine that started on February 24, 2022, many activists, community-based scholars, academics, museum workers, journalists, and archivists, as well as diverse national and international research teams, began actively recording and documenting war-focused personal testimonies and accounts. Many engaged in this demanding work lacked appropriate training or experience in ethically sound interviewing methods. The above challenges and the unprecedented number of teams documenting testimonies of the Russian-Ukrainian war believed to be already the most documented modern war call for an open dialogue on what constitutes sound research and research practices in the oral history of wartime.

The conference is called to address and provide answers to the following questions. What is the difference between the academic standards of oral history and other initiatives that gained popularity with the beginning of the full-scale Russian invasion of Ukraine? What challenges of documenting events in the context of an ongoing war do the researchers face in their work? How should one address the questions of safety and adhere to ethical norms during interviewing? What are the personal, legal, and professional responsibilities of researchers pursuing the oral history of the unfolding war? What are the best practices for sharing scholarly accomplishments and academic output of Ukrainian oral historians on the international stage?

Thematic directions of the conference are:
● researcher’s responsibility in the process of preparation, implementation, analysis, and presentation of the results of the oral history project;
● archiving of oral histories—ethically, safely, and responsibly;
● oral history: from an umbrella term to the diversification of research practice;
● oral history and the production of new academic knowledge;
● the researcher as a (co)creator of oral history testimony.

Applications for participation in the conference will be accepted until March 15, 2024. To apply, fill in the Google form: Міжнародна наукова конференція УАУІ-2024 “УСНА ІСТОРІЯ У ВОЄННИЙ ЧАС: НАУКОВЕ ЗНАННЯ І ВІДПОВІДАЛЬНІСТЬ ДОСЛІДНИКА” (13-15 червня 2024 року, Ужгород, Україна) (google.com).
Participants will be selected on a competitive basis. A priority consideration will be given to members of the Ukrainian Oral History Association. Travel within Ukraine, accommodation, and meals will be provided by the conference organizers. Working languages: Ukrainian, English. Based on the results of the conference, a special issue of the “Scientific Bulletin of the Uzhhorod University. Series: History” (category B) is proposed. The requirements for the publications will be sent after the completion of the selection of applications on April 15, 2024.

We are looking forward to receiving your applications!

CFP: Sustainability in Practice: DIY Repair, Reuse and Innovation

Sustainability in Practice: DIY Repair, Reuse and Innovation
30 October–2 November 2024 
Estonian National Museum, Tartu, Estonia
Conference webpage: http://enmconferences.ee/sustainability-2024

This conference addresses ecological sustainability through do it yourself (DIY) practices, and through consumer behaviour and heritage. The focus on DIY repair, reuse and vernacular innovation seeks to examine sustainability in the context of everyday life and domestic and community settings. By bringing together anthropological, ethnological, sociological and craft studies perspectives, the conference aims to show and discuss contemporary, traditional and vernacular sustainable practices.

Repair, reuse and repurpose of diverse commodities and materials, and vernacular innovation, are today increasingly perceived as part of sustainable consumption culture. However, the role and meaning of these practices have changed over time, depending on social, economic and political environments. Facing the global climate crisis, we are looking for lessons from the past and present for more sustainable and resilient ways of life.

Keynote speakers:
Prof. Steven J. Jackson (Cornell University)
Prof. Tomás Errázuriz (Universidad Andrés Bello, Campus Creativo)
Assoc. prof. Ricardo Greene (Universidad de las Américas)

We invite presentations, workshops and documentaries that explore various forms of DIY practice, solutions, innovation and material culture related to sustainability in a variety of settings and regions. Apart from academics, experts from memory institutions and craft scholars, this conference also invites activists, craftsmen and designers to share their experience and knowledge.

Possible topics include:

  • Repair and maintenance
  • Reuse and repurpose
  • Vernacular innovation and invention
  • The material culture of sustainability
  • Sustainable and resilient lifestyles and communities
  • Forms of activism (for example, repair cafés, the right to repair movement, low-tech, etc.)
  • Heritage and applied heritage
  • The role of museums and memory institutions in maintaining and promoting sustainability
  • Insights from activists and craftsmen or designers

The deadline for submission is 31 March 2024. Please send an abstract (200–300 words) of the presentation, workshop or documentary film with the title and your details. In addition, for workshops please add special requirements, and for documentaries please add online access to the film with English subtitles.

Please send your submission to the conference e-mail: sustainability@erm.ee

The conference is organised by the Estonian National Museum in collaboration with the Washing Machine Made of Beetroot joint exhibition project, curated by the Estonian Road Museum, the Estonian Agricultural Museum, and the Tartu City Museum. The conference programme involves organised tours of the exhibition on invention, ingenuity, recycling and DIY mentality, and visits to various public repair workshops in Tartu.

The conference and the exhibition are part of and supported by the European Capital of Culture Tartu 2024 programme.
