Combatting Road Accidents And Fatalities : The Colonial State, Voluntary Organisations, And Road Safety In Northern Rhodesia, 1940s-1964, Mbozi Santebe

Zamani: A Journal of African Historical Studies

Northern Rhodesia (now Zambia) experienced an increase in the use of motor vehicles from the late 1920s. Consequently, there was a rapid increase in the occurrence of road accidents from the 1940s onwards. The rise in cases of accidents attracted attention of the colonial state and other stakeholders that embarked on measures to improve road safety. Using a corpus of archival sources, this article examines the measures that the colonial state and voluntary organisations undertook to improve road safety in Northern Rhodesia from the 1940s to 1964. It contributes to scholarly works on the use of motor vehicles in Africa …

Dynamics Of Infanticides Among The Ngoni Of Tanzania, 1850s-1916, Andrew S. Kasambala, Oswald J. Masebo

Zamani: A Journal of African Historical Studies

Infanticide is one of the key factors in explaining changes in human populations since the antiquity. This paper examines dynamics of infanticide practices among the Ngoni of Tanzania from the late pre- colonial to the end of German colonial rule in 1916. Relying on primary and secondary sources, it argues that while infanticide remained a critical problem in Songea from the 19th century to the end of German colonialism in 1916, the context in which it was practiced and the interventions devised to alleviate it changed over time. While it was primarily practiced in Songea by pre-Ngoni communal based clans …

Criteria For Rejecting Ideas In African Philosophy : A Historical And Epistemological Analysis, Eric C. Mgalula

Zamani: A Journal of African Historical Studies

The rejection of African ideas remains a pivotal debate in African philosophy, centring on tensions between universalist epistemologies and culturally specific criteria. This study synthesizes fragmented discussions into a cohesive framework, interrogating when and why African ideas may be deemed inadequate. It critiques contemporary African scholarship that rigidly adheres to indigenous traditions under decolonial and nationalist imperatives, advocating instead for a balanced approach that harmonizes intellectual rigor with cultural authenticity. Through a historical analysis of key thinkers—from Tempels and Hountondji to Wiredu and Oyewumí—this article historicizes the evolution of evaluative criteria in African philosophy, challenging colonial legacies and romanticized traditionalism. …

Mediation Partiality And The East African Community’S ‘Quiet Diplomacy’ In The Kenyan Post-Election Crisis Of 2007/2008, Rasul A. Minja

Zamani: A Journal of African Historical Studies

This article examines the role of East African Community (EAC) in mediating the 2007/2008 Kenyan post-election crisis, analysing its engagement in regional conflict resolution. Despite its mandate to promote peace, the EAC's response was constrained by institutional weaknesses, political dynamics, and reliance on quiet diplomacy. The African Union-backed Panel of Eminent African Personalities, led by Kofi Annan, ultimately led the mediation, sidelining the EAC. Through the analysis of primary and secondary sources, the article indicates that EAC lacked a binding conflict management framework and faced decision-making delays that hindered swift intervention. The partiality of key figures, particularly President Yoweri Museveni …

Jonathan M Jackson, Visions For An African Valley: Histories Of Development In Kilombero, Tanzania Since 1877., Emanuel L. Mchome

Zamani: A Journal of African Historical Studies

Research on the history of colonial development and future-making in Tanzania has focused on the racial and class politics that influenced development visions and practices. Studies of postcolonial development history have demonstrated how state leaders and their ideologies shaped nation-building trajectories. Notwithstanding of the temporal dynamics, scholars have analysed how the flow of finance and technical assistance reveals intertwined global forces such as nationalism and the Cold War, and how foreign development assistance shaped development in Tanzania. Visions for an African Valley moves beyond this conventional analysis. Instead of employing ideological lenses in analysis, it specifically examines how colonial and …

Beyond Christianity : German Missionaries’ Heritage In Colonial Mbeya, Tanzania, 1880s-1918, Ashura Jackson Ngoya, Edward Simon Mgaya

Zamani: A Journal of African Historical Studies

This article examines the history of German missionaries in the colonial Mbeya, a southwest region of Tanzania, from the 1880s to 1918. It explores how missionaries influenced political, social, and economic changes that had a profound impact on the lives of the local population. The article investigates the secular roles of missionaries, which, although they supported evangelisation, they were not directly non- secular aspects. In doing so, the article considers missionaries' efforts in education, health, agriculture, trade, and tax collection, which sometimes led to them working as colonial intermediaries in certain areas of Mbeya. Based on primary and secondary sources, …

Engineering Inefficiencies And Technical Dependency : A Vital Lens In Understanding Power Outages In Postcolonial Tanzania, 1960s-1990s, Emanuel L. Mchome

Zamani: A Journal of African Historical Studies

This article examines how the construction of power infrastructure in the 1960s-1980s shaped the future functioning of the Tanzanian power grid from the 1990s. The article is based on oral sources and archival material collected from the Swedish National Archives in Stockholm, the Tanzania National Electric Supply Company Limited (TANESCO), the East Africana Section of the Wilbert Chagula Library at University of Dar es Salaam, the Rufiji Basin Development Authority (RUBADA) and the World Bank online sources. The article argues that engineering inefficiencies of some Western planners and builders of TANESCO’s power grid who failed to consider local ecological issues …

What’S In A Name? Re-Evaluating Early Medical Library Leaders In A Modern Context, Jennifer K. Lloyd

Library Faculty Publications

This paper will highlight two early medical librarians, Mary Louise Marshall (1893-1986) and William D. Postell, Sr (1908-1982) who were in our chapter’s region, although during their careers, SCC did not exist. While we cannot expect that historical figures have the same knowledge and values as our contemporary colleagues, we can evaluate their writings to see what internal biases were present.

Critically reappraising the work of our predecessors can be a difficult task, especially if these individuals were held in high esteem, won national awards and published important papers about medical librarianship. However, as theories are repudiated, re-evaluation is key. …

Consumptive Vampires: Notes On Nineteenth-Century Blood-Drinkers, Rachel Widmer

Early Theories On Fluid Resistance And Translation Of Euler’S “Dilucidationes De Resistentia Fluidorum”, Sylvio R. Bistafa

Euleriana

In 1763, Euler published Dilucidationes de resistentia fluidorum (Explanations on the resistance of fluids), a memoir that challenges the fluid resistance theories proposed by Isaac Newton and d’Alembert. Euler's work explores the resistance experienced by solid bodies moving through fluids, critiquing both Newton's "common rule" and d’Alembert's paradox, which predicted zero resistance for non-viscous fluids. Euler's treatise is divided into two parts: the first focuses on the mathematical modeling of fluid flow patterns, while the second addresses the calculation of fluid resistance on surfaces. Despite significant advancements, Euler's work remains constrained by the limitations of non-viscous fluid assumptions, ultimately grappling …

Between The Buffer And The Black Box: Ed(1), Invisible Text, And Delegation In Word Processing, Kai Prenger

Dissertations, Theses, and Capstone Projects

This thesis provides a media archaeological and theoretical examination of ed(1), the Unix line editor developed by Ken Thompson at Bell Labs in 1969, arguing that its approach to "invisible text" processing established lasting patterns of human-computer collaboration that persist in contemporary digital systems. Through historical research, technical analysis, and critical interpretation, this study demonstrates how ed(1) embodied a particular epistemology of text processing that appears alien in a contemporary context, but proves insightful in the age of generative text creation.

ed(1) emerged from the unique convergence of Bell Labs' collaborative research culture, severe hardware constraints of early Unix systems, …

Choked: How Decades Of Failures To Address Air Pollution And Housing Shortages Exacerbated Mortality In Pittsburgh During The Influenza Pandemic Of 1918, Virginia Montanez

Graduate Masters Theses

Pittsburgh experienced the highest death rate of all major U.S. cities during the 1918 H1N1 influenza pandemic. This record mortality was not due to inadequate, absent, or ignored nonpharmaceutical interventions and mandates. Instead, for decades prior, city officials prioritized industry at the expense of the collective health of the laboring class. They were especially egregious in permitting industrial smoke pollution and overcrowded housing to persist in immigrant-heavy working-class wards, leaving residents susceptible to respiratory disease incidence and mortality. As a result, Pittsburgh’s annual influenza and pneumonia death rates were drastically the worst in the nation to such an extent that …

Let’S Teach More Accurate And Inclusive History! The Case Of Islamic Contributions To Mathematics And Science, Nuh Aydin

Journal of Humanistic Mathematics

Schools commonly teach a history of mathematics and science that is Eurocentric. This selective version of the history of science, called Classical Narrative by some, is rooted in colonial times and mindset, and has reinforced certain negative opinions about other cultures. It ignores or downplays contributions to mathematics and sciences from non-western civilizations, and falsely attributes many scientific discoveries to European scholars. Medieval Islamic Civilization, which had strong connections to Renaissance Europe, serves as a clear example of how this narrative is distorted. Based on research on primary sources since the middle of the 20th century, we now know that …

A Practical Rule Of Divisibility By 7 In Uqlīdisī’S Kitāb Al-Fuṣūl Fī Al-Ḥisāb Al-Hindī, Müjdat Takıcak, Mertkan Şimşek

Journal of Humanistic Mathematics

There are many known examples of divisibility rules in modern mathematics. However, some of these rules are far from being practical, such as the current divisibility rule by 7. A far more useful method can be found in the work of the tenth-century Islamic mathematician Abū al-Ḥasan al-Uqlīdisī (d. 980), who proposed a divisibility rule for 7 in his treatise Kitāb al-Fuṣūl fī al-Ḥisāb al-Hindī. Compared to modern techniques, Uqlīdisī’s rule is both simpler and more practical. This article (re)introduces this rule, and provides an exposition of the mathematical reasoning that underpins it.

Stoners, Walnuts, Stockings, And Guns: A Material History Of Modern Firearms, Aiden Mashaal

History Summer Fellows

The study of firearms as material objects is notably rare among academic historians. It is relegated mainly to the pages of firearms magazines and carried out by journalists, gun collectors and enthusiasts, and gun manufacturers. Although they provide valuable information to readers outside of academia, it is long past due to observe the history of guns according to scholarly standards. This study provides a concise analysis of firearms history, focusing on the materials used in the manufacture of modern firearms—aluminum alloy and polymers. It explores the successes and failures of guns that used such materials in order to explain how …
